BACKGROUND: In retrospective studies relating body weight to disease, the source of information on the Past body weight and height is often based on recall. Several studies examined the accuracy of recalled body weight and height, and factors that might affect the accuracy of recall but data on the accuracy of the recalled weight and height are scare. This study examined the eccuracy of recalled body weight and height, over a 5year period. METHODS: Participants was two hundred and two men and women visiting Health Promotion Center of medical colleage hospital, from 1th Jan. to 30th Jun.1996. We compared of measured weight and height with recalled weight and height 6year later and examined of the influence of sex, occupation, education, chronic disease on recall. RESULTS: When we defined recall error as measured body weight and height minus recalled body weight and height, the mean of weight errors were 0.02 +/-3.22 kg, and the measured body weight was significantly correlated with recalled body weight (r = 0.96). The mean of height errors were -0.80 1.95 cm, the correlation was 0.97. Weight errors were negatively correlated to weight gain over 5year period (r= -0.49). The accuracy of recall was not influenced by sex, education, occupation, chronic disease. CONCLUSION: Middle aged men and women recalled their previous 6year weight and height well in this study. The recalled past body weight and height are feasible information in retrospective study relating body weight to disease.

Journal of Korean Academy of Oral Health 2021;45(3):111-118
Objectives:
This study aimed to examine oral health literacy (OHL) in mothers and the factors that influence it.
Methods:
A total of 431 mothers of preschool children were chosen as study participants using the convenience sampling method. A self-administered questionnaire was used in this study. The survey contents included the socioeconomic characteristics of the participants as well as their level of oral health literacy.
Results:
In total, 44.8 percent of the participants had a low level of verbal oral health literacy (0-6 grade), and 16.9 percent had a low functional oral health literacy (≤6). Educational level and family income were significantly associated with the participants’ oral health literacy (Pearson correlation). Verbal oral health literacy of the participants was related to their family’s income, whereas their functional oral health literacy was related to their educational level.
Conclusions
Many of the participants had a low level of oral health literacy. For mothers, to improve their oral health literacy, an oral health literacy program must be in place. Oral health literacy programs should be targeted toward mothers with low socioeconomic status.

Purpose:
Given the long history of investigation into cancer and its relevance to the lymph node (LN), it would be meaningful to plot the trends of research on cancer-related LN.
Methods:
Queries such as “cancer,” “lymph node,” and “cancer and lymph node” were submitted to PubMed to collect articles on cancer and LN published between 1945 and 2017. The collected articles were then extracted by an automatic web crawler and examined through informetrics and linguistic analysis.
Results:
The number of articles related to cancer was 2,795,476 and 127,897 articles (4.6%) were found to be relevant to LN. With regard to cancer types, breast cancer was the most studied (37%), followed by gastric cancer (17%). With regard to the subjects in which the surgeon is interested, LN metastasis (57%) was found to be the topic most discussed, followed by LN dissection (22%) and sentinel LN (17%). Publications on LN metastasis gradually increased over time from 1988 to 2017 although those on sentinel LN and LN dissection have stagnated since the early 2000s.
Conclusion
Although research on cancer was abundant, only a small portion was dedicated to investigating its relevance to LN. Western countries had led the research on cancer-related LN, but Asian countries began to participate as major players, expanding their contributions. While LN metastasis, one of the major cancer-related LN topics, showed a steady increase, those involved in oncologic surgery such as LN dissection and sentinel LN did not.

Despite the increasing use of alternative analgesic agents, salicylate overdose remains a not-uncommon problem. Severe poisoning is life threatening, so prompt treatment and supportive measures are required to reduce mortality. Generally, salicylate intoxication results in the development of high-anion-gap metabolic acidosis. However, outside of Korea, normal-anion-gap or negative-anion-gap metabolic acidosis with hyperchloremia is rarely reported. We report herein the case of an 83-year-old female patient with chronic aspirin intake who presented with hyperchloremia and a negative anion gap. The patient's symptoms improved with conservative treatment and hemodialysis; notably, her chloride levels decreased as her blood salicylate concentrations decreased. Salicylate may cause hyperchloremia, demonstrating the importance of careful documentation of patient medication histories.

OBJECTIVES: The purpose of this study was to compare the value and utility of certain oral health indicators in adults. METHODS: The data used for analysis was obtained from the 6(th) Korean National Health and Nutrition Examination Survey (2013-2014). The study subjects were 7,729 adults aged between 20 and 64 years. The oral health indicators used for the analysis were T-Health (tissue health index), FS-T (functioning teeth index), and DHC of 1st molar (dental health capacity of the first molars). Descriptive statistical indices for oral health indicators were obtained (mean, skewness and kurtosis, and coefficient of variation). The correlation among oral health indicators, DMF, and sound tooth structure was analyzed. RESULTS: The oral health indicator scores had an abnormal distribution. DHC of 1st molar is found to be the most reliable indicator because it most accurately reflects the oral health decline that occurs as a result of aging. In all ages, DHC of 1st molar marked the lowest value in skewness and kurtosis. However, the skewness and kurtosis values of T-Health in adults younger than 44 years old were found to be the lowest among all age groups. FS-T is believed to most accurately reflect oral health status as it has a high correlation with sound tooth structure and sound tooth surfaces. T-Health is evaluated to most accurately reflect oral disease indicators as it appears to have a high correlation with DMF and high caries risk. CONCLUSIONS: The oral health indicators T-Health, DHC of 1st molar, and FS-T have distinct characteristics that can serve as different health indices. Therefore, they can each be utilized in various fields of oral epidemiology.

OBJECTIVES: To identify dentists' perceptions regarding the possible introduction of private health insurance plans, thereby providing basic data to improve the existing dental health insurance system. METHODS: A self-report survey was conducted with a total of 126 dentists in Jeollabuk-do Province. The survey was designed to gather information on the dentists' positions, perceptions and attitudes toward on a proposed introduction of privately run insurance schemes. RESULTS: A negative general consensus was found for the privately run scheme. Also it appeared that an overall review was required. CONCLUSIONS: Considering the high percentage of negative responses in the present study, it seems necessary to pro-actively reflect and complement potential issues in the current system before implementing privately run schemes in efforts to establish a solid foundation for operating dental insurance plans best suitable to the needs and characteristics of premium payers.

OBJECTIVES: The purpose of this study was to examine verbal oral health literacy and its influencing factors among adults. METHODS: The subjects in this study included 760 adults who were selected by convenience sampling from the residents in the cities of Iksan and Jeonju. The data were collected from a self-reported questionnaire survey and interview. RESULTS: As a result of testing the verbal oral health literacy of adults, 63.7 percent of subjects were deemed to be at a seventh or eighth grade level and 29.1 percent were at a fourth to sixth grade level according to the REALM. The dental term that was the most elusive for the adults was 'eruption', followed by 'apicoectomy', 'cavity', 'inlay' and 'fistula'. Verbal oral health literacy was related to education level, gender, and family income. CONCLUSIONS: The level of oral health literacy was low in many adults. Therefore, easy language should be used as much as possible when oral health education materials are prepared. Furthermore, the development of effective oral health education programs is urgently required in order to improve the oral health literacy of adults.
