Abstract
INTRODUCTION The objective of this study was to study the clinical course and outcome of warfarinised patients who were hospitalised because of head trauma. METHODS 13 patients (ten males and three females; median age 69 years) who presented to the Royal Perth Hospital, Australia and who had suffered a head injury between July 1994 and June 2000 while concurrently taking warfarin, were studied. RESULTS Confusion was the commonest presenting symptom (four patients). Five patients presented after more than 24 hours of the injury. Eight patients were anticoagulated for thromboembolic disease and five for atrial fibrillation. The patients had a median injury severity score of 25 (range 1-43). The median international normalised ratio was 2.4 (range 1.8-10) on admission and 1.8 (range 1.0-10) on discharge. 11 of the 13 patients had computed tomography of the head. Intracerebral bleeding was the commonest injury (nine patients). The median length of hospital stay was six days (range 3-30). Five patients died (38.5%). CONCLUSION Warfarinised patients who sustain minor head trauma should be hospitalised for close neurological observation and should have a low threshold for performing computed tomography.

Abstract
BACKGROUND Subacute sclerosing panencephalitis (SSPE) usually has a progressive stereotypic downhill course and results in premature death. Long-term stabilization or remission is exceptional. OBJECTIVE To analyze the profile of patients with a relatively 'benign' course who survive beyond 3 years. DESIGN Descriptive analysis of 19 (16 male, 3 females)/307 (6.2%) patients with benign course who were evaluated at NIMHANS between January 1995 and December 2004. Their diagnosis was based on characteristic myoclonic jerks, elevated antibody titers against measles virus in CSF and periodic complexes in EEG. RESULTS The mean age at onset of symptoms was 11.7+/-3.9 years and mean duration of follow-up from first symptom was 5.9+/-3.1 years (3-13.8 years). Their initial symptoms were seizures (7), myoclonus (6), visual disturbances (4), behavioral changes (1) and cognitive impairment (1). These patients had varied clinical course: stabilization in different stages for 6 months to 5 years (13), remissions for 6 months to 9 years and reversal of staging with functional recovery from being bed bound to ambulant (8). Their diagnosis was often delayed. Small sample size did not permit to analyze the influence of possible disease modifying agents used in 10 patients (isoprenosine-3, amantidine-4, oral steroids-4, methylprednisolone-1, intravenous immunoglobulin-1). CONCLUSIONS Our observations suggest that SSPE may have a highly variable clinical course and warrants cautious approach for counseling at initial evaluation and while interpreting beneficial effect of disease modifying agent(s). There is a need to explore prognostic marker(s).

Abstract
CONTEXT/OBJECTIVE Bone mass is influenced by genetic and environmental factors. Recent studies have highlighted associations between maternal nutritional status during pregnancy and bone mass in the offspring. We hypothesized that maternal calcium intakes and circulating micronutrients during pregnancy are related to bone mass in Indian children. DESIGN/SETTING/PARTICIPANTS/MAIN OUTCOME MEASURES: Nutritional status was measured at 18 and 28 wk gestation in 797 pregnant rural Indian women. Measurements included anthropometry, dietary intakes (24-h recall and food frequency questionnaire), physical workload (questionnaire), and circulating micronutrients (red cell folate and plasma ferritin, vitamin B12, and vitamin C). Six years postnatally, total body and total spine bone mineral content and bone mineral density (BMD) were measured using dual-energy x-ray absorptiometry (DXA) in the children (n = 698 of 762 live births) and both parents. RESULTS Both parents' DXA measurements were positively correlated with the equivalent measurements in the children (P < 0.001 for all). The strength of these correlations was similar for fathers and mothers. Children of mothers who had a higher frequency of intake of calcium-rich foods during pregnancy (milk, milk products, pulses, non-vegetarian foods, green leafy vegetables, fruit) had higher total and spine bone mineral content and BMD, and children of mothers with higher folate status at 28 wk gestation had higher total and spine BMD, independent of parental size and DXA measurements. CONCLUSIONS Modifiable maternal nutritional factors may influence bone health in the offspring. Fathers play a role in determining their child's bone mass, possibly through genetic mechanisms or through shared environment.

Abstract
BACKGROUND Juvenile myasthenia gravis (JMG) is an uncommon disease. Unlike adults, clinical characteristics and outcomes of myasthenia gravis (MG) are not well studied in children. PATIENTS AND METHODS Case records of 77 patients with MG who were 15 years of age or less at disease onset, evaluated over a period of 34 years at the National Institute of Mental Health and Neurosciences, Bangalore, India, were reviewed. Their clinical characteristics and response to therapy was compared with 290 patients with MG onset after 15 years of age. RESULTS Median age at onset was 8 years and mean period of follow-up was 6.2 years (range 6 months to 25 years). At presentation, 30% of patients had ocular myasthenia and the rest had generalized disease. Twenty-one patients (27%) had disease confined to ocular muscles throughout the course and three had limb girdle myasthenia. Familial myasthenia was more common than adult onset disease, 10 patients had positive family history. Unlike adults, none of the patients had associated autoimmune disease. Fifty-two patients (67%) received corticosteroids, and azathioprine was added in five patients. Thymectomy was performed in 11 patients, six below the age of 15 years. Thymic histology was normal in one and showed hyperplasia in eight and thymoma in one. Four patients had crisis. At the end of follow-up, 25 patients were asymptomatic, 28 had partial improvement, and nine remained unchanged or worsened and two died. Ten patients achieved complete stable remission. CONCLUSIONS This study shows some distinctive characteristics of JMG, such as higher frequency of ocular myasthenia, benign course, better long-term outcome and lack of association of thymoma and other autoimmune disorders.

Abstract
LBA4017 Background: The aim was to establish the potential use of the third generation platinum compound, oxaliplatin (O) & the oral fluoropyrimidine capecitabine (X) in untreated patients (pts) with advanced OG cancer. Methods: After stratification for PS and extent of disease, pts with histologically confirmed adenocarcinoma, squamous or undifferentiated carcinoma of the oesophagus, oesophago-gastric junction or stomach were randomised, in a 2 x 2 design, to 1 of 4 regimens; epirubicin, cisplatin, fluorouracil (ECF), EOF, ECX or EOX. Doses E 50 mg/m2, C 60 mg/m2 & O 130 mg/m2 IV 3 weekly; F 200 mg/m2 IV daily & X 625 mg/m2 twice daily PO continuously; for 8 cycles. The primary endpoint was overall survival. With 1000 pts (250 per arm) the study had 80% power to demonstrate non-inferiority of X over F and also O over C if the upper limit of the HR 95% CI excluded 1.23 (α = 0.05) in the per protocol population. Analysis was performed using the logrank test and Cox regression analysis. Results: 1002 pts were randomised from 61 centres. Demographics were balanced, 89% were PS 0–1, 77% metastatic, median age 63 (range 22–83), 81% were male and 40% gastric primaries. Histology: adenocarcinoma in 88% and 52% poorly differentiated. 11 pts were ineligible and 27 pts were withdrawn before treatment commenced. Median follow up was 17.1 months and 850 events have occurred. There were no significant differences in response rates comparing ECF to, EOF, ECX and EOX (41%, 42%, 46%, and 48% respectively); grade 3–4 non haematological toxicity 36%, 42%, 33% and 45%; and grade 3–4 neutropaenia 42%, 30% (p = 0.008), 51% (p = 0.043) and 28% (p = 0.001) respectively. Conclusions: Capecitabine may replace 5FU and Oxaliplatin may replace Cisplatin in triplet regimens used for the treatment of advanced OG cancer. [Table: see text] [Table: see text]

Abstract
STUDY DESIGN Prospective study between 1st Jan 1995 and 31st Dec 1999. OBJECTIVE To document medical complications among subjects with Nontraumatic Spinal Cord Lesions (NTSCL) during in-patient rehabilitation. SETTING Bangalore, India. METHODS Persons with NTSCL admitted for in-patient rehabilitation were included in the study. Clinical evaluation was carried out according to The International Standards for Neurological and Functional classification of Spinal Cord Injury. Disability was quantified using Barthel index. All medical complications were documented. RESULTS A total of 297 subjects (154 men and 143 women) with NTSCL were included. The number of medical complications in each patient varied from 0 to 17 (mean=6.1+/-3.7). Common complications seen were urinary tract infections (184), spasticity (169), pain (149), urinary incontinence (147), depression (114), respiratory tract infections (101), constipation (92), pressure ulcers (89), contractures (52) and sleep disturbance (43). The number of medical complications correlated positively with duration of stay (Pearson's correlation coefficient r=0.5, P<0.01) and negatively with Barthel Index at admission (r=-0.2, P<0.05) and at discharge (r=-0.2, P<0.05). Complications were more frequent among people with tetraplegia than those with paraplegia (P<0.001). CONCLUSIONS Medical complications are frequent among subjects undergoing rehabilitation for NTSCL. Patients with severe disability at admission have more complications during rehabilitation. Conversely, individuals with more complications have greater disability at discharge.

Abstract
Protracted venous infusion 5-fluorouracil (5FU) combined with mitomycin C (MMC) has demonstrated significant activity against metastatic colorectal cancer. Owing to potential synergy based upon upregulation of thymidine phosphorylase by MMC, the combination of capecitabine and MMC may improve outcomes in irinotecan-refractory disease. Eligible patients with progressive disease during or within 6 months of second-line chemotherapy were treated with capecitabine (1250 mg m−2 twice daily) days 1–14 every 3 weeks and MMC (7 mg m−2 IV bolus) once every 6 weeks. A total of 36 patients were recruited, with a median age of 64 years (range 40–77), and 23 patients (78%) were performance status 0–1. The objective response rate was 15.2%. In all, 48.5% of patients had stable disease. Median failure-free survival was 5.4 months (95% CI 4.6–6.2). Median overall survival was 9.3 months (95% CI: 6.9–11.7). Grade 3 toxicities were palmar-plantar erythema 16.7%, vomiting 8.3%, diarrhoea 2.8%, anaemia 8.3%, and neutropenia 2.8%. No patients developed haemolytic uraemic syndrome. Symptomatic improvement occurred for pain, bowel symptoms, and dyspnoea. Capecitabine in combination with MMC is an effective regimen for metastatic colorectal cancer resistant to 5FU and irinotecan with an acceptable toxicity profile and a convenient administration schedule.

Abstract
OBJECTIVE To develop an activity questionnaire for objective and rapid assessment of maternal habitual physical activity with the aim of describing its relationship with birth size. DESIGN Prospective observational study. SETTING Six villages near Pune, Maharashtra, India. SUBJECTS Seven hundred and ninety-seven rural Indian mothers were studied after excluding abortions and termination of pregnancies, foetal anomalies, etc. METHOD Principal components analysis (PCA) was used to identify a few leading questions from an elaborate questionnaire involving 36 questions related to 14 typical maternal activities. RESULTS On the basis of high loading (>0.8), PCA identified three activities, i.e. farming, fetching water and washing clothes. Questions and sub-questions related to these activities only were considered for defining an activity score for rapid assessment. Validation of this new activity score, with the score based on the elaborate questionnaire, showed 70% sensitivity as well as specificity. New activity scores showed strong inverse relationships similar to those observed using the elaborate questionnaire, at early as well as late gestation, with neonatal head circumference (P=0.001 and 0.055) and mid-arm circumference (P=0.02 and 0.03). CONCLUSIONS Simple questionnaires, based on leading activities identified by PCA, can be as informative as longer and detailed questionnaires. This method has potential for adaptation, especially in rural communities in developing countries.

Abstract
The purpose of the study was to establish the optimal dose of capecitabine (X) to be used within a multicentre, randomised study evaluating the potential roles of oxaliplatin (O) and X in chemonaive patients (pts) with advanced oesophagogastric cancer. Two by two design was used, and pts were randomised to one of four regimens and stratified for extent of disease, performance status (PS) and centre. The treatment regimens are epirubicin, cisplatin, 5-fluorouracil (ECF), EOF, ECX or EOX. Doses: E 50 mg m−2, C 60 mg m−2 and O 130 mg m−2 i.v. 3 weekly; F 200 mg m−2 day−1 i.v. and X 500 mg m−2 b.i.d.−1 (escalated to 625 mg m−2 b.i.d.−1 after results of first interim analysis) p.o., continuously. First interim analysis was performed when 80 pts had been randomised. Dose-limiting fluoropyrimidine toxicities were stomatitis, palmar plantar erythema (PPE) and diarrhoea; 5.1% of X-treated pts experienced grade 3/4 toxicity. Protocol planned dose escalation of X to 625 mg m−2 b.i.d.−1 was instituted and a second interim analysis has been performed; results are presented in this paper. A total of 204 pts were randomised at the time of the protocol planned 2nd interim analysis. Grade 3/4 fluoropyrimidine-related toxicity was seen in 13.7% pts receiving F, 8.4% pts receiving X 500 mg m−2 b.i.d.−1 and 14.7% pts receiving X 625 mg m−2 b.i.d.−1. Combined complete and partial response rates were ECF 31% (95% CI 18.7–46.3), EOF 39% (95% CI 25.9–53.1), ECX 35% (95% CI 21.4–50.3), EOX 48% (95% CI 33.3–62.8). Grade 3/4 fluoropyrimidine toxicity affected 14.7% of pts treated with X 625 mg m−2 b.i.d.−1, which is similar to that observed with F, confirming this to be the optimal dose. The replacement of C by O and F by X does not appear to impair efficacy. The trial continues to total accrual of 1000 pts.

Abstract
BACKGROUND It often takes several days or even weeks to establish full enteral feeds (FEFs) in preterm, especially extremely low birthweight neonates because of feed intolerance related to gastrointestinal hypomotility. Clinical trials of erythromycin as a prokinetic agent in preterm neonates have reported conflicting results. AIM To systematically review the efficacy and safety of erythromycin as a prokinetic agent in preterm neonates. METHODS Only randomised controlled trials in preterm neonates (gestation < or = 37 weeks) were considered eligible for inclusion. The primary outcome was the time to reach FEFs of 150 ml/kg/day. The secondary outcomes included the incidence of erythromycin related adverse effects such as diarrhoea, cardiac arrhythmias, and hypertrophic pyloric stenosis. No restrictions were applied on the dose (low: 3-12 mg/kg/day; antimicrobial: > or = 12 mg/kg/6-8 hours) and route (oral or intravenous) and mode (prophylactic or rescue) of administration. The standard methodology for systematic reviews was followed. A subgroup analysis was pre-planned based on the dose and mode of drug administration. RESULTS Seven trials (three prophylaxis, four rescue) with various doses, routes and modes of administration, and durations of erythromycin treatment and different results were found to be eligible for inclusion in the analysis. Meta-analysis could not be performed, as specific data were either inadequate or not available. CONCLUSION The conflicting trial results may be explained by differences in dose and route and mode of administration of erythromycin and in gastrointestinal motor responses in the presence of different feeding conditions-for example, fasting v fed state, intermittent v continuous feeds. Gestational and postnatal ages during erythromycin treatment are also important.

Abstract
The purpose of this study was to determine whether epirubicin, cisplatin and infused 5FU (ECF) improves overall survival (OS) compared to 5FU, etoposide and leucovorin (FELV) in patients with previously untreated advanced biliary cancer in a prospective randomised study. Patients were randomly assigned to receive epirubicin, cisplatin and infused 5FU ECF or bolus 5FU etoposide and leucovorin (FELV). The primary end point was OS with secondary end points of objective response rate (ORR), failure-free survival (FFS), quality of life (QOL) and toxicity. In all, 54 patients were recruited with 27 randomly assigned to each arm. The median OS for ECF was 9.02 months (95% confidence interval (CI): 6.46–11.51) and FELV 12.03 months (95% CI: 9.3–14.7), P=0.2059. Objective response rates were similar for both arms: ECF 19.2% (95% CI: 6.55–39.3); FELV 15% (95% CI: 3.2–37.9), P=0.72. There was significantly increased grade 3/4 neutropenia with FELV vs ECF (53.8 vs 29.5%, respectively, P=0.020). Symptom resolution was impressive for both regimens. This is the largest reported randomised study to date in this setting. ECF did not improve OS compared to FELV, but was associated with less acute toxicity. These data suggest that chemotherapy can prolong OS and achieve good symptomatic relief in advanced biliary cancer.

Abstract
Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disease predisposed by heterozygous germline mutations in the MEN1 tumor suppressor gene. Biallelic loss of MEN1 resulting from small mutation and/or loss of heterozygosity occurs in a large tissue spectrum of MEN1 tumors or non-hereditary tumors. Mouse models of MEN1 underexpression or overexpression have also supported the tumor-suppressor effect of the MEN1 gene. Menin, the 610-amino-acid protein encoded by MEN1, is expressed ubiquitously and found predominantly in the nucleus. Sequence analyses do not reveal motifs of known function other than two nuclear localization sequences. Menin has been found to partner in vitro with a variety of proteins that comprise transcription factors, DNA processing factors, DNA repair proteins, and cytoskeletal proteins. The diverse functions of menin interactors suggest roles for menin in multiple biological pathways. Inactivation of menin switches its JunD partner from a downstream action of growth suppression to growth promotion. This is a plausible mechanism for menin tumorigenesis.

Abstract
BACKGROUND AND STUDY AIMS Colonic tuberculosis is not uncommon in developing countries. As emigration to the West increases, it is worthwhile to recall the clinical, colonoscopic, and histopathological features of this condition. PATIENTS AND METHODS The clinical, colonoscopic and histopathological findings were evaluated in 43 patients with colonic tuberculosis. RESULTS Abdominal pain, weight loss, diarrhea, fever, and a lump in the abdomen were the commonest symptoms. Extraintestinal tuberculosis was present in 11 patients (26 %). Colonoscopy revealed ulcers in 30 patients (70 %), nodules in 24 (56 %), a deformed cecum and ileocecal valve in 17 (40 %), strictures in 10 (23 %), polypoid lesions in six (14 %), and fibrous bands forming mucosal bridges in three (7 %). The cecum and ascending colon were the commonest sites involved. Segmental tuberculosis was seen in six of the 32 patients (19 %) in whom full-length colonoscopy could be performed. Two or more sites were involved in 19 patients (44 %). Histopathology revealed well-formed granulomas in 23 patients (54 %). Fourteen of the above patients (61 %) had caseation and 11 (48 %) had confluence of the granulomas. Acid-fast bacilli were present in the biopsies from two patients (5 %). Ill-formed granulomas were seen in seven patients (16 %) and chronic inflammatory changes in 13 (30 %). Despite the various histopathological findings, all of the patients responded to antitubercular treatment and continued to remain asymptomatic during the follow-up period. CONCLUSIONS Colonoscopy with biopsy is a useful method for diagnosing colonic tuberculosis. Even in the absence of the classic histopathological features, a therapeutic trial may be indicated in a given clinical and colonoscopic setting. Follow-up is essential.

Abstract
BACKGROUND The purpose of this study was to assess the efficacy and safety of ISIS 3521, an antisense phosphorothioate oligonucleotide to protein kinase C alpha in patients with relapsed low-grade non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS Twenty-six patients received ISIS 3521 (2 mg/kg/day) as a continuous infusion over 21 days of each 28-day cycle. RESULTS The median age of the patients was 53 years (range 37-77). Histological subtypes were low-grade follicular lymphoma (n = 22) and B-cell small lymphocytic lymphoma (n = 4). Twenty-one (81%) had stage III/IV disease. The median number of previous lines of chemotherapy was two (range one to six). A total of 87 cycles of ISIS 3521 were administered. Twenty-three patients were assessable for response. Three patients achieved a partial response. No complete responses were observed. Ten patients had stable disease. Grade 3-4 toxicity was as follows: neutropenia (3.8%) and thrombocytopenia (26.9%). CONCLUSIONS ISIS 3521 has demonstrated anti-tumour activity in patients with relapsed low-grade NHL. There may be a potential role for this agent in combination with conventional chemotherapy for advanced low-grade lymphoma, and further trials are warranted.

Abstract
Advances in neonatal management have led to considerable improvement in newborn survival. However, early (<72 hours) and late (>72 hours) onset systemic infections, both bacterial and fungal, remain a devastating complication and an important cause of morbidity and mortality in these babies. Most neonatal fungal infections are due to Candida species, particularly Candida albicans. The sources of candidiasis in NICU are often endogenous following colonization of the babies with fungi. About 10% of these babies get colonized in first week of life and up to 64% babies get colonized by 4 weeks of hospital stay. Disseminated candidiasis presents like bacterial sepsis and can involve multiple organs such as the kidneys, brain, eye, liver, spleen, bone, joints, meninges and heart. Confirming the diagnosis by laboratory tests is difficult and a high index of suspicion is required. The diagnosis of fungemia can be made definitely only by recovering the organism from blood or other sterile bodily fluid. Amphotericin B continues to be the mainstay of therapy for systemic fungal infections but its use is limited by the risks of nephrotoxicity and hypokalemia. Newer formulations of amphotericin B, namely the liposomal and the lipid complex forms, have recently become available and have been reported to have lesser toxicity. More recently Indian liposomal Amphotericin B derived from neutral lipids (L-Amp-LRC-1) has shown good response with less toxicity. A clinical trial with this preparation has shown to be safe and efficacious in neonatal fungal infections. Compared to other liposomal preparations, L-Amp-LRC-1 is effective at lower dose and is less expensive drug for the treatment of neonatal candidiasis.
