Thirty-seven consecutive adults and 2 children with tuberculosis of the nervous system were studied. Twenty-eight patients (72%) had intracranial or intraspinal tuberculomas and only 11 patients (28%) had tuberculous meningitis. Of the 14 patients (36%) with intracranial tuberculomas 6 presented with epilepsy of late onset including convulsive status epilepticus(2). The 6 patients with multiple tuberculomas some of which were situated in the infratentorial compartment were surprisingly free of major neurological disability of systemic disturbance. Thirteen patients (33%) presented with spinal cord compression due to tuberculoma. Eight of these had associated bony abnormalities such as collapsed vertebrae and loss of pedicles usually regarded as characteristic of malignant disease and 2 presented with clinical features of acute transverse myelitis. Eleven patients (28%) had tuberculous meningitis. One of these died, 1 had a protracted illness with gait ataxia and hydrocephalus and 1 other patient was disabled by hemiplegia, dysphasia and epilepsy but the remaining 8 recovered fully. Tuberculosis outside the nervous system was found in 13 patients (33%) in 12 (31%) of whom it was pulmonary. Acid fast bacilli were demonstrated by Ziehl-Neelsen stain in 16 patients (52%) out of 31 from whom specimens were available. Mycobacterium tuberculosis was eventually cultured from only 6 specimens. These data suggest that the clinical and radiological features of tuberculosis of the nervous system in Saudi Arabia may differ substantially from those reported from other countries. In our study there was low morbidity and low fatality rate. Two patients had infratentorial tuberculomas, and 8 patients had bony abnormalities in the vertebral column, typical of malignant disease.

Perinatal ischemic stroke is not rare in term and near-term infants and is an important antecedent of long-term neurological disability, including congenital hemiplegia (hemiplegic cerebral palsy) and seizure and cognitive disorders. Changes in maternal hemostasis occur in pregnancy and are amplified in the period immediately surrounding birth; stroke and other thromboembolic events are more frequent in both mother and infant in this period. The vasculature and hemostatic mechanisms of placenta as well as brain are likely to be important in the pathobiology of perinatal stroke. Maternal and infant thrombophilias, genetic and acquired, play a role. Rarely is >1 child in a sibship affected, and environmental factors-substantially less studied, to date--are likely to be key determinants of risk.

Spontaneous recanalization of the occluded internal carotid artery (ICA) is more frequent than is generally believed. The timing of spontaneous recanalization remains unclear but it may occur as either an early or a late event. The aim of this case report is to emphasize the importance of spontaneous recanalization and its consequences. From September 2008 to November 2010 we prospectively followed patients with old ICA occlusion. The diagnoses of an occlusion were based on duplex scan findings and were confirmed by CT angiography and digital subtraction angiography (DSA). ICA occlusions secondary to dissection, inflammatory process, like fibromuscular dysplasia, previous stenting or endarterectomy and trauma, were excluded from the study. All patients had a scheduled carotid duplex scan every six months. Overall 65 patients were enrolled. Two patients showed evidence of spontaneous recanalization. A 55-year-old man with a known history of transient ischemic attack had occlusion in the left side ICA. He presented with another TIA eight months later. Investigations showed evidence of rcanalization of occluded ICA. This artery underwent uneventful stenting. In another patient recanalization was heralded by global aphasia and right side hemiplegia. He was a 70-year-old man with a history of recurrent TIA. Carotid duplex scan and DSA showed recanalization of the occluded left ICA accompanied by occlusion of the ipsilateral middle cerebral artery. He remained profoundly disabled with severe neurological deficits. In conclusion, spontaneous recanalization of the occluded internal carotid artery is a potentially complicated event that may lead to severe neurological disability.

The diving accident (decompression incident, DCI) occurs in the decompression phase of dives. The DCI can either be caused by an arterial gas embolism (AGE) subsequent to a pulmonary barotrauma or by the formation of inert gas bubbles subsequent to a reduction of ambient pressure during the ascent from depth. In contrast to the traditional assumption that decompression incidents only occur if decompression rules are neglected, recent data indicate that a vast amount of diving accidents occur even though divers adhered to the rules. Hence, there is a large inter- and intraindividual variability in the predisposition for diving accidents. Within the past few years, the molecular understanding of the pathophysiology of diving accidents has improved considerably. It is now well accepted that pro-inflammatory and pro-coagulatory mechanisms play a central role. Moreover, microparticles are increasingly discussed in the pathogenesis of diving accidents. These new molecular findings have not yet resulted in new therapeutic approaches. However, new approaches of preconditioning before the dive have been developed which are intended to reduce the risk of diving accidents. The symptoms of a diving accident show a large variability and range. They reach from pruritus over tension in the female breast, marbled skin and pain in the joints to severe neurological disability like paraplegia or hemiplegia. Furthermore, pulmonary symptoms can be a result of a pulmonary gas embolism and/or a tension pneumothorax. Extreme cases can also manifest as generalized, difficult-to-treat seizures, loss of consciousness or even death. The evidence-based therapy of diving accidents consists of an immediate application of 100% inspiratory O2. This can be performed via a demand valve, face mask with reservoir bag or ventilation bag connected to a reservoir bag. Fluid substitution is performed by i. v. infusion of 500-1000ml/h of cristalloids. If consciousness is not impaired, the diver is positioned in a supine position, in case of impaired or absent consciousness in a lateral recovery position. Especially in severe cases of DCI a fast transfer to a qualified hyperbaric center and the earliest possible hyperbaric O2-therapy is essential.
