The depressive symptoms are frequent and important ones in the elderly population. We studied the various factors affecting the severity of depressive symptoms in the elderly population. The Korean elderly (more than 65 years old; n=490) in Seoul area (city) were studied on the identifying data and medical and psychiatric history, Mini-Mental State Examination (MMSE) Geriatric Depression Scale (GDS) Korean Depression Scale(KDS: under development)were also administered. In our study, the significant effect of sex, age, education, marital status, and the status of medical security on the severity of depressive symptoms were not found. Significantly higher GDS and KDS scores were found in the elderly who have more than one physical illness, subjective memory complaints, and seven life events. To examine the strength of association of these variables of depression, we conducted logistic regression. Depressive symptoms were associated with 1)the loss of spouse, 2)a current physical illness, and 3)low socioeconomic status. These results showed that depression in the elderly may be correlated with the loss of spouse, a current physical illness, and low socioeconomic status.

STUDY DESIGN: A retrospective study. OBJECTIVE: To analyze the clinical significance of the radiolucent zones surrounding pedicle screws. SUMMARY OF LITERATURE REVIEW: Clear zones have been suggested in pseudoarthrosis and a loss of fixation. However, few reports have clearly described the long-term course and clinical significance of clear zones. MATERIALS AND METHODS: The clear zones were evaluated in 399 patients with pedicle screw fixation after 6 months, 1 year, 2 years and 3 years. The patient was considered to be clear zone positive when 1 mm or greater circumferential lucency was confirmed around a screw on film from 2 or more directions. The time-course of the clear zones was examined with regard to age, number of levels fused, bone union, fusion method and reoperation. RESULTS: After 6 months, clear zones were observed in 124 patients (31.1%) but the clear zone-positive rate decreased with time. Clear zones were observed in 89 patients(22.3%), 44 patients(11.0%) and 41 patients(10.3%) after 1 year, 2 years and 3 years, respectively. No new clear zones had developed after 6 months. At the final follow-up, pseudoarthrosis was observed in 12 patients(3.0%). Among them, 11 were clear zone-positive and 1 was clear zone-negative. There was a statistically significant relationship between the clear zone-positive rate and multi-levels, older age and nonunion during following up. In addition, there was a relatively lower clear zone-positive rate in posterolateral fusion combined with posterior lumbar interbody fusion than only posterolateral fusion. However, the difference between them was not statistically significant. CONCLUSION: The presence of clear zones does not always mean pseudoarthrosis but clear zones persisting for more than 2 years after surgery have a higher rate of pseudoarthrosis.

Costoclavicular syndrome is one of the four syndromes of thoracic outlet syndrome in which have similiar symptoms, and may result from cervical and thoracic scoliosis, formation of excessive callus or nonunion after fractures of clavicle or first rib. Conservative treatment may be offered. Surgical treatment includes scalenectomy with supraclavicular approach, transaxillary first rib resection with scalenectomy and correction of clavicular abnormality. The purpose of this paper is to evaluate the result of surgical intervention in costoclavicular syndrome of a 38-year old man with clavicular nonunion after an operation.

BACKGROUND: To evaluate the effect of the balloon dilatation in tuberculous bronchial stenosis, we performed balloon dilatation in 13 cases which had airway obstruction in main bronchus with the impairment of pulmonary function. MATERIAL AND METHODS: Thirteen women with tuberculous bronchial stenosis(9cases: left main bronchus, 4 cases: right main bronchus) underwent fluoroscopically guided balloon dilatation under the local anesthesia. Among the these patient, 9 cases were active endobronchial tuberculosis, and 4 cases were inactive. Immediate and long term follow-up(average 15.6months) assessments were done focused on change on PFT. The increase of FVC or FEV1 more than 15% after the procedure was considered effective. Complications after dilatation were evaluated in all patients. RESULT: 1) There were an decrease of self-audible wheezing in 75%(6/8), improvement of dyspnea in 62.5%(5/8), improvement of cough and expectoration in 50%(3/6), and improvement of chest discomfort in 50%(l/2). 2) Significant improvement of PFT was noted in 42.9%(3/7) of which respiratory symptoms duration was below 6 months. But, significant improvement of PFT was noted in only 25% (1/4) of which respiratory symptoms duration was above 12 months. 3) Active stage was 69.2%(9/13) and inactive was 30.8%(4/13). There was an significant improvement of PFT in 44.4%(4/9) of active stage, but, only 25%(l/4) of inactive stage was improved. 4) In 61.5%(8/13), FVC and FEV1 were increased to 35.5%, and 22.2% at post-dilatation 7 days. After 1 month later, FVC and FEV1 were increased to 54.7%, and 31.8% in 5 cases(38.5%). 4 cases in which long-term follow-up(average 19.8months) was possible the improvement of FVC, and FEV1 were 30.5%, and 10.1%. . 5) Just after balloon dilatation therapy, transient leukocytosis or fever was noted in 30.8%(4/13), and blood-tinged sputum was noted in 30.8%(4/13). However, serious complication, such as pneumothorax, pneumomediastinum or mediastinitis, was not noted. CONCLUSION: We conclude that tuberculous bronchial stenosis, which is on active stage, and short dulation of respiratory symptoms was more effective on balloon dilatation than inactive stage or long duration of respiratory symptoms. Furthermore, balloon dilatation is easier, much less invasive and expensive than open surgery, and cryotherapy or photoresection. Because of these advantage, we think that balloon dilatation could be the first choice for treating bronchial stenosis and could be done at first in early stage if unresponsiveness with steroid therapy is observed.

Remnant gastric cancer is defined broadly as cancer that develops in the remnant stomach after the resection of nonmalignant or malignant lesions. Generally speaking, remnant gastric cancer is defined as its interval between previous gastrectomy and the detection of remnant gastric cancer must be over 10 years in the previous malignant or nonmalignant lesions. From Aug. 1988 to Dec. 1995, fifteen patients who were operated as remnant gastric cancer (broad definition) in Hanyang Universty Hospital was reviewed as follows. Sex distribution was 12 cases in male and 3 cases in female. Peak incidence of age was 5th and 6th decades.The T.N.M. staging was at first operation: benign disease in 6 cases, stage I in 4 cases, stage IIIa in 1 case, stage IIIb in 2 cases and unknown stage in 2 cases, and at 2nd operation; stage I in 3 cases,stage II in 1 case, stage IIIa in 2 cases, stage IIIb in 5 cases, stage IV in 4 cases. The interval between first and second operation was as follows : less than 5 years in 4 cases, 5 to 10 years in 2 cases, 10 to 15 years in 3 cases, and over 20 years in 6 cases. The procedure at first operation was Billroth II procedure, and the procedure at 2nd operation was as follows: total gastrectomy with Roux-en-Y esophagojejunostomy in 12 cases,total gastrectomy with loop esophagojejunostomy in 2 cases,dismentling partial gastrectomy with Roux-en-Y gastrojejunostomy in 1 case. In our opinion,early diagnosis of remnant carcinoma following gastric surgery by the endoscopic follow up and aggresive surgery are important to improve disease free interval and patient survival.

PURPOSE: To determine the effect of photodynamic therapy (PDT) on patients with chronic central serous chorioretinopahty (CSC). METHODS: This was a retrospective multicenter study. We collected demographic and ophthalmic data for patients with chronic CSC who were treated with PDT from 16 institutions in Korea. The best corrected visual acuity (BCVA), ophthalmoscopic finding and optical coherence tomography at baseline and follow-up visits were compared longitudinally. RESULTS: Sixty-five eyes of 65 patients were recruited. Males (51 patients, 78.5%) outnumbered females (14 patients, 21.5%). The mean age was 46.4+/-10.0 years of age (28~69). By 1 month, mean BCVA improved from 0.47 to 0.37 (logarithm of the minimum angle of resolution) (P <0.01). This BCVA increased throughout 6 months. Subretinal fluid resolved partially or completely in 89.1% of the patients. Central macular thickness (CMT) decreased from 303.4 to 168.7 micrometer. The amount of change in CMT after PDT was correlated to the female sex and prePDT CMT. At 3 months after PDT, the amount of change in BCVA was significantly related to that of change of CMT (p <0.05). Adverse events were reported in 4 cases, however, most were mild. CONCLUSIONS: PDT was effective and safe for treating chronic CSC.

PURPOSE: To evaluate the efficacy of photodynamic therapy (PDT) with verteporfin for polypoidal choroidal vasculopathy (PCV) in Korean patients. METHODS: Clinical data of patients who were treated with PDT for PCV and followed up for more than 6 months were collected from 14 hospitals around the country. The changes in the best corrected visual acuity, angiographic outcome, retinal thickness measured by optical coherence tomography (OCT), and adverse effects of treatment were evaluated. RESULTS: Eighty six patients (86 eyes) were recruited (male: 75.6%, age: 65.9+/-8.3 years, mean follow-up: 14.8+/-10.2 months). The mean logMAR visual acuity at baseline was 0.55+/-0.32 and did not show any statistically significant difference from the final mean logMAR visual acuity (0.53+/-0.54) (p=0.639). The mean treatment session number of PDT was 2+/-1.2. Visual acuity stabilized or improved in 70.9% of patients. Visual acuity improved by more than 2 lines in 33 eyes (38.4%) and worsened by more than 2 lines in 21 eyes (24.4%) of patients. Vascular leakage decreased in 62.5% of patients in fluorescein angiography and polypoidal lesions disappeared or were reduced in 57.3% of patients in indocyanine green angiography. There was no systemic adverse effect of PDT, but increased subretinal hemorrhage after PDT occurred in 10 eyes (11.6%). CONCLUSIONS: In polypoidal choroidal vasculopathy, photodynamic therapy with verteporfin is safe and effective for preserving visual acuity and reducing vascular leakage and retinal thickness.

Purpose:
The Korean Renal Cancer Study Group (KRoCS) provides consensus recommendations on the role of cytoreductive nephrectomy (CRN) in patients with metastatic renal cell carcinoma (mRCC).
Materials and Methods:
A group of mRCC experts from the Korean Urological Oncology Society convened at the 2021 KRoCS meeting on CRN for mRCC.
Results:
The consensus document was developed to address 4 questions related that were judged to be the most relevant to patient care: (1) Is there a role for CRN in patients planning targeted therapy? (2) Is there a role for CRN in patients planning immuno-oncology agents? (3) When is the optimal time of CRN in patients planning systemic treatment? (4) What is the ideal patient selection for CRN? The panelists have come up with following consensus. For mRCC patients, CRN should be considered only in those with IMDC (International Metastatic Renal Cell Carcinoma Database Consortium) favorable and intermediate risk disease, regardless of the systemic treatment plans. Timing of CRN should consider the risk group as well as the number of risk factors, but is generally recommended for after assessing the degree of response to initial systemic treatment. Patients with good performance status, limited metastatic burden on top of resectable primary tumor are candidates recommended for CRN with or without metastasectomy with priority.
Conclusions
In conclusion, there is still a role for CRN in the multimodality treatment of mRCC. Careful patient selection is of paramount importance. As the treatment landscape of mRCC continues to change, the role of CRN in the current immuno-oncology era will require more exploration.
