Objective: To evaluate the prevalence of strabismus in premature children after the screening for retinopathy of prematurity (ROP) and to determine whether the level of prematurity (birth weight and gestation age) can be used as a predictor for both strabismus development and disease activity. Methods: This is a retrospective study, conducted in the Clinic for Eye Disease, section for Pediatric Ophthalmology of the Clinical Centre University of Sarajevo during the period from December 2013 until January 2017. 126 patients were involved. The inclusion criteria were gestational age ≤ 34 weeks, birthweight ≤ 2000 g and performed screening test for ROP. Patients were divided into three groups: patients without ROP, patients with spontaneous regression and patients with active ROP. Results: 52.4% patients were suffering from strabismus (30.2% esotropia, 22.2% exotropia). All the patients with active ROP had esotropia (60.0%). The average birth weight and gestational age were lower in patients with strabismus (1371.3 ± 58.0 g and 29.7 ± 0.4 weeks respectively). Conclusion: Lower gestational age and birth weight of premature children showed the increased probability of strabismus development especially esotropia. Prematurity level was significantly lower in patients with active ROP compared to the rest of the patients.

The acute scrotum (AS) in the pediatric population is a medical emergency. AS is usually caused by testicular torsion (TT) and torsion of the appendix testis (TAT). The current study explored which demographic and clinical characteristics can help distinguish between TT and TAT. We analyzed all children ≤16 years who underwent surgical exploration for AS. The patients were divided into Group 1/TT and Group 2/TAT. Ninety patients were included in the study (24 with TT and 66 with TAT). The peak incidence of TT was significantly higher than in the TAT group (p<0.001). Scrotal pain was more prevalent in the TAT group (p=0.02), whereas systemic signs (nausea/vomiting and abdominal pain) affected more frequently the TT patients (p=0.003 and p<0.001, respectively). The duration of symptoms was significantly longer in the TAT group (p<0.001). The duration of symptoms in the TT cohort significantly impacted the testicular salvage (p=0.008). Color Doppler ultrasound (CDUS) findings of absent/decreased testicular blood flow in the affected testis strongly favored the diagnosis of TT (p<0.001). The older age, shorter duration of symptoms, systemic signs, and CDUS findings can help distinguish between the two most common acute scrotum causes.

Purpose The acute scrotum (AS) in the pediatric population is a medical emergency. The most common causes of AS include testicular torsion (TT) and torsion of the appendix testis (TAT). Their distinction may be clinically challenging. The purpose of our study was to compare demographic and clinical characteristics of the pediatric cases of TT and TAT and thus provide clinical evidence for distinguishing these two conditions. Methods We retrospectively analyzed all children ≤ 16 years who underwent surgical exploration for AS. The patients were divided into Group 1 or TT and Group 2 or TAT groups. Results Ninety patients were included in the study (24 with TT and 66 with TAT). Patients with TT were significantly older than those with TAT (p < 0.001). The peak incidence of TT was in the age of 12–16 years (p < 0.001), whereas the peak of TAT was in the age group of 7–11 years (p < 0.001). Scrotal pain was more prevalent in patients with TAT (p = 0.02), whereas systemic signs (nausea/vomiting and abdominal pain) affected more frequently the TT patients (p = 0.003 and p < 0.001, respectively). The mean duration of symptoms was significantly longer in the TAT group than in the TT group (p < 0.001). Color-Doppler Ultrasound (CDUS) findings of absent or decreased testicular blood flow in the affected testis strongly favored the diagnosis of TT (p < 0.001). Conclusion Our data indicate that the older age, shorter duration of symptoms, systemic signs (nausea/vomiting and abdominal pain), and characteristics CDUS findings can help distinguish between the two most common acute scrotum causes.

INTRODUCTION Gastric acidity plays an important role in the protection of infants against various pathogens from the environment. The histamine-2 receptor blockers (H2-blockers) are off-labeled drugs that are frequently prescribed in preterm neonates to prevent stress ulcers. The impact of the H2-blockers on the development of the necrotizing enterocolitis (NEC) in preterm infants is still controversial, particularly in the developing world. MATERIALS AND METHODS One hundred twenty-two preterm infants were enrolled in the study. The multivariate logistic regression model was used to identify potential postnatal risk factors associated with NEC. RESULTS Preterm infants (n = 51) with total NEC, medical NEC, and surgical NEC had the highest rate of receiving ranitidine compared with controls (n = 71) (39.2%, 19.6%, and 47.6%, p < 0.05). Logistic regression analysis revealed that ranitidine use and nosocomial infections were significantly associated with NEC development (odds ratios 1.55 and 3.3). CONCLUSIONS We confirm that ranitidine administration was associated with an increased risk of NEC in preterm infants. H2-blockers use should be only administered in very strictly selected cases after careful consideration of the risk-benefit ratio.

Throughout history, built environment developed intuitively on empirical experience led by trial and error. Such approach provided resilience and evolvement of patterns that guided spatial organization. Newer interventions in the rural environment resulted in disconnected spatial fragments. By comparing vernacular and contemporary planning and construction practice in the natural park Blidinje, the authors tried to identify the reason for which contemporary interventions resulted in new patterns in spatial planning, ones completely unfamiliar for this geographical area. They identified the reason in the fact that men started to treat the natural space as a commodity, forcing stakeholders to be led primarily by economic principles. Such principles are rigid and linear, instead of contextual in this matter. At the same time, the environmentally sound approach should respect complexity of whole endeavor aiming to achieve diversity and variability. The models developed based on complexity theory and self-organization should preserve continuity and integrity of the place and man.
