[show abstract] [hide abstract]
ABSTRACT: We evaluated the effect of different syringe volume, needle size and sample volume on blood gas analysis in syringes washed with heparin. In this multi-step experimental study, percent dilution ratios (PDRs) and final heparin concentrations (FHCs) were calculated by gravimetric method for determining the effect of syringe volume (1, 2, 5 and 10 mL), needle size (20, 21, 22, 25 and 26 G) and sample volume (0.5, 1, 2, 5 and 10 mL). The effect of different PDRs and FHCs on blood gas and electrolyte parameters were determined. The erroneous results from nonstandardized sampling were evaluated according to RiliBAK's TEa. The increase of PDRs and FHCs was associated with the decrease of syringe volume, the increase of needle size and the decrease of sample volume: from 2.0% and 100 IU/mL in 10 mL-syringe to 7.0% and 351 IU/mL in 1 mL-syringe; from 4.9% and 245 IU/mL in 26G to 7.6% and 380 IU/mL in 20 G with combined 1 mL syringe; from 2.0% and 100 IU/mL in full-filled sample to 34% and 1675 IU/mL in 0.5 mL suctioned sample into 10 mL-syringe. There was no statistical difference in pH; but the percent decreasing in pCO2,, K+, iCa2+, iMg2+; the percent increasing in pO2 and Na+ were statistical significance compared to samples full-filled in syringes. The all changes in pH and pO2 were acceptable; but the changes in pCO2, Na+, K+ and iCa2+ were unacceptable according to TEa limits except fullfilled-syringes. CONDUSIONS: The changes in PDRs and FHCs due nonstandardized sampling in syringe washed with liquid heparin give rise to erroneous test results for pCO2 and electrolytes.Biochemia Medica 01/2012; 22(2):189-201. · 1.34 Impact Factor -

Article: Effect of levothyroxine replacement therapy on paraoxonase-1 and carotid intima-media thickness in subclinical hypothyroidism.
[show abstract] [hide abstract]
ABSTRACT: Paraoxonase-1 (PON-1) may play an important role in atherosclerosis. Atherosclerosis is an inflammatory disease and C-reactive protein is a marker for inflammation. The aim of this study was to determine serum PON-1 activity and high-sensitivity C-reactive protein (hs-CRP) levels and assess carotid intima-media thickness, a marker of early atherosclerotic changes, in patients with subclinical hypothyroidism. hs-CRP concentrations and PON-1 activity with respect to carotid intima-media thickness were evaluated in 38 subclinical hypothyroidism patients (normolipidemic, mean age: 49.79+/-10.04 years) before and after 3 months of stable euthyroidism and compared with those of 19 euthyroid normolipidemic healthy individuals (mean age: 49.95+/-8.12 years). At baseline, the patients with subclinical hypothyroidism had similar levels of PON-1 activity and hs-CRP and a similar lipid profile as the controls; however, the carotid intima-media thickness was greater than in the controls. Levothyroxine treatment had no effect on serum PON-1 activity and hs-CRP level, but it resulted in a significant reduction in carotid intima-media thickness in the subclinical hypothyroidism patients. PON-1 activity and hs-CRP levels did not significantly differ between subclinical hypothyroid patients and controls. Although levothyroxine treatment might have the potential to reverse the progression of atherosclerosis in subclinical hypothyroid patients, PON-1 activity and hs-CRP levels were not affected by this treatment. The reduction in carotid intima-media thickness was independent of the decrease in serum lipid profile or other variables.Medical science monitor: international medical journal of experimental and clinical research 01/2010; 16(1):CR41-7. · 1.70 Impact Factor -
Article: Prospective comparison of tissue trauma after laparoscopic hysterectomy types with retroperitoneal lateral transsection of uterine vessels using ligasure and abdominal hysterectomy.
[show abstract] [hide abstract]
ABSTRACT: The aim of this study was to evaluate the level of tissue trauma after laparoscopic and total laparoscopic hysterectomy with retroperitoneal lateral transsection of uterine vessels using ligasure as compared with abdominal hysterectomy. A total of 45 women with various indications for hysterectomy were randomized into laparoscopic hysterectomy, total laparoscopic hysterectomy and abdominal hysterectomy. Laparoscopic and total laparoscopic hysterectomy with retroperitoneal lateral transsection of uterine vessels was performed by four-puncture laparoscopy and pre-, postoperative and postoperative 24th hour levels of interleukin-6 (IL-6) and C-reactive protein (CRP), the mean operative time, drop in hemoglobin concentration, weight of removed uterus, VAS scores, hospitalization period and major and minor operative complications were analyzed prospectively. CRP and IL-6 levels were significantly higher in the abdominal hysterectomy group compared to either laparoscopy groups at the postoperative 24th hour. There were no significant differences in the levels of CRP and IL-6 between the two laparoscopy groups. The longest operative times were observed in the total laparoscopic hysterectomy group. Laparoscopic surgery causes less tissue trauma than the conventional open surgery; however, we observed no difference between the laparoscopic hysterectomy groups concerning the postoperative inflammatory response. We may prefer laparoscopic hysterectomy instead of total laparoscopic hysterectomy under suitable conditions, since laparoscopic hysterectomy causes the same level of tissue trauma as total laparoscopic hysterectomy, but has the advantage of a significantly shorter operative time. Meanwhile, hysterectomy done by laparoscopy with retroperitoneal lateral transsection of uterine vessels using ligasure is an effective and safe procedure.Archives of Gynecology and Obstetrics 05/2008; 277(4):325-30. · 1.28 Impact Factor -
Article: Plasma thiobarbituric acid-reactive substance levels in subclinical hypothyroidism.
[show abstract] [hide abstract]
ABSTRACT: The purpose of this study was to determine thiobarbituric acid-reactive substance (TBARS) levels in subclinical hypothyroidism and to examine the effect of levothyroxine replacement on TBARS levels. A cohort of 28 female patients with subclinical hypothyroidism and 24 healthy controls were enrolled in this study. The levels of plasma TBARS, serum lipids, and high-sensitive C-reactive protein (CRP) in patients with subclinical hypothyroidism at baseline and after achieving euthyroid state by levothyroxine were assessed. TBARS levels of the patients were similar to those of the control group in the subclinical hypothyroid state and after restoration of euthyroidism by levothyroxine replacement. TBARS levels decreased after levothyroxine treatment, but did not reach statistical significance. There was no significant correlation between TBARS, lipid and CRP levels. Serum CRP levels were higher in subclinical hypothyroidism (4.28 +/- 0.9 mg/l) than in the control group (1.95 +/- 0.34 mg/l) and the difference was statistically significant (p = 0.03). After achieving euthyroid state, CRP levels decreased significantly in patients with subclinical hypothyroidism from 4.28 +/- 0.9 to 2.32 +/- 0.6 mg/l (p = 0.006). Our findings suggest that there is no significant alteration of plasma TBARS levels neither in subclinical hypothyroid state nor after achieving euthyroid state. Serum CRP level is higher in patients with subclinical hypothyroidism than in the control group. Normalization of thyroid state seems to effectively reduce serum CRP levels in subclinical hypothyroidism without any correlation with TBARS activity.Medical Principles and Practice 02/2007; 16(6):432-6. · 0.89 Impact Factor
