Abstract
Background Bronchial asthma is characterised by chronic inflammation of both large and small airways. Extra-fine formulation of inhaled corticosteroid (ICS) can achieve a higher peripheral lung deposition leading to improved asthma control. We investigated the effect of extra-fine and fine particle size inhaled ICS with airway resistance and severity of symptoms in asthmatic patients. Methods Prospective interventional study of outpatient asthmatics in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Subjects were grouped based on pre-existing inhalers; extra-fine and fine inhaled corticosteroid (ICS)/long acting beta agonist (LABA). Crossover was at week 7 and treatment regime continued for 7 weeks. Subjects were assessed at week 0, 6 and 13 using asthma control test (ACT) score, forced expiratory volume in 1 s (FEV1) and impulse oscillometry (IOS) Inhaler technique was assessed periodically. Results Thirty-four subjects were recruited. Median asthma duration was 20 years. Twenty subjects (58%) in fine ICS/LABA and 14 (42%) in extra-fine ICS/LABA group. Thirty-one subjects were analysed before crossver. There was a significant improvement of FEV1 in the extra-fine ICS/LABA group (1.7 ± 0.47 to 1.88 ± 0.5; p = 0.01). ACT score reduced significantly in extra-fine ICS/LABA group (23 ± 5 to 21 ± 4; p = 0.04) at week 0–6. Week 7–13 showed a significant improvement of ACT score (16.5 ± 3 to 20 ± 3; p = 0.01) and FEV1 (1.71 ± 0.96 to 1.81 ± 1.02: p = 0.01) in extra-fine ICS/LABA. There was no significant difference in (IOS) parameters between the groups. Conclusion There was an improvement of FEV1 and ACT score with extra-fine ICS/LABA with no benefit in airway resistance.

Abstract
Background Aerobika® oscillating positive expiratory pressure (OPEP) device promotes airway clearance in many respiratory diseases. However, studies have yet to focus on its effectiveness in improving small airway resistance via impulse oscillometry (IOS) measurement in COPD subjects. We aim to evaluate the improvement of small airway resistance (via IOS), lung function (spirometry), exercise capacity [via 6-min walking test (6MWT)], symptoms [COPD assessment test (CAT)] and severe exacerbation events among COPD subjects using Aerobika® OPEP. Methods This was a prospective, single-arm interventional study among COPD subjects with small airway disease. Subjects were instructed to use twice daily Aerobika® OPEP (10 min each session); for 24 weeks; as an additional to standard therapy. IOS, spirometry, 6MWT, CAT score and severe exacerbation events were evaluated at baseline, 12 weeks and 24 weeks. Results Fifty-three subjects completed the study. Aerobika® usage showed improvement of IOS parameters; e.g. measurement of airway resistance at 5 Hz (R5), cmH20/L/s, (12-week p = 0.008, 24-week p < 0.001), R5% predicted (12-week p = 0.007, 24-week p < 0.001) and small airway resistance (R5-R20), cmH20/L/s, (12-week p = 0.021, 24-week p < 0.001). There were improvement of lung function; e.g. FEV1, L (12-week p = 0.018, 24-week p = 0.001), FEV1% predicted (12-week p = 0.025, 24-week p = 0.001), FEF25-75, L (12-week p = 0.023, 24-week p = 0.002), and FEF25-75% predicted (12-week p = 0.024, 24-week p < 0.001). CAT score improved at 12 weeks (p < 0.001) and 24 weeks (p < 0.001). Subjects had improved exercise capacity (6MWT, metres) after 24 weeks (p = 0.016). However, there was no significant difference in severe exacerbation events 24 weeks before and after Aerobika® usage. Conclusion Aerobika® OPEP demonstrated significant improvement in small airway resistance as early as 12 weeks of usage, with sustained improvement at 24 weeks. Aerobika® OPEP administration had significantly improved lung function, 6MWT, and CAT scores over 24 weeks. There was no difference in severe exacerbation events.

Abstract
We report a 35-year-old woman who presented with dyspnoea and chest pain for 1 week. High-resolution computed tomography (HRCT) thorax revealed bilateral pneumothoraces with diffuse lung cysts. Bilateral intercostal chest tubes were inserted, and there was a persistent air leak (PAL) bilaterally. We performed an autologous blood patch pleurodesis (ABPP) for the left PAL. For the right PAL, she underwent a successful right video-assisted thoracic (VATS) surgery, wedge biopsy, and surgical pleurodesis. Histopathology examination confirmed the diagnosis of lymphangioleiomyomatosis (LAM). The left pneumothorax recurred. An indwelling pleural catheter (Rocket® IPC™; Rocket Medical plc; WASHINGTON) was inserted and the patient was discharged after 1 day with an atrium pneumostat (Pneumostat™; Atrium Medical Corporation, Hudson, NH, USA) chest drain valve. The patient was initiated on Sirolimus 2 mg daily. The left PAL resolved at 6 weeks. This case highlights the benefit of IPC with an ambulatory pneumothorax device in a patient with LAM with PAL.

Abstract
BACKGROUND Patient comfort during invasive and therapeutic procedures is important. The use of virtual reality (VR) devices during flexible bronchoscopy (FB) as a method of distraction to increase patient tolerability and improve satisfaction has not been investigated. We aim to assess the satisfaction and tolerability of participants undergoing FB with or without VR. METHODS This was a single-center, open-label study on patients undergoing bronchoscopy, randomized into the control and interventional (VR) groups. The control group received standard care during FB. The interventional group was given a VR device during FB showing nature videos with soothing instrumental music. Pain, breathlessness, and cough were evaluated using a 10 cm visual analogue scale administered before and after FB. Anxiety was assessed using the State-Trait Anxiety Inventory. Satisfaction questionnaire (5-point Likert scale) was given to participants post FB. RESULTS Eighty participants enrolled, 40 in each arm. Median (IQR) satisfaction score in the VR group was 5.0 (3.0-5.0), and in the control group was 4.0 (3.0-5.0); (p < 0.001). Breathlessness, cough, and anxiety post FB were significantly less severe in the interventional group (p = 0.042, p = 0.001, p < 0.001), but the pain was not significantly different (p = 0.290). CONCLUSION VR used during FB led to better participants' satisfaction and tolerability (breathlessness and cough). There was a significantly lower anxiety score in the VR group.

Abstract
Background Intrapleural fibrinolytic therapy (IPFT) is one of the treatment options for complex pleural effusion. In this study, the IPFT agent used was alteplase, a tissue plasminogen activator (t-PA). This study aims to determine the difference in the outcome of patients with complex pleural effusion between IPFT and surgery in terms of radiological improvement, inflammatory parameters, length of stay, and post-intervention complications.
Methods A retrospective review of patients with complex pleural effusion treated at Universiti Kebangsaan Malaysia Medical Center from January 2012 to August 2020 was performed. Patient demographics, chest imaging, drainage chart, inflammatory parameters, length of hospital stay, and post-intervention and outcome were analyzed. Results Fifty-eight patients were identified (surgical intervention, n = 18; 31% and IPFT, n = 40, 69%). The mean age was 51.7 ± 18.2 years. Indication for surgical intervention was pleural infection (n = 18; 100%), and MPE (n = 0). Indications for IPFT was pleural infection (n = 30; 75%) and MPE (n = 10; 25%). The dosages of t-PA were one to five doses of 2–50 mg. The baseline chest radiograph in the IPFT group was worse than in the surgical intervention group. (119.96 ± 56.05 vs. 78.19 ± 55.6; p = 0.029) At week 1, the radiological success rate for IPFT and surgical intervention were 27% and 20%, respectively, and at weeks 4–8, the success rate was 56% and 80% respectively. IPFT was associated with lesser complications; fever (17.5%), chest pain (10%), and non-life-threatening bleeding (5%). Conclusion IPFT was comparable to surgery in radiological outcome, inflammatory parameters, and length of stay with lesser reported complications.

Abstract
BACKGROUND Lung nodule management remains a challenge to clinicians, especially in endemic tuberculosis areas. Different guidelines are available with various recommendations; however, the suitability of these guidelines for the Asian population is still unclear. Our study described the prevalence of malignant lung nodules among nodules measuring 2-30 mm, the demographic and characteristics of lung nodules between benign and malignant groups, and the clinician's clinical practice in managing lung nodules. METHOD Retrospective review of lung nodules from the computed tomography archiving and communication system (PACS) database and clinical data from January 2019 to January 2022. The data was analysed by using chi square, mann whitney test and simple logistic regression. RESULTS There were 288 nodules measuring 2-30 mm identified; 49 nodules underwent biopsy. Twenty-seven (55%) biopsied nodules were malignant, (prevalence of 9.4%). Among the malignant lung nodules, 74% were adenocarcinoma (n = 20). The commonest benign nodules were granuloma n = 12 (55%). In nodules > 8 mm, the median age of malignant and benign was 72 ± 12 years and 66 ± 16 years, respectively (p = 0.024). There was a significant association of benign nodules (> 8 mm) in subjects with previous or concurrent tuberculosis (p = 0.008). Benign nodules are also associated with nodule size ≤ 8 mm, without spiculation (p < 0.001) and absence of emphysema (p = 0.007). The nodule size and the presence of spiculation are factors to make the clinicians proceed with tissue biopsy. Spiculated nodules and increased nodule size had 11 and 13 times higher chances of undergoing biopsy respectively (p < 0.001).) Previous history of tuberculosis had a 0.874 reduced risk of progression to malignant lung nodules (p = 0.013). These findings implied that these three factors are important risk factors for malignant lung nodules. There was no mortality association between benign and malignant. Using Brock's probability of malignancy, nodules ≤ 8 mm had a low probability of malignancy. CONCLUSION The prevalence of malignant lung nodules in our centre was comparatively lower than non-Asian countries. Older age, the presence of emphysema, and spiculation are associated with malignancy. Clinical judgment is of utmost importance in managing these patients. Fleishner guideline is still being used as a reference by our clinician.
