    Chromogranin A and B in parathyroid tissue of cases of primary hyperparathyroidism: an immunohistochemical study (1991)

    Notes: Summary Routinely processed parathyroid tissues from 26 cases with primary hyperparathyroidism (19 adenomas, 7 multiglandular hyperplasia) and 8 normal human parathyroid glands were investigated with antibodies against chromogranin A and B and parathyroid hormone (PTH). Normal parathyroids were immunohistochemically positive for PTH and chromogranin A but negative for chromogranin B. Hyperplastic glands showed a focal staining for PTH and chromogranin A without correlation of the staining pattern on serial sections. Adenomas were either uniformly positive for both PTH and chromogranin A or showed a staining pattern similar to that seen in hyperplastic glands. Focal chromogranin B positivity (less than 10% of cells) was found in 3 cases (1 hyperplastic gland and 2 cases of parathyroid adenoma with an immunohistochemical staining pattern similar to hyperplastic glands). Our immunohistochemical results may support previously published findings that most parathyroid adenomas are monoclonal neoplasms whereas hyperplastic glands are of polyclonal origin.

    Intestinale Angiodysplasie als Ursache schwerer Dünndarmblutungen — Bericht über vier Fälle (1990)
    Springer

    Notes: Summary Angiodysplasia of the small intestine alone cannot be differentiated histologically from hereditary hemorrhagic telangiectasia (Morbus Rendu-Osler-Weber). Isolated localisation in the small intestine is rare and requires surgery in the event of massive bleeding. Four cases of bleeding from angiodysplasias of the small intestine in patients having undergone surgery at our institution over a ten-year period are presented. In three patients the particular intestine was resected. Two of these patients had an uneventful follow-up of even and ten years, one patient relapsed and was rehospitalized for surgical treatment. The fourth patient, who showed angiodysplasias scattered over the entire small intestine, had no further bleeding over a three-year period after transmural ligations of the lesions found by intraoperative endoscopical diaphany.

    Vascular lesions after percutaneous biopsies of renal allografts (1989)
    Springer
    Transplant international 2 (1989), S. 56-58 
    Details
    ISSN: 1432-2277
    Keywords: Vascular lesions in kidney biopsy ; Arteriovenous fistulas in renal transplantation ; Arteriocaliceal fistulas in renal transplantation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract On the basis of two arteriovenous fistulas, one arteriocaliceal fistula, and the literature concerning these complications, clinical symptoms, diagnostic measures, and therapeutic strategies are discussed. Decreased renal function, severe hypertension, and a bruit over the transplant site —particularly after core biopsy — are said to be indicative of an arteriovenous fistula, while persisting hematuria is seen as evidence of an arteriocaliceal fistula. In both cases, angiographic evaluation is indicated. Therapeutic possibilities include selective angiographic embolization and surgical repair. Large intraparenchymal fistulas may require wedge resection.

    Aneurysma der Vena poplitea als Quelle einer Lungenembolie (1986)

    Description / Table of Contents: Zusammenfassung Eine Patientin mit Pulmonalembolien ausgehend von einem klinisch unauffälligen Aneurysma der Vena poplitea wird beschrieben. Die Bedeutung der Venographie bei der Suche nach der Emboliequelle wird unterstrichen und mit anderen Untersuchungsmethoden wie Ultrasonographie, Computertomographie oder Plethysmographie verglichen. Im beschriebenen Fall gelang es, das venöse Aneurysma durch Teilresektion chirurgisch auszuschalten. Die bisher in der Literatur bekannten aetiologischen, diagnostischen und therapeutischen Gesichtspunkte werden diskutiert.
    Notes: Summary A case of pulmonary embolism secondary to a clinically unsuspected aneurysm of the popliteal vein is presented. The importance of venography in establishing the source of pulmonary emboli is stressed in comparison to other diagnostic investigations such as ultrasonography, computed tomography or pletysmography. The aneurysm was suitable for local venous reconstruction. Previously reported cases are reviewed, etiology, diagnosis and treatment of this uncommon condition are discussed.
