Orofacial granulomatosis associated with delayed hypersensitivity to cobalt.

Orofacial granulomatosis is a distinct clinical and pathological entity characterized by swelling of the lips and lower half of the face. Ulceration of the oral mucosa may also occur. Granulomas are seen histologically. Orofacial granulomatosis may occur in the Melkersson-Rosenthal syndrome, granulomatous cheilitis of Miescher, oral Crohn's disease, sarcoidosis and focal dental sepsis. The increased prevalence of atopy in patients with orofacial granulomatosis and the association with food intolerance suggests the possibility of a role for allergy in at least some cases.

Delayed hypersensitivity to 6-methyl-prednisolone in Henoch Schöenlein syndrome.

We report a case of allergic reaction to oral 6-methyl-prednisolone in a patient with Henoch Schöenlein syndrome. When this syndrome was first diagnosed the patient was started on 6-methyl-prednisolone orally and after 4 days he developed a pruriginous generalized maculo-papular eruption. The rash disappeared 1 week after withdrawal of 6-methyl-prednisolone. The skin tests performed 1 month after with main food allergens were negative. Patch test with 0.10 ml of solution containing 6-methyl-prednisolone 40 mg/ml was positive after 48 and 72 h. The cutaneous biopsy on the patch tested skin revealed a perivascular infiltrate of lymphocytes, histiocytes and eosinophils.

The diagnostic and prognostic significance of delayed hypersensitivity skin testing in patients with urological cancer.

The responses to several skin test antigens of patients with bladder or prostatic cancer has been compared with responses of normal controls. All of the controls and all of the patients with prostatic cancer (irrespective of the stage of the tumour or the method of treatment) showed responses to dinitrochlorbenzene. 80% of all patients with bladder cancer responded to DNCB, but a highly significant number of patients with advanced disease showed no response. This test appears especially useful in predicting the prognosis in patients with bladder tumours and its routine use is recommended. Response to candida extract, streptokinase/streptodornase (SKSD) and purified protein derivative (PPD) were also studied. No conclusion could be drawn as to their value as a prognostic index.
