RESUMO
Some chronic respiratory diseases can cause hypoxemia and, in such cases, long-term home oxygen therapy (LTOT) is indicated as a treatment option primarily to improve patient quality of life and life expectancy. Home oxygen has been used for more than 70 years, and support for LTOT is based on two studies from the 1980s that demonstrated that oxygen use improves survival in patients with COPD. There is evidence that LTOT has other beneficial effects such as improved cognitive function, improved exercise capacity, and reduced hospitalizations. LTOT is indicated in other respiratory diseases that cause hypoxemia, on the basis of the same criteria as those used for COPD. There has been an increase in the use of LTOT, probably because of increased life expectancy and a higher prevalence of chronic respiratory diseases, as well as greater availability of LTOT in the health care system. The first Brazilian Thoracic Association consensus statement on LTOT was published in 2000. Twenty-two years later, we present this updated version. This document is a nonsystematic review of the literature, conducted by pulmonologists who evaluated scientific evidence and international guidelines on LTOT in the various diseases that cause hypoxemia and in specific situations (i.e., exercise, sleep, and air travel). These recommendations, produced with a view to clinical practice, contain several charts with information on indications for LTOT, oxygen sources, accessories, strategies for improved efficiency and effectiveness, and recommendations for the safe use of LTOT, as well as a LTOT prescribing model.

Abstract Objectives: To detect RSV or other thirteen respiratory viruses as possible causer agent of bronchiolitis in infants. Method: This is an epidemiological analytical study, conducted using a nasopharyngeal aspirate of 173 hospitalized children younger than two years old with severe bronchiolitis in three hospitals in the Campinas Metropolitan Region (CMR) during 2013-14. The data was statically evaluated by Pearson's chi-squared test with statistical significance of 0.05 and 95% confidence level. Results: As expected, the most prevalent viruses detected were RSV A and B in 47% and 16% of the samples, respectively. However, almost a third of severe bronchiolitis cases there were no detection of RSV, and the viruses more commonly detected were rhinoviruses, which were identified in almost a quarter of all positive samples for at least a viral agent. Conclusions: Although nothing could be concluded from the disease severity and clinicalepidemiological data, the present study's results indicate that severe bronchiolitis is not always related to RSV infections in children younger than two years old, and the rhinoviruses were more prevalent in these cases. These findings reinforce the need to carry out a
RESUMO
The frequencies of 19 respiratory pathogens other than SARS-CoV-2 were assessed in 6,"?>235 Brazilian individuals tested for COVID-19. Overall, only 83 individuals who tested positive for SARS-CoV-2 had codetection of other pathogens. Individuals infected with Rhinovirus/Enterovirus, Human Coronavirus (HCoV)-HKU1, HCoV-NL63, HPIV-4, Influenza A (-H1N1 and other subtypes), Influenza B, Human Respiratory Syncytial Virus and Human Metapneumovirus were less likely to test positive for SARS-CoV-2. Infection with Streptococcys pyogenes, Chlamydophila pneumoniae, Mycoplasma pneumoniae, and Bordetella pertussis were more frequent in individuals who tested negative for SARS-CoV-2, but without significancy. We found 150 individuals infected with ≥2 pathogens other than SARS-CoV-2, only 3 out of whom tested positive for COVID-19. The codetection frequency was low in individuals diagnosed with COVID-19. Other viral infections may provide a cross-reactive, protective immune response against SARS-CoV-2. Screening for bacterial respiratory infections upon COVID-19 testing is important to drive suitable therapeutic approaches and avoid unnecessary antibiotic prescription.

RESUMO Algumas doenças respiratórias crônicas podem evoluir com hipoxemia e, nessas situações, a oxigenoterapia domiciliar prolongada (ODP) está indicada como opção terapêutica com o objetivo principal de melhorar a qualidade e a expectativa de vida desses pacientes. O oxigênio domiciliar é usado há mais de 70 anos, e a ODP tem como base dois estudos da década de oitenta que demonstraram que o uso de oxigênio melhora a sobrevida de pacientes com DPOC. Existem evidências de que a ODP tem outros efeitos benéficos como melhora da função cognitiva e da capacidade de exercício e redução de hospitalizações. A ODP está indicada para outras doenças respiratórias que cursam com hipoxemia, segundo os mesmos critérios estabelecidos para a DPOC. Tem sido observado aumento no uso da ODP provavelmente pela maior expectativa de vida, maior prevalência de doenças respiratórias crônicas e maior disponibilidade de ODP no sistema de saúde. O primeiro consenso sobre ODP da Sociedade Brasileira de Pneumologia e Tisiologia foi publicado em 2000; após 22 anos, apresentamos esta versão atualizada. Este documento é uma revisão não sistemática da literatura, realizada por pneumologistas que avaliaram evidências científicas e diretrizes internacionais sobre ODP nas diversas doenças que cursam com hipoxemia e em situações específicas (exercício, sono e viagens aéreas). Estas recomendações, tendo em vista a prática clínica, oferecem diversos quadros com informações sobre indicações, fontes de oxigênio, acessórios e estratégias para melhor eficiência, efetividade e uso seguro da ODP, assim como um modelo para sua prescrição.
RESUMO
Background: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract. It is exposed a clinical case of jejunal GIST from a second-level hospital in Mexico. Clinical case: Female patient of 76 years, with history of tobacco use (two cigarettes per day for 25 years), that is referred to General Surgery due to a four month evolution of symptoms, characterized by abdominal pain, hyporexia and urinary symptomatology. Physical examination revealed a non-pulsatile, solid, non-mobile, non-painful mass in the hypogastrium and right iliac fossa of approximately 15 cm in length. Ovarian tumor was ruled out, since CEA and CA-125 tumor markers were negative. Abdominopelvic ultrasound was performed and reported a solid tumor with cystic spaces inside. CT reported a solid tumor of 9.5 x 2.5 x 8.3 cm, with defined edges, multilobed, presence of some calcifications in its wall that did not show enhancement with the use of contrast media. Patient underwent exploratory laparotomy and it was found a jejunal tumor, 210 cm from the ligament of Treitz. Immunohistochemistry reported positivity to KIT and DOG1, confirming the diagnosis of GIST. Conclusion: GISTs are uncommon entities. Their clinical presentation is insidious and the preoperative diagnosis is complex due to the need for biopsy. The treatment is surgery, but tyrosine kinase inhibitors should be administered. Even in patients with response to treatment, follow-up is mandatory due to the risk of recurrence.
Introducción: los tumores del estroma gastrointestinal (GIST) son los tumores mesenquimatosos más comunes del tracto gastrointestinal. Se expone un caso clínico de GIST en yeyuno que se presentó en un hospital de segundo nivel en México. Caso clínico: femenino de 76 años, con antecedente de tabaquismo (dos cigarros diarios durante 25 años), referida a Cirugía General por cuadro de cuatro meses de evolución (dolor abdominal tipo cólico en hipogastrio, hiporexia y sintomatología urinaria). A la exploración física, se le detectó tumor no pulsátil, sólido, no móvil, no doloroso, adherido a planos profundos en hipogastrio y fosa ilíaca derecha de aprox. 15 cm de longitud. Se descartó tumor ovárico al resultar negativos los marcadores tumorales ACE y CA-125. Se realizó ultrasonido abdominopélvico que reportó imagen de tumoración sólida con zonas quísticas en su interior. La TC reportó tumoración sólida, de bordes definidos, multilobulada con algunas calcificaciones milimétricas en su pared de 9.5 x 2.5 x 8.3 cm y sin realce al administrar medio de contraste. La paciente se sometió a laparotomía exploradora y se encontró tumoración adherida a yeyuno a 210 cm del ligamento de Treitz. El tumor fue positivo a KIT y DOG1, lo que confirmó el diagnóstico de GIST de patrón fusiforme. Conclusión: los GIST son poco frecuentes. Su presentación clínica es insidiosa y el diagnóstico preoperatorio es complejo debido a la toma de biopsia. El tratamiento continúa siendo la cirugía, pero se deben administrar inhibidores de la tirosina cinasa. Incluso en pacientes con respuesta favorable al tratamiento, se recomienda seguimiento por riesgo de recidiva.

RESUMEN La producción científica sobre el término desarrollo se encuentra fragmentada a partir de intereses desarticuladores del capital. Este proceso ha desvirtuado las potencialidades de la sociedad para reencontrar lo comunitario como cualidad emancipadora del ser humano. La falta de unidad teórica y conceptual acerca del desarrollo ha sido tradicionalmente tratada por la sociología, la filosofía y la práctica política. Se plantea como objetivo identificar aspectos teóricos referidos a la cualidad comunitaria del desarrollo. El estudio tiene un enfoque marxista. Para la obtención de resultados, se emplean los métodos en el nivel teórico: analítico-sintético, sistémico-estructural, históricológico e inductivo-deductivo, y a nivel empírico, el análisis documental. Se enuncian consideraciones sobre el desarrollo desde una visión integradora que trasciende adjetivaciones y se fundamenta como un proceso real y concreto. Lo comunitario como cualidad transformadora de la actividad humana, concretado en los proyectos colectivos, constituye el principio teórico del desarrollo desalienador.
ABSTRACT The scientific production on the term development is found fragmented from disarticulating interests of capital. This process has distorted the potential of society to rediscover the community as an emancipating quality of the human being. The lack of theoretical and conceptual unity about development has traditionally been dealt with by sociology, philosophy and political practice. The objective is to identify theoretical aspects related to the community quality of development. The study has a Marxist approach. To obtain results, the methods are used at the theoretical level: analytic-synthetic, systemic-structural, historical-logical and inductive-deductive, and empirically, the documentary analysis. Considerations on development are enunciated from an integrating vision that transcends adjectives and is based on a real and concrete process. The community as a transforming quality of human activity, concretized in collective projects, constitutes the theoretical principle of disalienating development.

BACKGROUND: Each year, a considerable amount of children will experience at least one episode of acute viral bronchiolitis (AVB) during their first year of life. About 10% of them will be hospitalized, with significant physical and economic burdens. OBJECTIVES: To compare two cohorts of infants with AVB, from same region, in a ten-year interval, regarding epidemiologic factors and viral etiology. STUDY DESIGN: Cohorts: 142 (2004) and 172 (2014) infants at ages zero to 12 months; clinical diagnosis of AVB; medical care in hospital and genetic screening of nasopharyngeal secretion for respiratory viruses. RESULTS: The comparative analysis showed a difference in the percentage of respiratory syncytial virus (RSV) positive patients [2004 (33.1%); 2014 (70.3%)] (p<0.01). No differences were noted regarding gender, breastfeeding, tobacco exposure, crowding and maternal education. There was a difference as to the month of incidence (seasonality) of AVB (higher in April 2014). There was a higher age at attendance in the first cohort, and lower birth weight and gestational age ratios in the second cohort (p<0.05). There were no differences in hospitalization time, need of mechanical ventilation and number of deaths, however a difference regarding co-morbidities was noted (higher in 2004) (p<0.001). CONCLUSION: None of the analyzed variables had an impact on severity features. Virology and immunology must be considered in this kind of situation, by studying genetic variants and the maturation of the immune system in AVB by RSV or other viruses.

RESUMO
Resumen La aterosclerosis es una enfermedad que involucra múltiples mecanismos fisiopatológicos cuyo conocimiento no se ha dilucidado por completo. Con frecuencia, los avances científicos sobre la fisiopatología aterogénica generan que a diversas moléculas no consideradas previamente en el panorama de dicha enfermedad se les atribuyan acciones sobre el inicio o progresión de la misma. Un ejemplo representativo es el estudio de un nuevo mecanismo involucrado en el proceso aterogénico, consistente en la asociación entre el sistema de factores de crecimiento similares a la insulina (IGF) y la proteína plasmática A asociada al embarazo (PAPP-A). El sistema IGF es una familia de péptidos compuesto por 3 hormonas peptídicas, 4 receptores transmembranales y 6 proteínas transportadoras. El factor de crecimiento similar a la insulina tipo 1 (IGF-1) es el principal ligando del sistema IGF involucrado en la aterosclerosis coronaria y ejerce sus efectos mediante la activación del receptor IGF-1R en células de músculo liso vascular de las arterias coronarias o en macrófagos de placas ateroscleróticas. En células de músculo liso vascular promueve la migración y previene la apoptosis aumentando la estabilidad de la placa, y en macrófagos disminuye el transporte reverso de colesterol propiciando la formación de células espumosas. La regulación de la biodisponibilidad de IGF-1 en el endotelio se lleva a cabo por las proteasas de proteínas IGFBP, principalmente por la PAPP-A. En la presente revisión se abordan los mecanismos involucrados entre el sistema IGF y la PAPP-A en aterosclerosis coronaria con énfasis en los efectos moleculares producidos en células de músculo liso vascular y en macrófagos.
Abstract Atherosclerosis is a condition that involves multiple pathophysiological mechanisms and whose knowledge has not been fully elucidated. Often, scientific advances on the atherogenic pathophysiology generate that molecules not previously considered in the scene of this disease, were attributed actions on the onset or progression of it. A representative example is the study of a new mechanism involved in the atherogenic process, consisting of the association between the insulin-like growth factor (IGF) system and pregnancy-associated plasma protein-A (PAPP-A). Insulin-like growth factor system is a family of peptides that include 3 peptide hormones, 4 transmembrane receptors and 6 binding proteins. Insulin-like growth factor-1 (IGF-1) is the main ligand of the IGF system involved in coronary atherosclerosis. IGF-1 exerts its effects via activation of the IGF-1R receptor on vascular smooth muscle cells or macrophages. In vascular smooth muscle cells promotes migration and prevents apoptosis which increases plaque stability while in macrophages reduces reverse cholesterol transport leading to the formation of foam cells. Regulation of IGF-1 endothelial bioavailability is carried out by IGFBP proteases, mainly by PAPP-A. In this review, we address the mechanisms between IGF system and PAPP-A in atherosclerosis with emphasis on molecular effects on vascular smooth muscle cells and macrophages.

OBJECTIVE: to assess the epidemiological and genetic factors associated with severity of acute viral bronchiolitis (AVB) by respiratory syncytial virus (RSV). DATA SOURCE: the key words "bronchiolitis", "risk factor", "genetics" and "respiratory syncytial virus", and all combinations among them were used to perform a search in the PubMed, SciELO, and Lilacs databases, of articles published after the year 2000 that included individuals younger than 2 years of age. DATA SYNTHESIS: a total of 1,259 articles were found, and their respective summaries were read. Of these, 81 were selected, which assessed risk factors for the severity of AVB, and were read in full; the 60 most relevant studies were included. The epidemiologic factors associated with AVB severity by RSV were prematurity, passive smoking, young age, lack of breastfeeding, chronic lung disease, congenital heart disease, male gender, ethnicity, viral coinfection, low weight at admission, maternal smoking during pregnancy, atopic dermatitis, mechanical ventilation in the neonatal period, maternal history of atopy and/or asthma during pregnancy, season of birth, low socioeconomic status, Down syndrome, environmental pollution, living at an altitude > 2,500 meters above sea level, and cesarean section birth. Conversely, some children with severe AVB did not present any of these risk factors. In this regard, recent studies have verified the influence of genetic factors on the severity of AVB by RSV. Polymorphisms of the TLRs, RANTES, JUN, IFNA5, NOS2, CX3CR1, ILs, and VDR genes have been shown to be associated with more severe evolution of AVB by RSV. CONCLUSION: the severity of AVB by RSV is a phenomenon that depends on the varying degrees of interaction among epidemiological, environmental, and genetic variables.

BACKGROUND: Cervical and endometrial measurement in the gynecological and obstetric patients is of vital importance. There is no consensus for the correct way in which should be made the measurement, more than anything is for an opinion of some experts. OBJECTIVE: To determine whether there are differences in measurement of endometrial or sagittal cross section of the uterus and cervix in the measurement of fractional linear fashion or along the cervical canal. MATERIAL AND METHODS: Using a transvaginal ultrasound, was measured in a transverse and longitudinal endometrial lining. And by fractional measuring along the cervical canal and a linear manner from the internal to the external. RESULTS: We studied a total of 63 patients. The mean endometrial transversal measurement in a cross was 7.1. mm (SD +/- 3.3) The mean endometrial longitudinally measured were: 7.9 mm (SD +/- 3.4). The mean cervical measurement was fractionally 3.3 cm (SD +/- 0.4) Mean cervical linear measurement was 3.9 cm (SD +/- 0.4). Using student's t test where the value of p in the endometrial measurement was 0.0871 and p value in cervical measurement was 0.009, the latter being statistically significant. CONCLUSIONS: With respect to the measurement of the endometrial lining, there is no significant difference do any of the two different techniques. However, measurement of the cervix, another significant difference (p = 0.009), so it should be further investigated which of these two techniques is the right way to establish more accurate diagnoses.

BACKGROUND: To evaluate a method for treating uncorrected refractive error in adults in the developing world. DESIGN: Prospective, cross-sectional study in outpatient community health centres. PARTICIPANTS: Eight hundred and forty subjects aged 18 and older from rural villages in Haiti and Belize. METHODS: Undilated refractive error screening exams were conducted over a 5-day period in rural Haiti and Belize using portable autorefractors. Isometropic, spherical, ready-made spectacles were provided to patients with bilateral refractive error, astigmatism ≤ 1 dioptre in each eye and visual acuity worse than 6/9 in each eye. Visual acuity was measured with and without corrective spectacles. MAIN OUTCOME MEASURES: The mean visual improvement and median final visual acuity after treatment with ready-made glasses. RESULTS: Eight hundred and forty patients aged 18 and older were screened with autorefractors. One hundred and eighty-nine subjects (22.5%) were found to have visually significant bilateral refractive error. Fifty-eight per cent (110/189) of these patients met criteria for treatment with ready-made spectacles. Visual acuity improved an average of 4.2 lines in the better eye and 4.1 lines in the worse eye with corrective glasses. The median visual acuity in the better eye was 6/6 after treatment. CONCLUSION: Autorefractors and ready-made spectacles allow for effective treatment of uncorrected refractive error in adults in the developing world.

En el examen físico realizado se notó la salida de lágrimas con sangre muy fluida, por el ángulo externo del ojo izquierdo. La inyección intradérmica en la cara dorsal del muslo derecho de 0,1 mL de sangre autóloga, indujo una reacción equimótica dolorosa en el sitio de la inyección. La inyección de 0,1 mL de solución salina al 0,9 % como control en el muslo contralateral, resultó negativa. Sobre la base del examen clínico y estas pruebas, se concluyó como un Síndrome de Gardner-Diamond. Esta entidad debe ser considerada en el diagnóstico diferencial de un síndrome purpúrico de etiología no bien precisada, fundamentalmente en pacientes con problemas psiquiátricos.
This is the case of a white woman aged 44, admitted in the Internal Medicine Service of "Miguel Enríquez" Clinical Surgical Hospital due to acute febrile syndrome and hematuria. At physical examination performed we noted a very high level of watering with presence of blood by left angle of left eye. The intradermal injection of 0,1 ml of autologous blood in dorsal part of right thigh, induced a painful ecchymotic reaction in injection site. The injection of 0.1 ml of 0,9% saline solution as control in contralateral thigh was negative. On the base of clinical examination and these tests, we conclude that it was a Gardner-Diamond syndrome. This entity must to be considered in differential diagnosis of a purpuric syndrome of a non-well established etiology, mainly in patients presenting with psychiatric disorders.

PURPOSE: To document etiology and predictive value of clinical diagnosis in laboratory confirmed viral diseases. METHODS: Reports of culture-positive cases of samples collected from patients presenting from January 1987 - December 2001 were evaluated. RESULTS: One thousand nine hundred and sixty-four (1964) cultures were submitted during 1987-2001. Twenty-six percent were positive (514). Human herpesvirus 1 was the most frequent agent isolated from all positive culture (56%). Adenovirus was the most common virus isolated from conjunctiva (66%), human herpesvirus 1 from lid and cornea (76%, 88%) and cytomegalovirus from vitreous (27%). Some unusual pathogens were recovered from conjunctiva as cytomegalovirus and from cornea as adenovirus, enterovirus and cytomegalovirus. Recognition of common viral syndromes was human herpesvirus 1 (88%), epidemic keratoconjunctivitis (88%), acute hemorrhagic conjunctivitis (70%) and varicella zoster virus (100%). However, some misdiagnosed cases were observed. Thirteen percent of conjunctivitis thought to be caused by herpes were due to adenovirus, 3.2% to Enterovirus, 3.2% to varicella zoster virus and 3.2% to human cytomegalovirus. Also, 5% of cases with a clinical diagnosis of herpes keratitis were caused by adenovirus and 2.7% by enterovirus. Finally, 4.8% of cases thought to be adenovirus conjunctivitis were herpes conjunctivitis. CONCLUSIONS: Human herpesvirus 1 remains the most frequently isolated virus from ocular sites in general (56%). Nonherpetic corneal isolates were in decreasing order: adenovirus, enterovirus and cytomegalovirus. Clinical and laboratory correlation was less than 90%. The most misdiagnosed cases were herpes conjunctivitis and keratitis, some cases of adenovirus conjunctivitis some cases of acute hemorrhagic conjunctivitis. It is essential that a rapid and specific diagnosis is offered under atypical viral presentation for the institution of specific antiviral therapy and to avoid complications that can be a result of misdiagnosis and inappropriate treatment. Also it is important to do viral testing in order to confirm clinical diagnosis, report emerging infections, resistance and change in the epidemiology.

OBJETIVOS: Documentar a etiologia e prever a importância do diagnóstico clínico em doenças virais oculares confirmadas em laboratório. MÉTODOS: Todos os relatórios de pacientes com cultura viral positiva durante o período de janeiro 1987 - dezembro 2001 foram analisados. RESULTADOS: Quinhentos e quatorze (514) casos foram encontrados. Em geral, herpesvírus 1 humano foi o agente mais freqüentemente isolado. Adenovírus foi o vírus mais comumente isolado da conjuntiva (66 por cento), herpesvírus 1 humano das pálpebras e córnea (76 por cento, 88 por cento respectivamente) e citomegalovírus do vítreo (27 por cento). Alguns agentes não usuais foram isolados da conjuntiva como citomegalovírus e da córnea como adenovírus, enterovírus e citomegalovírus. Reconhecimento das síndromes virais comuns foi: herpervírus 1 humano (88 por cento), ceratoconjuntivite epidêmica (88 por cento), conjuntivite aguda hemorrágica (70 por cento). Porém, alguns casos com diagnóstico incorreto foram observados. Treze por cento das conjuntivites com diagnóstico de herpes foram causadas por adenovírus, 3,2 por cento por enterovírus, 3,2 por cento por varicella zoster vírus e 3,2 por cento por citomegalovírus. Também, 5 por cento dos casos com diagnóstico clínico de ceratite herpética eram adenovírus e 2,7 por cento enterovírus. Além disso, 4,8 por cento dos casos em que se pensaram em conjuntivite por adenovírus, eram conjuntivite por herpes. Finalmente, 30 por cento dos casos em que se diagnosticaram conjuntive hemorrágica aguda, o agente etiológico era adenovírus. CONCLUSÃO: Em geral herpesvírus humano 1 continua a ser o vírus mais comum encontrado nas infecções oculares (56 por cento). Agentes não herpéticos isolados da córnea foram em ordem decrescente: adenovírus, enterovírus e citomegalovírus. A correlação entre o diagnóstico clínico e laboratorial foi menor do que 90 por cento. Um diagnóstico rápido e específico é essencial em casos de apresentações virais atípicas...
