Pseudogout is characterized by the deposition of calcium pyrophosphate dihydrate crystals (CPPD), primarily affecting large joints. Extra-articular manifestations, particularly in the head and neck region, are exceedingly rare. We report a unique case of bilateral isolated pseudogout of the middle ear manifesting with progressive conductive hearing loss as the first and only symptom of pseudogout. Otoscopy and CT scan often yield a differential diagnosis that includes tumors or cholesteatoma, necessitating surgery with histopathological examination. The definitive diagnosis is confirmed upon identification of calcium pyrophosphate dihydrate crystals. In most cases, removal of the crystals results in resolution of conductive hearing loss.

This case report describes rare concomitant allergic fungal rhinosinusitis (AFRS) and chronic granulomatous invasive fungal sinusitis (CGIFS) in a 34-year-old woman with acute lymphoblastic leukemia and graft-versus-host disease (GVHD) post bone marrow transplantation. Initially presenting with rhinorrhea and nasal obstruction, the patient was diagnosed with AFRS in the right maxillary sinus, followed by a postoperative course of CGIFS in the left nasal cavity, showcasing the unique occurrence. She was not immunocompromised during diagnosis. CGIFS may have occurred because of surgery; however, voriconazole led to significant improvement. This case highlights noninvasive and invasive fungal infections in patients with chronic rhinosinusitis and a history of GVHD and underscores the complexity of diagnosing and managing such cases.

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a potentially life-threatening syndrome for which early recognition and treatment are essential for improving outcomes. HLH is characterized by uncontrolled immune activation leading to fever, cytopenias, hepatosplenomegaly, coagulation abnormalities, and elevated typical markers. This condition can be genetic or secondary, with the latter often triggered by infections. Here, we present a unique case of HLH secondary to acute otitis media (AOM), a common ear infection.
METHODS: We describe a 4-year-old boy who initially presented with a high fever and otalgia, later diagnosed with bilateral AOM. Despite antibiotic treatment, his condition deteriorated.
METHODS: The patient fulfilled diagnostic criteria for HLH.
METHODS: Aggressive treatment by using combination therapy with immunoglobulins, intravenous steroids (dexamethasone), cyclosporine, and etoposide was performed.
RESULTS: After 1 month of treatment, improvement in the otologic symptoms was observed, and hematological findings gradually improved and normalized.
CONCLUSIONS: The link between AOM and HLH may be associated with inflammatory responses and immunological mechanisms, highlighting the importance of considering HLH in severe infection cases. This case emphasizes the need for prompt diagnosis and management, especially in secondary HLH scenarios, to improve patient outcomes. It is imperative to be aware of the potential correlation between these 2 conditions, and healthcare professionals should consider the likelihood of HLH.

Acute suppurative otitis media can occasionally result in facial paralysis, which calls for prompt diagnosis and treatment. Facial paralysis, a synonym for Bell\'s palsy, is a condition that causes rapid weakening of one side of the face muscles, leading to drooping of the face on that side. A major factor in determining the course of the condition is rehabilitation through physiotherapy. Here, we present a case of a 26-year-old female who felt discomfort in her left ear on February 21, 2024, but chose to ignore it then. She observed an abrupt deviation in her mouth and visited a rural hospital, where she was admitted. Facial asymmetry was observed during the examination, and she was found to have a grade V on the House-Brackmann scale. A near-normal muscle action was initiated by mime therapy, and proprioceptive stimulation was given by facial proprioceptive neuromuscular facilitation along with electrical stimulation. All these approaches benefited the patient in a significant manner.

Hearing impairment is the most prevalent sensory disease in humans and can have dramatic effects on the development, and preservation, of our cognitive abilities and social interactions. Currently 20 % of the world\'s population suffer from a form of hearing impairment; this is predicted to rise to 25 % by 2050. Despite this staggering disease load, and the vast damage it inflicts on the social, medical and economic fabric of humankind, our ability to predict, or prevent, the loss of hearing is very poor indeed. We here make the case for a paradigm shift in our approach to studying deafness. By exploiting more forcefully the molecular-genetic conservation between human hearing and hearing in morphologically distinct models, such as the fruit fly Drosophila melanogaster, we believe, a deeper understanding of hearing and deafness can be achieved. An understanding that moves beyond the surface of the \'deafness genes\' to probe the underlying bedrock of hearing, which is shared across taxa, and partly shared across modalities. When it comes to understanding the workings (and failings) of human sensory function, a simple fruit fly has a lot to offer and a fly eye might sometimes be a powerful model for a human ear. Particularly the use of fly avatars, in which specific molecular (genetic or proteomic) states of humans (e.g. specific patients) are experimentally reproduced, in order to study the corresponding molecular mechanisms (e.g. specific diseases) in a controlled yet naturalistic environment, is a tool that promises multiple unprecedented insights. The use of the fly - and fly avatars - would benefit humans and will help enhance the power of other scientific models, such as the mouse.

Objective: To examine the surgical, audiological and patient-reported outcomes of the Osia 2 implant. Methods: Data from 14 consecutive subjects undergoing implantation between April 2022 and November 2023 were reviewed. Ten subjects had conductive hearing loss, three had mixed hearing loss and one had single-sided deafness (SSD). Warble tone thresholds, Pure Tone Average (PTA4) and Speech Discrimination Score (SDS) in quiet and in noise were determined unaided and aided. The subjective outcome was determined from two standardized questionnaires: (1) International Outcome Inventory for Hearing Aids (IOI-HA) and (2) Speech, Spatial and Qualities of Hearing Scale 12 (SSQ12b). Results: Unexpected postoperative pain was found in four cases. The warble tone thresholds exhibited a consistent reduction across all frequencies, contributing to a mean decrease of 27 dB in the aided PTA4. SDS demonstrated notable improvements, with a 57.3% increase at 50 dB and a 55.6% increase at 65 dB. In noise, SDS exhibited a 43.9% improvement. The mean IOI-HA Score was 3.8, and the mean overall score for SSQ12b was 6.6, with consistent findings across the subgroups. Conclusions: The Osia device emerges as a promising recommendation for individuals with conductive or mixed hearing loss, possibly also for those with SSD. Its safety and efficacy profile aligns with the broader category of active transcutaneous devices, demonstrating a reduced risk of wound infection compared to percutaneous alternatives. Both audiological assessments and subjective evaluations revealed positive outcomes.

BACKGROUND: Non-invasive ventilation (NIV) is a standard of care for hypercapnic chronic respiratory failure (CRF). Obstructive sleep apnea syndrome (OSA) frequently contributes to hypoventilation in CRF patients. CPAP improves hypercapnia in selected COPD and obese patients, like NIV. We aimed to describe the profile of patients switching from NIV to CPAP in a cohort of patients on long-term ventilation and to identify the factors associated with a successful switch.
METHODS: In this case-control study, 88 consecutive patients who were candidates for a NIV-CPAP switch were compared with 266 controls among 394 ventilated patients treated at the Dijon University Hospital between 2015 and 2020. They followed a standardized protocol including a poly(somno)graphy recorded after NIV withdrawal for three nights. CPAP trial was performed if severe OSA was confirmed. Patients were checked for recurrent hypoventilation after 1 and 23[14-46] nights under CPAP.
RESULTS: Patients were 53% males, median age 65 [56-74] years, and median BMI 34 [25-38.5] kg/m2. Sixty four percent of patients were safely switched and remained on long-term CPAP. In multivariate analysis, the probability of a NIV-CPAP switch was correlated to older age (OR: 1.3 [1.01-1.06]), BMI (OR: 1.7 [1.03-1.12]), CRF etiology (OR for COPD: 20.37 [4.2-98,72], OR for obesity: 7.31 [1.58-33.74]), circumstances of NIV initiation (OR for acute exacerbation: 11.64 [2.03-66.62]), lower pressure support (OR: 0.90 [0.73-0.92]), lower baseline PaCO2 (OR: 0.85 [0.80-0.91]) and lower compliance (OR: 0.76 [0.64-0.90]). Among 72 patients who went home under CPAP, pressure support level was the only factor associated with the outcome of the NIV-CPAP switch, even after adjustment for BMI and age (p=0.01) with a non-linear correlation. Etiology of chronic respiratory failure, age, BMI, baseline PaCO2, circumstances of NIV initiation, time under home NIV or NIV compliance were not predictive of the outcome of the NIV-CPAP switch.
CONCLUSIONS: A NIV-CPAP switch is possible in real life conditions in stable obese and COPD patients with underlying OSA.

The primary malignant melanoma of the parotid is a rare and complex clinical entity, posing numerous diagnostic challenges due to the absence of melanin in the tumor and its histological similarities with other poorly differentiated lesions. Accurate diagnosis often requires advanced imaging techniques and immunohistochemical procedures to identify specific melanoma markers. Therapeutically, total parotidectomy with simultaneous cervical dissection is frequently recommended, although approaches combining surgery, chemotherapy, radiotherapy, or even immunotherapy are also being explored. Despite these advancements, malignant parotid melanoma continues to be associated with a grim prognosis, emphasizing the importance of ongoing research to improve therapeutic options and understanding of this rare pathology.

A vestibular schwannoma is a benign tumor; however, the schwannoma itself and interventions can cause sensorineural hearing loss. Most vestibular schwannomas are unilateral tumors that affect hearing only on one side. Attention has focused on improving the quality of life for patients with unilateral hearing loss and therapeutic interventions to address this issue have been emphasized. Herein, we encountered a patient who was a candidate for hearing preservation surgery based on preoperative findings and had nonserviceable hearing after the surgery, according to the Gardner-Robertson classification. Postoperatively, the patient had decreased listening comprehension and ability to localize sound sources. He was fitted with bilateral hearing aids, and his ability to localize sound sources improved. Although the patient had postoperative nonserviceable hearing on the affected side and age-related hearing loss on the unaffected side, hearing aids in both ears were useful for his daily life. Therefore, the patient was able to maintain a binaural hearing effect and the ability to localize the sound source improved. This report emphasizes the importance of hearing preservation with vestibular schwannomas, and the demand for hearing loss rehabilitation as a postoperative complication can increase, even if hearing loss is nonserviceable.

Recommendations for or against the use of interventions need to consider both desirable and undesirable effects as well as patients\' values and preferences (V&P). In the decision-making context, patients\' V&P represent the relative importance people place on the outcomes resulting from a decision. Therefore, the balance between desirable and undesirable effects from an intervention should depend not only on the difference between benefits and harms but also on the value that patients place on them. V&P are therefore one of the criteria to be considered when formulating guideline recommendations in the Evidence-to-Decision framework developed by the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) Working Group. Patients\' V&P may be quantified through utilities, which can be elicited using direct methods (e.g., standard gamble or time trade-off) or indirect methods (using validated instruments to measure health-related quality of life, such as EQ-5D). The GRADE approach recommends conducting systematic reviews to summarise all the available evidence and assess the degree of certainty on V&P. In this article, we discuss the importance of considering patients\' V&P and provide examples of how they are considered in the 2024 person-centred Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines.
