Background: Catatonia is a potentially life-threatening condition that is characterized by psychiatric and motor disturbances, such as negativism, hypomotility, bradykinesia, and unusual movements. The diagnosis is based on clinical examination and occurs in both pediatric and adult patients and is associated with an increased mortality. Catatonia is associated with psychiatric illnesses such as schizophrenia, major depression, encephalitis, and bipolar disorder. The physiopathology of catatonia is complex and not fully understood. There is an ongoing debate in the medical community whether catatonia is an independent syndrome, or secondary to other mental illnesses. This case presentation is unique, as there are few reports describing cases of isolated catatonic syndrome in the absence of any other psychiatric or medical condition with a delayed onset caused by recreational drug abuse., Case Presentation: We present the case of a 17-year-old Caucasian athletic girl with no previous contact with child and adolescent psychiatry, nor any previous drug abuse. After recreational intake of drugs, there was a delay of approximately 7 days, before the patient searched care with symptoms that were at a later stage recognized as catatonia. Treatment with a high dose of lorazepam in combination with memantine and lithium resulted in a regression of the symptoms. After 6 weeks the patient could be discharged from the hospital almost fully recovered., Conclusions: An acute onset of psychomotor symptoms without any previous history of mental illnesses must be addressed early as a potential catatonic syndrome. Delayed onset of catatonic symptoms after intake of drugs should not be overlooked, and we here suggest that mephedrone might be capable of inducing delayed catatonia. It is feasible to use memantine as an adjuvant to the treatment of catatonia in adolescents., Competing Interests: Declarations Ethics approval and consent to participate The patient, who had recently turned 18 years old at the time of discharge from Uppsala University Hospital, has signed a written consent regarding this case report.

Background: Benzodiazepines are commonly prescribed for post-acute ischemic stroke for anxiety, insomnia, and agitation. While guidelines discourage use in those aged ≥65 years, little is known about prescription patterns at the national level., Methods: We analyzed a 20% sample of US Medicare claims from April 1, 2013, to September 30, 2021. We selected beneficiaries aged ≥65 years discharged alive following an acute ischemic stroke who had traditional Medicare coverage and 6 months' prior enrollment in Parts A (hospital insurance), B (Medical insurance), and D (drug coverage). We excluded those with prior benzodiazepine prescriptions, self-discharges, or discharge to skilled nursing facilities. We examined demographics, comorbidities, first prescription days' supply, cumulative incidences of benzodiazepine first prescription fills within 90 days after discharge, and geographic and yearly trends., Results: We included 126 050 beneficiaries with a mean age of 78 years (SD, 8); 54% were female and 82% were White. Within 90 days, 6127 (4.9%) initiated a benzodiazepine. Among new prescriptions, lorazepam (40%) and alprazolam (33%) were the most prescribed. Most (76%) of first fills had a day's supply over 7 days and 55% between 15 and 30 days. Female initiation rates were higher (5.5% [95% CI, 5.3-5.7]) than male initiation rates (3.8% [95% CI, 3.6%-3.9%]). Rates were highest in the southeast (5.1% [95% CI, 4.8%-5.3%]) and lowest in the midwest (4.0% [95% CI, 3.8%-4.3%]), with a modest nationwide initiation decline from 2013 to 2021 (cumulative incidence difference, 1.6%)., Conclusions: Despite a gradual decline in benzodiazepine initiation from 2013 to 2021, we noted excessive supplies in prescriptions post-acute ischemic stroke discharge, underscoring the need for improved policies., Competing Interests: Dr Hsu receives support from the National Institutes of Health, the Agency for Healthcare Research and Quality, Brandies University, Altmed, Cambridge Health Alliance, Columbia University, Invitrx, and the University of South Carolina and reports no conflict of interest.

Background: Electroconvulsive therapy (ECT) is considered to be a treatment of choice in patients with catatonia, who do not respond to lorazepam, irrespective of the underlying aetiology. Although, significant data is available for successful use of ECT in patients with catatonia secondary to affective and psychotic disorders, little information is available for use of ECT in organic catatonia., Aim: To assess demographic and clinical profile of patients with organic catatonia receiving ECT., Methodology: Using a retrospective study design, ECT register of the department was reviewed for the period of 2019-2023 to identify the patients with organic catatonia, who received ECT. The treatment records of these patients were reviewed to extract the demographic and clinical profile., Results: During the study period, out of the 926 patients who received ECT, 12 (1.3 %) patients diagnosed with organic catatonia received ECT. The mean age of study sample was 41.67 (SD- 20.68) years and mean number of ECTs given in a course of ECT were 8 (SD- 4.3). In majority of the patients, ECT was considered after the failure of lorazepam challenge test. Majority (75 %) of the patients showed good response to ECT and only 16.67 % of the patients experienced complications during the course of ECT., Conclusion: ECT is an effective and well-tolerated treatment for organic catatonia., Competing Interests: Declaration of Competing Interest None., (Copyright © 2024 Elsevier B.V.

Background: Malignant catatonia is a potentially lethal neuropsychiatric syndrome characterized by psychomotor abnormalities and autonomic instability. Patients with this syndrome require immediate treatment. Various psychiatric conditions and nonpsychiatric medical problems can trigger malignant catatonia. Use of psychostimulant drugs, including methamphetamine and cocaine, has not been previously reported to precipitate malignant catatonia., Case Summary: This case concerns a 35-year-old man hospitalized for psychosis due to methamphetamine and cocaine intoxication. He developed malignant catatonia the day after admission. He was treated with lorazepam for malignant catatonia, and his blood pressure was controlled with clonidine. Over 7 days, his condition resolved, and his mental status and vital signs returned to baseline. He was discharged to the community in stable condition and has returned to his baseline functional status. He remains free of catatonia and has maintained abstinence from methamphetamine and cocaine., Conclusions: Acute intoxication with psychostimulant drugs is a possible trigger for malignant catatonia, and administration of high potency first-generation antipsychotics in this setting may increase the risk. Patients hospitalized for stimulant intoxication should be monitored for signs and symptoms of catatonia, and D 2 receptor antagonist medications should be used with caution in this population. Our case supports the potential role of altered dopamine and norepinephrine signaling in the pathogenesis of malignant catatonia. The patient provided written and verbal consent to publish the information in this case report., Competing Interests: The authors report no conflicts of interest., (Copyright © 2024 American Society of Addiction Medicine.)

Background: Risk factors for alcohol withdrawal delirium include heavy drinking, prior alcohol withdrawal delirium or convulsions, nondrug sedative use, and a history of tachycardia, withdrawal, and infections., Case Presentation: A 76-year-old man with a history of heavy drinking and type 2 diabetes was hospitalized for hypothermia, rhabdomyolysis, and acute renal failure after a typhoon. He developed alcohol withdrawal symptoms 24 h after his last drink, leading to severe withdrawal delirium characterized by restlessness, delusions, and altered consciousness. Treatment included lorazepam, in addition to comprehensive care for his physical condition. His condition fluctuated, especially at night, with his psychiatric symptoms exacerbated by his physical illnesses, suggesting delirium due to the coexistence of severe and multiple physical illnesses. After 44 days, following substantial improvements in both mental and physical health with perospirone, the patient was discharged., Conclusion: This case emphasizes the need for multidisciplinary collaboration in the treatment of such patients, especially during disasters, and the importance of long-term monitoring for elderly patients with alcohol dependence syndrome after a disaster., (© 2024 The Authors.

Background: Benzodiazepines are the preferred treatment for alcohol withdrawal. Phenobarbital is an alternative in the setting of prescriber expertise or benzodiazepine contraindication., Objective: To evaluate the efficacy and safety of a phenobarbital dosing strategy aimed at treating a spectrum of alcohol withdrawal symptoms across various patient populations., Methods: Retrospective review of patients admitted with concerns of alcohol withdrawal between May 2018 and November 2022. Patients were separated into a before-after cohort of lorazepam or phenobarbital. The primary outcome was hospital length of stay (LOS). Secondary outcomes were intensive care unit (ICU) LOS, escalation of respiratory support, increased level of care (LOC), and incidence of delirium tremens and/or seizures., Results: Two hundred and seventy-seven patients received lorazepam and 198 received phenobarbital. Hospital LOS was longer in the phenobarbital cohort compared with the lorazepam cohort (6.9 vs 9.3 days). There was no difference in ICU LOS. Level of care increases were fewer in the phenobarbital cohort (4 events vs 19 events). There were higher rates of non-invasive respiratory interventions in the lorazepam cohort and higher rates of mechanical ventilation in the phenobarbital cohort. Utilization of phenobarbital was attributed to a reduction in delirium tremens and seizures., Conclusion and Relevance: This study is novel because of the broad application of a phenobarbital order set across multiple levels of care and patient admission diagnoses. A risk targeted split load intravenous phenobarbital order set can safely be administered to patients with fewer escalations of care, seizures, delirium tremens, and respiratory care escalation., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: The aim of the study is to describe prepubescent catatonia in very young children, which is poorly documented in the current literature and, as a result, overlooked in medical settings., Methods: We examined a convenience sample of 10 patients at an academic center who were younger than 12 years and met criteria for catatonia. After institutional review board approval, we extracted from the electronic medical records demographic and diagnostic information, comorbidity, developmental history, and laboratory testing. Bush Francis Catatonia Rating Scales at initial presentation and other symptomatology were gathered in addition to treatment received. Fifty percent of patients in this group were seen and diagnosed with catatonia at their presentation in an outpatient clinic, whereas the remaining 50% were diagnosed upon hospitalization, by the psychiatry consultation liaison team., Results: All patients but one was diagnosed with a comorbid condition before the diagnosis of catatonia, including 70% with a previous diagnosis of autism spectrum disorder. Three patients had concurrent anti-N-methyl-D-aspartate receptor encephalitis, and one initially presented with seizures. All patients were treated for catatonia with lorazepam, and two patients additionally received electroconvulsive therapy. Regardless of the presence of early regression invariably associated with an autism spectrum diagnosis, secondary symptoms of regression were noted in each case at the time of diagnosing catatonia., Conclusions: Similar to previous observations in adolescents, prepubescent catatonia seems strongly associated with neurodevelopmental disorders, secondary regression, variability in presentation, and comorbidity with other neurological conditions. Delayed recognition of catatonia can hinder rapid and effective treatment in young children., Competing Interests: The authors have no conflicts of interest or financial disclosures to report., (Copyright © 2023 Wolters Kluwer Health, Inc.

Objective: Catatonia is a neuropsychiatric disorder associated with changes in behavior and affect. In adults, catatonia can respond rapidly to treatment with benzodiazepines as part of the "lorazepam challenge test." The acute effectiveness of benzodiazepine treatment in pediatric catatonia, however, has received less study. This study reports catatonia severity as measured by the Bush Francis Catatonia Rating Scale (BFCRS) in pediatric patients before and after treatment with lorazepam., Methods: Multicenter retrospective cohort study from 1/1/2018 to 6/1/2023 of patients aged 18 and younger with a clinical diagnosis of catatonia and assessment using the BFCRS before and after treatment with lorazepam., Results: Among 54 patients, median age was 16, and 26 (48.1 %) were female. Neurodevelopmental disabilities were present in 24 (44.4 %) of patients. Prior to treatment, patients had a mean BFCRS score of 16.6 ± 6.1, which significantly reduced to 9.5 ± 5.3 following treatment with lorazepam (mean paired difference 7.1; t = 9.0, df = 53, p < 0.001), representing a large effect size (Hedges's g = 1.20; 95 % CI: 0.85 to 1.55). No significant association was found between lorazepam dose or route of administration and clinical response, nor were age, sex, study site, the presence of a neurodevelopmental disorder, the presence of hyperactive catatonic features, or the time between treatment and reassessment associated with post-treatment BFCRS., Conclusions: Lorazepam resulted in a rapid improvement in BFCRS score in pediatric patients, with a large effect size. Further research is needed into optimal dosing and route of administration of the lorazepam challenge test in pediatric patients., Competing Interests: Declaration of competing interest JL receives funding from Harvard Medical School Dupont Warren Fellowship and Livingston Awards, the Rappaport Foundation, and the Foundation for Prader-Willi Research.

Catatonia is a neuropsychiatric disorder characterized by motor, affective and cognitive-behavioural signs, which lasts from hours to days. Intensive research over the past two decades has led to catatonia being recognized as an independent diagnosis in the International Classification of Diseases, 11th Revision (ICD-11) since 2022. Catatonia is found in 5-18% of inpatients on psychiatric units and 3.3% of inpatients on medical units. However, in an unknown number of patients, catatonia remains unrecognized and these patients are at risk of life-threatening complications. Hence, recognizing the symptoms of catatonia early is crucial to initiate appropriate treatment to achieve a favourable outcome. Benzodiazepines such as lorazepam and diazepam, electroconvulsive therapy, and N-methyl-D-aspartate antagonists such as amantadine and memantine, are the cornerstones of catatonia therapy. In addition, dopamine-modulating second-generation antipsychotics (for example, clozapine and aripiprazole) are effective in some patient populations. Early and appropriate treatment combined with new screening assessments has the potential to reduce the high morbidity and mortality associated with catatonia in psychiatric and non-psychiatric settings., (© 2024.

Background: Patients experiencing alcohol withdrawal often receive care on inpatient mental health units. Registered nurses on one such unit had several concerns and questions about the existing alcohol withdrawal symptom management order set. To address these issues, a multidisciplinary team including nurses, psychiatrists, and pharmacists was formed., Objectives: The aims for this project were to review and revise the existing order set, educate staff, implement the changes, and evaluate outcomes., Methods: The Plan-Do-Study-Act quality improvement framework guided the project. Five phases were completed to revise the order set and implement: a survey of nurses on the unit, community practice evaluation, and order set revisions. A simulation escape room facilitated nursing education. Patient records were reviewed to identify adverse events., Results: Diazepam replaced lorazepam as the primary medication choice, and a front-loading protocol was added. Order set clarity was improved, education increased nursing staff confidence to competently complete a patient assessment with the Clinical Institute Withdrawal Assessment Alcohol Scale Revised, and no adverse patient events occurred after implementation., Conclusion: A revised order set for symptom management of patients experiencing alcohol withdrawal reflected up-to-date evidence while maintaining patient safety. All nurses agreed the revised order set was clear and easy to follow; pharmacists and physicians were satisfied with the revisions. Implications for leaders include having a multidisciplinary team, sufficient resources to answer clinical questions, and regular discussions by all involved disciplines to review any adverse events as well as newly published evidence. Close monitoring of patients early in implementation is recommended to detect adverse events., Competing Interests: The authors report no conflicts of interest.

Malignant catatonia (MC) is a complex, life-threatening condition characterized by motor dysregulation and autonomic instability, which requires prompt and effective treatment. There are some limitations to the current recommendations for treating MC, including barriers to receiving ECT, failure to respond to benzodiazepines, or benzodiazepine intolerance. To the authors' knowledge, there are 3 case reports in the literature describing the use of amantadine in the treatment of MC. We present the case of a 51-year-old female with a history of multiple medical and psychiatric conditions who was admitted to the hospital for altered mental status. During her admission, she developed symptoms that raised concern about MC, which was initially managed with lorazepam. However, due to concerns about severe respiratory compromise, lorazepam was discontinued, and the patient was started on liquid amantadine. She showed marked reduction in the symptoms of malignant catatonia, and the autonomic instability resolved after she was started on amantadine. The patient was eventually discharged home with outpatient follow-up scheduled. Our case report shows successful treatment of MC with liquid amantadine in a patient who was unable to tolerate escalating doses of benzodiazepines. The positive response to amantadine suggests that it may be a useful treatment option for MC. While further studies are needed, clinicians should consider the use of amantadine in the treatment of MC, especially in patients who are unable to tolerate benzodiazepines, who have failed to respond to treatment with benzodiazepines, or who are being treated in institutions where the availability of ECT is limited. Amantadine may be more readily accessible given its multiple formulations and wide availability., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Catatonia is a highly prevalent syndrome in patients presenting with major neurocognitive disorders (dementia). In this study, we aim to provide a comprehensive description of the clinical and therapeutic aspects of catatonia in patients with dementia., Method: This descriptive study, conducted between September 2015 and June 2022, collected data from 25 patients diagnosed with dementia, out of 143 patients treated for catatonia in our specialized psychiatry department. We collected sociodemographic, clinical and treatment data for each patient., Results: Dementia patients constituted 17% of the catatonic cases. Predominantly female, the cohort had a mean age of 65. Diagnoses included Alzheimer's (4 patients, 17%) and Parkinson's (1 patient, 4%) diseases, Lewy body dementia (5 patients, 21%), vascular dementia (4 patients, 17%) and frontotemporal lobar degeneration (10 patients, 41%). The mean Bush-Francis Catatonia Rating Scale score upon admission was 20/69. Overall, complete remission of catatonia was achieved in 75% of patients (n=18), with only 13% (n=3) responding to lorazepam alone, while others required additional interventions such as electroconvulsive therapy (ECT) and/or amantadine. Vascular dementia was predominantly observed in cases resistant to treatment., Conclusion: The findings indicate a frequent co-occurrence of catatonia and dementia, highlighting treatability yet suggesting a potential for resistance to lorazepam, which varies by dementia diagnosis. Investigating the mechanisms underlying this resistance and the variability in treatment response is crucial for developing more precise therapeutic strategies., Competing Interests: Declaration of Competing Interest The authors report no financial disclosures or conflicts of interest., (Copyright © 2024 Elsevier B.V.

Introduction: Catatonia, a psychomotor disorder characterized by diverse clinical signs, including stupor and mutism, remains elusive in its causes and a challenge to diagnose. Moreover, it is often underrecognized due to its resemblance to disorders of consciousness. However, when diagnosing catatonia, an antipsychotic medication may exacerbate the condition. The first-line treatment typically includes benzodiazepines and/or electroconvulsive therapy (ECT)., Case Report: A 60-year-old woman with systemic lupus erythematosus (SLE) and epilepsy presented with catatonic stupor. Despite stable treatment, she experienced an acute deterioration in consciousness, requiring hospitalization. Her condition improved markedly following a benzodiazepine challenge, as documented on EEG. This improvement was short-lived, but a second benzodiazepine challenge restored her from E1V1M1 (stupor) to E4V5M6 within minutes, as documented by a video recording. The patient was treated with lorazepam 1.5 mg/day orally and did not experience further relapses., Discussion: The diagnosis of catatonia had been based on her scores on the Bush-Francis Catatonia Rating Scale (BFCRS; Screening, 6/14; Severity, 19), despite meeting only two DSM-5 criteria for catatonia (stupor and mutism). The diagnosis was supported by EEG and video documentation, excluding other potential differential diagnoses such as nonconvulsive status epilepticus and encephalopathy. Additional quantitative EEG analyses indicated that benzodiazepine administration increased brainwide alpha and beta band power significantly, suggesting that the benzodiazepine normalized attention, consciousness, and long-range synchronization. This report additionally emphasizes the significance of video recordings in managing catatonia, and it helps in accurately tracking symptoms, documenting comprehensively, and improving patient understanding, which is crucial for treatment adherence., (© 2024 The Authors.

Catatonia is a complex syndrome with unique cognitive, psychomotor, and mood features. Mannerisms and stereotypies are catatonic signs that have been extensively observed and described in the literature, mostly in the context of movements or motor acts. Stereotypies are commonly described as repetitive psychomotor or verbal acts with the abnormality not inherent in the act but in its frequency. Mannerisms, like stereotypies, are repetitive psychomotor or verbal acts, but they are fundamentally odd in nature. Recently, several reports have described these phenomena in the context of complex behaviors, such as eating and drinking. Identification and appreciation of personal and cultural norms, in addition to a careful analysis of behavioral processes and actions, are important tools for clinicians to identify these potentially elusive and often missed patterns of behavior in patients with catatonia. We present the case of a 30-year-old male with a psychiatric history of treatment-resistant, recurrent major depressive disorder with psychotic features who presented to the inpatient psychiatric unit with signs of catatonia, including repeated, purposeless eating. The patient's chart was reviewed, and a literature review was conducted using PubMed with the keywords catatonia, stereotypies, mannerisms, and hyperphagia. The patient, who was diagnosed with catatonia and expressed hyperphagia as a stereotypy, responded to lorazepam. This case shows that hyperphagia may present as a stereotypy in patients with catatonia., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: Benzodiazepines are the gold standard for treatment of alcohol withdrawal, yet the selection of a preferred benzodiazepine is limited due to a lack of comparative studies., Objectives: The primary objective of this study was to compare the efficacy and safety of injectable lorazepam (LZP) and diazepam (DZP) in the treatment of severe alcohol withdrawal syndrome (AWS)., Methods: Retrospective cohort study of adult patients admitted to an intensive care unit with a primary diagnosis of AWS. Subjects who received at least 12 LZP equivalent units (LEU) of injectable DZP or LZP within 24 hours of initiation of the severe AWS protocol were included. The primary outcome was time with Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) scores at goal over the first 24 hours of treatment., Results: A total of 191 patients were included (DZP n = 89, LZP n = 102). Time with CIWA-Ar scores at goal during the first 24 hours was similar between groups (DZP 12 hours [interquartile range, IQR, = 9-15] vs LZP 14 hours [IQR = 10-17]), P = 0.06). At 24 hours, LEU requirement was similar (DZP 40 [IQR = 22-78] vs LZP 32 [IQR = 18-56], P = 0.05). Drug cost at 24 hours was higher in the DZP group ($204.6 [IQR = 112.53-398.97] vs $8 [IQR = 4.5-14], P < 0.01)., Conclusion and Relevance: DZP or LZP are equally efficacious for the treatment of severe AWS. LZP may be preferred due to cost but both medications can be used interchangeably based on availability., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Purpose: It is unclear how the evidence from clinical trials best translates into complex clinical settings. The aim of this quality improvement (QI) project was to change prescribing practice for rapid tranquillization in inpatient mental health care services examining the effectiveness of the Plan-Do-Study-Act (PDSA) method., Methods: A prospective QI project was conducted to ensure that intramuscular (IM) diazepam was substituted with IM lorazepam for benzodiazepine rapid tranquillization in inpatient mental health care. We monitored the prescription and administration of medication for rapid tranquillization before (N = 371), during (N = 1130) and after (N = 364) the QI intervention. Seven iterative PDSA cycles with a multiple-component intervention approach were conducted to gradually turn the prescribing practice in the desired direction. Simultaneously, a standard monitoring regimen was introduced to ensure patient safety., Results: Lorazepam administrations gradually replaced diazepam during the intervention period which was sustained post-intervention where lorazepam comprised 96% of benzodiazepine administrations for rapid tranquillization. The mean dose of benzodiazepine administered remained stable from pre (14.40 mg diazepam equivalents) to post (14.61 mg) intervention phase. Close to full compliance (> 80%) with vital signs monitoring was achieved by the end of the observation period., Conclusion: It was possible to increase the quality of treatment of acute agitation in a large inpatient mental health care setting using a stepwise approach based on iterative PDSA cycles and continuous data feedback. This approach might be valuable in other prescribing practice scenarios with feedback from local stakeholders and opinion leaders., (© 2023.

This review aimed to examine the place of benzodiazepines, specifically lormetazepam, in the treatment of insomnia, including during pregnancy or in patients with psychodermatoses. PubMed was searched for the term "lormetazepam" in association with MeSH terms encompassing anxiety, insomnia/sleep disorders, pregnancy/gestation, and psychodermatoses/skin disorders. English-language articles up to 31 July 2022 were identified. Ad hoc searches for relevant literature were performed at later stages of review development. Multiple randomized, placebo-controlled studies have demonstrated that lormetazepam dose-dependently increases total sleep time, decreases wakefulness over a dosing range of 0.5-2.0 mg, and improves subjective assessments of sleep quality. Lormetazepam is as effective as other benzodiazepines in improving sleep duration and quality, but is better tolerated than the long-acting agents with minimal next-day effects. Benzodiazepines can be used as short-term monotherapy at the lowest effective dose during the second or third trimesters of pregnancy; lormetazepam is also a reasonable choice due to its limited transplacental passage. Insomnia associated with skin disorders or pregnancy can be managed by effective symptom control (especially itching), sleep hygiene, treatment of anxiety/depression, and a short course of hypnotics., (Copyright © 2024 The Author(s).

Background: Seizure clusters, prolonged seizures, and status epilepticus are life-threatening neurological emergencies leading to irreversible neuronal damage. Benzodiazepines are current evidence-based rescue therapy options; however, recent investigations indicated the prescription of mainly unsuitable benzodiazepines and inappropriate use of rescue medication., Objective: To examine current use, satisfaction, and adverse events concerning rescue medication in patients with epilepsy in Germany., Patients and Methods: The study was conducted at epilepsy centres in Frankfurt am Main, Greifswald, Marburg, and Münster between 10/2020 and 12/2020. Patients with an epilepsy diagnosis were assessed based on a questionnaire examining a 12-month period., Results: In total, 486 patients (mean age: 40.5, range 18-83, 58.2 % female) participated in this study, of which 125 (25.7 %) reported the use of rescue medication. The most frequently prescribed rescue medications were lorazepam tablets (56.8 %, n = 71 out of 125), buccal midazolam (19.2 %, n = 24), and rectal diazepam (10.4 %, n = 13). Seizures continuing for over several minutes (43.2 %, n = 54), seizure clusters (28.0 %, n = 35), and epileptic auras (28.0 %, n = 35) were named as indications, while 28.0 % (n = 35) stated they administered the rescue medication for every seizure. Of those continuing to have seizures, 46.0 % did not receive rescue medication. On average, rescue medication prescription occurred 7.1 years (SD 12.7, range 0-66) after an epilepsy diagnosis., Conclusions: Unsuitable oral benzodiazepines remain widely prescribed for epilepsy patients as rescue medication. Patients also reported inappropriate use of medication. A substantial proportion of patients who were not seizure-free did not receive rescue medication prescriptions. Offering each patient at risk for prolonged seizures or clusters of seizures an individual rescue treatment with instructions on using it may decrease mortality and morbidity and increase quality of life. ., Competing Interests: Conflict of interest statement M.

Background: Catatonia is a rare neuropsychiatric condition; it is estimated that around 10% of patients with mood disorders present signs and symptoms of catatonia. A catatonic syndrome is characterised by mutism, negativism, rigidity, and stupor., Case Report: We report the case of a 59-year-old patient with a medical history of bipolar disorder who was admitted to the internal medicine service due to a seizure episode. During hospitalisation, the patient presented significant worsening of her clinical condition, showing marked symptoms of stupor and catatonia. Once the neurological and metabolic etiologies of altered mental status had been ruled out, pharmacological treatment with high doses of lorazepam was started. The patient had a complete clinical remission, and her evolution was favourable without any complications. Electroconvulsive therapy was recommended as a definitive treatment., Conclusions: The diagnosis of catatonia is a challenge for both hospitalists and psychiatrists due to the clinical presentation of catatonia. In reporting this clinical case, we want to emphasise the importance of taking into account the catatonic syndrome in our differential diagnoses in patients with altered mental status., (Copyright © 2022 Asociación Colombiana de Psiquiatría.

Background: Phenobarbital has been used in the emergency department (ED) as both a primary and adjunctive medication for alcohol withdrawal, but previous studies evaluating its impact on patient outcomes are limited by heterogenous symptom severity., Objectives: We compared the clinical outcomes of ED patients with moderate alcohol withdrawal who received phenobarbital, with or without benzodiazepines, with patients who received benzodiazepine treatment alone., Methods: This is a retrospective cohort study conducted at a single academic medical center utilizing chart review of ED patients with moderate alcohol withdrawal between 2015 and 2020. Patient encounters were classified into two treatment categories based on medication treatment: phenobarbital alone or in combination with benzodiazepines vs. benzodiazepines alone. Chi-square test or Fisher's exact was used to analyze categorical variables and the Student's t-test for continuous data., Results: Among the 287 encounters that met inclusion criteria, 100 received phenobarbital, compared with 187 that received benzodiazepines alone. Patients who received phenobarbital were provided significantly more lorazepam equivalents. There was a significant difference in the percentage of patient encounters that required admission to the hospital in the phenobarbital cohort compared with the benzodiazepine cohort (75% vs. 43.3%, p < 0.001). However, there was no difference in admission level of care to the floor (51.2% vs. 52.0%), stepdown (33.8% vs. 28%), or intensive care unit (15% vs. 20%), respectively., Conclusions: Patients who received phenobarbital for moderate alcohol withdrawal were more likely to be admitted to the hospital, but there was no difference in admission level of care when compared with patients who received benzodiazepines alone. Patients who received phenobarbital were provided greater lorazepam equivalents in the ED., Competing Interests: Declaration of competing interest None., (Copyright © 2023 Elsevier Inc.

Background: Alcohol withdrawal syndrome (AWS) represents significant cost to the hospitalized trauma population from a clinical and financial perspective. Historically, AWS has been managed with benzodiazepines. Despite their efficacy, benzodiazepines carry a heavy adverse effect profile. Recently, benzodiazepine-sparing protocols for the prophylaxis and treatment of AWS have been used in medical patient populations. Most existing benzodiazepine-sparing protocols use phenobarbital, while ours primarily uses gabapentin and clonidine, and no such protocol has been developed and examined for safety and efficacy specifically within a trauma population., Methods: In December of 2019, we implemented our benzodiazepine-sparing protocol for trauma patients identified at risk for alcohol withdrawal on admission. Trauma patients at risk for AWS admitted to an academic Level 1 trauma center before (conventional) and after (benzodiazepine-sparing [BS]) protocol implementation were compared. Outcomes examined include morphine milligram equivalent dosing rates and lorazepam equivalent dosing rates as well as the Clinical Institute Withdrawal Assessment for Alcohol, revised (CIWA-Ar) scores, hospital length of stay, intensive care unit length of stay, and ventilator days., Results: A total of 387 conventional and 134 benzodiazepine sparing patients were compared. Injury Severity Score (13 vs. 16, p = 0.10) and admission alcohol levels (99 vs. 149, p = 0.06) were similar. Patients in the BS pathway had a lower maximum daily CIWA-Ar (2.7 vs. 1.5, p = 0.04). While mean morphine milligram equivalent per day was not different between groups (31.5 vs. 33.6, p = 0.49), mean lorazepam equivalents per day was significantly lower in the BS group (1.1 vs. 0.2, p < 0.01). Length of stay and vent days were not different between the groups., Conclusion: Implementation of a benzodiazepine-sparing pathway that uses primarily clonidine and gabapentin to prevent and treat alcohol withdrawal syndrome in trauma patients is safe, reduces the daily maximum CIWA-Ar, and significantly decreases the need for benzodiazepines. Future studies will focus on outcomes affected by avoiding AWS and benzodiazepines in the trauma population., Level of Evidence: Therapeutic/Care Management; Level IV., (Copyright © 2023 American Association for the Surgery of Trauma.)

Abstract: Catatonia is an underrecognized disorder that has been widely described as a psychomotor syndrome, with little emphasis on its thought and cognitive dimensions. The current Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision describes only motor and behavioral presentations, whereas a few catatonia scales describe only one form of thought disorders, which is thought perseveration. Thought blocking, a disorder of the thought process, is characterized by regular interruptions in the thought stream. It was described by several scholars as a sign of schizophrenia, with few reports describing thought blocking in association with catatonia. In this article, we describe the course of a patient with bipolar I disorder who presented with catatonia and demonstrated thought blocking. Her catatonic symptoms and thought blocking improved with the addition of lorazepam, recurred upon lorazepam discontinuation, and improved with resumption of lorazepam, demonstrating a clear on/off phenomenon. This report highlights the importance of recognizing thought and cognitive manifestations of catatonia, as it can enhance recognition and improve treatment., (Copyright © 2024 Wolters Kluwer Health, Inc.

Symptoms of catatonia include silence, motionlessness, and postural retention. Although it is important to detect and treat catatonia early, before it becomes severe, postoperative cases have inherent risks that hinder diagnosis and treatment. A 60-year-old man with schizophrenia underwent endoscopic/thoracoscopic esophagectomy and was extubated in the operating room. In the intensive care unit (ICU), he had stiffness in the neck, ankles, and knees, catalepsy during passive knee flexion, mild disturbance of consciousness, mild creatine kinase elevation, and respiratory depression. Intravenous diazepam was administered for diagnosis, and the patient's rapid improvement indicated catatonia. He was intubated and started on lorazepam; tapering produced no recurrence of symptoms. The patient was extubated and transferred to the general ward on postoperative Day 2. Because this patient was extubated in the operating room and was managed postoperatively in the ICU with a full-time doctor, his symptoms were easily recognized and early diagnosis was possible. Thus, we were able to administer drug therapy quickly and adequately and perform forward management that accounted for postoperative risks, thereby achieving a favorable outcome.

Neuroleptic malignant syndrome (NMS) is a severe adverse reaction associated with neuroleptic or antipsychotic drugs. This case report discusses a 43-year-old man with a history of bipolar disorder and polysubstance abuse who presented with altered mental status, autonomic dysfunction, and muscular rigidity. The patient had recently started on ziprasidone, a second-generation antipsychotic, leading to an atypical presentation of NMS. Unlike classic findings associated with NMS induced by first-generation antipsychotics, this case lacked high fever, lead pipe rigidity, or elevated creatine kinase levels greater than 1000 on initial presentation. The delay in diagnosis was attributed to the milder symptoms and absence of typical findings, resulting in extensive diagnostic workup and interventions. The patient responded positively to treatment with lorazepam based on the Woodbury severity stage guidelines. This case underscores the complexity of diagnosing NMS induced by second-generation antipsychotics and highlights the need for awareness and tailored treatment approaches for atypical presentations., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The effect of lorazepam in the treatment of catatonia is outstanding and almost immediate. Clinicians are familiar with its effects: mute patients can speak again, akinetic patients can move again and patients with negativism can eat and drink again within usually a short duration of about 10 min to 1-2 h. Fear is often gone after lorazepam administration. While not always effective, the introduction of lorazepam into clinical practice represented a breakthrough and was often life-saving for many patients suffering from catatonia. It is rare to observe such rapid therapeutic effects in other domains of psychiatry. In this narrative review we will briefly look at the past, present and future of lorazepam in the treatment of catatonia. It is gratifying to reflect on the fact that clinicians using the age-old medical practice of observation and empirical treatment succeeded in advancing the management of catatonia 40 years ago. The present evidence shows that the clinical effect of lorazepam in catatonia treatment is excellent and more or less immediate although it remains to be explicitly tested against other substances such as diazepam, zolpidem, clozapine, quetiapine, amantadine, memantine, valproate and dantrolene in randomized clinical trials. In addition, future studies need to answer the question how long lorazepam should be given to patients with catatonia, months or even years? This narrative review promotes the rapid use of lorazepam in the treatment of acute catatonic patients and stipulates further scientific examination of its often impressive clinical effects., Competing Interests: Declaration of competing interest The authors have declared that there are no conflicts of interest in relation to the subject of this study., (Copyright © 2023 Elsevier B.V.

Given the rising frequency of drug shortages in hospitals, interdisciplinary collaboration is necessary to manage medications, modify electronic medical records, and evaluate safety outcomes. One such shortage impacted lorazepam injection, a medication commonly used in palliative care to treat anxiety, agitation, and seizures. In anticipation of the lorazepam shortage in the summer of 2022, pharmacy staff collaborated with palliative care physicians to identify alternative treatment recommendations when providers were prohibited from ordering lorazepam injection. Before the shortage, lorazepam was used an average of 95 times per month on the palliative care unit. The overall use of benzodiazepines decreased substantially following the recommendation for the therapeutic alternative, midazolam, during the shortage. Once the shortage ended, use roughly returned to pre-shortage baselines. During this time, there were no patient safety events documented on the palliative care unit. Moreover, no changes to the care experience were reported by patients, family/caregivers, providers, or staff. The collaborative effort between pharmacy and palliative care specialists resulted in alternative treatments for palliative care patients during the drug shortage. This preserved the hospital's supply of lorazepam injection for a patient population with no suitable alternatives while still allowing for management of palliative patients.

Benzodiazepines are commonly used medications which are clinically useful towards the treatment of alcohol withdrawal, seizures, anxiety disorders, among other indications. Benzodiazepine use is also known to cause the rare phenomenon of paradoxical excitation whose mechanism has many postulated theories. We report this rare presentation of paradoxical excitation with the use of lorazepam in a 50-year-old male being treated for alcohol withdrawal. We also review the underlying pathophysiology, pharmacology, and current literature as it relates to this excitation. An inability to recognize this adverse effect and to appropriately withhold the agent may adversely affect a patient's course of treatment in the inpatient setting.

Introduction: Nonopioid-based strategies for managing chronic noncancer pain are needed to help reduce overdose deaths. Although lab studies and population-level data suggest that cannabinoids could provide opioid-sparing effects, among medical cannabis participants they may also impact overdose risk by modifying other controlled substance use such as sedative hypnotics. However, no study has combined observational data at the individual level to empirically address interactions between the use of cannabinoids and prescribed controlled substances. Methods: Electronic health records, including prescription drug monitoring program data, from a large multisite medical cannabis program in New York State were abstracted for all participants with noncancer pain and recently prescribed noncannabinoid controlled substances who completed a new intake visit from April 15, 2018-April 14, 2019 and who remained actively in treatment for >180 days. Participants were partitioned into two samples: those with recent opioid use and those with active opioid use and co-use of sedative hypnotics. A patient-month level analysis assessed total average equivalent milligrams by class of drug (i.e., cannabinoid distinguishing tetrahydrocannabinol [THC] vs. cannabidiol [CBD], opioids, and sedative-hypnotics) received as a time-varying outcome measure across each 30-day "month" period postintake for at least 6 months for all participants. Results: Sample 1 of 285 opioid users were 61.1 years of age (±13.5), 57.5% female, and using an average of 49.7 (±98.5) morphine equivalents daily at intake. Unadjusted analyses found a modest decline in morphine equivalents to 43.9 mg (±94.1 mg) from 49.7 (±98.5) in month 1 ( p =0.047) while receiving relatively low doses of THC (2.93 mg/day) and CBD (2.15 mg/day). Sample 2 of 95 opioid and sedative-hypnotic users were 60.9 years of age (±13.1), 63.2% female, and using an average of 86.6 (±136.2) morphine equivalents daily, and an average of 4.3 (±5.6) lorazepam equivalents. Unadjusted analyses did not find significant changes in either morphine equivalents ( p =0.81) or lorazepam equivalents ( p =0.980), and patients similarly received relatively low doses of THC (2.32 mg/day) and CBD (2.24 mg/day). Conclusions: Findings demonstrated minimal to no change in either opioids or sedative hypnotics over the 6 months of medical cannabis use but may be limited by low retention rates, external generalizability, and an inability to account for nonprescribed substance use.

Background and Objectives: Antiseizure medications (ASMs) are among the most commonly prescribed teratogenic drugs in women of childbearing age. Limited data exist on utilization patterns across different indications for therapy and for the newer-generation ASMs in this population. Thus, we assessed the pattern of ASM use in women of childbearing age with epilepsy and nonepilepsy indications (pain and psychiatric disorders)., Methods: We conducted a retrospective analysis of deidentified administrative data submitted to the Optum Clinformatics database. Eligible participants included women aged 12-50 years who filled ASMs between year 2011 and 2017. Participants were followed from date of index prescription filled to study end or insurance disenrollment, whichever came first. For the overall cohort and potential therapy indications, we assessed the type and frequency of ASMs filled; proportion of participants on monotherapy, polytherapy, or treatment switching; and duration of continuous use. Trends were characterized using annual percent change from study start to study end., Results: Our analysis included 465,131 participants who filled 603,916 distinct ASM prescriptions. At baseline, most of the participants had chronic pain (51.0%) and psychiatric disorders (32.7%), with epilepsy the least common (0.9%). The most frequently dispensed were diazepam (24.3%), lorazepam (20.1%), gabapentin (17.4%), clonazepam (12.7%), topiramate (11.3%), and lamotrigine (4.6%). Significant linear increase in trends were observed with gabapentin (annual percent change [95% CI]: 8.4 [7.3-9.4]; p < 0.001) and levetiracetam (3.4 [0.7-6.2]; p = 0.022) and decreasing trends for diazepam (-3.5 [-2.4 to 4.5]; p < 0.001) and clonazepam (-3.4 [-2.3 to 4.5]; p = 0.001). No significant change in trend was observed with valproate (-0.4 [-2.7 to 1.9]; p = 0.651), while nonlinear changes in trends were observed with lorazepam, topiramate, lamotrigine, and pregabalin., Discussion: Decreasing trends were observed with older ASMs in the overall cohort and across the potential indications for therapy. Conversely, increasing trends were seen with the newer ASMs. Considering the risk of teratogenicity associated with the newer medications largely unknown, counseling and education in addition to a careful consideration of the benefits vs potential risks should remain pivotal when prescribing ASMs for women of childbearing age., (© 2023 American Academy of Neurology.)

Cannabinoid hyperemesis syndrome (CHS), an under-recognized and seemingly paradoxical condition, arises in some adolescents and adults who chronically use cannabis. It presents acutely with intractable nausea, vomiting, and abdominal pain but standard antiemetic therapy leads to improvement for only a minority of patients. Randomized controlled trial evidence in adults indicates the superiority of haloperidol over ondansetron in alleviating the acute symptoms of CHS, but safe and effective treatment for adolescents with the disorder is currently unknown. The successful use of topical capsaicin has also been reported. We report a case series of 6 adolescent patients with CHS who presented to Johns Hopkins All Children's Hospital and were treated with haloperidol, lorazepam, and/or capsaicin. Four patients given 5 mg intravenous (IV) haloperidol and 2 mg IV lorazepam and 1 patient treated with 5 mg IV haloperidol and peri-umbilical topical capsaicin (0.025%) experienced full acute symptomatic relief. One patient, treated only with topical capsaicin, reported improvement of symptoms with some persistent nausea. Haloperidol/lorazepam, haloperidol/capsaicin, and topical capsaicin alone appear safe and effective in adolescents, but larger studies are required to confirm our findings., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Objective: Limited acute home treatments are available for patients with prolonged (>5 minutes) or repetitive (≥2 in 24 hours) seizures. While this early seizure treatment may reduce the need for emergency care, intermittent intranasal benzodiazepine formulations are expensive and rectal diazepam administration is often socially unacceptable. We determined whether caregivers could use sublingual lorazepam oral concentrate solution effectively as acute treatment for adults with prolonged and repetitive seizures., Methods: Patients prescribed sublingual lorazepam solution at the Johns Hopkins Epilepsy Center for acute seizure treatment during a 5-year period (2012-2017) were screened. We determined clinical history of seizure patterns and number of antiseizure medications (ASMs) through patient and caregiver surveys, and we verified this history in patients' medical records and charts. During a 2-year span (2017-2018), patients and caregivers were surveyed on responses to their most recent use of sublingual lorazepam solution, including seizure cessation (prolonged seizure stopping <5 minutes or ≤1 repetitive seizure), presence of sedation and adverse events within 24 hours of administration, and whether refrigeration limited use., Results: In total, 52 patients used sublingual lorazepam for treatment of acute seizures during the study period (median dose 1 mg, range 0.5 to 2 mg). Of them, 48 patients participated in treatment survey interviews. Family caregivers usually administered lorazepam (88%); 3 self-administered. Patients were surveyed on responses to their most recent use of sublingual lorazepam treatment: 66% (23/35) of patients with repetitive seizures reported no further seizure activity after administering treatment; 70% (7/10) with prolonged seizures reported seizure activity ceased within 5 minutes of treatment. Three patients treated auras and had no seizures. There were no serious adverse events during most recent use: 31% of patients developed moderate/severe sedation. Of note, 98% refrigerated lorazepam, often with coolers; 44%, however, said this limited treatment access. There was high treatment satisfaction; 79% reported that having the emergency treatment available made them feel safer., Significance: This patient survey and retrospective chart review demonstrates that home treatment with sublingual lorazepam solution may be effective for interrupting prolonged and repetitive seizures. No patients had sedation complications with home doses of 0.5 to 2 mg, and patients report high satisfaction with the treatment., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Gregory L.

Catatonia is a psycho-motor disorder associated with various psychiatric, neurological, and medical illnesses. It is due to alteration in GABAergic circuits and basal ganglia. Management includes identifying the underlying cause and handling complications with supportive treatment. It can cause life-threatening complications like dehydration and cardiac arrest. The risks are more in children and adolescent populations. Benzodiazepines and electro-convulsive therapy are treatment modalities. In this case report we discuss about a child who was resistant to both lorazepam and electroconvulsive therapy. Resistance to both first-line management is a rare phenomenon. We were able to manage with a combination of antipsychotics and antidepressants. Catatonia in children may respond late to treatment. Symptomatic treatment, ruling out organic causes, and judicious use of pharmacotherapy can be beneficial in resistant cases., Keywords: benzodiazepines; case reports; catatonia; electroconvulsive therapy.

Background: Emerging literature supports the association between acute COVID-19 infection and neuropsychiatric complications. This article reviews the evidence for catatonia as a potential neuropsychiatric sequela of COVID-19 infection., Methods: PubMed was searched using the terms catatonia, severe acute respiratory syndrome coronavirus 2, and COVID-19. Articles were limited to those published in the English language between 2020 and 2022. Forty-five articles that specifically studied catatonia associated with acute COVID-19 infection were screened., Results: Overall, 30% of patients with severe COVID-19 infection developed psychiatric symptoms. We found 41 cases of COVID-19 and catatonia, with clinical presentations that varied in onset, duration, and severity. One death was reported in a case of catatonia. Cases were reported in patients with and without a known psychiatric history. Lorazepam was successfully used, along with electroconvulsive therapy, antipsychotics, and other treatments., Conclusions: Greater recognition and treatment of catatonia in individuals with COVID-19 infection is warranted. Clinicians should be familiar with recognizing catatonia as a potential outcome of COVID-19 infection. Early detection and appropriate treatment are likely to lead to better outcomes.

Introduction: Individuals with profound autism often present for inpatient care due to aggression. Diagnostic and treatment options are limited. Agitated catatonia is a treatable comorbidity in autism, which should be considered in cases of aggression. Preliminary data report high clinical response rates of catatonia in autism when treated with electroconvulsive therapy (ECT), with poor response to lorazepam. However, access to ECT is often limited, especially in pediatric populations. Methods: We conducted a retrospective chart review to identify cases of hyperactive catatonia with partial response to lorazepam in profoundly autistic children presenting to the pediatric medical hospital. Five cases were identified, all of whom were followed by the child and adolescent psychiatry consult-liaison service during admission and treated without the use of ECT. Data from the medical record were obtained after institutional review board (IRB) approval including the following: (1) treatment course, (2) Bush-Francis Catatonia Rating Scale (BFCRS) scores, and (3) Kanner Catatonia Rating Scale (KCRS) severity scores. The Clinical Global Impressions-Improvement (CGI-I) Scale was applied retrospectively to each case. Results: All five patients demonstrated clinically significant improvements. The average CGI-I score was 1.2. The average percentage reduction in the BFCRS and KCRS severity scores was 63% and 59%, respectively. Two of five patients were first stabilized with infusions midazolam and dexmedetomidine due to the symptom severity and then transitioned to long-acting oral benzodiazepines. Overall, four of five patients were stabilized with oral clonazepam and one of five with oral diazepam. Notably, four of five patients experienced an acute worsening of aggression, self-injury, and other catatonic symptoms with escalating dosages of antipsychotic treatment, which occurred before inpatient admission. All patients experienced resolution of physical aggression toward self and/or others, experienced improvement in their communicative abilities, and were able to return home or enter residential level of care upon discharge. Conclusions: Given the limited availability of ECT and the unclear utility of lorazepam for hyperactive catatonia in autism, the use of long-acting benzodiazepines and/or midazolam infusion may offer a safe and readily available treatment alternative.

Background: Catatonia is a complex neuropsychiatric syndrome that can be associated with several underlying etiologies including primary psychiatric and autoimmune disorders. Anti-N-methyl-D-aspartate receptor encephalitis is an autoimmune disorder typically characterized by seizures, movement abnormalities, and behavioral changes. Anti-N-methyl-D-aspartate can present with complex neuropsychiatric symptoms including catatonia which can be challenging for clinicians to identify as excited catatonia can mimic delirium and psychiatric disorders such as psychosis and mania., Objectives: To identify and present cases of anti-N-methyl-D-aspartate receptor encephalitis where excited catatonia is the presenting symptom., Methods: We present 2 case studies of agitation and disinhibition in an adolescent and young adult that were ultimately found to be secondary to autoimmune receptor encephalitis, in both cases, confirmed by cerebrospinal fluid analysis to be due to anti-N-methyl-D-aspartate receptor antibodies., Results: Excited catatonia was suspected and initially treated with immunological therapy and high doses of lorazepam. As the severity of catatonia progressed with limited improvement with lorazepam, both cases were ultimately effectively treated with electroconvulsive therapy., Conclusions: Excited catatonia should be considered with presentations of bizarre behavior, agitation, disinhibition, and other psychotic symptoms in patients with no prior psychiatric history. Although the primary treatment for catatonia associated with anti-N-methyl-D-aspartate receptor encephalitis is immunomodulatory therapy paired with benzodiazepines, electroconvulsive therapy has been shown to be an effective and safe adjuvant treatment that is especially useful for management of excited catatonia., (Copyright © 2022 Academy of Consultation-Liaison Psychiatry.

BACKGROUND: In spaceflight, acute urinary retention (AUR) could develop as a sequela of medication use, urinary tract infection, urolithiasis, or intentional urine holding. While AUR is generally treated with bladder decompression, urinary catheterization could be difficult operationally in terms of training and proficiency, supplies, and lack of space or privacy. This report discusses a case in which tamsulosin and lorazepam were used successfully on an offshore ship while awaiting medical evacuation, a situation that could arise in remote locations where aerospace operations are conducted. CASE REPORT: A 52-yr-old man with hypertension and obstructive sleep apnea but no formal diagnosis of benign prostatic hyperplasia was unable to urinate for over 16 h while on a deep-sea fishing vessel approximately 200 nmi offshore. By phone, the physician providing remote medical direction diagnosed AUR in the setting of possible infection and prescribed acetaminophen, ciprofloxacin, and a trial of tamsulosin as the ship did not have any medical personnel trained to perform urinary catheterization and there were no catheter supplies available. Lorazepam was later added for anxiolysis and potential smooth muscle relaxation. Within 1 h of initial medication administration, the patient successfully voided a large quantity of urine, which tested positive for infection by urine dipstick. The patient was continued on antibiotics and evacuated to a medical facility onshore for further management. DISCUSSION: Pharmacological treatment could be considered as a temporizing measure where operational constraints limit the ability to perform urinary catheterization to relieve acute urinary retention.

Introduction: Status epilepticus (SE) is a neurological emergency associated with high mortality if not identified and treated promptly. For the emergent treatment of SE, the recommended intravenous (IV) lorazepam dose is 0.1 mg/kg/dose, up to a maximum of 4 mg. It has been shown that lorazepam is commonly under dosed in SE, but there is conflicting data on whether this has a negative impact on patient outcomes. This study assessed any dose less than 4 mg to help identify the effects of under dosing lorazepam in SE., Methods: This was a retrospective cohort study of patients admitted to a quaternary health system between October 1, 2017 and September 30, 2019 that experienced SE and were initially treated with IV lorazepam. Patients were divided into two cohorts, less than 4 mg or 4 mg, based on the initial one-time dose of lorazepam received. The primary outcome was the proportion of patients that progressed to refractory status epilepticus (RSE) that received an initial IV lorazepam dose of 4 mg compared to less than 4 mg for the treatment of SE. Secondary outcomes evaluated include length of stay, mortality, time in SE, number of seizures, cumulative lorazepam dose prior to urgent therapy, number of lorazepam doses prior to urgent therapy, time to urgent therapy, appropriately dosed urgent therapy, and number of antiepileptic drugs given in SE., Results: One hundred twenty patients were included in this study (107 patients received less than 4 mg and 13 patients received 4 mg). All patients included in the study were greater than 40 kg. The primary outcome of progression to RSE was observed in a significantly greater proportion of patients in the less than 4 mg group compared to the 4 mg group (93 [87%] vs. 8 [62%], p = 0.03). There was no difference in hospital or intensive care unit length of stay. However, there was an increased rate of in-hospital mortality in patients who received 4 mg compared to less than 4 mg (5 [39%] vs. 12[11%], p = 0.02)., Discussion: The majority of patients in the study received less than the recommended dose of IV lorazepam for SE. Patients who received less than 4 mg experienced an increased progression to RSE, which supports current guideline recommended dosing. While there was an increased rate of mortality in patients who received 4 mg compared to less than 4 mg, time in SE was prolonged in the patient population and severity of illness was only available for a limited number of patients included., (Copyright © 2023 Elsevier B.V.

Background: Despite frequent benzodiazepine use in anxiety disorders, the trajectory and magnitude of benzodiazepine response and the effects of benzodiazepine potency, lipophilicity, and dose on improvement are unknown., Methods: We performed a meta-analysis using weekly symptom severity data from randomized, parallel group, placebo-controlled trials of benzodiazepines in adults with anxiety disorders. Response was modeled for the standardized change in continuous measures of anxiety using a Bayesian hierarchical model. Change in anxiety was evaluated as a function of medication, disorder, time, potency, lipophilicity, and standardized dose and compared among benzodiazepines., Results: Data from 65 trials (73 arms, 7 medications, 7110 patients) were included. In the logarithmic model of response, treatment effects emerged within 1 week of beginning treatment (standardized benzodiazepine-placebo difference = -0.235 ± 0.024, CrI: -0.283 to -0.186, P < .001) and placebo response plateaued at week 4. Doses <6 mg per day (lorazepam equivalents) produced faster and larger improvement than higher doses ( P = .039 for low vs medium dose and P = .005 for high vs medium dose) and less lipophilic benzodiazepines (beta = 0.028 ± 0.013, P = .030) produced a greater response over time. Relative to the reference benzodiazepine (lorazepam), clonazepam (beta = -0.217 ± 0.95, P = .021) had a greater trajectory/magnitude of response (other specific benzodiazepines did not statistically differ from lorazepam)., Conclusions: In adults with anxiety disorders, benzodiazepine-related improvement emerges early, and the trajectory and magnitude of improvement is related to dose and lipophilicity. Lower doses and less lipophilic benzodiazepines produce greater improvement.

Background: Catatonia is a cluster of motor features present in multiple psychiatric and clinical diseases. It may be confused with delirium because both entities are classified according to the type and degree of psychomotor activity. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria for catatonia secondary to medical conditions exclude comorbid catatonia and delirium; besides, there have been increasing reports about a comorbid presentation. This study aimed to describe the prevalence of comorbid catatonia and delirium, the therapeutic response to lorazepam, and the clinical characteristics of patients with an earlier diagnosis of delirium., Methods: A total of 120 consecutive patients at a university hospital with an earlier diagnosis of delirium were evaluated using the Delirium Scale (confusion assessment method for the intensive care unit) and the Bush-Francis Catatonia Rating Scale for catatonia. In cases of a positive diagnosis of catatonia or catatonia/delirium, a therapeutic trial with intramuscular lorazepam was performed., Findings: Thirty-one patients (26%) were positive for both catatonia and delirium, and 8 patients (7%) had catatonia. Sixty-six patients (55%) were positive only for delirium, and 5 patients (4%) were negative for delirium and catatonia. Lorazepam tests were applied on 22 patients. One in 9 patients with catatonia/delirium responded positively to lorazepam. Patients with catatonia had a 60% positive response rate., Conclusions: This is the first study on lorazepam use in catatonia-delirium patients; however, further studies are needed to determine the safety and efficacy of lorazepam in these patients. Catatonia and catatonia/delirium are underdiagnosed in inpatient wards and should be routinely assessed in patients with an altered mental status., (Copyright © 2022 Wolters Kluwer Health, Inc.

Catatonia can be associated with multiple physical and mental illnesses, and idiopathic catatonia is a well-recognized clinical entity. Here we report a case of recurrent idiopathic catatonia with underlying immunologic abnormalities, with an emphasis on etiological hypotheses. An 18-year-old female with mild learning disability, dyspraxia, autoimmune hypothyroidism, and nonceliac gluten intolerance was referred to mental health services after developing an episode of catatonia following tonsillitis. She had experienced 2 previous episodes suggestive of catatonia, one of which developed after a snakebite and the other after a viral infection. Samples of cerebrospinal fluid and whole blood tested positive for human herpesvirus (HHV) on DNA-polymerase chain reaction testing during her third episode, but the patient had no signs of encephalitis. She responded well to lorazepam but developed significant side effects with low-dose olanzapine and aripiprazole. She returned to her usual baseline with medical management. Very little is known about possible etiologies of recurrent idiopathic catatonia. An atypical response to an HHV infection is a likely cause of one of the episodes in this case. There is substantial evidence connecting immune dysregulation to mental illnesses. Proinflammatory effects of latent HHV, proinflammatory genetic polymorphisms related to learning disability, and autoimmune dysfunction are likely factors that may have contributed to the development of recurrent catatonia following external antigen exposure in this case. Future research should focus on immune-mediated etiologies of catatonia, the role of immunotherapy in the treatment of idiopathic catatonia, and systems research to improve multidisciplinary management of neuropsychiatric disorders., Competing Interests: A.D. has a biological relationship with the patient in the reported case. This author was not involved in the clinical care of the patient, but was involved in the preparation of this manuscript.

Introduction: This project aimed to retrospectively obtain, review, and extract key safety data from medical records of participants enrolled in RAMPART, the NIH-supported Rapid Anticonvulsant Medication Prior to ARrival Trial of intramuscular midazolam versus intravenous lorazepam for pre-hospital treatment of status epilepticus, to support a US new drug application (NDA) for intramuscular midazolam., Methods: A collaborative partnership was established between the NDA sponsor, the RAMPART trial lead academic institution, US government agencies, and contract research organizations to retrieve, review, and extract relevant safety data from the medical records of RAMPART participants and summarize those data to include in an NDA submitted to the US Food and Drug Administration (FDA)., Results: Key data in the medical records of 890 RAMPART trial participants (1020 enrollments, including 130 repeat enrollments) were reviewed and extracted into a project database. Safety events occurred in 771 (86.6%) participants, and included additional information not collected in the RAMPART trial. This database also enabled subgroup analyses based on medical history and prior/concurrent medications, building upon previous analyses according to age, sex, and race. No previously unrecognized safety patterns were identified, and no association was observed between efficacy and medical history or medication usage., Conclusions: The use of unstructured real-world retrospective medical record data can effectively support an NDA submission in place of conducting another interventional clinical trial. This retrospective medical records review and extraction of additional safety data contributed to the FDA approval of intramuscular midazolam for the pre-hospital treatment of status epilepticus in 2018., Clinicaltrials: GOV: NCT00809146., (© 2022.
