We had a female patient with soft tissue tumor involving large portion of Achilles tendon. After resection of tumor, Achilles tendon was reconstructed using an allogenic human fascia lata manufactured by Pfrimmer-Viggo. EMG findings on postoperative 8 months show marked improvement of function of medial and lateral gastrocnemius muscles. Biopsy specimen of fascia lata allograft, which was acquired during TAL 8 months postoperatively, shows myxoid degeneration, a few lymphocytic infiltration and some foreign body giant cells. Functional, histologic and EMG findings suggest that human fascia lata allograft could be used to bridge defect of Achilles tendon being resected during tumor surgery.

OBJECTIVES: This study was designed to evaluate bethanechol's efficacy in urinary difficulty, constipation, dry mouth and blurred vision and to evaluate the bethanechol's effect on psychopathology. METHODS: Thirty-two schizophrenic patients who have been treated with antipsychotics and the total score of anticholinergic side effect of 'Rating scale for side effect (no symptom ; 0, severe ; 3)' is above 5 were assigned to three group(controlled group, bethanechol 30 mg/day group, 60 mg/day group). These patients were entered on 6 weeks open trial. Anticholinergic side effects were assessed by 'Rating scale for side effect' and psychopathology by BPRS at base, 2nd week & 4th week. After 4weeks administration of bethanechol, 30 mg/day group was increase to 60 mg/day and 60 mg/day group was decreased to 30 mg/day for 2 weeks for evaluation of dose difference. And then anticholinergic side effects were reassessed at 6th week. RESULTS: There were significant correlations between blurred vision and age. There were no significant improvement of anticholinergic side effect in placebo group but significant improvement of urinary difficulty and dry mouth in 30 mg/day group and significant improvement of urinary difficulty, constipation and dry mouth in 60 mg/day group at 4th week evaluation. In the case dose up(bethanechol 30 mg/day to 60 mg/day) for 2 weeks, dry mouth was more improved. In the case of dose down (60 mg/day to 30 mg/day), the improvements of urinary difficulty and dry mouth were sustained but constipation was aggravated. There were no BPRS changes by bethanechol administration. CONCLUSION: These findings suggest that more than 30 mg/day of bethanechol made improvements in urinary difficulty, constipation, dry mouth, when the total score of Anticholinergic side effect of 'Rating scale for side effect (no symptom ; 0, severe ; 3)' is above 5, although 60 mg/day of bethanechol was more effective than 30 mg/day. Moreover bethanechol administration does not influence psychopathology.

BACKGROUND: Recruitment and development of multiple follicles in response to gonadotropin stimulation are the key factors leading to successful treatment by assisted reproductive technologies. Prediction of ovarian responses prior to stimulation is useful in counselling and helpful in adjusting the dosage of gonadotropin to individual patients. OBJECTIVE: To evaluate the number of antral follicles of both ovaries as a predictor of outcome of assisted reproductive technologies. METHODS: Data were collected by a retrospective analysis. A total of 56 consecutive infertile women were undergoing the first cycle using a standard regimen of ovarian stimulation from July, 2000 to June, 2001. Basal FSH, LH, prolactin, and estradiol concentration were measured. The number of follicles (2-5 mm) were recorded. RESULTS: In women with fewer antral follicles, the number of retrieved eggs was significantly decreased and increased the duration and dosage of human menopausal gonadotropin, but pregnancy rate was similar to those with a higher number of antral follicles. CONCLUSION: It is suggested that the total antral follicle number is sensitive ultrasound parameter in predicting the ovarian response.

BACKGROUND: Studying immigrants may have the potential to explore how cultural and environmental changes affect the internet game play patterns of individuals in the two countries. We planned to compare risk and preventive factors for Internet Gaming Disorder (IGD) between Korean adolescents in Korea and immigrant Koreans in the US. METHODS: Ninety-four Koreans and 133 immigrant Koreans were recruited. Independent factors consisted of five domains including demographic data, physical activity, academic, art, and music activities, psychological factors, and game and media play. The dependent variable in the current study was the high-risk group of IGD, which was assessed with Young’s Internet Addiction Scale scores. To determine the protective and risk factors for IGD, we performed a multiple logistic regression analysis using the high-risk group as the dependent variable. RESULTS: Five domains affected the risk for IGD in Korean and immigrant Korean groups. Vigorous physical activity was the strongest protective factor for IGD in the Korean group, while media activity was the strongest protective factor for IGD in immigrant Koreans in the US. CONCLUSION: The results indicate that internet gaming problems might be affected by environmental factors and it is recommended that gaming activity is substituted with physical activity, extracurricular classes, books, and music.

BACKGROUND: The pathogenesis of psoriasis may involve the interleukin (IL)-23 and Th17-mediated immune responses. Th17 cells secret IL-17 and IL-22, which mediates dermal inflammation and acanthosis. OBJECTIVE: As inhibitor of nuclear factor kappaB kinase-alpha (IKKalpha) has been previously identified as a primary regulator of keratinocyte differentiation and proliferation, we proposed that IL-17 and IL-22 might affect keratinocyte differentiation by changing the expression of IKKalpha. METHODS: We employed HaCaT cells maintained culture medium at a low calcium concentration (0.06 mM) and induced differentiation by switching to the high concentration (2.8 mM) media with IL-17 or IL-22, then compared the IKKalpha expression and the cell cycle. We employed reconstituted human epidermal skin (Neoderm) and mice ears for the in vivo studies. RESULTS: Elevated calcium concentration induced IKKalpha expression and terminal differentiation with cell cycle arrest in HaCaT cell cultures. Moreover, IL-17 and IL-22 treatment also induced IKKalpha in HaCaT cells and reconstituted human epidermis. IKKalpha induction was also noted, following the injection of IL-17 and IL-22 into mice ears. CONCLUSION: Although the induction of IKKalpha was accompanied by keratinocyte differentiation, IL-17 and IL-22 did not affect calcium-mediated differentiation or the cell cycle. Rather, IL-17 and IL-22 appear to contribute to the inflammation occurring via the induction of IKKalpha from keratinocytes or skin layers.

BACKGROUND: There is a need to prepare an adequate blood supply because of the imbalance between the blood supply and demand and the advent of an aging society. This paper presents the basic data for the blood supply and demand through an estimation of the blood donation and blood usage over the next ten years. METHODS: Data analysis was carried out using time-series methods. The data for the monthly blood donation from the Korean Red Cross from 1992 to 2004 was used to estimate the blood donation, and data of the blood supply from the Korean Red Cross and hospitals from 2000 to 2004 for the estimation of the blood supply for transfusion. In order to overcome the limits of the time-series methods, one prospect excluding the data from the year 2004 and the other prospect including the data from the year 2004 were analyzed simultaneously. RESULTS: According to the analysis performed with data from the year 2004 excluded, blood donation rate is expected to decrease to 2.5% in 2015 and the total blood demand (1,435,903 units), which is composed of RBC and single donor platelet, is expected to exceed the total blood donation (1,408,244 donors) by 2015. According to the analysis performed with the data from the year 2004 included, the blood donation rate is expected to decrease to 1.3% in 2015 and the total blood demand (1,760,219 units) is expected to exceed the total blood donation (1,639,042 donors) in 2009. CONCLUSION: A shortage of blood supply is expected to occur during the next ten years. In order to eliminate this blood shortage, a national data management system for blood collection and usage will be needed. In addition, adequate donor resources as well as a monitoring system will be needed to improve the efficiency of blood usage.

PURPOSE: In order to prevent tuberculosis transmission early, it is important to diagnose and treat tuberculosis infection by investigating people who have contact with patients with active tuberculosis. METHODS: From July 2014 to June 2017, the intrafamilial childhood contacts of the patients who were diagnosed with active tuberculosis at Chungnam National University Hospital were investigated for the presence of tuberculosis infection. We also retrospectively analyzed the treatment status of children treated with latent tuberculosis infection (LTBI) during the same period. RESULTS: Among the 269 children who had intrafamilial contact with active tuberculosis patient, 20 (7.4%) did not receive any screening. At the first screening, one (0.4%) was diagnosed with pulmonary tuberculosis, seven (2.8%) had a previous history of tuberculosis infection, and 42 patients (16.9%) were diagnosed with LTBI. At the second screening, 29 patients (11.6%) were diagnosed with LTBI, and 61 patients did not finish the investigation. Only 188 (69.9%) out of 269 patients completed the investigation. Ninety patients received treatment for LTBI and 83 patients (92.2%) completed the treatment, of which 18 patients had side effects such as rash, fatigue, and gastrointestinal symptoms. However, there were no serious side effects requiring treatment discontinuation. CONCLUSIONS: The completion rate of childhood tuberculosis contact investigation was low, but the completion rate of LTBI treatment was high in children without serious side effects. In order to prevent and manage the spread of tuberculosis, active private-public partnership efforts and education of the patient and guardian are needed.

Purpose: This study was conducted to identify the types of perception toward quarantine measures at hospitals or community treatment centers among patients infected with COVID-19. Methods: This study applied Q-methodology. Two hundred and nineteen Q populations were constructed based on related literature and in-depth interviews with 5 adults infected with COVID-19 and who experienced quarantine and hospitalization. Interviews were performed from November 14 to 29, 2020. A total of 45 Q samples were extracted and Q sorting was performed using a 9-point scale for 30 adult subjects who experienced quarantine at hospitals and community treatment centers. The data were analyzed using the PC-QUANL program. Results: The perception of subjects toward quarantine measures was classified into the following six types: ‘passive acceptance’, ‘social stigma perception’, ‘appreciation of daily life through awareness of the realities of illness’, ‘why me?’, ‘fearful perception’, and ‘positive meaning’. Conclusion The perception of quarantine measure among patients with COVID-19 is identified as six types with positive and negative emotional characteristics. This result will contribute to the development of individualized strategies to address psychosocial health problems among patients with infectious diseases.

PURPOSE: This study analyzed a small outbreak of measles at a single hospital located in northern Gyeonggi-do in 2013. METHODS: We reviewed the medical records of measles patients at The Catholic University of Korea Uijeongbu St. Mary's Hospital from August to October, 2013. RESULTS: Fifteen children were confirmed to have measles by RT-PCR and serum IgM test; 1 neonate, 11 infants, and 3 toddlers. None of the patients had received Measles-Mumps-Rubella vaccination. All patients showed B3 type in viral genotyping. Nine children (60%) had been exposed to measles during treatment for other diseases in the pediatric ward. Incubation period was between 8 and 15 days. Fever started at a median 10 days after exposure and persisted for a median of 8 days. Rash showed at a median 13 days after exposure. Respiratory complications were observed in 40% of patients. Diarrhea developed in 53% of patients. CONCLUSION: Although measles has been well-controlled due to the high rate of vaccination coverage, it is possible to have an outbreak at any given time, especially in infants. We must learn from this outbreak, and remain fully aware of the possibility of reemergence and provide proper management, including vaccination or immune globulin administration, to infants exposed to measles. Reevaluation of serum IgG titer of neonates, infants, and pregnant women may be the first step to prevent further outbreaks.
