Recognizing cardiac murmurs in childhood: a survey of physicians' approaches and knowledge levels.

OBJECTIVE: This study aimed to assess physicians' approach to cardiac murmurs and their level of knowledge about this sign, which is a crucial finding in childhood cardiac anomalies. METHODS: The study intended to include all family physicians in the Adiyaman province of Turkey, but ultimately 150 out of 210 physicians participated and was completed with a percentage response rate of 71%. Participants were asked about their approach to cardiac murmurs, answered knowledge questions, and completed a questionnaire on demographic characteristics. Subsequently, eight heart sounds were played, and participants were asked to identify the nature of each sound. RESULTS: Family medicine specialists (all scores were p < 0.001) and physicians who completed a pediatric internship lasting over a month (knowledge score p = 0.012, behavioral score p = 0.021, recording score p = 0.01) demonstrated significantly higher knowledge, approach, and recording scores. Age and years in the profession showed a negative correlation with recording scores. CONCLUSIONS: The study highlights the significant impact of various factors such as gender, specialization, internship duration, experience, and theoretical knowledge on the ability to recognize and approach cardiac murmurs. These findings underscore the importance of incorporating these factors into medical education and development programs, especially those aimed at improving cardiac examination skills.

Treatment initiation rates of patients with positive anti-hepatitis C virus results in tertiary hospitals in Turkey.

INTRODUCTION: The aim of this national, multicenter, cross-sectional, retrospective chart review study was to determine the proportion of patients in Turkey who received hepatitis C virus (HCV) treatment after receiving positive anti-HCV results during HCV screening. METHODOLOGY: Data related to patients' demographics, laboratory results, time interval from obtaining a positive anti-HCV result to treatment initiation, specialty of the physician requesting anti-HCV screening, and type of hospital were analyzed. RESULTS: Among 1,000 patients who received a positive anti-HCV result, 50.3% were male and 78.5% were screened for HCV-RNA. Among HCV-RNA screened patients, 54.8% (n = 430) had a positive result. Among patients who tested positive for HCV-RNA, 72.8% received HCV treatment in line with their positive anti-HCV results. The median time from obtaining a positive anti-HCV result to initiation of HCV treatment was 91.0 days (interquartile range 42.0 to 178.5). Non-surgical branches requested HCV-RNA testing more frequently than surgical branches (p < 0.001). The rate of access to HCV treatment was higher among patients screened in university hospitals than among patients screened in training and research hospitals (p < 0.001). CONCLUSIONS: Our results indicate a higher rate of treatment initiation among patients with HCV infection than is described in the published literature. Furthermore, the time from screening to treatment initiation was considerably shorter compared with other international studies. However, since HCV-RNA testing was not requested in a significant portion of patients with a positive anti-HCV test result, there might be a large patient population with HCV who do not receive treatment.

Evaluation of Scorpion Stings in Children.

INTRODUCTION: Scorpion stings are a significant public health problem in many parts of the world. Children are at a higher risk of developing severe complications from scorpion envenoming, including cardiac, respiratory, and neurologic complications. In Turkey, members of the Buthidae family are the most common culprits in severe envenoming events. METHODS: This retrospective-descriptive study was conducted in Turkey. Children aged 0 to 18 y admitted to the emergency department of Kahta State Hospital between December 2017 and December 2020 were included in the study. Patient information was reviewed, and 78 patients with complete demographic, laboratory, and clinical data were included in the study. RESULTS: Out of the 78 patients, 24.4% were six years old or younger while the 75.6% were older than six years. Alpha blocker was given to 12.8% of the patients, and antivenom was given to 43.6% of the patients. Of the 78 patients, 71.8% were followed up in the emergency department, 21.8% were followed up in the inpatient unit, and 6.4% were followed up in the intensive care unit. Two patients (2.6%) died within 1 month. There was a significant difference regarding lactate dehydrogenase value according to the sting site (P=0.014). Lactate dehydrogenase values of patients stung on the head and neck and upper extremity were higher than those of patients bitten on lower extremities. CONCLUSIONS: Elevated levels of specific laboratory parameters, such as leukocytes, aspartate transaminase, and lactate dehydrogenase, are linked to worse outcomes. Additionally, stings on the head, neck, and upper extremities are more strongly associated with severity. These findings guide tailored treatment strategies for scorpion stings, with the potential for further refinement through broader studies across diverse regions and populations.

Segmentation and classification of skin burn images with artificial intelligence: Development of a mobile application.

AIM: This study was conducted to determine the segmentation, classification, object detection, and accuracy of skin burn images using artificial intelligence and a mobile application. With this study, individuals were able to determine the degree of burns and see how to intervene through the mobile application. METHODS: This research was conducted between 26.10.2021-01.09.2023. In this study, the dataset was handled in two stages. In the first stage, the open-access dataset was taken from https://universe.roboflow.com/, and the burn images dataset was created. In the second stage, in order to determine the accuracy of the developed system and artificial intelligence model, the patients admitted to the hospital were identified with our own design Burn Wound Detection Android application. RESULTS: In our study, YOLO V7 architecture was used for segmentation, classification, and object detection. There are 21018 data in this study, and 80% of them are used as training data, and 20% of them are used as test data. The YOLO V7 model achieved a success rate of 75.12% on the test data. The Burn Wound Detection Android mobile application that we developed in the study was used to accurately detect images of individuals. CONCLUSION: In this study, skin burn images were segmented, classified, object detected, and a mobile application was developed using artificial intelligence. First aid is crucial in burn cases, and it is an important development for public health that people living in the periphery can quickly determine the degree of burn through the mobile application and provide first aid according to the instructions of the mobile application.

The Distribution and the Antimicrobial Susceptibility Features of Microorganisms Isolated From the Burn Wounds: A 10-Year Retrospective Analysis.

In this study, we aimed to evaluate the distribution features and antimicrobial susceptibility test results of the microorganisms isolated from the wounds of pediatric and adult patients with burn. The culture and susceptibility test results of the microorganisms, isolated from the wound swabs of the patients hospitalized in a tertiary-burn care center in 10-year period, were retrospectively screened on the microbiology department databases. Their distribution of isolated microorganisms regarding species and susceptibility test results were compared with previous studies. A total of 367 microorganisms, isolated from the burn wounds of 293 patients (13 ± 18.9 years, F/M: 0.93) (73 adults and 220 pediatric patients), were included in this study. A solitary agent was isolated in 239 (81.6%) patients, while 2 were isolated in 43 (14.7%) and 3 or more agents in 11 (3.8%). From these, 33% of the isolated microorganisms were gram-positive cocci, 61% were gram-negative bacteria, and 6% were Candida spp. The most common isolated microorganisms were Staphylococcus aureus (18.5%), Pseudomonas spp. (16.9%), and Escherichia coli (11.2%), while the least common was Streptococcus spp. (2.5%). Methicillin resistance was 15% among the S. aureus strains. No resistance was observed against levofloxacin, vancomycin, teicoplanin, linezolid, daptomycin, fusidic acid, and tigecycline in S. aureus strains. The highest resistance rates were observed against levofloxacin (64%), tobramycin (64%), pip/tazobactam (63%), imipenem (63%), and the lowest against colistin (5%) and ceftazidime (29%), among Pseudomonas spp. The most common causative agents in burn wound infections and their current antimicrobial susceptibility features should be well identified, in order for prevention of serious complications and optimal management the condition to occur.

Future expectation levels of adolescents during the COVID-19 pandemic.

Introduction: This study was aimed at examining the future expectations of high school students during the COVID-19 pandemic. Methods: A future expectation questionnaire was administered to 412 high school students, and the change in their expectations for the future during the COVID-19 pandemic period was questioned in this questionnaire. Results: Scale sub-scores and total scores of those who were infected with COVID-19 were significantly lower than those who were not (p < 0.001). The scale sub-scores and total scores of those whose relatives were infected with COVID-19 were significantly lower than those who were not (p < 0.05). The scale sub-scores and total scores of those who think that the pandemic will always continue, those who think that their education is disrupted due to the pandemic, those who think that the pandemic affects their choice of profession, and those who express that they look to the future with more hope than before the pandemic were found to be significantly lower (p < 0.05). Discussion: The future expectation is a more sensitive concept among adolescents than adults. During and after the pandemic, activities should be organized by considering the sensitivity of young people about their future expectations, and families and society should be made aware of this issue.

Computed Tomography and Magnetic Resonance Imaging for Congenital Hearing Loss: A Retrospective Study.

OBJECTIVE: The aim of this study is to evaluate the relationship between the cochlear nerve and the anatomical structures of the cochlea and internal acoustic canal in patients with congenital hearing loss. MATERIALS AND METHODS: Temporal tomography and magnetic resonance images of 44 patients (88 ears) with non-syndromic congenital hearing loss were retrospectively analyzed between 2018 and 2021. Patients were divided into 2 groups according to cochlear nerve hypoplasia. Cochlear nerve canal width, cochlear basal/ middle turn widths, and internal auditory canal widths were examined. RESULTS: Cochlear nerve hypoplasia was detected in 18.2% (n=16) of the patients and all of the patients with cochlear nerve hypoplasia had severe hearing loss. A statistically significant difference was found between the structures' widths in patients with and without cochlear nerve hypoplasia, in cochlear nerve canal and coronal width of the internal auditory canal. When stenosis is accepted as <1.4 mm for cochlear nerve canal and <3.80 mm for coronal width of the internal auditory canal, cochlear nerve hypoplasia differs statistically between the groups in measurements (respectively; P < .001, P=.018). CONCLUSIONS: In patients with sensorineural hearing loss, cochlear nerve hypoplasia may accompany. Anatomical structures are important in predicting cochlear nerve hypoplasia from temporal computed tomography. Cochlear nerve hypoplasia should be suspected if the cochlear nerve canal and coronal width of the internal auditory canal are less than 1.4 mm and 3.8 mm, respectively, on temporal computed tomography.

Pre- and post-treatment evaluation of routine blood analysis in patients with attention deficit hyperactivity disorder and comparison with the healthy control group.

This study aimed to examine potential disparities in hematologic inflammation parameters between children diagnosed with attention deficit hyperactivity disorder (ADHD) and their healthy counterparts and to determine whether atomoxetine treatment induced any alterations in inflammation indicators. This case-control study involved 43 children aged 6-13 years, 22 diagnosed with ADHD for the first time, and 21 healthy children. In all children, complete blood count and albumin, C-reactive protein (CRP), thyroid stimulating hormone (TSH), free thyroxine (free T4), folate, vitamin B12, aspartate aminotransferase (AST), alanine transaminase (ALT), creatinine and urea values were performed. Children with ADHD were started on atomoxetine treatment, and one month later, the blood test was repeated for those who commenced treatment. Neutrophil (p = 0.005), platelet (PLT) (p = 0.002), neutrophil/lymphocyte ratio (NLR) (p = 0.001), platelet/lymphocyte ratio (PLR) (p < 0.001), systemic immune /inflammation index (SII) (p < 0.001) and pan-immune-inflammation value (PIV) (p = 0.025) parameters were found to be significantly higher than the control group, while the lymphocyte value (p = 0.001) was found to be significantly lower. In those in the ADHD group, lymphocyte (p = 0.041) and albumin (p = 0.027) values increased significantly after treatment. The results of this study show the increase in inflammation in drug-naive ADHD patients and the partial improvement after treatment. However, there is a need to evaluate inflammation in larger samples after longer-term treatments and follow-ups.

Childhood Vaccine Attitude and Refusal among Turkish Parents.

We aimed to understand and resolve anti-vaccine attitudes by examining the factors associated with vaccine attitudes and exploring potential strategies to improve childhood vaccination rates. Between 2014 and 2021, a total of 628 families refused vaccination in Adiyaman. A total of 300 families accepted visits and were visited. During the visits, the families were administered a questionnaire to determine the reasons for vaccine rejection and their opinions on the matter. While providing general information about the vaccine, parents were encouraged to reconsider their decision, and at the end, parents completed the questionnaire. The questionnaire included sociodemographic questions, reasons for vaccine refusal, and a vaccine attitude scale. Among the participants in the study, 9.3% were convinced about the vaccine. The mean vaccine attitude scale score was calculated as 23.6 ± 2.5 (min = 15-max = 29). Significantly higher rates of persuasion were observed among fathers (17.3%) compared to mothers (7.7%) (p = 0.038). Participants who had received some vaccinations had a higher rate of persuasion (11.6%) compared to those who had not received any vaccinations (2.6%) (p = 0.02). Childhood vaccine refusal is a complex issue that has been the subject of numerous studies. Studies on this subject will increase awareness of vaccines.

COVID-19 Vaccination and Breastfeeding Mothers in Kahta District, Turkey.

We aimed to determine the attitudes and behaviors of breastfeeding mothers regarding the vaccine by examining their knowledge of the COVID-19 virus vaccine and their hesitations about it. The research is a cross-sectional and descriptive study conducted in the Kahta district of Adiyaman, a southeastern province in Turkey, between January and May 2022. The study population consisted of 405 mothers who applied to the Kahta State Hospital Pediatrics outpatient clinic. A questionnaire form was used as a data collection tool, and a consent form was obtained from the participants. The vaccination rate (89%) of those who graduated from high school and above was significantly higher than that of those who graduated from secondary school or below (77.7%). As the economic situation worsened, the vaccination rate decreased. The vaccination rate (85.7%) of mothers whose breastfed child was 0-6 months old was found to be significantly higher than that of those with 7-24-month-olds (76.4%) (p:0.02). The rate of being vaccinated (73.3%) of those who had a new type of COVID-19 virus infection was significantly lower than the rate of being vaccinated (86.3%) of those who did not have a COVID-19 virus infection. The vaccination rate of those who received information from their family doctor and the internet was higher than that of those who received information from radio/TV and people around. The rate of mothers thinking babies should stop breastfeeding who graduated from secondary school or below was higher (53.2%) than the rate of mothers who graduated from high school or above (30.2%) to be vaccinated against the COVID-19 virus. To eliminate the hesitancy about vaccination in mothers, it is necessary to inform and educate the whole society correctly, starting with families with low education and economic levels.

Spatial distribution of heavy metals in soils around cement factory and health risk assessment: a case study of Canakkale-Ezine (NW Turkey).

Sustainable use of agricultural land plays a crucial role in ensuring food security. For sustainable use of soils, it is very important to focus on the pollution status. This study was conducted on the soils in the northern part of the Ezine district in northwestern Turkey. The study aimed to determine the physicochemical properties of the soils in the vicinity of the cement plant, the concentrations of heavy metals, the spatial distribution of heavy metals, and their impact on the health of the local human population. Soil samples were collected from the cement plant in different directions (S,W, N, E, NE, SW) and at different distances (1, 3, 5, and 7 km) from 0-10 cm depth with three replicates. The soil samples were analyzed for texture, pH, electrical conductivity, lime, and heavy metals such as Cd, Co, Cu, Fe, Mn, Ni, Pb, and Zn. The soils had different textures (loam, sandy clay loam, loam, sandy loam), slightly alkaline pH, low lime content, and moderate organic matter content. Except for Cd and Pb, the average values of the other heavy metals (Co = 1.18 < 19 mg kg-1,Cr = 50.92 < 90 mg kg-1, Cu = 31.21 < 45 mg kg-1, Fe = 16,007 < 47,200 mg kg-1, Mn = 499.68 < 850 mg kg-1, Ni = 41.17 < 68 mg kg-1, Zn = 50.91 < 95 mg kg-1) in the soils were below the normal background level. The heavy metal contents of the soils in the study area are influenced by various sources (geological structure, agrochemicals used in agricultural activities, and vehicle traffic). The prevailing wind direction did not influence the local distribution of heavy metals in soils in the study area. The health risk assessment model studies showed that the hazard quotient values of less than 1 for adults and children indicate that the noncarcinogenic risks were insignificant. People exposed to heavy metals in the soils of the study area contaminated from various sources for a long time could be at carcinogenic risk. Since Cr and Pb exceed the acceptable risk range in children and Cr exceeds the acceptable risk range in adults, geochemical monitoring of soils should be conducted periodically by authorized institutions in the study area.

The Relationship Between Digital Game Addiction and Loneliness and Social Dissatisfaction in Adolescents.

Background In this study, it was aimed to examine digital addiction, loneliness and social dissatisfaction among adolescents studying in Adiyaman, Turkey, and to determine the relationship with each other. Methodology Digital Game Addiction Scale for Children (DGASFC) and Loneliness and Social Dissatisfaction Questionnaire (LSDQ) were administered to 634 middle and high school students. A questionnaire form was used as a data collection tool. Results DGASFC scores and LSDQ scores were found to be higher in males, in high school students, in those whose parents' education level was high school or above, in those whose parents lived separately, in those with good economic status, in those who were younger, and in those who were not restricted by their families. A significant positive correlation was found between DGASFC and LSDQ scores. Conclusions Digital addiction should be followed closely in terms of accompanying disorders or pathologies that predispose to it. In our study, it was found that digital game addiction, loneliness and social dissatisfaction decreased with age. However, this applies separately to middle school and high school groups. Because, despite their older age, high school adolescents have been found to be more digitally dependent, lonely and socially dissatisfied than secondary school students. Contrary to the studies in the literature, the risk of digital addiction, loneliness and social dissatisfaction was found to be low in those with low economic status.

Characteristics and outcomes of COVID-19 patients with IPF: A multi-center retrospective study.

BACKGROUND: There are few data on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (COVID-19) infection in patients with idiopathic pulmonary fibrosis (IPF). The objective of this study is to describe the characteristics and outcomes of IPF patients confirmed COVID-19 infection. METHODS: In this retrospective, multi-center, cohort study, patients from 4 hospital medical records with known IPF and a COVID-19 diagnosis were identified. Demographic and clinical outcome data were abstracted through a review of electronic medical records. RESULTS: Records for 46 patients with IPF and COVID-19 were abstracted. The mean age was 65±10 years. The most common symptom was dyspnea, followed by fever and cough. Ground-glass opacities (n = 35, 83.3%) and consolidations (n = 11, 26.1%) were the main imaging features of the disease in thorax computed tomography (CT). Twenty-four patients (52.1%) required hospitalization. Among the hospitalized patients, 16 (66.6%) were admitted to the intensive care unit (ICU), and 10 (41.6%) underwent invasive mechanical ventilation. Thirteen patients (28.2%) died of COVID-19 complications. Mortality rate was significantly associated with lower DLCO/VA, long term oxygen therapy and consolidation finding on CT of thorax (p<0.05). On multivariable analysis, neither factor was associated with hospitalization or mortality. CONCLUSIONS: IPF patients represent a vulnerable population for COVID-19, according to the high rate of hospitalization, ICU requirement, and mortality rate. Measures to minimize the risk of COVID-19 infection remain key to protect IPF patients.

The Epidemiology, Clinical Manifestations, Radiology, Microbiology, Treatment, and Prognosis of Echinococcosis: Results of NENEHATUN Study.

Aim: Echinococcosis, caused by Echinococcus species, is an important zoonotic disease causing major health problems in humans and animals. Herein, we aimed to evaluate the epidemiology, clinical and laboratory parameters, radiological, serological, pathological, and treatment protocols of followed-up cases of hydatidosis. Methods: A total of 550 patients diagnosed with hydatid cyst disease were included in this study. Patients who were positive for one or more of the enzyme-linked immunosorbent assay or indirect hemagglutination test, pathological results, or radiological findings were examined. The data analyzed were collected from nine centers between 2008 and 2020. Records were examined retrospectively. Results: Among the patients, 292 (53.1%) were women and 258 (46.9%) were men. The patients' mean age was 44.4 ± 17.4 years. A history of living in rural areas was recorded in 57.4% of the patients. A total of 435 (79.1%) patients were symptomatic. The most common symptoms were abdominal pain in 277 (50.4%), listlessness in 244 (44.4%), and cough in 140 (25.5%) patients. Hepatomegaly was found in 147 (26.7%), and decreased breath sounds were observed in 124 (22.5%) patients. Radiological examination was performed in all cases and serological methods were also applied to 428 (77.8%) patients. The most frequently applied serological test was IHA (37.8%). A single cyst has been found in 66% patients. Hepatic involvement occurred in 327 (59.4%), pulmonary involvement was found in 128 (23.3%), whereas both of them were recorded in 43 (7.8%) patients. Splenic involvement was only detected in nine (1.6%) patients. Echinococcus granulosus (72.5%) was most frequently detected. Cyst diameters of 56.9% of the patients were in the range of 5-10 cm. A total of 414 (75.2%) patients received albendazole as an antiparasitic. Mortality was noted in nine (1.6%) patients. Conclusion: Echinococcosis is an important public health problem in Turkey. It can affect the social, economic, and political structures of the community. Public education and awareness are extremely important.

Comparison of Conventional Methods, Automated Systems, and DNA Sequence Analysis Methods in the Identification of Corynebacterium afermentans and Corynebacterium mucifaciens Bacteria Isolated from Blood and Catheter Culture Samples.

The aim of this study is to compare different methods due to the difficulties in identifying coryneform bacteria to species level and to determine antibiotic resistance profiles. Isolates identified as Turicella otitidis (n:45) by VITEK 2 Compact and Corynebacterium mucifaciens (n:1) by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS), isolated from blood and catheter cultures between 2015 and 2017 were included in the study. For identification of the isolates, conventional tests and 16S rDNA sequence analysis were performed. Antibiotic susceptibilities of the isolates were determined by Etest. The isolates identified as T. otitidis with VITEK 2 Compact could not be identified by MALDI-TOF MS and described as C. mucifaciens/Corynebacterium afermentans spp. by 16S rDNA sequence analysis. One isolate identified as C. mucifaciens by MALDI-TOF MS could not be identified with VITEK 2 Compact and described as C. mucifaciens by 16S rDNA sequence analysis and conventional methods. All isolates (n:45) described as C. mucifaciens/C. afermentans spp. by 16S rDNA sequence analysis were identified as C. afermentans subsp. afermentans with conventional methods. All 45 isolates identified as C. afermentans subsp. afermentans were resistant to penicillin, erythromycin, and clindamycin and were susceptible to vancomycin and daptomycin, whereas 31 (69%) were resistant to trimethoprim-sulfamethoxazole (TMP-SXT). The isolate identified as C. mucifaciens was susceptible to penicillin, vancomycin, daptomycin, and TMP-SXT; it was resistant to erythromycin and clindamycin. In this study, we reported 45 C. afermentans isolates misidentified as T. otitidis in routine laboratory processes. To our knowledge, this is the first study to include the highest number of C. afermentans blood isolates.

The evaluation of vancomycin-resistant enterococci and carbapenamase producing Klebsiella colonization among ICU-Hospitalized Patients.

Background: Multi-drug resistant organisms, especially Vancomycin-Resistant Enterococcus (VRE) and Carbapenam Resistant Klebsiella pneumoniae (KPC), are serious health threat. Early detection of resistant bacteria colonization among patients in intensive care units (ICUs) not only enables effective treatment but more importantly prevents disease and limits transmission. Therefore, we aimed to to assess the frequency of VRE and KPC colonization via rectal swab sampling. Methods: The study was carried out in ICUs of a tertiary hospital. Two rectal swab samples were collected within the first 24 hours of admission and another one was taken every subsequent 15 days to test for for VRE and KPC carriage. Results: A total 316 rectal swab samples taken from 230 patients. Forty-seven patients were screened at least 2 times. 183 patients were not further screened due to discharge, exitus or transfer to other wards. Thirty-six patients (16%) were determined to be VRE (+). The most frequently isolated strain was E. faecium (80.5%) and its most common genotype was VanA (87.5%). Seven patients (3%) were identified as KPC (+). OXA-48 type crbapenamase was confirmed in all KPC isolates. Conclusion: This study shows that VRE and KPC colonization continues to be a serious threat in ICUs.

The diagnostic utility of the "Thwaites' system" and "lancet consensus scoring system" in tuberculous vs. non-tuberculous subacute and chronic meningitis: multicenter analysis of 395 adult patients.

BACKGROUND: Tuberculous meningitis (TBM) represents a diagnostic and management challenge to clinicians. The "Thwaites' system" and "Lancet consensus scoring system" are utilized to differentiate TBM from bacterial meningitis but their utility in subacute and chronic meningitis where TBM is an important consideration is unknown. METHODS: A multicenter retrospective study of adults with subacute and chronic meningitis, defined by symptoms greater than 5 days and less than 30 days for subacute meningitis (SAM) and greater than 30 days for chronic meningitis (CM). The "Thwaites' system" and "Lancet consensus scoring system" scores and the diagnostic accuracy by sensitivity, specificity, and area under the curve of receiver operating curve (AUC-ROC) were calculated. The "Thwaites' system" and "Lancet consensus scoring system" suggest a high probability of TBM with scores ≤4, and with scores of ≥12, respectively. RESULTS: A total of 395 patients were identified; 313 (79.2%) had subacute and 82 (20.8%) with chronic meningitis. Patients with chronic meningitis were more likely caused by tuberculosis and had higher rates of HIV infection (P < 0.001). A total of 162 patients with TBM and 233 patients with non-TBM had unknown (140, 60.1%), fungal (41, 17.6%), viral (29, 12.4%), miscellaneous (16, 6.7%), and bacterial (7, 3.0%) etiologies. TMB patients were older and presented with lower Glasgow coma scores, lower CSF glucose and higher CSF protein (P < 0.001). Both criteria were able to distinguish TBM from bacterial meningitis; only the Lancet score was able to differentiate TBM from fungal, viral, and unknown etiologies even though significant overlap occurred between the etiologies (P < .001). Both criteria showed poor diagnostic accuracy to distinguish TBM from non-TBM etiologies (AUC-ROC was <. 5), but Lancet consensus scoring system was fair in diagnosing TBM (AUC-ROC was .738), sensitivity of 50%, and specificity of 89.3%. CONCLUSION: Both criteria can be helpful in distinguishing TBM from bacterial meningitis, but only the Lancet consensus scoring system can help differentiate TBM from meningitis caused by fungal, viral and unknown etiologies even though significant overlap occurs and the overall diagnostic accuracy of both criteria were either poor or fair.

Impact of urbanization on soil loss: a case study from sod production.

The rapidly increasing population of urban centers leads to the increasing need for greenspaces. Sodding of turfgrass provides instant greenspace, but it removes soil from sod farms. The extent of such removal has not been widely quantified. The amount quantity of soil and organic matter lost with sod harvest and the associated cost of nutrients lost from six sod farms in the Marmara region of Turkey were determined. Soil loss ranged from 166 to 243 Mg ha-1 year-1, while the associated organic matter loss ranged from 1 to 6 Mg ha-1 year-1. The amount of soil loss increased with increases in gravimetric water, clay, and silt contents, and duration under sod harvest, while it decreased with an increase in sand content. Annual nutrient lost ranged from 117 to 449 kg ha-1 for N, from 2 to 18 kg ha-1 for P2O5, and from 21 to 175 kg ha-1 for K2O. Replacing the nutrient lost would cost about $134 ha-1 year-1 for sandy soils and $444 ha-1 year-1 for fine-textured soils. Soil lost with sod harvest was 134 times higher than that from agricultural lands by erosion in the region, although the area under sod production is much smaller than that under croplands. Similarly, organic matter loss was 4 to 5 times higher than the accumulation rate under established turfgrass in golf courses and lawns in locations with similar climate. Overall, sod harvesting results in significant and costly soil, organic matter, and nutrient loss, which, although small in area, can be an important component of total soil erosion.

[The Microbiological Analysis of a Rhizobium radiobacter Outbreak After Intravitreal Injection]. / Intravitreal Enjeksiyon Sonrasi Ortaya Çikan Rhizobium radiobacter Salgininin Mikrobiyolojik Analizi.

Rhizobium radiobacter, which is found in nature and causes tumorigenic plant diseases can lead to opportunistic infections, especially in people with underlying diseases. In our study, endophthalmitis that observed in ten patients caused by R.radiobacter bacteria after intravitreal ranibizumab injection in Ophthalmology Clinic were examined microbiologically. Vitreous fluid samples of 13 patients who received intravitreal ranibizumab injection were sent to the Microbiology Laboratory from Van Yuzuncu Yil University Faculty of Medicine's Ophthalmology Clinic for microbiological examination in December 21, 2016. Samples were examined under microscope after staining with Gram and cultured with 5% sheep blood agar and Eosin Methylene Blue (EMB) agar. The culture plates were incubated for 18-24 hours at 37°C in 5% CO2. At the end of this period, catalase, oxidase, and urease tests were performed on the colonies. The identification and antibiotic susceptibility tests of microorganisms growing in vitreous fluid samples were performed using BD Phoenix (Becton Dickinson, USA), Vitek 2 Compact (BioMerieux, France), and Vitek MS (BioMerieux, France) systems. In addition, 16S rDNA sequence analysis was performed and the pulsed field gel electrophoresis (PFGE) method was used to determine the clonal relationship between the isolates. After growing in cultures (one day after the procedure), culture samples were collected from the objects, medical tools and equipment, hands of healthcare staff and a new injection solution in the area where the procedure was performed. R.radiobacter was isolated in 10 of the vitreous fluid samples of 13 patients, and no bacterial growth was detected in 3. The microorganisms were found to be gram-negative bacilli, non-fermenter, motile, catalase/oxidase/urease positive, in compliance with R.radiobacter. All isolates were identified as R.radiobacter by BD Phoenix (Becton Dickinson, USA), Vitek 2 Compact (BioMerieux, France), and Vitek MS (BioMerieux, France) (database v2.0) systems. R.radiobacter isolates were found to be resistant to ampicillin, amoxicillin/clavulanate, trimethoprim/ sulfamethoxazole, cefotaxime and ceftazidime; susceptible to cefuroxime, cefepime, amikacin, gentamicin, imipenem, meropenem, ciprofloxacin, levofloxacin and piperacillin/tazobactam. The isolates were identified as R.radiobacter by 16S rDNA sequence analysis. PFGE showed that all isolates had the same band profile. R.radiobacter isolates with the same band profile likely revealed that the contamination was from the same source. However, the growth of R.radiobacter was not detected in the cultures made from the objects, medical instruments and supplies, the hands of healthcare professionals and the new injection solution in the area where the procedure was performed, and the source of the agent could not be determined. The results have shown that intravitreal injection procedure carries a risk for R.radiobacter infection. Disinfection and antisepsis conditions, before and during the procedure, is important for the prevention of such infections. This study is the first epidemic outbreak report of endophthalmitis caused by the same strain of R.radiobacter and the second article in which R.radiobacter was reported as the cause of endophthalmitis after intravitreal injection.

[In-vitro Activity of Ceftolozane-Tazobactam in Combination with Various Antibiotics Against Multidrug-resistant Acinetobacter baumannii Isolated from Intensive Care Patients]. / Yogun Bakim Hastalarindan Izole Edilen Çoklu Antibiyotik Dirençli Acinetobacter baumannii Izolatlarinda Seftolozan-Tazobaktamin Çesitli Antibiyotik Kombinasyonlari ile In Vitro Etkinliginin Arastirilmasi.

Acinetobacter species lead to nosocomial infections in immunocompromised patients hospitalized in intensive care units or services. Acinetobacter baumannii is a bacterium that is difficult to treat because it is intrinsically resistant to many antibiotics and can develop resistance afterwards. This situation limits the use of existing antibiotics and directs the clinician to new agents, different treatment options and the use of various antibiotic combinations. The aim of this study was to determine the sensitivities of doripenem (DOR), tigecycline (TGC), minocycline (MIN), amikacin (AK) and a newly developed agent ceftolozane-tazobactam (CT) in multidrug resistant A.baumannii strains which were isolated from inpatients in intensive care units and to investigate the in vitro interactions of CT/DOR, CT/TGC, CT/MIN and CT/AK combinations by using antibiotic gradient test method. Thirty-five A.baumannii strains isolated from various clinical specimens (blood, urine, sputum, tracheal aspirate, wound, abscess and catheter) between January 2017 and July 2017 were included in the study. Strains isolated from inpatients in intensive care units and resistant to at least three antibiotic classes were selected. The identification of A.baumannii isolates and the determination of routine antibiotic susceptibility profile were performed according to EUCAST 2017 criteria by the use of BD Phoenix 100 (Becton Dickinson, USA) automated system. Minimum inhibitor concentration values of CT, DOR, TGC, MIN, AK and combinations of CT with four other antibiotics (CT/DOR, CT/TGC, CT/MIN and CT/AK) were determined by antibiotic gradient test method. Fractional inhibitor concentration index (FICI) was used to determine the interactions of the combinations in vitro. According to the data obtained; the FICI was evaluated as synergy if FICI ≤ 0.5, additive if 0.5 > FICI ≤ 1, indifferent (unidentified interaction) if 1
