Tension-free vaginal tape for the treatment of urodynamic stress incontinence with intrinsic sphincteric deficiency

The purpose of this study was to evaluate the outcome of tension-free vaginal tape (TVT) procedure in women with urodynamic stress incontinence diagnosed as having intrinsic sphincteric deficiency (ISD). The combination of a maximal urethral closure pressure <20 cm H₂O and a Valsalva leak point pressure <60 cm H₂O was considered as diagnostic of ISD. Subjects with detrusor overactivity on preoperative urodynamics were excluded. A total of 35 patients with both low closure pressure and leak point pressure were enrolled. Bladder perforation occurred in three (8.6%) cases. Postoperative urinary voiding difficulties occurred in nine (25.7%) women. Two patients underwent surgical detension of the tape, with complete resolution of urinary retention and no relapse of incontinence. Women with postoperative voiding dysfunction had a significantly lower detrusorial pressure at the peak flow on preoperative urodynamics compared to those who voided efficiently after TVT. The mean (range) follow-up time was 12.5 months (3–36). The objective cure rate for stress incontinence was 91.4%. Two of the three (66%) patients in whom the TVT procedure failed had a fixed urethra. De novo urge incontinence was found in five (14.3%) patients.

Bone disorders following total gastrectomy

Bone disorders following gastrectomy were studied by measuring absolute and relative bone mineral density of the Wards triangle, serum 1,25-(OH)₂-D, alkaline phosphatase, and total serum calcium. The subjects were 20 males who had undergone total gastrectomy not more than three months previously (group A₁). Seventeen of these patients were reviewed three years later (group A₂). Absolute and relative bone density were significantly lower in group A₂ than in A₁ (0.52 ± 0.011 g/cm² versus 0.6 ± 0.014 g/cm²,P<0.01 and 85.5 ± 1.4% age-matched control versus 95 ± 1.3%,P<0.01). 1,25-(OH)₂-D was significantly lower in group A₂ than in group A₁ (14.3 ± 0.97 pg/ml versus 20.6 ± 1.02 pg/ml,P<0.01). There was no difference in alkaline phosphatase and calcium serum concentration. The mean weight loss was 6.26 ± 0.57% over the follow-up period, and weight loss correlated with absolute and relative bone density (r=–0.74,P<0.01). There was a positive correlation between 1,25-(OH)₂-D and absolute or relative bone density (r=0.67,r=0.62 andP<0.01). These data suggest that bone density decrease has already occurred three years after total gastrectomy and is positively correlated to 1,25-(OH)₂-D deficiency. As no differences in serum alkaline phosphatase and serum calcium concentration were found, these factors are of little value for the early detection of postgastrectomy bone disorders, whereas weight loss is a valuable screening parameter.     

乙二胺四乙酸铁钠强化酱油改善贫血效果观察

本研究比较了NaFeEDTA强化酱油、硫酸亚铁 (FeSO4)强化酱油对IDA改善效果。将 30 0名IDA学生分为对照组、NaFeEDTA强化酱油组Fe 5mg (人·日 )、FeSO4强化酱油组Fe5mg (人·日 ) ,比较新型铁强化剂 (NaFeEDTA)与传统铁剂 (FeSO4)对缺铁性贫血的改善作用。结果表明 ,对照组各项检验指标干预前后没有显著差异。其它各试验组呈现出较为一致的变化 ,表现为血红蛋白、血清铁、血清铁蛋白含量的显著性增加和原卟啉、总铁结合力、转铁蛋白的显著性下降。试验结果提示 ,乙二胺四乙酸铁钠与传统铁剂 (硫酸盐铁 )强化酱油均有改善学生贫血的作用 ,并且NaFeEDTA组的贫血改善率和Hb恢复水平优于FeSO4组。     

广西毛南族农村妇女铁营养状况调查

对450名广西环江县毛南族农村育龄妇女进行血清铁蛋白(SF)、红细胞游离原卟啉(FEP)及血红蛋白(Hb)3项铁指标测定.结果发现:铁缺乏症患病率为27.8%(其中ID4.2%,IDE 7.8%,IDA 15.8%).随着孕次或产次的增加,血红蛋白水平逐渐下降,铁缺乏症患病率逐渐增高.有妊娠或分娩史的妇女与未孕或未生育的妇女血红蛋白水平与铁缺乏症患病率比较均有显著性差异(P<0.05).

Is there a ‘Basque’ profile regarding autosomal recessive deficiencies of coagulation factors?*

When excluding haemophilia and von Willebrand disease, coagulation factors deficiencies constitute rare autosomal recessive disorders (<1 in 500,000) of less precisely defined epidemiology. We have reported herein the distribution of these entities in the French Basque Country, a genetic isolate of very old individualization with peculiar biological specificities. The prevalence of these disorders was markedly high, especially, as already shown, factor XI deficiency. This unusual profile needs to be discussed in the view of population genetics.
