As a new concept of resistive exercise, isokinetic exercise was developed during the early 1950's. In isokinetic exercise, the subject works at a fixed speed against variable and totally accommodating resistance. The isokinetic equipment has been used widely as a therapeutic modality in clinical setting, as a training and testing device for sports practicians, and as a method for scientific examination of postoperative status of muscles and joint function for orthopedists. In order to acquire the isokinetic normative data of the knee for clinical use, we examined the flexor and extensor muscle force of the knee joint in 160 subjects with Cybex II. The results were as follows; 1. Mean values of extensor strength were 76.04 ft.-1bs in right knee 75.45 ft.-lbs in left knee, 78.42 ft.-1bs in dominent hand side leg 73.84 ft.-1bs in non-dominent hand side leg, and 82.52 ft.-1bs in dominent leg 71.93 ft.-lbs in non-dominent leg. 2. Sex difference of extensor strength were 95.13 ft.-lbs in male 55.98 ft.-1bs in female, and that of flexor strength were 54.90 ft.-1bs in male 33.68 ft.-1bs in female. 3. Mean of position angle of maximal torque were between 58° and 65° for extensors, 35° and 45° for flexors. 4. Mean of total range of motion at working isokinetically with 60°/sec speed was 99°. 5. Mean values of extensor power were 54.43 ft.-1bs in male 30.63 ft.-lbs in female, and that of flexor power were 35.99 ft.-1bs in male 22.42 ft.-1bs in female. 6. Strength and power decreased as ages getting old, and there was significant diminish between 4th decade and 5th decade. 7. Power endurance had more difference when it was compared with occupation. Mean value of power endurance was between 12 times and 18 times.

The alar cartilage malposition is defined as any displacement of lateral crura from the usual parallel alignment with nostril rims. It has several characteristics including parentheses deformity, notches in alar rims, flat nasal tip, square basal perimeter. It tends to be misdiagnosed as cartilaginous hump or bulbous tip because of its longitudinally prominent lobule. But, exact diagnosis can be easily attained with careful examination and recognition in the clinical diagnosis of bulbous or ambiguous tips. It is confirmed by the resistless collapse of lateral alar rim when light compression is applied by cotton stick. Its incorrect diagnosis can bring about inappropriate tip graft, soft tissue resection, rasping, humpectomy and secondary nasal deformity may develope as a result. Authors performed open approach followed by meticulous dissection of displaced alar cartilages. Each medial portion, corresponding to the cephalic portion of normal lateral crus, was resected. Then, each lateral crus was symmetrically rotated in the infero-lateral direction along the axis of the medial crura. If needed, autocartilage on-lay graft and dorsal augmentation were done for optimal aesthetic result. We believe accurate evaluation of the anatomical variation should be checked out preoperatively and recommend out method for the effective correction of unusual bulbous or broad tips.

4.Correction of Blunt Nasal Tip with "Contour Tip Gragt" and Alar Cartilage Modification.
Journal of the Korean Society of Plastic and Reconstructive Surgeons 2000;27(6):647-652
The aim of aesthetic rhinoplasty is to produce harmonious contour of the nasal tip as well as to provide dorsal augmentation. The nasal tip should look definite but not too pointed or artificial. Natural contour is most desirable. Among the patients(n = 140) who had augmentation rhinoplasty between 1995 to 1999, 107 patients were classified to have blunt tips. The cases who have other types of tip deformities were excluded. In this study, we present our tip plasty technique for the correction of blunt tips. The blunt tip deformities were divided into bulbous tip(n = 82) and broad tip(n = 25). As for the operation, different tip thinning procedures were done according to this classification. Then dorsal augmentation with silastic implant was performed. Authors used "Contour Tip Graft" technique to produce aesthetic oriental nasal tip. This technique made use of the graft of stacked autogenous cartilages with small pieces of diced cartilage around it. The stacked cartilages were for tip projection and surrounding pieces for natural contour. This method can yield more natural appearance of the tip and lobule. Our tip plasty technique combined with dorsal augmentation is very useful and effective procedure in the correction of blunt tip.

PURPOSE: To analyze the clinical characteristics and the prognosis of asymmetric retinopathy of prematurity (ROP). METHODS: We performed retrospective chart review and identified 47 patients with asymmetric ROP. Asymmetric ROP was defined as the acute ROP with definite difference between the two eyes in one of the parameters; stage, zone, plus sign or extraretinal fibrovascular proliferation (EFP) extent. The clinical characteristics and refractive error, fundus status, and visual prognosis were analyzed. RESULTS: Unilateral ROP cases were nine out of the 47 (19.1%) asymmetric ROP cases. There were more patients with small difference between the two eyes in acute ROP stage than the patients with large difference, and the larger gestational age and birthweight were related to the larger difference in acute ROP stage. Treatment was necessary in 63.8% of the severe eyes and 23.4% of the mild eyes. The refractive status was not different between the two eyes at 6-month and 3-year of age, however, there were more myopia (more than 3 diopter) in the severe eyes at 3-year of age. The anatomically unfavorable outcome was found in 4 eyes and poor fixation in 3 eyes, which were found only in the severe eyes. The best corrected visual acuity at final visit was poorer in the severe eyes than in the mild eyes. CONCLUSIONS: Among the asymmetric ROP cases, the severe eyes needed more treatment and had poorer visual prognosis than the mild eyes. Unilateral ROP could be found in some cases.

Anesthegiologists commonly use arterial cannulation for both close blood pressure monitoring and repeated blood sampling for gas analysis. Radial artery cannulation is generally thought of as a safe and uncomplicated procedure, however, some possible complications have been reported. These include bleeding, hematoma, infection, pseudoaneurysm and thromboembolism, which do not usually result in any serious clinical problems. Although it is not common, thromboembolism could be serious because it can lead to digital ischemia and necrosis. We report here a case of finger necrosis following radial artery cannulation in a patient who underwent radical hysterectomy under general anesthesia.

Dengue fever is an acute febrile disease that is caused by a mosquito-borne flavivirus. It has become a major infectious disease threat in tropical and subtropical areas. In Korea, travel-associated dengue fever is increasing. Thirty-five Koreans went to Sri Lanka to do volunteer activities. Eight of the volunteers developed fever, myalgia, and rash; they were diagnosed with dengue fever. Two patients had macular hemorrhages and edema with no ophthalmic symptoms. The maculopathy caused by the dengue fever improved without specific treatment.

Archives of Plastic Surgery 2013;40(3):173-180
As microvascular techniques continue to improve, perforator flap free tissue transfer is now the gold standard for autologous breast reconstruction. Various options are available for breast reconstruction with autologous tissue. These include the free transverse rectus abdominis myocutaneous (TRAM) flap, deep inferior epigastric perforator flap, superficial inferior epigastric artery flap, superior gluteal artery perforator flap, and transverse/vertical upper gracilis flap. In addition, pedicled flaps can be very successful in the right hands and the right patient, such as the pedicled TRAM flap, latissimus dorsi flap, and thoracodorsal artery perforator. Each flap comes with its own advantages and disadvantages related to tissue properties and donor-site morbidity. Currently, the problem is how to determine the most appropriate flap for a particular patient among those potential candidates. Based on a thorough review of the literature and accumulated experiences in the author's institution, this article provides a logical approach to autologous breast reconstruction. The algorithms presented here can be helpful to customize breast reconstruction to individual patient needs.

Total tongue resection result in severe speech problem, swallowing difficulty and life threatening aspiration. When a total glossectomy is performed, the functional recovery of swallowing, articulation, and airway protection are important for maintaining life quality of the patient. To achieve good functional results, First, the donor tissue should be bulky. Second, the tissue should be pliable and capable of movement. Third, the neotongue should be innervated by anastomosis to the hypoglossal nerve. Innervated latissimus dorsi free flap satisfies the above conditions. The authors performed two immediate total tongue reconstruction using a innervated latissimus dorsi myocutaneous free flap in which the thoracodorsal nerve was anastomosed to the hypoglossal nerve. Decanulation was performed on the 15th and 20th day respectively after the operation. The oral intake of pureed diet was possible in both patients without aspiration. After 3 months, it was confirmed in videofluoroscopic study that the neotongue was able to contact with the palate effectively. And the articulation was satisfactory. Considering speech and feeding rehabilitation, innervated latissimus dorsi flap can be more valuable method of tongue reconstruction than any other methods and we recommend it for better life quality of the patient.

Cardiovascular malformations, such as bicuspid aortic valve and coarctation of the aorta, are more prevalent in patients with Turner syndrome than in the general population. Here, we describe the case of a 35-year-old female with Turner syndrome who was admitted to our hospital with a fever caused by infective endocarditis. Aortic coarctation was diagnosed using computed tomography. The patient was treated with antibiotics and a stent was then implanted. Endovascular therapy using stents is a safe and effective treatment option for aortic coarctation in patients with Turner syndrome.
