[Several questions of medical treatments in polycystic ovary syndrome]

BAJNOK László

[Polycystic ovary syndrome is an endemic disease, thus its treatment is of great importance. In polycystic ovary syndrome, metformin decreases androgen levels, improves menstrual irregularity, hirsutism, ovulation ratio, and the efficiency of lifestyle interventions on visceral obesity, endothelial function and LDL-cholesterol level. It seems plausible to suppose that metformin decreases the incidence of diabetes in this group of patients. Metformin is superior to oral contraceptives/antiandrogens in respect of its effect on triglyceride level and insulin sensitivity, however, it is less effective in decreasing androgen levels, normalisation of the menstrual cycle and supposedly in the prevention of endometrial cancer. Metformin therapy improves fertility, however, when infertility is the main problem, it is not indicated as the primary treatment. In this case, ovulation induction, ovary drilling, as well as in vitro fertilization are warranted that can be supported by metformin therapy is some cases.]

[The safety of rosiglitazone - Lessons from the RECORD study]

HALMOS Tamás

[The international RECORD study team evaluated the safety of the oral antidiabetic drug rosiglitazone, after contradictory reports of its unfavourable cardiovascular adverse effects, in combination with sulfonyureas and metformin. The drug didn’t increase cardiovascular morbidity and overall mortality compared with standard blood sugar lowering drugs. However, it increased the risk of heart failure, and, in women, the risk of limb fractures. Keeping in mind the strict contraindications, the drug can still be prescribed, as glitazones have effective blood sugar lowering and insulin-sensitizing effects.]

Valproic acid associated pleuropericardial effusion: case report

DEMIR Figen Ulku

Introduction - Valproic acid is an effective antiepileptic and mood stabilizer used in the treatment of many neurological and psychiatric disorders. Although there are frequently seen side effects, effusions between layers of pleural and pericardial membranes are rare to be seen. Case - Pleuropericardial effusion was detected in a 23 years old woman who was under valproic acid treatment because of epileptic seizure. After 1 year of valproic acid treatment, patient complained of dyspnea. As all the researches intended on etiology were usual, valproic acid has been thought to be responsible for the matter. Control examination after 1.5 months regarding the end of treatment revealed complete recovery of pleuropericardial effusion. Discussion - Pleural and pericardial effusions are rarely seen complications related to the use of valproic acid. It must also be kept in mind that valproic acid causes a potential for such side effects which can be blamed etiologically when the other possibilities for patients are excluded.

[The effects of thyroid hormones on bone]

BAJNOK Éva, LAKATOS Péter

[The effects of thyroid hormones on bone tissue are of fundamental importance.They are required for skeletal development and later for normal bone metabolism.Their action is dose-dependent and also depends on the degree of differentiation of the target tissue. In childhood, thyroid hypofunction manifests itself in growth retardation, whereas hyperfunction will accelerate bone maturation.The exact mechanism of action of thyroid hormones on bone in later years is poorly understood, and their clinical relevance on the risk of bone fracture, the most important complication, is also unclear. In adults with hypothyroidism, bone mineral density (BMD) remains unchanged or even becomes increased, but the risk of fractures is elevated. In hyperthyroidism the bone turnover is increased, which may lead to a decrease in BMD and a higher risk of fracture. However, the results are inconsistent for endogenous subclinical hyperthyroidism, where BMD may also decrease and fractures may occur more frequently.Treatment of hypothyroidism may temporarily result in increased fragility but this phenomenon seems to be only transient. During L-T4 replacement therapy the TSH level should be kept in the normal range, while with suppression, it should be set to the lower end of the normal range. During treatment of hyperthyroidism BMD temporarily increases and the risk of fractures decreases.The most effective way of preventing osteoporosis and bone fractures in all cases is the early recognition and treatment of thyroid diseases.The presence of other osteoporosis risk factors should always be considered. In some cases adjuvant therapy may be necessary to stop bone loss.]

[Comparison of different schemes of vitamin D3 therapy]

[Vitamin D plays an important role in several pathways in humans. Its relation with several diseases has been previously de­scribed. Vitamin D deficiency affects al­most the full population on temperate zone at the end of the winter. Recommendations on vitamin D supplementation are inconsistent and there are only a few data about the efficacy of cholecalcipherol given not in daily manner. In the present paper, we examine the different administration mo­dalities, and their efficacy in increasing serum vitamin D levels. High doses administered rarely appear to be equally efficient and safe compared to low doses provided frequently.]
