PURPOSE: In young male patients who suffered several kinds of trauma with subsequent suspicious reflex sympathetic dystrophy syndrome, we performed three-phasic bone scan in order to investigate its usefulness. MATERIALS AND METHODS: Patients with narrow range of age (21-25. mean 22.8+/-1.3, all male) were included with suspicious reflex sympathetic dystrophy syndrome of 12 feet and 5 hands. Only one was bilateral feet case and 16 were ipsilateral (Rt:13, Lt:3). The etiologic traumas were 4 fractures, 4 sprains, 3 blunt trauma, 2 cellulitis, 1 tendon tear, 1 crush injury, 1 overexercise, and 1 unknown. Radiologically 3 showed osteoporotic changes. Three-phasic bone scans were performed 21.2+/-7.3wks after trauma. RESULTS: According to symptom complex, confirmatory reflex sympathetic dystrophy syndrome 4 cases and suspicious 13 were analyzed. All confirmatory cases (100%) showed increased uptake at delay phase with periarticular accentuation. Of confirmatory 4 cases, 2 showed increased uptake in all three phases (perfusion: P, blood pool: B, and delay: D), and other 2 revealed decreased P but, both increased B and D. Of suspicious 13 cases, 9(69.2%) had increased D (4 periarticular and 5 focal), 2 decreased D, and 2 symmetric D. In 12 foot cases, so-called weight bearing patterns - increased contralateral sole at P and B - were revealed in 7(58.3%). CONCLUSION: Diffuse periarticular increased uptake at delay phase of three-phasic bone scan was a compatible finding to reflex sympathetic dystrophy syndrome in young male patients whose symptom complex strongly designated post traumatic reflex sympathetic dystrophy syndrome.

Evaluation of a fever of unknown origin (FUO) is complex. Recently, PET scanning has been approved for screening in FUO evaluation. We treated three cases of FUO associated with increased FDG uptake in the bone marrow of the femur and tibia on the fusion PET/CT; all three had the same pattern of uptake. Bone marrow biopsies revealed mature lymphocyte and histiocyte infiltration and myxoid changes in one case, and cortical bone involvement in another case. The cases were all young females who had fever with neutropenia and relative lymphocytosis that lasted for several weeks and then remitted spontaneously. Even though the results of the studies were not diagnostic, the unique uptake pattern on PET/CT and the histology might be related to the cause of the illness and should be studied further to assess the association with classic FUO.

Splenic metastasis from solid cancer is a rare clinical event. Especially splenic metastasis from the lung is very rare. Most spleen metastases are found at autopsy and are part of a widely spread disease. Solitary splenic metastasis in the abscence of other metastases is extremely rare. The authors report the case of a 54-year-old man in whom the only discover distant metastasis from lung cancer was a splenic mass. The splenic lesion was detected after the resection of the primary lung lesion. The time from diagnosis to the development of splenic metastasis was 25 months. The rarity of a solitary spleen metastasis from lung cancer and the treatment modalities are discussed. When solitary spleen metastasis is suspected in a clinical setting, aggressive treatment is indicated, a splenectomy followed by combined modality treatment to prevent the spread and aggravation of the disease.

PURPOSE: This study was performed to evaluate MR signal intensity(SI) of calcification and to assess the capability of MRI in detection of various intracranial calcifications. MATERIALS AND METHODS: The MR findings and ROI value of experimental model of calcium carbonate suspension according to each concentration (20, 35, 50%) and diameter (1-10 mm) and hydroxyapatite suspension according to each concentration (10, 20, 30, 40, 50%) were analyzed. A specimen of calcification in cranio-pharyngioma was analyzed for its composition by XRD(X-ray diffractometer) and ICP(inductively coupled plasma) methods. MRI of 34 patients with intracranial calcifications were retrospectively analyzed for signal intensity of the calcification and its capability to detect calcifications according to size, location, and contrast with adjacent lesion. RESULTS: The calcium carbonate phantom with larger diameter and low concentration showed lower signal intensity on T2 than TlWl. Hydroxyapatite phantom showed high signal intensity in 10-30% concentration and low signal intensity in 40-50% concentration on T1 weighted image. The 5 cases of 34 intracranial calcifications showed high signal intensity on T1 weighted image. The capability of MRI in the detection of intracranial calcifications decreased in the circumstances such as small size(<2.5mm) and intraventricular location. Although the size of calcification was small, the detection was easy in the good contrast with adjacent lesion. However, the detection of the small sized calcification was easy if the contrast with adjacent lesion was good. CONCLUSION: lntracranial calcification shows generally low signal intensity on T1 and T2 weighted image with the exception of occasional high SI on TlWl. Detection of intracranial calcification in MRI is affected by its composition, size, location, and contrast with adjcent lesion.

PURPOSE: Male sexual desire and erection are directly or indirectly affected by hormone and neuroendocrine response. We investigate the changes of the serum dopamine and testosterone level by visual erotic stimulation-induced sexual excitement. MATERIALS AND METHODS: The age of volunteers was ranged from 25 to 65 years, with an average of 45.5years. Serum were collected at rest and after visual erotic stimulation. Sexual excitement induced by erotic film for 30 minutes and erectile status was monitored by Rigiscan. The response of visual erotic stimulation were divided into three groups according to degree of sexual excitement. i.e. no response (Group I), mild excitement(Group II), excitement (Group III). RESULTS: Although some changes were observed in serum dopamine and testosterone level of all 32 patients after visual erotic stimulation, it did not showed statistically signigicant change (p=0.450, p=0.058). According to excitement response, group I and II were not showed statistically significant change in both dopamine and testosterone. Only dopamine of the group III was showed statistically change (dopamine: p=0.041, testosteron: p=0.257) CONCLUSIONS: In this study, serum testosterone level is not showed significant change irrespective of the degree of sexual excitement induced by visual erotic stimulation. However, serum dopamine was changed with statistically significance only in sexual excitement group.

Malignant tumor have hypoxic cell fraction, which makes radio-resistant and hypoxia in tumor is a result from the blood flow decrease caused by increase in blood flow resistance. Blood viscosity increase is major factor of increased blood flow resistance and it could be attributed to the decrease in blood deformability index. For the evaluation of the change of blood viscosity and blood deformability in oral squamous cell carcinoma, we perform the test of the change of those factors between the normal control group and oral squamous cell carcinoma cell patient group. Relative viscosity measured against distilled water was 5.25+/-0.14 for normal control group, and 5.78+/-0.26 for the SCC patient group and there was statistical significance between the groups. However, there was no significant difference between the groups in blood viscosity between the groups by tumor size (T1+T2 vs T3+T4). Also, there was no significant difference between the normal control group and SCC patient group in blood deformability index and between the groups by tumor size (T1+T2 vs T3+T4). Increase in blood viscosity was confirmed with this study and it can be postulated that modification blood viscosity might contribute to decrease of hypoxia fraction in oral squamous cell carcinoma, thus improve the effect of radiotherapy and it can be assumed that the main factor of blood viscosity increase is not decrease of blood deformability in oral squamous cell carcinoma.

Acellular pertussis vaccine has been used widely in Korea since 1984. However, because many of the former generations were not inoculated with pertussis vaccine, they may infect infants with pertussis. With this background, we investigated the prevalence of pertussis antibodies in all age groups. Enzyme-linked immunosorbent assay (ELISA) to assess IgG antibodies to pertussis toxin (PT) and filamentous hemagglutinin (FHA) and bacterial agglutination (BA) to assess antibodies to agglutinogen were compared on 842 serum samples which were donated from 11 hospitals in Seoul area. In comparison with age groups under 20 years, antibodies of adults against PT and FHA were maintained. But antibodies against agglutinogen showed no pattem in all age groups. Antibodies to PT were correlated with antibodies to FHA. There was no significant difference in antibody levels between male and female (p<0.05).

Suprarenal IVC obstruction occurs rarely but has various causes. Because this obstruction proceed chronically and usually has collateral circulation, if there is no IVC or hepatic vein obstruction symptom such as Budd-Chiari syndrome, operation is usually needless. However, although symptom is not combined, if malignancy can not be ruled out and there is no proper and radiologically visible collateral, mass resection with IVC wall and bypass graft should be done. 58 year-old female patient visit the hospital for IVC mass that is occasionally discovered by routine abdominal ultrasonography examination. After abdominal CT scanning and IVC venography, IVC obstructive mass between renal vein and hepatic vein was found. Patient didn't show any abnormality in hematological examination such as coagulation and platelet counts. There was no IVC obstruction symptom such as lower limb swelling. Inferior hepatic vein was abnormally dilated and this was regarded as collateral vessel for IVC obstruction. Radiologically, primary leiomyosarcoma was not ruled out and so operation was decided. Suprarenal IVC was dissected and mass was exposed. And with the use of femoral vein and right atrium, temporally veno-veno bypass was performed. Mass including IVC wall was excised and upper end of divided IVC was sutured. Lower end of divided IVC was anastomosed with 16 mm Dacron graft and graft was anastomosed with right atrium by end-to-end methods (Cavoatrial shunt). Postoperative pathologic examination revealed the mass to be organized thrombi. After 2 weeks later, follow-up IVC venography was performed and good patency was found from IVC to right atrium through artificial bypass graft and patient was discharged without complications.
