Analysis of factors on voice quality in thyroidectomy patients.

OBJECTIVE: Vocal cord paralysis (VCP) is a serious complication in thyroidectomy operations; however, its management remains unclear. The present study evaluated the voice parameters of patients who underwent surgery using Intraoperative Neurophysiologic Monitoring (IONM). PATIENTS AND METHODS: A total of 52 patients (41 females and 11 males) who underwent a total thyroidectomy operation were evaluated using objective and subjective voice analysis examinations before and after surgery. Acoustic parameters, such as Fundamental Frequency (F0), Shimmer, Jitter, Noise-to-Harmonic ratio (NHR), and aerodynamic parameters, including S/Z ratio and maximum phonation time (MPT), were analyzed. Objective findings, including the VHI-10 (Voice Handicap Index) and V-RQOL (Voice-Related Quality of Life), were also analyzed. The relationship between voice parameters and IONM values was investigated. RESULTS: The objective analysis (acoustic and aerodynamic parameters) showed no difference (p>0.05). However, the subjective analysis, which involved the VHI-10 and V-RQOL measures, revealed a significant difference before and after the operation (p<0.05). The Spearman correlation analysis showed that the NHR postoperative 1st-month parameter negatively correlated (rho=-0.317, p<0.059), while the F0 postoperative 6th-month parameter positively correlated (rho=0.347) with the amplitude difference before and after dissection (Right R2-R1 difference) for the right RLN measured in IONM. CONCLUSIONS: Patients who are planning to undergo a thyroidectomy procedure should undergo voice assessment during both the preoperative and postoperative periods. IONM could improve voice quality outcomes.

Association between red cell distribution width and mean platelet volume with appendicitis: a myth or a fact?

OBJECTIVES: The aim of our study was to identify if there was a relation between red cell distribution width, mean platelet volume, platelet distribution width, leukocyte count and thrombocyte count at the time of presentation to hospital and acute appendicitis. BACKGROUND: Acute appendicitis is one of the most common surgical emergencies. Misinterpretation of symptoms and findings in acute appendicitis may lead to removal of normal appendix and delayed diagnosis can result in perforation and peritonitis. Many studies tried to delineate the relation between acute appendicitis and laboratory findings. Latest studies focused on components of complete blood count such as red cell distribution width and mean platelet volume. METHODS: This was a retrospective clinical study that enrolled 638 patients with abdominal pain and open appendectomy for acute appendicitis. Complete blood count results including red cell distribution width were retrieved from medical charts of patients and analyzed. RESULTS: There was no statistically significant difference between appendicitis, non pathological appendix and perforated appendicitis in terms of red cell distribution width or other blood count components except leukocyte level. CONCLUSION: Despite current findings in medical literature indicating predictive value of red cell distribution width in acute appendicitis; its utility for differential diagnosis might be overestimated (Tab. 1, Ref. 22).

Red cell distribution width, gamma glutamyl transpeptidase and anticoagulant use affect mortality in acute arterial mesenteric ischemia.

BACKGROUND: Despite advances in surgery and intensive care, mortality in acute mesenteric ischemia remains between 50% and 90%. In this study, we evaluated factors affecting mortality in acute arterial mesenteric ischemia. METHODS: This is a retrospective cohort study involving 73 patients with an initial diagnosis of arterial acute mesenteric ischemia admitted to Ankara Numune Teaching Hospital between January 2008 and December 2013. We retrospectively collected data about demographic variables, co-morbidities, medications, extent of surgical resection, laboratory values, pathology results and outcome. RESULTS: The mean age of the patients was 69.3±12.6. Thirty one patients were female (42.46%) and 42 (57.53%) were male. We divided the patients into two groups: Group 1 (n=40); those who died and Group 2 (n=33); those who were discharged. In multivariate analysis of high gamma glutamyl transpeptidase and red cell distribution width levels, the presence of anticoagulant use was statistically significant (p<0.05) in favor of Group 1. CONCLUSION: High red cell distribution width and gamma glutamyl transpeptidase levels and anti-coagulant use are factors affecting mortality in arterial acute mesenteric ischemia. The assessment of these variables could help predict the extent of arterial acute mesenteric ischemia and the mortality associated with it.
