Orbital mesenchymal chondrosarcoma, first described by Luis et. al in 1971, is a very rare tumor of characteristic histologic features. A 21-year-woman was admitted with a 4-month histoiry of rapidly progressive proptosis and visual disturbance. Right orbital exenteration was performed under the clinical diagnosis of orbital calcifying tumor. Grossly, the tumor presented as a multibloblated, circumscribed mass that measures 5.5 cm in the greatest dimentsion. Cut sections resembled ordinary chonrosarcoma. Microscopically, the tumor was composed of undifferentiated mesenchymal cells, interspersed nodules of well differentated cartilagenous tissue, areas of gradual transition from undifferentiated mesenchymal cells to cartilage, and hemangiopericytoma-like areas. A brief summary of the histopathological aspect of this tumor and a review of literature are presented.

2.Clinical Study to the Problem of Intestinal Gas for Intravenous Urography.
Korean Journal of Urology 1979;20(4):368-372
Intravenous urography is very important in the detection of pathological conditions of the urinary tract, but the presence of intestinal gas shadows may be very confusing in the interpretation of urograms. There is considerable difference of opinion regarding the desirability of preparing patients for excretory urography. we obtained clinical impression and statistical results that intestinal gas was increased with prolonged duration after last diarrhea, also with sleeping after last diarrhea. So we attempted one new method of preparation in which employed 30cc, of castor oil for catharsis two times at night before examination and next morning 6:00 a. m. and result was compared with other methods. A total of 300 cases, for the most in-patients, consisted of 6 groups, were studied in this report. All patients had nothing by mouth after midnight until the X-rays were completed and pyelograms usually were taken in the morning. Following methods of preparation were studied. Group 1 : 60 cc. castor oil at bed time. Group 2 : 60 cc. castor oil at 4:00 a. m. Group 3 : 30 cc. castor oil at bed time and 30 cc. at 6:00 a. m. Group 4 : 60 cc. castor oil at bed time and enema in the morning. Group 5 : No cathartics and enema. Group 6 : Dulcolax 2 tablets at bed time. The X-ray films were graded as A) excellent B) good C) fair D) poor by three or more examiners. Group 3. afforded best result. We believed that result was due to prevention of intestinal fermentation by ingestion of castor oil at bed time and passage of swallowed air before X-ray examination by repeated ingestion at 6:00 a. m. A larger series of cases over a longer period of time, for more accurate statistical study, is warranted.

Vibrio vulnificus causes rapid progressing fulminant infections in susceptible individuals, especially those with elevated serum iron levels. This ferrophilic bacterium can directly acquire iron from heme-containing proteins, such as, hemoglobin, via its heme receptor protein HupA. This study was undertaken to determine the roles of cyclic AMP-receptor protein (Crp) as an activator and of ferric uptake regulator (Fur) as a repressor in regulating hupA expression at various iron and glucose concentrations. Under severely iron-deficient conditions, hupA expression in the absence of Crp was induced albeit at low levels and repressed by the addition of iron. In contrast, hupA expression in the presence of Crp was increased by the addition of iron. Under moderately iron-deficient and iron-sufficient conditions, iron addition repressed hupA expression in the presence of Fur, but not in the absence of Fur. Glucose addition repressed hupA expression in the presence of Fur but not in the absence of Fur. Furthermore, a mutation in cyaA encoding adenylate cyclase required for cAMP synthesis hupA expression, and this repression was prevented by the exogenous addition of cAMP. These results indicate that hupA expression is under the coordinate control of cAMP or Crp, which responds to glucose availability, and of Fur, which responds to iron availability, and that Crp is not essential for the constitutional expression of hupA, but is required for the optimal expression of hupA, whereas Fur is essential for the prevention of hupA over-expression.

Central hypoventilation syndrome is a rare and fatal condition resulting from various central nervous system disorders that is characterized by a failure of automatic breathing. We report a case of central hypoventilation syndrome following posterior circulation stroke whose pulmonary function was improved by respiratory rehabilitation. A 59-year-old woman with a history of hemorrhagic stroke of the bilateral cerebellum was hospitalized due to pneumonia. A portable ventilator was applied via tracheostomy, recurrent episodes of apnea and hypercapnia impeded weaning. A respiratory rehabilitation program including chest wall range of motion exercise, air stacking exercise, neuromuscular electrical stimulation (NMES) on abdominal muscles, upper extremity ergometer, locomotor training, high-frequency chest wall oscillator, mechanical insufflation, and exsufflation was employed, as spirometry showed a severe restrictive pattern. A spontaneous breathing trial was started, and a portable ventilator was applied for 8 hours, only during nighttime, to prevent sudden apneic event. After 4 weeks of treatment, follow-up spirometry showed much improved respiratory parameters. This case suggests that respiratory rehabilitation can improve pulmonary function parameters and quality of life in central hypoventilation syndrome.

PURPOSE: The purpose of our study is to evaluate the plain radiographic features of pulmonary tuberculosis in adult diabetic patients compared with those in patients without any underlying diseases. MATERIALS AND METHODS: We analyzed the chest PA and lateral views of 100 patients having active pulmonary tuberculosis;40 patients had diabetes mellitus and 60 patients had no other underlying diseases. images were assesed for anatomical distributions, extents of lesions, size and number of cavity and patterns radiographic findings. RESULTS: Diabetic tuberculosis had higher prevalence and wider involvement of unusual segments for the tuberculosis such as anterior segment, lingular segment of upper lobe and basal segment of the lower lobe, and they showed the tendency of having more cavities than those who had no other underlying diseases, but there were no meaningful differences in the cavity size between the two groups. CONCLUSION: Pulmonary tuberculosis in diabetic patients tends to have wider extent with unusual segmental involvement and multiple cavities than in the patients who had no other underlying diseases.

OBJECTIVE: To identify the prevalence of lumbar scoliosis in breast cancer patients and to investigate the potential risk factors of lumbar scoliosis. METHODS: A retrospective chart review was performed in breast cancer patients aged more than 40 years who underwent dual energy X-ray absorptiometry (DEXA) scanning between January 2014 and December 2014. We divided the patients into control and experimental groups in order to investigate the influence of breast cancer treatment. The curvature of the lumbar spine was measured by using the Cobb method on a DEXA scan. Scoliosis was defined by the presence of a curvature 10° or larger. The variables, including age, bone mineral density (BMD), body mass index (BMI), and breast cancer treatments, were also obtained from the medical chart. Prevalence of lumbar scoliosis was evaluated, and it was compared between the two groups. The relationships between lumbar scoliosis and these variables were also investigated. RESULTS: Lumbar scoliosis was present in 16 out of our 652 breast cancer patients. There was no difference in the prevalence of lumbar scoliosis between the control group (7/316) and the experimental group (9/336) (p=0.70). According to the logistic regression analysis, lumbar scoliosis had no significant association with operation, chemotherapy, hormone therapy, BMI, and BMD (p>0.05). However, age showed a significant relationship with prevalence of lumbar scoliosis (p<0.001; odds ratio, 1.11; 95% confidence interval, 1.054–1.170). CONCLUSION: Prevalence of lumbar scoliosis in patients with breast cancer was 2.45%. Lumbar scoliosis had no association with breast cancer treatments, BMD, and BMI. Age was the only factor related to the prevalence of lumbar scoliosis.

This study was designed to investigate the effects of polyamines on mechanical contraction and voltage-dependent calcium current (VDCC) of guinea-pig gastric smooth muscle. Mechanical contraction and calcium channel current (I(Ba)) were recorded by isometric tension recording and whole-cell patch clamp technique. Spermine, spermidine and putrescine inhibited spontaneous contraction of the gastric smooth muscle in a concentration-dependent manner. Spermine (2 mM) reduced high K+ (50 mM)-induced contraction to 16+/-6.4% of the control (n=9), and significantly inhibited I(Ba) in a reversible manner (p<0.05; IC50=0.8 mM). Pre- and post-treatment of tissue with spermine (2-5 mM, n=10) also inhibited acetylcholine (10 micrometer)-induced phasic contraction to 5+/-6.4% of the control. Inhibitory effect of spermine on I(Ba) was observed at a wide range of test potentials of current/voltage (I/V) relationship (p<0.05), and steady-state activation of I(Ba) was shifted to the right by spermine (p<0.05). Spermidine and putrescine (1 mM each) also inhibited I(Ba) to 51+/-5.7% and 81+/-5.3% of the control, respectively. And putrescine (1 mM) inhibited I(Ba) at whole tested potentials (p<0.05) without significant change of kinetics (p<0.05). Finally, 5 mM putrescine also inhibited high K+ -induced contraction to 53+/-7.1% of the control (n=4). These findings suggest that polyamines inhibit contractions of guinea-pig gastric smooth muscle via inhibition of VDCC.

PURPOSE: We purpose to determine the correlation of HER-2/neu and paxillin expression in ductal carcinoma in situ (DCIS), invasive ductal carcinoma with ductal carcinoma in situ (IDC with DCIS) and mucinous carcinoma. METHODS: To evaluate the expression of HER-2/neu and paxillin, the immunohistochemical staining was performed for 13 cases of DCIS, 13 cases of IDC with DCIS and 6 cases of mucinous carcinoma. RESULTS: The DCIS and IDC were associated with infiltration of the inflammatory cells, especially in the comedo type and solid type of tumor. In cases with infiltration of the inflammatory cells, HER-2/neu and paxillin were strongly expressed. When comparing the expression level of HER-2/neu from adjacent normal tissue between DCIS and IDC with DCIS, expression of HER-2/neu was similar to that of normal tissue adjacent to DCIS. However, in the adjoining normal ductal epithelial cells, paxillin was highly expressed in cells of all of the tumor types, and especially for IDC with DCIS. HER-2/neu and paxillin were not expressed in mucinous carcinoma cells in all cases. CONCLUSION: HER-2/neu in the DCIS and IDC with infiltration of inflammatory cells shows higher expression than non-inflammatory DCIS and IDC. If normal duct epithelial cells show a high level of HER-2/neu expression, the epithelial cells have a high probability of transformation into anaplastic cells. However, paxillin appears to have no value as a prognostic factor. The difference of expression of HER-2/neu between IDC with DCIS and DCIS suggests a different origin of tumor cells. The growth pattern of mucinous carcinoma cell is different from the that of DCIS or IDC cell, which grow slowly.
