Thyroid cancer in ovarian teratoma is reported to be rare and experiences are limited. A 26-year-old woman had undergone bilateral cystectomy and omentectomy for bilateral cystic adnexial masses. Pathological examination showed 1.5 cm follicular variant papillary thyroid carcinoma on the basis of unilateral mature cystic teratoma. Increased CA-125 and CA19-9 levels decreased to normal reference ranges after surgery, but postoperative magnetic resonance imaging indicated multiple abdominal cystic loci. After total thyroidectomy, high dose I-131 was administered to ablate thyroid tissue. Thereafter, levothyroxine was started to achieve subclinical hyperthyroidism. No iodine uptake was detected in post-therapeutic whole body scan (WBS) other than thyroid bed. This finding supported that tumor did not show dissemination to abdomen. No uptake on the first-year evaluation with low-dose I-131 WBS suggested the complete ablation of the thyroid gland. It is recommended that thyroid carcinoma arising from ectopic thyroid tissue in a teratoma should be managed as thyroid carcinoma in thyroid. However, direct dissemination to contiguous regions in abdomen and hematogenous dissemination to distant organs should be in mind. Radical surgery including total abdominal hysterectomy, bilateral salphingo-oopherectomy, pelvic and paraaortic lymph node excision and thyroidectomy is recommended. Fertility preserving surgery may be the surgical procedure as in the present case.

To investigate short-term effects of thyroidectomy-induced hypothyroidism on leptin, adiponectin, and resistin concentrations in association with anthropometric data.Thirty premenopausal women with euthyroid nodular goiter-mean age, 44.0 ± 11.6 years; mean body mass index (BMI), 28.6 ± 5.9 kg/m2; 13 obese, 7 overweight, and 10 normal weight subjects-scheduled for total thyroidectomy were included in the study. Serum leptin, adiponectin, resistin, free triiodothyronine, free thyroxine, thyroid-stimulating hormone, glucose, insulin, and C-reactive protein concentrations, lipid profile, and anthropometric variables were determined in the euthyroid state (preoperatively) and the hypothyroid state (postoperatively, with a thyroid-stimulating hormone concentration30 mIU/L).Body weight, BMI, waist and hip circumferences, body fat mass, and serum lipid concentrations increased significantly after thyroidectomy. No significant difference was found between preoperative and postoperative serum leptin, adiponectin, and resistin concentrations. Fat tissue mass-corrected leptin, adiponectin, and resistin concentrations did not differ significantly between euthyroid and hypothyroid periods. Thyroid hormone concentrations showed no significant correlations with adipokine levels.Serum adipokine concentrations seem not to change significantly during short-term thyroidectomy-induced hypothyroidism despite significant increases in body weight, BMI, fat mass, and lipid concentrations.

Mean platelet volume (MPV) was studied in subclinical hypothyroidism (SH) and the results are conflicting. The aim of this study is to assess how MPV is affected in overt hypothyroidism (OH) and mild SH, the 2 end points of hypothyroidism, in patients having low cardiac risk. Premenopausal women without any cardiac risk, 18 with OH, 30 with mild SH, and 37 euthyroid controls were enrolled. Overt hypothyroidism group had higher low-density lipoprotein cholesterol (LDL-C) and total cholesterol levels than the control group ( P < .001 and P < .05, respectively). Increase in MPV was insignificant in OH group when compared with SH and control groups. No correlation was observed between MPV and metabolic and hormonal parameters. Both OH and SH did not influence MPV and high-sensitivity C-reactive protein (hs-CRP) in patients with low cardiovascular risk, but these findings need to be further evaluated in this patient group.

Introduction Myotonic dystrophy (MD) or Steinert's syndrome is a rare cause of chronic diarrhea and anal incontinence. In the presence of chronic diarrhea and fecal incontinence with muscle weakness, neuromuscular disorders such as myotonic dystrophy should be considered in the differential diagnosis. Case Presentation We present the case of a 45-year-old Turkish man with Steinert's syndrome, who was not diagnosed until the age of 45. Conclusions In clinical practice, the persistence of diarrhea and fecal incontinence with muscle weakness should suggest that the physician perform an anal manometric study and electromyography. Neuromuscular disorders such as myotonic dystrophy should be considered in the differential diagnosis.

ObjectiveFibroblast growth factor 23 (FGF23), a phosphatonin, inhibits renal phosphate reabsorption and suppresses 1-α hydroxylase activity. Calcitriol stimulates FGF23 synthesis in bone. We aimed to determine the effect of vitamin D replacement therapy on serum FGF23 concentrations in vitamin D-deficient women and to compare the FGF23 concentrations of vitamin D-deficient patients with healthy subjects and patients with genetically determined hypophosphatemic rachitis.Design and methodsThe study group was composed of vitamin D-deficient females (n=18, mean age 29.1±9.9 years), vitamin D-sufficient healthy females (control group;n=19, mean age 28.5±5.2 years), and patients with genetically determined hypophosphatemic rachitis (n=13, mean age 26.5±15.1 years). The groups were compared for serum FGF23, 1,25-dihydroxyvitamin D3 (1,25(OH)2D), calcium, phosphate, bone turnover markers, intact parathyroid hormone (PTH), and urinary excretion of calcium and phosphate. The vitamin D-deficient group was re-evaluated after a standard treatment regimen.ResultsSerum FGF23 concentrations were significantly lower in vitamin D-deficient patients than in vitamin D-sufficient women and hypophosphatemic rachitis group. Serum FGF23 and phosphate concentrations further decreased significantly during replacement of vitamin D (Pr=−0.469,PConclusionDecreased FGF23 concentrations, which further decline during vitamin D replacement therapy, may have favorable action on bone mineralization by counterregulatory effect on phosphate homeostasis. Lower 1,25(OH)2D concentrations at baseline and hypophosphatemia during treatment may have dominating effects on FGF23 concentrations in vitamin D deficiency, leading to decreased FGF23 concentrations at baseline and during replacement therapy.

Summary Context Data regarding serum adipocytokine and ghrelin concentrations in different stages of anorexia nervosa (AN) is conflicting. Objective Our aim is to determine serum concentrations of adiponectin (ApN), leptin and ghrelin in different stages of AN and to evaluate their relationships with study parameters. Design setting and participants Study group was composed of four subgroups: Group 1: patients with a recent diagnosis of AN (n = 19); group 2: weight recovered (10% increase in body weight compared with baseline) subgroup of group 1 during follow-up (n = 10); group 3: recovered patients with a previous history of AN but normal menstrual cycles and body weight currently (n = 10); group 4: control group (n = 10). Venous blood was obtained for measurements of biochemical/hormonal parameters, ApN, leptin and ghrelin. Body composition was determined by bioimpedance analysis. Main outcome measures Changes in adipocytokine and ghrelin concentrations and relationships with anthropometric/biochemical parameters. Results Leptin : fat mass (kg) ratio was significantly higher in group 1 patients compared with group 4 (4·3 ± 4·6 vs. 1·1 ± 0·5 µg/l kg, P

Objectives: Recent research has shown that hypovitaminosis D may increase the risk of hypertension, vascular disease, diabetes mellitus, obesity and Metabolic Syndrome (MetS). Endothelial Dysfunction (ED) is one of the key components of MetS which is associated with an imbalance between vasoactive substances such as Nitric Oxide (NO) and Endothelins (ET). In this study, we assessed the association of 25(OH) D3 level with endothelial dysfunction and subclinical atherosclerosis in MetS patients. Design and Methods: 105 MetS patients and 48 controls were included. 25(OH) D3 levels were measured using Ultra-High Performance Liquid Chromatography (UHPLC). NOx (NO 2 plus NO 3 ) and Endothelin- 1(ET-1) concentrations were determined along with routine biochemical tests. Flow-Mediated Dilatation (FMD) and carotid Intima-Media Thickness (cIMT) were measured by ultrasonography. Results: In MetS patients, vitamin D and NOx levels were significantly lower (p

Objective: To describe and discuss potential relationships between anorexia nervosa (AN) and Raynaud's phenomenon, the course and concurrent treatment of these two disorders as they appeared simultaneously, and a potential treatment modification entailed in such concurrent therapies. Background: Although Raynaud's phenomenon has been described during the course of AN, the associations and interactions between these two conditions are not clear. Method: We report the medical workup, treatment, and outcomes in a 19-year old female patient who developed Raynaud's phenomenon following the onset of AN. Results: After treatment with nutritional rehabilitation, counseling, and individual and group therapy, the patient's weight, eating disorder-related behaviors, and attitudes improved significantly. Raynaud's related symptoms improved, following treatment with a calcium channel blocker and antiaggregant therapy. In conjunction with nutritional efforts to treat the patient's long-standing amenorrhea and osteopenia, the treatment team elected to also administer estrogen hormone in addition to oral calcium and vitamin D supplementation. Since oral contraceptives are to be avoided in patients with Raynaud's phenomenon who show clinical findings suggesting connective tissue disorder, the treatment team elected to treat this patient with transdermal hormone replacement therapy. Conclusion: The co-occurrence of AN and Raynaud's phenomenon merits close and persistent follow-up by a multidisciplinary team and may lead to alterations of usual therapeutic approaches. © 2007 by Wiley Periodicals, Inc.

Objectives Obesity and hyperinsulinemia connected with insulin resistance are the most important factors to manage a diabetic patient. We aimed to investigate the differences in demographic characteristics, insulin, C-peptide, HOMA-IR and CRP levels and lipid abnormalities between diabetic and non-diabetic obese patients. Design & Methods This study was carried out in the outpatient clinic of Internal Medicine. Diabetics ( n = 19) and non-diabetics ( n = 81), 10 men and 90 women, participated in the study. Age, duration of obesity and body mass index (BMI) and other anthropomorphic data were collected. Venous blood samples were taken, after 12 h of fasting to determine fasting blood glucose (FBG), insulin, C-peptide, total cholesterol (TC), HDL cholesterol (HDL-C), triglyceride (TG) and C-reactive protein (CRP) concentrations. LDL cholesterol (LDL-C) was estimated by using Friedewald formula. Homeostasis model of insulin resistance (HOMA-IR) was calculated as [fasting insulin (μU/mL) × fasting glucose (mmol/L)/22.5]. Results Diabetics had longer duration of obesity ( p p p p p p p p > 0.05) and insulin and C-peptide levels were higher in diabetics without statistical significance ( p > 0.05) as shown in the table below. Two group comparisons were performed with Mann–Whitney U test, using SPSS for windows 12.0. Conclusion Although insulin and C-peptide levels were higher in diabetics without being statistically meaningful, HOMA-IR, as a golden test, was significantly high in diabetics. Obesity is the principal disorder in pathophysiology of diabetes and must be treated rigorously. But it should always be kept in mind that treatment of obesity is frustrating and frequently discouraging. Obese people should be followed up with HOMA-IR.
