Premorbid personality in patients with uni- and bipolar affective disorders and controls: assessment by the Biographical Personality Interview (BPI).

The relationship between premorbid personality and subtypes of affective disorder was investigated by means of the Biographical Personality Interview (BPI) and by a self-rating scale. Interviewer and rater (BPI) were blind to diagnosis. A total of 52 patients with unipolar depression or bipolar II disorder (D/Dm), 32 bipolar-I patients (DM) and 39 control subjects (C) were examined. Expert rating of "typus melancholicus" features (BPI) were found to be more pronounced in D/Dm than in DM and C. "Typus manicus" features were also distinguished between both clinical groups, whereas anxious-insecure features were not significantly different between the groups of patients. In contrast to the expert-rated personality variants, self-rating of personality features did not reveal any significant differences between the two clinical groups. Potential sources of the discrepancies between the questionnaire data and the interview data are discussed. It is concluded that premorbid features of "typus manicus" and "typus melancholicus" predicted, respectively, a predominant manic and a predominant depressive course of an affective disorder.

Increased sensitivity of the inositol-phospholipid system in neutrophils from patients with acute major depressive episodes.

Evidence from in vitro and in vivo studies suggests that the therapeutic and prophylactic effects of lithium in recurrent affective disorders are due to an attenuation of the inositol-phospholipid (IPL) second messenger system. An increased sensitivity of this signal transduction system might therefore constitute a risk factor for affective illness. The extent of the agonist-induced release of intracellular Ca2+ (Ca2+ response) can be used as an indicator of the sensitivity of the IPL system. Using this paradigm, we have measured the agonist-induced Ca2+ response in neutrophils of 17 unmedicated patients who were experiencing an acute major depressive episode. The neutrophils were stimulated by the chemotactic peptide formylmethionylleucylphenylalanine, which activates the IPL system in the cells. The sensitivity of the IPL system in these patients was significantly greater (dose-response curve shifted to the left) compared with its sensitivity in healthy age- and sex-matched control subjects. The results indicate that acute episodes of major depression are associated with an increased sensitivity of the IPL system.

Health services delivery to students with special health care needs in Texas public schools.

A statewide survey of 2,875 Texas public school nurses was conducted to determine the characteristics, needs, and involvement of nurses in the health and education management of students with special health care needs (SSHCN). The 1,574 survey respondents (response rate = 55%) were primarily registered nurses (84%) with a mean of 8.6 years (SD = 7.1) of experience in the school setting. Respondents served 1.5 school campuses on average; the mean nurse-to-student ratio per campus was 1:728 (SD = 518). Respondents identified 106,650 SSHCN (6% of total enrollment). Asthma (47%), attention deficit disorder (26%), and seizure disorders (8%) were the most prevalent conditions encountered among SSHCN. Medication administration (54%), diapering (12%), and inhalation respiratory treatments (11%) were the most common of 48,569 health procedures delivered daily to SSHCN by nurses, clerical staff, assistants, and teachers. Parents were identified as the primary source of both child-specific health (70%) and training (68%) information in the school setting. Although nurses, of all school personnel, are likely best able to speak to the impact of a child's health impairment and needed school services, only 32% of respondents reported routine participation in special education eligibility evaluations and only 18% reported routine attendance at special education meetings for SSHCN. Moreover, 84% and 92%, respectively, reported discomfort at participating in special education eligibility evaluations and attending special education meetings.

A descriptive study of foot problems in children with juvenile rheumatoid arthritis (JRA).

In this study, we evaluated the feet of 144 consecutive children with juvenile rheumatoid arthritis (JRA) during a routine outpatient visit to discover patterns of foot problems. We found that all but nine subjects had at least 1 of 21 foot problems, categorized as inflammation, limitation of motion, and abnormal alignment. Overall, pronated rearfoot and midfoot were observed in 73% and 72% of JRA patients, respectively. Additionally, 36% had splayfoot, whereas 35% of subjects had ankle limitation of motion. Other common foot problems included pronated forefoot, rearfoot and forefoot synovitis, forefoot limitation of motion, and toe valgus. Significant differences in the occurrence of various foot problems were observed among JRA onset/course subgroups and were influenced by both age and disease duration. Specifically, subjects with polyarticular JRA had more forefoot limitation and toe valgus, whereas subjects with pauciarticular JRA had pronated forefoot more often. Ankle limitation of motion, although unrelated to the JRA sub-group, was related to the duration of JRA. Subjects with longer disease histories also had toe valgus more often. Conversely, forefoot limitation of motion seemed to be more a function of age than of disease duration. These results indicate that foot problems are common in the JRA population, and they underscore the need for thorough evaluation and physical therapy management.
