A total of 25 boys and 20 girls aged 5-17 years with type I diabetes mellitus and disease durations of 2-10 years were studied. All had diabetic polyneuropathy. The microcirculation was studied by laser Doppler flowmetry. Treatment consisted of using a running impulse magnetic field. This method was found to be effective in diabetic polyneuropathy with the running field along the limb towards the periphery at a run velocity (field modulation frequency) being a multiple of the nerve fiber spike conduction velocity.

Childhood obesity is an urgent problem of pediatric endocrinology due to the widespread occurrence, the development of metabolic complications and their steady tracking into adulthood. The developed clinical guidelines are the main working tool of the practitioner. They briefly and structurally present the main information about the epidemiology and modern classification of obesity, methods of its diagnosis and treatment based on the principles of evidence-based medicine.

Objective:We report a male patient with ovotesticular disorder of sex development (OTDSD), resulting from structurally abnormal Y chromosome. Case report: A 3-year-old boy was admitted to the Surgical Pediatric Department for masculinizing reconstruction. He had a clitorophallus, bifi d scrotum, perineal hypospadias and bilateral impalpable gonads. Pelvic ultrasound and laparoscopy showed a uterus and two gonads with primary ovarian follicles. Chromosome analysis detected a mos 47,XX,mar/46,XX karyotype. Complex genetic evaluation revealed that the marker was Yp isochromosome. Surgical care included a feminizing genitoplasty and separation of the gonads with total excision of testicular tissue. Conclusions: The presented case emphasizes the importance of a systematic approach to the investigation and management of the patients with ovotesticular DSD. It also raises the important issue about gender reassignment in intersex individuals in mid-childhood.

Serum pseudocholinesterase activity in pregnant women was assayed spectrophotometrically using either propionylthiocholine or suxamethonium as substrate. All patients had a normal phenotype as indicated by normal dibucaine and fluoride numbers. However, the mean cholinesterase activity was lower than in the general population. There was a negative correlation between cholinesterase activity and the duration of neuromuscular blockade following suxamethonium, but no correlation was observed between the cholinesterase activity and the duration of block following atracurium.
