Abstract: We report the case of attempted suicide with amlodipine, chlorthalidone and mefenamic acid and subsequent medical intensive care measures which resulted in total recovery of a 42-year-old male. After admission to the medical intensive care unit the intoxicated patient was deeply hypotensive and needed fluid replacement, dobutamine and norepinephrine. Additionally insulin and calcium gluconate were given. Since hypotension persisted and the patient developed oliguria, terlipressin was applied and finally showed an effect on blood pressure and on urinary output. A volume overload of 7L in the first 24h resulted in a pulmonary edema. The patient was started on non-invasive ventilation with continuous positive airway pressure (CPAP) and frusemide was added to the therapy with good success. Quantitative determination of amlodipine in plasma samples was performed by liquid chromatography–tandem mass spectrometry (LC–MS/MS). The highest amlodipine concentrations was measured in the plasma sample collected approximately 8h after ingestion of the drug, and was 393μg/L. Four days later, it was possible to stop the treatment with catecholamines, at that time the amlodipine plasma concentration had declined to 132μg/L, still tenfold higher than therapeutic (5–18μg/L). Elimination half-life of amlodipine is approximately 55h. After 6 days in the intensive care unit the patient was transferred to psychiatric treatment. Intensive care management and plasma levels in this intoxication case are compared to data from literature on other cases. [Copyright &y& Elsevier]

Context: There is no evidence-based treatment for fatigue in amyotrophic lateral sclerosis (ALS), and identification of treatable causes determines management strategies. Although dyspnea is a key symptom of ALS and effectively treatable, it has not been sufficiently investigated whether dyspnea may be a fatigue-promoting factor.Objectives: To determine the level of fatigue in dyspneic ALS patients and whether fatigue is promoted by dyspnea. We further evaluated the correlation of fatigue with respiratory function tests.Methods: About 101 dyspneic patients and 20 matched controls completed the ALS Functional Rating Scale-Extension and the Fatigue Severity Scale. Dyspneic patients additionally completed the Dyspnea-ALS Scale and the ALS Assessment Questionnaire and underwent respiratory function tests (forced vital capacity, sniff nasal inspiratory pressure, mean inspiratory and expiratory pressure with respective relaxation rates, and blood gases). Multiple regression and correlation analyses were conducted.Results: Dyspneic patients had significantly higher fatigue scores than nondyspneic patients, and their fatigue significantly affected quality of life. Dyspnea alone explained up to 24% of the variance in fatigue. No associations were observed between fatigue and respiratory function tests. Patients with noninvasive ventilation reported significantly more dyspnea and fatigue.Conclusion: Fatigue is a frequent and bothersome symptom in dyspneic ALS patients. Dyspnea-related distress is, in contrast to objective indicators of respiratory impairment, a determining factor of experienced fatigue. There is an urgent need for further symptom relief beyond noninvasive ventilation. Adequate treatment of dyspnea has the potential for synergies in symptom management arising from the association between fatigue and dyspnea. [ABSTRACT FROM AUTHOR]- Published

Context: Dyspnea is a cardinal but often underestimated symptom in amyotrophic lateral sclerosis (ALS). The lack of a satisfying assessment tool leads to diagnostic uncertainty and bears the risk that established life-prolonging and symptom-relieving therapeutic options will not be adequately applied.Objectives: The objective of this study was to develop and validate a German language disease-specific patient-reported outcome measure to assess dyspnea in ALS by combination of a qualitative and quantitative approach using Rasch analysis.Methods: Based on input from clinical experts and patients, a preliminary 35-item questionnaire was developed and completed by 94 patients with ALS having dyspnea. Data were subjected to Rasch analysis and tested for required measurement issues such as appropriate response categories, the absence of differential item functioning, local independence, and unidimensionality.Results: After iterative Rasch analyses, the final 15-item Dyspnea-ALS-Scale (DALS-15) was obtained. The scale satisfies the axioms of the Rasch model with good fit statistics, the absence of local dependency, and differential item functioning as well as acceptable unidimensionality. The DALS-15 is optimally targeted and suitable for group and individual use. It shows excellent test-retest reliability and convergent validity.Conclusion: The DALS-15 satisfies strictest modern measurement criteria and has interval scale properties. It fills an important gap in assessment and could be most helpful to optimize symptom management in patients with ALS. [ABSTRACT FROM AUTHOR]- Published

This case involves a 20-year-old man with prior hallucinogen-use experience, who sniffed an unknown amount of dipropyltryptamine in an apartment. Dipropyltryptamine, a hallucinogenic compound belonging to the tryptamine class is recognized for inducing effects similar to dimethyltryptamine (DMT) but with a longer duration. Ten to fifteen minutes later he experienced visual hallucinations, followed by increasing apathy. Two hours post consumption he developed abdominal pain, leading to collapse, seizure, and vomiting. Despite emergency medical resuscitation on site, transport to hospital 2.5 hours post consumption and extracorporeal life support he died 21 hours later. Relevant toxicological and morphological findings are presented. A serum sample was collected four hours post consumption. Autopsy was performed six days after death. Antemortem serum, as well as postmortem cardiac blood and urine were analyzed for alcohol and psychoactive drugs by systematic toxicological analyses employing gas chromatography-mass spectrometry (Maurer/Pfleger/Weber library among others), liquid chromatography-ion trap mass spectrometry (LC-MSn, Toxtyper™), and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Dipropyltryptamine was quantified by LC-MS/MS after solid-phase extraction. Autopsy revealed a state after deep aspiration of gastric contents with consecutive brain edema due to oxygen deprivation. Dipropyltryptamine concentrations were approximately 210 ng/ml, 110 ng/ml and 180 ng/ml in antemortem serum, postmortem cardiac blood and urine, respectively. To the best of our knowledge, these are the first reported concentrations of dipropyltryptamine in a fatal case. Unlike typical tryptamine overdose reports, this case did not present with agitation, hyperthermia, or tachycardia. Despite the individual's prior experience with tryptamines and the generally low toxicity associated with this class of hallucinogens, death in this case was an indirect consequence of the nasal consumption of a high dose of dipropyltryptamine. • Symptoms and course of fatal dipropyltryptamine intoxication. • Concentrations of dipropyltryptamine in antemortem and postmortem matrices. • Death by aspiration as an indirect consequence of consumption.

Suicides by self-poisoning are common in all parts of the world. Among these intoxications, gases are rarely used, especially carbon dioxide (CO2). Very few cases of self-inflicted and deliberate carbon dioxide poisonings have been reported. This paper presents two uncommon suicides by carbon dioxide intoxication. In one case, a 53-year-old man tightly sealed a small bathroom and locked himself in it likely with dry ice. Warning notices were tagged to the door. In another case, a 48-year-old man working in a restaurant committed suicide by closing himself in a walk-in refrigerator and opening the stored carbon dioxide containers intended for the beverage dispensing equipment. The limited possibilities of proving lethal CO2 intoxications post-mortem necessitate a close cooperation of the involved parties during investigation. Only the synopsis of all findings permits a sound assessment regarding the manner and cause of death. [ABSTRACT FROM AUTHOR]

- Abstract
Abstract: Apart from collisions with road or rail vehicles and falls from height, self inflicted blunt force is a rare suicide method and mainly seen in psychiatric patients. The paper presents a rare case of suicide by active blunt force. A 68-year-old man committed suicide by repeatedly hitting his head with a stone. He sustained a craniocerebral trauma and finally died from hypothermia due to the low outdoor temperature. According to the relatives, the man was not diagnosed with a mental disorder or suicidal tendencies. Uncommon manners of self-harm are challenging for those involved in the investigation, and a differentiation between suicide, accident and homicide can only be made in synopsis of all findings.
