OBJECTIVE: Background: ADAMTS-1 is a matrix metalloproteinase which cleaves versican in the cumulus oocyte complex, under the effect of luteinizing hormone surge in the periovulatory period. Altered levels of it may have a role in the disease pathogenesis. OBJECTIVE: We aimed to detect serum versican and a disintegrin and metalloproteinase with thrombospondin motif- 1 (ADAMTS-1) levels in polycystic ovary syndrome (PCOS) patients, and compare the results with the healthy controls...

Peutz-Jeghers Syndrome (PJS) is inherited as an autosomal dominant trait which is characterized by multiple gastrointestinal hamartomatous polyps, mucocutaneous pigmentation, and an increased risk of neoplasm. Large Cell Calcifying Sertoli Cell Tumor (LCCSCT) is a kind of sex cord-stromal tumor, often bilateral and multifocal, accounting for 0.4 -1.5% of entire testicular tumors which may co-exist with PJS and is characterized radiologically by calcification foci within the testes. Surgical treatment options for this tumor range from testis-preserving surgery to radical orchiectomy...

: High doses of oral calcium or long-term calcium infusions are recommended to correct the hypocalcemia and secondary hyperparathyroidism in patients with hereditary 1-25 dihydroxyvitamin D3 resistant rickets (HVDRR). Preliminary studies revealed that calcimimetics may be safe and effective therapeutic choise in children with secondary hyperparathyroidism. Our aim was to observe the efficacy of cinacalcet on the normalization of secondary hyperparathroidism and hypophosphatemia in two siblings with VDRR who did not respond to traditional therapy regimes...

The 3M syndrome is a rare autosomal disorder that can lead to short stature, dysmorphic features and skeletal abnormalities with normal intelligence. A 16 months old female patient had been referred to our clinic due to short stature. Case history revealed a birth weight of 1740 grams on 39th week of gestation, with a birth length of 42 cm and no prior hereditary conditions of clinical significance in her family. On physical examination, her height was 67 cm (-3.6 SD score), body weight was 7.2 kg (-2.9 SD score) with a head circumference of 42 cm (below 3rd percentile)...

OBJECTIVE: Otitis media with effusion (OME) is a condition in which fluid is retained in the middle ear cavity, but without otalgia, fever, and other symptoms. The incidence of endocrinological disorders has been increasing, but the association between endocrinological disorders and OME has not yet been determined. In this study, it was aimed to investigate the presence of OME in children diagnosed with an endocrinological disease and their relationship with each other. METHODS: Our study was done with 918 children patients (440 boys, 478 girls; mean age: 8...

OBJECTIVE: To investigate the clinical and molecular features of three Chinese patients with various typical manifestations of congenital generalized lipodystrophy (CGL). METHODS: Clinical symptoms, results of laboratory analyses, and data on previous treatments in three Chinese patients were collected by retrospective review of medical records. All coding regions and adjacent exon-intron junction regions of AGPAT2 and BSCL2 genes were amplified by polymerase chain reaction and sequenced...

OBJECTIVE: The aim of this study was to investigate the depression-like behaviors of juvenile rats with congenital and postnatal hypothyroidism. METHODS: Twenty seven newborn rat pups were used. First, 6-month old Wistar Albino female rats were impregnated. Methimazole (0.025% wt/vol) was given to dam rats from the first day of pregnancy until postnatal 21 days (P21) to generate pups with congenital hypothyroidism (n=8), whereas in the postnatal hypothyroidism group (n=10) methimazole was given from P0 to P21...

OBJECTIVE: Congenital hypothyroidism (CH) is one of the most common treatable causes of mental retardation and neurodevelopmental impairment. METHODS: In a cross-sectional study, 114342 neonates born in 28 cities in Razavi Khorasan province, northeastern Iran from Aril 2013 to March 2014, were screened for congenital hypothyroidism by taking blood sample from heel prick.

OBJECTIVE: Thyroid abnormalities are common in obese children. The aim of the present study was to examine the prevalence of subclinical hypothyroidism (SH) and to determine how circulating thyroid hormone concentrations correlate with anthropometrics in Danish lean and obese children and adolescents. METHODS: We included 3,006 children and adolescents, aged 6-18 years, from the Registry of the Danish Childhood Obesity Biobank in this cross-sectional study. The overweight/obese group (n=1,796) consisted of study participants with a body mass index (BMI) standard deviation score (SDS) ≥1...

OBJECTIVE: Although polymorphisms in suppressor of cytokine signaling 3 (SOCS3) was reported to be related to obesity, metabolic syndrome and type 2 diabetes in various adult studies, there is a lack of data in children. In this study, we examined eight reported polymorphisms of SOCS3 in obese Turkish children with and without metabolic syndrome and compared the results with that of controls. METHODS: 148 obese and 63 age and sex matched control children were enrolled in the study...

OBJECTIVE: Cathelicidin is an important antimicrobial peptide in the urinary tract. Cathelicidin expression is strongly stimulated by 1,25-dihydroxy vitamin D in epithelial cells, macrophages/monocytes, and neutrophils. Vitamin D and cathelicidin status in children with urinary tract infection (UTI) caused by Escherichia coli is unknown. To establish the relationship between serum vitamin D and urine cathelicidin levels in children with a UTI caused by Escherichia coli. METHODS: Serum 25-hydroxy vitamin D and urine cathelicidin levels were measured in 36 patients with UTI (mean age 6...

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a common endocrine problem in adolescents with an increasing prevalence of 30%. Pursuing new biomarkers with high specificity and sensitivity in the diagnosis of PCOS in adolescents is currently an active area of research. We aimed to investigate the diagnostic value of anti-Müllerian hormone (AMH), insulin-like peptide-3 (INSL3), inhibin-A (INH-A), and inhibin-B (INH-B) in adolescents with PCOS and also to determine the association, if any, between these hormones and clinical/laboratory findings related with hyperandrogenism...

Isolated aldosterone synthase deficiency may result in life-threatening salt-wasting and failure to thrive. The condition involves hyperkalemia accompanying hyponatremia. Two types of aldosterone synthase deficiency may be observed depending on hormone levels: corticosterone methyl oxidase type 1 (CMO 1) and CMO 2. Herein, we describe a Turkish infant patient with aldosterone synthase deficiency who presented with failure to thrive and salt wasting but with normal potassium levels. Urinary steroid characteristics were compatible with CMO I deficiency...
