Tratamiento de la esquizofrenia en México: recomendaciones de un panel de expertos.

La esquizofrenia es una enfermedad compleja que actualmente no tiene cura. Existen, sin embargo, numerosas terapias que, solas o en combinación, son eficaces para tratar los síntomas de la enfermedad y mantenerla bajo control. La elección del tratamiento debe ser siempre individualizada, y basarse en la presentación clínica de la enfermedad, el estado general del paciente y la eficacia del fármaco, si bien hay que considerar también el costo y el acceso a servicios y al fármaco, que en México tiene algunas limitaciones. Un panel de 12 expertos mexicanos se reunió de forma virtual para revisar los últimos datos publicados y establecer unas recomendaciones de tratamiento en México, basadas en la evidencia, que garanticen una atención médica integral, homogénea, eficiente y con calidad.Schizophrenia is a complex illness that currently has no cure.

Abstract Schizophrenia is a complex illness that currently has no cure. There are, however, numerous therapies that, alone or in combination, are effective in treating the symptoms of the disease and keeping it under control. The choice of treatment must always be individualized, and based on the clinical presentation of the disease, the general condition of the patient and the efficacy of the drug, although the cost and access to services and to the drug must also be considered, as in Mexico it has some limitations. A panel of 12 Mexican experts met virtually to review the latest published data and establish evidence-based treatment recommendations in Mexico that guarantee comprehensive, homogeneous, efficient, and quality medical care.

Neurocirugía estereotáctica ablativa para trastorno neuroagresivo irreductible en pediátricos / Ablative stereotactic neurosurgery for irreducible neuroaggressive disorder in pediatric patients

Introducción y objetivos: El trastorno neuroagresivo irreductible (TNI) es una entidad bien descrita asociada con comportamiento impulsivo y agresivo. Es un dilema tanto para el tratamiento farmacológico como para el no farmacológico en la psiquiatría moderna, implicando un riesgo individual y social importante. A pesar de los avances en la terapia estereotáctica dirigida para TNI persiste una ausencia de información cuando se compara la eficacia de los diferentes blancos anatómicos validados. En el presente trabajo se describen los resultados quirúrgicos de los pacientes con TNI tratados con cirugía estereotáctica ablativa, con enfoque en los criterios de selección y métodos utilizados en nuestra institución. El objetivo es analizar la eficacia y seguridad de los diferentes blancos estereotácticos más utilizados para agresividad irreductible en niños. Materiales y métodos: Seleccionamos a 8 pacientes pediátricos con TNI bajo un estricto protocolo. Se les realizó electroencefalograma, videoelectroencefalograma y resonancia magnética previo a la cirugía. El síntoma neuroagresivo irreductible fue tratado con cirugía estereotáctica hacia los blancos cerebrales más descritos para agresividad, y posteriormente evaluado mediante la Overt Agressive Scale en el prequirúrgico y a los 6 meses de seguimiento, usando el test de Wilcoxon para el análisis estadístico. Resultados y conclusiones: La edad promedio de los pacientes fue de 13 años y 2 meses, 7 de los 8 pacientes incluidos tenían discapacidad intelectual, un paciente tenía secuelas neurológicas por síndrome de Dandy Walker y 7 pacientes no tenían alteraciones anatómicas preoperatorias. Después de la cirugía los pacientes mostraron mejoría en la escala Overt Agressive Scale con un promedio de 39,29% (p=0,0156), lo cual se encuentra dentro del rango descrito para TNI en adultos. Los resultados más satisfactorios tuvieron en común la inclusión del complejo nuclear amigdalino dentro de los blancos quirúrgicos. No hubo muertes ni secuelas permanentes atribuibles al procedimiento. La presente serie es la más grande descrita en la literatura hasta el momento para pacientes pediátricos con TNI tratados con ablación estereotáctica

Introduction and objectives: The irreducible neuroaggressive disorder (IND) is a well-described entity known to be associated with impulsive and aggressive behavior. While various studies have assessed available pharmacological and non-pharmacological treatment regimens, patients with IND continue to pose a major threat to themselves and society. While targeted stereotactic therapy for IND has gained traction in recent years, there is a paucity of information describing comparative effectiveness of different validated anatomic regions. In this paper, we discuss the surgical results for patients with IND following targeted lesional therapy with a special focus on selection criteria and operative methods. The objective is to analyze the efficacy and safety of the different described targets for this disorder in pediatric patients. Materials and methods: Eight pediatric patients met strict criteria for IND and were enrolled in this study. Electroencephalography (EEG), video electroencephalography (VEEG) and magnetic resonance imaging (MRI) were performed in all patients prior to surgery. Irreducible neuroagressive symptom was approached by lesional therapy based on most described targets for this disorder and assessed by The Overt Agressive Scale (OAS) pre-operatively and 6 months following surgery, using Wilcoxon test for statistical analysis. Results and conclusions: The average patient age was 13 years 2 months. 7 of the 8 patients enrolled had intellectual disabilities, 1 patient suffered neurologic sequelae referable to Dandy Walker syndrome and 7 patients had no preoperative anatomical alterations. Following surgery, patients with IND noted improvement in their OAS. On average, the OAS improved by 39.29% (P=.0156), a figure similar in comparison to studies assessing treatment of IND in adult patients. The most satisfactory results were achieved in patients whose ablative therapy involved the Amygdala in their targets. There were no deaths or permanent neurological deficits attributable to procedure. To the author's knowledge, this is the largest series described in the literature for pediatric patients with IND treated with lesional stereotactic therapy

Cambios en el perfil funcional de pacientes con patología psiquiátrica resistente sometidos a neurocirugía funcional estereotáctica / Changes in the functional profile of patients with resistant psychiatric disorders subjected to stereotactic functional neurosurgery / Mudanças no perfil funcional de pacientes con patologia psiquiátrica resistente submetidos a neurocirurgia funcional estereotáxica

Con el objetivo de evaluar los resultados de la Neurocirugía Funcional Estereotáctica (NFE) sobre el perfil funcional de los pacientes diagnosticados con Patología Psiquiátrica Resistente (PPR), se realizó un diseño pre/post tratamiento. 13 pacientes fueron evaluados ( = 31 ± 8 años): siete mujeres diagnosticadas con algún Trastorno de la Conducta Alimentaria Resistente (TCAR); tres mujeres diagnosticadas con Trastornos Resistentes Obsesivo Compulsivo y Depresivo (TOC y DR) y tres pacientes (dos mujeres y un hombre) diagnosticados con Depresión Resistente (DR). A estos pacientes se les aplicó la Escala de funcionamiento del paciente Eje K, la cual consta de siete subescalas, y una Escala de Evaluación de la Actividad Global (EAG) antes del tratamiento y después de éste (seis meses posteriores a la NFE). Todos los grupos diagnósticos y el total de los pacientes evaluados presentaron cambios clínicos positivos; sin embargo, sólo el grupo de TCAR mostró importantes cambios clínicos de mejoría en el perfil de funcionamiento, siendo esta diferencia estadísticamente significativa (pre Md = 56; post Md = 84; z= - 2.36, p <0.05). Con la evidencia obtenida se observó que la NFE representa una opción terapéutica emergente efectiva orientada a disminuir el sufrimiento de los pacientes con PPR, así como a mejorar el nivel de funcionamiento global y por ende su calidad de vida. Todos los pacientes del estudio presentaban una condición de resistencia a tratamientos convencionales indicados, la cual había sido documentada por un equipo interdisciplinario experto.

In order to evaluate the results of the Stereotactic Functional Neurosurgery (SFN) on the functional profile of patients diagnosed with Resistant Psychiatric Pathology (RPP), a pre / post treatment design was performed. Thirteen patients were assessed ( = 31 ± 8 years): seven women diagnosed with some type of Resistant Eating Disorder (RED); three women diagnosed with Resistant Obsessive Compulsive Disorder and Resistant Depression (TOC and RD), and three patients (two women and one man) diagnosed with Resistant Depression (RD). The Patient's Functioning Scale, axis K, consisting of seven subscales, and the Assessment of Global Activity Scale (AGAS) were applied before and after treatment (6 months after FSN). All diagnostic groups and all the patients assessed showed positive clinical changes. However, only the RED group showed important clinical improvement in the performance profile with a statistically significant difference (pre Md = 56, Md = 84 post , z = - 2.36, p <0.05). With the evidence obtained it was noted that SFN represents an effective therapeutic option aimed at reducing the suffering of patients with RPP and improve their overall level of functioning and therefore their quality of life. All patients in the study had a condition indicating resistance to conventional treatments which had been documented by an expert multidisciplinary team.

Psicocirugía en un paciente con trastorno obsesivo compulsivo resistente / Psychosurgery in a patient with refractory obsessive-compulsive disorder

El término psicocirugía fue introducido por primera vez por Egaz Moniz en 1937 para los procedimientos ablativos o resectivos del lóbulo frontal para disminuir síntomas psiquiátricos. La psicocirugía es un tratamiento disponible actualmente en varios centros mundiales, como tratamiento definitivo en pacientes bien seleccionados para enfermedades como el trastorno obsesivo-compulsivo resistente (TOC-R) y la agresividad resistente (AR) al tratamiento. En México no existen comités multidisciplinarios para el tratamiento de estas enfermedades psiquiátricas, ya que este tipo de pacientes tiene períodos de estancias hospitalarias prolongados e incapacidad laboral y personal, ésta es una alternativa no convencional que ha brindado la oportunidad de reincorporar a este tipo de pacientes y llevar una mejor observancia del tratamiento, se sabe que los centros más destacados en este ámbito están en Inglaterra, Estados Unidos y Chile. El presente artículo es un reporte de un caso en el que se demuestra la efectividad del procedimiento para disminuir los síntomas obsesivo y compulsivo resistentes, y al mismo tiempo corroborar que las funciones mentales superiores no están afectadas

The term psychosurgery was first used by Egaz Moniz in 1937 to describe ablative or resective procedures in the frontal lobe to reduce psychiatric symptoms. Psychosurgery is currently available in various centers throughout the world as the definitive treatment in selected patients with disorders such as refractory obsessive-compulsive syndrome and refractory aggression. In Mexico, multidisciplinary committees for the treatment of these psychiatric disorders are lacking since this type of patient undergoes long periods of hospitalization, as well as occupational and personal disability. Psychosurgery is an unconventional alternative that offers the possibility of reintegrating this type of patient and of achieving greater treatment compliance. The most important centers for psychosurgery are found in England, the USA and Chile. The present article reports a case that demonstrates the effectiveness of psychosurgery in reducing refractory obsessive-compulsive symptoms and corroborates that higher mental functions are left intact
