La linfocitopenia T CD4 idiopática (LCI) es un síndrome clínico inusual que se caracteriza por un déficit de células T CD4+ circulantes en ausencia de infección por VIH u otra condición de inmunosupresión. Los pacientes con dicha enfermedad pueden presentarse asintomáticos o con infecciones oportunistas, las más frecuentes son por criptococo, micobacterias o virales como herpes zoster. Presentamos el caso de un hombre de 32 años, sin antecedentes, en quien se descartó infección por retrovirus, con recuento de linfocitos T CD4+ menor a 300 células/m3; se diagnosticó LCI posterior al diagnóstico de criptococomas cerebrales mediante hallazgos imagenológicos los cuales fueron congruentes con estudios microbiológicos.

Background Palmoplantar hyperkeratosis is a cutaneous manifestation that had not been clearly associated with infection by the human T-cell lymphotropic virus, which is a retrovirus that in most cases does not develop clinical pathologies and its symptoms may be undetected. The skin is one of the most affected organs, however until now only seborrheic dermatitis, xerosis/ichthyosis and infective dermatitis associated with HTLV-1 have been described as cutaneous clinical manifestations of this disease. Case presentation We present the case of a 36-year-old male patient with serologically documented HTLV-1 infection, who presented symptoms of diarrhea, malabsorption due to Strongyloides stercoralis, and in whom a physical examination revealed an association with generalized xerosis and palmoplantar keratoderma confirmed by skin biopsy. Other infectious etiologies and malignancy were ruled out. This clinical manifestation was managed with dermal hydration, and skin care which improved the thickened skin and make it less noticeable. Conclusions According to our experience, this is the first reported case of palmoplantar keratoderma associated with a human lymphotropic virus infection. This is a skin manifestation that has not been confirmed in conjunction with HTLV-I before. This implies that palmoplantar keratoderma is a new clinical manifestation of this infection, that should be considered in the initial approach of patients in endemic areas with these dermatological characteristics.

Introduction: Massive bleeding in civilian trauma patients leads to dilutional coagulopathy. Transfusion with high plasma:red blood cell (RBC) ratio has been effective in reducing mortality in war trauma patients. However, in civilian trauma the evidence is controversial. Objective: To assess the impact on mortality of high vs low plasma:RBC ratio transfusion, in civilian trauma patients with massive bleeding. Methods: A systematic review and meta-analysis, including observational studies and clinical trials, was conducted. Data bases were systemically searched for relevant studies between January 2007 and June 2019. The main outcome was early (24-hours) and late (30-day) mortality. Fixed and random effects models were used. Results: Out of 1295 studies identified, 33 were selected: 2 clinical trials and 31 observational studies. The analysis of observational trials showed both decreased early mortality (odds ratio [OR] 0.67; 95% confidence interval [CI], 0.60-0.75) and late mortality (OR 0.79; 95% CI, 0.71-0.87) with the use of high plasma:RBC ratio transfusion, but there were no differences when clinical trials were evaluated (OR 0.89; 95% CI, 0.64-1.26). The exclusion of patients who died within the first 24 hours was a source of heterogeneity. The Injury Severity Score (ISS) altered the association between high plasma:RBC ratio and mortality, with a reduced protective effect when the ISS was high. Conclusion: The use of high vs low plasma: RBC ratio transfusion, in patients with massive bleeding due to civil trauma, has a protective effect on early and late mortality in observational studies. The exclusion of patients who died within the first 24 hours was a source of heterogeneity. Resumen Introducción: El sangrado masivo en los pacientes con trauma civil propicia el desarrollo de coagulopatía dilucional. La transfusión de plasma y glóbulos rojos con una relación alta ha sido efectiva para disminuir la mortalidad en pacientes con trauma de guerra; sin embargo, su evidencia en trauma civil es controversial. Objetivo: Evaluar el efecto sobre la mortalidad de la transfusión de plasma: glóbulos rojos con relación alta (TPGR-RA) versus baja, en pacientes con sangrado masivo por trauma civil. Métodos: Se realizó una revisión sistemática y metaanálisis de estudios observacionales y experimentos clínicos publicados en el periodo de enero de 2007 a junio de 2019. El desenlace principal fue mortalidad temprana (24 horas) y tardía (30 días), utilizando el modelo de efectos fijos y aleatorios. Resultados: De 1.295 estudios identificados se incluyeron 33: dos experimentos clínicos y 31 estudios observacionales. El uso de TPGR-RA mostró una disminución de la mortalidad temprana (OR 0,67; IC 95 %, 0,60-0,75) y tardía (OR 0,79; IC 95 %, 0,71-0,87) cuando se analizaron los estudios observacionales, pero no hubo diferencias cuando se evaluaron los experimentos clínicos (OR 0,89; IC 95 %, 0,64-1,26). La exclusión de pacientes que fallecieron en las primeras 24 horas fue una fuente de heterogeneidad. La gravedad del trauma, ISS (por las iniciales en inglés de injury severity score)modificó la asociación entre la TPGR-RA y mortalidad, siendo menor el efecto protector cuando el ISS era alto. Conclusiones: El uso de TPGR-RA en pacientes con trauma civil y transfusión masiva (TM) tiene efecto protector sobre la mortalidad en los estudios observacionales. La exclusión de pacientes fallecidos en las primeras 24 horas fue causa de heterogeneidad.

Introduction: Heart failure is a chronic, progressive, prevalent disease, with a high impact on health systems and on the quality of life of patients and families. Dyspnea is a common symptom and management with opioids has been proposed. Objective: To conduct a systematic review of the literature pertaining to the use of opioids for the management of dyspnea in patients with stable chronic heart failure, functional class New York Heart Association (NYHA) II, III, or IV. Materials and methods: A systematic review was conducted in the MEDLINE, Embase, Cochrane, OVID, LILACS, and PROSPERO databases of articles published in 5 languages between January 1, 1995 and July 31, 2018. Studies describing the administration of any type of opioid for the management of dyspnea in patients with stable chronic heart failure NYHA II, III, or IV were included. Results: Four clinical trials were obtained for the final analysis with a total number of 70 patients, describing opioid administration for the management of dyspnea in patients with stable chronic heart failure, NYHA II, III, or IV. Conclusion: In adult patients with compensated chronic heart failure under optimum treatment, there is low-quality evidence that shows benefit with the use of opioids for the management of dyspnea. For a stronger recommendation, controlled, randomized studies with a larger number of subjects are required.

Systemic lupus erythematosus is an autoimmune disease that involves several systems, affects mainly young adult women, and causes a significant deterioration in quality of life. Different environmental aspects are known to facilitate the development of lupus in predisposed individuals. For several years it has been known that factors such as exposure to UV rays are related to the development of lupus; however, due to factors inherent to globalization, life-style changes, improved knowledge of cell signaling pathways as well as a better understanding of metabolomics, proteomics an genomics, it has been possible to better understand the relationship between cells and their environment. This study based on a narrative review, compiles the existing evidence on different risk factors and the development of lupus, including aspects typical of the Colombian population. RESUMEN El lupus eritematoso sistémico es una enfermedad autoinmune que compromete diferentes sistemas, afecta principalmente a mujeres adultas jóvenes y genera un deterioro significativo de la calidad de vida. Es bien conocido que diferentes aspectos relacionados con la calidad de vida facilitan el desarrollo del lupus en individuos predispuestos. Desde hace varios años se sabe que factores tales como la exposición a los rayos ultravioleta se relacionan con el desarrollo de lupus; sin embargo, debido a factores inherentes a la globalización, a los cambios en los hábitos, a un mayor conocimiento de las vías de señalización celular, así como a una mayor comprensión de la metabolómica, la proteómica y la genómica, ha sido posible entender mejor la relación entre las células y su medio ambiente. En el presente estudio reunimos, a través de una revisión narrativa, la evidencia actual sobre diferentes factores de riesgo y el desarrollo del lupus, incluyendo aspectos típicos de la población colombiana.

Introduction The envenomation by Lonomia species mainly occur in rural areas. The main symptom of this condition is an alteration in the clotting times and hemorrhage. However, acute kidney injury is been also identified in some case reports. Therefore, it should not be disregarded and to understand the pathophysiological mechanism, diagnosis and treatment of this clinical feature results necessary in order to expand awareness and to prevent further medical complications and death. Materials and Methods We present a case report and scoping review of the literature to characterize patients with acute kidney injury secondary to Lonomia envenomation by a case report and describing the pathophysiology, diagnosis, treatment and prognosis of patients suffering from this condition. The information was obtained from 4 databases: Medline, Embase, LILACs and Ovid. We used the following search strategy: (((“Acute Kidney Injury” [Mesh]) AND “lonofibrase” [Supplementary Concept]) OR lonomy accident) OR lonomia. Results We identified ten case reports of Lonomia spp. Envenomation, nine of them were caused by L. obliqua and one by L. achelous. A cohort study that included 37 patients who were exposed to the L. obliqua venom was also included. All patients were adults, lived in the countryside and developed acute kidney injury. Conclusions Acute kidney injury has been identified as one important clinical feature of the Lonomia envenomation. The development of this condition is mediated by various pathophysiological mechanisms. To perform an adequate diagnosis, coagulation times, fibrinogen levels, hemogram, kidney function and urinalysis should be done. The definitive treatment depends on the type of envenomation. The prognosis for these patients is not well described yet. However, our patient had a good response to the described management given.

Resumen Introducción: En presencia de bloqueo de la rama izquierda, el infarto agudo de miocardio (IAM) es un reto diagnóstico para el médico. Objetivo: Evaluar la utilidad de los criterios de Sgarbossa en el diagnóstico de IAM en pacientes con bloqueo de la rama izquierda mediante una revisión sistemática y metaanálisis. Método: Búsqueda estructurada de la literatura en Medline, Lilacs, Ovid y Embase, desde enero 1996 hasta enero de 2018. Basados en los criterios de inclusión y exclusión, tres revisores seleccionaron los artículos que respondieran la pregunta de investigación. La calidad de los artículos se evaluó con el instrumento QUADAS-2. Resultados: Catorce estudios evaluaron los criterios de Sgarbossa utilizando un puntaje mayor o igual a 3 como corte. En total, fueron 3689 pacientes. La sensibilidad fue de 0,27 (IC95 %: 0,24-0,29; p = 0,0000); especificidad de 0,97 (IC95 %: 0,96-0,98; p = 0,0001) LR(+) de 10,95 (6,28-19,11; p = 0,03) y LR(–) de 0,67 (0,56-0,81; p = 0,0000). Conclusiones: Los criterios de Sgarbossa tienen una alta especificidad para el diagnóstico de IAM con bloqueo de la rama izquierda; pero bajo LR(–) y sensibilidad. Se deben evaluar nuevos algoritmos diagnósticos y validar para la población colombiana. Abstract Introduction: Acute myocardial infarction (AMI) in the presence of left bundle branch block (LBBB) is a diagnostic challenge for the physician. The purpose of this article is to evaluate the usefulness of the Sgarbossa criteria for the diagnosis of AMI in patients with LBBB through a systematic review and meta-analysis. Method: Structured literature search in Medline, Lilacs, Ovid, and Embase from January 1996 to January 2018. Using the inclusion and exclusion criteria 3 reviewers selected the articles that answered the research question. The quality of the articles was evaluated using the QUADAS-2 tool. Results: 14 studies evaluated the Sgarbossa criteria using a score ≥ 3 points. With a total of 3689 patients, the sensitivity was 0.27 (95% CI: 0.24-0.29; p = 0.0000); specificity of 0.97 (95% CI: 0.96-0.98; p = 0.0001) LR(+) was 10.95 (6.28-19.11; p = 0.03), and LR(–) was 0.67 (0.56-0.81; p = 0.0000). Conclusions: The Sgarbossa criteria have a high specificity for the diagnosis of AMI with LBBB; however, the sensitivity and the LR(–) are low. It is necessary to evaluate new diagnostic algorithms and to validate the criteria for Colombia.

La vasculitis leucocitoclastica es una patologìa que compromete los vasos pequeños y cuya causa predominantemente se ha descrito como idiopatica. Se presenta el caso de una mujer de 78 años hipertensa, diabética y con enfermedad renal crónica en estadio 5, que presentó lesiones limitadas a la piel posterior a la administración de oxacilina para manejo de bacteremia por SAMS. La presentación clínica se basó en purpuras palpables predominantemente en miembros inferiores y lesiones dolorosas coalescentes que formaban ampollas de contenido hemorrágico. Estas lesiones resolvieron gradualmente después del cambio de la terapia mencionada anteriormente. La biopsia fue compatible con vasculitis leucocitoclástica, con paraclínicos que descartaron causas infecciosas y autoinmunes.
