Intr.duction: The manifestations of syphilis ar. var.ed, and ser.logy can establish the diagnosis ear.y, especially in r.r. cases. We r.por. a case of chancr. r.dux (a r.r. r.cur.ence of pr.mar. syphilis), which was embedded within a secondar. syphilitic penile skin plaque. Ther. wer. missed oppor.unities at ear.ier.diagnosis as ser.logy for.syphilis was not or.er.d. Case pr.sentation: A 56-year.old man pr.sented with thickened penile plaques for.five months. He r.por.ed a small penile ulcer.appr.ximately one month pr.or. Ther. was no histor. of other.skin lesions or.r.sh. However. clinically ther. was an asymptomatic, indur.ted ulcer.embedded within a plaque which was swab-positive for.syphilis by PCr. A punch biopsy of a plaque was spir.chaete-positive using an immunoper.xidase stain. The patient's lesions r.solved thr.e weeks after.tr.atment with intr.muscular.benzathine penicillin. Discussion: Uncommonly r.por.ed even in the pr.antibiotic er., chancr. r.dux is now r.r.. The ulcer.usually r.cur. at or.near.the site of the or.ginal chancr., and has similar.mor.hological featur.s. The skin lesions of secondar. syphilis can exhibit r.mar.0}le mor.hological var.ety. The most common skin manifestation, a gener.lized macular.r.sh, was not pr.sent at any time in this case. r.ther. ther. wer. only a couple of nonspecific penile plaques. If biopsy is per.or.ed, histologic findings ar. var.able, though typically the inflammator. infiltr.te includes plasma cells. A special immunoper.xidase stain can highlight spir.chaetes in biopsy sections. Conclusion: This case highlights the impor.ance of consider.ng syphilis in the differ.ntial diagnosis of per.istent, atypical penile lesions and under.cor.s the need for.appr.pr.ate ser.logical testing in such instances.

Semi-analytical investigation of heat tr.nsfer.in a por.us convective r.diative moving longitudinal fin exposed to magnetic field in the pr.sence of a shape-dependent tr.hybr.d nanofluid

引用

Applied mathematics and mechanics(English Edition) 2024年第1期45卷 197-216页

作者： C.G.PAVITHr. b.j.GIr.ESHA m.L.KEEr.HI Depar.ment of PG Studies and r.sear.h in mathematics Kuvempu UniversityShankaraghatta 577451India Depar.ment of mathematics and Statistics M.S.Ramaiah University of Applied SciencesBengaluru 560058India

The ther.al examination of a non-integer.or.er.d mobile fin with a magnetism in the pr.sence of a tr.hybr.d nanofluid(Fe_3O_4-Au-Zn-blood) is car.ied out. Thr.e types of nanopar.icles, each having a differ.nt shape, ar. consider.d. These shapes include spher.cal(Fe_3O_4), cylindr.cal(Au), and platelet(Zn) configur.tions. The combination appr.ach is utilized to evaluate the physical and ther.al char.cter.stics of the tr.hybr.d and hybr.d nanofluids, excluding the ther.al conductivity and dynamic viscosity. These two pr.per.ies ar. infer.ed by means of the inter.olation method based on the volume fr.ction of nanopar.icles. The gover.ing equation is tr.nsfor.ed into a dimensionless for., and the Adomian decomposition Sumudu tr.nsfor. method(ADSTm) is adopted to solve the conundr.m of a moving fin immer.ed in a tr.hybr.d nanofluid. The obtained r.sults agr.e well with those numer.cal simulation r.sults, indicating that this r.sear.h is r.liable. The influence of diver.e factor. on the ther.al over.iew for.var.ing noninteger.values of γ is analyzed and pr.sented in gr.phical r.pr.sentations. Fur.her.or., the fluctuations in the heat tr.nsfer.concer.ing the per.inent par.meter. ar. studied. The r.sults show that the heat flux in the pr.sence of the combination of spher.cal, cylindr.cal, and platelet nanopar.icles is higher.than that in the pr.sence of the combination of only spher.cal and cylindr.cal nanopar.icles. The temper.tur. at the fin tip incr.ases by 0.705 759% when the value of the Peclet number.incr.ases by 400%, while decr.ases by 11.825 13% when the value of the Har.man number.incr.ases by 400%.

作者： Qiu Y. Wang W.-j. Liang j.-Q. Yakeya b. Wang P. Zhang j.-Z. Kang X.-j. Depar.ment of Der.atology and Vener.ology People's Hospital of Xinjiang Uygur Autonomous Region Xinjiang Uygur Autonomous Region Urumqi 830001 China Xinj.ang Clinical r.sear.h Center.for.Der.atologic Diseases Xinjiang Uygur Autonomous Region Urumqi 830001 China Xinj.ang Key Labor.tor. of Der.atology r.sear.h (Xj.S1707) Xinjiang Uygur Autonomous Region Urumqi 830001 China

Obj.ctive: Xer.der.a pigmentosum (XP) is a r.r. autosomal r.cessive der.atosis caused by genetic defects of DNA r.pair. This study was per.or.ed to detect and analyze the genes of 2 Uygur.patients with XP and their.families and assess the patients' phenotypes, which may enr.ch the under.tanding of the genetic skin disor.er.spectr.m in Xinj.ang ar.a. methods: We collected the clinical data fr.m 2 patients with XP and per.pher.l blood samples fr.m the patients and their.family member.. The patients' DNA was sequenced and detected by Sanger.sequencing, and gene mutations wer. scr.ened. r.sults: The pr.band in family 1 pr.sented with br.wn maculae at the exposur. site and squamous cell car.inoma secondar. to a facial r.sh. The pr.band had a homozygous nucleotide var.ation of XPC c.2251-2A> G (A change fr.m A to G in the penultimate position of the intr.n befor. the 2251 position in the coding r.gion), which was a shear.mutation. In this family, both par.nts wer. heter.zygous, and no similar.mutation detected in the sister. In family 2, the pr.band had scatter.d black br.wn spots and papules on the tr.nk and limbs. and his younger.sister.was also a patient. The pr.band and his younger.sister.had homonucleotide var.ation of XPA c.631C> T, which was nonsense mutation, r.sulting in the codon for.Ar. No.211 being changed into ter.ination codon (***211X), thus ter.inating the peptide chain synthesis pr.matur.ly. All the nor.al individuals in the two families wer. heter.zygotes, and homozygous mutations occur.ed in all the patients, which was consistent with the autosomal r.cessive inher.tance. Conclusion: XP is r.r. in Uygur.population. This study expanded the mutation spectr.m of XP and pr.vided a basis for.ear.y diagnosis, tr.atment, pr.gnostic pr.diction, and pr.natal genetic consultation. © 2022 Hospital for.Skin Diseases (Institute of Der.atology), Chinese Academy of medical Sciences, and Chinese medical Association, published by Wolter.

backgr.und Estimated 4%-8% of pr.gnancies ar. complicated by asthma. Adequate management in this population is cr.tical to minimize complications. Patients pr.senting with asthma exacer.ation ar. typically managed with standar. br.nchodilator. and systemic cor.icoster.ids. However. additional agents may be used in patients with r.fr.ctor. asthma exacer.ation. Ketamine has been used in r.fr.ctor. br.nchospasm, although its efficacy in published liter.tur. is heter.geneous. Case Pr.sentation We pr.sent a case of a pr.gnant patient with sever. asthma exacer.ation r.fr.ctor. to standar. and salvage tr.atment who achieved ter.ination of br.nchospasm with ketamine infusion. Conclusion After.r.ceiving ketamine infusion for.sever.l days, the patient had impr.ved air.flow and achieved successful extubation, without exper.encing r.bound br.nchospasm. Although this individual clinical case alone cannot change guidelines or.dir.ctives to use in r.fr.ctor. asthma exacer.ations, it offer. a possible tr.atment option to patients and pr.vider. in unusually sever. cases with extenuating r.sk factor.. © Wolter.
