Paradise lost: Evidence for a devastating metabolic bone disease in an insular Pleistocene deer.

PURPOSE: This communication reports skeletal pathology in a Pleistocene endemic deer from the Mavromouri caves of Crete. MATERIALS: 287 bones and bone fragments from Mavromouri caves are compared to 2986 bones from Liko Cave. METHODS: Bones were evaluated macroscopically, and measurements were made of morphometric characteristics of limb long bones. Representative bone specimens were examined radiographically and histologically. RESULTS: Macroscopic hallmarks were loss of bone mass and increased porosity. The long bones were brittle, some of them having thin cortices, and others reduction of medullary cavities that contain dense Haversian tissue. The flat bones were spongy and fragile. Erosions of the metaphyses and articular surfaces were noted. Histological findings included: sub-periosteal resorption; loss of lamellar bone; enlargement of vascular canals; and remodeling of cortical bone. Two types of fibrous osteodystrophy were recognized in skeletal remains, subostotic and hyperostotic. CONCLUSIONS: The deer of Mavromouri caves were affected by severe metabolic bone disease, likely nutritional secondary hyperparathyroidism. We hypothesize a multifactorial cause, including overgrazing, flora senescence, soil mineral deficiencies, and a prolonged period of climate extremes, degrading the Cretan deer habitat. VALUE: This is the first evidence of a metabolic bone disease causing this level of destructive pathology in an insular fossil deer. LIMITATIONS: The lack of absolute chronometric dates for the site limits potential linking with the prevailing environmental conditions. SUGGESTIONS FOR FURTHER RESEARCH: Investigation of similar skeletal pathologies at other islands or isolated habitats is advised.

[Multiple pathology in a Merowingian individual of a graveyard near Insheim (Rhineland-Pfalz)]. / Multiple Pathologien an einem merowingischen Individuum aus einem Reihengräberfeld bei Insheim (Rheinland-Pfalz).

The following case report describes in detail a 57 years old (+/- 5 years) male individual from a Franconian graveyard in Insheim, Province of Rhineland-Palatinate, dating to between the 6th and 7th century A.D. The individual displays a number of unusual pathologies. The atlas shows a complete aplasia of the posterior arch, probably resulting in a torticollis. The changed static induced a massive spondylar-arthrotic degeneration of the cervical spine on the right-lateral portion. On the fronto-parietal section two fractures are visible which were caused by a sharp and violent force. The area in question measures 7 by 10 cm. It has healed in a dislocated position. The second location displays marks of a 6 cm long sword-cut which did strike the skull obtusely on the left parietal. In addition to the above the skull displays on its right side a great number of small circular hole defects which also appear on ribs, vertebrae, clavicula and the mandible. They present the typical picture of a plasmocytoma. As an expression of a secondary hyperparathyreoidism one can recognize ossifications of soft tissue on the calcaneus, tibia, fibula and patella as well as intravital loss of mandibular dentition. It is quite remarkable that the individual reached a relative old age despite of his numerous and serious physical encroachments due to the apparent and obvious intentions of his aggressive contemporaries to kill him.
