The issue beyond resistance: Methicillin-resistant Staphylococcus epidermidis biofilm formation is induced by subinhibitory concentrations of cloxacillin, cefazolin, and clindamycin.

Staphylococcus epidermis is one of the most frequent causes of device-associated infections due to biofilm formation. Current reports noted that subinhibitory concentrations of antibiotics induce biofilm production in some bacteria. Accordingly, we evaluated the effect of exposure of different subinhibitory concentrations of cloxacillin, cefazolin, clindamycin, and vancomycin on the biofilm formation of methicillin-resistant S.

Patterns of Antiepileptic Drug Reactions in Children: A Multicenter Study.

Objectives: Antiepileptic drugs are among the most common triggers of cutaneous adverse reactions. About 5-17% of epileptic patients develop idiosyncratic skin reactions at some point during their treatment course, most of which occur within the first two months of drug initiation. This study aimed to investigate the pattern of cutaneous drug reactions associated with anticonvulsant use among the pediatric population in Iran to identify high-risk individuals.

Highly Synergistic Effects of Melittin With Vancomycin and Rifampin Against Vancomycin and Rifampin Resistant .

Methicillin-resistant (MRSE) strains are increasingly emerging as serious pathogens because they can be resistant to many antibiotics called multidrug resistance (MDR) that limit the therapeutic options. In the case of vancomycin- and rifampin-resistant MDR-MRSE, the physicians are not allowed to increase the doses of antibiotics because of severe toxicity. Accordingly, we investigated the synergistic activity of melittin antimicrobial peptide with vancomycin and rifampin against vancomycin-resistant, and rifampin-resistant MDR-MRSE isolates.

BCG-Induced cold abscess as a complication of inadvertent vaccine injection: A case series.

We report a four-month-old girl with a right thigh swelling, an eight-month-old girl with a left thigh swelling, and a five-month-old boy with a left thigh swelling with the final diagnosis of BCG-induced cold abscess as a result of erroneous injection of BCG vaccine into the infants' thigh muscle.

Prevention, inhibition, and degradation effects of melittin alone and in combination with vancomycin and rifampin against strong biofilm producer strains of methicillin-resistant Staphylococcus epidermidis.

Methicillin-resistant Staphylococcus epidermidis (MRSE) bacteria are being recognized as true pathogens as they are able to resist methicillin and commonly form biofilms. Recent studies have shown that antimicrobial peptides (AMPs) are promising agents against biofilm-associated bacterial infections. In this study, we aimed to explore the antibiofilm activity of melittin, either alone or in combination with vancomycin and rifampin, against biofilm-producing MRSE strains.

Protective Effects of Omega-3 Fatty Acids Supplementation Against Renal Parenchymal Scarring in Children with Acute Pyelonephritis: Results of a Pilot Clinical Trial.

Aim: This trial aimed to determine if supplementation with omega-3 fatty acids as an adjunct therapy to antibiotic treatment can have protective effects against renal scar formation after acute pyelonephritis (APN) in pediatric patients.

Background: Current evidence points out that besides antibiotic treatment, early administration of antioxidant and anti-inflammatory compounds may be effective in reducing the occurrence of renal damage following APN in children.

Objective: The main endpoint of the trial was the comparison of the development of renal scarring formation after APN in an omega-3 fatty acids-treated group and in a control-treated group.

Novel G6PC3 Mutations in Patients with Congenital Neutropenia: Case Reports and Review of the Literature.

Background: Severe congenital neutropenia (SCN4) caused by mutations in glucose-6- phosphatase catalytic subunit 3 (G6PC3) is characterized by recurrent infections due to severe neutropenia, may be accompanied by other extra-hematopoietic manifestations; including structural heart defects, urogenital abnormalities, prominent superficial venous markings, growth retention, and inflammatory bowel diseases with rare incidence. The homozygous or compound heterozygous mutations of G6PC3 are responsible for most cases of autosomal recessive SCN4. Herein, we present two cases of SCN4 affected by novel mutations in the G6PC3, in addition to a summarized list of variants in G6PC3 gene that are reported as pathogenic and related to the SCN4 phenotype.

Epidemiological Profile of Meningitis following Pentavalent Vaccination in Iran: Impact of Vaccine Introduction.

Ensuring the effectiveness of the (DTwP-Hib-HepB) vaccine in reducing meningitis is an essential approach in evaluating the effectiveness of the vaccine. The study aimed to address the epidemiology of meningitis following pentavalent vaccination in Iran.

Novel mutation in X-linked agammaglobulinemia: Report of a 17-year-old male.

Introduction And Objectives: X-linked agammaglobulinemia (XLA), the first known primary immunodeficiency, is caused by rare mutations in Bruton's tyrosine kinase (BTK) gene. Mutations in the BTK gene lead to a failure in the development and maturation of B-cell linage. A decreased number of B-cells results in agammaglobulinemia and increased susceptibility to a variety of infections.
