Recently there has been a noted increase in the incidence of traumatic bony gap in long bones due to accidents in industry, high speed traffic accidents and common gunshot accidents. There are several methods to treat traumatic bony gap such as bone graft (autogenous, homogenous and heterogenous), bone transplantation, periosteal osteogenesis and reinplantation of the extruded bone etc. The authors studied 26 patients of traumatic bony gap in the long bones which had been treated by autogenous bone grafting. The results of the clinical observation were as following; 1 The causes were shotgun accidents, vehicle accidennts and explosive accidents. 2 There was bony gap involved in 10 upper extremities and 16. lower extremities. The radius was the most common site in the upper extremity and the femur in the lower extremity. 3. The largest bony gaps were 10.5cm. in the tibia and next were 10.6cm. in ulna and 9.0cm. im humerus. 4. The period of the bony union in these cases was prolonged 1.5~3 times the usual healing period of simple fractures. 5. It was very important to prevent and control infection of the open fractures and to decide the correct time for bone grafting operation after healing of the infected wounds. We did the bone grafting sugery 2 or 3 months later after the infected wounds had been healed. 6 The authors could avoid some complications such as delayed union, shortening of the affected limbs and stiffness of the joints of the affected limbs etc.

Pagets disease has been well known disease in western countries, but it is extremely rare in orient and no case has been reported in Korea yet. It is a chronic osseous disease affecting middle and late life, characterized by progressive skeletal deformities which consist of excessive resorption and abnormal regeneration. We experienced a case of Paget's disease in a 57-year old man with involvement of pelvis, femur and skull, and confirmed with open biopsy.

The technique of the arthroscopic total meniscectomy of discoid meniscus is very difficult. Ikeuchi(1982) reported a technique of arthroscopic total meniscectomy of the lateral discoid meniscus by removal of 2/3 of the anterior part of the meniscus first and then by morselization. The purpose of this paper is to report a technique of arthroscopic total meniscectomy of the lateral discoid meniscus as a whole. During the period from October 1982 to October 1984, we had 12 experiences of arthroscopic total meniscectomy of the discoid meniscus and found good results, that is, little postoperative pain, short period of hospitalization and early restoration of joint motion without physical therapy. Complications are 3 cases of symptomless slight lateral instability and 4 cases of hemarthrosis.

Neurofibromatosis(NF) is a disorder characterized by its relative commonness, variability, and heterogeneity. It is usually expressed as a generalized form, but is rarely localized in a limited part of the body as a segmental form. In 1981, Riccardi classified NF into 8 types and a segmental form (type V) was defined by limitation of cafe-au-lait spots and/or neurofibroma on a given unilateral segment of the body. Recently we came across two cases of typical segmental neurofibromatosis. The First case was a 53-year-old woman with localized neurofibromatosis on the right T8,9 dermatome. The Second case was a 34-year-old man with localized neurofibromatosis on the right T5,6 dermatome. There were no cafe-au-lait spots, axillary frecklings, Lisch nodules or a family history in both cases. We report these rare cases with a literature review.

BACKGROUND: Pyogenic granuloma(PG) is a common lesion of the skin and mucous membranes. The gingival lesion developed during pregnancy termed epulis gravidarum is identical to PG. Many articles have appeared in the literature pertaining to this lesion and its putative relationship to the hormonal changes of pregnancy. Several clinical features such as association with oral contraceptive use and regression after delivery, suggest that PG may be a hormone-sensitive lesion. OBJECTIVE: Our aim was to determine whether estrogen or progesterone might affect the development of PG. METHODS: We performed immunohistochemical staining by using a monoclonal antibodies to estrogen receptor(ER) and progesterone receptor(PR) in 15 PG(pregnant women; 4 cases, non-pregnant women; 5 cases, and men; 6 cases). RESULTS: All 15 PGs were negative for ER. However, for PR, the degree of staining was different according to the patient group; pregnant women(3 cases[75%]: weak positive, 1 case[25%]: strong positive), non-pregnant women(3 cases[60%]: weak positive), and men(6 cases[100%]: negative). CONCLUSION: Our results suggest that estrogen or progesterone may not directly involve in the formation of these lesions. Further studies are needed to determine whether the other factors are related to the pathogenesis of PG.

BACKGROUND: Conventional echocardiography provides fundamental information about mitral valve morphology and function but is often subjective and has a relatively low specificity in evaluating valve calcific deposit, which is critical information for the preoperative decision. We hypothesized that mitral valvular calcification could be detected in standard two-dimensional echocardiograms of mitral valve in vivo by evaluating regional gray level(echo amplitude) using computerized image analysis so that we could overcome the subjectivity and low specificity of conventional echocardiography. METHODS: We tested this hypothesis by performing standard 2.5MHz two-dimensional echoes on mitral valve and myocardium in 30 patients with mitral stenosis, scheduled to undergo mitral valve replacement. We compared gray level of each region of interest in mitral valve and myocardium in stop-frame images with the degree of calcifications identified by pathologic and radiographic examinations. RESULTS: Ratio of mean gray level of mitral valve to mean gray level of myocardium was the most reliable value in evaluating degree of calcification. Quantitatively, region of calcification displayed the ratio of significantly higher value than that of no calcification. In case of anterior mitral valve, the ratio of the evident calcified region was greater than 3.11, that of the region without calcification was less than 2.42 and that of microcalcification was betwwn 2.42 and 3.11. For posterior mitral valve, the ratio of the evident calcified region was greater than 3.50, that of the region without calcification was less than 2.19 and that of microcalcification was between 2.19 and 3.50. The sensitivity and specificity of this method for assessment of degree of calcification was 75% and 100% for anterior mitral valve and 9% and 87.5% for posterior mitral valve. CONCLUSION: Mitral valvular calcification could be detected quantitatively in standard two dimensional echocardiograms of mitral valve in vivo by evaluating regional gray level(echo amplitude) using computerized image analysis.

: In order to observe the antigenic fractions in saline extract of adult Paragonimus westermani, proteins in the crude extract were separated by sodium dodecyl sulfate-polyacylamide gel electrophoresis (SDS-PAGE) in reducing conditions. The separated protein fractions were transferred to nitrocellulose paper on which 20 sera from human paragonimiasis were reacted and immunoblotted. Out of 15 stained protein bands in SDS-PAGE, 7 reacted with the sera. Of 14 reacted bands, 30 kilodalton(kDa) band was the most frequently reacted (95%) and was a strong antigen. Protein bands of 23 and 46 kDa were also strong antigens. Bands of over 150 kDa, 120 kDa, 92 kDa, 86 kDa, 74 kDa, 62 kDa, 51 kDa, 32 kDa, 28 kDa, 16.5 kDa and 15.5 kDa were also reactive but their frequencies of the reaction were variable.
