Objective: Foreign bodies (FB) of the ear and nose are common findings in the pediatric population. The objective of this project is to present our experience of cases presented to our department and to correlate the insertion of the FB in relation to the child's handedness.
Methods: This project was carried out at the Department of Otorhinolaryngology Head and Neck Surgery of "Aghia Sophia" Children's Hospital (Athens, Greece), between December 2007 and August 2008. Data collected includes age and sex of the child, time elapsed between the insertion of the FB and its removal, type of FB, site of insertion, description of the child's handedness, conditions of removal and complications.
Results: 46 FB were removed from the nasal cavities. On the right nasal cavity, 29/31 (93.55%) children were right handed and 2/31 (6.45%) were left handed. On the left nasal cavity, 11/14 (78.57%) were right handed and 3/14 (21.43%) children were left handed. One right handed child had a FB in both nasal cavities. 44 FB were removed from the ear (external auditory canal: EAC), 30 (68.18%) from the right EAC and 14 (31.82%) from the left. On the right EAC, 28/30 (93.33%) children were right handed and 2/30 (6.67%) were left handed. Children with FB of the left EAC were 9/14 (64.29%) right handed and 5/14 (35.71%) left handed.
Conclusions: Children insert FB into their nasal cavities randomly (P=0.308). As a result, there is no correlation with the child's handedness and right/left nasal cavities FB insertion. On the other hand, children do insert FB into their right/left EAC according whether they are right/left handed (P=0.014). Consequently, right handed children insert FB into their right EAC and left handed children into their left EAC.

Helical structures such as right-handed double helix for DNA and left-handed α-helix for proteins in biological systems are inherently chiral. Importantly, chirality at the nanoscopic level plays a vital role in their macroscopic chiral functionalities. In order to mimic the structures and functions of natural chiral nanoarchitectures, a variety of chiral nanostructures obtained from artificial helical polymers are prepared, which can be directly observed by atomic force microscopy (AFM), scanning tunneling microscopy (STM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM).

Previous reports of CBS-LBD describe patients with diffuse LBD, a younger age of onset and occasionally lacking core features like REM sleep Behavior Disorder (RBD).
Method: We present a young patient with CBS who had a rapid progression and was found to have a high burden of limbic LBD and high AD co-pathology at autopsy.

Background: Many patients present to our clinic with primarily executive rather than amnestic impairments. Recently, Townley and colleagues proposed criteria for a progressive dysexecutive syndrome (PDS). To date, PDS has been reported to be more common in younger individuals (55-65 years old) and is associated with Alzheimer's biomarkers (AD).

Cast films of racemic helicene derivatives adsorbed onto the surface of nanometric silica helices with controlled handedness exhibited distinct CD signals, whereas no CD signal was observed in the absence of silica nanohelices. These CD signals originate from the helical supramolecular assemblies formed by the racemic mixture of helicenes, with no evidence of enantiospecific adsorption. Interestingly, when enantiomerically pure forms of these helicenes were drop-cast onto the silica helices, different CD spectra were observed depending on the combination of the helicenes' handedness with that of the silica nanohelices.

Article Synopsis
- The study presents a method for creating twisted helical cellulose nanocrystal films using 3D printing, achieving unique optical properties.
- The films exhibit high transparency and dual circular polarization, with different types depending on the printing orientation.
- These materials have potential applications in photonics, thermal management, and energy efficiency due to their ability to manipulate light in the near-infrared region.
