Necrolisis tóxica epidérmica en cuidados intensivos / Epidermal toxic necrolysis in intensive care

Se estudiaron dos pacientes ingresados en sala de cuidados intensivos polivalente, los cuales presentaron necrolisis tóxica epidémica (NTE), complicación poco frecuente que tiene una incidencia de 1 a 4 casos por millón de habitantes. La causa de la enfermedad en estos pacientes fue medicamentosa y los principales medicamentos implicados fueron anfotericin B y ciprofloxacino. Una de las cuestiones que hace interesante el reporte de estas reacciones adversas es que se trata del primer caso de NTE relacionada con el uso de Anfotericin B Liposomal que se reporta en Cuba y en el resto de la comunidad científica. El diagnóstico se confirmó por biopsia de piel, ambos pacientes presentaron un riesgo de muerte, según índice de Scorten, mayor al 50 por ciento. Por lo infrecuente que es el tratamiento de esta afección en una sala de cuidados intensivos polivalentes, por lo raro que es ver esta enfermedad en relación a estos antibióticos antes mencionados, por lo dramático del cuadro clínico y por la evolución tórpida de los pacientes, se realizó esta investigación con el objetivo de transmitir la experiencia y el conocimiento a la comunidad médica y científica en general y a los profesionales que laboran en las salas de terapia intensiva polivalente en particular(AU)

Two patients admitted to a multipurpose intensive care ward were studied. They showed epidemic toxic necrolysis (NTE), a rare complication that has an incidence of 1 to 4 cases per million inhabitants. Drugs were the cause of the disease in these patients and the main drugs involved were amphotericin B and ciprofloxacin. This is the first case of NTE related to the use of Liposomal Amphotericin B reported in Cuba and in the rest of the scientific community, which makes it interesting. The diagnosis was confirmed by skin biopsy, both patients had risk of death, according to the Scorten index, higher than 50 percent. This research was carried out with the aim of communicating the experience and knowledge to the medical and scientific community in general and to the professionals who work in multipurpose intensive care rooms in particular, since this condition is rare in a multipurpose intensive care room, it is rare in relation to the aforementioned antibiotics, its dramatic clinical status and the torpid evolution of patients(AU)

Demografia, óbitos e indicadores de agravamento nas internações por intoxicações medicamentosas entre menores de 5 anos no Brasil / Demographics, deaths and severity indicators in hospitalizations due to drug poisoning among children under age five in Brazil

RESUMO: Introdução: No Brasil, os medicamentos são os principais agentes causadores de intoxicação, e o maior número de casos desse problema envolve menores de 5 anos. Assim, o objetivo deste estudo foi descrever as internações por intoxicação medicamentosa nessa população quanto a sua demografia, óbitos e indicadores de agravamento. Métodos: Verificou-se a frequência das internações por intoxicação medicamentosa entre 2003 e 2012, utilizando os dados do Sistema de Informação Hospitalar. As variáveis utilizadas foram ano, sexo, idade, município de residência e de internação, evolução do paciente, diagnóstico principal, diagnóstico secundário, natureza do estabelecimento de saúde e valor referente aos gastos de unidade de terapia intensiva. Resultados: Ocorreram 17.725 internações por intoxicação medicamentosa em menores de 5 anos de idade, com o predomínio do sexo masculino e de crianças de 2 anos. As internações fora do município de residência deram-se em 25% dos casos, com predomínio da Região Nordeste. A proporção de óbitos nas internações foi de 0,4%, com maior número de óbitos na Região Sudeste. Conclusão: Apesar da diminuição do número de internações no período, permaneceram disparidades regionais que podem ser atenuadas com a oferta de atenção especializada às intoxicações medicamentosas nos municípios, ampliando o acesso a cuidados de maior complexidade.

ABSTRACT: Introduction: In Brazil, drugs are the main causative agents of poisonings, and children under age five are the group with the highest number of cases. The objective of the present study was to describe hospitalizations due to drug poisoning in this population regarding demographics, deaths and worsening indicators in hospitalizations. Methods: The frequency of hospitalizations for drug poisoning between 2003 and 2012 was verified using data from the Hospital Information System. The study variables were year, gender, age, place of residence and hospitalization, patient follow-up, main diagnosis, secondary diagnosis, nature of the health establishment and amount related to Intensive Care Unit expenses. Results: There were 17,725 hospitalizations due to drug poisoning in children under five, predominantly two-year-old male children. The hospitalizations outside the city of residence occurred in 25% of the cases, with predominance in the Northeastern region. The proportion of deaths in hospitalizations was 0.4%, with a higher number of deaths in the Southeastern region. Conclusion: Despite the decrease in the number of hospitalizations in the period, regional disparities remained, which could be attenuated with the provision of specialized attention to drug poisonings in municipalities, expanding the access to a more complex care.

Mortalidade e internações hospitalares por intoxicações e reações adversas a medicamentos no Brasil: análise de 2000 a 2014 / Hospitalizations and deaths from drug poisoning and adverse reactions in Brazil: an analysis from 2000 to 2014 / Mortalidad e internamientos hospitalarios por intoxicaciones y reacciones adversas a medicamentos en Brasil: análisis de 2000 a 2014

Resumo: Nos últimos anos, as intoxicações e reações adversas a medicamentos tornaram-se importante causa de hospitalização e mortalidade, constituindo tema de grande relevância para a saúde pública. O objetivo deste estudo foi descrever a tendência de mortalidade e hospitalizações por esses agravos no Brasil, entre os anos de 2000 e 2014. Os dados utilizados foram provenientes dos sistemas SIM (Sistema de Informções sobre Mortalidade) e SIH-SUS (Sistema de Informações Hospitalares do SUS), e a população foi analisada segundo sexo, região de residência e faixa etária. Para definição dos eventos, foram utilizados códigos CID-10. A análise de tendência da série histórica foi realizada por regressão linear generalizada pelo método de Prais-Winsten, com correção do efeito de autocorrelação de primeira ordem. Tanto os óbitos quanto as hospitalizações ocorridas durante o período estudado apresentaram tendência ascendente. Na análise por regiões, as tendências mantiveram-se ascendentes para ambos os eventos nas regiões Sudeste e Sul. A análise por faixa etária mostrou tendências declinantes para menores de cinco anos nos dois eventos, tendência de óbitos ascendente para maiores de quatro anos e tendência de hospitalizações ascendente para a faixa de 20 a 59 anos. As intoxicações e reações adversas a medicamentos apresentam considerável contribuição para a ocorrência de óbitos e hospitalizações no Brasil, e os sistemas de informação SIM e SIH-SUS são fontes de dados de qualidade satisfatória para estudos de base populacional sobre mortalidade e morbidade hospitalar no país.

Abstract: In recent years, drug poisoning and adverse reactions have been an important cause of hospitalization and mortality and a major public health issue. The aim of this study was to describe trends in hospitalizations and deaths from drug poisoning and adverse reactions from 2000 to 2014. Data were from the Mortality Information System (SIM) and Information System on Authorizations for Hospital Admissions of the Brazilian Unified National Health System (SIH-SUS), and the study population was analyzed by sex, region of residence, and age bracket. Events were defined according to ICD-10 codes. The analysis of trends in the historical series used Prais-Winsten generalized linear regression with correction for first order autocorrelation effect. Both the hospitalizations and deaths during the study period showed upward trends. The analysis by regions maintained the upward trends for both events in the South and Southeast regions. Analysis according to age brackets showed downward trends in children under five years in both events, upward trend in deaths in individuals over four years of age, and an upward trend in hospitalizations in the age bracket from 20 to 59 years. Drug poisoning and adverse reactions contribute significantly to hospitalizations and deaths in Brazil, and the SIM and SIH-SUS are data sources with satisfactory quality for population-based studies on hospital morbidity and mortality in the country.

Resumen: Durante los últimos años, las intoxicaciones y reacciones adversas a medicamentos se han convertido en una importante causa de hospitalización y mortalidad, constituyendo un tema de gran relevancia para la salud pública. El objetivo de este estudio fue describir la tendencia de mortalidad y hospitalizaciones por estos riesgos sanitarios en Brasil, entre los años 2000 y 2014. Los datos utilizados provinieron de los sistemas SIM (Sistema de Infomaciones sobre Mortalidad) y SIH-SUS (Sistema de Informaciones Hospilatarias del Sistema Único de Salud), y la población se analizó según sexo, región de residencia y franja de edad. Para la definición de los eventos, se utilizaron códigos CID-10. El análisis de tendencia de la serie histórica se realizó por regresión lineal generalizada, mediante el método de Prais-Winsten, con corrección del efecto de autocorrelación de primer orden. Tanto los óbitos como las hospitalizaciones ocurridas durante el período estudiado presentaron una tendencia ascendente. En el análisis por regiones, las tendencias se mantuvieron ascendentes para ambos eventos en las regiones Sudeste y Sur. El análisis por franja de edad mostró tendencias declinantes para menores de cinco años en los dos eventos, tendencia de óbitos ascendente para mayores de cuatro años y tendencia de hospitalizaciones ascendente para la franja de 20 a 59 años. Las intoxicaciones y reacciones adversas a medicamentos presentan una considerable contribución a la ocurrencia de óbitos y hospitalizaciones en Brasil, y los sistemas de información SIM y SIH-SUS son fuentes de datos de calidad satisfactoria para estudios de base poblacional sobre mortalidad y morbilidad hospitalaria en el país.

Pancreatitis inducida por drogas / DRUG-INDUCED ACUTE PANCREATITIS

Introducción. Las Reacciones Adversas Medicamentosas (RAM) son una de las principales causas de hospitalización y mortalidad en el sistema de salud (en países desarrollados y en vías de desarrollo), y la relevancia va creciendo año tras año. El objetivo de este estudio fue determinar la incidencia de pancreatitis aguda inducida por drogas y los grupos de drogas que más frecuentemente se ven involucrados. Material y Métodos: Se realizó un estudio retrospectivo tomando como fuente una base de datos de farmacovigilancia del Hospital General de Agudos ¨Dr. Cosme Argerich¨ con información de los últimos cinco años. Resultados: Se detectaron siete casos de pancreatitis inducida por drogas de los cuales fueron dos por quimioterápicos (lapatinib e imatinib), tres por antirretrovirales, uno por inmunosupresores y uno por antihipertensivos (enalapril). En cinco casos fue necesaria la hospitalización y un evento fue mortal. Conclusión: De acuerdo a la bibliografía internacional, a pesar de que los fármacos son solo responsables del 1-2% de casos de pancreatitis aguda inducida por drogas, es importante destacar que es difícil encontrar la causalidad entre el fármaco y el cuadro del paciente, lo que lleva muchas veces a un subdiagnóstico como una pancreatitis idiopática. En el presente estudio, estos casos deben considerarse por su impacto, no solo a nivel de la salud del paciente

Adverse Drug Reactions (ADR) are nowadays an increasing problem in health systems and represents between the 4th and the 6th cause of death in developing countries. Drug induced pancreatitis in a rare ADR but reports are increasing with antiretroviral drugs and new antiviral and anticancer drugs. The aim of this study was to determine the incidence of drug ­ induced pancreatitis in a tertiary care hospital. We used a pharmacovigilance database applying de Naranjo Score for drug causality in adverse medical events. From a total of 2990 ADR we detected 7 cases of pancreatitis. Antiretroviral and anticancer drugs were the drugs most frequently involved.

Muerte inducida por medicamentos / FATAL ADVERSE DRUG REACTIONS

Introducción. Las Reacciones Adversas Medicamentosas (RAM) son una problemática subvalorada en la actualidad y con el incremento de hospitalizaciones por RAM también se esta percibiendo en el mundo un aumento de la incidencia de eventos fatales de RAM. Esto genera un replanteo sobre el uso racional de medicamentos y los costos que traen aparejados los medicamentos para los sistemas de salud. Material y métodos. Se realizó un estudio retrospectivo sobre una base de farmacovigilancia del Hospital General de Agudos Dr. Cosme Argerich con datos de cinco años. Se utilizó el score de Naranjo (tabla 1) para determinar la causalidad de una droga en un evento médico adverso. Fueron incluidos en el trabajo aquellos que fueron determinados como ¨ciertos¨ o ¨probables¨. Resultados. En el perído que involucra la base de farmacovigilancia se detectaron 18 eventos de muertes inducidas por medicamentos. Quimioterápicos, inmunosupresores, corticoides y AINEs fueron las drogas más frecuentemente involucradas. Hemorragia digestiva alta e infecciones las patologías que llevaron a la muerte más frecuentemente. Conclusión. Los grupos de drogas involucrados coinciden con los de la bibliografía internacional. Es preciso contar con sistemas de farmacovigilancia estables y sostenidos para poder determinar y cuantificar con más precisión esta problemática creciente

Adverse Drug Reactions (ADR) are one of the most common cause of death in developed countries and in developing countries too. New drugs and aging of the population are two of the mail causes of this. Approximately half of ADR are preventable. The aim of this Word was to determine the incidence of ADR ­ related death in a tertiary care hospital from Buenos Aires. A pharmacovigilance database was used and we applied the Naranjo Score to determine drug causality in adverse medical events. From a total of 2990 ADR, we detected 18 drug related ­ death. Anticancer, steroids and NSAIDs were the drugs most frequently involved

Notificaciones espontáneas de sospechas de reacciones adversas a los medicamentos. Instituto Pedro Kourí / Spontaneous reporting of suspected drug adverse reactions in "Pedro Kouri" Institute of Tropical Medicine

Introducción: las reacciones adversas a los medicamentos se relacionan con la seguridad de los productos farmacéuticos. Están asociadas con altas tasas de morbilidad y mortalidad y alta carga económica para la sociedad. En el Instituto Pedro Kourí las notificaciones de reacciones adversas son inestables y no cuentan con un análisis general de los reportes. Objetivo: caracterizar las reacciones adversas a los medicamentos notificadas en el Instituto Pedro Kourí durante el periodo 2011 a 2013. Método: estudio de farmacovigilancia, observacional, descriptivo y transversal, a partir de todos los reportes de reacciones adversas notificados por los profesionales del Instituto durante el período de tiempo seleccionado. Se clasificaron según la imputabilidad, la frecuencia y el tipo de reacción. Fueron identificados los fármacos sospechosos y se estudiaron los pacientes que las manifestaron. Resultados: se reportaron 77 reacciones adversas, relacionadas todas con medicamentos antinfecciosos, de ellos los antirretrovirales con el 75,3 por ciento fue el grupo farmacológico que más se asoció con la producción de las mismas. La mayoría de los reportes se corresponden con pacientes masculinos (80,5 por ciento) y jóvenes (51,9 por ciento). Clasificaron como probables el 66,0 por ciento y definitivas el 6,4 por ciento. Conclusiones: todas las reacciones adversas a los medicamentos reportadas en el Instituto durante el trienio 2011-2013 se presentaron en pacientes con VIH/SIDA y se destacó la severidad de las mismas(AU)

Introduction: Adverse drug reactions are related to safety of pharmaceuticals, to high morbidity and mortality rates and to high economic burden upon the society. In Pedro Kouri Institute of Tropical Medicine, the adverse drug reaction notifications are inconsistent and there is no general analysis of reports. Objectives: To characterize the adverse drug reactions reported in Pedro Kouri Institute in the period of 2011 through 2013. Method: Observational, descriptive and cross-sectional pharmacovigilance study based on all the reports on adverse drug reactions by the professionals of the Institute during the selected period of time. They were classified according to attributable cause, frequency and type of reaction. Suspected drugs were identified and the patients who manifested these reactions were also studied. Results: Seventy seven adverse reactions were reported and all of them were related to anti-infection drugs; antiretrovirals accounted for 75.3 percent and was the drug group mostly associated to them. The majority of reports were made on males (80,5 percent) and young people (51,9 percent). They were classified as probable in 66 percent of cases and definitive in 6,4 percent. Conclusions: All the adverse drug reactions reported in the Institute in the 2011 to 2013 period were observed in HIV/aids patients and were severe ones(AU)

Reacciones adversas medicamentosas y errores de prescripción: morbi-mortalidad / Adverse drug reactions and prescription errors: morbi-mortality

La farmacovigilancia tiene por objeto la detección, evaluación, comprensión y prevención de cualquier problema relacionado a las drogas. La recolección de información relacionada a reacciones adversas medicamentosas (RAM) posterior a la aprobación y el manejo del riesgo basados en los datos observacionales son críticos para la salud pública.El objetivo primario fue evaluar la morbimortalidad de las reacciones adversas medicamentosas y describir los errores médicos de prescripción en un hospital público de la Ciudad de Buenos Aires. Se llevó a cabo un estudio prospectivo observacional. Se definió RAM como cualquier manifestación nociva, clínica y/o biológica imputable a un medicamento, que ocurra a las dosis habitualmente utilizadas en humanos para la profilaxis, diagnóstico o tratamiento de una enfermedad. La mortalidad global fue del 7% (21/310) y la atribuible a RAM observada fue del 1% (3/310). Se identificaron 149 RAMs en el 36% de los pacientes (111/310) y las RAM constituyeron el 11% (35/310) de los motivos de internación. Las RAM causan un número significativo de internaciones y son responsables de morbilidad evitable durante la internación. Ningún fármaco aislado causó más del 6% de las RAM, por lo que las estrategias para disminuirlas deben estar dirigidas a múltiples grupos farmacológicos.

Pharmacovigilance aims to detect, assess, understand and prevent any possible drug-related problem. The record of information related to adverse drug reactions (ADRs) after drug approval and risk management based on observational data are crucial for public health. The main goal was to assess the ADRs morbimortality and to describe prescription medical errors in a public hospital in the city of Buenos Aires. A prospective observational study was undertaken. ADR was defined as any clinical and/or biological noxious manifestation imputable to a drug, which occurs at the usually used dose in humans for disease prophylaxis, diagnosis or treatment. Global mortality was 7% (21/310). The observed mortality due to ADR accounted for 1% (3/310). One hundred and forty nine ADRs in 36% of patients were identified (111/310), and 11% (35/310) of the hospital admissions were due to ADRs. ADRs cause a great number of admissions and are responsible for preventable morbidity during hospitalization. Neither drug alone caused more than 6% of the ADRs. For this reason, in order to diminish ADRs, strategies should be addressed to multiple drug groups.

Relevancia de la farmacovigilancia hospitalaria en la práctica médica actual / Importance of pharmacovigilance in current medical practice

Las reacciones adversas medicamentosas (RAM) generan actualmente una notable morbimortalidad, llegando a representar entre la cuarta y sexta causa de muerte y hasta un 12% de las hospitalizaciones en países desarrollados. Este es, además, un problema creciente. El objetivo del trabajo fue revisar la incidencia de RAM en un hospital de alta complejidad. Se revisó la base de datos del sistema de farmacovigilancia, desde junio de 2008 hasta febrero de 2012. Para determinar la causabilidad de una droga en un evento médico se aplicó el índice de Naranjo de efectos indeseables medicamentosos. Se consideró RAM grave a aquella que provoca la internación, la prolonga, compromete seriamente la vida, genera discapacidad permanente o teratogénesis o induce la muerte. Se detectaron 2420 RAM en este período. 469 (19.38%; IC 95%: 17.80-20.95) fueron serias, principalmente debido a que fueron causa de hospitalización (n = 287). Hubo 14 muertes atribuibles a RAM. Los grupos farmacológicos más frecuentemente asociados a toxicidad fueron drogas cardiovasculares, antibióticos, neuropsiquiátricas y corticoides. Las RAM más frecuentes afectaron al sistema endocrinometabólico, causaron hepatotoxicidad, nefrotoxicidad y farmacodermias. Las causas más frecuentes de hospitalización por RAM fueron infecciones graves asociadas a tratamiento inmunosupresor y hemorragia digestiva por anticoagulación y antiinflamatorios no esteroides. La incidencia de RAM en pacientes hospitalizados y el número de hospitalizaciones por este motivo fue elevado. Las drogas involucradas fueron similares a las comunicadas en la bibliografía internacional, salvo la alta incidencia de RAM relacionadas a inmunosupresores.

Adverse drug reactions (ADRs) are cause of significant morbi-mortality They are between the fourth and sixth cause of mortality in developed countries and cause nearly 12% of hospitalizations. The objective of this publication was to analyze the incidence of ADRs in a tertiary care hospital in Buenos Aires City. The hospital phamacovigilance database for the period June 2008- February 2012, was analyzed. The Naranjo score was applied to assess drug causality. We consider serious an ADRs when it potentially compromised life, induced hospitalization or prolonged it, caused discapacity, teratogenesis or death. In this period, a total of 2420 ADRs were detected: 469 (19.38%; CI 95%: 17.80 - 20.95) were serious, mainly because they induced hospitalization (n = 287). There were 14 ADRs-related deaths. Cardiovascular and neuropsychiatric drugs, antibiotics and corticoids were those most frequently related to toxicity. Endocrine-metabolic disorders, hepatotoxicity, nephrotoxicity and pharmacodermy were the most frequently involved. Among the ADR most frequently associated to hospitalization were Immunosuppressant-associated severe infections and upper gastrointestinal bleeding related to oral anticoagulants and non steroids anti-inflammatory drugs. The ADRs incidence in hospitalized patients and ADRs related hospital admissions were considered relatively high. Drugs involved were similar to those reported in the international bibliography except for the higher incidence of immunosuppressants related admissions here observed.

Attitude and practice of doctors toward adverse drug reactions (adrs) reporting in a Nigerian tertiary health facility

Background : Adverse drug reactions; (ADRs); constitute an important cause of morbidity and mortality worldwide. Spontaneous adverse drug reaction (ADR) reporting is the bedrock of post-marketing surveillance but under-reporting remains its major drawback. Objectives : This study aimed at evaluating the attitude and practice of ADR among doctors in a tertiary health facility in Oyo State; Nigeria; with a view to improving ADRs reporting. Methods : This was a cross-sectional questionnaire based study involving medical doctors working at the Ladoke Akintola University of Technology (LAUTECH) Teaching Hospital; Ogbomoso. Consenting doctors were evaluated on their attitude and practice of ADRs through self-administered questionnaire. Data obtained were entered and analyzed using SPSS version 17. Results : A total of 35 doctors responded to the questionnaires. Only about 57.1 considered ADR before prescribing; all of whom were also aware of the procedure for reporting. Awareness of the existence of National Pharmacovigilance Center (NPC) was 71.4. Thirty (85.7) of the respondents have encountered ADR; but only 2.9 have ever reported it with yellow form. Majority (85.7) of the respondents did not consider ADR reporting as a useful tool in the prevention of drug related morbidities and mortalities. Other factors that may hinder ADR reporting include: lack of awareness of the existence of yellow forms for reporting (68.6) and poor knowledge of procedure for reporting (48.6). Conclusion : ADR reporting rate was very low among the participants in this small study; large studies aimed at evaluating the determinants of ADR reporting should be considered. Should these findings be confirmed; training and re-retraining through Continuing Medical Education (CME); and establishment of pharmacovigilance committee would be required to ensure a national pharmaovigilance system

Immune activation; allergic drug toxicity and mortality in HIV-positive tuberculosis

This study was conducted to correlate serum levels of markers of immune activation with mortality and drug toxicity in HIV+TB. Design: Substudy of a randomised clinical trial of streptomycin-thiacetazone-isoniazid (STH) vs. rifampin-isiniazid-pyrazinamide (RHZ) in HIV + TB. Design: Substudy of a randomized clinical trial of streptomycin-thiacetazone-isoniazid (STH) vs. rifampin-isoniazid-pyrazinamide (RHZ) in HIV + TB. Results: Neopterinor =14 ng/mg; TNF-alpha receptorsor = 6.5 ng/ml; and negative skin test were independently associated with increased mortality (P0.01). Among STH-treated subjects; dermatologic toxicity and mortality (P0.05); although these two adverse events occurred independently. Activation markers increased from baseline after 2 months of therapy with the less rapidly bactericidal STH regimen; whereas they declined in those treated with RHZ; suggesting a relationship with continued mycobacterial replication. Conclusions: Immune activation in HIV+TB is associated with shortened survival and increased risk of drug toxicity. HIV+TB patients with elevated serum neopterin should be treated with a rapidly-bactericidal drug regimen which does not include thiacetazone

Síndrome febril prolongado en drogadicto coincidiendo con depósitos de cristales de basuco / Prolonged fever syndrome in a drug addict: effects and complications of bazooko

El auge de la Drogadicción en las últimas décadas, ademas de evidenciar una intensa problemática social, ha dado lugar a la aparición de una serie de nuevas patologías, las cuales requieren constante investigación. Presentamos en este trabajo la historia clínica de un paciente adicto al Basuco (pasta de coca) en quien se estudio la aparición de granulomas a cuerpo extraño, en tejido linfático cervical. Estos granulomas, han sido aislados en otros tejidos como Celular Subcutáneo, Hígado, Médula Osea, Bazo y Gánglios Linfáticos de diversa localización. Al ser estudiados con luz polarizada, se hallaron cristales birrefringentes en su parte central. Dichos cristales serían resultados del depósito de restos de Hidróxido de Magnesio, contenido en la cocaína no refinada, procesada con diversas sustancias para el logro de la pasta de coca (Basuco o Crack). Para producir granulomas una partícula debe medir entre 1 y 100 Nm en su forma colonial, tomando la transformación de silicato, varios años. Otro aspecto de interés en el caso presentado, lo constituye la coexistencia de Mielofibrosos con la ya mencionada; demostrado una vez más la afectación sistemica producida porla droga. Pensamos que para el Internista de hoy, así como para el médico de otras especialidades, reviste gran interés la descripción de cuadros de este tipo, el cual puede servir de punto de partida para investigaciones ulteriores, en la lucha contra este gran flagelo de la sociedad
