The management of solitary thyroid nodules under local anaesthesia

Cunningham IG, Lee YK

Aust N Z J Surg, 1975 Aug;45(3):285-9.
PMID: 1058690

A group of patients with solitary nodules of the thyroid were treated at the University of Malaya by surgery under local anaesthesia. This was done in order to expedite exploration of a potentially malignant condition. This group comprised 43 patients, and four cancers were found. The standard technique used was satisfactory from the viewpoint of both the patient and the surgeon. The pattern of this condition in a Malaysian population is documented, the technique used is described, and thyroidectomy under local aneaesthesia is discussed.

Locomotion and posture of the Malayan siamang and implications for hominoid evolution

Fleagle JG

Folia Primatol., 1976;26(4):245-69.
PMID: 1010498

Wild, adult siamang were observed for over 800 h in lowland dipterocarp forest in the Krau Game Reserve, Pahang, West Malaysia. Siamang use four patterns of locomotion: brachiation, climbing, bipedalism and leaping. The pattern of locomotion used by the siamang varies with the size of arboreal supports and with major behavioral activity. Travel is primarily by brachiation along large boughs. Locomotion during feeding is primarily climbing among small branches. In feeding, siamang use suspensory postures among small supports and seated postures on large supports. Comparison of siamang locomotion and posture with that of other apes suggest that quadramanous climbing during feeding is the basic hominoid locomotor adaptation.

Fulltext Spinal analgesia and headache at Penang General Hospital

Inbasegaram K, Yong BH

Med J Malaysia, 1985 Sep;40(3):233-8.
PMID: 3842718

One hundred (100) consecutive patients who underwent spinal analgesia for surgical and orthopaedic operations were studied. Postural headache occurred in 9% of patients, the majority in those cases where large bore (l8G to 21G) needless were used. No other neurological complications were encountered. Conservative measures provided some relief of the headache. Epidural blood patch was found to be effective.

Fulltext Postural behaviour of intraocular pressure

Singh M, Chin SSH

Med J Malaysia, 1986 Mar;41(1):38-43.
PMID: 3796346

Raised intraocular pressure (lOP) is generally held responsible for causing visual loss in chronic simple glaucoma. It is therefore desirable that a safe level of lOP be maintained all the time. Elevation of lOP with change of body position has been suggested as one of the factors which result in tissue damage in low tension as well as in primary wide open angle glaucoma. Postural behaviour of lOP was therefore studied in 58 normal and 30 glaucomatous Malaysian eyes. Clinical significance and possible pathogenesis of abnormal postural response of lOP has been discussed. More application of this simple procedure is advocated.

Fulltext Opium addiction and cauliflower ears: a case report

Muthusamy E

Singapore Med J, 1991 Feb;32(1):90-1.
PMID: 2017717

The case of an elderly Chinese male opium addict with cauliflower ears is discussed. He had no history of contact sports that could have led to auricular trauma resulting in deformed ears. Besides cauliflower ears, he had features of chronic bronchitis. The association between opium addiction and cauliflower ears was first described way back in 1932. It was attributed to the prolonged opium induced sleep on hard surface subjecting the ears to repeated pressure and trauma. With the changing pattern of drug abuse, opium abuse related cauliflower ears will become a vanishing sign.

Postural behaviour of intraocular pressure following trabeculoplasty

Singh M, Kaur B

Int Ophthalmol, 1992 May;16(3):163-6.
PMID: 1452420

Postural behaviour of intraocular pressure (IOP) was studied in 29 glaucomatous eyes before and after argon laser trabeculoplasty (ALT) and compared with that of 60 normal eyes. Although argon laser trabeculoplasty was successful in lowering the IOP below 21 mm Hg, it produced little effect on the postural behaviour of the IOP. No significant change was observed in the amplitude of postural rise of IOP in ALT treated eyes.

Fulltext Ergonomic task analysis in electronics industries: some case studies

Tan GL

J Hum Ergol (Tokyo), 1996 Jun;25(1):49-62.
PMID: 9551132 DOI: 10.11183/jhe1972.25.38

The analyses of a few tasks were carried out in an electronics factory. The main objectives are to identify the ergonomic and biomechanical hazards of problem work tasks, to analyze each task systematically in order to evaluate the workers' exposures to the risk factors of force, posture pressure and repetition and to make recommendations to reduce the risks and hazards. The methodology includes objective measures--detailed analysis by going through training manuals, job description and production records. Subjective measures include interviewing the operator and supervisors informally, the operators were also required to fill in a structured questionnaire. The paper concludes by making recommendations to reduce the ergonomic hazards by engineering solutions, redesign or administrative controls or the implementation of procedures.

Fulltext Cannulation of internal jugular vein in neutral head position

Lew YS, Lim SK

Med J Malaysia, 1998 Sep;53(3):227-31.
PMID: 10968158

An approach to cannulate right internal jugular vein in neutral head position is described for situations where head rotation and extension are contraindicated. Venous puncture was made immediately lateral to the carotid artery at the level of cricoid cartilage and directed caudad. In 40 patients studied, the right internal jugular vein of 97.5% of the patients were successfully located by the finder needle. The mean (SE) number of puncture attempts to locate the vein was 1.3 (0.1) per patient. In 72.5% (29 patients), the veins were located exactly at the predicted point after the first attempt. However the overall success rate for cannulation by the angiocath cannula was 87.5% and short term complication rate was 5.0%. We conclude this technique is a reliable, safe alternative for central venous access, especially in patients where cervical spine movement is contraindicated or restricted.

Heterophil to lymphocyte ratio and tonic immobility reactions to preslaughter handling in broiler chickens treated with ascorbic acid

Zulkifli I, Che Norma MT, Chong CH, Loh TC

Poult Sci, 2000 Mar;79(3):402-6.
PMID: 10735209

Stress and fear responses were evaluated in broiler chicks that were pretreated for 24 h with 0 ppm (control) or 1,200 ppm of L-ascorbic acid (AA) in their drinking water. The birds were subsequently subjected to either upright handling (UH) or inverted (IH) handling for about 45 s. Heterophil (H) counts, lymphocyte (L) counts, and H/L ratios (H/L) ratios were determined immediately (T0) and at 20 h (T20) following the handling treatment. The H/L ratios were similar for both groups at T0, whereas 20 h after the handling treatment, AA-supplemented birds had lower ratios than controls, resulting in a significant water treatment x time of blood sampling interaction. Inverted handling had negligible effect on H/L ratios but augmented tonic immobility (TI) durations as compared with UH. Irrespective of handling procedure, supplemental AA reduced underlying fearfulness, as measured by TI reaction. Neither water treatment nor handling method had significant effect on number of attempts to induce TI.

Ethnic differences in response to non-selective beta-blockade among racial groups in Malaysia

Rasool AH, Rahman AR, Ismail R, Hatim S, Abdullah AR, Singh R, et al.

Int J Clin Pharmacol Ther, 2000 May;38(5):260-9.
PMID: 10839470

OBJECTIVE: To determine whether racial differences in response to blockade of beta receptors occur among racial groups in Malaysia that are the Malays, Indians and Chinese. SUBJECTS, MATERIALS AND METHOD: 35 healthy male volunteers representing the 3 main racial groups in Malaysia (12 Malays, 12 Chinese and 11 Indians) were studied in a randomized, placebo-controlled, crossover and single-blind design. Propranolol 80 mg 12-hourly was given orally for 48 hours. Six hours after the last dose subjects attended an exercise session where resting and exercise heart rate, blood pressure, plasma potassium and glucose levels, resting FEV1 and plasma propranolol concentrations were recorded.
RESULTS: No significant difference in plasma propranolol (mean +/- SEM) levels was seen between races six hours after the last dose (Malays, 59.7 +/- 8.8 ng/ml, Indians, 67.6 +/- 19.3 ng/ml, Chinese, 58.4 +/- 7.9 ng/ml). Chinese were least sensitive to the bradycardic and hypotensive effects of propranolol at rest and exercise. Indians and Malays had significant reduction of supine systolic blood pressure with propranolol but not Chinese. Comparison of percentage reductions of systolic blood pressure at supine, sitting and exercise by repeated measure analysis showed the Malays to have significantly higher change compared to the Chinese (p = 0.022). Similarly, comparison of percentage reductions of heart rate at supine, sitting and exercise by repeated measure analysis showed the Malays to have significantly higher change compared to the Chinese (p = 0.040). Average change in potassium concentrations at peak exercise and recovery showed the Indians to have significantly higher increase in potassium levels with propranolol compared to the Malays (p = 0.038). However, no significant interethnic difference was seen in the reduction of glucose levels at rest, peak exercise or recovery. Also, no significant interethnic difference was seen in reduction of FEV1 values.
CONCLUSION: We, therefore, conclude that ethnic differences in response to blockade of beta-receptors exist among racial groups in Malaysia. These differences were seen at similar plasma drug levels between races suggesting ethnic differences in drug sensitivity, rather than differences in drug disposition.

Fulltext Dynamic measurement of axial vertebral rotation and rotational flexibility in scoliosis by flouroscopic method

Lim HH, Ong CH

Med J Malaysia, 2001 Jun;56 Suppl C:41-5.
PMID: 11814248

The Pedriolle torsion meter is an established method of vertebral rotation assessment in scoliosis. However, the assessment of scoliosis by this method is static and indirect. The objective of this study is to compare the accuracy of a direct method of assessing scoliosis rotation by fluoroscopy compared to the Pedriolle torsion meter. Secondly, to determine that vertebral body rotation changes with supine posture compared to erect position. Eight volunteers with idiopathic scoliosis were assessed for the apical vertebral rotation with this method and the Pedriolle torsion meter. These patients were also assessed in the supine and erect position with the fluoroscopic method to determine if the apical vertebral rotation would change with posture. The mean Cobb angle of the curves was 62.8 degrees (range 45 degrees to 86 degrees). The mean apical vertebral rotation in a standing position was assessed to be 21.5 degrees by Pedriolle torsion meter and 29 degrees by the fluoroscopic method. This difference was not statistically significant by the student t-test. In most patient, the rotation of vertebrae improved by a varying degree ranging from none to 24 degrees in the supine position. In conclusion, the fluoroscopic method is an alternate mean of measuring vertebrae rotation in idiopathic scoliosis, with comparable accuracy to the Pedriolle torsion meter method. The amount of vertebral rotation changes with posture of the patient.

Fulltext The prevalence of musculoskeletal problems and risk factors among women assembly workers in the semiconductor industry

Chandrasakaran A, Chee HL, Rampal KG, Tan GLE

Med J Malaysia, 2003 Dec;58(5):657-66.
PMID: 15190650

A cross-sectional study to determine work-related musculoskeletal problems and ergonomic risk factors was conducted among 529 women semiconductor workers. Overall, 83.4% had musculoskeletal symptoms in the last one year. Pain in the back (57.8%), lower leg (48.4%) and shoulder (44.8%) were the three most common musculoskeletal problems. Significant associations were found between prolonged standing and upper and lower leg pain, between prolonged sitting and neck and shoulder pain and between prolonged bending and shoulder arm, back and upper leg pain. The study therefore showed a clear association between work-related musculoskeletal pain and prolonged hours spent in particular postures and movements.

Journal of Occupational Safety and Health, 2004;1(2):42-48.
MyJurnal

This paper presents the use of factorial experiments and response surface methodology to determine the best workstation design configuration of an existing electronic industry. The aim is to find the value of physical dimensions that gives the best performance for the workstation. Four performance measures are selected; the cycle time, the metabolic energy expenditure, worker’s posture during the task and lifting limitations. The methodology used in this study consists of two parts. The first part is based on factorial experiments and handles discrete search over combinations of factor-levels for improving the initial solution. In the second part, the solution that was obtained earlier is further refined by changing the continuous factors by using response surface methodology. The result of this optimization study shows that the optimum value of physical dimensions gives a significant improvement for the performance measures of the workstation.

Craniofacial morphology, head posture, and nasal respiratory resistance in obstructive sleep apnoea: an inter-ethnic comparison

Wong ML, Sandham A, Ang PK, Wong DC, Tan WC, Huggare J

Eur J Orthod, 2005 Feb;27(1):91-7.
PMID: 15743868

The aim of this study was to measure craniofacial morphology and nasal respiratory resistance (NRR) in Malay, Indian and Chinese subjects with obstructive sleep apnoea (OSA). The sample consisted of 34 male subjects, 27-52 years of age (Malay n = 11, which included five mild and six moderate-severe OSA; Indian n = 11, which included six mild and five moderate-severe OSA; and Chinese n = 12, which included six mild and six moderate-severe OSA) diagnosed using overnight polysomnography. After use of a decongestant, NRR was recorded using anterior and posterior rhinomanometry. Standardized lateral cephalometric radiographs were used to record linear and angular dimensions. Malay subjects with moderate-severe OSA had a shorter maxillary (sp-pm) and mandibular (gn-go) length when compared with a mild OSA reference sample (P < 0.05). The hyoid bone was located more caudally in the Chinese moderate-severe subjects (hy-NL, hy-ML)(P < 0.05), and may be a useful diagnostic indicator for severity in this racial group. No pattern of differences for NRR was seen between the moderate-severe and mild OSA subjects. The consistently lower values for nasopharyngeal resistance in all the moderate-severe subjects when compared with the mild group may indicate that some compensation at this level of the airway had taken place. Strong positive correlations between craniocervical angulation (NL/OPT) and total airway resistance and the turbulent component of flow (k(2)) suggest that head posture is sensitive to fluctuations in airway resistance (P < 0.01).

Fulltext Forequarter amputation of the upper extremity for musculoskeletal tumors: posterior approach revisited

Faisham WI, Zulmi W, Nor Azman MZ, Rhendra Hardy MZ

Med J Malaysia, 2006 Feb;61 Suppl A:57-61.
PMID: 17042232

Forequarter amputation entails surgical removal of entire upper extremity, scapula and clavicle. Several techniques of forequarter amputation have been described. The anterior approach has been the preferred technique of exploration of axillary vessels and brachial plexus. The posterior approach has been condemned to be unreliable and dangerous for most large tumor of the scapula and suprascapular area. We describe a surgical technique using posterior approach of exploration of major vessels for forequarter amputation of upper extremity in eight patients who presented with humeral-scapular tumor. There were six patients with osteosarcoma: three with tumor recurrent and three chemotherapy recalcitrant tumors with vessels involvement. One patient had massive fungating squamous cell carcinoma and another had recurrent rhabdomyosarcoma. Four patients had fungating ulcer and six patients had multiple pulmonary metastases at the time of surgery. The mean estimated blood transfusion was 900 ml (range 0-1600 ml) and two patients did not require transfusion. The duration of surgery ranged 2.5-6.0 hours (mean 3.8 hours). Two patients with known pulmonary metastases required post-operative intensive care monitoring. The mean duration of survival was 5.8 months. The posterior approach of exploring major vessels for forequarter amputation of upper extremity with musculoskeletal tumor is safe and reliable.

PMID: 17485871

To determine the risk factors associated with complain of low back pain. A cross sectional study was done from June 2004 until August 2005. Seven hundred and sixty commercial vehicle drivers from 11 bus companies in central, northern and eastern regions in Malaysia participated in this study. Modified Nordic questionnaire was used to determine the prevalence of low back pain; Maestro human vibration meter was used to measure the personal R.M.S values of lateral, anterior-posterior and vertical axes. Modified Owas was used to assess the awkward posture of the driver torso namely, bending forward movement, leaning, sitting straight and twisting. Profile of Mood States (POMS) was used to evaluate the mood states of bus drivers with complain of low back pain. A high prevalence of low back pain (60.4%) among Malaysian commercial vehicle drivers was found. Logistic regression analysis controlling for age, income, education level and non occupational activities revealed that the following factors were related to low back pain: Tension-anxiety [1.080, 95% CI 1.041-1.121], depression dejection [1.047, 95% CI 1.023-1.072], anger-hostility [1.053, 95% CI 1.027-1.081], fatigue [1.132, 95% CI 1.089-1.177] and confusion [1.114, 95% CI 1.061-1.169] of POMS, length of employment [1.001, 95% CI 1.0-1.003], steering wheel adjustment [1.521, 95% CI 1.101-2.101], perception of exposing to vibration [1.943, 95% CI 1.389-2.719]. In conclusion, combinations of risks lead to high increase of low back pain complain among Malaysian bus drivers.

Low back pain (LBP) is a major medical and social problem associated with disability and work absenteeism. Since the effect on unawareness on back care among hospital staff may affect the smooth running of the services to the public and patients, it is the objective of this study to identified the awareness of back care among nurses so that preventive measures can be taken. About 80 nurses working in the outpatient clinic was survey using self addressed questionnaires which were adapted from Zutphen Physical Activity Questionnaire at Queen Elizabeth Hospital, Kota Kinabalu. Demographic analysis demonstrated that among the eighty nurses that responded, 37.5% (n=30) are Malays, 25% (n=25) Chinese and 37.5% (n=30) ( to include other Sabahan tribes). Their age group varies between 23 to 55 years of age. A total of 72 nurses, both agreed (45%,n=36) and strongly agreed (45%,n=36) that understanding good postures is important to prevent LBP. They felt strongly (55%, n=44) about the importance of correct lifting techniques, and having a well-designed workplace (50%,n=40). Regarding factors that cause LBP, 55% (n=44) of them strongly agreed that good lifting technique can prevent LBP while 56 (70%) agreed that prolong sitting doing computer work can cause LBP. About 60% (n=48) also agreed that LBP can cause stress and that 45% (n=36) of them strongly agreed that being overweight than average can worsen LBP. However, 40% (n=32) provide a neutral answer to whether height have any influence on LBP while 50% (n=40) agreed that weak back muscles can worsen the backache further. However, 45% (n=36) agreed that games that involved back movement have high risks and 55% (n=44) agreed that swimming helps to strengthen back muscle. The environmental factors addresses issues of footwear and soft mattress where 60%(n=48) agreed while 15%(n=12) strongly agreed that good footware and appropriate use of soft mattresses 60% (n=48) can prevent LBP. This study have demonstrated that the nurses that participated had a clear understanding and knowledge on back care even though a wider study need to be carried out to ensure validity of study finding.

Understanding ergonomics: a practical approach for improving workplace safety and health

Zafir M.M., Fazilah M.H.

Journal of Occupational Safety and Health, 2007;4(1):19-27.
MyJurnal

Ergonomics management is a process that will have a significant, positive effect on a company’s profits through cost reduction, quality improvement, performance improvement and productivity enhancement. Also known as human factors of human engineering, it basically describes the interaction between an employee and his/her job functions, with the emphasis being on reducing unnecessary physical stress in the workplace. The goal of ergonomics is to enable workers to be more effective by matching the requirements and demands of the job to the abilities and limitations of the workers rather than trying to force the workers to fit the job. This paper theoretically describes the benefits of understanding the ergonomics to the workplace. The components and activities required to implement ergonomics management also have been discussed. Besides that, the practical approach of ergonomics has been described by giving practical workplace improvement suggested by scholars. By approaching work practices (stretching, reaching, and sitting) from an ergonomically correct point of view, a worker actually becomes stronger, healthier and more productive.
