The purpose of this study was to investigate whether there were any changes in taste sensitivity with recurrent aphthous ulceration. Nintyseven subjects(25 males and 72 females) were included for the study and they were categorized into 2 groups(recurrent aphthous ulceration 27 persons, control 70 persons), recurrent aphthous ulceration group was investigated in the department of Oral Medicine, College of Dentistry, Pusan National University from April, 2005 to August, 2006 and control group was investigated in the clinic at Incheon city from June, 2006 to August, 2006. The electrical taste thresholds were measured using an electrogustometer of the 4 different sites(tongue tip, tongue lateral, circumvallate papilla and soft palate) in oral cavity. The results were as follows ; 1. The electrical taste threshold showed significant lower in the RAU group. 2. The electrical taste threshold showed significant lower in female group, and showed significant lower except soft palate in male group of the RAU group. 3. The electrical taste threshold showed a tendency to increase in all site of the multiple RAU group, but there were no significant differences. 4. The electrical taste threshold showed a tendency to increase in tongue lateral of the acute RAU group, and showed a tendency to increase in tongue tip, circumvallate papilla, soft palate of the chronic RAU group. 5. After treatment, electrical taste threshold was significant increase than initial visit in the RAU group. 6. After treatment, NAS showed a tendency to decrease in the RAU group.

Infantile hypertrophic pyloric stensosis(IHPS) occurs in three of 1000 live births, and is a major cause of nonbilious vomiting of early infancy. It's etiology and pathogenesis however are still obscure. The operation of pyloromyotomy described by Ramstedt in 1912 remains the standard treatment. From January 1990 to July 1997, 64 infants with IHPS were treated at the Department of Pediatric Sursery, Yeungnam University Hospital. The ratio of male to female was 7:1, and the most prevalent age ranged from 2 weeks to 8 weeks(81.2 %) of age. Fifty-seven infants were first born (57.8 percent). The body weight of all patients at admission was below the 50 percentile. Age of onset of symptoms was between 2 and 4weeks of age in 23 cases(35.9 %). All infants had a history of nonbilious vomting, generally projectile in nature. Hypokalemia was noted in 14 cases(21.9 %) and hypochloremia in 26 cases(40.6 %). In the preoperative ultrasonography, the average muscle thickness, diameter, and length of the pylorus were 6.3 mm, 12.3 mm, and 17.8 mm. A total of 13 associated anomalies were noted in 12 patients. All cases were treated with Fredet-Ramstedt pyloromyotomy. Postoperative wound infection occured in 3 cases. Thirteen cases(20.3 %) presented intermittent nonprojectile vomiting after operation. With control of oral intake vomiting subsided within one week in 63 patients, and in thirteen days in another.

Purpose : The purpose of this study is to analyze the epidemiologic characteristics of sudden unexpected death in infancy and to evaluate the importance of postmortem autopsy. Methods : We reviewed, retrospectively, medical records of 34 infants admitted to Kangnam General Hospital from January 1987 to December 2001 because of sudden unexpected death. We investigated the cause of death through medical history, death scene examination, autopsy findings, acylcarnitine and organic acid analysis. Results : Among the total 34 infants, 18 were male(52.9%) and 16 were female(47.1%). Thirty infants(88%) were below the six months of age. Winter was the most affected season(38.2%). Eighteen infants(52.9%) died between 6 and 12AM. The prone sleeping position was observed more frequently than the supine position at death; nine cases in the prone position, six cases in the supine position. The cause of death of 23 cases could not be found by only history and death scene examination. Autopsy was done in 13 cases. Seven cases of them were thought to be SIDS. In six cases, we explained the cause of death with autosy findings. They were an endocardial fibroelastosis, a nesidioblastosis, a subdural hematoma, a bronchopneumonia and two fatty changes of liver. Metabolic screening tests performed in three cases to rule out metabolic disorder since 2000 were all normal. Conclusion : We concluded that autopsy and metabolic screening test should be performed to find out the cause of death in sudden unexpected death in infancy.

Purpose: To evaluate the prevalence and clinical manifestations of various glomerulonephritis (GN) in children, a clinicopathological anlysis of 310 biopsied cases were performed. Method: We conducted retrospective study with review of histopathologic findings and clinical manifestations of the 310 cases diagnosed as glomerulonephritis by percutaneous renal biopsy which were done between January 1986 and December 1996 at department of pediatrics, Pusan Paik hospital. Results: 1) Male to female ratio was 1.54:1 and the range of age was from 13 months to 15 years 10 months. 2) Among these, 217 (70.0%) patients were belong to primary GN and 93 (30.0%) patients were belong to secondary GN. As a whole, the most common pathologic diagnosis was minimal change lesion (MC, 32.6%), which was followed by IgA nephropathy (IgAN, 15.8%), $Henoch-Sch\"{o}nlein$ purpura nephritis (HSPN, 13.5%), Poststreptococcal glomerulonephritis (PSAGN, 8.1%). 3) Clinical manifestations of patients were asymptomatic urinary abnormality (43.2%), nephrotic syndrome (41.0%), acute glomerulonephritis (14.2%), chronic glomerulonephritis (1.0%), rapidly progressive glomerulonephritis (0.6%). 4) In primary GN, the most common pathologic diagnosis was MC (46.5%), IgAN (22.6%), thin glomerular basement membrane (GBM) disease (7.8%), membranoproliferative glomerulonephritis (MPGN, 5.5%), mesangial proliferative glomerulonephritis (MesPGN,4.6%), focal segmental glomerulosclerosis (FSGS, 4.6%), membranous nephropathy (MN, 0.9%), sclerosing glomerulonephritis (SCGN, 0.9%), crescentic glomerulonephritis (CreGN, 0.5%) and non-specific glomerulonephritis (NonspGN, 6.0%). 5) Major causes of secondary GN were HSPN (45.2%), PSAGN (26.9%), hepatitis B associated glomerulonephritis (HBGN, 17.2%), lupus nephritis (LN, 6.5%), Alport syndrome (2.2%), hemolytic uremic syndrome (1.0%), fibrillary glomerulonephritis (1.0%) in descending order. Conclusions: There are some differences of the results of clinicopathological stuidies of glomerulonephritis in children because of its different indications of renal biopsy, pathologic classification of renal disease and methods of analysis among investigators. In order to establish more reliable data of incidence and classification of childhood glomerulonephritis in Korea, multicenter cooperative study were necessary.

Aim: Disc displacement without reduction of the temporomandibular joint (TMJ) has been managed by mandibular manipulation to reduce the displaced disc but with a low success rate. The purpose of this study was to determine whether auriculotemporal nerve block anesthesia had an effect on the reduction of the displaced disc and to analyze the factors that influenced the result. Methods: 112 patients were diagnosed with disc displacement without reduction and treated by mandibular manipulation. Disc was recaptured in 35 patients. Among the 77 patients with whom disc recapture had failed, the auriculotemporal nerve was blocked with a local anesthetic in the 49 patients (mean $age \;{\pm}\; SD\; =\; 34.4\;{\pm}\; 15.1$; male 24, female 25) and then mandibular manipulation was performed again. Factors including age, elapsed time from the onset, and opening amount were analyzed in association with disc reduction rate with the auriculotemporal nerve block. Results: Among 49 patients who did not respond to manipulation only, manual reduction with auriculotemporal nerve block anesthesia was successful in 19 patients (38.8%). Maximum unassisted opening amount significantly increased in the 19 patients with successful recapture of the disc ($mean \;{\pm}\; SD\; =\; 46.1 \;{\pm}\; 4.5\; mm$), in contrast to the limited opening amount of the 49 patients before local anesthesia of the auriculotemporal nerve ($mean \;{\pm}\; SD\; =\; 25.7 \;{\pm}\; 6.0\; mm$). Age, elapsed time after the onset, and preoperative opening amount were not associated with the reduction rate. Conclusion: The results of this study suggest that auriculotemporal nerve block anesthesia increases the reduction rate of the disc displacement without reduction of the TMJ when combined with mandibular manipulation, and such anesthesia should be applied at the first stage of manual treatment of disc displacement without reduction.

Purpose : $Henoch-Sch\"{o}nlein$ purpura(HSP) is usually a self-limited disease with a good eventual outcome. The prognosis of HSP is mainly determined by the renal involvement. In this study, We evaluated children with biopsy-proven $Henoch-Sch\"{o}nlein$ purpura nephritis about the clinical outcome correlated with renal manifestation and morphologic findings. Methods : The clinical features, initial laboratory and pathologic findings, and clinical out-come were evaluated in 60 children with biopsy-proven $Henoch-Sch\"{o}nlein$ purpura nephritis at Yonsei University Severance Hospital during the period from Jan. 1990 to Dec. 2002. Results : The ratio of male to female patients was 1.2:1. The interval between the onset of $Henoch-Sch\"{o}nlein$ purpura and renal manifestation was less than 3 months in 81% of the patients. Initial renal manifestation was microscopic hematuria in 100% of patients, isolated hematuria in 15%, acute nephritic syndrome in 7%, nephrotic syndrome In 22% of patients. Renal manifestation correlated with clinical outcome. Grade II and III were the most common in histologic grades of ISKDC. Renal pathologic finding correlated with clinical outcome. Conclusion : Renal manifestation and pathologic findings correlated with the clinical out-come. It is necessary to evaluate the correlation between pathologic findings and treatment.

Purpose: The purpose of this study was to evaluate the diagnostic accuracy of Tc-99m labeled antigranulocyte antibody immunoscintigrapy in the diagnosis of osteomyelitis and compare with the results of triphasic bone scan. Materials and Methods: The study population was 39 patients (22 male, 17 female) who had uncertain diagnoses of osteomyelitis. Fifteen patients had history of orthopedic surgery, and 5 had previous fracture. One milligram of monoclonal antibody against NCA-95 was labeled with 370 MBq of Tc-99m, injected intravenously, and 4 hour images were obtained. Triphasic bone scan images were obtained in 30 patients. The final diagnosis was confirmed by bacteriologic culture, biopsy or long term clinical follow up. Results: Twenty one patients were confirmed to have osteomyelitis (1 acute, 20 chronic). Eighteen patients were without osteomyelitis. Antigranulocyte antibody immunoscintigraphy had a sensitivity of 71% (15/21), and a specificity of 89% (16/18), while the sensitivity and specificity of triphasic bone scan was 93% (13/14) and 38% (6/16), respectively. Antigranulocyte antibody scan showed higher specificity of 100% (11/11) in comparison with 33% (3/9) of triphasic bone scan in patients with history of orthopedic surgery or fracture. Conclusion: Antigranulocyte antibody immunoscintigraphy is more specific than that of triphasic bone scan and may be helpful in patients with history of surgery or fracture. However, sensitivity is lower than triphasic bone scan in the detection of chronic osteomyelitis.

An outbreak of typhoid fever in Samchunpo city was surveyed and the results were summarized as follows: 1. 638 of clinical cases were detected in 17 Dongs(districts) of the city of Samchunpo,(54,064), during the epidemic period from 1st September to the end of November, 1967. 2. The morbidity rate was 1,189 per 100,000 population;(1,300 female, and 1,060 male). 3. The highest peak was reached in the third week of September and a second peak appeared at the end of September 1967. 4. The mode of infection was suspected strongly as a water-borne and the source of infection as an old public well called Gal-Dae-Saim, since the causative agent was found in close public latrine and the contaminated sewage ditch witch was connected with the well. 5. All patients and carriers were treated at their home under the supervision of local medical authorities. 6. The Gal-Dae-Saim was closed immediately on 7th October, 1967 by the order of the mayor. 7. At the end of November, 1967 when the outbreak in Samchunpo was almost ended, another small epidemic occurred in Koseong county which bordered the eastern outskirt of the city. 8. During the survey, a strain of Shigella flexneri was isolated from the sewage located three meters from Gal-Dae-Saim and also from one case. 9. It was reported by the local health center in May, 1968, that no carrier had been detected in the survey made among the persons who had had typhoid fever in 1967. Also thereafter no cases of typhoid fever were reported through October, 1968.

Background : Pulmonary tuberculosis with a remaining cavitary lesion is considered to be a problem with the course of treatment. In particular, re-treatment cases tend to respond poorly to current anti-tuberculosis agents. Therefore the factors that are related with the poor closure of a cavitary lesion in pulmonary tuberculosis during treatment were evaluated. Methods : A retrospective review of the medical records and chest X -ray films of 68 patients who had chemotherapy for the pulmonary tuberculosis with cavitary lesions was made. All the patients had been followed up for more than 12 months at National Masan Tuberculosis Hospital as of Aug. 2000. Results : The male to female ratio was 3.9:1.72.4% of the patients were between 20 to 50 years of age. 66.2% of the cavitary lesions on the chest X-ray films were confined to the upper lung fields : 36.8% in the right upper lung field and 29.4% in the left upper lung field. 82.4% of the cavities were less than 40 mm in their size, and 83.8% were less than 6 mm thick. The cavitary lesions were closed in 48 cases and remained in 20 cases during a follow-up period of more than 12 months. The factors that are thought to affect to the outcomes of the cavities were age, past medication history, the number of unused drugs, and the number of sensitive drugs. Conclusion : In the treatment courses of pulmonary tuberculosis with cavitary lesions, the following factors are associated with less desirable outcome:an age over 45, a past medication history of more than 2 courses of treatment, The number of unused drugs not exceeding average 6 and the number of sensitive drugs not exceeding average 7.

Elasticity and softness of the skin depend on the level of moisture present in the stratum corneum, which is known to be affected by various environmental changes, such as cold and hot winds and dry environments. However, not many studies have been conducted on changes in skin moisture and the degree of recovery due to individual skin differences. In the present study, we aimed to investigate the effect of warm air heating on skin hydration levels and develop moisturizing formulas to improve lowered skin hydration levels. In order to deliver warm air heating condition, heating dryer (40 ℃, 6 m/s, 30 cm apart from forearm) was applied into inner forearm of healthy subjects (male: 10, female: 39, age: 25 - 63) Among 49 subjects, 26 subjects showed significantly lowered skin hydration levels until 30 min after warm air heating exposure (lowered group). In addition, moisturizing cream with high water holding capacity was applied to forearm of 10 subjects in lowered group for 3 weeks and skin hydration levels after warm air heating were significantly improved at the levels of before application of warm air heating. From this study, we found out that there is a skin type that skin hydration levels are significantly decreased under warm air heating condition (dehydrated skin) and this dehydrated skin can be improved by moisturizing formulas with high water holding capacity.
