An outbreak of acute hemorrhagic conjunctivitis (AHC) occurred in Rio de Janeiro in 2004. Coxsackievirus A24v (CA24v) was identified as the etiologic agent, and partial sequences from the VP1 gene show that the isolates are closely related to CA24v viruses that previously caused AHC epidemics in South Korea and French Guiana.

We report a case of acute idiopathic scrotal edema (AISE) in a 4-year-old boy who presented with acute scrotal pain and erythema. The clinical features, ultrasound appearance, and natural history of this rare diagnosis are reviewed. In this report, we highlight the importance of good ultrasound technique in differentiating the etiology of the acute scrotum and demonstrate the color Doppler "Fou...

background: thrombolytic therapy is the only approved treatment for acute cerebral ischemia. the hemorrhagic transformation is the greatest complication of this treatment, which may occur after recanalization of occluded artery. the aim of this study was to determine factors associated with clinical improvement and worsening in patients with acute ischemic stroke treated with intravenous thromb...

Acute hemorrhagic leukoencephalitis of Weston Hurst is at the extreme end of the spectrum of demyelinating diseases. It typically follows a viral upper respiratory infection and evolves rapidly to coma and death. "Ball and ring" hemorrhages appear in the centrum semiovale of the brain, associated with mononuclear and neutrophil infiltrates, surrounded by demyelination spreading out from fibrin-...

A seventy-six-year-old lady with poor vision of the left eye due to previous retinal detachment presented with acute visual loss of her right eye secondary to central retinal artery occlusion. Clinical examination showed a pale right optic disc, macular edema, and a cherry red spot. Optical coherence tomography done four hours after onset showed right acute cystoid macular edema and diffuse inn...

Hemorrhagic cystitis is a recognizable complication of cyclophosphamide (CYP) attributable to its lively metabolite acrolein, which produces urothelial injury. The study intended examine the uroprotective efficacy total ginsenosides in Chinese ginseng (TGCG) CYP-induced hemorrhagic cystitis. In total, 24 virgin female rats were randomized into four groups as follows: group 1 (control group; inj...

Following onset of acute cardiogenic pulmonary edema in 21 patients, increases in hematocrit, plasma protein concentration, and colloid osmotic pressure were associated with decreases in plasma volume. Accordingly, there was a loss of hypo-oncotic fluid into the extravascular spaces. Following treatment with oxygen, furosemide, and morphine sulfate and reversal of clinical and radiographic sign...

A prospective clinical study was done on 20 patients referred for computed tomography within 28 hr of a cerebral ischemic event. The patients were scanned before, immediately after, and 3 hr after a high dose of intravenous contrast medium was administered to produce prolonged high blood iodine levels. In seven patients the delayed scan demonstrated a heretofore undescribed type of contrast enh...
