We reviewed the cases of 9 patients with vascular lesions in thalamus, 5 hemorrhage and 4 infarctions that were confirmed clinical and CT findings. Generally CT scan and clinical datas proved to be helpful to the diagnosis and prognosis to thalamic lesion. However, these findings are not exactly correlated to prognosis of patients. We can gain more informative factors to our patients for Multimodal evoked potential examination (MEP) to analysis. Especially in our cases, MEP findings proved to be the most effective results in the determinations of the prognosis. We review the literature and discuss the treatment and discuss the treatment and prognosis in thalamic lesion. Emphasis is placed on the current and optimal method of the evaluation of prognosis in thalamic lesions using MEP combined with the finding of CT scan and clinical status.

An assessment of early graft function in canine single lung transplant recipients was made by analysing early postoperative radiographic progression, lung perfusion, bronchial patency and bronchial anastomotic wound healing and histopathology of the allografted lung. Eighteen mongrel dogs weighing 15kg on average were used. Donor lung bloc with a generous atrial cuff, the pulmonary artery and left bronchus were taken and flushed with Euro-Collins solution which implanted in the pneumonectomized recipient dog. Anastomosis was done with the atrium, pulmonary artery and bronchus in that order. To assess an early graft function, a protocol for a grading system was designed into the chest roentgenogram, lung perfusion scan, bronchial patency and histopathologic progression of the bronchial anastomosis and allografted lung (Table 1). The results were obtained as follows: Radiographically, clear to infiltrate was seen in 67% (8/12), 33% (5/15), 30% (3/10) and 33% (2/6) on postoperative day 0, 1, 2 and 3 respectively. Lobar to total opacification was 33% (4/12), 67% (10/15), 70% (7/10) and 67% (4/6) on days 0 to 3 (Table 2). Perfusion scan showed normal to mild defect in 43% (3/7) and moderate to severe defect in 57% (4/7) on day 0 and 100% (5/5) on day 2 (Table 3). The bronchial anastomotic site showed patent to mild stenosis in 100% (8/8) on day 0 and mild stenosis in 2/2 on day 9 bronchofiberscopically, and showed normal wound healing in 38% (3/8), cellular infiltration in 38% (3/8) and infarction in 25% (2/8) up to day 9 postoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)

Pulmonary lobar transplantation provides a clue to the acute donor shortage. To examine the experimental and clinical applicability of lobar transplantation, the authors observed the extent of lung expansion and infiltrate in the allografted lobe through the sequential analysis of the early chest roentgenograms. MATERIALS AND METHODS: Twenty two mongrel dogs weighting 17 kg on average were used. Donor lung bloc was taken and flushed with Euro-Collins solution. The left lower lobar bloc was procured and implanted in the pneumonectomized recipient dog. The anastomosis was performed in the order of the pulmonary vein, artery, and bronchus. To assess the radiological pattern in the lobar allograft, a grading system was designed according to the extent of lung expansion and infiltrate. RESULTS: A) Expansion pattern: Good to excellent lung expansion was seen on postoperative day 0 in 6 out of 10 dogs; on day 1, 4/7; day 2, 3/12; day 3, 1/1; and day 4, 1/3, respectively. Radiographs on day 6, 7, and 12 also showed good expansion in one dog. B) Lung opacity pattern: Clear to minimal infiltrates were seen on day 0 in 8 out of 10 dogs; day 1, 7/17; day 2, 2/12; and day 4, 1/3. The same appearances were detected in a single dog on day 6, 7, and 12. C) Expansion-opacity correlation pattern: Radiographs on postoperative day 0 showed good expansion with mild infiltrates, and excellent expansion with minimal infiltrates were observed on day 1 in 3 out of 17 dogs, day 2, 1/12; and day 4, 1/3, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

BACKGROUND: Since the introduction of warm blood cardioplegic myocardial protection, the results of numerous clinical trials have been reported. However , the increased reliance oncrystalloid cardioplegia with longer cross clamp time, the controversies surrounding the issue of right ventricular protection with retrograde cardioplegia, and problems of securing a good operative field of vision have all been pointed out as unresolved. To overcome these shortcomings, Antonio et al, in 1995 published the use of intermittent warm blood cardioplegia by admixing potassium only with good clinical results. The obj ectives of the current investigation were to assess the effects and applicability of warm blood cardioplegia with potassium only. MATERIAL AND METHOD: From May of 1998 to January of 1999, the results of coronary surgery or open heart surgery in 70 patients under intermittent warm blood potassium only cardioplegia were compared with the results of 70 case matched patients undergoing similar operations with intermittent cold blood cardioplegia. RESULT: The amount of cardioplegic solution required during cardiopulmonary bypass(1463+/-68.0 min, 3584+/-179 min, p<0.001), the time to recovery of consciousness postoperatively(3.5+/-0.4 min, 4.9+/-0.8 min, p=0.044), intubation duration(10.8+/-0.8 hr , 13.2+/-0.6 hr , p=0.017), and the inci-dence of rrhythmia requiring the use of lidocaine(75.2+/-6.8 mg, 114.5+/-7.2 mg, p=0.006), which were found to be less in the warm potassium only group were statistically significant. However, the differences in postoperative cardiac enzymne elevation and postoperative mortality and morbidity were statistically insignificant. CONCLUSION: The current study showed warm intermittent potassium only blood cardioplegia to be at least equally effective as cold intermittent blood cardioplegia in providing myocardial protection. Furthermore, the reduction in cardiopulmonary bypass, mental recovery and intubation times strongly support the use of this method for intraopertaive myocardial protection.

Many advances, including the development of antibiotics, the advent of diagnostic techniques and the use of nonsurgical drainage have decreased the mortality rate of pyogenic liver abscess. But, early prompt diagnosis and proper treatment is mandatory in gas-forming pyogenic liver abscess because it may run a fulminating course to death. Gas-forming pyogenic liver abscess mostly occurred to old diabetics. Symptoms of duration are shorter and the prognosis is poorer in the gas-forming than in the non-gas-forming liver abscess. We report three cases of gas-forming pyogenic liver abscess which occurred in old diabetic patients. They were successfully managed by parenteral antibiotics and early percutaneous drainage under sonographic guidance. Early and adequate drainage of pus by pigtail catheter may play a crucial role on the treatment of gas-forming liver abscess.

Toxic effects of ozone, 4-(N-methyl-N-nitrosamino)-1-(3- pyridyl)-1-butanone (NNK), and/or dibutyl phthalate (DBP) were examined through NF-kappaB, AP-1, Nrf2, and osteopontin (OPN) in lungs and livers of B6C3F1 mice. Electrophoretic mobility shift assay (EMSA) indicated that mice treated with combination of toxicants induced high NF-kappaB activities. Expression levels of p105, p65, and p50 proteins increased in all treated mice, whereas IkB activity was inhibited in NNK-, DBP-, and combination-treated ones. All treated mice except ozone-treated one showed high AP-1 binding activities. Expression levels of c-fos, c-jun, junB, jun D, Nrf2, and OPN proteins increased in all treated mice. Additive interactions were frequently noted from two-toxicant combination mice compared to ozone-treated one. These results indicate treatment of mixture of toxicants increased toxicity through NF-kappaB, AP-1, Nrf2, and OPN. Our data could be applied to the elucidation of mechanism as well as the risk assessment of mixture-induced toxicity.

Ochrobactrum anthropi is an oxidase-producing, non-lactose-fermenting, gram-negative bacillus that is frequently isolated from the environment including sinks, baths, soil, and hospital water sources. Recently O. anthropi have been reported as an emerging opportunistic pathogen in immunocompromised patients, particularly in those with indwelling venous catheters. Most O. anthropi were highly resistant to beta-lactam antibiotics except carbapenem. We report a case of O. anthropi bacteremia with an unusual pattern of antibiotic resistance compared to previous reports. A 47-year-old woman undergoing camptobell/cisplatin chemotherapy via indwelling venous catheter (chemoport) for stage IV ovarian cancer, had septicemia due to O. anthropi of unknown origin. The isolates were resistant to all beta-lactams and meropenem and susceptible to aminoglycoside, ciprofloxacin, and trimethoprim-sulfamethoxazole. She recovered from sepsis with combination treatment with imipenem and ciprofloxacin for 3 weeks.
