Introduction: Colorectal cancer (CRC) is one of the leading cancers in Malaysia where new
cases are increasing every year. The aim of this study was to test the reliability and validity of a
newly developed questionnaire on knowledge, attitude and dietary practices (KAP) related to CRC
for the Malay population.
Methods: The respondents were conveniently selected among visitors attending an
outpatient clinic in a tertiary hospital. We excluded those with any cancers, chronic diseases and
those that were illiterate. The exploratory factor and reliability analyses were conducted.
Results: A total of 108 respondents were recruited of which 67.7% were males and the
mean age was 54.59 years (standard deviation 8.93). The Kaiser-Meyer-Olkin (KMO) measure of
sampling adequacy values for KAP were 0.64, 0.66 and 0.67, respectively (P < 0.001). The 17 items
of knowledge formed five domains with loading factors ranging from 0.54–0.89. The six items of
attitude formed two domains with loading factors ranging from 0.64–0.80 and the 15 practices
had four domains with loading factors ranging from 0.52–0.83. The total variances explained for
each KAP were 61.02%, 56.41% and 53.12%, respectively. The internal consistency Cronbach alpha
values on KAP were 0.61, 0.60 and 0.70, respectively.
Conclusion: The final questionnaire is suitable for measuring KAP related to CRC among
the Malay population.

Purpose:
Oncological outcomes following rectal cancer surgery have improved significantly over recent decades with lower recurrences and longer overall survival. However, many of the patients experienced low anterior resection syndrome (LARS). This study identified the prevalence and risk factors associated with the development of LARS.
Methods:
This cross-sectional study involved patients who were diagnosed with rectal cancer and had undergone sphincter-preserving low anterior resection from January 2011 to December 2020. Upon clinic follow-up, patients were asked to complete an interviewed based questionnaire (LARS score) designed to assess bowel dysfunction after rectal cancer surgery.
Results:
Out of 76 patients, 25 patients (32.9%) had major LARS, 10 patients (13.2%) had minor LARS, and 41 patients (53.9%) had no LARS. The height of tumor from anal verge showed an association with the development of major LARS (P=0.039). Those patients with less than 8 cm tumor from anal verge had an increased risk of LARS by 3 times compared to those with 8 cm and above (adjusted odds ratio, 3.11; 95% confidence interval, 1.06–9.13).
Conclusion
Results from our study show that low tumor height was a significant risk factor that has a negative impact on bowel function after surgery. The high prevalence of LARS emphasizes the need for study regarding risk factors and the importance of understanding the pathophysiology of LARS, in order for us to improve patient bowel function and quality of life after rectal cancer surgery.

Purpose:
Guaiac fecal occult blood test (gFOBT) has been the standard for colorectal screening but it has low sensitivity and specificity. This study evaluated the use of fecal tumor M2-pyruvate kinase (M2-PK) for detection of colorectal cancer and to compare with the current surveillance tool; gFOBT in symptomatic adult subjects underwent colonoscopy.
Methods:
Stool samples were collected prospectively from symptomatic adults who had elective colonoscopy from September 2014 to January 2016 and were analyzed with the ScheBo M2-PK Quick test and laboratory detection of fecal hemoglobin.
Results:
The results were correlated to the colonoscopy findings and/or histopathology report. Eighty-five subjects (age of 56.8 ± 15.3 years [mean ± standard deviation]) were recruited with a total of 17 colorectal cancer (20.0%) and 10 colorectal adenoma patients (11.8%). The sensitivity of M2-PK test in colorectal cancer detection was higher than gFOBT (100% vs. 64.7%). M2-PK test had a lower specificity when compared to gFOBT (72.5% vs. 88.2%) in colorectal cancer detection. The positive and negative predictive values were 47.2% and 100% for M2-PK test and 57.9% and 90.9% for gFOBT.
Conclusion
Fecal M2-PK Quick test has a high sensitivity for detection of colorectal cancer when compared to gFOBT, making it the potential choice for colorectal tumor screening biomarker in the future.

Juvenile polyps (JPs) are the most common polyps in pediatric patients. We present the case of an 18-year-old male patient with a giant solitary JP resembling solitary rectal ulcer syndrome (SRUS). The presenting history was rectal bleeding and symptoms of obstructed defecation syndrome. Colonoscopy revealed a polypoidal mass at the anorectal junction, with biopsy-confirmed SRUS. The symptoms worsened, and a protruding mass from the anus caused fecal incontinence. Pelvic magnetic resonance imaging showed a huge pedunculated mass occupying the low rectum with local compression of the urinary bladder. Transanal excision of the anal tumor was performed due to bleeding. A histopathological examination showed a JP with high-grade dysplasia. A histological examination to differentiate JPs and SRUS could be challenging based on a superficial forceps biopsy. Therefore, an excision biopsy is usually warranted with the understanding that adenomatous or malignant transformation is found in 5.6% to 12% of all JPs.

Purpose:
Laparoscopic appendicectomy (LA) has several advantages over conventional open appendicectomy (OA). However, about 5% to 10% of LA patients still need to be converted to open surgery. Identifying risk factors that contribute to conversion to OA allows for early identification of patients who may benefit from primary OA. This study aimed to determine the conversion rate of LA to OA and to identify its associated risk factors among patients with acute or perforated appendicitis.
Methods:
A retrospective review of medical records was performed among patients with acute or perforated appendicitis who underwent LA between December 2015 and January 2017. With the use of multivariable logistic regression analyses, the predictors of conversion from laparoscopic to OA were investigated.
Results:
Out of 120 patients, 33 cases were converted to OA which gives a conversion rate of 27.5%. Among 33 patients who were converted to OA, 27 patients (81.8%) had perforated appendix, while in the LA group, perforated appendix cases consisted of 34.5% (P<0.001). Histopathology of the appendix was the predictor of conversion from LA to OA (adjusted odds ratio, 8.82; 95% confidence interval, 3.13–24.91; P<0.001).
Conclusion
The result from our study shows that the overall conversion rate for the study period was high. Patients with perforated appendicitis had a higher risk of conversion to OA. Therefore, preoperative diagnosis of perforated appendicitis may be paramount in predicting conversion to OA.

PURPOSE:
Patients with secondary hyperparathyroidism are at high risk for developing postoperative hypocalcemia. However, there are limited data regarding predictors of postoperative hypocalcemia in renal failure patient with secondary hyperparathyroidism. This study aimed to determine the clinical presentations of renal hyperparathyroidism and the predictors of early postoperative hypocalcemia after total parathyroidectomy.
METHODS:
Data of patients with renal hyperparathyroidism who underwent total parathyroidectomy between January 2007 to December 2014 were reviewed retrospectively. Patients were divided into 2 cohort groups according to their serum calcium levels within 24 hours of parathyroidectomy: the hypocalcemia group (calcium levels of 2 mmol/L or less), and the normocalcemia group (calcium levels more than 2 mmol/L). With the use of multivariable logistic regression analyses, the predictors of early postoperative hypocalcemia after total parathyroidectomy in patients with renal hyperparathyroidism were investigated.
RESULTS:
Among 68 patients, 56 patients (82.4%) were symptomatic preoperatively. Fifty patients (73.5%) presented with bone pain and 14 patients (20.6%) had muscle weakness. Early postoperative hypocalcemia occurred in 25 patients (36.8%). Preoperative alkaline phosphatase level was the predictor of early postoperative hypocalcemia (adjusted odds ratio, 1.004; 95% confidence interval, 1.001–1.006; P = 0.002).
CONCLUSION
Results from our study show that most of the patients with renal hyperparathyroidism were symptomatic preoperatively and the most common clinical presentations were bone pain and muscle weakness. The significant predictor of early postoperative hypocalcemia after total parathyroidectomy was the preoperative alkaline phosphatase levels.

Biliary ascariasis is a rare disease in a non-endemic area. However, it is one of the possible etiological factors for retarded growth as well as malnutrition in children. It may cause intestinal obstruction, appendicitis, biliary obstruction, liver abscess, hepatolithiasis, and pancreatitis in adults. Herein, we report a patient with ascending cholangitis secondary to biliary ascariasis who was successfully managed with Endoscopic Retrograde Cholangio Pancreaticography.

Background & Objectives: The National Institute of Health Stroke Scale (NIHSS) provides a valid
and quick assessment of stroke severity in hyperacute stroke management. Stroke patients who are
eligible for reperfusion therapy require prompt assessment. There is no validated Bahasa Malaysia
(BM) version of the NIHSS that allows easier assessment by BM-speaking health professionals.
This study aimed to translate and validate a BM version of the NIHSS. Methods: The English NIHSS
was translated to BM, then back translated to ensure linguistic accuracy. We also adapted the language
assessment of the NIHSS to be more culturally appropriate. Training and certification videos were
downloaded from the NIH website and dubbed into BM. We determined intra-class correlation and
unweighted kappa as the best measure of reliability. Median scores were used in the analysis for
language items. Results: One hundred and one raters participated in the test-retest reliability study.
Agreement between the original NIHSS and our translated version of the BM-NIHSS was good (ICC
= 0.738, 95% CI: 0.611 to 0.823). Fair to moderate agreement was found on item-by-item analysis
(unweighted κ=0.20-0.50) despite high observed agreement. Fifty patients participated in the language
assessment arm. Scores were better in BM for reading, naming objects and repetition (Mdn = 100, p
< 0.001). There was no difference in the median scores for the description component.
Conclusions: The BM-NIHSS is a valid translation of the NIHSS, and may be used in clinical practice
by BM-speaking healthcare professionals.

Background & Objectives: The reported incidence of post-stroke delirium varies substantially in current
medical literature. The impact of delirium on mortality and morbidity is significant and there is need
for sustained research on the topic. We aimed to determine the incidence, risk factors and outcome of
delirium in acute ischaemic stroke. Methods: We conducted a cross-sectional observational study on
consecutive patients with ischaemic stroke. The Confusion Assessment Method was used to diagnose
delirium within seven days of stroke onset. Results: Two hundred and eighty patients were recruited
(mean age 63.6 years) and 36 (12.9%) developed delirium. After adjustments for covariates, age >65
years (odds ratio, OR 5.2; 95% confidence interval 1.6-17.5); pre-existing dementia (6.5; 1.1-38.2);
TACI (7.2; 1.5-35); and a National Institute of Health Stroke Scale of ≥10 (6.8; 1.7-26.4), were
independently associated with a risk of developing delirium. Lacunar infarcts were not associated with
delirium (0.07; 0.03-0.16). The majority of patients with delirium were cared for in a dedicated stroke
unit but this proportion was not significant compared to those without delirium (69.4% vs 58.2%,
p=0.20). Delirious patients had significantly higher in-patient mortality (8.3% vs 0%, p=0.002) and
longer length of hospital stay (6.94 vs 3.98 days, p< 0.001).
Conclusions: One in 8 patients with ischaemic stroke in our centre developed delirium. Older age,
pre-existing dementia and severe stroke were independent predictors of delirium. Patients with lacunar
infarcts did not develop delirium as often as those with other stroke types. Delirium significantly
increased in-patient mortality and length of hospital stay.
