PURPOSE: Headache is a frequent symptom in pediatric practice, but the prevalence of chronic recurrent headache was estimated in several studies with wide variations, because of inadequate expression and differences in case definition in children. Headache classification of International Headache Society is usually used in adults, but the application of it to children is uncommon, so we tried to diagnosis children with headache by using International Headache Society Classification. METHODS: We analyzed the clinical pictures, physical examinations including neurologic examination, PNS series, EEG and CT or MRI in 53 children with nonprogressing recurrent headache over than one month, who visited to pediatric department of Dong-A University hospital from January, 1995 to Feburary, 1996 and diagnosed them by using International Headache Society Classification. RESULTS: 1) The sex ratio between male and female was 1:1.2. 2) Diagnosed groups consisted of children with migraines in 22 cases(41.5%), tension-type headache in 19 cases(35.9%), coexisting migraine and tension-type headaches in 5 cases(9.4%), miscellaneous headaches not associated with structual lesion in 1 case(1.9%), headache associated with vascular disorders in 2 cases(3.8%), headache associated with nonvascular intracranial disorder in 1 case(1.9%), headache due to facial pain in 3 cases(5.6%). 3) Of 22 migraine cases, 13 cases(59.1%) had migraine with aura, 8 cases(40.9%) have migraine without aura and of 19 tension-type headache cases, 8 cases(42.1%) have episodic type, 11(57.9%) cases have chronic type. 4) Of 53 cases with recurrent headache, 3 cases(6%) had abnormal findings in CT or MRI. 5) Of 53 cases with recurrent headache, 9 cases(17%) had abnormal findings in EEG. CONCLUSIONS: International Headache Society Classifications are useful, but the diagnostic criteria are too strict for children, especially in migraine and tension type headache.

PURPOSE: There are so many causes of an altered mental status, including acute stroke and nonorganic causes. Making the differential diagnosis and the diagnostic approach for cases with an altered mental status represent a challenge to all emergency physicians. The serum S-100B protein concentration and the neuron-specific enolase (NSE) concentration have been used to evaluate brain damaged patients. We evaluated the usefulness of the serum S-100B protein concentration and the NSE concentration as screening tests for the patients with an altered mentality METHODS: Seventy-eight patients with an altered mentality were included in this prospective study. The patients were divided in two groups. One was the acute stroke group and the other was the non-organic cause group. We analyzed the serum S-100B protein and NSE concentrations of the two groups. We also assessed the correlation of the serum S-100B protein and NSE concentrations with the clinical and laboratory data of the two groups RESULTS: The serum concentration of S-100B was higher in the acute stroke group (median: 0.376, interquartile range: 0.18-1.05) than that in the nonorganic group (0.123, 0.087-0.307, p=0.000). The NSE level was also higher in the acute stroke group (median: 19.12, interquartile range: 14.42-27.19) than that in the non-organic group (13.71, 10.48-19.29, p=0.002). To differentiate the acute stroke group from the non-organic group, the sensitivity and specificity was 81.1% and 61.0%, respectively, at a cutoff value for the serum S-100B protein concentration of 0.14 microgram/L, and these were 81.1% and 51.2%, respectively, at a cutoff value for the serum NSE concentration of 13.71 microgram/L CONCLUSION: Our study suggests that the serum S-100B protein and NSE concentrations may be useful as screening markers for differentiating acute stroke from non-organic causes. However, further studies are needed to evaluate the relationship between the two proteins and the various diseases that have possibility to alter patients' mental status before these two proteins can be used clinically as screening tests.

BACKGROUND: This study examined the results of open wedge high tibial osteotomy with using an Aescula open wedge plate and an allogenic bone graft as a surgical technique for the patients who suffer from osteoarthritis of the knee with a genu varum deformity. METHODS: From March 2007 to August 2007, 33 patients (37 cases) with osteoarthritis of the knee and a genu varum deformity underwent a high tibial osteotomy with using an Aescula open wedge plate and an allogenic bone graft. The patients were followed up for more than 1 year. Before and after surgery, the correction angle of the genu varum was measured by the lower extremity scannogram and the posterior tibial slope, the joint space distance and the time to bone union were evaluated. The functional factors were evaluated using the Knee Society Score. RESULTS: The average knee score and function score improved from 52.19 +/- 11.82 to 92.49 +/- 5.10 and 52.84 +/- 6.23 to 89.05 +/- 5.53, respectively (p < 0.001). According to the lower extremity scannogram, the mean preoperative varus angle was -1.86 +/- 2.76degrees, and the average correction angle at the last follow-up was 10.93 +/- 2.50degrees (p < 0.001). The tibial posterior slope before surgery and at the last follow-up were 8.20 +/- 1.80degrees and 8.04 +/- 1.30degrees, respectively (p = 0.437). The joint space distance increased from 4.05 +/- 1.30 mm to 4.83 +/- 1.33 mm (p < 0.001). The average time to complete bone union was 12.69 +/- 1.5 weeks. CONCLUSIONS: An open wedge high tibial osteotomy using an Aescula open wedge plate and an allogeneic bone graft to treat osteoarthritis of the knee with a genu varum deformity showed good results for the precision of the correction angle, the time to bone union and the functional improvement.

PURPOSE: This study aimed to identify the true extent of non-responsiveness in full-term infants born from HBsAg-negative or HBsAg-positive mothers and vaccinated against hepatitis B virus (HBV) at 0, 1, and 6 months of age and to evaluate the effect of revaccination among non-responders. METHODS: The study included 716 full-term infants born in 2004-2007. Of 716, 662 infants (A group) were born to HBsAg- negative mothers and 54 infants (B group: 50, except HBsAg-positive infants) were born to HBsAg-positive mothers. All infants were administered DNA recombinant vaccines at 0, 1, and 6 months of age. B group infants received hepatitis B immunoglobulin at birth. Anti-HBs titers were tested at 7-12 and 9-15 months in A and B groups, respectively. Three revaccination doses were administered to non-responders whose anti-HBs titers were under 10 mIU/ml; revaccinated infants were retested at 1-3 months after last vaccination. The association between HBeAg seropositivity of mother and the failure of HBV immunoprophylaxis was evaluated. RESULTS: The seroconversion rates after primary hepatitis B vaccination were higher in A group (94.1%) than in B group (78%, P<0.001). The seroconversion rates were high in revaccinated infants (A group non-responders: 96.9%, B group non- responders: 87.5%). The failure of HBV immunoprophylaxis was significantly associated with maternal HBeAg seropositivity (P<0.001). CONCLUSION: The seroconversion rates after primary hepatitis B vaccination were low in B group infants. Revaccination of non-responders in B group was very effective. Therefore, anti-HBs testing and revaccination of B group is very important. Revaccination of non-responders in A group was also very effective. Thus, testing the immune status of infants born to HBsAg-negative mothers even after primary hepatitis B vaccination should be considered. However, to realize this, further studies on the cost-effectiveness of anti-HBs testing in healthy full-term infants are necessary.

The ORF5 gene encodes a major envelope glycoprotein (GP5), which is one of the three major proteins of porcine reproductive and respiratory syndrome virus (PRRSV). The GP5 protein has been known to be a 24.5-26kDa N-glycosylated envelope protein. The GP5 is involved in inducing neutralizing antibodies. For this reason, the GP5 is primary candidate for the PRRSV subunit vaccine. To produce the native form of GP5 in mammalian cells, we have cloned the ORF5 gene from PRRSV CNV-1 into the Semliki Forest virus (SFV)-based expression vector, resulting in recombinant pSFV-ORF5. By the infection with recombinant pSFV-ORF5 to BHK-21 cells, the GP5 expression was confirmed by immunocytochemistry and immunoblotting assay. The recombinant virus particle harboring ORF5 gene was infectious to BHK-21 and MARC-145. The RNA synthesis and expression of GP5 in the infected cell was also confirmed by RT-PCR.

PURPOSE: To assess the effectiveness of optimal treatment of proximal humeral fractures and humeral shaft fractures in elderly patients with osteoporosis using the Polarus nail. MATERIALS AND METHODS: Twenty-three patients with proximal humeral and humeral shaft fractures in elderly osteoporosis patients were treated using the Polarus intramedullary nail. Nine patients had proximal humeral fracture, 10 had humeral shaft fracture and 4 had the proximal humeral frac-ture extended diaphyseally. Radiological outcomes included the bone-union and the degree of re-sidual deformity. The residual deformities of the proximal humerus were assessed by the neck-shaft angle and the shaft angulation. Clinical outcome was assessed with the American Shoulder and Elbow Surgeons (ASES) score. RESULTS: All cases had bony union and the mean union period was 16.5 weeks. The average neck/shaft alignment at the time of bone union was 135degrees and varus deformities of neck-shaft angle was not seen in all patients. Varus shaft angulation was seen in 5 patients. The mean ASES score after surgery was 86.7 points. CONCLUSION: The Polarus intramedullary nail is effective for the treatment of proximal humeral and humeral shaft fractures in elderly patients with osteoporosis because it not only enables early postoperative mobilization, but also obtains bone-union without avascular necrosis and nonunion.

BACKGROUND: The lips have an asethetic and functional importance. There are various types of lip defects, and these are mainly due to tumor excision. Although there are numerous techniques available to repair the lips, no universal reconstruction method is presently available, and reconstruction of lip defects are inherently difficult. OBJECTIVE: To report surgical reconstruction results of lip defects. METHOD: Our study involved eleven patients, who had visited our dermatologic surgery clinic between 1995 and 2003, and had been histopathologically diagnosed as having either a basal cell carcinoma or squamous cell carcinoma on the lips. The medical records were reviewed, and clinical features, surgical methods, and cosmetic and functional results were evaluated. RESULTS: Wedge resection, resection with W-plasty, the subcutaneous pedicle flap, and dual mucosal flap technique were used to repair lip defects surgically. The vermilion border was aligned well in all the patients, and a post-operative scar was not apparent. However, a microstomia developed in one patient. CONCLUSION: The dermatologic surgeon should be familiar with various reconstruction options for lip defects. An appropriate choice depends on the size, location and depth of the defect. Specific functional and aesthetic aspects of the lips should be taken into account when planning and performing an operation.

PURPOSE:The purpose of this study was to determine the prevalence of asthma, allergic rhinitis, atopic dermatitis and allergic conjunctivitis among primary school pupils in Ilsan, Gyeonggi province. We also investigated change of symptoms after environmental control. METHODS:In April 2005, a cross-sectional study was performed among 2,745 1st to 6th graders of 3 primary schools in Ilsan, Gyeonggi province. International Study of Asthma and Allergies in Childhood (ISAAC) standardized questionnaires and additional questionnaires about environmental changes were distributed to their parents. RESULTS:Data were collected from 2,535 children (1,279 boys and 1,256 girls). The most common allergic symptom was rhinorrhea (43.0%), and atopic skin lesions, ocular lesions and wheezing were 24.5%, 19.7% and 18.2%, respectively. There was no significant relationship between allergic diseases and environmental status. One thousand four hundred nineteen children moved to a new place or had new interior decorations within the last 2 years. Of these children, 352 (24.8%) had allergic symptoms (OR=2.76, CI= 1.96-3.41, P=0.001). Interestingly, we found that children who had moved into apartments experienced more symptom changes than those who had not (P=0.022). CONCLUSION:The results of this study demonstrated that the prevalence of allergic conditions in primary school children in Ilsan, Gyeonggi province in 2005 was higher than those of nation-wide studies in 2000. We found the results of our study is similar to those of Seoul in 2005. We found a significant relationship between environmental status and changes of symptoms in primary school children in Ilsan, Gyeonggi province.
