Cutaneous Polyarteritis Nodosa in a Child with Positive Antiphospholipid and P-ANCA

A case of juvenile cutaneous polyarteritis nodosa (cutaneous PAN) is presented. Since early infancy the child underwent attacks of fever and cutaneous rash that occasionally progressed to gangrene and amputations of distal portions of toes and fingers. Although occasional episodes of high blood pressure and persistence of moderate eosinophilia were present, the clinical pattern was mostly restricted to the musculoskeletal system and skin. The authors discuss the definition of the disease and its present therapeutic possibilities, calling attention to a feature not referred in previous reports: the unique co-existence of cutaneous PAN plus antiphospholipid antibodies (aPL) and perinuclear antineutrophil cytoplasmic antibodies (p-ANCA).

Notes on nervios: a disorder of menopause.

The condition of nerves among women in the small Peruvian town of Puente Piedre is described. Both nervios (a symptom) and Nervios (a disorder) describe a woman's difficulty with nerves. In Puente Piedre, the identification of an anxiety condition among women depends only on the women's age. Younger women with anxiety symptoms are diagnosed as nervios, a temporary condition ascribed to a single episode of high blood pressure. Menopausal women with similar symptoms, on the other hand, are thought to have a specific disorder, Nervios. In Puente Piedre, Nervios clearly is a folk illness limited to women of menopausal age.

Sympathetic activity in man after spinal cord injury. Outflow to muscle below the lesion.

Microelectrode recordings were made in peroneal muscle nerve fascicles in 9 patients with traumatic spinal cord lesions at the C5 to T8 level. In 4 patients the lesion was incomplete with some sensibility but no voluntary motor function below the level of the lesion. All patients had increased tendon jerks. EMG was recorded in 5 patients and showed signs of some peripheral denervation. Simultaneous recordings from nerves to skin and to muscle were made in 2 patients and control recordings were made in 19 normal subjects. In the patients, spontaneous neural activity was sparse but after a latency of 0.5-1.1 s strong mechanical and electrical stimuli applied to the skin below the level of the lesion, stimulation of the urinary bladder and deep breaths induced bursts of efferent impulses with a conduction velocity of 0.65 m X s-1. The discharges were often followed by cutaneous vasoconstriction and/or reduction of skin resistance. It is concluded that the neural bursts contained sympathetic impulses of spinal origin. The main differences between patients and normal subjects were spontaneous muscle sympathetic activity was much lower in the patients; no evidence of arterial baroreflex modulation of muscle sympathetic activity was obtained in the patients; and in the patients a given stimulus induced sympathetic reflex discharges which occurred synchronously in muscle and skin nerve branches. Increases of intravesical pressure induced only weak increases of muscle sympathetic activity in the patients but nevertheless marked hypertensive reactions occurred. It is suggested that the excitability of decentralized spinal sympathetic neurons to muscles is usually decreased and that mechanisms other than exaggerated sympathetic outflow must be important for evoking episodes of high blood pressure in patients with spinal cord injuries.
