PURPOSE: To determine the extent to which magnetic resonance(MR) imaging findings can help differentiate between tuberculous arthritis (TA) and rheumatoid arthritis(RA). MATERIALS AND METHODS: This study involved sixteen patients with pathologically proven arthritis of the knee. In eight patients(mean age, 29.6 years; M:F=4:4) this was of the tuberculous variety, while eight (mean age, 47.5 years; M:F=2:6) suffered from the rheumatoid variety, which was monoarticular. For 14 patients, contrast enhancement studies were available. We retrospectively analyzed MR findings according to the demonstrated pattern of synovial thickening (regular and even, or irregular and nodular), bone erosion or abscess,bone marrow(BM) edema, the sites at which bursae were present, para-articular mass formation, and lymphadenopathy. RESULTS: In five of eight TA cases (62.5 %), irregular and nodular enhanced synovial thickening was present, while in six of eight RA cases (75%), thickening was regular and even. Bone erosions or subarticular abscesses were found in six TA cases (75%) and small erosions in three cases (37.5%) of RA. BM edema surrounding the erosion was found in four cases of TA (50%) and two of RA (25 %). In TA, edema was more extensive. In both TA and RA, all suprapatella bursae were distended while popliteal bursae were present in two cases of TA(25 %) and four of RA (50%). Para-articular masses with rim like enhancement were found in six cases of TA (75%) and in one case of RA (12.5 %). In particular, para-articular lymphadenopathy was seen in six cases of TA(75%), but not in RA. CONCLUSION: MR findings of irregular and nodular synovial thickening, extensive bone erosion, extensive BM edema, particular, para-articular abscess formation and ymphadenopathy, may help differentiate tuberculous arthritis of the knee from the rhumatoid variety.

2.Conversion of supraventricular arrhythmia to normal rhythm by propofol and remifentanil: three cases report.
Korean Journal of Anesthesiology 2014;66(3):244-247
We experienced conversion of supraventricular arrhythmia to normal sinus rhythm in three patients during general anesthesia using propofol and remifentanil. This may be related to direct inhibition of the cardiac conduction system or activation of the parasympathetic system. The literature review suggests that propofol and remifentanil have antiarrhythmic potential, reverting supraventricular arrhythmia during anesthesia.

BACKGROUND: Pseudo-Kaposi sarcoma mimicks Kaposi sarcoma, both clinically and histopathologically. These conditions are due to congenital (Stewart-Bluefarb syndrome) or acquired (Mali) vascular malformations. OBJECTIVES: The purposes of this study were aimed at evaluating the clinical and histopathological characteristics of pseudo-Kaposi sarcoma and finding differential diagnostic tools from Kaposi sarcoma. METHODS: Clinical information of 7 patients with pseudo-Kaposi sarcoma diagnosed in Asan Medical Center from 1989 to 1999 was obtained from the medical records and clinical follow-ups. We re-evaluated 10 biopsy specimens obtained from them and immunohistochemical studies for cutaneous lymphocyte antigen (CLA), CD34, vimentin, and factor VIII were performed with the standard streptavidin-biotin method using paraffin-embedded tissue specimens of 7 pseudo-Kaposi sarcomas and 3 Kaposi sarcomas. In addition, we examined whether human herpesvirus 8 (HHV8) was detected in 3 patients by polymerase chain reaction (PCR). RESULTS: Six male and one female patients were included. Mean age was 36.3 years. Three patients were classified into Mali type and the other four patients were into Stewart-Bludfarb type. Histopathological examinations revealed capillary proliferation in the upper dermis, perivascular infiltrate of inflammatory cells, extravasated red blood cells, and fibrosis of dermis. Anti-factor VIII and CD34 stained endothelial cells only. CLA was expressed in lymphocytic infiltrate in the epidermis and dermis of pseudo-Kaposi sarcoma, whereas it was negative in Kaposi sarcoma. PCR for HHV 8 showed negative results. CONCLUSIONS: Pseudo-Kaposi sarcoma is an uncommon entity with characteristic clinical and histopathological features. Differential diagnosis between Pseudo-Kaopsi sarcoma and Kaposi sarcoma is important. We suggest that detection of HHV 8 by PCR and imunohistochemical study for CLA may be effective tools in the differential diagnosis between them.

BACKGROUND: Lupus erythematosus profundus (LEP) is an unusual clinical variant of lupus erythematosus (LE). It is unclear which part LEP occupied in the disease spectrum of LE. OBJECTIVE: Clinical and histopathological studies were performed on 19 patients with LEP in order to further define the clinical patterns, know the various serological findings, and review the histopathological features. METHODS: A retrospective review was carried out of the clinical records and histopathological specimens of 19 patients with LEP. RESULTS: The most common clinical features were indurated nodules or plaques on the cheek. There was a 37% positivity in the ANA test. Histopathogically epidermal changes as well as subcutaneous involvements were common. There were no cases of newly developed SLE during the follow up period of 41 months. CONCLUSION: Most patients with LEP have a relatively benign disease course, although a few develop systemic abnormalities and have abnormal laboratory findings.

Dermatofibrosarcoma protuberans is a rare, slowly growing, locally invasive spindle-cell tumor characterized by a protuberant cutaneous mass with a pronounced tendency to recur and by a prominent storiform histopathologic pattern'-'. We present a case of dermatofibrosarcoma protuberans with myxoid area on the chest of a 57-year-old man. The histopathological study showed a dermal tumor of uniform spindle-shaped cells with storiform pattern. Immunohistochemically, the tumor was stained positively to anti-CD34 antibody and negatively to anti-factor XIIIa antibody.

Plexiform neurilemmoma is a relatively rare, benign peripheral nerve sheath tumor, whieh usually arises in either the dermis or subcutaneous tissue. These tumors may occur singly or as multiple lesions (plexiform neurilemmomatosis), We report an unusual case of plexiform neurilemmomatosis associated with cafe au lait spots reminiscent of neurofibromatosis clinically and another case of plexiform neurilemmoma on the finger. A Biopsy revealed the characteristic palisaded arrangement of spindle cells within well circumscribed elongated nodules, The skin lesions were completely excised without recurrence thereafter.

OBJECTIVE: To evaluate the maternal and fetal outcomes after transvaginal selective fetal reduction(SFR) in multifetal pregnancy. MATERIALS AND METHODS: Transvaginal SFR using fetal intracardiac puncture with KCl injection and aspiration of amniotic fluid was performed in 58 multifetal pregnancies achieved after assisted reproductive technology(ART). After transvaginal SFR, 55 twin and 3 singleton pregnancies were evaluated and analyzed retrospectively with the medical records of mothers and babies. RESULTS: Of 58 cases, abortion within 4 weeks after SFR occurred in 1 case(1.7%). Miscarriage of all fetuses occurred in 8 cases(13.8%) from 4 weeks after SFR until 24 weeks of gestation. Perinatal death occurred in 8 newborns from 5 mothers due to extreme prematurity in 7 cases and anencephaly in 1 case. Take-home baby rate, that is, discharge with at least 1 healthy baby, was 77.6%(45/58). CONCLUSION: Transvaginal SFR is an acceptable and effective management option in the cases of excessive multifetal pregnancy after infertility treatment. The ultimate successful outcomes of reduced multifetal pregnancy may be enhanced by more extensive experience with SFR.

BACKGROUNDS/AIMS: Although laparoscopic cholecystectomy is a common and widely accepted technique, the use of prophylactic antibiotics in elective laparoscopic cholecystectomy still remains controversial. The aim of this study is to determine whether prophylactic antibiotics could prevent surgical site infection after elective laparoscopic cholecystectomy and to identify any risk factors for surgical site infection. METHODS: This study included 471 patients undergoing laparoscopic cholecystectomy between January 2009 and May 2012. Period 1 patients (279) received second generation cephalosporin 1 g intravenously after induction of anesthesia, and Period 2 patients (192) were not given prophylactic antibiotics. The characteristics and surgical site infections of the patients were compared and analyzed. RESULTS: The overall rate of surgical site infection was 1.69% for the total of 471 patients. The incidence of surgical site infection was similar for the two Periods: 5 of 279 patients (1.79%) in Period 1, 3 of 192 patients (1.56%) in Period 2 (p=0.973). All of the patients with surgical site infections were well treated under conservative treatments without any sequelae. The preoperative albumin level (p=0.023) contributed to surgical site infection. CONCLUSIONS: Prophylactic antibiotics are not necessary for elective laparoscopic cholecystectomy but patients in poor nutritional state with low albumin level should consider prophylactic antibiotics.

It is well recognized that radiation can be carcinogenic for a wide variety of tumors, especially, in breast, thyroid, and bone marrow which appear to be radiosensitive. The criteria for establishing the dignosis of radiation- induced malignancy are the knowledge of prior irradiation and the appearance of a malignancy in the irradiated area. We report a case of carcinoma of the thyroid and esophagus following prior neck irradiation for thyroid mass.

Craniosynostosis is a congenital anomaly characterized by premature closure of cranial sutures. Surgical intervention should be performed during infancy. However, surgical correction of craniosynostosis remains bone defect and secondary angle occasionally. Currently, publications investigating solutions to bone defect and secondary angle created by cranioplasty are getting much interest. We have used BoneSource(R) which is relatively safe as an implantable substance for providing solutions for this problem. From June 2002 to January 2004, five children with craniosynostosis underwent frontocalvarial contouring using BoneSource(R) and concurrent cranial vault remodeling. The patient ages ranged from 8.0 months to 4.9 years(mean, 2.5 years). The quantity of BoneSource(R) implanted ranged from 10 to 25g, with a mean of 13g. This paper presents the first series of children treated with BoneSource(R) for frontocalvarial contouring in the surgical correction of craniosynostosis. No patients experienced any complications. Our results shows excellent retention of contour without causing asymmetry or irregularity. No visible evidence of interference with craniofacial growth were observed. Through our experiences, BoneSource(R) is found to be very useful for frontocalvarial contouring in children undergoing correction of craniosynostosis.
