Core decompression is still widely used in avascular necrosis of the femoral head but the results are unpredictable and the indications are not settled yet. The reparative process of the decompressed femoral head is poorly understood. Seven cases in 5 patients were undertaken THRA following failed decompression and these were studied for the radiological and pathological changes of the core tracts. The lesions of failed cases were involved more than 1/3 of femoral head on MRI and all cases were stage II A or B. The extent of the necrotic area in MRI was enlarged with crack, sclerosis and sometimes gas collection. Depression of the subchondral plates were also observed. Capillary ingrowth or neovascularization was not found at all and there were only fibrosis, inflammatory response and foreign body reactions.

Radiologic findings of the 29 cases of radiation pneumonitis and fibrosis diagnosed by chest radiography atSeoul National University Hospital were evaluated and compared with clinical symptoms according to the passage oftime after radiation therapy. The resuls were as follows; 1. The first radiographic signs of radiation pneumonitisand fibrosis were observed 7.6 weeks and 19.3 weeks after radiation therapy respectively. Especially in 8 cases ofsmall cell ca., they were found 5.6 weeks and 10.4 weeks, appearing slinghtly earlier than those of 12 cases ofsquamous cell ca. of lung. 2. The appearing time and severity of the radiographic changes of radiation pneumonitisand fibrosis had no specific relationship with field size, tumor dose or time-dose-fractionation factors of thetreatment. 3. The most constant and characteristic radiological finding of radiation pneumonitis was the sharp andstraight margin of the lesion, which was not that of normal anatomical structures of the lung. Other findings werediffuse haziness, indistinct normal pulmonary markings, alveolar and nodular densities, air-bronchograms andindistinctness of heart border. In radiation fibrosis stage, the lesion characteristic and constant finding. Otherfindings were indistinctness of heart border, diaphragmatic tenting and compensatory emphysema.

PURPOSE: To compare the tissue reactions of various water-soluble and oil-based contrast agents on the endometrium, salpingeat mucosa, and peritoneum. MATERIALS AND METHODS: Thirty-three rabbits were used for evaluating the histologic reactions of uterine endometrium, salpinx, and peritoneum. Hysterosalpingography(HSG) was underwent in these rabbits by using Lipiodol, Hexabrix, Rayvist, Ultravist-300, Ultravist-370, and normal saline. Pathotogic results were obtained in each of the six groups from the uterine endometrium, salpingeal mucosa, and peritoneum without knowledge of the contrast agent used and time interval from HSG. RESULTS: Mild inflammations were observed in the endometrium, salpingeal mucosa, and peritoneum during the first week of HSG in all rabbits in which water-soluble contrast agents were used. Although there was no significant difference in the degree of inflammation among the groups using various contrast agents, the group with oil-based contrast agent(Lipiodoi) showed delayed absorption of contrast agent in the peritoneum, frequent intravasation, fat granuloma, peritoneal adhesion, or uterine infarction. CONCLUSION: Our results suggest that water-soluble contrast agents can be used safely for HSG, but the use of oil-based contrast agent is questionable in safety and should be avoided in patients with tubal obstruction, salpingitis, or endometritis.

Spontaneous testicular hemorrhagic necrosis is a rare disease usually associated with testicular torsion. Partially involved and suspicious testis tumor cases are also defined from orchiectomy specimens. Herein, a spontaneous hemorrhagic necrosis, without any testicular torsion, but with involvement of the whole testicle and epididymis, is reported. A 21 year old patient, who presented with a painless left testicular enlargement of several days duration was believed, based on physical examination, ultrasonography and elevation of serum LDH, to have a testicular tumor. Diagnosis was made only after radical orchiectomy and histopathological examination.

OBJECTIVE: To evaluate the effect of neuromuscular electrical stimulation (NMES) therapy on swallowing dysfunction in patients with chronic (more than 6 months) dysphagia caused by stroke. METHOD: A total of 16 patients with stroke-caused swallowing disorders based on a videofluoroscopic swallowing study (VFSS) were treated with NMES for two weeks. NMES was applied to the skin over the anterior neck muscles for one hour a day. Swallowing function was evaluated by the functional dysphagia scale using the VFSS, clinical dysphagia scale and the American Speech-Language Hearing Association National Outcomes Measurements System Swallowing Scale (ASHA NOMS scale) before and after electrical stimulation. Follow up VFSS was performed one month after intervention. RESULTS: After completing ten treatment sessions, aspiration, reflex coughing and the total score in the clinical dysphagia scale were significantly decreased (p<0.05). There was also a significant improvement in the ASHA NOMS scale (p<0.05). Regarding the functional dysphagia scale, the residue in the valleculae and piriformis sinus, and total scores were significantly decreased (p<0.05). Specifically, the scores of the pharyngeal phase were mainly decreased as compared to that of the oral phase. In addition, these effects were maintained one month after the intervention as measured with functional dysphagia scale. CONCLUSION: After ten sessions of NMES, we found improvement in dysphagia parameters in chronic dysphagia patients. Specifically, residue in the valleculae and piriformis sinus, and a parameter of the pharyngeal phase were significantly improved.

Gastric surgery is one of the most frequently performed operations in Korea. Retroanastomotic hernia is a rare complication ingastric surgery. We experienced this hernia and herein report it with a review of the literature. A 69-year-old male patient suffered from periumbilical pain for 3 days. Positive physical findings were tenderness around the umbilicus and decreased bowel sound. Simple abdominal findings revealed a mechanical obstruction. This patient had a history of gastrectomy 13 years prior to admission. At operation field, we were able to find the defect consisting of the transverse mesocolon, stomach, jejunum and retroperituneum. In Korea, since its first report by Petersen, only a few reports about this hernia have been reported. After increased incidence of operations for morbid obesity, reports on retroanstomotic hernia have increased.

PURPOSE: The objective of this study was to assess the supportive needs of breast cancer patients and determine the socio-demographic and clinicopathological predictors of those unmet needs. METHODS: Of 302 eligible breast cancer patients, attending Yonsei University Severance Hospital, 250 completed the surveys. The supportive care needs were assessed by administering a Supportive Care Needs Survey. RESULTS: Of the ten highest perceived needs items, 7 items were related to the health system and information domain and 2 to the psychological domain. The univariate analysis in each domain showed education (P=0.083) and chemotherapy (P=0.042) were significant predictors in the psychological domain; education (0=0.000), time since surgery (P=0.009), node metastasis (0.022), chemotherapy (P=0.001) and radiation therapy (P=0.003) in the physical and daily living domain; age (P=0, 009) and duration of marriage (P= 0.004) for sexuality; node metastasis (P=0.048), TNM stage (P=0.036), and recurrence (P=0.010) in the health system and information domain and religion (P=0.016) in the care and support domain. A multivariate analysis showed age (P=0.0253) and chemotherapy (P=0.0517) as significant independent predictors in the sexuality domain; education (P=0.0010), chemotherapy (P=0.0011), radiation therapy (P= 0.0133) and time since surgery (P=0.036) in the physical and daily living domain; recurrence (P=0.0324) in the health system and information; domain and education (P=0.0134) and chemotherapy (P=0.0207) in psychological domain. CONCLUSION: Breast cancer patients experience high levels of unmet supportive needs across each domain, but especially in the health systems and information domain. Also, the types of needs varied according to the patient subgroups. This study suggests considerable improvements be made in terms of supportive care of breast cancer patients.

Neurofibromatosis, first clearly described by von Recklinghausen in 1882, is a dominantly inherited mesodermal and ectodermal dysplasia with a broad spectrum of clinical findings. Most common is the classical neurofibromatosis, which has three major features: (1) multiple neural tumors dispersed anywhere on or in the body; (2) numerous pigmented skin lesions, some of which are "cafe au lait" spots; and (3) pigmented iris hamartomas also called Lisch nodules. Other lesions sometimes seen in patients with von Recklinghausen's disease include congenital malformations of various types, vascular lesions, neurilemoma meningioma and other intracranial neoplasms, pheochromocytoma, medullary carcinoma of thyroid gland, neuroblastoma, ganglioneuroma and Wilms' tumor. Approximately 10% of the patients with neurofibromatosis have the gastrointestinal tract tumors as neurofibroma, ganglioneuroma and leiomyoma. Some of them show evidence of malignancy. Increased activity of the protein "nerve growth factor" in the sera of the patients with disseminated neurofibromatosis has been reported. We would like to report here two cases of von Recklinghausen's neurofibromatosis with involvement of the gastrointestinal tract.
