BACKGROUND: Pulmonary thromboembolism is relatively frequent and potentially fatal. However, it is commonly misdiagnosed. The incidence of pulmonary thromboembolism is not decreasing despite advances in diagnosis and effective prophylatic measures. Its potential for significant sequela necessitates a prompt diagnosis and treatment. Unfortunately, there are many difficulties and problems regarding accurate diagnosis. There is a low prevalence of deep vein thrombosis and pulmonary thromboembolism in Korea and only few reports on this subject are available. METHOD: The clinical features of 36 patients, who were diagnosed with pulmonary thromboembolism at the Korea University medical center, were reviewed. RESULTS: 1) There was no significant difference in prevalence between men an women, and the mean age was 50.9 years in men 59.2 years in women. 2) The frequent causes of pulmonary thromboembolism were malignancies (22.2%), surgery (22.2%), and heart disease(8.2%). Specific causes were not identified in 33.3%. 3) The most common symptom was dyspnea(72.2%), and the most common sign was tachypnea(61.1%). 4) The EKG findings were normal in 28.6%, and S1Q3T3 pulmonale pattern in 25.7%, ST or QRS changes in others. 5) The chest X-ray findings indicated pulmonary infiltation in 37.5%, cardiomegaly in 15.6%, pleural effusion in 12.5%, and normal in 27.8%. The perfusion lung scan showed a high probability in 66.7%, and intermediate or low probability in 33.3%. 6) The pulmonary arterial pressure(PAP) in the high probability groups was 57.9mmHg with a higher mortality rate(35%). CONCLUSION: Pulmonary thromboembolism is not uncommon in Korea and its clinical features do not differ greatly from those reported in the literature. When pulmonary thromboemblism of unknown causes are diagnosed, a search for an occult malignancy is recommended. Rapid diagnosis and treatment are achieved when thromboemblism is suspected.

A 20-year-old woman was admitted because of intractable seizures, myoclonus, gait ataxia, and severe intellectual deterioration with age of onset at 16 years. She had no family history of neurological disease. A thorough laboratory investigation was unremarkable. Brain MRI showed generalized cerebral and cerebellar atrophy. Interictal EEG showed intermittent generalized polyspike and waves, maximum on the bilateral parieto-occipital areas, and MNSEP showed giant cortical SEP. Brain biopsy revealed intraneuronal accumulation of granular osmiophilic deposits (GROD), which is characteristic of electromicroscopic findings of neuronal ceroid lipofuscinosis (NCL). We report biopsy-proven adult NCL, which is one of the rare neurodegenerative diseases. (J Korean Neurol Assoc 19(1):45~48, 2001

BACKGROUND AND OBJECT: Immunostimulatory CpG-oligodeoxynucleotides (ISS CpG-ODN) up-regulate the TH1-type immune response and down-regulate the TH2-type response. This study was performed to investigate the immune response changes resulting from ISS CpG-ODN on bronchial hyperrestponsiveness, eosinophilic inflammation and mucus hypersecretion in rat asthma. MATERIALS AND METHODS: 10 normal controls(NC) and 26 asthmatic rats, which were generated by ovallbumin(OVA) sensitization and challenge, were studied. The asthmatic rats were randomized into 11 asthma controls(AC) and 15 in the asthma-CpG treatment group(CpG). The CpG group was administered ISS CpG-ODN intramuscularly and the AC group was administered a placebo(0.9% NaCl)on day 15 and 20. After CpG-ODN or placebo administration, we measured the IFN-(TH1-type cytokine) and IL-4(TH2-type cytokine) levels in the bronchoalveolar lavage fluid(BALF), the specific airway resistance(sRaw), eosinophilic fraction in BALF, eosinophilic infiltration, goblet cell dysplasia and MUC5AC gene expression in the lung tissue. RESULTS: In the BALF of the CpG group, the IFN-γ concentration was significantly high and the IL-4 concentration was significantly low when compared with the AC group. Both the sRaw and eosinophilic fraction, and infiltration into the BALF and lung tissue significantly lower in the CpG group when compared with the AC group. However, little difference in goblet cell dysplasia and MUC5Ac gene expression was observed between the CpG group and the Ac group. CONCLUSION: ISS CpG-ODN decreases bronchial hyperresponsiveness and eosinophilic inflammation in the rat asthma model through the up-regulation of the TH1-type immune response with the down-regulation of the TH2-type response. However, the effect of these immune response changes on mucus hypersecretion was is not remarkable in this study.

BACKGROUND: The dominant innervation of airway smooth muscle is parasympathetic fibers which are carried in the vagus nerve. Activation of these cholinergic nerves releases acetylcholine which binds to M3 muscarinic receptors on the smooth muscle causing bronchocontraction. Acetylcholine also feeds back onto neuronal M2 muscarinic receptors located on the postganglionic cholinergic nerves. Stimulation of these receptors further inhibits acetylcholine release, so these M2 muscarinic receptors act as autoreceptors. Loss of function of these M2 receptors, as it occres in animal models of hyperresponsiveness, leads to an increase in vagally mediated hyperresponsiveness. However, there are limited data pertaining to whether there are dysfunctions of these receptors in patients with asthma. The aim of this study is to determine whether there are dysfunction of M2 muscarinic receptors in asthmatic patients and difference of function of these receptors according to severity of asthma. METHODS: We studied twenty-seven patients with asthma who were registered at Pulmonology Division of Korea University Hospital. They all met asthma criteria of ATS. Of these patients, eleven patients were categorized as having mild asthma, eight patients moderate asthma and eight patients severe asthma according to severity by NAEPP Expert Panel Report 2(1997). All subjects were free of recent upper respiratory tract infection within 2 weeks and showed positive methacholine challenge test(PC 20<16mg/ml). Methacholine provocation tests performed twice on separate days allowing for an interval of one week. In the second test, pre-treatment with the M2 muscarinic receptor agonist pilocarpine(180µg) through inhalation was performed before the routine procedures. RESULTS: Eleven subjects with mild asthma and eight aubjects with moderate asthma showed significant increase of PC20 from 5.30±5.23mg/ml(mean±SD) to 20.82±22.56mg/ml(p=0.004) and from 2.79±1.5mg/ml to 4.67±3.53mg/ml(p=0.012) after pilocarpine inhalation, respectively. However, in the eight subjects with severe asthma significant increase of PC20 from 1.76±1.50mg/ml to 3.18±4.03mg/ml(p=0.161) after pilocarpine inhalation was not found. CONCLUSION: In subjects with mild and moderate asthma, function of M2 muscarinic receptors was normal, but there was a dysfunction of these receptors in subjects with severe asthma. These results suggest that function of M2 muscarinic receptors is different according to severity of asthma.

Huge hepatic cysts are rarely encountered in autosomal dominant polycystic kidney disease. Huge hepatic cyst bothers the patient either by compression or complications such as intracystic infections or hemorrhages. We report, here, alcohol instillation to treat a huge hepatic cyst causing compression symptom with improvement in size & symptom. A 49-year-old female patient presented with a 4-week history of indigestion and epigastric discomfort. Physical examination was remarkable for tender hepatomegaly. Computerized tomography revealed huge hepatic and kidney cysts. Ultrasonographic guided percutaneous drainage and four times alcohol sclerotherapy of the huge heptic cyst was successful. Relief of the symptoms was maintained after 18 days. This case shows that alcohol sclerotherapy can be a effective nonsurgical method of treating symptomatic huge hepatic cysts.

Carcinoma of lung is classified by histologic cell type, this is based on predominant major cell population by tissue specimen. But in fact a range of 13% to 63% of lung cancer has been appeared to be heterogeneous cell type at the light microscopic level. After treatment of the mixed lung cancer and/or with time there are reports that cell type is changed. Because it is possible that the tumor were pleomorphic and that the antitumor therapy eliminated the more sensitive cell population and permitted the subsequent emergence of the more resistant cell population. The authors reported here, a case of 32 year old female patient with mixed lung cancer composed of three cell type, and this is the first case in Korea.
