Do children with autism have March birthdays?

One hundred people with autistic disorder (DSM-III-R) without a known cause who comprised a total population of children with autism were compared with "autistic-like" children, Asperger syndrome and age-matched comparison children from the general population and were examined with regard to month of birth. There was an excess of March birth in the group of children with autism. The possible reasons for this finding are discussed.     

COPD并发呼吸机相关肺炎的病原学分析

目的：分析慢性阻塞性肺病（COPD）有创机械通气并发呼吸机相肺炎（VAP）的病原以及药敏情况。方法：回顾分析年来本院肺科重症监护病房（RICU）内收治的28例VAP患者的临床资料、病原菌构成以及药敏结果。结果VAP的发生率为66．7％,共培养出细菌91株,真菌10株,其中革兰氏阴性杆菌（GNB）64株（70．3％）,革兰氏阴性球菌（GPC）27 株（29．7％）。COPD并发VAP居首位的细菌是嗜麦芽穿食单孢菌。结论COPD有效机械通气并发VAP以及GNB为主,VAP发生后细菌的耐药率普遍较高。在治疗VAP时应重视病原菌培养和药敏试验结果,合理应用抗生素。

Disseminated neuroblastomas under 1 year of age: cell biology and prognosis

Tumor specimens of 203 infants with neuroblastomas of different clinical stages — registered in successive multicenter clinical trials of the German Society of Pediatric Oncology — could be examined for N-myc amplification, chromosome 1-ploidy and — structure, CD₄₄ std. expression (in tumor tissue, and also in patients sera).Eightyseven (= 43%) of these infants had a non-localized, disseminated neuroblastoma, mainly involving sympathetic nerve tissue, lymphnodes, liver, skin, bone marrow and bones (46 patients were classified into the 4_s group, 41 patients in the true 4 group).If the clinical classification between stage 4 and stage 4_swas neglected, then 17 of these infants (= 20%) had N-myc amplification (4—64 copies) with 16 already dead. Seven of 9 examined patients with true stage 4 had chromosome 1p aberrations (with N-myc amplification in 5), and among the dead there were 2 with CD₄₄ negative expression.In another series, serum CD₄₄ std. was measured by ELISA, and the highest (significantly different) Kruskal-Wallis mean rank values (147.8) were found in infants (n = 6) with stage 4_s compared to the low mean-rank-value of 71.9 in patients with stage 4 (n = 65). Stage 1—3 patients (n = 42) had values of 99.8—88.6.Thus, infants with disseminated neuroblastomas, showing non-diploidy, normal chromosome 1p structure, non-N-myc amplification and high CD₄₄ std. expression in tumor tissue, and also high CD₄₄ std. values in serum, will have the highest chance of survival due to tumor-non-progression.On the other hand, N-myc amplification in the tumor cells was found to be characteristic for stage 4_s neuroblastoma patients with tumor progression (n=6). Therefore, 4_s neuroblastoma-patients with N-myc amplified tumors should be aggressively treated like true stage 4 tumor patients!     

肺炎性假瘤24例的临床X线误诊分析

目的探讨肺炎性假瘤的临床与X线误诊原因;方法依据临床与X线资料分析;结果均有不同程度的呼吸道症状,有14例痰中带血丝。肿块直径小于4cm11例,密度高而均匀,边缘光整,误诊为肺良性肿瘤。肿块直径大于4cm13例,密度不太均,边缘有分叶或有毛刺,误诊为肺癌;结论临床上多无急慢性感染症状,本病与其他占位性病变极相似,缺少特征,对本病缺乏认识是导致误诊的主要原因。肿块邻近胸膜,边缘出现尖角征,动态变化缓慢这3点对提高正确诊断率有独特的价值。     

新生儿通气相关性肺炎

目的：探讨新生儿通气相关性肺炎病因、病原菌、耐药情况、相关防治措施。方法：分析１０３ 例新生儿通气相关性肺炎患儿痰培养结果、诊治情况。结果：醋酸不动杆菌、铜绿假单胞菌、肺炎克雷伯杆菌是三种主要致病菌,耐药率高,对泰能、环丙沙星最为敏感。结论：革兰阴性杆菌是新生儿通气相关性肺炎重要病原菌,耐药率高,治疗较为困难,应积极预防。     

Detection of α S1-casein in vomit from bottle-fed babies by enzyme-linked immunosorbent assay

Summary This study describes a sensitive enzyme-linked immunosorbent assay (ELISA) using rabbit anti-bovine S1-casein antibody for the detection of commercial milk and milk-containing vomit. The antibody does not react with other human body fluids such as breast milk. The stability of S1-casein antigenic activity was examined after storage at different temperatures and enzyme digestion. There was no decrease after storage for one year at room temperature but 40% of the activity was lost after 6 months at 37°C. Enzyme digestion (6 hours, 37°C) resulted in 65 70% loss of activity but the antibody reacted with the peptide fragments of S1-casein. Vomit samples from 3 normal infants were tested by ELISA, and a S 1-casein could be detected in 1 cm² stain.
