RESUMO
OBJECTIVE: Lymph node metastasis is frequently detected in differentiated thyroid cancers. Central dissection is performed to the lymph nodes in patients with microscopic metastases in the intraoperative evaluation. Other indications for central dissections are tumor size and cervical lateral lymph node metastasis. We consider that the localization of thyroid cancer in the thyroid lodge may be another risk factor for central lymph node metastasis. For this reason, the purpose of the present study was to investigate the relations between thyroid cancer localization and lymph node metastasis in differentiated thyroid cancer patients who had no preoperative cervical metastases and who underwent total thyroidectomy, and peritracheal, perithyroidal, and central lymph node dissection. METHOD: A total of 213 differentiated thyroid cancer cases followed in our general surgery and endocrinology clinic between September 2016 and May 2020 were evaluated retrospectively. Based on the data in the files, the patients who underwent total thyroidectomy, and central, perithyroidal, and peritracheal lymph node dissection were included in the study. The patients were divided into four Groups according to tumor localizations, those with tumors adjacent to the trachea (Group 1), upper thyroid pole (Group 2), thyroid middle part (Group 3), thyroid inferior (Group 4). The demographic characteristics, laboratory parameters, cancer types, and lymph node metastasis rates of the Groups were evaluated. RESULTS: A total of 84% (179) of the cases had thyroid papillary cancer, 11.73% (25) had thyroid follicular cancer, and 4.2% (9) had poorly differentiated thyroid cancer. The mean age of all patients was found to be 49 ± 8.3 years, and the female/male ratio was 2.4. It was found that the differentiated thyroid cancers metastasized to the perithyroidal, peritracheal, and central lymph nodes at a rate of 57.74%. The distribution of these metastases according to the Groups was; 62.85% in Group 1, 11.53% in Group 2, 43.9% in Group 3, and 88.57% in Group 4. It was also found that 80.32% of the papillary cancer cases and 57.14% of the follicular cancer cases metastasized to central (level VI) lymph nodes in Group 4. CONCLUSION: The localization of differentiated thyroid cancers is a new risk factor for perithyroidal metastases.

AIM: Sodium-glucose cotransporter 2 inhibitors have been shown to reduce the risk of cardiovascular disease in type 2 diabetes (T2DM) patients. The purpose of this study was to evaluate cardiovascular disease risk indirectly through Doppler ultrasonography (USG) of carotid artery vascular markers in T2DM patients using dapagliflozin. METHODS: One hundred forty-five patients presenting to our clinic between March 2016 and June 2018 and diagnosed with T2DM were included in the study. These were divided into two groups - a dapagliflozin group of 85 patients and a 60-member non-dapagliflozin control group. Common carotid artery end-diastolic velocity (EDV), peak systolic velocity (PSV), and resistive index (RI) parameters were evaluated using Doppler USG in both groups. RESULTS: The mean duration of follow-up was 2.2 ± 0.4 years. Mean ages were 45 ± 14 years in the dapagliflozin group and 42 ± 15 in the control group. Mean HbA1c was 7.4 ± 1.6 in the dapagliflozin group and 7.3 ± 2.1 in the control group. Common carotid artery, PSV, and EDV parameters were higher (p = .012/p = .036), while RI was lower (p Ë .001), in the dapagliflozin group than in the control group. CONCLUSION: Vascular resistance was lower in the group using dapagliflozin for diabetes management.

OBJECTIVE: To investigate the effects of haemodynamic indices on colour Doppler ultrasound in differential diagnosis in patients with postpartum thyroiditis and with Graves' disease. METHODS: The cross-sectional study was conducted at the Endocrinology Polyclinic of Medical Park Hospital, Ordu, Turkey, from March 2017 to May 2018 and comprised patients referred from the Gynaecology Department for routine check-up after parturition within the first 6 months. The patients were divided into two groups. Group 1 had postpartum thyroiditis patients and Group 2 had those of Graves' disease. In both groups, parameters measured were peak systolic velocity, end-diastolic velocity and resistive index of the inferior thyroid artery with proper angle (45-60°) on colour Doppler ultrasound. Data was analysed using SPSS 20. RESULTS: Of the 42 subjects,18(42.85%) were in Group 1 and 24(57.14%) were in Group 2. Peak systolic velocity and end-diastolic velocity values of the inferior thyroid artery were higher in Group 2 compared to Group 1 (p<005). (p<0.05), while the resistive index value was significantly higher in Group 1 compared to Group 2. CONCLUSIONS: Due to its wide availability, the use of colour Doppler ultrasound parameters indicating parenchymal perfusion were found to be broadly useful in distinguishing between postpartum thyroiditis and Graves' disease.

BACKGROUND: In this study, we aimed to retrospectively evaluate treatment outcomes and treatment methods in acromegaly patients. MATERIALS AND METHODS: The study included 65 acromegaly patients followed in Sakarya University Faculty of Medicine Department of Endocrinology in Turkey between 2004 and 2013. Clinical, biochemical, and radiological data were obtained retrospectively from the medical files of the patients. All cases have been discussed in the endocrinology and pituitary surgery council, and a multidisciplinary treatment approach had been chosen in management. RESULTS: Sixty-five patients were included in the study. Of the patients, 57% were female. Mean age was 45.3 ± 9.2 years old. Of the cases, 12.3% were microadenomas (n = 8, tumor diameter <10 mm) and 87.6% were macroadenomas (n = 57, tumor diameter ≥10 mm). In our study, 70% remission was achieved with the first operation and medical treatment. Patients with invasive acromegaly without remission after the first operation underwent reoperation, medical treatment, and conventional or stereotactic radiotherapy and achieved 45% remission rate. CONCLUSION: Pituitary surgery is the first treatment option for acromegaly. In patients who could not be remissioned after the first operation, remission can be achieved by combined therapy consist of reoperation, medical treatment, and conventional or stereotactic radiotherapy.
RESUMO
BACKGROUND: Osteoporosis affects quality of life (QoL) and may lead to depression in women. The purpose of this study was to evaluate the effects of zoledronic acid (ZA) treatment on depression and QoL in women with postmenopausal osteoporosis (PO). MATERIALS AND METHODS: A total of 88 newly diagnosed women with PO were included in this study. All patients were treated with once-yearly ZA (5 mg). A QoL questionnaire from the European Foundation for Osteoporosis and Beck Depression Inventory were given to patients at baseline and at 12 months. The results for baseline and post - 12th month were compared, and bone mineral density (BMD) levels were compared. RESULTS: The consumption of once-yearly ZA (5 mg) treatment increases BMD at levels of lumbers 1-4 (P = 0.026), total Hip T score's P value is same as femoral neck (P: 0,033). ZA 5 mg treatment also improved QoL (P = 0.001) and reduced depression (P = 0.001). CONCLUSION: ZA treatment increases BMD levels and QoL while reducing depression. Once-yearly ZA (5 mg) may be considered for postmenopausal women as a first-line treatment.
RESUMO
OBJECTIVES: Pituitary diseases may cause psychiatric and personality alterations. We aimed to compare the personality traits of acromegalic patients with those of patients with non-functioning pituitary adenomas and a healthy control group. DESIGN: Fifty-eight acromegalic patients, 45 patients with non-functioning adenoma, and 40 healthy subjects were enrolled in the study. Cloninger's Temperament and Character Inventory (TCI), Beck Depression Inventory, Beck Anxiety Inventory, and Rosenberg Self-Esteem Scale (RSES) were used to assess personality, depression, anxiety, and self-esteem. RESULTS: Depression score was higher in acromegaly and non-functioning adenoma groups than healthy controls. RSES scores were similar among the three groups. Regarding the scales of TCI, only novelty-seeking was significantly reduced in acromegaly and non-functioning adenoma than the control group. Pairwise comparisons revealed that the difference was due to the difference between acromegalic patients and controls. Scales of TCI were correlated with depression and anxiety in patients with acromegaly and non-functioning adenoma but not in healthy controls. CONCLUSION: This study showed that novelty-seeking was reduced in patients with acromegaly. Both the hormonal lack and excess and structural changes can lead to cognitive and personality changes in acromegaly. More studies are needed to be carried out about personality characteristics in pituitary diseases.

PURPOSE: The purpose of the present study was to determine the types and prevalence of cancers in obese patients who have risks for cancer with multidisciplinary evaluation in managing the patients before bariatric surgery. MATERIALS AND METHODS: The study had a descriptive cross-sectional method conducted by examining patients' files retrospectively. The frequency and types of diseases with cancer during the multidisciplinary evaluation of the study group with a BMI ≥ 40 kg/m2 before bariatric surgery were used as the study data. RESULTS: A total of 1354 (64.97%) of these patients underwent bariatric surgery (for obesity), and 730 (35.02%) cases underwent metabolic surgery (type 2 diabetic patients). Eighteen patients had thyroid papillary cancer (0.86%) and colon cancer was detected in 8 people (0.38%), breast cancer in 6 people (0.47%), stomach cancer in 5 people (0.23%), kidney cancer in 3 people (0.1%) 4), lung cancer in 2 people (0.09%), pancreatic cancer in 2 people (0.09%), adrenal cancer in 2 people (0.09%), and neuroendocrine tumor in 1 person (0.04%). CONCLUSION: It was found that obesity and some cancers are related. Weight loss to be achieved with obesity surgery can reduce the risk of obesity-related cancers.

BACKGROUND: Vitamin D deficiency is frequently seen in patients with polycystic ovary syndrome (PCOS) and has been shown to exhibit multiple effects on the disease process. The purpose of this study was to investigate the role of vitamin D deficiency in complex PCOS pathophysiological pathways. METHODS: Two hundred sixty-seven patients with PCOS were divided into two groups Group 1 with 25(OH)D3 deficiency, and Group 2 with normal 25(OH)D3. Biochemical and hormonal parameters (androgen hormones, gonadotropins, and thyroid function tests) were compared between the two groups. RESULTS: Eighty-six percent of the patients (n=231) were in Group 1 and 14% (n=36) in Group 2. Statistically significantly higher concentrations of serum testosterone, dehydroepiandrosterone-sulfate and LH were determined in Group 1 (p<0.05). 25(OH)D3 concentrations were negatively correlated with body mass index (r=-0.459), serum testosterone (r =-0.374) and dehydroepiandrosterone-sulfate levels (r=-0.418); (all; p< 0.05). CONCLUSION: The study findings show that low 25(OH)D3 levels are associated with high androgen levels in women with PCOS. Vitamin D deficiency should be considered as an additional risk factor in the development of PCOS. We think that providing vitamin D supplementation for women from identified deficiency areas can reduce the risk of PCOS development.

BACKGROUND: The aim of this study was to determine changes in thyroid hormones and morphology with weight loss after bariatric surgery in obese patients. METHODS: This prospective study was performed in our endocrinology and surgery clinic. Pre- and post-bariatric surgery thyroid function tests and thyroid ultrasonography parameters were compared. RESULTS: Four hundred seventy-two patients were included in the study. Mean weight loss after surgery was 30.7 ± 5.1 kg. TSH levels decreased statistically significantly parallel with weight loss and decreased BMI (p = 0.025) after bariatric surgery. However, no statistically significant change was observed in fT4 or fT3 levels (p > 0.05). A significant increase in thyroid parenchyma echogenicity, correlated with weight loss and time elapsed since surgery, was detected at ultrasonography (US) grayscale histogram analysis compared with muscle echogenicity (p = 0.032). An increase in echogenicity was even detected in patients with isoechoic thyroid parenchyma before surgery. Fasting insulin and HOMA-IR levels decreased after surgery (p = 0.010 and p = 0.001, respectively). Patients were divided into three groups based on weight loss. In group 3, preoperative TSH of 4.1 ± 0.7 decreased to 1.6 ± 0.7 postoperatively (p = 0.001), while preoperative HOMA-IR of 4.9 ± 1.9 decreased to 2.4 ± 0.8 postoperatively (p = 0.001). CONCLUSIONS: Obesity causes thyroid hormone resistance through a mechanism similar to insulin resistance and leads to an increase in TSH similar to hyperinsulinemia. Our findings show that echogenicity at thyroid US increases in line with weight loss following bariatric surgery.

BACKGROUND AND AIMS: A national lockdown to prevent the spread of coronavirus disease (COVID-19) in Turkey was introduced in March 2020. We think that lockdowns may lead to weight gain and worsening of glycemic parameters in patients with type 2 diabetes mellitus (DM). The purpose of this study was to investigate how type 2 DM patients were affected by the lockdown. METHOD: Type 2 DM patients unable to attend regular follow-ups due to lockdown over a 75-day period between March and June 2020 and who again attended polyclinic follow-up when the lockdown was lifted were included in the study. These patients' glycemic control and weight status were compared with the pre-lockdown period. In addition, patients' general habits, and adherence to diet and exercise were evaluated, while their general health was assessed using the Short-Form 36-item survey. RESULT: The research involved 101 type 2 DM patients, 57 men (56.5%) and 44 women (44.5%), with a mean age of 55 ± 13. Patients' mean pre-lockdown weight was 84.7 ± 16.4 kg, rising to 85.5 ± 16.8 kg post-lockdown, although the increase was not statistically significant (p = 0.781). In terms of glycemic parameters, Hba1c rose from 7.67 ± 1.76 to 8.11 ± 2.48, and fasting glucose from 157.9 (83-645) mg/dl to 163.2 (84-550) mg/dl, none of which were statistically significant (p = 0.253, p = 0.079, respectively). CONCLUSION: In addition to weight gain among type 2 DM patients during the Covid 19 lockdown, statistically insignificant increases were also observed in such glycemic parameters. This was a small sample and further studies with larger sample are needed.

CONTEXT: In patients with coexisting iron-deficiency anemia and subclinical hypothyroidism, anemia does not adequately respond to oral iron therapy. OBJECTIVE: We studied whether iron-deficiency anemia might indicate treatment of subclinical hypothyroidism. DESIGN: PATIENTS were assigned to a control or experimental group: 240 mg/d oral iron alone (iron group) or 240 mg/d oral iron plus 75 microg/d levothyroxine (iron/levothyroxine group). Levels of hemoglobin, hematocrit, red blood cell count, serum iron levels, ferritin, total iron-binding capacity, TSH, and free T(4) were measured before and after treatment. SETTING: The study was conducted at a university hospital outpatient clinic. PATIENTS: Fifty-one patients with coexisting iron-deficiency anemia and subclinical hypothyroidism participated in the study. INTERVENTION: PATIENTS were treated as described above in either the iron group or the iron/levothyroxine group. MAIN OUTCOME MEASURE: A clinically satisfactory increase in hemoglobin was regarded as successful. RESULTS: Mean hemoglobin levels increased by 0.4 g/dl in the iron group [95% confidence interval (CI) 0.2-0.7, P = 0.001], whereas it increased by a mean of 1.9 g/dl in the iron/levothyroxine group (95% CI 1.5-2.3, P < 0.0001). The increase in serum iron was greater in the iron/levothyroxine group by a mean of 47.6 microg/dl (95% CI 34.5-60.6, P < 0.0001). Increases in hemoglobin, red blood cells, hematocrit, and serum ferritin levels after treatment were statistically significantly greater in the iron/levothyroxine group (P < 0.0001). Starting hemoglobin and increase in hemoglobin were negatively correlated in the iron/levothyroxine group (r = -0.531, P = 0.006). CONCLUSIONS: Subclinical hypothyroidism should be treated in iron-deficiency anemia patients when both conditions coexist. This would provide a desired therapeutic response to oral iron replacement and prevent ineffective iron therapy.

PURPOSE: Propylthiouracil is one of the thionamides used in the treatment of Graves' disease. The drug has serious side effects and long-term treatment might be needed to achieve remission. We designed this study to evaluate the clinical and thyroid Doppler characteristics that might predict time to remission and treatment failure in propylthiouracil treated Graves' patients. METHODS: 26 patients, among 134 presenting to our university hospital outpatient clinic between Feb -July 2007 and with first time diagnosis of clinical thyroid dysfunction, were clinically and ultasonographically diagnosed with Graves' disease. Doppler parameters, serum thyrotropin, free thyroxine and free triiodothyronine were measured at the beginning of the study and thyroid studies were repeated every 4 weeks until remission. Propylthiouracil 300 mg/day was started for each patient at the time of diagnosis and doses were titrated according to repeat thyroid studies. Patients were treated and followed up for 18 months. RESULTS: Treatment failure was associated with smoking (P = 0.001) and male gender (P= 0.037). Stepwise multiple regression analysis revealed that age, free thyroxine and superior thyroid artery flow rate were predictors of time to remission (P= 0.001, 0.002 and 0.003, respectively). CONCLUSION: The time to remission in Graves patients treated with propylthiouracil can be predicted using age, serum free thyroxine and superior thyroid artery flow rate. This may help early consideration of alternative treatment for the patients requiring prolonged treatment for remission or for those who fail medical treatment. This would decrease unnecessary, long-term propylthiouracil exposure with its serious side effects.

OBJECTIVE: The purpose of providing and maintaining a proper metabolic control is to prevent the development of chronic complications. In this study, we aimed to determine the influence of flexible insulin dosing with carbohydrate counting method on metabolic and clinical parameters in type 1 diabetes patients. MATERIAL AND METHODS: This study was conducted with patients following up at the Endocrinology Clinic with a diagnosis of type 1 diabetes mellitus between 2012 and 2015. Metabolic and clinical parameters before and after carbohydrate counting were compared. RESULTS: Forty patients were included in the study. Of the patients, 40% (n = 16) were female, and 60% (n = 24) were male, and mean age was 21.5 ± 7 year at the time of diagnosis. Statistically significant differences were not detected when haemoglobin A1c, fasting plasma glucose, post-prandial glucose, LDL-cholesterol, and HDL-cholesterol levels were compared at standard dose insulin use and after carbohydrate counting (P < 0.005). Among the parameters measured when the patients received standard dose of insulin without counting carbohydrate and flexible insulin dosing by counting carbohydrate, statistically, significant differences were not detected for baseline insulin dose, bolus insulin dose, triglyceride level, body mass index, or monthly hypoglycemia episodes (P > 0.05). CONCLUSION: Flexible insulin dosing with carbohydrate counting provides significant improvements in clinical and metabolic control. We detected improvements in lipid profiles and glycemic control. Additionally, patients generally did not gain weight despite flexible nutrition, and frequency of hypoglycemia remained unchanged despite strict glycemic control.
RESUMO
BACKGROUND: Elevated anti-Saccharomyces cerevisiae antibody (ASCA) immunoglobulin (IgG) and IgA levels were first described in the serum of Crohn disease patients and have increasingly been reported in other inflammatory diseases. The role of in situ and remote inflammation in atherosclerosis is a major area of interest. In this study, we compared ASCA IgG and IgA levels in acute myocardial infarction (AMI) and controls to investigate the possible role of ASCA in AMI. METHODS: Serum samples were obtained from 140 consecutive patients who presented to the emergency department with acute chest pain. AMI was diagnosed by electrocardiography and serial enzymes. Patients ruled out for acute coronary event were grouped as controls. ASCA IgA and IgG levels were determined using enzyme-linked immunosorbent assay. Groups were compared for statistically significant difference. RESULTS: ASCA IgG titers ranged between 0.1 and 31.0 RIU/mL (mean 4.92) in the AMI group and 0.1 and 6.0 (mean 0.84) in the controls. The groups were found to differ very significantly (p = .001). ASCA IgA titers ranged between 2.0 and 200.0 RIU/mL (mean 13.73) in the AMI group and 2.0 and 11.5 RIU/mL, (mean 4.25) in controls. The groups differed significantly (p = .32). AMI and controls were also analyzed for ASCA IgA and IgG positivity. Both groups differed significantly from controls (p = .013). CONCLUSION: Elevated ASCA IgA and IgG levels as well as ASCA positivity in the AMI might suggest use of ASCA as a marker for atherosclerotic plaque instability. It might also provide a link between inflammatory processes and increased cardiovascular risk. Further studies are needed on a Saccharomyces cerevisiae-based diet, related intestinal colonization, and associated inflammation, autoimmune disorders, and cardiovascular events.

OBJECTIVE: Diabetes mellitus and obesity are well-known risk factors associated with obstructive sleep apnea (OSA). Cushing's syndrome (CS) is also characterized by obesity and diabetes mellitus. However, the association between CS and OSA remains unclear. Therefore, we investigated the possible associations between CS and OSA in this study. PATIENTS AND METHODS: Thirty female patients with newly diagnosed active CS and 30 age-, gender- and body mass index (BMI)-matched controls were included in this study. All participants were evaluated by overnight polysomnography. OSA was defined as having an apnea-hypopnea index (AHI) score of ≥5 events/h. Insulin resistance was calculated by homeostasis model assessment (HOMA) scores. Fasting serum cortisol was also determined. RESULTS: The prevalence of OSA was higher (50% vs 23%, P = 0.003) in patients with CS compared with the control subjects. The mean HOMA (P = 0.046) and AHI (P = 0.028) scores were higher in patients with CS compared with the control subjects. AHI was positively correlated with the HOMA scores (r = 0.281, P = 0.046) in both groups. Linear regression analysis showed that serum cortisol remained as an independent predictor for AHI after controlling for BMI and HOMA score (P < 0.001). CONCLUSIONS: The prevalence of OSA increased in patients with CS compared with control subjects with similar ages and BMI levels. Hypercortisolemia is an independent risk factor for developing OSA. The presence of OSA needs to be considered in patients with CS.

Osteoporosis and periodontal disease are linked by an altered receptor activator of nuclear factor κB ligand and osteoprotegerin ratio (RANKL/OPG), and medical treatment with bisphosphonate (BP) may help control these molecules. The effect of BP on clinical findings and gingival crevicular fluid (GCF) values of RANKL and OPG using enzyme-linked immunosorbent assays was evaluated in postmenopausal women; 13 patients with both chronic periodontitis and osteoporosis (group A), 12 systemically healthy patients with chronic periodontitis (group B), 12 periodontally healthy patients with osteoporosis (group C), and 10 systemically and periodontally healthy individuals (group D). Recordings were repeated at the end of months 1, 6, and 12 in groups A, B, and C. At the baseline, groups A and B exhibited the lowest OPG values (P < 0.05). After periodontal treatment, OPG values were markedly increased at the end of 6th month in group A and 12th month in group B (P < 0.008). There was no significant difference in GCF RANKL values among groups (P > 0.05) or during the observation period (P > 0.008). The use of BP may be effective in preventing periodontal breakdown by controlling the levels of these markers in osteoporosis as an adjunct to periodontal treatment.

BACKGROUND: Sufficient clinical data are not available on the effect of hypothyroidism on olfactory function in adults. In this study, we aimed to evaluate the olfactory function of adult patients diagnosed with primary hypothyroidism. METHODS: Forty-five patients aged between 18 and 60 years who were diagnosed with clinical primary hypothyroidism and 45 healthy controls who had normal thyroid function tests were included in the study. Sniffin' Sticks olfactory test results of the 2 groups were compared. The relationships between thyroid function tests and olfactory parameters were evaluated. RESULTS: Odor threshold, identification, and discrimination scores of the hypothyroid group were significantly lower than those of the control group (p < 0.001). A significant positive correlation was detected between free triiodothyronine (FT3) levels and odor threshold, identification, and discrimination scores (p < 0.001). There was no significant relationship between thyroid-stimulating hormone (TSH) or free thyroxine (FT4) levels and olfactory parameters. CONCLUSION: Our study revealed diminished olfactory function in adults with hypothyroidism. FT3 levels were found to have a more significant relationship with olfactory parameters than TSH or FT4 levels.

INTRODUCTION: One of the cardiovascular effects of hyperthyroidism is increased carotid intima media thickness (CIMT). The aim of this study is to investigate the CIMT in patients with Graves' hyperthyroidism and the effect of propylthiouracil (PTU) therapy on CIMT. METHOD: Twenty-six patients with Graves' hyperthyroidism and 33 healthy controls were included in the study. CIMT was measured at the right and left external carotid arteries in every patient in both groups. CIMT was measured before and after the PTU therapy in patients with Graves' hyperthyroidism. RESULTS: There was a significant difference in CIMT between the group of Graves' hyperthyroid patients and the control group (0.72 versus 0.55 mm, P < 0.0001) at baseline. Twenty-five of 26 patients with Graves' disease were followed up for 18 months prospectively. Euthyroidism has been achieved in 21 patients. After 18 months of treatment, CIMT decreased significantly compared with the baseline values [0.84 (0.54-1.3) to 0.72 (0.50-1.2), change 0.12 mm, P < 0.001]. CONCLUSION: Graves' hyperthyroidism is associated with atherosclerosis as assessed by CIMT. Treatment of Graves' hyperthyroidism with PTU decreases the CIMT.
