HYPOTHESIS Mental strain measured by heart rate variability differs during laparoscopic and conventional sigmoid resections. DESIGN Prospective randomized study. SETTING University hospital. PARTICIPANTS Two surgeons performed 10 conventional and 10 laparoscopic sigmoid resections, alternating roles as primary surgeon and assistant. The kind of(More)
OBJECTIVES To study the frequency, severity, and long-term outcome of renal injury in Cortinarius orellanus poisoning, to evaluate the association between the ingested amount of C. orellanus and outcome, and to evaluate the effect of N-acetylcysteine and corticosteroid treatment on outcome. METHODS Case series of eight patients. Diagnosis and severity of(More)
Gallium chest scans of 575 patients were analyzed for their clinical usefulness in conjunction with chest radiographs. The series included patients with pulmonary carcinoma, lymphoma, tuberculosis, sarcoidosis, pneumoconiosis, and interstitial fibrosis. Gallum scintigraphy does not aid in the differential diagnosis of pulmonary diseases but is helpful in(More)
Imaging of the chest cage with gallium-67 (67Ga) citrate is relatively easier to perform and interpret than imaging of the abdomen, because normally pulmonary concentration is low after 48 hr and physiologic accumulation in bones and breast can be recognized by its distribution. Modern scintillation detectors, particularly large field cameras with multiple(More)
Twelve patients with the long QT syndrome were studied to determine the usefulness of 123I-metaiodobenzylguanidine (MIBG) single-photon emission tomography (SPECT) at 2 h and 6 h after injection; the results were compared to 10 healthy volunteers (controls). Uptake of MIBG in the left ventricle at 2 h after injection was significantly reduced in patients(More)
For evaluating the clinical significance of thyroglobulin measurements for the follow-up of patients with differentiated thyroid carcinoma, thyroglobulin was determined radioimmunologically during the past 2 years (up to 12 times) in 40 patients after withdrawal of thyroid hormone. Thyroglobulin values were compared with whole-body scintigrams after(More)
Clinical examination is still the most important diagnostic tool and duplex ultrasonography is the imaging method of first choice. Radiological assessment of vascular access for haemodialysis includes preoperative analysis of vessel anatomy and postoperative surveillance for access maturation as well as diagnosis in vascular access insufficiency. Compared(More)
The following parameters were measured in 95 euthyroid subjects and in 55 healthy pregnant women: TT4, TT3, rT3, RT3-Uptake, TSH, FT4 and FT3. In addition, FT4-index, TT4/TBG, FT3-index, TT3/TBG and the balance of free hormone indices were calculated. The results of FT4 and FT3 measurement indicated an euthyroid status in late pregnancy. Though the FT4 and(More)
