PURPOSE: We compared the clinical manifestations of patients with tsutsugamushi disease between children and adults. METHODS: From January 2003 to December 2012, 768 patients diagnosed with tsutsugamushi disease were retrospectively reviewed, and the clinical characteristics, laboratory findings, and complications were compared between children and adults. RESULTS: No patterns of annual increases in the number of patients were noted in both children and adults. The higher incidences occurred in October and November respectively. By gender, male outnumbered female in children, but the opposite trend was seen in adults. By residential area, the urban distribution of children was higher than that of adults. Rashes (P=0.001) and eschar (P=0.004) were more common in children, while myalgia was more common in adults. Children had a high prevalence of anemia (P=0.041), and low incidence rates of thrombocytopenia, abnormal liver and renal function. Children yielded better results in the duration of their hospital stay and the incidence of complications (P<0.001). A comparison of the therapeutic effects of doxycycline and macrolide antibiotics, which was performed only on the children, did not reveal any significant differences. CONCLUSION: Compared to adults, children had higher incidence rates of male patients and more often suffered from rashes and eschar. Children yielded better results in the laboratory findings and duration of the hospital stay and complications. Therefore, when children are suspected to have tsutsugamushi disease, especially during its peak occurrence period, detailed physical examination and serological test should be performed to ensure a prompt diagnosis, and the use of macrolide antibiotics, which have fewer side effects, is expected to yield the same therapeutic effects.

Background:
The main cause of death in pulmonary embolism (PE) is right-heart failure due to acute pressure overload. In this sense, extracorporeal membrane oxygenation (ECMO) might be useful in maintaining hemodynamic stability and improving organ perfusion. Some previous studies have reported ECMO as a bridge to reperfusion therapy of PE. However, little is known about the patients that benefit from ECMO.
Methods:
Patients who underwent ECMO due to pulmonary thromboembolism at a single university-affiliated hospital between January 2010 and December 2018 were retrospectively reviewed.
Results:
During the study period, nine patients received ECMO in high-risk PE. The median age of the patients was 60 years (range, 22–76 years), and six (66.7%) were male. All nine patients had cardiac arrests, of which three occurred outside the hospital. All the patients received mechanical support with veno-arterial ECMO, and the median ECMO duration was 1.1 days (range, 0.2–14.0 days). ECMO with anticoagulation alone was performed in six (66.7%), and ECMO with reperfusion therapy was done in three (33.3%). The 30-day mortality rate was 77.8%. The median time taken from the first cardiac arrest to initiation of ECMO was 31 minutes (range, 30–32 minutes) in survivors (n=2) and 65 minutes (range, 33–482 minutes) in non-survivors (n=7).
Conclusion
High-risk PE with cardiac arrest has a high mortality rate despite aggressive management with ECMO and reperfusion therapy. Early decision to start ECMO and its rapid initiation might help save those with cardiac arrest in high-risk PE.

BACKGROUND AND OBJECTIVES: Undiagnosed diabetes mellitus (DM) or impaired glucose tolerance (IGT) is not uncommon in patients with coronary atherosclerosis and is known to be associated with abnormal scores for atherosclerosis surrogates. We sought to determine the prevalence of undiagnosed DM or IGT, and the association between insulin resistance (IR) and atherosclerosis surrogates in patients with coronary atherosclerosis. SUBJECTS AND METHODS: The study population consisted of 187 consecutive patients with angiographically proven coronary atherosclerosis (mean: 61 years old, 94 males). We measured carotid intima-media thickness (IMT) and flow mediated brachial artery dilatation (FMD). We also did oral glucose tolerance tests (OGTT), quantitative insulin-sensitivity check indexes (QUICKI) and homeostasis model assessment-IR (HOMA-IR). RESULTS: Abnormal OGTT was found in 164 patients (87.7%), even though there were only 63 known cases of DM (33.7%). There were 58 patients (31%) with newly diagnosed IGT and 43 patients (23%) with newly diagnosed DM. There were 71 patients (38%) who had IR (defined as measured HOMA-R > or =3.0). HOMA-IR showed a positive correlation with body mass index (BMI) (r=0.275, p<0.001) and triglycerides (r=0.2, p=0.01), whereas QUICKI had a negative correlation with BMI (r=-0.26, p<0.001), total cholesterol (r=-0.15, p=0.04), triglycerides (r=-0.21, p=0.004) and low-density lipoprotein-cholesterol (LDL-C) (r=-0.17, p=0.02). HOMA-IR and QUICKI were not significantly correlated with IMT or FMD. CONCLUSION: This study suggests that there is a high incidence of undiagnosed DM and IGT, but atherosclerosis surrogates are not associated with IR in patients with coronary atherosclerosis.

BACKGROUND AND OBJECTIVES: While the clinical significance of descending thoracic aorta intima-media thickness (DTA-IMT) remains unclear, common carotid IMT (CIMT) is known to be associated with major adverse cardiovascular events (MACE) in patients with atherosclerotic disease. SUBJECTS AND METHODS: A total of 104 patients (mean age, 59 yrs; 69 male) with angiographically proven coronary atherosclerosis underwent transesophageal echocardiography (TEE) for DTA-IMT measurement and carotid scanning for CIMT measurement. The patients were divided into two groups based on the median IMT value, and they were followed up for cardiovascular events and all-cause mortality for a period of 50+/-21 months. RESULTS: Patients having a higher DTA-IMT value (n=44, >2.1 mm) had a higher chance of stroke (6.7% vs. 2.8%, p=0.04), peripheral vascular disease (6.7% vs. 1.9%, p=0.02), and death (2.9% vs. 0%, p=0.04) than those who had lower DTA-IMT values (n=60, < or =2.1 mm). The patients who had higher CIMT values (n=49, >0.089 mm) had a higher chance of peripheral vascular disease (16% vs 2%, p=0.009) than those having lower IMT values (n=55, < or =0.089 mm). However, there was no significant difference between the groups in terms of recurrent chest pain, heart failure, syncope, myocardial infarction or chronic kidney disease during the follow-up period. Multivariate Cox regression analysis revealed that increased DTA-IMT was associated with stroke (OR, 4.29; 95% CI, 1.076-17.181; p=0.039) and peripheral vascular disease (OR, 9.37; 95% CI, 1.571-55.499; p=0.014), whereas increased CIMT was associated with peripheral vascular disease (OR, 14.365; 95% CI, 1.050-196.540; p=0.046). CONCLUSION: This study suggests that descending thoracic aorta IMT is more closely associated with prognosis in patients with coronary atherosclerosis than CIMT.

BACKGROUND AND OBJECTIVES: Increased carotid intima-media thickness (IMT) is known to be associated with adverse cardiovascular events in the patients with risk factors or established atherosclerosis. However, the prognostic importance of carotid IMT is uncertain in the patients who underwent percutaneous coronary intervention (PCI). We sought to evaluate the association of carotid IMT with major adverse cardiovascular events (MACE) and restenosis in the patients who underwent PCI. SUBJECTS AND METHODS: The study population consisted of 308 consecutive patients who underwent PCI, and they were followed up for mean of 30.6+/-13.3 months. Base on the median values of carotid IMT, which was measured in the right common carotid artery at the time of PCI with using high-resolution ultrasound and a semiautomatic method, the subjects were divided into the thick (n=156, 1.003+/-0.14 mm) and thin IMT (n=152, 0.748+/-0.07 mm) groups, and they were followed up for at least 1 year. RESULTS: Patients with thick carotid IMT were older (61+/-9 years vs. 57+/-10 years, respectively, p=0.001), had a higher body mass index (25.0+/-3.0 vs. 23.9+/-4.0, respectively, p=0.017), a history of previous myocardial infarction (20% vs. 9%, respectively, p=0.008), more multivessel disease and more restenosis (34.6% vs. 23.0%, respectively, p=0.025) than those patients with a thin carotid IMT. However other MACEs such as death, myocardial infarction, stroke, heart failure and target lesion revascularization did not show any significant differences between the two groups. Multivariate Cox regression analysis showed that carotid IMT was an independent predictor of restenosis (odds ratio: 1.754, 95% confidence interval: 1.1296 to 2.726, p=0.012). CONCLUSION: An increased carotid IMT is associated with restenosis, but it does not have clinical prognostic importance for the patients who underwent PCI during a mean follow up period of 31 months.

We present 2 cases of complicated mechanical thrombectomy involving tandem cervical internal carotid artery and middle cerebral artery occlusion using the Solitaire FR stent and simultaneous carotid stent angioplasty. During the procedures, the Solitaire stents containing the thrombus were wedged into the open-cell carotid stents, which were already deployed for proximal flow restoration. We describe the methods used to avoid and overcome such complications.
