OBJECTIVES: To describe the pattern and mutual relationships between basic biometric characteristics of the eye in a Central European Caucasian population. METHODS: A single-centre retrospective study of 2340 patients (965 males, 1375 females) scheduled for cataract surgery between 2014 and 2016. Measurements using laser interferometry included AL (axial length), K (average corneal curvature), ACD (anterior chamber depth), LT (lens thickness), CCT (central corneal thickness), AST (astigmatism) and WTW (white to white). Subjects were stratified by gender and controlled for age. Descriptive, correlation and regression analyses were performed on the data. RESULTS: The mean AL was 23.33 ± 1.01 mm - higher in males (23.59 ± 0.99 mm), in comparison to females (23.15 ± 0.99 mm). The elderly had lower ACD and higher LT, while males had higher AL independent of age. Furthermore, LT and K decreased with AL, while ACD decreased with LT and increased with AL independent of age and gender. CONCLUSIONS: The estimates of the biometrics are obtained on a large sample of subjects and can serve as normative values for Lenstar LS900 in the Central European Caucasian population.

Cíl studie: Srovnání fetálních ultrazvukových biometrických parametrů hlavičky (obvod – HC, biparietální průměr – BPD) a stehenní kosti (délka femuru – FL) s ohledem na délku těhotenství a pohlaví plodu. Typ studie: Prospektivní studie. Název a sídlo pracoviště: Gynekologicko-porodnická klinika, Ústav lékařské genetiky a fetální medicíny, Ústav preventivního lékařství LF Univerzity Palackého a FN, Olomouc. Metodika: Ultrazvuková biometrie byla prováděna v souladu s metodikou uvedenou v referenčních tabulkách. U všech plodů bylo změřeno HC, BPD a FL. Ze studie byla vyloučena riziková těhotenství, plody v poloze koncem pánevním a vícečetná těhotenství. Výsledky: Celkem bylo provedeno 427 ultrazvukových biometrií mezi 16.–38. týdnem těhotenství. Plody mužského pohlaví měly signifikantně větší obvod hlavičky (HC) i biparietální průměr (BPD) ve srovnání s plody ženského pohlaví a s délkou těhotenství rozdíl narůstal. V období do 20. týdne byl rozdíl (HC + 3,9 dne; 3,0 %, a BPD + 4,1; 3,2 %), mezi 20.–30. týdnem (HC + 6,8 dne; 4,3 %, a BPD + 6,9 ; 4,4 %) a po 30. týdnu (HC + 12,3 dne; 5,6 %, a BPD + 12,9; 5,9 %). V období do 20. týdne byl rozdíl mezi HC a FL u plodů mužského pohlaví + 2,1 dne (95%Cl 1,7–2,6; p <0,001), mezi 20.–30. týdnem + 3,4 dny (95%Cl 2,5–4,2; p <0,001) a po 30. týdnu + 9,7 dne (95%Cl 7,3–12,1; p <0,001). Závěr: Podle výsledků této studie mají plody mužského pohlaví signifikantně větší biparietální průměr i obvod hlavičky. Rozdíl je patrný již od 16. týdne těhotenství a narůstá s délkou gestace. Při nálezu diskrepance v ultrazvukové biometrii hlavičky plodu a délkou stehenní kosti by mělo být zohledněno i pohlaví plodu.
Objective: To compare female and male fetuses in terms of intrauterine ultrasound growth measurements (HC - head circumference, BPD - biparietal diameter, FL - femur lenght) depending on gestational age. Design: A prospective study. Setting: Department of Obstetrics and Gynecology, Department of Medical Genetics and Fetal Medicine, Department of Preventive Medicine, University Hospital, Olomouc. Methods: All ultrasound biometric measurements were performed according to the methodology published with the reference charts. Risk pregnancies, multiple pregnancies and breech presentations were excluded. Results: Fetal HC, BPD and FL were measured in 427 ultrasound examinations at 16 - 38 weeks. Male fetuses had significantly larger HC and BPD measurements compared to female fetuses and these differences increased with advancing gestation. In the 16 - 21 week scans estimated difference was (HC + 3.9 days, 3.0% and BPD + 4.1, 3.2%), during the 21 - 30 week scans (HC + 6.8 days, 4.3% and BPD + 6.9, 4.4%) and in the 31 - 38 week scans (HC + 12.3 days, 5.6% and BPD + 12.9, 5.9%) for males. Male fetuses had significantly larger HC compared to FL measurements. In the 16 - 21 week scans, estimated difference was + 2.1 days (95%Cl 1.7 - 2.6, P < 0.001), during the 21 - 30 week scans + 3.4 days (95%Cl 2.5 - 4.2, P < 0.001) and in the 31 - 38 week scans + 9.7 days (95%Cl 7.3 - 12.1, P < 0.001). Conclusion: This study suggests that male fetuses have significantly larger head circumference (HC) and biparietal diameter (BPD) measurements compared to female fetuses. These prenatal sex-related differences are established by as early as 16 weeks of gestation and tend to increase with advancing gestational age. In the case of discrepancy finding between head (HC, BPD) and femur lenght (FL) measurements the fetal gender should be taken into account.
BACKGROUND: A comparison of fetal ultrasonographic biometric parameters of the head (head circumference - HC, biparietal diameter - BPD) in breech presented fetuses. METHODS: Ultrasound biometry was performed in accordance with the method presented in the reference tables. In all breech presented fetuses, the HC, BPD and FL (femur length) were measured. High-risk and multiple pregnancies were excluded from the study. RESULTS: A total of 111 ultrasonographic biometries were performed between the 31(st) - 38(th) week of gestation. Fetuses in the breech position had a significantly lower BPD compared to HC and FL. The difference between BPD and HC was 16.2 days (95%Cl 14.3-18.1; p = 0.001). Maternal age at delivery was 20 - 36 years (average 28.1; median 28.0). CONCLUSIONS: According to our results, fetuses in the breech position have a significantly lower BPD compared to HC or FL. HC and FL parameters correlate with gestational age. In cases of ultrasonographic biometric discrepancy between BPD and FL, the fetal position should be taken into account. Breech-presented fetuses have an elongated head shape and ultrasound biometrics should evaluate its circumference (HC). It is important to responsibly interpret the results so as not to stress the expecting mother with suspicions of fetal pathology.

The paper presents the application of the human motion analysis systems in the criminology, in the fi eld of identifi cation of people according to the motion patterns, gait parameters. Human motion Analysis Laboratory at the Technical University of Košice has experience with video capturing system SMART with 6 cameras. It enables to evaluate human gait with relatively high precision. Th e main aim is to estimate and assess movement, abilities and changes in case of any pathology in clinical fi eld, e.g. rehabilitation, gait analysis utilisation, stability disorders and in sports medicine. One of new emerging application is motion analysis in criminology – especially in the fi eld of biometric identifi cation of people. Th is method seems to have lots of advantages as contact free design, unobtrusive and comfort, in comparison with the commonly used methods of identifi cation (e.g. fi ngerprints, hand geometry, palm prints, retina and iris scans).

OBJECTIVES: This study assessed the subchronic effects of a triazine compound, simazine, on common carp (Cyprinus carpio L.) though, via by means of biometric, biochemical, hematological, and histological examination. DESIGN: One-year-old fish were exposed to simazine at four concentrations, 0.06, (reported concentration in Czech rivers), 4, 20, and 50 microg L-1 for 28 days and compared to carp in a non-treated control group. RESULTS: Exposure of fish to simazine at 0.06 microg L-1 had no effect on measured parameters. However, exposure to simazine at the concentrations of 4, 20, 50 microg L-1 showed significant differences in biochemical, hematological, and histopathological profiles of fish compared to controls. CONCLUSION: Our data suggest that simazine in the recorded environmental concentration 0.06 microg L-1 had no effect on common carp. Subchronic exposure to 4, 20, and 50 microg L-1 of simazine was associated with alterations in biochemical and hematological indices and in fish organ tissues.
