PURPOSE: This study was tried to evaluate the potential benefits of concurrent chemoradiation therapy (low dose daily cisplatin combined with split course radiation therapy) compared with conventional radiation therapy alone in stage III non-small cell lung cancer. The end points of analyses were response rate, overall survival, survival without locoregional failure, survival without distant metastasis, prognostic factors affecting survival and treatment related toxicities. MATERIAL AND METHODS: Between April 1992 and March 1994, 32 patients who had stage III non-small cell lung cancer were treated with concurrent chemoradiation therapy. Radiation therapy for 2 weeks (300cGy given 10 times up to 3000cGy) followed by a 3 weeks rest period and then radiation therapy for 2 more weeks (250cGy given 10 times up to 2500cGy) was combined with 6mg/M2 of cisplatin. Follow-up period ranged from 13 months to 48 months with median of 24 months. Historical control group consisted of 32 patients who had stage III non-small cell lung cancer were received conventionally fractionated (daily 170-200cGy) radiation therapy alone. Total radiation dose ranged from 5580cGy to 7000cGy with median of 5940 cGy. Follow-up period ranged from 36 months to 105 months with median of 62 months. RESULTS: Complete reponse rate was higher in chemoradiation therapy (CRT) group than radiation therapy (RT) group (18.8% vs. 6.3%). CRT group showed lower in-field failure rate compared with RT group (25% vs. 47%). The overall survival rate had no significant differences in between CRT group and RT group (17.5% vs. 9.4% at 2 years). The survival without locoregional failure (16.5% vs. 5.3% at 2 years) and survival without distant metastasis (17% vs. 4.6% at 2 years) also had no significant differences. In subgroup analyses for patients with good performance status (Karnofsky performance scale 80), CRT group showed significantly higher overall survival rate compared with RT group (62.5% vs. 15.6% at 2 years). The prognostic factors affecting survival rate were performance status and pathologic subtype (squamous cell cancer vs. nonsquamous cell cancer) in CRT group. In RT alone group, performance status and stage (IIIa vs IIIb) were identified as a prognostic factors. RTOG/EORTC grade 2-3 nausea and vomiting (22% vs. 6%) and bone marrow toxicities (25% vs. 15.6%) were significantly higher in CRT group compared with RT alone group. The incidence of RTOG/EORTC grade 3-4 pulmonary toxicity had no significant differences in between CRT group and RT group (16% vs. 6%). The incidence of WHO grade 3-4 pulmonary fibrosis also had no significant differences in both group (38% vs. 25%). In analyses for relationship of field size and pulmonary toxicity, the patients who treated with field size beyond 200cm2 had significantly higher rates of pulmonary toxicities. CONCLUSION: The CRT group showed significantly higher local control rate than RT group. There were no significant differences of survival rate in between two groups. The subgroup of patients who had good performance status showed higher overall survival rate in CRT group than RT group. In spite of higher incidence of acute toxicities with concurrent chemoradiation therapy, the survival gain in subgroup of patients with good performance status were encouraging. CRT group showed higher rate of early death within 1 year, higher 2 year survival rate compared with RT group. Therefore, to evaluate the accurate effect on survival of concurrent chemoradiation therapy, systematic follow-up for long term survivors are needed.

PURPOSE: Atopic dermatitis is a chronic, inflammatory skin disease characterized by intense pruritus and an immunologic profile consistent with allergic disease. It is associated with increased eosinophil and IgE level and decreased INF-gamma production. We describe the result of a treatment with INF-gammaand assess the clinical, immunologic, and laboratory data of 12 patients with atopic dermatitis. METHODS: Twelve patients were treated for 12 weeks with 2x106 units/m2 INF-gamma by subcutaneous injection. General hematologic tests were done, and total eosinophil counts, eosinophil fractions, neutrophil fractions, and IgE levels were measured before the treatment, 2 weeks after the treatment, 12 weeks after the treatment serially. We also followed up the patients for 12 weeks after discontinuing INF-gammatherapy. RESULTS: All patients showed clinically significant improvement after 12 weeks of the systemic INF-gammatherapy. There was no clinical aggravation during the therapy period and the follow-up 4 weeks without the therapy. But the recurrence rate in the 12 weeks after discontinuing the therapy was about 40%. Eosinophil counts and eosinophil fractions were significantly decreased after the therapy. And, eosinophil counts and eosinophil fractions were increased in clinically aggravated patients during the 12 weeks of off-therapy. CONCLUSION: We conclude that INF-gammais an effective therapy in atopic dermatitis without significant side effects. The eosinophil counts and eosinophil fractions were decreased during the INF-gamma therapy, and increased in clinically aggravated patients after the off-therapy. There was no aggravation during the therapy. But 5 patients were clinically aggravated during the 12 weeks of off-therapy. Further studies for a long-term maintenance therapy and its side effect might be needed in chronic atopic dermatitis.

Focal fatty change of the liver is a nodular lesion which is a rarely described and poorly characterized entity. The hepatic nodule measured 1.4cm at its maximum diameter, was subcapsular in location and occurred adjacent to the falciform ligament. Microscopically it was composed of hepatic tissue with a preserved lobular architecture. The central venous structures and portal tracts with their triads were regularly placed. The cytoplasm of almost all of the hepatocytes within the nodule was replaced by macrovesicular fat vacuoles with the nuclei displaced. Several large abnormal vessels were found at the margin of the nodule. The nodule was discovered incidentally on postmortem examination of a female infant who proved, at autopsy, to have multiple cardiac anomalies and bronchopneumonia. The possible inadequate local tissue perfusion due to abnormal intrahepatic vessels at this particular location could be augmented by multiple cardiac anomalies culminating in focal ischemia and focal fatty change. When encountered in surgery or on gross examination, it could be confused with other space occupying lesions such as liver cell adenoma, abscess and metastatic lesions.

PURPOSE: To describe the early experience of analyzing variations and time trends in bladder volume of the rectal cancer patients who received bladder ultrasound scan. MATERIALS AND METHODS: We identified 20 consecutive rectal cancer patients who received whole pelvic radiotherapy (RT) and bladder ultrasound scan between February and April 2012. Before simulation and during the entire course of treatment, patients were scanned with portable automated ultrasonic bladder scanner, 5 times consecutively, and the median value was reported. Then a radiation oncologist contoured the bladder inner wall shown on simulation computed tomography (CT) and calculated its volume. RESULTS: Before simulation, the median bladder volume measured using simulation CT and bladder ultrasound scan was 427 mL (range, 74 to 1,172 mL) and 417 mL (range, 147 to 1,245 mL), respectively. There was strong linear correlation (R = 0.93, p < 0.001) between the two results. During the course of treatment, there were wide variations in the bladder volume and every time, measurements were below the baseline with statistical significance (12/16). At 6 weeks after RT, the median volume was reduced by 59.3% to 175 mL. Compared to the baseline, bladder volume was reduced by 38% or 161 mL on average every week for 6 weeks. CONCLUSION: To our knowledge, this study is the first to prove that there are bladder volume variations and a reduction in bladder volume in rectal cancer patients. Moreover, our results will serve as the basis for implementation of bladder training to patients receiving RT with full bladder.

The globus symptom is a condition in which a patient, often middle aged women, complains of a lump andchocking sensation in the throat, Functional disturbance of the cricopharyngeal muscle, rendering it incapable ofrelaxing during swallowing, has long been recognized as a cause of globus symptom and dysphagia. We wanted to findout how often and to what extent distrubed relaxation of the cricopharyngeal muscle can be seen in patients withglobus symptom with routine examination and video esophagogram. The results were as follows: 1. Male : femaleratio was 1:2.4. 2. Globus symptom was most frequent in the age group between 30-39 of female. 3. Organic lesionswere seen in 43.6%(24 Pts) of globus patients. 4. Cricopharyngeal muscle was visualized in 29.1%(16Pts), esophageal diverticulum in 3.6%(2 Pts) and degenerative spondylosis in 3.6%(2 Pts). 5. Incidence of visualizationof cricopharyngeal muscle were higher in male group (50%) than female one (20.5%). 6. Cricopharyngeal muscle wasmost frequently visualized on early swallowing phase(12/16 Pts).

OBJECTIVE: This study was performed to determine the relations of glycosylated hemoglobin (HbA1c) and parameters of nerve conduction study (NCS) in diabetic peripheral polyneuropathy patients. METHOD: Prospectively, total 40 patients with non-insulin dependent diabetes mellitus were included in the study. NCS was performed on median, ulnar, posterior tibial, deep peroneal, superficial peroneal, and sural nerves. Distal latency and conduction velocity (CV) of compound muscle action potential (CMAP), distal latency and amplitude of sensory nerve action potential (SNAP) were used as parameters of NCS. Multiple linear regression analysis were used to analyze the relations of HbA1c and parameters of NCS, after adjustment for age, height, weight, and disease duration of diabetes mellitus. RESULTS: HbA1c level had an inverse relation to CV of median motor nerve (beta= 1.272, p<0.01), ulnar motor nerve (beta= 1.287, p<0.01), posterior tibial nerve (beta= 0.982, p<0.05), and deep peroneal nerve (beta= 1.449, p<0.05). CONCLUSION: This study indicates that HbA1c level was inversely related to motor nerve CV, and that sustained hyperglycemia may be involved in demyelination of motor nerves. Analysis of motor nerve CV related to HbA1c is expected to be useful in the follow-up or efficacy study of diabetes mellitus neuropathy as baseline data.

OBJECTIVE: To evaluate the efficacy of epidural injections of hypertonic saline, steroid and local anesthetics in patients with low back pain and sciatica. METHOD: Retrospective study of 325 patients with low back pain and sciatica. Group I, 261 patients, were treated with epidural injection of steroid (Depo-medrol ) weekly for 2 weeks and local anesthetics (lidocaine and bupivacaine) daily via epidural catheter. Group II, 64 patients, were treated with epidural injection of hypertonic saline for three successive days and same method of group I via epidural catheter. The efficacy was assessed with Visual Analog Scale (VAS) on the day of pre- and post- (2weeks later) epidural injection. RESULTS: (1) VAS score changes from pre- to post-epidural injections were from 6.1+/-3.6 to 3.6+/-1.8 (p<0.05) in Group I and from 6.2+/-1.6 to 2.6+/-1.4 (p<0.05) in Group II. (2) VAS score decrease of Group II was more than that of Group I (p<0.05). CONCLUSION: Epidural injections of hypertonic saline, steroid and local anesthetics are effective for patients with low back pain and sciatica in the short term, and more effective than that of steroid and local anesthetics, but prospective long-term follow up studies will be necessary in the future.

PURPOSE: Recently, there are many good reports on the arthroscopic management of tibial condylar fractures. But, it may be appropriate for selected tibial condylar fractures and also needs a skilled technique. So we report the results of the tibial condylar fractures treated by the arthroscopy and limited percutaneous fixation or the arthroscopic-assisted management with conventional internal fixation without arthrotomy. MATERIALS AND METHODS: From June 1996 to December 1997, we treated 22 cases of the tibial condy- lar fractures including relatively comminuted one and analysed the results of patients who have been observed at least 1 year with Porters knee evaluation criteria. RESULTS: In 18 out of 22 cases, the results were Acceptable on symptoms(excellent 3, good 15, fair 4), in 18, on function(excellent 10, good 8, fair 3), in 21, on appearance(excellent 12, good 9, fair 1) and in 20, on radiographic appearance(excellent 11, good 9, fair 2). Overall results were Acceptable in 18 cases(82%) and Unacceptable in 4 cases(18%). CONCLUSION: The arthroscopic-assisted management with conventional internal fixation without arthrotomy can be the recommendable treatment for the tibial condylar fractures, including relatively comminuted one, without complications.
