Background: Basal cell carcinoma (BCC) occurs frequently in young patients with xeroderma pigmentosum (XP). Because tumours are multiple and usually found on the face, alternatives to surgery are proposed. The purpose of this study was to evaluate the efficacy of cryosurgery for BCC in XP patients.
Patients And Methods: This was a retrospective study that included all instances of BCC occurring in XP patients treated by cryosurgery between January 2002 and October 2008.
Results: Forty-five cases of primary facial BCC and one case of relapsing BCC (16 on the cheeks, 11 on the nose, six on the face and five on the inner edge of the eye area) were treated by cryosurgery in 18 XP patients (average age: 18.7 years; sex ratio: 0.5). Mean carcinoma size was 10mm. Thirty-six tumours were nodular and 10 were nodular and ulcerated. Follow-up ranged from 16 to 60 months (mean: 30 months). Complications were rare. Cosmetic results were satisfactory. We noted 10 cases of hypopigmentation (21.7%) and one notch on the nose following treatment for recurrent BCC on a radiotherapy scar. Relapse occurred in one case (2.17%).
Conclusion: Because of its simplicity, its good safety, its sparing of skin and its reliability of oncological outcome, cryosurgery is the treatment of choice for CBC in XP patients.

Patient engagement and shared decision-making (SDM) between patients and clinicians is the foundation of patient-centered care. It aims to reach a treatment option that fits the patient's preference and is guideline-concordant. We sought to evaluate the possible causes and outcomes of patient's non-guideline-concordant care choices.

Pulmonary vein isolation (PVI) with cryoballoon (CB) ablation technology is widely used to treat drug-resistant atrial fibrillation (AF). During CB ablation, there is a possibility of forming an ice cap of contrast-color on top of the balloon. If automatic balloon deflate occurs before the ice cap dissolves, embolization to the systemic circulation is possible.

Both the surgical non-cultured melanocyte-keratinocyte transplant procedure (MKTP) and intradermal injection of 5-Fluorouracil (5-FU) are effective in the treatment of vitiligo. Intrablisters injection of MKTP was done in one study with better results than MKTP application after ablative CO2 laser of the reciepient area. However, intrablister injection of 5-FU was not done before.

Background: Neuroimmune interaction is an underestimated mechanism for lung diseases, and cryoablation is a competitive advantageous technique than other non-pharmacologic interventions for peripheral nerve innervating the lung. However, a lack of cryodenervation model in laboratory rodents leads to the obscure mechanisms for techniques used in clinic.
Method: Herein, we developed a novel practical method for mouse peripheral nerve cryoablation, named visualized and simple cryodenervation (VSCD).

Background: Cryoablation induces antitumor immune responses. Spatial transcriptomic landscape technology has been used to determine the micron-level panoramic transcriptomics of tissue slices in situ.
Methods: The effects of cryoablation on the immune microenvironment in non-small cell lung cancer (NSCLC) were explored by comparing the Whole Transcriptome Atlas (WTA) panel of immune cells before and after cryoablation using the spatial transcriptomic landscape.
