Abstract
Oral mucoceles are mucin filled cavities and lined by ductal epithelium or covered by granulation tissue in retention or extravasation type respectively. The extra-vasation type is very common in the minor salivary glands (particularly in the labial glands), but very infrequent in the major salivary glands, whilst most of the retention cyst affect the major salivary glands. Partial obstruction of duct and spillage of mucin following trauma are the chief etiological factors. Though the two lesions are clinically indistinguishable, the patients are typically older than in the case of extra-vasation type. The case history along with heedful clinical examination of the lesion is crucial for diagnosing mucoceles correctly, but to avoid recurrences histopathological examination is mandatory. The surgical approach to mucoceles is the most common mode of treatment amongst various other techniques including cryosurgery, laser and so on.

Abstract
Abstract
Background
TNBC, defined by the absence of ER, PR, and HER2, is associated with higher risk of recurrence and BC-related mortality, earlier age at diagnosis, menarche, and 1st pregnancy, increased parity, higher BMI, and African-American/Hispanic race. TNBC is a heterogeneous group. Using gene expression analysis, our group described a subset of AR+ ER/PR- BC that exhibits androgen-dependent growth. In vitro studies confirmed the functional role of AR and showed that growth could be abrogated by antiandrogens.(Doane et al 2006) We translated this work into a phase II trial of bicalutamide in pts with AR+ ER/PR- metastatic BC (MBC). (NCT00468715) We now describe the prevalence and clinicopathological characteristics of AR+TNBC in primary disease in a single-institution retrospective cohort.
Methods: We identified 1,032 pts with resectable, TNBC (ER/PR<1%; HER2<2+/FISH<2.2) who had surgery at MSKCC from 1998–2006. Exclusion criteria: neoadjuvant chemotherapy, prior radiation, inflammatory/MBC. IRB approval was obtained. We constructed tissue microarrays (TMA) from 210 primary tumors (> 1 cm) with each tumor represented by three 0.6mm cores. AR was tested with DAKO antibody (Clone AR441; dilution 1:500). TMAs were digitized with a Mirax scanner. MetaMorph image analysis software was used to quantify the ratio of DAB staining to hematoxylin signal. A ratio >1 SD above mean was defined as AR+. AR+ cores were manually reviewed; false positives due to core artifact were excluded. To evaluate clinicopathological variables and differences in recurrence-free survival (RFS) and overall survival (OS) by AR status we used chi-square/t-tests and Kaplan-Meier methods/log-rank test, respectively.
Results: 169 pts had adequate cores for image analysis/quantification of AR. 10% of pts tested AR+ (17/169). Median (med) followup: AR+=6 years (yr), AR-=5.6yr. Demographic/clinicopathological variables: Table 1 (ages in med yr). Overall med age=54yr (29-84). Adjuvant chemotherapy received: AR+ 82%, AR- 87%, p =0.40; 77% received anthracycline/taxane-based therapy. Med time to distant metastasis (DM)=2.1yr (0.2−6.2yr). We were unable to demonstrate a difference in 5yr RFS (69% vs. 77%; p=0.37) or OS (68% vs. 84%; p=0.25) between AR+ and AR- TNBC.
Conclusions: Consistent with our prospective study, AR is expressed in ∼10% of TNBC tumors in this retrospective cohort. The pts in our dataset may be older, postmenopausal, more likely to self-report white race and have T1-2/N0-1 BC. No statistically significant differences were observed in demographic/clinicopathological variables or survival outcomes between AR+ and AR- TNBC. Additional TMA data from our database will be presented.

Abstract
Abstract
Background: Sexual dysfunction is reported after chemotherapy and endocrine therapies. However, the prevalence and severity of sexual dysfunction in premenopausal women undergoing therapy for both local and metastatic disease is not well defined. This study was performed in order to understand the impact of contemporary breast cancer treatment on the prevalence and severity of sexual health in premenopausal women.
Methods: We developed a survey that includes a previously validated questionnaire, the Female Sexual Function Index (FSFI), as well as an established measure of health-related quality of life (the EuroQol EQ-5D), and disease-specific items to characterize sexual dysfunction and its causes based on literature review and expert consultations. Anonymous administration of the surveys was conducted in outpatient clinic waiting areas of the Breast Cancer Center at Memorial Sloan-Kettering Cancer Center (MSKCC), under an IRB waiver of consent.
Results: 372 consecutively approached premenopausal women with breast cancer of any stage, undergoing treatment were each queried once. The mean age was 47. 87% reported current or past hormonal treatment, and 86% reported current or past chemotherapy (76% adjuvant; 24% for metastatic disease). Sexual dysfunction attributed to breast cancer or its treatment, defined as an FSFI score <26, was reported by 75% of respondents with a mean score of 16.3. Among these women, 79% of patients considered their sexual symptoms to be bothersome, with 51% noting moderate or severe levels of bother (score >=5/10). In a multivariate analysis, metastatic disease, development of amenorrhea from cancer treatment, antidepressant use and poorer overall health were each significantly associated with worse FSFI scores. Lower FSFI scores were also significantly associated with worse health-related quality of life.
Conclusion: Sexual dysfunction is prevalent in premenopausal women treated for breast cancer and should be discussed with patients as a potential adverse effect of therapy. Assessment of sexual symptoms throughout treatment and beyond may facilitate the use of potential interventions such as lubricants, dilators, treatment modification and counseling.

Abstract
Abstract
Introduction: Low-income women may be more vulnerable to job loss and prolonged work absence after a diagnosis of breast cancer than their higher-income counterparts. This can have important adverse financial consequences on breast cancer survivors. The identification of early risk factors for long-term unemployment could inform interventions to help patients avoid this outcome. Methods: A consecutive sample of 921 low-income, underinsured or uninsured, English and/or Spanish-speaking women treated for breast cancer through the California Breast and Cervical Cancer Treatment Program was recruited and surveyed 6 months after a diagnosis of breast cancer. Participants completed follow-up telephone surveys at 18, 36, and 60 months post-diagnosis; 539 remained in the cohort at 60 months. This analysis includes only the 315 (58%) women who were employed before diagnosis. Our primary study outcome was prolonged unemployment, defined as being unemployed at every survey. Baseline characteristics (measured in the 6-month survey) were compared between women with prolonged unemployment and those who were working 60 months after diagnosis. Results: The median age of the study sample was 50, and 98% had a baseline annual household income < $40,000. Eighty-five of 315 (27%) women who were employed before diagnosis had prolonged unemployment after diagnosis. In contrast, 168 (53%) were working at 60 months. Baseline predictors of prolonged unemployment after diagnosis include lower household income (p=0.003), inadequacy of financial resources to cover needs (40% vs. 23%, for inadequate vs. adequate, p=0.006), lower education (43%, 30%, and 23% among those who did not complete high school, had a high school diploma, and had a college diploma, respectively, p=0.04), higher comorbidity burden (p=0.006), higher cancer stage at diagnosis (p=0.001), and receipt of chemotherapy (p=0.008). Variables found not to be associated with prolonged unemployment include age, ethnicity, acculturation, marital status, children in the home, social support, job type, type of breast surgery, type of axillary surgery, endocrine therapy, and radiation therapy. In a multivariable analysis that included ethnicity, education, income, chemotherapy, and comorbidity, the latter three variables remained statistically significant predictors of prolonged unemployment, but education and ethnicity were not significantly associated with the outcome. Discussion: More than a quarter of women treated for breast cancer never returned to work during the five years after their diagnosis. In this low-income sample, those with the lowest income appeared to be especially vulnerable to prolonged unemployment, even when controlling for education. It is possible that the income provided by a low-paying job provides a marginal benefit, if any, over disability income, and additional research is needed to better understand this relationship and its financial and psychosocial consequences. Clinical variables also were important predictors of prolonged unemployment. Women with a higher comorbidity burden and those treated with chemotherapy appear to be most vulnerable to prolonged unemployment. This may have clinical implications for informed decision-making between oncologists and their patients.

Abstract
Abstract
Background
BM develops in 65–70% of pts with MBC. RANK and its ligand (RANK-L) can be critical in the development and progression of BM. Src overexpression and deregulation occurs in many solid tumors but it has not been fully characterized although an association between Src activity defined by a gene expression signature and BM particularly in ER+ pts has been described. (Zhang XH et al. Cancer Cell. 2009) Our goal was to elucidate the relationship between Src and RANK expression in BT and BM in relation to estrogen-/progesterone-receptor (ER/PR)/HER2 expression and tumor histology (invasive ductal carcinoma (IDC) vs invasive lobular carcinoma (ILC)).
Methods: Immunohistochemistry (IHC) for RANK (R&D Systems clone 80707) and Src (Cell Applications Inc. Phospho Tyr-416) protein expression was performed on archived paraffin embedded BT and BM. Scoring: 0=negative, 1+=weak, 2+=intermediate, 3+=strong and the percent of positive tumor cells; RANK+ = 2–3+, > 1% of cells; Src+ = 1–3+; > 1% of cells. Associations between RANK/Src expression and tumor characteristics were assessed using the chi-square test or McNemar's test for pairs, as appropriate.
Results: From the MSKCC database, using an IRB-approved waiver of consent, we identified 54 pts with MBC who underwent surgical biopsy of a metastatic bone lesion at our center between 2005–2010, and had tissue available for further testing. 17 corresponding BT samples were identified. At the time of diagnosis, 43 (79.5%) primary tumors were ER or PR (+); 6 (11%) were HER2+; 41 (76%) were invasive ductal carcinoma. 87% of BM expressed RANK and 44% expressed Src. (Table 1) No significant correlation between RANK or Src expression in BM and ER/PR/HER2 status of BT was observed. A significant correlation between RANK expression and BT histology was observed, (p=0.0016): 93% of IDC were RANK (+), in comparison to 50% of invasive lobular carcinomas. RANK expression was not significantly different between primary tumor and metastatic bone samples (p=0.99). There was a borderline significant difference in Src expression between primary and metastatic site (p=.06).
Conclusions: In our cohort, no correlation between RANK or Src by IHC and ER/PR/HER2 was identified but RANK expression was more common in IDC than ILC. Fidelity was high for RANK between primary and metastatic lesions while Src expression may possibly vary.

Abstract
The ideal acetabular component is characterised by reliable, long-term fixation with physiological loading of bone and a low rate of wear. Trabecular metal is a porous construct of tantalum which promotes bony ingrowth, has a modulus of elasticity similar to that of cancellous bone, and should be an excellent material for fixation. Between 2004 and 2006, 55 patients were randomised to receive either a cemented polyethylene or a monobloc trabecular metal acetabular component with a polyethylene articular surface. We measured the peri-prosthetic bone density around the acetabular components for up to two years using dual-energy x-ray absorptiometry. We found evidence that the cemented acetabular component loaded the acetabular bone centromedially whereas the trabecular metal monobloc loaded the lateral rim and behaved like a hemispherical rigid metal component with regard to loading of the acetabular bone. We suspect that this was due to the peripheral titanium rim used for the mechanism of insertion.

Abstract
3 Background: The accurate prediction of outcome from MBC could be useful if it could guide more effective therapies. Because PET/CT combines anatomical with functional imaging it could enable greater individualization of treatment. However, there is substantial SUV variation by anatomic site. In this retrospective, single-institution study, we examine baseline SUV on PET/CT as a predictor of outcome from MBC. Methods: Patients (Pts) with ≥1 metastatic lesion on PET/CT performed ≤60 days of diagnosis of MBC from 01/01/2001-12/31/2008 were identified through institutional databases. Pts who rcvd chemotherapy within 30 days prior to PET/CT were excluded. Electronic medical record reports were reviewed and maximum SUV (SUV-MAX) by site for lesions in bone, liver, lung and lymph node (LN) was recorded. In a secondary analysis, PET/CT scans were reviewed and SUV-MAX recalculated. Relationships between SUV-MAX and OS were assessed using Cox regression by site. Results: We identified 285 pts, median (med) age 57 yrs (range 27-90) who had PET/CT at med of 2.3 yrs (range 0–41) from primary BC (67% ER+ and 21% HER2+). Med time between PET/CT and MBC diagnosis was -9 days (range -58–59). At med follow-up of 53 mths, 163 pts have died. Med OS is 41 mths (95%CI 34-48). The SUV-MAX by site was; bone (N=159) med 7.0 (range 2.1–29.6); liver (N=55) med 8.2 (range 2.9–51.2); lung (N=89) med 4.7 (range 1.1–24.0); LN (N=180) med 6.9 (range 1.2–34.0). On univariate analysis, higher SUV in bone was associated with shorter survival (p<0.001; table). This was maintained in multivariate analyses after adjusting for known prognostic variables (p=0.02). A similar trend for shorter survival for higher SUV was noted in liver (p=0.07). However, no relationship between SUV and OS was noted in lung (p =0.34) and LN (p=0.6). Conclusions: This large retrospective study of pts with chemotherapy-naïve MBC suggests that SUV-MAX in bone strongly correlates with prognosis. [Table: see text]

Abstract
148 Background: Women at increased risk for breast cancer due to a diagnosis of lobular carcinoma in situ (LCIS) have three management options: high risk surveillance +/- chemoprevention (CP) or bilateral prophylactic mastectomy (BPM). Among a large cohort of women with LCIS, we previously reported there were no differences between women choosing CP compared to those choosing surveillance alone. The purpose of this study was to identify patient factors associated with the decision to pursue BPM for LCIS. Methods: We reviewed our prospectively maintained LCIS database to identify women choosing BPM (1995-2009). Comparisons were made between patients who chose BPM versus those who chose high risk surveillance +/- CP. Results: Among 995 pts with LCIS, 795 (80%) chose surveillance alone, 149 (15%) chose CP and 51 (5%) chose BPM. Compared to patients electing surveillance +/- CP patients who pursued BPM were younger at age of LCIS diagnosis (48 vs. 52 yrs, p < 0.001), more likely to have bilateral biopsies with LCIS (14% vs. 3%, p = 0.002) and more likely to be premenopausal (82% vs. 57%, p < 0.001). Patients choosing BPM were also more likely to have additional risk factors for breast cancer including: stronger family histories and extremely dense breasts (Table). Occult breast cancer was found in 4 (8%) BPM patients. At a median follow-up of 54 months (range 0-190 mos), 120/944 (13%) patients in the surveillance +/- CP group developed breast cancer. Conclusions: High-risk surveillance alone is the preferred management option for women with LCIS at our institution. Patients electing BPM are younger and more likely to have other associated risk factors for developing breast cancer. Further research to define how the increased risk imparted by LCIS is augmented by these factors may allow for better risk stratification and more informed discussions with patients.

Abstract
OBJECTIVE Meniscus lesions following trauma or associated with osteoarthritis (OA) have been described, yet meniscus aging has not been systematically analyzed. The objectives of this study were to (1) establish standardized protocols for representative macroscopic and microscopic analysis, (2) improve existing scoring systems, and (3) apply these techniques to a large number of human menisci. DESIGN Medial and lateral menisci from 107 human knees were obtained and cut in two different planes (triangle/cross section and transverse/horizontal section as well) in three separate locations (middle portion, anterior and posterior horns). All sections included vascular and avascular regions and were graded for (1) surface integrity, (2) cellularity, (3) matrix/fiber organization and collagen alignment, and (4) Safranin-O staining intensity. The cartilage in all knee compartments was also scored. RESULTS The new macroscopic and microscopic grading systems showed high inter-reader and intra-reader intraclass correlation coefficients. The major age-related changes in menisci in joints with no or minimal OA included increased Safranin-O staining intensity, decreased cell density, the appearance of acellular zones, and evidence of mucoid degeneration with some loss of collagen fiber organization. The earliest meniscus changes occurred predominantly along the inner rim. Menisci from OA joints showed severe fibrocartilaginous separation of the matrix, extensive fraying, tears and calcification. Abnormal cell arrangements included decreased cellularity, diffuse hypercellularity along with cellular hypertrophy and abnormal cell clusters. In general, the anterior horns of both medial and lateral menisci were less affected by age and OA. CONCLUSIONS New standardized protocols and new validated grading systems allowed us to conduct a more systematic evaluation of changes in aging and OA menisci at a macroscopic and microscopic level. Several meniscus abnormalities appear to be specific to aging in the absence of significant OA. With aging the meniscal surface can be intact but abnormal matrix organization and cellularity were observed within the meniscal substance. The increased Safranin-O staining appears to represent a shift from fibroblastic to chondrocytic phenotype during aging and early degeneration.

Abstract
Traditionally, ozone processing within the food industry has focused on solid foods by either gaseous treatment or washing with ozonized water. However, with the FDA's approval of ozone as a direct additive to food, the potential for liquid applications has emerged. This study investigates the effect of ozone processing on microbial inactivation (E. coli ATCC 25922 and NCTC 12900) and quality parameters (color, phenolic content) of cloudy apple juice. Apple juice samples were ozonated at room temperature (20 ± 1.5 °C) with a generated ozone concentration of 0.048 mg O(3) at a constant flow rate of 0.12 L/min and treatment time of 0 to 10 min. E. coli inactivation kinetics in apple juice were described quantitatively by using the Shoulder log-linear and the Weibull model. Ozone treatment of E. coli in apple juice demonstrate that a desired 5 log reduction can be achieved within 5 min. Apple juice color (L*, a*, and b*) and total phenols were significantly affected by ozone concentration and treatment time.

Abstract
OBJECTIVES Wound healing is a significant healthcare problem in today's medical practice. Despite extensive treatment modalities that are supposed to hasten the wound healing process, the outcomes of existing methods are far from optimal. One such agent that has been tried previously and found controversial in wound healing is phenytoin. In this study, the wound-healing efficacy of phenytoin was investigated in albino rats. MATERIALS AND METHODS 20 male Wistar albino rats were subjected to excisional wounds measuring 500 mm(2) on the back and then randomized to two groups (n = 10): Control group (A) and treatment group (B). The control group received no drug treatment till the end of the study. 1% Phenytoin cream was applied to the wounds of rats in the group B and continued till the 16(th) day of the study. The areas of wounds were measured on the Days 4, 8, 12, and 16 of the experiment. The percentages of the healing wounds were calculated by Walker formula after measurement of the wound area. The total number of days required for complete epithelization of wounds was noted in each group. RESULTS Statistically significant reduction (P < 0.05) in average wound area was seen in Group B (P value=0.0017, 0.0001, 0.0001, 0.0001), respectively, on Days 4, 8, 12, and 16 of the experiment in comparison to Group A. The average number of days required for complete epithelization of wound area was less in Group B as compared to Group A (P=0.0120). The difference was statically significant CONCLUSION In the present study, topical phenytoin accelerated healing of excisional wound in albino rats.

Abstract
Periodontitis is a multifactorial disease with microbial dental plaque as the initiator of periodontal disease. However, the manifestation and progression of the disease is influenced by a wide variety of determinants and factors. The strongest type of causal relationship is the association of systemic and periodontal disease. Hashimotos thyroiditis has also been considered as one of the causes of periodontal disease. As a matter of fact, on an autoimmune basis, in Hashimotos disease and periodontal disease, we have made an attempt to derive the common mechanisms, with an evidence base. The need for this kind of review was due to the fact that the outcome of periodontal therapy did not give the expected results in patients with Hashimoto's thyroiditis. Hence, a possible link between Hashimotos thyroiditis and periodontitis was considered.
