2.Eosinophil Leucocytes in Cantharidin Blisters of Patients with Various Dermatoss.
Korean Journal of Dermatology 1970;8(1):19-23
The increase of the eosinophil leukocytes can be taken as a sign of an allergic reaction it might be a helpful means for obtaining information on the etiology of diseases, therefore, examinations for eosinophil leukocytes in Cantharidin blisters was undertaken in normals and with various skin disorders. 1. In 30 healthy suhjects, blister eontained 56.47+42.5/mm3 of eosinophil leucocytes, and 80% of them never exceeded 66/mm3 of eosinophil leucocytes. 2. The highest eosinophil leukocytes among the various dermatoses was seen contact dermatitis (93.07+40.3/mm3) and drug eruption (92.17+21.1/mm3), atopic dermatitis (75.37+41.0/mm3), and chronic urticaria (72.28+24.2/mm3) were followed in order. 3. The eosinophil leukocytes were slightly increased in psoriasis vulgaris (69.14+29.9/mm3) and herpes zoster (63.25+20.4/mm3). 4. The eosinophil leucocytes were markedly increased in the skin disorders of allergic nature and slightly in non-allergic skin disorders.

3.Soft Tissue Perineurioma : A Case Report .
Korean Journal of Pathology 2009;43(3):266-270
Soft tissue perineurioma is a very rare tumor composed of entirely of neoplastic perineurial cells. A 54-year-old woman presented with a palpable mass in the right lower leg. The mass was excised. Grossly, the tumor measured 2.0x2.0x1.5 cm. The cut surface was well circumscribed, pale pinkish gray, and rubbery soft. Histological examination showed that the tumor was composed of spindle cells within collagenous and myxoid stroma. The tumor cells had elongated, tapering nuclei with long and thin cytoplasmic processes, and were arranged in fascicular, whorled, and storiform pattern. The tumor cells were positive for epithelial membrane antigen and collagen type IV and negative for S-100 protein. Ultrastructurally, tumor cells showed long and thin cytoplasmic processes, pinocytic vesicles, and incomplete external lamina. The diagnosis of soft tissue perineurioma was confirmed by immunohistochemical stain and ultrastructural study.

4.Reconstruction of the Old Flexor Tendon Injury in the Hand
The Journal of the Korean Orthopaedic Association 1995;30(2):334-342
The old flexor tendon injury in the hand seen after 4 weeks from damage and associated with crushing injury, heavy scarring, fracture and infectious state has the difficulty to deliver the flexor tendon through fibro-osseous sheath and the pulleys. Treatment method depends on the circumstances of the injured flexor tendon and surgeons' judgement. We have treated twenty-three fingers of twenty-three cases, who had old flexor tendon injury, by advancement and tenolysis in 1 each, tendon graft in 5, and staged tendon graft in 16 from March 1989 through February 1994. The result was summarized as follows. 1. The old flexor tendon injury most commonly occurred in the fifth finger(11 cases, 47.8%)and in zone II (16 cases, 69.6%). 2. The most common cause was glass injury(15 cases, 69.6%). 3. 21 of 23 cases(2 thumbs excepted)were evaluated according to the original Strickland system. 14 cases of the staged tendon graft showed excellent(6 cases, 42.9%), good(5 cases, 35.7%)and fair(3 cases, 21.4%). 5 cases of the tendon graft showed excellent(2 cases, 40%), good(1 case, 20%), and fair(2 cases, 40%). 1 case of adhesiolysis and 1 case of advancement showed excellent and good results each. Little difference is observed in the method between the staged graft and tendon graft. 4. The degree of the associated soft tissue injury should be evaluated by the experienced hand surgeon before surgery and the delicate balance between protection and mobilization during the postoperative weeks is important as well as the surgical skill.

Background and purpose:The skeleton is the most common site of tumor metastasis in lung cancer.Skeletal complications from bone metastasis,such as severe bone pain,functional impairment,may substantially reduce quality of life,in some situations,may result in death.We explored the efficacy of ibandronate combined with chemotherapy in treatment of lung cancer with bone metastasis.Methods:Sixty-four lung cancer patients with bone metastasis were randomized into two groups:38 patients in study group received normal chemotherapy combined with ibandronate,and 26 patients in control group received normal chemotherapy only.Results:The response rate of pain relief in the study group and control group was 71.1% and 42.3%,respectively(P=0.006).In study group,serum alkaline phosphatise and serum calcium was decreased after treatment by ibandronate combined with chemotherapy(P0.05).Conclusion:Ibandronate is safe and well tolerated. Ibandronate combined with chemotherapy is effective in relief of the pain caused by bone metastases and may inhibit bone metastasis.

Keratosis punctata of the palmar creases (KPPC) is rare skin condition characterized by punctiform hyperkeratotic pits confined to the palmar and digital creases. Although this condition has been regarded as a variant of classical punctate keratoses, there are some differences between classical punctate keratosis and KPPC. We herein report a case of KPPC in a 22-year-old man who had numerous, tiny, hyperkeratotic pits limited to the palmar creases of both hands with typical histologic findings.

Fractures of the proximal humerus occur more frequently in older patients but are seen in all ages and emerge epiphyseal separations. The objectives of treatment are restoration of all involved structures to normal anatomical state and a completely functional limb in the shortest time possible. One part and two part fractures were indicated in conservative treatment and surgical treatment in most of three, four part fractures. The results of treatment of forty four cases according to Neer's classification were analysed at the Department of Orthopedic Surgery, Chonbuk National University Hospital from Mar. 1978 to Dec.1985. The results were as follows. 1. The prevalent age distribution was third and fifth decade(48%) . 2. The most common cause of injury was slip down(14 cases, 32%). 3. The most frequent cases of the fractures in Neer's classification were two part fractures(22 cases, 50%). 4. Thirty one cases(71%) were treated by conservative treatment, twelve cases(27%) by open reduction and 1 case(2%) by prosthesis. 5. Good results were in 23 cases(52%) of one and two part fractures, fair in 17 cases(39%) and poor in 4 cases(9%) of two, three and four part fractures.

The treatment of acetabular fractures is composed of operative and conservative methods, however, they are still controversial. Generally, because the acetabular fracture involves the joint surface and one sequalae such as post-traumatic arthritis can follow treatment, therefore an accurate reduction and postoperative early mobilization to obtain the prevenation of joint stiffness and arthritis are required. In order to achieve these purposes, we have studied and done a comparative survey between conservative and operative treatment on 55 patients with acetabular fractures, who were treated at our department from Jan. 1982 to Dec. 1988. Results were obtained as follows. 1. The prevalent age was the third decade and the cause of injury was traffic accidents in the majority. 2. The most common type of fracture was a posterior wall by Letournel classification. 3. Satisfactory results of operative treatment were 76% and conservative treatment 47%. 4. The complications were post-traumatic arthritis, ectopic ossification, peroneal nerve palsy and skin infection. 5. In the majority of displaced acetabular fractures, ORIF was recommended.

Simple posterior hip dislocations requiring open reduction is very few and reported approximately 3% of all posterior hip dislocations and we have little comments of the various causes preventing or blocking a concentric reduction following traumatic posterior hip dislocation. In a review of eleven cases of posterior dislocation requiring open reduction, we divided two groups, one is a failed closed reduction group, the other is a nonconcentric reduction group. A concentric reduction was prevented from an inverted limbus or an osteocartilagenous loose body from acetabulum or femoral head.
