PURPOSE: To identify the four layers based on intranodular vascular nature visible in multiphase incremental bolus dynamic CT and to determine any differential points according to various factors of liver abscess with this vascular nature or not. MATERIALS AND METHODS: We categonized 29 cases of confirmed liver abscess into three different groups according to presence of four layers visible in early phase(arterial phase) of CT. Three groups were compared in regard to the results of antiamebic antibody test and bacteriologic study and presense of cholangitic abscess and internal septation. RESULTS: We could separate four layers, innermost hypodense central cavitary lesion, hyperdense granular tissue, hypodense abscess wall and outermost hyperdense compensatory hypervascular zone in 18 cases(62%), only two layers, cavity and wall in six cases(21%), and characteristically we could find three layers without innermost cavitary lesion in five cases(17%). But we couldn't find significant correlations between various clinical factors of liver abscess and our vascular groups. CONCLUSION: Our method of CT could represent four layers based on vascularity in 62% of cases. And also could find the unusual inflammatory mass containing three layer which must be differentiated from other malignant solid mass. But we couldn't find differential point between various clinical factor of liver abscess and imaging diagnosis. We think that with the improvement of hardware such as spiral CT, identification of four layers will be earier and will be very helpful in early detection and proper treatment planning of liver abscess.

Extravasation of toxic chemotherapeutic 'agents cause severe skin ulceration and necrosis which often need secondary surgical intervention. Still, there were not established antidote agent in case of extravasation with mitomycin-c. Dimethyl sulfoxide is known as an effective chemical scavenger of toxic hydroxyl free radical and sodium thiosulfate also was demonstrated significant protector from mitomycin-c induced ulceration by a few experimental studies. Author investigated necrotic area of mitomycin-c injected site and compare to the effectiveness of topical treatment with dimethyl sulfoxide and intradermal injection of sodium thiosulfate according to starting times, forty five mice were divided into 3 groups. Control group(n=5) had no treatment after subcutaneous injection of mitomycin-c. Experimental group I and 11 were 20 mice treated dimethyl sulfoxide and sodium.

We report 2 cases of midface defect reconstructed with latissimus dorsi myocutaneous free flap. In these cases, the main points to cover the defects were as follows: 1. For the contour of zygoma and maxilla, it was well preserved without bone graft which was not used for second stage reconstruction. In first case, for application of artificial eyes and in second case, for operation after full development. 2. For the drainage of paranasal sinuses, we made the nostril with skin graft, and it was well preserved without any complications during follow up. 3. It was sufficient to cover the defect with latissimus dorsi muscle well designed before surgery and thick enough to fill the defect. 4. In second case, the remained defect of palate and maxilla was not covered for the appropriate reconstructions after full development. In conclusions, we experienced two cases of midface defect reconstructed with latissimus dorsi myocutaneous free flap without any complication and with good results.

Augumentation rhinoplasty using autogenous cranial bone graft (outer table) can be used more successfully than other methods. In patients with congenital or posttraumatic severe saddle nose deformity and lateral deviation, cranial bone graft is an excellent method of augumentation. The advantages of cranial bone graft compared with traditional method of bone graft are summarized as follows; 1. Easy to reach donor site 2. Abundance of material 3. Little pain and functional disability 4. Shorter hospitalization period 5. Inconspicuous donor scar 6. No secondary deformity of donor site 7.Appropriate curvature can be obtained by proper selection of donor site. With the above advantages, we conclude that augumentation rhinoplasty using split cranial bone graft is a good method in correction of congenital or posttraumatic deformity of nose.

Hemorrhagic cystitis is potentially life-threatening sequellae of chemotherapy using oxazaphosphorine alkylating agents (cyclophosphamide and ifosfamide). Mesna contains a sulfhydryl group that is believed to bind acrolein within the urinary collecting system and reduce the hemorrhagic cystitis without affecting the chemotherapeutic potential. To date, about thirty cases of hypersensitivity or allergic reactions of the delayed and urticarial type associated with mesna have been reported. We reported two patients with systemic lupus erythematosus who developed facial rash and flushing associated with mesna which imitate malar rash.

BACKGROUND:Acute vestibular neuronitis is the disease of which the etiology and pathophysiology are largely unknown . But the viral infection and ischemia of the labyrinth and the vestibular nerve are considered as general etiology. This study was performed to support the viral infection rather than the ischemic theory. MATERIALS & METHODS:We studied seventy years old female patient who showed painful vesicles on left auricle and vertigo with spontaneous nystagmus to the right side. We performed physical examination, serologic test, ENG test, pure tone audiogram, brain magnetic resonance imaging and polymerase chain reaction. RESULTS:We found small vesicles and vascular injection in left EAC, herpes zoster IgG positive, spontaneous right beating in electronystagmograpy, 54% left canal paresis in Caloric test , decreasing left side Tc in velocity step rotatory test, decresed gain, deviation to left in symmetry and phase lead in sinusoidal harmonic acceleration test, normal range hearing in pure tone audiogram, microangiopathy on cortex in brain MRI and negative PCR. CONCLUSION:This case supports viral infection etiology rather than ischemia in vestibular neuritis. But more studies to find the etiology of vestibular neuronitis are required.
