Right perirenal urinoma and urinothorax in an infant after neonatal ablation of posterior urethral valve: A rare complication diagnosed by pleural aspiration and treated with perinephric drainage: a case report.

OBJECTIVE: Urinothorax and urinoma are rare complications of obstructive uropathy. They might occur due to persistent high back pressure on the renal parenchyma. Urinothorax usually arises while the obstruction exists; in contrast to our case, the child presented after being operated on. He had falsely high creatinine before the operation, which was later explained by creatinine recirculation. CLINICAL PRESENTATION AND INTERVENTION: We are reporting an uncommon case of late presentation of ruptured urinoma in a 2-month-old Kuwaiti male. It led to urinothorax/uroperitoneum that caused respiratory distress and was associated with creatinine recirculation, requiring retroperitoneal perinephric catheter insertion. The child had recovered and was discharged home. CONCLUSION: A high index of suspicion is required to diagnose urinothorax, especially in patients with a history of obstructive uropathy. Aspiration of the pleural effusion will guide you to reach the diagnosis. Creatinine recirculation is rarely described in the literature. Having a patient with urinothorax/uroperitoneum should raise the suspicion of falsely elevated creatinine levels.

The effect of Telehealth Antimicrobial Stewardship Program (Tele-ASP) on antimicrobial use in a pediatric intensive care unit: Pre- and post-implementation single center study.

BACKGROUND: Overuse or misuse of antimicrobials is common in pediatric intensive care units (PICU) and may be associated with poor clinical outcomes. Although an antimicrobial stewardship program (ASP) has been found to improve this practice, the required expertise in infectious diseases may be limited in some centers. We aimed to evaluate the effect of telehealth ASP on the rate of PICU antimicrobial use in a center without a local Infectious Diseases consultation service. METHODS: A retrospective cohort study was performed between October 1st, 2018, and October 31st, 2020, in Farwaniya Hospital PICU, a 20-bed unit. All pediatric patients who were admitted to PICU and received systemic antimicrobials during the study period were included and followed until hospital discharge. The ASP team provided weekly prospective audit and feedback on antimicrobial use starting October 8th, 2019. A pediatric infectious diseases specialist joined the ASP rounds remotely. Descriptive analyses and a pre-post intervention comparison of days of therapy (DOT) were used to assess the effectiveness of the ASP intervention. RESULTS: There were 272 and 156 PICU admissions received systemic antimicrobial before and after the initiation of ASP, respectively. Bronchiolitis and pneumonia were the most common admission diagnoses, together compromising 60.7% and 61.2% of cases pre- and post-ASP. The requirement for respiratory support was higher post-ASP (76.5% vs. 91.5%, p < 0.001). Average monthly antimicrobial use decreased from 922 (95%CI 745-1000) to 485 DOT/1000 patient-days (95%CI 246-722, P < 0.05). A decline in DOT was observed across most antibiotic classes, except for ceftriaxone. No effect on the length of PICU stay, length of hospitalization, or mortality was observed. Most (89.7%) ASP recommendations were followed either fully or partially. CONCLUSION: In settings where Infectious Diseases consultation services are unavailable, PICU telehealth ASP can be effectively implemented and associated with significantly reducing antimicrobial use.

Association of the Gelatinase B/Metalloproteinase 9 (MMP-9) Gene Haplotype in Systemic Lupus Erythematosus (SLE) in the Pediatric Egyptian Population.

Permanent systemic inflammation is a defining feature of systemic lupus erythematosus (SLE), which affects multiple organs. Gelatinase B/matrix metalloproteinase-9 (MMP-9) is an essential protease investigated in inflammation that has been linked to SLE. The study's objective was to investigate the relationship between the rs3918249 T/C and rs17576 A/G SNPs in the MMP-9 gene with SLE. The study was conducted with 100 SLE cases and 100 age/sex-matched healthy individuals. TaqManTM SNP was used for genotyping by real time PCR on the Artus Rotor-Gene Qiagen equipment. Haplotypes (TG: OR = 0.226, 95% CI = 0.119−0.429) and (CA: OR = 0.36, 95% CI = 0.2206−0.631), both with a p-value < 0.001 were substantially linked to a lower incidence of SLE. Conversely, the risk of SLE was not associated with the individual SNPs studied. The haplotype analysis was more significant than the SNP analysis and may correlate with the decreased risk of SLE in children and adolescents in Egypt.

Association of CD14 genetic variants and circulating level with systemic lupus erythematosus risk in Egyptian children and adolescents.

Aim: To demonstrate whether sCD14 and CD14 (rs2569190 A/G and rs2569191 C/T) genetic variants are associated with systemic lupus erythematosus (SLE) risk, for the first time, in Egyptian pediatrics and adolescents. Materials & methods: sCD14 concentrations were determined in plasma of 95 SLE cases and 98 healthy controls using ELISA assay. Genotyping was performed using TaqMan technology. Results: sCD14 levels were elevated in SLE. Individuals with T, CT and TT genotypes in rs2569191 were of significant risk (odds ratio = 1.471-2.035, 95% CI = 1.138-3.471) and those with combined CT+TT and haplotype GT were of higher risk of SLE (odds ratio = 1.660-1.758, 95% CI = 1.003-3.106, p < 0.05). sCD14 levels and CD14 polymorphism were not correlated with SLE clinical and laboratory features. Conclusion: In SLE, sCD14 levels are associated with rs2569190 A/G. Genotype CT+TT in rs2569191 C/T and haplotype GT are associated with SLE risk in Egyptian pediatric and adolescents.

Plasma interleukin-22 level, variants in interleukin-22 gene polymorphism, and the severity of systemic lupus erythematosus among Egyptian pediatric and adolescents.

OBJECTIVES: Our purpose was to investigate, for the first time, genotypes and alleles distribution of two single nucleotide polymorphisms (SNPs) of interleukin 22 (IL-22) (rs1012356 and rs2227485) in Egyptian pediatric and adolescents with systemic lupus erythematosus (SLE) and to evaluate the plasma IL-22 levels and their association with gene polymorphism and SLE risk and severity. METHODS: The TaqMan™ SNP genotyping assay on a real-time polymerase chain reaction (PCR) system was employed to evaluate the polymorphism's genotypes. Plasma IL-22 levels were determined by using an enzyme-linked immunoabsorbent assay (ELISA). RESULTS: The frequencies and genotypes of rs2227485 and rs1012356 in IL-22 between SLE patients and controls also haplotypes formed by the same SNPs revealed no statistically significant difference (p > 0.05). Otherwise, logistic regression analysis revealed that patients carrying rs1012356 "TA + AA" genotype had increased risk for prediction of SLE activity (OR = 1.610, 95% CI = 1.339-2.760, p = 0.034) by lowering plasma IL-22 level. CONCLUSIONS: Among Egyptian pediatric and adolescents, we confirm a combined model "TA + AA" in rs1012356 (A/T) of IL-22 in regression analysis, as an independent predictor for SLE activity by lowering IL-22 plasma levels. Despite neither SNP rs2227485 A/G in IL-22 gene nor haplotypes formed by the same two SNPs (rs2227485 A/G and rs1012356 A/T) were significantly associated with the clinical and/or laboratory manifestations of SLE.

A simple diagnostic index comprising epithelial membrane antigen and fibronectin for hepatocellular carcinoma.

UNLABELLED: Background and rationale for the study. Continuing search for suitable tumor-markers is of clinical value in managing patients with various malignancies. These markers may be presented as intracellular substances in tissues or may be released into the circulation and appear in serum. Therefore, this work is concerned with identification and quantitative determination of epithelial membrane antigen (EMA) and fibronectin and estimating their performances as surrogate markers for identifying hepatocellular carcinoma (HCC). RESULTS: A total of 627 individuals constituted this study [fibrosis (F1-F3) = 217; cirrhosis = 191; HCC = 219]. Western-blot was used for identifying EMA and fibronectin in sera. As a result, a single immunoreactive band was shown at 130-kDa and 90-kDa corresponding to EMA and fibronectin, respectively. They were quantified using ELISA providing values in HCC higher than fibrosis or cirrhosis with a significant difference (P < 0.0001). For identifying HCC, EMA showed 0.82 area under receiver-operating characteristic curve (AUC) with sensitivity = 70% and specificity = 78% while fibronectin yielded AUC = 0.70 with sensitivity = 67% and specificity = 82%. FEBA-Test comprising fibronectin and EMA together with total-bilirubin and AFP was constructed yielding AUC = 0.92 for identifying HCC from cirrhosis with sensitivity = 89% and specificity = 85%. FEBA-Test was then tested for differentiating HCC from fibrosis showing AUC = 0.97 with sensitivity = 90% and specificity = 89%. FEBA-Test enabled the correct identification of HCC patients with CLIP 0-1 and size ≤ 3 cm with AUC = 0.80 and AUC = 0.84, respectively, indicating its ability in identifying early HCC. CONCLUSIONS: A four-marker index may improve the early detection of HCC with a high degree of accuracy.

Evaluation of serum levels of p53 in hepatocellular carcinoma in Egypt.

Hepatocellular carcinoma (HCC) is one of the most common causes of cancer-induced death. Somatic mutation of the p53 gene is the most common genetic abnormality so far described in human cancer and there is evidence that supports a high level of p53 alterations in HCC. The aim of this study was to investigate serum levels of p53 in Egyptian patients with HCC, and its relation to other prognostic factors such as tumor grade, alpha-fetoprotein (AFP), and liver function tests in an attempt to clarify their significance in the pathogenesis of the disease. Liver function tests were carried out and AFP and p53 levels were measured for all individuals studied. Our results show that detection of p53 increased the frequency of HCC prediction from 79.5% to 86.3%. Moreover, significant positive correlation between p53 and tumor size (cm) for tumor grade II and III was identified. In conclusion, serum concentration of p53 protein may be a convenient and useful non-invasive screening test for prediction of HCC.
