1Agmatine induces gastric protection against ischemic injury by reducing vascular permeability in rats显示文摘AIM:To investigate the effect of administration of agmatine(AGM) on gastric protection against ischemia reperfusion(I/R) injury.METHODS:Three groups of rats(6/group);sham,gastric I/R injury,and gastric I/R + AGM(100 mg/kg,i.p.given 15 min prior to gastric ischemia) were recruited.Gastric injury was conducted by ligating celiac artery for 30 min and reperfusion for another 30 min.Gastric tissues were histologically studied and immunostained with angiopoietin 1(Ang-1) and Ang-2.Vascular endothelial growth factor(VEGF) and monocyte chemoattractant protein-1(MCP-1) were measured in gastric tissue homogenate.To assess whether AKt/phosphatidyl inositol-3-kinase(PI3K) mediated the effect of AGM,an additional group was pretreated with Wortmannin(WM)(inhibitor of Akt/PI3K,15 μg/kg,i.p.),prior to ischemic injury and AGM treatment,and examined histologically and immunostained.Another set of experiments was run to study vascular permeability of the stomach using Evan's blue dye.RESULTS:AGM markedly reduced Evan's blue dye extravasation(3.58 ± 0.975 μg/stomach vs 1.175 ± 0.374 μg/stomach,P < 0.05),VEGF(36.87 ± 2.71 pg/100 mg protein vs 48.4 ± 6.53 pg/100 mg protein,P < 0.05) and MCP-1 tissue level(29.5 ± 7 pg/100 mg protein vs 41.17 ± 10.4 pg/100 mg protein,P < 0.01).It preserved gastric histology and reduced congestion.Ang-1 and Ang-2 immunostaining were reduced in stomach sections of AGM-treated animals.The administration of WM abolished the protective effects of AGM and extensive hemorrhage and ulcerations were seen.CONCLUSION:AGM protects the stomach against I/R injury by reducing vascular permeability and inflammation.This protection is possibly mediated by Akt/PI3K.Abeer A Al Masri Eman El Eter 2012World Journal of Gastroenterology2012,18,18:4
2Drainage vs. non-drainage after cholecystectomy for acute cholecystitis:a retrospective study显示文摘Many surgeons practice prophylactic drainage after cholecystectomy without reliable evidence,this study was conducted to answer the question whether to drain or not to drain after cholecystectomy for acute calculous cholecystitis.A retrospective review of all patients who had cholecystectomy for acute cholecystitis in Aseer Central Hospital,Abha,Saudi Arabia,was conducted from April 2010 to April 2012.Data were extracted from hospital case files.Preoperative data included clinical presentation,routine investigations and liver function tests.Operative data included excessive adhesions,bleeding,bile leak,and drain insertion.Complicated cases such as pericholecystic collections,mucocele and empyema were also reported.Patients who needed therapeutic drainage were excluded.Postoperative data included hospital stay,volume of drained fluid,time of drain removal,and drain site problems.The study included 103 patients allocated into two groups;group A(n = 38) for patients with operative drain insertion and group B(n = 65) for patients without drain insertion.The number of patients with preoperative diagnosis of acute non-complicated cholecystitis was significantly greater in group B(80%) than group A(36.8%)(P < 0.001).Operative time was significantly longer in group A.All patients who were converted from laparoscopic to open cholecystectomy were in group A.Multivariate analysis revealed that hospital stay was significantly(P < 0.001) longer in patients with preoperative complications.There was no added benefit for prophylactic drain insertion after cholecystectomy for acute calculous cholecystitis in non-complicated or in complicated cases.Mohammed A Bawahab Walid M Abd El Maksoud Saeed A Alsareii Fahad S Al Amri Hala F Ali Abdul Rahman Nimeri Abdul Rahman M Al Amri Adel A Assiri Mohammed I Abdul Aziz 2014The Journal of Biomedical Research2014,28,3:3
3Consensus statement on the epidemiology,diagnosis,prevention,and management of cow's milk protein allergy in the Middle East:a modified Delphi-based study显示文摘Background This study aimed to develop an expert consensus regarding the epidemiology,diagnosis,and management of cow’s milk protein allergy(CMPA)in the Middle East.Methods A three-step modified Delphi method was utilized to develop the consensus.Fifteen specialized pediatricians participated in the development of this consensus.Each statement was considered a consensus if it achieved an agreement level of>80%.Results The experts agreed that the double-blind placebo-controlled oral challenge test(OCT)should be performed for 2-A weeks using an amino acid formula(AAF)in formula-fed infants or children with suspected CMPA.Formula-fed infants with confirmed CMPA should be offered a therapeutic formula.The panel stated that an extensively hydrolyzed formula(eHF)is indicated in the absence of red flag signs.At the same time,the AAF is offered for infants with red flag signs,such as severe anaphylactic reactions.The panel agreed that infants on an eHF with resolved symptoms within 2-4 weeks should continue the eHF with particular attention to the growth and nutritional status.On the other hand,an AAF should be considered for infants with persistent symptoms;the AAF should be continued if the symptoms resolve within 2-4 weeks,with particular attention to the growth and nutritional status.In cases with no symptomatic improvements after the introduction of an AAF.other measures should be followed.The panel developed a management algorithm,which achieved an agreement level of 90.9%.Conclusion This consensus document combined the best available evidence and clinical experience to optimize the management of CMPA in the Middle East.Moustafa A.El-Hodhod Mortada H.F.El-Shabrawi Ahmed AIBadi Ahmed Hussein AM Almehaidib Basil Nasrallah Ebtsam Mohammed AIBassam Hala El Feghali Hasan M.Isa Khaled Al Saraf Maroun Sokhn Mehdi Adeli Najwa Mohammed Mousa Al-Sawi Pierre Hage Suleiman Al-Hammadi 2021World Journal of Pediatrics2021,17,6:3
4Treatment of hepatitis C virus genotype 4 with peginterferon alfa-2a: Impact of bilharziasis and fibrosis stage显示文摘AIM: To evaluate pegylated interferon alpha2a (PegIFN- α2a) in Egyptian patients with HCV genotype 4, and the impact of pretreatment viral load, co-existent bilharziasis and histological liver changes on response rate. METHODS: A total of 73 na?ve patients (61 with history of bilharziasis) with compensated chronic HCV genotype 4 were enrolled into: group A (38 patients) who received 180 mg PegIFN-alpha2a subcutaneously once weekly for a year and group B (35 patients) received IFN alpha-2a 3 MU 3 times weekly. Ribavirin was added to each regimen at a dose of 1200 mg. Patients were followed for 72 wk and sustained response was assessed. RESULTS: Significant improvement in both end of treatment response (ETR) (P < 0.002) and sustained response (SR) (P < 0.05) was noted with pegylated interferon, where ETR was achieved in 29 (76.3%) and 14 patients (40%) in both groups respectively, and 25 patients in group A (65.8%) and 9 (25.7%) in group B could retain negative viraemia by the end of follow up period. Sustained virological response (SVR) showed a significant negative correlation with age and positive correlation with pretreatment inflammation in patients receiving PegIFN. Viral clearance after 3 mo of therapy was associated with high incidence of ETR and SR (P < 0.001), but without significant difference between both forms of interferon. Significant improvement in response was achieved in patients with high grade fibrosis (grade 3 and 4) with PegIFN-α2a, where SR was seen in 5 out of 13 patients in group A, but none in group B. There was no significant difference in response betweenbilharzial and non-bilharzial patients in both groups. In terms of safety and tolerability, neutropenia was the predominant side effect; both drugs were comparable. CONCLUSION: PegIFN-α2a combined with ribavirin results in improvement in sustained response in HCV genotype 4, irrespective of history of bilharzial infestation.MF Derbala SR Al Kaabi NZ El Dweik F Pasic MT Butt R Yakoob A Al-Marri AM Amer N Morad A Bener 2006World Journal of Gastroenterology2006,12,35:3

6Pancreatic pseudocyst or a cystic tumor of the pancreas?显示文摘Pancreatic pseudocysts are the most common cystic lesions of the pancreas and may complicate acute pancreatitis, chronic pancreatitis, or pancreatic trauma. While the majority of acute pseudocysts resolve spontaneously, few may require drainage. On the other hand, pancreatic cystic tumors, which usually require extirpation, may disguise as pseudocysts. Hence, the distinction between the two entities is crucial for a successful outcome. We conducted this study to highlight the fundamental differences between pancreatic pseudocysts and cystic tumors so that relevant management plans can be devised. We reviewed the data of patients with pancreatic cystic lesions that underwent intervention between June 2007 and December 2010 in our hospital. We identified 9 patients(5 males and 4 females) with a median age of 40 years(range, 30–70 years). Five patients had pseudocysts, 2 had cystic tumors, and 2 had diseases of undetermined pathology. Pancreatic pseudocysts were treated by pseudocystogastrostomy in 2 cases and percutaneous drainage in 3 cases. One case recurred after percutaneous drainage and required pseudocystogastrostomy. The true pancreatic cysts were serous cystadenoma, which was treated by distal pancreatectomy, and mucinous cystadenocarcinoma, which was initially treated by drainage, like a pseudocyst, and then by distal pancreatectomy when its true nature was revealed. We conclude that every effort should be exerted to distinguish between pancreatic pseudocysts and cystic tumors of the pancreas to avoid the serious misjudgement of draining rather than extirpating a pancreatic cystic tumor. Additionally, percutaneous drainage of a pancreatic pseudocyst is a useful adjunct that may substitute for surgical drainage.Mohammad Ezzedien Rabie Ismail El Hakeem Mohammad Saad Al Skaini Ahmad El Hadad Salim Jamil Mian Tahir Shah Mahmoud Obaid 2014Chinese Journal of Cancer2014,33,2:2
7Abscess of the caudate lobe of the liver, a rare disease with a challenging management: a case report显示文摘We reported a rare case of abscess of the caudate lobe of the liver in a 60-year old man.We first tried computed tomography(CT)guided percutaneous drainage of the abscess but failed to eradicate the infection.Deterioration of the general condition of the patient necessitated open surgical drainage,which resulted in cure of the abscess.The peculiar anatomical location of caudate lobe abscess introduces a great challenge for the surgeon in planning the appropriate management and paucity of patients with caudate lobe abscess has led to lack of guidelines for management.The non-operative interventional radiology approach has become the therapeutic choice for pyogenic liver abscess,but is it applicable also for caudate lobe abscess?Nasser A.
