Health-related quality of life using QOLIE-31: Before and after epilepsy surgery a prospective study at a tertiary care center.

Background: Outcome following epilepsy surgery has traditionally been measured in terms of relief of seizures. However, changes in health-related quality of life (HRQOL) after surgery for intractable epilepsy are also important to document. There are no studies on the Indian population which assess the outcome of epilepsy surgery in terms of HRQOL. Materials and Methods: We conducted a prospective study on the patients undergoing epilepsy surgery for intractable seizures, between February 2004 and May 2006 at our center. All patients cleared for epilepsy surgery by the epilepsy surgery team were taken up for study. All patients Results: Thirty-six patients satisfying the inclusion/exclusion criteria were included in the analysis. Twenty-nine of these (Group 1) had good seizure outcome (Engel 1 and 2), while seven patients (Group 2) had poor seizure outcome (Engel 3 and 4) at six months. Overall, 77% of all study patients were completely seizure-free at follow-up. There was no baseline difference in the seven domains of QOLIE-31 between the two groups. There was very significant improvement (P value> 0.005 using paired sample T test) in all the domains of QOLIE-31 in the good outcome group after surgery. Health-related quality of life improvement was seen in all the domains in the poor outcome group also, however, it was statistically significant only for the following parameters: seizure worry, overall QOL, emotional wellbeing, energy fatigue and social functioning domains. Improvement in seizure worry, overall QOL, emotional wellbeing and social functioning was significantly more in Group 1 as compared to Group 2. Conclusion: Complete seizure-free state after surgery is associated with very significant improvement in HRQOL parameters. Several, but not all parameters of HRQOL as assessed by QOLIE-31, improved after surgery even in the poor seizure outcome group. The improvement in domains of seizure worry, overall QOL, emotional wellbeing and social functioning is significantly more in those patients in whom complete seizure-free state is achieved.

Outcome of "unknown" head injury patients at a tertiary care neurosurgical centre.

CONTEXT: A large number of patients are admitted to hospitals in large cities without any identification. These "unknown" patients represent a unique problem in developing countries. There is no systematic study in world literature on this subgroup of patients. AIMS: To elucidate the natural history and outcome of traumatic brain injury patients admitted in the department of neurosurgery as "unknowns". SETTINGS AND DESIGN: Retrospective analysis of all traumatic brain injury patients admitted to the department of neurosurgery as "unknown", between January 2002 and March 2005. RESULTS: Three hundred and twenty five patients were admitted as unknowns over a 3 year and 3 months period. Most of the patients were young males and became known during their hospital stay. Overall, 33 patients stayed for longer than one month, with 4 of them staying for longer than 6 months. Mortality in mild, moderate and severe head injury group was 1%, 6% and 46% respectively. CONCLUSIONS: Unknown patients represent a unique subgroup in metropolitan cities like Delhi. Managing them raises several medico-legal issues. Many of them occupy hospital beds for longer duration than required. There is an acute shortage of rehabilitation homes in Delhi for long term care and rehabilitation of such patients.

Sellar Tuberculoma: An unusual infection.

Tuberculomas are common intracranial lesions in our country. However, tubercular infection of pituitary gland is very unusual. We present a case of intrasellar tuberculoma mimicking pituitary adenoma, and suggest the radiological features and management. A 22-year-old woman had presented with generalized dull aching mild to moderate headache for 8 months and decreased vision in both eyes for 6 months. Visual acuity was 6/9 in both eyes but visual fields and fundus examination were normal. There were no other significant findings. CT scan and MRI (brain) showed a sellar- suprasellar lesion. The pituitary stalk was thickened, as was the mucosa of sphenoid sinus, which raised the suspicion of an infectious pathology other than pituitary macroadenoma. Surgery was performed through sublabial transsphenoid route. A firm, rubbery, yellowish, non-suckable and relatively avascular lesion was found in the sella. Only subtotal decompression was done. Frozen section biopsy was suggestive of inflammatory pathology. Histopathology revealed features compatible with tuberculosis. We suggest that tuberculosis should be considered in the differential diagnosis of sellar lesions, especially if associated with contrast enhancement and thickening of sphenoid sinus mucosa or pituitary stalk, particularly in patients from tuberculosis endemic areas. Most of these patients are negative for workup for systemic tuberculosis. Intraoperatively, a frozen section should be sent and if it shows inflammatory pathology, only a decompression for biopsy should be done. We do not advise radical decompression of these lesions as anti-tubercular treatment is sufficient for cure.

Intraventricular rhabdoid tumor.

Malignant rhabdoid tumor (MRT) most commonly occurs in kidney. In the central nervous system, cerebellum is the most common site of occurrence. CNS rhabdoid tumors typically occur in small children, do not respond favorably to treatment and are usually fatal within 1-year. Here is reported a 4-year-old child who presented with features of raised intracranial pressure. Apart from papillodema, there were no neurological signs. Imaging revealed a left lateral ventricular heterogeneous mass abutting the foramen of monro, with mild irregular contrast enhancement and hydrocephalus. The child underwent right ventriculo-peritoneal shunt followed by craniotomy and gross total tumor resection. He was discharged 10-days after surgery without any neurological deficits. Histopathology revealed features compatible with rhabdoid tumor. Despite radiotherapy and chemotherapy, the child died of progressive disease 10-months after surgery. The highly malignant nature of this tumor makes early diagnosis essential for aggressive management and prognostication.
