RESUMO
BACKGROUND: Chagas disease is a systemic illness with widespread microvascular involvement. Experimental and clinical studies suggest that functional and structural microcirculatory abnormalities might be relevant to the disease progression. OBJECTIVES: To show the presence of sublingual microcirculatory alterations in patients with chronic Chagas disease. METHODS: This was a cross-sectional study including adult patients with serologic diagnosis of Chagas disease (n = 41) and control volunteers with negative serology (n = 38), from an endemic rural population. Study participants underwent clinical, electrocardiographic, echocardiographic, and sublingual videomicroscopic assessment. Videos were acquired by a sidestream-dark-field (SDF) imaging device and evaluated by a software-assisted analysis (AVA 3.2 software). FINDINGS: Most of Chagas disease patients were in the indeterminate phase (n = 34) and had lower heart rate and more echocardiographic abnormalities than control group (50 vs. 26%, p = 0.03). They also exhibited higher small microvessels total and perfused vascular density (20.12 ± 2.33 vs. 19.05 ± 2.25 and 20.03 ± 2.28 vs. 19.01 ± 2.25 mm/mm2, p < 0.05 for both). Other microvascular variables did not differ between groups. MAIN CONCLUSIONS: Patients with chronic Chagas disease exhibited increases in sublingual total and perfused microvascular density. Angiogenesis might be the underlying mechanism. The videomicroscopic assessment of mucosal sublingual microcirculation might be an additional tool in the monitoring of Chagas disease.

RESUMO
RESUMEN Introducción: Los desórdenes hipertensivos del embarazo (DHE) complican el 10% de los embarazos. Son la principal causa de mortalidad materna, y requieren un equipo multidisciplinario para su abordaje. Objetivos: Cuantificar prevalencia y definir características y evolución de los DHE en un centro con un programa dedicado para su abordaje. Material y métodos: Registro continuo y prospectivo desde noviembre 2019 hasta julio 2021 que incluyó todas las pacientes con DHE (Hipertensión arterial crónica - HTAC, hipertensión gestacional - HTg, preeclampsia precoz - PEp, preeclampsia tardía - PEt, preeclampsia sobreimpuesta - PESI, y eclampsia) y que cumplieran los criterios de inclusión. Se excluyeron las pacientes sin cobertura médica que impidiera su seguimiento ambulatorio a largo plazo en la institución. Se evaluaron características basales y evolución, tratamiento y persistencia de HTA luego del puerperio. Se analizó la incidencia de retardo en el crecimiento intrauterino (RCIU), parto pretérmino, mortalidad materna y muerte neonatal dentro de los primeros 28 días de vida. Resultados: Se realizaron 5825 partos/cesáreas y se incluyeron 152 pacientes que cumplieron criterios de inclusión, con HTg (37,5%), PEp (19,7%), PEt (38,8%), PESI (3,3%)), eclampsia (0,6%). Edad media 36,4 ± 5,6 años. El 38,1% recibió aspirina. Los antihipertensivos más utilizados fueron labetalol (65,8%) y enalapril (44,1 %) en el embarazo y el puerperio respectivamente. No hubo mortalidad materna, y la neonatal fue 3,6%. La persistencia de HTA fue del 20,0% Conclusión: La preeclampsia tardía fue el DHE más frecuente en la población analizada. Más de la mitad de las pacientes que desarrollaron DHE no recibían tratamiento preventivo con aspirina, evidenciándose un déficit en la identificación de la población de riesgo. Una de cada 5 pacientes con DHE quedó con hipertensión arterial crónica luego del puerperio.
ABSTRACT Background: Hypertensive disorders of pregnancy (HDP) complicate 10% of pregnancies. They are the main cause of maternal mortality and require a multidisciplinary team to address them. Objectives: The aim of this study was to quantify the prevalence and define the characteristics and outcome of HDP in a center with a program focused on its management. Methods: This was a continuous and prospective registry from November 2019 to July 2021 that included all patients with HDP [chronic hypertension (CHT), gestational hypertension (GHT), early-onset preeclampsia (EPE), late preeclampsia (LPE), superimposed preeclampsia (SIPE) and eclampsia] who met the inclusion criteria. Patients without medical coverage that prevented long-term outpatient follow-up at the institution were excluded. Baseline characteristics and evolution, treatment and persistent HT after puerperium were evaluated. The incidence of intrauterine growth retardation (IUGR), preterm delivery, maternal mortality and neonatal death within the first 28 days of life was analyzed. Results: Among a total f 5825 deliveries/caesarean sections, 152 patients with GHT (37.5%), EPE (19.7%), LPE (38.8%), SIPE (3.3%), and eclampsia (0.6%) who met the inclusion criteria were included in the study. Mean age was 36.4±5.6 years. Aspirin was administered to 38.1% of patients. The most commonly used antihypertensive drugs were labetalol (65.8%) and enalapril (44.1%) during pregnancy and puerperium, respectively. There was no maternal mortality, and neonatal mortality was 3.6%. Persistent HT was 20.0%. Conclusion: Late preeclampsia was the most frequent HDP in the population analyzed. More than half of the patients who developed HDP did not receive preventive treatment with aspirin, showing a deficit in the identification of the population at risk. One in 5 HDP patients remained with CHTN after puerperium.
RESUMO
We studied methods to convert medical prescriptions in free text to a structured form for pharmacy insructions and planning nursing activities in hospitalized patients. We compared Natural Language Processing (NLP) with Parsing Process (PP), both for the Spanish language. We studied 87,750 and processed 65,000 prescriptions and recovered 62% and 65% with NLP and PP to a structured format respectively. The difference between the methods is significant (p < 0.001) and further work is needed to determine if combining them will have higher performance.

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.

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.

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.
