Butang® response was assessed in 224 newborns who were given the vaccine in the VG region and 250 in the ALT one. Both groups were similar regarding gender, weight, timing interval between doses of the vaccine and maternal characteristics. When comparing Butang® immunogenicity, we verified that the proportion of babies who developed anti-HBs protecting titres after three vaccine doses in the VG region was of 97.8% (IC 95%: 94.8 99.3) with geometric mean titer (GMT) of 427.5 mUI/mL (IC 95%: 344.9 530.0), similar to those who were given in the ALT region (97.6%; IC 95%: 94.8 99.1; GMT: 572.0 mUI/mL; IC 95%: 471.1 694.6), which provides evidence that this place is appropriate for hepatitis B vaccination. Eleven newborns did not respond to Butang®, being six of them vaccinated in the VG region and five in the ALT. The most of them were male, one factor which seems to interfere with hepatitis B vaccine response. We verified an increasing proportion of local reactions and fever according to the number of doses given. In addition, after the third dose the proportion of induration (4.0 vs. 11.4) was higher among babies who were given the vaccine in the ALT region when compared to those who were given in the VG region (p < 0,05). No association was observed concerning maternal anti-HBs titres and newborn vaccine response. The evidences of this study showed that the VG region is a safe and immunogenic site to hepatitis B vaccine administration in newborns. / Este estudo trata-se do primeiro ensaio clínico randomizado controlado, para avaliação da imunogenicidade e reatogenicidade da vacina Butang® em recém-nascidos a termo, que receberam a primeira dose da vacina nas primeiras doze horas de vida, comparando duas regiões de aplicação do imunógeno: ventro glútea (VG) e vasto lateral da coxa (VLC). A resposta à Butang® foi avaliada em 224 RN vacinados na região VG e 250 na VLC. Os dois grupos foram semelhantes quanto ao sexo, peso, intervalo de tempo entre as doses da vacina e características maternas. Ao comparar a imunogenicidade da Butang®, verificou-se que a proporção de crianças que desenvolveu títulos protetores de anti-HBs após a vacinação na região VG foi de 97,8% (IC 95%: 94,8-99,3) com média geométrica dos títulos (GMT) de anti-HBs de 427,5 mUI/mL (IC 95%: 344,9 530,0), sendo semelhante às vacinadas na região VLC (97,6%; IC 95%: 94,8 99,1; GMT: 572,0 mUI/mL; IC 95%: 471,1 694,6), evidenciando, portanto, esses locais como apropriados para a administração do imunógeno. Onze RN não responderam à Butang® com títulos protetores, sendo que cinco foram vacinados na região VG e seis na VLC. A maioria dessas crianças era do sexo masculino, um fator que parece interferir na resposta vacinal contra hepatite B. Em geral, observou-se uma proporção maior de reações locais e febre de acordo com o número de doses recebidas. Além disso, após a terceira dose da vacina, a proporção de enduração foi menor (4,0 vs. 11,4) em crianças vacinadas na região VG do que nas vacinadas na VLC (p < 0,05). Não foi observada qualquer associação entre títulos de anti-HBs maternos e resposta vacinal dos seus conceptos. As evidências deste estudo mostram que a região VG é um local seguro e imunogênico para a administração da vacina contra hepatite B em lactentes.

Lower leg reconstruction after resection of a squamous cell carcinoma on necrobiosis lipoidica with a pedicled fibula and an extended anterolateral thigh flap: a case report

Background Extensive loss of soft tissue and bone due to neoplasia, trauma, or infection in extremities often leads to amputation. Case presentation We present the case of a 72-year-old female patient presenting with an extended cutaneous squamous cell carcinoma of the lower leg, developed on top of necrobiosis lipoidica. After achieving the R0 resection, a 26 × 20-cm soft tissue and 15-cm tibial bone defect resulted. The contralateral leg had been lost due to the same disease 18 years before. We achieved a successful reconstruction of the leg using a pedicled fibula transplantation, an extended anterolateral thigh perforator flap, and an internal fixation with plate and screws. Two years after the original surgery, the patient is relapse-free and mobile, with adequate function of the reconstructed foot. Conclusions Our case presented a unique combination of pedicled fibula transplantation and free extended ALT perforator flap to reconstruct an extensive defect after resection of a rare cSCC on top of NL. In selected cases, the boundaries of limb salvage can be pushed far beyond the current standards of treatment.
