    Cystic islet cell tumors: Radiologic findings in three cases (1994)

    Notes: Abstract We report three cases of cystic islet cell tumors, two caused by gastrinomas and the other by an islet cell carcinoma. All three patients underwent computed tomography (CT) and angiography and two also had magnetic resonance (MR) imaging. Several common radiographic findings were present as follows: thickening of the cyst wall and irregularity of the inner surface on postcontrast CT and MR images, neovascularity and a densely staining hypervascular rim on angiography, and moderately increased signal intensity of the cyst content on T1-weighted MR images, which indicated fluid containing blood and/or necrotic tissue. These findings are helpful in defining the nature of these lesions and strongly suggest that cystic islet cell tumor should be included in the differential diagnosis.

    Selective loss of nigral neurons in Pick's disease: a morphometric study (1990)

    Notes: Summary Loss of neurons from the substantia nigra (SN), which is often encountered in Pick's disease, was quantitatively analyzed in 13 cases of Pick's disease and 19 age-matched controls. On sections from the upper and lower portions of the SN, the pigmeted zone (zona compacta) and the non-pigmented zone (zona reticulata) were delineated, and these zones were partitioned into quarters: medial, mid-medial, mid-lateral and lateral. Neuronal loss was fairly severe and more evident in the upper section of the SN (−40%), especially in the midmedial and lateral quarters. In the lower section (neuronal loss:−28%), the medial quarter was most severely affected. Non-pigmented neurons were preserved. Fibrillary gliosis was denser in the zona reticulata, where neuronal loss was minimal. These findings revealed a selective vulnerability of nigral neurons according to their topography and pigmentation and suggests the primary involvement of some neuronal groups (especially the pigmented neurons) of the SN in Pick's disease.

    Measurement of the structure factors of diamond (1990)
    [S.l.] : International Union of Crystallography (IUCr)

    Notes: The absolute values of the structure factors of diamond are determined for nine low-order reflections by measuring the X-ray Pendellösung beats on the wavelength scale. Parallel-sided wafers of synthetic diamond single crystals are used for specimens. The deformation charge density and the Debye-Waller B factor are evaluated from the structure factors. The charge density of pile-up electrons is estimated to be 0.44(17) eÅ-3 at the midpoint between the nearest-neighbour atoms. The density is slightly smaller than that determined by the powder diffraction method. The obtained B factor, 0.142 (9) Å2, is in good agreement with that evaluated to date from neutron diffraction measurements.

    Selective C1q deficiency in a patient with systemic lupus erythematosus (1987)

    Notes: We report a case of systemic lupus erythematosus with selective C1q deficiency. C1q deficiency had been presumed to be a non-hereditary disorder; however, the 10 reported cases in the world literature, and our case, suggest that C1q deficiency could also be an inherited disease.

    Description / Table of Contents: Zusammenfassung Es wurden Berechnungen angestellt über die Auftriebseffekte und die Anlaufströmung um einen plötzlich in Bewegung gesetzten Zylinder konstanter Temperatur. Dabei wird die Methode der angepaßten asymptotischen Expansion angesetzt, um für kleine Zeitschritte asymptotische Lösungen zu erhalten. Für die Reynolds-Zahl wird ein endlicher, aber großer Wert und für die Prandtl-Zahl der Wert l angenommen. Für die Geschwindigkeit und die Temperatur wurden Lösungen dritter Ordnung gefunden. Basierend auf diesen Lösungen wurden die Auftriebseffekte auf die Strömung und den Wärmeübergang im Detail untersucht.
    Notes: Abstract An analytical study is made of the buoyancy effects on initial flow around an impulsively started isothermal circular cylinder. The method of matched asymptotic expansions is used to obtain asymptotic solutions for small time. The Reynolds number is assumed to be finite (but large) and the Prandtl number to be unity. The solutions for the velocity and temperature are obtained to the third order. Based on these solutions, buoyancy effects on flow and heat transfer are investigated in detail.

    Choreoathetoid movements associated with a spleno-renal shunt (1988)

    Notes: Summary A 73-year-old woman without liver cirrhosis developed choreoathetoid movements of the limbs due to portal-systemic encephalopathy. A prominent spleno-renal shunt was demonstrated by non-invasive methods (abdominal computed tomography and sonography) as well as arterial portography. The choreoathetoid movements were improved by a protein-resticted diet and administration of lactulose. A portal systemic shunt should be considered when investigating choreoathetosis, even in patients without liver cirrhosis.

    Vitamin E deficiency in acquired fat malabsorption (1990)
    Springer
    Journal of neurology 237 (1990), S. 103-106

    ISSN: 1432-1459
    Keywords: Vitamin E deficiency ; Fat malabsorption ; Diabetes mellitus ; Chronic pancreatitis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Thirteen patients with adult-onset vitamin E deficiency due to fat malabsorption were investigated clinically and electrophysiologically. These patients had slightly or moderately decreased serum vitamin E (1.7–4.8 μg/ml, normal 〈6.0) or vitamin E/cholesterol ratio (0.21–0.31 mg/g, normal 〈0.35). Only one patient had typical neurological manifestations of vitamin E deficiency, which improved with supplementary vitamin E. The pathological findings in this patient were also compatible with vitamin E deficiency. This patient had poorly controlled diabetes mellitus due to advanced chronic pancreatitis. Reviewing previously reported cases of vitamin E deficiency with diabetes mellitus in chronic pancreatitis, the duration of deficiency until the onset of symptoms was shorter than in those cases without complications. Although adult patients with early, slight deficiency of vitamin E are generally asymptomatic, patients with diabetes mellitus tend to have early neurological symptoms. The vitamin E tolerance test should be used, because even in some patients with vitamin E deficiency due to malabsorption, the deficiency can be overcome by large oral doses of vitamin E.
