Abstract
We, in this study, report a 72-year-old woman presenting with premature osteoarthritis of the spine, the hips, the knees and the shoulders symptomatic since the age of 50 years. The initial presentation of backache led to a mistaken diagnosis of ankylosing spondylitis. Subsequent manifestation of characteristic discoloration of her sclera and overnight dark urine led to the correct diagnosis of ochronosis.

Abstract
To assess short- and long-term seizure freedom, the authors reviewed 371 patients who underwent anterior temporal lobectomy to treat pharmacoresistant epilepsy. The mean follow-up duration was 5.5 years (range 1 to 14.1 years). Fifty-three percent of patients were seizure free at 10 years. The authors identified multiple predictors of recurrence. Results of EEG performed 6 months postoperatively correlated with occurrence and severity of seizure recurrence, in addition to breakthrough seizures with discontinuation of antiepileptic drugs.

Abstract
15003 Background: Recurrent EOC is a common clinical problem and treatment is not curative. We retrospectively analyzed the data on 354 patients with recurrent EOC to determine the impact of various prognostic factors on outcome. Methods: Between August, 1989 and June, 2005, 354 patients (median age 49 years, range, 28 to 80 years) were diagnosed as recurrent EOC. 259 patients received chemotherapy alone, 44 were treated with combination of secondary debulking surgery and chemotherapy or radiotherapy. Remaining 51 (14.4%) patients had no treatment. Main types of salvage chemotherapy included- cisplatin + cyclophosphamide (CP, n = 53), CP + adriamycin (CAP, n = 68), paclitaxel + carboplatin/cisplatin (TP, n = 78). 10 factors were analyzed for survival. Results: 56.5% of patients responded to chemotherapy; complete (CR)-34.2% and partial response (PR) in 22.3% of patients. 124 (35%) patients had no response or progressive disease. 10 (2.8%) died of chemo-toxicity and in remaining 20 status was not known. Median overall survival for patients who received treatment is 19 months vs 3 months for 51 patients who did not receive treatment, p < .001. Predictors of survival were - response to salvage chemotherapy (20 vs 8 months, p < .001), treatment-free interval (>6 months vs ≤ 6 months, 23 vs 9 months p < .001), site of relapse (single vs multiple, 22 vs 16 months, p < .001), Chemotherapy regimen (CP vs CAP vs Paclitaxel + carboplatin) p < .003 on univariate analysis. Age (≤50 years vs >50 years, p = 0.02), initial stage (I vs II vs III vs IV, p = 0.079), histology (serous vs others, p = 0.849), site of relapse (vault vs others, p = 0.156) were not significant predictors. On multivariate logistic regression analysis- response to salvage chemotherapy (HR 0.21, 95% CI 0.15–0.30), treatment-free interval (HR 0.36, 95% CI, 0.20–0.64), and site of relapse (vault vs others, HR 1.22, 95% CI 0.78–1.94) attained significance among 10 factors analyzed. Conclusions: Present study confirms that all patients with recurrent EOC should receive treatment. Response to salvage chemotherapy, a longer treatment-free interval (>6 months) and single site of metastasis are predictors of significantly superior outcome. No significant financial relationships to disclose.

Abstract
15046 Background: We aimed to evaluate the role of EGFR inhibitor, gefitinib among patients with advanced & recurrent EOC to prolong progression-free survival (PFS). Methods: Between Nov. 2004 and Dec. 2005, 32 patients (median age 45 years, range 33 to 63) have been recruited. The study subjects were - (i) eleven patients with EOC stage IIIC-IV who had gross residual disease (≥1 cm) after primary debulking surgery and had achieved complete response (CR) following six cycles of paclitaxel and carboplatin (Group-I) (ii) Group II - includes 21 patients who achieved CR following salvage chemotherapy for relapsed EOC (1st relapse- 8, 2nd- 8, 3rd -3 & 4th relapse in 2 patients). All Patients received gefitinib 250 mg once daily till evidence of relapse. Patients were examined every month and toxicity (CTC version II) was recorded. Serum CA-125 was done once in 2 months and CAT scan of abdomen & pelvis at 6 monthly interval. The study was approved by Institute Ethics Committee and informed written consent was obtained from each patient before starting Gefitinib. Results: The mean duration of treatment is -5.6 months (Gp-I: 7.7 months, Gp-II: 4.5 months). Toxicity was mild, mainly in the form of skin rash & diarrhoea. Skin rash occurred in 10 patients (31.3%); Group I - 8 patients (grade IV-2, III-2, I-4) & in 2 patients in group II (grade III-1, II-1). Diarrhoea occurred in 7 patients (22%); Group I-1, group II-6) all grade I. No pulmonary or hematological toxicity was observed. Currently, 18/32 patients are on Gefitinib (mean duration of treatment 6.1 months); in 12 patients gefitinib has been discontinued due to relapse (group I- 4, Group II-10). Among 10 patients with skin toxicity (Gp I-8, Gp II-2), 6 continue to be disease-free (Group I- 5, Group II-1) compared to 12 of 22 without skin toxicity. Conclusions: Toxicity to gefitinib was mild, and limited to skin and GIT. Correlation between EGFR expression vs. response can help in identifying patients who possibly might benefit with gefitinib therapy. No significant financial relationships to disclose.

Abstract
17068 Background: Chemotherapy with platinum based doublets provides only a modest benefit in advanced NSCLC with a median overall survival (OS) of 8 months and 1-year survival rate of 33% (Schiller JH et al, N Engl J Med 2002). We performed a phase II study to determine the efficacy of thalidomide, an immunomodulatory agent with antiangiogenic activity, in combination with chemotherapy in patients with advanced NSCLC. Methods: Chemonaive patients with stage IIIB/IV NSCLC with ECOG PS≤ 2 and adequate organ function were treated with G (1000 mg/m2) and I (100 mg/m2) IV on days 1 and 8 of a 21 day cycle. Patients also received T (200 mg orally with escalation as tolerated to a maximum of 400 mg daily). Therapeutic anticoagulation with coumadin was given to the last 11 patients. Results: Twenty four patients were enrolled: median age 57 years (41–76); M:F=17:7; ECOG PS 0/1/2=13/7/3; stage IV: IIIB= 21:3 and CNS involvement: 6. Two pts died before treatment, 1 was ineligible and 1 was lost to follow up. The remaining 20 pts received a median of 4 treatment cycles (range 1–6). The regimen was generally well tolerated and the most common grade 3–4 toxicities encountered were: diarrhea (4); pneumonia (3) and thromboembolic events (3). There were no thromboembolic events after anticoagulation was initiated. Two patients (10%) experienced partial response, 14 (70%) experienced stable disease, 1 had progressive disease. Three patients (15%) were not evaluable for response due to early withdrawal. The median OS was 10.8 months (range 0.6–37+) and 1-year and 2-year survival rates were 37% and 16%, respectively. The median time to progression was 3.6 months (range 0.2–11+). Conclusions: The combination of thalidomide and chemotherapy is reasonably well tolerated and active in advanced NSCLC as evidenced by good OS and 1- and 2-year survival rates. The addition of thalidomide to a non-platinum based regimen appears to compare favorably to the results of the traditional platinum based doublets. [Table: see text]

Abstract
PURPOSE To study the incidence, clinical presentation, and the response of anti-fungals in cases of fungal endophthalmitis following open globe injury. METHODS This is a prospective study of eight cases of post-traumatic fungal endophthalmitis among 110 patients who presented to us with open globe injury between August 2003 and January 2005. Patients with panophthalmitis were eviscerated and rest received intravitreal amphotericin B. Pars plana vitrectomy along with intravitreal miconazole was given in patients with inadequate response to intravitreal amphotericin. RESULTS Two patients had panophthalmitis at the time of presentation and were eviscerated. Six different organisms were isolated from the culture of intraocular specimen of eight patients. The yield of vitreous aspirate was 87.5% and that of aqueous aspirate was 66.6%. Aspergillus sp. and Fusarium sp. were isolated in 62.5% of cases. Minimum inhibitory concentration of amphotericin B and miconazole was less than 3 microg/ml for all organisms except for Paecilomyces lilacinus and Fusarium solani, respectively. In total, 37.5% of patient had final visual acuity of 20/400 or better. CONCLUSIONS Fungal endophthalmitis is a relatively rare complication of open globe injury. The final visual outcome after fungal endophthalmitis is dismal. Aspergillus fumigatus was found to be the most virulent organism. All organisms were found to be sensitive to amphotericin B, except P. lilacinus, which was sensitive to miconazole. Repeated intravitreal injection may be required to control the infection. The virulence of the organism and the site of injury are the main determinants of final visual outcome.

Abstract
Removal of hexavalent Cr from aqueous solutions by bark of Acacia nilotica L. was studied in batch process. Different parameters of adsorption viz. effect of pH, effect of dose and effect of contact time were studied. The percentage removal of Cr (VI) from synthetic sample was found to be 89.0 and 93.1% for 1.0 mm and 0.3 mm Acacia bark carbon (ABC) respectively and 60.9% and 68.1% for 1.0 mm and 0.3 mm Acacia bark untreated (ABU) respectively, in 30 min contact time. The optimum pH for both adsorbents was found to be 2.0 and adsorption equilibrium was found to be 30 min. for both adsorbents. The adsorption process was found to follow first order rate mechanism as well as Freundlich isotherm.

Abstract
Subfrontal schwannomas are rare intracranial tumors. Most of them are associated with hyposmia/anosmia. The source of origin of these tumors is still incompletely understood. We report a 23-year-old male who presented with recurrent focal motor seizures, but had no hyposmia. The tumor was completely removed by a subfrontal approach. Relevant literature has been reviewed.

Abstract
As the number of primary and revision arthroplasties performed each year increases, the complexity of the reconstructive efforts also increases. A case of a patient with a total knee arthroplasty complicated with infection, deficient extensor mechanism, bone loss and limb shortening of 5.5 cm is reported. We describe an alternative surgical technique of reconstruction of the knee and lengthening of the limb using the Stanmore Non-Invasive Growing-Distal Femoral Prosthesis. The prosthesis had a magnetic disc attached to a gearbox. The generation of an external electromagnetic field caused the magnetic disc to rotate and lengthen the prosthesis. This reconstructive technique has not been described in the literature.

Abstract
MicroRNAs (miRNAs) are a class of small RNA molecules that regulate the stability or the translational efficiency of target messenger RNAs (mRNAs). The latency-associated transcript (LAT) of herpes simplex virus-1 (HSV-1) is the only viral gene expressed during latent infection in neurons. LAT inhibits apoptosis and maintains latency by promoting the survival of infected neurons. No protein product has been attributed to the LAT gene and the mechanism by which LAT protects cells from apoptosis is not yet known. Here we show that a miRNA encoded by the HSV-1 LAT gene confers resistance to apoptosis. Neuroblastoma cells transfected with a fragment of the LAT gene show reduced susceptibility to cell death. The anti-apoptotic function of LAT has been mapped to a region within the first exon. We have identified and characterized a microRNA (miR-LAT) generated from the exon 1 region of the HSV-1 LAT gene. The LAT miRNA was found to accumulate in cells transiently transfected with the LAT gene fragment or infected with a wild-type strain of HSV-1. A mutant virus in which a 372-nucleotide fragment encompassing the mature miRNA was deleted neither protected the infected cells from apoptosis nor generated an miRNA. miR-LAT exerts its anti-apoptotic effect by downregulation of transforming growth factor (TGF)-beta 1 and SMAD3 expression, both of which are functionally linked in the TGF-beta pathway. Our results suggest that the miRNA encoded by the HSV-1 LAT gene regulates the induction of apoptosis in infected cells by modulation of TGF-beta signalling and thus contributes to the persistence of HSV in a latent form in sensory neurons.

Abstract
BACKGROUND AND OBJECTIVES Fungal endophthalmitis is a devastating form of ocular infection and postoperative endophthalmitis following cataract surgery is the commonest form of such infection. Early diagnosis is very important for effective management of these patients. As conventional techniques take longer time and lacks sensitivity, polymerase chain reaction (PCR) for detection of fungal DNA was evaluated for early diagnosis of postoperative fungal endophthalmitis. METHODS Fifty consecutive patients with postoperative endophthalmitis (excluding proven bacterial endophthalmitis) and 25 individuals undergoing pars plana vitrectomy (PPV) of non infectious aetiologies (control group) were included in the study. Aqueous/vitreous fluids, collected from these patients, were evaluated by conventional methods including direct microscopy and culture, and by PCR for detection of fungal DNA using panfungal primers (ITS1 and ITS4) for diagnosis of fungal aetiology. RESULTS None of the controls were positive for fungal aetiology by microscopy, culture or PCR. Four patients were positive for fungal endophthalmitis by conventional method of diagnosis. PCR based method detected fungal DNA in three of these patients and in three additional patients who were negative on microscopy and culture. All six patients, who were positive for PCR, showed clinical improvement after full course of antifungal therapy. INTERPRETATION AND CONCLUSION Compared to the conventional technique, PCR for detection of fungal DNA was found to be a rapid and more sensitive method in the early diagnosis of postoperative fungal endophthalmitis.

Abstract
We report our early experience with the use of a non-invasive distal femoral expandable endoprosthesis in seven skeletally immature patients with osteosarcoma of the distal femur. The patients had a mean age of 12.1 years (9 to 15) at the time of surgery. The prosthesis was lengthened at appropriate intervals in outpatient clinics, without anaesthesia, using the principle of electromagnetic induction. The patients were functionally evaluated using the Musculoskeletal Tumour Society scoring system. The mean follow-up was 20.2 months (14 to 30). The prostheses were lengthened by a mean of 25 mm (4.25 to 55) and maintained a mean knee flexion of 110° (100° to 120°). The mean Musculoskeletal Tumour Society score was 68% (11 to 29). Complications developed in two patients; one developed a flexion deformity of 25° at the knee joint, which was subsequently overcome and one died of disseminated disease. The early results from patients treated with this device have been encouraging. The implant avoids multiple surgical procedures, general anaesthesia and assists in maintaining leg-length equality.

Abstract
Unlike commercial sex workers and patients attending sexually transmitted infection (STI) clinics, married couples are not typically targeted for HIV risk reduction programs in India. Thus, married partners of HIV-infected persons are at particularly high risk for HIV infection. Between September 2002 and November 2004, 457 HIV-1 sero-discordant, married couples were enrolled in a one-year prospective study of HIV transmission in Pune, India. The HIV incidence among uninfected partners was 1.22 per 100 person-years (95% CI 0.45-2.66), which is much lower than what has been previously reported among discordant couples in Africa. This may be due to higher rates of condom use, lower rates of STIs and higher CD4 T lymphocyte counts, among the Indian HIV sero-discordant couples.

Abstract
AIMS The study has been undertaken to document the clinicopathological features of 12 cases of chordoid meningioma, operated at All India Institute of Medical Sciences during 1996 to June 2005. METHODS Clinical information was retrieved from the records of our Neurosurgery Department. The cases were stained with H&E, Periodic Acid Schiff (PAS) with and without diastase, mucicarmine, giemsa, toluidine blue, alcian blue, reticulin and Masson trichrome. Immunohistochemistry for pancytokeratin, epithelial membrane antigen, vimentin, glial fibrillary acidic protein, MIB-1, Leucocyte common antigen (LCA), CD-3 and CD-20 was done in all cases. RESULTS The age ranged from 12-67 years (mean 34.2 years) and three of them occurred in < 18 years. Male to female ratio was 1:1.4. The duration of symptoms varied from 3.5 months to 5 years (mean 14.1 months). No systemic symptoms were noted. The location of tumor in eight cases was in the supratentorial and rest four in the infratentorial compartments. Interestingly, two cases were in intraventricular location, one in the lateral ventricle and other in the fourth ventricle. Microscopic examination showed lobulation with chordoid elements constituting > 95% of the entire tumor area in 11 of the total 12 cases. In one case, chordoid pattern constituted about 30% of the total tumor area; the rest was predominant meningothelial (60%). Mild to severe lymphoplasmacytic cell infiltrate was present in all cases. The histochemical stains showed the pattern of acidic mucin and interestingly revealed the presence of mast cells both in connective tissue stroma and epithelial cell islands. The inflammatory infiltrate was B-cell predominant. MIB-1 labeling index was low (< 2%) in all cases except two, which showed LI of 6% and 8%. Strong diffuse immunoreactivity for vimentin and focal positivity for epithelial membrane antigen was noted in all cases. CONCLUSIONS Chordoid meningiomas are predominantly tumors of young adults with predilection for supratentorial location. Intraventricular location, absence of systemic manifestations despite the presence of abundant B-lymphocytes, presence of mast cells and low MIB-1 LI are some of the interesting findings in the present series, which need documentation. Hence, larger number of cases with adequate follow-up data need to be studied further to establish the clinical significance of this variant.

Abstract
Objectives: To estimate frequency and risk factors for acute postoperative seizures (APOS) within the first week after extratemporal cortical resection (ETR) and hemispherectomy (HS) in children and to assess the predictive value of APOS on long-term seizure outcome in this group.Methods: The authors conducted a retrospective analysis of children (<18 years), who underwent ETR or HS for intractable epilepsy between 1995 and 2002. APOS features and seizure outcome after ETR or HS were obtained at 6, 12, and 24 months. Univariate logistic regression was used for risk factors of APOS and life table analysis and log rank tests for seizure outcome at 0 to 6, 6 to 12, and 12 to 24 months.Results: Of 132 patients, 34 (26%) had APOS. APOS were more frequent after ETR (26/71) than HS (8/61) (p < 0.01). APOS, irrespective of their timing, number, semiology, or other perioperative complications, were an independent predictor of poor postoperative seizure outcome at 2 years (p < 0.001). The estimated odds of postoperative Engel class I outcome in the APOS vs non-APOS categories was 0.27 (73% less likely) for 0- to 6-month, 0.22 (78% less likely) for 6- to 12-month, and 0.13 (87% less likely) for the 12- to 24-month intervals.Conclusions: Acute postoperative seizures (APOS) occur in 26% children, and the risk is higher after extratemporal cortical resection than hemispherectomy. APOS predict a poor postoperative seizure outcome at 6, 12, and 24 months. This study is useful for counseling families after epilepsy surgery. It also suggests that APOS may not be discounted as “benign” in research studies that evaluate seizure outcomes after epilepsy surgery.

Abstract
Renal transplantation is established as the best form of renal replacement therapy, but demand for kidneys exceeds supply from cadaveric donations. It is therefore important to make the best use of the pool of potential cadaveric organ donors. Donation rates are to a large extent dependent on public opinions, which may be influenced by external events. In northeast England from 1986 to 2003, there was a potential pool of 1170 brain stem-dead donors, of whom 190 (16%) could not be retrieved due to relatives' objections. From 1998 to 2003 we were referred 90 potential non-heart-beating donors, of whom relatives refused donation in 10 (11%). A major reason for not retrieving organs from a potential donor has been lack of consent from the relatives. Refusals appear to vary year by year and are consistently lower for non-heart-beating donors. This therefore raises the possibility that negative or positive media publicity plays a role in this variation.

Abstract
It is well known that the greatest risk for mortality post-renal transplant is cardiovascular death. We compared a modified cardiac risk assessment system among renal transplant patients who subsequently died versus the group that survived. There was a good correlation between the low, medium, and high scores with survival. The deceased group had significantly greater cardiovascular scores than case controls.

Abstract
A simple cardiovascular risk score used in our center to plan cardiovascular workup for renal transplantation can predict outcome in non-heart-beating donor (NHBD) renal transplantation. Patients in the higher risk group, with a score of >12 out of a maximum of 36 are likely to have a longer duration of delayed graft function, poorer glomerular filtration rate at 6 months, and inferior graft and patient survival, together with an relative rate of graft loss within 60 days of >4 (P = .053). Although a high cardiovascular risk score should not be regarded as a contraindication to NHBD transplantation, the score can be used to facilitate recipient selection.

Abstract
Filarial dance in breast lesions is a very rare entity. It is difficult to show the characteristic vigorous movement of the adult worms on static images although pulse wave Doppler and colour power Doppler have been used. Filarial dance on colour Doppler imaging has not been reported earlier to the best of our knowledge.

Abstract
BACKGROUND Clostridium botulinum neurotoxin types A, B, and E cause most cases of the paralytic disease botulism. Little is known about the epidemiology, clinical features, or microbiology of botulism type F. METHODS Cases of adult type F botulism were identified by review of data collected by CDC's National Botulism Surveillance System between 1981 and 2002. A case was either an individual whose serum or stool demonstrated type F toxin or whose stool culture yielded an organism producing toxin type F. A detailed review of cases' medical charts and laboratory data from CDC and local health departments was performed. RESULTS Between 1981 and 2002, 1,269 cases of botulism among adults and infants were reported to CDC; 13 (1%) were adult type F. The median age of type F cases was 54 years; 7 (54%) were female. None were part of outbreaks. A toxigenic Clostridium baratii was identified in 9 (69%) of 13 cases. Among 11 cases for which clinical data were available, all required mechanical ventilation for a median duration of 17 days (range, 10 to 84); 8 (73%) were intubated within 24 hours of symptom onset. All patients had nearly complete or complete quadriplegia at the nadir of neurologic dysfunction, which occurred on average on day 5. On average by day 8, improvement in neuromuscular function was noted. The median duration of acute hospitalization was 31 days (range, 20 to 60). No deaths were reported. In only one case was a possible foodborne etiology identified. CONCLUSIONS Toxigenic C baratii are the sole documented causes of type F botulism in the United States since 1981. These cases are characterized by a fulminant course with rapid progression to respiratory failure and paralysis, making early recognition and intervention critical to appropriate management.

Abstract
AIMS To prospectively evaluate by ultrasound biomicroscopy (UBM) and gonioscopy the anterior chamber angle widening following laser peripheral iridotomy (LPI) in eyes with early chronic primary angle closure glaucoma (CACG). METHODS A total of 55 eyes of 55 patients with CACG presenting with less than 180 degrees peripheral anterior synechiae (PAS) were enrolled in the study. Angles were assessed by gonioscopy (Shaffer's grading) and UBM, before and 4 weeks after LPI. The angle opening distance at 250 and 500 microm from the scleral spur (AOD 250 and AOD 500) was computed. Results were analysed using the Wilcoxon signed-rank test. RESULTS In the quadrant with LPI, the mean gonioscopy grade increased significantly from 0.45 to 1.45 (P<0.001) and the mean AOD 250 and AOD 500 increased from 38.5+/-25.9 to 83.5+/-48.4 microm (P<0.001) and 110.2+/-80.9 to 170.6+/-83.4 microm (P<0.001), respectively. The angles widened significantly in the opposite quadrant on UBM (AOD 250: 48.8+/-31.5-82.7+/-43.9 microm, P<0.001; AOD 500:117.2+/-65.5-172.2+/-81.7 microm; P<0.001), but the median gonioscopy grade remained unchanged. CONCLUSIONS LPI significantly widened the anterior chamber angle in the quadrant with LPI and the quadrant furthest away in patients of CACG with established glaucomatous damage. This change was much better appreciated by the UBM than gonioscopy.

Abstract
AIM To evaluate the effects of tamoxifen therapy on plasma lipid profile in patients of breast cancer. METHOD A total of 55 postoperative patients of breast cancer were given tablet tamoxifen 20mg orally daily for 6 months. Estimation of plasma lipid by standard method was carried out in both pre-menopausal and postmenopausal new patients of early stage breast cancer at 0 day, 3rd month and 6th months of therapy. RESULTS Suggested that in pre-menopausal and postmenopausal patient's TC and LDL-c levels were reduced significantly, whereas, TG, VLDL-c and HDL-c were not altered. Comparison of the effects of tamoxifen in pre-menopausal and postmenopausal patients on lipid profile revealed that fall in TC and LDL-c was significantly higher at both 3 and 6 months in postmenopausal patients. CONCLUSION The study demonstrates that tamoxifen to favorably alter the markers of cardiovascular risk in both pre-menopausal and postmenopausal patients of breast cancer.
