The effect of cholecystectomy on 25-hydroxyvitamin D levels and bone mineral density in postmenopausal women.

Unlabelled: Vitamin D deficiency has been reported in patients with gastrointestinal disorders. Little is known on the potentially deleterious effect of cholecystectomy on vitamin D levels and osteoporosis. We found that 25-hydroxyvitamin D levels and bone mineral density were lower in patients with prior cholecystectomy.

Giant cell tumor of the metacarpal bone in children: free osteoarticular metatarsal transfer: case report.

We present a successful total resection of metacarpal bone and nonvascularized joint transfer in a giant cell tumor of the fourth metacarpal bone in a 13-year-old girl. At the 6-year follow-up, a good functional outcome was achieved, with 85° range of motion of the metacarpophalangeal joint and no clinical or radiographic evidence of tumor recurrence and no signs of degeneration of the joint.

Clinical significance of lymph node ratio in locally advanced breast cancer molecular subtypes.

Background: The ratio of metastatic to dissected lymph nodes (lymph node ratio; LNR) is a sensitive and superior prognostic factor for lymph node evaluation, but its relationship to cancer subtypes is unclear.

Patients And Methods: Data from 469 patients with axillary lymph node metastasis out of 640 early breast cancer cases were retrospectively analyzed. They were classified into 4 molecular subtypes; luminal A, luminal B HER2(+), HER2 overexpression, basal-like.

Lymph node ratio assessment of brain metastasis in early breast cancer cases.

Background: Ten to 30% of early breast cancer (EBC) patients develop brain metastasis (BM) during their follow-up. In this study, we aimed to evaluate importance of the lymph node ratio (LNR) in development of BM in EBC cases.

Materials And Methods: Ninety patients whom had axillary metastases in lymph nodes at their initial diagnosis and developed BM during 5-year follow-up were detected in 950 EBC patients.
