A 16-year-old girl developed pyoderma gangrenosum without underlying disease at first. She was treated with local cutaneous dressing and systemic oral prednisolone and minocycline for 10 months, imtermittently. After that, acute leukemia, which was undeterminated type, was developed 4 years after first onset. Since pyoderma gangrenosum may be a preindication of underlying disease, continual follow up check for systemic disease is required.

Any type of urticaria may affect as many as 20% person during their lifetimes, yet the causes of this disorder is established in no more than 20% of cases. So, 308 patients with urticaria(acute ; 73, factitial; 120, chronic;115) were evaluated for results of historical and laboratory tests. The results were summerized as follows,' 1. The disesse primarily affected 2nd % 3rd decade(46.2%) with predominance of woman than man (M: F=1: 1.4). 2. Ninety-seven(31.5%) had at least one abnormal finding in the laboratory tests but, may be twenty-three(7.5%) would have causal relationship. 3. We sought serologic markers of Hepatitis B virus infection in serum from 8(14%) of 57 patients with urticaria. Of these, 4 were found to have abnormal liver function. 4. Sixty-five had taken at least one sort of drug previously or just before urticaria developed, but, may be forty-six(14.9%) would have a causal relationship and the predisposing drugs were analgesics, antibiotics, common cold medication & vitamin etc. 5. The predisposing conditions were as follows ; pulmory tuberculosis, viral hepatitis, hyperthyroidism, tonsillitis & ascariasis, etc. Of these, eleven(3.6%) of this patients were newly found to have underlying diseases. 6. This study showed inciting factors of urticaria in 27.2%(84/308).

A histological and electron microscopic study were conducted in order to observe a morphological changing pattern of patellar ligament autograft after endoscopic ACL reconstruction. Seventeen patients among 117 consecutive series which underwent endoscopic ACL reconstruction from January 1990 to March 1995, were involved in this study according to the various follow-up periods. In second-look arthroscopic finding at 6 months follow-up after ACL reconstruction, reconstructed ACL was covered with synovium and round-shaped, and after the biopsy active bleeding could be seen. In histological study, 6 months follow-up, spindle or ovoid shaped fibroblast with hypercellularity, high crmp patterns of collagen fiber, and parallel arrangement of fibroblast to collagen fiber were noted. The cellularity of fibroblast decreased in according to periods of follow up. At 12 months follow up, spindle or ovoid fibroblast, its cellularity and arrangement pattern and crimp pattern of collagen fiber seemed to be almost similar to those of normal ACL. This similaryity continued up to 2 years and 2 months after reconstruction. In EM study, until 6 months follow-up after reconstruction, the graft showed randomly arranged fibroblasts with hypercellularity, which had abundant cytoplasm with marked irregular cytoplasmic borders and prominent nuclear indentation, Collagen fibrils were immature and showed a unimodel distribution with small diameter. At 12 months follow-up, elongated fibroblasts appeared, but these cells contained folded nuclei and abundant cytoplasm. Collagen fibrils had parallel arrangement and sparse cross striation, and comprised of mainly small fibrils and scattered large fibrils. After 24 months follow-up, the cellularity decreased more. The regular arrangement of collagen fibrils with wavy pattern similar to normal anterior cruciate ligament was noted. Two distinctive population of the small and large diameter of fibrils was also observed (bimodal distribution). At 26 months, the large and small collagen fibrils compresed a characteric bimodal pattern with parallel arrangement, but the majority of fibroblasts had irregular cytoplasmic contour, and abundant cytoplasm with increased organelles, which indicated the active function. These findings suggest that the graft are still immature even at 26 months in postoperative follow up despite considerable maturation of collagen fibril.

Empathy is an essential factor for establishing therapeutic relationship. Especially for pediatric nursing, the nurses need to know how to perceive children's feeling and thought and to express her understanding about them affectively. So, empathy is considered as an important concept in pediatric nursing. This study was attempted to measure the empathic ability of pediatric nurses by pediatric nurse and mothers of hospitalized children. The subject of this study consisted of 83 pediatric nurses and 106 mothers of hospitalized children in 4 hospitals in Seoul and 1 hospital in Kyung-Gi. Data were collected from Jan. 14 to Feb. 6, 1997, by the questionnaire method. The instrument for this study was the Empathic Construct Rating Scale : ECRS(60-item, 5 point scale). Data Were analyzed by descriptive statistics, t-test and ANOVA. Result of this study are summarized as follows : 1. Pediatric nurses perceived their empathic ability to be moderately high(Mn=3.71) The level of perceived empathic ability of the pediatric nurses showed no significance by general characteristics. 2. The mothers of hospitalized children perceived nurses' empathic ability to be moderate(Mn=3.27). The level of perceived nurses' empathic ability of the mothers of hospitalized children showed significant differences by the experience of hospitalization of the children and the age of the mothers. 3. The perceived nurses' empathic ability of the mothers was significantly low than of the pediatric nurses(t=6.50, P<.001). From the above results, it can be concluded. that the empathic ability of the pediatric nurses is not sufficient for caring children and mothers efficiently. So, the pediatric nurses' empathic ability is needed to improve through facilitative relationship training as refreshment in-service education program.

Tenosynovitis*

A 52-year-old woman was admitted with a palpable mass on the abdominal wall. This tumor had developed at the same site of a previously resected dermatofibrosarcoma protuberans. The biopsy specimen from the recurrent tumor revealed malignant fibrous histiocytoma. Immunohistochemistry with anti-CD34 antibody revealed diffuse linear positivity on the tumor cells of dermatofibrosarcoma protuberans and negativity on malignant fibrous histiocytoma. Anti CD34 antibody was valuable for a differential diagnosis of these two lesions.

Cytologic findings of malignant cells obtained by fine needle aspiration from a huge retroperitoneal malignant fibrous histiocytoma were described. The smears contained numerous malignant cells, isolated or in clusters, in a bloody background. The malignant cells had abundant pleomorphic foamy or acidophilic cytoplasm with occasional multilobated vesicular nuclei and prominent nucleoli. Dual differentiation, both histiocytic and fibroblastic types, and neutrophilic inflammatory background were diagnostic of this neoplasm. The report indicated that study of aspiration cytology specimen from a soft tissue tumor was a valuable adjunct to histologic examination.
