[Cryptogenic new-onset super-refractory status epilepticus following SARS-CoV-2 vaccination. A case report]. / Estado epiléptico superrefractario de nueva aparición criptógeno tras vacunación contra el SARS-CoV-2. A propósito de un caso.

INTRODUCTION: New-onset super-refractory status epilepticus (NOSRSE) is a neurological emergency characterised by the development of status epilepticus in a patient without epilepsy or any known prior neurological disease and with no clear structural, toxic or metabolic cause, which recurs after 24 hours of induced coma. The most common identifiable cause is inflammatory-autoimmune. Consequently, we present a case of NOSRSE related to SARS-CoV-2 vaccination as an opportunity to investigate the dysimmune origin of this pathology. CASE REPORT: We report the case of a 40-year-old male who presented at the emergency department with fever and headache with no clear source of infection. His personal history included bacterial meningitis in childhood without any sequelae and protein S deficiency without treatment at the time, as well as vaccination with ChAdOx1 nCoV-19 21 days earlier. He was initially diagnosed with a urinary tract infection and treated with cefuroxime. Two days later, he was taken back to the emergency department with confusional symptoms and tonic-clonic seizures. He did not respond to midazolam and finally required sedation and orotracheal intubation for refractory status epilepticus. While in hospital, he required a number of lines of antiepileptic drugs, ketamine, a ketogenic diet, immunotherapy and plasmapheresis in order to successfully limit NOSRSE. The aetiological study offered normal results for serology, antineuronal antibodies in serum and cerebrospinal fluid, transthoracic echocardiography, testicular ultrasound and computed tomographic angiography. Only the control MRI scan showed a diffuse and bilateral alteration of the right hemispheric cortex and thalamic pulvinar as the only finding. CONCLUSION: It is crucial to report suspected adverse reactions associated with SARS-CoV-2 vaccination, thereby allowing continued monitoring of the risk/benefit ratio of vaccination.

Validation of a short useful questionnaire in Spanish for the epidemiological screening of epilepsy in Spain. EPIBERIA Questionnaire.

INTRODUCTION: There is a major gap in knowledge about the epidemiology of epilepsy in Mediterranean countries. The EPIBERIA group was formed with the aim of promoting the conducting of epidemiological studies in this region in order to improve this situation. This paper deals with the validation of a brief questionnaire for screening patients with epilepsy in the general population. METHODS: We selected an English-language questionnaire previously validated by the Ottman group. It was translated, modified to suit the characteristics of the Spanish population, and administered to a sample of 200 patients (93 epileptics and 107 non-epileptic patient controls) sampled consecutively from 5 epilepsy units in different cities in Spain. Both groups were homogeneous in demographic variables and the control group was representative of the general population. RESULTS: We obtained a sensitivity of 100% and a specificity of 74.77% for the least rigorous correction model for the questionnaire, with a sensitivity of 94.62% and a specificity of 99.07% for the most stringent correction model. The PPV ranged from 7.48% for the first case to 69.49% in the second, assuming an epilepsy prevalence of 2%. CONCLUSIONS: The questionnaire EPIBERIA is a valid Spanish tool for epilepsy screening in the general population in Spain.

Longitudinal study of in-hospital consultations with neurology in a tertiary hospital. A health care activity on the increase.

OBJECTIVE: In-hospital consultation (IHC) is a service that some medical specialties provide to others with the aim of resolving complications in patients admitted to different hospital units. The aim of this study is to perform a descriptive analysis and longitudinal study of IHCs received in our department during the last 5 years. METHOD: A retrospective study was conducted on the IHCs made within the period 2005-2009. The data analysed were as follows: department of origin of the IHC, reason for consult, date, priority of care, definitive diagnosis, need for follow-up, need for transfer, and the demographic data of the patients. RESULTS: There were a total of 1458 IHCs in the period studied. The mean age of the patients was 58.2 ± 19.10 years, and 837 (57.6%) were males. The number of IHCs per year was: 2005: 263; 2006: 226; 2007: 239; 2007: 239, 2008: 329 and 2009: 401. The majority (86.8%) had normal priority, 8.5% high priority, and 4.7% were urgent. The Emergency Department (12%), Cardiology (10.9%), General Medicine (9.8%) and Psychiatry (8.9%) were the services with the highest demand. The most frequent reasons for consulting were loss of consciousness and epileptic seizures (24.6%), cerebral vascular disease (21.1%), and confusional states and cognitive impairment (13.4%). Over one third (36.8%) were resolved in the first consultation, and the remainder (63.8%) required follow up. Of all the cases assessed, 8.4% required transfer to Neurology. CONCLUSIONS: IHC is a complex activity that may not resolve all questions in a single visit. It involves a health care burden which is increasing annually. The increasing diagnostic complexity of the neurology, as well as the increasingly more specific treatments are the factors that lead to this higher demand.

[Based on the incidence of Creutzfeldt-Jakob disease in the Lanzarote healthcare area. Description of two definitive cases]. / A propósito de la incidencia de la enfermedad de Creutzfeldt-Jakob en el área de salud de Lanzarote. Descripción de dos casos definitivos.

We present two cases who have been diagnosed of definitive Creutzfeldt-Jakob disease in the health area of Lanzarote in the period January 2002 to January 2004. The two cases are presented with clinical description, complementary tests -- including electroencephalogram, 14-3-3 protein determination -- study of the prionic protein gene, and histopathologic findings. In this article, we try to show the importance of trying to reach a definitive diagnosis with the histopathologic study once there is clinical suspicion (a diagnosis that is probable or possible). In addition our cases show that communication between the clinical and the epidemiological coordinator of the regional community and the National Center of Epidemiology is very important. We refer to the clear growth in the incidence of the disease in the population of Lanzarote in the period above mentioned. Finally, we discuss whether this growth is or is not an isolated event.

[Creutzfeldt Jakob disease and hepatic encephalopathy: coexistence in the same patient]. / Enfermedad de Creutzfeldt Jakob y encefalopatía hepática: coexistencia en la misma paciente.

INTRODUCTION: Since detection of a series of cases of a new variant of Creutzfeldt Jakob disease (CJD) in the United Kingdom, prionic diseases are frequently mentioned by the media. The neurologists always consider them in daily clinical practice, although the incidence is relatively low (0.5-2 cases/1,000,000 inhabitants/year for CJD). In Spain, in recent years, we have seen an increased number of probable and possible cases, perhaps due to it always being included in the differential diagnosis, and to the greater use of diagnostic tests such as 14-3-3 protein in cerebrospinal fluid (CSF). There is also a reduction in the number of definite cases, probably due to the reticence to carrying out necropsies. In the differential diagnosis, one must remember structural, infectious, degenerative, toxic, vascular and metabolic alterations, including hepatic encephalopathy (HE). CLINICAL CASE: We report the case of a woman in whom CJD and EH co existed. This made diagnosis difficult. It was finally confirmed on necropsy.

[Callosotomy in the treatment of drug-resistant epilepsy]. / La callosotomía en el tratamiento de la epilepsia farmacorresistente.

At the present time corpus callosotomy is a valuable option in the management of some patients with drug-resistant epilepsy who are not candidates for resective procedures. The records of six patients who underwent callosotomy at 'Hospital Virgen de las Nieves' (Granada, Spain) in the past four years were retrospectively analyzed. The patients all had intractable primary or secondarily generalized seizures, were severely handicapped by its frequency and nature (especially with drop attacks and multiple injuries) and were not suitable for other surgical procedure. The results of surgery (five anterior callosotomies and one subtotal section) are described after an average follow-up period of 2.5 years. Overall, four patients achieved significant improvement (at least 50% reduction in seizure frequency, severity, or both, affecting quality of life), with a marked reduction (> 75%) in two of them. There was no clinical deterioration, significant surgical complication nor relevant additional long-term neuro-psychological deficit in any case. Previous studies have been reviewed mainly to find those prognostic factors associated with a better seizure outcome or with the occurrence of complications. The best results are obtained in those patients with drop attacks (including atonic seizures) as the most frequent and disabling seizure type. According to the type of epilepsy, patients with localization-related epilepsy (especially when symptomatic of a focal brain damage) and those with the Lennox-Gastaut syndrome are the most likely to benefit from the procedure. It is suggested that, in the first place, a two-thirds anterior callosotomy should be performed particularly with atonic seizure are the most frequent seizure type. We may proceed with completion of callosal division as a second stage in those patients in whom a significant improvement has not been observed. In severely retarded patients with multiple seizure types, one-stage complete section may be performed. The procedure is relatively safe, with a low incidence of morbidity and clinically significant long-term neuro-psychological deficits. Further larger clinical studies are necessary to elucidate many aspects which are still unresolved. More uniformity would be desirable in the evaluation of patients, surgical technique, follow-up and presentation of results.

[Non-giant cell temporal arteritis as a manifestation of Churg-Strauss syndrome. Presentation of a case and review of literature]. / Arteritis no de células gigantes de la temporal como manifestación clínica del síndrome de Churg-Strauss. Presentación de un caso y revisión de la literatura.

Most cases of temporal arteritis are of the giant cell variety, with cases involving other histologic patterns occurring rarely. There are only 4 descriptions in the literature of non giant cell temporal arteritis as a manifestation of Churg-Strauss syndrome. We report the case of a 74-year-old man with a history of bronchial asthma who presented with systemic symptoms and right temporal cephalea with diplopia, diffuse muscle pain and transient skin lesions on the extremities. The right temporal artery was enlarged and painful but pulsatile. Tests showed a high erythrocyte sedimentation rate and leukocytosis with relative and absolute eosinophilia. Biopsy of the temporal artery revealed polymorphic inflammatory infiltration throughout the vas, with numerous eosinophils and non giant cells, confirming a diagnosis of Churg-Strauss syndrome with extension to the temporal artery. Temporal arteritis should be considered a syndrome with variable substrate pathology; the possibility that it is a rare manifestation of systemic necrotizing vasculitis should not be ruled out.

[Hemidiaphragmatic paralysis as a manifestation of familial brachial plexus neuropathy]. / Parálisis hemidiafragmática como manifestación de la plexopatía braquial familiar.

We present a patient with familial brachial plexus neuropathy (FBPN) who is in the second generation of a family found to have this disease. The patient suffered phrenic paralysis, which has only been previously described in association with FBPN in 4 similar cases, all of which also involved the left phrenic nerve. The side of phrenic paralysis's was unrelated to the side where brachial plexus lesions occurred. We believe that paralysis of the diaphragm, although rare, can be considered a sign of FBPN and that therefore this disease should be included in the differential diagnosis of such paralysis. This is particularly so whenever family or personal history suggest that the peripheral nervous system may be involved, compromising the brachial plexus, or whenever facial or digital dysmorphia is present.

[Association of dystrophinopathy with facial-scapular-humeral dystrophy in the same family]. / Asociación de distrofinopatía y distrofia facio-escápulo-humeral en una misma familia.

We present the association of a distrophinopathy with a case of facioscupulohumeral dystrophy in two individuals belonging to the same family. The discrepancy in the seric creatinphosphokinase (CPK) of the two patients together with certain clinical data suggests the possibility that it is a question of two different processes. This impression was confirmed later through dystrophine analysis and genetic examination techniques. This case drew attention to the vital need today to insist on a combination of genetic examinations and dystrophine analysis when diagnosing muscular dystrophies, thus avoiding mistakes derived from diagnostic assumptions made on the basis of antecedents in the family involving neuromuscular disorders and the consequences that this might have regarding vital prognosis and advice to the family. This is the first case of coincidental association of these two processes within one family that has so far come to our knowledge.
