TRPV1 mediates itch‐associated scratching and skin barrier dysfunction in DNFB‐induced atopic dermatitis mice

xlomafota13 shared this article with you from Inoreader

Abstract

In chronic pruritic diseases such as atopic dermatitis (AD), pruritus and skin lesions is exacerbated by scratching in clinical and experimental settings. TRPV1 is known to mediate itch and neurogenic inflammation, but the role of TRPV1 in itch-associated scratching in AD is poorly understood. In this study, we examined the efficacy of cutting off nails and TRPV1 antagonist, ruthenium red (RR) in a murine model of AD induced by DNFB and further investigated the underlying mechanism. Nail clipping or RR could markedly ameliorate the general AD-like symptoms as manifested by the reduced clinical severity of dermatitis, IgE and Th2-related cytokine levels, and mast cell degranulation. Moreover, scratching behavior, the levels of pruritogenic mediators, including HIS, TSLP, IL-31 and SP, and skin pH and TEWL were all significantly decreased in nail clipping or RR-treated mice, suggesting a reduction in itch-associated scratching and skin barrier defects. Immunofluorescence staini ng and western blot results revealed that that antipruritic effect of nail clipping or RR in AD may be explained, at least in part, by the suppression of TRPV1 activation. In summary, these data show that TRPV1 mediates itch-associated scratching and subsequent skin barrier defects, suggesting its potential as a therapeutic target in AD.

A systematic review and meta-analysis of urethral complications and outcomes in transgender men

xlomafota13 shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2021 Sep 4:S1748-6815(21)00384-3. doi: 10.1016/j.bjps.2021.08.006. Online ahead of print.

ABSTRACT

BACKGROUND: Urologic problems, such as urethral fistulas and strictures, are among the most frequent complications occurring after phalloplasty. Although many studies have reported successful phalloplasty and urethral reconstruction with reliable outcomes in transgender men, no method has become standardized so far. This study aimed to summarize the results of reports on urological complications and outcomes in transgender men with respect to various types of urethral reconstruction.

METHODS: A comprehensive literature search of PubMed, Scopus, and Google Scholar databases was conducted for studies related to phalloplasty in transsexuals. Data on various phallic urethral techniques, urethral complications, and outcomes were collected and analyzed using the random-effects model.

RESULTS: A total o f 21 studies (1,566 patients) were included: eight studies (1,061 patients) on "tube-in-tube," nine studies (273 patients) on "prelaminated flap," and six studies (221 patients) on "second flap." Compared with the tube-in-tube technique, the prelaminated flap was associated with a significantly higher urethral stricture/stenosis rate; however, there was no difference between the prelaminated flap and the second flap techniques. For all phalloplasty patients, the pool rate of urethral fistula or stenosis is 48.9%, the rate of the ability to void while standing is 91.5%, occurrence rate of tactile or erogenous sensation is 88%, the prosthesis complication rate is 27.9%, and patient-reported satisfactory outcome rate is 90.5%.

CONCLUSION: Urethral reconstruction with a prelaminated flap was associated with a significantly higher urethral stricture rate and increased need of revision surgery compared with that observed using a skin flap. Overall, most patients were able to void wh ile standing and were satisfied with the outcomes.

KTP laser endoscopic cricopharyngeal myotomy and pharyngeal pouch diverticulotomy: how I do it

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2021 Oct 5. doi: 10.1007/s00405-021-07101-z. Online ahead of print.

ABSTRACT

BACKGROUND: Various endoscopic methods of dividing the cricopharyngeus muscle and the common wall of pharyngeal pouches have been described, most commonly the carbon dioxide laser and stapler. The potassium titanyl phosphate (KTP) laser is an alternate endoscopic method of treatment.

METHODS: The KTP laser is used in a similar fashion to the carbon dioxide laser to carefully divide the cricopharyngeus muscle fibres ± the common wall of the pharyngeal pouch, under microscopic visualization.

CONCLUSION: The KTP laser is an alternative and safe technique for these surgeries.
