Trans-cultural aspects of social anxiety disorder and related conditions: a Brazilian case series and a review of international clinical studies

Cross-cultural studies have much to teach clinicians and researchers alike about psychopathology in general and about social anxiety disorder (SAD) in particular. Unfortunately, little is known about the degree and the mechanisms through which cultural environment may influence clinical manifestations of SAD. OBJECTIVE: Our objective was to identify culture-related clinical patterns in SAD and related disorders. METHODS: We described socio-demographic and clinical characteristics of a sample of 62 adult outpatients with SAD seen at a university clinic for anxiety and depressive disorders in Rio de Janeiro, Brazil, and compared them with those reported in clinical samples from North America, Europe, Asia and Oceania identified through a systematic review in Medline, PsychINFO, and LILACS. RESULTS: Our comparison of trans-cultural features of SAD lends partial support to Heimberg's (1997) contention that the majority of socio-demographic features and symptoms of this disorder are relatively independent of geographic and cultural differences. CONCLUSION: Patients with SAD were almost universally characterized by: 1) a predominance of males in clinical samples; 2) early onset of the disorder; 3) high educational attainment; and 4) great frequency of comorbidities.

Ultrasound enhances lipase-catalyzed synthesis of poly (ethylene glutarate)

The present work explores the best conditions for the enzymatic synthesis of poly (ethylene glutarate) for the first time. The start-up materials are the liquids; diethyl glutarate and ethylene glycol diacetate, without the need of addition of extra solvent. The reactions are catalyzed by lipase B from Candida antarctica immobilized on glycidyl methacrylate-ter-divinylbenzene-ter-ethylene glycol dimethacrylate at 40 °C during 18 h in water bath with mechanical stirring or 1 h in ultrasonic bath followed by 6 h in vacuum in both the cases for evaporation of ethyl acetate. The application of ultrasound significantly intensified the polyesterification reaction with reduction of the processing time from 24 to 7 h. The same degree of polymerization was obtained for the same enzyme loading in less time of reaction when using the ultrasound treatment. The degree of polymerization for long-term polyesterification was improved approximately 8-fold due to the presence of sonication during the reaction. The highest degree of polymerization achieved was 31, with a monomer conversion of 96.77%. The ultrasound treatment demonstrated to be an effective green approach to intensify the polyesterification reaction with enhanced initial kinetics and high degree of polymerization.

Preoperative staging of rectal cancer with MRI: correlation with pathologic staging

[INTRODUCTION] An accurate preoperative rectal cancer staging is crucial to the correct management of the disease. Despite great controversy around this issue, pelvic magnetic resonance (RM) is said to be the imagiologic standard modality. This work aimed to evaluate magnetic resonance accuracy in preoperative rectal cancer staging comparing with the anatomopathological results. METHODS We calculated sensibility, specificity, positive (VP positive) and negative (VP negative) predictive values for each T and N. We evaluated the concordance between both methods of staging using the Cohen weighted K (Kw), and through ROC curves, we evaluated magnetic resonance accuracy in rectal cancer staging. RESULTS 41 patients met the inclusion criteria. We achieved an efficacy of 43.9% for T and 61% for N staging. The respective sensibility, specificity, positive and negative predictive values are 33.3%, 94.7%, 33.3% and 94.7% for T1; 62.5%, 32%, 37.0% and 57.1% for T2; 31.8%, 79%, 63.6% and 50% for T3 and 27.8%, 87%, 62.5% and 60.6% for N. We obtained a poor concordance for T and N staging and the anatomopathological results. The ROC curves indicated that magnetic resonance is ineffective in rectal cancer staging. CONCLUSION Magnetic resonance has a moderate efficacy in rectal cancer staging and the major difficulty is in differentiating T2 and T3.

Fechamento percutâneo de comunicação interatrial por punção trans-hepática

O fechamento percutâneo da comunicação interatrial (CIA) ostium secundum (OS) é procedimento bem estabelecido, sendo atualmente considerado o tratamento de escolha por seus bons resultados e sua baixa morbidade e mortalidade. O procedimento é realizado rotineiramente pela veia cava inferior (VCI). Ocasionalmente, entretanto, essa via de acesso não é possível por causa da obstrução ou da ausência congênita da VCI. Apresentaremos um caso de fechamento de CIA por punção trans-hepática decorrente de impossibilidade de uso da VCI.

Prácticas alimentarias y su relación con cáncer colo-rectal: un estudio de casos y controles en Córdoba

En los países desarrollados el cáncer colo-rectal es el responsable del 6% del total de la mortalidad por cáncer. En Córdoba representa la 3ra. causa de muerte en las mujeres y la 5ta. en los varones. (...) Varios estudios epidemiológicos y experimentales han identificado ciertos componentes de la dieta como factores que modifican el riesgo de padecer esta enfermedad, ya sea aumentándolo (promotores) como disminuyéndolo (antipromotores). Analizar las prácticas alimentarias de nuestra población en relación a la determinación de los mencionados factores constituye uno de los pilares fundamentales para la formulación de planes y programas de educación alimentaria y nutricional. Objetivos: 1. Determinar, mediante el enfoque de riesgo, la relación entre las prácticas alimentarias y cáncer colo-rectal, en pacientes que presentan esta patología y sus controles, provenientes de instituciones públicas y privadas de la ciudad de Córdoba. 2. Establecer la asociación entre cáncer colo-rectal y consumo de lípidos (en especial referencia a las variedades de familias de ácidos grasos que los componen), colesterol, glúcidos, proteínas, fibra total, soluble e insoluble, alcohol y algunas vitaminas y minerales. 3. Determinar la relación entre cáncer colo-rectal, consumo de alimentos y técnicas y procedimientos de cocción.

Ultrasound Blocks for the Anterior Abdominal Wall - Adult and Pediatric Surgery

Somatic post-surgical pain is invalidating and distressing to patients and carries the risk of important complications. The anterior abdominal wall is involved in most surgical procedures in general, gynecologic, obstetric, urological, vascular and pediatric surgery. Combined multimodal strategies involving nerve blocks, opiates, and non-steroidal anti-inflammatory drugs for systemic analgesia are necessary for optimal pain modulation. Anterior abdominal wall blocks, transverse abdominal plexus block, iliohypogastric and ilioinguinal nerveblock, genitofemoral nerve block and rectus sheath block have an important role as components of multimodal analgesia for somatic intraoperative and postoperative pain control. Ultrasound visualization has improved the efficacy and safety of abdominal blocks and implemented the application in the clinical setting. For this reason, they are a very important tool for all anesthesiologists who aim to treat effectively patients’ pain. This guide provides an evidence based comprehensive and necessary overview of anatomical, anesthesiological and technical information needed to safely perform these blocks.

Focused Cardiac Ultrasound Using a Pocket-Size Device in the Emergency Room

Background:Cardiovascular urgencies are frequent reasons for seeking medical care. Prompt and accurate medical diagnosis is critical to reduce the morbidity and mortality of these conditions.Objective:To evaluate the use of a pocket-size echocardiography in addition to clinical history and physical exam in a tertiary medical emergency care.Methods:One hundred adult patients without known cardiac or lung diseases who sought emergency care with cardiac complaints were included. Patients with ischemic changes in the electrocardiography or fever were excluded. A focused echocardiography with GE Vscan equipment was performed after the initial evaluation in the emergency room. Cardiac chambers dimensions, left and right ventricular systolic function, intracardiac flows with color, pericardium, and aorta were evaluated.Results:The mean age was 61 ± 17 years old. The patient complaint was chest pain in 51 patients, dyspnea in 32 patients, arrhythmia to evaluate the left ventricular function in ten patients, hypotension/dizziness in five patients and edema in one patient. In 28 patients, the focused echocardiography allowed to confirm the initial diagnosis: 19 patients with heart failure, five with acute coronary syndrome, two with pulmonary embolism and two patients with cardiac tamponade. In 17 patients, the echocardiography changed the diagnosis: ten with suspicious of heart failure, two with pulmonary embolism suspicious, two with hypotension without cause, one suspicious of acute coronary syndrome, one of cardiac tamponade and one of aortic dissection.Conclusion:The focused echocardiography with pocket-size equipment in the emergency care may allow a prompt diagnosis and, consequently, an earlier initiation of the therapy.

Diagnosing pulmonary embolism in outpatients with clinical assessment, D-dimer measurement, venous ultrasound, and helical computed tomography: a multicenter management study.

PURPOSE: To evaluate a diagnostic strategy for pulmonary embolism that combined clinical assessment, plasma D-dimer measurement, lower limb venous ultrasonography, and helical computed tomography (CT). METHODS: A cohort of 965 consecutive patients presenting to the emergency departments of three general and teaching hospitals with clinically suspected pulmonary embolism underwent sequential noninvasive testing. Clinical probability was assessed by a prediction rule combined with implicit judgment. All patients were followed for 3 months. RESULTS: A normal D-dimer level (<500 microg/L by a rapid enzyme-linked immunosorbent assay) ruled out venous thromboembolism in 280 patients (29%), and finding a deep vein thrombosis by ultrasonography established the diagnosis in 92 patients (9.5%). Helical CT was required in only 593 patients (61%) and showed pulmonary embolism in 124 patients (12.8%). Pulmonary embolism was considered ruled out in the 450 patients (46.6%) with a negative ultrasound and CT scan and a low-to-intermediate clinical probability. The 8 patients with a negative ultrasound and CT scan despite a high clinical probability proceeded to pulmonary angiography (positive: 2; negative: 6). Helical CT was inconclusive in 11 patients (pulmonary embolism: 4; no pulmonary embolism: 7). The overall prevalence of pulmonary embolism was 23%. Patients classified as not having pulmonary embolism were not anticoagulated during follow-up and had a 3-month thromboembolic risk of 1.0% (95% confidence interval: 0.5% to 2.1%). CONCLUSION: A noninvasive diagnostic strategy combining clinical assessment, D-dimer measurement, ultrasonography, and helical CT yielded a diagnosis in 99% of outpatients suspected of pulmonary embolism, and appeared to be safe, provided that CT was combined with ultrasonography to rule out the disease.
