A prospective study of Toxoplasma-positive pregnant women in southern Brazil: a health alert

We evaluated anti-Toxoplasma gondii IgM-reactive pregnant women seen at a high-risk pregnancy outpatient clinic. From March 2005 to January 2008 in Paraná, Brazil, pregnant women seen by the Brazilian Public Health System, in any gestational period, who were anti-T. gondii IgM-positive, were followed. Clinical symptoms were noted, and tests performed including IgA, IgG avidity, ultrasonogram, and amniocentesis (PCR/inoculation in mice). Of 75 patients, 8 showed low, 3 intermediate and 31 high IgG avidity. Of those who underwent the avidity test, 31 (70.5%) were in the second trimester of pregnancy. Thirty-two (42.7%) pregnant women received specific treatment. Six received triple combination treatment; in three, tachyzoites were isolated, although only one was PCR-positive, showing changes in the cerebral sonogram, borderline IgA, and the Sabin tetrad. One fetus died, and one non-reactive IgM pregnant woman showed ocular recurrence. The municipality of residence, contact with cats during adulthood, and ingestion of unpasteurized milk were shown to be important risk factors. Congenital toxoplasmosis was observed in a pregnancy referred late for treatment. Follow-up of children born to mothers with diagnosed or suspected acute toxoplasmosis is crucial in the management of the changes that toxoplasmosis may cause.     

体重质量指数与557例绝经后妇女骨密度变化的关系研究

目的 了解不同的年龄绝经后妇女不同体重质量指数(BMI)与不同部位骨密度(BMD)的关系。方法 来自门诊健康体检的557名绝经后妇女(肝肾等疾病除外),年龄范围50~78岁。用双能X线吸收法(DEXA)测定腰椎(L2-4)、股骨颈、Ward's三角及Troch等部位的BMD,同时计算BMI。根据BMI将研究对象分为3组:低体重组(BMI≤20 kg／m2)、正常体重组(25≥BMI>20 kg/m2)及超重组(BMI>25 kg/m2)。根据年龄又分为3组(50-,60-,70~78岁),用方差分析的方法进行各组间均数的统计学分析。结果不同BMI组总体不同部位的BMD方差分析比较有极显著意义P<0.01,高BMI组的BMD均值明显增高;进一步对同一年龄组不同BMI组的不同部位的BMD均值比较,各组之间均有显著性差异(P<0.01),特别是低体重组的骨密度明显低于其他两组BMI组的BMD。结论BMI与绝经后妇女的骨密度有显著相关,但低体重的绝经后妇女作为骨折的危险人群应受到更多的关注:对于超重的绝经后妇女,通过增加体重的方式增加BMD是危险的,因为超重与高血压、冠心病、糖尿病、心肌梗死及中风有一定的关系;通过其他途径:如年轻时加强运动、多饮牛奶、不盲目减肥等,提高妇女峰值骨含量是非常重要的。     

17β-雌二醇对子宫内膜异位症患者在位子宫内膜间质细胞β-catenin mRNA和蛋白表达的影响

目的研究17β-雌二醇(17β-E2)对子宫内膜异位症(内异症)患者在位子宫内膜间质细胞β-catenin mRNA和蛋白表达的影响,探讨Wnt/β-catenin信号通路在介导雌激素促进内异症发生发展的作用。方法体外分离培养内异症患者在位子宫内膜间质细胞。用不同浓度17β-E2处理子宫内膜间质细胞48 h;此后选用10-10mol/L 17β-E2处理子宫内膜间质细胞12、24和48 h,逆转录聚合酶链反应(RT-PCR)和免疫印迹法(Western blotting)检测17β-E2处理前后子宫内膜间质细胞β-catenin mRNA和蛋白的表达水平。同法分析雌激素受体拮抗剂ICI182,780(10-6mol/L)对17β-E2促进β-catenin mRNA和蛋白表达的影响。免疫组织化学染色观察17β-E2作用后β-catenin在子宫内膜间质细胞中的定位。结果17β-E2能明显促进内异症患者在位子宫内膜间质细胞β-catenin mRNA和蛋白的表达,并呈剂量和时间依赖性,于10-10mol/L作用48 h最明显。雌激素受体拮抗剂ICI182,780能明显抑制17β-E2对子宫内膜间质细胞β-catenin mRNA和蛋白的表达。免疫组织化学染色发现17β-E2能促进β-catenin在子宫内膜间质细胞核内的表达。结论雌激素可能通过激活Wnt/β-catenin信号通路促进内异症在位子宫内膜的异位种植。     

Case of acute urinary retention as a result of non-steroidal anti-inflammatory drugs

Abstract:   A 19-year-old woman presented at our hospital with acute urinary retention in September 2005. She had experienced the same chief complaint twice previously. She had used non-steroidal anti-inflammatory drugs before acute urinary retention. The results of physical examinations were unremarkable, and her neurologic signs were not remarkable. The basic laboratory test values were all normal and a psychiatric assessment indicated that her symptoms were not psychogenic. Magnetic resonance imaging was carried out, but revealed only a slight bulging in the L3/L4/L5 disk. Water cystometry showed acontractile detrusor. We made a diagnosis of acute urinary retention as a result of non-steroidal anti-inflammatory drugs because of her use of such drugs before the development of symptoms on multiple occasions. This patient was regularly followed up as an outpatient, and she could void smoothly in February 2006. This is the first report which acute urinary retention associated with non-steroidal anti-inflammatory drugs in Japan.     

Pharmacokinetics of orally administered norethisterone enanthate in rabbit, monkey, and women

Norethisterone enanthate (NET-En), an established intramuscular long-acting contraceptive agent, has previously been shown to be effective in inhibiting fertility in two rodent species even 4 days after oral ingestion. Pharmacokinetics of NET and NET-En were studied after oral and intramuscular doses in two animal species and a few women. The results suggest that the NET-En was absorbed within a day in all the species after oral dose. The estimates of relative bioavailability ranged from 13 to 51% in rabbits, monkeys, and women. The elimination half-life was 5–10 days. The presence of the active component, NET, in the circulation over the experimental period of 15 days suggests that NET-En could be useful as a long-acting oral pill. The suppression of progesterone levels during the luteal phase of menstrual cycle in women also supports this finding.     

Diminished effect of etidronate in vitamin D deficient osteopenic postmenopausal women

Objective: The effects of vitamin D deficiency in osteopenic postmenopausal women treated with intermittent cyclical etidronate have been studied. Bone mass and biochemical parameters as bone markers were measured before and after one year of therapy with intermittent cyclical etidronate. Results: In 30 patients without vitamin D deficiency, bone mass in the lumbal spine and femoral neck was significantly increased compared to 28 vitamin D deficient patients. After cyclical intermittent etidronate therapy, serum osteocalcin and PTH were significantly increased in the vitamin D deficient patients, whereas in non-vitamin D deficient patients they did not change. Conclusion: It is worthwhile measuring serum vitamin D before starting etidronate therapy and, in case of deficiency, to give vitamin D.

Resiliency and Adult Adaptation in Women with and Without Self-Reported Histories of Childhood Sexual Abuse

This study investigated the relationship of protective factors (PF) to adult adaptation in a nonclinical sample consisting of 264 undergraduate women: two groups without childhood sexual abuse (CSA), high (n = 109) and low (n = 99) on PF; and two groups with CSA, high (n = 17) and low (n = 27) on PF. The first hypothesis that higher levels of PF would be significantly associated with higher levels of functioning for all individuals was supported by the data. The second hypothesis that the women with CSA and higher levels of PF would appear similar in adaptation to those without CSA was also supported. The findings further suggest that though the protective factors were beneficial for most individuals, they were significantly more helpful for those with CSA.     

Changing prevalence and knowledge of urinary incontinence among Hong Kong Chinese women

A territory-wide telephone survey was conducted in Hong Kong to assess the prevalence, knowledge, and treatment-seeking behaviour of Chinese women with urinary incontinence, using validated Chinese version of Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7). Women, 540, aged between 17 to 77 years were interviewed. Of the respondents, 40.8% reported stress urinary incontinence, 20.4% had urge incontinence and 15.9% had mixed incontinence. Among these, 16.0% reported quality of life impairment; 9.3% felt frustrated with low morale, and 15.2% had nervous and anxiety problems. However, as many as 78.3% of the respondents did not know that stress urinary incontinence is a disease entity, and 60.6% thought that leakage of urine was a normal aging process. For those respondents having stress urinary incontinence, the first treatment of choice was physiotherapy. The second choice was medication, and surgical treatment was the last option. Respondents with stress urinary incontinence showed higher education level.
