Helicobacter pylori and non-alcoholic fatty liver disease: Is there a relationship?

Non-alcoholic fatty liver disease (NAFLD) is distinguished by liver injury due to metabolic stress, identified by diffuse hepatocyte macrovascular fatty lesions [1]. The prevalence of NAFLD is rising yearly, with a worldwide incidence rate between 20% and 30% [2]. Complex hereditary variables, improper lipid metabolism, and insulin resistance are the key characteristics of the etiology of NAFLD [3]. The research has revealed that aberrant lipid metabolism in the liver can result in dysbacteriosis in the intestinal flora; abnormality of the flora eventually encourages lipid deposition in the liver. Additionally, there is mounting proof that NALFD is linked to abnormalities in the gut flora, particularly Helicobacter pylori (H, pylori) [4]. Gram-negative bacillus, termed H pylori, has colonized the deep layers of the gastric mucosa. [5]. The global infection rate for H pylori is about 50% or higher [6]. According to research, H pylori causes gastric cancer, gastrointestinal lymphoma, peptic ulcers, and chronic gastritis [7]. Additionally, some researchers indicate a connection between H pylori and liver cancers, diabetes, and improper lipid metabolism [8]. Some studies have discovered that infection by H pylori is one of the elements for NAFLD to progress and that getting rid of H pylori can partially stop the evolution of NAFLD [9].

Cost-Effectiveness of HCV Core Antigen versus PCR for Monitoring Treatment Response in DAAS-Treated Egyptian Patients

PCR is currently the non-debatable proof for diagnosis of HCV infection as well as conclusion of treatment outcomes. HCV core antigen (HCVcAg) testing is a neglected, less expensive and less time consuming test that's presumed to achieve the same aims. The aim of this study is to find the cost-effectiveness of HCV core antigen testing in the monitoring of treatment response as an alternative to the gold-standard PCR test

Maternal age and miscarriage: A unique association curve in Sudan

This study's aim was to estimate the prevalence and maternal age and other risk factors of miscarriage among Sudanese women. Across-sectional study was conducted at the Saad Abuelela Tertiary Hospital in Khartoum, Sudan, from February to December 2019. Sociodemographic, obstetric and clinical data were collected. A multivariate logistic regression analysis was performed. Four hundred thirteen (20.5%) women reported experiencing a miscarriage. Risk factors included older age, high parity, histories of caesarean delivery, and obesity. Logistic regression showed that the lowest risk for women aged less than 20 years (adjusted odds ratio [AOR], 0.33) or 20 to 24 years (AOR, 0.57), primiparas (AOR, 0.42) and women educated below the secondary level (AOR, 0.78). Unlike the global age-associated risk of miscarriage, the risk of miscarriage among Sudanese women follows a unique curve in relation to maternal age. Interestingly, the curve showed a lower risk for women less than 20 years and at 40 years. (Afr J Reprod Health 2022; 26 [7]: 15-21).

Anti-Helicobacter pylori activity of Egyptian medicinal plants and bacteriophages

Background: Helicobacter pylori (H. pylori) is the most common cause of gastric infections worldwide. Due to antibiotic resistance and adverse effects, phytotherapy and phage therapy have been a research focus as an alternative therapy for H. pylori infection. Objectives: To assess the medicinal plant extracts and bacteriophages as a treatment of H. pylori infection. Methodology: Thirty five gastric biopsies were cultured for H. pylori isolation. Screening of medicinal plants extract efficiency was done by Disc diffusion method. Minimum inhibitory concentrations of extracts were assessed. In vivo effect of Punica granatum peel extract was tested by bacterial density and histopathology in rats. Sewage water samples were screened for H. pylori specific bacteriophages. Single plaque isolation technique was used for phage purification. Results: Ten out of 35 (28.57%) patients had positive gastric biopsy for H. pylori by culture. Four out of 10 (40%) isolates were resistant to all antibiotics. Inhibitory effect of Rosemarinus officinalis, Syzygium aromaticum, Rhus coriaria and Ammi visagna on H. pylori was detected. Punica granatum extract was the most efficient in vitro. In vivo, Punica granatum peel extract caused significant reduction of bacterial density (Pty (P<0.05) and enhanced ulcer healing. Sewage water filtrates contained 3 types ofH. pylorispecific bacteriophages. During phagepurification,phage infectivity waslost.Conclusions:Punicagranatumpeel extract revealed better in vivo activity againstH. pylorithanv standard regimen antimicrobials. Other effective plants can be beneficial inH. Pylori infection management .Loss of bacteriophage infectivity may be an obstacle to phage therapy of H. pylori

Incidence and outcomes of cases of caesarean scar ectopic pregnancy in a tertiary referral centre

Background. Caesarean scar ectopic pregnancy (CSEP) is a rare condition in which the implantation of the gestational sac takes place within the uterine scar of a previous caesarean section (CS). If the pregnancy continues within the uterus, the risk of placenta accrete or uterine rupture is increased.Objective. To investigate four treatment methods, based on each patient's clinical presentation, gestational age of the pregnancy and haemodynamic stability, for the management of CSEP.Methods. CSEP cases (N=30) were diagnosed by ultrasound at the Shatby Maternity University Hospital, Egypt. Various treatment modalities, based on gestational age, were employed to treat the patients. Treatments included suction curettage (n=12), embryo reduction with local methotrexate injection (n=12), laparoscopic excision (n=3) and excision through laparotomy (n=3). Serum levels of beta-human chorionic gonadotrophin (ß-hCG) were measured at diagnosis and weekly following treatment until the levels returned to non-pregnant values.Results. There was a significant positive correlation between gestational age in weeks and the CSEP management strategy employed. ß-hCG levels decreased from before treatment to the end of the follow-up period 3 weeks later.No cases required a hysterectomy, and no maternal complications were reported in this study.Conclusion. The appropriate CSEP management strategy varies according to gestational age. Suction and embryo reduction with local methotrexate injection offers an effective, safe and minimally invasive surgical treatment to remove ectopic pregnancy tissue. Closely monitored follow-up of patients, including serial measurement of ß-hCG levels and ultrasonographic examinations, is recommended after CSEP management

Experimental murine model of intra-abdominal infections caused by some non-albicans Candida species

Background: Even though intra-abdominal candidiasis (IAC) has been increasingly recognized, with associated high morbidity and mortality rates, its pathogenesis remains poorly understood. This model aims to study the pathogenicity and invivo susceptibility of non-albicans Candida species associated with IAC in human in order to predict the frequency of infections, outcome of clinical disease and response to antifungal therapy. Methodology: Both immunosuppressed and immunocompetent female CD-1 mice were challenged intraperitoneally with 5 x 108 CFU/ml inoculum of five non-albicans Candida strains; Candida glabrata, Candida parapsilosis, Candida lipolytica, Candida tropicalis and Candida guilliermondii. Mice were closely observed for symptoms. Treated groups received voriconazole (40 mg/kg/day) or micafungin (10 mg/kg/day) 24 hours after infection depending on invitro susceptibility results. Survival rate, mean survival time and fungal tissue burdens were recorded for all groups. Results: All infected groups developed hepatosplenomegaly, peritonitis and multiple abscesses on intra-abdominal organs and mesenteries. C. glabrata and C. lipolytica represented the most and the least virulent strains respectively in terms of survival rate, mean survival time and fungal burden in both immunosuppressed and immunocompetent models. Following treatment, all immunocompetent animals survived the entire duration of experiments (0% mortality rate), while mortality rate was relatively high (20-60%) in immunosuppressed mice. Treatment failed to eradicate the infection in immunosuppressed mice despite significant decrease of the fungal burden and increase mean survival time. Conclusion: This study reports an increasing pathogenicity of non-albicans Candida species, with persistent infection among immunosuppressed animals

Role of breast magnetic resonance imaging in early stage breast cancer

Background: globally, breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death in women. The surgical management of patients with early stage operable breast cancer is the main step of treatment and addresses both the primary tumor and regional lymphatics. Objectives: this study aims at highlighting the role of preoperative dynamic contrast enhanced breast MRI in early stage breast cancer and its impact on surgical management. Patients and Methods: this study was carried out over the period from March 2015 to October 2017 in Radiodiagnosis Department of Mansoura University Hospitals and Nasser Institute. The study was conducted on 29 female their ages ranging from 30 to 59 years old the study was approved by our Institution's Ethics Committee, and all patients gave their informed consent before inclusion in the study. Results: in our study, MRI was requested for different causes varying between dense breast which may obscure lesions (51.7%), multifocal lobular carcinoma (13.7%), exclude multicentric lesion (10. 3%) and in (24%) of patients MRI was requested as preoperative routine check. In our study, we found that in 10 patients (34.5%), MRI revealed additional lesions that were not seen on conventional imaging by mammography and ultrasound.Six lesions (20.7%) of those additional occult lesions were identified as malignant and all were ipsilateral. Our study reported that six patients (20. 7%) who had unsuspected abnormalities identified on MRI had changes in treatment based on MRI findings. Conclusion: the results of this study confirm previous reports that preoperative MRI of the breast alters clinical management and detects otherwise occult carcinoma in a substantial number of patients with early breast cancer

Recent predictive parameters for successful weaning from mechanical ventilation in critically Ill patients

Background: Removal of patients from mechanical ventilation (MV) has been termed liberation, discontinuation, withdrawal and most commonly weaning. Weaning covers the entire process of liberating the patient from mechanical support and from the endotracheal tube. Although weaning from MV is successful in most cases, the first attempt fails in 20% of patients. In addition, weaning accounts for over 40% of the total MV time, the proportion varying in function of the etiology of respiratory failure. Objective: The aim of this study was to evaluate the recent protocols of successful weaning from mechanical ventilation of critically ill patients, depending on central venous oxygen saturation, ultrasonographic assessment of diaphragmatic movement, and serial arterial blood gases to assess failure rate 48 hours after weaning. Patients and methods: This prospective randomized study included a total of 90 mechanically ventilated Egyptian patients of both sexes, ASA (I-II) attending at least for 48 hours at intensive care unit, AlAzhar University Hospitals. The included subjects were divided into three groups depending on method of monitoring; group A: serial arterial blood gases, group B: Central venous oxygen saturation and group C: Ultrasonographic assessment of diaphragmatic movement pre and post spontaneous breathing trial. All patients were subjected to daily monitoring of the following weaning parameters: static and dynamic compliances and inspiratory resistance, intrinsic positive end expiratory pressure (Auto PEEP) and Maximum inspiratory pressure (MIP). Results: There is highly statistically significant difference between patients as regard weaning outcome. As the group depended on normal ultrasonographic assessment of diaphragmatic movement, had the largest number of patients with successful weaning. Conclusion: Normal ultrasonographic assessment of diaphragmatic movement proved to be the most important criteria for successful weaning from mechanical ventilation

Assessment of musculoskeletal ultrasound guided injection of the new regenerative medicine techniques (neural prolotherapy and platelet rich plasma) impact versus well established techniques (steroid injection) in cases of carpal tunnel syndrome secondary to rheumatoid arthritis

Background: Rheumatoid arthritis is a systemic rheumatic disease characterized by symmetrical, often erosive and deforming poly-arthritis with extra-articular manifestations in 10­20% of patients, especially those with high titers of rheumatoid factor. Extra articular pathology includes bursitis, tendonitis and neuritis, which results from entrapment, nerve ischemia due to vasculitis or drugs used to treat this condition. Carpal tunnel syndrome is the most common compression neuropathy associated with rheumatoid arthritis. Aim of the Work: To evaluate the efficacy of Neural Prolotherapy and Platelet Rich Plasma in treatment of carpal tunnel syndrome secondary to rheumatoid arthritis. Patients and Methods: Ninety patients with Rheumatoid Arthritis (RA) that were all fulfilling the 2016 ACR/EULAR classification criteria for RA. All were over the age of sixteen years at time of diagnosis, complaining of burning pain or paresthesia in the median nerve distribution of the hand. They were recruited from Rheumatology and Rehabilitation Department at Al-Hussein and Sayed Galal University Hospitals during the period from December 2018 to July 2019. Results: Neural Prolotherapy and Platelet Rich Plasma (PRP) have improved all measured parameters like visual analogue scale (VAS), nerve conduction studies and neuromuscular ultrasonography parameters in carpal tunnel syndrome secondary to rheumatoid arthritis. Conclusion: Neural Prolotherapy and Platelet Rich Plasma proved to be effective treatments of carpal tunnel syndrome secondary to rheumatoid arthritis

Conclusions: This study shows that proximal fibular osteotomy (PFO), a new surgery, can effectively relieves pain and improves knee function in patients with medial compartment osteoarthritis

Significance of neuropilin-1 expression, ceruloplasmin oxidase and copper in egyptian children with b-lineage acute lymphoblastic leukemia

Background: Neuropilins are transmembrane glycoproteins that act as receptors for vascular endothelial growth factors (VEGF) and are involved in the process of tumor angiogenesis. Ceruloplasmin is a member of the multi copper oxidase family. It has antioxidant properties that play a central role in protection of the body against advanced oxidation protein products.Objective: This study was aimed to assess the expression of Neuropilin-1(NRP-1) on blasts of B-lineage precursor lymphoblastic leukemia (ALL) to be used in the diagnostic panel of this disease. We also aimed to assess the alteration of the levels of ceruloplasmin oxidase and copper as a compensatory mechanism to minimize the effects of reactive oxygen species resulting from leukemias.Subjects and Methods: This study was conducted on 40 children with newly diagnosed B-lineage precursor lymphoblastic leukemia. 40 age-matched controls were enrolled to serve as control. The expression of NRP-1 on peripheral blood samples was evaluated by flow cytometry as the proportion of positive cells expressing the marker. Ceruloplasmin oxidase and copper levels were assessed by immunoturbidimetric assay.Results: There was highly significant increase in the proportion of positivity of NRP -1 in patients compared with control group (P<0.001) Ceruloplasmin oxidase and copper levels were also higher in patients compared with control group (P<0.001).Conclusions: It could be concluded that NRP-1 is a valuable marker for diagnosis of B-lineage ALL. There is an increase in the levels of ceruloplasmin oxidase and copper which at the time of diagnosis of B-ALL

The effect of ketamine as adjuvant in ultrasonic guided Supraclavicular brachial plexus block

Background: in orthopedic procedures more blood is lost from raw bone and muscle surface than from identifiable blood vessels. Moderate hypotensive anesthesia was found to significantly decrease the average blood loss by nearly 40%, reduce the need for transfusion by 45% and shorten the average operating time by nearly 10%. Objective: The aim of the current study was to compare magnesium sulphate and dexmedetomidine with nitroglycerin as regard hypotensive effect as primary outcome, volume of blood loss, blood substitution and pattern of recovery as secondary outcome during lumbar spine surgery. Patients and Methods: This prospective, controlled, comperative, randomized, double blind study included a total of ninty patients aged 21-50 years of both sex, ASA I-II scheduled for elective lumber spine surgery, attending at Department of Orthopedic, AL-Azher university Hospital in Assuit as single center study. Patients have received either dexmedetomidine, magnesium sulfate or nitroglycerine. Results: There were highly significant difference (P <0.000) with duration of surgery between different study groups with duration of surgery shortest in dexmedetomidine group followed by magnesium sulfate group and then nitroglycerine group. There were highly significant differences between different study groups with fluid maintenance with higher volume in nitroglycerine group then magnesium sulfate group and then dexmedetomidine group. There were highly significant differences (P <0.000) with systolic blood pressure between study groups at A1 and hypotensive agent discontinuation with lowest systolic blood pressure in dexmedetomidine group followed by magnesium sulfate group and then nitroglycerine group. Conclusion: nitroglycerine, magnesium sulfate and dexmedetomidine could induce hypotension, but dexmedetomidine showed more favorable hemodynamic profile as regard blood pressure and heart rate

Role of external fixator combined with t-plate internal fixation in the treatment of comminuted distal radial fractures

Background: A technique of external fixator combined with T-plate internal fixation for intra-articular fractures of the distal radius is based on the finding that the separate t-plate fixation do not give complete stability to the fracture. However, if it is combined externally by external fixator, you get a solid synthesis of the fractured radius. This enables early mobilization of the wrist without the use of plaster cast. Objective: The aim of the study was to evaluate the results of external fixator combined with palmar T-plate internal fixation for the treatment of comminuted distal radial fractures. Patients and methods: This was a prospective study that was conducted on 20 patients. Patients were treated by the external fixator combined with T-plate internal fixation. All patients were attending to the Emergency Department and Outpatient Clinic of Orthopedic Surgery Department in Tanta University Hospitals. Results: Patients had excellent range of motion, normal ROM of the arm, shoulder and hand. No significant differences in the radiographic parameters were detected between fracture fixation and fracture healing. Complications were few. At final follow-up evaluations, patients had well to excellent results with respect to range of motion scores. Stable fixation allowed starting active and passive motion of the wrist without compromising postoperative alignment. The poor results in this case were due to late intervention, osteoporosis due to old age and poor general condition of the patient, which resulted in incomplete union. Conclusion: External fixator combined with T-plate internal fixation is an efficacious treatment option for intra-articular distal radius fractures with excellent long-term results

Randomized comparative study between direct and indirect tibial revascularization in management of critical limb ischemia

Background: Hepatitis C virus (HCV) is a blood born virus that is considered a major cause of chronic liver disease and hepatocellular carcinoma (HCC) worldwide. HCV is thought to induce HCC either indirectly or directly by the effect of its viral proteins on different host cell proteins and signaling pathways. Objective: The aim of the study was to characterize the type of response to different HCV antigens, quantify HCV viral load, transforming growth factor- beta and miRNA 122 in patients with newly diagnosed Hepatocellular Carcinoma. Patients and methods: This study was done on three groups: the first group consisted of 40 newly discovered hepatocellular carcinoma patients with HCV infection. The second group consisted of twenty HCV infected patients with other types of cancer (other than HCC). The third group consisted of 20 healthy individuals served as a control group. Serum was separated for detection of the four parameters. Results: TGF-ß showed a very weak negative correlation with the miRNA 122 serum levels that is statistically non-significant. Results also showed that miRNA 122 may not be useful in differentiating between liver cirrhosis from HCC patients and it is associated with the severity of the disease rather than the viremia count. Conclusion: Study showed no correlation between the four investigated parameters (HCV antigens, HCV viral load, TGF-ß- serum levels of miRNA 122) in an attempt for early diagnosis of HCV induced HCC

Benign effects of Helicobacter pylori in gastric mucosa among symptomatic Sudanese patients

Infection with Helicobacter pylori is a worldwide problem. It plays an important role in gastric malignancies.The pathogenesis of gastric malignancies involves multistep progression changes in gastric mucosa and the Helicobacter pylori infections is the first step in most of cases.Aim:The aims of this study were to clarify the benign changes in gastric mucosa after Helicobacter pylori infection;to evaluate the endoscopic and histological patterns of infection and to correlate endoscopic findingwith histopathological parameters.Materials and Methods:A descriptive, retrospective study was done in Soba University Hospital between January 2009 - February2013. Paraffin-embedded blocks, Giemsa and Haematoxylin and Eosin-stained slides, were obtained from 50 cases of Helicobacter pylori-associated chronic gastritis and examined under light microscopy. The clinical information and endoscopy findings were obtained from the records. The data was analyzed using Statistical Package for Social Sciences Software.Results:The most common affected age group was between 40-60 years. The prevalence of infection was equal in males and females. The commonest endoscopic finding was inflammation of gastric mucosa. Most patients presented with moderate degree of colonization; 62% of patients presented with a severe degree of chronic inflammation. There was a significant statistical correlation between the degree of Helicobacter pylori colonization and the degree of chronic inflammation (p<0.05). Most patients presented with severe degree of active gastritis. A significant correlation was found between the degree of chronic inflammation and degree of activity. The prevalence of lymphoid follicles in a single biopsy specimen from antral mucosa was 36%.The dysplasia was seen in 12%; eosinophilia 8%; atrophy 8% and intestinal metaplasia in 6% of the cases.No significant correlation was found between the endoscopic findings and histological findings.Conclusion:Helicobacter pylori infection causes chronic active gastritis and it has a role in the development of lymphoid follicles, intestinal metaplasia, atrophy and dysplasia

Evaluation of serum interleukin-34, as a marker of disease activity in systemic lupus erythematosus and rheumatoid arthritis patients

Aim of the work: To evaluate the role of IL-34 in the pathogenesis of SLE and RA and to assess its role as a biomarker of disease activity. Subjects and methods: This study was carried out on 29 patients with SLE, 29 patients with RA, and 29 healthy control subjects. SLE disease activity was measured by systemic lupus erythematosus disease activity index (SLEDAI). RA disease activity was measured by 28-joint disease activity score (DAS-28). Serum IL-34 was measured by enzyme-linked immunosorbent assay (ELISA) . Results: There was highly significant elevation in IL-34 level in SLE and RA when compared to control group (p<0.001). IL34 level did not differ significantly between SLE and RA groups (p˃ 0.05). There was a significant positive correlation between IL-34 level and SLEDAI in SLE patients as well DAS 28 score in RA patients. The highest level was detected in patients with high disease activity. There was statistically significant correlation between IL-34 levels and ESR, CRP, and anti-ds DNA antibodies but inversely correlated with C3 in SLE patients. There was also statistically significant correlation between IL-34 levels and ESR, CRP RF, and anti CCP antibodies in RA patients. Conclusion: IL-34 could be useful marker for disease activity in SLE and RA

Comparison impact of conventional versus conformal radiotherapy techniques on thyroid in breast cancer irradiation

Introduction: Adjuvant radiotherapy is considered one of treatment options for treatment of locally advanced breast cancer. Thyroid gland is not considered an organ at risk in supraclavicular (SC) nodal radiation therapy (RT) for breast cancer. Objectives: Comparison the impact of 2 different RT techniques on thyroid gland; group (I) conventional two-dimensional radiotherapy of SC node and Group (II) three-dimensional conformal radiation therapy (3DCRT) planning of SC node. Method: Twenty (20) patients with breast cancer received SC RT, with evaluation of thyroid functions in both groups, including thyroid stimulating hormone and free thyroxine prior to RT and 3, 6, 9, 12, 18 and 24 months after RT. Based on each patient's dose volume histogram (DVH),total volume of thyroid and mean radiation dose of the thyroid which received radiation doses 10-50 Gy (V10-V50) were considered for statistical analysis. The median follow-up time was 20 months (range, 12-30 months). Results: of 20 patients, 5 (20%) were diagnosed with hypothyroidism (HT), 4 group (II) and 1 group (I). The median time to the development of HT was 9 months. SC node V50 in group I was lower than average in group II (Average: 2.06% versus 55.38% p<0.001).Thyroid V20 in group I was lower than average in group II (Average: 37.65% versus 50.47%, p<0.001) mean TSH in group I was lower than mean in group II (Average: 1.60 IU/L versus 3.08 IU/L, p=0.043). Conclusion: Conformal supraclavicular RT in patients with breast cancer appear to amplify the risk of HT more than conventional, however conformal radiotherapy is better than conventional radiotherapy in locoregional control
