Harmonic Scalpel® treatment of haemorrhoidectomy versus Milligan–Morgan's method

Haemorrhoidal disease develops slowly. In comparison to electrocautery, surgical intervention with the Harmonic Scalpel® shear is a revolutionary approach for ablation of symptomatic fourth and third degree haemorrhoids. In contrast to electrocautery, Harmonic Scalpel® causes less discomfort because of its restricted lateral thermal injury during tissue dissection. The purpose of this study was to observe how effective Harmonic Scalpel® is at reducing postoperative problems after a haemorrhoidectomy. A harmonic US scalpel device was utilized to do the hemorrhoidectomy in group A, while a monopolar electrocautery device was employed in group B, which included 82 individuals. In this study, postoperative pain was more statistically significant in the Harmonic haemorridectomy group A than in group B haemorridectomy, in keeping with a pain numerical analogue scale of 1 to 10. The postoperative pain in group A was statistically significant on the 1st, 2nd, 4th, 7th, 14th, and 28th days of follow up, p<0.001. Time off work and patient satisfaction were statistically significant in the harmonic group, 2.50±0.066 compared to the surgery group, 3.56±0.070 (p<0.05). Healing of postoperative ulcers was statistically significant in the harmonic group (2.640.062 vs. 4.120.062 in surgery) (p<0.037).&nbsp

Risk Scoring Systems to Predict In-Hospital Mortality in Patients with Acute Variceal Bleeding due to Hepatitis C Virusinduced Liver Cirrhosis

This study was designed to validate and to compare accuracy of the prognostic scores; mainly Child Turcotte Pugh (CTP), creatinine-modified Child Turcotte Pugh (CTP-Cr), model for end-stage liver disease (MELD), albumin bilirubin score (ALBI), and AIMS65, for the predicting clinical outcomes in cirrhotic Egyptian patients presenting with acute variceal bleeding (AVB). Retrospective single center study involving 725 patients presenting with AVB due to liver cirrhosis and HCV infection either alone or mixed with HBV infection. In hospital mortality prognostic scores were calculated; mainly CTP, modified CTP-Cr, MELD, ALBI, AIMS65. The endpoint is either patient improvement or death. 725 patients were included over 1-year period. 547 (75%) survived and 178 (25%) died. Patients presented with hematemesis (515/71%), melena (120/16.5%) or hematemesis and melena (90/12.5%). Those with hematemesis for the first time were 241 (33%) and recurrent attacks were 484 (66.8%). The non-survivors had significantly more incidence of shock on presentation, more blood transfused units, history of NSAIDS intake, more ICU admission days and were more likely to be Childs C. Child, modified CTP-Cr, MELD, ALBI and ALMS65 scoring systems showed significant difference between survivors and nonsurvivors. Liver specific scores (Child, MELD) and gastrointestinal bleeding scoring systems (ALBI, AIMS65) are useful in predicting clinical outcomes of AVB in cirrhotic patients. CTP-Cr score had the highest prognostic capability of in hospital mortality. Presence of active bleeding at time of endoscopy, more complications, old age, shock and higher CPT-Cr score are additional independent predictors of in hospital mortality

Nanoconjugated long non-coding RNA MEG3 as a new therapeutic approach for Hepatocellular carcinoma

Background: Hepatocellular carcinoma (HCC) is an aggressive human cancer with a poor prognosis. Long non-coding RNAs (lncRNA) have multiple functions: epigenomic regulation, gene transcription, protein-coding gene translation, and genome defense. The involvement of lncRNAs in therapy offers a vast step in cancer treatment. Objective: In the current study, a novel therapeutic regimen using polymer nanoparticle-mediated delivery of lncRNA was designed to control the progression of hepatocarcinogenesis. Methods: One hundred mice were divided into 5 groups. The first group served as a normal-control group and was injected with saline, whereas the pathological-control group (the second group) was injected with N-Nitrosodiethylamine (DEN) weekly for 16 weeks. Group 3, Group 4, and Group 5 were injected intrahepatically with polymer nanoparticles (NPs) alone, lncRNA MEG3 alone, and conjugated NPs, respectively, once/week for four weeks starting on the 12th week after DEN injection. After 16 weeks, animals were euthanized, and liver specimens and blood samples were collected for pathological, molecular, and biochemical assessment. Results: Compared to the pathological-control group, nanoconjugates lncRNA MEG3 demonstrated a significant improvement in histopathology and tumour-associated biomarkers. Furthermore, the expression of the SENP1 and PCNA was downregulated. Conclusion: MEG3 conjugated nanoparticles can be considered a novel therapeutic regimen for HCC

Predictors of In-Hospital Mortality in patients with hepatocellular carcinoma and Acute Variceal bleeding

Introduction: Detection of hepatocellular carcinoma (HCC) in cirrhotic patients remains a serious, unsolved problem, and the risk factors for acute variceal bleeding (AVB) in HCC patients remain unclear. This study aimed to determine the in-hospital mortality (IHM) and factors influencing the clinical outcomes of AVB in patients with liver cirrhosis and HCC. Methods: This was a retrospective, non-randomized, clinical study that was conducted in 2014. The study was conducted on 70 patients with liver cirrhosis and HCC presenting by acute upper gastrointestinal bleeding (AUGIH). All patients were examined endoscopically within 24 hours from presentation and bleeding varices accounted for AUGIH. Full medical history, clinical examination, and laboratory and radiologic data were collected from admission charts, and hospital medical records were statistically analyzed with SSPS version 22. Results: Thirty-two patients (45.7%) survived and 38 died (54.3%). Survivors are more likely to be Child-Pugh class A or B, and the non-survivors were class C. The Model for End-Stage Liver Disease (MELD) was highly predictive of IHM at an optimized cut-off value of ≥ 12.9. Higher esophageal varices grades and presence of active bleeding on index endoscopy were significant (p < 0.01) in the non-survivors compared to survivors. Complications of liver cirrhosis and associated major comorbidity were significantly higher (p < 0.01) in the non- survivors than the survivors. Univariate logistic regression analysis identified higher Grade Esophageal Varices and number of transfused packed red blood cells units as two independent predictors of IHM. Conclusions: IHM was particularly high (54.3%) among HCC patients with AVB who had MELD score > 12.9, higher grade Esophageal Varices, active bleeding on index endoscopy, more increased needs for blood transfusion, longer hospital stay, decompensated liver disease with major comorbidity

Snails and Fish as Pollution Biomarkers in Lake Manzala and Laboratory C: Laboratory Exposed Snails to Chemical Mixtures

Snails are considered as suitable diagnostic organisms for heavy metal–contaminated sites. Biomphalaria alexandrina snails are used in this work as pollution bioindicators after exposure to chemical mixtures consisted of heavy metals (HM); zinc (Zn), copper (Cu) and lead (Pb); and persistent organic pollutants; Decabromodiphenyl ether 98% (D) and Aroclor 1254 (A). The impacts of these tested chemicals, individual and mixtures, on liver and kidney functions, antioxidant enzymes, complete blood picture, and tissue histology were studied. Results showed that Cu was proved to be the highly toxic against snails than Zn and Pb where LC50 values were 1.362, 213.198 and 277.396 ppm, respectively. Also, B. alexandrina snails exposed to the mixture of HM (¼ LC5 Cu, Pb and Zn) showed the highest bioaccumulation of Cu and Zn in their whole tissue, the most significant increase in AST, ALT & ALP activities and the highest significant levels of total protein, albumin and globulin. Results showed significant alterations in CAT activity in snail tissue extracts while snail samples exposed to most experimental tests showed significant increase in GST activity. Snail samples that exposed to HM mixtures showed a significant decrease in total hemocytes count while snail samples that exposed to mixtures containing A & D showed a significant increase in total hemocytes and Hyalinocytes. Histopathological alterations in snail samples exposed to individual HM and their mixtures for 4 weeks showed degeneration, edema, hyper trophy and vaculation in head-foot muscle, degeneration and necrotic changes in the digestive gland and accumulation in most tested organs. Also, the hermaphrodite gland showed mature ova with irregular shape and reduction in sperm number. In conclusion, the resulted damage and alterations in B. alexandrina studied parameters can be used as bioindicators to the presence of pollutants in its habitats

Impact of hyponatremia on frequency of complications in patients with decompensated liver cirrhosis

Introduction: Hyponatremia is common in cirrhosis. The relationship between hyponatremia and severity of cirrhosis is evidenced by its close association with the occurrence of complications, the prevalence of hepatic encephalopathy, hepatorenal syndrome, spontaneous bacterial peritonitis, refectory ascites, and hepatic hydrothorax. The aim of this study was assess the impact of hyponatremia on the occurrence of both liver-related complications and the hemodynamic cardiovascular dysfunction. Methods: This prospective study was conducted in 2015 on 74 patients with liver cirrhosis. The patients were\ud from the Gastroenterology and Hepatology Department of Theodor Bilharz Research Institute in Giza, Egypt. The patients were divided into three groups according to their serum level of sodium. Group 1 included 30 patients with serum sodium >135 meq/L, group 2 included 24 patients with serum sodium between135 and 125 meq/L, and group 3 included 20 patients with serum sodium <125 meq/L. For each of the patients, we conducted aclinical examination, laboratory investigations, chest X-ray, ECG, abdominal sonar, and echocardiography. Results: Hyponatremia was found in 59.46% of our cirrhotic patients, and they showed significantly increased Model for End-Stage Liver Disease (MELD) score, MELD-Na score, QTc interval, Pulmonary vascular resistance (PVR) and inferior vena cava (IVC) collapsibility, and decreased SVR and IVC diameter. Also hepatic encephalopathy, ascites, renal failure, infectious complications, and pleural effusion were significantly more common in hyponatremic cirrhotic patients. Conclusion: In cirrhosis, hyponatremia is more common in severe cardiovascular dysfunction and associated with increased risk of hepatic encephalopathy, ascites, illness severity scores, renal failure, infectious complications, and pleural effusion. We recommend selective oral administration of vasopressin V2-receptor antagonist, tolvaptan, which acts to increase the excretion of free water, thereby resolving hypervolemic hyponatremia and may have the potential to improve outcomes in these patients

Bioactive chemical constituents of Curcuma longa L. rhizomes extract inhibit the growth of human hepatoma cell line (HepG2)

The present study was designed to identify the chemical constituents of the methanolic extract of Curcuma longa L. rhizomes and their inhibitory effect on a hepatoma cell line. The methanolic extract was subjected to GC-MS analysis to identify the volatile constituents and the other part of the same extract was subjected to liquid column chromatographic separation to isolate curcumin. The inhibition of cell growth in the hepatoma cell line and the cytopathological changes were studied. GC-MS analysis showed the presence of fifty compounds in the methanolic extract of C. longa. The major compounds were ar-turmerone (20.50 %), β-sesquiphellandrene (5.20 %) and curcumenol (5.11 %). Curcumin was identified using IR, 1H and 13C NMR. The inhibition of cell growth by curcumin (IC50 = 41.69 ± 2.87 μg mL-1) was much more effective than that of methanolic extract (IC50 = 196.12 ± 5.25 μg mL-1). Degenerative and apoptotic changes were more evident in curcumin- treated hepatoma cells than in those treated with the methanol extract. Antitumor potential of the methanolic extract may be attributed to the presence of sesquiterpenes and phenolic constituents including curcumin (0.051 %, 511.39 μg g-1 dried methanol extract) in C. longa rhizomes
