Parkinsonism-hyperpyrexia, a rare consequence of deep brain stimulator malfunction in advanced Parkinson's disease.

Parkinsonism-hyperpyrexia syndrome (PHS) is a rare neurological emergency that shares clinical features with neuroleptic malignant syndrome. It is usually due to sudden deprivation of dopaminergic treatment, although there are cases related to failure of the deep brain stimulation system.

¿Existe relación entre las lesiones de la sustancia blanca asociadas a migraña y el foramen oval permeable? Análisis de una serie de pacientes con migraña crónica / Is there a relationship between white matter lesions associated with migraine and patent foramen ovale? Analysis of a series of patients with chronic migraine

INTRODUCCIÓN: Las lesiones de la sustancia blanca son más prevalentes en los pacientes migrañosos que en la población general, especialmente en los que tienen una alta frecuencia de ataques. El foramen oval permeable se ha descrito como posible nexo de unión entre la migraña y las lesiones de la sustancia blanca. OBJETIVO: Determinar la existencia de una posible relación entre el foramen oval permeable y las lesiones de la sustancia blanca en una serie de pacientes con migraña crónica. PACIENTES Y MÉTODOS: Estudio observacional, unicéntrico, de casos y controles. Se seleccionó a 89 mujeres con migraña crónica. La persistencia y las características del foramen oval permeable se evaluaron mediante un estudio Doppler transcraneal. El foramen oval permeable se clasificó como pequeño, moderado o masivo. Se consideraron permanentes los detectados en reposo, y latentes, el resto. El protocolo de resonancia magnética incluyó imágenes sagitales potenciadas en T1, axiales potenciadas en FLAIR-T2 y secuencia combinada de densidad protónica y T2-FSE. Las lesiones de la sustancia blanca se clasificaron como profundas, periventriculares o ambas. RESULTADOS: La prevalencia de foramen oval permeable (53,6% frente a 48,5%; p = 0,80) y la proporción de foramen oval permeable masivo y permanente fueron similares entre los pacientes con y sin lesiones de la sustancia blanca. Tampoco se encontraron diferencias en la prevalencia (55,6% frente a 52,6%; p = 1,00) o las características del foramen oval permeable en función de la distribución de las lesiones de la sustancia blanca. CONCLUSIÓN: Los resultados no sugieren la intervención del foramen oval permeable en la fisiopatología de las lesiones de la sustancia blanca observadas en pacientes migrañosos

INTRODUCTION. White matter lesions are more prevalent in migraine patients than in the general population, especially those with a high frequency of attacks. A patent foramen ovale has been described as a possible link between migraine and white matter lesions. AIM. To determine the existence of a possible relationship between a patent foramen ovale and white matter lesions in a series of patients with chronic migraine. PATIENTS AND METHODS. Observational, single-centre, case-control study. Eighty-nine women with chronic migraine were selected. The persistence and characteristics of the patent foramen ovale were assessed by means of a transcranial Doppler study. The patent foramen ovale was classified as small, moderate or massive. Those detected at rest were considered permanent, and the others were classified as latent. The MRI protocol included T1-enhanced sagittal images, FLAIR-T2-enhanced axial images, and a proton density and T2-FSE combined sequence. The white matter lesions were classified as deep, periventricular or both. RESULTS. The prevalence of patent foramen ovale (53.6% versus 48.5%; p = 0.80) and the proportion of massive, permanent patent foramen ovale were similar among patients with and without white matter lesions. Neither was there any difference in the prevalence (55.6% versus 52.6%; p = 1.00) or the characteristics of the patent foramen ovale as a function of the distribution of white matter lesions. CONCLUSION. The results do not suggest that a patent foramen ovale intervenes in the pathophysiology of the white matter lesions observed in patients with migraine

Analysis of endovascular treatment of ruptured aneurysms of the middle cerebral artery compared to other anatomical locations.

OBJECTIVE: The objective of this article is to compare the results of endovascular treatment of ruptured middle cerebral artery (MCA) aneurysms with ruptured aneurysms of other anatomic locations. METHODS: Fifty consecutive ruptured aneurysms of the MCA and 209 aneurysms at other anatomical locations were selected retrospectively. We compared epidemiological, clinical and radiological variables, prognosis and complications. RESULTS: The MCA aneurysms had a greater size and a poor dome/neck ratio. There were no significant differences in endovascular technique complications, occlusion rate or rebleeding between the two groups (p > 0.1). There were no significant differences in the mortality and number of dependent patients after one month. CONCLUSION: The endovascular treatment of ruptured MCA aneurysms without hematoma is as safe and effective as other aneurysm localizations. Complication rates, occlusion rates and rebleeding of ruptured MCA aneurysms are comparable to other locations.

¿Se abusa de las técnicas de neuroimagen en pacientes con migraña crónica? Estudio en un área de salud del Principado de Asturias / Is there overuse of neuroimaging procedures in patients with chronic migraine? An study in a Health Area in Asturias, Spain

Introducción. Existe la creencia del abuso de las técnicas de neuroimagen en pacientes con cefalea en nuestro medio. Objetivo. Analizar el consumo de técnicas de neuroimagen, y fundamentalmente de la tomografía computarizada (TC), ya que es de acceso libre en nuestra área, en la práctica clínica habitual en pacientes con migraña crónica (MC). Pacientes y métodos. Se revisan las historias clínicas de una serie de mujeres consecutivas diagnosticadas en nuestra consulta de cefaleas de MC. Se recogieron datos acerca de la realización de técnicas de neuroimagen a todos niveles (urgencias, consultas y pacientes ingresados). Resultados. Se incluyeron 139 mujeres con MC. Un total de 106 pacientes (76%) tenía al menos una TC de cráneo y 28 (20%) dos o más estudios de TC de cráneo. En seis de estas pacientes (21%) existía justificación clínica para la repetición del estudio, pero no en las 22 (79%) restantes. Ya en nuestro servicio se solicitó resonancia magnética (RM) a 59 pacientes (42%). En 43 (73%), la RM fue normal; en nueve (15%) puso de manifiesto lesiones inespecíficas en la sustancia blanca; y en siete (11%) fue patológica, si bien en ninguno de estos casos había relación directa entre la lesión de la RM y la clínica de MC. En 15 pacientes con MC (11%) no se había solicitado ningún estudio de neuroimagen. Conclusiones. En contra de nuestra hipótesis inicial, no encontramos un abuso de las técnicas de neuroimagen en pacientes con MC en nuestra área de salud (AU)

Introduction. There is a general perception of neuroimaging procedures overuse, mainly of CT scan, in patients with headache in Spain. Aim. To analyze the use of neuroimaging techniques, mainly CT scan as it is of free access in our region, in routine clinical practice in patients with chronic migraine (CM). Patients and methods. We reviewed the medical records of a consecutive series of women diagnosed as CM in our headache clinic. The data on consumption of neuroimaging procedures were collected at all levels (emergency department, inpatient ward and neurologic outpatient consultation). Results. We included 139 women with CM. A total of 106 patients (76%) had at least one CT brain scan. Twenty-eight patients (20%) had 2 or more CT scans. In 6 of these patients (21%) there was a clinical reason for repeating the studies, while there was no reason in the remaining 22 (79%). MRI had been carried out in our headache clinic in 59 patients (42%). In 43 (73%) MRI was normal, in 9 (15%) the MRI showed nonspecific lesions in the white matter and in 7 patients (11%) MRI studies were abnormal. There was no direct relationship between MRI lesion and CM. There were 15 patients with CM (11%) without any neuroimaging study. Conclusions. We could not find a real overuse of neuroimaging techniques in patients with CM in our health area (AU)

Surgical adverse events of deep brain stimulation in the subthalamic nucleus of patients with Parkinson's disease. The learning curve and the pitfalls.

BACKGROUND: Several surgical adverse events (SAEs) have been associated with Deep Brain Stimulation (DBS) of the subthalamic nucleus (STN) in Parkinson's Disease (PD) patients, leading to certain confusion about the risk/benefit ratio of this technique, and giving rise to the need of more and more extensive control studies over longer periods. The aim of this article is to identify and quantify the factors associated with the most frequent AEs from STN DBS in PD-diagnosed patients. METHODS: The following variables were studied: aborted procedure, misplaced leads, intracranial haemorrhage, and seizures. This study was carried out in 233 patients diagnosed with PD, with 455 STN electrodes implanted and follow-up after 7 (8-14) years follow up. RESULTS: A total amount of 56 SAEs occurred in 49 patients (11.76 % of total procedures, 12.31 % of implanted leads, 21.03 % of patients). SAEs were: five aborted procedures, 26 misplaced leads, ten intracranial haemorrhages, and 15 seizures. Of all the SAEs, long-term effects only happened in two cases of hemiparesis caused by intracranial haemorrhage; the other SAEs were reversible and didn't leave any long-term clinical consequences (0.42 % of procedures, 0.44 % of leads, and 0.86 % of patients). CONCLUSIONS: STN DBS in PD patients is a safe surgical procedure, with good risk/benefit ratios: procedure reliability/correct lead implantation in 95.59 %, 0 mortality/implanted lead, 0.12 morbidity/implanted lead, and 0.0043 neurological sequelae/implanted lead.

Cardiogenic shock following administration of propofol and fentanyl in a healthy woman: a case report.

INTRODUCTION: Cardiogenic shock is very uncommon in healthy people. The differential diagnosis for patients with acute heart failure in previously healthy hearts includes acute myocardial infarction and myocarditis. However, many drugs can also depress myocardial function. Propofol and fentanyl are frequently used during different medical procedures. The cardiovascular depressive effect of both drugs has been well established, but the development of cardiogenic shock is very rare when these agents are used. CASE PRESENTATION: After a minor surgical intervention, a 32-year-old Caucasian woman with no significant medical history went into sudden hemodynamic deterioration due to acute heart failure. An urgent echocardiogram showed severe biventricular dysfunction and an estimated left ventricular ejection fraction of 20%. Extracorporeal life support and mechanical ventilation were required. Five days later her ventricular function had fully recovered, which allowed the progressive withdrawal of medical treatment. Prior to her hospital discharge, cardiac MRI showed neither edema nor pathological deposits on the delayed contrast enhancement sequences. At her six-month follow-up examination, the patient was asymptomatic and did not require treatment. CONCLUSION: Although there are many causes of cardiogenic shock, the presence of abrupt hemodynamic deterioration and the absence of a clear cause could be related to the use of propofol and fentanyl.

[Sarcoidosis presenting as partial seizures. Report of one case]. / Crisis epiléptica como primera manifestación de sarcoidosis. Caso clínico.

The nervous system is affected in 10% of patients with sarcoidosis. However, neurological disturbances are rarely the first manifestation of the disease. We report a 36-year-old woman presenting with partial seizures that generalized secondarily. Magnetic resonance showed a left parietal cortical-subcortical lesion with a minimal mass effect, moderate vasogenic edema and intense enhancement with intravenous contrast. A magnetic resonance spectroscopy disclosed a low aggressiveness profile, compatible with an inflammatory lesion. Angiotensin converting enzyme levels were normal. The lesion was excised and the pathological study showed the presence of granulomas with dubious necrosis. The patient was treated with antituberculous drugs. One year later, the lesion had grown and a thorax CT scan showed numerous mediastinal and hilar lymphadenopathies. A new determination of angiotensin converting enzyme disclosed elevated levels and the biopsy of mediastinal lymph nodes confirmed the presence of sarcoidosis.

A black mobile mass: diagnosis and management.

The diagnosis and treatment of left ventricular apical thrombi after myocardial infarction are still not well established. Fibrinolytic treatment, heparin treatment and surgical removal might be therapeutic options. We present the case of a 37 year old man who came into the Emergency department complaining of pleuritic chest pain. ECG revealed an evolving anterior wall infarction and transthoracic echocardiogram showed a big mobile thrombus in the ventricular apex. In order to confirm diagnosis and to differentiate other entities like pseudoaneurysm, contrast echocardiography and cardiac MRI with late gadolinium enhancement were performed and allowed a definitive diagnosis. Our patient was treated with intravenous heparin and then with oral anticoagulation. Two months later, echocardiogram showed an apical non-mobile and smaller thrombus.

Evidence of subthalamic PGO-like waves during REM sleep in humans: a deep brain polysomnographic study.

STUDY OBJECTIVES: The aim of this study was to examine whether the subthalamic nucleus (STN) plays a role in the transmission of PGO-like waves during REM sleep in humans. DESIGN: Simultaneous recordings from deep brain electrodes to record local field potentials (LFPs), and standard polysomnography to ascertain sleep/wake states. SETTING: Main Hospital, department of clinical neurophysiology sleep laboratory. PARTICIPANTS: 12 individuals with Parkinson's disease, with electrodes implanted in the STN; and, as a control for localization purposes, 4 cluster headache patients with electrodes implanted in the posterior hypothalamus. INTERVENTIONS: All subjects underwent functional neurosurgery for implantation of deep brain stimulation electrodes. RESULTS: Sharp, polarity-reversed LFPs were recorded within the STN during REM sleep in humans. These subthalamic PGO-like waves (2-3 Hz, 80-200 pV, and 300-500 msec) appeared during REM epochs as singlets or in clusters of 3-13 waves. During the pre-REM period, subthalamic PGO-like waves were temporally related to drops in the submental electromyogram and/or onset of muscular atonia. Clusters of PGO-like waves occurred typically before and during the bursts of rapid eye movements and were associated with an enhancement in fast (15-35 Hz) subthalamic oscillatory activity. CONCLUSION: Subthalamic PGO-like waves can be recorded during pre-REM and REM sleep in humans. Our data suggest that the STN may play an active role in an ascending activating network implicated in the transmission of PGO waves during REM sleep in humans.
