A 49-year-old woman with anemia who developed headache and seizure after blood transfusion was
diagnosed with posterior reversible encephalopathy syndrome (PRES). Magnetic resonance imaging
showed typical PRES findings including lesions in bilateral parieto-occipital subcortical white matter
and overlying cortex. Only a few cases of PRES after transfusion have been reported and this case is
unique in that there was a latent period between infusion and development of PRES. We postulate that
rapid change of hemoglobin level may disrupt cerebral autoregulation and result in delayed PRES. We
suggest that neurological symptoms after blood transfusion should be appropriately investigated.

Intussusception is the most common cause of acquired intestinal obstructions during infancy and early childhood. Barium reduction and pneumoreduction have been sued widely as nonsugical method of treatment in radiologic department. In the past, attempts at barium reduction of intussusception were contraindicated in the presence of frank intestinal obstruction, shock, fever, dehydration, bowel perforation, peritonitis and longstanding symptoms. At present, however, there is no agreement on the contraindications, except for shock, peritonitis and bowel perforation. Especially, there is no consensus regarding its application on patient presenting with sign of frank intestinal obstruction. The authors analyzed the effect of pneumoreduction in the intussusception with sign of frank intestinal obstruction. Pneumoreduction was attempted in 53 cases of intussusception with sign of frank intestinal obstruction. Reduction was successful in 43 cases(81%). The mean fluroscopic time was 15.1 minutes and mean maximal pressure was 121.8mmHg in successful reduction. As complications, two cases of bowel perforation were observed, but could be treated surgically without any significant problem. In conclusion, pneumoreduction is a useful substitute for barium reduction in the management of pediatric intussusception with sign of frank intestinal obstruction.

Scrub typhus (Tsutsugamushi disease)is an acute febrile systemic illness caused by Rickettsia tsutsugamushi that is transmitted to humans by the bite of larval-stage trombiculid mites (chiggers). The authors analyzed chest radiographic findings of scrub typhus in 160 patients in Ulsan area. One hundred and eight (67.5%) of160 patients showed abnormal findings which included lung lesions in 108 patients (67.5%), cardiomegaly in 37 patients (23.1%), lymphadenopathy in 25 patients (15.6%) and pleural effusion in 11 patients (6.9%). Among the lung lesions, interstitial patterns were seen in 107 patients (66.9%), mostly fine or medium reticulonodular, and air-space patterns in 14 patients(8.8%) and combined interstitial and air-space patterns in 13 patients (8.1%). Sixty-four patients(40%) had combined chest radiographic findings. The typical chest radiographic findings of scrub typhus would be helpful in evaluation of the causes of acute febrile illness that occur during late fall in the endemic area.

PURPOSE: To evaluate anatomic variations and pitfalls of the labral-capsular-ligamentous complex in the shoulder joint for the proper interpretation of magnetic reasonance arthrographic images. MATERIALS AND METHODS:To determine the presence of sublabral sulci, undercutting of the base of the glenoid labrum by the articular cartilage, and the proximity of the middle glenohumeral ligament to the anterior glenoid labrum, 56 MR arthrograms of 41 asymptomatic volunteers were prospectively evalvated for labral shape and capsular insertion. We also evaluated the axillary fold, which was often confused with a loose body. RESULTS: The anterior and posterior parts of the labra, varied but their shape showed several dominant features; triangular(72%, 36%, respectively), rounded(13%, 35%), cleaved(8%, 1%), notched(2%, 0%), flat(5%, 24%), and absent(0%, 4%). Anterior capsular insertion was type 1 in 82% of cases, type 2 in 13% and type 3 in 5%, whereas posterior insertion was type 1 in 62%, type 2 in 36% and type 3 in 2%. We could also detect many pitfalls, such as undercutting of the base of theglenoid labrum by the articular cartilage(29%), sublabral sulci(25%), a prominent axillary fold(38%), and the middle glenohumeral ligament in proximity to the anterior labrum(5%). CONCLUSION: Our study revealed wide variability in the MR arthrographic appearance of the labral-capsular-ligamentous complex in asymptomatic shoulders. A good understanding of normal variation and pitfalls of the normal shoulder may be helpful pathologic condition in case of glenouhumeral instability.

Journal of the Korean Radiological Society 2003;49(2):131-135
PURPOSE: To evaluate serial ultrasonographic findings of fungal myositis in children. MATERIALS AND METHODS: Eleven lesions caused by fungal myositis and occurring in six children were included in this study. Eight lesions in five children were histopathologically proven and the other three were clinically diagnosed. Serial ultrasonographic findings were retrospectively evaluated in terms of size, location, margin, internal echotexture and adjacent cortical change occurring during the follow-up period ranging from five days to two months. RESULTS: Three patients (50%) had multiple lesions. The sites of involvment were the thigh (n=4), calf (n=3), chest wall (n=2), abdominal wall (n=1) and forearm (n=1). Initially, diffuse muscular swelling was revealed, with ill-defined hypoechoic lesions confined to the muscle layer (n=8). Follow-up examination of eight lesions over a period of 5-10 days showed that round central echogenic lesions were surrounded by previous slightly echogenic lesions (n=6, 75%). Long-term follow-up of five lesions over a two-month period revealed periosteal thickening in one case (20%), and the peristence of echogenic solid nodules in four (80%). Pathologic examination showed that the central lesions correlated with a fungus ball and the peripheral slightly echogenic lesions corresponded to hematoma and necrosis. CONCLUSION: Serial ultrasonographic findings of fungal myositis in children revealed relatively constant features in each case. In particular, the findings of muscular necrosis and a fungus ball over a period of 5-14 days were thought to be characteristic.

BACKGROUND: Asymptomatic vancomycin-resistant enterococci (VRE) colonization precedes infection. VRE-colonized patients serve as silent reservoirs of enterococci that go on to colonize other patients. Rapidly identifying colonized patients is crucial to prevent the spread of VRE. The culture-based method of VRE screening is time-consuming. We evaluated the diagnostic performance of a recently developed multiplex real-time PCR for the detection of VRE. METHODS: We obtained 105 rectal swabs from patients who were being monitored for carriage of VRE. After 24 hour incubation of swabs in enterococcosel broth (EB) supplemented with 6 microg/mL vancomycin, multiplex real-time PCR was performed using the Anyplex(TM) VanR Real-time Detection (VanR) kit (Seegene, Inc., Seoul, Korea). The results of multiplex real-time PCR were compared to those of culture. We evaluated the specificity and detection limits of multiplex real-time PCR using VanR for VRE. RESULTS: A total of 96/105 (91.4%) samples were VRE positive according to multiplex real-time PCR with EB while 85/105 (80.9%) samples were positive in culture. Eleven discordant results (10.4%) (multiplex real-time PCR positive, culture negative) were noted. All non-enterococcal bacteria and vancomycin-susceptible enterococci were negative. The DNA detection limits of VanR were 0.035 pg per reaction (3 microL) for Enterococcus faecium and 0.35 pg for Enterococcus faecalis. CONCLUSION: The application of multiplex real-time PCR after EB incubation allows rapid and sensitive detection in 26-28 hours for VRE screening from rectal swabs. This method could facilitate the timely implementation of contact isolation to prevent the spread of VRE.

BACKGROUND: The cardiac troponin I (cTnI), one of the subunits of the troponin regulatory complex, binds to actin and inhibits interactions between actin and myosin. cTnI is highly sensitive and specific marker for myocardial injury and is useful in diagnosis and detection of reperfusion in acute myocardial infarction (AMI). In this study, we measured the serum concentration of cTnI according to serial time after chest pain in patients with AMI and compared serum concentration of cTnI with CK-MB and echocardiographic data to evaluate the significance of measuring serum concentration of cTnI in AMI. SUBJECTS AND METHODS: The study was carried out on 16 patients with first attack of AMI within 6 hours of chest pain. All patients were performed thrombolytic therapy and reperfusion was confirmed by coronary angiography. Blood samples for measuring of CK-MB and cTnI were collected at 4-h intervals during the first 24 h, 12-h intervals until 48 h, and 24-h intervals until fourth days after hospitalization. Echocardiography were performed before thrombolytic therapy in all patients. RESULTS: 1) The mean age of subjects was 63.6+/-11.5 years (range:44 - 84 years) and 11 patients were men and 5 patients were women. The site of infarction was anterior in 11 patients and inferior in 5 patients. 2) The peak concentrations of CK-MB and cTnI were reached from 4-h to 12-h after admission in all patients (7.3+/-2.6-h, and 9.0+/-3.1-h, respectively), but there was no significant difference in peak time. 3) Serum concentration of CK-MB was normalized at 72-h after admission, but cTnI was remained in increased state until 96-h after admission. The numbers of the patients with above cutoff value of CK-MB and cTnI at different time after admission were significantly different after 72-h (p<0.05). 4) The peak cTnI and sigma cTnI level were significantly correlated with peak CK-MB and sigma CK-MB level, respectively (r 2 =0.7955, p<0.0001 and r 2 =0.6378, p=0.0002, respectively). 5) The ejection fraction was not correlated with peak cTnI concentration (r 2 =0.0948, p=0.2461) and sigma cTnI (r 2 =0.1867, p=0.0946). 6) The wall motion score index was not correlated with peak cTnI concentration (r 2 =0.2135, p=0.0716), but significantly correlated with sigma cTnI (r 2 =0.2540, p=0.0465). CONCLUSION: The serum concentration of cTnI was useful in late diagnosis of AMI and cTnI release in patients with AMI was correlated with myocardial infarct size.
