To assess the effectiveness of Magnetic Resonance Imaging (MRI) with endorectal surface coil in the ataging of carcinoma of the uterine cervix with emphasis on parametrial involvement. Thirty women with clinically and radiographically proven carcinoma of the uterine cervix were initially included for this study, but thirteen patients were excluded since the stages of tumors wore beyond stage IIa. CT and MR findings of the remaining seventeen patients were performed at Cheil General Hospital and compared a1ong with clinical findings with the special emphasis on the parametrial involvement by the tumor. Staging was assessed by CT and MRI, and the results were compared with the pathologic staging. Radiea1 abdominal hysterectomy with the pelvic and paraaortic lymphnode dissection was done to all sewenteen patients. The staging made primarily by CT and MRI was either stsge 1 or Ila, but MR images with endorectal surface coil was superior to CT in the visualization of depth of tumor infiltration, especially parametrial involvement. The determination of the depth of the tumor made by MR images showed statistically significant correlation with histologic evaluation(R =0.768, p<0.01). The accuracy rate for the evaluation of the parametrial invo1vement was 82.3% far CT and 94.1% for MRI with endorectal surface coil. The overall accuracy rate for tumor staging was 70.5% for clinical, 58.8% for CT and 82.3% for MR evaluation. The accurecy rate in evaluation of the pelvic and paraaortic lymphnode was 88.2% for CT, but the evaluation done by MRl was not adequate due to small FOV(field of view). In assessment of The steging of careinoma of the uterine cervlx, MR images with endorectal surface coil was superior to CT, especially in the evaluation of the parametrial involvement.

Basal cell carcinoma(BCC) and squamous cell carcinoma (SCC) are very prevalent neoplasms of the human skin. Ultraviolet radiation in sunlight is a well-established mutagen of the p53 gene and is one of basal cell carcinoma and squamous cell carcinoma. The newly-formed vascular network is important for neoplasms to grow beyond a size of about 1 mm2. Recent reports have suggested the hypothesis that a mutant p53 protein is closely related with capillary density. Immumohistochemistry for p53 protein and CD34 was performed in 20 cases of BCCs and 14 SCCs to evaluated the relationship between p53 protein and capillary density. The results were as follows:1. The microvessels stained by CD34 were mainly located in the interface of tumor cells and stroma. 2. There was no difference in the microvessel density according to the histologic types and age of the patients, but a higher microvessel density was noted in male patients. 3. The aggressive BCCs and the less-differentiated SCCs showed higher p53 immunostaining. 4. The mean microvessel density of cases showing strong positive immunostaining of the p53 gene(54.73+/-17.75) was higher than that of others(39.75+/-18.30). These results suggested that p53 protein expression and microvessel density are not related to the histologic types and age of the patients, but that differentiation and biologic behavior such as the infiltrating property of tumors and the microvessel density are closely related to p53 protein expression.

BACKGROUND: The effective ventricular function during ejection and filling is likely to depend on the coordinated action of the longitudinally and circumferentially orientated myocardial fibers and the function of these longitudinal fibers has not been extensively studied. METHODS: The role of longitudinally and circumferentially orientated fibers in left ventricular wall motion was evaluated by M-mode echocardiograms of the mitral ring(whose motion reflect long axis change) and the standard minor axis(left ventricular posterior wall), simultaneous recordings of phonocardiograms and electrocardiograms on the paper (speed 100mm/sec), in 24 healty individuals, 17 patients with mitral stenosis, 11 patients with open mitral commissurotomy and 17 mitral valve replaced patients. RESULTS: In the controls long axis shortening significantly preceded minor axis shortening (phase difference between two axes : 20+/-3 msec, mean+/-SEM) during early systole, indicating left ventricle become more spherical. This phase difference was also observed in the patients with mitral stenosis and in those with open mitral commissurotomy. In patients with mitral valve replacement(MVR) whose papillary muscles had been sectioned, the onset of long axis shortening was more delayed during early systole than that of short axis(-33+/-6msec) and the end of shortening was also prolonged to early diastole more than that of normal controls (54+/-3 msec vs 90+/-8 msec, mean+/-SEM, p<0.01 by t-test). CONCLUSION: We observed the time relations between long and short axis motion in normal controls. It can be concluded that the reversed time relation in patients with MVR is one of the important factors which may effect negatively on ventricular function and long-term prognosis, thus the surgical procedures to preserve papillary annular continuity should be considered in patients with mitral valvular disease. And the controlled, prospective, clinical trials with homogenous groups of patients are needed to evaluate the potential benefits of papillary annular continuity in preserving atrio-ventricular interaction in patients undergoing mitral valvular surgery.

Tumour-induced hypoglycemia is usually caused by insulinoma or non-islet-cell neoplasm, such as hemangiopericytoma, fibrosarcoma, mesotheliomas. Most of the neoplasms in non-islet-cell tumour-induced hypoglycemia are mesenchymal type, and have a common features, including large-sized, slow-growing and metastatic involvement of the liver. The mechanisms of hypoglycemia in metastatic liver disease are not clearly defined, and liver failure secondary to hepatic metastasis or insulin or insulin-like mediated process are considered. Glucagon stimulation test has been used to distinguish between insulin-mediated or insulin-like-mediated hypoglycemia and hypoglycemia induced by liver failure. We experinced a case of hypoglycemia in a patient of hemangiopericytoma with liver metastasis in which glucagon stimulation test was used for proper evaluation. We compare this case with previously reported cases, and present here with brief review of literatures.

PURPOSE: The purpose of this study was to examine the possible direction of critical care nursing research in the future by analyzing the trends of recent Korean studies.METHOD: Using a database search, we selected 263 articles on critical care nursing that were published in Korean journals between 2008 and 2017. Then, we conducted an integrative review of the contents of the selected articles and analyzed the English abstracts using the relevant packages and functions of the R program.RESULTS: The number of studies concerning critical care nursing has increased over the 10-year period, and the specific topic of each study has diversified according to the time at which it was conducted. In terms of quality, the majority of the research was published in high-level academic journals. The key words regularly studied over the past decade were: knowledge, delirium, education, restraint, stress, and infection. Studies related to vancomycin-resistant enterococci infection, compliance, and standards have decreased, while studies related to death, communication, and safety have increased.CONCLUSION: Randomized controlled trials and protocol research for evidence-based critical care need to be conducted, as does research on family involvement. The key word analysis of unstructured text used in this study is a relatively new method; it is suggested that this method be applied to various critical care nursing research and develop it methodologically.

Klebsiella pneumoniae causes pyogenic infections in various sites, with the risk of which increases in patients with diabetes mellitus. Recently, K. pneumoniae has emerged as a leading cause of pyogenic liver abscess. Primary liver abscess caused by K. pneumoniae in the absence of underlying hepatobiliary disease is commonly associated with metastatic infections such as endophthalmitis, meningitis, brain abscess and infection in other sites. We experienced a case of K. pneumoniae liver abscess associated with septic metastatic lesions including pyomyositis and infected aneurysm of aorta. Despite the aggressive management with antibiotics, surgical pus drainage and aortic bypass graft, patient died of ventilator associated pneumonia and multiorgan failure. Our experience suggests that clinicians should be alert to septic metastatic infections when they treat a patient with K. pneumoniae liver abscess.

Annals of Rehabilitation Medicine 2023;47(3):192-204
Objective:
To determine correlations of alternation motor rate (AMR), sequential motor rate (SMR), and maximum phonation time (MPT) with the severity of dysphagia in subacute stroke patients.
Methods:
This was a retrospective chart review study. Data of 171 subacute stroke patients were analyzed. Patient’s AMR, SMR, and MPT data were collected from their language evaluations. Video fluoroscopic swallowing study (VFSS) was done. Data of dysphagia scales including penetration-aspiration scale (PAS), American Speech-Language-Hearing Association National Outcomes Measurement System (ASHA-NOMS) scale, clinical dysphagia scale (CDS), and videofluoroscopic dysphagia scale (VDS) were obtained. AMR, SMR, and MPT were compared between a non-aspirator group and an aspirator group. Correlations of AMR, SMR, and MPT with dysphagia scales were analyzed.
Results:
AMR ("ka"), SMR, and modified Rankin Scale were significant associated factors between non-aspirator group and aspirator group, while AMR ("pa"), AMR ("ta"), and MPT were not. AMR, SMR, and MPT showed significant correlations with PAS score, ASHA-NOMS scale, CDS, VDS oral, and VDS pharyngeal scores. The cut-off value for distinguishing non-aspirator group and aspiration group was 18.5 for AMR ("ka") (sensitivity of 74.4%, specificity of 70.8%) and 7.5 for SMR (sensitivity of 89.9%, specificity of 61.0%). AMR and SMR were significantly lower in before-swallow aspiration group.
Conclusion
Articulatory diadochokinetic tasks that can be easily performed at the bedside would be particularly helpful in determining the oral feeding possibility of subacute stroke patients who cannot undergo VFSS, which is the gold standard for dysphagia assessment.

Moyamoya disease (MMD) is a cerebrovascular disorder characterized by bilateral stenosis or occlusion of the terminal portions of the internal carotid arteries. MMD is also accompanied by typical net-like collateral vessels in the basal ganglia. Although the etiology of MMD remains unknown, hereditary, immunogenic, and hemodynamic factors have been implicated as underlying mechanisms of MMD. Here, the authors report on one patient with a rare combination of Graves' disease-associated thyrotoxicosis, myasthenia gravis, and MMD, where cerebrovascular ischemic events occurred during a thyrotoxic state.

OBJECTIVE: Immunotoxin therapy is a novel approach for the treatment of tumor, and it has been successfully used in the central nervous system. The purpose of this study is to evaluate the cytotoxicity of OKT9 ScFv-Diphtheria toxin fusion immunotoxin on various human brain tumor cell lines. METHODS: Immunotoxin which was composed of OKT9 ScFv and Diphtheria toxin was made. Its cytotoxicity on glioblastoma cell lines(U87MG, U118MG) and medulloblastoma cell line(TE671) was tested and compared with anti-cancer chemotherapeutic agents. And we also examined the relationship between its cytotoxicity and transferrin receptor expression. RESULTS: It showed most cytotoxicity on U87MG cell line and nearly no effect on U118MG cell line, moderate cytotoxicity on TE671 cell line in sixteen hours exposure experiment. In continuous exposure experiment, it showed moderate cytotoxicity on U118MG cell line, but showed strong cytotoxicity on other cell lines comparable or higher than anti-cancer chemotherapeutic agents. The relationship between its cytotoxicity and transferrin receptor expression was tested using flow cytometry, but no direct relationship could be found. CONCLUSION: Collectively, the result shows the cytotoxic effects of OKT9 ScFv-Diphtheria toxin fusion immunotoxin against various human brain tumor cell lines in continuous exposure experiment. Therefore, we suggest that this immunotoxin could be developed as a potential immunotherapeutic agent in the treatment of various human brain tumor clinically.
