Proposed diagnostic thresholds for gestational diabetes mellitus according to a 75-g oral glucose tolerance test. Maternal and perinatal outcomes in 3260 Danish women.

AIMS: To study if established diagnostic threshold values for gestational diabetes based on a 75-g, 2-h oral glucose tolerance test can be supported by maternal and perinatal outcomes. METHODS: Historical cohort study of 3260 pregnant women examined for gestational diabetes on the basis of risk indicators. Information on oral glucose tolerance test results and clinical outcomes were collected from medical records. RESULTS: There was an increased risk of delivering a macrosomic infant in women with 2-h capillary blood glucose of 7.8-8.9 mmol/l compared with women with 2-h glucose < 7.8 mmol/l. Despite treatment, 2-h glucose of 9.0-11.0 mmol/l and > or = 11.1 mmol/l were both associated with increased rates of macrosomia, spontaneous preterm delivery, hypertensive complications, and neonatal hypoglycaemia. Adverse outcomes tended to be more frequent in women with 2-h glucose > or = 11.1 mmol/l than in women with 2-h glucose of 9.0-11.0 mmol/l. CONCLUSIONS: The risk for several maternal and perinatal complications increased with the diagnostic threshold for 2-h glucose. Large-scale blinded studies are needed to clarify the question of a clinically meaningful diagnosis of gestational diabetes mellitus. Until these results are available, a 2-h threshold level of 9.0 mmol/l after a 75-g oral glucose tolerance test seems acceptable.     

手部皮肤套脱伤的治疗

目的探讨手部皮肤套脱伤的治疗方法。方法2002年4月-2004年11月，治疗22例手部皮肤套脱伤患者，其中19例分别通过吻合血管、套脱皮肤修薄回植及多切口引流等方法进行修复。另有3例，因无法行套脱皮肤回植而采用腹部带蒂皮瓣修复。结果术后随访3个月-1年。19例套脱皮肤原位回植患者中，13例皮肤完全成活，4例有部分皮缘坏死，经中药换药后愈合，2例行切痂植皮术后治愈。手功能按ATN功能评分评定：优9例，良7例，中3例，优良率为84％，患者对手外形及功能满意。3例腹部皮瓣修复者，皮瓣全部成活。术后随访5个月-1年，手外形及功能明显差于皮肤原位回植者。结论尽可能地回植手部套脱皮肤，对手功能及外形的恢复具有重要意义。     

交锁髓内钉治疗下肢长管状骨骨折的效果

①目的 探讨交锁髓内钉治疗下肢长管状骨骨折的效果。②方法 应用交锁髓内钉治疗下肢长管状骨骨折56例，随访8～26个月，观察治疗结果。③结果 56例病人术后对位、对线均满意，股骨骨折平均愈合时间为19．9周，胫骨骨折平均愈合时间为17．7周，2例延迟愈合。无主钉或锁钉断裂．无肢体短缩、功能障碍发生。④结论 交锁髓内钉是治疗下肢长管状骨骨折的一种理想、可靠的内固定方法，其疗效满意，值得临床推广应用。     

Successful triplet pregnancy in a patient with a unicornuate uterus with a cavitary communicating rudimentary horn

In a patient with primary infertility, ovulation was inducedby monitored stimulation with human menopausal gonadotrophins(HMG) because of polycystic ovarian disease. Infertility work-uphad shown a unicornuate uterus with a cavitary communicatingrudimentary horn. The husband showed a varicocele-related moderateoligoasthenoterato-zoospermia. A triplet pregnancy occurredin a third HMG ovulation induction cycle combined with intra-uterineinsemination of the husband's washed semen. The pregnancy wascarefully monitored, and measures to prevent premature deliverywere taken. Because of the patient's obvious discomfort in thepresence of premature labour, Caesarean section was performedat 33 weeks gestation and three healthy infants were delivered.This is the first report of a successful triplet pregnancy ina women with a unicornuate uterus. The reproductive and obstetricoutcome of this condition in general, and in the case of multiplepregnancy, is discussed.     

Five-Year Outcome After Epilepsy Surgery in Nonmonitored and Monitored Surgical Candidates

Summary: Purpose : We wished to compare outcome 5 years after temporal lobectomy in 28 patients selected for surgery on the basis of interictal EEG patterns with that in 46 patients who underwent EEG-video monitoring studies as part of their preoperative evaluation during the same era.
Methods : The 28 nonmonitored patients had interictal EEG patterns that demonstrated a consistent, unilateral, anterior-midtemporal epileptiform focus, without discordant findings from other studies. Outcomes were assessed for years 4 and 5 after operation.
Results : Twenty-six of 28 (92.9%) nonmonitored patients were seizure-free or had at least 75% reduction in seizures. Twenty-nine of 46 (63.0%) monitored patients were seizure-free or had at least 75% reduction in seizures. Preoperative interictal EEGs of 29 of these patients showed independently localized bitemporal, ex-tratemporal, midposterior temporal, or diffuse epileptiform patterns. The remaining 17 monitored patients had preoperative strictly unilateral anterior-midtemporal interictal discharges, and their outcome was comparable to the nonmonitored group, with 15 (88.8%) seizure-free or with at least 75% reduction in seizures.
Conclusions : A proportion of candidates for epilepsy surgery can be selected without ictal recordings provided that interictal EEGs demonstrate consistent unilateral anterior-midtemporal epileptiform discharges and that other data are not discordant.     

Measurement of diet in a large national survey: comparison of computerized and manual coding of records in household measures

A diary method using household measures was employed to obtain dietary records in a large national prospective survey and a computer program, DIDO (Diet In Data Out), was designed for direct entry of the diaries. The accuracy of this computerized coding system was examined alongside that of the manual coding used for a similar diary in a previous wave, 7 years earlier, of the same survey. Accuracy was assessed by analysis of the errors in the coded and checked records by stringent re-checking of nominal 2% random subsamples of the diet diaries coded by each method. The mean time to code and check each of the 2086 7-day records in the whole survey using DIDO was 58 minutes (SD 30) compared with reported results of 1–4 hours for manual methods. The mean error rate of computerized coding and checking with DIDO was 2.3% (SD 2.1; range 0–8.9) per diary in the subsample. Correcting these mistakes made insignificant changes to the calculated mean energy and nutrient intakes for the subsample. The percentage of individuals changing to an adjacent third of nutrient distribution after correcting unambiguous errors ranged from none (for alcohol) to 11% (for carbohydrate and calcium intake). The mean error rate on a similar subsample of diaries from the earlier survey which had been coded manually was significantly higher at 5.9% (SD 4.1; range 0–17) per diary. Emphasis is laid on the importance, in coding, of dealing with ambiguities in the subjects' records, since this can affect the accuracy and the precision of the nutrient results obtained. We conclude that the DIDO coding method has the advantages of greater accuracy, speed, consistency and efficient data handling, and affords greater data accessibility for checking, compared with manual systems.     

Prenatal lead exposure in relation to gestational age and birth weight: A review of epidemiologic studies

Although the adverse effect on pregnancy outcomes at high levels of lead exposure in the workplace has been recognized for years, there is uncertainty regarding the impact of exposure at the lower community exposure levels commonly encountered today. This review summarizes the epidemiologic literature and discusses pertinent methodologic issues and possible sources of interstudy variation. The authors conclude that prenatal lead exposure is unlikely to increase the risk of premature membrane rupture but does appear to increase the risk of preterm delivery. Whether prenatal lead exposure decreases gestational age in terms of infants is unclear. Prenatal lead exposure also appears to be associated with reduced birth weight, but results vary in relation to study design and degree of control for confounding. Adjustment for gestational age, a possible confounder of the birth weight-lead exposure association, did not yield clearer results.
