Risk Factors for a First Febrile Seizure: A Matched Case-Control Study

Summary We conducted a matched casecontrol study to identify risk factors for first febrile seizures, with special emphasis on characteristics of the acute illness episode. Cases were identified through hospital emergency departments; controls were identified through outpatient clinics and emergency departments. Sixtynine children with first febrile seizures and no history of previous unprovoked seizures were matched for age (±6 months), site of routine pediatric care, and date of visit (±weeks) with 1 or 2 febrile controls who had no history of previous febrile or unprovoked seizures. Medical records for the index visit were reviewed, and parents were interviewed by telephone. Illness characteristics examined included height of temperature, type of underlying illness, contact with a physician during the illness but before the index visit, and use of acetaminophen or decongestants. Family history of febrile and of unprovoked seizures, sociodemographic characteristics, daycare use, and selected preand perinatal variables were also studied. On multivariable analysis, significant independent risk factors were height of temperature, history of febrile seizures in a firstor in a higher degree relative. Gastroenteritis as the underlying illness had a significant inverse (i.e., protective) association with febrile seizures. Maternal smoking during pregnancy was a marginally significant predictor of febrile seizures.     

妊娠合并急性阑尾炎的临床特点

报告妊娠期急性阑尾炎３１例，占急性阑尾炎的０６３％，占女性急性阑尾炎的１５６％。手术治疗５８％。阑尾穿孔２２６％，其中完全流产、先兆流产、低位肠瘘各３２％。本病特点为：早期：症状、体征与一般病人相似，但恶心、呕吐易被误认为是妊娠反应；中期：疼痛和压痛部位向上向内移位；晚期：腹痛和压痛位于右上腹或右侧腹部，易被误认为子宫收缩痛。本病炎症容易播散，可发生早产、流产或孕妇死亡。应早期确诊，及时手术。     

腹腔镜卵巢穿刺内凝治疗多囊卵巢不孕症的临床研究

目的探讨腹腔镜卵巢穿刺内凝对多囊卵巢不孕症的治疗价值。方法１５１例腹腔镜卵巢穿刺内凝术（实验组）和１５１例开腹卵巢楔切术（对照组）治疗多囊卵巢不孕症配对对比研究。结果实验组的手术时间３３．１±７．２ｍｉｎ，术中失血１５．６±４．７ｍｌ，总排卵率９２．０５％，总妊娠率４９．６７％，均优于对照组（Ｐ＜０．０１）；术后雄激素、ＬＨ／ＦＳＨ下降幅度小于对照组（Ｐ＜０．０１）。随时间推移，两组术后排卵巢、妊娠率均有下降倾向，而术后雄激素、ＬＨ／ＦＳＨ则有逐渐回升的倾向。结论腹腔镜卵巢穿刺内凝术对多囊卵巢不孕症有较好的治疗效果     

异常孕产史妇女风疹病毒感染的研究

目的了解孕妇风疹病毒的感染率；为早期预测异常妊娠的出现、及时防治提供理论依据。方法采用酶联免疫吸附法（ＥＬＩＳＡ）检测２０６例有异常孕产史妇女和８１０例正常孕妇血清中特异性抗风疹ＩｇＭ抗体。结果有异常孕产史的妇女风疹病毒感染率明显高于对照组（ｘ２＝１１．３３Ｐ＜０．０１）。结论风疹病毒感染是造成异常妊娠的主要原因之一；孕前或孕早期进行风疹病毒感染的检测，对降低异常妊娠的出现具有重要意义。

妊娠期妇女的人体测量及脂肪贮存

本文对30名居住北京城近郊区的健康初产孕妇,于妊娠早期、中期及末期连续进行人体测量,包括身长,体重,皮下脂肪厚度和肢体围,以观察孕期体重增长,身体脂肪含量及肌肉情况。测量结果,受试者从妊娠6周至37周平均体重增长13.0kg。三头肌、二头肌部位皮脂厚度在孕期无明显变化。肩胛下皮脂厚度至孕末期时明显较早期增加。髂骨上皮脂厚度在孕中期及末期均有明显增长,与早期相比差別显著。据皮脂厚度计算身体密度及脂肪含量络果,至孕末期身体脂肪含量占体重的百分比共增加3.7％。肢体围测量结果,仅臀围在妊娠中期后至末期明显较早期增大。大腿上部围略有增加,但与早期差别无显著意义。大腿中部、小腿腓肠肌部及上臂围孕期均无明显变化。

Tubal patency and fertility outcome after expectant management of ectopic pregnancy

Objective: To study tubal patency and fertility outcome of patients with expectantly managed ectopic pregnancy (EP).

Design: A prospective study.

Setting: Department of Obstetrics and Gynecology, Turku University Central Hospital, Turku, Finland.

Patient(s): Thirty patients who wanted to become pregnant again were treated successfully by expectant management of EP.

Intervention(s): Patients were examined with posttreatment hysterosalpingography, and they filled out a questionnaire about their subsequent pregnancies.

Main Outcome Measure(s): Free passage through open lumen showing tubal patency; number of full-term pregnancies and EPs revealing relative rate of subsequent fertility.

Result(s): A free passage through the diseased tube was seen in 93% of the cases (28 of 30). Two of the 24 patients (8.4%) who wanted to become pregnant had an obstruction in the diseased tube. One (4.2%) of them had a normal opposite tube and later had a normal pregnancy. The other (4.2%) had an obstruction in both tubes and subsequently had a repeat EP. One of the 6 patients had an EP (this patient did not want to become pregnant and did not use contraception). However, her posttreatment hysterosalpingography was normal. In total, the subsequent pregnancy rate was 88% (21 of 24), and the rate of repeat EP was 4.2% (1 of 24).

Conclusion(s): Patients who are treated with expectant management have a good long-term fertility outcome. Spontaneous regression of EP does not lead to increased harm or damage to the tube, i.e., the risk for repeat EP is low.     

Genetics: Genetic analysis prior to selective fetal reduction in multiple pregnancy: technical aspects and clinical outcome

Multiple pregnancies resulting from ovarian stimulation areat a higher risk of carrying at least one fetus affected byMendelian or chromosomal anomalies, the incidence of which isdirectly related to the order of multiples. Genetic analysisbefore fetal reduction was offered to both high-and low-riskpregnant women carrying two or more fetuses after ovulationinduction. Chorionic villus sampling (CVS) and fetal reductionwere achieved by transabdominal needling. The use of short-termculture, the polymerase chain reaction and fresh tissue enzymaticanalyses have made it possible for genetic diagnosis to be availablein a few days. A total of 100 patients had multifetal pregnancyreduction performed by a single operator; all of them completedpregnancy and none was lost at follow-up. The total fetal lossbefore 24 weeks was 7% and no statistically significant relationshipwas found with the final number of fetuses and CVS. Perinatallosses (3.9%) were only present in the series with a final numberof two fetuses. Pregnancy duration and birthweight were significantlyhigher in singletons than in twins, but were not related toCVS. The rate of chromosomal disorders was higher (7.2%) inthe study series than in singleton pregnancies not undergoingfetal reduction. Diagnostic error due to incorrect samplingwas reported in 1.5% of cases. These data support fetal reductionas a valuable strategy to improve the outcome of multiple pregnancy.The outcome of pregnancies reduced to singletons was significantlybetter than of those reduced to twins, and was not related toCVS. Therefore, prenatal genetic diagnosis should become anintegral part of counselling on multiple pregnancy, and is stronglyrecommended when reduction to singleton pregnancy is requested.     

腹腔镜在异位妊娠中的诊断和治疗价值

本文分析1982～1987年间收治的544例异位妊娠,其中270例行腹腔镜检查、274例未作腹腔镜检查。两组资料相比提示:腹腔镜检查组诊断符合率高达97.40％;由于能及早明确诊断,故该组腹腔内出血量比未作腹腔镜检查组少,平均为241m1/372ml(P<0.05),需输血例数明显减少30例(11.11％)/134例(48.90％)(P<0.01),输卵管未破裂者增高222例(82.22％)/194例(70.80％)(P<0.01)。270例无术后并发症发生。上述给年轻不孕患者作非手术治疗或输卵管保守手术以保留生育功能提供良好条件。
