Asymptomatic Synchronous Tuberculosis Involving Stomach and Small Bowel in Immunocompetent Patient / 대한소화기학회지

Gastrointestinal tuberculosis that is not an unusual form of extrapulmonary tuberculosis and it is usually associated with immunocompromised condition that may present with clinical symptoms including fever, weight loss or pain. Terminal ileum and cecum are the common sites of involvement, but involvement of the stomach is rare. Furthermore, synchronous tuberculosis involving both the stomach and lower gastrointestinal tract has been reported in very few cases. Herein, we report a case of incidentally detected synchronous tuberculosis involving both the stomach and terminal ileum that was successfully treated by antituberculosis therapy in an asymptomatic immunocompetent patient.

A Case of Paradoxical Reaction Development during Antituberculosis Therapy / 대한소화기학회지

Paradoxical reaction during antituberculosis therapy is defined as aggravation of preexisting tuberculous lesions or the development of new lesions. A 24-year-old female college student diagnosed with abdominal and pulmonary tuberculosis presented with fever and abdominal pain after having been treated with antituberculosis agents for 4 months. Tuberculous mesenteric lymphadenitis was suspected on abdominal CT scan and enlarged necrotic abscess was also present. These findings were considered to be due to paradoxical reaction rather than treatment failure during antituberculosis treatment. Although laparoscopic bowel adhesiolysis and abscess drainage were performed, high fever and severe abdominal pain did not improve. However, the patient eventually made a completely recovery after corticosteroid therapy combined with antituberculosis agents. Herein, we report a case of paradoxical reaction which developed in a patient with abdominal and pulmonary tuberculosis during antituberculosis therapy.

Bond-strength of several metal-meramic alloys and meneered-porcelain / 대한치과보철학회지

PURPOSE: In this study, we evaluated the bond-strength between a few metal ceramic-alloys and veneered-porcelain and found if the bond strength of metal-ceramic alloy with lower gold content than the presently used gold alloy was high enough. MATERIALS AND METHODS: For this study, after plasticizing porcelain only for gold alloy, metal specimen was fabricated using Ni-Cr alloy and gold alloy with different gold content. Three point flexural test were performed to measure their bond-strength. RESULTS: The bonding strength of Group 1 to porcelain was 40.62 +/- 3.32 MPa, which was the highest (P.05), while there was a significant difference between that of Group 2, Group 3 and Group 4 and that of Group 6 (Duncan's test, P<.05). The bonding strength between gold alloy and porcelain increased according to the content of gold. In all experimental groups showed higher value than 25 MPa, which is the least value recommended by ISO 9693. CONCLUSION: In all groups, bonding strength was higher than 25 MPa, which is the least value of ISO9693. Therefore, it is considered that metal gold alloy with low gold content is clinically usable.

Resorption of labial bone in maxillary anterior implant

PURPOSE: The purpose of this study was to evaluate the amount of resorption and thickness of labial bone in anterior maxillary implant using cone beam computed tomography with Hitachi CB Mercuray (Hitachi, Medico, Tokyo, Japan). MATERIALS AND METHODS: Twenty-one patients with 26 implants were followed-up and checked with CBCT. 21 OSSEOTITE NT(R) (3i/implant Innovations, Florida, USA) and 5 OSSEOTITE(R) implants (3i/implant Innovations, Florida, USA) were placed at anterior region and they were positioned vertically at the same level of bony scallop of adjacent teeth. Whenever there was no lesion or labial bone was intact, immediate placement was tried as possible as it could be. Generated bone regeneration was done in the patients with the deficiency of hard tissue using Bio-Oss(R) (Geistlich, Wolhusen, Switzerland) and Bio-Gide(R) (Geistlich, Wolhusen, Switzerland). Second surgery was done in 6 months after implant placement and provisionalization was done for 3 months. Definite abutment was made of titanium abutment with porcelain, gold and zirconia, and was attached after provisionalization. Two-dimensional slices were created to produce sagittal, coronal, axial and 3D by using OnDemand3D (Cybermed, Seoul, Korea). RESULTS: The mean value of bone resorption (distance from top of implant to labial bone) was 1.32 +/- 0.86 mm and the mean thickness of labial bone was 1.91 +/- 0.45 mm. CONCLUSION: It is suggested that the thickness more than 1.91 mm could reduce the amount and incidence of resorption of labial bone in maxillary anterior implant.

Metronidazole-induced encephalopathy in a patient with liver cirrhosis / 대한간학회지

Encephalopathy is a disorder characterized by altered brain function, which can be attributed to various causes. Encephalopathy associated with metronidazole administration occurs rarely and depends on the cumulative metronidazole dose, and most patients with this condition recover rapidly after discontinuation of therapy. Because metronidazole is metabolized in the liver and can be transported by the cerebrospinal fluid and cross the blood-brain barrier, it may induce encephalopathy even at a low cumulative dose in patients with hepatic dysfunction. We experienced a patient who showed ataxic gait and dysarthric speech after receiving metronidazole for the treatment of hepatic encephalopathy that was not controlled by the administration of lactulose. The patient was diagnosed as metronidazole-induced encephalopathy, and stopping drug administration resulted in a complete recovery from encephalopathy. This case shows that caution should be exercised when administering metronidazole because even a low dose can induce encephalopathy in patients with liver cirrhosis.

2 Cases of Submucosal Tumors Caused by Gastric Anisakiasis / 대한소화기내시경학회지

Anisakiasis is a parasitic disease caused by an infection of Anisakinae larvae. It occurs when the live larvae are introduced to the human gastrointestinal tract by eating infected raw fish. The endoscopic features of the gastric mucosa adjacent to the worms include redness, edematous, which are sometimes hemorrhagic and erosive. Gastric anisakiasis forming submucosal tumor, due to unobserved endoscopy, larva is very rare. 2 cases of submucosal tumors caused by gastric anisakiasis were found by endoscopic examination. The well demarcated mass lesion was seen in the submucosal layer of the stomach using endoscopic ultrasonography, and confirmed by laparoscopic wedge resection.

Housewives' Behavior of Purchasing Special Eggs and Cooking Patterns of Eggs in Kyunggi-do and Inchon / 대한지역사회영양학회지

The purpose of this study was to investigate the purchase of special and cooking patterns of eggs. This survey was carried out through questionnaire and the subjects were 435 housewives whose children were middle or high school students in Kyunggi-do and Inchon. The results are summarized as follows : 1) As for age, 66.4% of subjects were 40 years or older. Also 57.1% of subjects received a high school education. As for occuption, full-time housewives accounted for 60.5%. Monthly family income of 39.1 % was 1-2 million won. As for monthly cost of food, 51.7% of subjects paid less than 500 thousand won. Also 40.2% of subjects lived in apartments. 2)Most housewives knew about the sale of special eggs. However, they perceived that the price of special eggs was expensive. 3) The higher their age, education level. household income and food cost, were, the more frequent their purchase of special eggs was. 4) The reason for their purchasing special eggs was in order of nutrition and freshness. 5) Most housewives didn't trust the brands of special eggs. 6) The most popular method of cooking eggs was fried-eggs. Therefore, it is necessary to provide cheap, fresh and nutritious special eggs.
