  ABSTRACT: Our objective was to analyze the advantages of the percutaneous nephrolithotomy in oblique supine decubitus compared to the prone and dorsal supine position. In 87 patients diagnosed with urolithiasis (495.5-530.8 mm(2)), percutaneous nephrolithotomy (PNL) was performed from 2000 to 2011. The patients were divided into three groups: Group A, 32 patients, PNL in the prone decubitus position; Group B, 24 patients, PNL in the dorsal supine position; Group C, 31 patients, PNL in the oblique supine position. We analyzed intraoperative parameters, complications, and results among the three groups. The three procedures were performed with a single access, 24-30 Ch. No statistically significant differences were found among the three groups regarding the patients' characteristics, or the morphology or size of the kidney stone treated. The operation time was shorter in the cases of PNL in dorsal supine and oblique supine compared to the prone position. The complication rate was very similar in the three groups. The main advantage of the PNL in oblique supine compared to the dorsal supine was that the puncture could in all cases be directed by ultrasonography, with greater precision, more safety, and more control of the percutaneous renal access. The oblique supine decubitus position is a safe position for the percutaneous treatment of urolithiasis and it becomes easier when the puncture is guided by ultrasound.

  ABSTRACT: Some autoimmune conditions have been associated with reduced vitamin D levels, including systemic lupus erythematosus, rheumatoid arthritis, diabetes mellitus, and multiple sclerosis. The main objective of this study was to analyze the 25-hydroxyvitamin D (OHD) status of patients with psoriasis in comparison with control subjects without this disease. This case-control study included 86 patients (43 with psoriasis and 43 age- and sex-matched control subjects) from the outpatient clinic of our hospital dermatology department in Granada, Spain. All patients and control subjects were studied during one 4-week period to avoid seasonal variations in vitamin D levels. Serum 25-OHD levels were significantly lower in psoriatic patients than in control subjects even after adjusting for confounding factors in a multivariate analysis (odds ratio 2.89, 95% confidence interval 1.02-7.64, P < .03 for vitamin D insufficiency). Low 25-OHD levels were negatively associated with C-reactive protein (inflammatory activation marker) and body mass index in multiple linear regression analysis. Psoriatic patients with body mass index greater than or equal to 27 kg/m(2) had a higher risk of 25-OHD insufficiency (sensitivity of 82.3% and specificity of 51.7%). Further studies with larger numbers of patients are required to analyze the pathogenic mechanisms underlying the relationship between 25-OHD deficiency and psoriasis. The 25-OHD values are significantly lower in psoriatic patients than in control subjects. Low 25-OHD levels are negatively associated with C-reactive protein, an inflammatory activation marker, and with obesity. Psoriatic patients with a body mass index of 27 or more are likely to have vitamin D insufficiency.
