To identify clinical and laboratory data which differentiate Klinefelter syndrome (KS) patients according to age group.The study included all cases of hypogonadism, gynecomastia and/or infertility whose karyotype was performed at a university hospital from January 1989 to December 2011, in a total of 105 subjects. The following data were retrospectively analyzed: age at first visit, ratio of arm span to height, pubic hair, gynecomastia, testicular volume, luteinizing hormone (LH), follicle stimulating hormone (FSH), total testosterone (T), and spermiogram.During the study period, 33 patients were diagnosed with Klinefelter syndrome (KS+) and 72 were not (KS-). Out of all KS cases, only seven (21.2%) were diagnosed before 20 years old and two (6.1%) before 10 years old. Age at first consultation (in years) was similar in both groups (KS+ = 31.3±12.9 and KS- = 27.6±12.1), as were ratio of arm span to height and frequency of gynecomastia. However, in KS+ patients, pubic hair was less developed, testicular volume was smaller and testosterone levels were lower, while LH and FSH levels and frequency of azoospermia were higher.Klinefelter syndrome is both an under and late diagnosed condition. The most important data for diagnosis are testicular volume, hormone levels and presence of azoospermia in spermiogram, especially in puberty and adult life.

Purpose To expand on prior (often contradictory) research implicating maternal infection as a cause of preterm birth, specifically exploring whether bacterial vaginosis (BV) in pregnancy caused preterm birth in a sample of 103 women in a rural Mississippi obstetric-gyneco-logic clinic. Data Sources This descriptive correlational study explored the relationship between BV and preterm birth, using retrospective chart data from a purposive sample of 103 women (for a power level of 95%) from one rural obstetric-gyneco-logic clinic. Conclusions Contrary to the majority of published research, this study did not find a positive correlation between BV and preterm birth. This unexpected result raises questions, particularly given that the preponderance (86%) of women who tested positive for BV during their pregnancy were African American, a population in which both BV and preterm birth are more prevalent. Implications for Practice Whether to screen for BV in pregnancy is a clinically important question not only in terms of the health of mother and child but also in terms of responsible use of resources. Clear findings supporting beneficial health results for screening would dictate screening regard-less of the cost. But research continues to lack consensus on the efficacy of BV screening during pregnancy in preventing adverse pregnancy outcomes. In this study, as in some of the literature, the risk of preterm birth did not correlate positively with BV during pregnancy. In the absence of that correlation, cost gains importance. Nurse practitioners (NPs) must use resources wisely, including time, laboratory tests, and medications. Although some specialists recommend screening or treating all pregnant patients for BV, the current practice of not screening or treating all pregnant patients seems warranted until definitive findings establish a conclusive correlation between BV and preterm birth.
