Objectives: To compare the efficacy of two types specific exercise intervention (deep and superficial abdominal muscle exercises) in the treatment of patients with chronic low back pain (CLBP). Design: A randomized, comparative, repeated-measures. Subjects: Twenty-four patients with CLBP (at least for 3 months), mean age±SD=51.58±16.21 (yrs). Methods: Twenty-four patients with this condition were assigned randomly to two treatment groups. Both first and second group underwent 3 weeks specific exercise treatment program. The first group specific trained for the deep abdominal muscles. The second group specific trained for the superficial abdominal muscles. Results: After intervention, the first group showed a statistically significant reduction in pain intensity and functional disability levels (p<.05). The second group showed no significant change in these parameters after intervention (p>.05). Conclusions: According to results, a "deep abdominal muscle exercises" treatment approach appears more effective than a "superficial abdominal muscle exercises" treatment in patients with CLBP.

Controlled Release of BMP-2 from Alginate Nanohydrogels Enhanced Osteogenic Differentiation of Human Bone Marrow Stromal Cells

Lim, Hyun-Ju,Ghim, Han-Do,Choi, Jin-Hyun,Chung, Ho-Yun,Lim, Jeong-Ok 한국고분자학회 2010 Macromolecular Research Vol.18 No.8

A new controlled release system is proposed for bone morphogenetic proteins (BMP)-induced osteoblastic growth and differentiation of the human bone marrow stromal cells (hBMSCs) using injectable nanohydrogels. Alginate nanohydrogels (ANH) containing BMP-2 (BMP-2@ANH) were prepared using a reverse emulsificationdiffusion technique. The mean particle diameter of the BMP-2@ANH measured by dynamic light scattering was 520 nm. The proliferation of hBMSCs was promoted with the BMP-2@ANH. The controlled release of BMP-2 from the BMP-2@ANH enhanced the differentiation of hBMSCs into osteoblasts, which was confirmed by RT-PCR and alkaline phosphate activity. With the BMP-2@ANH, calcification and phosphate deposits on the cells were confirmed by alizarin red-S staining and von-kossa staining, respectively, showing that the differentiation of hBMSCs into osteoblasts was activated by the BMP-2 released from the BMP-2@ANH. Growth factor delivery using a nanohydrogel is a potential method for facilitating the differentiation of stem cells in vivo.

Background: The patient with an undifferentiated mass of the finger is frequently encountered in the clinic. But there is little discussion of tumors arising in the fingers in the dermatology literature. Objectives: To investigate the clinical characteristics of digit tumors. Methods: We retrospectively reviewed clinical photographs and medical records of 69 patients who visited Kangbuk Samsung Hospital for digit tumors between January 2013 and July 2017. The diagnosis are confirmed by skin biopsy. Results: The mean patient age was 48.57 years old, and the male-to-female ratio was 1:1.09. The most common digit tumor was pyogenic granuloma, which accounted for 34.78 % of the total number followed by mucous cysts (21.74%), masson’s hemangioma (7.25%). Furthermore, the most common digit tumor on the volar surface was identified to pyogenic granuloma (57.14%), and the most common digit tumor on the dorsal surface was revealed to mucous cyst (44.12%). Conclusion: Our study shows that various digit tumors can occur. Further studies with more large group are needed to better understand the incidence or site predilection of digit tumors.

Guttate psoriasis is a distinctive form of psoriasis that typically affects children, adolescents, and young adults. The lesions are 0.5-1.5 cm in diameter located on the upper trunk and proximal extremities. Streptococcal throat infection frequently precedes the onset of guttate psoriasis. However, vaccination is also reported to cause guttate psoriasis in some cases. The precise mechanism leading to guttate psoriasis after vaccination is unknown. There is a hypothesis that vaccination may be a triggering factor of guttate psoriasis by stimulating the immune system with an unexplained mechanism. A 68-year-old female presented with multiple scattered brown to erythematous scaly patches and plaques on the trunk and extremities, which occurred 5 days after influenza vaccination. The patient was otherwise healthy and had revealed no other disease within the preceding month. Histological findings of the lesion revealed mild spongiosis, exocytosis, superficial perivascular lymphohistiocytic infiltration, dilated blood vessels in the papillary dermis and focal subcorneal pustules. Finally, the patient was diagnosed with guttate psoriasis. The lesions were improved with narrow-band UVB and alitretinoin (Alitoc^®, 30 mg/day). We report a case with guttate psoriasis following influenza vaccination.

( Jae Yun Lim ),( Jung Yup Kim ),( Sun Min Lim ),( Ju Yeon Choi ),( Han Saem Kim ),( Jung In Kim ),( Jung Min ),( Joon Hong Min ),( Young Jun Choi ),( Jae Hui Nam ),( Ga Young Lee ),( Won Serk Kim ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1

Lipidized dermatofibroma is a very rare variant of dermatofibroma (DF). Lipidized DF occupies 2.1% among the variants of DF. It preferentially affects the lower limb, so it has been called “ankle-type” fibrous histiocytoma. Clinically, it presents as a solitary large exophytic yellowish to brownish nodule. Histologically, it shows acanthosis, irregular elongation of the rete ridge and fibroblast-like spindle cells in storiform pattern which are characteristics of the DF. Moreover it also contains abundant sclerotic collagen bundles surrounding foamy macrophages. Also, there is a hypothesis of relationship between serum lipid profile abnormality and lipidized DF. A 59-year-old female presented with asymptomatic solitary red to brownish 1.5-cm sized nodule on the left shin and solitary erythematous 1-cm sized nodule on the right calf, which were detected a year ago. Histological findings of the lesion revealed foamy macrophages surrounded by abundant sclerotic collagen bundles, distinctive stromal hyalinization, and spindle cells arranged in a storiform pattern. No cytologic atypia was observed. Abnormality of serum lipid profile was accompanied. Consequently, this case was diagnosed with lipidized DF.

( Jae Yun Lim ),( Junghwa Yang ),( Yun Ho Lee ),( Jung Yup Kim ),( Sunmin Yim ),( Ju-yeon Choi ),( Han-saem Kim ),( Jun Hong Min ),( Young Jun Choi ),( Jae-hui Nam ),( Ga-young Lee ),( Won-serk Kim ) 대한피부과학회 2017 대한피부과학회 학술발표대회집 Vol.69 No.1

Minocycline has increasingly been associated with different adverse reactions including drug-induced lupus (DIL). DIL is a less well-defined syndrome. Patients with DIL usually show the clinical features of polyarthralgia, polyarthritis often accompanied by liver abnormalities and positive antinuclear antibody test results. Representative dermatological manifestations are subcutaneous nodules, rash, livedo reticularis, oral ulceration, alopecia. A 20-year-old female presented with multiple erythematous, slightly elevated tender subcutaneous nodules on back, thigh and forearm. The patient had a past history of taking minocycline (Minocin^®, 50 mg/day) steadily for 10 months with acne. Two weeks after taking minocycline (100 mg/day) again due to recurrence of acne, new skin lesions as well as arthralgia were newly developed. Laboratory test for anti-histone antibodies and anti-SSA were positive. Histological findings of the skin lesion revealed mild septal panniculitis with mild lymphoid lobular infiltration. Finally, the patient was diagnosed with DIL. After stopping minocycline and taking hydroxychloroquine sulfate (Oxiklorin^® 200 mg/day) and methylprednisolone (Somelon^® 12 mg/day), arthralgia completely disappeared within 2 weeks. Herein, we report this patient as a rare and educational case of DIL triggered by long-term exposure to minocycline.

A case of combination treatment with oral acitretin and 5% imiquimod cream in an immunosuppressive patient with verruca plana

( Jae Yun Lim ),( Jung Yup Kim ),( Sun Min Lim ),( Ju Yeon Choi ),( Han Saem Kim ),( Jung In Kim ),( Jung Min ),( Joon Hong Min ),( Young Jun Choi ),( Jae Hui Nam ),( Ga Young Lee ),( Won Serk Kim ) 대한피부과학회 2016 대한피부과학회 학술발표대회집 Vol.68 No.1

Verruca plana is the subtype of the warts, which are one of the most common disease in dermatologic field. Verruca plana is induced by human papillomavirus 2, 10 and rarely by 28. Treatment modalities such as cryotherapy, CO2 laser and intralesional bleomycin are used in clinical field nowadays. Other modalities such as Q-switched Alexandrite laser are tried to treat the patients, who are recalcitrant to treatment. A 37-year-old man presented with asymptomatic multiple skin-colored, 1 to 2 mm sized, flat-topped papules on the both arms, neck and face, which last for about 2 years. The patient has been afflicted with ulcerative colitis (UC) for 15 years. Prednisolone and cyclosporin were used for about 14 years to treat UC. Histopathology revealed acanthosis and hyperkeratosis of the epidermis, and in part prominent granular layer. Finally, verruca plana was confirmed. The patient had been treated with 5% imiquimod cream for 6 months and only mild improvement was observed. Then acitretin (Neotigason^{®}, 0.45 mg/kg/day) was added. After 44 weeks of treatment, acitretin was stopped after gradually tapering the dose. Dramatic and rapid clinical improvement was achieved after 3 weeks of treatment and sign of recurrence after cessation of the treatment has not been reported for 24 weeks. Consequently, combination treatment with oral acitretin and topical 5% imiquimod cream should be recommended for the treatment of recalcitrant verruca plana.
