Purpose: Oligoprogressive lesions are observed in a subset of patients who progress to castration-resistant prostate cancer (CRPC), while other lesions remain controlled by systemic therapy. This study evaluates the impact of progression-directed therapy (PDT) on these oligoprogressive lesions. Materials and Methods: This retrospective study included 40 patients diagnosed with oligoprogressive CRPC. PDT was performed for treating all progressive sites using radiotherapy. Fifteen patients received PDT using radiotherapy for all progressive sites (PDT group) while 25 had additional first-line systemic treatments (non-PDT group). In PDT group, 7 patients underwent PDT and unchanged systemic therapy (PDT-A group) and 8 patients underwent PDT with additional new line of systemic therapy on CRPC (PDT-B group). The Kaplan–Meier method was used to assess treatment outcomes. Results: The prostate specific antigen (PSA) nadir was significantly lower in PDT group compare to non-PDT group (p=0.007). A 50% PSA decline and complete PSA decline were observed in 13 patients (86.7%) and 10 patients (66.7%) of PDT group and in 18 patients (72.0%) and 11 patients (44.0%) of non-PDT group, respectively. The PSA-progression free survival of PDT-B group was significantly longer than non-PDT group. The median time to failure of first-line systemic therapy on CRPC was 30.2 months in patients in PDT group and 14.9 months in non-PDT group (p=0.014). PDT-B group showed a significantly longer time to progression than non-PDT group (p=0.025). Minimal PDT-related adverse events were observed. Conclusions PDT can delay progression of disease and enhance treatment efficacy with acceptable tolerability in oligoprogressive CRPC.

Purpose: We prospectively compared the diagnostic accuracy of kidney dynamic computed tomography (KDCT), magnetic resonance imaging (MRI), and contrast-enhanced ultrasonography (CEUS) for the assessment of small renal mass (SRM) (≤4 cm). Materials and Methods: Seventy-six patients with SRM (mean age, 58.4±13.1 years) who underwent renal biopsy (n=11) or nephrectomy (partial or radical) (n=65) were enrolled. All patients underwent KDCT, MRI, and CEUS before renal biopsy or nephrectomy. Results: The mean maximal tumor size was 21.0±9.8 mm. The mean R.E.N.A.L nephrometry score was 7.0±1.7. Fifty-six patients had renal cell carcinoma (RCC) (clear cell, 42; papillary, 7; chromophobe, 5; succinate dehydrogenase deficient, 1; unspecified RCC, 1). Twenty patients had a benign tumor (angiomyolipoma, 11; oncocytoma, 3; others, 6). Clinicopathologic variables were comparable in RCC and benign groups. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of KDCT were 89.3%, 10.0%, 73.5%, and 25.0%, respectively. The sensitivity, specificity, PPV, and NPV of MRI were 89.3%, 10.0%, 73.5%, and 25.0%, respectively. The sensitivity, specificity, PPV, and NPV of CEUS were 85.7%, 50.0%, 82.8%, and 55.6%, respectively. The diagnostic accuracy of KDCT, MRI, and CEUS were 68.4%, 68.4%, and 76.3%, respectively. In a subgroup analysis based on clinical tumor size of 10 mm and 20 mm, CEUS also showed the highest diagnostic accuracy. Conclusions CEUS had the highest specificity, PPV, and NPV and may help improve the assessment of SRM.

BACKGROUND: Since the bioavailability of itraconazole capsule is influenced by patients gastric acidity, it results in treatment failure due to its low dissolution and subsequent low absorption when administered in fasting. Itraconazole Melt-Extrusion tablet has been lately developed in order to improve its dissolution profile. It is the first clinical study to evaluate the efficacy and safety of itraconazole Melt-Extrusion tablet in Korea. OBJECTIVE: This study was conducted to evaluate the efficacy and safety of itraconazole melt-extrusion tablet 400mg daily for 1 week(pulse therapy) for hyperkeratotic type of tinea pedis and manus. METHODS: A clinical and mycological investigation was made of 812 outpatients with hyperkeratotic type of tinea pedis and/or tinea manus who had visited at 52 general hospitals under the lead of the Korean Dermatological Association from June to December, 1998. Patients confirmed by clinically and microscopically as hyperkeratotic type of tinea pedis and/or tinea manus were administered 2 tablets twice a day for one week and followed up for 8 weeks from the start of the medication. RESULTS: The results were summarized as follows; 1. Clinical symptoms of hyperkeratotic type of tinea pedis and/or tinea mauns were significantly improved at the end of study, week 8(p<0.001). 2. Clinical response rate, defined as more than 50% decrease of the sum of the clinical symptom scores, was 79.3%(512/646). 3. Mycological cure rate, dafined as both culture and KOH negative at week 8, was 78.2%(244 /312). 4. 40(5.5%) patients, of the 727 patients evaluable for drug safety evaluation, were reported to have adverse event. CONCLUSION: Itraconazole Melt-Extrusion tablet 400mg/day for 1 week (pulse therapy) is effective and safe in the treatment of hyperkeratotic type of tinea pedis and/or tinea manus.

This study was performed to evaluate the factors influencing the Quality of Life(QOL) in hemodialysis patients. Authors surveyed and analyzed the questionnaires about social characteristics, symptom, social support, satisfaction with life and quality of life. With these questionnaires, authors compared the hemodialysis patients(N=240, >6 month with hemodialysis) with the control group(N=240). Additionally authors eva- luated the anemia state, nutritional state and dialysis effect, and then analyzed the correlation between these laboratory findings and quality of life in hemodialysis patients. The results were as follows ; 1) The mean age of control group was 33.4 +/- 8.2 yrs, and the patients group was 48.812yrs. 2) Of 294 patients, 73 had the religion(75.2%), 173 had studied above high school(58.8%), 211 were married(71.8%), and 94 were homemaker(3296). Economically, 130 of 294 patients(44.2M) were the middle classes. The patients without occupation were 121 of 294 patients(41.2M), while those with occupation were 77(26.1%) and remainder were housemaker. The patients with medical insurance were 59.9%, those with 1st Medicaid were 22.4%, and those with 2nd Medicaid were 17%. 3) The causes of ESRD were CGN(29.5%), DM (22.3%), etc. Total duration of hemodialysis was 51.4 43.8 months in average, and weekly hemodialysis time was 11.541.98 hours in average. Average BMI was 20.6 +/- 2.79, and in 236 of 294 patients(80.1%), EPO was injected. Of all the complication, 96(32.9%) was cardiovascular problem. Iron storage state was relatively good in all the patients, and the mean level of PTH-i was 174.3 +/- 307.9pg/dl, hemoglobin 8.5 +/- 1.3g/dl, cholesterol 161.536.6mg/dl, total protein 6.60.5g/dl, albumin 3.960.4g/dl. The URR was 65.36.9%, and KtV was 1.3 +/- 0.3. The comparison about laboratory finding between male and female was as followed; Hb. and albumin level was signifi- cantly higher in male compared with female patients, and cholesterol, URR and Kt/V was significantly higher in female than in male. 4) The result of statistic analysis about several variables and Questionnaires. (1) The subjective and objective instrument about QOL showed positive correlation, and the QOL was correlated positively to symptom, physical health state and social support. (2) Of social characteristics, the direct influencing factors for QOL were occupation, economic state, marriage state, and educational state, whereas in- direct factors were a fee for medical treatment and social support. In clinical and laboratory characteristics, the significant factors were age, DM, symptoms, albumin, pre-dialytic creatinine, sodium and calcium. The effect of dialysis did not correlate with QOL. In conclusion, to increase QOL in dialysis pa- tients, all of the community, family, and medical team should make an effort. Firsty, the concern and the support of the community about the dialysis patients should be promoted in social welfare and the opportunity of employment. Secondly, the patients should promote the self-reliance and self- efficacy to take a share of their role in the community and a family by their own efforts. Lastly, the medical team should make an effort to decrease the symptom, to correct the anemia and malnutrition, to treat the complication, and to promote the physical activity. Through these efforts, the health of patients will be elevated. Elevation of the patient's health will increase the possibility of employment and self-reliance, and subsequently will increase the economics. If so, the burden of a fee for the medical treatment will be reduced. Additionally, if social and familial support increase, the QOL of the dialysis patients will be better.

It has been known that dilated cardiomyopathy(DCM) is characterized by systolic dysfunction of left ventricle(LV), but there were few studies about correlation between LV systolic function, diameter and diastolic function measured by echocardiography and radionuclide ventriculography(RVG) The purpose of this study is to evaluate LV systolic and diastolic function as well as RV function using regional ejection fraction and functional images by RVG in 17 patients with DCM and to compare these variables with echocardiographic data. The results are as follows : 1) DCM showed diffuse systolic and diastolic dysfunction of LV. The systolic impairment is accounted for the diastolic impairment in DCM. 2) The increased standard deviation of phase angle of left ventricle(LVSDph) revealed LV asynchronous contraction in DCM. 3) LVSDph showed significant correlations with other RVG parameters such as LV ejection fraction, and peak ejection rate, peak filling rate and also with LV systolic and diastolic diameter measured by echocardiography. It is concluded that LVSDph may be useful in evaluation of LV systolic and diastolic function in patients with DCM as well as LV asynchronous contraction.

Bone grafts are an integral and important aspect of craniofacial reconstruction. Rips, tibia, and iliac bone have traditionally used as donor site but each of these has various problems, however using to the calvarial bone as a donor site has several advantage. These are as follows; there are abundance of material, easy to reach the donor site through coronal incision, minimal pain of donor area, less functional inability, shorter hospitalization, no need of immobilization, hidden scar at donor site, no secondary deformity and appropriate curvature obtained properly selected. From March to December 1987, we experienced three cases of autogenous calvarial bone graft such as congenital saddle nose deformity, fibrous dysplasia on the right side frontal bone, and deviated nose. The results were very excellent without any significant complication. The detail technique of autogenous calvarial bone graft and its advantages compared with the traditional methods of bone grafts are discussed.
