1.A Clinical Study of Meniscal Lesions
The Journal of the Korean Orthopaedic Association 1981;16(3):546-551
We meniscectomized 27 knees with meniscal lesions for disabling symptoms after the diagnosis by clinical evaluation and arthrography from January, 1970 to May,1979. Statistical analyses were as follows: 1. Male was affected 2 times more than female. The most meniscal lesions occurred in the age group between 10 and 29 years old (67%). 2. The lateral menisci were affected 2 times than the medial. In the former, the middle segments were affected most frequently and in the latter, the posterior horns. 3. The general diagnosis of torn meniscus for the 27 knees was correct by clinical evaluation for 19(71%), by arthrography for 20 (74%) and by two methods for 24 (88%). 4. In the follow-up study, satisfactory results were obtained in. 79%.

2.Treatment of Axillary Hyperhidrosis; Manual Subdermal Excision Combined with the Tumescent Liposuction and Subcutaneous Tissue Shaver.
Annals of Dermatology 2003;15(4):139-143
BACKGROUND: Axillary osmidrosis is a distressing problem characterized by unpleasant odor, profuse sweating, and occasional wetting of clothes that may handicap those affected both socially and psychologically. A variety of surgical methods have been developed for the treatment of axillary osmidrosis. OBJECTIVE: To introduce the manual subdermal excision combined with the tumescent liposuction and subcutaneous tissue shaver for axillary osmidrosis. METHODS: Twenty-five patients with axillary osmidrosis were treated by the manual subdermal excision combined with the tumescent liposuction and subcutaneous tissue shaver. RESULTS: Twenty-one(84%) patients had good results, four(16%) fair, and none had a poor result or recurrence. Complications included one case of hematoma, two cases of partial skin necrosis. The wound complication rate was 6.0%(3/50) for the axilla and 12%(3/25) for patients. CONCLUSION: The manual subdermal excision combined with the tumescent liposuction and subcutaneous tissue shaver is effective surgical procedure for the treatment of axillary osmidrosis with a low complication rate and recurrence.

The reservoir hosts of Thelazia callipaeda were examined. The eyes of the 76 dogs raised at farm, 78 military dogs (shepherds), 96 cattle, and 105 pigs were investigated for the presence of eyeworm. Among them, six worms of T. callipaeda were collected from two dogs raised at farm (2.7%), and 188 worms from 26 shepherds (33.5%). No worms were recovered from the cattle or pigs. These results suggest that the dogs, especially the military dogs are serving as a reservoir host of T. callipaeda. in Korea.

This study is to find out changes in medical practice at a university hospital before and after covering intraocular lens (IOL) from the health insurance benefit. The coverage started on March 1, 1993 and a total of 596 cases who were discharged from July 1 to December 31, 1992 and 580 cases who were discharged from July 1 to December 31, 1993 were analyzed. Since the standard reimbursement scheme was changed from March 1, 1993, the charges for 1992 were transformed into 1993 scheme. Major findings are as follows: Average length of stay was statistically significantly decreased from 8.24 days in 1992 to 6 86 days in 1993. Charges except IOL has been statistically significantly decreased from 501,000 won in 1992 to 444,000 won in 1993. Charges for drugs and injection have been reduced. However, charge per day for them was not much different. This is due to decrease in length of stay. Charges for laboratory tests and radiologic examination were quite the same. charges which are not covered by the insurance remained the same. The revenue of the hospital was reduced as expected. However, the hospital reduced the length of stay and increase the turnover rate in order to compensate the potential loss of revenue due to the difference of reimbursement between the out-of-pocket expense and the insurance coverage. By introducing the IOL benefit in the insurance, the insured pays less, hospital generates more revenue through shortening the hospital stay, and the total medical care cost becomes less nationwidely.

Purpose:
The electronic frailty index (eFI), which is derived from electronic health records, has been recommended as screening tool for frailty due to its accessibility and ease of use. The objective of this systematic review was to identify the prevalence of frailty assessed by the eFI and its influence on health outcomes in older adults with chronic diseases.
Methods:
We searched PubMed, Embase, Web of Science, CINAHL, SCOPUS, Cochrane, Google search, and nursing journals in Korean from January 2016 to December 2022.
Results:
Twelve studies were analyzed. The eFI score, based on routine clinical data, was associated with adverse health outcomes. The most frequent outcome studied was mortality, and the eFI was associated with increased mortality in nine studies. Other outcomes studied included hospitalization, length of stay, readmission, and institutionalization in relation to hospital care usage, and cardiovascular events, stroke, GI bleeding, falls, and instrumental activities of daily life as health conditions.
Conclusion
Early identification of frailty in older adults with chronic diseases can decrease the burden of disease and adverse health outcomes. The eFI has a good discriminative capacity to identify frail older adults with chronic diseases.

Since Green et al has introduced a new technique of retrograde intramedullary nail, the use of retrograde interlocking intramedullary nails has been recommended as one of the treatment options for the distal femoral fracture. However there are some disadvantages that an arthrotomy is required for insertion and the knee joint could often be violated. Authors present a simple, arthroscopically assisted method using the retrograde intramedullary nailing for distal femoral fractures with minimal invasiveness to the knee. From March 1995 to March 1997, the retrograde intramedullary nail was used to treat 9 distal femoral fractures. Five of 9 patients were fractured at the distal shaft of the femur and others were fractured at the supracondylar region of the femur. Only one of the fractures was open injury(Gustilo-Anderson grade II). Significant concomitant knee joint injuries were revealed through the arthroscopy in 3 patients. Eight of 9 fractures healed by 5 months, but one fracture was not healed and required bone grafting. Average knee range of motion was 130. Complications included 1 nonunion and 1 hardware failure. There were no patellofemoral problems and no posttraumatic arthritis of the knee joint. This arthroscope-assisted method have some potential benefits that include decreased risk of damage to the knee joint, early evaluation and treatment of the associated knee joint injuries, and accurate placement of the nail.

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.

We clinically reviewed four patients who were suffering from aseptic meningitis combined with polio-like paralysis and performed radiological. neurological and virological studies on them. Three patients were admitted to the department of Pediatrics. Asan Medical Center from March to August 1990, and one patient was admitted to the department of Pediatrics. Kangnam General Hospital. The results were as follows; 1) During the period of study, 18 patients (10.1%)out of 178 aseptic meningitis patients also suffered from hand, foot and mouth disease, and three patients (1.69%) out of 178 patients also suffered from polio-like paralysis. 2) The age of the patients who also suffered from polio-like paralysis were eight months, 22 months, 23 months and four years old respectively. Three patients were male and one patient was female. 3) Paralysis developed three to five days after aseptic meningitis infection. 4) In two cases, Magnetic Resonance Imaging (MR) showed two small cavitary lesions that means anterior horn cell necrosis in concordant with residual paralysis. Axial T1-weighted image showed decreased signal intensity and axial T2-weighted image showed increased signal intensity. In another case 20 days after onset of illness MR was performed, the transverse myelitis showed mild swelling of cornus medullaris. Follow up MR in 2 months revealed atropic change in lower thoracic spinal cord. 5) The electromyography and nerve conduction velocity test revealed acute polyradiculoneuropathy. 6) Serologic virus study were carried out in three cases for Coxsackievirus A16 and Enterovirus 71. The Enterovirus 71 antibody titer were 1:128 in two cases and 1:64 in one case. The Coxsackievirus A16 antibody titer were less than 1:4. This study showed that the causative agents for polio-like paralysis during this period seemed to be the Enterovirus 71 infection.

A 57-year-old man presented with a tender, solitary, 0.3 cm-sized, subdermal nodule on the left periocular area for several months. He had surgery three times for recurrent primary mucinous eccrine adenocarcinoma on the right periocular area. Skin biopsy showed a tumor separated by strands of fibrous tissue and small compartments of tumor cells were surrounded by pale-staining mucin. The cluster of tumor cells contained atypical epithelial cells. The mucin stained with periodic acid-Schiff (PAS) and alcian blue at pH 2.5. Cytokeratin-7 (CK7) was positive for tumor cells, but cytokeratin-20 (CK20) and S-100 were negative. For evaluation of local metastasis, computed tomography was performed and there was no evidence of regional lymph node metastasis. The lesion was removed by local excision and the patient was under close follow up without any sign of recurrence. To our knowledge, double primary mucinous eccrine adenocarcinomas in the opposite body site has never been reported.

To date, hundreds of fungal genomes have been sequenced, and many more are underway. Recently developed cutting-edge techniques generate very large amounts of data, and the field of fungal genomics in dermatology has consequently evolved substantially. Methodological improvements have broadened the scope of large-scale ecological studies in dermatology, including biodiversity assessments and genomic identification of fungi. Here, we aimed to provide a brief introduction to bioinformatic approaches to fungal genomics in the field of dermatology. We described the history and basic concepts of fungal genomics and presented sequencing-based techniques for fungal identification, including a list of the revised taxa of dermatophytes, as determined by current phylogenetic analysis. Finally, we discussed the emerging trends in fungal genomics in dermatology, such as next-generation sequencing.
