[Hypocomplementemic urticarial vasculitis syndrome].

HISTORY AND ADMISSION FINDINGS: A 40-year-old woman was admitted with recurrent membranoproliferative glomerulonephritis. For many years she had been suffering from joint pains and attacks of angio-oedema of the upper and lower lip. Physical examination was unremarkable except for marked oedema and urticaria of the trunk and limbs. INVESTIGATIONS: Skin biopsy revealed urticaria with vasculitis. Complement fractions C3, C4 and C1q were reduced, and C1q antibodies were demonstrated. DIAGNOSIS, TREATMENT AND COURSE: The findings of urticaria with vasculitis and reduced complement levels as cardinal symptoms together with joint pains, glomerulonephritis and C1q antibodies as minor symptoms were diagnostic of hypocomplementaemic vasculitic urticaria syndrome. The urticaria disappeared immediately when immunosuppressive treatment with prednisolone and cyclophosphamide was started, and the nephritic signs regressed. CONCLUSION: Differentiation of a vasculitic and a non-vasculitic form of chronic urticaria provides an initial step in delineating the underlying disease. Severe systemic disease such as collagen disease or vasculitis is not rare in vasculitic urticaria and requires long-term immunosuppression.

Color-coded Doppler sonography in the diagnosis of abdominal masses.

A man in his forties was operated on for testicular cancer on the right-side with subsequent radiotherapy. Two years later, another tumor was found on the opposite side and surgically removed, followed by polychemotherapy. In the follow-up period, CT scanning and ultrasound showed large abdominal masses which were suspected to be metastases. Before initiating four cycles of chemotherapy, we checked their nature by Doppler sonography and found them to be recently developed abdominal varices due to an alcoholic liver cirrhosis. We were able to demonstrate that Doppler sonography can provide further information and is easy to use.

Role of human chorionic gonadotropin in patients with pure seminoma.

Human chorionic gonadotropin (beta-hCG) and alpha-fetoprotein (AFP) are widely established specific and sensitive tumor markers for nonseminomatous testicular cancer. In 106 patients with pure seminoma, a highly sensitive method detected beta-hCG both before and repeatedly during therapy. The low detection limit of the test (0.3 IU/l) coincided with the 95 percentile of a group of 60 healthy blood donors. Its 100 percentile of < 1.0 IU/l was applied as the upper limit of the normal range. In 30.2% of our patients with pure seminoma, elevated beta-hCG levels were noted prior to orchiectomy. The levels returned to normal in 76% of these patients thereafter, and in 34% after additional irradiation or chemotherapy. During an observation period of 2-84 months, all beta-hCG-positive patients were in complete remission. Prior to semicastration, 1 patient showed extremely high beta-hCG levels, while in another patient, beta-hCG and AFP were elevated simultaneously. In both cases, tumor marker levels did not seem to agree with the histology of 'pure seminoma' and rather suggested the presence of nonseminomatous tumor cells. Increased AFP levels contradict the presence of a pure seminoma and indicate a nonseminomatous testicular tumor. The same holds true for strongly elevated beta-hCG levels, whereas levels of up to 200 IU/l correlate with the diagnosis of pure seminoma.
