多种健康教育方法对武警某部新兵艾滋病知信行的影响

目的通过对武警某部 90 3名新兵艾滋病多种健康教育方法干预效果评价 ,为部队全面开展此项健康教育奠定基础和提供依据。方法整群多阶段抽样选定 4组对象 ,用 4种方法 (板书授课 VCD ;多媒体授课 VCD 资料 ;同伴教育 ;同伴教育 VCD 资料 )进行教育。结果干预前后 4种方法知识得分均有显著提高 (P <0 .0 1) ,除第 3种方法外 ,其余 3种干预前后态度和行为得分也有显著提高(P <0 .0 1)。 4种方法比较 ,以第 2种效果最佳 (P <0 .0 1)。结论在新兵群体采用同伴教育进行艾滋病健康教育效果不理想 ,应采取综合方法。     

用放免法测定脐血清中T_4T_3及TSH浓度筛选先天性新生儿甲低

本文用放免法测定脐血清T_4值(727例),T_3值(556例)及TSH值(700例)筛选先天性新生儿甲低。T_4值量男为9.56±4.29ug/dl,女为10.15±4.35ug/dl;T_3值量男为86.06±63.42ngldl,女为85.61±44.42ngld;TSH值男为13.77±12.69mIu/ml,女为13.94±12.51mIu/ml。三种激素男女之间均无显著差别,对24例可疑甲低复查了静脉血清T_4、T_3、TSH含量,T_4值均较脐血清高;T_3值较脐血清高出2—3倍TSH值均降到成年人水平。否定了甲低。并对早期诊断的取样问题进行了讨论。     

Lower lip paraesthesia following restoration of a second premolar tooth. Case report

A forty year old female patient developed paraesthesia of the right side of her lower lip following the placement of an extensive pin-retained amalgam restoration in her lower right second premolar tooth. Radiographs indicated that the mental foramen was close to the apex of this tooth and it was assumed that postoperative pulpitis and periapical inflammation had caused the paraesthesia through the effects of pressure on the mental nerve. The paraesthesia resolved following endodontic treatment of the lower second premolar tooth and the patient has had no further signs or symtoms.     

窥视下尿道内切开术治疗尿道狭窄或闭锁

采用窥视下尿道内切开术治疗尿道狭窄或闭锁５３例，其中４８例治疗成功。狭窄闭锁段≤３ｃｍ者，单纯冷刀切开即可；＞３ｃｍ者，冷刀切开后需加电刀切除疤痕组织，扩大尿道，尿道内皮管植入。３６例患者术后随访１～８年（平均４年６个月），２７例排尿通畅，尿流率和性功能正常。本文就操作要点和并发症防治等进行了详细讨论。     

Study of the role of vitamin B12 and folinic acid supplementation in preventing hematologic toxicity of zidovudine

Abstract: A prospective, randomized study was conducted to evaluate the role of vitamin B₁₂ and folinic acid supplementation in preventing zidovudine (ZDV)-induced bone marrow suppression. Seventy-five human immunodeficiency virus (HIV)-infected patients with CD4 + cell counts < 500/mm³ were randomized to receive either ZDV (500 mg daily) alone (group I, n = 38) or in combination with folinic acid (15 mg daily) and intramascular vitamin B₁₂ (1000 μg monthly) (group II, n = 37). Finally, 15 patients were excluded from the study (noncompliance 14, death 1); thus, 60 patients (31 in group I and 29 in group II) were eligible for analysis. No significant differences between groups were found at enrollment. During the study, vitamin B₁₂ and folate levels were significantly higher in group II patients; however, no differences in hemoglobin, hematocrit, mean corpuscular volume, and white-cell, neutrophil and platelet counts were observed between groups at 3, 6, 9 and 12 months. Severe hematologic toxicity (neutrophil count < 1000/mm³ and/or hemoglobin < 8 g/dl) occurred in 4 patients assigned to group I and 7 assigned to group II. There was no correlation between vitamin B₁₂ or folate levels and development of myelosuppression. Vitamin B₁₂ and folinic acid supplementation of ZDV therapy does not seem useful in preventing or reducing ZDV-induced myelotoxicity in the overall treated population, although a beneficial effect in certain subgroups of patients cannot be excluded.     

Renal disease in POEMS syndrome: report on a case and review of the literature

POEMS syndrome is a multisystem disorder associated with plasmacell dyscrasias. This report describes a patient with POEMS-associatedrenal disease and reviews the literature on biopsy-proven renalinvolvement in POEMS syndrome. Our patient had glomerulonephritiswith membranoproliferative features on light-microscopy withoutcharacteristic findings on immunofluorescence, and with ultra-structural evidence of glomerular microangiopathy. Ultrastructuralevidence of microangiopathy was also found in vasa nervorum.In 20 other cases of POEMS- associated renal disease, 16 hadglomerular disease. Light-microscopy showed membranoproliferative-likeglomerulopathy in 14 patients and glomerular microan giopathyin two. Ultrastructural evidence of microangi opathy was presentin all 15 patients in whom electron- microscopy was done. Thus,in most patients with POEMS-associated glomerular disease acharacteristic lesion is present with evidence of endothelialinjury. As endothelial damage is also found in endoneural vessels,generalized endothelial injury may play a role in non-renalmanifestations of POEMS syndrome. In previous reviews manifestationsof the POEMS syndrome were similar for patients with or withoutmyeloma. Among patients with biopsy-proven glomerular disease,however, myeloma patients are underrepres ented. Whether thisrepresents a sampling error or has true pathophysiological significanceremains to be established.
