Abstract
We evaluated outcome of 235 primary treatment failure (PTF) diffuse large B-cell lymphoma (DLBCL) patients based on salvage chemotherapy regimen and putative cell-of-origin (COO). Patients were divided into two groups; group A (n = 38) received high-dose cytarabine containing regimen, either DHAP or ESHAP. Patients in group B (n = 197) received ifosfamide, carboplatin, and etoposide (ICE) +/- rituximab. No difference in overall response rates (CR + PR) was observed based on salvage chemotherapy regimen and COO. After adjustment for the presence of ultra high-risk features, overall survival of germinal center B-cell like (GCB) DLBCL patients in group A was not significantly different from survival in group B (HR 0.86, 95% CI 0.46-1.60, p = .64). Similarly, within non-GCB DLBCL cohort, survival in group A was comparable to group B (HR 0.53, 95% CI 0.20-1.44, p = .21). We did not find an outcome difference between two commonly used salvage chemotherapy regimens in patients with PTF DLBCL based on COO.

Abstract
BACKGROUND The impact of MYC proto-oncogene, basic helix-loop-helix (MYC) translocations (with or without additional rearrangements involving the B-cell lymphoma 2 [BCL2] or BCL6 genes) on the response to salvage therapy and survival in patients with diffuse large B-cell lymphoma (DLBCL) who experience primary treatment failure is not well defined. METHODS This was a multicenter, retrospective study of the impact of MYC, BCL2, and BCL6 rearrangements in patients with DLBCL who failed to achieve complete remission or relapsed within 6 months after they completed upfront chemoimmunotherapy. RESULTS The authors examined response to salvage therapy, receipt of hematopoietic cell transplantation (HCT), and survival outcomes in MYC-negative (n = 120), MYC-positive single hit (SH) (n = 20), and MYC-positive double hit/triple hit (DH/TH) (n = 35) cohorts. The overall response rate in these cohorts to first salvage therapy (51%, 50%, and 54%, respectively) and receipt of HCT (52%, 40%, and 43%, respectively) were comparable between the 3 cohorts. The 2-year overall survival rate was 29.9% in the MYC-negative cohort, 0% in the MYC-positive SH cohort, and 9.9% in the MYC-positive DH/TH cohort (P < .001), and no difference was observed between the SH and DH/TH cohorts (P = .8). The higher risk of death for patients with MYC-positive SH DLBCL (hazard ratio, 1.70; 95% confidence interval, 0.98-2.96; P = .06) and those with MYC-positive DH/TH DLBCL (hazard ratio, 2.22; 95% confidence interval, 1.41-3.50; P = .001) persisted after adjusting for covariates. For patients who underwent autologous HCT, the 2-year overall survival rate was 55.4% in the MYC-negative cohort, 0% in the MYC-positive SH cohort, and 19.4% in the MYC-positive DH/TH cohort (P < .001). All 4 MYC-positive patients who underwent allogeneic HCT relapsed in <4 months. CONCLUSIONS Patients with MYC-positive DLBCL who experience primary treatment failure have response rates to similar to those achieved by salvage therapy compared with their MYC-negative counterparts, but their survival is dismal irrespective of additional "hits" and HCT, representing an unmet medical need.

Abstract
Microangipathic hemolytic anemia (MAHA) is a serious diagnosis and difficult to manage in pregnant patients as multiple life threatening conditions could present with MAHA. ADAMTS13 enzyme activity can be affected during pregnancy with multiple factors. A persistent extremely low ADAMTS13 enzyme activity levels, without an inhibitor, after the delivery was an important factor to establish the diagnosis. We present a case of likely congenital ADAMST13 deficiency that manifested for the first time in a pregnant woman at week 37 of pregnancy.

Abstract
We evaluated the association of baseline prognostic factors with conditional net survival among survivors of six subtypes non-Hodgkin lymphoma using the SEER program data from 2000-2012. Among 2-year survivors, further prognosis markedly improved in Burkitt's (BL) and diffuse large B-cell lymphoma (DLBCL), and became the same as for follicular lymphoma (5-year net survival ≥ 85%). Mantle cell lymphoma (MCL) demonstrated the worst prognosis of all studied histologies up to 5 years of survivorship. Age and stage lost prognostic significance in BL within 2 years from diagnosis. Racial disparities in net survival disappeared within 2 years for all subtypes, except in chronic lymphocytic leukemia, where black patients had persistently worse prognosis, and in MCL, where they had unexpectedly better prognosis than other races after 2 years. Many baseline factors may lose their initial prognostic value for lymphoma survivors, which should be considered when counseling patients about their prognosis and long-term surveillance.

Abstract
UNLABELLED Effective Venous Thrombo-Embolism (VTE) prophylaxis is used in less than 50% of oncology patients despite its wide availability. Low molecular weight heparin (LMWH) as a daily injection is an essential tool for effective prophylaxis against deep vein thrombosis (DVT). Daily outpatient self-injection by the patients or their family members is common practice. The effectiveness of this measure depends on patient compliance. OBJECTIVE The purpose of this study is to determine the degree of compliance and the factors that affect compliance to the extended out-patient use of prophylactic LMWH for 1 month after major abdominal/pelvic surgeries in cancer patients at King Hussein Cancer Center (KHCC). PATIENTS AND METHODOLOGY Following major abdominal/pelvic surgeries, data on 160 cancer patients at KHCC from January 2007 until July 2012 were collected concerning knowledge of DVT and compliance with prophylactic self-injections by answering a questionnaire. RESULTS We have achieved a high compliance rate, this was explained by the medical team's role in educating the patients about the risk of VTE and the importance of thromboprophylaxis. The compliance with self-injections was directly associated with younger age, employment and higher degree of education. CONCLUSION The high compliance rate outside clinical trials can be achieved through comprehensive patient education by a well-qualified medical team, clarification of the importance of DVT prophylaxis and patients' support.

Abstract
It is well established that weight loss in general and bariatric surgery in particular can improve glycaemic control in diabetics. Current NICE guidelines recommend that those patients with type 2 diabetes mellitus and a BMI of 35 kg/m(2) or more should be considered for bariatric surgery in order to optimise their glycaemic control and minimise their risk of long-term complications. The commonest bariatric procedure in the UK is the Roux-en-Y gastric bypass that has been shown to result in long-standing type 2 diabetes resolution in 83 % of patients. Since such surgery carries a small but significant risk of mortality, as well as posing considerable lifestyle implications for the patient, numerous studies have been performed with a view to identifying which patients and which procedures are most likely to result in these desired benefits. This paper summarises the existing literature on this topic.

Abstract
Obesity has become an increasingly important health problem over the past 30 years. Presently around a quarter of the UK adult population are obese and this figure is set to increase further in the coming decades. The health consequences of obesity on multiple body systems have been well established as has the financial cost of the condition to both the individuals affected as well as to society as a whole. Bariatric surgery has been shown to be the only long term effective solution in terms of sustained weight loss and comorbidity resolution. The commonest bariatric procedure in the UK is the Roux-en-y gastric bypass which consistently results in the loss of 70%-80% of excess bodyweight. Results however are variable and in order to optimise resource allocation and avoid exposing patients unlikely to benefit from surgery to its inherent risks, much research has been done to try to identify those patients most likely to obtain a good result. The only factor which has been subjected to meta-analysis is that of preoperative weight loss which shows a positive association with postoperative weight loss following bypass surgery. Although the remaining data are not based on level 1 evidence those other preoperatively identifiable factors which are associated with an improved outcome include Caucasian or Hispanic ethnicity, higher educational status, non-shift-work working patterns, female gender and divorced or single marital status. Similarly increased levels of preoperative physical activity and an absence of binge eating behaviour are consistent with a favourable result whereas increased age, smoking and other socioeconomic factors have not been shown to have a significant impact. Conversely diabetes mellitus seems to have a slight negative correlation with postoperative weight loss; however, a history of sexual abuse or psychiatric illness has not been shown to have a lasting influence.

Abstract
INTRODUCTION The aim of this study was to examine the type and frequency of perianal conditions in a contemporary series of febrile neutropenic patients and to examine the risk factors, management options and outcome of septic perianal conditions. METHODS Medical records of all adult febrile neutropenic patients (933 patients) who were admitted during the period from January, 2009 to December 2011 were retrospectively review. All patients with perianal complaints or conditions were included. The clinical features, management and outcome of septic conditions were recorded. RESULTS Of all the reviewed charts, 101 (10.8%) had perianal complaints or conditions. Most of them were non septic (74.3%), like piles and fissures, and were treated conservatively. In 26 patients the diagnosis was a septic condition: abscess (12 patients), fistula (4), inflammation (9) and necrotizing fasciitis (1). Septic conditions were more commonly found in males younger than 40 years. Surgery was done in 13 patients to drain a collection and in 2 patients to debride necrotic tissue. Most patients who had no collection had conservative management. There was 1 fatality only (3.8%) in those 26 patients. CONCLUSION Most of the perianal conditions in febrile neutropenic patients are non septic and are managed conservatively. Septic perianal conditions are not associated with a poor prognosis as in the past. Surgical drainage should be reserved to conditions where there is a collection; otherwise patients should be managed conservatively but with close monitoring.

Abstract
BACKGROUND Pandemic influenza A (hereafter 2009/H1N1) caused significant morbidity and mortality during the 2009 pandemia. Patients with chronic medical conditions and immunosuppressive diseases had a greater risk of complications. However, data regarding the characteristics and outcome of 2009/H1N1 infection in patients with solid tumors are nonexistent. Herein, the authors describe a series of influenza 2009/H1N1 in patients with solid malignancies at 3 major cancer hospitals worldwide. METHODS The authors retrospectively reviewed the records of patients with solid organ malignancies and 2009/H1N1 from The University of Texas M. D. Anderson Cancer Center in Houston, Texas; the Mexican National Cancer Institute, Federal District of Mexico; and King Hussein Cancer Center in Amman, Jordan from the period of the 2009 H1N1 pandemia. Data on demographics, disease characteristics, and outcome were extracted. RESULTS In total, 115 cases were identified during the pandemic influenza among the 3 institutions. High rates of hospitalization (50%), pneumonia (23%), and death (9.5%) were reported. Patients who developed pneumonia and those who died were moderately to severely immunocompromised (P = .001 and P = .006, respectively). A multivariate competing risk analysis demonstrated that a delay >48 hours in starting antiviral therapy was associated significantly with an increased risk of developing pneumonia (P = .013). CONCLUSIONS The 2009/H1N1 pandemic caused severe illness in immunocompromised patients with cancer who had solid tumors, and heavily immunosuppressed patients were at greater risk of developing pneumonia and death. Early initiation of antiviral therapy is crucial in this patient population to decrease morbidity and probably mortality.

Abstract
Carotid endarterectomy (CEA) within two weeks of the index neurological event (INE) achieves maximum stroke prevention. This study assesses the impact of institution-wide policy changes on CEA performance in symptomatic patients. Between two study periods (1 January 2007 and 31 December 2007; 1 August 2008 and 31 July 2009) transient ischaemic attack (TIA) clinics, an acute stroke protocol and utilisation of vascular operating lists, were adopted. Following the changes, the interval between the INE and CEA fell from 23 (n = 65; interquartile range (IQR) 9-66) to 6.5 (n = 52; IQR 2-13.5) days (p < 0.001) with 32.3% v 82.7% performed within two weeks (p < 0.001). Significant improvements were seen in the time taken from onset of symptoms to presentation, and presentation to a carotid duplex and surgical review. Univariate analyses suggest this improvement is associated with the type of INE, point of presentation and the need for further imaging. Implementation of these policies has produced a significant improvement in service provision largely meeting the two-week target.

Abstract
INTRODUCTION The cyclooxygenase-2 (COX-2), responsible for the conversion of arachidonic acid into prostaglandin (PG) E2, is known to increase intracellular cAMP and estrogen production in malignant breast tissue. The aromatase enzyme complex is responsible for local production of estrogens in breast cancer. Increasing evidence supports a role for COX-2 in upregulation of aromatase activity. The aim of this study was to examine the relationship between COX-2 and aromatase mRNA expression in human breast cancer. METHODS A total of 160 breast samples (127 tumor tissues and 33 normal tissues) were analyzed. Levels of transcription were determined using real-time quantitative PCR. COX-2 and aromatase mRNA expression were normalized against CK19. Levels of expression of COX-2 were correlated with those of aromatase using Pearson's correlation method. RESULTS Levels of expression of COX-2/CK19 of both benign and malignant tissues were positively correlated with aromatase/CK19 transcript levels (correlation coefficient = +0.536, P < 0.0001). When we compared levels of expression of both genes in malignant samples only, there was a highly significant positive correlation (r = +0.611, P < 0.00001). CONCLUSION This study demonstrates a strong positive relationship between COX-2 and aromatase mRNA expression, and lends further support to the hypothesis that COX-2 is an upregulator of aromatase in breast tissue.

Abstract
BACKGROUND Steroid sulfatase (STS) is the enzyme responsible for hydrolysing biologically inactive estrogen sulfates to active estrogens. Therefore it plays a significant role in supporting the growth of hormone-dependent tumours of the breast, endometrium and prostate. OATP-B is a member of a family of membrane transporter proteins that regulates the uptake of steroid sulfates through cell membranes. Our objective was to determine, using quantitative PCRA whether the mRNA expression levels from these genes were positively correlated with clinical outcome in human breast cancer. This is the first study in the literature to examine the relationship between STS and OATP-B in human breast cancer and to investigate the potential prognostic value of OATP-B. MATERIALS AND METHODS A total of 153 samples (120 tumour tissues and 33 normal breast tissues) were analysed. The levels of transcription of STS and OATP-B were determined using real-time quantitative PCR and normalized against cytokeratin 19. The levels of expression were analysed against tumour's stage, grade, nodal status, local relapse, distant metastasis, ERalpha, ERbeta and HER1-4 receptor status and survival over a 10 year follow up period. RESULTS The levels of STS mRNA were significantly higher in malignant samples (p=0.031) and in node positive disease (p=0.0222). STS mRNA expression increased with increasing tumour grade but this did not reach statistical significance. A significant increase was also noted in levels correlating with tumour stage when stages TNM1 and TNM2, TNM2 and TNM3, and TNM3 and TNM4 (p=0.00001, 0.0017 and 0.02, respectively) were compared. Furthermore, STS expression levels positively correlated with progression of disease, as levels were significantly higher in samples from patients who developed metastasis, local recurrence, or died of breast cancer when compared to those who were disease free for >10 years (p=0.0036). No significant correlation was found between the levels of STS expression and ERalpha/ERbeta/ status. The levels positively correlated with HER1 and HER3 receptors. The levels of mRNA expression of OATP-B were higher in malignant tissue compared to normal tissue; this, however, did not reach statistical significance (p=0.4045). Levels were also higher in node positive disease (p=0.0672). Expression levels increased with increasing tumour grade and this became statistically significant when comparing grade 1 to 2, and grade 2 to 3 (p=0.0271 and 0.0289, respectively). An increase in levels correlating with TNM tumour staging was also observed; this, however, did not reach statistical significance. There was no significant correlation between OATP-B expression levels and clinical progression of breast cancer. No correlation was found between STS and OATP-B expression levels. CONCLUSION This study demonstrates a compelling trend for STS transcription levels to be higher in cancer tissues and in patients who developed progressive disease. OATP-B expression levels correlated with the grade and stage of the disease, but not with the clinical outcome. These results suggest that STS mRNA has a significant potential as an important predictor of clinical outcome in patients with breast cancer.

Abstract
BACKGROUND Mammary ductoscopy (MD) is a newly developed endoscopic technique that allows direct visualisation of the mammary ductal epithelium using sub-millimetre fiberoptic microendoscopes inserted through the ductal opening onto the nipple surface. These scopes also provide working channels for insufflation, irrigation, ductal lavage, and possible therapeutic intervention. MD can be performed under local anaesthesia in the office setting. The objective of this study is to assess the technical feasibility of mammary ductoscopy, and examine its role in guiding ductal excision surgery and the early diagnosis of malignancy. METHODS Mammary ductoscopy (MD) was performed using a 1 mm fiberoptic microendoscope (Mastascope TM) in 26 patients (age range: 14-73 years): 13 patients undergoing mastectomy (n = 12) or lumpectomy (n = 1) for ductal carcinoma (including 12 cases of DCIS and one case of infiltrating ductal carcinoma) and 13 patients with pathological nipple discharge (PND) and benign breast imaging and simple discharge cytology. Of the latter group: 10 procedures were performed under local anaesthesia (LA) in the office setting and 3 procedures were carried out under general anaesthesia (GA) to guide duct excision surgery. The ductoscopic appearances in this group were graded between 0 and 5 (D0-D5) according to the degree of suspicion. RESULTS Intraoperative MD was accomplished in 11 (84.6%) of 13 patients undergoing surgery for DCIS. MD was unsuccessful in 2 cases: one patient (aged 73 years) had sclerosis of the nipple and one patient had preoperative vital blue injection in the subareolar region as part of the sentinel node biopsy thus resulting in inadequate visualisation. Intraductal pathology was visualised in 8 (80%) of the 10 cases undergoing mastectomy but ductoscopic cytology was positive for malignancy in only 2 cases (sensitivity = 16%, specificity = 100%). In the office setting, MD was accomplished in 9 (90%) out of 10 patients with PND and was well tolerated (mean pain score = 3.8 out of 10: range 0-7). Of these 10 patients; MD was inadequate (D0) in one patient due to complete occlusion of lumen by the lesion, showed a papilloma in 3 patients (D3), duct ectasia (D2) in 3 patients, irregular thickening of the lumen suspicious of DCIS (D4) in one patient and non-specific benign findings (D2) in 2 patients. Three women with benign ductoscopy and ductoscopy-assisted cytology were reassured and treated conservatively. The remaining 7 patients had ductoscopy-guided duct excision which revealed DCIS in one, papilloma in 4 and benign breast disease in 2 patients. Adequate cellular yield was obtained in 7 (70%) out of 10 cases (benign cytology). The three patients who had MD under GA during microdochectomy had benign endoscopic appearances and final histology (one papilloma and 2 cases of duct ectasia). CONCLUSION MD is technically feasible in most patients and has a potential in the early detection of breast cancer. The procedure can be performed safely in the office setting and should be considered in all patients presenting with a single duct PND. MD has the potential to reduce the number of duct excision procedures and minimise the extent of surgical resection. Ductoscopic cytology is not sufficiently sensitive for the diagnosis of malignancy and the development of a biopsy tool that obtains tissue under direct visualisation is required.

Abstract
BACKGROUND It is presently well accepted that the breast exhibits a circadian rhythm reflective of its physiology. There is increasing evidence that rhythms associated with malignant cells proliferation are largely non-circadian. Cancer development appears to generate its own thermal signatures and the complexity of these signatures may be a reflection of its degree of development. The limitations of mammography as a screening modality especially in young women with dense breasts necessitated the development of novel and more effective screening strategies with a high sensitivity and specificity. The aim of this prospective study was to evaluate the feasibility of dynamic thermal analysis (DTA) as a potential breast cancer screening tool. METHODS 173 women undergoing mammography as part of clinical assessment of their breast symptoms were recruited prior to having a biopsy. Thermal data from the breast surface were collected every five minutes for a period of 48 hours using eight thermal sensors placed on each breast surface [First Warning System (FWS), Lifeline Biotechnologies, Florida, USA]. Thermal data were recorded by microprocessors during the test period and analysed using specially developed statistical software. Temperature points from each contra-lateral sensor are plotted against each other to form a thermal motion picture of a lesion's physiological activity. DTA interpretations [positive (abnormal thermal signature) and negative (normal thermal signature)] were compared with mammography and final histology findings. RESULTS 118 (68%) of participating patients, were found to have breast cancer on final histology. Mammography was diagnostic of malignancy (M5) in 55 (47%), indeterminate (M3, M4) in 54 (46%) and normal/benign (M1, M2) in 9 (8%) patients. DTA data was available on 160 (92.5%) participants. Using our initial algorithm, DTA was interpreted as positive in 113 patients and negative in 47 patients. Abnormal thermal signatures were found in 76 (72%) out of 105 breast cancer patients and 37 of the 55 benign cases. Then we developed a new algorithm using multiple-layer perception and SoftMax output artificial neural networks (ANN) on a subgroup (n = 38) of recorded files. The sensitivity improved to 76% (16/21) and false positives decreased to 26% (7/27) CONCLUSION DTA of the breast is a feasible, non invasive approach that seems to be sensitive for the detection of breast cancer. However, the test has a limited specificity that can be improved further using ANN. Prospective multi-centre trials are required to validate this promising modality as an adjunct to screening mammography especially in young women with dense breasts.

Abstract
INTRODUCTION There is substantial evidence that breast cancer tissue contains all the enzymes responsible for the local biosynthesis of estrogens from circulating precursors. The cytochrome P-450 aromatase enzyme complex is responsible for the conversion of C19 androgens to estrogens and 17-beta-hydroxysteroid dehydrogenase (17-I(2)-HSD) type 1 catalyses the inter-conversion of estrone to the biologically more potent estradiol. The gene encoding for the cytochrome P-450 aromatase is known as CYP19 (15q21.2). It is well established that increased exposure to local estrogens is an important risk factor in the genesis and growth of breast cancer. The aim of this study is to investigate the relationship between CYP19 and 17-beta-HSD type 1A mRNA expression and clinico-pathological parameters of human breast cancer. METHODS One hundred and twenty seven tumor tissues and 33 normal tissues were analyzed. The levels of transcription of CYP19 and 17-beta-HSD type 1 were determined using real-time quantitative PCR. The mRNA expression was normalized against CK19. Levels of expression were analyzed against tumorâ's stage, grade, nodal status, local relapse, distant metastasis and survival over a 120A months follow up period. In addition, the levels were analyzed against estrogen receptor (ER) and HER1-4 status. RESULTS Overall, high tumor levels of mRNA expression of CYP19 and 17-beta-HSD type 1 correlated with poor survival (p=0.0105 and p=0.0182, respectively). Increased levels of CYP19 mRNA expression positively correlated with disease progression as levels were significantly higher in samples of patients who had distant metastasis and local recurrence and/or died of breast related causes when compared to those who were disease free for >10 years (p=0.0015). We also observed higher levels of CYP19 mRNA in tumor samples compared to normal breast tissue. However, this reached statistical significance only when comparing grade 1 tumors with normal tissue (p=0.01). There was no correlation between CYP19á mRNA expression and tumor stage, lymph node status and tumor grade. There was however a trend for a positive correlation between CYP19 and ER mRNA expressions (p=0.06). No significant difference in 17-beta-HSD type 1 expression between normal and cancerous tissues was observed. In tumor samples, we observed an increase in levels correlating with tumor's grade. This correlation was statistically significant when we compared grade 1 with grade 2 and grade 1 with grade 3 (p=0.0031 and 0.0251, respectively). CONCLUSION Our study shows that higher levels of the enzymes responsible for the local biosynthesis of estrogens especially aromatase are associated with a poor clinical outcome in patients with breast cancer.

Abstract
Sentinel lymph node biopsy (SLNB) is a simple technique that uses subdermal or peri-tumoral injection of vital blue dye and/or radioactive isotope to identify the first lymph node(s) draining the primary tumor. It has been shown to accurately predict axillary node status in patients with clinically node negative breast cancer. The SLNB is emerging as a new standard of care in patients with early breast cancer. However, the use of methylene blue (MB) dye can be associated with a number of local complications due to its tissue reactive properties. We report a rare case of skin and fat necrosis followed by a dry gangrene of the skin in a female patient with breast cancer who underwent SLNB localization using peri-tumoral injection of MB dye in another institution. This case and literature review suggest that the use of MB dye for SLNB identification should be avoided and replaced with alternative types of blue dye such as Patent Blue V preferably in conjunction with a radioactive isotope tracer.

Abstract
INTRODUCTION Breast cancer is a classic model of a hormone-dependent malignancy. Since the drugs used for ovulation induction as part of in vitro fertilization (IVF) treatment increase the levels of endogenous gonadal hormones, concerns have arisen regarding a possible association between IVF and the risk of developing breast cancer. The aim of this paper was to review the literature and examine the potential effects of IVF treatment on breast cancer risk. METHODS Medline search was conducted using the key words below in English-language articles. Further papers were obtained using the bibliographies of relevant articles. Furthermore, a combined analysis of retrieved data was performed. RESULTS Fifteen studies were identified; of these, 11 were cohort studies and 4 were case-control studies. None of the individual studies showed an overall significant association between IVF and breast cancer and, in fact, one study showed that treatment with hCG significantly reduced the risk of breast cancer in women whose maximum nonpregnant body mass index was less than 27.5. A combined analysis of the cohort studies including a total of 60,050 women treated with ovulation induction/IVF showed no significant association between these treatments and increased risk of breast cancer (observed vs. expected: 601 vs. 568, pooled relative risk [RR] = 1.06, P = 0.337). The case-control studies included a total of 11,303 women in the breast cancer groups and 10,930 controls. Women in the breast cancer groups were slightly less likely to have received IVF (2.2% vs. 2.5%, pooled RR = 0.88, P = 0.231). However, one study showed that infertility treatment was associated with an increased risk of breast cancer of borderline significance among women with a family history of the disease. Another study showed that the incidence of breast cancer within the first year of exposure to fertility drugs was higher than expected, possibly due to the promotion of preexisting cancer lesions caused by superovulation or due to the early diagnosis made in the course of IVF treatment. Conflicting results were reported regarding the type of fertility treatment and breast cancer risk. CONCLUSION Overall, there is no clear evidence that ovulation induction or IVF increases the risk of breast cancer. However, there may be a transient increase in the incidence of breast cancer in the first year due to earlier diagnosis. Furthermore, the risk may be increased in women with a positive family history. Future research should focus on the type of fertility treatment used and breast cancer risk. Aromatase inhibitors should be evaluated further as an alternative to standard ovulation-inducing drugs.

Abstract
BACKGROUND Dietary elements and, in particular, dairy products have been implicated in the etiology of breast cancer. High saturated fat contents, contaminants such as pesticides, and insulin-like growth factor I (IGF-1) have been hypothesized as possible carcinogenic factors. In contrast, calcium, vitamin D, and conjugated linoleic acid (CLA) all are considered to reduce breast cancer risk. We aim to review the current epidemiological literature on the relationship between the intake of dairy products and breast cancer risk. METHODS A Medline search was conducted using the key words breast neoplasms and dairy products. Further articles were obtained by cross-matching references of relevant articles. Thirty-nine case-control and 11 cohort studies were identified since 1981. Two meta-analyses and several review articles were also noted. RESULTS Results from previous studies were analyzed and comparisons were made between each type of study. Controversy exists regarding this subject and we found conflicting evidence in recent literature regarding this hypothesis. CONCLUSION There is no substantial epidemiological evidence to support a significant link between the intake of dairy products and breast cancer risk.

Abstract
Background Telomerase is a ribonucleoprotein enzyme that synthesises telomeres after cell division and maintains chromosomal length and stability thus leading to cellular immortalisation. The hTERT (human telomerase reverse transcriptase) subunit seems to be the rate-limiting determinant of telomerase and knowledge of factors controlling hTERT transcription may be useful in therapeutic strategies. The hTERT promoter contains binding sites for c-Myc and there is some experimental and in vitro evidence that c-Myc may increase hTERT expression. We previously reported no correlation between c-Myc mRNA expression and hTERT mRNA or telomerase activity in human breast cancer. This study aims to examine the correlation between hTERT expression as determined by immunohistochemistry and c-Myc expression, lymph node status, and tumour size and grade in human breast cancer. Materials and methods The immunohistochemical expression of hTERT and c-Myc was investigated in 38 malignant breast tumours. The expression of hTERT was then correlated with the lymph node status, c-Myc expression and other clinicopathological parameters of the tumours. Results hTERT expression was positive in 27 (71%) of the 38 tumours. 15 (79%) of 19 node positive tumours were hTERT positive compared with 11 (63%) of 19 node negative tumours. The expression was higher in node positive tumours but this failed to reach statistical significance (p = 0.388). There was no significant association with tumour size, tumour grade or c-Myc expression. However, hTERT expression correlated positively with patients' age (correlation coefficient = 0.415, p = 0.0097). Conclusion hTERT protein expression is independent of lymph node status, tumour size and grade and c-Myc protein expression in human breast cancer

Abstract
Background The objective of this study was to determine the concordance rate between core needle biopsy (CNB) and surgical excision of invasive breast cancer regarding the oestrogen receptor (ER) and Progesterone receptor (PgR) status as determined by Immunohistochemistry (IHC). Methods Hormone receptor status was established using IHC (using quickscore system 0–8) on preoperative CNB and subsequent surgical excision in 93 patients with invasive breast cancer. Results were compared taking into account tumour's size, grade, and patient's age. Results The ER concordance rate between CNB and surgical excisions was 95%. The PgR concordance rate was 89%. This shows that CNB has a sensitivity of 97% for ER and 95% for PgR. There is a positive correlation of ER and PgR between CNB and surgical excision (p < 0.000001). There was no significant difference in the number of core biopsies between concordant and discordant cases. Conclusion Preoperative core biopsy is highly sensitive for the IHC detection of ER and PgR in invasive breast cancer. The concordance rate is higher for ER than PgR, which could be due to the fact that ER is more homogeneously distributed.

Abstract
We report the first case in the medical literature of a pneumothorax complicating fine needle aspiration cytology (FNAC) of a breast lump in a woman with a mild form of Poland's syndrome. The pneumothorax was treated conservatively. This is the first case of breast FNA-related pneumothorax seen in our clinical practice. We believe that the absence of pectoral muscles has increased the risk of this complication. We have also diagnosed an incidental screen-detected breast cancer affecting the ipsilateral breast in the same patient. We conclude that caution should be exercised when performing FNAC of breast lesions in patients with Poland's syndrome. The procedure should be preferably performed under image guidance in such patients in order to minimise the risk of this complication.

Abstract
It is now recognised that the breast exhibits a circadian rhythm which reflects its physiology. There is increasing evidence that rhythms associated with malignant cells proliferation are largely non-circadian and that a circadian to ultradian shift may be a general correlation to neoplasia.Cancer development appears to generate its own thermal signatures and the complexity of these signatures may be a reflection of its degree of development.The limitations of mammography as a screening modality especially in young women with dense breasts necessitated the development of novel and more effective screening strategies with a high sensitivity and specificity. Dynamic thermal analysis of the breast is a safe, non invasive approach that seems to be sensitive for the early detection of breast cancer.This article focuses on dynamic thermal analysis as an evolving method in breast cancer detection in pre-menopausal women with dense breast tissue. Prospective multi-centre trials are required to validate this promising modality in screening.The issue of false positives require further investigation using molecular genetic markers of malignancy and novel techniques such as mammary ductoscopy.

Abstract
Functional Endoscopic Sinus Surgery (FESS) is a procedure routinely performed for chronic rhinosinusitis. The Glasgow Benefit Inventory (GBI), a post interventional questionnaire with General, Social support and Physical Health subscales, was posted to 121 patients. Seventy seven replies were received (63.6%), 31 of the respondents were female and 46 male. Forty four procedures were performed for nasal polyposis and 33 for sinusitis. Overall 14 patients had unilateral sinus surgery, 63 had bilateral procedures and the mean follow up period was 28 months (range 6 to 55 months). The GBI scores were mainly positive, indicating a benefit from the procedure. On comparing polyposis and sinusitis scores, the difference in the Total GBI and General Subscale scores indicated a greater benefit for polyp disease (p = 0.045 and 0.022). No statistical difference was seen on comparing the scores for female vs. male, by age, bilateral vs. unilateral or by follow up period. This study validates FESS as a procedure for rhinosinusitis as it leads to an improvement in quality of life of patients.
