[Retrospective studies on the relation between fibrocystic disease and cancer of the breast with therapeutic conclusions].

On the basis of 597 cases of benign and malignant tumoral, respectively dysplastic diseases of the breast, operated at the IInd Surgical Clinic of Tirgu-Mureş during the period 1977-1983, the authors consider the fibrocystic disease (FCD) of the II and III degree as a facultative precancerous lesion. The extremely high frequency of FCD associated to the mammary cancer in young women, as well as of intense epithelial proliferations and intermediate forms, of transition from typical epithelial hyperplasias to the atypical forms observed in some of these cases, is pointed out. The 4 cases (1.94%) of mammary neoplasms which occurred late after a mammary sectorectomy performed for FCD illustrate that the risk of mammary neoplasm in FCD is 7.4 times higher than the mammary cancer rate in women without FCD. In the extensive forms of FCD with marked epithelial proliferations, especially if additional risk factors are also present, the authors recommend a uni- or bilateral subcutaneous mastectomy, a uni- or bilateral simple mastectomy respectively. They deem necessary the setting up, in all departments of general surgery, of an adequate organizational framework for the dispensary care, the hormonal therapy and the control of women with FCD.

[The beneficial effect of physical training in hypertension].

Hypertension is present in epidemic proportion and is associated with a markedly increased risk of developing numerous cardiovascular disorders. All current treatment guidelines emphasise the role of nonpharmacological interventions, physical activity included, in the treatment of mild to moderate hypertension. A large number of studies have demonstrated that regular exercise reduces the incidence of hypertension. In addition to preventing hypertension, regular exercise has been found to lower blood pressure (10 mmHg average reduction in both systolic and diastolic pressure), improve lipoprotein-lipid profiles and insulin sensitivity. As part of the initial treatment, exercise is recommended for 12 months in patients with stage 1 hypertension, with no other coronary risk factors and no evidence of cardiovascular disease, and for as long as 6 months in those with other risk factor, but not diabetes. In patients with diabetes, cardiovascular disease or with stage 2 or 3 hypertension, drug therapy should be initiated first. Dynamic exercise of moderate intensity, 50-75% VO2max, (e.g. brisk walking, cycling) for 50-60 minutes, 3-5 times per week, is preferable to vigorous exercise because it appears to be more effective in lowering blood pressure. In addition to reducing hypertension, physical activity improves other cardiovascular risk factors.

[Difficulties in diagnosis and surgical treatment of subacute and chronic thyroiditis].

Out of a total number of 875 cases of thyroid affections of various origins, hospitalized in the two surgical clinics of Tîrgu-Mureş, the authors selected 16 cases of subacute and chronic thyroiditis. They indicate the difficulties encountered in establishing the diagnosis before surgery, a fact that determined wide excisions in extremely difficult local conditions. They suggest, as a first therapeutic attitude, a conservative treatment with steroid drugs, antibiotics and roentgentherapy (when necessary), and, if such treatments fail, or when malignancies are suspected, as well as compression phenomena have developed, surgical treatment preceded by an extemporaneous anatomo-pathological examination. When thyroiditis is diagnosed surgery should be limited to decompressing incisions.

[Hepatic suppurations requiring segmented or atypical hepatectomies].

Following studies of cases with hepatic suppurations the authors indicate the necessity for regular or atypic hepatectomies. The extension of the suppurative process in the liver made necessary the ligature of the great sagital vein and the authors show, on the basis of anatomic and topographical data (hepatic segmentation), that it is necessary to extend the hepatectomy to the IV-th para-median segment. The authors also present the indications for bi-segmental right hepatectomy in segments VII-VI as well as of the total left regulated hepatectomy.

[Osler--Rendu Disease: an example of a family clustering in a genetic disorder].

The case of a 75 years old woman with hereditary hemorrhagic telangiectasia (HHT) is presented. This condition is an autosomal dominant mucocutaneous and visceral fibrovascular dysplasia in which telangiectasia, arteriovenous malformations and aneurysms may be widely distributed throughout the cardiovascular system. It is usually recognized as a "triad" of telangiectasia, recurrent epistaxis and a family history of the disorder.

[5-fluorouracil treatment of acute pancreatitis and of pancreatic and duodenal fistulae].

In acute pancreatitis the mechanism involved in the auto-amplification of morbid phenomena can be suppressed in most of the cases by inhibiting the pancreatic secretion. This can also enhance the repair of pancreatic, duodenal and jejunal fistulae. On the basis of experimental studies carried out by Johnson, and on the clinical studies of Guttmann, as well as on original studies done by the authors, Ftorafur was included in the complex therapy of acute pancreatitis, and of pancreatic and duodenal fistulae. A group of 14 cases of acute pancreatitis, were treated. These included 5 necrotic-haemorrhagic pancreatitis, and 9 oedematous pancreatitis. The drug was given by continuous intravenous perfusion in doses of 1,200-1,600 mg per day, for a period of 6-12 days. In all the cases the clinical improvement of the patients as well as recovery of normal values of blood amylase were spectacular, and full recovery was achieved in all the cases. Ftorafur was also used in 3 cases of pancreatic fistulae, and in 2 cases of duodenal fistulae, and recovery was also achieved in a very short time. On the basis of this experience, although small, the authors recommend the introduction of Ftorafur in the complex therapy of acute pancreatitis, as well as in that of pancreatic and duodenal fistulae. Following administration of Ftorafur no adverse effects were noted, and in the doses mentioned above this drug did not delay the repair of surgical wounds.

[An experimental study of the action of 5-fluorouracil on the function and cytomorphology of the exocrine pancreas].

The authors have taken up previous studies by Martin (1969), and by Johnson (1973), and carried out an experimental study on white rats aimed at evaluating the morpho-functional changes of cells from the exocrine pancreas under the influence of 5-fluorouracil (Ftorafur), a cytostatic drug which is a general inhibitor of protein synthesis by cells. Ftorafur was injected in amounts of 2.3 mg/100 g of body weight, and a significant reduction was noted in the secretion of bicarbonates, amylase and lipase by the pancreas of the animals. Cytologic changes were also noted in the pancreatic tissue of these animals, indicating, on the one hand, a deficient protein and enzyme synthesis by the pancreatic cells, and a blocking of the mechanism of discharge of zymogen granules, on the other hand. The most intensive morpho-functional changes were noted following repeated administration of Ftorafur, probably due to the cumulative effects of this substance at the level of secretory pancreatic cells. The authors consider that 5-fluorouracil inhibits to a considerable degree the synthesis of pancreatic enzymes, and as such it can be used as a therapeutic means for the reduction of the external secretion of the pancreas.

[Gamma interferon induced in human leukocytes by phytohemagglutinin: its production and biological characteristics].

Human gamma type interferon (IFN) preparations were obtained through phytohemagglutinin stimulation of leukocytes from the peripheral blood. Biological value of these preparations varied between 160 u and 800 u/ml, depending on leukocyte incubation medium, culture system and inductor conservation. The rising of the antiviral activity through association between gamma (3 u) and alpha (27 u) interferons was revealed by the virus quantity reduction (in this case the vesicular stomatitis virus was used) during a 24-hour multiplication cycle. The protection ensured by the mixture of the two types of interferon was about ten times higher than the additive effect of the two preparations. Study of the antiproliferative activity of a gamma interferon preparation was conducted on two human cell lines of tumoral origin (T-10 from a glioblastoma, and HEp-2) and revealed the difficulties to quantify precisely this property of the crude gamma interferon preparations.
