RESUMO

BACKGROUND: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system, rare during childhood. MS variations, like tumefactive MS and Balo concentric sclerosis, constitute puzzling to treat diagnostic dilemmas for pediatric patients. Differential diagnosis, mainly from brain tumors, is an absolute necessity. In addition, apart from treating acute attacks, immunomodulatory alternatives are limited. CASE: We present a 12.5-year-old boy diagnosed, 5 years ago, with tumefactive relapsing-remitting MS, with severe recurrent clinical attacks. Definite diagnosis of demyelination was achieved via combined brain imaging including magnetic resonance (MR) imaging, MR spectroscopy and computed tomography, avoiding brain biopsy. Acute attacks showed satisfactory response to aggressive treatment choices, like plasmapheresis and cyclophosphamide, but age-appropriate immunomodulating treatment was available, only 2 years later. Finally, after a last radiological relapse, when he was 10 years old, fingolimod was initiated. He has been clinically and radiologically stable since, presenting an excellent treatment tolerance.

RESUMO

BACKGROUND: As Greece is a country which has introduced the 13-valent pneumococcal conjugate vaccine (PCV13) both in the infant and in the adult immunization programs, the aim of the study was to investigate age-specific and serotype-specific trends of pneumococcal meningitis over an 11-year period (2010-2020). MATERIALS AND METHODS: Data are reported from pneumococcal meningitis cases [notified to the National Public Health Organization (NPHO)], with clinical samples and bacterial isolates sent for pneumococcal identification and serotyping at the National Meningitis Reference Laboratory (NMRL). Pneumococcal identification was performed directly on clinical samples or bacterial isolates by multiplex PCR (mPCR) assay, while serotyping was carried out by application of the Capsular Sequence Typing (CST) method with the combination of single tube PCR assays. RESULTS: A total of 427 pneumococcal meningitis cases were notified to the NPHO between 2010 and 2020. Among those, 405 (94.8%) were microbiologically confirmed, while samples from 273 patients were sent to the NMRL for identification and/or further typing. The annual notification rate peaked at 0.47/100,000 in 2016 and since then has been decreasing. The incidence was highest in infants and in older adults. Pneumococcal serotypes were identified in 260/273 (95.2%) cases, where clinical samples were sent to the NMRL. The most prevalent serotypes (≥5%) were 3, 19A, 23B, 15B/C, 11A/D, 23A, 22F. During the study period there has been a decrease of PCV13 serotypes combined with an increase of non-PCV13 serotypes (p = 0.0045). CONCLUSIONS: This is the first study to report serotypes for pneumococcal meningitis across all ages in the post-PCV13 era in Greece. There is a need to enhance surveillance, by close monitoring of the emerging serotypes and the impact of vaccination programs. Higher-valency PCVs may help to improve the coverage of pneumococcal disease.

RESUMO

As the COVID-19 pandemic evolves, the medical community continues to report a variety of clinical manifestations of SARS-CoV-2 in the pediatric population. Although younger age groups experience less severe disease, attention is given to the immunologic manifestations of the disease. Pericarditis is a rare cardiac complication of COVID-19 infection. We discuss the first case of delayed presentation of pericarditis following recovery from COVID-19 infection in the pediatric population. A 15-year-old male adolescent presented to the emergency department (ED) with a two-day history of left-sided, sub-sternal chest pain that worsened during inspiration and a low-grade fever. Twenty days prior to this presentation, the patient experienced fever and was tested positive for SARS-CoV-2. His family history was remarkable for Hashimoto thyroiditis and rheumatoid arthritis, with his mother having experienced 18 episodes of pericarditis during the exacerbations of her disease. RT-PCR for SARS-CoV-2 was negative on this occasion and the serology assay identified positive IgG antibodies against the virus. The ECG was suggestive for pericarditis and the diagnosis was confirmed by the presence of pericardial effusion on ECHO. The rest of the aetiological investigations for pericarditis were negative. In view of the strong family history of autoimmunity, questions were raised in the medical team of our hospital regarding the etiology of his pericarditis and on whether it represented a postinflammatory immune-mediated presentation of SARS-CoV-2 or a new-onset autoimmune disease.

RESUMO

AIM: We reported a case of Miller Fisher syndrome following a breakthrough varicella zoster virus infection in an otherwise healthy 6-year-old male. The objective of this review was to summarize the infectious etiologic agents known to trigger Miller Fisher syndrome. METHODS: Review of the literature on infections associated with Miller Fisher syndrome. RESULTS: We identified 762 studies after duplicates were removed. Titles, abstracts, and full texts were screened. Finally, 37 studies were included in qualitative synthesis after citations and reference list were checked. The age range of cases reported was 0-78 years, and male sex was predominant in studies where these parameters were reported. The most common causative agent was Campylobacter jejuni followed by Haemophilus influenzae. CONCLUSIONS: Our review highlights the importance of recognizing the infections triggering Miller Fisher syndrome. We also present a unique case of Miller Fisher syndrome associated with breakthrough varicella zoster virus infection. Preventive policies may consider population immunization for certain causative agents.

RESUMO

AIM: A spinal epidural abscess (SEA) is a rare paediatric bacterial infection, with possible devastating neurological sequelae. We explored localisation in the cervical segment, which is unusual, but more dangerous, than other SEAs. METHODS: We describe 22 cases (12 male) of paediatric SEAs without risk factors: 21 from a literature search from 2000 to 2017 and a 30-month-old boy with a spontaneous cervical SEA due to Group A Streptococcus. RESULTS: The average age was eight years and the symptoms were mainly fever, back pain and motor deficit, with an aetiological diagnosis in 68%. Methicillin-sensitive Staphylococcus aureus was isolated in six patients, methicillin-resistant Staphylococcus aureus in two, Staphylococcus aureus with unknown susceptibility patterns in three and Group A Streptococcus in four. All patients underwent gadolinium-enhanced magnetic resonance imaging and most abscesses were localised in the thoracic and lumbar areas. More than half (59%) underwent surgery to remove pus and granulation tissue and nine were just treated with antimicrobial therapy for an average of 5.3 weeks. Most patients had good outcomes. CONCLUSION: SEAs were underestimated in children due to the rarity and spectrum of differential diagnoses. Timely diagnosis, immediate antibiotics, spinal magnetic resonance imaging and prompt neurosurgical consultations were essential for favourable outcomes.

RESUMO

BACKGROUND: Urinary tract infection (UTI) is the most common serious bacterial infection in childhood. The aim of the present study was therefore to identify the organisms responsible for community-acquired febrile UTI in children, to investigate their susceptibility to commonly used antibiotics, and to identify possible risk factors for antibiotic resistance. METHODS: A total of 284 children (male, 38%; female, 62%), who were hospitalized due to a community-acquired UTI over a 5 year period in a general district hospital of southern Greece, were enrolled in the study. RESULTS: Escherichia coli was the leading uropathogen followed by Klebsiella spp. (9.15%) and Proteus spp. (5.28%). E. coli isolates were most commonly resistant to ampicillin (41.8%), followed by piperacillin (40.3%), amoxicillin-clavulanic acid (28.6%) and trimethoprim-sulfamethoxazole (17.8%), while 27 strains (12.6%) were multi-drug resistant (MDR). Of the E. coli strains, 4.21% were producing extended-spectrum beta-lactamases. Parenteral second- and third-generation cephalosporins, the most commonly used antibiotic agents (81.3%) in the present cohort, remained highly active against E. coli and other urinary isolates, given that >95% of E. coli strains were susceptible to cefuroxime and cefotaxime. Vesicoureteral reflux was a significant risk factor for MDR (P = 0.04). CONCLUSION: Contrary to current local practice, amoxicillin/clavulanic acid may not be the best option for the empirical treatment of community-acquired UTI in southern Greece.
