Dystrophic epidermolysis bullosa: oral findings and problems.
2006
Dystrophic epidermolysis bullosa (DEB) is one of the three major types of epidermolysis bullosa (EB), an inherited cutaneous disease with blister formation following minor trauma. A subtype of DEB is recessive dystrophic epidermolysis bullosa, Hallopeau-Siemens type (RDEB-HS), where marked scarring leads to deformities of extremities. In RDEB-HS the mucous membranes may also be involved and form adhesions with ankyloglossia and microstomia. Oral hygiene is difficult. A 7-year-old boy with RDEB-HS was brought to the Johannes Gutenberg University dental clinic with dental pain. He had multiple carious lesions, poor oral hygiene and gingivitis. Because he was noncompliant and had microstomia, …
Longitudinal associations between poor reading skills, bullying and victimization across the transition from elementary to middle school
2021
Students with poor reading skills and reading difficulties (RDs) are at elevated risk for bullying involvement in elementary school, but it is not known whether they are at risk also later in adolescence. This study investigated the longitudinal interplay between reading skills (fluency and comprehension), victimization, and bullying across the transition from elementary to middle school, controlling for externalizing and internalizing problems. The sample consists of 1,824 students (47.3% girls, T1 mean age was 12 years 9 months) from 150 Grade 6 classrooms, whose reading fluency and comprehension, self-reported victimization and bullying, and self-reported externalizing and internalizing …
Associations between self-efficacy, bullying and health-related quality of life in a school sample of adolescents: a cross-sectional study
2018
Background To better understand health-related quality of life (HRQOL) in adolescents, it is important to gain knowledge about factors associated with HRQOL. Being involved in bullying is a significant threat to health, and social and psychological well-being; further, such problems can last into adulthood. The aim of this study was to explore the role of general self-efficacy (GSE) and bullying in relation to HRQOL. We specifically sought to study the prevalence of bullying, as well as the associations between both bullying and self-efficacy and HRQOL in a sample of adolescents. Methods This was a cross-sectional study of 723 adolescents (12–18 years) attending schools selected using rando…
Computer-assisted sperm morphometry fluorescence-based analysis has potential to determine progeny sex
2016
This study was designed to determine the ability of computer-assisted sperm morphometry analysis (CASA-Morph) with fluorescence to discriminate between spermatozoa carrying different sex chromosomes from the nuclear morphometrics generated and different statistical procedures in the bovine species. The study was divided into two experiments. The first was to study the morphometric differences between X- and Y-chromosome-bearing spermatozoa (SX and SY, respectively). Spermatozoa from eight bulls were processed to assess simultaneously the sex chromosome by FISH and sperm morphometry by fluorescence-based CASA-Morph. SX cells were larger than SY cells on average (P < 0.001) although with impo…
Morphometry and subpopulation structure of Holstein bull spermatozoa: variations in ejaculates and cryopreservation straws
2016
Artículo científico Sperm quality is evaluated for the calculation of sperm dosage in artificial reproductive programs. The most common parameter used is motility, but morphology has a higher potential as a predictor of genetic quality. Morphometry calculations from CASA‑Morph technology improve morphological evaluation and allow mathematical approaches to the problem. Semen from 28 Holstein bulls was collected by artificial vagina, and several ejaculates were studied. After general evaluation, samples were diluted, packaged in 0.25 ml straws, and stored in liquid nitrogen. Two straws per sample were thawed, and slides were processed and stained with Diff‑Quik. Samples were analyzed by a CA…

Combined effects of type and depth of counting chamber, and rateof image frame capture, on bull sperm motility and kinematics
2019
Semen quality assessment requires accurate, reliable and objective methods for examination of sperm variables including sperm motility. For preparation of semen samples for artificial insemination, as a genetic resource, samples that are used for insemination need to have the capacity to result in a highly acceptable fertility rate. Several methods have been developed for evaluation of bull sperm in laboratory conditions and for preparation of doses for artificial insemination. Computer-assisted semen analyses can provide objective information on various sperm variables. Nevertheless, this equipment requires fine-calibrations considering differences among species, breeds and conditions for …
Bullying, defending, and outsider behaviors: The moderating role of social status and gender in their relationship with empathy
2018
The aim of the present study was to examine whether the effect of empathy on the role children play in bullying situations, as either bullies, defenders or outsiders, was moderated by children's social status within their classroom, and whether this moderation was gender dependent. For this purpose, we used a representative sample of 2,050 Spanish primary school children (50.80% girls) from grades 3-6 (Mage = 9.80 years; SD = 1.24), recruited from 27 primary schools. Results showed that the effect of empathy on bullying behavior was moderated by the sociometric rating only in girls. Both empathy and social rating had an effect on defending behavior. However, neither the children's sociometr…
Cyberbullying a modern form of bullying: Let's talk about this health and social problem
2018
Abstract Cyberbullying or electronic aggression has already been designated as a serious public health threat. Cyberbullying should also be considered as a cause for new onset psychological symptoms, somatic symptoms of unclear etiology or a drop in academic performance. Pediatricians should be trained to play a major role in caring for and supporting the social and developmental well-being of children.
CLINICAL AND LABORATORY FINDINGS OF BOUTONNEUSE FEVER IN SICILIAN CHILDREN
1998
The spectrum of signs and symptoms of 645 consecutive children diagnosed from 1984 to 1996 with boutonneuse fever (BF), a mild rickettsial disease caused by Rickettsia conorii endemic in the Mediterranean basin, are reported. The major clinical features were fever (97.2%), exanthema (96.1%) and “tache noire” (71.8%). The large series examined permitted the authors to observe some rare or disregarded clinical features of the disease: cases with papulovesicular exanthema, reported previously only in adults who had been infected by R. conorii in Africa; and cases in which the only symptom was an isolated lymphadenopathy. Conclusion R. conorii infection should be considered in patients with lym…
