Abstract BACKGROUND Medulloblastoma (MB), the most malignant brain tumor of childhood has survival outcomes exceeding 80% for standard risk and 60% for high risk patients in high-income countries (HIC). These results have not been replicated in low-to-middle income countries (LMIC), where 80% of children with cancer live. Brazil is an upper-middle income country according to World Bank, with features of LMIC and HIC. METHODS We conducted a retrospective review of 126 children (0–18 years) diagnosed with MB from 1997 to 2016 at INCA. Data on patients, disease characteristics and treatment information were retrieved from the charts and summarized descriptively; overall survival (OS) and event-free survival (EFS) were calculated using the Kaplan-Meier Method. RESULTS The male/female ratio was 1.42 and the median age at diagnosis was 7.9 years. Headache (79%) and nausea/vomiting (75%) were the most common presenting symptoms. The median time from onset of symptoms to surgery was 50 days. The OS for standard-risk patients was 69% and 53% for high-risk patients. Patients initiating radiation therapy within 42 days after surgery (70.6% versus 59.6% p=0.016) experienced better OS. Forty-five patients (35%) had metastatic disease at admission. Lower maternal education correlated with lower OS (71.3% versus 49% p=0.025). Patients who lived >40km from INCA fared better (OS= 68.2% versus 51.1% p=0.032). Almost 20% of families lived below the Brazilian minimum wage. CONCLUSIONS These findings suggest that socioeconomic factors, education, early diagnosis and continuous data collection, besides oncological treatment must be adressed to improve the survival of children with MB.

PURPOSE: To evaluate potential risk factors for the development of multiple sclerosis in Brazilian patients. METHOD: A case control study was carried out in 81 patients enrolled at the Department of Neurology of the Hospital da Lagoa in Rio de Janeiro, and 81 paired controls. A standardized questionnaire on demographic, social and cultural variables, and medical and family history was used. Statistical analysis was performed using descriptive statistics and conditional logistic regression models with the SPSS for Windows software program. RESULTS: Having standard vaccinations (vaccinations specified by the Brazilian government) (OR=16.2; 95% CI=2.3-115.2), smoking (OR=7.6; 95% CI=2.1-28.2), being single (OR=4.7; 95% CI=1.4-15.6) and eating animal brain (OR=3.4; 95% CI=1.2-9.8) increased the risk of developing MS. CONCLUSIONS: RESULTS of this study may contribute towards better awareness of the epidemiological characteristics of Brazilian patients with multiple sclerosis.

Despite interest in the origins of syphilis, paleopathological analysis has not provided answers, and paleogenetic diagnosis remains a challenge. Even venereal syphilis has low infectivity which means there are few circulating bacteria for most of the individual’s life. Human remains recovered from the Nossa Senhora do Carmo Church (17th to 19th centuries) and the Praça XV Cemetery (18th to 19th centuries), Rio de Janeiro, Brazil, were subjected toTreponemapaleogenetic analysis. Historical data point to endemic treponemal infections in the city, including venereal syphilis. Based on the physiopathology ofTreponema palliduminfection, 25 samples, mostly from skull remains of young adults, with no visible paleopathological evidence of treponematoses, were analyzed. PCR with three molecular targets,tpp47,polA, andtpp15, were applied. Ancient DNAtpp15 sequences were recovered from two young adults from each archaeological site and revealed the polymorphism that characterizesT. p.subsp.pallidumin a female up to 18 years old, suggesting a probable case of syphilis infection. The results indicated that the epidemiological context and the physiopathology of the disease should be considered in syphilis paleogenetic detection. The findings ofTreponemasp. aDNA are consistent with historical documents that describe venereal syphilis and yaws as endemic diseases in Rio de Janeiro. Data on the epidemiological characteristics of the disease and its pathophysiology offer new perspectives in paleopathology.

BACKGROUND: Medulloblastoma (MB), the most malignant brain tumor of childhood has survival outcomes exceeding 80% for standard risk and 60% for high risk patients in high-income countries (HIC). These results have not been replicated in low-to-middle income countries (LMIC), where 80% of children with cancer live. METHODS: Retrospective review of 114 children (3-18 years) diagnosed with MB from 1997 to 2016 at INCA. Data on patients, disease characteristics and treatment information were retrieved from the charts and summarized descriptively. Overall survival (OS) and event-free survival (EFS) were calculated using the Kaplan-Meier Method. RESULTS: The male/female ratio was 1.32 and the median age at diagnosis was 8.2 years. Headache (83%) and nausea/vomiting (78%) were the most common presenting symptoms. Overall survival (5y) was 59,1% and EFS (5y) was 58,4%. The OS for standard-risk patients was 69% and 53% for high-risk patients. Forty-five patients (35%) had metastatic disease at admission. Lower maternal education correlated with lower OS (71.3% versus 49% p=0.25). Patients who lived >40km from INCA fared better (OS= 68.2% versus 51.1% p=0.032). Almost 20% of families lived below the Brazilian minimum wage. CONCLUSIONS: The epidemiological characteristics of this series possibly explain the differences in survival that medulloblastoma patients have in Brazil. Issues related to limited health care resources, poverty, delayed diagnosis, treatment abandonment, and malnutrition are reflected in inferior survival outcomes when compared to high-income countries. Despite the difficulties encountered in an upper-middle income country, it was possible to deliver treatment with good results.

The aim of this case series was to describe the clinical, laboratory and epidemiological characteristics and the presentation of bacillary angiomatosis cases (and/or parenchymal bacillary peliosis) that were identified in five public hospitals of Rio de Janeiro state between 1990 and 1997; these cases were compared with those previously described in the medical literature. Thirteen case-patients were enrolled in the study; the median age was 39 years and all patients were male. All patients were human immunodeficiency virus type 1 (HIV-1) infected and they had previous or concomitant HIV-associated opportunistic infections or malignancies diagnosed at the time bacillary angiomatosis was diagnosed. Median T4 helper lymphocyte counts of patients was 96 cells per mm³. Cutaneous involvement was the most common clinical manifestation of bacillary angiomatosis in this study. Clinical remission following appropriate treatment was more common in our case series than that reported in the medical literature, while the incidence of relapse was similar. The frequency of bacillary angiomatosis in HIV patients calculated from two of the hospitals included in our study was 1.42 cases per 1000 patients, similar to the frequencies reported in the medical literature. Bacillary angiomatosis is an unusual opportunistic pathogen in our setting.

e19083 Background: IBC is one of the most aggressive types of breast cancer, accounting for only 1-4% of all breast cancer cases while causing 8-10% of breast cancer related deaths. Previous studies have demonstrated that IBC has distinct epidemiological characteristics, but the prevalence of IBC particularly in Native Hawaiian (NH) and Pacific Islander (PI) populations, and the socioeconomic disparities related to survival outcomes, are not fully understood. Our primary objective was to determine the frequency at which NH and PI breast cancer patients are diagnosed with IBC, and the association between socioeconomic status and overall survival (OS). Methods: Patients with newly-diagnosed primary invasive breast cancer were identified from January 1, 2000 through December 31, 2018 using Queen’s Medical Center Tumor Registry. Clinical T4d was used to differentiate IBC and non-IBC. OS was defined as the time from diagnosis to death or last follow-up. Patients who were alive at the date of last follow-up were censored. Univariate and multivariate cox proportional hazard models were used to assess the effects of variables of interest on OS. Results: A total of 3,715 patients were included in analysis. There were 98 (2.6%) patients with IBC and 3,617 (97.4%) with non-IBC. Proportion of IBC relative to non-IBC was significantly higher in PI (9.0%) than in White (W) (2.7%) (P < 0.001). Proportion of IBC was higher in NH (4.7%) than W but the difference was not statistically significant (P = 0.08). In multivariate analysis among the non-IBC group, OS was significantly shorter for both PI and NH than W (HR 1.72, [95%CI, 1.13-2.6]; P = 0.01, HR 1.48 [95% CI, 1.14-1.93]; P = 0.003, respectively). There were no significant racial differences seen in OS among IBC patients. Being under or uninsured was also significantly associated with short OS outcomes among patients with non-IBC but not those with IBC. Conclusions: PI have a significantly high proportion of IBC relative to non-IBC. Race and insurance status were not associated with OS in IBC although they were significantly associated with short OS in non-IBC. This result suggests that in IBC, the potential effect of racial disparity on OS is negated by the aggressive and insidious nature of the cancer. The effect of a relatively small sample size cannot be excluded, and further study in a larger population is warranted.
