Ten cases with esophageal foreign body were treated surgically from July 1980 to October 1995 at the Department of Thoracic and Cardiovascular Surgery, Chungnam National University Hospital. The mean age was 45.3 years, with a range from 25 to 71. Out of ten cases, 6 were female and four were male. Common symptoms were dysphagia, fever, foreign body sensation and neck pain. Three cases of foreign bodies were of fish bones, two of bubble package of drugs, one case of a beer bottle cap, one of a piece glass, one of a bathtub plug, one of chicken and one of a bean. The diagnosis was established by esophagography using a water soluble contrast material and esophagoscopy. Among of ten cases, two had esophageal stricture due to the ingestion of lye at a young age. One case had experienced psychological problems. All foreign bodies were removed by surgical procedures. Five cases were treated by cervical esophagostomy, one case by right thoracotomy, one case by retrograde bougienation through gastrostomy and two cases by cervical incision and drainage for cervical abscess. Three cases developed post operative esophageal leaks which healed spontaneously and transient hoarseness developed in one case. One case developed traumatic pneumothorax and subcutaneous emphysema which was treated by closed thoracostomy. There were no operative deaths.

Malignant schwannoma is rare tumor which is derived from schwan cells or nerve sheath cells, and it is frequently associated with Von Rechlinghausen's disease. We experienced one case of malignant schwannoma on the right chest wall without Von Rechlinghausen's disease. Patient was 64-year-old man who presented painless palpable mass on the right lower chest wall for about 2 months. On chest computed tomography, the mass which was 6 X 6 cm in size and had central necrosis, involved 11th rib with destruction, invaded the diaphragm and displaced the kidney anteriorlly. He underwent en-bloc resection of the tumor and discharged without any problem after 20 days.

PURPOSE: The purpose of this study was to evaluate the clinicopathological features and immunohistochemical features of gastrointestinal stromal tumor (GIST), and specifically the expressions of platelet derived growth factor receptor A (PDGFRA), protein kinase C theta (PKC theta), discovered on GIST-1 (DOG-1), p16 and p27. MATERIALS AND METHODS: Total 118 patients who underwent surgical resection for GIST at our institution between Jan 1997 and Dec 2007 were retrospectively studied. Immunohistochemical staining for c-kit, PDGFRA, PKC-theta, DOG-1, p16 and p27 was performed on a tissue microarray of the 118 GIST. The clinicopathologic parameters, the disease-free survival (DFS) and the overall survival rate were analyzed along with immunohistochemistry. RESULTS: The immunohistochemical stains for c-kit, CD34, PKC-theta, PDGFRA, DOG-1, p16 and p27 were positive in 89.8%, 72.0%, 56.8%, 94.9%, 90.7%, 69.5% and 44.1% of the tumor samples, respectively. The immunohistochemical expression of c-kit was strongly correlated with PKC-theta (p=0.000), DOG-1 (p=0.000) and CD34 (p=0.002). The DFS rate was significantly decreased for the patients with peritoneal GIST, high risk GIST, > or =10 cm-sized GIST, > or =10 mitoses/50 high power fields (HPFs) and p16 positivity (p=0.001, p=0.004, p=0.001, p=0.003 and p=0.028). GISTs > or =10 cm, epithelioid tumor cell type, and c-kit, and DOG-1 negativity were significantly associated with shorter period of overall survival (p=0.048, p=0.006, p=0.000 and p=0.000). CONCLUSION: The expression of p16 and no expression of c-kit and DOG-1 in GISTs, as well as peritoneal tumor site, high risk group, large tumor size, epithelioid tumor cell type and numerous mitoses, may be potentially prognostic factors for predicting worse outcome for patients who suffer from GIST.

Duplication cysts are rare congenital malformations, that may be detected anywhere along the alimentary tract, and they may communicate with the intestinal tract. Cystic duplication of the cecum is especially rare. About 80% of these cases are detected in the first 2 years of life as a result of an acute intestinal obstruction, which manifests as vomiting, recurrent abdominal pain, recurrent gastrointestinal bleeding and constipation. We report a case of intestinal obstruction secondary to a duplication cyst of the cecum in a neonate. The patient underwent surgery and was diagnosed subsequently, and is presently healthy.

Churg-Strauss syndrome (CSS) is a disorder characterized by pulmonary and systemic small- vessel vasculitis, extravascular eosinophilic infiltration and hypereosinophilia; it is rarely diagnosed in the pediatric age group. We experienced a case of CSS in a male infant who had repeated symptoms of asthma with hypereosinophilia and transitory non-fixed pulmonary infiltrates on chest radiographs. He also had rectal bleeding in early infancy and multiple erosions with extravascular eosinophilic infiltrations in the sigmoid colon. We report a rare case of CSS in a 14-month-old infant and review the medical literature.

PURPOSE: The aim of this study was to determine the clinical significance of food-specific IgE antibody tests in detecting triggering antigens in food protein-induced proctocolitis (FPIPC). METHODS: Between February 2006 and May 2007, data from 16 consecutive FPIPC patients that underwent MAST and Uni-CAP tests on initial visits, were reviewed. The endoscopic criterion used for establishing a diagnosis of FPIPC was an increase in the number of eosinophils in the lamina propria (> or =60 per 10 high power fields). Offending foods were suspected clinically based on elimination and challenge testing to mother or patient diets with the following five highly allergenic foods: dairy products, eggs, nuts and soybean, fish and shellfish, and wheat and buckwheat. We compared the results of initial MAST or Uni-CAP tests with clinically suspected offending foods. RESULTS: For the 16 FPIPC patients, MAST tests showed positive results in 2 patients (12.5%), and Uni-CAP tests showed positive results in 3 patients (18.8%). Through clinical elimination and challenge, the 33 offending foods were identified: 7 fish and shellfish (21.2%), 6 eggs (18.2%), 6 wheat and buckwheat (18.2%), 4 dairy products (12.1%), 3 soybean (9.1%), 3 pork (9.1%), 2 nuts (6.1%), 1 beef (3.0%), and 1 mushroom (3.0%). Clinically suspected offending foods and MAST and Uni-CAP test results were found to be correlated in 1 patient (6.7%) each. CONCLUSION: Food specific IgE antibody tests are inappropriate for predicting offending foods in FPIPC. Clinical food elimination and challenge testing provide useful means of detecting offending foods.

Cyclosporine nephropathy was induced by intraperitoneal injection of cyclosporine 25 mg/kg in Sprague-Dawley rats daily for 1, 4, 8, and 12 weeks to clarify the relationship between cyclosporine nephropathy and the expression of TGF-beta1 with extracellular matrix deposition. On light microscopic examination, the kidneys in the 12 week cyclosporine-treated rats showed focal or striped fibrosis, vacuolization of tubular cells, and injury of endothelial cells. Immunohistochemically, TGF-beta1 protein was strongly expressed in the cyclosporine-treated rat kidneys, especially in the glomerular endothelial cells, interstitial endothelial cells, tubular epithelial cells, and parietal cells in the Bowman's capsule of the glomerulus as well as the periglomerular arterioles. The amount of TGF-beta1 expression was correlated with the morphological change in the cyclosporine-treated rats. Extracellular matrix, such as fibronectin and collagen IV, was also expressed in the endothelial cells of the glomerulus and the interstitium. It can be concluded, therefore that TGF-beta1 protein is probably involved in the early stage of fibrogenesis in cyclosporine nephropathy. It can be postulated that cyclosporine nephropathy results from the accumulation of extracellular matrix associated with the increase of TGF-beta1 transcription. Therefore, these results could be used in reducing fibrosis in cyclosporine nephropathy.

Transposition of the island pedicle flap is a versatile method of mobilizing tissue from a relatively distant reservoir and moving it across intervening tissue. Advantages are the similar color and texture to those of the affected area, the minimal donor scar, the increased viability with local blood supply, and the potential to camouflage scars into natural skin lines or cosmetic units. In a 73-year-old woman, the lesion of a basal cell carcinoma on her left nasal ala was removed by Mohs micrographic surgery and the resultant defect was reconstructed by transposition of the island pedicle flap. In our case, there were no significant complications and the final result was satisfactory in both functional and cosmetic aspects. Through our experience, we can confirm that transposition of the island pedicle flap is another alternative for the reconstruction of nasal alar defects.

BACKGROUND: Although ablative fractional resurfacing is known to be effective against photoaging and acne scars, studies on its efficacy, safety and changes in the skin characteristics of Asians are limited. OBJECTIVE: The aim of this study is to assess the efficacy and safety of carbon dioxide fractional laser (CO2FL) in Koreans treated for wrinkles and acne scars, and to define the changes in skin characteristics during recovery period. METHODS: We administered one session of CO2FL on 10 acne scar patients and 14 wrinkles patients with skin types IV and V. The surveillance of efficacy and side effects along with the measurement of biophysical properties was carried out before 1 day, 1 week, 1 month and 3 months after treatment. RESULTS: Using a non-invasive method, skin barrier damage, erythema and bronzing of skin during the recovery period were assessed, and all of the items eventually returned to the pre-treatment level. Skin elasticity was measured in the wrinkle group, and the statistically significant effect was sustained throughout the next three months. The outcome of treatment was found to be better than 'moderate improvement' in both the acne scar and wrinkle groups. Further, there were no serious side effects three months post-procedure. CONCLUSION: CO2 FL is thought to be an effective and safe method for treating moderate to severe acne scars and wrinkles in Asians.
