    Abstract Background: We compared the characteristics of clinical Staphylococcus aureus and S. aureus isolated from environmental surfaces in 3 hospitals.
    Methods: Clinical S. aureus isolates were collected from hospitalized patients. Environmental surfaces were sampled from the rooms of patients infected with S. aureus. After identifying rooms with the target organism, 3-5 high-touch surfaces in patient care areas were sampled using swabs before room cleaning by environmental services. S. aureus isolates were subjected to genotyping, antimicrobial susceptibility testing, and virulence determinant screening. The isolates were analyzed for integron content and sequences of variable region amplification products.
    Results: There were epidemiologically unrelated 79 clinical and 62 environmental S. aureus isolates. Overall, 11.4% of clinical and 59.7% of environmental isolates were methicillin-resistant. The environmental and clinical S. aureus exhibited very different virulence profiles: 79% of the environmental isolates were negative for virulence genes compared to 2.5% of clinical isolates (P < .001). Environmental isolates were more resistant to antibiotics compared to clinical isolates. Class 1 integrons were only detected in 7 of 62 environmental isolates, of which 3 isolates had integrons with cysteine synthase cassette, 1 had aadA1, and 1 had an unknown cassette.
    Conclusion: These data indicate the different characteristics between environmental and clinical S. aureus, which may reflect different reservoirs from which the 2 groups acquired the strains.

    Abstract One of the symptoms of glomerular damage is proteinuria and nephrotic syndrome, which can be primary or secondary. Secondary nephrotic syndrome is followed by systemic diseases, malignancies, drugs, and a variety of infectious diseases. In the recent Coronavirus disease 2019 pandemic, a wide range of organ involvement has been reported, including, kidneys, cardiovascular, endocrine, and nervous systems, mostly in adults and less reported in children. Our patient was an 11-year-old child with COVID-19 who presented with diabetic ketoacidosis and developed proteinuria, nephrotic syndrome, and renal failure during the course of the disease and mild respiratory symptoms appeared at the end of the illness.

    Abstract Introduction: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), or COVID-19, is a pandemic infectious disease involved all over the world. Its mortality, especially in cases with additional co-morbidities, is so high that is has attracted the attention of the world. Diabetes mellitus is known as one of its risk factors for mortality. Case Presentation: A unique case of pediatrics COVID-19 who presented with diabetic ketoacidosis (DKA) is reported in this manuscript as the first presentation. He presented with abdominal pain, nausea, and vomiting. RT-PCR test for COVID-19 via nasal swab was performed, and a positive diagnosis was obtained. Chest CT scan confirmed the diagnosis with multifocal bilateral patchy consolidation. Case was discharged after usual treatment of COVID-19. Conclusion: In pediatrics, this disease can be subtle and have a confusion presentation, but it should be controlled to avoid spread of the disease. During epidemic status, suspicious cases specially children with nonspecific symptoms and other underlying diseases should be considered as at risk or potentially asymptomatic COVID-19 cases.

    Abstract Introduction: The human immunodeficiency virus (HIV) is still a remarkable challenge throughout the world, especially in developing countries. Despite the fact that HIV in children is becoming one of the most challenging diseases, it seems that pediatric AIDS in Iran is an unknown disease and there is a lack of studies about it. The aim of this study was to describe the characteristics of HIV-positive children who referred to the hospitals of Tehran, Kermanshah, Kurdistan, and Qom provinces of Iran.
    Materials and methods: This study was a retrospective investigation of medical records among 61 children with a diagnosis of HIV who were admitted to the children's hospitals in the four provinces of Iran during a 3-year period (2013-2016).
    Results: The frequency of HIV in the center of Iran (Tehran and Qom provinces) was higher (N = 37, 61%). Most of the infected patients were between 5 and 15 years old, 52% were male, and 93% had a history of HIV in their family. Median age at diagnosis of HIV was 2 years. Most of the hospitalized patients were discharged and only two patients (3%) died due to HIV infection. The vast majority of patients (93%) were infected through maternal transmission and a low percentage (29%) were diagnosed before 1 year of age. All of them were in the third stage of the disease. All patients had a positive HIV PCR test. HIV EIA was positive in the majority of cases (98%). A history of addiction in the family was demonstrated in 22 cases (36%). Weight loss (N = 51, 84%), prolonged fever (N = 50, 81%), and respiratory infection (N = 26, 47%) were the most common symptoms.
    Conclusion: This study demonstrated a high frequency of pediatric HIV among children aged 5-15 years in four provinces of Iran. Novel strategies to prevent and eliminate mother-to-child transmission of HIV, diagnostic facilities, and treatment of infected mothers during pregnancy in our country are highly recommended.

    Abstract A simple and efficient procedure for the preparation of 14-aryl-14H-dibenzo[a,j]xanthenes, 1,8-dioxooctahydroxanthenes and tetrahydrobenzo[a]xanthene-11-ones is described using N-sulfonic acid poly(4-vinylpyridinium) chloride (NSPVPC) as a heterogeneous and efficient catalyst under solvent-free conditions. The structures of the products were characterized by their physical constants, comparison with authentic samples and IR, ¹H NMR and ¹³C NMR spectroscopy. Simple methodologies, easy work-up procedure, easy preparation of the catalyst, excellent yields and short reaction times are some advantages of this work. Further, the catalyst can be reused and recovered for several times without significant decrease in its activity.

    Abstract P4VPy–CuO nanoparticles as a novel solid catalyst were synthesized using an ultrasound irradiation method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Fourier Transform Infrared (FT-IR) spectroscopy. The prepared catalyst was applied to the green, simple and highly efficient synthesis of bis(indolyl)methanes and 3,3′-(arylmethylene)bis(4-hydroxycoumarins). This methodology has some advantages such as short reaction times, environmentally friendly conditions, easy work-up, and excellent yields. This catalyst can be easily separated and re-used without any appreciable loss in its activity.
