Background: Single nucleotide polymorphism of the follicle-stimulating hormone (FSH) receptor (FSHR) is an important marker of ovarian function. However, its role in female fecundity remains debatable. The aim of the study to assess the relationship of FSHR polymorphism of Serine/Serine, Asparagine/Asparagine and Asparagine/Serine variants directly against the time-to-pregnancy (TTP) in women.

Objective: The objective of this study was to evaluate impact of periodontal surgery on periodontal health and on glycaemia control of type 1 and type 2 (T1DM; T2DM) diabetics with severe periodontitis, during 12 months follow-up, in comparison with non-diabetic controls.

Materials And Methods: A total of 23 T1DM and 10 T2DM patients with respective number of matched non-diabetics were examined prior to, and 3, 6 and 12 months after periodontal surgery. Glycosylated haemoglobin (HbA1c) reflected control of DM.

Turner syndrome is a rare genetic disorder which impairs women's growth, reproductive function, cardiovascular development and other functions. This syndrome has been proposed as an independent risk marker for cardiovascular disease. Despite this, life-threatening cardiovascular outcomes affecting young women are dismissed because of incomplete follow up.

Introduction: Although diabetes may not be associated with psychopathology, it may be associated with less severe disturbances in psychosocial functioning. Emotional problems in relation to type 1 diabetes are usually analysed as symptoms of psychiatric conditions but not as states of mood. The aim was to compare profiles of mood states in adult patients with childhood-onset and adulthood-onset type 1 diabetes mellitus and to outline possible gender-specific differences.

Background: The purpose of this study was to evaluate associations between diabetes mellitus - related factors and periodontal parameters among adult patients with diabetes mellitus, with respect to type of diabetes.

Methods: Study participants were 179 randomly selected 18-62-year-aged patients with type 1 diabetes mellitus and 87 randomly selected 32-70-year-aged patients with type 2 diabetes. Metabolic control of diabetes was determined by the values of glycosylated haemoglobin (HbA1c).
