PURPOSE: To evaluate ultrasonographic findings and usefulness in the diagnosis of breast diseases during pregnancy and lactati ng period. METHODS AND MATERIALS: The authors evaluated the ultrasonographic findings of 18 breast diseases during pregnancy and lactation retrospectively. The ultrasonographic examinations were performed with linear-array 5 MHz transducer (ATL). Final diagnoses were obtained by the excisional biopsy, fine needle aspiration and clinical follow-up. RESULTS: Total 18 cases of breast diseases were consisted of 8 cases of galactocele, 4 cases of fibroadenoma, 3 cases of axillary accessory breast, 2 cases of lactating adenoma, and I case of phylloides tumor. The ultrasonographic findings of the above breast diseases were valuable in the diagnosis and therapeutic planning. CONCLUSION: Ultrasonography is the initial and useful method of diagnosing breast diseases during pregnancy and lactating period.

BACKGROUND: Toluene diisocyanate (TDI) is the most prevalent agent to cause occupational asthma (OA) in Korea. The pathogenic mechanism of TDI-induced OA is still unclear. Involvement of both immunological and non-immunologicaI mechanisms have been suggested. OBJECTIVE: To evaluate a possible role of neutrophil in the development of TDI-asthma. OBJECT AND METHOD: Myeloperoxidase (MPO) as a neutrophil activation marker in both serum and induced sputum, and IL-8 in induced sputum were measured. Induced sputa and sera were collected from 15 TDI-induced OA patients (classified to group I) during TDI- bronchoprovocation test and were compared with those from 11 asthmatic subjects with negative TDI-bronchoprovocation test (group II). MPO levels were measured by radioimmunoassay, IL-8 levels, by enzyme linked immunosorbent assay and albumin levels, by nephelometry. Sputum MPO and IL-8 levels were presented as a ratio to albumin. RESULT: Serum MPO level tended to decrease during the TDI-bronchoprovocation test in two groups, but no statistical significance was reached (p>0.05). However, the ratios of MPO (the ratio of MPO level measured at 30 min to MPO level at baseline, and the ratio MPO level measured at 360 min to MPO baseline) in group I were significantly lower than group II (p=0.004, p=0.03 respectively). The IL-8/albumin and MPO/albumin levels in induced sputum from group I were significantly increased after the TDI-bronchprovocation test in comparison to the baseline value which was obtained before the bronchoprovocation test (p=0.0l, p=0.02 respectively). There was a significant correlation between the percent increase of IL-8/albumin and the MPO/albumin in induced sputum (r=0.89, p<0.05). CONCLUSION: These findings suggest a possible involvement of neutrophil in the development of bronchoconstiction after the TDI exposure, and IL-8 might contribute to neutrophil recruitment to airway mucosa. Further investigation will be needed to investigate mechanism of neutrophil activation in the pathogenesis af TDI-induced OA.

OBJECTIVE: Asymmetries in evoked potential P300 topography of schizophrenia and bipolar disorder are still controversial. The purpose of this study was to examine the difference in P300 topography between schizophrenia and bipolar disorder. METHOD: P300 was recorded from 16 schizophrenic, 15 bipolar manic, and 16 control subjects. All were right-handed. Subjects silently counted target stimuli(2.0kHz) among trains of standard stimuli(1.0 kHz). Averages were constructed from brain responses to target stimuli. RESULTS: 1) Schizophrenics displayed significantly smaller peak amplitude of P300 over Cz, Pz, T3 than controls. 2) Schizophrenics displayed significantly smaller peak amplitude of P300 over T3 than bipolar manics. 3) Schizophrenics displayed significantly smaller peak amplitude of P300 over T3 than their T4. 4) Schizophrenics displayed significantly delayed latency of P300 over T3 than bipolar manics. 5) Schizophrenics displayed significantly delayed latency of P300 over T3 than their T4. CONCLUSION: Left-sided P300 abnormality, especially left superior temporal gyrus, in schizophrenics, relative to bipolar manics and controls suggests that psychophysiological cause of schizophrenia and bipolar disorder is different and P300 asymmetry is specific to the psychophysiological cause of schizophrenia.

Primary pulmonary tuberculosis is one of the common pulmonary disease affecting children in Korea. Simple chest film is essential in diagnosis of primary pulmonary tuberculosis, but it is difficult to interpret the findings in some cases. Authors reviewed chest films of 162 cases of clinically confirmed primary pulmonary tuberculosis from April 1978 to June 1981 at Seoul National University Hospital. The results are as follows; 1. Lymph node enlargement, either hilar or mediastinal, was found in 82.7% and pulmonary parenchymal infiltration in74%. 2. Incidence of unilateral and bilateral hilar lymph node enlargement is about 50% (81cases) and 30% (49cases) respectively. Incidence of unilateral and bilateral mediastinal lymph node enlargement is about 21% (34cases) and 4.3% (7 cases), more common in right side. 3. Pulmonary parenchymal lesion is demonstrated in 74% (120cases). The pattern of primary focus is as follows in order; patchy infiltration 47% (76 cases) linear-streaky infiltration 15% (25 cases), lobar or segmental homogenous infiltration 9% (14 cases), nodular infiltration 4% (7cases). The primary focus of right lung is two times as common as that of left. 4. Calcification in primary focusis noted in about 27% in pulmonary parenchyma and 49% in hilum. 5. Plerual effusion is identified in 10%, but pleural effusion without pulmonary parenchymal lesion or lymph node enlargement is noted in only 2% (3 cases).

Double-outlet right ventricle is defined as follows: both great arteries arise completely or nearly completelyfrom the right ventricle; neither semilunar valve is in fibrous continuity with either atrioventricular valve; andusually a ventricular septal defect is present and the only outlet from the left ventricle. A total of 44 cases ofdouble-outlet right ventricle is analyzed, in which cineangiocardiographies were done at the Department ofRadiology, Seoul National University Hospital in recent 4 year and 6 months, with specific reference to thesegmental combinations, the height of conus the relationship of great arteries, the location of ventricular septaldefects, and associated anomalies. The resuslts were as follows; 1. Among 44 cases, 36 cases had normal cardiacposition, 4 cases had dextrocardia with situs inversus, 2 cases had dextrocardia with situs solitus, 1 case hadlevocardia with situs inversus, and another 1 case had mesocardia with situs ambiguus. 2. Segmental sets were[S.D.D] in 36 cases, [I.L.L] in 3 cases, [I.D.D] in 2 cases, [S.D.L], [S.L.L] and [A,D,D] in 1 case respectively.3. All cases had bilateral conus. Aortic valve rings were same level as pulmonary valve rings in 25 cases, lowerthan pulmonary valve rings in 17 cases in which 15 cases were type A., and higher than pulmonary valve rings in 2cases. 4. The relation of the great arteries were normal in 15 cases, side-by side in 13 cases, dextromalpositionin 13 cases, and levomal position in 3 cases. 5, The position of the ventricular septal defects with respect tothe origins of the great arteries is subaortic (type A & type B) in 23 cases, subpulmonary (type C) in 13 cases,double committed (type D) in 3 cases, and uncommitted (type E) in 5 cases. 6. Associated cardiac malformations arepulmonary stenosis in 24 which had all cases of type A and type E, aortic stenosis in 6 which were only in type C,left SVC in 6, abnormality of atrioventricular valve in 5, single coronary artery in 4, interrupted IVC in 1,obstructive VSD in 2, ASD in 4, PDA in 4, right aortic arch with levocardia in 5, and ectopic spleen withmesocardia in 1 case. 7. Biplane cinecardioangiogram must be performed in both ventricles to define the VSD andits relationship to the great arteries, and, if necessary, should also be performed in the aorta to rule outcoarctation and coronary artery abnormalities, and in the pulmonary artery to visiualize pulmonary venous returnand mitral valve. Angiography is of crucial importance in differentiating double-outlet right ventricle fromtetralogy of Fallot and complete transposition of the great arteries.

BACKGROUND: Hop Japanese (Hop J) pollens are abundant in the air of Korea during the autumn season. Their significances as a source of allergenic sensitization have been underestimated in this country. MATERIAL AND METHOD: In other to observe clinical features of Hop J-sensitive asthmatic patients in this country, skin prick test with Hop J pollen was performed. The serum specific IgE antibodies to Hop J pollen antigen were detected by enzyme linked immunosorbent assay (ELISA) in positive responders (>2+ of A/H ratio) on skin prick test. To confirm the respiratory sensitization, bronchoprovocation test was performed in 17 asthmatic patients sensitive to this pollen. RESULT: Ten asthmatic subjects showed a significant bronchoconstriction following the inhalation of Hop J pollen extract (6 early and 4 dual astmatic responses) and all of them had high serum specific IgE bindings, with minimal bindings in negative responders. They have suffered from seasonal aggravation of asthmatic symptoms with or without rhinitis, and/or conjunctivitis symptoms. The skin reactivity to Hop J had more than 5+ of A/H ratio on skin prick test in nine positive responders, whlie negative responders showed from 1+ to 3+ response. Moreover, four (40%) asthmatic subjects showed a positive response to only the Hop J pollen on skin prick test and an isolated positive asthmatic response to the Hop J bronchoprovocation test. CONCLUSION: We believe that the Hop J pollen should be considered as an allergen during the Autumn season, and thus included in skin test batteries in this area. Some labelled having intrinsic asthma or rhinitis might be sensitized to this pollen or other unknown allergens.

To evaluate the health risk of the workplace environment of a general hospital toward the hospital workers, a questionnaire survey on the perception of risk at the workplace environment and environmental measurements at 27 locations with 240 workers in the hospital were made from October 25th, 1993 to October 30th, 1994. The results were as follows; 1. By the environmental measurements, 86 workers(36%) were found to be exposed to poor or harmful degree of general illumination, 193 workers(80%) were exposed to poor or harmful local illumination, 34 workers(14%) were exposed to poor or harmful degree of thermal condition and l80 workers(75%) were exposed to poor or harmful noise level, but nobody was exposed to poor or harmful dust and toluene concentration. Also nobody was exposed to poor or harmful level of radiation or anticancer/antibiotic agents. 2. The subjective perceptions on the environmental conditions felt by the workers were different from the objective findings by the environmental measurements. The workers underscored the poor illumination state and overscored the dust concentrations. Also workers oversensitized about the thermal condition, the noise level, the radiation level, the toluene concentration and anticancer/antibiotic agents. 3. The sources of noise were the dialogue(179 workers) and the office instruments(131workers). The sources of dust came from the clothes(108 workers) and the building materials(79 workers). 4. The questionnaire survey showed that the 28 workers were exposed to poor or harmful level of the antibiotics, 10 workers to alkali or acid and 6 workers to drug dust in the pharmacy but the above findings could not be proved by the environmental measurements.

BACKGROUND: This study aimed to assess the status of infection control during influenza A pandemic (H1N1) 2009. METHODS: A questionnaire survey was conducted in November 2009 at the 100 hospitals designated by the Korea Centers for Disease Control and Prevention (KCDC) as influenza A pandemic (H1N1) 2009-treatment institutions. RESULTS: In 32.3% of the hospitals, the ventilation system of the influenza A pandemic (H1N1) 2009 isolation ward was separated from the hospital's ventilation system. With regard to wearing personal protective equipment while caring for patients with H1N1 infection, during usual patient contact, masks were always worn by all medical staff at all the hospitals; however, medical staff at 38.7% and 51.6% of the hospitals did not wear gloves and gowns, respectively. During aerosol-generating procedures, some medical staff wore surgical masks, whereas medical staff at 10% and 23.3% of the hospitals did not wear gowns and protective goggles, respectively. In all, 64.5% of the hospitals responded that the contents of the guidelines established by the KCDC were insufficient for reference purposes in actual practice. CONCLUSION: Some of influenza A pandemic (H1N1) 2009-treatment institutions are believed to be inadequate in facilities, infection control during patient treatment, and administrative measures among their efforts to prevent transmission in hospital. In preparation against the outbreak of similar diseases in the future, the government needs to establish guidelines highly applicable by medical staff, to secure exclusive spaces and personnel for treating infectious disease patients, and to develop personal protective gear support and management systems.
