Objectives: Nodal metastasis is one of the most important prognostic factors in early stage cervical carcinoma and has an immense impact on the subsequent management. Thus, searching for nodal metastasis by pelvic lymphadenectomy is an integral part in the surgical management of cervical carcinoma. Complete nodal clearance of lymphatic tissue up to 2 cm above the bifurcation of common iliac vessels is therefore performed as a routine in our unit. The aim of this study is to investigate the incidence and pattern of pelvic lymph node metastases in patients with early stage cervical carcinoma to determine the role of common iliac node dissection in the surgery.
Methods: We retrospectively reviewed 174 operation and histopathology reports of patients who underwent pelvic lymphadenectomy because of stage IA2 to IIA cervical carcinoma. Lymph nodes collected below and above the bifurcation of common iliac vessels were labeled as pelvic nodes and common iliac nodes, respectively. The incidence and distribution of nodal metastases were analyzed.
Results: Complete and selective pelvic lymphadenectomy was performed in 163 and 11 patients, respectively. Nodal metastasis was documented in 35 (20.1%) patients. Pelvic and common iliac nodes were involved in 34 and 8 cases, respectively. All except one patient with common iliac node metastases were also found to have pelvic node metastasis.
Conclusions: In early stage cervical carcinoma, isolated common iliac lymph node metastasis is rare, especially in cases without associated high risk factors. Less extensive pelvic lymphadenectomy may be considered in these patients in order to reduce operation morbidity and time.

A 50-year-old female presented with a 10-day history of progressive swelling and pain in the left lower extremity, ultimately diagnosed with deep vein thrombosis (DVT) and May-Thurner Syndrome (MTS). Initial ultrasound indicated thrombosis involving the left external iliac, femoral, and popliteal veins, among others. Blood tests revealed normocytic anemia, but thrombophilia screening and other blood markers were normal.

Introduction: Osteochondroma is a bony lesion arising from the surface of the bone. It com-prises a large percentage of all benign bone tumors. A unique feature of this tumor is the conti-nuity of cortical and medullary components between the normal bony tissue and aberrant tissue of osteochondroma.

Background: Spinal tuberculosis is a common cause of spinal deformity and neurological dysfunction, with surgical treatment being crucial in severe cases. This study evaluates the efficacy and safety of combined anterior and posterior surgery with autologous tricortical iliac bone and rib grafting for treating spinal tuberculosis.
Methods: We included 61 patients with thoracic tuberculosis, who underwent a surgical procedure involving initial posterior correction, followed by anterior debridement and reconstruction with autologous tricortical iliac bone and rib grafts.
Impact of the Number of Positive Pelvic Lymph Nodes on Risk of Para-Aortic Recurrence in Patients with Clinically Early Cervical Cancer Treated by a Radical Hysterectomy and Pelvic Lymphadenectomy.
Cancers (Basel)

Background: Guidelines recommend the extension of the pelvic radiotherapy volume to the para-aortic region in locally advanced cervical cancer and ≥3 suspicious pelvic lymph nodes (PLN) on imaging. Whether this recommendation is also valid for clinically early stages is uncertain. The objective of this study was to investigate the para-aortic (PAO) lymph node recurrence rate in patients with early-stage cervical cancer, ≥3 metastatic PLN, and negative common iliac nodes after a radical hysterectomy followed by pelvic (chemo)radiotherapy without extension to the PAO region.
