RESUMO
BACKGROUND: According to international diagnostic guidelines for hypersensitivity pneumonitis (HP), cases with both nonfibrotic and fibrotic lesions are classified by the predominant feature. Therefore, some cases with nonfibrotic HP, have inflammatory lesions alone, while others have a mixture of fibrosis and inflammation. We investigated the impact of slight fibrotic lesions in nonfibrotic HP. METHODS: This retrospective study included nonfibrotic HP cases with <10% of lung distortion on high-resolution CT. We divided the cases into two groups: those with pure ground glass opacities (GGOs) without lung distortion and those with slight lung distortion of <10%. RESULTS: In this study, 37 cases were included. The mean baseline forced vital capacity (FVC) was 109% in the pure GGO group and 96% in the slight lung distortion group (p = 0.038). After 1 year, the reticular shadows appeared or increased more in the slight lung distortion group than in the pure GGO group (16% vs. 8%, p = 0.030). The time to medication initiation was significantly shorter in the slight lung distortion group than in the pure GGO group (p = 0.044). %FVC decreased by ≥ 5% from diagnosis in no cases with the pure GGO and in two cases with the slight lung distortion (-11.0% for 9.5 years and -10.7% for 1.3 years, respectively). CONCLUSIONS: The slight distortion group exhibited a higher rate of worsening and new appearance of reticular shadows after 1 year and a shorter time to first medication compared to the pure GGO group.
RESUMO
BACKGROUND: The role of radiology in the diagnosis of interstitial lung diseases (ILDs) has evolved over time, in part replacing histology. Radiology now represents a pillar of diagnostics and monitoring in ILDs. OBJECTIVE: To what extent does radiology influence diagnostics and treatment in ILDs? MATERIALS AND METHODS: A literature review was conducted, and current findings were discussed in the context of clinical data. RESULTS: Radiology plays a crucial role in the diagnosis of ILDs. Within the framework of the multidisciplinary conference, it provides specific CT patterns such as usual interstitial pneumonia (UIP), nonspecific interstitial pneumonia (NSIP), and organizing pneumonia (OP), or helps in identifying cystic lung diseases. Multicompartment diseases can be detected, and pulmonary hypertension or extrapulmonary involvement of the respective diseases can be suspected. Progressive pulmonary fibrosis requires radiologic assessment as one of the required criteria. Interstitial lung abnormalities are usually detected by radiological studies performed for an unrelated indication. CONCLUSION: Radiology plays an important role within the multidisciplinary conference to determine both diagnosis and treatment with antifibrotic or anti-inflammatory drugs, or a combination of both.

Hypersensitivity pneumonitis (HP) is a pulmonary disease characterized by inflammation and fibrosis of the lung parenchyma following chronic exposure to immunogenic antigens. The pathophysiology of HP involves type 3 and type 4 hypersensitivity reactions leading to acute and chronic manifestations, respectively. Clinically, it manifests as exertional dyspnea and wheezing. Pulmonary function tests display a pattern of restrictive lung disease, and high-resolution CT scans display a pattern of ground glass opacities, centrilobular nodules, and mosaic attenuation. Antigen avoidance remains the only method for primary prevention. Alternative therapy may be needed due to either the inability to avoid antigens or the lack of antigen identification. Prednisone 0.5 mg/kg per day is the first-line treatment for acute non-fibrotic forms of HP. In chronic or fibrotic HP, the immunomodulator mycophenolate mofetil (MMF) was shown to be an effective treatment in improving the diffusing capacity of the lungs for carbon monoxide and forced vital capacity, but not overall survival. The following study aims to bring to attention the need for additional prospective multicenter clinical trials to clarify the role of MMF as an immunomodulator in fibrosing HP.
RESUMO
Pulmonary Mycobacterium tuberculosis (Mtb) infection results in highly heterogeneous lesions ranging from granulomas with central necrosis to those primarily comprised of alveolitis. While alveolitis has been associated with prior immunity in human post-mortem studies, the drivers of these distinct pathologic outcomes are poorly understood. Here, we show that these divergent lesion structures can be modeled in C3HeB/FeJ mice and are regulated by prior immunity. Using quantitative imaging, scRNAseq, and flow cytometry, we demonstrate that Mtb infection in the absence of prior immunity elicits dysregulated neutrophil recruitment and necrotic granulomas. In contrast, prior immunity induces rapid recruitment and activation of T cells, local macrophage activation, and diminished late neutrophil responses. Depletion studies at distinct infection stages demonstrated that neutrophils are required for early necrosis initiation and necrosis propagation at chronic stages, whereas early CD4 T cell responses prevent neutrophil feedforward circuits and necrosis. Together, these studies reveal fundamental determinants of tuberculosis lesion structure and pathogenesis, which have important implications for new strategies to prevent or treat tuberculosis.
RESUMO
El objetivo de este estudio fue investigar el rol de la clorhexidina en sus diferentes formatos en la prevención de la alveolitis seca posterior a la extracción dental. Se realizó una búsqueda electrónica en las bases de datos de PubMed, Scopus, Web of Science. hasta el año 2021. Dos revisores de forma independiente realizaron el análisis de los artículos. La búsqueda inicial dio como resultado 192 artículos. Se descartaron 59 artículos duplicados y se realizó una revisión general inicial de títulos y resúmenes, verificando que se cumplan los criterios de inclusión y exclusión preestablecidos. De 192 estudios, 25 cumplieron con los criterios de inclusión. De los 25 artículos, 10 incluyeron pacientes con factores de riesgo asociados a alveolitis seca. Respecto al sitio de extracción dental, 19 artículos incluyeron pacientes con terceros molares mandibulares. Dentro de los artículos filtrados se utilizaron tres formatos de clorhexidina: enjuague, gel bioadhesivo e irrigante; estos en diferentes concentraciones, y comparadas con distintos grupos placebos. De los estudios incluidos, 18 informaron que la clorhexidina en sus diferentes formatos proporcionaba disminución en la incidencia de alveolitis seca versus el grupo control. El uso de clorhexidina en sus diferentes formatos después de la extracción dental es altamente efectivo en la prevención de la alveolitis seca. Sin embargo, inferimos que se necesitan nuevas líneas investigativas que incluyan pacientes con factores de riesgo asociados, y estudios que no utilicen terapias complementarias, puesto que, estos factores pueden conducir a confusión en los resultados obtenidos.
The objective of this study was to investigate the role of chlorhexidine in its different formats in the prevention of dry socket after dental extraction. The electronic search was performed using keywords and MeSH terms in the databases of PubMed, Scopus, Web of Science, until 2021. The reviewers independently performed the analysis of the articles. The initial search resulted in 192 articles. 59 duplicate articles were discarded, and an initial general review of titles and abstracts was performed, verifying that the pre-established inclusion and exclusion criteria were met. Of 192 studies, 25 met the inclusion criteria. Of the 25 articles, 10 included patients with risk factors associated with dry socket. Regarding the site of dental extraction, 19 articles included patients with mandibular third molars. Within the filtered articles, three formats of chlorhexidine were used: rinse, bioadhesive gel and irrigant, in different concentrations, and compared with different placebo groups. Of the included studies, 18 reported that chlorhexidine in its different formats provided a decrease in the incidence of dry socket versus the control group. The use of chlorhexidine in its different formats after dental extraction, is highly effective in preventing dry socket. However, we infer that new research lines are needed that include patients with associated risk factors, and studies that do not use complementary therapies.
RESUMO
ABSTRACT Objective: To assess the relative frequency of incident cases of interstitial lung diseases (ILDs) in Brazil. Methods: This was a retrospective survey of new cases of ILD in six referral centers between January of 2013 and January of 2020. The diagnosis of ILD followed the criteria suggested by international bodies or was made through multidisciplinary discussion (MDD). The condition was characterized as unclassifiable ILD when there was no specific final diagnosis following MDD or when there was disagreement between clinical, radiological, or histological data. Results: The sample comprised 1,406 patients (mean age = 61 ± 14 years), and 764 (54%) were female. Of the 747 cases exposed to hypersensitivity pneumonitis (HP)-related antigens, 327 (44%) had a final diagnosis of HP. A family history of ILD was reported in 8% of cases. HRCT findings were indicative of fibrosis in 74% of cases, including honeycombing, in 21%. Relevant autoantibodies were detected in 33% of cases. Transbronchial biopsy was performed in 23% of patients, and surgical lung biopsy, in 17%. The final diagnoses were: connective tissue disease-associated ILD (in 27%), HP (in 23%), idiopathic pulmonary fibrosis (in 14%), unclassifiable ILD (in 10%), and sarcoidosis (in 6%). Diagnoses varied significantly among centers (c2 = 312.4; p < 0.001). Conclusions: Our findings show that connective tissue disease-associated ILD is the most common ILD in Brazil, followed by HP. These results highlight the need for close collaboration between pulmonologists and rheumatologists, the importance of detailed questioning of patients in regard with potential exposure to antigens, and the need for public health campaigns to stress the importance of avoiding such exposure.
RESUMO Objetivo: Avaliar a frequência relativa de casos incidentes de doenças pulmonares intersticiais (DPI) no Brasil. Métodos: Levantamento retrospectivo de casos novos de DPI em seis centros de referência entre janeiro de 2013 e janeiro de 2020. O diagnóstico de DPI seguiu os critérios sugeridos por órgãos internacionais ou foi feito por meio de discussão multidisciplinar (DMD). A condição foi caracterizada como DPI não classificável quando não houve um diagnóstico final específico após a DMD ou houve discordância entre dados clínicos, radiológicos ou histológicos. Resultados: A amostra foi composta por 1.406 pacientes (média de idade = 61 ± 14 anos), sendo 764 (54%) do sexo feminino. Dos 747 casos expostos a antígenos para pneumonite de hipersensibilidade (PH), 327 (44%) tiveram diagnóstico final de PH. Houve relato de história familiar de DPI em 8% dos casos. Os achados de TCAR foram indicativos de fibrose em 74% dos casos, incluindo faveolamento, em 21%. Autoanticorpos relevantes foram detectados em 33% dos casos. Biópsia transbrônquica foi realizada em 23% dos pacientes, e biópsia pulmonar cirúrgica, em 17%. Os diagnósticos finais foram: DPI associada à doença do tecido conjuntivo (em 27%), PH (em 23%), fibrose pulmonar idiopática (em 14%), DPI não classificável (em 10%) e sarcoidose (em 6%). Os diagnósticos variaram significativamente entre os centros (c2 = 312,4; p < 0,001). Conclusões: Nossos achados mostram que DPI associada à doença do tecido conjuntivo é a DPI mais comum no Brasil, seguida pela PH. Esses resultados destacam a necessidade de uma estreita colaboração entre pneumologistas e reumatologistas, a importância de fazer perguntas detalhadas aos pacientes a respeito da potencial exposição a antígenos e a necessidade de campanhas de saúde pública destinadas a enfatizar a importância de evitar essa exposição.
RESUMO
La enfermedad pulmonar intersticial difusa (EPID) supone un amplio grupo heterogéneo de enfermedades caracterizadas por hallazgos en su intersticio pulmonar, específicamente relacionados con su engrosamiento, lo cual impacta significativamente en el intercambio gaseoso y la mecánica ventilatoria del paciente. El diagnóstico se genera acorde a la clínica del paciente, el uso de imágenes y la histopatología. El tratamiento guarda relación directa con el patrón pulmonar estructural que presente la EPID. Se presenta el caso clínico de una paciente femenina de 32 años, indígena, quien ingresa por exacerbación de disnea, con antecedente de neumonitis por hipersensibilidad, adicional a otros antecedentes clínicos que guardan relación estrecha con la EPID.
Diffuse interstitial lung disease (ILD) is a large heterogeneous group of diseases characterized by findings in the pulmonary interstitium, specifically changes related to thickening of the interstitium, which significantly impacts the patient's gas exchange and ventilatory mechanics. The diagnosis is generated according to the patient's clinical presentation, imaging and histopathology. The treatment is directly related to the structural pulmonary pattern of ILD. We present the clinical case of a 33-year-old female patient of indigenous ethnicity who is admitted for exacerbation of dyspnea, with a history of hypersensitivity pneumonitis in addition to other clinical antecedents that are closely related to ILD.

ABSTRACT Objective: To compare patients with chronic hypersensitivity pneumonitis (cHP) and controls with normal spirometry in terms of their sleep characteristics, as well as to establish the prevalence of obstructive sleep apnea (OSA) and nocturnal hypoxemia. Secondary objectives were to identify factors associated with OSA and nocturnal hypoxemia; to correlate nocturnal hypoxemia with the apnea-hypopnea index (AHI) and lung function, as well as with resting SpO2, awake SpO2, and SpO2 during exercise; and to evaluate the discriminatory power of sleep questionnaires to predict OSA. Methods: A total of 40 patients with cHP (cases) were matched for sex, age, and BMI with 80 controls, the ratio of controls to cases therefore being = 2:1. The STOP-Bang questionnaire, the Epworth Sleepiness Scale (ESS), the Pittsburgh Sleep Quality Index, the Berlin questionnaire and the Neck circumference, obesity, Snoring, Age, and Sex (NoSAS) score were applied to all cases, and both groups underwent full-night polysomnography. Results: The patients with cHP had longer sleep latency, lower sleep efficiency, a lower AHI, a lower respiratory disturbance index, fewer central apneas, fewer mixed apneas, and fewer hypopneas than did the controls. The patients with cHP had significantly lower nocturnal SpO2 values, the percentage of total sleep time spent below an SpO2 of 90% being higher than in controls (median = 4.2; IQR, 0.4-32.1 vs. median = 1.0; IQR, 0.1-5.8; p = 0.01). There were no significant differences between cases with and without OSA regarding the STOP-Bang questionnaire, NoSAS, and ESS scores. Conclusions: The prevalence of OSA in cHP patients (cases) was high, although not higher than that in controls with normal spirometry. In addition, cases had more hypoxemia during sleep than did controls. Our results suggest that sleep questionnaires do not have sufficient discriminatory power to identify OSA in cHP patients.
RESUMO Objetivo: Comparar pacientes com pneumonite de hipersensibilidade crônica (PHc) e controles com espirometria normal quanto às características do sono, bem como estabelecer a prevalência de apneia obstrutiva do sono (AOS) e hipoxemia noturna. Os objetivos secundários foram identificar fatores associados à AOS e hipoxemia noturna; correlacionar a hipoxemia noturna com o índice de apneias e hipopneias (IAH), função pulmonar, SpO2 em repouso, SpO2 em vigília e SpO2 durante o exercício; e avaliar o poder discriminatório de questionários do sono para predizer AOS. Métodos: Um total de 40 pacientes com PHc (casos) foram emparelhados por sexo, idade e IMC com 80 controles (2:1). O questionário STOP-Bang, a Escala de Sonolência de Epworth (ESE), o Índice de Qualidade do Sono de Pittsburgh, o questionário de Berlim e o escore Neck circumference, obesity, Snoring, Age, and Sex (NoSAS, circunferência do pescoço, obesidade, ronco, idade e sexo) foram aplicados a todos os casos, e ambos os grupos foram submetidos a polissonografia de noite inteira. Resultados: Os pacientes com PHc apresentaram maior latência do sono, menor eficiência do sono, menor IAH, menor índice de distúrbio respiratório, menos apneias centrais, menos apneias mistas e menos hipopneias do que os controles. Os pacientes com PHc apresentaram SpO2 noturna significativamente menor; a porcentagem do tempo total de sono com SpO2 < 90% foi maior que nos controles (mediana = 4,2; IIQ: 0,4-32,1 vs. mediana = 1,0; IIQ: 0,1-5,8; p = 0,01). Não houve diferenças significativas entre os casos com e sem AOS quanto à pontuação no questionário STOP-Bang, no NoSAS e na ESE. Conclusões: A prevalência de AOS em pacientes com PHc (casos) foi alta, embora não tenha sido maior que a observada em controles com espirometria normal. Além disso, os casos apresentaram mais hipoxemia durante o sono do que os controles. Nossos resultados sugerem que os questionários do sono não têm poder discriminatório suficiente para identificar AOS em pacientes com PHc.
RESUMO
ABSTRACT Many interstitial lung diseases (ILDs) share mechanisms that result in a progressive fibrosing phenotype. In Brazil, the most common progressive fibrosing interstitial lung diseases (PF-ILDs) are chronic hypersensitivity pneumonitis, idiopathic pulmonary fibrosis, unclassified ILD, and connective tissue diseases. PF-ILD is seen in approximately 30% of patients with ILD. Because PF-ILD is characterized by disease progression after initiation of appropriate treatment, a diagnosis of the disease resulting in fibrosis is critical. Different criteria have been proposed to define progressive disease, including worsening respiratory symptoms, lung function decline, and radiological evidence of disease progression. Although the time elapsed between diagnosis and progression varies, progression can occur at any time after diagnosis. Several factors indicate an increased risk of progression and death. In the last few years, antifibrotic drugs used in patients with idiopathic pulmonary fibrosis have been tested in patients with PF-ILD. The effects of nintedanib and placebo have been compared in patients with PF-ILD, a mean difference of 107.0 mL/year being observed, favoring nintedanib. The U.S. Food and Drug Administration and the Brazilian Health Regulatory Agency have approved the use of nintedanib in such patients on the basis of this finding. Pirfenidone has been evaluated in patients with unclassified ILD and in patients with other ILDs, the results being similar to those for nintedanib. More studies are needed in order to identify markers of increased risk of progression in patients with ILD and determine the likelihood of response to treatment with standard or new drugs.
RESUMO Muitas doenças pulmonares intersticiais (DPI) compartilham mecanismos que resultam em um fenótipo fibrosante progressivo. No Brasil, as doenças pulmonares intersticiais fibrosantes progressivas (DPI-FP) mais comuns são a pneumonite de hipersensibilidade crônica, a fibrose pulmonar idiopática, a DPI não classificada e as doenças do tecido conjuntivo. A DPI-FP é observada em aproximadamente 30% dos pacientes com DPI. Como a DPI-FP é caracterizada pela progressão da doença após o início do tratamento adequado, é fundamental diagnosticar a doença que resulta em fibrose. Diferentes critérios foram propostos para definir doença progressiva, incluindo piora dos sintomas respiratórios, declínio da função pulmonar e evidências radiológicas de progressão da doença. Embora o tempo decorrido entre o diagnóstico e a progressão varie, a progressão pode ocorrer a qualquer momento após o diagnóstico. Vários fatores indicam risco aumentado de progressão e morte. Nos últimos anos, antifibróticos usados em pacientes com fibrose pulmonar idiopática foram testados em pacientes com DPI-FP. Os efeitos do nintedanibe e placebo foram comparados em pacientes com DPI-FP, com diferença média de 107,0 mL/ano a favor do nintedanibe. A Food and Drug Administration (EUA) e a Agência Nacional de Vigilância Sanitária aprovaram o uso do nintedanibe em tais pacientes com base nesse achado. A pirfenidona foi avaliada em pacientes com DPI não classificada e em pacientes com outras DPI, e os resultados foram semelhantes aos do nintedanibe. Mais estudos são necessários para identificar marcadores de risco aumentado de progressão em pacientes com DPI e determinar a probabilidade de resposta ao tratamento com medicamentos-padrão ou novos.
RESUMO
ABSTRACT Objective: Biomarkers associated with mucin 1, such as Krebs von den Lungen-6 and carbohydrate antigen (CA) 15-3, are increased in various interstitial lung diseases. Our aim was to determine whether CA 15-3 could be considered a biomarker of disease severity in patients with chronic hypersensitivity pneumonitis (cHP). Methods: This was a prospective observational study involving adult patients with cHP. Serum levels of CA 15-3 were measured and were correlated with variables related to disease severity and extension. HRCT scans were quantitatively analyzed using a computational platform and an image analysis tool (Computer Aided Lung Informatics for Pathology Evaluation and Rating). CA 15-3 levels were normalized by logarithmic transformation. Results: The sample comprised 41 patients. The mean age of the patients was 60.1 ± 11.6 years. The mean FVC in % of predicted was 70.3% ± 17.3%, and the median of the serum level of CA 15-3 was 48.1 U/mL. CA 15-3 levels inversely correlated with FVC in % of predicted (r = −0,30; p = 0,05), DLCO in % of predicted (r = −0,54; p < 0,01), and SpO2 at the end of a 4-min step test (r = −0,59; p < 0,01), but they directly correlated with total quantitative HRCT scores (r = 0,47; p = 0,004), especially regarding ground-glass opacities (r = 0.58; p < 0,001). Conclusions: CA 15-3 is likely to be a biomarker of disease severity of patients with cHP, particularly regarding gas exchange abnormalities.
RESUMO Objetivo: Biomarcadores associados à mucina-1, tais como Krebs von den Lungen-6 e carbohydrate antigen (CA, antígeno carboidrato) 15-3, encontram-se aumentados em diversas doenças pulmonares intersticiais. Nosso objetivo foi determinar se CA 15-3 poderia ser considerado um biomarcador de gravidade de doença em pacientes com pneumonite de hipersensibilidade crônica (PHc). Métodos: Estudo prospectivo observacional envolvendo pacientes adultos com PHc. Os níveis séricos de CA 15-3 foram medidos e correlacionados com variáveis relacionadas à gravidade e extensão da doença. As imagens de TCAR foram analisadas quantitativamente utilizando uma plataforma computacional e uma ferramenta de análise de imagem (Computer-Aided Lung Informatics for Pathology Evaluation and Rating). Os níveis de CA 15-3 foram normalizados por transformação logarítmica. Resultados: A amostra foi composta por 41 pacientes. A média de idade dos pacientes foi de 60,1 ± 11,6 anos. A média da CVF em % do previsto foi de 70,3% ± 17,3%, e a mediana do nível sérico de CA 15-3 foi de 48,1 U/mL. Os níveis de CA 15-3 se correlacionaram inversamente com CVF em % do previsto (r = −0,30; p = 0,05), DLCO em % do previsto (r = −0,54; p < 0,01) e SpO2 ao final de um teste de degrau de 4 minutos (r = −0,59; p < 0,01), mas se correlacionaram diretamente com a pontuação quantitativa total da TCAR (r = 0,47; p = 0,004), especialmente quanto a opacidades em vidro fosco (r = 0,58; p < 0,001). Conclusões: É provável que o CA 15-3 seja um biomarcador de gravidade de doença em pacientes com PHc, particularmente quanto a anormalidades nas trocas gasosas.

OBJETIVO: El objetivo principal de este estudio fue determinar la incidencia de complicaciones post cirugía bucal. METODOLOGÍA: Se desarrolló un estudio observacional, descriptivo, con el uso del registro prospectivo de la totalidad de pacientes ingresados para cirugía bucal del Complejo Hospitalario San Borja-Arriarán durante doce meses de observación (abril 2017 a marzo 2018). RESULTADOS: La muestra estuvo conformada por 532 pacientes sometidos a procedimientos quirúrgicos de cirugía bucal y 29 casos de complicación postquirúrgica. La incidencia de complicaciones alcanzó un 5,5% y se observó de manera predominante en intervenciones de tipo exodoncia. La complicación mayormente observada fue la alveolitis alcanzando un 2,5% de las cirugías de terceros molares y un 3,7% de las exodoncias de otros dientes. Las hemorragias postoperatorias se observaron en un 1,1% de las cirugías de terceros molares. Otras complicaciones postquirúrgicas fueron abscesos de espacios faciales, parestesia del nervio alveolar inferior, hematomas, equimosis y periostitis. CONCLUSIÓN: Los resultados fueron similares a los reportados en la literatura tanto en su frecuencia como en el tipo de complicación.
OBJECTIVE: The main objective of this investigation was to determine the incidence of postoperative complications in oral surgery. MATERIALS AND METHODS: An observational and descriptive study was developed with the use of the prospective registry of the patients admitted for oral surgery in the San Borja Arriarán Hospital Complex for a twelve-month period of observation (April 2017 to March 2018). RESULTS: The sample consisted of 532 patients undergoing surgical procedures of oral surgery and 29 cases of postoperative complications. The incidence of complications reached 5,5% and it was observed predominantly in interventions of tooth extraction. The most commonly observed complication was dry socket, reaching 2,5% of third molar surgeries and 3,7% of extractions of other teeth. Postoperative hemorrhages were observed in 1,1% of third molar surgeries. Other postoperative complications were facial spaces abscesses, paresthesia of the inferior alveolar nerve, bruising, ecchymosis and periostitis. CONCLUSIONS: The results were similar to those reported in the literature both in their frequency and in the type of complication.

Para el diagnóstico certero de fibrosis pulmonar idiopática (FPI) es de vital importancia la presencia de un patrón tomográfico definitivo de neumonía intersticial usual (NIU), en un contexto clínico adecuado. El interrogatorio dirigido, el uso de cuestionarios validados, una evaluación reumatológica acuciosa y exámenes complementarios son importantes para descartar causas secundarias de fibrosis pulmonar como neumonitis por hipersensibilidad (NHS), enfermedades del tejido conectivo (ETC), toxicidad por drogas y algunas neumoconiosis que pueden imitar el patrón radiológico y muchas veces dificultar un diagnóstico adecuado de FPI.
For the accurate diagnosis of idiopathic pulmonary fibrosis (IPF), the presence of a definitive tomographic pattern of usual interstitial pneumonia (UIP) is of vital importance, in an appropriate clinical context. Targeted interrogation, the use of valid questionnaires, an acute rheumatologic evaluation and complementary examinations are important to rule out secondary causes such as hypersensitivity pneumonitis (HP), connective tissue diseases (CTD), drug toxicity and some pneumoconiosis that can mimic the radiological pattern and often hinder a clear diagnosis of IPF.

RESUMEN Introducción: la alveolitis dentaria es una complicación pos-textracción dental, local, dolorosa y reversible del alveolo. Objetivo: caracterizar la alveolitis dental en pacientes adultos del Policlínico "René Bedia Morales", perteneciente al municipio Boyeros. Mareriales y métodos: se realizó un estudio descriptivo de corte transversal, en el Policlínico "René Bedia Morales", municipio Boyeros, provincia La Habana, en el periodo comprendido de septiembre de 2016 a septiembre de 2017. El universo estuvo constituido por 250 pacientes, de ambos sexos. Diagnosticados con alveolitis dental tras haberse realizado exodoncia durante ese periodo. La muestra quedó conformada por 187 pacientes que cumplieron con los criterios de inclusión y exclusión. Se estudiaron las variables: edad, sexo, tipo de alveolitis y factores asociados a las mismas. La información fue recogida en un modelo de recogida de datos, bajo su consentimiento informado. Resultados: el grupo de edad más afectado fue el de 35-59 años, con 47,59 %. Predominó el sexo femenino, con un 66,84 %. Prevaleció la alveolitis seca, en un 55,08 %. Relacionado con las conductas inadecuadas del paciente, la afectación fue de un 40,64 %. El no cumplimiento de las indicaciones postoperatorias y fumar, luego de la exodoncia, fueron los factores más asociados a la alveolitis seca; con un 53,48 % y un 41,18 %, respectivamente. Conclusiones: la alveolitis afectó fundamentalmente a los pacientes de 35-59 años de edad, del sexo femenino. Con mayor frecuencia predominó la alveolitis seca relacionada a las conductas inadecuadas del paciente (AU).
ABSTRACT Introduction: Dental alveolitis is a local, painful dental pos extraction complication which is reversible. Objective: Provide a characterization of dental alveolitis in René Bedia Morales policlinic at Boyeros Municipality. Materials and methods: A descriptive transversal study was performed in René Bedia Morales policlinic at Boyeros Municipality, in Havana Province. The study was performed in a time span between September 2016 to September 2017. The study universe was constituted by 250 patients of both sexes diagnosed with dental alveolitis after have made extractions in that period of time and the sample remained formed for 187 patients , that met with the criteria of inclusion and exclusion. Age, sex, type of alveolitis and associated factors were the variables considered in the present study. The data was collected in a input data form, under the patients concern. Results: The most affected age group was from 35 to 59 years old which represents a 47,59 %, being the feminine sex the predominant group which represents a 66,84 %. Dry alveolitis was predominant in 55,08 % related to inadequate behaviors within a 40,64 % The most frequent factors associated to the non-fulfillment of the pos operatory orders, such as smoking after having performed the procedure of exodontia with a 53,48 % and 41,18 % respectively. Conclusions: Alveolitis mainly affects patients within 35-59 years old, feminine sex, and also related to inadequate behaviors of the patients (AU).

A pneumonia de hipersensibilidade (PH) constitui síndrome inflamatória causada pela resposta imune exagerada a partículas antigênicas inaladas. Objetivo: descrever características clínicas, radiológicas, funcionais esobrevida de pacientes com PH. Metodologia: estudo retrospectivo, envolvendo pacientes em acompanhamento no ambulatório de doenças pulmonares intersticiais do HC-UFMG no período de 2011 a 2015. Analisados dados clínicos, radiológicos, funcionais e morfológicos coletados através de um protocolo padronizado. Resultados: Dentre 139 pacientes com doenças intersticiais pulmonares, 34 (24%) tinham PH, com idade de 60,7 ± 18,1 anos. Exposição a mofo foi a etiologia mais frequente (19;55%). A forma crônica foi predominante (100% doas casos), assim como a presença de padrão reticular na tomografia de tórax (100%), com ou sem faveolamento. Observou-se distúrbio restritivo leve (CVF=69,00 ± 17,62L) associado a redução moderada da difusão de monóxido de carbono (59,20 ± 16,99%). O lavado broncoalveolar não auxiliou no diagnóstico e a biópsia transbrônquica foi diagnóstica em 5 (55%) casos e a biópsia cirúrgica foi conclusiva em 6 (85,7%). A sobrevida mediana foi de 75 meses. Conclusão: Nesta amostra de um ambulatório de referência, a PH respondeu por cerca de um quarto dos pacientes com doença intersticial pulmonar. A exposição a mofo foi a principal etiologia e a mortalidade significativa, o que reforça a importância da adoção de medidas preventivas através do reconhecimento precoce da exposição aos fatores de risco.

Hypersensitivity pneumonitis (HP) inflammatory is a syndrome caused by an excessive immune response to inhaled antigen particles. Objective:To describe clinical, radiological and functional characteristics and survival in patients with HP. Methodology: Retrospective study involving patients followed up at the pulmonary interstitial diseases clinic of the HC-UFMG from 2011 to 2015. Clinical, radiological, functional and morphological data were analysed from a standardized protocol. Results: Among 139 patients with interstitial lung disease, 34 (24%) had HP, aged 60.7 ± 18.1 years. Mold exposure was the most frequent cause (19; 55%). The chronic form predominated (100% donate cases), as well as the presence of reticular pattern on the chest tomography (100%), with or without honeycombing. There was mild restrictive lung disease (FVC = 69.00 ± 17,62L) associated with moderate reduction in carbon monoxide diffusion (59.20 ± 16.99%). Bronchoalveolar lavage did not help in the diagnosis and transbronchial biopsy was diagnostic in 5 (55%) cases; surgical biopsy was conclusive in 6 (85.7%). Median survival was 60 months. Conclusion: In this sample of a reference clinic, HP accounted for about a quarter of the patients with interstitial lung disease. The mold exposure was the main etiology and the mortality rate was significant, what reinforces the importance of adopting preventive measures through early recognition of exposure to risk factors.
