Approach to otitis externa.

Objective: To provide family physicians with a practical evidence-based approach to management of otitis externa.

Sources Of Information: The approach described is based on MEDLINE and PubMed literature published between 1993 and 2023.

Main Message: Otitis externa is diffuse inflammation of the external auditory canal and typically occurs from moisture exposure and trauma.

COVID-19 Outcomes Among Hematopoietic Cell Transplant and Chimeric Antigen Receptor T-Cell Recipients in the Era of SARS-CoV-2 Omicron Variants and COVID-19 Therapeutics.

Recipients of cellular therapies, including hematopoietic cell transplant (HCT) and chimeric antigen receptor T-cell (CART) therapy, are at risk for poor outcomes from coronavirus disease 2019 (COVID-19). There are limited data describing outcomes among patients in the pre- and early post-cellular therapy period during the Omicron era when multiple antiviral therapeutics were widely available. The objective of this study is to describe COVID-19 treatment and outcomes in patients diagnosed with COVID-19 during the pre- or early post-cellular therapy period.

Clinical outcomes and frequency of persistent infection among immunosuppressed patients treated with bebtelovimab for COVID-19 infection at an ambulatory cancer center.

Background: There are limited data on clinical outcomes associated with the use of bebtelovimab for the treatment of coronavirus disease 2019 (COVID-19) among cancer patients. We aimed to define the clinical characteristics and outcomes among patients receiving bebtelovimab as part of the COVID-19 therapeutics program at our cancer center.

Methods: This is a retrospective cohort study of immunosuppressed adult patients who received bebtelovimab at Fred Hutchinson Cancer Center between March 2022, and November 2022.

Hearing aid utilization in Ontario - a population based study.

Background: Hearing loss is one of the most common sensory impairments and hearing aids are the most common unmet assistive device need among individuals with a disability. The benefits of hearing interventions are well-documented as they are known to deter the sequalae of hearing loss including social isolation, poor mental health, falls and cognitive decline. Identifying trends in hearing aid users can provide valuable information for improving access to hearing loss interventions.

Approach to hearing loss.

Objective: To provide family physicians with a practical evidence-based approach to the management of patients with hearing loss.

Sources Of Information: MEDLINE and PubMed databases were searched for English-language hearing loss research, review articles, and guidelines published between 1980 and 2020. Most of the retrieved articles provided level II or III evidence.

Association of tympanostomy tubes with future assistive hearing devices-a population based study.

Background: Ear (tympanostomy) tube (TT) placement is a common ambulatory surgery in children. Despite the commonality of this treatment, the long-term effects are unknown. The objective of this study was to determine the rate of permanent hearing loss, as measured by use of a rehabilitative hearing device.

Cancer overturned: Endometrioma mimicking granulosa cell tumor and the importance of FOXL2 analysis.

Background: Various ovarian neoplasms may show histological findings that are morphologically indistinguishable from adult granulosa cell tumor (AGCT).

Case Presentation: A 36 year-old women presented with left lower extremity pain and numbness. Ultrasound revealed a 10 cm left adnexal mass treated with ovarian cystectomy.

Management of disseminated intravascular coagulation in a patient with hepatic angiosarcoma: A case report.

Rationale: Hepatic angiosarcoma is a rare endothelial cell tumor that may lead to concurrent consumptive coagulopathies including disseminated intravascular coagulation (DIC). This report details a multifaceted approach to managing DIC in a patient with advanced-stage hepatic angiosarcoma, which continued to progress after a brief response to taxane-based chemotherapy.

Patient Concerns: A 55-year-old man with a recent history of hemorrhoids and hemarthroses presented with acute rectal bleeding.

Audiometric Testing Guideline Adherence in Children Undergoing Tympanostomy Tubes: A Population-Based Study.

Objective Tympanostomy tube (TT) insertion is the most common ambulatory surgery performed on children. American Academy of Otolaryngology-Head and Neck Surgery Founda-tion (AAO-HNSF) Clinical Practice Guidelines (CPGs) recommend hearing testing for all pediatric TT candidates. The aim of this study was to assess audiometric testing in this population.

Mutant Calreticulin Requires Both Its Mutant C-terminus and the Thrombopoietin Receptor for Oncogenic Transformation.

Unlabelled: Somatic mutations in calreticulin (CALR) are present in approximately 40% of patients with myeloproliferative neoplasms (MPN), but the mechanism by which mutant CALR is oncogenic remains unclear. Here, we demonstrate that expression of mutant CALR alone is sufficient to engender MPN in mice and recapitulates the disease phenotype of patients with CALR-mutant MPN. We further show that the thrombopoietin receptor MPL is required for mutant CALR-driven transformation through JAK-STAT pathway activation, thus rendering mutant CALR-transformed hematopoietic cells sensitive to JAK2 inhibition.

Distinct effects of concomitant Jak2V617F expression and Tet2 loss in mice promote disease progression in myeloproliferative neoplasms.

Signaling mutations (eg, JAK2V617F) and mutations in genes involved in epigenetic regulation (eg, TET2) are the most common cooccurring classes of mutations in myeloproliferative neoplasms (MPNs). Clinical correlative studies have demonstrated that TET2 mutations are enriched in more advanced phases of MPNs such as myelofibrosis and leukemic transformation, suggesting that they may cooperate with JAK2V617F to promote disease progression. To dissect the effects of concomitant Jak2V617F expression and Tet2 loss within distinct hematopoietic compartments in vivo, we generated Jak2V617F/Tet2 compound mutant genetic mice.
