    OBJECTIVE: To review the clinical characteristics of patients with isolated fallopian tube torsion (IFTT). STUDY DESIGN: We conducted a retrospective study of a consecutive series of IFTT cases presenting at 2 tertiary referral centers. All patients underwent laparoscopic assessment, and the fallopian tube and its ligamentous support were gently untwisted to assess ischemic lesions. Patients were classified based on the following 3 criteria: complete recovery (Group A), partial recovery (Group B), and without any recovery (Group C). RESULTS: Our series consisted of 9 patients. Group A (2 cases) and Group B (5 cases) were managed conservatively. Two patients were assigned to group C and underwent laparoscopic salpingectomy. During early postoperative period, in the conservatively managed group 4 patients underwent hysterosalpingography examination, and both fallopian tubes were found to be patent. One of these 4 patients had a spontaneous pregnancy and delivered a healthy infant, and another patient had a miscarriage at 6 weeks' gestation. Imaging revealed no pathological findings in the remaining 3 virgins in the conservatively managed group. No infections, peritonitis, thromboembolic events, or other complications occurred during the follow-up period. CONCLUSION: Conservative management of IFTT can be considered a safe option, even if little evidence of recovery is observed after detorsion.

    Experimental investigation of impact of addition of bioethanol in different biodiesels, on performance, combustion and emission characteristics
    (KOREAN SOC MECHANICAL ENGINEERS, 2017) Celik, Mehmet; Ors, Ilker; Bayindirli, Cihan; Demiralp, Mehmet
    This study includes the experimental evaluation of performance, combustion and emission characteristics of cottonseed and grapeseed biodiesels and blends containing bioethanol in a diesel engine with different engine speeds at full load. Addition of bioethanol into the fuels (diesel and biodiesel) used by diesel engines is considered an effective solution. The study observed that the cetane number, viscosity, density and lower heating value of fuel were reduced after the addition of bioethanol in all engine speeds. While the brake power and torque values were reduced as the rate of bioethanol increased, additionally specific fuel consumption, maximum cylinder pressure, heat release and ignition delay also increased. Reviewing the emission results, carbon monoxide (CO) and total hydrocarbon (THC) emissions increased as bioethanol rate increased, nitrogen oxides (NOx) and smoke emissions were reduced.
