1.Multiple Chorioangiomas of Placenta: A case report associated with repeated abortions and intrauterine fetal death.
Korean Journal of Pathology 1985;19(1):131-135
Chorioangioma is the most common primary tumor of the placenta. It is widely accepted to be formed from hamartomatous proliferation of angioblastic cells in early placenta. According to groups who systematically examined the placentas with the greatest scrutiny, the incidence of chorioangioma is 1~1.2% of all placentas examined. The clinical implication of chorioangioma has been emphasized due to its high association with hydramnios, antepartum and postpartum hemorrhage, premature onset of labor, or intrauterine fetal distress or death. The authors experienced a case of a 38-year old multigravida who had undergone 4 consecutive spontaneous abortions. The fifth pregnancy was carried to 35 weeks whereupon a dead fetus was delivered. The placenta was enlarged(950 gm) with multiple protruding nodules into the fetal surface. Microscopically, the nodule was composed of many vilous structures lined by chorionic epithelium. Within these structures was proliferation of endothelial lined capillaries some of which demonstrated ectatic change.

Development of supervoltage treatment machine may minimize skin reaction by skin-sparing effect, but skin damage is still one of “the dose limiting factor” in radiation therapy. In spite of these importance, systemic histopathologic studies of skin in similar conditions which used in clinical treatment has not been performed so far. 60 mice were irradiated with conventional fraction (200x5/wk) and whole abdominal field (2x3 cm, from symphysis pubis to xyphoid process). Used machine was 250 KV, 24 mA. orthovoltage x-ray machine. Histopathological changes of acute skin reaction at the level of total irradiation dose were analyzed and possible mechanism of later chronic changes were investigated. Obtained results are as follows 1. In 1,000 rad irradiated group, only mild epidermal edema is noted. 2. In 2,000 rad irradiated group, slightly decreased number and size of hair follicles and appendages, dermal edema and scanty infiltration of inflammatory cells are visible. 3. In 3,000 rad irradiated group, marked increased capillary congestion and prominent infiltration of inflammatory cells are observed. 4. In 4,000 rad irradiated group, vascular wall thickening with proliferation of endothelial cells are prominent. Dermal thinning and hyalinization are newly developed. 5. In 5,000 rad irradiated group, complete desquamation of epidermis is not seen, despite of acceleration of all above mentioned changes.

This study was due to investigate the dietary intakes, serum lipids and other hematological indices in female adolescent smokers. The subjects were 85 smokers, whose average pack-year(smoking years on the basis of one pack of cigarettes per day) was 1.26 and 87 nonsmokers who were female high school students in Seoul. An anthropometric measreument was performed and % body fat was also analyzed by the Bioelectrical Impedance Fatness Analyzer(GIF-891). Dietary intakes and food habits were examined through questionnaires and nutrient intakes were analyzed by the Computer Aided. Nutritional analysis program for professional(CAN-pro). Serum TG, HDL-cholesterol and total-cholesterol levels were measured with test kits. Serum glucose, albumin, GOT and GPT were measured by automated dry chemistry system, SPOTCHEM 4410. Hemoglobin, hematocrit, RBC, WBC and MCV were determined by Semi Automated Microcell Counter(F-520). All data were statistically analyzed by SAS PC package program. There was no significant difference in the anthropometric measurements between smokers and nonsmokers. The caloric intake in adolescent smokers tended to be higher than that of nonsmokers but the difference was not statistically significant. In addition, there was no significant difference between smokers and nonsmokers in biochemical indices. Analysis of serum lipids showed that the serum levels of total-cholesterol and LDL-cholesterol of nonsmokers were unexpectedly significantly higher(p<0.05) than those of smokers. Overall results indicate that smoking itself with short pack-year in healthy female adolescent did not seem to influence apparent health and nutritional status.

PURPOSE: The aim of the present study was to investigate the effect of single dose imipramine on nocturnal urine output in patients with nocturnal enuresis. METHODS:A total of 6 monosymptomatic enuretic patients of more than 5 years of age were enrolled in this study. We measured nocturnal urine output, urine osrnolality, creatinine clearance, osmolal clearance, excretion rate of solutes, fractional excretion of sodium and potassium, and plasma vasopressin with and without a single oral dose of imipramine(lmg/kg of body weight) at 8 p.m. RESULTS: The administration of imipramine was followed by a significant decrease in noctumal urine output(P=0.02). Urine osmolality was not significantly increased(P>0.05), but osmolal clearance was significantly decreased during imipramine medication(P=0.03). Urinary excretion rate of sodium and potassium showed a statistically insignificant trend toward lower values during imipramine administration in nocturnal enuretics. Fractional urinary excretion of sodium and potassium was significantly decreased during imipramine medication(P<0.05). There was no significant difference in plasma vasopressin level and creatinine clearance in nocturnal enuretics after imipramine. CONCLUSION: Imipramine has a vasopressin independent antidiuretic effect in patients with nocturnal enuresis. The antidiuretic effect of imipramine can be attributed prirnarily to increased a-adrenergic stimulation in the proximal tubules with secondary increased urea and water reabsorption more distally in the nephron.

Carcinoma of the uterine cervix is the most common malignant tumor in Korean women. It is well known that carcinogenesis is a multi-step event involoving the inactivation of tumor supressor genes, such as p53 gene and RB gene. The inactivation of the normal functions of the tumor-suppressor proteins pRB and p53 are important steps in human cervical carcinogenesis, either by mutation or from complex formation with the HPV E6 and E7 oncoproteins. The pRB protein regulates early cell cyle progression by controlling transit through the G1 phase of the cell cyle. The p53 tumor suppressor gene product also plays a role in cell cycle control by the transcriptional regulation of cyclin-CDK inhibitor. Cervical carcinoma is an excellent model for studying the stepwise progression of cell transformation because this is reflected morphologically by the increasing dysplasia of the squamous cells before it becomes and invasive squamous cell carcinoma. The aim of this study was to examine the expression of pRB and compared that with overexpression of p53 in a series of cervical lesions including normal tissuess, dysplasias, carcinoma in situ and carcinomas by immunohistochemical staining with monoclonal antibody to elucidate the role of these tumor suppressor genes. The result were as follows: 1. In normal cervical mucosa and CIN I , a few positively stained cells for pRB were seen in basal and parabasal layer. 2. An abnormality of pRB, loss of expression was seen in 23.8% of CIN III and in 10.8% of invasive carcinoma. 3. Overexpression of p53 was demonstrated in 14.3% of CIN III and in 59.5% of invasive carcinoma. 4. The immunoreactivity of p53 was significantly increased (p<0.05) in stage II, III than stage I , whereas downregulation of pRB and tumor stage was not correlated. 5. The immunoreactivity of p53 was significantly increased (p<0.05) in squamous cell carcinoma than in adenocarcinoma, adenosquamous carcinoma and CIN III. These result suggest that an alteration of pRB is more frequently implicated in CIN III than invasive carcinoma, whereas overexpression of p53 may be involevd in late progression of uterine cervical carcinoma.

BACKGROUND: Respiratory depression with high dose of propofol during induction is one of the major complications. We studied the effects of midazolam as premedicant on frequency and duration of apnea and frequency of loss of consciousness in relation to single dose of propofol. METHODS: We selected 194 adult patients who had clear consciousness and no depression of respiration. We allocated patients randomly to control group and midazolam group. In midazolam group, we injected 0.06mg/kg of midazolam intravenously 10min before induction, and in control group, we did nothing. Under mask oxygenation with 100% oxygen, we administered a bolus of propofol (1, 1.5, 2 mg/kg to subgroup 1, 2, 3 respectively) intravenously. The change of respiration and loss of consciousness were observed. RESULTS: The frequency and duration of apnea increased with the dose of propofol in both control and midazolam group. But there were no difference between groups except frequency of apnea with 1.5 mg/kg of propofol. In control group, frequency of loss of consciousness increased with the increasing dose of propofol. But in midazolam group, nearly all the patients was slept without difference by the dose. CONCLUSIONS: Premedication with midazolam reduce the sleeping dose of propofol to induce anesthesia, so the frequency and duration of apnea which is caused by high dose of propofol can be decreased.

BACKGROUND: The diagnosis of tuberculosis has been based on the detection of tubercle bacilli by acid-fast stain of smear or cultures, and recently the serologic diagnosis of tuberculosis has been provided a means of sensitive and specific detection of Mycobacterium tuberculosis. We evaluated the utility of enzyme immunoassay using determiner Tuberculosis Glicolipids(TBGL) antibody kit(Kyowa Medex Co. Ltd, Japan) to detect anti-TBGL antibody for diagnosis of pulmonary tuberculosis. METHODS: Anti-TBGL antibody assay was performed to the form 44 patients with active pulmonary tuberculosis(17 patients with smear positive, 7 patients with only culture positive, 20 patients with clinically active tuberculosis) and 80 controls (30 healthy controls, 24 patients with non-tuberculous respiratory diseases, 26 patients with inactive tuberculosis). We compared the sensitivity and specificity of anti-TBGL antibody with culture and AFB stain. RESULTS: Anti-TBGL antibodies were detected in 16 of 17(94%) smear positive patients, 4 of 7 patients with only culture positive and 16 of 20(80%) smear negative patients who had been clinically diagnosed as active pulmonary tuberculosis. Nine(35%) out of 26 patients with inactive tuberculosis, one(4%) out of 24 patients with non-tuberculous respiratory diseases and no one of healthy control had a positive antibody response. Overall sensitivity, specificity of the anti-TBGL antibody assay were 82%, 88%, respectively and sensitivities and specificities of culture and AFB smear 64%, 97%, and 49%, 100%, respectively. Anti-TBGL antibody titers in patients with active tuberculosis were significantly higher than control grup(P<0.05). Conclusions : The anti-TBGL antibody assay was sensitive, rapid and convenient. This assay will be useful as a tool for the diagnosis of tuberculosis in combination with other conventional methods.

10.What are the illnesses associated with frailty in community-dwelling older adults: the Korean Frailty and Aging Cohort Study
Sunyoung KIM ; Hee-Won JUNG ; Chang Won WON
The Korean Journal of Internal Medicine 2020;35(4):1004-1013
Background/Aims:
Frailty is mainly due to an age-related decrease in the physiological reserves needed to maintain biological homeostasis, but it can also occur as a result of chronic diseases. The purpose of this study was to identify illnesses associated with frailty in Korean community-dwelling older adults.
Methods:
This was a cross-sectional study that included 2,936 older adults aged between 70 and 84 years who had completed both interviews and physical function assessments for the Korean Frailty and Aging Cohort Study. Current illnesses diagnosed by physicians were included in the analysis. The definition of frailty was derived from the Fried frailty phenotype.
Results:
The prevalence of hypertension, diabetes mellitus (DM), arthritis, osteoporosis, urinary incontinence, and lung disease (including asthma, chronic obstructive pulmonary disease, and chronic bronchitis) was higher in the frail group (p < 0.05). After adjusting for age, sex, physical activity, alcohol, smoking, education, and presence of a spouse, the odds ratios for DM and urinary incontinence in frailty were 1.51 (95% confidence interval [CI], 1.10 to 2.01; p = 0.01) and 1.88 (95% CI, 1.11 to 3.18; p = 0.02).
Conclusions
In Korean community-dwelling older adults, DM and urinary incontinence were associated with frailty after adjusting for various factors. In the future, the list of comorbid diseases that are appropriate for Korean population- specific frailty assessment should be inventoried.
