    PMID: 6822730
    The pattern of phage types of 2553 strains of Salmonella typhi isolated over the 10-year period 1970-9 was studied. During the period 29 different phage types were encountered, not including the categories of 'untypable strains', 'degraded Vi-strains' and Vi negative strains. For the period as a whole, the commonest phage types encountered were A (20.9%), E1 (14.8%), D1 (10.3%), degraded Vi positive strains (10.3%), untypable Vi strains (7.3%), C4 (7.1%), D2 (4.4%), E2 (3.9%) and type 25 (2.6%). There were phage types which appeared in the early years of the period and then disappeared (types B2, D9 and D1-N). Others only made their appearance in recent years (K1 and 53). Notable differences were also seen in the predilection of some phage types for certain geographical areas.

    PMID: 14750386
    A patient with ocular syphilis is presented. She experienced deterioration in vision following the commencement of treatment due to a Jarisch-Herxheimer reaction. This is a transient febrile illness that can occur in patients after the first adequate dose of an anti-microbial drug to treat infectious diseases such as syphilis, Lyme disease and relapsing fever. However, a Jarisch-Herxheimer reaction occurring in a patient receiving treatment for ocular syphilis can be serious, resulting in the rapid loss of vision.

  5. Improving typhoid management: An example of clinical audit
    Jackson AA
    Family Physician, 1994;6:4-6.
    Audit has improved certain aspects of management of typhoid fever detected through Klinik Perubatan Masyarakat at Hospital Universiti Sains Malaysia. We audited records of clinic patients who were blood culture positive for Salmonella typhi. For August to October 1992, we found 10 out of 31 cases (32%) were not admitted. Some of these were patients who defaulted, while some were managed as outpatients but not notified. We took action to educate the medical officers. For November 1992 - March 1993 we found 8 out of 24 cases (33%) were not admitted. Although the admission rate was no better, there was a non significant improvement in rate of notification by doctors. Defaulters were now the main problem, and so we took action to improve their follow-up, by using the clinic staff nurse. For April - August 1993, only 1 out of 16 cases (6%) was not admitted. This was a significant improvement (p=0.03)

  6. Fulltext Laboratory Diagnosis of Paratyphoid Fever: Opportunity of Surface Plasmon Resonance
    Alhaj-Qasem DM, Al-Hatamleh MAI, Irekeola AA, Khalid MF, Mohamud R, Ismail A, et al.
    Diagnostics (Basel), 2020 Jun 28;10(7).
    PMID: 32605310 DOI: 10.3390/diagnostics10070438
    Paratyphoid fever is caused by the bacterium Salmonellaenterica serovar Paratyphi (A, B and C), and contributes significantly to global disease burden. One of the major challenges in the diagnosis of paratyphoid fever is the lack of a proper gold standard. Given the absence of a licensed vaccine against S. Paratyphi, this diagnostic gap leads to inappropriate antibiotics use, thus, enhancing antimicrobial resistance. In addition, the symptoms of paratyphoid overlap with other infections, including the closely related typhoid fever. Since the development and utilization of a standard, sensitive, and accurate diagnostic method is essential in controlling any disease, this review discusses a new promising approach to aid the diagnosis of paratyphoid fever. This advocated approach is based on the use of surface plasmon resonance (SPR) biosensor and DNA probes to detect specific nucleic acid sequences of S. Paratyphi. We believe that this SPR-based genoassay can be a potent alternative to the current conventional diagnostic methods, and could become a rapid diagnostic tool for paratyphoid fever.

    PMID: 33597454
    Time series modelling and forecasting plays an important role in various domains. The objective of this paper is to construct a simple average ensemble method to forecast the number of cases for infectious diseases like dengue and typhoid and compare it by applying models for forecasting. In this paper we have also evaluated the correlation between the number of typhoid and dengue cases with the ecological variables. The monthly data of dengue and typhoid cases from 2014 to 2017 were taken from integrated diseases surveillance programme, Government of India. This data was analysed by three models namely support vector regression, neural network and linear regression. The proposed simple average ensemble model was constructed by ensemble of three applied regression models i.e. SVR, NN and LR. We combine the regression models based upon the error metrics such as Mean Square Error, Root Mean Square Error and Mean Absolute Error. It was found that proposed ensemble method performed better in terms of forecast measures. The finding demonstrates that the proposed model outperforms as compared to already available applied models on the basis of forecast accuracy.

  10. Incomplete Kawasaki Disease in a 44-day-old baby
    Nor Azizah A, Thong SP, Hung LC
    Med J Malaysia, 2018 08;73(4):257-259.
    PMID: 30121692 MyJurnal
    Kawasaki disease (KD) is an acute systemic vasculitis usually affecting children <5 years old. We report a 44-dayold baby who had persistent fever despite being on antibiotics for presumed sepsis. Erythema of Bacillus Calmette-Guerin (BCG) scar and thrombocytosis were noted on day-2 of illness. Diagnosis of incomplete KD was made on the 10th day of illness. Her fever resolved with intravenous immunoglobulin, but echocardiogram revealed coronary artery aneurysm. High index of suspicion is required to diagnose KD in infants ≤3 months since it is rare and commonly presents with incomplete clinical features. The presence of unexplained fever for ≥5 days with erythema of BCG scar or thrombocytosis in infants should alert the clinicians of KD.

  12. Fulltext Epidemiology and clinico-pathological characteristics of current goat pox outbreak in North Vietnam
    Pham TH, Lila MAM, Rahaman NYA, Lai HLT, Nguyen LT, Do KV, et al.
    BMC Vet Res, 2020 May 06;16(1):128.
    PMID: 32375821 DOI: 10.1186/s12917-020-02345-z
    BACKGROUND: In view of the current swine fever outbreak and the government aspiration to increase the goat population, a need arises to control and prevent outbreaks of goat pox. Despite North Vietnam facing sporadic cases of goat pox, this most recent outbreak had the highest recorded morbidity, mortality and case fatality rate. Thus, owing to the likelihood of a widespread recurrence of goat pox infection, an analysis of that outbreak was done based on selected signalment, management and disease pattern (signs and pathology) parameters. This includes examination of animals, inspection of facilities, tissue sampling and analysis for confirmation of goatpox along with questionaires.

    RESULTS: It was found that the susceptible age group were between 3 and 6 months old kids while higher infection rate occurred in those under the free-range rearing system. The clinical signs of pyrexia, anorexia, nasal discharge and lesions of pocks were not restricted to the skin but have extended into the lung and intestine. The pathogen had been confirmed in positive cases via PCR as goat pox with prevalence of 79.69%.

    CONCLUSIONS: The epidemiology of the current goat pox outbreak in North Vietnam denotes a significant prevalence which may affect the industry. This signals the importance of identifying the salient clinical signs and post mortem lesions of goat pox at the field level in order to achieve an effective control of the disease.

    Nasopharyngeal diphtheria is an acute infectious upper respiratory tract disease caused by toxigenic strains of Corynebacterium diphtheriae. We report a case of a young adult who presented to us with a short history of fever, sore throat, hoarseness of voice and neck swelling. He claimed to have received all his childhood vaccinations and had no known medical illnesses. During laryngoscopy, a white slough (or membrane) was seen at the base of his tongue. The epiglottis was also bulky and the arytenoids were swollen bilaterally. The membrane was sent to the microbiology laboratory for culture. A diagnosis of nasopharyngeal diphtheria was made clinically and the patient was treated with an antitoxin together with erythromycin, while awaiting the culture result. Nevertheless, the patient's condition deteriorated swiftly and although the laboratory eventually confirmed an infection by toxin-producing C. diphtheriae, the patient had already succumbed to the infection.

  14. Fulltext Knowledge, attitudes, and practices regarding Crimean-Congo hemorrhagic fever among general people: A cross-sectional study in Pakistan
    Jamil H, Din MFU, Tahir MJ, Saqlain M, Hassan Z, Khan MA, et al.
    PLoS Negl Trop Dis, 2022 Dec;16(12):e0010988.
    PMID: 36480553 DOI: 10.1371/journal.pntd.0010988
    BACKGROUND: Crimean-Congo hemorrhagic fever (CCHF) continues to pose a serious threat to the fragile healthcare system of Pakistan with a continuous increase of morbidity and mortality. The present study aimed to assess the knowledge, attitudes, and practices regarding CCHF among general people who resided in Pakistan.

    METHODS: An online cross-sectional survey design was applied, and a convenience sampling technique was used to recruit 1039 adult people from Pakistan. Data were collected from September 08 to October 12, 2021. The questionnaire consisted of a total of 32 questions in four parts assessing socio-demographics, as well as knowledge, attitudes, and practices regarding CCHF. All statistical analyses were performed using the Statistical Package for the Social Sciences (SPSS), and logistic regression analyses were performed to determine the factors associated with good knowledge, positive attitudes, and good practices.

    RESULTS: Alarmingly, 51.5% of participants heard about CCHF infection before administering the survey. Among these, 20.2%, 33.3%, and 48.2% of the study participants had demonstrated good knowledge, positive attitudes, and good practices, respectively. Binary logistic regression analysis revealed that education and income status had a significant impact on knowledge and attitudes (p<0.05). Similarly, the mean attitude scores differed significantly by age, education, and income status (p<0.05).

    CONCLUSIONS: The findings reflected inadequate levels of knowledge, attitudes, and practices regarding CCHF among general people in Pakistan which may regard as lower than expected. As CCHF is a highly contagious disease, it's urgent to initiate a comprehensive approach to handle the situation before it spreads further in Pakistan.

  15. Fulltext Circulation of West Nile virus in mosquitoes approximate to the migratory bird stopover in West Coast Malaysia
    Natasha JA, Yasmin AR, Sharma RSK, Nur-Fazila SH, Nur-Mahiza MI, Arshad SS, et al.
    PLoS Negl Trop Dis, 2023 Apr;17(4):e0011255.
    PMID: 37023172 DOI: 10.1371/journal.pntd.0011255
    Being a tropical country with a conducive environment for mosquitoes, mosquito-borne illnesses such as dengue, chikungunya, lymphatic filariasis, malaria, and Japanese encephalitis are prevalent in Malaysia. Recent studies reported asymptomatic infection of West Nile virus (WNV) in animals and humans, but none of the studies included mosquitoes, except for one report made half a century ago. Considering the scarcity of information, our study sampled mosquitoes near migratory bird stopover wetland areas of West Coast Malaysia located in the Kuala Gula Bird Sanctuary and Kapar Energy Venture, during the southward migration period in October 2017 and September 2018. Our previous publication reported that migratory birds were positive for WNV antibody and RNA. Using a nested RT-PCR analysis, WNV RNA was detected in 35 (12.8%) out of 285 mosquito pools consisting of 2,635 mosquitoes, most of which were Culex spp. (species). Sanger sequencing and phylogenetic analysis revealed that the sequences grouped within lineage 2 and shared 90.12%-97.01% similarity with sequences found locally as well as those from Africa, Germany, Romania, Italy, and Israel. Evidence of WNV in the mosquitoes substantiates the need for continued surveillance of WNV in Malaysia.

    PMID: 36898955 DOI: 10.1016/j.rvsc.2023.02.010
    African swine fever (ASF) is one of the highly contagious diseases of pigs that affect both domestic and wild pigs. The primary purpose of this research was to evaluate the online social attention on the ASF research to inform the research scientists and key stakeholders in the field by reporting the concise information of the most influential articles, social engagement, and impacts of the research. This study employed the altmetrics tool to evaluate the research papers. Bibliographic data of 100 articles were collected from Scopus; altmetric data was collected from the Altmetric.com database and analyzed using SPSS and Tableau. The articles were mainly mentioned on Twitter, followed by News Outlets and significant readers on Mendeley. Pearson correlation coefficients revealed a weak and insignificant correlation between Scopus Citation and Altmetric Attention Score (AAS). Mendeley Readership and Scopus Citation were moderately correlated. However, there was a significant positive correlation between the AAS and Mendeley readership. Using altmetric tools, the paper is the first research to shed light on the characteristics of ASF on social media.

    Clinical characteristics are essential for the correct diagnosis of diseases. The current review aimed to summarize the global clinical characteristics of the COVID-19 patients systematically and identify their diagnostic challenges to help the medical practitioners properly diagnose and for better management of COVID-19 patients. We conducted a systematic search in PubMed, Web of Science, Scopus, Science Direct, and Google Scholar databases for original articles containing clinical information of COVID-19 published up to 7th May 2020. Two researchers independently searched the databases to extract eligible articles. A total of 34 studies from 8 different countries with 10889 case-patients were included for clinical characteristics. The most common clinical symptoms were cough 59.6, fever 46.9, fatigue 27.8, and dyspnea 20.23%. The prominent laboratory findings were lymphocytopenia 55.9, elevated levels of CRP 61.9, aspartate aminotransferase 53.3, LDH 40.8, ESR 72.99, serum ferritin 63, IL-6 52, and prothrombin time 35.47%, and decreased levels of platelets 17.26, eosinophils 59.0, hemoglobin 29, and albumin 38.4%. CT scan of the chest showed an abnormality in 93.50% cases with bilateral lungs 71.1%, ground-glass opacity 48%, lesion in lungs 78.3%, and enlargement of lymph node 50.7%. Common comorbidities were hypertension, diabetes, obesity, and cardiovascular diseases. The estimated median incubation period was 5.36 days, and the overall case fatality rate was 16.9% (Global case fatality outside China was 22.24%: USA 21.24%, Italy 25.61%, and others 0%; whereas the case fatality inside the Hubei Province of China was found to be 11.71%). Global features on the clinical characteristics of COVID-19 obtained from laboratory tests and CT scan results will provide useful information to the physicians to diagnose the disease and for better management of the patients as well as to address the diagnostic challenges to control the infection.

    BMJ Case Rep, 2024 Apr 08;17(4).
    PMID: 38589245 DOI: 10.1136/bcr-2024-259938
    Listeriosis is a rare foodborne infection caused by Listeria monocytogenes It has been reported to be commonly found among the obstetric population, immunocompromised group and elderly, presumably due to the lower immunity status in these populations. Presentation in pregnancy is usually non-specific like fever, diarrhoea, respiratory tract symptoms and preterm rupture of membrane. These make the diagnosis challenging and may delay the correct management. We present a case of a female in her early 40s, gravida 4 para 0+3 at 27 weeks who presented with fever. She later developed preterm rupture of membrane 24 hours after admission. The leaking of liquor later changed from clear to meconium stained raising the suspicion of listeria chorioamnionitis, necessitating an emergency preterm delivery via caesarean section. The newborn acquired listeria infection and required ventilation support. He subsequently was discharged from neonatal unit after nearly 3 months of life.

  20. Fulltext The deadly ebola threat in the midst of an overwhelming dengue epidemic
    Besari AM, Md Noor SS, Lee YY
    Malays J Med Sci, 2014 Nov-Dec;21(6):9-13.
    PMID: 25897277 MyJurnal
    The recent death tolls and morbidities associated with two deadly viral haemorrhagic fevers (VHFs), i.e., Ebola and dengue, are simply shocking. By the end of August 2014, 65 672 people were afflicted with dengue fever (DF) in Malaysia, with 9505 from Kelantan, and there were 128 reported deaths. More astounding are the death tolls associated with Ebola: 3091 deaths from 6574 reported cases so far. It is not difficult to imagine the potential disaster if Ebola spreads beyond Africa. VHFs are characterised by an acute onset of fever, vascular disruption and a rapid progression to shock and death. The revised World Health Organization (WHO) 2012 classification (dengue with and without warning signs and severe dengue) is more clinically relevant and allows more streamlined admission. With good administrative support and public health and governmental efforts, the dengue epidemic in Malaysia is now more contained. However, there should be no laxity with the imminent lethal Ebola threat. Human-to-human transmission is an important mechanism for the spread of Ebola, and this calls for strict precautions regarding contact with any suspected cases. In contrast, the control and elimination of dengue would require successful control of the vectors and their breeding sites.
