Aneurysm, Infected

Multiple involvement of arterial fibromuscular dysplasia is unusal and such a case is quite limited in the literature. We present a case of multiple arterial fibromuscular dysplasia with aneurysm formation in a 38-year-old non-hypertensive man. Angiographic study showed multiple aneurysmal dilatations of the right renal, superior mesenteric, celiac axis, and left colic arteries. The resected right kidney demonstrated an aneurysm of the main renal artery and extensive infarction in the midportion of the renal parenchyma. The segmentally resected superior mesenteric artery disclosed a similar nature of aneurysm occluded by recent thrombi. Microscopically, all the resected arterial walls showed both intimal and medial fibroplasia together with periadventitial fibrosis resulting in marked narrowing of the lumen and subsequent thrombus formation.

BACKGROUND: This study aimed to investigate bradycardia as an adverse effect after administration of dexmedetomidine during 33degrees C target temperature management. METHODS: A retrospective study was conducted on patients who underwent 33degrees C target temperature management in the emergency department during a 49-month study period. We collected data including age, sex, weight, diagnosis, bradycardia occurrence, target temperature management duration, sedative drug, and several clinical and laboratory results. We conducted logistic regression for an analysis of factors associated with bradycardia. RESULTS: A total of 68 patients were selected. Among them, 39 (57.4%) showed bradycardia, and 56 (82.4%) were treated with dexmedetomidine. The odds ratio for bradycardia in the carbon monoxide poisoning group compared to the cardiac arrest group and in patients with higher body weight were 7.448 (95% confidence interval [CI] 1.834-30.244, p = 0.005) and 1.058 (95% CI 1.002-1.123, p = 0.044), respectively. In the bradycardia with dexmedetomidine group, the infusion rate of dexmedetomidine was 0.41 +/- 0.15 microg/kg/h. Decisions of charged doctor's were 1) slowing infusion rate and 2) stopping infusion or administering atropine for bradycardia. No cases required cardiac pacing or worsened to asystole. CONCLUSIONS: Despite the frequent occurrence of bradycardia after administration of dexmedetomidine during 33degrees C target temperature management, bradycardia was completely recovered after reducing infusion rate or stopping infusion. However, reducing the infusion rate of dexmedetomidine lower than the standard maintenance dose could be necessary to prevent bradycardia from developing in patients with higher body weight or carbon monoxide poisoning during 33degrees C targeted temperature management.

OBJECTIVES: REM sleep behavior disorder (RBD) has received little attention in epidemiologic studies. This study aimed to determine the prevalence of probable REM sleep behavior disorder (pRBD) in the elderly population and its clinical features. METHODS: A random sample of 1,588 was selected from a roster of 14,050 elderly population living in Osan city. The subjects were asked to fill out the REM sleep behavior disorder screening questionnaire (RBDSQ). Subjects whose score were 5 or higher on RBDSQ underwent a diagnostic phase of person-to-person assessment by experts in RBD. RESULTS: Among 1,588 subjects, 886 elderly subjects participated in the screening phase and 123 subjects were assessed in the diagnostic phase. Eleven subjects were diagnosed as having pRBD, so prevalence was 1.5% (95% CI=0.70-2.30%). The frequency of depression and cognitive decline was significantly increased in patients with pRBD compared to subjects without pRBD, and there was no difference in sleep disturbances between two groups. CONCLUSIONS: Probable REM sleep behavior disorder is not rare in the elderly but frequently under-recognized. More attention should be paid to evaluation and treatment of RBD.

BACKGROUNDs: A retrospective study was performed to define objective radiologic parameters in diagnosing epiglottitis on soft-tissue lateral neck radiographic study. METHODS: Parameters of soft-tissue structures(epiglottis width, third vertebral body width, ratio of epiglottic width to third vertebral body width) in 30 adult patients compared with those of age and sex-matched controls with foreign body in throat whose radiographic reading was normal. RESULTS: Epiglottis width of more than 11mm, ratio of epiglottis width(EW) to the third vertebral body width(C3W) of more than 0.5 were, respectively, found to be 100% sensitive and specific in differentiating between patients with and without epiglottitis. CONCLUSION: These preliminary results suggest that EW/C3W ratio of more than 0.5, EW of more than 11mm, respectively, may be useful in the diagnosis of epiglottitis in adult patients.

BACKGROUND: Steroid myopathy is an unexpected side effect to the prolonged therapeutic use of steroids. To treat steroid myopathy, the followings are recommended; reduction of the steroid dose, usage of a nonfluorinated steroid, and conversion to an alternate day regimen. As muscle loading is encouraged in maintaining normal muscle properties, it is also apparent that physical exercise may be useful in the prevention and treatment of steroid myopathy. METHOD: The experiment was designed to investigate the effects of exercise on steroid myopathy. Rats being treated with triamcinolone acetonide (TA) (5 mg/kg/day) for 7 days exercised on a treadmill (speed 20m/min, 30 min/day, 3 days/week) for 2 weeks. The extensor digitorum longus (EDL) and soleus were then examined histochemically and ultrastructurally. RESULTS: Rats treated with TA showed significant loss of body and muscle weight. In the TA treated group, cross-sectional areas of type II fibers of both EDL and soleus were decreased in comparison with the controls. Necrotic changes were found only in type II fibers of the soleus. Recovery from the weight loss with type II fiber atrophy was more pronounced in the exercise group than that of the sedentary group, but was not significant statistically. Ultrastructural abnormalities, that consisted of subsarcolemmal mitochondrial accumulation, mitochondrial vacuolation, increased number of mitochondria in autophagic vacuoles, and dilatation of sarcoplasmic reticulum, were seen in TA treated muscles. These injuries were significantly reduced by the exercise, however, complete recovery could not be seen. CONCLUSIONS: These results suggest that treadmill exercise for 2 weeks partially ameliorate steroid myopathy in.

Hepatitis C virus (HCV) E2 protein is known to be one of putative envelope proteins. To develop a sensitive detection method for HCV infected tissues and cells, monoclonal antibodys (MAbs) to the E2 protein of HCV were prepared from mice immunized with recombinant baculovirus-expressing E2 protein (Bac-E2). Several hybridoma clones secreting various levels of MAb were isolated and isotypes of these MAb were determined. One clone (L.2.3.3) was used for ascites production and the E2-MAb was purified and characterized. The L.2.3.3 reacted well with both Bac-E2 and E. coli expressed glutathione-5-transferase-E2 (GST-E2) fusion proteins. Using HCV patient sera, E2 envelope protein was found to be localized in the cell membrane boundary both in CHO cells and insect cells which express HCV E2 protein. Similar result was obtained when same cells were treated with the MAb L.2.3.3. These results demonstrated that Bac-E2 protein is capable of eliciting high titer antibody production in mice.
