1.A Retrospective Study of the Clinical Outcome of Guided Tissue Regeneration in infrabony defects.
The Journal of the Korean Academy of Periodontology 1997;27(3):525-532
The purpose of this study was to evaluate the extent and predictability of periodontal regeneration with barrier membranes in deep infrabony defects. 25 patients(40% smokers) were included in this study. Fourty-one deep infrabony defects treated with membranes(PPD>6mm) were evaluated 1 year postoperatively following a plaque control regimen. Probing pocket depth(PPD), gingival recession(REC), and probing attachment level(PAL) were evaluated at baseline and postoperative 1 year. Plaque score at baseline was 16.2 and plaque score at 1 year was 9.9 A PAL gain of 4.1+/-2.5mm along with a PPD reduction of 5.0+/-2.3mm were observed. A PAL gain of 4.1+/-2.5mm was observed at the smoking group and a PAL gain of 4.0+/-2.5mm was observed at the non-smoking sroup. It was concluded that periodontal regeneration with membrane represented the predictable and effective treatment modality in the deep infrabony defects.

2.Combined Mucinous Tumor and Carcinoid of Appendix Associated with Mucinous Tumor of Ovary and Pseudomyxoma Peritonei: A case report .
Korean Journal of Pathology 1999;33(11):1094-1096
We report a case of mucinous cystadenoma of uncertain malignant potential and carcinoid of appendix associated with bilateral mucinous cystadenoma of ovary and pseudomyxoma peritonei. The patient was a 46-year-old female. She suffered from dyspnea and lower abdominal palpable masses for several months. Ultrasonogram showed multilocular huge ovarian cysts. Appendectomy, transabdominal hysterectomy, bilateral salphingo-oophorectomy and biopsy of omentum were performed. The bilateral ovaries measured 16 11 cm and 7X5 cm in size, respectively. The both ovaries showed multilocular cysts filled with thick mucus material. The ovarian cysts were covered by a single layer of columnar epithelium with focal proliferation. Mucus materials dissected through the ovarian stroma (pseudomyxoma ovarii). The tip of appendix was dilated and covered by mucus material. The cut surface showed a cyst and a yellowish solid mass proximal to the cyst. Microscopically, the appendiceal cyst was lined by stratified columnar epithelium with moderate cytologic atypia. Mucus material dissected through the wall. In the proximal portion of the appendix, a classic carcinoid with focal tubular form was present in submucosa and muscle layer. The omentum was covered by thick mucus material. Microscopically, the omentum showed mucinous epithelium and mucus material (pseudomyxoma peritonei).

BACKGROUND: Direct observation of healthcare workers is commonly used in hospitals to investigate hand hygiene compliance. However, the hand hygiene compliance rate may increase due to the Hawthorne effect, which is the modification of behavior simply because subjects become aware that they are being observed. The objective of this study was to investigate the occurrence of the Hawthorne effect when directly observing hand hygiene compliance in intensive care unit (ICU) healthcare personnel. METHODS: A total of 87 staff members from the coronary care unit and cardiac surgery ICU of a general hospital in Seoul were included in this study: 24 residents and interns, 55 nurses, and 8 nursing assistants. Both covert and overt observations, where subjects were either unaware or aware of any direct observation, were performed on separate occasions. RESULTS: A total of 1,052 covert and 1,336 overt observations were documented over 30 and 34 occasions, respectively. Overall hand hygiene compliance was significantly higher with overt observation than with covert observation (1,041/1,336, 77.9% vs. 659/1,052, 62.6%, P<0.001). The Hawthorne effect was present in all professions and behaviors, with the exception of nursing assistants, and prior to touching a patient. CONCLUSION: Direct observation of hand hygiene compliance was associated with the Hawthorne effect when observations were made overtly and this was likely to contribute to an overestimation of compliance rate.

A 62-year-old woman without vascular risk factors presented with left-sided weakness and numbness.
Magnetic resonance imaging (MRI) brain depicted acute right hemispheric infarcts in the cortical and
subcortical white matter. Initial MR angiography (MRA) showed large thrombus at the right carotid
bifurcation. Valvular atrial fibrillation (vAF) with severe tricuspid regurgitation (TR) was found on
two-dimensional echocardiography. Serial follow-up computed tomography angiography (CTA) or
MRA at 3, 9, and 15 days after anticoagulation alone showed complete resolution of the thrombus
with no neurological deterioration. Our case suggests that prompt institution of anticoagulantion alone
may result in radiologic resolution of the thrombus with improvement in patient’s clinical status.

Decubitus ulcer is often seen in the skin and underlying tissue of debilitated or immobilized patients as the result of prolonged pressure and impaired circulation. It manifests chiefly as an ulcer over bony prominences, but tumefaction is an extremely unusual presentation. A 53-year old male, a paralytic of the lower extremity for 18 years, developed a recurrent decubital ulcer despite repeated surgical repair, from which a rapidly growing, large fungating mass grew within a month. The last resected mass was bosselated and measured 15x9x3 cm with a major area of cicatrix-like induration, interdigitated with skeletal muscle bundles at the central area. Microscopically, the mass was composed of an upper half of active granulation tissue layer and a deeper half of dense, poorly cellular, fibrocollagenous bundles admixed with florid proliferation of atypical fibroblasts, but the absence of mitosis and the multifocal admixture of active inflammatory process-granulation tissue formation seemed to help exclude genuine fibromatosis, nodular fasciitis or proliferative myositis. We assume that this rapidly growing pseudofibromatosis is an additional manifestation of a prolonged decubitus ulcer, possibly related to the modified reparative process of decubitus ulcer following repeated excisions, for which we propose a term of decubitoma.

BACKGROUND: This study tested the efficacy of 0.12% chlorhexidine gluconate for improving oral hygiene in intubated intensive care patients. METHODS: In a group of 57 ventilated patients, 29 received normal saline (NS) for oral hygiene, and 28 were treated with chlorhexidine gluconate (CHG). Data on oral bacterial colonization was collected for 11 months from October 2005 to August 2006. Tests of oral hygiene and oral microorganism culture were performed on the day of the ventilation, and repeated on days 4, 8, and 12. RESULTS: Oral hygiene was significantly improved in the CHG group compared to that in the NS group (P<.001). Further, all patients (100%) in the NS group tested positive for Staphylococcus aureus on the 12th day after the endotracheal intubation, whereas only 42.9% (P=0.026) of the CHG group were positive. The NS group also had higher isolation rates of Pseudomonas aeruginosa at 66.7% on the 8th day after intubation and 87.5% on the 12th day. At these same intervals, the CHG group had isolation rates of 29.4% (P=.028) and 14.3% (P=.010) respectively. CONCLUSION: The longer the period of endotracheal intubation, the more effective the 0.12% CHG treatment was for improved oral hygiene and reduction of S. aureus and P. aeruginosa colonization when compared to treatment with NS.

Journal of the Korean Radiological Society 1995;33(3):457-463
PURPOSE: To evaluate mammographic and sonographic breast parenchymal changes and the risk of breast cancer in women on hormonal replacement therapy (HRT). MATERIAL AND METHODS: The study group consisted of 50 patients examined with serial mammograms and/or ultrasonograms during HRT. The control group consisted of 50 patients examined with serial mammogram for a routine health check. Mammographic parenchymal changes in both the study and control groups and so- nographic findings of 27/50 patients in study group were evaluated. RESULTS: Follow-up mammogram of the control group showed no interval change or slight evolution of parenchyma with increasing age, but the study group showed increasing parenchymal densities. Most frequently encountered finding on SOhogram in 11 women treated by estrogen alone, was ductal dilatation (7cases ;64%), whereas in 16 women treated by estrogen and progesteron it was ductal epithelial hyperplasia (8 cases; 50%). Overall, four breast cancers developed;one infiltrating ductal carcinoma and three ductal carcinoma in situ. CONCLUSION: HRT causes the changes of breast parenchyma on mammogram and sonogram of postmenopausal women, and increases the risk of developing breast cancer. Therefore, careful and regular examination should be followed in those on postmenopausal HRT.

Journal of the Korean Radiological Society 1985;21(5):751-754
Cardiac size of 291 new-born infants was measured using the method illustated on Fig 1. Among the 291 infants,53 were asphyxiated, and asphxia was only regared from Apgar score below 6 on 1 min. and 5 min. Remaining 238infants were normal, and classified to group with lung abnormalities and without lung abnormalities on chest A-Pfilm. The results are as follows; 1. The average CTR. of normal group was 52.37(C/T1;54.89, C/T2;49.43, C/T3;49.15, C/T;55.97) 2. The average CTR. of asphxiated group was 54.91 (C/T1;57.13, C/T2;51.69, C/T3;51.94,C/T4;58.25) 3. Consequently, asphyxiated infants revealed larger cardiac size than normal infant group.
