Metronidazole-induced encephalopathy in a patient with liver cirrhosis

Encephalopathy is a disorder characterized by altered brain function, which can be attributed to various causes. Encephalopathy associated with metronidazole administration occurs rarely and depends on the cumulative metronidazole dose, and most patients with this condition recover rapidly after discontinuation of therapy. Because metronidazole is metabolized in the liver and can be transported by the cerebrospinal fluid and cross the blood-brain barrier, it may induce encephalopathy even at a low cumulative dose in patients with hepatic dysfunction. We experienced a patient who showed ataxic gait and dysarthric speech after receiving metronidazole for the treatment of hepatic encephalopathy that was not controlled by the administration of lactulose. The patient was diagnosed as metronidazole-induced encephalopathy, and stopping drug administration resulted in a complete recovery from encephalopathy. This case shows that caution should be exercised when administering metronidazole because even a low dose can induce encephalopathy in patients with liver cirrhosis

Acral Metastasis in a Patient with Ampullary Carcinoma

Although Skin Metastasis From A Malignant Tumor Of An Internal Organ Usually Occurs At An Advanced Disease Stage, There Has Been No Prior Report Of A Cutaneous Acral Metastasis From Ampullary Carcinoma To Date. We Report A 71-year Old Male Patient With Cutaneous Metastasis From An Ampullary Adenocarcinoma. The Patient Had A History Of Pylorus Preserving Pancreaticoduodenectomy For Carcinoma Of The Ampulla Of Vater Two Years Prior To Presentation. Physical Examination Revealed Ill-defined, Painful And Hard Erythematous Nodules At The Left Thumb And Distal Phalanx Of The Right Middle Finger. The Computed Tomography Scan Showed Low Density Masses In The Retroperitoneum; The Histological Examination Of A Nodule From The Right Middle Finger Showed A Metastatic Adenocarcinoma. This Case Illustrates That Cutaneous Metastasis From Ampullary Carcinoma Has A Poor Prognosis

Treatment Outcomes of Clevudine versus Lamivudine at Week 48 in Naïve Patients with HBeAg Positive Chronic Hepatitis B

The authors assessed the efficacy and antiviral resistance of 48-week clevudine therapy versus lamivudine in treatment of naïve patients with HBeAg positive chronic hepatitis B. In this retrospective study, a total of 116 HBeAg positive patients, who received 30 mg of clevudine once daily (n=53) or 100 mg of lamivudine once daily (n=63) for 48 weeks, were included. At week 48, clevudine therapy produced a significantly greater mean reductions in serum HBV DNA levels from baseline than lamivudine therapy (-5.2 vs. -4.2 log10IU/mL; P=0.005). Furthermore, a significantly higher proportion of patients on clevudine achieved negative serum HBV DNA by PCR (<13 IU/mL) at week 48 (60.4% vs. 38.1%; P=0.025). The incidence of virologic breakthrough in the clevudine group was significantly lower than in the lamivudine group (9.4% vs. 25.4%; P=0.031). However, rates of alanine aminotransferase normalization and HBeAg loss or seroconversion were similar in the two groups (83.0% vs. 81.0%, 11.3% vs. 11.1%; P=0.813, 1.000, respectively). In conclusion, clevudine is more potent for viral suppression and lower for antiviral resistance at week 48 than lamivudine in treatment of naïve patients with HBeAg positive chronic hepatitis B

Multiple Pyogenic Liver Abscesses Caused by Microperforation of an Idiopathic Cecal Ulcer

Idiopathic cecal ulcer is a rare disease entity of unknown cause diagnosed by ruling out other known causes of cecal ulceration. The most common complication of an idiopathic cecal ulcer is bleeding; perforation, peritonitis, abscess, and stricture formation have been noted. The authors treated a 53-year-old woman who presented with fever and intermittent right upper quadrant abdominal pain. Multiple pyogenic liver abscess and a solitary cecal ulcer were diagnosed by radiologic, endoscopic, and pathologic examination, followed by laparoscopic cecectomy. After extensive study, we concluded that this patient’s liver abscesses were a complication of the idiopathic cecal ulcer. Herein, we report a case of multiple pyogenic liver abscess caused by microperforation of idiopathic cecal ulcer. (Korean J Gastroenterol 2016;67:44-48

Pancreatic Panniculitis in Patients with Chronic Pancreatitis: Case Report and Review of Literature

Pancreatic panniculitis is a rare complication characterized by subcutaneous fat necrosis associated with pancreatic disease. It has been postulated that pancreatic panniculitis is caused by the systemic activity of pancreatic enzymes that lead to microcirculatory disturbances. We report a 41-year-old heavy alcoholic woman with pancreatic panniculitis that coexisted with acute and chronic pancreatitis. She was diagnosed with chronic pancreatitis and alcoholic liver cirrhosis 5 years ago. She presented with multiple, tender, erythematous, subcutaneous nodules with heat sensation on both lower legs. Laboratory evaluation revealed an increase in the serum blood amylase and lipase. Histopathologic findings showed fat necrosis with inflammation around the necrotic subcutaneous fat tissue. The lesions subsided gradually with an improvement of acute pancreatitis

Cerebral and pulmonary embolisms after transcatheter arterial chemoembolization for hepatocellular carcinoma

A cerebral lipiodol embolism is an extremely rare complication of transcatheter arterial chemoembolization for hepatocellular carcinoma. We present a case of cerebral lipiodol embolism that occurred after the third arterial chemoembolization, report the clinical and radiological findings, and review the medical literature

Co-development of autoimmune hepatitis and Sjögren's syndrome triggered by the administration of herbal medicines

Autoimmune hepatitis (AIH) has been reported in association with Sjögren's syndrome (SS). Drug-induced AIH has been rarely reported. A rare case of the co-development of AIH and SS in a 53-year-old woman after the consumption of herbal medicines is described. After admission, the patient complained of dryness in her mouth, and she was subsequently diagnosed with SS, which had not been detected previously. The patient's bilirubin and aminotransferase levels initially decreased following conservative management; however, they later began to progressively increase. A diagnosis of AIH was made based on the scoring system proposed by the International Autoimmune Hepatitis Group. The patient was administered a combination of prednisolone and azathioprine, and the results of follow-up liver-function tests were found to be within the normal range. This is an unusual case of AIH and SS triggered simultaneously by the administration of herbal medicines
