Clinical Impact of Pelvic Sentinel Lymph Node Biopsy for Vulvar Squamous Cell Carcinoma.

BACKGROUND/AIM: This study investigated the clinical impact of resection of pelvic sentinel lymph nodes (PSLNs) in squamous cell vulvar cancer (SCVC). PATIENTS AND METHODS: Sixty-two groins of 33 patients with SCVC who underwent sentinel lymph node (SLN) resection between 2010 and 2021 at the University Hospital of Cologne, Germany, were analyzed in this retrospective cohort study. The frequency of additionally resectable PSLNs, histological findings, and count rates were analyzed and compared to the findings for inguinal sentinel lymph nodes (ISLNs). RESULTS: In all patients and in 61 (98%) of the 62 radiolabeled groins, at least one SLN could be resected. Five (8%) of the 62 groins had histologically confirmed lymph node metastases (4/33 patients, 12%). Twenty (33%) of the 62 groins underwent additional PSLN resection. Resection of these PSLNs was feasible without causing an additional burden for the patients. None of the PSLNs showed signs of tumor infiltration. Information on the extent of radioactivity for ISLNs and simultaneously for PSLNs, expressed as count rate of intraoperative measurement with the gamma probe, was available for 20 (32%) groins. In three (15%) of these cases, the highest count rate in a SLN was found in a PSLN and not in an ISLN. CONCLUSION: Resection of PSLNs is feasible and can be performed without short-term complications. In patients with early SCVC, resection of PSLNs is not necessary, even in those with early infiltration of inguinal lymph nodes. The intraoperative count rate of SLN is not relevant for the decision to perform resection.

Care needs and self-induced measures of women with postpartum pelvic floor disorder- Results of a social media-based survey of 2930 women.

INTRODUCTION: Pelvic floor disorders (PFD) occur in about 40% of women after delivery. Less is known about the intervention and care needs of women with postpartum PFD. The aim of this analysis was to analyze care needs and self-initiated measures to strengthen the pelvic floor in postpartum women in relation to incontinence and sexual dysfunction. Furthermore, influencing factors for self-initiated measures were evaluated. PATIENTS AND METHODS: An anonymous online survey (via LimeSurvey) was conducted between September and October 2022 and distributed via social media (Instagram and Facebook). The survey explicitly addressed mothers with and without pelvic floor disorders up to 5 years postpartum (inclusion criteria). Validated instruments were employed to assess incontinence (ICIQ-SF) and sexual functioning (PISQ-IR: Condition Impact). The questions on the use of services and preventive measures, as well as on the interaction with a gynecologist, were based on self-developed items. RESULTS: In total, 49.4% of the participants of the survey showed symptoms of urinary incontinence (UI). Furthermore, only 40.3% (n = 241) of women were actively asked by their gynecologists for the occurrence of UI or PFD among those who suffered from PFD. Overall, 79.3% of the participants of the survey with UI underwent measures to deal with the complaints. The ICIQ-SF Score was significantly associated with all self-induced measures. High School diplomas and academic degrees were associated with the use of love balls (p < 0.05). CONCLUSION: The results of the study show the unmet needs of postpartum women. PFD should be addressed more frequently in the outpatient setting. Furthermore, more systematic information about the treatment of PFD could help to address unmet information needs and improve interventions.

Sonographic Assessment of Breast Implants Using Strain Elastography and Shear Wave Elastography in an Animal Model.

BACKGROUND/AIM: To date, magnetic resonance imaging (MRI) remains the gold standard for diagnosing breast implant rupture. As MRI is an expensive procedure with limited availability, the improvement of sonographic assessment is desirable. A potentially useful tool in this regard is elastography. To evaluate the diagnostic benefits of strain elastography and shear wave elastography under standardized conditions we developed an animal model. MATERIALS AND METHODS: An animal model was created by preparing an implant site in a chicken breast, imitating tissue layers covering a breast implant after mastectomy. Different broken and intact implants were inserted. Thereby, measurements were performed using strain elastography and shear wave elastography. For strain elastography, the resulting images were investigated on repeated patterns. The data generated by shear wave elastography were analyzed for significant differences between the ruptured and intact implants. RESULTS: The animal model using chicken breast generated realistic images and measurements comparable to those of a human breast. Hence, ruptured and intact implants could be compared under standardized conditions. Statistical analysis showed no significant difference between intact and ruptured implants with respect to the data generated by shear wave elastography. Qualitative analysis using strain wave elastography showed different patterns between intact and ruptured implants in the animal model. Intact implants showed a characteristic sonographic image of three layers in certain levels. CONCLUSION: Shear wave elastography does not seem to produce reliable data for the evaluation of breast implants, whereas qualitative analysis using strain elastography might be a useful tool to improve diagnostic accuracy.
