Thalidomide as treatment of refractory aphthous ulceration related to human immunodeficiency virus infection.

In recent years, thalidomide has been used for the treatment of a variety of ulcerative and immunologic conditions. Several previous reports have suggested that thalidomide therapy is beneficial for patients with aphthous ulceration related to human immunodeficiency virus (HIV) infection. We describe the use of thalidomide in 20 HIV-infected patients with oropharyngeal, esophageal, and rectal ulceration. Nineteen patients had a dramatic response to thalidomide therapy, with both subjective and objective abatement in the signs and symptoms of their ulcerative disease. The standard treatment course was 200 mg of thalidomide for 14 days (the drug was administered at night). Four patients required additional courses of treatment because symptoms recurred after thalidomide therapy was stopped. Side effects due to thalidomide included rash (5 patients), peripheral neuropathy (1 patient), and excessive fatigue (1 patient). There did not appear to be any adverse immunologic effects in thalidomide-treated patients. The mechanism of the effect of thalidomide is uncertain, although recent studies have suggested that thalidomide selectively inhibits the production of tumor necrosis factor alpha.

Severe botulism after eating home-preserved asparagus.

OBJECTIVE: To present a case of adult botulism acquired in Queensland. CLINICAL FEATURES: After eating home-preserved asparagus, a 33-year-old man presented with internal and external ophthalmoplegia, bilateral facial nerve palsies, and descending muscle weakness culminating in a sudden respiratory arrest. Electrophysiological testing demonstrated normal nerve conduction velocities and an incremental response of evoked motor potentials on repetitive stimulation, confirming the clinical diagnosis of botulism. INTERVENTION AND OUTCOME: Treatment with trivalent antitoxin, oral treatment with vancomycin and supportive mechanical ventilation for four weeks resulted in complete clinical recovery. Plasmapheresis was also used but its contribution to the patient's improvement is dubious. CONCLUSIONS: Although botulism is rare in Australia, clinicians should be aware of the clinical presentation and the rapidity of confirmation of the diagnosis by electrophysiological testing. Patients should be nursed in an intensive care setting. Regular testing of vital capacity should be performed to determine the need for mechanical ventilation.
