An emergent infectious disease: Clostridioides difficile infection hospitalizations, 10-year trend in Sicily
2021
Abstract Background Clostridioides difficile is the most common cause of healthcare-associated diarrhoea worldwide and C. difficile infection is an emerging infectious disease. In the US, its rates are monitored trough an active surveillance system, but many European Union member states still lack this, and in Italy no epidemiological data on C. difficile infection are available except for a few single-centre data. Aim To provide data on the C. difficile infection incidence in Sicily (the biggest and 5th most populous region of Italy) during a 10-year period. Methods We revised all the regional standardized discharge forms between 2009 and June 2019 using the code ICD-9 00845 of the Interna…
Mycobacterial Infection: A Difficult and Late Diagnosis in Stem Cell Transplant Recipients
2004
The Infectious Diseases Working Party of the European Blood and Marrow Transplant Group conducted a survey to obtain information about the frequency, presentation, and treatment of mycobacterial infection (MBI) in stem cell transplant (SCT) recipients. Among 29 centers, MBI was diagnosed in 0.79% of 1513 allogeneic and 0.23% of 3012 autologous SCT recipients during 1994-1998 a median of 160 days after transplantation. The mean interval between first symptoms and diagnosis was 29 days and was still longer for patients with atypical MBI or recipients of corticosteroid therapy. The prevalence of MBI was highest among those who received matched unrelated or mismatched STCs from related donors. …
Incidence of posterior vitreous detachment after cataract surgery
2009
Purpose To report the incidence of posterior vitreous detachment (PVD) after uneventful state-of-the-art small-incision phacoemulsification with implantation of a posterior chamber intraocular lens (PC IOL). Setting Department of Ophthalmology, Ludwigshafen Hospital, Ludwigshafen, Germany. Methods This prospective study evaluated the vitreous status of eyes by biomicroscopic examination, indirect binocular ophthalmoscopy, and B-scan ultrasonography before planned cataract surgery. Patients with the posterior vitreous attached were included for follow-up and examined 1 week, 1 month, and 1 year after uneventful phacoemulsification with PC IOL implantation. The preoperative prevalence and pos…
Follow-up after transanal endoscopic microsurgery or transanal excision of large benign rectal polyps
1998
Methods: Between January 1986 and December 1995, 238 patients with benign rectal polyps under-went either transanal endoscopic microsurgery (n = 226) or transanal excision (n = 12) at the Clinic of General and Abdominal Surgery, Johannes Gutenberg-University, Mainz. Results: Mean polyp size was 4.2 cm; 89.1% of polyps measured more than 2 cm in diameter. In 89.1% of cases, histological analysis revealed polyps containing tubulovillous or villous adenomas. Synchronous colonic polyps were detected in 12.5% of patients. Follow-up data are available on 222 patients (94%). At follow-up examination, 169 of the 193 surviving patients (87.6%) were recurrence free. Seven of 193 patients (3.6%) had d…
Soft tissue pathosis associated with asymptomatic impacted lower third molars
2010
Objective: The aim of this study was to identify the prevalence of pathological changes in the pericoronal tissue of asymptomatic impacted lower third molars and to assess the correlation between pathological changes and patient demographic, radiographic and morphological characteristics. Study Design: Follicles associated with fully impacted lower third molars were submitted for histological examiDesign: Follicles associated with fully impacted lower third molars were submitted for histological examiesign: Follicles associated with fully impacted lower third molars were submitted for histological examination after surgical extraction from 50 patients.

Sensibility and taste alterations after impacted lower third molar extractions. A prospective cohort study
2012
Objectives: To determine the incidence, severity and duration of lingual tactile and gustatory function impairments after lower third molar removal. Study Design: Prospective cohort study with intra-subject measures of 16 patients undergoing lower third molar extractions. Sensibility and gustatory functions were evaluated in each subject preoperatively, one week and one month after the extraction, using Semmes-Weinstein monofilaments and 5 different concentrations of NaCl, respectively. Additionally, all patients filled a questionnaire to assess subjective perceptions. Results: Although patients did not perceive any sensibility impairments, a statistically significant decrease was detected …
Complications in third molar removal: A retrospective study of 588 patients
2010
Objectives: Surgical removal of third molars is a regular surgical procedure, which like all operations, may have complications. The purpose of the study was to analyze the incidence of complications and their relationship with the surgical difficulty in a group of 588 patients treated by the same oral and maxillofacial surgeon. Study design: This retrospective cohort study consisted of 1699 third molars (M3) removed between 2005 and 2008. The teeth were grouped into a 6-class scale of surgical difficulty rated according to the surgical procedure description in the patient?s file: I: upper M3 requiring forceps only; II: upper M3 requiring osteotomy; III: upper M3 requiring osteotomy and too…
High incidence and increasing prevalence of MS in Enna (Sicily), southern Italy
2001
Twenty years after a first survey, a follow-up study was performed on the prevalence of MS in Enna (Sicily), southern Italy. The prevalence of definite MS rose from 53 to 120.2 per 100,000 population. The incidence of definite MS for the period 1986 to 1995 was 5.7 per 100,000 per year. The innermost part of Sicily shows an elevated prevalence of MS, second only to Sardinia in the Mediterranean area.
Multiple sclerosis in southern Europe: Monreale City, Italy. A twenty-year follow-up incidence and prevalence study.
2004
BACKGROUND: Several follow-up studies showed increasing prevalence and incidence rates for multiple sclerosis (MS). OBJECTIVE:To ascertain, throughout a follow-up study, the incidence and prevalence of MS in the city of Monreale, Sicily, southern Italy. METHODS:We calculated crude and age- and sex-specific prevalence rates on December 31, 2000, and determined incidence rates for the period January 1, 1992 to December 31, 2000. RESULTS:The prevalence of MS was 71.2 per 100,000 population (48,5/100,000 in men; 93,0/100,000 in women). The incidence rate of MS for the period 1992-2000 was 4.0/100,000 per year. CONCLUSION:This study showed a nonsignificant increase in MS incidence rates in Monre…
Radiofrequency electromagnetic fields emitted from base stations of DECT cordless phones and the risk of glioma and meningioma (Interphone Study Grou…
2006
The objective of this study was to test the hypothesis that exposure to continuous low-level radiofrequency electromagnetic fields (RF EMFs) increases the risk of glioma and meningioma. Participants in a population-based case-control study in Germany on the risk of brain tumors in relation to cellular phone use were 747 incident brain tumor cases between the ages of 30 and 69 years and 1494 matched controls. The exposure measure of this analysis was the location of a base station of a DECT (Digital Enhanced Cordless Telecommunications) cordless phone close to the bed, which was used as a proxy for continuous low-level exposure to RF EMFs during the night. Estimated odds ratios were 0.82 (95…
