Transcatheter hepatic arterial embolization (THAE) is one of the treatment modalities that can be applied to hepatocellular carcinomas (HCC) and metastatic tumors of the liver. Complications such as cholecystitis and gallbladder necrosis, are common with THAE, but liver and peripheral bile duct necrosis are rare, and intrahepatic stones with main bile duct necrosis have never been reported. To prevent intrahepatic spread during operative manupulation and to decrease the vascularity and size of the tumor, we performed a THAE on a huge-sized HCC five times before performing the hepatectomy. We succesfully undertook a right lobectomy after the THAE with lipiodol, gelform, and adriamycin. However, severe bile duct stricture and intrahepatic stones were confirmed during the operation.

Aneurysm of the internal carotid artery is a rare disease and is known to be associated with congenital arterial anomalies such as neurofibromatosis type I (NF-I). NF-I is an autosomal dominant neurocutaneous disorder characterized by a variety of manifestations that involve the central and peripheral nervous systems, skin, vascular system, and skeleton. In particular, the involvement of vascular abnormalities in NF-I is well known. Any vessel may be affected by this condition, although the renal artery is most frequently involved. The vascular abnormality can be occlusive or an aneurysmal degenerative change. Therefore, symptomatic presentations might assume an indolent pathophysiologic course such as hypertension, or manifest as a catastrophic event such as arterial rupture that could result in sudden death. We report a rare autopsy case of an aneurysmal rupture of the internal carotid artery in a woman with suspected NF-I, who collapsed in her home.

BACKGROUND: Suction auto epidermal graft for the treatment of stable vitiligo has become popular clinically. In general, depigmented epidermis is removed by liquid nitrogen freezing for preparation of the recipient site. There have been some problems with the nitrogen freezing method, uneven repigmentation, appearance of Koebner's phenomenon on normal colored skin around the graft site, scar formation on recipients sites. In our view these resulted in unwanted damage to the dermis and epidermal and skin appendageal melanocytes of normal skin by freezing. OBJECTIVE: To introduce a method to remove the depigmented epidermis of recipient site with minimal unwanted damage to melanocytes and dermal tissue. METHODS: Using Ellman surgitron, irradiation equipment of 3.8MHz frequency the depigmented epidermis was removed with a blade electrode under rated electric power around 10 watts depending on the thickness of the epidermis. Operating mode was fully filtered current for minimal charring and destruction of tissue through pure micro-smooth cutting. RESULTS: In the case of removal of the epidermis with Ellman surgitron, oozing and inflammation decreased markedly compared with those applied with liquid nitrogen. And it was confirmed histopathologically that there was no significant unwanted destruction of healthy tissue. Moreover, the electrode of Ellman surgitron is designed to be apt to trace the margin of depigmented lesion. And Ellman surgitron features a continuously linear intensity setting for precise, predictable control to minimize tissue destruction and charring. So we were able to remove the epidermis of the shallow lesion looking like a pseudopod and of the thinnest part of the body like eyelid also. And we grafted normal epidermis successfully on the depigmented lesion. CONCLUSION: The removal of depigmented epidermis by radio-frequency gave satisfactory results in the suction auto epidermal graft by overcoming the defects shown as depigmented epidermis which were removed by liquid nitrogen freezing. And this method made patients comfortable because of less pain, a one day operation procedure and good results.

OBJECTIVES: Somatic symptoms after the exposure of psychological trauma frequently developed. However, the somatic symptoms are not covered under the diagnostic criteria of posttraumatic stress disorder(PTSD) in detail, although they are often associated with social and occupational functioning and patient-doctor relationships. The aim of this article is to highlight the potential mechanisms, the common manifestations, and the treatment of the somatic symptoms. METHODS: This article studied the somatic symptoms searched using academic search engines like PubMed, Scopus, Google Scholar, KoreaMed and KISS from the earliest available date of indexing to March 31, 2016. RESULTS: The mechanism of somatic symptoms after the exposure was described as psychological and physiological aspects. Psychological mechanism consisted of psychodynamic theory, cognitive behavioral theory, and others. Physiological mechanism involved changes in neuroendocrine and immune system, autonomic nervous system and central nervous system. Somatization associated with psychological trauma manifested various health conditions on head and neck, chest, abdominal, musculoskeletal, and dermatological and immune system. Few studies described the standardization of treatment for the somatic symptoms. CONCLUSIONS: Clinicians and disaster behavioral health providers should think of the accompanying somatic symptoms during intervention of psychological trauma and PTSD. Further studies are needed on the somatic symptoms seen in psychological trauma and PTSD.

BACKGROUND: The main function of melanocyte is known to protect the skin from hazardous sunlight. But, some investigators have claimed lately that melanocytes are also related to the immunologic role in the epidermis because these cells produce IL-1 activity and IL-1beta convertase activity, in vitro. OBJECTIVE: Our purposes were to investigate the effects of rIFN-gammaon the proliferation of melanocytes, melanin content, and the expression of HLA-DR antigen on melanocytes after a rIFN-gammaexposure. MEHTODS: The number of melanocytes, the melanin content, and the expression of HLA-DR antigen were evaluated on cultured human melanocytes according to a time sequence and various concentrations of rIFN-gamma. RESULTS: Antiproliferative activity on melanocytes was dependent on the exposure time and the concentration of rIFN-gamma. According to the exposure time and the concentration of rIFN-gamma, melanogenic acivity was inhibitd or stimulated. Normal melanocytes didn't express HLA-DR antigen, but when normal melanocytes were exposed to rIFN-gamma, the expression of HLA-DR antigen increased in a time-and concentration-dependent fashion. After the removal of rIFN - gammafrom the culture media, the expression of HLA-DR antigen on melanocytes also disappeared. CONCLUSION: In our study, melanocytes seem to be related to the immunologic role in the epidermis because these cells expressed HLA-DR antigen after rIFN-gammaexposure and we think that study could help to investigate between melanocytes and immunologic mechanisms in various inflammatory skin diseases.

PURPOSE: To determine the relation between clinical results and correction angle in proximal tibial osteotomy through the retrospective study. MATERIALS AND METHODS: Seventy-two valgus osteotomies of the tibia were performed in forty-nine patients from 1985 to 1992; average follow-up period was 7 year 11 months(range, 5 to 12 years). We classi- fied the patients into three groups according to the tibiofemoral angle measured at the last follow-up. Group I includes patients with less than valgus 6 degrees of tibiofemoral angle, Group II with from valgus 7 degrees to 9 degrees and Group III with more than valgus 10 degrees. RESULTS: The Insalls Hospital for Special Surgery knee score was gradually decreased in time as 95 at postoperative 2 years, 92 at 5 years and 82 at the last follow-up. The average preoperative tibiofemoral angle was varus 3.4 degrees and the average postoperative tibiofemoral angle was corrected as valgus 8.0 degrees, 7.9 degrees at two years, valgus 7.0 degrees at five years and valgus 5.4 degrees at the last follow-up. The group I, 40 cases(mean 9 year 7 month follow-up), showed postoperative valgus 6.4(3-15) degrees and val- gus 2.6 degrees at the last follow-up. Loss of correction was 3.8 degrees and knee score was 76 at the last fol- low-up. The group II, 21 cases(8 year 1 month), showed postoperative valgus 9.0(7-11) degrees and 7.6 degrees at the last follow-up. Loss of correction was 1.4 degrees and knee score was 83.5 at the last follow- up. The group III, 11 cases(7 year 7 month) showed postoperative valgus 11.4(10-15) degrees and 10.9 degrees at the last follow-up. Loss of correction was 0.5 degrees and knee score was 97 at the last follow-up. The group III showed better maintenance of postoperative correction angle and clinical results than the other gf OUpS. CONCLUSION: Deductively, it is essential to correct tibiofemoral angle more than 7, especially ranged from 10 to 15 degrees for the best long-term clinical results.

Posterior epidural migration of a sequestrated intervertebral lumbar disc is rare with only five cases ever reported in the literature so far. The objective of this paper is to report our experience of such a extremely rare case with a review the literature

SUMMARY OF LITERATURE REVIEW: Many authors haute described the association between lumbar disc degeneration and segmental instability but it has not been delineated in detail. OBJECTIVES: To compare the MRI assessment of disc degeneration with the conventional plain X-ray evaluation of the intervertebral disc, in order to study lumbar segmental instability. MATERIALS AND METHODS: In 75 patients with low back pain and/or sciatica, we analyzed disc space height, angular displacement, and horizontal displacement on plain radiographs of the lumbar spine. These parameters were compared with the grade of disc degeneration as evaluated by magnetic resonance Imaging. STUDY DESIGN: We analyzed the association between grade of disc degeneration as evaluated by magnetic resonance imaging assessment and segmental instability as evaluated by plain radiographs of the lumbar spine. RESULTS: Disc space height was decreased In proportion to the grade of disc degeneration. Angular displacement was increased according to the grade of disc degeneration, but significantly less with severe degeneration, accompanied by a tendency to stabilization of the motion segment. Horizontal displacement was not correlated with the grade of disc degeneration CONCLUSIONS: The incidence of lumbar segmental instability increased in proportion to the grade of disc degeneration but significantly decreased with severe disc degeneration.
