RESUMO
Lamotrigine is an anticonvulsant drug used to treat partial and generalized seizure disorders. Hypersensitivity to lamotrigine usually causes mild symptoms such as fever, rash, and slight invasion of internal organs. However, a 33-year-old male patient who was admitted with Stevens-Johnson syndrome after taking lamotrigine for 15 days experienced hepatic failure and died 5 days after admission. This case demonstrates the importance of realizing that lamotrigine can lead to fatal hepatic failure, and that tests for the normal liver function should be performed when administering lamotrigine.

Xanthogranulomatous cholecystitis (XGC) is a rare type of chronic inflammation of the gallbladder characterized by focal or diffuse destructive inflammatory responses. Although it is a benign condition, its destructive course may lead to more aggressive outcomes of the gallbladder, such as local infiltration, fistula, stricture, and perforation as compared with other gallbladder inflammations. There are reports about XGC accompanied by cholecystoenteric fistula. However, XGC accompanied by more than one cholecystoenteric fistula is rare. We report a case of a 54-year-old man with gastric outlet obstruction arising from XGC, accompanied by cholecystoduodenal fisula and cholecystocolonic fistula, but without impacted gallstones.

The use of traditional folk remedies is increasing throughout Asia. Chelidonium majus, a popular herbal remedy, is used to treat abdominal pain caused by various gastrointestinal disorders, including gastric ulcer, gastritis, and biliary tract disease, because of its morphine-like effect. We encountered a 62-year-old woman with acute hepatitis, in which C. majus was suspected to be the etiological factor. The patient had taken high dose of C. majus extract for the preceding 60 days. The clinical context and the temporal association between the start of the herbal medicine treatment and her liver injury allowed us to attribute a causative role to C. majus. The diagnosis was confirmed by liver biopsy and the Council for International Organizations of Medical Sciences/Roussel Uclaf Causality Assessment Method (CIOMS/RUCAM) scale. After C. majus was discontinued, the liver function was restored to normal. In conclusion, because the use of phytotherapy is increasing, we wish to raise awareness of the potential adverse effects of C. majus.

Hyponatremia is an electrolyte abnormality commonly found in clinical practice. It is important to diagnose the underlying etiology of the hyponatremia and correct it appropriately because severe hyponatremia can cause serious complications and substantially increase the risk of mortality. Although hypothyroidism is known to be a cause of hyponatremia, it is rare that hyponatremia occurs in relation to hypothyroidism induced by thyroid hormone withdrawal in patients with differentiated thyroid cancer. We report a case of a 76-year-old woman with papillary thyroid carcinoma presenting with severe hyponatremia related to hypothyroidism induced by thyroid hormone withdrawal for radio-active iodine whole-body scanning, who was treated by thyroid hormone replacement and hydration. Considering that the incidence of differentiated thyroid cancer is rapidly increasing, physicians should be aware that, although uncommon, hyponatremia can occur in patients undergoing radioiodine therapy or diagnostic testing.

BACKGROUND/AIMS: Oxidative stress increases the risk of cardiovascular complications of metabolic syndrome (MetS). This study was conducted to examine the difference in antioxidant capacity according to the presence of MetS, and to characterize the association between antioxidant capacity and MetS-related factors. METHODS: We used the biological antioxidant potential (BAP) test to estimate antioxidant capacity. The BAP test has recently been used as an indicator of antioxidant capacity. We measured BAP levels in 45 patients with MetS (mean age, 44.6 +/- 1.1 years) and 47 age- and sex-matched controls (mean age, 42.7 +/- 1.1 years). To evaluate the association between antioxidant capacity and MetS, adiponectin, high-sensitivity C-reactive protein (hs-CRP), interleukin-6, tumor necrosis factor-alpha, and homeostatic model assessment for insulin resistance (HOMA-IR), linear regression and logistic analyses were performed. RESULTS: The mean BAP of the MetS group (1,937.3 +/- 36.5 micromol/L) was significantly lower than that of the non-MetS group (2,101.7 +/- 29.5 micromol/L). Also, the mean BAP was low in persons having low high density lipoprotein and high triglyceride. Reduced antioxidant capacity was significantly associated with adiponectin, HOMA-IR and hs-CRP after adjusting for age and sex. The odds ratios for MetS with BAP, log adiponectin, log HOMA-IR, and log hs-CRP were 0.63 (95% confidence interval [CI], 0.49 to 0.82), 0.22 (0.10 to 0.51), 14.24 (4.35 to 46.58), and 1.93 (1.36 to 2.75), respectively. CONCLUSIONS: Persons with MetS showed reduced antioxidant capacity. We identified relationships between antioxidant capacity measured by BAP test and MetS, as well as MetS-related factors, such as insulin resistance, hs-CRP, and adiponectin.

BACKGROUND: Diabetic patients are predisposed to foot infections because of vascular insufficiency and peripheral neuropathy. Diabetic foot infection is a common cause of mortality and lower extremity amputations (LEAs) in patients with chronic kidney disease (CKD). We evaluated the risk factors for mortality and LEAs in patients with stage 3 CKD or higher with diabetic foot infections. METHODS: We retrospectively evaluated a cohort of 105 CKD patients with diabetic foot infections between July 1998 and December 2011. We reviewed their demographic characteristics and laboratory parameters to evaluate the risk factors for mortality and amputations at 24 weeks after diagnosis of a diabetic foot infection. RESULTS: The mortality of the 105 enrolled CKD patients was 21% at 24 weeks after the diagnosis of a diabetic foot infection. Cox proportional regression analyses revealed that age 60 years or older [odds ratio (OR) 3.03, 95% confidence interval (CI) = 1.02-9.02, P = 0.047] and initial serum C-reactive protein (CRP) level > or = 3 mg/dL (OR 3.97, 95%CI = 1.17-13.43, P = 0.027) were independent risk factors for mortality at 24 weeks.Twenty-four patients (23%) underwent LEAs. On Cox proportional regression analyses, peripheral vascular disease (OR=4.49,95% CI=1.98-10.17, P=0.01) and cerebrovascular accident (OR 2.42, 95%CI=1.09-5.39, P=0.03) were independently associated with LEAs. CONCLUSION: This study showed that age and serum CRP level, were independent risk factors for mortality at 24 weeks in patients with stage 3-5 CKD with diabetic foot infections. Peripheral vascular disease and cerebrovascular accident were significantly associated with LEAs.

Inferior mesenteric arteriovenous fistula is rare and may be congenital or acquired. Affected patients present with abdominal pain, mass, or manifestations of portal hypertension and bowel ischemia. Until now, inferior mesenteric arteriovenous fistula due to trauma has not been reported. Herein, we report a case of a 53-year-old woman who had inferior mesenteric arteriovenous fistula considered to have originated from remote blunt trauma that was successfully treated by surgical resection of only the arteriovenous fistula without colectomy. To our knowledge, this is the first case of traumatic inferior mesenteric arteriovenous fistula.

Dengue fever is an acute febrile disease caused by the dengue virus. As the numbers of reported patients with dengue fever are increasing, rare complications associated with dengue fever, such as rhabodomyolysis or meningitis, are increasing in Korea. We describe the case of a Korean male presenting with fever, myalgia, nausea, diarrhea and blurred vision, who as a result of serologic test and fundoscopy, was diagnosed with dengue fever complicated by retinitis. He completely recovered with conservative care.
