RESUMO

INTRODUCTION: Atypical Teratoid/Rhabdoid Tumor (AT/RT) is a rare aggressive neoplasm that mainly affects the pediatric population with a peak incidence in the first two years of life and a slight male predominance, whereas presentation of this neoplasm in older ages is extremely rare. CASE PRESENTATION: Herein, we present two cases of AT/RT. In the first case, a 9-year-old female presented with diplopia, dizziness, headache, and morning vomiting. CT Scan of the head demonstrated a heterogeneous mass in the left frontal-parietal region with vasogenic edema and midline deviation. In the second case, a 57-year-old female presented with severe generalized headache, numbness, and tingling in the right hand. MRI revealed a lobulated cystic mass in the right occipitotemporal region, with surrounding edema compressing the left lateral ventricle and causing a midline shift to the left, and enlargement of the right lateral ventricle. In both case, histopathological and immunohistochemical examinations revealed the diagnosis of Atypical teratoid/Rhabdoid tumors. CLINICAL DISCUSSION: Microscopic examination demonstrated the proliferation of medium-sized to large cells with abundant eosinophilic cytoplasm, large vesicular eccentric nuclei, and conspicuous nucleoli with areas of necrosis and hemorrhage, thus confirming the diagnosis with adequate immunohistochemical staining. The first patient developed signs of recurrence and passed away six months later, whereas in the second case, the 57-year-old female received radiotherapy for 6 weeks before being put on chemotherapy. CONCLUSION: Despite the challenges facing the diagnosis of this aggressive neoplasm, we managed to present our cases with detailed histopathological and immunohistochemical examinations.

RESUMO

OBJECTIVE: Alcohol privatization efforts have enabled consumers in many states in the United States to purchase alcohol in a variety of off-premise outlets, including grocery stores. This study examines the dual use of outlets to purchase both alcohol and groceries and the extent to which dual use is related to individual income, neighborhood income, and local physical availability of alcohol. METHOD: The East Bay Neighborhoods Study surveyed residents from 72 microecological neighborhoods across six cities in Alameda County, California. Eligible respondents who purchased alcohol in the last year (n = 707) were asked about the off-premise outlet in which they most often purchase alcohol. Purchasing behaviors within this outlet, including purchasing groceries and frequency of visits to the outlet, were assessed. Multilevel logistic regression and negative binomial models assessed outcomes. RESULTS: Seventy-three percent of participants reported dual use of their most used outlet for groceries and alcohol. In adjusted models, dual use of the outlet was not associated with individual income, alcohol use, or neighborhood outlet density but was positively associated with neighborhood income and the number of outlet visits. After adjustment, dual use of the most used outlet was associated with 0.77 more visits per 28 days. CONCLUSIONS: Results suggest that convenience and reduced time costs for purchasing alcohol encourage the dual use of outlets, particularly in high-income neighborhoods. Differences in the dual use of outlets and frequency in outlet use by neighborhood environments highlight the importance of understanding the role of alcohol availability in distinct neighborhood income and outlet-level contexts.

RESUMO

INTRODUCTION: Greater availability of commercial alcohol is associated with increased alcohol use and related public health problems. Greater alcohol outlet density, a marker of alcohol availability, is associated with poorer and predominantly minority neighborhoods. However, poorer populations, African Americans, and Latinxs report using less alcohol compared to Whites and wealthier groups. We consider the role of structural racism in the social ecology of alcohol availability. Specifically we examine racist urban land use practices in the USA which became codified in the 1930s through Federal Home Owner Lending Corporation (HOLC) designations for assigning parcel values, known as "redlining." Redlining demarcated low-density residential zones for wealthy Whites which excluded poor and non-White people as well as certain businesses, including alcohol retailers. We assessed the impacts of historic redlining on present day risks for exposure to retail alcohol availability in urban Northern California. METHODS: For six contiguous and demographically diverse Northern California cities we obtained digital renderings of HOLC maps (1937) which demarcated exclusions of people and businesses for 119 neighborhood areas across four land valuation zones. We then identified the most prevalent HOLC rating for each of 520 current Census block groups in the six cities, including a residual category for areas not rated by HOLC. We geolocated all current (2016) off-premise alcohol sales outlets operating in the six cities (N = 401). We used Bayesian spatial Poisson models to relate current alcohol outlet densities and Census-based estimates of neighborhood characteristics to historic HOLC classifications. RESULTS: Spatial Poisson analyses found far greater contemporary off-premise outlet densities in the lowest-valued HOLC zones than in the highest (median relative rate [RR] 9.6, 95% CI 4.8-22.1). The lowest-valued HOLC zones were also characterized by far higher current percentages of both Black residents (RR 30.4, 95% CI 17.0-54.6) and Hispanic residents (RR 9.7, 95% CI 7.2-12.9). CONCLUSIONS: Present day risks for exposure to retail alcohol availability were delimited by historic exclusionary land use practices. Current inequitable health risks may be founded on racist spatial projects of past decades.

RESUMO

BACKGROUND: Associations between neighborhood crime and alcohol outlets are often theorized as resulting from poor place management. Barriers and supports to place management have been examined for on-premise (bars, restaurants) but not for off-premise alcohol outlets. Few studies have assessed place management issues across a range of off-premise outlet and neighborhood types, and none have included the perspectives of off-premise outlet managers themselves. Combining qualitative and quantitative methods within an ethnographic approach, we investigated barriers and supports to place management across off-premise outlets in a large urban area. METHODS: We unobtrusively assessed outlet operating characteristics including crime prevention strategies at all 403 off-premise outlets in six contiguous California cities; interviewed managers in 40 outlets; and conducted extensive naturalistic observations in 15 of these 40 outlets. We analyzed data for frequencies and thematic content. RESULTS: Small and independently operated off-premise outlets were the most common type of outlet in our study, but demonstrated fewer resources and more challenges to place management compared to large and chain establishments. Security guards were more observed in large and chain outlets. Small and independent outlets were more likely to post signs prohibiting loitering and to enable surveillance of interior spaces. Problems most commonly cited by managers were theft and loitering. Challenges to place management included physical and verbal threats from customers and intoxicated persons, and insufficient law enforcement. Managers evidenced some ability to assert authority over interior, private space, but less so over exterior, public space. CONCLUSIONS: Although tasked with maintaining public health and safety, small and independent store managers reported challenges that are seldom acknowledged in policy or research literature. Managers may provide valuable insights on preventing and reducing neighborhood-level problems associated with off-premise alcohol outlets. Local communities should consider enhancing place management resources for managers of small and independent outlets.
