Background: Considerable evidence suggests that smell dysfunction is common in Coronavirus Disease 2019 (COVID-19). Unfortunately, extant data on prevalence and reversibility over time are highly variable, coming mainly from self-report surveys prone to multiple biases. Thus, validated psychophysical olfactory testing is sorely needed to establish...

Respiratory failure is a serious complication of H1N1 influenza that, if not properly managed, can cause death. When mechanical ventilation is not effective, the only way to save the patient's life is extracorporeal membrane oxygenation (ECMO). A prolonged type of cardiopulmonary bypass, ECMO is a high-cost management modality compared to other con...

Several models have been developed to measure the severity of illness in intensive care unit (ICU) patients, It is suggested that the models should be customized depending on the characteristics of different population of patients. This study is aimed to assess and modify the performance of Acute Physiology and Chronic Health Evaluation II (APACHE-...

Abstract It seems control of HIV infection spread is lag behind research for new treatments, especially in developing countries. Intravenous drug use is a major risk factor for HIV infection. Addiction control is a reasonable measure for HIV transmission prevention. Implementing treatments for opiate dependence such as: training drug dependence sid...

Ventilator-associated pneumonia (VAP) is one of the most common Intensive Care Unit (ICU)-acquired infection. The aim of this study was to compare the clinical outcome of continuous and intermittent administration of piperacillin-tazobactam by serial measurements of the Clinical Pulmonary Infection Score (CPIS). Groups were designed as parallel and...

Background: An outbreak of antibiotic resistant gram-negative bacteria, particularly Acinetobacter, in intensive care unit is of great importance for intensivists due to high mortality and low effective therapy. Objective: We aimed to evaluate antibiotic susceptibility of isolated gram-negatives from patients with ventilator- associated pneumonia (...

Background In previous decades several studies have been performed demonstrating that providing appropriate nutritional support to intensive care unit patients affects complications, time of mechanical ventilation, length of ICU stay, and risk of death. In this study we provided a report of nutrition statuses in Masih Daneshvari's ICU as compared t...

In preparation for pandemic HINI or H1N1 influenza (H1N1) it is necessary to identify factors associated with mortality of patients with HINI and hospital admissions to intensive care unit (ICU) of patients diagnosed in 2009 with HINI. To describe the clinical and epidemiological features associated with 2009 HIN1 mortality and ICU patient admissio...

Background Oseltamivir-resistant cases were reported during the 2009 pandemic influenza outbreak and therefore, widespread emergence of oseltamivir-resistant 2009 H1N1 virus is imaginable. Underlying medical conditions like immunosuppression increase the chance of oseltamivir resistance. Materials and Methods In a retrospective cross-sectional stu...

Background: The aim of this study is to compare the performance of five applied general severity scoring systems and their ability to predict mortality rate for the intensive care unit patients: Simplified Acute Physiology Score II (SAPS II), Mortality Probability Model II at admission (MPM II0), at 24 hours (MPM II24), at 48 hours (MPM II48) and o...

Avicenna (Abu Ali Sina in Persian) was a Persian polymath and the foremost physician and philosopher of his time and the ensuing decades. He was born around 980 in Greater Khorasan, to a Persian family. During the Islamic Golden Ages, Avicenna created an extensive corpus of works.
