RESUMO
Abstract Primary retroperitoneal mucinous cystadenocarci nomas (PRMCs) are extremely rare tumors with limited understanding of their pathogenesis and biological be havior. We describe a case of a 50-year-old female patient who underwent surgical treatment. The patient had a history of previous surgeries for mesenteric mucinous cystadenoma, without evidence of recurrence. During routine abdominal ultrasound a new tumor was found. An abdomen magnetic resonance imaging was done and confirmed the presence of a cystic lesion in the right iliac fossa. After discussion in multidisciplinary committee, surgical complete resection of the tumor, along with bilateral adnexectomy, was performed successfully. Histopathological examination revealed a mucinous adenocarcinoma adjacent to a mucinous cystadenoma. Immunohistochemical analysis supported the diagnosis of a primary retroperitoneal lesion. The patient had an uneventful recovery and has remained disease-free du ring the two-year postoperative follow-up. PRMCs are challenging to diagnose preoperatively due to nonspecific symptoms. Surgical excision is the mainstay of treatment. The long-term prognosis and op timal therapeutic strategies require further investigation.
Resumen Los cistoadenocarcinomas mucinosos primarios re troperitoneales (CMPR) son tumores extremadamente raros con una comprensión limitada de su patogénesis y comportamiento biológico. Describimos el caso de una mujer de 50 años some tida a tratamiento quirúrgico. La paciente tenía antece dentes de cirugías previas por cistodenoma mucinoso mesentérico, sin evidencia de recurrencia. Durante una ecografía abdominal de rutina se encontró un nuevo tumor. Se realizó una resonancia magnética abdomen que confirmó la presencia de una lesión quística en la fosa ilíaca derecha. Luego de discutir el caso en el comité multidisci plinario, se realizó con éxito la resección quirúrgica completa del tumor, junto con la anexectomía bilateral. El examen histopatológico reveló un adenocarcinoma mucinoso adyacente a un cistodenoma mucinoso. El análisis inmunohistoquímico apoyó el diagnóstico de lesión primaria retroperitoneal. La paciente tuvo una buena recuperación y permaneció libre de enfermedad durante dos años de seguimiento postoperatorio. Los CMPR son difíciles de diagnosticar debido a que presentan síntomas inespecíficos. La escisión quirúrgica es la base del tratamiento. El pronóstico a largo plazo y las estrategias terapéuticas óptimas requieren más investigación.
RESUMO
Resumen El objetivo de este trabajo fue describir los elementos que configuran la percepción de seguridad escolar en estudiantes de secundaria. Se presenta un estudio cualitativo con enfoque sistémico ecológico. Por medio de un muestreo teórico, se incluyeron a 22 estudiantes, 50 % hombres con 12 a 16 años, quienes participaron en un grupo focal, previo consentimiento informado de los padres. Los datos recabados fueron audio grabados; se transcribieron y analizaron con el método de análisis de contenido por medio del programa Maxqda 18. Se identificaron 4 categorías que configuran la percepción de seguridad escolar: 1) condiciones de la escuela (físicas y organizacionales); 2) elementos relacionados con los maestros; 3) elementos relacionados con los compañeros, y 4) elementos relacionados con los padres. Los hallazgos sugieren que las condiciones físicas y organizacionales mantienen un papel importante en la con figuración del sentido de seguridad escolar. Asimismo, la cercanía y apoyo recibido de actores del contexto (maestros, padres y alumnos) promueve una percepción más positiva de la seguridad.
Abstract The aim of this study was to describe the individual elements that configure the school safety perception in middle school students. We designed a qualitative study, with a systemic and ecological approach. Using a theoretical sampling, we included 22 students, 50% man with an age from 12 to 16 years old, who participated in a focus group, previous informed consent from the parents. The session was videotaped, the data was transcribed and analyzed using content analysis with the program MAXQDA 18. We identified four categories of factors that configure the student's school safety perception: 1) school conditions (physical and organizational); 2) elements related to teachers; 3) elements related to peers; and 4) elements related to parents. The findings suggest that the school´s physical and organizational conditions have an important role in the configuration of the school safety perception. Likewise, the closeness and support received by actors from the school context (teachers, parents and peers) favor a more positive perception of school safety.

BACKGROUND: In Brazil, we are facing an alarming epidemic scenario of Yellow fever (YF), which is reaching the most populous areas of the country in unvaccinated people. Vaccination is the only effective tool to prevent YF. In special situations, such as patients with chronic immune-mediated inflammatory diseases (CIMID), undergoing immunosuppressive therapy, as a higher risk of severe adverse events may occur, assessment of the risk-benefit ratio of the yellow fever vaccine (YFV) should be performed on an individual level. Faced with the scarcity of specific orientation on YFV for this special group of patients, the Brazilian Rheumatology Society (BRS) endorsed a project aiming the development of individualized YFV recommendations for patients with CIMID, guided by questions addressed by both medical professionals and patients, followed an internationally validated methodology (GIN-McMaster Guideline Development). Firstly, a systematic review was carried out and an expert panel formed to take part of the decision process, comprising BRS clinical practitioners, as well as individuals from the Brazilian Dermatology Society (BDS), Brazilian Inflammatory Bowel Diseases Study Group (GEDIIB), and specialists on infectious diseases and vaccination (from Tropical Medicine, Infectious Diseases and Immunizations National Societies); in addition, two representatives of patient groups were included as members of the panel. When the quality of the evidence was low or there was a lack of evidence to determine the recommendations, the decisions were based on the expert opinion panel and a Delphi approach was performed. A recommendation was accepted upon achieving ≥80% agreement among the panel, including the patient representatives. As a result, eight recommendations were developed regarding the safety of YFV in patients with CIMID, considering the immunosuppression degree conferred by the treatment used. It was not possible to establish recommendations on the effectiveness of YFV in these patients as there is no consistent evidence to support these recommendations. CONCLUSION: This paper approaches a real need, assessed by clinicians and patient care groups, to address specific questions on the management of YFV in patients with CIMID living or traveling to YF endemic areas, involving specialists from many areas together with patients, and might have global applicability, contributing to and supporting vaccination practices. We recommended a shared decision-making approach on taking or not the YFV.

STUDY OBJECTIVE: To demonstrate the initial experience in Argentina using the iSpies indocyanine green (ICG) platform in sentinel lymph node mapping in patients with early-stage cervical cancer. DESIGN: Step-by-step demonstration of the technique using a video and pictures (educative video) (Canadian Task Force classification III). SETTING: Laparoscopic and robotic sentinel lymph node mapping using ICG has been shown to be safe and feasible; however, in developing countries, the opportunities to use fluorescent imaging through a minimally invasive approach are very limited, given the cost restrictions of acquiring the near-infrared technology and the fluorescent dyes. INTERVENTION: A 47-year-old woman presented with a stage IB1 squamous cervical cancer. Physical examination revealed a 1.5-cm tumor without evidence of parametrial involvement. Magnetic resonance imaging did not show any evidence of metastatic disease. The patient underwent laparoscopic radical hysterectomy with sentinel lymph node mapping. On laparoscopic exposure of the pelvic spaces, a cervical injection of ICG (1 mL superficial and deep) was administered using a spinal needle at the 3 o'clock and 9 o'clock positions. Sentinel lymph node mapping was then performed using the ICG (Pulsion Medical Systems, Feldkirchen, Germany) and an iSpies near-infrared camera (Karl Storz Endoskope, Tuttlingen, Germany). Bilateral sentinel lymph nodes were detected on the left external iliac artery and in the right obturator space. Both were confirmed ex vivo. The total operative time was 170 minutes. No intraoperative or postoperative complications were reported, and the patient was discharged at 48 hours after surgery. Estimated blood loss was minimal. Sentinel lymph node mapping alone is not the standard of care in our institution, and thus bilateral lymphadenectomy was performed. Ultrastaging is routinely performed when a sentinel lymph node is evaluated. Final pathology revealed a tumor confined to the cervix, with tumor-free margins, and a total of 10 lymph nodes that were negative for any evidence of disease. Disadvantages of this technology compared with the Pinpoint ICG system (Novadaq Technologies; Bonita Springs, FL) is the lack of simultaneous white vision and fluorescence ICG detection, and the to manually change normal vision to infrared vision. An advantage of the Storz iSpies system is its availability in our country, considering that the technology developed by Novadaq is not yet approved in Argentina. CONCLUSION: Although ICG sentinel lymph node mapping is becoming a standard of care [1,2], a lack of ICG dye or laparoscopic near-infrared technologies could be a deterrent to its use in developing countries. A focus on expanding this technology in countries with limited resources would allow patients the opportunity to avoid the morbidity associated with full lymphadenectomy.
RESUMO
Abstract Objective: To evaluate the parameters associated with quality of life in patients with Paget's disease of bone. Methods: Patients with Paget's disease of bone were evaluated with SF-36 and WHOQOL-bref questionnaires. Patients with other diseases that could cause significant impairment of their quality of life were excluded. We searched for correlations between the results and: age, time from diagnosis, type of involvement, pain related to Paget's disease of bone, limitation to daily activities, deformities, bone specific alkaline phosphatase, the extent of involvement and treatment. Results: Fifty patients were included. Results of the SF-36 total score and its domains, physical and mental health, were significantly correlated with bone pain and deformities. Marital status was significantly correlated with the SF-36 total score and Mental Health Domain. BAP levels and disease extension were significantly correlated to SF-36 Physical Health Domain. After multivariate analysis, the only parameters that remained significantly associated with the SF-36 total score and to its Mental Health and Physical Health Domains were pain and marital status.The WHOQOL-bref total score was significantly associated with pain, physical impairment and deformities. WHOQOL-bref Domain 1 (physical) score was significantly associated with marital status, pain and deformities, while Domain 2 (psychological) score was associated with marital status, physical impairment and kind of involvement. After multivariate analysis, the presence of pain, deformities, and marital status were significantly associated with results of the WHOQOL-bref total score and its Domain 1. WHOQOL-bref domain 2 results were significantly predicted by pain and marital status. Conclusion: The main disease-related factor associated with SF-36 results in Paget's disease of bone patients was bone pain, while bone pain and deformities were associated with WHOQOL-bref.
Resumo Objetivo: Avaliar os parâmetros associados à qualidade de vida em pacientes com doença de Paget óssea (DPO). Métodos: Avaliaram-se pacientes com DPO com os questionários SF-36 e WHOQOL-bref. Excluíram-se pacientes com outras doenças que pudessem causar comprometimento significativo da qualidade de vida. Buscou-se por correlações entre os resultados e idade, tempo de diagnóstico, tipo de envolvimento, dor relacionada com a DPO, limitação às atividades diárias, deformidades, fosfatase alcalina específica do osso, extensão do envolvimento e tratamento. Resultados: Incluíram-se 50 pacientes. Os resultados da pontuação total do SF-36 e seus domínios, saúde física e saúde mental, se correlacionaram significativamente com a dor óssea e deformidades. O estado civil se correlacionou significativamente com a pontuação total do SF-36 e com seu domínio saúde mental. Os níveis de BAP e a extensão da doença se correlacionaram significativamente com o domínio saúde física do SF-36. Depois da análise multivariada, os únicos parâmetros que permaneceram significativamente associados à pontuação total do SF-36 e aos seus domínios saúde mental e saúde física foram a dor e o estado civil. A pontuação total do WHOQOL-bref esteve significativamente associada à dor, ao comprometimento físico e a deformidades. O escore do Domínio 1 (físico) do WHOQOL-bref esteve significativamente associado ao estado civil, dor e deformidades, enquanto o Domínio 2 (psicológico) esteve associado ao estado civil, comprometimento físico e tipo de envolvimento. Depois da análise multivariada, a presença de dor, deformidades e estado civil esteve significativamente associada à pontuação total do WHOQOL-bref e à pontuação do seu Domínio 1. Os resultados do WHOQOL-bref 2 foram significativamente preditos pela dor e pelo estado civil. Conclusão: O principal fator associado aos escores do SF-36 foi a dor óssea, enquanto a dor óssea e as deformidades estiveram associadas ao WHOQOL-bref.

The aim of this study was to report a case of two supernumerary teeth in the nasal cavity in a 22-year-old woman who presented pain, rhinorrhea, and inflammation of the nasal mucosa (rhinosinusitis). The computed tomograph scan showed two radiopaque images that were diagnosed as supernumerary nasal teeth. One was unerupted in the floor and the other inverted, and erupted on the floor on the left side of the nasal cavity. They were removed under general anesthesia, one through the palatine approach, and the other directly through the nasal cavity. The patient was followed for a year and there was no sign of recurrence of rhinosinusitis.

Paget's disease of bone (PDB) exhibits a marked geographic variation. In Brazil, the prevalence of PDB is unknown and only a few clinical data are available. The aim is to determine clinical, laboratory, imaging and response to treatment data in a large PDB case series in the city of Florianopolis, Brazil. We have performed a retrospective study based on charts reviews of all patients with PDB followed at the University Hospital of the Federal University of Santa Catarina and at five different private rheumatology outpatient offices in Florianopolis, between 1995 and 2009. One hundred and thirty-four patients with PDB were identified. Mean age at diagnosis was 63.2 ± 10.5 years, 67.2% were women, and 91.1% were Caucasian. Positive family history was reported in only 8.2%. Polyostotic disease was found in 75.0% of the cases, bone pain in 77.9%, and bone deformities in 15.9%. Higher levels of AP were significantly associated with polyostotic disease and skull involvement. Pelvic bones were the most frequently affected (53.7%). Complications included deafness in 8.2%, bone fractures in 3.0%, hydrocephalus in 2.2%, and cauda equina syndrome in 0.7% of the cases. Treatment with zoledronic acid achieved the best response with only 2.9% failing to respond adequately. According to literature data, PDB in South America seems to be characterized by an overall low prevalence, but with localized clusters with higher prevalence. The authors have described a cluster of PDB in Florianopolis, in Southern Brazil. Further properly designed studies are necessary to clarify the PDB epidemiology in South America.

INTRODUÇÃO: O perfil clínico e as estratégias diagnósticas e terapêuticas nos pacientes com embolia pulmonar demonstram a prática clínica na abordagem da doença. Essas informações, escassas nos estudos nacionais, possibilitam melhor conhecimento da embolia pulmonar. MÉTODOS: Estudo multicêntrico de 727 pacientes admitidos em unidades de emergência ou terapia intensiva, com o diagnóstico de embolia pulmonar confirmado por um ou mais dos seguintes exames: arteriografia pulmonar angiotomografia computadorizada helicoidal angioressonância magnética, ecodopplercardiograma, cintilografia pulmonar ou duplex-scan venoso. Dados demográficos, comorbidades, manifestações clínicas e métodos complementares foram analisados. RESULTADOS: A média de idade foi 68 anos, sendo 42 por cento homens. Os fatores de risco mais prevalentes foram: idade > 40 anos, repouso no leito e neoplasia. A dispnéia, taquipnéia, taquicardia, dor torácica, foram as manifestações clínicas mais frequentes. O eletrocardiograma apresentou alterações em 30 por cento, a radiografia de tórax em 45 por cento, o duplex-scan venoso em 69 por cento e o ecodopplercardiograma em 37 por cento. O D-dímero a troponina e a CKMB foram positivos em respectivamente 93, 9 e 8 por cento. Os métodos mais utilizados para o diagnóstico foram: tomografia computadorizada: 47 por cento, duplex-scan venoso: 14 por cento e cintilografia pulmonar: 14 por cento. As formas mais freqüentes de tratamento foram: heparina não fracionada 50 por cento, heparina de baixo peso molecular 30 por cento e trombolítico 12 por cento. A mortalidade intra-hospitalar foi de 19,5 por cento. CONCLUSÕES: Observou-se que a idade > 40 anos, imobilização prolongada e neoplasia foram os fatores de risco de maior prevalência e a dispnéia a apresentação clínica mais freqüente. A angiotomografia computadorizada helicoidal foi o método mais utilizado para o diagnóstico e a heparina não fracionada a principal forma de tratamento.
INTRODUCTION: The clinical profile as well as the therapeutic and diagnostic strategies for patients with pulmonary embolism, describes clinical practice in the approach of the disease. Such information, scarce in national studies, enables a better understanding of pulmonary embolism. METHODS: A multicenter trial included 727 patients with pulmonary embolism who were admitted in emergency or intensive care unit. Diagnostic criteria for inclusion were: 1. Visibility of thrombus in the pulmonary artery at pulmonary arteriography, helical computer tomography, magnetic resonance or echocardiogram. 2. High probability at pulmonary scintigraphy. 3. Venous duplex-scan with thrombus and clinical manifestations of pulmonary embolism. Clinical and complementary exams were analyzed. RESULTS: Mean age was 68 years, 42 percent were male. Most prevalent risk factors were: age>40 years, bed rest and neoplasm. More frequent signs and symptoms were: dyspnea, tachypnea, sinus tachycardia, and chest pain. Changes were observed at electrocardiogram in 30 percent, at chest X-ray in 45 percent, at venous duplex-scan in 67 percent, at transthoracic echocardiogram in 37 percent. . D-dimer, troponin I and CKMB were positive in, respectively, 93, 9 and 8 percent. Most frequently used methods to confirm diagnosis were helical computer tomography and non-fractioned heparin was the treatment most used. In-hospital mortality was 19.5 percent. CONCLUSIONS: It was observed that age>40 years, prolonged rest and neoplasms were the most prevalent risk factors and dyspnea and tachypnea were the more frequent clinical manifestations. Helical computer tomography was the most often used method to confirm diagnosis and non-fractioned heparin was the main form of treatment.

RESUMO
Foram realizados determinações hematológicas (hemograma e contagem de plaquetas) e bioquímicas (glicose, uréia, creatinina, colesterol total, triglicerídeos, ácido úrico, proteínas totais e frações, fosfatase alcalina, transaminases, sódio, potássio, cálcio e magnésio) em camundongos Swiss e ratos Wistar, mantidos no Biotério do Laboratório de Tecnologia Farmacêutica da Universidade Federal da Paraíba. Para a obtenção desses parâmetros foi utlizado sangue obtido pela sangria do plexo braquial. Foram detectadas variações nos valores obtidos entre os animais machos e fêmeas investigados; também ficou evidenciado que existem diferenças nos parâmetros obtidos por outros autores.
Swiss mice and Wistar rats, maintained in the Bioterium of the Laboratory of Pharmaceutics Technology/UFPB, were analysed through haematological (hemogram and platelets) and biochemistry (glucose, urea, creatinine, total cholesterol, triglycerides, uric acid, total proteins and fractions, alkaline phosphatase, transaminases, sodium, potassium, calcium and magnesium) determinations. The blood analysed was obtained from the brachial plexus bloodletting. It was detected that there are variations in the parameters among males and females investigated and so in relation to the values obtained from other searchers.

Esta pesquisa teve como objetivo analisar a incidência das manifestações dermatológicas decorrentes de desnutrição em crianças atendidas no Hospital Universitário Lauro Wanderley (HULW), João Pessoa-PB. Realizou-se um estudo transversal, onde os pacientes portadores de desnutrição primária eram submetidos a exame dermatológico completo e aplicado questionário às mães ou acompanhantes. Do total de crianças que deram entrada no serviço, 52 apresentaram desnutição como causa única da internação; das portadoras de desnutrição grave, 62 (60,19 por cento) tinham marasmo, 31 (30,10 por cento), Kwashiorkor e 10 (9,71 por cento), Kwashiorkor-marasmático. A incidência de lesões cutâneo-mucosas no grupo pertencente ao estudo foi de 7,13 por cento, sendo caracterizadas principalmente por ressecamento de pele, seguida de alterações de cabelos, lesões hipocrômicas e hipercrômicas

Inúmeras áreas da atividade médica e odontológica têm sido beneficiadas pela utilização do raio laser. O objetivo do presente trabalho foi de avaliar ação bactericida do raio laser de bioestimulação em colônias de Streptococcus e Staphylococcus. Os resultados obtidos demonstram a capacidade do raio laser modificar a viabilidade do número de células bacterianas, tanto sobre Streptococcus quanto sobre Staphylococcus. O efeito bactericida do raio laser mostrou-se proporcional ao tempo de irradiação empregado, com resultados mais satisfatórios aos seis e 12 minutos

Embora a disseminaçäo metastática carcinomatosa para estrutura ósseas näo possa ser considerada manifestaçäo rara, principalmente a partir de neoplasias pulmonares, o acometimento patelar associado à invasäo sinovial pode ser estabelecido como fato inusitado. Acompanhamos o caso de paciente idoso do sexo masculino que apresentou, inicialmente, monoartrite de joelho direito. Após dois meses de evoluçäo, foi internado referindo tosse persistente há 30 dias e considerável emagrecimento. A radiografia de tórax, podíamos observar presença de massa para-hilar à direita. A radiografia de joelhos evidenciou lesäo lítica no pólo inferior da patela direita; a cintilografia óssea demonstrou hipercaptaçäo isolada de joelho direito. Foi realizada punçäo sinovial, que obteve líquido hemorrágico. O estudo histológico pulmonar (através de biópsia transbrônquica) foi compatível com diagnóstico de carcinoma epidermóide pouco diferenciado; alteraçöes histológicas similares puderam ser demonstradas na membrana sinovial. A apresentaçäo dessa rara associaçäo, claramente evidenciada, permite que a carcinomatose osteossinovial participe do complexo diagnóstico diferencial das monoartrites crônicas
