Community acquired pneumonia (CAP) may present as life-threatening infection with uncertain progression and outcome of treatment. Primary aim of the trial was determination of the cut-off value of serum interleukin-6 (IL-6) and procalcitonin (PCT) above which, 30-day mortality in hospitalized patients with CAP, could be predicted with high sensitivity and specificity. We investigated correlation between serum levels of IL-6 and PCT at admission and available scoring systems of CAP (pneumonia severity index-PSI, modified early warning score-MEWS and (Confusion, Urea nitrogen, respiratory rate, Blood pressure, ≥65 years of age-CURB65). ⋯ Both IL-6 and PCI are significant for prediction of 30-day mortality in hospitalized patients with CAP. Serum levels of IL6 correlate with major CAP scoring systems.

This paper summarizes the roundtable discussion in September 25, 2013, Riyadh, Saudi Arabia as part of the World Sepsis Day held in King Abdulaziz Medical City, Riyadh. The objectives of the roundtable discussion were to (1) review the chasm between the current management of sepsis and best practice, (2) discuss system redesign and role of the microsystem in sepsis management, (3) emphasize the multidisciplinary nature of the care of sepsis and that improvement of the care of sepsis is the responsibility of all, (4) discuss the bundle concept in sepsis management, and (5) reflect on the individual responsibility of the health care team toward sepsis with a focus on accountability and the moral agent.

Idiopathic pulmonary fibrosis (IPF) is rare and can be challenging to diagnose. Limited data is available from the Middle Eastern region, especially Saudi Arabia. ⋯ In Saudi Arabia, IPF patients tended to be slightly older and the disease progression was somewhat slower than reported IPF cohorts in other populations. They had frequent hospital admissions and a long hospital length of stay. The influence of genetics and co-morbid diseases on the incidence and outcome of IPF should be explored further.

Pulmonary hypertension (PH) is a phenotype characterized by functional and structural changes in the pulmonary vasculature, leading to increased vascular resistance.[12] The World Health Organization has classified PH into five different types: arterial, venous, hypoxic, thromboembolic or miscellaneous; details are available in the main guidelines. Group I of this classification, designated as pulmonary arterial hypertension (PAH), will remain the main focus here. The pathophysiology involves signaling, endothelial dysfunction, activation of fibroblasts and smooth muscle cells, interaction between cells within the vascular wall, and the circulating cells; as a consequence plexiform lesions are formed, which is common to both idiopathic and heritable PAH but are also seen in other forms of PAH.[234] As the pathology of PAH in the lung is well known, this article focuses on the genetic aspects associated with the disease and is a gist of several available articles in literature.
