  • Kikuchi disease(subacute necrotizing lymphadenitis), first reported by Kikuchi and Fujimoto in 1972, is a benign self-limiting illness characterized by fever, neutropenia and cervical lymphadenopathy and develops predominantly in young women, especially in Asia. The cause of Kikuchi disease is unknown, but postinfectious(virus or bacteria) hyperimmune reaction has been suggested. Few pediatric cases have been reported. We experienced a case of Kikuchi disease associated with Yersinia pseudotuberculosis infection in 12-year-old girl. After she was admitted with cervical lymphadenopathy and headache, followed by sustained fever with leukopenia. All symptoms and signs did not seem to be responded to antimicobial treatment. Open biopsy of cervical lymph node was performed and showed findings consistent with subacute necrotizing lymphadenitis. Serologic studies were all negative except for Y. pseudotuberculosis. Fever subsided and lymphadenopathy improved after administration of oral steroid for 1 week.

  • On the treatment of Kawasaki disease, approximately 10% of children treated with IVIG have persistent or recrudescent fever despite IVIG treatment. We had experienced two children with Kawasaki disease who did not respond after multiple dosages of IVIG. They were treated within the first 10 days of onset of fever and were given oral aspirin (100mg/kg/day) and IVIG(2gm/kg) in a single infusion for 8 to 10 hours. The first child had not resolution of symptoms after three intravenous doses of IVIG(total 4gm/kg). And then treated with high dose methylprednisolone(30mg/kg) for 2 to 3 hours intravenously without symptoms improvement. On fifth hospital days, he was retreated with IVIG (2gm/kg) again with ultimate resolution of symptoms. The second child had resolution of symptoms after three intravenous doses of IVIG(total 4gm/kg). No adverse events were associated with the administration of IVIG or steroid. We reported two cases of IVIG non-responded Kawasaki disease with a brief review of the related literatures.

  • The anti-inflammatory activity of water extract of Mahaengeuigam-Tang(MHEGTWE) was examined using the carrageenin and acetic acid induced edema, croton oil induced granuloma pouch, and adjuvant arthritis in rats. In addition, the acute toxicity, analgesic and antipyretic effects of MHEGTWE were investigated by the general experimental methods. In acute toxicity test in mice, MHEGTWE showed 10% mortality at 2400 mg/kg(p.o), but it did not showed at 1200 mg/kg(i.p). It was also showed significant analgesic action on the writhing syndrome induced by 0.7% acetic acid at 600 mg/kg(p.o) and its antipyretic activity was observed in the typhoid vaccine induced fevered rats at 300 mg/kg(p.o). By the oral administration of the MHEGTWE, the significant anti-inflammatory activity was observed on 1% carrageenin induced edema, and it significantly inhibited the granuloma and exudate formation in rats. In the adjuvant arthritis experiment, the MHEGTWE decreased the hind paw edema in rats for 19 days. The results suggest that MHEGTWE has analgesic, anti-inflammatory and antipyretic action.

  • Vertebral osteomyelitis represents only 1% to 2% of osteomyelitis and may pose a diagnostic conundrum, with disastrous consequences if diagnosis and therapy are delayed. We report a neonate with the unique association of vertebral osteomyelitis and MRSA infection. A 1-month-old boy was admitted to the hospital for evaluation of high fever and decreased oral intake. He was born at 34 wks, and his birth weight was 1.6 kg. We founded MRSA on his blood culture. Magnetic resonance imaging study showed findings of T7-T8 vertebral osteomyelitis. With 8 weeks of intravenous vancomycin treatment, the patient improved clinically and radiologically.

  • This study was carried out to obtain basic information for possibility of oral vaccine in carrot using Agrobacteruim -mediated transformation system. The epitope region of porcine epidemic diarrhea virus (PEDV) spike gene which is classified as a member of the Coronaviridae and causes an acute enteritis in pigs was successfully expressed in carrot (Daucus carota) using the Agrobacterium-mediated transformation system. Hypocotyl segments of in vitro germinated plantlets were infected with Agrobacteriun tumefaciens LBA 4404 harboring PEDV spike gene. Embryogenic callus (EC) was induced on MS selection medium with 1 mg/L 2,4-D, 50 mg/L kanamycin and 300 mg/L cefotaxime after 45 days of culture. Subcultured ECs on MS selection medium without 2,4-D were converted to somatic embryos (SE) of various stage; globular, heart and torpedo stage. Putative transgenic embryos were selected on MS medium with 50 mg/L kanamycin and 300 mg/L cefotaxime. Regenerated plantlets from transformed SE were induced on MS medium containing 50 mg/L kanamycin after 30 days of culture. Genomic PCR confirmed the integration of PEDV spike gene into nuclear genome of carrot and northern blot analysis demonstrated the expression of PEDV spike gene in transgenic carrot.

  • To construct a novel vaccine candidate against bovine enterotoxigenic Escherichia coli (ETEC), FanC, the major subunit of K99 fimbriae adhesion, was inserted into secretion plasmid pYA3560 containing a ${\beta}-lactamase$ secretion system. This was then transformed into ${\Delta}asd$ ${\Delta}crp$ Salmonella (S.) Typhimurium and designated as JOL950. Secretion of recombinant fanC fimbrial antigens was confirmed by immunoblot analysis. Groups of mice were inoculated with single or double doses of JOL950. Another group was used as a negative control. Compared to control mice, all immunized mice had significantly higher levels (p < 0.05) of serum immunoglobulin (Ig)G, and secretory IgA against FanC. The IgG2a and IgG1 titer assays revealed that immunization highly induced IgG2a compared to that of IgG1, indicating that T helper-1- related cell-mediated immune responses may be elicited by JOL950. The results show that both systemic and mucosal immunities against selected fimbrial antigens of bovine ETEC expressed by a live attenuated S. Typhimurium strain are prominently produced in mice immunized with JOL950 via an oral route.

  • Rotavirus and hepatitis A virus (HAV) spread by the fecal-oral route and infections are important in public health, especially in developing countries. Here, two antigenic epitopes of the HAV polyprotein, domain 2 (D2) and domain 3 (D3), were recombined with rotavirus VP7, generating D2/VP7 and D3/VP7, cloned in a baculovirus expression system, and expressed in Spodoptera frugiperda 9 (Sf9) insect cells. All were highly expressed, with peak expression 2 days post-infection. Western blotting and ELISA revealed that two chimeric proteins were antigenic, but only D2/VP7 was immunogenic and elicited neutralizing antibody responses against rotavirus and HAV by neutralization assay, implicating D2/VP7 as a multivalent subunit-vaccine Candidate for preventing both rotavirus and HAV infections.

  • Peripheral facial nerve palsy is a neurological condition/disease characterized by unilateral paralysis of the facial muscles. We report the effects of complex Korean medicine treatment in 2 patients diagnosed with Bell's palsy who developed symptoms 3-4 days following vaccination with ChAdOx1 nCoV-19 and who received oral steroids and antiviral medications. Complex Korean medicine treatments including acupuncture, electroacupuncture, bee venom acupuncture, cupping therapy, herbal medicine, and physical therapy were performed. Symptom improvement was evaluated daily using the Numerical Rating Scale, House-Brackmann Grade, and Yanagihara's Score. Patient 1 was hospitalized for 22 days and Patient 2 visited the outpatient clinic 20 times. In both cases, postauricular pain caused by Bell's palsy disappeared, and symptoms of facial paralysis improved following completion of treatment. These findings could suggest that combined Korean medicine treatment may improve symptoms of peripheral facial nerve palsy.

  • Acute hemorrhagic edema of infancy (AHEI) is a rare, benign, vascular condition that primarily affects infants, and is possibly associated with respiratory viral infections. A case involving a 47-day-old male infant, who was admitted with a 1-day history of fever, is presented. Initially, the patient developed an erythematous macular rash and patches on the hands and feet, along with swelling. The fever subsided after the first day of hospitalization, and the patient remained in generally good condition with normal oral intake. Timely recognition of AHEI is crucial to avoid unnecessary medical investigations or therapies, and to promptly identify any rare but potentially severe complications that may arise.

  • Purpose : To determine wether varicella can be prevented by administration of oral acyclovir(ACV) during the incubation period of the disease. Methods : Starting 9 days after exposure to the index case in their families, ACV(40 mg/kg/day in four divided doses) was given orally to 20 exposed children for 5 days. Their clinical features was compared with those of 20 control subjects. Antibody titers to VZV were measured in both group 1 week and 4 weeks after finishing the oral ACV administration. Results : The mean age of family members with varicella(51.4 months) were significantly high compared to that of ACV prophylaxis group(28.5 months) and control group(31 months) (P<0.05). Among the 12 children with ACV prophylaxis who completed follow up blood sampling, nine children were diagnosed as VZV infection on the serologic test(75%). Among them six children showed positive VZV IgM on the first blood sample and two children showed serocoversion to positive IgM on the second test after ACV prophylaxis. One child who was negative on both IgM and IgG, showed positive IgG on the second test. The incidence of fever and severity of skin rashes were significantly low in children received oral ACV than in the control group. No or reduced number of maculopapular eruption were observed in the oral ACV group compared to multiple vesicles of the control group. Conclusion : In the present study, we observed that oral ACV prophylaxis to the family contacts is effective in reducing severity of skin lesion. It is likely that oral ACV 9 days after contact prevents or reduces blood dissemination of VZV. Little is known about clinical effect and immunity to the virus in exposed children with no varicella symptom after treatment. We propose the checking up antibody to VZV some period after oral ACV, and considering vaccination to whom with no antibody. But further more studies are needed to practical application of oral ACV for the postexposure prophylaxis of varicella.
