Peritoneal lymphomatosis. A case report

ABSTRACT Introduction: Involvement of the peritoneum occurs very rarely and is exceptional as an exclusive extranodal presentation of lymphomas. In most cases lymphomas associated with this rare entity are high-grade ones. PL secondary to high-grade nodal lymphoma is more frequent than primary peritoneal lymphoma, and there are only a few cases of the latter described in the literature. Description of the case: We present the case of a patient with constitutional syndrome and imaging findings suggestive of peritoneal carcinomatosis who was finally diagnosed with a Diffuse Large B-cell Lymphoma (DLBCL) by an ultrasound-guided core needle biopsy (CNB) of peritoneum. The patient received one polychemotherapy cycle; however tumor lysis syndrome occurred with death of the patient in the following days. This case tries to show the existence of a PL without other radiological findings of lymphoma, a fact that is very exceptionally described in the literature. Discussion: The differential diagnosis between PL and others peritoneum diseases such as peritoneal carcinomatosis, malignant primary peritoneal mesotheliomas, tuberculous peritonitis, sarcomatosis, diffuse peritoneal leiomyomatosis or benign splenosis, constitutes a major problem in imaging techniques. An exhaustive analysis of the radiological characteristics as well as a clinical-analytical context allows the differential diagnosis against peritoneal carcinomatosis and the rest of the entities previously referred although the final diagnosis will always be a biopsy. Conclusion: PL usually manifests as an aggressive histological subtype of high-grade lymphomas leading to a rapid progression and deterioration of the patient. It is crucial for the radiologist and the clinician to be aware of this rare entity providing the earliest possible diagnosis and optimal treatment to prolong the patient's life.

Clinical, laboratory, microbiological and echocardiographic characteristics of infective endocarditis in a tertiary care hospital

Abstract Objectives: infective endocarditis (IE) is a potentially fatal disease. This study analyzed the clinical, laboratory, microbiological and echocardiographic characteristics of IE in a population of patients at a tertiary care hospital in Medellín, Colombia, over a three-year period. Methods: a retrospective observational study. The patients were classified according to the modified Duke criteria. Clinical and echocardiographic data, laboratory results and cultures were gathered from the clinical charts. Factors associated with the prognosis were determined. Results: a total of 48 cases were included, 29 (60.4%) of which involved males. The mean age was 53.8±19.2 years. Fever and fatigue were the most common clinical signs. No heart murmur was reported on admission in 52.1% of the patients. Most of the patients (62.5%) had no underlying predisposing heart condition. The IE occurred in a native valve in 36 patients (75%), with the mitral valve being the most frequently affected site. Transthoracic and/or transesophageal echocardiography showed vegetations in 45 cases (93.7%); these were mostly mobile, with an average size of 17.6±11.3 mm. Staphylococcus aureus was the main causal organism (33%). The prevalence of IE with negative blood cultures was 37.5%. The most frequent complication was embolism in 21 patients (43.7%), followed by heart failure (41.7%). On multivariate analysis, septic shock, kidney failure, Staphylococcus infection and the use of immunosuppressants were predictors of higher inpatient mortality. Conclusions: most cases occur in elderly patients with no underlying predisposing heart condi tion, in a native valve, with a predilection for the mitral valve. Staphylococcus aureus is the most frequent causal organism. Several factors predict greater inpatient mortality, including the presence of septic shock, kidney failure, Staphylococcus infection and the use of immunosuppressants. (Acta Med Colomb 2021; 46.

Social and Clinical Impact of Congenital Urological Malformations in a Developing Country: The Need for a Transdisciplinary Way of Treatment / Impacto social y clínico de las malformaciones urológicas congénitas en un país en desarrollo: La necesidad de un tratamiento transdisciplinario

Zoom Image Abstract Introduction The prognosis of congenital anomalies (CAs) can be improved if detected and treated accurately. Given the complexity of some anomalies, it is almost always necessary to approach them with an interdisciplinary team. Our objective was to contact patients with congenital urological anomalies (CUAs) and follow them up during their first years of life and evaluate their clinical status, as well as their social and health care limitations. Method Based on the Bogota Congenital Malformations Surveillance Program (BCMSP), we have contacted by phone all the patients with CUAs and evaluated their follow-up. We have included all the registered patients from 2006 until 2015. A standardized questionnaire was applied by a trained staff. The questions assessed on each call included: evaluation of the clinical status of the patient, the clinical treatments and evaluations performed by clinical and surgical subspecialties, health care limitations, and social barriers. The first call was made at the 2nd month, then every 3 months during the 1st year and every 6 months thereafter. Results A total of 277 patients were contacted, 97.3% of whom have an increased risk of mortality or significant disability. The malformation related mortality was of 38.1%. Only 38.7% of the patients were evaluated by a specialist, while 57.4% where still waiting to be seen by a specialist. Ninety eight percent of the limitations related to the health care system were the long waiting lists to be seen by a specialist. Conclusion Many of the pathologies that we have found belong to the group that has a significant reduction in mortality when treated accurately and promptly. However, we have a profound problem in our health care system, in that many of the patients have not been seen by a specialist, which results in a worse prognosis and recovery rate.

Introducción El pronóstico de las anomalías congénitas puede mejorarse si se detectan y tratan adecuadamente. Dada la complejidad de algunas anomalías, casi siempre es necesario abordarlas con un equipo interdisciplinario. Nuestro objetivo fue contactar a los pacientes con anomalías urológicas congénitas (CUA) con posterior seguimiento durante los primeros años de vida, se evaluó su estado clínico así como las limitaciones sociales y de atención médica. Método Basado en el Programa de Vigilancia de Malformaciones congénitas de Bogotá, contactamos por teléfono a todos los pacientes con CUA y evaluamos su seguimiento. Fueron incluidos todos los pacientes desde 2006 hasta 2015. Un cuestionario estandarizado fue aplicado por personal capacitado. Las preguntas evaluadas durante la llamada incluyeron: evaluación del estado clínico, tratamientos clínicos realizados y evaluaciones por subespecialidades clínicas y quirúrgicas, limitaciones de atención médica y barreras sociales. La primera llamada se realizó en el segundo mes y luego cada tres meses durante el primer año y luego cada 6 meses a partir de entonces. Resultados Se contactó a un total de 277 pacientes en los que el 97,3% tenía un riesgo de mortalidad o de discapacidad significativa. La mortalidad relacionada con la malformación fue del 38.1%. Solo el 38,7% de los pacientes fueron evaluados por un especialista, mientras que el 57,4% aún esperaban ser atendidos por un especialista. El noventa y ocho por ciento de las limitaciones relacionadas con el sistema de atención fueron las largas listas de espera para ser visto por un especialista. Conclusión Muchas de las patologías pertenecen al grupo que cuando son tratadas adecuadamente y prontamente tienen una reducción significativa en la mortalidad. Sin embargo, tenemos un problema profundo en nuestro sistema de atención médica donde muchos de los pacientes no han sido atendidos por un especialista, lo que resulta en un peor pronóstico y tasa de recuperación.

Dolor en personas ancianas con dependencia: programa de visita domiciliaria adaptado culturalmente a población rural / Pain in dependent elderly people: home visit program culturally adapted to a rural population

RESUMEN Objetivo Evaluar los efectos de un programa de visita domiciliaria culturalmente adaptado sobre la intensidad del dolor de personas ancianas en situación de discapacidad y pobreza en la población rural de Cáqueza-Cundinamarca. Método Estudio cuasi-experimental con pre-prueba y post-prueba. Participaron 34 mayores de 60 años con deficiencia física o visual y dependencia total o parcial. El programa de visita domiciliaria constó de siete visitas con un promedio de dos horas de duración y un intervalo de 13 a 15 días. Para el manejo del dolor se propuso un sincretismo entre medicamentos, plantas medicinales y remedios caseros. El dolor se evaluó con la escala verbal del dolor y en diario de campo fueron registrados los datos cualitativos. Se aplicó la prueba de rangos asignados de Wilcoxon. Resultados En la pre-prueba el 100 % tenían un tipo de dolor y en la post-prueba hubo efectos favorables y significativos (p.valor <0.001) en la disminución del dolor. Cualitativamente son atribuidos los cambios en parte al desarrollo del programa y otras explicaciones corresponden a los valores y creencias del grupo. Conclusiones El programa de visita domiciliaria adaptado culturalmente deja evidencia cómo ofrecer una respuesta donde se dialoga entre el saber popular y profesional logrando una práctica segura y adaptada al universo cultural de las personas. Latinoamerica requiere de profesionales culturalmente sensibles a las expresiones y percepciones de dolor con curiosidad para explorar en la evidencia las posibilidades terapéuticas de las propuestas provenientes del saber popular.(AU)

ABSTRACT Objective To assess the effects of a culturally adapted home visit program on pain intensity in elderly people with disability and poverty conditions in the rural population of Cáqueza-Cundinamarca, Colombia. Method Quasi-experimental study with pre-test and post-test. The study included 34 people over 60 years of age with physical or visual impairment and total or partial dependence. The home visit program consisted of seven visits paid for an average of two hours and an interval of 13 to 15 days. A syncretism of drugs, medicinal plants and home remedies was proposed for pain management. Pain was assessed using the verbal pain scale and qualitative data were recorded in the field diary. Wilcoxon signed-rank test was applied. Results During the pre-test, 100 % of the participants presented with a type of pain, while favorable and significant effects were observed in the post-test (p value <0.001) in relation to pain reduction. Changes are qualitatively attributed, partly, to the development of the program and other explanations include values and beliefs of the group. Conclusions The culturally adapted home visits program shows that it is possible to act in contexts where dialogues occur between popular and professional knowledge, achieving a safe practice adapted to the cultural universe of people. Latin America requires professionals culturally sensitive to expressions and perceptions of pain, who are curious to explore, based on evidence, the therapeutic possibilities proposed by popular knowledge.(AU)

Experiencia clínica con infecciones causadas por Klebsiella pneumoniae productora de carbapenemasa, en una institución de enseñanza universitaria en Medellín, Colombia / Clinical experience with infections caused by carbapenemase-producing Klebsiella pneumoniae in a tertiary care teaching institution in Medellin, Colombia

Antecedentes: Las infecciones por Klebsiella pneumoniae productora de carbapenemasa (KPC) son un problema de salud pública mundial. Desde 2008 nuestra institución experimenta casos endémicos de infecciones por KPC posteriores a un brote cuyo caso índice fue un paciente de Israel admitido para trasplante hepático. Objetivo: Describir características clínicas y mortalidad en pacientes hospitalizados con infecciones nosocomiales por KPC. Métodos: Estudio observacional retrospectivo, descriptivo. Resultados: Un total de 52 pacientes fueron incluidos, la edad media fue 45,7 ± 27 años, 65,4% fueron hombres. Uso de inmunosupresores, cirugía gastrointestinal, hepatopatía crónica y trasplante de órgano sólido fueron las comorbilidades importantes. El 100% recibió antibióticos antes de la infección por KPC. Las principales infecciones fueron bacteriemia (30,7%), infección intraabdominal (23,1%) y neumonía (17,3%). El tratamiento fue dirigido por antibiograma en 50,7%. Tigeciclina fue administrada en el 51,9% y colistina en el 32,7%, ambas en terapia combinada con otros antibióticos. En el 15,4% se utilizó tigeciclina más colistina. La duración del tratamiento fue 15,7 ± 7,5 días. El 51,9% desarrolló bacteriemia y falla renal aguda y el 76,9% requirió atención en UCI. La mortalidad fue 48,1% y fue significativamente mayor en pacientes con bacteriemia vs. sin bacteriemia (74,1 vs. 20%; p = 0,01). No hubo diferencias significativas en mortalidad cuando se comparó uso de tigeciclina vs. colistina (45 vs. 52%; p = 0,609). Conclusión: La inmunosupresión, cirugía gastrointestinal, tratamiento previo con antibióticos y estancia en UCI son factores importantes para la infección por KPC. La mortalidad es alta a pesar de la terapia dirigida, especialmente en pacientes con bacteriemia.

Background: Carbapenemase-producing Klebsiella pneumoniae (KPC) infections are a worldwide public health problem. Since 2008, our institution has experienced endemic cases of KPC infection after an outbreak whose index case was a patient from Israel admitted for liver transplantation. Objective: To describe the clinical characteristics and mortality of inpatients with nosocomial KPC infections. Methods: Retrospective, descriptive observational study. Results: A total of 52 patients were included, with an average age of 45.7 ± 27 years; 65.4% were men. Use of immunosuppressants, gastrointestinal surgery, chronic liver disease and solid organ transplantation were significant comorbidities. All the patients had received antibiotics before the KPC infection. The primary infections were bacteraemia (30.7%), intra-abdominal infections (23.1%) and pneumonia (17.3%). Treatment was directed by antibiogram in 50.7% of cases. Tigecycline was administered in 51.9% of cases and colistin in 32.7%, both in combination therapy with other antibiotics. Colistin plus tigecycline was used in 15.4% of cases. The treatment duration was 15.7 ± 7.5 days, with 51.9% of patients developing bacteraemia and acute renal failure and 76.9% requiring ICU care. Mortality was 48.1% and was significantly higher in the patients with bacteraemia compared with those without (74.1 vs. 20%, respectively, p = 0.01). There were no significant differences in mortality between tigecycline and colistin use (45 vs. 52%, respectively, p = 0.609). Conclusion: Immunosuppression, gastrointestinal surgery, previous treatment with antibiotics and ICU stay are important factors for infection with KPC. Mortality is high despite targeted therapy, particularly in patients with bacteraemia.

Características clínicas, factores de riesgo y perfil de susceptibilidad de las infecciones por micobacterias documentadas por cultivo, en un hospital universitario de alta complejidad en Medellín (Colombia) / Clinical features, risk factors and susceptibility profile of mycobacterial infections documented by culture in a university hospital of high complexity in Medellin (Colombia)

Introduction: Tuberculosis (TB) remains an entity of high prevalence and mortality worldwide. The rising drug resistance is a public health problem. Besides, non-tuberculosis mycobacterial (NTM) infections are described with increasing frequency in areas of high prevalence of TB. Objectives: To determine epidemiological, clinical and microbiological characteristics of mycobacterial infections documented by culture. Materials and Methods: An observational, descriptive study in hospitalized patients. Results: M. tuberculosis complex was identified in 90,9% of 187 patients; 9,1% had NTM, 64% were male and the mean age was 40 years (range 1-88 years). The main co-morbidities were HIV / AIDS (23.5%), use of corticosteroids (13.3%) and chronic kidney disease (9.6%). Clinical forms were pulmonary (56.6%), extra-pulmonary (23.9%) and disseminated (19.2 The most common extra-pulmonary compromise was nodal (7.4%) and gastrointestinal (7%). 10.6% of M. tuberculosis were multi-drugresistant (MDR) and 2.12% had extended drug resistance (XDR). Mycobacterium avium andM. abscessus were the most frequent NTM. Overall mortality was 10%. Conclusions: In our study immune suppression is the main risk factor for extrapulmonary and disseminated disease. Resistance, MDR and XDR is higher in inpatients with TB. MNT infections are not uncommon in our country.

Introducción: Tuberculosis (TBC) es aún una entidad de alta prevalencia y mortalidad en el mundo. La resistencia ascendente a fármacos es un problema de salud pública. Además se describen con mayor frecuencia infecciones por micobacterias no tuberculosas (MNT) en áreas de alta prevalencia de TBC. Objetivos: Determinar características epidemiológicas, clínicas y microbiológicas de las infecciones por micobacterias documentadas por cultivo. Materiales y Métodos: Estudio observacional, descriptivo, en pacientes hospitalizados. Resultados: De 187 pacientes, en 90,9% se identificó complejo M. tuberculosis y en 9,1% MNT; 64% fueron hombres. Edad promedio 40 años (rango 1-88 años). Las principales co-morbilidades fueron infección por VIH/SIDA (23,5%), uso de corticoesteroides (13,3%) y enfermedad renal crónica (9,6%). Las formas clínicas fueron pulmonares (56,6%), extra-pulmonares (23,9%) y diseminadas (19,2%). El compromiso extra-pulmonar más frecuente fue ganglionar (7,4%) y gastrointestinal (7%). En M. tuberculosis 10,6% fueron multidrogoresistentes (MDR) y 2,12% con resistencia extendida (XDR). Mycobacterium avium y M. abscessus fueron las MNT más frecuentes. La mortalidad general fue 10%. Conclusiones: Inmuno-supresión es el principal factor de riesgo para enfermedad extrapulmonar y/o diseminada y la resistencia a fármacos en pacientes hospitalizados con TBC es llamativa, con mayor incidencia de MDR y XDR. Las infecciones por MNT no son infrecuentes en nuestro medio.
