RESUMEN

BACKGROUND: Global variations in epidemiology of type 1 diabetes mellitus (T1DM) exist. This study is designed to examine demographic and clinical features of T1DM over the past 3 decades as well as evolving trends in epidemiology over last 50 years. METHODS: Clinical characteristics of 925 patients with T1DM over last 30 years (1990-2019) were evaluated and compared to previously published data of 477 patients diagnosed between 1969 and 1990 from one of the major referral centers for diabetes in Turkey. RESULTS: Mean age at diagnosis decreased from 9.5 ± 4.0 to 7.1 ± 3.6 years within the past 50 years (p < .001). Age at diagnosis peaked at 12-14 years between 1969 and 1990, then fell to 10-11.9 years between 1990 and 1999, and to 4-5.9 years between 2000-2009 and 2010-2019 (p = .005). Although the percentage of patients diagnosed <6 years of age is gradually increasing, the percentage between the ages of 6 and 11.9 years is decreasing, and the percentage diagnosed ≥12 years remained stable. A total of 47.5% of patients had ketoacidosis, 38.2% had ketosis, and 14.3% had only hyperglycemia. 23% of patients had severe diabetic ketoacidosis (DKA), whereas 42% had moderate. Over last 3 decades, there has been no change in frequency of ketoacidosis at presentation, but there has been significant decline in severity (p = .865, and p < .001, respectively). Although the frequency of patients with mild DKA increased over time, frequency of patients with moderate DKA decreased; however, no significant difference was observed among patients with severe ketoacidosis. DKA was more frequent and severe in patients <6 years of age (p = .005, and p < .001, respectively). CONCLUSION: Age at diagnosis shifted to younger ages in T1DM in the past 50 years. Half of patients had ketoacidosis at diagnosis and frequency of presentation with DKA did not decrease, but severity decreased slightly. Increase in prevalence of T1DM in the younger age group and the fact that half of patients present with DKA indicate that awareness should be increased in terms of early diagnosis and treatment.

RESUMEN

BACKGROUND: Hyperimmunoglobulin E syndrome (HIES) due to dedicator of cytokinesis8 (DOCK8) deficiency may present in infancy and childhood with different clinical features involving recurrent infections, allergic dysregulation, and autoimmunity. CASE: In this report, we describe a patient who first presented with severe hypereosinophilia and went on to develop the syndrome of inappropriate antidiuretic hormone secretion (SIADH) in the context of a severe herpes infection. Investigation revealed the presence of underlying DOCK8 deficiency presenting with atypical clinical features. CONCLUSIONS: Distinct inflammatory features associated with infections may be seen in the course of primary immunodeficiency diseases, and early functional and molecular genetic tests will aid the proper management.

RESUMEN

OBJECTIVE: Governments have enforced restrictions to prevent the spread of coronavirus dis- ease 2019, which has affected lifestyle and psychosocial well-being. The aim of this study is to examine the psychosocial dimensions of children with type 1 diabetes mellitus and lifestyle changes in the face of the pandemic. MATERIALS AND METHODS: Sixty school-aged children with type 1 diabetes mellitus were included to evaluate socioeconomic status, lifestyle changes, and psychological state after a 3-month school closure, using a questionnaire as well as scales in children and mothers [Depression-Anx iety-Stress Scale (short-form), Revised Child Anxiety-Depression Scale (parent-version), The Perceived Stress Scale in Children] via a Google® Form. The effect of pre-pandemic glycemic control on lifestyle and factors affecting HbA1c change were also investigated. RESULTS: The percentage of mothers having scale scores above the cutoff in terms of stress, anxiety, and depression were 18.3%, 23.3%, and 33.3%, respectively. Mother's and children's anxiety, depression, and stress scores were positively correlated. Employed mothers had higher depression scores. Paternal unemployment increased the anxiety of the mothers. Seventy-eight percent (n = 46) of the mothers thought that diabetes in their children increased the risk of coro- navirus disease 2019 infection, and children of these mothers had higher depression, anxiety, and stress scores(P = .01, P < .01, P < .01). The majority of participants were adversely affected by coronavirus disease 2019 in terms of daily routines and dietary compliance. Patients with poor-controlled type 1 diabetes mellitus deteriorated more in terms of diet compliance (P = .01). CONCLUSION: Coronavirus disease 2019 affects the psychosocial dimensions in the family of chil- dren with type 1 diabetes mellitus. The psychosocial impact is reflected within the family and may affect diabetic control. Thus, it should be handled within the context of family. The provi- sion of proper information and guidance to parents may be crucial to alleviate the psychosocial burden on the family during the pandemic.

RESUMEN

Objective: Phosphomannomutase 2 deficiency (PMM2-CDG) is a disorder of protein N-glycosylation with a wide clinical spectrum. Hypoglycemia is rarely reported in PMM2-CDG. In this study, we evaluated cause, treatment options and outcomes in cases with hypoglycemia in the course of PMM2-CDG. Methods: Clinical records of patients followed with PMM2-CDG within the last two decades were reviewed. Medical data of patients with hypoglycemia were evaluated in more detail. Demographic and clinical findings, organ involvement and laboratory investigations at time of hypoglycemia were recorded. Time of first attack of hypoglycemia, cause, treatment modalities, duration of hypoglycemia (permanent/transient), and duration of treatment, as well as outcome were also recorded. Other published cases with PMM2-CDG and hypoglycemia are also reviewed in order to elucidate characteristics as well as pathophysiology of hypoglycemia. Results: Nine patients with PMM2-CDG were reviewed, and hypoglycemia was present in three cases. All three had hyperinsulinism as the cause of hypoglycemia. In the first two cases reported here, serum insulin level concurrent with hypoglycemic episodes was elevated, and glucose response was exaggerated during glucagon test, favoring hyperinsulinism. However, in the third case, the serum insulin level at time of hypoglycemia was not so high but hypoglycemia responded well to diazoxide. Hyperinsulinism was permanent in two of these three cases. No genotype-phenotype correlation was observed with respect to hyperinsulinism. Conclusion: The main cause of hypoglycemia in PMM2-CDG appears to be hyperinsulinism. Although insulin levels at the time of hypoglycemia may not be very high, hypoglycemia in patients with PMM2 responds well to diazoxide.

RESUMEN

A genetic defect of 11 ß-hydroxysteroid dehydrogenase causes apparent mineralocorticoid excess syndrome. Since 50 days of life, our patient was hospitalized several times for various reasons including hypokalemia. At the age of 3.3 years, she was diagnosed with severe hypertension (160/120 mmHg). She also had left ventricular hypertrophy and hypertensive retinopathy and referred to our center. Her renal function and electrolytes were normal except for hypokalemia. She was on captopril treatment; nifedipine and propranolol were added. Plasma renin and aldosterone concentrations were 1.13 pg/ml (1-8.2 pg/ml) and 12.2 ng/dl (35-300 ng/dl), respectively. Severe hypertension, hypokalemia, low renin and aldosterone levels pointed to the diagnosis of apparent mineralocorticoid excess syndrome. Strict salt-restricted diet and potassium citrate were ordered. Genetic analysis of the HSD11B2 gene showed c.623G>A (p.Arg208His). Spironolactone was initiated. On follow-up, amiloride was added and her blood pressure was controlled. In patients with severe HSD11B2 mutation, combination therapy of spironolactone with amiloride could be effective in controlling blood pressure.

RESUMEN

Objective: Estrogen-secreting adrenocortical tumors (ACTs) are quite rare with feminizing adrenocortical tumors (FATs) accounting for 0.37-2% of all ACTs. The aim was to evaluate clinical and hormonal characteristics of FATS as well as treatment options and follow-up in the pediatric age group. Methods: Medical records of children with ACTs presenting to a single center in the last two decades were reviewed. Literature review within Pubmed revealed 34 pediatric patients (22 boys) with FAT among 192 articles. Results: Among the 25 children presenting with ACTs in the last two decades, two new pediatric cases of FAT were identified, one benign and the other malignant, in two genders with different clinical presentations. Literature review showed that FATs are extremely rare tumors that are most commonly seen in men and boys presenting with gynecomastia. FATs are more common in children ≤8 years of age, with a median age at diagnosis of six years. While boys present with contrasexual pseudopuberty signs, girls present with isosexual pseudopuberty. A high estrogen level strongly supports diagnosis, while elevations in other adrenal hormones may be seen. FATs are usually malignant in adults and prognosis is generally very poor. However, in children approximately half are benign although assessment of malignant potential depends on clinical behavior of the tumor. FATs are very unpredictable so even after surgery long-term follow-up is required. FATs presenting in childhood may have a better prognosis than adult presentation tumors as most FATs in children are followed without recurrence of tumor. Conclusion: FATs are more common in children ≤8 years of age, with a median age at diagnosis of six years. FATs in childhood may have a better prognosis than in adult males.

RESUMEN

AIM: Pheochromocytoma (PCC) and paraganglioma (PGL) are rare tumors in childhood. They are catecholamine secreting tumors and present with signs or symptoms related to their excess. Most common signs and symptoms are hypertension, headache and diaphoresis. The management of children usually depend on experience of adulthood. This study is conducted to present the clinical characteristics, surgical management and outcome of childhood PCC and PGL in a tertiary care center. MATERIAL AND METHODS: We reviewed clinical records of all patients operated for PCC and PGL between 2000 and 2020 retrospectively. RESULTS: There were 18 children operated for PCC and PGL in the study period. The female to male ratio was 1:1. The median age at diagnosis was 13 (IQR, 9-15) years. The most common presenting symptoms were headache and diaphoresis. Hypertension was the most common sign. Three patients had von Hippel-Lindau (VHL). Tumors of two patients with VHL were detected during routine follow-up. Three patients had multifocal disease. Medical preparation for surgery was carried out in all patients. Antihypertensive treatments were administered preoperatively. Since the patients are at risk for postoperative hypotension due to chronic vasoconstriction and blood volume contraction, high salt diet was recommended. Intravenous normal saline at a rate of 3000 ml/m2 body surface area per day was started for intravascular volume expansion preoperatively. The mean duration for preoperative medication to achieve normal blood pressure was 22 days (range, 16-30). Twenty-five tumors were excised in eighteen patients. One patient who had bone metastases on diagnosis and is on I131MIBG therapy. The median follow-up time was 5.6 years (range, 1 months - 21 years). Five patients reached adulthood during the study period. Four of these had recurrent metastases (n = 2) and new tumors (pancreatic neuroendocrine tumor, n = 1 and pancreatic neuroendocrine tumor and renal cell carcinoma, n = 1) after the age of 18. CONCLUSION: Multidisciplinary approach is necessary to achieve safe surgical treatment and surveillance of PCC and PGL. Detection of associated familial cancer susceptibility syndromes and long-term follow-up is essential to detect late recurrences and new tumors.

RESUMEN

OBJECTIVE: Data about GnRHa on adult height in girls with central precocious puberty (CPP) have shown variable results, ranging from improvement of growth prognosis to lack of any benefit. This study was designed to delineate the criteria to decide which girls with idiopathic CPP (iCPP) will have a height benefit from GnRHa treatment. DESIGN: Retrospective PATIENTS: 102 girls with iCPP who had reached final height (FH) were included. MEASUREMENTS: Auxological, hormonal and radiological findings at treatment onset, and FHs were extracted from records. RESULTS: Most important factor affecting height gain was chronological age (CA) at treatment onset. All the girls treated ≤6.4 years of age achieved a height gain of ≥1SDS, while none of the girls treated ≥8.3 years of age made the target. 75.6% of patients who started GnRHa between the ages of 6.4 and 8.3 years had a height gain of ≥1SDS. Most important factors affecting height gain in those treated 6.4-8.3 years were advanced bone age (BA), basal estradiol (E2 ) and pubertal stage (r2 : 0.906; P < .001). All individuals with BA advancement of ≥2.6 years or E2 of ≥32.6 pg/ml or pubertal stage of ≥3 had significant height gain, and none of the cases with BA advancement of <2 years or E2 of <21.5 pg/ml or pubertal stage of <2 had a height gain of ≥1SDS. CONCLUSIONS: Treatment with GnRHa is unquestionably beneficial to improve FH in girls with iCPP when initiated ≤6.4 years of age. GnRHa treatment after 8.3 years of age may not improve FH. Girls between the ages of 6.4 and 8.3 years at presentation can have a better height gain if BA (≥2.6 years over CA) and pubertal findings (pubertal stage ≥3 or E2 ≥32.6 pg/ml) are well-advanced.

RESUMEN

BACKGROUND: Adrenocortical tumours (ACT) are rare tumours of childhood usually presenting with endocrine dysfunction. This retrospective study is designed to review our institutional experience in surgical management. METHODS: Records of children treated for ACT between 1999 and 2019 were reviewed retrospectively. RESULTS: The median age of 24 children was 78 months. Fourteen patients had adrenocortical carcinoma, nine had adrenocortical adenoma and one had neuroendocrine differentiation of ACT. Endocrine dysfunction was noted in 79% of the patients. Five patients had preoperative chemotherapy but none had a decrease in tumour size. Transabdominal approach was used in all but two patients who had thoracoabdominal incision for excision of giant tumours and ipsilateral lung metastases. Two patients had visceral excision to achieve R0 resection. Five patients, four of whom had spillage and one with partial resection died of widespread disease. Two patients with stage 4 adrenocortical carcinoma are still on chemotherapy. All patients with stage I-III disease who had total excision without spillage (n = 17) are disease-free for 2-170 months. CONCLUSIONS: Our results show the importance of excision in ACT without spillage for survival. However, multicentre prospective studies should enhance the knowledge of children about ACT and develop alternative therapies for stage III and IV cases.

RESUMEN

OBJECTIVE: The purpose of this study was to investigate the peripheral concentrations of leptin and neuropeptides taking part in the melanocortin pathway in hypothalamic obesity (HO) associated with craniopharyngioma (CP) and to find a peripheral marker for diagnosis. METHODS: Thirty-one patients (52% girls; median age 16 years) with CP were enrolled in the study group. They were grouped as CP with obesity (CPobesity , n = 17) and CP without obesity (CPnonobesity , n = 14). Two control groups without CP consisted of 27 children with obesity (OC) (55% girls; median age 13.8 years) and 25 children without obesity (normal control [NC]) (72% girls; median age 14.5 years). Obesity was defined as BMI percentile ≥ 95%. Fasting serum concentrations of leptin, brain-derived neurotrophic factor (BDNF), and alpha-melanocyte-stimulating hormone (α-MSH) were measured in the groups. RESULTS: Leptin and BDNF concentrations were correlated with BMI SD score (SDS) in controls (OC + NC) and CP. However, there was no correlation between α-MSH and BMI-SDS in CP or control groups. After adjusting for age, sex, and BMI-SDS, α-MSH was found to be significantly higher in CPobesity than in other groups, whereas leptin and BDNF were comparable among the four groups. CONCLUSIONS: Serum BDNF, just like leptin, increased with BMI, regardless of hypothalamic damage. On the contrary, α-MSH concentration was significantly high in HO, designating a potential biomarker for HO in CP.

RESUMEN

OBJECTIVES: Osteogenesis imperfecta type VI (OI VI) follows a progressive and severe course, yet unlike other forms of severe OI it has a later onset of fractures, and extra-skeletal findings are not part of the clinical picture. Another difference is that there is an increase in unmineralized osteoid tissue in OI VI, which hinders the effect of bisphosphonates-the current standard of treatment for OI. Therefore, the response to standard treatments in OI VI is not satisfactory. Herein, we report long-term follow-up of two cases with novel SERPINF1 mutations, who show great variation in their treatment response to bisphosphonates. CASE PRESENTATION: The first case was given pamidronate at the age of 15 months when he could sit independently, followed a fluctuating course under treatment, fracture rate did not decrease, however he was able to mobilize with walker at the age of 10 years. On the other hand, the second case developed severe deformities and became wheelchair-bound under pamidronate, thus the treatment was switched to denosumab. Unfortunately, there was no improvement under denosumab after 15 months too, and since bone pain increased, denosumab treatment was stopped. He was put on zoledronic acid instead. CONCLUSION: SERPINF1 transcript amount may be an important factor to explain the variation in response to pamidronate therapy. In OI VI patients, the factors affecting the clinical course should be identified and new or combined treatment options should be established.

RESUMEN

INTRODUCTION: Hypothalamic obesity (HO) is a type of obesity that is caused by hypothalamic damage. HO can be complicated by obstructive sleep apnea syndrome (OSAS) due to anatomical narrowing of the upper airway and hypothalamic damage-induced dysfunction of the sleep control mechanisms. We aimed to explore the presence and severity of OSAS in children with HO and hypothesized that OSAS is more severe and frequent in HO than exogenous obesity (EO). METHODS: This cross-sectional study was conducted among children aged 6.6-17.9 years. Subjects with HO (n = 14) and controls with EO (n = 19) were consecutively recruited through an endocrinology clinic. All patients underwent full-night polysomnography. The primary outcomes were obstructive apnea-hypopnea index (OAHI) and the severity of OSAS. We analyzed the polysomnography findings, biochemical parameters, Brodsky and modified Mallampati scores, and blood pressure compared with the controls. We explored the different obesity types and these variables in association with OAHI using multiple linear regression (MLR). RESULTS: Age and body mass index z scores (BMI-z) were similar between the EO and HO groups. The OAHI of HO (5.8) was higher than that of EO (2.2). In MLR, the predicted OAHI was formulated as an equation using regression coefficients of obesity type (HO), age, and BMI-z (R2 = .41). In the logistic regression analysis, the odds ratio of moderate/severe OSA was 5.6 for HO. CONCLUSIONS: Children with HO have a higher risk of moderate/severe OSAS than children with EO. Polysomnography should be considered in all patients with HO.

RESUMEN

BACKGROUND AND OBJECTIVES: Congenital adrenal hyperplasia (CAH) is characterized by androgen excess which should be treated with life-long glucocorticoid therapy, thus can affect bone mineralization. We aimed to evaluate the bone mineral density (BMD) and determine the factors affecting bone mineralization in patients with CAH. METHOD: This prospective case-control study was conducted in children, adolescents and young adults with classical 21-hydroxylase CAH, and age-, sex-, and pubertal stage matched healthy controls. Lumbar1-4 BMD was determined by dual-energy X-ray absorptiometry. BMD z-score was calculated using national standards with respect to height age and was referred as `low BMD` if z-score < -1 SD. Univariate analyses were performed between low BMD and normal BMD groups, and multivariate logistic regression analysis was performed to assess the independent predictors of low BMD. Correlations of Body Mass Index (BMI)-z-score, average serum 17-hydroxyprogesterone level, duration of treatment, average and cumulative glucocorticoid doses with BMD z-score were evaluated with Spearman analyses. RESULTS: Each group included 37 cases. BMD z-score of patients with CAH [0.47 (-0.04 - 1.56)] was higher than control group [-0.43 (-0.82 -0.05)]; p= < 0.001. Number of patients with low BMD was similar in both groups; [CAH: 6(16.2%), control: 5(13.5%); p= 0.744]. BMI- z-score was higher in patients with CAH when compared to control group; p= < 0.001. BMI z-score was lower in low BMD group as comparison to normal BMD group; p= 0.041. Each 1.0 decrease in BMI z-score, risk of having low BMD was found to increase by 1.79 (%95 CI: 1.03- 3.12, p= 0.040). BMI-z-score, average serum 17-hydroxyprogesterone level, duration of treatment, average and cumulative glucocorticoid doses were not found to be correlated with BMD z-score. CONCLUSION: Long-term glucocorticoid therapy did not have negative effect on BMD of patients with CAH. Higher BMI z-score in patients with CAH may have a positive effect on preserving bone health. Precautions should be taken for increased risk of obesity.

RESUMEN

Objective: Doses of gonadotropin releasing hormone (GnRH) analogues used to treat idiopathic central precocious puberty (iCPP) vary among clinicians. Study aims were to evaluate the efficacy of a monthly 3.75 mg dose of leuprolide acetate (LA) to suppress the hypothalamo-pituitary-gonadal (HPG) axis in girls with iCPP and to determine factors that may have an impact on the supressing dose. Methods: Study subjects were 220 girls receiving LA for iCPP. LA was started at a dose of 3.75 mg/28 days. Suppression was assessed using the GnRH test at the third month. To assess clinical suppression signs and symptoms of puberty were also evaluated. The dose of LA was increased to 7.5 mg/28 days in those who had a peak luteinising hormone (LH) ≥2 IU/L and in whom adequate clinical suppression of puberty was absent. Receiver operating characteristic curves were used to determine thresholds for clinical and hormonal factors affecting the suppressing dose of LA. Logistic regression analyses were used to investigate thresholds which might differentiate between those requiring high dose for suppression and those in whom lower dose LA was adequate. Results: Peak stimulated LH <2 IU/L was achieved in 88.6% with a dose of LA of 3.75 mg (0.11±0.03 mg/kg). Significant variables for differentiating the two doses were body weight (Wt) of 36.2 kg and/or body mass index (BMI)-standard deviation scores (SDS) of 1.64 (p<0.001). Multiple logistic regressions showed that Wt and BMI-SDS values above thresholds indicated requirement of LA at a dose of 7.5 mg/28 days (p<0.001). Conclusion: Monthly injections of 3.75 mg LA is an effective treatment in the majority of girls with iCPP. However, a higher initial dose may be preferred in patients with a Wt ≥36 kg or BMI-SDS ≥1.6 for effective suppression of the HPG axis.

RESUMEN

3M syndrome is characterized by severe pre- and postnatal growth retardation, typical facial features, and normal intelligence. Homozygous or compound heterozygous mutations in either CUL7, OBSL1, or CCDC8 have been identified in the etiology so far. Clinical and molecular features of 24 patients (23 patients and a fetus) from 19 unrelated families with a clinical diagnosis of 3M syndrome were evaluated and genotype-phenotype correlations were investigated with the use of DNA sequencing, chromosomal microarray, and whole exome sequencing accordingly. A genetic etiology could be established in 20 patients (n = 20/24, 83%). Eleven distinct CUL7 or OBSL1 mutations, among which eight was novel, were identified in 18 patients (n = 18/24, 75%). Ten patients had CUL7 (n = 10/18, 56%) while eight had OBSL1 (n = 8/18, 44%) mutations. Birth weight and height standard deviation scores at admission were significantly (p < 0.05) lower in patients with CUL7 mutation compared to that of patients with OBSL1 mutation. Two patients with a similar phenotype had a de novo 20p13p deletion involving BMP2. No genetic etiology could be established in four patients (n = 4/28, 17%). This study yet represents the largest cohort of 3M syndrome patients from a single center in Turkey. Microdeletions involving BMP2 may cause a phenotype similar to 3M syndrome with some distinctive features. Larger cohort of patients are required to establish genotype-phenotype correlations in 3M syndrome.

RESUMEN

BACKGROUND: COQ2 mutations cause a rare infantile multisystemic disease with heterogeneous clinical features. Promising results have been reported in response to Coenzyme Q10 treatment, especially for kidney involvement, but little is known about the long-term outcomes. METHODS: We report four new patients from two families with the c.437G→A (p.Ser146Asn) mutation in COQ2 and the outcomes of two patients after long-term coenzyme Q10 treatment. RESULTS: Index cases from two families presented with vomiting, nephrotic range proteinuria, and diabetes in early infancy. These patients were diagnosed with coenzyme Q10 deficiency and died shortly after diagnosis. Siblings of the index cases later presented with neonatal diabetes and proteinuria and were diagnosed at the first day of life. Coenzyme Q10 treatment was started immediately. The siblings responded dramatically to coenzyme Q10 treatment with normalized glucose and proteinuria levels, but they developed refractory focal clonic seizures beginning at three months of life that progressed to encephalopathy. CONCLUSIONS: In our cohort with CoQ10 deficiency, neurological involvement did not improve with oral coenzyme Q10 treatment despite the initial recovery from the diabetes and nephrotic syndrome.

RESUMEN

Background Adolescents with type 1 diabetes mellitus (T1DM) are at an increased risk of eating disturbances. The aim of this study was to evaluate whether the risk of a disordered eating behavior (DEB) also applies to the well sibling sharing the same environment. Methods Well siblings were included if they were 10-18 years old, had a sibling with a T1DM diagnosis for at least 6 months and lived with the sibling during the illness. The control group was comprised of healthy participants recruited from the outpatient clinic with no family history of T1DM. Participants completed a four-part questionnaire concerning their eating behaviors that was developed by the study team. This survey aimed to evaluate the dietary habits and eating patterns. All participants completed the Eating Attitudes Test-26 (EAT-26) and a 24-h food dietary recall. Any participant with a high EAT-26 score or that seemed to be at risk according to the questionnaire was re-evaluated. Results Eight cases (33.3%) in the well sibling group had either a total and/or subgroup pathological score. Three of them were found to have DEB and one case was diagnosed with anorexia nervosa (AN). In the control group, five cases (17.2%) had either a total and/or subgroup pathological score. Three of these cases were found to have DEB, no cases were diagnosed with an eating disorder. There were no statistically significant differences in the EAT-26 scores between the groups. Conclusions Although a direct relationship was not observed, the probability of having a pathologic EAT-26 score was higher in the group with a sibling with T1DM.

RESUMEN

Disorders of sex development are defined as conditions in which the chromosomal, gonadal, and anatomic sex is discordant. Patients usually present with atypical appearing genitalia. In the assessment of neonates with disorders of sex development, first, it is important to determine whether this situation requires prompt evaluation, and then the karyotype, hormone levels, and underlying etiology should be determined as soon as possible. All these procedures should be performed in the guidance of a multidisciplinary team in reference centers. As the physical examination of the infant is extremely important, the physcian should suspect and then perform a detailed history and physical examinationi and lastly plan the required laboratory and imaging procedures for the definite diagnosis. It is important not to be hurried in the choice of sex. The aim of this article, which includes the diagnostic and therapeutic approaches in infants with ambiguous genitalia, was to provide a common practice for all pediatricians.

RESUMEN

Vuralli D, Kandemir N, Clark G, Orhan D, Alikasifoglu A, Gönç N, Ekinci S, Özön A. A pheochromocytoma case diagnosed as adrenal incidentaloma. Turk J Pediatr 2017; 59: 200-206. There are two problems that needs to be addressed in cases of an adrenal incidentaloma. The first is to decide whether the adrenal mass is benign or malignant, and the second is to determine whether the mass is hormonally active or not. A 17-year-old male was admitted with the complaint of progressive weight gain. Abdominal ultrasonography was performed for elevation in transaminases which revealed a hypoechoic mass located in the left adrenal gland. Hormonal investigations revealed an increase in fractionated catecholamine and metanephrine levels in 24-hour urine. Surgery was performed and pathological examination was in accordance with pheochromocytoma. Mutation analysis was carried out. This is a rare case of pheochromocytoma presenting as adrenal incidentaloma during adolescence. In view of this case, we review the approach to incidentally discovered adrenal masses and the approach to pheochromocytoma. A mutation analysis should be performed on all cases with pheochromocytoma that are diagnosed below age 20.
