  • Purpose: To investigate the early results of limited open repair technique of Achilles tendon ruptures, and to describe the surgical technique. Materials and Methods: From October 2004 to February 2005, a total of 10 patients with Achilles tendon rupture underwent limited open repair. The average age of the patients was 39.3 years, and the average follow-up period was 9 months. The causes of injury were sports injuries in 8 cases, and slip down in 2. The mean interval between the injury and the operation was 9 days. The clinical results were assessed by patient's satisfaction, incision length, hospitalization, the ankle-hindfoot scale of American Foot and Ankle Society (AOFAS), and complications. Results: Of 10 patients, 8 were very satisfied, and the remaining 2 were satisfied. The mean incision length was 2.0 cm, and the mean hospitalization was 2 days. The mean AOFAS score was 97 points, and there was no complications such as infection, rerupture, or nerve injury. All patients returned to work at approximately 2 months, and resumed light exercise such as jogging at approximately 3 months. Conclusion: Limited open repair technique of Achilles tendon ruptures is provided for better cosmetic results, high patient's satisfaction, and functionally successful results without postoperative complications.

  • To evaluate anesthetic effecto of propofol infusion after premedication with xylazine, 20 days were randomly assigned 4 groups. Propofol was infused (group 1: 0.2 mg/kg/min, group 2 : 0.4 mg/kg/min, group 3 : 0.6 mg/kg/min, group 4 : 0.8 mg/kg/min) for a period of 90 minute immediately after premedication with xylazine(1 mg/kg) and atropine(0.05mg/kg) under oxygen supplementation. Induction of anesthesia was rapid and smooth providing satisfactory conditions for intubation in all the dogs. No vomiting and cyanosis were observed after induction and during propofol infustion. There was pain reflex in group 1 but not in group 3 and 4. Mean arousal times (mins) were $6.18{\pm}3.65(group 1), 13.07{\pm}5.05(group 2), 22.06{\pm}6.48(group 3) and 23.33{\pm}9.28 (group 4) and Mean walking times were 16.20{\pm}6.15(group 1), 15.80{\pm}4.73(group 2), 28.27{\pm}7.55 (group 3), 39.10{\pm}13.75$ (group 4) respectively. In group 4, body temperature during total infusion period in group 3, 4. Hematologic values (WBC, RBC, PCV) and serum chemistry values(ALT, AST, BUN, creatinite) were monitored before anesthesia, 1 hour and 1 day after termination of infusion postanestesia. No significant changes were monitored in all experimental group. Although propofol infusions of 0.2 mg/kg/min and 0.4mg/kg/min were considered too low to maintain a suitable depth of anesthesia, but that of 0.6mg/kg/min were considered too low to maintain a suitable depth of anesthesia, but that of 0.6mg/kg/min proper to provide a light planes for minor surgical procedure during 90 minutes with xylazine premedication.

  • 칼돌기 부위에 고통을 느끼는 칼돌기 통증은 흔하지 않은 근골격계 질환으로 전흉부와 상복부, 목, 양측 어깨, 등으로 통증이 방사될 수 있다. 진단에서 중요한 것은 이러한 통증이 칼돌기의 이상에 의해서 발생할 수 있다는 것을 임상적으로 알고 있어야 한다는 것이다. 2 증례의 칼돌기 통증 환자를 경험하였는데, 칼돌기 부위를 가볍게 누르면 전흉부와 상복부의 통증이 반복적으로 재생산될 때 진단하였다. 수년간 칼돌기 통증으로 고통 받아 왔던 첫번째 증례 환자에서는 칼돌기 제거수술을 하였고, 두번째 증례 환자에서는 국소마취제를 주사하여 치료하였다.

  • The study was designed to analyse the reorganization of the rabbit TMJ meniscus which was anteriorly displaced by surgery. The author compared the anteriorly displaced groups with control group. After surgical opening of the left rabbit TMJ space, cut the posterior attachment of the meniscus, and pushed it under the undercut area of the condyle head. Experimental groups were sacrificed by 1, 2, 4, 8 weeks after surgery. The samples were analysed with light microscope under T-B stain and electron microscope. The results were as follows: 1) The rabbit TMJ meniscus consisted of thick anterior and posterior band running different way, and comparative thin intermediate band runining antero-posteriorly. 2) Round oval shape chondrocyte-like cells were imbeded between the collagen fiber bundles and composed of proteoglycan granules, that showed metachromasia with toluidine blue, around the cell matrix. 3) Type II collagen fiber bundles in experimental group occured degenerative changes in organic patterns at 8 weeks, but those of type I collagen fiber bundles sustained longer, 4) The typical fibrocartilage of the rabbit TMJ meniscus was changed into fibrotic mode in process of time and showed the degenerative changes, which contained hyperplasia, calcification, resorption and hyalinization in the connective tissue. 5) The hyperplastic change of the synovial membrane in 4 week group and transitional change from fibrocyte to chondrocyte in cell type in 8 week group were observed. 6) The diameters of collagen fibers were diminished with the degenerative changes, the shape of the fibers became wavier and more nonorganic in running pattern and fiber bundle spaces widened.

  • The purpose of this study was to observe the effect of $TGF-{\beta}1$ on the regeneration of bone in guided bone regeneration. Four adult dogs aged 12 to 24 months were used in this study. Experimental bone defects were created surgically with surgical bur and chisel on the 3th. premolars. In experimental group, bone defect were grafted with DFDB and $TGF-{\beta}1$. In control groups, bone defects were grafted with only DFDB. At 1,2,3 and 4 weeks, dogs were serially sacrificed and specimens were prepared with Hematoxylin-Eosin stain and Goldner's stain for light microsopic evaluation. The results of this study were as follows: 1. The infiltration of inflammatory cells was prominent in control groups at 1, 2 and 3 weeks. 2. The lining of osteoblast was observed at 2 weeks in control group, but at 1 week in experimental group. 3. In both groups, osteoid was formed at 2 weeks. In control groups, osteoid was fromed on only bone surface. but in experimental groups, osteoid were formed on both bone & DFDB surfaces. 4. In only experimental groups, The fusion of new bone & DFDB was only observed at 3 weeks. and the fusion of new bone & DFDG was more prominent at 4 weeks. But in control groups, No fusion of new bone& DFDB was oberved at 3 and 4weeks. From the above result, the $TGF-{\beta}1$ was effective in bone formation and increased inductive effect of DFDB in guided bone regeneration technique. Inductive effect of DFDB was increased with $TGF-{\beta}1$.

  • Recently, dental laser have been applied for removal of soft tissues, hemostasis and blood coagulation, removal of benign and malignant tumor, treatment of leukoplakia, aphthous ulcer and herpetic lesion, implant second surgery, removal of granulation tissue, frenectomy, clinical crown lengthening, gingivectomy, gingivoplasty, and treatment of dentin hypersensitivity. Even though the frequency of laser treatment is increasing, the research on the healing process after gingivectomy using pulsed Nd : YAG laser is very rare. The purpose of this study was to observe and compare the wound healing after gingivectomy using scalpel and pulsed Nd : YAG laser in the rat. Gingivectomy was performed using pulsed Nd : YAG laser(SUNRISE Technologies, U.S.A., 1.5 Watts, 10 pps) on the buccal gingiva of right maxillary first molar and using scalpel(No.12) on the contralateral side. Those sites treated by surgical scalpel were designated as the control, and by pulsed Nd : YAG laser as the experimental group. Animals were sacrificed at 1, 2, 3, 5, 7, 11 and 14 days postoperatively, and specimens were histologically observed under light microscope. The results were as follows : 1. Clinical observation Normal color and shape were observed at the 5th day ill the control group and the 7th day in the experimental group. 2. Histologic findings 1) In the control group, denser inflammatory infiltration was observed. 2) Epithelialization started at the 2nd day in the control group, similar to the experimental group, and completed at the 11th to the 14th day postoperatively. 3) In the experimental group, connective tissue showed the vacuole formation and degenerative change during early healing period. Healing of connective tissue was slower in the experimental group than in the control group by 2 days. 4) In the both groups, wound healing was completed at the 2nd week. From this study, gingivectomy using pulsed Nd : YAG laser seems to result in a little delayed wound healing process, compared to the gingivectomy using scalpel. Considering the clinical advantages of laser surgery, pulsed Nd : YAG laser might be useful device for gingivectomy.

  • The rising trend of breast cancer both in developed and developing countries is a real threat challenging all efforts to screening, prevention and treatment aspects to reduce its impact. In spite of modern preventive strategies, the upward trend of breast cancer has become a matter of great concern in both developed and developing countries. Chittaranjan National Cancer Institute is a premier regional cancer institute in eastern region of India catering to a large number of cancer patients every year. A pilot case control study of fifty breast cancer patients and 100 matched controls was conducted during 2013 to evaluate the effects of habitual factors like working in night shift, not having adequate sleep, and not sleeping in total darkness on breast cancer of women. The study revealed that not sleeping in total darkness was associated with higher odds of outcome of breast cancer of women. This positive correlation can play a vital role in formulation of preventive strategies through life style modification.

  • Breast cancer treatment-related lymphedema (BCRL) is a common comorbidity in breast cancer survivors. Although magnetic resonance imaging (MRI) is widely used to evaluate therapeutic response of patients with various medical conditions, it is not routinely used to evaluate lymphedema patients. We conducted a systematic review of the literature to identify studies on the use of MRI to evaluate therapy for BCRL. We hypothesized that MRI could provide information otherwise not possible through other examinations. On October 21, 2019, we conducted a systematic review on the PubMed/MEDLINE and Scopus databases, without time frame or language limitations, to identify studies on the use of MRI to evaluate therapy for BCRL. We excluded studies that investigated other applications of MRI, such as lymphedema diagnosis and surgical planning. Of 63 potential articles identified with the search, three case series fulfilled the eligibility criteria. In total, 53 patients with BCRL were included and quantitatively evaluated with MRI before and after manual lymphatic drainage. Authors used MRI or MR lymphagiography to investigate factors such as lymphatic vessel cross-sectional area, tissue water relaxation time (T2), and chemical exchange saturation transfer. The only study that compared MRI measurement with standard examinations reported that MRI added information to the therapy evaluation. MRI seems to be a promising tool for quantitative measurement of therapeutic response in patients with BCRL. However, the identified studies focused on only manual lymphatic drainage and were limited by the small numbers of patients. More studies are necessary to shed light on the topic.

  • Purpose: Fingertip injuries are the most common hand injuries and may lead to significant disability. Knowledge of fingertip anatomy is mandatory to treat these injuries effectively. All surgical techniques used for coverage of fingertip injuries must be based on the nature of the injury and the patient's age. Many authors have studied the method of fingertip reconstruction because goals of these treatments should include maintaining length, sensibility, motions, and appearance. The purpose of this study is to evaluate the effect of digital artery perforator flap for fingertip reconstruction without aesthetic and functional problems. Methods: From November 2006 to March 2007, the authors performed fingertip reconstruction on 3 fingers of 3 patients, aged between 41 to 54 years (average age, 47 years) using digital artery perforator flap. Results: All fingers recovered successfully and there were no necrosis of the flap. We followed up 3 cases more than 5 months. Light touch and temperature sensation could be detected in all flaps and the static two-point discrimination test was 8 mm. Conclusion: This flap is an alternative choice for coverage of fingertip defects. This method also takes short time to procedure and to recovery. The digital artery perforator flap has never been reported in Korea, however it is considered as a useful method for treatment of fingertip injury.
