Mycoplasma pneumoniae-associated nephritis in children

 Mycoplasma pneumoniae infection is a rare cause of acute nephritis. Six children (2 girls) aged 5–10 years, admitted for nephritis, had serological tests showing recent Mycoplasma pneumoniae infection. The diagnosis of Mycoplasma pneumoniae infection was based on the presence of serum IgM, detected either by immunofluorescence (IF) (n=1) or enzyme-linked immunosorbent assay (n=5). Four children had a renal biospy, with analysis of parenchymal Mycoplasma pneumoniae components by indirect IF and polymerase chain reaction. Extrarenal symptoms were: respiratory (n=3), ear, nose, and throat (n=2), gastrointestinal (n=3), hepatic (n=1), neurological (n=1), articular (n=1), and hematological (n=3). The patients presented with acute nephritis (1 had a nephrotic syndrome) or with acute renal failure and proteinuria. Pathological findings included type 1 membranoproliferative glomerulonephritis (MPGN, n=1), proliferative endocapillary glomerulonephritis (n=2), and minimal change disease (n=1). The patient with type 1 MPGN progressed rapidly towards end-stage renal failure because of a congenital solitary kidney. Among the patients with endocapillary glomerulonephritis, 1 relapsed 6 months later and remained proteinuric, while the other recovered, as did the child with minimal change disease. The search for Mycoplasma pneumoniae antigens and nucleic acids in renal tissue was negative. However, the absence of the microorganism in the kidney is a common feature of post-streptococcal glomerulonephritis. We conclude that Mycoplasma pneumoniae is a rare yet potential cause of acute glomerulonephritis. Received: 13 September 1996 / Revised: 16 June 1998 / Accepted: 18 June 1998     

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.
