Epithelial salivary gland tumors in two distant geographical locations, Finland (Helsinki and Oulu) and Israel (Tel Aviv): a 10-year retrospective comparative study of 2,218 cases.

ABSTRACT: Salivary gland tumors (SGTs) of epithelial origin are relatively rare, and worldwide reports show considerable variations in their epidemiology. The aim of this study was to examine, for the first time, the records of SGTs from two very distant geographical locations, Finland (two medical centers) and Israel (one medical center) between 1999 and 2008, based exclusively on the 2005 WHO classification of head and neck tumors, and to compare those data to the other available (single-center) studies that used the same classification. A total of 2,218 benign and malignant tumors diagnosed in the three centers were analyzed. Differences in classification of the tumors were found between the two geographical locations as well as between the two centers from Finland. There was a higher ratio of benign-to-malignant SGTs in the Finnish centers (5.4:1 and 7:1) compared to the Israeli center (2:1), a higher frequency of tumors of minor salivary glands in the Israeli center (34%) than in the Finnish centers (4 and 11%), and a higher frequency of malignant SGTs in the minor salivary glands in Israel (64.5%) than in Finland (10.9 and 27%). The diversity of these multicenter data are compatible with reports from different parts of the world. We conclude that conducting epidemiologic surveys based on the latest WHO classification provides clinicopathologic correlations on SGTs that seem to be characteristic even in small geographical regions.

Project description:The purpose of this pilot cross-national study was to uncover similarities and differences in three areas that might affect the development of community-based programs targeting child maltreatment: behaviors considered to be maltreatment, perceived contributors to maltreatment, and whether the government or neighbors can do anything about maltreatment. Data were obtained from two neighborhood-based, cross-sectional surveys of adult caregivers of minors: one in Cleveland, USA, the other in Tel Aviv, Israel. The sample consisted of a total of 120 caregivers, in each city 20 residing in a low-SES neighborhood, 20 in a medium-SES neighborhood, and 20 in an elevated-SES neighborhood. Participants were asked (a) to provide three examples of behaviors they considered to be child abuse, (b) to rate the degree to which each of 13 factors contribute to child maltreatment, and (c) to rate the degree to which they agreed with a range of attitudes about maltreatment. The same coding scheme was used in both sites. Logistic regression analyses assessed city differences in dichotomous outcomes, while linear regression analyses assessed city differences in ratings of continuous outcomes. Analyses adjusted for individual and neighborhood characteristics, and accounted for residential clustering in neighborhoods. Primary results indicated that residence in Tel Aviv was associated with greater odds of citing emotional/psychological abuse compared to Cleveland residents. Also compared to Cleveland residents, Tel Aviv residents (a) viewed family structure, family values, religion, child-raising knowledge, and personal history of maltreatment as contributing less to maltreatment, (b) were less likely to agree that anyone could abuse a child or that spanking is necessary, and (c) had substantially greater odds of endorsing the government's ability to address child maltreatment. Concerning study implications, this investigation demonstrated the importance of context in shaping constructions of child maltreatment and the need for caution in replicating interventions without due consideration of potential differences in context, policy, and public opinion.
