Effect of Broccoli Sprout Extract on Keratinocyte Differentiation in Normal Skin
Epidermolysis Bullosa SimplexPachyonychia CongenitaAdult participants will apply a broccoli sprout extract-jojoba oil compound to one arm every night under occlusion for 1 week. Jojoba oil alone will be applied to the other arm. At the end of 1 week, a 6mm punch biopsy will be taken from both arms and analyzed via polymerase chain reaction (PCR) and immunohistochemistry for differences in various skin proteins.
Pilot Study of Efficacy of Nail Gel in Finger Nail Surface Abnormality
Nail AbnormalitiesNail surface abnormalities is any conditions that affect the nail matrix or nail bed which cause nail plates grow defectively. Common nail surface abnormalities are pitting nails, longitudinal ridging, and transverse ridging/Beau's line. Aging nails usually have nail surface abnormalities as well. Nail gels are artificial nails used widely for aesthetic purposes. Although, their cosmetic use is increasing with day by day, their usefulness in conditions such as nail biting, brittle nails, and ingrown toe nails has been reported. Moreover, a previous study reported the benefits of nail gels in terms of improving nail surface abnormalities like pitting nails, trachyonychia, and onychoschizia. This study was conducted to evaluate the efficacy of nail gel containing Glycerin which has humectant effect and Artemisia Abrotanum extract which has anti-fungal/bacterial activities in finger nail surface abnormalities.
Phase 2/3 Study Evaluating the Safety and Efficacy of PTX-022 in Treatment of Adults With Pachyonychia...
Pachyonychia CongenitaThis study evaluates the safety and efficacy of PTX-022, topical rapamycin, in the treatment of adults with moderate to severe Pachyonychia Congenita. This study includes four-parts, and if a participant completes all parts, the participant will have received at least 3-months of PTX-022 treatment.
Simvastatin Treatment of Pachyonychia Congenita
Pachyonychia CongenitaSimvastatin and related statins, such as compactin, are able to inhibit the constitutive expression of inducible/repressible keratin genes such as K6a and K17. This effect is due to the reported ability of statins to inhibit STAT1 expression (Lee et al., 2007). The constitutive K6a promoter activity is dependent on STAT1 and blocked by simvastatin or siRNA against STAT1. This STAT1-dependent constitutive expression of K6a, is independent of JAK (Janus family of kinases). Thus simvastatin is capable of down-regulating both the constitutive and interferon-inducible expression of PC-related keratins such as K6a and K17. Therefore, this class of molecule has potential for the treatment of PC or related inherited disorders where the causative mutation resides in an inducible/repressible keratin gene such as K6a or K17. Simvastatin or other statins approved for human use might be delivered either orally, as is currently the case for cholesterol-lowering treatment or, if higher therapeutic doses are required in skin for reduction of hyperkeratosis in PC or in related keratinizing disorders, this might be achieved by topical formulations.
Botulinumtoxin A Treatment in Epidermolysis Bullosa Simplex and Pachyonychia Congenita
Epidermolysis Bullosa SimplexThis study evaluates the clinical effect of foot injection of the bacteria protein Botulinum toxin A on plantar pain in patients with EBS (epidermolysis bullosa simplex) or PC (pachyonychia congenita).
Effects of Isotretinoin on the Growth Rate and Thickness of the Nail Plate
IsotretinoinNail AbnormalityThe nail is an important skin appendage which can provide information about the person's overall health status in addition to having several important functions such as protection, tactile sensation, grasping. Many nail abnormalities which can have considerable psychological impact are side effects of drug administration. Retinoids have various effects on nails. Although isotretinoin as a retinoid has been associated with both decreased and increased nail growth, the great majority of such associations are not evidence-based. So, it was aimed to investigate the effects of isotretinoin on morphology, growth rate, and thickness of the nail plate.
