Parvimonas micra is a non-spore-forming anaerobic gram-positive coccus and a known commensal of the skin, gums, vagina, and gastrointestinal tract. It is rarely associated with severe infections, which typically follow invasive procedures such as dental treatment. We describe a case of a brain abscess caused by P. micra in an immunocompetent 11-year-old boy without periodontal disease. He presented with a 7-day history of headaches and vomiting, and complained of diplopia that began on the day of presentation. He did not have any recent dental treatment or specific past medical history. A brain abscess in the left frontoparietal lobe was noted on brain magnetic resonance imaging. P. micra was cultured from brain abscess aspirate. He was successfully treated with surgical drainage and combined antibiotic therapy with ceftriaxone and metronidazole for 6 weeks.

Endoscopic diagnosis and medical management from K43 and C45 patients, whose sex, occupation, character and life patterns are quite different each other, were discussed. The K43 was patient with erosive gastritis, which may caused by maldietary habits and life stresses. Although the effective drugs such as H2-receptor antagonists with atacids, H+/K+-pump inhibitors, prokinetics, colloidal bismuth, and sucralfates, were administrated for long time, symptomatic relief of abdominal pain was not improved. The tests of clinical phathology and abdominal sonogram were normal, visceral hypersensitivity was appeared from barostat test of stomach. However C45 had taken headache during every day life, and endoscopically confirmed as a gastric·duodenal ulcer patiant, which may caused by chronic use of NSAIDs. The her ulceric symptoms were suppressed from active stage to healing stage by using combination therapy for H. pylori with traditional antipeptic ulcer drugs, where as amitriptyline was administrated to the K43 but not effective. Nonulcer dyspepsia and irritable bowel syndrome is pooly defined, and affect about 15% of the population annually in U. S. A. but don't seek medical care. Author would like to point out that statistics for visceral pains are absent in Korea.

식도 천공의 치료는 최근 치료법의 발전에도 불구하고 여전히 난해한 문제이다. 이 환자들은 천공의 원인이나 위치, 심한 정도가 다양한 이질적인 군이며, 반수 이상이 이미 식도에 기존의 질환을 가지고 있어 문제를 더욱 복잡하게 한다. 따라서 절대적이고 획일적인 치료방법은 아직 확립되어 있지 않으며 많은 다양한 방법들이 제시되고 있다. 2002년 11월부터 2003년 7월까지 총 8명의 환자가 식도 천공으로 동아대학교병원 흥부외과에서 치료를 받았으며, 원인별로는 의인성(iatrogenic) 손상이 6례, 자발성(spontaneous) 손상이 2례였고 부위별로는 경부가 3례, 흥부가 5례였다. 의인성 손상에는 내시경 검사중 정상 경부 식도에 발생한 1례, 부식성 식도협착 환자의 풍선 확장술과 스텐트 삽입시 흉부 식도에 발생한 경우가 각각 1례씩, 외상성 경추손상의 수술시 정상 경부 식도에 발생한 경우가 2례, 선천성 식도폐쇄증(esophageal atresia)의 술후 문합부 누출이 생긴 경우가 1례 있었으며, 자발성 손상에는 하부식도에 발생한 기압성(barogenic) 손상 1례와 상흉부 식도암 천공 1례가 있었다. 경부 식도 천공 3례는 모두 경부 배액(drainage)과 식이용 장루술(feeding jejunostomy)을 시행하였고, 부식성 식도협착이 있던 환자 2례는 식도절제술과 흉부내 식도-위 문합을 시행하였으며, Boerhaave씨 증후군 환자는 1차 봉합술, 술후 문합부 유출이 있었던 환자와 식도암 천공이 있었던 환자는 식도절제 및 경부 식도루(esophagostomy), 배액용 위루(gastrostomy), 식이용 장루술을 시행하였다. 모든 환자는 패혈증 등의 심각한 합병증으로의 진행 없이 회복되었다. 현재 위장관의 연속성이 유지 혹은 복원된 환자는 경구식이 중이며 그 외의 환자들은 장루를 통해 영양을 공급하며 식도재건술을 기다리고 있다. 식도 천공은 최근 항생제의 사용, 과영양요법(hyperalimentation), 술후 환자관리의 개선 등으로 치료에 많은 발전이 있었으나, 치료 방침에 있어서는 여전히 논란이 있으며 높은 사망률을 보이는 난제로 남아있다. 비록 일반적인 지침이 도움이 되겠지만, 치료 방침은 환자 개개인의 상황에 따라 적절하게 선택해야 하며, 임상경과에 따라 언제라도 방침을 변경할 수 있는 유연함이 필요하리라 생각한다.

Streptococcus intermedius is a small, non-motile, Gram-positive, non-sporeforming, and aerotolerant anaerobic coccus. It is a part of the normal microflora in the oral cavity and upper respiratory, gastrointestinal and female urogenital tracts. It is an opportunistic pathogen that causes serious infections in patients with immunocompromised states or cardiac diseases as a result of trauma or invasive procedures. We describe a case of septic arthritis of the hip caused by S. intermedius in an immunocompetent healthy 7-year-old boy without a history of periodontal disease or invasive procedures. He had hip joint pain three weeks ago, and the fever began on the day of the visit. He had been healthy and had not undergone any invasive procedures recently. Septic arthritis of the hip was indicated in the magnetic resonance imaging of the hip. S. intermedius was identified in the hip joint fluid aspiration and blood culture. He was successfully treated with surgical intervention and antibiotic therapy with ceftriaxone followed by amoxicillin for five weeks.

Inflammatory pseudotumors (IPTs) are uncommon, mass-forming lesions, predominantly involving the lung and orbit. Although the incidence of IPTs is rare in the abdomen and pelvis, they can be encountered as enhancing, soft-tissue lesions, mimicking malignancy or fibrosclerosing disease. Generally, they exhibit a wide range of nonspecific imaging features in various organs. Preoperative imaging diagnosis of IPTs in appropriate clinical settings may help determine proper patient management. In this article, we review radiologic findings of IPTs in the abdominopelvic cavity, including the liver, spleen, kidney, gastrointestinal tract, mesentery, pelvis, and retroperitoneum.

Malrotation and midgut volvulus are surgical emergencies that commonly occur within the first month of life. The classic symptom is acute bilious vomiting, while nonspecific symptoms such as recurrent abdominal pain may be present in older children. Malrotation can be associated with duodenal obstruction caused by an abnormal peritoneal fibrous band or congenital anomalies, such as an annular pancreas or a preduodenal portal vein. Volvulus can lead to bowel ischemia and a life-threatening condition, thus prompt and accurate diagnosis is crucial. Diagnosis can be made through upper gastrointestinal series, ultrasonography, and CT, with ultrasonography being preferred as a screening tool due to its rapid and accurate diagnosis, without radiation exposure, in children. This pictorial essay discusses the key imaging findings and diagnostic approaches for malrotation and midgut volvulus, as well as diagnostic pitfalls based on actual cases.

Isolated left-sided portal hypertension is a rare clinical syndrome caused by splenic veno-occlusive disease. Splenic vein thrombosis and extrinsic compression causes proximal splenic vein hypertension, and the splenic blood flows into the superior mesenteric or portal vein through the upper stomach's collateral vessels, such as the short gastric, coronary, and gastroepiploic veins. Open splenectomy is recommended to treat gastrointestinal bleeding caused by isolated left-sided portal hypertension. Interventional management could be a clinically useful option for selected patients who want to avoid surgical corrections. The report presents two cases of left-sided portal hypertension with gastric variceal bleeding.

Recently, much attention has been paid to the development of a value-added food category containing probiotics so as to improve human health and prevent diseases. Among various foods, the health benefits of milk and dairy products are known to humanity, and could be attributed to the bioactive components present in milk. In fermented milk products, the health benefits could be due to suitable modulation activities produced by the action of probiotic bacteria. Besides the modification of various milk components, probiotics might also act directly as preventive and therapeutic agents against some severe diseases. Probiotics promote health via their positive effects on the immune response, stimulation of natural immunity, and modulation of the production of antimicrobial peptides, cytokines, and so on. Whey proteins, a byproduct of cheese production could also have anticarcinogenic, immunostimulatory, antimicrobial, and health-promoting activities such as improving insulin sensitivity and reducing fat deposition. Therefore, milk and dairy products containing probiotics could provide various opportunities in the field of functional foods. Additionally, these functional foods may be important in the human diet and may help improve human health and prevent diseases.

We experienced a case of upper esophageal leiomyoma successfully excised by thoracoscopic surgery. A 29-year-old male was presented with retrosternal discomfort and mild dysphagia and an esophagogram revealed smooth fElling defect In the upper third of the intrathor cic esophagus, and esophagoscopy showed a submucosal tumor without mucosal infiltration. Chest CT and MRI were performed to confirm size, character and location of the esophageal mass, the absence of infiltration of surrounding structures, and to define mediastinal Iymphadenopathy. The tumor was excised by thoracoscopic surgery and it was diagnosed as leiomyoma (4$\times$2xlcm in size). The postoperative course was uneventful.
