Catecholamine producing tumors are rare, and their incidence is 2 to 8 cases/million people yearly (2). This disease commonly affects people in their 40s and 50s, but it occurs earlier in people with diseaseassociated germline mutations. Although these tumors are typically sporadic, they are also associated with genetic disorders, including multiple endocrine neoplasia syndrome type 2 (MEN 2). Their symptoms may occur in episodes or paroxysmally and involves a broad clinical spectrum due to the high circulating catecholamine level in plasma. Typical symptoms are tachycardia, pallor, headache, and sweating (3).

This study aimed to evaluate the structural and functional properties of the thyroid gland and to elucidate whether there is any relationship between these and metabolic parameters in patients with NFAI. Material and Methods: Fifty-four patients diagnosed with NFAI and 54 age, gender, and body mass index (BMI) matched healthy controls were included in the study. Free thyroxine (fT4), thyroid-stimulating hormone (TSH), anti-thyroperoxidase antibody (anti-TPO), fasting blood glucose (FBG), fasting insulin level, lipid profiles, C-reactive protein (CRP) levels were estimated in the patients and controls. Furthermore, patients and controls were evaluated by ultrasonography to determine thyroid structure, thyroid volume, and thyroid nodules. Results: The mean total thyroid volume of the NFAI group (13.48±6.3 mL) was significantly higher as compared to that of the control group (13.13±10 mL) (p<0.001). Thyroid nodules were detected in 18 (33.3%) of 54 subjects in the NFAI group and 16 (29.6%) of 54 subjects in the control group, resulting in an insignificant difference (p = 0.836). However, the average number of thyroid nodules was significantly higher in the NFAI group (1.72) compared to the control group (1.06) (p<0.001). The thyroid nodule size of the NFAI group (17.83±9.01 mm) was also significantly larger than the control group (11.68±4.68 mm) (p=0.017). Moreover, a significant association between the thyroid nodule and TSH (p=0.026) and between thyroid nodule size and adenoma size (p=0.046) in the NFAI group was pronounced. Conclusion: In our study, we found that certain parameters related to the thyroid gland, such as thyroid volumes, average number of thyroid nodules, and thyroid nodule sizes, were significantly higher in NFAI patients than in healthy controls. There was no significant difference in terms of thyroid functions and thyroid nodule frequency. In this regard, studies with larger sample size, encompassing all factors that may affect thyroid structure and functions, are essential.","PeriodicalId":42868,"journal":{"name":"Turkish Journal of Endocrinology and Metabolism","volume":"1 1","pages":"270-276"},"PeriodicalIF":0.2,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89801877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the etiology of LH cannot be clarified, it may be due to the lipogenic effect of insulin or recurrent tissue trauma caused by injections. In this respect, we aimed to evaluate the relationship between vitamin D level and LH. Material and Methods: Patients with Type 2 diabetes mellitus aged 18 years or older, who were under insulin and/or exenatide treatment for at least one year were included in this study. The injection sites of the patients were examined by inspection and palpation method. Patients were categorized into two groups according to vitamin D levels as below and above 20 ng/mL. Results: A total of 140 patients, including 91 women and 49 men, aged between 20-78 years with a mean age of 54.53±13.89 were included in the study. LH was detected in 91 (65%) of 140 patients. This study demonstrated that there was a significant relationship between gender and LH. Statistically, the frequency of LH was higher in female patients (p=0.001). Further, a relationship between vitamin D levels and LH was also observed (p=0.006). Conclusion: Besides calcium metabolism, the effects of vitamin D on lipogenesis are also known. Vitamin D inhibits the differentiation of pre-adipocytes to mature adipocytes. This is the first study showing the relationship between vitamin D and LH in our knowledge.","PeriodicalId":42868,"journal":{"name":"Turkish Journal of Endocrinology and Metabolism","volume":"4 1","pages":"184-188"},"PeriodicalIF":0.2,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74095721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and Methods: Eighty (40 PCOS cases and 40 healthy controls) individuals were included. Whole blood and serum samples were taken from all participants. Enzyme linked immunosorbent (ELISA) was performed for measuring the levels of serum resistin. Whole blood was used for extracting total genomic DNA by the phenol-chloroform method. Polymerase chain reaction with fragment length polymorphism was performed for detecting single nucleotide polymorphism (SNP) in the promoter region (-420 C>G) of the resistin (RETN) gene by amplifying the oligonucleotide sequence of the SNP. The amplified products were first confirmed on 2.0% agarose gel for product size, and then restriction digestion of these products was performed by using the Bpil restriction enzyme. After completion of digestion, the products were resolved on 2.5% agarose gel with a 100 bp DNA ladder, and the bands were inspected to infer genotype. Data analysis was done using SPSS software and the association between serum resistin levels and RETN genotypes was analyzed. Results: There was no significant difference (p=0.125) observed in serum resistin levels between PCOS cases (mean±SD=19.33±3.50) and healthy controls (mean±SD= 13.48±1.31). The frequency of the G allele was high in PCOS cases (65%) than in controls (53.7%). The GG genotype frequency of SNP (-420 C>G) was high in PCOS cases (40%) than in controls (20%), but no association was found (p=0.148). The high serum resistin levels were significantly associated with the GG genotype in PCOS cases (p=0.027). Conclusion: High serum resistin levels are not associated with the genotypes of RETN (-420 C>G) polymorphism in PCOS women and controls, although women with PCOS had high GG genotype levels of serum resistin.
