Pupil dynamics can represent an indirect measure of perception; thus, it has been broadly explored in the auditory and visual fields. Although it is crucial for experiencing the outside world, ...tactile perception is not well-explored. Considering that, we sought to answer the following question via a systematic review: does normal tactile perception processing modulate pupil dilation in mammals (human or not)? The review process was conducted according to PRISMA Statement. We searched on Periódicos CAPES (Brazil) for the following terms: (touch) OR (cutaneous stimulation) OR (tactile perception) OR (somatosensory) AND (pupil OR pupillary) NOT blind NOT reflex NOT pain NOT fear NOT noxious NOT autism NOT nerve NOT (pupillary block) NOT glaucoma NOT cataract NOT aneurysm NOT syndrome NOT treatment NOT special education. From the 6,488 papers found, 4,568 were duplicates, and nine fulfilled the inclusion criteria. All papers found a positive relationship between pupil diameter and tactile perception. We found that the pupil is a reliable indirect measure of brain states and can evaluate norepinephrine (NE)/locus coeruleus (LC) action, stimulus inhibition, arousal, cognitive processes, and affection independently of the stimuli category (visual, auditory, or tactile). We also found that the perceptual tactile processing occurs in similar ways as the other perceptual modalities. We verified that more studies should be done, mostly avoiding low sampling rate recording systems, confounders as cue signs, not automated stimulation, and concurrent stimulus and using more reliable equipment.
To correlate the nasal anatomical characteristics of newborns with the dimensions of short binasal prongs.
Observational, cross-sectional study carried out in two hospitals in southern Brazil. The ...authors evaluated 1620 newborns with neonatal data and nasal dimensions. To measure the dimensions of the nasal region, the authors considered the width of the medial columella, the right nostril diameter, and the left nostril diameter. These data were correlated with the dimensions of two models of short binasal prongs.
Of the total newborns evaluated, 807 were female (49.8%), and 813 were male (50.2%). The majority were white (96.2%). The mean gestational age was 37.4 ± 2.9 weeks, ranging from 22 to 42 weeks. The birth weight was 2946.8 ± 699.3 g, ranging from 490.0 to 4740.0 g. Most of the nasal measures were significantly larger than both prong model measurements.
The sizes of short binasal prongs available on the Brazilian market do not match the nasal anatomical characteristics of newborns.

Low- to high-energy impact trauma may cause from small fissures up to extended bone losses, which can be classified as closed or opened injuries (when they are visible at a naked eye).
The aim of ...this study was to investigate the feasibility of clinical diagnosis of bone trauma through medical infrared thermography, in a hospital emergency room.
Forty-five patients with suspected diagnosis of bone fracture were evaluated by means of medical infrared images, and the data correlated with the gold standard radiographic images, in the anteroposterior, lateral, and oblique views, at the orthopedic emergency department. The control group consisted of thermal images of the contralateral reference limb of the volunteers themselves. Data were acquired with a medical grade infrared camera in the regions of interest (ROIs) of leg, hand, forearm, clavicle, foot, and ankle.
In all patients evaluated with a diagnosis of bone fracture, the mean temperature of the affected limb showed a positive difference greater than 0.9 °C (towards the contralateral), indicating the exact location of the bone trauma according, while the areas diagnosed with reduced blood supply, showed a mean temperature with a negative variation.
Clinical evaluation using infrared imaging indicates a high applicability potential as a tool to support quick diagnosis of bone fractures in patients with acute orthopedic trauma in an emergency medical setting. The thermal results showed important physiological data related to vascularization of the bone fracture and areas adjacent to the trauma well correlated to radiographic examinations.

The present study aimed to evaluate the effects of hydrotherapy and tactile-kinesthetic stimulation on the birth weight of preterm infants admitted in the Neonatal Intensive Care Unit.
It was a ...randomized controlled trial, without blinding, in which 44 preterm infants of both sexes with gestational age between 32 and 34 weeks were included into two groups: hydrotherapy group (n = = 22) and tactile-kinesthetic stimulation group (n = 22). Weight gain was the parameter assessed daily.
In the tactile-kinesthetic stimulation group there was a variation in weight gain, but without significant difference (p = 0,43). However, in the hydrotherapy group, it was observed that increased weight gain started from the 2nd day (p < 0,001).
Hydrotherapy group presented significantly increased weight after the interventions, indicating that this technique can interfere with weight gain in preterm infants.
Crianças e adolescentes com paralisia cerebral e privados de comunicação efetiva podem também ter seu desenvolvimento intelectual dificultado. O objetivo desta pesquisa foi avaliar o desenvolvimento ...intelectual de crianças e adolescentes com paralisia cerebral e necessidades complexas de comunicação em uma escola especial no Brasil, baseado no uso de comunicação alternativa e ampliada (CAA). Quinze indivíduos com paralisia cerebral (idade média: 11a3m ± 2a9m) foram avaliados: 9 usavam CAA (seis meninos, 11a9m ± 3a4m) e seis não usavam (3 meninos, 10a6m ± 1a6m). As Matrizes Progressivas Coloridas de Raven – Escala Especial (CPM) foram usadas para a avaliação intelectual. Os que utilizavam a CAA obtiveram uma média de 25.89, os que não usavam 5.83 (p=0.012). Os resultados indicam que nesse coorte existe uma diferença significativa entre o desenvolvimento intelectual dos que usam CAA e dos que não a usam.
ABSTRACT Objectives: to analyze the ergonomics of two models of breastfeeding bras. Methods: descriptive study carried out with 152 infants in a Brazilian university hospital. The prototypes were ...separated into two groups (A and B). To compare the two bra models, the Odds Ratio (OR) was used as a measure of the strength of the association. In subjective perceptions, the Modified Borg Scale, and the chi-square test of independence (χ2) were used. To compare the two prototypes, the Z test and logistic regression analysis were performed. A significance level of 5% was considered. Results: the bra in group B was more suitable for ergonomics of physical and psycho-aesthetic comfort than the bra in group A (p < 0.0001), according to the logistic regression tests. Conclusions: modeling B was ergonomically adequate, with usability and evaluation criteria centered on breastfeeding women.

To assess the incidence of nasal injury in newborns submitted to non-invasive ventilation (NIV) via binasal prongs, to identify risks that come with using this interface, and to present actions for ...nasal injury prevention.
Observational and descriptive study performed in neonatal intensive care unit (NICU) of a public hospital in the south of Brazil. This research was divided into three stages. In the first one, nasal injury incidence was assessed in 148 newborns, using data collection from medical records. In the second stage, injury incidence, severity and a preliminary analysis of risks associated with the prescription of binasal prongs were analyzed in 33 newborns who required NIV. In the third stage. recommendations were presented to prevent nasal injury during NIV with short binasal prong.
The incidence of nasal injury in the first stage was 37.16%, and 63.64% in the second one. As for severity, 68.42% of the injuries showed Stage I severity, and 31.58% Stage II. The main risks associated with the use of binasal prongs were inappropriate prong size, inappropriate prong model, interface reuse, prolonged NIV use exclusively with binasal prongs, incorrect prong position and NIV circuit pulled. A total of 17 preventive approaches were recommended: 13 related to newborns care and not dependent on prior investment. Among them: to choose appropriate prong size; to keep the prong and the NIV circuit well positioned and periodically massages with circular movements in the nasal septum and columella.
The inappropriate prong size, interface reuse, prong model, prolonged NIV use with binasal prong and incorrect prong and NIV circuit position may be associated with the high occurrence of injury in the NICU studied. Simple approaches concerning clinical staff care actions towards the newborn in NIV, which do not require a financial investment, can prevent nasal injury.
Objective: to analyze puerperal breast temperature using infrared thermography. Method: study performed at the Human Milk Bank of a Hospital in Curitiba, Brazil. A lactating mother with bilateral ...engorgement in the external breast quadrants was randomly selected and the temperature was measured.Results: A soft mammary lobe was found, with thermal asymmetry of 1.5ºC, compared to the contralateral region, however no thermal asymmetry was identified in the general temperature between the breasts. Conclusion: this case suggests that thermal asymmetry in the puerperal breast is related to the volume of milk in the lobes and not to dysfunctions or pathologies in these lobes. The study indicates possibilities for deepening the understanding of lactational physiology with the amplification of the sample group evaluated in this study. Thermography is a technique suitable for lactating mothers, however requires an appropriate room, time for acclimatization and knowledge of the mammary anatomy.
To compare the effectiveness of the hydrocolloid and the silicone gel on the nasal protection of the newborns (NBs) during the use of noninvasive ventilation (NIV).
Thirty-three NBs were selected. ...They were randomly divided into three groups of 11 NBs, according to the type of nasal protection used: hydrocolloid, thick silicone gel, and thin silicone gel. The stage of the nasal injury and need for exchanging nasal protection were assessed before the connection to the NIV and every 24 h until the physician's authorization for NIV's suspension.
The mean gestational age was 32.03 ± 3.93 weeks, and the median birth weight was 1760 g (750–3535 g). The incidence of nasal injury using hydrocolloid, thick silicone gel, and a thin silicone gel group was 36.36%, 81.81%, and 72.72%, respectively (p = 0.06). Regarding the injury stage, there was no statistical significance between the three study groups. The hydrocolloid protection type had the best adhesion (p = 0.03) on the NBs' skin.
Although this study was conducted by local practice patterns, the results showed that the hydrocolloid could be the best choice to prevent the nasal septum base injury in the NB submitted to NIV.
