Benign biliary strictures associated with acute biliary pancreatitis.

BACKGROUND AND AIMS: There are limited data about the benign biliary strictures (BBS) which can develop during the clinical course of acute biliary pancreatitis (ABP) due to compression of the common bile duct (CBD) by edematous and inflamed pancreatic tissue. We aimed to determine the incidence of BBS due to ABP and its clinical course after endoscopic management. METHODS: The study was retrospectively conducted among patients with ABP who were admitted to a single tertiary reference center during 3 years. BBS-ABP was defined as distal narrowing of the CBD with proximal dilatation and delayed drainage of the contrast into the duodenum. Endoscopic treatment was performed by inserting a single 7F or 10F plastic stent which was exchanged every 3 months until stricture resolution. Patients were followed for 1 year after stricture resolution. RESULTS: Seven hundred and twenty-one patients had ABP during the study period. Among them, 257 (35.6%) patients underwent ERCP and 26 patients (3.6%) had CBD stricture due to ABP. A 7 Fr plastic stent was inserted in 18 patients and 10 Fr in 8 patients. The stricture was completely resolved at 3 months in 66.7%, at 6 months 23.8% and at 9 months (9.5%) of the patients. There was no procedure-related complications other than asymptomatic stent migration in 4 (19%) patients. None of the patients had recurrent biliary stricture during the 1 year stent-free follow-up period. CONCLUSION: BBS-ABP is a frequently seen clinical entity. In most patients, the stricture improves within 3 months and temporary endoscopic stenting prevents the patients from the consequences of the obstruction during this period.

Higher Complications During the Waiting Period for Interval Cholecystectomy in Patients With Mild Biliary Pancreatitis.

BACKGROUND: Although current guidelines recommend cholecystectomy during the same admission in patients with mild acute biliary pancreatitis (ABP), it involves a waiting list most of the time. We aimed to assess the risk of complications and determine predictors during the waiting period for cholecystectomy after the first episode of ABP. METHODS: A prospective observational study was conducted in patients with mild ABP. Follow-ups were done by phone calls or using electronic health records for a maximum of 6 months after discharge or until cholecystectomy. RESULTS: A total of 194 patients were included in the study. Although all patients were referred to surgeons, only 81 (41.8%) underwent cholecystectomy within 6 months after discharge. During the observation period, gallstone-related biliary events (GRBEs) developed in 68 (35.1%) patients, which included biliary colic, recurrent ABP, acute cholecystitis, choledocholithiasis, gallbladder perforation, cholangitis, and liver abscess. The overall readmission rate was 25.2%, with 44.8% occurred within 4 weeks after discharge. The odds ratio of any complication was 1.58 (95% CI, 1.42 to 1.76, P =0.028) and 1.59 (95% CI, 1.42 to 1.78, P =0.009) in the patients who did not have surgery within 2 to 7 days and 8 to 15 days, respectively. A 4-fold increased risk of readmission was detected (95% CI, 1.16 to 13.70, P =0.019) if cholecystectomy was not performed within 31 to 90 days. The patients who developed complications had significantly higher C-reactive protein at admission, longer waiting time, and had 3 or more gallstones on imaging. CONCLUSIONS: Interval cholecystectomy was associated with a high risk of complications during the waiting period in patients with mild ABP.

Association of mortality and endothelial dysfunction with serum ADMA level in COVID-19 patients.

Objectives: To investigate the role of asymmetric dimethylarginine (ADMA) level in predicting intensive care and mortality in patients affected with coronavirus disease 2019 (COVID-19). Methods: This retrospective, cross-sectional study was conducted at Sakarya University Training and Research Hospital (Sakarya, Turkey) between April and August of 2020. We enrolled patients who were diagnosed with COVID-19 via real-time reverse-transcription polymerase chain reaction and admitted to the intensive care (Severe COVID-19; S-COVID) or non intensive care (Moderate COVID-19; M-COVID). We then analyzed the relationship of the ADMA level with various parameters between S-COVID and M-COVID groups. Results: This study included 87 patients, comprising 43 females and 44 males, with a mean age of 61 and 71.50 years, respectively. The male/female distribution was 22/25 (46.8%/53.2%) in the M-COVID group and 22/18 (55%/45%) in the S-COVID group. The hospitalization time, white blood cell count, neutrophil count, lymphocyte-to-albumin ratio, international normalization ratio, D-dimer, troponin, ferritin, lactate dehydrogenase, C-reactive protein, procalcitonin, erythrocyte sedimentation rate, fibrinogen, lactate, ADMA, and mortality rate were significantly higher (p < 0.05). In contrast, lymphocyte, total cholesterol, high-density lipoprotein, calcium, and albumin values were lower (p < 0.05) in the S-COVID group than in the M-COVID group. While the mortality rate was 55% in S-COVID patients, no mortality was detected in M-COVID patients (p < 0.05). Moreover, ADMA level was 6618 ± 3000 (6400) in S-COVID patients and 5365 ± 3571 (3130) in M-COVID patients, indicating a statistically significant difference (p = 0.012). Conclusion: The asymmetric dimethylarginine level increases in severe outcomes; hence, it can potentially predict severity in patients with COVID-19.

The role of hematological parameters in distinguishing acute appendicitis from lymphoid hyperplasia.

BACKGROUND: One of the most misdiagnosed appendicular pathologies is lymphoid hyperplasia (LH) that can be managed con-servatively when identified early and is self-limiting. The aim of this retrospective study was to compare acute appendicitis (AA) with LH in terms of hematological parameters to determine whether there is a hematological predictor to distinguish the two diseases. METHODS: Complete blood cell counts of patients with AA were compared with those having LH. RESULTS: One-hundred-ninety-five patients (118 male/77 female) underwent appendectomy. Histopathological examination re-vealed acute AA in 161 patients (82.6%), and negative appendectomy (NA) in 19 patients (9.7%). Of the NA specimens, 16 were LH (8.2%). Thirteen patients (6.7%) had AA with simultaneous LH. White blood cell count (p=0.030, neutrophil (p=0.009), neutrophil per-centage (p=0.009), and neutrophil/lymphocyte ratio (p=0.007) were significantly higher in AA whereas lymphocyte count (p=0.027), lymphocyte percentage (p=0.006) were significantly higher in LH. Multi logistic regression analysis revealed white blood cell count as the only independent predictor in distinguishing AA from LH with a 69.1% sensitivity, 80.0% specificity, 77.5% positive predictive value, and 72.1% negative predictive value. The cut-off value for white blood cell count was 11.3 Ku/L, and every one unit (1000/mm3) increase in white blood cell count raises the risk of AA by 1.24 times, while values below this value will increase the likelihood of LH. CONCLUSION: The most predictive complete blood count parameter in distinguishing LH from AA appears to be as white blood cell count.

Hepatitis B reactivation after oral capecitabine treatment in a rectum cancer patient with isolated anti-HBc IgG positivity.

INTRODUCTION: Hepatitis B virus (HBV) reactivation in the setting of chemotherapy and immunosuppressive therapy is associated with significant morbidity and mortality. Herein we present a case of HBV reactivation after oral capecitabine treatment in a patient with rectum cancer and isolated anti-HBc IgG positivity. CASE REPORT: A 57-year-old man was consulted from the oncology clinic because of increased serum liver tests after chemotherapy. He underwent surgery for early-stage rectal cancer and received adjuvant chemotherapy with oral capecitabine. After cessation of chemotherapy, his laboratory tests revealed severe liver dysfunction. HBV markers showed positivity for hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc). HBV DNA level was markedly elevated. MANAGEMENT AND OUTCOME: A review of medical records revealed that, before chemotherapy, the patient was positive for anti-HBc IgG but negative for HBsAg, and serum aminotransferases were within the normal limits. A diagnosis of HBV-related hepatitis due to capecitabine use was made, and the patient was put on tenofovir treatment. Six months later, HBV DNA decreased, and liver function tests were normalized. DISCUSSION: To the best of our knowledge, this is the first case report describing HBV reactivation after chemotherapy with capecitabine for rectal cancer in a patient with isolated anti-HBc IgG positivity. Our case shows that HBV reactivation may develop in a low-risk patient with a low degree of immunosuppression.

The effect of short-term intensive insulin therapy in newly-diagnosed Type-2 diabetic patients.

OBJECTIVES: We aimed to determine the effect of short-term intensive insulin therapy (SIIT) on long-term glycemic control in newly-diagnosed Type-2 diabetes mellitus (nT2DM) patients. METHODS: In this retrospectively study conducted at Sakarya University Medical Faculty Training and Research Hospital Outpatient Clinic between 2016 and 2019, 65 nT2DM patients were enrolled soon after their SIIT was initiated and were followed for at least a year. Intensive insulin treatment was discontinued after three or 12 months in a total of 65 (23-73-year-old) patients who had been newly diagnosed with T2DM. Intensive insulin therapy was discontinued when glycemic control and the target Glycated Hemoglobin (HbA1c) level had been attained, after which oral anti-diabetic drug (OAD), long-term insulin, and diet therapies were pursued. RESULTS: There was a significant decrease in mean HbA1c from 11.25±1.96% to 6.67±1.07%. Fasting plasma glucose (FPG) was found to be an independent predictor of whether intensive insulin therapy could be discontinued after three months in a model that included FPG, HbA1c, and body mass index measured at baseline. Patients with FPG>13.8 mmol/L were 7.6 times more likely to require intensive insulin therapy beyond three months. There were significant decreases in HbA1c and low-density lipoprotein-cholesterol concentration, but no change in C-peptide between baseline and 3 months of therapy. CONCLUSION: These results demonstrate that in nT2DM patients, intensive insulin therapy could be effective on long-term glycemic control and high FPG prior to three months of SIIT may predict poor long-term glycemic control.

A Simple Method for Endoscopic Treatment of Large Gastric Phytobezoars: "Hand-Made Bezoaratome".

BACKGROUND: Large gastric phytobezoars are generally resistant to standard chemical or endoscopic treatments. We presented our experience of an alternative endoscopic method using a hand-made tool called a "hand-made bezoaratome" for the treatment of large gastric phytobezoars. METHODS: Patients who consulted or who were diagnosed with gastric bezoars at an education and research hospital between January 2015 and December 2018 were prospectively included in the study. Patients with phytobezoars of 50 mm and larger were included in the study. Patients with trichobezoars, lactobezoars, pharmacobezoars, under 18 years of age, and pregnant women were excluded. A 0.25 mm diameter guidewire and a mechanical lithotripter sheath were used to prepare the "hand-made bezoaratome." After the first procedure, patients were advised to consume 2500 mL of Coca Cola® or the same amount of pineapple juice per day, until the next procedure. Endoscopic procedures were performed at 5-day intervals until complete reabsorption of the bezoar was achieved. Patients were followed up for 6 weeks. RESULTS: The study group included 37 (21 males, mean age: 57.6 ± 12.5 years) patients. The median size of the phytobezoars was 71 mm (50-90). The median endoscopic procedure time was 853 s (380-1940 s). The success rate for endoscopic fragmentation was found to be 100%. No major complications occurred during the endoscopic procedures, but 1 patient (2.7%) required surgery for ileus due to an obstruction at the distal part of the jejunum, 61 h after the second endoscopic session. The overall success rate of the endoscopic treatment was 97.3%. CONCLUSION: Using a "hand-made bezoaratome" is effective and reliable for the endoscopic treatment of large gastric bezoars.

Comparative evaluation of memory T cells in COVID-19 patients and the predictive role of CD4+CD8+ double positive T lymphocytes as a new marker.

BACKGROUND: The COVID-19 pandemic has affected the entire world, posing a serious threat to human health. T cells play a critical role in the cellular immune response against viral infections. We aimed to reveal the relationship between T cell subsets and disease severity. METHODS: 40 COVID-19 patients were randomly recruited in this cross-sectional study. All cases were confirmed by quantitative RT-PCR. Patients were divided into two equivalent groups, one severe and one nonsevere. Clinical, laboratory and flow cytometric data were obtained from both clinical groups and compared. RESULTS: Lymphocyte subsets, CD4+ and CD8+ T cells, memory CD4+ T cells, memory CD8+ T cells, naive CD4+ T cells, effector memory CD4+ T cells, central memory CD4+ T cells, and CD3+CD4+ CD25+ T cells were significantly lower in severe patients. The naive T cell/CD4 + EM T cell ratio, which is an indicator of the differentiation from naive T cells to memory cells, was relatively reduced in severe disease. Peripheral CD4+CD8+ double-positive T cells were notably lower in severe presentations of the disease (median DP T cells 11.12 µL vs 1.95 µL; p< 0.001). CONCLUSIONS: As disease severity increases in COVID-19 infection, the number of T cell subsets decreases significantly. Suppression of differentiation from naive T cells to effector memory T cells is the result of severe impairment in adaptive immune functions. Peripheral CD4+CD8+ double-positive T cells were significantly reduced in severe disease presentations and may be a useful marker to predict disease severity.

Correlation of Lung Ultrasound and Computed Tomography Findings in COVID-19 Pneumonia.

OBJECTIVE: To evaluate the laboratory confirmed COVID-19 pneumonia and correlate the findings obtained by thorax ultrasound (USG) and thorax computed tomography (CT). STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Departments of Infection Disease, Internal Medicine and Radiology, Sakarya Training and Research Hospital, Sakarya, Turkey, between March and May 2020. METHODOLOGY: This study was consisted of 100 adult patients having rRT-PCR positive COVID-19 pneumonia diagnossed by thorax CT. The clinical features, thorax USG and CT findings of these patients were recorded and expressed. USG and thorax CT findings were scored using a method described before. Continuous variables were expressed as mean (±SD) values. The Kolmogorov-Smirnov test was used for the normal distribution test, and continuous variables were compared using the Mann-Whitney U test.  USG and CT performed at time of admission to the hospital. Descriptive statistics were conducted based on the structures of variable. RESULTS: A total of 100 patients (54 men and 46 women; mean age, 59.88±13.03 years; range, 28-91years) with COVID-19 pneumonia were evaluated. Involvement areas on the lower posterior of the right side were detected as 70% by ultrasound and 74% by CT. Positively correlation was detected in lung scans assessed by USG and CT (p<0.001, r=0.705). CONCLUSION: Ultrasound has several advantages including no ionizing radiation exposure for health care workers, being a safe, fast and non-invasive diagnostic technique with bedside usage. Hence, ultrasound is an efficient alternative to diagnosis and monitor of patients with COVID-19 pneumonia. Key Words: COVID-19, Lung ultrasound, Pneumonia, RRT-PCR.

RESUMO OBJETIVO: A pandemia de COVID-19 tem afetado o mundo todo, constituindo uma ameaça grave para a saúde humana. As células T desempenham um papel crítico na imunidade celular contra infecções virais. Procuramos desvendar a relação entre sub grupos de células T e a severidade da doença. MÉTODOS: Um total de 40 pacientes com COVID-19 foram aleatoriamente recrutados para o presente estudo transversal. Todos os casos foram confirmados por RT-PCR quantitativo. Os pacientes foram divididos em dois grupos equivalentes, um grave e um não-grave. Os dados da avaliação clínica, laboratorial e da citometria de fluxo foram obtidos para ambos os grupos e comparados. RESULTADOS: Os subconjuntos de linfócitos, células T CD4+ e CD8+, células T de memória CD4+, células T de memória CD8+, células T CD4+ virgens, células T efetoras CD4+, células T de memória central CD4+ e células T CD3+ CD4+ CD25+ estavam significativamente mais baixas nos pacientes graves. A razão células T virgens/células T efetoras TCD4+, que é um indicador da diferenciação entre células T virgens e células de memória, estava relativamente reduzida em casos graves da doença. As células T duplo-positivas CD4+CD8+ periféricas estavam notavelmente mais baixas em casos graves da doença (mediana das células T DP: 11,12 µL vs. 1,95 µL; p< 0,001). CONCLUSÃO: Conforme aumenta a gravidade da doença nos casos de COVID-19, o número de subconjuntos de células T diminui significativamente. A supressão da diferenciação de células T virgens para células T efetoras é o resultado do comprometimento grave das funções imunológicas adaptativas. As células T duplo-positivas CD4+CD8+ periféricas estavam notavelmente mais baixas em casos graves da doença e podem ser um marcador útil para predizer a severidade da doença.

The Importance of Eosinopenia for Predicting Treatment Response in Patients with Cholangitis.

OBJECTIVE: To compare recovery of eosinopenia, C-reactive protein (CRP) and procalcitonin levels in predicting the response to treatment in patients with cholangitis. STUDY DESIGN: Descriptive, analytical study. PLACE AND DURATION OF STUDY: Department of Gastroenterology, Sakarya Training and Research Hospital, Turkey between September 2018 and February 2019. METHODOLOGY:  Patients with cholangitis, who underwent endoscopic retrograde cholangiopancreatography (ERCP), were inducted. Those with choledocholic thiasis alone were considered controls. Eosinophil count above 100.5 cells/µL was the limit value accepted as improvement. ERCP repeat was decided according to eosinophil count below 100.5 and not clinically improving. Relationship between inflammatory markers such as CRP, procalcitonin and eosinopenia values in patients with stone-associated cholangitis was investigated. RESULTS: The cholangitis group was comprised of 62 patients [mean age 67±14.57 years; 26 (41.9%) female], while control group was comprised  of 57 patients [mean age 57.4±18.10 years; 39 (68.4%) females, p=0.004]. At time of admission, median eosinophils was significantly lower in cholangitis group at 17.50 [9.82-84] ×103/µL compared to control group at 168 [100.11-270] ×103/µL (p=0.001). ERCP were repeated on two patients as their clinical conditions and unremitting eosinophil counts worsened. Eosinophil and CRP markers and clinical improvement were observed after  second ERCP procedure. CONCLUSION: Eosinopenia may be used as inflammatory marker in  evaluation of response to treatment and for predicting the need to repeat ERCP during clinical follow-up of patients who undergo cholangitis treatment. Key Words: Cholangitis, C-reactive protein, Endoscopic retrograde cholangiopancreatography, Eosinopenia, Procalcitonin.

Neutrophil count to albumin ratio as a new predictor of mortality in patients with COVID-19 infection.

BACKGROUND: Coronavirus Disease 2019 is an acute inflammatory respiratory disease. It causes many changes in hemogram parameters. Low albumin levels are associated with mortality risk in hospitalized patients. The aim of the present study is to reveal the place of neutrophil count to albumin ratio in predicting mortality in patients with COVID-19. METHODS: 144 patients, 65 females and 79 males, were included in the study. Patients were divided into 2 groups. Group 1 was the non-severe group (n:85), and Group 2 was severe (n:59). Demographic data, neutrophil, lymphocyte and platelet counts, albumin and C-reactive protein (CRP) levels were recorded. Neutrophil count to albumin ratio (NAR) was calculated by dividing the absolute neutrophil counts by the albumin levels. The NAR and levels of the two groups were then compared. RESULTS: There were no significant differences in gender and platelet count (201 vs. 211 K/mL) between the groups (p>0,05). Ages (62.0 ± 14.3 vs 68.6 ± 12.2 years), albumin (33.1 vs 29.9 gr/L), CRP (33 vs 113 mg/l), neutrophil count (4 vs 7.24 K/mL), WBC counts (6.70 vs 8.50 K/mL), NAR values (113.5 vs 267.2) and number of Death (5 vs 33) were found to be statistically higher (p <0.001) in Group 2 than in Group 1. The NAR value of 201.5 showed mortality in all patients with COVID-19 to have 71.1% sensitivity and 71.7% specificity (AUC:0.736, 95% CI: 0.641-0.832, p<0.001). CONCLUSION: The present study showed that NAR levels can be a cheap and simple marker for predicting mortality in patients with COVID-19.

Reliability and Validity of the Turkish Version of the Glasgow-Edinburgh Throat Scale: Use for a Symptom Scale of Globus Sensation in Turkish Population.

OBJECTIVE: In this study, we aimed to translate the Glasgow-Edinburgh Throat Scale (GETS) into Turkish and test its reliability and validity. METHODS: A total of 69 patients with globus sensation and no signs of otolaryngologic or gastroenterological disease in etiology were included in the study. The patients were asked to complete the translated Turkish version (GETS-T) of GETS and the Hospital Anxiety and Depression Scale (HADS). RESULTS: The Cronbach's alpha coefficient of the patients in the study group was calculated based on the 12 questions in the GETS-T scale and found as 0.868. The correlation between the GETS-T total score and the total HADS score in the study group was found to be very low and statistically insignificant. As a result of factor analysis, it was found that the first 10 problems in GETS-T were divided into two sub-groups, unlike GETS. CONCLUSION: Translation of GETS into Turkish (GETS-T) showed high reliability and validity, suggesting that translation and cross-cultural adaptation was appropriate. The GETS-T can be used in studies about globus pharyngeus in future.

RESUMO ANTECEDENTES A doença de coronavírus 2019 é uma doença respiratória inflamatória aguda. Causa muitas alterações nos parâmetros do hemograma. Baixos níveis de albumina estão associados ao risco de mortalidade em pacientes hospitalizados. O objetivo do presente estudo é revelar o local da razão entre contagem de neutrófilos e albumina na predição de mortalidade em pacientes com COVID-19. MÉTODOS Cento e quarenta e quatro pacientes do sexo feminino e 79 do sexo masculino foram incluídos no estudo. Os pacientes foram divididos em dois grupos: Grupo 1 não grave (n: 85), Grupo 2 grave (n: 59). Dados demográficos, contagem de neutrófilos, linfócitos e plaquetas, níveis de albumina e proteína C reativa (PCR) foram registrados. A razão de contagem de neutrófilos para albumina (NAR) foi calculada dividindo-se as contagens absolutas de neutrófilos pelos níveis de albumina. O NAR e os níveis dos dois grupos foram comparados. RESULTADOS Não houve diferenças significativas no sexo e na contagem de plaquetas (201 vs 211 K/mL) entre os grupos (p>0,05). Idade (62,0±14,3 vs 68,6±12,2 anos), albumina (33,1 vs 29,9 gr/L), PCR (33 vs 113 mg/l), contagem de neutrófilos (4 vs 7,24 K/mL), contagem de leucócitos (6,70 vs 8,50 K/mL), valores de NAR (113,5 vs 267,2) e número de óbitos (5 vs 33) foram estatisticamente maiores (p<0,001) no Grupo 2 que no Grupo 1. O valor NAR de 201,5 mostrou mortalidade em todos os pacientes com COVID-19 com sensibilidade de 71,1% e especificidade de 71,7% (AUC: 0,736, IC 95%: 0,641-0,832, p<0,001). CONCLUSÃO O presente estudo mostrou que os níveis de NAR podem ser um marcador barato e simples para predizer mortalidade em pacientes com COVID-19.

Comparison of monopolar hemostatic forceps with soft coagulation versus hemoclip for peptic ulcer bleeding: a randomized trial (with video).

BACKGROUND AND AIMS: Although various methods are used in the treatment of peptic ulcer bleeding, there is not a standard recommended approach. The choice depends on multiple factors such as location of the ulcer, clinical experience of the endoscopist, and local facilities of the clinic. We aimed to compare the efficacy of monopolar hemostatic forceps soft coagulation (MHFSC) and hemoclips (HCs) in the treatment of peptic ulcer-related upper GI bleeding. METHODS: The study group included patients who had GI bleeding due to Forrest 1a, 1b, and 2a gastric or duodenal ulcers within 1 year. Patients with bleeding diathesis, history of gastrectomy, pregnancy, or younger than age 18 years were excluded. The remaining were randomized to MHFSC and HC treatment groups and compared in terms of clinical and endoscopic features, initial hemostasis success rates, recurrent bleeding rates within the first 7 days, time to achieve hemostasis, length of hospitalization stay, and adverse events. RESULTS: One hundred twelve patients were randomized to MHFSC (n = 56) and HC (n = 56) groups. There was no statistically significant difference between the groups with respect to demographic features, medications, underlying chronic diseases, location, and Forrest classification of the ulcers. The initial hemostasis success rate was 98.2% (55/56) in the MHFSC group and 80.4% (45/56) in the HC group (P = .004). Recurrent bleeding was detected in 2 patients in the MHFSC group (3.6%) and 8 patients in the HC group (17.7%; P = .04). The duration of endoscopic procedures (302 ± 87.8 vs 568 ± 140.4 seconds) and the length of hospital stay (3.50 ± 1.03 vs 4.37 ± 1.86 days) were significantly shorter in the MHFSC group. There were no adverse events in either group. CONCLUSIONS: MHFSC is more effective in achieving initial hemostasis compared with HCs in the treatment of peptic ulcer bleeding and provides a shorter procedure time and a lower recurrent bleeding rate.

Similar subclinical enthesitis in celiac and inflammatory bowel diseases by ultrasound suggests a gut enthesis axis independent of spondyloarthropathy spectrum.

Objective: Higher subclinical enthesitis on US has been reported in IBD and celiac disease, separately. The objective of this study was to compare IBD and celiac disease for enthesitis on US. Higher enthesitis scores in IBD compared with celiac disease would support a shared pathogenic mechanism between IBD and spondyloarthritis, whereas similar scores may suggest a general impact of gut inflammation on the enthesis. Methods: Patients with IBD, celiac disease and healthy controls (HCs) were recruited and 12 entheses were scanned by US, blind to the diagnosis and clinical assessment. Elementary lesions for enthesitis were scored on a scale between 0 and 3, for inflammation, damage and total US scores. Results: A total of 1260 entheses were scanned in 44 patients with celiac disease, 43 patients with IBD and 18 HCs. The three groups were matched for age and BMI. Patients with celiac disease and IBD had higher inflammation scores than HCs [10.4 (6.5), 9.6 (5.4) and 5.6 (5.2), respectively, P = 0.007) whereas damage scores were similar. Both age and BMI had significant effects on the entheseal scores, mostly for inflammation scores but when controlling for these the US enthesopathy scores were still higher in celiac disease and IBD. Conclusion: The magnitude of subclinical enthesopathy scores is similar between celiac disease and IBD in comparison with HCs. These findings suggest that the common factor between both diseases and enthesopathy is abnormal gut permeability, which may be modified by the genetic architecture of IBD leading to clinical arthropathy.

Relationship between the target dose for hemodialysis adequacy and nutritional assessment.

BACKGROUND: Some studies have shown an increased relative risk of death for patients with higher levels of Kt/V, which may be associated with marked malnutrition. OBJECTIVE: The aim of this study was to investigate the relationship between the target dose for hemodialysis adequacy, as measured by Kt/V, and various nutritional parameters in hemodialysis patients. DESIGN: Cross-sectional. SETTINGS: Sakarya University Faculty of Medicine, Turkey between February 2014 and March 2014. PATIENTS AND METHODS: For consecutive patients who met criteria, the following were recorded: nutritional status, dialysis malnutrition score (DMS), the geriatric nutritional risk index (GNRI), serum albumin level, anthropometric measurements, and bioelectrical impedance analysis. Patients were classified into two groups according to the target hemodialysis dose for single-pool Kt/V: patients with spKt/V >=1.4 and patients with spKt/V < 1.4. MAIN OUTCOME MEASURE(S): Association of hemodialysis adequacy by nutritional assessment. RESULTS: The prevalence of malnutrition in 286 patients with target dose hemodialysis (spKt/V >=1.4) was significantly higher according to body mass index (BMI), DMS, and GDRI (P=.001, P=.006, and P=.004, respectively) compared with patients with a lower target dose (spKt/V < 1.4). BMI, biceps skinfolds, mid-arm circumference, calf circumference, fat free mass, and total body water were statistically significantly lower in patients at a higher target dose (spKt/V >= 1.4) (P < .001, P=.034, P=.010, P < .001, P < .001, and P < .001 respectively). CONCLUSIONS: Malnutrition was more frequent in chronic hemodialysis patients who received the target hemodialysis. Evaluation of nutritional status in patients at the target hemodialysis dose should be considered. LIMITATIONS: Data collected from a single region; small sample size; cross-sectional design is disadvantageous.

Severe Hypokalaemia, Hypertension, and Intestinal Perforation in Ectopic Adrenocorticotropic Hormone Syndrome.

Ectopic adrenocorticotropic hormone (ACTH) syndrome is a rare cause of the Cushing's syndrome. The occurrence of the ectopic ACTH syndrome presenting with severe hypokalaemia, metabolic alkalosis, and hypertension has been highlighted in case reports. However, presentation with lower gastrointestinal perforation is not known. We report the case of a 70-year-old male patient with severe hypokalaemia, metabolic alkalosis, hypertension, and colonic perforation as manifestations of an ACTH-secreting small cell lung carcinoma. Ectopic ACTH syndrome should be kept in mind as a cause of hypokalaemia, hypertension, and intestinal perforation in patients with lung carcinoma.

Midkine in vitamin D deficiency and its association with anti-Saccharomyces cerevisiae antibodies.

OBJECTIVES AND DESIGN: The growth factor midkine (MK) is a protein that is involved in cancer, inflammation, immunity. Vitamin D is a potent immunomodulator. Anti-Saccharomyces cerevisiae antibody (ASCA) is reported in autoimmune disorders, some of which are among the causes of vitamin D deficiency. The objective of this study was to investigate a possible association of MK and ASCA with vitamin D deficiency. MATERIALS AND METHODS: 208 adults presented to internal medicine outpatient clinic for history and physical examination has been studied. Serum biochemistry, vitamin D, MK, ASCA-IgG and -IgA, IL-1ß, IL-6, IL-8, TNF-α, PDGF, VEGF were obtained. RESULTS: Vitamin D deficiency was 74.2%. Serum MK level was significantly higher in vitamin D-deficient compared to vitamin D-sufficient individuals (1138.1 ± 262.8 vs 958.6 ± 189 pg/mL, respectively; P < 0.009). Serum MK levels were also significantly higher in both ASCA-IgG and -IgA positives compared to negatives (1318.5 ± 160.3 vs 1065.5 ± 256.1, P = 0.008 and 1347.7 ± 229.7 vs 1070.1 ± 250.9 pg/mL, P = 0.011, respectively). Vitamin D was significantly lower in ASCA positives (P = 0.044).Vitamin D showed positive correlation with IL-1ß (r 0.338, P < 0.009) and negative correlation with VEGF (r -0.366, P < 0.004). CONCLUSIONS: MK was significantly elevated in vitamin D deficiency and associated with ASCA positivity which was significantly increased in vitamin D deficiency. These findings suggested that molecular mechanism of vitamin D deficiency may be related with some inflammatory processes.

A Very Rare Presentation of Multiple Myeloma: Unilateral Raccoon Eye.

Multiple myeloma (MM), the second most common hematological malignancy, is caused by the accumulation of monoclonal plasma cells in bone marrow. It accounts for 10-15% of deaths from hematological malignancies and approximately 2% of deaths from cancer. The median age at presentation is 70 years old. The diagnosis is incidental in 30% of cases. MM is often discovered through routine blood screening with a large gap between the total protein and the albumin levels. Two thirds of patients complain of bone pain, especially lower back pain. MM could be diagnosed after a pathologic fracture occurs in one third of patients. Presentation with symptoms related to hyperviscosity, hypercalcemia and bleeding tendency could also be observed. A rare presentation of MM is peri-orbital ecchymotic lesion (raccoon eye). Here, we report a 64 years old, male patient presented with unilateral raccoon eye and high erythrocyte sedimentation rate (ESR) to internal medicine outpatient. The patient was referred to hematology outpatient and was diagnosed with multiple myeloma.
