1.  Granulosa cell tumor in a six-year-old girl presented as precocious puberty 
Ovarian sex cord-stromal tumors, including granulose cell tumors (GCTs), are a group of neoplasms that occur rarely, especially in children. Only 0.1 percent of all ovarian tumors and 4-5 percent of GCTs occur in children. The most common presentation of these tumors in children is precocious puberty. We report a 6 years old girl with isosexual precocity, presented as premature thelarche and vaginal bleeding. Ultrasonography of pelvis showed a hypoechoic solid mass of left ovary.
Microscopic features of the resected mass were characteristic of juvenile GCT. Although in most of girls with precocious puberty, the etiology is idiopathic, important causes, such as ovarian tumors must be considered.

2.  Association between Serum Ferritin and Goitre in Iranian School Children 
Despite long-standing supplementation of iodine in Iran, the prevalence of goitre among general people remains high in some regions. The study investigated the role of iron status in the aetiology of goitre in school children in Isfahan, Iran. Two thousand three hundred and thirty-one school children were selected by multi-stage random sampling. Thyroid size was estimated by inspection and palpation. Urinary iodine concentration (UIC) and serum ferritin (SF) were measured. Overall, 32.9% of the children had goitre. The median UIC was 195.5 μg/L. The mean±SD of SF in the goitrous and non-goitrous children was 47.65±42.51 and 44.55±37.07 μg/L respectively (p=0.52). The prevalence of iron deficiency in goitrous and non-goitrous children was 9.6% and 3.1% respectively (p=0.007). Goitre is still prevalent in school children of Isfahan. However, their median UIC was well in the accepted range. Iron deficiency is associated with goitre in a small group of goitrous children. The role of goitrogens should also be investigated in this region.

3.  Outcome of Congenitally Hypothyroid Screening Program in Isfahan: Iran From Prevention to Treatment 
Objectives:
Early and proper treatment is crucial to prevent neuropsychologic deficits in congenital hypothyroidism (CH). Considering the high prevalence of CH in Isfahan, the aim of this study was to evaluate the outcome of treatment in CH patients.
Methods:
In this study CH neonates diagnosed during screening program in Isfahan from May 2002 to September 2009 were studied. Frequent visits were performed to CH patients to monitor and follow their treatments. Quality of treatment was assessed by evaluating mean age of treatment initiation and mean TSH and T4 levels before and after treatment and during the first and second years according to their normal reference ranges.
Results:
Of 225,224 screened neonates, 536 were diagnosed as CH patients. The prevalence of CH was 1/420 live births. Mean age at starting treatment was 22.9 ± 13.2 days. In 93.7% of patients, treatment was begun before the 45th day of life. In the first measurement after initiating the treatment, T4 and TSH were not in their acceptable range in 3.9% and 9.8% of CH patients, respectively. Mean T4 and TSH reached to normal range during the treatment period. T4 reached the normal range earlier than TSH.
Conclusions:
The mean age of treatment initiation was in acceptable range but the findings suggest that both early and high-dose treatments are crucial for optimal treatment, especially in patients with severe CH. Further studies are needed to determine the outcome of treatment specially regarding to different etiologies of CH.
