    PMID: 6324601
    We studied 1,629 febrile patients from a rural area of Malaysia, and made a laboratory diagnosis in 1,025 (62.9%) cases. Scrub typhus was the most frequent diagnosis (19.3% of all illnesses) followed by typhoid and paratyphoid (7.4%); flavivirus infection (7.0%); leptospirosis (6.8%); and malaria (6.2%). The hospital mortality was very low (0.5% of all febrile patients). The high prevalence of scrub typhus in oil palm laborers (46.8% of all febrile illnesses in that group) was confirmed. In rural Malaysia, therapy with chloramphenicol or a tetracycline would be appropriate for undiagnosed patients in whom malaria has been excluded. Failure to respond to tetracycline within 48 hours would usually suggest a diagnosis of typhoid, and indicate the need for a change in therapy.

  2. Leptospirosis in Malaysia: a common cause of short-term fever
    Brown GW, Lee CK, Huxsoll DL, Ng TS, Lim KJ, Wan HS, et al.
    Southeast Asian J. Trop. Med. Public Health, 1976 Sep;7(3):380-3.
    PMID: 1030842
    A study of 1,437 unselected febrile patients in rural Malaysia yielded a diagnosis of leptospirosis in 86 (6.0%). The clinical syndrome was mild to moderate in all cases, jaundice was observed in only 2 (2.3%) and no deaths were documented. The diagnosis was not clinically obvious in most cases, and it is apparent that many infections must be going unnoticed at present.

    Bone and joint tuberculosis is a serious medical problem; tuberculosis of sternoclavicular joint is rare. We present a case of a healthy 37-year old man with sternoclavicular joint tuberculosis. The subject presented with a three weeks history of left sternoclavicular joint painless swelling without fever or weight loss. He had no previous history of pulmonary tuberculosis. Laboratory testing revealed erythrocyte sedimentation rate of 70 mm/hour, C-reactive protein of 30 mg/liter and a normal leucocyte count. Biopsy of the lesion showed caseous necrosis and pus culture revealed Mycobacterium tuberculosis. He was treated with joint debridement and anti-tuberculous medications. Tuberculosis resolved completely but post-infection patients had residual joint arthritis. Tuberculosis may infect unusual joints such as the sternoclavicular joint.

    Common causes of acute febrile illness in tropical countries have similar symptoms, which often mimic those of dengue. Accurate clinical diagnosis can be difficult without laboratory confirmation and disease burden is generally under-reported. Accurate, population-based, laboratory-confirmed incidence data on dengue and other causes of acute fever in dengue-endemic Asian countries are needed.

  7. Notes from the field: acute muscular sarcocystosis among returning travelers - Tioman Island, Malaysia, 2011
    Centers for Disease Control and Prevention (CDC)
    MMWR Morb Mortal Wkly Rep, 2012 Jan 20;61(2):37-8.
    PMID: 22258418
    GeoSentinel (the surveillance program of the International Society of Travel Medicine and CDC) has identified 32 cases of suspected acute muscular sarcocystosis in travelers returning from Tioman Island off the east coast of peninsular Malaysia. All the patients traveled to Tioman Island during the summer of 2011. Within days or weeks of returning home, all experienced fever and muscle pain, often severe and prolonged. All had peripheral eosinophilia, and most had elevated serum creatinine phosphokinase levels. Most were tested for acute trichinosis and toxoplasmosis by serology, and all of these tests were negative. Approximately half of the patients were identified in Germany; others were reported elsewhere in Europe, and in North America and Asia. Muscle biopsy from two patients demonstrated organisms consistent with sarcocystosis, one from a group of five ill travelers and one from a group of three.

  8. Update: outbreak of Nipah virus--Malaysia and Singapore, 1999
    Centers for Disease Control and Prevention (CDC)
    MMWR Morb Mortal Wkly Rep, 1999 Apr 30;48(16):335-7.
    PMID: 10366143
    During March 1999, health officials in Malaysia and Singapore, in collaboration with Australian researchers and CDC, investigated reports of febrile encephalitic and respiratory illnesses among workers who had exposure to pigs. A previously unrecognized paramyxovirus (formerly known as Hendra-like virus), now called Nipah virus, was implicated by laboratory testing in many of these cases. Febrile encephalitis continues to be reported in Malaysia but has decreased coincident with mass culling of pigs in outbreak areas. No new cases of febrile illness associated with Nipah virus infection have been identified in Singapore since March 19, 1999, when abattoirs were closed. This report summarizes interim findings from ongoing epidemiologic and laboratory investigations in Malaysia and Singapore.

  9. Fulltext Deaths of children during an outbreak of hand, foot, and mouth disease in Sarawak, Malaysia: clinical and pathological characteristics of the disease. For the Outbreak Study Group
    Chan LG, Parashar UD, Lye MS, Ong FG, Zaki SR, Alexander JP, et al.
    Clin Infect Dis, 2000 Sep;31(3):678-83.
    PMID: 11017815
    From April through June 1997, 29 previously healthy children aged <6 years (median, 1.5 years) in Sarawak, Malaysia, died of rapidly progressive cardiorespiratory failure during an outbreak of hand, foot, and mouth disease caused primarily by enterovirus 71 (EV71). The case children were hospitalized after a short illness (median duration, 2 days) that usually included fever (in 100% of case children), oral ulcers (66%), and extremity rashes (62%). The illness rapidly progressed to include seizures (28%), flaccid limb weakness (17%), or cardiopulmonary symptoms (of 24 children, 17 had chest radiographs showing pulmonary edema, and 24 had echocardiograms showing left ventricular dysfunction), resulting in cardiopulmonary arrest soon after hospitalization (median time, 9 h). Cardiac tissue from 10 patients showed normal myocardium, but central nervous system tissue from 5 patients showed inflammatory changes. Brain-stem specimens from 2 patients were available, and both specimens showed extensive neuronal degeneration, inflammation, and necrosis, suggesting that a central nervous system infection was responsible for the disease, with the cardiopulmonary dysfunction being neurogenic in origin. EV71 and possibly an adenovirus, other enteroviruses, or unknown cofactors are likely responsible for this rapidly fatal disease.

    PMID: 2895603
    Haemorrhagic fever with renal syndrome (HFRS) is caused by a group of RNA viruses within the family of Bunyaviridae known as hantaviruses. The classical, severe form of HFRS is characterized by fever, headache, abdominal and lumbar pain, proteinuria, haemorrhagic phenomena, shock and renal failure. The disease is associated with the prototype Hantaan virus and occurs in rural areas of Korea and China with Apodemus mice as reservoir hosts. A clinically less severe form of HFRS, which is caused by Seoul virus, occurs in urban areas with the house rat Rattus novegicus as the main reservoir host. The disease in nonendemic areas may be atypical and patients with symptoms the hepatitis and minimal renal involvement have been observed in Malaysia. Outbreaks of HFRS in humans involving infected laboratory rat colonies have occurred in several medical centres in various countries. Hantaviruses cause a chronic, asymptomatic infection in rodents which excrete the virus in their lungs, saliva and urine. Man becomes infected mainly by inhalation of infected droplets from healthy rodent carriers. Seroepidemiological studies using mainly the indirect immunoflourescent antibody test of sera from humans and rats showed that hantaviruses have a worldwide distribution.

  11. Haemorrhagic fever with renal syndrome involving the liver
    Chan YC, Wong TW, Yap EH, Tan HC, Lee HW, Chu YK, et al.
    Med J Aust, 1987 Sep 07;147(5):248-9.
    PMID: 2890086
    A case of haemorrhagic fever with renal syndrome that originated in Malaysia is reported. The patient presented with clinical symptoms which were not typical of the disease as seen in endemic regions. Renal involvement, which is characteristic of haemorrhagic fever with renal syndrome, was mild, and the predominant symptom was a persistently marked elevation of serum transaminase levels that was suggestive of hepatitis. Liver involvement has not been described in the Asian form of haemorrhagic fever with renal syndrome. The patient developed a petechial skin rash and had severe thrombocytopenia. Serological confirmation of the diagnosis of haemorrhagic fever with renal syndrome was obtained by the demonstration of significant antibody rises to hantaviruses in the patient's acute- and convalescent-phase sera.

  12. Fulltext Effects of growing-up milk supplemented with prebiotics and LCPUFAs on infections in young children
    Chatchatee P, Lee WS, Carrilho E, Kosuwon P, Simakachorn N, Yavuz Y, et al.
    J Pediatr Gastroenterol Nutr, 2014 Apr;58(4):428-37.
    PMID: 24614142 DOI: 10.1097/MPG.0000000000000252
    OBJECTIVE: The aim of this study was to investigate the effect of growing-up milk (GUM) with added short-chain galacto-oligosaccharides (scGOS)/long-chain fructo-oligosaccharides (lcFOS) (9:1) (Immunofortis) and n-3 long-chain polyunsaturated fatty acids (LCPUFAs) on the occurrence of infections in healthy children attending day care centres.

    METHODS: In a randomised double-blind controlled, parallel, multicountry intervention study, 767 healthy children, ages 11 to 29 months, received GUM with scGOS/lcFOS/LCPUFAs (the active group, n = 388), GUM without scGOS/lcFOS/LCPUFAs (the control group, n = 379), or cow's milk (n = 37) for 52 weeks. The primary outcome measure was the number of episodes of upper respiratory tract infections or gastrointestinal infections based on a combination of subject's illness symptoms reported by the parents during the intervention period.

    RESULTS: Children in the active group compared with the control group had a decreased risk of developing at least 1 infection (299/388 [77%] vs 313/379 [83%], respectively, relative risk 0.93, 95% confidence interval [CI] 0.87-1.00; logistic regression P = 0.03). There was a trend toward a reduction (P = 0.07) in the total number of infections in the active group, which was significant when confirmed by one of the investigators (268/388 [69%] vs 293/379 [77%], respectively, relative risk 0.89, 95% CI 0.82-0.97; P = 0.004, post hoc). More infectious episodes were observed in the cow's milk group, when compared with both GUM groups (34/37 [92%] vs 612/767 [80%], respectively, relative risk 1.15, 95% CI 1.04-1.28).

    CONCLUSIONS: This is the first study in children to show a reduced risk of infection following consumption of GUM supplemented with scGOS/lcFOS/n-3 LCPUFAs. The borderline statistical significance justifies a new study to confirm this finding.

  13. Fulltext Politics of disease control in Africa and the critical role of global health diplomacy: A systematic review
    Chattu VK, Knight WA, Adisesh A, Yaya S, Reddy KS, Di Ruggiero E, et al.
    Health Promot Perspect, 2021;11(1):20-31.
    PMID: 33758752 DOI: 10.34172/hpp.2021.04
    Background: Africa is facing the triple burden of communicable diseases, non-communicable diseases (NCDs), and nutritional disorders. Multilateral institutions, bilateral arrangements, and philanthropies have historically privileged economic development over health concerns. That focus has resulted in weak health systems and inadequate preparedness when there are outbreaks of diseases. This review aims to understand the politics of disease control in Africa and global health diplomacy's (GHD's) critical role. Methods: A literature review was done in Medline/PubMed, Web of Science, Scopus, Embase, and Google scholar search engines. Keywords included MeSH and common terms related to the topics: "Politics," "disease control," "epidemics/ endemics," and "global health diplomacy" in the "African" context. The resources also included reports of World Health Organization, United Nations and resolutions of the World Health Assembly (WHA). Results: African countries continue to struggle in their attempts to build health systems for disease control that are robust enough to tackle the frequent epidemics that plague the continent. The politics of disease control requires the crafting of cooperative partnerships to accommodate the divergent interests of multiple actors. Recent outbreaks of COVID-19 and Ebola had a significant impact on African economies. It is extremely important to prioritize health in the African development agendas. The African Union (AU) should leverage the momentum of the rise of GHD to (i) navigate the politics of global health governance in an interconnected world(ii) develop robust preparedness and disease response strategies to tackle emerging and reemerging disease epidemics in the region (iii) address the linkages between health and broader human security issues driven by climate change-induced food, water, and other insecurities (iv) mobilize resources and capacities to train health officials in the craft of diplomacy. Conclusion: The AU, Regional Economic Communities (RECs), and African Centres for Disease Control should harmonize their plans and strategies and align them towards a common goal that integrates health in African development agendas. The AU must innovatively harness the practice and tools of GHD towards developing the necessary partnerships with relevant actors in the global health arena to achieve the health targets of the Sustainable Development Goals.

    Ebola virus disease (EVD) is an emerging and remerging zoonosis associated with high fatality rate, mainly caused by the Zaire Ebola virus (ZEBOV) and Sudan Ebola virus (SEBOV) strains. Approximately 20 epidemics of EVD have been documented mainly in Central African countries since 1976. Currently, there are no therapeutics agents and vaccines yet approved for EVD. However, several promising therapeutics and vaccines candidates are actively undergoing various phase of clinical development. This study aims to study the EVD dynamics and evaluate the potential impacts of vaccines and other preventive measures on EVD transmission control and significance of medical intervention on outcome of the disease. An initial branch chain model of EVD dynamics was built based on data obtained from previous study. Different epidemiological scenarios for EVD with impacts of intervention were simulated using Berkeley-Madonna Version 8.3.18 software. Every reduction in the exposure rate of EBV infection by 10% produces two- to five-fold improvement in protection against EVD. Transmission control is optimum when the rate of exposure to EBV infection is reduced below 1%. Optimal control of EVD transmission can be achieved through strategic implementation of successful vaccination programme, and other preventive measures as well as rapid delivery of supportive medical care.

  15. Fulltext A review of dengue research in Malaysia
    Cheah WK, Ng KS, Marzilawati AR, Lum LC
    Med J Malaysia, 2014 Aug;69 Suppl A:59-67.
    PMID: 25417953 MyJurnal
    Dengue infection is a major cause of morbidity and mortality in Malaysia. To date, much research on dengue infection conducted in Malaysia have been published. One hundred and sixty six articles related to dengue in Malaysia were found from a search through a database dedicated to indexing all original data relevant to medicine published between the years 2000-2013. Ninety articles with clinical relevance and future research implications were selected and reviewed. These papers showed evidence of an exponential increase in the disease epidemic and a varying pattern of prevalent dengue serotypes at different times. The early febrile phase of dengue infection consist of an undifferentiated fever. Clinical suspicion and ability to identify patients at risk of severe dengue infection is important. Treatment of dengue infection involves judicious use of volume expander and supportive care. Potential future research areas are discussed to narrow our current knowledge gaps on dengue infection.

    Autoinflammatory disorders are characterized by dysregulated innate immune response, resulting in recurrent uncontrolled systemic inflammation and fever. Gain-of-function mutations in NLRC4 have been described to cause a range of autoinflammatory disorders. We report a twelve-year-old Malay girl with recurrent fever, skin erythema, and inflammatory arthritis. Whole exome sequencing and subsequent bidirectional Sanger sequencing identified a heterozygous missense mutation in NLRC4 (NM_001199138: c.1970A > T). This variant was predicted to be damaging in silico, was absent in public and local databases and occurred in a highly conserved residue in the leucine-rich repeat (LRR) domain. Cytokine analysis showed extremely high serum IL-18 and IL-18/CXCL9 ratio, consistent with other NLRC4-MAS patients. In summary, we identified the first patient with a novel de novo heterozygous NLRC4 gene mutation contributing to autoinflammatory disease in Malaysia. Our findings reinforce the likely pathogenicity of specific LRR domain mutations in NLRC4 and expand the clinical spectrum of NLRC4 mutations.

    PMID: 21265245 MyJurnal
    Malaysia experienced the first outbreak of chikungunya (CHIK) in Klang in late 1998 due to CHIK virus of Asian genotype. The CHIK virus of Asian genotype reemerged causing outbreak in Bangan Panchor, Perak in March 2006. CHIK virus of Central/East African genotype was first detected from a patient who returned from India in August 2006. In December 2006, CHIK virus of Central/East African genotype was re-introduced into Malaysia from India and caused an outbreak in Kinta district, Perak but was successfully controlled following an early detection and institution of intensive vector control measures. In late April 2008, CHIK virus of Central/East African genotype was laboratory confirmed as the cause of CHIK outbreak in Johore which spread to other parts of Malaysia by August 2008. Phylogenetic analysis based on the 254-bp fragment of the virus envelope protein gene as the genetic marker showed that three different strains of CHIK virus of Central/East African genotype were introduced into Malaysia on three separate occasions from 2006 to 2008. The strain that was introduced into Johor state was responsible for its subsequent spread to other parts of Malaysia, inclusive of Sarawak.

    Strongyloides stercoralis is an intestinal nematode which is endemic in tropical and subtropical countries. The global prevalence of Strongyloides is unknown. Strongyloidiasis is found more frequently in the socioeconomically disadvantaged, in institutionalized populations, and in rural areas. The spectrum of disease varies. It may cause asymptomatic infection, mild eosinophilia or hyperinfection syndrome in the most severe form. Here we reported a case of Strongyloides hyperinfection syndrome in an immunosuppressed patient. This patient is a 54-year-old man with myasthenia gravis on long term azathioprine and prednisolone. He presented with fever associated with diarrhoea and was in septic shock. His blood culture was positive forKlebsiella pneumoniae.Strongyloides stercoralis larvae were detected in his sputum and stool sample. He was diagnosed to have Strongyloides hyperinfection and was treated with subcutaneous ivermectin. He recovered well. Our case demonstrated the association of Strongyloideshyperinfection with superimposed gram-negative sepsis as a consequence of prolonged immunosuppression. A high index of suspicion is needed in approaching patient with risk factors of hyperinfection syndrome.

    PMID: 18935745 MyJurnal
    Typhoid fever being a systemic infection can present in a multitude of ways, involving various systems. Here we describe a case of typhoid fever presenting with acute cerebellar ataxia and marked thrombocytopenia. This atypical presentation is not common in typhoid fever and can lead to misdiagnosis as well as a delay in the initiation of appropriate therapy. Prompt clinical improvement and the return of platelet counts to normal were noted after the patient was started on IV Ceftriaxone.
