ABSTRACT
The fluorinated pyrimidine 5-fluorouracil (5-FU) is an anticancer agent used in most adjuvant and palliative treatment regimens for colorectal cancer. Neurotoxicities are considered extremely rare side effects of 5-FU. Here, we report a case of 5-FU-induced encephalopathy, manifesting as seizures and delirium, in an era of oxaliplatin-containing chemotherapy. If ammonia levels are elevated, lactulose may be considered in the initial management of neuropsychiatric complications from 5-FU.
ABSTRACT
OBJECTIVE: To develop guidelines as to which asymptomatic male patients with genital human papillomavirus (HPV) infection need further evaluation of the urethra, we studied two screening methods: urethroscopy and voided urethral cytology. METHODS: In a four-year period, 135 asymptomatic men underwent complete screening for HPV infection. They were evaluated because of HPV-related genital disease in their female sex partners or visible genital lesions, or both. RESULTS: Of the 135 patients, 21 (16%) had no clinical, subclinical, cytologic, or urethroscopic evidence of disease, and 114 (84%) had biopsy-proven HPV infection. Of these 114 patients, only 14 (12.3%) had intraurethral condyloma. All of these 14 patients had current or historical evidence of meatal or perimeatal "sentinel" lesions. They constituted 29.8 percent of 47 such patients with sentinel lesions. In 5 patients (4%), results of voided urine cytology were positive for condyloma cells, but only 1 of these had visible intraurethral disease. Of the 14 patients with urethral disease, only 1 (7%) had positive results of urine cytology. CONCLUSIONS: These observations suggest that any asymptomatic male patient undergoing screening for condyloma acuminatum who has a history of or demonstrable subclinical or grossly visible perimeatal or meatal HPV infection should undergo urethroscopy and that voided urine cytology is not a reliable or cost-effective test for the detection of visible intraurethral disease.

A 3-year-old boy presented with decreased renal function, hypertension, obesity and developmental delay. Evaluation of his kidneys revealed blunting of the calyces and multiple renal cortical cysts. Ophthalmologic evaluation showed no abnormalities on examination but electroretinography showed reduced retinal function suggesting a diffuse retinal disorder. Based on the clinical presentation with the associated abnormalities, the diagnosis of Bardet-Biedl syndrome, a form of the Laurence-Moon-Biedl syndrome was made. This syndrome should be considered and specific diagnostic efforts should be made in pediatric patients who present with renal failure and obesity.

An epidemic of gastroenteritis in a teaching hospital affected 57 patients and 69 staff over a 26-day period. The index case was a patient admitted with acute abdominal pain and diarrhea two days prior to the outbreak. The epidemic curve indicated person-to-person transmission. The incubation period, duration and types of symptoms were typical of Norwalk gastroenteritis, and Norwalk-like virus particles, serologically different from the prototype Norwalk virus strain, were observed in 17 of 20 fecal specimens examined by immune-electron microscopy.
