With a national trend toward decreased hospitalizations for high-risk childbearing women, home care and follow-up services have gained increased importance. The Quality-Cost Model of Nurse Specialist Transitional Follow Up Care is presented as a method to provide home care for high-risk pregnant women, specifically those whose pregnancies are complicated by diabetes mellitus. The model offers opportunities for intensive education, assessment, intervention, and support throughout the pregnancy and postpartum period. In addition, this model can potentially decrease the burden of care on the woman and her family by providing a comprehensive program of home care, follow up, support, and education. 相似文献

Emphysematous pyelonephritis and cystitis are both rare entities that have not been reported in children. The authors report an unusual case of a baby boy presenting with bilateral emphysematous pyelonephritis and cystitis associated with bilateral pelviureteric junction obstruction and urinary tract infection. 相似文献

In view of a possible clinical application of an isolated microvascular peritoneal flap, an anatomic study was performed in order to determine the peritoneal vascular territory of the deep inferior epigastric artery. For this, the deep inferior epigastric artery was injected unilaterally with Araldite in 30 embalmed cadavers and bilaterally with india ink in 15 fresh cadavers. In 70 percent of the embalmed cadavers, a constant pattern of three branches from the deep inferior epigastric artery could be identified. The peritoneal vascular supply is not derived solely from these three branches but also from multiple small branches sprouting directly from the main stem of the deep inferior epigastric artery and from segmental and muscular branches. Therefore, classification of peritoneal branches arising from the deep inferior epigastric artery seems to be of little clinical importance. In all cases, the india ink injected in the deep inferior epigastric artery colored a similar territory of the parietal peritoneum. Considering the magnitude of the peritoneal vascularization by the deep inferior epigastric artery, implementation of an isolated free or pedicled peritoneal flap seems to be possible. Such a microvascular peritoneal flap vascularized by the deep inferior epigastric artery may be used, for example, for reconstruction of mucosal defects in the head and neck region. 相似文献

We aimed to determine whether our results were any better or worse than other published reports and to examine the efficacy of the West Midlands Ambulance Service (WMAS) policy of applying cardiopulmonary resuscitation (CPR) and manual ventilation to all unwitnessed cardiac arrests in preference to immediate defibrillation. All cardiac arrests were studied from October 1994 to September 1996. In all unwitnessed arrests, crews undertook CPR and manually ventilated the lungs via a mask or an endotracheal tube with a bag and valve or a mechanical resuscitator using an FIO2 of 1 or 0.21 for at least 2 min before defibrillation was attempted. There were 3403 diagnosed cardiac arrests but, in these, the diagnosis was not certain. CPR and advanced life support (ALS) were applied in 3380 patients and return of spontaneous circulation (ROSC) was obtained in 554, giving a success rate of 16.4%. A total of 364 patients were accepted into hospital, 90 patients died in A&E but 274 patients were admitted to ICU/CCU. Seventy died within 24 h, 69 died after 24 h and 135 were discharged alive and well without cerebral damage. The final success to discharge rate was 49.27%. Of those discharged, 69 had a circulatory arrest period of more than 4 min but in only 10 was a bystander available to start CPR. The European Resuscitation Council Guidelines recommending immediate defibrillation for unwitnessed arrests are not supported by these results. The apparent lack of cerebral damage and the percentage success suggests that resuscitation considerations should be as brain orientated as they are heart orientated. The elapsed time periods reported challenge several shibboleths. 相似文献

Inhaled allergens, acting through IgE-dependent mechanisms, are important triggers of asthma symptoms and inducers of airway hyperresponsiveness and airway inflammation. The effect of anti-IgE recombinant humanized monoclonal antibody-E25 (rhuMAb-E25) on the provocation concentration of allergen causing a 15% fall in FEV1 (allergen PC15) during the allergen-induced early asthmatic response (EAR) was assessed in a multicenter, randomized, double-blind, parallel group study. Ten of 11 allergic asthmatic subjects randomized to receive intravenous rhuMAb-E25, 2 mg/kg on study day 0 and 1 mg/kg on Days 7, 14, 28, 42, 56, and 70 completed the study; nine received intravenous placebo. The allergen PC15 was measured on Days -1, 27, 55, and 77 and methacholine PC20 on Days -2, 42, and 76. rhuMAb-25 was well tolerated and only one patient (active group) was withdrawn because of a generalized urticarial rash after the first dose. Compared with baseline values (Day -1), the median allergen PC15 on Days 27, 55, and 77 were increased by 2.3, 2.2, and 2.7 doubling doses (delta log PC15/0.3) respectively with rhuMAb-E25 and -0.3, +0.1, and -0.8 doubling doses with placebo (p < or = 0.002). Methacholine PC20 improved slightly after rhuMAb-E25, this change becoming statistically significant on Day 76 (p < 0.05); no change was observed in the placebo group. Mean serum-free IgE fell by 89% after rhuMAb-E25 while there was no significant change after placebo. The inhibitory effects of rhuMAb-E25 on allergen-induced EAR suggest that it may be an effective, novel antiallergic treatment for asthma. 相似文献

We identified large-scale heteroplasmic mitochondrial DNA (mtDNA) rearrangements in a 50-year-old woman with an adult-onset progressive myopathy. The predominant mtDNA abnormality was a 21.2-kb duplicated molecule. In addition, a small population of the corresponding partially deleted 4.6-kb molecule was detected. Skeletal muscle histology revealed fibers that were negative for cytochrome c oxidase (COX) activity and had reduced mtDNA-encoded COX subunits. By single-fiber polymerase chain reaction analysis, COX-negative fibers contained a low number of wild-type or duplicated mtDNA molecules (ie, nondeleted). In situ hybridization demonstrated that the abnormal fibers contained increased amounts of mtDNA compared with normal fibers and that most of the genomes were deleted. We concluded that deleted mtDNA molecules were primarily responsible for the phenotype in this patient. 相似文献

OBJECTIVE: The purpose of this study was to review the literature relating to the impact of work and workplace hazards on pregnancy, as well as to provide suggestions to practitioners caring for working women. STUDY DESIGN: This study is a review of the literature to date. RESULTS: Studies examining the impact of work during pregnancy on perinatal outcome have failed to yield consistent findings. An increase in preterm births and low-birth-weight infants has been observed in women who work in adverse conditions or in jobs with known hazardous exposures. No adverse outcomes are seen in women with less strenuous jobs or in women who are able to modify their work activity. CONCLUSION: A careful workplace history should be taken by the obstetrician-gynecologist including level of activity, hazardous exposures, and ease of workplace modification. Women whose work requires prolonged standing or walking should be monitored carefully throughout pregnancy for evidence of intrauterine growth restriction or symptoms of preterm labor. The ultimate decision on continuation of employment during pregnancy should be made by the patient after careful counseling by her physician and discussions with her employer. 相似文献

Nationwide, 45 states issue health advisories for sport fish consumers. Chemical contaminants in some Great Lakes (GL) sport fish include compounds suspected of causing adverse reproductive and developmental effects. Although advisories to reduce consumption of contaminated fish, especially by women, have been issued by GL states (i.e., Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania, and Wisconsin) since the mid-1970s, little is known about advisory awareness and GL sport fish consumption in the general population. To estimate the prevalence of GL sport fish consumption and health advisory awareness, we conducted a population-based telephone survey of 8,306 adult residents of the eight GL states. We gathered information concerning respondents' demographic characteristics, fish consumption during the preceding year, and sport fish consumption advisory awareness. The survey response rate was 69%. GL sport fish were eaten during the preceding year by 8.4% -95% confidence interval (CI), 7.6-9.2- of adults in the GL states, approximately 4.7 million persons. Women accounted for 43.9% (CI,39. 4-48.4) of consumers. Although 49.9% of GL sport fish consumers were aware of a health advisory, awareness varied significantly by sex: 58.2% (CI, 51.7-64.7) of males and 39.1% (CI, 32.6-45.6) of females were aware. Using logistic regression, we found awareness associated with male sex -odds ratio (OR) = 2.3; CI, 1.5-3.5), white race (OR = 4.2; CI, 1.9-9.1), college degree (OR = 3.1; CI, 1.3-7.6), and consuming >=24 GL sport fish meals/year (OR = 2.4; CI, 1.4-4.3). Only half of GL sport fish consumers reported awareness of a health advisory concerning eating GL sport fish. Awareness was especially low among women, suggesting the need of targeted risk communication programs for female consumers. 相似文献
