An unusual case of giant scrotal hernia is presented. Hernias of this magnitude are extremely rare, even in underdeveloped countries, and their repair is challenging to the surgeon and stressful to the patient. Only a few case reports on the use of…

The present study was designed to determine whether the diminution of growth hormone (GH) secretion that occurs in obese Zucker rats is related to alterations of GH-releasing factor (GRF) or somatostatin (SRIF) pituitary binding sites. Cold…

This report is a cytometric study of the female Syrian hamster gallbladder epithelium following 1-, 2-, and 3-month administration of female sex steroids. Nulliparous, multiparous, young, old and pregnant hamsters were used in this study. A 1 month…

A 15-year-old boy with acute lymphoblastic leukemia (ALL) developed disseminated fusarium infection with meningoencephalitis following a contaminated skin wound. With antifungal therapy, the cutaneous lesions cleared but central nervous system (CNS)…

A patient with neonatal glycine encephalopathy who had severe neurologic retardation, spasticity, and seizures died at 17 years of age. Glycine concentration was markedly elevated in brain tissue, especially in the cerebellum. Neuropathologic study…

The secretion of growth hormone (GH) is impaired in the genetically obese Zucker rat where GH gene expression and plasma GH levels are depressed; however, the underlying mechanism of this abnormality remains unclear. We have evaluated the potential…

Levels of pituitary growth hormone (GH) messenger RNA (mRNA) were compared in groups of genetically obese (fa/fa) and lean (Fa/-) littermate male Zucker rats at four different ages, 3, 5, 9, and 11 weeks, in order to determine the earliest age at…

In order to investigate whether the impaired GH secretion associated with obesity is due to a pituitary disorder we studied GH mRNA levels by in situ hybridization in genetically obese and lean Zucker rats. The levels of GH mRNA were at least two…

In order to investigate whether the impaired GH secretion associated with obesity is due to a pituitary disorder we studied GH mRNA levels by in situ hybridization in genetically obese and lean Zucker rats. The levels of GH mRNA were at least two…

Objective: To determine the effect of age on the response to anti-arrhythmic drugs. Design: Randomized controlled trial comparing particular drugs. Setting: Multi-institutional (The Cardiac Arrhythmia Suppression Trial, CAST). Participants: 2,371…

We describe a normal pregnancy that was conceived less than 3 weeks following curettage for a blighted ovum. A delay between curettage and subsequent pregnancy is often recommended. Evidence supporting such a delay is examined.

Metolazone-induced acute pancreatitis and hypercalcemia are described in a 58-year-old woman with severe congestive cardiac failure. Her symptoms and laboratory abnormalities rapidly resolved upon discontinuation of metolazone. Both clinical and…

The aim of this study was to examine: (1) whether long-term potentiation (LTP) can be induced in slices from adult rat visual cortex under conditions where inhibition is not antagonized, and (2) the role of N-methyl-D-aspartate (NMDA) receptors in…

The paleopathological study of human osteological remains from the site of Semna South, of northern Sudan, revealed that about thirteen percent of this ancient Nubian population had diffuse idiopathic skeletal hyperostosis (DISH). As in modern cases,…

Two models of infant incubators were studied to determine the strength of the magnetic field generated by the heater and fan motors. Measurements were taken at intervals along the center line of the incubator. The results show that fields greater…

Fortunately, posterior instability of the shoulder is a relatively uncommon occurrence in the athlete. Acute traumatic posterior dislocations can be readily managed by conservative measures. Recurrent posterior subluxation, however, represents a more…

This prospective study was designed to (1) test the hypothesis that the majority of families of newly dead infants in a tertiary neonatal intensive care unit would consent to their infants' being intubated for teaching purposes, (2) determine factors…

Due to the curved path they follow, the visual callosal projections to areas OC1 and OC2 of the rat visual cortex have been inaccessible to studies using brain slices. In this paper we describe a new slice preparation in which a curved cutting blade…

A major finding in the visual plasticity literature is that visual deprivation is effective only during an early 'sensitive' period, which is lengthened by dark rearing. Unresolved is whether the visual cortex is in a normally plastic state prior to…

Purpose. To investigate further the psychometrics of a class-ranking model in which a weight of one-third was assigned to performance measures in basic sciences and a weight of two-thirds to ratings on six core clerkships. Method. The first part of…
