Despite the continually improving results of total knee arthroplasty, infection remains the most debilitating complication. The treatments of infected total knee arthroplasty were variable, but initially we removed infected implants and inserted antibiotic containing cemented spacer. Postoperatively, patients were mobilized in a 30 knee flexion state and treated with parenteral antibiotics. After control of infection was clinically and radiologically determined, we inserted PCL substitute total knee prosthesis. Five days postoperatively, patient began touch down standing exercise. We observed two cases in whom infected total knee arthroplasty had been salvaged successfully with two-stage implantation using cement spacers containing antibiotics.

Dermoid cysts develop from sequestration of epithelium along lines of embryonic fusion.The most common locations are the lateral third of the eyebrows, nose, and scalp. These cysts are located in the subcutis; they are often adherent to periosteum, and may invade or erode underlying bane. A 34-year-old female presented with a solitary, skin colored, dome-shaped, child fistsized, subcutaneous mass on her right occiput. At operation, keratinous material was discharged and tufts of hair projected from opening of the cyst wall.The base of the cyst was firmly adherent to periosteum and diffuse depression with focal deep erosions of the outer table of skull was found.

OBJECTIVES: The aim of this study was to evaluate the differences in patients with positional dependent sleep apnea according to their non-supine apnea-hypopnea index (AHI, > or =5 vs. <5). METHODS: 92 patients with positional sleep apnea were evaluated. The patients were divided into two groups : group I was non-supine AHI having > or =5 ; group II was non-supine AHI having less than 5. Statistical analysis was performed to find the difference between two groups. RESULTS: In 92 patients, the number of group I patients was 11 (12%) and the number of group II patients was 81 (88%). In the severe AHI group, percentage of group I was dominated (70%) and showing a significant difference compared with the mild and moderate AHI groups (p<.05). In the severe body mass index (BMI) group, percentage of group I was dominated (54.5%) and showing a significant difference compared with of the mild and moderate BMI groups (p<.05). The percentage of group I was significantly higher than group II (p<.05) in the AHI, supine AHI, non-supine AHI and snore time. CONCLUSIONS: In patients with positional sleep apnea, severe OSA and high BMI are more common in patients with non-supine AHI> or =5 than non-supine AHI<5.

Leiomyorrw is the mest cunmon in the uterine hunor. Smooth muscle tumors of the female genital taact arise mostly from the uterine myometrium and only rarely from the broad ligament. We experienced a cases of huge leiomyoma of the broad ligarnent with secondary cystic degeneration. In the respect of rarity, we report this case with a brief review.

Background: This study aimed at investigating the meal regularity, health, and oral health habits of single Korean households to understand the impact of these factors on the risk of metabolic syndrome, in addition to preventing and managing metabolic syndrome. Methods: Using raw data from the 8th Korea National Health and Nutrition Examination Survey (2019), 274 study subjects, aged 19 to 64, were selected primarily from single adult households. Complex sample statistical analysis was performed using the Predictive Analytics Software Statistics ver. 18.0 program. Results: Regarding the meal regularity in single-person households in Korea, the younger group outperformed the middle-aged group, and those who drank more than once a month performed better than those who drank less than once a month. In terms of oral health, regardless of the age and the income level, participants who ate three meals a day had a higher rate of speech problems and chewing difficulties than those who ate irregularly or regularly on a regular day. Factors influencing the risk of developing metabolic syndrome were age, speech problems, and frequency of toothbrushing. Compared to the younger group, there were 0.361 times more people in the middle-aged group; and compared to those without speech problems, there were 1.161 more people with speech problem. Compared to those who tooth brushed more than four times a day, there were 1.284 more people who tooth brushed 2 to 3 times a day and there were 5.673 times more people who tooth brushed less than once. Conclusion Based on the study results, it is necessary to implement a program that can plan and apply customized management measures and prevent metabolic syndrome by improving and correcting the health and oral health behaviors of single-person households in Korea. Therefore, active mediation measures, such as support and publicity at the local or national level, should be planned.

BACKGROUND: During normal wound healing the formation of scars and fibrous tissue occurs, which consists largely of collagen fibril, but excessive fibrosis and scar formation become clinical problems. Collagen remodelling during scar formation is dependent on both continued collagen synthesis and collagen catabolism. Halofuginone, a plant alkaloid, is known to inhibit collagen type I synthesis at the transcriptional level. OBJECTIVE: The purposes of this study were to investigate the effects of topical application of halofuginone on the healing of wounds. METHOD: Topical solutions containing halofuginone of variable concentrations were applied on the full-thickness excisional wounds of hairless mice and 0.1% halofuginone ointments applied on the suture site of rats and the normal skin of hairless mice daily. In addition, we performed a one-time intradermal injection of 0.1% halofuginone solution on the normal skin of the hairless mice. We examined the collagen content of the skin of hairless mice and rats treated with halofuginone solutions and ointments during the healing process by performing hematoxylin-eosin and Masson's trichrome stains. We assessed, from time to time, the change in the full-thickness excisional wound size of hairless mice treated with halofuginone solutions of variable concentrations during the healing process and observed clinically the healing process of hairless mice with the full-thickness excisional wound. RESULT: 1. The wound size after daily application of 0.001% and 0.1% halofuginone solutions on the full-thickness excisional wounds of hairless mice decreased more slowly in comparison with the control group (p < 0.05).

We report a case of cutaneous sarcoidosis which occurred in a 32-year-old female who had, in addition to some cutaneous nodules, recently developed an acute spontaneous erythematous area of induration in old scars on her forehead and lower lip. Histopathologic findings revealed well-demarcated islands of epitheloid cells with a few giant, cells. In addition, slight admixture of lyrnphoid cells with present. at the margins of the epitheloid cell granulomas. Complete regression of the skin lesions was obtained with systemic steroid therapy without recurrence for some 8 months.

Malignant eccrine poroma, or eccrine porocarcinoma, is a rare malignant cutaneous appendageal tumor arising from the intraepidermal eccrine sweat duct(acrosyringium), and usually develops ia an eccrine poroma of long-standing. We report a case of malignant eccrine poroma on the left buttock in a 72 year-old female. She was presented with a slightly pruritic, well-defined, reddish, firm, 4.5 x 4.5 x 0.7cm sized, protruding, ulcerated tumor. Histopathological examination revealed well-defined tumor cell nests in the epidermis and dermis. The tumor nests consisted of areas of eccrine poroma cells with benign appearance adjoining areas of anaplastic cells. Duct-like structures were observed within the tumor nests and showed a PAS-positive, diastase-resistant reaction. On immunohistochemical staining, the tumor cells were, positive for EMA, and most of tumor cells were negative but the duct-like structures were positive for CEA. She was treated with surgical excision. During the three year follow up period after excision, there was no recurrence.
