We herein report a 4-year-old boy with infantile digital fibrornatosis developing on the distal & middle phalanx portion of the right index & ring fingers, and the middle phalanx portion of the right middle finger, which started at the age of 5 months after birth. Biopsy specimen taken from the right middle finger showed the proliferating collagen bundles and fibroblasts in the dermis and eosinophilic cytoplasmic inclusions within the fibroblasts. Although we attempted to treat tbe patient with intralesional injection of triamcinolone acetonide suspension and cryotherapy 5 times biweekly, there was no signifit effect.

Because most of the benign skin appendage tumors arise from pluripotential cells that form during adult life and possess the potentiality of differentiating in more than one direction, combinations of several tumor types can occur. We report a case of combined with eccrine poroma, clear cell hidradenoma, and syringocystadenoma papilliferum as a single tumor in a 41-year-old male who had suffered from a tumor on posterior neck for 5 years. The tumor was a relatively oval shaped pedunculated, and rubbery hard mass, measuring 3.5*3.0* 1.3cm in size. The outer surface was variegated and covered with hair. The diagnosis was confirmed by histopathological findings and surgical excision was done.

The significance of cervical erosion with benign cellular change on Papanicolaou smear has not been evaluated. A retrospective review of 430 coloscopically directed punch biopsies performed over 15 months revealed 206 cases who had a benign cellular change on cytologic smear. Of these 206 smears, 48(23%) had clear cervix without erosion, 99(48%) had mild erosion on cervix, 41(20%) had moderate cervical erosion and 18(9%) had severe cervical erosion. The false negative rate that revealed more than mild dysplasia on histologic diagnosis was 2% in patients without cervical erosion, 3% in patients with mild cervical erosion, 5 % in patients with moderate cervical erosion, and 11% in patients with severe cervical er- osion. Koilocytotic change that suggested human papilloma virus infection was 17% in each group regardless cervical erosion. In conclusion, benign cellular change on Pap smears in patients with severe cervical erosion may be associated with significant cervical cancer pathology.

This investigation was designed to categorize Angle's class III malocclusion groups through analyzing horizontal and vertical components of craniofacial skeleton in Angle's class III malocclusion. The material selected for this study consisted in standard lateral cephalogram of one hundred and fifty five children, seventy four boys and eighty one girls, aged 6 through 15 years, having Angle's class III malocclusion. On the basis of findings of this study, the following results were obtained. 1. In horizontal skeletal classifications, 16 groups were classified FMN-A-B, SE-FMN-A according to the Ba-SE-Me, Ba-SE/R. 2. The sequences that have relatively high frequency are as follow; a) Horizontal Group 1 b) Horizontal Group 3 c) Horizontal Group 5 d) Horizontal Group 9 e) Horizontal Group 4 3. In vertical skeletal classification, 8 groups were classified according to the PMV/PP, PMV/OP, PMV/MP. 4. The sequences that relatively high are as follows; a) Vertical Group 1 b) Vertical Group 3 c) Vertical Group 4 d) Vertical Group 8

OBJECTIVES: The purpose of this study is to analyse sleep habits and sleep disorders in the elderly population ased 65-84 years. METHODS: Epidemiological survey was performed at home by means of semistructured interviews in the city of Pusan, Korea. Subjects were randomly selected. The questionnaire consisted of 128 items including demographic findings, sleep habits, sleep disorders, somatic illnesses, and psychological distresses. RESULTS: (1) The mean retiring time was 10.28 h (SD1.30 h) and the mean wake-up time was 5.24 h (SD 1.33 h). The mean duration of sleep was 5.63 h (SD 1.80 h ). The subjects reported they woke up an average of 2.05 (SD 1.59) times per night. All of the above results were not related to age or gender. However, the mean frequency of difficulty in initiating/maintaining sleep was 2.2 times for men and 3.2 times for women (p<0.05). (2) The prevalence of insomnia was 57.7% and was not related to age or gender. Difficulty in initiating sleep was the most commonly reported insomnia complaint(52.4%). Early morning awakening was reported by 50.0% of patients and difficulty in maintaining sleep was reported by 45.1% of them. Worrying in bed and physical pain were strong contributing factor to insomnia. CONCLUSIONS: The results of our study showed several characteristics of sleep habits in the elderly. Sleep disorder in old age is not inevitable or trivial. Since sleep disturbance in older adults is common and distressing, it has implications for general health and well-being. Active concern and therapeutic intervention for the sleep habits and sleep disorders in the elderly are needed.

The aim of this study was to investigate the susceptibility of mutans streptococci (S. mutans and S. sobrinus) and Streptococcus anginosus, for seven antibiotics, penicillin G, amoxicillin, ciprofloxacin, cefuroxime, erythromycin, bacitracin, and vancomycin. The minimum inhibitory concentration (MIC) of seven antibiotics against 3 species (type strains) of mutans streptococci and S. anginosus, 10 strains (wild type) of S. mutans, 7 strains (wild type) of S. sobrinus, and 11 strains (wild type) of S. anginosus, were measured by broth dilution method. All of the type strains of mutans streptococci and S. anginosus had the same susceptibility for penicillin G, amoxicillin, cefuroxime and bacitracin. Type strain of S. anginosus was sensitive in ciprofloxacin, but those of mutans streptococci were not. All of the clinical isolates of mutans streptococci and S. anginosus had the same susceptibility for the seven antibiotics. Our data reveal that mutans streptococci and S. anginosus have similar antibiotic-resistant character. In addition, these results may offer the basic data to verify the antibiotic-resistant mechanism of mutans streptococci and S. anginosus.

A 36-year-old female patient with aplastic anemia developed massive hemoptysis and was placed on ventilator support. However, airway obstruction by blood clots triggered desaturation and ventilator malfunction. Manual ventilation was initiated to improve oxy-genation, and emergency flexible bronchoscopy was performed to clear the airway. Nevertheless, the patient developed extensive subcutaneous emphysema, pneumothorax, and pneumomediastinum.

OBJECTIVE: The purpose of this study was to compare the bacterial flora at the peri-implant sulcus of the orthodontic mini-implant placed in the alveolar mucosa with the bacterial flora at the adjacent healthy gingival sulcus. METHODS: Two plaque samples from 7 patients were collected by inserting paper points into the sulcus between the mini-implant and ligature wire connected to the mini-implant head and inflamed alveolar mucosa, and from the gingival sulcus of a healthy tooth adjacent to the mini-implant. RESULTS: Using 16S rDNA clone library, the 24 kinds of bacteria including Haemophilus aphrophilus, Sphingomonas species, Capnocytophaga species, Prevotella melaninogenica, Lachnospiraceae species, Porphyromonas species, Neisseria flava were identified only from the sulcus around the mini-implant. These bacteria constituted only 9.2% of total clones, and the bacteria identified from both the sulcus around mini-implants and the gingival sulcus constituted 80.4% of total clones. Of these bacteria, clones of Prevotella species, Atopobium rimae, Veillonella species, Streptococcus intermedius/constellatus, Streptococcus salivarius were more frequently isolated from the peri-implant sulcus. CONCLUSION: This study suggests that a broad epidemiological study is needed to find causative bacteria which induce inflammation from the peri-implant sulcus.
