Cannabinoid hyperemesis syndrome (CHS) is a syndrome of cyclic vomiting associated with chronic cannabis use. As cannabis consumption steadily increases each year, CHS is becoming a commonplace and costly occurrence in hospitals nationwide. Currently, there are no best treatment strategies agreed upon universally. ⋯ CHS is becoming an increasingly prevalent and complicated problem for health care providers and patients. Further research must be done to address the diagnostic and therapeutic challenges of this syndrome.

Comparative Study
Comparison of 3-Factor Versus 4-Factor Prothrombin Complex Concentrate With Regard to Warfarin Reversal, Blood Product Use, and Costs.
Prothrombin complex concentrates (PCCs) are drug products containing varying amounts of vitamin K-dependent coagulation factors II, VII, IX, and X. The evidence comparing 3-factor PCC (3-PCC) versus 4-factor PCC (4-PCC) for warfarin reversal is conflicting. It has been hypothesized that 3-PCC may be less effective than 4-PCC because of relatively lower factor VII content. ⋯ Four-PCC was more effective than 3-PCC with regard to INR reversal in patients taking warfarin, but blood product use was similar. Although 4-PCC is associated with increased reversal costs, it may be cost-effective in terms of INR reversal.

To determine the effects of 80-mg atorvastatin administration for the first time in patients with acute ST segment elevation myocardial infarction (STEMI) before emergency percutaneous coronary intervention (PCI). A total of 118 patients with STEMI who underwent emergency PCI were enrolled in this study. The patients were divided into 80-mg group (n = 59) and 40-mg group (n = 59), according to the loading dose of atorvastatin firstly before operation. ⋯ The incidence of MACE in patients with reflow in 80-mg and 40-mg groups was significantly higher than in patients with no-reflow who were in 80-mg and 40-mg groups for postoperative 12th month (both P < 0.05). The first loading high dose of atorvastatin can significantly prevent occurrence of postoperative no-reflow in patients with STEMI after PCI, reduce HbA1c levels and the incidence of MACE. Clinical randomized controlled trial with larger sample size is required to confirm this finding.

Owing to availability of scanty pharmacokinetic data, dosing decisions in morbid obesity is increasingly challenging in the field of anti-infective drugs. However, in recent years data are emerging that describe the pharmacokinetics of anti-infective drugs in morbidly obese subjects. The objectives of the present work were: (1) to collate the recent reports pertaining to the pharmacokinetics in morbidly obese subjects for several anti-infective drugs and provide an overview of the pharmacokinetic data along with the applicable pharmacodynamics and/or clinical outcome; (2) to perform regression analysis on limited dataset for a few drugs to verify the existence of relationships between Cmax/Ctrough versus steady-state volume of distribution (Vss)/clearance to enable data prediction in morbid obesity subjects; (3) to provide a general discussion on issues and dosing implications. The key findings of this review were: (a) drugs such as vancomycin, ethambutol, and fluconazole, where the VSS is substantially greater in morbidly obese patients, need a dosing strategy with the appropriate body mass descriptors; (b) other drugs such as moxifloxacin, linezolid, doripenem, meropenem, voriconazole, oseltamivir, tigecycline, levofloxacin may not ordinarily need dosing adjustments;
