Oral health in Brazil - Part II: Dental Specialty Centers (CEOs)

The concepts of health promotion, self-care and community participation emerged during the 1970s and, since then, their application has grown rapidly in the developed world, showing evidence of effectiveness. In spite of this, a major part of the population in the developing countries still has no access to specialized dental care such as endodontic treatment, dental care for patients with special needs, minor oral surgery, periodontal treatment and oral diagnosis. This review focuses on a program of the Brazilian Federal Government named CEOs (Dental Specialty Centers), which is an attempt to solve the dental care deficit of a population that is suffering from oral diseases and whose oral health care needs have not been addressed by the regular programs offered by the SUS (Unified National Health System). Literature published from 2000 to the present day, using electronic searches by Medline, Scielo, Google and hand-searching was considered. The descriptors used were Brazil, Oral health, Health policy, Health programs, and Dental Specialty Centers. There are currently 640 CEOs in Brazil, distributed in 545 municipal districts, carrying out dental procedures with major complexity. Based on this data, it was possible to conclude that public actions on oral health must involve both preventive and curative procedures aiming to minimize the oral health distortions still prevailing in developing countries like Brazil

Investigação da trombose venosa na gravidez Deep vein thrombosis during pregnancy work up

CONTEXTO: A trombose venosa profunda (TVP) na gravidez é fator determinante no aumento da morbidade e da mortalidade maternofetal. Pode ocorrer na presença de trombofilias, por compressão da veia cava inferior, estase venosa ou alterações hormonais. OBJETIVOS: Analisar pacientes grávidas e no pós-parto imediato portadoras de TVP em membros inferiores, pesquisar as possíveis causas de trombofilia e realizar revisão de literatura. MÉTODOS: Foram analisadas gestantes e puérperas encaminhadas por ginecologistas e obstetras com quadro clínico suspeito de TVP, de janeiro de 2004 a novembro de 2006, período em que foram realizados 24.437 partos no Hospital e Maternidade São Luiz (HMSL), sendo 89% cesarianas, 7,5% partos normais e 3,5% fórceps. Do total de pacientes encaminhadas com quadro clínico sugestivo, foram realizados 42 diagnósticos clínicos de TVP em gestantes com idade entre 21 e 39 anos, confirmados por duplex scan venoso. Imediatamente antes da introdução da terapia anticoagulante, foram colhidos exames para pesquisa de trombofilia, os quais foram repetidos após o período de tratamento. RESULTADOS: Das 42 pacientes portadoras de TVP, 32 eram primigestas (três gemelares sem alterações trombofílicas, duas por fecundação in vitro), oito secundigestas e duas tercigestas. Em quatro pacientes, a TVP ocorreu no primeiro trimestre da gestação (9,5%); em 11, no segundo trimestre (26,2%); em 27, no terceiro trimestre (64,3%). Dos 42 casos de diagnóstico de TVP, 18 (42,8%) ocorreram nas veias infrapatelares. Houve um caso de tromboembolismo pulmonar (TEP) em paciente de 37 anos que havia realizado fecundação in vitro, com gestação gemelar, e TVP (ausência de trombofilia) diagnosticada após a cesariana. Das 42 pacientes, 16 (38,1%) tiveram a causa da TVP estabelecida, com prevalência de mutação heterozigótica do fator V de Leiden (FVL) em seis pacientes (14,2%), seguida pela síndrome antifosfolípide e outras. A maioria das pacientes foi tratada com heparina de baixo peso molecular. CONCLUSÃO: A TVP na gravidez, apesar de sua baixa freqüência, aumenta consideravelmente a morbidade maternofetal. A pesquisa de trombofilia deve ser realizada em casos selecionados, tais como antecedentes pessoais ou familiares de fenômenos trombóticos e/ou trombofilia. A gestação gemelar, a cesariana e a inseminação artificial também foram fatores predisponentes para a ocorrência de TVP.<br>BACKGROUND: Deep venous thrombosis (DVT) during pregnancy is a determining factor that contributes to increased maternal-fetal morbidity and mortality. It may occur when there is thrombophilia, due to compression of the inferior vena cava, venous stasis or hormonal changes. OBJECTIVES: To assess patients who are pregnant or have just given birth and who have a DVT condition in the lower limbs, to search for possible causes of thrombophilia and to perform a review of the literature. METHODS: Pregnant and puerperal patients were assessed by gynecologists and obstetricians when there was suspicion of DVT, from January 2004 through November 2006, during which time there were 24,437 childbirths at Hospital e Maternidade São Luiz; of these, 89% were cesarean, 7.5% were normal births and 3.5% were forceps deliveries. Of the total number of patients referred with a clinical status suggesting DVT, 42 cases were clinically diagnosed as DVT, in pregnant women aged between 21-39 years, confirmed by venous duplex scan. Right before the introduction of anticoagulant therapy, samples were collected to investigate thrombophilia, which were repeated after the treatment. RESULTS: Of the 42 patients with DVT, 32 were primigravid (three twin pregnancies with no thrombophilic changes, two resulting from in vitro fecundation), eight were mothers at second birth and two were at third birth. In four patients, DVT occurred in the first trimester of pregnancy (9.5%), in 11 patients DVT was present in the second trimester (26.2%) and in 27 patients the disease developed in the third trimester of pregnancy (64.3%). Of the 42 patients diagnosed with DVT, 18 (42.8%) occurred in infrapatellar veins. There was a case of pulmonary thromboembolism in a 37-year-old patient, who had been submitted to in vitro fecundation, with twin pregnancy and a diagnostic of DVT (no thrombophilia) after a cesarean section. Of the 42 patients, 16 (38.1%) had the cause of their DVT determined, with a prevalence of heterozygous mutation of factor V Leiden in six patients (14.2%), followed by phospholipid syndrome and other causes. Most patients were treated with low-molecular-weight heparin. CONCLUSION: DVT during pregnancy, despite having low frequency, is a major cause of increased maternal-fetal morbidity. Investigation of thrombophilia should be conducted in selected cases, such as personal or family history of thrombotic phenomena and/or thrombophilia. Twin pregnancy, cesarean birth and artificial insemination were also found as factors leading to DVT

Relação entre perdas dentárias e queixas de mastigação, deglutição e fala em indivíduos adultos Relation between tooth loss and chewing, swallowing and speech complaints in adults

OBJETIVO: investigar se as perdas dentárias em indivíduos adultos apresentam relação com as queixas de fala, mastigação e deglutição. MÉTODOS: participaram deste estudo 50 indivíduos adultos, trabalhadores de uma Avícola, do município de Bariri (SP), com faixa etária entre 18 e 52 anos. Os participantes selecionados foram submetidos à avaliação odontológica por um cirurgião-dentista e à entrevista fonoaudiológica, por duas fonoaudiólogas, em um consultório do município que mantém contrato de prestação de serviço com a Avícola. Para análise dos resultados, foram comparados os indivíduos com e sem perda dos elementos dentários, denominados de grupo experimental (GE) e grupo controle (GC), respectivamente, a partir da aplicação do teste Qui-Quadrado. RESULTADOS: os resultados revelaram maior ocorrência de mastigação unilateral no GE. Queixas quanto à dificuldade e dor na mastigação estiveram presentes apenas no GE, com diferença estatisticamente significante entre os grupos (p<0,05). O tempo de deglutição mostrou-se inadequado para a maioria dos indivíduos em ambos os grupos. A maioria dos indivíduos do GC mencionou utilizar algum tipo de líquido para facilitar a deglutição. Nenhum indivíduo mencionou queixas de fala. CONCLUSÃO: os achados revelaram que a ausência de elementos dentários em indivíduos adultos apresentou relação apenas entre dificuldade e dor durante a mastigação.<br>PURPOSE: to investigate if tooth absence in adults shows any relationship with chewing, swallowing and speech complaints. METHODS: 50 adults, who were poultry farm workers from Bariri municipality, in the State of São Paulo, Brazil, between the ages of 18 and 52, took part in this study. The selected participants were evaluated by a dentist and interview were carried out by two speech and language pathologist, in one of the municipality's office which has a contract of service rendering with the poultry farm. For analyzing the results, individuals with and without tooth loss, referred to as, respectively, the experimental group (EG) and the control group (CG), and were compared based on the performance of the Chi-Square test. RESULTS: the results revealed a higher occurrence of unilateral chewing in the EG (61.54%) and the chewing time showed itself inadequate for the most of the individuals in both groups. Claims of difficulties and pain in chewing were present only in the EG, which showed a statistically significant difference (p<0.05). Most of the individuals of the CG also mentioned the use of some drinking liquids to facilitate swallowing, without a statistically significant difference. There was no report of complaints related to speech in both groups. CONCLUSION: the findings revealed that the absence of teeth in adults showed relation only with the complaints with difficulty and pain during chewing
