The presence of the internal carotid artery (ICA) near tonsils can also cause severe bleeding during a tonsillectomy. We investigated the relationship between tonsil width and volume; and superior, middle and inferior tonsil-ICA distances in 5-9 and 10-15 years of age children.

Cranial MRI images of 200 children between 5 and 15 years of age were evaluated retrospectively. There were 100 children in group 1 (5-9 years of age) and 100 children in group 2 (10-15 years of age). Palatine tonsil width and volume; and superior, middle and inferior tonsil-internal carotid artery (ICA) measurements were performed bilaterally.

Our results showed that bilateral tonsil width and volume; and left superior, middle and inferior tonsil-ICA distance of 5-9 years of age group were lower than those of the 10-15 year-of age group (p<0.05). The nearest distance between ICA and palatine tonsil is at the inferior tonsil-ICA distance side in both age groups. Especially mean inferior and middle tonsil-ICA distances were lowand inferior tonsillary fossa, maximum attention must be performed for the possibility of the ICA being very closer to the tonsil to avoid unwanted bleedings.
To determine if clinical history and radiographic findings are reliable predictors for coin versus button battery in children presenting with esophageal foreign bodies to accurately guide decision making regarding the urgency of removal.

A retrospective chart review was conducted in a single pediatric tertiary care center of all children who presented with suspected coin or button battery esophageal foreign body ingestion from 2017 to 2019. Patients with documented surgical removal, completed consultation notes, and available radiographic studies were included. Descriptive statistical analysis was performed and predictive characteristics of the diagnostic tests were calculated.

139 patients met inclusion criteria for the study. Of 5 patients who had esophageal button batteries removed, clinical history was concerning for button battery in 2; accuracy of 12.35%. However, radiology reports suggested a battery in all 5. The negative predictive value for radiology alone for diagnosis of button battery was 9tive removal. This could allow children to complete a period of observation at home, thereby reducing prolonged in-house wait times prior to operative removal.
The diagnosis of obstructive sleep apnea (OSA) is routinely based on just a single night's sleep examination. The night-to-night variability in children and adolescents has previously been investigated using type 4 sleep monitors or PSG. However, there is a lack of studies investigating the night-to-night variability when using type 3 sleep monitors. Therefore, the main purpose was to investigate the night-to-night variability in respiratory parameters in children and adolescents using a portable type 3 monitor. Furthermore, the purpose was to investigate the clinical relevance of night-to-night variability.

The study population was recruited from an ongoing research project concerning the effect of weight loss in children and adolescents with OSA and overweight/obesity. The inclusion criterion was the successful recording of two consecutive nights of sleep. Sleep examinations were recorded at home using the Nox T3 device and then blindly scored by the same registered polysomnographic technologist. To comin both diagnosis and severity of OSA from night to night. We therefore suggest the presence of a clinically relevant night-to-night variability which should be taken into account when diagnosing pediatric OSA.
AHI measurements varied widely between nights in some children and adolescents leading to frequent changes in both diagnosis and severity of OSA from night to night. learn more We therefore suggest the presence of a clinically relevant night-to-night variability which should be taken into account when diagnosing pediatric OSA.
To evaluate temporal skin thicknesses and stiffness values using shear wave elastography (SWE) in asymptomatic pediatric patients who underwent cochlear implantation.

Sixty-four deafened pediatric patients with unilateral cochlear implant (CI) who had no complications were enrolled. The age, sex, weight, height, body mass index (BMI), CI side, duration of CI use and CI device brand of all participants were noted. Temporal skin thickness and stiffness values were measured from implanted and contralateral unimplanted sides using SWE.

The mean skin thickness measurements of implanted and unimplanted sides were 11.87±3.42 and 5.34±1.56mm, respectively. The mean skin stiffness measurements of implanted and unimplanted sides were 3.08±0.7 and 1.29±0.26m/s, respectively. There were statistically significant differences in skin thickness and stiffness between implanted and unimplanted sides (P<.001, P<.001). The mean skin thickness and stiffness measurements did not differ among types of CI devices (P=.948, P=.362). Age had positive correlation with implanted (P<.001, P=.019) and unimplanted sides (P<.001, P<.001) skin thickness and stiffness. BMI had positive correlation with implanted (P<.001, P=.023) and unimplanted sides (P<.001, P<.001) skin thickness and stiffness. Duration of CI use had positive correlation with implanted side skin thickness (P<.001) and stiffness (P=.031).

Temporal skin thickness and stiffness increase after CI surgery. SWE has the potential to improve diagnostic accuracy, and our results may provide important data for evaluation of clinical entities that affect temporal skin structures.

They are highly dynamic channels, opening or closing in response to physiological and developmental stimuli or environmental challenges such as biotic and abiotic stresses. Accumulating evidence supports the idea that such dynamic controls occur through integrative cellular mechanisms. Currently, a few fluorescence-based methods are available that allow monitoring changes in molecular movement through plasmodesmata. In this chapter, following a brief introduction to those methods, we provide a detailed step-by-step protocol for the Drop-ANd-See (DANS) assay, which is advantageous when it is desirable to measure plasmodesmal permeability non-invasively, in situ and in real-time. We discuss the experimental conditions one should consider to produce reliable and reproducible DANS results along with troubleshooting ideas.
