Liver biopsies were evaluated for fibrosis, qualitatively, by Ishak score and quantitatively by fibrosis area fraction(FAF) using digital image analysis(morphometry). LSM was correlated with fibrosis and other studied variables using spearman correlation. A stepwise multiple regression analysis was alsoperformed to examine independent factors associated with LSM. Different cut-off values of LSM were calculated for predicting individual fibrosis stages using receiveroperating characteristic curve. Cut-off values with optimal clinical performance(optimal sensitivity and specificity simultaneously) were selected.RESULTS: The majority of HCV group had minimal activity(80%) and no/mild fibrosis(72%). On the other hand, the majority of AIH group had mild to moderate activity(70%) and moderate to severe fibrosis(95%) and all Wilson disease group had mild to moderate activity(100%) and moderate to severe fibrosis(100%). LSM correlated significantly with both FAF and Ishak scores and the correlation appeared better with the latter(r = 0.839 vs 0.879, P < 0.0001 for both). LSM discriminated individual stages of fibrosis with high performance. Sensitivity ranged from 81.4% to 100% and specificity ranged from 75.0% to 97.2%. When we compared LSM values for the same stage of fibrosis, they varied according to the different etiologies. Higher values were in AIH(16.15 ± 7.23 k Pa) compared to Wilson disease(8.30 ± 0.84 k Pa) and HCV groups(7.43 ± 1.73 k Pa). Multiple regression analysis revealed that Ishak fibrosis stage was the only independent variable associated with higher LSM(P < 0.0001).CONCLUSION: TE appears reliable in distinguishing different stages of liver fibrosis in children. However, its values vary according to the disease type. For that, a disease-specific estimation of cut-off values for fibrosis staging is worthy.展开更多

METHODS:Morphological investigations were conducted on biopsy material obtained from 40 children,aged 3-16 years with chronic hepatitis B. The stage of fibrosis was assessed histologically using the arbitrary semiquantitative numerical scoring system proposed by Ishak et al. The material for ultrastructural investigation was fixed in glutaraldehyde and paraformaldehyde and processed for transmission-electron microscopic analysis. RESULTS:Ultrastructural examination of biopsy specimens obtained from children with chronic hepatitis B showed the presence of two types of oval cells,the hepatic progenitor cells and intermediate hepatic-like cells. These cells were present in the parenchyma and were seen most commonly in areas of intense periportal fibrosis (at least stage 2 according to Ishak et al) and in the vicinity of the limiting plate of the lobule. The activated nonparenchymal hepatic cells,i.e. transformed hepatic stellate cells and Kupffer cells were seen in close proximity to the intermediate hepatic-like cells. CONCLUSION:We found a distinct relationship between the prevalence of oval cells (hepatic progenitor cells and intermediate hepatocyte-like cells) and fibrosis stage in pediatric patients with chronic hepatitis B.展开更多

Although several oxidants and antioxidants are likely to be involved, alterations in only limited parameters have been studied. Objective: In this study an attempt has been made to study the oxidant-antioxidant imbalance by investigating changes in a wide range of oxidants and antioxidants in the blood. Methods: Blood samples were obtained from 39 chronic allergic rhinitis patients (males 24, females 15), aged 20-70 (mean age 36.33 ± 2.03) years and 53 individuals (36 males, 17 females);aged 24 to 64 (mean age 45.42 ± 1.36) years. Duration of allergic rhinitis was 1.77 ± 0.237 years. In the study group, nasal symptoms were scored and the results were recorded. The patients were classified as having perennial Allergic rhinitis (PAR) if they had had at least 2 rhinitis symptoms (sneezing, rhinorrhea, nasal obstruction, itching) for at least 6 months a year in the previous 2 years and if they had a positive skin prick test response to at least 1 clinically significant perennial allergen (e.g., house dust mites, molds, cockroach, cockroach excrement grass and tree pollen, cat and dog epithelia and molds, or animal dander). They had no other allergic diseases except persistent allergic rhinitis diagnosed by the physical and history examination. Erythrocyte lipid peroxidation, erythrocyte antioxidants viz., glutathione, glutathione reductase, superoxide dismutase, catalase and plasma antioxidants viz., ceruloplasmin, glutathione-S-transferase, vitamin C, total antioxidant activity were estimated in the above two groups. Results: Erythrocyte lipid peroxidation (0 hour, p < 0.01) and superoxide dismutase (p < 0.01) were significantly higher, whereas plasma vitamin C (p < 0.001), ceruloplasmin (p < 0.05) and total antioxidant activity (p < 0.001) were significantly lower in chronic allergic rhinitis patients when compared to controls. Plasma Glutathione S transferase and erythrocyte catalase, glutathione, and glutathione reductase remained unchanged from normal subjects. Conclusion: The changes in different parameters indicate an imbalance in the oxidant and antioxidant status in chronic allergic rhinitis patients. Further studies are required to investigate the potential for antioxidant supplements to be used as routine therapy in chronic allergic rhinitis patients. Capsule summery: The study shows that the body is trying to cope for the oxidative stress by altering the enzyme levels. But external supplement may also be required as the total antioxidant levels are very much depleted.展开更多

Currently, Morocco provides several therapeutic tools for cancer, among them chemotherapy, surgery and radiotherapy. In Morocco, there is not enough published data on the use of alternative medicine in pediatric oncology. Owing to the increased interest and lack of data on this practice, we conducted this study. It aims to evaluate the uptake, the types of therapies used, the factors influencing, the reasons for this choice and the cost of AM used by patients. An investigation through a questionnaire was carried out on thirty-four children following for cancer within the pediatric hematology and oncology department (PHO) of Marrakech. The survey was conducted over a period of one month and a half between July 25 and September 5, 2022. Data were collected through a questionnaire. From the medical files, we collected data regarding type of cancer, date of admission to PHO department and the treatment received. We asked about the type of AM used: herbs, honey, spiritual AM, zamzam water (water from a “sacred” source in Mecca). Using alternative therapies is a common practice in pediatric oncology with various reasons, among them, the declining socioeconomic level, the diversity, the cultural background, the psychological and the functional status of patients and sometimes the dissatisfaction with conventional medicine.展开更多

This study focused on understanding COVID-19’s clinical presentation, disease progression, and outcomes among hospitalized pediatric patients. Additionally, it sought to investigate the impact of concurrent chronic medical conditions on disease severity. Methods: Conducted retrospectively between September 2020 and December 2021, this study observed pediatric patients (below 18 years) hospitalized with confirmed COVID-19 at an Irbid, Jordan tertiary healthcare center. Patients meeting inclusion criteria, including a positive nasal swab PCR test and hospitalization need, were analyzed. Epidemiological and clinical data were collected and segregated into two groups (A and B) based on the presence of chronic conditions. Comparative analysis encompassed presentation, disease trajectory, and outcomes between these groups. Results: Among 451 tested positive patients, 112 were included in the study. Significant differences emerged between the two pediatric groups hospitalized for COVID-19. Those with concurrent chronic illnesses exhibited heightened symptom severity—fever, dyspnea, fatigue—and a higher incidence of abnormal chest radiographs, often requiring intensive care and experiencing elevated mortality rates. Conclusion: This study underscores the criticality of prioritizing COVID-19 management strategies for pediatric patients with pre-existing chronic medical conditions. The findings highlight the increased vulnerability and poorer outcomes experienced by this subgroup, emphasizing the necessity for tailored interventions and focused care approaches.展开更多

文摘Background: Allergic rhinitis is an inflammatory disorder of the upper airways. Although several oxidants and antioxidants are likely to be involved, alterations in only limited parameters have been studied. Objective: In this study an attempt has been made to study the oxidant-antioxidant imbalance by investigating changes in a wide range of oxidants and antioxidants in the blood. Methods: Blood samples were obtained from 39 chronic allergic rhinitis patients (males 24, females 15), aged 20-70 (mean age 36.33 ± 2.03) years and 53 individuals (36 males, 17 females);aged 24 to 64 (mean age 45.42 ± 1.36) years. Duration of allergic rhinitis was 1.77 ± 0.237 years. In the study group, nasal symptoms were scored and the results were recorded. The patients were classified as having perennial Allergic rhinitis (PAR) if they had had at least 2 rhinitis symptoms (sneezing, rhinorrhea, nasal obstruction, itching) for at least 6 months a year in the previous 2 years and if they had a positive skin prick test response to at least 1 clinically significant perennial allergen (e.g., house dust mites, molds, cockroach, cockroach excrement grass and tree pollen, cat and dog epithelia and molds, or animal dander). They had no other allergic diseases except persistent allergic rhinitis diagnosed by the physical and history examination. Erythrocyte lipid peroxidation, erythrocyte antioxidants viz., glutathione, glutathione reductase, superoxide dismutase, catalase and plasma antioxidants viz., ceruloplasmin, glutathione-S-transferase, vitamin C, total antioxidant activity were estimated in the above two groups. Results: Erythrocyte lipid peroxidation (0 hour, p < 0.01) and superoxide dismutase (p < 0.01) were significantly higher, whereas plasma vitamin C (p < 0.001), ceruloplasmin (p < 0.05) and total antioxidant activity (p < 0.001) were significantly lower in chronic allergic rhinitis patients when compared to controls. Plasma Glutathione S transferase and erythrocyte catalase, glutathione, and glutathione reductase remained unchanged from normal subjects. Conclusion: The changes in different parameters indicate an imbalance in the oxidant and antioxidant status in chronic allergic rhinitis patients. Further studies are required to investigate the potential for antioxidant supplements to be used as routine therapy in chronic allergic rhinitis patients. Capsule summery: The study shows that the body is trying to cope for the oxidative stress by altering the enzyme levels. But external supplement may also be required as the total antioxidant levels are very much depleted.
文摘Chronic rhinosinusitis and allergic rhinitis are chronic inflammatory diseases that affect the mucous membrane of the nose and paranasal sinuses. These diseases are characterized by recruitment of inflammatory cells to the upper airway. For this to take place a complex interaction between inflammatory cells and the cytokines/chemokines(ligand) liberated at the site of inflammation is involved in a process termed chemotaxis or directed cell migration against concentration gradient of the ligand. This entails signal transduction through the cell surface receptor resulting in cellular functional response and directed migration. In this editorial the novel role of CX3CR1 receptor in the immunopathology of chronic inflammation of the nose and paranasal sinuses will be explored with its potential role as therapeutic target in chronic nasal inflammation.

文摘Scientific research has brought about enormous national advancements in cancer management. Currently, Morocco provides several therapeutic tools for cancer, among them chemotherapy, surgery and radiotherapy. In Morocco, there is not enough published data on the use of alternative medicine in pediatric oncology. Owing to the increased interest and lack of data on this practice, we conducted this study. It aims to evaluate the uptake, the types of therapies used, the factors influencing, the reasons for this choice and the cost of AM used by patients. An investigation through a questionnaire was carried out on thirty-four children following for cancer within the pediatric hematology and oncology department (PHO) of Marrakech. The survey was conducted over a period of one month and a half between July 25 and September 5, 2022. Data were collected through a questionnaire. From the medical files, we collected data regarding type of cancer, date of admission to PHO department and the treatment received. We asked about the type of AM used: herbs, honey, spiritual AM, zamzam water (water from a “sacred” source in Mecca). Using alternative therapies is a common practice in pediatric oncology with various reasons, among them, the declining socioeconomic level, the diversity, the cultural background, the psychological and the functional status of patients and sometimes the dissatisfaction with conventional medicine.
文摘BACKGROUND This study evaluated the safety and effectiveness of endoscopic retrograde cholangiopancreatography(ERCP)in pediatric patients with biliary and pancreatic diseases.A retrospective analysis was conducted on 57 ERCP procedures performed in 41 children,primarily for treating pancreatic diseases.The overall success rate was 91.2%,with no major complications observed.Post-ERCP pancreatitis(PEP)occurred in 8.8%of cases.Follow-up examinations over one year showed no recurrence of biliary or pancreatic diseases.Notably,endoscopic treatment led to a significant increase in body mass index(BMI).These findings demonstrate the valuable role of ERCP in managing such conditions.AIM To evaluate the safety and efficacy of ERCP for the management of biliary and pancreatic diseases in pediatric patients.METHODS We conducted a retrospective analysis of data from children aged 1-18 years who underwent ERCP for biliary and pancreatic diseases at Beijing Children’s Hospital between January 2021 and December 2022.The collected data included procedure time,endoscopic treatment,success rate,and postoperative complications.RESULTS Forty-one children underwent 57 ERCP procedures,including 14 with biliary duct disease and 27 with pancreatic disease.The mean age of the patients was 7.48±3.48 years.Biliary duct-related treatments were performed 18 times,and pancreatic disease treatments were performed 39 times.ERCP was primarily used to treat pediatric pancreatic diseases[68.4%(39/57)of the procedures].The overall success rate was 91.2%(52/57 patients).PEP was noted in five patients(8.8%,5/57),and no instances of bleeding,perforation,or cholangitis were observed.The patients were followed up for over one year,and no recurrence of biliary or pancreatic diseases was detected.Importantly,BMI significantly increased after endoscopic treatment compared to that before treatment(P=0.001).CONCLUSION The high success rate and lack of major complications support the valuable role of ERCP in the management of pediatric biliary and pancreatic diseases in the pediatric population.
文摘Background: The COVID-19 pandemic emerged unexpectedly, impacting millions worldwide and, though waning in many regions, remains a significant concern. This study focused on understanding COVID-19’s clinical presentation, disease progression, and outcomes among hospitalized pediatric patients. Additionally, it sought to investigate the impact of concurrent chronic medical conditions on disease severity. Methods: Conducted retrospectively between September 2020 and December 2021, this study observed pediatric patients (below 18 years) hospitalized with confirmed COVID-19 at an Irbid, Jordan tertiary healthcare center. Patients meeting inclusion criteria, including a positive nasal swab PCR test and hospitalization need, were analyzed. Epidemiological and clinical data were collected and segregated into two groups (A and B) based on the presence of chronic conditions. Comparative analysis encompassed presentation, disease trajectory, and outcomes between these groups. Results: Among 451 tested positive patients, 112 were included in the study. Significant differences emerged between the two pediatric groups hospitalized for COVID-19. Those with concurrent chronic illnesses exhibited heightened symptom severity—fever, dyspnea, fatigue—and a higher incidence of abnormal chest radiographs, often requiring intensive care and experiencing elevated mortality rates. Conclusion: This study underscores the criticality of prioritizing COVID-19 management strategies for pediatric patients with pre-existing chronic medical conditions. The findings highlight the increased vulnerability and poorer outcomes experienced by this subgroup, emphasizing the necessity for tailored interventions and focused care approaches.
