    Postoperative herniation of the stomach into potential spaces is a rare but serious complication of Nissen fundoplication. We report a 55-year-old female who presented with persistent vomiting shortly following laparoscopic Nissen fundoplication. At laparotomy, the anterior wall of the stomach was noted to be herniating into a congenital space behind the diaphragm. Anterior gastropexy was performed following the reduction of the herniating gastric segment. A high index of suspicion followed by aggressive and timely intervention is necessary to diagnose and manage postoperative gastric herniation and reduce the subsequent morbidity and mortality

    Gaucher disease is the autosomally recessively inherited deficiency of the lysosomal enzyme glucocerebrosidase. Increasing storage of glucocerebrosides leads to a multisystem disease, the prevalence of which is about 1 : 40,000 in central Europe and up to 1 : 2,000 in some other countries (e. g. Israel). The acute and chronic neuronopathic forms of the disease (formerly defined as Gaucher types 2 and 3) account for only 5 to 10% of all Gaucher patients in Central Europe and Germany and are thus less frequent than the nonneuronopathic disease (formerly defined as Gaucher type 1). Gaucher's disease is usually associated with splenoand hepatomegaly, fatigue, skeletal complications, and several corresponding hematological and laboratory abnormalities. In 5 to 10% of the patients there are also central nervous symptoms such as myoclonic seizures, oculomotoric apraxia and a slight mental retardation. Recent epidemiological data indicate that only 10 to 20% of all Gaucher patients are correctly diagnosed (and treated) in Germany. The diagnosis today can be done in all patients by noninvasive methods, i. e. determination of the glucocerebrosidase activity in peripheral leukocytes and of the genetic defect, in this research the PCR technique was used to analyze the mutation in glucocerebrosidases gene (G ---C). Key words: Gaucher disease (GD), lysosomal storage disorder (LSD),lysosomal enzyme glucocerebrosidase, PCR, Mutation

    Glutathione for food and health applications with emphasis on extraction, identification, and quantification methods: a review

    Get PDF
    Glutathione is a naturally occurring compound that plays a crucial role in the cellular response to oxidative stress through its ability to quench free radicals, thus mitigating the risk of potential damage, including cell death. While glutathione is endogenously present in different plants and animal cells, their concentration varies considerably. The alteration in glutathione homeostasis can be used as a potential marker for human diseases. In the case of the depletion of endogenous glutathione, exogenous sources can be used to replenish the pool. To this end, both natural and synthetic glutathione can be used. However, the health benefit of glutathione from natural sources derived from fruits and vegetables is still debated. There is increasingly growing evidence of the potential health benefits of glutathione in different diseases; however, the determination and in situ quantification of endogenously produced glutathione remains a major challenge. For this reason, it has been difficult to understand the bioprocessing of exogenously delivered glutathione in vivo. The development of an in situ technique will also aid in the routine monitoring of glutathione as a biomarker for different oxidative stress-mediated diseases. Furthermore, an understanding of the in vivo bioprocessing of exogenously delivered glutathione will also aid the food industry both towards improving the longevity and profile of food products and the development of glutathione delivery products for long-term societal health benefits. In this review, we surveyed the natural plant-derived sources of glutathione, the identification and quantification of extracted glutathione from these sources, and the role of glutathione in the food industry and its effect on human health.info:eu-repo/semantics/publishedVersio

    This study aimed to isolate and identify the Bacillus licheniformis bacteria that produces the enzyme collagenase. Due to the selective nature of this enzyme in breaking down and degrading collagen, it was used to tenderize aged buffalo meat. The bacterial isolates were screened using a selective medium and then grown on collagen-agar medium to identify enzyme-producing isolates. Thirteen enzyme-producing isolates were obtained based on the formation of a transparent corona around the colony. Biochemical assessments of the bacterial isolates were carried out using the ABIS online program. The isolates BL1–BL9, BL12 and BL13 were found to be related to B. licheniformis with a percentage match of 98%, while BL10 and BL11 were related to Bacillus pumilus and Bacillus subtilis with a percentage match of 95% and 95.3%, respectively. The enzyme activity of the isolates varied, with the highest activity reaching 200.71 units.ml-1 for isolate BL12. The enzyme of this isolate was chosen to complete the other tests. The optimal time required to obtain the highest enzymatic activity was found to be 20 h, which amounted to 210.25 units.ml-1, with a specific activity of 135.64 units.ml-1. The enzyme was partially purified using ammonium sulphate at a saturation rate of 20–70% as it showed an enzymatic activity and specificity of 355.81 units.ml-1 and a specific activity of 423.58 units.ml-1. Partially purified collagenase was used to tenderize aged buffalo meat. The results showed that treating aged buffalo meat with the enzyme solution for different immersion durations improved the pH, water-holding capacity (WHC) and cooking yield, with an increase in the concentration of hydroxyproline and a significant percentage of soluble collagen; the treated samples showed the best properties with a 60-min immersion duration

    RECHALLENGING TREATMENT PLAN FOR MULTIDRUG-RESISTANT TUBERCULOSIS IN DIABETIC PATIENT: A CASE REPORT

    Get PDF
    Multidrug-resistant tuberculosis (MDR-TB) currently considers as the biggest issue and its subcategory, rifampicin-resistant TB (RR-TB). MDR-TB is defined as a resistant to isoniazid (H) and rifampicin (R), while the latter is resistant to rifampicin (R) only. Poorly controlled diabetes mellitus increases the risk of TB and leads to poor TB treatment outcomes as well it is consider potentially threating TB control. Difference in patients’ response and side effect developments toward anti-TB (ATB) medications requires rechallenging procedure that can be complicated at times. The management of MDR-TB can be complicated, especially, when the patient cannot tolerate the short regimen. Difference in patients’ response and side effect developments toward ATB medications requires rechallenging procedure which can have prolonged treatment time, hospital stay, and make patients exposed to hospital-acquired infection. This challenges and obstacles, however, could be prevented earlier by having strong DOTS strategy to prevent the development of resistance and reactivation of TB

These permissions are granted for the duration of the World Health Organization (WHO) declaration of COVID-19 as a global pandemicBackground This study aimed to determine the incidence of new onset hepatic steatosis after neoadjuvant chemotherapy for pancreatic cancer and its impact on outcomes after pancreatoduodenectomy. Methods Retrospective review identified patients who received neoadjuvant chemotherapy for pancreatic adenocarcinoma and underwent pancreatoduodenectomy from 2013 to 2018. Preoperative computed tomography scans were evaluated for the development of hepatic steatosis after neoadjuvant chemotherapy. Hypoattenuation included liver attenuation greater than or equal to 10 Hounsfield units less than tissue density of spleen on noncontrast computed tomography and greater than or equal to 20 Hounsfield units less on contrast-enhanced computed tomography. Results One hundred forty-nine patients received neoadjuvant chemotherapy for a median of 5 cycles (interquartile range (IQR), 4–6). FOLFIRINOX was the regimen in 78% of patients. Hepatic steatosis developed in 36 (24%) patients. The median time from neoadjuvant chemotherapy completion to pancreatoduodenectomy was 40 days (IQR, 29–51). Preoperative biliary stenting was performed in 126 (86%) patients. Neoadjuvant radiotherapy was delivered to 23 (15%) patients. Female gender, obesity, and prolonged exposure to chemotherapy were identified as risk factors for chemotherapy-associated hepatic steatosis. Compared with control patients without neoadjuvant chemotherapy-associated hepatic steatosis, patients developing steatosis had similar rates of postoperative pancreatic fistula (8% (control) vs. 4%, p = 0.3), delayed gastric emptying (8% vs. 14%, p = 0.4), and major morbidity (11% vs. 15%, p = 0.6). Ninety-day mortality was similar between groups (8% vs. 2%, p = 0.08). Conclusion Hepatic steatosis developed in 24% of patients who received neoadjuvant chemotherapy but was not associated with increased morbidity or mortality after pancreatoduodenectomy
