Eyes as an exposed organ of human body are easily contaminated from environment including air and water and by bacteria on skin of hands and eyelids. Recently the contamination of environment is increasing and new generations of antibiotics are introduced and moreover their abuse is also serious, especially in Korea. All those factors seem to make the normal flora of conjunctiva change. It is true that psychosocial activity and environment change according to age. Therefore the authors investigated bacterial flora of the eye on 408 eyes of 408 Koreans without any inflammations. They were subdivided into eight groups by difference of psychosocial behaviour. In this study overall positive culture rate was 37.5% and total 168 isolates and 19 species were cultured. Major organisms were Staphylococcus epidermidis(42.8%), Staphylococcus aureus(19.0%) and Diphtheroid(14.8%). The rate of positive culture was 26.5% in the neonatal period, 53.3% in the infany, 42.7% in the preschool period, 48.5% in the late childhood, 32.7% in the adolescence, 27.1% in the adulthood, 43.6% in the middle age, and 41.9% in the old age. The highest rate of positive culture was 53.3% of the infancy and the lowest rate 26.5% of the neonatal period. It is interest that this study revealed the difference between male and female. The mean of positive culture rate was similar: 35.5% in male and 39.5% in fernale. The positive culture rate in female was much higher in the preschool period, the late childhood and the old age than in other periods; much lower in the adolescence and the adulthood. There was no significant difference in positive culture rate of each period in male, except the lowest rate in neonatal period and the highest rate in the infancy. The big difference of positive culture between male and female was shown in the late childhood and the adulthood. In the late childhood, female has much higher rate than male and much lower rate in the adulthood. As the result of this study, the authors concluded that normal flora of bacteria in conjunctiva was affected by psychosocial activity and environment according to age.

BACKGROUND: Despite modem diagnostic, staging, and therapeutic advances, esp. with molecular biologic techniques, the 5-year survival rate of all cases of lung cancer does not exceed 15%. Also, the incidence of lung cancer of both sex in Korea is increasing year by year and the lung cancer is one of the leading causes of cancer death. Therefore, it is strongly needed to develop the new combination of treatment modalities including neoadjuvant chemotherapy and to identify tumor specific characteristics with staging or prognostic markers. Here we present the clinical significance of several biologic tumor markers to use as a prognostic markers in patients with non-small cell lung cancers. METHOD: The survival has correlated with the expressibility of proliferative cell nuclear antigen (PCNA), epidermal growth factor receptor(EGFR), p53 and/or blood group antigen A(BGAA) using immunohistochemistry in 46 patients with non-small cell lung cancers. RESULTS: 1) The expression rates of PCNA, EGFR, p53 and BGAA were 80.6%, 61.3%, 45.9% and 64.3%, respectively and those were not correlated to cell types or clinical stges. 2) The expression of BGAA was correlated with better survival in median survival and in 2-year survival rate and that of PCNA was correlated with worse survival in median survival and 2-year survival rate. 3) The expression of EGFR or p53 was not valuable to predict prognosis in non-small cell lung cancers. 4) With simultaneous applications of PCNA, EGFR and p53 immunostain, the patients with 2 or more negative expressions showed better prognosis than the patients with 2 or more positive expressions. CONCLUSION: It is suggested that the expression of blood group antigen may be a positive prognostic factor and that of PCNA may be a negative prognostic factor. Also, the combination of expressions of PCNA, EGFR and p53 may be used as a negative prognostic factor.

A 22-year old female visited CNUH due to palpable neck mass. Cytologic examination of a fine needle aspiration was performed and the result was Pap class II. Routine chest x-ray shows solitary pulmonary nodule. For rule-out malignancy, FNA at neck mass was repeated and pathologic finding was dysplasia. She was admitted to MI department for evaluation of solitary pulmonary nodule and percutaneous needle aspiration was done. Pathologic diagnosis was adenoid cystic carcinoma. Thereafter, the lesions were treated by excisional biopsy of submandibular gland mass with left supraomohyoid neck dissection and wedge resection of right lower lobe at ENT department and thoracic and cardiovascular surgery department, respectively Final diagnosis was adenoid cystic carcinoma arising in submandibular gland with solitary lung metastasis. According to TMN staging system, surgical staging is stage IV of T2N0M1. Clinical follow-up to postoperative 13 months in this case showed that she is alive and well without evidence of recrrence.

Journal of Korean Medical Science 2023;38(35):e286-
Background:
We sought to identify the influence of prepregnancy glucose levels on obstetric complications in subsequent pregnancy.
Methods:
Women in Republic of Korea who had given birth between January 1st, 2007 and December 31st, 2010 were enrolled. The database of the Health Insurance Review and Assessment Service and data from a national health screening program for infants and children were used. Subjects were divided into seven groups according to their fasting glucose levels.
Results:
59,619 women were included for analysis, and 10.4%, 13.7%, 19.1%, 21.5%, 16.0%, 11.6%, and 7.5% women had glucose levels of < 75, 75–79, 80–84, 85–89, 90–94, 95–100 and > 100 mg/dL. Each 5 mg/dL increase in prepregnancy fasting glucose levels was associated with increased risk of gestational diabetes and macrosomia in subsequent pregnancy. Adjusted risk ratio for gestational diabetes per standard deviation prepregnancy glucose > 100 mg/dL was 2.015 (95% confidence interval, 1.649–2.462) and for macrosomia an adjusted risk ratio 1.389 (95% confidence interval, 1.147–1.682).
Conclusion
Higher prepregnancy glucose level within normal range was related to gestational diabetes and macrosomia in following pregnancy. Our results may aid in the identification of women at future risk of obstetric complications and may guide to stratify women into normal and intensified care.Tweetable abstractHigher prepregnancy glucose in normal range is associated with gestational diabetes and macrosomia.

Background:
Maladaptation to vascular, metabolic, and physiological changes during pregnancy can lead to fetal growth disorders. Moreover, adverse outcomes during pregnancy can further increase the risk of cardiovascular and metabolic diseases in mothers. Delivering a large-for-gestational-age (LGA) baby may indicate a pre-existing metabolic dysfunction, whereas delivering a small-for-gestational-age (SGA) baby may indicate a pre-existing vascular dysfunction. This study aims to assess the risk of hypertension (HTN) and diabetes mellitus (DM) in women with normal body mass index (BMI) scores who did not experience gestational DM or hypertensive disorders during pregnancy based on the offspring’s birthweight.
Methods:
This retrospective nationwide study included women with normal BMI scores who delivered a singleton baby after 37 weeks. Women with a history of DM or HTN before pregnancy and those with gestational DM or hypertensive disorders, were excluded from the study. We compared the risk of future maternal outcomes (HTN and DM) according to the offspring’s birthweight. Multivariate analyses were performed to estimate the hazard ratio (HR) for the future risk of HTN or DM.
Results:
A total of 64,037 women were included in the analysis. Of these, women who delivered very LGA babies (birthweight > 97th percentile) were at a higher risk of developing DM than those who delivered appropriate-for-gestational-age (AGA) babies (adjusted HR = 1.358 [1.068–1.727]), and women who delivered very SGA babies (birthweight < 3rd percentile) were at a higher risk of developing HTN than those who delivered AGA babies (adjusted HR = 1.431 [1.181–1.734]), even after adjusting for age, parity, gestational age at delivery, fetal sex, maternal BMI score, and a history of smoking.
Conclusion
These findings provide a novel support for the use of the offspring’s birthweight as a predictor of future maternal diseases such as HTN and DM.

BACKGROUND: Known as a kind of complication or a specific form of pulmonary tuberculosis, endobronchial tuberculosis caused several kinds of problems in diagnosis and managements. But the frequency of this disease are is widely variable, generally reported from as low as 10 - 20% to as high as 40 - 50%. We prospectively performed bronchoscopy in patients diagnosed as pulmonary tuberculosis to evaluate the frequency of endobronchial tuberculosis and its related findings. METHOD: From March, 1995 to February, 1996, we prospectively performed bronchoscopy in patients newly diagnosed as pulmonary tuberculosis and evaluated the frequency of endobronchial tuberculosis, its clinical features and laboratory findings including raiologic, microbiologic and physiologic aspects. RESULTS: Number of patients diagnosed as pulmonary tuberculosis was 103 and 55 patients(53.4%) were found to have endobronchial tuberculosis. But the frequency were 43.8% in male and 76.7% in female, respectively. Frequently noted symtoms were nonspecific including cough, sputum, fever, weight loss in the order of frequency but cough was more frequent than in pulmonary tuberculosis. Physical examination showed rale,decreased breathing sound and wheezing and wheezing was more frequent than in pulmonary tuberculosis. All 7 subtypes were noted bronchoscopically and edema-hyperemia (stenotic without fibrosis) type was most frequently(32.7%) noted, and followed by chronic nonspecific bronchitis type stenotic with fibrosis type and actively caseating type in the order of frequency. The relationship between subtypes of endobronchial tuberculosis and radiologic findings was insignificant. Right lung was involved more frequently than left lung and left upper lobe was most commonly involved site, and followed by right upper lobe and trachea. Acid-fast bacilli(AFB) positivity in sputum and / or bronchial washing fluid was 73% and suggested high risk of infectivity. CONCLUSION: The frequency of endobronchial tuberculosis in patients with pulmonary tuberculosis was higher than known and also suggested bronchoscopic examination to detect endobronchial involvement should be recommanded and careful management is also needed to prevent complications.

OBJECTIVES: To estimate the resistance rate and to correlate the clinical characteristics of resistant tuberculosis with the patients of pulmonary tuberculosis who were referred to the university hospital. METHODS: We prospectively performed sensitivity tests for all patients who were diagnosed as active tuberculosis by sputum smear or sputum culture from January, 1995 to June, 1996. Patients profile, previous treatment history, patterns of drug resistance, initial chest films and other clinical findings were analysed. RESULTS: Overall, 24(26.0%) of the 92 patients had resistance to at least one drug and 8(8.6%) had resistance to isoniazid(INH) and rifampin(RFP). Among the 66 patients without previous tuberculosis therapy, 11(16.6%) were drug-resistant and 2(3.0%) were multi-drug resistant. Among the 26 patients with previous therapy, 13(50.0%) were drug-resistant and 6(23.0%) were multi-drug resistant. For all 92, resistance to INH was most common (19.5%), followed by RFP (9.7%) and ethambutol (9.7%). Drug resistance was significantly high in previously treated patients and in cavity-positive patients. Treatment failure was also high in previously treated patients with resistant tuberculosis. In patients with primary resistance, treatment failure was not observed. CONCLUSION: Sensitivity tests are strongly recommended in all culture positive patients with previous therapy but, in patients with primary resistance, sensitivity tests are not required. Proper combination chemotherapy should be given under careful surveillance.
