Kawasaki disease or mucocutaneous lymph node syndrome is an acute inflammatory illness of childhood characterized by systemic panvasculitis. It presents with high fever, dramatic changes of the skin and mucous membranes, and lymphadenopathy. Adult-onset Kawasaki disease is rare and reports on coronary involvement in adult are even rarer. Herein, we report a case of adult-onset Kawasaki disease complicated by splenic infarction and development of coronary aneurysm even despite of treatment with intravenous gamma globulin. A 20-year-old man presented with fever, erytheatous rash, induration and desquamation of hands and feet, pulmonary edema and shock due to cardiomyopathy, splenic infarction, bilateral conjunctivitis, jaundice, and cervical lymphadenopathy. After Kawasaki disease was suspected, intravenous gamma globulin (2 g/kg once) and aspirin (6 g/day) were administered. On the 30th hospital day, transesophageal echocardiography showed one coronary aneurysm and coronary angiography showed three aneurysms. Eight months after the first admission, follow-up coronary angiography showed normalization of the previous coronary abnormalities.

The indications and applications of arthroscopic surgery for the knee joint have increased with the development in surgical techniques and the improvement of arthroscopic equipment. The use of arthroscopic surgery has led to a significant decrease in morbidity for the patient with intra-articular abnormalities, in terms of both the diagnosis and the surgical treatments. Even though arthroscopy is a minimally invasive technique with relatively low morbidity, it is not without risk of complications, of which neurovascular complications are among the most serious and devastating. Here we report on 2 cases of popliteal artery injury during arthroscopic knee surgery and its specific diagnosis and treatment.

Osteogenesis imperfecta is a rare congenital disease. It is a heterogeneous group of inherited disorders characterized by multiple bone fracture, blue sclera, hearing loss, abnormalities of dentition and widespread connective tissue ahnormality. We experienced a case of osteogenesis imperfecta diagnosed in utero by ultrasonogram and confirmed hy postnatal radiograph after delivery. We present the case with a hrief review of the literature.

Cardiogenic dysphagia is a rare type of esophageal dysphagia caused by external compression of the esophagus by an enlarged left atrium. Long-term comparisons between the degree of cardiogenic dysphagia and heart failure have not been reported due to its low incidence. We hereby report the case of a 74-year-old woman with valvular heart disease, suspected of having oropharyngeal dysphagia following a recent intracerebral hemorrhage, who performed a swallowing function test. Videofluoroscopic swallowing study (VFSS) revealed a supraglottic penetration, confirming the oropharyngeal dysphagia. Furthermore, post-VFSS chest radiograph revealed esophageal residual barium, suggestive of reduced esophageal food transition secondary to external compression, at the level of the T6 vertebral body. Chest computed tomography showed mid-esophageal compression caused by left atrial enlargement. She had pulmonary edema which was managed with diuretics. Post-VFSS chest radiographs also revealed a direct association between the diameter of the esophageal barium residue and body weight. A reduction in body weight led to the resolution of the barium residue and vice versa. Development of cardiac dysphagia may be one of the signs of acute exacerbation of heart failure.

Dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) is an acute febrile illness characterized by hemorrhagic phenomenon and hypovolemic shock due to increased vascular permeability and plasma leakage in patients infected with any one of four serotypes of dengue virus. The disease is one of the principal causes of hospitalization and death among children in several south-east Asian, central and south American, and African countries. With increasing use of air or ship transport, more travelers and sailors to the tropics are returning within the incubation period of acute febrile infection. Herein we reported the first Korean case of dengue hemorrhagic fever imported from Africa. We experienced a Korean sailor who complains of fever, chill, nausea, and epistaxis after the return from Mombasa, Kenya. His fellows also showed the similar complains. His illness improved spontaneously and the indirect immunofluorescent antibody testing revealed antibody titer of 1:1024 or more.

The Immunological diagnosis of tuberculous meningitis (TBM) requires the presence of de novo synthesis of immunoglobulin in the central nervous system. We investigated the CNS IgG synthetic rate and IgG antibody titers against lipoarabinomanan (LAM) and PPD antigens in the serum and CSF by using ELISA in patients with TBM and patients with only pulmonary tuberculosis (PTB). The CNS IgG synthetic rate was markedly increased in all 11 patients with TB with PTB (56.42+l886 mg/day vs 7.47+435 mg/day). On the other hand, abnormally elevated IgG titers in the CSF against either LAM or PPD antigen were present in all 7 patients with TBM and in 4 of 11 patients with PTB tested. The 4 patients with the false positivity showed markedly elevated IgG antibody titers in the sera suggesting the passive diffusion of IgG antibodies through the intact blood brain barrier from the sera to the CSF. It is likely that the simultaneous measurement of CNS IgG sythesis is an useful addition to the ELISA of IgG antibody titration against the antigens of M. tuberculare in the CSF for the accurate diagnosis of TBM, especially in the endemic area of tuberculosis.

A 36-year-old women visited hospital with right pleuritic chest pain. Chest X-ray showed right pleural effusion. Hematological examination revealed eosinophilia in peripheral blood (28%) and pleural effusion (90%). ELISA (enzyme-linked immunosorbent assay) for serum parasite-specific IgG antibody was negative. We examined HRCT and thoracoscopic pleural biopsy, but didn't find out the cause of pleural effusion. We found out Toxocara canis excretory-secretory IgE ELISA was positive. One month later, multiple nodular shadows appeared in left upper lung field. We reexamined ELISA for serum Paragonimus westermani IgG antibody, and the result was positive. She was treated with praziquantel for 2 days, and then the lung lesions and pleuritic chest pain disappeared. We report here P. westermani infection in a patient whose serum was negative for the specific IgG antibody by ELISA at earlier stage but became positive later, and whose serum was also positive for Toxocara canis.

BACKGROUND AND OBJECTIVES: The impact on long-term adverse cardiac events of troponin T (TnT) or creatine kinase-MB (CK-MB) release after percutaneous transluminal coronary angioplasty (PTCA) is not well defined. The purpose of the study is to evaluate the effect of elevated TnT or CK-MB on the late major adverse cardiac events [MACE ; Q wave myocardial infarction (MI), revascularization, or cardiac death]. SUBJECTS AND METHODS: Study population were 207 consecutive patients (M : F=148 : 59, mean 60.8+/-9.2 years) who underwent PTCA. Patients with acute MI, unstable angina with abnormal levels of TnT or CK-MB, or newly developed Q MI after PTCA were excluded. Cardiac enzyme levels were measured before and 8, 24 hours after PTCA for CK-MB, and before and 16 hours after PTCA for TnT. Group I (n=181, 87.4%) had normal levels of both after PTCA. Group II (n=26, 12.6%) had abnormal levels of CK-MB (>or=16 U/L) and/or TnT (>or=0.2 ng/mL). 1-year follow-up was available in 201 (97.1%) patients. RESULTS: Incidence of non-Q MI after PTCA was 26/207 (12.6%). Major complications such as acute coronary occlusion, side branch occlusion, and major dissection were significantly associated with elevation of TnT or CK-MB after PTCA (p=0.01). However, elevation of CK-MB or TnT was not significantly associated with late MACE by Kaplan-Meier survival curve (p=0.46). During 1-year follow-up, event free rate of group I and II were 76.6% and 69.2%, respectively. CONCLUSION: Acute coronary occlusion, side branch occlusion, or major dissection can increase the level of TnT or CK-MB after PTCA. But, elevation of CK-MB or TnT after PTCA dose not significantly influence on late MACE.

Regulation of osteoblast and osteocyte viability is essential for bone homeostasis. Smad4, a major transducer of bone morphogenetic protein and transforming growth factor-β signaling pathways, regulates apoptosis in various cell types through a mitochondrial pathway. However, it remains poorly understood whether Smad4 is necessary for the regulation of osteoblast and osteocyte viability. In this study, we analyzed Smad4Δ(Os) mice, in which Smad4 was subjected to tissue-specific disruption under the control of the 2.3-kb Col1a1 promoter, to understand the functional significance of Smad4 in regulating osteoblast/osteocyte viability during bone formation and remodeling. Smad4Δ(Os) mice showed a significant increase in osteoblast number and osteocyte density in the trabecular and cortical regions of the femur, whereas osteoclast activity was significantly decreased. The proliferation of osteoblasts/osteocytes did not alter, as shown by measuring 5′-bromo-2′deoxyuridine incorporation. By contrast, the percentage of TUNEL-positive cells decreased, together with a decrease in the Bax/Bcl-2 ratio and in the proteolytic cleavage of caspase 3, in Smad4Δ(Os) mice. Apoptosis in isolated calvaria cells from Smad4Δ(Os) mice decreased after differentiation, which was consistent with the results of the TUNEL assay and western blotting in Smad4Δ(Os) mice. Conversely, osteoblast cells overexpressing Smad4 showed increased apoptosis. In an apoptosis induction model of Smad4Δ(Os) mice, osteoblasts/osteocytes were more resistant to apoptosis than were control cells, and, consequently, bone remodeling was attenuated. These findings indicate that Smad4 has a significant role in regulating osteoblast/osteocyte viability and therefore controls bone homeostasis.
