Aim: Objective of this study was to investigate the endoplasmic reticulum (ER) stress and apoptosis mediated anticancer ef fect of boric acid in human pancreatic cancer MIA PaCa-2 and P ANC-1 cells. Materials and Methods: The effect of boric acid on the viability of pancreatic cancer cells and the IC50 value were calculated by XTT test and using CompuSyn version 1.0 software. Apoptotic, anti-apoptotic and ER stress-related gene levels were determined. The effect of boric acid on the colony formation capacity of these cells was evaluated with the colony formation assay.
Results: Boric acid inhibited cell viability in these cell lines as time and dose dependent. As a result of the XTT test, the IC50 doses of boric acid in MIA PaCa-2 and PANC-1 cells were found to be 15707.5 and 14248.8 μM, respectively. Boric acid significantly upregulated BAX, CASP3, CASP8, CYCS and FAS expression, which are the genes associated with apoptosis in both cell lines. CASP9 and FADD gene levels were significantly elevated only in PANC-1 cells. It was observed that boric acid statistically upregulated the expression of ATF4, HSP47 and XBP1 genes associated with ER stress in both cell lines. In addition, boric acid treatment significantly increased ATF6, CHOP and EIF2A expressions only in PANC-1 cells. Boric acid also caused an increase in GRP78 gene expression in MIA PaCa-2 cells. Colony formation test results illustrated that boric acid significantly suppressed co lony formation capacities in both cell lines.
Conclusion: Boric acid reduced cell viability and colony formation in both human pancreatic cancer cells and changed gene levels in apoptosis and ER stress pathways. Findings suggested that boric acid exhibits anticancer activity in human pancreatic cancer cells v ia ER stress and apoptosis.

Aim: Thyroid Hormone Receptor Interacting Protein 13 (TRIP13) is a protein involved in spindle-aggregation checkpoint, which plays a role in meiotic recombination. Recent studies have revealed that TRIP13 may be a potential tumor inducer in many cancers, including glioblastoma multiforme (GBM). We aimed to investigate the anticancer activity of DCZ0415, a small molecule inhibitor of TRIP13, in U87 human GBM cells in this study.

Materials and Methods: The possible anticancer effect of DCZ0415 on U87 cells was determined by cytotoxicity, colony formation, and apoptosis assays. In addition, the effects of DCZ0415 on mRNA levels of genes which were involved in apoptosis, invasion and Transforming Growth Factor-Beta (TGF-β) signaling pathway were investigated by qRT-PCR analysis.

Results: DCZ0415 inhibited U87 cell proliferation in a dose and time dependent manner. The IC₅₀ dose of DCZ0415 for 48 hours was determined as 19.77 µM in U87 cells. DCZ0415 treatment at this dose induced apoptosis and suppressed colony forming abilities of U87 cells. In addition, DCZ0415 altered mRNA levels of genes associated with apoptosis, invasion and TGF-β signaling pathway, which could lead to anticancer effects.

Conclusion: DCZ0415, an inhibitor of TRIP13 which has been evaluated as a new oncogenic factor in cancer, has an anticancer effect on GBM cells. In this respect, it is thought that TRIP13 may be an important therapeutic target for GBM and DCZ0415 may be considered as an effective inhibitor that causes anticancer effects in GBM cells.

Aim: It was aimed to investigate  the relationship of disease clinical stage between the maximum diameter of primer lesion (LEGÇ), maximum of standardized uptake value (SUVmax), mean of standardized uptake value (SUVmean), tumor volüme (TV) and total lesion glycolysis (TLG) values derived from positron emission tomography/computed tomography (PET/CT) images.

Method: The information of 130 lung cancer patients diagnosed histopathologically between 01.01.2012 and 31.12.2014 in Necmettin Erbakan University Nuclear Medicine Department of Meram Medical Faculty scanned for PET-CT for lung cancer diagnosis and staging,  were included in this study. The values of the maximum diameter of primer lesion, SUVmax, SUVmean, TLG and MTV derived from PET-CT scanning and their histopathological subtypes, other clinical and radyological information of patients were noted. The non-small cell lung cancer patients were graded according to tumor diameter, nodal and involvement metastasis (TNM) staging system using clinical information, PET-CT and other radyological test results if any. On the other hand, the small cell carcinoma diagnosed were categorised as limited or extensive stage.

Findings: In this study, the mean age of 118 men and 12 women,  totally 130 patients, was evaluated  63,46 ±9,96 ( range 40-87 age ). The patients were classified as 106 non-small cell lung Cancer (NSCLC) (81.5%) ve 24 small cell lung cancer (SCLC) (18.5%).  The  histopathologically diagnosed NSCLC patients were consists of  62 squamous cell cancers, 39 adeno cancers, and 5  other types (3 carcinoid tumors, 1 large cell cancer and 1 sarcomatoid tumor). 

Results: In our study, it was observed that there was no significant relationship between the maximum diameter of the lesion, SUVmax, SUVmean, MTV and TLG values among SCLC and NSCLC patients. Additionally, it was also found that there was no correlation between these parameters and the SCLC stage.  The maximum diameter of the lesion, SUVmax, SUVmean, MTV and TLG parameters were related with stage.

Conclusion: Higher SUVmax, SUVmean, TV, and TLG values of the primary tumor were determined to predict the more advanced clinical stage in NSCLC. This relationship between metabolic parameters and the clinical stage suggest that PET / CT may be valuable in terms of providing prognostic information in NSCLC.

Objective: The aim was to review the hormonal status, treatment and histopathological diagnosis of patients admitted to our endocrinology outpatient clinic with the diagnosis of adrenal incidentaloma.

Material and Methods:Between 2015-2018, 217 patients with adrenal incidentaloma who were admitted to the endocrinology outpatient clinic were included in the study. 1 mg overnight dexamethasone suppression test (DST), 24 hour urine free cortisol, 24-hour urine methanephrine and normetanephrine levels were evaluated in all patients.Patients who also have hypertension or hypokalemiawere screened for the plasma aldosterone/renin activity ratio. CT or MRI imaging properties of adrenal incidentalomas were screened.

Results: In the evaluation of cases; 180 (83%) of the masses were evaluated as non-functional and 37 (17%) as functional. Of the 37 patients evaluated as having functional adrenal mass; 10 (4.6%) pheochromocytoma, 5 (2.3%) Cushing's syndrome, 9 (4.1%) subclinical Cushing’s syndrome and 13 (6%) primary hyperaldesteronism were detected. In 180 patients who were evaluated as having non-functional adrenal mass; metastatic disease in 7 (3 non-small cell lung cancer, 1 breast cancer, 1 prostate carcinoma and 2 unknown primary cancer), myelolipoma in 4, ganglioneuroma in 1, hydatid cyst in 1, adrenocortical carcinoma in 2 patients were detected.

Conclusion: According to the results of this study, it is not uncommon for adrenal incidentalomas to be functional. It may be malignant in some cases. For this reason, adrenal incidentaloma is a condition that should be examined both in terms of
functionality and malignancy potential.

ABSTRACT

Aim: Avascular necrosis of the femoral head (AVN) is the necrosis of the bone and the bone marrow resulting from the injury or the occlusion of the blood supplying vessels of the femoral head. Specially it is seen in mostly young and middle aged individuals and requiring mostly surgical procedures. Despite all advances in the surgical procedures, still a high rate of the hip prosthesis is a requirement in the treatment. Hyperbaric Oxygen Therapy (HBOT) alone or in combination with surgery is reported to be effective in some clinical AVN cases. HBOT is also a treatment method which is used in ischemic diseases resulting from vascular injuries or occlusions. Enoxaparin is an antagonist of factor Xa which is found in the coagulation system. Beside its anticoagulant effect it has been shown that it has an osteopenic effect, inhibits osteoblast maturation and increases osteoclast activity in the bone.

Material and Methods: In this study effects of enoxaparin and HBOT were investigated in the treatment of experimentally formed AVN of the femoral heads of the rats. For this purpose, avascular necrosis model was applied to the left femoral heads of 64 rats and the results of the treatments alone and together were investigated.

Results: In this study results have shown that an increase in the new bone formation, and remodelisation with less changes in the cartilage tissue than in the controls. An increase in the necrotic tissue clearing rate observed in the HBOT applied groups. The best results were achieved with the HBOT and enoxaparin combined applications.

Conclusion: In this study HBOT alone, enoxaparin alone or combination of these two treatments have a positive effect in the experimental femoral head AVN and supporting the clinical studies in the femoral head AVN.

Keywords: Hyperbaric oxygen therapy, avascular necrosis, enoxaparin

Aim: The aim of this study was to evaluate the interobserver and intraobserver reliability of quantitative
corneal subbasal nerve plexus (CSNP) analyses using semi-automa ted software.
Patients and Methods: Forty volunteers who applied to the Ophthalmology Department of the Necmettin
Erbakan University Meram Medical Faculty between 20 December 2021 and 20 January 2022 were
enrolled in the study. Images showing CSNP were obtained from the right eyes of the participants by using
Heidelberg Retina Tomograph III with Rostock Cornea Module. Three best quality images were selected
from each case. NeuronJ plugin for ImageJ software was used to trace nerve fibers and calculate nerve
fiber length (NFL), nerve fiber density (NFD), and nerve branch density (NBD). All these measurements
were performed by two different observers, and repeated for the second time by one of the observers
with an interval of one week, and interobserver and intraobserver reliability were determined using the
intraclass correlation coef ficient (ICC).
Results: The mean age of 40 participants (12 female and 28 male) was 34.70±5.86 years. The ICCs
for interobserver reproducibility were 0.967 (95% CI 0.939-0.982) for NFL, 0.826 (95% CI 0.696-0.904)
for NFD, and 0.949 (95% CI 0.906-0.973) for NBD indicating good to excellent reliability. The ICCs for
intraobserver repeatibility were 0.964 (95% CI 0.932-0.981) for NFL, 0.803 (95% CI 0.657-0.891) for NFD,
and 0.890 (95% CI 0.802-0.941) for NBD indicating good to excel lent reliability.
Conclusion: Quantitative CSNP analyzes using semi-automated software have high interobserver and
intraobserver reliability and can therefore be used in both clinical practice and clinical studies for detection
and follow-up of corneal nerves’ well-being, damage, and evaluation of response to treatment.

Aim

This study aims to determine the prevalence of falls and associated risk factors among elderly living in Sinop, Turkey.

Materials and methods

The universe of this cross-sectional study consists of 32506 people older than 65 years old whom are registered to the family physicians’ information system and live in Sinop. After stratification for sex and age (65-74, 75 and over) a sample size of 2463 and 92.1% were reached. Data about some of the socio-demographic characteristics, falling status, daily living activity functionalities, depression status and awareness about falls of the participants were collected via a structuralized questionnaire. Relations between falls and associated risk factors were assessed by four different logistic regression models.

Results

The mean of falling prevalence after age 65 among elderly was 36.4%. Not being graduated from any school, having low scores for current health conditions, using more than one drug daily, not being able to walk without support and being positive for depression are found to be risk factors for falling among both sex and age groups. Having a chronic disease, living alone, having fear of falling, having low awareness about falls, being dependent in daily living activities and having inadequate knowledge about prevention from falls are found to be risk factors for at least two of the sex and age groups. There were no statistically significant relations between falling risk and previous or current employment status.

Conclusion

Falls are important public health concerns among elderly and the variability of risk factors depending on determinants such as age and sex should be considered while planning further implementations targeting fall prevention and control of risk factors for elderly.

Objective: Most of the renal neoplasms are the epithelial and malign ones. The renal cell carcinoma (RCC), which is the most frequently seen malign renal tumor, consists of 2-4% of all the malign tumors seen among adult individuals and 80-90% of all the malign renal tumors. RCCs peak at sixties and seventies and its prevalence among males is two folds of its prevalence among females. RCCs have bad prognosis. The recurrence is seen in 40% of the cases, and the metastasis despite the early diagnosis was detected in 50% of cases. In present study, it was aimed to distribution of renal tumors in our hospital, discuss the prognostic factors such as the, pathological stage, nuclear grade and tumor diameter accompanied by literature information.

Patients and Method: By retrospectively scanning the records of Pathology Department of Medical Faculty, Fırat University, for the period between 1988 and 2009, 140 renal tumor cases were determined and the previous diagnoses, histological degrees, pathological stages of these cases were evaluated and the final diagnoses were taken as base in the present study. In pathologically staging (pT) of RCCs, TNM classification was used, whereas Fuhrman nuclear grading (FNG) was used in nuclear grading procedure. The patients were divided into different groups based on their genders and ages. The statistical analyses were performed in SPSS-12.0 software by using Chi-Square and Correlation tests.

Results: When compared to the literature in terms of the mean age, the present study involves relatively young population (mean age 57), and the majority was male (male/ female:1.1). The distributions of renal tumours, malign and benign subtypes, and RCC subtypes show similarities with the general literature. When examining the RCCs statistically, no significant relationship was found between diagnosis and age, and between nuclear grade and tumor diameter (p>0.05). In the present study, the RCCs with largest diameter were papillary type (9,78cm) ones, whereas the RCCs with lowest diameter values were classic type. A statistically significant relationship was observed between the benign, borderline and malign tumor diagnoses and diameters (p= 0.023). It was determined that approximately one-four of RCC cases were in highly pathological stage (21,6%, pT3a-3b). A direct proportional and statistically significant relationship was found between nuclear grade and diameter (p=0,002).

Conclusion: RCCs have poor prognosis and their frequency is increasing. Pathological stage, nuclear grade and diameter are the leading factors affecting the prognosis. As in our study, in retrospective studies involving old ages and not enough sampling, tumor diameter may be used as an alternative prognostic factor for pathological staging in tumors with a stage above pT2.

Aim: The prolonged process of new coronavirus disease (COVID-19) and related restrictions cause
physical inactivity, fear of COVID-19, and fatigue in individuals. During the pandemic, kinesiophobia may
raise fear of death and physical inactivity in patients. However, kinesiophobia and its relationship with
physical activity (PA), fear of COVID-19, and fatigue in individuals have not been known yet, which was
therefore aimed to investigate in the current study .
Patients and Methods: Adult individuals (n=166, 36.3±15.37 years) were included in the study.
Kinesiophobia (Tampa Scale of Kinesiophobia), PA levels (International Physical Activity Questionnaire-
Short Form), fear of COVID-19 (Fear of COVID-19 Scale (FCS-19)), and fatigue (Numeric Rating Scale)
were evaluated remotely between 3 June 2021 and 30 June 2021 th rough an online platform.
Results: Of the individuals, 91 (54.8%) had a high level of kinesiophobia, 55 (33.1%) were inactive, 84
(50.6%) were minimally active, and 27 (16.3%) were very active. Kinesiophobia score was significantly
correlated with age, weight, body mass index, education level, and walking, total PA, FCS-19, and fatigue
scores (p<0.05).
Conclusion: Kinesiophobia and physical inactivity are prevalent in many individuals. Although individuals
have no disease during the COVID-19 pandemic, their kinesiophobia level increases as walking, physical
activities, and education levels decrease. Kinesiophobia also increases as age, weight, body mass
index, fear of COVID-19 and fatigue increase. Considering the negative effects of kinesiophobia and the
prolonged pandemic process, individuals should be urgently dire cted to P A counseling programs.

Introduction: Our aim is to evaluate the cardiac involvement of Neurofibromatosis type 1  patients in our region and to compare them with other clinical findings. In this study, we wanted to show the frequency and variety of cardiac involvement.

Material and Methods: Patients diagnosed with Neurofibromatosis type 1  in Hatay Mustafa Kemal University Medical Faculty Pediatric Neurology Clinic between 01/09/2019 and 01/09/2020 were included in the study. The patients included in the study were examined by a Pediatric Cardiology Specialist, and echocardiography and electrocardiography were taken. Demographic information, examination findings, brain magnetic resonance images were collected from the files of the patients. Electrocardiography and echocardiography were examined and recorded by the Pediatric Cardiology Specialist.

Results: We accepted 17 patients from our center to the study. Six patients (35.3%) were diagnosed with sporadic Neurofibromatosis type 1, while 11 patients (64.7%) had familial Neurofibromatosis type 1. All of our patients had cafe au late spots on the skin. In addition, 10 (58.8%) patients also had axillary and / or inguinal freckles. We detected optic glioma in 3 of our patients with ocular involvement, and lish nodules in 3 of them with papillary edema. When we looked at central nervous system involvement, we encountered various involvements in brain MRIs of 8 (47%) patients. In our cardiac examination, we found QT length in 1 patient’s electrocardiography. In the echocardiography we performed for the detection of cardiac structural pathologies, we detected nodular appearance compatible with subendocardial neurofibroma in 3 patients, mitral insufficiency in 3 patients, patent foramen ovale in 1 patient, atrial septal defect in 1 patient, and bicuspid aorta in 1 patient.

Discussion: In our study, unlike the literature, subendocardial nodular hyperechogenic appearance was present in 3 patients. Although these findings are quite rare, subendocardial nodular hyperechogenic images in 3 of our 17 patients suggest that this pathology may be more common. In addition, one of our patients had a long QT. As far as we know, this is the first case of Neurofibromatosis type 1 and Long QT syndrome. In conclussion; Cardiac involvement in patients with Neurofibromatosis type 1 could more common than mentioned in the literature.

Since the identification of SARS-CoV-2, a multisystem inflammatory syndrome (MIS-C) that appears in
children after COVID-19 disease and mimics Kawasaki disease was reported in the UK in April 2020,
while it is associated with Covid-19 in adults. Multisystem inflammatory syndrome (MIS-A) was reported
in June 2020. MIS-A patients have been reported to be up to 50 years of age in the literature and are more
likely to have some underlying health condition and have recently had an identifiable respiratory disease
compared to MIS-C. On the other hand, MIS-A patients and MIS-C patients have many overlapping clinical
features, but the severity of cardiac dysfunction, incidence of thrombosis, and MIS-A mortality may be
higher in MIS-A. While it is clear that neutrophilia, lymphopenia, and thrombocytopenia are common in
MIS-C/A, these features, together with elevations in troponin and BNP/NT-proBNP, have been considered
measures of disease activity .

Aim: Many scales have developed to assess daily living activities, clinical functions of patients with brachial plexus palsy. "Brachial Plexus Outcome Measure " was developed by Emily Ho in 2012, activity and self-rating substance scale consisting of components total 14 items. Aim of this study, make an inter-observer reliability of scale, to make clinical trial in patients.

Materials and Methods:Demographic and clinic datas recorded,"Brachial Plexus Outcome Measure " was applied by two different observers. Inter-observer reliability in items examined by using kappa statistic.

Results:Eighteen female (37.5%) totally 48 patients included. Mean inter-observer agreement in the items was almost perfect (kappa 0.93) in raters. Fitted statistics showed much variation in observers had moderate (kappa 0.57) agreement in items.

Conclusion: Between observes, “Brachial Plexus Outcome Measure” is reliable measurement for assessing functions in children with brachial plexus palsy in Turkey. Clinical usage is appropriate.

\r\n Prognostic importance of thrombocyte indices in children with carbon monoxide poisoning

\r\n

\r\n Abstract

\r\n

\r\n Objective: Carbon monoxide (CO) poisoning is still being a major cause of morbidity and mortality all over the world. Although the role of platelet functions in CO poisoning is not clear, increased platelet activation and aggregation had been reported previously. Increased thrombotic tendency due to endothelial damage, increased platelet stickiness, and alterations in the fibrinolytic pathway occurs in CO poisoning. The aim of our study was to determine whether platelet indices provide clinical benefit or not in children with CO poisoning.

\r\n

\r\n Materials and Methods: We retrospectively reviwed the records of children with the diagnosis of CO poisoning who admitted to the pediatric emergency departments of Konya Beyhekim State Hospital and Necmettin Erbakan University Meram Medical Faculty. A total of 92 children with CO poisoning and 62 age- and gender-matched healthy controls were included in the study.

\r\n

\r\n Results: While mean platelet volume (MPV) and platelet distribution width (PDW) levels were significantly higher (9,34±0,55 vs 9,78±0,97fL, p=0.001 ; 11,46±2,64 vs 10,57±1,41, retrospectively, p=0.007), platelet count and plateletcrit (PCT) (324,05±82,07 vs 357,27±89,70 x10⁹ p=0.015 ; 0,31±0,06 vs 0,33±0,07, retrospectively, p=0.039) were significantly lower in patients with CO poisoning. MPV levels were also significantly higher in patients with a carboxy hemoglobin (COHb) level higher than 20, when compared with COHb levels between 10-20 (9,40±0,84 vs 10,08±1,22 fL, p=0.003).

\r\n

\r\n Conclusion: Our results showed that platelet indices MPV and PDW are markedly elevated in patients with CO poisoning while platelet count and PCT were decreased. MPV and PDW levels, which reflect the changes in platelet activation and function, may predict the development of especially thromboembolic complications in the course of CO poisoning.  MPV and PDW levels may be useful in prognostic estimation of CO poisoning.

Aim: The aim of this study was to primarily investigate the effects of selected anesthesia method on anxiety, patient satisfaction and pain level in elective caesarean section, and secondarily obtain information about quality of service.

Materials and Methods: The study was carried out as a prospective questionnaire in the Department of Anaesthesiology and Reanimation the Meram Medical Faculty Hospital of Necmettin Erbakan University between June 2017 and August 2017, on 160 volunteers aged between 18 and 45 years for whom elective cesarean section under General Anesthesia (GA) or Spinal Anesthesia (SA) was planned. Demographic data of the patients such as age, place of residence, education level, number of children, and cesarean experiences were recorded. In the preoperative and postoperative period, anxiety levels were measured by State-Trait Anxiety Inventory (STAI-D), pain levels were measured by Visual Analog Scale (VAS) scores and satisfaction levels were evaluated at postoperative 6th and 24th hours by (Quality of Recovery: QoR 40 T) questionnaire.

Results: There was no statistically significant difference between the patients' preoperative and postoperative anxiety scores and demographic data (p> 0.05). Patients with previous cesarean experience had lower preoperative anxiety levels (p <0.05). The STAI-D scores and the numbers of patients with anxiety in the GA and SA groups were similar (p> 0.05).Postoperative anxiety levels were significantly lower in both groups than in the preoperative period (p <0.05). VAS values of the SA group at the 6th and 24th hours were significantly higher than the group treated with GA.(p<0.05). The 24th hour VAS values of the SA group were higher than the VAS values at the 6th hour (p <0.05). In the GA group, VAS values at 24th hour were lower than the VAS values at 6th hour (p <0.05). The satisfaction levels of general anesthesia and spinal anesthesia were similar in the postoperative period (p> 0.05). Complaint of headache was high in SA group while complaint of sore throat was high in GA group(p<0.05). While there was no correlation between anxiety level, VAS values and satisfaction level (p> 0.05), there was a negative correlation between VAS values and pain parameters, which are the subgroup of satisfaction questionnaire, in both groups (p <0.05).

Conclusion: It is concluded that the preferred anesthesia method in elective cesarean section has no effect on anxiety and satisfaction, and the patient satisfaction level and service quality will be improved by providing effective analgesia by reviewing our postoperative pain algorithm.

Aim: This study evaluated the antibacterial effect of gaseous ozone on multi-drug resistant (MDR)
pathogens with regard to time dependency. Controlling infections with MDR bacteria became a big
challenge for health care professionals. Therefore, the major corcern should be altered to alternative
therapies.
Materials and Methods: The study was performed in Necmettin Erbakan University Meram Medical
Faculty Hospital, Department of Medical Microbiology Laboratory between 21 March to 15 April 2021. Ten
MDR bacteria were evaluated in vitro using in the Petri dishes at seven bacterial concentrations (102-
108 bacteria/dish). The ozone showed its efficacy on these MDR bacteria under the following conditions
applied: 40 μg/ml at 10, 20 and 40 minutes and control (no gas was used). After 24 hours incubation of
plates, the average colony counts for each exposure time of ozone were figured out and transformed to
Log10.
Results: Taking acccount the mean bacterial reduction (log10), the bactericidal effect of ozone was
determined on only methicillin-resistant Staphylococcus aureus, VIM-1 producing Klebsiella pneumoniae
and Carbapenem resistant-Acinetobacter baumannii in 10 minutes exposure. The optimum effect was
generally observed within 20 minutes on tested isolates. However, the MDR-Pseudomonas aeruginosa
showed a relatively lower response to ozone. All bacteria was inactivated over the level at 99% at the end
of the 40 min exposure to ozone.
Conclusions: The gaseous ozone showed satisfactory bactericidal activity on MDR pathogens and its
effect depens on exposure time and type of bacteria. Taken into account, the need for new approaches
for the control of microbial infections in the pandemic world, the optimization of ozone therapy should be
undertaken high priority and more in vivo studies are needed to support in depth understanding of the
ozone ef fect on the inactivation of MDR bacteria.

 Today an increasing prevalence of obesity, which is one of major health problems is associated with many chronic diseases such as diabetes, cardiovascular disease, stroke, cancer, asthma obstructive sleep apnea syndrome. Therefore, treatment of obesity contribute to  prevention of many chronic diseases risk. Recent years, it has started to consider on effects on the gastrointestinal system in treatment of obesity as well as adequate and balanced diet, increasing  physical activity and lifestyle changes. Especially it was seen that gut microbiota has been associated with obesity. Many studies showed that gut microbiota may be vary with eating habits and obesity. It is discussed changed microbiota might be associated with obesity and many obesity-related diseases. It is thought that long term-controlled studies in this area   will create a new approach to the treatment of obesity and come into prominence in the fight against obesity. In this review,it was aimed to evaluate the relationship between body weight and the gut microbiota.

Aim: The aim of this study was to determine pressure ulcer prevention knowledge and attitudes among nurses who cared for surgical patients that were exposed to pressure ulcer risk factors such as immobilization and nutritional problems.

Materials and Method: This descriptive study was carried out with 150 nurses who were working in the surgical clinics and surgical intensive care units of a medical faculty hospital in XXXX and who had at least one year’s professional experience. Necessary permissions were obtained from the ethics committee and the institution prior to the research. Data were collected with a patient information form, the Pressure Ulcer Prevention Knowledge Assessment Instrument (PUPKAI) and the Attitude towards Pressure ulcer Prevention instrument (APuP) between October 1, 2018 and February 1, 2019.  Data were analyzed with the independent-samples t-test, the Mann-Whitney U test, the Kruskal-Wallis test, the correlation analysis and the multiple regression analysis.

Results: The mean age of the nurses was 29.91±6.48 years, 65.3% were female and half of them had undergraduate degrees. According to the PUPKAI total mean score (<60%), the pressure ulcer prevention knowledge of the nurses was inadequate and only 24% had a knowledge score ≥60%. Regression analysis results showed that, nurses' professional experience duration, working style, number of patients per shift and the experiences of giving care to patients with pressure ulcers were found to have a significant effect on the PUPKAI total mean score (p<0.05). According to the APuP total mean score (≥75%), the nurses had positive attitudes towards pressure ulcer prevention. It was also determined that the descriptive characteristics of the nurses did not significantly affect the APuP total mean score (p>0.05). There was no significant relationship between the total mean scores of the PUPKAI and APuP (p>0.05).

Conclusion: This study revealed that the surgical nurses had positive attitudes towards pressure ulcer prevention but they had inadequate knowledge about it. These findings highlight the need for institutional arrangements to ensure that nurses have access to evidence-based knowledge about pressure ulcer prevention.

Aim: It is important to identify allergens in reducing disease-related symptoms and improving quality of life in the allergic diseases. Therefore, we aimed to evaluate the frequency of aeroallergens in allergic patients in our region.

Method: 1078 patients (2-18 years) who applied to the pediatric allergy immunology outpatient clinic between September 2017- March 2018 were included to the study. The demographic and clinical characteristics of 642 patients with at least one allergic sensitization in the skin prick test were evaluated retrospectively. Total IgE levels, peripheral eosinophil counts in the blood, aeroallergen sensitivities in skin prick test were evaulated from the patient’s files. The study was approved by the Ethics Committee of the Alanya Alaaddin Keykubat Medical Faculty.

Results: In 642 of the patients (59.5%), a positive response was observed against at least one aeroallergen. Among patients, 34.8% had asthma, 73.7% had allergic rhinitis, 12.6% had atopic dermatitis, and 3% had chronic urticaria. 24.8% of the patients (159) had more than one allergic disease. When the evaulation of the patients with positive skin prick test, 57.3% were male and 42.7% were female. The mean age was 8.49 +/- 4.15 years. The sensitivity of house dust mites was the most common (76.1%). In the second and third frequency, molds (51.8% Alternaria alternata, 41.7% Claudosporum herbarum) and grass and cereal pollen (39.8%) sensitivity were observed. Other determined aeroallergen sensitivity frequencies were; weed pollen mixture (24.6%), trees pollen mixture (21.7%), cockroach (17.8%), cat hair (31.2%), olive tree (20%). The mean serum total IgE level was 215.6 IU/ml and the mean eosinophil count was 410.63/mm³.

Conclusion: Detection of responsible allergens is important to control symptoms and to give the chance the course of the disease with immunotherapy in the selected cases.

\r\n Brown tumors are benign, but locally aggressive tumors that may emerge as a rare complication of prolonged hyperparathyroidism. They may be clinically and radiologically confused with bone metastases. Browns tumors show increased metabolic activity on F-18 FDG-PET/CT just as metastatic bone lesions. In this study, we present a patient who underwent PET/CT to seek a primary focus with the presumed diagnosis of  multiple bone metastasis, and Brown tumor was suspected because no primary focus was detected on imaging and increased FDG enhancement was seen in parathyroid locations, and the diagnosis was confirmed with further investigations. Herein, we aimed to underline that Brown tumors should be kept in mind in the differential diagnosis in patients who are clinically and radiologically considered to have bone metastasis. 

The hydatid cysts that are common geographically over the world; causing serious complications and considered as a high recurrent average disease . In spite of the infective nature of the disease; the primary treatment is a surgical one . And in this point the surgery techniques and the using of the scolicidal agents is important to increase the chances of the successful treatment.

In the literature, there is not enough information about the determination of the most effective scolicidal substances. Therefore clinically there are different opinions in the using of the different agents

In this study, in –vitro we investigated the activity of some frequent used scolicidal substances related to the time . All the agents that used in our study for 20 minutes were successful. But we have seen that the earliest and the most effective response is noticed with praziquantel. These findings that demonstrate the success of praziquantel to kill E. granulosus are proposing to support the medical treatment.

To determine the ideal scolicidal material that will be used in the medical and the surgical E.granulosus treatment, and its side effects more efficiencies-study analysis must be performed

Objective: The aim of this study was to evaluate the effects of smartphone / social media use and sleep related variables on academic achievement in pre-clinical medical students.

Material and Methods: 226 students receiving pre-clinical medical education at the same institution were included in the study. All participants completed the Pittsburg Sleep Quality Index (PSQI), Social Media Addiction Scale - Adult Form (SMAS-AF), Smartphone Addiction Scale (SAS) and Personal Information Form prepared for the study. All participants were questioned Average Academic Marks (AAM).  The participants were categorized as low / medium / high risk according to the scores of smartphone addiction scale.

Results: According to the risk of smartphone addiction, the mean score of AAM of the group with low dependency risk was 71.8 ± 8, the mean score of AAM of the group with the middle risk dependency risk was 68.4 ± 8.77, and the mean score of AAM of the group with the high dependency risk was 67.4 ± 9.75. The mean scores of AAM of the low-risk group in terms of smartphone addiction were significantly higher than the high-risk group (p = 0.035). Similarly, when the total scores of the participants' social media addiction are examined; the average of the low-risk group was 40.4 ± 11.17, the average of the medium-risk group was 51.7 ± 9.2, and the average of the high-risk group was 50.8 ± 12.9. Social media addiction total scores of the high risk group in terms of smartphone addiction were significantly higher than the medium and low risk group (p <0.001). There was no significant difference between sleep times and PDQI total scores between groups. When the factors associated with AAM were analyzed by Pearson correlation analysis, a positive statistically significant relationship was detected with sleep efficiency (r = 0.19, p <0.001), while a significant negative correlation was observed with total SAS score and hours spent in bed (r = -23, p <0.001; r = -27, p <0.05, respectively). A multivariate hierarchical regression analysis model suggested that gender, sleep efficiency, SAS and SMASAF scores affected AAM.

Conclusion: Use of social media / smartphone by medical students can affect sleep habits and academic success during the period of pre-clinical education. Inclusion of training on conscious use of social media and smartphone and emphasizing the importance of sleep habits in medical education have the potential to contribute to the development of better-equipped physicians.
