A 71-year-old male with recurrent colon cancer was admitted to our hospital with obstructive jaundice. Virchow's node metastasis was palpable in his neck. The enlarged intraabdominal lymphnodes due to recurrence and liver metastasis were demonstrated on computed tomography. Bile duct obstruction was treated by expandable metallic biliary endoprosthesis. 5'-DFUR (5'-deoxy-5-fluorouridine) was administered orally at 600 mg daily. Virchow's node metastasis completely disappeared by 46 days after administration of 5'-DFUR. The enlarged intraabdominal lymphnodes and liver metastasis disappeared on computed tomography. No significant side effects from 5'-DFUR were encountered for 18 months. 5'-DFUR appears to be a useful and safe treatment for recurrent colon cancer.

A 71-year-old man with chronic atrial fibrillation was treated with aspirin because of a right cerebral infarction. Oral anticoagulation was not initiated because of a secondary hemorrhagic transformation. Six years later after a left cerebral transient ischemic attack aspirin was replaced by ticlopidine. Two weeks after starting ticlopidine he experienced abdominal cramps and diarrhea. Also dark urine and gray-colored stools were noticed, so that the patient stopped taking ticlopidine. 40 days after starting ticlopidine he was admitted to our hospital because of cholestatic jaundice. Serum alkaline phosphatase (305 U/l) and gamma GT (143 U/l) were elevated, the total bilirubin was 18.6 mg/dl at peak. GOT and GPT were 2.7 fold increased. After exclusion of a viral infection and autoimmune disease liver biopsy was performed, which showed a centroacinar cholestasis compatible with a drug-induced liver damage. 79 days after discontinuation of the drug laboratory signs of cholestasis had disappeared. In patients in whom long-term therapy with ticlopidine is indicated regularly laboratory tests and clinical examinations should be done to recognize infrequent side effects such as the cholestatic hepatitis in time.

Ectopic ACTH secretion represents 8-18% of the cases of endogenous hypercortisolism. Pheochromocytomas correspond to 2-25% of the cases and surgery is the indicated treatment. We describe a case of ACTH-secreting pheochromocytoma treated with percutaneous ethanol injection (PEI) guided by computed tomography (CT). A 71-yr-old man presented with diabetes, severe hypokalemia, weight loss, muscle weakness, and hypertension. Hormonal evaluation revealed elevated levels of urinary cortisol, ACTH, catecholamines, and urinary metanephrines. There was no cortisol or ACTH response to desmopressin stimulation test. Magnetic resonance revealed bilateral adrenal nodules, larger on the left side. The suspected diagnosis was ectopic ACTH syndrome caused by pheochromocytoma. Ketoconazole treatment resulted in reduction of urinary cortisol levels but was followed by severe cholestasis and hepatic dysfunction, preventing surgery; it was substituted by octreotide with reduction of ACTH and cortisol levels, but without improvement of cholestasis. The patient presented cachexia and developed multiple pulmonary abscesses that also prevented surgical treatment, thus he was treated with percutaneous ethanol injection guided by CT of the left adrenal tumor. During the procedure, the patient had an increase in blood pressure controlled by the infusion of sodium nitroprusside followed by hypotension that required infusion of dopamine and volume expansion. Afterwards, he presented hormonal normalization, normal catecholamines levels, and clinical improvement. Histological tissue analysis confirmed pheochromocytoma. We concluded that CT-guided PEI represents an efficient alternative therapy to ectopic ACTH-secreting pheochromocytomas in patients without clinical conditions for surgery.

A 71-year-old female with no history of liver disease or antibiotic allergy developed jaundice with elevated liver enzymes and eosinophilia following treatment with nafcillin for septic arthritis. Further workup demonstrated hepatocellular dysfunction and liver biopsy showed expansion of portal tracts by lymphocytes and eosinophils consistent with a hypersensitivity reaction. Nafcillin and related antibiotics were withdrawn, and her symptoms resolved 3 months later. We searched PubMed using terms of "nafcillin cholestasis" and "nafcillin hepatitis", and a review of the literature showed other reports of nafcillin-induced hepatitis and cholestasis. Avoidance and on occasion the guarded use of glucocorticoids can lead to recovery from the insult. This case report shows that while rare, nafcillin can cause cholestatic hepatitis through a likely eosinophil-mediated hypersensitivity reaction. Further studies are needed to elucidate the mechanism of this reaction.
