ABSTRACT
INTRODUCTION: Although the intervention of knee arthroplasty became routine, there is no standard reference on the densitometric characteristics of the patella before and after surgery. Scope of this work is the evaluation of patellar bone density before and after unilateral knee arthroplasty. PATIENTS AND METHODS: BMD was assessed by DEXA examination in 146 individuals, who have been divided into three distinct groups. Group I: 68 subjects with a mean age of 70.6 years, with an unilateral femoral-tibial knee prothesis. Group II: healthy subjects of similar age (average: 64) and without implants. Group III: healthy adults with a mean age of 26.6 years. The follow-up was performed at 6 months to a maximum of 2 years post surgery. RESULTS: The results were obtained from 68 subjects examined with the DEXA software dedicated to the forearm, which turned out to be the most appropriate for our purpose. The follow-up performed every 6 months after surgery showed a reduction of the density values in the operated knee in the 1st control with a return to the pre-surgiucal situation in the control performed after 1 year. In subsequent checks there was a further increase of the patellar density of the operated knee. CONCLUSION: Patellar DEXA examination is recommended as an addition to the clinical and radiological standard examination.

This study is aimed at identifying the collateral circulation in case of femoral-aorta-iliac axis obstruction, with the purpose of a more correct therapeutic indication being either medical or surgical or physiotherapeutic or combined.

Pancreas divisum is a genetic defect associated with recurrent acute pancreatitis due to insufficient drainage of the accessory pancreatic duct. Seven young patients diagnosed with pancreatic divisum and thickening of the gallbladder bile as shown on magnetic resonance cholangio-pancreatography without pancreatic ductal changes underwent laparoscopic cholecystectomy. During the mean follow-up of 32 months no episode of pancreatitis was reported. There is an association between PD and higher concentration of bile in the gallbladder. Cholecystectomy can be considered curative in patients with PD in the absence of indications for major surgery.

This case report is about a 70-years-old female patient, suffering from discal hernia, with compression of the iliac vein, that led to the formation of deep vein thrombosis of the lower limbs. The angio-CT scan revealed the starting point of the L4- L5 compression where a voluminous discal hernia caused deep vein thrombosis, with the involvement the femoro-popliteal venous axis. Blood samples and PET-CT scans excluded other possible etiologic factors. This case demonstrates how a voluminous discal hernia can cause venous thrombosis.
