Aim: The aim of this study was to analyze risk factors and outcome of neonatal pneumothorax in Tuzla Canton. Methods: Neonates with chest X-ray confirmed pneumothorax in University Clinical Center of Tuzla, within a three-year period, from January 2015 to December 2017, were retrospectively studied. Participants were evaluated for baseline characteristics, predisposing factors of neonatal pneumothorax, accompanying disorders and mortality. Results: During the observed three-year period 11425 neonates were born in Tuzla Canton, with 7.33 % of preterm births, and 604 neonates were treated in NICU, with 265 neonates who required mechanical ventilation. Neonatal pneumothorax (NP) was diagnosed in 22 patients (9 term, 13 preterm), 12 (54.5%) were male. The incidence was 0.20% of total births, respectively 3.64% of those treated in NICU. The mean gestational age were 35.1 ± 3.0 weeks and birth weight 2 506.8 ± 727.7 grams. NP was mostly unilateral (72.7%) and right-sided. The most commonly associated diseases were: respiratory distress syndrome, intracranial haemorrhage, pneumonia, transient tachypnea and sepsis. In 8 (36.4%) neonates, the underlying cause of NP could be mechanical ventilation (secondary), whereas in 14 (63.6%) NP was spontaneous, without previous mechanical ventilation, although 11 of them required mechanical ventilation after pneumothorax. Conclusion: All perinatal risk factors were investigate, and significant differences in two observed groups related to mechanical ventilation were found for birth weight, gestational age, Caesarean section, length of mechanical ventilation, surfactant replacement therapy and outcome. Three (13.64%) neonates with NP died, and among risk factors with poor outcome, significant was only Apgar score in the first minute ≤ 5.

Sarcomas of the female genital tract in general are rare and ovarian sarcomas comprise less than 1% of ovarian malignancies. In the literature there are 15 reported angiosarcomas of patients 21 year old and younger with no one originated in the ovary. We report a case of ovarian angiosarcoma in an 11 year old girl, presented with left side hip pain. MRI of abdomen and pelvis confirmed expansive solid and cystic mass occupied both ovaries. Imunohistochemistry staining was performed, CD34, Factor VIII, CD31, in order to confirm the diagnosis. Final diagnosis was angiosarcoma. The patient received 6 cycles of chemotherapy, according to the CWS-2002P protocol. 8 months after the diagnosis was established, there were no signs of any tumors according to the ultrasound, CT scan, and MRI. Although, extremely rare, angiosarcoma can also affect children and this diagnosis should be considered carefully in tumor with rich vascular network, necrosis and brisk mitotic activity.

The canal of Nuck is analogous to a patent processus vaginalis in a male, which normally loses its communication to the peritoneal cavity within the first year of life. Failure of obliteration of this tract can result in a hydrocele. We present a rare case of a 2-year-old girl with left-sided groin swelling, diagnosed as inguinal hernia. Patient underwent surgical exploration and establishes definitive diagnosis as cyst of the canal of Nuck.

<p><strong>Background:</strong> Many efforts have been made to find diagnostic tools that would help select children with clinical signs of acute appendicitis that would need immediate appendectomy and to find tools that would reduce the numbers of negative appendectomies.</p><p><strong>Aim:</strong> We aimed to show the association between leukocyte count, level of C-reactive protein and interleukin-6 in peripheral blood on the one side and the degree of histological findings on appendix after appendectomy on the other side in children with high clinical probability for appendicitis (Alvarado score&gt;7).</p><p><strong>Methods:</strong> We analyzed 80 patients of both genders, younger than 15 years, with Alvarado score&gt;7, which underwent open appendectomy with subsequent histological analysis of removed appendices. We sampled 20 consecutive cases without signs of inflammation (group I), 20 cases with pathological signs of incipient inflammation (group II), 20 cases with signs of phlegmonous inflammation (group III) and 20 cases with signs of perforated appendix (group IV). Prior to appendectomy, a peripheral blood was sampled and sent for analysis of leukocyte count and C-reactive protein and interleukine-6 level. We compared values of all 3 measured parameters according to histological findings; we also used Receiver Operating Characteristics (ROC) analysis in order to evaluate diagnostic thresholds for detecting the histological signs of appendicitis.<strong> </strong></p><p><strong>Results:</strong> The lowest values of all observed parameters were found in group of negative appendicitis while highest were observed in the group of perforated appendicitis. We have observed a significant between group differences in values of all three parameters according to the degree of histological inflammation (p&lt;0.001). ROC analysis demonstrated that interleukine-6 had the best diagnostic performance in detecting patients with histological signs of appendicitis (AUROC=0.99; 95% CI=0.99-1.00) when compared to CRP and leukocyte count (p&lt;0.05). There was no significant difference in diagnostic performance between CRP and leukocytes counts (p=0.35).</p><p><strong>Conclusion:</strong> Leukocyte count, CRP and interleukine-6 are very useful markers which may help in diagnostics and differentiation of phlegmonous and perforated appendicitis. In patients with high probability of appendicitis, measurement of interleukine-6 may help in better patient selection.</p>
