[Refusal of catamnestic testing].

From a study of catamnesis involving 866 persons admitted to hospital for psychiatric care (Enquête de Lausanne, Ciompi--Müller), the authors have examined the patients who refused this test, that is to say 10%, trying to determine the characteristics. In comparing the two groups they came to the conclusion that there were no significant differences between them, and that the overall results of the statistic research would not have been modified had the above mentioned persons been included. They therefore recommend discretion, as well as the respect of the individual by not forcing the person to look backwards.

[Inflammatory pseudotumor of the lung. Apropos of a case].

A case of inflammatory pseudotumor of the lung is reported and the essential features are recalled. Depending on morphology or pathogenesis this disease has received various designations, e.g.

[A case of pseudo-tumoral lymphoid hyperplasia or Castleman's disease].

The relatively rare pseudotumoral lymphoid hyperplasia (benigh lymphoid or reactive lymphoreticular hyperplasia; pseudolymphoma; Castleman's disease) arises from the lymph nodes, usually in the mediastinum. The disease assumes tow histologically and clinically different forms: the first, angiofollicular, is often symptomless, while the second, lymphoplasmocytic, is sometimes associated with a marked chronic inflammatory syndrome. The etiology is unknown, but is probably a reaction of the lymphoplasmocytic system to an antigen, possibly of viral origin.

[Paralysis after tetanus prevention].

A rare case is presented of isolated paralysis of the left dentatus muscle in a 29-year-old woman following antitetanus vaccination by adsorbed toxoid injection in the left shoulder. In the light of a literature review the peculiarities of this case are pointed out and the risk factors which emerge from the patient's history are stressed. The discussion centres on the most favorable site for injection of toxoid, the controverted etiology of the affection and the desirability of some form of treatment.

[Localized malignant mesethelioma of the peritoneum revealed by a parietal mass].

A report is presented on a rapidly evolving, fatal case of localized malignant mesothelioma of the peritoneum revealed by an abdominal wall mass. Although the tumor was at an advanced stage, a large excision of the primary mass and its metastases was attempted. On the basis of this observation the authors point out the main features of these rare tumors, the diagnostic difficulties they involve, and their possible relationship to asbestos dust exposure.
