Fulltext An analysis of glaucoma patients seen at the General Hospital Kuala Lumpur over a five year period: 1986 to 1990

Selvarajah S

Med J Malaysia, 1998 Mar;53(1):42-5.
PMID: 10968136

The records of all the glaucoma patients seen at the General Hospital Kuala Lumpur over a five year period were analysed. The racial, age and sex distribution of patients with primary open angle glaucoma and primary angle closure glaucoma was determined. The causes of secondary glaucoma were analysed. As no previous records of glaucoma statistics are available in Malaysia, it is hoped that these findings will form an initial mosaic to build on in the future.

Hip fracture incidence in Malaysia 1981-1989

Lee CM, Sidhu JS, Pan KL

Acta Orthop Scand, 1993 Apr;64(2):178-80.
PMID: 8498181 DOI: 10.3109/17453679308994565

The age-corrected incidence of hip fracture in the city of Kuala Lumpur and the surrounding districts has increased from 1981 to 0.7 per 1,000 population in 1989. Women dominated by a factor of 1.3. The mean age was 73 (50-103) years. The increased rate observed was attributed solely to trochanteric fractures among those 70 years and above. There were differences in the various parameters among the different races. The fracture incidence and woman/man ratio were substantially lower than has been reported from developed countries.

Fulltext Results of 50 consecutive aneurysmectomies for abdominal aortic aneurysms at a private specialist centre

Leong YP, Sappany A

Med J Malaysia, 1995 Dec;50(4):330-3.
PMID: 8668052

The management of abdominal aortic aneurysms (AAA) at a private medical centre was reviewed. The criteria for surgery were AAA more than or equal to five centimeters in diameter, symptomatic AAA even if less than five centimeters and ruptured AAA. A total of 67 patients were seen between October 1991 to September 1994. The age range was 48 to 94 years, mean = 69.8. There were 58 males to nine females. Twelve patients presented with ruptured AAA. There were three suprarenal AAA and three mycotic AAA. Aneurysmectomies were performed on 50 patients. This include all patients with ruptured AAA. There was no mortality in the elective cases. One patient with ruptured AAA died, ie. an operative mortality of eight per cent. It was concluded that a very low operative mortality can be achieved in this group of high risk patients. Our results were comparable to those reported by other centres in the developed countries. Important factors contributing to these results include a team approach in a unit interested in this disease, careful pre-operative preparation and a rigid post-operative regime. For ruptured AAA, survival of the patient depended on a successful and timely operation. It was also concluded that no patient should be deemed unfit for surgery or denied an operation if they needed to have one and it was safe to transport patients with ruptured AAA to a centre where the operation can be performed.

Fulltext Multimodal approach in the management of 1163 ureteric stone cases

Tan HM, Liew RP, Chan CC, Wong AT, Ngun KW

Med J Malaysia, 1995 Mar;50(1):87-92.
PMID: 7752983

One thousand one hundred and sixty three patients (male-852, female-311) with ureteric calculi requiring intervention were treated between April 1988 to July 1992. Four hundred and eleven cases were treated by ESWL Monotherapy, 414 by stone manipulation plus ESWL, 301 by retrograde ureteroscopic lithotripsy, 36 by percutaneous antegrade ureteroscopic lithotripsy and 1 case by open ureterolithotomy. There were 25 failures of the initial procedures. Only three cases that failed primary procedures required open surgery. Other complications include minor ureteric mucosal perforation (3%), infection (3%), transient moderate to gross haematuria (20%), loin ache (26.4%), irritative urination (34.4%) and low grade fever (30.1%). Current modalities used in the treatment of ureteric calculi produce good results and there is generally no primary role for any open surgery.

Fulltext Early results of total knee replacements: "a clinical and radiological evaluation"

Dhillon KS, Jamal A, Bhupinderjeet S

Med J Malaysia, 1993 Dec;48(4):427-35.
PMID: 8183167

From March 1986 to June 1992, 100 primary total knee arthroplasties were done in 69 patients. The demographic data and complications were analysed in these 69 patients. The first 50 knees with a minimal follow-up of one year (range 1-6 years) were analysed in more detail according to the International Knee Society Rating System. Detailed radiological evaluation was also carried out to assess positioning of the components. There were 79 knees with osteoarthritis, 20 knees with rheumatoid arthritis and one with Systemic Lupus Erythromatosus (SLE). The knee score was poor in all knees pre-operatively. Post-operatively 78% had good to excellent score and the other 22% had fair knee score. However the functional score remained poor in 50% of the knees. Ideal tibio-femoral alignment was obtained in 68% of the knees. Twenty four percent of the knees had 0.4 degrees of varus and eight percent had 10-12 degrees valgus. Complication rate was low with 1% of infection (one knee). Overall early results were satisfactory.

Fulltext Effect of gender and age on fasting serum growth hormone levels in normal subjects

Nazaimoon WM, Ng ML, Osman A, Tan TT, Wu LL, Khalid BA

Med J Malaysia, 1993 Sep;48(3):297-302.
PMID: 8183142

Fasting growth hormone (GH) level is an important reference level in dynamic tests of GH secretion. Other studies have demonstrated sex and age variation in the rate of GH secretion. We analysed fasting serum samples from 377 normal subjects (193 males and 184 females, age range 6 to 81 years old), using our in-house enzyme immunoassay. We found sex differences in fasting GH levels to be only significant in the prepubertal children (Tanner stage I), being higher in girls than in age-matched boys (p < 0.05). Both sexes showed age-dependent changes in fasting GH levels (p < 0.001); highest levels were achieved at puberty and subsequently declined with advancing age. Hence, the physiological sex difference and age-dependency in GH secretion can also be demonstrated in single fasting samples.

Fulltext Continuous spinal anaesthesia--early experience in University Hospital, Kuala Lumpur

Vijayan R, Chan L, Raveenthiran R

Med J Malaysia, 1995 Dec;50(4):401-10.
PMID: 8668064

Continuous spinal anaesthesia using the incremental technique was used in nineteen high risk patients with multiple medical problems, seventeen of whom were elderly, for lower limb orthopaedic and pelvic surgery. An intrathecal catheter (18G/28G) was inserted under local anaesthesia via the lumbar interspinous space. Spinal anaesthesia was induced with small incremental doses of 0.5% bupivacaine hydrochloride through the intrathecal catheter to achieve the level of analgesia required for surgery. The duration of surgery ranged from 45 to 300 minutes (mean + S.D 100 + 37 min). The initial volume of 0.5% bupivacaine required for surgery ranged from 0.8 ml-2.0 ml (1.2 + 0.7 ml) and the total volume ranged from 0.9 ml to 3.1 ml (mean + S.D 1.4 + 0.7 ml). Haemodynamic stability was well maintained perioperatively. Only two patients required 6 mg of ephedrine and 1 mg of aramine respectively for a greater than 25% reduction in systolic blood pressure with induction of spinal anaesthesia. Intrathecal morphine 0.1-0.3 mg was administered to 15 patients at the end of surgery for postoperative pain relief with good effect. One patient developed late respiratory depression from an inadvertent overdose of intrathecal morphine. No neurological sequelae were noted and no patient developed a postdural puncture headache. The use of the microcatheter was discontinued in the U.S.A and Australia following four case reports of cauda equina syndrome with this technique. Current opinion, however, is that the reported cauda equina syndrome was due to the neurotoxic effects of lignocaine 5% that was used and not due to the microcatheter per se. Continuous spinal anaesthesia is now used widely in Europe when cardiovascular stability is desired in poor risk patients undergoing lower limb and lower abdominal surgery.

Fulltext Experience of radioactive needle implants in the Institute of Radiotherapy Hospital Kuala Lumpur

Lim GC, Azhar MT

Med J Malaysia, 1997 Mar;52(1):33-7.
PMID: 10968051

This retrospective study of radioactive needle implants at the Institute of Radiotherapy and Oncology, Kuala Lumpur Hospital serves as an audit of our practice as well as a demonstration of the usefulness of this technique of brachytherapy. A variety of tumour sites were implanted, of which over two-thirds involved the tongue and buccal mucosa. Although most of the implants were carried out with radical intent, one-tenth of these implants were performed for palliation. Radiotherapy techniques employed are described. The crude survival ranged from 1 month to 109 months while the disease free interval ranged from 0 months to 102 months.

Fulltext Oxygen consumption--a comparison between calculation by Fick's principle and measurement by indirect calorimetry

Cheong KF, Lee TL

Med J Malaysia, 1997 Mar;52(1):70-5.
PMID: 10968056

Oxygen consumption values calculated by Fick's principle (cVO2) were compared to simultaneously obtained values measured by indirect calorimetry (mVO2) in two groups of patients; post-coronary artery bypass graft (post-CABG) and septic shock. In both groups of patients, oxygen consumption values derived using indirect calorimetry were higher than that from Fick's principle. Whilst the bias obtained between the two methods of measurement were of acceptable amount clinically, the limits of agreement were wide: -57 to 51 ml.min-1.m-2 in the post-CABG group and -101 to 67 ml.min-1.m-2 in the group of septic patients; indicating that significant differences exist between paired individual values such that cVO2 and mVO2 were not interchangeable in this study.

Fulltext A personal experience with the first 100 TURP at the Penang General Hospital

Yeoh N, Inbasegaran K

Med J Malaysia, 1989 Jun;44(2):129-33.
PMID: 2483248

Transurethral Resection of the Prostate (TURP) is now the preferred method for dealing with the obstructing prostate. This procedure was reintroduced to the Penang General Hospital in August 1985. Over the next one and a half years, 100 TURP were performed by the author (NYTL). This paper reviews this initial experience. Of the patients, 17.7% required blood transfusion of one unit each. The mean post operative stay was 4.8 days. There were no immediate deaths. This experience confirms the acceptable results of TURP in the treatment of patients with benign prostatic hypertrophy in the Malaysian context.

Fulltext Myocardial infarction, circadian rhythm and delay in hospital admission

Quek DK, Ong SB, Lim LY

Med J Malaysia, 1989 Mar;44(1):14-22.
PMID: 2626108

Circadian variations have been observed in the onset of acute coronary syndromes including acute myocardial infarction. We studied 422 acute myocardial infarction patients who presented to the coronary care unit of General Hospital Kuala Lumpur. Of the 318 (75.4%) patients whose data was complete, a circadian rhythm with bimodal peak was demonstrated. The second quarter of the day i.e. 6.00 a.m. to 12 noon was shown to have a significantly increased frequency of onset of acute myocardial infarction (p less than 0.05). Time delay in presenting to the hospital was also determined. This showed that 56.8% of acute myocardial infarction patients presented early, within four hours of the onset of symptoms. By six hours, more than 71% had sought hospital care. This early presentation to the hospital may offer a realistic opportunity for optimal thrombolytic therapy should this treatment modality be offered as routine to infarct patients.

Fulltext Renal papillary necrosis in Ipoh

Segasothy M, Thyaparan A, Sivalingam S, Kamal A, Vijaya Kumar R

Med J Malaysia, 1986 Mar;41(1):19-23.
PMID: 3796342

594 intravenous urograms done at the General Hospital, Ipoh, from January 1981 to March 1985 were reviewed for renal papillary necrosis (RPN). 11 cases (1.8%) of RPN were detected. Of these three were due to diabetes mellitus;eight were due to analgesic nephropathy. There was an equal incidence
in males and females, contrary to the experience in the West and Australia. RPN was observed mainly in the older age groups. Five of the 11 cases of RPN presented as renal colic.

Caregiving burden is associated with short rather than long duration of care for older persons

Zainuddin J, Arokiasamy JT, Poi PJ

Asia Pac J Public Health, 2003;15(2):88-93.
PMID: 15038681 DOI: 10.1177/101053950301500203

This is a preliminary cross-sectional study of 51 caregivers of older persons attending the Geriatric Clinic at an urban hospital in Kuala Lumpur, Malaysia. A questionnaire helped determine how the duration of caregiving affects the outcome of caregiver burden. The short version of Zarit's Burden Interview (BI) allowed the burden level to be grouped as low or high burden. The duration of caregiving was also grouped into short (two or less years) or long (more than two years) durations. One third of the caregivers, 31% (16 out of 51) reported high burden and within this group 81%, (13 out of 16) are short duration caregivers. Majority of the longer duration caregivers, 88% (21 out of 24) reported low level of burden. This was a significant finding (p-value 0.008). The study also showed that a higher proportion of caregivers are employed, working in the private sector, and earn less than RM2,000 per month. However, these findings were not significantly associated with high burden. It is concluded that although this study showed low level of caregiver burden, shorter duration of caregiving is associated with higher level of burden and longer duration of caregiving is associated with lower level of burden.

Fulltext Iliotibial band tension reduces patellar lateral stability

Merican AM, Iranpour F, Amis AA

J Orthop Res, 2009 Mar;27(3):335-9.
PMID: 18925647 DOI: 10.1002/jor.20756

This study investigated the effect of loading the iliotibial band (ITB) on the stability of the patellofemoral joint. We measured the restraining force required to displace the patella 10 mm medially and laterally (defined as medial and lateral stability, respectively) in 14 fresh-frozen knees from 0 to 90 degrees knee flexion. The testing rig allowed the patella to rotate and translate freely during this displacement. The quadriceps was separated into five components and loaded with 175 N total tension. Testing was performed at 0 to 90 N ITB tension. With no ITB tension, the lateral restraining force ranged from 82 to 101 N across 0 to 90 degrees flexion. Increasing ITB tension caused progressive reduction of the lateral restraining force. The maximum reduction was 25% at 60 degrees flexion and 90 N ITB tension. Medial restraining force increased progressively with increasing knee flexion and increasing ITB loads; it ranged from 74 N at 0 degrees knee flexion and 0 N ITB tension to 211 N at 90 degrees knee flexion and 90 N ITB tension. The maximum effect was an increase of medial restraining force of 50% at 90 degrees flexion and 90 N ITB tension.

Fulltext Femoral fracture type can be predicted from femoral structure: A finite element study validated by digital volume correlation experiments

Ridzwan MIZ, Sukjamsri C, Pal B, van Arkel RJ, Bell A, Khanna M, et al.

J Orthop Res, 2018 03;36(3):993-1001.
PMID: 28762563 DOI: 10.1002/jor.23669

Proximal femoral fractures can be categorized into two main types: Neck and intertrochanteric fractures accounting for 53% and 43% of all proximal femoral fractures, respectively. The possibility to predict the type of fracture a specific patient is predisposed to would allow drug and exercise therapies, hip protector design, and prophylactic surgery to be better targeted for this patient rendering fracture preventing strategies more effective. This study hypothesized that the type of fracture is closely related to the patient-specific femoral structure and predictable by finite element (FE) methods. Fourteen femora were DXA scanned, CT scanned, and mechanically tested to fracture. FE-predicted fracture patterns were compared to experimentally observed fracture patterns. Measurements of strain patterns to explain neck and intertrochanteric fracture patterns were performed using a digital volume correlation (DVC) technique and compared to FE-predicted strains and experimentally observed fracture patterns. Although loaded identically, the femora exhibited different fracture types (six neck and eight intertrochanteric fractures). CT-based FE models matched the experimental observations well (86%) demonstrating that the fracture type can be predicted. DVC-measured and FE-predicted strains showed obvious consistency. Neither DXA-based BMD nor any morphologic characteristics such as neck diameter, femoral neck length, or neck shaft angle were associated with fracture type. In conclusion, patient-specific femoral structure correlates with fracture type and FE analyses were able to predict these fracture types. Also, the demonstration of FE and DVC as metrics of the strains in bones may be of substantial clinical value, informing treatment strategies and device selection and design. © 2017 Orthopaedic Research Society.

Fulltext Evaluation of automated volumetric breast density software in comparison with visual assessments in an Asian population: A retrospective observational study

Rahmat K, Ab Mumin N, Ramli Hamid MT, Fadzli F, Ng WL, Muhammad Gowdh NF

Medicine (Baltimore), 2020 Sep 25;99(39):e22405.
PMID: 32991467 DOI: 10.1097/MD.0000000000022405

This study aims to compare Quantra, as an automated volumetric breast density (Vbd) tool, with visual assessment according to ACR BI-RADS density categories and to determine its potential usage in clinical practice.Five hundred randomly selected screening and diagnostic mammograms were included in this retrospective study. Three radiologists independently assigned qualitative ACR BI-RADS density categories to the mammograms. Quantra automatically calculates the volumetric density data into the system. The readers were blinded to the Quantra and other readers assessment. Inter-reader agreement and agreement between Quantra and each reader were tested. Region under the curve (ROC) analysis was performed to obtain the cut-off value to separate dense from a non-dense breast. Results with P value

Fulltext Coping Strategies among Malaysian Women with Recurrent Ovarian Cancer: A Qualitative Study

Lee YK, Praveena KA, Woo YL, Ng CJ

Asia Pac J Oncol Nurs, 2020 10 15;8(1):40-45.
PMID: 33426188 DOI: 10.4103/apjon.apjon_38_20

Objective: Ovarian cancer is one of the most common cancers among Malaysian women with high recurrence. Patients with recurrence are prone to emotional distress and are forced to cope with poor prognosis. This study aimed to explore the coping strategies employed by women with recurrent ovarian cancer in Malaysia, a developing multicultural country in Asia.
Methods: This was a qualitative study with patients diagnosed with recurrent ovarian cancer and receiving chemotherapy at a hospital gynecologic day-care unit. In-depth individual interviews were conducted with patients to explore how they coped with recurrence of ovarian cancer. Interviews were audio-recorded, transcribed verbatim, and analyzed thematically.
Results: The participants' (n = 10) age range was 52-84 years, the three most common ethnic backgrounds were represented (Malay, Chinese, and Indian), and most of the patients were well educated. All patients were on chemotherapy. Six coping strategies were identified: (1) maintaining a mindset of hopefulness, (2) avoidance of information, (3) accepting their condition, (4) seeking spiritual help, (5) relying on family for support, and (6) coping with financial costs.
Conclusions: Coping strategies employed during ovarian cancer recurrence in this setting were rarely based on the accurate information appraisal, but rather on the individual emotion and personal beliefs.
