RESUMEN

BACKGROUND AND AIM: The aim of this study was to evaluate the validity of the parameters of conventional white-light endoscopy and magnifying endoscopy with narrow-band imaging (MENBI) for the prediction of discrepancies between pre- and post-resectional histology in cases of gastric adenoma with low-grade dysplasia (LGD) that were diagnosed based on endoscopically biopsied specimens. METHODS: The medical records of 266 lesions with gastric LGD that were diagnosed by endoscopic forceps biopsies were retrospectively reviewed. The Vienna classification was used for histologic diagnosis. These patients all underwent MENBI examinations followed by analyses of the incidence of histologic discrepancies and histologic heterogeneity. The relationship between white-light endoscopic/MENBI parameters and the presence of histologic discrepancies was also analyzed. RESULTS: Discrepancies between the pre- and post-resectional histologies were found in 74 cases (27.9%). Among those cases, the histology was upgraded in 71 cases, whereas the histology was downgraded in three cases. The presence of erythema and positive MENBI findings were independent factors for the prediction of upgraded histologic discrepancies (P-values = 0.008, < 0.001, respectively). A positive MENBI finding yielded the highest predictive value, with a multivariate adjusted odds ratio of 42.46. Histologic heterogeneity in post-resectional specimens was found in 40.8% of cases with upgraded histologic discrepancies. CONCLUSIONS: MENBI can provide more accurate information than white-light endoscopy for the prediction of pre- and post-resectional histologic discrepancies in biopsy-proven gastric LGD. Endoscopic resection is strongly recommended in cases with surface erythema on conventional white-light endoscopy or positive MENBI, irrespective of the lesion size.

RESUMEN

BACKGROUND AND AIM: This study was conducted to determine the clinicopathologic factors affecting the stage of ulcerative early gastric cancer (EGC), focusing on the relationships between cancer stage and degree of endoscopic ulcer depth and morphologic changes. METHODS: Medical records of 183 cases of ulcerative EGC who had received endoscopic examination two or more times with a minimum interval of one week, and who underwent either curative surgery or endoscopic treatment were retrospectively reviewed. RESULTS: Change in ulcer morphology at follow-up endoscopy was observed in 84 cases (45.9%) with improvement and exacerbation of ulcer in 65 (35.5%) and 19 (13.8%) cases, respectively. The presence of type III ulcer (P < 0.01), and endoscopic findings suggesting submucosal cancer invasion (tumorous bank, fusion of converging folds, hardness or decreased flexibility) (P < 0.01), and incomplete ulcer healing (P = 0.036) were independently associated with a higher incidence of submucosal cancer invasion. The incidence of lymph node metastasis was 14.1%, and undifferentiated histology and presence of lymphovascular invasion were significantly associated with a higher incidence of lymph node metastasis (P = 0.018 and P = 0.005, respectively). CONCLUSIONS: Endoscopic resection with curative intent may be an acceptable option for EGC combined with endoscopic ulcer or ulcer scar, but should be restricted to cases showing significant improvement in the size and depth of ulcer at follow-up endoscopy, and which are not accompanied with deep ulcer more than the thickness of adjacent mucosal surface and prominent surrounding mucosal fold change. In addition, histologic criteria should meet the conditions of differentiated intramucosal cancer without lymphovascular invasion.

RESUMEN

Toxic hepatitis has been reported as a major cause of acute hepatitis, but its potential induction by herbal remedies and/or health foods is usually neglected. We experienced a case of toxic hepatitis associated with Polygoni multiflori, a Chinese herb commonly known as Ho-Shou-Wu. A 54-year-old woman consumed Ho-Shou-Wu for 1 month, after which she experienced fatigue and overall weakness. A diagnosis of toxic hepatitis was made based on her clinical history, the findings for viral markers and other laboratory data, and ultrasonography. Her condition improved considerably after she stopped taking Ho-Shou-Wu. However, she resumed taking Ho-Shou-Wu immediately after discharge from hospital, which aggravated her symptoms and liver function. She was immediately readmitted and stopped taking Ho-Shou-Wu. Her relapse into hepatitis immediate after resuming consumption of the herb is strongly indicative of the validity of Koch's postulate in this case.

RESUMEN

Fitz-Hugh-Curtis syndrome has been described as focal perihepatitis accompanying pelvic inflammatory disease caused by Neisseria gonorrhea and Chlamydia trachomatis. The highest incidence occurs in young, sexually active females. However, the syndrome has been reported to occur infrequently in males, according to the foreign literature. The predominant symptoms are right upper quadrant pain and tenderness, and pleuritic right sided chest pain. The clinical presentation is similar in men and women. In women, the spread of infection to liver capsule is thought to occur directly from infected fallopian tube via the right paracolic gutter. In men, hematogenous and lymphatic spread is thought to be postulated. Recently, we experienced a case of Fitz-Hugh-Curtis syndrome occurred in a man. As far as we know, it is the first report in Korea, and we report a case with a review of the literature.

RESUMEN

Pomegranate (Punica granatum) seed linolenic acid isomers were evaluated as selective estrogen receptor modulators (SERMs) in vitro. Punicic acid (PA) inhibited (IC(50)) estrogen receptor (ER) alpha at 7.2 microM, ERbeta at 8.8 microM; alpha-eleostearic acid (AEA) inhibited ERalpha/ERbeta at 6.5/7.8 microM. PA (not AEA) agonized ERalpha/ERbeta (EC(50)) at 1.8/2 microM, antagonizing at 101/80 microM. AEA antagonized ERalpha/ERbeta at 150/140 microM. PA and AEA induced ERalpha and ERbeta mRNA expression in MCF-7, but not in MDA-MB-231. Overall, the results show PA and AEA are SERMs.
