Endovascular stenting for chronic femoro-iliac venous obstructive disease: Clinical efficacy and short-term outcomes.

PURPOSE: To report the clinical efficacy and mid-term outcomes of endovascular treatment in patients with chronic, symptomatic, post-thrombotic femoro-iliac venous obstruction. MATERIALS AND METHODS: Forty-two patients with post-thrombotic syndrome (PTS) presenting with femoro-iliac venous obstructive lesions treated in our institution by endovascular approach between March 2012 and October 2017 were retrospectively included. There were 27 women and 15 men with a mean age of 47.3±17 (SD) years (range: 22-86 years). Procedure included first venous recanalization, then pre-dilatation and self-expandable metallic stenting of the narrowed or occluded iliac and/or femoral veins. Severity of PTS and quality of life were assessed at baseline and 3 months after the intervention respectively, using Villalta score and Chronic Venous Insufficiency Questionnaire (CIVIQ-20) scale. Imaging follow-up evaluation of stent patency was based on the results of duplex Doppler ultrasound and computed tomography. RESULTS: Immediate technical success was achieved in 41/42 (97.6%) patients, without any major complications. Primary patency, primary assisted patency and secondary patency at the end of the median imaging follow-up of 18.1 months (IQR, 9.7-34.4) were achieved in 29/42 (66.7%) patients, 33/42 (78.6%) patients and 37/42 (88.1%) patients, respectively. Median Villalta and CIVIQ-20 scores decreased from 14 (IQR, 10-19) and 57 (IQR, 39-72) at baseline, respectively, to 5 (IQR, 2-9) and 30 (IQR, 24-50) 3 months after the procedure, respectively (P<0.0001), showing significant decrease in the severity of PTS and improvement in the quality of life. The multiple linear regression model showed that both baseline Villalta and CIVIQ-20 scores ([95% CI: -7.80-3.79; P<0.0001] and [95% CI: 0.07-0.20; P<0.0001], respectively), age (95% CI: 0.04-0.19; P=0.002) and stenting expanse (95% CI: 0.97-5.65; P=0.006) were independent variables related to Villalta gain. Baseline Villalta (95% CI: 0.89-2.23; P<0.0001) was the single independent variable related to CIVIQ-20 gain. CONCLUSION: This study confirms the high clinical efficacy and favorable mid-term outcomes of endovascular stenting in patients with chronic symptomatic femoro-iliac venous obstructive lesions.

Burden of gastroenteritis outbreaks: specific epidemiology in a cohort of institutions caring for dependent people.

BACKGROUND: In institutions caring for dependent people, viral gastroenteritis occurs frequently and is highly contagious. In elderly persons, these episodes can lead to hospitalization and occasionally death. AIM: To study the impact of gastroenteritis outbreaks (GOs) in institutions caring for dependent people. METHODS: This study was conducted on 18 sites consisting of 35 units from four different disciplines (geriatric medicine and rehabilitation, psychogeriatrics, geriatric nursing homes, and specialized care homes for adults with physical and mental disabilities). Spatio-temporal analysis of GOs was performed during six winter seasons, and clinical and viral data were analysed with regard to structural parameters (size of the sites and dining-room organization), virus epidemiology and chronology of the outbreaks and type of activities. RESULTS: A total of 98 outbreaks were recorded in the 35 units. The risk of GO was high even outside national epidemic periods. Viruses were searched for in 86 outbreaks and were identified in 96.5% (83/86) of these outbreaks: norovirus genotype GII.4 (59.0%, 49/83), other viruses (41.0%, 34/83). There were variations between surveillance periods in terms of GO frequencies and attack rates and types of viruses. Dining-room organization could be a factor in cross-infection at a site. CONCLUSION: Specific surveillance that takes into account the precise epidemiology needs to be developed in institutions caring for dependent people in order to improve infectious disease control and information for healthcare workers.

[Evaluation of hygiene practices during ophthalmologists' consultations in Burgundy, France]. / Evaluation des pratiques professionnelles en matière de gestion du risque infectieux au cabinet d'ophtalmologie en région Bourgogne.

OBJECTIVES: To evaluate the hygiene practices during ophthalmologists'consultations in Burgundy, France, so as to identify the difficulties they encounter in implementing new professional guidelines. METHOD: The survey was based on an anonymous transversal descriptive survey conducted via a questionnaire sent in May 2006 to 102 ophthalmologists. RESULTS: Data from 51 questionnaires were included in the survey, showing a good response rate (50%). The survey revealed that the perception of the risk of transmitting an infection was "important" to "most important" (59.2%). A steam autoclave was used by 38.8% of the ophthalmologists. Those who did not sterilize instruments disinfected them (30%). Finally, ophthalmologists preferred more information to training (90% versus 50%, p=0.015). CONCLUSION: This survey highlights the need for improvements in education for practitioners and their assistants, especially in the sterilization of instruments and equipment.
