    Colagenosis perforante reactiva adquirida. Caso clínico
    (Sociedad Médica Santiago, 2010) Cárdenas de la Torre, Consuelo Paz; Bello Cisternas, Cristina del Carmen; Uribe González, Pablo Francisco; Romero Gallardo Williams Andres; González Bombardiere, Sergio Javier
    Acquired reactive perforating collagenosis is a perforating dermatosis characterized by transepidermal elimination of collagen. It is frequently associated to diabetes mellitus and chronic renal insufficiency, but it is also related to other systemic diseases. The lesions tend to resolve once the underlying condition is treated. We report two patients with the condition. A 65 year-old diabetic female on hemodialysis consulted for multiple itching cutaneous ulcers lasting one year. On physical examination, hyperpigmented papules and nodules were observed. A 65 year-old female with chronic renal failure in hemodialysis consulted for itching lesions in hands, forearms and arms. On physical examination, hyperpigmented lesions with ulcers, erosions and crusts were observed. In both cases, the pathological study of the lesions disclosed a reactive perforating collagenosis.

    Management of periocular keratinocyte carcinomas with Mohs micrographic surgery and predictors of complex reconstruction: a retrospective study
    (2023) Peirano, Dominga; Vargas Mancilla, Sebastián Enrique; Hidalgo Acuña, Leonel Esteban; Donoso Mendieta, Francisca; Abusleme, Eugenia; Sanhueza Zamora, Felipe Alberto; Cárdenas de la Torre, Consuelo Paz; Droppelmann, Katherine; Castro Ayala, Juan Camilo; Uribe González, Pablo Francisco; Zoroquiain Velez, José Pablo; Navarrete Dechent, Cristián Patricio
    Background: Skin cancer is the most frequent cancer worldwide and the most frequent periocular tumor. Keratinocyte Carcinomas (KC) located in periorificial areas, such as periocular tumors, are considered high-risk tumors. Mohs Micrographic Surgery (MMS) is considered the first line for the treatment of high-risk KC, providing a lower recurrence rate than conventional wide excision. Objective: To describe the clinical-pathological features of periocular KC treated with MMS in a tertiary university center in Chile. Methods: A single-center, retrospective study of patients with KC located on the periocular area, that underwent MMS between 2017---2022. MMS details were recorded. Results: One hundred thirteen patients with periocular carcinomas were included. The mean age was 59 ± 13 years; 52% were women. The most frequent location was the medial canthus (53%), followed by the lower eyelid (30.1%). The most frequent BCC histology was the nodular variant (59.3%). Regarding MMS, the average number of stages was 1.5 ± 0.7, and 54% of the cases required only 1 stage to achieve clear margins. To date, no recurrence has been reported. Tumors larger than 8.5 mm in largest diameter or 43.5 mm2were more likely to require complex reconstruction. Study limitations: Retrospective design and a relatively low number of patients in the SCC group. Possible selection bias, as larger or more complex cases, may have been referred to oculoplastic surgeons directly.

    Manifestaciones cutáneas de amiloidosis sistémica como clave diagnóstica: caso clínico
    (2012) Fich Schilcrot, Felix Jaime; Chahuán Y., Marco; Farías Navarro, María Magdalena; Cárdenas de la Torre, Consuelo Paz; Abarzúa Araya, Álvaro Rodrigo; Araya C., Gabriela; González B., Sergio
    Systemic amyloidosis is a rare disease that can affect any organ. Its clinical manifestations are varied and nonspecific. The skin involvement of this disease is common and can be easily recognized on physical examination. We report a 57-year-old male presenting with a two years history of malaise, dyspnea and myalgias. On physical examination, ungueal dystrophy, orange pigmentation of eyelids with periocular petechiae and mild macroglossia were observed. Incisional biopsies of the eyelids, cheeks and hands were obtained. The pathological study demonstrated amyloid deposits. Since protein electrophoresis was normal, the diagnosis of AA amyloidosis was postulated.

    Oral and written counseling is a useful instrument to improve short-term adherence to treatment in acne patients: a randomized controlled trial
    (2015) Navarrete Dechent, Cristián Patricio; Curi Tuma, Maximiliano; Nicklas, Claudia; Cárdenas de la Torre, Consuelo Paz; Perez-Cotapos, Maria Luisa; Salomone, Claudia
    Background: Therapeutic success in acne patients not only depends in the appropriate selection of drugs but also on patient’s treatment adherence or compliance. Lack of adherence is a very important problem both in general medicine and in dermatologic practice. Objective: To evaluate the impact of oral and written counseling in adherence to treatment in acne patients. Patients and Methods: Eighty patients were randomized into a two study groups of 40 patients each in which instructions were given in a written note (besides oral counseling) and reinforced by a telephone within 15 days of onset, and a control group that received indications as usual (oral counseling in-office only). Both groups were followed-up, evaluating adherence to treatment according to self-reporting of patients at 30, 60, 90 days and 6 months. Results: Better adherence to treatment was observed in the intervention group, being statistically significant only in the first month of treatment (80% versus 62%, p = 0.043). The beneficial effect of written counseling plus a phone call diluted in subsequent months. Conclusion: Written counseling significantly improves adherence in the first month of treatment. Good adherence could also lead to more effective treatments so it seems reasonable to use time and resources to optimize adherence to treatment.
