Male-to-Female Gender-Affirming Surgery Using Nile Tilapia Fish Skin as a Biocompatible Graft.

STUDY OBJECTIVE: Insufficient penile skin is common during vaginoplasty for male-to-female transition. This issue may be compensated by a scrotal skin flap, with the drawback of hair growth [1]. In recent studies, Nile tilapia skin was successfully used for the surgical management of Mayer-Rokitansky-Küster-Hauser syndrome [2,3] and vaginal stenosis [4,5]. This study aims to describe a novel technique for primary vaginoplasty in male-to-female gender-affirming surgery using Nile tilapia skin as a biocompatible graft to ensure adequate vaginal depth. DESIGN: Stepwise demonstration of the procedure with narrated video footage. SETTING: Transgender health clinic. INTERVENTIONS: A 29-year-old patient with gender dysphoria was referred to our office because of a desire for gender-affirming surgery. A physical examination revealed normal male genitalia with a 14-cm-long penis. Before surgery, approval from the institutional review board and written permission from the patient were obtained. After orchiectomy, penile disassembly, perineal dissection, and urethroplasty were performed, and a hollow Nile tilapia skin mold was prepared and sutured to the distal edge of the remaining penile skin. This structure was inverted, covering the newly created canal. The neocavity was then filled with a handmade inflatable vaginal mold, held in place by sutures in the labia majora. Finally, labiaplasty and clitoroplasty were conducted. After 7 days, the inflatable mold was removed, and the use of progressively larger dilators was initiated. After 3 weeks, a neovagina that was 16 cm long and able to accommodate the width of 2 fingers was detected. At that time, the Nile tilapia skin was completely reabsorbed into the neovaginal mucosa. There were no complications in the early postsurgical period. CONCLUSION: Nile tilapia skin, a safe, low-cost, and easy-to-use biocompatible material, may be an alternative option to scrotal skin grafts for neovaginal augmentation in primary vaginoplasty for male-to-female gender transition. However, further studies are needed to confirm this assertive.

Fissura congênita cervical da linha média / Congenital midline cervical left", "_e": "n

Existe uma deformidade cervical da linha média que tem sido descrita com vários nomes. Embora sua causa embriológica continue sendo controversa, a etiologia mais aceita até hoje é a falha da fusão na linha média dos arcos branquiais distais. A característica principal é uma lesão protuberante na linha média da região anterior do pescoço, entre o mento e a fúrcula esternal. Recomenda-se a ressecção cirúrgica completa da lesão, e a reconstrução do defeito com w-plastia ou zetaplastia. Neste artigo, é relatado o caso de uma paciente de 38 anos, com fissura congênita cervical da linha média. Após exérese da lesão, foi realizada zetaplastia simples, obtendo-se bom resultado tanto estético como funcional. As fissuras congênitas cervicais da linha média são alterações raras na população mundial, porém seu diagnóstico precoce e tratamento cirúrgico adequado são necessários para prevenir alterações no crescimento facial e restrição na extensão do pescoço.

Congenital midline cervical cleft is a deformity known by several names. Although its embryologic origin has not been clearly established, the most widely accepted etiology is impaired midline fusion of the distal branchial arches. The main characteristic of this malformation is a protruding lesion at the midline of the anterior neck, between the chin and the suprasternal notch. Complete surgical resection of the lesion is recommended, with repair of the defect using W-plasty or Z-plasty. This article reports the case of a 38-year-old patient with congenital midline cervical cleft. A simple Z-plasty was carried out after excision of the lesion, and a satisfactory aesthetic and functional result was achieved. Congenital midline cervical cleft is a rare abnormality; however, early diagnosis and appropriate surgical treatment are necessary to avoid changes in the development of the face and limitation of neck extension.

Concomitância de GIST e adenocarcinoma gástrico: revisão e relato de dois casos / Concomitant gastric adenocarcinoma and GIST: review and report of two cases

A presente monografia tem como objetivo realizar revisão bibiográfica sobre concomitância entre adenocarcinoma gástrico e tumor estromal gastrointestinal (GIST). Foram analisados 106 prontuários de pacientes submetidos à gastrectomia pelos serviços de cirurgia geral I e II num período de cinco anos (2003-2007) no Hospital Universitário Antonio Pedro da cidade de Niterói, Brasil. Os dados obtidos dos prontuários foram confirmados no registro de patologia do mesmo hospital e posteriormente foram relatados dois casos de concomitância entre as duas patologias. Um achado incomum na prática médica.
