[Importance and factors related to chronic fatigue in multiple sclerosis].

INTRODUCTION: The importance of fatigue in multiple sclerosis (MS) is determined by its high frequency and it is an important cause of disability. OBJECTIVE: To determine factors that are related to the presence of chronic fatigue in patients with MS. PATIENTS AND METHODS: The series comprises patients with MS, consecutively attended in the demyelinizating diseases unit, who met the following criteria: clinically definite MS (RR or SP), MS duration of more than two years, and no relapses during the previous month. Analyzed variables were as follows: chronic fatigue, demographic data, functional systems, EDSS, ISS, ESS, disease activity, Hamilton, depression scale GHQ-28, PSQI, and interferon. Statistical study: bivariate and multivariate analysis by logistic regression. RESULTS: A hundred patients were included, 72 female and 28 male. Mean age was 39.27 years. Of the 100 patients 88 had RR disease and 12 SP disease. MS mean duration was 11.2 years. Mean EDSS 2.54. Chronic fatigue was 53 %. The presence of depression increased the probability of chronic fatigue 3.6 fold, and every point in PSQI-7 increases it 3.5 fold. CONCLUSION: Depression and the PSQI-7 subscale (day sleep dysfunction) are the only variables independently related to chronic fatigue in patients with MS.

[Sleep disorders in multiple sclerosis].

INTRODUCTION: To determine the frequency of sleep disorders in multiple sclerosis (MS) patients and their relation with other manifestations of the disease. METHODS: Selected patients had clinically definite MS (relapsing-remitting and secondary progressive forms) and duration of the disease over two years. They were serially evaluated at the unit of demyelinating diseases of a third level hospital. The following scales were applied: the Pittsburgh Sleep Quality Index, the Hamilton Depression Rating Scale, EDSS, ISS and ESS. Statistical analysis by means of non parametric test and logistic regression was carried out. RESULTS: One hundred patients were included (72% women and 28% males). Mean age was 39 years. Eighty eight were relapsing-remitting forms and the rest secondary progressive forms. Mean EDSS was: 2.5. Mean duration of evolution: 11.2 years. The prevalence of sleep disorders was 36%. Age, sex, evolutionary form, degree of disability and chronic fatigue did not relate with the sleep disorders in these patients. In the multivariant analysis by means of logistic regression, we found that every point more in Hamilton's scale multiplies the probability of presenting sleep disorders by 1.2. CONCLUSIONS: Depression is the only variable that independently relates, with the presence of sleep disorders in MS patients.

[Neurocutaneous melanosis].

INTRODUCTION: Neurocutaneous melanosis is an infrequent condition characterized by the presence of numerous gigantic cutaneous naevi and melanocytic infiltration of the central nervous system and/or the leptomeningeal layers. Different clinical features may be seen: endocranial hypertension due to hydrocephalus, cranial nerve paralysis, myelopathy, convulsive seizures, etc. The prognosis is considered to be malignant. Only positive CNS histological findings confirm the diagnosis. CLINICAL CASE: We present the case of a man with cutaneous lesions compatible with the diagnosis of neurocutaneous melanosis since birth, with benign self-limiting epilepsy in early childhood. Cerebral CT and MR scans were normal until the age of 17, when hipper-signal lesions appeared on MR, infiltrating the leptomeninges of the deep temporal pole and anterior aspect of the cerebral peduncles, which suggested the presence of melanocytes in the CNS. CONCLUSIONS: There are cases of neurocutaneous melanosis with a good medium-term prognosis and benign manifestations until infiltration of the CNS occurs. Then they start to show the classical behavior of cases with a malignant prognosis. MR should be included as part of the diagnostic criteria for neurocutaneous melanosis. MR should be done periodically in patients with cutaneous lesions suggestive of this condition.

[Determining factors in decisions regarding cardio-pulmonary resuscitation in patients with cerebral hemorrhage].

INTRODUCTION AND OBJECTIVE: Some medical factors related with cardiopulmonary resuscitation (CPR) outcome are known. Moreover, there are other factors, not strictly medical ones, as age, gender, race and socioeconomic status, that influence on decisions of CPR. The aim of this study was to analyse the influence of all this factors on in-hospital CPR of the patients with intracerebral hemorrhage. MATERIAL AND METHODS: This retrospective study comprised all the consecutive patients hospitalized with spontaneous intracerebral hemorrhage who died within 30 days of hospital admission in a public hospital during the period 1987-1994. We used stepwise logistic regression to identify variables that had a significant independent relation with decision of CPR. RESULTS: We identified 73 patients, 50 men and 23 women. Their mean age was 61 years. RCP was performed in 25 patients (34%). A logistic regression revealed that age (OR 0.8), Glasgow score on admission (OR 0.67) and time of death (OR 1.2) were significantly associated with CPR decision. CONCLUSIONS: CPR was less probable in aged even though they had better level of consciousness on admission. Moreover, CPR was less probable early in the morning.

[Etiology in complex partial epilepsy. I. Neuroimaging studies].

With the appearance of MR, a great advance has been made in the study of the aetiology of epilepsy. This technique can show anomalies not detected in CT scans, obtain images of multiple planes, improve the differentiation of cerebral tissues and allow improved visualization of the temporal lobe, making it very useful in the study of patients with complex partial crises (CPC). We studied 151 epileptics with CPC by means of CT scan and MR in all cases; the anomolous topography was the same in all cases, but the diagnosis was not. In patients with a previously normal CT scan, on MR anomalies were detected in 24 cases. We found a statistical differences on evaluation of the MR anomaly depending on whether the CT scan was normal or abnormal. Statistical differences were also found when there were a greater number of anomalies on MR depending on the frequency of crises at the onset of the disorder.

[Early presentation of crises and the development of epilepsy in cerebral intra-parenchymatous hemorrhage].

PATIENTS AND METHODS: Of a total of 283 patients with spontaneous or hypertensive cerebral intraparenchymatous hemorrhage, 18 (6.3%), with no previous epilepsy, had crises whilst being followed-up for a period of between 2 and 7 years. In 14 cases the hematoma was lobar and 4 involved the basal ganglia or thalamus. In 8 cases (2.8% of all hemorrhage), these crises occurred during the first 24 hours, or as a first symptom of intraparenchymatous hemorrhage. One patient presented with status epilepticus with generalized crises and two had subentrant secondarily generalized partial crises at the time of the ictus. Treatment with anti-epileptic drugs was started in 13 patients. Twelve patients (4.2% of the hemorrhages) developed symptomatic epilepsy with partial crises with or without secondary generalization. RESULTS AND CONCLUSIONS: The maximum rate of recurrence was four crises per year. However, in one patient, reduction of the dose of medication led to the appearance of status epilepticus. Patients with crises of late onset developed epilepsy more often than those who had early crises. In those with crises there was a predominance of bilobular involvement with participation of the parietal lobe and extension of the hematoma or oedema to the cerebral cortex.

[Aspects of neuropathy in mitochondrial diseases].

INTRODUCTION: The existence of neuropathy has been described in mitochondrial disorders such as MELAS, MERRF, Leigh's syndrome, the Kearns-Saye syndrome, myoneurogastro-intestinal encephalopathy and progressive external ophthalmoplegia and constitutes a basic component of the NARP (neuropathy, ataxia and retinosis pigmentosa). However, the general prevalence of the neuropathy and its characteristics within the mitochondrial encephalopathies is not well understood. OBJECTIVES: To characterize the neuropathy and try to establish a genotype-phenotype correlation. PATIENTS AND METHODS: Within study guidelines, we made a retrospective study of 27 patients, diagnosed as having mitochondrial disease, who had had neurophysiological studies (EMG-ENG). In those in whom neuropathy had been found we analysed the clinical, neurophysiological and genetic characteristics. RESULTS: Neuropathy was present in 37% of the patients who had an average age of 13 years, ranging from 1 to 25 years. Syndromic diagnoses were: 7 encephalomyopathies, one MELAS, one MERRF and one NARP. Four of the patients were classified genetically. In all but two of the patients the neuropathy was asymptomatic. The biochemical alterations seen were: deficit of Complex 1 in 3 patients, of complex III in 3 patients, of complex IV in 2 and of pyruvate dehydrogenase in one patient. The type of neuropathy found was varied, with predominance of axonal-type motor neuropathy but no correlation with either biochemical defects or genetic diagnosis. CONCLUSIONS: Neuropathy is a common finding in mitochondrial disorders and probably is under-diagnosed. The axonal form predominates. We have not been able to establish correlations between phenotypes and genotypes.

[Reasons for requesting neuroimaging studies in the evaluation of primary headache].

INTRODUCTION: There is some controversy concerning the need to perform neuroimaging studies in patient complaining of headache. 90% of the people had a complaint of headache during their life, and it is impossible to perform neuroimaging studies in all of them. OBJECTIVE: The aim of this study is knowing the reasons for indications neuroimaging studies in the evaluation of primary headaches and the effectiveness at the diagnosis. PATIENTS AND METHODS: The clinical records of patients who a neuroimaging study was performed for headache during 1998 were retrospectively studied. We analysed in all patients: the age, sex, diagnosis of headache, suspicion of diagnosis, reason and time for indication the neuroimaging study, and if the study modified the diagnosis. RESULTS: During 1998, were performed 107 neuroimaging studies in 96 patients. The mean age were 38 years. 60% were females. The suspicion of diagnosis was primary headache in 71% patients. Only one patient had an abnormality. The reasons for applying a neuroimaging study were: in 20 of the patients the migraine was more frequent and they didn t relieve with abortive drugs, in 20 there was a migraine aura, in 11 because the migraine turned to daily headache, in 17 the family asked for a neuroimaging study, there was a 17 of patients seemed to have an organic disease, in 2 the headache appeared daily, and in 7 of the cases weren't any reasons. CONCLUSIONS: Headache is the most frequent reason for asking a neuroimaging study. Primary headache is the type of headache that justifies most of indications. The most frequent reasons for performing a study were common changes in characteristics of migraine.
