Fat emboli occur in all patients with long-bone fractures, but only few develop systemic dysfunction, particularly the triad of skin, brain, and lung dysfunction known as fat embolism syndrome (FES). Here we review FES literature under different subheadings.The incidence varies from 1-29%. The etiology may be traumatic or, rarely, nontraumatic. Various factors increase FES. Mechanical biochemical theories have been proposed for pathophysiology clinical manifestations include respiratory...
Vascular air embolism (VAE) is known since early nineteenth century. It the entrainment of or gas from operative field other communications into venous arterial vasculature. Exact incidence VAE difficult to estimate. High risk surgeries for are sitting position and posterior fossa neurosurgeries, cesarean section, laparoscopic, orthopedic, invasive procedures, pulmonary overpressure syndrome, decompression syndrome. Risk factors site 5 cm above heart, creation pressure gradient which will...
Necrotizing fasciitis (NF) is a fatal aggressive infectious disease. We aimed to assess the major contributing factors of mortality in NF patients. A retrospective study was conducted at single surgical intensive care unit between 2000 and 2013. Patients were categorized into 2 groups based on their in-hospital outcome (survivors versus non-survivors). During a14-year period, 331 patients admitted with mean age 50.8 ± 15.4 years 74 % them males Non-survivors (26 %) 14.5 older (p = 0.001) had...
Resistance to last-line polymyxins mediated by the plasmid-borne mobile colistin resistance gene (mcr-1) represents a new threat global human health. Here we present complete genome sequence of an mcr-1-positive multidrug-resistant Escherichia coli strain (MS8345). We show that MS8345 belongs serotype O2:K1:H4, has large 241,164-bp IncHI2 plasmid carries 15 other antibiotic genes (including extended-spectrum β-lactamase blaCTX-M-1) and 3 putative multidrug efflux systems, contains 14...
Aneurysmal subarachnoid hemorrhage (aSAH) is a dreadful acute neurological condition with an overwhelmingly high rate of associated morbidities and mortality. Despite leaping advancement in neurosurgical techniques imaging modalities, there no substantiative improvement the overall prognosis for aSAH. Cerebral vasospasm remains predominant cause morbidities. Human albumin has been used different conditions, including head trauma, intracerebral hemorrhages, ischemic strokes, favorable...
Abstract Background Necrotizing Fasciitis (NF) is a life-threatening infection characterized by rapid tissue destruction and high mortality. The role of timely diagnosis surgical intervention in improving patient outcomes remains debated. This study investigates the impact “time to diagnosis” (TTD) treatment” (TTS) on NF patients, with specific focus first six hours critical diagnosis. Methods A retrospective analysis was conducted for patients hospitalized between June 2016 2023....

Methods This retrospective involved all adult patients, 15 years age or older, diagnosed with multidisciplinary at Hamad General Hospital between January 2010 December 2012. Results A total 106 patients were enrolled. mean incidence was 5.0 per 1000 ventilator-days. It predominant among younger group (<60 years), male (80.2%),...
Pneumocephalus is the presence of air in cranial cavity. When this intracranial causes increased pressure and leads to neurological deterioration, it known as tension pneumocephalus (TP). TP can be a major life-threatening postoperative complication, especially after evacuation chronic subdural hematoma. We report case hematoma review literature.A 70-year-old man developed right-sided weakness being admitted with minor head trauma few weeks earlier. He was found have underwent burr-hole...
Necrotizing fasciitis (NF) is still remained a dreaded disease with high morbidity and mortality due to rapidly progressive necrotizing infection. Objective: Review recent available literature on compare it our publications. Data Source: Local international published NF from early nineties 2012; Midline pub Med search using the term “necrotizing fasciitis”. Synthesis: more common in male patient, frequently polymicrobial. Common site of extremities. classified according microbes. co-morbid...
