Acute intermittent porphyria is the most frequent of the acute hepatic porphyrias. This is caused by mutations of autosomal dominant inheritance in the HMBS gene, which generate a deficiency of the enzyme porphobilinogen deaminase in the biosynthetic pathway of the heme group. It is characterized by potentially life-threatening neurovisceral symptoms, including abdominal pain, vomiting, constipation, muscle weakness and seizures. Such attacks are triggered by medications, fasting, alcohol, hormonal changes, stress, among others. Its treatment includes high carbohydrate loads, intravenous hemin, and medical support. Some patients who develop recurrent acute attacks may require prophylactic hemin or gonadotropin-releasing hormone analogs. Liver transplantation is indicated for patients refractory to those treatments. Chronic complications of the disease include hepatocellular carcinoma, hypertension, chronic kidney disease, and chronic pain. [ABSTRACT FROM AUTHOR]

We studied the local knowledge and preferences of 160 inhabitants of La Vieja river basin on 60 native species of trees, shrubs and palms. During two years, we made extensive interviews based on photographs of all species, asked the people to identify the plants and asked questions on the habitat, growth rate and uses of each species. We also asked the interviewees if they would be willing to grow these species on their farms, where they would do so and what kind of external support they would need. Most interviewees recognized less than half of the species. The collective judgment of the relative growth rates is accurate and useful to guide restoration decisions. A high proportion of the people would be willing to plant many of species if they had access to seedlings. The preferred species for planting were Inga densiflora, I. edulis, Erythrina poeppigiana, Tecoma stans, Aniba sp. Nectandra turbacensis, Ocotea macropoda, O. helicterifolia, Senna spectabilis and Cedrela odorata. Grazing and riparian areas were the preferred places to plant native trees. [ABSTRACT FROM AUTHOR]
