Alar fold resection in horses: 24 cases (1979-1992)

Between 1979 and 1992, the alar folds were resected bilaterally in 22 horses and unilaterally in 2 horses. Abnormal respiratory tract noise and exercise intolerance were the primary complaints prior to surgery. Significantly (P = 0.01) more Standardbreds underwent resection of the alar folds, compared with the number of Standardbreds in the hospital population during the same period. The alar folds palpated abnormally thick in 13 horses and normal in 11 horses. Temporary dilatation of the nares with mattress sutures or clips lessened the respiratory tract noise and improved exercise tolerance in all 8 horses in which the diagnostic test was performed. Manual elevation of the alar folds reduced respiratory noise in the 11 horses evaluated. Long-term follow-up evaluation by telephone was available for 14 horses. All surgical incisions had healed cosmetically. Respiratory tract noise was decreased, and exercise tolerance improved in 10 of 14 (71%) horses. Complete charted racing information was obtained for 16 horses. Fourteen horses started their first race a mean of 118 days (range, 13 to 321 days) after surgery. The mean number of starts after surgery was 51, with 14 of 16 (88%) horses starting more than 6 times after surgery. Of the 16 horses, 8 horses raced at least 3 times before and after surgery; 4 had improved racing performance, 2 had similar performance, and 2 had decreased performance. Five Standardbreds never raced, and 1 Standardbred raced once before surgery.(ABSTRACT TRUNCATED AT 250 WORDS)     

The lives of female physicians

Survey data from 113 female physicians, 634 male physicians, and 41 female dentists were compared. Instruments designed to assess work satisfaction, work stress, marital satisfaction, family competence, and psychiatric symptoms and treatment were used, thereby exploring important life domains concurrently. The results suggest that female physicians are much more like both male physicians and female dentists than anticipated. Generally, female physicians describe high levels of work satisfaction, moderate levels of work stress, average-to-high levels of marital satisfaction, and relatively low levels of psychiatric distress. Their lower levels of practice income remain something of an enigma as gender remains the most powerful predictor of income and is not replaced in statistical analyses by specialty, hours worked, or other significant variables. Finally, female physicians who find higher levels of satisfaction in work also report higher levels of marital satisfaction and fewer psychiatric symptoms. For these women, a highly satisfying medical career does not apparently need to be experienced at the cost of marital or personal distress.     

Efficiency of computed tomography in diagnosis of silicotuberculosis

Seventy-five newborns from multiple pregnancies with very low and extremely low birth weight are studied. 94% of the infants under 1000 g and 66% of those above 1000 g are born by vaginal way. Intrapartal asphyxia develop most often the second twins with birth weight under 1000 g--64.7%. These are the infants with higher morbidity: RDS--56.5%, IVH--100%. The survival rate of the twins of this group is notably lower than that of the infants from singleton pregnancies with equal weight and gestational age: 12.1% under 1000 g and 69% above 1000 g, against 38.3% and 77.9% respectively.     

Evolution of nursing at University Hospitals: depositions by nurses who worked during the seventies

This study is part of a more extensive project that proposes to recover significant aspects related to nursing care evolution from 1950s until 1990s. This study is developed through the technique of oral declaration by active and retired registered nurses, in the context of an university-hospital from S?o Paulo State. The present study emphasizes the outcomes referring to the 1970s. As result becomes evident the undertaken effort by nurses in the struggle for profession's recognition and prestige; intense and deep transformations related to nurse's new roles as leadership of nursing staff and member of medical team.     

Bullous urticaria pigmentosa

Urticaria pigmentosa is the most common manifestation of cutaneous mastocytosis. Three-quarters of all cases occur during infancy or early childhood. Occasionally, vesicles or bullae may appear in persons with urticaria pigmentosa. We describe an unusual case of bullous urticaria pigmentosa with prominent scalp involvement. Prognosis and therapy are reviewed.     

Transitioning to independence: challenges for young people with disabilities and their caregivers

For all teens, the process of moving from childhood to adulthood is challenging. For young people with disabilities, transitioning to independence presents even more challenges. Barriers to successful transition for young people with disabilities include low expectations by parents and other significant people in the community, lack of knowledge of existing career and vocational education services, and lack of self-advocacy skills. This article provides an overview of issues related to transitioning to adult independence and offers suggestions for assessment, planning, and intervention that can help nurses be effective partners with families and other caregivers in transition efforts. Nurses caring for children with disabilities can help families see strengths in their children and develop realistic, developmentally-appropriate expectations for skill development, attitudes, and behaviors that will promote self-sufficiency in adulthood. Nurses can help families think about possibilities for independence and refer families to community resources that can help young people with disabilities pursue postsecondary education, obtain and maintain jobs, and live independently.     

TGF-beta knockout and dominant-negative receptor transgenic mice

Use of homologous recombination and transgenic technologies have provided mouse models to study the physiological roles of the three mammalian TGF-beta isoforms, and their regulation in the context of the intact animal. Mice harboring null mutations for TGF-beta isoforms demonstrate that each exerts discrete nonoverlapping functions during development. TGF-beta1 null mice reveal a crucial role for this cytokine in modulation of the immune system, with evidence for altered development, activation and function of various immune cell populations. New approaches to tissue- and cell-restricted disruption of TGF-beta signaling pathways in transgenic mice carrying dominant-negative mutant TGF-beta receptors will be discussed.
