Objectives: This study aims to evaluate the relationship between serum uric acid levels and renal functions in asymptomatic subjects who had occupational lead exposure, particularly for shorter durations whereby saturnine gout has also been discussed. Patients and methods: In this retrospective study, files of 100 males (mean age 34.5±5.9 years; range, 21 to 47 years) with occupational risk for lead exposure and 100 healthy male controls (mean age 34.47±5.8 years; range 21 to 47 years) were reviewed. Demographic characteristics of the subjects and laboratory test results were recorded from the files. Creatinine clearance and 24-hour urinary creatinine were measured in the lead-exposed group. Results: In the lead-exposed group, mean serum uric acid level was higher than those of the control group (p<0.001). Lead exposure time was negatively correlated with 24-hour urinary creatinine levels (r= -0.373, p<0.001). In addition, serum uric acid levels were positively correlated with serum creatinine levels (r=0.412, p<0.001) in the exposed group. Six patients had hyperuricemia (serum uric acid level >6.8 mg/dL) in the lead-exposed group; however, all subjects' serum uric acid level was lower than 6.8 mg/dL in the control group (p=0.029). Although 22 subjects had higher uric acid levels than 6.0 mg/dL in the lead-exposed group, only one control had higher uric acid level than 6.0 mg/dL (p<0.001). Conclusion: In light of our results, we may conclude that workers with lead exposure have higher frequency of hyperuricemia and higher serum uric acid levels than those of the control group. Therefore, we may imply that higher serum uric acid levels may be associated with renal impairment in lead-exposed subjects even in the earlier stages of exposure. [ABSTRACT FROM AUTHOR]

A letter to the editor is presented in response to the article "Coexistenee of Behcet's Disease (BD) and Ankylosing Spondylitis" by C. Celik and colleagues in the September 2011 issue.

We aimed to show the effect of osteoporosis on sleep quality in 59 postmenopausal women. The participants' bone-mineral density levels were measured by dual-energy X-ray absorptiometry (DEXA). According to their DEXA results, participants were divided into two groups as osteoporotics and controls. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality. Fourteen osteoporotic women (43.8%) and four controls (14.8%) were 'poor' sleepers ( p < 0.05). Postmenopausal women with osteoporosis scored greater on the 'sleep latency' and 'sleep duration' components of PSQI than controls. According to the findings of our study, osteoporosis is a risk factor for poor sleep quality in postmenopausal women. [ABSTRACT FROM AUTHOR]

The article describes the case of a 49-year-old man who was presented to the clinic with pain, acute-onset swelling and local erythema in his right big toe. Topics discussed include the findings from physical examination like elevated serum C-reactive protein, the erosion of the proximal phalanx as revealed through ultrasonography and the diagnosis of gout, which is said to be the most common forms of inflammatory arthritis characterized by the crystallization of uric acid.
