A 67-year-old man with relapsed anaplastic large cell lymphoma received salvage chemotherapy, and pegfilgrastim was used to prevent febrile neutropenia. On day 18 of chemotherapy, he developed a pseudogout attack. Although the first symptoms improved, another pseudogout attack occurred when he received the second course of chemotherapy and pegfilgrastim. Filgrastim was then used for the third course of chemotherapy, and a pseudogout attack did not occur. The serum granulocyte-stimulating factor (G-CSF) level was extremely elevated only when pegfilgrastim was used, suggesting a relationship between pseudogout and G-CSF. Pseudogout should be recognized as an adverse effect of pegfilgrastim.

Article Synopsis
- The study aims to assess tryptophanyl tRNA synthetase (WRS) as a diagnostic tool for septic arthritis of the knee, comparing its effectiveness to other biomarkers in distinguishing it from other forms of arthritis.* -
- A total of 62 patients with various arthritis types were analyzed, revealing that those with septic arthritis had significantly higher levels of WRS and other inflammatory markers, with WRS showing a high specificity (87.5%) and sensitivity (83.3%).* -
- The findings suggest WRS in synovial fluid could serve as a reliable biomarker for diagnosing septic arthritis, marking the need for further testing in separate patient groups.*
Acute monoarticular hip joint pseudogout masquerading as septic arthritis.

Trauma and Orthopaedic Surgery, North Middlesex University Hospital, London, UK.
Monoarticular pseudogout of the hip joint is rare and to the best of our knowledge only four other cases exist in the literature. We present a case of primary monoarticular pseudogout affecting the right hip in a patient in his 50s. The diagnosis was confirmed through ultrasound-guided synovial fluid aspiration and crystal analysis.

Inborn metabolic diseases (IMD) are rare conditions that can be diagnosed during adulthood. Patients with IMD may have joint symptoms and the challenge is to establish an early diagnosis in order to institute appropriate treatment and prevent irreversible damage. This review describes the joint manifestations of IMD that may be encountered in adults.

Calcium pyrophosphate deposition involves deposition of calcium pyrophosphate dihydrate crystals in various joints throughout the body. The term "pseudogout" refers to an acute attack of calcium pyrophosphate crystal-induced arthritis. Though clinical presentation and joint involvement vary, involvement of the lumbar spine is rare.
