The clinical course and treatment outcome of scorpion envenoming in 293 children was studied in a hospital at Mahad in Raigad district of Maharastra. 111 (38%) children who reported 1-10 hours (mean 3.5 hours) after sting had hypertension, 87 (29.6%) with tachycardia reported within 1-24 hours (mean
An 88-year-old Caucasian man of Italian ancestry came into our clinic with multiple, painful purple-red "growths" on his left foot that he'd had for several years. The patient had no systemic complaints (no fever, chills, weight loss, night sweats). He had a history of hypertension, a cardiac valve
We present an overview of the currently known molecular basis of red cell membrane disorders. A detailed discussion of the structure of the red cell membrane and the pathophysiology and clinical aspects of its disorders is reported. Generally speaking, hereditary spherocytosis (HS) results from a
High-altitude pulmonary edema (HAPE) is the predominant cause of death due to high-altitude illness. At first sight, the observation that mountaineers regularly consume red wine in order to "feel better" seems to be paradoxical because, especially at higher altitudes, alcohol consumption could be
A hydrops fetalis and multicystic encephalomalacia were diagnosed in a neonate who was one of twins. The co-twin had died 5 weeks prior to delivery. The most likely explantation for both hydrops and multicystic encephalomalacia was fetal anemia caused by a red cell pyruvate kinase deficiency, and
A young woman with acquired chronic pure red cell aplasia (PRCA) gave birth to 3 infants with foetal hydrops. The 1st infant died shortly after birth, while the 2nd was stillborn with severe anaemia. Both had signs of increased erythropoiesis at autopsy. The 3rd infant was saved by foetal
Specific red flag clinical signs in ophthalmology might indicate serious underlying systemic disease. This review illustrates five big red flags in neuro-ophthalmology of interest to comprehensive ophthalmologists. These clinical signs include: (i) retinochoroidal venous collaterals, (ii) optic disc
We experienced a patient who suffered noncardiogenic acute pulmonary edema after transfusion of packed red blood cells which contained antigranulocyte antibodies. The data suggested that complement activation and the release of polymorphonuclear protease were involved in the pathogenesis of the
Having direct access to the fetoplacental circulation by ultrasound-directed needle puncture has led to therapeutic interventions for fetal anemia and thrombocytopenia. Most cases of red cell alloimmunization associated with fetal anemia are caused by the antibody to the D red cell antigen. The
We treated 69 eyes of 44 patients who had clinically significant macular edema with argon or krypton laser photocoagulation or both. The mean initial visual acuity was 20/40. Patients were followed for 6 to 63 (mean 19.7 +/- 11.0) months. There was a mean loss of three letters in acuity, but the
Transfusion of stored red blood cells (RBCs) is associated with increased morbidity and mortality in trauma patients. Pro-oxidant, pro-inflammatory, and nitric oxide (NO) scavenging properties of stored RBCs are thought to underlie this association. In this study we determined the effects of RBC
The differential diagnosis of eyelid erythema and edema is broad, ranging from benign, self-limiting dermatoses to malignant tumors and vision-threatening infections. A definitive diagnosis usually can be made on physical examination of the eyelid and a careful evaluation of symptoms and exposures.
We will consider an array of genetic disorders of the red cell membrane. Some affect well-known genes. The mutations of most cases of hereditary spherocytosis (HS) are located in the following genes: ANK1, SPTB, SLC4A1, EPB42 and SPTA1, which encode ankyrin, spectrin beta-chain, the anion exchanger
