Knowledge and Attitude of Physicians Toward Prescribing Antibiotics and the Risk of Resistance in Two Reference Hospitals.

Introduction: Antibiotics are essential and abundantly prescribed in hospitals because of their effectiveness and lifesaving benefits. However, the unnecessary use of antibiotics has been observed in earlier studies, and it has persisted through recent years as a major issue since it is one of the leading causes of antibiotic resistance. The increase in antibiotic resistance nowadays is one of the most critical concerns in global public health around the world.

Successful treatment of multi-focal XDR tuberculous osteomyelitis.

We herein describe the nosocomial transmission of a pre-XDR or MDR case of pulmonary tuberculosis in a HIV-negative health care worker in an area endemic for MDR and XDR tuberculosis.
