Cranioplasty appears to affect postural blood flow regulation, CVR capacity, and cerebral glucose metabolism markedly. Thus, early cranioplasty is warranted to facilitate rehabilitation in patients after decompressive craniectomy.
Fourteen drug-naive and 11 levodopa-treated patients with idiopathic restless legs syndrome (RLS), and 10 controls age-matched to each RLS group separately were examined with polysomnography (PSG), [(123)I]-(N)-(3-iodopropen-2-yl)-2beta-carbomethoxy-3beta-(4-chlorophenyl) tropane ((123)I-IPT) SPECT, and [(123)I]-(S)-2-hydroxy-3-iodo-6-methoxy-[(1-ethyl-2-pyrrolidinyl)methyl] benzamide ((123)I-IBZM) SPECT. Drug-naive and levodopa-treated patients with RLS and controls showed similar striatal dopamine transporter and dopamine D(2)-receptor binding, the latter declining with age. The authors conclude that striatal dopamine transporter and receptor density is normal in drug-naive and levodopa-treated patients with RLS.
Abstract. Most of the adrenal tumors that are incidentally detected are benign adenomas. The incidence of malignant adrenal tumors including adrenocortical carcinoma (ACC) and primary adrenal lymphoma (PAL) is rather low. As many patients with ACC and PAL are diagnosed at an advanced stage of disease, the overall survival time of both entities remains poor. The therapeutic strategies for both entities differ. Thus an early differentiation between ACC and PAL is necessary. Unfortunately hitherto preoperative diagnosis of potentially malignant adrenal masses is still a main problem in the treatment of adrenal tumors. We present the case of a 57-year-old male patient with ACC and the case of an 87-year-old male patient with PAL and provide a systematic comparison of the clinical and pathological features of both entities. In both cases clinical and radiological features resulted in an initially false diagnosis. Primary surgical therapy was performed in both patients. The patient with PAL died five months aftre initial surgery. The patient with ACC showed tumor progression with local and systemic recurrence despite adjuvant therapy with mitotane and additional surgical therapy. Prognosis of patients with ACC and PAL seems to be dependant on the ability to start accurate treatment without any time delay. We propose some guidelines for diagnosis and surgical management of adrenal tumors.
FDG-PET imaging is useful in tumor screening of patients with antineuronal antibodies, but should be complemented by CT scanning to increase sensitivity and accuracy of tumor diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
