Abstract
In the present study, we investigated the effect of acrylamide (ACR) exposure during pregnancy on the ovary of female adult offspring of two subsequent generations. Sixty-day-old Wistar albino female rats were given different doses of ACR (2.5 and 10 mg/kg/day) from day 6 of pregnancy until giving birth. Females from the first generation (AF1) were fed ad libitum, and thereafter, a subgroup was euthanized at 8 weeks of age and ovary samples were obtained. The remaining females were maintained until they reached sexual maturity (50 days old) and then treated in the same way as the previous generation to obtain the second generation of females (AF2). The histopathological examination indicated a high frequency of corpora lutea along with an increased number of antral follicles that reached the selectable stage mainly at a dose of 2.5 mg/kg/day. Interestingly, ACR exposure significantly increased the mRNA levels of CYP19 gene and its corresponding CYP19 protein expression in AF1 females. The TUNEL assay showed a significantly high rate of apoptosis in stromal cells except for dose of 2.5 mg/kg/day. However, in AF2 females, ACR exposure significantly increased the number of degenerating follicles and cysts while the number of growing follicles was reduced. Moreover, in both ACR-treated groups, estradiol-producing enzyme CYP19A gene and its corresponding protein were significantly reduced, and an excessive apoptosis was produced. We concluded that the ovarian condition of AF1 females had considerable similarity to the typical early perimenopausal stage, whereas that of AF2 females was similar to the late perimenopausal stage in women.

Abstract
Background & Aims:Bleeding gastroesophageal varices are a cause of high mortality among cirrhotic patients. We aimed to investigate late mortality predictors and prognostic models using easily verified factors at admission in cirrhotic patients with acute variceal bleeding (AVB).Methods:Between January 2020 and June 2020, 142 patients with AVB from Tanta university hospital were included. Investigating multiple prognostic models was done using multiple logistic regression after identifying significant predictors of 6 months' mortality. Mortality prediction accuracy was assessed with area under the receiver operating characteristic (AUROC) curve.Results:The 6 months’ overall mortality rate was 31% (44 patients had died). AIMS56, Child-Turcotte-Pugh (CTP) grade C and MELD scores were significantly higher among non survivors (p<0.001) while Platelet-albumin-bilirubin (PALBI) was significantly more negative among survivors (P=0.001). Hepatocellular carcinoma was not significantly related to the mortality (p =0.364). Univariate analysis showed that high CTP, MELD, AIMS65 and PALBI scores were predictors of mortality and associated with decreased survival with high sensitivity and low specificity; while multivariate analysis showed that only AIMS56 was independently associated with mortality (p 0.004).Conclusion:CTP, MELD, AIMS65 and PALBI scores are simple, bed side risk scores that can be used for the prediction of 6 months’ mortality after AVB in cirrhotic patients with high sensitivities and lower specificities.

Abstract
Between June 2016 and June 2019, we surveyed 62 Mediterranean geckos, Hemidactylus turcicus, from Abu Rawash, Giza, Egypt, for the presence of endoparasites. In June 2016, we found 3 individuals to be infected with Eimeria lineri. We studied the morphology and inner structures of its sporulated oocysts, and the locations of its intestinal endogenous stages. We also extracted genomic DNA from these sporulated oocysts and successfully sequenced a 632-bp fragment of the 18S rRNA gene. Phylogenetic analyses using this partial sequence allowed us to support previous studies that assigned E. lineri to the genus Acroeimeria. Our consensus sequence was used to query similar 18S rDNA sequences from GenBank, and 14 sequences were selected. The phylogenetic analysis inferred by maximum likelihood and Bayesian inference methods gave similar results, as both separated the sequences into 2 clades: (1) a monophyletic group of Goussia species (from fish); and (2) a strongly supported clade that separated 4 Choleoeimeria species from a polyphyletic group of species that clustered A. lineri with 3 other Acroeimeria species and 3 Eimeria species from lizards, including Eimeria tiliquae from Tiliqua rugosa (Gray, 1825), Eimeria tokayae from Gecko gecko (L., 1758), and Eimeria eutropidis from Eutropis macularia (Blyth, 1853). Our study supports the placement of E. lineri into the Acroeimeria and contributes additional life history information toward understanding the evolutionary origin of the Eimeria-like species that have sporocysts without Stieda bodies in their oocysts and that infect saurian reptiles. We also support the concept that several traits (morphological, endogenous, and gene sequences) are both necessary and important for authors to include when making generic reassignments within the eimeriid coccidia.

Abstract
Treatment of hepatitis C virus (HCV) infection in patients with chronic kidney disease was difficult in the past because of the use of interferon (IFN). It was associated with high risk IFN-related adverse reactions due to reduced renal clearance of IFN. This study aimed to evaluate the antiviral efficacy, safety, and tolerability of ombitasvir/paritaprevir/ritonavir/ribavirin in chronic kidney disease patients infected with chronic HCV.This observational, open-label prospective study was carried out on 103 patients infected chronic HCV with different grades of renal impairment. Paritaprevir/ritonavir and ombitasvir (75/50/12.5 mg) twice daily plus ribavirin were given to the patients for 12 weeks. Dose adjustment of ribavirin was done according to degree of renal impairment.Sustained virological response (12 weeks after the end of treatment) occurred in 101 patients (98.1%). Anemia occurred in 48 patients. No serious adverse events were observed in any patient.Paritaprevir/ritonavir and ombitasvir plus ribavirin for 12 weeks was considered to be safe and effective in the treatment of chronic HCV infected patients with varying degrees of renal impairment.

Abstract
The highest recorded hepatitis C virus (HCV) prevalence worldwide is in Egypt. A high prevalence of hepatitis E virus (HEV) in chronic liver disease has been reported. The aim of this study was to study prevalence, incidence, and outcome of HCV infection in an Egyptian Nile Delta village and the relation between HEV infection and HCV-related chronic hepatic affection. This prospective cohort study included 2085 Nagreej village residents. Mass HCV screening was conducted and testing for HEV antibodies among HCV-infected patients performed. The annual incidence of HCV was recorded. Five hundred five (24.22%) of the tested villagers were positive for HCV RNA. Prevalence escalated with age and male sex. The main recorded risk factors were a history of surgery, dental procedures, hospitalization, blood transfusion, and antischistosomal treatment. HEV IgG antibody was positive in 71.4% of individuals with chronic HCV and 96.1% with advanced liver disease (cirrhosis ± hepatocellular carcinoma (HCC)). After 1 year, 29 of the 1390 HCV Ab negative villagers had a positive HCV PCR, placing an annual incidence of new HCV infections at 2.09%. The Egyptian HCV prevalence remains high with infection particularly among the elderly. The annual incidence in a small Nile Delta village is 2.086%. HCV-HEV co-infection may lead to a worse prognosis among Egyptians with chronic liver disease.

Abstract
Background and Aims The aim of this study was to detect the most important risk factors for recurrence after microwave ablation (MWA) of hepatocellular carcinoma (HCC). Methods A total of 92 patients with 110 HCC focal lesions (FLs) underwent MWA therapy. All the patients underwent triphasic CT before and after 1 and 3 months of MWA therapy. Complete ablation and recurrence rates were recorded, and the risk factors associated with recurrence were analyzed. Results Regarding the 110 HCC FLs that were detected pre-MWA, adequate ablation was recorded post-MWA procedure in 88 FLs (80%) and incomplete ablation in 22 FLs (showed residual contrast enhancement). However, there were newly detected lesions (17 FLs). The rate of recurrence was significantly higher in patients with multiple larger (> 4 cm) sized and hypervascular nodules. Diabetics were significantly associated with a higher recurrence rate of HCC. The rate of recurrence was significantly higher in patients with baseline level of serum alfa-fetoprotein (AFP) ≥200 ng/mL. Stiffer liver> 25 kPa had higher incidence for recurrence after ablation. Conclusion Meticulous follow-up is mandatory in diabetic patients, patients with AFP > 200 ng/dL starting value, hypervascular large hepatic FL, and in stiffer liver> 25 kPa, as these patients have higher incidence for recurrence after ablation.

Abstract
BACKGROUND & AIMS Hepatitis C virus infection is a major public health problem in Egypt with a risk for morbidity and mortality due to chronic liver disease complications. Worldwide, Egypt has the highest prevalence of HCV infection with the overall prevalence of about 14.7%. The aim of this study was to evaluate the antiviral efficacy, safety, and tolerability of sofosbuvir (SOF) plus Pegylated Interferon (Peg- IFNa) and Ribavirin (RBV) in Egyptian patients with chronic hepatitis C virus (HCV) infection. METHODS This study was carried out in 1200 patients with chronic hepatitis C virus infection who were eligible for interferon therapy. They were treated with the triple therapy of sofosbuvir 400 mg once daily, Peg-INF subcutaneous injection weekly for 12 weeks in combination with oral weight-based ribavirin. The primary outcome measures were the number of patients with successful eradication of the virus evidenced by the sustained virologic response (SVR) at 12 Weeks. After discontinuation of Therapy (SVR12), the secondary outcome measures were the incidence of adverse effects associated with the tested HCV therapy. RESULT The mean age of the patients was 49.32 ± 6.97 years. 45.9% of them were males and 54.1% were females.70 patients (5.8%) had a history of previous HCV treatment. ''1077 (89.8%)'' of patients achieved successful eradication of virus while ''106 (8.8%)'' were resistant to treatment and ''17 (1.4%)'' stopped treatment. Good predictors of response to the triple therapy were female gender, treatment naive and non-cirrhotic patients. CONCLUSION The triple regimen of Pegylated interferon, sofosbuvir plus ribavirin is safe and effective in the treatment of Egyptian patients with hepatitis C virus and is associated with real-life SVR12 rates of 89.8%.

Abstract
BACKGROUND/AIMS The development of esophageal varices (EV) and resultant bleeding are the most critical complications of portal hypertension. Upper gastrointestinal endoscopy is the gold standard for diagnosis of EV. To find a non-invasive method for diagnosis of EV and to predict the bleeding risk is appealing and would decrease the cost and discomfort of upper endoscopy. The aim of our study was to evaluate the blood ammonia level as a predictor of the presence of EV and of a high risk of bleeding. MATERIALS AND METHODS In this cross-sectional study, a total of 359 patients with cirrhosis were examined for the presence of EV by upper endoscopy. Abdominal ultrasonography, calculation of the Child-Pugh score, and measurement of blood ammonia were performed for each patient. RESULTS The blood ammonia level was significantly higher in patients with EV than in those without it (p<0.001), and in patients with a high risk of variceal bleeding than in those with a low risk (p=0.026). CONCLUSION An increased blood ammonia level and splenic vein diameter are predictors for the presence of EV and bleeding risk factors. The blood ammonia level may be clinically useful as it correlates with and is an independent predictor for both the endoscopic risk signs and risk factors of bleeding, and therefore, it could be used in patients with cirrhosis to decrease the number of screening endoscopies they are subjected to.

Abstract
A series of ruthenium(ii) complexes with N-heterocyclic carbene ligands were successfully synthesized by transmetalation reactions between silver(i) N-heterocyclic carbene complexes and [RuCl2(p-cymene)]2 in dichloromethane under Ar conditions. All new compounds were characterized by spectroscopic and analytical methods. These ruthenium(ii)–NHC complexes were found to be efficient precatalysts for the transfer hydrogenation of ketones by using 2-propanol as the hydrogen source in the presence of KOH as a co-catalyst. The antibacterial activity of ruthenium N-heterocyclic carbene complexes 3a–f was measured by disc diffusion method against Gram positive and Gram-negative bacteria. Compounds 3d exhibited potential antibacterial activity against five bacterial species among the six used as indicator cells. The product 3e inhibits the growth of all the six tested microorganisms. Moreover, the antioxidant activity determination of these complexes 3a–f, using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) as reagent, showed that compounds 3b and 3d possess DPPH and ABTS antiradical activities. From a concentration of 1 mg ml−1, these two complexes presented a similar scavenging activity to that of the two used controls gallic acid (GA) and butylated hydroxytoluene (BHT). From a concentration of 10 mg ml−1, the percentage inhibition of complexes 3b and 3d was respectively 70% and 90%. In addition, these two Ru–NHC complexes exhibited antifungal activity against Candida albicans. Investigation of the anti-acetylcholinesterase activity of the studied complexes showed that compounds 3a, 3b, 3d and 3e exhibited good activity at 100 μg ml−1 and product 3d is the most active. In a cytotoxicity study the complexes 3 were evaluated against two human cancer cell lines MDA-MB-231 and MCF-7. Both 3d and 3e complexes were found to be active against the tested cell lines showing comparable activity with examples in the literature. A series of ruthenium(ii) complexes with N-heterocyclic carbene ligands were successfully synthesized by transmetalation reactions between silver(i) N-heterocyclic carbene complexes and [RuCl2(p-cymene)]2 in dichloromethane under Ar conditions.![]()

Abstract
AIM To directly visualize Helicobacter pylori (H. pylori) by the highly sensitive and specific technique of immunohistochemical staining in colonic tissue from patients newly diagnosed with ulcerative colitis (UC).
METHODS Colonoscopic biopsies from thirty patients with newly diagnosed UC and thirty controls were stained with Giemsa stain and immunohistochemical stain for detection of H. pylori in the colonic tissue. Results were confirmed by testing H. pylori Ag in the stool then infected patients were randomized to receive either anti H. pylori treatment or placebo.
RESULTS Twelve/30 (40%) of the UC patients were positive for H. pylori by Giemsa, and 17/30 (56.6%) by immunohistochemistry stain. Among the control group 4/30 (13.3%) and 6/30 (20 %) were positive for H. pylori by Giemsa and immunohistochemistry staining respectively. H. pylori was significantly higher in UC than in controls (P = 0.04 and 0.007). All Giemsa positive patients and controls were positive by immunohistochemical stain. Four cases of the control group positive for H. pylori also showed microscopic features consistent with early UC.
CONCLUSION H. pylori can be detected in colonic mucosa of patients with UC and patients with histological superficial ulcerations and mild infiltration consistent with early UC. There seems to be an association between UC and presence of H. pylori in the colonic tissue. Whether this is a causal relationship or not remains to be discovered.

Abstract
Acute upper gastrointestinal bleeding (UGIB) affects large number of elderly with high rates of morbidity and mortality. Early identification and management of the factors predicting in-hospital mortality might decrease mortality. This study was conducted to identify the causes of acute UGIB and the predictors of in-hospital mortality in elderly Egyptian patients.286 elderly patients with acute UGIB were divided into: bleeding variceal group (161 patients) and bleeding nonvariceal group (125 patients). Patients' monitoring was done during hospitalization to identify the risk factors that might predict in-hospital mortality in elderly.Variceal bleeding was the most common cause of acute UGIB in elderly Egyptian patients. In-hospital mortality rate was 8.74%. Increasing age, hemodynamic instability at presentation, co-morbidities (especially liver cirrhosis associated with other co-morbidity) and failure to control bleeding were the predictors of in-hospital mortality.Increasing age, hemodynamic instability at presentation, co-morbidities (especially liver cirrhosis associated with other co-morbidity) and failure to control bleeding should be considered when triaging those patients for immediate resuscitation, close observation, and early treatment.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the 3rd most common cause of cancer-related death worldwide. It has evolved different immune escape mechanisms, which might include emergence of lymphoid and myeloid regulatory cells. Aim of this work: To determine the numbers of Myeloid-derived suppressor cells (MDSCs) in peripheral blood and ascitic fluid in cirrhosis and HCC and their relation to IFN-γ and α-fetoprotein (α-FP). PATIENTS AND METHODS Sixty individuals were enrolled in this study; forty cirrhotic patients with ascites; twenty without HCC (Group I), and twenty with HCC (group II) as well as twenty healthy individuals as a control group (group III). The phenotype and numbers of MDSCs were analyzed in peripheral blood of all the individuals and ascitic fluid of the patients using flow cytometry. Intracellular IFN-γ and serum alfa-fetoprotein were measured. RESULTS Significant increases in the relative and the mean number of peripheral blood MDSCs were found in the cirrhosis and HCC groups than in the control group, with the HCC group showing the highest number. MDSC count was negatively correlated with IFN-γ levels, while α-FP was positively correlated with MDSC% in the HCC group. MDSC count was low in ascitic fluid of both HCC and cirrhosis groups with no significant difference between the 2 groups. CONCLUSION A high frequency of MDSCs was detected in the peripheral blood of cirrhotic and HCC patients, indicating presence of immunosuppressive arms. These cells could be targeted to develop a new effective immunotherapy or an adjuvant to current therapies.

Abstract
Background and aims Patients with advanced systemic illness or critically ill patients may present with upper gastrointestinal tract (GIT) bleeding which may need endoscopic intervention; however, this may expose them to unnecessary endoscopy. The aim was to validate a novel scoring system for risk stratification for urgency of GIT endoscopy in critically ill patients. Methods This is an observational study conducted from January 2013 to January 2016 to analyze 300 patients with critical medical conditions and presenting with upper gastrointestinal bleeding. Meticulous clinical, laboratory, and sonographic evaluations were performed to calculate Glasgow Blatchford score (GBS) and variceal metric score for risk stratification and prediction of the presence of esophageal varices (OV). Finally, this score was applied on a validation group (n=100). Results The use of GBS and variceal metric scores in critically ill patients revealed that patients who showed a low risk score value for OV (0-4 points) and GBS <2 can be treated conservatively and discharged safely without urgent endoscopy. In patients with a low risk for varices but GBS >2, none of them had OV on endoscopy. In patients with intermediate risk score value for OV (5-8 points) and with GBS >2, 33.33% of them had varices on endoscopy. In patients with high risk score value for varices (9-13) and GBS >2, endoscopy revealed varices in 94.4% of them. Finally, in patients with very high risk score for varices (14-17), endoscopy revealed varices in 100% of them. Conclusion GBS and variceal metric score were highly efficacious in identifying critically ill patients who will benefit from therapeutic endoscopic intervention.

Abstract
OBJECTIVE To explore the mineral features of dentin and cementum in hypoplastic Amelogenesis imperfecta AI teeth. MATERIALS AND METHODS Forty-four (44) teeth cleaned and free of caries were used: 20 control and 24 affected by hypoplastic amelogenesis imperfecta. Thirty-two teeth were studied by pQCT, cut in sections, and analyzed under microradiography, polarized light microscopy, and confocal Raman spectroscopy. Eight teeth were observed under scanning electron microscope. Four teeth were used for an X-ray diffraction. The mineral density data were analyzed statistically with the Mann-Whitney U test, using GraphPad InStat software. RESULTS Both coronal dentin and radicular dentin were less mineralized in AI teeth when compared to control (respectively 6.2% and 6.8%; p < .001). Root dentinal walls were thin and irregular, while the cellular cementum layers were thick, reaching sometimes the cervical region of the tooth. Regular dentinal tubules and sclerotic dentin areas were noticed. Partially tubular or cellular dysplastic dentin and hyper-, normo-, or hypomineralized areas were noticed in the inter-radicular areas of hypoplastic AI teeth. The main mineral component was carbonate hydroxyapatite as explored by Raman spectroscopy and X-ray diffraction. CONCLUSIONS Dentin and cementum in hypoplastic AI teeth are (i) hypomineralized, (ii) constituted of carbonate hydroxyapatite, and (iii) of non-homogenous structure.

Abstract
Sepsis is one of the most serious complications after major trauma, and may be associated with increased mortality. We sought to determine whether there is an association between serum levels of interleukin-17 (IL-17) at the time of admission to the intensive care unit (ICU) and the development of sepsis. We evaluated 100 adult patients with major trauma admitted to the surgical ICU over a 6-month period. Serum levels of IL-17, IL-6, and TNF-α were determined by enzyme-linked immunosorbent assays (ELISA). The IL-17 rs1974226 genotype was determined by real-time PCR. In both non-adjusted and adjusted analyses, IL-17 was the only biomarker significantly associated with sepsis [median serum IL-17 of 72 pg/mL in sepsis versus 37 pg/mL in those without sepsis, P = 0.0001; adjusted odds ratio (OR) 3.2, P = 0.02]. No significant association was found among IL-17 rs1974226 genotypes and related serum cytokine levels. These data suggest that elevated serum IL-17 may increase the susceptibility for septic complications in polytrauma patients and so could be a useful biomarker for trauma patient management.

Abstract
BACKGROUND AND AIMS Gastric varices develop in 5% to 33% of patients with portal hypertension. Their most common form is concomitant gastroesophageal varices. Scleroligation (combined sclerotherapy and band ligation) has been used successfully in management of esophageal varices but has not been evaluated previously in the management of gastroesophageal varices. The aim of this work was evaluation of a new scleroligation technique for management of bleeding gastroesophageal varices regarding efficacy, adverse events, variceal recurrence, and survival. METHODS This study was conducted on 120 cirrhotic patients with bleeding gastroesophageal varices, whom we divided randomly into 2 groups of 60 patients each-a band ligation group and a scleroligation group. RESULTS The mean number of sessions was lower in the scleroligation group than in the band ligation group (2.22 ± 0.92 and 3.43 ± 0.67, respectively) (P < .001), as were the duration of treatment and total number of bands used. Cost and survival were comparable in the 2 groups. There was no significant difference between the 2 maneuvers regarding adverse events, recurrence rates, or rebleeding rates after obliteration. Recurrence was significantly higher in patients with larger varices, ulceration, and postprocedure pyrexia. Rebleeding was significantly higher among those who experienced postprocedure pyrexia and developed or had worsening of gastric antral vascular ectasia. CONCLUSIONS Scleroligation appears to achieve a faster rate of eradication with fewer treatment sessions and total number of bands deployed to achieve variceal obliteration than band ligation and is comparable in cost and in adverse event and recurrence rates.

Abstract
Screening endoscopy is recommended for early detection of esophageal varices (EVs) in cirrhotic patients with portal hypertension. However, this approach is limited by its invasiveness and cost. The aim of the study was to determine if platelet count can predict the presence of EVs, especially large (grade III, IV) EVs in need of prophylactic therapy, in a cohort of Egyptian patients with liver cirrhosis. In all, 110 patients with cirrhosis were prospectively analyzed. The presence of medium or large EVs was correlated with patients' platelet count and FIB-4. Esophageal varices were present in 87 (79.09%) patients. Among those with thrombocytopenia (platelet level below 150,000), 25.97% (20 patients) and 27.27% (21 patients) had EV grade II and EV grade III or IV, respectively. Whereas in patients in whom the platelet count was above 150,000, only 21.21% (7 patients) and 9.09% (3 patients) of patients had grade II EV and EV grade III or IV, respectively. A platelet count cut-off value of 149,000 was found to have specificity of 82% and sensitivity 39% for detection of presence of varices. A FIB-4 cut-off value of 3.175 was found to have an 83.3% sensitivity and 39.5% specificity in detecting large (grade III, IV) EVs. Platelet count is a noninvasive parameter with high accuracy for prediction of EVs. Cirrhotic patients with normal platelet counts (above 150,000), especially in financially deprived developing countries, can avoid screening endoscopy as they are at a low risk for variceal bleeding, and presence of large EVs in these patients is much less common than in those with thrombocytopenia. A 3.175 cut-off value of FIB-4 could be useful as a noninvasive predictor of large varices requiring prophylactic banding in cirrhotic patients.

Abstract
As there are increasing reports of fluoroquinolone resistance on use as a first- or second-line treatment for Helicobacter pylori (H pylori), we aimed at evaluation of the efficacy and safety of nitazoxanide-based regimen as a rescue regimen in Egyptian patients whose previous traditional treatment for H pylori infection failed.In total, 100 patients from the outpatient clinic of the Tropical medicine department, Tanta University hospital in whom the standard triple therapy (clarithromycin-based triple therapy) failed were enrolled in the study. Nitazoxanide (500 mg bid), levofloxacin (500 mg once daily), omeprazole (40 mg bid), and doxycyclin (100 mg twice daily) were prescribed for 14 days. Eradication was confirmed by stool antigen for H pylori 6 weeks after the end of treatment. Among the patients enrolled in the study, 44% of patients were men and the mean age for the participants in the study was 46.41 ± 8.05, 13% of patients were smokers, and 4% of patients had a previous history of upper gastro-intestinal bleeding. A total of 94 patients (94%) completed the study with excellent compliance. Only 1 patient (1%) discontinued treatment due to intolerable side effects and 5 patients (5%) did not achieve good compliance or were lost during follow up. However, 83 patients had successful eradication of H pylori with total eradication rates 83% (95 % CI 75.7-90.3%) and 88.30% (95 % CI 81.8-94.8%) according to an intention-to-treat and per-protocol analysis, respectively. Adverse events were reported in 21% of patients: abdominal pain (6%), nausea (9%) and constipation (12%), (2%) headache, and (1%) dizziness. A 2-week nitazoxanide-based regimen is an effective and safe rescue therapy in Egyptian patients whose previous standard triple therapy has failed.

Abstract
The non-classical class I human leukocyte antigen (HLA)-G molecule was found to be predominately expressed in the extravillous cytotrophoblasts at the fetal-maternal interface during pregnancy. This molecule is critically important for successful implantation during human pregnancy. The polymorphic insertion-deletion (indel) 14-base pair (bp) site localized at the 3' untranslated region was associated with HLA-G mRNA stability and isoform alternative splicing patterns, and thus may influence HLA-G function during pregnancy. We studied the association between the 14-bp indel polymorphism (rs16375) at the 3' untranslated region with recurrent spontaneous abortions in a Saudi population living in Riyadh. A group of 64 women with 2-11 successive abortions were included in this study. The control group included 62 women without reported abortions and at least 2 pregnancies, all visiting the King Khaled Hospital in Riyadh. The 14-bp indel was genotyped in the case and control groups. The frequency of the genotype +14/+14 was slightly higher in women with recurrent spontaneous abortions, but no significant differences were observed in the distribution of alleles and genotypes.

Abstract
PURPOSE Multipurpose solutions (MPS) are used daily to clean and disinfect silicone hydrogel (SiHy) contact lenses. This in vitro study was undertaken to identify the potential for interaction between MPS, SiHy surface treatments, and lens materials, which may lead to changes in the response of human corneal epithelial cells (HCEC) to MPS-soaked lenses. METHODS The MPS tested were renu fresh (formerly known as ReNu MultiPlus; ReNu), OptiFree Express (OFX), OptiFree RepleniSH, SoloCare Aqua, and Complete Moisture Plus. The SiHy materials evaluated were lotrafilcon A, lotrafilcon B, comfilcon A, galyfilcon A, and balafilcon A (BA). MPS-soaked lenses were placed on top of adherent HCEC. The effect of MPS dilutions (0.1 to 10% final concentration in medium) was also characterized. Cell viability, adhesion phenotype and caspase activation were studied after 24-h cell exposure. OFX released from lenses was determined using UV absorbance. RESULTS A significant reduction in viability (between 30 to 50%) was observed with cells exposed to lenses soaked in ReNu and OFX. A significant downregulation of α(3) and β(1) integrins, with integrin expression ranging from 60% to 75% of control (cells with no lens), was also observed with OFX and ReNu-soaked lenses. With the exception of BA, all other lenses soaked in OFX resulted in significant caspase activation, whereby over 18% of cells stained positive for caspases. Minimal caspase activation was observed in cells exposed to ReNu and Solo soaked lenses. For both OFX and ReNu, exposing cells to at least a 5% dilution had a significant effect on viability and integrin expression. While Complete and Solo did not lead to reduction in viability, cells exposed to a 10% dilution showed reduced integrin expression down to less than 70% of control value. Comparing cell response to diluted MPS solutions and various MPS-soaked lenses showed that it is not possible to reliably use cell response to MPS dilution alone to assess MPS biocompatibility. CONCLUSIONS Our results demonstrate that the reaction of HCEC to MPS are affected by the type of lenses the MPS is released from and may potentially be influenced by the surface treatment (or lack of it) of SiHy materials.

Abstract
BACKGROUND AND AIM The aim of this study was to evaluate endoscopic band ligation plus argon plasma coagulation versus scleroligation. METHODS Patients were randomized to: Group I, 50 patients subjected to endoscopic injection sclerotherapy; Group II, 50 patients subjected to variceal band ligation; Group III, 50 patients subjected to combined endoscopic sclerotherapy and band ligation; and Group IV, 50 patients subjected to endoscopic band ligation plus argon plasma coagulation. RESULTS A comparison of the number of therapeutic sessions showed that group III underwent significantly fewer sessions. As regards post-treatment complications, Group I showed a high incidence of transient pyrexia, transient dysphagia and/or retrosternal pain and ulceration, while in group II a higher incidence of rebleeding was demonstrated, as well as a higher incidence of esophageal varix recurrence after eradication during the follow-up period. A higher mortality incidence was detected in groups I and II. The follow-up incidence did not significantly differ between the different study groups. CONCLUSION Scleroligation allows very rapid eradication of varices, has a low recurrence rate, avoids the disadvantage of high recurrence of band ligation alone, and does not require special skills over sclerotherapy or band ligation. Also, band ligation plus argon plasma coagulation allows for very rapid eradication of varices, and a low recurrence rate, with no obvious recorded complications, but it has the disadvantage of being the most expensive technique and requires special equipment that is only available in a few endoscopic centers.

Abstract
HLA-DRB1, -DQB1, TNFalpha, TNFbeta, HSP70-2 and HSP70-hom genetic polymorphisms were analyzed in 156 unrelated patients who developed mediterranean visceral leishmaniasis (MVL) due to Leishmania infantum, and 154 unrelated healthy controls, who have got asymptomatic infection with this parasite and were selected on the basis of a positive leishmanin skin test (LST). A significantly reduced frequency of HLA-DR2 was observed among MVL patients (16.1%), compared with controls (26.3%) (relative risk = 0.54; p = 0.04). HLA-DR2/DR13 as well as HLA-DQB1*0201/- genotype frequencies were significantly lower in patients vs controls (relapse rate = 0.17 and 0.46, respectively; p < 0.05). However, using Bonferroni correction, none of these associations remained significant. No association was found, between either the -308 base pair TNFalpha gene polymorphism or the NcoI polymorphism in the first intron of the TNFbeta gene and susceptibility to MVL. Analysis of PstI and NcoI polymorphisms in the coding region of HSP70-2 and HSP70-hom genes, respectively, revealed a significantly higher frequency of homozygotes for the HSP70-2/PstI negative allele, among patients (21.8%) vs controls (12.6%) (relapse rate = 1.94; p = 0.04). Again, this result was not significant after using Bonferroni correction. These results do not support association between susceptibility to MVL and the MHC class II and class III loci analyzed in this study.

Abstract
BACKGROUND Lactobacillus is a commensal germ found in the buccal cavity, the digestive tract and the vagina. Usually non-pathogenic except in case of dental caries, it can occasionally be the causal agent in severe endocarditis. CASE REPORT A 70-year-old woman developed endocarditis on an aortic valve bioprosthesis. Lactobacillus acidophilus was isolated from blood cultures of the valve after surgery. COMMENTS Forty-four cases of Lactobacillus endocarditis have been reported in the literature to date. Mortality is high (26%). The main difficulty in treatment is germ tolerance to penicillin and aminosides found in all cases. Cure requires high dose parenteral antibiotics and surgery in many cases (26%).

Abstract
Biopsy specimens for histopathological study were taken from 15 parasitologically proven cases with different clinical forms of cutaneous leishmaniasis (CL) including two patients with disseminated CL in the form of subcutaneous nodules and satellite papules. The clinical picture of these patients was also reported. The study revealed that the histopathological manifestations were variable, ranging from a diffuse infiltrate in the acute stage to a tuberculoid architecture in the chronic stage. One patient had perineural inflammatory cell infiltrate consisting of lymphocytes, plasma cells and macrophages.
