In order to achieve a satisfactory esthetic result of periodontal surgery or implant in maxillary anterior area, periodontists must be aware of normal alveolar bone anatomy. The purpose of this study was to evaluate the relationship of alveolar bone morphology to tooth shape and form. 78(mean age : 25 yrs) periodontally healthy volunteers participated in this study. Two maxillary central incisor and one lateral incisor were selected to study. With minimal local anesthesia, guttapercha cone inserted to labial gingival sulcus of selected teeth just after bone sounding with periodontal probe. Metal ball (4mm diameter) attached to palatal fossa of central incisor. Then, periapical radiograph was taken according to long cone paralleling technique. After film scan, labial alveolar bone profile reproduced along interproximal bone and apical ends of gutta-percha cones on computer screen. By utilizing computer program, the distance from height of interproximal bone to the labial bone crest in central incisor-central incisor and central incisor-lateral incisor area was measured and converted to real distance by using vertical length of metal ball on film. After measuring crown length & width of central incisor, the 10 individuals ranked lowest CW/L ratio (crown width/length ratio) and the 10 ranked highest were selected as having a long-narrow(group N), or a short-wide(group W) form of the central incisors. Means of the distance from height of interproximal bone to the labial bone crest of group N, W were calculated and compared by means of independent t-test. The results were as follows: 1. Mean distance from the height of the interproximal bone to the labial bone crest was 3.5+/-0.7mm between two central incisor, and 2.8+/-0.6mm between central and lateral incisor. 2. Mean CW/L ratio of group N was 0.57, and group W was 0.8. Mean distance from the height of the interproximal bone to the labial bone crest of group N was higher than group W in both measured area(measurements of group N, W were 3.9+/-0.2mm and 3.5+/-0.2mm between two central incisor, 3.0+/-0.2mm and 2.8+/-0.2mm between central and lateral incisor), but there were no statistically significant differences when the groups were compared. Within the limits of the present study, there was a tendency that subjects with long-narrow teeth have more scalloped alveolar bone profile than subjects with short-wide teeth in upper anterior area, but no statistically significant differences were found.

The lung nodule is one of the pleuropulmonary menifestations in rheumatoid arthritis. We report here a case exhibiting hydropneumothorax due to a bronchoplerual fistula resulting from a ruptured rheumatoid lung nodule complicated with a aspergilloma in it. A 39 year-old man with rheumatoid arthritis was admitted because of cough for one month. Multiple subcutaneous nodules were noted and multiple lung nodules were seen on chest X-ray, Peripheral white cells were 9,600/mm3 with 1896 of eosinophils. The percutaneous needle aspiration biopsy of the largest lung nodule of right upper lobe showed massive necrosis without acid fast bacillus, fungus, or malignant cell. Three months after discharge, air-meniscus sign was seen on the biopsied lung nodule on X-ray. Five months later, the patient was readmitted due to dyspnea and chest pain and simple chest X-ray showed hydropneumothorax on the right side. The pneumothorax was not healed after closed thoracotomy and tube drainage, and high fever developed. The pleural fluid culture revealed Pseudomonas aeroginosa and Aspergillus fumigatus. Seventy days after admission, exploratory thoracotomy was done. Aspergilloma was found in the cavitated lung nodule which was ruptured into the pleural cavity through bronchopleural fistula.

Congenital cystic adenomatoid malformation(CCAM) is one of the most common congenital lung lesions. Clinical manifestations that show are neonatal respiratory distress, recurrent respiratory infection, pneumothorax, and hemothorax. But, there are patients who are asymptomatic until mid-childhood. The treatment of asymptomatic CCAM is controversial. There is a possibility to resolve it spontaneously, but late complications such as recurrent pulmonary infection, pneumothorax, hemothorax, and cancer, which includes bronchoalveolar carcinoma and rhabdomyocarcinoma, pleuropulmonary blastoma still remain. Some investigators advocate routine surgery for all cases of CCAM that are apparent at birth. A previously healthy 16-months-old girl who had suffered from a cough for 2 weeks was transferred to Asan Medical Center with CCAM. Due to a chest CT and fever, we first thought that she had CCAM with infection. After we treated her with antibiotics for one week, we performed surgery to confirm the diagnosis and to prevent further complication. But by surgical wedge resection, a pleuropulmonary blastoma was found. There were no evidence of metastasis and adjacent involvement. She started her chemotherapy with vincristine, actinomycin D and cyclophosphamide, and is now continuing maintenance chemotherapy with etoposide, vincristine, and Ifosfamide. We report pleuropulmonary blastoma that presented as CCAM. So we recommend surgical resection in asymptomatic CCAM to confirm the diagnosis and to prevent its malignant transformation, even not accompanied by symptoms.

Antiphospholipid syndrome (APS) is a noninflammatory autoimmune disorder characterized by the association of arterial and/or venous thrombosis, recurrent fetal loss and elevated titres of antiphospholipid antibodies, namely lupus anticoagulant (LAC) and/or anticardiolipin antibodies (aCL). It can either occur as a free-standing condition (primary APS) or be associated with another autoimmune disease (secondary APS), mainly systemic lupus erythematosus. The precise pathogenesis of thrombosis in APS in unknown. For children with unexplainable venous or arterial thrombosis, APS should be considered. The diagnosis of APS in children requires a clinical event including venous or arterial thrombosis or immune thrombocytopenia and a laboratory abnormality including positive LAC test or positive aCL antibody test, moderate or high titer IgG. The laboratory abnormality should persist for at least 2 months. We report a 7-year-old girl who had pulmonary embolism and multiple arterial thrombosis caused by primary APS. The laboratory abnormality was positive LAC and beta2-glycoprotein I. She was treated successfully with low molecualr weight heparin (LMWH). After recovery, she was continuously treated with subcutaneous LMWH for another 3 months and switched to oral warfarin. She was symptom-free through 3 years of follow-up.

PURPOSE: To evaluate two different heel lancet device in terms of pain response and success of the procedure in the preterm infants undergoing heel puncture. METHODS: 100 preterm infants undergoing capillary blood gas analysis or capillary bilirubin monitoring underwent heel puncture, were randomly allocated to blood sampling from the heel with either a conventional manual lancet or an automatic incision device. Primary outcome measures included the Premature Infants Pain Profile (PIPP) score, total duration of procedure, number of heel puncture and number of bruise. The pain response was evaluated using PIPP score and the effectiveness was evaluated using three criteria: total duration of blood sampling, number of puncture, bruising of the heel or ankle. Statistical analysis was performed using the SPSS ver. 13.0 program. Difference between the groups were analysed with t test (continuous variables) and the Chi square test or Fisher test (categorical variables). RESULTS: The mean PIPP score was 4.91 for the automatic lancet group compared with 5.84 for the conventional manual lancet group (P=0.0255).The number of pain scores above 7 during blood collection did not differ between two groups (P=0.2167). The procedure took less time to perform in the automatic lancet group (mean, 30.69 seconds) than in the conventional lancet group (mean, 48.92 seconds) (P<0.0001). CONCLUSION: This study demonstrated that the automatic lancet device causes less pain and a shorter procedure time than the conventional manual lancet in preterm infants undergoing heel puncture. On the basis of these results the automatic lancet device is very useful method for blood collection in preterm infants by heel puncture.

Purpose: This study was conducted to investigate the nursing needs and workload of nurses according to nursing dependency for effective placement of nursing staff in the emergency department (ED). Methods: In June 2020, 256 adult patients who visited the ED were classified as two groups, suspected COVID-19 patients and general patients. The participants’electronic medical records were analyzed using descriptive statistics, t-test, x 2 -test, and Fisher's exact test using the SPSS. Results: The patient dependence score showed a significant difference between the two groups, with an average of 13.99±1.85 for the suspected COVID-19 patient group and 10.58±2.10 for the general patient group (t=12.42, p<.001). There were statistically significant differences in communication (t=3.28, p=.001), mobility (t=3.29, p=.001), nutrition, elimination, and personal care (t=7.34, p<.001) among the six domains of nursing dependency. In the domains of environment, safety, health, and social needs, the dependency score was 3 for all suspected COVID-19 patients and 1 for all general patients. Conclusion The results of this study confirmed that infection control activities of emergency patients who need isolation affect the patients’ nursing dependency on nursing care.

BACKGROUND AND OBJECTIVES: The aim of this study was to investigate the effect of pulmonary valve replacement (PVR) on exercise capacity and determine cardiopulmonary exercise (CPEX) parameters associated with improvement in right ventricle (RV) function. SUBJECTS AND METHODS: We retrospectively analyzed CPEX and magnetic resonance imaging parameters in a total of 245 patients who underwent PVR from January 1998 to October 2015. In addition, we analyzed the characteristics of the patients who showed improved exercise capacity after PVR. RESULTS: Twenty-eight patients met the inclusion criteria for the study. CPEX parameters after PVR showed no significant changes in all patients. However, baseline predicted peak oxygen uptake (VO2(peak)) (%) value was significantly lower in patients with significant improvement in exercise capacity after PVR, as compared to patients who showed decreased exercise capacity after PVR (60.83±10.28 vs. 75.81±13.83) (p=0.003). In addition, patients with improved exercise capacity showed a positive correlation between the change of right ventricular ejection fraction (RVEF) (%) and the change of anaerobic threshold (r=0.733, p=0.007); whereas, patients with decreased exercise capacity showed a negative correlation between the change of RVEF (%) and the change of predicted VO2(peak) (%) (r=−0.575, p=0.020). CONCLUSION: The importance of predicted VO2(peak) (%) in evaluating exercise capacity differentiated from other CPEX variables. The change of anaerobic threshold and predicted VO2(peak) (%) might be a useful predictor of the change in RV function after PVR.

Intravesical instillation of BCG(Calmette-Guerin Bacillus) is the most widely used treatment of superficial transitional cell carcinoma of the bladder. While the exact mechanisms are not yet known, it is assumed that the recognition of tumor antigen is enhanced by immunologic response of the urothelium of mycobacterium. Various complications have been reported after BCG treatment and arthritis is observed in 0.5 to% of treated patients. This from of arthritis may be attributed to an antigen of mycobacterium sharing a cross reactive epitope with an antigen in articular cartilage. A 40-year-old male had transurethral resection and intravesical instillation of BCG for transitional cell carcinoma of bladder. Within few days of the fourth instillation, he developed arthritis on right knee and right metatarsal joint. Laboratory findings showed nonspecific inflammatory sign, positive HLA B27, negative rheumatoid facor and negative antinuclear antibody. The joint effusion was aseptic. He was treated with nonsteroidal antiinflammatory drugs (indomethacin 200rag/day) with resolution of arthritis symptom. We report a patient who developed an inflammatory oligoarthritis following intravesica] instillation of BCG for the treatment oof bladder cancer.
