Protective effects of erythropoietin against acute lung injury in a rat model of acute necrotizing pancreatitis

AIM： TO investigate the effect of exogenous erythro- poietin （EPO） administration on acute lung injury （ALI） in an experimental model of sodium taurodeoxycholate- induced acute necrotizing pancreatitis （ANP）. METHODS： Forty-seven male Wistar albino rats were randomly divided into 7 groups： sham group （n = 5）, 3 ANP groups （n = 7 each） and 3 EPO groups （n = 7 each）. ANP was induced by retrograde infusion of 5% sodium taurodeoxycholate into the common bile duct. Rats in EPO groups received 1000 U/kg intramuscular EPO immediately after induction of ANP. Rats in ANP groups were given 1 mL normal saline instead. All animals were sacrificed at postoperative 24 h, 48 h and 72 h. Serum arnilase, IL-2, IL-6 and lung tissue malondialdehyde （MDA） were measured. Pleural effusion volume and lung/body weight （LW/BW） ratios were calculated. Tissue levels of TNF-a, IL-2 and IL-6 were screened immunohistochemically. Additionally, ox-LDL accumulation was assessed with immune-fluorescent staining. Histopathological alterations in the lungs were also scored.RESULTS： The mean pleural effusion volume, calculated LW/BW ratio, serum IL-6 and lung tissue MDA levels were significantly lower in EPO groups than in ANP groups. No statistically significant difference was observed in either serum or tissue values of IL-2 among the groups. The level of tumor necrosis factor-（~ （TNF-（~） and IL-6 and accumulation of ox-LDL were evident in the lung tissues of ANP groups when compared to EPO groups, particularly at 72 h. Histopathological evaluation confirmed the improvement in lung injury parameters a~er exogenous EPO administration, particularly at 48 h and 72 h. CONCLUSION： EPO administration leads to a significant decrease in ALI parameters by inhibiting polymorphonuclear leukocyte （PMNL） accumulation, decreasing the levels of proinflammatory cytokines in circulation, preserving microvascular endothelial cell integrity and reducing oxidative stress-associated lipid peroxidation and therefore     

Acute lung injury and ARDS in acute pancreatitis: Mechanisms and potential intervention

Acute pancreatitis complicated by acute myocardial infarction – A rare association

Acute pancreatitis complicated by acute myocardial infarction has been reported very rarely. The exact mechanism of the cause of myocardial injury is not known. We report a case of 36 year old male presenting with acute pancreatitis complicated by ST elevation acute myocardial infarction (AMI). The administration of thrombolytic therapy in such patients can have deleterious effects. We report successful performance of primary angioplasty in this complicated patient.     

Original single-incision laparoscopic cholecystectomy for acute inflammation of the gallbladder

AIM: To investigate the safety and feasibility of our original single-incision laparoscopic cholecystectomy (SILC) for acute inflamed gallbladder (AIG).METHODS: One hundred and ten consecutive patients underwent original SILC for gallbladder disease without any selection criteria and 15 and 11 of these were diagnosed with acute cholecystitis and acute gallstone cholangitis, respectively. A retrospective review was performed not only between SILC for AIG and non-AIG, but also between SILC for AIG and traditional laparoscopic cholecystectomy (TLC) for AIG in the same period.RESULTS: Comparison between SILC for AIG and non-AIG revealed that the operative time was longer in SILC for AIG (97.5 min vs 85.0 min, P = 0.03). The open conversion rate (2/26 vs 2/84, P = 0.24) and complication rate (1/26 vs 3/84, P = 1.00) showed no differences, but a need for additional trocars was more frequent in SILC for AIG (5/24 vs 3/82, P = 0.01). Comparison between SILC for AIG and TLC for AIG revealed no differences based on statistical analysis.CONCLUSION: Our original SILC technique was adequately safe and feasible for the treatment of acute cholecystitis and acute gallstone cholangitis.     

Use of the FAB Crriteria for the Diagnosis of Acute Erythroleukaemia (AEL)

Abstract: Use of the FA6 criteria for the diagnosis of acute erythroleukaemia (AEL). R. K. Woodruff, I. H. Bunce, S. Johnson, A. in. Paxton and J. S. malpas, Aust. N.Z. J. med ., 1981, 11, pp. 1–7.
The criteria proposed by the French-American-British (FAB) Group for the diagnosis of acute erythroleukaemia (AEL), including the requirement for ≥ 30% marrow myeloblasts, were used in a review of patients with erythroleukaemia. Ten patients with AEL were identified, and a further twelve patients with marrows suggestive of AEL but having <30% myeloblasts were classified as having refractory anemia with excess of blasts (RAEB). The AEL patients had a poor prognosis, poor response to chemotherapy, and none showed evolution to myeloblastic or monoblastic leukaemia. In contrast, the patients with RAEB appeared to survive longer, respond better to chemotherapy, and several evolved into typical myelogenous leukaemia
The FAB criteria subdivides patients with erythroleukaemia into groups with apparent clinic pathological and prognostic differences. Further studies using these or equally strict criteria are required
