    The main morbid anatomical features of the 176 lung, the 2 tracheal, and the 13 laryngeal cancers seen in the 22,997 post-mortems performed by the University and Government Departments of Pathology, Singapore, from 1948-58 inclusive, are described, and are seen to be as elsewhere. About one-tenth of all cancers admitted to hospital, and of all cancers registered by the Registrar-General (Singapore) from 1954-58 inclusive were in the lung. In 15 per cent of all post-mortems on persons with malignant disease, the primary tumour was of pulmonary origin. The crude death rate for cancer of the lung in Singapore for 1954-58 inclusive was 0-065 per 1000 living per annum. More cases of lung cancer are seen before the age of 40 than in the West. The consumption of tobacco in Singapore is noted to be 3-7 lb. (1.7 kg) per person per annum. A portion of the literature on cancer of the lung in South-East Asia and in China is discussed. I wish to thank Professor R. Kirk for kind help and encouragement, my colleagues of the Government and University Departments of Pathology for access to their post-mortem notes and records, Mr. E. J. Phillips and Mr. S. C. Chua of the Department of Statistics, Singapore, and Mr. Lee of the Customs Department, Singapore, for various data, Mr. Ti Teow See for Fig. 1, and Mr. P. A. Samuel who typed the script. This communication forms part of a thesis for the degree of Ph.D. (Malaya). © 1960, The British Empire Cancer Campaign for Research. All rights reserved.

    A retrospective survey was carried out in a neonatal unit to identify babies who required oxygen for more than the first 28 days of life and to determine the cause of their oxygen dependency. A total of 9173 neonates were admitted over a three year period. Approximately 750 were ventilated. Fifteen required oxygen for more than the first 28 days. Ten (67%) of these were due to bronchopulmonary dysplasia. 2 had upper airway complications of mechanical ventilation, one had recurrent apnoea, one had recurrent pneumonia, and one who did not require ventilation had chronic oxygen dependency of unknown cause. Bronchopulmonary dysplasia was the commonest cause of chronic oxygen dependency. The incidence was 1.5% of ventilated babies.

    A study on 30 asthmatic children was conducted in Kuala Lumpur. The objective of this study was to study the relationship between respirable particulate (PM10), sulphur dioxide, ozone and various meteorological factors such as humidity, level ofrainfall and temperature with asthma attacks. This study was conducted from 1st September to 31 December 1994. Patients were selected from the Paediatric Unit, Kuala Lumpur Hospital. Questionnaires were used to obtain information from their parents on the history and severity ofasthmatic attacks ofthese patients. Questionnaires were also used to determine if the indoor sources contributed to the attack. Diary cards were used to collect information on the frequency of asthmatic attacks. Each patient's progress was followed through every week during the study period and the attacks were recorded. The data on air quality on the PM10, sulphur dioxide, nitrogen dioxide, carbon monoxide and ozone were collected hourly using the microcomputer system of air monitoring unit from the Universiti Pertanian Malaysia air quality monitoring station located at the City Hall, Kuala Lumpur. The meteorological parameters such as temperature, relative humidity and rain-fall levels were also monitored daily. The asthmatic attack percentage was obtained by dividing the number of attacks in a day with the total number of sample and multiplying by a hundred. Statistical tests indicated that there was a significant correlation between asthmatic attacks and the PM10 concentrations (r=0.73), nitrogen dioxide (r=0.57) and.carbon monoxide (r=0.53) throughout the study period. During the haze episode, more significant correlations between asthmatic attacks, PM10 concentra-tions (0.86), carbon monoxide (0.79) and nitrogen oxide (0.53) were found. Multiple regression statistical test showed that PM10 had the greatest influence on the asthmatic attack rate. The minute respirable particulate which entered the respiratory system of the asthmatics triggered attacks on these patients.

    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.

    A study to determine the immunoglobulin and cellular responses in the respiratory tract of goats following intranasal exposures to formalin-killed Pasteurella haemolytica A2 was carried out. Forty-two goats were divided into two groups. Goats in Group 1 were subjected to double intranasal exposures to formalin-killed P. haemolytica A2 while goats in Group 2 were the unexposed control. Prior to and at weekly intervals post-exposure, three goats from each group were killed, serum samples were collected while the lungs were flushed with 50 ml normal saline before the right apical lobes were fixed in 10% buffered formalin. Both serum and lung lavage fluid were subjected to enzyme-linked immunosorbent assay (ELISA) to determine the levels of IgA, IgM and IgG while the formalin-fixed tissues were examined histologically. IgA levels in the lung lavage fluid increased rapidly to reach a significantly (p < 0.05) high level as early as Week 2 post-exposure and remained significantly (p < 0.05) high throughout the study period. The IgM levels increased at an intermediate rate to reach a significantly (p < 0.05) high level at Week 3 post-exposure before they decreased to an insignificant (p > 0.05) level the following week and the weeks thereafter. IgG levels increased gradually and only reached a significantly (p < 0.01) high level at Weeks 5 and 6 of the study. The size of the bronchus-associated lymphoid tissue (BALT) and the number of lymphocytes in BALT increased significantly from Week 2 and remained high thereafter. However, differences in the numbers of BALT were insignificant (p > 0.05) initially before becoming significantly (p < 0.05) high at Weeks 5 and 6. The BALT responses were parallel to those of imunoglobulins in the lung lavage fluid.

    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.

    A paramyxovirus virus termed Nipah virus has been identified as the etiologic agent of an outbreak of severe encephalitis in people with close contact exposure to pigs in Malaysia and Singapore. The outbreak was first noted in late September 1998 and by mid-June 1999, more than 265 encephalitis cases, including 105 deaths, had been reported in Malaysia, and 11 cases of encephalitis or respiratory illness with one death had been reported in Singapore. Electron microscopic, serologic, and genetic studies indicate that this virus belongs to the family Paramyxoviridae and is most closely related to the recently discovered Hendra virus. We suggest that these two viruses are representative of a new genus within the family Paramyxoviridae. Like Hendra virus, Nipah virus is unusual among the paramyxoviruses in its ability to infect and cause potentially fatal disease in a number of host species, including humans.

    This study was conducted to determine the patterns of disease and treatment at two disaster sites. Studies prior to this have shown that all natural disasters are unique in that each affected region of the world have different social, economic and health backgrounds. However, similarities exist among the health effects of different disasters which if recognized can ensure that health and emergency medical relief and limited resources are well managed. This study found that although Aceh and Balakot were two totally different areas with reference to locality and climate it was noticed that the patterns of disease two months post disaster are similar the commonest being respiratory conditions followed by musculoskeletal conditions and gastrointestinal conditions. For the treatment patterns it was observed that the two areas prescribed almost similar, types of medicine mainly for gastrointestinal and respiratory systems. However in Aceh, there were more skin treatment and in Balakot there was more usage of musculoskeletal drugs.

    Cystic Fibrosis (CF) is a life-threatening inherited disease that particularly affects the airways and digestive systems, which is caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. CF is considered as the most common autosomal recessive disorder in the Caucasian population. However, the prevalence of this disease amongst Asians is considered to be low, hence the lack of awareness of this disease amongst geneticists and physicians in Malaysia. This review will describe the features of CF, its molecular genetics, the current classification of CFTR mutation classes, the genotype-phenotype correlations, the effects of modifier genes, and the discourse of the disease pathogenesis, in the hope of raising public awareness of the condition and ultimately to improve the clinical and social care of those affected by CF in Malaysia.

    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.

    Normal tracheal mucociliary clearance is the key to maintaining the health and defense of respiratory airway. Therefore the present of cilia and mucous blanket are important for tracheal epithelium to function effectively. In the present study, we prepared a tissue engineered respiratory epithelium construct (TEREC) made of autologous respiratory epithelium cells, fibroblast and fibrin from sheep owns blood which replaced a created tracheal mucosal defect. Scanning electron microscopy (SEM) showed encouraging result where immature cilia were present on the surface of TEREC. This result indicates that engineered respiratory epithelium was able to function as normal tissue.

    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.

    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.

    We report a case of sudden hypoxaemia after intubation in a patient who had smoked a few hours prior to a surgical procedure. The cause of his desaturation was not related to bronchial secretions, bronchospasm or obstruction of the upper airways but most likely due to reduced oxygen saturation in the body prior to surgery. We managed to secure the airway and prevent prolonged desaturation by instituting remedial measures. Our conclusion is that cessation of smoking is very important and need to be emphasized in all patients having surgery under general anaesthesia. This applies to emergency cases as well.
