Spontaneous ruptures of the extensor mechanism of the knee are very rare. They tend to increase considerably in patients with metabolic diseases such as chronic renal failure, hyperparathyroidism, diabetes, gout, and systemic lupus erythematosus. The reported case regards a 48-year-old man with chronic, spontaneous and simultaneous quadriceps, and contra-lateral patellar tendon rupture. The patient suffered from chronic renal failure and for the past year from tertiary hyperparathyroidism. Ruptured tendons were repaired and both knee were evaluated monthly for the next 12 months. Good functional recovery was achieved on both knees without relapse. This case emphasizes the importance of long-term high parathyroid hormone level in the etiology of tendons ruptures.

Patients with gout referring to Chinese herbal medicine are not rare in China, and a great number of clinical trials on herbal medicine have been published. However, there has not been a systematic review to summarize the evidence of Chinese herbal medicine for gout. The aim of this study is to evaluate the evidence for the effectiveness and safety of Chinese herbal medicine for gout. We searched for randomized clinical trials on Chinese herbal medicine for gout till December 2012. Cochrane risk of bias tool was used to assess the methodological quality. RevMan 5.2 was used to synthesize the results. We included 57 trials involving 4,527 gout patients. The quality of trials was generally poor. No trial reported health-related quality of life in patients. There is not enough evidence showing that herbal medicine was statistically more effective than conventional medications in pain relief [mean difference (MD), -0.03; 95% confidence interval (CI), -0.06, 0.00], but herbal medicine combined with conventional medicines may have better effectiveness (MD, -0.33; 95% CI, -0.59, -0.07). Trials that reported function limitation relief found herbal medicine more effective than conventional medications (MD, -0.23; 95% CI, -0.32, -0.15). There was no evidence showing that herbal medicine prevents gout recurrence better. Twenty-five out of 41 trials, involving 23 different herbal prescriptions, found statistical significance in lowering serum uric acid level, and the overall effect from Chinese herbal medicine in inflammation relief is better than conventional therapies in 19 trials with 17 different prescriptions. The current data show that herbal medicine leads to fewer side reactions compared to conventional therapies [risk ratio (RR), 0.11; 95% CI, 0.08 to 0.15]. Chinese herbal medicine may have clinical effectiveness for functional recovery in patients with gout, and lead to a safe control of serum uric acid level and inflammation severity. Due to low quality of trials, trials with higher methodological quality and less heterogeneity are needed in the future.

Background: As a major antioxidant in serum, uric acid (UA) was once considered only as the leading cause of gout; however, recent studies have validated its neuroprotective role in ischemic stroke. Because the potential protective effects of UA in traumatic brain injury (TBI) remain largely unknown, this study investigated the role of UA in TBI in both clinical patients and experimental animals. Methods: In TBI patients, serum UA concentrations were measured within 3 days after injury. Clinical outcomes at discharge were classified according to the Glasgow Outcome Scale: good outcome (4-5) and poor outcome (1-3). Risk factors for good outcome were identified via backward logistic regression analysis. For the animal study, a controlled cortical impact (CCI) injury model was established in mice. These mice were given UA at different doses intraperitoneally, and subsequent UA concentrations in mouse serum and brain tissue were determined. Neurological function, oxidative stress, inflammatory response, neuronal maintenance, cerebral blood flow, and lesion size were also assessed. Results: The serum UA level was significantly lower in TBI patients who had a good outcome (P<0.01), and low serum UA was an independent predictor of good outcome after TBI (P<0.01; odds ratio, 0.023; 95% confidence interval, 0.006-0.082). Consistently, decreased levels of serum UA were observed in both TBI patients and CCI animals (P<0.05), whereas the UA concentration was increased in CCI brain tissue (P<0.05). Administration of UA further increased the UA level in brain tissue as compared to that in control animals (P<0.05). Among the different doses administered, 16 mg/kg UA improved sensorimotor functional recovery, spatial learning, and memory in CCI mice (P<0.05). Moreover, oxidative stress and the inflammatory response were inhibited by UA treatment (P<0.05). UA treatment also improved neuronal maintenance and cortical blood flow (P<0.05) but not lesion size (P>0.05). Conclusions: UA acted to attenuate neuronal loss, cerebral perfusion impairment and neurological deficits in TBI mice through suppression of neuronal and vascular oxidative stress. Following TBI, active antioxidant defense in the brain may result in consumption of UA in the serum, and thus, a decreased serum UA level could be predictive of good clinical recovery.
