Risk factors for herpes simplex-induced keratitis: a case-control study.

Forty-two patients at three institutions were compared with control subjects with regard to the prevalence of risk factors for herpes simplex-induced keratitis (HSK) that have been postulated in the literature. The patients' average age was 46.3 years; their average age at the first episode of HSK was 41.

[Value of renal scintigraphy in the diagnosis of vascular complications of renal transplantation].

Nuclear medicine can make an efficient contribution to the diagnosis and monitoring of renal disease and to the assessment of therapeutic interventions in the field of renal transplantation. The new radio pharmaceutical MAG 3 labelled with 99mTc provides renal imaging of quality in patients with impaired renal function and enables quantitative evaluation of renal function. We report on radionuclide evaluation, with special emphasis on the analysis of the vascular component of the scintigram, in the different clinical situations (i.

Endocrine management of breast cancer.

Hormonal therapy for breast cancer began more than a century ago with the observation that bilateral oophorectomy caused tumor regression in selected premenopausal patients. In the first half of this century, besides extending ablation of ovarian function to photon irradiation, surgical adrenalectomy and hyophysectomy were introduced, and hormonal additive therapy was established. Regression rates for advanced breast cancer with all types of endocrine therapy at this point did not exceed 35%.

Effect of prolonged postischemic perfusion on neonatal hearts.

Recent research on myocardial preservation has emphasized the importance of events occurring early in the reperfusion period, which may be of less importance to myocardial outcome in the neonate. We therefore wished to study the contribution of prolonged postischemic perfusion. This situation may occur during repair of congenital heart defects when in an attempt to reduce the period of aortic cross-clamp, the surgeon completes right-sided repairs on a beating empty heart.

Painful caliceal calculi. The treatment of small nonobstructing caliceal calculi in patients with symptoms.

From 1984 to 1989 35 patients presented with uncharacteristic flank pain or recurrent urinary tract infections and small nonobstructing caliceal calculi. Thirty patients were treated; 13 with percutaneous stone extraction, 8 with extracorporeal shock wave lithotripsy, 3 with ureteroscopic stone manipulation and 2 by open surgery. Stone removal was successful in 39 patients and they were all relieved of their symptoms (86%).

Acute appendicitis in pregnancy: complications and subsequent management.

Objective: To establish guidelines for the management of a pregnancy that is complicated by acute appendicitis.

Design: Retrospective study.

Setting: University Hospital, Copenhagen, Denmark.

[Prognosis of surgery performed in premature infants with birth weights below 1500 gram].

On account of improved management in neonatal intensive care units, the survival rate is presently nearly 50% in babies with birth weights below 1,000 grams and 80% in the group with birth weights from 1,000 to 1,500 grams. A number of these babies require surgery, either for correction of congenital anomalies or for acquired necrotizing enterocolitis, which is an increasing burden in neonatal units. The present analysis of 24 babies weighing under 1,500 grams, operated on in the period 1981 to 1988 confirms that even extremely small babies tolerate the performed anesthesia and surgery well.

Assessment of voiding dysfunction in men with acute epididymitis.

Fifteen men with a recent attack of acute epididymitis were examined urodynamically and endoscopically after the symptoms had resolved. Thirteen of the 15 patients had abnormal voiding. Two patients had stricture formation in the posterior urethra, one had benign prostatic hyperplasia, one had bladder neck sclerosis, and 4 had detrusor-external sphincter dyssynergia.

Informational needs and selected variables in patients receiving brachytherapy.

The increasing use of brachytherapy in patients with cancer mandates that the informational needs of these patients are met. A nonrandomized sample of 22 patients undergoing brachytherapy participated in a study to determine (1) informational needs, (2) the degree to which patients prefer to be informed about and to participate in their medical care, and (3) the relationship between informational needs and selected variables. Most patients (86.

[The control of storage mites in the mycological laboratory].

Mycological cultures in the laboratory are threatened by storage mites who feed on fungi and cause contamination by transferring bacteria and fungi from culture to culture. To eliminate mites from fungal cultures without damage to the fungi themselves several chemical and physical procedures were tested. The following substances were added to Sabouraud glucose (2%) agar at concentrations of 0.

Safety and immunogenicity of multiple conventional immunizations administered during early HIV infection.

Twenty-one asymptomatic adults who had recently received multiple polysaccharide, live viral, and protein-derived vaccines were identified as being infected with human immunodeficiency virus (HIV). The mean subject age was 24 years (range 18-33); 20 of 21 (95%) were male. The mean T4 count was 523/mm3 with a mean T4/T8 ratio of 0.
