The authors presented a case of gastroschisis with a pedunculated gallbladder embedded in hepatic tissue. The patient was born after fullterm gestation. Due to extensive abdominal wall defect, she succumbed 3 days after birth. There was a pedunculated mass measuring 2.5x1.5x1.5 cm between the liver and distended stomach without any attachment to the liver. The pedicle of the mass was connected to the common bile duct. Cut surface revealed that the mass was an accessory hepatic lobe encircling the gallbladder. The histologic feature of both accessory liver and gallbladder was markedly altered probably due to vascular obstruction. We could find only a single similar case in literlature. That case was associated with Beckwith syndrome and ours was associated with large atrial spetal defect, large patent ductus arteriosus, accessory spleen as well as gastroschisis. The common feature of abdominal wall defect might be a predisposing factor.

PURPOSE: Epstein-Barr virus(EBV) exists in the human population in two genetic forms, usually referred to as type 1 and type 2 which have been defined on the basis of sequence divergence in the EBNA-2 and EBNA-3 family genes. In this study, we were intended to investigate whether the subtypes of EBV in malignant lymphoma in Korea were associated with specific disease entities and geographical distribution. MATERIALS AND METHODS: Biopsy samples obtained from 18 Korean patients with malignant lymphoma including Hodgkin's disease(3 cases), B cell lymphoma(1 case), and NK/T cell lymphoma(14 cases) were analyzed to determine the subtype of EBV infected therein. DNA was extracted from formalin-fixed, paraffin-embeded tissues by ordinary method and specific viral sequences were sought using the polymerase chain reaction(PCR) and Southern blot hybridization assay. Oligonucleotide primers used for examination of EBV strain type were derived from the EBNA-3B and EBNA-3C coding regions. As a control, four cases of reactive hyperplasia were analyzed. RESULTS: The two of four reactive hyperplasia cases were associated with type 1 and the rest of two cases with both types. Among the 18 cases with malignant lymphoma, thirteen cases(72%) had type 1, one(6%) had type 2, and four(22%) had dual infections with both types. In case of NK/T cell lymphoma(14 cases) occupying 78% of 18 biopsy samples, 86%(12 cases) were associated with type 1, 7%(1 case) with type 2, and 7%(1 case) with both types. In case of Hodgkin's disease, all of three cases had both types. B cell lymphoma taking only one case of twenty two cases was determined as type 1. CONCLUSION: These observations indicated that type 1 EBV was predominant in Korean patients with malignant lymphoma, especially NK/T cell lymphoma and showed high frequency of dual viral infections(22%) in Hodgkin's disease as well as in reactive hyperplasia.

PURPOSE: To analyze factors influencing clinical results after microfracture surgery in patients with osteoarthritic knee. MATERIALS AND METHODS: After microfracture surgery, in sixty-six patients with sixty-eight knees having full thickness chondral defect by arthroscopic evaluation, clinical results were evaluated with Baumgartner's nine-point scale during the follow-up of 1 year 4 months (range, 1-2 years 5 months). Results were analyzed according to age, the degree of preoperative varus and the existence of flexion contracture. RESULTS: Sixty-three knees showed excellent or good results at clinical evaluation. According to age, a significant difference was observed about 65 years old (p<0.05). The patients without flexion contracture and with less varus change had better clinical results, as did patients whose medial deviation of mechanical axis was less than 75% (p<0.05). CONCLUSION: Better clinical results, after microfracture surgery, were obtained in patients who were under the age of 65, with less than 75% of medial deviation of the mechanical axis on standing AP radiogram and no flexion contracture.

Among cystic tumors arising in the pancreas, microcystic adenoma is relatively uncommon; it is usually benign, and is comprised of cysts that vary in size from microscopic to 2cm in diameter. It has recently been reported to be associated with other pancreatic tumors with malignant potential; in particular, microcystic adenoma with coexistent islet cell tumor has been reported in von Hippel-Lindau disease. We report a case of microcystic adenoma of the pancreas associated with coexistent surgically-proven islet cell tumor. On spiral CT, the islet cell tumor was seen as a highly enhanced inhomogeneous solid mass in the pancreatic head, and microcystic adenoma as numerous small cysts throughout the pancreas.

OBJECTIVE: Gamma knife radiosurgery (GKRS) is the least invasive surgical option for patients with trigeminal neuralgia (TN). However, the indications and long term outcomes of GKRS are still controversial. Additionally, a series with uniform long-term follow-up data for all patients has been lacking. In the present study, the authors analyzed long-term outcomes in a series of patients with TN who underwent a single GKRS treatment followed by a minimum follow-up of 60 months. METHODS: From 1994 to 2009, 40 consecutive patients with typical, intractable TN received GKRS. Among these, 22 patients were followed for >60 months. The mean maximum radiation dose was 77.1 Gy (65.2-83.6 Gy), and the 4 mm collimator was used to target the radiation to the root entry zone. RESULTS: The mean age was 61.5 years (25-84 years). The mean follow-up period was 92.2 months (60-144 months). According to the pain intensity scale in the last follow-up, 6 cases were grades I-II (pain-free with or without medication; 27.3%) and 7 cases were grade IV-V (<50% pain relief with medication or no pain relief; 31.8%). There was 1 case (facial dysesthesia) with post-operative complications (4.54%). CONCLUSION: The long-term results of GKRS for TN are not as satisfactory as those of microvascular decompression and other conventional modalities, but GKRS is a safe, effective and minimally invasive technique which might be considered a first-line therapy for a limited group of patients for whom a more invasive kind of treatment is unsuitable.

BACKGROUND: Several workers have found that Malassezia are capable of suppressing cytokine release and downregulating the phagocytic function of monocytes. But lipid-depleted Malassezia furfur (M. furfur) extracts have also been shown to induce increased production of TNF-alpha, IL-6 and IL-1beta in monocytes. We thought that the detergents in shampoos or soaps could change the composition of the lipid in the M. furfur cell wall. OBJECTIVE: We studied whether detergents affect the morphology of M. furfur and if the inflammatory cytokine profiles change in the monocytes treated with detergent-treated M. furfur. METHODS: Commonly used detergents such as sodium lauryl sulfate, ammonium lauryl sulfate and tween-80 were respectively added to the modified Leeming-Notman's media. M. furfur was cultivated in each media (detergent-added or untreated). Thereafter, the surface morphology of the yeast was evaluated by scanning and transmission electron microscopy. The cytokine profiles of monocytes, which were treated by M. furfur with or without detergents, were also evaluated. RESULTS: The detergent- treated M. furfur were similar to the lipid-extracted form of M. furfur on the electron microscopic study, with a recessed, withered surface and with thinner and rather electron transparent cell walls than the detergent-untreated M. furfur. The levels of TNF-alpha were higher in monocytes treated with detergent-treated Malassezia than that in the monocytes treated with the detergent-untreated Malassezia (p <0.05). CONCLUSION: According to the findings in this study, it could be inferred that the detergents in shampoos or soaps affect the lipid layers of the Malassezia cell wall and these lipid-extracted Malassezia induce or aggravate some inflammatory conditions. But to correlate the relationship between detergents and Malassezia-associated diseases, in vivo experiments that will focus on short-term contact with detergents in real life conditions should be done.

Darier's disease is an uncommon genodermatosis, characterized by the symmetric eruption of keratotic papules, focal loss of epithelial adhesion and abnormal keratinization. A unilateral, or localized variant has been identified as a mosaic form, involving linear or 'zosteriform' epidermal lesions with clinical and histological features of Darier's disease. Some suggest that unilateral lesions should be classified as acantholytic dyskeratotic epidermal nevi, rather than localized Darier disease. A 17-year-old male presented with unilateral zosteriform distribution of brownish hyperkeratotic papules with ipsilateral v-notching of the thumb nail. A biopsy specimen revealed acantholysis, suprabasal cleft and multiple dyskeratotic cells. We report a case of unilateral Darier's disease which further supports unilateral dermatologic manifestation as a variant of Darier's disease.
