Introduction: The incidence of Cushing disease (CD) is 0.7-2.4/year per million, andadolescents and children make up 10% of new cases annually. However, thesensitivity and specificity of tests used to diagnose CD in childhood may bepoor, resulting in difficulties in diagnosis and treatment. The aim was to reportpediatric CD patients attending our pituitary referral center for surgery and todescribe their diagnosis, treatment and long-term follow-up.<p clas...

Introduction: Fulminant type 1 diabetes (FT1D) occurs because of a sudden and almost total destruction of pancreatic β-cells, triggered by a viral infection. FT1DM may cause diabetic ketoacidosis (DKA) and even sudden death. Thus prompt diagnosis is vital.Case Report: Antibiotic treatment was started for a 4-year-old female patient because of a fever and cough. On the second day of treatment, she was admitted with r...

46,XY disorders of sex development associated with MAP3K1variants: Case and review of the literature.

Koçyiğit Esra , Hürmüzlü Gözler Selen , Gürpınar Gözde , Kilci Fatih , Mine Çizmecioğlu Jones Filiz

The genetic causes of 46, XY disorders of sex development (DSD) are mostly unknown, having been identified in only 20-35%. Mitogen-activated protein kinase 1, part of the MAPK signaling pathway, which controls testicular development, is one of the etiological genetic pathways. Here, we present a case of 46, XY DSD with heterozygous MAP3K1 variant. A 6-month-old baby was referred to pediatric endocrinology because of ambiguous genitalia. They were born by C-section at 28 weeks ...

Introduction: Pituitary adenomas, while rare in the pediatric population, pose significant challenges in terms of diagnosis and treatment despite their generally benign nature. The aimof this study was to elucidate the clinical features, hormonal profiles, and therapeutic interventions employed in the management of prolactinoma in a pediatric cohort.Methods: This study included children <18 years diagnosed with prolac...

Introduction: Hypophosphatemic rickets is usually due to genetic causes but in rare cases it can develop secondary to MAS, Fanconi syndrome, or oncogenic causes. Oncogenic osteomalacia, also called Tumor-Induced Osteomalacia (TIO), is a rare acquired paraneoplastic syndrome that develops as a result of excessive phosphate loss from renal tubules by FGF23 released from tumour tissue. In addition to the clinical features of rickets, gait disturbances, growth ret...

Keywords: diabetes, MODY, atypicalIntroduction: Type 1 Diabetes (T1D) is the most common cause of diabetes in childhood, but Type 2 Diabetes (T2D) and monogenic diabetes has attracted increasing attention recently. Cases with atypical diabetes may be challenging for diagnosis, treatment and follow-up management. The purpose of this study was to present the characteristics of atypical diabetes cases from a tertiary referr...

Introduction: Prader-Willi Syndrome (PWS) is characterized by severe neonatal hypotonia and feeding difficulty with subsequent hyperphagia, hypogonadism, and short stature. PWS has a prevalence of 1 in 10,000-30,000. Obesity-related complications occur from early childhood onwards. Liraglutide is a glucagon-like peptide-1 (GLP-1) analog that reduces appetite and body weight and improves glycemic control. Scarcity of oxytocin-producing neurons in the hypothalam...

Introduction: The clinical spectrum of nonfunctioning pituitary adenomas (NFPA), which are rare in childhood, varies from asymptomatic to hypopituitarism and/or severe compression-associated symptoms. We present the diagnosis, follow-up, and treatment of pediatric NFPA cases evaluated in a pituitary referral center.Methods: Data of patients aged <18 years and diagnosed with NFPA between 2002 and 2024 were reviewed ret...
