Knowledge about the biological variability of anatomical objects is essential for statistical shape analysis and discrimination between healthy and pathological structures. This paper describes a novel approach that incorporates the variability of an object population into the generation of a characteristic 3D shape model. The proposed shape representation is a coarse-scale sampled medial descr...

PURPOSE We investigated the pathways of spread of odontogenic infection in the facial and neck spaces. METHODS CT scans of 45 patients with extensive spread of odontogenic infection into the facial and neck spaces were analyzed to document pathways of spread. RESULTS Odontogenic infections arising in the mandible first spread upward, into the masseter and/or medial pterygoid muscles in the ...

BACKGROUND It is important to evaluate dynamic changes in the joint space width of the ankle mortise in detail in order to better understand the pathology of foot and ankle disorders. However, there are few reports on changes in the joint space width of the foot and ankle assessed using 3D images. The purpose of this study was to determine the changes in the joint space width of the ankle (tibi...

CONTEXT Sarcomatous differentiation, which represents transformation to high-grade malignancy, can occur in all histological types of renal malignancy. CASE REPORT The authors report on the case of a 66-year-old woman with a right renal mass that was shown to be a clear cell carcinoma. She underwent radical nephrectomy and dendritic cell vaccination and, 3.5 years later, she developed retrope...

results three hundred patients were eligible for the study. after 1 month, 62% of patients (186 patients) reported good pain relief [95% confidence interval (ci) 0.53, 0.7]; 8.6% (26 patients) reported excellent pain relief (95% ci 0.07-0.09); 20. 4% (61 patients) reported poor pain relief (95% ci 0.18-0.22), and 9% (27 patients) reported no pain relief (95% ci 0.08-0.099). the average pain num...

BACKGROUND Hepatocellular carcinoma (HCC) is a major cause of cancer-related mortality worldwide and the incidence is increasing as a result of growing hepatitis B and C virus infections. Primary clear cell carcinoma of the liver (PCCCL) is a rare subgroup of primary HCC, which has low metastatic potential and infrequently reported in literature. Retroperitoneal and intrahepatic metastasis of P...
