Clinical-epidemiological characterization of patients submitted to hemodialysis according to the national kidney foundation, the kidney disease outcomes quality initiative ­ KDOQI in a hemodialysis reference center in the metropolitan region of São Paulo, Brazil

Introduction: hemodialysis is a treatment that helps in the survival of patients with renal failure, through an established cardiopulmonary bypass to carry out blood filtration, as a result, there is a need for a feasible, lasting and effective vascular access. There are two types of vascular access, arteriovenous fistulas, using autogenous veins or prostheses, and venous catheters. The indications for choosing the type of vascular access are related to the characteristics and restriction of use of each patient.Objective: to analyze the epidemiological, demographic and clinical profile of patients undergoing hemodialysis in two reference services in the metropolitan region of São Paulo, Brazil, and compare the clinical-surgical processes with those defined by the Kidney Guidelines disease Outcomes Quality Initiative (KDOQI).Methods: data were collected in two public hospitals, with patients undergoing hemodialysis, through registration forms and medical records, from August to December 2016. The volunteers were informed about the procedures and objectives of the study and, after agreeing, they signed a consent form. The variables age, gender, weight, height, body mass index, hemodialysis time, types of accesses already used , complications related to the accesses and underlying disease were analyzed. Patients with chronic renal failure undergoing hemodialysis of both genders, with no age restriction, were included. Patients not able to perform one of the techniques, arteriovenous fistula or catheter, were excluded . The collected data were compared with the Kidney guidelines disease Outcomes Quality Initiative (KDOQI).Results: a total of 252 individuals were included, of which 182 are patients undergoing reference hospital treatment in the city of São Bernardo do Campo, SP and 70 patients at the State University Hospital Mário Covas, a State reference in the clinical management of patients undergoing hemodialysis care.Conclusion: chronic kidney disease is highly prevalent with progression to end-stage chronic kidney failure (dialysis). The definition of the epidemiological profile of the population undergoing treatment, as well as the journey of venous accesses for hemodialysis (catheters and fistulas), are fundamental for the multidisciplinary team's learning curve about complications throughout the course of the disease/treatment. Furthermore, the clinical-surgical management of this population is in line with the guidelines of the National Kidney Foundation. The treatment performed in these hemodialysis centers is efficient and in line with what the KDOQI recommends.

Displasia fibrosa recidivante de antro maxilar com invasão de base do crânio / Recurring fibrous dysplasia of anthro maxillary with cranial base invasion

Introdução: A displasia fibrosa é uma lesão óssea com etiologia ainda desconhecida. Caracteriza-se pela incapacidade de maturação óssea. Pode acometer qualquer osso, mas é o acometimento dos ossos craniofaciais o de maior interesse na otorrinolaringologia. A maxila é o osso facial mais afetado, sendo a invasão orbitária um evento incomum. Os sintomas são inespecíficos e, pela baixa suspeição e raridade, o diagnóstico é geralmente tardio. A forma monostótica apresenta crescimento lento e curso assintomático, necessitando apenas de acompanhamento. O tipo poliostótico possui um comportamento progressivo e associa-se a recorrência e complicações. Objetivo: Apresentar dois casos de pacientes com diagnóstico de displasia fibrosa, discutindo a apresentação clínica, os achados radiológicos e o tratamento desta patologia. Relato do Caso: São relatados dois casos de displasia fibrosa que inicialmente apresentaram sintomatologia inespecífica, mas com sinais radiológicos característicos. Foram submetidos a tratamento cirúrgico para ressecção das lesões e evoluíram com recidivas frequentes com acometimento extenso de seios da face, sendo que em um paciente ocorreu invasão de base do crânio havendo necessidade de craniotomia frontal para excisão tumoral. Conclusão: A displasia fibrosa é uma osteopatia incomum. A tomografia é o método de eleição na caracterização da expansão tumoral, auxiliando no planejamento cirúrgico. A estratégica cirúrgica está indicada em lesões sintomáticas, alterações funcionais ou distorções anatômicas. O presente artigo descreve duas raras apresentações de displasia fibrosa recidivante com extenso acometimento de antro maxilar, seios etmoidais e esfenoidais, além de invasão orbitária e base do crânio.

Introduction: Fibrous dysplasia is an osseous lesion with an unknown etiology. It is characterized by the osseous maturation insufficiency. It may affect any bone, but the affection of craniofacial bones is the most critical for otorhinolaryngology. Maxilla is the most affected facial bone and the orbitary invasion is an uncommon event. The symptoms are unspecific and for its low suspicion and uncommonness, the diagnosis is generally late. The monostotic form presents a slow growth and asymptomatic course and needs to be followed up. The polyostotic type has a progressive behavior and is associated to recurrence and complications. Objective: To present two cases of patients with fibrous dysplasia diagnosis and describe the clinical presentation, radiological findings and the treatment of this pathology. Cases Report: Two cases of fibrous dysplasia are reported, which initially presented unspecific symptomatology, but with characteristic radiologic signs. They were submitted to surgical treatment for resection of the lesions and evolved with frequent recurrences with extensive affection of the facial sinuses, one patient had cranial base invasion and frontal craniotomy was needed for tumoral excision. Final Comments: Fibrous dysplasia is an uncommon osteopathy. The tomography is the choice method for characterization of the tumoral expansion, and helps in the surgical planning. The surgical strategy is indicated for symptomatic lesions, functions alterations or anatomic disorders. This article describes two uncommon manifestations of recurrent fibrous dysplasia with an extensive affection of anthro maxillary, ethmoidal and sphenoid sinuses, in addition to orbitary and cranial base invasion.

Prevalence of prognostic factors for cancer of the uterine cervix after radical hysterectomy / Prevalência de fatores prognósticos em câncer de colo uterino após histerectomia radical

CONTEXT AND OBJECTIVE: Cancer of the uterine cervix is still very common in Brazil. It is important to evaluate factors that influence its prognosis. The aim here was to analyze the prevalence of prognostic anatomoclinical factors among patients with carcinoma of the uterine cervix undergoing radical hysterectomy. DESIGN AND SETTING: Cross-sectional study on 301 patients with invasive carcinoma of the uterine cervix who underwent Level III Piver-Rutledge hysterectomy surgery at São Marcos Hospital. METHODS: The following variables were analyzed: age, histological type, degree of differentiation, invasion of lymphatic, vascular and perineural space, lymph node metastasis, distance to nearest margin, tumor invasion depth, vaginal cuff size, largest diameter of the tumor, presence of necrosis and surgical margin involvement. Descriptive statistics, multiple regression analysis, Kaplan-Meier survival curves and the log-rank test were performed. A significance level of 5 percent was used. RESULTS: The mean age was 48.27 years. The following were not important for the prognosis, in relation to survival analysis: degree of differentiation and tumor invasion depth; presence of lymphatic, blood and perineural invasions; distance to nearest margin; and vaginal cuff size. Tumor size (P < 0.036), presence of lymph node metastasis (P < 0.0004), necrosis (P < 0.05) and surgical margin involvement (P < 0.0015) presented impacts on survival. The overall survival with 98 months of follow-up was 88.35 percent. CONCLUSION: The most prevalent prognostic factors were the presence of lymph node metastasis, tumor size and surgical margin involvement.

CONTEXTO E OBJETIVO: O câncer do colo do útero é ainda muito frequente no Brasil, sendo importante avaliar os fatores que influenciam no seu prognóstico. O objetivo é analisar a prevalência dos fatores prognósticos anatomoclínicos em pacientes com carcinoma do colo uterino submetidas a histerectomia radical. TIPO DE ESTUDO E LOCAL: Estudo retrospectivo de 301 pacientes com carcinoma invasivo de colo uterino submetidas a histerectomia radical nível III de Piver-Rutledge no Hospital São Marcos. MÉTODOS: Analisaram-se as variáveis: idade, tipo histológico, grau de diferenciação, invasão do espaço linfático, vascular e perineural, metástase linfonodal, distância da margem mais próxima, profundidade de invasão do tumor, tamanho do manguito vaginal, maior diâmetro do tumor, presença de necrose, comprometimento de margens cirúrgicas. Realizou-se estatística descritiva, análise de regressão múltipla, curva de sobrevida pelo método de Kaplan-Meier e teste log rank. Adotou-se índice de significância de 5 por cento. RESULTADOS: A idade média foi de 48,27 anos. A análise da sobrevida em relação ao grau de diferenciação e profundidade de invasão do tumor, à presença de invasões linfática, sanguínea e perineural, à distância da margem mais próxima e ao tamanho do manguito vaginal não foram importantes no prognóstico. O tamanho do tumor (P < 0,036), presença de metástase linfonodal (P < 0,0004), necrose (P < 0,05) e comprometimento de margens cirúrgicas (P < 0,0015) apresentaram impacto na sobrevida. A sobrevida global com um acompanhamento de 98 meses foi de 88,35 por cento. CONCLUSÃO: Os fatores prognósticos mais prevalentes foram a presença de metástase linfonodal, o tamanho do tumor, a presença de necrose e o comprometimento das margens cirúrgicas.
