RESUMO
It has been reported that ingestion of raw or undercooked shiitake mushrooms is associated with various adverse food reactions. A 58-year-old man presented with pruritic and maculopapular rashes on the trunk and extremities starting 1 day after ingestion of partially uncooked shiitake mushrooms. A probable diagnosis of systemic allergic contact dermatitis was made. Raw and cooked shiitake mushroom-derived allergen extracts were prepared, and patch and intradermal tests with delayed readings were performed. The case showed positive intradermal test results with delayed readings to the raw, but not cooked, extracts. The case suggests that ingestion of uncooked shiitake mushrooms may induce systemic allergic contact dermatitis through type IV hypersensitivity reaction.

Stevens-Johnson syndrome (SJS) manifests with severe cutaneous reactions, most commonly triggered by medications, which are characterized by fever and mucocutaneous lesions leading to necrosis and sloughing of the epidermis. To our knowledge, pravastatin-induced SJS has not yet been reported. Here, we describe a case of SJS due to pravastatin, which was diagnosed by a patch test. A 70-year-old woman presented with maculopapular skin rashes, which developed 2 weeks after medication of bisoprolol, amlodipine, pravastatin, spironolactone, and indobufene for cardiac problems. Various bullous-erosive mucocutaneous lesions occupied less than 10% of the total body surface area. Painful oropharyngeal mucous membrane lesions were observed. The vermilion border of the lips became denuded and developed serosanguinous crusts. With the drug withdrawal and the use of systemic corticosteroids, her manifestations resolved. Drug patch tests with bisoprolol, amlodipine, pravastatin, spironolactone, and indobufene were performed, resulting in a positive reaction to pravastatin, but not to the other drugs. To the best of our knowledge, this is the first case of pravastatin-induced SJS.

BACKGROUND/AIMS: To evaluate the efficacy of proton pump inhibitors (PPIs) in reducing rebleeding and bleeding-related death rates after endoscopic gastric variceal obliteration (GVO) using N-butyl-2-cyanoacrylate (NBC). METHODS: This study enrolled 341 patients who were consecutively diagnosed with and treated for bleeding gastric varices. The patients were divided into PPI and non-PPI groups, and their endoscopic findings, initial hemostasis outcomes, rebleeding and bleeding-related death rates, and treatment-related complications were analyzed. RESULTS: The rate of initial hemostasis was 97.1%. rebleeding occurred in 2.2% of patients within 2 weeks, 3.9% of patients within 4 weeks, 18.9% of patients within 6 months, and 27.6% of patients within 12 months of the GVO procedure. A previous history of variceal bleeding (relative risk [RR], 1.955; 95% confidence interval [CI], 1.263 to 3.028; p = 0.003) and use of PPIs (RR, 0.554; 95% CI, 0.352 to 0.873; p = 0.011) were associated with rebleeding. Child-Pugh class C (RR, 10.914; 95% CI, 4.032 to 29.541; p < 0.001), failure of initial hemostasis (RR, 13.329; 95% CI, 2.795 to 63.556; p = 0.001), and the presence of red-colored concomitant esophageal varices (RR, 4.096; 95% CI, 1.320 to 12.713; p = 0.015) were associated with bleeding-related death. CONCLUSIONS: The prophylactic use of PPIs reduces rebleeding after GVO using NBC in patients with gastric variceal hemorrhage. However, prophylactic use of PPIs does not reduce bleeding-related death.

Hypoganglionosis is a rare form of intestinal neuronal malformation, which is characterized by reduced number and size of ganglion cells of parasympathetic nerves in the intestinal wall. Pathophysiology is not well known, however intestinal ischemia, inflammation, autoimmune process or neurotoxin may play a role. Here, we report the case of a 56-year-old man with colonic pseudoobstruction and ulcerations in marked dilatedcolon above transitional zone who was later diagnosed with colonic hypoganglionosis.

BACKGROUND/AIMS: To evaluate the long-term efficacy and safety of endoscopic injection of N-butyl-2-cyanoacrylate (NBC; Histoacryl) for treatment of bleeding gastric varices. METHODS: We retrospectively analyzed the records of 455 patients with gastric variceal hemorrhage (GVH) who were consecutively treated with NBC from January 2004 to July 2013, with a mean follow-up period of 582 days. The patients' endoscopic findings, initial hemostasis, complications, rebleeding rates, and bleeding-related death rates were reviewed. RESULTS: Hemostasis was achieved initially in 96.9% (441/455) of patients; rebleeding occurred in 35.2% (160/455), and the bleeding-related death rate was 6.8% (31/455) during follow-up. Complications included fever (6.8%), abdominal pain (3.7%), diarrhea (1.3%), spontaneous bacterial peritonitis (0.7%), bacteremia (0.4%), and embolism (0.2%). A red-color sign on concomitant esophageal varices (EVs) (p = 0.002) and previous history of variceal bleeding (p < 0.001) were significant risk factors for rebleeding within 1 year. The Child-Pugh score (p < 0.001), presence of hepatocellular carcinoma (p = 0.001), and failure of initial hemostasis (p < 0.001) were the risk factors most closely associated with bleeding-related death. CONCLUSIONS: This study provides a comprehensive overview of the outcomes and prognostic factors of patients with GVH. The results may help in the selection of effective treatment strategies for patients with GVH.
