Methods: 136 postmenopausal women with urogenital aging symptoms were enrolled in this prospective randomized study.

Patients: randomly divided into two groups and each group consisted of 68 women.

Painful pelvic recurrence of rectal cancer: percutaneous radiofrequency ablation treatment.

Purpose: To retrospectively evaluate the feasibility and efficacy of computed tomography (CT)-guided radiofrequency thermal ablation (RFA) in reducing the pain in patients with painful pelvic recurrence of rectal cancer ineligible for surgical resection.

Material And Methods: Twelve consecutive patients (10 men and 2 women; mean age 67 ± 10 years) with painful pelvic recurrence of rectal cancer underwent CT-guided RFA treatments under conscious sedation. At baseline, in all patients pelvic-sacral pain was classified as severe by Visual Analog Scale (VAS; VAS score ≥75 mm).

Cesarean section and right femur fracture: a rare but possible complication for breech presentation.

Background. The breech extraction of the fetus through the vagina has a greater risk of hip fracture compared with the extraction by abdominal route. Case.

Ultrasound anatomy of normal nails unit with 18 mhz linear transducer.

Interest is growing in non-invasive diagnostic methods for nails in dermatological pathology. Currently, nail disease diagnosis is based mostly on clinical evaluation; instrumental examination, traditionally, has been performed by magnetic resonance. Ultrasound (US) can be proposed as an easier and more available method for the study of the nail apparatus.

Omental Well-Differentiated Liposarcoma: US, CT and MR Findings.

Liposarcomas are the most common of sarcoma tumours, they are usually located in the lower limbs, retroperitoneum, or abdominal cavity; up to date, only a few cases of omental liposarcoma with different histotype have been described. We present a case of omental well-differentiated liposarcoma and discuss imaging findings on ultrasound, computed tomography, and magnetic resonance to differentiate omental liposarcomas from other abdominal tumour entities.

The role of planar scintimammography with high-resolution dedicated breast camera in the diagnosis of primary breast cancer.

Planar scintimammography (SM) acquired with a conventional gamma camera has proved a useful complementary tool to mammography (Mx) in breast cancer (BC) diagnosis, but with unsatisfactory sensitivity in small size carcinomas. In this study we assessed the role of planar SM with a high-resolution dedicated breast camera (DBC) in BC diagnosis, comparing the results with those of Mx.A consecutive series of 145 patients scheduled for biopsy for suspected BC underwent Tc-99m tetrofosmin planar SM using a newly developed DBC.

Emergency surgical conditions after biliopancreatic diversion.

Background: Urgent late complications of biliopancreatic diversion (BPD) are rare and often require the experience of a bariatric surgery team for their immediate resolution.

Postoperative radiologic evaluation of the esophagus.

A wide range of surgical procedures are performed for either benign and malignant esophageal lesions, that may be classified as demolitive or conservative interventions. The former is characterized by resection and replacement of the esophagus with another organ, whereas conservative surgery is obtained preserving esophageal function without resection. Knowledge of surgical techniques and major complications is extremely important for a correctly performed radiographic study and a proper interpretation of the imaging findings.
