Purpose: In patients with chronic knee pain, the diagnostic performance of $^{99m}Tc-MDP$ knee SPECT for internal derangement of knee is deteriorated due to degenerative changes. In this study, we tried to establish diagnostic criteria to differentiate medial meniscal injury (MMI) from degenerative change (DC) when the uptake is increased in medial compartment. Materials and Methods: A total of 49 knee SPECT of the patients with chronic (more than 3 months) knee pain, which showed increased $^{99m}Tc-MDP$ uptake in the medial compartment, were included in this study. The diagnosis was confirmed by arthroscopy. On knee SPECT, 3 diagnosic criteria for MMI were investigated. In Criterion I, MMI was diagnosed when crescentic uptake was observed in the medial tibial plateau. In Criterion II, crescentic uptake was further classified into anterior, mid, posterior, and diffuse patterns, according to the location of maximal uptake; and only crescentic mid, posterior, and diffuse patterns were diagnosed as MMI. In Criterion III, MMI was diagnosed when medial tibial plateau showed higher activity then medial femoral condyle. The diagnostic performance of the 3 criteria was compared. Results: The sensitivity and specificity were 93% and 14% in Criterion I, 89% and 38% in Criterion II, and 75% and 67% in Criterion III, respectively. Criterion III had significantly improved diagnostic performance, especially, specificity. Conclusion: In this study, we established a practical diagnostic criterion to differentiate MMI from DC on knee SPECT. The result is helpful to improve the diagnostic value of knee SPECT as a screening test for chronic knee pain.

Objectives : The change of sleep patterns commonly occurs in association with the pregnancy. This study was to investigate sleep habits during the course of normal pregnancy. Methods : Sleep habits questionnaire was administered to healthy women in their first trimester(TR1) of pregnancy and then the same questionnaire was repeatedly administered during their second(TR2) and third(TR3) trimesters. The following aspects were assessed : patterns of night sleep, daytime status, sleep posture, reasons for sleep alteration, and the experience of any particular parasomnias, as well as sleep problem-related treatment or medication. Data analysis was based on 26 women who maintaind good health throughout their pregnancy and completed the questionnaire three times. Results : In comparisons between each trimester and non-pregnant state, total night sleep time, daytime tiredness, and sleepiness were significantly increased in all trimesters. Sleep latency was significantly decreased in TR1 and TR2, but not in TR3. In addition, refreshed feeling on waking the following day was significantly decreased and the number of awakenings during night sleep was significantly increased in TR3, but not in TR1 and TR2. In comparisons between trimesters, there was a significant increase in sleep latency, daytime sleepiness and the number of awakenings during night sleep and a significant decrease in refreshed feeling on waking the following day in TR3 compared to TR1 and TR2. Over the course of pregnancy, the rate of lateral position during sleep was gradually increased and all the pregnant women took the lateral sleeping posture in TR3. The major reasons for sleep pattern alteration were nausea, vomiting and heartburn in TR1, urinary frequency, fetal movement and ache in hips in TR2, and urinary frequency, fetal movement, cramp in legs and backache in TR3. Conclusion : These findings are expected to be useful for educating pregnant women about sleep hygiene. In future studies, the underlying factors and mechanisms regarding sleep patterns during pregnancy will need to be clarified.

The purpose of this study was to evaluate the individually perceived quality of life in Korean patients with BMS using two questionnaires : the Medical Outcome Short Form Health Survey Questionnaire (SF-36) and the Oral Health Impact Profile (OHIP-49). This cross-sectional study included sixty subjects diagnosed with BMS and sixty healthy subjects as controls. All subjects in this study completed two questionnaires: the Medical Outcome Short Form Health Survey Questionnaire (SF-36) and the Oral Health Impact Profile (OHIP-49), which had been translated into Korean and subsequently validated for use in Korea. All of the subscales in the SF-36 exhibited significantly lower scores in BMS patients than control groups. Comparison of the mean SF-36 scores between the two groups revealed the greatest differences to be for the subscales of physical pain and role emotional (role limitations due to emotional problems). The mean score on each subscale of the OHIP-49 was significantly higher in BMS patients than control groups. Comparison of the mean OHIP-49 scores between the two groups revealed the greatest difference to be for the subscale of physical pain. These findings demonstrated that BMS had an impact on various components of a patient's quality of life. BMS patients exhibited more impaired results and a poorer quality of life than control groups.

Purpose: Anatomical repair of massive rotator cuff tear has been technically challenging because of medial retraction, muscle atrophy and fatty degeneration. Among several treatment options for massive rotator cuff tear, we reviewed rotator cuff repairs and investigated modalities for improvement of clinical outcomes, decreasing the re-tear rate, and increasing healing. Materials and Methods: Patient-related factors and rotator cuff-related factors were the two major groups of factors we considered when choosing a treatment plan. Results: Mobilization of a massive rotator cuff tear was increased by soft tissue release and by the interval slide technique. After meticulous soft tissue release, anatomical repair could be achieved. If the injury was not amenable to anatomical repair, alternative treatment options such as partial repair, the margin convergence technique and augmentation with a tenotomized biceps tendon were considered. Many reports of massive rotator cuff repair demonstrated satisfactory clinical outcomes, decreased pain, recovery of shoulder functions, and increases in muscle strength. However, the re-tear rate had been reported to be relatively high in long-term follow-up. Conclusion: Despite a high re-tear rate after massive rotator cuff repair, a better understanding of the pathogenesis, progression and clinical symptoms of massive rotator cuff tear and improved surgical materials and techniques will lead to satisfactory clinical outcomes.

Purpose : The purpose of this study was to evaluate the gutter pathologies and the clinical results of arthroscopic treatment for ankle gutter syndrome. Materials and Methods : Seventy six patients(77 ankles) who had lesions in the ankle gutter were treated by arthroscopy. The gutter pathology could be divided into 3 categories; hypertrophic scar tissue, loose bodies and bone spurs. Fifty two patients were evaluated subjectively and functionally with authors' criteria. The follow-up period averaged 44 months(range, 2.9 year-8.5 year). Results : The incidence of the gutter lesion was $21\%$(77 ankles) among 366 ankles undergoing arthroscopy. The most common pathology was hypertrophic scar tissue. In 31 ankles$(40\%)$, the lesions were found only in gutter, and 46 ankles$(60\%)$ were associated with pathologies in other areas. All of parameters for subjective and functional evaluation were improved with statistical significance(p<0.001). Seventeen patients$(33\%)$ could returned to competitive or contact sports activity with same level of premorbid period. Conclusion : Ankle gutter is an important site of pathologies which cause chronic ankle pain, and should be explored in ankle arthroscopy. The ankle arthroscopy is a very effective treatment method fur the removal of pathologies in ankle gutter syndrome.

Objective: The purpose of this study is to find out the differences of clinical characteristics of endometriosis and to emphasize the significance of early diagnosis of endometriosis to protect disease progression in adolescents. Methods: A retrospective analysis was carried out. All cases (n=130) were diagnosed surgically as endometriosis between January 2000 and August 2007 in two university hospitals in Daegu. Adolescents were 23 cases and unmarried young women were 107 cases. Data were collected through review of medical records. Results: The predominant symptom in adolescents was cyclic pain. 52.2% of adolescent patients were stage I or II. And stage III was 47.8% but stage IV was none. The other side 82.2% of unmarried young women patients were stage II or III and stage IV was 15.8%. Serum CA-125 level was elevated in adolescents, also. But there was no significant difference between the two groups. Conclusions: Endometriosis is progressive disease. Early diagnosis is necessary for prevention of the disease progression and free from pain. Appropriate gynecologic examination and careful concerns about adolescents are mandatory.

Carbondioxide($CO_2$) laser is one of the most widely employed lasers in oral soft tissue surgery because of its excellent affinity for water based soft tissues. It has some inherent advantages such as hemostasis, less postoperative swelling, reduction of bacterial population at surgical site, less need for suturing, less scarring, and less postoperative pain compared to conventional surgical therapies including the use of scalpel, diathermy, cryotherapy and electrosurgery. A 30-years-old male was presented with gingival swelling. Clinical examination revealed a well?defined pedunculated fibrotic mass on the buccal gingiva near right maxillary 1st molar. In radiographic examination, no remarkable abnormality was seen. Excisional biopsy was performed with $CO_2$ laser (continuous wave mode, 4.0W). Histological diagnosis was "Irritation fibroma". $CO_2$ laser has advantages those are suitable for surgical treatment of intraoral lesion. If appropriate training and experience are provided, the dentist would be able to manage intraoral lesions more efficiently and successfully with the use of the $CO_2$ laser.

Dedifferentiated parosteal osteosarcoma is an uncommon variant of osteosarcoma. Dedifferentiation is known to be associated with a greater metastatic potential and a more rapid lethal clinical course. Thus recognition of dedifferentiation is important to establish the treatment strategy. But there may be few significant clinical clues to distinguish between dedifferentiated parosteal osteosarcoma and conventional one. A 29-year-old woman presented with 2-year history of discomfort and swelling in her proximal thigh. Examination showed a large, hard, non-mobile mass. Radiographs revealed a large ossified mass attached to the proximal femur. Diagnosis of parosteal osteosarcoma was established by MRI and needle biopsy. But she had a history of abrupt severe thigh pain and increased swelling before surgery. Follow up MRI showed enlargement of mass with invasion to muscle around tumor. The patient underwent an en-bloc resection of tumor and reconstruction. Histological examination showed parosteal sarcoma with dedifferentiation. The patient expired due to local recurrence of tumor and distant lung metastasis 2 months after the surgery. In case with rapid growth of a lesion or unusual severe pain, one must have a high index of suspicion with regard to dedifferentiation.

This study was conducted to evaluate the converge effects of the Be Happy and Strong (BeHaS) exercise program on female elders living alone, using a nonequivalent control-group pretest-posttest design. The BeHaS exercise program was conducted twice each week for 4 weeks (total 8 sessions). The outcome measures included pain, shoulder flexibility, grip strength, depression, and suicidal ideation. Independent t-test, Chi-squre test, paired t-tests and ANCOVA were used for the statistical data analysis. A statistically significant improvement emerged in pain (t=4.044, p=.000) and right and left shoulder flexibility (t=2.192, p=.038 and t=2.568, p=.016) 4 weeks later. In a group comparison, a statistically significant difference arose in changed scores of suicidal ideation (F=7.32, p=.010) between groups. The BeHaS exercise program may effectively improve the physical and psychological health of female elders living alone.
