Ingestion of wild and potentially toxic mushrooms is common in the United States and many other parts of the world. US poison centers have been logging cases of mushroom exposure in The National Poison Data System (NPDS) annual publications for over 30 years. This study compiles and analyzes US mushroom exposures as reported by the NPDS from 1999 to 2016. Over the last 18 years, 133 700 cases (7428/year) of mushroom exposure, mostly by ingestion, have been reported. Cases are most frequently unintentional (83%, P < 0.001); cause no or only minor harm (86%, P < 0.001); and in children <6 years old (62%, P < 0.001). Approximately 704 (39/year) exposures have resulted in major harm. Fifty-two (2.9/year) fatalities have been reported, mostly from cyclopeptide (68-89%)-producing mushrooms ingested by older adults unintentionally. The vast majority of reported ingestions resulted in no or minor harm, although some groups of mushroom toxins or irritants, such as cyclopepides, ibotenic acid, and monomethylhydrazine, have been deadly. Misidentification of edible mushroom species appears to be the most common cause and may be preventable through education.

Data on the use of antimicrobial drugs was collected by means of an inquiry to 30 hospitals in Belgium (15 in Dutch sectors and 15 in the French sectors), 21 hospitals in Germany and 20 hospitals in the Netherlands. The use of these drugs was expressed as the number of defined daily doses (DDD) per 100 bed days by the anatomical therapeutical chemical classification system. The total use of antimicrobial agents was significantly (p < 0.001) higher in both parts of Belgium (55.6 and 52.0 DDD per 100 bed days) than in Germany (37.9 DDD) or the Netherlands (34.1 DDD). In particular, amoxicillin-clavulanic acid, the first- and second-generation cephalosporins, aminoglycosides and fluoroquinolones were used more in Belgium than in either of the other countries. At least part of the differences observed in antimicrobial drug use could be explained by differences in written antibiotic policy.

: Mountain climbing epidemiology and current clinical guidelines suggest that a basic mountain medical kit should include items for body substance isolation, materials for immobilization, pain medications, wound care supplies, and medications for gastrointestinal upset and flu-like illness. The medical kits of Colorado mountain climbers varied considerable and often lacked essential items such as medical gloves. This suggests a need for increased guidance. Similar methodology could be used to inform medical kits for other outdoor activities, mountain rescue personnel, and travel to areas with limited formal medical care.

Most mountain climbers had no formal wilderness medicine training and did worse on the medical knowledge assessment than those who did have training. Consistent with previous studies, participants performed poorly on the medical knowledge assessment. As such, ways to improve wilderness medical knowledge among outdoor recreationalists should be sought. The low rate of helmet use on Colorado's technical peaks represents an important area for education and injury prevention.

Mountains are home to numerous organisms known to cause skin disease. Bites, stings, poisons, chemicals, toxins, trauma, and infections all contribute to this end. Numerous plants, animals, fungi, bacteria, viruses, and protozoa are responsible. This paper aims to review skin illness and injury sustained from organisms in the mountains of North America. Other factors such as increased ultraviolet radiation, temperature extremes, and decreasing atmospheric pressure along with human physiologic parameters, which contribute to disease severity, will also be discussed. After reading this review, one should feel more comfortable identifying potentially harmful organisms, as well as diagnosing, treating, and preventing organism-inflicted skin pathology sustained in the high country.

Many organisms of the kingdom Plantae may cause skin reactions when contacted or ingested. Those involved in work and recreation in the great outdoors as well as gardeners and other plant enthusiasts are well aware of this. While Toxicodendron dermatitis from poison ivy, oak, and sumac is the most common cause of allergic contact dermatitis (ACD) in the United States, this is just the tip of the iceberg. Numerous other species of plants are also known causes of ACD, producing a multitude of molecular culprits. Reactions, however, are not limited to type 4 hypersensitivities. Irritant contact dermatitis, phytophotodermatitis or lime disease, and urticarial rashes also occur when certain species come in contact with skin. Furthermore, ingestion of certain plant species may cause rare toxidrome skin eruptions. This paper reviews all of these major known types of phytodermatitis.
