A 77-year-old female patient submitted to excision of a basal cell carcinoma, resulting in an oval shaped defect with 20x25mm in diameter and exposure of the medial portions of alar cartilages. The reconstruction was perfor- med with transposition of muscle flaps from nasalis muscle in order to obtain a suitable vascular bed for a full-thickness skin graft harvested from a glabelar fold. The final result was cosmetically acceptable. Nasalis muscle flap associated with a full-thickness skin graft allows a single step reconstruction of nasal tip when exposure of cartilage without pericondrium occurs. Muscle flaps offer a better vascular supply for the skin graft, being a good alternative to local flaps or interpolated flaps, with a simpler surgical technique and achieving acceptable cos- metic results.KEYWORDS – Nose; Pele; Rhinoplasty;...
Introduction: Internet access for health information has risen in recent years and is currently used by 30% of Portuguese. Regarding sexually transmitted infections (STI), the information provided on the Internet should focus on preventive education and orientation of patients for medical assistance. Objective: Evaluation of the in- formation concerning STI, provided on Internet resources, accessed by the patients of our Venereology consultation. Methods: Every patient attending this Venereology clinic during a six-month period (August 2010 till January 2011), answered to a questionnaire on the previous use of the Internet to obtain information about STI. The three most often mentioned websites (for the five most common conditions and STI screening) were systematically reviewed and the re- sults displayed as a score (0-8). Results: A t...
Stevens-Johnson syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are uncommon mucocutaneous der- matosis with a potentially fatal outcome, mostly secondary to drug administration. The aim of this retrospective study was to evaluate the clinical and evolutive characteristics of the patients with SJS and TEN admitted to the Dermatology Department of Coimbra University Hospital, between June/2000 and June/2010. 38 patients (27 women and 11 men) were included, with a mean age of 58.5 years (±21,63 years, 14-88 years), 26 with SSJ, 4 with SJS-TEN overlap and 8 with TEN. Involve- ment of oral, ocular and genitalia mucous membranes were present in 35, 30 and 13 patients respectively, with involvement of at least two in 31 patients. Drugs were the causative factors in 81.6% of patients: allopurinol in 36%, antibiotics in 23%, anticonvulsant...
Introduction: patient safety is a growing concern in healthcare management. The main objectives of our work were the detection of potentially avoidable errors in the treatment of patients with melanoma and search for solutions to improve patient safety. Material and methods: FMEA (Failure Mode and Effect Analysis) was used for analysis of the potentially avoidable errors in melanoma surgery. Results: Failure to attend surgery or post treatment follow up and wrong site surgery were the most potentially dangerous procedural errors found in melanoma treat- ment. An informatic application was used to improve communication between the laboratory and the clinician and to avoid both failures to deliver a positive result to the patient and loss of follow up. Conclusions: dermatologists, working together with other healthcare workers, must acti...
A cicatrização de feridas constitui um processo complexo e coordenado, envolvendo a interacção entre células e vários sistemas mensageiros. Este processo pode dividir-se em 3 fases: inflamatória, proliferativa e de remo- delação. O mecanismo exacto das feridas crónicas permanece ainda por esclarecer. Os avanços recentes da biologia molecular permitiram identificar moléculas que evidenciaram novos mecanismos fisiopatológicos das feridas crónicas, assim como possíveis alvos terapêuticos. Este artigo tem como objectivo uma revisão dos mecanismos envolvidos na cicatrização, pilar fundamental para a compreensão e abordagem de doentes com feridas crónicas, prática corrente em Dermatologia.PALAVRAS-CHAVE – Cicatrização; Factores de Crescimento; Matriz Extra-celular; Integrinas; Feridas Crónicas.
Linear IgA dermatosis, or chronic bullous disease of childhood, is an acquired subepidermic immunobullous disease. This case illustrates a peculiar form of presentation of an uncommon pathology of childhood and emphasizes the importance of dapsone in its treatment, especially in at a time when availability of this drug is limited.KEYWORDS – Immunoglobulin A; Autoimmune Diseases; Skin Diseases, Vesiculobullous; Child; Dapsone.
Tinea capitis is a superficial infection of the scalp caused by dermatophyte fungi, being nowadays the most common fungal infection in children. Griseofulvin remains as the gold standard treatment, however, in many coun- tries, the newer oral antifungal agents (terbinafine, itraconazole and fluconazole) appear to have efficacy and safety profiles similar to those of griseofulvin, allowing treatment courses of shorter duration. This fact associated with the discontinuation of griseofluvin in some European countries has made these drugs increasingly popular in the treatment of this condition. The authors report the case of a girl with tinea capitis caused by Microsporum canis, treated initially with terbinafine and then with itraconazol without any improvement. Just griseofulvin proved to be effective, leading to the cure after 7 weeks o...
