Invention refers to neurosurgery, namely methods of marking the skull bones. Method of marking the skull bones includes positioning the patient on the operating table, fixing the head in the required position, marking landmarks for performing trepanation on the skin with a sterile medical dye, incision of the scalp and performing trepanation of the...

Background. Pyrophosphate arthropathy (calcium pyrophosphate dihydrate deposition disease) refers to rare deposition disorders with the onset of the disease after 55 years, manifested by the formation and deposition of calcium pyrophosphate crystals in the joint area, which leads to aseptic inflammation of an immune nature. Clinical manifestations...
