Physician demographics and the risk of medical malpractice.

Purpose: This study was undertaken to clarify which, if any, physician demographic characteristics are associated with an increased rate of medical malpractice claims.

Methods: We analyzed the malpractice experience of 9,250 physicians insured for at least 2 years from 1977 to 1987 in the state of New Jersey. After adjusting for years at risk, physician claims per year was categorized into low, medium, and high.

Update in biomedical visualization: the professional communicator's role.

Health science communications professionals span a broad range of disciplines, each bringing a distinctly different focus and set of cognitive skills to bear upon information technologies. Nowhere is this more apparent than in biocommunications service units and academic programs. Until now, most faculty from visually-based disciplines were rarely required to generate research or project contracts.

In vitro response of a human colon tumor xenograft and a lung adenocarcinoma cell line to alpha-difluoromethylornithine alone and in combination with 5-fluorouracil and doxorubicin.

We have investigated effects of alpha-difluoromethylornithine (DFMO), both as a single agent and in combination with 5-fluorouracil (5-FU) against a human colon tumor xenograft (T6) grown as primary tissue culture in serum-free medium and in combination with doxorubicin (DX) against a human lung adenocarcinoma cell line (A549). DFMO showed a dose-dependent growth-inhibitory effect against human colon tumor xenograft and lung adenocarcinoma cells. Growth-inhibitory activity of DFMO against T6 cells was reversed completely when the cells were treated simultaneously with putrescine (PU) (10(-6) M) and DFMO (10(-3) M).

Follicular development and oocyte maturation after stimulation with gonadotropins versus leuprolide acetate/gonadotropins during in vitro fertilization.

Follicular development and oocyte maturation were compared in 22 patients stimulated with human menopausal gonadotropins/human chorionic gonadotropin (hCG, group I) and in 52 women also treated with the gonadotropin-releasing hormone agonist (GnRH-a) leuprolide acetate (LA, group II). Suppression of endogenous leutinizing hormone (LH) surges by LA allowed delayed hCG administration, resulting in higher peripheral estradiol levels, more retrieved oocyte cumulus corona complexes, and greater numbers of cryopreserved embryos. Reduction in spontaneous LH surges in the GnRH-a cycles may have allowed time for larger follicular fluid (FF) volume accumulation during all phases of oocyte cumulus corona complex maturation, restoring synchrony between FF volume and oocyte cumulus corona complex maturity.

The diagnosis of dementia: demographic characteristics.

The demographic characteristics of 242 clinic outpatients evaluated for dementia were examined. Each individual received a comprehensive assessment of medical status, psychological functioning, and social abilities. Diagnoses were arrived at by consensus, and appropriate treatment plans and follow-up recommendations were generated, with comprehensive feedback provided to family members and other caregivers.
