    Notes: Abstract Background. Pseudometastatic lesions of the liver may be discovered incidentally in children previously treated for malignant tumour.¶Objective. To describe the radiological pattern of these lesions and to analyse their pathogenesis.¶Materials and methods. Nine children, 2–12 years' old at the time of diagnosis, are described in this retrospective multicentre report. The primary tumours were: nephroblastoma (n = 2), neuroblastoma (n = 2), Ewing's tumour/PNET (n = 2), non-Hodgkin's lymphoma (n = 1), and osteosarcoma (n = 2), treated by surgery (8/9), chemotherapy (9/9), intensive chemotherapy and bone-marrow transplantation (5/9), and radiotherapy (7/9). Three children suffered veno-occlusive disease (VOD) during treatment. The hepatic assessment was performed by sonography (8/9), Doppler (7/9), multiphase spiral CT (8/9) and MRI (7/9).¶Results. Lesions were discovered 15 months to 16 years after completing treatment. CT was the most sensitive modality for diagnosis. Lesions were multiple in eight cases, measured 2–50 mm, and appeared hypervascular on the arterial phase of CT and/or MRI in every case. Metastases were excluded on the basis of histological verification (n = 2) and clinical and radiological follow-up.¶Conclusion. Pseudometastatic hypervascular hepatic nodules can appear after treatment of a malignant tumour in children. The hypothesis of benign regenerative lesions secondary to treatment and/or VOD is considered.

    Notes: Abstract Observation with an improved signal-to-noise ratio of the hyperfine resonance pattern of199Hg+ stored in a radiofrequency trap is reported. A frequency control loop which locks the frequency of a 5MHz quartz crystal oscillator to the hyperfine transition of stored mercury ions, close to 40.5 GHz, is described. In this system, pulses delivered by the photomultiplier are processed digitally. Optimal conditions for the interrogation of the hyperfine transition are specified. A fractional frequency stability σy(τ)=3.6×10−11τ−1/2 for 10s〈τ〈3500s has been obtained. This frequency stability is comparble to that of commercially available cesium beam frequency standards. Prospect for improvement by a factor of at least 10 are discussed.

    The various phenotypes in Xp deletion. Observations in eleven patients (1981)

    Notes: Summary Eleven Xp-deletion patients with various phenotypes ranging from normal to the Turner syndrome are reported. To explain the phenotypy-karyotype correlation the hypothesis is brought forward that (an) autosomal gene(s) may play a role in the pathogenesis of the Turner syndrome.

    Cytogenetic survey in couples with recurrent fetal wastage (1984)
    Springer
    Human genetics 〈Berlin〉 65 (1984), S. 336-354 
    Details
    ISSN: 1432-1203
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Cytogenetic studies have been performed in 1068 couples with antecedent fetal wastage, i.e., at least two spontaneous first trimester abortions or one spontaneous first trimester abortion and one late fetal death, particularly with multiple congenital malformations. Three major types: 33 reciprocal translocations (3.09%), 20 Robertsonian translocations (1.87%) and six other chromosomal abnormalities (0.56%) were found, bringing the total number of chromosomal abnormalities to 59 (5.5%) in 1068 couples under investigation. In contrast to couples with reciprocal translocations, a high excess of female over male carriers was found in the group of Robertsonian translocations. In the evaluation of chromosomal polymorphisms, only variants with particularly large paracentromeric constitutive heterochromatin blocks were taken into account, and their low frequency in the present study is therefore not comparable with that in a general population. The impact of further extensive familial investigation on genetic counseling and the follow-up of prenatal diagnosis are discussed.

    Time course of oxidative stress after major burns (2000)

    ISSN: 1432-1238
    Keywords: Keywords Burns ; Oxidative stress ; Antioxidants ; Vitamin C ; Trace elements ; Carotenoids

    Notes: Abstract Objective: To evaluate oxidative stress resulting from major burns in humans.¶Design: Prospective clinical study with control group.¶Setting: Mechanically ventilated adult patients admitted with more than 30 % total burn surface area.¶Patients and participants: 20 patients with a mean body surface burned area of 54 %.¶Measurements and results: The oxidative stress evaluation was based on measurements of trace elements, vitamins, antioxidant enzymatic activity and end-products of lipid peroxidation. During the first 5 days after injury burn patients exhibit a decrease in selenium and antioxidant vitamins (C, β-carotene, lycopene) and an increase in lipid peroxidation products (TBARS).¶Conclusion: Our results suggest that major burn is associated with oxidative stress during the 5 days after the initial injury, as demonstrated by a simultaneous decrease in antioxidant vitamins and a large increase in TBARS.

    Iatrogenic dissection of the portal vein during TIPS procedure (2000)

    Notes: Abstract. Dissection of the portal vein is a rare entity which has been rarely described during transjugular intrahepatic portosystemic shunt (TIPS) procedure. We report three cases of dissection during this procedure and their complications. One dissection was immediately treated with coaxial stents. The two others were complicated either by a thrombus or by a false aneurysm. In the first case a second parallel stent was used to treat this complication. The patient with the portal vein false aneurysm was transplanted 4 days after this diagnosis. Portal vein dissection in TIPS procedure appeared to be less rare than has been reported and must be considered as a potential cause of TIPS dysfunction.

    Radiological follow-up of inverted papilloma (2000)

    Notes: Abstract. The aim of this study was to describe cross-sectional imaging features of recurrent papilloma of the nasal fossa and paranasal sinuses and to evaluate the role of MR and CT in the postoperative follow-up of this lesion. Magnetic resonance imaging and CT of ten patients who presented recurrence of inverted papilloma were reviewed and correlated to initial imaging, endoscopy, and surgical reports. Imaging patterns of recurrent inverted papilloma are identical to those of initial tumors and recurrence location is closely related to the site of the former lesion. Magnetic resonance is more efficient than CT for the diagnosis and evaluation of extensions. Magnetic resonance supplies the deficiencies of endoscopy in case of extensions to the frontal sinus or the lateral recess of the antrum, especially if mucosal hyperplasia or sinusitis is associated. Magnetic resonance imaging is the first imaging modality to perform in the follow-up after removal of inverted papilloma.
