BACKGROUND: The purpose of study to present the basic data for enhancing the performance level of the dental clinic infection prevention through the actual condition of the implementation for dental treatment infection prevention aimed at dental hygienists in each hospital. METHODS: We carried out a survey targeting 69 dental hygienists in the dental college hospital, 42 in the dentist of the Dentistry in General Hospital, 51 in the dental clinic and 38 in the dentist's office and the medical institutions surveyed, and we used frequency analysis and chi-square analysis by using SPSS (Ver. 18.0). RESULTS: The experiences wounded in the body by sharp instruments or needles contaminated with patients' blood or saliva were on average in 86.5% of the dental hygienists, and people who disinfected the wound with disinfectants after washing their own hands and squeezing blood as the method to fight the wound was 73.4%. The dental clinic was the highest in case of the rate of wearing gloves, and the dental clinic was the highest in the case of the rate of wearing a mask. The use of the liquid soap containing antimicrobial was the highest as 28.0% in the dental college hospital in case of 'the cleanser to be used for washing their own hands'. In the multiple response for dental treatment mechanical equipment management apparatus and the actual condition to be equipped with medicines and the survey in sterilization, Povidone was the highest as 28% in the dental college, and surface disinfectants were being used in some hospitals. CONCLUSION: To prevent the infection in the consultation room, dental hygienists should thoroughly recognize Dental Treatment Infection Prevention Standards, and the research measures or administrative support of the government and the organs concerned is needed a lot.

BACKGROUND: EGF and TGF-a are ligands for the EGF-receptor and act as mitogens for a variety of tissues. TGF-a, in particular, has been implicated as an autocrine growth factor for several cancer cell lines. TGF-B exerts an inhibitory effect on the growth of most epithelial cell types, and the loss of responsiveness to this growth inhibition has been implicated in the development of a variety of human cancers. In the present study, we evaluate whether EGF, TGF-a and TGF-B modulate apoptosis and cell cycle progression in cervical cancer cell lines. MATERIALS & METHODS: The effect of EGF, TGF-a and TGF-B on apoptosis and cell cycle such as CaSki and HeLa cell lines was analysed by flow cytometry RESULTS: 1. TGF-B did not induce apoptosis in CaSki and HeLa cell lines. 2. TGF-B as well as EGF, TGF-a, did not affect the process of apoptosis significantly. 3. The time to occur apoptosis was different between CaSki and HeLa cells treated by growth factots. 4. G1 phase was the checkpoint in CaSki and HeLa cells treated with TGF-B. CONCLUSION: These results suggest that TGF-B as well as EGF, TGF-a does not induce apoptosis and cell growth inhibition.

Leiomyomas are the most common benign tumors of the uterus, and although they can occur at any site in the genitourinary tract, they very rarely originate from the urinary bladder. We report a case in which a leiomyoma occurred at that site, deseribing the US, CT, and MRI findings.

PURPOSE: This study was performed to evaluate the dietary nutrient intake status and hair mineral content of Korean young children. METHODS: Fifty-five children who visited Seoul National University Bundang Hospital were divided into three groups by age: infants, toddlers, and preschoolers. The 24-hour recall method was used to collect the food intake data of the subjects. Hair mineral analysis was conducted using a Mass Spectrometer. Serum iron, ferritin, and calcium were also measured. RESULTS: The mean energy intakes of the subjects were 730.3 kcal, 994.3 kcal, and 1,482.9 kcal for each age group. The mean percentage of energy intake compared to recommendation was 101.4% and was not different by age group. Toddlers of 37.8% and preschoolers of 54.5% consumed less than the Estimated Average Requirement (EAR) of calcium. Infants of 28.6%, toddlers of 10.8% and preschoolers of 9.1% consumed less than the EAR of iron. In the case of zinc, copper, and selenium, only 0% to 5% of toddlers and none of the preschoolers consumed less than the EAR of those minerals. The hair calcium, iron and copper concentrations were lower in toddlers and preschoolers than those in infants. Serum calcium levels of preschoolers were significantly lower than those of infants, whereas serum iron and ferritin levels were not. CONCLUSION: Hair calcium, iron, and copper concentrations were significantly lower in toddlers and preschoolers than in infants. Insufficient dietary intake of calcium and iron seems to be related with decreased hair mineral contents in young children.

Pulmonary vein velocities have recently been estimated in conjunction with mitral flow velocities to increase our understanding o ventricular filling. The advent of transesophageal echocardiography with pulsed Doppler imaging capability has provided a method by which both the mitral valve and pulmonary vein velocities can be easily recorded because of the posterior approach providing unimpeded interrogation of cardiac structures. The purpose of this present study was to evaluate the normal pulmonary venous, mitral and aortic flow pattern by transthoracic echocardiography in neonate according to the postnatal age. The results were as follows. 1) With regard to the aortic flow, the early systolic was of pulmonary flow peaked after the onset of aortic flow and the late systolic wave occured consistently before aortic valve closure. 2) The peak velocities of early systolic, late systolic, late systolic, diastolic and atrial systolic in the pulmonary venous flow were 36.4 (13.2cm/sec, 45.3 (15.3cm/sec, 48.5 (14.1cm/sec and 16.6( 5.7cm/sec at 1 day old. the difference according to the postnatal age was not significant. 3) The ratio of peak systolic to peak distolic velocity of pulmonary venous flow was 1.0( 0.3 at 1 day o1, 1.1( 0.4 at 1 week old and 1.2 (0.3 at 1 month old. The difference between old and 1 month old was statistically significant(p<0.05). 4) The peak early diastolic velocity of mitral flow was 51.3 (15.2cm/sec at 1 day old, 54.7( 13.7cm/sec at 1 week old and 80.7 (16.6cm/sec at 1 month old. The difference between 1 week old and 1month old was statistically significant(p<0.01). 5) The peak late diastolic velocity of mitral flow was 48.3 (14.6cm/sec at 1 day old, 50.1( 9.9cm/sec at 1 week old and 71.8 (16.6cm/sec at 1 month old. The difference between 1 week old and 1 month old was statistically significant(p<0.01). 6) The ratio of peak mitral early diastolic to peak late diastolic velocity was 1.1( 0.2 at 1 day old, 1.1( 0.3 at 1 week old and 1.2( 0.7at 1 month old. The difference between 1 week old and 1 month old was statistically significant(p<0.01). 7) The peak aortic valve flow velocity was 62.1 (14.2cm/sec at 1 day old, 67.8 13.4cm/sec at 1 week old and 76.6 14.1cm/sec at 1 month old. The difference between old and 1 month old was statistically significant(p<0.05). In conclusion, improvement of left ventricular diastolic function was noted at 1 month old by echocardiography. These normal data will be useful in comprisons with the data, which obtained in newborn with various congenital heart disease that affects flow dynamics.

PURPOSE: This descriptive correlation study was done to identify how perception of patient safety culture of general hospital nurses affects safety during nursing activities. Data from this study should provide information on management of patient safety as well as improvement in patient safety. METHOD: Participants in this study were 357 clinical nurses working in a general hospital in M city which had two medical evaluations. A survey was conducted to gather the data. RESULTS: The score for perception of patient safety culture of the general hospital nurses was 3.42, out of a possible 5 points, and the score for safety care activities was 3.90. There was a statistically significant positive relationship between the nurses' perception of patient safety culture and their safety care activities, Perception of patient safety culture, Supervisor/manager, communication and procedures, and frequency of accident reporting were factors that impacted significantly on safety nursing activity. CONCLUSION: The results of the study indicate that patient safety cultural perception significantly affects the safety of nursing activities and thus systematic educational strategies to increase perception should be provided to increase the level of patient safety culture. Also, other specific methods that increase the level of patient safety culture should be considered.

Pulmonary endometriosis is a rare disease which is characterized by hemoptysis during menstruation (catamenial hemoptysis). We report a case of pulmonary endometriosis in a 33-year-old housewife. She has had regular menses with moderate flow and minimal dysmenorrhea. She had undergone curettage in May 1995 for artificial abortion. In July 1995, she experienced the first episode of hemoptysis. A chest CT scan revealed a 2.0 1.0 cm sized ill-defined soft tissue density in the periphery of anterior segment of the left upper lobe with a surrounding irregular ground-glass opacity. A left upper lobectomy was done under the diagnosis of pulmonary endometriosis. Cut section of the resected lung showed a round red-brownish solid lesion, measuring 2.0x1.0cm in cross. Microscopically a focus of the endometrial tissue, which was composed of endometrial glands and stroma, was found in the lung parenchyme and many hemosiderin laden macrophages were seen in the surrounding alveoli. The postoperative course was favorable with no further episodes of hemoptysis.

Alzheimer's disease (AD) is an age-related disorder. Both the prevalence and the incidence of AD double approximately every 5 years after the age of 60. This is a particularly serious problem considering that the Korean elderly population is rapidly growing. We present three illustrative cases of AD in mild, moderate, and advanced stages, respectively. Their initial symptoms were memory impairment which was followed by language disturbance and visuospatial dysfunction. Abnormal behaviors such as delusion and aggression occurred in moderate and severe cases. The presence and severity of dementia in these cases were established by history taking, neurological examination, standardized mental status assessment, and neuropsychological test. Laboratory investigations showed no abnormalities that could account for the cognitive deficits. Brain CT or MRI findings of the patients wee not remarkable except for a diffuse atrophy demonstrated by increased ventricular volume, narrowed gyri, and widened sulci, As an addendum, risk factors, clinical symptoms, clinical diagnosis, and natural history of AD were reviewed.
