Reversible findings of restricted diffusion in 5‐flourouracil neurotoxicity

A 35‐year‐old woman presented with neurotoxicity correlated to an i.v. regimen of 5‐fluorouracil as episodes of acute confusional state and abnormalities of symmetrically restricted diffusion in the periventricular white matter and corpus callosum. On discontinuing the medication, the areas of severely restricted diffusion had entirely resolved, with minimal residual T2 signal abnormality. In this case, immediate discontinuation of the chemotherapeutic agent apparently reversed the patient's symptoms and findings on MRI. The scant information available in the published literature regarding this phenomenon is reviewed with regard to 5‐fluorouracil.     

在非裔美国人中用1％吡美莫司软膏治疗伴色素减退的脂溢性皮炎的先导性试验

背景:非裔美国人发生脂溢性皮炎时可伴色素减退。治疗通常应用皮质激素和抗真菌药,然而长期使用皮质激素可导致皮肤萎缩,眼内压增高,或加重色素减退。吡美莫司已被成功用于治疗一些脂溢性皮炎患者。目的:此开放性预试验用于评估吡美莫司治疗非裔美国人中伴色素减退的脂溢性皮炎     

Familial Nephropathic Non-neuropathic Amyloidosis: Clinical Features, Immunohistochemistry and Chemistry

Classification of familial amyloidosis by the chemical natureof the fibrillar protein has become possible. Most such amyloidogenicproteins so far recognized are variant transthyretins, but twokindreds with the same apolipoprotein AI modification have beenreported. We describe the clinical features of another suchfamily in whom petechial skin rash appeared to be a marker forthe disease, which was non-neuropathic and of the Ostertag-type.Immunohistochemistry showed the protein to be apolipoproteinAI, but allele-specific DNA amplification indicated that itwas not the Arg²⁶ variant previously identified.
