RESUMEN
OBJECTIVE: Despite the high prevalence of hospitalization for left iliac fossa tenderness, there is a striking lack of randomized data available to guide therapy. The authors hypothesize that an oral antibiotic and fluids are not inferior to intravenous (IV) antibiotics and 'bowel rest' in clinically diagnosed acute uncomplicated diverticulitis. METHOD: A randomized controlled trial was constructed in two District General Hospitals. All clinically diagnosed patients presenting with acute uncomplicated diverticulitis were eligible for the study. Oral and IV regimens utilizing ciprofloxacin and metronidazole were compared. The primary outcomes studied were surrogates for resolution of symptoms (including tenderness on day 3 and length of stay) and failure of oral therapy. Secondary endpoints studied were serial constitutional and biomarker trends. RESULTS: There were 41 patients in the oral arm and 38 in the IV arm (n = 79). No patient had to be converted to IV antibiotics from the oral group. There was a complete resolution of symptoms in both groups. Tenderness was equivalent in both groups on day 3. Among secondary endpoints, a serial decrease in C reactive protein was the best serological predictor of resolution for both groups. CONCLUSION: Oral antibiotics are not inferior to intravenous antibiotics in achieving resolution of clinically diagnosed diverticulitis.

Obtaining an adequate supply of foetal dopaminergic tissue to treat Parkinson's disease by neural transplantation can be difficult. In this study primary cultures of human foetal cerebral cortex cells were transfected, using cationic lipids, with a eukaryotic expression vector (pCIneo-THI) containing the cDNA for human tyrosine hydroxylase isoform I (TH). Cortical cells from human (10-14 week) foetuses were cultured for 11 days in vitro and transfected twice with pCIneo-THI during this time. The double transfection process resulted in 3-4% of the cells becoming TH positive. When grafted into the striatum of 6-OHDA lesioned rats the transfected foetal cerebral cortex cells reduced amphetamine-induced circling behaviour by 75%, while grafts of untransfected cells had no significant effect on turning. TH transfected foetal cerebral cortex cells may therefore be a useful alternative supply of tissue for use in neural transplants to treat Parkinson's disease.
