  1. Is There An Optimal Time for Performing Cranioplasties? Results from a Prospective Multinational Study
    Quah BL, Low HL, Wilson MH, Bimpis A, Nga VDW, Lwin S, et al.
    World Neurosurg, 2016 Oct;94:13-17.
    PMID: 27368511 DOI: 10.1016/j.wneu.2016.06.081
    BACKGROUND: The optimal timing of cranioplasty remains uncertain.

    OBJECTIVE: We hypothesized that the risk of infections after primary cranioplasty in adult patients who underwent craniectomies for non-infection-related indications are no different when performed early or delayed. We tested this hypothesis in a prospective, multicenter, cohort study.

    METHODS: Data were collected prospectively from 5 neurosurgical centers in the United Kingdom, Malaysia, Singapore, and Bangladesh. Only patients older than 16 years from the time of the non-infection-related craniectomy were included. The recruitment period was over 17 months, and postoperative follow-up was at least 6 months. Patient baseline characteristics, rate of infections, and incidence of hydrocephalus were collected.

    RESULTS: Seventy patients were included in this study. There were 25 patients in the early cranioplasty cohort (cranioplasty performed before 12 weeks) and 45 patients in the late cranioplasty cohort (cranioplasty performed after 12 weeks). The follow-up period ranged between 16 and 34 months (mean, 23 months). Baseline characteristics were largely similar but differed only in prophylactic antibiotics received (P = 0.28), and primary surgeon performing cranioplasty (P = 0.15). There were no infections in the early cranioplasty cohort, whereas 3 infections were recorded in the late cohort. This did not reach statistical significance (P = 0.55).

    CONCLUSIONS: Early cranioplasty in non-infection-related craniectomy is relatively safe. There does not appear to be an added advantage to delaying cranioplasties more than 12 weeks after the initial craniectomy in terms of infection reduction. There was no significant difference in infection rates or risk of hydrocephalus between the early and late cohorts.

  2. Changes in the prevalence of influenza-like illness and influenza vaccine uptake among Hajj pilgrims: A 10-year retrospective analysis of data
    Alfelali M, Barasheed O, Tashani M, Azeem MI, El Bashir H, Memish ZA, et al.
    Vaccine, 2015 May 21;33(22):2562-9.
    PMID: 25887084 DOI: 10.1016/j.vaccine.2015.04.006
    Influenza is an important health hazard among Hajj pilgrims. For the last ten years, pilgrims are being recommended to take influenza vaccine before attending Hajj. Vaccination coverage has increased in recent years, but whether there has been any change in the prevalence of influenza-like illness (ILI) is not known. In this analysis, we examined the changes in the rate of ILI against seasonal influenza vaccine uptake among Hajj pilgrims over the last decade.

  3. Fulltext COVID-19 vaccination campaign in Nepal, emerging UK variant and futuristic vaccination strategies to combat the ongoing pandemic
    Sah R, Khatiwada AP, Shrestha S, Bhuvan KC, Tiwari R, Mohapatra RK, et al.
    Travel Med Infect Dis, 2021;41:102037.
    PMID: 33781945 DOI: 10.1016/j.tmaid.2021.102037
    With the emergence of the new variants of concern (VOC) of the SARS-CoV-2, the efficacy of certain vaccines against them requires further research and considerations for future scenarios of COVID-19 vaccination. The vaccines' lack of efficacy against VOC will pose at risk to the vaccinated population and is a public health threat. In this commentary, we discuss Nepal's recent experiences and expectations regarding the confirmation of VOC B.1.1.7 from the United Kingdom in the country.

  4. Fulltext The systematic cultural adaptation of a UK public health cancer awareness raising programme for Malaysia: the Be Cancer Alert Campaign
    Schliemann D, Su TT, Paramasivam D, Somasundaram S, Ibrahim Tamin NSB, Dahlui M, et al.
    Transl Behav Med, 2019 11 25;9(6):1087-1099.
    PMID: 31583402 DOI: 10.1093/tbm/ibz134
    Increasingly, policy and research attention is being directed toward improving global health in low- and middle-income countries. This study investigated the cultural adaptation of a UK-designed and developed evidence-based mass media campaign with the aim of improving colorectal cancer and breast cancer awareness in Malaysia. Guided by the heuristic framework of cultural adaptation, a multidisciplinary team adapted the UK Be Cancer Aware programme for implementation in the Malaysian context. The approach included five steps: (a) information gathering and needs assessment; (b) preliminary design; (c) preliminary testing; (d) refinement; and (e) final trial. Key findings from the information gathering stage related to the need to take into account differences in ethnicity, religion, and beliefs about cancer. Discussions with experts indicated that particular words were not acceptable in Malay culture and that specific aspects were "taboo" (e.g., showing pictures of breasts in relation to breast cancer on TV). Stage 3 of the analysis revealed that the presentation of cancer survivors rather than health professionals on programme materials was preferred by Malaysians and that there was a poor level of awareness about colorectal cancer. The results were used systematically to adapt two culturally suitable cancer awareness mass media campaigns for implementation in Malaysia. The developed materials were in line with government priorities and took into account the local health care system structure. The establishment of a partnership with key stakeholders (e.g., the Ministry of Health and the lead patient advocacy organization) and the application of a systematic approach to address cultural factors and resource constraints contribute to the successful implementation of public health programmes in global health settings.

  6. A retrospective serological suvey of Royal Marines previously exposed to Pseudomonas pseudomallei in South East Asia
    Preston PJ, Lightfoot N, Clarke P
    Trans R Soc Trop Med Hyg, 1976;70(4):335-7.
    PMID: 1006764
    Following the suggestion that it was possible that cases of melioidosis amongst those who had been exposed abroad in the past, might be escaping notice, 487 Royal Marines were examined by indirect haemagglutination studies. Four hundred and eleven of these subjects had served for variable times in areas where melioidosis has been known to occur in Indonesia and Malaya, between 1960 and 1974, occupied in activities in the jungle and paddy fields during which exposure to the disease was to be expected. No evidence of residual subclinical melioidosis was found and it seems unlikely that recrudescent disease will prove to be a problem in the future for English servicemen who have been in South East Asia.

  7. Hugh Alistair Reid OBE MD: investigation and treatment of snake bite
    Hawgood BJ
    Toxicon, 1998 Mar;36(3):431-46.
    PMID: 9637363
    Alistair Reid was an outstanding clinician, epidemiologist and scientist. At the Penang General Hospital, Malaya, his careful observation of sea snake poisoning revealed that sea snake venoms were myotoxic in man leading to generalized rhabdomyolysis, and were not neurotoxic as observed in animals. In 1961, Reid founded and became the first Honorary Director of the Penang Institute of Snake and Venom Research. Effective treatment of sea snake poisoning required specific antivenom which was produced at the Commonwealth Serum Laboratories in Melbourne from Enhydrina schistosa venom supplied by the Institute. From the low frequency of envenoming following bites, Reid concluded that snakes on the defensive when biting man seldom injected much venom. He provided clinical guidelines to assess the degree of envenoming, and the correct dose of specific antivenom to be used in the treatment of snake bite in Malaya. Reid demonstrated that the non-clotting blood of patients bitten by the pit viper, Calloselasma rhodostoma [Ancistrodon rhodostoma] was due to venom-induced defibrination. From his clinical experience of these patients, Reid suggested that a defibrinating derivative of C. rhodostoma venom might have a useful role in the treatment of deep vein thrombosis. This led to Arvin (ancrod) being used clinically from 1968. After leaving Malaya in 1964, Alistair Reid joined the staff of the Liverpool School of Tropical Medicine, as Senior Lecturer. Enzyme-linked immunosorbent assay (ELISA) for detecting and quantifying snake venom and venom-antibody was developed at the Liverpool Venom Research Unit: this proved useful in the diagnosis of snake bite, in epidemiological studies of envenoming patterns, and in screening of antivenom potency. In 1977, Dr H. Alistair Reid became Head of the WHO Collaborative Centre for the Control of Antivenoms based at Liverpool.

  8. Engaging with Lyell: Alfred Russel Wallace's Sarawak Law and Ternate papers as reactions to Charles Lyell's Principles of Geology
    Costa JT
    Theory Biosci, 2013 Dec;132(4):225-37.
    PMID: 24014172 DOI: 10.1007/s12064-013-0188-1
    Alfred Russel Wallace (1823-1913) and Charles Darwin (1809-1882) are honored as the founders of modern evolutionary biology. Accordingly, much attention has focused on their relationship, from their independent development of the principle of natural selection to the receipt by Darwin of Wallace's essay from Ternate in the spring of 1858, and the subsequent reading of the Wallace and Darwin papers at the Linnean Society on 1 July 1858. In the events of 1858 Wallace and Darwin are typically seen as central players, with Darwin's friends Charles Lyell (1797-1875) and Joseph Dalton Hooker (1817-1911) playing supporting roles. This narrative has resulted in an under-appreciation of a more central role for Charles Lyell as both Wallace's inspiration and foil. The extensive anti-transmutation arguments in Lyell's landmark Principles of Geology were taken as the definitive statement on the subject. Wallace, in his quest to solve the mystery of species origins, engaged with Lyell's arguments in his private field notebooks in a way that is concordant with his engagement with Lyell in the 1855 and 1858 papers. I show that Lyell was the object of Wallace's Sarawak Law and Ternate papers through a consideration of the circumstances that led Wallace to send his Ternate paper to Darwin, together with an analysis of the material that Wallace drew upon from the Principles. In this view Darwin was, ironically, intended for a supporting role in mediating Wallace's attempted dialog with Lyell.

  9. The effects of exclusion of dietary egg and milk in the management of asthmatic children: a pilot study
    Yusoff NA, Hampton SM, Dickerson JW, Morgan JB
    J R Soc Promot Health, 2004 Mar;124(2):74-80.
    PMID: 15067979 DOI: 10.1177/146642400412400211
    Current understanding of the use of exclusion diets in the management of asthma in children is limited and controversial. The aim of this study was to examine the effects of excluding eggs and milk on the occurrence of symptoms in children with asthma and involved 22 children aged between three and 14 years clinically diagnosed as having mild to moderate disease. The investigation was single blind and prospective, and parents were given the option of volunteering to join the 'experiment' group, avoiding eggs, milk and their products for eight weeks, or the 'control' group, who consumed their customary food. Thirteen children were recruited to the experimental group and nine to the control group. A trained paediatrician at the beginning and end of the study period assessed the children. A seven-day assessment of food intake was made before, during and immediately after the period of dietary intervention in both groups. A blood sample was taken from each child for determination of food specific antibodies and in those children who could do so, the peak expiratory flow rate (PEFR) was measured. Based on the recommended nutrient intake (RNI), the mean percentage energy intake of the children in the experimental group was significantly lower (p < 0.05) in the experimental group. After the eight-week study period and compared with baseline values, the mean serum anti-ovalbumin IgG and anti-beta lactoglobulin IgG concentrations were statistically significantly reduced (p < 0.05) for both in the experimental group. In contrast, the values for anti-ovalbumin IgG in the control group were significantly increased and those for anti-beta lactoglobulin IgG were practically unchanged. The total IgE values were unchanged in both groups. Over the study period, the PEFR in those children in the experimental group able to perform the test was significantly increased, but no such change was noted in the children in the control group who could do the test. These results suggest that even over the short time period of eight weeks, an egg- and milk-free diet can reduce atopic symptoms and improve lung function in asthmatic children.

  10. An international view of surgically assisted conception and surrogacy tourism
    Ahmad N
    Med Leg J, 2011;79(Pt 4):135-45.
    PMID: 22156300 DOI: 10.1258/mlj.2011.011029
    Modern medicine, specifically assisted reproductive technology (ART), has overtaken the law in many jurisdictions around the world. New technologies and practices open a Pandora's Box of ethical, religious, social and legal questions, and may present a variety of significant legal problems to the courts and legislators. Surrogate motherhood and pregnancy through ART have both attracted controversy. Some groups condemn ART and want it banned while its supporters acknowledge there is a need for legislative guidelines and regulations. A proposed statute, the Assisted Reproductive Technique Services Act, aimed at regulating reproductive technologies, including surrogacy arrangements, will be introduced in the Malaysian parliament, probably in 2012, and the Assisted Reproductive Technology (Regulation) Bill 2010 is already before the Indian parliament. This paper will discuss several of the potential socio-legal issues surrounding ART in the light of the complex situation, with a comparative analysis of the Malaysian, USA, UK and Indian positions.

  11. Fulltext Changes in salivary immunoglobulin A (IgA) following match-play and training among English premiership footballers
    Fredericks S, Fitzgerald L, Shaw G, Holt DW
    Med J Malaysia, 2012 Apr;67(2):155-8.
    PMID: 22822634
    Decreased salivary immunoglobulin A (sIgA), a component of mucosal immunity, is associated with intensive physical activity: suggesting that sIgA may be used for the monitoring of mucosal immunity with footballers. We investigated changes in sIgA in elite footballers, in response to training and match-play. There was a decrease in sIgA following training, with a return to pre-training levels after 18 hours of rest. This return to resting levels was not observed following competitive match-play. Overnight rest was sufficient for mucosal IgA recovery following training but not following two successive matches, suggesting that sIgA may be used to monitor training in multi-sprint sports.

  12. Fulltext Kaposi's sarcoma: case report and treatment options
    Tan WC, Chan LC
    Med J Malaysia, 2011 Oct;66(4):383-4.
    PMID: 22299569
    Kaposi's sarcoma (KS) is strongly associated with Human Herpes Virus 8 (HHV8) and Human Immunodeficiency Virus infection (HIV). It was the first malignancy to be linked with Acquired Immunodeficiency Syndrome (AIDS). We report a case of Kaposi's sarcoma in a newly diagnosed retroviral homosexual patient with CD4 count of 21. He had multiple firm discrete violaceous plaques and nodules scattered over the face, scalp, hard palate, trunk and genitalia. Biopsy of a skin nodule over the trunk and a biopsy of a lesion from the gastric mucosa confirmed Kaposi's sarcoma. He was started on Highly Active Antiretroviral Therapy (HAART) and cryotherapy (liquid nitrogen) was given for the lesions over the skin. He responded well to treatment. Liquid nitrogen is a useful adjuvant treatment for Kaposi's sarcoma.

  13. Fulltext The impact of luteal supplement on pregnancy outcome following stimulated IVF cycles
    Tay PYS, Lenton EA
    Med J Malaysia, 2005 Jun;60(2):151-7.
    PMID: 16114155
    This is a prospeve randomised study designed to clarify the impact of various luteal support regimes (HCG and progesterone) on progesterone profiles and pregnancy outcomes. This study involved subjects undergone down regulated. stimulated IVF cycles using various types of luteal support, namely: Cyclogest (n=35). Crinone gel (n=36), various doses of Utrogestan (n=55) and HCG (n=35). Various doses of Utrogestan (administered vaginally), Crinone gel (progesterone administered vaginally) and Cyclogest (progesterone administered rectally) supplementation induced similar end plasma progesterone concentrations ranging from 26 to 32 mmnl/l. These progesterone regimes produced no significant differences. Hence, the impact of exogenous proge,terone supplement was relatively trivial and did not 'stabilise' the sub-optimal luteal phase. In contrast, two small HCG injections during the early and mid-luteal phase possessed a much greater ability to 'stabilise' progesterone profiles. Despite this additional advantage, implantation and pregnancy rates with either HCG or progesterone supplements were similar. Although none of these forms of luteal support adequately 'normalised' luteal progesterone profiles, this did not appear to be detrimental to the process of implantation.

    PMID: 14556352
    Historical perspective of terminations of unwanted pregnancies in the UK. Moral and ethical considerations imposed by established church's teachings becoming increasingly in conflict with the wishes and expectations of a more secular society. Recognition that illegal abortion was, as a matter of fact available, at great risk to vulnerable girls and women. Eventually public demand and a radical and reforming government led to the current Statutory Framework. Statutory provisions: Offences against the Person Act 1861, Sections 58 and 59; Infant Life Preservation Act 1929 Section 1. Recognition of the limited flexibility allowed by the law in the original restrictive statutory framework. The direction to the jury in July 1938 by Macnaghten J in the case of R. v. Bourne [1939] 1 KB 687, where an eminent obstetrician was acquitted after carrying out an abortion on a young rape victim. Then the modern statutory provisions: Abortion Act 1967, amended by the Human Fertilisation and Embryology Act 1990. The statutory framework provides for healthcare professionals not to have to take part in terminations if they have a conscientious objection to doing so. While there are still fierce challenges from moral pressure groups when any changes in the detail of the law are proposed--such as reducing the maximum gestation period for a lawful termination--as a whole society seems to have accepted the current law. Issues affecting doctors who consider and provide terminations; current medico-legal problems relating to wanted pregnancies that have been lost by reason of clinical negligence, and unwanted children that have been born by reason of clinical negligence.

    PMID: 7845283
    Post Traumatic Stress Disorder (PTSD) is still a diagnosis which is frequently missed even by psychiatric professionals. Each doctor needs to maintain a high level of awareness that patients may have experienced trauma; that PTSD can often occur for a variety of common symptoms; and that it may also be at the root of a persisting treatment-resistant depressive or anxiety state. This case demonstrates that occupational accidents may result in this condition.

  17. Fulltext A clinical trial of tissue adhesive (histoacryl) in skin closure of groin wounds
    Teoh MK, Bucknall TE
    Med J Malaysia, 1989 Jun;44(2):122-8.
    PMID: 2696870
    The use of tissue adhesives has been widely studied since the 1960s. Since then they have found use in specialties like plastic surgery, neurosurgery, ENT surgery and dental surgery. Several papers have reported their safe use, both clinically and experimentally, particularly of the newer homologue n-butyl/2-cyanoacrylate (Histoacryl). In this study 43 patients (46 wounds) whose operations involved a groin incision were randomised into two groups for skin closure either with Dexon subcuticular suture (23 wounds) or Histoacryl glue (23 wounds). We found that both sets of wounds healed well with no wound infections or excessive inflammation when assessed at one week and four weeks. However the glued wounds had consistently better cosmesis scores (mean score 4.71 at four weeks) compared to the subcuticular Dexon wounds (mean score 4.00 at four weeks) and P value of less than 0.05. We feel that there is a place for tissue adhesives in skin closure for some general surgical wounds.

  18. Fulltext Recurrent gall-stone ileus: a case report
    Baruah DR
    Med J Malaysia, 1983 Sep;38(3):228-31.
    PMID: 6672566
    Gall stone is responsible for about 1% of total small bowel obstruction, 1.2 and recurrent gall stone ileus is even more unusual. 3 Gall stone ileus is caused by the impaction of the stone in bowel lumen. It was first described in a patient examined at autopsy by Bartholin in 1654. This paper based on unusual recurrent intestinal obstructions by a gall stone. The patient presented with large bowel obstruction and it was due to a large gall stone impacted in the pelvic colon. Four months later the same patient presented with small bowel obstruction due to large gall stone impacted in the terminal part of the ileum at 61 cms from the ileo-caecal valve. Gall stone obstruction of the colon is one of the rare complications. This rare complication usually occurs in elderly females' in whom there is frequently an underlying pathological condition at the site of obstruction in the colon. The calculus usually migrates through a cholecysto-colonic fistula in case of large bowel obstruction. In case of a small bowel obstruction the calculus usually migrates through a cholecysto-duodenal fistula. Diagnosis can be established by plain X-rays of the abdomen where there is gas shadow in the biliary system, sometimes the gall stone can be seen if it is radio opague (10-16% gall stone is radio opaque) at the site of obstruction. Otherwise diagnosis is always
    made at laparotomy.
