Comparação entre o sistema Autoścan-4 e métodos convencionais na identificação de bacilos Gram-negativos não fermentadores, isolados de materiais clínicos de pacientes em Presidente Prudente - SP

Ninety eight strains of glucose-nonfermenting Gram-negative bacilli were analyzed and isolated from several clinical materials of 95 patients admitted at the Dr. Domingos Leonardo Cerávolo University Hospital and three from outpatients. All of them were assisted in the Laboratory of Clinical Analysis of Unoeste University, Presidente Prudente, SP, from the period of October of 1999 to April of 2001. In this work, the level of agreement between the semi-automated commercial system AutoScan-4 and the conventional system for the identification of those bacteria were studied comparatively. There was agreement in 81 (82.7%), showing that both methodologies are useful for identification; partial agreement in six strains (6.1%) and disagreement in 11 (11.2%). The comercial system did not identify nine (9.2%) of the strains and reported them as very rare biotypes.

Padrão de sensibilidade aos antimicrobianos de bacilos gram-negativos não fermentadores isolados de materiais clínicos de pacientes em Presidente Prudente - SP

The aim of this study was the assessment of isolation frequency and antimicrobial susceptibility pattern of nonfermenting Gram-negative bacilli. Ninety eight strains of nonfermenting Gram-negative bacilli, isolated from several clinical materials of patients admited at the Dr. Domingos Leonardo Cerávolo University Hospital and at Dr. Odilo Antunes Siqueira State Hospital, as well as from every outpatient; assisted at Laboratory of Clinical Analysis of Unoeste University, Presidente Prudente, São Paulo, in the period of October 1999 to April 2001 were analyzed. The most frequent species were Pseudomonas aeruginosa (65.3%) and Acinetobacter baumannii (23.5%). The frequency of the other isolated species was smaller than 2.5%. In the antimicrobial susceptibility tests, the two species more prevalent showed high resistance. The antibiotic most active in vitro was the imipenem, with 79.6% in microdiluition method, and 76.6% in diffusion method, for Pseudomonas aeruginosa strains and 100.0% in both microdiluition and diffusion methods, for Acinetobacter baumannii. The cephalosporins of third generation, the ciprofloxacin and the aminoglycosides, presented percentage of susceptibility varying from 22.4 to 69.7%. These results bring implications to the emergency use of the antimicrobial agents in the treatment of patients with severe infection.

Juvenile localized scleroderma: Clinical and epidemiological features in 750 children. An international study

Objective. Juvenile localized scleroderma (JLS) includes a number of conditions often grouped together. With the long-term goal of developing uniform classification criteria, we studied the epidemiological, clinical and immunological features of children with JLS followed by paediatric rheumatology and dermatology centres. Methods. A large, multicentre, multinational study was conducted by collecting information on the demographics, family history, triggering environmental factors, clinical and laboratory features, and treatment of patients with JLS. Results. Seven hundred and fifty patients with JLS from 70 centres were enrolled into the study. The disease duration at diagnosis was 18 months. Linear scleroderma (LS) was the most frequent subtype (65%), followed by plaque morphea (PM) (26%), generalized morphea (GM) (7%) and deep morphea (DM) (2%). As many as 15% of patients had a mixed subtype. Ninety-one patients (12%) had a positive family history for rheumatic or autoimmune diseases; 100 (13.3%) reported environmental events as possible trigger. ANA was positive in 42.3% of the patients, with a higher prevalence in the LS-DM subtype than in the PM-GM subtype. Scl70 was detected in the sera of 3% of the patients, anticentromere antibody in 2%, anti-double-stranded DNA in 4%, anti-cardiolipin antibody in 13% and rheumatoid factor in 16%. Methotrexate was the drug most frequently used, especially during the last 5 yr. Conclusion. This study represents the largest collection of patients with JLS ever reported. The insidious onset of the disease, the delay in diagnosis, the recognition of mixed subtype and the better definition of the other subtypes should influence our efforts in educating trainees and practitioners and help in developing a comprehensive classification system for this syndrome. © 2006 Oxford University Press.

Experimental envenomation with Crotalus durissus terrificus venom in dogs treated with antiophidic serum - Part I: Clinical evaluation, hematology and myelogram

The present study aimed at evaluating clinical and laboratory aspects during experimental envenomation by Crotalus durissus terrificus in dogs treated with antiophidic serum. Twenty-one dogs were divided into three groups of seven animals each. Group I received 1mg/kg venom (sc); Group II received 1mg/kg venom (sc), 50mg antiophidic serum (iv), and fluid therapy including 0.9% NaCl solution (iv); and Group III received 1mg/kg venom (sc), 50mg antiophidic serum (iv), and fluid therapy including 0.9% NaCl solution containing sodium bicarbonate diluted to the dose of 4mEq/kg. The clinical signs of ataxia, sedation, flaccid paralysis, mydriasis, eyeball paralysis, mandible ptosis, sialorrhea, vomiting and diarrhea observed in the dogs were very similar to those observed in humans. The decrease in hemoglobin, hematocrit, erythrocyte, platelet and fibrinogen levels, prolongation of clotting time, prothrombin time (PT) and activated partial thromboplastin time (APTT), as well as hypocellularity in the bone marrow characterized anemia, thrombocytopenia and blood incoagulability, as well as hypofibrinogenemia and decreased bone-marrow activity. Important bleeding was not observed. Increased numbers of leukocytes and neutrophils and decreased numbers of lymphocytes and eosinophils characterized an acute inflammatory response and stress caused by generalized pain. The employed antiophidic serum was effective and all animals survived.

Razão triglicérides/HDL-C e proteína C reativa de alta sensibilidade na avaliação do risco cardiovascular

Introduction: Calculated indexes from laboratory measurements and the determination of plasma markers are commonly used in cardiovascular risk assessment. Objective: To use triglycerides/high-density lipoprotein cholesterol (HDL-C) ratio, estimate of low-density lipoprotein (LDL) particle size and high sensitive C-reactive protein (hs-CRP) levels to the clinical and laboratorial assessment of coronary risk among patients with coronary disease. Material and methods: Sixty patients were chosen accordingly, 36 female (F) (65 ± 9 years of age) and 24 male (M) (55 ± 10 years of age) diagnosed with stable ischemic cardiopathy at Ana Neri Hospital, Salvador, Bahia, Brazil. The investigation was carried out at the Clinical Biochemistry Laboratory of the College of Pharmacy at Federal University of Bahia (UFBA). Blood samples were collected after a 12-hour fast to determine hs-CRP, lipid profile and risk indicators. All data were assessed through Syncron LX®20 Beckman Coulter. The inferential analysis results were considered significant when p ≤ 5%. Data analysis was carried out with GraphPad Prism® (4.03 version) software. Results: Data analysis showed a positive correlation between hs-CRP and triglycerides/HDL-C ratio only among women (r = 0.4; p = 0.0442), n = 36. The analysis of other parameters did not show any significance. Conclusion: The triglycerides/HDL-C ratio and hs-CRP may be used as indicators of increase in cardiovascular risk among women with coronary artery disease (CAD).

Clinical and molecular study of a new form of hereditary myotonia in Murrah water buffalo

Hereditary myotonia caused by mutations in CLCN1 has been previously described in humans, goats, dogs, mice and horses. The goal of this study was to characterize the clinical, morphological and genetic features of hereditary myotonia in Murrah buffalo. Clinical and laboratory evaluations were performed on affected and normal animals. CLCN1 cDNA and the relevant genomic region from normal and affected animals were sequenced. The affected animals exhibited muscle hypertrophy and stiffness. Myotonic discharges were observed during EMG, and dystrophic changes were not present in skeletal muscle biopsies; the last 43 nucleotides of exon-3 of the CLCN1 mRNA were deleted. Cloning of the genomic fragment revealed that the exclusion of this exonic sequence was caused by aberrant splicing, which was associated with the presence of a synonymous SNP in exon-3 (c.396C>T). The mutant allele triggered the efficient use of an ectopic 5' splice donor site located at nucleotides 90-91 of exon-3. The predicted impact of this aberrant splicing event is the alteration of the CLCN1 translational reading frame, which results in the incorporation of 24 unrelated amino acids followed by a premature stop codon.

Maxillary Rehabilitation Using Fixed and Removable Partial Dentures with Attachments: A Clinical Report

Despite requiring dental crown preparation and possible root canal treatment, besides the difficulty of clinical and laboratory repairs, and financial burden, the association between fixed (FPD) and removable partial dentures (RPD) by means of attachments is an important alternative for oral rehabilitation, particularly when the use of dental implants and FPDs is limited or not indicated. Among the advantages of attachment-retained RPDs are the improvements in esthetics and biomechanics, as well as correction of the buccal arrangement of anterior teeth in Kennedy Class III partially edentulous arches. This article describes the treatment sequence and technique for the use of attachments in therapy combining FPD/RPD. © 2013 by the American College of Prosthodontists.
