Cannabinoids and PPAR Ligands: The Future in Treatment of Polycystic Ovary Syndrome Women with Obesity and Reduced Fertility.

Cannabinoids (CBs) are used to treat chronic pain, chemotherapy-induced nausea and vomiting, and multiple sclerosis spasticity. Recently, the medicinal use of CBs has attracted increasing interest as a new therapeutic in many diseases. Data indicate a correlation between CBs and PPARs via diverse mechanisms. Both the endocannabinoid system (ECS) and peroxisome proliferator-activated receptors (PPARs) may play a significant role in PCOS and PCOS related disorders, especially in disturbances of glucose-lipid metabolism as well as in obesity and fertility. Taking into consideration the ubiquity of PCOS in the human population, it seems indispensable to search for new potential therapeutic targets for this condition. The aim of this review is to examine the relationship between metabolic disturbances and obesity in PCOS pathology. We discuss current and future therapeutic interventions for PCOS and related disorders, with emphasis on the metabolic pathways related to PCOS pathophysiology. The link between the ECS and PPARs is a promising new target for PCOS, and we examine this relationship in depth.

[Assessment of the quality of life in patients with differentiated thyroid carcinoma during a one-month withdrawal of levorotatory thyroxine preparations (L-T4) before a control diagnostics]. / Ocena jakosci zycia (QL) chorych ze zróznicowanym rakiem tarczycypodczas miesiecznej przerwy w przyjmowaniu preparatówlewoskretnej tyroksyny (L-T4) przed diagnostyka kontrolna.

INTRODUCTION: Monitoring of patients with differentiated thyroid carcinoma consists of a periodic control for thyroglobulin (Tg) concentration and radioiodine diagnostics during stimulation of endogenous TSH. Application of recombinant TSH is an alternative procedure which considerably increases cost of diagnostics but allows to avoid symptoms of hypothyreosis. This work was aimed at evaluating the influence of a withdrawal of L-T4 preparations preceding the control diagnostics on the quality of life in patients. MATERIAL AND METHODS: Investigation was performed in a group of 131 patients [115 women (87.75%) and 16 men (12.25%)] with differentiated thyroid carcinoma admitted for a periodic control diagnostics that included neck ultrasonography and an evaluation of Tg concentration, wholebody scintigraphy following a stimulation of endogenous TSH after a one-month break in taking L-T4 preparations. Research was conducted with a prepared questionnaire assessing several basic determinants of the quality of life on a 6-degree scale. RESULTS: During hypothyreosis quality of life in patients with differentiated thyroid carcinoma is worsened. The frequency and volume of symptoms increased twice. CONCLUSIONS: 1. One-month gap in taking L-T4 is associated with a significant deterioration of the quality of life in tested patients. 2. The symptoms are especially strongly expressed in the elderly. 3. Administration of recombinant TSH (rhTSH) for a control diagnostics may permit the patients with differentiated thyroid carcinoma to avoid a deterioration of the quality of life.
