Deidentification of facial photographs: a survey of editorial policies and practices.

We analysed all journals from two Journal Citation Reports (JCR) categories: 'Dentistry, Oral Surgery and Medicine' and 'Otorhinolaryngology' published in 2018 for their policies on publishing facial photographs and actual practices of publishing these photographs in articles. We extracted the following data for each journal: JCR category, impact factor, volume, issue, instructions for authors regarding ethical issues, instructions for photograph deidentification, journals' references to standard research and publishing policies, presence and type of published clinical images, separate informed consent for the publication of patient photograph and methods of deidentification. The sample included 103 journals, which published 568 articles with 1404 clinical images.

Syndecans and Enzymes for Heparan Sulfate Biosynthesis and Modification Differentially Correlate With Presence of Inflammatory Infiltrate in Periodontitis.

Periodontitis is a common degenerative disease initiated by the bacteria in subgingival biofilm. The exposure to bacterial biofilm triggers host inflammatory response whose dysregulation is ultimately responsible for the destruction of hard and soft periodontal tissues resulting in tooth loss. To date, significant effort has been invested in the research of the involvement of host cells and inflammatory mediators in regulation of inflammatory response in periodontitis.

Secular trend of menarche in Zagreb (Croatia) adolescents.

Objective: To study the secular trend of menarche in high-school urban adolescent girls (Zagreb, Croatia) over the last two decades, and to evaluate the possible impact of worsening of socio-economic conditions on age at menarche during the Croatian War of Independence (1991-1995).

Study Design: Three surveys of female adolescents aged 15-19 years: (a) 523 girls interviewed in 1990, (b) 888 girls interviewed in 1997, and (c) 399 girls interviewed in 2010. Self-reported age at menarche (in decimal years) was presented by age groups and year of interview.

Biological aspects of the development and self-concept in adolescents living in single-parent families.

In this study we investigate whether there are differences between adolescents who grow up in single-parent families and those who grow up in nucleus families. We have decided that there are no differences in the physical development between the adolescents who are growing up in single parent families and those growing up in nucleus families. There is no difference in the self-concept between these two groups, except in the ethical and moral self-image of adolescents living with one parent.

Fetal hand movements and facial expression in normal pregnancy studied by four-dimensional sonography.

Aim: To evaluate the developmental pattern of fetal hand movements and facial activity and expression during the second and third trimester of pregnancy by four-dimensional ultrasound (4D-US).

Subjects And Methods: A total of 25 fetuses in uncomplicated pregnancies were analyzed; 15 fetuses at 13 to 16 weeks and 10 fetuses at 30 to 33 weeks of gestation were studied with abdominal 4D-US. After standard assessment in two dimensional (2D) real-time B mode, a 4D mode was switched on.

Prenatal diagnosis: what does four-dimensional ultrasound add?

Introduction: The key benefit of 4D ultrasound lies in providing real-time 3D images of embryonic or fetal movements, previously limited by technological advancement.

Aim: To classify types of first trimester embryonic and fetal movements in normal pregnancies as seen by 4D sonography.

Results: Three types of movements can be visualized in the first trimester: gross body between seven and eight weeks, limb movements after ten weeks and complex limb movements after 11 weeks of gestation.

Prognostic value of steroid hormone receptors concentration in patients with endometrial carcinoma.

The concentrations of progesterone receptors in endometrial tumors of 160 patients were analyzed with respect to survival and presence of clinicopathologic prognostic factors. The concentration of 25 fmol/mg of proteins for progesterone receptors appeared to be most powerful for prediction of survival. The survival was also significantly correlated to age, depth of myometrial invasion and clinical stage of the tumor.

Tumor cell cycle in patients with stage I endometrial carcinoma.

Flow cytometric cell cycle analysis was performed on paraffin-embedded blocks from 49 patients with stage I endometrial carcinoma. Care was taken to separate tumor tissue from normal tissue in each specimen; normal tissue was used as a control for each individual specimen. DNA index, proliferative activity, and cell DNA aneuploidy were correlated with known parameters of tumor malignancy.

Prognostic impact of peritoneal cytology in patients with endometrial carcinoma.

In 169 patients with all stages of endometrial cancer peritoneal cytology was performed and the finding correlated to the stage of disease, histologic grade, depth of myometrial invasion, tumor site in the uterine cavity, menstrual status, frequency of recurrence and 5-year survival. In 23 (11.6%) patients malignant cells were found in the peritoneal washing.

[Clear cell carcinoma of the female genital tract].

From 1980 to 1989 clear-cell carcinoma was diagnosed in 66(4.2%) out of 1562 adenocarcinomas of the female genital tract: in the ovary, 2.9% in the endometrium, 9.

[Immunoglobulins in women with cancer of the uterine body (before treatment)].

Thirty-five women aged 40 to 79 years with the carcinoma of the body of the uterus were before treatment examined for humoral immunity to find out if the diminished function of the immunological system and immunodeficiency lead to an increased proneness to malignant diseases. Concentrations of total serum proteins, electrophoresis of proteins, and the quantitative determination of G-, A-, and M- immunoglobulins were performed. Lower mean values of IgG (11.

Carcinomas of the cervix and corpus uteri in humans: stage-dependent blood levels of substance(s) immunologically cross-reactive with insulin.

Inasmuch as the elevated levels of substance(s) immunologically cross-reactive with insulin (SICRI) in a diabetic woman with carcinoma of the corpus uteri decreased following the surgical removal of the uterus and ovaries, 80 women with cervical carcinomas of various stages and 70 women with carcinomas of the corpus uteri of various stages were screened for the levels of SICRI and C-peptide. The levels of SICRI in the second, third, and fourth stages of the cancers were elevated (up to six times above the normal levels of immunoreactive insulin) and stage-dependent. The levels of C-peptide, which are related to the insulin-secreting activity of pancreatic beta-cells, were normal and independent of the stage of cancer.

[The value of the lymphocyte transformation index induced by mitogens in cervical carcinoma].

Dynamics of immune reactivity in patients with the carcinoma of the cervix was determined. The transformation of their lymphocytes was induced in vitro by phytohemagglutinin (PHA), and the transformation index--a correlate of immunological reactivity--was determined at the following intervals: just before the start of the therapeutic procedure, at the end of the procedure, and every three months afterwards. Very low values of the transformation index, i.
