Pectoral nerve blocks (Pecs I and Pecs II) are superficial thoracic wall blocks which block the pectoral and intercostal nerves. They can be used as analgesia/anesthesia for breast surgery and other procedures/surgeries involving the anterior chest wall (arteriovenous graft creation surgery, minimally invasive cardiac surgery and thoracotomy, etc.). The aim of this study is to evaluate publications in the scientific field of pectoral nerve blocks. ISI Web of Knowledge-Science was used for the analysis. All scientific works published included in the Science Citation Index Expanded (SCI-E) from 1975 to January 27, 2019, were analyzed. A retrospective search was performed using key words "pectoral nerve block," "PECS I," "PECS II," "pecs block," "PECS block,""Pecs I," "Pecs II," "PECS 1," "PECS 2," and "modified pecs I block." We further analyzed these results by the "analyze" function of the software in terms of number of papers for each country, type of documentation, number of publications per year, and name of journals and authors. The number of citations to published works was also calculated by using the citation function of the same software. 72 papers were found related to pectoral nerve block. The biggest contribution was from India (24.28%), and followed by Japan (14.28%), USA (14.28%), Canada (7.14%), Egypt (7.14%), Italy (5.71%), and South Korea (5.71%). The total number of publications increased sharply in years from 2014 (n = 1) to 2018 (n = 28). We have detected that papers on the use of pecs block in breast cancer surgery, which is one of the most common surgical procedure in the world, are few in the literature. With this study, we hope to increase the awareness on this area. We believe that pecs block applications will become widespread with the increasing use of ultrasound in anesthesia and the increase in education in this field. [ABSTRACT FROM AUTHOR]

Purpose - Some police research has used quantitative methods of typology construction in attitudinal data to explore the spatial structure of occupational culture, suggesting distinctions among officer-types may be empirically useful. The purpose of this paper is to suggest scale construction as a complimentary approach, using original data collected from a multi-national sample. Cultural structure is examined here in terms of the spatial relationship among variables rather than respondents. Cultural homogeneity is understood principally as the relative congruence of attitudinal constructs across national groups. Where common constructive dimensions are evident, meaningful analysis of attitudinal valence is then possible. Design/methodology/approach - Data-measuring attitudes in several facets of occupational outlook were collected from police in Canada, India, and Japan. Factor analysis was used to identify latent structures among question items in 11 inventories in the aggregate set and then again in each national sample. Factor solutions were then compared for congruence across the three nations and against the aggregate result. Scores from congruent factors were analyzed using ANCOVA. Findings - The findings suggest an appreciable universality to factor structures in the inventories and samples examined here. Congruence across attitudinal constructs appears to break down in those aspects of occupational outlook that are most personal and most impersonal to the officer. Originality/value - The paper offers a complimentary approach to existing quantitative methods in probing sameness and difference in police culture by focusing upon the constructive meanings of attitudinal measurements as expressive of the conceptual dimensionality of attitudinal space.
