Supervised weekly fluoride mouthrinsing(FMR) program with 0.2 percent neutral sodium fluroide solution has been implemented at primary schools in Pusan, Korea since 1995 to prevent the prevalent dental caries. Children of sixth grade in 2000 who had joined the weekly FMR program at four primary school in Pusan with a 0.2 percent sodium fluoride solution for five years from first grade in 1995 to fifth grade in 1999 were selected as experimental group. Children of sixth grade in 2000 who had not joined the FMR program until sixth grade and had not drunk fluoridated pulic water at two primary schools in the Bukgu(Norhtern) District of Ulsan were selected as control group. Samples were 295 in FMR group and 312 in control group. To estimate caries preventive effect, epidemiologic dental survey was performed at the schools of FMR and control group in 2000 for 11-year-old children. The surveyed data were analyzed with SPSS statistical package. The obtained results were as follws. 1. Children who experienced caries on permanent teeth were 71.2% in FMR group and 83.3% in control group. 12.1% of DMF rate decreased in FMR group compared to control group. 2. The DMFT scores were 2.68 in FMR group and 3.29 in control group. The difference of DMFT scores was 0.61 between fluoride mouthrinsing group. The caries reduction rate from 5-year FMR program was calculated as 18.5% by the difference of DMFT scores between FMR group and control group. 3. The DMFS scores were 4.04 in FMR group and 5.05 in control group. The difference of DMFS scores was 1.01 between FMR group and control group. The caries reduction rate from 5-year FMR program was calculated as 20.0% by the difference of DMFS scores between FMR group and control group. 4. Significant Caries Index of permanent teeth was 5.46 in FMR group and 6.02 in control group. 5. We suggest that fluoride mouthrinsing program should be developed to all primary schools to prevent dental caries.

Fluoride-containing toothpaste is one of useful tools to apply fluoride for prevention of dental caries. The purpose of this study was to survey the user rate of fluoride-containing toothpaste at home for the oral health education of the use of fluoride-containing toothpaste. Questionnaires about the use of fluoride-containing toothpaste were distributed to the children of primary middle schools and adults in Buk-gu(Northern District) of Ulsan Metropolitan City, Korea. Collected questionnaires from 374 primary school children, 505 middle school children and 161 adults were analyzed. All collected date were analyzed using the SPSS program. The obtained results were as follows; 1. 36 brands of toothpaste were being used at home. 29 brands contained fluoride and 9 brands were the toothpaste for children. 2. Among total respondents, 97.4% used the fluoride-containing toothpaste. 3. The user rate of fluoride-containing toothpaste were 97.9% among elementary school children, 97.2% among middle school children and 96.9% among adults. There was no significant difference among groups. 4. Among respondents using fluoride-containing toothpaste, SMFP-containing toothpaste were used by 90.9% of subjects, NaF;9.9%, combination of SMFP and NaF;0.1%. 5. Only 33.0% of respondents correctly knew whether they really used the fluoride-containing toothpaste or not.

Inspection of nails suggest an underlying systemic disease. Clubbing nail is mainly associated with pulmonary, neoplastic, and gastrointestinal diseases. It is characterized by thickening of the soft tissue beneath the proximal nail plate. It can be diagnosed with positive Lovibond angle and Schamroth’s sign. Lovibond angle is the angle between the proximal nail fold and the nail, which is considered pathologic when exceeding 180°. Schamroth’s sign is disappearance of the diamond shape which is normally made when the dorsal surfaces of two nails are attached. When it is observed, more exams are needed, based on associated symptoms with screening of malignancy. Especially, chest radiography should be performed to exclude pulmonary disease which is the most common cause of clubbing nail. A 79-year-old man presented with 1-year history of thickening on both nails. He was diagnosed as onychomycosis and treated with topical antifungal agents for 1 year at a local clinic without improvement. He had 25-pack-years of smoking history. On physical examination, enlargement of the ends of the fingers and toes and a downward sloping of the nails were observed with positive Lovibond angle and Schamroth’s sign. KOH smear for fungus was negative. He didn’t complain any other symptoms. Chest radiography showed interstitial lung disease on both lungs without active inflammation. We consulted to pulmonary department, but the patient lost to follow-up.
Hailey-hailey disease masquerading as erythrasma

Hailey-Hailey disease (HHD) is a rare autosomal dominant disease characterized by crusted weeping erosions, vesiculopustules, and vegetating plaques with fissures. HHD affects the sites of friction such as the neckline, axilla, or groins. Itch, pain, and malodor are common complaints. HHD is exacerbated after triggers such as skin UV radiation, skin infection, physical trauma, excessive sweating. HHD may be difficult to distinguish from other intertriginous diseases. In particular, secondary bacterial or fungal infections are common on the affected areas, it is difficult to differentiate from infectious diseases such as erythrasma and candidiasis. A 50-year-old man presented with painful erythematous scaly patches with yellowish discharge on both thighs and scrotum for 7 months. As a driver, the patient was seated for a long time and his inguinal area was damped. Application of topical treatment showed mild effect, but it exacerbated because of tight clothing and his occupational status. Previously, he was diagnosed as erythrasma and treated with systemic and topical antibiotics, topical antifungals, and topical corticosteroids. Histopathologic examination on inguinal area showed suprabasilar clefting with acantholytic cells consistent with HHD. Direct immunofluorescence for IgG was negative. The patient was treated with oral minocycline. HHD should be considered in patients with recurrent flares of intertriginous lesions.

Hidrocanthoma simplex(HAS) is a rare benign intraepidermal neoplasm arising from eccrine duct. Clinically, it appears as brownish or verrucous plaque on the lower extremities. Histologically, HAS can exhibit intraepidermal cell nests which are called “Borst-Jadassohn phenomenon”. It could be observed in the HAS, clonal seborrheic keratosis (SK), Bowen’s disease and actinic keratosis. An 86-year-old female presented with several decades history of huge brown, verrucous plaque on the right buttock. At initial biopsy, intraepidermal clonal expansion of polygonal basaloid cells were observed within acanthotic epidermis. She was diagnosed as clonal SK, and was removed by CO2 laser ablation. After 3 months, she returned with polypoid grouped papules on the previously treated area. Histologic examination showed intraepidermal proliferation of small to medium-sized polygonal basaloid cells as well as large cells with abundant clear cytoplasm. Atypical cells with large, hyperchromatic nuclei were observed. There was a component of eccrine syringofibroadenoma which is characterized by thin, anastomosing cords of epithelial networks with duct formation extending from the base of the tumor. Tumor cells were stained with EMA and PAS. Final diagnosis was HAS combined with eccrine poroma, eccrine syringofibroadenoma and focal malignant changes. Herein we report a case showing natural history of eccrine tumor from HAS to malignant changes over time.
