Angioplasty with drug-coated balloon (DCB) is an emerging and reliable method for the treatment of femoro-popliteal lesions. We report our experience with the Stellarex™ DCB in the first 50 patients.

Methods: From July 2015 to November 2017, 50 patients (41 M, 9F), medium age (64 ± 7.4 year) were subject to 33 angioplasties (PTAs) for femoro-popliteal lesions with a paclitaxel-coated balloon (Stellarex™). Based upon clinical data sixteen patients had severe claudication (56% - Rutherford class 3); ten patients suffered from ischemic rest pain (34% - Rutherford class 4); and five presented minor tissue loss (10% - Rutherford class 5). 42% of patients showed femoro-popliteal lesion TASC-II B, and 58% presented lesions pertaining to TASC-II C.

Results: Immediate technical success was 100% without perioperative complications. Primary patency rate was 94% at twelve months. In three cases restenosis (6%) was detected within a year from procedure, and a further PTA DCB was performed with primary assisted patency rates of 100% at twelve months. Two patients underwent major lower limb amputation. Three patients died during follow-up and one patient was lost at follow-up.

Conclusion: DCB angioplasty with Stellarex™ is a viable alternative to traditional endovascular procedures proving satisfactory primary patency rates at twelve months. Based on our experience, treatment with DCB is a first choice technique for non-complex de novo lesions of the femoro - popliteal tract.

According to the 2012 ESPGHAN criteria for diagnosis of celiac disease (CD), duodenal biopsy (DB) can be avoided in children with a clear malabsorption syndrome, anti-tissue transglutaminase IgA (tTG2) ≥ 10x the cut-off, anti-endomysium IgA (EMA) and HLA DQ2/DQ8 genes. The aim of this study is to report our experience and evaluate the accuracy of the actual guidelines.

Patients and methods: This is a retrospective study conducted on all patients diagnosed CD from 2012 to 2018 in our Center. For all patients enrolled were analyzed: data of family history, symptoms, serology, genetics, Marsh grade and follow-up.

Results: A total of 481 children [mean age 6,4 yrs; F:M= 1.8:1] were included in the study. The mean age of patients who were not subject to DB was lower (4.51 yrs) comparing with patients that received DB (6.48 yrs). Out of the 256 patients with anti-tTG2 ≥ 10 fold, 121 underwent DB because of mild symptoms (84/121) or no symptoms (37/121). In all cases Marsh type 3 was found and HLA haplotypes was compatible with CD diagnosis.

Conclusions: Our study confirms that the serology has a primary importance to diagnose CD, regardless of the symptoms. These data suggest that biopsy and HLA haplotypes search, in presence of anti-tTG2 IgA ≥ 10x the cut-off, are wasteful and unhelpful for the patients.

Gastro-oesophageal reflux is common in children, especially in the first year of life, and it may be regarded as physiological. Good functioning of the lower oesophageal sphincter depends largely on the anatomical relationships between oesophagus, stomach and diaphragm hiatus. Relative immaturity of these structures in newborn babies and young children is a risk factor in reflux disease, which may result in a wide variety of typical and/or atypical symptoms and, sometimes, serious complications such as oesophagitis and stenosis. Reflux disease may be diagnosed and studied, basing on morphological and functional aspects and, since the advent of pH-metry, it is possible to personalise the therapeutic approach to children with reflux. Surgical treatment of reflux disease in children has recently been improved due to a mini-invasive surgical approach. Absolute indications are recurrent pneumonia, intractable pain due to oesophagitis and retarded growth, often in association with neurological impairment. In the last three years, 18 children with reflux disease underwent videolaparoscopic surgery in our department, 14 by the Nissen and 4 by the Toupet technique. Post-operative pH-metry always showed a reduction in exposure of the distal oesophagus to acid (integral of H+) and an improvement in oesophageal clearance (short refluxes percentage) indicative of good functioning of the gastro-oesophageal junction. PH-metry proved to be an invaluable technique for planning therapeutic strategy. In follow-up evaluations, it enabled us to monitor functioning of the gastro-oesophageal junction and to avoid other more difficult and invasive tests in patients with severe neurological impairment.
