PURPOSE: The aim of this study was to identify contributing factors to skeletal relapse by analyzing cephalometric changes after bilateral sagittal split ramus osteotomy. PATIENTS AND METHODS: This study included 60 consecutive patients who underwent either mandibular advancement (30 patients) or setback surgery (30 patients). There were 36 women and 24 men (mean age, 23 years). The radiographs of these patients taken immediately before operation, at 1 week, and 14 months postoperatively were studied. To analyze the influence of hyper- and hypodivergent facial patterns on the surgical outcome, the patients were divided into 3 groups according to the mandibulo-nasal plane angle. The position of the maxilla was also taken into account. RESULTS: Measured at B-point, skeletal relapse was 1.3 mm (30%) after mean advancement of 4.4 mm and 0.8 mm (12%) after setback of 6.0 mm. The magnitude of the surgical movement correlated with skeletal relapse. However, the correlation was not linear. Advancement of greater than 7 mm is associated with an increased tendency to relapse (r=0.52), but setback of more than 12 mm with a decreased tendency (r=-0.95). The retrognathic patients with a high mandibulo-nasal plane angle (hyperdivergence) had 30% higher relapse rate. Patients with hypodivergent facial patterns had less relapse in both advancement and setback surgery. CONCLUSION: Skeletal relapse was affected by magnitude of surgical movement and different facial patterns according to the mandibulo-nasal plane angle; however, influences of both factors were different between mandibular advancement and setback. 相似文献

Do we bring back the observation of a patient aged of 42 years having a mitro-aortic valvulopathy who present since 3 months a level III dyspnea, a fever to 39 degrees C, a change of the general state and a splenomegaly. To the chest x-ray we note a pulmonary parenchymatous focus. Echocardiography puts in evidence a mitral illness to stenosis predominance and an aortic illness complicated of a graft bacterial with an abscess of the mitro-aortic trigone. Haemocultures were negative and the serology of the Rickettsia was positive. The diagnosis of infective endocarditis to Coxiella Burnetii is kept and is the patient put under Doxycycline 200 mg/j, Hydroxychloroquine 2 cp/j and Ofloxacine 400 mg/j. Will the two first antibiotics be pursued to the 18th month. The patient benefited, after 20 days of three antibiotics therapy, of a duplicate aortic and mitral replacement with simple following. 相似文献

True intramedullary spinal cord lipomas are extremely rare. Two cases of intramedullary spinal cord lipoma are presented. The patients did not exhibit any form of spinal dysraphism. The patients presented with gait difficulty, upper limb weakness, sphincter disturbance, dysesthesias and neck pain. The tumors were removed sub-totally and the neurological grade improved postoperatively in one of the patients. 相似文献

Background
Knowledge about coronary heart disease (CHD) and its risk factors is an important pre-requisite for an individual to implement behavioral changes leading towards CHD prevention. There is scant data on the status of knowledge about CHD in the general population of Pakistan. The objective of this study was to assess knowledge of CHD in a broad Pakistani population and identify the factors associated with knowledge. 相似文献126.
We encounter pathogens on a daily basis and our immune system has evolved to mount an immune response following an infection. An interesting phenomenon that has evolved in response to clearing bacterial and viral infections is called immunodominance. Immunodominance refers to the phenomenon that, despite co-expression of multiple major histocompatibility complex class I alleles by host cells and the potential generation of hundreds of distinct antigenic peptides for recognition following an infection, a large portion of the anti-viral cytotoxic T lymphocyte population targets only some peptide/MHC class I complexes. Here we review the main factors contributing to immunodominance in relation to influenza A and HIV infection. Of special interest are the factors contributing to immunodominance in humans and rodents following influenza A infection. By critically reviewing these findings, we hope to improve understanding of the challenges facing the discovery of new factors enabling better anti-viral vaccine strategies in the future. 相似文献

Objective
To isolate the entomopathogenic fungus Metarhizium anisopliae (M. anisopliae) in the local environment, and evaluate its efficacy against the suspected dengue vector Aedes albopictus in Pakistan.Methods
According to the standard procedure, M. anisopliae was isolated from the dead mosquitoes which were collected from the field or dead after the collection. Bioassay was performed to determine its efficacy.Results
The results indicated that M. anisopliae had larvicidal effect with LC50 value 1.09×105 and LC90 value 1.90×1013 while it took 45.41 h to kill 50% of tested population.Conclusions
Taking long time to kill 50% population when compare with the synthetic insecticides, is the only drawback for the use of entomopathogenic fungus but these bio-pesticides are safe for the use. 相似文献128.
