The purpose of this study was to investigate effects of nutrition education program and pamphlet for the lower grades elementary students focused on individual daily needed food exchange units using Food Exchange System. Program consisted of four lessons (40 min/lesson), "5 major nutrients & function", "6 food group and sources", "daily needed food exchange units for normal body weight", and "smart snack choice and exercise". Pamphlet as activity book was developed for the program. The subjects were 3rd grade elementary students (educated group, 31 vs. non-educated group, 31). Educated group were lessoned as group and/or individual. We examined the differences in nutrition knowledge, dietary attitudes, dietary intakes and satisfaction of the program and pamphlet. In educated group, there were positive improvements on nutrition knowledge score "function and foods of 5 nutrients" and on dietary attitudes "type of breakfast and snacks". In the evaluation of dietary intakes according to KDRI, there were positive improvements on intakes level of riboflavin, vit. C, folate, Ca, P, Fe and Zn in educated group. In satisfaction with the program and pamphlet, contents, font size, visual, figure, difficulty and program curriculum were over 2.90/3.0. It showed that the developed nutrition education program and pamphlet focused on individual daily needed food exchange units using Food Exchange System improved nutrition knowledge, dietary attitudes and nutrients intake level in the lower grades elementary students.

Intersphincteric resection (ISR) is the ultimate sphincter saving procedure for low rectal cancer. Hemorrhoids are a common benign condition. We present and discuss a case of ISR which developed painful edematous hemorrhoids after ISR. A 62-year-old female with low rectal cancer received neoadjuvant chemoradiotherapy with successful down staging of tumor before undergoing robot assisted ISR with coloanal hand-sewn anastomosis. She had pre-existing external hemorrhoids which were not excised. She developed painful and edematous external hemorrhoids 4 days after surgery. These were treated conservatively before discharge. Many colorectal surgeons performing ISR have experienced similar situations in their patients, but none have reported on this phenomenon. We discuss the possible factors that may contribute to this situation. A possible solution is prophylactic excision of the hemorrhoids during coloanal anastomosis. Painful hemorrhoids may occur after ISR and if managed conservatively, the outcome is skin tags.

BACKGROUND: Famciclovir and valacyclovir are antiviral agents commonly used to treat herpes zoster. These medications not only reduce the time to complete cessation of zoster-associated pain, but also aid in the healing of the herpes zoster skin lesions. However, only few studies have compared these antiviral agents. OBJECTIVE: We conducted a randomized clinical trial to evaluate the extent of pain relief and wound healing, and the rate of postherpetic neuralgia associated with these drugs during 4 weeks of treatment. METHODS: The study included 69 immunocompetent adult inpatients diagnosed with herpes zoster randomly divided into 2 groups based on the antiviral agent administered. Patient age, date of visit from rash onset, and rash severity at baseline were recorded. Famciclovir or valacyclovir were administered orally for 7 days. Patients reported pain levels through a visual analog scale (VAS) score, and pain durations were assessed on days 1, 3, and 7, and at weeks 2, 3, and 4. Crust formation and reepithelialization times of skin lesions were also recorded. RESULTS: VAS scores, pain durations, ratios of patients undergoing postherpetic neuralgia, and skin lesion healing rates did not differ significantly between the 2 groups. However, rash severity independently correlated with the extent of pain experienced. CONCLUSION: Famciclovir and valacyclovir are comparable to each other in resolving zoster-associated pain, postherpetic neuralgia, and zoster wound healing. Early antiviral treatment before expansion of the skin lesion would be helpful for rapid relief of herpes zoster pain.

BACKGROUND: The late results of repair of tetralogy of Fallot(TOF) are favorable in most patients. Some portion of the patients with tetralogy, however, require reoperation for residual lesions or result in late death. The outcome of patients after tetralogy repair performed during the past 13 years was studied, with an emphasis on postrepair survival and problems including reoperations. MATERIAL AND METHOD: A retrospective review of clinical, echocardiographic and catheterization data was performed in 569 of 775 patients with TOF who underwent corrective repair between 1983 and 1995 at Sejong General Hospital, Buchon, Korea. RESULT: Of 28(4.9%) early deaths(defined as 30 days postrepair), 12 deaths(42.9%) were <1 year of age, with an operative mortality of 15.4%. The surviving 541 patients(age 2.8 months to 43.4 years, median 23 months) have been followed up from 1 month to 12.6 years(median 35 months) postoperatively. Most patients were in good functional class and had normal right ventricular(RV) function. Postrepair results were compared between the transatrial-transpulmonary approach and the conventional right ventriculotomy. The former technique provided a lesser incidence of significant pulmonary regurgitation(p<0.001) and alesser degree of RV dysfunction(p<0.05) compared with those in the latter. There were 10(1.8%) late deaths during the follow-up period and 6 of the deaths were directly related to reoperation or ventricular dysfunction. The 10-year actuarial survival rate was 96.7%. There were 44 reoperations(8.1%) in 39 patients(7.2%), with an operative mortality of 10.3%. The main indications or reoperation included residual ventricular septal defect(VSD) (n=6), pulmonary stenosis(PS) (n=11), VSD with PS(n=17), pulmonary regurgitation(n=7), and tricuspid regurgitation(n=2). The 5- and 10-year freedom from reoperation were 89.4% and 76.1%, respectively. CONCLUSION: Although the majority of patients with repaired TOF are clinically well, with a high rate of survival, approximately 7% of patients have residual lesions that require surgical therapy. Therefore, the timely and meticulous corrective repair is mandatory to avoid reoperation, and continued close surveillance is also needed for the early detection of residual problems.

OBJECTIVE: To evaluate the efficacy and safety of radiofrequency ablation (RFA) for low-risk papillary thyroid microcarcinoma (PTMC) in a large population.MATERIALS AND METHODS: Cases of 152 biopsy-proven PTMCs from 133 patients who had undergone RFA for PTMC between May 2008 and January 2017 were included in this study. All patients were either of high surgical risk or refused to undergo surgery. They were followed up for at least 6 months after initial RFA. Ultrasonography (US) and computed tomography were performed to evaluate the PTMC and the presence of neck metastasis before treatment. RFA was conducted using an internally cooled thyroid-dedicated electrode system. Follow-up US was performed at 1 week, and 2, 6, and 12 months, after the initial RFA, and then at every 6–12 months. We evaluated serial changes of ablated tumors, newly developed cancers, lymph node (LN) or distant metastasis and complications.RESULTS: Complete disappearance was found in 91.4% (139/152) of ablated tumors. Among the 13 tumors in patients who did not show complete disappearance, no tumor displayed any regrowth of the residual ablated lesion during the follow-up period. The mean follow-up period was 39 months. During the follow-up period, there were no local recurrence, no LN or distant metastasis, and no newly developed thyroid cancers. No patients were referred to surgery. The overall complication rate was 3% (4/133) of patients, including one voice change. There were no life-threatening complications or procedure-related deaths.CONCLUSION: Our results suggest that RFA is an effective and safe option for treating low-risk PTMC patients who are of high surgical risk or refuse surgery.

PURPOSE: The early detection of breast cancer by screening mammography is important to reduce breast cancer mortality rate. The purpose of this study was to investigate the characteristics of breast cancer patients detected by screening mammography. MATERIALS AND METHODS: Surgically treated 1,265 patients at Asan Medical Center from Jul. 1989 to Dec. 1997 were evaluated. Among them, 119 patients (9.4%) were detected by screening mammography. These patients were compared with clinically detected symptomatic breast cancer group. RESULTS: The characteristics of breast cancer patients detected by screening mammography were as follows: The most common finding of mammography was microcalcifications (62.2%); The less invasive or more conservative minimal and non-destructive surgical treatments such as breast conserving surgery (21.0%), simple mastectomy (8.4%), breast reconstruction (8.4%) were performed more frequently; The median tumor size of invasive cancers was 16 mm; Node-negative cancers (83.2%) were more frequent; The early breast cancer of stage 0 and I was 70.6%; DCIS (29.4%) was highly proportionated; and The 5-year overall (95.8%) and 5-year disease-free survival rate (92.0%) were significantly higher than in clinically detected symptomatic breast cancer patients. CONCLUSION: The screening mammography was significant for detecting non-palpable, early stage breast cancer. Ultrasonography was needed as an adjunct for the accurate detection in dense breast or young women. According to early detection, the 5-year survival rate was high.

Multiple trichoepithelioma is a benign adnexal neoplasm characterized by the presence of many small papules that appear predominantly on the face. Clinical improvement have been demonstrated after several treatments such as carbon dioxide laser, cryotherapy, dermabrasion, and argon laser. However, these destructive methods have various disadvantages. We report a case of multiple trichoepithelioma treated with an intralesional bleomycin injection. Fewer lesions without scars and cosmetic improvements were observed. Bleomycin is a cytotoxic antitumor antibiotic that can be injected intralesionally by transcutaneous administration and displays excellent results for treating malignancies including skin tumors. We believe that intralesional bleomycin injection is an effective treatment option for this condition, and an easy method to conduct at the outpatient clinic.
