Silent Inflammation: A Case of Blurry Vision Raising Diagnostic Challenges in an Elderly Patient.

Giant cell arteritis (GCA) is a large vessel vasculitis with cranial and extracranial vessel involvement. Clinicians suspect GCA when a patient exhibits symptoms or exam findings of temporal headache with sudden vision loss, jaw or tongue claudication, scalp tenderness, abnormal temporal artery exam, and diagnostic findings, including elevated inflammatory markers. We present a case, which highlights that, despite established diagnostic measures, challenges persist.

Environmental changes, such as climate warming and higher herbivory pressure, are altering the carbon balance of Arctic ecosystems; yet, how these drivers modify the carbon balance among different habitats remains uncertain. This hampers our ability to predict changes in the carbon sink strength of tundra ecosystems. We investigated how spring goose grubbing and summer warming-two key environmental-change drivers in the Arctic-alter CO fluxes in three tundra habitats varying in soil moisture and plant-community composition.

Article Synopsis
- Drought events are becoming more common in grasslands and shrublands, affecting soil organic carbon (SOC), which includes different forms like particulate (POC) and mineral-associated organic carbon (MAOC).
- A global study over 19 sites revealed that in wetter areas (aridity index > 0.65), extreme drought led to a significant decrease in SOC (7.9%) and POC (15.9%), but MAOC levels remained unchanged.
- In drier regions (aridity index < 0.65), drought did not significantly affect any type of soil organic carbon, indicating that the impact of drought on SOC is influenced by environmental aridity and rainfall variability.
Elevations in depression and anxiety symptoms prior to discharge from partial hospitalization.
Cogn Behav Ther
September 2024
Behavioral Health Partial Hospital Program, McLean Hospital, Belmont, MA, USA.
Discharge from psychiatric treatment has been established as an emotionally intense and vulnerable time for patients; however, to date no studies have investigated symptoms directly preceding discharge and the impact on post-discharge outcomes. Our primary aim was to assess the prevalence of elevations in depression and anxiety symptoms prior to discharge from a partial hospitalization program (PHP). Our secondary aim was to assess whether these pre-discharge elevations predict post-discharge outcomes.

Department of Ophthalmology, Orbit, Oculoplasty and Reconstructive Surgery, Regional Institute of Ophthalmology, Medical College and Hospital Kolkata, Kolkata, West Bengal, India.
Purpose: To describe the surgical technique using a 10/14 French silicone urinary catheter as a novel tissue expander for repair of defects after removal of eyelid tumors. This device recruits additional tissue by tissue expansion for repair of large eyelid defects.
Methods: A prospective noncomparative, interventional case study was conducted over a period of 3 years in which 30 patients were enrolled.
