Previous studies have noted the abundance of collagen in human erectile tissues and the association of altered collagen content with erectile dysfunction. We investigated these notions by studying the collagen characteristics of biopsies from the corpus cavernosum of men who required surgical correction of their sexual dysfunction. Histologic analysis(More)
OBJECTIVE To assess the prevalence of bacterial vaginosis (BV) in asymptomatic pregnant women and its association with preterm birth (PTB) and premature rupture of membranes (PROM). METHODS In a cohort study 1,006 pregnant women between 16-28 weeks' gestation were screened for BV (Nugent's criteria) and for lower genital tract infection. Women were(More)
Intracranial Hodgkin's disease is very rare and is often a terminal event. The case of a 33-year-old man who relapsed in the anterior pituitary gland without other evidence of disease 6 months after extended field radiation therapy for Stage IIA Hodgkin's disease is presented. He remains well with no evidence of disease five years after surgery and(More)
OBJECTIVE Fine needle aspiration (FNA) is emerging as a rapid and minimally invasive tool in evaluating lymphadenopathy associated with human immunodeficiency virus (HIV). We evaluated the role of FNA in differentiating various causes of lymphadenopathy in patients with HIV and correlated the cytological diagnosis with CD4 counts. METHODS Seventy-nine(More)
Plasma urea and urate concentrations were determined daily for up to seven days in 40 pregnant women who had been admitted to hospital because of proteinuric hypertension and who were then allocated at random to either complete rest in bed or to being allowed to move freely in the ward. Neither management was superior to the other in improving renal(More)
One hundred patients took part in a randomized controlled trial to test the efficacy of three 1 g doses of cephaloridine in preventing infection after abdominal hysterectomy. The first dose was given as an intravenous bolus at the commencement of surgery and the second and third as intramuscular injections 6 and 12 hours later. Given in this way,(More)
We studied the pathological specimens obtained from 24 impotent men who underwent proximal penile vein ligation and 6 potent men who underwent total penectomy as part of male-to-female transsexual surgery to determine if a correlation exists between venous pathology and surgical outcome. Pathology specimens, consisting of cavernosal tissue and penile veins,(More)
A 15-year-old male was treated secondary to sustaining a moderate traumatic brain injury (moderate TBI). Symptom self-report, and computerized and paper-and-pencil-based neurocognitive, vestibular/ocular motor, and imaging data were used throughout to document impairment and recovery. The patient demonstrated persistent emotional lability concurrent with(More)
Renal-cell carcinoma (RCC) during pregnancy is rare. Laparoscopic nephrectomy has been used effectively and safely in nonpregnant patients with RCC. We report a case of a 34-year-old pregnant woman with RCC, which we believe to be the first such case to be managed by laparoscopic nephrectomy.
Forty patients participated in a randomized controlled trial of complete bed rest versus ambulation as desired in the management of proteinuric hypertension during pregnancy. Daily increases in serum human placental lactogen and oestriol concentrations were greater in the rested group. An especially 'at risk' group of 10 patients with both hyperuricaemia(More)
