Sonographically guided thrombin injection for the treatment of femoral artery pseudoaneurysm.

The formation of pseudoaneurysm in the femoral artery after cardiac catheterization is a well-recognized complication occurring in 1%-4% of cases. It is traditionally managed surgically and has a high morbidity. Prolonged ultrasound-guided compression of the neck of the pseudoaneurysm, and ultrasound-guided injection of thrombin into the aneurysm are newer modalities of treatment especially for small aneurysms. We describe the case of a giant pseudoaneurysm of the right femoral artery, post-arteriography, which was successfully managed with ultrasonographically guided percutaneous thrombin injection.

Delayed cardiac metastasis from phyllodes breast tumor presenting as cardiogenic shock.

Malignant metastases to the heart and pericardium, which occur far more often than do primary cardiac neoplasms, typically lead to fatal outcomes. The phyllodes tumor is a rare, predominantly benign fibroepithelial breast neoplasm with variable malignancy potential. Herein, we describe the case of a 35-year-old woman who, 3 years after undergoing a simple mastectomy for a rapidly enlarging breast neoplasm, presented with cardiogenic shock and was found to have a large right ventricular tumor that obstructed the right ventricular outflow tract. Despite successful resection of the ventricular mass and a right atrial mass of organized thrombus, the patient died 8 days postoperatively of multiorgan failure due to severe right ventricular dysfunction. Histopathologic analysis determined that the right ventricular mass was a malignant, metastatic phyllodes tumor. To our knowledge, this is only the 2nd reported case of a phyllodes tumor that metastasized to the heart and presented as an intracavitary mass with cardiogenic shock. In addition to discussing our patient's case, we review the pertinent medical literature.

Restrictive physiology in tetralogy of Fallot: exercise and arrhythmogenesis.

The effect of right ventricular restrictive physiology on exercise capacity and arrhythmogenesis after correction of tetralogy of Fallot was assessed in 80 patients aged 7.9 +/- 3.6 years. Right ventricular restrictive physiology was defined as the presence of an A wave across the pulmonary artery on 2-dimensional echocardiography. At the 6 month follow-up, 52 patients had restrictive physiology (group 1). A transannular patch was used in 36 patients in group 1 (62%) and in 19 (86%) of the 28 patients without restrictive physiology (group 2). Maximum heart rate attained (69% vs. 77%), maximum predicted heart rate (211 +/- 12.6 vs. 226 +/- 24.2 beats x min(-1)), and metabolic equivalents (7.6 +/- 3.2 vs. 8.1 +/- 2.6) were higher in group 2, but not significantly. The chronotropic index was similar in both groups. In group 1, 14% of patients presented with ventricular premature complexes at 6 months. No effect on exercise capacity and arrhythmogenesis could be attributed to restrictive physiology, but both groups had chronotropic incompetence compared to normal children.

Onychomycosis in central India: a clinicoetiologic correlation.

BACKGROUND: Onychomycosis is mainly caused by dermatophytes, but yeasts and nondermatophyte molds have also been implicated, giving rise to diverse clinical presentations. The etiological agents of the disease may show geographic variation. The aim of the present study was to isolate the causative pathogens and to determine the various clinical patterns of onychomycosis in central India. METHODS: The study population comprised 90 patients with onychomycosis. Nail samples were collected for direct microscopic examination and culture. Clinical patterns were noted and correlated with causative pathogens. RESULTS: The male : female ratio was 3:1 and the mean age was 29.40 +/- 13.61 years. Fingernails were involved in 60%, toenails in 26.67% and both fingernails and toenails in 13.34% of the 90 patients. The clinical types noted were distolateral subungual onychomycosis (64.44%), total dystrophic onychomycosis (17.78%), proximal subungual onychomycosis with paronychia (12.2%), proximal subungual onychomycosis without paronychia (4.44%) and superficial white onychomycosis (1.11%). Dermatophytes were the most common pathogens isolated, being found in 24 patients (26.36%) [Tricophyton rubrum (23.07%), Tricophyton verrucosum (2.22%) and Epidermophyton floccosum (1.11%)], followed by Candida albicans, which was found in 22 patients (24.27%). Thirty-six (39.58%) nondermatophyte molds were isolated from 29 patients. Of these 29 cases, six were associated with Tricophyton rubrum, which was considered the primary pathogen. CONCLUSIONS: Distolateral subungual onychomycosis was the most common clinical presentation; however, total dystrophic onychomycosis and proximal subungual onychomycosis were not uncommon in this part of India. Tricophyton rubrum and Candida albicans were the major pathogens. The clinicoetiologic correlation revealed that a single pathogen could give rise to more than one clinical type.
