Impact of a preceptor education board and computer network to engage community faculty at Dartmouth Medical School.

In 1994, as part of the Generalist Physician Initiative of The Robert Wood Johnson Foundation, Dartmouth Medical School established two programs to support and engage community-based teaching. The Preceptor Education Board and Community Computer Network were established to support a network of community-based preceptors and to facilitate communication between course directors at the school and community-based teachers. The board's mission is to organize, develop, and support a network of community-based primary care faculty, and to create and review community-based curricula. Through the board, community faculty members have made substantial contributions to curriculum, evaluation, faculty development, governance, and financing in community-based teaching. The Community Computer Network provides hardware, software, network systems, and support. Course directors and students have reported improved community-based educational experiences as a direct result of the Network. These two initiatives are dynamic and effective ways to improve the quality of community-based education and preceptors' morale. These efforts have strengthened the community faculty and their connection to the academic medical center.

Referrals for depression by primary care physicians. A pilot study.

BACKGROUND: Communication between primary care physicians (PCPs) and mental health providers (MHPs) is integral to the management of depressive disorders. Our study investigated referrals from PCPs to MHPs in a rural research network. METHODS: From April 1997 to September 1997, 5 family physicians tracked 6 weeks of referrals for depression and non-mental health problems and assessed the outcomes of these referrals after 3 months. The referrals were characterized by the nature and extent of communication between the PCP and the MHP and by the effectiveness of the consultation. RESULTS: Sixty-seven patients (44 with non-mental health disorders and 23 with depressive disorders) were identified and followed. Analysis of the initial referral process showed that the referring physicians felt a greater sense of urgency for the referrals for depression. Written evidence of the referral in the patient's chart at the 3-month survey was more common for non-mental health disorders. CONCLUSIONS: This pilot study demonstrates that there are communication barriers between PCPs and their mental health colleagues. Enhanced communication might improve satisfaction with the referral process. The details of the referral process need further study.

Recommended specifications for new mammography equipment: report of the ACR-CDC Focus Group on mammography equipment.

The American College of Radiology has published a report that describes desirable features for new mammography x-ray units that will contribute to high-quality imaging. It encompasses all aspects of x-ray equipment performance including mechanical considerations, the x-ray tube focal spot and spectrum, generator performance, collimation, scatter rejection, and the automatic exposure control. The report is intended to provide guidance to equipment manufacturers and to purchasers of mammography systems with regard to basic performance levels that should be expected.

Canadian multicenter randomized clinical trial of chorion villus sampling and amniocentesis. chromosome mosaicism in CVS and amniocentesis samples.

Data on 1040 chorionic villus and 969 amniotic fluid samples were collected from women studied in the Canadian Multicentre Randomized Clinical Trial of Chorion Villus Sampling and Amniocentesis. Cytogenetic results were obtained from 98.0 per cent of chorionic villus samples and from 99.9 per cent of amniotic fluid samples. Level I mosaicism (a single cell with an abnormal karyotype) occurred frequently in both chorionic villus and amniotic fluid samples and appeared to have no clinical significance. Level II mosaicism occurred in 0.9 per cent of CVS mesenchyme and 1.5 per cent of amniotic fluid cultures and in general was not perceived to be of sufficient concern to warrant cytogenetic follow-up studies. Level III mosaicism was reported in 18 CVS cases (15 cytotrophoblast, 1 mesenchyme, and 2 with both cell methods) and in one amniotic fluid case. In all cases but one (fetus with trisomy 18), level III mosaicism was confined to the placenta. Maternal cell contamination occurring with a frequency of 6.4 per cent in the mesenchyme analyses was a concern. This study supports the final report of the Canadian Multicentre Randomized Clinical Trial of Chorion Villus Sampling and Amniocentesis. Cytogenetic analysis of chorionic villus samples appears to be an acceptable alternative to the analysis of amniotic fluid samples. However, because of mosaicism and maternal cell contamination concerns, the examination of both cytotrophoblast preparations and mesenchyme cultures from chorionic villus samples is recommended.

[Corneal changes in Scheie disease. (Mucopolysaccharidosis type I S) (author's transl)].

Bilateral keratoplasty performed on a 39-year-old patient with Scheie disease gave the opportunity to study the histological, histochemical and ultrastructural lesions of both corneas. The patient showed all the characteristics signs of Scheie disease with bilateral corneal opacities, thick face, synophrys, mitral and aortic valve stenosis, bilateral carpal tunnel syndrome, stiff joints, and was of normal intelligence. 24 hours urines revealed a marked excretion of mucopolysaccharides. Histology showed scarring of the superficial stroma. Histochemistry revealed an accumulation of acid mucopolysaccharides in the keratocytes throughout the stroma. Electron microscopy showed vacuoles or pleomorphic inclusions in the keratocytes compabible with abnormal lysosomes deficient in alpha-L-iduronidase.
