Tolosa Hunt Syndrome: MRI Findings.

Tolosa-Hunt syndrome (THS) is an idiopathic inflammatory condition involving the cavernous sinus and orbital apex with an incidence of 1 case per million per year. We report on a case of a 70-year-old male with atypical MRI findings, vision loss, and painless ophthalmoplegia.  Ophthalmic evaluation revealed his best-corrected visual acuity was 20/40 in the right eye and counting fingers at a 0.5-foot distance in the left eye. External examination of the left eye revealed limited ocular movement, proptosis, and a positive relative afferent pupillary defect. Complete blood count, inflammatory markers, and full biochemistry tests, including thyroid and liver function tests, were within the normal range. A magnetic resonance imaging of the orbits with and without contrast demonstrated a homogenously enhancing lesion at the posterior intraconal compartment of the left orbit, extending to the orbital apex with the involvement of the adjacent extraocular muscles. The patient was started on intravenous methylprednisolone 60 mg daily and later discharged on prednisone 5 mg daily with partial symptom improvement on follow-up. Resection and biopsy revealed a soft tissue lesion with mixed inflammatory infiltrate. The clinical, pathological, and imaging findings favored the diagnosis of THS.

Advancing Health Equity in Lung Cancer Screening and the Role of Humanomics.

Identifying and managing lung cancer, the leading cause of cancer-specific mortality, depend on multiple medical and sociodemographic factors. Humanomics is a model that acknowledges that negative societal stressors from systemic inequity affect individual health by altering pro-inflammatory gene expression. The same factors which may predispose individuals to lung cancer may also obstruct equitably prompt diagnosis and treatment. Increasing lung cancer screening access can lessen disparities in outcomes among disproportionately affected communities. Here, the authors describe several individual, provider, and health system-level obstacles to lung cancer screening and offer actionable solutions to increase access.

An Uncommon Case of Myocarditis Secondary to Durvalumab Plus Tremelimumab.

Tumor immunotherapy is an important clinical strategy for the treatment of various solid and hematological malignancies, and its use is on the rise. Immune checkpoint inhibitors (ICIs) are immunotherapies that boost anticancer immune responses by targeting receptors on the surface of T-lymphocytes. Two important ICIs are anti-programmed death ligand-1 (anti-PD-L1) monoclonal antibodies and anti-cytotoxic T-lymphocyte-associated antigen-4 (anti-CTLA-4) monoclonal antibodies. Tremelimumab (anti-CTLA-4) and durvalumab (anti-PD-L1) have been shown to be effective monotherapies. However, their combination has demonstrated effective and encouraging antitumor activity with manageable safety in patients with unresectable hepatocellular carcinoma. We present the case of an 80-year-old male with hepatocellular carcinoma who had undergone drug-eluting bead transarterial chemoembolization (DEB-TACE) on three occasions and had been started on a combination of ICIs, durvalumab, and tremelimumab. He subsequently developed various immune-related adverse effects in different organ systems, including hepatic and cardiovascular complications. Appropriate treatment was administered, but ultimately, he passed away. We aim to discuss the initial evaluation for suspected immune-related adverse events, specifically those related to myocarditis and its various manifestations, prognosis, and treatment.

Psychological Status of the Participants in Alzheimer's Prevention Initiative Autosomal Dominant Alzheimer's Disease Colombia.

BACKGROUND: The SARS-CoV2 global pandemic impacted participants in the Alzheimer's Prevention Initiative (API) Autosomal Dominant Alzheimer's Disease (ADAD) clinical trial, who faced three stressors: 1) fear of developing dementia; 2) concerns about missing treatment; and 3) risk of SARS-CoV2 infection. OBJECTIVE: To describe the frequency of psychological disorders among the participants of the API ADAD Colombia clinical study, treated by a holistic mental health team during the COVID-19 pandemic. The extent of use of mental health team services was explored considering different risk factors, and users and non-users of these services were compared. METHODS: Participants had free and optional access to psychology and psychiatry services, outside of the study protocol. Descriptive statistics was used to analyze the frequency of the mental health difficulties. A multivariable logistic regression model has been used to assess associations with using this program. RESULTS: 66 participants were treated by the Mental Health Team from March 1, 2020, to December 31, 2020. Before and after the start of the pandemic, the most common psychological problems were anxiety (36.4% before, 63.6% after) and depression (34.8% before, 37.9% after). 70% of users assisted by psychology and 81.6% of those assisted by psychiatry felt that the services were useful for them. Female sex, depression, and anxiety before the pandemic were positively associated with being assisted by either psychology or psychiatry, while the association with hyperlipidemia was negative. CONCLUSIONS: A holistic mental health program, carried out in the context of a study, could mitigate psychopathology during pandemics such as COVID-19.

Relationship between the Dental Aesthetic Index and Discrepancy Index.

OBJECTIVE: To establish the association between malocclusion severity and orthodontic case complexity as assessed by the Dental Aesthetic Index (DAI) and the American Board of Orthodontics Discrepancy Index (ABO-DI), respectively. DESIGN: Cross-sectional study. SETTING: Pre-treatment dental casts and radiographs from 500 individuals (294 women and 206 men; mean age = 26.06 ± 11.58 years) were randomly selected from the orthodontics department of a private university. METHODS: Malocclusion severity was assessed using DAI and case complexity was evaluated with ABO-DI. Three previously calibrated operators performed the measurements. Spearman's correlation analysis, Mann-Whitney U test, Kruskal-Wallis test and a linear generalised model were used for statistical evaluation (P < 0.05 was considered significant). RESULTS: Although the correlation (r = 0.45; P < 0.0001) between malocclusion severity and case complexity was moderate, strong evidence of an association (P < 0.001) between dichotomised DAI and ABO-DI total scores was observed. The linear generalised model showed that for each point of increase in DAI score, the ABO-DI score increased an average of 0.3624 points (P < 0.0001). CONCLUSION: An association between malocclusion severity and case complexity is suggested. A linear generalised model could be used to predict the complexity of the case from the malocclusion severity (DAI score).
