Comparative StudyComparing the aspartate aminotransferase (AST) to platelet ratio index (APRI) between African American and White veterans with chronic hepatitis C.
The study of noninvasive markers of fibrosis, such as aspartate aminotransferase (AST) to platelet ratio index (APRI), have been limited in African American populations. Given the disparate outcomes of chronic hepatitis C in African American populations, comparative analyses of the APRI score should be undertaken. Compare the diagnostic accuracy of the APRI score for significant fibrosis and cirrhosis in a sample of African American and white veterans with chronic hepatitis C in the southeastern United States. ⋯ The APRI score displayed similar performance in African Americans and whites. A threshold of 1.0 can reliably exclude cirrhosis in African American veterans with chronic HCV infection.

Wasp bites usually bring temporary discomfort and pain, but on occasion, they can cause serious infections and fatal allergic reactions. We report on a patient who experienced massive wasp stings and developed multiple organ failure, including acute kidney, hepatic failure, and circulatory collapse 4 days later. He was treated with aggressive fluid resuscitation, inotropic agent, intravenous injection of steroids, broad-spectrum antibiotics, and hemodialysis. ⋯ Recovery of renal function was delayed, and the patient needed temporary regular hemodialysis. The pathology of kidney biopsy showed acute tubulointerstitial nephritis. This case shows that toxic reactions following massive wasp attacks may happen several days after the fact and result in severe, multiorgan system dysfunction.

Case ReportsTumor-induced osteomalacia (TIO): atypical presentation.
Tumor-induced osteomalacia is a rare acquired condition characterized by phosphaturia, hypophosphatemia and osteomalacia. We report an unusual presentation in a 15-year-old healthy male with a two-week history of cough and chest pain. The chest radiograph showed right middle lobe opacity and chest CT revealed a mass in the extra pleural space. ⋯ Diagnosis was confirmed with the above findings and hypophosphatemia. The patient's symptoms resolved after complete surgical excision of the mass. Tumor-induced osteomalacia, although a rare disorder, can be a diagnostic challenge, especially in patients presenting with atypical symptoms.
