“…Hence, it was stated that when this ratio is used for the quantitative analysis of pulmonary and cardiovascular disease, the influence of age should be considered. 26 However, although the subject and control groups in the present study were not homogeneous in terms of age and gender distribution, there was no significant relation of bronchial wall thickness measurements to age and gender both in the subject and control groups. Hence, our findings seem to be free of the possible compromising influences of age and gender disparity.…”

INTRODUCTION:This study aims to evaluate bronchial thickness via thorax high-resolution computed tomography (HRCT) in subjects with mild intermittent asthma in comparison with healthy control subjects. METHODS: A total of 37 out-patients (mean ؎ SD age ‫؍‬ 36.7 years (9.7 years); 54.8% males) with mild intermittent asthma and 13 healthy control subjects (mean ؎ SD age ‫؍‬ 25.0 years (2.9 years); 61.5% males) were included in this case control study. , P ‫؍‬ .046) were significantly higher in subjects than control subjects. No significant correlation of overall and subsegmental T/D and WA% values to age in both groups, and to asthma duration in subjects. CONCLUSION: Our findings revealed an increase in bronchial wall thickness in peripheral airways in subjects with mild intermittent asthma regardless of the duration of asthma. This may indicate a need to also administer anti-inflammatory or bronchodilator therapy, which is effective in peripheral airways during the early period of the disease.

“…Given the significant alterations in bronchial wall thickness associated with smoking, 26 exposure to environmental pollutants, 28 and the presence of OSA, 29 it is worth noting that our study population of subjects with mild asthma was composed of nonsmoker individuals without OSA and a history of exposure to environmental pollutants.…”

“…In particular, the key diagnostic criterion of bronchiectasis is increased bronchoarterial ratio, which is clearly influenced by age (r=0·77, p<0·0001). 54 Also the sensitivity of determining bronchiectasis radiologically is dependent upon the modality used as scans obtained on a multi-detector CT scan are more sensitive than those from a HRCT scan. 55 Thus in children, the term CSLD is used to describe a diagnosis where there are clinical symptoms of BE without HRCT confirmation.…”

A c c e p t e d M a n u s c r i p t 2 EDUCATIONAL AIMSThe reader will be able to:• Discuss the common respiratory problems encountered by indigenous children.• Appreciate the similarities and differences in the aetiology, associations and management of these common respiratory problems.• Understand the many facets that impact on the clinical outcomes of common respiratory conditions affecting indigenous children.• Discuss potential intervention targets that can reduce the morbidity and mortality of respiratory diseases in indigenous children. Page 3 of 27A c c e p t e d M a n u s c r i p t 3 SUMMARY Children in indigenous populations have substantially higher respiratory morbidity than nonindigenous children. Indigenous children have more frequent respiratory infections that are, more severe and, associated with long-term sequelae. Post-infectious sequelae such as chronic suppurative lung disease and bronchiectasis are especially prevalent among indigenous groups and have lifelong impact on lung function. Also, although estimates of asthma prevalence among indigenous children are similar to non-indigenous groups the morbidity of asthma is higher in indigenous children. To reduce the morbidity of respiratory illness, best-practice medicine is essential in addition to improving socio-economic factors, (eg household crowding), tobacco smoke exposure, and access to health care and illness prevention programs that likely contribute to these issues. Although each indigenous group may have unique health beliefs and interfaces with modern health care, a culturally sensitive and community-based comprehensive care system of preventive and long term care can improve outcomes for all these conditions. This article focuses on common respiratory conditions encountered by indigenous children living in affluent countries where data is available.

“…Matsuoka et al [27] showed a significant relationship between aging and the ratio of the diameter of the bronchus to the accompanying artery (bronchoarterial ratio). This was explained by relative hypoxemia existing in an aged cohort which caused vasoconstriction and (relative) bronchial dilation, effects which are seen among populations living at high altitude.…”

Since aspects of demographic transition have become an essential part of socioeconomic, medical and health-care research in the last decades, it is vital for the radiologist to discriminate between normal ageing related effects and abnormal imaging findings in the elderly. This article reviews functional and structural aspects of the ageing lung and focuses on typical ageing related radiological patterns. Key points: ??The physiological aging process of the thoracic organs shows typical structural and functional aspects. ??Mild interstitial fibrosis and focal parenchymal abnormalities like septal thickening can be diagnosed frequently ? whereas a clinical correlate is often lacking. ??With increasing patient age, the influence by various intrinsic and extrinsic factors (including comorbidities of the patient, and drug inhalation toxicants) also increases. ??A growing spectrum of imaging techniques (including functional cardiopulmonary MRI, MRI spectroscopy, hybrid-techniques) is confronted by rare empiric data in the very old people (aging 80 years and older).
