Allopurinol is an FDA-Approved xanthine oxidase inhibitor that uses in the treatment of gout, hyperuricemia and uremic kidney stones in the patients with an increased level of uric acid excretion. Xanthine oxidase acts by converting hypoxanthine and xanthine to uric acid, and therefore its inhibition will result in decreased production of uric acid. The most common side effects of this medication are as follows: maculopapular rashes, hives, itching, headache, dizziness, abnormal hair loss, fever and hypersensitivity reaction...

Acinetobacter species are widely distributed in soil, water and hospital environment. In addition to A. calcoaceticus-baumannii complex, the clinically most relevant species, there are other genomospecies which are less frequently identified, mostly due to lack of accurate methods for routine identification. We describe the first case of post-traumatic endophthalmitis caused by otherwise non-pathogenic A. radioresistens, in India. Gram-negative coccobacilli were observed on Gram stain and culture of vitreous fluid specimen, and identified biochemically as Acinetobacter spp...

Tuberculosis (TB) is a public health problem in developing countries. In recent decades, the incidence of the disease has been gradually reducing in Iran. However, the reducing incidence of the disease has stopped in the country during recent years. It could be due to increase of immigration, diabetes, HIV/AIDS, and the prevalence of drug-resistant strains. In order to prevent the spread of TB cases and control this disease, it is essential to identify the predisposing factors, which may be related to bacteria, host and environment...
