Objective: Maturity onset diabetes of the young (MODY) occurs due to mutations in genes involved in pancreatic beta cell function and insulin secretion, has heterogeneous clinical and laboratory features, and account for 1-5% of all diabetes cases. The prevalence and distribution of MODY subtypes vary between countries. The aim of this study was to evaluate the clinical and laboratory characteristics, mutation distribution, and phenotype-genotype relationship in a large case series of pediatric Turkish patients genetically diagnosed with MODY. Methods: MODY cases from 14 different pediatric endocrinology departments were included. Diagnosis, treatment, follow-up data, and results of genetic analysis were evaluated. Results: A total of 224 patients were included, of whom 101 (45%) were female, and the mean age at diagnosis was 9.4±4.1 years. Gene variant distribution was: 146 (65%) GCK; 43 (19%) HNF1A; 8 (3.6%) HNF4A, 8 (3.6%) KLF11 and 7 (3.1%) HNF1B. The remaining 12 variants were: PDX (n=1), NEUROD1 (n=3), CEL (n=1), INS (n=3), ABCC8 (n= 3) and KJNC11 (n=1). Of the cases, 197 (87.9%) were diagnosed with incidental hyperglycemia, 16 with ketosis (7%) and 7 (3%) with diabetic ketoacidosis (DKA), while 30% presented with classical symptoms of diabetes. Two-hundred (89%) had a family history of diabetes. Anti-GAD antibody was detected in 13 cases, anti-islet antibody in eight and anti-insulin antibody in four. Obesity was present in 16. Distribution of therapy was: 158 (71%) diet only; 23 (11%) intensive insulin treatment; 17 (7.6%) sulfonylureas; 10 (4.5%) metformin; and 6 (2.7%) insulin and oral anti-diabetic treatment. Conclusion: This was the largest genetically diagnosed series from Turkey. The most common gene variants were GCK and HNF1A with much lower proportions for other MODY types. Hyperglycemia was the most common presenting symptom while 11% of patients had diabetes-associated autoantibodies and 7% were obese. The majority of patients received dietary management only.

Coronavirus disease 2019 has caused a major epidemic worldwide, and lockdowns became necessary in all countries to prevent its spread. This study aimed to evaluate the effects of staying-at-home practices on the metabolic control of children and adolescents with type 1 diabetes during the pandemic period. Eighty-nine patients younger than 18 years old who were diagnosed with type 1 diabetes at least one year before the declaration of the pandemic were included in the study. The last visit data of the patients before and after the declaration of the pandemic, and the frequency of presentation of diabetes-related emergencies from one year after diagnosis of type 1 diabetes to the declaration of the pandemic, and from the declaration of the pandemic to the last visit after the pandemic declaration were compared. The total number of patients was 89, and 48 (53.9%) were boys. The mean (± standard deviation [SD]) age at diagnosis was 8.4 ± 3.7 years (boys 7.9 ± 3.6 years; girls 8.9 ± 3.9 years). There was no statistically significant difference when the SD values of the anthropometric measurements, and the glycosylated hemoglobin (HbA1c) and lipid profile tests were compared. However, the frequency of admission to the emergency service related to diabetes was significantly different. Although the pandemic did not significantly affect the metabolic and glycemic controls of the children with type 1 diabetes included in this study, an increase in the frequency of diabetes-related emergency admissions was noted.

IMAGe syndrome is an acronym which stands for the intrauterine growth restriction (IUGR), metaphyseal dysplasia, adrenal hypoplasia congenita (AHC) and genitourinary abnormalities. Congenital adrenal hypoplasia is the most serious component of the syndrome which generally occurs during the first months of life. In the presented case, shortness of extremities was detected antenatally and the symptoms of adrenal failure showed up on the 4th day of life. Because the adrenal insufficiency is a life-threatening condition, early diagnosis of this syndrome is very important. Recognition of other components of the disease makes early intervention possible. Being a rare disease, a case with IMAGe syndrome is presented with a short review of the literature.

Introduction: Proportional short stature is one of the most important features of Noonan Syndrome, and adult height often remains below the 3rd percentile. Although the pathophysiology of short stature in NS patients is not fully understood, it has been shown that GH treatment is beneficial in NS, and it significantly improves the height in respect to the results of short and long-term GH treatment., Methods: In this study, the efficacy of GH therapy was evaluated in children and adolescents with Noonan syndrome who attained final height. In this national cohort study, 67 cases with NS who reached final height from 14 centers were evaluated., Results: A total of 53 cases (mean follow-up time 5.6 years) received GH treatment. Height SDS of the subjects who were started on GH tended to be shorter than those who did not receive GH (-3.26± 1.07 vs. -2.53 ±1.23) at initial presentation. The mean final height and final height SDS in girls using GH vs those not using GH were 150.1 cm and -2.17 SD vs 47.4 cm and-2.8 SD, respectively. The mean final height and final height SDS in boys using GH vs. not using GH were 162.48 ± 6.19 cm and -1.81 SD vs 157.46 ± 10.16 cm and -2.68 ± 1.42 SD, respectively. The Δheight SDS value of the cases was significantly higher in the group receiving GH than in those not receiving GH (1.36 ± 1.12 SD vs. -0.2 ± 1.24, p<0.001). Cardiac findings remained stable in two patients with hypertrophic cardiomyopathy who received GH treatment. No significant side effects were observed in the cases during follow-up., Conclusion: In patients with Noonan syndrome who reach their final height, a significant increase in height is observed with GH treatment, and an increase of approximately +1.4 SDS can be achieved. It has been concluded that GH treatment is safe and effective.
