OBJECT Hydrocephalus is one of the commonest complications of tubercular meningitis (TBM), and its incidence is increasing with the HIV epidemic. Literature evaluating the role of ventriculoperitoneal shunts in HIV-positive patients with TBM and their long-term prognosis is scarce. METHODS Between June 2002 and October 2012, 30 HIV-positive patients with TBM and hydrocephalus underwent ventriculoperitoneal shunt placement. Thirty age-, sex-, and grade-matched HIV-negative patients with TBM and hydrocephalus were randomly selected as the control group. Outcome was analyzed at discharge (short-term outcome) and at follow-up (long-term outcome). Univariate and multivariate analyses were performed to look for predictors of outcome; p < 0.05 was considered significant. RESULTS There were no differences in the clinical, radiological, or biochemical parameters between the 2 groups. Short-term outcome was better in the HIV-negative group (76.7% improvement) than in the HIV-positive group (70%). However, the long-term outcome in HIV-positive patients was very poor (66.7% mortality and 76.2% poor outcome) compared with HIV-negative patients (30.8% mortality and 34.6% poor outcome). Seropositivity for HIV is an independent predictor of poor outcome both in univariate and multivariate analyses (p = 0.038). However, in contrast to previous reports, of 5 patients with TBM in good Palur grades among the HIV-positive patients, 4 (80%) had good outcome following shunt placement. CONCLUSIONS The authors recommend that shunt treatment should not be performed in HIV-positive patients in poor Palur grade with hydrocephalus. A trial of external ventricular drainage should be undertaken in such patients, and shunt treatment should be performed only if there is any improvement. However, HIV-positive patients in good Palur grades should undergo VP shunt placement, as these patients have better outcomes than previously reported.

✓Osteochondromas are the most common benign bone tumor. Although the metaphysial region of long bones is the usual site of these tumors, the vertebrae may be infrequently affected. The presentation may vary from typical compressive myelopathy to radiculopathy or radiculomyelopathy, depending on the site of involvement. The authors present 3 consecutive cases of cervical spine osteochondromas encountered over 3 years at their institution, each different in its site of involvement, presentation, and chosen treatment. The patient in Case 1 had the typical presentation and lesion site, and was treated with a conventional laminectomy. The patient in Case 2 presented with an extensive disease that required complex, staged surgery with spinal fusion and instrumentation. The patient in Case 3 presented with monoradiculopathy and had a facet joint osteochondroma that was successfully treated with a simple partial facetectomy, without laminectomy.

OBJECTIVEMultiple-site neural tube defects (MNTDs) are very uncommon, with the predominant number of cases being reported in developing countries. The classic theory of neural tube closure fails to explain the occurrence of these defects. Multisite closure theory, first proposed in 1995, explains most of the occurrences with a few modifications specific to a few defects. In this paper, the authors endeavor to explain all the defects, along with their genetic and embryological bases, and to review the available literature and discuss their own experience in the management of these complex cases.METHODSThe authors retrospectively reviewed the data of all the patients treated surgically for MNTDs over that past 14 years. All possible demographic data, clinical details, and radiological imaging data were reviewed. In addition, surgical parameters, complications, and status at follow-up of more than 12 months were evaluated. All previously reported cases of MNTD were analyzed, and comparisons with the present series were made.RESULTSA total of 3 major series (including the present one) on MNTDs have been from India. A total of 57 such cases (including those of the present series) have been reported in the available literature. While previous series reported a higher incidence of spinal defects, the present series had a higher rate of cephalic defects (55%). Among the reported cases, insertion of a ventriculoperitoneal shunt was necessary in 12 (26%), and only 4 patients were operated on in 2 stages. Neurological status at presentation dictated outcome.CONCLUSIONSMNTDs are extremely rare, and their embryogenesis is different from that of single neural tube defects. Simultaneous repair of 2 or even 3 defects is possible in a single-stage surgery. The requirement of a shunt is uncommon, and complications following surgery are rare. Folic acid supplementation may reduce the incidence of defects.

Decompressive craniectomy in a selected cohort of patients had a good outcome in a majority of the patients: 26 of 34 in this study had a GOS score of 4 or 5. In this series, which is the largest in the available literature, the authors review their experience and recommend usage of this procedure in selected patients.

Purpose: Intracranial aneurysms in children are rare compared to those in adults, and their causes, presentations, and outcomes also vary. Thus, they need to be studied intricately and as an independent entity. Methods: We retrospectively reviewed intracranial saccular aneurysms in 44 children of <19 years of age who had been surgically treated during the last 30 years at our institute. We analyzed presentation, characteristics, size, multiplicity, cause, and eventual outcome, and compared these to the adult cases of aneurysms operated on during the same period. Results: The commonest site of aneurysm was the internal carotid artery (ICA), in 47.7%. Follow-up was available for 38 (86.4%) children. The median duration of follow-up was 14 months (range 1-89 months). A favorable outcome was seen in 31 cases (81.6%) and an unfavorable outcome (including 1 death) in 7 (18.4%). Conclusion: Intracranial aneurysms in children present with subarachnoid hemorrhage in a good grade. ICA bifurcation aneurysms are the commonest sites of occurrence. Surgery is safe and effective, and children seem to have a better outcome.
