BACKGROUND: The survival rate of children with neuroblastoma has been improved over 20 years, excluding the metastatic disease, in which it does not exceed 20% so far. New treatment modalities have been developed to improve the outcome in metastatic disease. Preoperative chemotherapy reduce the size, the vascularity and the adhesiveness, so increase the resectability of the primary tumor. This retrospective clinical study was designed to review the survival rate in neuroblastoma and to analyze the effect of preoperative chemotherapy in the view point of neoadjuvant therapy on long-term survival in advanced disease. METHODS: One hundred and thirty-four cases were reviewed from 135 patients with neuroblastoma registered at the Department of Pediatrics in Seoul National University Children's Hospital from January, 1985 till December, 1995. The survival rate was reviewed according to the stage. The age, sex of the patients, the stage, anatomical site of the tumor, the level of serum ferritin and neuron-specific enolase were analyzed for the risk factors on survival. RESULTS: Ranges of age at diagnosis were from 1 month to 166 months with the median of 39 months. Five year survival rates and five year disease-free survival rates were 100%, 100% in stage 1(n=5), 90.9%, 90.9% in stage 2(n=13), 43.4%, 40.6% in stage 3(n=19), 27.1%, 19.8% in stage 4(n=95) and 100%, 100% in stage 4S(n=2), respectively. In stage 3, five year survival rate was 52.5% in group receiving neoadjuvant chemotherapy, 28.6% in control group(P=0.02). Five year disease-free survival rate was also noted as 48.6%, 28.6% in each group(P=0.02). In stage 4, five year and ten year survival rates were 27.6%, 23.6% in group receiving neoadjuvant chemotherapy, 26.9%, 0% in control group(P=0.02). Five year and ten year disease-free survival rates were 14.3%, 14.3% in group receiving neoadjuvant chemotherapy, 20%, 0% in control group (P=0.11). In univariate analysis, the age, the stage, and the site of primary tumor appeared to affect the long-term survival. CONCLUSION: Neoadjuvant chemotherapy and delayed primary surgery contribute for advance in survival in advanced neuroblastoma via increasing the resectability of the primary tumor.

The development of a safe method of transfer of the greater toe for thumb reconstruction, using dorsalis pedis artery and the great saphenous vein, suggested the possibility of one stage microvascular transfer of the second toe for reconstruction of surgery. Based upon our part experience with microsurgical experiments, limb transplantation and toe-to-thumb transplantation since 1975, we accomplished the second toe-to-index transplantation done in Korea on October 24, 1979, and succeeded in one stage second toe-to-index transplantation in two cases. Following results were obtained. I. Free second toe-to index transplantation on making a index is the most excellent method of index reconstruction with results in minimum functional and cosmetic impairment. 2. Technically, skin incision, isolation of blood vessels and flexor tendon in preparation for transplantation of second toe is more difficult than that of greater toe. 3. The specialized microsurgical training with skillful technique is essential for success.

The os subfibulare is a relatively uncommon bony anomaly of the foot. It is usually found between the malleolus and talus and ossifies during adolescence or preadolescence. It can be demonstrated on routine anteroposterior ankle film of the foot. In 4 patients presented, the abnormality caused pain and frequent episodes of ankle strain. The pain was relieved in all patients treated by excision of the accessory bone.

Twenty two eyes of twelve infants with threshold or prethreshold retinopathy of prematurity were treated by using the Argon laser through an indirect ophthalmoscopic delivery system. Eyes that had persistent plus disease were retreated to the missed areas. Mean follow-up period was 8.1 months. 20 of 22 eyes were regressed and all of prethreshold ROP were regressed. Our results suggest that argon laser photocoagulation is as effective as cryotherapy in the treatment of ROP and excellent results can be obtained by treating prethreshold zone I or posterior zone II ROP. And laser treatment is better tolerated by infant, accurate, easy, less destructive and not requires general anesthesia.

PURPOSE: To describe radiologic differences between tuberculous pleural effusion and empyema on the basis of computed tomography(CT). MATERIALS AND METHODS: We reviewed retrosepectively CT findings of 50 patients with pathologically and grossly proved empyema. Twenty-two patients had empyema, and 28 patients had tuberculous pleurisy. RESULTS: CT findings known to be useful in differentiating tuberculous pleural effusion from empyema (1) contour and extent of pleural thickening, (2) mediastinal pleural involvement, (3)accumulation of extrapleural tissue and (4) change of ipsilateral thoraic volume of empyema. However, none of the above findings were helpful in the differential diagnosis of empyema. CONCLUSION: The differentation of tubrculous pleurisy from pyogenic empyema may be not possible with CT findings only.

To obtain adequate information of illumination and lens types for visual acuity test of low vision patient, the relation between various illumination and vision was evaluated. Visual acuity for near and effective lens types were examined. Among the 28 patients (of 36 eyes), intensities of illumination were set at 200, 500, 1000 and 2000lux and the lenses of biconvex, aspheric and aplanatic were tested. The best visible range of illumination for the low vision patients was 500-1000lux, with lower power diopter for the same visual acuity and with aspherin and aplantic lenses. Results attained by our study may be applied for appropriate condition of illumiation and type of lens in the low vision care.

Malignant neoplasm associated with long-standing pleuritis or empyema is rare but a critical complication. Among 67 cases which were reported in English and Japanese literatures the cause of empyema was considered tobe tuberculosis in 51 cases. The most common malignant disease associated with the long-standing pleural disease was non-Hodgkin lymphoma (NHL), and the majority of the malignant lymphomas were B-cell type. Detection of the malignancy combined with an empyema is difficult, however, chest radiograph or CT may show the evidence of malignant pleural disease. We report a case of pathologically proven T-cell type malignant NHL associated with chronic tuberculous empyema in a 66-year-old male patient.
