Automatic detection of lung nodules in CT datasets based on stable 3D mass–spring models
2012
We propose a computer-aided detection (CAD) system which can detect small-sized (from 3 mm) pulmonary nodules in spiral CT scans. A pulmonary nodule is a small lesion in the lungs, round-shaped (parenchymal nodule) or worm-shaped (juxtapleural nodule). Both kinds of lesions have a radio-density greater than lung parenchyma, thus appearing white on the images. Lung nodules might indicate a lung cancer and their early stage detection arguably improves the patient survival rate. CT is considered to be the most accurate imaging modality for nodule detection. However, the large amount of data per examination makes the full analysis difficult, leading to omission of nodules by the radiologist. We…
Focal elevation of liver microsomal epoxide hydrolase in early preneoplastic stages and its behaviour in the further course of hepatocarcinogenesis.
1981
Abstract Treatment of rats with N-nitrosomorpholine (NNM) for 7 weeks led to a focal increase in liver microsomal epoxide hydrolase (EH) as early as 2 weeks after withdrawal of the carcinogen. This treatment also leads to hyperplastic nodules and liver tumors, but much later. At the same early time point, ATPase activity was decreased in the same islands. Most of these areas already had increased γ-glutamyltranspeptidase activity. The increase in EH at this early time point was more distinct than the decrease in ATPase which has thus far been considered a suitable marker of the earliest stages in hepatocarcinogenesis. The focal increase in EH was also observed in all benign hepatomas, but n…

Treatment of relapsing idiopathic nodular panniculitis (Pfeifer-Weber-Christian disease) with mycophenolate mofetil
1998
Idiopathic nodular panniculitis (Pfeifer-WeberChristian disease) is characterized by fever and symmetric subcutaneous nodules often located on the lower extremities.1,2 Histologically, a lobular panniculitis with a pronounced neutrophilic infiltrate is observed. The course of the disease is characterized by acute onset with fever and malaise and the simultaneous appearance of painful subcutaneous nodules. Some patients experience involvement of the intra-abdominal or retroperitoneal fat. Relapses are frequent, and a fatal outcome has been described repeatedly. Therapy usually consists of steroids in medium to high dosages, as well as immunosuppressive drugs such as azathioprine or methotrex…
Para-aortic lymphadenectomy in abnormal common iliac bifurcation
2021
A 60-year-old-woman was diagnosed with serous endometrial cancer and on pre-operative CT there was evidence of a higher confluence of the common iliac veins in the inferior vena cava ([Figure 1][1]). Due to the presence of ascites (800 mL) and of a neoplastic ileal nodule at laparoscopy, to avoid
MILKER’S NODULE. A PERPLEXING FARMYARD INFECTION AND THREAT TO THE IMMUNOCOMPROMISED
2017
Milker’s nodules, also called paravaccinia, is a DNA virus transmitted from infected cows to humans. It results from contact with cattle, cattle byproducts, or fomites. Classified as an occupational disorder, those at risk of exposure include farmers, butchers, and agricultural tourists. The viral infection begins 5—15 days after inoculation as an erythematous-purple, round nodule with a clear depressed center, and a surrounding erythematous ring. While familiar to those in farming communities, the presence of the nodule may be concerning to others, particularly the immunosuppressed. Milker’s nodules are selflimited in immunocompetent individuals and heal without scarring within 8 weeks. An…
