Plurihormonal Cosecretion by a Case of Adrenocortical Oncocytic Neoplasm.

Adrenocortical oncocytic neoplasms (oncocytomas) are extremely rare; only approximately 159 cases have been described so far. The majority are nonfunctional and benign. We describe an unusual case of a functional oncocytoma secreting an excess of glucocorticoids (cortisol) and androgens (androstenedione and DHEAS), a pattern of plurihormonal cosecretion previously not reported in men, presenting with endocrine manifestations of Cushing's syndrome. The neoplasm was considered to be of uncertain malignant potential (borderline) according to the Lin-Weiss-Bisceglia criteria.

[Surgery of lung metastasis in childhood]. / Cirugía de las metástasis pulmonares en la infancia.

From 1975 to 1987, we have operated 20 cases with lung metastases. They were 12 females and 8 males with ages between 1,6 and 12 years old (average of 5 years). The histology of the primary neoplasia was: 13 cases with Wilms' Tumors, 3 cases with Ewing's Sarcoma and 1 case with Neuroblastoma, Rhabdomiosarcoma, Hepatoblastoma and Neuroectodermic Tumor of Askin. We found 38 metastases and there were performed through a Thoracotomy 28 wedge resection, 7 pulmonary lobectomies and 3 biopsies. The operative mortality was 0%. The most frequent location of the lesion were on medium and lower lobule of the right lung. The survival was 70% (14 cases) after 4 years of average of the follow up. The survival for Wilms Tumors was 61% (8 cases) and all patients with Ewing's Sarcoma, Rhabdomiosarcoma, Neuroblastoma and Neuroectodermic Tumor of Askin were alive. The Thoracotomy is a useful method for therapy of tumors in children with lung metastases associated to chemotherapy and radiotherapy.

[Addicted patients. Attitude of nursing personnel]. / Pacientes toxicómanos. Actitud de enfermería.

Inside the realm of therapeutic relationships, one recognizes the importance of the nurse's attitude towards patients as one of those elements bearing influence on the objectives desired by the nursing profession. This study compares the attitudes towards via parenteral drug addicts held by nursing students and non specialized nurses. By means of a pilot study which used a selfadministered Litcker scale questionnaire developed by the study authors, two samples were selected: a student sample (n = 40) and a non specialized nurse sample (n = 40). These variables were evaluated in the two samples: age, professional experience, and the frequency in sporadic care for via parenteral drug addicts. The conclusion drawn from this study is that the attitude of nursing students is significantly more positive towards via parenteral drug addicts than the attitude held by non specialized nurses. The adoption of a more negative attitude towards these patients occurs at the start of a nurse's professional career.

[Schizophrenia. Nursing approach. Current perspectives]. / Esquizofrenia. Abordaje de enfermería. Perspectivas actuales.

OBJECTIVES: To review recent publications which deal with the role nurses have regarding schizophrenia. Besides strict pharmacological treatment, the authors place value on the need to get involved with the deficit provoked by this disease and the usefulness of providing aid and support to patients' families, due to a belief that nurses can play a more decisive, innovating role in these areas. SOURCES: Publications about nurses' roles with patients diagnosed as schizophrenics published from 1995 to 2000 and listed in the Medline data base.
