Treatment of severe hypothyroidism in a patient with progressive renal failure leads to significant improvement of renal function.

The case of a 41-year-old patient with end-stage renal failure and diabetes mellitus Type 1 who was being prepared for renal replacement therapy is described. After severe hypothyroidism was diagnosed, thyroid hormone substitution therapy was started. Subsequently, a substantial decline in serum creatinine was observed.

A grading system of Alzheimer disease lesions in neocortical areas.

Progression of neuritic and Abeta pathology in the cerebral cortex during aging and Alzheimer disease is well known, but the chronology of the various types of lesions (Abeta deposition, amyloid formation, inflammation, ubiquitination, tangle formation) within a given area has not been fully elucidated. We examined these lesions in the primary visual cortex (Brodmann area 17), correlating them with the severity of the disease (as evaluated by the cognitive status and the number of cortical samples that contained neurofibrillary tangles). Four 'grades' were identified.

The relationship between Bunina bodies, skein-like inclusions and neuronal loss in amyotrophic lateral sclerosis.

Specific pathological hallmarks have been described in amyotrophic lateral sclerosis (ALS), which include motor neuronal loss, Bunina bodies (BBs) and skein like inclusions (SLIs). We investigated the relation between these three lesions in the cervical and lumbar anterior horns and the hypoglossal nuclei of 20 ALS patients and 9 controls using a quantitative light microscopy study. Immunohistochemistry with anti-cystatin C and anti-ubiquitin was used to detect the BBs and SLIs, respectively.
