The jaundiced newborn: which early monitoring for a safe discharge?

Neonatal jaundice is one of the most common causes of prolonged hospital stay or readmission of a near-term or term baby. Reason of concern at early discharge of a jaundiced newborn is that of bilirubin neurotoxicity, even if a serum bilirubin concentration surely toxic for the brain is still unknown. Kernicterus and severe neonatal hyperbilirubinemia are still problems in the third millennium and the American Academy of Pediatrics claimed the pediatric community to increase vigilance in order to reduce the occurrence of these dramatic events. The only existing kernicterus registry is the pilot USA kernicterus registry whose data on 125 kernicteric term and near term babies from 1992 to 2004 have been recently published. Nobody of the kenicteric babies into the USA register had a serum bilirubin levels below 20 mg/dL. All the babies who suffered from kernicteric sequelae were discharged as healthy from hospital and then, 86% of them, readmitted in the first ten days of life. In the majority of babies (69%) a cause of the severe hyperbilirubinemia was not found. Current knowledge on mechanism of neurological damage induced by bilirubin, unfortunately, does not allow to have a universal evidenced based guideline on how to manage neonatal jaundice. Thus, the existing national guidelines contain inevitable differences in the recommended procedure. Waiting for the future italian guidelines the paper illustrates a proposal of management of neonatal jaundice in term or near term newborns based on available scientific evidence and national guidelines published in english language

Textural and minerochemical features of NWA 1807 and 2180, two new CV3 chondrites from northwest Africa

A textural and minerochemical study has been performed on NWA 1807 and 2180 chondrites in order to determine sizes and typologies of chondrules, relative abundances of mineral phases, compositions of main phases and bulk oxygen isotope composition

A 20-year experience with surgical management of true and false internal carotid artery aneurysms

Aim of the study: The aim of this study was to retrospectively analyse early and late results of surgical management of internal carotid artery (ICA) true and false aneurysms in a single-centre experience. Materials and methods: From January 1988 to December 2011, 50 consecutive interventions for ICA aneurismal disease were performed; interventions were performed for true ICA aneurysm in 19 cases (group 1) and for ICA post-carotid endarterectomy (CEA) pseudo-aneurysm in the remaining 31 (group 2). Early results (<30 days) were evaluated in terms of mortality, stroke and cranial nerves' injury and compared between the two groups with χ2 test. Follow-up results (stroke free-survival, freedom from ICA thrombosis and reintervention) were analysed with Kaplan-Meier curves and compared with log-rank test. Results: All the patients in group 1 had open repair of their ICA aneurysm; in group 2 open repair was performed in 30 cases, while three patients with post-CEA aneurysm without signs of infection had a covered stent placed. There were no perioperative deaths. Two major strokes occurred in group 1 and one major stroke occurred in group 2 (p = 0.1). The rates of postoperative cranial nerve injuries were 10.5% in group 1 and 13% in group 2 (p = 0.8). Median duration of follow-up was 60 months (range 1-276). Estimated 10-year stroke-free survival rates were 64% in group 1 and 37% in group 2 (p = 0.4, log rank 0.5); thrombosis-free survival at 10 years was 66% in group 1 and 34% in group 2 (p = 0.2, log rank 1.2), while the corresponding figures in terms of reintervention-free survival were 68% and 33%, respectively (p = 0.2, log rank 1.8). Conclusions: Surgical treatment of ICA aneurismal disease provided in our experience satisfactory early and long-term results, without significant differences between true and false aneurysms. In carefully selected patients with non-infected false aneurysm, the endovascular option seems to be feasible.© 2012 European Society for Vascular Surgery

Endovascular Treatment of Aorto-iliac Aneurysms: Four-year Results of Iliac Branch Endograft

Introduction: The aim of this report was to analyse early and mid-term outcomes of endovascular treatment (endovascular aneurysm repair, EVAR) for aorto-iliac aneurysms with the use of an iliac branch device (IBD). Report: A total of 85 EVAR procedures with IBD were electively carried out in 81 patients between September 2007 and August 2012. Technical success was obtained in 98.7% of the cases. The mean follow-up duration was 20.4 months (SD ± 15.4). There was one IBD occlusion (1.2%). Estimated 48 months' survival, freedom from re-intervention and branch occlusion were 76.7%, 88.3% and 98%, respectively. Conclusions: EVAR for aorto-iliac aneurysms using IBD is an effective procedure with low complication and re-intervention rates at mid-term follow-up

Alternative hybrid reconstruction for bilateral common and internal iliac artery aneurysms associated with external iliac artery occlusion

Purpose: To describe an alternative reconstruction for bilateral common (CIA) and internal (IIA) iliac artery aneurysms associated with external iliac artery (EIA) occlusion in a patient unfit for open surgery. Case Report: A high-risk 81-year-old man presented with contained rupture of a left CIA aneurysm in the presence of bilateral CIA and IIA aneurysms associated with complete occlusion of the left EIA and normal patency of both common femoral arteries. In an emergent procedure, the left EIA was recanalized subintimally, and the right IIA was embolized with a 14-mm Amplatzer Plug. The main body of a standard Excluder endograft was deployed just distal to the origin of the left renal artery, and the ipsilateral leg was extended into the proximal right EIA. On the contralateral side, a short 10-mm-diameter limb was inserted through a 12-F sheath and deployed in the CIA, proximal to the iliac bifurcation. Via a percutaneous left brachial artery access, 3 covered stents (9359 mm, 10359 mm, 10359 mm) were deployed from the distal IIA to the endograft contralateral limb. A right-to-left femorofemoral crossover bypass graft concluded the operation. The patient was discharged on the 5th postoperative day without complications; follow-up imaging at 6 months showed patency of the stent-graft and crossover bypass, with complete exclusion of the aneurysms and no evidence of endoleak. Conclusion: This case demonstrates an effective solution for complex aortoiliac lesions using commercially available devices, underlining how an accurate knowledge of alternative endovascular techniques and materials is crucial in the management of complex cases
