Following the rapid withdrawal of the catheter, the lungs remained fully expanded in five cases. In two cases, the tissue adhesive had to be applied interpleurally a second time, and in one case on three occasions at one-day intervals. In none of these cases did any major complications occur.

She did not respond within 3 weeks, and multidrug-resistant (MDR) TB was suspected. Direct plating on susceptibility media was performed immediately. Treatment was initiated with IV capreomycin, levofloxacin, para-aminosalicylic acid, pyrazinamide, cycloserine, and high-dose vitamin B(6) at 26 weeks' gestation. The patient delivered vaginally at week 35. The newborn was not infected. Following delivery, ethionamide was added as a sixth drug, and levofloxacin was replaced with moxifloxacin. The patient's sputum became smear-negative and culture-negative for TB. All reported cases of MDR-TB during pregnancy are reviewed.

The details of two patients from the authors' institution and 15 published cases are reviewed in terms of their risk factors, clinical findings and outcomes. Only two of eight patients with paravalvular leakage or abscess--the most serious local complications--survived, both with surgery. It appears that NTS bacteremia in patients with prosthetic valves and concomitant risk factors should be treated early with high-dose antimicrobials for up to six weeks in order to minimize the risk of endocarditis.

The type I defect (2) results in a direct shunt through a portion of the membranous septum, while a type II (indirect) defect occurs if the membranous septal defect lies below the attachment of the septal leaflet of the tricuspid valve. The shunt is directed towards the right atrium through a cleft or perforations of the septal leaflet. Acquired Gerbode defects have been identified in endocarditis, after mitral or aortic valve surgery, or may be post-traumatic. The case is presented of a 69-year-old woman with a postoperative Gerbode defect in association with aortic prosthetic endocarditis caused by non-typhoid Salmonella.

Although clopidogrel is generally well tolerated, with rash, indigestion, vomiting, diarrhea, and bleeding being the most common adverse effects, rare but serious complications may occur. We describe a 78-year-old woman who underwent percutaneous coronary intervention with drug-eluting stents; clopidogrel and aspirin were started as antiplatelet therapy. Three weeks later, the patient developed mixed hepatocellular and cholestatic liver injury. Clopidogrel was discontinued, and her liver profile results began to improve. Her diagnostic work-up included screening for hepatitis, infectious mononucleosis, and rheumatologic diseases, as well as ultrasonography, magnetic resonance imaging, and endoscopic retrograde cholangiopancreaticography; all results were normal. On day 5 of hospitalization, because of the patient' s risk for thrombosis secondary to the drug-eluting stents, clopidogrel was reintroduced; her liver enzyme levels increased. In the absence of any biliary obstruction or other obvious causes of hepatic injury, drug-induced hepatocellular injury and cholestatic jaundice were suspected, and clopidogrel was again discontinued. The patient' s liver function tests gradually improved 3 days later and showed marked improvement at her 2-week follow-up visit after discharge. Use of the Maria and Victorino scale for diagnosis of drug-induced hepatotoxicity indicated a probable (score of 14) relationship between clopidogrel and mixed hepatocellular injury and cholestatic jaundice in this patient. Although routine liver function testing is not recommended in patients who receive clopidogrel, having a high index of clinical suspicion, drug rechallenge, and excluding other obvious causes are required to establish the diagnosis of a rare drug complication such as clopidogrel-induced hepatic injury.
