Disorders of the visual system are one of the main features of multiple sclerosis (MS), and have a great impact on the quality of life of patients. Although optic neuritis is the most frequent manifestation, there are other ophthalmological processes not related to neuritis, a knowledge of which is very useful in the management of patients with MS. These abnormalities are described, grouped into impairments of the afferent pathway, efferent pathway, or upper cerebral areas. Additionally, the main ophthalmological side effects of the drugs currently used in the control of MS are described.

Clostridioides difficile is the main cause of healthcare-associated diarrhoea in adults. The incidence of C.difficile infection (CDI) has increased in recent years. The risk of recurrence of CDI is 15%-25% in a first episode and this risk is increased in subsequent episodes. ⋯ These are laborious and slow techniques and therefore they have been replaced in clinical practice by the application of a multi-step algorithm that includes the detection of glutamate dehydrogenase (GDH), toxins and molecular techniques. The treatment of choice for CDI is Vancomycin. In recent years, new drugs and new treatment strategies have appeared that are especially useful in the treatment of relapses of CDI.
