A fatal nail gun injury--an unusual ricochet?

Nadesan K

Med Sci Law, 2000 Jan;40(1):83-7.
PMID: 10689867

An 18-year-old construction worker suddenly collapsed while handling a power-actuated nail gun and died shortly after. A neat, almost circular puncture wound was found on the front of his left chest. No fire-arm residues were detected on the surrounding skin. The police stated that it was an accidental injury, at a construction site, where a nail fired from a nail gun by the deceased had deflected off the wall and struck him on the front of the chest. Since the entry wound appeared to be a neat hole, and that too on the front of the left chest overlying the heart area, there was reluctance on the part of the pathologist to accept it as an accidental injury due to a ricochet. A visit to the scene, interrogation of witnesses, examination of the alleged tool and post-mortem X-ray of the deceased were undertaken prior to autopsy. A bent nail was found in the heart. The scene visit and the subsequent autopsy revealed that the nail took a roughly circular flightpath after it had struck the wall, all the while travelling with its pointed end directed forward. Within the body too, the nail maintained the same path. Various medicolegal issues are discussed pertaining to nail-gun injuries. The importance of a visit to the scene, examination of the alleged tool, interrogation of witnesses and the X-ray of the body, all prior to autopsy, are emphasized. The conclusion was: accidental death due to the unusual ricochet of a nail.

Fulltext Clinical profile of acute flaccid paralysis

Rasul CH, Das PL, Alam S, Ahmed S, Ahmed M

Med J Malaysia, 2002 Mar;57(1):61-5.
PMID: 14569719

This study was done to determine the clinical course, cause and outcome of Acute Flaccid Paralysis (AFP) in children. All AFP cases (< 15 years) in the children's ward of Khulna Medical College Hospital (Bangladesh) were recorded, investigated and followed up to sixty days as a part of passive surveillance. Main outcome variables were vulnerable age group, vaccine status, predominant limb involvement, clinical variants, virus isolation and residual paralysis. Thirty-four children with AFP were admitted in hospital in the last three years with the highest number (14) in 1998. The majority of children belonged to the age group 5-9 years with a male female ratio of 1.3:1. Nearly one third of the cases were either partially vaccinated or not vaccinated at all. The lower limbs bore the brunt of paralysis excepting a few (14.7%). Clinically, Guillain Barre Syndrome was the commonest (47.1%) followed by encephalomyelitis. No poliovirus was isolated from these cases. Residual paralysis was observed in four out of ten cases who returned for follow up. AFP will continue to occur even after eradication of poliomyelitis and Guillain Barre Syndrome is the most important clinical entity for this.

Total thyroidectomy: the procedure of choice for multinodular goitre

Hisham AN, Azlina AF, Aina EN, Sarojah A

Eur J Surg, 2001 Jun;167(6):403-5.
PMID: 11471662 DOI: 10.1080/110241501750243725

OBJECTIVE: To review our experience of total thyroidectomy for bilateral multinodular goitre.
DESIGN: Prospective open study.
SETTING: Teaching hospital, Malaysia.
SUBJECTS: 98 consecutive patients whose bilateral multinodular goitres were treated by total thyroidectomy, January 1998-November 1999.
INTERVENTION: A revised technique of total thyroidectomy in which more attention than is customary was paid to the exposure and safety of the laryngeal nerves and the parathyroid glands. All patients had at least 1 parathyroid gland autotransplanted.
MAIN OUTCOME MEASURES: Morbidity and mortality
RESULTS: There were no injuries to the recurrent laryngeal nerves and no patient developed persistent hypocalcaemia; 27/98 developed transient hypocalcaemia, but this had settled by 6 months postoperatively. 59 patients had persistent symptoms of pressure preoperatively, and these all resolved by 3 months postoperatively. 6 patients had occult malignant disease discovered on histological examination, and 3 developed minor wound infections.
CONCLUSIONS: Total thyroidectomy is the procedure of choice for bilateral multinodular goitres, provided that sufficient attention is paid to the preservation of the laryngeal nerves and the parathyroid glands.

Nutritional assessment of rural villages and estates in peninsular Malaysia: Total blood cholesterol values in children, adolescents and adults

Wai TN, Lin KG, Siong TE, Hashim N

Asia Pac J Clin Nutr, 2000 Jun;9(2):115-21.
PMID: 24394397

The present study is unique in the Malaysian context on two counts; first, it employs for the first time a functional group approach (groups based on occupational or economic activity) in the assessment of community nutritional status. Second, the study provides on a nationwide-sampling basis, information on total blood cholesterol (TC) levels in rural children (7.0-12.9 years; n = 1921) and adolescents (13.0-17.9 years; n = 753) which were hitherto unavailable. Total blood cholesterol measurements were performed on 7184 subjects ranging from 7 to 75-years-old (males = 3151; females = 4033) from households in 69 rural villages and seven estates in peninsular Malaysia, which were based on selected multistage random sampling according to the household's involvement in the following economic activities: rice farming, rubber smallholding, coconut smallholding, fishing and employment in estates. In all functional groups, TC values increased with age and there was a distinct gender effect, namely females had higher TC values than males throughout the age spectrum analyzed. Mean TC levels for children and adolescents were in the range 3.85-4.37 mmol/L, rising markedly during adulthood to an overall mean of 4.91 ± 1.13 mmol/L for men and 5.17 ± 1.11 mmol/L for women. In adults (>= 18.0 years), there was marked disparity in mean TC values among the functional groups; males and females from rice households had the lowest mean TC values (4.58 and 4.99 mmol/L, respectively). Individuals at 'high risk' (TC > 6.20 mmol/L) averaged 16.0% in women and 11.6% in men, with women from the fishing, rubber and coconut households particularly affected (17.1-21.1%). When compared to earlier rural TC data reported for closely similar rural communities in the peninsula, the present findings suggest a 'hypercholesterolemic shift' approximating 0.39 mmol/L (15 mg/dL) in the adult population; however, this was not apparent in the children and adolescents from these rural communities.

Hooi LS, Rozina G, Wan Shaariah MY, Teo SM, Tan CHH, Bavanandan S, et al.

Med J Malaysia, 2003 Mar;58(1):27-36.
PMID: 14556324

There were 72 pregnancies in 46 renal transplants (RTs) between 1984 and 2001, 89% from living donors, 11% cadaveric. Mean age at RT was 26.9 +/- 4.3 years and at pregnancy 30.7 +/- 4.7 years. Mean time to pregnancy after RT was 4.5 +/- 3.1 years. 54% were unplanned. 45 (63%) resulted in surviving infants, 37% delivered by Caesarean section. 35% were premature. Mean birth weight was 2.38 +/- 0.57 kg. 64% were on cyclosporine. No patient had an acute rejection during pregnancy; 38% had pre-existing hypertension. Complications include urinary infection (13%), proteinuria (15%) and preeclampsia (15%). Mean serum creatinine before pregnancy was 112.7 +/- 32.6 umol/l, 1 year post-pregnancy it was 119.4 +/- 38.7. The mean time of follow up of mothers is 4.9 +/- 3.5 years. 10 year graft survival was 83% and patient survival 94%.

Jaais F

Med J Malaysia, 1998 Sep;53(3):272-6.
PMID: 10968165

Secondary intraocular lens implantation after cataract surgery done in University Hospital between 1983 to 1993 were reviewed. Thirty three patients (37 eyes) underwent secondary intraocular lens implantation during this period. Twenty four eyes had secondary anterior chamber lens implantation while 13 had posterior chamber lens implantation. There was no case of secondary posterior scleral fixation lens implantation. Visual acuity of 6/9 or better was seen in 25 of 37 eyes (67%) in the series. Eyes seeing as good or better than before secondary implantation procedure were noted in 34 of 37 eyes (92%). Vision of 6/9 or better was seen in 9 of 13 eyes (70%) with posterior chamber implants and 16 of 24 eyes in (67%) with anterior chamber lenses. Complications including bullous keratopathy, uveitis and glaucoma were seen with anterior chamber implants of the rigid type resulting in poorer visual acuity than before the secondary procedure.

Determinants of breastfeeding duration in Peninsular Malaysia

Awang H, Salleh AL

Asia Pac J Public Health, 2000;12(2):102-6.
PMID: 11836918

The health benefits of breastfeeding to infants and mothers have been well recognised. This study applies linear regression analysis to assess the determinants of breastfeeding duration of first born using data from the Second Malaysian Family Life Survey. The proportion of women who breastfed their first child is 82 percent, of which 97 percent reported their breastfeeding duration. The distribution of breastfeeding duration has a mean of 5.7 months and a median of two months. Important determinants of breastfeeding duration include maternal age, ethnicity, period of first birth, husband's occupation and work status of the woman.

Fulltext Trauma induced testicular torsion: a reminder for the unwary

Yeap JS, Moissinac K

J Accid Emerg Med, 2000 Sep;17(5):381-2.
PMID: 11005420

Trauma induced testicular torsion is a well recognised entity, the incidence being 4-8% in most studies reporting on testicular torsion. The signs and symptoms of testicular torsion may easily be mistakenly attributed to preceding testicular trauma if there was such an event. A patient is described with trauma induced testicular torsion who presented on three occasions before a decision was made to perform scrotal exploration. Unfortunately, an orchidectomy was the outcome. The message that trauma can and not infrequently does precipitate torsion, needs to be reiterated. Awareness of the entity and constant vigilance is required of clinicians to avoid a delay in definitive treatment.

Fulltext Decompression illness associated with underwater logging: 6 case reports from Kenyir Lake, Malaysia

Loke YK, Tee MH, Tan MH

Med J Malaysia, 1998 Mar;53(1):100-3.
PMID: 10968146

The formation of Kenyir Lake as part of a hydroelectric project in the 1980s caused much forest area to be submerged. From 1991, underwater divers were employed to log these sunken trees at depths of up to 100 meters. At least 6 mishaps involving underwater logging personnel were recorded from March 1994 to August 1996. We retrospectively reviewed 5 cases who were managed in Hospital Kuala Terengganu. The patients presented with marked cardiorespiratory and neurological disturbances. One diver died in the Hospital while another died at the recompression chamber. Three divers were treated with recompression and improved. Average delay before the start of recompression was 14 hours. Underwater logging has definite dangers and steps must be taken to ensure that both the divers and the equipment are appropriate for the task. Availability of a nearby recompression facility would greatly enhance the management of diving accidents, not only for commercial divers but also for recreational divers who frequent the islands nearby.

Sexually transmitted infections in Singapore teenagers

Chan RK, Tan HH

Ann Acad Med Singap, 2003 Jan;32(1):25-8.
PMID: 12625094

INTRODUCTION: This is a review of sexual knowledge, behaviour and the extent of sexually transmitted infections (STI), including human immunodeficiency virus (HIV) infection, in Singapore adolescents.
METHODS: Data were retrieved from relevant studies, reports and statistics concerning STI and HIV in Singapore.
RESULTS: For many reasons, adolescents are at a higher risk of acquiring STI and HIV infections. Adolescents in Singapore are still relatively conservative in their sexual attitudes and behaviour. Most of those who had sex never used condoms. Fortunately, the incidence of STI and HIV infections among adolescents is relatively low. However, this may be changing, and there is a proportion of individuals who exhibit higher risk behaviours.
CONCLUSIONS: In this age of rapidly changing morals and values, accurate information and skills need to be provided to young people to ensure that they are adequately prepared to protect themselves from acquiring STI/HIV infection.

Fulltext Selective thoracic fusion of King II scoliosis with segmental spinal instrumentation

Lim HH, Choon DSK

Med J Malaysia, 2000 Sep;55 Suppl C:29-34.
PMID: 11200041

Segmental spinal instrumentation with Harrington rod secured to the spine by sublaminar wires was a popular method of scoliosis correction in 1980's. It was gradually replaced by newer rod-hook systems due to concern about neurological complications. However, correction of type II and III curves by selectively fusing the thoracic curves with these new instruments has resulted in poor results in some cases. The aim of this study is to review the result of selective thoracic fusion treated by segmental spinal instrumentation. Between January 1989 to October 1994, 31 patients with King II scoliosis were treated operatively in our unit. These consisted of 29 girls and 2 boys. The mean age of these patients were 11.3 years. The study population consisted of 21 Chinese, 5 Malays and 5 Indians. In one patient, the thoracic curve was convex to the left whilst the thoracic curves in the majority were to the right. The surgery was performed by three surgeons using harrington rods and posterior fusion with autograft. Anterior releases were also required in eight patients to increase flexibility. The curve correction obtained was an improvement from a average preoperative cobb's angle of 71.5 degrees to 39.5 degrees postoperatively. After an average follow-up period of 77.9 months, the correction deteriorated by 22% in the thoracic curve and 59% in the lumbar spine without disturbance to truncal balance. Only one sublaminar wire broke. However, no implant failure or removal has to be performed as yet. This technique appears useful in our institution with minimal morbidity.

The prevalence of recurrent abdominal pain in 11- to 16-year-old Malaysian schoolchildren

Boey C, Yap S, Goh KL

J Paediatr Child Health, 2000 Apr;36(2):114-6.
PMID: 10760006

OBJECTIVE: To determine the prevalence of recurrent abdominal pain (RAP) among Malaysian school children aged from 11 to 16 years.
METHODOLOGY: A preliminary cross-sectional survey in which three urban schools and three rural schools were selected randomly. Two classes were selected randomly from each year. A questionnaire was given to each child asking him or her about whether they had experienced abdominal pain occurring at least three times over a period of at least 3 months, interfering with normal daily activity. 1 Interfering with normal daily activity was defined as missing school and/or having to stop doing a routine daily activity on account of the pain. Girls whose pains were related to periods were excluded. After the forms had been completed, each child was again interviewed to ensure that Apley's criteria1 was fulfilled in cases of RAP.
RESULTS: The overall prevalence of RAP among 1549 schoolchildren (764 boys; 785 girls) was 10.2% (95% confidence interval (CI), 8.8-11.8). There appeared to be a higher prevalence in rural schoolchildren (P = 0.008; odds ratio (OR) 1.58), in those with a lower family income (P < 0.001; OR 2.02) and in children whose fathers have a lower educational attainment (P = 0.002; OR 1. 92). There were no significant differences in the prevalence of RAP among children of different sex, age, ethnic group and family size.
CONCLUSION: : In spite of differences in time and culture, the overall prevalence of 10.2% found in this study is similar to that determined by Apley.1 There are significant differences in the prevalence of RAP between children from rural and urban schools, among children with different family incomes and among children whose parents have different educational backgrounds.

Fulltext Accident characteristics of injured motorcyclists in Malaysia

Pang TY, Radin Umar RS, Azhar AA, Ahmad MM, Nasir MTM, Harwant S

Med J Malaysia, 2000 Mar;55(1):45-50.
PMID: 11072490 MyJurnal

This study examines the accident characteristics of injured motorcyclists in Malaysia. The aim of this study is to identify the characteristics of motorcyclists who are at higher fatality risk and subsequently be the targeted group for the fatality-reduction countermeasures. A total of 412 motorcycle crash victims with serious or fatal injuries were analysed. The results showed that the injured motorcyclists were predominant young, novice riders of less than 3 years licensure and male. A fatal outcome was more likely to be associated with a larger engine capacity motorcycle, collision with a heavy vehicle, head on collision, and collision at a non-junction road. In contrast, a non-fatal outcome was more likely to be associated with a small engine capacity motorcycle, collision with another motorcycle or passenger car, junction accidents, and side or rear collisions.

Undercorrection of myopia enhances rather than inhibits myopia progression

Chung K, Mohidin N, O'Leary DJ

Vision Res, 2002 Oct;42(22):2555-9.
PMID: 12445849

The effect of myopic defocus on myopia progression was assessed in a two-year prospective study on 94 myopes aged 9-14 years, randomly allocated to an undercorrected group or a fully corrected control group. The 47 experimental subjects were blurred by approximately +0.75 D (blurring VA to 6/12), while the controls were fully corrected. Undercorrection produced more rapid myopia progression and axial elongation (ANOVA, F(1,374)=14.32, p<0.01). Contrary to animal studies, myopic defocus speeds up myopia development in already myopic humans. Myopia could be caused by a failure to detect the direction of defocus rather than by a mechanism exhibiting a zero-point error.

Fulltext Providing a cure for beta thalassaemia major

Chan LL, Lin HP, Ariffin WA, Ariffin H

Med J Malaysia, 2001 Dec;56(4):435-40.
PMID: 12014762

The current treatment options for beta thalassaemia major patients include conservative treatment with blood cell transfusions and iron chelation or stem cell transplantation. Regular blood transfusions inevitably lead to multi-organ haemosiderosis and are attended by risks of blood-borne infections. Results from stem cell transplantation are good and suggest that this should be offered as first line therapy when a matched sibling donor is available because the patient is often cured and able to live a normal life. Of 38 Malaysian children who underwent bone marrow or cord blood transplantations using matched sibling donors, 29 (76%) are now cured.

Change in endotracheal tube cuff pressure during nitrous oxide anaesthesia: a comparison between air and distilled water cuff inflation

Ahmad NL, Norsidah AM

Anaesth Intensive Care, 2001 Oct;29(5):510-4.
PMID: 11669433

In this prospective, randomized controlled trial, changes in endotracheal tube cuff pressure were studied in 60 patients undergoing elective surgery under general anaesthesia with nitrous oxide and oxygen. The cuffs were inflated with either air or distilled water. The mean pressure in the air-filled cuffs increased steadily throughout the procedure, reaching 47.5 +/- 7.3 cmH2O at one hour compared with 31.6 +/- 2.4 cmH2O mean pressure in the water-filled cuffs. The pressure and the rate of rise in cuff pressure were significantly lower (P<0.05) in the water-filled cuffs throughout the hour of study. When an endotracheal tube cuff is distended with water, the rise in cuff pressure during nitrous oxide anaesthesia is lower than that of an air-filled cuff.
