RESUMO

Most patients with symptomatic internal carotid artery occlusion have a single minor or major hemispheric stroke. A minority of patients have ipsilateral retinal ischemia, recurrent strokes, or transient ischemic attacks. Whereas spontaneous carotid recanalization is rare, acute surgical recanalization has been attempted, with mixed results. Recently, acute endovascular recanalization has been performed and described as feasible and relatively safe. We describe a patient with symptom recurrence related to hemodynamic factors after occlusion of the carotid artery who was successfully treated 14 days after symptom onset.

RESUMO

INTRODUCTION: Few studies have been carried out on the subject of stratification of medical care for migraines, and even fewer have been conducted with the aim of determining the attitudes adopted by physicians towards their patients when dealing with this issue. Strategia-I and II studies were designed for this purpose. SUBJECTS AND METHODS: The sample consisted of 162 neurologists and 3,168 Primary Care physicians (PCP). Participants in the studies filled out an opinion survey that was produced ad hoc and included the different possible strategies, namely a) Stepped care between attacks (the patient takes medication during several attacks and, if it is not effective, it is replaced by another in successive attacks); b) Stepped care within attacks (the patient treats his or her seizures with medication and, if it does not work, another is used as rescue medication); and c) Stratified care (the physician classifies the patient according to the degree of disability produced by the migraine and recommends the most appropriate drug at the start). RESULTS: Most participants in the study (90.7% of neurologists, 85.2% of PCP) reported using a single strategy. Stratified care was found to be the preferred choice by both collectives (67.6% of neurologists, 43.8% of PCP; p < 0.0001). Only 16% of the respondents admitted using some disability scale. Nonsteroidal antiinflammatory drugs are the medication chosen if disability is mild-moderate, while triptans are preferred if it is moderate-severe (92.9% of neurologists, 78.8% of PCP; p < 0.001). CONCLUSIONS: The strategy based on stratified care is the most widely used in visits to Neurology and Primary Care in Spain, although there are significant differences between the two collectives. Triptans are perceived as being the ideal medication in situations involving moderate-severe disability.

RESUMO

In the present study we have used cell culture assays in order to assess the damage in the haematopoietic system 1 year after peripheral blood stem cell transplantation (PBSCT), and to establish at what level, haematopoietic progenitor cells (HPC) or stroma, this damage occurs. Thirty-one patients, nine breast cancer (BC), 17 non-Hodgkin lymphoma (NHL) and five Hodgkin disease (HD), who had received autologous PBSCT were included. Forty-eight normal subjects who had given informed consent were used as controls. Results were also compared with a matched group of patients (25 cases) prior to PBSCT. Progenitor cells were analysed using CFU-GM and plastic adherent delta (Pdelta) assays. Long-term bone marrow cultures (LTBMC) in one and two stages were established. One year after transplant both the number of committed progenitor cells and the CFU-GM production in LTBMC were significantly reduced in the three groups of patients when compared with controls (P < 0.05 or P < 0.01). Two-stage LTBMC experiments showed that the impairment in CFU-GM production was due to damage in both patients' stroma and haematopoietic progenitor cells (HPC). All patients, except those with HD, showed a decreased stromal layer confluence (P < 0.05), with significant differences in cell composition as compared to normal bone marrow (P = 0.001). When all these variables were compared with pretransplant results, we observed that stroma formation was significantly lower after PBSCT (P < 0.05), while the number of progenitor cells analysed by the Pdelta assay was significantly increased (P < 0.05). We can conclude that even 1 year after PBSCT, both the committed HPC and BM stroma remain damaged.

RESUMO

Amphotericin is a powerful antifungal agent of high toxicity. Encapsulation in liposomes has led to new perspectives although clinical experience is still slight. Four patients, who were neither carriers of antibodies against the human immunodeficiency virus nor neutropenic, diagnosed of meningeal cryptococcosis, pleural aspergillosis, cerebral aspergillosis and ophthalmic candidiasis, respectively and treated with liposomal amphotericin are reported. The treatment was effective and well tolerated. Clinical improvement was observed in the patient with cerebral aspergillosis but magnetic resonance demonstrated persistence of the lesions. Only slight deterioration in renal function was observed in one case and in the other two renal failure improved upon substitution of conventional amphotericin by liposomal amphotericin. The slight systemic toxicity and the absence of local intolerance allowed the administration of high doses and shortening of the therapeutic schedule.

RESUMO

BACKGROUND: Juvenile myoclonic epilepsy (JME) constitutes 10% of all epilepsies. Despite this syndrome being well defined, its diagnosis is usually delayed. The aim of this study was to analyze the clinical and electroencephalographic characteristics to facilitate guidelines to contribute to its recognition. METHODS: From January 1986 to July 1993 the clinical and EEG data of 85 patients with JME were prospectively studied. In 68 cases (80%) the polygraphic study of sleep was also analyzed during a nap period. RESULTS: The series included 44 males and 41 females of a mean age of 28 years (range: 13-63). Fifty-six percent of the cases showed family history of epilepsy and/or febrile convulsions. All the patients had myoclonic crisis with the age of 15 being the mean age of initiation (range: 8-27). Eighty-seven percent also had generalized tonic-clonic crisis and 18% typical absences. Myoclonias were presented daily up the administration of adequate treatment in 60% of the cases with 21% having myoclonic status. The mean interval from the initiation of the myoclonic crisis to diagnosis of JME was of 10.6 years. On monotherapy with valproic acid and following a mean follow up period of 23.8 months, 86% of the patients remained free of crisis. Nonetheless, the rate of recurrence was 100% in the 19 patients who discontinued the treatment. Surveillance EEG was normal on some occasion in 88% of the cases. The most characteristic paroxysms were the following: wave-point at 4-5 Hz and generalized rapid wave-polypoint. Light stimulation provoked a paroxysmal response in one third of the cases. Sleep EEG was abnormal in all the patients. An activation of the paroxysms during non-REM sleep in 78% of the cases and on waking up in 25%. CONCLUSIONS: Juvenile myoclonic epilepsy is a well defined syndrome. Its diagnosis is based on directed anamnesis allowing myoclonic jerks to be collected which often remain unperceived, and EEG exploration with sleep tracing in which the characteristic outbreaks of wave-point or generalized rapid wave-polypoints may be discovered.

RESUMO

INTRODUCTION: Reflex seizures are provoked by a specific sensory stimulus. Approximately 6% of all epileptic patients have reflex seizures. For identification of these seizures it is necessary to take a directed history and make an EEG study whilst the patient is being exposed to the stimulus, which will confirm the diagnosis. DEVELOPMENT: Many stimuli are effective in provoking reflex seizures, the commonest are visual. Amongst the various epileptic syndromes there are different types of epilepsies with reflex seizures which generally correspond to idiopathic generalized epilepsies. The physiopathogenic mechanisms are usually complex. The cerebral cortex corresponding to the function which induces the epileptic crisis is hyperexcitable, and is the cause of an identifiable lesion or dysfunction without an underlying lesion. CONCLUSION: The diagnostic importance of reflex seizures is that when some formerly drug-resistant patients can control the mechanism which triggers off their seizures they attain good control of them.

RESUMO

Our aim was to delimit prognostic factors in supratentorial stroke based on data obtained upon hospitalization. We studied two series of patients, the first being 150 with brain infarct and the second 135 having intracerebral haemorrhage. We analyzed: age, Glasgow and Canadian scales, glucose and urgence haemogram and the size of the lesion across its greatest diameter using computerized tomography (CT). Follow-up time was until death or one year after the stroke. Those who lived longer than one year after were subclassified according to the Rankin scale as < 3 and > or = 3. There was a significant difference between those who survived for less than one month and those surviving more than one year: their age (p < 0.01), average score on the scale (p < 0.001) and size of infarct (p < 0.05) or haematoma (p < 0.001). The Rankin subgroups < 3 and > or = 3 also differed significantly with regard to age. Noteworthy were the unfavourable data: Glasgow < 10 points and Canadian < 5 points, in infarcts > 6 cm and haematomas > 4 cm in diameter. We comment on other evolutionary variables which may influence prognostic assessment such as clinical deterioration or CT sensitivity of the infarct depending on the carry-out time.

RESUMO

INTRODUCTION: Despite the high degree of disability it entails, many patients with migraine have never visited their doctor for this reason. It is necessary to conduct a study to examine the characteristics of first-time visits as a step that must be carried out prior to establishing specific intervention measures for this group of patients. AIM: To determine the profile of the patients with migraine who visit a neurology service for the first time, together with the diagnostic and therapeutic attitudes that neurologists display towards them. PATIENTS AND METHODS: We conducted a cross-sectional, multi-centre study of neurology services across the country. The research included 168 neurologists who recruited 851 patients (74.6% females; mean age: 34.0 ± 10.7 years). Disability was assessed by means of the specific migraine questionnaire (Headache Impact Test) and the generic disability questionnaire (Sheehan Disability Scale). RESULTS: A third (66.5%) of the patients went for consultation following their doctor's advice, while the remaining 33.5% went on their own accord. Only 55.9% had been previously diagnosed with migraine. The main reasons for visiting were ineffective symptomatic treatment (25%) and an increase in the frequency or intensity of the attacks (23.4%). Although 70.3% of the patients had high disability scores on the Headache Impact Test, only 17.4% used specific treatment and only 13.3% were on preventive treatment. CONCLUSIONS: The PRIMERA study confirms, once again, that migraine is an under-diagnosed and under-treated condition in our setting, which means that specific educational interventions and training are still required for this pathology.

RESUMO

INTRODUCTION: Neuromyelitis optica, or Devic's disease, is an inflammatory, demyelinating disease of the central nervous system that selectively affects the optic nerves and the spinal cord, with a high rate of relapses. Anti-aquaporin-4 (AQP4) antibodies are a highly specific marker for this condition. CASE REPORT: A 66-year-old female with longitudinally extensive dorsal transverse myelitis with complete remission following steroidal treatment and later acute relapse, with palsy in one limb. The differential diagnoses considered included a spinal tumour and arteriovenous malformation of the spinal cord. Being positive for AQP4 was the decisive factor in the final diagnosis. CONCLUSIONS: Early detection of anti-AQP4 antibodies together with appropriate immunotherapy can be the key to a better prognosis. An early diagnosis is essential to be able to start treatment at an early stage and thus prevent relapses and severe sequelae.

RESUMO

INTRODUCTION: Migraine has recently been associated to certain personality profiles and styles of coping. AIM: To explore the association between personality factors, disability and the therapeutic management of migraine. PATIENTS AND METHODS: We conducted an epidemiological, cross-sectional, multi-centre study with patients with migraine visiting a neurology unit for the first time. Socio-demographic and clinical data were collected about the patients. The NEO-FFI (Neuroticism-Extraversion-Openness Five-Factor Inventory) was used to evaluate personality factors; the degree of disability was evaluated using the Headache Impact Test (HIT-6) and the number of lost workday equivalents (LWDE) was measured. Bivariate logistic regression analyses were also performed. RESULTS: A total of 736 patients were recruited, of whom 700 were suitable for inclusion in the analysis (75.6% females; mean age: 35.5 ± 11.5 years). In all, 68.9% presented migraine without aura, 1-4 seizures/month (66.7%) and of moderate intensity (58.1%). A total of 76.1% of patients had severe disability according to the HIT-6. Of the 554 active patients, the mean number of lost workday equivalents in the previous three months was 6.8 ± 8.2. Patients showed greater emotional instability than the general population and they scored lower on extraversion, openness, agreeableness and conscientiousness. All the patients were being treated for their migraine: 47.3% by means of stepped treatment between seizures; 39.9% intra-seizures, and stratified in only 12.9%. CONCLUSIONS: This study confirms the impact of migraine in terms of disability and in terms of loss of labour output, together with its association with personality factors.

RESUMO

INTRODUCTION: The International Association for the Study of Pain defines neuralgia as the pain that is felt in the distribution of a nerve or nerve root. Although the most important criterion for its diagnosis is spatial, distinguishing between neuralgia and other types of pain in the craniofacial area will only be possible by looking at a set of many clinical characteristics as a whole. DEVELOPMENT: Knowledge of the territories of sensory distribution of the nerves or roots is essential to be able to define the location of the pain in neuralgias. Other attributes are also useful for diagnosing them: the quality of the pain (paroxysmal, stinging-burning, dull), the time profile (seconds-minutes versus hours-days), the absence of accompanying phenomena other than certain manifestations of sensory dysfunction, especially in the symptomatic forms (hypoanaesthesia, paresthesias, dysesthesias, allodynia, hyperalgesia, hyperpathy), pain triggered by tactile or mechanical stimuli in the painful territory ('trigger' zones) or a positive Tinel's sign, the response to anaesthetic blockade of the nerve or root, and the response to certain drugs. CONCLUSIONS: Although trigeminal neuralgia is the most frequent, there are many other kinds of craniofacial neuralgias, in fact, theoretically, the total number is the same as the number of nerve roots and nerves responsible for the sensory innervation of these anatomical regions. It is essential to be familiar with them to obtain a correct diagnosis.
