Spanish Society of Medical Radiology Journal Club: History, analysis and perspectives after ten years of experience.

We define a journal club as a group of people who meet to critically read and discuss scientific articles. In medicine, journal clubs are a very important part of training during residency programs. In 2013, the Spanish Society of Medical Radiology's (SERAM) journal club was established with the aim of promoting the acquisition of non-interpretative skills and training in scientific journalism during residency. After nearly 10 years, more than 137 reviewers at 54 hospitals have formed part of the SERAM's journal club. In this time period, the number of reviewers, publications, and visits to our website have increased progressively. The SERAM's journal club currently employs a structured workflow that is organized into quarterly groups and supported by a peer-review system. In the future, the SERAM's journal club aims to internationalize its content beyond the Spanish-speaking community, increase its presence in social networks, and incorporate audiovisual content.

Atypical bacterial infections of the central nervous system transmitted by ticks: An unknown threat.

Infections of the central nervous system caused by atypical bacteria are becoming more common. Borrelia burgdorferi and Rickettsia conorii are microorganisms transmitted by ticks; infection with these bacteria result in a wide spectrum of manifestations on imaging. In areas where these tick-borne microorganisms are endemic, including Spain, these infections must be included in the differential diagnosis of patients with a variety of systemic and neurologic symptoms. The clinical presentation of these infections is nonspecific, and CT is normally the initial imaging technique, although MRI is more sensitive to early changes. On MRI, these infections can manifest as small lesions in the deep supratentorial white matter that are hyperintense on T2-weighted/FLAIR sequences. It is fundamental to know the imaging characteristics of the different atypical bacterial infections and their differential diagnoses. Good history taking combined with complementary tests (blood tests and CSF analysis) and the neuroimaging findings can help reach the right diagnosis and enable appropriate treatment, thereby preventing possible neurological sequelae.
