In the present cross-sectional experimental study we investigated infants’ early ability to intermodally detect numerosity of visual-auditory object-like and social stimuli. We assumed that presentation of face – voice stimuli would distract infants’ attention from detection of numerical invariant. Seventy-eight infants (aged 5, 7 and 9 months) participated in four experimental Conditions (simultaneously projected pairs of identical objects, non-identical objects, objects projected together with familiar face and objects projected together with unfamiliar face). Visual stimuli in each trial varied in numerosity (1 -2 / 1-3 / 2 -3) and they were accompanied by piano sounds or voice sounds also varying in numerosity (one, two or three sounds in La tonality). By means of preferential looking technique, we measured infants’ fixation of attention to the visual stimulus that numerically matched with the sound. When object-like stimuli were projected, infants –except 5-month-old boys –tended to intermodally detect numerical invariant. Shape similarity of the objects facilitated infants’ intermodal detection of numerosity. When socially salient stimuli were co-presented with object-like stimuli, infants preferred to look at the face, ignoring numerosity of the auditory stimulus. Nor sound quality (piano vs. voice) neither familiarity of the face (mother’s face vs. stranger woman’s face) affected infants’ perception. Although intermodal detection of perceptual cues is a primary function of both face and number perception, each one of these perceptual systems seems to follow a different developmental path.

In this study, the effects of an experimental-induced provocation on emotions and aggression were examined in 34 aggressive conduct-disordered children using a competitive reaction time paradigm. Two experimental conditions were created, an increasing provocation and a low constant provocation condition. Self-rated anger was assessed directly after provocation on a 5-point-visual scale. In addition, negative and positive emotions as well as physiological measures (heart rate and skin conductance level) were measured at baseline and after provocation. Results revealed that participants’ aggressive behaviour and subjective emotions differed as a function of the opponent’s level of provocation. Concerning physiological parameters, no significant differences were found between the experimental conditions. These results suggest that affective, but not physiological variables characterize reactive aggression in conduct-disordered children.

Background: Pigmented tumour of the skin is one of the common tumour in human including the benign pigmented tumours (more common) called Nevi tumours and the malignant one called melanoma which was less frequent but the most poor in prognosis. In addition, the others not belonging to these group had the same clinical appearance, so the application of histopathology and immunohistochemistry for the definitive diagnosis was indespensible. Objectives: 1. To describe the macroscopic features of the pigmented tumoral-like lesions; 2. To classify the histopathologic types of the pigmented cell tumours and the other pigmented tumours of the skin. Materials and Method: Cross-sectional research on 55 patients diagnosed as pigmented tumoral lesions by clinician, then all definitively diagnosed by histopathology combining the immunohistochemistry in difficult cases. Results: There was no difference in gender, the disease was discovered most common in adult, especially with the age over 51 years old (58.1%). the most region located was in the face accounting for 60%, following the trunk and limbs (14.6%, 12.8% respectively). All 3 malignant melanomas happened in foot. The most common color of the lesions was black (65.4%), the other ones were rose, grey and blue. Histopathology and immunohisthochemistry showed that the true pigmented cell tumours were 52.6% encompassing benign ones (Nevi tumour) (41.8%), melanoma (5.4%) and lentigo (5.4%). 47.4% was not the true pigmented cell tumour including pigmented basocellular carcinoma (36.4%) and the others less common as histiofibromas, acanthoma and papilloma. Conclusion: the pigmented tumoral-like lesions of the skin could be the true pigmented cell tumours and the others, so the application of the histopathology and the immunohistochemistry after the clinical discovery helps to determine and classify the disease definitely and for the best orientation of treatment as well. Key words: skin tumour, benign pigmented tumour (Nevi), malignant pigmented tumour (melanoma), pigmented basocellular carcinoma

Objective: This study aimed to analyze the presence of lesions in the skull and face and the associated factors in pedestrian victims of traffic accidents. Methods: A cross-sectional, descriptive-analytical study carried out through the analysis of medical records of pedestrian victims of traffic accidents in an emergency service in the city of Campina Grande, Brazil, during the year of 2016. Information was collected regarding gender, age group, day of the week, time of the accident, type of vehicle involved, presence of trauma to the skull and face, and outcomes. The Chi-square and Fisher's Exact tests were used, with a significance level of 5%. Results: A total of 1,884 medical records were evaluated, out of which 7.1% (n = 133) involved pedestrians. Men were the most frequent victims (68.4%), and victims of age 60 years old or over (30.5%) predominated. Almost one-third of the cases were recorded during the weekends (30.5%), and the most prevalent time was at night (52.7%). Regarding the type of vehicle involved, motorcycles predominated (47.4%). Head trauma was present in 37.6% of victims, while facial injuries corresponded to 8.2%. In 12% of cases, the victims died. The variables of gender, age group, occurrence on weekends, and trauma to the face showed a statistically significant association with the occurrence of traffic accidents (Chi-square test; p<0.05). Conclusion: Among pedestrian victims of traffic accidents, there is a predominance of men aged 65 years or over. Accidents are frequent at night, and motorcycles are the main vehicles involved. The presence of trauma to the skull and face regions is high.

AbstractBackgroundAesthetic alterations in the face can be self-perceived and can affect quality of life in young adults.ObjectiveTo assess the impact of malocclusion on self- perceived oro-facial behaviour among young adults.MethodsA Cross sectional study was conducted among 638 young adults (aged 18–21 years) of Hyderabad city. One college from each of the five zones of the Hyderabad city (five colleges) were selected by simple random sampling procedure. A 21-item Oro-facial investment scale (OFIS) questionnaire assessing self-perceived oral health knowledge, attitude, practice and Dental Aesthetic Index (DAI) assessing the severity of malocclusion was used. Data were analysed with standard statistical software (SPSS, Statistical package for the social sciences, version 20.0). p < 0.05 was considered statistically significant.ResultsMales had higher mean scores for knowledge (2.90 ± 0.49) than females (2.73 ± 0.82) and was statistically significant (p = 0.002*). No statistically significant gender differences were found in relation to attitude and practice. Analysis of variance (ANOVA) showed that there was a significant difference in all the three scores (knowledge, attitude, practice) with respect to age, with significantly high score for knowledge and practice among 18 year old subjects (p = 0.0001*; p = 0.0003* respectively) and attitude among 21 year old subjects (p = 0.0049*). No statistically significant age, gender differences were found in relation to DAI scores. Upon correlation, DAI significantly and positively correlated with knowledge (p = 0.03*) and attitude (p = 0.0001*).ConclusionThis study has shown significant impact of malocclusion on the self-perceived oro-facial behaviour.

Relevant personal protective measures during the COVID-19 pandemic include face masks, possibly decreasing the risk of infection among the general population and healthcare workers (HCW) if utilized properly. The aim of the study was to assess whether different Polish HCW utilize face masks according to the 2020 World Health Organization guidance (WHO) criteria. This cross-sectional study included 1156 respondents who participated in an internet survey evaluating mask-related behaviors. All the WHO criteria were complied with by 1.4% of participants, regardless of medical profession, specialty or place of employment. HCW mostly adhered to criterion 1 (C1; strict covering of the face and mouth with the mask; 90.8%), C4 (washing/disinfecting the hands after touching/taking off the mask; 49%) and C3 (taking off the mask properly without touching the anterior surface; 43.4%), whereas C2 (avoidance of touching the mask with hands) was complied with least commonly (6.8%). HCW with mask-induced itch (31.6%) complied to C2 less often (odds ratio 0.53; p = 0.01). The study reveals that Polish HCW rarely adhere to all the 2020 WHO guidance criteria on the use of masks, whereas the adherence to particular criteria is variable and may be associated with the presence of skin-related conditions and other factors. Better compliance with the recommendations in the future is necessary to increase personal safety of HCW and prevent the transmission of SARS-CoV-2.

Background: Legal assisted dying is a rare event, but as legalisation expands, requests for it will likely increase, and the nurse most often receives the informal, initial request. Objectives: To assess the effects of attitude in interaction with normative and control beliefs on an intention to respond to a request for legal assisted dying. Ethical considerations: The study had the lead author’s institutional ethics approval, and participants were informed that participation was both anonymous and voluntary. Methodology: This was a cross-sectional correlational study of 377 Australian registered nurses who completed an online survey. Generalised linear modelling assessed the effects of independent variables against intended responses to requests for legal assisted dying. Results: Compared to nurses who did not support legal assisted dying, nurses who did had stronger beliefs in patient rights, perceived social expectations to refer the request and stronger control in that intention. Nurses who did not support legal assisted dying had stronger beliefs in ethics of duty to the patient and often held dual intentions to discuss the request with the patient but also held an intention to deflect the request to consideration of alternatives. Discussion: This study advances the international literature by developing quantified models explaining the complexity of nurses’ experiences with requests for an assisted death. Attitude was operationalised in interaction with other beliefs and was identified as the strongest influence on intentions, but significantly moderated by ethical norms. Conclusion: The complex of determinants of those intentions to respond to requests for an assisted death suggests they are not isolated from each other. Nurses might have distinct intentions, but they can also hold multiple intentions even when they prioritise one. These findings present opportunities to prepare nurses in a way that enhances moral resilience in the face of complex moral encounters.

Cultural Data

96 7- and 9-yr.-olds were under four experimental conditions. A “distinctive label” group ( n = 24) associated four different gender-cued labels with four infants' faces. An “equivalent label” group ( n = 24) associated only two of these labels. There were also two no-label groups ( ns =: 24), “differential perception” and “perception.” In the former, perceptual cues were provided; no cues were provided in the latter. The main measure was a test of perception. 9-yr.-olds were not affected by the labels, 7-yr.-olds were but more significantly so during initial trials. It is proposed that perception is affected by labels, learning, and selective attention. These effects are determined developmentally. As age increases the effects of verbal cues diminish and of perceptual cues increase. The findings are related to cross-cultural data, indicating that Israeli toddlers classify according to gender earlier than do American children. This is probably because Hebrew more than English contains distinctive linguistic cues related to sex.
