Xanthoma is a rare condition mostly caused by hyperlipidemia. The pathogenesis of gout is hyperuricemia, which is caused by a disorder of purine metabolism and/or a decrease in uric acid excretion. Xanthoma combined with gout is very rare. This case report presents magnetic resonance images of a case of xanthoma combined with gout infiltration of the Achilles tendon.

Uric Acid Excretion

Background:Underexcretion of uric acid is the dominant mechanism leading to hyperuricemia [1] and the 24-hour urinary uric acid excretion is an important measurement. However, it is inconvenient due to accurate timing and complete collection of the specimen.Objectives:The aim of this study was to investigate the relationship between serum uric acid to creatinine ratio (sUACR) and 24-hour urinary uric acid excretion in gout patients.Methods:A total of 110 gout patients fulfilling 2015 ACR/EULAR classification criteria from Guangdong Second Provincial General Hospital from January 2019 to January 2021 were retrospectively enrolled in this study. Patients were divided into underexcretion group (<3600 μmol/24h) and non-underexcretion group (≥3600 μmol/24h). The correlation between sUACR and 24-hour urinary uric acid excretion was analyzed by the Pearson’s correlations analysis. Receiver operation characteristic (ROC) curves were performed to assess the utility of sUACR for discriminating between underexcretion group and non-underexcretion group. Furthermore, the risk factors of uric acid underexcretion were evaluated using binary logistic regression analysis.Results:sUACR in the underexcretion group was significantly lower than the non-underexcretion group (p=0.0001). Besides, sUACR was positively correlated with 24-hour urinary uric acid excretion (r=0.4833, p<0.0001). Furthermore, ROC suggested that the area under the curve (AUC) of sUACR was 0.728, which was higher that of serum uric acid and creatinine. The optimal cutoff point of sUACR was 5.2312, with a sensitivity and specificity of 71.9% and 67.9%. Logistic analysis results revealed that decreased sUACR (<5.2312) was an independent risk factor of underexcretion of uric acid (OR =5.510, 95% CI: 1.952-15.550, P=0.001).Conclusion:sUACR is lower in gout patients with underexcretion of uric acid and may serve as a useful and convenient marker of assessing underexcretion of uric acid in gout patients.References:[1]Perez-Ruiz F, Calabozo M, Erauskin GG, Ruibal A, Herrero-Beites AM.

Objective: To compare the effectiveness after administration of Renalof to Kalkurenal and placebo in patient with renal calculus. Material & Method: We analyzed 30 patient with renal calculi less than or equal to 20 mm (2 cm) between January 2011 and March 2011. Patients were divided into 3 groups. Nine patients were treated with placebo, 8 patients were treated with Kalkurenal and the last 13 patients were treated with Renalof. After 30 days, we analyzed calcium and uric acid excretion for 24 hours and measured the stone with plain abdominal film and renal ultrasound. Results: There were decreased in excretion of calcium and uric acid all of patients but not significant statistically (p > 0,05) and there were significant decreased on stone measurement in patient treated with Renalof. Conclusion: Renalof  can be given as adjunct therapy for patient with renal calculi. Keywords: Calcium and uric acid excretion in urine 24 hours, stone measurement and stone surface area.

Introduction: Ulnar volar dislocation (UVD) is a very rare entity. Due to rarity of condition, usually, it’s misdiagnosed at emergency departments and management of this clinical entity is not well studied. Here, we report a case of UVD impressing diagnostic challenge, indication of treatment, and follow-up. Case Report: A 29-year-old man presented to orthopedic outpatient service with complaining of the right wrist pain. He had an assault history 3 days before. In the emergency department, he had been diagnosed as wrist sprain. Splint and pain killers were prescribed. Due to increase of pain, he admitted to orthopedics. He was diagnosed UVD. Under general anesthesia, joint was reduced with forced pronation maneuver. After 3 weeks immobilization period, magnetic resonance images revealed partial injury of triangular fibrocartilage complex then splint removed and rehabilitation initiated. Over than 24 months, he is doing well without movement limitation and wrist strength impairment. Conclusion: For prevention misdiagnosis of UVD, physical examination is very important. Forearm rotation limitation with pain in the wrist should be indicative for distal radioulnar joint injury. Physical examination should be supported with proper evaluation of suitable radiographs. After reduction of joint, magnetic resonance images give clues about ligamentous injury. Our case supports the importance of rigorous physical examination and evaluation of radiographs for wrist injury. In the presence of partial injury of ligaments, the condition can be treated with shorter periods of immobilization and early rehabilitation. Keywords: Wrist pain, ulnar volar dislocation, distal radioulnar joint, forearm rotation.

Tendon Ruptures

Fluoroquinolone antibiotics (such as ciprofloxacin, pefloxacin, ofloxacin, norfloxacin, temafloxacin, etc.) have recently been implicated in the etiology of Achilles tendinitis and subsequent tendon rupture. We report on a patient with bilateral partial Achilles tendon ruptures associated with ciprofloxacin therapy and present a review of the current literature on this increasingly recognized complication. Treatment with fluoroquinolones should be discontinued at the first sign of tendon inflammation so as to reduce the risk of subsequent rupture. Magnetic resonance imaging is useful in distinguishing between Achilles tendinitis and partial tendon rupture.

The authors previously confirmed the serum uric acid-lowering effects of the combination of glycine and tryptophan in subjects with mild hyperuricemia. This study examined whether combined supplementation with glycine and tryptophan suppressed the elevation in serum uric acid levels caused by purine ingestion and accelerated urinary uric acid excretion in subjects with lower urate excretion using a randomized, single-blind, placebo-controlled, crossover clinical trial design. Healthy Japanese adult males with lower urate excretion ingested water containing purines in addition to dextrin (placebo), tryptophan, glycine, or a glycine and tryptophan mixture. The combined supplementation with glycine and tryptophan significantly reduced the elevated serum uric acid levels after purine ingestion. Glycine alone and in combination with tryptophan significantly increased urinary uric acid excretion and urate clearance compared with the effects of the placebo. Urinary pH increased by the ingestion of the mixture. These results suggested that the improved water solubility of uric acid due to increased urinary pH contributed to the increase of urinary uric acid excretion.
