Epidemiology of Childhood Fractures in Bulgaria: A Retrospective Survey

Boyadzhiev Veselin , Iotova Violeta , Varbanova Boryana

Objectives: The results from several European studies done during the last 25 years show that fractures are common in childhood with the highest incidence in pubertal years. Fractures are more prevalent among males, and the distal arm is the most common location. The role of the body weight as a risk factor for fractures in childhood is still unclear and under debate.Methods: А survey about fracture history and the p...

Boyadzhiev Martin , Boyadzhiev Veselin , Marinov Luchezar , Iotova Violeta

Background: We present a 3 years old boy born on term from young non-consanguineous parents with negative family history. Shortly after birth swelling of the feet and multiple generalised erythematous cutaneous plaques and nodules gradually appeared. Recurrent fever attacks, hepatosplenomegaly, significant growth delay (height – 4.0 S.D.) and progressive loss of subcutaneus fat tissue followed.Objective and hypotheses: Laboratory inve...

Boyadzhiev Veselin , Bliznakova Dimitrichka , Iotova Violeta , Schlingmann Karl

Background: Hypercalcemia requires new investigation pathways after publishing the mutations of the CYP24A1 gene. Furthermore, diagnostic puzzles connected to it still remain.Objective and hypotheses: We present a 1.5-years-old girl with infantile hypercalciuria who has been followed-up since she was 4 months old. The child is born from uneventful pregnancy, normal delivery, on term with weight 3600 g and length 52 cm. Two months after birth she became i...

Rankova Kamelia , Galcheva Sonya , Mladenov Vilchelm , Boyadzhiev Veselin , Bocheva Yana , Yordanova Nikolinka , Bazdarska Yulia , Iotova Violeta

Growth hormone (GH) has been used for the treatment of short stature due to GH deficiency (GHD) for over 60 years. Height velocity (HV) in the first year of therapy is well studied and its crucial importance for growth outcome in subsequent years is confirmed.Objectives: The aim of this study is to assess the responsiveness to GH treatment in GHD patients of a newly established treatment center before and after change in starting GH dose...

Yordanova Nikolinka , Iotova Violeta , Galcheva Sonya , Bazdarska Yuliya , Mladenov Vilhelm , Boyadzhiev Veselin

Prader-Willi syndrome (PWS) is a genetic condition (frequency from 1:8000 up to 1:30 000), which is associated with deletions of chromosome 15 (region 15q11.2), maternal uniparental disomy and impring defects. It is characterized by muscle hypotonia in the early postnatal period, excessive weight gain after 2 years of age, lack of satiety, short stature, hypogonadism and compulsive-like behavior. Every patient has his/her own specific needs that change with age and individuali...

Introduction: Premature ovarian failure (POF) is defined as a heterogeneous disease leading to amenorrhea and ovarian failure before the age of 40 years. It is found in 1-3% of women of reproductive age, with some negative consequences such as cardiovascular disease, osteoporosis and sexual dysfunction. Triple X syndrome is characterized by POF with primary or secondary amenorrhea, tall stature, large feet. Girls with triple X syndrome show accelerated growth ...

Background: Evidence associates obesity with glomerular hyperperfusion. Concurrent inflammation, hypertension, dyslipidemia, and insulin resistance represent further established risks to renal health in both children and adults.Objective and hypotheses: To investigate the relationship between childhood obesity and risk of renal impairment.Method: A total of 114 (38.6% boys) obese according to the IOTF reference but otherwise health...

Rankova Kamelia , Iotova Violeta , Bocheva Yana , Shefket Sevim , Yordanova Nikolinka , Bazdarska Yuliya , Tsochev Kaloyan , Galcheva Sonya , Boyadzhiev Veselin ,

Acid-labile subunit (ALS) is a glycoprotein, which is produced in the liver in response to growth hormone (GH). The main role of ALS is to form a complex with insulin-like growth factor I (IGF-I) and IGF binding protein-3 (IGFBP-3) in order to extend their circulating half-life and thus support the action of GH. Although the mechanism and the consequences of ALS deficiency are well studied, ALS-deficient patients are still of research interest because of the unclear incidence ...
