BACKGROUND The Van Nuys Prognostic Index (VNPI) purports to predict the risk of ipsilateral breast tumor recurrence (IBTR) after excision of ductal carcinoma in situ (DCIS). It is a simple scoring scheme based on a retrospective evaluation of data from a single group of investigators. Various versions of VNPI have been proposed using clinical and pathologic(More)
Gastrointestinal cryptococcosis is extremely rare, especially in patients with no involvement of the central nervous system. We describe a 63-yr-old man undergoing prednisone therapy for chronic hepatitis and cirrhosis who presented with peritonitis, colitis, and skin lesions. Pathological studies revealed necrosis and numerous cryptococcal organisms in the(More)
We report two patients who underwent orbital exploration yielding the diagnosis of sclerosing orbital pseudotumor. The presenting symptoms were exophthalmos, visual loss, abnormal ocular mobility, and ocular pain. Computed tomographic (CT) scans showed masses in the orbital apex. Steroids were ineffective. Orbital pseudotumor is a heterogeneous diagnostic(More)
To confirm the accuracy of guided percutaneous aspiration (GPA) in distinguishing sterile from infected pancreatic necrosis, we have performed Brown-Brenn tissue Gram stains on pancreatic and peripancreatic necrotic tissue removed operatively in 15 patients. In eight patients judged to have sterile necrosis on the basis of negative cultures of pancreatic(More)
tant to exclude factors other than the amoxicillinclavulanate for the etiology of the cholestasis in this case. This, in fact, happens to be the only case reported in a pediatric age group (1-6). In our larger series, the mean age of the patients was 5 I. 1 years (range 33-80 years) (2). Considering the extensive use of this drug in pediatric patients,(More)
Axillobifemoral bypass is a well-established surgical procedure performed in conditions that preclude direct arterial reconstruction due to aortic sepsis, aortoenteric fistula, or other hostile abdominal pathology or prohibitive surgical risk. The choice of prosthetic graft used is either knitted Dacron(R) or polytetrafluoroethylene, with equally good(More)
Lymphogranuloma venereum (LGV) usually manifests as an inguinal syndrome, but it can also cause an anorectal syndrome that is difficult to diagnose because of its similarity to other disorders, the lack of easily available specific laboratory tests, and an assumption that it occurs only in women or homosexual men. LGV proctitis is often mild, but chronic(More)
Plasmacytoma, which is a localized malignant plasma cell tumor, occurs rarely and is found mostly in the upper airways of older patients. Two urethral plasmacytomas have been reported, 1 of which was a primary lesion. We describe a primary plasmacytoma of the urethra in a 23-year-old woman who had been exposed to diethylstilbestrol in utero. The patient(More)
