Human papillomavirus (HPV) cervical lesions: results from 300 Italian women studied with DNA hybridization techniques and morphology.

Human papillomavirus cervical infection was investigated in a series of 300 unselected women by comparing morphological diagnoses (cytology and histology) with results of DNA hybridization techniques (filter in situ hybridization of DNA from exfoliated cervical cells and Southern blot analysis of HPV-DNA in cervical biopsy specimens). The prevalence of HPV cervical infection diagnosed by PAP smears was 11.6%. Despite disadvantages, filter in situ hybridization was confirmed to be particularly useful for screening purposes to detect HPV in cervical scrapings. In 3 cases it was the only applicable method for diagnosing "high-risk" HPV infection. Southern blot hybridization of tissue DNA with HPV 16-DNA revealed the presence of this virus in 8 cases, and HPV 31-DNA and HPV 42-DNA in 1 case each.

[Health status of journalists and organization of work in a national daily newspaper].

A multidisciplinary investigation was performed on 173 reporters (53 men and 20 women) of a newspaper. The microclimate and illumination conditions of the main seat, in which the use of VDT was beginning, were satisfactory, although not all the instruments were correctly adjusted. A very low percentage of reporters working in the main center was suffering from arterial hypertension indicating the presence of the "healthy worker effect". The values of plasma cortisol and arterial blood pressure of 10 reporters of the main seat, except two cases, changed normally during the evening hours. It is to point out that among the reporters there was significant correlation between spondylosis and astigmatism. The psychological investigation evidenced that the reporters were aggressive, eager of success and with constant attention. The EMG biofeedback demonstrated in the reporters with a more prolonged period of employment nervous tension and difficulty in relaxing. Particularly, in the reporters of the main center, the Stait-Trait Anxiety Inventory was more altered than in those of the peripheral seats.

Usefulness of the TRH test in the management of patients with differentiated thyroid cancer.

Thirty patients thyroidectomized for differentiated thyroid cancer were studied. Serum TSH was assayed in basal conditions and after TRH stimulation, while patients were in suppressive therapy with thyroid hormones. The basal TSH was normal in all the patients and less than 2 microU/ml in 20 patients. The TRH test was negative (no TSH response) in 27 patients and in all the cases with the basal TSH lower than 2 microU/ml.

Papillary carcinoma of the thyroid. A clinicopathologic study of 241 cases treated at the University of Florence, Italy.

A clinicopathologic study of 241 cases of papillary thyroid carcinoma treated at the University of Florence Medical School, Florence, Italy is presented. The features of greatest prognostic value were patient's age at presentation, small tumor size, total encapsulation, extrathyroid extension, multicentricity, and presence of distant metastases. The prognosis of the disease was not influenced by the pattern of tumor growth, presence of solid areas, initial presence or subsequent development of cervical lymph node metastases, type of initial thyroid operation, performance of neck dissection, or prophylactic administration of radioactive iodine. It is concluded that conservative thyroid surgery in the form of lobectomy, without neck dissection or prophylactic administration of iodine 131 (131I), constitutes adequate therapy for most cases of papillary thyroid carcinoma. More extensive therapy should be considered for older patients and for those in whom the tumor exhibits extrathyroid extension or easily detectable multicentricity.

Prognostic value of the 131I whole-body scan in postsurgical therapy for differentiated thyroid cancer.

Seventy-two patients affected by differentiated thyroid cancer underwent whole-body scan seven days after the postsurgical thyroablative treatment with 131I. In 40 patients this scanning did not reveal any area of 131I uptake outside the residual thyroid parenchyma. During the follow-up period, no signs of functioning tumors were detected in these patients and therefore, there was no need for further therapeutic treatment with radioiodine. From this results it is legitimate to conclude that whole-body scan control can be significantly postponed without diagnostic inaccuracy for those patients whose postthyroablative scans do not reveal diffuse tumor localizations.

Correlation of isotopic cisternographic patterns in multiple sclerosis with CSF IgG values.

Thirty-eight patients with multiple sclerosis (MS) were examined with isotopic cisternography (IC) in order to study cerebrospinal fluid (CSF) dynamics. Cisternography was also performed in 15 patients with amyotrophic lateral sclerosis and in 14 with senile dementia of the Alzheimer type as controls. IC pattern of "mixed" type was found in 18 MS patients and all those with Alzheimer senile dementia examined, while the IC examination did not show abnormality in any of 15 patients with amyotrophic lateral sclerosis. In MS patients, the abnormal IC picture proved to be significantly correlated with the CSF IgG values as calculated by Link's and Tourtelotte's formulas. The abnormal IC in MS may be due to altered CSF reabsorption or increased transependymal flow, or it may be related to the abnormal concentration of IgG.
