SummaryA total of 21 patients suffering from drug-induced rashes from practolol have been seen over the past two years. The clinical manifestations varied, with the morphological appearances of the rash resembling those of eczema, lupus erythematosus, lichen planus, and a highly characteristic toxic erythematous psoriasiform eruption. Persistent ocular damage was a feature in three cases.

The L/T at helical CT provide an accurate assessment of reactive versus malignant nodes in the head and neck.

Summary To assess the accuracy of multirow detector computed tomography (MDCT) for the evaluation of renal anatomy for preoperative donor assessment in living related kidney transplantation. MDCT‐scans (4‐ and 16‐slice‐CT) of 51 consecutive living kidney donors (age, 51.6 ± 9.7 years; range, 28–68 years) were analysed by three blinded observers and compared with digital subtraction angiography (DSA) and surgery. Contrast‐enhanced MDCT was performed with 1 mm slice thickness reconstruction interval during arterial and venous phases. Supernumerary renal arteries, veins, early branching of vessels and abnormalities of the ureters were documented. The overall accuracy of computed tomography angiography (CTA) for detection and classification of surgically relevant arterial variants was 97% (99/102). The interpretation of 16‐channel MDCT images was correct in all cases (accuracy, 100%), while the four‐channel CTA had three incorrect results regarding the differentiation of early branching vessels from double renal arteries (accuracy, 93%). The overall accuracy of DSA was 91%. Renal vein abnormalities were correctly diagnosed with MDCT in 100% compared with 89% correct findings with DSA. There were three kidneys with incomplete ureter duplication, detected both with MDCT and DSA. MDCT demonstrated superior accuracy compared with non‐selective DSA for the preoperative assessment of renal anatomy in living kidney donors; and for the distinction of supernumerary arteries versus early branching patterns, 16‐channel CTA data were better than those of the four‐channel system.

Dynamic gadobenate dimeglumine-enhanced MR imaging allows improved characterization of HCC lesions, which show rapid increase in signal intensity during the early, arterial phase in well-differentiated HCC lesions and a double-ring sign in large well-differentiated nodular HCC lesions.

For the differentiation of primary brain tumours the single dose was sufficient, in metastatic lesions triple dose was essential for the detection or exclusion of multifocality.
