Our present knowledge of impetigo contagiosa extends from its first description as a separate clinical entity by Fox in I864, and the proof of its bacterial etiology by Radcliffe-Crocker in 1881. Both staphylococci and streptococci have been discovered from the lesions, but the relative preponderance of each varies greatly, and reports are contradictory. Seventy-eight patients with impetigo contagiosa were studied bacteriologically in order to ascertain the primary etiologic agent. Also, a susceptibility test (Bauer- Kirby method) was done on the isolated organisms with 7 antibiotics which are used frequently in the clinical field. Specimens obtained from the skin lesions were cultured and organisms were isolated. They were identified by various biochemical and serological tests. A DN ase test, a carbohydrate fermentation test, and a coagulase test were done for the isolated staphylococci. A bacitracin disc method and a precipitin test(Lancefield method) were done for the isolated B-hemolytic streptococci. The results were as follows: Fifty-six cases(71.8%) were infected by staphylococcus only. Twenty cases(25.6%) were infected by a mixture of staphylococcus and p-hemo- lytic streptococcus. Only 2 cases(2.6%) were infected by B-hemolytic streptococcus alone. All 76 strains of staphylococci were identified as coagulase positive staphylococci. Among the 22 strains of B-hemolytic streptococci, 15 strains were identified as group A and remaining 7 strains were identified as group B. Coagulnse negative sta,phylococcus was not found. In the susceptibility test to 7 antibiotics, staphylococci showed susceptibility to lincomycin, erythromycin, cloxacillin, and chloramphenicol, and resistance to tetra-cycline, penicillin, and ampicillin. Streptococci showed susc.ptibility to all of the above antibiotics except tetracycline. From the results of this experiment, it was concluded that the primary etiologic agent of impetigo contagiosa was coagulase positive staphylococcus and streptococcus for the most part can be considered as a secondarily infecting agent. Coagulase negative staphylococcus apparently is not implicated as an etiologic agent of impetigo contagiosa. The results of the antibiotic susceptibility tests would seem to indicate that the use of such antibiotics as tetracycline, penicillin, and ampicillin is not indicated in the treatment of impetigo contagiosa.

Pseudoaneurysm or false aneurysm is one of the late complication of a missed or untreated arterial injury. Most traumatic aneurysms in the extremities are false, and they are usually caused by penetrating trauma. The diagnosis of pseudoaneurysm is suggested by the presence of one or more of the followings: an expanding ill defined mass with or without pulsation, a bruit, pain, paresthesia or paralysis due to nerve compression, an absent peripheral pulse, or signs of ischemia. Although plain radiographs may demonstrate a nonspecific soft tissue mass, arteriography is essential in defining the false aneurysm or aneurysms and differentiating them from other soft-tissue masses. We are reporting the case of a patient who had a false aneurysm of the posterior tibial artery after open fracture of tibial shaft.

The authors analyzed data from 15 patients with idiopathic dilated cardiomyopathy to evaluate the hemodynamic changes and left ventricular cineangiogram as compared with normal control. Mean right atrial pressure, right ventricular systolic pressure, mean pulmonary artery pressure and mean pulmonary wedge pressure were signigicantly elevated in patients with dilated cardiomyopathy. Left ventricular enddiastolic volume was increased in idiopathic dilated cardiomyopathy(139.9+/-58.73 ml/m2). Cardiac index, left ventricular ejection fraction and circumferential fiber shortening were significantly reduced in patients with dilated cardiomyopathy as compared with normal control(p<0.001). Hypokinetic, diffuse wall motion abnormalities of left ventricle were common in idiopathic dilated cardiomyopathy. A few cases of akinetic or dyskinetic segmental wall motion abnormalities were present. Left ventricular configurations in patients with idiopathic dilated cardiomyopathy were globe shape(53.4%) as compared with pear core shape(90%) of normal control. Associated mitral regurgitations in patients with idiopathic dilated cardiomyopathy confirmed by left ventricular cineangiogram were 53.3 percent. Mild to moderate mitral regurgitations were often present(46.6%).

Breast reconstruction following mastectomy has, become increasingly popular in recent years. Reconstruction surgeons have responded to patients' needs for effective and versatile procedures that will restore the normal shape and symmetry of breasts. Among the various techniques for these purpose, transverse rectus abdominis myocutaneous(TRAM) flap is now cosidered as the most acceptable technique. However, there are some limitations to use the TRAM flap, such as heavy smoker, obesity, and previous abdominal surgery. Also TRAM flaps are not good candidates for the patients with absent anterior axillary fold. In these respects, latissimus dorsi flap can be used as an alternative method for successful breast reconstuction. Latissiomus dorsi flaps have several advantages as compared to TRAM flaps, such as reliable blood supply, versatility of skin paddle orientation, and low donor site morbidity. It is also available for patients without anterior axillary fold, such as radical mastectomy defect or Poland syndrome. Latissimus dorsi flaps, however, and implants to obtain projection and symmetry of the reconstructed breast. Main disadvantages of latissimus dorsi flap method are difference in color and texture between skins of flap and chest, and capsular contracture resulted in high riding implant or distortion of breast contour. In this study, we performed latissimus dorsi flap for reconstruction fo breast and anterior axillary fold in 10 cases. To minimize the above problems more fullness and natural shape, implants were completely covered with muscle and overexpanded for more than 3-months and then deflated to the desired volume. These maneuvers produced aesthetically acceptable results during the latissimus dorsi breast reconstruction.

BACKGROUND: Infection of hepatitis B virus(HBV) is one of the most important cause of the liver diseases in Korea, although HBV infection tends to be decreased. Diagnostic kits more accurately detecting HBV infection have been required'in order to diagnose and prevent the HBV infection. Recently LG Chemical Ltd. developed new diagnostic kits for HBsAg, anti-HBs and anti-HBc, using HBV from Korean patients. We evaluated these new kits by comparing them with microplate enzyme immunoassay (EIA) from BehringTU(Germany) and microparticle EIA (MEIA) from AbbottTM(USA). METHOD: Sera from 1,500 healthy blood donors and 500 patients were obtained to test HBsAg, anti- HBs and anti-HBc using diagnostic kits from AbbottTM, BehringTM and LG Chemical Ltd. We analyzed the results of 3 manufacturers and confirmed the discordant results of HBsAg by Southern hybridization after HBV PCR and those of anti-HBs by neutralization assay with HBsAg from LGTM. We also evaluated the reproducibility and detection limit. RESULTS: Of 1,500 healthy blood donors, HBsAg was positive in 34 (2.3%), representing completely the same results from 3 manufacturers. However, of 500 patients, 7 (1.4%) had discordant results; HBsAg was positive in all 7 sera tested with BehringTM and positive in only one tested with AbbottTM and LGTM, respectively. HBV DNA was not detected in all 7 discordant results of HBsAg, so false positive results totaled 7 (1.4%) with BehringTM and 1 (0.2%) with AbbottTM and LGTM, respectively. Of 2,000 sera, the results of anti-HBs and anti-HBc from 3 manufacturers were same in 1,876 (93.8%) and in 1,949 (97.5%), respectively. Results of HBsAg, anti-HBs and anti-HBc from 3 manufacturers were constant on repeating tests. When testing the detection limit, BehringTM kits for HBsAg and anti-HBs retained significantly higher sensitivity than AbbottTM and LGTM. On the other hand, BehringTM kit for anti-HBc showed significantly lower sensitivity than AbbottTM and LGTM. CONCLUSION: The diagnostic kits for HBV developed by LG Chemical Ltd. showed comparable results with those by AbbottTM or BehringTM and will be useful as screening blood donors or detecting patients with HBV infection.
