Generalized tetanus is still a global concern with a mortality rate of up to 50%, especially in low and middle-income countries. We reported a 23-year-old man from Afghanistan admitted to emergency department, with the chief complaint of generalized severe spasms and lockjaw. The patient had skin lesions and had never been vaccinated against tetanus.

Background: Different virulence factors are involved in the pathogenesis of urinary tract infection (UTI) caused by Uropathogenic (UPEC); hence, this study aimed to study the prevalence of biofilm formation, virulence factors, and phylogenetic groups and their correlation with biofilm formation among UPEC isolates through a systematic review and meta-analysis.

Materials And Methods: A literature search was conducted from 1, 2000, to the end of 2021 in different databases for studies that reported biofilm together with virulence genes or phylogenetic groups in UPEC isolates from patients with UTI according to PRISMA protocol. Data were analyzed by Comprehensive meta-analysis software.

Background: Iran was one of the first countries to become an epicenter of the coronavirus disease 2019 (COVID-19) epidemic. However, there is a dearth of data on the outcomes of COVID-19 and predictors of death in intensive care units (ICUs) in Iran. We collected extensive data from patients admitted to the ICUs of the one of the tertiary referral hospitals in Tehran, Iran, to investigate the predictors of ICU mortality.

Background: Keeping the heart rate within the normal range has improved the survival of septic shock patients. Amiodarone could target the underlying pathophysiology of sepsis-induced tachycardia. This study aimed to determine whether amiodarone is effective in controlling the heart rate in critically ill patients with septic shock and sustained tachycardia who were receiving vasopressor.

Background: The pathophysiology of cardiac arrest (CA) involves over-activation of systemic inflammatory responses, relative adrenal insufficiency, and glycocalyx damage. Corticosteroids have beneficial effects in preventing the perturbation of the endothelial glycocalyx.

Objectives: The aim of this systematic review was to determine the efficacy of glucocorticoids in patients with cardiac arrest.

Spinal cord injury is a devastating chronic condition resulting in temporary or permanent motor, sensory or autonomic dysfunction of the cord. The manifestation of spinal cord injury based on the severity and involved areas could be different. Numerous studies have demonstrated that bradycardia, hypotension, and orthostatic hypotension are present insignificant number of patients after spinal cord injury which peaks at 4 day of injury.

Introduction: Classically, aminoglycosides are known to have low penetration into the lung tissue. So far, no study has been conducted on human adult patients to evaluate amikacin concentration in epithelial lining fluid (ELF) of the alveoli. Therefore, convincing data are not available from the perspective of pharmacokinetics to support the fact that a dosage of 20 mg/kg of amikacin is sufficient to treat patients with ventilator-associated pneumonia (VAP).

Objective: Although mechanical ventilation is frequently a life-saving therapy, its use can result in unwanted side effects. It has been well documented that the choice of sedating agent may influence the duration of mechanical ventilation. Melatonin is a sedative and analgesic agent without any respiratory depressant effect which makes it an attractive adjuvant for sedation in the intubated patients.
