Abstract
AIMS To evaluate the incidence and pattern of contralateral nodal relapse (CLNR), contralateral nodal relapse-free survival (CLNRFS) and risk factors predicting CLNR in well-lateralised oral cavity cancers (OCC) treated with unilateral surgery and adjuvant ipsilateral radiotherapy with or without concurrent chemotherapy. MATERIALS AND METHODS Consecutive patients of well-lateralised OCC treated between 2012 and 2017 were included. The primary endpoint was incidence of CLNR and CLNRFS. Univariable and multivariable analyses were carried out to identify potential factors predicting CLNR. RESULTS Of the 208 eligible patients, 21 (10%) developed isolated CLNR at a median follow-up of 45 months. The incidence of CLNR was 21.3% in node-positive patients. CLNR was most common at level IB (61.9%) followed by level II. The 5-year CLNRFS and overall survival were 82.5% and 57.7%, respectively. Any positive ipsilateral lymph node (P = 0.001), two or more positive lymph nodes (P < 0.001), involvement of ipsilateral level IB (P = 0.002) or level II lymph node (P < 0.001), presence of extranodal extension (P < 0.001), lymphatic invasion (P = 0.015) and perineural invasion (P = 0.021) were significant factors for CLNR on univariable analysis. The presence of two or more positive lymph nodes (P < 0.001) was an independent prognostic factor for CLNR on multivariable analysis. CLNR increased significantly with each increasing lymph node number beyond two compared with node-negative patients. CONCLUSION The overall incidence of isolated CLNR is low in well-lateralised OCC. Patients with two or more positive lymph nodes have a higher risk of CLNR and may be considered for elective treatment of contralateral neck.

Abstract
CONTEXT Early detection of oral premalignancy and malignancy using simple screening aids play a promising role in curbing the disease. AIM The primary aim of this study is to evaluate and the secondary aim of this study is to compare the cytomorphometry and cellular atypia in keratinocytes obtained from oral rinse and conventional exfoliative cytology in normal oral mucosa and clinically diagnosed oral leukoplakia. MATERIALS AND METHODS The study comprised of 55 clinically diagnosed cases of leukoplakia and 55 age and sex matched normal controls. Smears were prepared using oral rinse technique followed by the conventional exfoliative cytology. Papanicoloau stained smears were evaluated for atypia and subjected to image analysis. Based on the presence of atypia they were further divided into three groups (Group 1-cases with atypia, Group 2-without atypia and Group 3-normal controls) and analyzed. Statistical analysis used one-way analysis of variance followed by Tukey Honestly Significant Difference test for intergroup analysis and unpaired students t-test to compare the two methods. RESULTS Smears prepared with both methods demonstrated atypia in 18 cases. The cellular diameter and cellular area (CA) were progressively increased from Group 1 through Groups 2 and 3 in both the smears. Nuclear diameter and nuclear area and nuclear cytoplasmic ratio progressively decreased from Group 1 through Groups 2 and 3. Both the methods showed no significant differences among the cellular parameters except in normal controls. CONCLUSION Cytomorphometric analysis of keratinocytes obtained with oral rinse method and wooden spatula can serve as a useful screening aid to detect oral leukoplakia. Oral rinse method being more convenient results in smears of better quality.

Abstract
Haemangiomas are one of the most common benign tumours. Clinicians come across haemangiomas of different subtypes at different locations in the body. They are often faced with the question of whether to treat them or leave it to the natural history of the disease. We present a case of the intramuscular variety of haemangioma found in the unusual location of the tongue in a 60-year-old woman. Fine needle aspiration was inconclusive and on magnetic resonance imaging, it mimicked a malignancy, which prompted treatment. We also review the unique pathology of this variety of haemangioma, which defines their treatment. The radiological attributes of the disease and recurrence rates of surgery are also discussed.

Abstract
BACKGROUND The median survival of technically unresectable oral-cavity cancers (T4a and T4b) with non surgical therapy is 2-12 months. We hypothesized that neoadjuvant chemotherapy (NACT) could reduce the tumour size and result in successful resection and ultimately improved outcomes. We present a retrospective analysis of consecutive patients who received NACT at our centre between January 2008 and August 2012. PATIENTS AND METHODS All patients with technically unresectable oral cancers were assessed in a multidisciplinary clinic and received 2 cycles of NACT. After 2 cycles, patients were reassessed and planned for either surgery with subsequent CTRT or nonsurgical therapy including CT-RT, RT or palliation. SPSS version 16 was used for analysis of locoregional control and overall survival (OS). Univariate and multivariate analysis was done for factors affecting the OS. RESULTS 721 patients with stage IV oral-cavity cancer received NACT. 310 patients (43%) had sufficient reduction in tumour size and underwent surgical resection. Of the remaining patients, 167 received chemoradiation, 3 radical radiation and 241 palliative treatment alone The locoregional control rate at 24 months was 20.6% for the overall cohort, 32% in patients undergoing surgery and 15% in patients undergoing non surgical treatment (p=0.0001). The median estimated OS in patients undergoing surgery was 19.6 months (95% CI, 9.59-25.21 months) and 8.16 months (95%, CI 7.57-8.76) in patients treated with non surgical treatment (p=0.0001). CONCLUSION In our analysis, NACT led to successful resection and improved overall survival in a significant proportion of technically unresectable oral-cancer patients.

Abstract
Background Transverse myelitis (TM) is a relatively infrequent but severe complication in systemic lupus erythematosus (SLE). Owing to its rarity and unfavorable outcome, we investigated its general features on MRI and incidence in the context of lupus activity, to facilitate early recognition and treatment. Methods We report a case of a young man with clinically inactive lupus nephritis but who presented with a sudden attack of myelitis. We performed systematic literature search in Medline to study the clinical features of SLE-related TM. Results From 1960 to April 2013, a total of 72 articles containing 194 cases of lupus myelitis were found. Among acquired articles, 93 patients fulfilled the inclusion criteria. The majority of the cases (88.8%) were female. Longitudinal myelitis was the predominant imaging finding on MRI (71.4%, 45/63). Nearly two-thirds (61/94) of lupus myelitis occurred in association with active lupus, and one-third (33/94) occurred in low disease activity. Conclusions Upon literature review, we found myelitis in SLE more frequently manifested as longitudinal on MRI. Although lupus myelitis often presented at an active phase of SLE, one-third of events happened in the presence of low disease activity. Early initiation of effective immunosuppressive therapy facilitated recovery.

Abstract
OBJECTIVE To study the safety and efficacy of weekly chemotherapy as part of induction chemotherapy, in locally advanced head and neck cancer for patients, who are unfit for upfront radical treatment. MATERIALS AND METHODS It is a retrospective analysis of on-use weekly chemotherapy as Induction chemotherapy in locally advanced head and neck cancer, who are technically unresectable are unfit for upfront radical treatment. Induction chemotherapy given was a 2 drug combination of paclitaxel (80 mg/m 2 ) and carboplatin AUC 2. The decision to give weekly induction chemotherapy was given on the basis of presence of 2 more following features: Poor performance status (ECOG PS 2-3), presence of uncontrolled co morbidities, BMI below 18.5 kg/m 2 and age more than 60 years. The Statistical Package for the Social Sciences software (SPSS version 16.0) was used for analysis. The response rates, toxicity (accordance with CTCAE vs. 4.02), completion rate (Cp) of radical intent treatment post neoadjuvant chemotherapy (NACT), progression-free survival (PFS) and overall survival (OS) are reported. RESULTS Fifteen patients were considered for such therapy. Fourteen out of fifteen patients completed NACT. The median numbers of planned weekly cycles were 6 (3-8). Response (CR + PR) was seen in 10 patients. Overall grade 3-4 toxicity was seen in 6 patients. No toxicity related mortality was noted. The calculated completion rate (Cp) of radical intent treatment post NACT was 46.7%. The median PFS and OS were 10.36 months (95% CI 6.73-14.00 months) and 16.53 months (95% CI 4.22-28.84). CONCLUSION Use of induction chemotherapy with weekly regimen is safe and effective selected cohort of patients with locally advanced disease who are unfit for upfront radical treatment.

Abstract
BACKGROUND Locally advanced and unresectable oral cavity cancers have a poor prognosis. Induction might be beneficial in this setting by reducing tumor bulk and allowing definitive surgery. AIM To analyze the impact of induction chemotherapy on locally advanced, technically unresectable oral cavity cancers. MATERIALS AND METHODS Retrospective analysis of patients with locally advanced oral cavity cancers, who were treated with neoadjuvant chemotherapy (NACT) during the period between June 2009 and December 2010. Data from a prospectively filled database were analyzed for information on patient characteristics, chemotherapy received, toxicity, response rates, local treatment offered, patterns of failure, and overall survival. The statistical analysis was performed with SPSS version 16. RESULTS 123 patients, with a median age of 42 years were analyzed. Buccal mucosa was the most common subsite (68.30%). Three drug regimen was utilized in 26 patients (21.10%) and the rest received two drug regimen. Resectability was achieved in 17 patients treated with 3 drug regimen (68.00%) and 36 patients receiving 2 drug regimen. Febrile neutropenia was seen in 3 patients (3.09%) receiving 2 drug regimen and in 9 patients (34.62%) receiving 3 drug regimen. The estimated median OS was not reached in patients who had clinical response and underwent surgery as opposed to 8 months in patients treated with non-surgical modality post NACT (P = 0.0001). CONCLUSION Induction chemotherapy was effective in converting technically unresectable oral cavity cancers to operable disease in approximately 40% of patients and was associated with significantly improved overall survival in comparison to nonsurgical treatment.

Abstract
Our aim was to evaluate surgical training in gynaecological oncology by assessing the time required by a trainee to complete a single laparoscopic gynaecologic-oncological operation. A total of 135 patients with a BMI < 40 kg/m2, diagnosed with endometrial cancer, underwent a total laparoscopic hysterectomy and bilateral salpingo-oophorectomy (TLH and BSO). Patients in Group I (n = 78) were operated on by a consultant gynaecological oncology surgeon and in Group II (n = 57) by sub-specialist trainees (SSTs). The mean patient age and BMI was 63.5 years and 29.6 kg/m2, respectively, in Group I and 64.5 years and 29.9 kg/m2, respectively, in Group II. Median operating times for Groups I and II were 58 and 90 min, respectively (p < 0.05). Furthermore, significant improvement was noted when comparing the average operating time between the first and second half of SST training. Even experienced gynaecological trainees take significantly longer to perform a reproducible laparoscopic operation. At the completion of training, an SST demonstrates improvement with respect to operation duration but is still not as fast as the trainer.

Abstract
AIM Being a tertiary referral center, we encounter the highest number of oral cancer patients in India, and there is direct involvement of the jaw bone in approximately 40% of these cases. There are no large case series from the Indian subcontinent on metastatic tumors to the jaw bones. With this retrospective analysis, we intend to estimate the incidence of this rare manifestation in the jaw bones in our patients and compare it with the available literature. MATERIALS AND METHODS All patients with biopsy proven metastatic disease involving jaw bones having complete clinical data were included. RESULTS Nineteen out of 10,411 oral cancer patients who reported between the years 2000 and 2005 were included. Breast and thyroid malignancies (5/19 each) were commonest in the females to metastasize to the mandible, whereas in the males, there was no predominant site that resulted in jaw bone metastasis, although mandible was commonly affected. Neuroblastoma of adrenal gland metastasized to maxilla in the age group ranging from 4 months to 16 years. maxilla was the commonest jaw bone affected in this age group. in five cases, jaw bone was found to be the first site of metastasis. CONCLUSIONS There is variation in the primary site that causes metastasis to the jaw bones depending on age, sex and geographic distribution. Jaw bone metastases are rare and can be the first site of metastasis. We get approximately four cases in a year with metastatic disease manifesting in the jaw bones. Metastasis to jaw bone is associated with poor prognosis.

Abstract
Introduction Measuring the patient satisfaction is a very important issue that will help very much in improving the service provided to patients and improve the level of satisfaction. Aim To evaluate patient satisfaction with the cataract surgery service and identify any areas for improvement, determination of patient satisfaction with referral, out-patient consultation, pre-assessment clinic, surgery and post-operative care, also to report patients' comments relating to improvement in service provision. Methodology A retrospective study was undertaken for 150 patients underwent cataract surgery at Barrow General Hospital, UK, the survey sample was by postal questionnaires. We collected our data from the theatre lists for a period of 4 month. Results This study included 150 patients; the response rate was (72%) 108 patients, Most patients were referred from their general practitioner 86.1%, 93 (86.1%) patients were happy with the time interval from seeing their GP to eye clinic. In the eye out patient department many factors significantly affected the level of patient satisfaction, in general the more information provided for the patient the more the satisfaction. Conclusion Patient satisfaction is on important health outcome old understanding both the domains of satisfaction as well as their relative importance to patients is necessary to improve the overall quality of patient care. Meeting the doctor, presenting all relevant information and giving printed information are very important factors in improving the patient's satisfaction with cataract surgery.

Abstract
Squamous cell carcinoma (SCC) of the buccal mucosa in North America is thought to be different from that in the Indian subcontinent. This study compared the treatment outcomes and prognostic factors in 64 patients with SCC of the buccal mucosa treated at Cancer Care Manitoba (CCMB), Canada, and 64 similar patients treated at the Tata Memorial Hospital (TMH), India. Overall, cause-specific and disease-free survival for the two geographical groups were calculated and the impact of individual prognostic factors on survival was assessed. CCMB patients were significantly older (p<0.001), had less differentiated tumour (p=0.053) and had higher chances of positive or close surgical margins (p=0.012). At 5 years, they had lower 5-year overall survival (57.4% versus 80.1%; p<0.001), cancer-specific survival (76.4% versus 85.0%; p=0.043) and disease-free survival (42.9% versus 66.4%; p=0.004). Age had an independent influence on overall survival and cause-specific survival. After adjusting for age there was no difference in cause-specific survival between the two groups (HR=1.20; 95% CI=0.46,3.17; p=0.710). The apparent survival difference between the CCMB and TMH patients was due to the difference in the age of presentation and not because of different biological behaviour.

Abstract
Fine particle number concentration (D(p)>10 nm, cm(-3)), mass concentrations (approximation of PM(2.5), microg m(-3)) and indoor/outdoor number concentration ratio (I/O) measurements have been conducted for the first time in 11 urban households in India, 2002. The results indicate remarkable high indoor number and mass concentrations and I/O number concentration ratios caused by cooking. Besides cooking stoves that used liquefied petroleum gas (LPG) or kerosene as the main fuel, high indoor concentrations can be explained by poor ventilation systems. Particle number concentrations of more than 300,000 cm(-3) and mass concentrations of more than 1000 microg m(-3) were detected in some cases. When the number and mass concentrations during cooking times were statistically compared, a correlation coefficient r>0.50 was observed in 63% of the households. Some households used other fuels like wood and dung cakes along with the main fuel, but also other living activities influenced the concentrations. In some areas, outdoor combustion processes had a negative impact on indoor air quality. The maximum concentrations observed in most cases were due to indoor combustion sources. Reduction of exposure risk and health effects caused by poor indoor air in urban Indian households is possible by improving indoor ventilation and reducing penetration of outdoor particles.

Abstract
BACKGROUND Renal itch is a relatively common and distressing problem for patients with chronic renal failure. Ondansetron, a serotonin type 3 receptor antagonist was developed for relief of chemotherapy induced nausea. Recently, anecdotal reports describe relief of renal itch with ondansetron. OBJECTIVES We performed a double-blind randomized placebo-controlled trial to objectively assess the effectiveness of ondansetron in renal itch. PATIENTS AND METHODS With approval from the local ethical committee, 24 patients on haemodialysis were enrolled in the trial. On a random basis 14 patients were blindly allocated to the ondansetron-placebo sequence and 10 to the placebo-ondansetron sequence. Baseline values for itch were obtained for 7 days before the treatment period and there was a 7-day washout between the treatment periods. During the treatment patients received either 8 mg of ondansetron three times a day or a placebo tablet three times a day for 2 weeks. Patients were asked to record the severity of their pruritus on a visual analogue scale (VAS) twice a day. At the end of the study patients were asked blindly which treatment they had preferred. RESULTS Seventeen patients completed the trial. Pruritus decreased by 16% (95% CI: 0.5-32%) during active treatment and by 25% (95% CI: 9-41%) during treatment with placebo. The change in VAS scores during treatment with ondansetron (P = 0.04) and placebo (P = 0.01) were both significant. Eleven patients expressed a preference, seven for placebo and four for ondansetron. CONCLUSIONS Our results show that ondansetron is no better than placebo in controlling renal itch.

Abstract
Modulation of biotransformation by genetic traits may be important in determining environmentally-induced nephrotoxicity. We conducted a case-control study to investigate the role of occupational hydrocarbon exposure, along with polymorphisms of the genes coding for N-acetyltransferase 2 (NAT2) and glutathione S-transferase mu (GSTmu), in the development of idiopathic membranous glomerulonephritis (IMGN). Patients (n=36) with biopsy-proven IMGN were matched with healthy controls for age, gender, and geographical area. Lifetime hydrocarbon exposure was assessed by a validated questionnaire. The polymorphisms of the NAT2 and GSTmu genes (GSTM1) were defined by use of a polymerase chain reaction on white-cell DNA from peripheral blood. Exposure to hydrocarbons was significantly greater in patients with IMGN than in controls (mean+/-SEM hydrocarbon exposure score 11 003+/-2955.7 vs. 4352+/-1418, p<0.02). NAT2 acetylator status was identical in patients and controls with 23 (63.9%) fast and 13 (36.1%) slow acetylators in each group. GSTmu was present in 15 (41.7%) patients and 16 (44.4%) controls. While occupational exposure to hydrocarbons remains a likely factor in its pathogenesis, further work is required to identify the genetic polymorphisms that modulate the risk of IMGN.

Abstract
Previously, we developed and applied a regional atmospheric mercury model to a domain covering most of North America at a horizontal grid resolution of 100 km. The implication of using this coarse resolution is that point sources of mercury emissions are instantaneously spread over a grid volume of horizontal dimensions 100 x 100 km2 and a vertical dimension equal to the depth of the grid cell where the point source emissions are released. Since point sources comprise a significant majority of a regional mercury emissions inventory, it is important to understand what effect this artificial dilution may have on calculated mercury concentrations and deposition fluxes. To understand this effect, we conducted model simulations using a finer grid, embedded within the original coarse grid, over a sub-domain that includes over 50% of the largest mercury point sources in the north-eastern United States. The horizontal resolution of the fine grid is 20 km, i.e. it is five times smaller than that of the coarse grid. We compared short-term (daily) and long-term (annual) averaged mercury concentrations, and deposition (wet and dry) fluxes on the coarse and fine grids. As expected, the effect of grid resolution is more clearly seen in close proximity to point sources than at remote locations. For short-term averages near major point sources, the peak concentrations and dry deposition fluxes of mercury from the fine grid are almost a factor of two greater than the corresponding estimates from the coarse grid. At remote locations, however, the concentrations and dry deposition peaks estimated by the two model grid resolutions are more comparable. For total wet deposition of mercury, the distinction between the fine and the coarse grid model results is less significant, regardless of the location. This could be due to the redistribution of precipitation fields or the effect of mercury aqueous chemistry. The effect of grid resolution is more important when model estimates are averaged over short time periods, e.g. daily, as opposed to over long periods, e.g. seasonally and annually.

Abstract
We present a comprehensive analysis of the sensitivity of mercury (Hg) human exposure to environmental variables using a multimedia model of the fate and transport of Hg in the environment. The results of the analysis show that the Hg dose is most sensitive to the lake pH, the burial rate of Hg adsorbed to sediments, and the chemical speciation of Hg emissions to the atmosphere. The lake pH has a strong non-linear effect on the methylation rate and bioaccumulation of Hg in fish. The burial of sediments is a major pathway for removing Hg from the lake cycling. The speciation of Hg emissions is important because Hg(II) is deposited much more rapidly than Hg(0). These results highlight the importance of key variables that should be investigated through well-designed field programs, so that we can minimize the overall uncertainties associated with the modeling of mercury fate and transport.

Abstract
Data from the 1990 San Joaquin Valley Air Quality Study/Atmospheric Utility Signatures, Predictions, and Experiments (SJVAQS/AUSPEX) field program in California's San Joaquin Valley (SJV) suggest that both urban and rural areas would have difficulty meeting an 8-hr average O3 standard of 80 ppb. A conceptual model of O3 formation and accumulation in the SJV is formulated based on the chemical, meteorological, and tracer data from SJVAQS/AUSPEX. Two major phenomena appear to lead to high O3 concentrations in the SJV: (1) transport of O3 and precursors from upwind areas (primarily the San Francisco Bay Area, but also the Sacramento Valley) into the SJV, affecting the northern part of the valley, and (2) emissions of precursors, mixing, transport (including long-range transport), and atmospheric reactions within the SJV responsible for regional and urban-scale (e.g., down-wind of Fresno and Bakersfield) distributions of O3. Using this conceptual model, we then conduct a critical evaluation of the meteorological model and air quality model. Areas of model improvements and data needed to understand and properly simulate O3 formation in the SJV are highlighted.

Abstract
The Grand Canyon Visibility Transport Commission (GCVTC) was established by the U.S. Congress to assess the potential impacts of projected growth on atmospheric visibility at Grand Canyon National Park and to make recommendations to the U.S. Environmental Protection Agency on what measures could be taken to avoid such adverse impacts. A critical input to the assessment tool used by the commission was three-dimensional model-derived wind fields used to transport the emissions. This paper describes the evaluation of the wind fields used at various stages in the assessment. Wind fields evaluated included those obtained from the Colorado State University Regional Atmospheric Modeling System (RAMS), the National Meteorological Center's Nested Grid Model (NGM), and the National Oceanic and Atmospheric Administration's Atmospheric Transport and Dispersion (ATAD) trajectory model. The model-derived wind fields were evaluated at multiple vertical levels at several locations in the southwestern United States by determining differences between model predicted winds and winds that were measured using radiosonde and radar wind profiler data. Model-derived winds were also evaluated by determining the percent of time that they were within acceptable differences from measured winds. All models had difficulties, generally meeting the acceptable criteria for less than 50% of the predictions. The RAMS model had a persistent bias toward southwesterly winds at the expense of other directions, especially failing to represent channeling by north-south mountain ranges in the lower levels. The NGM model exhibited a substantial bias in the summer months by extending northwesterly winds in the eastern Pacific Ocean well inland, in contrast to the observed southwesterlies at inland locations. The simpler ATAD trajectory model performed somewhat better than the other models, probably because of its use of more upper air sites. The results of the evaluation indicated that these wind fields could not be used to reliably predict source-receptor impacts on a particular day; thus, seasonally averaged impacts were used in the GCVTC assessment.
