Although there is common agreement and occasionfal mention of the fact that nephritis once healed does not recur, there has been little evidence presented in the literature to substantiate this impression. Longcope (1) reports 4 cases out of a series of 24 with healed acute nephritis in whom beta hemolytic streptococci were found subsequently. Two of these, in a single throat culture each, reve...

Background.  The importance of bacteria other than group A streptococci (GAS) in different clinical presentations of cellulitis is unclear, commonly leading to treatment with broad-spectrum antibiotics. The aim of this study was to describe the etiological and clinical spectrum of cellulitis and identify clinical features predicting streptococcal etiology. Methods.  We prospectively enrolled 21...

background: glucose-6-phosphate dehydrogenase (g6pd) deficiency is the most common enzyme disorder in human. the aim of this study was to determine the prevalence of g6pd deficiency among children and evaluate its association with abo/rh blood groups.   method: blood samples of 3401 asymptomatic children were analyzed and compared with 317 children who were admitted to hospital because of hemol...

Hemolytic-uremic syndrome is a clinical syndrome characterized by acute renal failure, microangiopathic hemolytic anemia, and thrombocytopenia that often follows infection by Shiga toxinor verotoxin-producing strains of Escherichia coli. Because thrombocytopenia and platelet activation are hallmark features of hemolytic-uremic syndrome, we examined the ability of Shiga toxin to bind platelets b...

NIPPV: noninvasive positive pressure ventilation INTRODUCTION Ecthyma is an invasive form of impetigo that penetrates deep into the dermis. This cutaneous infection is characterized by a crusted papule or plaque beneath which a deep ulcer forms. Although typically associated with group A b-hemolytic streptococci, other pathogens have the ability to produce an ecthyma. Here we present a case of ...

One hundred thirty-seven isolates of beta-hemolytic streptococci were recovered from 623 pharyngeal cultures. Twenty-nine percent of these were group A, 10% were group B, 31% were group C, 11% were group F, 12% were group G, and 7% could not be grouped. The significance of non-group A isolates in pharyngitis could not be evaluated in the absence of viral and serological studies. Hemolytic strep...
