Abstract
ABSTRACTA PbTiO3(001) film grown on MgO(001) by pulsed laser deposition is examined as an example to demonstrate the applications of the domain stability map for epitaxial perovskite films which shows regions of stable domains and fractions of domains in a polydomain structure. X-ray diffraction studies indicate that the film has a …c/a/c/a… domain structure in a temperature range of °C to 400°C with the fraction of c-domains decreasing with increasing temperature. These experimental results are in excellent agreement with theoretical predictions based on the stability map.

Abstract
BACKGROUND Determination of RHD zygosity is important for the prevention of haemolytic disease of foetus and neonate. There is no data from India regarding the prevalence of RHD genotypes. OBJECTIVES We conducted this study to investigate RHD zygosity in phenotypically RhD positive (RhD+) Indians. We have also investigated the utility and concordance of two different genotyping techniques. METHODS Hundred serologically RhD+ Indians were genotyped at the RHD gene using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and polymerase chain reaction-sequence-specific primer (PCR-SSP) techniques. RESULTS Of the 100 RhD+ individuals, 26 (25%) were D heterozygous by both methods and 74 (71·2%) were D homozygous. There was no discordance in the results from the two techniques. CONCLUSION At least 25% of RhD+ Indians are heterozygous at the RHD gene. Both the genotyping techniques were equally robust and their complete concordance indicates RHD deletion as the main mechanism underlying RhD negativity in Indians.

Abstract
Background: Despite earlier studies demonstrating in vitro propagation of solid tumour cancer stem cells (CSCs) as non-adherent tumour spheres, it remains controversial as to whether CSCs can be maintained in vitro. Additional validation of the CSC properties of tumour spheres would support their use as CSC models and provide an opportunity to discover additional CSC cell surface markers to aid in CSC detection and potential elimination. Methods: Primary tumour cells isolated from 13 surgically resected colon tumour specimens were propagated using serum-free CSC-selective conditions. The CSC properties of long-term cultured tumour spheres were established and mass spectrometry-based proteomics performed. Results: Freshly isolated CD133+ colorectal cancer cells gave rise to long-term tumour sphere (or spheroids) cultures maintaining CD133 expression. These spheroid cells were able to self-renew and differentiate into adherent epithelial lineages and recapitulate the phenotype of the original tumour. Relative to their differentiated progeny, tumour spheroid cells were more resistant to the chemotherapeutic irinotecan. Finally, CD44, CD166, CD29, CEACAM5, cadherin 17, and biglycan were identified by mass spectrometry to be enriched in CD133+ tumour spheroid cells. Conclusion: Our data suggest that ex vivo-expanded colon CSCs isolated from clinical specimens can be maintained in culture enabling the identification of CSC cell surface-associated proteins.

Abstract
OBJECTIVE This study aims to highlight the clinical features, investigations and treatment outcome of retroperitoneal teratomas (RPT) in children. MATERIALS AND METHODS A total of eight patients (six males and two females, age range between 6 months-10 years) of RPT admitted in the department of Paediatric Surgery, PGIMS, Rohtak, between 1996-2008, were studied. The patients were investigated with hematology, x-ray, ultrasound, and computerised tomography (CT) of abdomen and serum alpha-fetoprotein levels in pre and postoperative period. All patients underwent complete surgical resection. In one patient, the tumour had malignant component (yolk sac) and was given postoperative chemotherapy. Postoperative follow-up included serum alpha-fetoprotein in addition to clinical examination and radiological assessment to detect recurrences. RESULTS The tumours were located on both sides in almost equal proportion (four on right, three on left, and one bilateral]. All tumours could be excised completely preserving the kidneys in all patients. But in one patient injury to inferior vena cava (IVC) occurred which was repaired successfully. Majority (7 out of 8) were histological benign, and in one yolk sac tumour was malignant component which needed chemotherapy. All children were on follow-up and one patient with malignancy lost to follow-up after three cycles of chemotherapy. In rest there was no tumour recurrence. CONCLUSION RPT are rare paediatric neoplasms. As majority are benign, a complete excision preserving the kidneys, is usually curative. Serum alpha-fetoprotein is a reliable method of assessing recurrence. Malignancy in the tumour may warrant further chemotherapy.

Abstract
BACKGROUND Inflammation of the airways in asthma is associated with the production of cysteinyl leukotrienes (cysLT), prostaglandin (PG)E(2), 8-isoprostane, nitric oxide and other mediators. However, the relationship between asthma severity or eosinophilic inflammation and the concentrations of mediators in sputum is unclear. OBJECTIVE To assess sputum PGE(2), cysLT, 8-isoprostane and nitrate concentrations, as well as urinary leukotriene (LT)E(4) and 9alpha,11beta-prostaglandin (PG)F(2) concentrations, in patients with differing severities of asthma and eosinophilic or non-eosinophilic airway inflammation. METHODS Inflammatory cells in sputum were assessed in 12 patients with mild, 14 with moderate and 12 with severe persistent asthma, as well as in 13 control subjects. Asthmatic patients were categorized into those with eosinophilic or non-eosinophilic airway inflammation. Sputum PGE(2), cysLT and 8-isoprostane, and urinary LTE(4) were extracted on immunoaffinity sorbents, and the concentrations of all mediators were measured using enzyme immunoassays. Sputum nitrate concentrations were measured on a chemiluminescence analyzer. RESULTS Sputum PGE(2) concentrations were higher in both moderate (1710 pg/mL) and severe asthmatic (1590 pg/mL) compared with control subjects (827 pg/mL) (P<0.05). CysLT concentrations were higher in moderate asthmatic compared with control or severe asthmatic subjects (P<0.05). Sputum PGE(2) concentrations were lower in patients with eosinophilic (1180 pg/mL) compared with non-eosinophilic airway inflammation (2520 pg/mL) (P=0.02). In contrast, sputum cysLT and urinary LTE(4) concentrations were higher in those with eosinophilic airway inflammation (P<0.05). Forced expiratory volume in 1 s was inversely correlated with sputum eosinophils in all asthmatic patients (r(s)=-0.5, P=0.002). There were no significant differences in sputum 8-isoprostane or nitrate concentrations. CONCLUSIONS Increased airway concentrations of PGE(2) are consistent with the hypothesis that PGE(2) has a bronchoprotective and anti-inflammatory role in patients with more severe asthma. A reduced PGE(2) to cysLT ratio in the airways may adversely affect lung function and contribute to persistence of symptoms and airway remodelling in patients with eosinophilic airway inflammation.

Abstract
e22164 Background: Breast cancer incidence is increasing throughout Asia. However, the characteristics of Asian breast cancer are not always well understood due to the limited availability of local data and their inadequate inclusion in global literature databases. Effective breast cancer treatment in this region requires a better understanding of Asian breast cancer biology, including ErbB2 status. Methods: We performed a literature search in seven Asian countries on breast cancer studies in which tumour ErbB2 overexpression was assessed. The keywords erbB2 OR HER2 OR ErbB-2 OR HER-2 AND breast cancer AND (country) were used to search PubMed, international and local conference abstracts and local-language journals from the year 2000 onwards. Where available, we selected up to five representative studies from each country on the basis of population size, multi-institution patient populations, institution reputation and journal impact factor. We excluded studies containing only mRNA, serum, or cell line data or those conducted on biased populations or in western countries on Asian populations. Results: ErbB2 data from 26 Asian breast cancer studies are summarized in the table . The mean or median age of the study populations ranged from 46–56 years, with one exception. In most studies that evaluated tumour ErbB2 and hormone status, ErbB2 over-expression correlated negatively with ER positivity. Conclusions: The larger studies in particular confirm that the proportion of ErbB2-positive breast cancer in Asia is generally similar to the 20–30% reported for western women. Definitions of ErbB2 positivity using IHC vary between institutions and FISH is not routinely performed in several Asian countries. This may contribute to the fact that reliable, representative data on breast tumour ErbB2 status is scarce in Malaysia, the Philippines, India and Thailand. The increased availability of accurate ErbB2 testing and data would aid improved treatment of ErbB2-positive breast cancer in these countries. [Table: see text] [Table: see text]

Abstract
e19566 Background: We retrospectively analysed records of the Patients visiting the pathology department of Sir Ganga Ram Hospital, New Delhi a super-speciality hospital, between February 2007- February 2008. Out of a total of 16,500 cases, NHL was reported in 154 (0.93%)cases. The median age was 52 yrs and the no. of male patients were 104 and female were 50 making M:F = 2:1. The type of NHL was B-Cell type (CD-20+ve) in 132(85%) and T-Cell type (CD 3+ve) in 22 (15%) cases. Out of 154 patients, 77 were nodal and 77 were extra nodal. Additional features - HIV positivity in 2 patients, autoimmune haemolytic disease in 1 patient and thalessemia major in 1 patient. In extra-nodal group of NHL patients the no. Of male and female patients were 55 & 22 respectively (M:F=2.5:1). Out of 77 extra-nodal cases, 31(20%) were GIT NHL (Stomach -16, Colon-8, Ileum-4, and Duodenum-3) and out of the rest 46 extra-nodal cases the site of origin was - head & neck-14, skin n soft tissues -8, primary CNS-6, testicular-4, para-spinal- 3, breast mass-3, perinephric-2, bones-2 and 1 each in cervix, lung mass, liver and cervical plexus. Methods: A detailed analysis of 31 GIT NHL cases was carried out. 28 out of 31 were B-Cell type and 3 were T-Cell type. 26 out of 31 were diffuse large cell variety, 2 were mixed small & large cell variety and 1 MALT variety. In 2 patients the type of lymphoma could not be ascertained. Bone marrow infiltration was present in 2 out of 31 cases of GIT Lymphoma. Surgery was carried out in 15 of 31 GIT NHL cases and these were arising from Colon, Ileum and Duodenum. No surgery was performed in patients with stomach lymphoma. Results: Of all the extra-nodal cases chemotherapy was given to 39 patients - R-CHOP = 20 patients, CHOP = 13 patients, high dose MTX in primary CNS NHL = 6 patients. CR was achieved 16 out of 20 R-CHOP patients (80%), 8 out of 13 CHOP Patients (61 %) and 4 out of 6 high dose MTX patients (66%). No significant financial relationships to disclose.

Abstract
e11533 Background: A close or positive margin after breast cancer surgery is an important risk factor for local recurrence. A significant percentage of breast cancer patients need additional surgeries to obtain clear margins. This study evaluated the impact of residual cancer (RC) found upon subsequent operations on the outcome of the patients with localized breast cancer. Methods: Under IRB approved protocol, we retrospectively analyzed data on 573 patients with stage I-IIIA breast cancer treated at our institution during 1994–2004. 202 patients had complete tumor removal at single procedure with clear margins, 319 patients had subsequent surgery due to initially compromised margins and 52 patients with compromised margins did not have second surgery. Cox Proportional Hazard regression test was performed to evaluate the effect of RC found on subsequent surgery on distant recurrence (DR) and disease specific survival (DSS). Results: Median follow-up was 5.4 years. Among 319 patients who underwent second surgery, 57.7% did not have any RC; 13.1% had in situ RC and 29.2% had invasive RC. 12.9% (74/573) patients had DR. The risk of DR was higher in patients with RC found upon second surgery compared to those who had single procedure breast cancer removal (22.6% vs. 9.9%; HR 2.4, 95% CI 1.3–4.4, p=0.006). Similarly, finding of RC was a significant predictor of DSS (80.6% vs.92.6%; HR 2.9, 95% CI 1.4–5.7, p=0.003). Multivariate analysis revealed that tumor size above 5 cm, lymph nodes involvement and grade III were significant predictors of DR and DSS along with invasive RC found during subsequent surgeries. Delay in adjuvant chemotherapy due to need for subsequent surgeries strongly correlated with earlier DR in patients with invasive RC found on subsequent operations (rS = - 0.55, p = 0.019, two-tailed). Conclusions: Invasive residual carcinoma found during subsequent surgery after initial compromised margin is an important prognostic factor for DR and DSS, even after clear margins are eventually achieved. No significant financial relationships to disclose.

Abstract
Although diaphragmatic paralysis is a rare recognized complication of chest tube malposition, Chilaiditi's sign occurring as a result of this complication has never been reported in literature to the best of our knowledge. We describe one such case, which had an interesting clinical sequence of events and radiographic findings and suggest that the medial end of the chest tube should be positioned at least 2 cm from the mediastinum on the frontal chest radiograph to avoid these complications.
