Hepatoxicity induced by clozapine: Case report and brief review.

INTRODUCTION: Antipsychotics are drugs that can produce transient elevations of hepatic enzymes. Clozapine is an atypical antipsychotic used in treatment-resistant schizophrenia and there is evidence that it can produce elevations of hepatic transaminases, expression of liver damage in a hepatocellular pattern. METHODS: Case report and non-systematic review of the relevant literature. CASE PRESENTATION: A 39-year-old woman with a diagnosis of paranoid schizophrenia attended the emergency department of a general hospital for nausea, vomiting and jaundice that appeared after the initiation of clozapine. There was no clinical improvement during hospitalisation, and death occurred after 44 days. LITERATURE REVIEW: Clozapine can increase the liver enzyme levels transiently and asymptomatically; however, there are clinical criteria that recommend the withdrawal of the antipsychotic. CONCLUSIONS: This is the third case reported in the literature of a fatal outcome of clozapine-induced hepatotoxicity.

Hepatotoxicidad inducida por clozapina: reporte de caso y revisión breve de la literatura

Introducción: Los antipsicóticos son medicamentos que pueden producir elevaciones transitorias de las enzimas hepáticas. La clozapina es un antipsicótico atípico usado en el tratamiento de la esquizofrenia refractaria a los antipsicóticos convencionales y existe evidencia que puede producir elevaciones de las transaminasas hepáticas, expresión de dafño hepático con patrón hepatocelular. Métodos: Reporte de caso y revisión no sistemática de la literatura relevante. Presentación del caso: Una mujer de 39 años con diagnóstico de esquizofrenia paranoide acudió a un servicio de urgencias de un hospital general por náuseas, vómitos e ictericia que apareció tras el inicio de clozapina. No hubo mejoría clínica de la paciente durante la hospitalización, que falleció a los 44 días de su ingreso. Revisión de la literatura: La clozapina puede elevar las cifras de función hepática de manera transitoria y asintomática. Hay criterios clínicos para recomendar la suspensión de este antipsicótico. Conclusiones: Este caso es el tercero en la literatura que registra un desenlace fatal tras un cuadro de hepatotoxicidad inducido por clozapina. © 2021 Asociación Colombiana de Psiquiatría.

Depresión psicótica secundaria a hipertiroidismo y desenlace letal por tormenta tirotóxica: a propósito de un caso / Psychotic depression secondary to hyperthyroidism and lethal outcome by thyrotoxic storm: case report

RESUMEN El rol de exceso y déficit de hormona tiroidea en la patogenia de trastornos del ánimo se ha registrado desde hace casi dos siglos. Las patologías tiroideas, las más numerosas dentro de las enfermedades endocrinas, se asocian causalmente a patología psiquiátrica en un importante porcentaje de casos. Específicamente, el hipertiroidismo produce múltiples manifestaciones psicopatológicas de tipo ansioso y depresivo, episodios de manía e, infrecuentemente, psicosis. Aunque el influjo del eje tiroideo sobre las vías neurales de noradrenalina, dopamina, y serotonina juega un rol neurobiológico fundamental en estos fenómenos, existen todavía múltiples mecanismos subyacentes por dilucidar. Dada la necesidad de un diagnóstico diferencial amplio y abarcador entre patologías psiquiátricas primarias y secundarias, reportamos el caso de una paciente de 52 años con depresión psicótica, en la que el diagnóstico tardío de hipertiroidismo acarreó consecuencias penosas y letales. La valoración clínica y laboratorial de la función tiroidea, debe ser parte de la evaluación psiquiátrica de cualquier persona con trastornos afectivos y ansiosos.

SUMMARY The role of excess and deficit of thyroid hormone in the pathogenesis of mood disorders has been recorded for almost two centuries. Thyroid pathologies, the most numerous among endocrine diseases, are causally associated with psychiatric pathology in a significant percentage of cases. Specifically, hyperthyroidism produces multiple psychopathological manifestations of anxious and depressive type, manic episodes and, infrequently, psychosis. Although the influence of the thyroid axis on the neural pathways of norepinephrine, dopamine, and serotonin plays a fundamental neurobiological role in these phenomena, there are still multiple underlying mechanisms to be elucidated. Given the need for a broad and comprehensive differential diagnosis between primary and secondary psychiatric pathologies, we report the case of a 52-year-old patient with psychotic depression in whom the late diagnosis of hyperthyroidism had painful and lethal consequences. Clinical and laboratory-based evaluations of thyroid function should be part of the psychiatric evaluation of any person with affective and anxiety disorders.

Estudio comparativo de la capacidad denominativa y la memoria episódica de los pacientes con demencia degenerativa / Comparative Study of the Word Capacity and Episodic Memory of Patients with Degenerative Dementia

RESUMEN Introducción: Aunque la ausencia de deterioro de la memoria se consideró entre los criterios diagnósticos para diferenciar la enfermedad de Alzheimer (EA) de la demencia frontotemporal variante conductual (DFTvC), la evidencia actual, en aumento, sería la un importante porcentaje de casos de DFTvC con déficits de la memoria episódica. El presente estudio se diseñó con el fin de comparar el perfil de desempeño de la capacidad denominativa y de la memoria episódica de los pacientes con EA y DFTvC. Métodos: Estudio transversal y analítico con grupo de control (n = 32). Se incluyó a 42 sujetos con probable EA y 22 con probable DFTvC, todos mayores de 60 años. Se utilizaron instrumentos del Uniform Data Set validados en español: Multilingual Naming Test (MINT), historia de Craft-21 y Figura compleja de Benson, entre otros. Resultados: Se observó un mayor promedio de edad entre los pacientes con EA. La capacidad denominativa fue mucho menor en los pacientes con DFTvC que en aquellos con EA, medida según el MINT y el coeficiente de denominación sustantivos/verbos. Todos los pacientes con DFTvC, el 73,81% de aquellos con EAy solo el 31,25% de los controles no lograron reconocer la Figura compleja de Benson. Todas las diferencias fueron estadísticamente significativas (p< 0,001). Resultados: Este estudio confirma el perfil amnésico de los pacientes con EA y revela la disminución de la capacidad denominativa de los pacientes con DFTvC, un área del lenguaje que se afecta típica y tempranamente con las funciones ejecutivas, según recientes hallazgos. Conclusiones: Los pacientes con EA rinden peor en las tareas de memoria episódica verbal y visual, mientras que los pacientes con DFTvC rinden peor en tareas de denominación. Estos hallazgos abren la posibilidad de explorar los mecanismos de participación prefrontal en la memoria episódica, típicamente atribuida al hipocampo.

ABSTRACT Introduction: Although the absence of memory impairment was considered among the Alzheimer's disease diagnostic criteria to differentiate Alzheimer's disease (AD) from Behavioural Variant of Frontotemporal dementia Frontotemporal Dementia (bvFTD), current and growingevidence indicates that a significant Neuropsychological assessment percentage of cases of bvFTD present with episodic memory deficits. In order to compare Memory the performance profile of the naming capacity and episodic memory in patients with AD and bvFTD the present study was designed. Methods: Cross-sectional and analytical study with control group (32 people). The study included 42 people with probable AD and 22 with probable bvFTD, all over 60 years old. Uniform Data Set instruments validated in Spanish were used: Multilingual Naming Test (MINT), Craft-21 history and Benson's complex figure, among others. Results: A higher average age was observed among the patients with AD. The naming capacity was much lower in patients with bvFTD compared to patients with AD, measured according to the MINT and the nouns/verbs naming coefficient. All patients with bvFTD, 73.81% of those with AD and only 31.25% of the control group failed to recognise Benson's complex figure. All differences were statistically significant (p < 0.001). Results:This study confirms the amnesic profile of patients with AD and reveals the decrease in naming capacity in patients with bvFTD, an area of language that is typically affected early on with executive functions, according to recent findings. Conclusions: Patients with AD perform worse in verbal and visual episodic memory tasks, while patients with bvFTD perform worse in naming tasks. These findings open the possibility of exploring the mechanisms of prefrontal participation in episodic memory, typically attributed to the hippocampus.

Social Cognition and Behavioral Assessments Improve the Diagnosis of Behavioral Variant of Frontotemporal Dementia in Older Peruvians With Low Educational Levels.

Background: The behavioral variant of frontotemporal dementia (bvFTD), characterized by early behavioral abnormalities and late memory impairment, is a neurodegenerative disorder with a detrimental impact on patients and their caregivers. bvFTD is often difficult to distinguish from other neurodegenerative diseases, such as Alzheimer's disease (AD), using brief cognitive tests. Combining brief socio-cognitive and behavioral evaluations with standard cognitive testing could better discriminate bvFTD from AD patients. We sought to evaluate the diagnostic accuracy of brief socio-cognitive tests that may differentiate bvFTD and AD patients with low educational levels. Methods: A prospective study was performed on 51 individuals over the age of 50 with low educational levels, with bvFTD or AD diagnosed using published criteria, and who were receiving neurological care at a multidisciplinary neurology clinic in Lima, Peru, between July 2017 and December 2020. All patients had a comprehensive neurological evaluation, including a full neurocognitive battery and brief tests of cognition (Addenbrooke's Cognitive Examination version III, ACE-III), social cognition (Mini-social Cognition and Emotional Assessment, Mini-SEA), and behavioral assessments (Frontal Behavioral Inventory, FBI; Interpersonal Reactivity Index-Emphatic Concern, IRI-EC; IRI-Perspective Taking, IRI-PT; and Self-Monitoring Scale-revised version, r-SMS). Receiver operating characteristic (ROC) analysis to calculate the area under the curve (AUC) was performed to compare the brief screening tests individually and combined to the gold standard of bvFTD and AD diagnoses. Results: The AD group was significantly older than the bvFTD group (p < 0.001). An analysis of the discriminatory ability of the ACE-III to distinguish between patients with AD and bvFTD (AUC = 0.85) and the INECO Frontal Screening (IFS; AUC = 0.78) shows that the former has greater discriminatory ability. Social and behavioral cognition tasks were able to appropriately discriminate bvFTD from AD. The Mini-SEA had high sensitivity and high moderate specificity (83%) for discriminating bvFTD from AD, which increased when combined with the brief screening tests ACE-III and IFS. The FBI was ideal with high sensitivity (83%), as well as the IRI-EC and IRI-PT that also were adequate for distinguishing bvFTD from AD. Conclusions: Our study supports the integration of socio-behavioral measures to the standard global cognitive and social cognition measures utilized for screening for bvFTD in a population with low levels of education.

Necrólisis epidérmica tóxica en una adolescente diagnosticada de trastorno bipolar II y tratada con lamotrigina / Toxic epidermal necrolysis in an adolescent with Bipolar Disorder II and treated with Lamotrigine

Resumen La necrólisis epidérmica tóxica es una enfermedad cutánea severa, la mayoría de las veces desencadenada como reacción adversa a medicamentos, con alta morbilidad y mortalidad. La lamotrigina, junto a otros medicamentos estabilizadores del ánimo, constituye la causa medicamentosa más frecuente de esta complicación, consistente en necrosis y esfacelo de la epidermis y mucosas en más del 30 % de la superficie corporal, con la consecuente pérdida de líquidos y electrolitos, respuesta inflamatoria sistémica, susceptibilidad a infecciones y hasta sepsis, además de posibles secuelas ominosas. En la actualidad, el diagnóstico de trastorno bipolar se hace con mayor frecuencia, incluyendo al grupo etario de niños y adolescentes, pero tal proceso diagnóstico se caracteriza por dificultades y controversias en mayor cuantía que otros diagnósticos psiquiátricos. Ello obliga a una meticulosa elucubración diagnóstica y selección farmacológica, con pleno conocimiento de las moléculas del arsenal medicamentoso para, en caso de prescripción de lamotrigina, establecer una escrupulosa psicoeducación al paciente y sus familiares además de un seguimiento estricto y cercano. A propósito del caso de una adolescente diagnosticada de trastorno bipolar II, que recibió lamotrigina durante un episodio depresivo pero con un esquema posológico inadecuado, y desarrolló necrólisis epidérmica tóxica, revisamos y comentamos la literatura correspondiente. Concluimos en que es preciso extremar las precauciones al decidir el uso de lamotrigina para minimizar el riesgo de este severo efecto adverso.

Toxic epidermal necrolysis is a severe skin disease, most often triggered as an adverse drug reaction, with high morbidity and mortality. Lamotrigine, together with other mood stabilizer drugs, constitutes the most frequent drug that causes this complication, which consists of necrosis and detachment of the epidermis and mucosa in more than 30% of the body surface, with the consequent loss of water and electrolytes, systemic inflammatory response, susceptibility to infections and even sepsis, in addition to other possible ominous sequelae. Currently, the diagnosis of bipolar disorder is made more frequently, including the age group of children and adolescents, but such a diagnostic process is characterized by difficulties and controversies to a greater extent than other psychiatric diagnoses. This requires meticulous diagnostic process and pharmacological selection, with full knowledge of the molecules in the drug arsenal so, in case of lamotrigine prescription, it should be established scrupulous psychoeducation to the patient and their family members, as well as strict and close follow-up. A propos of the case of an adolescent girl diagnosed with bipolar II disorder, who received lamotrigine during a depressive episode but with an inappropriate posology, and developed toxic epidermal necrolysis, we reviewed and commented on the corresponding literature. We conclude that extreme caution is necessary when deciding the use of lamotrigine to minimize the risk of this severe adverse effect.

Uso inapropiado de psicofármacos prescritos: diazepam intravenoso en la emergencia psiquiátrica / Inappropriate use of prescribed psychotropic drugs: Intravenous diazepam in the psychiatric emergency

RESUMEN Las benzodiacepinas (BZD) son medicamentos esenciales en el tratamiento de diferentes problemas de salud: en el Petitorio Nacional de Medicamentos de nuestro país figuran cinco de ellas autorizadas para administración oral o parenteral. Al inicio de su uso en la década de 1960, fueron prescritas de forma amplia e irrestricta; el desarrollo posterior de fenómenos de tolerancia y abstinencia desatados por su uso prolongado restringió enérgicamente su empleo, a veces por debajo de las reales necesidades clínicas. Aunque las BZD están incluidas en el grupo IV de sustancias controladas de la Agencia de Control de Drogas (DEA) de los Estados Unidos de América, se acepta que, en general, no son drogas primarias de abuso, y los fenómenos adictivos relacionados con su uso requieren factores adicionales de riesgo tales como comorbilidad con otras drogodependencias. Es necesario distinguir entre casos de "uso inapropiado" de las BZD y aquellos que presentan criterios de franca dependencia. De hecho, se han reportado pocos casos de uso inapropiado de BZD prescritas por vía parenteral. Se presenta y discute el de una mujer de 51 años que, por un tiempo prolongado, acudió a emergencia psiquiátrica debido a crisis de disforia y ansiedad (no de pánico), recibiendo en varias oportunidades inyecciones intravenosas de diazepam, al punto que empezó luego a acudir reiteradamente para exigir la medicación sin que fuera médicamente necesaria. Es conveniente, por lo tanto, que el profesional que prescriba BZD parenterales, lo haga cautelosamente a fin de prevenir un proceso adictivo que puede generar serias consecuencias.

SUMMARY Benzodiazepines (BZDs) are essential drugs used in the treatment of different health problems: Peru's National Drug Petitionary lists five of them allowed for oral or parenteral administration. At the beginning in the 1960s, BZDs were widely and unrestrictedly prescribed; the subsequent development of tolerance and withdrawal phenomena, triggered by their prolonged use, led to drastic prescription restrictions, sometimes below the real clinical needs. Although BZDs are included in the Drug Enforcement Administration (DEA) group IV of controlled substances, it is accepted that, in general, they are not primary drugs of abuse, and the development of addictive phenomena only occurs in the presence of comorbidity with other drug addictions. It is necessary to distinguish between the "inappropriate use" or "misuse" of the BZDs and those cases that meet criteria of full dependence. There are few reported cases of inappropriate use of BZD prescribed by parenteral route. The case reported here is one of a 51-years-old woman who, over the course of several years, went to a psychiatric emergency service due to crisis of dysphoria and anxiety (but not a panic attack), and received on several occasions, intravenous injections of diazepam, to the point that later she used to go repeatedly to demand such medication, without being medically necessary. It is, therefore, important for the prescribing professional to use parenteral BZDs cautiously and carefully, in order to prevent an addictive process that can generate serious consequences.

Covid-19 y cetoacidosis diabética erróneamente diagnosticadas como ansiedad primaria: Reporte de un caso acerca de causas médicas versus psiquiátricas de ansiedad / COVID-19 and diabetic ketoacidosis misdiagnosed as primary anxiety: A case report on medical versus psychiatric causes of anxiety

RESUMEN Los trastornos de ansiedad tienen gran importancia en la psiquiatría de urgencias, tanto por la frecuencia con la que se presentan, como por la relevancia de las enfermedades somáticas que pueden subyacer a un cuadro ansioso. Resulta imperativo determinar desde el abordaje diagnóstico inicial si los signos y síntomas de la ansiedad constituyen una plena respuesta a situaciones de estrés, son manifestaciones de una patología somática subyacente, o se pueden explicar como síntomas de un trastorno psiquiátrico primario específico. En el momento actual, la pandemia de COVID-19 -en la que el Perú ha llegado a tener la mayor tasa de mortalidad mundial-- desborda los servicios de salud con abigarrados cuadros en los que se combinan tanto los síntomas de la infección viral por sí misma, como los de reacciones ansiosas y respuestas al estrés. A propósito de un caso ilustrativo, en el que el proceso de tamizaje médico fue deficitario y se etiquetó al paciente como un caso primario de "ansiedad", con un desenlace lamentablemente ominoso, se revisa brevemente la literatura acerca del proceso de medical clearance (o descarte de condiciones médicas) y se reafirma concluyentemente la importancia de una consideración diagnóstica inicial abarcadora, no sesgada, y basada en criterios clínicos sólidamente elaborados y sustentados. Es evidente, por otro lado, que el psiquiatra requiere estar permanentemente actualizado sobre las formas de presentación psicopatológica asociadas a la sintomatología de COVID-19.

SUMMARY Anxiety disorders are of great importance in emergency psychiatry, both because of the frequency with which they occur, and because of the relevance of somatic diseases that can underlie an anxious condition. It is imperative to determine, from the initial diagnostic approach, whether the signs and symptoms of anxiety constitute either a response to stress, are manifestations of an underlying somatic pathology, or are explained as symptoms of a specific, primary psychiatric disorder. Currently, the COVID-19 pandemic --in which Peru has had the highest mortality rate in the world-is overwhelming the health services with complex and confusing pictures in which both the symptoms of the viral infection itself, as well as the of anxious reactions and stress responses are combined. On the basis of an illustrative case, in which the medical screening process was deficient and the patient was labeled as a primary case of "anxiety", with a regrettably ominous outcome, the literature about medical clearance is briefly reviewed, to categorically highlight the importance of a comprehensive and unbiased diagnostic consideration, based on well-developed and substantiated clinical criteria. On the other hand, the psychiatrist nowadays needs to be updated on the forms of psychopathological presentations associated with the symptoms of COVID-19.

Primera centuria de la presencia de Hideyo Noguchi en el Perú / First century of Hideyo Noguchi's presence in Peru

Resumen En este año 2020 se conmemora un siglo de la presencia física de Hideyo Noguchi en el Perú. Noguchi arribó en el marco de sus investigaciones científicas acerca de la fiebre amarilla que asolaba el norte de nuestra patria. Aquella época de epidemia e incuria, de penuria y descalabro de diversos órdenes en el tejido social, fue similar a la circunstancia que ahora nos toca vivir, y por ende hoy es necesario recordar la imagen inspiradora de este médico y prohombre, no exento de complejidades ni de errores en su naturaleza humana, pero dotado de profunda convicción, espíritu de sacrificio y entrega a la humanidad doliente a través de la ciencia. La centuria de la presencia física de Hideyo Noguchi en el Perú motiva el boceto de este perfil biográfico.

Summary This year, 2020, we commemorate the 100th Anniversary of the physical presence of Hideyo Noguchi in Peru. He arrived here a century ago in the context of his scientific research about the yellow fever that ravaged the northern area of our country. Such period, very similar to the time we live in nowadays, was a time of epidemic and neglect, of hardship and misfortune of various orders in the social fabric of our country. Therefore, today it is necessary to remember the inspiring image of this physician and great man, not without complexities or errors in his human nature, but endowed with deep convictions, spirit of sacrifice and dedication to the suffering humanity through science. The century of the physical presence of Hideyo Noguchi among us, motivates the sketch of this biographical profile.

Síndrome de Otelo secundario a tuberculoma cerebral: a propósito de un caso / Othello Syndrome Secondary to Cerebral Tuberculoma: A Case Report

RESUMEN Introducción: El síndrome de Otelo, epónimo del personaje de Shakespeare, es un término diagnóstico transnosológico que designa un cuadro caracterizado por delirios de infidelidad respecto a la pareja que, por consiguiente, puede acarrear actitudes celotípicas y conductas violentas hacia ella. En su forma pura, corresponde al trastorno delirante de infidelidad, pero también puede ser secundario a organicidad cerebral y a consumo de drogas. Métodos: Reporte de caso y revisión no sistemática de la literatura relevante. Presentación del caso: Varón de 26 arios con antecedente de consumo de drogas y víctima de maltrato infantil, 3 años antes había sufrido crisis convulsivas tónico-clónicas e hipertensión intracraneal, por lo que se sometió a una craneotomía, en la que se halló un tuberculoma cerebral frontal derecho. Tras un lapso, comenzó con delirios de infidelidad y conductas violentas hacia su pareja. Revisión de la literatura: Los celos delirantes se asocian, como otros delirios, a lesiones del lóbulo frontal derecho. Pese a la elevada y creciente prevalencia mundial de tuberculosis, no se han publicado casos de síndrome de Otelo secundario a tuberculoma cerebral. Conclusiones: El síndrome de Otelo, aunque no es la principal causa de violencia doméstica, puede asociarse con manifestaciones particularmente violentas y ser secundario a tuberculoma cerebral. Este es el primer caso de tal índole que se publica.

ABSTRACT Introduction: Othello syndrome, an eponym of Shakespeare's character, is a transnosological diagnostic term that designates a clinical picture characterised by the presence of delusions of infidelity with respect to a partner and that, consequently, can lead to typical jealousy attitudes and violent behaviour towards the partner. In its pure form, it corresponds to delusional disorder of infidelity, but it may also be secondary to brain organicity and drug use. Methods: Case report and non-systematic review of the relevant literature. Case presentation: A 26-year-old man, with a history of drug abuse and a victim of domestic violence as a child, presented with tonic-clonic seizures and intracranial hypertension three years ago, for which he underwent a craniotomy with the finding of a right frontal cerebral tuberculoma. After a lapse, he developed a clinical picture of delusions of infidelity regarding his partner and violent behaviour towards her. Literature review: Delusional jealousy is associated, like other delusions, with lesions of the right frontal lobe. Despite the high and growing prevalence of tuberculosis worldwide, there are no reported cases of Othello syndrome secondary to cerebral tuberculoma in the literature. Conclusion: Othello syndrome, although not the main cause of domestic violence, can be associated with particularly violent manifestations and be secondary to cerebral tuberculoma. This is the first published case of its kind.

A Propósito De Un Caso De Demencia Frontotemporal - Variante conductual, Con Síntomas Amnésicos E Imágenes Cerebrales Tipo Alzheimer / About a case of Frontotemporal Dementia - behavioral variant, with amnesic symptoms and Alzheimer type cerebral images: report of a case

Resumen La Demencia frontotemporal - variable conductual (DFT-vc), es una importante causa de discapacidad en adultos menores de 65 años. Se postula como una enfermedad neurológica con manifestaciones predominantemente psiquiátricas y, por tanto, constituye un frecuente diagnóstico diferencial ante patologías psiquiátricas de inicio no temprano. Aunque tradicionalmente se consideraba entre sus criterios diagnósticos a la ausencia de deterioro de la memoria -como en la Enfermedad de Alzheimer (EA)-, diversos estudios registran hasta un 15% de prevalencia de casos con franco deterioro mnésico, igualmente las neuroimágenes de uno y otro cuadro demencial pueden tener un traslape. Actualmente la presencia de "síndromes de fenocopia" -cuadros clínicos semejantes a DFT-vc pero sin deterioro cognitivo- y casos de EA con síntomas de desinhibición y conductuales, tornan más complejo el diagnóstico clínico y sugieren la insuficiencia de los criterios establecidos para el diagnóstico y la necesaria adopción de criterios paraclínicos. Con ese fin presentamos un caso ilustrativo de DFT-vc con deterioro de la memoria, y revisamos la bibliografía pertinente.

Frontotemporal dementia - behavioral variant (FTD-bv), is an important cause of disability in adults under 65 years of age. It is postulated as a neurological disease with predominantly psychiatric manifestations and, therefore, constitutes a frequent differential diagnosis in psychiatric pathologies of not early onset. Although traditionally the absence of memory impairment was considered among its diagnostic criteria - as opposed to Alzheimer'a disease (AD) -, several studies have found until 15% of prevalence of cases with frank mnemonic deterioration, as well as neuroimaging of one and the other can have overlap. Currently, the presence of "phenocopy syndromes" - clinical pictures similar to FTD-bv but without cognitive impairment- and cases of AD with disinhibition and behavioral symptoms, make the clinical diagnosis more complex and suggest the insufficiency of the established diagnostic criteria and the necessary adoption of paraclinical criteria. To this purpose, we present an illustrative case of FTD-bv with memory impairment and Alzheimer-like neuroimages, and we review the pertinent bibliography.

Anorexia nervosa con desenlace fatal: a propósito de un caso / Anorexia nervosa with fatal outcome: A case report

Resumen La Anorexia Nervosa (AN) es el trastorno psiquiátrico con mayor nivel de mortalidad directa y, a la vez, causa de múltiples y riesgosas complicaciones somáticas tales como: bradicardia, hipotensión ortostática, arritmias cardiacas, hipoglicemia, falla hepática, alteraciones hidroelectrolíticas y hormonales, osteopenia, dilatación gástrica y, finalmente, muerte súbita por diferentes causas. A pesar de su prevalencia relativamente baja, afecta a personas jóvenes con larga expectativa de vida. Su manejo, cuando llega a niveles de gravedad severa (IMC < 15), es complejo, pues requiere trabajo conjunto de psiquiatría y otras especialidades médicas y puede tener consecuencias ominosas. Se presenta y discute el caso de una paciente mujer de 19 años cuyo IMC llegó a 11 y que, lamentablemente, falleció mientras recibía atención hospitalaria. Se revisan las principales complicaciones médicas de la AN, remarcándose la necesidad de considerar los parámetros pertinentes para una atención hospitalaria oportuna que pueda evitar desenlaces fatales.

Summary Anorexia Nervosa (AN) is the psychiatric disorder with the highest direct mortality level and, at the same time, the cause of multiple and risky somatic complications such as bradycardia, orthostatic hypotension, cardiac arrhythmias, hypoglycemia, liver failure, hydro-electrolytic and hormonal disorders, osteopenia, gastric dilation and, finally, sudden death from different causes. Despite its relatively low prevalence, it affects young people with a long life expectancy. Its medical management, when reaching a high severity level (BMI <15), is complex as it requires joint work between psychiatry and other medical specialties, and can even have ominous consequences. The case of a 19-year-old woman whose BMI was around 11, and who unfortunately died while receiving hospital care, is discussed. The main complications of AN are reviewed, and the need to consider the relevant parameters for a timely hospital care are highlighted, in order to avoid fatal outcomes.

Comparative Study of the Word Capacity and Episodic Memory of Patients with Degenerative Dementia. / Estudio comparativo de la capacidad denominativa y la memoria episódica de los pacientes con demencia degenerativa.

INTRODUCTION: Although the absence of memory impairment was considered among the diagnostic criteria to differentiate Alzheimer's disease (AD) from Behavioural Variant of Frontotemporal Dementia (bvFTD), current and growing evidence indicates that a significant percentage of cases of bvFTD present with episodic memory deficits. In order to compare the performance profile of the naming capacity and episodic memory in patients with AD and bvFTD the present study was designed. METHODS: Cross-sectional and analytical study with control group (32 people). The study included 42 people with probable AD and 22 with probable bvFTD, all over 60 years old. Uniform Data Set instruments validated in Spanish were used: Multilingual Naming Test (MINT), Craft-21 history and Benson's complex figure, among others. RESULTS: A higher average age was observed among the patients with AD. The naming capacity was much lower in patients with bvFTD compared to patients with AD, measured according to the MINT and the nouns/verbs naming coefficient. All patients with bvFTD, 73.81% of those with AD and only 31.25% of the control group failed to recognise Benson's complex figure. All differences were statistically significant (p <0.001). RESULTS: This study confirms the amnesic profile of patients with AD and reveals the decrease in naming capacity in patients with bvFTD, an area of language that is typically affected early on with executive functions, according to recent findings. CONCLUSIONS: Patients with AD perform worse in verbal and visual episodic memory tasks, while patients with bvFTD perform worse in naming tasks. These findings open the possibility of exploring the mechanisms of prefrontal participation in episodic memory, typically attributed to the hippocampus.

Catatonía secundaria a edema cerebral / Catatonia secondary to cerebral oedema

Objetivo: La sospecha de causa médica subyacente debe dirigir el abordaje clínico y paraclínico ante un caso nuevo de catatonía, con ese fin presentamos un caso de etiología antes no reportada en la literatura. Caso clínico: Varón de 58 años, sin antecedentes médicos de importancia, con síndrome catatónico de una semana de evolución; las neuroimágenes mostraron imagen tumoral parietal izquierda con intenso edema circundante, sospechosa de granuloma tuberculoso. La resolución del edema, con uso de corticoides, llevó a la desaparición de la catatonía. Resultado: A diferencia de otros reportes, donde solamente la exéresis de la masa tumoral conllevaba la resolución de la catatonía, en el presente reporte el tratamiento del edema cerebral resolvió el cuadro catatónico. Conclusiones: Nuestro caso subraya la necesidad de detección temprana de la catatonía para su adecuado manejo, sintomático o causal. Hasta donde conocemos, no hay reportes previos de catatonía secundaria a edema cerebral

Objective: The suspicion of an underlying medical cause must guide to the clinical and paraclinical approach when faced with a new case of catatonia. For that purpose, a case is presented in which the aetiology has never been reported in the literature. Clinical case: A 58 year-old man, with no significant medical history, presenting with a catatonic syndrome of one week onset. Neuroimages showed a left parietal tumour with intense surrounding oedema, suspicious of tuberculous granuloma. The oedema was resolved with corticosteroid use, which led to the disappearance of the catatonia. Result: Contrary to other reports where the excision of the tumour mass was followed by the resolution of the catatonia, in this case the treatment of the cerebral oedema resolved the catatonia completely. Conclusion: The case presented highlights the need for the early detection of catatonia in order to be managed appropriately, either symptomatic or causal. As far as we know, there are no previous reports in the literature of catatonia secondary to cerebral oedema
