Nasal fractures in children

Summary A group of thirty children with nasal fractures was evaluated retrospectively by means of a questionnaire and hospital records. Age at the time of injury ranged from age 3 to 12 (mean = 8.6) years and mean follow-up period was 9 years. Eight patients reported some degree of nasal obstruction post reduction, but only one patient required submucous resection and two patients underwent septorhinoplasty for appearance. No patients reported class III malocclusion, or required orthodontic treatment or maxillofacial corrective surgery for maxillary hypoplasia. We concluded that a childhood nasal fracture treated by closed reduction does not have deleterious effects on facial or nasal growth.This work was supported in part by the Brigham Surgical Group Foundation, Inc., Boston, Massachusetts, USA

术后胆漏和继发胆管狭窄的内镜治疗

胆漏和继发胆管狭窄是严重的外科并发症，传统的治疗方法是再次开腹手术，但再手术并发症多，死亡率高。而内镜胆管造影不仅可明确诊断，且内镜下治疗具有安全、疗效肯定、创伤小和并发症少等优点，可作为大多数胆漏和胆管狭窄患者首选治疗方法。

牵张力对体外培养兔鼻软骨细胞影响的实验研究

目的：探讨牵张力对体外培养的不同年龄兔鼻软骨细胞增殖活性的影响及牵张力大小与兔鼻软骨细胞增殖活性改变的量效关系。方法：将第4代体外培养的新生及6周龄新西兰白兔兔鼻软骨细胞置于细胞膜式牵张力施加装置上培养，流式细胞仪检测不同的牵张力(5kPa、10kPa)在0-12h内对兔鼻软骨细胞增殖活性的影响。结果：0-10h内5kPa牵张力组软骨细胞增殖指数随着牵张力作用时间的延长不断上升，增殖指数峰值位于10h处；0～8h内10kPa牵张力组软骨细胞增殖指数随着牵张力作用时间的延长不断上升，增殖指数峰值位于8h处；5kPa较10kPa牵张力对体外培养兔鼻软骨细胞具有更大的促增殖作用；牵张力对体外培养的新生兔兔鼻软骨细胞具有更大的促增殖作用。结论：牵张力可促进体外培养的新生及六周龄新西兰白兔兔鼻软骨细胞增殖活性。提示我们鼻软骨牵张方法不仅适用于临床矫治新生儿唇腭裂伴发鼻畸形，而且有可能用于矫治1岁左右婴儿甚至更大年龄患儿的唇腭裂伴发鼻畸形。     

不同临床和病理分型对肝门部胆管癌切除术预后的影响

目的 研究临床和病理分型与肝门部胆管癌切除术疗效的关系。方法总结1993年至2004年在解放军总医院肝胆外科手术切除的肝门部胆管癌198例病例资料。结果临床分型Ⅰ型34例，Ⅱ型60例，Ⅲa型27例，Ⅲb型33例，Ⅳ型19例，Ⅴa型6例。Ⅴb型19例。病理高分化腺癌35例，中分化腺癌52例，低分化腺癌54例，三者的中位生存期分别为29．5、11、5．5个月；病理切缘阴性者与切缘阳性者生存率有显著性差异（P 〈0．05）。手术并发症出现率41．4％，围手术期死亡1例。结论肝门部胆管癌根据临床分型进行相应的手术治疗；病理切缘阴性是影响预后的主要因素之一；围手术期正确处理，是减少手术并发症，提高患者生活质量和延长生存期的关键。     

Open rhinoplasty for treatment of nasal tip haemangioma

Haemangiomas are the most common tumours of infancy. They typically proliferate then involute with considerable variation as regards to their rates of proliferation and involution. Haemangioma of the nasal tip is a lesion of special characteristics. During proliferation, it expands, contracts and deviates the nasal cartilages. Particularly, it regresses slowly and frequently involutes incompletely. That is why excision of the lesion is frequently suggested. The present study was conducted to evaluate open rhinoplasty after initial non-excision treatment modalities namely, intra-lesional corticosteroid injections and laser treatment, as a protocol of treatment for nasal tip haemangiomas. Twelve patients with nasal tip haemangiomas were included in the present study. Patients of both sexes, of different ages, with deep and mixed haemangiomas were studied. Disfigurement was the constant presenting symptom. Initial non-excision treatment reported different responses as denoted by the regression of the lesions’ size. Haemangiomas constantly extended between the medial crura of the alar cartilages as noted by the constant widening of the columella pre-operatively and the obvious separation of the nasal cartilages intra-operatively. This separation was constantly found to require approximation by sutures. The results of the present study concluded that whenever an early presentation with nasal tip haemangioma could be established, initial non-excision treatment followed by open rhinoplasty could be a useful protocol of treatment. Within the limitations of the present study, this protocol could achieve an early, safe and effective treatment for nasal tip haemangiomas with provisionally acceptable cosmetic outcomes so far.

Spontaneous gallbladder perforation—An unusual presentation of carcinoma of the pancreas

A 50 year old man with a two month history of upper abdominal pain and a one month history of anorexia and weight loss, presented with icterus and evidence of peritonitis. Laparotomy revealed biliary peritonitis which had been caused by a rupture of the fundus of the gallbladder. The common bile duct was dilated and there was a large growth in the head of the pancreas with multiple hepatic metastases. A cholecysto-jejunostomy and gastrojejunostomy were done and the patient had an uneventful recovery.     

New monoclonal antibodies reacting with bile ducts: further insights into the pathogenesis of bile ductular proliferation in biliary diseases.

We have produced a range of monoclonal antibodies which stain human intrahepatic bile ducts of different sizes. Amongst 26 monoclonal antibodies produced, five clones reacted specifically with bile ducts of different sizes, of which three have been maintained in culture and their viability following freezing and thawing confirmed. Staining patterns varied between normal adult liver tissue, normal fetal liver tissue and a variety of hepatobiliary diseases. The antibodies provide further evidence of the immunological heterogeneity of the human intrahepatic biliary tree and support the hypothesis that proliferating bile ductules are derived from periseptal hepatocytes. The preparation of the antibodies, their staining reactions in normal adult, normal fetal and a variety of liver diseases are described.
