| 1 | Unusual histopathological findings in appendectomy specimens from patients with suspected acute appendicitis显示文摘AIM: To investigate the prevalence and implications of unusual histopathological findings in appendectomy specimens from patients with suspected acute appendicitis. METHODS: The demographic and histopathological data of 1621 patients (≥ 16 years-old) who underwent appendectomy to treat an initial diagnosis of acute appendicitis between January 1999 and November 2011 were retrospectively assessed. Microscopic findings were used to classify the patients under six categories: appendix vermiformis, phlegmonous appendicitis, gan- grenous appendicitis, perforated appendicitis, supurative appendicitis, and unusual histopathologic findings. The demographic and clinicopathologic characteristics of patients with unusual histopathologic findings were evaluated in detail, and re-analysis of archived resected appendix specimens was carried out. RESULTS: A total of 912 males and 709 females, from16 to 94 years old, were included in the study and comprised 789 cases of suppurative appendicitis, 370 cases of appendix vermiformis, 243 cases of perforated gangrenous appendicitis, 53 cases of flegmaneous appendicitis, 32 cases of gangrenous appendicitis, and 134 (8.3%) cases of unusual histopathological findings. The unusual histopathological findings included fibrous obliteration (n = 62), enterobius vermicularis (n = 31), eosinophilic infiltration (n = 10), mucinous cystadenoma (n = 8), carcinoid tumor (n = 6), granulomatous inflammation (n = 5), adenocarcinoma (n = 4; one of them mucinous), and mucocele (n = 3), adenomatous polyp (n = 1), taenia sup (n = 1), ascaris lumbricoides (n = 1), appendiceal diverticula (n = 1), and B cell non-hodgkin lymphoma (n = 1). None of the 11 patients with subsequent diagnosis of tumor were suspected of cancer prior to the appendectomy. CONCLUSION: Even when the macroscopic appearance of appendectomy specimens is normal, histopathological assessment will allow early diagnosis of many unusual diseases. | Mehmet Yilmaz Sami Akbulut Koray Kutluturk Nurhan Sahin Ebru Arabaci Cengiz Ara Sezai Yilmaz | 2013 | World Journal of Gastroenterology2013，19，25： | 9 |
| 2 | Adipokines and ghrelin in gastric cancer cachexia显示文摘AIM:To investigate the roles of the adipocytokines,ghrelin and leptin in gastric cancer cachexia. METHODS:Resistin,ghrelin,leptin,adiponectin,insulin and insulin-like growth factor(IGF-Ⅰ),were measured in 30 healthy subjects,and 60 gastric cancer patients of which 30 suffered from cancer-induced cachexia and 30 served as a control group. The relationships between hormones,body mass index(BMI) loss ratio,age,gender,and Glasgow Prognostic Score(GPS) were investigated. RESULTS:Cachexia patients had higher tumor stage and GPS when compared with non-cachexia patients(P < 0.05). Ghrelin,resistin,leptin,adiponectin and IGF-Ⅰ,showed a significant correlation with BMI loss ratio and GPS(P < 0.05). A strong correlation was seen between GPS and BMI loss(R = -0.570,P < 0.0001). Multivariate analysis indicated that BMI loss was significantly independent as a predictor of ghrelin,resistin,leptin and IGF-Ⅰ(P < 0.05). Existence of an important significant relationship between resistin and insulin resistance was also noted. CONCLUSION:These results showed that serum ghrelin,leptin,adiponectin,and IGF-Ⅰ play important roles in cachexia-related gastric cancers. No relationshipwas found between resistin and cancer cachexia. Also,because of the correlation between these parameters and GPS,these parameters might be used as a predictor factor. | Mustafa Kerem Zafer Ferahkose Utku Tonguc Yilmaz Hatice Pasaoglu Ebru Ofluoglu Abdulkadir Bedirli Bulent Salman Tevfik Tolga Sahin Murat Akin | 2008 | World Journal of Gastroenterology2008，14，23： | 4 |

| 6 | The value of prognostic markers for pediatric trauma patients显示文摘BACKGROUND: Despite the rapid development of pediatric intensive care medicine, there are still limited data in the literature regarding the follow-up of pediatric trauma patients in pediatric intensive care units(PICUs). In this study, we aim to evaluate our experience with children admitted and followed up with the diagnosis of trauma at our PICU.METHODS: We evaluated the retrospective data of 77 pediatric trauma patients who were admitted to the PICU at Sancaktepe Sehit Prof. Dr. IlhanVarank Training and Research Hospital from August 2020 to December 2022. The demographic data, clinical parameters and laboratory results were recorded. The primary outcome was the mortality in PICU. The performances of markers in predicting mortality were evaluated with receiver operating characteristic(ROC) curves.RESULTS: The median age of the patients was 70(33–157) months, and the median duration of hospitalization in the PICU was 6(2–11) d. Of the 77 patients, 9 died due to trauma(11,1%). Among the clinical parameters, Pediatric Risk of Mortality III(PRISM III) Score, inotrope requirement, extracorporeal treatment requirement, and mechanical ventilator requirement were significantly higher in non-survivors than in survivors. Among the laboratory parameters, procalcitonin(PCT), lactate/albumin ratio(LAR), neutrophil/lymphocyte ratio(NLR), and transfusion requirement were significantly higher in non-survivors than in survivors.CONCLUSION: In pediatric trauma patients, baseline PCT, LAR, and NLR values can be used to identify patients at risk for mortality. | Cansu Durak Ebru Guney Sahin Yasar Yusuf Can Alican Sarisaltik Kubra Boydag Guvenc | 2023 | World Journal of Emergency Medicine2023，14，6： | 1 |

| 10 | Vitamin D deficiency may predispose patients to increased risk of kidney transplant rejection显示文摘BACKGROUND Vitamin D deficiency occurs in more than 80%of kidney transplant recipients.Its immunomodulatory effects can predispose transplant recipients to rejection and chronic allograft nephropathy(CAN).This study determined the association between serum 25(OH)vitamin D,biopsy-proven allograft rejection,and CAN rates.AIM To determine the relationship between serum 25(OH)vitamin D level and biopsy-proven allograft rejection and CAN rate in renal transplant recipients.METHODS Adult renal transplant recipients followed at the clinic between January 2013 and 2018 were included.Recipients requiring graft biopsy due to declined function,hematuria,and proteinuria were reviewed.The two groups were compared regarding collected data,including the biopsy results,immunologic parameters,vitamin D,parathyroid hormone(PTH),phosphorus,albumin levels,and graft function tests.RESULTS Fifty-two recipients who underwent graft biopsy met the inclusion criteria.In all,14 recipients had a vitamin D level>15 ng/mL(group 1)vs≤15 ng/mL(group 2)in 38.In total,27 patients had biopsy-proven rejection,and 19 had CAN.There was only 1 recipient with biopsyproven rejection in group 1,whereas there were 24 patients with rejection in group 2.The rejection rate was significantly higher in group 2 than in group 1(P<0.001).Four patients were diagnosed with CAN in group 1 vs fifteen in group 2.There was no significant difference in the CAN rate between the two groups.PTH was higher at the time of graft biopsy(P=0.009,P=0.022)in group 1 with a mean of 268 pg/mL.Donor-specific antibodies were detected in 14(56.0%)of the recipients with rejection.Vitamin D level was 9.7±3.4 ng/mL in the rejection group vs 14.7±7.2 in the non-rejection group;this difference was statistically significant(P=0.003).The albumin levels were significantly lower in patients with rejection than in those without rejection(P=0.001).In univariate regression analysis of risk factors affecting rejection,sex,serum vitamin D,phosphorus and albumin were found to have an impact(P=0.027,P=0.007,P=0.023,P=0.008).In multivariate regression analysis,the same factors did not affect rejection.CONCLUSION The serum 25(OH)vitamin D level in kidney transplant recipients remained low.Although low serum vitamin D level emerged as a risk factor for rejection in univariate analysis,this finding was not confirmed by multivariate analysis.Prospective studies are required to determine the effect of serum vitamin D levels on allograft rejection. | Semih Buyukdemirci Ebru Gok Oguz Sanem Guler Cimen Hatice Sahin Sertac Cimen Mehmet Deniz Ayli | 2022 | World Journal of Transplantation2022，12，9： | 0 |
| 11 | COVID-19 infection in a kidney transplant recipient—special emphasis on pharmacokinetic interactions:A case report显示文摘BACKGROUND Solid organ transplant recipients are considered to be at high-risk of developing coronavirus disease 2019(COVID-19)-related complications.The optimal treatment for this patient group is unknown.Consequently,the treatment of COVID-19 in kidney transplant recipients should be determined individually,considering patient age and comorbidities,as well as graft function,time of transplant,and immunosuppressive treatment.Immunosuppressive treatments may give rise to severe COVID-19.On the contrary,they may also lead to a milder and atypical presentation by diminishing the immune system overdrive.CASE SUMMARY A 50-year old female kidney transplant recipient presented to the transplant clinic with a progressive dry cough and fever that started three days ago.Although the COVID-19 test was found to be negative,chest computed tomography images showed consolidation typical of the disease;thus,following hospital admission,anti-bacterial and COVID-19 treatments were initiated.However,despite clinical improvement of the lung consolidation,her creatinine levels continued to increase.Ultrasound of the graft showed no pathology.The tacrolimus blood level was determined and the elevation in creatinine was found to be related to an interaction between tacrolimus and azithromycin.CONCLUSION During the COVID-19 pandemic,various single or combination drugs have been utilized to find an effective treatment regimen.This has increased the possibility of drug interactions.A limited number of studies published in the literature have highlighted some of these pharmacokinetic interactions.Treatments used for COVID-19 therapy;azithromycin,atazanavir,lopinavir/ritonavir,remdesivir,favipiravir,chloroquine,hydroxychloroquine,nitazoxanide,ribavirin,and tocilizumab,interact with immunosuppressive treatments,most importantly with calcineurin inhibitors.Thus,their levels should be frequently monitored to prevent toxicity. | Ebru Gok Oguz Kadir Gokhan Atilgan Sanem Guler Cimen Hatice Sahin Tamer Selen Fatma AyerdenEbinc Sertac Cimen Mehmet Deniz Ayli | 2020 | World Journal of Transplantation2020，10，11： | 0 |
