Mandibular Involvement in Recurrent Multifocal Osteomyelitis Associated with SAPHO Syndrome.

INTRODUCTION: SAPHO syndrome is defined as the association of a group of rare sterile osteoarticular disorders and inflammatory skin diseases whose etiology, although not yet determined, probably involves genetic, immunological and infectious mechanisms. The recurrent multifocal osteomyelitis, an inflammatory disease, can be associated with this syndrome even as a single event. CASE REPORT: A case of a young female patient, with a definite diagnosis of SAPHO and an inflammatory mandibular atypical disease for which therapeutic options with immunosuppressants were being used, is reported. The adverse evolution of the clinical conditions led to the hypothesis that the patient suffered from associated mandibular odontogenic bacterial osteomyelitis. The extraction of all teeth was recommended. After our evaluation, we recommended a conservative treatment, and after 2 months of treatment with an endovenous antibiotic, the patient showed improvement of clinical and laboratory results. CONCLUSION: Early diagnosis is necessary to avoid successive and unnecessary tooth loss in the treatment of chronic osteomyelitis mandibular.

Deep neck abscesses: study of 101 cases / Abscessos cervicais profundos: estudo de 101 casos

Abstract Introduction: Although the incidence of Deep Cervical Abscess (DCA) has decreased mainly for the availability of antibiotics, this infection still occurs with considerable frequency and can be associated with high morbidity and mortality. Objective: This study aimed to present our clinical-surgical experience with deep neck abscesses. Methods: A retrospective study analyzed 101 patients diagnosed with deep neck abscesses caused by multiple etiologies, assisted at a medical school hospital during 6 years. One hundred one patients were included and 27 (26.7%) were younger than 18 years old (the children group), 74 patients (73.3%) were older than 18 years old (the adults group). The following clinical features were analyzed and compared: age, gender, clinical symptoms, leukocyte count, the affected cervical area, lifestyle habits, antibiotic therapy, comorbidities, etiology, bacterial culture, time of hospitalization, the need of tracheostomy and complications. Results: There was predominance in the male gender (55.5%) and young people (mean age 28.1 years). All of the 51 patients with associated disease comorbidity were adults. The most frequent etiologies were bacterial tonsillitis (31.68%) and odontogenic infections (23.7%). The most common cervical areas affected were the peritonsillar (26.7%), submandibular/mouth floor (22.7%) and parapharyngeal spaces (18.8%). In children group, the site most commonly involved was the peritonsillar space (10 patients, 37%). In adults group, the site most commonly involved was multispace (31 patients, 41.8%). Streptococcus pyogenes (23.3%) was the most common microorganism present. Amoxicillin associated with clavulanate (82.1%) was the more used antibiotic. The main complications of abscesses were septic shock (16.8%), pneumonia (10.8%) and mediastinitis (1.98%). Tracheostomy was necessary in 16.8% of patients. The mortality rate was 1.98%. Conclusion: The clinical features and severity of DCA varied according to different age groups, perhaps due to the location of the infection and a higher incidence of comorbidity in adults. Thus, DCA in adults is more facile to have multispace involvement and lead to complications and seems to be more serious than that in children.

Resumo Introdução: Embora a incidência dos abscessos cervicais profundos (ACP) tenha diminuído, principalmente pela disponibilidade dos antibióticos, essa infecção ainda ocorre com frequência considerável e pode estar associada a alta morbidade e mortalidade. Objetivo: Este estudo teve como objetivo apresentar nossa experiência clínico-cirúrgica com os abcessos cervicais profundos. Método: Um estudo retrospectivo realizado em um hospital universitário analisou 101 pacientes, durante seis anos, diagnosticados com abscessos cervicais profundos causados por múltiplas etiologias. Foram incluídos 101 pacientes, sendo que 27 (26,7%) tinham menos de 18 anos (grupo das crianças) e 74 (73,3%) tinham mais de 18 anos (grupo dos adultos). As seguintes características clínicas foram analisadas e comparadas: idade, sexo, sintomas clínicos, área cervical acometida, hábitos de vida, antibioticoterapia, comorbidades, etiologia, cultura bacteriana, tempo de internação, necessidade de traqueotomia e complicações. Resultados: Houve predominância do sexo masculino (55,5%) e de jovens (idade média de 28,1 anos). Todos os 51 pacientes com comorbidade associada eram adultos. As etiologias mais frequentes foram tonsilite bacteriana (31,68%) e infecções odontogênicas (23,7%). As áreas cervicais acometidas mais comuns foram a peritonsilar (26,7%), submandibular/assoalho da boca (22,7%) e os espaços parafaríngeos (18,8%). No grupo das crianças, o local mais comumente envolvido foi o espaço peritonsilar (10 pacientes, 37%). No grupo dos adultos, houve predomínio de acometimento de múltiplos espaços cervicais (31 pacientes, 41,8%). Streptococcus pyogenes foi o microrganismo presente mais comum (23,3%). A amoxicilina associada ao clavulanato foi o antibiótico mais usado (82,1%). As principais complicações dos abscessos foram choque séptico (16,8%), pneumonia (10,8%) e mediastinite (1,98%). A traqueostomia foi necessária em 16,8% dos pacientes. A taxa de mortalidade foi de 1,98%. Conclusão: As características clínicas e a gravidade dos ACP variam de acordo com as diferentes faixas etárias, possivelmente devido à localização da infecção e à maior incidência de comorbidades em adultos. Assim, o ACP em adultos acomete mais facilmente múltiplos espaços, apresenta mais complicações e parece ser também mais grave do que em crianças.

Extensive Frontoparietal Abscess: Complication of Frontal Sinusitis (Pott's Puffy Tumor).

First described in 1768, the Pott's puffy tumor is a subperiosteal abscess associated with frontal bone osteomyelitis, resulting from trauma or frontal sinusitis. The classic clinical presentation consists of purulent rhinorrhea, fever, headache, and frontal swelling. The diagnosis is confirmed by CT scan and treatment requires intravenous antibiotics, analgesia, and surgical intervention. Early diagnosis and aggressive medical and surgical approach are essential for a good outcome. It rare and the early diagnosis is important; we describe the case of a 14-year-old adolescent with Pott's puffy tumor who was initially treated inadequately, evolving with extensive frontoparietal abscess. The patient underwent surgical treatment with endoscopic endonasal and external approaches combined. Intravenous antibiotics were prescribed for a prolonged time, with good outcome and remission of the complaints.

Expressão de CDX2 e mucinas (MUC1, MUC2, MUC5AC e MUC6) em esôfago de Barrett antes e após fundoplicatura de Nissen / Expression of CDX2 and mucins (MUC1, MUC2, MUC5AC and MUC6) in Barrett's esophagus before and after Nissen fundoplication

INTRODUÇÃO: O esôfago de Barrett (EB) corresponde à substituição do epitélio escamoso por um do tipo intestinal, em resposta ao refluxo crônico nos pacientes com doença do refluxo gastroesofágico (DRGE). É um importante precursor do adenocarcinoma esofágico. A fundoplicatura de Nissen (FN) é uma cirurgia antirrefluxo que visa a reduzir a agressão à mucosa esofágica. Alterações no padrão de expressão imuno-histoquímica de mucinas e de CDX2 no EB antes e depois da FN podem ser úteis na identificação de um padrão de expressão desses marcadores e, eventualmente, na identificação de casos com risco de evolução para malignidade. OBJETIVOS: Avaliar e comparar a imunoexpressão de CDX2 e mucinas no EB de pacientes com DRGE submetidos à FN antes e após a cirurgia. MATERIAIS E MÉTODOS: Estudo retrospectivo de 25 pacientes com diagnóstico de DRGE e EB submetidos à FN, acompanhados por, pelo menos, três anos. Foram feitos análise histológica e estudo imuno-histoquímico das biópsias endoscópicas antes e após a cirurgia, comparando-se a inflamação e a imunoexpressão de MUC1, MUC2, MUC5AC, MUC6 e CDX2. Estimou-se a porcentagem de células com expressão para os marcadores estudados na mucosa de Barrett: 0%-25%, 25%-75% e 75%-100% das células positivas. Foram utilizados os testes de McNemar e Stuart-William e adotou-se o nível de 5% de significância estatística. RESULTADOS E CONCLUSÃO: Não houve diferenças significativas quanto a presença ou intensidade de inflamação, nem da imunoexpressão de mucinas e CDX2 no EB antes e após a FN. O tratamento cirúrgico não influenciou a mudança da expressão dessas glicoproteínas no EB.

INTRODUCTION: Barrett´s esophagus (BE) is characterized by the exchange of esophageal squamous epithelium for intestinal type in response to chronic reflux in patients with gastroesophageal reflux disease (GERD).It is an important precursor of esophageal adenocarcinoma. Nissen fundoplication (NF) is an antireflux surgery which aims to reduce esophageal mucosa inflammation. Changes in the immunohistochemical expression patterns of mucins (MUC1, MUC2, MUC5AC and MUC6) and CDX2 in BE before and after NF may be useful to identify the expression patterns of these markers and, possibly, to detect cases with risks of malignancy. OBJECTIVES: To investigate and compare mucin and CDX2 immunoexpression in BE patients with GERD before and after NF. MATERIAL AND METHODS: This retrospective study comprised 25 patients with GERD and BE who had been submitted to NF. The patients had a 3-year minimum follow up. Histological and immunohistochemical analyses of endoscopic biopsies were performed before and after the surgery, comparing inflammation and MUC1, MUC2, MUC5AC, MUC6 and CDX2 immunoexpression. The percentage of Barrett mucosa cells with expression to the studied markers was estimated at 0%-25%, 25%-75% and 75%-100%. McNemar and Stuart-William tests were used and the significance level of <0.05 was applied. RESULTS AND CONCLUSION: Concerning the presence or the intensity of inflammation and mucin and CDX2 expression in BE, there were no significant differences before and after NF. The surgical procedure did not promote any changes in the expression of these glycoproteins in BE.
