Photodynamic therapy as an alternative treatment in patients with invasive cutaneous SCC where surgery is not feasible: Single center experience.

The aim of this study was to demonstrate the efficacy of 5-aminolevulinic acid photodynamic therapy (ALA-PDT) as an alternative treatment in cutaneous squamous cell carcinoma (cSCC) patients who are not fit for surgery. Thirty-three invasive cSCC patients who, for some reasons, cannot undergo surgery were enrolled in this study. All patients received plum blossom needle (PBN) pretreated ALA-PDT combined with topical application of 5% imiquimod cream. Two patients dropped the study because of severe pain and two patients discontinue treatment due to lack of response. Of 29 patients, who completed the treatment, 5 patients had complete response after 2-9 sessions of PDT and these patients had no recurrence till 18 months after treatment. Twenty-four patients achieved partial response and are satisfied with treatment outcome in terms of decreased symptoms and improved quality of life. PBN pretreated PDT in combination with topical imiquimod may be a viable treatment option for non resectable cSCC lesions.

Evaluation of 5-aminolevulinic acid-mediated photorejuvenation of neck skin.

OBJECTIVE: To evaluate the outcomes of the combination of red light or intense pulsed laser (IPL) with 5-aminolevulinic acid (ALA)-mediated photodynamic therapy (PDT) in the treatment of photodamaged neck skin. METHODS: The anterior of the neck was divided into four 2 cm × 2 cm sections and randomly assigned to red-light, red-light-PDT, IPL or IPL-PDT group. ALA cream of 5% was applied to PDT regions for 2h prior to light irradiation. Treatment was repeated once. The stratum corneum (SC) hydration, transepidermal water loss (TEWL), L(*), a(*), b(*) values, melanin index (MI), erythema index (EI), skin elasticity and skin thickness were examined by a blinded investigator. The function and volume of thyroid were also measured. RESULTS: After red-light-PDT, IPL-PDT and IPL treatment, the appearance of photoaging lesion was improved. The SC hydration, L(*) value, elasticity and thickness increased, whereas the TEWL and MI value decreased. These changes in red-light-PDT and IPL-PDT group were more obvious than IPL group. The a(*) and EI value increased in red-light-PDT group. No significant change was noticed in red-light group. Partial irradiation of the thyroid did not affect the function and volume of the thyroid. CONCLUSION: IPL-PDT and red-light-PDT showed better rejuvenation effect than IPL or red light alone on the neck skin.

A community-based participatory research approach to understanding pap testing adherence among Vietnamese American immigrants.

OBJECTIVE: To explore factors potentially influencing Pap testing practices among Vietnamese American immigrant women (VIW, foreign-born) and describe their awareness of cervical cancer screening resources in their community. DESIGN: Descriptive study guided by the ecological model and community-based participatory research principles. SETTING: Portland, Oregon, metropolitan area. PARTICIPANTS: Vietnamese American immigrant women (211) who were age 21 and older. METHODS: We used descriptive statistics and logistic regression analyses to analyze a self-administered questionnaire that was pretested and translated using a team approach. RESULTS: Approximately 74% of VIW who completed the survey reported at least one Pap test, and 69% reported Pap testing history adherent to national guidelines. The factor most strongly associated with Pap testing receipt was suggestion from a friend, followed by longer residency in the United States, lower perceived common barriers, and lower perceived cultural barriers, for example, lack of family support and use of Eastern/Asian medicine. The factor most strongly associated with guideline adherence was having health insurance, followed by a recommendation from a physician or nurse practitioner. Only 11% of VIW knew where to obtain a free or low-cost Pap tests. CONCLUSION: Nurses can influence rates of Pap testing among VIW by providing health education through outreach programs targeted at lay health workers and their social networks, identifying at-risk patients such as recently immigrated women, reducing perceived common and cultural barriers to Pap testing, and helping women seek alternative payment options if they lack health insurance. Primary health care providers should be reminded of their essential role in increasing Pap testing adherence.

Prioritizing prevention: culture, context, and cervical cancer screening among Vietnamese American women.

Few studies have investigated what Vietnamese American women believe about the Pap smear or how those beliefs might influence behavior. Thirty-one Vietnamese American women recruited through snowball sampling were interviewed about their beliefs regarding the Pap smear. Interviews were qualitatively analyzed using a theoretically informed, inductive approach. The women interviewed emphasized the importance of primary prevention of disease through culturally-informed personal health regimens. They were also largely unfamiliar with the Pap smear, but believed that gynecological exams in general were effective and necessary for disease detection. Finally, when access to gynecological care was difficult, women's faith in their own preventive behaviors helped alleviate their concerns over lack of care. While culturally associated beliefs do not simply "cause" Vietnamese American women to seek or avoid Pap smears, they do influence screening behaviors to a greater or lesser degree, depending on other contextual variables.
