BYOTYPES AND RANDOMLY AMPLIFIED POLYMORPHIC DNA (RAPD) PROFILES OF SUBGINGIVAL CANDIDA ALBICANS ISOLATES IN HIV INFECTION
2005
ABSTRACT: A group of subgingival isolates of C. albicans recovered from Italian HIV-positive (HIV+) subjects were characterized both phenotypically and genotypically. Phenotyping of the isolates was carried out by a biotyping method based on the enzyme profiles, carbohydrate assimilation patterns and boric acid resistance of the yeasts. Genotyping was performed through randomly amplified polymorphic DNA (RAPD) analysis. Five biotypes were found among the 29 subgingival C. albicans strains examined. The predominant biotypes were A1R (55.17%), A1S (24.14%), and A2R (13.79%), while the biotypes A11R and A13R were represented by a single isolate each. RAPD profiles identified 15 genotypes among…
Ten novel mutations found in Aniridia.
1998
Aniridia (AN) is a sight-threatening congenital ocular disorder characterized by iris hypoplasia, corneal pannus, foveal and optic nerve hypoplasia, cataract formation, and glaucoma. In two-thirds of the patients, AN is inherited in an autosomal dominant fashion with almost complete penetrance but variable expression. The remaining cases are sporadic. Aniridia has been shown to be associated with mutations in the PAX6 gene, located on chromosome 11p13, telomeric to the Wilms' tumor predisposition gene (WT1). This paper describes 14 mutations in the PAX6 gene in patients with AN. Among these 14 mutations, 10 have been unpublished until now. They result most probably in haploinsufficiency and…
Micafungin versus liposomal amphotericin B for candidaemia and invasive candidosis: a phase III randomised double-blind trial
2007
Summary Background Invasive candidosis is increasingly prevalent in seriously ill patients. Our aim was to compare micafungin with liposomal amphotericin B for the treatment of adult patients with candidaemia or invasive candidosis. Methods We did a double-blind, randomised, multinational non-inferiority study to compare micafungin (100 mg/day) with liposomal amphotericin B (3 mg/kg per day) as first-line treatment of candidaemia and invasive candidosis. The primary endpoint was treatment success, defined as both a clinical and a mycological response at the end of treatment. Primary analyses were done on a per-protocol basis. This trial is registered with ClinicalTrials.gov, number NCT00106…
Candidal carriage in the oral cavity of human immunodeficiency virus–infected subjects
2002
Abstract Objectives. We sought to assess asymptomatic oral carriage of Candida species and relative density in human immunodeficiency virus-infected (HIV+) subjects, as well as to determine whether yeast carriage is associated with CD4+cell count, HIV-1 RNA quantity, gender, route of HIV transmission, antiretroviral therapy, or smoking. Study Design. A cross-sectional analysis of oral rinses from HIV+ and healthy subjects was undertaken. Oral candidal carriage and relative species were investigated in 42 HIV+ and 41 healthy individuals, all of whom were seen at the Palermo University Department of Oral Sciences, Italy. Data were managed and analyzed by means of the computer software package…
High volume and low concentration of anaesthetic solution in the perivascular interscalene sheath determines quality of block and incidence of compli…
2006
Background and objective: In the perivascular sheath of the brachial plexus, the volume of anaesthetic solution determines the quality of anaesthetic cover. Fibrous septa may divide the perivascular space into compartments, leading to inadequate diffusion of the anaesthetic solution. The aim of our study was to obtain good anaesthesia and less complications using high volume of low concentration anaesthetic solution, overcoming the obstacle of the septa with a double approach to the scalene sheath. Methods: Sixty patients scheduled for shoulder capsuloplasty received both Winnie interscalene brachial plexus block and Pippa proximal cranial needle approach. The patients were randomly assigne…
Technical note: a comparison of central and peripheral intraocular pressure using rebound tonometry
2007
Purpose: To compare central and peripheral intraocular pressure (IOP) readings obtained with rebound tonometry.Methods: Intraocular pressure was measured on the right eye of 153 patients (65 males, 88 females), aged from 21 to 85 years (mean +/- S.D., 55.5 +/- 15.2 years) with the ICare rebound tonometer at centre, and 2 mm from the limbus (in the nasal and temporal regions along the 0-180O corneal meridian).Results: Intraocular pressure values obtained with the ICare were 14.9 +/- 2.8; 14.1 +/- 2.5 and 14.5 +/- 2.7 mmHg at centre, nasal and temporal corneal locations, respectively. On average, nasal and temporal IOP readings were 0.75 and 0.37 mmHg lower than the central reading (p 0.05, r…
Risk factors of oral candidosis: a twofold approach of study by fuzzy logic and traditional statistic.
2007
Abstract Objective To assess a panel of risk factors associated to oral candidosis (OC) onset and its chronic maintenance by means of fuzzy logic (FL) approach and statistical traditional methodology (STM); to investigate their casual relationship within a multifactorial framework. Design Case–control study. Setting One hospital-based clinic. Patients Eighty-nine patients with OC infection microbiologically diagnosed and 98 healthy subjects were consecutively recruited. Outcome measurements Anamnestic and clinical evaluations for OC, microbiological assessment (i.e. culture, CFU/mL counting and identification) were performed. The commonest predisposing factors for OC onset and its chronic s…
Prevalence and risk factors of diabetic retinopathy in adult and elderly subjects. The Casteldaccia Eye Study
2003
PURPOSE: To investigate the prevalence and risk factors of diabetic retinopathy in subjects aged 40 years or older living in Casteldaccia, Sicily. METHODS: A population-based survey was performed on 1,588 subjects randomly enrolled among people aged 40 years or older. A total of 1,068 persons could be examined and in 1,019 the fundus of the eye was adequately observed (64.2% of the enrolled population). Diabetic retinopathy was diagnosed by ophthalmoscopy and fundus photographs; fluorescein angiography was performed in 91% of retinopathic subjects. In addition, a case-control study was carried out in order to demonstrate the association of diabetic retinopathy with a number of variables. RE…
Risk factors related to oral candidiasis in patients with primary Sjögren’s syndrome
2020
Background Candidiasis is the most frequent mycotic infection of the oral cavity. The aim of this study was to investigate the presence of clinical oral candidiasis and Candida albicans yeast in a population diagnosed of primary Sjögren’s syndrome (pSS) and to study the possible factors associated with this infection. Material and Methods An observational cross-sectional study was conducted in 61 pSS patients (60 women, 1 man, mean age 57.64±13.52) where patient based information (demographic and medical, tobacco and alcohol consumption history), intraoral parameters (presence of dentures, clinical signs of candidiasis), salivary analytical information (number of Candida albicans as colony-…
Gender differences in human immunodeficiency virus–related oral lesions: An Italian study
2001
Abstract Objective: The purpose of this study was to investigate the relationship between oral lesions and gender, age, CD4+ cell count, human immunodeficiency virus-1 (HIV-1) viral load, antiretroviral therapy, and route of transmission in a group of HIV-infected (HIV+) persons from the Mediterranean region. Study Design: The participants in this study were HIV+ adults who sought dental care between January 1999 and June 1999 in the Department of Oral Medicine (University of Palermo, Italy). Results: One hundred thirty-six HIV+ adults came in for an initial oral examination. Their mean age was 35.2 years (SD ± 7.97), and 33% were women. Their mean CD4+ cell count was 325.3 × 106 /L (SD ± 2…
