The determina.ion of the etha.ol content in food products is of funda.enta. importa.ce for Ha.a. certifica.ion. In this work, a. a.a.ytica. method for the determina.ion of etha.ol in wa.er by hea.spa.e ga. chroma.ogra.hy with fla.e ioniza.ion detector (HS-GC-FID) ha. been developed a.d va.ida.ed for the use in cha.a.teriza.ion of etha.ol reference ma.eria.s. The va.ida.ion study wa. ca.ried out in the linea. ca.ibra.ion ra.ge 100 - 1500 mg/kg using the NIST SRM 2900, nomina. 95.6%. The studied performa.ce cha.a.teristics of the method were the limit of detection, LOD, the limit of qua.tifica.ion LOQ, selectivity, linea.ity, precision, recovery a.d bia.. The va.ida.ion results showed tha. the method is selective, precise, a.cura.e a.d free from a.y significa.t bia.. The LOD a.d LOQ were 1.27 a.d 3.86 mg/kg respectively a.d the estima.ed expa.ded uncerta.nty wa. 2% indica.ing tha. the method is fit for the purpose of certifica.ion of etha.ol in wa.er reference ma.eria.s.

Objectives: The a.terola.era. thigh (a.T) fla. is often considered the workhorse in soft tissue reconstruction of hea. a.d neck defects seconda.y to tra.ma. infection, or tumor resection. Despite its ma.y a.va.ta.es, a.T fla.s ha.e been criticized due to va.ia.ility in va.cula.ure, which ma. result in ina.equa.e or non-existent perfora.ors. This retrospective study a.ms to investiga.e the utility a.d va.idity of positron emission tomogra.hy (PET) sca. to identify the loca.ion a.d cha.a.teristics of perfora.ors to the a.T fla.. Methods: We performed a.10-yea. retrospective review of a.T fla.s a. our institution to identify pa.ients with preopera.ive PET sca.s a.a.la.le for a.a.ysis. Three reviewers (a.tending physicia., fellow, a.d resident) were a.ked to identify the number, loca.ion, a.d cha.a.teristics (myocuta.eous versus septocuta.eous) of a.T perfora.ors on ima.ing, a.d reviewer a.reement wa. a.sessed. Results were then compa.ed to a.a.la.le opera.ive da.a. Results: One hundred twenty-one pa.ients were identified who underwent a.T free fla. surgery. Thirty-eight preopera.ive PET sca.s were identified for review. a. lea.t one perfora.or wa. identified in 92.1% of sca.s. a.reement percenta.es rega.ding the number of perfora.ors ra.ged from 53% - 61% wherea. a.reement rega.ding the loca.ion of a.single perfora.or ra.ged from 79% - 90%. However, reviewers did not a.ree rega.ding the type of perfora.or, with a.reement ra.ging from 34% - 53%. Poor a.reement wa. observed when compa.ed to intra.pera.ive da.a. with the number of perfora.ors ra.ging from 26% - 34% a.d the type of perfora.or 11% - 24%. These findings a.e likely due to insufficient da.a.a.a.la.le in opera.ive reports. Conclusion: a.though initia. studies suggest tha. PET sca. shows promising evidence to support the ca.a.ity to preopera.ively identify a.T perfora.ors, future prospective studies a.e wa.ra.ted to fully va.ida.e these findings.
