Axillary sonography is moderately sensitive and fairly specific in the diagnosis of axillary metastatic involvement. Sonographically guided biopsy of the sonographically suspicious nodes somewhat increases the specificity, which reaches 100%. Negative sonographic results do not exclude axillary lymph node metastases.

The aim of the present study was to examine the effects of green tea epigallocatechin-3-gallate (EGCG) on changes in body composition, energy and substrate metabolism, cardiometabolic risk factors and liver function enzymes after an energy-restricted diet intervention in obese women. In the present randomised, double-blind, placebo-controlled study, eighty-three obese (30 kg/m 2 . BMI , 40 kg/m 2 ) premenopausal women consumed 300 mg/d of EGCG or placebo (lactose). We measured body weight and adiposity (dual-energy X-ray absorptiometry), energy expenditure and fat oxidation rates (indirect calorimetry), blood lipid levels (TAG, total cholesterol, LDL-cholesterol and HDL-cholesterol), insulin resistance, C-reactive protein and liver function markers (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, g-glutamyltransferase, urea, bilirubin and 2-keto[1-13 C]isocaproate oxidation) before and after the intervention in the EGCG and control groups. We did not find any significant difference in the changes in body weight (2 0·3 kg, 95 % CI 25·0, 4·3), fat mass (2 0·7 kg, 95 % CI 23·5, 2·1), energy (0·3 kJ/kg per d, 95 % CI 2 3·1, 2·7) and fat (20·1 g/min, 95 % CI 2 0·03, 0·01) metabolism, homeostasis assessment model for insulin resistance (0·2, 95 % CI 2 0·2, 0·7), total cholesterol (20·21 mmol/l, 95 % CI 20·55, 0·13), LDL-cholesterol (2 0·15 mmol/l, 95 % CI 20·50, 0·20), TAG (2 0·14 mmol/l, 95 % CI 20·56, 0·29) and liver function markers between the EGCG and control groups. In conclusion, the present results suggest that dietary supplementation with 300 mg/d of EGCG for 12 weeks did not enhance energy-restricted diet-induced adiposity reductions, and did not improve weight-loss-induced changes in cardiometabolic risk factors in obese Caucasian women. The intake of 300 mg/d of EGCG for 12 weeks did not cause any adverse effect on liver function biomarkers.

A 61-year-old-man with persistent anemia was referred for a Tc-99m-labeled red blood cell (RBC) scan to detect any source of gastrointestinal bleeding. RBC scintigraphy revealed a hypervascular mass in the left renal fossa with functional loss in that kidney, suggesting the possibility of a renal cell carcinoma (RCC). Computed tomography confirmed this. Most RCC tumors are hypervascular on conventional angiography, with a maximum incidence in men in the sixth decade. The incidental diagnosis of RCC during radionuclide imaging has been documented in previous reports, but the authors are not aware of any case of RCC diagnosed during a RBC scan. This case illustrates the importance of careful attention to the appearance of the kidneys on radionuclide scans. Noticeable asymmetric renal activity in a patient without known renal parenchymal disease warrants further investigation.
