The Quarterly Review of Biology, 1994
There are three major difficulties encountered by those dealing with the phenomenon of endemism: a semantic problem, the absence of a clear conceptual framework, and an analytical problem. First, the terms endemic and endemism are used in the literature in unclear or contradictory ways.

Squamate areas of endemism in Cuba as determined by parsimony analysis of endemicity
Cladistics, 2018AbstractCuba, the largest island in the Greater Antilles, hosts a high diversity of native squamate reptiles and is characterized by a complex geological history. The island has undergone repeated submergence and emergence, positioned on the dynamic border between the Caribbean and North American tectonic plates.

Management of Hyperparathyroidism in an Endemic Goiter Area
World Journal of Surgery, 1998AbstractIn an endemic goiter area patients with hyperparathyroidism (HPTH) frequently also have thyroid abnormalities. In a retrospective study of 95 patients with HPTH we assessed the diagnostic accuracy of imaging techniques (ultrasonography or radionuclide scanning) for preoperative localization of parathyroid adenomas.

On the Identification of Areas of Endemism
Systematic Biology, 1994Methodological developments in cladis? tic biogeography have mostly focused on converting taxon-area cladograms into area cladograms and on obtaining general area cladograms (Nelson and Platnick, 1981; Wiley, 1988; Page, 1990; Nelson and Ladiges, 1991).

[Endemic zoonosis in Mediterranean area].
Giornale italiano di medicina del lavoro ed ergonomia, 2013The Mediterranean is historically considered an area of high concentration of zoonoses. Mediterranean countries socio-economic features have favoured, over time, the onset of different types of zoonosis. Many of these may affect many occupational categories, first of all farmers, people working in abattoirs and processing products of animal origin. New

Ophthalmia Neonatorum in a Trachoma Endemic Area
Sexually Transmitted Diseases, 1994Chlamydia trachomatis can be directly transmitted by sexual or perinatal contact and indirectly transmitted by flies or fomites. Whether distinct epidemiologic forces among human populations or biologic characteristics of the organism are responsible for the different routes of transmission is uncertain.To determine if ophthalmia neonatorum and ...

Epidemiology of fascioliasis in human endemic areas
Journal of Helminthology, 2005AbstractConsidered a secondary zoonotic disease until the mid-1990s, human fascioliasis is at present emerging or re-emerging in many countries, including increases of prevalence and intensity and geographical expansion. Research in recent years has justified the inclusion of fascioliasis in the list of important human parasitic diseases.
