Purpose: To describe the retinal phenotype of an unusual case of anti-TRPM1 autoantibody-positive unilateral melanoma-associated retinopathy (MAR) triggered by nivolumab therapy and compare with the phenotype of -associated Congenital Stationary Night Blindness (-CSNB).

Observations: Unilateral MAR was diagnosed 3 months after starting nivolumab therapy for consolidation of a successfully treated melanoma. Retinal autoantibodies against TRPM1 were identified.

Purpose: To describe a patient with a unique retinal phenotype of probable Susac syndrome.

Observations: A 47-year-old female who presented with bilateral tinnitus and vision changes was found to have bilateral sensorineural hearing loss and many bilateral retinal arteriolar Gass plaques. She had bilateral scotomas corresponding with temporal thinning and atrophy of the inner nuclear layer (INL) on OCT.

Purpose: Exudative retinal detachment (ERD) may result from laser photocoagulation for retinopathy of prematurity. Although risk factors have been hypothesized from case reports, comparative studies have not been reported. We sought to evaluate risk factors for ERD following laser, comparing affected and unaffected infants.

Purpose: To describe a case of unilateral congenital retinal macrovessel with a retinal cavernous hemangioma in a patient with Cowden syndrome (CS). In addition, we summarize previously reported cases of ocular findings in CS in the literature.

Methods: Observational case report and literature review.

Introduction: Currently, little is known regarding bone health surveillance for glucocorticoid-exposed non-infectious uveitis (NIU) patients or their baseline risks of skeletal fragility outcomes.

Methods: Using claims data, we calculated rates of dual-energy x-ray absorptiometry (DXA) screening for glucocorticoid-exposed NIU and rheumatoid arthritis (RA) patients. Separately, we compared risks of skeletal fragility metrics amongst NIU patients, RA patients, and controls, independent of glucocorticoid use.

Background: Using telemedicine for diabetic retinal screening is becoming popular especially amongst at-risk urban communities with poor access to care. The goal of the diabetic telemedicine project at Temple University Hospital is to improve cost-effective access to appropriate retinal care to those in need of close monitoring and/or treatment.

Methods: This will be a retrospective review of 15 months of data from March 2016 to May 2017.

Electrostimulation of plants can induce plant movements, activation of ion channels, ion transport, gene expression, enzymatic systems activation, electrical signaling, plant-cell damage, enhanced wound healing, and influence plant growth. Here we found that electrical networks in plant tissues have electrical differentiators. The amplitude of electrical responses decreases along a leaf and increases by decreasing the distance between polarizing Pt-electrodes.

Article Synopsis
  • Transfusions are crucial for treating sickle cell disease but can lead to alloimmunization, a severe complication that is not fully understood.
  • Research indicates that the body's anti-inflammatory response to heme, a substance released during chronic hemolysis in sickle cell patients, is impaired in those who are alloimmunized, increasing their risk for the condition.
  • Findings suggest that heme can help regulate immune responses in non-alloimmunized patients by influencing dendritic cell activity, hinting at potential new therapies to prevent alloimmunization in sickle cell patients.

Background: Red blood cell (RBC) alloimmunization is a concern for patients who receive multiple or chronic transfusions. Alloimmunization prevalence in transfused patients with bone marrow failure syndrome (BMFS) is unknown. This study aimed to determine physician practice for RBC antigen matching, immunization rates, and antibody specificities in patients with BMFS.

Histone deacetylase inhibitors (HDIs) are under investigation for the treatment of a number of human health problems. HDIs have proven therapeutic value in refractory cases of cutaneous T-cell lymphoma. Electrocardiographic ST segment morphological changes associated with HDIs were observed during development.
