Chordoma: 6 years' experience at a tertiary centre.

Nine patients with a histologically proven diagnosis of chordoma seen at the Department of Radiation Oncology, Maulana Azad Medical College and Lok Nayak Hospital between January 1999 and December 2004 were retrospectively reviewed with respect to age, sex, presentation, location of tumour, treatment, response, recurrence, metastasis and follow up. Chordoma constituted 0.07% of total cancer cases registered over 6 years. Out of nine patients, eight were males and one was female with median age at time of diagnosis 52 years (range 34-68 years). All had sacrococcygeal lesions except one who had a spheno-occipital lesion. Seven patients had undergone either subtotal or gross total resection whereas only biopsy had been carried out in two of them. All patients received radiation therapy, seven in a postoperative setting and two for palliation. Follow-up period ranged from 2 to 50 months. Four patients died--the first after fourth fraction of radiation, second after 10 days of treatment, third of progressive lesion in sphenoidal region despite resection and radiation and fourth of local recurrence in the sacrococcyx. One patient developed distant metastases in the lungs and subcutaneous tissue over the scalp along with local recurrence; he is still alive. Two patients are locally free of disease whereas the other two were lost to follow up. The present analysis was undertaken to review our institutional experience with an aim to provide a practical approach to these tumours. In this report, these cases are discussed and the published works have been reviewed for the optimal management of patients with chordoma.

Mixed streams wastewater treatment using adsorption.

Mixed samples prepared from known pure solutes are reported to have synergetic efforts with respect to single solute and multi-solute adsorption. Attempt is made to extend the theory of enhancement ratios to the mixed stream wastewater samples collected from dyes manufacturing industries. Synergetic effect of the multi-solutes as well as of mixture of adsorbents is observed for mixed streams of wastewater samples, containing a number of pollutants, on given inexpensive adsorbents. The Rathi Puranik model developed for single wastewater streams can be extended to the mixed stream wastewater samples using the rate of COD reduction prediction. The concept of average apparent enhancement factor is discussed.

Primary intracranial chondrosarcoma--a case report.

Intracranial malignant cartilaginous tumors, not arising from the skull bones are a rare phenomenon, and few cases have been reported till date in literature. We hereby describe one such case treated by us.

Stromal sarcoma of the breast: a case report.

Malignant mesenchymal tumours of the breast are rare neoplasms. Their incidence varies from 1%-3% of all malignant breast tumours (1). Stromal sarcoma of the breast is an extremely uncommon tumour (2). We present a rare case of advanced stromal sarcoma of the breast successfully managed with radical surgery and radiotherapy.

Growth patterns in breastfed babies during first six months of life.

Growth of exclusively breastfed 126 normal newborns in urban slums and those delivered at Nehru Hospital, Medical College, Gorakhpur were studied upto six months of age. The average weight of both boys and girls was almost equivalent to the 25th percentile of NCHS standard upto 3 months but fell below these standards thereafter. The average length in both boys and girls was between 25th and 50th percentile of NCHS data. The average head circumference in girls was between 25th and 50th percentile of NCHS data at all ages but in boys it was between 10th and 25th percentile at 4, 5 and 6 months of age. The average weight, length, head and chest circumference in both boys and girls were comparable to ICMR standards. The observations indicate that exclusive breastfeeding should be promoted for adequate growth of infants during first six months of life.

Pregnancies in adolescents: fetal, neonatal and maternal outcome.

We studied the perinatal morbidity and mortality among adolescent pregnancies in the semi-urban population of Gorakhpur. The number of eligible couples (females 15-44 yrs) were 24,000. Out of 430 adolescent married girls, 242 (56.3%) became pregnant during the study period. Nineteen (7.8%) of adolescent pregnancies were in the maternal age group less than 15 years and 110 (45.5%) and 113 (46.7%) pregnancies were in the age group 15-17 yrs and 17-19 yrs, respectively. The incidence of low birth weight babies was 67.3% of all live births. Infections during neonatal period, congenital anomalies and birth injuries were seen in 21.6, 8.6 and 13.1% newborns, respectively. Neonatal mortality rate was 136.2/1000 live births. Three adolescent mothers died during pregnancy or puerperium due to causes related to pregnancy. The incidence of LBW, neonatal and maternal morbidity and mortality associated with adolescent pregnancies were significantly higher.

JE virus encephalitis: 1988 epidemic at Gorakhpur.

Gorakhpur region experienced the most serious outbreak of Japanese encephalitis (JE) in 1988 in which 875 children were admitted in the Department of Pediatrics, BRD Medical College, Gorakhpur. Children between 7-10 years age group constituted half (49.3%) of these cases, convulsions (83.8%), altered sensorium (78.2%), headache (68.8%) and hypertonia (77.0%) were the main presenting features. IgM against JE virus was demonstrated in 18/25 CSF and 27/53 sera collected from these children. Significant titres of HI antibodies against JE were present in 498/670 patients. Patients were managed symptomatically. Dexamethasone and dopamine were given to only 137 (15.7%) children admitted with shock and peripheral circulatory failure. Almost a third (31.8%) of the patients expired, 51.4% recovered completely and 10.7% recovered partially. Corticosteroids did not improve the outcome. Twenty four patients had recurrence of symptoms after excellent recovery from acute attack of whom two died and 5 developed neurological deficits.
