Reflex sympathetic dystrophy of the extremities is a disease with a wide spectrum of clinical manifestations.it is characterized by pain, hyperthermia, and cutaneous changes and has been linked to an abnormality of regional blood flow. The disease is associated with previous injury or trauma including surgery, but also has been found in association with myocardial infarctions and tumors. The final diagnosis can be made only on the basis of the clinical course, which is characterized either by regression without sequel or the appearance of aponeurotic and tendinous retractions including bony sclerosis in the affected region occurring over many months to years. The literature and our own results show that MR imaging has high sensitivity for diagnosing transient osteoporosis of the hip, which is generally thought to be a form of reflex sympathetic dystrophy. Therefore we investigated the usefulness of MR imaging for diagnosing sympathetic dystrophy of the extremities. Twenty-five patients underwent

This paper describes the external morphology of the oro-nasal region of Gorilla, in comparison with Pan. The pattern of furrows involved in certain movements of this region is described. There is a basic pattern of furrows common to man and pongids.

A gross anatomical and microscopical study of the external nose of Tarsius bancanus borneanus demonstrated the typical strepsirrhine shape of the nostrils and an extreme platyrrhine condition. The wide internarial area possesses no sinus hairs. The concepts of strepsirrhinism and haplorrhinism may be used to characterize the different shapes of the nostrils, but they do not have any taxonomical significance.

This is a preliminary study on the comparative microscopic anatomy of the external noses of platyrrhine monkeys. Platyrrhinism is caused by the lateral width of the internarium (Alar cartilages, soft tissue in the sulcus interalaris covered by the integument). The septum nasi, situated caudal to the internarium is not involved in platyrrhinism. Aotus and Alouatta are, according to the definition, truely platyrrhine. The division of the higher primates into Platyrrhina and Catarrhina is justified. The anterior surface of the internarium (sinus hairs) is a sensorial area.
