BACKGROUND: Muscle injuries are one of the commonest injuries affecting athletes. It often leads to significant pain and disability causing loss of training and competition time. With current treatment, the duration to return-to-play ranges form six weeks to never, depending on injury severity. Recent researches have suggested that autologous platelet-rich plasma (PRP) injection into the injured site may hasten soft tissues healing. To-date, there has been no randomised clinical trials to evaluate the effects of PRP on muscle healing. The aim of this study is to examine the effects of autologous PRP on duration to return-to-play after muscle injury.

METHODS AND DESIGN: A randomised, single blind controlled trial will be conducted. Twenty-eight patients aged 18 years and above with a recent grade-2 hamstring injury will be invited to take part. Participants will be randomised to receive either autologous PRP injection with rehabilitation programme, or rehabilitation programme only. Participants will be followed up at day three of study and then weekly for 16 weeks. At each follow up visit, participants will be assessed on readiness to return-to-play using a set of criteria. The primary end-point is when participants have fulfilled the return-to-play criteria or end of 16 weeks.The main outcome measure of this study is the duration to return-to-play after injury.

CONCLUSION: This study protocol proposes a rigorous and potential significant evaluation of PRP use for grade-2 hamstring injury. If proven effective such findings could be of great benefit for patients with similar injuries.

Ng YG, Shamsul Bahri MT, Irwan Syah MY, Mori I, Hashim Z

J Occup Health, 2014;55(5):405-14.

PMID: 23892641

OBJECTIVES: Production agriculture is commonly associated with high prevalence of ergonomic injuries, particularly during intensive manual labor and during harvesting. This paper intends to briefly describe an overview of oil palm plantation management highlighting the ergonomics problem each of the breakdown task analysis.

METHODS: Although cross-sectional field visits were conducted in the current study, insight into past and present occupational safety and health concerns particularly regarding the ergonomics of oil palm plantations was further exploited. Besides discussion, video recordings were extensively used for ergonomics analysis.

RESULTS: The unique commodity of oil palm plantations presents significantly different ergonomics risk factors for fresh fruit bunch (FFB) cutters during different stages of harvesting. Although the ergonomics risk factors remain the same for FFB collectors, the intensity of manual lifting increases significantly with the age of the oil palm trees-weight of FFB.

CONCLUSIONS: There is urgent need to establish surveillance in order to determine the current prevalence of ergonomic injuries. Thereafter, ergonomics interventions that are holistic and comprehensive should be conducted and evaluated for their efficacy using approaches that are integrated, participatory and cost-effective.

PMID: 23717593 DOI: 10.1371/journal.pone.0064308

Use of functional knee braces has been suggested to provide protection and to improve kinetic performance of the knee in Anterior cruciate ligament(ACL)-injured patients. However, many athletes might refrain from wearing the braces because of the fear of performance hindrance in the playing field. The aim of this study was to examine the effect of three functional knee brace/sleeves upon the isokinetic and functional performance of ACL-deficient and healthy subjects. Six anterior cruciate ligament deficient (29.0 ± 5.3 yrs., 175.2 ± 5.4 cm, and 73.0 ± 10.0 kg) and six healthy male subjects (27.2 ± 3.7 yrs., 176.4 ± 6.4 cm, and 70.3 ± 6.9 kg) were selected. The effect of a custom-made functional knee brace, and two neoprene knee sleeves, one with four metal supports and one without support were examined via the use of isokinetic and functional tests in four sets (non-braced,wearing functional knee brace,and wearing the sleeves). Cross-over hop and single leg vertical jump test were performed and jump height, and hop distance were recorded. Peak torque to body weight ratio and average power in two isokinetic velocities(60°.s(-1),180°.s(-1)) were recorded and the brace/sleeves effect was calculated as the changes in peak torque measured in the brace/sleeves conditions, expressed as a percentage of peak torque measured in non-braced condition. Frequency content of the isokinetic torque-time curves was also analyzed. Wilcoxon signed rank test was used to compare the measured values in four test conditions within each control and ACL-deficient group,and Mann-Whitney U test was used for the comparison between the two groups. No significant differences in peak torque, average power, torque-time curve frequency content, vertical-jump and hop measurements were found within the experimental and the non-braced conditions (p>0.05). Although the examined functional knee brace/sleeves had no significant effect on the knee muscle performance, there have been some enhancement regarding the extension peak torques and power generating capacity of the ACL-deficient subjects that could be helpful in reducing the bilateral asymmetry in these patients.

Hassan R, Abd Aziz A, Mohamed SKC

Med J Malaysia, 2012 Aug;67(4):445-51; quiz 452.

PMID: 23082464 MyJurnal

Computed tomography (CT) is currently the diagnostic modality of choice in the evaluation of clinically stable patients with blunt abdominal trauma, including the assessment of blunt bowel and mesenteric injuries. CT signs of bowel and/or mesenteric injuries are bowel wall defect, free air, oral contrast material extravasation, extravasation of contrast material from mesenteric vessels, mesenteric vascular beading, abrupt termination of mesenteric vessels, focal bowel wall thickening, mesenteric fat stranding, mesenteric haematoma and intraperitoneal or retroperitoneal fluid. This pictorial essay illustrates CT features of bowel and/or mesenteric injuries in patients with blunt abdominal trauma. Pitfalls in interpretation of images are emphasized in proven cases.

Fulltext The role of preoperative magnetic resonance imaging in internal derangement of the knee

Zairul-Nizam ZF, Hyzan MY, Gobinder S, Razak MA

Med J Malaysia, 2000 Dec;55(4):433-8.

PMID: 11221154

We attempted to compare the accuracy of our clinical examination and the usage of magnetic resonance imaging (MRI) in evaluating patients suspected of having internal derangement of the knee who were seen in our Orthopaedic clinic. This was done using the findings of arthroscopy as the 'gold standard'. The accuracy of MRI in detecting cruciate ligament tears was between 80-96% against 82-93% for clinical examination. MRI accuracy for meniscus injuries was 80-84% compared to 48-65% for clinical examination. We thus propose that MRI examination is an effective first-line investigation for patients with suspected internal knee derangement, especially menisci injuries; allowing arthroscopy to be reserved for patients in whom surgery is truly indicated.

Traumatized anterior teeth in children. A 24-month follow-up study

Rusmah M

Aust Dent J, 1990 Oct;35(5):430-3.

PMID: 2073190

The objectives of this Malaysian study were to investigate the relationship between severity of trauma and interval before treatment, and the effect of delayed treatment on prognosis. A total of 123 traumatized permanent incisors were observed over a 24-month period. Results of this study suggest that the interval between trauma and emergency treatment is directly related to the severity of injury and the level of dental awareness of the patients. However, prognosis of these teeth is greatly influenced by the interval between trauma and initial treatment. Pathological pulp changes in these teeth can occur as late as two years after injury and this justifies the necessity for a long observation period following treatment.

Brachial plexus injuries in Malaysian neonates: incidence and associated risk factors

Boo NY, Lye MS, Kanchanamala M, Ching CL

J Trop Pediatr, 1991 12;37(6):327-30.

PMID: 1791654 DOI: 10.1093/tropej/37.6.327

A prospective study was carried out on 26,176 Malaysian neonates born in the Maternity Hospital, Kuala Lumpur over a 12-month period to determine the incidence and associated risk factors of brachial plexus injuries. This condition was found in 42/26,176 neonates (1.6 per 1000 livebirths). Multiple logistic regression analysis of affected and control neonates from a nested case-control study showed that increasing birth weights and breech deliveries were the significant risk factors. Our study suggests that to reduce the occurrence of this condition, there is a need for: (i) better assessment of fetal size and maternal pelvimetry to enable earlier diagnosis of cephalo-pelvic disproportion, and (ii) review of the indications and techniques of breech delivery.

Fulltext Surgical intervention in traumatic facial nerve paralysis

Yeoh TL, Mahmud R, Saim L

Med J Malaysia, 2003 Aug;58(3):432-6.

PMID: 14750385

A four years review from June 1998 to June 2002 of traumatic facial nerve paralysis from temporal bone fractures that required surgical intervention is presented. The aim of this clinical presentation was to determine the current pattern of cases with traumatic facial paralysis which required surgical intervention at our center. There were six cases, of which four (66%) were longitudinal fractures, one each (17%) had transverse fracture and fracture over the lateral wall of mastoid. Hearing loss (83%) was the commonest associated clinical symptom. All cases underwent decompression via the transmastoid surgical approach. Intraoperative findings revealed oedema of facial nerve involving vertical segment and horizontal segment in three cases each respectively. Two cases had concomitant bony impingement. The facial nerve functions in four cases (66%) and one case recovered to House Brackmann grade 2 and 4, 12 months and 3 months respectively postsurgery. The case with transverse fracture remained as House Brackmann grade 5 after two years.

Traumatic abdominal wall hernia - a case of handlebar hernia

Vincent K, Cheah SD

Med J Malaysia, 2018 12;73(6):425-426.

PMID: 30647222

Traumatic abdominal wall hernia (TAWH) after blunt injury is uncommon. Diagnosis requires careful examination and high index of suspicion. We report a case of a 12-year-old boy who complained of painful abdominal swelling over the left iliac fossa after a bicycle-handlebar hit his abdomen. TAWH was diagnosed clinically and confirmed with ultrasound and computed tomography (CT) scan. He developed incarceration after 12 hours of admission and subsequently underwent primary repair without mesh. As TAWH is usually associated with other concomitant injuries, it is important that we are meticulous to rule out other serious concomitant injuries.

PMID: 28524750 DOI: 10.3171/2016.12.SPINE16586

Swordfish attacks on humans are uncommon, with only a few case reports available in the current literature. The authors report the first known case of a penetrating spinal injury from a swordfish, in which the patient presented with a small stab wound and hemiparesis. The presentation of a fisherman with hemiparesis and a harmless-looking stab wound must alert clinicians to the possibility of penetrating swordfish injuries to the spine.

PMID: 1631597

Retroperitoneal duodenal rupture due to blunt abdominal trauma is relatively uncommon. Diagnosis is difficult because the physical signs are subtle or they are difficult to interpret. A case of retroperitoneal duodenal rupture due to blunt abdominal trauma in whom the diagnosis was delayed is reported. Radiographic features are discussed. The role of early roentgen diagnosis is stressed in order to reduce the very high mortality which is associated with delay in diagnosis and treatment.

Blue ME, Wilson MA, Beaty CA, George TJ, Arnaoutakis GJ, Haggerty KA, et al.

J. Neuropathol. Exp. Neurol., 2014 Dec;73(12):1134-43.

PMID: 25383634 DOI: 10.1097/NEN.0000000000000134

Neuropathology and neurologic impairment were characterized in a clinically relevant canine model of hypothermic (18°C) circulatory arrest (HCA) and cardiopulmonary bypass (CPB). Adult dogs underwent 2 hours of HCA (n = 39), 1 hour of HCA (n = 20), or standard CPB (n = 22) and survived 2, 8, 24, or 72 hours. Neurologic impairment and neuropathology were much more severe after 2-hour HCA than after 1-hour HCA or CPB; histopathology and neurologic deficit scores were significantly correlated. Apoptosis developed as early as 2 hours after injury and was most severe in the granule cells of the hippocampal dentate gyrus. Necrosis evolved more slowly and was most severe in amygdala and pyramidal neurons in the cornu ammonis hippocampus. Neuronal injury was minimal up to 24 hours after 1-hour HCA, but 1 dog that survived to 72 hours showed substantial necrosis in the hippocampus, suggesting that, with longer survival time, the injury was worse. Although neuronal injury was minimal after CPB, we observed rare apoptotic and necrotic neurons in hippocampi and caudate nuclei. These results have important implications for CPB in humans and may help explain the subtle cognitive changes experienced by patients after CPB.
