Erosive pustular dermatosis of the scalp in an adolescent with near‐total hair regrowth: Case report and review of the literature

Erosive pustular dermatosis of the scalp (EPDS) is an uncommon chronic inflammatory response to scalp trauma that usually resolves with cicatricial alopecia. It most commonly affects elderly patients with a history of actinic damage. Herein, we describe a 16‐year‐old girl with acrofacial dysostosis type 1 presenting after surgery with crusting purulent scalp lesions, whose clinical presentation and histopathologic findings were consistent with EPDS. A review of the literature on EPDS in children is also detailed.

目的：寻找深度大面积\烧伤的早期治疗方法。方法:大面积深度烧伤于4－5天即行切痂，以异体甘油皮为支架，将有限的自体皮制作成微粒皮后均匀地复合植于创面。结果：对5例共12个肢体2个躯干进行早期切痂后异体甘油皮＋自体微粒皮的复合移植，成活后的创面平堤，外观平整，颜色淡红或近拟正常皮肤，触饮，收缩少，结论：异体甘油保存皮＋自体微粒皮复合移植是大面积深度烧伤较理想的治疗方法。     

谷氨酰胺肠外营养对创伤后多器官衰竭患者的营养作用

目的探讨补充谷氨酰胺(Gln)的肠外营养在严重创伤后多器官衰竭(MOF)患者治疗中的作用。方法采用随机对照方法,将60例MOF患者分为Gln组和对照组,每组30例。Gln组给予Gln1.5ml/kg联合常规治疗[热量104～125kJ/(kg·d),其中脂肪供热40%,氮供给量为0.2～0.25g/(kg·d)的完全胃肠外营养(TPN)支持];对照组仅给予常规治疗,连续7d。对照分析营养指标、免疫指标、并发症及临床结果。结果所有患者营养指标(血清白蛋白、前清蛋白、转铁蛋白)和免疫指标(IgG、IgA、IgM)明显减低,处于负氮平衡。第8天时,Gln组营养指标明显高于治疗前及对照组(P<0.05),负氮平衡得到纠正(P<0.05),而对照组仅血清白蛋白、转铁蛋白较治疗前增高(P<0.05),仍处于负氮平衡(P>0.05)。Gln组免疫指标明显高于治疗前及对照组(P<0.01),而对照组仅IgG高于治疗前(P<0.01)。对照组14例(46.7%)出现了血清胆红素、丙氨酸转氨酶和血糖的升高,而Gln组仅4例(13.3%)增高(P<0.05),至14d时对照组病死率为36.7%,而Gln组仅为10%,两者相比差异有显著性(P<0.05)。结论应用Gln的肠外营养能够明显纠正MOF患者的营养代谢障碍,纠正负氮平衡,增强免疫功能,降低并发症及病死率。     

Expression of epithelial matrix molecules collagen and laminin and corresponding integrins in chronic wounds

Re-epithelialization of cutaneous wounds is a coordinated process of proliferation and migration of keratinocytes at the wound edge. The study objective was to identify the differences in epidermal morphology, keratinocyte proliferation and matrix molecules (laminin 1, laminin 5, type IV collagen) and their specific integrin (α3, α6) expression in biopsies of meshed split thickness grafted and chronic wounds. The mean mitotic index of keratinocytes (ratio of cell cycle associated antigen Ki-67 expressing keratinocytes to basal keratinocytes) was highest in chronic wounds (38.7%) compared to acute wounds (22.25%, range 5.7% to 54%). The mean thickness of the hyper-proliferative epithelium at the wound edge of chronic wounds was 0.69 mm compared to 0.15 mm at the wound margin of split thickness grafted wounds. Both chronic wounds and skin grafted wounds exhibited strong laminin 5 immunoreactivity at the basal side of the epithelium, which extended under the most forward keratinocytes. Laminin 1 and type IV collagen immunoreactivity did not extend to the wound margin in either skin grafted or chronic wounds. In both transplanted skin and chronic wounds, the integrin sub-units α3 and α6 exhibited a strong pericellular immunoreactivity on the leading keratinocytes of the wound margin. Our data demonstrates that the proliferation of keratinocytes and the expression of associated integrins are not impaired in chronic wounds.

穿透性角膜移植联合瞳孔成形术的临床观察

目的观察穿透性角膜移植联合瞳孔成形术的效果。方法４８只眼行穿透性角膜移植术的同时对虹膜缺损进行修复，成形瞳孔。术后随访６～８９个月。结果植片透明者３８只眼（７９．２％），视力恢复０．１以上者３１只眼（６４．６％），瞳孔修复接近正常者４３只眼（８９．６％）。结论穿透性角膜移植联合瞳孔成形术，可减少术后并发症、改善植片的预后及视功能。对波及瞳孔的虹膜缺损，联合行瞳孔成形术效果较好。     

Open extremity fracture penetrating the skull

Preventing accidental injury to young children in the home using volunteers

Accidental injury in the home is a major cause of death andill-health among young children. Reducing home safety hazardsby the use of safety devices such as stair barriers and safetytaps has the potential to prevent home injuries. Little is knownabout levels of home safety hazards or how to encourage parentsto reduce hazards. The Safe Place Project examined parents'knowledge of home safety and the prevalence of safety hazardsin homes where there were young children. The study also evaluatedthe effectiveness of a low-cost strategy aimed at reducing homesafety hazards. The strategy used trained volunteers to providehome safety checks and tailored safety education in conjunctionwith increasing the availability of home safety devices. Onehundred and six families with young children participated inthe project. Some homes contained many hazards, with 43% ofthe sample having more than 10 home safety hazards. At follow-up,the intervention group showed a significant reduction in homehazards and a trend towards an increase in knowledge of homesafety.     

外伤性肝破裂的救治

目的 分析创伤性肝破裂外科多种干预治疗的效果。方法 总结分析1982-2002年我院收治创伤性肝破裂76例的救治方法和病死率。其中Ⅲ级以上的严重肝破裂46例(60．53％)。手术治疗56例，手术方式包括单纯修补、清创性肝切除、规则性肝切除、肝周填塞止血；非手术治疗20例。结果 手术组：治愈44例，术后并发症17例均经保守治疗治愈，死亡12例，其中术中死亡2例；非手术组：治愈12例，好转6例，2例失访。全组治愈64例，死亡12例，病死率15．8％。结论 Ⅰ-Ⅱ级单纯性外伤性肝破裂可保守治疗；手术是治疗创伤性肝破裂的主要措施，正确的手术方式，积极处理合并伤，重视综合治疗可提高救治成功率。     

海水浸泡弹烧复合伤血细菌学与内脏病理学的变化

目的 探讨海水浸泡弹烧复合伤伤后血液细菌学变化与内脏病理学变化之间的关系。方法 建立海水浸泡弹烧复合伤模型后，依模型将15只成年杂种犬随机分为单纯弹烧复合伤组(简称非浸泡组，7只)和海水浸泡弹烧复合伤组(简称浸泡组，8只)，于伤后即刻和4、7、10、20、28h共6个时相点抽取静脉血进行血细菌培养。另于伤后28h和濒死期将动物活杀，取心、肝、肺、肾行病理学观察。结果 浸泡组动物菌血症出现较早且严重。导致菌血症的细菌来源复杂，不仅有肠道菌群，还有海水特有菌群和皮肤常驻菌群。在内脏器官组织病理学上，不仅有不同程度的血液循环障碍及退行性变，还有严重的炎症反应。结论 在海水浸泡弹烧复合伤中，伤后出现的严重菌血症进一步加重了内脏器官损伤。
