    OBJECTIVES:
    The aims of this study are to determine the prevalence, attitudes and behaviours of medication storage and self-medication amongst female students at Universiti Sains Malaysia (USM).

    METHODS:
    A cross-sectional survey was conducted and cluster random sampling technique was used for respondent selection. A pre-piloted questionnaire was administered to female respondents so as to collect the data. Data was analyzed using SPSS version 12 and analysis was conducted using descriptive analysis procedures.

    RESULTS:
    Of the 481 participants (mean age; SD was 22.1; 3.3), 93.1% (n=448) students stated that they stored medicine in their rooms, while 70.7% (n=340) stated that they stopped taking a prescribed medicine without consulting a doctor. The prevalence of self-medication was 80.9% (n=389). The most common reasons for self-medication were related to their knowledge of their ailment and its treatment (58.0%), 14.4% thought it saved time and 8.5% mentioned that medication given by provider was not effective. The most common symptoms were otorhinolaryngology problems (22.5%), followed by respiratory disease (19.6%), Gastro Intestinal Tract (GIT) disease (18.1%) and headache/fever (16.8%). Commonly used medicines were analgesics & antipyretics (30.2%), ear, nose & throat drugs (10.8%), vitamins & minerals (10.8%), GIT drugs (8.5%), anti-infections (7.3%) and herbal medicines (3.5%). Prevalence of medicine storage and self-medication practice is high among educated female students in USM.

    CONCLUSIONS:
    There is a need to educate the students to ensure safe practice by increasing their awareness. Strict policies need to be implemented on the unrestricted availability of medicines so as to prevent the wastage of medicines.

    Objective: To review the clinical characteristic of vertigo in children.
    Method: A retrospective observational study was done on children who presented to a specialised vertigo clinic over period of six years. The patients’ case notes were retrieved from the medical record unit and reviewed. All patients were seen by an otologist who thoroughly took down history, completed ear, nose, throat and neurological examination.
    Result: Seven different causes were identified in 21 patients (86%) while no diagnosis was reached in three patients (12.5%). The most common cause of giddiness was childhood paroxysmal vertigo (33%) followed by benign paroxysmal positional vertigo (16.6%) and sensorineural hearing loss (12.5%). Other causes include chronic suppurative otitis media and anxiety disorder each accounting for 8.3%, one case of cholesteatoma and another case of ear wax each accounting for 4.1%.
    Conclusion: It is not uncommon for the children to be affected by vertigo. Management of vertigo in children should include a detailed history, clinical examination, audiological and neurological evaluation. Imaging should be performed in selected patients. The main cause of vertigo in our series is CPV. The outcome of most of the patients is good.

    This paper studied associations between ocular symptoms, rhinitis, throat and dermal symptoms, headache and fatigue in students by ethnicity and in relation to exposure to chemical microbial markers and fungal DNA in vacuumed dust in schools in Malaysia. A total of 462 students from 8 randomly selected secondary schools in Johor Bahru, Malaysia, participated (96% response rate). Dust was vacuumed from 32 classrooms and analysed for levels of five types of endotoxin as 3-hydroxy fatty acids (C10, C12, C14, C16 and C18 3-OH), muramic acid, ergosterol and five sequences of fungal DNA. Multiple logistic regression was applied. Totally 11.9% reported weekly ocular symptoms, 18.8% rhinitis, 15.6% throat and 11.1% dermal symptoms, 20.6% headache and 22.1% tiredness. Totally 21.1% reported pollen or furry pet allergy (atopy) and 22.0% parental asthma or allergy. Chinese students had less headache than Malay and Indian had less rhinitis and less tiredness than Malay. Parental asthma/allergy was a risk factor for ocular (odds ratio=3.79) and rhinitis symptoms (OR=3.48). Atopy was a risk factor for throat symptoms (OR=2.66), headache (OR=2.13) and tiredness (OR=2.02). There were positive associations between amount of fine dust in the dust samples and ocular symptoms (p<0.001) and rhinitis (p=0.006). There were positive associations between C14 3-OH and rhinitis (p<0.001) and between C18 3-OH and dermal symptoms (p=0.007). There were negative (protective) associations between levels of total endotoxin (LPS) (p=0.004) and levels of ergosterol (p=0.03) and rhinitis and between C12 3-OH and throat symptoms (p=0.004). In conclusion, the amount of fine dust in the classroom was associated with rhinitis and other SBS symptoms and improved cleaning of the schools is important. Endotoxin in the school dust seems to be mainly protective for rhinitis and throat symptoms but different types of endotoxin could have different effects. The ethnic differences in symptoms among the students deserve further attention.

    Purpose: Care at ICUs is expensive and variable depending on the type of care that the patients received. Knowing the characteristics of the patient and his or her disease is always useful for improving health services and cost containment.

    Patients and methods: An observational study was conducted at four different intensive care units of an academic medical institution. Demographic characteristics, disease-management casemix information, cost and outcome of the high costing decile, and the rest of the cases were compared.

    Results: A total of 3,220 discharges were included in the study. The high-cost group contributed 35.4% of the ICU stays and 38.8% of the total ICU expenditure. Diseases of the central nervous system had higher odds to be in the top decile of costly patients whereas the cardiovascular system was more likely to be in the non-high cost category. The high-cost patients were more likely to have death as an outcome (19.2% vs 9.3%; p<0.001). The most common conditions that were in the high-cost groups were craniotomy, other ear, nose, mouth, and throat operations, simple respiratory system operations, complex intestinal operations, and septicemia. These five diagnostic groups made up 43% of the high-cost decile.

    Conclusion: High-cost patients utilized almost 40% of the ICU cost although they were only 10% of the ICU patients. The chances of admission to the ICU increased with older age and severity level of the disease. Central nervous system diseases were the major problem of patients aged 46-69 years old. In addition to cost reduction strategies at the treatment level, detailed analysis of these cases was needed to explore and identify pre-event stage prevention strategies.

    BACKGROUND: Treatment of Class III malocclusion is related to redirecting the growth of mandible, which may have an impact on the pharyngeal airway.

    OBJECTIVE: To evaluate and compare the treatment effect of Reverse Twin-Block (RTB) and Reverse Pull Face Mask (RPFM) on Pharyngeal Airway Space (PAS) in early and late mixed dentition Class III samples.

    METHODS: Ninety-five mixed dentition Malay children with Class III malocclusion were included in this study. Data consists of 190 pre- and post-treatment lateral cephalograms of early (8-9 years) and late (10-11 years) mixed dentition Class III samples. forty-nine samples were under RTB and forty-six samples were under RPFM. Treatment changes were evaluated by McNamara airway analysis and changes in tongue and hyoid bone position.

    RESULTS: Both upper and lower pharyngeal airway width were increased after treatment with RTB and RPFM ruling out the chance of airway constriction. There was also posterior positioning of the tongue and hyoid bone indicating mandibular retrusion. No significant treatment changes were found on the Pharyngeal Airway Space by the factor age, gender or type of appliance.

    CONCLUSIONS: Both RTB and RPFM increased the Pharyngeal Airway Space and produced similar treatment effect. As age does not affect the treatment outcome significantly, treatment can be delayed until late mixed dentition stage.

    Observations and modeling studies have shown that during CO2 injection into underground carbonate reservoirs, the dissolution of CO2 into formation water forms acidic brine, leading to fluid-rock interactions that can significantly impact the hydraulic properties of the host formation. However, the impacts of these interactions on the pore structure and macroscopic flow properties of host rock are poorly characterized both for the near-wellbore region and deeper into the reservoir. Little attention has been given to the influence of pressure drop from the near-wellbore region to reservoir body on disturbing the ionic equilibrium in the CO2-saturated brine and consequent mineral precipitation. In this paper, we present the results of a novel experimental procedure designed to address these issues in carbonate reservoirs. We injected CO2-saturated brine into a composite core made of two matching grainstone carbonate core plugs with a tight disk placed between them to create a pressure profile of around 250 psi resembling that prevailing in reservoirs during CO2 injection. We investigated the impacts of fluid-rock interactions at pore and continuum scale using medical X-ray CT, nuclear magnetic resonance, and scanning electron microscopy. We found that strong calcite dissolution occurs near to the injection point, which leads to an increase in primary intergranular porosity and permeability of the near injection region, and ultimately to wormhole  formation. The strong heterogeneous dissolution of calcite grains leads to the formation of intra-granular micro-pores. At later stages of the dissolution, the internal regions of ooids become accessible to the carbonated brine, leading to the formation of moldic porosity. At distances far from the injection point, we observed minimal or no change in pore structure, pore roughness, pore populations, and rock hydraulic properties. The pressure drop of 250 psi slightly disturbed the chemical equilibrium of the system, which led to minor precipitation of sub-micron sized calcite crystals but due to the large pore throats of the rock, these deposits had no measurable impact on rock permeability. The trial illustrates that the new procedure is valuable for investigating fluid-rock interactions by reproducing the geochemical consequences of relatively steep pore pressure gradients during CO2 injection.

    Hand, Foot and Mouth Disease (HFMD) is caused by multiple Enterovirus (EV) serotypes mainly coxsackievirus A6 (CV-A6), coxsackievirus A16 (CV-A16) and Enterovirus 71 (EV-A71). Recurrent HFMD infections are rarely reported. An unusual rise in HFMD cases was reported in Mumbai during May-June 2018. Stool and throat swab specimens were referred from seven children from two hospitals for laboratory diagnosis. The age group of cases ranged from 9 months to 5 years with median age 13 months. Out of seven cases, three were males and four females. One 13-month-old female case was reported twice within 21 days. Stool, throat swab specimens were tested by pan enterovirus RT-PCR and also by virus isolation using human rhabdomyosarcoma cell line for detection of Enteroviruses. Out of seven HFMD cases, CV-A6 and CV-A16 viruses were isolated from five and two cases respectively. The phylogenetic analysis of CV-A6 viruses showed their similarity with CV-A6 viruses from Finland and China, whereas the two CV-A16 isolates showed similarity with those from Japan, France, China, Sarawak and Thailand. For the recurrent HFMD case, CV-A6 and CV-A16 were isolated from the stool specimens collected during the first and second episodes, respectively. There are no reports of isolation and molecular characterization of CV-A6 and CV-A16 viruses from recurrent HFMD cases. The present study reports molecular characterization of two Enterovirus serotypes CV-A6 and CV-A16 from a recurrent HFMD case, highlighting need of virological and molecular surveillance of HFMD.

    Newer second generation supraglottic airway devices may perform differently in vivo due to material and design modifications. We compared performance characteristics of the Ambu® AuraGain™ and LMA Supreme™ Second Seal™ in 100 spontaneously breathing anaesthetised patients in this randomised controlled study. We studied oropharyngeal leak pressures (OLP) (primary outcome) and secondarily, ease of insertion, success rates, haemodynamic response, time to insertion, and complications of usage. We found no significant difference in OLP between the AuraGain versus the LMA Supreme, mean (standard deviation, SD) 24.1 (7.4) versus 23.6 (6.2) cmH2O, P=0.720. First-attempt placement rates of the AuraGain were comparable to the LMA Supreme, 43/50 (86%) versus 39/50 (78%), P=0.906, with an overall 98% insertion success rate for the AuraGain and 88% for the LMA Supreme after three attempts, P=0.112. However, the AuraGain was deemed subjectively harder to insert, with only 24/50 (48%) versus 37/50 (74%) of AuraGain insertions being scored 1 = easy (on a 5 point scale), P=0.013, and also took longer to insert, 33.4 (SD 10.9) versus 27.3 (SD 11.4) seconds, P=0.010. The AuraGain needed a smaller volume of air (16.4 [SD 6.8] versus 23.0 [SD 7.4] ml, P <0.001) to attain intracuff pressures of 60 cmH2O, facilitated more successful gastric tube insertion (100% versus 90.9%, P=0.046), and had significantly decreased sore throat incidence (10% versus 38%, P=0.020). One AuraGain and six LMA Supremes failed to be placed within the stipulated 120 seconds trial definition of 'success'; these patients had risk factors for failed supraglottic insertion. In conclusion, both devices had similar OLPs and performed satisfactorily. However, the AuraGain resulted in less postoperative sore throat despite being harder to and taking longer to, insert.

    Objective: To describe the complete nucleocapsid (N) gene region of Middle East respiratory syndrome coronavirus (MERS-CoV) from imported case in Malaysia and the relations with human- and camel-derived MERS-CoV.

    Methods: Combination of throat and nasal swab specimens was subjected to viral RNA extraction. For screening, the extracted RNA was subjected to real-time RT-PCR targeting upstream of E gene, open reading frame 1b and open reading frame 1a. For confirmation, the RNA was subjected to RT-PCR targeting partial part of the RNA-dependent RNA polymerase and nucleocapsid, followed by amplification of complete N gene region. Nucleotide sequencing of the first Malaysian case of MERS-CoV was performed following the confirmation with real-time RT-PCR detection.

    Results: Initial analysis of partial RNA-dependent RNA polymerase and N gene revealed that the nucleotides had high similarity to Jeddah_1_2013 strain. Analysis of complete N gene region (1 242 nucleotides) from the case showed high similarity and yet distinct to the nucleotide sequences of camel-derived MERS-CoV.

    Conclusions: From the finding, there are possibilities that the patient acquired the infection from zoonotic transmission from dromedary camels.

    Background: The COVID-19 pandemic has resulted in many changes in the delivery of health service which not only affect the public as well as healthcare workers, and also among medical and nursing students who are currently undergoing their training. This study aims to determine the commitment and willingness of medical and nursing students in Sarawak in treating patients with COVID-19 and its associated factors.

    Methods: It was a cross-sectional study using online questionnaire, carried out in a public university in Sarawak, Malaysia. All medical and nursing students were invited to participate in this study. Data was entered and analysed using IBM SPSS version 22.

    Result: A total of 304 respondents participated in the study, with 81.6% female and 69.4% medical students. Majority of the respondents were most willing to take a medical history, do a physical examination, throat swabbing, draw blood and perform IV drip insertion. There was a high commitment among respondents to treat COVID-19 patients regardless of personal risks. Majority of the respondents also agreed that medical staff who are involved in treating COVID-19 patients should be receiving a salary increase and compensation should be given to affected healthcare families, and all non-medical staff should be involved in treating COVID-19 patients. About 71% agreed about a law mandating medical staffs to treat patient.

    Conclusion: The willingness and commitment of medical and nursing students to treat COVID-19 patients was high, indicating their potential work force as healthcare providers.

    In recent years, there has been concern that non-smokers may also be at risk from secondhand smoke exposure, especially children. This study was done to determine the prevalence of secondhand smoke exposure at home and the association between secondhand smoke exposure and respiratory symptoms among primary schoolchildren in Kota Bharu, Kelantan. This was a comparative cross-sectional study involving children, aged 10·12 years. A structured questionnaire was used to obtain the information on sociodemographic, respiratory symptoms and smokers in the house. A random sample of 10 from 95 primary schools in Kota Bharu was included. Six classes were randomly selected from each school, two classes each from each school year of primary 4·6. A total of 795 children completed the questionnaire during September 2003 till March 2004. 386 of children (48.6%) were boys and 409 children (51.4%) were girls. Most of the children were Malay (99.9%). A total of 442 (55.6%) children lived with at least 1 smoker in the house mainly from the smoking fathers. Significantly increased odds ratios due to secondhand smoke exposure were observed for most of the respiratory symptoms. The odds ratios (95% confidence interval) were 1.67 (1.18, 2.39) for cough in the morning, 1.59 (1.10, 2.30) for cough at night, 1.76 (1.16, 2.65) for cough most days for the previous 3 months, 1.57 (1.14, 2.17) for phlegm in the morning, 1.49 (1.08, Z.07) for phlegm during daytime or at night, 1.38 (1.03, 1.86) for nose problems in the morning, 1.40 (1.03, 1.90) for nose problems at night and 1.78 (1.14, 2.78) for throat problems at night, 1.55 (1.06, 2.26) for ever wheeze or diagnosed asthma by doctor, 1.57 (1.05, 2.36) for throat problems in the morning and 1.81 (1.15, 2.85) for throat problems during daytime. The odds ratios increased with increasing number of smokers at home for cough in the morning, cough most days for the previous 3 months, phlegm in the morning, ever wheeze or diagnosed asthma by doctor, throat problems in the morning, throat problems during daytime and throat problems at night. In view of the significant health risks posed to children by secondhand smoke, public health policies are needed to protect this vulnerable population. The aim of such policies Ls to ensure the right of every child to grow up in an environment free of tobacco smoke.

    ETHNOPHARMACOLOGICAL RELEVANCE: Fritillaria cirrhosa D. Don bulbs contain alkaloids and are one of the most intensively exploited alpine Himalayan medicinal species. In terms of proprietary medicines, our study shows that 210 F. cirrhosa products are offered by 46 suppliers, most of which (44) are situated in China and two in Nepal. A widespread commercial use is as one of the main ingredients in cough syrups. A well known example is "Nin Jiom Pei Pa Koa Herbal Cough & Throat Syrup", which typically contains more F. cirrhosa than any other herbal ingredient in the formulation. The biggest market for F. cirrhosa bulbs is China, where demand exceeds supply of this wild harvested species for use in traditional Chinese medicine (TCM). Cross-border trade from Nepal to China occurs in significant quantities. Bhutan also imports F. cirrhosa bulbs from Nepal. In addition, F. cirrhosa is registered as an active ingredient in traditional herbal medicinal preparations in Australia, Canada, Hong Kong SAR, Malaysia, Republic of Korea, Singapore and Taiwan. There is also an export trade in F. cirrhosa to Europe. Assessing how much F. cirrhosa is traded is complex, however, due to a "look-alike" challenge, as nine Chinese Fritillaria species are traded in Europe (Fritillaria cirrhosa, F. delavayi, F. hupehensis, F. pallidiflora, F. przewalskii, F. thunbergii, F. unibracteata, F. ussuriensis and F. walujewii).

    AIMS OF THE STUDY: The aims of this review were to assess the scale of the global trade in F. cirrhosa, and to synthesise studies of the impacts of wild harvest on F. cirrhosa populations and on the extent of emerging cultivation initiatives as an alternative to wild harvest.

    METHODS: Firstly, we reviewed published information on studies on impacts of wild F. cirrhosa harvest from across the geographic range of this species. Secondly, global trade data for F. cirrhosa were analysed.

    RESULTS: The principal demand for F. cirrhosa bulbs is in China, where hundreds of different companies produce Fritillaria preparations. Trade data also show that in 2013, China exported over 44 tonnes of F. cirrhosa bulbs to Taiwan and 26.7 tonnes to the Republic of Korea. Extensive commercial use and limited wild stocks result in a high price (2000 - 3800 CNY per kg (around US$ 303 -560 per kg in 2017)) for F. cirrhosa bulbs. Prices of cultivated Fritillaria bulbs are much lower (600-680 CNY per kg in 2017) than wild harvested bulbs. But due to very specific growth requirements of F. cirrhosa, cultivation is not yet able to meet total demand. The consequence is continued exploitation of wild stocks. At the same time, however, an increasing proportion of the demand is met by cultivation of alternative Fritillaria species that are easier to grow than F. cirrhosa. The air-dry mass of F. cirrhosa bulbs varies between 0.0917 and 0.1116 g per bulb. This represents 8960 - 10,900 bulbs/kg or 8.9 - 10.9 million bulbs per tonne. Current demand therefore represents billions of bulbs per year.

    CONCLUSIONS: Demand for F. cirrhosa bulbs, particularly from China, makes this species one of the most intensively harvested alpine Himalayan medicinal bulbs. Although F. cirrhosa is listed as a Class III protected species in China, billions of these tiny, wild harvested bulbs are sold per year. Due to demand exceeding supply, the price of F. cirrhosa bulbs has increased dramatically. Between 2002 and 2017, for example, the price of wild harvested F. cirrhosa bulbs increased over nine-fold, from the equivalent of US$60 in 2002 to US$560 per kg in 2017. To date, cultivation has been unable to meet the entire market demand for F. cirrhosa bulbs, although other Fritillaria species are successfully cultivated on a larger scale.

    Human respiratory syncytial virus (RSV) is an important cause of acute respiratory tract infection in infants and young children. Phylogenetic analysis for RSV in Malaysia has not been reported before. We investigated the genetic features of RSV in respiratory specimens from March to August 2011 with molecular methods. From a total of 130 throat swab and nasopharyngeal aspirate specimens, 54 (41.5%) were positive with RSV, identified by in-house real-time reverse transcriptase polymerase chain reaction (rRT-PCR) assay. Thirty-four out of 54 (63.0%) RSV positive patients were children below two years old and two (1.4%) were adults. Phylogenetic analysis showed 39 isolates were genotype GA5, 13 genotypes GA2, one genotype GA1 and one genotype GA7. The findings indicated four genotypes of RSV circulating in the country and the predominant genotype is GA5.

    Introduction: Scientific literature suggests that human papillomavirus (HPV) infection may be associated with oral squamous cell carcinoma (OSCC). However, knowledge regarding HPV-OSCC link among oral health professionals (OHP) has been insufficient. So, the aim of this study was to assess the knowledge about HPV associated OSCC among OHP working in dental faculties in Malaysia.

    Methodology: Ethical committee of the University approved this study. A validated, pre-tested questionnaire was sent electronically to 224 OHP. Questionnaire collected information regarding demography, knowledge about HPV-OSCC link, HPV vaccine, and willingness to educate patients about HPV OSCC link among the participants of this cross-sectional study. Data collected was analysed using "Stata/IC-13" and was summarised using descriptive statistics like frequency, percentage, mean and standard deviation.

    Results: Out of 179 participants, around 39% of the participant's opined virus was not a causative factor for OSCC. Around, 44% replied posterior portion of the tongue/oro-pharynx was the commonest site for HPV related OSCC, whereas 29% replied that lateral border of the tongue was the common site for HPV related OSCC. Forty one percent educated patients regarding HPV infection being a causative factor for OSCC. HPV vaccine can prevent OSCC was stated by 70% OHP. Only 12% were aware of the availability of HPV vaccine in Malaysia. Majority (99%), agreed that there is a need to offer continuing education programmes to dentists highlighting advances and preventive strategies in the fight against OSCC.

    Conclusion: Substantial increase in awareness is required among OHP regarding HPV-OSCC link.

    Lignocaine spray for anaesthetising the nasal mucosa for fibreoptic bronchoscopy often causes discomfort to the patient. We compared two techniques of applying nasal topical anaesthesia using either lignocaine spray (group A: 25 patients) or gel (group B: 30 patients) to assess patients' tolerance to the procedure. Both groups received 100 mg of lignocaine in the nostril, 40-50 mg to oropharynx, 120 mg to vocal cords and 40-100 mg to trachea and bronchi. Throat anaesthesia was the most common unpleasant part experienced by both groups of patients (34.5%), followed by examination of bronchi (30.6%) and nasal anaesthesia (21.8%). Significantly more patients in group A experienced discomfort or pain during nasal anaesthesia as compared to group B (p < 0.001). Patients' tolerance to the bronchoscopy was similar in both groups and the examination was performed satisfactorily in all patients. Thus, lignocaine gel is a simple technique, effective and less irritating as compared to lignocaine spray for topical nasal anaesthesia.

    Mycoplasma pneumoniae, Legionella pneumophila and Chlamydia pneumoniae are the most common bacterial agents, which account for 15-40%, 2-15% and 5-10% of atypical community-acquired pneumonia (CAP) respectively. These agents are mostly associated with infection in the outpatient setting. The aim of this study was to evaluate the frequency of these pathogens among patients with CAP attending outpatient clinics in Tehran. A cross-sectional study was carried out of 150 patients attending to educational hospitals in Tehran with CAP. M. pneumoniae, L. pneumophila and Chlamydia spp. were detected by PCR assay, targeting the P1 adhesion gene, macrophage infectivity potentiator (mip) gene and 16S rRNA gene respectively from throat swabs obtained from each patient. A total of 86 (57.3%) of 150 patients were women; median age was 50 years (interquartile range, 35-65 years). M. pneumoniae, L. pneumophila and Chlamydia spp. were detected in 37 (24.7%), 25 (16.7%) and 11 (7.3%) patients respectively; of these, 66 patients (44%) were infected at least by one of these three pathogens. The frequency of L. pneumophila was significantly higher among patients over 60 years old (p 0.03). Coinfection was detected in seven patients (4.7%); six were infected by M. pneumoniae and L. pneumophila, and only one was infected by L. pneumophila and Chlamydia spp. M. pneumoniae was the most prevalent agent of atypical CAP, and L. pneumophila was more likely to infect elderly rather than younger people. Further studies on the prevalence of CAP and its aetiologic agents are needed to improve the diagnosis and treatment of CAP patients.

    This study aims to assess the association between microbial composition, biofilm formation and chronic otorhinolaryngologic disorders in Malaysia. A total of 45 patients with chronic rhinosinusitis, chronic tonsillitis and chronic suppurative otitis media and 15 asymptomatic control patients were studied. Swab samples were obtained from these subjects. Samples were studied by conventional microbiological culturing, PCR-based microbial detection and Confocal Laser Scanning Microscopy (CLSM). Haemophilus influenzae, Staphylococcus aureus, Streptococcus pneumoniae, coagulase-negative staphylococci (CoNS) and other Streptococcus species were detected in subjects of both patient and control groups. Biofilm was observed in approximately half of the smear prepared from swab samples obtained from subjects of the patient group. Most of these were polymicrobial biofilms. S. aureus biofilm was most prevalent among nasal samples while H. influenzae biofilm was more common among ear and throat samples. Results from this study supported the hypothesis that chronic otorhinolaryngologic diseases may be biofilm related. Due to the presence of unculturable bacteria in biofilms present in specimens from ear, nose and throat, the use of molecular methods in combination with conventional microbiological culturing has demonstrated an improvement in the detection of bacteria from such specimens in this study.

    Nasopharyngeal carcinoma, a malignancy associated closely with Epstein-Barr virus (EBV), is prevalent among Chinese of Southern China origin. Epidemiological studies indicate a high prevalence of EBV in Asia with viral isolates having typical characteristics of the putative viral oncogene, latent membrane protein 1 (LMP-1), such as the loss of the Xho1 restriction site in Exon 1 and the 30-bp deletion in Exon 3. The EBV LMP-1 gene from throat washings of 120 nasopharyngeal carcinoma patients and 14 healthy individuals were analyzed. Similar analyses were also carried out on 30 and 12 postnasal space biopsies from nasopharyngeal carcinoma patients and healthy individuals, respectively. The 30-bp deletion was detected in 20% of nasopharyngeal carcinoma throat washes and in 100% of nasopharyngeal carcinoma postnasal space biopsies. Interestingly, 16% of the nasopharyngeal carcinoma biopsies possessed both the deleted and the undeleted variants, suggestive of dual infections. The notion of dual infections in nasopharyngeal carcinoma was further supported by the coexistence of both "F" and "f" (BamH1F region) EBV variants in 11% of the nasopharyngeal carcinoma biopsies. All of the throat washes and biopsies from the healthy controls showed the undeleted variant. The loss of the Xho1 restriction site was found with higher frequency both in throat washes and biopsies from patients with nasopharyngeal carcinoma. The discrepancy in the frequency of the 30-bp deletion between throat washes (20%) and postnasal space biopsies (100%) was an indication that this deletion is specific for viral isolates from primary tumour sites.
