Case Reports
Acute exacerbation of idiopathic pulmonary fibrosis as the initial presentation of the disease.
The clinical course of patients with idiopathic pulmonary fibrosis (IPF) is generally marked by a decline in pulmonary function over time, although recently there is increasing recognition that fatal deterioration from acute exacerbation can occur at any stage. The patient described in the present case study was a 65-yr-old male who presented with exertional dyspnoea and fever of 2 weeks' duration. He had no history of chronic lung disease or physiological or radiological hallmarks of pre-existing disease. ⋯ Unusual findings on high-resolution computed tomography scan were also noted. We presume that in this case acute exacerbation developed in the very early course of IPF. Given the possibility that similar cases may have arisen among patients diagnosed with acute interstitial pneumonia or acute respiratory distress syndrome, the histopathology of rapidly progressive interstitial pneumonia may need to be revisited.

Review Case Reports
Pulmonary necrobiotic nodules: a rare extraintestinal manifestation of Crohn's disease.
The present article reports the case of a 22-yr-old female with new onset Crohn's colitis, anterior uveitis and multiple pulmonary nodules which, on histological examination, were necrobiotic nodules. This is a rare but recognised pulmonary extraintestinal manifestation of Crohn's disease and only the fourth reported case. The present case report is followed by a brief review of the relevant literature.

The prognosis for patients with pulmonary hypertension remains poor despite recent treatment advances, and there is a need for therapies with new modes of action. Nitric oxide (NO) is an endogenous vasodilator, the levels of which are regulated throughout the lung to ensure preferential perfusion of well-ventilated regions. Drugs that act in synergy with endogenous NO would therefore promote pulmonary vasodilation while maintaining optimal gas exchange. ⋯ It also caused systemic vasodilation, which was well tolerated but should be monitored in future studies. Dose titration of riociguat should promote pulmonary vasodilation while maintaining control of systemic effects, and has been investigated in a phase-II study of patients with pulmonary arterial hypertension or chronic thromboembolic pulmonary hypertension. Preliminary results indicate that phase-III trials are warranted.

Recent advances in the field of pulmonary hypertension (PH) have provided clinicians with a range of treatment options, but effective disease management in children presents a unique challenge. The present article will discuss the steps being taken to address unmet needs in paediatric PH. Understanding the epidemiology of paediatric PH is essential to guide management decisions, but such epidemiological data are scarce. ⋯ In summary, further epidemiological and treatment data are needed for paediatric pulmonary hypertension. The international TOPP registry will provide a valuable insight, but this must be complemented by research and development of adapted paediatric therapies. Dedicated childhood pulmonary hypertension services would optimise the diagnosis and management of this life-threatening disease.
