Nephrogenic diabetes insipidus (NDI) is characterized by polyuria and polydipsia, high serum osmolality, and low urine osmolality because of resistance to antidiuretic hormone. Lithium is commonly used to treat psychiatric disorders, and NDI is one of the common renal side effects of lithium therapy. On the other hand, NDI induced by lithium medication in a patient after a coronavirus disease-19 (COVID-19) infection has not been reported. This paper presents a patient who developed new-onset NDI secondary to a COVID-19 infection despite being on a stable lithium dose for several years. This case highlights the importance of considering a COVID-19 infection as a possible cause of NDI in patients taking lithium medication.

The detrimental effects of hyperlipidemia on the healing of rotator cuff tears are well documented. The proposed underlying mechanisms for these effects include alterations in the extracellular matrix, inflammation, and oxidative stress, which hamper the reparative processes in the affected tendon tissues. Recent therapeutic strategies target these pathways, reflecting a growing body of research dedicated to mitigating these effects and promoting healing. This literature review aims to provide a comprehensive understanding of the pathophysiology underlying rotator cuff tears, examine the interplay between hyperlipidemia and rotator cuff tear healing, synthesize current knowledge on contributing biological mechanisms, and outline potential therapeutic interventions to optimize clinical management and treatment outcomes for patients.

An 83-year-old man with cholangiocarcinoma developed immune checkpoint inhibitor-associated myositis after two cycles of durvalumab, presenting with muscle weakness and myalgia. His serum creatine kinase (CK) level peaked at 26,329 U/L. Needle electromyography confirmed a myogenic process, and MRI revealed extensive muscle edema. Muscle biopsy indicated multifocal necrotic fibers. Following steroid treatment, his CK levels normalized and muscle strength returned. This case represents the first reported instance of durvalumab-associated myositis in Korea.

Hyperbaric oxygen therapy (HBOT) was conducted on two male patients with chronic prostatitis/chronic pelvic pain syndrome who were resistant to conventional medical therapies. Both patients underwent 20 sessions of 100% oxygen inhalation (2.0 atmosphere absolute for 90 min/day, five days/week for four weeks) in a hyperbaric chamber. The follow-up period was three months. Although the patients reported a slight improvement in the pain domain of the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) after HBOT, no changes were noted in the other domains of NIH-CPSI and International Prostate Symptom Score. No adverse events were encountered during or after HBOT.
