Midline craniofacial dermoids are rare lesions resulting from the abnormal fusion of embryologic structures. The clinical features of craniofacial dermoid cysts show a range of presentations, including infection, asymptomatic puncti, or seizure secondary to intracranial invasion. Appropriate management involves an accurate diagnosis of the dermoid cyst and a complete resection.

PURPOSE: To know the true carrier rate and the immunologic responses (antistreptolysin O :ASO) to beta-hemolytic streptococci which obtained from normal school children with or without carrying streptococci. And to study the clinical meaning of the number of organisms found in culture. METHODS: One hundred ninty-eight first grade of elementary school children were included. I obtained throat swab culture from tonsil and tonsilar fossa with sterile cotton ball stick and plated on sheep blood agar dish, counted number of colonies of beta-hemolytic streptococci (BHS) after overnight incubation, examined ASO titer (Rantz-Randall method) simultaneously, and differentiated grouping of BHS with Streptex. RESULTS: 1) Of the 198 normal school children, 34 (17.2%) had cultured BHS. 16 (8.1%) were group A, 4 (2.0%) were group C, 2 (1.0%) were group G, and 12 (6.1%) were non-grouping BHS. 2) 14 (22.2%) out of 63 normal children without carrying BHS and 16 (47.1%) out of 34 with carrying BHS had come out above 250 units of ASO. 13 (59.1%) out of 22 group A,C,G streptococcal carriers had showed above 250 units of ASO. The true carrier rate of BHS were 18 (9.0%) out of 198 elementary school children. 3) When I had counted the number of colonies from 34 carrier of BHS, 1+ was 67.6% and 2+ was 17.6%. It was 85.2% of total children with carrier. 4) There were significant differences between the mean titer of logarithmic ASO obtained from group A BHS carrier and that of normal children without carrying BHS (P=0.001), and differences between that of group A and group B,C,G streptococci (P= 0.0005). CONCLUSIONS: The ASO titer obtained from BHS carrier is higher than normal school children, which suggests the possibility of subclinical infection, the possibility of persistent habor of organism since past infection had contracted, and the possibility of replaced old organism in past infection with new organism. It should be performed follow-up study for identifying the persistence of immunologic response in accordance with or without culturing organism.

A 3-month-old asymptomatic infant presented with bilateral extensive consolidation of the lungs, which was diagnosed as pulmonary tuberculosis. Evaluation of the baby for tuberculosis was initiated because of a history of contact with a known tuberculosis patient. This case is interesting because the baby rarely showed symptoms during the whole course of the disease.

Immune reconstitution syndrome (IRS) in HIV-infected patients is an adverse consequence of the restoration of pathogen-specific immune responses during the initial months of highly active antiretroviral treatment(HAART). Previously subclinical infections are unmasked or pre-existing opportunistic infections clinically deteriorate as host immunopathological inflammatory responses are switched on. While the eye is the area where Cytomegalovirus(CMV)-associated IRS occurs most often in patients with AIDS, it also can present with intestinal or pulmonary involvement. We present a case report of an HIV-infected patient in whom CMV enterocolitis and jejunal perforation developed after HAART.

Adiaspiromycosis is caused by pulmonary infection with Emmonsia. Inhalated spores of Emmonsia cause asymptomatic infection to necrogranulomatous pneumonia, depending on the burden of adiaspore and host immunity. For disease monitoring of wild rodents captured on Jeju Island in Korea, we examined the lung tissue of wild rodents histopathologically. Spores composed of thick three-layered walls were found following histopathological examination and were diagnosed as adiaspiromycosis. Adiaspiromycosis has been found in mammals in many parts of the world. To our knowledge, this is the first report of adiaspiromycosis of an Apodemus agrarius captured in Korea.

In order to evaluate the clinical usefulness of maternal serum C-reactive protein measurement in early detection of infectious morbidity at term laboring women, serum C-reactive protein levels were measured in 521 healthy pregnant women : 64 who were not in labor before term, 55 who were in labor before term, 71 who were not in labor at term and 331 who were in labor at term. The frequencies of elevated serum C-reactive protein level were compared in relation to the gestational weeks, the presence or absence of labor, the status of amniotic membranes and the degree of cervical dilation. The obtained results were as follows. 1. The frequencies of women with elevated serum C-reactive protein, 0.8 mg/dl or higher and 2.9 mg/dl or higher, in 521 health pregnant women were, 12 % and 4 %, respectively. 2. C-reactive pretein levels of 0.8 mg/dl or higher were more frequent in the group of women in labor than those not in labor(5. 93 %, vs, 13.73 %, p<0.05), but the frequencies of C-reactive protein level of 2.0 mg/dl or higher were not statistically different between both groups. The frequencies of C-reactive protein level of 0.8 mg/dl or higher and 2.0 mg/dl or higher were not statistically different between the groups before term and at term, intact and ruptured membranes, latent phase and active phase of labor, respectively. 3. Before term, C-reactive protein levels of 0.8 mg/dl or higher and 2.0 mg/dl or higher were more frequent in the group of women in labor than those not in labor(23.64 vs. 4.69, p<0.001 and 12.73% vs. 3.13%, p<0.05, respectively), but those statistical differences were not seen between both group at term. Above results and review of literature suggest that serum C-reactive protein level of 2.0 mg/dl or higher may be reliable in early detection of infectious morbidity at term laboring women as well as laboring women before term, and the presence of subclinical infection should be suspected in the laboring women before term with serum C-reactive protein level of 0.8 mg/dl or higher.

Although throat culture is a gold standard to diagnose group A streptococcal (GAS) pharyngitis or its sequelae, antistreptolysin O (ASO) is useful to confirm the diagnosis. In case there is no elevation of ASO, it is necessary to add one or more serologic tests, such as antideoxyribonuclease (ADNase) B test. ADNase B levels were analyzed in the carriers of beta-hemolytic streptococci (BHS) in this study. ADNase B concentrations were determined quantitatively by nephelometry (Behring Nephelometer 100 Analyzer, Germany) on 157 sera of healthy elementary school children in Chungnam who were positive of BHS in the throat culture. ASO levels were measured previously by autoanalyzer (Hitachi 747, Japan). Mean ADNase B and ASO levels were compared according to serological group of BHS and number of colonies. The carriers of GAS had significantly higher ADNase B levels (mean 453 IU/ml) than those of non-A beta-hemolytic streptococci (NGAS, 278 IU/ml), while the difference of ASO levels between GAS (482 IU/ml) and NGAS (350 IU/ml) carriers was not so high. The carriers who had more than 10 CFU of BHS had significantly higher ADNase B or ASO levels than those who had less than 10 CFU. The correlation between ADNase B (Y) and ASO (X) was Y=0.4X+229 (r2=0.13). ADNase B test could discriminate GAS from NGAS more effectively than ASO test. The carriers who have more than 10 CFU might undergo asymptomatic infection, as their ADNase B or ASO levels were significantly high. Because distribution of ADNase B showed little correlation to that of ASO, ADNase B test could be used as a supplementary test to diagnose GAS infection.

Although the incidence of tuberculosis in Korea in general has declined in recent years, it remains an importat health problem, especially in children. Inspite of the recent controversy over the necessity of tuberculin skin test prior to measles vaccination, this brief report shows 13.8% of positive skin test at 9 and 15 months of age at the time of measles vaccination. We feel, in Korea, practicing tuberculin skin test prior to measles vaccination is good way of detecting asymptomatic infection in young age who needs preventive therapy.
