A 52-year-old man was referred for evaluation of three mildly pruritic patches on his right lateral upper arm, left shoulder, and right posterior thigh. The lesions had been present for 4 years, and although itching had decreased, they had failed to…
Noninvasive diagnostic studies, i.e., sputum gram stain, sputum culture, blood culture and antigen detection assays will assist the clinician in the selection of initial antimicrobial therapy in some patients. These tests may be even more valuable in…
Based mainly on the simplicity of its calculation, the urea reduction ratio (URR) has been suggested as an alternative to urea kinetic modeling (Kt/V) as a measure of hemodialysis adequacy. However, recent studies have raised questions concerning the…
The authors identified the origin of a high-density artifact with mammography film. An acrylic ramp phantom (thickness, 0-7 cm) was used to create a continuously variable radiation exposure. A perturbation in the curve of optical density versus…
While patient care has been shifting to the ambulatory setting, the education of health care professionals has remained essentially hospital-based. One factor discouraging the movement of training into community-based ambulatory settings is the lack…
The current study has documented changes in the ultrastructure as well as in the intranucleolar distribution of rDNA and rRNA in RT4 (human transitional cell bladder carcinoma) cell nucleoli following a 3-h exposure to toxic doses of 50 microM…
Sepsis stimulates an increase in the number and activity of mononuclear phagocytes in systemic host-defence organs. The present study was conducted to define the ultrastructural and cytochemical characteristics of the mononuclear phagocytes that…
A prospective, descriptive study is reported on the use and success of ultrasound-assisted internal jugular central vein catheterization (CVC) in the emergency department (ED). In patients not in cardiac arrest who had an indication for internal…
Cell-matrix interactions are important in the development of the avian cornea. Type VI collagen is present within the periocular mesenchyme prior to the migration of cells into the corneal stroma and is abundant in the mature stroma. Whether the…
Outcome data were collected on 239 patients who underwent endoscopic release of the transverse carpal ligament. The procedure was performed on 333 hands in 239 patients. All patients had failed to respond to nonoperative management for carpal tunnel…
BACKGROUND. Although many treatment modalities have been described for xanthelasma palpebrarum, no single technique has emerged as dominant. OBJECTIVES. Our purpose was to review the various therapeutic modalities for xanthelasma anti to assess the…
Purpose. To evaluate the post-lumpectomy treatment of a nonpalpable, stage 1, T1b tumor, mammographically detected, in a 74-year-old woman without comorbidities. Methods. A Markov process, through 120 monthly cycles, was used to model patient…
The gene encoding cholesterol 7alpha-hydroxylase (CYP7A), the rate-limiting enzyme in bile acid synthesis, is transcriptionally regulated by bile acids and hormones. Previously, we have identified two bile acid response elements (BARE) in the…

BACKGROUND: Intense activation of the sympathetic nervous system or administration of high concentrations of catecholamines diminishes myocardial contractility and produces infarct-like lesions throughout the heart. This study was conducted to…
Amiloride is an inhibitor of urokinase plasminogen activator (uPA), an essential component of the plasminogen/plasmin enzyme system. Inhibition of uPA prevents the conversion of plasminogen to tumor cell surface bound plasmin which is required for…
Serum albumin is a poor nutritional marker, but it is a good prognostic marker correlating with morbidity and mortality. However, IV albumin administration in hypoalbuminemic patients does not decrease tube feeding-associated diarrhea or intolerance,…
Infections caused by M. pneumoniae, C. pneumoniae, and Legionella spp. are important causes of community-acquired pneumonia (CAP). In the past decade, considerable new information has come to light concerning these organisms. Despite this, debate…
Primate hands can be classified into two broad categories on the basis of ray proportions and other features. Ectaxonic hands are characterized by a longer fourth ray and are found in most strepsirhines. Most haplorhines possess mesaxonic hands which…
The effects of varying doses of nicotine infusion upon spontaneous (basal) and subsequent potassium chloride-stimulated dopamine and 3,4-dihydroxyphenylacetic acid (DOPAC) output from superfused corpus striatal tissue fragments of male rats were…
In the present report, the peptides arginine vasopressin (AVP), oxytocin (OXT) or their respective antagonists were infused bilaterally into the olfactory bulb to assess their effects upon recognition responses. Recognition responses were determined…
Previous research has demonstrated that the antinociceptive efficacy of opioids decreases with advancing age. This study utilized radioligand binding techniques to determine if this decline is due to a change in the receptor density (Bmax) and/or…
BACKGROUND: Consultation and referral are essential components of the practice of primary care. Despite this, little is known about the factors that contribute to the success of a referral. We examined the short-term outcomes of communication between…

Tamoxifen (10 pg/ml) was infused directly into superfused striatal tissue fragments of ovariectomized rats for a 50 min period. Immediately following the termination of tamoxifen there was a significant increase in dopamine output compared with…
A 39-year-old man presented with a 2-cm, mildly tender mass in the right breast of many years' duration. Microscopic examination showed a syringocystadenoma papilliferum. Because of its location in the breast, we studied the lesion for…
Information derived from application files of potential cadaveric donors to our body donation program from the period of 1978-1993 was entered into a customized database to assess the characteristics of people contributing to such a program. A total…
