  1. Fulltext A global comparison of implementation and effectiveness of materiovigilance program: overview of regulations
    Joshi D, Sharma I, Gupta S, Singh TG, Dhiman S, Prashar A, et al.
    Environ Sci Pollut Res Int, 2021 Nov;28(42):59608-59629.

    Medical devices, being life-saving tools, are considered to be a boon for healthcare system. However, in addition to their therapeutic effects, there are several ill consequences that are caused by these devices. An effective cohort vigilant system was needed to manage such adverse effects. This had led to the introduction of materiovigilance. Materiovigilance is the study and follow-up of occurrences that arise as a result from the usage of the medical equipment. It not only manages adverse events (AE) but also creates harmonization among countries. Keeping these objectives in focus, the principles, perspectives, and practices with regard to materiovigilance that are followed in the USA, Europe, China, Japan, Australia, Canada, and India are being compared. Such a comparison is essential, which will help us to understand the gaps in the current regulatory systems in the above-mentioned countries and furthermore will provide a comprehensive picture to the regulatory authorities to amend any existing laws if required. These amendments may ensure optimal patient safety by providing them a benign experience from the use of medical devices.

  2. Fulltext A medication-estimated health status measure for predicting primary care visits: the Long-Term Therapeutic Groups Index
    Dhabali AA, Awang R
    Health Policy Plan, 2010 Mar;25(2):162-9.
    PMID: 19923207 DOI: 10.1093/heapol/czp051
    BACKGROUND: Managed care is one of the means advocated for health care reforms. The Malaysian government has proposed managed care for its citizens. In the Malaysian private health care sector, managed care is practised on a small scale with crude risk adjustment. The main determinant of an individual's health service utilization is their health status (HS). HS is used as a risk adjuster for capitation payment. Prescribed medications represent a useful source for HS estimation. We aimed to develop and validate a medication-based HS estimate and to incorporate it in the Andersen model of health service utilization. This is a preparatory step in studying the feasibility of developing a model for risk assessment in the Malaysian context.
    METHODS: Data were collected retrospectively from an academic year from computerized databases in University Sains Malaysia (USM) about users of USM primary care services. A user is a USM health scheme beneficiary who made at least one visit in the academic year to USM-assigned primary care providers. Socio-demographic variables, enrolment period, medications prescribed and number of visits were also collected. Chronic illness medications and some non-chronic illness medications were used to calculate the Long-Term Therapeutic Groups Index (LTTGI) which is an estimate of the HS of users. Using a random 50% of users, weighted least square methods were used to develop a model that predicts a user's number of visits. The other 50% were used for validation.
    RESULTS: Socio-demographic variables explained 15% of variability in number of primary care visits among users. Adding the LTTGI improved the explanatory power of the model to 36% (P < 0.001). A similar contribution of the LTTGI was noted in the validation.
    CONCLUSIONS: The Long-Term Therapeutic Groups Index was successfully developed. Variability in number of primary care visits can be predicted by LTTGI-based models.

  3. Fulltext A microbiological study of genital ulcers in Kuala Lumpur
    Zainah S, Cheong YM, Sinniah M, Gan AT, Akbal K
    Med J Malaysia, 1991 Sep;46(3):274-82.
    PMID: 1839925
    The microbial aetiology of genital ulcers was studied in 249 patients (241 men and 8 women) attending a Sexually Transmitted Disease Clinic in Kuala Lumpur, Malaysia. Herpes simplex virus type 2 was isolated in 48 (19.2%) patients, Haemophilus ducreyi from 22 (8.8%), Neisseria gonorrhoeae from seven (2.8%) and Chlamydia trachomatis from four (1.6%). Syphilis was diagnosed in 18 (7.2%) patients on the basis of dark field microscopy. Two (0.8%) patients were found to have both chancroid and syphilis and one (0.5%) had both gonorrhoea and syphilis. No organism was isolated in the remaining 151 (61.5%) patients. Overall, the accuracy of clinical diagnosis was 58% for single infection, 67% for herpes, 63% for syphilis, 47% for chancroid and 0% for lymphogranuloma venereum. Therefore, our study confirms the need for laboratory tests to diagnose accurately the aetiology of genital ulcer disease.

  4. A molecular epidemiologic study of thalassemia using newborns' cord blood in a multiracial Asian population in Singapore: results and recommendations for a population screening program
    Kham SK, Yin SK, Quah TC, Loong AM, Tan PL, Fraser A, et al.
    J Pediatr Hematol Oncol, 2004 Dec;26(12):817-9.
    PMID: 15591902
    DNA technology provides a new avenue to perform neonatal screening tests for single-gene diseases in populations of high frequency. Thalassemia is one of the high-frequency single-gene disorders affecting Singapore and many countries in the malaria belt. The authors explored the feasibility of using PCR-based diagnostic screening on 1,116 unselected sequential cord blood samples for neonatal screening. The cord blood samples were screened for the most common reported alpha- and beta-thalassemia mutations in each ethnic group (Chinese, Malays, and Indians) in a multiracial population. The carrier frequency for alpha-thalassemia mutations was about 6.4% in the Chinese (alpha deletions = 3.9%, alpha deletions = 2.5%), 4.8% in Malays, and 5.2% in Indians. Only alpha deletions were observed in the Chinese. The carrier frequency for beta-thalassemia mutations was 2.7% in the Chinese, 6.3% in Malays, and 0.7% in Indians. Extrapolating to the population distribution of Singapore, the authors found a higher overall expected carrier frequency for alpha- and beta-thalassemia mutations of 9% compared with a previous population study of 6% by phenotype. The highly accurate results make this molecular epidemiologic screening an ideal method to screen for and prevent severe thalassemia in high-risk populations.

  5. A national epidemiological survey of oral mucosal lesions in Malaysia
    Zain RB, Ikeda N, Razak IA, Axéll T, Majid ZA, Gupta PC, et al.
    Community Dent Oral Epidemiol, 1997 Oct;25(5):377-83.
    PMID: 9355776
    The prevalence of oral mucosal lesions in Malaysia was determined by examining a representative sample of 11,707 subjects aged 25 years and above throughout the 14 states over a period of 5 months during 1993/1994. A two-stage stratified random sampling was undertaken. A predetermined number of enumeration blocks, the smallest population unit in the census publication, was selected from each state. With the selected enumeration block, a systematic sample of living quarters was chosen with a random start. The survey instrument included a questionnaire on sociodemographic characteristics and a clinical examination. The clinical examination was carried out by 16 specially trained dental public health officers and the diagnosis calibrated with a final concordance rate of 92%. The age in the sample ranged from 25 to 115 years with a mean of 44.5+/-14.0. The sample comprised 40.2% males and 59.8% females; 55.8% were Malays, 29.4% Chinese, 10.0% Indians and 1.2% other ethnic groups. Oral mucosal lesions were detected in 1131 (9.7%) subjects, 5 (0.04%) had oral cancer, 165 (1.4%) had lesions or conditions that may be precancerous (leukoplakia, erythroplakia, submucous fibrosis and lichen planus) and 187 (1.6%) had betel chewer's mucosa. The prevalence of oral precancer was highest amongst Indians (4.0%) and other Bumiputras (the indigenous people of Sabah and Sarawak) (2.5%) while the lowest prevalence was amongst the Chinese (0.5%).

  6. Fulltext A new genus and species of arboreal toad with phytotelmonous larvae, from the Andaman Islands, India (Lissamphibia, Anura, Bufonidae)
    Chandramouli SR, Vasudevan K, Harikrishnan S, Dutta SK, Janani SJ, Sharma R, et al.
    Zookeys, 2016.
    PMID: 26877687 DOI: 10.3897/zookeys.555.6522
    A new bufonid amphibian, belonging to a new monotypic genus, is described from the Andaman Islands, in the Bay of Bengal, Republic of India, based on unique external morphological and skeletal characters which are compared with those of known Oriental and other relevant bufonid genera. Blythophryne gen. n. is distinguished from other bufonid genera by its small adult size (mean SVL 24.02 mm), the presence of six presacral vertebrae, an absence of coccygeal expansions, presence of an elongated pair of parotoid glands, expanded discs at digit tips and phytotelmonous tadpoles that lack oral denticles. The taxonomic and phylogenetic position of the new taxon (that we named as Blythophryne beryet gen. et sp. n.) was ascertained by comparing its 12S and 16S partial genes with those of Oriental and other relevant bufonid lineages. Resulting molecular phylogeny supports the erection of a novel monotypic genus for this lineage from the Andaman Islands of India.

  9. A new species of Clidicus with asymmetrical parameres (Coleoptera, Staphylinidae, Scydmaeninae)
    JaŁoszyŃski P
    Zootaxa, 2018 Mar 20;4399(1):141-145.
    PMID: 29690338 DOI: 10.11646/zootaxa.4399.1.12
    Clidicus Laporte, 1832 currently comprises 27 species distributed in India (Karnataka, Tamil Nadu), Sri Lanka, Indonesia (Java, Kalimantan, Sumatra), Malaysia (Sabah, Sarawak), Laos, Vietnam, the Philippines (Mindanao), China (Hainan) and Australia (Queensland). Some species have conspicuously large adults reaching 8.5 mm, and they represent the largest known Scydmaeninae. Species of Clidicus were relatively poorly known until recently, when Orousset (2014) revised a large portion of this genus and described several new species. Other major studies include Besuchet (1971), who described Sri Lankan species, Jałoszyński et al. (2003) who recorded four new species from Vietnam and Laos, Jałoszyński (2009) with the first description of a Philippine species, and Zhou Li (2015), who discovered the first species in China. Another new species, representing the second Clidicus occurring in the Philippines, is described below.

  10. A new species of genus Nishada Moore, 1878 (Lepidoptera, Erebidae, Arctiinae) from India
    Joshi R, Kirti JS, Singh N
    Zootaxa, 2016 Oct 28;4179(1):128-132.
    PMID: 27811698 DOI: 10.11646/zootaxa.4179.1.10
    Genus Nishada Moore (1878) was proposed as a monotypic genus, under subfamily Lithosiinae, family Lithosiidae (now Lithosiini), including only Nishada flabrifera Moore (1878) from Calcutta (now as Kolkata), India. The genus is distributed from China to India, Thailand, Malaysia and up to Australia. The Indian fauna of Nishada is reported from North-East Himalayas, West Bengal (Kolkata) and South India. Members of this genus are unmarked, yellow to brown with short and broad wings. Genus Nishada has been taxonomically dealt by many authors but awaits thorough revision.

    HISTORY: Hampson (1900) included a total of ten species: Nishada niveola Hampson, 1900, Nishada syntomioides (Walker, 1862), Nishada impervia (Walker, 1865), Nishada marginalis (Felder 1875), Nishada tula Swinhoe, 1900, Nishada nodicornis (Walker 1862), Nishada rotundipennis (Walker 1862), Nishada flabrifera Moore, 1878, Nishada sambara (Moore 1859) and Nishada xantholoma (Snellen 1879). Swinhoe (1902) and Hampson (1911) then described two new species, Nishada melanistis and Nishada brunneipennis, respectively, followed by Rothschild (1912, 1913) who described a further seven new species, Nishada brunnea, Nishada flavens, Nishada testacea, Nishada griseoflava, Nishada fuscofascia, Nishada louisiadensis and Nishada aurantiaca, bringing the total to 19 species. Strand (1922) catalogued only 13 of these species in Nishada, transferring N. brunnea and N. fuscofascia to genus Scoliacma Meyrick (1886); N. testacea, N.griseoflava and N. louisiadensis Rothschild to Eilema Hübner (1819) and synonymising N. flavens with N. sambara. Next, Matsumura (1927) described N. formosibia, followed by two more species, N. aureocincta Debauche, 1938 and N. benjaminea Roepke, 1946. Holloway (2001) synonymised N. nodicornis with N. rotundipennis and added the description of a new subspecies, Nishada chilomorpha adunca Holloway, 2001 from Borneo, indicating a distributional range as far as North East India. The nominotypical subspecies, N. c. chilomorpha was suggested to be restricted to its type locality of Java. Bucsek (2012) added Nishada cameronensis, Dubatolov & Bucsek (2013) described Nishada schintlmeisteri and Bucsek (2016) described Nishada temenggora. So, at present, Nishada comprises19 species, of which three are known from India (Singh et al. 2014). Herein, we describe one further species, Nishada pseudochilomorpha Joshi & Singh sp. nov., from Jatinga (Assam, India). In addition, new distributional records are reported for N. flabrifera.

    Virology, 2000 Nov 10;277(1):6-13.
    PMID: 11062030
    As a simian species, the langurs are not known to harbor simian retroviruses, except for one report on a simian Type D endogenous retrovirus from the spectacled langur (Trachypithecus obscurus) from Malaysia. The present report describes for the first time natural infection of the common Hanuman langur (Semnopithecus entellus) from India by a novel simian retrovirus (SRV). The new SRV is phylogenetically related to but distinct from the three molecularly characterized serotypes, SRV 1-3, of the five known serotypes of SRVs, based on sequence analyses from the 3'orf and env regions of the viral genome. The novel SRV isolated from the Indian Hanuman langur is provisionally named SRV-6.

    PMID: 3796347
    Selected students were subjected to a general health appraisal including vision and hearing tests by teachers, nurses and finally a medical officer. The findings of all three examiners were then compared taking the results of the medical officer as the indicator of accuracy. The findings of the survey indicated that the problems of school children were similar to those reported by other workers and by MCH Division of the Ministry of Health namely dental caries, head lice, malnutrition, skin infections and visual disability. Other problems like skeletal deformity and abnormalities of heart, lung, speech and behaviour were extremely uncommon and formed only 1.5% of the total. Teachers and nurses performed extremely well in relation to the doctor with 93% and 95.8% concurrence respectively in detecting these abnormalities. Teachers were also requested to give a feedback on their view of and role in the SHS as well as problems faced in following the school health card. The majority perceived the SHS as a joint effort between the Ministry of Health and Education and agreed that they had a role to play in the SHS. Many teachers also indicated a willingness to carry out the various tasks in the SHS. The main problem in filling the school health card seemed to be in getting relevant details from parents though over 50% of teachers complained that there were too many details to fill. The role of teachers in the SHS is discussed in the light of the findings of the study and recommendations are made.

    A cross sectional study to determine general health and body composition was conducted for comparison between rural samples (Teluk Intan, Perak) and urban samples (Klang Valley, Selangor). Systematic random sampling was used in Z health clinics in Klang Valky and 4 health clinics in Telult Intan, Perak The results showed that urban population was more heterogeneous (Malay 63.7%, Indian 19.8%, Chinese 14.9%) compared with the rural population (Malay 75%, Indian 22.1%, Chinese 2.9%). Mean age for urban population was 44 2 1.6 years and for rural was 50 i 14.4 years. There was significant difference in the BMI (p < 0.05) between urban and rural populations where more people in the urban areas had higher BMI. There was a significant difference in the waist hip ratio (p < 0.05) between urban and rural areas where more people in the urban areas had above normal waist hip ratio. There was no significant difference in chronic diseases suffered and family medical history of the rural and urban samples.

  18. A population-based survey of mental disorders in Singapore
    Chong SA, Abdin E, Vaingankar JA, Heng D, Sherbourne C, Yap M, et al.
    Ann Acad Med Singap, 2012 Feb;41(2):49-66.
    PMID: 22498852
    INTRODUCTION: Mental illnesses are not only a growing public health concern but also a major social and economic issue affecting individuals and families throughout the world. The prevalence of mental disorders, the extent of disability caused by these disorders, and services utilisation of these patients has been well studied in developed countries. The aim of this study was to establish the prevalence of select mental disorders and their associated sociodemographic correlates in the adult Singapore resident population.

    MATERIALS AND METHODS: This was a cross-sectional, populationbased, epidemiological study of adult Singapore residents aged 18 years and above. The subjects were randomly selected using a disproportionate stratified sampling method. The diagnoses of selected mental disorders including major depressive disorder (MDD), dysthymia, bipolar (bipolar I & II) disorders, generalised anxiety disorder (GAD), obsessive compulsive disorder (OCD), alcohol abuse and alcohol dependence were established using the Composite International Diagnostic Interview, which is a fully structured diagnostic instrument that assesses lifetime and 12-month prevalence of mental disorders.

    RESULTS: Among the 6616 respondents (response rate of 75.9%), 12.0% had at least one lifetime affective, anxiety, or alcohol use disorders. The lifetime prevalence of MDD was 5.8% and that of bipolar disorder was 1.2%. The combined lifetime prevalence of the 2 anxiety disorders, GAD and OCD was 3.6%, with the latter being more common than GAD (0.9% and 3.0% respectively). The lifetime prevalence of alcohol abuse and dependence were found to be 3.1% and 0.5% respectively. Age, gender, ethnicity, marital status and chronic physical illnesses were all significant correlates of mental disorders.

    CONCLUSION: The identified associated factors would help guide resource allocation, policy formulation and programme development in Singapore.
