Abstract
Ki-67 is a nuclear protein associated with proliferation, and a strong potential biomarker in breast cancer, but is not routinely measured in current clinical management owing to a lack of standardization. Digital image analysis (DIA) is a promising technology that could allow high-throughput analysis and standardization. There is a dearth of data on the clinical reliability as well as intra- and interalgorithmic variability of different DIA methods. In this study, we scored and compared a set of breast cancer cases in which manually counted Ki-67 has already been demonstrated to have prognostic value (n = 278) to 5 DIA methods, namely Aperio ePathology (Lieca Biosystems), Definiens Tissue Studio (Definiens AG), Qupath, an unsupervised immunohistochemical color histogram algorithm, and a deep-learning pipeline piNET. The piNET system achieved high agreement (interclass correlation coefficient: 0.850) and correlation (R = 0.85) with the reference score. The Qupath algorithm exhibited a high degree of reproducibility among all rater instances (interclass correlation coefficient: 0.889). Although piNET performed well against absolute manual counts, none of the tested DIA methods classified common Ki-67 cutoffs with high agreement or reached the clinically relevant Cohen's κ of at least 0.8. The highest agreement achieved was a Cohen's κ statistic of 0.73 for cutoffs 20% and 25% by the piNET system. The main contributors to interalgorithmic variation and poor cutoff characterization included heterogeneous tumor biology, varying algorithm implementation, and setting assignments. It appears that image segmentation is the primary explanation for semiautomated intra-algorithmic variation, which involves significant manual intervention to correct. Automated pipelines, such as piNET, may be crucial in developing robust and reproducible unbiased DIA approaches to accurately quantify Ki-67 for clinical diagnosis in the future.

Abstract
COVID-19 is reported as an extremely contagious disease with common symptoms of fever, dry cough, sore throat, and tiredness. The published literature on incidence and gender-wise prevalence of COVID-19 is scarce in Pakistan. Therefore, the present study was designed to compare the distribution, incubation period and mortality rate of COVID-19 among the male and female population of district Attock. The data were collected between 01 April 2020 and 07 December 2020 from the population of district Attock, Pakistan. A total of 22,962 individuals were screened and 843 were found positive for RT-qPCR for SARS-CoV-2. The confirmed positive cases were monitored carefully. Among the positive cases, the incidence of COVID-19 was 61.7% among males and 38.2% among females. The average recovery period of males was 18.89±7.75 days and females were 19±8.40 days from SARS-CoV-2. The overall mortality rate was 8.06%. The death rate of male patients was significantly higher (P<0.05) compared to female patients. Also, the mortality rate was higher (P<0.05) in male patients of 40-60 years of age compared to female patients of the same age group. Moreover, the mortality rate significantly increased (P<0.05) with the increase of age irrespective of gender. In conclusion, the incidence and mortality rate of COVID-19 is higher in males compared to the female population. Moreover, irrespective of gender the mortality rate was significantly lower among patients aged <40 years.

Abstract
The Indian crested porcupine (Hystrix indica) is a vertebrate pest of agricultural lands and forest. The study was aimed to report the damage to local crops by the Indian crested porcupine (Hystrix indica) in the Muzaffarabad District. A survey was conducted to identify the porcupine-affected areas and assess the crop damage to the local farmers in district Muzaffarabad Azad Jammu and Kashmir (AJK) from May 2017 to October 2017. Around 19 villages were surveyed, and a sum of 191 semi-structured questionnaires was distributed among farmers. Crop damage was found highest in village Dhanni where a porcupine destroyed 175 Kg/Kanal of the crops. Regarding the total magnitude of crop loss, village Danna and Koomi kot were the most affected areas. More than half (51.8%) of the respondents in the study area suffered the economic loss within the range of 101-200$, and (29.8%) of the people suffered losses in the range of 201-300$ annually. Among all crops, maize (Zea mays) was found to be the most damaged crop ranging between 1-300 Kg annually. In the study area, porcupine also inflicted a lot of damages to some important vegetables, including spinach (Spinacia oleracea), potato (Solanum tuberosum) and onion (Allium cepa). It was estimated that, on average, 511Kg of vegetables are destroyed by porcupine every year in the agricultural land of Muzaffarabad. It was concluded that the Indian crested porcupine has a devastating effect on agriculture which is an important source of income and food for the local community. Developing an effective pest control strategy with the help of the local government and the Wildlife department could help the farmers to overcome this problem.

Abstract
Oral diseases caused by various microorganisms are common around the world. Scientific research has now been focusing on novel medicines to overcome bacterial resistance and antibiotics side effects; therefore, the current study was designed to assess the efficacy of certain antibiotics, toothpaste, and medicinal plant extracts (Ajuga bracteosa and Curcuma longa) versus the bacterial pathogens isolated from the human oral cavity. A total of 130 samples were collected from Khyber Teaching Hospital Peshawar, Pakistan, among those 27 species isolated, and eight bacterial species were identified from the samples. Among all the bacterial species, Staphylococcus aureus (29.62%) and Proteus mirabilis (22.2%) were found to be more prevalent oral pathogens. In comparison, the least pervasive microbes were Proteus vulgaris, Shigella sonnei, Escherichia coli and Aeromonas hydrophila. The study also suggested that dental problems were more prevalent in males (41-50 years of age) than females. Among the eight antibiotics used in the study, the most promising results were shown by Foxicillin against A. hydrophila. The survey of TP1 revealed that it showed more potent antagonist activity against Proteus vulgaris as compared TP2 and TP3 that might be due to the high content of fluoride. The Curcuma longa showed more significant activity than Ajuga bracteosa (Stem, leaves and root) extracts. The data obtained through this study revealed that antibiotics were more effective for oral bacterial pathogens than toothpaste and plant extracts which showed moderate and low activity, respectively. Therefore, it is suggested that the active compounds in individual medicinal plants like Curcuma longa and Ajuga bracteosa could replace the antibiotics when used in daily routine as tooth cleansers or mouth rinses.

Abstract
BACKGROUND We have observed an increasing number of patients referred to the Scottish Photobiology Service (SPS), who were later diagnosed with actinic folliculitis (AF) and had positive phototesting results. Treatment options for AF are limited, with only a few reports in the literature. The use of prophylactic narrowband ultraviolet B (NB-UVB) phototherapy for AF has not previously been described, and we report on this for the first time. AIM To analyse the clinical characteristics, phototesting results and responses to treatment for patients with AF diagnosed by the SPS. METHODS We undertook a retrospective review over 10 years of all case notes of patients who were assessed and diagnosed with AF through the SPS, based at the Photobiology Unit, Dundee, UK. RESULTS All 10 patients were women. Mean age of onset was 25 years and mean time to referral for investigation was 7 years. The commonest site involved was the face, with the main clinical feature being monomorphic pustules appearing after sunlight exposure. The eruption could be provoked with iterative doses of broadband UVA irradiation in five patients. All patients were offered photoprotective advice and prophylactic NB-UVB phototherapy. Five patients proceeded with phototherapy; four of these completed the desensitization course and all four reported either a delay in symptom onset or total prevention of rash induction, with complete efficacy of desensitization maintained for 3 years in one patient. CONCLUSION We demonstrate the successful use of UVA provocation testing as a diagnostic tool in AF. Additionally, we recommend the use of prophylactic NB-UVB phototherapy in AF as an effective and well-tolerated approach.

Abstract
BACKGROUND We evaluated the effect of cardiac resynchronization therapy (CRT) on septal perfusion and thickening at 6 months post implantation assessed on Tc99m-MIBI Gated myocardial perfusion SPECT (GMPS).We also studied the association of change in septal perfusion and thickening with primary outcome defined as at least one [improvement in ≥1NYHA class, left ventricular ejection fraction (LVEF) by ≥ 5%, reduction of end-systolic volume (ESV) by ≥ 15%, and improvement ≥ 5 points in Minnesota living with heart failure questionnaire (MLHFQ)]. METHOD One hundred and five patients underwent clinical and GMPS evaluation before and at 6 months post CRT. RESULT Post CRT there was significant improvement in mean normalized septal perfusion uptake and in septal thickening (P value = 0.001, both). There was no significant relation between improvement in septal perfusion and primary outcome. However, improvement in septal thickening was statistically significant with favorable primary outcome (P = 0.001).There was no significant correlation between improvement of septal perfusion and improvement in LVEF, reduction in End diastolic volume (EDV), ESV, and Left ventricular Dyssynchrony (LVD). But, there was significant correlation between improvement of septal thickening and these parameters. CONCLUSION Improvement in septal thickening was associated with reverse remodeling, improvement in LVEF, and reduction of LVD.

Abstract
Background: Pleural tuberculosis (TB) diagnosis is challenging due to paucibacillary disease. Diagnostic accuracy of GenoType MTBDRplus Line Probe Assay (MTBDRplus) has been evaluated in this study for pleural TB diagnosis.Objective: To evaluate diagnostic accuracy of MTBDRplus for pleural TB diagnosis compared to clinical and microbiological diagnosis.Methods: This prospective study was conducted at the Aga Khan University, Pakistan. Pleural fluid from 203 suspected pleural TB patients was collected and tested for smear, culture and MTBDRplus. Diagnostic accuracy of MTBDRplus was determined using clinical diagnosis and culture as the gold standard.Results: Out of 203 TB suspect patients, MTBDRplus, culture and smear were positive in 14 (6. 9%), 27 (13.3%) and 4 (1.9%) cases, respectively. A total of 106/203 patients (27 culture positive and 79 culture negative) successfully completed TB treatment. Considering clinical diagnosis as gold standard, sensitivity of MTBDRplus was 13.2%; 95% CI (7.4-21.2%) and specificity was 100%; 95% CI (96.1-100%). The sensitivity and specificity of MTBDRplus in culture positive samples were 44.4%; 95% CI (25.5-64.7%) and 98.9%; 95% CI (95.9-99.9%), respectively. Excluding indeterminate results, MTBDRplus accurately detected isoniazid sensitivity in 5/6 and rifampicin sensitivity in 6/6 cases.Conclusion: MTBDRplus had a low sensitivity of 13.2% in clinically diagnosed and 44% in culture-confirmed pleural TB patients and therefore could not be included in most diagnostic algorithms. Due to a higher sensitivity than smear, MTBDRplus may have a role in tuberculous pleural effusion diagnosis if it is positive pending culture results and pleural biopsy.

Abstract
Introduction Esophageal variceal band ligation (EVBL) is the best form of treatment for variceal bleeding. The frequency of EVBL for the eradication of esophageal varices has no consensus. We evaluated the number and interval of EVBL sessions required for the obliteration of esophageal varices. Methods Esophagogastric varices were treated endoscopically with band ligation on initial presentation and then every after three weeks till the obliteration of the varices. Endoscopic band ligation consists of placing rubber elastic bands on large varices. Frequencies were calculated for qualitative variables and mean ± standard deviations for continuous variables. Results A total of 107 cases with esophagogastric varices were enrolled. Out of them, seven patients with small esophageal varices and large fundal varices were excluded. The remaining 100 with large esophageal varices had EVBL performed. The second session of EVBL was done in 46 patients with large esophageal varices. The third session of EVBL for the obliteration of esophageal varices required in 20 patients with large esophageal varices and the fourth session was required in only two patients. The total sessions required for the complete obliteration for esophageal varices were 2±1. Only one patient developed post-EVBL bleeding one week after band ligation. Conclusion Esophageal variceal ligation was a safe and well-tolerated procedure performed at three-week intervals in patients with large esophageal varices. On average, two to three sessions of EVBL are required for the complete obliteration of esophageal varices.

Abstract
Background It is estimated that approximately 10 million individuals in Pakistan are infected with hepatitis C virus (HCV). Historically, it was very difficult not just to cure but even treat HCV as available options did not have desirable outcomes. However, the approval of directly acting antiviral (DAA) drugs has revolutionized treatment and management. These are specific proteases and polymerase inhibitors with profound capability for accomplishing elimination and overtime eradication of the virus. Objective The aim of this study was to evaluate the efficacy and safety of sofosbuvir (SOF) in combination with ribavirin (RIB) for the treatment of chronic hepatitis C virus with genotype 3. Materials and methods This prospective observational study was conducted at the gastroenterology section of Medical Unit IV, Jinnah Post-graduate Medical Center, Karachi and Medical Unit II, Dow University of Health Sciences, Ojha Campus, Karachi from January 2016 to December 2016. Patients aged 18 years or older of either gender having chronic active HCV infection as demonstrated by a positive Anti-HCV (ELISA) test and a qualitative polymerase chain reaction (PCR) analysis along with genotype analysis showing only type 3 were inducted into the study. Treatment was initiated with either 12-week or 24-week regimen of SOF 400 mg once daily along with weight-adjusted RIB orally. Successful treatment was indicated by the elimination of the virus, i.e., undetectable viral load/levels by PCR qualitative analysis. Rapid virological response (RVR), end of treatment response (ETR), and sustained virological response (SVR) were defined as the undetectable viral load at four, 12, and 24 weeks, respectively. Results A total of 300 patients were inducted into the study, predominantly female (57%). The mean age of presentation was 41.14 ± 11.48, and most (70.33%) were treatment naïve. The mean alanine transaminase (ALT), aspartate aminotransferase (AST), and gamma-glutamyl transferase (GGT) levels at presentation were 41.89 ± 46.23 IU/l, 68.57 ± 83.62 IU/l, and 54.52 ± 77.57 IU/l, respectively. ALT, AST, and GGT levels at 24 weeks were 33.84 ± 13.60 IU/l, 32.44 ± 16.16 IU/l, and 37.59 ± 22.41 IU/l, respectively, showing significant improvement. ETR was achieved in 99.1% (209) treatment-naïve patients and 98.9% (88) treatment-experienced patients. SVR rates were almost similar with 98% (208) achieving it in the treatment-naïve group and 96.6% (86) achieving it in the treatment-experienced group. Conclusion SOF in combination with RIB is safe and remarkably efficacious in the treatment of chronic HCV, genotype 3. Not only is this regimen associated with the elimination of viral replication but it also improved transaminase levels. Outcomes are rarely, if ever, affected by previous use of antiviral medications.

Abstract
For Pakistani banks to remain competitive in this 21st century, they have to adopt and excel in practices that have brought significant competitive advantages to firms worldwide. Among these practices, lean management has played a significant role. There is a need to develop a systematic approach to access up to what extent firms are adopting lean practices. The objective of this research is to measure the level of adoptions of lean practices in banking sector in Pakistan. Face to face structured interviews were conducted and our findings suggest that banks are not implementing lean practices in true spirit. To implement lean practices holistically, bank employees should understand the philosophy of lean.

Abstract
Background Hepatitis B virus (HBV) infection is a serious health problem in Pakistan. In view of the serious socioeconomic consequences, identifying patient characteristics and the current treatment for the disease will enhance HBV regulation and its medical management. Aims To describe the epidemiology, clinical characteristics, and current management status of patients infected by HBV. Methods We undertook an observational, cross-sectional, and epidemiological study at the Jinnah Postgraduate Medical Centre, Karachi, during the period from January 2014 to November 2017. Male and female patients of any age and with documentation for an HBV infection were eligible for inclusion in the study. An HBV infection was defined as a positive hepatitis B surface antigen test. Results A total of 500 patients were analyzed. The mean age at presentation was 29.86±13.68 years. The majority of the patients (25.6%) were ethnically Sindhi followed by Pathan (24.4%), indicating a high prevalence among the rural-based population of Pakistan. The mean duration of the disease was 3.51±4.46 years. The most common cause for the spread was positive family history (40.4%) followed by roadside barbers (30.0%). Most patients were Child-Pugh (CP) class A (84.6%) and the median Modified End-Stage Liver Disease (MELD) score was 7. Upper gastrointestinal bleeding was the most frequent hepatic complication (6.2%). Antiviral medications had been received by 18.6% of patients previously. Peg-interferon (6.0%) was the major antiviral medication prescribed to treatment-experienced patients. Conclusions This observational, real-life study has identified some gaps between clinical practice and guideline recommendations in Pakistan. To achieve better health outcomes, several improvements, such as disease monitoring and optimizing antiviral regimens, should be made to improve disease management.

Abstract
Evofosfamide (TH-302) is a clinical-stage hypoxia-activated prodrug of a DNA-crosslinking nitrogen mustard that has potential utility for human papillomavirus (HPV) negative head and neck squamous cell carcinoma (HNSCC), in which tumor hypoxia limits treatment outcome. We report the preclinical efficacy, target engagement, preliminary predictive biomarkers and initial clinical activity of evofosfamide for HPV-negative HNSCC. Evofosfamide was assessed in 22 genomically characterized cell lines and 7 cell line-derived xenograft (CDX), patient-derived xenograft (PDX), orthotopic, and syngeneic tumor models. Biomarker analysis used RNA sequencing, whole-exome sequencing, and whole-genome CRISPR knockout screens. Five advanced/metastatic HNSCC patients received evofosfamide monotherapy (480 mg/m2 qw × 3 each month) in a phase 2 study. Evofosfamide was potent and highly selective for hypoxic HNSCC cells. Proliferative rate was a predominant evofosfamide sensitivity determinant and a proliferation metagene correlated with activity in CDX models. Evofosfamide showed efficacy as monotherapy and with radiotherapy in PDX models, augmented CTLA-4 blockade in syngeneic tumors, and reduced hypoxia in nodes disseminated from an orthotopic model. Of 5 advanced HNSCC patients treated with evofosfamide, 2 showed partial responses while 3 had stable disease. In conclusion, evofosfamide shows promising efficacy in aggressive HPV-negative HNSCC, with predictive biomarkers in development to support further clinical evaluation in this indication.

Abstract
Objective: The aim of this study was to evaluate the accuracy of “X- ray examination of surgically resected specimen‘‘ in assessing complete local excision (CLE). Materials and Methods: In this retrospective cross sectional study, data were collected for all female breast cancer cases who underwent breast-conserving surgery after needle localization of mammographically visible disease. Males, patients with mammographically invisible disease and cases with benign or inconclusive histopathology, those undergoing modified radical mastectomy and individuals with dense breast parenchyma were excluded. We evaluated radiography of resected specimens to assess margin spiculation, distance of mass/microcalcification from the excised margin, presence of a mass, and presence of any adjacent microcalcification, Other features including mass size, nuclear grade and patient’s age were also recorded and all were analyzed for any association with CLE. Results: Absence of adjacent microcalcification and the presence of a mass on radiographs showed significant associations with CLE, but no links were evident with other features. Specimen radiography was found to be a sufficient tool to predict CLE with a positive predictive value of 83.3%, a sensitivity of 80.7% and a specificity of 81%. Conclusion: Specimen radiography is an important and sensitive tool to predict CLE.

Abstract
BACKGROUND Breast malignancies are one of the leading causes of deaths in females worldwide. There are a number of risk factors associated with breast cancer but in Karachi Pakistan there are insufficient data available. MATERIALS AND METHODS A case control study was conducted on females in age group between 30-80 years. This study was accomplished by retrospective data collection in Aga Khan University Hospital Karachi, Pakistan. A total of 108 females with primary malignancy of breast were included along with 108 matched controls. Relationship of various factors with disease was studied using logistic regression to calculate odds ratios with 95 % confidence intervals. RESULTS A total of 14 variables were analyzed and based on and 7 were found to be risk factors: old age, family history of breast cancer, family history of other carcinomas, personal history of breast carcinoma, early age of menarche, older age of mother at first delivery and lower number of children. Five factors, parity, breast feeding, history of oral contraceptive pills intake, past history of oophorectomy and hysterectomy showed protective associations. One variable, use of hormonal replacement therapy, showed a controversial link and one other, marital status, was not significant in this study. CONCLUSIONS It is concluded that most of the well-known risk factors for breast cancer are also associated with the disease in the female population of Karachi, Pakistan. High risk patients should be the focus with the help of this study so that screening can be more effective for early diagnosis before clinically evident breast malignancy.

Abstract
BACKGROUND Chronic intestinal pseudo-obstruction (CIPO) is characterized by dilatation of the bowel lumen and abnormal motility. In this study, we aimed to quantify small bowel dysmotility in CIPO using a validated pan-intestinal motility assessment technique based on motion capture magnetic resonance imaging (MRI) compared to normal controls. In addition, we explored if motility responses of CIPO patients to neostigmine challenge differed from healthy volunteers. METHODS Twenty healthy volunteers (mean age 28, range 22-48) and 11 CIPO patients (mean age 47, range 19-90) underwent MRI enterography to capture global small bowel motility. Eleven controls and seven CIPO patients further underwent a randomized placebo-controlled crossover study of either intravenous neostigmine (0.5 mg) or saline with motility MRI repeated at a mean of 3 weeks. Motility was quantified in regions of interest placed to encompass the whole small bowel volume using a validated, postprocessing technique to give a global motility index in arbitrary units (AU). Baseline and stimulated motility was compared using Wilcoxon rank-sum paired T-tests. KEY RESULTS Baseline global small bowel motility was significantly lower in CIPO patients compared to controls (mean 0.25 AU vs 0.35 AU, p < 0.001). Motility in both groups increased significantly after neostigmine (0.06 AU increase, p = 0.016 in CIPO and 0.06 AU increase, p = 0.002 in controls). Three patients with scleroderma had a reduced response to neostigmine. CONCLUSIONS & INFERENCES Global small bowel motility in CIPO patients is significantly lower than controls and response to the pro-kinetic agent neostigmine may differ according to disease phenotype. Software-quantified bowel motility using cine MRI has potential as a future tool to investigate enteric dysmotility.

Abstract
Previous studies have indicated that sodium salicylate (SS) can cause hearing abnormalities through affecting the central auditory system. In order to understand central effects of the drug, we examined how a single intraperitoneal injection of the drug changed the level of subunits of the type-B γ-aminobutyric acid receptor (GABAB receptor) in the rat's inferior colliculus (IC). Immunohistochemical and western blotting experiments were conducted three hours following a drug injection, as previous studies indicated that a tinnitus-like behavior could be reliably induced in rats within this time period. Results revealed that both subunits of the receptor, GABABR1 and GABABR2, reduced their level over the entire area of the IC. Such a reduction was observed in both cell body and neuropil regions. In contrast, no changes were observed in other brain structures such as the cerebellum. Thus, a coincidence existed between a structure-specific reduction in the level of GABAB receptor subunits in the IC and the presence of a tinnitus-like behavior. This coincidence likely suggests that a reduction in the level of GABAB receptor subunits was involved in the generation of a tinnitus-like behavior and/or used by the nervous system to restore normal hearing following application of SS.

Abstract
STUDY QUESTION Do women who have diabetes before menopause have their menopause at an earlier age compared with women without diabetes? SUMMARY ANSWER Although there was no overall association between diabetes and age at menopause, our study suggests that early-onset diabetes may accelerate menopause. WHAT IS KNOWN ALREADY Today, more women of childbearing age are being diagnosed with diabetes, but little is known about the impact of diabetes on reproductive health. STUDY DESIGN, SIZE, DURATION We investigated the impact of diabetes on age at natural menopause (ANM) in 258 898 women from the European Prospective Investigation into Cancer and Nutrition (EPIC), enrolled between 1992 and 2000. PARTICIPANTS/MATERIALS, SETTING, METHODS Determinant and outcome information was obtained through questionnaires. Time-dependent Cox regression analyses were used to estimate the associations of diabetes and age at diabetes diagnosis with ANM, stratified by center and adjusted for age, smoking, reproductive and diabetes risk factors and with age from birth to menopause or censoring as the underlying time scale. MAIN RESULTS AND THE ROLE OF CHANCE Overall, no association between diabetes and ANM was found (hazard ratio (HR) = 0.94; 95% confidence interval (CI) 0.89-1.01). However, women with diabetes before the age of 20 years had an earlier menopause (10-20 years: HR = 1.43; 95% CI 1.02-2.01, <10 years: HR = 1.59; 95% CI 1.03-2.43) compared with non-diabetic women, whereas women with diabetes at age 50 years and older had a later menopause (HR = 0.81; 95% CI 0.70-0.95). None of the other age groups were associated with ANM. LIMITATIONS, REASONS FOR CAUTION Strengths of the study include the large sample size and the broad set of potential confounders measured. However, results may have been underestimated due to survival bias. We cannot be sure about the sequence of the events in women with a late age at diabetes, as both events then occur in a short period. We could not distinguish between type 1 and type 2 diabetes. WIDER IMPLICATIONS OF THE FINDINGS Based on the literature, an accelerating effect of early-onset diabetes on ANM might be plausible. A delaying effect of late-onset diabetes on ANM has not been reported before, and is not in agreement with recent studies suggesting the opposite association. STUDY FUNDING/COMPETING INTERESTS The coordination of EPIC is financially supported by the European Commission (DG-SANCO) and the International Agency for Research on Cancer.

Abstract
Over the last few decades, more healthcare professionals have faced investigation into complaints about medical care and healthcare outcomes (Department of Health 2003). With increasing medical negligence cases being brought against doctors, it is time to carefully consider the implications of such actions to ensure appropriate safeguards (Ferner and McDowell 2006). At a time when the culture of 'no win, no fee' is rampant, the jobbing frontline doctor is on the back-foot trying to untangle the legalities of a malpractice claim (Ferner and McDowell 2006). Reassuringly, the numbers of doctors referred to the GMC or having to face legal procedures or claims for compensation are still very small (National Audit Office 2001). An essential issue for all doctors is having appropriate indemnity cover in the event that their practice is challenged. The opt-out for the European Working Time Regulations (EWTR) has caused further confusion as to what is covered for junior doctors by individual indemnity policies and the employer's liability scheme. Recently, the RCOG Trainees committee and the BMA Junior Doctors Association issued a joint advice regarding this issue (RCOG 2010). In this paper, we consider the differences in cover provided by the employer's liability scheme, individual professional indemnity schemes and the role of professional bodies. We also seek to clarify the understanding of these surrounding EWTR and the voluntary opt-out clause and provide up-to-date information on medico-legal issues and protection schemes regarding legal liabilities.

Abstract
The type B γ-aminobutyric acid receptor (GABA(B) receptor) is an important neurotransmitter receptor in the midbrain auditory structure, the inferior colliculus (IC). A functional GABA(B) receptor is a heterodimer consisting of two subunits, GABA(B)R1 and GABA(B)R2. Western blotting and immunohistochemical experiments were conducted to examine the expression of the two subunits over the IC including its central nucleus, dorsal cortex, and external cortex (ICc, ICd, and ICx). Results revealed that the two subunits existed in both cell bodies and the neuropil throughout the IC. The two subunits had similar regional distributions over the IC. The combined level of cell body and neuropil labeling was higher in the ICd than the other two subdivisions. Labeling in the ICc and ICx was stronger in the dorsal than the ventral regions. In spite of regional differences, no defined boundaries were formed between different areas. For both subunits, the regional distribution of immunoreactivity in the neuropil was parallel to that of combined immunoreactivity in the neuropil and cell bodies. The density of labeled cell bodies tended to be higher but sizes of cell bodies tended to be smaller in the ICd than in the other subdivisions. No systematic regional changes were found in the level of cell body immunoreactivity, except that GABA(B)R2-immunoreactive cell bodies in the ICd had slightly higher optic density (OD) than in other regions. Elongated cell bodies existed throughout the IC. Many labeled cell bodies along the outline of the IC were oriented in parallel to the outline. No strong tendency of orientation was found in labeled cell bodies in ICc. Regional distributions of the subunits in ICc correlated well with inputs to this subdivision. Our finding regarding the contrast in the level of neuropil immunoreactivity among different subdivisions is consistent with the fact that the GABA(B) receptor has different pre- and postsynaptic functions in different IC regions.

Abstract
BACKGROUND Breast cancer detected by screening has an unexplained prognostic advantage beyond stage shift compared with cancers detected clinically. The aim was to investigate biological factors in invasive breast cancer, with reference to mode of detection and rate of death from breast cancer. METHODS Histology, oestrogen receptor α and β, progesterone receptor, human epidermal growth factor receptor (HER) 2, cyclin D1, p27, Ki-67 and perinodal growth were analysed in 466 tumours from a prospective cohort, the Malmö Diet and Cancer Study. Using logistic regression, odds ratios were calculated to investigate the relationship between tumour characteristics and mode of detection. The same tumour factors were analysed in relation to standard prognostic features. Death from breast cancer was analysed using Cox regression with adjustments for standard tumour factors; differences following adjustment were analysed by means of Freedman statistics. RESULTS None of the biological tumour characteristics varied with mode of detection of breast cancer. After adjustment for age, tumour size, axillary lymph node involvement (ALNI) and grade, women with cancer detected clinically had an increased risk of death from breast cancer (hazard ratio 2·48, 95 per cent confidence interval 1·34 to 4·59), corresponding to a 37·2 per cent difference compared with the unadjusted model. Additional adjustment for biological tumour factors studied caused only minor changes. CONCLUSION None of the biological tumour markers investigated explained the improved prognosis in breast cancer detected by screening. None of the factors was related to ALNI, suggesting that other mechanisms may be responsible for tumour spread.

Abstract
BACKGROUND Although many low-penetrant genetic risk factors for breast cancer have been discovered, knowledge about the effect of multiple risk alleles is limited, especially in women <50 years. We therefore investigated the association between multiple risk alleles and breast cancer risk as well as individual effects according to age-approximated pre- and post-menopausal status. METHODS Ten previously described breast cancer-associated single-nucleotide polymorphisms (SNPs) were analysed in a joint European biobank-based study comprising 3584 breast cancer cases and 5063 cancer-free controls. Genotyping was performed using MALDI-TOF mass spectrometry, and odds ratios were estimated using logistic regression. RESULTS Significant associations with breast cancer were confirmed for 7 of the 10 SNPs. Analysis of the joint effect of the original 10 as well as the statistically significant 7 SNPs (rs2981582, rs3803662, rs889312, rs13387042, rs13281615, rs3817198 and rs981782) found a highly significant trend for increasing breast cancer risk with increasing number of risk alleles (P-trend 5.6 × 10(-20) and 1.5 × 10(-25), respectively). Odds ratio for breast cancer of 1.84 (95% confidence interval (CI): 1.59-2.14; 10 SNPs) and 2.12 (95% CI: 1.80-2.50; 7 SNPs) was seen for the maximum vs the minimum number of risk alleles. Additionally, one of the examined SNPs (rs981782 in HCN1) had a protective effect that was significantly stronger in premenopausal women (P-value: 7.9 × 10(-4)). CONCLUSION The strongly increasing risk seen when combining many low-penetrant risk alleles supports the polygenic inheritance model of breast cancer.

Abstract
BACKGROUND The association between cancer and non-caseating granulomas is controversial. The aim of this study is to describe the clinical characteristics and outcome of a cohort of patients found to have non-caseating granulomas following the diagnosis of cancer. METHODS Retrospective review of medical records. RESULTS There were 30 patients with non-caseating granulomas following the diagnosis of cancer. There were 21 females and 14 patients were African Americans. Breast, lung, and head and neck cancers were the most common malignancies. The time between the diagnosis of cancer and non-caseating granulomas was a mean of 27.6 months (range 3 to 245 months). New mediastinal lymphadenopathy were present in 29 patients and pulmonary infiltrates or nodules were detected in 15 patients. All patients who underwent FDG-PET scan (n=18) had FDG avid findings with a mean SUV of 6.8 (range 2.8-19.4). Non-caseating granulomas were diagnosed by mediastinoscopy (12 patients), EBUS-FNA (6 patients), surgical thoracic biopsy (3 patients), transbronchial biopsy (2 patients), and other biopsies (7 patients). Patients were followed for a mean of 32.7 months (range 6-98 months) and 3 patients developed recurrence of the primary cancer. CONCLUSION Non-caseating granulomas should be considered in patients with cancer who develop lymphadenopathy or pulmonary nodules. Recurrence of cancer should not always be assumed, and tissue diagnosis is essential.

Abstract
Congenital coronary sinus anomalies are unusual and they rarely coexist with accessory atrio-ventricular pathways. These anomalies are generally symptomatic; however they can cause difficulty in mapping. The association between accessory pathway and coronary sinus anomalies may suggest an embryological link. Here, we report on a male patient with an accessory conducting pathway in the coronary sinus, leading to Wolff-Parkinson-White (WPW) syndrome.

Abstract
The changing pattern in hepatitis C virus (HCV) clades overtime is not well known in Pakistan. To find out the changing pattern of different HCV clades over time in this country 22,125 patients were genotyped and tracked for a period of 11 years (2000-2010). A changing pattern in HCV clades was seen in this region during the study period. Sub-clade 3a remained the dominant sub-clade circulating in different areas of the country in the study era. HCV sub-clade 3a demonstrated significantly high correlation with time (p < 0.05) whereas undetermined clades were seen with statistically non-significant correlation with time (years). All the other clades showed negative correlation with time. In general a significant decline was observed in the percentages of HCV clades 2, 4, 5 and 6 (p < 0.001). Among sub-clades, HCV 1a, 2c, 2b and 3b significantly decreased overtime (p < 0.05), while an increase has been observed for HCV 3a sub-clade and mixed clades (p <0.001). The ratio of undetermined clades remained constant over the study period. In conclusion, a changing pattern of HCV clades was observed over the 11-year study period, and this changed pattern might have direct impact on HCV disease outcome.
