Dermatology surgery

Las víctimas de ataques con productos químicos y subsecuentes quemaduras presentan secuelas psicológicas y físicas dependiendo del área afectada. La alopecia cicatricial, en particular, es de difícil tratamiento y todo lo que se le ofrezca al paciente como medida terapéutica que mejore su apariencia, elevará su autoestima. Se presenta el caso de una paciente con secuelas de alopecia cicatricial por quemadura química en el cuero cabelludo, a quien se le trasplantó pelo con la técnica de miniinjertos con sacabocado, con mejoría clínica importante.

Background: Anxiety can complicate any outpatient procedure by causing elevation in blood pressure and heart rate with resultant increase in intraoperative and postoperative bleeding. Anxiety may also reduce patient satisfaction with the surgical experience. Midazolam is an efficacious short-acting benzodiazepine with an excellent safety record. However, little experience is documented on the use of midazolam in outpatient dermatologic surgery. Objective: To establish the safety and efficacy of oral midazolam in healthy patients undergoing Mohs micrographic surgery. Methods: Patients undergoing outpatient Mohs surgery were randomized in a double-blind, placebo-controlled study of single-dose midazolam for efficacy and safety in producing anxiolysis of short duration. A subpopulation of patients was evaluated prospectively in a nonrandomized arm of the study. Data on vital signs, anxiety, adverse events, and overall satisfaction were collected and compared using analysis of covariance model. Results: Forty-four patients were randomized and 31 patients were enrolled in the prospective arm. Socioeconomic and surgical characteristics were similar among the groups. At 60 minutes, there was a clinically and statistically significant reduction in anxiety and alertness in both randomized and prospective arms. There were no major adverse events. Patients in all 3 groups were equally satisfied with their experience. Limitations: Few patients with high perioperative anxiety were willing to participate in a randomized controlled trial of anxiolytic medication. Conclusions: Midazolam is safe and efficacious in perioperative anxiolysis for healthy patients undergoing outpatient Mohs micrographic surgery. Midazolam offers the benefits of amnesia, reduced alertness, and reduced blood pressure with no clinically significant adverse effects. (J Am Acad Dermatol 2011;64:310-22.)

Karsinoma sel basal (KSB) tercatat sebanyak 75% dari semua kanker kulit. Data epidemiologis dunia menunjukkan peningkatan insidensi KSB 3-10% dalam setahun, hal ini diduga berkaitan dengan penipisan lapisan ozon (2% dalam 20 tahun terakhir) dan perubahan gaya hidup. Karsinoma sel basal (KSB) dapat menyebabkan cacat kosmetik maupun cacat fungsional sehingga diperlukan diagnosis dini dan penatalaksanaan yang tepat. Seorang perempuan 72 tahun, dengan keluhan benjolan yang semakin membesar kemudian menjadi borok di pelipis kiri sejak satu tahun. Riwayat sering terpajan sinar matahari. Pada pemeriksaan fisik ditemukan ulkus dengan diameter 3 cm dan krusta. Temuan histopatologik menunjukkan sel ganas dengan inti hiperkromatik dan tepi palisade. Penatalaksanaan dengan bedah eksisi, flap rotasi dan skin graft. KSB jarang bermetastasis, namun dapat mendestruksi jaringan di dekatnya. Studi epidemiologi memberikan fakta bahwa patogenesis KSB dapat terjadi melalui efek imunologik dan karsinogenik. Gambaran histopatologik penting untuk menentukan varian KSB. Prognosis quo ad vitam bonam, ad sanam dubia ad bonam, ad kosmetikam dubia ad bonam.
