Successful treatment of idiopathic mast cell activation syndrome with low-dose Omalizumab.

Objectives: Idiopathic mast cell disorders, a recently defined and recognised syndrome in clinical practice, are similar to the previously termed non-clonal mast cell disorder. Patients with idiopathic mast cell activation syndrome (MCAS) suffer all the classical signs of mast cell activation but do not have evidence of mast cell clonality. Furthermore, treatment of these patients can be limited and burdensome in those with refractory symptoms.

First case of Chlorella wound infection in a human in Australia.

A 30-year-old man developed an infected knee wound 2 days after jumping his bicycle into a freshwater dam. He required repeated debridement and tissue grew bright green colonies typical of the alga Chlorella plus Aeromonas hydrophila. This, and one previously reported case, responded to surgical debridement and careful wound management.

Acetylation phenotype is not associated with breast cancer.

In the present study, we have measured acetylation phenotype in 45 patients who had undergone surgical resection of a primary adenocarcinoma of the breast and in 48 patients or volunteer subjects with no breast disease. Phenotype was determined by measuring the ratio of N-acetylsulfamethazine to N-acetylsulfamethazine plus sulfamethazine in plasma 6 h after a p.o.
