Article Synopsis
  • The German Federal Institute for Medicines and Medical Products has restricted fosfomycin use in transrectal biopsy of the prostate (TRBP), highlighting the urgent need for alternative antibiotic prophylaxis options.
  • A study involving 359 patients at the University of Regensburg found that using amoxicillin/clavulanic acid resulted in a low post-TRBP infection hospitalization rate of only 2.8%, suggesting its effectiveness as an alternative.
  • Amoxicillin/clavulanic acid is classified as an "Access" antibiotic by the WHO, making it a preferable choice; however, the study's limitations include not conducting rectal swabs and urine cultures for every patient.

Osteoporosis, a systemic skeletal disorder, is expected to affect 60% of women over 50. While dual-energy X-ray absorptiometry (DXA) scans are the current gold standard for diagnosis, they are typically used only after fractures occur, highlighting the need for early detection tools. Initial studies have shown panoramic radiographs (PRs) to be a potential medium, but these have methodological flaws.

Since 1924, it has been possible to qualify as a specialist in urology in Germany. The first hospital departments for the treatment of urological conditions were established as early as the end of the German Empire and the Weimar Republic. However, the beginning of specialist medical care in the Bavarian administrative district of Upper Palatinate, often known as the "poorhouse" of Germany until the second half of the last century, was much later.
