RESUMO
To differentiate cavitary lung lesions caused by melioidosis and tuberculosis is challenging, especially in endemic countries. A study with a matched-sampling method (16 cavitary pulmonary melioidosis vs. 16 cavitary pulmonary tuberculosis) showed characteristics of bacterial infection more obvious and severe in the melioidosis patients, which were useful to distinguish two conditions.

BACKGROUND: Stepping down treatment for well-controlled mild asthma is challenging to clinicians. The step-down strategy using regularly-intermittent low-dose inhaled corticosteroid has been applied at the University Medical Center (UMC) of Ho Chi Minh City, called as "UMC" approach. OBJECTIVE: This study aimed to evaluate the efficiency of UMC step-down strategy in well- controlled mild asthma. METHODS: A real-world retrospective descriptive study was conducted at UMC from 2009 to 2018. All asthmatic patients (age ≥ 12) who received step-down therapy using this UMC approach were evaluated. RESULTS: Among 2,072 asthma patients to be treated with UMC step-down strategy, only 112 subjects were eligible. The median age was 38.5 years and female was 62.5%. Most patients at their initial presentation were indicated step 4 treatment (87.5%). The controller medications before initiation of UMC treatment included fluticasone propionate 125 µg once-daily, salmeterol/fluticasone propionate 25/125 µg once-daily, and formoterol/budesonide 4.5/160 µg once-daily. After being treated with the UMC approach, the rates of well-controlled asthma ranged from 67.6% to 91.1%. During 1 year with UMC treatment, pulmonary function remained stable and only 7 subjects (6.3%) developed exacerbation. CONCLUSION: The UMC step-down treatment for well-controlled mild asthma was relatively efficient in maintaining asthma control, stabilization of pulmonary function, and reducing risk of severe exacerbation.
RESUMO
Dysphagia is the most common symptom in symptomatic patients with aberrant right subclavian artery (ARSA) and also the risk factor of aspiration, especially in elderly patients. We presented an 84 year-old female patient with dysphagia induced by the compression of ARSA to the adjacent structures. Recurrent pneumonia and bibasilar bronchiectasis were recorded in the association with ARSA. We concluded that elderly patient with ARSA should be evaluated the pulmonary complications such as aspiration pneumonia and bronchiectasis.
