Tracheobronchial aspergillosis is an unusual form of invasive aspergillosis characterized by noninvasive or only superficially invasive tracheobronchitis with a propensity for dissemination. We report a two-year-old male who suddenly died of respiratory failure. Postmortem examination revealed a pseudomembrane covering the mucosa of larynx, trachea and bronchial tree of both lungs. This pseudomembrane was composed predominantly of Aspergillus hyphae. There was transmural necrotizing bronchitis with fungal invasion to the narrow zone of peribronchial tissue, and dissemination to the stomach and kidney. This form of pulmonary aspergillosis had not been reported in this country.

3.Transmesenteric Hernia: An autopsy case.
Korean Journal of Legal Medicine 2000;24(2):57-60
Transmesenteric hernias through congenital mesenteric defects are the least common of intra-abdominal hernias and rare causes of acute intestinal obstruction in infants and children. Because of its rarity and difficulty of diagnosis, the mortality and morbidity were very high, and incarceration leads to intestinal obstruction and subsequently, strangulation and gangrene of varying lengths of intestine. We present an autopsy case of transmesenteric hernia through the defect of the mesentery of ileum, showing strangulationand obstruction of the affected small bowel.

Korean Circulation Journal 1993;23(1):117-122
BACKGROUND: Propafenone is effective in the treatment of ventricular arrhythmias and paroxysmal supraventricular tachycardia. Propafenone has been shown to be also useful in preventing the recurrence of atrial fibrillation. But to date, date concerning the efficacy of propafenone for patients experiencing paroxysmal and chronic atrial fibrillation have not been examined in Korea. METHODS: In patients with paroxysmal atrial fibrillation propafenone was given at a dose of 450mg daily without dose titration and symptomatic recurrences were evaluated by patient interview during follow-up. In patients with chronic atrial fibrillation, who had no previously attempted cardioversion, propafenone was given at a dose of 450~675mg daily without dose titration, and after a minimum of 3 days pharmacological cardioversion was assessed. Those patients in whom sinus rhythm had been restored pharmacologically or by combined direct current cardioversion were followed with maintaining propafenone therapy also at a dose of 450~675mg daily. RESULTS: Of 7 patients with paroxysmal atrial fibrillation, 4 (57%) patients had marked symptomatic improvement and they were followed for 197 to 460 (mean 286) days Of 13 patients with chronic atrial fibrillation, 7 patients incuding 4 pharmacologically converted patients were initially controlled to sinus rhythm. In 5 (38%) patients maintenance of sinus rhythm was followed for 90 to 415 (mean 224) days. CONCLUSION: Although these observations were made in small number of patients and are so limited, the results are comparable to the previous studies which showed the potential role of propafenone in the management of atrial fibrillation.

This study was undertaken to investigate the morphologic changes following flushing, preservation and reperfusion procedures in a canine lung allotransplantation model. Donor lungs were flushed with modified Euro-Collins (MEC) solution, low potassium dextran glucose (LPDG) solution or University of Wisconsin (UW) solution, then stored at 10oC for 20 hours. Light microscopic and electron microscopic features of the lungs were examined after flushing, preservation and 2 hours after reperfusion. After flushing light microscopy showed focal mild alveolar collapse and interstitial edema. After preservation the lung tissue showed multiple foci of alveolar collapse, consolidation, and alveolar epithelial cell damage. After reperfusion the lung tissue showed diffuse alveolar collapse, consolidation and many destroyed cellular debris in the alveolar lumina. After flushing electron microscopy showed focal alveolar collapse and mild swelling of type I epithelial cells. After preservation both type I epithelial cells and endothelial cells were swollen and destroyed focally. Some type I epithelial cells were detached from the basal lamina. The endothelial cells showed luminal protrusion of tactile-like structure and vacuoles of the cytoplasm. After reperfusion the lung tissue showed fibrin material in the alveoli, prominent type I epithelial cell swelling with fragmented cytoplasmic debris and marked endothelial cell swelling with vacuoles or tactile-like projections. The alveolar macrophages showed active phagocytosis. After preservation scanning electron microscopic examination of the pulmonary arteries showed multiple patchy areas of swelling or conglomerated lesions in the inner surface of the pulmonary arteries. In conclusion, the ultrastructural changes associated with flushing were mild in severity, the donor lungs were injured during the preservation, and further damage occurred during the reperfusion.

To assess the immunological function of toluene exposed group, the proportions of T lymphocyte, B lymphocyte, CD 4 cell, CD 8 cell, the ratio of CD4 to CD8 (CD4/CD8) in peripheral blood were measured on twenty-one toluene exposed workers and twelve healthy workers who did not have previous history of toluene exposure. In addition, to evaluate the present status of toluene exposure, urinary hippuric acid concenturations were measured in exposed group. The mean concenturation of urinary hippuric acid was 2.84 g/creatinine g in exposed group. The proportions of T lymphocyte, B lymphocyte, CD8 cell and CD4/CD8 of exposed group were slightly lower than non-exposed group except the proportion of CD4 cell which was similar in both groups. But these differences were not statistically different in both groups. The proportions of T lymphocyte and CD4 cell were significantly correlated with the length of duration in exposed group (P<0.05)

The authors studied the ultrastructural changes of liver cell mitochondria in autolysis. The male Sprague-Dawley rats, weighting 140~160 gm were sacrificed for extract liver tissue. The slices of the liver tissue were incubated in 37 degrees C aseptic normal saline, and those were examined by following intervals; 10, 20 and 30 minutes and 1, 2, 6, 12 and 24 hours with light and electron microscope. The results obtained by light microscopy were summerized as follow. Several fine intracytoplasmic vacuoles were observed 1 hour after incubation. After 3 hours, focal destruction of cytoplasmic membrane with pyknosis of nuclei were observed. More delicate intracytoplasmic architectural changes could not be detected at light microscopic studies. The cord arrangement and cellular boundaries were relatively well preserved until 24 hours after incubation. Electronmicroscopically, mild intramitochondrial swelling with diminution of intramatrical granules were observed at 20 minutes. These were the earliest findings. Both high amplitude swelling and destruction of mitochondrial membrane were observed concurrently at 1 hour after incubation. The earlier membrane changes were observed at inner membrane with cristae and followed by degeneration of the outer membrane. The intramatrical amorphous dense deposits were observed at 30 minutes when the membranes were not destroyed. These deposits were noted in the other experimental groups which were incubated longer than 30 minutes. More electron dense deposits were observed after 1 hour at that time the membrane changes appeared. Vhe results suggest in this experiment that the earliest autolytic changes of liver cell mitochondria is loss of intramitochondrial granules and the membraneous changes led to the irreversible mitochondiral injury. The appearance of two types of intramitochondrial dense deposits would be an interesting finding needed to require further investigation for the chemical stucture and mechanism of dense deposit formation.

Journal of the Korean Academy of Family Medicine 1997;18(4):377-384
BACKGROUND: Blood pressures rneasured by a nurse at reception room as a part of routine physical examination are oft,en used as a indicator of medical care. Blood pressure at reception room and consultation room are, however, often different to each other and these differences are caused by various factors including difference of white coat effect by nurse and doctor. Thus, this study was performed in order to know whether blood pressure difference really exit, and its associated factors. METHODS: Two hundred ninety one patients who visited to one university hospital farnily practice were enrolled in this study. Blood pressure and pulse rate at reception room and consultation room, waiting t,ime, time interval between reception and consultation, smoking status, and intake of coffee and food were collected. Nine patients were excluded, because blood pressure either at reception room or at consulation room was not recorded. This study was performed by one nurse and two doctors. They defined the guideline for method of blood pressure measurement before the study, and used the same kind of indirect cuff sphygmomanometer. RESULTS: Two hundred eighty two patients were analyzed. The number of men was one hundred twenty five. Systolic blood pressure at consultation room was higher than that at reception room by 1.6+/-11.9mmHg (P<0.05). Sixty five cases(65%) in systolic blood pressure and 111 cases(40%) in diastolic blood pressure showed blood pressure differences more than 5mmHg. The group with systolic blood pressure difference between reception room and consultation room(SBP) in more than 5mmHg is more likely to be hypertensive than the group with SBP in less than 5mmHg(P<0.01). More female patients(66%) and hypertensive patients(59%) were belong to the group whose systolic blood pressure at consultation room were 5mmHg higher than at reception room(P<0.01). Twenty four patients(30%) of the group whose systolic blood pressure at reception room were 5mmHg higher than at consultation room had cigarette smoking within 1 hour, and this ratio was significantly higher than the other groups whose systolic blood pressure difference was less than 5rnmHg or systolic blood pressure at consultation room were 5mmHg higher than at reception room(P<0.01). There was relatively good concordance in classifying hypertension and normal blood pressure according to measurement site(Overall kappa, 0.747, P<0.01). CONCLUSIONS: Many patients showed blood pressure differences more than 5mmHg between reception room and consultation room. Systolic blood pressure at consultation room was higher than that at reception room, and there was relatively good concordance in classifying hypertension and normal blood pressure according to measurement site, but the adverse effect by misclassification should not be neglected. The importance as well as the limitation of blood pressure measurement at reception room should be considered in screening and treating hypertensive patient. Every time when blood pressure is taken, physicians should keep in mind to consider patients factors which may influence blood pressure level.

There have been some controversies on prognostic significance of lymph node (LN) micrometastasis (MM) in advanced gastric carcinomas (AGCs). The present study aimed at 1) determination of prognostic significance of MM, 2) evaluation of the relationship between MM and clinicopathological parameters, and 3) determination of LN group where MMs were frequently found. We studied 70 cases of AGC without LN metastasis on initial examination. The tumors were examined for location, size, depth of invasion, differentiation, histologic type, lymphatic invasion, and c-erbB-2 expression. To evaluate MM, pancytokeratin immunohistochemistry was performed in all LNs from 70 cases of AGCs. Among 2,203 dissected LNs from 70 patients, 37 (1.6%) LNs from 19 (27.1%) patients revealed MM. Micrometastases were seen in only group 1 and 2 LNs: none had group 3 and 4 LN involvement. The gender, age, tumor size, location of tumor, histologic type, differentiation, depth of invasion, lymphatic invasion, and c-erbB-2 expression were not significantly associated with MM status. The survival time of the MM-positive group (mean: 62 months) was significantly shorter than that of the MM-negative group (mean: 72 months) (p=0.046). The findings of this study indicate that the presence of MM in LNs is an important prognostic factor in AGC patients.

Journal of the Korean Academy of Family Medicine 1997;18(6):577-590
BACKGROUND: Hypertension is one of the frequent problems for which family physicians are well encountered to manage. Nonpharmacologic measures which include stress relaxation, low salt diet, weight reduction, moderation of alcohol intake, physical activity, tobacco avoidance are used as definitive or adjuvant therapy for hypertension. Family physicians should vigorously encourage their patients to adopt these life style modifications. This study was conducted to know how many nonpharmacologic treat,ment modalities are adopted by hypertensives and to find predicting factors. METHODS: A total of 100 of the hypertensive patients who are followed up via the department of family medicine, Hanyang University Hospital, from September 1995 through November 1995 are included in this study. A trained nurse interviewed patients according to the previously designed structured questionnaire. The overall response rate was 90% and the fill-up rate of the questionnaire was 100%. RESULTS: Sixty three patients were women. The mean age was 57.4 years(range, 20 to 84). Sixty one percent accompanied one or more other diseases, of which diabetes mellitus was the most common disorder. The mean systolic pressure was 143.9 mmHg and the mean diastolic blood pressure was 89.3mmHg. Ninty-three percent of patients received antihypertensives with compliance of 81 to 100%. Twenty four percent of patients adhered to regular exercise, 36 percent weight reduction, 48 percent low salt diet, 79 percent moderate drinking, 81 percent stress relaxation, and 87 percent no smoking. Of those six non-pharmacological treatments, 3.6 behaviors were adhered. Male patients were more attended with the low salt diet. Eleven patients of 2S alcoholics(44.0%) reduced their amount of alcohol intake and 8 of 17 smokers quitted smoking (47.1%) after they were diagnosed as hypertension. The mean BEPSI score was 1.5. Fifty one percent of patients had stress within the last three months, 32 percent had cumulative fatigue. The occupational stress was the most common one. All exercise which patients reported were isotonic. Seventeen percent of the patients took certain herb medicine or folk medicine. CONCLUSIONS: Of those 100 hypertensives who were treated at the department of family medicine, Hanyang University hospital, 24% adhered to regular exercise, 36 per cent weight reduction, 48 percent low salt diet, 79 percent moderate drinking, 81 percent stress relaxation, and 87 percent quit smoking in order. Of those six non-pharmacological treatments, 3.6 behaviors were adhered on the average. Nonpharmacologic treatment should be promoted by family physician as an important strategy for treatment of hypertension.
