BACKGROUND: This retrospective comparative study aims to evaluate the surgical outcomes and complications of two surgical methods for simple fractures of the humeral shaft; minimally invasive anterior plating and open reduction combined with internal fixation. METHODS: A total of 26 patients with humeral shaft simple fractures, who had surgery between June 2009 and September 2013 and were followed-up at least 12 months, were included in our analysis. They were divided into two groups; group 1 comprised of 12 patients who underwent minimally invasive anterior plating and group 2 comprised of 14 patients who underwent an open reduction and internal fixation. The clinical outcomes, radiological results, and complications were compared and analyzed. RESULTS: We found that bone union was achieved in all patients, and the mean union periods were 20.7 +/- 3.34 and 20.3 +/- 3.91 weeks for groups 1 and 2, respectively. In most patients, we found that shoulder and elbow functions were recovered. At 12 months post-operation, we found that the Korean Shoulder Scoring system, the University of California at Los Angeles score and Mayo elbow performance score were 91.4 +/- 7.97, 33.4 +/- 1.15, and 90.8 +/- 2.23 for group 1, and 95.2 +/- 1.53, 33.3 +/- 1.43, and 90.17 +/- 1.85 for group 2. In terms of complications, we found that 2 patients had radial nerve palsy after open reduction and internal fixation, but all cases spontaneously resolved within 6 months. Complications such as infection and loss of fixation were not reported. CONCLUSIONS: Both minimally invasive anterior plating and open reduction with internal fixation produced satisfactory outcomes in the treatment of simple fractures of the humeral shaft.

Among the precancerous lesions, dysplasia of the uterine cervix and adenoma of the colon have been widely studied in terms of genetic alterations. However, little has been performed regarding phenotypic alterations of the precancerous lesions. We investigated the relationship among cellular proliferation, clonality, immortality and histopathologic grading of the squamous epithelial lesions of the uterine cervix. Proliferation index (PI) was calculated based on the ratio of the epithelial cells positive for proliferating cell nuclear antigen to the total epithelial cells. Clonality was assayed by X-linked HUMARA polymorphism. For immortality assay, PCR-based TRAP (telomeric repeat amplification protocol) was done and telomerase processivity was calculated by comparison with the positive control. PI increased gradually as the lesions advanced from dysplasia to invasive carcinoma. Among informative case, all of the carcinoma in situ showed monoclonal pattern (7 of 7). Among invasive squamous cell carcinoma, 6 cases showed monoclonal pattern and 2 cases polyclonal pattern. TRAP reaction was positive in 92.6% (25 of 27) of dysplasia (high grade: 14 of 15; low grade: 11 of 12), 95.0% (19 of 20) of carcinoma in situ, 100% (9 of 9) of microinvasive carcinoma, and 92.9% (13 of 14) of invasive carcinoma. It was also positive in 12 of 12 samples of chronic cervicitis or squamous metaplasia near the lesions of dysplasia. There was no difference in TRAP positivity among the dysplasia, carcinoma in situ and invasive carcinoma, whereas telomerase processivity showed significant correlation. These results suggest that proliferative activity and telomerase processivity may be progressive events in oncogenesis, although telomerase activation may be an early event.

The objectives of fusion surgery for spinal deformities include decompressing neural elements and achieving balanced spinal alignment. Particularly, in cases where spinal deformities coexist with osteoporosis, successful surgery requires careful consideration due to the susceptibility to fixation failure and non-union. Various efforts are being made to restore spinal alignment through surgery in osteoporotic patients. The administration of osteoporosis medications before and after surgery is effective for bony union. Additionally, appropriate selection of fusion range, rigid internal fixation, and utilization of bone substitutes play significant roles in successful fusion surgery. Although surgical treatment for spinal deformities accompanied by osteoporosis remains still challenging, we can anticipate successful outcomes with effective strategies and ongoing advancements in the future.

The purpose of this study was to analyze the minimum two year clinical and radiological results of revision total hip arthroplasties using allogenic chip bone graft and cement in acetabular bone deficiencies. Thirty six revision total hip arthroplasties that had been performed in thirty four patients between Sep. 1992 and May. 1994 at Seoul Paik Hospital and had followed more than two years were included in this study. The clinical result was evaluated by Harris hip score. The mean Harris hip score was 48 points preoperatively, 88 points at final follow-up, a mean of 3 years after revision. In radiological evaluation, osseous union between grafted bone and host bone was seen within 4 months in thirty two hips (89%), a complete grafted bone-cement radiolucent line of two millimeter or more in at least one zone was seen in seven hips (19%) and acetabular component migration was seen in six hips (17%) at postoperative 3 year follow-up radiograph. At the time of follow-up, five hips (14%) had been revised a second time: three for aseptic acetabular loosening, two for infection. In conclusion, we recommend the technique using allogenic chip bone graft and cement to reconstruct the acetabular bone deficiencies in revision total hip arthroplasties, though other technique will be recommend in severe segmental acetabular deficiencies or previous infection.

OBJECTIVE:
In Gunsan, Jeollabuk-do, Korea, we wanted to determine if the sluggish local economy could affect citizens' health behaviors, especially mental health.
METHODS:
We divided Gunsan-si into 5 living areas and conducted Small-Area Estimations and confirmed the modified compound estimation value using the 2013-2017 Community Health Survey data and population data from Gunsan-si.
RESULTS:
The health behaviors and mental health of the residents of the western living area(Soryong-dong, Misung-dong), which is an industrial hub of Gunsan, had deteriorated or decreased compared to those of other regions.
CONCLUSIONS
Although there are limitations in analyzing the community health survey data using the small-area estimation method, it could be useful data for evaluating regional gaps and health level.

To evaluate the effect of cetylpyridinium chloride in a powder form when used concomitantly with a conmercial fleuride containing tooth paste on inhibition of plaque formation, on gingivitis, and on irritation of oral mucosa. a double-blind, randomized parallel study was set up. Cetylpyridinium chloride was incorporated into a light brown colored powder with menthol added for scent. There were no differences between the active agent and the placebo which did not contain cetylpyridinium chloride in appearance, color, smell, taste, or dispenser. 98 healthy volunteers were assigned to one of two groups: brushing 3 times a day with flouride toothpaste and cetylpyridinium chloride powder, or brushing 3 times a day with flouride toothpaste and placebo. Before the test period, the subjects received through tooth cleaning and polishing. At basteline, GI, PI, BOP, and GCF of the Ramfjord teeth were measured in the experimental and placebo groups including 58 and 42 subjects repectively. After 4 weeks, GI, PI, BOP, GCF, compliance, irritation of the oral mucosa(redness, pus drainage, edema) and adverse reactions were measured. The PI, GI, and BOP of the experimental group recorded at baseline are 0.19+/-0.19, 0.42+/-0.31, and 0.08+/-0. 15. These scores showed significant decrease after 4 weeks of test period(0.11+/-0.15, 0.22+/-0.24, 0.02+/-0.09 repectively at the end of the study) and inhibition of plaque accumulation and resolution of gingival inflammation could be observed. GCF shoed slight increase but this was not Statistically different. Comparison of changes in measured scores of control and experimental groupshow GI, PI of the test indices have decreased. Test group showed significantly greater decrease in gingivitis and plaque accumulation after 4 weeks. GCF and BOP also showed greater decrease thant the control group but this difference was not statistically significant. At no time of the study period did any of the subjects show signs of irritation of the oral mucosa or adverse reactions. Following conclusions could be obtained from this study. The combined use of cetl powder and flouride toothpaste showed greater inhibition of plaque accumulation and greater decrease of gingivitis than use of flouride toothpaste with placebo agent.

STUDY DESIGN: A retrospective study OBJECTIVES: In the operative treatment of lumbar spinal stenosis, the wide decompression and fusion method has many problems, such as a long operation time, large blood loss and the long time required to achieve solid fusion. As a solution to these problems, a minimal decompression method was been performed, which minimizes the resection of laminae and facet joints. SUMMARY OF LITERATURE REVIEW: In the operative therapy for lumbar spinal stenosis, favorable results can be obtained by simple decompression. MATERIALS AND METHODS: 42 cases of degenerative lumbar stenosis, with neither segmental instability nor spondylolisthesis, underwent a minimal decompressive surgery, without instrumentation. The mean operation time and amount of blood loss were analyzed, and the clinical results evaluated according to Kim's criteria and the postoperative segmental instability by the Dupuis method. The average follow-up period was 70 months. RESULTS: Transfusions were not required in all cases. The mean operative times were 1hour 5minutes and 1hour 46minutes in the one and two segment decompressions, respectively. The clinical results, according to Kim's criteria, were excellent in 24 cases and good in 12. There was no dynamic instability in the radiographs at the last follow-up. CONCLUSIONS: With the degenerative lumbar stenosis, without segmental instability or spondylolisthesis, minimal decompression was an effective surgical method.

It was the late Chosun Dynasty and Daehan Empire era that Western Medicine has firstly been introduced to Korea, previously operating on a basis of Korean traditional medicine. Western Medicine has been introduced by American missionary and Japanese Imperialism. An introduction of Western Medicine made it feasible to proceed new type medical care including operation, leading to require a new form of medical facilities. In the beginning, new facilities were constructed by Japanese Imperialism. Other hand many of facilities including Severance Hospital were established by missionaries. First of all, Daehan Empire established and managed a modern type of medical facility named "Jejoongwon" in 1885 as a government institution hospital. The Red Cross Hospital built in 1889. Afterwards, Jejoongwon and the Red Cross Hospital were taken over to missionary hospital and Japanese Imperialism, respectively. Japanese Imperialists firstly have protected their nationals residing in Chosun but have proceeded care a few Chosun people to exploit medical treatment as a mean to advertise superiority of the Empire of Japan. The facility that has firstly been established and managed was Jeseang Hospital in Busan in 1877, leading to establish in Wonju, Wonsan, and Mokpo. Afterwards, Japan has organized "Donginhoi" as a civil invasion organization, leading for "Donginhoi" to established "Dongin Hospital" in Pyeongyang, Daegu, and Seoul. Since 1909, governmental leading medical facility named Jahye Hospital was established according to an imperial order, leading to establish 32 hospitals all over the nation. American missionaries have established and managed 28 hospitals started from Severance Hospital built in 1904. However, Chosun doctors started to having educated and opening up their own hospital since 1920, leading for many of medical facilities to be established, but most of them have taken different roles followed by 6.25 War and economic development period. However, some of them are currently under protection as cultural assets, and some of them are now preserved. Buildings have originally been structured of wood as a single story in the beginning, but bricks started to be steadily used, leading to build two story building. Each of clinic department started to be separated since 1920, establishing operation room and treatment room. Now, a change of perception as to buildings that need to be preserved and an attention from government and doctors are required since modern medical facilities keep disappearing.

BACKGROUND: Previous studies have shown that if performed without radiographic guidance, the loss of resistance (LOR) technique can result in inaccurate needle placement in up to 30% of lumbar epidural blocks. To date, no study has shown the efficacy of measuring the depth of the posterior complex (ligamentum flavum, epidural space, and posterior dura) ultrasonographically to distinguish true and false LOR. METHODS: 40 cervical epidural blocks were performed using the LOR technique and confirmed by epidurograms. Transverse ultrasound images of the C6/7 area were taken before each cervical epidural block, and the distances from the skin to the posterior complex, transverse process, and supraspinous ligament were measured on each ultrasound view. The number of LOR attempts was counted, and the depth of each LOR was measured with a standard ruler. Correlation of false and true positive LOR depth with ultrasonographically measured depth was also statistically analyzed. RESULTS: 76.5% of all cases (26 out of 34) showed false positive LOR. Concordance correlation coefficients between the measured distances on ultrasound (skin to ligamentum flavum) and actual needle depth were 0.8285 on true LOR. Depth of the true positive LOR correlated with height and weight, with a mean of 5.64 +/- 1.06 cm, while the mean depth of the false positive LOR was 4.08 +/- 1.00 cm. CONCLUSIONS: Ultrasonographic measurement of the ligamentum flavum depth (or posterior complex) preceding cervical epidural block is beneficial in excluding false LOR and increasing success rates of cervical epidural blocks.

Purpose: The purpose of this paper is to clinically evaluate the usefulness of all arthroscopic repair with biceps incorporation in massive sized full thickness rotator cuff tears. Materials and Methods: This is a prospective comparative outcome study evaluating a series of all arthroscopic rotator cuff repairs with biceps incorporation on massive (range: 5~6 cm sized) from March 2003 to May 2006. Group I was twenty two cases of arthroscopically repaired with biceps incorporation, twenty cases of group II without biceps incorporation were analyzed. The average age of the patients was 58 years (range, 41~74 years), and mean follow-up was 24 months (range, 12~36 months). Results were statistically compared by Mann-Whitney test. Results: Average VAS for pain, ADL, UCLA score were not significantly different between group I and group II (P>0.05 for each). Forward elevation strength was 4.3 in group I, 3.5 in group II (P<0.05). On postoperative follow up ultrasound, retear was 10 cases in the middle of 19 cases at group I, 15 cases in the middle of 17 cases at group II (P<0.05). Conclusion: This study reveals that all arthroscopic repairs with biceps incorporation in massive sized full thickness rotator cuff tears is an effective surgical method and reduced retear and enhanced strength.
