Introduction: Choroidal metastasis from renal cell carcinoma is relatively rare and unresponsive to systemic treatment.

Case Presentation: A man in his eighties with left renal cell carcinoma and pulmonary metastasis developed visual impairment in the left eye during primary treatment with ipilimumab and nivolumab followed by secondary treatment with cabozantinib. Consultation with an ophthalmologist revealed choroidal metastasis, which was subsequently treated with local radiotherapy (3 Gy × 10 Fr), resulting in a significant reduction in the metastatic lesions.

Article Synopsis
  • The tibial tuberosity consists of two parts: a superficial area with a patellar tendon and a deeper area of uncalcified cartilage; reduced calcification can lead to Osgood-Schlatter disease.
  • A study involving 20 male Wistar rats examined how decreased mechanical stimulation (via hind-limb suspension) affected the structure and calcification of the tibial tuberosity compared to a control group, revealing significant differences in tissue maturity.
  • Results indicated that reduced load on the tibial tuberosity led to pathological changes and calcification, underscoring the need for adequate mechanical stimulation through exercise to maintain healthy bone and joint structures.

Background: The maxilla comprises horizontal and vertical buttresses, each with specific functions, supporting various organs, such as the eyes, nose, and oral cavity. Notably, they combine to form a three-dimensional structure, which enables the buttresses to provide their inherent support strength. However, reconstructing the maxilla after maxillectomy by assembling new buttresses is challenging.

For over 12 years since the 2011 East Japan Earthquake, the decontamination of radioactive materials is still incomplete. Although evacuation orders had been lifted in ~15% of Futaba town, the site of the Fukushima Daiichi Nuclear Power Plant, by August 2022, anxiety regarding the effects of nuclear radiation persists among evacuees, and their intention to return (ITR) remains low. As of August 2023, only 90 residents lived there.

  • Excessive carbohydrate intake leading to hypophosphatemia is a key factor in refeeding syndrome, which can also cause liver injury and hypoglycemia in malnourished patients, but the exact relationship is still being studied.
  • A study involving 48 patients with anorexia nervosa found that significant liver volume reductions were linked to episodes of severe hypoglycemia, especially when patients had very low nutritional intake.
  • The findings suggest careful re-nutrition strategies, starting at 500 kcal/day and gradually increasing, may help minimize complications related to hypoglycemia and liver dysfunction in these patients.

Lumbar spinal stenosis (LSS) is a degenerative disease characterized by intermittent claudication and numbness in the lower extremities. These symptoms are caused by the compression of nerve tissue in the lumbar spinal canal. Ligamentum flavum (LF) hypertrophy and spinal epidural lipomatosis in the spinal canal are known to contribute to stenosis of the spinal canal: however, detailed mechanisms underlying LSS are still not fully understood.

In the typical Orbison illusion, the sides of a square placed on concentric circles appear to be bending toward the center of the circles. We report a motion version of the Orbison illusion (namely, the kinetic Orbison illusion). When a dot moves along a square trajectory against a background of concentric circles, the sides of the trajectory appear to bend toward the center and the corners appear to be sharpened.
