Current Options for the Treatment of Systemic Scleroderma

The epidemiology, pathology, diagnosis, and clinical manifestations of systemic scleroderma (SSc) are described, and therapeutic options are discussed. SSc is a rare condition of unknown etiology that occurs in a subset of scleroderma patients. It is distinguished by involvement of the small arteries, microvessels, and diffuse connective tissue. The degree of internal organ involvement is the main determinant of morbidity and mortality. Management of SSc may entail supportive, palliative, remittive, and immunosuppressive therapies. Supportive therapy involves maintaining the affected extremities at warm temperatures and the use of emollient creams. Results of palliative treatment are mixed. Toxic reactions may be associated with many of these medications. Dermatologic manifestations have been treated with nonsteroidal anti-inflammatory agents, low-dose corticosteroids, dimethyl sulfoxide, and edetate disodium; peripheral and internal-organ vascular obstruction, with alpha-adrenergic blockers, angiotensin-converting-enzyme inhibitors, and calcium-channel blockers. Antacids with alginic acid, histamine H2-receptor antagonists, sucralfate, and cholinergic-acting agents may be used to relieve GI symptoms. Lung infections should be treated promptly with antibiotics. No drug therapy has been successful in reducing the incidence of fatal cardiac arrhythmias or in preventing cardiac fibrosis. Captopril and enalapril are essential in the control of SSc renal crisis. Penicillamine may hold promise as a remittive therapy. The immunosuppressive agents fluorouracil, cyclosporine, and methotrexate, which have shown limited effectiveness in preliminary studies, merit further investigation. No therapeutic agent has yet been shown to alter the course of SSc on a consistent or long-term basis. Toxicity and drug interactions remain a major concern in patient management, and aggressive monitoring is essential.

Untreated Carcinoma of the Breast

Twenty-seven cases of untreated carcinoma of the breast are analysed. Survival rates of 777 plus about 50 cases are collected from various sources, and 757 of these are classified in age groups. A comparison is made with survival rates for 177 treated advanced cases and an evaluation of the results of palliative treatment in a further 201 cases. Factors influencing the mean duration of life are discussed.
