Preoperative detection and evaluation of the need for psychological intervention in cancer and non-cancer patients referred to thoracic surgery / Detección y evaluación de la necesidad de atención psicológica preoperatoria en pacientes oncológicos y no oncológicos derivados a cirugía torácica

Objectives (a) to evaluate and compare the psychological treatment needs of patients with cancer and non-cancer, who are going to undergo scheduled thoracic surgery, and (b) evaluate and compare the diagnostic accuracy of the screening tests of psychological treatment needs for cancer and non-cancer patients. Method The need for psychological treatment was evaluated in a total of 169 patients prior to thoracic surgery, through a clinical interview. The screening tests used were: the physician's judgment (yes/no), the Hospital Anxiety and Depression Scale (HADS) and, the single-item interview to assess depression “Do you feel depressed?” (DEPQ). Results The number of patients who needed psychological treatment in the total sample was 47 (27.81%), in non-cancer-patients: 22 (30.99%) and in cancer patients: 25 (25.51%). The participants with treatment needs were more often young women with primary education levels, with more fears and concerns regarding their disease. With respect to the screening tests, the HADS-T (cut-off point ≥13) obtained a sensitivity (SE) of 0.75 and Specificity (SP) of 0.81 in the total sample. In patients with cancer, the HADS total score (cut-off point ≥10) obtained an SE=0.84 and SP=0.80, and, in non-cancer patients, the HADS total score (cut-off point ≥13) showed an SE=0.59 and SP=0.84. The DEPQ and the physician's judgment did not achieve adequate levels of precision. Conclusions A high percentage of patients have psychological treatment needs before performing thoracic surgery, which are similar for cancer and non-cancer patients. Preoperative detection of patients who need psychological intervention is feasible with a simple screening test: HADS, which achieves greater precision in cancer patients (AU)

Objetivos Evaluar y comparar: a) las necesidades de tratamiento psicológico de pacientes con cáncer y sin cáncer, que van a someterse a una cirugía torácica programada, y b) la precisión diagnóstica de las pruebas de detección de necesidades psicológicas para pacientes con y sin cáncer. Métodos Se evaluó la necesidad de tratamiento psicológico en un total de 169 pacientes antes de la cirugía torácica, a través de una entrevista clínica. Las pruebas de cribado fueron: el criterio médico (sí/no), la Escala de Ansiedad y Depresión Hospitalaria (HADS) y la entrevista de un solo ítem de depresión «¿Se siente deprimido?» (DEPQ). Resultados El número de pacientes que necesitaron tratamiento psicológico fue en el total 47 (27,81%), en pacientes sin cáncer: 22 (30,99%) y con cáncer: 25 (25,51%). Las participantes con necesidades de tratamiento eran con mayor frecuencia mujeres jóvenes con niveles de educación primaria y más temores con respecto a su enfermedad. Con respecto a las pruebas de detección, el HADS total (corte ≥ 13) obtuvo una sensibilidad (S)=0,75/especificidad (E)=0,81 en la muestra total. En pacientes con cáncer el HADS total (corte ≥ 10): S=0,84/E=0,80 y en pacientes sin cáncer, la HADS total (corte ≥ 13): S=0,59/E=0,84. DEPQ y juicio médico obtuvieron bajos niveles de precisión. Conclusiones Un alto porcentaje de pacientes antes de realizar una cirugía torácica tiene necesidades de tratamiento psicológico, similares para pacientes con y sin cáncer. La HADS total es un buen método de cribado de necesidades psicológicas, especialmente en pacientes con cáncer (AU)

Occult primary Sjögren Syndrome in patients with interstitial pneumonia with autoimmune features.

INTRODUCTION/OBJECTIVES: To define the performance of Minor Salivary Gland Biopsy (MSGB) and Dry Eye Tests (DET) to detect occult Sjögren Syndrome (SS) among Interstitial Pneumonia with Autoimmune Features (IPAF) patients. METHODS: Prospective study. Interstitial Lung Disease (ILD) patients without defined Connective Tissue Disease and one or more IPAF classification domains or xerophthalmia were included. MSGB, Schirmer's test (ST) and Ocular Staining Score (OSS) were performed in a blinded manner by experienced specialists. MSGB with ≥1 focus of lymphocytes and Dry Eye Test (DET) with OSS ≥ 5 and/or ST < 5 s were considered positive. SS was diagnosed according to the ACR 2016 criteria. RESULTS: 534 patients on the first consult were screened. 67 patients had at least one IPAF criteria, 53 (79.1%) female, mean age (SD) 64.2 years old (10.8). Positive ST in 36 (53.7%), positive OSS in 29 (43.3%) and positive MSGB in 36 (53.7%) were found. Finally, 27 (40.3%) met SS diagnostic criteria. 25 (37.3%) and 18 (26.8%) of them did not report dry eyes or dry mouth, respectively. 53 (79.1%) had negative anti SSA/Ro, 57 (85.1%) had negative anti LA/SSB, 30 (44.7%) had negative ANA, and 52 (77.6%) had negative RF, respectively. A significantly higher proportion of ANA (+), anti-SSA/Ro (+), anti-SSB/La (+), positive DET and positive MSGB were found in the SS population. CONCLUSIONS: A significant proportion of patients with occult SS were found in our study. MSGB and DET may be considered in the evaluation of IPAF patients.

[Alpha-1 antitrypsin deficiency and spontaneous pneumothorax. Just a coincidence?] / Deficiencia de alfa-1 antitripsina y neumotórax espontáneo ¿solo una coincidencia?

Alpha-1 antitrypsin (AAT) deficiency is one of the most common inherited disorders with a higher incidence in patients with chronic obstructive pulmonary disease (COPD). Its prevalence in patients with spontaneous pneumothorax is unknown. The objective was to estimate the prevalence of AAT deficiency in patients with spontaneous pneumothorax. This was a prospective cross-sectional study, in patients with spontaneous pneumothorax, where those with secondary pneumothorax were excluded. Quantification of serum AAT by nephelometry and subsequent rapid genotyping (real time PCR) was performed, in order to detect the most prevalent deficiency alleles (Z and S) in those subjects with serum AAT concentrations = 120 mg/dl. Fifty-eight patients with primary spontaneous pneumothorax were included. The average age was 34 ± 13 years with male predominance (72%) and high prevalence of current and past smoking (60%). Twenty six percent of them (95% CI: 15-39) presented AAT serum concentrations = 120mg/dl. We found 7 deficiency variants (12%; IC 95%: 5-23%). One patient presented a severe Pi•ZZ form (1.7%), 3 were heterozygotes Z (5.2%) and 3 heterozygotes S (5.2%). The prevalence of AAT deficient variants was high in patients with spontaneous pneumothorax.

La deficiencia de alfa-1 antitripsina (AAT) es uno de los trastornos hereditarios más frecuentes y con mayor incidencia en pacientes con enfermedad pulmonar obstructiva crónica (EPOC). Se desconoce su prevalencia en aquellos con neumotórax espontáneo. El objetivo fue estimar la prevalencia de deficiencia de AAT en sujetos con neumotórax espontáneo. El estudio fue prospectivo y de corte transversal en pacientes con neumotórax espontáneo primario. Se excluyeron aquellos con neumotórax secundario. Se realizó cuantificación de AAT en suero por nefelometría y posterior genotipificación rápida (PCR en tiempo real) para detectar los alelos de deficiencia más prevalentes (Z y S) en aquellos con concentraciones séricas = 120 mg/dl. Se incluyeron 58 pacientes con neumotórax espontáneo primario. La edad promedio fue de 34 ± 13 años con predominio de sexo masculino (72%) y alta prevalencia de tabaquismo actual y pasado (60%). Del total, el 26% (IC95%: 15-39) presentó concentraciones de AAT = 120mg/dl. Encontramos 7 formas deficitarias (12%; IC 95%: 5-23%). Un paciente presentó una forma grave Pi•ZZ (1.7%), 3 fueron heterocigotos Z (5.2%) y 3 heterocigotos S (5.2%). La prevalencia de variantes deficitarias de AAT fue alta en este grupo con neumotórax espontáneo.

Prevalencia de déficit de alfa-1 antitripsina en pacientes con EPOC en Argentina. Estudio DAAT.AR / Prevalence of Alpha-1 Antitrypsin Deficiency in COPD Patients in Argentina. The DAAT.AR Study

INTRODUCCIÓN: Existe subdiagnóstico del déficit grave de alfa-1 antitripsina (DAAT) a pesar de la recomendación de realizar la determinación de AAT en pacientes con enfermedad pulmonar obstructiva crónica (EPOC). OBJETIVO: Estimar la prevalencia de DAAT en pacientes con EPOC ajustada a la población del estudio de prevalencia de EPOC en la Argentina (EPOC.AR). MATERIAL Y MÉTODOS: Estudio prospectivo multicéntrico de corte transversal en población ≥ 30 años de edad con diagnóstico de EPOC. Cuantificación de AAT por toma de sangre capilar en gota seca y posterior genotipificación en aquellos sujetos con concentraciones < 1,5 mg/dl en sangre capilar en gota seca (< 80 mg/dl sérica). Se definió DAAT como la detección de las variantes ZZ o SZ por genotipificación. Se tomó la población del estudio EPOC.AR para calcular la prevalencia local ajustada. RESULTADOS: Se incluyeron 3.254 pacientes (544 con AAT < 80 mg/dl) con diagnóstico espirométrico de EPOC. La prevalencia de DAAT en la población total del estudio fue de 1,29% (IC 95% 0,93-1,74), de los cuales un 0,92% (IC 95% 0,62-1,31) fueron Pi*ZZ y un 0,37% (IC 95% 0,19-0,64) Pi*SZ. La prevalencia ajustada de DAAT en pacientes con EPOC (≥ 40 años) fue de 0,83% (IC 95% 0,23-2,08). Encontramos asociación negativa de DAAT con la edad (OR 0,94; IC 95% 0,90-0,98; p = 0,006), el consumo de tabaco (OR 0,98; IC 95% 0,96-0,99; p = 0,009) y el VEF1% (OR 0,95; IC 95% 0,91-0,99; p = 0,015). CONCLUSIONES: Se estima que la prevalencia de DAAT en la población adulta con EPOC en Argentina es del 0,83%, lo cual podría representar 17.000 casos en nuestro país

INTRODUCTION: Alpha-1 antitrypsin deficiency (AATD) is still underdiagnosed, despite the recommendation to determine AAT in patients with chronic obstructive pulmonary disease (COPD). OBJECTIVE: To estimate the prevalence of AATD in COPD patients adjusted according to the population of the COPD prevalence study in Argentina (EPOC.AR). MATERIAL AND METHODS: This was a multicenter prospective cross-sectional study of a population aged ≥ 30 years of age diagnosed with COPD, involving AAT quantification in dry blood spot and subsequent genotyping in subjects with < 1.5 mg/dL AAT in dry blood spot (< 80 mg/dL in serum). AAT was defined as the detection of variants ZZ or SZ on genotyping. The EPOC.AR study population was used to calculate local adjusted prevalence. RESULTS: We included 3,254 patients (544 with AAT < 80 mg/dL) with a spirometric diagnosis of COPD. The prevalence of AATD in the total study population was 1.29% (95% CI 0.93-1.74), of which 0.92% (95% CI 0.62-1.31) were Pi*ZZ and 0.37% (95% CI 0.19-0.64) Pi*SZ. The adjusted prevalence of AATD in COPD patients ≥ 40 years of age was 0.83% (95% CI 0.23-2.08). We found that AATD was negatively associated with age (OR 0.94; 95% CI 0.90-0.98; P = .006), smoking habit (OR 0.98; 95% CI 0.96-0.99; P = .009), and FEV1% (OR 0.95; 95% CI 0.91-0.99; P = .015). CONCLUSIONS: The prevalence of AATD in the adult population with COPD in Argentina is estimated to be 0.83%, which could represent 17,000 cases in our country

Linfangioma quístico intratorácico. Resección videotoracoscópica / Thoracic cystic lymphangioma. Thoracoscopic surgery

El linfangioma quístico mediastínico es un tumor benigno muy poco frecuente. Los pacientes que lo presentan no se diagnostican fácilmente porque están asintomáticos o con síntomas inespecíficos. Los quistes en general se encuentran incidentalmente y el diagnóstico preoperatorio es difícil por su apariencia atípica en los estudios de imagen. Habitualmente se diagnostican durante o después de la operación. Los quistes sintomáticos necesitan tratamiento y la escisión quirúrgica es el tratamiento de elección. Además, el abordaje quirúrgico estándar para la resección aún no ha sido bien establecido. Presentamos un caso de un paciente adulto con un linfangioma quístico mediastínico resecado con éxito por videotoracoscopia. La pieza quirúrgica reveló características de displasia linfática, y se diagnosticó como linfangioma mediastínico. Este caso muestra que la resección por videotoracoscopia es factible cuando se sospecha tumor quístico mediastínico, y que puede ser una alternativa a la toracotomía abierta para tratar el linfangioma quístico mediastínico

Mediastinal cystic lymphangioma is an extremely uncommon benign tumor. The patients with mediastinal cystic lymphangioma are often misdiagnosed because of no specific symptoms. The cysts usually are incidentally found and preoperative diagnosis is difficult due to their atypical appearance on imaging studies. Most cases are diagnosed during or after the operation. Symptomatic cysts need treatment, and surgical excision is the treatment of choice. Moreover, the standard surgical approach for resection has not yet been well established. We report a case of an adult patient with a mediastinal cystic lymphangioma that was successfully resected by video thoracoscopic surgery. The surgical specimen revealed features of lymphatic dysplasia, and was diagnosed it as mediastinal lymphangioma. This case report shows that resection by VTS is feasible when mediastinal cystic tumor is suspected, and that VATS may be an alternative to open thoracotomy to treat mediastinal cystic lymphangiom

[General characteristics of 29 patients with small vessel vasculitis]. / Características generales de 29 pacientes con vasculitis de pequeños vasos.

The objective of this series was to describe the general characteristics and clinical manifestations of patients with small vessel vasculitis who were assisted in the autoimmunity department of a community public hospital and to compare the results with the literature. Clinical records under the label of vasculitis in a period of 16 years were reviewed in a retrospective way. All patients selected fulfilled diagnostic criteria of small vessel vasculitis. The data were extracted and the analysis of survival was completed by phone. Later a bibliographical search was carried out and the results were compared. Thirteen patients with Wegener's granulomatosis, 6 with Churg-Strauss syndrome and 10 with microscopic polyangiitis were included. Fifty five percent (16) were under 55 years old when diagnosis was made and male/female ratio was 2.6 to 1. The diagnostic delay was over a year in 46% of the cases. Respiratory and ear-nose-throat were the most frequently affected systems. Anti-neutrophil cytoplasmic antibodies were present in 79% of patients. Overall mortality was 24% (7/29). There were several differences between the results of our series and the literature: the presentation form, affected systems and percentage of patients with anti-neutrophil cytoplasmic antibodies. Greater diagnostic delay and worse prognosis were observed in anti-neutrophil cytoplasmic antibody negative patients. Special attention should be given to these antibodies since they constitute a significant tool at the time of diagnosis.

Características generales de 29 pacientes con vasculitis de pequeños vasos / General characteristics of 29 patients with small vessel vasculitis

El objetivo de esta serie fue describir las características generales y manifestaciones clínicas de pacientes con vasculitis de pequeños vasos que concurrieron al servicio de autoinmunidad de un hospital de la comunidad y compararlas con la literatura. Se revisaron de manera retrospectiva las historias clínicas archivadas bajo el rótulo de vasculitis en un período de 16 años. Se seleccionaron aquellos pacientes que cumplieran criterios diagnósticos de vasculitis de pequeños vasos. Se extrajeron los datos de interés y se constató la supervivencia mediante contacto telefónico. Posteriormente se realizó una búsqueda bibliográfica y se compararon los resultados. Se incluyeron 13 pacientes con granulomatosis de Wegener, 6 con síndrome de Churg Strauss y 10 con poliangeítis microscópica. El 55% (16) fueron menores de 55 años al diagnóstico y hubo predominio del sexo femenino (2.6:1). La demora diagnóstica fue mayor a un año en el 46% de los casos. Los sistemas más frecuentemente afectados fueron respiratorio y otorrinolaringológico. El 79% presentó anticuerpos anti-citoplasma de neutrófilos (ANCA) positivos. La mortalidad fue del 24% (7/29). Al comparar las características de los pacientes incluidos en esta serie con lo descripto en la literatura, se hallaron diferencias en cuanto a la forma de presentación, sistemas comprometidos y porcentaje de pacientes ANCA positivos; además se observó que el resultado negativo de este marcador parece asociarse con mayor demora diagnóstica y en consecuencia peor pronóstico, lo que remarca su importancia como herramienta adicional no invasiva al momento del diagnóstico.
