Yeliz K?l?n?, Sedat ?etiner
Open Journal of Stomatology (OJST) , 2014, DOI: 10.4236/ojst.2014.410065
Abstract: Giant sialoliths larger than 20 mm are rare. The surgery has to be performed with the minimally invasive method in order to avoid the morbidity associated with the surgical techniques. In this report the surgical removal of a giant sialolith of 25 mm by using diode laser is described. A 57-year-old female was presented with a firm mass in the anterior part of the left side of the floor of the mouth. Following the clinical and radiological examination, the left submandibular duct sialolith was diagnosed. The diode laser was used with a power setting of 810 nm of wavelength, 4.0 W of power, 0.5 ms continuous wave and 1000 Hz of frequency for the incision. The giant sialolith was adequately removed under local anesthesia. The procedure was well-tolerated. The wound healing was uneventful in the postoperative period. By the 10th day after surgery the patient had no complaints and the salivary flow was normal. It was concluded that the use of 810-nm diode laser application is a safe and useful technique. Due to the excellent cutting and coagulation ability, there is a low complication rate, making it an appropriate alternative for this type of surgical procedure.

Abstract: Aim. This study aims to investigate the possible role of H. pylori as a cause of laryngeal squamous cell carcinoma. Method. This controlled study was performed with 31 consecutive laryngeal cancer and 28 cancer-free patients who underwent direct laryngoscopy and biopsy of laryngeal lesions. To document the previous H. pylori infection, serological analysis of the antibody titers was done. Immunohistochemical analyses were applied to the tissue samples. Results. Serology was found positive at the 90.3% of the laryngeal cancer patients and 96.4% of the benign group. There were no statistically significant differences between the two groups ( ). Immunohistochemical analysis results were determined as negative at all of the specimens of laryngeal cancer patients and patients with benign lesions. Conclusion. There were no signs of colonization of H. pylori in laryngeal tissues of both groups' patients. It is thought that no relationship exists between the H. pylori infection and laryngeal squamous cell carcinoma. 1. Introduction Laryngeal squamous cell carcinoma (LSCC) is one of the common cancers of the upper aerodigestive system. It accounts for 25% of all the cancers of head and neck and 2-3% of the cancers of the whole body [1]. Tobacco is the most important risk factor for the LSCC. The other risk factors might be some viruses, bacteria, diet type, radiation exposure, gastroesophageal reflux, occupation, and genetical inheritance [2]. H. pylori, a helical shaped gram-negative microaerobic bacterium which was described as a type 1 carcinogen by the International Agency for Research on Cancer Working Group (IARC-1994), is related to gastric cancer and MALT lymphoma [3, 4]. H. pylori has also been shown in the oral cavity, dental plaques, and saliva [5]. The existence of H. pylori in the oral cavity and stomach can indicate the colonization of the bacteria in the laryngeal mucosa. It is suggested that H. pylori might play a role in the development of laryngeal cancer by forming chronical inflammation and raising the exposure to the carcinogens by destroying mucosal and immune barriers. There are several studies investigating the relationship between H. pylori and laryngeal cancer, the results of which still show conflict about the subject [6–12]. The aim of the present study is to investigate the existence of H. pylori in the laryngeal specimens of the patients with the diagnosis of LSCC and to make a comparison with the patients with benign larynx pathologies. 2. Patients and Method A total of 59 patients with laryngeal pathologies were enrolled in the

Abstract: This research is an attempt to validate how glu-cose-insulin dynamic mathematical model facilitate to identify the root causes for hypoglycaemia. The purpose is to determine whether increased insulin sensitivity or increased insulin secretion causes post- prandial hypoglycemic (PPH) response, by linking experimental patient data with dynamic mathematical model. For this purpose two groups, as hypoglycemic Group 1 and non-hypoglycemic Group 2, each of which consists of 10 people, are formed. The oral glucose tolerance test (OGTT) is carried out for each person in the groups by measuring plasma glucose and insulin concentrations at every 30 minutes for a period of 5 hours. To distinguish the actual cause of hypoglycemia, the glucose minimal dynamic model is used. The model is executed in MATLAB platform using patient data and the results showed that insulin secretion is assumed to be the potential root cause for the hypoglycemia.

Abstract: Objective: To compare the vaginoscopic “no touch” approach to diagnostic outpatient hysteroscopy without anesthesia with traditional diagnostic office hysteroscopy after intracervical injection of prilokaine hydrochloride 2% in terms of pain perception and feasibility. Material and Methods: A total of 92 women undergoing diagnostic hysteroscopy were included in the study and were randomized, to one of two treatment groups. Forty-eight women underwent hysteroscopy without speculum, tenaculum, or anesthesia. Forty-four women received intracervical anesthesia with 10 mL of 2% prilocaine hydrochloride solution injected at two sites (3:00 and 9:00 positions) and underwent traditional hysteroscopy. Hysteroscopy was performed using a rigid 3.7-mm hysteroscope and a medium of 0.9% saline. The image was transmitted to a screen visible to the patient. A visual analog scale (VAS) consisting of a 10-cm line was used to assess the intensity of pain experienced during and after the procedure. Satisfaction was assessed by VAS at three different times during the procedure (Stage I: insertion of speculum, tenaculum placement, intracervical block for the traditional hysteroscopy group and insertion of hysteroscope into the vagina, vaginoscopy for the no touch method, Stage II: passage through internal cervical os, Stage III: observation of the uterine cavity and Stage IV: 15 minutes later, after hysteroscopy). Results: The mean pain score was significantly lower at Stage I in the no touch group (p<0.01). In five of the patients in no touch group (10.4%), hysteroscopy were unsuccessful because of cervical stenosis. Failure rate was not statistically significant in two groups (p>0.05). Conclusion: Patients reported significantly less pain with no touch method at the vaginoscopy compared with patients undergoing the traditional procedure with tenaculum placement and intracervical anesthesia. Both of the methods have had similar pain scores during the rest of the procedures and 15 minutes after the procedure with comparable failure rates. No touch method can therefore be considered as a useful hysteroscopic technique.

Abstract: Objectives: Staphylococci were most prominent factors that responsible for skin, soft tissue and foreign body infections.Gaining resistance to methicillin and various antibiotics in these microorganisms over the years increased morbidityand mortality, especially in hospitalized patients. In such situations number of preferred antibiotics was limited. The aim of this study was to investigate in-vitro susceptibility of fusidic acid to clinic isolates of Staphylococci.Materials and methods: The seventy-seven coagulase negative staphylococci (CNS) and 37 Staphylococcus aureus strains isolated from various clinical specimens were included in this study.Staphylococci were identified with gram stain, catalase and coagulase tests. According to “Clinical and Laboratory StandardsInstitute (CLSI)” criteria, antimicrobial susceptibility testing was performed by Kirby-Bauer disc diffusion method.Results: The seventy-four percent of the isolated CNS were defined as methicillin sensitive-CNS (MS-CNS), 26% of the isolated CNS were defined as methicillin resistant (MR-CNS). While 40% of MR-CNS was resistant to fusidic acid, fusidic acid resistance was found to be 24% in MS-CNS.In methicilline-sensitive S.aureus strains fusidic acid resistance rate were detected as 13%; and in methicillin-resistant S.aureus strains the rate were 14%.Conclusion: Susceptibility of fusidic acid in Staphylococcus aureus strains were found higher than coagulase-negative staphylococci. Fusidic acid remains as an alternative in the treatment of infections due to staphylococci. J Microbiol Infect Dis 2011;1(1):22-25.

Abstract: Today, remote sensing is used for different methods and different purposes. In all of the detection methods, some considerations such as low energy consumption, low cost, insensitivity to environmental changes, high accuracy, high reliability and robustness become important. Taking into account these facts, remote sensing methods are used in applications such as geological and archeological research, engineering areas, health services, preserving and controlling natural life, determination of underground sources, controlling air, sea and road traffic, military applications, etc. The method to be used is based on the object type to be detected, material to be made, and location to be found. The remote sensing methods from the past up to today can be listed as acoustic and seismic, ground penetration radar (GPR) detection, electromagnetic induction, infrared (IR) imaging, neutron quadrupole resonance (NQR), thermal neutron activation (TNA), neutron back scattering, X-ray back scattering, and magnetic anomaly detection. In these methods, detected raw images have to be processed, filtered and enhanced. In order to achieve these operations, some algorithms are needed to be developed. In this study, the methods used in detecting land mines remotely and their performance analysis have been given. In this way, the last situation on the advantages and disadvantages of methods used, application areas and detection accuracies are determined. Furthermore, the algorithms such as transmission line matrix (TLM), finite difference time-domain (FDTD), the method of moment (MoM), split step parabolic equation (SSPE) and image processing and intelligent algorithms are presented in detail.

Abstract: In order to estimate the speed of a moving vehicle with side view camera images, velocity vectors of a sufficient number of reference points identified on the vehicle must be found using frame images. This procedure involves two main steps. In the first step, a sufficient number of points from the vehicle is selected, and these points must be accurately tracked on at least two successive video frames. In the second step, by using the displacement vectors of the tracked points and passed time, the velocity vectors of those points are computed. Computed velocity vectors are defined in the video image coordinate system and displacement vectors are measured by the means of pixel units. Then the magnitudes of the computed vectors in image space should be transformed to the object space to find the absolute values of these magnitudes. This transformation requires an image to object space information in a mathematical sense that is achieved by means of the calibration and orientation parameters of the video frame images. This paper presents proposed solutions for the problems of using side view camera images mentioned here.
