OBJECTIVES:There are few prospective studies estimating the prevalence of hepatitis A in chronic liver disease patients. Furthermore, there are minimal cost-comparative data as to whether or not screening for hepatitis A exposure before immunization is an effective fiscal strategy. The objectives of this study were to determine the prevalence of prior(More)
Esophageal emergencies are a common problem facing practicing gastroenterologists and it is important to know what therapies are indicated for different situations. Patients ingesting caustic agents should be monitored intensively for signs of perforation and ultimately for signs of stricture development. Foreign bodies impacted in the esophagus should be(More)
Focal motor seizures are commonly a symptom of nonketotic hyperglycemia (NKH). Posture-induced motor seizures are less common but have been reported in some patients with this disorder. We report the first case of gaze-evoked sensory (visual) seizures in nonketotic hyperglycemia. Both seizures and ictal EEG findings disappeared shortly after hyperglycemia(More)
Children with acute promyelocytic leukemia were treated with aggressive daunomycin induction and 6-mercaptopurine and methotrexate maintenance. The remission rate was 8 out of 10 fully evaluable patients. Three are still alive up to 32 months. With vigorous induction therapy, occurrence of disseminated intravascular coagulation was rare. Only one case of(More)
Ulcerative colitis is associated with a number of extra-intestinal complications; including the infrequent occurrence of thromboembolic diseases. Acute cerebral venous thrombosis in the setting of ulcerative colitis is extremely rare with only about 40 cases reported since 1963. We describe a 19 year-old patient with a three year history of ulcerative(More)
The U.S. Army administers the hepatitis A virus (HAV) vaccination for prophylaxis against HAV infection. There is little comparative data as to whether prescreening for previous HAV infection before immunization is less costly than universal vaccination. We designed a study to determine the prevalence of previous HAV infection in U.S. Army recruits and then(More)
Transient global amnesia, epilepsy, and migraine are three common neurologic disorders likely to be encountered by military physicians. These three entities share many clinical, electroencephalographic, and pathophysiologic characteristics. We report a patient who exemplifies the indistinct boundaries among these conditions and whose response to treatment(More)
As treatment for chronic hepatitis C virus (HCV) infection has advanced over the past decade, efforts have evolved to retreat patients who did not achieve a sustained virologic response to previous antiviral regimens. Retreating nonresponders to interferon alfa monotherapy with a combination of interferon and ribavirin yields a sustained virologic response(More)
