The total absence of atrial automaticity in a child with sinus node dysfunction
2007
Background A routine sports evaluation identified constant alternation between a junctional and idioventricular rhythm in a 9-year-old child. During exercise testing, electrography demonstrated that the child was in junctional rhythm without any apparent P waves, and had a reduced increase in heart rate. Endocardial atrial pacing captured the atrium and demonstrated that atrioventricular conduction was normal, but the recovery time of the ectopic rhythm was very long. Three-dimensional electrophysiological mapping revealed 1:1 retrograde homogeneous conduction through the right atrium. Investigations Electrocardiography, Holter monitoring, echocardiography, exercise stress testing, atrial p…
Differentiation of benign and malignant lymph nodes in pediatric patients on ferumoxytol-enhanced PET/MRI.
2019
The composition of lymph nodes in pediatric patients is different from that in adults. Most notably, normal lymph nodes in children contain less macrophages. Therefore, previously described biodistributions of iron oxide nanoparticles in benign and malignant lymph nodes of adult patients may not apply to children. The purpose of our study was to evaluate if the iron supplement ferumoxytol improves the differentiation of benign and malignant lymph nodes in pediatric cancer patients on 18F-FDG PET/MRI. Methods: We conducted a prospective clinical trial from May 2015 to December 2018 to investigate the value of ferumoxytol nanoparticles for staging of children with cancer with 18F-FDG PET/MRI.…
Nephroblastoma: does the decrease in tumor volume under preoperative chemotherapy predict the lymph nodes status at surgery?
2011
Background Partial nephrectomy (NSS) for unilateral nephroblastoma may be beneficial, although in case of regional lymph node (LN) involvement, radiotherapy counteracts the functional benefit of NSS. The aim is to verify whether decrease of tumor volume under preoperative chemotherapy implies clearance of regional LN. Procedure SIOP 9301 (1993–2001) collected 1,450 localized nephroblastoma patients of whom 1,360 (93%) had sufficiently available data and were retrospectively reviewed. Results Histologic subtypes were classically distributed. Patients were divided in those with tumor positive LN (76, 5.5%) and those with tumor negative LN (1,284, 94.5%) at surgery. In the LN(+) group, the tum…
Prevalence of patients hospitalised for male breast cancer in France using the French nationwide hospital administrative database
2019
BACKGROUND Breast cancer (BC) in men is a rare and neglected disease representing <1% of all cancers in men and only 1% of all incident BC in western countries. OBJECTIVE This study aimed to describe trends in the prevalence of patients hospitalised for male BC in France from 2009 to 2013, using the national administrative database (PMSI). METHODS We included all men aged ≥18 admitted to hospital for BC during this period and estimated the prevalence of male breast cancer hospitalised in France over 5 years. We also describe clinical characteristics and treatments in men with surgery for BC over the 5-year period of the study. RESULTS The prevalence of patients hospitalised for BC significa…
Recurrence of esophageal cancer after R0 surgery: risk factors and evolution
2013
Introduction despite advances in surgical and adjuvant therapy, recurrence in esophageal cancer submitted to R0 surgery remains high. The aim is to define risk factors and recurrence patterns. Additionally, to show the management carried out and the outcome of patients showing recurrence. Material and methods observational and prospective study that included 61 patients. Neoadjuvancy therapy was indicated on T3, T4 and N+ tumors and every lymph node dissection was performed in two fields. Recurrence is defined at distance, regional or local, when, recurrence is detected after six months. According to clinical features and the recurrences, a palliative, chemotherapeutic or surgical managemen…
Positron Emission Tomography for Staging Esophageal Cancer: Does It Lead to a Different Therapeutic Approach?
2003
Accurate preoperative staging is essential for the indication and selection of the appropriate surgical procedure in patients with esophageal cancer. The present prospective study was designed to determine if the preoperative use of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) increases the accuracy of staging esophageal cancer compared with computed tomography (CT) and if it thereby leads to a different therapeutic approach. A total of 58 patients, 46 men and 12 women (mean age 61 years), with histologic proof of esophageal carcinoma underwent FDG-PET of the neck, chest, and abdomen, as well as CT of the chest and abdomen, to determine tumor stage. FDG-PET and CT data we…
Robot-assisted minimally invasive esophagectomy (RAMIE) compared to conventional minimally invasive esophagectomy (MIE) for esophageal cancer: a prop…
2020
SUMMARY Robot-assisted minimally invasive esophagectomy (RAMIE) is increasingly being applied as treatment for esophageal cancer. In this study, the results of 50 RAMIE procedures were compared with 50 conventional minimally invasive esophagectomy (MIE) operations, which had been the standard treatment for esophageal cancer prior to the robotic era. Between April 2016 and March 2018, data of 100 consecutive patients with esophageal carcinoma undergoing modified Ivor Lewis esophagectomy were prospectively collected. All operations were performed by the same surgeon using an identical intrathoracic anastomotic reconstruction technique with the same perioperative management and pain control re…
The SIC-GIRCG 2013 Consensus Conference on Gastric Cancer.
2014
Abstract The topic chosen by the Board of the Italian Society of Surgery for the 2013 annual Consensus Conference was gastric cancer. With this purpose, under the direction of 2 chairmen, 36 experts nominated by the Regional Societies of Surgery and by the Italian Research Group for Gastric Cancer (GIRCG) participated in an experts consensus exercise, preceded by a questionnaire and mainly held by telematic vote, in accordance with the rules of the Delphi method. The results of this Consensus Conference, presented to the 115th National Congress of the Italian Society of Surgery, and approved in plenary session, are reported in the present paper.
ITPA deficiency and ribavirin level are still predictive of anaemia in HCV–HIV-coinfected patients receiving ribavirin combined with a first-generati…
2017
Background We aimed to determine the impact of inosine triphosphatase (ITPA) deficiency on ribavirin (RBV)-induced anaemia in HIV–HCV-coinfected patients receiving a triple therapy including the haematotoxic direct-acting antiviral agent boceprevir (BOC). Methods Patients of the ANRS HC27 BocepreVIH study were genotyped for two ITPA single nucleotide polymorphisms involved in ITPA deficiency. RBV trough concentration (Ctrough) was determined at week (W)4 and W8. Impact of ITPA deficiency on anaemia, RBV Ctrough, response and haematotoxicity (grade 3/4 anaemia, erythropoietin [EPO] use, RBV dose reduction or transfusion between day [D]0 and W8) was evaluated. Impact of RBV Ctrough on anaemia…
Aneurysms of the coronary arteries in infants and children. A review, and report of six cases.
1977
In recent years large numbers of the so-called “mucocutaneous lymph node syndrome” or “Kawasaki's disease” have been described by Japanese workers, but instances of this disorder are only now being reported as isolated cases by European or North American physicians. The disease has, therefore, been considered to be a new entity. One of its most striking features is the development of aneurysms of the coronary arteries in infants or children, which may lead to sudden death. Aneurysms of the coronary arteries in childhood are rare, and hence it was considered relevant to report six such cases, and to examine their possible relationship to Kawasaki's disease. The pathological changes underlyin…
