[Effect of ultrasound-guided brachial plexus block on perioperative pain management of total elbow arthroplasty].

Background: Ultrasound-guided brachial plexus block (UGBB) makes it possible to block both lateral and medial aspects of the skin overlying the elbow, which are mainly innervated by C5 and T1 roots of brachial plexus, respectively. The effect of UGBB on perioperative pain relief in total elbow arthroplasty (TEA) was evaluated.

Methods: Twenty-one patients scheduled to undergo TEA with general anesthesia from January 2009 to December 2010 were assigned to a group receiving UGBB (Block group, n = 10) and a group receiving general anesthesia alone (General group, n = 11).

Emphysematous liver abscesses complicated by septic pulmonary emboli in patients with diabetes: two cases.

An emphysematous liver abscess is a fatal condition that often occurs in patients with uncontrolled diabetes mellitus. I herein describe two cases of Klebsiella pneumoniae-induced emphysematous liver abscesses complicated by septic pulmonary emboli in patients with poorly controlled diabetes mellitus.

A 46-year-old woman was transferred to our emergency unit because of impaired consciousness and respiratory failure with the history of excessive pesticide intake. The patient was hypersalivative and had bilateral pupillary miosis. Laboratory results showed markedly decreased cholinesterase.

Co-infection with invasive pulmonary aspergillosis and Pneumocystis jirovecii pneumonia after corticosteroid therapy.

A 95-year-old man with chronic obstructive pulmonary disease and chronic hepatitis C virus infection was treated for acute lung injury caused by Chlamydophila pneumoniae with antibiotics and high-dose corticosteroids. In total, 7,500 mg methylprednisolone and 680 mg prednisolone were administered over 21 days. However, respiratory failure progressed, and chest computed tomography (CT) scan showed bilateral ground-glass opacity and cavity-forming consolidation in the right upper lobe.
