Black oesophagus.

Acute oesophageal necrosis, also known as 'Black Oesophagus', is a rare endoscopic finding since its first description by Goldenberg in 1990. In endoscopic studies, the frequency ranged from 0.01% to 0.2%. The aetiology is undefined and is probably multifactorial. A 62-year-old woman, with chronic alcoholism, was admitted to the internal medicine department for dehydration and marked malnutrition problems. Melaena was detected, and oesophagogastroduodenoscopy showed black mucosa of the lower two-thirds of the oesophagus and candidiasis. The patient gradually recovered after conservative treatments (intravenous proton pump inhibitor and total parental nutrition) and fluconazole. Oesophagus stricture was developed after 1 month, and balloon dilatation was performed successfully.

Acute hepatitis associated with the use of levofloxacin.

BACKGROUND: Levofloxacin is a fluoroquinolone used globally to treat respiratory, skin, and genitourinary tract infections. It is generally well tolerated and there is a very low risk for liver injury in patients taking this antibiotic. OBJECTIVE: We report an acute case of hepatitis following treatment with levofloxacin for pneumonia. CASE SUMMARY: A 77-year-old white male (height, 162 cm; weight, 58 kg) with chronic bronchitis presented to the emergency department of the Hospital Curry Cabral, Lisbon, Portugal, with respiratory difficulty and productive cough. The patient had a history of chronic bronchitis, arterial hypertension, hypercholesterolemia, and benign prostatic hyperplasia, and was being treated with salmeterol 50 µg plus fluticasone 250 µg BID, and amlodipine 5 mg, simvastatin 20 mg, alfuzosin 10 mg, and finasteride 5 mg once daily. Initially, the patient refused admission and was sent home, medicated with levofloxacin 500 mg once daily (single dose) for pneumonia and acetaminophen 1 g (as needed, maximum TID) if axillary temperature exceeded 38.0°C (100.4°F). Three days later, the patient returned for a follow-up visit, and despite clinical and radiologic improvement, blood tests revealed a slight aggravation of anemia. On the seventh day of treatment with levofloxacin, the patient showed an elevation of transaminases. The temporal relation between the use of levofloxacin and the liver injury, the exclusion of other causes of hepatitis, and a compatible liver biopsy (conducted 14 days after identification of hepatitis) was consistent with the diagnosis of levofloxacin-associated hepatotoxicity. Levofloxacin treatment was stopped and the patient made a full recovery. The Naranjo Adverse Drug Reaction Probability Scale score for this association was "probable" (score 7) and the Roussel Uclaf Causality Assessment Method Scale score was "highly probable" (score 9). Unlike the 5 reported cases in the literature, this is the only case in which both a liver biopsy was performed in the course of the disease and the patient survived. CONCLUSION: The acute hepatitis observed in this elderly patient was probably associated with the administration of levofloxacin.

Blood loss anemia due to adenocarcinoma of the jejunum: case report and review of the literature.

BACKGROUND: Small bowel tumors are rare, accounting for only 3-6% of gastrointestinal neoplasms, 1-2% of these being malignant. They must be considered whenever a patient presents with gastrointestinal bleeding, with normal upper gastrointestinal endoscopy and colonoscopy. CASE PRESENTATION: We report a case of jejunal adenocarcinoma presenting as a blood loss anemia in a 65 year-old male, doing a brief review on the subject. CONCLUSION: Our case intends to highlight the fact that small bowel tumours are rare and frequently present to the Internist as non-specific clinical symptoms.

Mycoplasma pneumoniae-associated mucositis with minimal skin manifestations.

Mycoplasma pneumoniae-associated mucositis is a rarely described complication of M. pneumoniae infection presenting with ocular, oral, and genital involvement but without the typical skin lesions seen in Stevens-Johnson syndrome. A 27-year-old man with a past history of asthma presented at the emergency room with a 1-week history of cough (initially non-productive but subsequently associated with non-bloody mucopurulent sputum), fever, myalgias, headache, and progressive dyspnea. Two days before admission he had commenced amoxicillin/clavulanic acid with no improvement. The patient reported bilateral conjunctival injection and hemorrhagic ulcers on the lips commencing the day prior to admission. Physical examination revealed fever (39 degrees C), bilateral exudative conjunctivitis, painful hemorrhagic ulcers on the lips, tongue, and oral mucosa, small scrotal erosions, erythema of the penile meatus, and small erythematous bullae on the dorsum of each hand; subsequently, the patient developed bullae at the venipuncture site on his right arm. Laboratory tests revealed positive IgM serology for M. pneumoniae, with titer elevation. The patient was successfully treated with levofloxacin and prednisolone. Our case appears to be the first adult patient described with M. pneumoniae-associated mucositis, which has previously been reported only in pediatric patients. This is also the first reported instance of a case of M. pneumoniae-associated mucositis treated with levofloxacin and prednisolone. M. pneumoniae infection should be considered in all cases of mucositis, and treatment of this condition with levofloxacin and prednisolone seems to be effective.
