State association-sponsored program for SBB candidates.

Concern about the closure of the only Specialist in Blood Banking (SBB) School in the State of Michigan prompted the Michigan Association of Blood Banks (MABB) to develop and administer a comprehensive series of lectures to meet the needs of technologists seeking SBB certification via the experiential route. The program consisted of more than 60 1(1/2)-hour lectures covering all aspects of blood banking (genetics, coagulation, immunology, blood group serology, blood collection and administration, and transfusion medicine) except infectious disease testing and management issues. The latter were presented during two free-standing one-day seminars (for which a fee was charged for those not registered for the lecture series). Educational techniques were covered in a self-study module. Two lectures were presented one morning each week from March through December, with no presentations during July. Lecturers were local volunteer experts, and detailed learning objectives were established for each topic. Each registrant was charged a nominal fee ($100 for MABB members; $150 for nonmembers). There were 32 registrants for the lecture series, with additional registrants for the seminars. Total revenue was $5,100, and expenses amounted to approximately $2,400, mostly for faculty honoraria and catering for the two seminars. The popularity of our program reflects the need for alternatives to formal SBB schools.

Characteristics of adopted juvenile delinquents.

There have been many reports describing the uniqueness of adopted children and adolescents' delinquent behaviors in terms of both their delinquent characteristics and courts' treatment of them. A total of 43 adopted juveniles, 32 extrafamilial (1.0%) and 11 intrafamilial (0.3%) adoptions were initially identified out of 3,280 juvenile delinquents. The adopted subjects were then compared with the demographically matched and offense matched nonadopted subjects. The family variables, such as marital and employment status of parents, were significantly different. However, there were only a few discernible trends, and in general there were no significant differences between the adopted and nonadopted juveniles in terms of their offense characteristics and dispositions.

Breast cancer in nonpalpable lesions: can mammographic parenchymal pattern improve the predictive value of biopsy?

The increasing number of women referred for surgical biopsy of nonpalpable breast lesions detected by screening mammography led to a retrospective review of all such cases from October 1, 1986 to September 30, 1990. There were 165 consecutive, wire-localized, excisional biopsies of radiographic lesions performed on 158 patients during this 4-year period. A positive (i.e., malignant) result was found in 16 patients (10%); all but one of these 16 patients had stage I disease at subsequent treatment. Examination of historical factors (age, family history, prior biopsy, breast symptoms) and mammographic factors (mass, microcalcification, irregular borders, new lesion, parenchymal pattern of increased fibroglandular density) revealed that no patient with a diffuse parenchymal pattern of increased fibroglandular density had a malignant diagnosis. This finding was statistically significant (P = 0.002) by chi-square analysis. This negative relationship of radiographic parenchymal pattern to early cancer in nonpalpable lesions is contrary to what one would expect, based on several reports in the radiology literature. Over one-third (36%) of the author's patients had the increased fibroglandular x-ray pattern, making this finding potentially important for surgeons evaluating the patient with a nonpalpable lesion detected by mammography.

The spouse: a factor in recovery after acute myocardial infarction.

Literature supports the concept that the response of a patient's spouse influences the recovery process of a patient after an acute myocardial infarction (AMI). This was a 6-month, longitudinal, descriptive study of 17 married couples in which one of the pair experienced his or her first AMI. The study examined the question: "Is there a relationship between the spouse's social support, family stress, marital satisfaction, and sexual comfort and the patient's recovery after AMI?" Data were collected at three times during the 6-month period after AMI. Results showed a significant relationship between the spouse's family stress, marital satisfaction, and sexual comfort and the patient's recovery. Also, a significant relationship was found between the spouse's sexual comfort and marital satisfaction. This was the first reported study that examined sexual comfort over time and investigated sexual activities other than intercourse.

An interactive perspective on the health beliefs & practices of rural elders.

1. In this study, major themes involving health were closely tied to an affective response of "feeling good" and cognitive appraisal of health status as "being able to function." 2. Rural elderly who participated in the study reported engaging in at least one activity to maintain their health and tended to rely on their own appraisal and resources to manage health problems. 3. Half of the participants indicated a need for services such as blood pressure and diabetic screening, health education classes on diet, cholesterol reduction, hypertension and diabetes management, new therapies in health care, and life management counseling.

Influence of clerkship structure and timing on individual student performance.

Student oral and written surgical clerkship performances may be related to the clerkship structure and the time of year the students rotate through the clerkship. The influence of calendar block, hospital site (university hospital, affiliated private tertiary-care hospital, and rural preceptor experience), and the mix of general surgical versus subspeciality rotations on oral and written student surgery clerkship scores was analyzed. Multivariate analysis of variance revealed significant differences in score for calendar block (p = 0.02) only; this difference resided in the written examination. The various combinations of rotations were not different from one another in terms of measured outcome.

[The significance of ungulocoriitis septica (traumatic) in the toe of the bovine claw].

Due to the specific anatomy at the toe of the claw, inflammation of the corium at this site is characterised by a rapid spread to the distal phalanx. Radiography is important for the diagnosis and essential for determining the prognosis. In the early stage of the condition, therapy consists of correct wound care and relieving the affected claw from weight-bearing by applying an orthopaedic shoe to the partner claw. Resection of the claw toe is indicated if there is evidence of osteolysis. The postoperative healing period frequently lasts more than two months; there is a tendency to hypergranulation. Deformation of the claw due to irregular horn growth following surgery may occur. Compared to the treatment by amputation, the economic life of the patient is longer following resection and there are no restrictions on use.

Improving access to pediatric health care in Mississippi.

Working under the Mississippi Postneonatal Death Impact Project, the Mississippi Chapter of the American Academy of Pediatrics, in conjunction with the State Department of Health, helped improve access to pediatric health care in Mississippi. This was accomplished by developing a statewide telephone information and referral service (telephone case management), enlisting primary care physicians to treat a limited number of children without specific compensation and staging a public awareness campaign. System barriers encountered were identified and interagency coordination and cooperation suggested. This effort could be easily replicated and expanded.

Do first- and second-year preclinical course scores predict student performance during the surgical clerkship?

The study proposed to determine if a preclinical basic science index comprised of anatomy, behavioral medicine, biochemistry, microbiology, pathology, pharmacology, and physiology courses or any one of these basic science courses would predict student performance during surgical clerkship. The basic science index demonstrated a correlation of 0.55 and 0.35 with the individual student's written and oral clerkship scores, respectively. A stepwise multiple regression using a backward stepping algorithm was applied; the dependent variables were oral and written clerkship scores, and the independent variables were the basic science courses. Microbiology, pathology, and physiology course scores were predictors of written score (R = 0.60). Pathology course scores were the sole predictor of oral score (R = 0.43). Medical student basic science performance was not a strong forecaster of performance on the surgical clerkship. The pathology basic science score was the only consistent predictor of performance on the written and oral evaluations given at the end of the clerkship.

Smoking patterns during cognitive performance.

Studies on the effects of smoking and performance in learning and memory tasks have followed one of two strategies: (a) either subjects are required to smoke at fixed intervals and/or rates, or (b) subjects are permitted to smoke freely in the absence of any monitoring or observation of smoking acts. The present studies allowed free smoking within a structured context, while exposed to intelligence test items for 30 seconds. Subjects were observed to vary their smoking acts (puffing, tapping) as a function of the temporal characteristics of the task. Subjects followed the same pattern across two independent studies. Such findings have clear implications for smoking studies since they indicate that how and why subjects smoke may (a) vary with context, and (b) affect different task inputs.
