ABSTRACT

Neonatal acute suppurative parotitis is rare. Staphylococcus aureus is the most common pathogen and antibiotic treatment is the first line therapy. Here, we report a case of acute suppurative parotitis caused by Escherichia coli in a 7­day­old male with febrile sensation, parotid swelling, and purulent discharge from the Stensen duct who was treated successfully with intravenous antibiotics. To the best of our knowledge, this is the first case of neonatal suppurative parotitis caused by E. coli in Korea.

ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) is rare in pediatric patients compared to adults, but it's incidence is gradually increasing. The purpose of this study was to analyze the incidence, risk factors, and prognosis of pediatric patients with VTE in Korea. METHODS: Between January 2000 and July 2017, 249,312 medical records of the patients older than 1 year who were hospitalized in the department of pediatrics of 10 university hospitals in Yeungnam region were retrospectively reviewed. RESULTS: The overall incidence of VTE was 4.9 per 10,000 admissions. Of the total 123 patients, 80 (65.0%) were male and the median age was 10.8 years (range, 1.0–23.5 years). Magnetic resonance imaging was performed most frequently to confirm the diagnosis of VTE (43.1%). Thrombosis occurred in the cerebral vessels (46.3%), lower extremities (23.8%), pulmonary (19.5%), abdomen (9.8%), and upper extremities (4.1%). One hundred and six patients had underlying causes such as cancer (27.6%), infection (26.8%), intravenous catheter insertion (17.9%), and surgery (14.6%). Protein C was evaluated in 39 patients (31.7%), protein S in 40 (32.5%), antithrombin (AT) III in 52 (42.3%), and homocysteine in 21 (17.1%). Among them, one patient with a family history of AT III deficiency had SERPINC gene mutation. Seventy-seven patients (62.6%) started anticoagulation treatment. Most (52.0%) were treated for more than 90 days. CONCLUSION: Healthcare providers must be aware of the potential for VTE development in childhood. In the near future, a nationwide survey should be investigated to determine the incidence rate and the trends in VTE among Korean children.

ABSTRACT

BACKGROUND/AIMS: The standard guideline for the management Helicobacter pylori infection in Korean children is not present until now. In present study, we conducted the questionnaire survey to investigate the real situation of H. pylori eradication in children. MATERIALS AND METHODS: Questionnaire concerning the indications of H. pylori eradication, the first choice of treatment modality, the decision method of eradication result, experience of eradication failure, the second choice of treatment modality was sent to doctors who are members of the Korean Society for Pediatric Gastorenterology, Hepatology, and Nutrition. RESULTS: A total of 28 doctors (90.3%) answered the questionnaires among 31 doctors. The most common indication for eradication of H. pylori was peptic ulcer (n=24) followed by chronic abdominal pain (n=17) and positive family history of gastric cancer (n=12). The most common choice of first-line eradication therapy was omeprazole, amoxicillin, clarithromycin triple therapy (n=21) and followed by bismuth subsalicylate, amoxicillin, metronidazole, clarithromycin quadruple therapy (n=7). The results of treatment were judged by C13-urea breath test after 2 months later in 19 doctors (67.8%). Twenty four (85.7%) out of 28 doctors had experienced treatment failure. The most common second-line therapy was the sequential therapy (58.3%, 14 doctors among 24). CONCLUSIONS: This was the first study for the survey of the treatment of H. pylori infection to Korean pediatricians. The results of this study showed that most pediatric gastroenterologists used to treat H. pylori infection according to the textbook and the common use of bismuth-based quadruple therapy for the first-line treatment was notable.

ABSTRACT

To identify the Helicobacter pylori antigens operating during early infection in sera from infected infants using proteomics and immunoblot analysis. Two-dimensional (2D) large and small gel electrophoresis was performed using H. pylori strain 51. We performed 2D immunoglobulin G (IgG), immunoglobulin A (IgA), and immunoglobulin M (IgM) antibody immunoblotting using small gels on sera collected at the Gyeongsang National University Hospital from 4–11-month-old infants confirmed with H. pylori infection by pre-embedding immunoelectron microscopy. Immunoblot spots appearing to represent early infection markers in infant sera were compared to those of the large 2D gel for H. pylori strain 51. Corresponding spots were analyzed by matrix-assisted laser desorption/ionization time of flight-mass spectrometry (MALDI-TOF-MS). The peptide fingerprints obtained were searched in the National Center for Biotechnology Information (NCBI) database. Eight infant patients were confirmed with H. pylori infection based on urease tests, histopathologic examinations, and pre-embedding immunoelectron microscopy. One infant showed a 2D IgM immunoblot pattern that seemed to represent early infection. Immunoblot spots were compared with those from whole-cell extracts of H. pylori strain 51 and 18 spots were excised, digested in gel, and analyzed by MALDI-TOF-MS. Of the 10 peptide fingerprints obtained, the H. pylori proteins flagellin A (FlaA), urease β subunit (UreB), pyruvate ferredoxin oxidoreductase (POR), and translation elongation factor Ts (EF-Ts) were identified and appeared to be active during the early infection periods. These results might aid identification of serological markers for the serodiagnosis of early H. pylori infection in infants.
