Clinical guidelines on pneumonia management and treatment
This post features two clinical guidelines on the management of community acquired pneumonia. The British Thoracic Society updated this year many recommendations, including when to order a chest X-ray, and antibiotic management.

Vancomycin mechanism of action: an animation
Vancomycin is a tricyclic glycopeptide that has gained clinical importance thanks to its effectiveness against organisms such as MRSA and enterococci. It has activity against Gram-positive rods and cocci, Gram-negative rods are resistant to its bactericidal action. Some clinical uses of IV vancomycin include treatment of infective endocarditis and sepsis caused by MRSA. Since vancomycin

SMC recommendations for doripenem : second or third line treatment of intra-abdominal infections
The Scottish Medicines Consortium issued an advice on the current indications for doripenem (Doribax): Doripenem (Doribax) is accepted for restricted use within NHS Scotland for the treatment of complicated intra-abdominal infections in adults. In patients with complicated intra-abdominal infection, doripenem is associated with clinical cure rates non-inferior to those of another carbapenem. Doripenem should be

Protein synthesis inhibitors: aminoglycosides mechanism of action animation. Classification of agents
The following animation depicts the mechanism of action of aminoglycosides. This antibiotic class includes drugs such as gentamicin, streptomycin (used for TB treatment), amikacin, among others. Aminoglycosides mechanism Susceptible gram-negative organisms allow aminoglycosides to diffuse through porin channels in their outer membranes. These organisms also have an oxygen-dependent system that transports the drug across the
