Subjective Smell Disturbances in Children with Sars-Cov-2 or Other Viral Infections do not Correspond with Olfactory Test Results.

BACKGROUND: Olfactory dysfunction associated with SARS-CoV-2 infection in children has not been verified by a validated olfactory test. We aimed to determine whether these complaints are objectifiable (test-based hyposmia), how often they occur during acute SARS-CoV-2 infection compared to other upper respiratory tract infections (URTI), as well as in children recovered from COVID-19 compared to children with long COVID. METHODS: Olfactory testing (U-sniff test; hyposmia<8 points) and survey-based symptom assessments were performed in 434 children (5-17 years; 04/2021-06/2022). 186 symptom-free children served as controls. Of the children with symptoms of acute respiratory tract infection, SARS-CoV-2 PCR test results were positive in 45 and negative in 107 children (URTI group). Additionally, 96 children were recruited at least 4 weeks (17.6±15.2 weeks) after COVID-19, of whom 66 had recovered and 30 had developed long COVID. RESULTS: Compared to controls (2.7%), hyposmia frequency was increased in all other groups (11-17%, p<0.05), but no between-group differences were observed. Only 3/41 children with hyposmia reported complaints, whereas 13/16 children with complaints were normosmic, with the largest proportion being in the long-COVID group (23%, p<0.05). CONCLUSION: Questionnaires are unsuitable for assessing hyposmia frequency in children. Olfactory complaints and hyposmia are not specific for SARS-CoV-2 infection. The number of complaints in the long-COVID group could result from aversive olfactory perception, which is undetectable with the U-sniff test.

[Syphilis infection in the ENT area]. / Syphilisinfektion im HNO-Bereich.

The number of reported cases of syphilis has been increasing for years. The sexually transmitted disease is caused by the spirochete Treponema pallidum subspecies pallidum and progresses in different stages. Symptoms in the ENT area can occur in all stages. This means that a syphilis infection should always be considered by the ENT doctor as a differential diagnosis if the symptoms are suitable. Thus, with increasing oral sexual intercourse, the primary effect/hard chancre is more often observed in the oral cavity. In addition, symptoms can occur not only in the oral cavity, but also in the ear, nose, larynx, cervical and facial regions. The diagnosis is confirmed by direct pathogen detection or by serological detection. The spirochete cannot be cultivated. The therapeutic gold standard is the administration of benzathine penicillin G or procaine penicillin G. Doxycycline, macrolides or ceftriaxone are available as alternatives. In case of inner ear or cranial nerve involvement, the additional administration of a glucocorticoid is recommended. Before antibiotic therapy is administered, the patient must be informed about the possibility of a Jarisch-Herxheimer reaction. In cases of a syphilis infection, a collegial cooperation with the venereologists is always recommended so that an effective and comprehensive diagnosis and therapy can be carried out.

Pain in children undergoing tonsillotomy with alternating ibuprofen and paracetamol - a prospective observational study.

BACKGROUND: The optimal pain therapy for children undergoing tonsillotomy remains unknown. Our aim was to evaluate a standard pain therapy including the alternating application of ibuprofen and paracetamol. METHODS: Pain intensity of 81 in-patients after tonsillotomy aged 2-12 years was evaluated three times daily (mean observation 3.85 days) using the Children's and Infants' Postoperative Pain Scale (CHIPPS) in children <5 years, or with the Faces Pain Scale-Revised (FPS-R) in older children. Parents completed the Parents' Postoperative Pain Measure (PPPM-D) in addition. Exceeding the cut-off value in one of the scores implied the indication for an opioid rescue medication (RM). Endpoints were number of children with indication for the RM, course of pain, concordance between pain scales, and adverse events. RESULTS: Overall, 45.7% of children needed the RM either in the recovery room or on the ward. The rate of children having an indication for RM on the ward was 30.9%. The highest proportion of affected children was identified on the day of surgery (32.1%). Most indications were detected with the PPPM-D only. A comparison with an earlier study showed less affected children compared to ibuprofen monotherapy on the day of surgery and the first postoperative day. Eleven children (13.6%) developed fever. CONCLUSION: Although our pain therapy concept was effective from postoperative day 1 onwards, it needs improvement for the day of surgery. The overall concordance between the PPPM-D and CHIPPS or FPS-R was low. Fever might be a confounder for the pain intensity measurement with the PPPM-D.

Fast-track flipping: flipped classroom framework development with open-source H5P interactive tools.

BACKGROUND: The availability and popularity of laptops, tablet PCs and smartphones in private and work environments offers considerable potential for reasonably integrating blended learning formats into structured medical learning environments. The promising educational principle of the flipped classroom (FC) provides the opportunity to effectively combine e-learning and face-to-face teaching within a single framework. However, similar to most blended learning formats, the FC requires a solid groundwork of structured digitized learning content. As rearranging a whole curriculum is intense and time consuming, physicians occupied simultaneously in clinical practice and teaching may be confronted with a lack of time during this process. METHODS: We developed two straightforward approaches to transforming a pre-existing, lecture-based otolaryngology curriculum into interactive videos within a Moodle learning management system. Special attention was given to reducing individual working time for medical professionals. Thus, while one approach was mainly guided by a medical professional to control the content-related quality of video processing, we investigated an alternative approach outsourcing work to a technician. Afterwards, the working time was analysed and compared. The resulting videos were revised with the H5P plugin for moodle to adjust the content where necessary. RESULTS: We identified a fast-track approach for creating structured e-learning content suitable for flipped-classroom-based lectures, other blended learning formats, or even providing a whole curriculum online. The alternative approach significantly reduced working time for medical professionals but did not impair the content-related quality significantly. CONCLUSIONS: The use of H5P interactive tools via Moodle LMS provides a major procedural benefit by allowing the easy adjustment of pre-existing video material into suitable online content. Reasonably outsourcing work to technicians can significantly reduce the working time of medical professionals without decreasing the quality of learning content. The presented workflow can be used as a flexible approach for flipped classroom frameworks or other blended learning strategies where interactive videos are applicable.

Transmastoid implantability of an active transcutaneous bone conduction implant in adults with regard to the underlying pathology: a radiological simulation study.

OBJECTIVES: To compare the feasibility of transmastoid implantation of an active transcutaneous bone conduction device (BCD) in the most important pathologies of the temporal bone and the impact of implant lifts in adulthood. METHODS: First, clinical predominant pathologies for implantation of this BCD were evaluated by a literature review. Then, high-resolution CT of 240 temporal bones with neuro-otologic diseases (NOD), chronic otitis media (COM), or cholesteatoma, respectively, were investigated regarding their implantability, using a radiological simulation program. RESULTS: Chronic inflammatory diseases (CID) of the temporal bone with or without cholesteatoma account for most adults scheduled for an active BCD. Complete implantation was possible in almost all cases with NOD as well as COM, requiring an implant lift in 50% of COM and 20% of NOD (p = .025) cases. In contrast, in subjects with cholesteatoma, implantation required an additional tool in 92% of cases, leading to 59% implantability rate in these temporal bones. CONCLUSION: Adult subjects with CID of the temporal bone show more limiting anatomical conditions for transmastoid placement of an active transcutaneous BCD than those with single-sided deafness. Implant lifts increase the implantability significantly in subjects with COM and particularly in those with cholesteatoma.
