Validation of the mIBG skeletal SIOPEN scoring method in two independent high-risk neuroblastoma populations: the SIOPEN/HR-NBL1 and COG-A3973 trials.

Background: Validation of the prognostic value of the SIOPEN mIBG skeletal scoring system in two independent stage 4, mIBG avid, high-risk neuroblastoma populations.

Results: The semi-quantitative SIOPEN score evaluates skeletal meta-iodobenzylguanidine (mIBG) uptake on a 0-6 scale in 12 anatomical regions. Evaluable mIBG scans from 216 COG-A3973 and 341 SIOPEN/HR-NBL1 trial patients were reviewed pre- and post-induction chemotherapy.

Radiosynoviorthesis in hemophilic joints with yttrium-90 citrate and rhenium-186 sulfide and long term results.

Repeated bleeding in the joint cavities is the most annoying symptom and often has disabling effects in patients with hemophilia (PWH). Our aim was to study the effect of radiosynovectomy (RSO) with beta particle-emitting radiocolloids in the treatment of hemorhagic arthropathy. We have treated 22 joints from 18 patients with hemophilia A, from April 2008 to February 2012, 5 knees, 11 elbows and 6 ankles.

Computed tomography angiography-guided recanalization of saphenous vein graft chronic total occlusion.

Computed tomography (CT) angiography can augment conventional coronary angiography relative to length of vessel occlusion and quality of distal run-off. In this case report we describe the significance of CT angiography in the revascularization decision-making process of a patient following occlusion of both coronary artery bypass grafts.

Cardiac structural and functional changes in competitive amateur cyclists.

Purpose: To assess cardiac structural and functional changes induced by competitive amateur cycling.

Methods: Fifty-one young competitive amateur male cyclists and 47 age- and gender-matched control subjects underwent complex transthoracic echocardiographic examination focused on the detailed assessment of cardiac size and function, especially of the left ventricle (LV). Subsequently, spiroergometry was performed in all study participants and its results were compared to echocardiographic data.

Lymphatic mapping in endometrial cancer: comparison of hysteroscopic and subserosal injection and the distribution of sentinel lymph nodes.

Introduction: Endometrial cancer incidence increases over the age of 65 and lymphadenectomy in these women is a morbid procedure. Sentinel lymph node (SLN) should avoid extensive lymphadenectomy in node negative patients. The aim of this prospective study is to determine the feasibility and usefulness of lymphatic mapping and SLN identification in the management of endometrial cancer.

Further data on sentinel lymph node mapping in vulvar cancer by blue dye and radiocolloid Tc99.

We studied the distribution of sentinel lymph nodes (SLNs) in vulvar cancer using blue dye and (99m)Tc radiocolloid and evaluated the techniques used, including the optimum timing of preoperative scintigraphy scans and its contribution to (99m)Tc SLN detection over that of the intraoperative handheld gamma probe. Fifty-nine women with squamous cell cancers <4 cm treated at our institution between December 2001 and December 2005 were included in this study. Blue dye alone was used in the first 16 women (group A) and the combination of (99m)Tc and blue dye was used on 43 women (group B).
