Hypertension, tachycardia, and reversible cardiomyopathy temporally associated with milnacipran use.

Elevated catecholamine levels are a well-recognized cause of various types of cardiomyopathy. Causes of catecholamine elevation include tumors, toxins, drugs, emotional stress, and sepsis. Milnacipran is a dual and equipotent inhibitor of norepinephrine and serotonin uptake.

Severe refractory fingertip ulcerations in a patient with scleroderma: successful treatment with sildenafil.

Systemic sclerosis (scleroderma) is a multisystem fibrotic disease that commonly manifests with severe Raynaud's phenomenon and slow-healing cutaneous ulcerations. Reduced nitric oxide levels have been proposed to play a role in the pathogenesis of vascular disease in scleroderma, and therefore sildenafil (which increases nitric oxide levels) is an attractive therapeutic prospect. We describe a patient with limited cutaneous systemic sclerosis who presented with severe nonhealing finger ulcerations despite conventional management, who showed marked improvement with oral sildenafil.

Laboratory testing in the rheumatic diseases: a practical review.

Laboratory testing for the rheumatic diseases can allow for rapid diagnosis and appropriate management, while false-positive tests can lead to inappropriate management and unnecessary concern for the patient. An evaluation of laboratory testing for rheumatic illnesses is discussed, including the well-known acute phase proteins, the use of ANA in screening, and the newer antibodies which may potentially allow for an earlier diagnosis. A thorough history and examination are arguably the best screening tests.

Low-dose thalidomide therapy for refractory cutaneous lesions of lupus erythematosus.

Background: Thalidomide is an anti-inflammatory agent and an immunomodulator that inhibits the production of tumor necrosis factor alpha. It has shown promise as a treatment option for the cutaneous manifestations of lupus erythematosus (LE).

Objective: To assess the degree of clinical response per subtype of cutaneous lupus, the duration of therapy before documented clinical improvement, and the incidence of adverse effects, including peripheral neuropathy, with low-dose thalidomide therapy at 100 mg daily in the treatment of refractory cutaneous lesions of LE.
