Genomic bases of non-syndromic basal cell carcinoma: literature review

Introduction: Non-melanoma skin neoplasms represent the most frequent type in both sexes globally, with basal cell carcinoma being the most prevalent, representing 75 to 80% of cases. In Brazil, the number of new cases expected for the triennium 2020-2022 will be 83,770 in men and 93,160 in women, corresponding to an estimated risk of 80.12 new cases for 100,000 men and 86.65 new cases for 100,000 women. This data demonstrates the great importance of genomic knowledge in the genesis of sporadic basal cell carcinoma. Objective: To describe the main genes and molecular markers involved in the predisposition and pathogenesis of non-syndromic basal cell carcinoma. Methods: Literature review in the main databases NCBI-GTR, ClinVar, ClinGen, MedGen, OMIM and GeneReviews, using as descriptors: "BCC" and "basal cell carcinoma". Inclusion criteria: Portuguese or EnGLIsh language, articles on sporadic BCC. Results: Thirteen articles were selected for analysis. The analysis revealed a robust hedgehog pathway link in the genesis of sporadic basal cell carcinoma, with the main genes involved represented by PATCH1, PATCH2 and smoothened. The variants with the highest clinical significance were SMO-M2, PTCH1 and PTCH2-Δ22. The mutation most found was related to the action of UVB, being represented by the substitution of C>T or CC>TT at the pyrimidine site, both in PTCH and in SMO. Conclusion: Extremely important to professionals working in the diagnosis and treatment of BCC, including plastic surgeons, as this way they can better conduct their cases, with more accurate diagnoses and prevention approaches based on the individual susceptibility of each patient, as well as targeted therapies and individualized with better success rates

Description of the S-Apple mixed rotation and transposition flap: preliminary note

Introduction: The flaps, whose function is to reduce or redirect tension during a closure, are classified based on their primary movement: transposition, advancement, and rotation, each with its characteristics, indications, and peculiarities. Combining the qualities of the transposition flaps with those of rotation, which make up the S-Apple flap, makes it more versatile and with better aesthetic results than the bilobed flap, which denotes the archetype for the appearance of the S-Apple. Method: Having the rotation and transposition flaps as an archetype, four flaps are made in the S-Apple flap, which are rotated and transposed to close the defect. This is excised in a circular format for the oncological safety of margins. The “S” of the flap is traced at a 30° angle in relation to the defect. The arm dimension must be the same diameter as the defect, with the flaps transposed as in a z-plasty, and the flap rotated to cover the defect, resulting from the exeresis of the lesion. Results: No necrosis, infection, dehiscence, recurrences, trapdoor scars, or rotation point elevation were observed. The scars were classified as satisfactory and extremely satisfactory. Conclusion: The S-Apple flap proved versatile and easy to mark with excellent aesthetic and functional results

Oxandrolone use in adult burn patients. Systematic review and meta-analysis

PURPOSE:This study is a systematic literature review and meta-analysis concerning the use of a testosterone synthetic analog, oxandrolone, and its use in severe adult burns.METHODS:Randomized prospective clinical studies, in English, Portuguese or Spanish, were sought on the following databases: MEDLINE, COCHRANE, EMBASE and LILACS. There was no restriction in relation to the publication date.RESULTS: This search produced 24 studies on MEDLINE and twelve articles were presented on the COCHRANE database .Sixteen were excluded due to the title not being related to this search or by including children. Of the eigth residual studies, after adaptation to the inclusion criteria, only four were selected. After analyzing the results, two were discarded since they did not present adequate patient characterization and the facts on these articles were analyzed differently from the others, hindering the meta-analysis.CONCLUSION:The analysis of the available data demonstrated significant benefits (p<0.05) considering lesser loss of corporal mass, lesser nitrogen loss, and shorter donor area healing time, when Oxandrolone was used, comparatively with the control group (placebo or not).Federal University of São PauloUNIFESPSciEL

Clinical classification of brow ptosis

INTRODUCTION: The study of the eyebrow is a great challenge for plastic surgery because of its complex relationship with facial structures. The present study aims to describe a clinical classification of brow ptosis. METHODS: A cross-sectional study with patients of both sexes and ages ranging from 18 to 100 years, subdivided into 3 groups according to age. Group 1: 18 to 30 years of age, Group 2: 31 to 60 years of age, and Group 3: 61 to 100 years of age. Three measurements were taken on each side by different examiners blinded to each other's results. RESULTS: A total of 90 patients, with ages ranging from 18 to 94, including 39 (43.3%) men and 51 (56.7%) women, were studied. Group 1, with a mean age of 26.7 years was considered normal, with mean brow ptosis of 2.14 cm. In Group 2, with a mean age of 44.2 years, the mean brow measurement was 1.9 cm. In Group 3, the mean age was 72.6 years and the mean brow measurement was 1.27 cm. The table outlining the brow ptosis classification assigns a degree of ptosis to each interval, ranging from I to IV. Each degree was correlated with a numerical range in which > 1.8 cm is normal, 1.7-1.5 cm corresponds to degree I ptosis, 1.4-1.2 cm to degree II ptosis, 1.1-0.9 cm to degree III ptosis, and < 0.8 cm to degree IV ptosis. Surgery was indicated for degrees II, III, and IV. CONCLUSION: The objective measurement of brow tail position enabled classification of the degree of ptosis and guides surgical decision-making

Methods: Data were removed of medical records and follow-up data were obtained from clinical records and direct contact with patients. A total of 39 patients were studied between January 1996 and December 2005. RESULTS: The median age was 47 years (range 14-70). There were 33 males and six females. Eleven (25.5%) patients presented Marfan syndrome and one (2.5%) Turner syndrome. Nineteen (48.5%) patients had hypertension, eight (20.5%) had history of smoking, six (15.5%) had history of alcoholism, eight (20.5%) had dyslipidemia, two (5.0%) had diabetes and one (2.56%) had myocardial infarct previously. Twenty-eight (72%) patients were in II-III NYHA class in the moment of the surgery. Annulo-aortic ectasy was present in 14 (35.9%) patients and aortic aneuryms in 16 (41%). The median time in intensive care unit was 8.79 days with range 2-23 days. Four (10.0%) patients underwent an emergency opertation and 35 (90%) elective. The overall hospital mortality was 5% (2/39). The event-free survival is 94.87% at 1 year and 84.61% at in 5 and 10. The median time of follow-up was 46.5 months (range 14-120 months). CONCLUSION: The Bentall and De Bono technique obtained excellent results in the short-term and long-term, which support the continued use of the compositive graft technique as the preferred method of treatament for patients with aortic root disease.
