This study is performed to investigate whether free transplanted iliac physis can grow in the resected epiphyseal plate and prevent growth arrest secondary to an injury of epiphyseal plate. Growth arrest, angulation and regeneration of epiphyseal plate after free physeal transplantation from iliac crest in the partial resection of epiphyseal plate on the lateral aspect of the distal femoral epiphysis were analysed in process of time and compared with those of the simple partial resection of epiphyseal plate of distal femur. Seventy-six skeletally immature, three month-old rabbits with an initial weight of about 1200 to 1400gm were used for this study. The following experimental groups were made after partial resection of epiphyseal plate on lateral aspect of distal femoral epiphysis(2×7×3mm). Group A: partial resection alone(19 rabbits); Group B: muscle piece interposition(19 rabbits); Group C: free autogenous iliac crest physeal transplantation (38 rabbits). The opposite side of the leg was used as a control. Animals were killed and examined at the following time-intervals(14, 21, 30, 60 and 90 days after operation). The following results were obtained. 1. In the group of partial resections alone, the bone-brige formation between the femoral epiphysis and metaphysis revealed as early as 14 days, and this bridging was found consistently in all anlmals, which led to the growth arrest and valgus deformity. 2. In the group of muscle piece interpositions, the interposition materials were found temporarily effective for the prevention of epiphysiometaphyseal bone-bridge formation, but the effect was not significant to regain bone growth. 3. Histological studies showed that the grafted physis united with the residual part of the original femoral physis at 14 days after transplantation, and regained its columnar arrangement. The physeal graft appeared to be viable and contribute endochondral bone formation in following section (60, 90 days). 4. In the grodp of free autogenous iliaccrest physeal transplantations, the transplanted physis prevented or minimized the formation of a bone brige, growth arrest, and valgus deformity in most animals. Although not all of the physeal transplants were successful, physeal grafts would be most suceessful method regaining bone growth after focal injury of epiphyseal plate.

Traumatic hyphema accounts for about 6.7% of ocular trauma and its visual threatening associated ocular injuries are commotio retinae, retinal detachment, macular hole. cataract and rebleeding. The authors reviewed the medical records of 98 patients (98 eyes) having been admitted to the Joongang Gil Hospital between March 1989 and February 1991 with the diagnosis of nonperforating traumatic hyphema. Prospective study was performed as to the effect of epsilon-aminocaproic acid (EACA) in the clearance time of blood clot in the anterior chamber and the frequency of rebleeding. The avlrage clearance time of blood clot was significantly longer in the EACA treated group (5.8 days) than in the control group (3.5 days)(t-Test P<0.01). The frequency of rebleeding was not statistically significantly different between the EACA treated group (3.9%, 2/52 patients) and the control group (87%, 4/46 patients)(X2-Test P>0.05).

PURPOSE: The purpose of this study was to describe the clinical characteristics of neonatal urinary tract infection (UTI) caused by Klebsiella pneumoniae and non- Klebsiella pneumoniae UTI. METHODS: We compared clinical characteristics of 84 neonatal patients with UTI caused by Klebsiella pneumoniae who were hospitalized at the Department of Pediatricsat Han Dong University, Sunlin Hospital during the period between May, 1994 and August, 1998. The cases were divided into two groups depending upon causative organisms' Klebsiella pneumoniae UTI vs non-Klebsiella pneumoniae UTI, and the clinical characteristics of these groups were compared. RESULTS: Escherichia coli was the most common bacterial pathogen causing neonatal UTI, followed by Klebsiella pneumoniae. There was no significant difference in the sex distribution of Klebsiella pneumoniae UTI, but non-Klebsiella pneumoniae UTI showed male predominence. There were no significant differences in the incidences of hematologic, urologic, radiologic findings and perinatal complications in between these 2 groups. CONCLUSION: Klebsiella pneumoniae is the second most common pathogen causing neonatal UTI. There were no specific differences in the laboratory, symptomatologic, and radiologic findings in these two groups.

A clinico-pathologic study with an immunohistochemical examination for c-erbB-2 expression in 54 cases of ductal carcinoma in situ and 16 cases of Paget's disease of the breast was performed. c-erbB-2 oncoprotein overexpression was observed in 45% (24/54) and 88% (14/16) of ductal carcinoma in situ and Paget's disease, respectively. The overexpression of c-erbB-2 oncoprotein was significantly correlated with the nuclear grade of tumors and inversely with the status of the estrogen receptor. c-erbB-2 was positive in 4 out of 5 patients with metastasis to axillary lymph nodes and 3 out of 4 patients who died of the disease. Prognostic significance of c-erbB-2 oncoprotein in ductal carcinoma in situ was highly suggested. The expression of c-erbB-2 oncoprotein in Paget's disease was well correlated with coexisting infiltrating or in situ ductal carcinoma. The high positive rate of c-erbB-2 oncoprotein in ductal carcinoma with Paget's disease could be understood with a recent hypothesis that c-erbB-2 oncoprotein is involved in promotion of cell motility and the spread of carcinoma cells.

By Enzinger and Weiss classification, 664 cases of soft tissue tumors, which were confirmed histologically at the department of pathology of Hangang Sacred Heart Hospital from Janusry 1979 to December 1988, were analyzed statistically. The results were as follows : 1. Of the 664 cases, 261 cases (39.3%) were consulted at the Department of General Surgery, 124 cases (18.7%) were consulted at the Department of Orthopedic Surgery, 115 cases (17.3%)were consulted at the Department of Dermatology. 2, Of the 664 cases, 631 cases (95%) were benign and 33 cases (5%) were malignant. 3. The most common benign tumor was lipoma, which was followed by hemangioma and lymphangioma. Among malignant tumors liposarcoma was the most common one, followed by malignant fibrous histiocytoma. 4. The distribution of age of benign tumor was relatively even from childhood to old age but that of malignant tumor showed highest prevalence in 7th decade. 5. The distribution of sex of benign tumor showed male to female ratio of 1: 1.1 but that of malignant tumor showed male to female ratio of 1.5: l. 6. The predilection sites of benign tumors were head, neck and trunk, but those of malignant tumors were lower extremities and trunk. 7. Kinds of soft tissue tumors consulted at the Department of Dermatology were hemangioma, neurofibroma, lipoma, dermatofibroma, ymphangioma, leiomyoma, juvenile xanthogranuloma, xanthoma, keloid and neurilemmoma.

PURPOSE: This study was done to explore the relationship of social support and meaning of life to suicidal thoughts among patients with cancer. METHODS: Data were collected by questionnaires from 138 patients who had been in cancer treatment at medical clinics and 8 patients who were members of an internet cancer association. The data were collected between August and November 2009 and analyzed using SPSS 12.0. RESULTS: Of the participants, 47.3% reported having had suicidal thoughts and 16.4% had attempted suicide since the diagnosis of cancer. The study participants received most support from family members, but 73.3% reported experiencing an existential vacuum. The suicide attempt group had significantly higher scores according to gender, age, level of education, diagnosis, treatment modality, level of activity, caregiver and social support compare to the suicide thought group. Suicidal thoughts were negatively related to social support and meaning of life was positively associated with social support. Support from family and friends and diagnosis explained 50.0% of variance for suicidal thoughts with 36.0% of variance being explained by family support. CONCLUSION: Nurses should be able to identify risk factors for suicide in cancer patients. Prevention and intervention efforts need to be directed toward improving social support, family support in particular, and assisting patients finding meaning in life after a diagnosis of cancer.

Various types of horizontal reference planes are used for diagnosis, treatment planning and evaluation of treatment results. But these reference planes lack accuracy and repro- ducibility, and are mainly for Caucasian. Unlike the adult patients who have completed growth, the horizontal reference planes for growing children may change continuously during growth, Therefore this must be considered in selecting the horizontal reference plane. The purpose of this study was to investigate the angle formed by the Sella-Nasion(SN) plane and Frankfort-Horizontal(FH) plane and evaluate the angle formed by FH plane and other horizontal reference planes in relation to different skeletal maturity and malocclusion types. 540 subjects with no orthodontic treatment history were chosen, and hand wrist X-rays and lateral cephalometric X-rays were taken, According to SMA(Skeletal maturity Assessment)of hand -wrist X-rays, the subjects were classified into 3 skeletal maturity groups ; SMI 1-2 for group A, SMI 5-7 for group B and SMI 8-11 for group C. A second classification was made according to cephalometric analysis of lateral cephalograms. The subjects were classified into 3 malocclusion group ; Skeletal Class I,II and III malocclusion group. 10 measurements were evaluated. The results were as follow. 1. The angle formed by the SN plane and FH plane showed no difference among skeletal maturity groups, malocclusion groups, and between sexes. 2. The angles formed by the SN plane and FH plane were 8.27degrees+/-2.31degrees for males and 8.59degrees+/-2.24degrees for females. The average value for females and males was 8.42degrees+/-2.28degrees. 3. The angle formed by the FH plane and palatal plane was almost constant showing no difference among skeletal maturity groups, malocclusion groups, and between sexes( 1.0 9degrees+/- 3.21degrees).

PURPOSE: To evaluate the outcomes of modified medial rectus (MR) resection using a lowered amount of MR resection for recurrent exotropia after bilateral lateral rectus (LR) recessions. METHODS: Fifty-six patients, who underwent MR resection from 2003 to 2017 for recurrent exotropia after bilateral LR recessions, were included. MR resection was performed using modified MR resection with a smaller amount of resection than the standard of 4 mm resection at 20 prism diopters (PD) of exotropia. Postoperative surgical results at 1 month, 6 months, 1 year and 2 years were classified as a success (5 PD esotropia [ET]-10 PD exotropia [XT]), overcorrection (>5 PD ET), and undercorrection (>10 PD XT). The clinical factors affecting surgical results at postoperative 6 month and 2 years were also evaluated. RESULTS: The success rate was 78.2% at postoperative 1 month and 87.5% at postoperative 6 months. The overcorrection rate was 21.8% and the undercorrection rate was 0% at postoperative 1 month. At postoperative 6 months, the overcorrection rate decreased to 0% and the undercorrection rate was 12.5%. The success rate was 85.7% at postoperative 1 year and 66.6% at postoperative 2 years. There was no clinical factor affecting the surgical outcomes except the ocular alignment at postoperative 1 month. The deviation at postoperative 1 month was more esotropic in patients with success at postoperative 6 months and 2 years than that in patients with undercorrection (p < 0.05). CONCLUSIONS: The modified MR resection showed favorable results of 87.5% at postoperative 6 months and 85.7% at 1 year. The angle of deviation at postoperative 1 month was an indicator of subsequent surgical outcomes.

A case of metastatic adenoid cystic carcinoma of the lung, originated from the trachea, was diagnosed by fine needle aspiration. Although the cytologic features of adenoid cystic carcinoma have been well described, it is easy to confuse adenoid cystic carcinoma with more common primary small cell neoplasms of the lung, i.e., small cell carcinoma, well differentiated adenocarcinoma, and carcinoid tumor of the lung. The features distinguishing adenoid cystic carcinoma from these neoplasms include 1) tight, globular, honeycomb pattern of cells, 2) acellular basement membrane material in the lumen, and 3) cells lacking true nuclear molding and having bland chromatin pattern. The morphologic feature of metastatic adenoid cystic carcinoma in this case was so distinctive as to permit a definite diagnosis by aspiration cytology.
