BACKGROUND: Early esophageal cancer has a good prognosis compared with advanced esophageal cancer, so early detection of the cancer is emphasized. Early esophageal cancer is considered as esophageal cancer located within the submucosal layer and without metastasis in the operative specimen. Despite this criterion, evidence has accumulated suggesting that submucosal tumors have a very different prognosis from intra-epithelial and intramucosal lesions. The purpose of this study is to define the characteristics of and the appropriate operative method for esophageal cancer. METHODS: Medical records of 19 patients who had received an esophagectomy and who had been diagnosed as having early esophageal cancer between 1981 and 1996 at this hospital were reviewed. RESULTS: There was 17 cases of submucosal lesions and 2 cases of mucosal lesions. 74% of the patients had alcohol or smoking history. When endoscopic findings were classified according to the endoscopic classification of JSED, there were 5 cases of type 0-I, 4 cases of type 0-III, 4 cases of type 1, and others. Type 0-I and 0-III were common. The accuracy of the endoscopic ultrasonographic finding was 39% compared with the postoperative pathologic finding. The mean duration of follow-up was 21 months, and there were 2 recurrences during follow-up. One recurred 13 months after the operation and the other 23 months after the operation. Both of them were submucosal lesions and received a transhiatal esophagectomy. CONCLUSIONS: Annual endoscopic examination with lugol staining may be needed for early detection of esophageal cancer. Submucosal lesions of early esophageal cancer should be managed with an esophagectomy and lymph node dissection. Also, expertness of the endoscopist is very important in deciding on an of operative method.

A 20-year-old woman was admitted because of intractable seizures, myoclonus, gait ataxia, and severe intellectual deterioration with age of onset at 16 years. She had no family history of neurological disease. A thorough laboratory investigation was unremarkable. Brain MRI showed generalized cerebral and cerebellar atrophy. Interictal EEG showed intermittent generalized polyspike and waves, maximum on the bilateral parieto-occipital areas, and MNSEP showed giant cortical SEP. Brain biopsy revealed intraneuronal accumulation of granular osmiophilic deposits (GROD), which is characteristic of electromicroscopic findings of neuronal ceroid lipofuscinosis (NCL). We report biopsy-proven adult NCL, which is one of the rare neurodegenerative diseases. (J Korean Neurol Assoc 19(1):45~48, 2001

We described a population-based study of the epidemiology of herpes zoster in military personnel of Korea. A total of 132 cases of herpes zoster were ascertained from May 2004 to April 2005. The most common site of involvement was thoracic area (55%). The annual incidence, based on 132 cases in about 80,000 person-years, was 165 per 100,000 person (95% CI, 138-196). It is noted that herpes zoster occurred frequently in otherwise healthy military personnel.

We report a case of Castleman`s disease of the hyaline-vascular type which was located in retroperitoneum. A 20-year-old girl was admitted because of a history of postprandial epigastric discomfort. Computed tomography of the abdomen demonstrated a solid 7 x 7 cm mass between the abdominal aorta and the left kidney in the retroperitoneum. At surgery, a solid 9 x 8 x 6 cm tumor was resected. Pathologic diagnosis was Castleman`s disease of the hyaline-vascular type.

Carcinoma of lung is classified by histologic cell type, this is based on predominant major cell population by tissue specimen. But in fact a range of 13% to 63% of lung cancer has been appeared to be heterogeneous cell type at the light microscopic level. After treatment of the mixed lung cancer and/or with time there are reports that cell type is changed. Because it is possible that the tumor were pleomorphic and that the antitumor therapy eliminated the more sensitive cell population and permitted the subsequent emergence of the more resistant cell population. The authors reported here, a case of 32 year old female patient with mixed lung cancer composed of three cell type, and this is the first case in Korea.

The tumorous type of endobronchial tuberculosis was reported to be 5 to 10% in the bronchoscopic examination. It was protruding mass that tuberculous mediastinal lymph node ruptured into the bronchial lumen. Generally histologic examination has been performed for purpose of differentiation, because the tumorous type of endobronchial tuberculosis simulate lung cancer in bronchoscopic finding. A case considering operation similar to bronchial adenoma in the bronchoscopic finding was confirmed to endobronchial tuberculosis by positive AFB and disapperance of mass after antituberculosis medication. Case history was presented and reviewed.

PURPOSE: Peanut allergy is a major cause of fatal food-induced anaphylaxis. Cooking methods can affect the allergic properties of peanut proteins. The aim of this study was to determine the allergenicity of peanut according to cooking methods. METHODS: Eight kinds of peanut were included in the study: raw peanut, boiled peanut, roasted peanut (10 min, 20 min and 30 min), peanut butter, fried peanut and vinegarish peanut. The proteins were extracted with PBS and analyzed using the SDS-PAGE IgE immunoblot assay with pooled sera from 8 patients with atopic dermatitis. These patients had peanut- specific IgE levels greater than 15 kU/L, which were measured by the CAP-FEIA. RESULTS: The SDS-PAGE IgE immunoblot assay revealed more intense protein bands of Ara h 2 in roasted peanut and peanut butter than in raw, boiled, fried and vinegarish peanut. The protein band of Ara h 1 was not undetected in fried and vinegarish peanut. Ara h 3 had a stable band pattern in all samples, but there was the most prominent band at 37-40 kDa in vinegarish peanut. The IgE immunoblot assay revealed that 10 min roasted peanut had more IgE binding to Ara h 2, and there was no IgE binding to Ara h 1 in fried and vinegarish peanut. In vinegarish peanut, there was almost no IgE binding to it. CONCLUSION: The results of this study suggest that the roasted peanut may increase the allergenicity of Ara h 2 as compared to Ara h 1. Fried and vinegarish peanut may reduce the allergenicity of peanut.

PURPOSE: The presence of C4d in peritubular capillaries (C4d (PTC)) as a diagnostic in-situ marker of acute humoral rejection and CD20 as marker of B-cell deposition in graft kidney has been reported to be related to steroid resistance and poor outcome. In this retrospective study, we evaluated the clinical significance of C4d and CD20 in allograft renal biopsies by immunohistochemistry technique. And we also evaluated the relationships between C4d and CD20 positive B lymphocytes. METHODS: We studied 22 patients who had been biopsied for suspected acute rejection. Biopsies were classified by updated Banff 97 criteria. Of the 22 cases, borderline rejection and Banff 1A were 11 cases respectively and no case had a vascular lesion. Paraffin sections were stained with monoclonal antibodies (anti-C4d and -CD20) using an immunohistochemistry technique and the results of immunohistochemistry were analyzed by clinical data. RESULTS: Of the 22 cases, 22.7% (5/22) showed diffuse and 40.9% (9/22) showed focal C4d positivity in peritubular capillaries. The grafts failed to survive in 20% (1/5) of the diffuse (P), 44.4% (4/9) of the focal, and 0% (0/8) of the negative group for 2 years since postbiopsies, however, the C4d staining was not statistically related to graft loss and graft survival rates (P=0.091, P=0.106 respectively). The C4d positivity was significantly related to the level of serum creatinine (P=0.042) and to steroid pulsing therapy resistance (P=0.030). However C4d deposition was not associated with recipient gender, age, type of donor (living vs deceased), HLA matching, induction, and Banff classification. On the CD20 immunostaining, 50.0% (11/22) showed negative reactivity, 9.1% (2/22) one nodule, 40.9% (9/22) 2 nodules. The presence and the number of CD20 positive nodules were not correlated to the C4d clinical data. But, the degree of C4d staining was statistically related with the presence of CD20 positive nodules (P=0.029). CONCLUSION: The peritubular capillary C4d is clinically important however, not likely a significant predictor of grafts survival rates in mild rejection. The clinical implication of CD20 positive B lymphocyte nodules in acute rejection was not demonstrated in this study. But, CD20 positive B lymphocyte may be a positive linkage with C4d and participate in humoral rejection.
