RESUMO
Mohs paste (MP) is a topical treatment that can help relieve the symptoms of self-destructive skin lesions caused by malignant tumors. Despite the potential benefits of MP in improving the quality of life of patients, its use in home-based care is limited due to various obstacles. In this study, we developed a 1-mm-thick MP gauze sheet, which allowed us to apply the MP treatment at home to a patient with breast cancer. After three weekly treatments, the patient’s main symptoms, including itchiness, odor caused by exudates, and mobility issues, showed improvement. By using MP as a sheet, we overcame the obstacles associated with its use, such as alterations in the physical properties and the risk of damage to healthy skin tissue. Additionally, we reduced the treatment duration and need for trained personnel. Our findings suggest that the MP treatment can effectively control the symptoms of patients in home-based care, consistent with prior research.
RESUMO
A man in his seventies sustained continuous bleeding from local recurrence at the residual rectal stump after Hartmann's surgery for rectal cancer. This patient declined chemotherapy and radiation therapy and conventional local anti-hemorrhagic treatments had not been effective. To assess the risk of Mohs' paste application to the rectal recurrence area, we checked the anatomical structures surrounding the application site by a CT study. In addition, two reasons we evaluated this Mohs' paste treatment to the rectal recurrence would be very safe were as follows: 1. A small amount of Mohs' paste was needed for the small rectal bleeding site. 2. Mohs' paste would not be applied to the rectum used for stoma. To avoid applying Mohs' paste to the neighbouring normal structures, a gauze coated with Mohs' paste was inserted into the rectum and placed only on the local recurrence site. Petroleum jelly was applied to the surface of normal rectal mucosa to prevent fixation. Bleeding and malodorous effusion decreased significantly without side effects such as pain, bleeding, or ulceration. Thereafter, additional fixation was not necessary. When all the other antihemorrhagic modalities are not available, Mohs' paste could be used for bleeding or an effusion from non-superficial tumors after a thorough risk assessment on this treatment.
RESUMO
Mohs' paste is a histopathological fixative with zinc chloride as the main ingredient. It has been applied to perform chemosurgery of skin tumors. In recent years, this paste has been reportedly very effective for control of various symptoms of skin metastasis in inoperable advanced cancer, such as pungent odor and hemorrhage in the field of palliative care. Shigeyama et al. modified the composition of the original Mohs' paste in order to regulate its viscosity; they added glycerin to a mixture of zinc chloride and zinc oxide. However, there may be difficulty in pasting this agent to a target region, because of its very high viscosity. Therefore, we devised two methods to overcome this difficulty; one was to paint the surface of a small piece of gauze with Mohs' paste, and the other was to apply the paste directly on the gauze and apply it to a lesion. We called the above two modifications, "Mohs' gauze method A and B." Mohs' gauze was used for the treatment of hemorrhage, pungent odor and huge exudate from a metastatic skin tumor of gastric cancer. These conditions disappeared without any side effects. We did not recognize the difference in fixation effect of the lesion between the conventional Mohs' paste method and our Mohs' gauze methods. Our method should make the Mohs' paste easier to apply, and might extend its indication. Palliat Care Res 2011; 6(1): 324-329
RESUMO
In Palliative care, we meet patients with easy-bleeding superficial malignant tumors, such as head and neck cancer, skin metastasis of all kinds of cancer and unresectable breast cancer. But it is not easy to control bleeding even though we use various means, and many doctors have difficulties in stopping bleeding. We report a case with a recurrent tumor of pharyngeal cancer that showed easy-bleeding and discharged massive exudates. Although she received several alcohol local injections because of bleeding of the tumor, she needed a dressing change over 5 times in a day. It made her QOL worse. In this case, we used Mohs paste and after using it, the surface had been fixed and dried up, resulting in a decrease in bleeding, exudate, frequency of dressing change and bad odor. Mohs paste was made of distilled water, zinc chloride, zinc starch and Glycerol. Zinc chloride changes to zinc ion by water in the wound and makes protein cohere and thereafter tissues, vessels and cell membrane of bacteria are fixed chemically. We could stop bleeding for 15 days with only 20 minutes contact with Mohs paste, and massive exudates and bad odor decreased. Mohs paste, which is made in your hospital pharmacy with cheap materials, can be used for bleeding or massive exudates repeatedly if there is not a thick blood vessel anatomically under the tumor. It was effective to improve her QOL. Palliat Care Res 2009; 4(2): 346-350
