Background: Aerobic vaginitis (AV) is a state of abnormal vaginal microbiota, which is associated with increased numbers of aerobic, enteric bacteria and inflammation of the vaginal epithelium. Anti-microbial treatment combined with anti-inflammatory therapy could be useful in the treatment of this condition. It is known that calcitriol, the active form of vitamin D, plays an important role in modulating the immune response in several inflammatory diseases.

Many patients with underlying medical conditions are treated with local anesthetics in dental clinics. Dental local anesthetic cartridges contain the vasoconstrictor adrenaline, which can affect the cardiovascular system. For this reason, the adrenaline in the cartridge (2% lidocaine + 1:80,000 adrenaline) is sometimes diluted in order to avoid hemodynamic changes in these patients.

Recently, cold and cough dosage forms have gained significant attention due to their use in the supportive protocols for managing COVID-19 symptoms. In this study, a pharmaceutical formulation containing Paracetamol (PAR), Guaifenesin (GUA), and Phenylephrine hydrochloride (PHE) was investigated for spectral resolution and quantification using advanced spectrophotometric methods. The spectra of these components were significantly overlapped and present in their combined tablet in a challenging ratio of 250:100:5 for PAR, GUA, and PHE, respectively.

To report the preliminary result of empiric embolization for angiographycally-negative lower gastrointestinal bleeding (LGIB) by using the pharmaco-induced vasospasm technique with or without the adjunctive use of intra-arterial multi-detector computed tomography (MDCT). 23 LGIB patients with positive MDCT findings but negative angiographic results underwent empiric pharmaco-induced vasospasm therapy. The presumed bleeding artery was semi-selectively catheterized, and a segment of bowel was temporarily spasmed with bolus injection of epinephrine and immediately followed by 4-h' vasopressin infusion.
