RESUMEN

CONTEXT: Exenatide is a Glucagon-like Peptide-1 receptor agonist, which is widely used for type 2 diabetes mellitus (T2DM). Limited and conflicting results are present about the effect of exenatide on the thyroid gland. OBJECTIVE: The aim of this study was to evaluate the effect of exenatide treatment on structural and functional features of the thyroid gland in patients with T2DM. DESIGN: The study was a prospective study, performed between 2015 and 2017. The laboratory values and thyroid ultrasonography features were compared before and after exenatide treatment. SUBJECTS AND METHODS: The study included 39 obese diabetic patients. After inclusion to the study exenatide was started and patients were followed up for 6 months. Total thyroid volume, thyroid function tests, serum carcinoembryonic antigen (CEA) and calcitonin levels, the size and appearance of thyroid nodules were compared between baseline and after 6 months of treatment. RESULTS: Exenatide at a dose of 5µg bid was started, increased to 10 µg bid after 4 weeks. We found a statistically significant decrease in thyroid volume (p=0.043) and serum thyroid stimulating hormone (TSH) levels (p=0.007), whereas serum ATPO. ATGl, fT4, fT3, CEA and calcitonin levels did no change with 6 months of exenatide treatment. There were no significant differences in the size and appearance of the thyroid nodules with treatment. The thyroid volume decrease was not correlated with TSH, body mass index and HbA1c reduction. CONCLUSION: Exenatide treatment for 6 months decreased serum TSH levels and thyroid volume, but had no effect on thyroid nodules and serum CEA and calcitonin levels.

RESUMEN

AIMS: The aim of this study was to evaluate the relationship between pathological findings and clinical features in patients with ovarian mature cystic teratomas (MCTs). MATERIALS AND METHODS: We reviewed and compared the demographic and clinical features of 32 patients confirmed pathologically as having MCT at a university hospital from 2009 to 2014, with MCT contents such as skin, hair, sebum, and cartilage. RESULTS: The mean age of the patients was 33.7 ± 13.4 years. The mean tumor diameter was 7.1 ± 3.3 cm (range: 2-15 cm). The mean serum CA-19.9 level was 37.5 ± 79.5 IU/ml and the mean serum CA-125 level was 29.1 ± 33.0 IU/ml. The postmenopausal and pregnancy status rates of participants were 18.8, and 15.6%, respectively. The mean age, postmenopausal and pregnancy status, tumor size, symptoms related to MCT and laterality of the tumor did not differ among the patients according to the MCT contents. CONCLUSIONS: Our findings suggest no relationship between the clinical features and histopathological contents of MCTs.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the adverse effects of diabetes mellitus on the knee joint by using ultrasonography. PATIENTS AND METHODS: One hundred and two subjects with diabetes for 5 years and more were compared prospectively with 93 age and sex-matched healthy subjects. Individuals in both groups were aged between 40-55, had a body mass index below 30 kg/m2, and had no knee joint complaints. Femoral cartilage thickness, cartilage surface, quadriceps and patellar tendon thickness in both knees were assessed by ultrasonography using a 5-12 mHz linear transducer. RESULTS: According to ultrasonographic findings, thin and irregular femoral cartilage was more common in diabetic patients than in healthy controls (p<0.05). Diabetic patients had thinner quadriceps tendons compared to the control group (p<0.001). No statistically significant difference was recorded in patellar tendon thickness (right knee p=0.697, left knee p=0.639). The presence of effusion in the suprapatellar recess of the right knee was more common in diabetics than non-diabetics (p=0.006). CONCLUSIONS: Irregularity and thinning of the distal femoral cartilage in diabetics may indicate cartilage degeneration. In addition, the decrease in the thickness of the quadriceps tendon may lead to instability and adversely affect the knee joint. These sonographic findings may indicate early knee joint degeneration, so ultrasonography may help determine the possible risk of osteoarthritis in diabetic patients.

RESUMEN

BACKGROUND: Effects of rosiglitazone in the prevention of adhesion formation were evaluated. METHODS: Eighty Wistar albino rats were randomly grouped into eight equally sized groups. A 2-cm segment of the antimesenteric surface of the right uterine horn was traumatized to form a standardized lesion, using bipolar cautery. A dose-response study was performed with 0.1, 0.3, 1 and 3 mg/kg/day rosiglitazone. Fifteen days later, adhesions were evaluated clinically and histopathologically. A time-response study was performed with 1 mg/kg/day rosiglitazone (the minimum dose found to significantly affect adhesion formation). Rosiglitazone was given for 7 days post-operatively and results were compared with those of control and the 15-day group (time-response). In all these studies, rosiglitazone was orally administered 3 days before the operation and continued post-operatively. In two further experimental groups, rosiglitazone was only administered pre-operatively or post-operatively. RESULTS: Approximately 1 mg/kg/day rosiglitazone was found to reduce adhesion scores both clinically and histopathologically. Duration of treatment was also found to affect the extent of adhesion formation. However, giving rosiglitazone either just pre-operatively or post-operatively did not significantly reduce adhesion formation. CONCLUSION: Rosiglitazone with peroxisome proliferator-activated receptor (PPAR)-gamma agonist activity reduced the formation of i.p. adhesion possibly by reducing the initial inflammatory response and the subsequent exudation in this study.
