Out of 24 patients with laryngeal papillomatosis 6 (5 female, 1 male) suffered from repeated relapses and underwent long-term treatment with alpha-IFN-therapy. Age at onset of the disease: 1 5/12-16 2/12 years. Duration of illness: 1-7 years, with several relapses were treated surgically and with laser-coagulation. Three out of 6 patients had a tracheal cannula and were cauterized by podophylline at 2-4 week intervals. IFN was given in dosages of 5-20 X 10(4) U/kg 2 or 3 times a week. IFN-dosage for each patient was determined using the induction kinetics of (2'-5')-oligo(A)synthetase (OAS) in the mononuclear cells of the circulating blood of patients with laryngeal papillomatosis. A continuous effect could be achieved by the dose of IFN determined in the described way always before OAS activity decreased to its initial level. All 6 patients responded favorably to the alpha-IFN-therapy. Two patients treated only with IFN showed remission without relapses. In 2 cases IFN was successfully used to prevent relapses after surgical treatment and laser-coagulation. In 2 patients with papillomatosis extending into the main bronchi the disease could only be brought to a standstill, i.e. it was not necessary to remove the papillomas. Two out of 3 patients with laryngeal papillomatosis could be decannulated. Long-term therapy following the above described principles is efficient and without significant side-effects. Three patients are in treatment for more than 3 10/12 years. 相似文献

Objective. To determine the dosage of gadobenate dimeglumine (Gd-BOPTA) necessary for MRI of rheumatoid arthritis of the wrist.
Design and patients. Seven wrists inflamed with rheumatoid arthritis were imaged using a dedicated 0.2-T MR unit. Four cumulative dosages of 0.0125,
0.025, 0.05 and 0.1 mmol/kg body weight (BW) Gd-BOPTA were tested. Three-dimensional T1-weighted gradient-recalled echo sequences
(GRE; TR: 100 ms, TE: 18 ms, flip angle 90°, 4:55 min) were acquired prior to an intravenous injection and after each additional
dosage of Gd-BOPTA. Relative enhancement, signal-difference-to-noise ratios (SDNRs) and the size of the inflamed tissue were
quantified. Three radiologists independently evaluated the image quality, the size and the contrast of the enhancing tissue.
Results. The readers agreed on a dose of 0.05 mmol/kg BW as satisfactory for the evaluation of the size of the inflammatory tissue
and for determination of bone involvement (κ=0.9, P<0.001). Highly inflammatory pannus was depicted with adequate image contrast using 0.025 mmol/kg BW Gd-BOPTA. According to
the SDNR and relative enhancement findings, a dose of 0.05 mmol/kg BW suffices for both off-center and centered regions of
tissue inflammation (t-test, P<0.05).
Conclusion. Gadolinium-BOPTA is an alternative contrast agent for MRI of rheumatoid disease. This study shows that a dose of 0.05 mmol/kg
BW suffices at low field strength.

Summary Four basic dyes, two thiazine dyes (toluidine blue, methylene blue) and two acridine dyes (trypaflavine, acridine orange), enhance the induction of interferon by polyIC in L cells. This effect is more likely the result of charge neutralization than protection of the polynucleotide against degradation by RNase.Abbreviations poly(I) · poly(C)

OBJECTIVE: Determination of early prognostic factors in patients with recurrent respiratory papillomatosis is extremely important, so the major goal of our prospective, multicentre study was to evaluate (1) the feasibility of various factors to determine prognosis of the clinical course, as well as (2) the response to interferon-alpha therapy in recurrent respiratory papillomatosis. METHODS: Forty-two patients with recurrent respiratory papillomatosis were treated with interferon-alpha (3 MU/m(2) three times per week; mean therapy duration was 2.7 +/- 1.8 years) in 1983-1994 and followed-up until 2003. Human papilloma virus (HPV) type, recurrent respiratory papillomatosis severity and 2',5'-oligoadenylate synthetase activity were determined by standard methods and analysed for correlation with the results of long-term clinical outcome. RESULTS AND CONCLUSION: Patients with HPV type 11, a severity score >4, a high number of surgical procedures prior to interferon-alpha therapy and a high basal 2',5'-oligoadenylate synthetase activity should be considered at high risk of an aggressive clinical course, often with spread to lower airway passages, malignant transformation and death. Human papilloma virus type, score for recurrent respiratory papillomatosis severity, number of surgical procedures and 2',5'-oligoadenylate synthetase activity showed significant association with response to interferon-alpha therapy and the long-term clinical course, so these factors have value in predicting prognosis in recurrent respiratory papillomatosis. 相似文献

In a period of ten years 159 residents were admitted to a transitional home. 90% of them were diagnosed as chronic schizophrenics with a marked psychic and social handicap. With an average age of 28.7 years and a mean duration of illness of 6.8 years most of the patients had been hospitalized several times; 95% had no job, lived on social assistance or were invalidity pensioners. There was poor success in vocational rehabilitation (22%). Better results were seen in solving the housing problems, showing a clear-cut tendency to move from the family of origin into protected group homes or independent living. Positive effects of social training with gains in life-coping abilities and social competence, i.e., in autonomy in everyday life could be observed as well. 相似文献

Two cases of Charles Bonnet Syndrome (CBS) showing an unusual history are reported. In a 67-year-old man visual hallucinations developed 38 years after bilateral optic nerve damage due to methyl alcohol poisoning. A 78-year-old woman suffering from bilateral advanced cataract experienced visual hallucinations which ceased after improvement of vision resulting from cataract extraction. Sensory deprivation and--possibly--central neurophysiological disturbance are to be regarded as important pathogenetic factors. Signs of cerebral dysfunction which could be relevant to the pathogenesis of CBS were revealed by the EEG. 相似文献
