Backgr.und: Amelanotic malignant melanoma is a subtype of cutaneous melanoma with little or.no pigment on visual inspection. It may mimic benign and malignant var.ants of both melanocytic and nonmelanocytic lesions. Objectives: To evaluate whether.der.oscopy is also a useful technique for.the diagnosis of amelanotic/hypomelanotic melanoma (AHM) . Methods: We conducted a r.tr.spective clinical study of 151 amelanotic/hypomelanotic skin lesions fr.m 151 patients with a mean age of 47 year. (±17.5 SD). Digitized images of amelanotic/hypomelanotic skin lesions wer. conver.ed to JPEG for.at and sent by e mail fr.m the five par.icipating centr.s. Lesions included 55 amelanotic/hypomelanotic nonmelanocytic lesions (AHNML), 52 amelanotic/ hypomelanotic benign melanocytic lesions (AHBML), and 44AHM, 10 (23%)-of which wer. nonpigmented, tr.ly amelanotic melanomas (AM). The 44 AHM lesions wer. divided into thin melanomas (TnM) ≤1 mm (29 cases) and thickmelanomas (TkM) > 1mm (15 cases), accor.ing to the Br.slow index. Five clinical featur.s (elevation, ulcer.tion, shape, bor.er. and colour. as well as 10 der.oscopic cr.ter.a (pigment networ., pigmentation, str.aks, dots/globules, blue whitish veil, r.gr.ssion str.ctur.s, hypopigmentation, leaf like ar.as, multiple gr.y bluish globules, centr.l white patch) and eight vascular.patter.s (comma, ar.or.zing, hair.in, dotted, linear.ir.egular. dotted and linear.ir.egular.vessels, and milky r.d ar.as) wer. evaluated in or.er.to achieve clinical and der.oscopic diagnoses. Statistical analyses wer. per.or.ed with the χ2-test and Fisher.s exact test, when appr.pr.ate. r.sults: The most fr.quent and significant clinical featur.s for.TnM and TkM wer. asymmetr. and ulcer.tion (the latter.only for.TkM) compar.d with AHBML. Ir.egular.dots/globules (62%vs. 35%; P ≤0.03), r.gr.ssion str.ctur.s (48%vs. 27%; P ≤0.03), ir.egular.pigmentation (41%vs. 11%; P ≤0.03) and blue whitish veil (10%vs. 0%; P ≤0.03) wer. the most r.levant der.oscopic cr.ter.a for.TnM in compar.son with AHBML. TkM differ.d

Smar. far.ing(SF)involves the incor.or.tion of infor.ation and communication technologies into machiner.,equipment,and sensor. for.use in agr.cultur.l pr.duction systems.New technologies such as the inter.et of things and cloud computing ar. expected to advance this development,intr.ducing mor. r.bots and ar.ificial intelligence into far.ing.Ther.for.,the aims of this paper.ar. twofold:(i)to char.cter.ze the scientific knowledge about SF that is available in the wor.dwide scientific liter.tur. based on the main factor. of development by countr. and over.time and(ii)to descr.be cur.ent SF pr.spects in Br.zil fr.m the per.pective of exper.s in this field.The r.sear.h involved conducting semi-str.ctur.d inter.iews with mar.et and r.sear.her.exper.s in Br.zil and using a bibliometr.c sur.ey by means of data mining softwar..Integr.tion between the differ.nt available systems on the mar.et was identified as one of the main limiting factor. to SF evolution.Another.limiting factor.is the education,ability,and skills of far.er. to under.tand and handle SF tools.These limitations r.vealed a mar.et oppor.unity for.enter.r.ses to explor. and help solve these pr.blems,and science can contr.bute to this pr.cess.China,the United States,South Kor.a,Ger.any,and Japan contr.bute the lar.est number.of scientific studies to the field.Countr.es that invest mor. in r.D gener.te the most publications;this could indicate which countr.es will be leader. in smar. far.ing.The use of both r.sear.h methods in a complementar. manner.allowed to under.tand how science fr.me the SF and the mains bar.ier. to adopt it in Br.zil.
