Abstract
OBJECTIVES Multiple sclerosis is diagnosed based on clinical and laboratory findings, including cerebrospinal fluid (CSF) oligoclonal banding (OCB) analysis. The lack of updated CSF OCB laboratory guidelines in Canada has likely led to variation in processes and reporting across clinical laboratories. As a first step to developing harmonized laboratory recommendations, we examined current CSF OCB processes, reporting, and interpretation across all Canadian clinical laboratories currently performing this test. DESIGN AND METHODS A survey of 39 questions was sent to clinical chemists at all 13 Canadian clinical laboratories performing CSF OCB analysis. The survey included questions regarding quality control processes, reporting practices for CSF gel electrophoresis pattern interpretation, and associated tests and calculated indices. RESULTS The survey response rate was 100%. Most (10/13) laboratories use ≥2 CSF-specific bands (2017 McDonald Criteria) as their CSF OCB positivity cut-off and only 2/13 report the number of bands with every report. Most (8/13 and 9/13) laboratories report an inflammatory response pattern and monoclonal gammopathy pattern, respectively. However, the process for reporting and/or confirming a monoclonal gammopathy varies widely. Variation was observed for reference intervals, units, and the panel of reported associated tests and calculated indices. The maximum acceptable time interval between paired CSF and serum collections varied from 24 hours to no limit. CONCLUSIONS Profound variation exists in processes, reporting, and interpretation of CSF OCB and associated tests and indices across Canadian clinical laboratories. Harmonization of CSF OCB analysis is required to ensure continuity and quality of patient care. Our detailed assessment of current practice variation highlights the need for clinical stakeholder engagement and further data analysis to support optimal interpretation and reporting practices, which will aid in developing harmonized laboratory recommendations.

AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
BACKGROUND Overactive bladder (OAB) syndrome is a symptom complex affecting 12-14% of the UK adult female population. Symptoms include urinary urgency, with or without urgency incontinence, increased daytime urinary frequency and nocturia. OAB has a negative impact on women's social, physical, and psychological wellbeing. Initial treatment includes lifestyle modifications, bladder retraining, pelvic floor exercises and pharmacological therapy. However, these measures are unsuccessful in 25-40% of women (refractory OAB). Before considering invasive treatments, such as Botulinum toxin injection or sacral neuromodulation, most guidelines recommend urodynamics to confirm diagnosis of detrusor overactivity (DO). However, urodynamics may fail to show evidence of DO in up to 45% of cases, hence the need to evaluate its effectiveness and cost-effectiveness. FUTURE (Female Urgency, Trial of Urodynamics as Routine Evaluation) aims to test the hypothesis that, in women with refractory OAB, urodynamics and comprehensive clinical assessment is associated with superior patient-reported outcomes following treatment and is more cost-effective, compared to comprehensive clinical assessment only. METHODS FUTURE is a pragmatic, multi-centre, superiority randomised controlled trial. Women aged ≥ 18 years with refractory OAB or urgency predominant mixed urinary incontinence, and who have failed/not tolerated conservative and medical treatment, are considered for trial entry. We aim to recruit 1096 women from approximately 60 secondary/tertiary care hospitals across the UK. All consenting women will complete questionnaires at baseline, 3 months, 6 months and 15 months post-randomisation. The primary outcome is participant-reported success at 15 months post-randomisation measured using the Patient Global Impression of Improvement. The primary economic outcome is incremental cost per quality-adjusted life year gained at 15 months. The secondary outcomes include adverse events, impact on other urinary symptoms and health-related quality of life. Qualitative interviews with participants and clinicians and a health economic evaluation will also be conducted. The statistical analysis of the primary outcome will be by intention-to-treat. Results will be presented as estimates and 95% CIs. DISCUSSION The FUTURE study will inform patients, clinicians and policy makers whether routine urodynamics improves treatment outcomes in women with refractory OAB and whether it is cost-effective.

Abstract
Foodborne illnesses are a major threat to public health also leading to significant mortality and financial and reputational damage to industry. It is very important to detect pathogen presence in food products early, rapidly, and accurately to avoid potential outbreaks and economic loss. However, "gold standard" culture methods, including enrichment of pathogens, can take up to several days. Moreover, the food matrix often interferes with nucleic acid amplification methods of detection, requiring DNA extraction from the sample for successful molecular detection of pathogens. Here, we introduce a "biphasic" amplification method that can achieve high sensitivity detection with background noise from ground beef food samples without culture or other extraction methods in 2.5 h. Homogenized ground beef is dried resulting in an increase in porosity of the dried food matrix to allowing amplification enzymes and primers to access the target DNA and initiate the reaction within the dried food matrix. Using Loop Mediated Isothermal Amplification, we demonstrate the detection of 1-3 cfu of Escherichia coli bacteria in 30 mg of dried food matrix. Our approach significantly lowers the time to result to less than a few hours and have a pronounced impact on reduction of instrumentation complexity and costs.

Abstract
Biomedical diagnostics based on microfluidic devices have the potential to significantly benefit human health; however, the manufacturing of microfluidic devices is a key limitation to their widespread adoption. Outbreaks of infectious disease continue to demonstrate the need for simple, sensitive, and translatable tests for point-of-care use. Additive manufacturing (AM) is an attractive alternative to conventional approaches for microfluidic device manufacturing based on injection molding; however, there is a need for development and validation of new AM process capabilities and materials that are compatible with microfluidic diagnostics. In this paper, we demonstrate the development and characterization of AM cartridges using continuous liquid interface production (CLIP) and investigate process characteristics and capabilities of the AM microfluidic device manufacturing. We find that CLIP accurately produces microfluidic channels as small as 400 μm and that it is possible to routinely produce fluid channels as small as 100 μm with high repeatability. We also developed a loop-mediated isothermal amplification (LAMP) assay for detection of E. coli from whole blood directly on the CLIP-based AM microfluidic cartridges, with a 50 cfu/μL limit of detection, validating the use of CLIP processes and materials for pathogen detection. The portable diagnostic platform presented in this paper could be used to investigate and validate other AM processes for microfluidic diagnostics and could be an important component of scaling up the diagnostics for current and future infectious diseases and pandemics.

Abstract
The COVID-19 pandemic has underscored the shortcomings in the deployment of state-of-the-art diagnostics platforms. Although several polymerase chain reaction (PCR)-based techniques have been rapidly developed to meet the growing testing needs, such techniques often need samples collected through a swab, the use of RNA extraction kits, and expensive thermocyclers in order to successfully perform the test. Isothermal amplification-based approaches have also been recently demonstrated for rapid severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection by minimizing sample preparation while also reducing the instrumentation and reaction complexity. In addition, there are limited reports of saliva as the sample source, and some of these indicate inferior sensitivity when comparing reverse transcription loop-mediated isothermal amplification (RT-LAMP) with PCR-based techniques. In this paper, we demonstrate an improved sensitivity assay from saliva using a two-step RT-LAMP assay, where a short 10 min RT step is performed with only B3 and backward inner primers before the final reaction. We show that while the one-step RT-LAMP demonstrates satisfactory results, the optimized two-step approach allows detection of only few molecules per reaction and performs significantly better than the one-step RT-LAMP and conventional two-step RT-LAMP approaches with all primers included in the RT step. We show control measurements with RT-PCR, and importantly, we demonstrate RNA extraction-free RT-LAMP-based assays for detection of SARS-CoV-2 from viral transport media and saliva clinical samples.

Abstract
Existing three-dimensional (3D) culture techniques are limited by trade-offs between throughput, capacity for high-resolution imaging in living state, and geometric control. Here, we introduce a modular microscale hanging drop culture where simple design elements allow high replicates for drug screening, direct on-chip real-time or high-resolution confocal microscopy, and geometric control in 3D. Thousands of spheroids can be formed on our microchip in a single step and without any selective pressure from specific matrices. Microchip cultures from human LN229 glioblastoma and patient-derived mouse xenograft cells retained genomic alterations of originating tumors based on mate pair sequencing. We measured response to drugs over time with real-time microscopy on-chip. Last, by engineering droplets to form predetermined geometric shapes, we were able to manipulate the geometry of cultured cell masses. These outcomes can enable broad applications in advancing personalized medicine for cancer and drug discovery, tissue engineering, and stem cell research.

Abstract
The COVID-19 pandemic provides an urgent example where a gap exists between availability of state-of-the-art diagnostics and current needs. As assay protocols and primer sequences become widely known, many laboratories perform diagnostic tests using methods such as RT-PCR or reverse transcription loop mediated isothermal amplification (RT-LAMP). Here, we report an RT-LAMP isothermal assay for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus and demonstrate the assay on clinical samples using a simple and accessible point-of-care (POC) instrument. We characterized the assay by dipping swabs into synthetic nasal fluid spiked with the virus, moving the swab to viral transport medium (VTM), and sampling a volume of the VTM to perform the RT-LAMP assay without an RNA extraction kit. The assay has a limit of detection (LOD) of 50 RNA copies per μL in the VTM solution within 30 min. We further demonstrate our assay by detecting SARS-CoV-2 viruses from 20 clinical samples. Finally, we demonstrate a portable and real-time POC device to detect SARS-CoV-2 from VTM samples using an additively manufactured three-dimensional cartridge and a smartphone-based reader. The POC system was tested using 10 clinical samples, and was able to detect SARS-CoV-2 from these clinical samples by distinguishing positive samples from negative samples after 30 min. The POC tests are in complete agreement with RT-PCR controls. This work demonstrates an alternative pathway for SARS-CoV-2 diagnostics that does not require conventional laboratory infrastructure, in settings where diagnosis is required at the point of sample collection.

Abstract
The COVID-19 pandemic provides an urgent example where a gap exists between availability of state-of-the-art diagnostics and current needs. As assay details and primer sequences become widely known, many laboratories could perform diagnostic tests using methods such as RT-PCR or isothermal RT-LAMP amplification. A key advantage of RT-LAMP based approaches compared to RT-PCR is that RT-LAMP is known to be robust in detecting targets from unprocessed samples. In addition, RT-LAMP assays are performed at a constant temperature enabling speed, simplicity, and point-of-use testing. Here, we provide the details of an RT-LAMP isothermal assay for the detection of SARS-CoV-2 virus with performance comparable to currently approved tests using RT-PCR. We characterize the assay by introducing swabs in virus spiked synthetic nasal fluids, moving the swab to viral transport medium (VTM), and using a volume of that VTM for performing the amplification without an RNA extraction kit. The assay has a Limit-of-Detection (LOD) of 50 RNA copies/μL in the VTM solution within 20 minutes, and LOD of 5000 RNA copies/μL in the nasal solution. Additionally, we show the utility of this assay for real-time point-of-use testing by demonstrating detection of SARS-CoV-2 virus in less than 40 minutes using an additively manufactured cartridge and a smartphone-based reader. Finally, we explore the speed and cost advantages by comparing the required resources and workflows with RT-PCR. This work could accelerate the development and availability of SARS-CoV-2 diagnostics by proving alternatives to conventional laboratory benchtop tests.

Abstract
Background: Gastric cancer is the 5th most common cancer in the world and 2nd leading cause of cancer deaths. It has marked geographic incidence variation. Most common in Japan, China, other East Asian countries, Eastern Europe and South America. There is sharp decrease in incidence in western countries over the past 60 years but incidence of GE junction and proximal gastric tumors is increasing. In state of Kuwait in 2012 ASR was 2.6/100,000 population (similar to other Gulf countries; apart from Oman). There are many known risk factors including eating smoked and salted food and H. pylori infection. Aim: The aim of this study is to analyze gastric cancer diagnosed cases from 2009 to 2015 in Kuwait and to analyze clinicopathological criteria and prognostic factors. Methods: A total of 145 adult patients with newly diagnosed gastric cancers were treated and followed-up at Kuwait Cancer Control Center (KCCC) between 2009-2015. Patients' data were examined retrospectively. In all cases: age, performance status, sex, ethnicity, smoking and dietary habit, tumor site, pathology, staging and type of treatment were identified. Survival analysis was done using Kaplan-Meier, and comparison was done using long-rank test. Results: The median age at diagnosis was 54 (29-94). Men represented 63.5%. 75.2% had adenocarcinoma, 14.5% gastric lymphoma, 6.2% GIST, 3.4% carcinoid and 1 case squamous cell carcinoma. For gastric adenocarcinoma, 22 were metastatic (20.2%). In spite of composing almost 25% of country population and expected high incidence in their home countries, only 19.5% of patients were Asian with known habit of spicy food intake. 31% of patients were smokers. Performance at diagnosis was ECOG 0-1 in majority. Median follow-up was 45 months (1-89) and median overall survival was 34 months (0.5-89). Almost half of tumors were poorly differentiated with signet-ring feature in 36.8%. 12.6% presented with clinically advanced tumor but after surgery the number upstaged to be 25.9% (Stage III). Tumor epicenter localization was almost equivalent with 43 (49.4%) localized proximally and 44 (50.6%) distally. Surgery was the main treatment in majority (85.1%) while radiation was used in 58.6% and chemotherapy in 74.4% (adjuvant, neoadjuvant or concomitant). 22 patients failed; 7 locoregionally, 15 had distant metastasis while 2 patients failed both locally and distantly. Close surgical margins, and proximal localization were poor prognostic factors. Age and ethnicity had no impact on outcomes in our cohort. Conclusion: Gastric adenocarcinoma in Kuwait has similar profile to that documented worldwide and regionally (apart from Oman). Proximal tumors represent a challenge and has poorer prognosis that may need more intensification of treatment. Current (neo)adjuvant treatment seem to be effective in our population. Molecular profiling and studies are needed for further understanding of this potentially curable disease.

Abstract
Abstract
In the current study, an assessment of the melt-compounding approach upon the behavior of blast furnace slag (BFS) filled polypropylene (PP) is reported. Two melt-compounding technologies are compared in terms of thermodynamic considerations as well as final behavior of the produced compounds. For this comparison, three PP-BFS formulations are introduced, where non-treated BFS is melt-mixed with PP via (1) internal lab mixer (IM) and (2) co-rotating twin-screw compounder (TSC). PP-BFS compounds from both processes are formed into plates via compression molding, characterized and tested for rheological, thermal and mechanical behavior. Processing parameters were evaluated for both processes such as specific shear work, residence time and shear rates. In addition, the rheological, thermal and mechanical behavior of comparable compounds are evaluated. The calculated specific shear work values for IM and TSC are 0.15 and 0.1 kW · h · kg−1. Calculated residence time for TSC is 55 s. Regarding the rheological behavior, it was found that melt mixing via both technologies did not show major differences in complex viscosity or storage- and loss moduli values. DSC findings show that crystallization and melting temperatures of IM- and TSC formulations are comparable. Decreased strain values are noticed for TSC compounds, while tensile modulus is found to be independent of process variation.

Abstract
It is almost a decade since the highly pathogenic H5N1 avian influenza virus (A/H5N1) of clade 2.2.1 was introduced to Egypt in 2005, most likely, via wild birds; marking the longest endemic status of influenza viruses in poultry outside Asia. The endemic A/H5N1 in Egypt still compromises the poultry industry, poses serious hazards to public health and threatens to become potentially pandemic. The control strategies adopted for A/H5N1 in Egyptian poultry using diverse vaccines in commercialized poultry neither eliminated the virus nor did they decrease its evolutionary rate. Several virus clades have evolved, a few of them disappeared and others prevailed. Disparate evolutionary traits in both birds and humans were manifested by accumulation of clade-specific mutations across viral genomes driven by a variety of selection pressures. Viruses in vaccinated poultry populations displayed higher mutation rates at the immunogenic epitopes, promoting viral escape and reducing vaccine efficiency. On the other hand, viruses isolated from humans displayed changes in the receptor binding domain, which increased the viral affinity to bind to human-type glycan receptors. Moreover, viral pathogenicity exhibited several patterns in different hosts. This review aims to provide an overview of the viral evolution, pathogenicity and vaccine efficacy of A/H5N1 in Egypt during the last ten years.

Abstract
We proposed an efficient method for classification of diffused liver diseases based on Gabor wavelet. It is well known that Gabor wavelets attain maximum joint space-frequency resolution which is highly significant in the process of texture extraction and presentation. This property has been explored here as the proposed method outperforms the classification rate obtained by using dyadic wavelets and methods based on statistical properties of textures. The feature vector is relatively small compared to other methods. This has a significant impact on the speed of retrieval process. In addition, the proposed algorithm is not sensitive to shift of the image contents. Since shifting the contents of an image will cause a circular shift of the Gabor filter coefficients in each sub-band. The proposed algorithm applied to discriminate ultrasonic liver images into three disease states that are normal liver, liver hepatitis and cirrhosis. In our experiment 45 liver sample images from each three disease states which already proven by needle biopsy were used. We achieved the sensitivity 85% in the distinction between normal and hepatitis liver images and 86% in the distinction between normal and cirrhosis liver images. Based on our experiments, the Gabor wavelet is more appropriate than dyadic wavelets and statistical based methods for texture classification as it leads to higher classification accuracy.

Selective targeting of therapeutic drugs using antibody-drug conjugates (ADC) might be useful in pancreatic cancer therapy. Methods: ADCs composed of SN-38 coupled to an internalizing anti-TROP-2 antibody, an antigen found on many epithelial cancers, or to the non-internalizing anti-mucin humanized IgG, were prepared (6 SN-38/IgG). Nude mice bearing s.c. Capan-1 or BxPC3 xenografts (∼0.35 cm3) were given multiple ADC doses (twice weekly, 4 weeks) or appropriate controls of a non-targeting IgG-SN-38 conjugate or irinotecan. Other groups of animals were treated with the ADC conjugates and RAIT, using RAIT at 60% and 100% of its MTD. The endpoint was time to progress to 3.0 cm3 (TTP), with animals monitored up to 22 weeks. Results: ADCs alone were each able to inhibit tumor growth significantly compared to untreated animals. The specificity of the effect was a dose-dependent and related to antigen saturation at higher doses. When ADC was combined with RAIT, TTP improved significantly and more animals were tumor-free. An effective ADC dose could be combined even with RAIT given at its MTD, achieving enhanced efficacy with minimal additional toxicity. ADC + RAIT treatments were best when RAIT was given 1-2 weeks before, the same day, or within 1 week after the ADC treatment, but delaying RAIT for 2 weeks after ADC treatment reduced efficacy. The same anti-pancreatic mucin antibody, hPAM4, could be used in the combination treatment both as RAIT and as an ADC without losing effectiveness. Conclusions: These studies show the feasibility of using ADC for the treatment of pancreatic cancer, and for combining antibody drug- and radionuclide-targeted therapeutics for improved efficacy with minimal toxicity.

Abstract
OBJECTIVES To document hepatitis C virus (HCV) intrafamilial transmission and assess its relative importance in comparison to other current modes of transmission in the country with the largest HCV epidemic in the world. HCV intrafamilial transmission was defined as HCV transmission among relatives living in the same household. DESIGN Case-control study. Cases were adult patients with acute hepatitis C diagnosed in two 'fever hospitals' of Cairo. Controls were adult patients with acute hepatitis A diagnosed in the same two hospitals, and family members of cases. All consenting household members of cases provided blood for HCV serological and RNA testing. Homology of viral sequences (NS5b region) within households was used to ascertain HCV intrafamilial transmission. Exposures at risk for HCV during the 1-6 months previous to onset of symptoms were assessed in all cases and controls. RESULTS From April 2002 to June 2007, 100 cases with acute hepatitis C, and 678 controls (416 household members and 262 patients with acute hepatitis A) were recruited in the study. Factors independently associated with HCV infection and their attributable fractions (AFs) were the following: having had a catheter (OR=5.0, 95% CI=1.4 to 17.8; AF=6.7%), an intravenous perfusion (OR=5.8, 95% CI=2.5 to 13.3; AF=20.1%), stitches (OR=2.0, 95% CI=1.3 to 6.6; AF=10.7%), gum treatment (OR=3.7, 95% CI=1.1 to 11.9; AF=3.8%) and being illiterate (OR=2.4, 95% CI=1.4 to 4.4). Of the 100 cases, 18 had viraemic HCV-infected household members. Three long-married (>15 years) couples were infected with virtually identical sequences and none of the three index patients reported any exposure at risk, suggesting HCV intra-familial transmission. CONCLUSION While three new HCV infections out of 100 could be linked to intra-familial transmission, parenteral iatrogenic transmission (dental care included) was accountable for 34.6% of these new infections. Thus, the relative contribution of intrafamilial transmission to HCV spread seems to be limited.

Abstract
e22129 Background: ERCC1 is a useful marker of resistance to cisplatin and its analogues. Longer survival was noted in patients with ERCC1 negative expression when treated with platinum. VEGF and its receptor-KDR previously indicated poor prognosis with high tumor cell expression. Methods: From 1998–2008, a retrospective study included 32 patients with advanced NSCLC, where clinical variants as well as the levels of expression of VEGF and VEGFR using rabbit monoclonal Ab (VEGF: A-20, 1:100, SCBT; VEGFR: 55B11, 1:250, cell signaling) and immunohistochemistry for ERCC1 (Mouse monoclonal ab-8F1, Thermo Scientific, 1:200) were measured and co-related to the overall survival of those patients using Cox proportional hazards model. Results: Of the 32 patients, six received non-platinum and twenty six received platinum based regimens either first line or later. Eight patients were females (25%), three were African Americans (9%) and the median age was 62.5 (42–84). Females had a significantly higher overall survival; median survival of 30 months compared to 10.6 months for males (p=0.00089). There was no significant correlation between age and survival (p=0.2). Well differentiated NSCLC of any subtype showed better survival (p=0.04). VEGF low expression correlated with better overall survival (p=0.021). Among the 26 patients who received platinum based regimens, 11 (42%) were ERCC1 negative, 10 had strongly positive ERCC1 expression (39%) and 5 patients had weakly positive ERCC1 expression (19%). ERCC1 negativity was strongly associated with longer survival (p=0.0019) in patients treated with platinum based regimens, where patients treated with the first line platinum had better survival (p=0.034). VEGFR low expression was associated with longer survival in the same group of patients (p=0.013). Caucasians had better overall survival in comparison to African Americans (p=0.007). Higher White blood cell counts and platelet counts were associated with lower survival (p=0.0019 and 0.065 respectively). Conclusion: ERCC1 negativitiy with the first line platinum therapy, VEGF low expression, females, Caucasians as well as the absence of elevation of White blood cells and platelet counts correlate with improved overall survival in advanced NSCLC. No significant financial relationships to disclose.

Abstract
AIM The study compared the accuracy and success rate of two techniques, methylene blue alone versus combined methylene blue and radioactive colloid in sentinel lymph node localisation in the management early breast cancer. METHODS Three hundred and twenty-nine patients with tumours less than 2 cm on ultrasound assessment were prospectively evaluated. One hundred and seventy-three patients (Group A) underwent sentinel lymph node localisation using 1 ml of 1% methylene blue. A combined technique of both methylene blue and radioactive colloid was used in 156 patients (Group B). Application of both was subdermal and subareolar. Sentinel lymph nodes were examined by standard microscopy. Patients underwent breast conservation surgery or mastectomy and sentinel node guided four node axillary sampling+/-clearance. RESULTS In Group A, the sentinel lymph node identification rate was 96.5%. The negative predictive value was 96.3%, with false negative of 3.7% and accuracy of 87.4%. In group B the identification rate for sentinel lymph node was 98.7%, with false negative of 4.1%, negative predictive value of 96%, and accuracy of 83.8%. CONCLUSION Sentinel lymph node localisation using methylene blue or combined dye and radioactive tracer technique predicts the axillary lymph node status in early breast cancer with comparable success rates, accuracy and false negative rates. The combined technique facilitates quicker identification of sentinel lymph node; however the dye technique alone can be used successfully in centres without nuclear medicine facilities.

Abstract
Sensitization can present a virtually insurmountable barrier to kidney transplantation. Ten to twenty percent of patients on waiting lists for renal transplantation have developed broadly reactive cytotoxic antibodies against HLA antigens caused by pregnancy, blood transfusion, or a prior failed allograft. These sensitized end-stage renal disease patients often wait more than 5 years for a kidney to be offered. Potent immunosuppressives, plasma exchange and/or immunoadsorption have been used but the risk of infection limited their use. Some reports, have demonstrated in small numbers of patients the use of Intravenous Immunoglobulin (IVIG) as potential modality for the treatment of these sensitized patients. The goal of this study was to investigate the extent of the efficacy and to assess the utility of this modality of treatment on a relatively larger number of patients. The study included 11 patients with end stage renal disease who were waiting for living related renal allotransplantation. All patients had persistently positive crossmatches with their living related donors and PRA titer >/=20%. They received IVIG for a period of two weeks and a total of 6 doses. None of these patients, however, attained significant suppression of anti-HLA antibodies titer or a negative crossmatch reaction. We found that IVIG alone couldn't effectively inhibit preformed anti-HLA antibodies to allow successful renal transplantation.

Abstract
Historically, hysterectomy is one of the oldest gynecologic operations, dating back to the 1840s. Currently, it is the most common gynecologic operation performed and is associated with marked improvement in the patients' quality of life. It is widely considered a safe procedure with an extremely low mortality rate (<0.1%). The majority of hysterectomies are done abdominally, with the vast majority being total abdominal hysterectomies. The effect of hysterectomy on pelvic floor function has been a subject of long debate. Various studies have reached different and rather contradictory results. Most of these studies lack stringent methodologic standards, being retrospective, observational, or uncontrolled. A recent excellent study assessed the effect of abdominal hysterectomy on pelvic floor function as 1 functional unit and concluded that both total and subtotal abdominal hysterectomies have no detrimental effect on the pelvic floor function up to 1 year postoperatively.

Abstract
Phyllodes tumour (PT) is a rare neoplasm of the female breast that resembles fibroadenoma but occurs in an older age group. We retrospectively reviewed the medical records of 30 women who were treated for phyllodes tumour in our centre. Histological examination was performed by an experienced breast pathologist in all cases and tumours were classified as benign, border line malignant or malignant according to standard histological criteria. The mean age at diagnosis was 49 years (range: 19-80 years). Twenty-one (70%) of 30 tumours were benign and 9 (30%) were malignant (n=7) or borderline malignant (n=2). The mean tumour size was 46 mm (range: 20-100 mm). The final microscopic margins contained tumour in 13 (43%) of 30 cases and were free of tumour in 17 (57%) of 30 patients. After a median follow-up period of 6 years (range: 6 months-20 years), the tumour recurred locally in 5 (17%) patients. One patient had six local recurrences over an 18-year period. Local recurrences were more frequently observed in patients with malignant tumours compared with those with benign lesions (33% versus 10%). However, this association failed to reach statistical significance. There was no association between local recurrence, patient age, tumour size or positive microscopic margins. There was one death (3%) associated with a completely excised malignant tumour. The present study suggests that histological type and margins do not accurately predict the clinical course of PT and that there is a need to identify novel biological markers that more accurately predict the behaviour of this rare neoplasm.
