Aim To determine an outcome of acute kidney injury (AKI) in critically ill children (CIC) who needed renal replacement therapy (RRT) and were admitted to the Paediatric and Neonatal Intensive Care Unit (PICU and NICU) at the Paediatric Clinic, University Clinical Centre Sarajevo (UCCS). Methods The research included 81 children with AKI. The Kidney Disease: Improving Global Outcomes (KDIGO) criteria to define AKI was used. Other laboratory findings and imaging tests were made depending on children's primary disease that led to the AKI. Results Among 81 children with AKI, 38 were girls and 43 boys. A total of 39 (48.1%) patients died; the death was due to the nature of the primary disease and multiple organ failure syndromes. Out of the total of 81 patients the highest mortality rate was found in children in the first year of life, 22 (56.4%), while 17 (43.6%) patients died after the first year of life. Conclusion Without an accurate diagnosis at the right time, due to the lack of adequate biomarkers for AKI screening, the heterogeneity of AKI, comorbidities often lead to unfavourable outcomes of the disease, among CIC, especially in infants with low birth weight and extreme immaturity. Some causes of AKI are preventable and can be reduced by a better organization of primary and secondary health care.

Background: Acute kidney injury (AKI) is the result of various causes and is associated with significant morbidity and mortality as well as long-term renal sequelae in pediatric patients. Objectives: The aim of the study is to determine the causes of AKI in pediatric patients who needed renal replacement therapy (RRT) and were admitted to the Pediatric and Neonatal Intensive Care Unit (PICU and NICU) at the Pediatric Clinic, University Clinical Center Sarajevo (UCCS). Methods: Our research included 81 children with AKI who needed RRT. We used the Kidney Disease: Improving Global Outcomes (KDIGO) criteria to define AKI. Severe acute kidney injury was defined as stage 2 or 3 of AKI when plasma creatinine level ≥2 times the baseline level or urine output <0.5 ml per kilogram of body weight per hour for ≥12 hours. Other laboratory findings and imaging tests were made depending on their primary disease that led to the AKI and its complications. Results: Our research analyzed 81 children with AKI who needed RRT 38 girls and 43 boys ages from birth to 18 years. Mean age of presentation was 6.28 years. Male female ratio in this study was 1.1:1. Non-olyguric AKI was diagnosed in 12 (14.8%) of children with AKI, while the rest 69 (85.2%) had the olyguric type. Patients with AKI were analyzed after a rough division on prerenal in 57 (70.4%) children, intrarenal in 23 (28.4%) and post-renal in 1 (1.2%) patient. Conclusion: As the AKI plays a key role in the mortality and morbidity in pediatric patients, especially in infants, it is important to recognise and treatment on time different etiologies of this serious condition. Some causes of AKI in our country can be prevented by better organization of primary and secondary health care, which would also reduce mortality and morbidity from AKI.

Trauma is the leading cause of pediatric mortality and abdominal injury is a significant contributor to morbidity. Abdominal trauma in the population of injured children, is the third leading cause of death in this population, after head and thoracic injuries. It is the most common cause of death owing to unrecognized injury. They most often occur in traffic accidents, games and sports. The clinical presentation depends on the severity of the injury, the injured organ and the associated injuries. Mesenteric injury from blunt abdominal trauma is uncommon and can be difficult to diagnose. It is known that seatbelt trauma from motor vehicle accidents is the most common mechanism of mesenteric injury and that the mesentery of the small bowel is injured more frequently than that of the colon. We present an unusual case, a seven-year-old boy who was injured while skiing. The patient was in a state of hemorrhagic shock and underwent emergency surgery after an urgent diagnosis. During the operation, the leading trauma and the reason for the hemorrhagic shock were found to be a mesenteric injury, and bleeding from the branches of the superior mesenteric artery. Early transport, monitoring and diagnostics significantly contribute to reducing morbidity and mortality. The standard in surgery is non-operative treatment of injured parenchymal organs. A multidisciplinary approach that includes doctors of various specialties (pediatric surgeons, pediatricians, neurosurgeons, anesthesiologists and radiologists) who contribute to the diagnosis and treatment of injured children through diagnostic and therapeutic procedures has a key role. At the end, the decision regarding surgical treatment is responsibility of pediatric surgeon.

Introduction: Adequate prenatal and postnatal care for preterm neonates not only affects the survival rate, but also the occurrence of chronic diseases, and in the future also affects the quality of life of that children. Aim: To examine the influence of independent predictors (weeks of gestation, body weight, sex) on the outcome of the disease and to analyze the influence of the applied ventilatory mode on the final outcome of treatment. Material and methods:  The study included neonates (n = 248) born prematurely who were treated in the neonatal intensive care unit for a period of one year due to immaturity-related difficulties. Results: The mean age of male neonates (n = 119) at birth was 31.13 ± 3.3 weeks of gestation (WG), and females (n = 129) 31.59 ± 3.2 WG. Weeks of gestation have a statistically significant effect on survival (p = 0.0001), for each more week of gestation, the chances of survival increase by 21%. There was no significant difference between birth weight and sex (p = 0.289), and the birth weight of the neonates had a statistically significant effect on survival (p = 0.0001). For every 10 grams of body weight, in our sample, the chance of survival increases by 2%. Ventilation mode showed a statistically significant effect on neonatal survival (p < 0.05), and intubation mode was used as an indicator. If neonates are switched from non-invasive to invasive ventilation mode, the chance of survival in our sample is reduced by 88%. Conclusion: Weeks of gestation, birth weight, and the use of a noninvasive mode of ventilation are predictors of a positive outcome for preterm neonates.

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.

Abstract Rationale: Circumcision like any other surgical procedure is not devoid of complications. Serious complications are rare and include iatrogenic hypospadias, glans ischemia/necrosis, and glans amputation, all of which require an emergent treatment. Patient concerns: We report here a case of 6 months-old-boy with a superficial glans ischemia following circumcision. Diagnosis: Physical examination revealed a severely cyanotic glans with the moderate edema of the dorsal penile skin. Plasma levels of D-dimer were 8.57 mg/L. Urine passage was unremarkable while color Doppler ultrasonography revealed a normal blood flow. Interventions: The patient was successfully treated with subcutaneous injection of enoxaparin (low-molecular-weight heparin) and topical 2.5% dihydrotestosterone. Outcomes: The appearance of the glans penis on the 5th day was close to normal while the control levels of D-dimer dropped to the reference range. The patient was discharged from the hospital on the 6th day. At 6-month follow-up, the appearance of the glans penis was normal. Lessons: Acute glans penis ischemia following circumcision is a rare complication. Its successful treatment with enoxaparin and topical dihydrotestosterone has not been previously reported in the literature.

The aim of this paper is to report a case of congenital diaphragmatic Bochdalek hernia in eight month old baby with herniation of stomach into thoracic cavity and subsequent postoperative bleeding from right gastroepiploic artery with formation of intraabdominal haemathoma, which was clinically manifested as vomiting and ileus. Multidisciplinary approach (obstetricians, pediatric surgeons and neonatologists) is imperative along with timely diagnosis and treatment.

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.
