We used genetically heterogeneous HS mice to investigate the effects of drugs that alter brain concentrations of serotonin on cocaine-induced convulsions and lethality. The racemer of fenfluramine, which increases synaptic serotonin, was…
Staphylococcus epidermidis septicemia from a urinary source is rare. Two male patients had septicemic shock caused by S epidermidis urinary tract infection. Both patients had recently had indwelling urethral catheterization during severe illness.…
We describe four patients who had seizures while receiving ofloxacin; no other causes were evident. Common factors among all patients included advanced age and use of a high-dose regimen. The renal insufficiency of three patients and the timing of…
1. Male Sprague-Dawley rats were trained to discriminate 0.4 mg/kg nicotine subcutaneously administered from its saline vehicle in a food-motivated operant discrimination task. Once trained, the discriminative performance was observed to be…
OBJECTIVE. Sclerosing lobular hyperplasia is an infrequent benign lesion of the breast, defined as prominent hyperplasia of the lobules with sclerosis of the interlobular stroma. It commonly presents as a tumorlike mass clinically. Sclerosing lobular…
A MTT/formazan assay was used to evaluate the antitumor activity of vitamin C (Vit C), vitamin K3 (Vit K3), or vitamin C:vitamin K3 combinations against a human prostatic carcinoma cell line (DU145). Both Vit C and Vit K3 alone exhibited antitumor…
This study was undertaken to determine whether endothelium-derived relaxing factor (EDRF) modulates the pulmonary and systemic hemodynamic responses to massive sympathetic nervous system (SNS) activation and, in so doing, also modulates the degree of…
One group of heterogeneously bred HS mice was assigned to test coadministration of the selective D1 antagonist SCH 23390 with a dose of cocaine (95 mg/kg) that was observed to produce 80% lethality, whereas a second group was tested by cotreatment…
A 3-year-old girl with rhizomelic chondrodysplasia punctata (RCDP) had severe micrencephaly but a normal gyral pattern, neuronal density, and cortical cytoarchitecture. The white matter was diffusely decreased in mass but normally myelinated. There…
Determination of the relationship between silicone breast implants and rheumatologic disease requires comprehensive analysis of large numbers of individuals, both with implants and without. Techniques of history taking and physical examination,…
In a retrospective study, the first 301 patients who had laparoscopic cholecystectomy (LC) in a university-affiliated community hospital were compared with a historical matched control group of patients who had open cholecystectomy. The patients who…
Reduction mammaplasty is usually performed to relieve painful symptoms and physical signs of macromastia. Justification for reduction mammaplasty should be based on the probability of relieving these clinical signs and symptoms. This retrospective…
The effects of a deficiency of neurotrophin-3 on spinal motor neurons were assessed by determining the number of myelinated nerve fibers in lumbar ventral spinal roots of mice with a deletion in the neurotrophin-3 gene. Few or no small-caliber…
The primary care physician should be aware of recurrent corneal erosion, a condition that is quite common but is often misdiagnosed, Most cases are a result of minor corneal abrasion, after which the corneal epithelium undergoes a cycle of breakdown…
This study examines the recognition and treatment of emotional distress in physically healthy primary cave patients who perceive themselves to be in fair or poor physical health. Patients (N = 892) from three private primary cave practices completed…
The vertebrate reticular formation, containing over 30 nuclei in mammals, is a core brainstem area with a long evolutionary history. However, not all reticular nuclei are equally old. Nuclei that are widespread among the vertebrate classes are…
OBJECTIVE: To compare gastric pH control using intravenous famotidine as a primed, continuous infusion versus intermittent infusion. METHODS: In a prospective, double-blind study, 40 ICU patients at risk for stress ulceration were randomly assigned…
This article presents the editor's introduction to the article "Reading and Evaluating Qualitative Research Studies," by N. C. Elder and W. L.Miller, published in this issue of "The Journal of Family Practice." In qualitative research, the results…
This article examines self-reports of psychological interventions to patients with mental health problems by family physicians. Primary care patients completed a mental health screening form immediately prior to their medical visit. Results were…
1. The premorbid behaviors produced by the administration of cocaine, ethanol, their combination, as well as a metabolite produced by their co-administration, viz. cocaethylene, were defined, determined and quantified in the HS strain of mice. 2. The…
Background: Percutaneous endoscopic gastrostomy (PEG) is a safe access procedure for enteral nutrition. The purpose of this investigation is to identify predictive factors for early mortality after PEG. Methods: A retrospective review of the hospital…
The Cardiac Arrhythmia Suppression Trial (CAST) database was analyzed with a Cox proportional hazards regression model to predict the mortality of patients with very poor left ventricular systolic function (ejection fraction \textless or = .20).…
A 65-year-old male was found to have hepatic portal venous gas (HPVG) by computed tomogram secondary to ischemic bowel. Despite aggressive surgical and antibiotic treatment, the patient died within 12 hours. Portal pyelophlebitis, when identified by…
Autosomal dominant polycystic kidney disease (ADPKD), the most common inherited disorder in this country, is more than just a renal disease. Major extrarenal sites are the cardiovascular system, liver, and GI tract. The most devastating…
H-2 nuclear magnetic resonance (NMR) spectra were obtained at 30.87 MHz for 8% (w/v) aqueous dispersions of mixtures of bile salts (MBS), mixed intestinal lipids (MIL; myristic acid, monomyristoylglycerol dimyristoylphos-phatidylcholine = 5:1:1), and…
2H nuclear magnetic resonance (NMR) spectra were obtained at 30.87 MHz for 8% (w/v) aqueous dispersions of mixtures of bile salts (MBS), mixed intestinal lipids (MIL; myristic acid, monomyristoylglycerol, dimyristoylphosphatidylcholine = 5:1:1), and…
1. This study examined the ability of pentobarbital to inhibit NMDA and kainate-stimulated [3H]noradrenaline ([3H]NA) overflow in rat brain cortical slices. 2. Pentobarbital inhibited NMDA-evoked [3H]NA overflow at 100 microM and greater and…
Morphometry and oxidative capacity of slow-twitch (type I) and fast-twitch (type IIa and IIb) muscle fibers obtained from vastus lateralis needle biopsies were compared between younger (21-30 yr) and older (51-62 yr) normal fit (maximal O-2 uptake =…
S46, a monoclonal antibody (mAb) specific for the SM-1 and SM-2 isoforms of avian slow myosin heavy chains (MHC), was used to study the earliest stages of development of intrafusal fibers in muscle spindles of the rat hindlimb. Spindles formed only…
We report a case of biopsy-proven orbital lymphangioma with contiguous spread intracranially in a 14-year-old boy. The patient had a history of congenital orbital lymphangioma and hydrocephalus. Multiple functional and cosmetic periorbital surgeries…
A survey of 53 university and community hospitals revealed that 73% of the institutions had no standard policy for the replacement of triple-lumen catheters (TLCs). Since the maintenance of a TLC in place for a prolonged period may lead to infectious…
