Purpose:To study the relationship between the axial length and personal A-constant for the 1-piece Tecnis (Abbott ZCB00), AcrySof MA60AC (Alcon) and the Quatrix aspheric preloaded (CROMA) intraocular lenses (IOL).Materials and Methods:Patients matching the inclusion criteria were further subdivided according to the implanted IOL in this prospective comparative study. The obtained refractive outcomes were introduced into the formula installed in the biometry machine (Humphrey model 820 ultrasonic biometer) to obtain the personal A-constant for each eye. Polynomial regression analysis was done to study the individualized A-constant for each type of IOL in relation to preoperative axial length measurement.Results:Two hundred and forty five eyes of 186 patients were enrolled into this study, of whom 73 eyes with Tecnis 1-piece, 116 eyes with MA60AC, and 56 eyes with Quatrix. The median of personalized A-constant for Tecnis 1-piece, MA60AC, and Quatrix were 119.21 (SD 1.3, Std. Mean error 0.15), 119 (SD 1.2, Std. Mean error 0.11) and 120.4 (SD 1.2, Std. Mean error 0.16) respectively. Regression plots for the same range of axial length among all the groups showed that the Tecnis1 group followed the same pattern of the Quatrix group in which there was a linear relationship of a trend towards myopia when the axial length had increased and a hyperopic shift when decreased. This relationship changed into a plateau when the axial length became in the range of 23.5 mm to 27 mm in the MA60AC group.Conclusions:Personal A-constant follows different trends with different IOLs even for the same range of axial length.

AIMTo evaluate the reversibility of minimal hepatic encephalopathy (MHE) following liver transplantation (LT) in Egyptian cirrhotic patients.METHODSThis prospective study included twenty patients with biopsy-proven liver cirrhosis listed for LT and twenty age- and sex-matched healthy control subjects. All underwent neuro-psychiatric examination, laboratory investigations, radiological studies and psychometric tests including trail making test A (TMT A), TMT B, digit symbol test and serial dotting test. The psychometric hepatic encephalopathy score (PHES) was calculated for patients to diagnose MHE. Psychometric tests were repeated six months following LT in the cirrhotic patient group.RESULTSBefore LT, psychometric tests showed highly significant deficits in cirrhotic patients in comparison to controls (P < 0.001). There was a statistically significant improvement in test values in the patient group after LT; however, their values were still significantly worse than those of the controls (P < 0.001). The PHES detected MHE in 16 patients (80%) before LT with a median value of -7 ± 3.5. The median PHES value was significantly improved following LT, reaching -4.5 ± 5 (P < 0.001), and the number of patients with MHE decreased to 11 (55%). The pre-transplant model for end-stage liver disease (MELD) score ≥ 15 was significantly related to the presence of post-transplant MHE (P = 0.005). More patients in whom reversal of MHE was observed had a pre-transplant MELD score < 15.CONCLUSIONReversal of MHE in cirrhotic patients could be achieved by LT, especially in those with a MELD score < 15.

Nonalcoholic fatty liver disease (NAFLD) is a spectrum of hepatic diseases linked to metabolic and cardiovascular disorders that impair quality of life and increase morbidity and mortality. There has been significant interest in replacing conventional diagnostic tools such as liver biopsy with non-invasive biomarkers for the diagnosis of NAFLD. Thymosin Beta 4 (Tβ4) is a G-actin sequestering peptide involved in many critical biological processes. This study aimed to evaluate the role of Tβ4 in the diagnosis of NAFLD, and its relation to metabolic syndrome. Eighty patients were enrolled in this study, divided into two equal groups of NAFLD cases (n=40) and a control group (n=40). The two groups were subjected to history taking, physical examination, measurement of waist circumference and body mass index (BMI). Laboratory workup included serum Tβ4, insulin resistance (HOMA-IR), fibrosis-4 score (FIB-4), fatty liver index (FLI) and NAFLD fibrosis score (NFL) were calculated for both groups. Serum Tβ4 was significantly lower in NAFLD patients (P <0.001) and there was a significant positive correlation between serum Tβ4 and HDL (P = 0.034). On the other hand, there was a significant negative correlation between serum Tβ4 and waist circumference (P <0.001), total cholesterol level (P <0.001), insulin level (P <0.001), HOMA-IR (P <0.001), serum triglycerides (P= 0.025) and FLI (P = 0.004). Serum Tβ4 at a cut-off value of ≤900 ng/ml had 100 % sensitivity, 100 % specificity, 100% positive predictive value and 100% negative predictive value for the prediction of NAFLD. In conclusion, serum Tβ4 could be used as a biomarker for the diagnosis of NAFLD.

Background Hepatocellular carcinoma (HCC) is the fifth most common malignancy and the second leading reason of cancer-associated deaths around the world.The poor outcome of patients with HCC is attributed to late detection, with more than two-thirds of patients diagnosed at advanced stages of the disease. However, a considerable improvement in survival has been observed (5-year survival up from 40% to 70%) when patients are diagnosed at an early stage and receive potentially curative therapy in the form of liver transplantation, surgical resection, or tumor ablation. Objective Evaluate levels of serum Dickkopf-1, & its significance as a diagnostic & prognostic marker for Hepatocellular Carcinoma. Aim of the work assess the possible diagnostic role of serum DKK1 compared to alpha- fetoprotein which is the slandered marker used for diagnosis of HCC.also DKK1 act as prognostic marker for Hepatocellular Carcinoma. Pateints and Methodes This study had been carried out on 45 subjects diveded into 2 groups,first group include 30 pateints with liver cirrhosis,and second group 15 pateints with HCC.In this group of patients DKK1 was withdrawn before TACE & 3 months post intervention, age range 25-73 year selected from Internal medicine and Hepatology outpatient clinics and inpatient wards at Ain shams university hospitals from March 2019 till January 2020.They were distributed as 25 males and 20 females. There were 13 pateints with child A,17 pateints with child B, & 15 pateints (20%) with child C. Results In this study, the serum levels of serum DKK1 were highest in patients with HCC compared to those with liver cirrhosis. Also DKK1 values significally decreased after intervention(TACE). Conclusion Serum DKK1 act as a diagnostic marker for HCC and its level significally decrease after TACE

Background Spontaneous Bacterial Peritonitis is the most common form of infection seen in-patient with cirrhosis and is responsible of hospital mortality rate of approximately 32%, the increasing trend of resistance associated with low treatment efficacy of traditional therapy in nosocomial infection. It has been considered a life-threatening infection that requires a prompt diagnosis and treatment. Aim To evaluate the effect of certain prognostic factors namely Child -Pugh score, MELD Score and isolated organisms by bacterial cultures & Identifying organisms responsible for resistant SBP will guide in modification of antimicrobial treatment regimen. Methods A prospective cohort Study was conducted on 100 Egyptian cirrhotic and Ascetic patients for whom suspected for Spontaneous bacterial peritonitis (SBP) with no prior antimicrobial treatment. SBP and RSBP(Resistant spontaneous bacterial peritonitis) was diagnosed through history-taking through examination, clinical assessment and laboratory investigations, including ascetic fluid study analysis and the detection of culture sensitivity, recruited from the Gastrointestinal and Hepatology Unit of Nasser Institute Hospital, over a period from December 2016 to April 2017. Results Our study showed that out of 100 cirrhotic and Ascetic, out of 100; 60 were diagnosed SBP, out of those 60 resistant SBP were diagnosed in 30 patients with culture positive that responded on 2nd line treatment; Meropenem; 1g IV (with dose modification according creatinine clearance level) every 8 h for 5 days are the cases group and remained 30 that respond on the usual 1st line treatment; 2g of intravenous (IV) Cefotaxime (CTX) every 8h for 5days; are the control group. We found that there was no statistical significant difference between the studied groups as regards age and sex, Fever and abdominal pain were the most frequent manifestations in both group. There was statistically significant difference between both groups according to the grade of Ascites, Hepatic encephalopathy and at the peritoneal fluid analysis after 48 h of 2 gram of CTX for TLC and Neutrophil & also Cl, Glucose and LDH (P value&lt;0.05). The RSBP prediction by Child score at cut off value ≥9.5 and the most frequent organism is Klebsiella in cultures results among RSBP which is being responded on Meropenem treatment. Conclusion RSBP associated with child c patients at cut off value≥9.5 so Child score is more useful as prognostic tool than MELD score although MELD score has higher accuracy prediction than Child score because it is vulnerable in Laboratory measurement.

Purpose: The aim of this study was to investigate the diagnostic value of a topical prednisolone acetate 1% provocative test for steroid-induced ocular hypertension before intravitreal triamcinolone acetonide injection. Methods: This is a prospective, single-center, randomized controlled study at Kasr El Aini Hospital, Cairo University. Patients scheduled for intravitreal triamcinolone acetonide were enrolled and randomly allocated in a ratio 2:1 to either Group A: received prednisolone acetate provocative test and those who did not develop SIOH proceeded with intravitreal triamcinolone acetonide or Group B: did not receive prednisolone acetate provocative test and proceeded directly to intravitreal triamcinolone acetonide. Intraocular pressures were measured weekly for 4 weeks following intravitreal triamcinolone acetonide. Steroid-induced ocular hypertension is defined as intraocular pressure increase of 5 mmHg or more from baseline after prednisolone acetate provocative test or intravitreal triamcinolone acetonide. Results: A total of 66 eyes (66 patients) were included. Of which, 10 eyes (23.8%) showed prednisolone acetate provocative test steroid-induced ocular hypertension during the 4-week period. Intravitreal triamcinolone acetonide steroid-induced ocular hypertension was less likely to develop in Group A (prednisolone acetate provocative test non-steroid-induced ocular hypertension, n = 32, 31.25%) than in group B (n = 24, 54.2%) (p = 0.006, odds ratio: 0.178, 95% CI: 0.53–0.596). Our test achieved a negative predictive value of 68.75%. Conclusion: The topical prednisolone acetate provocative test may be a useful method to predict a steroid-induced ocular hypertension following intravitreal triamcinolone acetonide.
