[Use of microcomputers in biomedical research. Project and implementation of an analysis of variance program. Computer notes].

Clinical and experimental numerical data evaluation requires microcomputer programs which greatly facilitate both the ease and speed of handling statistical data processing tasks. In present study designing and construction of variance analysis program is approached for application of computers to surgery. It is an approach which allows a physician who has some familiarity with programming techniques to rapidly construct and use a family of programs for statistical manipulation of numeric information.

[Benign-thyroid nodule: what's therapy? Personal experience].

INTRODUCTION: Solitary thyroid nodule is an important pathology with an incidence of 2-5% in Italian population. The diagnosis was based on clinical exam, laboratory tests and ultrasonographic evaluation. MATERIALS AND METHODS: The study undertook has the purpose to assess the usefulness between lobe-isthmusectomy (with corresponding risk of possible relapse and complications for reintervention) and total thyroidectomy, (with corresponding post-surgical treatment complications), for benign thyroid disease with solitary nodule, on selected cases for disease and corresponding risk factors, in the retrospective clinical study, using laboratory tests and ultrasonographic evaluation. The study was conducted on 80 patients admitted from 1994 to 2000 with diagnosis of benign thyroid nodule and operated with lobeisthmusectomy. In seven patients the operation had to be converted in total thyroidectomy. RESULTS: Operative mortality was nil and long-term results at a mean follow-up of three years are encouraging. DISCUSSION: The main advantages of lobe-isthmusectomy for benign solitary thyroid nodule consist in less postoperative complications and less hospital stay. CONCLUSION: Therefore our experience has carried us to consider the lobectomy which treatment choice for all those benign thyroid diseases, with, solitary nodule.

[Post-thyroidectomy hypocalcemia].

INTRODUCTION: The correlation between hypocalcemia and total thyroidectomy could be correlated to the influence practice from the TSH hormone on the thyroid C cells, in fact in conditions of hyperthyroidism the low values of the thyrotropin is correlated to a reduction of the plasmatic concentration of calcitonin and consequently of calcemia. of our study is verify the incidence of the hypocalcemia post-tyroidectomy and appraise the effectiveness of the pharmacological treatment with calcium salts and possibly D vitamin. MATERIALS AND METHODS: Of the 432 operated patients, 348 has stayed subjected to total thyroidectomy and 84 to loboistmusectomy. In none case subjected to emityroidectomy has been verified a hypocalcemia in the post-operative and in 67 cases in which we have administered pre-operative calcium salts orally, calcemia has sustained within acceptable values. RESULTS: Our experience only 1'11.2% of the patients subjected to total thyroidectomy they have presented a reduction of the calcemia to the of under of the 7.10 mg/dl and they have stayed subjected medical therapy with calcium salts in ev in the symptomatic forms, and to oral therapy in patients absent symptoms, while in two cases is not been practiced any therapy because the symptomatology has disappeared spontaneously DISCUSSION: Syndrome hypocalcemica has determined from the deficit-also transitory-parathyroid glands, from the action of the calcitonin (it favors the amassing of the calcium in to bon), and from a reduced bony reserve of calcium. In fact in those patients operated for a euthyroid goitre or for thyroid tumor the saving of the parathyroid glands avoids the outbreak of hypocalcemia (7, 8). Therefore the physio-pathological mechanism responsible of symptoms (excluded the medical causes: pharmacological treatments with steroid, oral conraceptives, diuretics, salts of lithium, oral antacid and diazepam) (9) also not being still of the all known, it would have his primum movens in the parathyroid glands ischemia. CONCLUSIONS: The precocious evaluation of the calcemia in the period post-operative is useful to discern the patients that will require of a pharmacological treatment of support, so that avoid of the serious and permanent damages to the varied organs.

[Neuroendocrine surgery in Parkinson's disease: comparative analytical evaluation of approaches to microsurgical adrenalectomy. Experimental studies].

In this experimental contribution to the study of neurobiological interactions between adrenal medullary graft and CNS, is presented a model to estimate the approaches to rat adrenalectomy using statistical inference techniques. Eighteen rats were divided into three samples. The members of every sample were left adrenalectomized using lombotomic, anterior transperitoneal and posterior approaches respectively. A score was attributed to every experimentally meaningful parameter, according a previously well established plan. Scores were tested by analysis of variance and by previously planned orthogonal comparisons. Mean, standard deviation of every sample score and confidence interval for mean difference were computed. Statistical analysis results show that, objectively, there is a meaningful difference between anterior approach and posterior or lateral approach, anterior approach being more difficult then posterior or lateral approach, while there is not meaningful difference between posterior and lateral approach. Subjectively, on the contrary, there are not meaningful differences between three approaches to left adrenalectomy statistically.

[A case of breast metastasis in bladder urothelioma].

A case of isolated mammary metastasis from surgically untreated urothelial vesical carcinoma is discussed. An integrated chemo-radiotherapeutical treatment had been planned, due to bad general condition; after this, an optimal subjective benefit and good objective response (reduction in lesion diameter < 50%, MR) were obtained. An isolated breast lesion appeared ten months after; its metastatic nature was only indirectly suspected by mammographic and echographic features. Only immunohistochemical study, realized on percutaneous needle biopsy specimen, definitively confirmed the urothelial metastatic origin. In present work, biological and prognostic significance of mammary metastases and the needing of distinguishing them from primary breast neoplasm are analysed, basing on the literature review.
