Meniscal repair: Outcomes and clinical follow-up

A retrospective study of arthroscopic meniscal repair in 101 consecutive patients was conducted. Sixty-three patients constituted our study group. The arthroscopic technique used for meniscal repair was the inside-out method using malleable cannulas. Forty-five patients were available for clinical examination, with a mean follow-up of 27 months. Tegner and Lysholm scores were comparable to those previously reported for arthroscopic meniscal repair. The HSQ (similar to the SF-36) scores were equal to those from an age- and sex-matched normal population, indicating that individuals with repaired menisci do not have any residual negative effects on global health at mean 26.9 months' follow-up. The physical functioning subscale of the HSQ was found to be sensitive to patient perception of results. Complications included one case of restricted knee range of motion requiring arthroscopy and lysis of adhesions. Overall clinical results were 64% excellent, 27% good, and 9% failure. Age, sex, and length of the meniscal tear had no affect on clinical outcome.     

Nephrotic syndrome in a mother and her infant: relationship with cytomegalovirus infection

This case report describes infantile nephrotic syndrome (NS) in a baby girl with a clinically severe cytomegalovirus (CMV) infection. Culture of the baby's urine was positive for CMV and IgM anti-CMV antibodies were detected. After an unsuccessful course of corticosteroids, gancyclovir treatment was started and a remission of cutaneous, pulmonary, and renal symptoms was achieved. As the mother also developed NS at the end of pregnancy, a common etiology could be postulated, although there were no signs of recent CMV infection in the mother, only anti-CMV IgG. The relationship between CMV infection and glomerular disease is still unclear: NS may represent another manifestation of CMV disease.     

职业接触氯乙烯对生殖功能影响的调查

对全国１２个城市中１３个聚氯乙烯制造工厂中２７３６名接触氯乙烯的工人及３４４２名对照厂工人，进行了生殖功能的流行病学调查研究，结果表明，接触氯乙烯男、女工人的各项生殖结局指标与对照组比较无显著性差异，但女工氯乙烯接触组妊娠合并症的发生率明显高于对照组，表明氯乙烯对女工的妊娠过程有一定影响，因此积极改善劳动条件，不仅对保护工人健康，而且对保护其子代的正常发育成长也有重要意义。     

可溶性血管内皮生长因子受体-1与妊娠高血压疾病的关系

目的探讨可溶性血管内皮生长因子受体1(sFlt1)与正常妊娠和妊娠高血压疾病的关系。方法23例妊娠高血压孕妇(妊娠期高血压7例、轻度子痫前期3例、重度子痫前期9例、子痫4例)为妊娠高血压疾病组,20例足月妊娠血压正常孕妇作为对照组。应用半定量逆转录聚合酶链反应(RTPCR)技术检测两组孕妇分娩后胎盘组织中sFlt1的表达强度。结果妊娠高血压疾病组sFlt1mRNA1.45±1.47,与对照组1.04±0.69比较,差异无显著性(P>0.05)。子痫组(2.99±2.47)明显高于对照组(P<0.01)。结论sFlt1是维持正常妊娠所必需的因子。它表达水平的高低与妊娠高血压的发病有关,在子痫患者中表达明显增高。     

急性胰腺炎病因和诊治十年变迁(附725例报道)

急性胰腺炎的病因和早期诊治一直是临床医师关注的问题。目的：探讨近十年来急性胰腺炎病因、诊断和治疗的变迁及其对预后和住院费用的影响，总结急性胰腺炎的治疗经验。方法：采用回顾性临床研究方法，将725例人选患者分为两组．1993年4月～1998年12月就诊的患者为第一组，1999年1月～2002年8月就诊的患者为第二组：分析两组患者病因、诊断指标、治疗方案、并发症、预后、住院费用方面的变化。结果：比较两组病因，两组患胆囊炎胆结石者分别占72．3％和75．8％，高脂血症者分别占25．3％和25．8％，酗酒者分别占10．6％和9．7％。血清淀粉酶水平高于正常上限3倍的总检出率为66．9％．CT诊断总阳性率为92．0％。第一组46．9％的患者应用生长抑素，31．1％的重症患者发生胰腺假性囊肿，2．2％发生胰腺脓肿，死亡率为15．6％。第二组72-3％的患者应用生长抑素，13．2％的重症患者发生胰腺假性囊肿，2．2％发生胰腺脓肿，死亡率为6．5％。第二组的住院费用与第一组相比呈下降趋势，但无显著差异。结论：胆道疾病仍为急性胰腺炎的主要病因，血清淀粉酶和CT是急性胰腺炎较常用和可靠的检查手段。通过早期足量应用胰酶抑制剂(尤其是生长抑素)、肠道去污和改善胰腺微循环，可改善急性胰腺炎的预后，降低并发症发生率、死亡率和住院费用。     

妊娠期妇女外阴阴道念珠菌病的病原学和治疗研究

目的 调查孕妇外阴阴道念珠菌病(vulvovaginal candidiasis，VVC)的发病率，对检出的VVC进行病原学和治疗研究。方法 连续对产科门诊1000例孕妇进行VVC发病情况调查。对分离的念珠菌进行体外抗真菌药物敏感试验。对66例VVC患者应用咪康唑栓治疗，400mg／d，6d为一疗程。结果 孕妇VVC的发病率为12．7％(127／1000)。37．4％(374／1000)的孕妇以往有VVC病史，0．6％的孕妇为复发性VVc。127例VVC中，白念珠菌、光滑念珠菌、热带念珠菌和克柔念珠菌分别占87．1％、9．9％、1．5％和1．5％。有4例患者同时感染2种念珠菌。114株白念珠菌对咪康唑、克霉唑、氟康唑、伊曲康唑、制霉菌素耐药率依次为10．5％、2．6％、6．1％、7．9％和0。13株光滑念珠菌对咪康唑和制霉菌素均敏感，对克霉唑、伊曲康唑和氟康唑均敏感或剂量依赖敏感。应用咪康唑栓治疗的患者在治疗完成后1～2周及4～6周的病原学治愈率分别为84．8％和80．3％。结论 VVC是孕妇的常见病，白念珠菌仍然是主要致病菌，其次为光滑念珠菌。常用抗真菌药物对引起VVC的念珠菌存在不同程度的耐药率，应用咪康唑栓治疗孕妇VVC效果满意。     

Long-term follow-up and the role of surgery in adolescents with morbid obesity

PURPOSE: Obesity has become a health-care crisis in the United States. Adolescent obesity is now one of the most common childhood disorders, with 4.7 million American adolescents having a body mass index (BMI) greater than the 95th percentile. Most patients do not respond to diet modification or exercise programs and attention is now turning toward surgery as a source of weight loss in adolescents. Few studies have looked at the overall morbidity and mortality of weight loss surgery in this patient population. METHODS: This is a retrospective study of medical charts of 15 bariatric surgical procedures performed on 14 adolescents without known genetic syndromes associated with severe childhood obesity from 1971 to 2001 at the University of Minnesota. Procedures performed on these patients included vertical banded gastroplasty (n = 7), Roux-en-Y gastric bypass (n = 5), and jejunoileal bypass (n = 3). Jejunoileal bypass procedures were performed from 1971 to 1977, after which time this procedure was abandoned. Patient age ranged from 13 to 17 years (mean, 15.7 years). Mean follow-up time was 6 years, with 9 patients available for long-term follow-up. RESULTS: All procedures were performed using an open technique by 1 surgeon. There were no perioperative deaths; complications included 1 case of wound infection, 2 episodes of dumping syndrome that resolved without revision, 1 episode of hypoglycemia, and 1 case of short-term electrolyte imbalance in a patient who underwent jejunoileal bypass. The average BMI dropped from 58.5 +/- 13.7 to 32.1 +/- 9.7 kg/m(2) (P < .01)--a 45% reduction. CONCLUSIONS: Surgery for morbid obesity is safe and results in significant weight loss in adolescents who fail medical therapy.
