We report the case of a 45-year-old man with advanced hepatocellular carcinoma (HCC) who was able to undergo radical surgery after repeated transarterial therapy. Transarterial chemoembolization was repeated three times, and thereafter, transarterial infusion chemotherapy using Lipiodol was performed on the right hepatic artery. Because notable atrophy of the right lobe and compensated hypertrophy of the left lobe were detected after this therapy, an extended right lobectomy could be performed. Histologically, the HCC showed complete necrosis. The remarkable atrophic change of the right lobe was thought to be due to an obstruction of the right portal veins by the spread of inflammation around the bile duct necrosis, in addition to the narrowing of the hepatic artery. A thorough understanding of this phenomenon and the development of methods to clinically apply it in the treatment of cancer patients may thus lead to an increase in the percentage of resectable cases of advanced HCC.
The cognitive architecture and neural underpinnings of different semantic domains remains highly controversial. We report two patients with focal temporal lobe atrophy who presented with contrasting and theoretically informative dissociations of person-specific versus general semantic knowledge. Subject J.P. showed severely impaired person-specific semantics, with relative preservation of knowledge about objects and animals, while subject M.A. exhibited the opposite pattern of performance (good knowledge of people in the context of impoverished general semantics). Voxel-based morphometric analysis of MR images in the two cases established predominantly right temporal atrophy associated with J.P.'s deficit for person knowledge and predominantly left temporal atrophy in M.A. who was impaired in general conceptual knowledge.
OBJECTIVE: Voiding dysfunction is more frequent in primary progressive multiple sclerosis (PPMS) than in other subtypes of MS. We investigated whether lower urinary tract disorders are reflected in the extent of changes in brain and spinal cord detected by magnetic resonance imaging (MRI). METHODS: Micturition symptoms and specific urodynamic findings in 24 patients with PPMS were related to MRI abnormalities as analysed by segmentation and volumetric analysis. RESULTS: Urgency and urge incontinence were the most frequent urinary symptoms (83 and 75 %), while detrusor sphincter dyssynergia (DSD) (71%), detrusor hyperreflexia (58%) and obstruction (58%) were the most common micturition dysfunctions. Comparison between patients with detrusor hyperreflexia and those with normal bladder function revealed higher volumes of T2-weighted plaques in the brains of former (P = 0.01). In patients with hypotonic bladder the total brain volume was smaller (P = 0.02) and the number of thoracic plaques in T2-weighted images higher (P = 0.02) compared to patients with normal bladder function. Furthermore, DSD was associated with a higher volume of T2-weighted plaques in the brain (P = 0.02). CONCLUSIONS: Voiding dysfunction in PPMS is associated with increasing brain and spinal cord abnormalities. Urodynamic investigation is, however, needed for specific definition of micturition disturbances and should be made before therapeutic decisions.
