RESUMO
OBJECTIVE: To investigate the epidemic characteristics of human cutaneous anthrax (CA) in China, detect the spatiotemporal clusters at the county level for preemptive public health interventions, and evaluate the differences in the epidemiological characteristics within and outside clusters. METHODS: CA cases reported during 2005-2012 from the national surveillance system were evaluated at the county level using space-time scan statistic. Comparative analysis of the epidemic characteristics within and outside identified clusters was performed using using the χ2 test or Kruskal-Wallis test. RESULTS: The group of 30-39 years had the highest incidence of CA, and the fatality rate increased with age, with persons ≥70 years showing a fatality rate of 4.04%. Seasonality analysis showed that most of CA cases occurred between May/June and September/October of each year. The primary spatiotemporal cluster contained 19 counties from June 2006 to May 2010, and it was mainly located straddling the borders of Sichuan, Gansu, and Qinghai provinces. In these high-risk areas, CA cases were predominantly found among younger, local, males, shepherds, who were living on agriculture and stockbreeding and characterized with high morbidity, low mortality and a shorter period from illness onset to diagnosis. CONCLUSION: CA was geographically and persistently clustered in the Southwestern China during 2005-2012, with notable differences in the epidemic characteristics within and outside spatiotemporal clusters; this demonstrates the necessity for CA interventions such as enhanced surveillance, health education, mandatory and standard decontamination or disinfection procedures to be geographically targeted to the areas identified in this study.

From the first reliable descriptions of acne in the early 19th century, dermatologists recognized it as a disease of the pilosebaceous follicle. Until the middle of the 20th century, they hypothesized that seborrhoea, follicular keratosis and microorganisms could be individually responsible for the acne lesions. Inflammation was only regarded as the final and inescapable step of the acne process. Although the importance of these factors has been reevaluated, recent works still regarded them as mandatory. In the 1970s, the onset of isotretinoin dramatically improved acne management. It also provided great opportunities for a better understanding of the pathogenic factors of acne. This study analyzes their genesis and development from the seminal contributions until recent advances.

Approximately 10% of the island population of Satowan (population, 650 persons), a small, remote coral island in the central Pacific, suffers from an acquired, chronic, disfiguring skin condition known locally as "spam." This skin disease has affected the island population since shortly after World War II. An investigation in 2007 revealed that this skin disease is caused by a nontuberculous mycobacterial infection closely related to Mycobacterium marinum. This article reviews the fascinating history of this skin disease on Satowan, its distinctive clinical presentation, and recommendations for diagnosis and treatment of clinically similar skin lesions in Pacific Islanders.

BACKGROUND: Anthrax is an often fatal bacterial infection, occurring in cutaneous, inhalational, gastrointestinal, and meningeal forms. Evaluation of anthrax treatment from ancient history may help healthcare providers to handle this serious disease more efficiently. OBJECTIVE: To evaluate the biblical descriptions of anthrax, focusing on its therapy in ancient times. STUDY SELECTION: All biblical texts associated with anthrax were examined and passages relating to this disease were studied closely. DATA SYNTHESIS: Biblical passages such as: "Take a cluster of figs. And they took and laid it on the boil [anthrax], and he recovered," and "Let them take a cluster of figs, and lay it upon the boil [anthrax], and he shall recover," convincingly indicate that figs have healing properties in cutaneous anthrax lesions. CONCLUSIONS: On the basis of this study, the National Institutes of Health together with the pharmaceutical industry may consider to work on isolation of compounds from fig plants to develop products against cutaneous and possibly other forms of anthrax once screening tests are completed.
