Pulmonary veno-occlusive disease: A systematic review of risk factors, clinical presentation, diagnostic investigations, treatment outcomes and prognostic factors.

Pulmonary veno-occlusive disease (PVOD) is a rare cause of pulmonary hypertension. We aimed to systematically evaluate published cases of PVOD to provide an overview of their clinical presentation, management and prognosis to assist early identification and treatment. We conducted a literature search of PubMed and Embase databases for adult cases of 'pulmonary veno-occlusive disease' and 'pulmonary capillary haemangiomatosis'.

Delayed diagnosis of Swyer-James-MacLeod syndrome.

Swyer-James-MacLeod Syndrome is a rare obliterative lung disease typically caused by childhood infection resulting in arrested pulmonary development. Imaging findings include unilateral hyperlucency on chest x-ray, and hyperlucency, hypovascularity and expiratory gas trapping on computed tomography. Recognition of abnormal imaging can lead to earlier diagnosis and institution of appropriate management.

PIVET-ED: A Prospective, Randomised, Single-Blinded, Sham Controlled Study of Pelvic Vein Embolisation for Treatment of Erectile Dysfunction.

Purpose: Erectile Dysfunction (ED) is defined as the inability to obtain or maintain an erection firm enough for satisfactory sexual performance and affects the quality of life of over 50% of men aged over 40 years. Venogenic ED is elucidated as a cause in a subgroup of patients. The study aims to investigate the clinical success, technical success, safety and durability of venous embolisation for management of venogenic ED.

Diagnosis and management of idiopathic pulmonary fibrosis: Thoracic Society of Australia and New Zealand and Lung Foundation Australia position statements summary.

Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial lung disease associated with debilitating symptoms of dyspnoea and cough, resulting in respiratory failure, impaired quality of life and ultimately death. Diagnosing IPF can be challenging, as it often shares many features with other interstitial lung diseases. In this article, we summarise recent joint position statements on the diagnosis and management of IPF from the Thoracic Society of Australia and New Zealand and Lung Foundation Australia, specifically tailored for physicians across Australia and New Zealand.

The interstitial lung disease multidisciplinary meeting: A position statement from the Thoracic Society of Australia and New Zealand and the Lung Foundation Australia.

Interstitial lung diseases (ILD) are a diverse group of pulmonary diseases for which accurate diagnosis is critical for optimal treatment outcomes. Diagnosis of ILD can be challenging and a multidisciplinary approach is recommended in international guidelines. The purpose of this position paper is to review the evidence for the use of the multidisciplinary meeting (MDM) in ILD and suggest an approach to its governance and constitution, in an attempt to provide a standard methodology that could be applied across Australia and New Zealand.

Health-related quality of life in idiopathic pulmonary fibrosis: Data from the Australian IPF Registry.

Background And Objective: Studies analysing the effect of worsening pulmonary physiological impairment in idiopathic pulmonary fibrosis (IPF) with respect to quality of life have been limited to single centres or highly selected trial populations. The aim of this study was to determine the principal determinants of baseline and longitudinal health-related quality of life (HRQoL) in a large unselected IPF population.

Methods: We used the Australian IPF Registry to examine the relationship between HRQoL, measured using the St George Respiratory Questionnaire (SGRQ), and demographic features, physiological features, co-morbidities and symptoms.

Clinical impact of the interstitial lung disease multidisciplinary service.

Background And Objective: Multidisciplinary discussions (MDDs) have been shown to improve diagnostic accuracy in interstitial lung disease (ILD) diagnosis. However, their clinical impact on patient care has never been clearly demonstrated. We describe the effect that an ILD multidisciplinary service has upon the diagnosis and management of patients with suspected ILD.

Proximal and distal gastro-oesophageal reflux in chronic obstructive pulmonary disease and bronchiectasis.

Background And Objective: The aims of this observational study were (i) to examine the prevalence of symptomatic and clinically silent proximal and distal gastro-oesophageal reflux (GOR) in adults with chronic obstructive pulmonary disease (COPD) or bronchiectasis, (ii) the presence of gastric aspiration, and (iii) to explore the possible clinical significance of this comorbidity in these conditions.

Methods: Twenty-seven participants with COPD, 27 with bronchiectasis and 17 control subjects completed reflux symptom evaluation and dual-channel 24 h oesophageal pH monitoring. In those with lung disease, pepsin levels in sputum samples were measured using enzyme-linked immunosorbent assay, with disease severity (lung function and high-resolution computed tomography) also measured.

Investigation of the safety of irreversible electroporation in humans.

Purpose: A single-center prospective nonrandomized cohort study was performed to investigate the safety of irreversible electroporation (IRE) for tumor ablation in humans.

Materials And Methods: Thirty-eight volunteers with advanced malignancy of the liver, kidney, or lung (69 separate tumors) unresponsive to alternative treatment were subjected to IRE under general anesthesia. Clinical examination, biochemistry, and computed tomography (CT) scans of the treated organ were performed before, immediately after, and at 1 month and 3 months after the procedure.

Should lung transplant recipients routinely perform airway clearance techniques? A randomized trial.

Background And Objective: Despite the widespread use of airway clearance (AC) techniques to clear excessive secretions and improve lung function, little is known about their efficacy following lung transplantation (LTx). This study compared the effects of two AC strategies (proactive vs reactive) on a range of clinical outcomes following LTx.

Methods: A prospective randomized trial was conducted.

'Benign' hepatic portal venous gas.

The presence of portal venous gas within the hepatic parenchyma is usually associated with a guarded prognosis and a mortality rate approaching 75%. However, there are infrequent causes of portal venous gas not associated with dire clinical outcomes. We describe three patients who made uneventful clinical recoveries after presenting with clinical and imaging manifestations of ischaemic bowel and hepatic portal venous gas, two of which had distended but non-necrotic bowel at laparotomy.
