PURPOSE: This study investigated the clinical and radiological outcomes of patients undergoing provisional fixation in conjunction with locking plate fixation. Miniplates were used as the reduction plates for the surgical treatment of severe comminuted metadiaphyseal fractures with an intra-articular fracture of the distal radius. MATERIALS AND METHODS: The radial length, radial inclination, volar tilt, and radial intra-articular step-off were measured preoperatively, postoperatively, and at one year after surgery in 12 patients (eight males, four females, mean age 55.4 years old). The patients underwent volar locking plate fixation with miniplate as a reduction plate for severe comminuted metadiaphyseal fractures with an intra-articular fracture of the distal radius. Clinical evaluations were conducted using the modified Mayo wrist score (MMWS). RESULTS: Bone union was achieved in all cases. The mean MMWS was 81.8 points, including two excellent, three good, and seven fair cases. Radiological improvements were observed in the average radial length (preoperative, 6.4 mm; postoperative, 11.8 mm), average radial inclination (10.2° to 22.4°), average volar tilt (−4.5° to 10.6°), and average radial intra-articular step-off (4.8–0.8 mm) (all, p<0.05). Radiographic measurements obtained immediately after surgery and at the final follow-up revealed insignificant decreases in radial length (0.6 mm), radial inclination (0.4°), and volar tilt (0.9°) (all, p>0.05). CONCLUSION: Miniplate fixation can be an effective treatment option as a reduction plate for the treatment of distal radial fractures, which is challenging to reduce and maintain due to severely comminuted metadiaphysis fractures with the intra-articular fracture.

Neonatal lupus erytematosus is a distinct subset of lupus erythematosus. It is characterized by cutaneous findings exhibiting the morphology of subacute cutaneous lupus erythematosus, congenital heart block, and anti-Ro/SSA and/or anti-La/SSB autoantibodies which result from the transplacental passage of maternal autoantibodies. We report a case of a 12-week-old female infant who presented with characteristic clinical and histopathological features of cutaneous neonatal lupus erythematosus but without evidence of congenital heart block. Initial serological studies reveled the presence of anti-La/SSB anti-bodies and antinuclear antibodies. 5 months later, follow-up serology was negative in accordance with a clinical remission.

A 38-year-old man presented with a black pigmented patch overlying his upper lip, a part of the gingiva and the hard palate. An intradermal tumor mass was palpated at the central portion of the pigmented patch of the upper lip. Diphenylcyclopropenone (DPCP) is a potent contact sensitizer that could stimulate non-specific immunity. We report a case of desmoplastic malignant melanoma (DMM) in which an atypical lentiginous pigmentation disappeared with topical DPCP immunotherapy and the dermal tumor mass was removed by a surgical wedge-shaped excision. Though an atypical lentiginous pigmentation of DMM sometimes undergoes extensive spontaneous regression, in our case it could be attributed to the therapeutic effect of topical DPCP immunotherapy rather than a spontaneous regression.

Fordyce's disease is a condition known as ectopically located sebaceous glands on the vermilion borders of the lips and oral mucosa. Clinically, it is groups of minute, yellowish, globoid macules and papules. Histologically, it is characterized by sebaceous glands not associated with hair follicles. We report on a 40-year-old man with Fordyce's disease showing particularly wide distribution on the buccal mucosa and upper lip.

Trichilemmal horn(trichilemmal keratosis) is a rare keratinizing tumor that resembles a cutaneous horn. Histologically, it is characterized by an abrupt maturation of keratinocytes into lamellar keratin without the formation of a granular layer. We describe a case of a trichilemmal horn on the right cheek of a 78-year-old woman.

We report a case of a 6-month-old female who had had verrucous hemangioma since birth. The lesions were dark red, verrucous surfaced, hyperkeratotic papules on the right sole. A histopathological examination showed hyperkeratosis, papillomatosis, irregular acanthosis, lobular proliferation and dilatation of blood vessels in the deep dermis with a gap devoid of vessel proliferation in the mid dermis.

Shiitake (Lentinus edodes) is a kind of mushroom which is cooked and eaten as a food in Chinese, Japanese and Korean meals. It is nowadays the second most commonly produced edible mushroom in the world. In 1985, a case characterized by itchy skin eruptions after the ingestion of raw shiitake mushrooms was reported and was termed as toxicodermia. Here we report five cases of shiitake dermatitis which developed after ingestion of raw or cooked shiitake mushrooms. All patients complained of severe itching and showed linear grouped erythematous papules after scratching(Kobner phenomenon). To our knowledge, this is the first report of shiitake dermatitis in the Korean literature.

BACKGROUND: Onychomycosis has become one of the common fungal infection. However, highly reliable and sensitive methods of detecting and identifying causative fungi of onychomycosis are not established yet. Polymerase chain reaction (PCR) analysis of clinical specimens including blood, sputum, urine, and cerebrospinal fluid collected from patient systemically infected fungus is known as a sensitive diagnostic method. But it has been questionable whether PCR analysis is also applicable to onychomycosis. OBJECTIVE: The purpose of this study was to develop a DNA-based diagnostic method to improve the sensitivity and specificity of detection and identification of pathogenic fungi of onychomycosis. METHODS: To detect the fungi in the nail, PCR was performed by using 4 sets of primer (TR1 & TR2, NS5 & NS6, B2F & B4R and CA1 & CA2) designed in conserved sequences of the small ribosomal subunit (185-rRNA) genes and restriction enzyme analysis of amplified product by Hae III was done to identify species. Nail specimens were obtained from 19 cases of onychomycosis confirm by fungus culture. RESULTS: 1. Preparation of nail powder, which is necessary for removal of keratin, and composition of lysis buffer with guanidinium thiocyanate, Tris-HCl, and beta -mercaptoethanol are the most proper modalities for isolation of fungal DNA from fungus-infesting nails. 2. Specific fragments of the 18S-rRNA gene of fungi, 581 bp, 308 bp, 688 bp and 1106 bp were amplified respectively. From sequences of 18S-rRNA gene of fungi by universal primers, dermatophytes (Trichophyton rubrum, Trichophyton mentagrophytes) and yeast (Candida albicans) yielded identical products. 3. Using Hae III endonuclease, digested patterns of fragment of Trichophyton rubrum and Candida albicans resulted in different pattern. CONCLUSION: This method released enough DNA from fungus-infected nails to result in proper amplification and it can be possible to differentiate dermatophytes, yeasts, and molds using Hae III endonuclease. The present study is the first one to demonstrate the feasibility of this molecular biologic approach to identify fungi in the infected nail. Therefore, precise detection and identification of the causative fungi would be of help in investigating distribution of the causative fungi of onychomycosis as well as appropriate treatment of the disease.

Hirsutoid papillomas of vulvae present as smooth or filiform papules located on the inner surfaces of the labia minora. This disease is usually considered as anatomical variants of the vestibular mucosa. Differentiation from condyloma acuminata is important to avoid unnecessary treatment. Herein we report a case of hirsutoid papillomas of vulvae in a 21-year-old female who complained of pruritic papules on the vulva of one year's duration. Papules were located on the inner surfaces of the left labia minora and vestible of the vulva. Clinically, they were quite similar to condyloma acuminata. Histologically, however, the epithelium was devoid of features of human papillomavirus(HPV) infections such as koilocytosis, double nucleation, and dyskeratosis.

OBJECTIVE: The aim of this research was to evaluate the mechanical properties (MP) and degree of the phase transformation (PT) of martensitic (M-NiTi), austenitic (A-NiTi) and thermodynamic nickel-titanium wire (T-NiTi). METHODS: The samples consisted of 0.016 x 0.022 inch M-NiTi (Nitinol Classic, NC), A-NiTi (Optimalloy, OPTI) and T-NiTi (Neo-Sentalloy, NEO). Differential scanning calorimetry (DSC), three-point bending test, X-ray diffraction (XRD), and microstructure examination were used. Statistical evaluation was undertaken using ANOVA test. RESULTS: In DSC analysis, OPTI and NEO showed two peaks in the heating curves and one peak in the cooling curves. However, NC revealed one single broad and weak peak in the heating and cooling curves. Austenite finishing (Af) temperatures were 19.7degrees C for OPTI, 24.6degrees C for NEO and 52.4degrees C for NC. In the three-point bending test, residual deflection was observed for NC, OPTI and NEO. The load ranges of NC and OPTI were broader and higher than NEO. XRD and microstructure analyses showed that OPTI and NEO had a mixture of martensite and austenite at temperatures below Martensite finishing (Mf). NEO and OPTI showed improved MP and PT behavior than NC. CONCLUSIONS: The mechanical and thermal behaviors of NiTi wire cannot be completely explained by the expected degree of PT because of complicated martensite variants and independent PT induced by heat and stress.
