Neurólise do tronco celíaco com o uso de agulha única versus agulha dupla no manejo da dor abdominal maligna: estudo randômico controlado

BackgroundComputerized tomography‐guided celiac plexus neurolysis has become almost a safe technique to alleviate abdominal malignancy pain. We compared the single needle technique with changing patients’ position and the double needle technique using posterior anterocrural approach.MethodsIn Double Needles Celiac Neurolysis Group (n = 17), we used two needles posterior anterocrural technique injecting 12.5 mL phenol 10% on each side in prone position. In Single Needle Celiac Neurolysis Group (n = 17), we used single needle posterior anterocrural approach. 25 mL of phenol 10% was injected from left side while patients were in left lateral position then turned to right side. The monitoring parameters were failure block rate and duration of patient positioning, technique time, Visual Analog Scale, complications (hypotension, diarrhea, vomiting, hemorrhage, neurological damage and infection) and rescue analgesia.ResultsThe failure block rate and duration of patient positioning significantly increased in double needles celiac neurolysis vs. single needle celiac neurolysis (30.8% vs. 0.13.8±1.2 vs. 8.9 ± 1; p = 0.046, p ≤ 0.001 respectively). Also, the technique time increased significantly in double needles celiac neurolysis than single needle celiac neurolysis (24.5 ± 5.1 vs. 15.4 ± 1.8; p ≤ 0.001). No significant differences existed as regards visual analogue scale: double needles celiac neurolysis = 2 (0‐5), 2 (0‐4), 3 (0‐6), 3 (2‐6) and single needle celiac neurolysis = 3 (0‐5), 2 (0‐5), 2 (0‐4), 4 (2‐6) after 1 day, 1 week, 1 and 3 months respectively. However, visual analogue scale in each group reduced significantly compared with basal values (p ≤ 0.001). There were no statistically significant differences as regards rescue analgesia and complications (p > 0.05).ConclusionSingle needle celiac neurolysis with changing patients’ position has less failure block rate, less procedure time, shorter duration of patient positioning than double needles celiac neurolysis in abdominal malignancy.     

The influence of polymorphisms in the drug transporter,ABCB1 on the toxicity of glucocorticoids in Saudi children with acute lymphoblastic leukaemia

Background

Glucocorticoids play essential roles in the treatment of childhood acute lymphoblastic leukaemia (ALL); however, treatment with these agents can result in severe side-effects. This study, the first of its kind in a Saudi population, investigates associations of ABCB1 gene polymorphisms (pharmacodynamics and pharmacokinetic) with the development of toxicity and side effects (glucose abnormality, liver toxicity and infection) in a small population of Saudi children with ALL.

Development,implementation, and evaluation of an integrated multidisciplinary Objective Structured Clinical Examination (OSCE) in primary health care settings within limited resources

Background: In ordinary circumstances, objective structured clinical examination (OSCE) is a resource-intensive assessment method. In case of developing and implementing multidisciplinary OSCE, there is no doubt that the cost will be greater.

Aim: Through this study a research project was conducted to develop, implement and evaluate a multidisciplinary OSCE model within limited resources.

Methods: This research project went through the steps of blueprinting, station writing, resources reallocation, implementation and finally evaluation.

Results: The developed model was implemented in the Primary Health Care (PHC) program which is one of the pillars of the Community-Based undergraduate curriculum of the Faculty of Medicine, Suez Canal University (FOM-SCU). Data for evaluation of the implemented OSCE model were derived from two resources. First, feedback of the students and assessors through self-administered questionnaires was obtained. Second, evaluation of the OSCE psychometrics was done. The deliverables of this research project included a set of validated integrated multi-disciplinary and low cost OSCE stations with an estimated reliability index of 0.6.

Conclusion: After having this experience, we have a critical mass of faculty members trained on blueprinting and station writing and a group of trained assessors, facilitators and role players. Also there is a state of awareness among students on how to proceed in this type of OSCE which renders future implementation more feasible.     

Influence of orthodontic appliance type on salivary parameters during treatment

ObjectivesTo evaluate the effect of orthodontic appliances on physicochemical, biochemical, and oxidative stress changes in salivary parameters during treatment.Materials and MethodsA cohort study was conducted with 112 healthy patients. Salivary samples were taken at baseline, 1 month, and 9 months after placement of the orthodontic appliances used in treatment.ResultsA statistically significant difference was observed in certain examined salivary parameters, including enzymes, electrolytes, and oxidative stress markers.ConclusionsThe use of aligners had a lower prevalence of disturbing salivary parameters. Orthodontist must consider these changes to prevent the occurrence of white spot lesions.     

Epilepsy in patients with insulin-dependent diabetes and relation to glutamic acid decarboxylase 65

Objectives:To report if the association of epilepsy in pediatric patients (below the age of 15 years) with Insulin-dependent Diabetes (IDDM) at King Fahad Medical City (KFMC) is higher than the prevalence of epilepsy in the same age group (who have no IDDM) in our community. Consequently, we would determine if there is a relationship between the presence of epilepsy in diabetic children and the presence of positive antiGAD65 antibodies.Methods:This cohort study included 305 pediatric patients below the age of 15 years with Insulin-dependent Diabetes Mellitus (IDDM). They were randomly recruited at the Pediatric Endocrinology Clinic in KFMC. The patients’ caregivers were given a questionnaire between December 2015 till March 2019 to determine the seizure disorder history. There was also a retrospective review of 214 patients’ files for anti-GAD 65 positivity.Results:Our study found a significant relation between the presence of epilepsy in children with IDDM. Therefore, we could confirm the relationship between the existence of epilepsy in children with IDDM and having positive GAD65 antibodies.Conclusion:Our study supports the presence of consistent relation between having IDDM and having epilepsy in children and between the latter and the presence of positive GAD65 antibodies.

Insulin dependent diabetes Mellitus (IDDM) is a common condition in children and adolescents worldwide and so is epilepsy.1,2 Recently, there were increasing reports suggesting a potential association between having IDDM and the occurrence of epilepsy.3 Their association might represent simply a chance to relate their underlying mechanisms. However, the cause-effect relationship is not fully well defined. Literature from other countries have shown the increased prevalence of seizure disorders in this group of patients.4,5 There are scarce studies in the literature investigating IDDM characteristics contributing to having epilepsy, including positive GAD 65 antibodies. In this study that ran in King Fahad Medical City, Riyadh, Kingdom of Saudi Arabia (KSA) we are aiming to determine if the prevalence of epilepsy among 1DDM children under the age of 15 years (in our center) is higher than controls (same age without IDDM), and to check the positivity of anti-GAD 65 amongst those patients in order to find if there is a relationship between epilepsy in children with diabetes and the presence of positive GAD65 Antibodies.     

The possible role of NF-κB1 Rs28362491 polymorphism in male fertility of Egyptian population

Male reproductive impairment is responsible for at least 50% of cases of couple infertility. Nuclear factor-kappa B (NF-κB) has been functionally linked to germ cell apoptosis, which may affect human fertility. The aim of this study was to determine the association between the rs28362491 SNP of the NF-κB1 gene and infertility in Egyptian men. In this case–control study, semen and blood samples of 247 infertile men, constituting the case group, and of 113 fertile healthy men as the control group were analysed. All study participants were genotyped for polymorphism of the NF-κB1 gene (rs28362491) by the polymerase chain reaction—restriction fragment length polymorphism (PCR-RFLP) technique. Heterozygous I/D genotype of the NF-κB1 rs28362491 polymorphism was associated with a significantly lower risk of poor semen quality, including asthenozoospermia, astheno–teratozoospermia, and oligo–astheno–teratozoospermia, when compared to I/I genotype (odds ratio = 0.25, 0.26, 0.18, p < .0005, <.0005, <.0005) respectively. Overall, the presence of the D allele was associated with a significantly decreased risk of poor sperm quality as compared to the I allele (odds ratio = 0.56, 0.64, 0.49, p = .050, .038, .001). In conclusion, these results suggest that heterozygosity of the NF-κB1 gene may play a protecting role against male infertility in Egyptians.
