Background: Dysmorphology evaluation is important for congenital heart disease (CHD) assessment, but there are no prior investigations quantifying the screening performance compared to standardized genetics evaluations. We investigated this through systematic dysmorphology assessment in CHD patients with standardized genetic testing in primarily pediatric patients with CHD.

Methods: Dysmorphology evaluations preceding genetic testing results allowed us to test for associations between dysmorphic status and genetic diagnoses while adjusting for extracardiac anomalies (ECAs).

Article Synopsis
  • Researchers are exploring how people perceive odors, often using complex smell tests in clinical settings, but these tests can be time-consuming and require specialized staff.
  • The existing automated odor delivery systems are often expensive and cumbersome, limiting their practical use in various environments.
  • A new portable, affordable odor delivery device has been developed, capable of offering 24 different odors and allowing users to self-administer smell tests, potentially changing the way olfactory perception is assessed in everyday life.

Background: In the absence of direct evidence supporting how to use nasal endoscopy findings to judge chronic rhinosinusitis (CRS) disease control, experts' practice patterns could provide guidance.

Methodology: Participants consisted of a diverse group of twenty-nine rhinologists. Participants were presented with every possible combination of bilateral nasal endoscopy findings represented by the modified Lund-Kennedy (MLK; range: 0-12) endoscopic scoring system and Nasal Polyp Score (NPS; range: 0-8).

Cognitive symptoms persisting beyond the acute phase of COVID-19 infection are commonly described for up to 2 years after infection. The relationship between cognitive performance, in particular episodic memory processes observed chronically after infection, and cytokine levels in the acute phase of COVID-19 has not yet been identified in humans. To determine whether the levels of cytokines IL1β, IL-6 and TNFα secreted in the acute phase of SARS-CoV-2 infection are associated and predict verbal and visuospatial episodic memory performance in humans 6 to 9 months and 12 to 15 months post-infection.

Purpose: To determine whether odontogenic maxillary sinusitis, either alone (OMSw/oFB) or in combination with fungus ball (OMSwFB), is associated with specific clinical characteristics and treatment outcomes compared to non-odontogenic maxillary sinusitis.

Materials And Methods: A retrospective cohort study was performed on patients who underwent surgical treatment for chronic maxillary sinusitis between 2013 and 2021. OMSw/oFB and OMSwFB patients, were selected as the study group, while patients diagnosed with non-odontogenic maxillary sinusitis (non-OMS) were enrolled as the control group.

Objective: to provide anatomic confirmation that standard methods which practitioners skilled in palpation use, can reliably identify the most likely site of emergence of the greater occipital nerve in most patients. The location and frequency of subcutaneous emergence of the greater occipital nerve and occipital artery with respect to the external occipital protuberance-mastoid line are reported.

Methods: The external occipital protuberance and the mastoid processes were identified by palpation bilaterally on 57 body donors and the medial trisection point of a line connecting these bony landmarks was identified.

Reduced ocular perfusion likely contributes to glaucomatous damage at the optic nerve head (ONH). In recent decades, investigators have focused heavily on ocular perfusion pressure and other factors affecting blood flow to the eye. Comparatively, far less attention has been focused on the blood vessels themselves.

Congenital heart disease (CHD) is the most common birth defect and a leading cause of infant mortality. CHD often has a genetic etiology and recent studies demonstrate utility in genetic testing. In clinical practice, decisions around genetic testing choices continue to evolve, and the incorporation of rapid genome sequencing (rGS) in CHD has not been well studied.

Background: Despite numerous observations of neuropsychological deficits immediately following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, little is known about what happens to these deficits over time and whether they are affected by changes in fatigue and any psychiatric symptoms. We aimed to assess the prevalence of neuropsychological deficits at 6-9 months and again at 12-15 months after coronavirus disease 2019 (COVID-19) and to explore whether it was associated with changes in fatigue and psychiatric symptoms.

Methods: We administered a series of neuropsychological tests and psychiatric questionnaires to 95 patients (mean age = 57.

Article Synopsis
  • The study assessed current clinical practices for olfactory dysfunction (OD) among ENT surgeons, focusing on the differences between the UK and international approaches.
  • Most UK clinicians do not perform psychophysical smell testing, with rhinologists conducting it more frequently than non-rhinologists, while international respondents reported higher testing rates.
  • The survey highlighted barriers like time and funding, revealed a desire for more training in smell testing among 75% of participants, and noted that patient-reported outcomes are rarely used in both the UK and internationally.

Following the European Forum for Research and Education in Allergy and Airway Diseases (EUFOREA) treatment algorithm for chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP), patients suffering from severe uncontrolled CRSwNP are recommended to receive oral corticosteroids, (revision) sinus surgery, systemic biologicals and/or aspirin treatment after desensitization (ATAD). Given the major differences in indications, outcomes, practical considerations, risks and costs of these key pillars of treatment, there is a growing need to define criteria for each treatment option and list the clinically relevant and major considerations for them. This EUFOREA document therefore provides an expert panel overview of the expected outcomes, specific considerations and (contra)indications of the five major treatment arms of severe uncontrolled CRSwNP: oral corticosteroids, primary and revision sinus surgery, biological treatment and ATAD.

Background: Although most patients with post-traumatic olfactory dysfunction (PTOD) undergo MRI, there is no consensus about its diagnostic or prognostic value. The aims were: 1) to classify the extent of post-traumatic neurodegeneration; 2) to determine its relationship with chemosensory dysfunction (smell, taste, trigeminal); and 3) to establish whether MRI can predict olfactory improvement.

Methodology: We conducted a retrospective cohort study based on a series of 56 patients with PTOD.

Background: In chronic rhinosinusitis (CRS), nasal obstruction can often be explained by anatomical deformities, polyps, or congested nasal mucosa. However, in cases with little deformity or inflammation, perceived nasal obstruction may result from reduced airflow perception caused by an alteration of the intranasal trigeminal system. The aim of this study was to assess this association.

Background Chromosomal microarray analysis (CMA) provides an opportunity to understand genetic causes of congenital heart disease (CHD). The methods for describing cardiac phenotypes in patients with CMA abnormalities have been inconsistent, which may complicate clinical interpretation of abnormal testing results and hinder a more complete understanding of genotype-phenotype relationships. Methods and Results Patients with CHD and abnormal clinical CMA were accrued from 9 pediatric cardiac centers.
