Enlarging skull fractures in children

Large skull fractures are conventionally followed radiographically until healing occurs. Fractures which enlarge or remain unhealed are commonly termed leptomeningeal cysts or growing skull fractures. This study of ten children with this injury and a review of the literature shows that a true leptomeningeal cyst is seldom present and that skull fractures do not grow. Moreover, careful history-taking and physical examination will correctly identify all enlarging or unhealed skull fractures of childhood without the need for plain radiographs or computed tomography of the skull.     

先天性胆管囊肿（附28例报告）

目的：探讨先天性胆管囊肿的病因、分型、诊断和治疗方法。方法：回顾１９８６至１９９６年１０年间收治的先天性胆管囊肿２８例进行分析。结果：２８例中Ⅰ型１９例（６７８５％）,ＩＶＡ型８例（２８６％）,ＩＶＢ型１例（３６％）。Ｂ超检查２６例,２４例手术证实;ＣＴ９例７例手术证实。手术治疗为最佳手段,以囊肿切除为首选。本组２５例手术治疗,囊肿切除１３例（占５２％）。结论：Ｂ超为主要诊断手段。先天性胆管囊肿癌变率随病程延长而逐渐上升,故切除囊肿为首选治疗手段     

Retrospective analysis of 31 cases of nasopalatine duct cyst

OBJECTIVE: To perform a retrospective analysis of patients with nasopalatine duct cysts (NPDC) in Brazil and compare with previous analyses. MATERIALS AND METHODS: The files of the Laboratory of Oral Pathology (Minas Gerais Federal University) from 1966 to 1997 were reviewed. Demographic, clinical and histologic data of patients with nasopalatine duct cysts were collected. RESULTS: The mean age of patients with nasopalatine duct cysts at the time of diagnosis was 37.4 years and with a predilection for males. The majority of cases were asymptomatic. Histologically, non-keratinized stratified squamous epithelium alone or in combination with other epithelia was observed in 93% of the cases. Recurrence was not recorded. CONCLUSION: The demographic, histopathological, radiographic, and clinical data of the NPDC in our series are similar to previous studies in other populations.     

上皮植入性虹膜囊肿的激光治疗

目的：观察Ｎｄ：ＹＡＧ激光治疗上皮植入性虹膜囊肿的疗效。方法：治疗前详细了解囊肿与周围组织的关系,首先激穿囊肿前壁,使腔内液体引流,然后降低能量,照射囊肿后壁及周围组织,以尽可能破坏上皮细胞,减少复发。激光治疗单脉冲能量为０．４ＭＪ,每次治疗总量为２０～３５ＭＪ。结果：所有治疗眼的视力均有不同程度提高。经术后６个月～１年的随访观察,未见明显复发。结论：激光治疗上皮植入性虹膜囊肿,既可破坏囊壁的上皮细胞,又可避免和减少囊肿邻近组织的损伤及反应,以尽可能多地保留和恢复有效视功能,以避免患者因再次手术所带来的痛苦,疗效满意     

微波治疗口腔粘液腺囊肿67例临床观察

总结微波治疗口腔粘液腺囊肿的经验,探讨治疗口腔粘液腺囊肿的方法。方法：使用微波多 功能治疗机,通过微波辐射探头直接作用于囊肿,使囊肿组织坏死、脱落。结果：６７例中治愈６３例（９４．０３％）,有 效４例（５．９７％）。无一例复发。结论：微波治疗口腔粘液囊肿,操作简单,疗效可靠,无不良反应,是治疗口腔粘 液囊肿的有效方法。     

组合硬化剂治疗肾囊肿远期疗效观察

目的：研究组合硬化剂对家兔胆囊的硬化作用,观察治疗肾囊肿的远期临床疗效。方法：应用四环素与氟美松组合硬化剂注入家兔胆囊,与生理盐水和无水乙醇对比观察其对胆囊壁的作用;与无水乙醇对比观察介入硬化治疗肾囊肿的疗效。组合硬化剂治疗组４１例,男２３例,女１８例,年龄４３岁－７２岁;无水乙醇对对照组４０例,男２８例,女１２例,年龄４５岁－７０岁。

A case of small cerebral cyst and pericentric inversion of chromosome 9 that developed schizophrenia-like psychosis

A case of schizophrenia-like psychosis (psychotic disorder not otherwise specified according to the DSM-IV criteria) with pericentric inversion on chromosome 9 [inv.(9) (p11; q13)] is reported. In this case, a minor brain anomaly, a small cyst in the left subcortex, was observed on magnetic resonance imaging of the brain. In the clinical course, prominent chronic hallucinations were observed; however, there was no evidence of the disorganization of personality, delusion, and deterioration in level of functioning that are usually seen in schizophrenia. This case and a review of the literature indicate that the pericentric region of chromosome 9 might be a potential areas of interest for the aetiology of psychiatric disorders. The phenotype-karyotype relationship of pericentric inversion on chromosome 9 and its relationship to psychosis are discussed.     

危重型胆总管囊肿的诊治体会
