A WELFARE ANALYSIS OF ECONOMIC FLUCTUATIONS IN SOUTH AMERICA

How large are welfare costs associated with economic aggregate fluctuations is a topic of great concern among economists at least since Robert Lucas' well-known and thought-provoking exercise in the late 1980s. Our analysis assesses the magnitude of such costs for nine countries in South America by means of three alternative trend-cycle decomposition methods. The results suggest South American countries have welfare costs of economic fluctuations notably higher than the U. S. economy.

IMPACTO DA CIRURGIA ORTOGNÁTICA SOBRE A QUALIDADE DE VIDA DE PACIENTES ATENDIDOS NO SERVIÇO DA UNIVERSIDADE FEDERAL DO PARANÁ

A qualidade de vida vem sendo discutida e estudada cada vez mais nos últimos anos quando falamos em saúde, abrindo um leque para o estudo dos impactos que ela pode vir a trazer. A preocupação com a técnica nos procedimentos odontológicos começa a ser percebida de um novo ponto de vista, com maior enfoque no ser humano como um todo. Tendo em mente uma nova concepção de saúde,  o “The Oral Health Impact Profile”  (OHIP) é usado como intrumento para avaliar o impacto de problemas bucais no indivíduo, abrangendo as dimensões física, psicológica e social da vida diária. O OHIP14, versão resumida do OHIP, foi publicado por Slade em 1997. Este estudo, realizado na Universidade Federal do Paraná, avaliou o impacto na qualidade de vida dos pacientes submetidos a cirurgia ortognática a partir do uso desse questionário. O estudo mostrou um impacto negativo na qualidade de vida maior nos indivíduos que apresentam deformidades dentofaciais do que naqueles que não apresentam

Glomus Tumor of the Stomach: A Rare Cause of Upper Gastrointestinal Bleeding

Introduction. Glomus tumors (GTs) are benign neoplasm originating from the glomus body, commonly described in subungual region. The involvement abdominal is rare. Our aim is to describe a case of glomus tumor of the stomach that presented upper gastrointestinal bleeding. A 34-year-old woman was admitted with upper gastrointestinal bleeding and underwent an upper endoscopy that showed bleeding arising from an ulcerated lesion, treated by sclerosis therapy. A new endoscopy confirmed a submucosal lesion in upper portion of the stomach. During the laparotomy, a tumor at the upper anterior wall of gastric body was found and resected by a vertical gastrectomy. The pathological exam revealed hyperplastic smooth muscle fibers of the muscularis propria of the stomach wall, surrounded by hyaline stroma. The immunohistochemistry panel was positive for smooth muscle actin and type IV collagen, with low rate of mitosis studied by Ki-67 which allowed the final diagnosis of a gastric glomus tumor. Discussion. The majority of intraperitoneal glomus tumors occur in the stomach, and it is phenotypically similar to those localized in peripheral sites. Gastric GT generally is a benign tumor although it can be malignant and have the potential to metastasize. Conclusion. Even though gastric glomus tumor is rarely described, it should be considered as a possible cause of a major upper gastrointestinal bleeding

Surface Morphology Alterations In Bovine Dentin Exposed To Different Bleaching Agents

Aim: This study evaluated the morphological changes caused by internal bleaching agents on dentin surface. Methods: Twenty crowns of bovine incisors were cut into slabs that were randomly distributed in six experimental groups (n = 5), according to the bleaching agent used: G1 – sodium perborate + water, G2 – sodium perborate + 2% chlorhexidine gel, G3 – sodium perborate + 30% hydrogen peroxide, G4 – 30% hydrogen peroxide, G5 – 37% carbamide peroxide and G6 – gel base without carbamide. Two Control Groups were used: C1 with distilled water and C2 with 2% chlorhexidine gel. The specimens were immersed in the respective test bleaching agent and incubated at 37 °C for seven days. Following, they were prepared for scanning electron microscopy and five images from each tooth segment were recorded and analyzed for surface morphological alterations, by three previously calibrated examiners. Inter-examiner agreement was verified using the Kappa test. The rank averages obtained for the groups were subjected to Kruskal-Wallis analysis of variance at 5% significance level. Results: The analysis of the scores obtained indicated that all tested materials caused some morphological alteration on dentin, except for sodium perborate + water (G1) and Control Groups 1 and 2. Hydrogen peroxide and carbamide peroxide caused significantly more severe alterations (p < 0.05) to dentin structure, than the other bleaching agents evaluated. Conclusions: Sodium perborate-based pastes seemed to be the most harmless agent to dentin structures in non-vital tooth bleaching, while hydrogen peroxide solutions and carbamide peroxide agents caused the greatest alterations.8125-2

OS BENEFÍCIOS DO EXERCÍCIO FÍSICO DIANTE OS PRINCIPAIS TRANSTORNOS MENTAIS

A atividade física tem um papel importante na melhoria da autoestima, das funções cognitivas e da socialização, diminuindo também o estresse e a ansiedade. Por isso, a adoção de comportamentos saudáveis é o principal caminho para otimização e melhoria da saúde mental. Para discutir este tema, foi realizada uma revisão da literatura com busca pelos bancos de dados MEDLINE/PubMed, BIREME e LILACS de artigos relevantes sobre os benefícios do exercício físico sobre os principais transtornos mentais. Percebe-se que os benefícios da prática de atividade física regular, seja como forma de estímulo social, nos relacionamentos interpessoais ou na manutenção da saúde biológica dos indivíduos, especialmente, nos indivíduos portadores de transtornos mentais e psiquiátricos. Tais práticas são uma questão de saúde pública, e que necessita ser implantada no sistema de saúde, promovendo, por fim, a prevenção e cuidado integral ao ser humano

Comparing the efficacy of Xalatan and a similar latanoprost(Drenatan)in open angle glaucoma patients

AIM: To compare the monotheraphy efficacy of the brand latanoprost Xalatan and a similar latanoprost(Drenatan)regarding intraocular pressure(IOP)reduction in patients with primary open angle glaucoma(POAG).METHODS: Sixty two patients(119 eyes)were enrolled in this observational, retrospective study. In the first visit, the patient came in using the brand latanoprost(Xalatan)and it was changed to the similar latanoprost(Drenatan). In the second visit, 12wk later, a complete ophtalmologic exam including slit lamp examination, Goldmann applanation tonometry, stereoscopic fundus examination, gonioscopy, ultrasound pachymetry, automated visual field testing was performed.RESULTS:The mean IOP was 12.30±2.02mmHg and 12.38±2.05mmHg with using Xalatan and Drenatan, respectively. The P=0.559 demonstrates this relation. In fact, a correlation between the groups of R=0.987 points out the remarkable resemblance of both groups.CONCLUSION: Both Drenatan and Xalatan have similar efficacy in reducing IOP. Such finding is pivotal to public health to reduce cost and maintain its policies concerning drug efficacy and safety, this is especially significant in countries in which treatment cost is a barrier for patient adhesion to treatment

Volvulus of the Sigmoid Colon during Pregnancy: A Case Report

Colonic obstruction due to sigmoid colon volvulus during pregnancy is a rare but complication with significant maternal and fetal mortality. We describe a case of sigmoid volvulus in a patient with 33 weeks of gestation that developed complete necrosis of the left colon. Case. 27-year-old woman was admitted with 3 days of abdominal distention, vomit, and the stoppage of the passage of gases and feces. She was admitted with poor clinical conditions with septic shock, acute respiratory distress syndrome, and signs of diffuse peritonitis. Abdominal radiography showed severe dilation of the colon with horseshoe signal suggesting a sigmoid volvulus, pneumoperitoneum and we could not we could not identify fetal heartbeats. With a diagnosis of complicate sigmoid volvulus she was underwent to the laparotomy where we found necrosis of all descending colon due to double twist volvulus of the sigmoid. We performed a colectomy with a confection of a proximal colostomy, and closing of the rectal stump. Due to an uncontrollable uterine bleeding during cesarean due, it was required a hysterectomy. The patient had an uneventful postoperative course thereafter and was discharged on a regular diet on the 15th postoperative day
