Simultaneous involvement of the jejunum and the colon by type-1 neurofibromatosis.

Type-1 neurofibromatosis (NF-1) or Von Recklinghausen disease is an autosomal dominant hereditary condition that may affect the gastrointestinal tract in 25% of cases and which takes three main forms: ganglioneuromatosis, stromal tumors, and tumors in the duodenum and periampullar region. Not infrequently, these patients present with gastrointestinal bleeding. We present the case of a 48-year-old patient diagnosed as having NF-1, with relapsing episodes of gastrointestinal hemorrhage, in which we discovered the simultaneous presence of a stromal tumor in the jejunum together with polypoid and diffuse ganglioneuromatosis in the colon.

Drug use and its relationship to other behavior disorders and maladjustment signs among adolescents.

Based on a representative sample of 1,312 students 13 to 19 years of age from Mallorca, Spain, we used 19 variables from an anonymous questionnaire to define three groups of problems frequently found in adolescents: depression, deviant behaviors, and the use of alcohol, tobacco, and illicit drugs. We have found a close relationship between drug use and deviant behaviors which shows no relationship with depressive symptoms. There is a small group which uses drugs with no relationship to deviant behaviors. There are also relationships between these problem behaviors and sleeping difficulties, enuresis, weight problems, family difficulties, etc., which leads us to think of a network of connections with other problems of the adolescent and his family.

[Lymphography for the prognosis of carcinoma of the cervix (author's transl)].

Ninety-two patients with carcinoma of the cervix, who had lymphograms before treatment, were observed for a period of three to five years. In patients with lymph node metastases 57.1% were found to have recurrences or metastases, or died during that period. Amongst patients with normal lymphograms the corresponding figure was 11.3%. These findings were true for each stage of the disease. Follow-up studies with histological examination of the lymph nodes have shown that the prognosis of carcinoma of the cervix is totally different if lymph node metastases are present. Separation into cases with good and bad prognosis can be achieved by pre-treatment lymphography. The radiological findings concerning lymph nodes should therefore be included in the classification of carcinoma of the cervix; the T.N.M. calssification of U.I.C.C. makes this possible.
