Early fetal heart ultrasonography as additional indicator for chromosomopathies.

OBJECTIVE: First trial of estimating values of scans of fetal heart structures (FHS) in first trimester of pregnancy, as more primary facts of possible chromosomopathies. MATERIALS AND METHODS: The study included 2,643 fetuses that were examined in first trimester of pregnancy on Sono CT convex (C5-2MHz), endovaginal (ev 8-4MHz), and linear transducers (L12-5MHz) during a period of eight years. Fetal heart was evaluated using appropriate software with broad-band transducers and color Doppler, Sono CT, and HD ZOOM technologies. The scan was performed by three experienced physicians. FHS were based on: left and right ventricle morphology; AV valves (atrioventricular) position and existence of primal ostium; relationship of left ventricle outflow tract (LVOT) and right ventricle outflow tract (RVOT) and great vessels on three vessel view (3VV) and estimation of ductal and aortic arch. RESULTS: Several developments, one being the ability to identify fetuses at risk for cardiac defects combining nuchal translucency (NT), ductus venosus (DV) Doppler, and evaluation of tricuspid regurgitation, have prompted reconsideration of the role of the first trimester prognostic factor of fetal evaluation. In low-risk pregnancies group, 36 (1.8%) fetuses were found to have congenital heart disease (CHD), and in high-risk pregnancies the number of fetuses with CHD was 75 (12%). Genetic amniocentesis or chorionic villus sampling (CVS) was performed in all fetuses with CHD. Forty-two (37.8%) fetuses with CHD were found to have chromosomal anomalies. Out of 111 fetuses with CHD 39 (35.1%) had an nuchal translucency (NT) above three mm. Out of 42 fetuses with chromosomal anomalies and CHD, 29 (69%) had an increased NT. CONCLUSION: Using first trimester fetal echosonography constitutes a further step in the earlier recognition of chromosomopathies, even in low risk groups. Still further steps are necessary as all facts of good clinical practice. In order to offer further benefits during pregnancies, improvements in diagnostics are still required.

Influence of regularity of checkups during pregnancy on prevalence of asymptomatic bacteriuria and maternal behaviors regarding urinary infection prevention.

PURPOSE OF INVESTIGATION: T0 investigate how the regularity of checkups in pregnancy influences maternal behavior regarding habits in prevention of urinary tract infection (UTI), the level of information, and finally the prevalence of asymptomatic bacteriuria (AB). MATERIALS AND METHODS: This study included 223 women with regular and 220 women with irregular checkups in pregnancy were given the questionnaire on the following issues: frequency of sexual intercourses during pregnancy, the regularity of bathing and changing of underwear, the direction of washing the genital region after urinating, the regularity of antenatal visits to gynecologist, and the subjective experience concerning the quality of the information received by the healthcare provider. RESULTS: AB was present significantly more frequent in group of participants with irregular controls during pregnancy compared to group with regular checkups in pregnancy. The prevalence of AB was higher in those women who had irregular prenatal checkups. Maternal behaviors related with the risk of urinary infections are more frequent among women with irregular prenatal care. CONCLUSION: Results of the present study emphasize the importance of regular prenatal care in AB prevention.

Prognostic value of survivin expression in Wilms tumor.

PURPOSE: To determine survivin expression patterns in Wilms tumor (WT) and compare it with the expression in normal renal tissue. Also, to analyse cytoplasmic and nuclear survivin expression in relation to histological type, prognostic group and tumor stage. METHODS: Immunohistochemical expression of survivin was analysed in 59 cases of primary WT and in 10 normal kidney specimens, taken from the same patients, but distant from the tumor. RESULTS: 51 out of 59 cases of WT (86.44%) showed decreased cytoplasmic survivin expression and 4 out of 59 cases of WT (6.78%) showed nuclear overexpression of survivin. There was statistically significant difference in the frequency of decreased cytoplasmic expression of survivin in individual components of WT (p=0.005). Decreased cytoplasmic expression of survivin in epithelial, blastemal and stromal component was found significantly more often in low stage WT compared to high stage WT (Fisher exact test, p=0.0002, p=0.002, p=0.002, respectively). There was no statistically significant difference in the frequency of survivin nuclear overexpression between different stages of WT (Fisher exact test, p=0.564), histological types (Fisher exact test, p=0.915), or between different prognostic groups (Fisher exact test, p=1). CONCLUSION: Decreased survivin cytoplasmic expression or nuclear overexpression may be related to favorable prognosis of WT.

Is lymphocytic thyroiditis a unique type or merely a type of Hashimoto's thyroiditis?

AIM: Objective of the study was to clarify the role of apoptosis in the pathogenesis of lymphocytic thyroiditis (LT) and the existence of difference between Hashimoto's thyroiditis (HT) and LT. METHODS: We evaluated levels of antithyroglobulin and antithyroperoxidase antibodies, the apoptosis by in situ Cell Death Detection-TUNEL and the expression of Bcl2 and Bax by immunohistochemistry in thyroid tissues from 16 patient with HT, 10 with LT and 10 with euthyroid goiter-EG (control group). RESULTS: It was found that apoptosis of thyrocytes in HT (mean 3.05%, SD 1.29%) and LT (mean 2.70%, SD 1.17%) was statistically significantly higher than EG (mean 0.56%, SD 0.23%), but the difference in the percentage of thyrocytes between HT and LT was not statistically significant. In HT the percentage of apoptotic infiltrating lymphocytes (mean 0.59%, SD 0.23%) was smaller than in EG (mean 2.26%, SD 1.42%), but it showed no significant difference in comparison to LT. The expression of Bax in infiltrating lymphocytes in HT (mean 0.72%, SD 0.34%) was statistically significantly higher than LT (mean 0.11%, SD 0.06%). The level of thyroglobulin was lower in HT compared to LT (P<0.01) and compared to EG (P<0.01). The level of antithyroglobulin/antithyroperoxidase antibodies was higher in HT compared to LT (P<0.01) and compared to EG (P<0.01). There was no statistically significant difference in the level of thyroglobulin and level of antibodies between LT and EG. CONCLUSION: These results suppose that apoptosis represents one of significant mechanisms in the pathogenesis of both HT and LT and that LT probably differs from HT.

Multiple cutaneous metastases of advanced prostate cancer: case report and a review of the literature.

Between 2% and 9% of malignant tumours are metastasizing to the skin. Cutaneous metastases from carcinoma of the prostate occur infrequently. Their presence is associated with poor prognosis. We report the case of a 65-year-old man with carcinoma of the prostate, presenting multiple metastases in the scrotal skin region.

Radial scar of the breast--a confusing lesion.

Radial scar is a confusing lesion of the breast which represent a premalignant lesion. It looks like a tubular carcinoma but histologically we can see two rows of cells in tubules. Mammographically there are some typical but not specific signs: (1) the presence of the central radiolucency, (2) the presence of radial long thin spicules, (3) varying appearance in different projection, (4) radiolucent linear structures parallel to spicules, and (5) abscence of palpable lesion or skin changes. All these signs make the "black star" appearance. Authors reanalyzed 21 from 26 woman with the radial scar diagnosis. Aim of our study was to investigate the different morphologic changes in view of differential diagnosis, frequency and potential prognostic importance of the different lesions. According to our findings we can conclude that the radial scar is unpalpable, subclinical lesion which can be seen on mammography but the final diagnosis is histological.

[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.
