Subcapsular liver hematoma is a rare and severe complication of pregnancy. This event is already known to have a poor maternal and foetal prognosis. The authors report a case of spontaneous rupture of subcapsular hematoma of the liver in 40 year old multiparous. Confirmation of diagnosis is obtained by abdominal echotomography or TOM. The surgical treatment of this hematoma joints the traumatic surgery of the liver. In every case foetal extraction by cesarean section constitutes the first therapeutic procedure. 相似文献

Primary renal non Hodgkin lymphoma is rare and unusual because the renal parenchyma does not have lymphatics. We report a case of bilateral primary lymphoblastic T lymphoma presenting with renal insufficiency in a 14 year old girl. We discuss clinical, pathological particularity and prognosis. 相似文献

PURPOSE: Retinal detachment is a rare but potentially blinding disease. Incidence of retinal detachment is stable in France, in spite of argon laser prophylaxis. METHOD: We have performed a prospective study on 100 patients with reghmatogenous, idiopathic retinal detachment. RESULTS: Functional signs were carefully recorded in 89% of cases. Vitreous signs were frequent (85%) mostly black points (67% of cases) myodesopia (32% of cases) floating images (14% of cases) black stains and filaments (11% of cases). Phosphens were recorded in 45% of cases and described as flashes of lightning in 30% of cases. Macular detachment was significantly more frequent among patients consulting after retinal signs appeared. CONCLUSION: Our study shows the frequency of functional signs in retinal detachment disease for rapid take over of these patients. 相似文献

This article presents currently known attempts, settings and implementation strategies for workplace health promotion with a remarkable impact for an effective prevention of work-related musculo-skeletal disorders. Internationally accepted measurement outcomes for effcasy and efficiency used in such programs will be discussed to develope quality criterias for the phases planning, implementation and evaluation. 相似文献

基于LMS回归的一步M估计与加权最小二乘估计 总被引:1,自引:0,他引:1
探讨在GM假设条件不满足情况下对线性回归模型的稳健估计方法。方法:介绍了估计的稳健性尺度和有效性的概念,采用基于LMS估计的M估计及加权最小二乘估计做稳健回归。结果:通过对一个模拟数据的分析,说明这两种稳健估计结果均优于经典的M估计及LS估计。结论:本文介绍的两种估计方法同时具有较高的稳健性及有效性,并可作近似的稳健推断。 相似文献

The ambident nucleophilic nature of the sodium salts of 2(1H)-qunioxalinone (2) and the phthalazinedione (3) has been realized from their alkylation with 2-(2-chloroethoxy)ethylacetate (1) to afford 1-[2-(2-acetoxyethoxy)ethyl]-2(1H)-quinoxalinone (8) and 2-[2-(2-acetoxyethoxy)ethoxy]qunioxaline (9) as well as 10 and 11, respectively. The corresponding derivatives 12-15 were similarly prepared by the alkylation of the unnatural bases 4-7 with 1. Treatment of the alkylated derivatives 8-15 with methanolic ammonia solution (1:1) at room temperature gave the corresponding hydroxyalkyl derivatives 16-23. The site of the alkylation was deduced from the spectral characteristics of the products. The activity of compounds 16-22 against Hepatitis B virus (HBV) in HepG2 cell has been tested. Some of the compounds showed high viral replication inhibition with low cytotoxicity. 相似文献

STUDY OBJECTIVE: To examine the impact of non-fatal war related injuries on physical disability in a group of war wounded civilians and to assess their needs. DESIGN: Cross sectional study. Home interviews were conducted using a structured interview schedule around one month after the injury, to assess impairments, disabilities, and needs. STUDY POPULATION AND SETTING: War wounded persons in towns and villages in South Lebanon during the attack "Grapes of Wrath" in 1996. RESULTS: The majority of the study population were young and in their productive age, mostly injured in the street or while hiding in open shelters. Around half of the injuries resulted in impairments, but, there were no age, gender or geographical differentials by severity of impairment. Almost one third (29%) of the students enrolled in schools at the time of the injury reported failure to continue their education and 42% of the working members lost their jobs with no potential for 34% of them to resume their former jobs. The impact of the injury on impairments, motor disabilities and physical independence was highest for injuries to the lower limbs (age and sex adjusted risk ratio (RR) 1.62, 95% confidence intervals (CI) 1.25, 2.10; 2.98, 95% CI 2.09, 4.23; and 2.13, 95% CI 1.39, 3.27, respectively). Despite the acute and early relief services provided by all those concerned at the time of the injury, when asked about unmet needs, the majority of the impaired (66%) reported the need for additional services, mostly medical in nature. The degree of disability was a salient factor for the need for rehabilitative services but not for medical services. CONCLUSIONS: The chronic and diverse needs of people with war injuries are often neglected and underestimated by the governmental institutions and relief agencies. Research funds as well as services should be allocated to tackle the long term and continuous health and social needs of those injured and their families. 相似文献

An experimental study evaluated the effect of various surgical procedures on maxillary growth. Raising and excision of palatine muco-periosteum did not modify facial or palatine growth. Resection of the bony palate showed the non-essential nature of the medial palaxine suture during normal growth, even in the transverse direction. Coagulation of the two posterior palaxine arteries disturbed palaxine growth, but ligature of the external carotid artery failed to alter facial growth. Several tests were carried out to determine the importance of functional matrices: excision of facial nerve trunk did not affect bone growth, destruction of the trigeminal provoked obvious disturbance of craniofacial growth while obturation of a nasal fossa produced no observable anomaly. Enucleation demonstrated the need for an intact globe for normal orbital growth, and resection of the mandibular condyle showed the primordial role of cartilaginous centers in mandibular growth. 相似文献
