Our experience regarding precautional chemotherapy in breast cancer.
14 patient with breast cancer of loco regional diffusion (M0), 4 of whom had negative axillary lymph nodes, were administered precautional chemotherapy with CMF, on the basis of anatomo-clinical prognostic elements (size of the neoplasia, grading (tumoral limits, neoplastic embolisation etc.). Such elements with data on hormonal receptors allowed us to select the patients with high relapse risk, to undergo medical treatment.
Diabetes in pregnancy. An epidemiologic study by Department of Obstetrics and Gynaecology of Sassari University from 1974 to 1983.
We examined 102 pregnancies in 59 diabetic women by Department of Gynaecology and Obstetrics of Sassari University from 1974 to 1983, we evaluated pregnancy and labor proceeding, perinative morbidity and mortality. Our issues show a perinative mortality high yet (14.8%), not always comparable to severity of maternal diabetes, that's mainly due to insufficient number of controls undertaken from patients for their por medical education. Recently diabetic pregnant women have getting used to routine controls of metabolic balance, pregnancy evolution and fetal well-being through biochemical and biophysic monitoring; that allows to obtain an improvement of perinative mortality.
Alpha-fetoprotein assay in patients treated with low-dose oral contraceptives.
AFP has proven to be a useful marker for liver neoplasms. The authors assayed AFP plasma levels in patients taking low-dose estro- progestinics . Patients were divided into three groups on the basis of their living habits. No difference was found in any group between AFP levels before and after treatment. However, in the group of smokers using oral contraceptives AFP levels were significantly higher.
Incidence and duration of breast-feeding in a group of primiparae after physiological delivery.
A study has been performed on the incidence and duration of breast feeding in a group of 103 primiparous women who delivered in the Obstetrics Department of Sassari in 1980. The most important maternal variables that could be related with breast feeding were maternal age, level of school education, maternal feelings concerning the present pregnancy and maternal information concerning the advantages of breast feeding.

Prolactin plasma levels and oral contraceptives at low dosage.
In the present study the Authors consider whether estroprogestins at low dosage may influence the basal levels of plasma Prolactin in a group of patients subdivided on the basis of their different ways of life. The results show that oral contraceptives containing 30 microgrammes of EE do not induce modifications on PRL levels; however these are significantly (p less than or equal to 0.01) lower in the smoker group. It has therefore been hypothesised that smoke may interfere with the regulatory mechanisms of PRL, even if the practical effects of such action in the ambit of the physiopathology of reproduction is not yet clear.

Determination of adhesive rate constant in normal and neoplastic homogeneic cells.
The adhesive rate constant (ARC) of neoplastic SGS-2 cells which have a low contact inhibition, is remarkably higher than that of normal homogeneic fibroblasts. This is in contrast with the mutual adhesion theory which states that the loss of contact inhibition is strictly related to the loss of cell recognition and consequently to the loss of cell adhesion capacity.
[The psychodynamic nursing theory by Hildegard E. Peplau].
Peplau's theory is one of the early Nursing theories, published in 1952. The nurse-patient relationship consists of four steps (orientation, identification, development and conclusion). In these steps nurse could have the role of foreign, reliable person, teacher, guide in nursing care, substitute and consultant. Nurse-patient relationship is influenced by psychobiological experiences (needs, frustrations, conflicts and anxiety) which need dynamism. Peplau thinks that Nursing care is an important opportunity for nurse because she can help patient to complete the infancy psychological tasks (learning to rely on other people, learning to show satisfaction, self-identifying, and developing ability in sharing) if these are not completed. For these reasons Nursing, by Peplau, is a maturation strength of civilization.
[Family dynamics: sleep quality of women caregivers of family members with Alzheimer disease].
This replication study/Riccio 1996) sets out to explore the Quality of sleep of 34 women primary caregivers of Alzheimer's Disease patients at home. A descriptive, correlational and longitudinal design has been used. Key aspects considered were the quality of nocturnal sleep, the daytime sleepiness, the hours of caring, the educational level, the employment, the time for personal needs and the levels of depression and anxiety. After an initial interview, the caregivers were asked to fill in several instruments to measure the variables taken into consideration. The caregivers presented poor quality in their sleep. Quality of nocturnal sleep was negatively affected by more hours of caring (p < 0.02), high depression and anxiety levels (p < 0.05 and 0.007 respectively). The education level, the employment outside home and the amount of time spent for themselves, positively affected the quality of sleep (p < 0.01, 0.04, 0.05 respectively). This research pointed out that hours of caring, directly and indirectly, cause sleep problem to Alzheimer's Disease caregivers enhancing nursing care implications.
[Stress, anxiety, and depression among caregivers of patients with Alzheimer's disease].
The aim of this study was to evaluate the levels of stress, anxiety and depression in women caregivers of Alzheimer's disease patients. A convenience sample of 37 women caregivers living with the patients was studied using a descriptive-correlational design. A sociodemographic questionnaire with scales measuring the variables taken into consideration were utilized. Caregivers were 60 years old, devoted to the patients 17 hours of caring per day and had only 1 hour for their personal needs. The 54, 21 and 29% of the sample had high levels respectively at the stress, anxiety and depression scale. Stress, anxiety and depression were positively correlated with caring hours, sleep problems in caregivers and behavioural disturbances of the patients; and were negatively correlated with free time and time spent out of the home. Implications for nursing care resulting from this study consists in giving more support to caregivers in order to avoid their excessive involvement in caring and in guaranteeing educational interventions to help caregivers to manage the behavioural disturbances of the patients.
