ABSTRACT

ABSTRACT Background: Multiple myeloma is a disease of the elderly. However, 40% of patients are diagnosed before 65 years old. Outcomes regarding age as a prognostic factor in MM are heterogeneous. Method: We retrospectively analyzed clinical characteristics, response to treatment and survival of 282 patients with active newly-diagnosed multiple myeloma, comparing results between patients younger and older than 65 years. Main results: The frequency of multiple myeloma in those younger than 66 years was 53.2%. Younger patients presented with a more aggressive disease, more advanced Durie-Salmon stage (85.3% vs 73.5%; p = 0.013), extramedullary disease (12.7% vs 0%; p < 0.001), osteolytic lesions (78.7% vs 57.6%; p < 0.001) and bone plasmacytoma (25.3% vs 11.4%; p = 0.003). In spite of this, the overall response rate was similar between groups (80.6% vs 81.4%; p = 0.866). The overall survival was significantly longer in young patients (median, 65 months vs 41 months; p = 0.001) and higher in those who received autologous hematopoietic stem cell transplantation. The main cause of death was disease progression in both groups. Multivariable analysis revealed that creatinine ≥2 mg/dl, extramedullary disease, ≤very good partial remission and non-autologous hematopoietic stem cell transplantation are independent risk factors for shorter survival. Conclusion: Although multiple myeloma patients younger than 66 years of age have an aggressive presentation, this did not translate into an inferior overall survival, particularly in those undergoing autologous hematopoietic stem cell transplantation.

ABSTRACT

Introduction: Leishmaniasis is a tropical and subtropical disease highly reported in Southeast Asia, East Africa, Latin America, and the Mediterranean basin, with an incidence of two million new cases by year and 500,000 cases of visceral leishmaniasis. One of the more severe and rare complications of visceral leishmaniasis is hemophagocytic lymphohistiocytosis. Objective: To describe the clinical characteristics of hemophagocytic lymphohistiocytosis associated with visceral leishmaniasis Methods: We performed a literature review based on the case reports indexed in MEDLINE/PubMed. Results: Twenty-five cases were included; 52 percent under two years of age. All cases presented splenomegaly and 84 percent hepatomegaly. Cytopenias were described in all patients: 100 prcent thrombocytopenia, 96 percent anemia, and 84 percent leukopenia or neutropenia. Hypertriglyceridemia and hypofibrinogenemia were found in 68 percent and 32 percent, respectively, and hyperferritinemia in 80 percent. Additionally, hemophagocytosis was documented in 84 percent, with Leishmania detection in 92 percent. All patients were treated against Leishmania: 80% with liposomal amphotericin B. regarding the treatment for hemophagocytic lymphohistiocytosis; corticosteroid were used in 36 percent, endovenous immunoglobulin in 28 percent, cyclosporine in 28 prcent and etoposide in 16 percent The complications reported included gastrointestinal hemorrhage (8 percent), disseminated intravascular coagulation (8 percent), autoimmune hemolytic anemia (12 percent), multiple-organ dysfunction/septic shock (12 prcent), petechial rash (16 percent), and four patients deceased. Variables such as fever (p=0.031), hemoglobin level (p=0.031), platelet count (p=0.0048), and ferritin (p=0.0072) were associated with mortality Conclusions: During visceral leishmaniasis, the hemophagocytic syndrome is a rare condition that mainly affects pediatric patients, but with excellent outcomes using liposomal amphotericin B. However, there is a lack of strong evidence to make a recommendation(AU)


Introducción: La leishmaniasis es una enfermedad tropical y subtropical con una elevada incidencia, dos millones de casos nuevos por año y 500 000 de leishmaniasis visceral. La linfohistiocitosis hemofagocítica es una complicación grave y rara de la leishmaniasis visceral. Objetivo: Describir las características clínicas de la linfohistiocitosis hemofagocítica asociada con leishmaniasis visceral. Métodos: Se realizó una revisión bibliográfica basada en los informes de casos indexados en MEDLINE/PubMed. Se identificaron 34 publicaciones; después de analizarlas en función de los criterios de inclusión se trabajó con 22 trabajos. Resultados: En los trabajos incluidos se informaron 25 casos; el 52 por ciento fueron pacientes menores de 2 años. Todos presentaron esplenomegalia y 84 por ciento hepatomegalia. Se describieron citopenias en todos los pacientes: 100 por ciento trombocitopenia, 96 por ciento anemia y 84 por ciento leucopenia o neutropenia. Se encontró hipertrigliceridemia e hipofibrinogenemia en 68 por ciento y 32 por ciento, respectivamente, e hiperferritinemia en 80 por ciento. Todos los pacientes fueron tratados contra leishmania, 80 por ciento con anfotericina B liposomal. Las complicaciones incluyeron: hemorragia gastrointestinal, coagulación intravascular diseminada, anemia hemolítica autoinmune, falla multiorgánica/shock séptico, erupción petequial y cuatro pacientes fallecieron. Conclusiones: En la leishmaniasis visceral, el síndrome hemofagocítico es una afección poco frecuente que afecta principalmente a pacientes pediátricos. Para el tratamiento, usando la anfotericina B liposomal se obtienen excelentes resultados; sin embargo, la evidencia es insuficiente para hacer una recomendación(AU)

ABSTRACT

Resumen La enfermedad renal crónica es un problema de salud pública con una alta morbilidad y mortalidad. El trasplante renal es una de las actuales alternativas terapéuticas. Se incluyen en este artículo 12 trabajos publicados referentes a la contaminación del líquido de preservación en trasplante renal, 4 reportes de caso, y 8 estudios de prevalencia. En este estudio la prevalencia de contaminación de líquido de preservación para cualquier microorganismo varió entre 17,43 % a 59,72 %, mientras que para los limitados al reporte de Candida sp, la frecuencia varió de 1,69 % a 8,57 %. En los reportes de caso, todos fueron asociados a la infección por Candida sp, con arteritis de la arteria renal y pérdida del injerto como las complicaciones más frecuentes. En nuestra institución, Hospital de Especialidades de las Fuerzas Armadas N°1, de un total de 59 pacientes trasplantados se aisló al menos un microorganismo en 20 casos (28,17 %). Con estos resultados sugerimos que la contaminación del líquido de preservación es un fenómeno frecuente en trasplante renal, sin embargo al no poseer publicaciones en las que se describan las complicaciones asociadas a la infección por otros microorganismos, creemos que la contaminación por Candida sp, a pesar de no tener una gran frecuencia, es clínicamente la más relevante.


Abstract Chronic kidney disease is a public health problem with high morbidity and mortality, kidney transplantation being one of the current therapeutic alternatives. In12 published works concerning the contamination of the preservation fluid in kidney transplant, four case reports, and eight prevalence studies. The prevalence of preservation liquid contamination for any microorganism ranged from 17.43% to 59.72%, while for those limited to the Candida sp report, the frequency varied from 1.69% to 8.57%. In the case reports, all were associated with Candida infection, with renal artery arteritis and graft loss as the most frequent complications. In our institution, of a total of 59 transplant patients, at least one microorganism was isolated in 20 cases (28.17%). Preservation fluid contamination is a frequent phenomenon in kidney transplantation. However, since no publications are describing the complications associated with infection by other microorganisms, we could say that contamination by Candida sp, despite not having a high prevalence, it is clinically the most relevant.

ABSTRACT

Resumen Introducción: la anemia y ferropenia son condiciones muy prevalentes en hemodiálisis asociadas al incremento en la morbimortalidad. Objetivo: describir las características de la ferropenia y anemia de pacientes con enfermedad renal terminal en hemodiálisis, y analizar los parámetros del hemograma para predecir la deficiencia de hierro en ellos. Materiales y métodos: estudio descriptivo transversal realizado en la unidad de hemodiálisis del Hospital de Especialidades de las Fuerzas Armadas N°1 y CLINEF Norte, Quito, Ecuador, durante diciembre de 2018 y enero de 2019. El análisis se basó en la comparación de dos grupos, pacientes ferropénicos y no ferropénicos. Resultados: se incluyeron 268 pacientes con edad promedio de 16 y 59 años; 89 pacientes (33,21 %) fueron ferropénicos, sin embargo presentaron parámetros hematimétricos normales en la mayoría de ellos. Encontramos además que el 80,22 % de los pacientes incluidos eran anémicos, con poca frecuencia de microcitosis e hipocromía. Entre ellos, el 33,21 % fueron ferropénicos, siendo la hemoglobina un pobre marcador de ferropenia. Adicionalmente, para predecir ferropenia, y de no contar con ferritina o saturación de transferrina, encontramos útil la hemoglobina corpuscular media, el volumen corpuscular medio, el ancho de distribución eritrocitaria y el índice de Srivastava, sin embargo el valor predictivo se incrementó al incluir la sideremia como en nuestro modelo propuesto. Conclusiones: dada la alta frecuencia de anemia sin hipocromía o microcitosis en los pacientes con enfermedad renal terminal en hemodiálisis, incluso en ferropenia, es fundamental la evaluación regular del metabolismo férrico, así como el análisis del hemograma con enfoque en el paciente dialítico.


Abstract Introduction: Anemia and iron deficiency are very prevalent conditions in hemodialysis and have been associated with an increase in morbidity and mortality. Objective: Describe the characteristics of iron deficiency and anemia in patients with end-stage renal disease on hemodialysis, and analyze the parameters of the blood count to predict iron deficiency in them. Materials and methods: A cross-sectional descriptive study carried out in the hemodialysis unit of the Specialties Hospital of the Armed Forces No. 1 and CLINEF Norte, Quito, Ecuador, during December 2018 and January 2019. The analysis was based on the comparison of two groups, ferropenic and non-ferropenic patients. Results: We included 268 patients with an average age of 59.16 years; 89 patients (33.21%) were ferropenic. However, they presented normal hematimetric parameters in most of them. We also found that 80.22% of the patients included were anemic, with little frequency of microcytosis and hypochromia. Among them, 33.21% were ferropenic, being hemoglobin a poor marker of iron deficiency. Additionally, to predict ferropenia, and not to have ferritin or transferrin saturation, we find especially useful the mean corpuscular hemoglobin, mean corpuscular volume, erythrocyte distribution width, and Srivastava index, however the predictive value increases when including the syderemia as in our proposed model. Conclusions: Given the high frequency of anemia without hypochromia or microcytosis in patients with end-stage renal disease on hemodialysis, even in iron deficiency, regular evaluation of ferric metabolism is essential, as well as the analysis of the blood count with a focus on the dialysis patient.

ABSTRACT

Abstract: Background: Urinary tract infections (UTI) are among the most common infections in pediatric patients. The main etiopathogenic agent is Escherichia coli. The purpose of this study was to determine the antimicrobial resistance pattern of E. coli in pediatric patients and to understand their main clinical and laboratory manifestations. Methods: Fifty-nine patients were included in the study and classified into two groups: hospitalization (H) and external consultation (EC). Every patient presented urine cultures with the isolation of E. coli that included an antibiogram. Clinical signs and symptoms, urinalysis, complete blood count (CBC) and serum inflammatory markers were analyzed. Results: The most common clinical manifestations were fever (H: 76.5%; EC: 88%), vomiting (H: 32.4%; EC: 32%), hyporexia (H: 20.6%; EC: 16%), abdominal pain (H: 20.6%: EC: 28%), and dysuria (H: 14.7%; EC: 32%). Ten patients (16.95%) presented UTI for extended spectrum beta-lactamase (ESBL) E. coli. Ampicillin, nalidixic acid, and trimethoprim-sulfamethoxazole showed a higher resistance rate, being ampicillin the most significant (H: 88.2%; EC: 92%). Leukocyturia, bacteriuria and urine nitrites were frequent alterations in urinalysis (H: 52.9%; EC: 92%). In ESBL E. coli patients, a positive correlation was found between leukocytes in CBC and C-reactive protein (r = 0.9, p < 0.01). Diarrhea and foul-smelling urine were associated with E. coli resistance. Conclusions: The presence of leukocytes, bacteria, nitrites and the Gram stain are the most common indicators. Nitrofurantoin and phosphomycin are good therapeutic options. However, an antibiogram must be conducted to determine the best therapeutic agent.


Resumen: Introducción: Las infecciones de tracto urinario (ITU) se encuentran entre las más frecuentes en pediatría, siendo Escherichia coli el principal agente etiopatogénico. El objetivo de este estudio fue determinar el patrón de resistencia antimicrobiana de E. coli en pacientes pediátricos y conocer sus principales manifestaciones clínicas y de laboratorio. Métodos: Se incluyeron en el estudio 59 pacientes en dos grupos: hospitalización (H) y consulta externa (CE). En cada uno se realizó un urocultivo y un antibiograma con aislamiento de E. coli. Se analizaron signos y síntomas, uroanálisis, hemograma y marcadores séricos de inflamación. Resultados: Las manifestaciones clínicas más frecuentes fueron fiebre (H: 76.5%; CE: 88%), vómito (H: 32.4%; CE: 32%), hiporexia (H: 20.6%; CE: 16%), dolor abdominal (H: 20.6%: CE: 28%) y disuria (H: 14.7%; CE: 32%). Diez pacientes (16.95%) presentaron ITU por E. coli beta-lactamasa de espectro extendido (BLEE). La ampicilina, ácido nalidíxico y trimetroprim con sulfametoxazol mostraron alta resistencia, siendo ampicilina la más significativa (H: 88.2%, CE: 92%). Leucocituria, bacteriuria y nitritos en orina fueron frecuentes en el uroanálisis. En pacientes con E. coli BLEE se encontró una correlación positiva entre los leucocitos y la proteína C reactiva (r = 0.9, p < 0.01). La diarrea y el mal olor en la orina se asociaron con resistencia de E. coli. Conclusiones: La leucocituria, la bacteriuria, los nitritos y la tinción Gram son los indicadores más frecuentes de ITU. La nitrofurantoina y fosfomicina son buenas opciones terapéuticas. Sin embargo, debe realizarse un antibiograma para determinar el mejor tratamiento.

ABSTRACT

La necesidad de una reconstrucción mandibular está dictada por la pérdida de hueso debido, entre otras causas, a trauma. El propósito de este trabajo es caracterizar un caso de reconstrucción mandibular de una deformidad posquirúrgica por trauma. Se trata de un paciente masculino de 34 años que acude a consulta por inconformidad estética y dificultad para masticar. Aproximadamente un año atrás había padecido un trauma facial, por lo cual fue atendido de urgencia e intervenido quirúrgicamente. Se realizó estabilización ósea y colocación de placa de reconstrucción mandibular. Presentaba asimetría facial, disminución del tercio inferior facial y movilidad de los segmentos óseos mandibulares, por tal motivo se decide realizar retirada de la placa existente, reacomodamiento de los segmentos óseos, colocación de injerto autólogo de cresta ilíaca y fijación. Se observó buena evolución posoperatoria. La repercusión estética y funcional, en un paciente joven con una deformidad posquirúrgica por trauma; motivó el planeamiento de una reconstrucción mandibular mediante placa rígida e injerto de creta ilíaca. El tratamiento de este caso constituyó un reto profesional por tratarse de una deformidad posquirúrgica provocada por un trauma de alta energía; pero el trabajo quirúrgico en equipo aseguró resultados satisfactorios(AU)


The need for mandibular reconstruction is dictated by bone loss due to trauma among other causes. The purpose of the study was to present a case of mandibular reconstruction of a post-surgical deformity due to trauma. A 34-year-old male patient presents with dissatisfaction with his dentofacial appearance and difficulty chewing. About one year before he had undergone facial trauma, for which had been cared for at the emergency service and had been operated on. Bone stabilization was performed as well as placement of a mandibular reconstruction plate. The patient presented facial asymmetry, a diminished lower facial third and mobility in mandibular bone segments. Therefore, it was decided to perform removal of the existing plate, rearrangement of the bone segments, placement of an autologous iliac crest bone graft and surgical fixation. Good post-operative evolution was observed. Esthetic and functional impairment in a young patient with a post-surgical deformity due to trauma led to planning a mandibular reconstruction with a rigid plate and an iliac crest graft. Treatment in this case was professionally challenging, for the post-surgical deformity had been due to high energy trauma, but the surgical work performed ensured satisfactory results(AU)

ABSTRACT

BACKGROUND AND OBJECTIVE: Ischemic heart disease affects a high number of patients, and may be treated by surgery or coronary angioplasty. The objective of this study is to compare the middle term results of both procedures. MATERIAL AND METHODS: Between January and March of 1999, 59 patients with a mean age of 65 years old ranging 46 to 79, were treated with myocardial revascularization (group I) and 57 patients with a mean age of 59 years old ranging 33 to 88 were submitted to coronary angioplasty (group II). It was evaluated and compared risk factors, morbidity, mortality, evolution in two years after the procedures, presence of symptoms, freedom of events. RESULTS: In group I a higher number of diabetic patients was found. The 89.8 of patients was asymptomatic two years after the procedure in group I against 52.6 in group II (p = 0.03). One patient in group I presented angina six months after the procedure and 27 patients in group II (47.3), presented angina between the first seven months after the procedure (p = 0.034). Morbidity affects in special to diabetic patients and was higher in group I. Mortality was similar in both groups: 6.7 for group I and 6 in group II. The length of stay in hospital was lower in group II (p = 0.03). CONCLUSION: In a middle time, coronary artery bypass grafting offers better results related to freedom of angina and better quality of life.
