The effects of moderate and severe hemorrhage on the cardiac output and its distribution have been studied in the rat. In moderate hemorrrhage, cerebral and adrenal blood floware well maintained through localized vasodilatation while most other organs show increased vascular resistance and diminished blood flow. After severe hemorrhage, despite further changes in territorial resistances, the bl...

Few dental procedures have fatal complications, but severe postoperative hemorrhage can result in preventable death. This report describes a case of postextraction hemorrhage that led to airway compromise necessitating emergency airway management. This complication is rare, and a review of the literature revealed little in the way of case reports and treatment protocols. This article reviews th...

Introduction: Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood. The classic triad of HSP consists of nonthrombocytopenic purpura, arthritis/arthralgia, and gastrointestinal complaints. Pulmonary hemorrhage and cardiac involvement are rare complications of HSP. Case Report: We report the case of a 10-year-old girl with HSP complicated by both severe mitral regurgitation ...

Spontaneous renal hemorrhage is an unusual and severe complication of urinary tract infection. A 73-year-old woman with diabetic nephropathy was admitted with fever and intermittent abdominal pain for one day. She had pyuria and was treated for a presumed urinary tract infection. Initial abdominal ultrasonography showed only bilateral renal atrophy. Subsequently, she developed more severe abdom...

Human infection with Leptospira interrogans can be life-threatening. Multiple organ involvement frequently presents with liver and kidney failure, less commonly including severe hemolysis and pulmonary hemorrhage syndrome. Here, we present a fulminant case of leptospirosis presenting with hemolysis and pulmonary hemorrhage. A formerly healthy 34 year old patient presented to a rural hospital wi...

Spontaneous cerebral hemorrhage or intracranial hemorrhage accounts for 10-15% of all strokes. Intracranial hemorrhage is much less common than ischemic stroke, but has higher mortality and morbidity, one of the leading causes of severe disability. Various alterations, among these the endocrine were identified when an intracerebral hemorrhage, these stress-mediated mechanisms exacerbate seconda...

Controversy exists regarding management of children newly diagnosed with immune thrombocytopenic purpura (ITP). Drug treatment is usually administered to prevent severe hemorrhage, although the definition and frequency of severe bleeding are poorly characterized. Accordingly, the Intercontinental Childhood ITP Study Group (ICIS) conducted a prospective registry defining severe hemorrhage at dia...

Severe maternal thrombocytopenia resulting in hemorrhage is often associated with high mortality. Three cases of severe maternal thrombocytopenia in association with heparin-induced thrombocytopenia (HIT), HELLP syndrome, and systemic lupus erythematosus (SLE) were successfully managed using intravenous immunoglobulin (IVIG). IVIG can reduce the severity of thrombocytopenia and hemolysis, stabi...

BACKGROUND Obstetric hemorrhage is the leading cause of severe maternal morbidity and of preventable maternal mortality in the United States. The California Maternal Quality Care Collaborative developed a comprehensive quality improvement tool kit for hemorrhage based on the national patient safety bundle for obstetric hemorrhage and noted promising results in pilot implementation projects. O...

PURPOSE To evaluate the frequency and clinical characteristics of postoperative hemorrhage as a complication of partial nephrectomy. MATERIALS AND METHODS The demographics, physical statistics, tumor size, R.E.N.A.L. nephrometry score, operative method, warm ischemic time, and presence of postoperative hemorrhage and its severity and method of intervention were examined in 300 partial nephrec...
