摘要:
Twelve patients with erectile impotence related to diabetic neuropathy were treated with a vacuum device, Pos-T-Vac. Efficacy of the device and psychological evaluation (Dyadic Adjustment Scale for marital satisfaction and Hamilton Rating Scale for depression) were performed before and 3 months after treatment. Vacuum therapy was successful in 75% of the patients. Patients with successful impotence treatment and normal baseline marital satisfaction scores showed a modest increase in the scores of marital satisfaction (from 114 ± 3 points, baseline, to 121 ± 3 points, posttreatment; p <0.05). Vacuum therapy for the treatment of erectile dysfunction due to diabetic autonomic neuropathy appears to be safe and effective.

摘要:
To identify potential barriers to use of autologous blood procurement to minimize homologous blood transfusion needs during elective surgery, the authors conducted a telephone survey of 120 blood bank directors, representing 138 Ohio hospitals. The prevalence of autologous blood procurement facilities, estimated volume of autologous blood, and attitudes and perceptions of the directors toward autologous blood predeposit programs were assessed. Analysis of the data indicated that 30% of Ohio hospitals have autologous blood procurement facilities; larger hospitals were more likely to have this facility. Overall, 5.5% of transfusions involve predeposited autologous blood. No significant differences were found according to hospital bed size or whether the hospital had a procurement facility. Blood bank directors perceived surgeons to be knowledgeable about autologous predeposit; patient demand and surgical practice were felt to be more effective in promoting the use of autologous blood at the hospital than were blood bank efforts. Directors who had autologous predeposit procurement facilities perceived that the facility provided a marketing advantage. Respondents from larger hospitals were more likely to perceive that these programs could be financially self-sufficient. The authors conclude that an economic cost-benefit analysis of hospital-based autologous blood procurement programs is important. Positive findings may influence transfusion services to adopt autologous blood procurement programs, whereas negative findings may convince hospitals that community blood donor facilities can provide better autologous blood procurement.

摘要:
Bacterial isolates obtained from fecal cultures of U.S. adults in Guadalajara, Mexico, with diarrhea developing during the summers of 1987, 1988, and 1989 were tested for in vitro antimicrobial susceptibility. No resistance was seen among 220 enterotoxigenicEscherichia coliisolates nor among 89Shigellastrains to aztreonam, norfloxacin, ciprofloxacin, gentamicin, or furazolidone. High level (>1000 µg/ml) resistance to trimethoprim/sulfamethoxazole (TMP/SMX) was found in 7% ofE. coliand 3% ofShigellastrains. Susceptibility patterns of 27E. colistrains derived from fecal cultures of Mexican infants in Guadalajara with diarrhea during the same time period showed similar results, possibly reflecting the presence of a common microbial reservoir. The study serves as a baseline for newer antimicrobials (fluoroquinolones and aztreonam) where no resistance is currently seen and provides evidence of the continuing value of TMP/SMX for therapy of diarrhea among travelers to Guadalajara and perhaps other areas of Mexico.

摘要:
Conventional approaches to indexing medical literature include the human assignment of terms from a controlled vocabulary, such as MeSH, or the computer assignment of all words in the title and abstract as indexing terms. Human indexing suffers from inconsistency, while word-based indexing suffers from the multiple meanings of words. SAPHERE is a computer program designed to provide indexing using controlled terms that are assigned by computer, based on their occurrence in the title and abstract. In this first evaluation of SAPHIRE, the authors compared the retrieval performance of the three indexing approaches—human-based MEDLNE with text words; machine-based SAPHIRE with text words; and text words only— for searches by measuring recall and precision for each search using a test collection of 200 abstracts. The abstracts were judged by human reviewers for relevance as applied to 12 literature queries. The results suggest that text word indexing is more effective than indexing with MeSH terms. SAPHIRE's indexing performance was slightly inferior but the program has other advantageous features.

摘要:
The role of antidiuretic hormone (ADH) in the renal concentration defect and hemodynamic changes in protein malnutrition was evaluated in rats with diabetes insipidus (DI) after 2 weeks of low protein feeding. Free water reabsorptive capacity (TH2O), glomerular filtration rate (GFR), and renal plasma flow (RPF) were measured in the protein deprived rats and in DI rats fed a normal protein diet. The effect of urea supplementation of the low protein diet on renal concentrating capacity was also evaluated. In addition, the renal hemodynamic response to acute administration of ADH was measured and correlated with changes in plasma renin concentration and renal renin content (RRC). Protein deprivation in DI rats resulted in reduced urine osmolality and urea excretion, differences which were reversed by urea supplementation. Protein deprivation did not affect free water reabsorptive capacity but did reduce GFR and RPF. Acute ADH administration significantly increased GFR and RPF in protein-deprived rats; these changes were associated with a reduction in RRC and release. These results suggest that dietary protein restriction does not directly affect the tubular capacity to generate and reabsorb free water. The hemodynamic changes seen in protein deprivation are not mediated by ADH and may be secondary to increased intrarenal angiotensin II.

摘要:
The authors describe a 51-year-old Japanese woman who developed nephrotic syndrome in association with a total hydatidiform mole. The nephrotic syndrome remitted completely following hysterectomy. A renal biopsy performed before the operation showed diffuse mesangial cell proliferation of a moderate degree, and thickened capillary walls with focal and segmental subendothelial deposits, as well as circumferential mesangial interposition. Occasional foci of the mesangiolysis were also observed. Immunofluorescence microscopy revealed granular staining of IgM along the glomerular capillary walls in a fringe pattern. A review of the literature revealed that this patient appears to be the first case of nephrotic syndrome associated with a total mole, although there have been two cases of nephrotic syndrome due to preeclamptic nephropathy associated with a partial or transitional mole.

摘要:
The authors present two cases of systemic blastomycosis successfully treated with fluconazole. In one case, the disease involved the respiratory tract, and the central nervous system was presumed to be involved. The second case consisted only of pulmonary blastomycosis. Both patients were treated with oral fluconazole 200 mg twice per day for 9 and 6 months, respectively. Treatment with this new triazole antifungal agent resulted in the complete resolution of the disease in both patients. They have remained asymptomatic for more than 6 months after the completion of therapy.

摘要:
Under the assumption that in some patients with refractory anemia with excess of blasts (RAEB), the abnormal clones might be less responsive to granulocyte colony-stimulating factor than normal clones, the authors tried alternation therapy with a recombinant form of this factor (rhG-CSF) and antileukemic agents in the treatment of two patients with RAEB in transformation. After repetition of the short-cycled alternation therapy, the hematologic findings of both patients were completely normalized and have remained so without any adverse side effects under the continuation of this therapy for more than 5 months. Judging from our clinical experience, the alternation therapy may be a new efficient therapeutic strategy for RAEB and some types of slowly progressive leukemia.

摘要:
Ocular toxicity is an uncommon complication of cytotoxic chemotherapy. Retinitis pigmentosa complicating cancer chemotherapy has not been reported. A patient with probable Usher's syndrome (congenital sensorineural deafness) had apparent acceleration of retinitis pigmentosa with blindness following cytotoxic chemotherapy for non-Hodgkin's lymphoma. Retinitis pigmentosa, a feature of Usher's syndrome, usually develops as a slowly progressive process. The rapid acceleration of retinopathy following tumor therapy suggests a possible relationship to the cytotoxic chemotherapy. Lymphocytes and fibroblasts from patients with Usher's syndrome are hypersensitive to the x-ray type of DNA-damaging agents. The DNA-damaging effects of chemotherapy may have accelerated the progression of retinitis pigmentosa in this patient.
