Gastric outlet obstruction due to an iatrogenic cause in a neonatal period - report of two cases.

Gastric mucosa hyperplasia is a rare cause of upper gastrointestinal obstruction in the neonatal period. One of the etiologic factors of this disorder is prolonged prostaglandin E1 (PGE1) therapy of neonates with congenital cyanotic heart diseases. Continuous PGE1 administration ensures patency of the ductus arteriosus, which is essential for stabilizing the general condition until cardiac surgery can be performed. The clinical symptoms of gastric mucosa foveolar hyperplasia due to long-term PGE1 therapy simulate hypertrophic pyloric stenosis. However, the characteristic ultrasound appearance of both pathologies facilitates determination of the final diagnosis and further treatment. We present two cases of neonates with gastric mucosa and submucosa hyperplasia revealed during ultrasound examination. The results of the ultrasound examination combined with clinical anamnesis allowed diagnosis of gastric mucosa foveolar hyperplasia due to prolonged PGE1 therapy.

Percutaneous coronary intervention triggers a systemic inflammatory response in patients treated for in-stent restenosis -- comparison with stable and unstable angina.

OBJECTIVE AND DESIGN: It is believed that the magnitude of the systemic inflammatory response induced by percutaneous coronary intervention (PCI) impacts on the long-term outcomes in patients with stable angina (SA) and unstable angina (UA). We aimed to determine whether an inflammatory response appears in in-stent restenosis (ISR) patients undergoing balloon angioplasty and to assess its pattern and magnitude in relation to SA and UA subjects. SUBJECTS: 80 patients (59 with SA, 10 with UA, 11 with ISR) were enrolled into the prospective study. TREATMENT: SA and UA patients undergoing single vessel coronary balloon angioplasty followed by stenting versus ISR subjects in whom only balloon angioplasty was performed. METHODS: C-reactive protein (CRP), serum amyloid A (SAA), tumor necrosis factor alpha (TNF-alpha) and interleukin 10 (IL-10) were measured in blood samples collected before and 6, 24 h and 1 month after the procedure. RESULTS: A comparable pattern of inflammatory response in terms of CRP and SAA concentrations in subjects undergoing PCI due to ISR and SA was discovered while in unstable patients its magnitude was substantially higher. CRP and SAA levels increased significantly in each group with the peak value at 24 h and the baseline levels remarkably correlated with the highest markers' concentrations. In contrast, preprocedural TNF-alpha concentrations were higher in ISR group when compared with SA and UA patients. Additionally, in ISR group a twofold increase in their values of borderline significance at 6 h was noted. SA and UA subjects were found to have significantly lower TNF-alpha levels at 6 and 24 h after the intervention though the marker concentrations markedly increased with peak values at 1 month. The levels of IL-10 did not differ at any time point between the groups. CONCLUSIONS: We suggest that PCI triggers a systemic inflammatory response in patients with ISR and considerable differences in its pattern when compared with SA and UA patients were demonstrated. Moreover, a high preprocedural TNF-alpha level and its increase provoked by PCI in the ISR group warrant the need for further investigation of its possible involvement in the restenosis process.

[The closure of persistent ductus arteriosus using coils in a child with Wilm's tumor]. / Zamkniecie droznego przewodu tetniczego za pomoca sprezynki wewnatrznaczyniowej u dziecka z guzem Wilmsa.

In Pediatric Institute of Medical University of Gdansk in all children with neoplasmatic diseases the echo examination is performed, due to exclude coexisting abnormalities of cardiovascular system. During this kind of procedure in 4.5-year-old girl with Wilms tumour the persistent ductus arteriosus was described. Because of the chemotherapy design and its potential cardiotoxicity the closure of PDA using coils was performed immediately. The successful closure of PDA gave the chance to apply the whole therapeutic protocol.

[Recanalization of the ductus arteriosus in a child with non-Hodgkin's lymphoma]. / Rekanalizacja przewodu tetniczego u dziecka z non-Hodgkin lymphoma.

Dissertation describes the case of 7.5-year-old boy with recanalization of the ductus arteriosus. In this patient treated because of the non-Hodgkin lymphoma during the chemotherapy the respiratory failure occurred and mechanical ventilation was required. After the respiratorotherapy in the controlled echocardiography examination the patency of previously closed ductus arteriosus, was described. There was no description of the similar case in available references.
