Temporomandibular joint arthrocentesis: a simplified treatment for severe, limited mouth opening 总被引:12,自引:0,他引:12

Seventeen patients complaining of suddenly occurring, severe, and persistent limited mouth opening were treated by irrigation of the upper compartment of the affected temporomandibular joint with lactated Ringer's solution. This simple treatment was found to be highly effective in reestablishing normal opening and relieving pain for a follow-up period of 4 to 14 months. 相似文献

Wegener's granulomatosis (WG) is a multisystem inflammatory disease characterized by vasculitis, granuloma formation, and necrosis. Among 158 patients treated at the National Institutes of Health during the past 24 years, 145 (92%) had an otolaryngologic manifestation of their disease and 25 (16%) had subglottic stenosis (SGS). SGS varied from asymptomatic to life-threatening. Sixteen (80%) of 20 patients with fixed SGS required surgical intervention, including manual dilations, carbon-dioxide laser resections, and laryngotracheoplasty (LTP). LTP was performed with and without microvascular reconstruction. Thirteen of the patients required tracheostomy and all 13 were ultimately decannulated. Five patients who repeatedly failed dilations and/or endoscopic laser surgery underwent LTP. Since 1987, two patients have undergone LTP with microvascular free flaps. Both patients were subsequently decannulated. The authors' experience demonstrates that management of SGS in WG is complex, requiring individualized frequent multimodality interventions to achieve satisfactory results. Microvascular laryngotracheal reconstruction should be considered in the surgical armamentarium for patients with persistent stenoses. 相似文献

The nervous system may be involved during primary human immunodeficiency virus (HIV) infection. Recognized clinical syndromes include meningitis, meningo-encephalitis, myelopathy, polyneuropathy and rhabdomyolysis. We report three patients with unusual neurological presentations of primary HIV infection: intracranial hypertension, severe encephalopathy characterized by personality changes and regressive behavior, and iumbosacral radiculoneuropathy. In all, the neurological disorder had a benign course and resolved within a few months. Awareness of the large spectrum of neurological manifestations of primary HIV infection can enable early diagnosis and treatment. 相似文献

Cigarette smoking is known to adversely affect wound healing, and thus may jeopardize the success of dental implantation and implant-related oral surgery. The present study is aimed to present the influence of cigarette smoking on the success and survival of dental implantation as well as on the complication and success of implant-related surgery. We conclude that smokers undergoing both implant-related surgical procedures and dental implantation should be encouraged by their dentists, oral and maxillofacial surgeons, or treating physicians to cease smoking, emphasizing that smoking can increase complications and reduce the success rate of these procedures. 相似文献

OBJECTIVE: Preterm premature rupture of the membranes (PPROM) is believed to be caused, in part, by abnormalities of collagen and increased levels of oxidative stress. Elevated homocysteine levels have been shown to induce these same pathophysiologic changes. We tested the hypothesis that serum homocysteine levels would be higher in women with PPROM when compared with matched control women. STUDY DESIGN: A secondary analysis derived from 2 previously completed studies performed in the National Institutes of Child Health and Human Development Maternal-Fetal Medicine Units (MFMU) Network. We identified 99 study cases with PPROM (24 to 32 weeks' gestation) and matched them with 99 asymptomatic control women from an observational study of preterm birth prediction. Cases and control women were matched for race, gestational age at sampling, and MFMU Network center. Serum homocysteine levels were determined by immunoassay in batch fashion by personnel masked to study arm and clinical outcomes. Serum homocysteine levels were compared between groups, as were the baseline characteristics of maternal age, cigarette smoking, nulliparity, infections during pregnancy, and body mass index (BMI) <19.8 kg/m 2. Serum homocysteine levels were dichotomized as >75th, 90th, and 95th %ile of control women, and the likelihood of elevated homocysteine levels was determined in women who smoked, had a BMI <19.8 kg/m 2, or who had PPROM. Statistical analyses included the Wilcoxon rank sum, chi-square, and Pearson correlation coefficient, where appropriate. Baseline characteristics were controlled with a logistic regression model. RESULTS: Serum homocysteine levels measured in patients with PPROM were not significantly different from matched control women: median and (25th to 75th %ile): 4.9 (3.5-6.2) vs 4.8 (3.9-6.2 micromol/L), P =.73. In our population, neither the number of cigarettes smoked ( r = -0.08, P =.57), nor BMI ( r = -0.08, P =.24) correlated with serum homocysteine levels. The strongest association was seen in women with PPROM having serum homocysteine levels >95th %ile of control women (odds ratio [OR] 2.7, P =.10). After adjusting for baseline characteristics, no correlation between serum homocysteine level and the presence of PPROM was seen, OR 1.0 (.9-1.1); P =.99. CONCLUSION: Women presenting with PPROM did not have significantly increased serum homocysteine levels when compared with control women. 相似文献

Thyroid carcinoma usually presents as an asymptomatic thyroid nodule. Thyroid cancer may show microscopic vascular invasion; however, internal jugular vein tumor thrombus is a rare complication of thyroid cancer. A unique case of internal jugular vein tumor thrombus associated with thyroid carcinoma is presented and discussed. 相似文献

Background
Shear stress forces acting on liver sinusoidal endothelial cells following resection have been noted as a possible trigger in the early stages of hepatic regeneration. Thus, the morphology and gene expression of endothelial cells following partial hepatectomy or shear stress in vitro was studied. 相似文献929.

We have previously described two nucleolar proteins, named p14 and p21, in MMTV-induced T cell lymphomas. These proteins were identified by a monoclonal antibody (M-66) generated from a nontumorigenic, immunogenic variant of S49 T cell lymphoma. While p14 was common to several MMTV-derived T cell lymphomas, p21 was found only in highly tumorigenic variants of S49 cells. Here we report that p14 is the leader peptide of the MMTV env precursor. The epitope recognized by M-66 contains a putative nuclear localization signal. Actinomycin D was found to induce redistribution of p14/p21 from the nucleolus to the nucleoplasm. p14 coimmunoprecipitated and colocalized with the cellular protein, B23. Association with B23 has been previously reported for other auxiliary nucleolar retroviral proteins, such as Rev (HIV) and Rex (HTLV). 相似文献
