A Retrospective Study Evaluating Asthma Control in Patients on Fluticasone Propionate/Salmeterol Proactive Regular Dosing with a History of Uncontrolled Asthma.

Introduction: The MERIT study in Malaysia is a real-world retrospective, observational, multicenter study that evaluated asthma control in patients with uncontrolled asthma who were switched from as-needed (pro re nata [PRN]) budesonide/formoterol or inhaled corticosteroid (ICS) whenever a short-acting beta-agonist (SABA) was taken, to proactive regular dosing of fluticasone propionate/salmeterol (FP/SAL PRD).

Methods: Data from the medical records of patients who were stepped up to FP/SAL PRD were extracted retrospectively at baseline and follow-up (between 3 and 6 months after stepping up to FP/SAL PRD). The primary endpoint was the percentage of patients with improvement in asthma control assessed via the Asthma Control Test (ACT).

Re-expansion pulmonary oedema: two case reports and review of the current literature.

Re-expansion pulmonary oedema (RPE) is an uncommon complication that occurs when a collapsed lung suddenly re-expands, resulting in an osmotic shift of fluid from the blood vessels into the air spaces within the lungs. This condition can develop following thoracocentesis or intercostal chest drainage. We report two cases of RPE that developed after varying volumes of pleural drainage and at different times.

National expert consensus on short-acting beta-agonist overreliance in asthma care in Malaysia.

Objective: Inappropriate use of short-acting beta2-agonists (SABA) in asthma has been associated with undesired outcomes. This national expert consensus was developed to increase awareness of SABA overuse and provide recommendations on the ways to eliminate SABA overprescription and overreliance in Malaysia.

Data Sources: This expert consensus was developed by searching the PubMed database, using index terms to identify SABA overuse-related burden and recommendations made in asthma guidelines.

The outcome of 12-week corticosteroid therapy in COVID-19-related diffuse interstitial lung abnormalities.

Introduction: The efficacy of long-course corticosteroid therapy in treating COVID-19-related diffuse interstitial lung abnormalities (DILA) needs to be better understood. We aimed to investigate the benefits of 12-week corticosteroid treatment in COVID-19-related DILA by evaluating computed tomography (CT) lung severity scores.

Materials And Methods: This retrospective, single-centre observational study included patients aged 18 years or older admitted with moderate to severe COVID-19 pneumonia who received 12 weeks of oral prednisolone between January 2021 and December 2021.

Recurrent bilateral idiopathic chylothorax: a therapeutic challenge.

Chylothorax is a rare condition caused by pleural effusion resulting from thoracic duct injury. Recurrent chylothorax is often resistant to conservative treatment and presents a clinical conundrum in its management. Here, we report a compelling case of recurrent chylothorax that persisted despite the administration of total parenteral nutrition, octreotide and thoracic duct embolisation.

Combined intrapleural alteplase and DNase therapy in complicated pleural infection arising from postsurgery oesophageal leak.

Managing a complicated pleural infection related to postsurgery can pose a clinical challenge, especially when initial interventions such as intercostal chest drain and antibiotics prove ineffective. We describe a man in his mid-60s who developed a recurrence of exudative pleural effusion caused by an oesophageal leak following laparoscopic total gastrectomy with Roux-y oesophagojejunostomy for gastric adenocarcinoma. Surgical repairs and oesophageal stenting were performed to address the oesophageal leak.

Impact of Aerobika oscillating positive expiratory pressure in improving small airway resistance, lung function, symptoms and exercise capacity in chronic obstructive pulmonary disease.

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 impulse oscillometry (IOS) measurement in COPD subjects. We aim to evaluate the improvement of small airway resistance ( IOS), lung function (spirometry), exercise capacity [ 6-min walking test (6MWT)], symptoms [COPD assessment test (CAT)] and severe exacerbation events among COPD subjects using Aerobika OPEP.

Short-acting β-agonist prescription patterns and clinical outcomes in Malaysia: A nationwide cohort of the SABINA III study.

Method: In this observational, cross-sectional study, patients (≥12 years) were recruited between July and December 2019 from 15 primary and specialty care centres in Malaysia.

Exhaled Carbon Monoxide Level and Practices among Tobacco and Nicotine Adult Users in Klang Valley, Malaysia.

Tobacco and nicotine derivatives uses are multiple in nature. These include conventional cigarettes (CCs), heated tobacco products (HTPs), and electronic cigarettes (ECs). This study aims to determine the practices, nicotine dependency profile, association with exhaled carbon monoxide (eCO) level, and pulmonary function (PF) among adult product users and non-smokers.

Retrospective review comparing intrapleural fibrinolytic therapy (alteplase) and surgical intervention in complex pleural effusion.

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.

Prevalence and clinical characteristics of malignant lung nodules in tuberculosis endemic area in a single tertiary centre.

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.

Indwelling pleural catheter for malignant pleural effusion with persistent air leak.

Malignant pleural effusion with persistent air leak (PAL) is a rare manifestation of lung malignancy. We present a woman in her 50s with postpleuroscopy PAL. Pleural biopsy confirmed adenocarcinoma with detection of epidermal growth factor receptor mutation in exon 19.

Hydrofluorocarbons pneumonitis as a complication of inhalation injury following air-conditioning repairs.

Hydrofluorocarbon (HFC) pneumonitis is an uncommon cause of inhalation injury. HFCs are a group of chemicals predominantly used for refrigeration and cooling. A 19-year-old air-conditioning technician developed acute onset of dyspnoea and chest tightness while servicing an air conditioner in a confined space.

Modified regimen intrapleural alteplase with pulmozyme in pleural infection management: a tertiary teaching hospital experience.

Background: Current management of poorly draining complex effusions favours less invasive image-guided placement of smaller tubes and adjunctive intrapleural fibrinolysis therapy (IPFT). In MIST-2 trial, intrapleural 10 mg alteplase (t-PA) with 5 mg of pulmozyme (DNase) twice daily for 72 h were used. We aimed to assess the effectiveness and safety of a modified regimen 16 mg t-PA with 5 mg of DNase administered over 24 h in the management of complex pleural infection.

Two cases of cryptogenic organizing pneumonia masquerading as tuberculosis (TB) in a TB endemic area.

Before the era of COVID-19 pandemic, organizing pneumonia (OP) is often underdiagnosed while tuberculosis (TB) is overdiagnosed especially in an endemic area. We report two patients with cryptogenic OP mimicking TB. First, a 56-year-old lady with right upper lobe air space opacity and, second, a 37-year-old lady with left upper lobe cavitary lesion.

Organising pneumonia manifesting as a late-phase complication of COVID-19.

Acute COVID-19 usually lasts 4 weeks from the onset of symptoms. We report two cases of COVID-19-associated organising pneumonia (OP) occurring beyond 4 weeks from the acute onset of symptoms. Both tested positive for SARS reverse transcription-PCR 2 months before presentation with a resolution of respiratory symptoms.

Single dose of rituximab causing organising pneumonia in a patient with B-cell lymphoproliferative disorder.

Rituximab (RTX) is a monoclonal anti-CD20 antibody used to treat non-Hodgkin's lymphoma. RTX-organising pneumonia (RTX-OP) is a rare complication following treatment with RTX. We report a 49-year-old woman, with CD5-negative B-cell lymphoproliferative disorder who developed high-grade fever, dyspnoea and dry cough 3 days after the first dose of RTX.

A partially randomised trial of pretomanid, moxifloxacin and pyrazinamide for pulmonary TB.

Treatment for TB is lengthy and toxic, and new regimens are needed. Participants with pulmonary drug-susceptible TB (DS-TB) were randomised to receive: 200 mg pretomanid (Pa, PMD) daily, 400 mg moxifloxacin (M) and 1500 mg pyrazinamide (Z) for 6 months (6PaMZ) or 4 months (4PaMZ); 100 mg pretomanid daily for 4 months in the same combination (4PaMZ); or standard DS-TB treatment for 6 months. The primary outcome was treatment failure or relapse at 12 months post-randomisation.

Modified Munich chronotype questionnaire for application to short-interval split sleep of non-shift workers.

The Munich Chronotype Questionnaire (MCTQ) has been widely validated among various types of populations. However, determination of chronotype among individuals who have a split sleep pattern with short intervals between the first and second sleep bouts on free days has not yet been reported. This study aimed to validate the MCTQ modified for this purpose by assessing the actual sleep-wake timing against the Morningness-Eveningness Questionnaire (MEQ).
