Perfil clínico y abuso de metanfetamina no recreativa (shabú) entre los pacientes con ictus en la población filipina / Clinical profile and non-recreational methamphetamine abuse (shabu) among stroke patients in the Philippine population

Introducción En la población filipina de Barcelona está aumentando el consumo crónico no recreativo de metanfetaminas (shabú). La población asiática presenta un patrón de ictus diferente, con mayor incidencia de hemorragias, y diferentes factores de riesgo vascular y conductas de salud. El objetivo es describir el perfil de ictus e incidencia de consumo de metanfetaminas en pacientes de origen filipino ingresados en nuestro centro. Pacientes y métodos Se registraron datos demográficos, factores de riesgo vascular, datos clínicos y pronóstico. Se analizó la exposición a metanfetamina en muestras de plasma recogidas en el ingreso, que se analizaron por cromatografía líquida-espectrometría de masas. Resultados Del total de 6.418 pacientes con ictus, se identificó a 73 pacientes filipinos (1,1%). La edad media era de 54,4 ± 12,1 años, el 54% eran hombres y el ictus era isquémico en el 64,4%. La hipertensión arterial fue el principal factor de riesgo. Diez (13,7%) pacientes dieron positivo a metanfetamina y anfetamina. Estos resultados confirman un consumo reciente de sustancias previo al ictus, principalmente en hombres (80%). En pacientes consumidores, un 60% presentaba un ictus hemorrágico, con mal pronóstico funcional a tres meses en el 55,6% de los pacientes. Conclusiones En nuestro medio, los pacientes de etnia filipina ingresados por ictus en relación con consumo de shabú presentaron un perfil de edad más joven, con menor prevalencia de factores de riesgo vascular y predominio del subtipo hemorrágico. Se recomienda la determinación de metanfetamina en los pacientes filipinos con ictus debido a la alta prevalencia del consumo de metanfetamina en nuestro país. (AU)

INTRODUCTION Chronic non-recreational use of methamphetamine (shabú) is increasing among the Filipino population in Barcelona. The Asian population presents a different stroke pattern, with a higher incidence of haemorrhage, and different vascular risk factors and health behaviours. The objective of this study is to describe the stroke profile and incidence of methamphetamine use in patients of Filipino origin admitted to our centre. PATIENTS AND METHODS Demographic data, vascular risk factors, clinical data and prognosis were recorded. Methamphetamine exposure was analysed in plasma samples collected on admission, which were then analysed by liquid chromatography-mass spectrometry. RESULTS Of a total of 6,418 stroke patients, 73 (1.1%) were identified as being of Filipino origin. The mean age was 54.4 ± 12.1 years, 54% were male and the stroke was ischaemic in 64.4% of cases. Arterial hypertension was the main risk factor. Ten (13.7%) patients tested positive for methamphetamine and amphetamine. These results confirm recent substance use prior to the stroke, mostly in men (80%). In patients who were consumers, 60% had a haemorrhagic stroke, with a poor functional prognosis at three months in 55.6% of patients. CONCLUSIONS In our setting, patients of Filipino ethnicity admitted for stroke related to the consumption of shabú belonged a younger age bracket, with a lower prevalence of vascular risk factors and a predominance of the haemorrhagic subtype. Methamphetamine testing in Filipino stroke patients is recommended due to the high prevalence of methamphetamine use in our country. (AU)

Consumo de drogas: enfrentamiento a un problema latente / Drug use: confronting a latent problem i: en

Algunas situaciones ponen en riesgo a Cuba en cuanto al uso de drogas, entre ellas el aumento del turismo, las relaciones con países que poseen altas tasas de consumo, la ubicación geográfica en corredores de narcotraficantes y la alta prevalencia de drogas porteras. Al respecto, el Sistema Nacional de Salud debe estar preparado para la prevención del problema y la atención a los afectados, de manera que resulta necesario mantener una información actualizada sobre los factores de riesgo y los principales productos utilizados por los consumidores. En la presente revisión bibliográfica sobre el tema se busca llamar la atención de los trabajadores de la salud en tal sentido, se ofrecen datos sobre la magnitud del problema y se abordan elementos de sus antecedentes, así como de la clasificación de las drogas, los factores de riesgo asociados a su consumo y las bases jurídicas para su control en Cuba.

Some situations put Cuba at risk for drug use, such as an increase in tourism, relations with countries that have high rates of substance abuse, the geographic location in drug trafficking corridors, and the high prevalence of "opening doors" drugs. In this regard, the National Health System must be prepared to prevent the problem and care for those affected, so it is necessary to maintain updated information on risk factors and main products used by consumers. In the present literature review on the subject, it is sought to draw the attention of health workers to this point, data on the magnitude of the problem and elements of its background are offered, as well as drug classification, the risk factors associated with its use and the legal bases for its control in Cuba.

El Chemsex desde los Servicios de Análisis de Sustancias: estudio descriptivo sobre la metanfetamina, mefedrona yotras catinonas sintéticas / Chemsex from Drug Checking Services: Descriptive Study on Methamphetamine, Mephedrone, and Other Synthetic Cathinones

Antecedentes: Los Servicios de Análisis de Sustancias (SAS) han demostrado ser una intervención eficazque permite acceder a población a prácticas de consumo más seguras. Este estudio se centra en la poblaciónusuaria de Chemsex. Material y métodos. Análisis descriptivo de las muestras de sustancias cedidas porpersonas participantes en prácticas de Chemsex, enfocándose en metanfetamina (MET), mefedronay otras catinonas sintéticas. Los datos fueron recopilados por el Servicio de Información, Análisis deSustancias y Asesoramiento sobre Sexualidades (SIASAS) de Chem-Safe (Energy Control). Se examinaronlas características sociodemográficas de las personas usuarias, los contextos de adquisición de las sustanciasy su composición química. Resultados. La población de personas usuarias del SIASAS de Chem-Safe queparticipan en sesiones de Chemsex está compuesta principalmente por hombres de mediana edad. Sehan analizado 15 tipologías de sustancias diferentes con predominancia de MET y catinonas. En la primerade ellas está presente la adulteración por adición únicamente y un predominio de la vía fumada (50%),mientras que en el caso de las catinonas sintéticas se identifica un elevado índice de adulteración porsustitución y un predominio de la vía endovenosa y esnifada (41,67% respectivamente). Conclusiones. Lasprincipales sustancias analizadas desde el SIASAS son la MET y las catinonas sintéticas. Entre ambas existendiferencias tanto en su modo de obtención, como contexto de adquisición, administración y adulteración,lo que comporta un aumento de los riesgos para la salud de las personas usuarias.

Background: Drug Checking Services (DCS) have proven to be an effective intervention thatallows access to safer consumption practices for the population. This study focuses on the userpopulation engaged in Chemsex practices. Materials and Methods. A descriptive analysis of substance samples provided by individuals participating in Chemsex practices, with a focus on methamphetamine (METH), mephedrone, and other synthetic cathinones. Data were collected bythe Drug Checking and Sexuality Counseling Service (DCSCS) of Chem-Safe (Energy Control).Sociodemographic characteristics of users, substance acquisition contexts, and chemical composition were examined. Results. The Chem-Safe DCSCS user population engaging in Chemsex sessions consists predominantly of middle-aged men. Fifteen different substance typologieswere analyzed, with METH and cathinones predominating. In the case of METH, adulterationthrough addition was found, with a predominance of the smoked route (50%). Synthetic cathinones showed a high rate of adulteration through substitution, with a preference for intravenousand insufflation routes (41.67% each). Conclusions. The main substances analyzed by DCSCS areMETH and synthetic cathinones, revealing differences in acquisition, administration, and adulteration contexts. This contributes to an increased health risk for users. (AU)

Detection of unsuspected cathinone and piperazine-type drugs in urine samples positive for methamphetamine and amphetamine collected in emergency departments. / Detección no sospechada de catinonas y piperacinas en pacientes consumidores de metanfetamina y anfetamina atendidos en servicios de urgencias hospitalarios.

OBJECTIVES: To detect the presence of unsuspected and/or undeclared cathinone and piperazine-type designer drugs in methamphetamine (METH) and amphetamine users treated in emergency departments, and to compare clinical and toxicologic profiles. MATERIAL AND METHODS: Retrospective observational study of emergency department patients treated for confirmed acute intoxication by recreational drugs (METH and amphetamines) between March 2019 and December 2020. We ordered high-performance liquid chromatography with tandem mass spectrometry to detect cathinones (methylone, fluoromethcathinone, mexedrone, fluoromethamphetamine, mephedrone, methylenedioxypyrovalerone) and synthetic piperazines (meta-chlorophenylpiperazine and trifluoromethylphenylpiperazine). Demographic, clinical, and toxicologic variables were analyzed with SPSS software (version 23). RESULTS: Thirty-nine patients were included: 24 (61.5%) had used METH and 15 (38.5%) an amphetamine. Synthetic cathinones were detected in samples from 11 patients (28.2%), 10 (90.9%) in the METH group and 1 (9.1%) in the amphetamine group (P = .028). The METH users had taken mephedrone (8 patients) or methylone (2 patients); the amphetamine user had taken mephedrone. None of the patients had declared use of a cathinone; nor was use suspected. The mean (SD) number of substances involved was higher among users of cathinones (3.5 [1.13] vs 2.5 [1.40] in those who took no cathinones; P = .036). Among the cathinone users, 90.9% were men, 90.9% had used METH, and 45.5% had practiced chemsex. HIV positivity was significantly associated with cathinone use (in 45.5% vs 10.7% of those not using cathinones; P = .028). All 5 of the patients who had taken cathinones and also practiced chemsex were HIV positive. Significantly more patients who had taken cathinones presented with anxiety (72.7% vs 21.43%; P = .007). No differences in clinical management were found. CONCLUSION: Detection of METH in intoxicated patients should raise suspicion of probable use of a synthetic cathinone. Patients in whom new psychoactive substances are detected should be kept under observation, and clinical protocols should include referring them to addiction treatment centers.

OBJETIVO: Determinar la incidencia de catinonas y piperazinas, no sospechadas y/o declaradas en consumidores de metanfetamina (MANF) y anfetamina (ANF) atendidos en servicios de urgencias hospitalarios (SUH) y comparar los perfiles clínicos y toxicológicos. METODO: Estudio retrospectivo de pacientes con intoxicación aguda por drogas recreativas con MANF y ANF confirmadas analíticamente atendidos en 3 SUH entre marzo de 2019 y diciembre de 2020. Se detectaron por HPLC-MS/MS las catinonas [metilona, fluorometcatinona, mecedrona, fluorometanfetamina, mefedrona, metilendioxipirovalerona (MDPV)] y las piperazinas sintéticas [meta-clorofenilpiperazina (mCPP), trifluorometilfenilpiperazina (TFMPP)]. RESULTADOS: Se incluyeron 39 pacientes: 24 (61,5%) en el grupo MANF y 15 (38,5%) en el ANF. En 11 (28,2%), se detectaron catinonas sintéticas (grupo CAT), 10 en el grupo MANF (8 mefedrona, 2 metilona) y 1 en el grupo ANF (1 mefedrona) (90,9% vs 9,1%; p = 0,028). Ninguno de los pacientes declaró consumo de catinonas. El número de drogas implicadas en la intoxicación fue superior en el grupo CAT (3,5 [1,13] vs 2,5 [1,40]; p = 0,036). El perfil clínico del grupo CAT fue: varón (90,9%), consumidor de MANF (90,9%) y usuario de chemsex (45,5%). El diagnóstico de VIH se asoció significativamente al grupo CAT (45,5% vs 10,7%; p = 0,028). Los pacientes del grupo CAT presentaron mayor ansiedad (72,7% vs 21,4%; p = 0,007). No se hallaron diferencias en su manejo clínico. CONCLUSIONES: La detección de MANF debería considerarse un dato de sospecha de consumo de catinonas sintéticas, y en esos casos debería contemplarse la detección de nuevas sustancias psicoactivas de abuso.

Intento de suicidio con metanfetamina endovenosa y chemsex / Attempted Suicide with Intravenous Methamphetamine and Chemsex

RESUMEN Introducción: El trastorno de déficit de atención e hiperactividad no diagnosticado es una condición comórbida frecuente en los trastornos por abuso de sustancias, y tiene un importante impacto en la vida de los pacientes, pues incrementa el riesgo de abuso de sustancias y el riesgo derivado de conductas impulsivas. En el momento actual no existen trabajos que estudien la relación entre el TDAH y el fenómeno emergente del chemsex, es decir, el uso de sustancias psicoactivas en el contexto de fiestas sexuales para maximizar el tiempo de práctica sexual y de las experiencias subjetivas. En estas sesiones se usan diferentes sustancias como, por ejemplo, las catinonas sintéticas como la mefedrona, que podría inducir complicaciones médicas y psiquiátricas como psicosis, agresividad e ideación suicida. Caso: Un varón de 44 arios ingresó en la unidad de agudos de psiquiatría tras un segundo intento de suicidio de alto riesgo con el uso de metanfetamina endovenosa mezclada con un ácido queratolítico, en el contexto de un episodio depresivo y práctica activa de sesiones de chemsex con una frecuencia semanal, en las que tomaba mefedrona vía transrectal, que provoca episodios puntuales de psicosis tóxica autolimatada. Se objetivó clínica compatible con TDAH no diagnosticado, y se aplicaron ASRS-V1.1 y WURS, que indicaron TDAH. Se ajustó el tratamiento antidepresivo y remitieron los síntomas depresivos y la ideación autolítica. Discusión: La búsqueda de síntomas de TDAH «ocultos¼ en el contexto del abuso de sustancias es importante para no retrasar diagnósticos con importancia esencial y prevenir complicaciones. Complicaciones médicas y psiquiátricas relacionadas con la práctica del chemsex se han comunicado en Europa y recientemente en España, donde es un fenómeno emergente que preocupa. Se describen el intento de suicidio con metanfetamina, síntomas depresivos y psicóticos, abuso de sustancias y complicaciones médicas.

ABSTRACT Background: Undiagnosed attention deficit and hyperactivity disorder (ADHD) is frequent in the substance abuse disorder population, and has an intense repercussion in the daily life of the patients. That condition increases the risk of substance abuse disorders and risk conducts derived from impulsivity. There are not yet studies linking ADHD and the new emergent phenomenon of chemsex, that is, the action of use the intravenous injection of substances in sex parties, with the objective of maximising the practising time and sexual experience. In these sessions, different types of drug are used, for example, synthetic cathinone or mephedrone, and may lead to diverse medical and psychiatric complications like psychosis, aggressiveness and suicide ideation. Case: We report the case of a 44-year-old man admitted into a psychiatric unit, presenting with 2nd time suicidal high risk attempt using intravenous methamphetamine and a dissolvent acid in the context of a depressive episode, after practising chemsex sessions almost every weekend with psychoactive substances taken orally, intravenously and intrarectally. The patient also presented psychotic symptoms from the use of these drugs. When we interviewed the patient during his hospital stay, we observed that there were symptoms of a possible attention and hyperactivity deficit, which was confirmed by study with ASRS-V1.1 and WURS scales. After three weeks, the patient improved substantially as his depressive symptoms and autolytic ideation disappeared. Discussion: Look for "hidden" symptoms in substance abuse disorder patients. It is impor-tant not to delay important diagnostic tests and to prevent complications. Psychiatric and medical conditions related to chemsex have been reported in several European cities, and recently in Spain where it is an emergent phenomenon and a problem concerning medical and political institutions. The suicide attempt with metamphetamine and acid taken intravenously in the case we report, depressive and psychotic symptoms, addiction, suicide attempts and medical complications are described.

Relações entre o uso de anfetaminas e sintomas psicóticos: uma revisão sistemática / Relations between the use of amphetamines and psychotic symptoms: a systematic review

Anfetaminas são substâncias com ações no sistema nervoso central e periférico com potencial de causar dano intenso e de desencadear sintomas psicóticos (delírios, alucinações). Esta revisão procurou identificar trabalhos com informações essenciais para a compreensão das relações entre o uso dessas substâncias por indivíduos e o desenvolvimento de quadros psicóticos, tanto transitórios, ocorridos apenas durante o uso, quanto persistentes durante e após o período de abstinência, ou evoluindo para transtornos primários, como a esquizofrenia. Através de busca em dois bancos de dados foi possível selecionar as referências que supriram os objetivos. Diversas pesquisas buscaram desvendar os mecanismos de ação dessas drogas, e as bases neurológicas, bioquímicas, fisiológicas e moleculares dos transtornos psicóticos, procurando evidências das ligações entre as três situações citadas anteriormente, e similaridades significativas entre os quadros foram identificadas, incluindo em exames de neuroimagem e análises de quadros clínicos, além de comprovações estatísticas. Contudo, futuros estudos são necessários para esclarecer alguns aspectos desse tema e melhorar classificação etiológica, clínica e diagnóstica, além do manejo desses pacientes. [au]

Amphetamines are substances which act in the central and peripheral nervous system, with potential to cause intense damage and initiate psychotic symptoms (delusions, hallucinations). This review had as it's objetive identifying works with essential informations in order to understand the relations between the use of these substances by individuals and the development of psychotic conditions, both transient, happening only during use, and persistent, during and after abstinence, or when evolving to primary disorders, like schizophrenia. Through research in two databases, it was possible to select references that fullfilled the goals. Different researches sought to unravel the action mechanisms of these drugs, and the neurologicsl, biochemical, physiological and molecular bases of psychotic disorders, looking for evidence of connections between the three situations described previously, and significant similatities between the conditions were identified, including in neuroimaging exams and analysis of clinical presentations, besides statistical evidence. However, future studies are necessary to clarify some aspects of this topic and improve the etiological, clinical and diagnostic classification, plus the treatment of these patients. [au]

Amphetamine and methamphetamine poisonings attended in hospital emergency departments: clinical features and the usefulness of laboratory confirmation. / Intoxicaciones por anfetamina y metanfetamina atendidas en los servicios de urgencias: características clínicas y utilidad de la confirmación analítica.

OBJECTIVES: To determine whether clinical and toxicologic findings differed between cases of amphetamine (AMP) and methamphetamine (mAMP) poisoning attended in 2 Balearic Island hospital emergency departments. MATERIAL AND METHODS: Retrospective observational study of AMP and mAMP cases with laboratory confirmation between 2013 and 2018. We compared clinical and toxicologic variables as well as clinical management between groups. RESULTS: 1) A total of 120 cases were found: 86 (71.7%) with AMP poisoning and 34 (28.3%) with mAMP poisoning. 2) Drug poisoning was confirmed by gas chromatography associated with mass spectrometry (GC-MS) in 787 urine samples found to be positive during screening. One hundred fifty-four (19.6%) were confirmed by GC-MS. Thirtyfour of them did not meet the inclusion criteria. 3) Significant differences between AMP and mAMP cases were found for age (32.3 vs 28.4 y, respectively); sex (72.1% vs 94.1% men); and Spanish nationality (64.0% vs 29.4%). Reasons for admission and clinical features also differed: the reasons were aberrant behavior (15.1% in the AMP group vs 0% in the mAMP group) and palpitations (1.2% vs 20.6%); agitation was observed in 27.9% and 8.8%, respectively. Clinical management was similar in the 2 groups. Multiple drug poisoning was detected in 76.6% patients and was more common in patients in the AMP group (82.6% vs 61.8%). The additional drugs in these cases were mainly cocaine (63.0%), cannabis (48.9%), 3,4-methylenedioxy-N-methamphetamine (MDMA) (38.0%), and alcohol (35.9%). Cannabis was detected in a significantly higher proportion in the AMP group (45.3%) than in the mAMP group (17.6%). False positives were found in 78.7% of the samples. The culprit drug was most often MDMA (71.2%). CONCLUSION: AMP poisonings were associated with age over 30 years, Spanish nationality, aberrant behavior, agitation, multiple drug findings, and the use of cannabis. Poisonings caused by mAMP abuse were associated with age under 30 years, non-Spanish nationality, palpitations, and single-drug use.

OBJETIVO: Investigar si existen diferencias clínicas y toxicológicas en pacientes intoxicados por anfetamina (ANF) y metanfetamina (MANF) atendidos en servicios de urgencias. METODO: Estudio observacional retrospectivo de intoxicaciones por ANF y MANF con confirmación analítica en Baleares (2013-2018). Se compararon variables clínicas, toxicológicas y de manejo clínico entre grupos. RESULTADOS: 1) Se incluyeron 120 pacientes, 86 (71,7%) grupo ANF y 34 (28,3%) grupo MANF. 2) La confirmación de derivados anfetamínicos se realizó por cromatografía de gases-espectrometría de masas en 787 muestras de orina previamente positivas mediante un método de cribado cualitativo. Se confirmaron 154 (19,6%) muestras. De ellas, 34 fueron excluidas. 3) Se encontraron diferencias significativas entre ANF y MANF en: edad (32,3 vs 28,4 años); sexo (72,1 vs 94,1% hombres); nacionalidad española (64,0 vs 29,4%); en motivos de admisión: alteración de conducta (15,1 vs 0%) y palpitaciones (1,2 vs 20,6%); y en características clínicas: agitación (27,9 vs 8,8%). No hubo diferencias de manejo clínico. El 76,6% de casos fueron polintoxicaciones, más comunes en ANF (82,6 vs 61,8%). En estos casos se detectó principalmente cocaína (63,0%), cannabis (48,9%), MDMA (38,0%) y alcohol (35,9%). La mayor asociación del cannabis con el grupo de ANF fue estadísticamente significativa (45,3 vs 17,6%). La causa de los falsos positivos se identificó en el 78,7% de muestras, siendo el MDMA (71,2%) la principal. CONCLUSIONES: Se observaron diferencias entre ANF y MANF en cuanto a variables demográficas y motivo de asistencia; no obstante en esta serie hubo un alto porcentaje de polintoxicaciones.

Attempted Suicide with Intravenous Methamphetamine and Chemsex. / Intento de suicidio con metanfetamina endovenosa y chemsex.

BACKGROUND: Undiagnosed attention deficit and hyperactivity disorder (ADHD) is frequent in the substance abuse disorder population, and has an intense repercussion in the daily life of the patients. That condition increases the risk of substance abuse disorders and risk conducts derived from impulsivity. There are not yet studies linking ADHD and the new emergent phenomenon of chemsex, that is, the action of use the intravenous injection of substances in sex parties, with the objective of maximising the practising time and sexual experience. In these sessions, different types of drug are used, for example, synthetic cathinone or mephedrone, and may lead to diverse medical and psychiatric complications like psychosis, aggressiveness and suicide ideation. CASE: We report the case of a 44-year-old man admitted into a psychiatric unit, presenting with 2nd time suicidal high risk attempt using intravenous methamphetamine and a dissolvent acid in the context of a depressive episode, after practising chemsex sessions almost every weekend with psychoactive substances taken orally, intravenously and intrarectally. The patient also presented psychotic symptoms from the use of these drugs. When we interviewed the patient during his hospital stay, we observed that there were symptoms of a possible attention and hyperactivity deficit, which was confirmed by study with ASRS-V1.1 and WURS scales. After three weeks, the patient improved substantially as his depressive symptoms and autolytic ideation disappeared. DISCUSSION: Look for "hidden" symptoms in substance abuse disorder patients. It is important not to delay important diagnostic tests and to prevent complications. Psychiatric and medical conditions related to chemsex have been reported in several European cities, and recently in Spain where it is an emergent phenomenon and a problem concerning medical and political institutions. The suicide attempt with metamphetamine and acid taken intravenously in the case we report, depressive and psychotic symptoms, addiction, suicide attempts and medical complications are described.

Anti-NMDA (a-NMDAR) receptor encephalitis related to acute consumption of metamphetamine: Relevance of differential diagnosis. / Encefalitis antirreceptores (a-NMDAR) en un paciente con ingesta aguda de metanfetanima: importancia del diagnóstico diferencial.

A 19-year-old male came to the Emergency Room of our hospital due to an episode of dystonic movements and disorientation 4 days after consuming methamphetamine, which evolved to a catatonic frank syndrome and eventually to status epilepticus. Definitive diagnosis was anti-NMDA receptor encephalitis, an acute inflammation of the limbic area of autoimmune origin in which early diagnosis and treatment are key elements for the final outcome. In this case, initial normal tests and previous methamphetamine poisoning delayed diagnosis, because inhaled-methamphetamine poisoning causes similar clinical symptoms to anti-NMDA receptor encephalitis. Methamphetamine poisoning may have caused an immune response in the patient, bringing on the progress of the pathology.

Los nuevos empresarios: Trayectoria del uso a la venta de drogas en contextos de fiesta / The new businessmen: Pathways from drug use to drug dealing in party contexts

Drugs use at party contexts has increased in recent decades. Drugs dealing facilitates consumer access to substances, whose sales practices vary according to drugs use, places for the consumption and the drug social function. Drug dealing is socially constructed from a set of practices ranging from reasons to dealing and those related to the consolidation as a common practice. The aim of this research was to describe and analyze the drugs users' experience in party contexts, about their dealer's construction process. An interpretative multiple-case study with the snowball technique was carried out to get the participants. The information was obtained by a semi-structured interview and nonparticipant observation at the dealing places. The information obtained points out the group's participation on the selection of the dealer as the initiation of drugs dealing, the extroversion features and communication skills as an important profile to be a dealer; specially, the capability to satisfy the group's emotional request through the drugs. Also, benefits as acceptation, protection and the warmth from the group and the economical earning. The dealer/businessmen consolidation is socially constructed according to the new identity assumed, the group participation and the specific activities as a business.

El uso de drogas en contextos de fiesta se ha incrementado en las últimas décadas. El narcomenudeo facilita el acceso a sustancias de consumo, cuyas prácticas de venta varían conforme a la droga de uso, los espacios de consumo y la función de la droga en los grupos que la consumen. La venta de drogas implica una serie de prácticas que la construyen y que incluyen los motivos del inicio de venta, el proceso de desarrollo y las relacionadas con la consolidación de la venta como práctica habitual. El objetivo de esta investigación fue describir y analizar la experiencia de usuarios de drogas en contextos de fiesta respecto al proceso en que se construyen como dealers. Para lo anterior, se realizó un estudio interpretativo de casos múltiples, empleando la técnica de "bola de nieve" para captar a los participantes. La observación se obtuvo por medio de una entrevista semiestructurada y la observación no participante en escenarios de venta. Se obtuvo información relacionada con los elementos del salto del uso a la venta como la elección del dealer por el grupo, su perfil para ser elegido como la extroversión y habilidades de comunicación; y sobre todo su capacidad para satisfacer la demanda de emociones de los miembros de su grupo por medio de las drogas de venta. Además, de la aceptación, protección y afecto del grupo y las ganancias económicas. La consolidación como dealer/empresario se construye conforme se asumen una nueva identidad, la participación del grupo y las actividades específicas de la empresa.

Consequências do uso de cocaína e metanfetamina durante a gravidez / Consequences of cocaine and methamphetamine during pregnancy

Com o objetivo de descrever as consequências do uso da cocaína e metanfetamina durante a gestação, foi realizada revisão crítica das publicações nas seguintes bases de dados: MEDLINE (por meio do PubMed), SciELO, LILACS e Google acadêmico, utilizando-se termos e palavras-chave relacionadas à cocaína, metanfetamina e gestação. O uso desses estimulantes do sistema nervoso central constitui-se em grave problema de saúde pública passível de intervenção, a qual pode reduzir ou até mesmo evitar agravos à saúde da gestante e do feto, além de redução dos gastos públicos com os longos períodos de internação e recuperação da saúde dos usuários. Foram observadas alterações no desenvolvimento infantil, diminuição de atividade motora e dificuldade de sustentar atenção com o uso metanfetamina. Bebês nascidos de mães que abusaram de cocaína durante a gravidez geralmente nascem de parto prematuro, com baixo peso e estatura e circunferência craniana menor do que o normal. Observam-se, ainda, altas taxas de malformação congênita e de mortalidade perinatal. Há também evidências mostrando queda no rendimento escolar, envolvendo distração e déficit de atenção, em crianças cujas mães usaram cocaína na gravidez. Entretanto, muitas dúvidas sobre o assunto ainda permanecem, merecendo maior atenção, em vista da importância do efeito dessas drogas no período gestacional e a repercussão futura no desenvolvimento infantil.

In order to describe the effects of using cocaine and methamphetamine during pregnancy was performed a review of published studies on the threshold of medical data base: MEDLINE (PubMed), SciELO, LILACS and Google scholar, using terms and keywords related to cocaine, methamphetamine and pregnancy. The use of central nervous system stimulants is a serious public health problem susceptible to intervention, which can reduce or even prevent damages to health of the mother and fetus, and reduce public spending long periods of hospitalization and recovery of users’ health. Changes were observed in child development, decreased visual-motor performance and difficulty sustaining attention using methamphetamine. Babies born to mothers who abused of cocaine during pregnancy are often born of premature births, low weight and height and head circumference smaller than normal. There are also high rates of congenital malformation and perinatal mortality. There is also evidence that children who received cocaine through their mothers in the intrauterine stage can have falling in school performance, involving distraction and difficulty concentrating. However, many questions still remain about the issue, deserving more attention, in view of the importance of the effect of these drugs during pregnancy and its future impact on child development.
