Periodontal Ehlers-Danlos syndrome Periodontal EDS (pEDS) causes dental problems, particularly inflamed or absent gums and poor tooth development, on top of typical features of cEDS. It is rare but can be inherited from one parent only, as only one faulty gene is needed to develop the condition.
Ribs 1, 2, 11 and 12 can be describes as âatypicalâ â they have features that are not common to all the ribs. Rib 1 is shorter and wider than the other ribs. It only has one facet on its head for articulation with its corresponding vertebrae (there isnât a thoracic vertebrae above it).
Also referred to as reactive lymphocytes, atypical lymphocytes are larger in size with a diameter of more than 30 microns. The large size of the lymphocytes is attributed to antigen stimulation. There are several factors that are responsible for atypical lymphocytes. These atypical lymphocytes are either folded, round, indented or elliptic in shape. They have basophilic cytoplasm and contain several vacuoles.
