The preventive effects of calcium gluconate injection and administration of anion feed on occurrence rates of the abomasal displacement and retained placenta were examined from 86 pregnant cows reared in Paju and Goyang cities in Gyunggi Province. The cows were divided into 3 groups: control (30 heads), experimental group I (28 heads) and experimental group II (28 heads), respectively. The control cows were not treated at all. The cows in experimental group I were intravenously injected with calcium gluconate(CMPK, Am. Tech. Canada, 10 g/head). The cows in experimental group II were given with the anion feed (Goyang TMR, Korea, 9 kg/head/day). The occurrence rates of the abomasal displacement in experimental groups were lower than that of control group and experimental group revealed the lowest prevalence rate, however, significance was not detected. The occurrence rate of retained placenta in experimental groups revealed lower prevalence than that of control group and experiment group II showed the lowest prevalence rate(p<0.01). Considering the above findings collectively, it was thought that administration of anion feeds was affective for prevention of the bovine retained placenta during drying milk period.

Wild owls are widespread in Korea, even being common in urban areas due to the presence of hills or small mountains in and around the cities. This results in high levels of contact between owls and domestic animals. This study investigated the prevalence of avian hematozoan parasite infection in 2 common owl species in Chungbuk province of Republic of Korea for 3-year period: the Eurasian eagle owl (Bubo bubo) and the Brown hawk owl (Ninox scutulata). Peripheral blood smears taken from 56 wild owls were examined by microscopic examination and confirmed by molecular technique. Twenty (36%) of these samples tested positive for the Haemoproteus infection. The infection rate was higher in Brown hawk owls (50%) than in Eurasian eagle owls (33%). These results indicate that the wild owls may act as a reservoir for Haemoproteus infection in susceptible domestic birds.

Purpose: This study was conducted to investigate the progression of Cobb's angle of middle school students according to the Risser grade changes during a one-year follow up period, and to identify the prevalence rate and related factors regarding scoliosis. Method: A total of 2,124 middle school students were preliminarily screened by the Adam's forward bending test. Among them, 21 adolescents diagnosed with scoliosis (above 5Cobb's angle) by X-Raying were the subjects and followed up for checking Cobb's angle and the Risser grade for one year. Results: The overall prevalence of scoliosis in middle school students was 2.13% and the prevalence in girls was higher than in boys. The Cobb's angle was significantly high in seniors and girls. The cases in low angle and low Risser grade demonstrated significant changes in progressive Cobb's angle compared to the cases in high angle and high Risser grade after one-year. But gender and pattern of curvature were not significantly different from the changes scoliosis angle after one-year. Conclusion: Based on these study results, juniors in low Risser grade were inclined to aggravate scoliosis despite the low degree of curvature at the first measurement.

Asthma and allergic diseases are one of the most common disorders in children. Due to its increased prevalence, as well as the increased morbidity and mortality from these diseases, asthma and allergic diseases have come to be recognized as a major worldwide public health issue. In addition, socioeconomic burden of asthma and allergic diseases has increased in Korea also. The International Study of Asthma and Allergies in Childhood (ISAAC) investigated the worldwide prevalence of asthma and other allergic diseases using simple standardized methods because of the comparison of asthma and allergic diseases between the countries. In Korea, several epidemiologic studies have been conducted to determine the prevalence of asthma in children. Although these studies showed increased prevalence of asthma among Korean children (from 3.4% in 1964 to 10.1% in 1989), these findings were based on data from small numbers of subjects. The first Nationwide Study of Asthma and Allergies in Korean Children, which utilized the Korean version of ISAAC written and video questionnaire, was conducted in 1995 and the second Nationwide Study of Asthma and Allergies in Korean Children was conducted in 2000, directed by the Korean Academy of Pediatric Allergy and Respiratory Diseases. We report here the prevalence of asthma and other allergic diseases in Korean children and adolescents, and show the changes that occurred over this 5 year period. We also describe the risk factors for development of these diseases in Korean children. We developed Korean versions of the ISAAC written (WQ) and video (AVQ) questionnaires for allergic diseases. In 1995, the enrolled population consisted of 25,117 children selected from 34 elementary school and 14,946 children selected from 34 middle school across the nation, the response rate was 94.8%. In 2000, 27,831 children selected from 34 elementary school and 15,214 children selected from 34 middle school, and the response rate was 96.4%. From these studies, we can confirm that increase of the prevalences of asthma, allergic rhinitis, and atopic dermatitis in Korea, except the prevalence of food allergy. Especially, the video questionnaire showed increases in the lifetime and 12 month prevalence rates of wheeze at rest, exercise-induced wheeze, nocturnal wheeze, nocturnal cough, and severe wheeze over this period of time in middle school children. In addition, the increase of prevalences of symptoms, diagnosis and treatment of atopic dermatitis was noted significantly. Risk factor analysis showed that body mass index (BMI), passive smoking and living with a dog or cat were associated with higher risk of wheeze. Also the occurrence of fever during infancy and the frequent use of antibiotics were associated with the risk of wheeze. In conclusion, during the 5 year period from 1995 to 2000, the prevalences of asthma, allergic rhinitis, and atopic dermatitis has increased in Korean children. BMI, passive smoking, living with a dog or cat, the fever episodes in infancy, and the frequent use of antibiotics in infancy are important risk factors to development of asthma and atopic dermatitis. In the near future, the birth cohort study will be needed to investigate the causes of this increase and the natural course of allergic diseases, then we develop the methods to control asthma and allergic diseases.

Purpose: This research was aimed to investigate the effect of postpartum breastfeeding support on breastfeeding rates. Methods: The participants of this study were 43 mothers who admitted to the delivery room of a university hospital which was selected as a Baby-Friendly Hospital Initiative (BFHI) in Daegu. Data collection period was from September 17, 2008 to September 20, 2009. Twenty three mothers were assigned to the experimental group and 20 mothers, to the control group. During hospitalization, breastfeeding education was given to the both groups. But postpartum breastfeeding support by nurse's phone call to the experimental group was provided once a week for 4 weeks postpartum. Data regarding breastfeeding rates at postpartum 1, 2, 3, 4 weeks and 3 months were collected by phone call. Results: The breastfeeding rate of the experimental group was significantly higher than that of the control group at postpartum week 2, 3, 4 and 3 months. Conclusion: Postpartum breastfeeding support may be a useful intervention to increase breastfeeding rate and the first month is the most important time to establish breastfeeding.

Purpose: To determine the prevalence of abnormal cervical cytology, as diagnosed using a liquid-based cytology technique, in pregnant women attending the Antenatal Care (ANC) clinic at Siriraj Hospital. Materials and Methods: This cross-sectional study included 655 first-visit pregnant women who attended ANC clinic at Siriraj Hospital during June to November 2015 study period. After receiving routine antenatal care, cervical cytology screening was performed with the Siriraj liquid-based cytology technique. All specimens were reviewed by a certified cytopathologist using Bethesda System 2001 criteria. Patients with abnormal PAP results characterized as epithelial cell abnormalities were referred to a gynecologic oncologist for further management according to ASCCP Guidelines 2012. Results: Mean age of participants was $28.9{\pm}6.2$ years. Prevalence of abnormal cervical cytology was 3.4% (95% CI: 2.0-4.7). Among this group, there were ASC-US, ASC-H, LSIL, HSIL for 12(1.8%), 2(0.3%), 7(1.1%) and 1(0.2%), respectively. In 633 specimens of the normal group, infection was identified in 158 specimens (24.1%) which were caused by Candida spp. and Trichomonas vaginalis. Regarding patient perception about the importance of cervical cancer screening, although most women perceived screening to be important, 54% of participants had never been screened for cervical cancer. Rate of loss to follow-up in the postpartum period was as high as 41.8%. Conclusions: Prevalence of abnormal cervical cytology in pregnant women attending the ANC clinic at Siriraj Hospital was 3.4%. Inclusion of cervical cancer screening as part of antenatal assessment can help to identify precancerous lesions or cervical cancers in patients who might otherwise not be screened, thereby facilitating early treatment and improved patient outcomes.

Background: A recent guideline by the American Cancer Society recommended that mammography (MMG) should be done for women starting in their mid-40s. In Thailand, information on opportunistic mammography screening is limited and data on the total incidence of breast cancer are also lacking. The purpose of this study was to estimate the breast cancer detection, incident and prevalence rates among Thai women. Materials and Methods: We retrospectively reviewed the opportunistic mammography screening of normal women between 30 and 80 years who underwent the procedure between 2001 and 2010. All cases were followed until 2012. The detection rate was calculated for the whole period of observation using 'number of women with positive findings' divided by 'total number of women screened'. The incidence rate was calculated only at the first MMG while the subsequence rate was calculated based on all new cases detected at each subsequent MMG. Results: Among the 47,430 women, there were 152,091 MMGs or approximately 3.2 occasions per person (range, 1-10). The average duration of the interval between each subsequence visit was 1.8 years. Overall, breast cancer was detected in 543 women, with a detection rate of 10.3 per 1,000 persons. The prevalence rate of breast cancer at the first visit was 5.78 per 1,000 persons. The incidence or new cases detected at any follow-up visit was 10.4 per 1,000 persons. The overall interval cancer was 0.91 per 1,000 women, mainly detected before their second and third MMG, with a rate of 0.0.47 and 0.76 per 1,000 women. Conclusions: Opportunistic mammography screening in Thailand detected 10 case of breast cancer from each 1,000 women. This paper indicated a high rate of cancer detection during a two year interval, hence, a screening mammogram should be performed more often.

The present study was conducted to investigate the prevalence of Eimeria infection according to anti-coccidiosis drugs treatment in 1,300 slaughtered chickens from 130 farms in Gyeongnam, Jeonnam, Jeonbuk, Gyeongbuk and Chungnam during the period from October 2002 to August 2003. The prevalence of Eimeria infection by drug administration for treatment and prevention or non-administration was shown $71.4\%,\;82.6\%\;and\;72.3\%$, respectively, and so infection rate of chicken farms was similar independent on drug administration or not. The prevalence of Oocysts infection level of chicken farms by administrated drug for treatment was shown lower $(25.3\%)$ than for prevention $(35.4\%)$ and non-treatment $(36.2\%)$. The prevalence of Oocysts infection level by drug administration under 2 days for treatment was shown higher infection rate $(32.2\%)$ than over 3 days $(20\%)$ and also under 2 days for prevention has similar tendency of that of treatment and so, it was conclusion that administration of drug over 3 days has the effect for treatment and prevention of Eimeria infection. The prevalence of Oocysts infection level by age for prevention has various level from $48.8\%\;to\;22.9\%$ but on $22\~25$ days was shown the most higher ratio $(48.8\%)$ and on $19\~21$ days was shown the lowest rate $(22.9\%)$ among the all age groups.
