background: The aim of this study was to evaluate the clinical and epidemiological characteristics of patients with acute intoxication admitted to the Intensive Care Unit (ICU). material and methods: An observational retrospective study was conducted on intoxicated patients who admitted to ICU between January 2022 and January 2024. Data were collected from the patients medical records. The demographic characteristics, causes of intoxications, clinical parameters, the mean stay in the ICU, treatment modalities and prognosis were recorded. Results: A total of 2875 critically ill patients were admitted during the study period, and 109 (3.79%) of them were acute intoxications. Their mean of ages was 38.09 ± 12.29. The female-to-male ratio was 1.37/1. Drugs were found to be the primary cause (62.39%) of intoxications, and analgesics, antidepressants, and antibiotics were the most frequent agents. Suicidal attempts were present in 66 patients, most of them were female (62.13%) and between 17 - 24 years (40.91%). The other common causes of intoxications were carbon monoxide (CO) (22.02%), methyl/ethyl alcohol (8.26%) and mushroom (5.50%). The mean stay in the ICU was 2.69 ± 0.89 days. mechanical ventilation was applied to 10 of our patients. Renal replacement therapy was required in 6 patients. Despite all treatments, 6 of our patients died, and we found the mortality rate to be 5.50%. Conclusion: Intoxications were more frequent in young female patients and drugs were the most common cause with suicidal intent. Unfortunately, CO poisoning continues to be a very important problem in our city. These findings provided significant information about the characteristics of intoxications in Karabuk.

Development and Optimization of Universal bone Conduction Hearing Spectacles

International Journal of Otolaryngology and Head & Neck Surgery 2024年第5期13卷 344-358页

作者： Johannes burkart mona Kirstin Fehling Saadu Adamu raúl Pérez ramos Daniel Häussler Department of Otorhinolaryngology Head and Neck Surgery University Hospital Mannheim Mannheim Germany National Ear Care Centre Kaduna Nigeria School of Advanced Education Research and Accreditation University Isabel I Castelln de la Plana Spain

background: Non-implantable bone anchored hearing devices (bCHDs) are utilized for patients with conductive or mixed hearing loss who are unsuitable for conventional hearing aids or have unresolved middle ear issues. These devices can be surgically implanted or attached using adhesive plates, dental sticks, elastic headbands, or bone conduction spectacles. Optimal fitting of bone conduction spectacles requires appropriate frame selection and contact pressure in the temporal and mastoid areas. The ANSI S3.6 and DIN EN ISO 389-3 standards recommend a contact area of approximately 1.75 cm2 and a maximum force of 5.4 N for effective sound transmission and comfort. methods: This study aimed to evaluate the technical fit and mechanical stability of universal bone conduction hearing spectacles compared to established systems. A Sen-Pressure 02 thin-film sensor connected to an Arduino Uno R3 board measured contact force in the temporal and mastoid areas. Several bCHDs were tested, including the bruckhoff la belle bC D50/70, radioear b71 headset, radioear b71 elastic headband, Cochlear baha SoundArc m, and Cochlear baha elastic headband, on a PVC artificial head, with data analyzed using ANOVA and LSD post hoc tests. Results: The la belle bC D50/70 spectacles showed comparable contact force to established bCHDs, ensuring adequate sound transmission and comfort. Significant differences were observed between the systems, with the radioear b71 headset exhibiting the highest forces. The la belle bC D50/70 had similar forces to the radioear b71 elastic headband. Conclusion: The la belle bC D50/70 universal bone conduction hearing spectacles are a technically equivalent alternative to established bCHDs, maintaining pressure below 5.4 N. Future research should explore the impact of different contact forces on performance and comfort, and the integration of force control in modified spectacles. This study indicates that the la belle bC D50/70 is a viable alternative that meets audio
