Abstract
Abstract
Aim
Assess and improve the proportion of inappropriate acute clinic referrals being made to our local ENT department via a telephone referral system with regards to nature and suitability for a junior grade doctor run clinic with senior supervision. Additionally, to make a more efficient, timely and failproof booking system with an auditable trail by transitioning to an electronic referral system.
Method
A guideline was created using based on common protocols from major Trusts within the UK which was then used to assess 101 acute clinic referrals taken from February 2021 to our local service. An electronic referral system was created, and guidelines disseminated to departments commonly making referrals to the acute clinic in anticipation for re-audit in September 2021 alongside introduction of the guideline to new doctors rotating to the specialty at induction in August.
Results
Initial audit revealed 29% of referrals were inappropriate, 50% of which were too complex, 45% were not acute and 5% were due to accidental double-bookings. Additionally, nasal fracture reviews were seen within 10 days only one third of the time, 37% of patients referred did not have a recorded contact number and 13.8% of all referrals were made with incorrect or unclear clinical information.
Conclusions
The lack of clear clinical guidance on referrals to an acute ENT service at our local centre with an outdated telephone referral system is associated with a large proportion of inappropriate referrals, delays to timely care and transcription errors potentially putting patients at risk of harm.

Abstract
Abstract
Aim
Efficient, succinct, and salient handover of current issues of surgical inpatients between doctors is an essential process which, if done ineffectively can contribute to patient harm. It was recognised that existing junior neurosurgical handover could be improved and using the Royal College of Surgeons’ and NICE guidelines for clinical handover we aimed to improve the existing handover system, improving doctor’s satisfaction with handover and patient safety.
Method
19 junior doctors on the SHO rota were surveyed to establish their perspective on the existing handover process. Based on this feedback, we redesigned handover combining national bodies’ guidance and local ideas. We resurveyed following these changes to measure improvement.
Results
Initial results showed only 36 % of junior doctors were satisfied with the existing handover procedure and only 50.5% felt the existing handover was safe. After these changes there was a 44% improvement in satisfaction with handover and a 24% improvement in the perceived safety of the handover process.
Conclusions
Handovers should be optimised to improve patient care and doctors working environment. We have improved our existing handover procedure increasing the perceived safety and doctor’s satisfaction of the handover process.

Abstract
The ACOSOG Z0011 study, heralded as a "practice changing" trial, suggested that women with T1-2 breast cancer with 1-2 SLN+, undergoing breast conservation therapy, need not be offered further ALND. However, whether these results are applicable to all women in the Indian setting, it remains debatable. A retrospective audit of all cN0 operated from 2013 to 2018 was conducted. We analyzed the percentage of additional LN positive (LN+) in the ALND group and compared it to the ACOZOG Z11 trial. Of the 2350 cN0 with EBC who underwent LAS, 687 (29%) had positive lymph nodes on final histopathology. Five hundred ninety-seven (86.9%) patients had 1-2 LN+, 40 (5.8%) patients had 3 LN+, and 50 (7.3%) had 4 or more nodes positive. Demographic features in the ACOSOG Z11 are different from those in our study, looking at ACOZOG Z11 versus our cohort-median pT 1.7 cm versus 3 cm, 45% micrometastasis versus 99.16% macrometastasis, and 28-30% grade 3 tumors versus 73.7%. In our cohort 31.82% of the 1-2 LN positive had additional LN+ on ALND. Keeping in mind the difference in clinicopathological features between our cohort and that of ACOZOG Z0011 and that 31.82% of women had additional LN+ on ALND, it may not be appropriate to apply the results of the ACOSOG Z0011 trial directly to our general population. Possibly, only a select subset of patients who match the trial population of the ACOSOG Z11 could be offered observation of the axilla and validated nomograms can be used to identify high-risk patients.

Abstract
The majority of high-risk neuroblastomas can be divided into three distinct molecular subgroups defined by the presence of MYCN amplification, upstream TERT rearrangements or alternative lengthening of telomeres (ALT). The common defining feature of all three subgroups is altered telomere maintenance; MYCN amplification and upstream TERT rearrangements drive high levels of telomerase expression whereas ALT is a telomerase independent telomere maintenance mechanism. As all three telomere maintenance mechanisms are independently associated with poor outcomes, the development of strategies to selectively target either telomerase expressing or ALT cells holds great promise as a therapeutic approach that is applicable to the majority of children with aggressive disease.Here we summarise the biology of telomere maintenance and the molecular drivers of aggressive neuroblastoma before describing the most promising therapeutic strategies to target both telomerase expressing and ALT cancers. For telomerase-expressing neuroblastoma the most promising targeted agent to date is 6-thio-2'-deoxyguanosine, however clinical development of this agent is required. In osteosarcoma cell lines with ALT, selective sensitivity to ATR inhibition has been reported. However, we present data showing that in fact ALT neuroblastoma cells are more resistant to the clinical ATR inhibitor AZD6738 compared to other neuroblastoma subtypes. More recently a number of additional candidate compounds have been shown to show selectivity for ALT cancers, such as Tetra-Pt (bpy), a compound targeting the telomeric G-quadruplex and pifithrin-α, a putative p53 inhibitor. Further pre-clinical evaluation of these compounds in neuroblastoma models is warranted.In summary, telomere maintenance targeting strategies offer a significant opportunity to develop effective new therapies, applicable to a large proportion of children with high-risk neuroblastoma. In parallel to clinical development, more pre-clinical research specifically for neuroblastoma is urgently needed, if we are to improve survival for this common poor outcome tumour of childhood.

Abstract
Abstract
Background: Women with early breast cancer routinely face a choice between breast conservation therapy and mastectomy, and assume agency through shared decision making. However, for women with lower socioeconomic power or education, barriers such as access to understandable information, involvement of family in decision making, and a decreased sense of autonomy inhibits this agency. To better empower this population, a simple to understand, online, self-administered, conjoint analysis based decision aid called “Navya Patient Preference Tool” (PPT) is developed to be used outside the physician encounter. PPT is unique in its incorporation of several psychological scales that assess potential confounders of participation in shared decision making.
Methodology: This is a pre-planned analysis of the reliability and validity of the psychological scales used in all three arms of an IRB approved randomized controlled trial to assess PPT. Women with operable node negative breast cancer eligible for BCT or MRM at one of Asia's largest academic tertiary cancer centers were eligible. PPT trial consists of an initial conjoint analysis questionnaire analyzing implicit preferences for breast conservation given to the intervention arms. The following psychological scales were given to all patients regardless of randomization: Autonomy Preference Index (API), Traditional-Egalitarian Gender Roles (TEGR), Caregiving Role, Brief Resiliency Scale (BRS), Appearances Scale, and Decisional Conflict Scale (DCS). Cronbach's alpha as a measure of internal reliability for all scales, and correlations of scores with known demographic trends as a measure of external validity are calculated.
Results: Of the 102 patients enrolled, 30 completed PPT in English, 39 in Hindi, and 33 in Marathi, (vernaculars). 69/102 were in middle and lower socioeconomic groups (Kuppuswamy Index). 53/102 had completed less than high school education. Internal reliability of all scales were high, with Cronbach's alpha above 0.7: API 0.74, TEGR 0.78, Caregiving 0.7, BRS 0.7, Appearance 0.84. DCS was highly reliable at 0.91, and is the primary outcome measure for the RCT. Correlations in the dataset met those expected in real world data, suggesting external validity. For e.g., education was inversely correlated with traditional gender roles on TEGR (R -0.4, p <0.01), and positively correlated with resilience on BRS (R 0.228, p <0.05). Individual scale items that are unrealistic were not chosen by any of the 102 respondents (e.g.,. My doctor should not participate in my medical decisions), substantiating nuanced reading. 85% of patients “Strongly Agreed” on a 1-5 Likert scale that “The survey questions were easy to understand” (mean score 1.18/5. SD 0.4).
Conclusions: Women with limited education and low socioeconomic status complete the online, self administered PPT outside of a physician encounter, with high internal reliability and external validity. Decision Aids such as Navya PPT, which account for psychosocial confounders of agency, have the potential to benefit women otherwise marginalized from shared decision making.

Abstract
Abstract
Introduction
There is no safe method of avoiding complete axillary lymph node dissection in women with breast cancer after neo-adjuvant chemotherapy. sentinel node biopsy (SNB) has had prohibitively high false negative rate. We tested low axillary sampling (LAS) and SNB performed in same patient to predict axillary lymph node status in clinically node negative women undergoing breast conservation or modified radical mastectomy after neo-adjuvant chemotherapy.
Methodology
Post neo-adjuvant chemotherapy 751 women who had no palpable axillary lymph node underwent LAS (all lymph nodes below intercosto-brachial nerve). Of these 751 women, 730 also underwent SNB by dual technique after injection of blue dye as well as radio-isotope. SN was identified within and outside axillary sampling specimen. SN as well as LAS specimens were distinctly examined for nodal metastasis. The rest of the axillary dissection was completed in all patients. Post NACT 292/751(38.9%) had residual positive lymph nodes on pathology. The identification rate, false negative rate (FNR), and negative predictive value (NPV) of SNB and LAS were compared for predicting negative axillary lymph node status.
Results
The median clinical tumor size was 5cm (1-15cm) and 533(71%) patients were N1 or N2 at presentation. The SNB identification rate was 87.1% (636 of 730), with a median of 5 nodes and node positive in 238 of 636 (37.4%). LAS identification rate was 98% (736 of 751), with a median of 7 nodes and node positive in 292 of 736 (39.6%). In all but one case, the SN was found within the LAS specimen. The FNR of SNB (blue, hot and adjacent palpable nodes) was 19.7% (47 of 238, one sided 95% upper CI 24.0) compared to LAS with FNR of 9.9% (29 of 292, one-sided 95% upper CI 12.8) (p<0.001). Comparative NPV for SNB and LAS were 89.4% and 93.9% respectively. If SNB was confined to blue/hot node excluding adjacent palpable nodes, FNR was 31.6% (74 of 234, 95% upper CI 36.6).
Conclusions
LAS is superior to SNB in identification rate, FNR and NPV in predicting node negative axilla post-neoadjuvant chemotherapy. LAS can be safely used to predict negative axilla with less than 10% chance of leaving residual disease.

Abstract
BACKGROUND Recent breast cancer treatment guidelines recommend that higher-risk premenopausal patients should receive ovarian function suppression (OFS) as part of adjuvant endocrine therapy. If chemotherapy is also given, it is uncertain whether to select concurrent or sequential OFS initiation. DESIGN AND METHODS We analyzed 1872 patients enrolled in the randomized phase III TEXT and SOFT trials who received adjuvant chemotherapy for hormone receptor-positive, HER2-negative breast cancer and upon randomization to an OFS-containing adjuvant endocrine therapy, initiated gonadotropin-releasing-hormone-agonist triptorelin. Breast cancer-free interval (BCFI) was compared between patients who received OFS concurrently with chemotherapy in TEXT (n = 1242) versus sequentially post-chemotherapy in SOFT (n = 630). Because timing of trial enrollment relative to adjuvant chemotherapy differed, we implemented landmark analysis re-defining BCFI beginning 1 year after final dose of chemotherapy (median, 15.5 and 8.1 months from enrollment to landmark in TEXT and SOFT, respectively). As a non-randomized treatment comparison, we implemented comparative-effectiveness propensity score methodology with weighted Cox modeling. RESULTS Distributions of several clinico-pathologic characteristics differed between groups. Patients who were premenopausal post-chemotherapy in SOFT were younger on average. The median duration of adjuvant chemotherapy was 18 weeks in both groups. There were 231 (12%) BC events after post-landmark median follow-up of about 5 years. Concurrent use of triptorelin with chemotherapy was not associated with a significant difference in post-landmark BCFI compared with sequential triptorelin post-chemotherapy, either in the overall population (HR = 1.11, 95% CI 0.72-1.72; P = 0.72; 4-year BCFI 89% in both groups), or in the subgroup of 692 women <40 years at diagnosis (HR = 1.13, 95% CI 0.69-1.84) who are less likely to develop chemotherapy-induced amenorrhea. CONCLUSION Based on comparative-effectiveness modeling of TEXT and SOFT after about 5 years median follow-up, with limited statistical power especially for the subgroup <40 years, neither detrimental nor beneficial effect of concurrent administration of OFS with chemotherapy on the efficacy of adjuvant therapy that includes chemotherapy was detected.

Abstract
BACKGROUND Current evidence suggests that the relationship between obesity and breast cancer (BC) risk may vary between ethnic groups. METHODS A total of 1633 BC cases and 1504 controls were enrolled in hospital-based case-control study in Mumbai, India, from 2009 to 2013. Along with detailed questionnaire, we collected anthropometric measurements on all participants. We used unconditional logistic regression models to estimate odds ratios (ORs) and 95% confidence interval (CI) for BC risk associated with anthropometry measurements, stratified on tumour subtype and menopausal status. RESULTS Waist-to-hip ratio (WHR) of ≥0.95 was strongly associated with risk of BC compared to WHR ≤0.84 in both premenopausal (OR = 4.3; 95% CI: 2.9-6.3) and postmenopausal women (OR = 3.4; 95% CI: 2.4-4.8) after adjustment for body mass index (BMI). Premenopausal women with a BMI ≥30 were at lower risk compared to women with normal BMI (OR = 0.5; 95% CI: 0.4-0.8). A similar protective effect was observed in women who were postmenopausal for <10 years (OR = 0.6; 95% CI: 0.4-0.9) but not in women who were postmenopausal for ≥10 years (OR = 1.8; 95% CI: 1.1-3.3). Overweight and obese women (BMI: 25-29.9 and ≥ 30 kg/m(2), respectively) were at increased BC risk irrespective of menopausal status if their WHR ≥0.95. Central obesity (measured in terms of WC and WHR) increased the risk of both premenopausal and postmenopausal BCs irrespective of hormone receptor (HR) status. CONCLUSIONS Central obesity appears to be a key risk factor for BC irrespective of menopausal or HR status in Indian women with no history of hormone replacement therapy.

Abstract
Abstract
Background: Adjuvant trastuzumab has improved overall survival in women with HER2 receptor positive breast cancer. However, only a small fraction (4%) of eligible patients in resource constrained settings have access to this drug. A patient assistance program of 12 weeks of adjuvant or neoadjuvant trastuzumab was thus started for those who did not have any access to trastuzumab due to financial constraints. We undertook a retrospective analysis of outcomes in women who were enrolled between January 2011 to December 2012 in this patient assistance program.
Methods: Patients received four cycles of anthracycline based chemotherapy (AC/CAF/ EC/CEF) and 12 doses of weekly paclitaxel (80mg/m2) with trastuzumab (4mg/kg loading followed by 2mg/kg) in the neoadjuvant or adjuvant setting in either sequence (anthracycline followed by taxane trastuzumab or taxane trastuzumab followed by anthracycline). Patients received adjuvant hormonal therapy depending on the hormone receptor status. The primary endpoint of this analysis was disease free survival (DFS).
Results: A total of 103 patients with HER2 receptor positive breast cancer were analysed. The median age was 46 (24-65) years, 50% were premenopausal, 60.7% had stage III disease (86.8% had node positive disease) and 37% patients had ER and or PR positive disease. Forty patients (38.8%) had breast conserving surgery while the rest had modified radical mastectomy. At a median follow-up of 34 (7-46) months the 3-year DFS and overall survival was 77.2% and 82.7% respectively. Among patients who developed recurrence one had only local recurrence, 4 had both local and distant recurrence and 11 had distant metastasis alone. Of the 15 patients who developed distant metastasis 7 had brain involvement . Symptomatic cardiac dysfunction developed in four patients, two of whom died while in the other 2 ejection fraction recovered. The results are summarised in the table.

Abstract
OBJECTIVE To compare sensitivity of pathology on imaging between referrals from primary care, physiotherapists, spinal surgeons and other secondary care providers. DESIGN AND SETTING A retrospective review of 200 consecutive magnetic resonance imaging (MRI) scans of patients' first presentations to radiology for MR lumbar scanning at a tertiary orthopaedic centre. A scan report was defined as positive if there was any evidence of neural compromise. Fisher's exact 2×2 contingency analyses were performed. RESULTS Eighty-seven (44%) scans were positive and 113 (57%) were negative. Forty-four percent of scans requested by general practitioners (GPs) were reported as positive compared with 57% of scans requested by physiotherapists. Only 40% and 20% of scans requested by specialist spinal surgeons and non-spinal team secondary care providers were positive, respectively. Physiotherapist referrals for MRI lumbar spine scans were significantly more likely to be positive compared with GPs (P=0.05), spinal surgeons (P=0.03) and others (P=0.004). CONCLUSION When appropriate, referrals via the extended physiotherapy service should be encouraged, rather than referrals directly from GPs. With appropriate training and in the appropriate clinical context, extended physiotherapy services could include inpatients and could accept outpatient referrals from other secondary care providers and not just from GPs; this would improve efficiency and reduce the workload of the radiology department and the spinal surgical unit.

Abstract
Abstract
Background- The active metabolite of Vitamin D, 1,25-dihydroxycholecalciferol (Arachitol), and D3 analogs are known to be cytotoxic, anti-proliferative, pro-apoptotic[2] and potentiate responsiveness to cytotoxic agents such as doxorubicin.[3] Depot hydroxy-progesterone caproate (DHPC) has shown benefit in disease-free and overall survival when given as a single dose prior to definitive surgery in women with node positive operable breast cancer. [1] We undertook a factorial randomized controlled phase III study to evaluate the safety and efficacy of these interventions in the neoadjuvant setting in patients with operable and locally advanced breast cancer (NCT01608451).
Methods- The study was planned as a phase III, 2×2 factorial, randomized controlled trial with a sample size of 800. Women with high-risk (clinically T2N2, T3N1-3, all M0) operable or locally advanced breast cancer who were planned for neoadjuvant chemotherapy prior to surgery, were recruited in the study. Patients were randomized (2×2) to one of the following 4 arms: patients in Arm A received standard 4 cycles of anthracycline-based neoadjuvant chemotherapy followed by surgery, those in Arm B received 500 mg of DHPC 5-14 days prior to each cycle of chemotherapy and prior to surgery, those in Arm C received intramuscular injection of 300,000 IU Arachitol, and those in Arm D received a combination of both the experimental interventions at similar time points. The primary endpoint was disease-free survival and the secondary endpoints were overall survival, pathological complete response (pCR, defined as absence of invasive cancer in breast and axillary lymph nodes in the surgical specimen), and toxicity (defined by NCI Common Toxicity Criteria). We are reporting here a planned analysis of the secondary endpoints, after recruitment of 1/6th of total sample size, on toxicity and responses in the study arms.
Results- From September 2007 to December 2010, 120 patients were recruited in the study, 27 in Arm A, 33 in Arm B, 29 in Arm C and 31 in Arm D. The arms were balanced with respect to known prognostic variables including age, clinical tumor size, clinical nodal status and ER/PR and HER2 status. Of the 120 patients, 44(36.6%) were ER &/or PR positive with HER2 negative tumors, 27(22.3%) triple negative, 41(33.9%) ER &/or PR any with HER2 positive, and receptor status was unknown in 6.6%. The rates of all grades and grade III-IV febrile neutropenia, hepatic dysfunction, renal dysfunction and dyselectrolytemia were not different between the 4 arms. Surgery was performed in 114 of 120 patients(95.0%). The pCR rates in DHPC arm vs no DHPC was 5/51(9.8%) and 5/59(8.5%) respectively. The pCR rates in Arachitol versus no Arachitol arms were 5/55(9.0%) in both arms.
Conclusions- The addition of depot hydroxy-progesterone and vitamin D3 in neoadjuvant setting were found to be safe and well tolerated. Further details of toxicity, response and the ongoing study will be presented at the Symposium.

Abstract
CONTEXT Gum guggul, a resinous exudate of the plant Commiphora mukul Engl. (Burseraceae), has been found efficacious in the treatment of bone fractures, arthritis, and hyperlipidemic disorders. OBJECTIVE The present study is an effort to explore the anti-bone-resorptive potential of the dried methanol extract of the gummy exudate of C. mukul (MECM) in ovariectomized rat model. MATERIALS AND METHODS The animals were randomly divided into five groups of equal size (n = 6). Animals in all the groups were ovariectomized except group 1, which was sham operated. Groups 3, 4 and 5 were treated with Raloxifene, MECM 250 mg/kg and MECM 500 mg/kg, respectively. The 2nd group was fed with vehicle. ASSESSMENT biochemical estimations, viz., alkaline phosphatase (ALP), tartarate resistant acid phosphatase (TRAP), serum calcium (Ca); biomechanical evaluations, and histopathological examinations. RESULTS The LD(50) of MECM was found to be > 2500 mg/kg orally. A significant elevation was observed in the ALP, TRAP, Ca and cholesterol levels in the 2nd group with a significant reduction in biomechnical strength. Groups 3, 4 and 5, showed a significant reduction in TRAP and ALP levels (p < 0.001). The Ca levels were normalized in the groups 4 and 5, while cholesterol levels dropped in group 5. The bone strength, however, was normalized in all the groups (p < 0.001) along with the histopathology. DISCUSSION AND CONCLUSION Findings suggested a significant gain in bone strength and nearly complete restoration of bone microarchitecture along with lowered levels of TRAP indicating the anti-bone resorptive potential of the extract.

Abstract
BACKGROUND This study was undertaken to document the pattern of expression of estrogen (ER), progesterone (PR) and human epidermal growth factor receptor-2 (HER2) and the usage of HER2-targeted therapy in a large tertiary care hospital in India in the year 2008. MATERIALS AND METHODS The histopathology reports of all breast cancer patients registered in the hospital in 2008 were extracted from the electronic medical record system. All the cases were immunohistochemically evaluated for estrogen and progesterone receptor status (ER and PR), and c-erbB-2 protein (HER2) expression using standard immunoperoxidase method. The use of HER2-targeted therapies was evaluated by extracting relevant information from the database of the hospital pharmacy and case charts of patients enrolled in ongoing approved trials. RESULTS A total of 2001 new patients of invasive breast cancers with available pathology reports were registered in the hospital in the year 2008. ER and/or PR expression was positive in tumors of 1025 (51.2%) patients. HER2 3+ expression by immunohistochemistry (IHC) was found in 335 (16.7%) and HER2 2+ in 163 (8.1%). The triple negative phenotype was found in 596 (29.8%) patients. An estimated 441 patients were eligible to receive HER2-targeted therapy based on their HER2 status. Of these 38 (8.6%) patients received some form of HER2-targeted therapy; 20 patients (4.5%) as part of ongoing clinical trials and 18 (4.1%) as part of routine care. CONCLUSIONS The overwhelming majority of patients eligible for HER2-targeted therapy in our institution are unable to receive it because of financial constraints and limited access to health insurance. There is a higher fraction of patients with the triple negative phenotype compared to the Western population.

Abstract
BACKGROUND Neoadjuvant chemotherapy is now the standard approach for most large breast cancers including locally advanced cancers of the breast. The majority of patients respond satisfactorily to chemotherapy with effective downsizing of tumours to consider breast conservation surgery. Pathological complete response (pathCR) is known to be a strong predictor of good outcome; however, many factors are known to influence the extent of response to chemotherapy. It has been observed that smaller the tumour, better is the response achieved in contrast to larger and locally advanced tumours where only one-third may respond well enough to merit breast conservation. Various other clinical, biological and molecular factors are also being evaluated as effective predictors of chemosensitivity. Most of these are either not easily available for all patients in developing countries or are overtly expensive and not applicable for all patients. METHODS We evaluated the clinical and pathological predictors of response to chemotherapy in 1402 women with locally advanced breast cancer. RESULTS There was a higher rate of pathCR in smaller tumours, younger women and ER-negative as well as triple negative tumours. The presence of ductal carcinoma in situ (DCIS) and lymphatic and vascular invasion (LVI) were associated with lower pathCR. CONCLUSION In the absence of ready availability of expensive molecular and genomic assays, clinical parameters and standard histopathological variables can also be useful indicators of response to neoadjuvant chemotherapy. Additionally, they can help identify those who could be eventually conserved or have a better outcome.

Abstract
Subjective Visual Disturbances are silent adversaries that appear over a period of continued exposure and arise when the visual demands of the tasks exceed the visual abilities of the user. Jewellery manufacturing activity involves precision designs, setting the metal and stones, polishing and filing which requires higher visual demand. Therefore, it is expected that the jewellery manufacturing workers may experience subjective visual disturbances. This study was taken up with the following objectives 1) To study the presence of subjective visual disturbances among jewellery manufacturing workers and compare the same with VDT operators 2) To study the effect of work exposures on subjective visual disturbances and 3) to ascertain whether subjective visual disturbances have any permanent vision related problems. The study was carried out on jewellery manufacturing workers, VDT operators and on graduate students. The symptoms of subjective visual disturbances were identified using a questionnaire developed by Sheedy (2003). Viewing distances were measured and visual angles were calculated. The eye check--ups were also carried out. The subjective visual disturbances were higher in jewellery manufacturing workers. The findings suggest that work exposure has an impact on the causation of subjective visual disturbances. No pathological conditions of the eyes were observed.

Abstract
Spray formulation can minimize pain and irritation experience during the application of conventional dosage forms. Econazole Nitrate is an active ingredient of the aerosol concentrate to be used for twice-daily application because of its long durability in the superficial layers of the fungal infected skin. The aim of this study is preliminary investigation of Econazole Nitrate spray by varying the concentrations of different constituents of the spray. The ratios of Propylene glycol (PG) and isopropyl myristate (IPM) were selected as independent variables in 22 full factorial designs, keeping the concentration of solvent, co-solvent and propellant LPG constant. Aerosol also contained Ethanol as solvent and Isopropyl alcohol as co-solvent. All ingredients of the aerosol were packaged in an aluminum container fitted with continuous-spray valves. Physical properties evaluated for the Econazole Nitrate spray included delivery rate, delivery amount, pressure, minimum fill, leakage, flammability, spray patterns, particle image and plume angle. Glass containers were used to study incompatibility between concentrate and propellant due to the ease of visible inspection. Isopropyl myristate at lower concentrate showed turbidity, while at high concentration it met the requirements for aerosol and produced Econazole Nitrate spray with expected characteristics.

Abstract
146 Background: Ductal carcinoma in situ (DCIS) identified by screening mammography accounts for 20% of breast cancer diagnoses, and microinvasion (DCIS-M) is found in 5%-10%. There are no defined treatment guidelines for palpable DCIS or DCIS-M. In the developing world wherein screening mammography is controversial due to a predominantly premenopausal population, most women with DCIS present with a palpable lump in the breast. The objective of this study was to evaluate whether disease in these patients with palpable DCIS have been treated differently from screen detected DCIS. Methods: Annually we register 3,000 new cases of breast cancer of which DCIS constitute a small fraction. Over a period of 12 years (1998-2010) we registered 71 cases of DCIS for treatment. A retrospective analysis of these was performed. Results: Of the 71 patients reviewed, 35 (49.2%) had foci of microinvasion. The median age of presentation was 49 years and mean tumor size was 2.3 cm; all presented with palpable breast lumps. Of the 36 women with DCIS alone Tsize was > 2 cm in 26 (72.2%), 14 (38.9%) had presence of comedo necrosis and 1 (2.7%) had positive lymph nodes on histopathology. Adjuvant chemotherapy was given to 4 (11.11%). Of the 35 women with DCIS-M Tsize was > 2 cm in 23 (66%), 10 (29%) had comedo necrosis (compared to 38.9% in pure DCIS p=0.45), 3 (8.5%) had positive lymph nodes, and 17 (48.6%) received chemotherapy. We compared this data to that of women treated for invasive ductal carcinoma with pTsize <2cm, at a median follow-up of 60 months, DFS for the women with DCIS was 82% (95% CI 0. 67- 0.98), for DCIS-M was 78% (95% CI 0. 59 -0.98), and that for IDC < 2cm was 83% (95% CI 0.70-0.95). Conclusions: DCIS presenting in these palpable lesions poses a clinical dilemma for the use of adjuvant therapy. Over 49.2% of the palpable DCIS showed evidence of microinvasion. We thus need to consider the role of adjuvant chemotherapy when treating women with palpable DCIS.

Abstract
Absence of breast cancer screening in India, lack of awareness in rural population, social inhibitions and poor socioeconomic status leads to a situation where a large proportion of women in India are still presenting with locally advanced breast cancer (LABC) at the time of initial diagnosis, although, there are relatively more of early stage cases detected in the metros and urban areas than maybe a decade ago. With advances in care and introduction of newer chemotherapeutic agents, it has now become feasible to offer neoadjuvant therapy with effective tumor downsizing, thus making it possible to even consider breast conservation surgery in select patients with locally advanced and unresectable disease at presentation. With reports suggesting apparent safety of the procedure, breast conservation treatment after chemotherapy is now being offered as routine care in most major centers for selective women with LABC. Multimodality therapy is the standard of care with neoadjuvant systemic therapy for all women with LABC.

Abstract
Abstract
Introduction: Early detection of breast cancer is known to have a more favourable outcome. Currently clinical breast examination and imaging modalities, primarily mammography are used for screening purposes. In India, more than 85% of the population is below the age of 50 years, wherein the sensitivity of mammography is at best 64%. Additional drawbacks of the procedure are physical discomfort and ionizing radiation dose to the patient. So newer techniques have been investigated which detect cancer induced neovascularity with digital thermal imaging. The purpose of this clinical study was to determine the efficacy of a software assisted thermal image analysis tool to distinguish between benign and malignant lesions of the breast.Methods: A prospective study was conducted in women who presented to the breast clinic with clinically or mammographically suspicious breast lesions. They also underwent thermal imaging of the breast. All mammographically suspicious lumps were subjected to histopathological confirmation. The mammography and infrared (IR) reports were compared to the histopathology.Results: In 90 women, 180 breasts were independently analyzed by both digital IR software analysis and mammography. Eighty five out of these 180 had suspicious lesions on mammography or clinical examination which were subjected to pathological confirmation. Mammography being the present diagnostic gold standard, all normal mammograms in clinically normal breast were considered as non-malignant. The sensitivity and specificity of digital thermography in detecting malignant lesions was 88.24% and 70.52% respectively with NPV of 87.01% and PPV of 72.82%. While for mammography the sensitivity and specificity were 96.25% and 96.7% with NPV of 96.7% and PPV of 96.25%. In women below 50 years of age (62/90) the sensitivity and specificity of digital thermography was 89.83% and 64.61% with NPV of 87.5% and PPV of 69.74%. Further, in the same subset no statistically significant difference was detected in the sensitivity of digital thermography to that of mammography (p = 0.7263).Conclusion: Our initial experience shows that the detection rate by digital thermal imaging is comparable to mammography in clinically palpable breast tumors. We also note that there is no significant difference in sensitivity of thermal imaging in women on either side of 50 making it a potentially testable tool for screening in younger women.

Abstract
AIMS To compare the quality of life of women with early breast cancer treated with either accelerated partial breast irradiation (APBI) or whole breast radiotherapy (WBRT). MATERIALS AND METHODS After matching for the American Brachytherapy Society criteria, the general European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and the breast cancer-specific BR23 modules were given to 48 women (23 APBI and 25 WBRT) who attended the radiotherapy clinic between May 2006 and December 2006 at Tata Memorial Hospital. RESULTS The median follow-up of patients in both groups was 3 years. The reliability and validity of the English and translated versions of the questionnaires were tested by Cronbach alpha (0.67-0.96) and Pearson's correlation for scale-scale correlation statistic (0.013-0.505). The scores for social functioning and financial difficulties in QLQ-C30 showed a trend towards a better outcome in the APBI group (P=0.025 and 0.019, respectively) and body image in BR23 was significantly better in the APBI group as compared with the WBRT group (P=0.005). When the analysis was restricted to women receiving chemotherapy in order to eliminate the confounding effect of the heterogeneous use of chemotherapy in the WBRT group, the difference in social functioning was not significant. However, financial difficulties and body image showed a trend towards a worse outcome in the WBRT group. CONCLUSION Favourable long-term results of APBI in terms of superior body image perception and lesser financial difficulties compared with WBRT need to be confirmed in larger prospective studies investigating the effect of APBI on quality of life and health economics in different ethnic groups and health care set-ups.

Abstract
BACKGROUND Targeted sentinel node biopsy has been extensively validated. It has been incorporated into standard guidelines for axillary prediction in women with clinically node-negative operable breast cancer. However, the high cost of the gamma probe and the need for radiocolloid have limited its widespread acceptance in developing countries. We aimed to validate low axillary sampling as a reliable alternative method to sentinel node biopsy in a developing country. METHODS An anatomically guided low axillary sampling removes the lower level I axillary fat with lymph nodes and the method was validated by completing axillary clearance in all women. RESULTS Three hundred fifty-five women with clinically node-negative operable breast cancer underwent validation of low axillary sampling, with lymph nodes identified in all of them. The median number of nodes identified in low axillary sampling was 5 with overall node-positivity of 32.1% (114 of 355). Ten of these 114 patients were wrongly identified as node-negative by the sampled lymph nodes, i.e. a false-negative rate of 8.8%. Further exploratory analysis showed that 6-node low axillary sampling gave an excellent false-negative rate of 1.5% with 95% sensitivity, which was comparable with the highly targeted sentinel node biopsy technique. CONCLUSIONS With an overall false-negative rate of 8.8% with 5-node low axillary sampling, and even better false-negative rate of 1.5% with 6-node low axillary sampling, axillary sampling is a low-cost technology, which is a reliable alternative to sentinel node biopsy for axillary nodal prediction in clinically node-negative breast cancer.

Abstract
Background The aim of our study was twofold. The first was to investigate the optimum position of the elbow while measuring grip endurance. The second was to investigate the optimum position of the elbow while measuring peak grip strength. The American Society of Hand Therapists advocate estimation of grip strength with the elbow flexed at 90° with the subject in the sitting position . As far as we are aware, there have been no reports in English literature regarding studies done to evaluate the position of the elbow while measuring grip endurance. Materials and methods A total of 45 healthy adults (16 males, 29 females) participated in this study. A computerised handgrip analyser was used to measure the peak strength in the non-dominant hand, followed by measurement of the grip endurance. These measurements were conducted in 90° of flexion and full extension of the elbow for each participant. Results Mean endurance in flexion was 71.0 N (SD 22.9) and in extension was 68.7 N (SD 27.4). Mean peak grip strength in flexion was 262.8 N (SD 73.1) and in extension was 264.1 N (SD 82.0). T test analysis showed no statistical significance for elbow positions for grip endurance (P = 0.67) and peak gip strength (P = 0.93). Conclusion Practical implications from this study are that grip endurance training can be undertaken with the elbow in 90° of flexion or full extension.

Abstract
The sedimentary record documenting the northward drift of India (Late Cretaceous to late Early Eocene) has recently provided important clues to the evolution, radiation, and dispersal of mammals. Here, we report a definitive Late Cretaceous (Maastrichtian) archaic ungulate (Kharmerungulatum vanvaleni genus et species nova) from the Deccan volcano-sedimentary sequences exposed near Kisalpuri village in Central India. This find has important implications for the origin and diversification of early ungulates and raises three possible paleobiogeographic scenarios: (i) Archaic ungulates may have been cosmopolitan in distribution. (ii) Kharmerungulatum might be an immigrant from Western Asia. (iii) Archaic ungulates may have originated in India.
