Baclofenintoxikation bei chronischer Hämodialyse und Nierentransplantation
2008
Fourteen days after renal transplantation, at first gave with good transplant function, a 36-year-old woman developed neurogenic dysfunction of bladder emptying. This was treated with baclofen, 5 mg three times daily by mouth. Between the 7th and 10th treatment day she progressively developed an organic psychotic syndrome and increasing respiratory paralysis after the onset of renal failure, associated with rejection of the transplanted kidney which required dialysis. Plasma concentration of baclofen was 565 ng/ml (therapeutic range 80-400 ng/ml). After discontinuing the drug and renewed haemodialysis the baclofen level rapidly fell and the symptoms receded. In a second case, a 57-year-old …
A case of sjögren's syndrome with severe anemia due to myelitis
1986
An unusual case of Sjögren's syndrome presenting with severe anemia as the predominant clinical feature is described. Histological examination of a bone marrow biopsy specimen demonstrated that the patient's anemia was caused by myelitis and vasculitis of the small intraosseous vessels. Our report might stimulate a more thorough investigation of bone marrow in patients with connective tissue diseases and anemia.
Proliferation of gastrointestinal carcinoma cells by T lymphocyte factors interleukin-3 and granulocyte-macrophage colony-stimulating factor
1991
Hematopoietic growth factors have been well characterized by cDNA cloning in recent years. In order to determine the influence of rhGM-CSF and rhIL-3 on epithelial cells of the gastrointestinal tract, their influence on in vitro cultured gastric and pancreas cancer cells was determined. A more than two-fold enhancement of proliferation was observed by IL-3 and GM-CSF in Mz-Sto-1 gastric and 818-4 pancreas carcinoma cells, applying a sensitive microculture system which allows precise quantification. The highest growth rates were obtained adding 1-10 ng/ml of the growth factors, but even picogram amounts were effective. Expression of mRNA for GM-CSF and IL-3 remained undetectable in the cell …
Demonstration and partial characterization of an intermediate HBcAG (Dane particle) population.
1981
Abstract Hepatitis-B core antigen (HBcAg) was released from Dane particles previously separated from anti-HBc by repeated pelleting through sucrose gradients separated into three HBcAg populations when analysed by cesium chloride density gradient centrifugation. Heavy HBcAg particles banded at a density of 1.355 gm/ml, intermediate HBcAg particles at a density of 1.33 gm/ml, and light mediate HBcAg particles at a density of 1.30 gm/ml. Like heavy HBcAg particles, intermediate HBcAg particles contained DNA polymerase activity, but the ratio of HBcAg to DNA polymerase activity was significantly different in both populations. Intermediate HBcAg particles could not be separated from heavy HBcAg…
Multiple osteoartikuläre Komplikationen (dialyse-assoziierte Spondarthropathie) und Karpaltunnelsyndrom bei chronischer Hämodialyse
2008
Abstract During a nine-year treatment by haemodialysis for renal failure a now 57-year-old woman developed multiple complications of the skeletal system. Acute calcific periarthritis of the right shoulder became manifest one year after the start of the haemodialysis, followed the next years by progressive arthropathy with subchondral amyloid cysts of both shoulders, effusions in the knee-joint and destructive spondylarthropathy of the middle vertebrae. Carpal-tunnel syndrome also occurred, caused by a beta 2-microglobulin amyloidosis (beta 2-microglobulin concentration in serum 42.6 ng/l) and an aluminium osteopathy. These multiple complications, observed here in one patient, are each of th…
Coexpression of extracellular matrix glycoproteins undulin and tenascin in human autosomal dominant polycystic kidney disease.
1993
Autosomal dominant polycystic kidney disease (ADPKD) is the most common entity of cystic diseases of the kidney leading to end-stage renal insufficiency. Changes in extracellular matrix (ECM) are regarded to be an important pathogenic factor connected with the genes assumed to be responsible for human ADPKD. In order to assess the biological significance of altered expression and deposition of ECM glycoproteins for human ADPKD at molecular levels fresh-frozen tissue from ADPKD kidneys, fetal kidneys and normal adult kidneys were comparatively tested by immunohistochemistry for the presence of multifunctional ECM glycoproteins undulin, tenascin and fibronectin, interstitial collagen types I,…
Reversible Myelofibrose bei angioimmunoblastischer Lymphadenopathie
2008
Ankle oedema and abdominal swelling suddenly developed in a 55-year-old woman who also had lymphadenopathy in the neck, axillae and groin. Ultrasonography demonstrated hepatosplenomegaly, ascites and pleural effusions. Histological examination of some lymph-nodes from the axilla and groin revealed angioimmunoblastic lymphadenopathy (low-malignant peripheral T cell lymphoma). Bone-marrow biopsy was undertaken because of a normocytic anaemia (haemoglobin 4.9 g/dl) requiring blood transfusion, thrombocytopenia (5000/microliters) and monoclonal IgG gammopathy. This showed lymphoma-associated secondary myelofibrosis. Treatment with prednisone (2 mg/kg daily for 8 weeks) and vincristine (1 mg/m2 …
Extrakorporale Stoßwellenlithotripsie von Gallenblasensteinen: Wie viele Patienten sind geeignet?
2008
The proportion of patients with gallbladder stones suitable for extracorporeal shockwave lithotripsy (ESWL) was analysed prospectively in 200 patients aged 17-76 years (62 males, 138 females) with symptomatic cholecystolithiasis. Criteria for inclusion were clinical symptoms, solitary stones (diameter 10-30 mm) or up to three stones with comparable total volume, contractile gallbladder, no calcification of stones, normal biliary tract anatomy. To check these criteria a step-by-step diagnostic procedure was instituted which consisted of history, ultrasonography with contractility test, abdominal X-ray film, computed tomography measurement of stone density, and endoscopic retrograde cholangio…
Detection of hepatitis B virus markers in sera of asymptomatic hepatitis B surface antigen carriers with special emphasis to pre-S-encoded proteins.
1987
Sera of asymptomatic hepatitis B surface antigen (HBsAg) carriers were analyzed for the presence of pre-S-encoded proteins. Four individuals with biopsy-proven chronic hepatitis uniformly expressed pre-S1- and pre-S2-encoded proteins. Individuals who had histologically normal or largely normal livers were heterogeneous with respect to expression of pre-S-encoded proteins. This heterogeneous expression of pre-S-encoded proteins occurred most likely due to difference in serum HBsAg concentration. Alternatively differences in pre-S gene expression need to be considered. Clinically the study indicates that expression of pre-S domains in serum is unrelated to viremia or chronic liver disease.
Detection of the DCC gene product in normal and malignant colorectal tissues and its relation to a codon 201 mutation.
1998
Protein expression of the putative tumour-suppressor gene DCC on chromosome 18q was evaluated in a panel of 16 matched colorectal cancer and normal colonic tissue samples together with DCC mRNA expression and allelic deletions (loss of heterozygosity, LOH). Determined by a polymerase chain reaction (PCR)-LOH assay, 12 of the 16 (75%) cases were informative with LOH occurring in 2 of the 12 cases. For DCC mRNA, transcripts could be detected in all analysed normal tissues (eight out of eight) by RT-PCR, whereas 6 of the 15 tumours were negative. DCC protein expression, investigated by immunohistochemistry using the monoclonal antibody 15041 A directed against the intracellular domain, was hom…
Extrasystolie während extrakorporaler biliärer Stoßwellenlithotripsie: Inzidenz und klinische Bedeutung*
2008
Incidence and clinical significance of cardiac side effects of extracorporeal shock-wave lithotripsy (ESWL) were prospectively analysed for 85 patients (26 men, 59 women; mean age 44 [17-81] years) with cholecystolithiasis (n = 70) or choledocholithiasis (n = 15). 24-hour ECG monitoring was undertaken on the day of treatment. Additionally, during ESWL cardiac rhythm and blood pressure were monitored. ESWL was performed with an electromagnetic lithotriptor under light anaesthesia with intravenous diazepam (10 mg) and pethidine (75-100 mg). There were no superventricular premature systoles in any of the patients during treatment. In 15 patients with occasional ventricular premature systoles (…
