RESUMO
PURPOSE: To investigate an examiner-independent catheter venography protocol that could be used to reliably diagnose venous outflow abnormalities in patients with multiple sclerosis (MS) and chronic cerebrospinal venous insufficiency and to determine whether venous angioplasty is effective in the treatment of these abnormalities. MATERIALS AND METHODS: A total of 313 patients with MS and 12 patients with end-stage renal disease underwent echo-color Doppler sonography and catheter venography of the internal jugular veins (IJVs) to evaluate contrast medium clearance time. In patients with venous outflow anomalies, balloon angioplasty of the IJVs was performed. RESULTS: A contrast medium clearance time cutoff value of 4 seconds or less provided the maximal combination of sensitivity and specificity for the right IJV (sensitivity, 73.4%; specificity, 100%) and left IJV (sensitivity, 91.4%; specificity, 100%). IJVs with a clearance time between 4.1 and 6 seconds had moderate delayed flow (MDF), and IJVs with a clearance time longer than 6 seconds had severe delayed flow (SDF); 89% of patients showed MDF/SDF through at least one IJV, 79% showed MDF/SDF through both IJVs, and only 5% showed normal flow in both IJVs. Balloon angioplasty was immediately able to improve flow in at least one IJV in 69% of patients, but venous flow was normalized in both veins in only 37% of patients; SDF persisted after angioplasty in 32% of patients. CONCLUSIONS: There is a high prevalence of abnormal delayed flow through IJVs in patients with MS. Venous angioplasty was effective in only a minority of patients with SDF.

The aim of the study was to assess adherence to hand washing by healthcare workers (HCWs) and its variations over time in hospital wards. We wanted to check whether the pandemic had changed the behavior of HCWs. The study was conducted between 1 January 2015, and 31 December 2020. The HCWs were observed to assess their compliance with the Five Moments for Hand Hygiene. We described the percentage of adherence to World Health Organization (WHO) guidelines stratified per year, per specialty areas, per different types of HCWs. We also observed the use of gloves. Descriptive data were reported as frequencies and percentages. We observed 13,494 hand hygiene opportunities. The majority of observations concerned nurses who were confirmed as the category most frequently involved with patients. Hospital's global adherence to WHO guidelines did not change in the last six years. During the pandemic, the rate of adherence to the procedure increased significantly only in Intensive Care Unit (ICU). In 2020, the use of gloves increased in pre-patient contact. The hand-washing permanent monitoring confirmed that it is very difficult to obtain the respect of correct hand hygiene in all opportunities, despite the ongoing pandemic and the fear of contagion.
RESUMO
We found significant elevated incidence of hypospadias in two towns in Southeastern Sicily selected on the basis of the presence of intense industrial (Augusta) and agricultural (Vittoria) activities. Cases and controls were chosen in records collected from a surveillance system on abnormal live births in the same area and in a large city (Catania) located in an area at low risk of exposure to environmental pollutants. From 1991 to 1998, 16 cases of isolated hypospadias were recorded among male live births in Augusta (12.1 per 1000 male live births) and 24 cases in Vittoria (7.4 per 1000 male live births) with an incidence significantly higher than that expected (3.2 per 1000 in Southeastern Sicily). Relative risks in Augusta and Vittoria were 3.8 (95% confidence interval: 2.16-6.14) and 2.3 (95% confidence interval: 1.48-3.43; P=0.00003 and 0.04, respectively). In Augusta, the incidence of hypospadias was higher than in Vittoria. Significant log odds ratios were found for occupational exposure in fathers both in Augusta and Vittoria (P=0.0478 and 0.026, respectively). However, daily contact with pollutants in Augusta may not be sufficient by itself to determine hypospadias and other factors might be involved. Similar factors may act also in Vittoria. Thus, contact with large amounts of pesticides is, by itself, a risk factor for hypospadias, though genetic and other environmental factors might be involved.

The aim of this study was to evaluate whether supplementation of acetyl-L-carnitine (ALC) to pegylated-interferon-α 2b (Peg-IFN-α 2b) and ribavirin (RBV) improves the health-related quality of life during the treatment for chronic hepatitis C, thereby decreasing the risk of treatment discontinuation. Sixty patients with chronic hepatitis C underwent treatment with Peg-IFN-α 2b + RBV (group A; n = 29) or Peg-IFN-α 2b + RBV + ALC (group B; n = 31) for 12 months. At the end of the study, the comparison between group A and group B showed significant differences in aspartate aminotransferase (AST) (-80.9 versus -110.3; P < 0.001), alanine aminotransferase (-111.6 versus -134.7; P < 0.001), Viremia (-3.26 versus -3.82; P < 0.05), mental health (0 versus 11; P < 0.001), physical functioning (-1 versus 8; P < 0.001), role-physical (1 versus 13; P < 0.001), bodily pain (1 versus 12; P < 0.001), general health (3 versus 12; P < 0.001), vitality (3 versus 13; P < 0.001), social functioning (3 versus 10; P < 0.001), physical fatigue (2.1 versus -5.4; P < 0.001), mental fatigue (-0.7 versus -2.7; P < 0.001), and fatigue severity scale (-3.4 versus -12; P < 0.001). ALC supplementation reduced both mental and physical fatigue, improved health-related quality of life, and, therefore, has the potential to increase patient adherence to the combination regimen. This, in turn, may increase the percentage of patients achieving a sustained virological response.
