RESUMEN
OBJECTIVE: Cervical Inlet Patch (CIP) is an interesting entity that is little known and often neglected by endoscopists. It has always been reported as less than expected. In this article, for the first time in the literature, we want to measure the true prevalence of CIP in a center dealing with specific esophageal diseases. PATIENTS AND METHODS: From October 2020 to October 2021, a total of 283 patients, aged 15-95 years, with mainly dyspeptic and reflux-like complaints were included in this study. All endoscopic procedures were performed carefully by a single endoscopist. Patients were examined for any possible presence of CIP, with adequate sedation and time. RESULTS: The prevalence of CIP, which was the primary aim of our study, was detected at a rate of 14.8%. Most CIP was observed as a single lesion (73.8%), and many of them (45.2%) were larger than 10 mm. Plenty of patients had upper endoscopy due to dyspeptic complaints, but only 2.5% of them presented with a preliminary diagnosis of laryngeal reflux. CONCLUSIONS: The true CIP prevalence is higher than reported before. Our result is the highest prevalence rate of CIP was detected in Turkey. In this regard, data coming from centers dealing with specific esophageal diseases may be more reliable and true.

OBJECTIVE: Insulin resistance is an important risk factor for developing metabolic syndromes that cause morbidity diseases such as diabetes and cardiovascular diseases. Interestingly, in chronic inflammatory diseases, some inflammatory mediators can play, either directly or indirectly, a pivot role in the development of insulin resistance. This can be considered as an additional factor causing increased mortality and morbidity in these patients. In this paper, we want to investigate and compare the insulin resistance status in patients with Inflammatory Bowel Disease (IBD) and healthy control, as well as different stages of patients with Ulcerative colitis (UC) and Crohn's Disease (CD). PATIENTS AND METHODS: A total of 180 patients were enrolled in this study; while 95 patients had inflammatory bowel disease [Crohn's Disease (n): 47, Ulcerative colitis (n): 48], 85 people were healthy controls. Insulin resistance status was evaluated with the HOMA-IR (hemostasis model of assessment of insulin resistance) index. p < 0.05 was accepted as significant. RESULTS: The mean HOMA-IR levels were found to be similar for both IBD and control, and Crohn's disease and control (p = 0.174, p = 0.96, respectively); but the mean HOMA-IR score in ulcerative colitis, one of the IBD subgroups, was significantly higher than the control group (p < 0.039). CONCLUSIONS: This study clearly showed that insulin resistance is increased in ulcerative colitis. Consequently, patients with ulcerative colitis should be followed and closely monitored for developing insulin resistance, metabolic syndromes, diabetes, and cardiovascular diseases. Consequently, all of them can cause an additional risk of morbidity and mortality in these patients.

OBJECTIVE: Primary epiploic appendagitis (PEA) is a rare cause of abdominal pain revealed by torsion of colonic structures called epiploic appendices. In this paper, we present our clinical data and experience regarding this rare condition that may be confused with many diseases, such as acute appendicitis, diverticulitis, salphingitis, renal colic that may require emergency surgery. MATERIALS AND METHODS: A total of 39 consecutive patients diagnosed as PEA confirmed by abdominal computed tomography with a clinical course. Basic demographic data, abdominal pain characteristics, physical examination findings, laboratory results, treatment methods, and clinical course of the patients were retrospectively evaluated. Statistical analysis was performed using SPSS (18.0; Chicago, IL, USA), using the χ2-test and Fisher's exact test. RESULTS: Of the 39 patients diagnosed with PEA, 35 were male and 4 were female; the mean age of the patients was 36.0 ± 10.3. The main complaints were 69.2% abdominal pain, 12.8% groin pain, 5.1% flank pain with nausea and vomiting (2.6%), and abdominal swelling and dysuria. The average time of symptom was 5.3 days (1-15 days). In the computed tomography scan images, PEA was located in the sigmoid colon (21, 53.8%), descending colon (10, 25.6%), ascending colon (5, 12.8%), cecum (2, 5.1%), and hepatic flexure (1, 2.6%). No patient underwent surgical treatment. However, 9 of 39 patients were hospitalized for medical treatments, such as antibiotics and analgesic drugs intravenously. All patients were followed-up for a period of 1-year and there were no recurrence symptoms. CONCLUSIONS: When patients with localized lower abdominal pain and tenderness do not have associated symptoms or laboratory abnormalities, a high index of suspicion for PEA and early radiologic examinations are required.

An association panel consisting of 185 accessions representative of the barley germplasm cultivated in the Mediterranean basin was used to localise quantitative trait loci (QTL) controlling grain yield and yield related traits. The germplasm set was genotyped with 1,536 SNP markers and tested for associations with phenotypic data gathered over 2 years for a total of 24 year × location combinations under a broad range of environmental conditions. Analysis of multi-environmental trial (MET) data by fitting a mixed model with kinship estimates detected from two to seven QTL for the major components of yield including 1000 kernel weight, grains per spike and spikes per m(2), as well as heading date, harvest index and plant height. Several of the associations involved SNPs tightly linked to known major genes determining spike morphology in barley (vrs1 and int-c). Similarly, the largest QTL for heading date co-locates with SNPs linked with eam6, a major locus for heading date in barley for autumn sown conditions. Co-localization of several QTL related to yield components traits suggest that major developmental loci may be linked to most of the associations. This study highlights the potential of association genetics to identify genetic variants controlling complex traits.

Population structure and genome-wide linkage disequilibrium (LD) were investigated in 192 Hordeum vulgare accessions providing a comprehensive coverage of past and present barley breeding in the Mediterranean basin, using 50 nuclear microsatellite and 1,130 DArT((R)) markers. Both clustering and principal coordinate analyses clearly sub-divided the sample into five distinct groups centred on key ancestors and regions of origin of the germplasm. For given genetic distances, large variation in LD values was observed, ranging from closely linked markers completely at equilibrium to marker pairs at 50 cM separation still showing significant LD. Mean LD values across the whole population sample decayed below r (2) of 0.15 after 3.2 cM. By assaying 1,130 genome-wide DArT((R)) markers, we demonstrated that, after accounting for population substructure, current genome coverage of 1 marker per 1.5 cM except for chromosome 4H with 1 marker per 3.62 cM is sufficient for whole genome association scans. We show, by identifying associations with powdery mildew that map in genomic regions known to have resistance loci, that associations can be detected in strongly stratified samples provided population structure is effectively controlled in the analysis. The population we describe is, therefore, shown to be a valuable resource, which can be used in basic and applied research in barley.

The aim of the study was to determine the chromium concentrations of soil and plant specimens taken from a rural area exposed to cement factory emissions and also to determine the blood concentrations and sensitivity conditions observed in humans residing in this rural area. The study was carried out in Cukurhisar, a town in Eskisehir-Turkey, between May 2000 and March 2001. Besides the 108 soil (36 for control) and plant specimens, which were taken from eight different directions from the cement factory, blood samples of the individuals residing in this area were taken from 258 subjects (258 for control) following a physical examination, and patch tests were also applied. The chromium concentrations of the soil and plant specimens taken from different places in different directions of the factory were higher than in the control areas. The physical examination of subjects did not reveal results different from those of the control group except for the diagnosis of contact dermatitis. The analyses of venous blood samples showed that chromium concentrations were found to be within the reference values given for both groups, but higher in the subjects (P<0.001). According to the results of patch tests, sensitivity to chromium was found to be more frequent for the subject group than the control group (P<0.05). According to these results, clinical tools revealed no toxic effects for the subjects, except contact dermatitis. However, sensitivity to patch tests showed that this subject group has been affected compared to the control group and that this effect increased with age.
