Cone rod dystrophies

Cone rod dystrophies (CRDs) (prevalence 1/40,000) are inherited retinal dystrophies that belong to the group of pigmentary retinopathies. CRDs are characterized by retinal pigment deposits visible on fundus examination, predominantly localized to the macular region. In contrast to typical retinitis pigmentosa (RP), also called the rod cone dystrophies (RCDs) resulting from the primary loss in rod photoreceptors and later followed by the secondary loss in cone photoreceptors, CRDs reflect the opposite sequence of events. CRD is characterized by primary cone involvement, or, sometimes, by concomitant loss of both cones and rods that explains the predominant symptoms of CRDs: decreased visual acuity, color vision defects, photoaversion and decreased sensitivity in the central visual field, later followed by progressive loss in peripheral vision and night blindness. The clinical course of CRDs is generally more severe and rapid than that of RCDs, leading to earlier legal blindness and disability. At end stage, however, CRDs do not differ from RCDs. CRDs are most frequently non syndromic, but they may also be part of several syndromes, such as Bardet Biedl syndrome and Spinocerebellar Ataxia Type 7 (SCA7). Non syndromic CRDs are genetically heterogeneous (ten cloned genes and three loci have been identified so far). The four major causative genes involved in the pathogenesis of CRDs are ABCA4 (which causes Stargardt disease and also 30 to 60% of autosomal recessive CRDs), CRX and GUCY2D (which are responsible for many reported cases of autosomal dominant CRDs), and RPGR (which causes about 2/3 of X-linked RP and also an undetermined percentage of X-linked CRDs). It is likely that highly deleterious mutations in genes that otherwise cause RP or macular dystrophy may also lead to CRDs. The diagnosis of CRDs is based on clinical history, fundus examination and electroretinogram. Molecular diagnosis can be made for some genes, genetic counseling is always advised. Currently, there is no therapy that stops the evolution of the disease or restores the vision, and the visual prognosis is poor. Management aims at slowing down the degenerative process, treating the complications and helping patients to cope with the social and psychological impact of blindness

Global patient outcomes after elective surgery: prospective cohort study in 27 low-, middle- and high-income countries.

BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

Treinamento da equipe de saúde e busca ativa na comunidade: estratégias para a detecção de casos de TB Health team training and active community surveillance: strategies for the detection of TB cases

OBJETIVO: Avaliar o impacto do treinamento da equipe do Programa Saúde da Família (PSF) e da busca ativa domiciliar na detecção de casos de TB em uma comunidade de baixa renda de Fortaleza. MÉTODOS: Intervenção realizada na área de abrangência de um centro de saúde de Fortaleza, Ceará, com cinco equipes do PSF, responsáveis por cerca de 25.000 pessoas. Treinaram-se todas as equipes de saúde do centro de saúde e implantou-se a busca ativa domiciliar apenas na área de abrangência da Equipe 5. Comparou-se o número de casos detectados em cada uma das cinco áreas antes e depois da intervenção, bem como os casos na área 5 com os das outras áreas e com os casos notificados no município de Fortaleza durante o mesmo período. RESULTADOS: Observou-se um aumento no número de casos de TB detectados na área do estudo: de 1 caso em 2002 para 22 em 2004 (p < 0,005), sem diferença entre a área em que foi feita a busca domiciliar e as outras quatro (p > 0,05). Houve um aumento significativo no número de casos detectados na área do estudo em comparação com aquele no município como um todo (p < 0,05). CONCLUSÕES: O treinamento e a sensibilização da equipe de saúde da família foram capazes de promover um aumento na detecção de casos de TB em uma comunidade de baixa renda.<br>OBJECTIVE:To evaluate the impact that Family Health Program (FHP) team training and active surveillance have on the detection of TB cases in a low-income community in the city of Fortaleza, Brazil. METHODS: The study was performed in an area with approximately 25,000 inhabitants, served by a health care center with five FHP teams, in the city of Fortaleza, Brazil. Although all of the teams were trained, active surveillance was carried out only in one of the areas (area 5). We compared the number of TB cases detected in each of the five areas prior to and after the intervention. We also compared the number of TB cases detected in area 5 to the number of those detected in the other areas, as well as to the citywide number of reported TB cases in Fortaleza, within the same period. RESULTS: The number of TB cases detected in the area studied increased from 1 in 2002 to 22 in 2004 (p < 0.05). There was no significant difference between the number of TB cases in area 5 and that observed for each of the other four areas (p > 0.05). There was a significant increase in the number of TB cases detected in the area studied when compared to the city as a whole (p < 0.05). CONCLUSIONS: Training and sensitization of FHP professionals were effective in promoting an increase in the number of TB cases detected in a low-income community

The profile of professionals in health and education fields at work in their communities Perfil de profissionais nas áreas de saúde e educação atuando em suas comunidades

Social roles mold attitudes of actors who play the part in the community, and affect behavioral and moral attitudes and social conscience. There is a diversity of behaviors that demonstrates the extension to which individuals are in constant participation in the community life. A group profile of professional's health and education may supply information on the disciplinary approach in Community Health. Objective: to examine the profile of professionals at work in the Health and Education fields. Subjects participated in answering questions concerning professional work, leisure/religious activities, feeding/sleep habits, prevention and contraceptive methods, medical and/or psychological treatment and medicine/herbal use. Characteristics of the professional group regarding life style and the paradox of the practice of safe sex behavior were recorded. There exists the possibility to improve the quality of life for people in communities by reducing the sources of stress and tension by promoting physical and mental health. Methods should be investigated to allow for the promotion of a quality of life in a small fraction of the population engaged in health and education work in their own communities.<br>Papéis sociais moldam as atitudes dos atores que participam na comunidade e afetam as atitudes comportamentais, morais e a consciência social. Há uma diversidade de comportamentos que demonstra a extensão em que os indivíduos estão em constante participação na vida da comunidade. O perfil de um grupo de profissionais em saúde e educação poderia fornecer informação disciplinar sobre a saúde da comunidade. Objetivo: examinar o perfil de profissionais da saúde e da educação. Os sujeitos participaram respondendo questões sobre trabalho profissional, atividades de lazer e religiosas, hábitos de alimentação e sono, métodos de prevenção e de contracepção, tratamento médico e/ou psicológico e uso de medicamentos/plantas medicinais. Observaram-se características do grupo de profissionais relacionadas com o estilo de vida e também o paradoxo do comportamento quanto à prática de sexo seguro. Existem condições de vida para as pessoas melhorarem suas comunidades, reduzindo fontes de estresse e tensão e promovendo saúde física e mental. Métodos poderiam ser investigados para tornar possível a promoção da qualidade de vida de uma pequena fração da população engajada no trabalho em saúde e educação em suas próprias comunidades
