Comparison of 4% articaine with epinephrine (1:100,000) and without epinephrine in inferior alveolar block for tooth extraction: double-blind randomi…

2011

The purpose of this clinical prospective, randomized, double-blind study was to compare the anesthetic efficacy of 4% articaine with epinephrine (1:100,000) and without epinephrine in inferior alveolar nerve block anesthesia for extractions of mandibular teeth.Eighty-eight patients received intraoral inferior alveolar nerve blocks using 4% articaine with 1:100,000 epinephrine (n = 41; group 1) or without epinephrine (n = 47; group 2) for extractions of mandibular teeth. The primary objectives were differences in onset as well as in length of soft tissue anesthesia. The amount of anesthetic solution, need of a second injection, pain while injecting, pain during treatment, postoperative pain,…

A minor modification of Lichtenstein repair of primary inguinal hernia: postoperative discomfort evaluation.

2010

The aim of this study was to evaluate the usefulness of a modification of the Lichtenstein hernioplasty procedure by evaluating its impact on postoperative discomfort. From December 1999 to May 2006, the Lichtenstein inguinal hernioplasty was performed in 406 patients with noncomplicated unilateral inguinal hernia. During reconstruction, the mesh was fixed to the inguinal canal floor without stitching its upper margin to the internal oblique muscle. Control of postoperative pain proved to be satisfactory; 72 hours after surgery, 26.1 per cent of patients no longer felt any pain, whereas 54.4 per cent had slight pain without the need for painkillers; on Day 7, 92.8 per cent felt no pain at …

Perioperative antibiotic prophylaxis in plastic surgery: A prospective study of 1100 adult patients.

2011

Summary Background Although guidelines for antibiotic prophylaxis to prevent surgical site infections (SSIs) exist, specific guidelines for plastic surgery are missing and there is a tendency towards excessive administration of antibiotics. A total of 1100 patients were prospectively studied according to an evidence-based protocol to investigate if limiting antibiotic prophylaxis to high-risk cases does increase the infection rate. Methods Between April 2009 and April 2010, 1100 consecutive patients undergoing elective reconstructive or cosmetic procedures were enrolled. Procedures were classified into four groups, and prophylactic antibiotics were only administered perioperatively in 23.4%…

Left ventricular mass in hypertensive patients with mild-to-moderate reduction of renal function

2010

Aim: Left ventricular hypertrophy (LVH) is an independent predictor of cardiovascular (CV) morbidity and mortality. The aim of the present study was to evaluate the relationship between LV mass and mild-to-moderate renal dysfunction in a group of non-diabetic hypertensives, free of CV diseases, participating in the Renal Dysfunction in Hypertension (REDHY) study. Methods: Patients with diabetes, a body mass index (BMI) of more than 35 kg/m 2 , secondary hypertension, CV diseases and a glomerular filtration rate (GFR) of less than 30 mL/min per 1.73 m 2 were excluded. The final sample included 455 patients, who underwent echocardiographic examination and ambulatory blood pressure monitoring.…

Comparative study of neurocognitive function in euthymic bipolar patients and stabilized schizophrenic patients.

2009

Few studies have compared neurocognitive performance in euthymic patients with bipolar disorder (BD), stabilized patients with schizophrenia (SC) and normal controls (NC) using a comprehensive neuropsychological battery, and those that have been conducted have yielded discrepant results. We evaluated the neurocognitive profile shown by 73 euthymic patients with BD, 89 stabilized patients with SC and 67 NC. All participants completed a cognitive battery in which the domains evaluated were executive functioning, sustained attention, and verbal and visual memory. Individuals with BD were administered the Quality of Life Scale (QLS). Patients with BD manifested dysfunction in executive function…

Do patients with bipolar disorder and subsyndromal symptoms benefit from functional remediation? A 12-month follow-up study

2016

We analyzed the efficacy of functional remediation, in a sample of patients with bipolar disorder who presented with subsyndromal symptoms. From a total sample of 239 patients with bipolar I and II disorder, according to DSM-IV-TR diagnostic criteria, entering a randomized clinical trial, those patients who presented with subsyndromal symptoms were selected based on a method already described by Berk and colleagues was applied. It consists of using the Clinical Global Impression-Bipolar version (CGI-BP) to establish the scores of the Hamilton Depression Rating Scale (HAM-D) and of the Young Mania Rating Scale (YMRS) that correspond with 1 in the CGI-BP. Functional outcome and mood symptoms …

Erectile dysfunction is associated with low total serum testosterone levels and impaired flow-mediated vasodilation in intermediate risk men accordin…

2015

Background: The role erectile dysfunction (ED) coupled with low testosterone levels as early markers of atherosclerosis is not well understood. Objectives: To analyze the relationship between serum testosterone levels with both ED and brachial artery flow-mediated vasodilation (FMD), in a primary prevention sample of men. Methods: We enrolled 802 asymptomatic, intermediate CV risk patients, according to the Framingham Risk Score, aged 40e80 years, who underwent the ultrasound examination of FMD, the evaluation of ED and the assessment of total serum testosterone levels. Results: Testosterone levels correlated both with FMD (r ¼ 0.85; p < 0.0001) and IIEF-5 score (rs ¼ 0.65; p < 0.0001…

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…
