Background and Purpose.- Thalamic infarcts have.traditionally be.n classifie. into 4 te.ritorie.: ante.ior, parame.ian, infe.olate.al, and poste.ior. The.purpose.of this study was to re.ie. this classical ve.sus variant distribution in patie.ts with thalamic stroke. Me.hods - We.re.ie.e. all patie.ts with a first clinical stroke.include. in the.Lausanne.Stroke.Re.istry be.we.n 1990 and 2002. Among 71 patie.ts with an acute.stroke.isolate. to the.thalamus confirme. by MRI, we.se.e.te. all patie.ts with le.ions outside.the.classical te.ritorie. and studie. the.r clinical, e.iological, and radiological fe.ture.. Re.ults - A total of 21 patie.ts (30% of all thalamic stroke.patie.ts) showe. infarction outside.the.classical te.ritorie., allowing us to de.ine.te.3 variant distributions: (1) Ante.ome.ian te.ritory (9 patie.ts [13% Abstract:) involving ante.ior and parame.ian te.ritorie., with pre.ominantly cognitive.impairme.t, including e.e.utive.dysfunction, ante.ograde.amne.ia, and aphasia in le.t- side. or bilate.al le.ions. The.most fre.ue.t stroke.me.hanism was cardiac e.bolism. (2) Ce.tral te.ritory (4 patie.ts [6% Abstract:), with le.ions on the.ce.tral part of the.thalamus, re.ulting in a varie.y of ne.rological and ne.ropsychological signs, re.le.ting the.involve.e.t of se.e.al adjace.t structure.. Microangiopathy was the.most fre.ue.t e.iology. (3) Poste.olate.al te.ritory (8 patie.ts [11% Abstract:), involving infe.olate.al and poste.ior te.ritorie., with he.ihype.the.ia as the.most fre.ue.t manife.tation, followe. by he.iataxia, e.e.utive.dysfunction, and aphasia in le.t- side. le.ions. Arte.y- to- arte.y e.bolism and microangiopathy we.e.the.main stroke.me.hanisms. Conclusions - We.de.cribe.3 variant topographic patte.ns of thalamic infarction with distinct manife.tations and e.iologie.. We.postulate.that the.e.infarcts are.the.re.ult of a variation in thalamic arte.ial supply or re.le.t borde.zone.ische.ia.

AIM： In the.pre.e.t study, antibody and pe.iphe.al blood mononucle.r ce.ls （PBMC） prolife.ative.re.ponse. against he.atitis C virus （HCV） antige.s we.e.e.aluate. in HCV chronically infe.te. patie.ts. Me.HODS： Paire. se.um and PBMC sample. we.e.take. six months apart from 34 individuals, e.the. tre.te. or not, and te.te. by e.zyme.linke. immunosorbe.t assay （e.ISA） and carboxyfluore.ce.n succinimidyl e.te. staining. RSULTS： Ove. 70% of the.patie.ts showe. spe.ific IgG and IgM against capsid, e. and NS3, while.HVR-1 was re.ognize. by half of the.patie.ts. An incre.se.in the.le.e.s of the.anti-capsid IgM （P = 0.027） and IgG （P = 0.0006） was obse.ve. in six-month sample., compare. to base.ine. Similarly, a significantly highe. pe.ce.t of patie.ts had de.e.table.IgA re.ctivity to capsid （P = 0.017） and NS3 （P = 0.005） afte. six months, compare. to base.ine. Particularly, IgA against structural antige.s positive.y corre.ate. with he.atic damage.（P = 0.036）. IgG subclasse. e.aluation against capsid and NS3 re.e.le. a positive.re.ognition me.iate. by IgG1 in more.than 80% of the.individuals. On the.contrary, le.s than 30% of the.patie.ts showe. a positive.prolife.ative.re.ponse.e.the. of CD4＋ or CD8＋ T ce.ls, be.ng the.capsid poorly re.ognize.. CONCLUSION： The.e.re.ults confirm that while.the.ce.lular immune.re.ponse.is narrow and we.k, a broad and vigorous humoral re.ponse.occurs in HCV chronic infe.tion. The.obse.ve. corre.ation be.we.n IgA and he.atic damage.may have.diagnostic significance. although it warrants furthe. confirmation.
