Comparison between use of a pleural drainage system with flutter valve and a conventional water-seal drainage system after lung resection: a randomized prospective study.

Background: There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications.

Objectives: To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber.

Design And Setting: A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil.

Stage II and stage III periodontitis clinical burdens of HIV-1 undergoing antiretroviral therapy.

Objectives: The aim of this retrospective cross-sectional study was to estimate the association of HIV-1 infection under highly active antiretroviral treatment (HAART) on the clinical parameters of periodontitis.

Materials And Methods: A total of 205 patients were divided in two groups: 74 HIV + and 131 HIV - . Periodontal probing depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), and visible supragingival biofilm (VSB) were recorded.

Dental implants in individuals living with HIV-1: Results from a prospective study in patients undergoing highly active antiretroviral therapy.

Objective: To assess survival and success rates of dental implants and the occurrence of peri-implant diseases (mucositis/peri-implantitis) in HIV-1-infected individuals.

Material And Methods: In this prospective study, 13 HIV-1-infected individuals undergoing highly active antiretroviral therapy (with undetectable plasma HIV RNA levels, and CD4+ T cells > 350/mm ) were followed after implant placement, as well as 13 non-HIV-1-infected matched controls. Patients enrolled in this study were followed up to 120 months (mean = 40.

Odontogenic sinusitis: a comprehensive review.

Odontogenic sinusitis (OS) is a highly prevalent, underappreciated and underdiagnosed disease that has been known for over 100 years. Apical periodontitis, periodontal disease and iatrogenic extrusion of foreign bodies into the sinus are the main causes of OS. Although the prevalence of sinus pathosis of dental origin is still controversial, otolaryngologists recognize that in the presence of recalcitrant sinusitis, a dental origin should be considered and properly treated.

Dental implants and bone augmentation in HIV-infected patients under HAART: Case report and review of the literature.

The present study reviewed the literature regarding dental implants in HIV-infected patients and reports the long-term follow-up of three clinical cases of patients under HAART that received bone augmentation and dental implants. The first case presents a young patient with a large defect in the mandible, as a consequence of a longitudinal fracture, that was treated with guided bone regeneration (GBR) previously to implant placement. The second case reported is middle-aged man with a fractured upper lateral incisor treated with immediate placement and simultaneous GBR to repair the dehiscence due to the buccal bone resorption.

Experimental Lachesis muta rhombeata envenomation and effects of soursop (Annona muricata) as natural antivenom.

Background: In the Atlantic forest of the North and Northeast regions of Brazil, local population often uses the fruit juice and the aqueous extract of leaves of soursop (Annona muricata L.) to treat Lachesis muta rhombeata envenomation. Envenomation is a relevant health issue in these areas, especially due to its severity and because the production and distribution of antivenom is limited in these regions.

Spectrum of abdominal imaging findings in histiocytic disorders.

Objectives: The present article provides an overview of the spectrum of abdominal findings of histiocytic disorders that may be observed in multimodality imaging illustrated by clinical cases from our Imaging Center.

Methods: We will review abdominal findings of Langerhans cell histiocytosis, Rosai-Dorfman disease, Erdheim-Chester disease, and hemophagocytic syndrome illustrated by clinical cases from our imaging department with histologic correlation.

Results: Abdominal involvement of histiocytic disorders is rare and may occur in the liver, biliary tract, kidney, retroperitoneum, kidney, gastrointestinal tract, and lymph nodes.

Levels of HIV-1 in subgingival biofilm of HIV-infected patients.

Aim: The aims of the current study were to compare the levels of HIV-1 in the subgingival biofilm (SHVL) between detectable and undetectable plasmatic HIV-1 viral load (PHVL) in HIV-infected patients as well as to determine the association of SHVL with PHVL and clinical periodontal parameters.

Material And Methods: Forty-one HIV-infected individuals were divided into two groups: detectable (21) and undetectable (20) PHVL. Subgingival biofilm samples were obtained for detection and quantification of HIV-1 by real-time RT-PCR.

Morbidity, mortality, and categorization of the risk of perioperative complications in lung cancer patients.

Objective: To determine morbidity and mortality rates by risk category in accordance with the American College of Chest Physicians guidelines, to determine what role pulmonary function tests play in this categorization process, and to identify risk factors for perioperative complications (PCs).

Methods: This was a historical cohort study based on preoperative and postoperative data collected for cases of lung cancer diagnosed or suspected between 2001 and 2010.

Results: Of the 239 patients evaluated, only 13 (5.

The association between detectable plasmatic human immunodeficiency virus (HIV) viral load and different subgingival microorganisms in Brazilian adults with HIV: a multilevel analysis.

Background: This study investigates the association between detectable plasmatic human immunodeficiency virus (HIV) viral load (HVL) and high levels of periodontal- and non-periodontal-related microorganisms in the subgingival microbiota of individuals with HIV.

Methods: Thirty-seven individuals with HIV were divided into two groups: 1) detectable HVL (n = 15); and 2) undetectable HVL (n = 22). Subgingival biofilm samples were obtained, and the levels of 35 microbial species were determined by the checkerboard DNA-DNA hybridization method.

Comparison of the photodynamic fungicidal efficacy of methylene blue, toluidine blue, malachite green and low-power laser irradiation alone against Candida albicans.

This study was to evaluate specific effects of photodynamic therapy (energy density 15.8 J/cm(2), 26.3 J/cm(2) and 39.

Repeat pulmonary thromboendarterectomy after recurrence of chronic thromboembolic pulmonary hypertension.

Pulmonary thromboendarterectomy has been established as the standard method for the treatment of chronic thromboembolic pulmonary hypertension, with excellent results. However, repeat pulmonary thromboendarterectomy due to recurrence of pulmonary embolism has never been reported in the Brazilian literature. Its safety and effectiveness remain obscure.

Distribution of FcγRIIa and FcγRIIIb Genotypes in Patients With Generalized Aggressive Periodontitis.

Background: Polymorphisms in FcγR have been associated with different forms of periodontitis. This study determined the frequency of FcγRIIa and FcγRIIIb alleles/genotypes in patients with generalized aggressive periodontitis (GAgP).

Methods: Thirty-one GAgP and 49 periodontally healthy Brazilian subjects participated in the study.

Distribution of FcgammaRIIa and FcgammaRIIIb genotypes in patients with generalized aggressive periodontitis.
