Transient neonatal diabetes mellitus (TNDM) occurs in 50-60% of all cases of neonatal diabetes mellitus (NDM). The most common cause of TNDM (70%) is almost invariably associated with defect in chromosome 6 and mutations in the KCNJ11, ABCC8, INS, NHF1B etc. genes. TNDM is caused by mutations in the GATA6 gene in rare cases. This gene encodes a transcription factor that is important for the development of the hematopoietic, cardiac and gastrointestinal systems.<p class="ab...

Introduction: Type 1 diabetes mellitus (T1D) is the most common form of carbohydrate metabolism disorder in childhood. There are also monogenic forms of diabetes. In the world literature, there are isolated mentions of the combination of monogenic and autoimmune forms of diabetes mellitus.Clinical case: A 10-year-old obese patient presented with hyperglycemia. At hospitalization: height 168 cm, weight 87 kg, SDS BMI +3.0. Glycemia 14.4 m...

Mutations in HNF1A gene underlie the development of maturity onset diabetes of the young type 3 (MODY3). Mutations in ABCC8 gene are the cause of neonatal DM and the rare MODY12, which is clinically similar to MODY3. In these forms of MODY, there is a high sensitivity to sulfonylurea. Patient A, 17 y.o. He was born to woman with gestational DM. At the age of 12.5, fasting hyperglycemia of 13 mmol/l was detected. Insulin therapy was not prescribed due to the parent’s refu...

Background: Maturity-onset diabetes of the young (MODY) is a heterogeneous group of disorders characterised by autosomal dominant type of inheritance and caused by genetic defects leading to dysfunction of pancreatic beta-cells. At least 13 types of MODY have been described in the literature, the most frequent of which are MODY types 1–3. The frequency of different MODY types in children in Russia has not been studied before.<strong...

Background: Papillary thyroid cancer has been described in three patients with Turner syndrome (TS) who received growth hormone therapy (Cabanas P, 2005; Bautembach-Minkowska J, 2018). We are presenting a case of papillary thyroid cancer in a girl with a late-diagnosed Turner syndrome who has not received any hormonal therapy up to 17 years.Clinical case: A girl was diagnosed with TS syndrome (karyotype 45XO/46X i(X)q) a...

Introduction: Two-stage surgical feminization is a part of the multidisciplinary rehabilitation of girls with external genital virilization. The first stage involves clitoroplasty and labioplasty with preservation of urogenital sinus (US) in girls with third degree of virilization according to Prader classification and higher. US eliminating is performed by second stage in the puberty. Persistence US may cause dysfunction of urodynamics and infections of the l...

Introduction: To date, there are no clear indications for surgical treatment of nodular goiter in children. Current scheme of diagnostic evaluation thyroid nodules in children is not always justified. A number of patients either go to the removal of thyroid remnants when a carcinoma is found in the histological examination and the need for radioiodine therapy, or are at risk of surgery if the results of the final histology show that the disease is benign.<p class="abstext"...

Introduction: Female hypospadias (FH) is one of disorders of sex development signs (DSD). Short and wide urethra that opens into the vagina predisposes to occurrence of recurrent infection of urinary tract, vaginal voiding and postoperative narrowing of artificial vaginal introitus (AVI).Aim: Improve the results of correction FH with stenosis AVI using reintroitoplasty separating the urinary and genital tracts in patients with DSD....

Background: Congenital hypopituitarism (CH) in the neonate which manifests as the deficiency of one or more pituitary hormones can be presented by a highly variable phenotype. Either as isolated hypopituitarism or with associated developmental defects such as ocular, midline, and genital abnormalities. Mutations in genes encoding for a number of transcription factors have been described in a minority of patients with CH. This indicats that further genes remain to be identified...

Introduction: Thyroid surgery in children is associated with high risk of recurrent laryngeal nerves (RLN) damage. It is due to complex and variable anatomy, high bleeding which decreasing visualization and requiring instrumental hemostasis. Large goiters change of syntopy, metastatic process requires bigger aggression and volume of intervention. The risk of damage significantly increases during repeated operations due to the scar process. There is significant...
