Cutaneous and Mucosal Conditions Associated With Cocaine Use. / Cuadros cutáneo-mucosos asociados al consumo de cocaína.

Cocaine and some of its main adulterants, such as levamisole, can cause multiple cutaneous and mucosal manifestations, including ischemic complications, neutrophilic dermatoses, midline destructive lesions, and vasculitis associated with antineutrophil cytoplasmic antibodies (ANCAs). Striking systemic symptoms are generally not seen. In all these conditions, positive test results may be observed for antinuclear antibodies, antiphospholipid antibodies, and various ANCAs, sometimes with characteristic staining patterns. Histology typically shows vascular changes, such as leukocytoclastic vasculitis, necrotizing vasculitis, and thrombi. We review the clinical, serologic, and histologic features of cutaneous and mucosal conditions associated with the use of cocaine and also look at pathophysiologic mechanisms, differential diagnoses, and treatments.

Cocaine-related ischemic priapism. Systematic review and presentation of a single center series.

INTRODUCTION: Ischemic priapism is a medical emergency that, if not treated, could lead to permanent erectile dysfunction. The association between cocaine and priapism is well-known; however, data on patient characteristics, treatment, and outcomes is missing. This work aimed to answer the research question: What are the characteristics, management strategies, and erectile prognosis of patients consuming cocaine and presenting with priapism? METHODS: We conducted a systematic review according to PRISMA guidelines and described our case series. RESULTS: Eight studies were selected for qualitative synthesis, presenting information on ten patients. In our case series, we showed information regarding four patients. From the systematic review, the mean presentation time was 42.6 h, and the mean number of procedures to solve priapism was 2,4; in our case series was 42.75 h and 2, respectively. CONCLUSION: Cocaine-related priapism might present with a delayed diagnosis, need more procedures to be managed, and have a worse prognosis. More extensive and prospective studies are required.

[Substance use disorder: Epidemiology, medical consequences and treatment]. / Trastorno por uso de sustancias: epidemiología, complicaciones médicas y tratamiento.

Substance use is a common health problem, and substance use disorder, which is its most severe presentation, is associated with multiple medical consequences and a negative impact on individual and on population health. Substance use disorder needs to be addressed as any chronic medical condition; therefore, it has to be detected at the early stages and has to be properly treated to prevent drug-related harm. Internists should be able to recognize and treat intoxication and abstinence. Internists should also be able to refer the patient to state of the art long term treatment, aimed to detoxification and treatment induction to promote abstinence and prevent relapse. In this narrative review we will discuss substance use epidemiology, its main medical consequences and its treatment, with a focus on alcohol, opiates, cocaine and other stimulants, cannabis and benzodiazepines.

Chest pain secondary to drug use treated in hospital emergency departments in Spain.

OBJECTIVE: To determine the characteristics of patients with chest pain (CP) associated with recent drug use. METHODS: Study of cases from the REUrHE registry attended in the emergency department of 11 Spanish hospitals for CP following recreational drug use. RESULTS: CP accounted for 8.97% of attendances (males 82.9%, p<0.001). Cocaine was present in 70% of cases, followed by cannabis (35.7%) and amphetamines and derivatives (21.4%). The most frequent initial symptoms were: palpitations (45.5%, p<0.001), anxiety (42.5%, p<0.001), hypertension (13.6%, p<0.001) and arrhythmias (5.9%, p<0.001). Patients with TD received more treatment (81.9% vs 74.1%; p<0.001), although they were admitted less (7.6%, p=0.0), with no differences in terms of CPR manoeuvres, sedation, intubation, or admission to intensive care (1.9%). CONCLUSIONS: In CP following acute drug intoxication, cocaine use predominates, although cases of cannabis use are increasing.

Optical neuropathy due to inhaled cocaine, causality or chance. / Neuropatía óptica secundaria a consumo de cocaína inhalada. Causalidad o casualidad.

A 44-year-old man, active cocaine consumer, who referred decrease in visual acuity in the right eye in 24 hours of evolution, being 0,05 in that eye and 1 in the left eye. The examination showed a relative afferent pupil defect and a swelling head of optic nerve. The systemic studies performed were normal, except the nuclear magnetic resonance of the brain that showed a thickening of the maxillary and frontal sinus mucosa, compatible with sinusitis. Hospital admission and the start of intravenous corticosteroid treatment were decided, with a favourable evolution, a visual acuity of 1.0 in both eyes and an anatomical improvement of the optic nerve head. Due to the medical history of the patient and the assessment of other plausible alternative diagnoses, we established the diagnosis of optical neuropathy due to inhaled cocaine abuse.

Pulmonary-renal syndrome secondary to cocaine-levamisole-induced vasculitis: A case report. / Síndrome pulmón-riñón secundario a vasculitis por cocaína/levamisol: reporte de caso.

Pulmonary-renal syndrome has rarely been reported as the clinical presentation of vasculitis caused by the consumption of cocaine adulterated with levamisole. We report the case of a patient in whom we detected the clinical manifestations and indicate the difficulties that arose in relation to the diagnostic and therapeutic approach.

Relapse in involuntary substance treatment: a transversal study.

OBJECTIVE: To evaluate the associations between relapse and admissions (voluntary and involuntary) in a sample of patients with substance dependence. METHODS: This is a cross-sectional study undertaken at a private medical therapeutic community specialised in treating addiction, located in a rural area of São Paulo, Brazil. Sociodemographic characteristics, the University of Rhode Island Change Assessment Scale (URICA), Stages Readiness and Treatment Eagerness Scale (SOCRATES), Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) and Structured Clinical Interview for DSM-IV-SCID were used. RESULTS: Relapse was associated with low family income (P=.006) and contemplation motivational stage (P<0.05). Nevertheless, no significant differences between individuals who were admitted involuntarily (64%) and voluntarily (54%) were observed (P=0.683) in terms of relapses. CONCLUSIONS: In this sample, the relapse outcome in involuntary admissions was no different from the voluntary ones.

El secuestro de la voluntad: bases moleculares de los cambios plásticos en la adicción / The hijacking of the will: molecular bases of plastic changes in addiction

Todas las drogas de abuso tienen en común la activación del sistema cerebral del placer. Los análisis imagenológicos han arrojado resultados de cambios estructurales en el cerebro de adictos a la cocaína e imágenes cerebrales en sujetos adictos muestran una disminución de la producción de dopamina que lleva a que la acción esté notoriamente amortiguada en relación con controles. Los estudios estructurales han mostrado reducciones de volumen de la sustancia gris y alteraciones circuitales de la sustancia blanca en el lóbulo frontal de adictos. La transición del uso recreativo a la adicción se asocia con cambios en la función de las neuronas que se acumulan con la administración repetida. La exposición crónica a la cocaína provoca aumentos de la arborización y de la densidad de las espinas dendríticas. El aumento de capacidad sináptica, ante el estímulo subcortical de una nueva presencia de la droga, toma el control de las funciones ejecutivas, «secuestrando¼ la capacidad de la voluntad consciente.

The activation of of the brain pleasure system is common to all abuse drugs. Imaging analyses have shown structural changes in the brain of cocaine addicts and a reduction of dopamine production which causes attenuation of its action when compared to control subjects. Structural studies in these patients show gray matter reduction and circuitry changes in frontal lobe white matter. Transition from recreational use to addiction is associated with changes in neuronal function which accumulate with repeated administration. Chronic exposure to cocaine leads to an increase in arborization and density of dendritic spines. When faced with new subcortical presence of the drug, the increase of synaptic capacity takes control of executive functions, "sequestering" the capacity for conscious will.

Alterações sistêmicas e bucais em pacientes usuários de cocaína: uma revisão integrativa da literatura / Cambios sistémicos y orales em pacientes consumidores de cocaína: una revisión bibliográfica integradora / Systemic and oral changes in cocaína-using patients: an integrative literature review

Introdução: A utilização de cocaína é bastante associada ao surgimento de algumas manifestações sistêmicas e também de algumas alterações orais. Objetivo: Identificaras alterações sistêmicas e bucais mais comuns a pacientes usuários de cocaína. Metodologia: Trata-se de uma revisão sistemática da literatura, considerando artigos com texto completo, com restrição de idioma em Português ou Inglês e que tenham sido publicados entre os anos de 2017 a 2022. Usou-se as bases de dados LiLaCS, MedLine e BBO, por via portal Biblioteca Virtual de Saúde, e SciELO. Os artigos excluídosf oram aqueles que não apresentaram relação explícita do uso de cocaína com alguma manifestação sistêmica e/ou bucal. Resultados: Após o processo de triagem,10 artigos foram salvos para serem analisados e 111 foram descartados por não atenderem aos critérios de inclusão. Dos 10 artigosselecionados,40% deles (n=4) trouxeram informações identificando possíveis riscos de desenvolvimento de doenças cardiovasculares sofridas pelos usuários de cocaína, 10%(n=1) identificou problemas cognitivos associados ao uso da cocaína,30% dos artigos (n=3) mostrou as alterações bucais associadas à utilização abusiva de cocaína. Conclusões: Houve a predominância de algumas manifestações sistêmicas e bucais nos indivíduos usuários de cocaína, como doenças cardiovasculares, xerostomia, perfurações no palato, etc. A partir disso, há algumas alterações sistêmicas e bucais provocadas por esse uso. Mediante o risco considerável, faz-se necessário que o Cirurgião-Dentista se atualize sobre essas alterações em pacientes usuários de cocaína visando promover um trabalho transdisciplinare multiprofissional para atender adequadamente às suas necessidades (AU).

Introduction: The use of cocaine is closely associated with the appearance of some systemic manifestations and also some oral alterations.Objective: To identify the most common systemic and oral alterations in cocaine-using patients.Methodology:This is a systematic review of the literature, considering full-text articles, with a language restriction of "Portuguese" or "English" and published between 2017 and 2022. We used the LiLaCS, MedLine and BBO databases, via the Virtual Health Library (VHL) portal, and SciELO.The articles excluded were those that did not explicitly relate cocaine use to some systemic and/or oral manifestation.Results: After the screening process, 10 articles were saved for analysis and 111 were discarded because they did not meet the inclusion criteria. Of the 10 articles selected, 40% (n=4) provided information identifying possible risks of developing cardiovascular diseases suffered by cocaine users, 10% (n=1)identified cognitive problems associated with cocaine use, 30% of the articles (n=3) showed oral alterations associated with cocaine abuse.Conclusions: There has been a predominance of some systemic and oral manifestations in cocaine users, such as cardiovascular diseases, xerostomia, perforations in the palate, etc. Based on this, there are some systemic and oral alterations caused by this use. Given the considerable risk, it is necessary for dentists to be up-to-date on these alterations in cocaine-using patients in order to promote transdisciplinary and multi-professional work to adequately meet their needs (AU).

Emergency department visits for transient global amnesia alone or in association with substance abuse. / Amnesia global transitoria y consumo de tóxicos que motivan la consulta al servicio de urgencias.

OBJECTIVES: To study the epidemiology of emergency department visits for transient global amnesia (TGA) by itself or associated with substance abuse or sexual assault. MATERIAL AND METHODS: Retrospective study of cases treated from January to December 2018. Data for all patients with TGA were extracted, and cases were classified as associated with substance abuse (TGASUB), sexual assault (TGASEX), or neither (TGAONLY). RESULTS: A total of 287 TGA cases were found: 169 (58.9%) were TGASEX, 62 (21.6%) TGAONLY, and 56 (19.5%) TGASUB. Two hundred eighteen (76%) were female and 69 (24%) were male. Ages ranged from 16 to 90 years; 174 (60.6%) were under the age of 30 years. Two hundred one patients (72.8%) reported consuming alcohol; and 105 (49.1%) were positive on testing (mean blood alcohol concentration, 0.74 g/L; maximum, 3.9 g/L. Twenty patients (7.1%) reported using cannabis, and 39 (17.3%) had positive test results; 14 reported using cocaine (4.9%) and 28 (12.4%) tested positive; 5 (1.7%) reported using amphetamines and 20 (8.8%) tested positive. Fifty-eight (20.1%) had symptoms of intoxication. Four were admitted in coma. A computed tomography scan was ordered for 66 patients (23%), 7 patients were hospitalized, and none died. CONCLUSION: The prevalence of TGA is higher if cases of substance abuse and sexual assault are counted. Toxicolgy testing changes the epidemiology of TGA in emergencies.

OBJETIVO: Conocer la epidemiología de las consultas en urgencias por amnesia global transitoria (AGT), ya sea pura, asociada al consumo de tóxicos o en el contexto de una agresión sexual. METODO: Estudio retrospectivo de enero a diciembre de 2018. Se revisaron las AGT atendidas en intoxicados (AGTtox), en víctimas de agresiones sexuales (AGTsex) y las amnesias puras (AGTpur), evaluando la presencia de tóxicos. RESULTADOS: Se identificaron 287 AGT: 169 AGTsex (58,9%), 62 AGTpur (21,6%) y 56 AGTtox (19,5%). De ellas, 218 (76%) fueron mujeres y la edad osciló entre 16 y 90 años (60,6% menores de 30 años). Reconocieron consumo de alcohol 201 casos (72,8%), con etanolemia positiva en 105 (49,1%) (media de 0,74 g/l y máxima de 3,9 g/l). Admitieron consumo de cannabis 20 pacientes (7,1%), con analítica positiva en 39 casos (17,3%); cocaína 14 (4,9%), con analítica positiva en 28 (12,4%), y anfetaminas 5 (1,7%), con analítica positiva en 20 (8,8%). Presentaron síntomas de intoxicación 58 casos (20,1%). Cuatro pacientes ingresaron en coma. Se realizó una tomografía computarizada (TC) craneal a 66 pacientes (23%), se hospitalizaron 7 y no hubo ningún fallecimiento. CONCLUSIONES: La prevalencia de AGT es mayor si se incluyen los intoxicados y las agresiones sexuales, modificando la determinación de tóxicos la epidemiología de la AGT en urgencias.

Telephone counseling for young Brazilian cocaine and/or crack users. Who are these users?

OBJECTIVE: To describe the users' drug abuse characteristics, problematic behaviors associated with addiction, the motivation of teenagers and young adults to quit cocaine and/or crack abuse, and then compare these characteristics. METHODS: A cross-section study was conducted with 2390 cocaine/crack users (teenagers from 14 to 19 years of age, and young adults from 20 to 24 years of age); 1471 were young adults and 919 were teenagers who had called a phone counseling service between January 2006 and December 2013. Semi-structured interviews were performed via phone calls. The questionnaires included sociodemographic information; assessment of the characteristics of cocaine/crack abuse; assessment of the problematic behaviors; also, the Contemplation Ladder was used to evaluate the stages of readiness to cease substance abuse. RESULTS: Participants reported using cocaine (48.2%), crack and other smoking forms (36.7%) and combined consumption of both drugs (15%). Young adults were more prone to using crack or crack associated with cocaine (OR=1.9; CI 95%=1.05-1.57) and they were exposed to substance abuse for longer than two years (OR=3.45; CI 95%=2.84-4.18), when compared to teenagers. On the other hand, they showed higher readiness to quit. CONCLUSION: Data shows important differences in drug abuse characteristics, problematic behaviors and motivation to cease substance abuse between teenager and young adult cocaine and/or crack users. Behaviors displayed by young adults involve greater physical, mental and social health damages. These findings reinforce the importance of public policy to act on prevention and promoting health, to increase protection factors among teenagers and lower risks and losses during adult life.

Syndrome of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis (HaNDL) in a patient with confusional symptoms, diffuse EEG abnormalities, and bilateral vasospasm in transcranial Doppler ultrasound: A case report and literature review. / Síndrome de cefalea transitoria con déficits neurológicos asociados y pleocitosis en líquido cefalorraquídeo (HaNDL) con cuadro confusional, EEG compatible con afectación difusa y datos de vasoespasmo bilateral en estudio Doppler transcraneal: presentación de un caso y revisión de la literatura.

INTRODUCTION: HaNDL syndrome (transient headache and neurological deficits with cerebrospinal fluid lymphocytosis) is characterised by one or more episodes of headache and transient neurological deficits associated with cerebrospinal fluid lymphocytosis. To date, few cases of HaNDL manifesting with confusional symptoms have been described. Likewise, very few patients with HaNDL and confusional symptoms have been evaluated with transcranial Doppler ultrasound (TCD). TCD data from patients with focal involvement reveal changes consistent with vasomotor alterations. DEVELOPMENT: We present the case of a 42-year-old man who experienced headache and confusional symptoms and displayed pleocytosis, diffuse slow activity on EEG, increased blood flow velocity in both middle cerebral arteries on TCD, and single-photon emission computed tomography (SPECT) findings suggestive of diffuse involvement, especially in the left hemisphere. CONCLUSIONS: To our knowledge, this is the first description of a patient with HaNDL, confusional symptoms, diffuse slow activity on EEG, and increased blood flow velocity in TCD. Our findings suggest a relationship between cerebral vasomotor changes and the pathophysiology of HaNDL. TCD may be a useful tool for early diagnosis of HaNDL.

Near-fatal cocaine intoxication in an infant with thrombotic microangiopathy associated with multiple organ failure / Intoxicação grave por cocaína em criança com microangiopatia trombótica associada à falência múltipla de órgãos

ABSTRACT Objective: To report a pediatric case of drug-induced thrombotic microangiopathy caused by cocaine Case description: We report a nine-month-old patient who developed thrombotic microangiopathies after extreme cocaine intoxication, multiple organ dysfunction syndrome with hemodynamic dysfunction, anuric renal failure, liver failure, encephalopathy, and myocardial injury, corresponding phenotypically to thrombocytopenia-associated multiple organ failure. The patient received continuous venous hemofiltration and therapeutic plasma exchange, recovering satisfactorily. She was discharged after 30 days of hospitalization under the guidance of the childcare service, and was healthy after one year of follow-up. Toxicological samples confirmed high levels of cocaine and derivatives in blood, urine and hair. Comments: To our knowledge, this is the first reported pediatric case. There are particularities of cocaine intoxication pathophysiology that can trigger thrombotic microangiopathies because of vasoconstriction, direct endothelial injury, platelet activation, and increasing von Willebrand factor and fibrinogen levels. All of which results in a prothrombotic state, inflammatory dysregulation, and microvascular thrombi. The increasing use of cocaine, especially among young adults, puts children at high risk of toxicity, either by passive unintentional exposure, or abuse due to the increased availability in homes.

RESUMO Objetivo: Relatar um caso pediátrico de microangiopatia trombótica induzida por drogas causada por cocaína Descrição do caso: Relatamos uma paciente de nove meses de idade que desenvolveu microangiopatia trombótica após intoxicação extrema por cocaína, síndrome de disfunção de múltiplos órgãos com disfunção hemodinâmica, insuficiência renal anúrica, insuficiência hepática, encefalopatia e lesão miocárdica, correspondendo fenotipicamente à falência múltipla de órgãos associada à trombocitopenia. A paciente recebeu hemofiltração venosa contínua e plasmaférese terapêutica, recuperando-se satisfatoriamente. Recebeu alta após 30 dias de internação sob orientação do serviço de puericultura e estava saudável após um ano de seguimento. Amostras toxicológicas confirmaram altos níveis de cocaína e derivados no sangue, urina e cabelos. Comentários: Até onde sabemos, este é o primeiro caso pediátrico relatado. Existem particularidades da fisiopatologia da intoxicação por cocaína que podem desencadear a microangiopatia trombótica devido à vasoconstrição, lesão endotelial direta, ativação plaquetária e aumento do fator de von Willebrand e dos níveis de fibrinogênio. Tudo isso resulta em um estado pró-trombótico, desregulação inflamatória e trombos microvasculares. O uso crescente de cocaína, principalmente entre adultos jovens, coloca as crianças em alto risco de toxicidade, seja por exposição passiva não intencional ou abuso devido à maior disponibilidade nas residências.

Materials and methods. Data were collected from the Forensic Pathology Section of the Legal Medicine Department in Costa Rica, then a review of fatalities due to acute poisoning was carried out from January 1, 2012 to December 31, 2021. The review included the following epidemiological variables: sex, age, nationality, occupation, marital status, province, consumption associated, manner of death, type of substance, and place of intoxication. Results. Out of the 456 reported cases of deaths associated with acute intoxication with ethanol, methanol, benzodiazepines, amphetamines, heroin, cocaine, and mixed substances between January 1, 2012, and December 31, 2021: the year with the highest number of cases reported was 2020; 82% of the victims were male, and 18% were female; the main age group of reported victims ranged from 41 to 60 years old. 80% of the victims were Costa Rican, and San Jose was the province with the highest number of lethal intoxication cases, with the home being the most frequent site. 14% of the victims were unemployed, and 77% of the individuals had some addiction disorder or frequent consumption of one of the studied substances. The majority of deaths were accidental. Conclusion. The main profile of the victims was male, between 41 and 60 years old, Costa Rican, of indeterminate or single marital status, unemployed, who died accidentally, at home, due to acute intoxication with alcohol or a mixture of substances (alcohol and cocaine).

Representações Sociais do planejamento da maternidade em gestantes usuárias de drogas / Social representations of maternity planning in pregnant drug users / Representaciones sociales de la planificación de la maternidad en embarazadas usuarias de drogas

Objetivo: compreender as Representações Sociais do planejamento e do desejo de exercer a maternidade em gestantes usuárias de drogas que vivencia/vivenciou a gravidez na adolescência. Método: estudo qualitativo, descritivo, fundamentado na Teoria das Representações Sociais. Foram entrevistadas 10 adolescentes que vivenciaram a gestação e o uso de drogas. A análise dos dados foi realizada a partir da Análise Textual Discursiva. Resultados: os resultados apontaram falta de conhecimento sobre aspectos da vida sexual e uso de anticoncepcionais. A droga ocupou o espaço vazio de solidão e medo, sendo uma forma encontrada pelas adolescentes de lidar com os problemas da vida. Apesar de muitas não terem planejado a gestação, esse processo motivou a diminuição do uso da substância. Conclusão: o estudo revelou a necessidade de diálogo sobre o processo gestacional na adolescência e uso de drogas, bem como, a importância de pesquisas e ações governamentais que abordem este problema de saúde pública

Objective: to understand the Social Representations of planning and the desire to exercise motherhood. Method: qualitative, descriptive study, based on the Theory of Social Representations.10 adolescents who experienced pregnancy and drug use were interviewed. Data analysis was performed using Discursive Textual Analysis. Results: lack of knowledge about aspects of sexual life and use of contraceptives was observed. The drug occupied an empty space of loneliness and fear, a found way of dealing with life's problems. Although many did not plan the pregnancy, this process motivated the decrease in substance use/dependence. Conclusion: the study revealed the need for dialogue about the pregnancy process in adolescence and drug use, as well as the importance of research that problematize this public health problem

Pancreatitis aguda asociada a cocaína, una complicación inusual. Serie de casos / Cocaine-induced acute pancreatitis, an unusual complication. Case serie / Pancreatite aguda associada à cocaína, uma complicação incomum. Número de casos

La cocaína es una de las sustancias ilegales más consumidas y Colombia no es la ex­cepción. Dentro de las sustancias ilegales es la segunda más consumida después del cannabis. Por su mecanismo mismo de acción, que produce aumento de aminas bióge­nas, se han asociado con la cocaína diferentes riesgos, tanto agudos como crónicos, y dentro de sus complicaciones se han descrito cambios comportamentales, compromiso cardiovascular y neurológico. La coingesta de cocaína y alcohol da lugar a un metabolito conocido como cocaetileno, que lleva a complicaciones cardiovasculares. Poco se ha descrito sobre el riesgo de la cocaína o la coingesta cocaína y alcohol, como un factor sumatorio, para la pancreatitis. Reportamos tres pacientes jóvenes consumidores del alcaloide que desarrollaron pancreatitis aguda, dos de ellos murieron. El objetivo de este reporte es sensibilizar a los trabajadores de la salud sobre otro riesgo para considerar en los pacientes consumidores de cocaína.

Cocaine is one of the most consumed illegal substances and Colombia is no exception. It is the second most consumed among the illegal substances after cannabis. Due to its very mechanism of action, which produces an increase in biogenic amines, different risks, both acute and chronic, have been associated with cocaine, and among its complications, behavioral changes, cardiovascular and neurological compromise have been described. The co-ingestion of cocaine and alcohol gives rise to a metabolite known as cocaethylene, which leads to cardiovascular complications. Little has been described about the risk of cocaine or cocaine and alcohol co-ingestion, as a summative factor, for pancreatitis. We report three young patients consuming the alkaloid who developed acute pancreatitis, two of whom died. The objective of this report is to sensitize health workers about another risk to consider in cocaine-consuming patients.

A cocaína é uma das substâncias ilícitas mais consumidas e a Colômbia não é exceção. Dentro das substâncias ilícitas é a segunda mais consumida depois da maconha. Devido ao seu próprio mecanismo de ação, que produz aumento de aminas biogênicas, diversos riscos, tanto agudos quanto crônicos, têm sido associados à cocaína e, entre suas complicações, têm sido descritas alterações comportamentais, comprometimento cardiovascular e neurológico. A co-ingestão de cocaína e álcool dá origem a um metabólito conhecido como cocaetileno, que leva a complicações cardiovasculares. Pouco tem sido descrito sobre o risco da co-ingestão de cocaína ou cocaína e álcool, como fator somativo, para pancreatite. Relatamos 3 pacientes jovens consumindo o alcalóide que desenvolveram pancreatite aguda, dois dos quais morreram. O objetivo deste relatório é sensibilizar os profissionais de saúde sobre outro risco a ser considerado em pacientes consumidores de cocaína.

[Right spermatic vein thrombosis. Revision of literature regarding a specific case]. / Trombosis de la vena espermática derecha. Revisión de la literatura a propósito de un caso.

Acute thrombophlebitis of spermatic vein is an unusual pathology involving, in most of the cases, the left side, and whose etiology remains uncertain. Most of them are found during a a differential diagnosis in acute testicular pain. We introduce the case of a 29 years old male with abusive cocaine consumption, admitted to hospital due to severe testicular pain. Doppler-ultrasound examination was undertaken, showing right spermatic vein flux alteration. Conservative management was decided and anticoagulant and non-esteroidal anti-inflammatory drugs were started. Eco-doppler is the most specific and sensible technique for diagnosis of these cases, while TC can always confirm etiologic diagnosis. Treatment was initially conservative based on anticoagulation. Hematological study is necessary in order to determine coagulation alterations.

Cocaine-induced stroke in a young patient / Acidente vascular cerebral induzido por cocaína em paciente jovem

The case report presented here addresses the relationship between cocaine use and stroke. A young adult patient arrived at a specialized unit with neurological deficits and a history of acute and long-term illicit drug use and presented no other comorbidities. In addition, he presented laboratory and serological tests without alterations. The only risk factor identified for stroke was, therefore, cocaine use. Thus, this work points to an eventual relationship between cocaine use and the case in question (AU).

O relato de caso apresentado neste trabalho, aborda a relação do uso da cocaína e o acidente vascular cerebral após um paciente adulto jovem chegar a uma unidade especializada com déficits neurológicos e histórico de uso de drogas ilícitas de forma aguda e de longa data, sem outras comorbidades constatadas. Além disso, apresentou exames laboratoriais e sorológicos sem alterações significativas. O único fator de risco identificado no caso em tela para o acidente vascular foi, portanto, o uso de cocaína. Assim, neste trabalho, enfatiza-se eventual relação entre o uso da cocaína com o caso em tela (AU).

Hematoma cerebral intraparenquimatoso e intraventricular por cocaína: reporte de un caso

Introducción: La cocaína es una de las sustancias psicoactivas más consumidas mundialmente. Es altamente adictiva y puede producir cuadros graves por su consumo, esporádico o habitual o, por su abstinencia, a nivel sistémico y neurológico. La exposición aguda a esta sustancia desencadena manifestaciones psiquiátricas inmediatas, como cambios en el afecto o conducta: sensación de irritabilidad, hiperactividad, ansiedad, desasosiego, euforia o psicosis. Esta sintomatología contrasta con inducción en ciertos casos de depresión, aislamiento o tristeza con la cronificación en su consumo. Además de los diversos efectos sensoperceptuales descritos, la sustancia puede generar daños neurológicos y/o cardiovasculares graves, como trastornos del ritmo cardíaco, arritmias malignas, emergencias hipertensivas, síndromes coronarios y enfermedades cerebrovasculares. Métodos: Presentamos el caso de un paciente quien ingresó al Hospital Universitario del Valle, en la ciudad de Santiago de Cali, departamento del Valle del Cauca, en Colombia, por un cuadro neurológico que permitía sospechar origen central. Este paciente no tenía factores de riesgo cardiovasculares, pero sí antecedentes de síndrome de Guillain Barré y de consumo de cocaína desde su adolescencia. Resultados: Al mencionado paciente se le realizaron múltiples estudios, destacándose los imagenológicos (tomografía, resonancia y angiorresonancia magnética de cerebro) y la estrategia invasiva de angiografía cerebral, en la cual logró documentarse que las manifestaciones neurológicas del paciente obedecían a una enfermedad cerebrovascular hemorrágica severa secundaria al consumo de cocaína. Conclusiones: Siempre indagar en pacientes con sangrados intraparenquimatosos el consumo de psicoactivos, en especial la cocaína, por su efecto lesivo sobre la vasculatura cerebral.

Introduction: Cocaine is one of the most widely consumed psychoactive substances worldwide. It is highly addictive and can produce serious systemic and neurological symptoms due to sporadic or habitual use or withdrawal. Acute exposure to this substance triggers immediate psychiatric manifestations such as changes in affect or behavior: feelings of irritability, hyperactivity, anxiety, restlessness, euphoria or psychosis; this symptomatology contrasts with induction in certain cases of depression, isolation or sadness with the chronification of its consumption. In addition to the various sensory-perceptual effects described, the substance can cause serious neurological and/or cardiovascular damage, such as heart rhythm disorders, malignant arrhythmias, hypertensive emergencies, coronary syndromes and cerebrovascular diseases. Methods: We present the case of a patient who was admitted to the Hospital Universitario del Valle, in the city of Santiago de Cali, department of Valle del Cauca, in Colombia, for a neurological condition that suggested a central origin. This patient had no cardiovascular risk factors, but had a history of Guillain Barré syndrome and cocaine use since adolescence. Results: The aforementioned patient underwent multiple studies, highlighting the imaging studies (CT, MRI and MRA of the brain) and the invasive strategy of cerebral angiography, in which it was possible to document that the patient's neurological manifestations were due to severe hemorrhagic cerebrovascular disease secondary to cocaine consumption. Conclusions: Always inquire in patients with intraparenchymal bleeds the consumption of psychoactives, especially cocaine, for its injurious effects on the cerebral vasculature.
