    Aim of the study was to audit patients who had undergone parathyroidectomy in University of Malaya Medical Centre (UMMC), and compare surgical outcomes with that in the literature. Data on demography, aetiology, surgical indications, pre-operative localization, surgery and complications was obtained retrospectively from medical records of patients undergoing parathyroidectomy between 1st October 2000 to 31st October 2005. Twelve patients were identified. Mean age was 50.6 years. Sixty seven percent were females. The ratio of Chinese, Malays and Indians was 7:4:1. Most surgeries were performed in the last two years (91.7%). Aetiology was mainly tertiary hyperparathyroidism (83%). All patients had pre-operative ultrasound localization. Half underwent total parathyroidectomy without autotransplantation. There were no re-do operations. Mean duration of surgery was 1.96 hours. All patients had abnormal calcium levels at some point following surgery, but 90% were normocalcaemic at last follow up. Other complications were recurrent laryngeal nerve injury (one) and wound infection (one). There were no peri-operative mortalities. The mean duration of hospital stay was 7.75 days (range 3-17 days). The median duration of follow-up was 11 months. The outcome of parathyroidectomy in UMMC is satisfactory with few major complications. Despite this, intensive effort is needed to further improve these results to match those obtained in specialist endocrine centres.

    BACKGROUND: Faecal incontinence (FI) is not a common presenting complaint in Malaysia, and little has been published on this topic. Since it is a treatable condition, a greater understanding of factors contributing to healthseeking behaviour is needed in order to plan effective provision of services.

    METHODS: A survey of 1000 patients and accompanying relatives, visiting general surgical and obstetrics and gynaecology clinics for matters unrelated to FI, was conducted at University Malaya Medical Centre between January 2009 and February 2010. A follow-up regression analysis of the 83 patients who had FI, to identify factors associated with health-seeking behaviour, was performed. Variables identified through univariate analysis were subjected to multivariate analysis to determine independence. Reasons for not seeking treatment were also analysed.

    RESULTS: Only eight patients (9.6%) had sought medical treatment. On univariate analysis, the likelihood of seeking treatment was significantly higher among patients who had more severe symptoms (OR 30.0, p=0.002), had incontinence to liquid stool (OR 3.83, p=0.002) or when there was an alteration to lifestyle (OR: 17.34; p<0.001). Nevertheless, the only independently-associated variable was alteration in lifestyle. Common reasons given for not seeking treatment was that the condition did not affect patients' daily activities (88.0%), "social taboo" (5.3%) and "other" reasons (6.7%).

    CONCLUSIONS: Lifestyle alteration is the main driver of healthseeking behaviour in FI. However, the majority do not seek treatment. Greater public and physician-awareness on FI and available treatment options is needed.

    PURPOSE: The escalating health-care spending for cancer management has caused cancer patients to struggle further as a result of financial burden. This systematic review was carried out to investigate the prevalence of perceived financial hardship and associated factors among cancer patients and their families.

    METHODS: A systematic search for studies concerning the perception of financial burden among cancer patients and their families was conducted. Several electronic resources such as Medline, Elsevier (Science Direct), Web of Science, Embase, PubMed, CINAHL and Scopus (SciVerse) were searched. Additionally, manual search through indices citation was also thoroughly utilized. The main outcome of interest was the prevalence of perceived financial hardship among cancer patients and their families. Studies reported only the cost of cancer treatment and qualitative studies were excluded. Our search was limited to articles that were published from 2003 to 2013.

    RESULT: Ten studies were included in this review and with a majority originating from high-income countries. The prevalence of the financial burden perception was reported between 14.8 and 78.8 %. The most frequent and significant risk factor reported associated with the perception of financial difficulty was the households with low income. Discontinuation of treatment and poverty were conversely the important consequences of financial burden in cancer patients and their families.

    CONCLUSION: Evidently, cancer is a long-term illness that requires a high financial cost, and a significant number of cancer patients and families struggle with financial difficulty. Identifying such groups with a high risk of facing financial difficulty is a crucial measure to ensure safety nets are readily available for these targeted population.

    OBJECTIVE: Screening for colorectal cancer using guaiac-based fecal occult blood tests (gFOBT) is well established in Western populations, but is hampered by poor patient compliance due to the imposed dietary restrictions. Fecal immunochemical tests (FIT) do not require dietary restriction, but are more expensive than gFOBT and therefore restrict its use in developing countries in Asia. However, Asian diets being low in meat content may not require diet restriction for gFOBT to achieve equivalent results. The objective of this study was to evaluate and compare the validity and suitability of gFOBT and FIT or a combination of the two in screening for colorectal neoplasias without prior dietary restriction in an Asian population.

    METHODS: Patients referred to the Endoscopic Unit for colonoscopy were recruited for the study. Stool samples were collected prior to bowel preparation, and tested for occult blood with both gFOBT and FIT. Dietary restriction was not imposed. To assess the validity of either tests or in combination to detect a neoplasm or cancer in the colon, their false positive rates, their sensitivity (true positive rate) and the specificity (true negative rate) were analyzed and compared.

    RESULTS: One hundred and three patients were analysed. The sensitivity for picking up any neoplasia was 53% for FIT, 40% for gFOBT and 23.3% for the combination. The sensitivities for picking up only carcinoma were 77.8% , 66.7% and 55.5%, respectively. The specificity for excluding any neoplasia was 91.7% for FIT, 74% for gFOBT and 94.5% for a combination, whereas for excluding only carcinomas they were 84%, 73.4% and 93.6%. Of the 69 with normal colonoscopic findings, FOBT was positive in 4.3%, 23.2 %and 2.9% for FIT, gFOBT, or combination of tests respectively.

    CONCLUSION: FIT is the recommended method if we are to dispense with dietary restriction in our patients because of its relatively low-false positivity and better sensitivity and specificity rates.

    BACKGROUND: Screening for colorectal cancer (CRC) improves outcomes and reduces its incidence. However, population-based screening in Malaysia continues to be a challenge, in view of cost and limited availability of colonoscopic skills and facilities. Conventional qualitative faecal occult blood tests help to prioritize those who require earlier colonoscopies, but cannot distinguish between benign and malignant causes. Recently, quantitative immunochemical faecal occult blood tests (qFOBT) have demonstrated some discriminatory ability in distinguishing benign and malignant causes. We aim to assess feasibility of qFOBT as a tool for stratification of colonoscopic priority in asymptomatic patients.
    METHODS: A health awareness exhibition was held in a major shopping complex in Kuala Lumpur on 6 and 7 Feb 2010. All asymptomatic individuals> 40 years, and those < 40 with family history of CRC, were invited to participate. Eligible participants were given a questionnaire and screened using a qFOBT. A faecal haemoglobin level of 100 - 199 ng/mL was considered moderately positive, while a level of 200 ng/mL or more was strongly positive. Participants with a strongly positive qFOBT result were scheduled for a colonoscopy within the month, while those who were moderately positive were scheduled within 3 months.
    RESULTS: A total of 125 (82%) participants returned the qFOBT kit, of which 70 (56%) were male. The median age was 54 years. Majority of the participants were Chinese (60%), followed by Malay (25%), Indian (12%) and others (3%). Twelve (10%) participants were tested positive and were advised to undergo colonoscopy but 9 (75%) declined colonoscopy and further investigations citing lack of time as the reason. Of the 3 participants (all in the moderately positive group) who underwent colonoscopy, 2 had a family history of CRC. Colonoscopic findings revealed haemorrhoids in one participant and two participants had histologically proven benign sigmoid colonic polyps.
    CONCLUSION: The use of qFOBT as a tool to screen and prioritize asymptomatic patients for early colonoscopy in CRC screening is logistically feasible. However, in order for it to be effective, measures to improve compliance to colonoscopy need to be taken.

    BACKGROUND: In Malaysia, the healthcare system consists of a government-run universal healthcare system and a co-existing private healthcare system. However, with high and ever rising healthcare spending on cancer management, cancer patients and their families are likely to become vulnerable to a healthcare-related financial burden. Moreover, they may have to reduce their working hours and lose income. To better understand this issue, this study aims to assess the financial burden of colorectal cancer patients and their families in the first year following diagnosis.

    METHODS: Data on patient costs were collected prospectively in the first year following diagnosis by using a self-administered questionnaire and telephone interviews at three time points for all four stages of colorectal cancer. The patient cost data consisted of direct out-of-pocket payments for medical-related expenses such as hospital stays, tests and treatment and for non-medical items such as travel and food associated with hospital visits. In addition, indirect cost data related to the loss of productivity of the patient and caregiver(s) was assessed. The patient's perceived level of financial difficulty and types of coping strategy were also explored.

    RESULT: The total 1-year patient cost (both direct and indirect) increased with the stage of colorectal cancer: RM 6544.5 (USD 2045.1) for stage I, RM 7790.1 (USD 2434.4) for stage II, RM 8799.1 (USD 2749.7) for stage III and RM 8638.2 (USD 2699.4) for stage IV. The majority of patients perceived paying for their healthcare as somewhat difficult. The most frequently used financial coping strategy was a combination of current income and savings.

    CONCLUSION: Despite the high subsidisation in public hospitals, the management of colorectal cancer imposes a substantial financial burden on patients and their families. Moreover, the majority of patients and their families perceive healthcare payments as difficult. Therefore, it is recommended that policy- and decision-makers should further consider some financial protection strategies and support for cancer treatment because cancer is a very costly and chronic disease.

    Tumor heterogeneity may give rise to differential responses to chemotherapy drugs. Therefore, unraveling tumor heterogeneity has an implication for biomarker discovery and cancer therapeutics. To test this phenomenon, we investigated the differential responses of three secondary colorectal cancer cell lines of different origins (HCT116, HT29, and SW620 cells) and four novel primary cell lines obtained from different colorectal cancer patients to 5-fluorouracil (5-FU) and oxaliplatin (L-OHP) and explored the differences in gene expression among the primary cell lines in response to exposure to cytotoxic drugs. Cells were exposed to different doses of 5-FU and L-OHP separately or in combinations of equitoxic drug or equimolar drug ratios (median effect of Chou-Talalay principle). Cell viability was assessed using MTT assay and the respective IC50values were determined. Changes in gene expression in primary cell lines after exposure to the same drug doses were compared using real-time PCR array. The sensitivities (IC50) of different cell lines, both secondary and primary, to 5-FU and L-OHP were significantly different, whether in monotherapy or combined treatment. Primary cell lines needed higher doses to reach IC50. There were variations in gene expression among the primary cell lines of different chemosensitivities to the challenge of the same combined dose of 5-FU and L-OHP. The results confirm the heterogeneous nature of colorectal cancer cells from different patient tumors. Studies using primary cancer cells established from patient's tumors rather than secondary cell lines will more closely reflect the actual character of the disease.

    AIM: The Sodergren score was developed to objectively measure the severity of haemorrhoidal symptoms. This study aimed to determine if there was a difference in the Sodergren score between patients who were offered surgery and patients who underwent successful rubber band ligation of internal haemorrhoidal disease and to assess its performance in guiding management.

    METHOD: This is a prospective, observational study. The preintervention Sodergren scores of subjects with internal haemorrhoidal disease were recorded and blinded to the surgeon in charge. Sodergren scores of subjects in the two arms were unblinded and compared at the end of the study.

    RESULTS: The results for 290 patients were available for final analysis. The median scores of those offered surgery and those who underwent successful rubber band ligation differed significantly [4 (interquartile range 3-10) vs 0 (interquartile range 0-4), P = 0.001]. In predicting treatment, the Sodergren score had an area under the receiver operating characteristic curve of 0.735 (95% CI 0.675-0.795).

    CONCLUSION: There is a significant difference in scores between patients who were offered surgery and patients with successful rubber band ligation. Our study suggests that the Sodergren score has an acceptable discrimination in predicting the need for surgery in internal haemorrhoidal disease. We propose that patients with a Sodergren score of 6 or more be considered for upfront surgery. This score could potentially be used to standardize outcomes of future haemorrhoid trials.

    Global surgery is a burgeoning area of global health. Surgeons can engage in one-or many-of the facets of global healthcare delivery: clinical care, capacity building, education, research, etc. Working in an increasingly global community, surgeons must be aware of the richness of cultural diversity at home and around the world such that they can provide culturally sensitive care. This chapter focuses on the most common way in which surgeons engage in global surgery: surgical short-term experiences in global health (STEGHs). Surgical STEGHs pose an intricate set of ethical dilemmas. As team leaders, surgeons must understand the community they intend to serve on these trips. Further, they should confirm that everyone who joins them is prepared to deliver care in a culturally sensitive and competent manner. Finally, surgeons must consider potential ethical dilemmas that may arise before, during, and after surgical STEGHs and have strategies to navigate them.

    The World Health Organization estimates that annually 150 million people experience severe (catastrophic) financial difficulties as a result of healthcare payments. Therefore, a systematic review was carried out to identify the determinants of household catastrophic health expenditure (CHE) in low-to high-income countries around the world. Both electronic and manual searches were conducted. The main outcome of interest was the determinants of CHE due to healthcare payments. Thirty eight studies met the inclusion criteria for review. The analysis revealed that household economic status, incidence of hospitalisation, presence of an elderly or disabled household member in the family, and presence of a family member with a chronic illness were the common significant factors associated with household CHE. The crucial finding of the current study is that socioeconomic inequality plays an important role in the incidence of CHE all over the world, where low-income households are at high risk of financial hardship from healthcare payments. This suggests that healthcare financing policies should be revised in order to narrow the gap in socioeconomic inequality and social safety nets should be implemented and strengthened for people who have a high need for health care.

    BACKGROUND: Colorectal cancer is the second most frequent cancer in Malaysia. Nevertheless, there is little information on treatment and outcomes nationally. We aimed to determine the demographic, clinical and treatment characteristics of colorectal cancer patients treated at the University Malaya Medical Centre (UMMC) as part of a larger project on survival and quality of life outcomes.

    MATERIALS AND METHODS: Medical records of 1,212 patients undergoing treatment in UMMC between January 2001 and December 2010 were reviewed. A retrospective-prospective cohort study design was used. Research tools included the National Cancer Patient Registration form. Statistical analysis included means, standard deviations (SD), proportions, chi square, t-test/ ANOVA. P-value significance was set at 0.05.

    RESULTS: The male: female ratio was 1.2:1. The mean age was 62.1 (SD12.4) years. Patients were predominantly Chinese (67%), then Malays (18%), Indians (13%) and others (2%). Malays were younger than Chinese and Indians (mean age 57 versus 62 versus 62 years, p<0.001). More females (56%) had colon cancers compared to males (44%) (p=0.022). Malays (57%) had more rectal cancer compared to Chinese (45%) and Indians (49%) (p=0.004). Dukes' stage data weres available in 67%, with Dukes' C and D accounting for 64%. Stage was not affected by age, gender, ethnicity or tumor site. Treatment modalities included surgery alone (40%), surgery and chemo/radiotherapy 32%, chemo and radiotherapy (8%) and others (20%).

    CONCLUSIONS: Significant ethnic differences in age and site distribution, if verified in population-based settings, would support implementation of preventive measures targeting those with the greatest need, at the right age.

    Recent advances in microRNAome have made microRNAs (miRNAs) a compelling novel class of biomarker in cancer biology. In the present study, the role of miR-23a in the carcinogenesis of colorectal cancer (CRC) was investigated. Cell viability, apoptosis, and caspase 3/7 activation analyses were conducted to determine the potentiality of apoptosis resistance function of miR-23a in CRC. Luciferase assay was performed to verify a putative target site of miR-23a in the 3'-UTR of apoptosis protease activating factor 1 (APAF1) mRNA. The expression levels of miR-23a and APAF1 in CRC cell lines (SW480 and SW620) and clinical samples were assessed using reverse transcription-quantitative real-time PCR (RT-qPCR) and Western blot. We found that the inhibition of miR-23a in SW480 and SW620 cell lines resulted in significant reduction of cell viability and promotion of cell apoptosis. Moreover, miR-23a up-regulation was coupled with APAF1 down-regulation in CRC tissue samples. Taken together, miR-23a was identified to regulate apoptosis in CRC. Our study highlights the potential application of miR-23a/APAF1 regulation axis in miRNA-based therapy and prognostication.

    There have been previous studies associating microorganisms to cancer and with our recent findings of Blastocytsis antigen having a higher in vitro proliferation of cancer cells strengthens the suspicion. Collecting faecal samples alone to associate this parasite with cancer may not be accurate due to the phenomenon of irregular shedding and the possible treatment administrated to the cancer patients. Hence, this become the basis to search for an alternate method of sample collection. Colonic washout is an almost complete washed up material from colon and rectum which includes various microorganisms such as Blastocystis and other lodged material within the villi. The detection of parasite in colonic washouts will give a better reflection on the association between Blastocystis and CRC.

    Early diagnosis of rectal cancer is important for prompt treatment and better outcome. Little data exists for comparison or to set standards. The primary objective of this study is to identify factors resulting in delays in treatment of rectal cancer, the correlation between the disease stage and diagnosis waiting time, treatment waiting time and duration of symptoms. A five year retrospective audit was undertaken in University of Malaya Medical Centre (UMMC). There were 137 patients recruited and the median time to diagnosis was nine days after the first UMMC Surgical Unit consultation with a mean of 18.7 days. Some 11% had to wait more than four weeks for diagnosis. The median time from confirmation of diagnosis to surgery was 11 days with a mean of 18.6 days. Sixty-two percent of patients were operated upon within two weeks of diagnosis and more than 88% by four weeks. However, 10% of them had delayed surgery done four weeks after diagnosis. Long colonoscopy waiting time was the main cause for delay in diagnosis while delay in staging CTs were the main reason for treatment delays.
