1.Predictors of radiation pneumonitis and pulmonary function changes after concurrent chemoradiotherapy of non-small cell lung cancer.
Radiation Oncology Journal 2013;31(1):34-40
PURPOSE: To evaluate the predictive factors of radiation pneumonitis (RP) and associated changes in pulmonary function after definitive concurrent chemoradiotherapy (CCRT) in patients with non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: Medical records of 60 patients with NSCLC who received definitive CCRT were retrospectively reviewed. Dose volumetric (DV) parameters, clinical factors, and pulmonary function test (PFT) data were analyzed. RP was graded according to the CTCAE ver. 4.0. Percentage of lung volume that received a dose of threshold (Vdose) and mean lung dose (MLD) were analyzed for potential DV predictors. PFT changes were calculated as the difference between pre-RT and post-RT values at 3, 6, and 12 months after RT. RESULTS: Twenty-two patients (37%) developed grade > or =2 RP. Among clinical factors, tumor location in lower lobe was associated with RP. Among the DV parameters, only MLD >15 Gy was associated with grade > or =2 RP. There were statistically significant decreases in PFT at all points compared with pre-RT values in grade > or =2 RP group. MLD was associated with forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) changes at 6 and 12 months. V10 was associated with FVC changes at 12 months. V20 and V30 were associated with FEV1 changes at 6 months and FVC changes at 12 months. CONCLUSION: After definitive CCRT in patients with NSCLC, MLD >15 Gy and lower lobe tumor location were predictors of grade > or =2 RP. Pulmonary functions were decreased after CCRT and the magnitude of changes was associated with DV parameters.

The occurrence of a lipoma-like condition associated with trauma would tend to be regarded as a subset of or a separate entity from ordinary lipoma. We report herein a case of traumatic Lpoma occuring on the dorsum of the left hand. The patient was a 46-year-old male, who had struck his left hand against a window about two months previously and noted casually an asymptomatic, firm, dermal lesion at the site of injury. On gross examination, the enucleated nodule was a smooth-surfaced, yellow fatty mass measuring 0.3 × 0.5 × 0.3cm which looked like a kernel of corn. Microscopic examination revealed encapsulated mature fat consistent with lipoma.

Leiomyoma is one of the rarest solid tumor of the ovary. Approximately 50 cases have been published to date. However, most reported leiomyoma of the ovaries were small and rarely induced serious symptoms. We report a case of ovarian leiomyoma in 57-year-old woman which has been experienced in our haspital with brief review of literature.

To Evaluate the clinical characteristics of childhood-onset systemic lupus erythemoatosus (SLE) and analyse the factors related to outcome of renal function in lupus nephritis, we reviewed medical records of 18 cases of SLF diagnosed at the Department of Pediatrics. Pusan National University Hospital from January 1981 to December 1990. The results were as follow: 1)Male to female ratio was 1:2.6. 2) Nephropathy was the most common initial impression, and 8 cases were diagnosed as SLE at first. 3) The clinical menifestation. was ANA (+), malar rash, renal disorder, hematologic disorder in frequency. 4) Diffuse proliferative lupus nephritis was the most common in renal histopathologic studies. 5) Among the follow-up cases, active lupus was 39%, remission was 28%. 6) As factors related to outcome of lupus nephrits were, hypertension and proteinuria were siginificant statistically.

A 59-year-old male farmer, an alcohol addict, has experienced repeated bullous skin lesions on the erythematous base over the exposed areas of tbe skin, especially on the face and hands, after sun-light exposure. The face showed hyperpigmenation, hypertrichosis and sclerodermoid changes. And also there were hypopigmented scars on the dorsum of the hands and cIaw-1ike fingers. Characteristic laboratory findings were as follows: Urine appeared portwine color and fluoresced under the Woods Iight. A 24-hour urine collection contamed 4l32ug of uroporphyrin and 3815ug of corproporphyrin. BSP retention(7% in 45 Min.) was increased, and A/G ratio(0. 8:1) was inverted. Gamma globulin(44, 9%) was markedly increased on serum electrophoresis. Roentgenograms revealed minimal tuberculosis on the chest P-A and superficial gastritis on the upper G-I series. Electrocardiogram showed left ventricular hypertrophy. Pathological findings of the specimen obtained from sclerodermoid lesion of the forehead revealed hypermelanosis in the basal cell layer and amorphous, basophilic collagen degeneration in the upper dermis, on the other hand loss of sinusoids due to swelling of hepatocytes and chomic inflammatory cell infiltrate in the interlobular septa were noticed on the specimen taken from the liver. For treatment, phlebotomy and metabolic alkalinization were trjed.

The objective of this study is to examine the correlation between the tolylene concentration in the work environment of organic solvents and the concentration of hippuric acid in urine of workers exposed toluene, and to acquire the fundamental materials of workers' health care and to assist the assessment of the biological permissible exposure limit. The control groups are 72 workers who had never been exposed to toluene and the case groups are 101 workers who had been exposed to toluene. This study was conducted to examine the correlation between the concentration of toluene in work environment and workers' hippuric acid concentration, to investigate the complaint difference of subjective symptoms by means of questionnaire, between the case groups and control groups. The results and conclusions are as follows: 1) The highest mean concentration of toluene in the air is 544.13+/-7.75 ppm in the Printing Department of mixing organic solvents. The concentrations of the others are 463.27+/-5.24 ppm in Department of mixture for organic solvents, and 393.56+/-45.69 ppm in the Printing Department(1), and 248.38+/-45.16 ppm in the Printing Department(2), and 159.38+/-18.51 ppm in the Printing Department(3). 2) The highest mean concentration of hippuric acid in urine is 6034.84+/-1298.35 mg/l in the Printing Department with mixing organic solvents. The concentrations of the others are 4798.44+/-784.53 mg/l in Department of mixture of organic solvents, and 2883.06+/-701.90 mg/l in the Printing Department(1), and 1449.98+/-905.19 mg/l in the Printing Department(2), and 598.52+/-299.43 mg/l in the Printing Department(3). 3) As the toluene concentration in the work environment becomes higher, the concentration of hippuric acid in urine also becomes higher. It is found that the coefficient of correlation between toluene concentration and the concentration of hippuric acid are positive (r=0.868, Y=7.18X+349.57). 4) It is found that the case groups complain of much more subjective symptoms than the control groups.

Normal human B cells produce autocrine growth factor in response to Staphylococcus aureus Cowan I strain (SAC). However, the functional role and molecular nature of the B cell derived-B cell growth factor (B-BCGF) are largely unknown. We have tried to investigate the nature of B-BCGF using mAb for several years. We report here that B- BCGF is capable of binding to hemoglobin (Hb). The concentrated culture supernatant from tonsillar B cells stimulated with SAC for 24 h was loaded into the fast protein liquid chromatography and ion-exchange chromatography. The peak with BCGF activity was shown to have a M.W. of 16-18 Kda in polyacrylamide gel electrophoresis followed by silver stain. Amino acid sequence of the fraction was found to identical to human hemoglobin (Hb) by more than 85%. However, Hb itself had no BCGF activity. The presence of Hb in culture supernatant was due to the contamination of SRBC during B cell purification. SRSC were completely removed from B cells by percoll-gradient centrifugation and B cells were stimulated with SAC and exogenous Hb was added to the cultures. The Hb fraction from FPLC again showed a BCGF activity. These data strongly suggested that BCGF binds to Hb. We confirmed this in dot blot as well as Western blot. The M.W of Hb-binding BCGF was 20 Kda. This information may provide a rapid progress in research of BCGF.
