[Cytological diagnosis of the breast. Aspiration technics].
Over the past twenty years the use of fine needle aspiration techniques in breast cancer has spread worldwide, becoming a routine examination in the early phase of the study of palpable breast nodules. In this paper, the Authors review the state-of-the-art of fine needle aspiration, illustrating the most common methods and the various modifications made by operators. A new type of metal handle is also described which facilitates the collection of cells for cytological tests. Previously reported studies show that operators must be trained and supplied with suitable instruments in order to obtain valid results and to minimise the number of false positives and false negatives. There are very few complications to fine needle aspiration and none are severe, with the exception of pneumothorax which however has a frequency of under 3%. The majority of Authors agree that there should be more collaboration between the clinician and the anatomopathologist in order to increase the reliability of the technique. Fears of spreading cancer along the path of the needle have been dispelled following clinical experience over time. The survival of patients with breast cancer undergoing fine needle aspiration in the diagnostic phase does not differ from that in other patients.
Osteosynthesis in fractures of the femoral neck in the young adult.
The authors report 21 cases of fracture of the femoral neck in the young adult followed-up after a minimum of 2 years, which is a sufficient amount of time to be able to evaluate cephalic necrosis. The results obtained with the various methods of osteosynthesis were: excellent: 38%; good: 33.5%; fair: 9.5%; poor: 19%. Emphasis is made on the effectiveness of the Garden classification system for prognosis and treatment, and several aspects of the method used are discussed.
The Ilizarov method for the treatment of non-union in the humerus.
The authors report 7 cases of septic and aseptic pseudoarthrosis in the humerus, with or without tissue loss, treated with the Ilizarov apparatus. The method proved to be therapeutically effective, guaranteeing a short amount of time required for consolidation, with bone callus of the periosteal type which was abundant and mechanically effective, immediate functional recovery, and no important complications.
Two-level fractures of the tibia: indications for surgery.
The authors report 35 cases of two-level fracture of the tibia emphasizing the problems related to surgical treatment and local complications. Based on the results obtained, they propose several different methods according to precise indications: 1) for closed fractures or those with grade I exposure: internal fixation; 2) for grade II and III open fractures: external fixation and any necessary complementary surgical procedures.
[Knowledge and attitudes regarding family clinics on the part of women who use or do not use them].
Thanks to large civil participation and to the women's movement in 1975 a law has been approved that institutes family health clinics. This law is dedicated in particular to health and general services for women and to family planning. The Hygiene Department of University of Perugia has studied during this time: the family health clinics (FHC) activity in order to determine how well it is meeting the institutional aims. The knowledge and the attitudes of women with respect their use of FHC which have been projected onto the community. Health Education has a very important role because it is quite often basis for acceptance of FHC by women. The identification of all aspects of cultural resistance is very important. To this point a research project has been completed. The focal point of this research concerns women and their ability to profit from available information, as well as their attitudes and evaluation of the FCH. This study has been using a representative sample of Umbrian women, aged 16-50 ys old, at March 1987; the sampling method was of two stage. On the whole 1647 observations have been made by means of a mail questionnaire. The responders were very low (about 25%), so the results obtained must be considered with extreme caution. Generally there is a positive opinion on family health clinic: women are linked to a service of the community. They express satisfaction with the service. They express opinions on both positive and negative aspects. Even if the first approach is generally determined by a gynecological visit, the users redefine the service in a less ambulatory manner and into a more consultative one. In fact, users consider the FHC as a reference for women's problems. They underline the lack of sexual and health consulting service. There is demand for counseling for infancy problems, sterility, health education and sexual education. Even the non-users have a sufficiently clear idea of the family health clinics. Non-users view the FHC as a service for women's problems as well as relationship problems.
[Correlation between indicators of the fertile period of the menstrual cycle and ultrasonically-determined ovulation].
The authors intend to verify the reliability of some indices set up for the assessment of the fertile period of the menstrual cycle in women. The patterns of the following indices were studied and related to the day of ovulation, as detected by pelvic ultrasonography, in 42 cycles in healty women: the urinary surge of luteinising hormone tested by radioimmunoassay (R.I.A.), urinary surges of estrone-3-glucuronide (E1-3-G) and pregnanediol-3 alpha-glucuronide (Pd-3-alpha-G) tested by chemiluminescence immunoassay, cervical mucus at the vulva and basal body temperature (B.B.T.) recorded by self-observation. The patterns of these parameters have shown a various temporal relationship and reliability for detection of the fertile days of the menstrual cycle.

Metabolic approach to the diagnosis and treatment of atherosclerotic peripheral vascular disease.
Metabolic and clinical peculiarities of patients with peripheral vascular disease (PVD) were evaluated in two studies. In the first study lipid and lipoprotein composition of 20 patients with PVD were examined. Twelve of these patients were normolipidemic, the other 8 hypertriglyceridemic. Ten normolipidemic and ten hyperlipidemic age-matched subjects served as controls. High density lipoprotein cholesterol (HDL-C) levels were markedly reduced in the hypertriglyceridemic, both with (35.1 +/- 5.0 mg/dl) and without (36.2 +/- 11.7 mg/dl) PVD as compared to the normolipidemic patients (47.0 +/- 6.3 mg/dl) and controls (48.1 +/- 10 mg/dl). All the PVD patients showed an increased apolipoprotein B content in the very low density lipoproteins (VLDL) as compared to controls (p less than 0.001). A significant correlation between VLDL-cholesterol and apo B levels was detected in both groups; however, two distinct populations could be clearly separated (slopes of the regression lines: PVD patients = 0.350; controls = 0.215, p less than 0.0001). These data suggest a possible discriminatory power of VLDL-apo B levels in PVD patients independent of other metabolic parameters. In the second study, the clinical activity of metformin (N, N-dimethylbiguanide) a widely used antidiabetic agent, on arterial blood flow was evaluated in 15 patients with PVD. Flow was determined by quantitative strain-gauge plethysmography during a cross-over trial, comparing 6 months of drug and placebo administration. Metformin (850 mg tid) significantly increased arterial flow after a standardized ischemia in both sequences. In spite of the minimal changes of plasma lipid levels during metformin, a highly significant increase of HDL-C levels (+8.3% during the whole treatment) was demonstrated. Plasma levels of isoprotein AI-1 were also raised during the metformin period. Although the mechanism/s of the beneficial effects of metformin on flow cannot, at present be defined, the reported results underline the significant therapeutic potential of this metabolic drug treatment in PVD.
