Doppler Ultrasonography of the orbital vessels is a simple non invasive technique for the qualitative determination of velocity and direction of blood flow within the supratrochlear and supraorbital arteries. In temporal arteritis characteristic findings can be obtained with this method. The amplitudes of ultrasonograms are markedly reduced and the waveforms considerably distorted. Sometimes there is a complete absence of velocity signals from the orbital vessels. When the superficial temporal artery is compressed abnormal reactions are almost always elicited, whereas the compression of the homolateral carotid artery yields normal results. In temporal arteritis, the diagnostic value of Doppler ultrasonography of orbital vessels seems about as great as that of Hager ophtalmodynamography.

In cloning human fetal globin cDNA in bacterial plasmids, we obtained a recombinant which contained a fragment of gammg-globin cDNA corresponding to the region from amino acid 99 to the poly A. We determined a sequence of 169 nucleotides which included the complete 3' non-coding region of the gamma-globin mRNA. The codon for amino acid 136 was GCA, indicating that this cloned fragment was derived from the Agamma-globin gene. In conjunction with the surrounding sequences, the GCA codon provides the Agamma-species with a unique CTGCAG hexanucleotide that is recognized by the restriction enzyme Pst I. The 3'-untranslated region of the gamma-globin mRNA consists of 90 nucleotides, and shares little homology with that of the human beta-globin mRNA. As in other mammalian mRNAs, a symmetrical sequence and the hexanucleotide AAUAAA are present.

A close examination of the hands of people depicted in paintings of the Flemish school showed that in five paintings there were figures with hand lesions resembling those of rhematoid arthritis. Although none of the deformities or swellings are indisputable examples of rheumatoid arthritis, they do at least suggest that the painters must have been confronted with rheumatoid-like lesions in their models. In two other paintings there were signs of rheumatic fever and of temporal arteritis. No arthritic lesions were found in the works of painters of the Italian Renaissance, probably because they are less detailed. The finding of rheumatoid deformities in the Flemish paintings does, however, question the general belief that rheumatoid arthritis is a condition that has arisen relatively recently.

Nineteen patients with polymyalgia rheumatica and/or temporal arteritis were classified by degree of clinical and arteriographic abnormality, biopsy grade of arteriosclerosis, and giant cell arteritis (GCA). Temporal arteriograms were very sensitive in detecting abnormal arteries. However, the assumption of some previous studies, that certain angiographic abnormalities are synonymous with GCA, was not supported, since biopsies from distal sites in a Class I and a Class II arteriogram revealed only arteriosclerosis. Class III arteriograms correlated with proximal biopsies of GCA. Immunofluorescent staining was negative in all cases.

A patient with papulonecrotic tuberculid had a pruritic papular eruption associated with constitutional symptoms. The eruption flared whenever the patient received low doses of prednisone to control symptoms of temporal arteritis. A cervical lymph node biopsy specimen demonstrated acid-fast bacilli, and Mycobacterium bovis grew on the cultures. The eruption cleared completely with antituberculous therapy. This case demonstrated the clinicopathologic findings compatible with a diagnosis of papulonecrotic tuberculid. Skepticism regarding the existence of papulonecrotic tuberculid is probably a result of the current decreased prevalence of untreated tuberculosis, and the subsequently increased rarity of this entity.

Sixty-four temporal arteries were studied. 36 were from patients with clinically active temporal arteritis or polymyalgia rheumatica; 22 showed histological changes of temporal arteritis, 12 of which were in an active stage. 28 arteries, none of which showed histological changes, were taken at necropsy or from patients with unrelated disease. Extracellular immunoglobulin and complement deposition was seen in the artery biopsies showing active arteries and in 1 of the 10 biopsies with inactive arteritis. There was no immunoglobulin or complement deposition in the 14 patients with clinically active temporal arteritis and/or polymyalgia rheumatica, but with a normal artery biopsy. Patients with clinically active temporal arteritis were more likely to have a positive biopsy. Our results support the suggestion that the immune deposition is concurrent with an active histologically proven arteritis. Immunofluorescent examination does not appear to be a better diagnostic test than histological examination.

It is important to establish the diagnosis of temporal arteritis because the disease is treatable; treatment may prevent blindness and even death. Temporal arteritis usually occurs in people older than 51 years of age, although very rarely, histologically documented disease occurs in younger people. The onset may be occult, so that there are few findings. A multitude of signs and symptoms may occur such as fever, headaches, malaise, weight loss, anemia, stroke, cranial nerve palsies, polymyalgia rheumatica, aortitis and other large vessel involvement. The eye may suffer from ischemic optic neuropathy (anterior or posterior), central or cilio-retinal arterial occlusion, ophthalmic artery ischemia, or extraocular muscle palsies. An arterial biopsy showing giant cell arteritis establishes the diagnosis. However, a negative biopsy does not rule out the disease because of the occasional presence of skip areas. Arteriography has only rarely yielded a positive temporal artery biopsy when the initial biopsy done elsewhere was negative. As a diagnostic parameter, the erythrocyte sedimentation rate is nonspecific, being elevated in diseases other than temporal arteritis and sometimes being falsely lowered by technical factors. Furthermore, the temporal artery biopsy is occasionally positive despite a normal erythrocyte sedimentation rate. Treatment is aimed at relieving the patient's symptoms and normalizing the erythrocyte sedimentation rate. Because of the wide spectrum of clinical and laboratory finding in temporal arteritis, no one specific treatment regimen with systemic corticosteroids works for all patients. Temporal arteritis is a well known disease of the elderly which ir rarely fatal but results in significant visual morbidity (Hinzpeter & Naumann, 1976; Spencer & Hoyt, 1960). Since Hutchinson's (1890) description, more than a thousand articles have been written on the subject (Cohen & Smith, 1974). Despite this, many unanswered questions and controversies remain concerning the diagnosis, prognosis and treatment of temporal arteritis. My goal is to review these questions and areas of controversy.

A case of polymyalgia rheumatica (PMR) with biopsy-proven giant cell arteritis (GCA) is described in which there were marked abnormalities noted on electromyography (EMG). Spike potentials, positive waves, and fibrillation potentials were seen in the proximal musculature of the upper and lower extremities as well as in the erector spinae muscles. Investigation failed to reveal abnormalities in either creatinine phosphokinase (CPK), aldolase, or muscle obtained at biopsy. The presence of these EMG findings in the PMR-GCA syndrome is unusual. Response to therapy with systemic corticosteroids and normalization of the EMG are documented.

A patient was referred to the neuro-ophthalmology unit with a diagnosis of Foster-Kennedy syndrome; "papilledema" had been noted in the right eye and optic atrophy in the left. Results of radiographic examinations and lumbar puncture had been normal. The considerations and procedures leading to a correct diagnosis of giant cell arteritis are discussed.

A case of giant cell arteritis is reported. The presenting complaint was referable to the vertebral-basilar system. Visual symptoms and signs of vertebral-basilar, carotid, posterior ciliary, and branch central retinal arterial involvement are described. Blindness occurred on steroid therapy. Death resulted from steroid complications. The wide clinical spectrum and management of this condition are discussed.
