锐劲特急性中毒的诊断与治疗

锐劲特(regent)是一种中等毒性杀虫剂,其杀虫机制能可是由于与中枢神经系统细胞膜上的γ-GABA受体结合后阻断氯离子通道,破坏了γ-GABA的神经系统抑制作用导致中枢兴奋症状,人过量接触该农药后也可出现抽搐等中枢兴奋症状,并可出现胃肠道症状;目前无特效的锐劲特急性中毒解毒药,只能对症治疗,苯二氮卓艹类和(或)苯巴比妥类药物可拮抗中枢兴奋症状。

Psoriasis in childhood and adolescence: evaluation of demographic and clinical features

BACKGROUND: The present study was aimed to define the gender ratio, familial occurrence, age of onset, precipitating factors, clinical types, nail and joint involvement of psoriasis in childhood and adolescence in Turkey. METHODS: A total of 61 children with psoriasis under 18 years old were evaluated retrospectively, for age, gender, age of disease onset, family history, concomitant disease, the clinical type of psoriasis, clinical localization, nail and joint involvement and treatment modalities. RESULTS: Of the patients, 23 (37.70%) were boys and 38 (62.30%) were girls. Mean age was 9.28 +/- 4.02 years in girls and 11.18 +/- 3.85 years in boys (9.96 +/- 4.03 years in all children). Mean age at the onset of the disease was 6.81 +/- 4.11 years in girls and 7.03 +/- 4.28 years in boys (6.89 +/- 4.14 years in all patients). In 14 (23%) cases, a positive family history was detected. The most frequent probable triggering factors were upper respiratory tract infections (14.8%) and positive throat culture for A group ss-hemolytic streptococcus (21.3%). Frequency of emotional stress and psychiatric morbidity were 54% and 9.8%, respectively. The most frequent localizations at onset were trunk (44.3%), extremities (54.0%), and scalp (36.0%). Three children (4.9%) had a history of dissemination from psoriatic diaper rash. In total, 51 (83.6%) patients presented with psoriasis vulgaris, eight (13.1%) with generalized pustular psoriasis, and the remaining two (3.3%) with erythrodermic psoriasis. CONCLUSION: The incidence of psoriasis among dermatological patients in childhood and adolescence was 3.8%. The disease tends to appear earlier in girls than boys. The authors suggested that stress and upper respiratory infections are the most important triggering factors in childhood and adolescence psoriasis.

肝移植术后巨细胞病毒性肺炎的临床特点和治疗方法

目的 探讨肝移植术后巨细胞病毒（CMV）性肺炎的临床特点和治疗方法。方法 回顾性分析2003年10月至2005年6月间施行肝移植的451例患者的临床资料，对肝移植术后CMV性肺炎的临床特点和治疗方法进行总结。结果 在451例患者中，发生CMV性肺炎7例，感染率为1．66％。CMV性肺炎的症状明显早于体征，7例患者均无明显诱因出现高热，约1周后逐渐出现干咳、气促、呼吸困难等；血氧饱和度降低，血气分析提示低氧血症；CMV pp65抗原检测均为阳性。CMV性肺炎患者采用更昔洛韦联合膦甲酸钠抗病毒治疗，同时采取停用免疫抑制剂、加用较大剂量的丙种球蛋白和适量的胸腺肽等的个体化免疫调节方案以及广谱抗生素等综合治疗方法，6例治愈，治愈率为85．7％。结论 CMV性肺炎的早期临床表现虽然缺乏特异性，但仍有规律可循，CMV pp65抗原检测法具有特异性和敏感性高的特点。采取联合抗病毒和个体化免疫调节等综合措施治疗CMV性肺炎效果确切。

臂丛神经卡压综合征的诊治

目的探讨位于臂丛神经及其前中斜角肌周围的神经卡压综合征的特点及其诊治方法。方法2003年7月～2006年1月,采用门诊收集病例,根据病情轻重分组,分别采用药物、局部封闭及手术方法治疗179例确诊为臂丛神经和(或)其属支卡压综合征的患者。其中采用药物、手法治疗89例；注射治疗74例,其中需要第二次注射32例；手术治疗16例,同时或分别进行双侧手术2例,需要第二次手术者1例。结果128例患者得到1个月～2年5个月随访。其中,药物手法治疗55例,症状均有不同程度改善或能维持现状。局部注射治疗58例(其中接受第二次注射者24例),2例出现心跳减缓,其余病例无并发症发生,VAS评分情况：1分2例,2分16例,3分20例,4分12例,5分3例,6分3例,7分2例；第二次注射结果：2分5例,3分16例,4分3例。手术治疗15例,其中10例术后症状得到明显改善,恢复工作。结论臂丛神经及其属支涉及其周围众多神经,可产生众多症状；明确病因后,治疗上以保守治疗为主,效果欠佳者采用手术治疗,均可取得较好疗效。

3DCRT技术治疗原发性肝癌的临床剂量学研究

目的探讨3DCRT技术治疗原发性肝癌的方法、处方剂量与疗效的关系。方法27例有随访结果的肝癌患者,对其肿瘤体积大小、位置、处方剂量及生存期作回顾性总结。结果治疗后肿瘤局部控制率为85.2%(23/27),1年生存率为70.4%(19/27),2年生存率为55.6%(15/27),3年生存率为33.3%(9/27)。所有病人无放射性肝炎等严重副反应发生。结论3DCRT技术治疗不宜手术的肝癌是一种无创而有效的治疗方法,可提高肝癌的局部控制率,不良反应轻微,病人生存质量得到提高。     

Do children with primary nocturnal enuresis have a retarded bone age? A cross‐sectional study

OBJECTIVE: Nocturnal enuresis is a common pediatric problem, the etiology of which is unclear. In recent years, various studies have been published stating that children with nocturnal enuresis exhibit growth and skeletal maturation retardation. METHODS: In this cross-sectional study, we included 27 patients (16 boys, 11 girls) between the ages of 6 and 14 years who had presented with primary nocturnal enuresis (PNE) complaints. We included in the evaluation 19 healthy subjects (12 boys, 7 girls), who were the siblings of the children with PNE, as the control group. RESULTS: The patients in both groups were similar in chronological age, bone age, height and weight, with no significant difference between groups (P>0.05). CONCLUSION: The two groups in our study consisted of the same genetic background. Thus, our results were found to be different from the previous studies. We have concluded that there is no direct relationship between enuresis nocturnal and skeletal maturation.
