  1. Fulltext Excision of tracheocutaneous fistula under local anaesthesia
    Irfan Mohamad, Yusri Musa, M.
    Archives of Orofacial Sciences, 2009;4(1):29-31.
    MyJurnal
    Tracheocutaneous fistula (TCF) is a known complication of tracheostomy. It can cause problems such as saliva leak, predispose to infection from external skin into respiratory tract and cosmetically not acceptable. Treatment of the underlying infection is paramount important. Persistence of tract after sufficient duration of observation period should be surgically treated. Cases reported in the literature are mainly regarding paediatric TCF and the procedures are usually done under general anesthesia. We describe a case of surgical treatment of an adult TCF which was done under local anaesthesia.

    Ng KF, Kee Tan K, Chok MC, Zamil Mohd Muzzamil N, Choo P, Paramasivam U, et al.
    J Trop Pediatr, 2017 Dec 01;63(6):447-453.
    PMID: 28334949 DOI: 10.1093/tropej/fmx011
    This prospective observational study aims to determine the incidence, predictors and clinical features of Mycoplasma hominis (MH), Ureaplasma urealyticum (UU) and Chlamydia trachomatis (CT) respiratory colonization in infants <37 weeks of gestation. A total of 200 preterm newborns admitted to a tertiary center in Malaysia between 2013 and 2015 for increased breathing effort had their respiratory secretions tested for these bacteria by polymerase chain reaction. Fifteen of the 200 (7.5%) infants were detected to have these organisms in their respiratory tracts. Preterm prelabor rupture of membrane was associated with positive detection (odds ratio: 3.7; 95% confidence interval: 1.2-11.3). Seventy-three of the 200 (36.5%) infants were given macrolide for presumed infection but only 4.1% (3 of 73) were positive for these organisms. The incidence of UU respiratory colonization among preterm infants in our center is lower than other published reports, while the frequency of MH and CT isolation is comparable with many studies. There should be judicious use of empirical antibiotics for presumed UU, MH and CT infection in preterm infants.

  4. Fulltext Influenza outbreaks during World Youth Day 2008 mass gathering
    Blyth CC, Foo H, van Hal SJ, Hurt AC, Barr IG, McPhie K, et al.
    Emerg Infect Dis, 2010 May;16(5):809-15.

    Influenza outbreaks during mass gatherings have been rarely described, and detailed virologic assessment is lacking. An influenza outbreak occurred during World Youth Day in Sydney, Australia, July 2008 (WYD2008). We assessed epidemiologic data and respiratory samples collected from attendees who sought treatment for influenza-like illness at emergency clinics in Sydney during this outbreak. Isolated influenza viruses were compared with seasonal influenza viruses from the 2008 influenza season. From 100 infected attendees, numerous strains were identified: oseltamivir-resistant influenza A (H1N1) viruses, oseltamivir-sensitive influenza A (H1N1) viruses, influenza A (H3N2) viruses, and strains from both influenza B lineages (B/Florida/4/2006-like and B/Malaysia/2506/2004-like). Novel viruses were introduced, and pre-WYD2008 seasonal viruses were amplified. Viruses isolated at mass gatherings can have substantial, complex, and unpredictable effects on community influenza activity. Greater flexibility by public health authorities and hospitals is required to appropriately manage and contain these outbreaks.

    Intense and prolonged exercise leads to immune suppression, causing upper respiratory tract infections (URTI). A proprietary standardized dietary supplement, IQP-AS-119 has been previously developed to aid immune responses under such conditions. The current randomized, double-blind, placebo-controlled pilot study aimed to investigate the effects of IQP-AS-119 on marathon runners. A total of 80 participants were randomized equally into groups receiving either placebo (P group) or IQP-AS-119 (V group) treatment, starting 3 weeks before and for 14 days after the marathon. Benefit assessment was performed using different questionnaires. Post-marathon, the V and P groups reported 1±2.38 and 2.11±3.25 days with upper respiratory tract symptoms (URTS), respectively (P=0.038). During the 14 days post-marathon, 20.0% of the participants in the V group compared with 44.4% in the P group reported URTS (P=0.042). The V group reported significantly milder URTS compared with the P group on Days 9, 12, 13 and 14 post-marathon (P<0.05). The total Perceived Stress Questionnaire-20 score on days 2-14 were significantly lower for the V group compared with the P group (P=0.035). In the Short Form 12 Health Survey, the V group exhibited significant improvement in mental composite score on days -5 to 14 compared with the P group (P=0.038). In the overall treatment effect assessment, there were no statistically significant differences between the groups. The IQP-AS-119 was rated 'very good' or 'good' by investigators and participants, respectively, for 71 and 65% of the participants. The tolerability of IQP-AS-119 was rated as 'very good' or 'good' by both investigators and 95% of participants. No clinically relevant differences were observed between groups regarding adverse events or other safety parameters. Therefore, IQP-AS-119 was demonstrated to reduce the incidence and severity of URTI in marathon runners. Given its good tolerability profile, IQP-AS-119 may be a good nutritional supplement for the reduction of URTS in susceptible individuals.

    In the recent years, an extensive number of scientific researches on occupational diseases have been done to
    identify occupations at high risk of inducing diseases. There are many categories of occupational diseases, and unitary
    of them are occupational respiratory diseases. This study was conducted in a tea factory located in Cameron Highlands,
    Malaysia, with an output of 600,000.00 kg per annum. Its objective was to evaluate respiratory diseases among the
    workers, conducted via questionnaires, interviews and lung functional tests. A total of 38 workers participated in this
    study, 19 in the exposed group and 19 in the control group. The most common chronic symptoms for the exposed
    group are wheezing, dyspnea (short of breath) and phlegm. The result shows that, among the tea processing workers,
    the exposed group suffer from respiratory diseases.

    Zulkifli I, Fauziah O, Omar AR, Shaipullizan S, Siti Selina AH
    Vet Res Commun, 1999 Mar;23(2):91-9.
    PMID: 10359153
    Two experiments were conducted to evaluate the effect of formaldehyde vaporization of a hatcher on the tracheal epithelium of chick embryos, and on the production performance and behaviour of commercial broiler chicks. In experiment 1, chick embryos were exposed to 23.5 ppm of formaldehyde vapour during the last 3 days of incubation. Tracheal samples were taken at 0, 6, 30 and 54 h after exposure to formaldehyde and examined by scanning electron microscopy for pathological changes. Observable lesions included excessive accumulation of mucus, matted cilia, loss of cilia and sloughing of the epithelium. The lesions were more severe in chicks exposed for 54 h as compared to those exposed for 6 or 30 h. In experiment 2, 60 chicks that had been exposed to formaldehyde vapour as above and 60 control chicks were used to investigate the effect of formaldehyde fumigation on production performance and behaviour. Formaldehyde vaporization resulted in higher weekly (days 0-6 and 21-27) and total (days 0-41) feed intake and poorer weekly (days 0-6, 7-13, 21-27 and 28-34) and overall (days 0-41) feed conversion ratios. Body weight, mortality and behaviour (eating, drinking, sitting and standing activities) were not affected by formaldehyde fumigation.

  9. Antimicrobial susceptibility pattern of clinical isolates of Pseudomonas aeruginosa in a tertiary care hospital
    Raja NS, Singh NN
    J Microbiol Immunol Infect, 2007 Feb;40(1):45-9.
    PMID: 17332906
    BACKGROUND AND PURPOSE: Pseudomonas aeruginosa is an important cause of morbidity and mortality in hospitalized, critically ill patients and patients with underlying medical conditions such as cystic fibrosis, neutropenia, and iatrogenic immunosuppression. The prevalence of multiresistant P. aeruginosa isolates has been increasing. The aim of this study was to determine the antimicrobial susceptibility patterns in P. aeruginosa strains isolated at a university teaching hospital in Kuala Lumpur, Malaysia.
    METHODS: The Laboratory Information System of the microbiology department was retrospectively reviewed to determine the susceptibility patterns of P. aeruginosa isolates to anti-pseudomonal antibiotics, from January to June 2005. Disk diffusion methods were employed and results were interpreted according to National Committee for Clinical Laboratory Standards guidelines.
    RESULTS: 505 clinical isolates of P. aeruginosa were tested. Major sources of these isolates included respiratory tract, wound, urine and blood. The rates of antimicrobial resistance of isolates were 6.73% to amikacin, 12.9% to gentamicin, 10.1% to netilmicin, 10.9% to ceftazidime, 11.3% to ciprofloxacin, 9.9% to imipenem, 10.8% to piperacillin, 9.4% to piperacillin-tazobactam and 0% to polymyxin B. Of the 505 isolates, 29 (5.74%) were found to be multidrug-resistant; these were most commonly isolated from respiratory tract specimens of patients in surgical units, followed by respiratory tract specimens in patients in medical units.
    CONCLUSIONS: The data in this study showed low rates of antibiotic resistance among P. aeruginosa isolates. Combinations of aminoglycosides plus beta-lactams or quinolones should be the appropriate choice for empirical therapy in P. aeruginosa infections. Active antibiotic susceptibility testing and surveillance should be continued in order to curtail the problem of antibiotic resistance.

  10. Fulltext Protective effects of Mucuna pruriens seed extract pretreatment against cardiovascular and respiratory depressant effects of Calloselasma rhodostoma (Malayan pit viper) venom in rats
    Fung SY, Tan NH, Sim SM
    Trop Biomed, 2010 Dec;27(3):366-72.
    PMID: 21399576 MyJurnal
    The protective effects of Mucuna pruriens seed extract (MPE) against the cardio-respiratory depressant and neuromuscular paralytic effects induced by injection of Calloselasma rhodostoma (Malayan pit viper) venom in anaesthetized rats were investigated. While MPE pretreatment did not reverse the inhibitory effect of the venom on the gastrocnemius muscle excitability, it significantly attenuated the venom-induced cardio-respiratory depressant effects (p < 0.05). The protection effects may have an immunological mechanism, as indicated by the presence of several proteins in the venom that are immunoreactive against anti-MPE. However, we cannot rule out the possibility that the pretreatment may exert a direct, non-immunological protective action against the venom.

  11. Ultrastructural pathology of the upper respiratory tract of rabbits experimentally infected with Pasteurella multocida A:3
    Al-Haddawi MH, Jasni S, Zamri-Saad M, Mutalib AR, Sheikh-Omar AR
    Res Vet Sci, 1999 Oct;67(2):163-70.
    PMID: 10502487
    Twenty-four 8 to 9 week-old Pasteurella multocida -free rabbits were divided into three equal groups, the first group was pretreated with hydrocortisone and inoculated intranasally with pasteurella multocida serotype A:3. The second group was inoculated intranasally with P. multocida without hydrocortisone treatment. The third group was inoculated with phosphate buffered saline only and used as a control group. Pasteurella multocida was isolated from the nasal cavity of all infected rabbits in group 1 and 2 and from the trachea of seven rabbits in group 1 and five rabbits in group 2. This study was conducted to observe the ultrastructural changes of the upper respiratory tract of hydrocortisone treated and non-treated rabbits infected with P. multocida serotype A:3. The ultrastructural changes detected in infected rabbits were ciliary destruction and deciliation of the ciliated epithelial cells, cellular swelling, goblet cell hyperplasia and endothelial cell damage. Pasteurella multocida was observed attached to the degenerated cilia, microvilli and mucus. Pasteurella multocida infection was associated with inflammatory responses, which may have caused tissue damage. It is possible that hydrocortisone modulates the severity of infection as an immune suppressor and an inhibitor of goblet cell secretion.

    Novel coronavirus disease, the latest world pandemic is one of the most contagious viral infections to date. There has been a lack of uniformity on recognizing this condition clinically because of poorly understood pathophysiology and clinical nature. Also due to ongoing clinical trials, its management is also varied. This is a systematic review from evidence-based studies until March 1st, 2020, covering an update on its clinical features and management. This study shows the multisystem involvement of COVID-19 with dominant respiratory features followed by the musculoskeletal, gastrointestinal system and others. The clinical features varied from asymptomatic to severe forms. Major causes of fatality were acute respiratory distress syndrome, shock, acute cardiac injury, acute kidney injury, rhabdomyolysis, and arrhythmia. Major modalities of management included supportive, antiviral and antibiotic therapy. There was no direct relationship between the specific treatment and the outcome.

    PMID: 34857376 DOI: 10.1016/j.jpedsurg.2021.10.029
    BACKGROUND: Increased intra-abdominal pressure (IAP) is seen in patients after congenital diaphragmatic hernia (CDH) repair owing to reduction of thoracic contents into the relatively smaller abdominal cavity. In infants, IAP ≥11 mmHg is considered intra-abdominal hypertension (IAH). We aim to determine the incidence of IAH and its relationship with duration of ventilatory support, and gastrointestinal function post CDH repair.

    METHODS: We prospectively recruited all neonates who had CDH repair in four hospitals in Malaysia from June 2018 to October 2020. Intra vesical pressure was used as a proxy for IAP and was measured for 5 consecutive days post surgery. The daily median value was used for analysis. We categorized IAP as <11 mmHg (no IAH), 11-15 mmHg (IAH), and >15 mmHg (severe IAH). Incidence of IAH, its effects on the duration of ventilatory support, and gastrointestinal function were studied.

    RESULTS: There were 24 neonates included in this study. They were operated between day 1 and 6 of life (median: 4 days old). IAH was detected within the first 3 days post surgery, with 83% occurring on day one. Those requiring ventilatory support for more than 3 days contributed the largest proportion of IAH (n = 17, 71%). There was strong correlation between days of IAH and duration of ventilation (p

    Clinical and pathological changes are described in groups of five goats pretreated with dexamethasone and then infected with a large dose of Pasteurella multocida B:2 (the cause of haemorrhagic septicaemia) by the intratracheal, subcutaneous or intranasal route (groups A, B and C, respectively). In group A, two goats died (on day 1 and 4 post-inoculation); in group B three died (days 2, 5 and 14); and in group C one died (day 20). The infecting organism was recovered from the four goats that died within < or =5 days. The major pulmonary lesions included acute pneumonia, congestion, oedema and hydrothorax. Subcutaneous oedema of the lower jaw and brisket, typically seen in cattle and buffalo, was absent in goats.

    Exposure to traffic air pollutant have shown a significant health effect on respiratory systems and decreased in lung function among traffic policemen. The main objective of this study was to determine the relationships between personal exposure levels to PM2.5 and respiratory health among traffic policemen working at Traffic Police Station in Kuala Lumpur and general duty policemen attached to Police Headquarters, Bukit Aman. A cross sectional comparative study was conducted among 50 traffic policemen from Traffic Police Station Kuala Lumpur and 50 general duty policemen from Police Headquarters Bukit Aman as comparative group. A purposive sampling method was used to select the respondents based on inclusive criteria such as age between 25 to 60 years, no history of respiratory disease and working not less than 3 years as traffic policemen. Questionnaire based on ATS (1978) was used to collect information on socio-demographic and respiratory symptoms. Spirometer (Spirolab II Model) was used to perform lung function tests. Personal Air Sampling Pump (Aircheck 52) was used to measure personal exposure level to PM2.5. The mean exposure level of PM2.5 among the traffic policemen was 22.33 ± 8.54μg/m³ compared to only 5.60 ± 4.29μg/m³ for comparative group. There was a significant difference in all lung function parameters between the exposed group and comparative group.From the finding, it shows that there was significant relationship between working duration (years) and lung function parameters among both exposed and comparative group. The result from this research shows that traffic policemen were determined as having lower lung function parameters due to their nature of work and the environment. Also, there was a significant association between exposure to fine particle (PM2.5) and lung function among the exposed group. Finding from this study indicated that exposure to elevated concentration level to traffic related air pollutant was the risk factors in the development of respiratory diseases as shown by the higher prevalence of respiratory symptoms and the reduction in lung function among traffic policemen.

    During a disaster, the rescuer must reach the disaster area within the fastest time with the help of navigation tools. However, there might be some obstacles during the night time that make the evacuation of the victims difficult especially due to the bad weather. Hence, an attempt to produce glow-in-the-dark emergency signage to ease the evacuation process and to enhance visibility during night time is necessary. In this present study, particular emphasis is given to investigate the characteristic of photo-luminescent (PL)powder applied with polyester resin as glow-in-the-dark emergency signage. Five samples of signage were fabricated with different percentage of PL powder, i.e. 20%, 40%. 60%, 80% and 100% and mixed with 150g polyester resin. Three types of luminance test were performed to check the workability of the samples. The tests are physical appearance, one-hours illuminance test and afterglow duration tests. The result showed that the maximum lux meter reading was recorded in Sample 5 with 6 lux luminosity and provided the longest glow duration of the sample before completely off after 12-hours. Results proved that the highest percentage of the PL powder content, the longer the afterglow duration will be achieved. It also noted that the polyester resin could be a good binder of PL powder for producing the glow-in-the-dark emergency signage.
