- Existe Associação entre Acufeno e Disfunção Temporomandibular?Publication . Oliveira, M; Barros, C; Caixeirinho, P; Chantre, T; Moreira, I; Proença, F; Sousa, HA coexistência frequente de acufeno e distúrbios da articulação temporomandibular e dos músculos da mastigação (DTM) levou à suposição de que existe uma relação entre as duas condições. O objetivo deste trabalho foi avaliar a prevalência de acufeno em doentes com DTM e os efeitos do tratamento desta sobre o acufeno. Foram incluídos 57 doentes seguidos em consulta de Estomatologia - DTM no ano 2021 e primeiro semestre de 2022. Foi questionada a presença de acufeno e aplicado o questionário Tinnitus Handicap Index (THI). 72% tiveram 1 ou mais episódios de acufeno. 89,5% eram do sexo feminino e verificaram-se 2 picos de incidência na faixa etária entre os 18-30 (21,1%) e os 41-50 anos (24,6%). Em 85,4% dos doentes o acufeno era intermitente e 41,5% grau reduzido. Foi encontrada associação entre a lateralidade do acufeno e da DTM (p<0.001). 67% melhorou o acufeno após terapêutica para DTM (p= 0.0135).
- Pyogenic Liver Abscesses Derived From Dental Disease in an Immunocompetent PatientPublication . Fonseca, L; Caixeirinho, P; Machado, C; Vintém Oliveira, A; Oliveira, M; Pinheiro, JMIntroduction: Pyogenic liver abscess of odontogenic origin is extremely rare. The authors report a case of pyogenic liver abscesses with oral origin caused by Prevotella denticola and Streptococcus anginosus, in an immunocompetent adult. Case Report: A 54-year-old healthy female was presented to our hospital with fever, pain in the right hypochondriac region, constipation, anorexia and history of toothache with gingival swelling. Abdominal X-ray presented showed signs of intestinal obstruction and computed tomography suggested two liver abscesses. The larger one, with 113 mm, was drained under percutaneous ultrasound guidance. Abscess culture isolated Prevotella denticola and Streptococcus anginosus. Under antibiotic therapy, the most common causes for liver abscess were excluded. Dental evaluation found multiple septic foci. Root extractions, dental restorations and periodontal treatments were performed. In this case, abscess culture result is highly suggestive of a dental origin, as species isolated are common oral pathogens. Along with the clinical findings, we are reassured about the original source of infection. Conclusion: This case illustrates the underestimated risk associated with untreated dental diseases. We believe oral infectious foci removal is imperative as primary care. Due to the increase of the cryptogenic liver abscess, we find a systematic dental evaluation is required for the etiological diagnosis of liver abscess.
- Retrospective Study of 114 Free Flaps for Head and Neck Oncological Reconstruction in a Portuguese Tertiary Cancer CenterPublication . Silva, A; Caixeirinho, P; Vilares, M; Semedo, C; Martins, M; Zagalo, C; Casal, DIntroduction: The Portuguese experience in microsurgical reconstruction of the head and neck after oncological surgery is scantly described. The primary aim of this study was to characterize the use of microvascular reconstruction after head and neck tumor resection in a Portuguese tertiary oncological centerMaterial and Methods: The authors retrospectively evaluated 114 microvascular free flap procedures performed for head and neck reconstruction after oncological resection in a department of Head and Neck Surgery of a Portuguese tertiary oncological center. Patients were operated on from January 2012 to May 2018. Data on patient demographic features, tumour characteristics, perioperative complications, postoperative aesthetic and functional results, survival time and time to recurrence were extracted. Results: Most tumours mandating microsurgical reconstruction were mucosal squamous cell carcinomas (85%) and were located in the oral region (95.6%). Around 45% of the patients had a T4a tumour and 30% a T2 tumour. Cervical metastases were present in 45.6% of the cases. The radial forearm flap and the fibular flap were the most commonly used microsurgical reconstructive options (58% and 41%, respectively). More than 80% of patients had no post-operative complications. Partial necrosis of the flap occurred in 6.1% of patients, while total flap necrosis occurred in 3.5% of cases. Aesthetic and functional results were considered at least satisfactory in all patients in which the flaps survived. Discussion: This study is by far the largest series of microsurgical head and neck reconstruction after oncological surgery reported by a single tertiary centre in Portugal. Survival and functional benefits are similar to those reported in other large oncological centres in the world. Conclusion: Microvascular reconstruction seems like a reliable treatment option in head and neck oncological surgery at our institution.
- Síndrome de Stevens-Johnson. Apresentação de Caso ClínicoPublication . Caixeirinho, P; Fonseca, L; Machado, C; Fernandes, AIntrodução: A Síndrome de Stevens-Johnson (SSJ) é uma doença mucocutânea rara e potencialmente fatal, mais frequente no sexo masculino, cuja incidência aumenta com a idade e em determinados grupos de risco. A SSJ e a Necrólise Tóxica Epidérmica (NET) são duas entidades da mesma doença, com severidade diferente. A etiologia não é clara, mas pensa-se que se deva maioritariamente a reacções adversas a fármacos. Caso clínico: Um jovem de 17 anos de idade, sem antecedentes pessoais relevantes, foi observado no Serviço de Urgência por surgimento de lesões maculopapulares, com 3 dias de evolução, dispersas pela face, cavidade oral, tronco e extremidades, com prostração e taquicardia. Foi internado com o diagnóstico de SSJ. Discussão e Conclusões: O SSJ e a NET têm grande morbilidade e considerável mortalidade. O rápido reconhecimento desta identidade, com a remoção do fármaco desencadeador é essencial. A perda da função de barreira da pele, com a consequente alteração da homeostasia, implica muitas vezes a manutenção da terapêutica de suporte em Unidades de Cuidados Intensivos ou de Queimados.
