Introduction: Neural tube defects (NTDs) are multifactorial congenital anomalies of the central nervous system that results from failed neural tube closure between the 3rd and 4th weeks of embryonic development. Numerous clinical and experimental studies indicate that supplementation with folic acid before and during early pregnancy reduces the development of these anomalies. The present study examined the incidence and risk factors for NTDs and evaluated the effects of folic acid supplementation.Methods: This cross-sectional study included all children with NTDs who were hospitalized at the Pediatric Clinic, Clinical Centre University of Sarajevo during the period from January 01, 2008 to December 31, 2012. Data were collected retrospectively from the medical histories of hospitalized children. The study included children in pediatric clinics from four cantons (Sarajevo, Zenica–Doboj, Unsko–Sanski, and Central Bosnia) of the Federation of Bosnia and Herzegovina. The number of live births for the specified period in each of the four cantons was taken from a report by the Cantonal Ministry of Health.Results: Among the 69,096 live births recorded during the study period, 39 children had verified NTDs, with an overall incidence of 0.56:1,000 (or 5.6:10,000) in all four cantons. The most common NTDs were myelomeningocele with hydrocephalus (22/39, 56.4%), followed by isolated myelomeningocele (9/39, 23.1%), spina bifida occulta (7/39, 17.9%), and occipitocele (1/39, 2.6%). A total of 33.3% (13/39) of mothers took folic acid, but only one began supplementation prior to pregnancy, while 67.7% (26/39) of mothers did not take folic acid during pregnancy. NTDs were found more frequently in primiparas (53.8%), women with low education (basic school, 64.1%), and unemployed women (82.1%).Conclusion: It is important to make national recommendations for folic acid supplementation for women of reproductive age, but also change the public health policy that includes mandatory fortification of basic foods as this is the best measure for primary prevention of NTDs in the whole population regardless of employment and education status. Additional comprehensive studies are required to assess the incidence and risk factors throughout Bosnia and Herzegovina.

Abstract Rationale: Pheochromocytoma (PHEO) is a rare neuroendocrine tumor arising from chromaffin cells of the adrenal medulla. Most pediatric PHEOs are functional tumors, and clinical manifestations are related to catecholamine hypersecretion and/or tumor mass effects. Patient concerns: We report here a case of a 10-year-old boy with a highly functional adrenal PHEO detected after the evaluation of a generalized tonic-clonic seizure in the patient. His vital signs at admission were: blood pressure up to 220/135 mm Hg; pulse, 112 beats/min; temperature, 37.4°C; respiratory rate, 22 breaths/min. Diagnosis: A 24-hour urine collection for catecholamines test showed a marked increase in Vanillylmandelic acid levels (338.9 μmol/L). An abdominal magnetic resonance imaging revealed a well-defined left adrenal gland mass measuring ∼5 cm in its largest dimension. Interventions: The mass was surgically removed, and histopathological examination revealed PHEO with low malignant potential (Adrenal Gland Scaled Score/PASS/ < 4). Outcomes: The patient was discharged on the 10th postoperative day in good condition. At 24-month follow-up, the patient was doing well without complications such as tumor recurrence, elevated blood pressure, and seizure. Lessons: PHEO should be considered in the differential diagnosis of children with seizures presenting in the emergency department. A multidisciplinary approach to the evaluation and treatment of PHEO is also crucial for a successful outcome.

This study aimed to show the spontaneous rupture of the stomach in a 3-year-old girl. The patient was admitted to the pediatric clinic due to poor general condition that occurred suddenly with severe abdominal pain, vomiting, and the development of hypovolemic shock (blood pressure was unmeasurable, in acidosis), and after the ultrasound and abdominal X-ray, she was operated by the pediatric surgeon within 6 h of admission. During surgery, multiple defects of stomach mucosa with transmural bleeding without pathohistological changes in the muscle layer were found in the large stomach blood vessels. Treatment was continued in the pediatric intensive care unit with the development of life-limiting complications: peritonitis, sepsis, intracranial hemorrhage, and outcome of death. Rupture of the stomach caused by acute distension is rarely seen outside the neonatal period with fast clinical course and high mortality rate. Early diagnosis and rapid surgical procedures are a prerequisite to avoid the development of life-limiting complications that lead to a fatal outcome.

Introduction: Plasmapheresis also known as a therapeutic plasma exchange (TPE) is extracorporeal procedure by which individual components of plasma that are harmful or blood cells can be removed from organism by using a blood separation technology. Aim: To present the results of the implementation of plasmapheresis in children in the Department of Pediatric Intensive Care of Pediatric Clinic, Clinical center of Sarajevo University, Bosnia and Herzegovina. Patients and methods: Research (period from December 2011 to June 2016) analyzed 66 plasmapheresis (11 patients–6 plasmapheresis per patient). Results: Out of 11 patients, 7 (63.6%) were girls and 4 (36.4%) were boys. The average age of patients was 11.6 ± 3.9 years (the youngest patient had 4 years and 7 months, while the oldest had 16 years and 10 months). Plasmapheresis were significantly more often done in the winter and summer. Underlying disease was in 54.5% of cases of neurological origin. The treatment was in form of receiving IVIG in 7 patients, or the application of mechanical ventilation in 6 patients. The most common complication was hypotension, which occurred in 45.5% of patients, followed by bleeding in 36.3%, hypercoagulability in 27.2% of patients and hematoma in 27.2% of patients. Lethal outcome occurred in 3 (27.2%) patients. Conclusion: Plasmapheresis represents an invasive method due to need for placement of centralized venous catheter that provides adequate blood flow during the procedure. Although complications can be serious, they are rare and are mainly related to the presence of central venous catheter, hemostasis disorders due to use of anticoagulant therapy, and hypotension of the cardiovascular system. It should be noted that for success of plasmapheresis in children multidisciplinary approach is necessary (children’s nephrologist, neuropediatrician, intensive care doctor) as well as well-trained team of doctors and nurses with the acquired knowledge and skills.

Introduction: Developmental hip dysplasia represents the most common deformation of locomotor system in children. Developmental modulation of the hip is expressed during first year of life which is important for early diagnosis and treatment. Therefore, in the practice, it is very important to set a diagnosis early with application of simple and convenient methods (ultrasound) in order to achieve fast and efficient therapeutical effect and avoid permanent disability. Aim: The aim of this paper is to point out the increase of prematurely born infants and their survival thanks to the development of Unit for Intensive Neonatal Care at the Pediatric Clinics in Sarajevo. Material and methods: Clinical investigation included 150 infants (77 girls and 73 boys) in whom the developmental hip dysplasia was diagnosed with clinical exam, ultrasound exam and x-ray of the hips. The exams were done in period of January 2012 to August 2014. Results: Two groups of patients were formed. The first one consisted of premature infants, total number of 75 (34 girls and 41 boys), with developmental hip dysplasia that was diagnosed at the first exam at the Ultrasound unit of the Pediatric clinics and at the Intensive Neonatal Care Unit of the Pediatric Clinics in Sarajevo. Second (control) group consistsed of patients-on term infants who had diagnosed one of developmental hip dysplasia, total of 75 (43 girls and 32 boys) during first exam in the Ultrasound unit of the Pediatric clinics in Sarajevo. Conclusion: The frequency of premature birth is between 5 and 10% of all labors and demonstrates increasing trend. We suggest ultrasound examination of hips in each newborn, term or premature, at the age of 6 weeks after birth.

Introduction: Application of a central venous catheter (CVC), as a temporary or permanent vascular access for hemodialysis, has been continuous practice at the Sarajevo Pediatric Clinic, Department of Pediatric Intensive Care. The main goal of the article is to present our experiences with central venous catheters in the treatment of these patients. Material and methods: In the period from January 2009 to December 2014 a total of 41 patients were treated and a total of 56 catheters were placed. Results: The results show the prevalence of the femoral venous catheter (69,64%), with significantly smaller participation of jugular (28,57%) and symbolic participation of subclavian catheters (1,78%). Frequency of infections of 8,92% in our article is lower than the percentage contained in the data of the National Nosocomial Infections Surveillance System, which provided data related to 17% of catheter related infections. The most common agents of the catheter related infections in our patients are gram-negative bacteria from the Klebsiella pneumoniae group. Conclusion: The issue of the higher complication percentage during the treatment is linked with hemostasis related to bleeding into or around the catheters in 28,57% of patients, and to clotting disorder in terms of thrombosis in 10,71% of patients.

Antenatal corticosteroids given to women, who are 24 to 34 weeks pregnant and may deliver within the next 24 hours to 7 days, are associated with significant reduction in rates of respiratory distress syndrome, intraventricular hemorrhage and mortality of pre-term babies. The aim of this study is assessment of antenatal corticosteroid effectiveness in reduction of RDS incidence in optimal delivery-treatment interval, in comparison to babies delivered before and after the optimal treatment interval has elapsed. This investigation included 80 pre-term babies between 26 and 34 gestational weeks whose mothers received corticosteroids before delivery. Control group consisted of 92 children of the same gestational age, whose mothers did not received corticosteroids antenatally. Babies of diabetic mothers, babies with IUGR and babies with congenital abnormalities were excluded. RDS was significantly less frequent in babies antenatally treated by corticosteroids (x2 31,473 p < 0.0001 coefficient contingency 0.366) then in babies whose mothers did not received corticosteroids before delivery. The majority of babies, 54.67% (p < 0.01) were born in optimal interval, 24 hours to 7 days from the beginning of the treatment, 32.0% (24/75) children were born within 24 hours and 13.3% (10/75) were born more then 7 days after the start of treatment. Comparing the incidence of RDS between groups of children born in optimal treatment-delivery interval (1 -7 days) and in the group of children born within 24 hours or after 7 days from the beginning of the treatment, no significant difference was found. The effect was clinically comparable, which suggests the possibility of reduction treatment-delivery interval in acute clinical conditions.
