We are seeing an increased number of complications in intravenous drug abusers who resort to injecting the groin for vascular access (the "groin hit"). Vascular complications include venous thrombosis, arteriovenous fistula, mycotic aneurysm, ruptured pseudoaneurysm, and dissecting hematoma. Soft tissue complications include cellulitis and abscess. The(More)
Our busy, urban emergency room is staffed by radiology residents after working hours. To determine the accuracy of our residents' interpretations of emergency cranial computed tomographic (CT) scans, the authors reviewed the preliminary reports of our residents for a two-month period. A total of 289 cranial CT scans were retrospectively reviewed and the(More)
Common marmosets (Callithrix jacchus, n = 18) were trained to discriminate between rewarded and non-rewarded objects (simple discriminations, SDs) and to make conditional discriminations (CDs) when presented sequentially with two different pairs of identical objects signifying reward either in the right or left food well of the Wisconsin General Test(More)
In order to investigate the effects of stem cell grafts on water maze deficits in aged (22-month-old) rats, three groups of aged rats, assigned by pre-training latency scores to unimpaired, impaired control and impaired grafted groups, were compared with young (five-month-old) controls, six to eight weeks after implantation of cells from the conditionally(More)
Late fetal CA1 hippocampal grafts and stem cell grafts from the conditionally immortal MHP36 clonal line derived from the H-2Kb-tsA58 transgenic mouse neuroepithelium both improved spatial deficits in rats with ischaemic CA1 damage induced by four-vessel occlusion (4VO). However, the distribution of fetal and MHP36 grafts differed. Fetal cells lodged in(More)
Overactive bladder (OAB) is a symptom syndrome including urgency, frequency, and nocturia - with or without incontinence. It is a common manifestation of detrusor overactivity (DO). DO is a urodynamic observation of spontaneous or provoked contractions of the detrusor muscle is seen during the filling phase of the micturition cycle. OAB is, therefore, both(More)
