Current cervical total disc replacement (TDR) designs incorporate a variety of different biomaterials including polyethylene, stainless steel, titanium (Ti), and cobalt-chrome (CoCr). These materials are most important in their utilization as bearing surfaces which allow for articular motion at the disc space. Long-term biological effects of implanted materials include wear debris, host inflammatory immune reactions, and osteolysis resulting in implant failure. We review here the most common materials used in cervical TDR prosthetic devices, examine their bearing surfaces, describe the construction of the seven current cervical TDR devices that are approved for use in the United States, and discuss known adverse biological effects associated with long-term implantation of these materials. It is important to appreciate and understand the variety of biomaterials available in the design and construction of these prosthetics and the considerations which guide their implementation.

Background: We aimed to document childhood onset mevalonate kinase deficiency (MKD) and to explore treatment responses and diagnostic challenges in regions endemic to familial Mediterranean fever (FMF).
Methods: This retrospective study included patients under 18 years of age, diagnosed with MKD and followed for at least six months at the pediatric rheumatology department of Istanbul University - Cerrahpaşa Medical Faculty between 2016 and 2024.
Results: Of 33 patients, 51.

Purpose: Low back and neck pain are increasing worldwide, even in children. However, Italy lacks validated tools for the assessment of children and adolescents with spine disorders. The Young Spine Questionnaire (YSQ) seems to be an appropriate option.

Objective: Endometrial cancer (EC) and epithelial ovarian cancer (EOC) affect women of all ages, and the incidence of endometrial cancer in premenopausal women is rising. Menopause can be detrimental to longevity and quality of life, but evidence suggests estrogen therapy (ET) is safe in these patients. The purpose of this study was to evaluate the practice patterns of gynecologists and gynecologic oncologists (GYO) in the United States in regards to prescription of ET to gynecologic cancer patients.

Background: Metabolic syndrome (MetS) and sarcopenia are major global public health problems, and their coexistence significantly increases the risk of death. In recent years, this trend has become increasingly prominent in younger populations, posing a major public health challenge. Numerous studies have regarded reduced muscle mass as a reliable indicator for identifying pre-sarcopenia.

Purpose: To investigate the role of personal risk factors in the occurrence of the vascular, neurological and fibroproliferative disorders of the hand-arm vibration syndrome (HAVS) in workers groups exposed to hand-transmitted vibration (HTV).
Methods: HAVS prevalence and incidence data were pooled across a series of cross-sectional studies (total sample: 1272 HTV workers, 579 controls) and prospective cohort studies (total sample: 377 HTV workers, 138 controls) conducted in Central and North-Eastern Italy. The pooled studies included detailed individual-level information about HTV exposure, personal risk factors, medical comorbidities and HAVS disorders.
