Pneumonia due to Mycoplasma pneumoniae is common, but it is rarely life-threatening. A case is reported in a previously healthy adult whose illness was severe enough to require treatment with intermittent positive pressure ventilation (IPPV) for 14 days and which resolved after treatment with corticosteroids.

Ondansetron is widely used in general practice for nausea and vomiting due to any cause. We report a rare side effect, life-threatening hypokalaemia following intravenous Ondansetron injection. It may be judicious to restrict the use of Odansetron to patients with severe vomiting due to chemotherapy or in post-operative state. Life-threatening hypokalemia can occur without any warning and may b...

Massive haemoptysis represents a major medical emergency that is associated with a high mortality. Here we present two cases of life-threatening haemoptysis, the first caused by rupture of an aortic aneurysm into the lung in a 37-yr-old woman with polyarteritis nodosa and the second caused by massive bleeding from an angiectatic vascular malformation in the right main bronchus in a 21-yr-old wo...

With both small-cell LTE and Wi-Fi networks available as alternatives for deployment in unlicensed bands (notably 5 GHz), the investigation into their coexistence is a topic of active interest, primarily driven by industry groups. 3GPP has recently standardized LTE Licensed Assisted Access (LTE-LAA) that seeks to make LTE more co-existence friendly with Wi-Fi by incorporating similar sensing an...

Based on the distributed heterogeneous cognitive networks (HCNs) structure from the newest 3GPP release for LTE-A/LTE-B, the resource coordinated allocation scheme is researched to improve the spectrum usage efficiency of the system. Firstly, each network gains the channel conditions by learning scheme; then the information interaction and resource coordination process are carried between neigh...

This is the first clinical practice guideline from the American Academy of Pediatrics that specifically applies to patients who have experienced an apparent life-threatening event (ALTE). This clinical practice guideline has 3 objectives. First, it recommends the replacement of the term ALTE with a new term, brief resolved unexplained event (BRUE). Second, it provides an approach to patient eva...
