ABSTRACT
PURPOSE: Reporting the clinical outcomes, patient satisfaction, and complications following an imaging-guided percutaneous screw fixation in the treatment of sacroiliac joint dysfunction and evaluating the safety and effectiveness of this method. METHODS: We performed a retrospective study on a prospectively gathered cohort of patients with physiotherapy-resistant pain due to sacroiliac joint incompetence that underwent percutaneous screw fixation, between 2016 and 2022 in our center. A minimum of two screws were used in all patients to obtain fixation of the sacroiliac joint, using percutaneous screw insertion under CT guidance, coupled with a C-arm fluoroscopy unit. RESULTS: The mean visual analog scale significantly improved at 6 months of follow-up (p < 0.05). One hundred percent of the patients reported significant improvement in pain scores at the final follow-up. None of our patients experienced intraoperative or postoperative complications. CONCLUSION: The use of percutaneous sacroiliac screws provides a safe and effective technique for the treatment of sacroiliac joint dysfunction in patients with chronic resistant pain.

AIM: It is well known that vitamin D plays an important role in maintaining bone homeostasis and in regulating calcium absorption. The active form of vitamin D interacts with its receptor the VDR that is expressed in multiple tissues and it is involved in platelets (PLTs) function. In the present study we evaluate PLTs' VDR expression in osteoporotic as opposed to healthy subjects. METHODS: We enrolled in the study 77 women with postmenopausal osteoporosis, 33 healthy women of childbearing age, 49 healthy men, and 11 healthy women matched with patients for age and postmenopausal period. Thirty-nine patients had had one femoral fracture occurred after the age of fifty and attributable to primary osteoporosis. Bone mineral density, markers of bone metabolism and VDR levels were measured in all the subjects. RESULTS: Our data show that VDR level is lower in patients as respect to controls and is positively correlated with bone density, but not with markers of bone metabolism. We also found a decrease in the phosphorus levels in patients without differences in vitamin D levels and in the dietary calcium intake. CONCLUSION: The lower VDR expression in osteoporotic could indicate a lower ability to respond to vitamin D, and could be the explanation of the increase in the PTH and decrease in the phosphorus levels in patients with respect to controls.

Children have limited venous access possibilities; therefore, when long-term therapy is necessary, it is better to place a catheter in a central vein. The Port catheter, totally implanted, is less exposed to the risk of infection and permits a normal life. However, there is the possibility of the displacement or fragmentation of the catheter that can be diagnosed initially only by clinical symptoms and later by a chest X-ray. We report a case of disconnection between the Port catheter and the reservoir resulting in catheter migration to the left pulmonary artery.
