Cerebral infarction (CI) is a serious complication of tuberculous meningitis (TBM). It can be asymptomatic or symptomatic, causing stroke. We studied 40 TBM patients. All had initial CT brain scan, CT/MRI scan 3 months later and urgent for deterioration. CI was classified into lacunar (LI) large artery (LAI). Twelve (30%) CI, in 9 (23%) it symptomatic (8%) silent. Seven (58%) LAI +/- LI. Eight (67%) multiple CI. Two died from brainstem 6 were dependent at 1 year. Patients with might develop...
Middle cerebral artery (MCA) blood flow velocity was measured daily by transcranial Doppler ultrasonography in 121 patients with severe (50), moderate (16) and minor (55) head injury during their hospital stay, the results compared findings control subjects. Admission MCA significantly lower after 35.8 (31.9-39.7) cm/s, mean (95% confidence limits), 45.5 (40.0-51.0) cm/s 51.7 (47.9-55.5) when normal controls 60.1 (56.9-63.3) cm/s. Initial than injury. At discharge, remained below 46.2...
To successfully match the treatment to cause for raised intracranial pressure (ICP) after a severe head injury, it is important know underlying mechanism at given moment pressure. In particular, distinguish between active cerebral vasodilation, indicating functional autoregulation, and passive vascular dilation as ICP. An experimental study was performed in feline models of diffusely ICP (n = 6), arterial vasodilation caused by hypercarbia pharmacologically induced hypertension 6) determine...
Worldwide, the incidence of motor neuron disease (MND) has been increasing steadily over recent decades. We reported a follow-up epidemiology study MND in this locality.We identified subjects from computer database government hospital system between I January 1997 and 31 2002 by searching ICD code starting 335.xx. Every retrieved case or their records were reviewed validated neurologist(s) responsible regional hospitals which patients attended. One hundred twenty cases seven (serving 48.05%...
• Focal myositis is an inflammatory pseudotumor of skeletal muscle that may involve the head and neck. It can closely mimic either a neoplastic or infectious process. We present case 7-year-old boy with 2-week history painful, unilateral neck swelling, fever, torticollis. He failed to respond antibiotic therapy required open exploration. An incisional biopsy indurated, tissue adherent his sternocleidomastoid showed focal myositis. unusual, but important possibility in differential diagnosis...
Eleven patients with raised intracranial pressure caused by cerebral cryptococcosis developed complications requiring neurosurgical operations. Two were fully conscious on admission, and 9 had impaired consciousness, four of whom comatose. Seven found to have hydrocephalus only. edema initially, 2 cystic lesions. One the latter subdural effusion. All eventually progressive placement a ventriculoperitoneal shunt. Four initially treated external ventricular drainage. When drainage was used...
A retrospective review of 526 patients who underwent neurosurgery for nontraumatic conditions over a 5-year period revealed 36 (6.8%) with endoscopically and or surgically documented postoperative gastrointestinal (GI) complications. Two had GI bleeding perforation, the remaining only. Multivariate analysis indicated 5 factors that were independent significance in predicting development These included 1) inappropriate secretion antidiuretic hormone, 2) preoperative coma (Glasgow Coma Score...

Ischaemic brain damage is present in over 90% of patients suffering from fatal head injury. Early detection and treatment ischemia may improve outcome after trauma. Monitoring blood flow velocity the middle cerebral artery by noninvasive transcranial doppler ultrasound provides an alternate means identifying ischaemia.
Mycobacterium fortuitum is a rare cause of central nervous system infection; however, shunt infection caused by this organism has not been reported. We report case subsequent to insertion ventriculoatrial for obstructive hydrocephalus cerebellar hematoma.

To evaluate RV longitudinal function in pulmonary hypertension (PH) patients by Two-dimensional strain (2DS). 41 with PH were prospectively studied along 40 control patients. 2DS and right heart catheterization performed, peak systolic strain(S) rate (SRs) obtained from basal to apical free wall calculated. Deformation indices compared values of conventional echocardiography the use linear regression. (1) S, SRs all segments group significantly lower than those (P <0.05); middle segment...
