The First Application of Nanoelectrochemotherapy in Feline Oral Malignant Melanoma Treatment—Case Study

Background: The aim of this study was to present the first domestic animal trial of nanosecond electroporation with chemotherapy and CO2 laser surgery. Methods: sixteen-year-old domestic cat with diagnosed melanoma on oral cavity was the case used in the study. Firstly, CO2 laser surgery was used for the removal of most of tumor mass. Then nanoelectrochemotherapy with bleomycin was applied including appropriate margin of healthy tissue. A 15 ± 4 kV/cm × 15 ns pulsing protocol was employed with a total of 800 ± 100 pulses. Only one session of nanoelectrochemotherapy (nanoECT) was performed. Results and conclusions: during the next two weeks areas of focal necrosis were replaced by the granulation tissue. Complete wound healing was observed four weeks after initial treatment. After 15 weeks post treatment, no local recurrence was apparent.

Treatment of Bartholin gland cyst with CO2laser

ABSTRACT Objective To describe the results of treatment with CO2 laser for Bartholin gland cysts. Methods Thirty-one women with Bartholin gland cysts were treated with CO2laser at an outpatient´s setting. Skin incision was performed with focused laser beam, the capsule was opened to drain mucoid content, followed by internal vaporization of impaired capsule. Results There were no complications. Five patients had recurrence of the cyst and were submitted to a second and successful session. Conclusion CO2 laser surgery was effective to treat Bartholin gland cysts with minimal or no complications, and can be performed at an outpatient´s setting.
