    OBJECTIVE: Language and symbolic play require the same underlying symbolic ability and develop parallel to one another. The aim of this study was to determine the association between symbolic play and vocabulary in typically developing children and children with Down syndrome in Malaysia.

    METHODS: Twenty-five typically developing children and 25 children with Down syndrome aged between 12 and 36 months were involved in this study. They were recruited from an early intervention center and various kindergartens from the West Coast of Peninsular Malaysia. Their play skills were assessed using the Symbolic Play Test Second Edition, and information about their vocabulary was obtained through the MacArthur Bates Communicative Development Inventories that was filled out by their parents.

    RESULTS: There was a significant difference in the vocabulary and symbolic play scores of children with Down syndrome compared with typically developing children. There was also a positive correlation between symbolic play scores and receptive and expressive vocabulary scores for both groups of children.

    CONCLUSION: When providing intervention, speech-language pathologists need to promote the development of symbolic play in addition to language, given the association between the two. They should also look into introducing an augmentative and alternative communication system to the children who demonstrate age-appropriate symbolic play skills but have trouble with symbolic language production.

    Introduction: Pre-operative identification of patients with inadequate hamstring graft for anterior cruciate ligament reconstruction is still a subject of interest. The purpose of this study is to correlate dimension of a harvested dimensions graft with patient physical anthropometric variables.

    Materials and methods: This cohort study included 280 patients (male = 226, female = 54) scheduled for primary anterior cruciate ligament (ACL) reconstruction. Interrelationships between quadruple semitendinosus (ST) graft and anthropometric parameters (age, sex, height, weight, and BMI) were assessed using Pearson Correlation test and regression analysis. Difference among gender was analysed using Mann Whitney and t test. The observed graft diameter was also compared with the literature using Bland - Altman plot.

    Results: Mean age of cohort was 29 years (range, 17-50 years), mean height was 1.69m (range, 1.6-1.9m), mean weight was 75 kg (range, 50-116kg) and mean BMI was 26kg/m2 (range 16.65-40.40kg/m2). Mean quadruple length of harvested ST graft was 7cm (7.1±0.6 cm, range, 5.6-8.8cm) and mean diameter was 8mm (8.2±0.8mm, range, 6.5-10mm). Only height and weight were significantly correlated with graft length and diameter in both sex (p value <0.05). Female, compared to male, had significantly smaller (p<0.0001) and thinner graft (p<0.0001). There was a strong agreement between the literature and our observed graft diameter, but with an overestimated graft diameter in 18.5% of the cases.

    Conclusion: Among anthropometric parameter, only height and weight had moderate positive correlation with graft diameter. Males had longer and wider ST graft in contrast to age-matched female group.

    Purpose: To evaluate the efficacy of topical ketorolac tromethamine 0.5% given pre-emptively a day before, for alleviating pain in patients undergoing panretinal photocoagulation (PRP) treatment. Methods: A controlled single-blinded study was conducted on 33 patients with diabetic retinopathy (DR; severe nonproliferative DR, proliferative DR, or advanced diabetic eye disease) who required PRP treatment in both eyes simultaneously. Each eye of the patients was randomly assigned for ketorolac tromethamine 0.5% eyedrop or placebo. Both eyedrop bottles were randomly labeled. Eyedrops were self-administered by the patients, 4 times a day before the procedure (at 6 am, 12 noon, 6 pm, and 12 midnight) and every 15 min for 1 h (4 times) before the laser. Each patient was subjected to PRP using a Visulas 532s Zeiss device set to spot size 200 μm, time 0.10 s, and ∼600 burns in each eye. The pain score was evaluated immediately after treatment in each eye independently with Scott's visual analog scale (VAS) and the McGill Pain Questionnaire (MPQ). Results: VAS pain score in ketorolac-treated eyes (median 3.0, interquatile range [IQR] ±2.5) was lower than in placebo-treated eyes (median 5.0, IQR ±3.0). Total Pain Rate Index score from MPQ was lower in ketorolac-treated eyes (median 3.0, IQR ±3.0) than in placebo-treated eyes (median 3.0, IQR ±2.5). Both pain score differences are statistically significant with P ˂ 0.05. Conclusion: Topical ketorolac tromethamine 0.5% given pre-emptively a day before is effective in alleviating pain in patients undergoing PRP treatment.

    AIMS: The aim of this study was to assess subject wise and tooth wise distribution and prevalence of traumatic injuries to the anterior teeth of 2- to 6-year-old children.

    MATERIALS AND METHODS: A cross-sectional survey was performed. Primary maxillary and mandibular anterior teeth of 1,800 children aged between 2 years and 6 years, who attended 20 pre-schools in National Capital Region Delhi, India, were examined by a single examiner, and a questionnaire was filled in person by the parent/guardian. Andreasen's classification was used to classify the traumatic injuries. The Chi-square test was used to statistically analyze the variation in traumatic dental injuries (TDIs) with age and gender. Multiple logistic regression was used to determine the influence of independent variables on the occurrence of TDIs.

    RESULTS: The prevalence of TDIs was 17%. Significant and highly significant differences were found between boys and girls for cause and location of trauma (p < 0.05) and tooth type involved (p < 0.001) with boys being more prone to such injuries. The commonest cause of injury was due to falls and the location was playground. The teeth most commonly affected were the maxillary central incisors (36.9%) followed by maxillary lateral incisors (3.3%), and the least affected were the maxillary and mandibular canines (0.3%).

    CONCLUSION: The prevalence of traumatic injuries to the anterior teeth in 2- to 6-year-old children in National Capital Region of Delhi, India, was 17%. There is a need to run educational programs to increase parents' awareness of the risks of dental trauma and emphasize preventive measures.

    CLINICAL SIGNIFICANCE: Parents should be made aware of the widespread prevalence, risk factors, and consequences of trauma to primary dentition, so that they can seek appropriate care timely. The time elapsed between injury and dental care is of utmost importance.

    We suggest a method to improve quantum correlations in cavity magnomechanics, through the use of a coherent feedback loop and magnon squeezing. The entanglement of three bipartition subsystems: photon-phonon, photon-magnon, and phonon-magnon, is significantly improved by the coherent feedback-control method that has been proposed. In addition, we investigate Einstein-Podolsky-Rosen steering under thermal effects in each of the subsystems. We also evaluate the scheme's performance and sensitivity to magnon squeezing. Furthermore, we study the comparison between entanglement and Gaussian quantum discord in both steady and dynamical states.

    BACKGROUND: Viral hepatitis B and C (HBV, HCV) and non-alcoholic fatty liver disease (NAFLD) are the commonest etiologies of liver-related deaths in Malaysia. Herein, this study aims to explore and understand the knowledge and attitudes of the public toward liver-related health and diseases in Malaysia.

    METHODS: A cross-sectional, self-reported, web-based questionnaire was conducted among 500 adults between February and March 2020. Questionnaire items pertained to the knowledge and attitudes toward liver-related health and diseases.

    RESULTS: Half of the respondents were aged ≥35 years and 52.0% were males. Gaps in knowledge included the lack of awareness of different types of hepatitis, including the potential transmission risks and complications of HBV and HCV. About half acknowledged liver fibrosis and cirrhosis as key determinants of liver-related disease progression. A higher proportion rightly recognized the diagnostic test for HCV (40.8%) than HBV (30.0%) despite more being aware of HBV than HCV. Less than one-third were aware of the risk factors, screening tests, and complications of NAFLD. Despite the majority (92.8%) agreeing that regular screening was important for liver health, only 67.0% attended recent health screening and one-fifth were unlikely to seek medical consultation upon exposure to viral hepatitis risk factors. Reasons for this low urgency included the perception of being healthy, cost-related concerns, and societal discrimination.

    CONCLUSION: Robust education efforts are needed to raise awareness and empower the community with knowledge of liver-related diseases, particularly viral hepatitis and NAFLD in Malaysia.

    Tea is produced from the Camellia sinensis plant and can generally be divided into categories based on how they are processed. In general, green tea that is unfermented C. sinensis has been considered superior to black tea in health benefits. It contains a unique set of catechins that possess biological activity as antioxidant, anti-inflammatory and antiproliferative, which is potentially significant to the prevention and treatment of various forms of diseases. Oral cavity oxidative stress and inflammation, consequent cigarettes due to nicotine and acrolein, may be reduced in the presence of green tea polyphenols. In addition, green tea polyphenols can close down halitosis through modification of odorant sulfur components. Usually, green tea defends healthy cells from malignant transformation and locally has the ability to induce apoptosis in oral cancer cells. In unison, there is an increasing implication in the health benefits of green tea in the field of oral health. This review will cover recent findings on the therapeutic properties and anticancer health benefits of green tea.

    Persistent neutrophilic meningitis is an atypical form of chronic meningitis defined as clinical meningitis with a cerebrospinal fluid (CSF) analysis suggestive of neutrophilic pleocytosis that persists for more than one week despite giving empirical antimicrobial therapy. The predominant presentation of tubercular meningitis is with CSF lymphocytic pleocytosis and even if early phase of the disease presents with neutrophilic pleocytosis, no persistence is usually observed for more than one week. We hereby report the case of an immunocompetent man aged 25 years with tubercular meningitis manifesting as persistent neutrophilic meningitis which is very rare as an entity in tubercular meningitis (TBM). Patient was started on anti-tubercular therapy based on the granulomas in magnetic resonance imaging (MRI) of the brain after which there was a reduction in total cell count in CSF but persisting neutrophilic predominance. Patient improved clinically and was given a full course of anti-tubercular treatment (ATT) thereafter.

    Toxoplasma gondii is a public health risk in developing countries, especially those located in the tropics. Widespread infection may inflict a substantial burden on state resources, as patients can develop severe neurological defects and ocular diseases that result in lifelong loss of economic independence. We tested sera for IgG antibody from 493 eye patients in Malaysia. Overall age-adjusted seroprevalence was estimated to be 25% (95% CI: [21%, 29%]). We found approximately equal age-adjusted seroprevalence in Chinese (31%; 95% CI: [25%, 38%]) and Malays (29%; 95% CI: [21%, 36%]), followed by Indians (19%; 95% CI: [13%, 25%]). A logistic regression of the odds for T. gondii seroprevalence against age, gender, ethnicity and the occurrence of six types of ocular diseases showed that only age and ethnicity were significant predictors. The odds for T. gondii seroprevalence were 2.7 (95% CI for OR: [1.9, 4.0]) times higher for a patient twice as old as the other, with ethnicity held constant. In Malays, we estimated the odds for T. gondii seroprevalence to be 2.9 (95% CI for OR: [1.8, 4.5]) times higher compared to non-Malays, with age held constant. Previous studies of T. gondii seroprevalence in Malaysia did not explicitly adjust for age, rendering comparisons difficult. Our study highlights the need to adopt a more rigorous epidemiological approach in monitoring T. gondii seroprevalence in Malaysia.

    Choanal stenosis has recently been recognized as a late complication of radiation therapy for nasopharyngeal carcinoma. The management of velopharyngeal stenosis is challenging with high risk of restenosis. We report a case of velopharyngeal stenosis post-radiotherapy and illustrated the use of mitomycin-C to prevent restenosis. Mitomycin-C application has being shown useful adjunct to surgical technique in managing nasopharyngeal stenosis for surgeons.

    PURPOSE: Children with speech and language delay/disorder (SLD) in the developing language stage (DLS) are one of the largest populations served by speech-language pathologists (SLPs) working in paediatric settings. The aim of this study was to investigate the practise patterns adopted by Malaysian SLPs when managing these children.

    METHOD: A web-based questionnaire was developed to obtain information about SLPs' practises during assessment, planning and treatment.

    RESULT: A total of 53 SLPs completed the questionnaire. When assessing the children, participants either always or usually involved parents, suggesting that they understood the importance of family involvement in services provided. When planning goals, the SLPs relied mostly on their clinical experience and less on research evidence. Participants reported that, most often, they employed a one-to-one approach when providing treatment. There was, however, great variation in the frequency of treatment provided, reflecting the different workplaces of participants.

    CONCLUSION: Generally, findings from this study indicated that some practises employed by Malaysian SLPs when managing children with SLD in the DLS are on par with the best practise guidelines, but there is still room for improvement in certain areas such as team collaboration and evidence-based practise. Clinical and research implications are discussed.

    The Helicobacter pylori infection rate was determined in 124 consecutive patients with duodenal ulcers (DU), gastric ulcers (GU), duodenal erosions or gastric erosions diagnosed by endoscopy at a single institution in north-eastern peninsular Malaysia in 1996-97. Biopsies of the gastric antrum and body were subjected to the urease test, Gram staining of impression smears, culture and histopathological examination. Serology was undertaken on all patients using a locally validated commercial kit. Infection was defined as a positive result in at least one test. The infection rates were 20% (10/50), 21.2% (7/33), 16.7% (1/6) and 17.1% (6/35) in DU, GU, duodenal erosion and gastric erosion patients, respectively. The infection rate among Malays [7.0%, (6/86)] was lower than in non-Malays [47.4% (18/38)] (P < 0.001). There was a higher infection rate among males, who constituted 62.1% (77/124) of the sample. Seventy-eight patients (62.9%) were receiving non-steroidal anti-inflammatory drugs (NSAIDs) and 33 patients (26.6%) were neither receiving NSAIDs nor were infected with H. pylori. The H. pylori infection rate among peptic ulcer patients in this predominantly Malay rural population appears to be the lowest reported in the world thus far. Empirical H. pylori eradication therapy in peptic ulcer patients is clearly not indicated in this community. The possible reasons for the low prevalence of H. pylori infection are discussed.

    Schizophrenics (n = 250) and normal controls (n = 90) were studied to investigate and compare their dermatoglyphic patterns. Their fingerprint patterns were studied. The frequency of arches in the patient and control groups was similar. The frequency of loops in the control group was higher than in the patient group, and the trend was consistent in all the digits. The whorls in the patient group showed an increase over the control group in all the digits, although this finding was not statistically significant.

    ETHNOPHARMACOLOGICAL RELEVANCE: Traditional plant-derived medicines have enabled the mankind in curing the wide spectrum of diseases throughout the ages. Andrographis paniculata (Burm.f.) Nees, is one of the traditional plant used as a folk medicine for the management of inflammation, arthritis, viral-bacterial infections and other ailments in India, China, Malaysia and other South-East Asian countries. Its major bioactive compound; andrographolide, a diterpenoid, also exerts cytoprotective properties and is reported to be effective in neuroprotection, hepatoprotection, etc. AIM: The study is aimed to explore the role of andrographolide in treatment of complete freund's adjuvant (CFA) induced arthritis.

    MATERIALS AND METHODS: The influx of immune cells, release of pro-inflammatory cytokines and subsequent accumulation of synovial fluid (swelling) and pain manifest into the disease. The present study used CFA induced Balb/c mice model and treated them intraperitoneally with andrographolide and dexamethasone (used as a positive control) on alternate days for six days. After 6 days, blood and peritoneal macrophages were collected to evaluate the expression of various arthritic markers and paw edema was measured on all days.

    RESULTS: The in vitro and ex vivo experiments showed that andrographolide treated animal group had reduced paw edema, cell cytotoxicity and nitric oxide production than dexamethasone treated animal group. Further, the study revealed the mechanistic role of andrographolide in treatment of arthritis by suppressing battery of molecules like COX-2, NF-κB, p-p38, CD40, TNF-α, IL-1β and IL-6 involved in arthritis.

    CONCLUSION: The study showed the potent anti-arthritic effects of andrographolide and warrants further investigations on andrographolide for the development of safe and effective anti-arthritic drug.

    Aim and objective: The aim of this study was to evaluate and compare the antifungal efficacy of MTA Fillapex, Metapex, zinc oxide eugenol cement, Endomethasone, and Endoflas against Candida albicans.

    Materials and methods: Root canal exudates of 30 patients were tested against MTA Fillapex (Angelus), Metapex (BioMed), zinc oxide eugenol (Deepak Enterprise), Endomethasone (Septodont), Endoflas FS (Sanlor Laboratories), MTA (Angelus) (positive control), and glycerine (negative control). Children with failed endodontic cases were included in the study. Tube dilution and agar diffusion methods were used to check the antifungal efficacy of the root canal sealers. In tube dilution method, 24-well culture plates containing freshly mixed material along with Candida albicans were used. Wells containing MTA (Angelus) along with Sabouraud dextrose agar and Candida albicans served as positive control while glycerine along with Sabouraud dextrose agar and Candida albicans served as negative control. All plates were incubated at 37°C for 24 hours. Growth of the fungi was monitored after 24 hours by the presence of the turbidity. The samples were recultured to test the experimental material using agar well diffusion method, and the Petri plates were incubated for 24 hours and 72 hours. Zone of inhibition was measured after respective time period. Paired t test was used for the data analysis.

    Results: It was seen in tube dilution method Endomethasone showed least turbidity while maximum was shown by Metapex; similar results were seen in case of agar well diffusion method in which largest zone of inhibition was shown by Endomethasone while smallest was by Metapex.

    Conclusion: It was concluded that Endomethasone showed maximum efficacy against Candida albicans as compared to Metapex.

    Background and Aims: Host immune response is altered by a series of physiologic and pathologic factors like age, gender, inflammation, surgery, medication etc., The present study was conducted to evaluate differences in salivary IgA (S-IgA) levels among pedodontic subjects undergoing active orthodontic treatment with fixed and removable appliance. The levels of S- IgA were determined before 3 months and 6 months post active orthodontic treatment.

    Methods: A total of 40 healthy pedodontic subjects (aged 8-15 years) were recruited in the present study. They were equally divided into Group A (fixed orthodontic group) and Group B (removable orthodontic group) with 20 subjects each. 1.5 mL of saliva per subject was obtained before 3 and 6 months after treatment. Enzyme Linked Immunosorbent Assay (ELISA) technique was used for measurement of Salivary IgA levels.

    Results: Group A and B both showed significant rise in S-IgA levels 3 months and 6 months post active orthodontic treatment. Mean value of S-IgA 3 months post treatment in the saliva of children in group B and group A were (144.27 ± 5.32) and (164.0 ± 3.23) μg/ml respectively. While mean value of S-IgA after 6 months of treatment in group B and group A were (149.8 ± 6.02) and (166.4 ± 3.65) μg/ml respectively.

    Conclusion: Salivary Immunoglobulin A level values were significantly higher statistically in both group A and group B post active orthodontic treatment than before. The results however, showed that Group A (fixed orthodontic group) showed statistically significant higher levels of S-IgA than Group B (removable orthodontic group). Active orthodontic treatment triggered a stronger stimulus for oral secretory immunity, hence the increase in levels were detected. There is a significant positive correlation between S-IgA and active fixed as well as removable orthodontic treatment. Orthodontic treatment is hence a local immunogenic factor.
