We evaluated the results of treatment for ninety-seven patients (106 infections in ninety-eight hips) who had had either an infection after a total hip arthroplasty or positive intraoperative cultures of specimens obtained during revision of a total hip arthroplasty for presumed aseptic loosening. The patients were managed according to various protocols on(More)
A form of dominantly inherited olivopontocerebellar atrophy (OPCA) occurs commonly in persons of Spanish ancestry in northeastern Cuba. Its prevalence in the Province of Holguin is 41 per 100,000, a figure much higher than that found in western Cuba or in other parts of the world. The high prevalence is probably the result of a founder effect, but might be(More)
Eleven autopsies of patients from the large founder-population with dominantly inherited spinocerebellar ataxia 2 (SCA2) in Holguín, Cuba, were analyzed by the same observers, including quantitative microscopic evaluation. As expected in this disease with highly unstable polyglutamine expansions, considerable variability was observed, which correlated to(More)
BACKGROUND Endoscopic injection of normal saline solution is reportedly an effective treatment for bleeding ulcers. If it is as effective as standard therapy, low cost, wide availability, and lack of injury would make saline solution injection an attractive option. METHODS Patients with clinical evidence of major bleeding from an ulcer with active(More)
BACKGROUND Ectopic pregnancies associated with negative urine or serum pregnancy test by radioimmunoassay usually demonstrate either nonviable trophoblast or absent production of beta-hCG by the ectopic pregnancy. CASE We report a patient with intra-abdominal hemorrhage caused by a ruptured ampullary ectopic pregnancy who had undetectable serum and urine(More)
A time course of tissue ionic changes, and their relation to ultrastructural findings during reperfusion following a 15-min global ischemic brain insult was studied in a dog model. Parietal cortex was analyzed for Ca, Na, K, Mg and Fe in controls and after 10 min, 2, 4, and 8 h of reperfusion. After 8 h of reperfusion, the mean values (mumol/g tissue wet(More)
Ten patients with the acquired immunodeficiency syndrome and an endoscopic erosive/ulcerative lesion in esophagus (4), stomach (3), or colon (3) were prospectively studied with multiple biopsies (244 biopsies from 33 sites) to determine: 1) the frequency of positive tests for cytomegalovirus (CMV) in the lesions versus normal mucosa, 2) the influence of(More)
INTRODUCTION The mitochondria, subcellular organelles which possess their own DNA (mtDNA), produce most of the energy, in the form of ATP, which is necessary for life. This mtDNA may have diverse molecular defects which have been associated with a great variety of clinical syndromes. Deletions in mtDNA are one of the common mutations in patients with(More)
Cultures of the fallopian tube, cul-de-sac, and cervix were obtained from 50 patients undergoing exploratory laparotomy for ectopic pregnancy. Chlamydia trachomatis was cultured from the cervix in four patients (8%). All the cultures from the fallopian tube or cul-de-sac were negative. Immunofluorescent stain of deparaffinized cross-sections of fallopian(More)
A Meckel's diverticulum is an unusual site of gastrointestinal bleeding in adults. Bleeding often results from ulceration of ileal mucosa that lies adjacent to ectopic gastric mucosa. We report on a 27-yr-old man who bled from a Meckel's diverticulum after receiving oral ibuprofen, a nonsteroidal antiinflammatory drug. Examination of the resected(More)
