Malignant Atrophic Papulosis*

Image-guided localized, water-suppressed in vivo 1H MR spectroscopic studies were performed on the brain tumors in 3 patients. In all 3 patients, in vivo 1H MR spectra in brain neoplastic tissues revealed that the signal intensities of N-acetylaspartate (NAA) choline (Cho) resonances were decreased and increased, respectively, comparing with healthy normal tissue. A distinct lactate signal was identified in all three patients. A ratio that the observed metabolite alterations from localized, water-suppressed in vivo 1H MR spectroscopy can be useful as an index of brain tumors, and that the technique is clinically to highlight as one promising modalities in brain tumors for more accurate diagnosis.

BACKGROUND: This study was performed to develop a dietary self-efficacy questionnaire and to determine how dietary self-efficacy is related to selected biochemical markers and health-related quality of life in hemodialysis patients. METHODS: Participants included 172 patients who had been participating in a dialysis program for at least 6 months at two teaching hospitals. A questionnaire was used to assess socio-demographic factors, dialysis-related factors, dietary self-efficacy, and kidney disease quality of life (KDQOL). Serum levels of potassium and phosphorus and interdialytic weight gain were also measured. RESULTS: The internal reliability of dietary self-efficacy was 0.944 (Cronbach's alpha). Principal component analysis resulted in two factors, situational self-efficacy of compliance with dietary guidelines and self-efficacy of food choice. The correlation analysis showed a significant association between situational self-efficacy of compliance with dietary guidelines and serum potassium and KIDQOL. The average scores of situational self-efficacy of compliance with dietary guidelines and self-efficacy of food choice in the participants were 3.52+/-0.72 and 3.61+/-0.71 respectively. Multiple linear regression analysis showed that the situational self-efficacy of compliance with dietary guidelines was significantly associated with serum potassium level and KDQOL and self-efficacy of food choice was significantly associated with KDQOL. CONCLUSIONS: Based on our results, the developed dietary self-efficacy questionnaire may be a suitable survey tool for hemodialysis patients, which can play a role in predicting clinical indicators of patient and health-related quality of life. We recommend further research into clarifying whether the positive effects of increased dietary self-efficacy is maintained in long-term dialysis patients.

The purpose of this report is to present the results of clinical observation upon 21 surgical cases with tic douloureux (female 13, male 8) during the period from January, 1960 to August, 1972 at the Department of Neurosurgery, Seoul National University Hospital, Seoul, Korea. The average age at onset was 48 years of age ranging from 22 to 66 years. The average duration from onset to operation was 5 years. The frequency of involvement was the highest in the maxillary division, next was maxillary and mandibular division, and none in the ophthalmic division. Whole division was involved in one case. Right-sided involvement predominated by a ratio of 2 to 1 and bilateral involvement was found in only one case. Extraction of innocent teeth, ungratifying operation upon paranasal sinus had been carried out in 11 cases as consequence of misdiagnosis. Alcohol injection of peripheral branches of trigeminal nerve and medical treatment produced short-lived or none-effectiveness. Trauma to ipsilateral mandible and epidermoid cyst at cerebellopontine angle seemed to be the cause of tic doulourex in 2 cases, respectively. Major complications observed in Frazier's method group, were paresthesia, facial nerve palsy, partial paralysis of motor root, and recurrence of neuralgia. All of the peripheral nerve avulsion group developed recurrence of pin within three years. Mild decrease of cornea reflex was noted in two cases of Dandy's method group. Posterior fossa operation stands in superiority, when it is considered that some pathologic lesions are frequently found in the posterior fossa, that motor root is less frequently injured, and that the light touch is so fairly preserved in all three divisions that the least damage to the cornea is expected.

Actinomycosis of the paranasal sinuses is rare and usually arises from the oral cavity after a dental procedure or trauma. Actinomycosis of the maxillary sinus is very rare and found only in isolated case reports. We report the case of a 62-year-old patient with actinomycosis accompanied by a fungal ball in the maxillary sinus.

BACKGROUND: The inhibitory effects of nitric oxide(NO) on platelet adhesion and vascular smooth muscle cell(VSMC) proliferation may have a possible role inhibiting development of neointima following balloon catheter induced injury. We tested the hypothesis that L-arginine, the precursor of NO, would attenuate neointima formation following balloon catheter induced injury via regulation of antagonistic balance between proliferation and apoptosis of VSMC. METHODS: Adult, male Sprague-Dawley rats(300 to 400g) were anesthetized with ketamine (100mg/kg intraperitoneally). The left common and external carotid artery were exposed. For endothelial denudation, 2mm angioplasty catheter was introduced through the left external carotid artery into the left common carotid artery. The catheter was inflated at I atm. and withdrawn three times. Animals were randomized to receive 2.25% L-arginine in their drinking water(n=14) or placebo(n=16) from 2 days prior to and 9 days following denudation. VSMC proliferation was quantified by immunohistochemical staining with an antibody to the proliferating cell nuclear antigen(PCNA). The cells undergoing apoptosis were identified by terminal nucleotidyl transferase-mediated nick end labeling(TUNEL) method and morphologic changes by computerized planimetry and transmission electron microscopy. RESULTS: 1) The neointimal area in injured arteries were significantly reduced in L-arginine supplemented animals compared with placebo group(p<0.05). 2) L-arginine administration significantly reduced the number of PCNA positive cells in neointima when compared with placebo at 9 days(p<0.05). 3) Positive TUNEL cells were not influenced by L-arginine supplementation. 4) On transmission electron microscopy, there were no cells showing characteristics of apoptosis in neointima. CONCLUSION: These results suggested that the inhibitory effect of L-arginine on neointima formation is due to reduced VSMC proliferation, but is not due to increased VSMC apoptosis at the early time period after initmal injur .

Local spinal cord cooling and glucocorticoid administration have been shown to diminish the degree of traumatic hemorrhagic necrosis and improve spinal cord function after impact injury. Local cooling is said to influence multiple neural enzymatic processes diminish the cellular metabolic rate and lessen the oxygen requirements. Steroid is known to maintain vascular integrity after injury and protect cellular membrane in the state of poor perfusion. As a preliminary report, this experimental study demonstrated the sequence of pathologic changes occurring from hours to days after the spinal cord of a cat had been impacted by a 400gm-cm force respectively and, thereafter evaluated the effect of local cooling and steroid administration on the functional recovery of the spinal cord. Spinal injuries was produced by dropping a 20gm weight 20cm height through a vented guide tube to strike the exposed dura and cord. Animals were sacrificed hours or days after injury. The thoracic cord was removed to include the injured tissue adjacent cord for control. The specimens were taken for histological study and this was correlated with the clinical observation by Tarlov's classification. In the acute group (From 1 hour to 8 hours after injury), multiple hemorrhage and necrosis occurred in the central gray matter and periaxonal swelling in the white adjacent to gray matter. At 15 days all most gray matter was replaced by a large central cavity in which numerous lipid phagocytes were accumulated and disruption of white matter was severe in the adjacent to the cavity. The motor neurons were shown complete central chromatolysis in the all groups.
