Romberg syndrome is a rare disease and characterized by unilaeril atrophy of the skin, subcutaneous tissue and the underlying structure of half the face. The lesion does not usually cross the midline of the scalp. Roriberg syndrome is sometimes mildsnosed as linear scleroderma, although they differ widely in their clinical and histological apperance. A 13-year-old boy was present with a one year history of idefined atrophic patch on the left side of face and neck. We involved skin was not bound down to the underlying structure. The history revealed no prcvious trauma or disease, He had no abnormal neurologic finding. Computerized tomography demonstrated a diminished subcutaneouat volume and also decreased thickness of back muscle is the left side face from cheek to neck.

The toxic action of benzene on erythropoiesis and myelopciesis, has been recognized since the early years of the present century. With the advance in high civilization and modern covenience, benzene as a kind of aromatic compound has been used for industrial solvent and its longstanding use has committed a public nuisance to be overcome by medical approach. Chromosomal breakage and rearrangement may be produced by radiation, radiomimetics, virus infection and various chemicals, especially, antibiotics and antitumor agent, causing chroimosomal rearrangement in vitro, whose teratogenic action in rats was previously demonstrated. Several works hsve been published on the chromosome damage as a consequence of benzene intoxication. Recently, it was shown by certain workers that individuals who had been exposed to atmospheric benzene, even without haematological disorders, might have an elevated percentage of structural chromosome aberrations in the lymphocytes cultured from their peripheral blood. Moreover, structural and numerical chromosome aberrations were demons trated in patients with blood disorders which were believed to be due to exposure to beuzene vapors. Accordingly, much interest has been paid to its cytologic effect on the hematopoietic tissues in man and experimental animals. A high incidence of chromosomal aberrations has also been found in rabbits exposed to benzene during a period of peripheral pancytopenia and after hematologic recovery. The significance of these findings was discussed in relation to leukemic transition and to their diagnostic value in human benzene intoxication. Chromosomal anomalies can also be induced by benzene given subcutaneously to rata. A pronounced individual variation of the degree of chromosome damage was shown. The purpose of this investigation was to determine whether benzene could a direct effect on the chromosome complement of mammalian bone marrow cells in vivo and whether characteristic banding patterns might be demonstrated in rat chomosomes by a modified trypsin-Giemsa method. Four-week old Sprague-Dawley strain rats of both sexes(each weighing about 50gm) were used for this experimental study. Three groups of animals were treated-with subcutaneous infections of pure benzene. Group I received benzene, 2.0ml per kg body weight, 24 hours before sacrifice; Group II, 48 and 24 hours and Group III, 72, 48 and 24 hours. A control group was given no treatment. The animais were sacrificed in ether anesthesia. Femur and iliac bone marrow cells were suspended in medium 199 within 30 minutes and transferred to warm Hanks-distilled water(1:3) for hypotonic treatment(10 minutes). A freshly prepared solution of methanol glacial acetic acid (3:1) was used as fixative. Finally, a few drops of the cell suspension were placed on moistened, pre-cleaned slides being dried by rapid-drying technique. The slides were stained with either simple Giemsa or trypsin Giemsa banding technique. From the data obtained, this report was summarized as follows: 1. For the benzene-treated groups, chromosomal aberration rate was 13.4% in group II and 38.6% in group III, while in the controls the rate was 6.4 percent. 2. Numerical aberrations included aneuploidy, polyploidy and monoploidy. The most frequent type was hypodiploidy (5.8–9.4%) in all the treated groups. 3. Structural aberrations could be divided in gaps, ring chromosomes, breaks, deletions, exchanges and dicentrics. Among those, the majority of abnormal metaphases was gaps; 2.4%, 2.2% and 10.8% in group I, II and III respectively, and 1. 6% in control group. 4. The translocations and dicentrics were not demonstated in group I and II. 5. The normal chromosome set of the Sprague-Dawley rat was comprised of 42 chromosomes: 20 pairs of autosomes, and one pair of sex chromosomes, xx or XY chromosomes. The total number of major bands in s chromosome complement was about 40 and minor bands, 13, 6. Sucessful demonstration of banding patterns was available by proper adjustment of the concentration, temperature and duration of trypsin solution.

8.Fracture of the Coracoid Process Associated with Acromioclavicular Dislocation: A Case Report

Fracture of the coracoid process are rare and those associating with a complete acromioclavlcular separation is even more rare. The mechanism of injury may be attributed to either direct or indirect trauma. Most coracoid fractures are minimally displaced because It is by maintained by the coracoclavicular ligament and coracoacromial ligaments. Usually good result is obtained In the coracoid fracture by non-operative treatment. On the other hand open reduction Is rarely Indicated. The case we are reporting was treated by open reduction and Internal fixation of the acromloclavicular joint using two Kirschner wires, and screw fixation was done for the fracture of the base of the coracoid process. Review of the literature ls also done.

Synovial sarcoma is comparatively uncommon and highly malignant tumor, which usually arises in proximity to a joint and may affect the adjacent bones. Occurence in finger and severe bony involvement are rare. We present a case of synovial sarcoma of the thumb, because the tumor arose in an unusual site and was characterized by severe bony destruction.

The present study is an observation of 678 cases of children's fractures; which was treated in the Dept. of Orthopedic Surgery, inchon Christian Hospital, for the past ten years, from 1968 to 1978. The peak age was in from 5 years to 6 years. The sex ratio was 2.9 male to 1 female. The ratio between the right and left extremity was nearly equal. The frequency of fracture of the upper extermity was silghtly dominant then lower extremity. The cause of fracture was fall down Injury in nealy 70% of all cases. The epiphyseal Injury was noted as 16.8% of total orthapedic cases. The most common type of Salter & Harris Classiflcation was type II or 56.1%. Mostly all of children's fractures were treated by closed method, and others were treated by open reduction. Complication Included 29 cases of changed carring angle 18 cases of traumatic arthritis and 8 cases of malunlted supracondylar fracture and 3 cases of postoperative Infections and 2 cases of radial nerve palsy and 3 cases of delayed ulnar nerve palsy of the elbow. In fractures of the femur, 3 cases of the peroneal nerve palsy and 2 cases of leg longth discrepancy was noted. Brief discussion and review of Iiterature is presented.
