Lichen striatus is an uncommon nonspecific inflammatory cutaneous disease of unknown etiology occuring as unilateral and linear distribution on extremities and healing spontaneously within a few months to a year. Clinically it is composed of small licbenoid papules which tend to be grouped and coalesced to form either a continuous or an interrupted hypopigmented band and is not usually accompanied by any subjective symptoms. The principal histologic features are an infiltrate composed of lymphocytes and histiocytes around papillary vessels and usually also around, some of the deeper vessels and skin appendages and consequent secondary changes of the epidermis. We present the results of clinical and histopathologic observation in 19 patients with lichen striatus observed at Department of Dermatology, National Medical Center and Seoul National University Hospital during 4 years period from l972 to 1976 which would be the first recorded report on this rare disease in Korea. 1. Clinieal Observation.' Among the 19 patients, 10 were female and 9 were male; 15 were under 10 years of age and 4 were over 10 years of age. Duration of the eruption varied from 1 week to 4 years and average duration was 9.6 months at the time of the first visit. It was unilateral in all cases and affected the upper extremities in 9 and the lower extremities in 8 instances. The eruption extended onto the upper part of the trunk in 2 cases. Only 3 patients had a history of mild intermittent itching sensation. Characteristically, the eruption consisted of grouped, linear, slightly scaling flat polygonal papules with varying degrees of hypopigmentation, extending at least onethird of the length of an extremity. . Histopathologic observation: Skin biopsy was performed in 13 cases. The epiderrnal changes consist of mild diffuse hyperkeratosis (13 cases), focal parakeratosis (5 cases), varying degree of atrophy of malpighian layer (7 cases), mild acanthosis (2 cases), intercellular and intracellular edema (8 cases), exocytosih of lymphocytes (7 cases), focal basal cell disruption (11 cases), and dyskeratotic cells (colloid body) (2 cases). Dermal changes include mild to moderate perivaacular lymphocytic and histiocytic infiltrate rnostly on the level of papillary dermis. Also, there was chronic infIammatory cell infiltrate around hair follicle and sweat glands and ducts in 7 cases respectively, which seems to be peculiar in this disease. Overall histologic findings in our cases are generally consistent with those of the primary phase of the so-called lichenoid tissue reaction of Pinkus, The possible pathogenetic mechanism of the linear eruption and immunobiologic interpretation of the lichenoid tissue reaction were literally reviewed.

This case report introduces a 74-year-old male patient who visited retention deficiency of the mandibular implant overdenture, which was fabricated 20 years ago.When the existing dentures were used, the vertical dimension was reduced, the maxillary complete denture lacked lip support and retention, and the mandibular overdenture lacked clip retention due to damage to the bar attachment. After removing the damaged bar attachment, it was replaced with a ball attachment, and impressions were taken using the DENTCA TM Tray and then the vertical dimension was measured. The gothic arch tracing was performed to record the centric relation. Obtained impressions were scanned and the shape of final dentures was designed using software and try-in dentures were fabricated using 3D printer.After evaluating the occlusal plane, occlusal relationship, facial shape, and pronunciation using the try-in dentures, the bite registration was recorded, and the final denture was manufactured based on this. The inner surface of the denture was adjusted and bilateral balanced occlusion was formed, and the housing was connected to the mandibular denture by a direct method. This case reports have shown satisfactory resultin recovering improved retention and esthetic outcome by increasing the vertical dimension and the lip support using CAD-CAM technique and the ball attachment.

BACKGROUND AND OBJECTIVES: Allergic rhinitis (AR) and rhinitis medicamentosa (RM) have different mucosal color and pathophysiology. To investigate whether the mucosal color and nasal blood flow are different between the diseases in spite of same symptoms, we designed this study. Materials and Methods: 20 patients with allergic rhinitis and 21 patients with rhinitis medicamentosa were compared with 20 normal volunteers using mucosal color grading and Laser Doppler flowmetry. The Laser Doppler flowmetry was performed with a Periflux 4001 (Perimed, Jrtlla, Sweden) and perfusion unit (PU), velocity unit (VU), and concentration Unit (CU) were measured. The Laser Doppler flowmetry data in AR and RM were compared with those of the normal subjects, and between AR and RM. RESULTS: The perfusion score of AR and RM were lower than the control (p<0.05) and it was statistically significant that the mucosal color of AR were pale and of RM were reddish, comparing to the control group (p<0.05). CONCLUSION: The nasal blood flow was decreased with AR and RM compared to control but the mucosal color of AR and RM were different because of the difference of pathophysiology of diseases. When diagnosing RM, observation of mucosal color and measurement of nasal blood flow will be helpful besides the history of long-term use of nasal decongestant.

Tensor fascia lata myocutaneous flap is the most useful local flap in surgical treatment of greater trochanteric sore. But the small volume of muscle included in Tensor fascia lata myocutaneous flap makes the thickness of flap thinner and the rate of recurrence higher than any other muscle flap. To overcome this disadvantage, Scheflan(1981) used distal folded Tensor fascia lata myocutaneous flap in treating greater trochanteric sore. But Scheflan used this flap as an island flap, that made the blood supply unstable and unreliable, and required skillful technique. And he didn`t use distal part of the thigh which made the efficacy of flap bulk small. In order to thicken the flap bulk, we used the distal folded tensor fascia lata myocutaneous flap. We have treated 10 patients by using newly designed distal folded tensor fascia lata myocutaneous flap. All of them had previous systemic disease. Some had general paresthesia and others had heart failure, diabetic mellitus, neuralgia and so on. We drew V-shaped design, one wing was from the anterior superior iliac spine to the lateral condyle of the femur and the other wing was from the center of the greater trochanter to the lateral condyle of the femur. After design, we harvest the flap and fold the flap two or three times. Flap bulk is enough to prevent sore recurrence. We follow up the patients from 6 months to 35 months. No recurrence is occurred. Our newly designed flap has sufficient volume and reliable blood supply. The result is good and satisfactory.

As a high-performance polymer, Polyetherketoneketone (PEKK) has good biocompatibility and excellent physical properties and is used in several areas, including dentistry. Many successful cases of implant-supported fixed prostheses with a PEKK framework have been reported; however, a long-term observation of the reported cases and discussion of complications are not available. In this case report, we present three cases of implant-supported fixed prostheses with a PEKK framework veneered with composite resin, lithium disilicate crown, and high-impact polymethyl methacrylate (PMMA), and discuss their 6-year follow-up results.

The sacral area is the most frequent site of pressure sore. Because bony prominence is broad and flat along with little soft tissue padding. Between many muscle flaps, the gluteus maximus myocutaneous flap is the most reliable one for surgery of sacral pressure sores. After complete resection of ulcer, the gluteus maximus muscle detached from its original site including posterior iliac crest. After adequate dissection proceeded and bony prominence removed, flap repair is done at the central line. When performing this flap, most surgeon use elliptical design and incision. In the past, we also used elliptical incision and sometimes experienced some drawbacks especially when wound extended close to anus. There are difficulties on repair of perianal skin, central tension of long vertical scar, perianal skin adhesion and natal cleft distortion and resulting asymmetry of gluteal contour and contamination of operation site by defication. After review of the photographs in the references dealing with pressure sores, we had an impression that there are skin adhesion near the anus in some cases and actually experienced such cases in other surgeon's operations. This time, we applicate new design called the "Bomb-shape" design when performing this flap to patients who have a broad wound extent close to anus or perianal skin. The "Bomb-shape" design is a concept of adding bilateral subcutaneous incisions to lower part of classic elliptical incision and we named as such because it resembles the military bomb in shape. We expect the effect of preserving the perianal skin and preventing the skin adhesion or natal cleft distortion and performed this procedure in 15 patients whose defect close to anus. Consequently, benefits of this method are spreading tension of vertical scar, decreased contamination in wound care, earn skin stability without perianal skin adhesion or natal cleft distortion, so maintain the symmetry of gluteal contour and get better cosmetic result. There is no significant increase in operation time in that no need of handling the "dog-ear", and all 15 patients have good results and are satisfied, so we introduce this flap design carefully with concurrent review of literature.

PURPOSE: The purpose of this study was to evaluate the effect of healing abutment height and measurement angle on implant stability when using Periotest and AnyCheck. MATERIALS AND METHODS: 60 implants were placed into artificial bone blocks. After implant insertion, 2, 3, 4 and 5 mm healing abutments were installed on 15 specimens, respectively. Insertion torque value, implant stability test, Periotest value were measured. Insertion torque value was controlled between 45 – 55 Ncm. AnyCheck was used for measuring implant stability test and Periotest M was used for measuring Periotest value. Implant stability test and Periotest value were measured at the angles of 0 and 30 degrees to the horizontal plane. Measured values were analyzed statistically. RESULTS: Insertion torque value had no significant difference among groups. When healing abutment height was higher, implant stability test and Periotest value showed lower stability. Also when measurement angle was decreased, implant stability test and Periotest value showed lower stability. CONCLUSION: When measuring stability of implants with percussion type devices, measured values should be evaluated considering height of healing abutments and measurement angle.
