ABSTRACT
AIMS AND OBJECTIVES: The alignment of upper and lower cervical spine is presumed to be closely interrelated and the knowledge of this is mandatory when performing occipito-cervical and upper cervical fusions. The aim of this study was to establish standard values for upper and lower cervical spine alignment in the Indian population. MATERIALS AND METHODS: Five hundred eighteen asymptomatic volunteers (261 males and 257 females) between 12 and 80 years of age underwent lateral radiography with their neck in the neutral position. Angles for occipital to 2nd cervical (Oc-C2), 1st to 2nd cervical (C1-C2) and sagittal alignment of 2nd to 7th cervical vertebrae (C2-C7) were measured. Statistical analyses were performed using a statistical package SPSS 10 for windows and the students 't' test. RESULTS: The mean Oc-C2, C1-C2 and C2--C7 angles were 14.66+9.5 degrees , 25.6+7.9 degrees and 16.8+12.7 degrees in male, while same angles in female were 15.59+8.26 degrees, 26.9+6.8 degrees and 9.11+10.4 degrees respectively. Weak statistically significant negative correlation was observed between the measured angles of the upper (Oc-C2 and C1-C2) and lower (C2-C7) cervical spines, which means if the lordosis of the occiput and upper cervical spine increases (if the Oc-C2 angle increases), the alignment of lower cervical spine becomes kyphotic and vice versa. This negative correlation was stronger between the Oc-C2 and C2-C7 angles than between the C1-C2 and C2-C7 angles. CONCLUSIONS: Relationship between alignment of the upper and the lower cervical spine should be taken into consideration when performing cervical fusion.

BACKGROUND: Endoscopic third Ventriculostomy (ETV) is one of the surgical options for obstructive hydrocephalus. There are varying opinions about results of ETV in infants. We are therefore presenting the results of ETV in 54 infants. MATERIALS AND METHODS: A prospective study of 54 infants undergoing ETV in our institution in the last 2 years was carried out. There were 48 cases of congenital hydrocephalus with aqueductal stenosis, 6 of post tubercular meningitis hydrocephalus. Average follow up was 18 months. RESULTS: There was 83.3% (45 cases) clinical success rate in our study. Infection, persistent cerebro-spinal fluid (CSF) leak and bleeding occurred in 4 (8%) cases each while blockage of stoma was observed in 8 (14.8%) patients. Majority of ETV stoma closure (6 out of total 8) occurred following infection (4) or bleeding during surgery (2). One patient (2%) had transient diabetes insipidus. Overall failure rate in our study was 16.7% (8 stoma blocks and 1 procedure abandoned). Low birth weight pre mature infants had higher failure rate (3 out of 5 infants 60%) compared to full term infants with normal birth weight (12.3%). Age did not have any impact on the success rate (P>0.05). Success rates were not significanlty different in patients with aqueductal stenosis (85.4%) and TBM (66.6%) (Fisher's exact test, P=0.3). CONCLUSION: ETV was fairly safe and effective in full term normal birth weight infants while the results in low birth weight pre mature infants were poor.

We report about a 7-year-old female child with cyanotic heart disease whose thalamic abscess was successfully treated by endoscope-assisted abscess drainage. Endoscopic aspiration of thalamic abscess appears to be a safe and effective method of treatment for deep-seated abscesses, as direct visualization of the abscess cavity is possible and the completeness of evacuation can be assessed.

BACKGROUND AND AIMS: A prospective study was carried out to evaluate the lumboperitoneal shunt procedure. MATERIAL AND METHODS: Four hundred and nine patients having communicating hydrocephalus were selected for the procedure during a 10-year period from March 1992 to February 2002. The average follow-up was 45.34 months. RESULTS: Tubercular meningitis (TBM)-related hydrocephalus was detected in 285 patients. Forty per cent of the patients were less than 15 years of age. Glasgow Coma Scale (GCS) of less than 8 was seen in 40% patients and 14.9% patients were in GCS 13-15. At the time of discharge 56.7% patients improved in their GCS to 13 -15 and 14.9% were in GCS 8 or less. The overall mortality was 5.13% and shunt-related mortality was seen in 2% patients. Shunt malfunction requiring revision was seen in 32 patients (7.8%) and the total number of shunt revisions was 44 (11%). Shunt infection was noted in 3.4% patients. CSF leak at the lumbar end occurred in 12 patients. Four patients required conversion of LP shunt to VP shunt. CONCLUSIONS: Lumboperitoneal shunt is an effective shunting procedure in communicating hydrocephalus.

Primary ectopic meningiomas are rare. A case of a 16-year-old male who presented with a large mass in temporofrontal region is reported. X-ray skull showed soft tissue shadow with hyperostosis of frontal and temporal bone. CT scan of brain demonstrated a markedly enhancing lesion and bony hyperostosis with no intracranial component. Total excision of tumour with hyperostotic bone was done. Patient is well without any evidence of recurrence two years after surgery. Relevant literature is reviewed.

Fifty cases of puerperal tetanus were studied. It constituted 6.66% of total cases of tetanus with overall mortality of 52% which was higher in cases with incubation period of 14 days or less, period of onset 48 hours or less, higher grades, cases with temperature more than 37.7 degrees C and patients with respiratory complications. Significantly higher mortality rate after 48 hours signifies the need of effective local control of infection to improve prognosis. Prevention, early detection and prompt treatment of respiratory complications which is the main cause of death may further reduce mortality rate in these patients.

Six hundred cases of tetanus were studied to find out incidence of respiratory complications and to evaluate factors predisposing such complications in tetanus. The incidence of complications was 41 per cent. Infants, patients of more than 40 years of age, smokers, cases with grossly contaminated injuries, short incubation period and short period of onset were more vulnerable. Patients with dysphagia, spasm, associated respiratory diseases and the patients in higher grades were also found to be more susceptible to respiratory complications.
