Effects of the lower energy and pulse stacking in carbon dioxide laser skin tre...
Motta,Marcos Matias; Stelini,Rafael Fantelli; Calderoni,Davi Reis; Gilioli,Rovilson; Damiani,Gislaine Vieira; César,Carlos Lenz; Kharmandayan,PauloABSTRACT Purpose To evaluate the effect of fractional carbon dioxide (CO2) laser treatment using lower power associated with pulse stacking within collagen fibers, using second harmonic generation microscopy and computerized image analysis. Methods Twenty male Wistar rats aging eight weeks were used. Each treatment area received a single-pass CO2 fractional laser with different parameters. The 20 animals were d...
Basal cell carcinoma with compromised margins: retrospective study of managemen...
Fidelis,Maria Carolina; Stelini,Rafael Fantelli; Staffa,Leonardo Piropo; Moraes,Aparecida Machado de; Magalhães,Renata FerreiraAbstract Background: Non-melanoma skin cancer is the most common type of malignancy in the Western world, and surgical excision is the preferred approach. The approach adopted in the face of incomplete excisions of basal cell carcinoma is still controversial. Objectives: To compare the number of tumor recurrences after treatment for incompletely excised basal cell carcinoma. Methods: Selection and statistical a...
Blue nevus with satellitosis: case report and literature review
Oliveira,Ana Helena Kalies; Shiraishi,Ana Flávia de Melo Cavalcanti; Kadunc,Bogdana Victoria; Sotero,Patrícia de Carvalho; Stelini,Rafael FantelliAbstract: Blue nevus is a benign melanocytic lesion, typically asymptomatic and of unknown etiology. Many histological subtypes are recognized, the most commons being: common blue nevus, cellular blue nevus, and combined blue nevus. New rare variants have been described in the literature, with emphasis on eruptive blue nevus, plaque, agminate, linear, with satellitosis, disseminated, familial and targetoid. The...
Liquid silicone used for esthetic purposes as a potentiator for occurrence of p...
Antonelli,Raíssa Quaiatti; Calderoni,Davi Reis; Garcia,Igor Ferreira; Stelini,Rafael Fantelli; Fregonesi,Adriano; Kharmandayan,PauloABSTRACT CONTEXT: Lymphedema consists of extracellular fluid retention caused by lymphatic obstruction. In chronic forms, fat and fibrous tissue accumulation is observed. Genital lymphedema is a rare condition in developed countries and may have primary or acquired etiology. It generally leads to urinary, sexual and social impairment. Clinical treatment usually has low effectiveness, and surgical resection is f...
Lower energy and pulse stacking. A safer alternative for skin tightening using ...
Motta,Marcos Matias; Stelini,Rafael Fantelli; Calderoni,Davi Reis; Gilioli,Rovilson; Kharmandayan,PauloPURPOSE : To evaluate the effect of different energies and stacking in skin shrinkage. METHODS : Three decreasing settings of a fractional CO2 laser were applied to the abdomen of Twenty five Wistar rats divided into three groups. Group I (n=5) was histologically evaluated for microthermal zones dimensions. Groups II and III (n=10 each) were macroscopic evaluated with freeware ImageJ for area contraction immedi...
Cutaneous metastasis as the first manifestation of occult malignant breast neop...
Weimann,Ellem Tatiani de Souza; Botero,Erica Bruder; Mendes,Cinthia; Santos,Marcel Alex Soares dos; Stelini,Rafael FantelliAbstract Cutaneous metastases from primary internal malignancies represent 0.7-9% of patients with cancer. We report a 65-year-old female patient referred for evaluation of normochromic papules on the trunk and upper limbs that had been present for three months. A skin biopsy revealed diffuse cutaneous infiltration by small round cell tumors. Immunohistochemistry was positive for AE1/AE3, CK7, estrogen receptor...
Distribution of histological diagnoses of black and white skin in Campinas, dis...
Alvarez,Isabela Mamere; Puggina,Juliana; Machado,Helymar C.; Stelini,Rafael Fantelli; Florence,Michelle Etienne; Souza,Elemir Macedo deINTRODUCTION: Little is known about ethnic differences in the frequency of skin diseases, and even less in terms of Brazilian population, which is characterized by miscegenation. OBJECTIVE: To evaluate the distribution of skin disorders in black and Caucasian patients through pathological specimens. METHODS: 826 biopsies from black-skinned individuals and 1,652 from white-skinned patients were retrieved and stu...
