erein, the experiments were performed only in isolated cavernous tissue (in vitro), thus the lack of knowledge on how the TLR9 modulates the in vivo response of the erectile tissue is another limitation of this study.

Our findings indicate that CC dysfunction observed in obesity is at least in part mediated by the production of TNF-α upon activation of TLR9 expressed in the macrophages.

Metoidioplasty is a possibility for penis reconstruction in transmen that could be enhanced by a semi-rigid prosthesis support.

Describe the surgical technique of metoidioplasty with implantation of a specifically designed semi-rigid prosthesis -the ZSI100D4- and analyze preliminary results.

Implantation of semi-rigid prosthesis was proposed to transmen who chose metoidioplasty for genital gender affirming surgery in a specialized university hospital.

Surgical outcomes were collected from medical files. Functional outcomes and satisfaction were collected post-operatively with a questionnaire.

A total of 15 patients were operated; the mean length of followup was 22 months (SD = 8.7). Median prosthesis size was 8.5 cm (range 8.5-10). Seven (46.7%) minor complications (Clavien-Dindo grade 2; 5 wound dehiscence and 2 fistula, managed conservatively) and 1 severe (Clavien-Dindo grade 3b) complication (Hematoma that need surgical revision) occurred. Thirteen patients (86.6%) answered the questionnaire; 11 (84.6%) reported being either "very satisfied" or "satisfied" with the appearance of the new genitalia; 10 (76.9%) could void while standing; and 12 patients (92.3%) answered "not at all" to the question "do you have regrets about this surgery ?".

Implantation of a semi-rigid prosthesis in an enlarged clitoris seems to be a valuable option and can be proposed as another possibility for the complex surgical answer to neophallus reconstruction in transmen.

Ionizing radiation exposure in catheter ablation procedures carries health risks, especially in pediatric patients. Our aim was to compare the safety and efficacy of catheter ablation guided by a nonfluoroscopic intracardiac navigation system (NFINS) with those of an exclusively fluoroscopy-guided approach in pediatric patients.

We analyzed catheter ablation results in pediatric patients with high-risk accessory pathways or supraventricular tachycardia referred to our center during a 6-year period. We compared fluoroscopy-guided procedures (group A) with NFINS guided procedures (group B).

We analyzed 120 catheter ablation procedures in 110 pediatric patients (11±3.2 years, 70% male); there were 62 procedures in group A and 58 in group B. We found no significant differences between the 2 groups in procedure success (95% group A vs 93.5% group B; P=.53), complications (1.7% vs 1.6%; P=.23), or recurrences (7.3% vs 6.9%; P = .61). However, fluoroscopy time (median 1.1minutes vs 12minutes; P<.0005) and ablation time (median 96.5seconds vs 133.5seconds; P=.03) were lower in group B. The presence of structural heart disease was independently associated with recurrence (P=.03).

The use of NFINS to guide catheter ablation procedures in pediatric patients reduces radiation exposure time. Its widespread use in pediatric ablations could decrease the risk of ionizing radiation.

The objective of this study was to estimate the possible number of cancer cases produced during 2019 in US dental offices from radiography, estimate the possible reduction in those rates resulting from use of intraoral rectangular collimation and selection criteria, and determine the frequency and quality of website radiation risk information and informed consent forms.

An analysis of dental radiation examinations in 2014 to 2015 US national survey data, Nationwide Evaluation of X-ray Trends, and National Council on Radiation Protection and Measurements surveys was performed, in addition to an analysis of 2008 to 2020 Journal of Clinical Orthodontics national orthodontic surveys for radiographic examination frequencies. Thiostrepton clinical trial Lifetime attributable cancer risk estimates from US and European studies were used to generate the total dental and orthodontic office cancer totals. In total, 150 offices were examined online for the quality and frequency of risk information in websites and consent forms.

The 2019 estimate for all office cancers is 967. Collimation and selection criteria could reduce this to 237 cancer cases. Most cancers arise from intraoral and cone beam computed tomography examinations, with 135 orthodontic cancers over 21 months (average treatment time). Collimation and selection criteria could reduce this to 68. Only 1% of offices use collimators or informed consent for radiography. The website and consent information were of poor quality.

Dentists are not following selection criteria or using collimators according to guidelines. Up to 75% of cancer cases could be avoided.
