Acute generalized exanthematous pustulosis: a rare clinical entity with use of piperacillin/tazobactam.
Acute generalized exanthematous pustulosis (AGEP) is a rare disorder characterized by an acute episode and sudden onset of erythematous and edematous eruptions of hundreds of sterile pustules. It is a self-limiting condition accompanied by fever and has a rapid course. ⋯ We report a case of a patient who developed this rare skin condition with the use of piperacillin/tazobactam (Zosyn). This is only second case of AGEP reported in literature with the use of Zosyn.

It is well known that electric shock can both initiate and terminate ventricular fibrillation. Refractory ventricular fibrillation (RVF) may often be an iatrogenic paradoxical result of early, frequent, excessive salvos of DC current countershocks and inappropriate off-label drug use, particularly aggressive epinephrine administration. Evidence suggests that the current advanced cardiac life support pharmacology protocol for cardiac resuscitation may contribute to disappointing survival in patients with out-of-hospital cardiac arrest. ⋯ Catechalomines cause coronary spasm and puts myocardial metabolism into damaging hypermetabolic overdrive to support the "fight or flight reflex" rapidly depleting adenosine triphosphate needed for cardiac electrical and mechanical recovery. Moreover, the value of epinephrine to resuscitation has never been demonstrated in a controlled human study, whereas its potential damage has been largely ignored. Epinephrine's potential deleterious actions that might compromise resuscitation are well established and reviewed here.

The timely administration of appropriate antifungal therapy for Candida bloodstream infections (CBSI) improves clinical outcomes. However, little data exist on the effect of antifungal therapy in patients with septic shock and candidemia. We describe antifungal treatment of patients with septic shock due to CBSI and its impact on in-hospital mortality. ⋯ Appropriate antifungal therapy was administered to 24 patients; 15 (63%) of these patients died. Classification and regression tree analysis revealed that patients who received appropriate antifungal therapy within 15 hours of collecting the first positive Candida blood culture had improved survival (P = 0.03). Early, appropriate antifungal therapy improves survival among patients with septic shock due to CBSI.

The antioxidant activity of L-carnosine (beta-alanyl-L-histidine, bioactivated in ocular tissues) versus N-acetylcarnosine (N-acetyl-beta-alanyl-L-histidine, ocular-targeted small dipeptide molecules) was studied in aqueous solution and in a lipid environment, employing liposomes as a model of lipid membranes. Reactive oxygen species (ROS) were generated by an iron/ascorbate promoter system for induction of lipid peroxidation (LPO). L-carnosine, which is stabilized from enzymatic hydrolysis, operates as a universal aldehyde and ROS scavenger in both aqueous and lipid environments and is effective at preventing ROS-induced damage to biomolecules. ⋯ Overall, accumulated study data demonstrate that the IVP-designed new vision-saving drugs, including N-acetylcarnosine eyedrops, promote health vision and prevent vision disability from senile cataracts, primary open-angle glaucoma, age-related macular degeneration, diabetic retinopathy, and aging. N-acetylcarnosine eyedrop therapy is the crown jewel of the anti-aging medical movement and revolutionizes early detection, treatment, and rejuvenation of aging-related eye-disabling disorders. N-acetylcarnosine, as an innovative medical science tool and component of the home medicine and alternative medicine approaches, has the potential to alleviate visual impairment and its associated social, economic, and political woes for an aging population.
