Objective: To measure the effect of doxycycline on inflammatory marker [IL-6, TNF-α, ferritin and C reactive protein (CRP)] levels in patients with dengue infection. Methods: A single-centre, open-label, parallel-group randomized controlled trial was done in PGIMER Chandigarh from June 2021 to October 2022. Patients were randomized using a simple randomization process into two groups: the doxycycline treatment group (n=35) and the control group (n=34). Patients in the treatment group were given oral doxycycline 100 mg twice daily for five days along with standard treatment, whereas patients in the control group received only standard treatment. The objective was to measure the effect of doxycycline on inflammatory markers in dengue infection. Results: On comparative analysis at day 5, there was a statistically significant reduction in the median values of ferritin and CRP in cases compared to the control group (ferritin: P=0.006 and CRP: P=0.006). No significant reduction was noted in the levels of IL-6 and TNF-α. Conclusions: Doxycycline treatment led to a reduction of inflammatory markers in dengue infection. [ABSTRACT FROM AUTHOR]

Introduction Despite the widespread use of antivenom for the treatment of snakebite envenoming in the Indian subcontinent, the ideal dose of antivenom has been a point of contention. Low-dose regimens can economize on a scarce resource in low- and middle-income countries. This study assessed the effectiveness of a low-dose (10 vials) antivenom regimen compared to the usual 20 vials in patients with krait bite neuroparalysis requiring mechanical ventilation. Methods This study was a prospective controlled pilot study conducted in a tertiary-care hospital in north India. Participants were eligible if they were ≥12 years old, had krait bite neurotoxicity, showed severe paralysis requiring mechanical ventilation, and had access to antivenom therapy within 24 h of the bite. The primary outcome was the duration of mechanical ventilation, and the secondary outcomes were the length of hospital stay and in-hospital survival. Results Fifteen patients received 10 vials of antivenom, and 25 received 20 vials. The two treatment groups had similar baseline demographics, clinical and laboratory features, snakebite severity scores, and median time from snakebite to initiation of antivenom therapy. The low-dose regimen was as effective as the standard dose concerning the median duration of mechanical ventilation (41 h vs. 55 h, P  = 0.094), the median length of stay (78 h vs. 85.5 h, P  = 0.360), and in-hospital deaths (1 vs. 3, P  = 1.000). The incidence of ventilator-associated pneumonia was similar between the two groups (1 vs 3, P  = 1.000). Conclusion A low dose of antivenom effectively treats patients with severe krait bite neuroparalysis. [ABSTRACT FROM AUTHOR]

Honeybee stings with features of envenomation (either local or allergic and rarely systemic toxicity) are often seen in agriculture workers. An initial presentation with severe diffuse alveolar hemorrhage or pulmonary-renal syndrome is rare and only confined to a few case reports. Herein, we describe a case of a 45-year-old male who presented with multiple bee stings and subsequently developed acute kidney injury and pulmonary hemorrhage. He was managed with hemodialysis, invasive mechanical ventilation, red-cell transfusion, and pulse methylprednisolone. However, he developed cardiac arrhythmias with ventricular tachycardia and died.

Circulatory shock is a common condition that carries high morbidity and mortality. This review aims to update the critical steps in managing common types of shock in adult patients admitted to medical emergency and intensive care units. A literature review was performed by searching PubMed, EMBASE Ovid, and Cochrane Library, using the following search items: ("shock" OR "circulatory shock" OR "septic shock" OR "cardiogenic shock") AND ("management" OR "treatment" OR "resuscitation"). The review emphasizes prompt shock identification with tissue hypoperfusion, knowledge of the underlying pathophysiological mechanism, initial fluid resuscitation with balanced crystalloids, norepinephrine as the preferred vasopressor in septic and profound cardiogenic shock, and tailored intervention addressing specific etiologies. Point-of-care ultrasound may help evaluate an undifferentiated shock and determine fluid responsiveness. The approach to septic shock is improving; however, confirmatory studies are required for many existing (e.g., amount of initial fluids and steroids) and emerging (e.g., angiotensin II) therapies. Knowledge gaps and wide variations persist in managing cardiogenic shock that needs urgent addressing to improve outcomes. [ABSTRACT FROM AUTHOR]

AIM: The principal objective of this study was to carry out a comprehensive and thorough analysis to compare the safety and effectiveness of the Arctic Sun, a servo-controlled surface cooling device, with conventional cooling techniques for providing therapeutic hypothermia in adult patients who had experienced hypoxic-ischemic brain injury following cardiopulmonary resuscitation. METHODS: In order to achieve our goal, we conducted an extensive search of multiple databases including PubMed, Embase, Cochrane, and ClinicalTrials.gov up to the date of July 30, 2021. We only included studies that compared the safety and efficacy of the Arctic Sun surface cooling equipment with standard cooling approaches such as cooling blankets, ice packs, and intravenous cold saline for treating comatose adult patients who had recovered after experiencing cardiac arrest. We evaluated various outcomes, including all-cause mortality, good neurological outcome at 1 month, and the occurrence of adverse effects such as infections, shock, and bleeding. We employed a random-effects meta-analysis to estimate the odds ratio (OR) with 95% confidence intervals (CIs) for dichotomous outcomes. RESULTS: One hundred and fourteen records were identified through our search; however, only three studies met our eligibility criteria, resulting in overall 187 patients incorporated in the meta-analysis. The findings indicated no significant difference in mortality rates among the Arctic Sun device and conventional cooling techniques (OR: 0.64; 95% CI: 0.34-1.19; P = 0.16; I² = 0%). In addition, we found no significant difference in occurrence of good neurological outcomes (OR: 1.74; 95% CI: 0.94-3.25; P = 0.08; I² = 0%) between the two cooling methods. However, the application of the Arctic Sun device was associated with increased incidence of infections compared to standard cooling methods (OR: 2.46; 95% CI: 1.18-5.11; P = 0.02; I² = 0%). While no significant difference occurred in the incidence of shock (OR: 0.29; 95% CI: 0.07-1.18; P = 0.08; I² = 40%), the use of the Arctic Sun device was linked to significantly fewer bleeding complications compared to standard cooling methods (OR: 0.11; 95% CI: 0.02-0.79; P = 0.03; I² = 0%). CONCLUSIONS: After analyzing the results of our meta-analysis, we concluded that the use of the Arctic Sun device for targeted temperature management following cardiopulmonary resuscitation did not result in significant differences in mortality rates or improve neurological outcomes when compared to standard cooling techniques.

OBJECTIVES: The prognosis of acute aluminum phosphide poisoning is usually based on toxidrome features, with little focus on poison-related factors. We aimed to study the prognostic significance of poison-related factors, consumption patterns, and time delays to treatment. METHODS: We performed a prospective cohort study in an academic hospital in North India in patients aged = 13 with aluminum phosphide poisoning from July 2019 to December 2020. During data collection, a particular emphasis was made on the poison formulation, the ingested dose, the reconstitution of poison, vomiting, and time intervals to initiate various treatments. The primary outcome was inhospital mortality. RESULTS: Fifty-eight patients were enrolled (median age, 32 years; 37 males). The mean dose of the ingested poison was 6.56 (±5.42) g. The predominant formulation of poison was pellet (n = 41), followed by powder (n = 16). Twenty patients performed reconstitution of poison before consumption, and 13 stirred the poison while reconstituting. All patients but three developed vomiting after consumption. Inhospital mortality (n = 23, 39%) was significantly high with a higher ingested dose (P < 0.001), nonstirred reconstitution before consumption (P = 0.042), fewer vomiting episodes (P = 0.010), a delay in detection of the victim by someone (P = 0.001), and delayed initiation of intravenous fluids (P = 0.043). The secondary outcomes (shock and requirement of vasopressor or ventilation) remained unaffected by the stirring in the reconstitution group. CONCLUSIONS: Poison-related factors and time intervals determine early risk stratification at admission in aluminum phosphide poisoning. [ABSTRACT FROM AUTHOR]

IgA nephropathy is a renal-limited form of systemic vasculitis, and pulmonary manifestations are uncommon. An initial presentation with severe diffuse alveolar hemorrhage (DAH) or pulmonary-renal syndrome is rare and only confined to a few case reports. Herein, we present a young male admitted with acute-onset dyspnea, hemoptysis, and rapidly progressive renal failure. With an initial diagnosis of an immune-mediated pulmonary-renal syndrome, he was treated with high-dose corticosteroids and therapeutic plasmapheresis along with intensive organ support (including hemodialysis, red cell transfusion, and high-flow oxygen). After a detailed laboratory evaluation and kidney biopsy, IgA nephropathy was diagnosed. The patient continued to worsen with persistent DAH and died. IgA nephropathy-associated severe DAH or pulmonary-renal syndrome is rare but increasingly recognized. The condition is difficult to diagnose early and has no proven disease-targeted therapy.

OBJECTIVES: Evaluating local trends and continued monitoring of patterns of acute poisoning are essential for prompt recognition of the toxidromes, the establishment of immediate treatment facilities (e.g., antidote availability), and effective preventive strategies (e.g., governmental regulation on hazardous substances marketing). We aimed to describe the prevalence of the various types of poisoning and associated case fatality in our academic hospital in North India. METHODS: A prospective observational descriptive study was conducted, enrolling patients aged ≥13 years with acute poisoning for 17 months from December 2016 to December 2017 and from September 2019 to December 2019, for a total of 17 months. RESULTS: Four hundred and two patients were enrolled (median age 28 years; 63.2% males). Majority of the acute poisoning cases resulted from ingestion (n = 391, 97.3%) and the primary intention was most commonly self-harm (n = 314, 78.1%). The major types of poisoning were pesticide (n = 264, 65.7%), drug overdose (n = 77, 19.2%), and corrosive ingestion (n = 31, 7.7%). Pesticides included insecticides (n = 146, 36.3%; cholinesterase inhibitors, n = 91), fungicides (n = 76, 18.9%; all aluminum phosphide), herbicides (n = 22, 5.5%; paraquat, n = 19), and rodenticides (n = 20, 5.0%; coumarin-derived substances, n = 12). Benzodiazepines (n = 33) and opioids (n = 25) were frequent causes of drug overdose. 95.3% (n = 379) received preliminary treatment at the previous health-care center, including gastric lavage (n = 239) and antidotes (n = 73). In-hospital case fatality rate was 17.3% (n = 58). CONCLUSION: Herbicide ingestion and opioid overdose are emerging threats with a gradual decline in organophosphate and aluminum phosphide poisoning. Despite improving management of acute poisoning, the overall case fatality rate remains substantial. [ABSTRACT FROM AUTHOR]
