Abstract
Background: Fetal hyperinsulinemia correlated with large birth weight and impaired glucose tolerance test and obesity in second decades of life. In this study we compared the correlation between fetal insulin production (as estimated by amniotic fluid (AF) C-peptide concentration) and AF insulin with macrosomia (as estimated by neonatal birth weight 4000 gr).
Methods: Thirty eight neonates were studied. Ten infants were macrosom and 28 were normal (birth weight < 4000 gr). Amniontic fluid C-peptide and insulin concentration and mother and fetal blood C-peptide and insulin were measured during delivery with radioimmunoassay and mother and fetal glucose were measured at the same time and correlated with neonatal macrosomia within first hour of birth.
Results: There was a significant correlation between infant serum C-peptide level and macrosomia. Amniotic fluid insulin level was higher in the macrosom infants but this correlation was not significant. AF C-peptide was higher in the macrosom group. Also there was a significant correlation between maternal serum C-peptide and macrosomia. Infant and mother serum insulin was higher in the macrosom group.
Conclusion: Our results suggest that fetal insulin (as estimated by AF C- peptide) and mother insulin and C- peptide production, can influence fetal weight and induce fetal macrosomia.

Abstract
Background: Pump therapy (CSII) is offered as a safe and effective treatment for patients with type 1 Diabetes. We examined the efficacy and safety of continuous subcutaneous Insulin Infusion Therapy for six months as a before-after clinical trial study among type 1 diabetic patients. This is the first survey of this experience in Iranian patients.
Methods: We recruited, type 1 diabetic patients without chronic complications of diabetes (retinopathy, nephropathy and etc.) and followed them for six months as a before-after clinical study with use of the pump. The efficacy of this way was assessed with HbA1C and fasting blood sugar measurements. Safety was estimated by frequency of clinical hypoglycemia episodes.
Results: Our patients were 7 men and 2 women aged 15 - 39 years with past history of diabetes by ranging from 0.1 to 15 years. Mean level of HbA1C at the beginning of study and after six months follow-up were %8.6 and %7.1, respectively, with significant statistically difference between them (P= 0.02). During pump therapy the mean dose of insulin were decreased to 10 units with statistically significant difference to before investigation (P = 0.03). No case of hypoglycemia and weight loss was seen. One patient had 4 kg weight gain without any significant statistical effect.
Conclusion: It seems CSII Therapy in Iranian patients with type 1 Diabetes mellitus was effective and safe. We can not conclude about possible side effects of pump based on this study.

Abstract
Background: A unique subset of Individuals with normal body mass index (BMI= 18.5-24.9 kg/m2) and high body fat percentage (above 30% in women and 23% in men) that are termed as normal weight obese, are at increased risk for development of the metabolic syndrome and chronic diseases because the adipose mass and the excess of fat mass are an important source of proinflammatory cytokines. The aim of the present study was based on this hypothesis that women with high body fat percentage and normal body mass index are at increased risk for the metabolic syndrome in compared to healthy non obese women. Methods: This was as case-control study in which 40 obese women with normal weight (BMI= 18.5-24.9 kg/m2) and body fat percentage above 30% (FM> 30%) and 30 non-normal weight obese women (BMI= 18.5-24.9 kg/m2) and fat percentage less than 25% (FM <25%) who were matched for age (mean age = 28 years) recruited for this study. The components of metabolic syndrome including Anthropometric variables, blood pressure and fasting plasma concentrations of total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, glucose and insulin were measured. Results: The anthropometric measurements including waist and hip circumferences in NWO was higher than non-NWO (respectively 74.78±4.81 vs. 70.76±2.91 and 99.12±4.32 versus 93.16±2/91, Pvalue<0.001), while the waist-to-hip ratio did not differ between the two groups (p=0.448).Also no significant differences were observed in concentrations of total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, fasting plasma glucose, systolic and diastolic pressure between groups. Fasting serum insulin and insulin resistance was higher in NOW compared to non NWO (Pvalue<0.05) and insulin sensitivity in NWO was lower than non NWO (0.357 versus 0.374, pvalue = 0.043). Conclusion: Because of the higher serum insulin concentration and the lower insulin sensitivity, obese women with normal body mass index but high body fat percentage can be associated with a higher risk for metabolic dysregulation and metabolic syndrome compared to healthy women with the same body mass index and normal body fat percentage

Abstract
Background: The major cause of obesity is an imbalance between energy intake and energy expenditure and resting energy expenditure (REE) is the most important determining factor in metabolism because it can reduce obesity and body fat mass gain. Overt hypothyroidism is associated with a lower resting energy expenditure (REE). With treatment, the resting energy expenditure (REE) will be normal. But a group of patients with treatment and normal serum level of TSH and thyroid hormones, Continue to complain of the lack of improvement of Clinical signs of overt hypothyroidism. This study is designed whether patients that have Clinical signs of overt hypothyroidism in compared with patients without Clinical signs, resting metabolic rate, body composition and lipid profile are different or not.
Methods: This study is a descriptive and comparative study on 100 women with overt hypothyroidism are treated with levothyroxine. The patients were divided into 2 groups of 50 patients with and without clinical signs. All patients were matched for age and BMI and menstrual cycle. 2 groups regarding anthropometric measurements, resting energy expenditure (REE), body composition, thyroid hormones, lipid profile and diet were compared with each other.
Results: The average resting energy expenditure (REE) and adjusted of it for weight was significantly lower in the group with Clinical signs (Pvalue<0.03). But there was no significant difference between the 2 groups for the form of an adjustment for fat free mass (FMM) and FT3. The body fat mass (FM) was higher in the group with Clinical signs (Pvalue<0.005).But there was no significant difference between the 2 groups in the percentage of body fat mass and fat free mass (FMM). Serum levels of TSH, TF4, FT4, TT3, FT3, total cholesterol, HDL, LDL, there was no significant difference between the 2 groups. But the level of blood triglycerides (TG) in the group with Clinical signs was significantly higher than the group without Clinical signs (Pvalue<0.01).
Conclusion: Patients with Clinical signs, lower resting energy expenditure (REE) and fat mass (FM) and triglycerides blood (TG) is higher than in patients without Clinical signs.

Abstract
Background: In this study, we investigated the diagnostic power of ultrasound in the diagnosis of malignancy in thyroid nodules in Iranian patients. For this purpose, we examined the relationship between ultrasound findings and pathology findings.
Methods: The present study is a retrospective study. The patients with a diagnosis of thyroid nodules who underwent ultrasound and FNA, were included in this study. To assess the relationship between the results of FNA and the ultrasound characteristics of nodules, we classified the results of FNA into malignant and benign groups and then compared ultrasound characteristics between the two groups. In cases which the FNA results were indeterminate (AUS/FLUS or FN/SFN), the postoperative pathology result was considered (if thyroid surgery was done and the result was available).
Results: In total, 201 nodules were included in this study. The results showed that hypoechogenicity, irregular/ill-defined margin, microcalcification, malignant flow pattern in Doppler sonography and concurrent cervical lymphadenopathy with suspicious features were significantly associated with malignant thyroid nodules. However, other ultrasound findings, such as the size and location of the nodule, presence of a cystic components within the nodule, the presence of a Halo sign, and the presence of a taller-than-wide shape, could not distinguish between benign and malignant nodules. Finally, the results of the present study showed that the accuracy of ultrasound in the diagnosis of malignancy in thyroid nodules is high.
Conclusion: This study suggests that the use of ultrasound can be very effective in diagnosing malignancy in thyroid nodules.
