BACKGROUND We set out to determine the prevalence of incidental intracranial aneurysms in first-degree relatives aged 30 years or more of people with intracranial aneurysms, and to see if polycystic kidney disease contributes to the aggregation of familial intracranial aneurysms. METHODS 91 families with two or more affected members had previously been identified from a 14 year series of 1150...

Polycystic liver disease rarely occurs in isolation as part of autosomal dominant polycystic liver disease, but more commonly, it exists as an extra-renal manifestation of autosomal dominant polycystic kidney disease. The pathogenesis of polycystic liver disease involves defects in the primary cilium of the cholangiocyte, with genetic mutations that impair key proteins integral to the complex f...

BACKGROUND There is growing acceptance that polycystic ovaries are an important marker of polycystic ovary syndrome (PCOS) despite significant variability when making the ultrasound diagnosis. To better understand the nature of this variability, we proposed to evaluate the level of inter-observer agreement when identifying and quantifying individual ultrasonographic features of polycystic ovari...

BACKGROUND The incidence of invasive cancer within a mucinous cystic neoplasm of the pancreas varies between 6 and 36%. Polycystic ovarian syndrome is a disorder characterized by hyperandrogenism and anovulatory infertility. One surgical treatment that can restore endocrine balance and ovulation in polycystic ovarian syndrome is partial ovarian destruction. Successful pregnancies following prec...

BACKGROUND Metformin is effective for the treatment of polycystic ovary syndrome, but conflicting results regarding its effect on adipocytokine levels (adiponectin, resistin, visfatin, and leptin) in patients with polycystic ovary syndrome receiving metformin treatment have been reported. To provide high-quality evidence about the effect of metformin treatment on adipocytokines in patients with...

OBJECTIVE The association between polycystic ovarian syndrome and increased cardiovascular disease risk is still a controversial issue. In light of data documenting some common pathways or common end-points, the present study was undertaken to determine whether there is a relationship between sleep blood pressure pattern disturbances and polycystic ovarian syndrome in young women. METHOD The ...

OBJECTIVE: To study the feasibility of making an early diagnosis of adult polycystic kidney disease by using genetic linkage analysis in Hong Kong. DESIGN: Genetic linkage study. SETTING: University teaching hospital, Hong Kong. PARTICIPANTS: Six members of a Chinese family with a history of adult polycystic kidney disease. MAIN OUTCOME MEASURES: The inheritance pattern of adult polycystic kidn...

OBJECTIVE To compare lipid profile in lean and obese women with polycystic ovary syndrome with normal weight and obese controls. METHOD The case-control study was conducted at the Department of Chemical Pathology, Liaquat National Hospital, Karachi, from March 2006 to April 2007. It comprised 50 cases of polycystic ovary syndrome along with 50 healthy controls matching for age, gender and wei...

We investigated aromatization and the mechanism of action of epidermal growth factor (EGF) and transforming growth factor alpha (TGFalpha) on oestradiol biosynthesis in freshly prepared granulosa cells from polycystic ovaries. Freshly prepared granulosa cells from polycystic ovaries incubated for only 3 h under basal conditions secreted significantly (P< 0.001) greater amounts of oestradiol-17b...

Due to genetic heterogeneity and variable diagnostic criteria, genetic studies of polycystic ovary syndrome are particularly challenging. Furthermore, lack of sufficiently large cohorts limits the identification of susceptibility genes contributing to polycystic ovary syndrome. Here, we carried out a systematic search of studies deposited in the Gene Expression Omnibus database through August 3...
