Uterine torsion is defined as the mtation of more than 45 degrees around the long axis of the uterus or a rotation which is severe enough to produce symptoms. Torsion of the human pregnant uterus is a very rare complication. The diagnosis is problematic and is often made during a cesrean section due to inhibited labor. Torsion of the human pregnant uterus can be caused by myoma or other uterine abnormalities, ovarian cysts, adhesions, abnormal fetal presentations, or fetal abnormalities ( though no cause can be found in about 20% of cases ). Uterine torsion produces symptoms of varying severity depending on the degree of rotation, and duration of the pregnancy. High mortality rates for both mother and infant have been reported. We experienced one case of the torsion of term pregnant uterus and report this case with a brief review of the concerned literature.

A primary pulmonary malignant lymphoma is a rare disease. It is thought to be a category of non-Hodgkin's lymphoma arising from the bronchous-associated lymphoid tissue (BALT). The majority of primary pulmonary lymphomas are low-grade, small B-cell lymphomas, which are associated with Sjogren's syndrome and similar autoimmune disorders. A case of primary pulmonary low-grade B-cell lymphoma arising from the BALT was encountered in a patient with systemic lupus erythematosus. A 54-year-old man was admitted to the hospital for the evaluation of left pleuritic chest pain and multiple joint pain in both hands. Serologic tests for collagen vascular disease were performed. The results of ANA and anti-ds-DNA were all positive. The computed tomography of the chest showed patchy concolidations in the left lower lobe with a pleural effusion and a video-assisted thoracoscopic biopsy was performed. Here we report a case of low-grade B-cell lymphoma of BALT in a patient with systemic lupus erythematosus with a review of the relevant leteratures.

BACKGROUND: To assess the utility of HRCT in the evaluation of visceral pleural invasion and to determine whether visceral pleural invasion and bronchovascular bundle thickening on the same lobe could be related to the recurrence and survival in non-small cell lung cancer (NSCLC). METHOD: Eighty one patients, which were fulfilled long-term follow-up at least 18 months (maximum 103 months) among which 434 patients had underwent curative surgical resection for NSCLC from 1986 to 1995, were studied. They were analyzed to evaluate whether the prognostic factors such as the recurrence and survival depend on visceral pleural invasion and bronchovascular bundle thickening to the same lobe. Thirty two patients adjacent to a chest wall or a fissure were evaluated for visceral pleural invasion by HRCT. CT criteria included abutting pleura along the chest wall, abutting and/or compressing fissure, crossing fissure, and pleural tail. RESULTS: The positive predictive value and the negative predictive value of crossing fissure were 100% and 100%, respectively. Two patients showing spiculated interface between a mass and abutting fissure were confirmed to have visceral pleural invasion at surgery. Visceral pleural invasion confirmed at surgery was significant to local recurrence and survival (p<.05, p<.05, respectively). Brochovascular bundle thickening to the same lobe on CT scan was significant to survival (p<.05) but was not significant to local and distant recurrence (p>.05). CONCLUSION: Visceral pleural invasion and bronchovascular bundle thickening to the same lobe have a role in predicting prognosis such as recurrence and survival in NSCLC. Therefore, the analysis of visceral pleural invasion on CT scan and the pathological analysis of bronchovascular bundle thickening to the same lobe may be necessary to predict the prognosis in NSCLC.

Administration of kainate (KA) results in the induction of epileptiform activity and limbic motor seizures. Nitric oxide (NO) is a gaseous messenger that plays a role in neural transmission, long term potentiation, depression and cerebral blood flow. NO is formed by NO synthase (NOS) from arginine. NO mediates the increase in cerebral blood flow during seizure activity. However, the production site of NO has not been clearly defined. Recent report showed that constitutive NOS may be induced under certain conditions. Therefore, the present study was aimed to investigate the change of NOS and calbindin D28k in the rat cerebral cortex following seizure. Rats were injected with KA and killed at 6 hours, 1, 3, 6 and 12 days after seizure. Expressional change of nNOS and calbindin D28k was assessed by histochemistry, immunohistochemistry and RT-PCR in the rat brain. Induced NADPH-d positive neurons were observed in the cerebral cortex of 1, 3, 6 and 12 days after seizure and found in specific cortical areas, such as motor cortex, somatosensory cortex, auditory cortex, visual cortex, ectorhinal cortex and perirhinal cortex. The level of nNOS mRNA increased at 1, 3, 6 and 12 days after seizure compared with control group. Induced calbindin D28k positive neurons were observed in motor cortex and somatosensory cortex 1 and 3 days after seizure. The level of calbindin D28k mRNA in the cerebral cortex was slightly decreased at 1 day after seizure. Therefore, in this study, the induced NADPH-d, calbindin D28k positive neurons and upregulated NADPH-d positive neurons may influence the cerebral blood flow and neuronal activity in the cerebral cortex during post-seizure period.

Ectopic opening of the common bile duct (CBD) in the duodenal bulb is not an incidental finding, but a pathologic condition that can be associated with clinical entities, such as recurrent duodenal ulcer, choledocholithiasis. or cholangitis. We report a case of ectopic CBD with hematemesis in a 61 year-old male patient. Esophagogastroduodenoscopy showed several active ulcers with a fresh blood clot at the duodenal bulb, which had a mucosal deformity and a small opening with suspicious drainage of bile, and the second part of the duodenum had no papilla-like structure. MRCP showed a trident-like pancreatobiliary tree. The biliary tree was visualized via a suspicious ectopic opening of the bile duct at the duodenal bulb. The distal CBD looked hook-shaped and had no filling defect. We report a unique case of ectopic opening of the CBD in the duodenal bulb, which presented as hematemesis.

BACKGROUND/AIMS: Recent guidelines strongly recommend that the interval of surveillance colonoscopy be determined according to the risk stratification obtained at index colonoscopy. However, because of the differences in perception of the classification of colorectal intraepithelial neoplasia between Asian and Western countries, there is some confusion about surveillance colonoscopy. The aim of the present study was to evaluate the clinicopathological characteristics and the interval of surveillance colonoscopy between patients with high-grade dysplasia/carcinoma in situ and those with intramucosal carcinoma. METHODS: From January 2003 to June 2010, 727 patients were included from 8 tertiary centers. Four hundred fifteen patients (57.1%) had high-grade dysplasia/carcinoma in situ (group A), and 312 (43.9%) had intramucosal carcinoma (group B). Clinicopathological data were reviewed retrospectively. RESULTS: Group A had a significantly more frequent family history of colorectal cancer (3.1% vs. 0.6%, P<0.001), smaller polyp size (12 mm vs. 15 mm, P=0.001), and more proximal location (31.1% vs. 21.8%, P=0.005) than did group B. Among 727 patients, surveillance colonoscopy was performed within 6 months in 55.8% of patients and within 12 months in 77.8%. Group B had a significantly shorter interval of surveillance colonoscopy than did group A (P<0.001). There was no difference in detection of advanced neoplasia at surveillance colonoscopy between the 2 groups (6.6% vs. 5.4%, P=0.638). CONCLUSIONS: The recommended interval of surveillance colonoscopy is not followed in Korea. More education about post-polypectomy surveillance guidelines is required.

BACKGROUND: Nowadays it is considered that increment of hematocrit in chronic renal failure patients improves quality of life and cognitive function. But previous studies cannot exclude the practice effect and suggestion because they were accessed in the same ways before and after the erythropoietin treatment. This study was designed into two groups by hematocrit levels to know if patients with higher hematocrit levels have better quality of life and neurocognitive function. METHODS: Fifty-two chronic renal failure patients during hemodialysis received neurocognitive function test by physician before checking several self rating scales about quality of life. RESULTS: Patients with higher hematocrit levels had better scores in neurocognitive function tests and there was a relationship between the age and cognitive function. But patients with higher hematocrit levels didn't have better quality of life than those with lower ones. Instead there was strong correlation between the Beck Depression Inventory score and quality of life. CONCLUSION: These findings suggest that higher hematocrit levels improve cognitive function in chronic renal failure patients on hemodialysis, but increased hematocrit level does not always mean the better quality of life. Other psychological managements for depressive moods are recommended for better quality of life.
