Fumonisins Veratox. A new rapid quantitative ELISA for determination of fumonisin in food and feed.

Polyclonal antibodies against fumonisin B1 were produced by immunizing sheep with fumonisin B1-keyhole limpet hemocyanin as an immunogen. A quantitative competitive enzyme-linked immunosorbent assay was developed whereby free fumonisins or sample extract containing fumonisins and enzyme-labelled fumonisin competed for binding to the solid phase-bound antibodies. The color intensity of wells, formed by substrate reaction with the enzyme, was inversely related to FB1 concentration. Detection limits for the assay were 0.1 ng/mL fumonisin B1 and concentrations of fumonisins B1, B2, and B3 required for 50% binding inhibition were 5.5, 23 and 18 ng/mL, respectively. For food and feed analyses, samples were extracted with 70% methanol and dilution of the extracts were used directly for ELISA. ELISA results were compared to HPLC analyses by a reference laboratory and the correlation (r value) between ELISA and HPLC was 0.967. The assay may be used to quantitate fumonisins in food and feed within 30 minutes.

Posterior leg sepsis associated with pyogenic arthritis of the knee. A report of two cases.

The association of posterior leg sepsis with pyogenic arthritis of the knee is rare, but nevertheless the diagnosis should be kept in mind. Calf swelling and tenderness with apparent antibiotic resistance in pyogenic arthritis of the knee are the major signs of the diagnosis. Ultrasound, computerized axial tomography, or aspiration of the posterior compartment may show fluid in the posterior compartment. Clinical examination is the most dependable method of diagnosis. Treatment consists of adequate surgical drainage of the posterior compartment and appropriate antibiotic therapy.

Percutaneous embolization of bony pelvic neoplasms with tissue adhesive.

Eight patients with tumors of the bony pelvis underwent embolization with isobutyl-2-cyanoacrylate (IBCA). Five patients had primary bone tumors, of which 2 were malignant and 3 were benign; 3 patients had metastases to the bony pelvis from the thyroid gland, kidney, and femur, respectively. Embolization was performed to minimize blood loss during resection of a giant-cell tumor in one patient and insertion of a hip prosthesis in another who had metastatic renal carcinoma. It was also done prior to scheduled surgery in one of the patients with aneurysmal bone cyst, but healing was sufficient to cancel the operation; in the other patient, embolization was the only therapy. Palliative embolization was performed in 4 patients with malignant tumors after other means failed to control pain or slow progression. IBCA appears to be an efficient means of occluding the vessels feeding selected primary bone tumors and metastases.

Carpal and tarsal osteolysis.

A 19-year-old girl with carpal and tarsal osteolysis has been presented. The clinical course was characterized by normal early growth and motor development followed by the insidious onset in early childhood of a progressive, peripheral joint destruction, especially in the tarsal and carpal bones. The patient's course was complicated by acquired spasticity from platybasia, scoliosis, generalized muscle weakness, mild growth failure and corneal clouding.

Pelvic osteotomy for bladder exstrophy.

Twenty-five patients with bladder exstrophy underwent pelvic osteotomy at or before initial bladder closure and anterior abdominal repair. Ten patients underwent bilateral iliac osteotomies before 1977. An alternative procedure consisting of bilateral superior pubic ramotomies has been used in 15 patients since 1977. In all patients, successful tension-free closure of the abdomen was achieved. Long-term follow-up of these two groups of patients shows no difference in the degree of pubic diastasis, which was asymptomatic. Posterior iliac osteotomy requires two additional incisions, longer operative time, and postoperative immobilization. We therefore recommend bilateral superior pubic ramotomy as an alternative procedure in initial reconstruction of the anterior abdomen in patients with bladder exstrophy.
