Hemoptisis asociada a maniobra de valsalva secundaria a malformación arteriovenosa pulmonar rota en paciente con cirugía de Fontan. Revisión a propósito de un caso / Hemoptysis associated with valsalva maneuver secondary to ruptured pulmonary arteriovenous malformation in a patient with Fontan surgery. Review regarding a case

Se presenta un caso poco frecuente de hemoptisis en un paciente adolescente con cirugía de Fontan, causada por el sangrado de una malformación arteriovenosa pulmonar (MAVP), tras la práctica de un instrumento de viento (saxofón). El paciente se estudió con angiografía y se realizó cierre percutáneo, consiguiendo posteriormente mejoría clínica y evitando la aparición de nuevos episodios de hemoptisis. Actualmente existe escasa literatura que reporte casos de hemoptisis en pacientes con cirugía de Fontan y ningún caso publicado en relación a gatillantes relacionados a las maniobras de valsalva; como la generada al practicar instrumentos de viento. Por esta razón, se decide publicar este caso clínico en pro de generar mayores conocimientos en este grupo de pacientes con cardiopatías congénitas operadas con procedimientos paliativos como es la cirugía de Fontan.

A rare case of hemoptysis is presented in an adolescent patient with Fontan surgery, caused by bleeding from a pulmonary arteriovenous malformation (PAVM), after playing a wind instrument (saxophone). The patient was studied with angiography and percutaneous closure was performed, subsequently achieving clinical improvement and preventing the appearance of new episodes of hemoptysis. Currently, there is little literature on hemoptysis in patients with Fontan surgery and no case published in relation to triggers related to valsalva maneuvers; like that generated when practicing wind instruments. For this reason, it was decided to publish this clinical case in order to generate greater knowledge in this group of patients with congenital heart disease operated on with palliative procedures such as Fontan surgery.

Hemoptisis secundaria a tuberculosis pulmonar complicada con pseudoaneurisma de Rasmussen. Reporte de un caso en pediatría. / Hemoptysis in Pulmonary Tuberculosis Complicated by Rasmussen's Pseudoaneurysm. A Pediatric Case Report.

Presentamos el caso de un niño de 12 años que consultó por hemoptisis, sin otros sín- tomas asociados. Se realizó radiografía de tórax (patológica), laboratorio con aumen- to moderado de reactantes de fase aguda, PPD (negativa), esputos x 3 con bacilosco- pias negativas y tomografía de tórax con contraste i.v. que mostró imágenes de árbol en brote en todos los lóbulos y una imagen de dilatación vascular de una rama de la ar- teria pulmonar en lóbulo superior izquierdo. Se plantearon diagnósticos diferenciales: malformación vascular primaria o lesión secundaria a infección. La angiografía digital permitió confirmar el pseudoaneurisma y embolizarlo. Luego de 17 días, 2/3 cultivos de esputo fueron positivos para Mycobacterium tuberculosis. El niño realizó tratamiento antituberculoso con drogas de primera línea con evolución clínica favorable. Este caso resalta la importancia de considerar el pseudoaneurisma de Rasmussen en- tre las posibles complicaciones de un paciente con tuberculosis y hemoptisis recurren- te o masiva.

We present the case of a 12-year-old boy admitted to the hospital due to hemoptysis without other symptoms. We performed a Thorax X-Ray (pathological), laboratory with elevated acute phase reactants, TST (negative), sputum x 3 with negative smear and computed tomography angiography showing a tree-in-bud pattern in all lobes, and di-latation of a brunch of the pulmonary artery in the upper left lobe. We considered pri-mary vascular anomaly or lesion due to infection as a differential diagnosis. The patient underwent digital angiography and therapeutic embolization of this pseudoaneurysm. After seventeen days, 2/3 of the sputum cultures were positive for Mycobacterium tu-berculosis. The patient received standard anti-TB therapy with favorable evolution. This case highlights the importance of considering complications such as Rasmussen's pseudoaneurysm in patients with pulmonary tuberculosis and recurrent or massive hemoptysis.

Primary cardiac angiosarcoma presenting with haemoptysis.

A male patient in his 30s presented to the emergency room with a 1-week history of dyspnoea that progressed to haemoptysis, having coughed up approximately 200 mL of blood on two occasions. On diagnostic investigation, a mediastinal tumour infiltrating the free wall of the right atrium and multiple pulmonary nodules were discovered. The first suspicion was a neoplasm of pulmonary origin, and a bronchoscopy was performed, histology reported a probable cardiac origin for the neoplasm. A subsequent biopsy confirmed the presence of a primary cardiac angiosarcoma. An extension CT scan revealed brain metastases. The patient received chemotherapy treatment, resulting in a partial response to date. This case is one of the few reported instances of cardiac neoplasm presenting with respiratory symptoms.

Hemoptysis after COVID-19 and the importance of differential diagnosis: Birt-Hogg-Dubé syndrome.

Birt-Hogg-Dubé syndrome is a genodermatosis of autosomal dominant inheritance characterized by mutations in the folliculin (FLCN) gene. There is an inappropriate inhibition/activation of a protein, the foliculin, which may cause tumor lesions in skin, renal and lung lesions; they could have more risk of developing pneumothorax compared to the normal population. A 38-year-old male patient with bronchial asthma who consulted for hemoptysis three weeks after recovery from COVID-19 infection. A chest tomography was requested, showing an air cyst in the left lower lobe. Physical examination shows evidence of thoracic skin lesions which a skin biopsy was performed on. The results were compatible with fibrofolliculoma. Differential diagnoses were proposed. A genetic disorder associated with skin lesions was suspected. A multi-genetic panel that includes BRCA1, BRCA2, TP53 and FLCN genes was requested, which reported the mutation of the FLCN gene in heterozygosis classified as pathognomonic of Birt-Hogg-Dubé syndrome. Patient is currently under clinical follow-up while genetic counseling was requested for relatives.

El síndrome de Birt-Hogg-Dubé es una genodermatosis de herencia autosómica dominante caracterizada por mutaciones en el gen foliculina (FLCN), donde existe inhibición/activación inapropiada de una proteína, la foliculina, que puede causar lesiones tumorales sistémicas, principalmente a nivel de la piel, renal y lesiones pulmonares, presentando mayor riesgo de desarrollar neumotórax en comparación con la población normal. Comunicamos el caso de un varón de 38 años con asma bronquial que consultó por hemoptisis 3 semanas después de la recuperación de la infección por COVID-19. Se solicitó una tomografía de tórax, que mostró un quiste aéreo en el lóbulo inferior izquierdo. Además, presentaba en el examen físico una lesión cutánea que fue biopsiada, presentando diagnóstico de foliculoma. Se plantearon diagnósticos diferenciales y ante la sospecha de probable desorden genético, un panel genético fue solicitado. Se confirmó síndrome de Birt-Hogg-Dubé ante el hallazgo de la deleción heterocigota que comprende el exón 1 del gen FLCN clasificada como patogénica. Actualmente el paciente se encuentra en seguimiento clínico mientras se solicitó estudio genético para familiares.

Achados tomográficos incidentais de calcificações coronarianas: um estudo de prevalência na região sul do Brasil / Incidental tomographic findings of coronary artery calcifications: a prevalence study in southern Brazil

Fundamento: As calcificações de artérias coronárias (CAC) mostram-se como fator preditivo de doenças cardiovasculares (DCV). A tomografia computadorizada (TC) de tórax com protocolo de aquisição de baixa dose apresenta acurácia na identificação de CAC e propicia achados incidentais dessas calcificações, que são comumente negligenciados. Este estudo analisará a prevalência de achados incidentais de calcificação em artérias coronárias em indivíduos não cardiopatas submetidos à TC de tórax. Métodos: Estudo transversal consecutivo de caráter analítico e descritivo. Foram incluídos indivíduos de ambos os sexos que realizaram TC de tórax por encaminhamento, acima de 18 anos e não cardiopatas. A coleta de dados foi realizada por meio de prontuários e ficha de anamnese auto aplicada. As variáveis referentes às CAC e à extensão do comprometimento foram obtidas a partir da reavaliação das imagens de TC de tórax disponíveis no sistema da instituição. Os exames foram anonimizados e avaliados por dois médicos radiologistas experientes. Considerou-se como estatisticamente significativo p≤0,05. Resultados: Foram analisados 397 exames. Encontrou-se prevalência de calcificações em 176 (44%) dos casos. A existência dessas calcificações coronárias está relacionada à idade (p<0,001). As calcificações possuem relação com o sexo (p = 0,03) com maior razão de chance de desenvolvimento em homens (odds ratio [OR] = 1,55). O tabagismo (p<0,001), o sedentarismo (p<0,001), a hipertensão arterial sistêmica (p<0,001), o diabetes mellitus (p = 0,04) e as dislipidemias (p<0,001) mostraram associação positiva. Conclusão: A prevalência de achados incidentais de CAC foi de 44%; variam em maior número entre leve e grave; maior razão de chance no sexo masculino e aumento da prevalência com a idade. Portanto, a TC de tórax mostra-se um efetivo método para avaliar as CAC, e juntamente com a história clínica do paciente pode ser utilizada para medir os fatores de risco para doenças cardiovasculares e intervir no desfecho do quadro.(AU)

Introduction: Coronary artery calcifications (CAC) are shown to be a predictive factor of cardiovascular diseases. Computed tomography (CT) of the chest with a low-dose acquisition protocol is accurate in identifying CAC and provides incidental findings of these calcifications, which are commonly overlooked. This study will analyze the prevalence of incidental findings of calcification in coronary arteries in non-cardiac individuals undergoing chest CT. Methods: Consecutive cross-sectional study of an analytical and descriptive nature. Individuals of both genders who underwent chest CT by referral, over 18 years of age and without heart disease were included. Data collection was carried out using medical records and a self-applied anamnesis form. The variables referring to the CAC and the extension of the impairment were obtained from the reassessment of the chest CT images available in the institution's system. The exams were anonymized and evaluated by two experienced radiologists. P≤0.05 was considered statistically significant. Results: 397 exams were analyzed. A prevalence of calcifications was found in 176 (44%) of the cases. The existence of these coronary calcifications is related to age (p<0.001). Calcifications are related to gender (p = 0.03) with a higher odds ratio of development in men (odds ratio [OR] = 1.55). Smoking (p<0.001), sedentary lifestyle (p<0.001), systemic arterial hypertension (p<0.001), Diabetes Mellitus (p = 0.04), and dyslipidemia (p<0.001) showed a positive association. Conclusion: The prevalence of incidental CAC findings was 44%; vary in greater numbers between mild and severe; higher odds ratio in males and increased prevalence with age. Therefore, chest CT proves to be an effective method to assess CAC, and together with the patient's clinical history, it can be used to measure risk factors for CVD and intervene in the outcome of the condition.(AU)

Reporte de caso: hemoptisis masiva como manifestación clínica de un síndrome de Swyer-James-Mac Leod / Case report: massive hemoptysis as a clinical manifestation of Swyer-James-Mac Leod syndrome

El síndrome de Swyer-James-Mac Leod es una entidad poco frecuente adquirida en la infancia, generalmente tras una infección pulmonar moderada a grave de tipo bronquiolitis o neumonía, generalmente virales. Ocasionalmente se tiene el antecedente de infecciones repetidas de este tipo. Consiste en el desarrollo de enfisema hipoplásico pulmonar unilateral, que puede a veces relacionarse con bronquiectasias ipsilaterales o bilaterales, obstrucción fija al flujo aéreo y puede también asociarse a reducción del flujo sanguíneo del pulmón hipoplásico, de manera focal o difusa, con o sin tortuosidad de la vascularización proximal y a veces con una compensación del pulmón contralateral, en forma de sobredistensión e hiperflujo vascular relativo. Presentamos el caso de un varón de 79 años de edad con antecedentes de infecciones tipo bronquiolitis virales repetidas en la infancia, obstrucción fija grave al flujo aéreo y hemoptisis masiva secundaria a una infección por Pseudomonas aeruginosa sensible a la terapia antibiótica habitual.

Swyer-James-Mac Leod syndrome is a rare condition acquired in childhood, usually after a moderate to severe lung infection such as bronchiolitis or pneumonia, usually viral. Occasionally there is a history of repeated infections of this type. It consists of the development of unilateral pulmonary hypoplastic emphysema, which can sometimes be related to ipsilateral or bilateral bronchiectasis, fixed airflow obstruction, and may also be associated with reduced blood flow in the hypoplastic lung, with or without tortuosity of the proximal vascular supply and sometimes with compensation from the contralateral lung, in the form of overdistension and relative vascular hyperflow. We present the case of a 79-year-old man with a history of recurrent viral bronchiolitis-type infections in childhood, severe fixed airflow obstruction, and massive hemoptysis secondary to a Pseudomonas aeruginosa infection sensitive to usual antibiotic therapy.

Hemosiderosis pulmonar idiopática, caso clínico en México. Importancia de un diagnóstico y tratamiento oportuno / Idiopathic pulmonary hemosiderosis, clinical case in Mexico. The relevance of performed an early diagnosis and treatment

La hemosiderosis pulmonar idiopática (HPI) es una patología poco frecuente; su distribución geográfica, su incidencia y prevalencia se desconocen de manera exacta a nivel mundial. Tiene una fuerte asociación con condiciones autoinmunes y una adecuada respuesta al tratamiento inmunosupresor. A pesar de ser una patología grave, presenta una tasa de morbilidad y mortalidad mediana, siempre que se realice un diagnóstico y tratamiento precoz. Se presenta el caso clínico de una paciente femenina con diagnóstico de HPI quien cursó con la triada clásica de esta enfermedad: hemoptisis, anemia ferropénica e infiltrados pulmonares difusos. Se descartaron otras causas de hemorragia pulmonar difusa y se realizó el diagnóstico por biopsia pulmonar. Se trató con esteroides sistémicos e inhalados y azatioprina. Tras casi 2 años después del diagnóstico, estando sin tratamiento por 3 meses, presentó una exacerbación con hemorragia pulmonar masiva ocasionando el fallecimiento de la paciente.

Idiopathic pulmonary hemosiderosis (IPH) is a rare pathology; its geographic distribution, incidence and prevalence are not accurately known worldwide. It has a strong association with autoimmune conditions and has an adequate response to immunosuppressive treatment. Despite being a serious pathology, it has a medium morbidity and mortality rate, provided that early diagnosis and treatment is performed. We present the clinical case of a female patient diagnosed with IPH who presented with the classic triad of this disease: hemoptysis, iron deficiency anemia and diffuse pulmonary infiltrates. Other causes of diffuse pulmonary hemorrhage were ruled out and the diagnosis was made by lung biopsy. She was managed with systemic and inhaled steroids and azathioprine. After almost 2 years before the diagnosis, being without treatment for 3 month she had a massive pulmonary hemorrhage, causing the death of the patient.

Massive hemoptysis as a complication of pulmonary actinomycosis: a case report.

Massive hemoptysis is a rare life-threatening complication of pulmonary actinomycosis that should be treated promptly due to the risk of asphyxiation and hemodynamic instability. We present the case of a 57-year-old female who was presented to our center with massive hemoptysis. Thoracic computed tomography scan revealed a cavitated lesion with perilesional ground-glass opacity. Right lower lobectomy was then performed using uniportal video-assisted thoracic surgery, excising a 13 × 12 × 8 cm cavitated lung fragment. The pathology service reported the presence of microscopical evidence of filamentous gram positive bacterial colonies, showing compatible features of pulmonary actinomycosis. The patient was discharged with oral penicillin with an uneventful post-operative course.

La hemoptisis masiva es una complicación poco frecuente de la actinomicosis pulmonar que pone en peligro la vida del paciente y que debe ser tratada con prontitud debido al riesgo de asfixia e inestabilidad hemodinámica. Presentamos una mujer de 57 años que acudió a nuestro centro con hemoptisis masiva. La tomografía reveló una cavitación con opacidad perilesional en vidrio deslustrado. Realizamos lobectomía mediante cirugía uniportal, extirpando un fragmento de lesión. Patología informó de la presencia de colonias bacterianas filamentosas grampositivas, mostrando características compatibles con actinomicosis pulmonar. El paciente fue dado de alta con penicilina oral, con un curso postoperatorio sin incidentes.

Mycotic Pulmonary Aneurysm Managed With Covered Stent.

Mycotic aneurysms are vascular dilations caused by fungal or bacterial infections. The involvement of the pulmonary artery or its branches is extremely rare with only a few cases reported in the literature posing a diagnostic challenge. We present the case of a young adult patient with acute myeloid leukemia undergoing chemotherapy, who presented with febrile neutropenia, recurrent bacteremia due to Pseudomona Aeruginosa and Klebsiella Pneumonie and hemoptysis. The management was unconventional, opting for the placement of a covered endovascular stent, being the first successful case with this reported technique. Rapid detection of this pathology and individualization in the management of each patient is essential because of high risk of mortality due to sepsis and rupture of the aneurysm.

Hemorragia alveolar unilateral / Unilateral alveolar hemorrhage

Paciente masculino de 51 años de edad, ex tabaquista 34 paquetes/año, con diagnóstico de vasculitis ANCA C PR3+ en enero 2018: síndrome pulmón riñón (hemorragia alveolar difusa, sinusitis y compromiso renal), realizó tratamiento con ciclofosfamida, pulsos de corticoides y diálisis, quedando con enfermedad renal crónica estadio IV. En agosto 2019 consultó por cuadro clínico de 24 horas de evolución caracterizado por disnea progresiva hasta mMRC 2-3 asociado a hemoptisis en 3 oportunidades de 100ml cada uno aproximadamente, por lo que consulta. A su ingreso presentó episodio de hemoptisis de 200ml y desaturación con requerimiento de ventilación mecánica invasiva. En laboratorio de ingreso se objetivó caída de hematocrito de 12 puntos (Hto de 30 a 18,8%), empeoramiento de la enfermedad renal, cultivos negativos. Se realizó TACAR tórax: imagen cavitada de paredes finas sin contenido en su interior en lóbulo superior derecho. Múltiples imágenes en vidrio esmerilado con tendencia a la consolidación de distribución difusa que afecta casi la totalidad del hemitórax derecho a predominio del lóbulo inferior derecho (Figuras 1-3). Cultivo de aspirado traqueal: cerro flora habitual, hemocultivos negativos. Se interpretó como hemorragia alveolar difusa y se instauró tratamiento con Rituximab, corticoides y plasmaféresis

Clinical outcomes of cystic fibrosis patients with hemoptysis treated with bronchial artery embolization.

OBJECTIVE: Massive hemoptysis is one of the most serious complications in patients with cystic fibrosis (CF). This study aimed to evaluate the hemoptysis-free period following bronchial and non-bronchial artery embolization (BAE/non-BAE) in CF patients and to investigate predictors of recurrent bleeding and mortality by any cause. METHODS: This was a retrospective cohort study of CF patients ≥ 16 years of age undergoing BAE/non-BAE for hemoptysis between 2000 and 2017. RESULTS: We analyzed 39 hemoptysis episodes treated with BAE/non-BAE in 17 CF patients. Hemoptysis recurrence rate was 56.4%. Of the sample as a whole, 3 (17.6%) were hemoptysis-free during the study period, 2 (11.8%) underwent lung transplantation, and 3 (17.6%) died. The median hemoptysis-free period was 17 months. The median hemoptysis-free period was longer in patients with chronic infection with Pseudomonas aeruginosa (31 months; 95% CI: 0.00-68.5) than in those without that type of infection (4 months; 95% CI: 1.8-6.2; p = 0.017). However, this association was considered weak, and its clinical significance was uncertain due to the small number of patients without that infection. CONCLUSIONS: BAE appears to be effective in the treatment of hemoptysis in patients with CF.

Hemosiderosis pulmonar idiopática: seguimiento de pacientes durante 25 años (1995-2019) / Idiopathic pulmonary hemosiderosis: follow-up of patients for 25 years (1995-2019)

La hemosiderosis pulmonar idiopática (HPI) es una causa de hemorragia alveolar difusa. OBJETIVO: describir la evolución de niños con HPI en nuestra institución. Se realizó una revisión retrospectiva con protocolo de seguimiento. Se reclutaron 13 pacientes, 7 hombres. Procedentes de una zona agrícola (6/13). No todos presentaron la tríada diagnóstica completa: infiltrados algodonosos (9/13), anemia (11/13), hemoptisis (9/13). Todos evidenciaron un recuento de hemosiderófagos sobre 30% en el lavado broncoalveolar. Tomografía computada de tórax: normal (5/13), patrón intersticial (5/13), vidrio esmerilado (2/13) y fibrosis (1/13). Espirometría: normal (7/13), restrictiva (4/13), obstructiva (1/13) y no efectuada (1/13). Tratamiento durante la fase aguda: bolos de metilprednisolona (7/13) o prednisona (6/13) o hidrocortisona (1/13). En la fase de mantención se administró: prednisona (13/13) más un inmunosupresor, azathioprina (12/13), hidroxicloroquina (1/13), micofenolato (1/13), más budesonida MDI (13/13). Ocho pacientes detuvieron los sangrados. Dos pacientes fallecieron y hubo cinco embarazos de curso fisiológico en 3 adolescentes. Se observó: a) diferentes modalidades de presentación que retrasaron el diagnóstico; b) gran exposición a pesticidas; c) mejor pronóstico si el diagnóstico y el tratamiento eran precoces, también en niñas adolescentes; d) la mayoría detuvo los episodios de sangrado.

Idiopathic pulmonary hemosiderosis (IPH) is a cause of diffuse alveolar hemorrhage. OBJECTIVE: to describe the evolution of children with IPH in our institution. Retrospective monitoring with a follow-up protocol was carried out. 13 patients, seven males, were recruited. From an agricultural area (6/13). Not all of patients had the complete diagnostic triad: cotton infiltrates (9/13), anemia (11/13), hemoptysis (9/13). Hemosiderin-laden macrophages counting in the bronchoalveolar lavage fluid was over 30% in all the patients. Computed chest tomography was informed as normal (5/13), interstitial pattern (5/13), ground glass (2/13) and fibrosis (1/13). Spirometry: normal (7/13), restrictive (4/13), obstructive (1/13) and not performed (1/13). Treatment during the acute phase: bolus of methylprednisolone (7/13) or prednisone (6/13) or hydrocortisone (1/13). In the maintenance phase: prednisone (13/13) plus an immunosuppressant, azathioprine (12/13), hydroxychloroquine (1/13), mycophenolate (1/13), plus budesonide MDI (13/13). Eight patients stopped the bleeding episodes. Two patients died and there were five physiological pregnancies in 3 adolescents. It was observed:(a) different modes of IPH presentation that delayed its diagnosis; (b) large exposure to pesticides; (c) prognosis improved if diagnosis and treatment were early, also in adolescent girls; (d) most of the patients stopped the bleeding episodes.

Características demográficas, clínicas, radiológicas y de función pulmonar en pacientes con bronquiectasias / Radiological and pulmonary function clinical demographic characteristics in patients with bronchiectasias

OBJETIVOS: determinar las principales características demográficas, clínicas, radiológicas y de función pulmonar de los pacientes con bronquiectasias en la Clínica del Pulmón. MATERIAL Y MÉTODOS: estudio observacional, retrospectivo. Se revisaron las historias clínicas de 23 pacientes con diagnóstico de dilataciones bronquiales. RESULTADOS: de los 23 pacientes, con una edad media de 49,4 ± 3,87 años, 13 corresponden al sexo femenino y 10 al sexo masculino, el tiempo de evolución de la enfermedad desde el diagnóstico de la patología inicial es de 17,3 ± 2,92 años. La tuberculosis es la etiología principal en 15 pacientes (65,2%). Las manifestaciones clínicas más frecuentes son la tos y expectoración mucopurulenta por varios años en la mayoría de los pacientes, al que añadimos la disnea y hemoptisis, la auscultación pulmonar revela la presencia de crépitos en 17 pacientes (73,9%). La Tomografía de Tórax de Alta Resolución distingue dos tipos de bronquiectasias: La sacular o quística y la cilíndrica, de localización unilobar, bilobar y multilobar (difuso). La Espirometría Forzada fue indicada en 10 pacientes (43,5%) 7 mujeres y 3 varones, el Síndrome Bronquial Obstructivo fue el hallazgo más frecuente. La asociación de Tetraciclina con Metronidazol indicado en 9 pacientes (39,1%) mejoró el cuadro clínico. La fisiopatología de esta entidad clínica está sujeta a una constante actualización. CONCLUSIONES: en pacientes tosedores crónicos, las bronquiectasias deben tener prioridad diagnóstica, se trata de una patología antigua, pero de actualidad permanente.

The purpose of this document is to determine the main epidemiological and clinical characteristics of patients with bronchiectasis at the Lung Clinic. METHOD: observational, retrospective study. The medical records of 23 patients diagnosed with bronchial dilation were reviewed. RESULTS: the results of the 23 patients studied, with a mean age of 49,4 ± 3,87 years, 13 correspond to the female sex and 10 to the male sex, indicate that the time of evolution of the disease from the diagnosis of the initial pathology is: 17,3 ± 2,92 years. Tuberculosis is the main etiology in 15 patients (65,2%). The most frequent clinical manifestations were cough and mucopurulent expectoration of several years in most of the patients, to which we must add dyspnea and hemoptysis, pulmonary auscultation reveals the presence of crepitus in 17 patients (73,9%). High Resolution Chest Tomography distinguishes two types of bronchiectasis: the saccular or cystic and the cylindrical, the localization is unilobar, bilobar and multilobar (diffuse). Forced spirometry was indicated in 10 patients (43,5%), 7 women and 3 men, Chronic Obstructive Pulmonary Disease is the main diagnosis. The association of Tetracycline with Metronidazole indicated in 9 patients (39,1%) had positive results. The pathophysiology of this clinical entity is subject to constant updating. CONCLUSIONS: in chronic coughing patients, bronchiectasis must have diagnostic priority, it is an old pathology, but it is permanently current

Hemoptysis as a warning sign of thoracic aorta pseudoaneurysm: A case report. / Hemoptisis como signo de alarma de pseudoaneurisma de la aorta torácica: reporte de caso.

Pseudoaneurysm is defined as a reperfused pulsatile hematoma, encapsulated and communicated with the damaged vessel's lumen. It originates when there is a disruption of the arterial wall. Hemoptysis is a very rare sign/symptom of a thoracic aortic aneurysm or pseudoaneurysm. There is little information on hemoptysis associated with aortic aneurysm rupture, whose mechanisms are not explained by the presence of an aortopulmonary fistula. Among the hypotheses to explain this phenomenon, is the ability of the bronchial arteries to become hyperplasic and tortuous in the presence of a lesion that modifies the pulmonary architecture, being more susceptible to rupture. There are also descriptions of direct lung parenchymal injury from ruptured aneurysm. The present case illustrates that we must consider the hemoptysis as a warning sign in differential diagnosis of aortic aneurysms and pseudo aneurysms, among other causes, that it can be fatal in a short time due to massive hemorrhage.

El pseudoaneurisma se define como un hematoma pulsátil repermeabilizado, encapsulado y en comunicación con la luz de un vaso dañado. Se origina cuando hay una disrupción de la pared arterial. La hemoptisis es un signo/síntoma de presentación muy rara de aneurisma aórtico torácico y de pseudoaneurisma aórtico torácico. Hay poca información sobre la hemoptisis asociada con la ruptura del aneurisma aórtico cuyo mecanismo no se explica por la presencia de una fístula aortopulmonar. Entre las hipótesis para explicar este fenómeno, se encuentra la capacidad de las arterias bronquiales de volverse hiperplásicas y tortuosas en presencia de una lesión que modifica la arquitectura pulmonar, siendo más susceptibles a la ruptura. También hay descripciones de lesiones directas del parénquima pulmonar por aneurisma roto. El presente caso nos ilustra que debemos considerar a la hemoptisis como signo de alarma en el diagnóstico diferencial de los aneurismas y pseudoaneurismas aórticos entre otras causas que puede ser fatal en breve tiempo por una hemorragia masiva.

Case for diagnosis. Cutaneous small vessel vasculitis (anti-proteinase 3 positive), fever, hemoptysis, and lung cavitation in an adult

Abstract Small vessel vasculitis with anti-proteinase antibodies 3 is an atypical clinical presentation of tuberculosis. The authors present the case of a 47-year-old male patient, with palpable purpura and palmoplantar hemorrhagic blisters, with subsequent dissemination. He presented severe pulmonary symptoms with cavitation, fever, hemoptysis, and high levels of anti-proteinase 3. Histopathological assessment of the skin revealed small vessel vasculitis; pulmonary histopathology showed granulomas with caseation. Bronchoalveolar lavage was positive for alcohol-acid-fast bacilli. In countries with a high prevalence of tuberculosis, the presence of autoantibodies in a patient with vasculitis, fever, and pulmonary cavitation requires investigation of infectious causes.
