[Surgical methods for the treatment of breast phyllodes tumors--a report of 319 cases].

UNLABELLED: Breast phyllodes tumors (FT) belong the fibroapitelial group of breast tumors arising in terminal ductulo-lobular unit (TDLU). Their incidence do not exceed 1% of all breast tumors. Biologicaly they can be divided into benign, borderline and malignant group. Incomplete tumor excision can be the reason for local reccurence. Malignant form of FT metastazise hematogenous most often in the lung. There is no uniform surgical opinion about the treatment FT. METHODS: We analyzed histopathology features of 319 FT of the breast surgicaly removed on Departement of surgery Institut of oncology and radiology of Serbia between 1.1.1985.-31.12.1994. Retrospective study of surgical treatment 84 patients with FT of the breast (69 benign, 4 borderline and 11 malignant) and 5 year follow up after surgery we analysed. RESULTS: local reccurence after surgery was found in 17 (20,2 %) patients(14 benign , 2 borderline and 1 malignant FT), pulmonary metastases in 6 (7,1%) patients with malignant FT. DFI was 21,3 months for local reccurences and 25,1 months for pulmonary metastases. DFS for al forms of FT was 71 % (p =0,7104) in 5-year follow up. CONCLUSION: According to biological behavior we propose wide excision for benign and borderline forms and simple mastectomy for malignant FT, and voluminous benign and borderline forms. Axillary disection is not necessary because lymphatic spread of malignant FT is unfrequent.

[Initial diagnosis of intra-abdominal hemorrhage caused by isolated splenic injury in blunt abdominal trauma].

Diagnosis of intraabdominal bleeding caused by spleen injury must be performed in the shortest possible period of time, with little risk for the patient, and with high preciseness. By its simple performance, high preciseness and little risk for the patient, DPL imposes as the predominant method in initial diagnostic of intraabdominal bleeding. Control and monitoring of lavage may duly signalize degree of bleeding. Preciseness of this diagnostic in our series ranges up to 93.3%. DPL method is especially important in a combined neurotrauma. Ultrasonography is a sovereign method in diagnostic of bleeding source as well as in monitoring of bleeding that from the very beginning does not require urgent surgical intervention. Its importance is in monitoring both intrasplenic and subcapsulary hematomas. It is not appliable in disturbed and haemodynamically unstable patients. It is in particular important in children where a maximum conservative attitude with respect to operative treatment has been assumed. CT takes the leading place with respect to preciseness of bleeding area, and the combined thoracoabdominal trauma. Preciseness of CT in our series comes up to 96.6%, but can be applied only in haemodynamically stable patients. Same as US of abdomen so the CT of abdomen represents a prominent method in monitoring of both intrasplenic and subcapsular hematomas, which do not require urgent surgical intervention.

The effect of guanidino substances from uremic plasma on insulin binding to erythrocyte receptors in uremia.

We have studied insulin binding to erythrocyte receptors in a group of 25 nonobese, nondiabetic uremic patients undergoing maintenance hemodialysis for 2-54 months and 14 healthy controls. Erythrocytes of predialyzed uremics bind significantly less insulin than control erythrocytes (p less than 0.01). Dialysis resulted in a rapid increase of insulin binding (p less than 0.001). The concentrations of plasma insulin and glucose remained essentially unchanged during 5-hour hemodialysis and did not significantly differ from the control values. The down regulation of insulin receptors in undialyzed patients in the presence of normal plasma insulin concentration indicates that factors other than insulin itself could be responsible for insulin receptor activity during uremia. The results demonstrated that creatinine, creatine and glycocyamine have a direct suppressive effect on insulin binding of postdialyzed plasma (p less than 0.05) in concentration of 1 mmol/l. This suggested that specific uremic toxins could play an important role in the mechanisms of altered insulin binding during hemodialysis. Despite the high concentration of these compounds in blood of uremics, the only common feature for these compounds is the presence of the guanidino group in the molecule.

Dental status in a group of adult diabetic patients.

The aim of this study was to determine the prevalence of dental caries, DMFT score and treatment needs in a group of diabetic patients (n = 222), mean age 46.9 yr, and to compare them to those recorded in a control group (n = 189), mean age 43.9 yr, using WHO criteria. Relations between the type and duration of diabetes mellitus, diabetic complications (retinopathy and neuropathy), diabetic control, and the subjects' DMFT status were separately studied. The results obtained revealed no difference in the prevalence of caries between the group of diabetics and the control group. Neither was any difference found in the mean numbers of teeth with fillings, but the number of extracted teeth per subject was significantly higher in the group of diabetics (12.3) than in the control group (9.7) (P less than 0.01). Type I diabetics were found to have a significantly higher number of teeth with fillings (4.05 vs. 2.22) than the non-insulin dependent diabetics (P less than 0.001). Type II diabetics, however, had a significantly higher number of extracted teeth (14.1 vs. 10.4) (P less than 0.001). There was no difference in the caries experience regarding duration of diabetes, diabetic control, or diabetic complications.

CPITN assessment of periodontal disease in diabetic patients.

The aim of this study was to investigate, using the CPITN system, the periodontal treatment needs in diabetic patients, and to shed additional light on the possible effects of the duration and control of diabetes on the periodontal status in these patients. A comparison was made between 222 diabetic patients (mean age, 46.9 years) and 189 control subjects (mean age, 43.9 years). Edentulous patients were not included in the study. The results indicated that diabetic patients demonstrated significantly more missing teeth (P less than 0.001). The mean number of missing sextants was also significantly higher in diabetics. Pathologic pockets of 6 mm or more were found in 1.3 and 0.3 sextants in the diabetic and control group subjects, respectively (P less than 0.001). Up to the age of 34, no differences were observed between the diabetic and control group subjects regarding pathologic pockets of 6 mm or more. Above this age, diabetics demonstrated significantly more sextants with deep pockets (P less than 0.001). Concerning the type of diabetes, no differences related to CPITN score were found between insulin dependent and non-insulin dependent diabetics. Neither were any differences found in the periodontal condition related to the duration and control of diabetes, whereas diabetics with advanced retinopathy demonstrated more sextants with deep pockets. Oral hygiene instructions and scaling were required in all patients from both study groups. On an average, 1.3 sextants in 50.9% of diabetics and 0.3 sextants in 17.9% of control subjects required complex treatment.

Blood glucose and free insulin levels after the administration of insulin by conventional syringe or jet injector in insulin treated type 2 diabetics.

UNLABELLED: The levels of blood glucose and free insulin were compared in 20 diabetic subjects (type 2) receiving one dose of a combination of fast-acting and intermediary-acting insulins in the morning by means of a needle syringe or a jet injector (SICIM, Italy), using minimum possible injecting power. A shift to the left in the free insulin profile, consequential to different pharmacokinetic characteristics of insulin when administered by means of a jet injector, was observed, although no significant differences were seen for free insulin levels. Statistically significantly higher blood glucose values (P less than 0.05) were recorded 6 and 9 h after insulin administration by means of a jet injector, as well as statistically significant higher MBG values (P less than 0.05), thus indicating a faster and shorter effect achieved in comparison to that produced by the syringe injected insulin. CONCLUSIONS: 1. When switching the method of insulin administration in patients from needle syringe to jet injections the power of the jet injector should be increased (it can be set in three different levels). If that is not possible, because of patient skin characteristics then the dose of intermediary acting insulin should be slightly increased. 2. No local or general side-effects were registered using minimum injecting power of jet injector. 3. The results of the controlled poll have shown that this method of insulin administration is less painful and simpler for patients. The great majority of the patients would like to possess a jet injector.

Filter paper blood sampling for glycated haemoglobin determination and its use in the control of diabetes mellitus.

Blood sampling on filter paper was tested for determination of glycated haemoglobin. The method showed coefficients of variation of 3.4% and 4.1%, and linearity coefficients of 0.978 and 0.91 for the microchromatographic and colorimetric methods respectively. A blood sample on filter paper impregnated with 5% ethylene glycol solution remains stable for 8 days at room temperature. In a group of 30 diabetics educated in the filter paper blood sampling technique, no statistically significant differences were registered among the mean values of their blood glucose profiles, glycated haemoglobin levels determined at the hospital and those obtained at home 14 days after discharge. In conclusion, the use of blood spotted on filter paper seems a cheap and convenient method for collecting, storing and transporting samples for analysis of glycated haemoglobins. It is also a useful alternative for home monitoring of diabetics. Moreover, it could also be useful in epidemiological studies of diabetes.
