Brain Atrophy and Hypomyelination Associated with Iatrogenic Cushing’s Syndrome in an Infant

Prolonged use of topical corticosteroids, particularly in infants, albeit rare, may lead to Cushing's syndrome. Central nervous system abnormalities including brain atrophy and delayed myelination on cranial magnetic resonance imaging has been reported in patients with corticosteroid treatment. We herein report a 5-month-old female infant with brain atrophy and myelination delay that might be due to iatrogenic Cushing's syndrome caused by topical corticosteroid use

Evaluation of Adrenomedullary Function in Patients with Congenital Adrenal Hyperplasia

Background/Aims: Congenital adrenal hyperplasia (CAH) is characterized by adrenal insufficiency with or without salt wasting. It is also accompanied by adrenomedullary hypofunction. The aim of the present study was to investigate adrenomedullary function in patients with CAH due to 21-hydroxylase and 11 beta-hydroxylase deficiencies and in age-matched normal subjects. Methods: We measured plasma catecholamines (epinephrine and norepinephrine) and urine metanephrine in 44 patients with CAH, 32 due to 21-hydroxylase deficiency (17 patients with the salt-wasting form and 15 patients with the simple virilizing form), and 12 due to 11 beta-hydroxylase deficiency, and in 25 healthy controls. Results: Plasma epinephrine and urine metanephrine levels were significantly higher in the controls than in patients with CAH (p = 0.02 and p < 0.001, respectively). Plasma norepinephrine levels were significantly lower in the controls than in patients with CAH (p < 0.001). Interestingly, patients with the salt-wasting form had lower norepinephrine levels in comparison to the other subgroups of CAH. Conclusion: Despite the fact that CAH patients have insufficient epinephrine secretion, these patients have the ability to increase compensatory norepinephrine. However, this increase is much lower in patients with the salt-wasting form. These findings need to be confirmed by other studies. Copyright (C) 2009 S. Karger AG, Base

Brain atrophy and hypomyelination associated with Iatrogenic cushing syndrome in an infant

Prolonged use of topical corticosteroids, particularly in infants, albeit rare, may lead to Cushing syndrome. Central nervous system abnormalities including brain atrophy and delayed myelination on cranial magnetic resonance imaging has been reported in patients with corticosteroid treatment. We herein report a 5-month-old female infant referred to Department of Pediatric Endocrinology, Edirne, Turkey with brain atrophy and myelination delay that might be due to iatrogenic Cushing syndrome caused by topical corticosteroid use

A Synopsis of Current Practice in the Diagnosis and Management of Patients with Turner Syndrome in Turkey: A Survey of 18 Pediatric Endocrinology Centers

Objective: A comprehensive survey was conducted to evaluate the shortcomings of clinical care in patients with Turner syndrome (TS) in Turkey. Methods: A structured questionnaire prepared by the Turner study group in Turkey, which covered relevant aspects of patient care in TS was sent to 44 pediatric endocrinology centers. Results: Eighteen centers (41\%) responded to the questionnaire. In the majority of the centers, diagnostic genetic testing, screening for Y chromosomal material, protocols regarding the timing and posology of growth hormone (GH) and estrogen, thrombophilia screening, fertility information and screening for glucose intolerance, thyroid, and coeliac diseases in patients with TS were in line with the current consensus. Thirteen centers (72.2\%) performed GH stimulation tests. Only four centers (22.2\%) used oxandrolone in patients with TS with very short stature. The majority of the centers relied on bone age and breast development to assess estrogen adequacy, though together with variable combinations of oestrogen surrogates. Two centers (11.1\%) reported performing serum estradiol measurements. Eight centers (44.4\%) routinely conducted cardiac/thoracic aorta magnetic resonance imaging. Screening for hearing, dental and ophthalmologic problems were performed by thirteen (72.2\%), six (33.3\%) and ten (55.6\%) centers, respectively. Psychiatric assessments were made by four centers (22.2\%) at diagnosis, with only one center (5.6\%) requiring annual reassessments. Conclusion: Although we found some conformity between the current consensus and practice of the participating centers in Turkey regarding TS, further improvements are mandatory in the multi-disciplinary approach to address co-morbidities, which if unrecognized, may be associated with reduced quality of life and even mortality

Evaluation of therapeutics management patterns and glycemic control of pediatric type 1 diabetes mellitus patients in Turkey: A nationwide cross-sectional study

WOS: 000381646900004PubMed ID: 27423071Aims: To evaluate the management strategies, glycemic control and complications of pediatric type 1 diabetes mellitus (T1DM) patients in Turkey. Methods: Study included 498 patients with T1DM between the ages 1-18. Data provided from patients' hospital files were recorded on standard case report forms by applicant clinicians within the 3 months of data collection period between October 2012 and July 2013. Results: Mean age of patients was 11.3 +/- 3.8 years. Mean duration of DM was determined as 3.7 +/- 3.1 years. Majority of patients (85.5%) used basal/bolus injection (BBI), and 6.5% used continuous subcutaneous insulin infusion pump. Assessment of glycemic control based on HbA1c levels showed that 29.1% of patients had an HbA1c value 9%(75 mmol/mol). Hypoglycemia was reported in 145 (29.1%) patients and the number of severe hypoglycemic attacks in the last 3 months was 1.0 +/- 2.4. Taking into consideration the carbohydrate count and insulin correction dose and parents with high socioeconomic status was related to have better glycemic control. The most common comorbidities were Hashimoto's thyroiditis/hypothyroidism (6.2%) followed by celiac disease (3.8%), epilepsy(1.2%), and asthma(1.0%). Conclusions: BBI insulin therapy is widely used among pediatric T1DM patients in Turkey. However, despite improvements in treatment facilities and diabetic care, glycemic control is not at a satisfactory level. Therefore, new and comprehensive initiatives require for pediatric T1DM patients with poor glycemic control. Promoting use of carbohydrate count and insulin correction doses may improve the glycemic control of pediatric T1DM in Turkey. (C) 2016 Elsevier Ireland Ltd.

The Etiology and Clinical Features of Non-CAH Gonadotropin-Independent Precocious Puberty: A Multicenter Study

WOS: 000378819700011PubMed ID: 26964727Aim: The causes of gonadotropin-independent precocious puberty are diverse, and often have overlapping clinical and biochemical features. With the exception of congenital adrenal hyperplasia (CAH), disorders that cause gonadotropin-independent precocious puberty (GIPP) are uncommon. The literature is devoid of any large-scale studies on the etiologic distribution of GIPP. The aim of this study was to determine the frequency of each etiology in a cohort of patients with GIPP (excluding those with CAH), and to evaluate the clinical and laboratory features of these patients. Materials and Methods: This multicenter, nationwide web-based study collected data on patients who presented with non-CAH GIPP in Turkey. Results: Data were collected for 129 patients (102 girls and 27 boys) from 29 centers. Based on the data collected, the estimated prevalence of non-CAH GIPP in the studied population was 14 in 1 000 000 children. Functional ovarian cyst was the most common etiology, accounting for 37% of all cases, followed by McCune-Albright syndrome (MAS) (26%). Among the patients with MAS, 11.7% had fibrous dysplasia, 32.3% had caf-au-lait spots, and 52.9% had both. Human chorionic gonadotrophin-secreting tumors included choriocarcinoma of the liver, hepatoblastoma, and germ cell tumors of the sellar-suprasellar region and mediastinum. Patients with adrenocortical tumors presented at an earlier age than those with other etiologies. Ovarian tumors included mature cystic teratoma, dysgerminoma, juvenile granulosa tumor, and steroid cell tumor. Despite overlapping features, it was possible to identify some unique clinical and laboratory features associated with each etiology. Conclusion: This largest cohort of patients with non-CAH GIPP to date yielded an estimation of the frequency of non-CAH GIPP in the general pediatric population and showed that girls were affected at a rate 4-fold greater than that of boys owing to functional ovarian cysts and MAS, which were the two most common etiologies. The data collected also provided some unique characteristics associated with each etiology.Turkish Pediatric Endocrinology and Diabetes Society [052014]This work was supported by the Turkish Pediatric Endocrinology and Diabetes Society (No: 052014)
