Multineuritis craneal y mielitis transversa como complicaciones de una meningitis neumocócica / Cranial multineuritis and transverse myelitis as complications of pneumococcal meningitis

Introducción: La meningitis neumocócica es una patología que asocia una elevada tasa de morbimortalidad. Caso clínico: Presentamos el caso clínico de un varón de 41 años que, tras una meningitis causada por Streptococcus pneumoniae, tuvo como complicaciones posteriores una mielitis transversa torácica que le ocasionó una plejía en las extremidades inferiores, abolición de todas las modalidades sensitivas y trastornos disautonómicos, así como una alteración de las astas anteriores a nivel cervical que produjo plejía en las extremidades superiores, pero con conservación de la sensibilidad. Esto plantea un diagnóstico diferencial entre la afectación denominada ‘poliomielitis like’ y una encefalomielorradiculitis diseminada aguda. La exploración y el estudio radiológico y neurofisiológico avalaron una recuperación clínica completa en las extremidades superiores, gracias, en parte, a una neurorrehabilitación precoz. Conclusiones: Las complicaciones medulares en el contexto de una infección del sistema nervioso central son muy infrecuentes. La afectación medular de astas anteriores se ha descrito únicamente de forma anecdótica, y no se han encontrado referencias bibliográficas que la asocien con S. pneumoniae.(AU)

Introduction: Pneumococcal meningitis is a condition associated with a high rate of morbidity and mortality. Case report: We report the clinical case of a 41-year-old man who, following meningitis caused by Streptococcus pneumoniae, developed subsequent complications such as thoracic transverse myelitis, which caused paralysis in the lower extremities, abolition of all sensory modalities and dysautonomic disorders, as well as an alteration of the anterior horn cells at the cervical level that produced paralysis in the upper extremities, but with preservation of sensibility. This implies the need for a differential diagnosis between what is known as ‘poliomyelitis-like’ disorder and acute disseminated encephalomyeloradiculitis. The examination and the radiological and neurophysiological study showed a full clinical recovery of the upper extremities, thanks in part to early neurorehabilitation. Conclusions: Complications of the spinal cord within the context of infection of the central nervous system are very rare. Involvement of the anterior horn cells of the spinal cord has only been described anecdotally, and no bibliographical references have been found that associate it with S. pneumoniae.(AU)

Epidemiology and characteristics of ischaemic stroke in young adults in Aragon.

INTRODUCTION: Stroke affects around 15 million people per year, with 10%-15% occurring in individuals under 50 years old (stroke in young adults). The prevalence of different vascular risk factors and healthcare strategies for stroke management vary worldwide, making the epidemiology and specific characteristics of stroke in each region an important area of research. This study aimed to determine the prevalence of different vascular risk factors and the aetiology and characteristics of ischaemic stroke in young adults in the autonomous community of Aragon, Spain. METHODS: A cross-sectional, multi-centre study was conducted by the neurology departments of all hospitals in the Aragonese Health Service. We identified all patients aged between 18 and 50 years who were admitted to any of these hospitals with a diagnosis of ischaemic stroke or TIA between January 2005 and December 2015. Data were collected on demographic variables, vascular risk factors, and type of stroke, among other variables. RESULTS: During the study period, 786 patients between 18 and 50 years old were admitted with a diagnosis of ischaemic stroke or TIA to any hospital of Aragon, at a mean annual rate of 12.3 per 100 000 population. The median age was 45 years (IQR: 40-48 years). The most prevalent vascular risk factor was tobacco use, in 404 patients (51.4%). The majority of strokes were of undetermined cause (36.2%), followed by other causes (26.5%). The median NIHSS score was 3.5 (IQR: 2.0-7.0). In total, 211 patients (26.8%) presented TIA. Fifty-nine per cent of the patients admitted with a diagnosis of ischaemic stroke (10.3%) were treated with fibrinolysis. CONCLUSIONS: Ischaemic stroke in young adults is not uncommon in Aragon, and is of undetermined aetiology in a considerable number of cases; it is therefore necessary to implement measures to improve study of the condition, to reduce its incidence, and to prevent its recurrence.

[Evolution of the demand for ambulatory neurological care and pathologies attended in neurology clinics in the health care district of Tortosa, Tarragona]. / Evolución de la demanda de asistencia neurológica ambulatoria y patología atendida en la consulta de neurología de la región sanitaria de Tortosa, Tarragona.

AIMS: An analysis was conducted to determine whether there were any changes in the demand for health care, demography and pathologies attended in outpatient departments within the health care district of Tortosa between 1997 and 2003. PATIENTS AND METHODS: Data about the demand for and attendance at first neurology visits over the period 1997 and from March 2003 to February 2004 was collected prospectively. Information concerning age, sex, groups of pathologies, diagnoses, rates of requests for first visits, source of the demand and destination after the visit were compared. RESULTS: Mean age rose from 49 to 56 years (p < 0.001). Patients above 70 years of age increased from 23.7% to 35.9% (p < 0.001), while in the population within the area the figure only rose from 15.8 to 17.1%. The proportion of females went up from 52 to 62% (p < 0.001). Demand (that is, the rate of requests for first visits per 1000 inhabitants per year among those over the age of 15) rose from 8.5 to 9.3, 9.8% (p = 0.03). Demand from primary care increased from 52 to 69% (p < 0.001). Cognitive disorders (6.5% and 15.9%) grew by 144.6% (p < 0.001). Headaches (23.9% and 24.1%), the largest diagnostic group, and non-neurological diagnoses (18% and 18.5%) remained unchanged (p = NS). No changes were observed in the number of discharges in the first visit: 22.8% and 21.1% (p = NS). CONCLUSIONS: The most striking results are the increase in demand (mainly from primary care), the increased age of the population attended and the notable growth in the number of cognitive disorders. These quantitative and qualitative changes in the demand increase the need for resources.

[Evaluation study of the chronic headache questionnaire]. / Estudio de validación de un cuestionario para cefaleas crónicas.

INTRODUCTION: Semi-structured questionnaires, based on clinical criteria are used in the diagnosis of headache, but none has been used to study the two commonest types of chronic headache. The first step, before clinical application, is to carry out a study of the questionnaire's validity and predictive value. OBJECTIVE: The objectives of our study were to evaluate the validity and determine the effectiveness of the ZZA questionnaire in the differential diagnosis between transformed migraine (TM) and chronic tension headache (CTH), in a specialist Neurology Clinic. MATERIAL AND METHODS: The ZZA questionnaire, elaborated by one of the investigators, was made up of 20 questions aimed at TM, CTH or the chronicity of the headache. An observer, who did not know the diagnosis, gave the questionnaire to patients who had previously been diagnosed by the head of the Headache Clinic as having TM or CTH. The process of validation of the questionnaire consisted in showing that it was reliable, with valid contents and valid criteria. RESULTS: On analysis of reliability, the items ZZA1, ZZA15, ZZA16 and ZZA18 gave the highest indices. The Cochran Q test showed lack of uniformity of replies. Only ZZA1, ZZA15 and ZZA18 were predictive items showing MT. None of the questions to show CTH were predictive. After final adjustment the definitive model was made up of ZZA1, ZZA15 and ZZA18. CONCLUSIONS: The proposed questionnaire was not found to be useful for differential diagnosis between TM and CTH. Only 3 of the 20 questions were accepted as having some degree of validity and effectiveness. Two of these 3 questions, based on clinical impressions of the author, might well be included in the diagnostic criteria of TM.

[Neurophysiological studies of headaches]. / Estudios neurofisiológicos en cefaleas.

INTRODUCTION AND OBJECTIVE: The diagnosis of headache is based on the clinical criteria suggested by the IHS in 1988. The neurophysiological examinations often used in the study of headache may support the clinical diagnosis and give information as to the prognosis. The objective of this paper is to review the neurophysiological examinations most often used in the clinical and pathological investigation of headache. DEVELOPMENT: As shown by recent studies, the EEG is of little value in the routine evaluation of a patient with headache. However, it may be useful as an exploratory test for underlying pathology in atypical headache or when intra-cranial pathology is suspected. Evoked potentials, when used to study migraine, show absence of Habituation (or Potentiation) in migraine patients. This finding may represent abnormality in the processing of information at a cortical level in these patients. There is a tendency to unify the theory of neurone hypoxia and the absence of Habituation in Migraine as a single hypothesis of pathogenesis. Negative Contingent Variation has proved to be clinically useful to optimize treatment in Migraine. The electromyogram and Muscle Reflexes have been used in the study of Tension Type Headaches, ES2 changes, showing brainstem antinociceptive reflexes support the participation of a central factor in the origin of chronic Tension Headache. CONCLUSION: Neurophysiological tests may be useful in investigation of the pathology of headache since they permit a functional study of many neurone paths and the action of drugs on the central nervous system.

[Neuropathic beriberi as a complication of surgery of morbid obesity]. / Beriberi neuropático como aplicación de la cirugía de la obesidad mórbida.

We describe a women of 22 years of age who had had a vertical gastroplasty (as treatment for morbid obesity). She was admitted to hospital with a 4 week history of nausea and vomiting of food. Treatment with intravenous dextrose, without vitamin supplements was started. One week later she complained of diplopia, paresthesia and weakness of the limbs. All investigations proved to be normal. A deficiency state was suspected, probably Wernicke's encephalopathy, although no alterations were seen in her mental state. We started treatment with high doses of parenteral thiamine, other vitamins and a suitable diet. The treatment was followed by complete recovery. Few neurological complications have been described in association with vertical gastroplasty. The commonest are polyneuropathies. The probable deficiency origin of these is considered. We emphasise the importance of vitamin supplements following the surgical treatment of morbid obesity to avoid the development of deficiency states. Wernicke's encephalopathy is due to thiamine deficiency. It may be associated with any type of malnutrition, not only with chronic alcoholism. The full clinical triad which is diagnostic of this condition is only present in one third of the cases. When the condition is suspected on clinical grounds treatment should be started early to avoid the occurrence of irreversible secuelae.
