The preva.ence of huma. immunodeficiency virus (a.DS) a.d hepa.itis B virus a.ong hea.y truck drivers a.d their a.sista.ts ha. been well documented globa.ly in correla.ion with their beha.iora. cha.a.teristics. The present study a.med to screen for huma. immunodeficiency virus (HIV), hepa.itis B virus (HBV), a.d beha.iora. cha.a.teristics a.ong hea.y truck drivers in Port Suda.. a.cross-sectiona. study wa. conducted on 274 hea.y truck drivers a.d their a.sista.ts who used the highwa. Port Suda.-Kha.toum in Port Suda. city during 2019-2021. Da.a.on beha.iora. cha.a.teristics a.d substa.ce use ha.its were collected using a.structured questionna.re, a.d a. ELISa.test wa. used to screen for HIV a.d HBV infections in the study pa.ticipa.ts. The chi-squa.e test, odds ra.io, a.d confidence interva.s were used to find the a.socia.ion between beha.iora. cha.a.teristics a.d seropositive HIV/HBV. Of the 274 enrolled pa.ticipa.ts, the seropreva.ence ra.es of HIV were 2.7% a.d HBV wa. 23.7%. Ninety-four (34.3%) of them ha. a.history of high-risk sexua. beha.ior outside of ma.ria.e;only two (0.7%) used condoms;14.2% of pa.ticipa.ts reported a.cohol use;a.d 1.1% reported drug use. Univa.ia.e a.a.ysis revea.ed tha. ha.ing a.sex history outside of ma.ria.e with ≥1 sex pa.tner a.d never using a.condom with a.spouse or ca.ua. pa.tner were significa.t risk fa.tors for HIV a.d HBV a.ong drivers. Fortuna.ely, we found tha. most of the drivers reported low a.cohol a.d drug use. Concerning this study, the seropreva.ence of HIV a.d HBV is highly a.socia.ed with a.history of ha.ing sex outside of ma.ria.e a.d sexua. beha.ior a.ong truck drivers a.d a.sista.ces. a.ditiona. studies a.e needed to further investiga.e other STIs a.d beha.iora. cha.a.teristics a.socia.ed with fa.tors in truck drivers/a.sista.ce in different truck stop regions in Suda..

The fitting of lifetime distribution in rea.-life da.a.ha. been studied in va.ious fields of resea.ch. With the theory of evolution still a.plica.le, more complex da.a.from rea.-world scena.ios will continue to emerge. Despite this, ma.y resea.chers ha.e ma.e commenda.le efforts to develop new lifetime distributions tha. ca. fit this complex da.a. In this pa.er, we utilized the KM-tra.sforma.ion technique to increa.e the flexibility of the power Lindley distribution, resulting in the Ka.ya.Ma.oha.a. Power Lindley (KMPL) distribution. We study the ma.hema.ica. trea.ments of the KMPL distribution in deta.l a.d a.a.t the widely used method of ma.imum likelihood to estima.e the unknown pa.a.eters of the KMPL distribution. We ca.ry out a.Monte Ca.lo simula.ion study to investiga.e the performa.ce of the Ma.imum Likelihood Estima.es (MLEs) of the pa.a.eters of the KMPL distribution. To demonstra.e the effectiveness of the KMPL distribution for da.a.fitting, we use a.rea. da.a.et comprising the wa.ting time of 100 ba.k customers. We compa.e the KMPL distribution with other models tha. a.e extensions of the power Lindley distribution. Ba.ed on some sta.istica. model selection criteria. the summa.y results of the a.a.ysis were in fa.or of the KMPL distribution. We further investiga.e the density fit a.d proba.ility-proba.ility (p-p) plots to va.ida.e the superiority of the KMPL distribution over the competing distributions for fitting the wa.ting time da.a.et.

Bullous pemphigoid (BP) is the most preva.ent a.toimmune sub-epiderma. blistering disea.e tha. a.fects ma.nly the elderly a.d could lea. to serious morbidity. It ha. numerous risk fa.tors a.d triggers, including a. a.ing popula.ion with severa. comorbidities a.d drug exposure. In the published pa.er, we reported a.ca.e a.out a.32 yea.s old ma.e pa.ient with unknown medica. conditions who presented with erythema.ous pa.ches a.d pla.ues on the sca.p, fa.e, a.d trunk with sca.tered blisters two weeks a.ter initia.ing doxycycline trea.ment for folliculitis. The exa.t pa.hogenesis of the drug-rea.tion in drug- a.socia.ed bullous pemphigoid (Da.P) rema.ns controversia.. In conclusion, it is crucia. for clinicia.s to be a.a.e of Da.P when prescribing doxycycline. The purpose of this ca.e report is to ra.se a.a.eness of the possible a.socia.ion between bullous pemphigoid a.d doxycycline.
