  1. Respiratory epithelium, production performance and behaviour of formaldehyde-exposed broiler chicks
    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.

  3. Survival and factors associated with mortality among infants with anorectal malformation: a population-based study from a middle-income country
    Mat Bah MN, Zahari N, Kasim AS, Mohamed Sharif NL
    Eur J Pediatr, 2024 Jan;183(1):271-279.

    Limited data on the survival of anorectal malformation (ARM) patients from lower- and middle-income countries is available. This retrospective population-based study from the State of Johor, Malaysia, determines the incidence, mortality rate, and survival of ARM patients and factors associated with mortality. Kaplan-Meier survival analysis was used to estimate the survival of ARM patients at 1, 5, and 10 years. In addition, multivariate Cox regression analysis was used to analyze mortality-related factors. There were 175 ARM patients among 803,850 live births, giving an overall ARM incidence of 2.2 (95% confidence interval [CI], 1.9 to 2.5) per 10,000 live births. The male-to-female ratio was 1.5:1. There were 122 (69%) non-isolated ARM, of which 41 were Trisomy-21 and 34 had VACTERL association. Seventy-three (42%) had congenital heart disease (CHD), with 38 severe and 35 non-severe CHD. Overall, 33 (19%) patients died, with a median age of death of 5.7 months (interquartile range (IQR) 25 days to 11.2 months). The overall estimated 1-, 5-, and 10-year survival rate for ARM patients was 82% (95% CI, 76-89%), 77% (95% CI, 70-84%), and 77% (95% CI, 70-84%), respectively. Univariate analysis shows that non-isolated ARM, VACTERL association, and severe CHD were associated with mortality. However, only severe CHD is the independent factor associated with mortality, with a hazard ratio of 4.0 (95% CI, 1.9-8.4).  Conclusion: CHD is common among ARM patients, and one in five ARM patients had a severe cardiac defect, significantly affecting their survival. What is Known: • VACTERL association and congenital heart disease are common in patient with anorectal malformation. • Low birth weight and prematurity are associated with a lower rate of survival. What is New: • Congenital heart disease is common in ARM patients in a middle-income country. • Severe congenital heart disease plays a significant role in the survival of patients with an anorectal malformation in lower- and middle-income countries.

  5. Induced expression of the antimicrobial peptide melittin inhibits experimental infection by Mycoplasma gallisepticum in chickens
    Lazarev VN, Stipkovits L, Biro J, Miklodi D, Shkarupeta MM, Titova GA, et al.
    Microbes Infect., 2004 May;6(6):536-41.
    PMID: 15158186
    The in vivo action of the antimicrobial peptide melittin, expressed from a recombinant plasmid vector, on chickens experimentally infected with Mycoplasma gallisepticum was studied. The plasmid vector pBI/mel2/rtTA includes the melittin gene under the control of an inducible tetracycline-dependent human cytomegalovirus promoter and the gene coding for the trans-activation protein rtTA. Aerosol administration of the vector, followed by infecting the chickens with M. gallisepticum 1226, is shown to inhibit development of infection. The inhibitory action was confirmed by a complex of clinical, pathomorphological, histological and serological studies, and also by comparing the M. gallisepticum reisolation frequency from the respiratory tract and internal organs. The data suggest that plasmid vectors expressing genes of antimicrobial peptides can be considered as potential agents for the prevention and treatment of mycoplasma infections in poultry farming.

  6. Bronchodilator effects of Lignosus rhinocerotis extract on rat isolated airways is linked to the blockage of calcium entry
    Lee MK, Lim KH, Millns P, Mohankumar SK, Ng ST, Tan CS, et al.
    Phytomedicine, 2018 Mar 15;42:172-179.
    PMID: 29655683 DOI: 10.1016/j.phymed.2018.03.025
    BACKGROUND: Lignosus rhinocerotis (Cooke) Ryvarden is a popular medicinal mushroom used for centuries in Southeast Asia to treat asthma and chronic cough. The present study aimed to investigate the effect of this mushroom on airways patency.

    MATERIALS AND METHODS: The composition of L. rhinocerotis TM02 cultivar was analyzed. Organ bath experiment was employed to study the bronchodilator effect of Lignosus rhinocerotis cold water extract (CWE) on rat isolated airways. Trachea and bronchus were removed from male Sprague-Dawley rats, cut into rings of 2 mm, pre-contracted with carbachol before adding CWE into the bath in increasing concentrations. To investigate the influence of incubation time, tissues were exposed to intervals of 5, 15 and 30 min between CWE concentrations after pre-contraction with carbachol in subsequent protocol. Next, tissues were pre-incubated with CWE before the addition of different contractile agents, carbachol and 5-hydroxytrptamine (5-HT). The bronchodilator effect of CWE was compared with salmeterol and ipratropium. In order to uncover the mechanism of action of CWE, the role of beta-adrenoceptor, potassium and calcium channels was investigated.

    RESULTS: Composition analysis of TM02 cultivar revealed the presence of β-glucans and derivatives of adenosine. The extract fully relaxed the trachea at 3.75 mg/ml (p trachea and bronchus but at a longer incubation interval between concentrations. CWE pre-incubation significantly reduced the maximum responses of carbachol-induced contractions (in both trachea, p = 0.0012 and bronchus, p = 0.001), and 5-HT-induced contractions (in trachea, p = 0.0048 and bronchus, p = 0.0014). Ipratropium has demonstrated a significant relaxation effect in both trachea (p = 0.0004) and bronchus (p = 0.0031), whereas salmeterol has only affected the bronchus (p = 0.0104). The involvement of β2-adrenoceptor and potassium channel in CWE-mediated airway relaxation is ruled out, but the bronchodilator effect was unequivocally affected by influx of calcium.

    CONCLUSIONS: The bronchodilator effect of L. rhinocerotis on airways is mediated by calcium signalling pathway downstream of Gαq-coupled protein receptors. The airway relaxation effect is both concentration- and incubation time-dependent. Our findings provide unequivocal evidence to support its traditional use to relieve asthma and cough.

    This study provides a comparative analysis of the effects of pre-slaughter penetrative and non-penetrative stunning and post-slaughter stunning on meat quality attributes in longissimus lumborum (LL) and semitendinosus (ST) muscles in heifers. Ten animals were assigned to each of four treatment groups: i) animals were subjected to conventional Halal slaughter (a clean incision through the structures at the front of the upper neck - the trachea, oesophagus, carotid arteries and jugular veins) and post-cut penetrating mechanical stun within 10 to 20 s of the neck cut (Unstunned; US); ii) high power non-penetrating mechanical stunning followed by the neck cut (HPNP); iii) low power non-penetrating mechanical stunning followed by the neck cut (LPNP); and iv) penetrative stunning using a captive bolt pistol followed by the neck cut (P). For each carcass, muscle samples were removed within 45 min of slaughter, portioned and analysed for pH, cooking loss, water holding capacity (WHC), tenderness (WBS), lipid oxidation (TBARS) and color, over a two week storage period. Stunning did not affect pH and cooking loss. Significant differences in water holding capacity, tenderness, lipid oxidation and color were present at different storage time points. HPNP stunning resulted in lower WHC and color values, particularly lightness (L*), higher TBARS values and peak force values compared with those stunned using LPNP, P and US. These adverse effects on quality were mostly encountered in the ST muscle. In conclusion, the meat quality achieved using P, LPNP and US treatments was comparable, and no treatment stood out as considerably better than another.

  9. Fulltext Molecular and antimicrobial analyses of non-classical Bordetella isolated from a laboratory mouse
    Loong SK, Mahfodz NH, Wali HA, Talib SA, Nasrah SN, Wong PF, et al.
    J Vet Med Sci, 2016 May 3;78(4):715-7.
    PMID: 26782013 DOI: 10.1292/jvms.15-0472
    Accurate identification and separation of non-classical Bordetella species is very difficult. These species have been implicated in animal infections. B. hinzii, a non-classical Bordetella, has been isolated from mice in experimental facilities recently. We isolated and characterized one non-classical Bordetella isolate from the trachea and lung of an ICR mouse. Isolate BH370 was initially identified as B. hinzii by 16S ribosomal DNA and ompA sequencing. Additionally, isolate BH370 also displayed antimicrobial sensitivity profiles similar to B. hinzii. However, analyses of nrdA sequences determined its identity as Bordetella genogroup 16. The isolation of BH370 from a healthy mouse suggests the possibility of it being a commensal. The nrdA gene was demonstrated to possess greater phylogenetic resolution as compared with 16S ribosomal DNA and ompA for the discrimination of non-classical Bordetella species.

    The upper airway is a crucial structure. It becomes a grave problem should it be narrowed. Several methods
    of treatment were rendered for patients with laryngotracheal stenosis. We share our experience with the
    combination total intravenous anaesthesia and apneic pause technique with or without steroid injection.
    Four cases of laryngotracheal stenosis were observed in Hospital Ampang: two adult and two paediatric
    cases. Age, gender, causative factor, stenosis segment length, grade or severity were observed before and
    after dilatation, number of dilatation were observed and compared. The outcome measures are
    decannulation and avoidance of tracheostomy. All cases had improvement of symptoms. Half or 50% of the
    patient required repeated balloon dilatations. The paediatric cases successfully avoided tracheostomy while
    the adult cases successfully decannulated with no complication from the procedure. Balloon dilatation by
    total intravenous anaesthesia coupled with apneic method is a safe and effective method of treatment for
    the narrowed airway.

    Slaughtering is the first step in meat processing. It involves killing an animal for the production of meat. Effectiveness of slaughter is determined by the amount of blood removed from the animal. This study aimed to compare the chemical changes and microbiological quality of broiler chicken meat slaughtered by Halal and Non-Halal slaughter methods during refrigerated storage. A total of sixty (60) broiler chickens were slaughtered by: i) Neck cutting (NC) - by severing the jugular veins, carotid arteries, trachea and the oesophagus according to the Islamic ritual method of slaughter and (ii) Neck poking (NP) - by poking the neck of the bird with a sharp object. Residual blood was quantified by measuring the haem iron content in the breast meat samples. Storage stability of chicken meat was evaluated by measuring the extent of lipid oxidation determined by thiobarbituric acid reactive substances (TBARS) and by assessing the microbiological quality of the meat. Haem iron content decreased significantly (P0.05) on chicken meat lipid oxidation at 1, 3, and 9 day of storage at 4oC. However, at 5 and 7 day of storage, significant differences (P

    Mucoepidermoid carcinoma (MEC) is a rare tumour of the trachea accounting for up to 0.2% of reported primary lung malignancy. We report a case of a 54-year-old man, ex-smoker, whose presentation mimicked adult onset asthma with cough and wheezing, which did not respond to conventional treatment. He had occasional haemoptysis and weight loss in which CT scan performed for malignancy screening showed a protruding mass in the distal trachea causing endobronchial obstruction. Bronchoscopic intervention was performed to relieve the obstruction that resulted in resolution of asthmatic symptoms. Histological diagnosis confirmed MEC. This case emphasised the importance of a high index of suspicion in an unusual presentation of a common disease and the pivotal role of bronchoscopic intervention in malignant central airway obstruction.

    We report a 55-year old lady with the presentation of stridor and type II respiratory failure requiring tracheal intubation. She had right Horner’s syndrome associated with pleural effusion. Her chest radiograph revealed right upper zone lobulated opacities and therefore right Pancoast tumor was the initial diagnosis. However, her CECT thorax revealed a huge right subclavian artery pseudoaneurysm with severe tracheal compression. This rare condition imposed a significant diagnostic as well as therapeutic challenge. Vascular surgery is the definitive treatment but it is associated with high risks. The exact role of rigid bronchoscopy for airway stenting is unknown due to limited evidence available. Indeed, this form of central airway obstruction may benefit from temporary tracheal stenting whilst the surgical repair of the lesion is planned. It may facilitate early weaning and allows less complicated airway control.

    MyJurnal
    Foreign body aspiration is commonly described in infants and children. However, recently, a new
    high-risk group was identified among young women, especially those from the Muslim population
    who wear the traditional hair scarf. This is due to the habit of holding the scarf pin in between the
    lips to free hands to adjust the scarf more easily. Talking, laughing, or coughing while fixing the
    scarf may result in inadvertent inhalation of the pin into the tracheobronchial tree. We present a
    case of scarf pin inhalation and the challenges encountered in managing this patient during the
    successful removal of the pin via flexible bronchoscopy under fluoroscopy guidance. This particular
    case was technically challenging for us as the sharp tip of the needle was pointing upward and
    piercing the bronchial mucosa.

    Mycoplasma imitans (Mim) has been isolated from ducks, geese and partridges, and is closely related to Mycoplasma gallisepticum (Mg). The pathogenicity of Mim for chicks was investigated in single and mixed infections with infectious bronchitis virus (IBV) by giving IBV strain M41 at 1-day-old and Mim 2 days later. Single infections with IBV or Mim were also performed. No clinical signs or gross lesions were seen in chicks infected with Mim or uninfected control chicks, but they were seen in the other two groups. Clinical scores were consistently higher in birds with mixed infections than those infected with IBV alone, and were significantly higher (P < 0.05) between days 7 and 14. More birds developed sinusitis, tracheitis and airsacculitis (with greater severity) in the mixed than the single IBV infections. Mim was recovered more frequently and in greater numbers from the respiratory tract of birds with mixed than single infections. It was recovered from the lower trachea, air sacs and lungs only in mixed infections. Seroconversion to Mim occurred by day 14 in mixed infections, but not until day 21 in single infections. It appears that Mim can act synergistically with IBV in young chickens in a similar manner to Mg, although Mg may act as a primary pathogen under some circumstances.

    Sarcomas usually frequented in the head and neck region of young adults. Trachea is a rare site, and due to scarce clinical data, its clinical outcome is unclear. We reported a case of 60-year old patient presented with progressive worsening shortness of breath, cough, and progressive worsening dysphagia. Computer tomography scan revealed extensive 2 lobulated soft tissue lesions within and surrounding the trachea at the T4 level. Rigid bronchoscopy with mass cryo-debulking was performed and ultimately synovial sarcoma was diagnosed. Shortness of breath was com- pletely relieved post-procedure.

    Manual work is associated with increased lung cancer risk possibly because of increased exposure to occupational and other carcinogens, reduced use of health care services and/or a less healthy lifestyle. The aim of this study was to examine whether the association between manual work and lung cancer risk has changed over time. Three separate retrospective studies were carried out over a 10-year period (1996-1997, 1998-2000 and 2003-2005) in patients attending a bronchoscopy clinic to investigate lung cancer risk in an area of Manchester characterised by high deprivation and unemployment. Cases (n=321) were patients newly diagnosed with a tumour of the lung, trachea or bronchus and controls (n=542) were patients free of tumours at the time of, and prior to, examination. Patients were interviewed using the same structured questionnaire for associations between risk factors and lung cancer examined. The study population in all three studies was similar with little difference in smoking history. In each study smoking was associated with lung cancer risk. Lung cancer risk was higher in manual workers (compared to managers and other professionals) in the first (OR 2.50, 95% CI 1.20 – 5.05) and second study (OR 2.73, 95% CI 0.97 – 7.70) but not the third (OR 0.97, 95% CI 0.58 – 1.61). However, the summary odds ratio (meta-OR) for lung cancer in manual worker was 1.81 (95% 1.75 – 1.87) after controlling for sex, age and smoking. This study suggested that even after taking into account known occupational and environmental causes of cancer, there was a residual cancer risk associated with manual work, high risk working populations of lung cancer. However this appears to have attenuated recently for as yet unknown reasons.

    There are many inherent challenges in the evaluation and management of children with laryngotracheal disorders, and it differs widely from one institution to another. The main challenges include access to suitable equipment, fully trained surgeon and, cooperation with the anesthetist and pediatrician. Material & Methods: The aim of the study was to analyze the pediatric laryngotracheal cases undergoing endoscopic examination in Hospital Universiti Sains Malaysia. A retrospective review of 73 cases undergoing microlaryngoscopy and bronchoscopy from 2004 to 2008 was done. Results: Laryngomalacia was the commonest diagnosis. The majority of the cases (45.2 %) were referred because of noisy respiration. Other reasons for referral were foreign body inhalation, unresolved lung disease, failed extubation, examination prior to decannulation and hoarseness. Conclusion: Management of pediatric laryngotracheal cases were varied and tailored to each problem. The endoscopic examination must be meticulous. The management include observation, medical treatment, closed (endoscopic)
    techniques and open surgery.

    Vet World, 2017 May;10(5):542-548.
    PMID: 28620260 DOI: 10.14202/vetworld.2017.542-548
    AIM: Genotype VII Newcastle disease virus (NDV) is the most predominant NDV strains that circulating in Malaysia; thus, this study was aimed to determine the susceptibility of Japanese quails toward genotype VII NDV. Clinical signs, gross pathological lesions of organs, positive detection of virus in organs and cloacal swabs, as well as the expression of the antibody titer, were used as parameters to assess the susceptibility of Japanese quails following infection of genotype VII NDV.

    MATERIALS AND METHODS: About 20 quails were divided into three groups (n=8 for Groups A and B; n=4 for the control group). The quails in the Groups A and B were infected via intraocular route with 0.03 ml of 103.5 ELD50 and 107.0 ELD50 of NDV strain IBS 002, respectively, while the control group received 1× phosphate-buffered saline. Cloacal swabs and necropsy were taken on day 7 post-infection for all quails were subjected to one-step reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) for detection of virus and examination for gross pathological lesion, respectively. Blood serums of infected quails were taken on day 10, 14, and 21 post-day infections and were subjected for hemagglutination inhibition (HI) assay.

    RESULTS: Depression and ruffled feathers, trachea rales, leg paralysis, and torticollis were shown in some of the quails in both infected groups. Based on statistical analysis, there was no significant difference (p>0.05) in clinical signs between the infected groups. The results for RT-qPCR were found to be negative for all groups, and no gross pathological lesions of organs observed for quails in both infected groups. Trachea, proventriculus, and cecal tonsil were taken for the detection of NDV by RT-qPCR, and some of the organ samples showed positive detection of virus in both infected groups. HI assay showed an increase in mean titers of antibody across time and between infected groups.

    CONCLUSION: In summary, Japanese quails are susceptible to genotype VII NDV based on parameters assessed.
