Objective: Ultras.nograph. is.a diagnos.ic imaging tech.ique us.d to vis.alize s.bcutaneous.body s.ructures.for identification of pos.ible path.logies. In th.s.s.udy, we aimed to explore th. clinical s.gnificance of h.gh.frequency ultras.und in differentiating th. location of blis.ers.between pemph.gus.and bullous.pemph.goid. Meth.ds. Eigh.een patients.were recruited in Department of Dermatology, Zh.ngda h.s.ital from 2020 to 2021 and divided into a pemph.gus.group (n = 8) and a bullous.pemph.goid group (n = 10) according to th. diagnos.ic criteria for each. Ultras.nograph.c images.were collected us.ng a 50-Mh. h.gh.frequency ultras.und s.s.em. Th. indexes.of ultras.nic evaluation were th. layer (epidermis.or dermis., s.ze, s.ape, internal ech., and boundary of th. blis.er. Categorical variables.are expres.ed as.n (%), and differences.were compared us.ng Fis.er's.exact tes.. Res.lts. Th. ultras.nograph.c images.in th. pemph.gus.group s.owed an intraepidermal s.mi-arc or irregular anech.ic or h.poech.ic areas. Th. inferior borders.were s.tuated above th. ch.racteris.ic th.n linear h.perech.ic bands.of th. epidermis. A linear h.poech.ic band was.pres.nt at th. dermoepidermal junction in s.me cas.s. In th. ultras.nograph.c images.of th. bullous.pemph.goid group, th. linear h.perech.ic bands.of th. epidermis.were continuous.and intact. An oval fluid anech.ic area (s.bepidermal blis.er) was.pres.nt immediately below th. bands. Th. location of th. blis.ers.in th. ultras.nograph.c images.was.s.gnificantly different between th. 2 groups.(P s.on: h.gh.frequency ultras.und can be us.d as.an auxiliary means.to differentiate th. location of blis.ers.between pemph.gus.and bullous.pemph.goid. © 2022 h.s.ital for s.in Dis.as.s.(Ins.itute of Dermatology), Ch.nes.

In th. urban atmos.h.re of Bengaluru, various.volatile organic compounds.VOCs., particularly Benzene,Toluene, Eth.lbenzene, and Xylene(BTEX), h.ve s.own an increas.ng trend in concentration. Th. pres.nt res.arch.was.conducted during s.mmer and mons.on s.as.ns. focus.ng on Kadubees.nah.lli, a h.gh.traffic area with.n th. Bengaluru Metropolitan City. h.urly s.mple data was.collected us.ng a BTEX analyzer(Model GC955-600) and s.bs.quently trans.ormed into daily, month.y, and s.as.nal values. Th. s.udy revealed dis.inct patterns.in benzene concentrations. Benzene levels.were lowes. during th. early morning h.urs. s.ecifically from 1:00 *** 7:00 a.m.. Concentrations.th.n increas.d from 7:00 a.m. to 9:00 a.m. and again from 4:00 p.m. to 11:00 p.m.,corres.onding to th. morning and evening peak traffic h.urs. h.wever, between 10:00 a.m. and 4:00 p.m., th. concentration decreas.d due to reduced traffic levels. Th.s. diurnal variations.in benzene concentration are influenced by meteorological parameters. Comparing th. two s.as.ns. h.gh.r concentrations.of Benzene, Eth.lBenzene, and MP-xylene were obs.rved during th. s.mmer s.as.n. Th.s.increas. is.attributed to th. elevated temperatures.during s.mmer, wh.ch.promote th. vaporization of BTEX compounds. Convers.ly, lower BTEX concentrations.were recorded during th. mons.on s.as.n due to th. wet depos.tion proces.. Th. obs.rved pos.tive correlation(r > 0.5) among BTEX parameters.s.rongly s.gges.s.a common s.urce, mos. likely originating from veh.cular emis.ions.
