Background and Objectives:
Cardiac resynchronization therapy (CRT) is an effective treatment for heart failure. However, in pediatric and congenital heart disease (CHD) patients, current adult indications cannot be directly applied because of heterogeneity in anatomy and diagnosis. Therefore, CRT responses and clinical outcomes in these patients were investigated to derive possible candidates for CRT.
Methods:
This study retrospectively analyzed 16 pediatric and CHD patients who underwent CRT implantation at a single center in early (0.7±0.2 year) and late (4.7±0.3 years) follow-up period after CRT.
Results:
The median age at CRT implantation was 2.5 (0.3–37.2) years, and median follow-up duration was 6.3 (0.1–13.6) years. Thirteen had non-transvenous CRT. Two had congenital complete atrioventricular (AV) block with previous right ventricular pacing, 5 had dilated cardiomyopathy (DCM) with left bundle branch block, and 9 had CHD. The mean ejection fraction of the systemic ventricle increased from 28.1±10.0% to 44.3±21.0% (p=0.003) in early and 51.8±16.3% (p=0.012) in late outcome. The mean functional class improved from 3.1±0.9 to 1.8±1.1 after CRT (p=0.003). Twelve patients (75%) showed improvement in ventricular function or functional class after CRT. Proportion of responders differed between patients without CHD (2/2 patients with complete AV block and 5/5 with DCM, 100%) and those with CHD (5/9, 56%), although statistical significance was not reached (p=0.088).
Conclusions
CRT improved ventricular function and functional status according to the underlying condition in pediatric and CHD patients. However, further large and longer-term studies are needed to establish the guideline for the patient selection of CRT in these patients.

Ocular symptoms related to orbital fracture occur immediately after the fracture in most cases. However, authors experienced a delayed onset diplopia occurred 16 months after orbital floor fracture. A 19-year-old man, who had right orbital floor fracture 16 months ago, presented with diplopia of upward gaze. At the time of the fracture, no surgery was performed because the fracture was minimal and there were no particular symptoms. Physical examinations revealed a minor ocular motility restriction of upward gaze, but orbital floor showed no definite interval change on computed tomography. Severe adhesion between the orbital fat tissue and orbital floor was noted intraoperatively and the adhesion was dissected. After the operation, the patient showed remarkable improvement in diplopia and restriction of the ocular motility.

In 2009, the novel swine H1N1 influenza (SI) virus infection had been pandemic and in some patients it led to death. But autopsy findings with pathologic features have been rarely known in the deceased with the SI infection. Herein we presented the findings in three deceased cases with the infection of SI virus, compared with those of other literatures. In all cases, postmortem examination with legal autopsy was done due to sudden unexpected death. SI virus infection was confirmed by detection of SI viral RNA performed on Korea center for Disease Control and Prevention. The autopsy findings with pathologic features of our cases were similar to those of the cases on other reports and those of previous pandemic influenza virus infection on literatures. And these findings may be helpful for understanding the biology of SI virus, and for diagnosis, treatment, and prevention of the SI infection.

Cerebral cavernous angioma is a rare form of vascular malformations which is histologically composed of closely-packed, thin-walled blood vessels without neural tissue intervened. One of the most common symptoms is seizure, which is usually well-controlled by medication or surgery and known to be rarely intractable or fatal. Because sudden, unexpected death in epilepsy patients reveals generally its unclear death mechanism and negative autopsy finding in forensic pathology practice, particular attention should be paid. We recently experienced an autopsy case of 32-year-old woman who had suffered from epilepsy and showed cerebral cavernous angioma on autopsy. We report this case with literature review.

Alzheimer's disease is the leading cause of dementia. We experienced a case of Alzheimer's disease who is 83-year-old woman killed by stab with a knife. She had been suffered from dementia for several years. At autopsy, the brain disclosed cortical atrophy in the frontal, temporal and parietal lobes, and hippocampus. Microscopically, many senile plaques and a few neurofibrillary tangles were observed at the cerebral cortex and hippocampus. Senile plaques were characterized by a spherical structure with or without a dense central core of amyloid, associated with dystrophic neurites. Neurofibrillary tangle was an intracellular filamentous lesion in the cell body of neuron. To our knowledge, this is a rare autopsy case in Korea, therefore, we report here-in and review the clinicopathologic features of Alzheimer's disease.

Episodic ataxia type 2 (EA 2) is a rare disorder characterized by intermittent episodes of ataxia with interictal nystagmus. The authors report a patient with EA 2, who presented with recurrent episodes of vertigo, gait ataxia and interictal downbeat nystagmus, which had developed about 16 years before. The chromosomal analysis revealed a translocation between chromosome 7 and chromosome 19 (t(7;19)). The break point in chromosome 19 was the P13 locus of the CACNA1A gene.

BACKGROUND: The purpose of this study is to evaluate balance functions as one ages using the values of the sensory organization test (SOT) and the motor control test (MCT) of computerized dynamic posturography (CDP) in healthy Korean adults. METHODS: We studied the equilibrium scores of the SOT and weight symmetries, latencies, and adaptation scores of the MCT in 72 healthy Korean adults. Subjects were divided into three age groups, the 30's (young group), 50's (middle-aged group), and 70's (elderly group). RESULTS: In the SOT, the range of mean equilibrium scores was from 69.8 to 94.2 in the 3rd decade group, 62.6 to 93.8 in the 5th decade group, 59.2 to 91.2 in the 7th decade group. In the MCT, during sudden anterior and posterior perturbations, the weight symmetries were 101.1 +/- 7.5 in the 3rd decade group, 103.6 +/- 6.9 in the 5th decade group, and 106.4 +/- 9.4 in the 7th decade group. The mean latencies were 123.6-132.8 msec in the 3rd decade group, 130.5-138.5 msec in the 5th decade group, 132.7-141.8 msec in the 7th decade group. CONCLUSIONS: Almost all measures of balance were significantly worse in the elderly group compared with the young group and some changes of balance were observed in the middle-aged group as well. These significant age-associated declines of balance function suggested the decreased capacity to process sensory inputs in aged persons. This occurs most likely as a result of biomechanical or central processing changes.

8.Juvenile Pompe Disease with CNS Involvement: A Case Report.
Korean Journal of Legal Medicine 2003;27(1):92-95
Pompe disease (Glycogenosis type 2) is an autosomal recessive glycogen storage disorder by deficiency of lysosomal acid alpha-glucosidase. The disorder encompasses a range of phenotypes, each including myopathy but differing in age of onset, organ involvement, and clinical severity. Glycogen storage is most prominent in skeletal and cardiac muscle, and liver. The authors described a 8-year-old girl who presented hypotonia, mental retardation and hepatomegaly, and died accidentally of burn. Light and electron microscopic examination on autopsied tissue revealed diffuse both cytoplasmic and lysosomal glycogen storage in hepatocytes, neurons of cerebral cortex and hippocampus, and renal tubular epithelium. A few cases of Pompe disease with CNS involvement has been reported in English literature previously. Nevertheless, to our knowledge, it is the first time in Korea.

The Kawasaki disease(Mucocutaneous lymph node syndrome) has been reported worldwide since the first description in 1967 in Japan. Approximately 20% of the children with untreated Kawasaki disease are believed to develop coronary artery aneurysm of which 2-3% progress to coronary artery stenosis. The early mortality of Kawasaki disease is low, resulting from coronary complications, mainly aneurysmal thrombosis with myocardial infarction. The purpose of this article is to report three cases of sudden deaths who died of cardiac sequelae of Kawasaki disease. Case 1 was a 9 year old male who died of cardiac tamponade caused by ruptured left coronary artery with features of vasculitis and aneurysmal dilatation. Case 2 was a 20 year old male who had been healthy and died suddenly and unexpectedly. At autopsy, the heart showed cardiomegaly and coronary artery aneurysm with thrombus and stenosis. Case 3 was a 10 year old male who was asymptomatic. At autopsy, the heart showed coronary artery lesions including aneurysm, fibrous thickening, and calcification, and myocardial fibrosis. According to the Classification of Kawasaki disease, case 1 was considered Stage I, and cases 2 and 3 Stage IV.

BACKGROUND: Tamoxifen (TAM) inhibits the action of estrogen by binding to estrogen receptors, and also has non-estrogen receptor mediated cytostatic activities. Transforming growth factor-1 (TGF-1) inhibits the proliferation of many other cell types, such as epithelial, hematopoietic and endothelial cells. METHODS: We investigated the effects of tamoxifen on the growth of 7,12-dimethylbenz(a)anthracene (DMBA)-induced rat mammary tumors and the expression of cyclin D1, cyclin E, p21Cip1, and p27Kip1 by performing immunohistochemistry and Western blot analysis, and studied whether TGF-1 injection amplified the effects of TAM. When tumor size reached between 10-15 mm in the largest dimension, the rats were divided into 3 groups: DMBA-control group (n=12), DMBA-TAM group (n=14) and DMBA-TAM plus TGF-1 group (n=5). RESULTS: The consecutive administration of TAM markedly decreased the tumor development compared with the DMBA-control group. The DMBA-TAM and DMBA-TAM plus TGF-1 groups showed decreased expression of bromodexoyuridine, cyclin D1, cyclin E, and p21Cip1 when compared with those of the DMBA-control group. On the other hand, the labeling index of p27Kip1 was higher in the DMBA-TAM plus TGF-1 group than in the DMBA-control group. CONCLUSION: TAM suppresses tumor development, which may be associated with down-expression of cyclin D1 and cyclin E, and overexpression of p27Kip1, and addition of TGF-1 does not influence tumor development treated by TAM.
