Cochlear nerve deficiency(CND) is a rare inner ear malformation characterized by a hypoplastic or absent cochlear nerve, resulting in variable hearing loss or total deafness, depending on the quantity of nerve fibers present. About 18% of congenital hearing loss are associated with CND. It is a disease of uncertain cause.

Dodecyl creatine ester (DCE) is a creatine prodrug currently developed for brain diseases, including creatine transporter deficiency (CTD), an incurable rare genetic disease. A dual strategy combining a prodrug to bypass the non-functional creatine transporter and its delivery via the nose-to-brain pathway has been proposed to replenish creatine levels in cerebral cells, particularly in neurons of CTD patients. In vitro and in vivo studies in various animal models, including wild-type non-human primates and creatine transporter deficient mice, show that formulated DCE, when administered intranasally, achieves significant cerebral distribution up to the target cells, the neurons, and modulates the expression of neuronal markers related to cognitive function at doses intended for patients.

Nose-to-brain delivery of lithium via a sprayable in situ-forming hydrogel composed of chelating starch nanoparticles.

J Control Release

December 2024

Department of Chemical Engineering, McMaster University, 1280 Main Street, West Hamilton, ON L8S 4L8, Canada. Electronic address:

While bipolar disorder patients can benefit from lithium therapy, high levels of lithium in the serum can induce undesirable systemic side effects. Intranasal (IN) lithium delivery offers a potential solution to this challenge given its potential to facilitate improved lithium transport to brain when delivered to the olfactory mucosa. Herein, a sprayable, in situ forming nanoparticle network hydrogel (NNH) based on Schiff base interactions between chelator-functionalized oxidized starch nanoparticles (SNPs) and carboxymethyl chitosan (CMCh) is reported that can be deployed within the nasal cavity to release ultra-small penetrative SNPs over time.

Currently, targeted biological therapy is an innovative and highly effective approach in the treatment of severe chronic rhinosinusitis with nasal polyps (CRSwNP) associated with T2 inflammation that is uncontrolled by standard treatment methods. The article presents the first experience of long-term observation of a patient who, one year after the start of targeted biological therapy with dupilumab, independently stopped the treatment due to complete relief of symptoms of CRSwNP, despite recommendations to continue therapy to maintain control. At the same time, one year after the refusal of biological therapy, the patient showed persistent clinical remission in relation to the symptoms of CRSwNP, confirmed by the results of videoendoscopic examination of the nasal cavity and computed tomography of the sinuses.

Uncommon Nasal Mass Presentation: A Radiological Case Series.

J Pers Med

December 2024

Radiological Sciences Section, Department of Biomedicine, Neuroscience and Advanced Diagnostics, University of Palermo, AOUP "Paolo Giaccone", Via del Vespro 129, 90127 Palermo, Italy.

Nasal and paranasal sinus masses can arise from a wide range of conditions, both benign and malignant, as well as congenital or acquired. Diagnosing these masses is often challenging, requiring a combination of nasal endoscopy, imaging studies, and histopathological analysis. Initial imaging frequently involves computed tomography or cone beam computed tomography (CBCT) to evaluate the bony anatomy of the nasal cavity and surrounding sinuses, while magnetic resonance imaging (MRI) is typically used for detailed assessment of soft tissues and to aid in differential diagnosis when the findings are inconclusive.
