Abstract
The central west coast of India comprises the 720 km long coastline of Maharashtra state and houses widespread industrial zones along the eastern Arabian Sea. Sediments from seven industrial-dominated estuaries along the central west coast were studied for metal enrichment and benthic assemblages to determine sediment quality status and ecological effects in these areas. The suit of geochemical indices highlighted the contamination of sediment in the estuaries concerning heavy metals. Positive correlations of Hg with Co, Zn, Ni, Cr, and Pb indicated the source similarity and effect of anthropogenic activity. non-Metric Multidimensional Scaling (n-MDS) based on meiofaunal abundance showed a cleared separation of clusters through the gradient of heavy metal concentrations. The Canonical Correspondence Analysis (CCA) results with the Monte Carlo test signified those heavy metals influenced the meiobenthic community. Heavy metals (Cr, Ni, Zn, Cd, Pb, and Hg) were the main drivers shaping the meiofaunal community with a significant (p < 0.05) reduction in taxa richness, diversity, and evenness. Dominant meiofaunal assemblages evidence the tolerance of foraminiferans and nematodes. However, these taxa were affected by decreased abundance at impacted sites compared to other fauna. In conclusion, results demonstrated that impairment occurred in the meiofaunal community in most estuaries (except AB and KK).

Abstract
BACKGROUND : Microbiologic screening of extrapulmonary TB (EPTB) patients could inform recommendations for aerosol precautions and close contact prophylaxis. However, this is currently not routinely recommended in India. Therefore, we estimated the proportion of Indian patients with EPTB with microbiologic evidence of pulmonary TB (PTB). METHODS : We characterized baseline clinical, radiological and sputum microbiologic data of 885 adult and pediatric TB patients in Chennai and Pune, India, between March 2014 and November 2018. RESULTS : Of 277 patients with EPTB, enhanced screening led to the identification of 124 (45%) with concomitant PTB, including 53 (19%) who reported a cough >2 weeks; 158 (63%) had an abnormal CXR and 51 (19%) had a positive sputum for TB. Of 70 participants with a normal CXR and without any cough, 14 (20%) had a positive sputum for TB. Overall, the incremental yield of enhanced screening of patients with EPTB to identify concomitant PTB disease was 14% (95% CI 12–16). CONCLUSIONS : A high proportion of patients classified as EPTB in India have concomitant PTB. Our results support the need for improved symptom and CXR screening, and recommends routine sputum TB microbiology screening of all Indian patients with EPTB.

Abstract
INTRODUCTION: Testing for anti-TB drugs in small hair samples may serve as a non-invasive tool to measure cumulative drug exposure and/or adherence, as these determine treatment success. We aimed to assess how well hair assays of TB drugs predict TB treatment outcomes.METHODS: A small thatch of hair, ~30 strands, was cut from the occipital region in adults and children from a prospective TB cohort in India. Isoniazid (INH), acetyl-INH and pyrazinamide (PZA) were extracted from the hair samples and quantified using liquid-chromatography-tandem mass spectrometry. The relationship between drug concentrations in hair and time to unfavourable outcomes was assessed using Cox-proportional hazards regression models.RESULTS: A two-fold increase in hair acetyl-INH concentrations in the 264 participants in our cohort with hair assays for TB drugs indicated a lower hazard of unfavourable TB treatment outcomes (aHR 0.67, 95%CI 0.44-1.02) and TB treatment failure (aHR 0.65, 95%CI 0.42-1.01). Higher summed concentrations (a summed measure of INH and acetyl-INH) indicated a lower hazard of treatment failure (aHR 0.69, 95%CI 0.45-1.05)CONCLUSION: Hair levels of INH and its metabolite may predict TB treatment outcomes, indicating the potential utility of this measure to assess and optimise TB treatment outcomes.

Abstract
BACKGROUND: Approximately 10% of incident TB cases worldwide are attributable to alcohol. However, evidence associating alcohol with unfavorable TB treatment outcomes is weak.METHODS: We prospectively evaluated men (≥18 years) with pulmonary TB in India for up to 24 months to investigate the association between alcohol use and treatment outcomes. Unhealthy alcohol use was defined as a score of ≥4 on the Alcohol Use Disorders Identification Test-Concise (AUDIT-C) scale at entry. Unfavorable TB treatment outcomes included failure, recurrence, and all-cause mortality, analyzed as composite and independent endpoints.RESULTS: Among 751 men, we identified unhealthy alcohol use in 302 (40%). Median age was 39 years (IQR 28-50); 415 (55%) were underweight (defined as a body mass index [BMI] <18.5 kg/m²); and 198 (26%) experienced an unfavorable outcome. Unhealthy alcohol use was an independent risk factor for the composite unfavorable outcome (adjusted incidence rate ratio [aIRR] 1.47, 95% CI 1.05-2.06; P = 0.03) and death (aIRR 1.90, 95% CI 1.08-3.34; P = 0.03), specifically. We found significant interaction between AUDIT-C and BMI; underweight men with unhealthy alcohol use had increased risk of unfavorable outcomes (aIRR 2.22, 95% CI 1.44-3.44; P < 0.001) compared to men with BMI ≥18.5 kg/m² and AUDIT-C <4.CONCLUSION: Unhealthy alcohol use was independently associated with unfavorable TB treatment outcomes, highlighting the need for integrating effective alcohol interventions into TB care.

Abstract
SETTING: Pune and Pimpri-Chinchwad Municipal Corporation area, Maharashtra State, India.OBJECTIVE: To assess the sensitivity and specificity of the Xpert® MTB/RIF assay among adults with suspected pulmonary tuberculosis (PTB) and with or without diabetes
(DM).DESIGN: As part of a prospective cohort study, we screened 2359 adults presumed to have PTB with no history of TB. All individuals underwent testing for two sputum smears, culture, Xpert, glycated haemoglobin and fasting blood sugar. We calculated sensitivity and specificity
of Xpert by comparing it with TB sputum culture result as a gold standard.RESULTS: Among screened individuals, 483 (20%) were diagnosed with DM and 1153 (49%) with pre-DM; 723 (31%) had no DM. Overall sensitivity of Xpert was 96% (95%CI 95–97) and specificity was 91% (95%CI
89–93). Xpert sensitivity was significantly higher among DM group (98%) than in the ‘No DM' (95%; P < 0.01) and pre-DM (96%; P < 0.05) groups. Among sputum smear-negative individuals, Xpert sensitivity was higher in the DM group than in the No DM (92% vs. 82%;
P = 0.054) and pre-DM group (92% vs. 82%; P = 0.037).CONCLUSION: High sensitivity and specificity of Xpert underscores the need for its rapid scale up for the early detection of TB in settings with a high dual burden of TB and DM.

Abstract
BACKGROUND We compared Kaposi sarcoma (KS) risk in adults who started antiretroviral therapy (ART) across the Asia-Pacific, South Africa, Europe, Latin, and North America. METHODS We included cohort data of human immunodeficiency virus (HIV)-positive adults who started ART after 1995 within the framework of 2 large collaborations of observational HIV cohorts. We present incidence rates and adjusted hazard ratios (aHRs). RESULTS We included 208140 patients from 57 countries. Over a period of 1066572 person-years, 2046 KS cases were diagnosed. KS incidence rates per 100000 person-years were 52 in the Asia-Pacific and ranged between 180 and 280 in the other regions. KS risk was 5 times higher in South African women (aHR, 4.56; 95% confidence intervals [CI], 2.73-7.62) than in their European counterparts, and 2 times higher in South African men (2.21; 1.34-3.63). In Europe, Latin, and North America KS risk was 6 times higher in men who have sex with men (aHR, 5.95; 95% CI, 5.09-6.96) than in women. Comparing patients with current CD4 cell counts ≥700 cells/µL with those whose counts were <50 cells/µL, the KS risk was halved in South Africa (aHR, 0.53; 95% CI, .17-1.63) but reduced by ≥95% in other regions. CONCLUSIONS Despite important ART-related declines in KS incidence, men and women in South Africa and men who have sex with men remain at increased KS risk, likely due to high human herpesvirus 8 coinfection rates. Early ART initiation and maintenance of high CD4 cell counts are essential to further reducing KS incidence worldwide, but additional measures might be needed, especially in Southern Africa.

Abstract
Newcastle disease virus (NDV) strain F is a lentogenic vaccine strain used for primary vaccination in day-old chickens against Newcastle disease (ND) in India and Southeast Asian countries. Recombinant NDV-F virus and another recombinant NDV harboring the major capsid protein VP2 gene of a very virulent infectious bursal disease virus (IBDV); namely rNDV-F and rNDV-F/VP2, respectively, were generated using the NDV F strain. The rNDV-F/VP2 virus was slightly attenuated, as compared to the rNDV-F virus, as evidenced from the mean death time and intracerebral pathogenicity index analysis. This result indicates that rNDV-F/VP2 behaves as a lentogenic virus and it is stable even after 10 serial passages in embryonated chicken eggs. When chickens were vaccinated with the rNDV F/VP2, it induced both humoral and cell mediated immunity, and was able to confer complete protection against very virulent IBDV challenge and 80% protection against virulent NDV challenge. These results suggest that rNDV-F could be an effective and inherently safe vaccine vector. Here, we demonstrate that a bivalent NDV-IBDV vaccine candidate generated by reverse genetics method is safe, efficacious and cost-effective, which will greatly aid the poultry industry in developing countries.

Abstract
Newcastle disease virus (NDV) strain NDRL0901 was developed as a live vaccine candidate for control of Newcastle disease. NDV isolate KR/duck/13/07 (DK1307) of duck origin was used as the selected vaccine strain. DK1307 was passaged 6 times in chickens. Then a single clone from the chicken-adapted virus (DK1307C) was finally selected, and the vaccine strain was named NDRL0901. DK1307C and the clone NDRL0901 viruses showed enhanced immunogenicity compared to the DK1307 virus. Principal component analysis based on fusion and hemagglutinin-neuraminidase genes revealed the codon usage pattern in the dataset is distinct separating duck viral sequences and avian sequences, and passage of the duck origin virus into the chicken host causes deviation in the codon usage pattern. The NDRL0901 virus was avirulent and did not acquire viral virulence even after 7 back passages in chickens. When day-old chicks were vaccinated with the NDRL0901 virus via spray, eye drops, and drinking water, the vaccinated birds showed no clinical signs and had significant protection efficacy (>80%) against very virulent NDV (Kr005 strain) infection regardless of the administration route employed. The results indicate that the NDRL0901 strain is safe in chickens and can offer protective immunity.

Abstract
Domestic ducks are considered a potential reservoir of Newcastle disease virus. In the study, a Newcastle disease virus (NDV) isolated from a domestic duck during surveillance in South Korea was characterized. The complete genome of the NDV isolate was sequenced, and the phylogenetic relationship to reference strains was studied. Phylogenetic analysis revealed that the strain clustered in genotype I of Class II ND viruses, has highly phylogenetic similarity to NDV strains isolated from waterfowl in China, but was distant from the viruses isolated in chickens and vaccine strains used in South Korea. Pathogenicity experiment in chickens revealed it to be a lentogenic virus. The deduced amino acid sequence of the cleavage site of the fusion (F) protein confirmed that the isolate contained the avirulent motif (112)GKQGRL(117) at the cleavage site and caused no apparent disease in chickens and ducks. With phylogeographic analysis based on fusion gene, we estimate the origin of an ancestral virus of the isolate and its sister strain located in China around 1998. It highlights the need of continuous surveillance to enhance current understanding of the molecular epidemiology and evolution of the pathogenic strains.

Abstract
Infectious bursal disease (IBD) is an acute immunosuppressive disease of young chicks, caused by a double-stranded RNA virus. VP2 being the major capsid protein of the virus is an ideal vaccine candidate possessing the neutralizing epitopes. The present study involves the use of flagellin (fliC) as a genetic adjuvant to improve the immune response of VP2 based DNA vaccine against IBD. Our findings revealed that birds immunized with plasmid pCIVP2fliC showed robust immune response than pCIVP2 immunized groups. Further, challenge study proved that genetic fusion of fliC and VP2 can provide a comparatively higher level of protection against vvIBDV challenge in chickens than VP2 alone. These results thus indicate that Salmonella flagellin could enhance the immune responses and protection efficacy of a DNA vaccine candidate against IBDV infection in chickens, highlighting the potential of flagellin as a genetic adjuvant in the prevention of vvIBDV infection.

Abstract
Newcastle disease is an avian pathogen causing severe economic losses to the Indian poultry industry due to recurring outbreaks in vaccinated and unvaccinated flocks. India being an endemic country, advocates vaccination against the virus using lentogenic and mesogenic strains. Two virus strains which are commonly used for vaccination are strain F (a lentogenic virus) and strain R2B (a mesogenic virus). Strain F is given to 0-7 days old chicks and R2B is given to older birds which are around 6-8 weeks old. To understand the genetic makeup of these two strains, a complete genome study and phylogenetic analysis of the F, HN genes of these vaccine strains were carried out. Both the viral strains had a genome length of 15,186 nucleotides and consisted of six genes with conserved complimentary 3' leader and 5' trailer regions. The fusion protein cleavage site of strain F is GGRQGRL and strain R2B is RRQKRF. Although both the viral strains had different virulence attributes, the length of the HN protein was similar with 577 amino acids. Phylogenetic analysis of F, HN and complete genome sequences grouped these two strains in genotype II category which are considered as early genotypes and corroborated with their years of isolation.

Abstract
BACKGROUND Eperisone hydrochloride is a centrally acting muscle relaxant inhibiting the pain reflex pathway, having a vasodilator effect. AIMS To evaluate the efficacy and tolerability of eperisone in patients with acute musculoskeletal spasm associated with low back pain. SETTINGS AND DESIGN Prospective, randomized, double-blind, placebo-controlled, multicentric trial conducted at five tertiary care orthopedic centers across India. MATERIALS AND METHODS It was planned to enroll 240 patients of either sex between 18-60 years with acute musculoskeletal spasm (AMSP) with low back pain (LBP) due to spondylosis deformans, prolapsed disc or muscle sprain. Patients with other associated unrelated spasm conditions were excluded. Assessments were done for finger-to-floor distance (FFD), lumbar pain, Lasegue's sign, tenderness of vertebral muscles, need for rescue medication and response to therapy for efficacy and tolerability. STATISTICAL ANALYSIS Parametric data were analyzed by 't' test and ANOVA, and non-parametric data were analyzed using Mann-Whitney 'U' test and Kruskall-Wallis test. Proportions were compared using Fischer's (Chi-square) test. RESULTS Two hundred and forty patients were randomized to receive eperisone 150 mg/day in three divided doses (n=120) or placebo (n=120) for 14 days, of which 15 patients did not complete and 225 patients completed the study (eperisone, 112 and placebo, 113). Significantly greater improvement in FFD (P<0.001) from baseline on Day 14 was seen with eperisone (150.66 to 41.75) compared to placebo (138.51 to 101.60). Improvements in other parameters were greater with the eperisone group. For 89 (79.46%) patients the therapy was rated as good-excellent with eperisone compared to 43 (38.05%) patients with placebo. Nausea, abdominal pain, headache and dizziness were the common adverse events with both therapies. Rescue drug was needed by 40 (35.71%) eperisone patients and 83 (73.45%) placebo patients. CONCLUSIONS Eperisone hydrochloride was effective and well tolerated for the treatment of patients with AMSP with LBP.

Abstract
The August 2002 COM. A 21-year-old male presented with a single episode of generalized tonic clonic seizures. Radiology revealed a cystic tumor with mural nodule suggestive of a pilocytic astrocytoma. However, histopathological examination and electron microscopy revealed features of an intracerebral schwannoma. Therefore, although rare, in an intracerebral cystic lesion with mural nodule, the possibility of an intracerebral schwannoma should be entertained. This is important because this is a benign tumor with favourable response to resection.

Abstract
The phenomenon of temporal clustering of seizures is well known, but its effect on seizure localization has not been rigorously analyzed. The aim of our study was to assess electrophysiological localization during Video EEG (VEEG) monitoring in patients with intractable epilepsy demonstrating a cluster of seizures. The study was conducted on 203 intractable epilepsy patients, aged 2 to 60 years (19.96 +/- 10.87). Patients with unilateral temporal lobe epilepsy having clusters were compared with patients not having clusters, and the effect of clustering on concordance was addressed. Fully consistent localization was observed in 116 patients, partially consistent localization in 18 patients, and inconsistent localization in 19 patients. ANOVA did not reveal any significant difference in these groups (p=0.65). A total of 770 seizures recorded from 149 patients was analyzed for clustering effect. Clustering was present in 603/770 seizures pairs (78.31%). In the cluster group, 483 (80.09%) seizure pairs were concordant for seizure onset, while 98 (16.25%) were discordant and 22 (3.65%) were indeterminate. In the noncluster group, 134 (80.24%) seizure pairs were concordant for seizure onset, while 23 (13.77%) were discordant and 10 (5.98%) were indeterminate. The study found that cluster seizures occurring within an interseizure interval (ISI) less than 8 hours are independent and have the same localizing value as those seizures with longer ISIs.

Abstract
Intra-operative electrocorticography (ECoG) is useful in epilepsy surgery to delineate margins of epileptogenic zone, guide resection and evaluate completeness of resection in surgically remediable intractable epilepsies. The study evaluated 157 cases (2000-2008). The preoperative evaluation also included ictal SPECT (122) and PET in 32 cases. All were lesional cases, 51% (81) of patients had >1 seizure/day and another 1/3rd (51) had >1/week. Pre and post resection ECoG was performed in all cases. A total of 372 recordings were performed in 157 cases. Second post-operative recordings (42) and third post-operative recordings (16) were also performed. Site of recordings included lateral temporal (61), frontal (39), parietal (37), hippocampal (16) and occipital (4). 129/157 cases (82%) showing improvement on ECoG, 30/42 cases showed improvement in 2nd post resection, 8/16 showed improvement in the 3rd post-operative ECoG. 116/157 (73%) patients had good outcome (Engel I and II) at follow up (12-94 months, mean 18.2 months). Of these, 104 patients (80%) showed improvement on post-operative ECoG. 12 had good outcome despite no improvement on ECoG. The improvement in ECoG correlated significantly with clinical improvement [Sensitivity: 100% (95% CI; 96-100%); specificity: 68.3% (95% CI; 51.8-81.4%); positive predictive value: 89.9% (95% CI, 83.1-94.3%); negative predictive value: 100% (95% CI, 85-100%)]. The level of agreement was 91.72% (kappa: 0.76). Concluding, pre and post resection ECoG correlated with its grade of severity and clinical outcome.

Abstract
Giant mucoceles of the frontal sinus are a rare pathology but their recognition is important in the differential diagnosis of paediatric proptosis and fronto-orbital lesions. Four patients with giant mucoceles of the frontal sinus were retrospectively analyzed. All the patients were females in the paediatric age group presenting with massive cosmetically unacceptable bony swelling in the frontal region along with unilateral extra-axial proptosis. Radiological imaging revealed giant mucoceles of the frontal sinus with extracranial, orbital and anterior cranial fossa extension. One patient had co-existent craniofacial fibrous dysplasia. Single stage surgery was performed in three patients and two-stage surgery in one. Fronto-orbital craniotomy, removal of the posterior wall of the sinus, obliteration of the sinus and its ostium, dural repair and remodeling cranioplasty were performed. Histopathological examination revealed mucoceles in all, and co-existant fibrous dysplasia in one patient. All the patients made excellent cosmetic recoveries with complete resolution of their visual symptoms. Their clinical presentation, radiological manifestations and treatment modalities are analyzed and an extensive review of the literature is presented. Our case of giant frontal mucocele associated with fibrous dysplasia is furthermore the first such report in the existing medical literature.

Abstract
BACKGROUND The lateralising significance of unidirectional whole body turning in patients with complex partial seizures (CPS) arising from the temporal lobe was evaluated. METHODS A total of 330 patients undergoing long term video-EEG study were included. "Unidirectional whole body turning" was defined as rotation of the trunk, head, and limbs by >90 degrees and lasting >10 s. EEG correlates, MRI, and SPECT findings were compared and outcome after surgery was noted for patients with follow up data for >1 year. RESULTS Unidirectional whole body turning was observed in 13 patients with a mean age of 18+/-8 years. Concordance of the side of whole body turning with the EEG focus and MRI findings was observed in 11 of the 13 patients (84.7%) and in 26 of 28 seizures (92.8%). The six patients who underwent temporal lobectomy or resection of lesion, opposite to the direction of body turning, had good seizure outcome. CONCLUSION Unidirectional whole body turning is a new lateralising sign in temporal lobe CPS with good predictive value for epileptogenic focus contralateral to the direction of turning.

Abstract
Myxopapillary ependymomas are a benign variant of ependymomas, occurring almost exclusively in the cauda equina region. We report an extremely rare case of myxopapillary ependymoma located in the left anterior temporal lobe. A 22-year-old man is presented with intractable seizures of 2 years duration with no focal neurologic deficits. Imaging of the brain revealed a well-circumscribed heterogeneous mass in the left anterior temporal pole with no connection to the ventricles. Imaging of the spine was normal. The patient underwent surgical removal of the tumor and at follow-up 4 months after surgery, there was improvement in his memory and speech along with complete cessation of seizures. Microscopic examination revealed the tumor to be a myxopapillary ependymoma, further confirmed by histochemical and immunohistochemical stains. To the best of our knowledge, this is the first documentation of myxopapillary ependymoma at this location and consequently, the first case to clinically present as intractable temporal lobe epilepsy.

Abstract
We report two cases of lumbar spinal dermoid cysts with asymptomatic rupture and migration of free fat droplets into the central canal. No fatty droplets were seen within the lumbar subarachnoid space. The presence of fat droplets within the central canal is unusual because the central canal is rudimentary in adults. We suggest that hydromyelia secondary to tumour and specific tumour morphology might facilitate the selective rupture of dermoids into the central canal. We recommend a follow up of these patients to detect any possible intracranial migration of fat droplets and resultant complications.

Abstract
A 28-year-old man had a desmoplastic medulloblastoma in the vermis and left cerebellum. This tumor was composed of nodular, reticulin-free zones (pale islands) surrounded by densely packed, highly proliferative cells that produced a dense intercellular reticulin network. Some of the cells were heavily pigmented, and this pigment proved to be melanin. Adult age, desmoplastic nature, and melanin pigmentation are some of the rare features of this tumor that need documentation. Further, this pigment was in the primitive cells, unlike in the published cases, in which it was present in the tubular or tubulopapillary component. To the best of our knowledge, this is the first published case of desmoplastic pigmented medulloblastoma, and the patient is the oldest reported to have this tumor.

Abstract
Identification of the epileptic focus is the most important requirement for a successful surgical outcome in intractable epilepsy. Patients with normal MRI on high-resolution imaging pose a significant challenge in this regard. We tried to identify the epileptic focus using interictal / ictal SPECT and ictal EEG patterns in 14 patients with normal MRI. Rhythmic ictal onset activity helped to identify a single focus in 10 patients (71.43%). Inter ictal SPECT detected a focus corresponding to ictal EEG in 6 out of 10 patients (60%) in whom the test was performed. Ictal SPECT done in 5 patients correctly identified the focus in all patients (100%). Our data indicate that it is possible to obtain localization in patients with normal MRI using a combination of ictal EEG patterns and an ictal SPECT study.

Abstract
Tuberculous involvement of the pituitary gland is rare. We report a unique case of a composite lesion consisting of pituitary adenoma and intrasellar tuberculoma. A 24-year-old lady presented with features of acromegaly and amenorrhea. Serum growth hormone levels were found to be raised. Radiological investigations were consistent with a pituitary adenoma. Decompression of the lesion was done through trans-sphenoidal approach. Histological examination revealed a growth hormone secreting pituitary adenoma in association with a granulomatous lesion suggesting of pituitary tuberculoma. No other evidence of tuberculosis was found in the brain or spinal cord. This type of dual pathology has been reported only once in the earlier literature.

Abstract
BACKGROUND Choroid plexus papillomas (CPPs) are rare, accounting for less than 1% of all intracranial tumors in adults. However, they are relatively more common in childhood and constitute 1.5 to 4% of intracranial tumors. DESCRIPTION They are most often located in the lateral ventricle, followed by the fourth and third ventricles and, rarely, in the cerebellopontine angle. The radiological appearance of a CPP as a cyst with a mural nodule is a curiosity. Bone formation is rare in CPPs and only 6 cases have been described in the literature. Neuromelanin production is also extremely rare and only 2 cases have been reported to date. CONCLUSION In the present communication, 23 cases of CPP are analyzed and rare clinical, pathological, and radiological features are described.

Abstract
A rare case of hypothalamic hamartoma with unusual radiologic and histopathological features is described, possibly the first of its type in English literature. A 1.5-year-old female child presented with precocious puberty. MR scan of the brain revealed a pedunculated hypothalamic mass, most of which was isointense with normal brain on T1- and T2-weighted images. However, a sizeable component of the lesion was hyperintense on T1-weighted images, suggestive of adipose tissue. Microscopically, the lesion was a hamartoma composed of an admixture of neuroectodermal elements, namely glial cells, neurons, and nerve bundles along with mesenchymal elements in the form of fibroadipose tissue.

Abstract
Gliofibromas are rarely encountered astrocytic tumours comprising of astrocytic and benign fibroblastic components. They commonly occur in first two decades of life. However, the exact behaviour is not fully known and their histogenesis is also still debatable. We report three cases of gliofibroma in which we studied proliferative markers (MIB-1) and p53 protein expression. In these tumours, occurrence in adult life is in contrast to that reported in the literature. Depending upon the morphology and proliferative Labelling Index we classified these tumours into low grade (benign) and high grade (malignant/anaplastic).

Abstract
Fifty three patients underwent computerised tomography (CT) guided stereotactic biopsies from different CT defined zones of attenuation with the Leksell stereotactic apparatus from October 1993 through January 1995. Multiple lesions were seen in 16 cases and 3 of them had multiple rim enhancing lesions. Astrocytoma was the most common histological diagnosis and thalamus was the commonest site of these tumours. The overall positivity rate was 98.2%. Positive yield from the centre of the lesion, peripheral and perilesional areas was 92.1%, 54.7% and 17.6%, respectively. The definite pathological diagnosis was made in 81.1% of cases. Post-operative neurological worsening was seen in 6 patients, of which 2 recovered without any surgical treatment, in 1 patient ventriculo-peritoneal shunt was done post-biopsy whereas in another evacuation of hamatoma was done which relieved headache and vomiting while 2 patients (3.7%) died.

Abstract
A 9-year-old male child had a IV ventricular medulloepithelioma of classical histology, showing tubulopapillary and undifferentiated areas. The unusual feature, however, was the presence of melanin pigmentation in the cells, which was further confirmed by electron microscopy. So far 28 cases of medulloepithelioma have been reported in the English literature. However, none of them showed melanin pigmentation. To the best of our knowledge this is the first case of pigmented medulloepithelioma in the English literature.

Abstract
The phosphomonoesterases catalyse the hydrolysis of primary esters of phosphoric acid which help the bacteria to survive in phosphate stressed environment. Ninety-five bacterial isolates were obtained from domestic sewage and industrial effluents of gelatine and soap factories at Jabalpur on a medium enriched with phosphate and were screened for phosphatase production. The phosphatase producers were tentatively identified as Escherichia coli, Vibrio vulnificus, Aeromonas hydrophila, Staphylococcus aureus, Pseudomonas maltophilia and Micrococcus varians. The in vitro studies on the production of phosphomonoesterases by bacteria was conducted. The maximum alkaline phosphatase production was recorded on 8th day of incubation by E.coli and P.maltophilia, on 10th day of incubation by V.vulnificus while M.varians and P.maltophilia produced higher acid phosphatase on 4th and 10th day of incubation respectively. The detailed investigations were done to find out the effect of various physical and chemical factors on phosphomonoesterases activity and the optimum conditions required for enzyme activity.
