Emerging importance of multidrug-resistant Stenotrophomonas maltophilia infections in neonatal intensive care unit in a tertiary center in Turkey.

OBJECTIVE: Stenotrophomonas maltophilia is an emerging multi-drug resistant, opportunistic pathogen in the neonatal intensive care unit (NICU). In this study, we aimed to assess the incidence, clinical features, antibiotic susceptibility, and treatment options of S. maltophilia infection among the healthcare-associated infections (HAIs) in the neonatal unit. METHODS: In this study, the patients who were hospitalized in the NICU between January 2020 and December 2021 with S. maltophilia isolated from clinical samples were included. Demographic, clinic features, and microbiological findings of the patients were retrospectively evaluated by using the medical records. The samples (lower respiratory tract, urine, peritoneal fluid) were first examined microscopically by gram preparation and cultured. Antibiotic susceptibility tests were performed according to the recommendations of The European Committee on Antimicrobial Susceptibility Testing (EUCAST) for TMP-SMX. RESULTS: S. maltophilia was isolated in 38 clinical samples of the 20 patients who were hospitalized at the NICU between January 2020 and December 2021. A total of 40 % (n = 8) of samples from different patients were accepted as colonization. Ventilator-associated pneumonia was determined in 55 % (n = 11), and urinary tract infection in 5 % (n = 1). S. maltophilia-associated bacteremia was not detected in any of the cases. The TMP-SMX susceptibilities of the strains were as it follows: 3 (15 %) were resistant (R), 7 (28 %) were susceptible (S), and 10 (47 %) were susceptible-increased exposure (I). Three of these patients were given dual antibiotics therapy (levofloxacin plus TMP-SMX) and nine of them were given only TMP-SMX. The most common hospital-acquired infectious agents are Gram negative microorganisms (51 %), followed by coagulase negative staphylococci (CNS), Staphylococcus aureus (24 %) and S. maltophilia (24 %). CONCLUSION: Increasing TMP-SMX resistance and specific drug and dosage-related problems in the neonatal unit are important problems in treatment management.

[Long COVID in Children: A Pediatric Center Experience]. / COVID-19 Nedeniyle Hastanede Yatan Çocuk Hastalarda Uzun Dönem Etkilerin ve Uzamis COVID Sikliginin Degerlendirilmesi.

Although COVID-19 (Coronavirus disease-2019) is observed to be milder in children, it has been observed that the symptoms continue for a long time in many people after the acute period of the disease, especially the multisystemic inflammatory syndrome (MISC) that developed after COVID-19 with the progression of the pandemic. Although it was first defined by different names such as long COVID and post COVID in adults, it has been observed in studies that similar complaints such as cough, fatigue and difficulty in concentrating continue for a long time in children, just as in adults. In our study, we aimed to evaluate the status of long COVID in childhood. Our study included patients aged from one month to 18 years with moderate and severe symptoms who were hospitalized and discharged for SARS-CoV-2 infection in Istanbul University Faculty of Medicine between November 1, 2020 and November 1, 2021. A questionnaire form was created to learn about the complaints of the patients and their ongoing complaints. The patients/parents were called by phone and their complaints were recorded in the questionnaire. The patients were classified according to the definitions in the guidelines published by NICE, RCGP and SIGN. In total, 116 patients were included; 57.8% (n= 64) male, 42.5% (n= 49) female; 53.4% (n= 62) 0-9, 46.6% (n= 54) 10-18 years old. Comorbid conditions were found in 64 (55.2%) patients. The mean follow-up period was 5.90 ± 3.61 [min-max (1-12)] months; longest symptom durations: decrease in effort loss/fatigue 19.25 ± 74.56 (0-365) days, concentration difficulties 11.12 ± 49.75 (0-365) days, fatigue 9.61 ± 34.96 (0-365) days and cough were 8.34 ± 35.37 (0-365) days. The percentage of the patients who met the definition of subacute/ongoing symptomatic COVID-19 was 37.9% (n= 44). The most common symptoms were the decrease of effort capacity/fatigue 12.1% (n= 14) and the concentration difficulties 10.3% (n= 12) in subacute symptomatic patients. The percentage of patients matching the definition of chronic/post COVID-19 was 11.2% (n= 13). In the first year of the disease, ongoing complaints such as fatigue and concentration difficulties were observed in eight patients. The rate of concentration difficulties in the 10-18 age group was statistically significantly higher than the 0-9 age group (p= 0.037). In terms of other symptoms, no significant difference was found according to age, gender and concomitant disease status. Out of these, one patient was diagnosed with Type 2 diabetes mellitus during the acute illness, and two patients were diagnosed with allergic rhinitis after COVID-19. A statistically significant difference was found in the rates of concentration disorders according to age groups with subacute/ongoing symptoms. Although only the hospitalized patients were included, fatigue and difficulty in concentration were among the most common ongoing symptoms in our study, similar to the literature, and they were seen to be more common in older children. It is important both for early diagnosis and awareness to follow up children with COVID-19 in terms of symptoms, not only in terms of prolonged symptoms but also in terms of new diseases.

Comparison of the neurocognitive outcomes in term infants treated with levetiracetam and phenobarbital monotherapy for neonatal clinical seizures.

PURPOSE: This study aims to compare the neurocognitive outcome in term infants who were treated using phenobarbital (PB) and levetiracetam (LEV) monotherapy for neonatal clinical seizures. METHODS: Term infants who were treated using PB or LEV monotherapy as the first-line anti-epileptic treatment for neonatal clinical seizures and followed-up in a pediatric neurology outpatient clinic were enrolled in this study. Neurodevelopmental outcome assessments were carried out using the Bayley Scales of Infant Development, third edition (BSID-III), including cognitive, receptive language, expressive language, fine motor and gross motor subscales. RESULTS: The study group consisted of 62 infants who received monotherapy with PB monotherapy (n = 22) and LEV (n = 40). The mean duration of monotherapy treatment was 8 ± 6 months. There was no statistically significant difference between PB and LEV monotherapy groups concerning each outcome parameter on the BSID-III. There was also no statistically significant difference between PB and LEV monotherapy subgroups excluding the infants with neurodevelopmental impairment with a BSID-III scale score<7 or a composite score<85. CONCLUSION: Our findings suggest that both LEV and PB therapy can be equally safe as monotherapy for neonatal clinical seizures for the neurodevelopmental outcome assessment with BSID-III.
