Infantile hemangioendothelioma of the liver is a common vascular tumor in infancy. The tumor is usually multinodular or diffuse and classified into two types. We present a case of infantile hemangioendothelioma of the liver, which predominantly consists of type 2. A 4-month-old female was admitted for an evaulation of an abdominal distension. A CT scan of the liver showed a multinodular mass. The right lobectomy was done. Grossly, the mass consisted of round nodules ranging from 2cm to 5cm in diameter. Microscopically, the tumor revealed proliferation of small vascular channels lined by endothelial cells. Bizarre cells and mitotic cells were frequently noted. Vesicular nuclei and multilayering of the endothelial cells were also noted.

One of the complication during or after subclavian vein cannulation is intravascular catheter or wire embolization. Although some studies have reported safety of retaining foreign body embolization, and even death. The intravascular foreign body can be removed surgically or non-surgically. With improvement in instrument technology and technique, percutaneous retrieval of intravascular foreign bodies has become a relatively common procedure. Commonly used methods to remove intravascular foreign bodies are loop snare and basket technique. Sometimes biopy forcep can be used. We have experienced 2 cases of non-surgical removal of intravascular foreign bodies. One of the foreign bodies was 7cm wire fragment in right atrium(RA), the other was a 50cm guide wire. We used the standard loop snare technique for removal of 7cm wire fragment in RA and stone removal basket and 3.0mm ACS PTCA balloon to remove the 50cm short guide wire.

OBJECTIVE: Angiogenesis is a critical factor in the progression of solid tumors. The mechanisms responsible for angiogenesis in cervical neoplasia, however, are not well defined. Our study was aimed to determine the expression of VEGF(Vascular Endothelial Growth Factor), its receptor(KDR), and TGF-beta1(Transforming Growth Factor-beta1) in cervical neoplasia, to determine the role of these angiogenic factors in preinvasive(dysplastic) process and the progression of cervical cancer and to investigate the progression of angiogenesis in the transition from normal cervix to invasive squamous cell carcinoma of the uterine cervix. METHODS: The cervical lesions of 76 patients were punch biopsied and paraffin embedded. Among these, 5 were normal cervix, 36 were cervical intraepithelial lesion I-III, and the other 35 were invasive squamous cell carcinomas. The tissues were immunostained with antiVEGF, antiKDR, and antiTGF-beta1 polyclonal antibody. RESULTS: The expression of VEGF, KDR, and TGF-beta1 in CIN III was stronger than those of CIN I(p<0.01). Their expression were not significantly different among the each staged cervical cancers(p>0.01). CONCLUSIONS: These observations suggest that VEGF, KDR, and TGF-beta1 are important angiogenic factors in cervical neoplasia, especially in an early event to neoplastic transformation of cervical tissues, but these angiogenic factors are not associated with the progression of cervical cancer.

Primary intracranial choriocarcinoma is a extremely rare neoplasm since the case was reported by Askanasy, in 1906, there have been 35 reported, even if germinal neoplasms containing chorocarcinoma-like tissue are added. But pure choriocarcinoma was rarely reported. The purpose of this paper is to report a case of 18-year-old boy with tumor in subependymal region around left frontal horn, which was present with high level of serum beta chain of chorionic gonadotropin(B-HCG) and was verified as germine choriocarcinoma by biopay.

PURPOSE: We evaluated the MR and CT findings of the masticator space lesions in order to identify the differences among the malignant and benign tumors and infectious conditions. MATERIALS AND METHODS: MR and CT findings in 46 cases with proven masticator space lesions were reviewed retrospectively. We analysed the involvement of masticator muscles, adjacent spaces, orbit and intracrahium, homogeneity, necrosis, cystic changes, growth patterns, calcifications, enhancement patterns, MR signal intensity, and CT attenuation. RESULTS: Among the 29 cases of malignant tumors, seven cases were mandibular tumors including four chondrosarcomas, and 22 cases were extramandibular tumors. Malignant tumors of mandibular origin showed large masses with severe bone destruction and epicenter of mandible. Extramandiblular malignant tumors showed the epicenter out of the mandible and less severe bone destruction than mandibular tumors: Among the nine benign tumors, four cases were ameloblastomas which showed the well-defined masses and the expansion of the mandible, and four cases were extramandibular tumors which showed well-marginated extramandibular masses with no bone destruction. Among the eight infectious conditions, five cases were mandibular osteomyelitis with or without abscess formations, and the other three cases were infections from adjacent soft tissue or limited to the soft tissue. CONCLUSION: By careful observations of growth patterns, involvement of the masticator and adjacent spaces, bone changes, and epicenter of the lesions, one can discriminate a mandibular lesion from an extramandibular lesion. With this approach, it is thought to be easier to suggest a dignosis among a wide spectrum of masticator lesions.

PURPOSE: This study was performed to determine the usefulness of blood culture in the management of febrile immunocompetent patients presenting emergency department. METHODS: We prospectively analysed the medical characteristic and the result of blood culture of febrile immunocompetent patients who presented to Chonnam National University Hospital emergency center form April 2005 to October 2005. RESULTS: The study included 182 patients. The characteristic associated with the positive result of blood culture on multivariate analysis was the low initial level of albumin. Of the 182 culture, only 26 were true positive(14.3%). Of them, the result of blood culture influenced management in five patients (2.7%). CONCLUSION: The blood cultures has usually been ordered in febrile immunocompetent patients at emergency department has the limited usefulness. The emergency physician who initially treats them has to consider this limitation of it.

BACKGROUND: This study was performed to accurately discover the correlation between the epidural depth and physical measurements. METHODS: We measured the L2-3, L3-4 epidural depth pre-marked on the needle shaft only when the block was successful. Correction of the depth was made by the angulation of the needle from the perpendicular line (with regard to both the x- and y-axis) to the skin. Height and weight from the medical record was noted and neck, waist, and hip circumferences of each subject was measured. Physical parameters such as waist/neck (waist circumference-to-neck circumference ratio), waist/height (waist circumference-to-height ratio), waist/hip (waist circumference-to-hip circumference ratio), weight/neck (weight- to-neck circumference ratio), weight/height (weight-to-height ratio) and body mass index (BMI) were calculated. Peason's correlation and a regression test between the epidural depth and the physical mea surements were performed. RESULTS: Significant correlation with epidural depth was found in weight, waist, hip, neck, BMI, waist/height, waist/hip, weight/neck, and weight/height. With the regression test, we found weight to be the most important for predicting epidural depth (R square = 0.330, P < 0.05). CONCLUSIONS: Weight has the highest predictive value for lumbar epidural depth.
