Henoch-$Sch\ddot{o}nlein$ Purpura (HSP) is a systemic vasculitis involving small vessels with the deposition of immune complexes containing IgA and C3, which is characterized by associated skin, joint, renal, and gastrointestinal manifestations. Although there were several causes such as autoimmunity, infection, and drugs, it also can be presented as a form of vasculitidies associated with malignancies. We report a case of HSP developed during treatment for non-small cell lung cancer in a 66-year-old man. Multiple purpuric skin lesions occurred in both legs after the first cycle of chemotherapy, which was diagnosed as HSP by clinical and pathologic examinations. Due to the itching sensation, topical steroid was applied and the patient was improved 3 weeks later without a scheduled change in chemotherapy.

Backgrounds: The purpose of this study was to compare full thickness skin graft with inguinal skin to split thickness skin graft for coverage of the radial forearm free flap donor site. Patients and Methods: 25 patients who was reconstructed with radial forearm free flap for head and neck cancer were reviewed retrospectively. Results: The graft loss rates of full thickness skin graft were less than split thickness skin graft or split thickness skin graft with dermal substitutes. The recovery times of donor site and skin graft donor site of full thickness skin graft were also shorter than split thickness skin graft or split thickness skin graft with dermal substitutes. Skin texture and aesthetic results of donor site were improved and complications as itching and pain sensation were decreased. Conclusion: Full thickness skin grafts with inguinal skin should be considered for patients requiring a radial forearm free flap.

This study explored the appearance management experiences of breast cancer patients undergoing mastectomy. For data collection, one-on-one interviews were held with 18 Korean females diagnosed with breast cancer from the first stage to the third stage from 2008 to 2015. The data was analyzed through a three-step analysis of grounded theory. QSR NVivo 11.0 for Mac was applied in order to avoid biased results according to the subjective viewpoint of researchers. From open coding results, six paradigms and 15 categories were drawn. The results of axial coding showed that the psychological changes category was the central phenomenon. Additionally, three categories (skin changes, scalp/hair changes, and general reactions) were found to be causal conditions, and five paradigms (clothing behavior, skin care behavior, makeup behavior, scalp/hair-care behavior, and shopping behavior) were found to be action/interaction strategies. Last, selective coding integrated fragmented qualitative data through open coding and axial coding in order to derive explanatory narratives. A comprehensive examination of the appearance management behaviors of breast cancer patients suffering from extreme stress due to physical/psychological changes enables this study to provide a foundation for related studies to be activated in the clothing and textiles discipline.

Background: Messaging surrounding skin cancer prevention has previously focused on the general public and emphasized how or when activities should be undertaken to reduce solar ultraviolet radiation (UVR) exposure. Generic messages may not be applicable to all settings, and should be tailored to protect unique and/or highly susceptible subpopulations, such as outdoor workers. The primary objective of this study was to develop a set of tailored, practical, harm-reducing sun safety messages that will better support outdoor workers and their employers in reducing the risk of solar UVR exposure and UVR-related occupational illnesses. Methods: We adapted a core set of sun safety messages previously developed for the general population to be more applicable and actionable by outdoor workers and their employers. This study used an integrated knowledge translation approach and a modified Delphi method (which uses a survey-based consensus process) to tailor the established set of sun safety messages for use for outdoor worker populations. Results: The tailored messages were created with a consideration for what is feasible for outdoor workers, and provide users with key facts, recommendations, and tips related to preventing skin cancer, eye damage, and heat stress, specifically when working outdoors. Conclusion: The resulting tailored messages are a set of evidence-based, expert- approved, and stakeholder-workshopped messages that can be used in a variety of work settings as part of an exposure control plan for employers with outdoor workers.

다이오드 측정기(diode)와 유리 선량계(glass dosimeter)를 이용하여 체표면 선량측정을 시행하고 실제 방사선조사 영역에 조사되는 방사선량을 치료계획 시스템에서 계산된 방사선량과 비교하여 유리 선량계를 체표면 측정기로 활용할 수 있는 가능성을 확인하고자 하였다. 이를 위하여 유방암 치료로 방사선을 조사받는 환자 27명을 대상으로 다이오드 측정기와 유리 선량계를 같은 부위에 부착하여 각각의 위치에서 조사되는 방사선량을 측정하였다. 여기서 사용된 유리 선량계는 총 40개 중 재현성이 3% 이내인 28개의 소자만을 사용하였다. 환자의 치료 셋업 위치에 따라 네 부위에 각각 선량계를 부착하여 각 위치에서의 선량값을 측정하였다. 연구에 참여한 27명의 환자 모두에 대하여 180 cGy/fraction의 방사선을 조사하였다. 이때 같은 부위에 부착한 두 측정기가 나타내는 선량값의 차이는 최대 3.2%였으며, 치료계획 된 선량값과 비교했을 때 다이오드 측정기의 경우 평균 2.3%의 차이를 보였으며, 유리선량계의 경우 평균 3.4%의 차이를 나타내었다. 이로써 유리 선량계는 체표면 측정기로 활용할 수 있는 가능성을 보였다. 치료계획에서 계산된 선량값에 비해 두 종류 측정기로 측정한 선량값이 모두 적은 값을 나타내었으나, 이는 각각의 선량계가 가지고 있는 특성 오차의 영향과 선량계를 부착한 부위가 고정되기 쉽지 않고 움직이기 쉬운 부분이라는 신체적 특성의 영향에 따른 차이라 생각된다.

Melanoma of the skin is a malignant tumor, which incidence is still increasing. It was estimated that in the United States one person died from this cause every hour. The major risk factor of this disease is exposure to ultraviolet radiation, especially associated with the occurrence of sunburns. Patients diagnosed with distant metastases have median survival of 6-9 months. The aim of this paper was to identify the causes of delayed diagnosis of melanoma as diagnosis at an early stage seems to be the key to improve the survival rates. For this purpose, a search of medical databases such as PubMed, Google Scholar and Cancer Registers was conducted and an analysis of the literature from the years 1979-2013 was conducted.

Background: The standard radiotherapy (RT) fractionation practiced in India and worldwide is 50Gy in 25 fractions over 5 weeks to the chest wall or whole breast followed by tumour bed boost in case of breast conservation (BCS). A body of validated data exists regarding hypofractionation in breast cancer. We here report initial results for 135 patients treated at our center with the START-B type of fractionation. Materials and Methods: From May 2011 till July 2012, women with all stages of breast cancer (excluding metastatic), who had undergone BCS or mastectomy were planned for 40Gy in 15 fractions over 3weeks to chest wall/whole breast and supraclavicular fossa (where indicated) followed by tumour bed boost in BCS patients. Planning was done using Casebow's technique. The primary end point was to assess the acute toxicity and the cosmetic outcomes. Using cosmetic scales; patients were assessed during radiotherapy and at subsequent follow up visits with the radiation oncologist. Results: Of the 135 patients, 62 had undergone BCS and 73 mastectomy. Median age of the population was 52 years. Some 80% were T1&T2 tumours in BCS whereas most patients in mastectomy group were T3&T4 tumours (60%). 45% were node negative in BCS group whilst it was 23% in the mastectomy group. Average NPI scores were 3.9 and 4.9, respectively. Most frequently reported histopathology report was infiltrating ductal carcinoma (87%), grade III being most common (58%), and 69% were ER positive tumours, and 30% were Her 2 Neu positive. Triple negative tumours accounted for 13% and their mean age was young (43 yrs.) The maximum acute skin toxicity at the end of treatment was Grade 1 in 94% of the mastectomy grouppatients and 71% in BCS patients. Grade 2 toxicity was 6% in mast group and 23% in BCS group. Grade 3 was 6% in BCS group, no grade 3 toxicity in mastectomy patients and there was no grade 4 skin toxicity in any case. Post RT at 1 month; 39% of BCS patients had persisting Grade I skin reaction which was only 2% in mastectomy patients. At 3 months post RT, 18% patients had persisting hyperpigmentation. At 6 months 8% patients had persisting erythema in the BCS group only. Some 3% BCS and 8% mastectomy patients had lymph edema till the date of evaluation. Cosmetic outcome in BCS patients remained good to excellent 6 months post surgery and radiotherapy. 1 patient of BCS and 3 patients of mast had developed metastatic disease at the time of evaluation. Conclusions: Hypofractionated RT is well tolerated in Indian population with reduced acute skin toxicity and good cosmetic outcome. Regimens such as these should be encouraged in other centers to increase machine output time. The study is on-going to assess long term results.

Background Skin cancer is the most prevalent cancer by organ type and referral accuracy is vital for diagnosis and management. The British Association of Dermatologists (BAD) and literature highlight the importance of accurate skin lesion examination, diagnosis and educationally-relevant studies. Methods We undertook a review of the relevant literature, a national audit of skin lesion description standards and a study of speciality training influences on these descriptions. Questionnaires (n=200), with pictures of a circular and an oval lesion, were distributed to UK dermatology/plastic surgery consultants and speciality trainees (ST), general practitioners (GP), and medical students (MS). The following variables were analysed against a pre-defined 95% inclusion accuracy standard: site, shape, size, skin/colour, and presence of associated scars. Results There were 250 lesion descriptions provided by 125 consultants, STs, GPs, and MSs. Inclusion accuracy was greatest for consultants over STs (80% vs. 68%; P<0.001), GPs (57%) and MSs (46%) (P<0.0001), for STs over GPs (P<0.010) and MSs (P<0.0001) and for GPs over MSs (P<0.010), all falling below audit standard. Size description accuracy sub-analysis according to circular/oval dimensions was as follows: consultants (94%), GPs (80%), STs (73%), MSs (37%), with the most common error implying a quadrilateral shape (66%). Addressing BAD guidelines and published requirements for more empirical performance data to improve teaching methods, we performed a national audit and studied skin lesion descriptions. To improve diagnostic and referral accuracy for patients, healthcare professionals must strive towards accuracy (a circle is not a square). Conclusions We provide supportive evidence that increased speciality training improves this process and propose that greater focus is placed on such training early on during medical training, and maintained throughout clinical practice.
