RESUMEN

BACKGROUND: Little is known about the incidence of delirium and its subtypes in patients admitted to different departments of university hospitals in Latin America. OBJECTIVE: To determine the incidence of delirium and the frequency of its subtypes, as well as its associated factors, in patients admitted to different departments of a university hospital in Bogotá, Colombia. METHODS: A cohort of patients over 18 years of age admitted to the internal medicine (IM), geriatrics (GU), general surgery (GSU), orthopaedics (OU) and intensive care unit (ICU) services of a university hospital was followed up between January and June 2018. To detect the presence of delirium, we used the CAM (Confusion Assessment Method) and the CAM-ICU if the patient had decreased communication skills. The delirium subtype was characterised using the RASS (Richmond Agitation and Sedation Scale). Patients were assessed on their admission date and then every two days until discharged from the hospital. Those in whom delirium was identified were referred for specialised intra-institutional interdisciplinary management. RESULTS: A total of 531 patients admitted during the period were assessed. The overall incidence of delirium was 12% (95% CI, 0.3-14.8). They represented 31.8% of patients in the GU, 15.6% in the ICU, 8.7% in IM, 5.1% in the OU, and 3.9% in the GSU. The most frequent clinical display was the mixed subtype, at 60.9%, followed by the normoactive subtype (34.4%) and the hypoactive subtype (4.7%). The factors most associated with delirium were age (adjusted RR = 1.07; 95% CI, 1.05-1.09), the presence of four or more comorbidities (adjusted RR = 2.04; 95% CI, 1.31-3.20), and being a patient in the ICU (adjusted RR = 2.02; 95% CI, 1.22-3.35). CONCLUSIONS: The incidence of delirium is heterogeneous in the different departments of the university hospital. The highest incidence occurred in patients that were admitted to the GU. The mixed subtype was the most frequent one, and the main associated factors were age, the presence of four or more comorbidities, and being an ICU patient.

RESUMEN

resumen Introducción: Poco se conoce acerca de la incidencia del delirio en pacientes hospitalizados en diferentes servicios de hospitales universitarios en Latinoamérica y de los subtipos que se presentan. Objetivo: Determinar la incidencia del delirio, la frecuencia de los subtipos motores y los factores asociados en pacientes hospitalizados en diferentes servicios de un hospital uni versitario en Bogotá, Colombia. Métodos: Se dio seguimiento a una cohorte de pacientes mayores de 18 arios hospitalizados en los servicios de Medicina Interna, Geriatría, Cuidado Intensivo, Cirugía General y Orto pedia de un hospital universitario entre enero y junio de 2018. Para identificar la presencia de delirio, se utilizó la escala CAM (Confusion Assessment Method) y la CAM-ICU si el paciente presentaba disminución de las capacidades de comunicación. El subtipo de delirio se carac terizó utilizando la escala RASS (Richmond Agitation and Sedation Scale). Los pacientes fueron valorados el día de ingreso y luego cada 2 días hasta su alta hospitalaria. Se derivó a los pacientes en quienes se identificó delirio para tratamiento especializado interdisciplinario intrainstitucional. Resultados: Se evaluó a 531 pacientes que ingresaron durante ese periodo a los servicios mencionados. La incidencia global del delirio fue del 12% (IC95%, 0,3-14,8). En orden des cendiente, el 31,8% de los pacientes hospitalizados en el servicio de Geriatría, el 15,6% en Cuidado Intensivo, el 8,7% en Medicina Interna, el 5,1% en Ortopedia y el 3,9% en Cirugía. El subtipo motor más frecuente fue el mixto (60,9%), seguido por el normoactivo (34,4%) y el hipoactivo (4,7%). Los factores asociados con la incidencia del delirio fueron la edad (RR ajustada = 1,07; IC95%, 1,05-1,09), la presencia de 4 o más comorbilidades (RR ajustada = 2,04; IC95%, 1,31-3,20) y la hospitalización en Cuidado Intensivo (RR ajustada = 2,02; IC95%, 1,22 3,35). Conclusiones: La incidencia del delirio es heterogénea en los diferentes servicios del hospital universitario. La mayor incidencia se presentó en pacientes ingresados en el servicio de Geriatría; el subtipo más frecuente fue el mixto y los principales factores asociados fueron la edad, la presencia de 4 o más comorbilidades y la hospitalización en Cuidado Intensivo.

RESUMEN

RESUMEN La pandemia por el nuevo coronavirus denominado SARS-CoV-2 plantea retos sin precedentes en la atención de la salud. Entre ellos se cuenta el aumento en los casos de delirium. La enfermedad grave por SARS-CoV-2, COVID-19, tiene vulnerabilidades comunes con el delirium y produce alteraciones en órganos como el pulmón o el cerebro, entre otros, que tienen potencial para precipitar el trastorno mental; de hecho, este puede ser la primera manifestación de la infección, antes de la fiebre, el malestar general, la tos o las alteraciones respiratorias. Está ampliamente sustentado que el delirium incrementa la morbilidad y la mortalidad de quienes lo padecen durante una hospitalización, por lo que se debe buscar activamente para realizar las intervenciones pertinentes. Ante la ausencia de evidencia sobre el abordaje del delirium en el contexto de la COVID-19, se elaboró este consenso sobre tres aspectos fundamentales: diagnóstico, tratamiento no farmacológico y tratamiento farmacológico, en pacientes ingresados en el hospital general. El documento contiene recomendaciones sobre uso sistemático de herramientas diagnósticas, cuándo hospitalizar al paciente con delirium, la aplicación de acciones no farmacológicas dentro de las restricciones que impone la COVID-19 y la utilización de antipsicóticos teniendo en cuenta los efectos secundarios más relevantes y las interacciones farmacológicas.

ABSTRACT The pandemic caused by the new coronavirus named SARS-CoV-2 poses unprecedented challenges in the health care. Among them is the increase in cases of delirium. The severe SARS-CoV-2 disease, COVID-19, has common vulnerabilities with delirium and produces alterations in organs such as the lungs or the brain, among others, which have the potential to trigger the mental disorder. In fact, delirium may be the first manifestation of the infection, before fever, general malaise, cough or respiratory disturbances. It is widely supported that delirium increases the morbidity and mortality in those who suffer from it during hospitalization, so it should be actively sought to carry out the relevant interventions. In the absence of evidence on the approach to delirium in the context of COVID-19, this consensus was developed on three fundamental aspects: diagnosis, non-pharmacological treatment and pharmacological treatment, in patients admitted to the general hospital. The document contains recommendations on the systematic use of diagnostic tools, when to hospitalize the patient with delirium, the application of non-pharmacological actions within the restrictions imposed by COVID-19, and the use of antipsychotics, taking into account the most relevant side effects and pharmacological interactions.

RESUMEN

RESUMEN Objetivo: describir las prácticas farmacológicas y no farmacológicas para el delirium, realizadas por residentes de psiquiatría y psiquiatras en Colombia. Métodos: encuesta anónima basada en el consenso de expertos del Comité de Psiquiatría de Enlace de la Asociación Colombiana de Psiquiatría y en la literatura. Enviada por correo electrónico a los adscritos a la asociación. Resultados: Participaron 101 clínicos. Las medidas preventivas no farmacológicas como psi-coeducación, corrección de problemas sensoriales o higiene del sueno son realizadas por el 70% o más. Solo cerca de uno de cada 10 hace parte de algún programa multicomponente preventivo institucional. La prescripción preventiva de fármacos fue menor del 20%. Respecto al tratamiento no farmacológico, más del 75% hace corrección de dificultades sensoriales, control de estímulos y reorientación. Nadie indicó que en su centro la atención esté organizada para potenciar el tratamiento no farmacológico. El 17,8% no usa fármacos en el tratamiento. Los que los usan prefieren haloperidol o quetiapina, especialmente en casos hiperactivos o mixtos. Conclusiones: Las prácticas de los encuestados coinciden con las de otros expertos en el mundo. En general, las acciones no farmacológicas son iniciativas individuales, lo que evidencia la necesidad de que las instituciones colombianas de salud se comprometan con el abordaje del delirium, especialmente cuando su prevalencia y consecuencias son indicadores de calidad en la atención.

ABSTRACT Objective: To describe pharmacological and non-pharmacological practices for delirium, carried out by psychiatry residents and psychiatrists in Colombia. Methods: An anonymous survey was conducted based on the consensus of experts of the Liaison Psychiatry Committee of the Asociación Colombiana de Psiquiatría [Colombian Psychiatric Association] and on the literature review. It was sent by email to the association members. Results: 101 clinicians participated. Non-pharmacological preventive measures such as psychoeducation, correction of sensory problems or sleep hygiene are performed by 70% or more. Only about 1 in 10 participants are part of an institutional multi-component prevention programme. The preventive prescription of drugs was less than 20%. Regarding non-pharmacological treatment, more than 75% recommend correction of sensory difficulties, control of stimuli and reorientation. None of the participants indicated that the care at their centres is organised to enhance non-pharmacological treatment. 17.8% do not use medication in the treatment of delirium. Those who use it prefer haloperidol or quetiapine, particularly in hyperactive or mixed motor subtypes. Conclusions: The practices of the respondents coincide with those of other experts around the world. In general, non-pharmacological actions are individual initiatives, which demonstrates the need in Colombian health institutions to commit to addressing delirium, in particular when its prevalence and consequences are indicators of quality of care.

RESUMEN

RESUMEN Las distonías son trastornos del movimiento caracterizados por contracciones musculares sostenidas que producen movimientos repetitivos de torsión o posturas anormales. Pueden clasificarse según la etiología como primarias (formas idiopáticas y genéticas) o secundarias. La presentación asociada con episodios generalizados, intensos y con exacerbación de contracturas musculares intensas que suelen ser refractarias a la farmacoterapia tradicional se conoce como status distónico o tormenta distónica. Se presenta el caso de un paciente de 33 arios, con antecedente de sordera congénita, trastorno por consumo de sustancias psicoactivas y tratamiento psicofarmacológico con antipsicóticos, que presentó un cuadro distónico grave que evolucionó a un status distónico.

ABSTRACT Dystonia is a movement disorder characterised by sustained muscle contractions that produce repetitive twisting movements or abnormal postures. It can be classified according to the aetiology as primary (idiopathic and genetic forms), or secondary. The presentation associated with generalised, intense episodes and with exacerbation of severe muscle contractures and usually refractory to traditional pharmacotherapy is known as dystonic status or dystonic storm. In the present article, a case is presented of a 33-year-old patient with a history of congenital deafness, stimulant use disorder and on psychopharmacological treatment with antipsychotics, who presented with a severe dystonic reaction that evolved to a status dystonicus.

RESUMEN

Objetivos: Ayudar al clínico en la toma de decisiones sobre las modalidades de atención disponibles para el adulto con diagnóstico de esquizofrenia. Determinar cuáles son las modalidades de atención que se asocian a mejores desenlaces en personas adultas con diagnóstico de esquizofrenia. Método: Se elaboró una guía de práctica clínica bajo los lineamientos de la Guía Metodológica del Ministerio de Salud y Protección Social para identificar, sintetizar, evaluar la evidencia y formular recomendaciones respecto al manejo y seguimiento de los pacientes adultos con diagnóstico de esquizofrenia. Se adoptó y actualizó la evidencia de la guía NICE 82, que contestaba la pregunta acá planteada. Se presentó la evidencia y su graduación al grupo desarrollador de la guía (GDG) para la formulación de las recomendaciones siguiendo la metodología propuesta por el abordaje GRADE. Resultados: Se revisaron siete metaanálisis para la formulación de las recomendaciones de esta pregunta. Los pacientes que estuvieron en la modalidad de tratamiento asertivo comunitario presentaron un menor riesgo de nuevas hospitalizaciones. Para la modalidad de atención de manejo intensivo de caso se encontraron resultados concluyentes que favorecen a la intervención para rehospitalizaciones a mediano plazo, funcionamiento social y satisfacción con los servicios. Los equipos de resolución de crisis favorecen a esta frente al cuidado estándar en los desenlaces de rehospitalizaciones, funcionamiento social y satisfacción con el servicio. Conclusión: La utilización de diferentes modalidades de atención conlleva a la necesidad de ofrecer un abordaje integral a los pacientes. La evidencia muestra beneficios para la mayoría de los desenlaces estudiados sin encontrarse riesgos para la integridad o la salud de los pacientes. En esta evaluación se recomienda utilizar modalidades de prestación de servicios de salud que tengan una base comunitaria y que cuenten con un grupo multidisciplinario. No se recomienda usar la modalidad hospital día en la fase aguda de la esquizofrenia en adultos.

Objectives: To assist the clinician in making decisions about the types of care available for adults with schizophrenia. To determine which are the modalities of treatment associated with better outcomes in adults with schizophrenia. Methods: A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. The evidence of NICE guide 82 was adopted and updated. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. Results: Patients who were in Assertive community treatment had a lower risk of new hospitalizations. For the intensive case management, the results favored this intervention in the outcomes: medium term readmissions, social functioning and satisfaction with services. The crisis resolution teamswas associated with better outcomes on outcomes of readmissions, social functioning and service satisfaction in comparison with standard care. Conclusion: The use of different modalities of care leads to the need of a comprehensive approach to patients to reduce the overall disability associated with the disease. Evidence shows overall benefit for most outcomes studied without encountering hazards for health of patients. This evaluation is recommended to use the professional ways of providing health services that are community-based and have a multidisciplinary group. It is not recommended the modality "day hospital" during the acute phase of schizophrenia in adults.

RESUMEN

Introducción: Motivados por un caso clínico, en el presente reporte se comentan algunos aspectos relacionados con la amputación genital autoinfligida en términos de descripciones, aspectos epidemiológicos y clínicos. Método: Reporte de caso. Se describe un caso clínico de autoamputación genital; posteriormente se realiza una discusión al respecto, utilizando para ello la información disponible en la literatura científica. Se trata de un hombre de 32 años sin antecedente de trastorno mental que se amputa el pene con un objeto cortante luego de una discusión con su pareja por infidelidad. Resultados: Varias características denotan factores de riesgo para la automutilación genital, como los trastornos de identidad de género, rechazo a los genitales masculinos, sentimientos de culpa relacionados con la actividad sexual y antecedentes de intentos autolesivos previos. Los diagnósticos más frecuentes son las esquizofrenias y los trastornos afectivos, seguidos de trastornos inducidos por sustancias psicoactivas. Conclusión: La autoamputación genital no es una situación frecuente y se ha tendido a su subregistro; sin embargo, teniendo en cuenta la alta asociación con psicopatología y con recurrencia que se reporta en la literatura mundial, es necesario realizar un adecuado estudio y seguimiento en los pacientes que presentan esta conducta...

Introduction: Motivated by a clinic case, this report introduces some issues related with genital self-amputation in terms of descriptions, epidemiological and clinical issues. Methodology: Case report describing a clinic case of genital self-amputation. The description is followed by a discussion based on the information available in the scientific literature. A man, 32 years old, with no history of mental disorder, who amputates his penis with a cutting object after quarreling with his mate for infidelity reasons. Results: Several characteristics imply risk factors for genital self-mutilation, such as gender identity disorders, rejection to male genitals, guilt feelings related to sexual activity and a history of previous self-injuries. More common diagnoses include schizophrenia and affective disorders followed by disorders induced by psychoactive substances. Conclusion: Genital self-amputation is not a frequent situation and has been under-recorded; however, bearing in mind the high association with psychopathology and recurrence reported in worldwide literature, it is necessary to carry out a proper study and following up of patients exhibiting this conduct...

RESUMEN

Introducción: La insuficiencia renal crónica (IRC) es un problema de salud pública. La patología psiquiátrica en esta población puede repercutir en la calidad de vida relacionada con la salud (CVRS). La mayoría de estudios sobre CVRS y los síntomas depresivos y/o ansiosos no son latinoamericanos. Objetivo: determinar la CVRS y la prevalencia de depresión y ansiedad en pacientes de seis unidades renales de Bogotá, Colombia. Método: Estudio multicéntrico, descriptivo, de corte trasversal, en adultos de ambos sexos con IRC y que reciben tres sesiones semanales de hemodiálisis. Se les administraron las fichas de datos sociodemográficos SF-36 y HADS. Resultados: 174 sujetos participaron en el estudio, de los cuales 163 fueron considerados para el análisis final (entre 19 y 86 años de edad; 57,06% hombres). La CVRS física general fue de 38,70 (DE 8,62) y la CVRS mental general, de 44,73 (DE 10,39). Se sospecha de depresión en 15,95%, de problema clínico en 5,52%, de ansiedad en 16,46%. Se presenta un problema clínico en 13,29%. Conclusiones: Este estudio usa la muestra latinoamericana más grande de la que se tenga conocimiento. La CVRS es comparable con la hallada en otras poblaciones, excepto por el rango anormalmente bajo de desempeño físico. Al situar el punto de corte de la HADS para depresión en 9, se podría aumentar su sensibilidad aumentando la prevalencia de depresión. Conforme desciende la CVRS mental general, es mayor la presencia de depresión; a medida que desciende la CVRS total, es más probable la existencia de un cuadro ansioso...

Introduction: End-Stage Renal Disease (ESRD) is a major health problem. Psychiatric comorbidity could affect Health-Related Quality of Life (HRQL). Most studies analyzing HRQL as well as depressive and/or anxiety symptoms have been undertaken in non-Latin-American populations. Objective: To determine HRQL and the prevalence of depression and anxiety in patients assisting to six hemodialysis (HD) units in Bogotá, Colombia. Method: Multicentric, descriptive, transversal study in patients over 18 of both genders with ESRD, who were receiving HD three times per week. A sociodemographic questionnaire, the SF-36, and the HADS were administered. Results: 174 subjects participated in the study, but only 163 were considered for the final analysis (ages ranged from 19 to 86 years old; 57.06 were males). The physical HRQL was 38.70 (SD 8.62) and the mental HRQL was 44.73 (SD 10.39). Depression was suspected in 15.95% and a clinical problem was present in 5.52% of the cases. Anxiety was suspected in 16.46% of the subjects and a clinical problem existed in 13.29% of them. Conclusions: This is the largest Latin-American sample known of to date. HRQL was comparable to other populations except for the Role-Physical, which is the lowest described in the literature. With the intention of increasing sensibility, the cut point of 9 might be the more appropriate when screening for depression with the HADS. As mental HRQL decreases, the presence of depression increases; as total HRQL decreases, the possibility of finding anxiety increases...

RESUMEN

Introducción: Desde hace más de 50 años el litio se ha utilizado en psiquiatría y su eficacia se ha establecido para el tratamiento de los trastornos afectivos. Su uso se limita en ocasiones por su estrecho rango terapéutico y su perfi l de efectos colaterales. Desde los años ochenta, las secuelas de la neurotoxicidad por sales de litio han llamado la atención y fueron descritas por Adityanjee, bajo el acrónimo SILENT (del inglés Syndrome of Irreversible Lithium Effectuated Neurotoxicity). Objetivos: Discutir los aspectos clínicos relacionados con la neurotoxicidad secundaria a sales de litio e incrementar el conocimiento sobre este tema en la comunidad médica. Método: Revisión narrativa de la literatura médica. Resultados y conclusiones: Más del 90% de las personas en tratamiento con litio experimentan algún tipo de efecto colateral. Dentro de las secuelas neurológicas persistentes se destaca la disfunción cerebelosa, aunque existen otras presentaciones atípicas como alteraciones oculomotoras y neuropatía periférica. Es fundamental que el clínico reconozca estos síntomas y que se desarrollen estrategias, como el uso de criterios estrictos para la implementación de tratamiento con esta sustancia, la prevención de la intoxicación aguda y el seguimiento riguroso durante el mantenimiento...

Introduction: Lithium has been a medication used in psychiatry for more than 50 years and its efficacy has been established in the treatment of mood disorders. The use of lithium is limited due to its narrow therapeutic range and toxicity. Its persistent neurological secondary effects caught clinical attention in the 80s and were described by Adityanjee under the acronym SILENT (Syndrome of Lithium-effectuated Neurotoxicity). Objective: To discuss the clinical aspects of lithium toxicity and to increase physicians’ awareness of this subject. Method: Narrative review based on the available literature. Results and Conclusion: More than 90% of individuals treated with lithium experience some side effect. Neurological sequelae include persistent cerebellar dysfunction, oculomotor abnormalities and peripheral neuropathy. It is important for physicians to recognize these symptoms and it becomes necessary to develop strategies like the use of stricter criteria for starting lithium to prevent acute intoxication, and the rigorous monitoring of serum levels during treatment...

RESUMEN

El puerperio es uno de los períodos de mayor riesgo en la presentación de trastornos del estado de ánimo. Cerca de 85% de las mujeres presentan algún tipo de alteración del estado de ánimo durante el posparto. Algunas mujeres experimentan síntomas transitorios y leves. Sin embargo, entre 8 y 25% de las mujeres manifiestan algún tipo de trastorno incapacitante y persistente. En este último grupo, permanecen sin diagnosticar el 50% de los casos. Varios reportes recientes sobre infanticidio por parte de mujeres con enfermedad psiquiátrica en el posparto, señalan la importancia de diagnosticar y tratar estos trastornos. Su detección precoz es limitada por cuanto ni se busca atención, ni se realiza tamizaje de rutina. El presente documento resume la situación de estos trastornos con base en el análisis de la literatura disponible.

RESUMEN

El trastorno de la Tourette (TT) es un complejo síndrome neuropsiquiátrico que se caracteriza por la presencia de tics motores y vocales, síntomas que inician antes de los 18 años de edad. Este trastorno provoca un deterioro significativo en importantes áreas del funcionamiento del individuo, y tiene un patrón de cronicidad bien establecido, alternándose periodos de remisión y exacerbación de los síntomas. El TT presenta una importante comorbilidad con otros trastornos del eje I, como el trastorno obsesivo-compulsivo, trastornos por déficit de atención con hiperactividad y trastornos del aprendizaje. El presente artículo pretende revisar los aspectos epidemiológicos, etiológicos y fenomenológicos de la enfermedad así como las perspectivas terapéuticas. [Oviedo GF. Trastorno de la Tourette. MedUNAB 2004; 7:125-29]

De la Tourette ́s disorder. Tourette Syndrome (TS) is a complex neuropsychiatric disorder in which tic symptoms emerge prior to age of 18 and have, at least, a minimum duration of 12 months. This disorder produces distress and impairs normal functioning; it has a well-known chronic-waxing and waning course. TS has several comorbid conditions like obsessive-compulsive disorder, attention deficit-hyperactivity disorder, and learning disorders, among others. This article will review the epidemiologic, etiologic and phenomeno-logical concepts of the disease and its therapeutic perspectives
