PURPOSE: The reported clinical manifestations in Turner syndrome were different by karyotypes, countries and races. So, We evaluated the physical findings & medical problems in patient with Turner syndrome according to karyotype. METHODS: We examined prospectively 53 cases that diagnosed as Turner syndrome by chromosome study at the Pediatric Endocrine Clinic, YUMC from May 1999 to Aug 1999. According to the karyotype, they were divided into 3 groups:45, X(22 cases, 41.5%), mosaicism(18 cases, 34%) and structural aberration group(13 cases, 24.5%), and 53 cases were reevaluated by prepared protocol of 22 abnormal physical findings and 4 medical problems. Chi-square test was used for statistic analysis. RESULTS: 1)In case of 45, X group, they had short stature(100%), cubitus valgus(95.5%), widely spaced nipples(86.4%), shield chest(72.7%), low posterior hair line(68.2%), in case of mosaicism group, they had short stature(100%), cubitus valgus(72.2%), high arched palate(66.7%), widely spaced nipples(61.1%), short neck(61.1%) and in case of structural aberration group, they had short stature(100%), high arched palate (92.3%), widely spaced nipples(92.3%), low posterior hair line(76.9%), shield chest (76.9%), in frequency order. Short stature was the most common finding in Turner syndrome. The incidence of high arched palate was significantly higher in structural aberration group(P<0.05). 2)In case of 45, X group, they had otitis media(63.6%), thyroid problem(4.5%) and no renal problem and cardiac problem, in case of mosaicism group, they had otitis media(38.9%), thyroid problem(5.6%) and no renal problem and cardiac porblem and in case of structural aberration group, they had otitis media(61.5%), thyroid problem(15.4%), renal problem(7.7%) and cardiac problem(7.7%) in frequency order, they had no statistical difference in among three groups. CONCLUSION: In case of 45, X group, the incidence of cubitus valgus, webbed neck were more common findings and of high arched palate, micrognathia were less common findings compared to other group. In case of mosaicism group, the incidence of micrognathia, epicanthal fold were more common findings and wide spaced nipples, antimongoloid fissure were less common findings compared to other group. In case of structural aberration group, the incidence of high arched palate is most common finding among 3 group(P<0.05) and pigmented nevi and epicanthal fold were less common findings compared to other group. The incidence of medical problems such as otitis media and thyroid problem were than other foreign country reports.

Natural killer T (NKT) cell is a special type of T lymphocytes that has both receptor of natural killer (NK) cell (NK1.1, CD161c) and T cell (TCR) and express a conserved or invariant T cell receptor called Valpha14Jalpha18 in mice or Va24 in humans. Invariant NKT (iNKT) cell recognizes lipid antigen presented by CD1d molecules. Marine-sponge-derived glycolipid, alpha-galactosylceremide (alpha-GalCer), binds CD1d at the cell surface of antigen-presenting cells and is presented to iNKT cells. Within hours, iNKT cells become activated and start to secrete Interleukin-4 and interferon-gamma. NKT cell prevents autoimmune diseases, such as type 1 diabetes, experimental allergic encephalomyelitis, systemic lupus erythematous, inflammatory colitis, and Graves' thyroiditis, by activation with alpha-GalCer. In addition, NKT cell is associated with infectious diseases by mycobacteria, leshmania, and virus. Moreover NKT cell is associated with asthma, especially CD4+ iNKT cells. In this review, I will discuss the characteristics of NKT cell and the association with inflammatory diseases, especially asthma.

PURPOSE: Interleukin 18(IL-18) is a potent proinflammatory cytokine which induces IFN-gamma, GM-CSF, TNF-alpha and IL-1, to activate killing by lymphocytes, and to up-regulate the expression of certain chemokine receptors. Kawasaki disease (KD) is an inflammatory disease which increases serum levels of inflammatory cytokines, such as TNF-alpha and IL-6. This study was performed to examine the serum levels of proinflammatory cytokine IL-18 in KD. METHODS: Twenty patients with KD and 10 healthy children were enrolled in this study. Serum levels of IL-18 and TNF-alpha from the patients with acute and subacute stage of KD and normal controls were measured by using ELISA. Acute phase reactants such as ESR and C-reactive protein were measured during the acute stage of the disease. RESULTS: There was a significant increase in serum levels of IL-18 measured at the acute stage of KD(818.0+/-253.4 pg/mL) compared with those of subacute stage (367.7+/-140.1 pg/mL) (P<0.01) and normal controls(348.6+/-122.9 pg/mL)(P<0.01). However, the increase of IL-18 was not correlated with the increase of TNF-alpha(R=-0.156, P=0.488) or other acute phase reactants. CONCLUSION: The results showed that IL-18 was increased during the acute stage of KD, but the increase of IL-18 was not directly correlated with TNF-alpha. This results suggest that Il-18 is not a useful marker to estimate the severity of inflammation in KD.

PURPOSE: The aim of this study was to investigate the clinical characteristics of Respiratory syncytial virus (RSV) infection during the neonatal period to provide information that is useful in clinical practice and suggest extension of the palivizumab administration. METHODS: Neonates admitted to the National Health Insurance Service Ilsan Hospital neonatal intensive care unit due to respiratory symptoms and for whom multiplex reverse transcription-polymerase chain reaction and multiplex real time-polymerase chain reaction tests were performed between October 2011 and May 2016 were included in this study. Medical records were retrospectively reviewed, and data was collected for 156 neonates. RESULTS: Among the 156 neonates, RSV was detected in 114 (73.1%), non-RSV in 25 (16%), and no virus in 17 (10.9%). The majority were full term infants (92.4%) and peak incidence of RSV infection was in January. Post-natal care center infection was more common in the RSV group (46.6%) than that in the other virus groups (24%, P=0.0243). Clinical symptoms were severe in the RSV group in contrast to that in the non-RSV or others groups. The RSV group frequently needed oxygen therapy (P=0.0001) and the duration of hospital stays were longer (P=0.0001). CONCLUSION: RSV is a significant cause of respiratory infection in neonates and the severity is higher in contrast to that with other viral causes of infection. Infants in post-natal care centers have a high-risk of developing RSV infections; therefore, palivizumab administration may be considered in this group to prevent hospitalization and reduce the duration of hospital stay.

The current paper reports on a case of subdural empyema secondary to frontal sinusitis in an otherwise healthy child. Sinusitis is a common and benign condition in most pediatric cases. Because of the widespread use of antibiotics, intracranial extension of pediatric sinusitis is rarely seen today; however, complications (e.g., cavernous sinus thrombosis, orbital infection, meningitis, and subdural empyema) are potentially life threatening. A 15-year-old right-handed male presented with a 3-day history of fever, headache, and left-sided palsy. Computed tomography revealed right-sided subdural empyema with right frontal sinusitis and maxillary sinusitis. A postoperative inpatient neurological consultation was requested 2 months post-surgery due to motor function deficits. The results suggested that early and accurate diagnosis of subdural empyema leads to prompt treatment and a favorable outcome for the patient.

Eczema herpeticum is a disseminated herpes simplex virus infection mainly in atopic individuals. Low expression of cathelicidin in atopic dermatitis contributes to the lack of defense capability against viral infection. Serum vitamin D level, which is essential for cathelicidin induction, is reported to be low in patients with severe atopic dermatitis. However, serum vitamin D level has not been studied in patients with eczema herpeticum. The mainstay of treatment of eczema herpeticum is systemic antiviral therapy. In atopic individuals with eczema herpeticum, intravenous immunoglobulin is less likely to enhance cutaneous viral susceptibility than other immunomodulators. Herein, we report two pediatric cases of widespread eczema herpeticum, both accompanied by high fever and low serum vitamin D levels. The patients were successfully treated with intravenous acyclovir and intravenous immunoglobulin. Serum 25-hydroxyvitamin D3 level was even less than 4.0 ng/ml in one patient, and no more repeated episodes of eczema herpeticum occurred, after supplementation of vitamin D.

Mastocytosis is rare disorder characterized by the overproliferation and accumulation of tissue mast cells and spontaneous regression before adolescence in childhood, almost. Clinical features are vary and depend on local accumulation of mast cells in different organs and the effects of their mediators. Mast cell disease is commonly involved in the skin, and occasionally gastrointestinal tract, bone marrow, liver, spleen and lymphoid organs as well. Mastocytosis occurs equally in persons of each gender and it affects all age groups. The incidence is unknown and familial tendency is unusual. We are reporting a case of mastocytosis confirmed by skin biopsy who was visited for skin lesions that skin rashes at 10 days after birth, change to bullar at 3 month later.

Tumor necrosis factor (TNF) -alpha plays a major role in the pathogenesis of Kawasaki disease (KD), a systemic vasculitis primarily affecting young children. We performed this study to examine the serum levels of TNF-alpha and to investigate a possible relation to promoter polymorphism at positions -238 and -308 in KD patients in Korea. We obtained 48 paired serum samples from 24 patients in the acute and subacute stages of KD, and control sera from 12 age-matched children who were having routine blood samples taken before elective surgical procedures. Our studies showed a significant increase in serum levels of TNF-alpha measured in the acute stage of KD (24.1+/-9.4 pg/mL) compared to those in the subacute stage (11.8+/-5.8 pg/mL; p < 0.01) and normal controls (10.4+/-4.9 pg/mL; p < 0.01). Previous studies report that the presence of the A allele at positions -308 and -238 may be associated with higher TNF-alpha levels. However, our results showed that the frequency of the A allele at position -308 in the KD patients was the same as the controls (2 out of 24, 8.3% vs. 8.3%, odds ratio (OR) = 1.00), while the frequency of the A allele at position -238 in the KD patients was lower than the controls (0/24, 0% vs. 8.3%, OR=0.00) ; this difference though was not statistically significant. We concluded that although TNF-alpha levels were significantly elevated in the acute stage of KD, there was no significant difference in the frequency of the A allele at positions -238 and -308 between the KD and control groups in Korean patients.
