Introduction: Melasma is a common acquired hypermelanosis seen mainly in women which occurs on the sun-exposed skin of the face. The exact cause of melasma is unknown. The majority of the cases are attributed to pregnancy, combined oral contraceptive pills, genetic factors, sun exposure, use of cosmetic products, thyroid disorders and anti-convulsant drugs. This study was performed to evaluate ...

The concept of decision-aiding ranges were introduced to improve diagnostic efficiency. The clinical uncertainty in distinguishing borderline cases of hyperthyroidism and hypothyroidism among 1559 consecutive requests for thyroid function tests was 47%. This was reduced to 22% by using the free thyroxine index and to under 2% by using specific tests determined by the decision-aiding ranges.

thyroid hormones regulate the metabolisms of all cells including hepatocytes, and hence, modulate hepatic function. hyperthyroidism is one of the most common endocrine disorders characterized by increased secretion of thyroid hormones t3 and/or t4. this study investigated frequency of abnormal liver function tests in the patients with hyperthyroidism that referred to imam reza hospital of kerma...

conclusions ipah is associated with subclinical hypothyroidism and low patient functional capacity, and is more common in rv failure. results in this research, 84.8% of the participants were women. the mean pap was 51.6 mmhg (31-87) and mean thyroid stimulating hormone (tsh) level was 4.2 miu/ml (0.7 - 10). subclinical hypothyroidism was detected in 26 patients (49.1%). there were significant c...

Background: Thyroid function disorders, particularly congenital hypothyroidism (CHT), are important endocrine dysfunctions associated with permanent morbidities. CHT is more prevalent among preterm low-birth-weight neonates compared to term infants with normal weight. Methods: This prospective cohort study was conducted on 126 very-low-birth-weight (VLBW) neonates referred to the neonatal inten...

A normal pregnancy results in a number of important physiological and hormonal changes that alter thyroid function. These changes mean that laboratory tests of thyroid function must be interpreted with caution during pregnancy. Levels of thyroxine binding globulin (TBG) and production of T3 and T4 hormones and the daily requirement of iodine in pregnancy are increased to 50%, TSH receptor stimu...
