BACKGROUND Public awareness for BCC is particularly important, as its major risk factors — increased sun exposure and number of sunburns — are largely preventable. OBJECTIVE Determine whether social media posts from celebrities has an affect on public awareness of basal cell carcinoma. METHODS We used Google Trends to investigate whether public awareness for basal cell carcinoma (BCC) increased following social media posts from Hugh Jackman. To forecast the expected search interest for BCC, melanoma and sunscreen in the event that each celebrity had not posted on social media, we used the autoregressive integrated moving average (ARIMA) algorithm. RESULTS We found that social media posts from Hugh Jackman, a well-known actor, increased relative search interest above the expected search interest calculated using an ARIMA forecasting model. CONCLUSIONS Our results also suggest that increasing awareness by Skin Cancer Awareness Month may be less effective for BCC, but a celebrity spokesperson has the potential to increase awareness. BCC is largely preventable, so increasing awareness could lead to a decrease in incidence.

Sun Exposure

Background: The development of knowledge concerning the role of sun exposure in causing skin cancer has been a gradual one. Objective: This article reviews the article by Urbach who used manikin coated with an ultraviolet dosimeter to see exactly where on the head and neck the exposure was greatest. Conclusion: Urbach showed that the areas of greatest sun exposure on his manikins corresponded with the location of 95% of squamous cell carcinoma and 66% of basal cell carcinoma. He also clearly showed the importance of scattered sky and reflected radiation.

Background/Aim. Basal cell carcinoma (BCC) is the most common form of skin cancer in the white population. Increasing incidence of BCC imposes the requirement to identify the risk factors due to eventual preventive action. The aim of this study was to assess the role of some constitutional characteristics in development of BCC among the Montenegrin population. Methods. A case-control study was conducted at the Dermatology Department of Clinical Center of Montenegro in Podgorica from 2002?2003. The study group included 100 histopatologically confirmed BCC cases, while the control group consisted of 100 patients from the same department, who did not present skin cancer and who were individually matched to the cases by sex and age (?5 years). All participants were interviewed using an epidemiological questionnaire. For statistical analysis t test and McNemar ?2 test for matched pairs and multivariate logistic regression analyses were used. Results. The risk for development of BCC was increased among the persons with lighter hair color (t = 4.63; df = 99; p < 0.001), fair skin (t = 2.37; df = 99; p = 0.020), lighter eyes color (t = 2.86; df = 99; p = 0.005), with nevuses (OR = 13.13; p = 0.025; 95% IP = 1.39-12.03), and among those whose skin tone after sun exposure remained light (OR = 3.14; p = 0.001; 95%IP = 1.59-6.18). Conclusion. Our study confirmed the significance of constitutional characteristics such as lighter hair color, fair skin, lighter eyes color, and the presence of nevuses in the development of BCC. .

Background: The purpose of this study was to formulate, characterize and in-vitro cytotoxicity of 5-Fluorouracil loaded controlled release nanoparticles for the treatment of skin cancer. The patents on nanoparticles (US8414926B1), (US61654404A), (WO2007150075A3) etc. helped in the selection polymers and method for the preparation of nanoparticles. Methods: In the present study nanoparticles were prepared by simple ionic gelation method using various concentrations of chitosan and sodium tripolyphosphate (TPP). Several process and formulation parameters were screened and optimized using 25-2 fractional factorial design. The prepared nanoparticles were evaluated for particle size, shape, charge, entrapment efficiency, crosslinking mechanism and drug release study. Results: The optimized 5-Fluorouracil loaded nanoparticle were found with particle size of of 320±2.1 nm, entrapment efficiency of 85.12%± 1.1% and Zeta potential of 29mv±1mv. Scanning electron microscopy and dynamic light scattering technique revealed spherical particles with uniform size. The invitro release profile showed controlled release up to 24 hr. Further study was carried using A375 basal cell carcinoma cell-line to elucidate the mechanism of its cytotoxicity by MTT assay. Conclusion: These results demonstrate that the possibility of delivering 5-Fluorouracil to skin with enhanced encapsulation efficiency indicating effectiveness of the formulation for treatment of basal cell carcinoma type of skin cancer.

Background: The purpose of this study was to formulate, characterize and conduct in vitro cytotoxicity of 5-fluorouracil loaded polymeric electrospun nanofibers for the treatment of skin cancer. The patents on electrospun nanofibers (US9393216B2), (US14146252), (WO2015003155A1) etc. helped in the selection of polymers and method for the preparation of nanofibers. Methods: In the present study, the fabrication of nanofibers was done using a blend of chitosan with polyvinyl alcohol and processed using the electrospinning technique. 5-fluorouracil with known chemotherapeutic potential in the treatment of skin cancer was used as a drug carrier. 24-1 fractional factorial screening design was employed to study the effect of independent variables like the concentration of the polymeric solution, applied voltage (kV), distance (cm), flow rate (ml / hr) on dependent variables like % entrapment efficiency and fiber diameter. Results: Scanning electron microscopy was used to characterize fiber diameter and morphology. Results showed that the fiber diameter of all batches was found in the range of 100-200 nm. The optimized batch results showed the fiber diameter of 162.7 nm with uniform fibers. The tensile strength obtained was 190±37 Mpa. Further in vitro and ex vivo drug release profile suggested a controlled release mechanism for an extended period of 24 hr. The 5-fluorouracil loaded electrospun nanofibers were found to decrease cell viability up to ≥50% over 24 hr, with the number of cells dropping by ~ 10% over 48 hr. As the cell viability was affected by the release of 5-fluorouracil, we believe that electrospun nanofibers are a promising drug delivery system for the treatment of Basal Cell Carcinoma (BCC) skin cancer. Conclusion: These results demonstrate the possibility of delivering 5-Fluorouracil loaded electrospun nanofiber to skin with enhanced encapsulation efficiency indicating the effectiveness of the formulation for the treatment of basal cell carcinoma type of skin cancer.

SUMMARY Basosquamous carcinoma (BSC), as described in 1910, is a distinctive variety of skin cancer and its etiology and pathological characteristics have generated much controversy over the years. Currently, BSC is considered a basal cell carcinoma (BCC) subtype with aggressive behavior and greater tendency for recurrence and metastases. We present a clinical case recently reported in our unit.

Basal cell carcinoma is the most commonly seen nonmelanoma skin cancer which is rarely encountered in the childhood period. An 11-year old child was admitted to our clinic due to an erythematous and a slightly pigmented lesion with a3×4 cm diameter on his posterior scalp. Macroscopically, the lesion was excised with a 10 mm safety margin. Pathologic examination revealed a basal cell carcinoma. No symptoms or signs of a syndrome were observed both in the patient and his family.
