Background: The aim of the study was to present a case of mixed olfactory neuroblastoma (ONB) and carcinoma, an extremely rare tumor with only a few cases in the published literature.
Case Description: An otherwise healthy 27-year-old male presented with sinus complaints, headache, and unilateral eye discharge. Imaging and endoscopy revealed a mass presumed to represent a juvenile nasopharyngeal angiofibroma. Unexpectedly, the final pathology report revealed high grade mixed ONB and carcinoma. This tumor is the sixth and youngest documented patient with mixed ONB and carcinoma.
Conclusion: Physicians should remain vigilant for the possibility of malignancy in their approach to nasal cavity masses, even in young otherwise healthy patients. Careful review of the immunohistopathology should also be taken, as mixed olfactory tumors such as these are aggressive, rare entities that require multidisciplinary oncologic care.

The olfactory sensory system plays vital roles in daily activities, such as locating mate partners, foraging, and risk avoidance. Natural enemies can locate their prey through characteristic volatiles. However, little is known about whether prey can recognize the volatiles of their predators and if this recognition can increase the efficiency of prey escaping from predators.
View Article and Find Full Text PDFOlfaction can aid individuals in finding genetically compatible mates in many animals, while high levels of mixed paternity may result from a limited ability to evaluate their mate's genetic profile against their own before mating. To test this suggestion and explore if olfaction may indeed influence mating patterns in birds, we combined published measures of olfactory ability with data on genetic mating pattern in the same species, across a phylogenetically broad range of species. We used three measures of olfaction: (1) olfactory bulb diameter, (2) olfactory bulb volume and (3) number of olfactory receptor genes (148, 134 and 48 species, respectively).

Background: Evidence-based medicine and patient-reported outcome measures (PROMs) are helpful tools in the wound care field, but few studies correlating quality of life (QoL) changes with objective changes exist.
Objective: To investigate the QoL changes following the shift from primary dressings alone to elastic compression bandages in patients with a new diagnosis of vascular skin ulcer, and to evaluate a possible correlation between objective and subjective changes.
Materials And Methods: This study included 122 patients with a new diagnosis of vascular skin ulcer, who had previously used only primary dressings alone.

Objective: The aim of this study was to determine the prevalence and trajectory of persistent symptoms following COVID-19 and to investigate factors influencing these among employees in the health and welfare services in Germany.
Methods: This exploratory, mixed retro- and prospective cohort study using paper-and-pencil questionnaires was conducted among insured persons of the German Social Accident Insurance Institution for the health and welfare services with a SARS-CoV-2 infection in 2020. The baseline survey in February 2021 was succeeded by two follow-up surveys after 8 and 13 months.

Article Synopsis
- - The AMBORA trial showed the benefits of a pharmacological care program for adults using oral antitumour therapeutics (OAT), but similar tailored support for pediatric patients was lacking, leading to the development of the youngAMBORA program.
- - This program was designed using both quantitative data on the types of cancers and OAT used in a pediatric cancer center, and qualitative surveys to gauge the needs of patients, caregivers, and healthcare providers regarding medication application and side effects.
- - Key findings revealed that leukemia is common among pediatric patients, with many expressing a desire for education about oral medication; the program will provide counseling, child-friendly medication support, and evaluate 17 relevant side effects, including some previously unrecognized. *
