Beta hemolytic streptococcus group G is increasingly being recognized as a cause of serious infections. We describe a patient with group G streptococcus septic arthritis of the right knee and osteomyelitis of the proximal tibia. Clinical details of…
A potassium hydroxide preparation is used to confirm the diagnosis of a superficial fungal skin infection. Adding black or blue-black ink to the potassium hydroxide solution highlights fungal organisms and distinguishes them from surrounding cellular…
Whether a vesicobullous disease is intraepidermal or subepidermal is often difficult to determine from the clinical examination. The Tzanck preparation can provide clues that aid in the diagnosis of a number of diseases. It is particularly helpful in…
Patients with scabies may present with urticarial, eczematous or excoriated papules, eczematous patches or, occasionally, nodules. It is often difficult to differentiate scabies from eczema, folliculitis, drug eruption or lichen planus. The…
Eight male rats previously trained to discriminate 2.0 mg/kg N-ethyl-3,4-methylenedioxyamphetamine (MDE) from its vehicle in a two-lever, food motivated task were utilized to characterize the stimulus properties of MDE. The 5-HT receptor agonists…
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…
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…
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)…
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…
A 68-year-old man with fever of undetermined origin (FUO) was admitted to the hospital. At laparotomy, a large multilobulated benign microcystic adenoma of the pancreas was removed. Fever resolved spontaneously after surgery. Although a wide range of…
Cervical spine fracture/dislocation is a potentially devastating injury that may be clinically difficult to diagnose. Therefore, a vast majority of trauma patients undergo cervical spine X rays when only a relatively small number of them will…
Cholesterol 7-alpha-hydroxylase catalyzes the rate-limiting step in the bile acid biosynthetic pathway. Regulation of this pathway is thought to occur solely as a result of a negative feedback control mechanism that is dependent upon the flux and…
Six squamous cell carcinomas of the vulva (SCV) were karyotyped in short-term culture and in early passages as established cell lines. Each tumor was cytogenetically distinct, contained multiple chromosome rearrangements, and was karyotypically…
Circulatory indirect calorimetry (CIC) is a potentially useful method to assess the energy requirements of critically ill patients. Unlike respiratory indirect calorimetry (RIC), which measures oxygen utilization from inhaled and exhaled gases, CIC…
This report reviews 1% episodes of klebsiella bacteremia in 194 patients during a 10-year period (1980-1989) in a community teaching hospital in the USA. The median age of patients was 70 years with a mode of 84 years. The prevalence was 0.76…
We report three cases of group B streptococcal endocarditis of the tricuspid valve. Two patients were intravenous drug abusers. In the literature review, and including our cases, ten patients had group B streptococcal endocarditis of the tricuspid…
Expression of myosin heavy chain (MHC) isoforms was studied in rat soleus (SOL) and extensor digitorum longus (EDL) muscles which regenerated in the presence or absence of innervation. Frozen sections of two 5 day denervated SOL and EDL grafts, two…
We studied the ontogeny of muscarinic depression in the developing rat visual cortex using carbachol (a nonhydrolyzable cholinergic agonist) application to neocortical slices obtained from four postnatal age groups: 9-10 days, 15 days, 30-40 days and…
1. Para-chlorophenylalanine (p-CPA), a competitive inhibitor of the serotonin (5-HT) synthesis enzyme tryptophan hydroxylase, was administered to rats at a dosage (100 mg/kg daily for 3 days) that depletes 5-HT. 2. Different groups of these rats were…
