Background and Objectives: Vitamin D deficiency is involved in numerous pathologies, including endocrine pathology. The purpose of this review consists of presenting the role of vitamin D in the pathophysiology of certain endocrine disorders, autoimmune thyroid disorders (Hashimoto’s disease and Grave’s disease), diabetes mellitus, and obesity, and whether its supplementation can influence the outcome of these diseases. Materials and Methods: Review articles and original articles from the literature were consulted that corresponded with the thematic. Results: Vitamin D deficiency is frequently encountered in endocrine disorders and supplementation restores the normal values. In Hashimoto’s disease, vitamin D deficiency appears to be correlated with a higher titer of anti-TPO antibodies and with thyroid volume, and supplementation was associated with reduction of antibodies in some studies. In other studies, supplementation appeared to reduce TSH levels. In Grave’s disease, there was a significant correlation regarding vitamin D levels and thyroid volume respective to the degree of exophthalmos. In diabetes mellitus type 2 patients, supplementation led to some improvement of the HOMA-IR index and HbA1c, whereas obesity data from literature do not report significant beneficial findings. Conclusions: Vitamin D deficiency is highly prevalent in endocrine disorders and its supplementation appears to have numerous beneficial effects.

Congenital diaphragmatic hernia is an abnormality of embryologic development characterized by the persistence of communication between the thoracic and abdominal cavities, followed by an extremely high death rate despite medical progress. In Bihor county, according to a retrospective analysis of patient records from the Regional Center of Genetics, 30 children were diagnosed with congenital diaphragmatic hernia over a span of 28 years, from 1990 to 2018, most being male (73.3%). Predominant were the complex congenital diaphragmatic cases, meaning the cases of diaphragmatic hernia associated with other congenital abnormalities, 67% (20 patients) presenting at least one other congenital malformation. 95% (19 cases) of patients with complex congenital diaphragmatic hernia presented pulmonary abnormalities, the most frequent being pulmonary hypoplasia; 35% (7 cases) presented cardiac abnormalities. The Apgar score at 5 minutes after birth was significantly lower for patients with the clinical form of complex congenital diaphragmatic hernia. The mortality for the patients presenting the complex form was 100%, and for the patients presenting the isolated form was 20%. Karyotype analysis was performed for 17 patients, and 23.53% of them (4 patients) presented chromosomal abnormalities.

Introduction. Chronic kidney disease is a common comorbidity in diabetes mellitus type 2 patients because of presence of numerous risk factors such as obesity, hypertension, hyperglycemia and dyslipidemia. Material and methods. Our retrospective, observational study included 300 patients with type 2 diabetes mellitus from Bihor County and had the purpose to establish a clinical profile and to determine the risk factors associated with this pathology. Results. The prevalence of CKD was 75.67%. Older age, worse glucose control, presence of diabetic polyneuropathy and diabetic retinopathy, higher weight, past history of cardiovascular events, the presence of metabolic syndrome and hyperuricemia were associated with the presence of CKD. Conclusion. The clinical characteristics of type 2 diabetes mellitus patients with CKD is significantly worse compared with the population without CKD.
