Recently, several groups have published new information regarding the origins and structure of the vitreous humour, and the inner limiting lamina (ILL) of the retina. This short article provides an overview of this new information. It is proposed that vitreous proteins are derived from several different cell types with the posterior half of the non-pigmented ciliary epithelium being prominent in the expression of several connective tissue macromolecules. In addition, some basement membrane macromolecules are also expressed by the ciliary body and may subsequently be assembled on the surface of the Müller cells to form the ILL. New data suggest that the posterior half of the non-pigmented ciliary epithelium has substantial secretory activity and is likely to play a pivotal role in eye development.  相似文献

The use of the Bene-Anthony Family Relations Test is described and illustrated by three examples of child abuse. This test should be considered in the investigation of definite or suspected cases of abuse and as part of the preparation of court evidence.  相似文献

A baby with unilateral cleft lip, midline cleft palate and hypertelorism developed meningitis in the first 48 h of life. Examination of the nasopharynx showed a soft tissue mass, which was confirmed as a basal encephalocele by computed tomography. There was also congenital hydrocephalus and the corpus callosum was absent. Surgical treatment included repair of the anterior basal skull defect, repair of the lip and palate, and ventriculo-peritoneal shunt. There is currently evidence of developmental delay and right-sided visual impairment due to Morning Glory syndrome. This case demonstrates that basal encephalocele should be considered in any baby with midline facial deformity who develops meningitis.  相似文献

OBJECTIVE: The management of recent-onset rheumatoid arthritis (RA) is not well standardized. We conducted a survey of drugs prescribed to RA patients in Brittany at presentation and during the first 1 to 3 years of follow-up. METHODS: A cohort of 270 patients with recent-onset inflammatory joint disease was recruited between 1995 and 1997. The evaluation at presentation included a medical history, a thorough physical examination, and a standard battery of investigations. Follow-up at 6-month intervals was offered. At the last visit, between June and December 1999, a panel of five rheumatologists established that 98 patients had RA. RESULTS: At presentation, hydroxychloroquine and injectable gold were the most widely used second-line drugs, and only two patients were offered a combination of second-line drugs. At the last visit, the most commonly used drugs were methotrexate, injectable gold, and hydroxychloroquine (23, 23, and 21 patients, respectively); only three patients were on more than one second-line drug and 38 (38/98, 39%) patients were on glucocorticoid therapy. CONCLUSION: Rheumatologists in Brittany prefer monotherapy with hydroxychloroquine or injectable gold as the initial treatment. Later, they rely mainly on methotrexate, injectable gold, and hydroxychloroquine, often in combination with glucocorticoid therapy.  相似文献

With the increasing numbers of older adults, factors impacting the effectiveness of provision of health care must be addressed. The literature suggests attitudes, particularly those of nurses, impact health service provision. This article reports the outcome of a multicountry validation study of the Reactions to Ageing Questionnaire (RAQ). The RAQ measures attitudes toward personal aging and has been used in Australia for 5 years. This study was designed to determine whether the psychometric characteristics and norms of the RAQ identified for Australian nurses also apply to nursing samples in Sweden and the United Kingdom. Findings indicate the internal structure of the RAQ extends outside Australia, with similar factors appearing across the three countries. Ranges and standard deviations indicate the instrument is able to discriminate between respondents within each country. Cronbach's alpha coefficients were consistent across countries and fell in the moderately high range. The findings indicate the RAQ has many potential applications in attitude assessment and in providing direction for training designed to address attitudinal factors that may impact the effectiveness of nursing practice for older adults.  相似文献

BACKGROUND: Long-term success rates of smoking cessation programs for patients with schizophrenia are unknown. This study, conducted between June 2001 and November 2002, evaluated the rate of smoking cessation and reduction in patients with schizophrenia (DSM-IV) 2 years after they had participated in a smoking cessation study in order to determine whether subjects who significantly reduced smoking during the original trial resumed their previous level of smoking at 2 years. METHOD: Two years following a double-blind placebo-controlled trial of bupropion sustained release, 150 mg/day, added to cognitive-behavioral therapy for smoking cessation in patients with schizophrenia, subjects were interviewed, medical charts were reviewed, and carbon monoxide in expired air was measured. RESULTS: Seventeen of 18 subjects completed the follow-up assessment. More subjects were abstinent (22% [N = 4]) at the 2-year follow-up than were abstinent at the end of the trial (6% [N = 1]). Subjects who achieved significant smoking reduction during the trial were more likely to be abstinent at 2 years (4/7) than those who did not significantly reduce smoking during the trial (0/11) (chi(2) = 8.1, p <.005). Most subjects who achieved > or = 50% reduction in smoking at the end of the trial maintained at least that level of reduction at 2 years. Smoking reduction during the treatment intervention was correlated with smoking reduction at follow-up (r = 0.60, p =.01). CONCLUSION: The results from this naturalistic study suggest that behavior changes achieved in smoking cessation programs for patients with schizophrenia may be durable and may predict future smoking behavior. We conclude that further investigation into the relationship between smoking reduction and future smoking cessation in special populations is indicated.  相似文献

Atrial Myxomas are benign primary tumors of the heart, arising mainly from the left atrium. Clinical signs and symptoms produced by atrial myxomas may be non-specific or result in mechanical obstruction of cardiac function, arrhythmias, and embolization. The authors present a case of a 60-year-old woman who developed total left hemiparesis resulting from left atrial myxoma embolization causing complete occlusion of the right middle cerebral artery.  相似文献
