5 to 2.7 cm. There were no demographic

differences between women with and without visible Bartholin gland cysts.

CONCLUSION: Bartholin gland cysts occur in 3% of adult women. The cysts affect women of broad ranges of age and parity. Women with visible Bartholin gland cysts are demographically similar to women without cysts on pelvic imaging. (Obstet Gynecol 2012; 120: 798-802) DOI:http://10.1097/AOG.0b013e3182699259″
“The present study evaluated the pharmacokinetics of methotrexate (MTX, CAS 59-05-2) and 7-hydroxymethotrexate (7-OHMTX, CAS 5939-37-7) in children with acute lymphoblastic leukemia (ALL) with particular interest devoted to the renal excretion at AZD7762 the steady-state and to the relationships between total (CL) and renal clearances (CL(R)) of both compounds. Ten children (seven girls) aged 8.5 years (2.9-16) years with standard or medium-risk ALL received four 24-h i. v. infusions of high-dose MIX (HDMTX, 5 g/m(2)) with leucovorin (CAS 58-05-9) rescue according to the ALL-BFM-95 protocol. MIX and 7-OHMTX were

assayed in plasma and urine by high-performance liquid chromatography. At the steady-state, the clearance (CL) of MIX (6.28 +/- 2.79 l.h(-1)) was correlated with its CL(R) (r(s) = 0.79, p < 0.0001) which accounted for 61 % (SD 26%) of the former. There were weak correlations between pretreatment values of creatinine clearance calculated using Schwartz’s formula and the drug’s CL (r(s) = 0.30, p < 0.05) or CL(R) (r(s) = 0.41, p < 0.02). In contrast, the CL(R) accounted for only 26% (SD 15%) of the metabolite’s VX-809 inhibitor CL which was estimated assuming 10% selleck chemicals llc conversion of MIX to 7-OHMTX. The CL values of both compounds were highly correlated (r(s) = 0.86,

p < 0.0001). The CL(R) of the parent compound was on the average 9-fold higher (range: 3.5- to 17-fold) and was strongly correlated with the CLR of the metabolite (r(s) = 0.87, p < 0.0001). The ratio 7-OHMTX/MTX of urinary concentrations was between 2.4 and 9.8% with the mean value of 4.1 %.

This study suggests that during the 24-h i. v. infusions of HDMTX to children with ALL, the exposure of patients to 7-OHMTX can be reasonably well predicted from the knowledge of MTX concentrations. The steady-state renal CLs, total CLs as well as urinary concentrations of the parent compound and metabolite are highly correlated and the correlation of plasma concentrations is moderate. Therefore, it is unlikely that simultaneous evaluation of 7-OHMTX and MTX steady-state concentrations could improve the predictive performance of the latter towards the response or the risk of complications, although future larger studies should verify this conclusion.”
