OBJECTIVES To review the literature and the diagnosis of conventional histopathological routine and immunohistochemistry of the cases diagnosed with Solid Pseudopapillary Neoplasm of the Pancreas (SPNP). METHODS The review of the literature was done using the Pubmed and solid Google-Scholar databases, through the historical, clinical aspects and diagnostic methods of SPNP. The review of SPNP cases diagnosed in the University Hospital Clementino Fraga Filho was carried out from 1977 to 2018. RESULTS Intratumoral phenotypic heterogeneity of SPNP was evidenced in the cases studied, taking into account macroscopic, microscopic, and immunohistochemical patterns. CONCLUSIONS The results show the importance of the examination of several fragments obtained from different regions of the neoplasia since not all of them present the same molecular alterations.OBJECTIVE To evaluate the prevalence of nonalcoholic fatty liver disease (NAFLD) in patients with HIV/AIDS. METHODS The systematic review included articles indexed in MEDLINE (by PubMed), Web of Science, IBECS, and LILACS. Studies eligible included the year of publication, diagnose criteria of NAFLD and HIV, and were published in English, Portuguese, or Spanish from 2006 to 2018. The exclusion criteria were studies with HIV-infection patients and other liver diseases. Two reviewers were involved in the study and applied the same methodology, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). RESULTS One hundred and sixteen papers were selected, including full articles, editorial letters, and reviews. Twenty-seven articles were excluded because they did meet the inclusion criteria. A total of 89 articles were read, and 13 were considered eligible for this review. Four case series used imaging methods to identify NAFLD, and nine included histology. The prevalence of NAFLD in HIV-patients ranged from 30%-100% and, in nonalcoholic steatohepatitis (NASH), from 20% to 89%. A positive association between dyslipidemia, insulin resistance, and body mass index was observed. There was no agreement between the studies that evaluated the relationship between antiretroviral drugs and NAFLD. CONCLUSION This systematic review showed a high prevalence of NAFLD in HIV-patients, which was associated with metabolic risk factors. The possible association between antiretroviral therapy and NAFLD needs further studies.OBJECTIVE This study aims to investigate the application value of magnetic resonance (MR) hydrography of the inner ear in cochlear implantation. METHODS 146 patients were enrolled. MR hydrography and spiral CT examinations for the intracranial auditory canal were performed before surgery, and all imaging results were statistically analyzed in order to explore the application value of MR hydrography of the inner ear in cochlear implantation. RESULTS 146 patients (292 ears) were examined. Among these patients, 13 were diagnosed with abnormal vestibular aqueducts (20 ears) by MR hydrography, while five were diagnosed with this disease by CT; 15 patients were diagnosed with inner ear malformation (19 ears) by MR hydrography, while 11 were diagnosed by CT (four were misdiagnosed); five patients were diagnosed with internal acoustic canal stenosis (eight ears) by MR hydrography, while two were diagnosed by CT (three were misdiagnosed); and four patients were diagnosed with cochlear fibrosis (five ears) by MR hydrography, while four were diagnosed by CT (four ears). The correct rate of diagnosis was 77.40% (113/146) based on CT, while the rate was 93.84% (137/146) based on MR hydrography. CONCLUSIONS MR hydrography imaging technique can be applied to the preoperative evaluation of cochlear implantation, providing accurate and reliable anatomic information on the inner membranous labyrinth and nerves in the internal acoustic canal and an accurate basis for the diagnosis of cochlear fibrosis and nerve development. learn more This has a guiding significance for the selection of treatment schemes.OBJECTIVES Individuals living with HIV seem to be more prone to changes in the redistribution of body fat, characterized as lipodystrophy, which may occur in conjunction with metabolic diseases. In the present study, such impacts were assessed in adults with and without HIV and associated with the time of virus diagnosis and treatment with antiretroviral. METHODS A cross-sectional study with 123 adults, in which 87 had HIV and 36 without HIV, of both sexes, in outpatient follow-up at the Specialized Care Service (SAE) in Macaé-RJ. The following were made 1) Alteration in body fat distribution, measured by anthropometric parameters and self-reported lipodystrophy; 2) Biochemical profile; 3) Association between HIV diagnosis time and antiretroviral treatment. RESULTS 54.47% (n = 67) males, 45.52% (n = 56) females, mean age 37 years. Of these 87 were people living with HIV, 29% (n = 25) had self-reported lipodystrophy, mean time of virus infection, and antiretroviral treatment (5.80 ± 4.56 and 5.14 ± 3.82 years), respectively. Patients with self-reported lipodystrophy had a greater change in body fat distribution between 3-6 years of HIV diagnosis and a negative cholesterol profile. The antiretroviral treatment time influenced total cholesterol and triglycerides, even for patients without self-reported lipodystrophy, with a further nine years under treatment. CONCLUSION In this study, the negative cholesterol profile was mainly related to antiretroviral treatment time, even for patients without self-reported lipodystrophy, and changes in body fat distribution, measured by anthropometry, was especially associated with time for HIV infection in those with lipodystrophy self-reported.OBJECTIVE To relate disease-free survival and overall survival with type I and type II ovarian cancer and preoperative laboratory parameters biomarkers. METHODS A retrospective study was carried out based on the collection of data from medical records of patients with ovarian tumors. Kaplan-Mayer curves were drawn based on the statistical analysis of the data and were compared using the Log-rank test. RESULTS Disease-free survival in type I ovarian cancer was significantly higher than in type II (p=0.0013), as well as in those with normal levels of CA-125 (p=0.0243) and with a platelet-lymphocyte ratio (PLR) lower than 200 (p=0.0038). The overall survival of patients with type I ovarian cancer was significantly higher than in patients with type II, as well as in patients with normal CA-125 serum levels (p=0.0039) and those with a preoperative fasting glucose of less than 100 mg/dL. CONCLUSION CA-125 levels may predict greater overall and disease-free survival. PLR less then 200 may suggest greater disease-free survival, whereas normal fasting glucose may suggest greater overall survival.
