Nonstandard Programs: the University of Pittsburgh Medical Center's next frontier in graduate medical education.

The University of Pittsburgh Medical Center has seen continuous growth in the number and types of graduate training programs not accredited by the Accreditation Council for Graduate Medical Education (ACGME), the American Board of Medical Specialties, or the American Osteopathic Association. For the purposes of ensuring best educational products and of controlling unrecognized competition with our accredited programs, a sequential process of centralized oversight of these nonstandard programs was undertaken. The first step involved programs whose fellows were hired and tracked like accredited fellows (i.

Dysregulation of neurosteroids in obsessive compulsive disorder.

Alterations in hormone concentrations, including adrenocorticotropin, corticotropin releasing hormone, and cortisol have been reported in patients with obsessive compulsive disorder (OCD). Dehydroepiandrosterone (DHEA) and its sulfated metabolite, DHEA-S, have not been assessed in patients with OCD. We report 24-h serum DHEA, DHEA-S, and cortisol concentrations in a young man with OCD and 15 healthy young men.

Influence of DHEA administration on 24-hour cortisol concentrations.

DHEA is marketed and readily available as a daily nutritional supplement to counteract the effects of aging. The effect of DHEA administration on 24-hour plasma cortisol profiles has not been investigated. In this single-blind placebo-controlled crossover study, the effect of DHEA administration on cortisol concentrations was evaluated in healthy older women and men.

Sex differences in the pharmacokinetics of dehydroepiandrosterone (DHEA) after single- and multiple-dose administration in healthy older adults.

The pharmacokinetics of exogenously administered DHEA have not been well characterized despite its increasing use in therapeutic and research investigations. The purpose of this study was to evaluate the pharmacokinetics of DHEA and its sulfated metabolite (DHEA-S) after single- and multiple-dose oral administration of DHEA 200 mg. Healthy older adult volunteers (7 women, 6 men) ages 65 to 79 years were studied on five visits separated by 1 week.

Alprazolam increases dehydroepiandrosterone concentrations.

The gamma-aminobutyric acid (GABA) agonist alprazolam is known to decrease adrenocorticotropic hormone and cortisol concentrations. Dehydroepiandrosterone (DHEA) is secreted synchronously with cortisol by the adrenal glands and demonstrates diurnal variation. The major objective of this study was to determine whether alprazolam affects concentrations of DHEA and DHEA-S, the sulfated metabolite.

Correlates and prevalence of benzodiazepine use in community-dwelling elderly.

Objective: To describe the prevalence of benzodiazepine use, sociodemographic and physical health factors associated with use, dosages taken, and directions for use among individuals aged 65 years and older.

Design: Cross-sectional analysis of baseline data from the community-based, prospective observational Cardiovascular Health Study.

Patients/participants: Medicare eligibility lists from four U.

Alprazolam in young and elderly men: sensitivity and tolerance to psychomotor, sedative and memory effects.

This study was designed to determine whether age influences sensitivity to alprazolam and/or rate of acute tolerance development to the effects of alprazolam. Three treatments were each separated by 4 weeks. Twenty-five young (ages 22-35) and 13 elderly (ages 65-75) men received 2 mg of alprazolam/2 min i.

Didactic value of the clinical evaluation exercise. Missed opportunities.

The clinical evaluation exercise (CEX), a direct observation of trainees' clinical skills, is a common method of house officer evaluation. During our studies of its reliability, the extent of the CEX's didactic value surfaced. This brief report describes the amount of information passed from the evaluator to the house officer in 73 CEXs.

Hepatic myelopathy. Case report with review of the literature.

Hepatic myelopathy is a rare complication of hepatic insufficiency, causing progressive spastic paraparesis. There are few reports detailing the clinical and diagnostic aspects of this uncommon cause of neurological deterioration in patients with liver disease. Early recognition of this disorder will become more important as patients with liver disease survive longer due to medical advances, including liver transplantation.

Oral administration of micronized progesterone: a review and more experience.

Historically, oral progesterone has been regarded clinically ineffective because of its poor absorption and rapid clearance. Recent evidence suggests that an oral micronized form of natural progesterone is readily absorbed, produces luteal phase serum concentrations, provokes an end-organ response, and has no detrimental effect on the lipoprotein profile. Thus it is considered by many to be an attractive alternative to synthetic progestin.

Triazolam pharmacokinetics after intravenous, oral, and sublingual administration.

This study was designed to evaluate the relative and absolute bioavailability of triazolam, 0.25 mg, after the administration of the marketed oral tablet and a sublingual prototype wafer; an intravenous dose was used as a reference. Twelve men were evaluated in a three-way crossover study; study days were separated by 1 week.

Pharmacokinetics and pharmacodynamics of triazolam after two intermittent doses in obese and normal-weight men.

This study was designed to determine whether differences in alpha-1 acid glycoprotein and free drug concentrations result in an altered response to triazolam. Twelve normal-weight and 12 obese adult male subjects received intravenous doses of triazolam, 0.5 mg, on two occasions separated by 1 week.

Orally administered progesterone enhances sensitivity to triazolam in postmenopausal women.

An endogenously formed metabolite of progesterone, 3 alpha-hydroxy-5 alpha-dihydroprogesterone (3 alpha-OH-5 alpha-DHP) modulates the gamma-aminobutyric acid receptor complex and plays a physiologic role in brain excitability regulation. On the basis of in vitro observations of 3 alpha-OH-5 alpha-DHP-enhanced [3H]flunitrazepam binding, we investigated the potential clinical effect of coadministering oral progesterone and triazolam. Sixteen postmenopausal women were randomly assigned to receive either intravenous triazolam plus oral progesterone 300 mg (TRZPROG) or intravenous triazolam plus oral placebo (TRZ).

Design and pharmacodynamic evaluation of novel dual release formulations of triazolam.

Triazolam is an effective hypnotic that can cause amnesia and psychomotor performance decrements, particularly after a 0.5 mg dose. Previous pharmacodynamic studies suggested a relationship between these effects and triazolam plasma concentration.

The inter-rater reliability and internal consistency of a clinical evaluation exercise.

Objective: To assess the internal consistency and inter-rater reliability of a clinical evaluation exercise (CEX) format that was designed to be easily utilized, but sufficiently detailed, to achieve uniform recording of the observed examination.

Design: A comparison of 128 CEXs conducted for 32 internal medicine interns by full-time faculty. This paper reports alpha coefficients as measures of internal consistency and several measures of inter-rater reliability.

Practical problems of conducting patient-satisfaction surveys.

Objective: Patient-satisfaction surveys have been used frequently to assess the humanistic behaviors and skills of internal medicine housestaff. In conducting their first such survey, the authors found that many practical problems affected the progress and outcome of the project. This discussion of the authors' experiences is intended to be helpful to others considering patient-satisfaction surveys as part of their housestaff-evaluation process.

The intravenous pyelogram in acute pyelonephritis.

In a cohort of 67 otherwise healthy patients with acute pyelonephritis that was severe enough to warrant hospitalization and uroradiography, 8% had a genitourinary abnormality that influenced management. Consequently, over 90% of patients had studies that did not alter their care. In an attempt to identify clinical clues that might increase specificity without compromising sensitivity of the intravenous pyelogram in acute pyelonephritis, only the fever curve was statistically useful.

Pyoderma gangrenosum with myelofibrosis.

Pyoderma gangrenosum is a papulovesicular skin disorder commonly associated with underlying systemic disease, but rarely with the myeloproliferative syndromes. A case of rapidly progressive pyoderma is cited in a 77-year-old white man who had no other evidence of disease aside from macrocytic anemia. Bone marrow biopsy revealed proliferation of fibroblasts and a dense reticulin network consistent with myelofibrosis.
