INTRODUCTION Aseptic meningitis is a process that is characterised by an inflammatory reaction of the meninges that is not due to any infectious agent. Its aetiology is varied and is most frequently caused by rheumatologic and/or autoimmune processes, chemical or medication-induced meningitis, the most notable drugs involved being antibiotics and(More)
INTRODUCTION Mitochondrial encephalomyopathies belong to a heterogeneous group of diseases with a range of neurological symptoms caused by a dysfunction somewhere in the nervous system. They may arise from mutations of the mitochondrial DNA or nuclear DNA in the genes that code for the subunits of the respiratory chain. The results obtained from using(More)
INTRODUCTION Parotiditis is a viral infection that produces a non-suppurative inflammation of the parotid glands, although it may affect other salivary glands, the testicles, meninges and the pancreas. Clinical meningitis appears in 1-10% of cases, normally between the 4th and the 10th day after infection of the parotid glands. In this study, we analyse the(More)
INTRODUCTION Horner syndrome (HS) is produced by damage to the oculosympathetic pathway and gives rise to palpebral ptosis, enophthalmos and myosis. Anhidrosis also occurs in cases in which the lesion is located before the separation of the vasomotor and sudomotor fibres at the start of the internal carotid artery. Nasopharyngeal cancer may damage the(More)
INTRODUCTION Tolosa-Hunt syndrome is caused by an unspecific inflammation in the cavernous sinus or superior orbital fissure. Recurrence occurs in 40% of cases. Magnetic resonance (MR) of the head and orbital phlebography can reveal characteristic data, although diagnosis is reached by exclusion according to International Headache Society criteria.(More)
INTRODUCTION Multiple sclerosis (MS) often presents with sensory symptoms, which are usually due to spinothalamic or spinal cord disorders; parietal syndrome is, however, very rare as the initial symptom. Likewise, aphasia is also an infrequent symptom of MS; in the few cases that have been reported, it is usually linked to the existence of important(More)
INTRODUCTION Transient global amnesia is a syndrome mainly characterised by an anterograde memory deficit, which disappears in less than 24 hours without leaving any kind of sequelae. Its aetiopathogenesis is still unclear. The ischemic theory became important after hypoperfusion was observed in the mesial region of the temporal lobe using different imaging(More)
INTRODUCTION Electrocution is the cause of a large number of accidents and, of these, a considerable percentage result in death. Several factors affect the severity and distribution of the injuries. It is known that for low voltages the characteristics of alternating current make it three times more dangerous than continuous current. The high percentage of(More)
