Evaluation of the analgesic efficacies of Dexketoprofen Trometamol and Dexketoprofen Trometamol + Thiocolchicoside combinations in the impacted third molar surgery : Randomised clinical trial

Postoperative pain is one of the most common complications. The aim of this study is to evaluate the analgesic efficacies of dexketoprofen trometamol and two different dosages of dexketoprofen trometamol + thiocolchicoside combination in the impacted third molar tooth operation. This randomized, double-blind study included 75 patients who did not have any disease. Patients were assigned to 3 groups. Group 1 received 25 mg dexketoprofen trometamol + 4 mg thiocholchicoside, Group 2 received 25 mg dexketoprofen trometamol +8 mg thiocholchicoside, and Group 3 received 25 mg dexketoprofen trometamol. In each group, the analgesic medication was administered twice a day, starting 1 hour before the operation. The level of pain was assessed with VAS. Patient age varied from 18 to 36 years. Of all patients, 59.2% (n=42) were female and 40.8% (n=29) were male. Drug side effects were observed in 28.17% (n=20) of the patients. Mean 24th hour VAS score was lower in dexketoprofen trometamol + 8 mg thiocolchicoside group compared to dexketoprofen trometamol group (p0.05). Dexketoprofen trometamol + 8 mg thiocolchicoside combination has higher analgesic efficacy compared to dexketoprofen trometamol. More studies are needed to interpret the analgesic and anti-inflammatory effects of thiocholchicoside + dexketoprofen trometamol combination

The relationship between frontal sinus dimensions and skeletal malocclusion

PurposeThe aim of this retrospective research is to compare frontal sinus dimensions in skeletal Class I, skeletal Class II, and skeletal Class III individuals and to evaluate the relationship of these dimensions with anterior skull base length and some cephalometric values.Materials and MethodsIn this research, we used lateral cephalometric radiographs of 60 people aged 17 to 25. In individuals with skeletal Class I malocclusion, skeletal Class II malocclusion due to mandibular insufficiency, and skeletal Class III malocclusion due to mandibular excess, measurements of frontal sinus length and height as well as S-N, Co-A and Co-Gn lengths, ANB0, FMA0, SN-GoGn0 angles values were performed. The length between the highest point and the lowest point of the frontal sinus was calculated as the height of the frontal sinus, and the length between the most anterior and the most posterior points of the frontal sinus was calculated as the length of the frontal sinus.ResultsThe frontal sinus length and height were found to be higher in skeletal Class III individuals than in skeletal Class I and skeletal Class II individuals, however, there was no significant difference between skeletal Class I and Class II individuals.ConclusionThe increase in frontal sinus height and length correlated positively with the decrease in the ANB angle and the increase in the SN and Co-Gn lengths. The dimensions of the frontal sinus may be an indicator for the remaining mandibular growth potential

Acoustic sensor network design for position estimation

In this paper, we develop tractable mathematical models and approximate solution algorithms for a class of integer optimization problems with probabilistic and deterministic constraints, with applications to the design of distributed sensor networks that have limited connectivity. For a given deployment region size, we calculate the Pareto frontier of the sensor network utility at the desired probabilities for d-connectivity and k-coverage. As a result of our analysis, we determine (i) the number of sensors of different types to deploy from a sensor pool, which offers a cost vs. performance trade-off for each type of sensor, (ii) the minimum required radio transmission ranges of the sensors to ensure connectivity, and (iii) the lifetime of the sensor network. For generality, we consider randomly deployed sensor networks and formulate constrained optimization techniques in a Bayesian experimental design framework to obtain the best point estimates of a given state-of-nature, represented by a finite number of parameters. The approach is guided and validated using an unattended acoustic sensor network design. Finally, approximations of the complete statistical characterization of the acoustic sensor networks are given, which enable average network performance predictions of any combination of acoustic sensors

Design considerations for a heterogeneous network of bearings-only sensors using sensor management

This paper presents a design characterization of heterogeneous sensor networks with the goal of geolocation accuracy. It is assumed that the network exploits sensor management to conserve node power usage. We focus on bearings-only sensor networks consisting of acoustic and imaging modalities. Each available node modality is a bearings-only sensor of varying capability. The optimal mixture of modalities is discussed under the constraint of the overall network cost. Finally, simulations verify the theory and demonstrate design choices

Comparison of Various Measurement Methods in the Evaluation of Swelling After Third Molar Surgery

Objective: This study aimed to examine the differences between 12 metric swelling evaluation methods in patients undergoing impacted lower third molar surgery. Material ve Methods: This study was conducted on the patients indicated for the extraction of impacted lower third molar teeth due to orthodontic reasons. Twenty-six patients aged between 18-40 were included in the study. Swelling levels after surgery were measured using anatomic landmarks used for the methods, and the distances between landmarks were measured before the operation, and on days 2 and 7 afterward. The measurements were done using thread and a millimeter ruler while patients were seated. The distances between the anatomical landmarks were evaluated by 12 different methods. Results: According to the results of the measurements performed on twenty-six patients, (15 male and 11 female) with a mean age of 23.85±6.06 years, male had more swelling than female and the difference was statistically significant (p0.05). Conclusion: As a result of the present study; twelve swelling evaluation methods showed significantly similar results and the authors recommended using Method 1 and 5 for convenient clinical evaluation which could be performed with a smaller number of anatomical points

SİC takviyeli̇ alüminyum matrisli kompozit malzemenin farklı kaynak akımları ve türlerinde oluşan mi̇kroyapi ve sertlik özelliklerinin analizi

The welding of metal matrix material reinforced with ceramic particles has some problems such as formation of oxide layer, segregation occurring on welding area, and reaction of ceramic particles with welding bath. The expected mechanical properties cannot be obtained because of these problems. In this study, the weldability of aluminum 2014 alloy reinforced with SiC particles was investigated. MIG welding process was used via using AlSi5 alloy wire at different types and values of welding currents. Samples obtained using manual welding current were compared to those obtained using pulse welding current, in terms of microstructure and distribution of hardness. The effects of different types and values of welding currents on the microstructure and hardness distribution were examined. It was obtained that the welding of the composite with aluminum 2014 alloy matrix reinforced with SiC particles via using of pulse current, potential formation of segregation was prevented and microstructural properties were improved

Evaluation of dental anxiety in patients undergoing second-stage surgery with er, cr: YSGG laser treatment: Randomized clinical trial

Oral surgical procedures cause high-pain expectation and consequent anxiety in patients. The aim of this study is to compare the effects of Er, Cr: YSGG laser and scalpel method on dental anxiety level during second-stage implant surgery. 96 patients with 304 osseointegrated implants were divided into two groups. Implants embedded under the oral mucosa were exposed with scalpel or laser surgery. Before the operation the patients were asked to fill the STAI and DAS while resting in the waiting room. In addition, postoperative daily analgesic use, VAS scores perioperativly and on the postoperative 1st, 2nd and 3rd days and demographic information such as age and gender were also recorded. There was no statistically significant relationship between surgical method and anxiety levels (p>0.05. Also, the differences between the scalpel and laser groups in terms of total DAS and STAI scores were statistically insignificant (p>0.05). But statistically significant difference was found between surgical method and the analgesic consumption (p<0.05). A higher rate of analgesic consumption was observed in the scalpel group. The use of Er,Cr;YSGG laser could reduce pain during minor oral surgical procedures but had no significant effect on dental anxiety. Different modalities that could provide additional benefits in overcoming this situation should be investigated. © 2020, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved

The Evolution of KTP Laser Vaporization of the Prostate

The search for a minimally invasive approach to the treatment of Lower Urinary Tract Symptoms (LUTS) suggestive of Benign Prostatic Hyperplasia (BPH) is probably as old as Transurethral Resection of the Prostate (TURP). In an effort to overcome the limitations and morbidities of TURP, and in light of evidence suggesting that medical treatment for BPH has a limited life-span, laser-based treatments have emerged during the last decade. Photoselective Vaporization of the Prostate (PVP) by the "GreenLight" KTP laser is considered one of the most promising options, one that is constantly evolving new technologies in prostate surgery. In this overview of KTP laser usage in BPH treatment, we will briefly discuss the evolution of this modality since it was first introduced and focus on the available evidence regarding safety, efficacy and cost parameters of its application

Suicide risk in schizophrenia: learning from the past to change the future

Suicide is a major cause of death among patients with schizophrenia. Research indicates that at least 5–13% of schizophrenic patients die by suicide, and it is likely that the higher end of range is the most accurate estimate. There is almost total agreement that the schizophrenic patient who is more likely to commit suicide is young, male, white and never married, with good premorbid function, post-psychotic depression and a history of substance abuse and suicide attempts. Hopelessness, social isolation, hospitalization, deteriorating health after a high level of premorbid functioning, recent loss or rejection, limited external support, and family stress or instability are risk factors for suicide in patients with schizophrenia. Suicidal schizophrenics usually fear further mental deterioration, and they experience either excessive treatment dependence or loss of faith in treatment. Awareness of illness has been reported as a major issue among suicidal schizophrenic patients, yet some researchers argue that insight into the illness does not increase suicide risk. Protective factors play also an important role in assessing suicide risk and should also be carefully evaluated. The neurobiological perspective offers a new approach for understanding self-destructive behavior among patients with schizophrenia and may improve the accuracy of screening schizophrenics for suicide. Although, there is general consensus on the risk factors, accurate knowledge as well as early recognition of patients at risk is still lacking in everyday clinical practice. Better knowledge may help clinicians and caretakers to implement preventive measures. This review paper is the results of a joint effort between researchers in the field of suicide in schizophrenia. Each expert provided a brief essay on one specific aspect of the problem. This is the first attempt to present a consensus report as well as the development of a set of guidelines for reducing suicide risk among schizophenia patients

Wykrywanie naprężenia osnowy za pomocą teledetekcji podczas wytwarzania tkanin o splotach skośnym i satynowym

Warp tensions were measured while a machine was operating on a woven cotton fabric with three different woven patterns. This study was carried out with image analysis methods using a high speed camera. Three weave pattern types: plain, twill and satin were woven on the same weaving machine, and thus it could be understood how weave pattern differences affect warp tension. Each of these three weaves was woven in three weft densities: 20, 28 and 45 wefts per cm. These fabrics were able to be made on a weaving machine with an automatic dobby. It was aimed to investigate warp tension differences for three basic weave patterns while keeping all machine settings constant. The weave settings of the dobby were changed for plain, twill and satin weaves. Warp tension calculation was based on the warp elasticity theory. Warp elasticises were measured by image processing methods in MATLAB using a high-speed camera. It was aimed to improve upon the new method of warp extension measurement of fabric when the loom is in operation. It was observed that the warp tension in plain fabric was higher than for twill and satin under the same conditions.W pracy mierzono naprężenia osnowy podczas wytwarzania tkanin bawełnianych o trzech różnych wzorach. Badanie zostało przeprowadzone metodami analizy obrazu przy użyciu kamery. Na tej samej maszynie tkano trzy rodzaje wzorów splotu: gładki, diagonalny i satynowy, dzięki czemu zbadano wpływ rodzaju splotu na napięcie osnowy. Każdy z tych trzech splotów został utkany w trzech gęstościach wątku: 20, 28 i 45 wątków/cm. Celem pracy było zbadanie różnic naprężeń osnowy dla trzech podstawowych wzorów splotów, przy jednoczesnym zachowaniu stałych ustawień maszyny. Obliczenia naprężenia osnowy oparto na teorii sprężystości osnowy. Elastyczność osnowy mierzono metodami przetwarzania obrazu w programie MATLAB przy użyciu kamery. Celem badania było ulepszenie nowej metody pomiaru wydłużenia osnowy tkaniny podczas pracy krosna. Zaobserwowano, że naprężenie osnowy w tkaninie gładkiej było wyższe niż w przypadku diagonalu i satyny w tych samych warunkach
