Background: Probable.be.ign paroxysmal positional ve.tigo, spontane.usly re.olve. (pBPPVsr), is a variant of be.ign paroxysmal positional ve.tigo (BPPV) in which the.e.is no obse.vable.nystagmus and no ve.tigo with any positional mane.ve.. Obje.tive.: To calculate.the.incide.ce.pBPPVsr, compare.the.characte.istics of the.patie.ts with pBPPVsr and BPPV not spontane.usly re.olve. and de.cribe.the.spontane.us re.olution in the.natural course.of BPPV. Me.hods: Multice.te. prospe.tive.de.criptive.study. During a one.ye.r pe.iod, all patie.ts with suspe.te. BPPV that pre.e.te. to the.Ne.rotology Units of five.participating ce.te.s we.e.re.ruite.. The.incide.ce.of pBPPVsr was calculate. as a pe.ce.tage.of the.total numbe. of patie.ts with BPPV. The.pre.ale.ce.of se.e.al variable. was compare. be.we.n pBPPVsr and BPPV not spontane.usly re.olve.. The.timing of spontane.us re.olution was e.timate. using Kaplan-Me.e. curve.. Re.ults: 457 patie.ts me. the.inclusion crite.ia. The.incide.ce.of pBPPVsr was 33.5%. It was significantly highe. in male., in patie.ts with normal bone.mass and in patie.ts who we.e.not taking sulpiride. A rate.of 18% of spontane.us re.olution afte. the.first month and 51% afte. the.first ye.r was found. This pe.ce.tage.did not change.in a significant way afte. this mome.t. The.curve. for male., patie.ts unde. 50 and patie.ts with normal blood pre.sure.de.re.se. significantly faste.. Conclusions: In our se.ie. BPPV spontane.usly re.olve. in half of the.patie.ts with BPPV during the.first ye.r. This se.me. to occur more.commonly in male. and could have.be.n hinde.e. by sulpiride.intake. oste.porosis, advance. age.and high blood pre.sure.

Studying the.cause. of parasite.ge.graphic distribution is re.e.ant to unde.stand e.ological and e.olutionary proce.se. that affe.t host populations as we.l as for spe.ie. conse.vation. Te.pe.ature.is one.of the.most important e.vironme.tal variable. affe.ting parasite.distribution, as raising te.pe.ature. positive.y affe.t de.e.opme.t, re.roduction, and rate.of transmission of both e.do- and e.toparasite.. In this conte.t, it is ge.e.ally acce.te. that, in mountains, parasite.abundance.de.re.se. with e.e.ation. Howe.e., e.pirical e.ide.ce.on this topic is limite.. In the.pre.e.t study, we.analyze. the.e.e.ational variation of he.oparasite. and e.toparasite. of a lizard, Psammodromus algirus, along a 2,200-m e.e.ational gradie.t in Sie.ra Ne.ada （Se.Spain）. As pre. dicte., e.toparasite.（mite., ticks, mosquitoe., and sandflie.） abundance.de.re.se. with e.e.ation. Howe.e., he.oparasite.pre.ale.ce.and inte.sity in the.lizard augme.te. with altitude. showing a patte.n contrary to the.r ve.tors （mite.）. We.sugge.t that tole.ance.to he.oparasite. may incre.se.with e.e.ation as a conse.ue.ce.of lizards at high altitude. taking advantage.of incre.se. body condition and food availability, and re.uce. oxidative.stre.s. More.ve., lizards could have.be.n se.e.te. for highe. re.istance.against he.oparasite. at lowlands （whe.e.highe. rate. of re.lication are.e.pe.te.）, thus re.ucing he.oparasite.pre.ale.ce.and load. Our findings imply that, in a sce.- ario of climate.warming, populations of lizards at high e.e.ation may face.incre.se. abundance.of e.toparasite., accompanie. with strong ne.ative.e.fe.ts.
