    Bruxism: is it a new sign of the cardiovascular diseases?
    (Verduci Publisher, 2011) Atilgan, Z.; Buyukkaya, R.; Yaman, F.; Tekbas, G.; Atilgan, S.; Gunay, A.; Palanci, Y.
    Aim: To determine the relationship between bruxism and cardiovascular diseases. Materials and Methods: 120 patients who referred to the Dentistry Faculty with the complaint of bruxism were selected. All patients gave informed consent for participation in the study. All of the patients were examined and bruxism was classified. And also these were examined by B-mode ultrasound to measure the Intima Media Thickness (IMT) at the far wall of the common carotid artery. A wide range of vascular risk factors including age, gender, body mass index, and previous history were surveyed. Spearman correlation analysis was performed to ascertain quantitative comparison, Mann-Whitney U and Kruskal-Wallis test were used for comparison of means Results: There were 66 (55%) male and 54 (45%) female patients, with a female to male ratio of 1/1.2. The mean age was 35.6 +/- 1,25 years (range 18-65 years). In the analysis of bruxism classification and IMT there was a statistical significance between bruxism classification subgroup 1, 2, 3 and IMT. There was no statistical significance between bruxism classification Subgroup 4 and IMT due to the small number of the patients (n=12). Conclusions: Stressful situations can cause both bruxism and cardiovascular disease such as coronary artery diseases, hypertension, arrhythmias, cardiomyopathy. The statistical analysis supported this hypothesis. However, we need to new studies with large number of samples to confirm this hypothesis. Clearly, future studies in this field will need to take into consideration the influence of the following variables: age, use of medication or drugs, smoking habits, and other sleep disorders.

    Frequency of respiratory function disorders among dental laboratory technicians working under conditions of high dust concentration
    (Verduci Publisher, 2013) Abakay, A.; Atilgan, S.; Abakay, O.; Atalay, Y.; Guven, S.; Yaman, F.; Palanci, Y.
    BACKGROUND AND OBJECTIVES: Dental laboratory technicians (DLTs) have much exposure to mineralogical dust that may have adverse effects on their lung health. The aim of our study was to investigate occupational dust exposure, and to determine the frequency of respiratory function disorders and radiologic abnormalities among DLTs. MATERIALS AND METHODS: The study enrolled 94 DLTs who were exposed to dust in dental laboratories and 94 control subjects. Dust concentrations in the workplaces were measured. RESULTS: The mean age of DLTs was 30.70 +/- 9.84 years. No significant difference was found between the DLTs and the control groups for age or smoking status (p > 0.05). Spirometric values for the DLTs were found to be lower than the control group (p < 0.05). The mean working period for DLTs was 9.19 +/- 5.9 years. The pulmonary function test results for the DLTs showed that 65.9% had a normal pattern, 22.4% were restrictive, and 11.7% showed obstructive type pulmonary function disorder. Negative correlations were found between the working period time and Forced Expiratory Volume in 1 second in the DLTs (R = -0.675 p = 0.000). Negative correlations were also found between working period time and Forced Vital Capacity in the DLTs (R = -0.720 p = 0.000). All DLTs had chest X-rays and 16 (17%) of them showed radiological pneumoconiosis. CONCLUSIONS: This study showed a negative association between level of respiratory function and working period in DLTs.

    Relationship between 18 FDG PET-CT findings and the survival of 177 patients with malignant pleural mesothelioma
    (Verduci Publisher, 2013) Abakay, A.; Komek, H.; Abakay, O.; Palanci, Y.; Ekici, F.; Tekbas, G.; Tanrikulu, A. C.
    BACKGROUND AND OBJECTIVES: Malignant pleural mesothelioma (MPM) is a fatal malignancy. Radiological imaging is necessary for the diagnosis, staging, and clinical management of patients with MPM. The 18 fluorodeoxyglucose positron emission tomography (18 FDG-PET) scan has proven useful in preoperative staging and as a prognostic tool in MPM. We aimed to investigate the relationship between the pre-treatment 18 FDG PET/CT results, together with other known clinical parameters, and the survival of patients with MPM in our region. PATIENTS AND METHODS: A retrospective analysis was performed on the data of 177 patients with MPM between April 2007 and April 2011. Pretreatment 18 FDG PET/CT scans were done on all patients. Survival time was calculated by the Kaplan-Meier method. RESULTS: The mean age was 55.40 years. There were 56% male patients and 44% female patients. The mean survival time was 11 months from time of diagnosis. According to multivariate analysis results, being of male gender increased the poor prognosis 5.30 times, a Karnofsky performance score (KPS) < 60 increased a poor prognosis 2.18 times, being on best supportive care increased a poor prognosis 25.40 times, the stage III-IV increased a poor prognosis 11.13 times, and a level of maximum standardized uptake value (SUVmax) > 5 increased a poor prognosis 4.34 times. CONCLUSIONS: MPM remains a fatal prognosis. Significant predictors of survival include KPS, stage of disease, gender, treatment regimen and level of SUVmax. An understanding of the importance of these markers for MPM prognosis should allow targeted treatments to be developed.

    Sensitivity and specificity of terminal latency index and residual latency in the diagnosis of carpal tunnel syndrome
    (Verduci Publisher, 2011) Uzar, E.; Tamam, Y.; Acar, A.; Yucel, Y.; Palanci, Y.; Cansever, S.; Cevik, M. Ugur
    Objectives: Traditionally, nerve conduction study (NCS) are used to diagnose carpal tunnel syndrome (CTS). However, no NCS has the sufficient sensitivity or specificity values to diagnose CTS by itself. Median terminal latency index (mTLI) and median residual latency (mRL) are parameters that calculated to identify abnormalities in distal segments of the median motor nerve. There are few studies on mTLI and mRL in the diagnosis of CTS. The objective of this study was to examine the sensitivity and specificity of mTLI and mRL together with NCS in the diagnosis of CTS. Patients and Methods and Results: The diagnostic sensitivity of mTLI and mRL were calculated and compared with the conventional NCS. Sensitivity values of electrophysiological findings were as follows: median distal sensory latency (mDSL) 91.5%, fourth finger median-ulnar sensory (M4-U4) latency difference 91.5%, mTLI 90.1%, median sensory nerve conduction velocity (mSNCV) 87.4%, and median motor distal latency (mMDL) 68.6%. Specificity values of electrophysiological findings in those with carpal tunnel syndrome were mSNCV 98.6%, mMNCV (median motor nerve conduction velocity) 98.6%, median motor wrist muscle action potential amplitude 98.6%, median sensory nerve action potential amplitude 97.4%, mSDL 97.3% and M4-U4 (fourtm finger median-ulnar sensory peak latency difference) latency difference 97.3%. In all CTS patients with long mMDL values, mTLI was found to be lower, however in 22 CTS patients (22.6%) with normal mMDL, mTLI was also found to be lower. Compared with mMDL, the sensitivity of mTLI in the diagnosis of CTS was found to be higher but its specificity was lower. No differences were found in the sensitivity and specificity of mRL and mMDL. The electrophysiological findings with the highest sensitivity and specificity in diagnosing CTS among conventional NCS were mSDL, M4-U4 peak latency difference and mSNCV. Conclusions: It was concluded that mTLI and mSDL can complete each other in the detection of abnormalities of sensory and motor fibres in the diagnosis of CTS.

    Sigmoid colon torsion: mortality and relevant risk factors
    (Verduci Publisher, 2013) Onder, A.; Kapan, M.; Arikanoglu, Z.; Palanci, Y.; Gumus, M.; Aliosmanoglu, I.; Aldemir, M.
    INTRODUCTION: Sigmoid volvulus is an important acute intestinal obstruction, leading to high mortality and requiring urgent operation. The purpose of this study is to analyze risk factors for mortality in patients that were operated on due to sigmoid volvulus at our Department. MATERIALS AND METHODS: The retrospective study included 158 patients, who were operated on due to sigmoid volvulus between January 1994-December 2010, in terms of age, gender, complaints at admission, physical signs, period of symptoms before admission, associated diseases, laboratory and radiological parameters, hospital stay, morbidity, and mortality. RESULTS: The study consisted of 135 men (85.4%) and 23 women (14.6%), with a mean age of 62.54 years. Cardiovascular disease and respiratory disease were present in 34 (21.5%) and 42 (26.6%) patients, respectively. Urgent operation was undertaken in 125, while 33 received elective surgery. Abdominal distension and pain was evident in all the patients. Generalized tenderness was detected in 58.2%, while 70.9% had hyperactive bowel sound with tympanism. Plain radiograph revealed an impression of omega ans in all patients, while free air was detected in 11.4% of them. Risk factors for mortality included age (p = 0.008), delayed admission (p = 0.001), cardiovascular and respiratory diseases (p = 0.001), fluid-electrolyte imbalance (p = 0.001), presence of necrosis (p = 0.001), and major contamination (p = 0.001). Wound infection and intraabdominal abscess were more common in patients that developed mortality (p = 0.001 and p = 0.002). CONCLUSIONS: Complications like wound infection and intraabdominal abscess are more frequent in the patients with the risk of mortality. Delayed admission results in higher risk of mortality. Mortality rates can be reduced by early admission, preoperative intensive resuscitation, suitable antibiotics, and emergent and viable surgery.
