We report a case of osteomyelitis and synovitis produced by Mycobacterium marinum in the left index finger of a fisherman. A combination of surgical intervention and antimicrobial therapy with minocycline, rifampin, and ethambutol was efficacious.

OBJECTIVE: To conceptualize community orientation-defined as the generation, dissemination, and use of community health-need intelligence-as a strategic response to environmental pressures, and to test a theoretically justified model of the predictors of community orientation in hospitals. DATA SOURCES: The analysis used data for 4,578 hospitals obtained from the 1994 and 1995 American Hospital Association (AHA) Annual Survey and the 1994 Medicare Hospital Cost Report data sets. Market-level data came from the Area Resource File. STUDY DESIGN: Multiple regression analysis was used to examine the effects of hospital size, dependence on managed care, ownership, network, system and alliance memberships, and level of diffusion of community-orientation practices in the area on the degree of community orientation in hospitals. The model, based on Oliver’s (1991) framework of organizational responsiveness to environmental pressures, controlled for the effects of industry concentration and lagged profitability. PRINCIPAL FINDINGS: Degree of community orientation is significantly related to hospital size; ownership; dependence on managed care; and membership in a network, system, or alliance. It is also significantly related to the diffusion of community-orientation practices among other area hospitals. CONCLUSIONS: Degree of community orientation is influenced by the nature of environmental pressures and by hospital interests. It is higher in hospitals that are large, nonprofit, or members of a network, system, or alliance; in hospitals that are more dependent on managed care; and in hospitals that operate in areas with higher diffusion of community-orientation activities.

Introduction
The study of the biological aspects of Anopheles spp., strengthens the entomological surveillance.
Objective
To determine biological aspects and behavior of adult Anopheles mosquitoes in the urban area of Puerto CarreNo municipality, Vichada, Colombia.
Materials and methods
Wild anophelines were collected landing on humans both indoors and outdoors between 18:00h and 06:00h for 50 min/h during two consecutive nights/month for eight months in the urban area of Puerto CarreNo. The biting rate activity, the natural infection by Plasmodium falciparum and P. vivax VK247 and VK210 using ELISA, and the annual entomological inoculation rate were determined for each species. The members of the Albitarsis complex were determined by amplificacion of the white gene by polymerase chain reaction.
Results
In order of abundance the species found were An. darlingi (n=1,166), An. marajoara sensu stricto (n=152), An. braziliensis (n=59), An. albitarsis F (n=25), An. albitarsis sensu lato (n=16), An. argyritarsis (n=3) and An. oswaldoi sensu lato (n=2). An. darlingi showed two activity peaks between 21:00 to 22:00 and 05:00 to 06:00 hours outdoors and between 21:00 to 22:00 and 04:00 to 05:00 indoors. Natural infection of this species was found with P. vivax VK210 and its annual entomological inoculation rate was 2. Natural infection of An marajoara sensu stricto with P. falciparum was found, with an annual entomological inoculation rate of 5 and a peak biting activity between 18:00 to 19:00 hrs both indoors and outdoors.
Conclusion
Transmission of malaria in the urban area of Puerto CarreNo, Vichada, can occur by An. darlingi and An. marajoara s. s.
