    BACKGROUND: To date, several medication adherence apps have been developed. However, the existing apps have been developed without involving relevant stakeholders and were not subjected to mobile health app guidelines. In addition, the usability and utility of these apps have not been tested with end users.

    OBJECTIVE: This study aimed to describe the usability and utility testing of a newly developed medication adherence app-Med Assist-among ambulatory care patients in Malaysia.

    METHODS: The Med Assist app was developed based on the Theory of Planned Behavior and the Nielson usability model. Beta testing was conducted from March to May 2016 at a primary care clinic in Kuala Lumpur. Ambulatory care patients who scored ≥40% on the electronic health literacy scale, were aged ≥21 years, and were taking two or more long-term medications were recruited. Two rounds of in-depth interviews were conducted with each participant. The first interview, which was conducted upon participant recruitment, was to assess the usability of Med Assist. Participants were asked to download Med Assist on their phone and perform two tasks (register themselves on Med Assist and enter at least one medication). Participants were encouraged to "concurrently think aloud" when using Med Assist, while nonverbal cues were observed and recorded. The participants were then invited for a second interview (conducted ≥7 days after the first interview) to assess the utility of Med Assist after using the app for 1 week. This was done using "retrospective probing" based on a topic guide developed for utilities that could improve medication adherence.

    RESULTS: Usability and utility testing was performed for the Med Assist app (version P4). A total of 13 participants were recruited (6 men, 7 women) for beta testing. Three themes emerged from the usability testing, while three themes emerged from the utility testing. From the usability testing, participants found Med Assist easy to use and user friendly, as they were able to complete the tasks given to them. However, the details required when adding a new medication were found to be confusing despite displaying information in a hierarchical order. Participants who were caregivers as well as patients found the multiple-user support and pill buddy utility useful. This suggests that Med Assist may improve the medication adherence of patients on multiple long-term medications.

    CONCLUSIONS: The usability and utility testing of Med Assist with end users made the app more patient centered in ambulatory care. From the usability testing, the overall design and layout of Med Assist were simple and user friendly enough for participants to navigate through the app and add a new medication. From the participants' perspectives, Med Assist was a useful and reliable tool with the potential to improve medication adherence. In addition, utilities such as multiple user support and a medication refill reminder encouraged improved medication management.

    BACKGROUND: This study aims to predict risk factors for urological anomalies in children with anorectal malformations (ARM) and describes the clinical features of patients who have developed chronic kidney disease.

    METHODS: We retrospectively reviewed infants with ARM who received surgery and were followed at the Sabah Women and Children's Hospital, Malaysia, from 1986 to 2010.

    RESULTS: One hundred and twenty-two children with anorectal malformations were studied, after excluding 24 children with incomplete data. Three factors were significant as predictors of the presence of a urological anomaly: high ARM lesion (OR 3.12, 95%CI 1.1-8.9), the presence of genital abnormality (OR 2.95, 95%CI 1.10-7.91) and cloacal anomaly in girls (OR 8.27, 95% CI 1.91-35.6). The most common anomalies were vesicoureteric reflux, single kidney and neurogenic bladder. Chronic kidney disease (CKD) was noted in 5.7%, in children who had recurrent urinary tract infections, neurogenic bladder or complex renal tract pathology; end-stage renal failure was seen in only 0.8% of children with ARM.

    CONCLUSION: Urological anomalies were seen in 23% of patients, but the overall incidence of CKD and end-stage renal disease is low. Early identification of infants with ARM at risk of renal failure may be important for renal survival.

    INTRODUCTION: Melioidosis is endemic to the tropical regions, in particular Thailand and Northern Australia. Any organ can be affected by melioidosis. Involvement of the urogenital system is common in Northern Australia, but is less common in other regions. This study assesses the characteristics of melioidosis affecting the urogenital system treated in a tertiary referral centre in Brunei Darussalam.

    MATERIAL AND METHODS: All patients treated for melioidosis of the urogenital system were identified and retrospectively reviewed.

    RESULTS: There were 9 patients with 11 episodes of urogenital infections treated over 13 years. The median age at diagnosis was 38 years old (range 29 - 63) with men predominantly affected. The major risk factor was underlying diabetes mellitus (n=9), including three patients diagnosed at the time of diagnosis of melioidosis. The median glycosylated haemoglobin (HbA1c) was 12.8% (range 6.4 to 16.6%). One patient's risk factor was only moderate alcohol consumption. Common symptoms included; fever, lethargy, rigor and anorexia. Dysuria was reported by two patients. The median duration of symptoms before presentation was 7 days (range 2 to 21 days) and the median number of sites involved were 3 (range of 2 to 6). Urogenital involvement included prostate (n=6), kidney (n=8), seminal vesicles (n=1) and testis (n=1). Radiological imaging showed that large prostate abscesses (>4.5cm) were common, and in some patients, the kidney abscess had the 'honeycomb' previously described as typical for melioidosis liver abscess. All patients were successfully treated for melioidosis and at a median follow up of 34 months (range 1 - 97), there was one death from complications of diabetes mellitus.

    CONCLUSION: Urogenital melioidosis only accounted for a small proportion of all melioidosis involvement, with prostate and kidney most commonly affected. Concomitant involvement of other sites were common. The major risk factor was poorly controlled diabetes mellitus.

    216 patients were found to have had surgery for urinary calculi In a retrospective analysis of surgical records of the two general hospitals in Kelantan over a two year period. Excluding 11 patients from Terengganu and 2 patients resident in Kelantan for less than 1 year, this amounts to an annual incidence for calculus surgery of 10 per 100,000 residents per year. Lower urinary tract (LT) calculi (143) were more common than upper urinary tract (UT) calculi (71). There was an overwhelming majority of males among patients operated on for LT calculi (ratio of males:females = 1.2:1). The mean age of patients with UT calculi was 44 years, while that of LT calculi was 51 years.

    The clinical features and aetiology of 100 consecutive symptomatic heterosexual male patients with urethritis were studied from March 1994 to August 1994 in the Genito-Urinary Medicine (GUM) Clinic, Kuala Lumpur Hospital. Gonococcal urethritis (GU) was found to be more common (53%) than non-gonococcal urethritis(47%). All patients with GU confirmed microbiologically had clinically evident urethral discharge. Almost half (41%) of the patients with GU developed post-gonococcal urethritis (PGU). The most common organism isolated in PGU was Ureaplasma urealyticum (37%) whilst only 4% had both Chlamydia trachomatis and Ureaplasma urealyticum. Of the 47% of patients with non-gonococcal urethritis (NGU), 50% had no microorganism isolated, 32% had Ureaplasma urealyticum, 7% Chlamydia trachomatis and 11% both Chlamydia trachomatis and Ureaplasma urealyticum.

    Between November 1994 to May 1996, there was a total of eight ureteric injuries out of 2495 major gynaecologic operations and one ureteric injury out of 4146 caesarean sections at the Kandang Kerbau Hospital, giving the incidence to be 0.3% and 0.02% respectively. Antecedent operations were four abdominal hysterectomies, two Werthiem's hysterectomies, one laparoscopic-assisted vaginal hysterectomy and one caesarean section. All operations were performed by qualified specialists. Three patients had previous abdominal operations and five patients had procedures complicated by dense adhesions. Only one injury was detected intraoperatively and the rest presented with uretero-vaginal fistula. One presented with immediate postoperative anuria. The average time interval for diagnosis ranged between one day and twenty-three days (average 10.7 days). The commonest damage was transection of the ureter. Double J stents were used in all repairs with two cases requiring reimplantation with psoas hitch, and two cases of ureteroneocystostomies and one case of primary reanastomosis. There were no mortality in our series.

    OBJECTIVE: To investigate the association between postoperative upper instrumented vertebrae (UIV) tilt angle with postoperative medial shoulder and neck imbalance.

    SUMMARY OF BACKGROUND DATA: Studies had found that current recommendations for UIV selection were not predictive of good postoperative shoulder balance.

    METHODS: A total of 98 patients with adolescent idiopathic scoliosis with Lenke 1/2 curves who underwent posterior spinal fusion between 2013 and 2014 with minimum follow-up of 2 years were recruited. Radiological parameters: UIV tilt angle, T1 tilt, cervical axis, and clavicle angle were measured preoperatively, postoperatively, and at final follow-up.

    RESULTS: Mean age was 16.2 ± 6.2 years. Mean follow-up was 37.9 ± 6.5 months. There were 73.5% Lenke 1 and 26.5% Lenke 2 curves. Significant factors affecting postoperative T1 Tilt were postoperative UIV tilt angle, preoperative T1 tilt, and preoperative UIV tilt angle. Postoperative UIV tilt angle and preoperative cervical axis were significant factors affecting cervical axis at final follow-up. UIV level was not significant independent factor that affected postoperative T1 tilt and cervical axis. There was strong correlation between postoperative UIV tilt angle and T1 tilt for the whole cohort (P

    INTRODUCTION: Tuberculosis (TB), a curable and preventable infectious disease, becomes difficult to treat if resistance against most effective and tolerable first line anti-TB drugs is developed. The objective of the present study was to evaluate the treatment outcomes and predictors of poor outcomes among drug-resistant tuberculosis (DR-TB) patients treated at a programmatic management unit of drug resistant tuberculosis (PMDT) unit, Punjab, Pakistan.

    METHODS: This prospective observational study was conducted at a a PMDT unit in Multan, Punjab, Pakistan. A total of 271 eligible culture positive DR-TB patients enrolled for treatment at the study site between January 2016 and May 2017 were followed till their treatment outcomes were recorded. World Health Organization's (WHO) defined criteria was used for categorizing treatment outcomes. The outcomes of cured and treatment completed were collectively placed as successful outcomes, while death, lost to follow-up (LTFU) and treatment failure were grouped as unsuccessful outcomes. Multivariable binary logistic regression analysis was employed for getting predictors of unsuccessful treatment outcomes. A p-value <0.05 was considered statistically significant.

    RESULTS: Of the 271 DR-TB patients analysed, nearly half (51.3%) were males. The patient's (Mean ± SD) age was 36.75 ± 15.69 years. A total of 69% patients achieved successful outcomes with 185 (68.2%) patients being cured and 2 (0.7%) completed therapy. Of the remaining 84 patients with unsuccessful outcomes, 48 (17.7%) died, 2 (0.7%) were declared treatment failure, 34 (12.5%) were loss to follow up. After adjusting for confounders, patients' age > 50 years (OR 2.149 (1.005-4.592) with p-value 0.048 and baseline lung cavitation (OR 7.798 (3.82-15.919) with p-value <0.001 were significantly associated with unsuccessful treatment outcomes.

    CONCLUSIONS: The treatment success rate (69%) in the current study participants was below the target set by WHO (>75%). Paying special attention and timely intervention in patients with high risk of unsuccessful treatment outcomes may help in improving treatment outcomes at the study site.

    OBJECTIVES: To study the rate of unplanned PICU readmission, determine the risk factors and its impact on mortality.

    DESIGN: A single-center retrospective cross-sectional study.

    SETTING: Tertiary referral PICU in Johor, Malaysia.

    PATIENTS: All children admitted to the PICU over 8 years were included. Patients readmitted into PICU after the first PICU discharge during the hospitalization period were categorized into "early" (within 48 hr) and "late" (after 48 hr), and factors linked to the readmissions were identified. The mortality rate was determined and compared between no, early, and late readmission.

    INTERVENTIONS: None.

    MEASUREMENTS AND MAIN RESULTS: There were 2,834 patients in the study with 70 early and 113 late readmissions. Therefore, the rate of early and late PICU readmission was 2.5% (95% CI, 1.9-3.0%) and 3.9% (95% CI, 3.2-4.7%), respectively. The median length of stay of the second PICU admission for early and late readmissions was 2.7 days (interquartile range, 1.1-7.0 d) and 3.2 days (interquartile range, 1.2-7.5 d), respectively. The majority of early and late readmissions had a similar diagnosis with their first PICU admission. Multivariable multinomial logistic regression revealed a Pediatric Index Mortality 2 score of greater than or equal to 15, chronic cardiovascular condition, and oxygen supplement upon discharge as independent risk factors for early PICU readmission. Meanwhile, an infant of less than 1 year old, having cardiovascular, other congenital and genetic chronic conditions and being discharged between 8 AM and 5 PM was an independent risk factor for late readmission. There was no significant difference in the mortality rate of early (12.9%), late (13.3%), and no readmission (10.7%).

    CONCLUSIONS: Despite the lack of resources and expertise in lower- and middle-income countries, the rate and factors for PICU readmission are similar to those in high-income countries. However, PICU readmission has no statistically significant association with mortality.

    OBJECTIVES: Unexplained subfertility (UEI) describes a couple whose standard subfertility workout consider acceptable but unable to conceived.

    METHODS: This retrospective study was conducted in the Advanced Reproductive Centre, UKM Hospital, Kuala Lumpur, from January 2016 to December 2019. The data of 268 UEI couples were obtained from the clinical database. Women aged 21-45 years old was included and further divided into four groups according to the female partner's age and subfertility duration: group A (age <35 years and subfertility <2 years), group B (age <35 years and subfertility >2 years), group C (age >35 years and subfertility <2 years), and group D (age >35 years and subfertility <2 years). All statistical analyses were performed using SPSS 22.0 for Windows.

    RESULTS: A total of 255 cases were included in this study. The mean age of the women was 32.9 ± 4.04 years, and the mean subfertility duration was 5.04 ± 2.9 years. A total of 51 (20 %) cases underwent timed sexual intercourse, 147 (57.6 %) cases had intrauterine insemination (IUI), whereas 57 (22.4 %) cases opted for in vitro fertilization (IVF). A total of 204 cases underwent active management (IUI/IVF), which showed a significant difference (p<0.05). Out of eight clinical pregnancies, half of them were from group B.

    CONCLUSIONS: Active management in younger women with a shorter subfertility duration revealed a better pregnancy outcome. Otherwise, individualized treatment should be considered in selecting a suitable treatment plan.

    There are well-established guidelines regarding the use of Angiotensin converting enzyme inhibitors (ACEI) in the management of heart failure (HF). In-spite of that, many studies has documented underutilization of ACEI. Thus, this retrospective observational study aimed to evaluate the utilization of ACEI, to identify the pattern of ACEI use and the factors that might contribute to underutilization of ACEI. The target population was hospitalized HF patients in University Malaya Medical Centre (UMMC). Of 321 hospitalized HF patients, only 57% of them were treated with ACEI. 51.2% of the patients treated with ACEI received low dose (< or = 25% from target dose) at discharge. Factors that have significant association with the underutilization of ACEI included serum potassium and creatinine, chronic renal failure and other concurrent medications used (frusemide, aspirin, potassium chloride, calcium channel blockers and angiotensin receptor blockers). The findings indicated that the utilization of ACEI in the management of HF in UMMC is considerably low.

    OBJECTIVE: Special Study Module (SSM) is a mandatory research module implemented in Universiti Kebangsaan Malaysia (UKM). The objective of this paper is to provide a brief overview on the student research activities and to find out the outcome measures in terms of publication.
    METHODS: It was a retrospective study done on SSM research projects at UKM. The SSM research is conducted from beginning of year-4 until 1(st) seven weeks of year-5. In year-4, students are assigned to a faculty-supervisor in small groups and spend every Thursday afternoon to plan and carry the research. Whole first seven weeks of year-5, students are placed with their supervisor continuously to collect data, do analysis, write report and present in the scientific conference. Outcomes of 5-years SSM research-projects starting from 2008/2009 to 2012/2013 academic session were analyzed.
    RESULTS: Total 257 projects were completed and presented in annual scientific meetings from which 57 (22.2%) articles were published in peer reviewed journals.
    CONCLUSION: Mandatory undergraduate student research project brings an opportunity to develop students' capacity building from conception to final report writing and thereby narrowing the gap between education and practice. Medical schools should implement research module to bring changes in research and publication culture of undergraduate medical education.

    OBJECTIVE: The aim of this study was to evaluate a novel pericardiocentesis technique using an in-plane parasternal medial-to-lateral approach with the use of a high-frequency probe in patients with cardiac tamponade.

    BACKGROUND: Echocardiography is pivotal in the diagnosis of pericardial effusion and tamponade physiology. Ultrasound guidance for pericardiocentesis is currently considered the standard of care. Several approaches have been described recently, which differ mainly on the site of puncture (subxiphoid, apical, or parasternal). Although they share the use of low-frequency probes, there is absence of complete control of needle trajectory and real-time needle visualization. An in-plane and real-time technique has only been described anecdotally.

    METHODS AND RESULTS: A retrospective analysis of 11 patients (63% men, mean age: 37.7±21.2 years) presenting with cardiac tamponade admitted to the tertiary-care emergency department and treated with parasternal medial-to-lateral in-plane pericardiocentesis was carried out. The underlying causes of cardiac tamponade were different among the population. All the pericardiocentesis were successfully performed in the emergency department, without complications, relieving the hemodynamic instability. The mean time taken to perform the eight-step procedure was 309±76.4 s, with no procedure-related complications.

    CONCLUSION: The parasternal medial-to-lateral in-plane pericardiocentesis is a new technique theoretically free of complications and it enables real-time monitoring of needle trajectory. For the first time, a pericardiocentesis approach with a medial-to-lateral needle trajectory and real-time, in-plane, needle visualization was performed in a tamponade patient population.

    Purpose: To evaluate the usefulness of ultrasound guidance in percutaneous needle biopsy for musculoskeletal tumours.
    Methods: Forty-five consecutive patients underwent ultrasound-guided needle biopsy. An additional group of 50 patients who underwent needle biopsy without ultrasound guidance was retrospectively selected as historical control. The sample was considered adequate when a diagnosis can be made, and diagnostic when the diagnosis is similar to the final report based on the excised tumour.
    Results: Adequacy of the biopsy samples was 84% in ultrasound-guided group as compared 76% in the group with no ultrasound guidance. Diagnostic accuracy was 64% in the ultrasound-guided group and 52% in the group without ultrasound guidance. Both of these differences were not statistically significant.
    Conclusions: Ultrasound guidance did not provide a significant advantage in the biopsy of musculoskeletal tumours. Diagnostic accuracy seems to improve with the use of larger 14 gauge biopsy needle but further evaluation is necessary.

    Ultrasound examinations were done to evaluate clinically palpable abdominal masses in 125 children. The examinations were normal in 21 patients. In 15 patients, the clinically palpable masses were actually anterior abdominal wall abscesses or hematomas. Final diagnosis was available in 87 of 89 patients with intraabdominal masses detected on ultrasound. The majority (71%) were retroperitoneal masses where two-thirds were of renal origin. Ultrasound diagnosis was correct in 68 patients (78%). All cases of hydronephrosis were correctly diagnosed based on characteristic ultrasound appearances. Correct diagnoses of all cases of adrenal hematoma, psoas abscess, liver hematoma, liver abscess and one case of liver metastases were achieved with correlation of relevant clinical information.

    A retrospective analysis of 49 patients with 55 liver abscesses evaluated by diagnostic ultrasonography was made. The sonographic appearances were varied and non-specific. 96% of the abscesses were in the right lobe of the liver. Sonographic features which were frequently observed include (a) predominantly hypoechoic internal echotexture (64%) (b) distal sonic enhancement (98%) (c) well-defined margin with an abrupt transition between normal liver parenchyma and lesion (96%) and (d) absence of wall echoes (89%). A combination of these features has considerable diagnostic value. Distal sonic enhancement is of particular diagnostic importance. In equivocal cases the diagnosis can be quickly determined by percutaneous needle aspiration under ultrasound guidance.

    Selective cervical nerve root injection using a mixture of corticosteroid and lignocaine is a treatment option for managing cervical radiculopathic pain. The procedure is usually performed under image guided fluoroscopy or Computerized Tomograhy. Ultrasound-guided cervical nerve root block does not expose the patients and personnel to radiation. During injection, the fluid is mostly visualized in a real-time fashion. This retrospective study reviewed the effectiveness of ultrasound in guiding cervical peri-radicular injection for pain relief in patients with recalcitrant cervical radiculopathy. There were no complications reported in this series.

    Better methods are required to identify patients with asymptomatic carotid stenosis (ACS) at risk of future stroke. Two potential markers of high risk are echolucent plaque morphology on carotid ultrasound and embolic signals (ES) in the ipsilateral middle cerebral artery on transcranial Doppler ultrasound (TCD). We explored the predictive value of a score based on these 2 measures in the prospective, observational, international multicenter Asymptomatic Carotid Emboli Study.

    AIM: Inflammatory bowel disease appears to be uncommon among Asians. This study was conducted to determine the prevalence of ulcerative colitis (UC) in Malaysian patients and to establish the spectrum of the disease seen in Malaysian patients. Three major Asian races: Malay, Chinese, and Indian co-exist in Malaysia and we sought to determine if there were any racial differences in the prevalence and presentation of disease. Racial differences for several other gastrointestinal diseases have previously been observed and found to be extremely interesting.

    METHODS: Data were obtained retrospectively from a review of the medical records of in- and out-patients with a diagnosis of UC at the University Hospital, Kuala Lumpur between 1985 and 1998.

    RESULTS: There were 45 confirmed cases of UC of which 3 were foreigners, who were excluded from analysis. Thirty new cases of UC were diagnosed during the study period. Their mean age at presentation was 33.0+/-10.0 years. The highest prevalence of UC was 17.9/100 000 hospital admissions in the Indians, followed by 11.2/100 000 hospital admissions in the Chinese. The lowest prevalence was 3.7/100 000 hospital admissions in the Malays. The prevalence of UC was significantly higher in the Indians and the Chinese when compared with the Malays with an OR of 4.89 (CI = 2.02-12.24; chi2 = 15.45, P<0.001) and 3.06 (CI = 1.24-7.78; chi2 = 6.30; P = 0.012) respectively. The extent of colonic disease was similar in the Malay and Indian patients. In contrast, distal or left-sided colitis predominated in the Chinese with an OR of 8.17 (95%CI = 1.31-64.87; chi2 = 5.53, P = 0.02). Extraintestinal manifestations were uncommon (11.9%).

    CONCLUSION: UC is an uncommon disease in Malaysia, but racial differences exist. The Indians had the highest prevalence of UC with the Chinese demonstrating the least extensive disease.
