RESUMO
The purpose of the study is to highlight the varied presentation of tuberculosis (TB) simulating a brain tumour. Headache and seizures are becoming frequent presenting complaints without any history of tuberculosis. The study comprises 1200 patients of both sexes with ages ranging from ten to sixty years. CT scan and MRI brain control with and without contrast medium were the investigations performed in these cases. In some patients Electroencephalography (EEG), cerebral angiography (DSA) and spectroscopy were also performed. The final diagnosis of tuberculosis was made on the basis of craniotomy, stereotactic and burr hole biopsies with histopathology in most of the cases. Forty per cent of the patients were followed up for eight months. They were put on anti-tuberculosis treatment with symptomatic and anti-epileptic drugs. The incidence was 544 and 757 per 100,000 in Africa and Indo Pakistan respectively. The male to female ratio was 1:1. Tuberculosis, especially with CNS involvement, is not only common in immunosuppressed patients in our setting, but TB has been and remains an important public health problem. TB may involve the CNS either as meningitis or as parenchymal granulomas or abscesses. Patients with brain TB usually present with fever, multiple cranial nerve involvement and occasional behavioural changes. CSF findings remain non specific in most cases. The most common sites are the cerebral hemisphere and basal ganglion in adults and the cerebellum in children. Tuberculosis has unique findings on brain CT and MRI. Cortical and subcortical locations are typical whereas the brain stem is a less common site. Tuberculosis lesions are usually solitary but multiple in 10% to 35% of cases. In spite of all these facts some cases of brain TB still need aggressive neurointervention to reach the final diagnosis of brain TB. Tuberculosis in the CNS may manifest in many different ways. So one should always include tuberculosis in the differential diagnosis in the etiology of delayed onset epilepsy and acute on chronic headache. In case of a discrepancy between clinical manifestations and CT/MRI findings, one can always anticipate tuberculous lesion in the brain.
RESUMO
The provision of comprehensive programme for mental health in the community setting has achieved an important place in the field of psychiatric rehabilitation. The concept of agrotherapy which is based on the philosophy of keeping patients occupied in a rural and agricultural setting with more structured activities has been found to be a promising innovation for the rehabilitation of chronic schizophrenics in this regard. This paper describes the results of a three years follow-up study conducted at Fountain House Farm, Farooqabad to evaluate the effectiveness of agrotherapy. The findings are discussed in terms of practical implications of this innovative approach in the rehabilitation of chronic schizophrenic patients.

Arteriovenous malformations (AVM) are usually located superficially in the subcortical white matter, and seizures are one of the frequently seen presenting features of AVM. The diagnosis of AVM is confirmed with various neuroimaging techniques. The present study comprised six patients presenting with seizures and headaches, referred to the neurodiagnostic unit to rule out/confirm epilepsy. All patients showed epileptiform activity on electroencephalography (EEG). Further investigations, such as angiography supplemented with computed tomography (CT) showed AVM. EEG is usually not considered a valuable diagnostic tool in AVM, but our results support the finding that EEG is an extremely reliable investigative tool, and should be supplemented with angiography and CT scan for better localization of AVM.
