Linfangiomatosis esplénica en un paciente adulto: Reporte de caso

Los linfangiomas son malformaciones benignas del sistema linfático que afectan con mayor frecuencia a los niños y en raras ocasiones a adultos. Presentamos el caso de una mujer de 36 años, con cuadro clínico de 6 meses de dolor abdominal difuso sin irritación peritoneal, y asociado a adinamia. Como parte de los estudios, se solicitó una tomografía axial computarizada con contraste de abdomen, que reveló múltiples lesiones esplénicas hipodensas hipovasculares, con sospecha diagnóstica de lesiones linfoproliferativas. Por tal motivo se solicitó una esplenectomía diagnóstica, que finalmente mostró hallazgos macroscópicos, microscópicos y de inmunohistoquímica (positividad de las lesiones quísticas para CD31 y D2-40) compatibles con linfagiomatosis esplénica difusa.

Lymphangiomas are benign malformations of the lymphatic system. They most often affect children and rarely adults. We present the case of a 36-year-old woman with a 6-month clinical picture of diffuse abdominal pain without peritoneal irritation associated with adynamia. As part of the studies, a computerized axial tomography with abdominal contrast was requested, which revealed multiple hypovascular hypodense splenic lesions with suspected diagnosis of lymphoproliferative lesions. For this reason, a diagnostic splenectomy was requested, which showed macroscopic, microscopic and immunohistochemical findings (positivity of cystic lesions for CD31 and D2-40) compatible with diffuse splenic lymphagiomatosis

Pigmentación violácea dolorosa, reto clínico y enfoque diagnóstico en un país tropical / Painful violaceous pigmentation, a clinical challenge and diagnostic approach in a tropical country

RESUMEN Contrario a lo que se cree, los milpiés no se consideran animales venenosos, su mecanismo de defensa puede resultar perjudicial para el ser humano, manifestándose como lesiones de carácter eritematoso, purpúrico y cianótico, concomitante dolor local y parestesia; Según la exposición, el cuadro clínico puede evolucionar a lesiones moderadas y severas, ampollas y úlceras. Describimos el caso de un paciente pediátrico de sexo masculino de la región andina de Colombia, con temperaturas diarias que oscilan entre 15° y 30°C y una humedad promedio de 72 %, quien accidentalmente pisó un milpiés, lo cual fue un desafío diagnóstico entre el personal de salud que generó su atención.

ABSTRACT Millipedes are not considered poisonous animals, although in some cases their chemical defense mechanisms may be deleterious for human beings, manifesting as erythematous, purpuric and/ or cyanotic lesions alongside local pain and paresthesia. According to the exposure, the clinical condition may progress to moderate and severe lesions such as ulcers and blisters. We describe a case of a male child from the Andean region in Colombia, an area with daily temperatures between 15° and 30° C and 72% average humidity. The boy accidentally stepped on a millipede, and this occurrence became a challenge for its diagnosis amongst staff who provided emergency health care.

Predicting sepsis severity at first clinical presentation: The role of endotypes and mechanistic signatures.

BACKGROUND: Inter-individual variability during sepsis limits appropriate triage of patients. Identifying, at first clinical presentation, gene expression signatures that predict subsequent severity will allow clinicians to identify the most at-risk groups of patients and enable appropriate antibiotic use. METHODS: Blood RNA-Seq and clinical data were collected from 348 patients in four emergency rooms (ER) and one intensive-care-unit (ICU), and 44 healthy controls. Gene expression profiles were analyzed using machine learning and data mining to identify clinically relevant gene signatures reflecting disease severity, organ dysfunction, mortality, and specific endotypes/mechanisms. FINDINGS: Gene expression signatures were obtained that predicted severity/organ dysfunction and mortality in both ER and ICU patients with accuracy/AUC of 77-80%. Network analysis revealed these signatures formed a coherent biological program, with specific but overlapping mechanisms/pathways. Given the heterogeneity of sepsis, we asked if patients could be assorted into discrete groups with distinct mechanisms (endotypes) and varying severity. Patients with early sepsis could be stratified into five distinct and novel mechanistic endotypes, named Neutrophilic-Suppressive/NPS, Inflammatory/INF, Innate-Host-Defense/IHD, Interferon/IFN, and Adaptive/ADA, each based on ∼200 unique gene expression differences, and distinct pathways/mechanisms (e.g., IL6/STAT3 in NPS). Endotypes had varying overall severity with two severe (NPS/INF) and one relatively benign (ADA) groupings, consistent with reanalysis of previous endotype studies. A 40 gene-classification tool (accuracy=96%) and several gene-pairs (accuracy=89-97%) accurately predicted endotype status in both ER and ICU validation cohorts. INTERPRETATION: The severity and endotype signatures indicate that distinct immune signatures precede the onset of severe sepsis and lethality, providing a method to triage early sepsis patients.

Linfadenopatía reactiva por vacuna Pfizer-BioNTech para COVID-19: reporte de un caso / Reactive lymphadenopathy due to Pfizer-BioNTech COVID-19 vaccine: a case report

Uno de los efectos secundarios encontrados en pacientes con antecedente de vacunación por COVID-19, especialmente con la vacuna Pfizer-BioNTech, es la aparición de múltiples adenopatías hiperplásicas, principalmente en los ganglios linfáticos axilares, supraclaviculares e infraclaviculares ipsilaterales al sitio de vacunación. Presentamos el caso de una paciente femenina de 33 años, con aparición de masa dolorosa supraclavicular izquierda, quien una semana antes había sido vacunada con la primera dosis de la vacuna Pfizer-BioNTech en región deltoidea izquierda. Los hallazgos citológicos fueron sugestivos de una enfermedad linfoproliferativa, y el estudio histopatológico reveló linfadenopatía reactiva con proliferación de inmunoblastos B activados, secundaria a la vacunación contra COVID-19. Aportamos a la literatura con la caracterización de los hallazgos histopatológicos de la linfadenopatía posvacunación contra COVID-19. Es importante que los médicos tratantes y radiólogos estén familiarizados con este diagnóstico diferencial, para brindar recomendaciones adecuadas basadas en un seguimiento a corto plazo, en lugar de realizar biopsias, intervenciones y conductas inmediatas innecesarias en el manejo de los pacientes

One of the side effects found in patients with a history of vaccination for COVID-19, especially with the Pfizer-BioNTech vaccine, is the appearance of multiple hyperplastic adenopathies, mainly axillary, supraclavicular and infraclavicular lymph nodes ipsilateral to the vaccination site. We present the case of a 33-year-old female patient, with the appearance of a painful left supraclavicular mass, who was vaccinated a week earlier with the first dose of the Pfizer-BioNTech vaccine in the left deltoid region. The cytological findings were suggestive of a lymphoproliferative disease, and the histopathological study revealed reactive lymphadenopathy with proliferation of activated B immunoblasts, secondary to vaccination against COVID-19. We contribute to the literature with the characterization of the histopathological findings of COVID-19 post-vaccination lymphadenopathy. It is important for treating physicians and radiologists to be familiar with this differential diagnosis, in order to provide appropriate recommendations based on short-term follow-up, instead of performing unnecessary immediate biopsies or interventions in patient management.

Scleredema Diabeticorum / Escleredema Diabeticorum Scleredema Diabeticorum

Abstract Scleredema diabeticorum is one of the skin disorders associated with diabetes mellitus, characterized by thickening of the deep layers of the dermis, with excessive mucin and collagen deposition, clinically evidenced in hardening of the skin, especially in the upper half of the body. We describe the clinical case of an adult male diabetic who was seen for an indurated cervical lesion which was subsequently diagnosed histopathologically as scleredema diabeticorum. The interest in this case lies in the low prevalence of the condition and its association with poor metabolic control of diabetes. (Acta Med Colomb 2021; 46. DOI:https://doi.org/10.36104/amc.2021.1888).

Resumen Dentro de los trastornos cutáneos asociados a la diabetes mellitus, se describe el escleredema diabeticorum el cual se caracteriza por un engrosamiento de las capas profundas de la dermis con depósito excesivo de mucina y colágeno, que produce clínicamente endurecimiento de la piel, principalmente en la mitad superior del cuerpo. Se describe un caso clínico correspondiente a un hombre adulto diabético que consultó por la aparición de una lesión indurada en la región cervical con posterior diagnóstico histopatológico de escleroderma diabeticorum. El interés radica en la baja prevalencia de la condición y su asociación al pobre control metabólico de la diabetes. (Acta Med Colomb 2021; 46. DOI:https://doi.org/10.36104/amc.2021.1888).

Dengue and COVID-19, overlapping epidemics? An analysis from Colombia.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread throughout Latin America, a region swept by multiple previous and ongoing epidemics. There are significant concerns that the arrival of COVID-19 is currently overlapping with other viruses, particularly dengue, in various endo-epidemic regions across South America. In this report, we analyzed trends for both viral infections in Colombia during the first 20 epidemiological weeks (EWs) of 2020. From 1st January to 16th May 2020 (EWs, 1-20), a total of 52 679 cases of dengue and 14 943 cases of COVID-19 have been confirmed in Colombia. As both conditions may potentially lead to fatal outcomes, especially in patients with chronic co-morbidities, overlapping infections, and co-occurrence may increase the number of patients requiring intensive care and mechanical ventilation. In regions, such as Valle del Cauca, intensified preparation for such scenarios should be pondered, and further studies should be performed to address this critical issue in a timely matter.

Quantifying the Economic Impact of Bovine Tuberculosis on Livestock Farms in South-Western Spain.

Pasture-based livestock farming generates income in regions with limited resources and is key to biodiversity conservation. However, costs derived from fighting disease can make the difference between profit and loss, eventually compromising farm survival. Animal TB (TB), a chronic infection of cattle and other domestic and wild hosts, is one of the primary limitations of beef cattle farming in some parts of Europe. When an animal tests positive for TB, a loss of profit is caused in the farm, which is due mainly to the animal's slaughter, replacement of the slaughtered animal and the need to immobilize the rest of the herd. We estimated the economic impact in terms of loss of profit as a result of incremental costs and forgone incomes. We show that farms with a larger number of heads are more capable of dealing with the loss of profit caused by the disease. The quantification of the loss of profit contributes to the ongoing debate on the co-sharing of TB costs between government and farmers. The compensation farmers receive from the public administration to mitigate the economic effects of the disease control interventions is only intended to balance the loss due to slaughter of the infected cattle, being the loss of profit a more global concept.

Consideraciones anestésicas en el paciente con enfermedad por virus dengue / Anesthetic considerations in the patient with dengue virus disease

El dengue continúa siendo un problema de salud pública en América. Suele presentarse como una enfermedad febril leve, sin embargo, los pacientes con enfermedad grave pueden presentar síndromes hemorrágicos y choque por dengue. Diferentes circunstancias pueden surgir en el curso evolutivo de los pacientes con dengue impactando en la posibilidad de que sea necesario realizar en ellos una intervención quirúrgica, ante lo cual es necesario plantear las consideraciones anestésicas que deben ser tenidas en cuenta para el correcto abordaje. El presente texto tiene como objetivo establecer consideraciones clínicas útiles para el manejo anestésico en el paciente con enfermedad por dengue para reducir el riesgo de complicaciones peri-operatorias y muerte.

Dengue fever continues to be a public health problem in America. It usually presents as a mild febrile illness, however, patients with severe disease may have hemorrhagic syndromes and dengue shock. Different circumstances can arise in the evolutionary course of patients with dengue impacting on the possibility that it is necessary to perform a surgical intervention, before which it is necessary to raise the anesthetic considerations that must be taken into account for the correct approach. The present text aims to establish useful clinical considerations for anesthetic management in the patient with dengue disease to reduce the risk of peri-operative complications and death.

Experiencia en el uso de tromboprofilaxis farmacológica en un hospital colombiano de tercer nivel / Experience with the use of pharmacological thromboprophylaxis in a tertiary care Colombian hospital

Objetivo: Describir las características de la población con patologías no quirúrgicas en quien se indicó manejo de tromboprofilaxis farmacológica en un hospital de tercer nivel y determinar la indicación según riesgo de tromboembolia venosa (VTE) y sangrado con las escalas Padua e IMPROVE Bleeding Score. Materiales y métodos: estudio observacional, descriptivo, de corte transversal que incluyó a pacientes > 18 años, con patología no quirúrgica del servicio de medicina interna, con estancia hospitalaria mínima de 48 horas, atendidos entre el 1 de junio de 2015 a 1 de junio de 2016. En la valoración de riesgo de VTE y sangrado se aplicaron las escalas Padua e IMPROVE Bleeding Score, respectivamente. Resultados: se incluyeron 531 pacientes, de los que el 51,78% fueron hombres, con una edad promedio de 66 años y hospitalización de 37,2 días. La indicación farmacológica más empleada fue la heparina de bajo peso molecular (76,3%). De acuerdo a la escala de Padua, solo 225 pacientes (42,37%) tenían un alto riesgo de tener VTE; según la IMPROVE Bleeding Score, 447 (84,18%) pacientes presentaban bajo riesgo de sangrado y 84 pacientes (15,81%) alto riesgo. Además, se observó que los pacientes con puntaje PADUA ≥ 4, el 21,33% tenía puntaje IMPROVE Bleeding Score ≥7, adicionalmente el 20,23% de los pacientes con alto riesgo de sangrado según esta última escala presentó un episodio de sangrado. Conclusión: se evidenció un sobreuso de tromboprofilaxis farmacológica, lo cual se ve reflejado en episodios de sangrado en paciente que no tenían indicado su uso

Objective: To describe the characteristics of the population with non-surgical conditions who were prescribed pharmacological thromboprophylaxis in a tertiary care hospital, and to determine the indication according to the risk for developing venous thromboembolism (VTE) and bleeding using the Padua Scale and the IMPROVE Bleeding Score. Materials and Methods: This is an observational, descriptive, and cross-sectional study that included patients >18 years old from the internal medicine ward who had no surgical conditions, who were hospitalized for 48 hours as a minimum, between June 1st, 2015 and June 1st, 2016. When assessing the risk for VTE and bleeding the Padua scale and the IMPROVE Bleeding Score were used, respectively. Results: Five-hundred and thirty-one patients were included, half of them (51.78%) were male, their mean age was 66 years, and their average hospitalization time was 37.2 days. The most frequently used pharmacological indication was low molecular weight heparin (76.3%). According to the Padua scale, only 225 patients (42.37%) were at high risk for developing VTE; according to the IMPROVE Bleeding Score, 447 (84.18%) patients were at low risk for bleeding, and 84 patients (15.81%) were at high risk. Also, it was observed that patients with a >4 score in the PADUA scale, 21.33% had >7 points in the IMPROVE Bleeding Score; additionally, 20.23% of patients at high risk for bleeding according to the latter instrument had a bleeding episode. Conclusion: There was overuse of pharmacological thromboprophylaxis, which was reflected in the occurrence of bleeding episodes in patients who did not qualify for such indication

Hallazgos clínicos, ecocardiográficos y electrocardiográficos en donantes de sangre seropositivos para Trypanosoma cruzi en un centro de referencia del sur de Colombia / Clinical, cardiac ultrasonography, and electrocardiographic findings in blood donors who were found to be seropositive for Trypanosoma cruzi infection in a reference center in southern Colombia

Objetivo: Evaluar las características clínicas y hallazgos electrocardiográficos como de ecocardiografía en pacientes quienes tenían una serología positiva en el banco de sangre de un centro de referencia del sur de Colombia. Material y métodos: Estudio descriptivo, de corte transversal, en el que se analizaron todos los eventos de donación del banco de sangre del Hospital Universitario Hernando Moncaleano Perdomo, de Neiva Huila Colombia, en un periodo comprendido entre enero del 2011 hasta diciembre de 2014. Fueron incluidos pacientes mayores de 18 años, con serología IgG por ELISA positiva para Trypanosoma cruzi, posteriormente confirmada por detección de IgG por inmunofluorecencia indirecta. Se les realizó anamnesis clínica, examen físico, ecocardiogramas transtorácicos y monitoreos electrocardiográficos de ritmo cardiaco 48 durante horas. Resultados: Se registraron 41 865 donantes en el banco de sangre, la prevalencia de infección por T. cruzi fue de 0,15%, promedio de edad 47,8 años, 68,42% de género masculino y la mayoría de zona urbana. Un porcentaje importante de los pacientes manifestó alguna sintomatología relacionada con cardiopátia chagásica. Además la mayoría presentó compromiso de la fracción de inyección del ventrículo izquierdo (leve a moderado) y en la totalidad se detectó alguna anormalidad electrocardiográfica. Conclusión: El hallazgo en el índice de variabilidad de la frecuencia cardíaca se debería considerar como un posible indicador importante en esta patología, en cuanto al reconocimiento temprano antes de notar alteraciones estructurales que generen una falla cardíaca sintomática en esta patología

Objective: This study aimed to assess the clinical characteristics and the electrocardiographic and cardiac ultrasonography findings in patients who had positive serology test results for Chagas' disease in a reference center in southern Colombia. Materials and methods: This is a descriptive, cross-sectional study in which we assessed all blood donating events in the blood bank of the Hernando Moncaleano-Perdomo Hospital in Neiva Huila, Colombia, from January, 2011 to December, 2014. Patients more than 18 years old who had positive results in the serum IgG measurement for Trypanosoma cruzi, which had to be confirmed afterwards using indirect immunofluorescence for IgG detection. The patients had a medical history taken, they underwent physical examination, transthoracic cardiac ultrasonography, and electrocardiographic continuous 48-hour monitoring. Results: Nearly forty-two thousand (41,865) blood donors were recorded in the blood bank. The prevalence of T. cruzi infection was 0.15%, the average age of the subjects was 47.8 years, two thirds (68.42%) were male, and most came from urban areas. An important proportion of patients presented with some symptoms related to Chagas' disease cardiopathy, most had alterations in the left ventricular ejection fraction and all of them showed at least one electrocardiographic abnormality. The finding in the index of heart rate variability should be considered as a possible early indicator in this pathology, before the presence of structural alterations that could generate a symptomatic heart failure

Sarcoma histiocítico: presentación de un caso probable / Histiocytic sarcoma: Presentation of a probable case

El sarcoma histiocítico es un desorden de células no Langerhans extremadamente raro con un curso clínico agresivo y limitadas opciones de tratamiento. Se presenta el caso de un paciente adulto joven de género masculino, con cuadro febril prolongado, compromiso hematológico persistente, hepatoesplenomegalia y linfadenopatias generalizadas con curso clínico fatal, en quien por las características clínicas, paraclínicas y de estudios histopatológicos como de inmunohistoquímica se llegó a dicha presunción diagnostica

Histiocytic sarcoma is an extremely rare non-Langerhans cell disorder with an aggressive clinical course and limited options for therapy. We present the case of a young adult male patient, with prolonged fever, persistent hematological involvement, hepatosplenomegaly, and generalized lymphadenopathy with a fatal clinical course, in whom we arrived to this presumptive diagnosis considering the clinical, paraclinical, and histopathological characteristics, as well as immunohistochemistry

Anemia de Diamond Blackfan: un diagnóstico de exclusión / Anemia of Diamond Blackfan: an exclusión diagnosis

La anemia de Diamond Blackfan es un trastorno genético y clínico raro, caracterizado por aplasia eritrocitaria, que clásicamente se manifiesta durante el primer año de vida, típicamente a los 2-3 meses de edad. El 25% de los afectados presentan anemia severa en la infancia, normo o macrocitosis, reticulocitopenia y disminución selectiva de células precursoras eritroides en medula ósea. Es causada por mutaciones que afectan genes que codifican para proteínas ribosomales, inicialmente fue identificado RPS19, que codifica la proteína S19 y las mutaciones a otros genes que codifican proteínas ribosomales. Se presenta el caso de una paciente de cuatro meses de edad quien debutó con anemia severa, quien no mejoró con la suplencia de hierro, vitamina B12, y ácido fólico y además fueron descartadas sistemáticamente causas frecuentes de anemia. El diagnóstico de anemia de Diamond Blackfan en nuestro medio es un diagnóstico de exclusión, dada la dificultad para acceso a pruebas de confirmación genética. Se establece el diagnóstico y se da manejo con glucocorticoides con buena respuesta clínica y paraclínica

The Diamond Blackfan anemia is a rare genetic and clinical disorder. It is characterized by red cell aplasia, which typically occurs during the first year of life, typically during the second to the third month of age. 25% of the patients had severe anemia during their childhood, normo or macrocytosis, reticulocyte and selective decrease in the number of erythroid precursor cells in bone marrow. It is caused by mutations affect genes encoding ribosomal proteins, RPS19 initially was identified, which encodes S19 protein and mutations in other genes encoding ribosomal proteins. We present a case of a four-month-old who debuted with severe anemia in whom the substitution were iron supplements, vitamin B12 and folic acid, showed no improvement and who also were systematically discarded as common causes of anemia. The diagnosis of Diamond Blackfan anemia in our country is a diagnosis of exclusion, given the difficulty of access to genetic confirmation tests. In this article the diagnosis is established and gives management with glucocorticoid with good clinical and paraclinical response

Objective: To characterize patients with a diagnosis of transverse myelitis (TM) in a referral hospital in southern Colombia during years 2007 to 2013. Material and methods: This is a crosssectional study. All patients with a TM diagnosis were included, according to the criteria set by the Transverse Myelitis Consortium Working Group. Results: We had a total number of 21 cases of TM (1.3 cases/10,000 admissions). Two thirds (66,7%) of all patients were between 15-30 years of age, 57,1% were female; 81.0% had an acute presentation, 100% had motor deficit, 52.4% had autonomic bladder dysfunction, and 81.0% had sensitive level. MT findings were documented using magnetic resonance imaging in 71.4% of cases and 50% by high protein levels in the cerebrospinal fluid. Two thirds (66.7%) of the cases had an unknown etiology. In those cases in which their origin could be identified, the etiologies were: Type I Herpes Simplex (9.5%); Varicella Zoster (9.5%), acute myeloid leukemia (4.8%), systemic lupus erythematosus (4.8%) and vitamin B12 deficiency. Conclusion: MT is a major public health problem, and it is necessary to consider its clinical features, to establish its idiopathic forms and to recognize its infectious causes given their therapy impact and prognosis

Disfunción autonómica debido a accidente escorpiónico: reporte de caso / Autonomic dysfunction caused by scorpion accident: report of a case

El escorpionismo se caracteriza por presentar un espectro clínico variable que puede incluir desde la presencia de dolor urente localizado en el sitio de picadura hasta el compromiso de pares craneales, colapso cardiovascular y muerte. Se presenta el caso de un paciente varón de 17 años de edad, sin antecedentes de importancia, quien sufrió escorpionismo; inicialmente presentó dolor generalizado, fasciculaciones musculares, diaforesis, signos de inflamación en el sitio de picadura. Al examen físico se encontró bradicardia sinusal e hipertensión persistente, exantema maculopapular, prolongación en el tiempo de llenado capilar y edema periorbitario. Los exámenes de laboratorio mostraron leucocitosis neutrofílica. Tanto el compromiso simpático como parasimpático persistieron hasta 96 horas luego del ingreso. Aproximadamente en el 85% de los casos las manifestaciones clínicas son leves; mientras que en el 15% restante pueden haber alteraciones cardiacas, pulmonares, neurológicas -a nivel central y periférico- que provoquen una disfunción autonómica, e incluso llegar a la muerte. La familia Buthidae es la principal implicada en este tipo de accidentes

Scorpionism is a public health problem, characterized by a variable clinical spectrum of clinical manifestations like a pain at the sting site, cranial nerves involvement, cardiovascular collapse and death. The following case presents a man without medical history important, who suffers the sting of a scorpion, initiates the symptoms consisting of generalized pain, muscular fasciculations, diaphoresis, signs of inflammation at the sting site. On physical examination presents sinus bradycardia and persistent hypertension, exanthema maculopapular, prolongation in capillary filling time and periorbital edema, in laboratory tests evidence neutrophilic leukocytosis. Approximately 85% of the clinical manifestations of scorpionism are mild but it is estimated that the remaining 15% can generate cardiac and pulmonary manifestations, and central and peripheral nervous system involvement, generating autonomic dysfunction that can evolve to a fatal outcome, being its main family Buthidae
