Conjoined twins represent the most uncommon twinning mechanism in humans, with an incidence approaching 1:100,000 deliveries. Although several conjoined male twins have occasionally been reported, for unexplained reasons most cases of conjoined twins are female. Of all the female conjoined twin sets either documented by medical authorities or referenced in ancient literary sources, in only one case were pregnancy and delivery successfully achieved by the conjoined twins themselves. We describe the highly unusual circumstance of the Blažek sisters, an extreme developmental example of the terminal monogenital pygopagus type of conjoined twins in which one of the joined sisters conceived and underwent labor and childbirth. Although little information is known about their own birth, these conjoined twins paradoxically hold a unique place in the history of obstetrics. Information from formal anatomic examinations of the sisters and their exploitative circus exhibitions is outlined with a view to explain relevant reproductive events. We present the sensational conception, pregnancy course, and subsequent vaginal delivery of a healthy male infant as summarized from contemporary sources. Additionally, the significance of pygopagus twins is discussed with regard to other types of monozygous twinning. Although modern operative techniques have been a welcome advance in the science of conjoined twin separation, the Blažek case is another reminder that, even in the era before complex surgery, conjoined twins were not necessarily consigned to an incomplete reproductive career.

Objective: There are limited data on cardiometabolic risk factors and the prevalence of metabolic syndrome (MetS) across the different PCOS phenotypes in Caucasian population. Lipid accumulation product (LAP) is a clinical surrogate marker that could be used for evaluation of MetS in clinical practice. The aim of the study was to analyze metabolic characteristics and the ability of LAP to predict MetS in different PCOS phenotypes. Design: Cross-sectional clinical study analyzing 365 women with PCOS divided into four phenotypes according to the ESHRE/ASRM criteria, and 125 healthy BMI-matched controls. Methods: In all subjects, LAP was determined and MetS was diagnosed according to the National Cholesterol Education Program/Adult Treatment Panel III (NCEP-ATP III), the International Diabetes Federation (IDF) and the Joint Interim Statement (JIS) criteria. Logistic regression and ROC curve analyses were used to determine predictors of MetS in each PCOS phenotype. All analyses were performed with age and BMI adjustment. Results: All PCOS phenotypes in comparison to controls had higher prevalence of MetS assessed by NCEP-ATP III criteria, and only classic phenotypes when IDF and JIS criteria were used. All phenotypes had the same prevalence of MetS irrespective of used definition. LAP and exhibited the highest diagnostic accuracy and was an independent predictor of MetS in all phenotypes. Conclusion: LAP is an independent and accurate clinical determinant of MetS in all PCOS phenotypes in our Caucasian population. All PCOS phenotypes, including non-classic ones, are metabolically challenged and with cardiovascular risk, particularly phenotype B. © 2016 The authors Published by Bioscientifica Ltd.
