Multiple meningeal diverticula and cysts associated with duplications of the sheaths of spinal nerve posterior roots.

Multiple diverticula and cysts of the meninges were found during an anatomical dissection. They were associated with duplications of sheaths of the posterior roots of the spinal nerves. The diverticula and cysts appeared as simple flaccid corrugated dilatations of the sheaths, as ampullary expansions, as pediculated cysts, or as saccular dilatations of different sizes and locations. The duplication of the sheaths affected posterior roots of the thoracic nerves only. Some variations of the sheaths described in the literature are discussed. The possibility is considered that both conditions result from the same pathological factors in the embryo.

Pathology of bedouin skeletal remains from two sites in Israel.

Frequency of pathology and of some anomalies in skeletons of Bedouin living about 200 BP, uncovered in the Israeli Negev, is considered in relation to particular bone, sex, age-group, and kinds of defects. The environment of the Bedouin in relation to his "health-status" is noted. Two-thirds of the skeletons had one or more different bones with defects. Incidence of crania with defects was: males, 26%, females, 18%; the highest incidence occurred at age 35-49. Alveolar abscesses occurred in 28% of maxillae, 9% of mandibles. Of the long bones, the tibia was most frequently affected (15%): swelling of the shaft, relatively common, was apparently caused by bejel, a non-venereal form of syphulis, similar to yaws, endemic to the Bedouin. Forty-eight percent had defective vertebrae, usually an arthritic manifestation of one kind or another; half of this group had defects in more than one region of the spine. Defects also occurred relatively frequenly in the innominata, sacrum, scapula, and clavicle, mostly arthritic lesios except in the sacrum in which the percentage with sacral hiatus was high. Average age at death was, males, 43 years, females, 33 years (adults only), and 28 years for all ages.

Saphenous nerve entrapment simulating vascular disorder.

Saphenous nerve entrapment may cause a painful syndrome simulating vascular disorder of the leg. The anatomical relationship of the saphenous nerve is described to explain the pathogenesis of the syndrome. The clinical features, diagnosis, and results of treatment of 32 patients are reported. The differential diagnosis of the syndrome is discussed. It is concluded that entrapment of the saphenous nerve should be considered when other known syndromes are unable to explain the symptomatology.
