Cholangitis, Sclerosing*

A 53-year-old woman presented with dyspnea. She had undergone extended thymectomy for an invasive thymoma two months prior. CT revealed numerous small nodules in the lung. After that, she deteriorated owing to acute respiratory distress syndrome (ARDS), and the vascular surgeon planned veno-venous extracorporeal membrane oxygenation (ECMO). During percutaneous cannulation through the left femoral vein, a vascular injury was suspected, and the patient’s vital signs became unstable. Diagnostic angiography showed a ruptured left common iliac vein, and the bleeding was stopped by placement of a stent-graft. May-Thurner syndrome was diagnosed on abdominal CT. Here, we report a rare case of ECMO-related vascular injury in a patient with an unrecognized anatomical variant, May-Thurner syndrome.

The result of artificial skins made with collagen is poor after grafting over the full thickness wounds due to their rapid degradation by enzymatic cleavage. This study is an in vivo study of an artificial skin made with a biodegradable polymer, which can better address the problem of the collagenous artificial dermis. To investigate the availability of a biodegradable polymer for an artificial dermis and to get an information about the optimal degradation rate of a polymer for an artificial dermis, we made an artificial dermis by seeding of fibroblasts within the vicryl mesh and made a bilayer artificial skin by covering the artificial dermis with cultured keratinocytes. And these artificial dermis and artificial skin were evaluated in a full thickness wound model. The results are as followings: 1. The artificial dermis was available for grafting for 1 week culture of vicryl mesh-fibroblast. 2. The artificial dermis retarded the contraction of full thickness wounds. 3. The artificial dermis generated the granulation tissue and accepted the STSG completely. 4. The generated tissue from the artificial dermis had incorporated into the surrounding tissue by 4 weeks postgrafting. 5. Vicryl in the artificial dermis became to biodegrade from the culture period and absorbed completely by 5 weeks. 6. The epidermal portion was poorly differntiated during in vitro culture period. In conclusion, the polymer-fibroblast graft can retard the wound contraction and generate a new tissue permitting a useful dermal replacement. And to get more optimal results, another polymer which has slower biodegradation rate than vicryl should be used for the artificial dermis and the epidermal portion should be differentiated after in vivo grafting.

Body fluid Lactate dehydrogenase and its isoenzyme Measurement was performed in 132 patients: 8 cases with peritonitis, 21 cases with malignant ascites, 43 cases with liver cirrhosis, 48 cases with tuberculous pleuritis, 12 cases with malignant pleural effusion respectively. Body fluid protein and glucose contents, red blood cell counts, white blood cell counts, cytologic examination were also performed as a comparative study. The results were as follows: 1. Measurement of total LD and protein amount could differentiate between transudate and exudates in the ascitic fluids. 2. In the malignant exudate of ascites and pleural fluid, the activity of LD2 isoenzyme was statistically increased compared with that of inflammatory exudates and the activity of LD4 isoenzyme was also incereased compared with that of serum (P<0.05). 3. The inflammatory exudates of pleural fluid and ascites demonstrated the increase of LD5 isoenzyme activity statistically compared with that of serum and malignant exudates (P<0.05). 4. A difference of total LD activity between malignant ascites and inflammatory ascites was significant statistically, while this was not observed in the pleural exudate. 5. Total LD and LD5 isoenzyme activity didn't correlated with the number of white blood cells in the exudate.

Antimicrobial susceptibility of the bacterial strains isolated from clinical specimens during the period from June, 1983 to June, 1986 in Yeungnam Medical Center was studied and the following results were obtained. 1. Staphylococcus aureus was highly susceptible to cephalothin and its susceptibility to methicillin was gradually reduced. 2. Streptococcus strains except enterococcus were generally susceptible to penicillin, while most enterococci were susceptible to only ampicillin. 3. Gram-negative rods including Escherichia coli were highly susceptible to amikacin and tobramycin. 4. Serratia were generally less susceptible to the amtimicrobials tested than other Enterobacteriaceae. Among them, Serratia marcescens showed the highest susceptibility to amikacin and chloramphenicol. 5. Pseudomonas aeruginosa revealed the highest susceptibility to amikacin and tobramycin and moderate susceptibility to carbenicillin and gentamycin. 6. Acinetobacter calcoaceticus revealed low susceptibility to most antimicrobials tested, showing only 30% susceptibility to amikacin, tobramycin and gentamycin in 1986.
