Transferrin gene expression in the mammary gland of the rat. The enhancing effect of 17 beta-oestradiol on the level of RNA is tissue-specific.
1993
We have investigated the physiological factors which regulate transferrin gene expression in the mammary gland of the rat. Our studies by dot blot analysis have demonstrated that multiple doses of 17β-oestradiol (OE2; 0·5 mg/kg per day for 3 days) elicit a specific 3·5-fold increase in the transferrin mRNA levels in the mammary glands of virgin rats. The hormonal action of OE2 in mammary tissue was specific for the transferrin gene, as judged by hybridization with β-actin cDNA. The accmulation of transferrin mRNA induced by OE2 treatment was similar to the developmentally regulated expression of the gene observed during the reproductive cycle. The steady-state level of mammary transferrin m…
Involvement of Different networks in mammary gland involution after the pregnancy/lactation cycle: Implications in breast cancer
2015
Early pregnancy is associated with a reduction in a woman's lifetime risk for breast cancer. However, different studies have demonstrated an increase in breast cancer risk in the years immediately following pregnancy. Early and long-term risk is even higher if the mother age is above 35 years at the time of first parity. The proinflammatory microenvironment within the mammary gland after pregnancy renders an "ideal niche" for oncogenic events. Signaling pathways involved in programmed cell death and tissue remodeling during involution are also activated in breast cancer. Herein, the major signaling pathways involved in mammary gland involution, signal transducer and activator of transcripti…
Drainage großer Brustdrüsenabszesse unter ästhetischen und funktionellen Aspekten
1991
In 11 puerperal women, a breast abscess was treated by drainage from the inframammary fold. Eight patients wished to continue breast feeding. During the healing period, the babies were not breast fed on the operated side. In 3 patients, the skin over the abscess necrotised, resulting in a defect of 1 to 2 cm. In 2 patients, a small seroma had to be punctured after removing the drainage tube. Aesthetic results were judged by the patients as good. Resumation of suckling on the operated side revealed only 15 to 20% milk yield compared to that of the other breast. This treatment meets aesthetic and function-preserving criteria.
Inwazyjny rak piersi w ektopowej tkance gruczołowej zlokalizowanej w dole pachowym. Opis przypadku
2021
Breast cancer is the most commonly diagnosed malignancy in women in Poland. Rare, unusual forms of breast cancer remain a diagnostic problem. The incidence of ectopic breast glandular tissue in the general population varies between 0.4 and 6%. The same abnormalities and diseases as in the anatomical mammary gland may develop in this tissue. Breast cancer may develop as well. We present the case of a 36-year-old woman, who went to the doctor because of a nodule in the right armpit presented for 2 years. The patient was referred to a surgeon with suspicion of an epidermal cyst. The lesion was surgically removed and in the histopathological examination, the diagnose was: invasive breast cancer…

Cardiovascular Implantable Electronic Device Infection and New Insights About Correlation Between Pro-inflammatory Markers and Heart Failure: A Syste…
2021
Introduction: Surgical approaches to treat patients with abnormal pro-inflammatory parameters remain controversial, and the debate on the correlation between hematological parameter alteration in cardiac implantable electronic device (CIED) infection and the increase in mortality continues.Methods: We performed a systematic review using the PubMed, Scopus, and Cochrane Library databases. Twenty-two articles from May 2007 to April 2020 were selected and divided according to the following topics: prevalence of microbes in patients with CIED infection; characteristics of patients with CIED infection; comparison between patients who underwent and did not undergo replantation after device extrac…
The Morphology of Hormone Induced Structural Changes in the Female Breast
1970
Many morphological, physiological, and biochemical investigations have contributed to the classification of the endocrine regulatory mechanisms responsible for development and function of the mammary gland. These studies received their crucial impetus when the synthesis of the sex hormones had been achieved and from their experimental use. The history of the use of these drugs is thus also the history of the concept of control of the mammary gland by hormones. The individual factors and combinations of factors responsible for the normal growth of the glandular structure of the mammary gland, for its secretory function, and for its pathomorphology have been elucidated by systematic studies. …
Spiral-Computertomographie der Mamma
1994
Aim To evaluate the use of spiral CT in the diagnosis of breast lesions. Material and methods 93 female patients with suspicious or uncertain mammographic findings were examined by CT before and after contrast enhancement according to the following practical method: table movement, 6 mm/s, slice thickness 6 mm, increment 4 mm, contrast 200 ml, injection rate 3 ml/s, scan start 50 s after the beginning of the injection. Histological confirmation was present in 85 patients. Results All 44 invasive carcinomas were recognised. They were characterised by intensive focal contrast uptake. Only 2 out of 7 intraductal carcinomas were not shown by CT. 36 out of 38 benign lesions were correctly diagno…
Nachsorge des Mammakarzinoms
1994
7865 follow-up examinations were performed on 420 patients who had had surgery for carcinoma of the breast; there were 2755 radiographs of the chest, 2660 sonographic examinations of the upper abdomen and 2450 contralateral mammograms. The most common findings were metastases seen on the chest radiographs during the 13-24 and 25-60 months intervals in 4.7% of cases. The incidence increased with initially higher tumour stages and in ductal carcinomas. Sonography of the upper abdomen showed 4.3% of liver involvement, mostly between the second and fifth year; this was independent of tumour stage or the histology of the primary tumour. Positive mammography of the contralateral breast was found …
Evaluation of routine follow-up after surgery for breast carcinoma.
1986
Close postoperative follow-up of patients with breast cancer permits the early detection of possible recurrence of disease. Such follow-up allows for the detection of a tumor mass, that is small enough to permit adequate treatment leading to an increased survival time and better quality of life. Thus we studied 85 patients treated by radical mastectomy in stages I, II, and III during the period from December 1977 to June 1982. Among 82 patients, 41 had axillary node involvement and received adjuvant chemotherapy with C.M.F. All patients received a strict follow-up. Thirty-two patients showed recurrence of the disease, with 28. 1% being discovered while still asymptomatic. Seventy-five perce…
