Hepatoprotective Effects of Silybum marianum
Oxidative stress, lipid peroxidation, and transaminase reactions are some of the mechanisms that can lead to liver dysfunction. A time-dependent study was designed to evaluate the ability of silymarin (SLN) and glycyrrhizin (GLN) in different dosage regimens to lessen oxidative stress in the rats with hepatic injury caused by the hepatotoxin carbon tetrachloride. Wistar male albino rats (n = 60) were randomly assigned to six groups. Group A served as a positive control while groups B, C, D, E, and F received a dose of CCl4 (50% solution of CCl4 in liquid paraffin, 2âmL/kg, intraperitoneally) twice a week to induce hepatic injury. Additionally, the animals received SLN and GLN in different doses for a period of six weeks. CCl4 was found to induce hepatic injury by significantly increasing serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and thiobarbituric acid reactive substances while decreasing total protein and the activities of reduced glutathione, superoxide dismutase, and catalase. Treatment with various doses of SLN and GLN significantly reduced ALT, AST, ALP, and TBARS levels and increased GSH, SOD, and CAT levels. Our findings indicated that SLN and GLN have hepatoprotective effects against oxidative stress of the liver

Early-onset Evans syndrome in a 4-month-old infant: A case report and review of literature
Evans syndrome (ES) is a rare autoimmune disorder characterized by autoimmune hemolytic anemia (AIHA) and immune thrombocytopenic purpura (ITP). We report a case of a 4-month old infant who presented with a history of acute pallor and jaundice. She had no family history of any hematological or autoimmune disorders. Her laboratory investigations revealed a positive direct Coombs test with immunoglobulin G autoantibodies, anemia and thrombocytopenia. She was managed initially by blood transfusion and started on high-dose steroid therapy with marked improvement. Very few cases of ES in infants have been reported in the literature. We concluded that this case report may support the possibility of an early-onset ES among infants <6 months of age
Evaluation of hospital-learning environment for pediatric residency in eastern region of Saudi Arabia
Purpose: No study had been conducted to assess the hospitalsâ environment for learning purposes in multicenter sites in Saudi Arabia. It aims to evaluate the environment of hospitals for learning purposes of pediatric residents. Methods: We applied Postgraduate Hospital Educational Environment Measure (PHEEM) to measure the learning environment at six teaching hospitals in the Eastern Region of Saudi Arabia from September to December 2013. Results: The number of respondents was 104 (86.7%) out of 120 residents and 37 females and 67 male residents have responded. The residentsâ response scored 100 out of 160 maximum score in rating of PHEEM that showed overall learning environment is favorable for training. There were some items in the social support domain suggesting improvements. There was no significant difference between male and female residents. There was a difference among the participant teaching hospitals (p<0.05). Conclusion: The result pointed an overall positive rating. Individual item scores suggested that their social life during residency could be uninspiring. They have the low satisfactory level and they feel racism, and sexual discrimination. Therefore, there is still a room for improvement
Communication skills in pediatric training program: National-based survey of residentsⲠperspectives in Saudi Arabia
Background: Good communication skills and rapport building are considered the cardinal tools for developing a patient-doctor relationship. A positive, healthy competition among different health care organizations in Saudi Arabia underlines an ever increasing emphasis on effective patient-doctor relationship. Despite the numerous guidelines provided and programs available, there is a significant variation in the acceptance and approach to the use of this important tool among pediatric residents in this part of the world. Objective: To determine pediatric residentsⲠattitude toward communication skills, their perception of important communication skills, and their confidence in the use of their communication skills in the performance of their primary duties. Materials and Methods: A cross-sectional study was conducted among all pediatrics trainee residents working in 13 different hospitals in Saudi Arabia. A standardized self-administered questionnaire developed by the Harvard Medical School was used. Results: A total of 297 residents out of all trainees in these centers participated in the data collection. The 283 (95%) residents considered learning communication skills a priority in establishing a good patient-doctor relationship. Thirty four percent reported being very confident with regard to their communication skills. Few residents had the skills, and the confidence to communicate with children with serious diseases, discuss end-of-life issues, and deal with difficult patients and parents. Conclusion: Pediatric residents perceive the importance of communication skills and competencies as crucial components in their training. A proper comprehensive communication skills training should be incorporated into the pediatric resident training curriculum

Anti-Inflammatory Potential of Daturaolone from Datura innoxia Mill.: In Silico, In Vitro and In Vivo Studies
Exploration of leads with therapeutic potential in inflammatory disorders is worth pursuing. In line with this, the isolated natural compound daturaolone from Datura innoxia Mill. was evaluated for its anti-inflammatory potential using in silico, in vitro and in vivo models. Daturaolone follows Lipinski’s drug-likeliness rule with a score of 0.33. Absorption, distribution, metabolism, excretion and toxicity prediction show strong plasma protein binding; gastrointestinal absorption (Caco-2 cells permeability = 34.6 nm/s); no blood–brain barrier penetration; CYP1A2, CYP2C19 and CYP3A4 metabolism; a major metabolic reaction, being aliphatic hydroxylation; no hERG inhibition; and non-carcinogenicity. Predicted molecular targets were mainly inflammatory mediators. Molecular docking depicted H-bonding interaction with nuclear factor kappa beta subunit (NF-κB), cyclooxygenase-2, 5-lipoxygenase, phospholipase A2, serotonin transporter, dopamine receptor D1 and 5-hydroxy tryptamine. Its cytotoxicity (IC50) value in normal lymphocytes was >20 µg/mL as compared to cancer cells (Huh7.5; 17.32 ± 1.43 µg/mL). Daturaolone significantly inhibited NF-κB and nitric oxide production with IC50 values of 1.2 ± 0.8 and 4.51 ± 0.92 µg/mL, respectively. It significantly reduced inflammatory paw edema (81.73 ± 3.16%), heat-induced pain (89.47 ± 9.01% antinociception) and stress-induced depression (68 ± 9.22 s immobility time in tail suspension test). This work suggests a possible anti-inflammatory role of daturaolone; however, detailed mechanistic studies are still necessary to corroborate and extrapolate the findings
