    Short-term effects of montelukast in stable patients with moderate to severe COPD
    Celik, P; Sakar, A; Havlucu, Y; Yuksel, H; Turkdogan, P; Yorgancioglu, A
    This study aims to investigate the possibility of additional value of leukotriene receptor antagonist (LTA) on dyspnea score, arterial blood gases (ABG), pulmonary function tests (PFTs), and quality of life (St. George QoL) in chronic obstructive pulmonary disease (COPD) patients. In this randomized, prospective, single-blind, and controlled study, 117 non-reversible COPD patients defined by global initiative for chronic obstructive lung disease (GOLD) criteria were randomized to receive ipratropium bromide, formoterol and montelukast (n:58, montelukast group) or ipratropium bromide and formoterol (n:59, control group) after a 2-week run-in period. There was no significant demographic difference between the two groups (P > 0.05). Baseline ABG, PFT, visual analoque scores r(VAS), and QoL scores were obtained and at first month and second month, PFT, VAS, and QoL scores were repeated and ABG was obtained at second month and the values were compared with baseline values. As the result of the comparision, there was significant increase in vital capacity, FVC, FEV1, VAS, and PaO2 parameters (P < 0.05), and a significant decrease in the QoL scores (P < 0.05) in the montelukast group. These parameters did not show any difference in the control group (P > 0.05). Sputum samples that could be obtained in 24 of the COPD patients were evaluated and in the montelukast group, there was a decrease in neutrophitic activity after treatment (n:13) (P <= 0.059). These results suggest that LTA that is used additionally in routine treatment protocol can produce additive improvement on PFr, dyspnea score and especially QoL in patients with stable COPD and for these reasons, LTA may be taken into account when there is need for an additional anti-inflammatory treatment in COPD patients.

    Effect of adhesion barrier (interceed TC7) on two-stage orchidopexy operation
    Genc, A; Taneli, F; Yilmaz, O; Turkdogan, P; Arslan, OA; Sencan, A; Taneli, C
    Objective: In two-stage orchidopexy, adhesions formed after the first stage usually cause difficulty during the second operation and may even lead to injury to the testis itself or to the spermatic cord. We investigated whether the use of adhesion-preventing barriers in the abdominal or pelvic region during surgery could lessen adhesions formed during two-stage orchidopexy and thus ease dissection. Material and Methods: The study subjects comprised 21 male, albino, 30-day-old Wistar rats that were divided into three equal groups. In Group 1, the right testes were enveloped in adhesion barriers after dissection and sutured to the inguinal canal. In Group 2, the right testes were sutured to the inguinal canal without the barriers. In Group 3 (sham-operated group), all testes were dissected but no suturing was performed. Rats were sacrificed after 21 days and the ipsilateral testes were harvested. Results: Dissection of barrier-enveloped testes was relatively easy; however, no significant ( p < 0.535) difference was seen in adhesion scores between Groups 1 and 2. Total tissue collagen was estimated by means of the hydroxyproline content. Tissue hydroxyproline levels were 16.04 +/- 8.58, 13.20 +/- 6.34 and 14.71 +/- 5.51 mu g/mg wet tissue in Groups 1 - 3, respectively and these differences were not significant. The histopathologic evaluation revealed significant differences only in the thickness of the tunica albuginea in Groups 1 and 2 (110.0 +/- 30.0 vs 77.1 +/- 21.3 mu m, respectively; p < 0.038). Conclusion: The adhesion scores and the biochemical and histopathological examinations showed that an adhesion barrier is not beneficial in two-stage orchidopexy.
