RESUMEN

Objectives: This study aimed to evaluate the vagina clinically, cytologically, and histologically before and after treating genitourinary syndrome of menopause (GSM) with fractional microablative carbon dioxide LASER (CO2L), radiofrequency (RF), and estrogen vaginal cream (CT). Methods: Women with moderate-to-severe symptoms of GSM, denoted by a GSM Visual analog scale (VAS) score of >4, were eligible for this study. The patients were randomized into treatment groups. In the energy groups, three vulvovaginal applications were administered monthly. The CT group used 0.5 mg vaginal estriol cream for 14 consecutive days, followed by twice a week for 4 months. The follow-up visits occurred 120 days after the beginning of the treatments. The same parameters obtained at the first visit were re-evaluated: GSM VAS score, Incontinence Quality of Life Questionnaire (I-QOL), gynecological examination determining Vaginal Health Index (VHI), vaginal smear for Vaginal Maturation Value (VMV), and vaginal biopsy. Results: Seventy-one women were included, 48 completed the study and provided adequate samples for analysis (CO2L [21 patients], RF [15 patients], and CT [12 patients]). GSM symptoms, I-QOL, and VHI significantly improved after all proposed treatments, with no significant differences between them. VMV did not change after any treatment; however, only 22.9% of the patients presented with cytological atrophy before treatment. Histological vaginal atrophy was identified in 6 (12.5%) pretreated vaginal samples. After the intervention, all histological parameters were normalized, no tissue damage was observed, and no major clinical complications were observed. Conclusion: CO2L and RF seem to be good alternatives to CT for GSM treatment, with no tissue damage.

RESUMEN

Introduction: Chronic tonsillitis has a global prevalence, ranging from 5% to 12%. Its clinical manifestations, like recurrent acute tonsillitis, tonsils hypertrophy, caseum and halitosis, can lead adult patients to be submitted to palatine tonsillectomy, surgery that has morbidity and the potential risk of complications, including severe bleeding. This article proposes a new therapy for chronic tonsillitis in adult patients using a fractional carbon dioxide (CO2) laser, which is a fast, minimally invasive procedure capable of removing the need for the traditional tonsillectomy in many patients. The present research aimed to verify the efficacy of tonsillotomy by fractional ablation using the CO2 laser by comparing the number of bacterial infections, tonsils hypertrophy, halitosis and caseum; it is also aimed at analyzing the benefits, risks and complications of the technique. Methods: In this clinical prospective study, 20 patients were subjected to one session of tonsillotomy by fractional ablation and were followed up for a year. The control group was formed by the same patients in the pre-procedure period (one year) without treatment. Statistical analysis: The Wilcoxon paired test, Friedman tests, and multiple non-parametric comparisons were utilized to analyze the data (significance level of 5%). Results: No complications occurred, and the procedure was fast (30 seconds), safe and tolerated well without general anesthesia. After 1 year, there was a total remission of recurrent acute tonsillitis in 95% of the patients, and after 6 months there was a statistically significant improvement in halitosis and caseum, and tonsils size reduction (P<0.05). The level of satisfaction average was 10 after 3 months and 8 after one year. Conclusion: tonsillotomy by fractional ablation using the CO2 laser is a safe, efficient procedure for chronic tonsillitis in adults, and it can be incorporated into daily clinical practice.

RESUMEN

OBJECTIVE: The aim of the study was to evaluate the clinical response and collagen remodeling in the vaginal wall after three sessions of carbon dioxide (CO2) laser application. METHODS: Fourteen postmenopausal women with vulvovaginal atrophy, aged 45-65 years and sexually active, were evaluated with clinical questionnaires, gynecological examinations and histological techniques before and after 20 weeks of treatment (ClinicalTrials.gov NCT03939078). Treatment consisted of 3-monthly sessions of the CO2 laser. Clinical questionnaires included the Vaginal Health Index, the Female Sexual Function Index and the International Consultation on Incontinence Questionnaires Short Form. Biopsies were taken from the lateral vaginal wall at week 0 (left wall) and week 20 (right wall). Tissue samples were stained with hematoxylin and eosin, Periodic Acid-Schiff, Picrosirius Red Stain and Orcein dyes. Immunohistochemical study was used to quantify collagens I and III in the samples. RESULTS: The mean age was 54.4 ± 4.5 years, and the average time of amenorrhea was 7.6 ± 5.1 years. The Female Sexual Function Index and the Vaginal Health Index Score values increased while the International Consultation on Incontinence Questionnaire Short Form score decreased after the programmed treatment. There was no significant change in vaginal pH. Histological studies showed increases in the total and superficial epithelial cell layers, and type III collagen fibers (from 10.86 ± 7.66 to 16.87 ± 3.96, p < 0.05), and immunohistochemical studies confirmed the significant increase in collagen III. CONCLUSION: Histological findings revealed epithelial atrophy reversal and collagen remodeling of the vaginal wall. Immunohistochemical analysis showed an increase in collagen type III fibers.

RESUMEN

Abstract Introduction Schwannomas are benign, solitary, encapsulated tumors that may originate at any site of the peripheral nervous system, with the exception of the olfactory and optic nerves. Schwannomas of the base of tongue are very rare, and only sporadic cases are documented. The tongue base represents a challenge for surgeons. Carbon dioxide (CO2) laser might provide an effective surgical option for such lesions because of the easy access to the lesion, the bloodless surgical field and optimum epithelization of wounds. Objective We present an unusual case of pedunculated schwannoma of the tongue base treated via transoral CO2-assisted excision. We also provide a review of the available literature, in English language, on humans. Data synthesis The authors searched the PubMed database and Google up to July 2018. The following search terms were applied: tongue and lingual, combined with schwannoma and neurilemmoma. Titles and abstracts were screened, and, then, only supraglottic (hypopharyngeal) tongue base masses were considered. Fourteen articles were included in this review, reporting 17 cases. The age of the patients ranged from 9 to 39 years, affecting predominantly females. Dysphagia and lump sensations were the most common presenting symptoms, and the mean follow-up period range was 1.5 to 60 months (mean = 13 months). There was no evidence of recurrence in any of the cases. Conclusion We could conclude that tongue base schwannomas are rare. Transoral complete excision of the tumor is the treatment of choice. CO2 laser surgery is a minimally invasive treatment option that has been performed in few reports with no recurrence and with favorable outcomes.

RESUMEN

BACKGROUND: Basal cell carcinoma (BCC) treatment modalities can be stratified by tumor subtype and recurrence risk. The main limitation of nonsurgical treatment modalities is the lack of histopathologic confirmation. Reflectance confocal microscopy (RCM) is a noninvasive imaging device that provides quasihistologic images. OBJECTIVE: To evaluate the feasibility and efficacy of RCM-guided carbon dioxide (CO2) laser ablation of low-risk BCCs. METHODS: Prospective study with biopsy specimen-proven low-risk BCCs imaged with RCM. RCM was performed on these sites before and after ablation. If residual tumor was found, a new series of laser passes were performed. The patients were then monitored for recurrence clinically and with RCM. RESULTS: Twenty-two tumor sites in 9 patients (5 men, 4 women) were imaged and treated. Median age was 59 ± 12.9 years (range, 30-74 years). Mean tumor size was 7.7 mm (range, 5-10 mm). Residual tumor was identified in 5 of 22 cases (22.7%) under RCM on immediate first-pass postablation sites, prompting additional laser passes. Median follow-up was 28.5 months (range, 22-32 months) with no recurrences found. CONCLUSIONS: Addition of RCM to laser ablation workflow can detect subclinical persistent tumor after initial ablation and may serve as an aid to increase the efficacy of laser ablation.
