Purpose: After periodontal surgery, studies have found that the use of periodontal wound dressing reduces the risk of wound infection and increases healing. The purpose of this study is to evaluate the effect of attachable periodontal wound dressing on the healing and patient satisfaction after periodontal flap surgery. Materials and Methods: Twenty-eight patients requiring periodontal surgery underwent periodontal flap surgery on both quadrants of maxilla or mandible. Postoperative pain, bleeding, dietary discomfort and hypersensitivity in relation to attachable periodontal wound dressing was assessed using Visual Analogue Scale (VAS). Additional survey on frequency of burning sensation and overall satisfaction rates were assessed. Results: VAS mean values for pain, bleeding, and dietary discomfort depending on the presence and absence of attachable wound dressing were; pain: 2.82, 3.96 (P = 0.002), bleeding: 1.61, 2.54 (P = 0.008), dietary discomfort: 2.82, 4.18 (P < 0.001), respectively. Test groups with attachable wound dressing reported significantly lower rates of discomfort. No significant difference was observed in burning sensation and hypersensitivity related with wound dressing. Satisfaction was higher in 75% of patients who received wound dressing. Conclusion: According to the results of this study, patients who received attachable periodontal wound dressing reported less postoperative pain, bleeding, and dietary discomfort. There was no statistical significance related to the use of wound dressing with burning sensation and hypersensitivity.

Purpose : This study was performed to investigate the prevalence of Staphylococcus aureus (S. aureus) nasal carriage in Korean children attending day care centers. Methods : During September and October 2009, a survey for nasal carriage of S. aureus and methicillin-resistant S. aureus (MRSA) was conducted among children attending day care centers located in Seoul with questionnaire survey for evaluation of risk factors of acquisition of MRSA was obtained from their guardians. A culture of the anterior nares swabs using enrichment broth was executed for isolating S. aureus and oxacillin susceptibility was assessed by the disk diffusion method. Results : Out of the 428 children enrolled whose mean age was 55 months old, 163 (38.1%) were colonized with S. aureus. Of the 163 isolates, 40 (24.5%) were MRSA. The nasal carriage rate of S. aureus showed an increasing trend with increase of age. Based on the answer to the questionnaire, 9.2% and 3.6% of children had a recent history of hospitalization and surgery, respectively, and approximately 40% of children had a history of prescription of antibiotics within 1 year prior to enrollment. Of the 428 subjects, 40 (9.3%) were MRSA nasal carriers. Conclusion : S. aureus and MRSA carriage rate of children attending day care center in Korea was 38.1% and 9.3%, respectively. Continued surveillance for nasal carriage rate of S. aureus and MRSA (especially community-associated MRSA) is mandatory.

Purpose : Vesicoureteral reflux(VUR) is defined as a retrograde flow of urine from the bladder into the upper urinary tract. It has been shown to predispose patients to hypertension, renal scarring, and end-stage renal failure if not recognized and treated. The observation that VUR occurs in siblings of children with reflux at a significantly higher rate than the general pediatric population has been recognized for many years and VUR was detected in 26% to 51% of siblings of patients with VUR. The purpose of this study is to determine the incidence of VUR in asymptomatic siblings of children with VUR and to see if this form of screening would be practical. Methods : We retrospectively reviewed the records of 28 patients with VUR and their siblings. The total number of asymptomatic siblings investigating VUR were 28 persons. All patients and siblings were evaluated for VUR by a voiding cystourethrography and all patients and siblings with VUR were performed $^{99m}Tc$ 2,3-dimercaptosuccinic acid renal scan. Results : A total of 28 patients(14 boys, 14 girls) with VUR were studied; the mean patient age was 2.7 years(range 1 month to 8.4 years). The total number of asymptomatic siblings investigating VUR were 28 persons(17 boys, 11 girls) and the mean age was 3.3 years(range 2 months to 7.4 years). Renal scar was detected in 20 of 28(71.4%) patients with VUR. VUR was noted in three of 28(10.7%) siblings and renal scar was detected in one of three siblings with VUR. Conclusion : In this study, the predictive value of a positive family history alone in identifying VUR was 10.7%. This incidence suggests more investigation of asymptomatic siblings and continued study of this group of patients at risk is needed for clarifying the family screening of patients with VUR.

Background: To assess the outcome of pulmonary resection in the management of hemoptysis caused by benign inflammatory lung disease. Material and Method: A longitudinal cohort study of 45 consecutive patients who were presented with hemoptysis and were treated with pulmonary resection from January 1995 to May 2004. The predictive preoperative risk factors of morbidity and recurrence of hemoptysis were analyzed. The mean age of the patients was 47.1 years. The mean follow-up was $35\pm34$ months. Result: The overall hospital mortality rate was $4.4\%(2/45)$. Postoperative complications occurred in 8 patients $(18.6\%)$. Complications were more common in patients who received blood transfusion than non-transfused patients (p=0.002). Patients with tuberculous destroyed lung disease had more amount of preoperative hemoptysis (p=0.002), more probability of transfusion (p=0.001), more probability of undergoing pneumonectomy (p=0.039) and more probability of postoperative morbidity. Patients of undergoing pneumonectomy had more probability of reoperation due to postoperative bleeding (p=0.047). Hemoptysis recurred in five patients but three had been subsided and two sustained during follow-up. A latter two patients had been prescribed with antituberculosis medication due to relapse of tuberculosis. Conclusion: A tuberculous destroyed lung disease has a higher rate of postoperative morbidity than other inflammatory lung diseases. A pneumonectomy in patients of inflammatory lung disease should be performed with great caution especially because of postoperative bleeding. Future study with longer and larger follow-up might show the reasons of recurrence of hemoptysis.

The purpose of this study were to analyze the home care services and to evaluate the client's satisfaction with the home care services provided by home care service center in the C hospital. The data were collected by reviewing charts of 128 home care clients who were receiving home care services at C hospital from October 1997 to September 2000. The subjects for satisfaction of home care service were 20 clients from July 10 to September 30, 2000. The tool for measurement of present condition of home care service was developed by the researchers. The satisfactions of the home care services were measured by using the instrument developed by Im(997). The data were analyzed by using the SPSS/PC+. The results of this study were as followings : 1. Majority of the subjects was female(61.7%). The average of age was 63.5 years. The service has been used mostly by the elderly 60 years of age or older(71.1%). The economic level of most of subjects was in middle class(94.5%). 2. Majority of the subject had a cancer(55.4%), following stroke(25.0%). The average duration of disease for the subjects was 31 months. The average time of hospitalization for the subjects was 3.3 times. The duration of hospitalization was 10$\sim$30 days(26.6%), 30$\sim$60 days(23.4%) and above of the 210 days(9.4%). 3. Most of the subjects used his/her doctor (47.7%), as a consultant, following his/her nurse (28.1%), other patients or their family (21.9%). Most of reasons for a consultation were supportive management(Infusion or medication, 60.94%), following tube management(L-tube or T-tube, 25%), Foley catheter management (15.63%) etc. 4. 28 types of nursing diagnoses were used by the home care service. The nursing diagnosis altered nutrition: less than body requirement were used mostly by the home care service, following risk for infection, impaired skin integrity, impaired swallowing, ineffective airway clearance altered comfort: pain, impaired physical mobility. By the human-response pattern, exchanging(63.2%), moving(7.5%), feeling(10.4%), knowing(5.2%), communicating (2.6%), relating(0.5%) perceiving(0.4%) and choosing(0.3%).

The national loss caused by the periodic livestock epidemic is very large. In addition, vehicle movement is the main cause of livestock epidemics in Korea. In this context, this study analyzed the relationship between the degree centrality of livestock facilities and the outbreak of infectious diseases. For this purpose, a livestock vehicle movement network was constructed using the facility entrance data provided by KAHIS. Afterwards, the centrality index was derived for each facility in the vehicle movement network and the mean centrality index of the epidemic and non-epidemic facilities were compared. The analysis results are summarized as follows. First, the degree centrality of epidemic facilities is significantly greater than non-epidemic facilities. As a result of the analysis of the entire period data and the period-based data, in most data, the degree centrality of facilities where livestock infectious diseases occurred was significantly greater than most non-occurrence facilities. Second, in the entire period data, the difference in degree centrality between the epidemic and non-epidemic facilities was smaller for HPAI than for FMD. On the other hand, no significant difference was found in the results of the analysis according to the divided period. The policy implications of the results are as follows. First, proactive management of facilities based on centrality is needed. Second, in the case of cloven-hoofed animal facilities, it is more urgent to introduce a management policy based on the degree centrality.

Background: Oral squamous cell carcinoma (OSCC) is the most prevalent malignancy among males in India. While tobacco and alcohol are main aetiological factors, human papilloma virus (HPV) presence has surprisingly increased in head and neck Squamous Cell Carcinoma (HNSCC) in the past two decade but its frequency in OSCCS is still uncertain. We aim to explore the frequency of HPV and its major genotypes in North Indian patients and their association with clinicopathological and histopathological features and p16 expression pattern. Materials and Methods: The study group comprised 250 histologically proven cases of OSCC. HPV was detected by real time PCR in tumor biopsy specimens and confirmed by conventional PCR with PGMY09/PGMY11 primers. Genotyping for high-risk types 16/18 was conducted by type specific PCR. p16 expression was assessed by immunohistochemsitry. Results: HPV presence was confirmed in 23/250 (9.2%) OSCC cases, of which 30.4% had HPV 16 infection, 17.4%were positive for HPV 18 and 26.1% had co-infections. HPV presence was significantly associated with male gender (p=0.02) and habit of pan masala chewing (p=0.01). HPV positive cases also had a history of tobacco consumption in 91.3% cases. p16 over expression was observed in 39.1% of HPV positive cases but this was not significantly different from negative cases (p=0.54). Conclusions: The frequency of HPV in OSCC is low in North-India and majority of cases are associated with a tobacco habit. It appears that tobacco shows a confounding effect in HPV positive cases and use of p16 protein as a reliable marker to assess the potential etiological role of HPV in OSCC in our population is not suggested.

Avulsion fractures of the intercondylar eminence of the tibia are not uncommon. In the displaced avulsion fracture, anatomical reduction and firm fixation of fracture fragments are needed but the most of the conventional operative techniques including arthroscopic technique are relatively complex and need. The results were not always satisfactory due to the risk of postoperative complications such as wound infection, premature epiphyseal closure and loss of fixation after early motion etc. So we describe a simple and safe modified method of arthroscopic reduction and fixation for avulsion fractures of the intercondylar eminence of the tibia. In our thirteen cases, we achieved anatomical reduction and secure fixation using cannulated screw through the three arthroscopic portals (anterolateral, medial mid-patellar and central). Postoperatively, immediate limited range of motion of the knee and partial weight bearing were possible. Additional use of the washer afforded safe fixation of comminuted avulsion fracture. The advantage of this technique includes its technical simplicity, easy removal of hardware, ability to treat comminuted type IV fracture with washer, no additional skin incision, no damage to growing plate in growth children and less morbidity.

Osseointegrated implnats have proven to be successful in both full and partial edentulous patients since the 1960s and recently have shown successful results when used to restore single tooth missing. However, in most studies reporting the success of single implants, single implants replacing anterior teeth are more frequently mentioned than posterior single implants. Moreover, in studies regarding posterior single implants, the replaced region seemed to be variable; the maxilla, mandible and areas from the first premolar to the second molar were mentioned. However, considering the difference in bone quality in the mandible and maxilla, and the increased occlusal force in the posterior region, the success rates in each region may be different. In this study, the cumulative success rates and amount of bone loss of single implants replacing the mandibular first and second molar, respectively, were compared and analyzed to come to the following conclusion. 1. The 20 (20 persons) single implants that were placed in the mandibular first molar region were all successful and showed a 100% 5 year cumulative success rate. Among the 27 (24 persons) single implants replacing the mandibular second molar, 8 failed (27.63%) showing a 5 year cumulative success rate of 70.37%. 2. Among the 8 failed implants, one showed symptoms of postoperative infection and one complained of parenthesia. 6 implants failed after functional loading; 5 showed mobility and one resulted in fixture fracture. 3. After the attachment of the prosthesis, there was no significant statistical difference regarding the marginal bone loss in group 1 and group 2 during the checkup period (P>0.05). In conclusion, restoration of the mandibular first molar using single implants was found to be an excellent treatment modality, and when replacing mandibular second molars with single implants, poor bone quality and risk of overloading must be considered.

By means of microsurgical free-tissue transfer providing a large amount of required tissue, the surgeon can resect tumoral tissue more safely, which allows tumor-free margins and enhances the reliability of the ablative surgery that otherwise could not be performed radically. The morbidity of elective free-tissue transfer seems to be quite low, carrying acceptable risks for most patients. But the elderly patients are at risk for cardiac and respiratory problems, deep vein thrombosis, pulmonary emboli and infection merely as a function of age. This study was undertaken to define further risks of the elderly population with regards to free-tissue transfer. We retrospectively reviewed our experience with 110 microsurgical free-tissue transfers for head and neck reconstruction in patients greater than 60 years of age. Microsurgical procedures in all cases were preformed by the plastic and reconstructive department at Yonsei medical center. The investigated parameters were patient demographics, past medical history, American Society of Anesthesiologists(ASA) status, site and cause of defect, the free tissue transferred and postoperative complication including free-flap success or failure. There were 46 patients in the age group from 60 to 64 years, 34 patients from 65 to 70 years, and 30 patients 70 years or older. There happened 3 flap losses, resulting in a flap viability rate of 97%. Patients with a higher ASA designation experienced more medical complication(p=0.05, 0.01, 0.03 in each age group I, II, III) but not surgical complication p=0.17, 0.11, 0.54 in each age group I, II, III). And the relationship between postoperative complication and age groups was not significant. These observations suggest that major determinant for postoperative medical complication be the patient's American Society of Anesthesiologists score, and chronologic age alone should not be an exclusion criterion when selecting patients for free-tissue transfer
