OBJECTIVES: This study aimed to investigate differences in unmet dental care needs according to employment status and if factors have relevance to unmet dental care needs due to "economic burden" and "no time to spare for visiting". METHODS: Multivariate logistic regression analysis was performed to examine the factors that affected the prevalence of unmet dental care needs due to "economic burden" and "no time to spare for visiting" in an economically active population comprised of subjects aged 20-64 years. RESULTS: Compared to regular workers, part-time workers experienced 1.28-times more unmet dental care needs, while students experienced 0.64-times fewer unmet dental care needs. With regard to reasons related to "economic burden", the rate of experiencing unmet dental care needs was 1.37-times higher for part-time workers than for regular workers. Regarding reasons related to "no time to spare for visiting", the rate of experiencing unmet dental care needs was 0.51-times lower in part-time workers compared with regular workers. In economically inactive people, these values were 0.51-times lower in the unemployed, 0.37-times lower in students, 0.23-times lower in house workers, 0.20-times lower in subjects with disease and injury, and 0.20-times lower in early retirees compared to regular workers. CONCLUSIONS: Part-time workers experienced more unmet dental care needs compared with regular workers. With regard to "economic burden", a significant difference in unmet dental care needs was observed between regular workers and part-time workers. Additionally, regarding "no time to spare for visiting", people who were economically inactive because of unemployment, student or house-worker status, diseases and injury, and retirement experienced fewer unmet dental care needs compared with regular workers.

BACKGROUND: Helicobacter pylori(H. pylori) has been implicated in the pathogenesis of chronic active gastritis and peptic ulcer disease. All patients with ulcers who are infected with H. pylori receive antimicrobial therapy. Therefore diagnosis of H. pylori infection is imperative for the treatment gastritis or ulcer patients. We evaluated the four diagnostic methods and three culture media for the isolation of H. pylori. MATERIALS AND METHODS: Rapid urease test(CLO test), modified Gram stain, culture, and nested polymerase chain reaction (PCR) were performed with 108 gastroscopic biopsy specimens from patients with peptic ulcer or chronic gastritis. Among them 40 specimens were inoculated onto each of 5% sheep blood agar, e99 Yolk emulsion (EYE) agar, and 7% horse blood agar containing antibiotics. RESULTS: The positive rates were the highest by the PCR(72%), 67% by modified Gram stain, 64% by CLO test, and 57% by culture. Among the three media the horse blood agar (selective medial) gave the highest isolation rate (48%), followed by sheep blood agar (45%), and EYE agar (38%). CONCLUSION: Though PCR was the most sensitive method for the detection H. pylori modified Gram stain was sensitive enough, simple, rapid, and economical as the routine diagnostic method of H. pylori. For the culture of H. pylori combination of sheep blood agar as nonselective media and horse blood agar as selective media would show the highest isolation rate.

The purpose of the present study were to disclose whether the depth of the mandibular antegonial notch can be used as an indicator of mandibular growth potential. The patients composed of 76 samples and were classified following 3 groups, based on the depth of mandibular antegonial notch: Deep notch group (more than 3mm), Neutral notch group (1-3mm), Shallow notch group (less than 1mm). For each case, the first lateral cephalograms were taken prior to the start of treatment and the second films 3-4 years after. The results were as follows; 1. Deep notch group had a shorter corpus, less ramus height and greater gonial angle than did Shallow notch group. 2. Deep notch group had a more retrusive mandibular position than Shallow notch group. 3. Deep notch group had longer total anterior facial height and longer anterior lower facial height group. 4. Deep notch group grow vertical clockwise growth pattern, while Shallow notch group grow horizontal counterclockwise growth pattern. 5. Deep notch group had less mandibular growth than Shallow notch group during observation period.

Protein-calorie malnutrition is common in CAPD patients and is associated with increase in morbidity and mortality in CAPD patients. There are many causes of malnutrition in CAPD patients, and it is well known that a large amount of protein losses through peritoneal membrane is one of them. To investigate the effect of the peritoneal membrane transport characteristics on the nutritional status in long-term CAPD patients, we conducted a cross- sectional study on clinically stable 115 patients (63 males and 52 females) who have been on CAPD for more than 2 years, and assessed nutritional status by subjective global assessment (SGA), biochemical, anthropometric and urea kinetic parameters. Patients were divided into 4 groups according to the results of standard peritoneal equilibration test (PET). The results were as follows: 1) The patients were divided into 4 groups according to the PET results: high transporter (n=16, 14%), high average transporter (n=38, 33%), low average transporter (n=50, 43%), and low transporter (n=11, 10%). 2) The mean age of the patients was 50.1+/-11.6 years (range, 19-75) with sex ratio (M:F) 1.2:1 and mean duration of dialysis was 57.5+/-27.8 months (range, 24-135). The mean body weight (Bwt) was 59.2+/-8.9kg, percent ideal body weight (%IBW) was 104.7+/-15.6%, %lean body mass (LBM)/Bwt was 82.1+/-11.1%, and malnourished patients by subjective global assessment (SGA) were 32.2% (38/115). 3) The mean BUN, creatinine, total protein, and albumin level of the patients were 54.5+/-13.1mg/dL, 12.3+/-3.0mg/dL, 6.7+/-0.8g/dL, and 3.8+/-0.6g/dL, respectively. 4) There were no significant differences in age, sex ratio, CAPD duration, peritonitis rate, %LBM/ Bwt, and SGA among the 4 groups. 5) Total protein (g/dL) and albumin (g/dL) levels in high transporters were 6.4+/-0.5, 3.5+/-0.4, respectively, and they were significantly lower than those of low transporters (7.2+/-0.6, 4.2+/-0.5) (P<0.05). 6) 24 hour dialysate protein (g/day) and albumin (g/day) losses were significantly higher in high transporters (8.10+/-1.85, 4.19+/-1.23) compared to those of low transporters (5.07+/-1.85, 2.78+/-0.99) (P<0.05). 7) The level of IGF-1 (ng/mL) was significantly lower in high transporters (150.5+/-86.2) compared to that of low transporters (310.3+/-162.1) (P<0.05). 8) The level of BUN (mg/dL), Cr (mg/dL) were also lower in high transporters (45.4+/-13.1, 10.1+/-2.0) than those of low transporters (61.6+/-18, 14.7+/-2.7), but there were no significant differences in Hct, total cholesterol, prealbumin, and transferrin among the 4 groups. 9) There were no statistically significant differences in Kt/Vurea, RRF, NPCR, dietary calorie and protein intakes among the 4 groups. 10) Anthrometric parameters such as TSF, BSF, MAC and LBM measured by three different methods (LBMCr, LBMimp, LBManthro) didn't show any significant differences among the 4 groups. In conclusion, increased peritoneal permeability may not adversely affect SGA and anthropometric status of long-term CAPD patients, although it is associated with lower serum albumin, creatinine, and IGF-1 level. Clinical significance of these findings remains to be elucidated.

This study investigated the trends of gastric cancer in Korea by adding the latest updated gastric cancer data from 2019. Gastric cancer incidence between 1999 and 2019 was reviewed using data from the Korea Central Cancer Registry. The study period was divided into 3 periods: period I (1999–2005), period II (2006–2012), and period III (2013–2019). The incidence, mortality, tumor location, histology, stage, and treatment were analyzed.Between 1999 and 2019, 577,502 patients were newly diagnosed with gastric cancer in Korea, accounting for 33.2% of patients aged ≥70 years. The age-standardized incidence rate (per 100,000) significantly decreased from 2011 (43.0) to 2019 (29.6), with an annual percent change of −4.50. Additionally, the age-standardized mortality rate (per 100,000) markedly decreased from 1999 (23.9) to 2019 (6.7). The proportions of patients with cardia and fundus cancers remained consistent. The proportion of localized stage cases increased, while those of regional and distant stages decreased. The rate of surgical treatment increased in localized and regional stages from 2006 to 2019. The overall 5-year relative survival (5YRS) rate of gastric cancer (per 100,000) increased from 55.7% in period I to 77.0% in period III. From 2013 to 2019, the 5YRS rates of patients (per 100,000) who underwent surgical treatment were 100.6% and 70.5% in the localized and regional stages, respectively. The results of this study demonstrated several changes in the epidemiology of gastric cancer in Korea. This study provides information to help understand the current trends in gastric cancer in Korea.

BACKGROUND AND OBJECT: Immunostimulatory CpG-oligodeoxynucleotides (ISS CpG-ODN) up-regulate the TH1-type immune response and down-regulate the TH2-type response. This study was performed to investigate the immune response changes resulting from ISS CpG-ODN on bronchial hyperrestponsiveness, eosinophilic inflammation and mucus hypersecretion in rat asthma. MATERIALS AND METHODS: 10 normal controls(NC) and 26 asthmatic rats, which were generated by ovallbumin(OVA) sensitization and challenge, were studied. The asthmatic rats were randomized into 11 asthma controls(AC) and 15 in the asthma-CpG treatment group(CpG). The CpG group was administered ISS CpG-ODN intramuscularly and the AC group was administered a placebo(0.9% NaCl)on day 15 and 20. After CpG-ODN or placebo administration, we measured the IFN-(TH1-type cytokine) and IL-4(TH2-type cytokine) levels in the bronchoalveolar lavage fluid(BALF), the specific airway resistance(sRaw), eosinophilic fraction in BALF, eosinophilic infiltration, goblet cell dysplasia and MUC5AC gene expression in the lung tissue. RESULTS: In the BALF of the CpG group, the IFN-γ concentration was significantly high and the IL-4 concentration was significantly low when compared with the AC group. Both the sRaw and eosinophilic fraction, and infiltration into the BALF and lung tissue significantly lower in the CpG group when compared with the AC group. However, little difference in goblet cell dysplasia and MUC5Ac gene expression was observed between the CpG group and the Ac group. CONCLUSION: ISS CpG-ODN decreases bronchial hyperresponsiveness and eosinophilic inflammation in the rat asthma model through the up-regulation of the TH1-type immune response with the down-regulation of the TH2-type response. However, the effect of these immune response changes on mucus hypersecretion was is not remarkable in this study.

OBJECTIVE: This study was carried out to evaluate the clinicopathologic significance of hepatocyte growth factor (HGF) and c-met expression as well as tumor angiogenesis in endometrial hyperplasia and adenocarcinoma. METHOD: By means of immunohistochemical staining, HGF, c-met expression, and angiogenesis were investigated in total of 49 patients (19 endometrial hyperplasia, 30 endometrial adenocarcinoma). HGF and c-met were identified with specific corresponding antibodies. To evaluate angiogenesis, the microvessels were highlighted by staining their endothelial cells immunohistochemically for anti-CD31. Areas close to the deepest myometrial invasion or those with the highest grade of endometrial hyperplasia and the highest angiogenic intensity were selected. Three fields of 400 magnification were selected for each slide, and the mean microvessel count was obtained. RESULTS: Diffuse staining for HGF was demonstrated in normal, endometrial hyperplasia and endometrial adenocarcinoma tissue in 45.5, 52.6 and 63.3 percent, respectively, while that for c-met was demonstrated in 9.1, 36.8 and 60.0 percent, respectively. c-Met overexpression was significantly correlated with high surgical stage as well as poor cellular differentiation. There were significant differences in microvessel count among normal, complex endometrial hyperplasia and adenocarcinoma (median 5, 9 vs. 22) and was between simple and complex endometrial hyperplasia (median 6 vs. 9). The microvessel counts were also significantly correlated with high surgical stage, poor cellular differentiation, lymph node involvement and deep myometrial invasion. CONCLUSION: This results suggested that both c-met overexpression and angiogenesis measured by microvessel count could be significantly important prognostic indicators for the prognosis of endometrial adenocarcinoma.

PURPOSE: The aim of this study was to identify the clinical features and natural history of dietary protein induced proctocolitis (DPIPC) and to detect the causative foods of DPIPC, and to evaluate the effect of elimination of the foods on the course of the disease. METHODS: Between March 2003 and July 2004, data from 30 consecutive patients with DPIPC who were followed for over 6 months, was reviewed. The diagnostic criterion used for DPIPC was an increase in the number of eosinophils in the lamina propria (> or =60 per 10 high-power fields). In breast feeding mothers, 5 highly allergenic foods were eliminated from the maternal diet for 7 days, namely, allergenic food groups such as dairy products, eggs, nuts and soybean, fish and shellfish, and wheat and buckwheat. We observed the disappearance or appearance of hematochezia after elimination or challenge with the offending foods. RESULTS: Before diagnosis infants were breast-fed (93.3%) or formula-fed (6.7%). Mean age at symptom onset was 11.5+/-5.1 (5~24) weeks, and mean age at diagnosis was 17.8+/-9.5 (8~56) weeks. Duration from symptom onset to diagnosis was 6.3+/-6.7 (0~36) weeks. Mean peripheral blood eosinophil count was 478+/-320 (40~1,790)/mm3 and eosinophilia (>250/mm3) was observedin 90.0% of patients. None of patients were found to have an increased serum IgE level. Of 15 patients that received sigmoidoscopy, nodular hyperplasia with erosion was observed in 93.3%. Of 27 patients whose mother ate the diet eliminated the 5 food groups, hematochezia diappeared in 74.1% of patients. Offending foods were identified as dairy products (37.5%), wheat and buckwheat (27.5%), fish and shellfish (20.0%), nuts and soybean (7.5%) and eggs (7.5%). A free maternal diet without patient's clinical symptoms was achieved at 29.4+/-8.7 (9~44) weeks of patient's age, and a free baby diet without blood in stools was achieved at 37.5+/-9.7 (12~56) weeks of age. CONCLUSION: DPIPC commonly occurs in exclusively breast-fed babies. Elimination of the above-mentioned 5 hyper-allergenic food groups from the maternal diet for 7days enables the detection of the offending foods. DPIPC is a transient disorder and 96.0% of patients can tolerate the offending foods at 12 months of age.

BACKGROUND: Oxytocin may cause adverse cardiovascular effects, including tachycardia and hypotension, whereas the optimal dose of oxytocin at elective cesarean section is unclear. To determine the lowest effective dose of oxytocin, we studied the hemodynamic effects of three doses during spinal anesthesia for elective single cesarean delivery. METHODS: Sixty women received oxytocin by continuous (0.5 IU/min) or bolus-continuous (2 or 5 IU prior to 0.25 IU/min continuous intravenous injection) intravenous injection after clamping of the umbilical cord. We compared changes in heart rate (HR), mean arterial pressure (MAP) and estimated blood loss (EBL). Uterine tone (UT) was assessed by palpation on a linear analog scale (LAS) at 5, 10, 15, 20 and 25 minutes after the oxytocin injection. In addition, oxytocin-related side-effects such as nausea and vomiting were recorded. RESULTS: Marked hemodynamic changes such as HR and MAP occurred in the bolus-continuous groups but not in the continuous groups. Although we were not able to observe a variation of EBL in each group, the UT significantly increased in the bolus-continuous groups when compared with that the continuous groups. In addition, the hemodynamic changes such as HR and MAP were lower in the two IU bolus-continuous group than those in the five IU group. CONCLUSIONS: Although bolus-continuous injection of oxytocin resulted in more hemodynamic changes than continuous injection, bolus-continuous injection had a greater effect on uterine contraction. Furthermore, two IU bolus-continuous injection showed lower hemodynamic changes than in the five IU bolus-continuous injection.
