Testing an Adapted Auditory Verbal Learning Test Paradigm for fMRI to Lateralize Verbal Memory in Patients with Epilepsy.

BACKGROUND AND PURPOSE: fMRI is a noninvasive tool for predicting postsurgical deficits in candidates with pharmacoresistant temporal lobe epilepsy. We aimed to test an adapted paradigm of the Rey Auditory Verbal Learning Test to evaluate differences in memory laterality indexes between patients and healthy controls and its association with neuropsychological scores. MATERIALS AND METHODS: We performed a prospective study of 50 patients with temporal lobe epilepsy and 22 healthy controls. Participants underwent a block design language and memory fMRI. Laterality indexes and the hippocampal anterior-posterior index were calculated. Language and memory lateralization was organized into typical and atypical on the basis of laterality indexes. A neuropsychological assessment was performed with a median time from fMRI of 8 months and was compared with fMRI performance. RESULTS: We studied 40 patients with left temporal lobe epilepsy and 10 with right temporal lobe epilepsy. Typical language occurred in 65.3% of patients and 90.9% of healthy controls (P = .04). The memory fMRI laterality index was obtained in all healthy controls and 92% of patients. The verbal memory laterality index was bilateral (24.3%) more frequently than the language laterality index (7.69%) in patients with left temporal lobe epilepsy. Atypical verbal memory was greater in patients with left temporal lobe epilepsy (56.8%) than in healthy controls (36.4%), and the proportion of bilateral laterality indexes (53.3%) was larger than right laterality indexes (46.7%). Atypical verbal memory might be associated with higher cognitive scores in patients. No relevant differences were seen in the hippocampal anterior-posterior index according to memory impairment. CONCLUSIONS: The adapted Rey Auditory Verbal Learning Test paradigm fMRI might support verbal memory lateralization. Temporal lobe epilepsy laterality influences hippocampal memory laterality indexes. Left temporal lobe epilepsy has shown a higher proportion of atypical verbal memory compared with language, potentially to memory functional reorganization.

COVID-19 inpatients with psychiatric disorders: Real-world clinical recommendations from an expert team in consultation-liaison psychiatry.

BACKGROUND: The management of coronavirus disease 2019 (COVID-19) in patients with comorbid psychiatric disorders poses several challenges, especially regarding drug interactions. METHODS: We report three representative case-scenarios on patients with psychiatric disorders and COVID-19 to provide a practical approach based on the existing literature and the clinical experience of an expert team in consultation-liaison psychiatry. CASE-CENTERED RECOMMENDATIONS: Psychopharmacological ongoing treatments should be prioritized and most doses should be reduced 25-50% of original dose if the patient receives lopinavir/ritonavir, with some exceptions including quetiapine, asenapine, olanzapine, sertraline, lamotrigine, bupropion, and methadone. If the psychopharmacological usual doses are in the low-to-median range levels, a dose change during COVID-19 drugs co-administration is not recommended, but only ECG and clinical monitoring of adverse effects and drug levels if required. Furthermore, when introducing a psychopharmacological drug, dose titration should be progressive, with ECG monitoring if cardiotoxic interactions are present. (A) In agitated delirium, olanzapine is recommended as first-line antipsychotic and quetiapine should be avoided. (B) In severe mental illness (SMI), essential treatments should be maintained. (C) In non-SMI with depressive/anxiety symptoms, psychological support should be provided and symptoms identified and treated. LIMITATIONS: Most recommendations on pharmacological interactions provide only a limited qualitative approach and quantitative recommendations are lacking. CONCLUSIONS: Patients with psychiatric disorders and COVID-19 should be managed on a personalized basis considering several clinical criteria and, should not be excluded from receiving COVID-19 treatments. Risks of pharmacological interaction are not absolute and should be contextualized, and most psychopharmacological treatments should include an ECG with special attention to QTc interval.

Inflammatory Bowel Disease and Eating Disorders: A systematized review of comorbidity.

OBJECTIVE: Research has shown that there is an association between Inflammatory Bowel Disease, anxiety and mood disorders, however little is known about their association with Eating Disorders. In this paper we will present a case of a young female with a comorbid diagnosis of Inflammatory Bowel Disease and Eating Disorder, and then discuss the results from a systematic review of the literature, describing published cases of patients with the same condition. METHODS: A systematized review of the literature was conducted according to MOOSE guidelines. A computerized literature search of MEDLINE, PsycINFO and EMBASE, and a manual search through reference lists of selected original articles were performed to identify all published case-reports, case series and studies of Inflammatory Bowel Disease and Eating Disorders. RESULTS: Fourteen articles were included, encompassing 219 cases, including ours. The vast majority were females ranging from 10 to 44years old. Anorexia Nervosa (n=156) and Crohn's Disease (n=129) was the most frequent combination (n=90) reported in the literature. These cases present a poor prognosis because of corticoid refusal, medication abandon and/or deliberate exacerbation of IBD symptoms, in the context of trying to lose weight. CONCLUSION: Recent evidence suggests there is a possible association between Inflammatory Bowel Disease and Eating Disorders, although the mechanisms involved in its ethiopathogenesis are still unknown. To be aware of this association is important because a delayed diagnosis of this comorbidity may lead to worse prognosis. Further research and a multidisciplinary approach could facilitate earlier diagnosis and provide therapeutic interventions.

Risk factors associated with xerostomia in haemodialysis patients.

BACKGROUND: To determine the prevalence of xerostomia and hyposalivation in Haemodialysis (HD) patients, to clarify risk factors, assess patient's quality of life, and to establish a possible correlation among interdialytic weight gain (IDWG) and xerostomia. MATERIAL AND METHODS: This study was performed on a group of 50 HD patients. Data were collected using a questionnaire containing demographic and clinical variables, a visual analogue scale (VAS) for xerostomia, IDWG, and an oral health impact profile questionnaire (OHIP-14). Unstimulated whole saliva (UWS) and stimulated whole saliva (SWS) were collected. RESULTS: A total of 28 HD patients (56%) suffered xerostomia. Dry mouth was associated with hypertension (OR, 5.24; 95% CI, 1.11-24.89) and benzodiazepine consumption (OR, 5.96; 95% CI, 1.05-33.99). The mean xerostomia VAS and OHIP-14 scores were 31.74±14.88 and 24.38±11.98, respectively. No significant correlation was observed between IDWG% and VAS and OHIP total score. Nonetheless, a positive correlation between VAS level of thirst and IDWG% was found (r=0.48 p=0.0001). UWS and SWS means (determined in 30 patients) were 0.16±0.17 and 1.12±0.64, respectively. Decreased values of UWS and SWS were reported in 53.33% and 36.66% of HD patients. CONCLUSIONS: Xerostomia in HD has a multifactorial aetiology due to accumulative risks as advanced age, systemic disorders, drugs, fluid intake restriction, and salivary parenchymal fibrosis and atrophy. Therefore, it is important to detect possible xerostomia risk factors to treat correctly dry mouth in HD patients and avoid systemic complications.

A New Quantitative Approach to Assessing Noncompliance With Medical Recommendations in Heart Transplant Recipients.

BACKGROUND: Failure of compliance with medical regimen is one of the major risk factors associated with morbidity and mortality in heart transplant (HT) recipients. Nevertheless, to date, there is no specific, gold-standard, comprehensive set of tools for assessing compliance in these patients. OBJECTIVE: The objective of the present study was to develop a specific instrument for the assessment of noncompliance with medical recommendations in HT recipients. METHODS: This prospective observational study used a nonprobability sampling method, which was performed from January 2006 to December 2012. All of the patients met clinical criteria for being included on the waiting list for a HT. We designed a scale for measuring the compliance degree at 12 months after heart transplantation. This scale included the most important aspects of the medical regimen, using nine discrete quantitative variables. The total score was described as the patient's Noncompliance Factor (NCF). The results were analysed by mean, ranks, and percentages. RESULTS: The sample was constituted of 61 participants who underwent surgical HT intervention and completed the 12-month follow-up assessment. The overall incidence of noncompliance was around 30% and only 43.1% of the recipients had an acceptable degree of compliance. CONCLUSIONS: The overall incidence of noncompliance in HT recipients is high and this can generate worse clinical outcomes. Evaluation by specific screening instruments like the one proposed in the present study can be useful for a systematic detection of this phenomenon.

PET/MRI and PET/MRI/SISCOM coregistration in the presurgical evaluation of refractory focal epilepsy.

We aimed to investigate the usefulness of coregistration of positron emission tomography (PET) and magnetic resonance imaging (MRI) findings (PET/MRI) and of coregistration of PET/MRI with subtraction ictal single-photon emission computed tomography (SPECT) coregistered to MRI (SISCOM) (PET/MRI/SISCOM) in localizing the potential epileptogenic zone in patients with drug-resistant epilepsy. We prospectively included 35 consecutive patients with refractory focal epilepsy whose presurgical evaluation included a PET study. Separately acquired PET and structural MRI images were coregistered for each patient. When possible, ictal SPECT and SISCOM were obtained and coregistered with PET/MRI. The potential location of the epileptogenic zone determined by neuroimaging was compared with the seizure onset zone determined by long-term video-EEG monitoring and with invasive EEG studies in patients who were implanted. Structural MRI showed no lesions in 15 patients. In these patients, PET/MRI coregistration showed a hypometabolic area in 12 (80%) patients that was concordant with seizure onset zone on EEG in 9. In 7 patients without MRI lesions, PET/MRI detected a hypometabolism that was undetected on PET alone. SISCOM, obtained in 25 patients, showed an area of hyperperfusion concordant with the seizure onset zone on EEG in 7 (58%) of the 12 of these patients who had normal MRI findings. SISCOM hyperperfusion was less extensive than PET hypometabolism. A total of 19 patients underwent surgery; 11 of these underwent invasive-EEG monitoring and the seizure onset zone was concordant with PET/MRI in all cases. PET/MRI/SISCOM coregistration, performed in 4 of these patients, was concordant in 3 (75%). After epilepsy surgery, 13 (68%) patients are seizure-free after a mean follow-up of 4.5 years. PET/MRI and PET/MRI/SISCOM coregistration are useful for determining the potential epileptogenic zone and thus for planning invasive EEG studies and surgery more precisely, especially in patients without lesions on MRI.

PICOGEN: experiencia de 5 años de un programa de asesoramiento genético en demencia / PICOGEN: Five years experience with a genetic counselling program for dementia

Introducción: Describimos la experiencia del Programa de Información y Consejo Genético para demencias familiares (PICOGEN) en sus 5 a˜nos de funcionamiento. Métodos: Todos los sujetos fueron asesorados por un neurólogo que seleccionó los candidatos a estudio genético según la historia familiar y el diagnóstico (enfermedad de Alzheimer [EA], degeneración lobular frontotemporal [DLFT] o enfermedad priónica). Los sujetos asintomáticos que decidieron conocer su estatus genético siguieron un protocolo estructurado de evaluación antes y después de la realización del test genético. Resultados: Ochenta y siete pacientes de 72 familias fueron candidatos a estudio genético, 20 de 72 familias presentaban historia familiar autosómica dominante de inicio precoz (HADp). En 22 se detectó una mutación patogénica (8 PSEN1, 1 PSEN2, 1 APP, 4 MAPT, 8 PRNP), 5 no descritas previamente. Todos los casos con mutación, excepto uno PSEN1 (12,5%) y 4 PRNP (50%) presentaban HADp. En 3 casos con HADp (15%) no se encontró ninguna mutación. 24 de 54 sujetos asintomáticos de familias con mutación conocida decidieron realizarse el estudio presintomático, 10 resultaron portadores. En el seguimiento de los sujetos que realizaron el estudio predictivo no se observó ninguna complicación psiquiátrica mayor. Conclusiones: En nuestra serie la HADp resultó un criterio sensible para la detección de mutaciones patogénicas en EA y DLFT, pero no en enfermedades priónicas. Un 15% de los casos HADp no presentaron alteraciones genéticas causales en estudios diagnósticos convencionales. El 43% de los sujetos en riesgo que recibieron asesoramiento genético individual realizaron el estudio presintomático. El estudio presintomático resultó seguro en este contexto (AU)

Introduction: We describe the 5 year experience of a genetic counselling program for familial dementias (the PICOGEN program). Methods: The neurologist selected the candidates for genetic testing in the screening visit based on family history and phenotype (Alzheimer disease-AD, frontotemporal lobar degeneration-FTLD, or prion disease). Asymptomatic subjects who decided to know their genetic status were evaluated within a structured protocol by the psychiatrist and psychologist prior to entering the program and followed up afterwards. Results: A total of 87 patients from 72 families were candidates for the genetic study, 20 of the 72 families had a family history of autosomal dominant early-onset dementia (ADEOD). A pathogenic mutation was found in 22 patients (8 PSEN1, 1 PSEN2, 1 APP, 4 MAPT, 8 PRNP), 5 of which had not been previously described. All positive cases, except for 1 PSEN1 (12.5%) and 4 PRNP (50%) showed ADEOD. In 3 ADEOD cases (15%) no pathogenic mutation was found. After individual genetic counselling, 24/54 asymptomatic subjects at risk decided to have the presymptomatic study, of whom 10 (42%) were carriers of the pathogenic mutation. In the follow up, no major psychiatric complication was observed. Conclusions: In our series, family history of ADEOD was a sensitive criterion for the detection of pathogenic mutations in AD and FTLD but not in prion diseases. No genetic anomalies were detected in 15% of the ADEOD cases using conventional diagnostic procedures, and 43% of presymptomatic subjects at risk who received individual genetic counselling decided to have the study. The pre-symptomatic diagnosis proved to be safe under these conditions (AU)

Total serum cholesterol levels and suicide attempts in child and adolescent psychiatric inpatients.

Associations between cholesterol and suicidal behavior in adolescent patients have not been explored in depth. In this study, 66 patients consecutively admitted to a psychiatric inpatient unit following attempted suicide were compared with a control group of 54 patients with no history of suicide attempts. The age range of the sample was from 8 to 18 years old. Cholesterol levels were significantly lower in attempted suicide patients than in controls (p < 0.02), supporting the hypothesis that lower cholesterol levels might be associated with suicidal behavior in patients with similar acute phase of their disorder.

Study on the efficacy and tolerability of amisulpride in medical/surgical inpatients with delirium admitted to a general hospital.

PURPOSE: To evaluate the efficacy and safety of amisulpride in medical inpatients who present with delirium. METHOD: Open label prospective study with 7-day follow-up. Forty hospital inpatients with delirium were recruited, seven of whom died and two of whom refused medication. The average dose of amisulpride for delirium treatment was 200-300 mg/day. Daily assessments were performed with Delirium Rating Scale (DRS), Positive Subscale of the Positive and Negative Syndrome Scale (PANSS-P), Mini Mental State Examination (MMSE), Neurological Subscale of the UKU side effect rating scale. Variance analysis was performed through repeated measurements, with the general linear model with paired comparisons and Bonferroni correction for each measured variable. RESULTS: Patients showed significant improvement on the DRS from the first day of treatment DRS = 17.55 until day 7 DRS = 7.26 (F = 92.485; p < 0.001), psychotic symptoms improved from first day PANSS-P = 18.26 to last day PANSS-P = 9.35 (F = 144.83; p < 0.001). Cognitive status showed a significant improvement from day 2 MMSE = 18.71 until day 7 MMSE = 24.06 (F = 96.56; p < 0.001), and the neurological subscale of the UKU side effect rating scale showed a significant improvement the last day with respect to baseline pretreatment level (F = 7.539; p = 0.01). CONCLUSIONS: These results suggest a good response to amisulpride in the acute phase of delirium, although further randomized controlled studies must be performed.

La hemisferectomía funcional también es eficaz en pacientes adultoscon epilepsia catastrófica / Successful functional hemispherectomy in adult patients with refractory epilepsy

Introducción. La hemisferectomía es una técnica quirúrgica empleada para tratar epilepsias farmaco resistentes en el contexto de síndromes hemisféricos difusos. La mayoría de las series de pacientes hemisferectomizados incluyen preferentemente pacientes en edad pediátrica. Métodos. Presentamos nuestra serie de cuatro pacientes adultos sometidos a hemisferectomía funcional para el tratamiento de su epilepsia refractaria tras realizarse una evaluación prequirúrgica completa. En tres pacientes la epilepsia era secundaria a un infarto dela arteria cerebral media y en uno a una encefalitis de Rasmussen. Resultados. Tras la cirugía tres pacientes permanecieron libres de crisis a lo largo del período de seguimiento (13-26 meses) y en el cuarto se consiguió una reducción >75% en su frecuencia de crisis. En todos los pacientes hubo una mejoría en su calidad de vida. Las complicaciones precoces tras la cirugía fueron una crisis tónico clónica aislada en un paciente y un estatus epiléptico precoz probablemente secundario a fiebre y meropenem que dismunuye el umbral convulsivo. El único déficit neurológico permanente que se produjo fue una hemianopsia en un paciente. Conclusión. La hemisferectomía funcional debe considerarse una opción quirúrgica en pacientes con epilepsia refractaria secundaria a lesiones hemisféricas extensas y que estén afectos previamente de hemiparesias graves (AU)

Introduction. Functional hemispherectomy is a surgical technique used to treat refractory epilepsies in the setting of extensive unilateral hemispheric lesions. Most series of hemispherectomies include mainly pediatric patients. Methods. We report our series of four adult patients that have undergone functional hemispherectomy for their refractory epilepsy. Each one had a complete presurgical evaluation including video EEG, neuropsychological testing and anatomical and functional neuroimaging. In three of them, the epilepsy was secondary to a middle cerebral artery infarction. One patient had Rasmussen encephalitis. Results. After surgery, three patents have become completely seizure free (follow up 13-26 months). The fourth patient has had more than 75% reduction in seizure frequency. All of them have had significant improvement in their quality of life. Early complications included an isolated tonic-clonic generalized seizure(one patient), and status epilepticus in another patients related to infection and use of meropenem. Only one patient has presented hemianopia as a permanent neurological deficit after surgery. Conclusions. Functional hemispherectomy is a good surgical option in the setting of large unilateral hemispheric lesions causing hemiparesis and intractable seizures, even in adult patients (AU)

Parry Romberg syndrome and linear scleroderma in coup de sabre mimicking Rasmussen encephalitis.

We present one patient with Parry Romberg syndrome and another with linear scleroderma in coup de sabre, with focal neurologic deficits and intractable seizures arising from the hemisphere ipsilateral to the cutaneous lesion. Brain MRI showed progressive hemispheric atrophy. Pathology after functional hemispherectomy showed chronic inflammatory features suggestive of Rasmussen encephalitis.

Complex motor behaviors in temporal lobe epilepsy.

Complex motor behaviors differing from typical automatisms were found in 12 of 502 patients with temporal lobe epilepsy. Movements involved proximal limb segments (6) or body axis (6) and were often preceded by auras and followed by automatisms. Seven of 12 patients are seizure free after surgery. The other 5 patients declined surgery.

[Psychiatric disease in patients with psychogenic non-epileptic seizures referred from an epilepsy unit in a general hospital]. / Patología psiquiátrica en pacientes con crisis no epilépticas psicógenas derivados a una unidad de epilepsia en un hospital general.

INTRODUCTION: We evaluate psychiatric disease associated with psychogenic non-epileptic seizures (PNES) and study the role played by previous traumatic experiences, dissociative episodes and personality disorders. METHOD: After diagnosing PNES in our epilepsy unit, we obtained a sample of 46 patients and carried out a structured psychiatric interview (SCID) following DSM-III-R criteria. We looked for previous dissociative episodes and prepared a questionnaire for traumatic experiences and basic clinical data. RESULTS: The most frequent psychiatric disorders were depression, anxiety and somatoform disorders. Personality disorders were found in 16 patients (34.78%), dissociative episodes in 17 (36.95%), and previous traumatic experiences in 14 (30.43%). No statistically significant differences were found in regards to PNES, with respect to presence or absence of previous traumatic experiences, dissociative episodes, and personality disorders. CONCLUSIONS: As in previous studies, our research project confirms the co-existence of PNES with other mental disorders, and although we do find a higher frequency of seizures, the role played by traumatic experiences and dissociative disorders in CNEP remains unclear.

Patología psiquiátrica en pacientes con crisis no epilépticas psicógenas derivados a una unidad de epilepsia en un hospital general / Psychiatric disease in patients with psychogenic non-epileptic seizures referred from an epilepsy unit in a general hospital

Introducción. Se evalúa la patología psiquiátrica que acompaña a las crisis no epilépticas psicógenas (CNEP) y se estudia el papel que desempeñan en ellas las experiencias traumáticas previas, los episodios disociativos y los trastornos de la personalidad. Método. Después del diagnóstico de CNEP en la Unidad de Epilepsia de nuestro centro se realizó en una muestra de 46 pacientes una entrevista psiquiátrica estructurada siguiendo criterios DSM-III-R (SCID). Se evaluó la existencia de episodios disociativos siguiendo criterios DSM-IV, y para las experiencias traumáticas y los datos clínicos de interés se confeccionó un cuestionario ad hoc. Resultados. Los trastornos psiquiátricos más frecuentes fueron los estados depresivos, los de ansiedad y los somatomorfos. Presentaban trastornos de la personalidad 16 pacientes (34,78 por ciento), fenómenos disociativos 17 pacientes (3695 9ó) y 14 pacientes (30,43 por ciento) antecedentes de experiencias traumáticas. No se observaron diferencias estadísticamente significativas en relación con las CNEP, respecto a la presencia o ausencia de experiencias traumáticas previas, trastornos disociativos o trastornos de la personalidad. Conclusiones. Como en trabajos previos, en nuestro estudio se confirma la existencia de una gran comorbilidad psiquiátrica en relación con las CNEP, y aunque asociadas a la presencia de un mayor número de crisis, el papel que tienen las experiencias traumáticas y los trastornos disociativos en relación con las CNEP permanece poco claro (AU)

A validation study of the hospital anxiety and depression scale (HADS) in a Spanish population.

The present study aims to validate the Spanish version of the Hospital Anxiety and Depression Scale (HADS) and to determine the use of this tool for screening mood and anxiety disorders. Psychometric properties of the HADS were assessed in different groups of general medical outpatients attending the Hospital Clínic in Barcelona (N=385), and psychiatric diagnoses were made using DSM-IV criteria. A two-factor solution corresponding to the original two subscales of the HADS was found. The Spanish version of the HADS had good internal consistency and external validity, with favorable sensitivity and specificity in identifying cases of psychiatric disorder as defined by the Structured Clinical Interview for DSM-IV (SCID-I). The psychometric properties of the HADS and its brevity make it useful for screening for psychiatric disorders in the medically ill.

Citalopram versus nortriptyline in late-life depression: a 12-week randomized single-blind study.

OBJECTIVE: The aim of this single-blind study was to examine the efficacy and tolerability of citalopram compared to nortriptyline in moderate to severe major depressive patients aged 60 years or over. METHOD: In- and out-patients (N=58) with unipolar major depression were randomized to 12-week flexible dose treatment with nortriptyline or citalopram. RESULTS: No significant differences between the number of drop-outs in either group were observed, but the autonomic side-effects were significantly higher for nortriptyline than for citalopram. A significantly higher remission rate to nortriptyline than to citalopram was demonstrated, particularly if severe patients (endogenous or psychotic patients) were assessed. CONCLUSION: The remission rate to a therapeutic plasma level of nortriptyline appears to be higher than the remission rate to a standard dose of citalopram in a group of elderly major depressed patients, especially those with endogenous or psychotic features. On the other hand, citalopram appears to be better tolerated.

Genetic variation in the 5-HT5A receptor gene in patients with bipolar disorder and major depression.

In the present study, genetic variation of the 5-HT5A receptor was analyzed in patients affected by affective disorders and healthy controls. The sample consisted of 181 patients with major depression, 88 patients with bipolar affective disorder (BP) and 157 unrelated controls (C), all of Spanish origin. Two polymorphisms (-19G/C and 12A/T) in the 5-HT5A receptor gene were analyzed by polymerase chain reaction amplification and subsequent enzyme digestion. No genotype, allele or haplotype differences were found when we compared patients and controls. When clinical variables were considered as possible tools for detecting genetic heterogeneity, no differences were found. Our results suggest that the polymorphisms analyzed in the 5-HT5A receptor gene do not play a major role in the pathogenesis of affective disorders.
