The relationship between oral health and sleep quality in community-dwelling older adults.

Introduction: The assessment of the sleep status of older adults and its relationship to oral health can help determine their well-being and quality of life. In accordance with this purpose, we aimed to evaluate the relationship between oral health and sleep quality in community-dwelling older adults in an urban area. Materials and Methods: The data of this study were taken from the Kayseri Elderly Health Study. The study group was administered a questionnaire form and the Pittsburgh Sleep Quality Index. A specialist dentist examined the oral health conditions (dentures use; caries; deficient, filled, natural teeth numbers; periodontal health) using the Community Periodontal Index and the Oral Health Impact Profile-14 (OHIP-14-TR). Results: One hundred forty (38.1%) of the study group were female, and 227 (61.9%) were male. When evaluated in terms of oral hygiene, there was a statistically significant difference between those with good sleep quality and poor sleep quality in terms of mechanical interventions such as using toothpaste and an inter-dental brush, and also, OHIP-14-TR was significant. In the binary logistic regression analysis, OHIP-14-TR was found to be a significant risk factor, reflecting only the subjective interpretation of the older adults in terms of oral health-related quality of life (odds ratio: 1.069, 95.0% confidence interval: 1.043-1.096). Conclusion: This is the first epidemiologic study to examine the relationship between oral health status and sleep quality, in which many oral health indicators are evaluated together in Turkish community-dwelling older adults. OHIP-14-TR may be a useful tool to employ in sleep disorder clinics for older people.

Aberrant patterns of PET response during treatment for DLBCL patients with MYC gene rearrangements.

PURPOSE: MYC gene rearrangements in diffuse large B-cell lymphoma (DLBCL) patients are associated with poor prognosis. Our aim was to compare patterns of 2[18F]fluoro-2-deoxy-D-glucose positron emission tomography computed tomography (PET/CT) response in MYC + and MYC- DLBCL patients. METHODS: Interim PET/CT (I-PET) and end of treatment PET/CT (EoT-PET) scans of 81 MYC + and 129 MYC- DLBCL patients from 2 HOVON trials were reviewed using the Deauville 5-point scale (DS). DS1-3 was regarded as negative and DS4-5 as positive. Standardized uptake values (SUV) and metabolic tumor volume (MTV) were quantified at baseline, I-PET, and EoT-PET. Negative (NPV) and positive predictive values (PPV) were calculated using 2-year overall survival. RESULTS: MYC + DLBCL patients had significantly more positive EoT-PET scans than MYC- patients (32.5 vs 15.7%, p = 0.004). I-PET positivity rates were comparable (28.8 vs 23.8%). In MYC + patients 23.2% of the I-PET negative patients converted to positive at EoT-PET, vs only 2% for the MYC- patients (p = 0.002). Nine (34.6%) MYC + DLBCL showed initially uninvolved localizations at EoT-PET, compared to one (5.3%) MYC- patient. A total of 80.8% of EoT-PET positive MYC + patients showed both increased lesional SUV and MTV compared to I-PET. In MYC- patients, 31.6% showed increased SUV and 42.1% showed increased MTV. NPV of I-PET and EoT-PET was high for both MYC subgroups (81.8-94.1%). PPV was highest at EoT-PET for MYC + patients (61.5%). CONCLUSION: MYC + DLBCL patients demonstrate aberrant PET response patterns compared to MYC- patients with more frequent progression during treatment after I-PET negative assessment and new lesions at sites that were not initially involved.

In-silico Analysis of Mt-CO1 Gene of Taenia Hydatigena Sheep Isolates.

Taenia hydatigena is a tapeworm that affects herbivores in different regions of the world. Cysticercus tenuicollis (larvae of T. hydatigena), is prevalent in ruminants and pigs. In the current study, phylogenetic analysis of the published mt-CO1 gene of C. tenuicollis sheep isolates was analyzed using in-silico method and vertical and horizontal transmission at the global level by using a meta-analysis approach. A total of 82 mt-CO1 nucleotide sequences (339 bp) of C. tenuicollis sheep isolates from the NCBI database (Italy -Sardinia-, Iran, Palestine, Iraq, Finland, India and China) were used to investigate haplotype and genetic relationships. Tajima's D (-2,2984) value was negative for the mt-CO1 sequences signifying the population expansion and/or purifying selection. The highly negative Fu's Fs (-60,528) values determined for the sequences reflecting the existence of uncommon haplotypes. The mt-CO1 of C. tenuicollis haplotype network had 47 haplotypes arranged within a star-like configuration with a main haplotype, which encompassed 25.6 % of the total isolates. In the mt-CO1 haplotype network analyzed, there were 80.5 % unique single haplotype and highest ratio was observed in C. tenuicollis from sheep originating from Iran, followed by Sardinia, Palestine and Finland. If the current condition continues, genetic differences in T. hydatigena will be able to rise, and possible new strains and/or genotypes that may influence the host adaptation and life cycle of the parasite may emerge.

INFLAMMATORY CELL RATIOS IN THE PATIENTS WITH FIBROMYALGIA.

Fibromyalgia is a chronic disease with undefined aetiology which commonly results in muscle sensitivity, pain, and sensitivity at certain anatomical points. The pathogenesis and aetiology of fibromyalgia are not yet fully understood. The objective of this study was to assess the diagnostic value of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), and lymphocyte/ monocyte ratio (LMR) as simple systemic inflammatory response biomarker sin patients with fibromyalgia. A total of 489 patients with fibromyalgia (group1) and 227 healthy controls (group2) were included in the study. Demographic data, Body Mass Index (BMI) neutrophil, lymphocyte and platelet counts, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels were recorded. Baseline NLR, PLR, and LMR were calculated by dividing the absolute neutrophil, platelet and lymphocyte counts by the respective divisor absolute values. The NLR, PLR, and LMR levels of the two groups were then compared. There were no significant differences in gender and age between the two groups (p>0,05). BMI levels (29.6 vs 24.8 kg/m2), mean NLR (3.63 vs. 2.11) and PLR (222.55 vs. 114.28) values were found to be statistically higher (p <0.001), and mean LMR (2.73 vs. 3.85) values were found to be statistically lower, in the patient group (p <0.001). The present study showed that NLR, PLR, AND LMR levels can be used in the diagnosis of fibromyalgia and systemic inflammation may play a role in fibromyalgia.

Cesarean section: requested mode of delivery?.

AIM: To constitute accurate policies for reducing the cesarean section (C/S) the authors evaluated the attitudes and knowledge of health workers and public population towards the mode of delivery, C/S on demand, and delivery complications in a large population. MATERIALS AND METHODS: 1,892 female volunteers in reproductive age were enrolled in the study and 589 of them were health workers. Patients were evaluated with questionnaire about their delivery mode and their answers were analyzed. RESULTS: The overall cesarean rate of the study population was 45.4%. This rate were 51.4% and 28.2%, respectively, for the health workers and public group (p < 0.001). Medical indication ratio ivere 57.7% and 40.1% for the healthcare group and the public population respectively and 20.2% of health workers and 13.9% of the public group had C/S by their preference without any medical indications (p < 0.001). CONCLUSION: C/S rate is high in Turkey and an action plan is needed to decrease the rate. When a patient's preference towards the mode of the delivery is C/S on demand, obstetricians, in their capacity as patient advocate, should help guide their patient through the sophisticated detailed medical information toward a decision that respects both the patient's attitude and the physician's obligation to optimize the health of both the mother and the newborn.

Association of Circulating Irisin with Insulin Resistance and Oxidative Stress in Obese Women.

Irisin is a myokine/adipokine with potential role in obesity and diabetes. The purpose of the present study was to assess irisin levels and its association with insulin resistance and oxidative stress markers in premenopausal normal-weight and obese women. Ten obese (mean body mass index, 32.65±3.04 kg m-2) and 10 normal-weight (23.00±2.23 kg m-2) premenopausal women were involved in the present study. Anthropometric, and body composition parameters, blood chemistry, oxidative stress markers, and irisin concentrations of different groups were measured. Correlation analyses were performed between irisin and other measured parameters. Plasma irisin levels were lower in the obese group than the normal-weight group (p<0.05). Glucose, homeostasis model assessment index (HOMA-IR), and MDA levels in the obese group were higher than that in the normal-weight group (p<0.05). Plasma irisin was negatively correlated with insulin (r=-0.648, p<0.05), HOMA-IR (r=-0.664, p<0.05) and MDA (r=-0.690, p<0.05). These data suggest that irisin levels are decreased with obesity, and irisin may have an antidiabetic and antioxidant effects.

Differential activation and expression of insulin receptor substrate 1 (IRS1) in mononuclear cells of type 2 diabetes patients after insulin stimulation.

Insulin regulates the glucose homeostasis by inducing tyrosine phosphorylation of insulin receptor substrate (IRS) proteins. IRS1 is the best studied member of this family and insulin-induced Tyrosine phosphorylation of (YXXM) motifs provides docking site for SH2 domain-containing proteins. Recent studies have suggested that genetic and/or environmental factors may affect the expression and phosphorylation levels of IRS1, and these could be important for development of insulin resistance. To shed light to the molecular basis of type 2 diabetes we wanted to determine whether YXXM motifs are genetically modified in these patients. We have isolated mononuclear cells of eighteen type 2 diabetes patients and prepared genomic DNA and protein lysates from these cells. The genomic DNA was used to sequence IRS1 gene, and protein lysates were used to determine the expression and phosphotyrosine levels of IRS1 after insulin stimulation. Although, we did not detect any mutations at/or near the YXXM coding regions in patients' DNA, immunprecipitation analysis of IRS1 indicated decreased levels of expression and tyrosine phosphorylation of IRS1 in patient's samples compared to that of healthy controls. Our results suggest that mononuclear cells of patients can be used to test the levels of insulin responsiveness before therapy.

Perinatal outcomes of borderline diabetic pregnant women.

We examined the perinatal outcomes of borderline diabetic pregnant women who had impaired 50 g oral glucose challenge test (OGCT) results, but normal 100 g oral glucose tolerance test (OGTT) results. Our study group included 70 pregnant women who had increased 50 g OGCT results, but normal 100 g OGTT results, and a control group of 122 pregnant women with normal 50 g OGCT results. Polyhydramnios, macrosomia and neonatal birth weight were significantly higher in the study group. After adjusting the results for possibly affecting variables, the risk of polyhydramnios remained significant, while the risk of macrosomia and neonatal birth weight was not significant between the groups. The results from the study group were similar to the control group, when adjusted for other risk factors. Increased 50 g OGCT results in pregnant women can be accepted as a benign state if the 100 g OGTT results are normal.

Neuroprotective effects of carvacrol and pomegranate against methotrexate-induced toxicity in rats.

BACKGROUND: Studies related to the use of various antioxidant and anti-inflammatory drugs to decrease the toxic side effects related to MTX have been carried out. However, since no medicine providing full protection against the side effects of MTX has been discovered, the discovery of new agents is required. AIM: The aim of this study was to determine whether methotrexate (MTX) causes oxidative stress and an inflammatory response in sciatic nerve, as well as whether carvacrol (CAR) and pomegranate (POM) have protective effects against the resulting oxidative stress and inflammatory response. MATERIALS AND METHODS: 32 adult male Wistar albino rats were used in the study. The animals were divided into 4 groups: Group C: the rats were not given any medication; Group MTX: On study day 2, the rats were given a single dose of 20 mg/kg MTX, administered intraperitoneally; Group MTX+CAR: On study day one, the rats were administered a single dose of 73 mg/kg CAR intraperitoneally. On study day two, a single dose of 20 mg/kg MTX was administered intraperitoneally; Group MTX+POM: For seven days starting from the study day one, rats were given 225 mg/kg POM extract once a day through orogastric gavage. On study day two, a single dose of 20 mg/kg MTX was administered intraperitoneally. All animals were sacrificed on the day eight. TOS, TAS, MDA, TNF-α and IL-1ß levels were evaluated in the sciatic nerve tissue. RESULTS: In comparison to the control group, a decrease in TAS levels and an increase in TOS, MDA, IL-1ß and TNF-α levels were detected in the MTX group. Compared to the MTX group, the MTX+CAR group had a significant increase in TAS level and significant decreases in TOS, MDA, IL-1ß and TNF-α levels. In comparison to the MTX group, the MTX+POM group had a significant decrease in MDA, IL-1ß and TNF-α levels. When the MTX+CAR and MTX+POM groups were compared, the TNF-α level measured was lower in the MTX+CAR group. CONCLUSIONS: In this work, we have shown that MTX causes a significant oxidative stress and inflammatory response in rats' sciatic nerve tissue and that CAR had an antioxidant effect in this system. Furthermore, we have proven, for the first time, that both CAR and POM decreased the pro-inflammatory response.

Job satisfaction in primary care after the health reform in a province of Turkey.

OBJECTIVE: Health care reform, which started to be restructured after the Alma Ata Declaration, positively contributed to the development of primary health care administrations around the world. In Turkey, the Ministry of Health launched a "Health Transformation Program" by initiating the "Family Medicine Model" that influenced the working conditions and job satisfaction of primary health care workers (PHCWs). In this cross-sectional study, we evaluated job satisfaction levels of PHCWs and the factors affecting these levels a decade after the introduction of the health care reform in a province of Turkey. PATIENTS AND METHODS: A total of 223 PHCWs participated in the study and completed a structured questionnaire that probed their views regarding their jobs and working conditions. Additionally, the short version of the Minnesota Satisfaction Questionnaire (MSQ) was administered to each participant. Participants were also asked to indicate whether they had any intention to quit their job, whether they liked their profession and workplace, and whether they were satisfied with their job. Bivariate analysis and binary logistic regression analysis were performed to determine predictors of job satisfaction. RESULTS: PHCWs were found to be generally dissatisfied with their working conditions and they declared that they were not sufficiently qualified to work in primary care. Their overall satisfaction was found to be moderate (3.21±0.67 out of 5) and the most important predictor for job satisfaction was found to be "Liking the workplace" (OR=3.07; 95% CI=1.46-6.45). CONCLUSIONS: The results indicated that environmental factors for job-related issues need to be examined more intensively for future planning and policy making in primary care.

Genetic, haplotype and phylogenetic analysis of Ligula intestinalis by using mt-CO1 gene marker: ecological implications, climate change and eco-genetic diversity.

Ligula intestinalis is a cestode parasite that affects freshwater fish in different countries of the world. The current study aims to reveal the phylogenetic, genetic and haplotype diversity of mt-CO1 gene sequences sent to the NCBI database from different countries by using in-silico analysis. The 105 mt-CO1 (371 bp) gene sequences of L. intestinalis obtained from NCBI were used for bioinformatics analyses. Sequences were subjected to phylogenetic and haplotype analysis. As a result of the haplotype analysis of L. intestinalis, 38 haplotypes were obtained from 13 different countries. Hap24 constituted 44.76% of the obtained haplotype network. Changes in nucleotides between haplotypes occurred at 1-84 different points. China and Turkey have highest fixation index (Fst) values of 0.59761, while the lowest (-0.10526) was found between Russia and Turkey. This study provides a baseline for future studies on extensive scale on the epidemiology, ecological aspects, distribution pattern, transmission dynamics and population dispersion of L. intestinalis worldwide.

The role of neutrophil albumin ratio in predicting the stage of non-small cell lung cancer.

OBJECTIVE: Inflammation forms the basis of cancer development and progression. It causes changes in complete blood count parameters, such as neutrophil counts. Low albumin levels are associated with poor prognosis in cancer patients. We aimed to investigate the association between neutrophil to albumin ratio (NAR) and the stage of non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: 257 NSCLC patients (24 females and 198 males) were included in the study. Patients were divided into two groups. Group 1 (n=61) included patients with early stage cancer (stage 1 and 2), while group 2  (n=196) included those with advanced stage cancer (stage 3 and 4). Demographic data, neutrophil, lymphocyte, platelet, white blood cell counts (WBC), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), ferritin and albumin levels at the time of diagnosis were recorded. The NAR of 2 groups were compared. RESULTS: There were no significant differences between the lymphocyte count (2.0 vs. 2.0 103/mm3) and platelet count (291 vs. 311 103/mm3) of the two groups (p > 0.05). ESR (38.8 vs. 57.5 mm/h), CRP (158 vs. 57 mg/l), ferritin (85 vs. 261 ng/ml), WBC count (8.6 vs. 10.6 103/mm3), neutrophil count (5.6 vs. 7.5 103/mm3), albumin values (2.9 vs. 3.7 gr/dl), and (p < 0.05) NAR levels (1.6 vs. 2.3) (p < 0.05) were significantly higher in group 2. CONCLUSIONS: NAR can be used in predicting the stage of NSCLC.

Laboratory evidence on a direct correlation between acute central serous chorioretinopathy and tenascin C, metalloprotein 1, BAX, BCL2, subfatin and asprosin.

PURPOSE: Central serous chorioretinopathy (CSCR) is an eye disease of unknown etiology that presents with reduced visual acuity, choroidal thickening (distance between Bruch's membrane and the chorioscleral border), and subretinal fluid leakage. In the present study, the goal was to investigate the role of the interrelated tenascin C, metalloprotein-1, BAX, BCL2, subfatin and asprosin molecules in the pathogenesis of CSCR. METHOD: Thirty CSCR patients and 30 controls were included. CSCR was diagnosed by optical coherence tomography imaging. A 5mL blood sample was collected from all participants after overnight fasting. Compounds in the blood samples were studied with the Enzyme-Linked Immunosorbent Assay (ELISA) method. RESULTS: Patients with CSCR were found to have macular thickening (P: 0.08) and statistically significantly reduced visual acuity (P: 0.034) compared to controls. With regard to serum parameters, there were statistically significant increases in tenascin C, metalloprotein-1, BAX, BCL2, subfatin and asprosin levels compared to controls. We found a positive correlation between macular thickness and tenascin C (r+0.670, P<0.001), metaloprotein-1 (r+0.714, P<0.001), BAX, BCL2 (r+0.771, P<0.001), subfatin and asprosin levels and a negative correlation between visual acuity and tenascin C (r+0.605 P<0.001), metaloprotein-1 (r+0.704, P<0.001), BAX, BCL2 (r+0.738, P<0.001), subfatin and asprosin levels. CONCLUSION: The molecules studied herein were negatively correlated with visual acuity and positively correlated with macular thickness, suggesting that these molecules might have a role in the pathogenesis of CSCR. Thus, we predict that these molecules could be new candidates for the diagnosis and follow-up of CSCR in the future.

The effect of the COVID-19 pandemic lockdown on symptom severity in school children with house dust mite-sensitized allergic rhinitis.

Study objective: The lockdown imposed on children due to the COVID-19 pandemic and their inability to attend school increased their exposure to indoor allergens by causing them to spend more time indoors. In this study, the aim was to reveal the effect of the pandemic and increased exposure to indoor aeroallergens on the symptom severity of school-age children with house dust mite-sensitized allergic rhinitis (AR). Patients and methods: Patients between the ages of 6-18-years old, who were followed-up with the diagnosis of perennial AR sensitized to only mites were questioned about their sinonasal symptoms. The Total Nasal Symptom Score (TNSS) questionnaire was performed. The clinical findings, drug usage, frequency of infections and attacks were evaluated and compared during COVID-19 lockdown and the same time frame in 2019. Results: Sixty-five patients had AR, and 33 patients (50.8%) had AR with asthma. TNSS of the patients improved during the pandemic (P < 0.001) and their medication scores decreased significantly (P < 0.001). The frequency of respiratory tract infections and asthma attacks decreased significantly (P < 0.001). In multivariate analysis, risk factors were evaluated for the 'group with worsening TNSS' and coal/wood burning was detected to be an independent risk factor (P = 0.006; OR = 10.09 (95% CI: 1.97-51.87)). Conclusion: Although the increased stay at home, it is surprising that nasal symptoms improved in our patients. This result suggests that whereas allergen sensitivity is responsible for the pathogenesis of AR, exposure to pollution and viral infections which are reduced by masking and social distance may also play an important role in the pathogenesis.

Introduction: Le confinement imposé aux enfants en raison de la pandémie de COVID-19, l'impossibilité pour les enfants d'aller à l'école; ont augmenté leur exposition aux allergènes intérieurs en les obligeant à passer plus de temps à l'intérieur. Dans cette étude, il visait à révéler l'effet de la période pandémique et de l'exposition accrue aux aéroallergènes intérieurs sur la sévérité des symptômes des enfants d'âge scolaire atteints de rhinite allergique (RA) sensibilisée aux acariens. Méthode: Patients âgés de 6 à 18 ans, qui ont été suivis avec le diagnostic de RA perannuelle avec seulement des acariens sensibilisés; ont été interrogés sur leurs symptômes naso-sinusiens. Le questionnaire Total Nasal Symptom Score (TNSS) a été réalisé. Leurs résultats cliniques, l'utilisation de médicaments, la fréquence des infections et des attaques ont été évalués et comparés pendant le verrouillage de COVID-19 et la même période de 2019. Résultats: Soixante-cinq patients avaient une RA et 33 patients (50,8 %) avaient une RA avec asthme. Le TNSS des patients pendant la période pandémique s'est amélioré (p < 0,001) et leurs scores de médication ont diminué de manière significative (p < 0,001). La fréquence des infections des voies respiratoires et des crises d'asthme a diminué significativement (p < 0,001). En analyse multivariée, les facteurs de risque ont été évalués pour le « groupe d'aggravation du TNSS ¼, la combustion de charbon/bois a été détectée comme étant un facteur de risque indépendant (p = 0,006 ; OR = 10,09 (IC95 % : 1,97­51,87)). Conclusion: Malgré l'augmentation du séjour à domicile, il est surprenant que les symptômes nasaux de nos patients se soient améliorés. Ce résultat suggère que si la sensibilité aux allergènes est responsable de la pathogenèse de la RA, l'exposition à la pollution et aux infections virales qui sont réduites par le masque et la distance sociale peuvent également jouer un rôle important dans la pathogenèse.

Plasma cerebellin levels in patients with central serous chorioretinopathy.

PURPOSE: To evaluate levels of plasma cerebellin, cortisol, adrenaline and noradrenaline in patients with central serous chorioretinopathy (CSC). MATERIALS AND METHODS: This prospective study included 30 patients diagnosed with acute CSC (Group 1) and a control group of 30 age-matched, healthy subjects without CSC (Group 2). Levels of plasma cerebellin, cortisol, adrenaline and noradrenaline were examined in blood samples taken after 8-12hours of fasting. A value of p<0.05 was considered statistically significant in the comparative analyses. RESULTS: The mean plasma cerebellin level was found to be 232.56±113.28 pg/ml in Group 1 and 174.07±82.04 pg/ml in Group 2 (p=0.02). Mean plasma cortisol was 13.19±3.87µg/ml in Group 1 and 9.55±2.92µg/ml in Group 2 (p<0.01). Mean plasma adrenaline was 60.62±26.67 pg/ml in Group 1 and 46.17±19.20 pg/ml in Group 2 (p=0.03). Mean plasma noradrenaline was 206.66±73.90 pg/ml in Group 1 and 149.96±51.36 pg/ml in Group 2 (p<0.01). CONCLUSION: It can be concluded that increased cerebellin may have a role in the etiology of CSC by increasing catecholamine expression from the adrenal medulla and indirectly by increasing cortisol levels via a paracrine effect from the adrenal cortex.

Seroepizootiological investigation on Goat Warble Fly Infestation (Przhevalskiana silenus) in Pothwar Plateau, Pakistan.

Goat Warble Fly Infestation (GWFI) is also known as subcutaneous myiasis caused by Przhevalskiana silenus (Diptera: Oestridae). It is widely distributed in tropical and sub-tropical areas of the world. In goats, WFI is usually detected through conventional procedure which underestimated the infestation. The current study was designed to determine the serodiagonsis of GWFI (through IDEXX Hypodermosis serum antibody test) and also aimed to investigate its seroepizootiological profile in Pothwar region, Pakistan from 2013-14. The results showed that average seropositivity (ELISA kit) of GWFI was 18.5% whereas, it was 11% by using conventional procedure (Palpation method) depicting a significant difference (p<0.05). Higher seropositivity (30.8%) was observed in Jhelum district as compared to e Attock district (6%). The L1 larvae were found in September, while nodules start appearing in October to December and last until the end of February. The month wise peaks of optical density (OD) was higher in December which gradually decrease along with the end of winter season. The prevalence of GWFI revealed no significant difference among three host breeds (Jattal, Beetal and Tedy). According to the results, high infestation rate (28%) was observed in young animals of age group < 1 year as compared to old animals (> 2 years). Topographically, hilly areas (33%) provide favourable climatic conditions for the propagating of larval stages. Sex difference showed no significant difference. The seroprevalence varied significantly with respect to age, month, districts and topographical location. The current study proved that serologic diagnosis (commercial ELISA kit) as more sensitive and accurate for timely diagnosis of GWFI than traditional method. The information on the epizootiology of P. silenus in goats of Pothwar region would help in devising effective control strategies.

Evaluation of ureteral jet dynamics in pediatric kidney stone formers: A cross-sectional study.

INTRODUCTION: The risk of kidney stone formation increases with urinary stasis, which is associated with decreased peristaltism. The relationship between nonobstructive kidney stone formation and ureteral jet dynamics, which can be measured with Doppler ultrasonography (US) and provide information about ureteral peristaltism, has been demonstrated in adults. OBJECTIVE: To investigate the relationship between ureteral jet dynamics, which provide information about ureteral peristaltism, and stone formation in children. STUDY DESIGN: Children admitted to Dokuz Eylul University Hospital with flank pain, and asymptomatic age-matched children for the control group, were prospectively enrolled and underwent Doppler US for diagnostic reasons and bilateral ureteral jet flow measurements. Children diagnosed with unilateral nonobstructive lower pole kidney stones formed Group 1, and the control group, without any evidence of stone disease, formed Group 2. Ureteral jet dynamics were compared between the affected renal units in Group 1, and healthy renal units in Group 1 and Group 2. RESULTS: A total of 32 children were included for each group. The mean average jet flow-rate (JETave (cm/second)) in affected renal units in Group 1 was found to be significantly lower than in the healthy renal units in Group 1 and left and right healthy renal units in Group 2 (P < 0.05). The continuous JETpattern rate in affected renal units in Group 1 was found to be significantly higher compared with healthy renal units in Groups 1 and 2 (P = 0.012) (Table). The odds ratio for kidney stone formation was 5.6 for renal units with JETave <9.5 cm/s when compared with renal units with JETave ≥9.5 cm/s. DISCUSSION: In a recent study, it was demonstrated in adults that low ureteral jet flow-rate and continuous JETpattern were significantly higher in affected renal units. The findings in children were also similar to adults: the mean JETave was significantly lower and determination rate of continuous flow pattern was significantly higher in affected renal units. CONCLUSIONS: Children with low JETave and continuous JETpattern as a sign of decreased ureteral peristaltism are at an increased risk of kidney stone formation. However, it is vital that further studies are conducted to elaborate on this topic.

Depression in dialysis patients.

Many psychiatric disorders can be seen in patients with chronic renal failure (CRF). Haemodialysis (HD), which is a renal replacement treatment, causes various psychiatric and psychosocial problems. Patients are dependent on treatment and the illness causes various problems. In addition, strict diet and continuous treatment are other stress factors (1,2). Various studies have been published in different regions and countries about the prevalence of depression and the relation between sociodemographic factors and depression in patients treated by continuous ambulatory peritoneal dialysis (CAPD), which has gradually become common in Turkey. However studies, which reflect the authors' region, have become necessary (2,3).

Massive lower gastrointestinal bleeding in typhoid fever.

Typhoid fever is an infectious disease that is usually treated medically and rarely needs surgical intervention. In this paper, we report three cases of severe colonic involvement in salmonella infection in patients traveling in or coming from endemic areas, resulting in ulceration and massive anorectal bleeding.
