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.

The acromioclavicular and coracoclavicular ligament are usually injured by traffic accident or during sports. So, various methods of treatment has been introduced. Fourty four cases of acromioclaviclar and coracoclavicular ligament injuries were admitted and treated at Koryo General Hospital from March 1985 to February 1989. 26 cases were treated by operative method, 18 cases by conservative method in Grade 1, 2 and 3 injuries. The following results were obtained. 1. These injuries were more prevalent in male and more in left side. 2. The most common cause of injuries was traffic accident. 3. Among 44 cases, 13 cases were Grade 1, 9 cases Grade 2 and 22 cases Grade 3 by Allman's classification. 4. 18 cases were treated conservatively and 26 cases operatively. Conservatively treated 18 cases include 15 cases by Kenny-Howard sling and 3 cases by skillful neglect. And operatively treated 25 cases include 12 cases by modified Phemister method(46.2%), 2 cases by modified Bosworth method(7.7%), 2 cases by acromioclavicular plate method(7.7%), 2 cases by Stewart method(7.7%) and one case by Mumford method(3.8%). 5. There were good functional results with the K-wire fixation method after the acurate diagnosis by operative method in the Grade 2 injury. And in the Grade 3 injury we could get the functional results with the modified Phemister method.

Cutaneous hypersensitivity reaction due to Rhus can develop against antigens delivered through the epidermis(allergic contact dermatitis: ACD) or through the blood vessels(systemic contact dermatitis: SCD). Although the role of Langerhans cells(LC) in sensitization and elicitation of ACD(external antigen) has been extensively investigated, there are few studies in cases of SCD(internal antigen). Immunohistochemical differences of Langerhans cells were investigated in cases of two different routes(external antigen vs. internal antigen) of the same antigens. The 7 cases of ACD due to Rhus and the 14 cases of SCD due to ingestion of Rhus were involved in this study. Immunohistochemical staining with anti-CD1a, S-100 protein, HLA-DR, factor XIIIa antibodies were performed. Numbers of CD1a, S-100 protein, and HLA-DR positive cells per linear millimeter of epidermis were counted. The ratio between HLA-DR positive cells and CD1a positive cells(HLA-DR/CD1a) was considered as a possible index of activation of LC. The number of factor XIIIa positive dermal dendritic cells(DDC) per mm2 was evaluated. CD1a positive LC were more significantly numerous in ACD than in SCD(19.6+/-1.95 vs. 9.0+/-0.91 p<0.05). Also, HLA-DR/CD1a in ACD were higher than SCD. Factor XIIIa positive DDC were more numerous in SCD than in ACD(21.6+/-1.57 vs. 16.9+/-2.48), but the differences were not significant statistically. Therefore, the epidermal LC appear to be involved in antigen presentation in ACD (external antigens) as to be well-known. On the other hand, it seems possible that DDC plays some role in immune reactions in SCD (internal antigens).

The authors report series of 360 cases of transthoracic fine-needle aspiration cytology (TFNA) from Oct. 1982, through Aug. 1986 at the Seoul National University Hospital. A diagnosis of neoplastic lesion was established in 50.3% of the cases. A non-neop- lastic diagnosis was made in 38.5%, nondiagnostic one in 6.5% and inadequate one in 4.7% of the total. Statistical findings on cytological diagnoses were as follows. Specificity was 100%: sensitivity, 92%; predictive value for positive, 1.0: predictive value for negative, 0.9; concordance rate, 84.2%: diagnostic accuracy in non-neoplastic lesion, 65.4%, and typing accuracy in malignant tumor, 0.77.

PURPOSE: To determine the effect of anglulation between aorta the and renal artery on signal loss in theproximal renal artery, as seen on magnetic resonance angiography by phantom study using a pulsatile flow model. MATERIALS AND METHODS: Three phantoms of aorta and renal artery with angulation of 90 degree, 60 degree, and 30 degree wereobtained. Pulsatile recirculating flow (44%W/W glycerin, 60bpm) was used for MR angiography. First, axial 3D-TOFimages were obtained and reconstructed. MIP images were analyzed for the presence, area, and location of signalloss. 2D-PC images were obtained perpendicularly to the renal artery at a distance of 0, 4, 8 and 12mm from theostium. To calculate mean signal intensity of the renal artery, a ROI was drawn on 2D-PC images. To correlatesignal loss in 3D-TOF images with signal decrease in 2D-PC, we analyzed changes in signal intensity during onepulse cycle according to change of angulation and distance from the ostium of the renal artery by the calculatedvalues of relative signal decrease and ratio of signal decrease. RESULTS: A signal loss was observed up to 4mmfrom the ostium of the renal artery only in the case of the 90 degree phantom. Because the signal intensity measured inthe 2D-PC image of the 90 degree phantom was higher than that of the 60 degree phantom the signal loss observed in the3D-TOF images of the 90 degree phantom could not be explained by the magnitude of measured signal intensity alone.Relative signal decrease only at a distance of 0 and 4mm in the 90 degree phantom was evenly increased through a pulsecycle and the ratio of signal decrease at the same location was more than 50%. In contrast to the results of the90 degree phantom, those of 60 degree and 30 degree showed decreased of signal intensity mainly during the diastolic phase.CONCLUSION: Signal loss should become apparent at a certain angle between 60 degree and 90 degree. Decreased signalintensity causing signal loss in 3D-TOF was maintained throughout the systolic and diastolic phase of a pulsatilecycle and correlated with the ratio of signal decrease.

PURPOSE: To evaluate the accuracy of T2-weighted imaging and MR cholangiopancreatography using the single shot fast spin-echo technique for evaluating pancreaticobiliary disease. MATERIALS AND METHODS: B e t ween March and July 1997, axial and coronal T2-weighted images ( T E : 8 0 -2 00 msec) and MR cholangiopancreatograms(TE:800 -1 2 00 msec) were obtained in two ways [single slab (thickness:30 -50 mm) and multislice acquisition under chemical fat saturation] using SSFSE pulse sequencing in 131 cases of suspected pancreati-cobiliary disease. The accuracy of SSFSE MR imaging was assessed in 89 lesions of 74 patients [male,48; female,26; age range, 3 0 -86 (mean,59)years] confirmed surgicopathologically(50 lesions in 39 patients) and clinically (39 lesions in 35 patients). Two radiologists reviewed the MR images and diagnosis was determined by consensus. RESULTS: Correct diagnosis was confirmed in 84 of 89 lesions (94 %). Seven lesions were falsely interpreted, false positive and false negative results accounting for two and five cases, respective l y. Two pancreatic cancers were misdiagnosed as pancreatitis and a cancer of the proximal common bile duct(CBD) was interpreted as a distal CBD cancer. The sensitivity of SSFSE MR imaging for malignancy was 93 %. One CBD stone revealed by endoscopic retrograde cholangiopancreatography (ERCP) was not detected on MR images. In contrast, a stone in the CBD seen on MR images was not apparent on subsequent ERC P. Sensitivity and specificity for calculous disease were 96 % and 99.7 %, respective l y. A benign stricture of the ampulla of Vater was falsely interpreted as normal, and correct diagnosis was possible in two falsely diagnosed cases when MR images were rev i ewed retrospectively. CONCLUSION: The combination of T2-weighted and cholangiographic images using SSFSE is an accurate method for diagnosing pancreaticobiliary diseases.

In the thyroid tissue, thyrotrophin(TSH) and IGF-I played major role of the goitrogen. But the evidences and precise mechanism of these two factors were not known so much. Actually local secretion of thyroid IGF-I was originated from its fibroblasts mainly. We guessed major roles of IGFs in the thyroid tissue were local paracrine effect of thyroid cells proliferation and differentiation which concert with TSH. Recently, some reporters described the source of thyroid IGF-I were partly from thyroid follicular cells and its action were synergistic with TSH. We measured TSH, IGF-I and IGFBP-3 from sera and thyroid cystic fluids in 36 patients with simple thyroid cyst and examined into correlation between TSH, IGF-I and IGFBP-3.1) According to cyst/serum TSH ratio, we classified two groups(Group I; c/s TSH <1, n=19. Group II; c/s TSH >1, n=17). This classification criteria means that cystic TSH level were increased than that of serum or not.2) The serum TSH, IGF-I and IGFBP-3 levels are not difference between group I and II.3) Cystic TSH were dependent on the serum TSH in Group I, but negative correlation in Group II. In Group II, cystic TSH was significant increased.4) Serum IGF-I were positive correlation in each Group5) In Group II, cystic IGF-I was not exceed than those of serum IGF-I, but some cystic IGFBP-3 were more increased than those of serum.6) In Group II, cystic IGFBP-3 increased than serum TSH, and cystic IGFBP-3 was positive correlation with cystic TSH and cystic IGF-I.As these data suggested that cystic TSH and cystic IGF-I levels may influence cystic IGFBP-3 level. The main effect for maintenance of cyst was mediated by cystic TSH and cystic IGFBP-3. But the cystic IGFBP-3 has major role for thyroid cyst than cyst TSH.

The development of renal glomerular lesions secondary to severe visceral infection (pulmonary, pleural, retroperitoneal or hepatic abscess) is not generally appreciated. Such patients resemble those with infective endocarditis. The suggested pathogenetic mechanisms by which infection can cause glomerular damage are immunologic interaction, direct toxicity of a bacterial products, and some other triggering factors; However, direct correlation between the infectious and immunologic events has not been demonstrated. The histopathologic findings of infectious glomerulonephritis are variable, and these findings, as well as the clinical abnormalities, may resolve with effective antimicrobial therapy or abscess drainage. We experienced a case of glomerulonephritis and acute renal failure due to staphylococcal retroperitoneal abscess. The patient was a 58-year-old man who presented with abdominal and back pain. We performed an abdominal CT scan which showed a retroperitoneal abscess which was proven to be a staphylococcal infection upon percutaneous abscess drainage. Furthermore, we performed a renal biopsy in order to investigate hematuria, RBC casts, and proteinuria. Pathologic findings revealed postinfectious glomerulonephritis. Abscess drainage and sensitive antibiotics were administered, after which his symptoms and urinary abnormalities disappeared, and the retroperitoneal abscess subsided. Here, we report a case of a staphylococcal retroperitoneal abscess which led to postinfectious glomerulonephritis and acute renal failure along with a brief review of the literatures.

OBJECTIVES: This study is to investigate clinicopathologic characteristics, survival and prognostic factors in patients with Krukenberg tumor of the ovary. MATERIAL & METHODS: From Jan. 1991 to Dec. 2000, 42 patients with Krukenberg tumor of the ovary were investigated with clinical profiles, such as age, stage, primary sites, clinical symptoms, and survival, retrospectively. RESULTS: A mean age of 42 patients was 44.8 years (range 27-77). Stomach was the most frequent primary site (30/42, 71.4%), followed by colon (7/42, 16.7%) and gallbladder (1/42, 2.4%). In 38 patients, primary sites diagnosed before or after 1 month of diagnosis of Krukenberg tumor of ovary (36/38 cases, 94.7%). The most common feature of patients with Krukenberg tumor of ovary was bilateral abdominal mass. 5-year survival rate of patients with Krukenberg tumor of ovary was 8.94% (95% CI=3.33-14.55) and median survival time was 11 months. Age, bilaterality of tumor, time of diagnosis, presence of ascites and the primary site did not affect the survival. The patients who received post-operative adjuvant chemotherapy had better 3-year survival than those who did not (17.28% vs 10% p=0.03). CONCLUSION: Krukenberg tumor of the ovary is an aggressive tumor with poor prognosis. Post-operative adjuvant chemotherapy may increase the survival of patients with Krukenberg tumor of the ovary. Further prospective studies for the role of surgery and chemotherapy are needed.
