RESUMO
Resumen Se considera vapeo a la inhalación de aerosoles generados por el calentamiento de líquidos. Existen dispositivos que se comercializan libremente para realizar vapeo, siendo los cigarrillos electrónicos los más frecuentes. Estos productos están asociados a la aparición de injuria pulmonar, ya sea injuria pulmonar inducida por vapeo (VAPI), o injuria pulmonar asociada a vapeo y cigarrillos electrónicos (EVALI). Se presenta el caso de una mujer de 54 años con antecedentes de vapeo en los últimos 9 meses. Consultó por disnea clase funcional IV asociada a náuseas y vómitos de 18 h de evolución. Al ingreso presentó insuficiencia respiratoria. Se realizó intubación orotraqueal con asistencia ventilatoria mecánica; la tomografía de tórax evidenció infiltrados alveolares difusos bilaterales. Se interpretó el cuadro clínico como VAPI/EVALI. Aún se desconoce la fisiopato genia exacta de la injuria pulmonar inducida por vapeo; la disnea y tos son los síntomas más frecuentes. Todos los pacientes tienen imágenes radiológicas patológicas. El soporte respiratorio y los corticoides sistémicos son el tratamiento de elección.
Abstract Vaping is considered to be the inhalation of aerosols generated by heating liquids. There are devices freely marketed for vaping, with electronic cigarettes being the most common. These products are associated with the appearance of lung injury, either vaping-induced lung injury (VAPI), or lung injury associated with vaping and electronic cigarettes (EVALI). We presented the case of a 54-year-old woman with a history of vaping in the last 9 months. She consulted for acute dyspnea (class IV) associated with nausea and vomiting of 18 hours of evolution. Upon admission, she presented respiratory failure. Orotracheal intubation was performed with mechanical ventilatory assistance. A chest tomography revealed bi lateral diffuse alveolar infiltrates. The clinical picture was interpreted as VAPI/EVALI. The exact pathophysiology of vaping-induced lung injury is still unknown; dyspnea and cough are the most frequent symptoms. All patients have pathological radiological images. Respiratory support and systemic corticosteroids are the treatment of choice.

El primer caso de infección por coronavirus (COVID-19) en Argentina se informó en Buenos Aires el 3 de marzo de 2020, en un paciente proveniente de Milán. El objetivo de este trabajo es describir las características clínicas y curso de la enfermedad de una serie de pacientes infectados con COVID-19 en un sanatorio privado durante el mes de marzo del 2020. Durante marzo 2020 se internaron 63 pacientes sospechosos de infección por COVID-19. Fueron diagnosticados 26 positivos para COVID-19 por hisopado nasofaríngeo, con el método RT-PCR para SARS Cov2. Se recopilaron datos sobre las características epidemiológicas, signos y síntomas, así como comorbilidades, laboratorio e imágenes. La edad promedio fue 40 años (SD ± 15 años); hubo un igual número de varones; solo 1 caso no venía del exter ior. El síntoma más frecuente fue la fiebre (24/26 casos) y la linfopenia (8/26). En un grupo (n = 17) la fiebre se limitó dentro de las primeras 72 h y en otro, la fiebre duró 6 o más días (7 casos). Hubo un fallecido entre los 26 casos. La población de nuestro estudio era joven y la mayoría de los casos fueron importados, en concordancia con el estadio de la epidemia en el momento en que el estudio fue realizado. Observamos que hubo 2 patrones en la curva térmica pero la persistencia de la fiebre no implicó un peor pronóstico. Se necesitan estudios poblacionales más grandes para confirmar estos hallazgos clínicos.
The first case of coronavirus (COVID-19) infection in Argentina was reported in Buenos Aires on March 3rd, 2020, in a patient who arrived from Milan. The aim of this study is to describe the clinical characteristics and course of illness of patients infected with Covid-19 that were hospitalized in a private clinical setting during March 2020. Sixty three patients suspected of COVID-19 infection, were admitted to our hospital during March 2020. Twenty six of these subjects were diagnosed positive by the RT-PCR for SARS Cov-2 in a nasopharyngeal swab specimen. We recorded data about epidemiological characteristics, clinical signs and symptoms, in addition to comorbidities, laboratory and radiological studies were done. The median age was 40 years (SD±15 years); there was an equal number of men and women; all the patients but one were coming from abroad; the most common symptom was fever (24/26 cases) and lymphopenia (n = 8). We found that there were patients in whom fever disappeared within the first 72h (n = 17) and another group in which the fever lasted six or more days (n = 7). One patient out of 26 died. The population of our study was young and almost all were imported cases, in alinement with the stage of the epidemic at the time when the study was conducted. We observed that there were two patterns in the fever curve but the persistence of it did not lead to a worse prognosis. Larger population studies are required in order to confirm these clinical findings.

La anestesia regional combinada es utilizada frecuentemente como herramienta para el tratamiento del dolor postoperatorio. Los efectos secundarios de los opioides utilizados por esta vía son similares a los que se presentan luego de la administración sistémica. La aparición de vértigo con nistagmo vertical es un efecto adverso muy pocas veces descripto con el uso de morfina por vía intratecal, epidural o endovenosa. Comunicamos el caso de un paciente que presentó esta complicación en el postoperatorio de una nefrectomía parcial, luego de la administración de morfina intratecal, con resolución completa mediante el uso de naloxona endovenosa.
Combined regional anesthesia is frequently used as a tool for management of postoperative pain. The profile of side effects of the opioids used via this route is similar to those occurring after systemic administration. The onset of vertigo with vertical nystagmus is an adverse effect rarely described after the use of intrathecal, epidural or intravenous morphine. We report the case of a patient who presented this complication in the postoperative period of a partial nephrectomy, after the administration of intrathecal morphine, with complete resolution by intravenous naloxone.

Wegener's granulomatosis (WG) forms part of a group of primary vasculitis of the small and medium-sized blood vessels, associated with antineutrophil cytoplasmic antibodies (ANCA). This disease may affect any body organ, especially the upper and lower airways and the kidneys. Hardly ever is otomastoiditis the first and only clinical manifestation of generalized Wegener's granulomatosis. We present the case of a patient whose disease started with the inflammation of the middle ear, which was unresponsive to the usual treatment. Later he developed nasal, pulmonary and renal compromise. The determination of ANCA and a transbronchial biopsy confirmed the diagnosis of WG. We report this case to express the view that otomastoiditis in adults, which is refractory to the usual treatment, may seldom be the first and only clinical manifestation of WG.

La granulomatosis de Wegener (GW) forma parte del grupo de vasculitis primarias, de vasos pequeños y medianos, asociadas a anticuerpos anticitoplasma de neutrófilos (ANCA). Esta enfermedad puede afectar cualquier órgano, especialmente vías aéreas superiores, inferiores y el riñón. Muy raramente la primera y única manifestación clínica de GW generalizada es la otomastoiditis. Presentamos el caso de un paciente que inició su enfermedad con una inflamación del oído medio, sin respuesta al tratamiento habitual. Posteriormente agregó compromiso nasal, pulmonar y renal. La determinación de anticuerpos anticitoplasma de neutrófilos y la biopsia transbronquial confirmaron el diagnóstico de GW. Comunicamos este caso para referir que la otomastoiditis del adulto, refractaria al tratamiento habitual, puede raramente ser la primera y única manifestación clínica de la GW.

El síndrome pulmón-riñón se define como una combinación de hemorragia alveolar difusa y glomerulonefritis. La coexistencia de estas dos afecciones clínicas se produce por enfermedades con distintos mecanismos patogénicos. Las vasculitis sistémicas primarias y el síndrome de Goodpasture son las etiologías más frecuentes. El lupus eritematoso sistémico, otras colagenopatías, las vasculitis con anticuerpos anticitoplasma de los neutrófilos negativos y las secundarias a drogas son causas mucho menos comunes. El diagnóstico temprano basado en criterios clínicos, radiológicos, de laboratorio e histológicos, permite iniciar el tratamiento disminuyendo su elevada morbi-mortalidad. La terapéutica se basa en altas dosis de corticoides, inmunosupresores, inhibidores del factor de necrosis tumoral y plasmaféresis.
The pulmonary-renal syndrome is defined as a combination of diffuse alveolar hemorrhage and glomerulonephritis. The coexistence of these two clinical conditions is due to diseases with different pathogenic mechanisms. Primary systemic vasculitis and Goodpasture syndrome are the most frequent etiologies. Systemic lupus erythematosus, connective tissue diseases, negative anti neutrophil cytoplasmic antibody vasculitis and those secondary to drugs are far less common causes. An early diagnosis based on clinical, radiologic, laboratory and histologic criteria enables early treatment, thus diminishing its high morbility-mortality rate. Therapy is based on high doses of corticosteroids, immunosuppressants, tumor necrosis factor inhibitors and plasmapheresis.

Post-operative fever incidence varies widely. In clean and clean-contaminated surgery the non-infectious fever is more frequent than the infectious fever. We performed a prospective study including 303 patients who underwent orthopedic and urologic elective surgery. The aims of our study were to investigate the incidence of post-operative fever, its etiology, the relationship between time of onset and the etiology, and the usefulness of extensive fever work-up to determine post-operative infection. The incidence of post-operative fever was 14% (42/303) of which 81% (34/42) was noninfectious and 19% (8/42) was infectious. The etiology of the fever in the first 48 hours after surgery was always non-infectious (p < 0.001). An extensive fever work-up was performed in patients who presented fever only after the initial 48 hours of surgery with normal physical examination (n = 19) consisting of chest x-ray, blood (2) and urine cultures. The chest x-ray was normal in all the patients, the urine cultures were positive in four cases (21%, IC 95%: 6-45) and the blood cultures in only one case (5%, IC 95%: 0.1-26). Seven patients had post-operative infections without fever as a clinical sign. The most frequently observed etiology of post-operative fever was non-infectious, related to the normal inflammatory host response to surgery. Based on the present results, the extensive fever work-up performed to investigate post-operative infection does not seem to be a useful tool. The diagnosis of post-operative infection was based on clinical follow up and the correct interpretation of the patient's symptoms and signs.

La incidencia de fiebre en el postoperatorio varía ampliamente. En la cirugía limpia y la limpia-contaminada, la fiebre no infecciosa es más frecuente que la infecciosa. Fueron estudiados prospectivamente 303 pacientes operados en forma programada de cirugía ortopédica y urológica. Se investigó la incidencia de fiebre postoperatoria, su etiología, la relación entre el momento de su aparición y su origen y la utilidad del pedido empírico de estudios para determinar infección postoperatoria. El 14% (42/303) de los pacientes tuvieron fiebre postoperatoria. En el 81% (34/42) su etiología fue no infecciosa y en el 19% (8/42) infecciosa. Su origen fue siempre no infeccioso dentro de las primeras 48 horas del postoperatorio (p<0.001). A 19 pacientes con fiebre después de las 48 horas y examen clínico normal, se les realizó radiografía de tórax, hemocultivos (2) y cultivo de orina. Las radiografías de tórax fueron normales en todos los casos, fueron positivos 4 urocultivos (21%, IC 95%: 6-45) y un hemocultivo (5%, IC 95%: 0.1-26). Siete pacientes tuvieron infecciones postoperatorias sin fiebre. La causa de fiebre postoperatoria más frecuente fue no infecciosa, causada por respuesta normal inflamatoria al trauma quirúrgico. La realización de estudios de rutina en pacientes con examen clínico normal y fiebre posterior a las 48 horas, de acuerdo a lo observado en este estudio, no permite sacar conclusiones definitivas. El diagnóstico de las infecciones postoperatorias se basó en el seguimiento clínico- quirúrgico y en la interpretación de los síntomas y signos del paciente.

Se hace una revisión de las Neumonías en Organización según el concepto actual de las mismas, su nomenclatura diferente de las usadas previamente (BOOP), y las características clínicas, clasificación etiológica, alteraciones funcionales y anormalidades en las imágenes. Se comentan 4 casos clínicos de interés, dos con confirmación biópsica, y dos debidos a toxicidad por amiodarona. Se describe la afectación clínica, funcional y radiológica de los casos y se enfatiza un paciente con alteración tomográfica inusual y otro con evolución fibrótica progresiva asociado a artritis reumatoidea que se hizo aparente un año después del COP y coincidió con una exacerbación tardía del mismo.
Organizing pneumonias are reviewed according to the new approach from ATS/ERS statement. Most frecuent clinical patterns, image studies and functional alterations are commented on. Four clinical cases are described, two with pathological confirmation and two other amiodarone related. Unusual HRTC presentation is remarked in one case and another one due to rheumatoid arthritis, with pulmonary alteration preceding in one year rheumatic manifestations and relapsing one year later simultaneously with clinical and serologic rheumatoid arthritis.
