RESUMO

Las pápulas perladas del pene son angiofibromas acrales, lesiones asintomáticas benignas, no infecciosas, ubicadas alrededor del glande masculino. Debido su aspecto suelen causar angustia, disminución de autoestima y dificultades en la intimidad sexual. Todo esto lleva a un deterioro de la calidad de vida sexual. Métodos. Se incluyeron pacientes varones con pápulas perladas peneanas que recibieron tratamiento con láser de dióxido de carbono fraccionado entre diciembre de 2023 y abril de 2014. Se trataron en total 75 pacientes. Previo al tratamiento se les realizó una encuesta para saber si había realizado consulta previa con especialista y los motivos para realizar el tratamiento. Se les realizó el primer control postratamiento entre 10 a 15 días post tratamiento. En caso de presentar pápulas perladas peneanas residuales se procedió a un segundo o tercer tratamiento. Se les realizó segundo y tercer control postratamiento entre 10 a 15 días postratamiento. En dicho segundo o tercer control se les realizó encuesta de satisfacción. Resultados. Todos los pacientes incluidos en nuestro estudio informaron que se lograron eliminar sus pápulas perladas peneanas: 13% (10 pacientes) en primera sesión, 82% (62 pacientes) en segunda sesión y solo 4% (3 pacientes) requirieron una tercera sesión. Conclusiones. Las pápulas perladas peneanas, aun siendo de etiología benigna y no contagiosa, reducen significativamente la calidad de vida sexual de los varones, especialmente los jóvenes, y merecen de un tratamiento médico. El tratamiento de las pápulas perladas peneanas mediante uso de láser de dióxido de carbono fraccionado demostró ser un tratamiento rápido, seguro y eficaz

Pearly penile papules are acral angiofi bromas, benign, non-infectious, asymptomatic lesions around the male glans. Due to their appearance, they often cause distress, decreased self-esteem, and difficulties in sexual intimacy. All this leads to a deterioration in the quality of sexual life. Methods. Male patients with pearly penile papules who received fractionated carbon dioxide laser treatment between December 2023 and April 2014 were included. A total of 75 patients were treated. Before the treatment, a survey was conducted to fi nd out if they had previously consulted with a specialist and what motivated them to undergo the treatment. They underwent their first post-treatment control between 10 to 15 days after treatment. If residual pearly penile papules were present, a second or third treatment was performed. A second and third post-treatment control was carried out between 10 to 15 days after treatment. In said second or third control, a satisfaction survey was carried out. Results. All patients included in our study reported that their pearly penile papules were eliminated: 13% (10 patients) in the fi rst session, 82% (62 patients) in the second session, and only 4% (3 patients) required a third session. Conclusions. Pearly penile papules, even though they are of benign and non-contagious etiology. They signifi cantly reduce the quality of sexual life of men, especially young men, and deserve medical treatment. The treatment of pearly penile papules using fractionated carbon dioxide laser proved to be fast, safe, and effective.

RESUMO

PURPOSE: Tumors affecting the female genital tract and their treatments have the potential to induce adverse modifications in vaginal health and impact personal aspects of patient's lives. Vulvovaginal atrophy is one of the morphological changes observed in individuals with a history of gynecological cancer, influenced both by the biological environment of tumors and the main therapeutic modalities employed. Therefore, the purpose of this study was to identify approaches to treat vulvovaginal atrophy while assessing the impact on the emotional and sexual health of women diagnosed with gynecological cancers. METHODS: To achieve this goal, a systematic review was conducted following the methodological guidelines outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The databases used for literature research were PubMed and Web of Science. RESULTS: Initially, 886 articles were obtained. After eliminating duplicates and applying inclusion/exclusion criteria, seven articles were selected for analysis. The period of highest publication activity spanned from 2017 to 2020, with the majority conducted in Italy. Five treatment modalities were identified and categorized as vaginal suppository, oral medication, surgical procedure, CO2 laser therapy, and vaginal dilator. Twenty-four outcomes related to vaginal health and 30 outcomes related to overall, sexual, and emotional quality of life were analyzed. CONCLUSION: In general, all interventions demonstrated the ability to improve vaginal health or, at the very least, the sexual health of patients. Thus, despite limitations, all treatments have the potential to address vulvovaginal atrophy in patients with a history of gynecological cancer.

RESUMO

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.

RESUMO

El síndrome genitourinario es una entidad hoy en día cada vez más frecuente en la mujer posmenopáusica, con signos y síntomas muy característicos que llevan a la pérdida de calidad de vida de las pacientes, generados por la disminución de estrógenos. Su diagnóstico se realiza mediante una buena historia clínica, exámenes hormonales, estudios urodinámicos y de pH vaginal. Su clínica varía desde sequedad vaginal, atrofia de la misma, vaginitis a repetición, pérdida de orina al esfuerzo, nicturia y dispareunia. A los largo de los años se han protocolizado diferentes tratamientos como reemplazos hormonales, lubricantes y cirugías invasivas vaginales. Pero en los últimos años ha aparecido una nueva terapéutica de láser CO2 fraccionado. Materiales y método. Se realizó un estudio retrospectivo de seis años de evolución, entre los años 2017 y 2023, con más de 300 pacientes tratadas con tecnología láser CO2 fraccionado, con criterios de inclusión y exclusión, protocolizando 3 sesiones cada 30 días y controles hasta los 6 meses. Resultados. Para evaluar los resultados se diseñó una encuentra de satisfacción de 5 puntos, la cual fue presentada luego de cada sesión, encontrando un alto grado de satisfacción en la mejoría clínica a medida que transcurrían las sesiones, con un muy bajo índice de complicaciones. También biopsias con mejorías histológicas que demuestran resultados. Discusión. La aplicación de esta nueva tecnología láser nos abre una posibilidad terapéutica segura, rápida y efectiva para mejorar la sintomatología y calidad de vida de nuestras pacientes con síndrome genitourinario, sumando una nueva terapéutica a todo el arsenal de tratamientos médico-quirúrgicos disponibles a la fecha. Conclusiones. El síndrome genitourinario es una entidad prácticamente inevitable, con síntomas desde leves a graves, que afecta la calidad de vida personal, sexual y social. Los tratamientos hasta la fecha hormonales, tópicos o quirúrgicos han dado mediocres resultados sin estar exentos de complicaciones, por lo que la aparición de la tecnología láser CO2 fraccionada nos ha dado el plus necesario para aportar un tratamiento seguro, eficaz, con mínimas complicaciones y una curva de aprendizaje pequeña

Genitourinary syndrome is an increasingly frequent entity in postmenopausal women today, with very characteristic signs and symptoms that lead to a loss of quality of life in patients, generated by estrogen depletion, whose diagnosis is made through a good clinical history, hormonal tests, urodynamic and vaginal pH studies. Its symptoms vary from vaginal dryness, vaginal atrophy, repeated vaginitis, loss of urine on exertion, nocturia and dyspareunia. Over the years, different treatments have been protocolized, such as hormone replacements, lubricants, and invasive vaginal surgeries. But in recent years a new fractionated CO2 laser therapy has appeared. Materials and method. A retrospective study of six years of evolution was carried out, between the years 2017 and 2023, with more than 300 patients treated with fractionated CO2 laser technology, with inclusion and exclusion criteria, protocolizing 3 sessions every 30 days and controls until the 6 months. Results. To evaluate the results, a 5-point satisfaction score was designed, which was presented after each session, finding a high degree of satisfaction in the clinical improvement as the sessions progressed with a very low indication of complications. Also biopsies with histological improvements that demonstrate results. Discussion. The application of this new laser technology opens up a safe, fast and effective therapeutic possibility to improve the symptoms and quality of life of our patients with genitourinary syndrome, adding a new therapeutic option to the arsenal of medical-surgical treatments available to date. Conclusions. Genitourinary syndrome is a practically inevitable entity, with symptoms ranging from mild to severe, affecting the quality of personal, sexual and social life. The hormonal, topical or surgical treatments to date have given mediocre results, not being free of complications, so the appearance of fractionated CO2 laser technology has given us the necessary extra to provide a safe, effective treatment, with minimal complications. and a small learning curve.

RESUMO

Objective: This pilot study intended to assess the feasibility of a large-scale randomized clinical trial designed to analyze the effectiveness of microablative fractional CO2 laser (CO2L) and microablative fractional radiofrequency (RF) compared with vaginal estriol (VE) as treatments for women with moderate-to-severe Genitourinary Syndrome of Menopause (GSM). Methods: Participants were randomized into VE, CO2L, or RF groups. In the VE group, women were required to use vaginal estriol cream for 14 days and then twice a week for 4 months. In the CO2L and RF groups, three energy therapies were administered at monthly intervals. Visual Analog Scale (VAS) for GSM symptoms, Female Sexual Function Index (FSF-I), Vaginal Health Index (VHI), and Nugent Score (NS) were analyzed before and 120 days after the beginning of the treatments. Pain scores were verified after each CO2L and RF session. Results: Thirty-four participants completed the study: 11 in the VE group, 11 in the CO2L group, and 12 in the RF group. No unexpected or serious adverse events were observed. We also verified that GSM symptoms, sexual function, and VHI significantly improved (p < 0.05) with no difference among the groups. NS did not show statistically significant difference before and after the treatments. Pain during RF application was associated with higher scores. Conclusions: The study is feasible and does not seem to have safety implications. Preliminary results suggest that CO2L and RF are good alternatives to VE for ameliorating clinical symptoms, FSF-I, and VHI in patients with GSM. Clinical Trial Registration number: NCT04045379.

RESUMO

OBJECTIVE: This study aimed to compare the efficacy of CO 2 laser, radiofrequency, and promestriene in treating genitourinary syndrome of menopause in women with breast cancer receiving adjuvant therapy and to analyze the clinical and histological findings of the vulvar vestibule. METHODS: Women with moderate-to-severe symptoms of vulvar atrophy were enrolled. The participants were evaluated according to pretreatment and posttreatment protocols using the visual analog scale and clinical assessments, which included a gynecological examination and vestibular biopsy. Participants were randomly assigned into the laser, radiofrequency, or promestriene groups. Participants in the energy treatment groups underwent three consecutive monthly outpatient vulvovaginal treatment sessions, whereas those in the control group were administered promestriene for 4 months. During a follow-up visit 30 days posttreatment, the participant global posttreatment impression of improvement was evaluated using a Likert scale. RESULTS: Seventy women completed treatment. Histological vulvar atrophy was identified in four (5.7%) of the pretreatment vulvar samples. Postintervention, all histological parameters were normalized. Significant improvements in symptoms were observed, as all three groups showed a reduction in the visual analog scale score, with no statistically significant differences among them. A high level of satisfaction was reported posttreatment in all groups. No damage to the histological structure of the vulvar vestibule or relevant clinical adverse events were identified posttreatment. CONCLUSIONS: Laser, radiofrequency, and promestriene delivered comparable, significant symptom improvements among women with breast cancer receiving adjuvant therapy. These treatments did not cause structural tissue damage or other clinical complications.

RESUMO

OBJECTIVE: This in situ study aimed to investigate the efficacy of CO2 laser at a 10.6-µm wavelength combined with 1.23% acidulated phosphate fluoride (APF) and fluoridated dentifrice with 1100 µg F/g (FD) to control enamel caries progression. MATERIALS AND METHODS: Sixteen volunteers wore palatal appliances containing eight demineralized enamel specimens for four 14-day phases under sucrose exposure. These specimens were submitted to CO2 laser irradiation and APF alone or combined with FD. Treatment groups were non-fluoridated dentifrice-NFD, NFD + CO2 laser, NFD + APF, NFD + CO2 laser + APF, FD, FD + CO2 laser, FD + APF, and FD + CO2 laser + APF. Mineral loss, calcium fluoride (CaF2), fluorapatite (FAp), and fluoride in the biofilm were analyzed by analysis of variance followed by the Student-Newman-Keuls test, p < 0.05. RESULTS: The highest mineral loss inhibition was noted when FD and CO2 laser irradiation were combined, which did not significantly differ from the FD + CO2 laser + APF group. The CaF2, FAp, and F in the biofilm were more pronounced when the FD and APF were combined. The CO2 laser irradiation promoted a slightly higher concentration of CaF2 in the enamel and F in the biofilm. CONCLUSION: Although APF promotes the high formation of CaF2 and FAp, the combined use of FD with CO2 laser overcomes the APF effect in inhibiting the progression of artificial caries-like lesions in situ. CLINICAL SIGNIFICANCE: Under the in situ design of this study, remineralization of white spot lesions was achieved through CO2 laser irradiation and daily use of fluoridated dentifrice. Future clinical trials are encouraged to substantiate this finding.

RESUMO

OBJECTIVES: The main objective of the study was to describe and compare the feasibility of using fractional CO2 laser to the usual treatment with Clobetasol. Randomized clinical trials brought together 20 women from a Brazilian university hospital, 9 of them were submitted to Clobetasol treatment and 11 to laser therapy. Sociodemographic data were obtained and quality of life parameters, vulvar anatomy, self-perception and histopathological analysis of vulvar biopsies were evaluated. Evaluations were made before the beginning of the treatment, during its implementation, right after its completion (3 months), and 12 months after. The SPSS 14.0 software was used, obtaining descriptive measurements. The level of significance adopted was 5%. RESULTS: The clinical/anatomical characteristics of the vulva did not differ between the treatment groups, as much before as after its performance. There was no statistically significant difference between the treatments performed regarding the impact on the life quality of the patients. A higher satisfaction degree with the treatment was obtained with the patients in the Laser group in the third month of evaluation. Laser therapy also revealed higher occurrence of telangiectasia after treatment completion. Fractional CO2 laser has proven to be well accepted and is a promising therapeutic option. Registration number and name of trial registry The institutional review board status was approved by the Research Ethics Committee of HU/ UFJF under advisory number 2881073 and registered in the Brazilian Clinical Trials, with consent under registration RBR-4p9s5y.

RESUMO

This in vitro study evaluated the potential of CO2 laser (10.6 µm) combined with a stannous/fluoride-containing solution for preventing erosion in human/bovine enamel. Forty-eight samples of each substrate were randomly allocated to four groups (n = 12): W - distilled water; E - AmF/NaF/SnCl2 solution; L - CO2 laser; and LE - CO2 laser+AmF/NaF/SnCl2 solution. After surface treatments, samples were submitted to a 5-day erosive challenge, alternating immersions in 0.5% citric acid (2 minutes, 6x/day) and in artificial saliva. Optical profilometry (µm) and scanning electron microscopy (SEM) were used to determine surface loss and surface morphology, respectively. Data were statistically analyzed by two-way ANOVA and Tukey's tests (p < 0.05). For human enamel, tissue loss was lower in group L (12.37 ± 4.46) than in group W (16.45 ± 2.76), and higher than in the groups treated with AmF/NaF/SnCl2 solution (E-5.44 ± 2.37; LE-5.55 ± 2.31). In group L, SEM images reveled a disorganized surface but fewer projections than in group W and LE showed fewer irregularities than W, E, and L. For bovine enamel, tissue loss in group L (13.90 ± 3.50) did not differ from that in group W (14.10 ± 2.98), and was higher than losses in groups E (5.70 ± 2.12) and LE (8.12 ± 2.56), which were statistically similar to each other. Groups W and L had similar aspects of demineralization, whereas groups E and LE showed homogenous surfaces. Surface-treated samples had no changes in their surfaces. CO2 laser was able to slightly prevent surface loss only on human enamel surface, but did not enhance the AmF/NaF/SnCl2 effect on the prevention of enamel erosion.
