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.

Predictive factors of malignancy in patients with adnexal masses.

INTRODUCTION: Good preoperative tumor triage is essential for choosing the appropriate approach. OBJECTIVE: The study aim was to identify factors from standard preoperatively collected data, which could predict the nature of adnexal masses prior surgery. MATERIAL AND METHODS: The study involved all women treated in the Clinic for Gynecology and Obstetrics Clinical Center of Serbia for adnexal tumors throughout a period of 18 months. On admission, detailed anamnestical and laboratory data were obtained and ultrasound scans were performed. Obtained data were compared with hystopathological findings of tumors. Methods of correlation and logistic regression were applied to create association models. RESULTS: Three new models for predicting tumor nature were achieved from anamnestical data, characteristics of women and tumors, and laboratory analyses. Two statistically significant (p = 0.000) equations were obtained for anamnestical data and characteristics of women and tumors, while three were made for laboratory analyses. Sensitivity of anamnestical malignancy index (AMI) was 73.33%, specificity 72.87%, positive predictive value (PPV) 39.49% and negative predictive value (NPV) 91.88%. Sensitivity of characteristic malignancy index (CMI) was 92.38%, specificity 67.36%, PPV 40.59% and NPV 97.34%. Sensitivity of laboratory malignancy index (LMI) was 56.45%, specificity 90.24%, PPV 68.63%, and NPV 84.57%. CONCLUSIONS: The best predictors of malignancy are menopausal status, body mass index (BMI), age, metastases, ascites, tumor marker CEA level, and erythrocyte sedimentation rate (ESR). Along with the risk of malignancy index (RMI), for more reliable triage and preoperative tumor evaluation the authors propose introduction of another three indexes (AMI, CMI, LMI) in clinical practice.

The absence of the vomer in the first and early second trimester of pregnancy - a new marker of trisomy 21 and trisomy 13.

PURPOSE: The aim of this study was to measure the two frontomaxillo-facial (FMF) angles: the FMF-vomer (FMF-v) and the FMF-palate (FMF-p), and to visualize the vomer in the 1(st) and early 2(nd) trimester, in order to ascertain whether they can be used as markers for trisomy 21 and trisomy 13. MATERIALS AND METHODS: A 2D ultrasound scan was performed in the 340 normal and 12 abnormal pregnancies, using the linear, convex and endovaginal probes. RESULTS: We visualized the FMF angles within 1 to 5 minutes in 253 (72 %) of cases by using the linear probe. FMF-v angle was significantly smaller that the FMF-p angle (79.8° vs. 89.7°, 71.5° vs. 84.5° for the two trimesters, respectively), and that the value of both angles decreased in the second trimester. There was not one single case of trisomy in which vomer could be identified in the 1 (st) and early 2 (nd) trimester. The FMF-p angle failed to present difference between normal cases and the ones with trisomy (89.5°). There was not one single case of trisomy (21 or 13) in which vomer or FMF-v could be identified in the first or early second trimester. The diagnostic accuracy of vomer as a marker for trisomy was 0.985. CONCLUSION: If the vomer cannot be visualized in the 1 (st) and early 2 (nd) trimester, it is important to check the karyotype, and it is not necessary to measure the FMF-p angle. The high resolution probe (L 12 - 5 Mhz) enables easier assessment of the vomer.

Impact of Phytoestrogens on Serum Lipids in Postmenopausal Women.

Objectives: The aim of the study was to assess the impact of soy- and red clover-derived isoflavones on serum lipid levels in postmenopausal women and to compare the effects to the lipid levels of healthy postmenopausal women without phytoestrogen supplementation. Materials and Methods: Blood levels of triglycerides, total cholesterol and cholesterol fractions were assessed. Measurements were performed before treatment and at 6-month intervals over a period of 18 months. The investigation included 74 healthy postmenopausal women randomized into three groups according to treatment. The first group of 23 patients received soy-derived isoflavones, the second group (26 patients) was given red clover-derived phytoestrogens, while the third control group (25 patients) received no supplements. Results: Mean triglyceride, cholesterol and LDL levels of patients in the control group were significantly higher than in both the soy and the red clover groups (p < 0.001) at all three time points, while mean values did not differ significantly between the soy and the red clover groups. The mean HDL levels of patients in the control group was significantly lower than in both the soy and the red clover groups (p < 0.001). Conclusions: Phytoestrogen supplementation had a positive metabolic effect on serum lipid levels in postmenopausal women. The impact on serum lipids levels was similar for soy and red clover.

Balloon dilatation of cricopharyngeal achalasia.

A 6-month-old male infant with difficulty swallowing, recurrent aspiration pneumonia and failure to thrive was diagnosed with cricopharyngeal achalasia. Normal oral feeding and no further aspirations followed a single catheter balloon dilatation.

Cholestasis caused by biliary botryoid sarcoma.

A 4-year-old boy with a short history of jaundice and hepatomegaly was studied by endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC). A large obstructing choledochal tumour was found at the level of cystic duct insertion and at surgery, a botryoid sarcoma was removed. Subsequent cytotoxic therapy was complicated by persistent dilatation of the extrahepatic bile ducts which necessitated eventual excision. There was no evidence of persistent tumour.

The role of the accessory pancreatic duct of Santorini in pancreatic drainage in children (with emphasis on choledochal cyst patients).

Pancreatic drainage patterns have been studied by endoscopic retrograde cholangiopancreatography (ERCP) in four children with choledochal cyst (CC). The first two had mild or chemical pancreatitis; the third had a history of recurrent cholangitis and was diagnosed as chronic pancreatitis. The fourth manifested with severe, acute pancreatitis. All children were found to have an impaired flow through the papilla of Vater. In the first three cases, the duct of Santorini (DS) seemed to play an important role in the pancreatic drainage. In the fourth case, however, the duct was found to be absent. ERCP findings in additional eleven children without CC also were reviewed, and in this group the DS did not seem to play any significant role in pancreatic drainage. These results indicate that in children with common bile duct (CBD) anomalies, the DS may relieve the obstruction and ameliorate the pancreatitis.

Recurrent pneumonia caused by diffuse oesophageal spasm.

A 14-month-old severely retarded girl with a history of regurgitation, aspiration, and recurrent pneumonia was found to suffer from diffuse oesophageal spasm. This diagnosis was made by oesophageal cineradiography. This case suggests that diffuse oesophageal spasm is an oesophageal motility disorder that causes respiratory disease in the retarded child.

Infantile achalasia treated by pneumatic dilatation.

A 4 month old girl with oesophageal achalasia was successfully treated with a single pneumatic dilatation. A subsequent barium swallow showed almost normal oesophageal caliber. During the following eighteen months, vomiting and feeding problems did not recur.

[Obstructive bronchitis caused by an unrecognized foreign body in the esophagus]. / Obstruktivni bronhitis uzrokovan neprepoznatim stranim telom jednjaka.

A 9-month-old girl with 4 months history of recurrent wheezy bronchitis, dysphagia and pneumonia, had impacted, radiolucent oesophageal foreign body (nipple). Its extraction was followed by complete amelioration of the respiratory symptoms. In children with unexplained respiratory symptoms and dysphagia oesophagoscopy may be of high diagnostic and therapeutic value.
