Posterior Laryngeal Clefts: Preliminary Report of a New Surgical Procedure Using Tibial Periosteum As an Interposition Graft

Objective: To present the preliminary results of a new surgical procedure for posterior laryngeal cleft repair. Design: Retrospective study in an academic tertiary care center. Method: The study included three male patients (age at surgery, 2, 13, and 14 mo). One presented with severe aspiration and cyanotic attacks, the two others with aspiration and recurrent chest infections. The types of laryngeal clefts included complete cleft of the cricoid with varying degrees of tracheal involvement but not further than the first six tracheal rings. Associated malformations included one VATER syndrome, one esophageal atresia, and one tracheoesophageal fistula. Surgery was performed under general anesthesia with nasotracheaI intubation. A vertical anterior laryngofissure was performed. The mucosal margins of the clefts were incised and then repaired in two layers with polyglactin sutures. The original feature of this procedure was the interposition of a small piece of tibial periosteum between the two layers. This fascia graft is known to be strong and resistant in cleft palate surgery. Main Outcome Measure: Clinical and endoscopic follow-up was used for evaluation of results. Results: The three patients had successful laryngeal repair at a mean follow-up of 6 months (range, 4-14 mo). Conclusion: The anterior laryngofissure provides a good surgical access to the cleft. The interposition of tibial periosteum allows durability of the cleft repair. A longer follow-up is needed to confirm these preliminary results. A computed tomography scan study and a study on the rabbit are planned in order to evaluate the outcome of these periosteal grafts.     

Improving the quality of child health services: participatory action by providers.

OBJECTIVE: To test a quality improvement approach called COPE (Client-Oriented, Provider-Efficient services), for use in strengthening health systems and supporting Integrated Management of Child Health (IMCI) efforts. DESIGN: Pre- and post-intervention observations of client/provider interactions, facility audits, staff and client surveys, and focus groups to evaluate differences between eight COPE intervention and eight matched non-intervention facilities after a 15-month intervention in 2001. SETTING: Primary care clinics in Guinea and Kenya. STUDY PARTICIPANTS: Health care providers and child caregivers. INTERVENTIONS: Over 15 months, the intervention supported four COPE exercises at each intervention site, supported supervisor training in quality management, and organized minimal training in topics selected by site staff as areas where training was needed. MAIN OUTCOME MEASURES: Differences in staff's and child caregiver's knowledge, attitudes, and practices; differences in the quality of services provided. RESULTS: On almost every quality indicator (over 65 indicators), whether reported by staff, observed by evaluators, or reported by clients, the intervention sites performed statistically significantly better than control sites. INTERVENTION: sites were cleaner and more pleasant, with more respect and information for clients, and more privacy. Staff had better personal communication skills, better diagnostic skills, and prescribing practices and gave better home care instructions to carers. Clients in intervention sites were more informed and more satisfied, and their children had better immunization coverage than those in control sites. CONCLUSION: COPE is a simple process, yet our study confirms that it can have a very dramatic effect on the quality of services. This study demonstrated how all areas of quality can be addressed by empowering health care providers to take action by using COPE. We suggest that COPE can complement Integrated Management of Childhood Illness (IMCI) training and can help to achieve better health for children.     

儿童白血病合并暴发型水痘带状疱疹病毒感染临床分析

目的探讨白血病患儿合并水痘带状疱疹病毒感染的临床特点及防治措施.方法回顾性分析1995年1月～2003年2月某院收治的6例合并水痘带状疱疹病毒感染的白血病患儿病历情况.结果 6例患儿均有发热及典型皮损,其中4例为持续高热(39～40.4℃)达1周,皮疹均为全身性分布.6例患儿均治愈,无水痘并发症发生.结论白血病患儿合并水痘带状疱疹病毒感染多呈暴发性感染,临床症状较重,容易出现并发症,应采取积极有效的防治措施.大剂量静脉用免疫球蛋白联合抗病毒药物等综合治疗效果较好.     

儿童胃电图与胃镜对照观察136例

目的比较分析胃电图和胃镜对于儿童胃病诊断的一致性,探讨胃电图在儿童胃病检查中的临床诊断价值。方法136例因消化道症状住院或就诊的人同时经胃镜及胃电图检查的患儿进行比较,按胃镜诊断结果,观察胃电图与胃镜诊断的符合率,对比分析胃电图的主频、振幅和节律变化,探讨变化规律。结果与胃镜诊断相比,胃电图对慢性浅表性胃炎的诊断符合率高达95.8%,对器质性胃部疾病的诊断符合率不到40%。结论虽然胃镜仍为一种不可替代的检查手段,但胃电图对于儿童胃部功能性疾病的诊断却有着重要意义,可作为初筛的一种重要手段。     

儿童嗜酸性淋巴肉芽肿的临床特点与治疗

目的 探讨儿童嗜酸性淋巴肉芽肿（ELG）的临床特点和诊治方法，以提高对本病的认识。方法 回顾性分析5例ELG患儿的临床特征、实验室检查、病理、治疗及疗效，并进行相关文献复习。结果 ELG5例均为男童，主要表现为多发性皮肤软组织肿块和淋巴结大，其中1例并肾病综合征，2例有反复湿疹样皮疹，1例2次发生喘息性支气管炎，患儿均无肝脾大，生长发育良好。最初单纯化疗4例均复发，经配合局部放疗或加用环孢素（CsA）等治疗后未复发。结论 儿童ELG临床及病理特点与成人相似，但儿童发病较少。单纯化疗易复发，配合放疗、手术、应用CsA等综合治疗可提高疗效。
