RESUMEN
PURPOSE: To investigate the safety and effectiveness of intranodal lymphangiography (INL) and lymphatic embolization (LE) in management of chylous ascites after oncologic surgery. MATERIALS AND METHODS: Retrospective review of records of patients who underwent INL with or without LE from January 2017 to June 2022 was performed. Adult patients with chylous ascites after oncologic surgery referred to interventional radiology after failure of conservative treatment were included. Thirty-nine patients who underwent 55 procedures were included (34 males and 5 females). Data on patient demographics, procedural technique, outcomes, and follow-up were collected. Descriptive statistics were used to illustrate technical success, clinical success, and adverse events. Univariate logistic regression analysis was performed to evaluate factors predicting clinical success. RESULTS: INL was technically successful in 54 of 55 procedures (98%; 95% confidence interval [CI], 90%-100%). A lymphatic leak was identified in 40 procedures, and LE was attempted in 36. LE was technically successful in 33 of the 36 procedures (92%; 95% CI, 78%-98%). Clinical success, defined as resolution of ascites with no need for peritoneovenous shunt placement or additional surgery, was achieved in 22 of 39 patients (56%; 95% CI, 40%-72%). Clinical success was achieved in 18 patients after 1 procedure, and patients who required repeat procedures were less likely to achieve clinical success (odds ratio, 0.16; 95% CI, 0.04-0.66; P = .012). Four grade 1 procedural adverse events were recorded. CONCLUSIONS: INL with or without LE is a safe minimally invasive tool that can help patients with chylous ascites after oncologic surgery who failed conservative treatment avoid more invasive interventions.

OBJETIVO: Determinar las características clínicas y epidemiológicas de los casos con tuberculosis (TB) activa en población de cárceles con VIH, que se ve especialmente afectada por ambas epidemias. La infección por VIH incrementa significativamente la probabilidad del desarrollo de TB. MATERIAL Y MÉTODOS: Se realizó un estudio de cohorte en sujetos infectados por VIH e internados en un reclusorio de la Ciudad de México. RESULTADOS: Se encontraron 172 pacientes con VIH, 28 con TB activa (16.3%) - 21 (12.2%) con afección pulmonar - con una tasa de incidencia de 7.7 por 100 sujetos/año para TB activa y de 4.7 por 100 sujetos/ año para TB pulmonar. No se encontró drogorresistencia. Dieciocho aislados fueron tipificados por RFLP, con una tasa de transmisión calculada de 11%. CONCLUSIÓN: Se encontró una prevalencia de TB en esta población mil veces superior a la observada en la población general y datos sugerentes de transmisión al interior de la cárcel.
OBJECTIVE: To determine the clinical and epidemiological characteristics of prison inmates with active tuberculosis in HIV-positive prison populations. MATERIALS AND METHODS: We conducted a cohort study in HIV-infected subjects in a prison in Mexico City, with the aim of determining clinical and epidemiological characteristics of cases with active TB. RESULTS: We detected 172 HIV infected inmates and TB in 28 of them (16.3%) - 21 (12.2) with pulmonary TB - with an incidence rate of 7.7/100 persons/year for active TB and 4.7/100 persons/year for pulmonary TB. No drug resistance was found. Two clusters (4 and 2 subjects) were observed after RFLP-typing of 18 isolates, with a transmission rate of 11% by molecular and clinical analysis. CONCLUSIONS: The prevalence of active TB was found to be a thousand times greater than in the general population. Evidence of transmission inside the prison was also found.
