[New perspectives in color ultrasound in breast diagnosis].

In recent years, ultrasound has become established as part of the diagnostic evaluation of breast tumours. Not replacing, but complementing mammography, ultrasonic investigations increasingly represent a sensitive means of early diagnosis. Thermography, on the other hand, has proved of relatively little value and doesn't play a significant role today. Lately, Colour Doppler sonography has been used for differentiating tumour-associated blood supply patterns--however, sensitivity and specificity were not as high as initially expected. Colour spectrum analysis of local findings in comparison to the remaining glandular tissue, however, seems to be a promising method in the differentiation of ultrasound findings of uncertain tumour status. A fibroadenoma shows no significantly different colour density as compared to surrounding tissue. In carcinoma, on the other hand, one regularly finds a hyperintensive zone with sharp margins. In 70 patients, who had breast tumours, we attempted the differentiation of benign and malignant findings with the help of colour spectrum analysis. Postoperatively, these results were validated by histology. With the exception of one mesenchymal tumour, the Doppler diagnosis was identical to the histopathological findings.

[Laparoscopic treatment of ovarian tumors in menopausal women].

OBJECTIVE: The authors report their experiences in the laparoscopical therapy of ovarian tumours with 94 postmenopausal women. STUDY DESIGN: The patients were treated in the Department of Gynecology at Göppingen Medical Center from March 1, 1992 until December 31, 1993. Tumour marker CA 125 was not within normal limits (< 35 U/ml) in all patients. Preoperatively all findings were verified by ultrasound examination. In some cases, cysts were single-chambered, smooth-bounded or without endovegetations. Choice therapy has been bilateral adnectomy without opening the ovarian cyst and without trauma to the ovary capsula. Adnectomy was performed by bipolar coagulation and sharp preparation. In every case the specimen was positioned intact in a "Lap-Sac" and then removed via second puncture. In case of ultrasonographic or laparoscopic-macroscopic conspicuous findings an obligatory fast microscopic random sample was performed. RESULTS: In one case the microscopic test sample revealed carcinoma of the ovary--the operation was terminated by standard laparotomy. No other cases showed signs of malignancy. There were no peri- or postoperative complications. The average operation lasted 35 min (20-80 min), all operations were performed without significant blood-loss. Usually the patients were discharged at the 4th to 6th postoperative day. CONCLUSION: This operation-technique guaranteed "oncological aseptic" results at any time of operation. Therefore you can waive the standard laparotomy for the benefit of laparoscopy in many elderly patients even with suspicious findings.

Endodermal sinus tumor of the ovary. Clinicopathologic study of 6 cases.

6 cases of endodermal sinus tumor of the ovary are presented. In 4 patients pure endodermal sinus tumor was found microscopically. 1 patient had endodermal sinus tumor in one ovary and gonadoblastoma in the contralateral one. In another case endodermal sinus tumor was accompanied by an embryonal teratoma. Histologically, the tumor had characteristic features with meshwork of spaces and channels lined by embryonal cells, glomerulus-like structures known as Schiller-Duval bodies, solid aggregates of epithelial cells, hyaline basement membranes and round, PAS-positive small globules found both intra- and extracellulary. In 1 patient the elevated serum alpha-fetoprotein was stated. All patients were treated surgically with adjunctive radiation and/or with chemical agents. None of them were cured. The median duration of survival amounted to 8.5 months. Discussing the value of the more recent approach to diagnostic and therapeutic methods found in the literature, it must be emphasized that the demonstration of elevated serum alpha-fetoprotein in patient with that tumor lend not only further support to its yolk sac origin but also might be useful to monitor response to the therapy applied. It is also of prognostic significance by indicating the presence of residual or recurrent disease, even in its subclinical stage. Combined postoperative irradiation and triple chemotherapy according to the VAC regimen of patients can prevent recurrence and in some cases even may cause permanent remission of the neoplasm.

[Histocompatibility antigens (HLA) in children with lipoid nephrosis].

Actual knowledge on the HLA relationship with the primary glomerulopathies, with particular reference to steroid - sensitive nephrosis of childhood, is surveyed. Occurrence of HLA B-8 and B-35 in this nephropathy has been investigated. The studies involved 47 patients aged between 3 and 15 years and 117 healthy children from Lower Silesian region. It has been showed, that HLA B-8 is present more frequently in sick children, than in healthy controls. The situation is reverse in case of HLA B-35 antigen. However, the difference is statistically insignificant. A probability of the lipid nephrosis sensitivity to corticosteroids can not be predicted on the base of the presence of these HLA antigens.
