Many patients whose chief complaint is headache caused by accident such as traffic accident, falling, or assaults visit to emergency center. Majority of these patients has mild or moderate symptoms, and there is no need to treat surgically. However, the fact that head injury can cause SIADH(syndrome of inappropriate secretion of antidiuretic hormone) is likely to be overseen. Acute hyponatremia might have been associated with death or permanent brain damage. Hyponatremia is best handled by early recognition and correction of a downward trend in the serum sodium. Unfortunately, this is often difficult in the head-injured patient, where hyponatremia may occur fairly rapidly and is confused by symptoms of head injury. when moderate to severe hyponatremia occurs, it is important to determine its etiology and expeditiously initiate corrective action. There has not been any reported case of the occurrence of symptomatic SIADH after mild head injury in Korea yet. The authors report the experience of three cases of symptomatic SIADH after mild head injury with review of the literatures.

To evaluate the effectiveness of computed tomography for the differential diagnosis of cervical lymphadenopathy, we reviewed CT scans of 26 patients with cervical lymphadenopathy retrospectively. These included 10 patients with tuberculous lymphadenitis, 11 patients with metastasis and 5 patients with lymphoma, We evaluated the CT scans with a special attention to internal nodal density, feature of contrast enhancement and location of lymphadenopathy. Tuberculous lymphadenitis involved multiple nodes unilaterally and showed central low density with even or uneven rim enhancement, usually occurring in young patients (mean: 31.6 years). Two cases with tuberculous lymphadenitis showed calcifications within the lymph nodes. Lymphoma involved unilateral or bilateral nodes and appeared as conglomerated isodense mass with even rim enhancement. Metastasis involved multiple nodes unilaterally and showed focal, diffuse of mixed pattern of central low density with variable rim enhancement, usually occurring in old patients (mean: 59.4 years). Locations of most frequent lymph node involvements were internal jugular group (76%), spinal accessory group (54%) and retropharyngeal group(12%).

The use of angiographic embolization gas been well described for the control of gynecologic bleeding. Recently, we have experienced the successful embolization in two case of serons bleeding related to giynecologic malignancy. Clinical evaluation revealed a gynecologic cancer with active bleeding. Becaause we judged that conservative management was unable to cuntrol the bleeding, we underwent an angiographic embolization. The result presented here indicates that angiographic embolization is a relatively safe, effective and rapid procedure that should be considered early in management of gynecohogic cancer bleeding that is unresponsive to conservative management.

BACKGROUND: Coal-worker's pneumoconiosis(CWP) is characterized by a chronic inflammatory lung reaction associated with macrophage accumulation in the alveolar spaces. CWP is usually divided into two stages : simpl e pneumoconiosis(SP) where there are a limited number of fibrotic lesions remain limited, with radiological opacities smaller than 1cm and progressine massive fibrosis(PMF), which is characterized by the development of a perifocal extensive fibrotix response of the lung and severws alterations in pulmonary function. In this study, the lymphocyte compartment and cytokine were evaluated by measuring the serum levels in the control, SP and PMF groups. METHODS: The coal workers selected for this study were employees(patients?) of the Tae-Baek and Dong-Hae hospital. All were men, 45-76 years old and the mean duration of their exposure to coal dust was 23.2 years in the lymphocyte compartment and 24.3 years in the cytokine checked group. According to the X-ray examination results, the patients were classified into either one of the SP, PMF categories. The normal controls examnied were 26-70 years old men. The serum cytokine levels were estimated by using an end point enzyme immunoassay technique. RESULTS: T lymphocyte, helper and suppressor T cells were highly related to pneumoconiosis in this study. A statistically significant decrease in the number of suppressor T lymphocytes was observed in this simple pneumoconiosis patients and at the same time, there was an increase in the lymphocyte index. However, there was no statistically defference in the serum cytokines levels among the SP, PMF and control groups. CONCLUSION: T lymphocyte, helper T, and suppressor T cells may be highly related to the development of CWP compared to the control group particularly in the early stage of pneumoconiosis. The changes obseved in the immunological system in patients with pneumoconiosis may lie at the bottom of the pathogenesis of fibrosis. Further study is needed to evaluated the lymphocyte compartment as a marker of pneumoconiosis developement in the early stage.

Arthropod antigens are main causative agents which induce allergic responses in humans. However, little information is known about the prevalence of specific arthropod allergens in Koreans with allergic diseases. The current study was designed to determine the positive rates of arthropod antibodies by the Korean inhalant panel of MAST-CLA. One hundred sixty patients, who were diagnosed with allergic rhinitis from an out-patient center at the Soonchunhyang University Chunan Hospital, were studied between August 1998 to July 2000. The overall positive rate, at least more than one specific antibody of arthropods such as Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), and cockroach mix (Cm), was 46.9%. Each positive rate of Df, Dp, and Cm was 45.0%, 43.1%, and 8.8%, respectively. A significant agreement among arthropod allergens was observed (Df and Dp: 95.6%, Kappa = 0.911, P < 0.001). Our data supported the fact that arthropods were the most common allergens in Korean patients with allergic rhinitis; however, the MAST-CLA should be modified to increase specificity of arthropod allergens.

Hypoxia is a serious aviation problem and can always be a source of dangerous aerospace accidents. Hypoxic chamber flight training used to evaluate hypoxia tolerance via TUC (time of useful consciousness) and to become aware of hypoxic symptoms. Because TUC depends on subjective symptoms and lacks strict objectivity, pulse oximetry monitoring has become useful in the aviation environment. In this study, we monitored arterial oxygen saturation (SaO2) by pulse oximetry in the ROKAF subjects (n=33) experiencing hypoxia at the simulated altitude of 25,000 ft. The duration from mask-off to mask-on (TUC), the duration from mask-off to the time of SaO2 of 90% (T90), the duration from 90% to 70% of SaO2(T70), and the SaO2 value at mask-on (bottom SaO2) were examined. The mean bottom SaO2 and TUC were 64.5% and 180 sec, respectively. The subjective hypoxic symptoms were facial flushing, thinking impairment, dyspnea, sweating, anxiety, and so on, in descending order. The majority of the subjects put on their mask before 70% of SaO2 was reached or before they felt any severe symptoms. In comparison with the data of JASDF (Yoneda, 2000), TUC, T90, and T70 were longer in JASDF, but bottom SaO2 and pulse increasing rate during hypoxia (PR/TUC) were higher in ROKAF. Also, TUC in the subjects of this study was much shorter than those of 10 years ago. These may be due to different training protocols, but not enough data exists to explain such difference. The need for the reconsideration of the hypoxic training from the various viewpoints is raised.

OBJECTIVE: To determine the safety and efficacy of immune ablation followed by autologous hematopoietic stem cell transplantation (HSCT) in refractory systemic lupus erythematosus (SLE). METHODS: Three patients who had been refractory to steroid and one or more immunosuppressive drug were included. Peripheral blood stem cells were mobilized with cyclophosphamide (CTX, 3 g/m(2)), followed by granulocyte-colony stimulating factor (5mug/kg/day). T lymphocytes were depleted from the graft by selection of CD34 positive cells. Conditioning regimens composed of high dose CTX (total dose 200 mg/kg) and anti-thymocyte globulin (total dose 90 mg/kg) in 2 patients and BEAM (BCNU 300 mg/m(2), etoposide 200 mg/m(2), cytarabine 200 mg/m(2), melphalan 200 mg/m(2)) in 1 patient. Stored stem cells were reinfused 48 hours after conditioning. RESULTS: Among 3 patients, first patient had lupus nephritis, second patient had overlap syndrome combined with rheumatoid arthritis (rhupus) and the last patient had severe thromobocytopenia and intractable polyserositis. No life threatening complications were observed during the treatment. All patients demonstrated rapid and marked improvement in organ function and quality of life just after HSCT. Previous massive proteinuria in first patient was decreased to less than 500 mg/day with 6 months follow up. Rhupus patient satisfied American college of rheumatology 70% response criteria with 3 months follow up. But third patient improved polyserositis dramatically 1 month after HSCT and relapsed at 9 weeks. CONCLUSION: In refractory SLE patients, HSCT can be performed safely with marked improvement and sustained withdrawal of all immunosuppressive medication. A further randomized trial is needed to confirm the efficacy and durability of remission.

OBJECTIVES: The purpose of this study was to investigate the prevalence of erectile dysfunction (ED) in a rural area of Korea and to examine the relationship between the prevalence and correlates of subjects. METHOD: This study was done as a part of the chronic disease survey of rural area by the Asan Foundation. Among 30 years or older population from Jung Eup, a rural area of Korea, 711 male subjects were sampled using a cluster probability sampling method. Trained interviewers visited and interviewed subjects aged 30 years or older with a structured interview. ED was categorized as 'none', 'mild', 'moderate', or 'severe' according to the ability to 'attain and/or maintain an erection satisfactory for sexual intercourse'. Response rate was 54.3% (N=386). RESULTS: The age weighted prevalence of ED was 27.2% (minimal 14.1%, moderate 7.6%, severe 5.5%). Prevalence and severity increased with age. Liver disease and underweight were significantly (p<0.05) associated with ED. Smoking seemed to be correlated with ED, but did not reach statistically significant level. CONCLUSION: ED was highly prevalent in the rural community of Korea. Medical, sociodemographic, and lifestyle variables associated with ED may alert physicians to patients at risk for ED and offer insight to its etiology.
