In vivo capillary microscopy findings and ophthalmoscopy findings in scleroderma.

We used in vivo capillary microscopy to examine the nailfold capillaries of 19 patients with scleroderma (18 women and 1 man; average age 56.6), and compared these findings with those obtained using an ophthalmoscope. The ophthalmoscope revealed hemorrhages in 68% of the patients, a reduction in the number of capillaries in 79%, avascular areas in 79%, and dilated capillaries in 84%. The findings from ophthalmoscopy showed a correlation of approximately 80% with those from capillary microscopy. Since the diagnosis of scleroderma can be confirmed with this instrument, we suggest that it be used when microscopy equipment is not available.

[Transcutaneous measures of oxygen partial pressure and capillaroscopic parameters as affected by naftidrofuryl in patients with obliterative arteriopathies, Fontaine stages II-IV].

Transcutaneous partial oxygen pressure on dorsum of foot was determined and capillaroscopy of big toes performed before and after infusions of naftidrofuryl (200 mg/l/h) and of 5% levulose to 30 patients with obliterative arterial disease of lower limbs, stages II to IV (10 patients in each stage). Naftidrofuryl provoked an increase in cutaneous partial oxygen pressure of 26.8 to 36.4 mm Hg (p less than 0.001) whereas no significant change was noted after 5% levulose. In addition, density of visible capillaries increased from 23.5 to 26.1/mm2 with naftidrofuryl. Severe stages of ischemia, evaluated as described by Fagrell, were improved by naftidrofuryl treatment. These findings suggest a favorable action of naftidrofuryl on cutaneous microcirculation distal to arterial obliteration at all Fontaine's stages.

[Vital capillary microscopy and with ophthalmoscope-detected findings in progressive systemic scleroderma].

Nineteen patients suffering from scleroderma (average age 56.6 years; 18 women, 1 man) were examined by in vivo capillary microscopy of the nail fold. The possibility of achieving results with the ophthalmoscope was examined. The correspondence between ophthalmoscopic and television microscopic results was evaluated. With the ophthalmoscope hemorrhages were found in 68% of the patients, reduction in the number of capillaries in 79%, avascular areas in 79%, and dilated capillaries in 84%. The correspondence between the findings of the two methods was 80% and more, so that examination of the nail fold capillaries with an ophthalmoscope can help to verify the diagnosis of scleroderma. This method should be employed whenever scleroderma is suspected and microscopical equipment is not available.

In-vivo capillary-microscopical findings in patients with thrombangiitis obliterans, progressive systemic scleroderma, and rheumatoid arthritis, respectively.

Fourty patients with thrombangiitis obliterans were examined to find out whether in-vivo capillary microscopy can contribute to the establishment of a diagnosis. No capillary-microscopical signs could be detected that are exclusive to thrombangiitis obliterans. Nevertheless typical signs as capillary lengthening, capillary branching (53%) and haemorrhagic margin (75%) are of considerable differential-diagnostic value when it comes to distinguishing a case of thrombangiitis obliterans from a case of degenerative arterial occlusive disease. In a further series of examinations, the nailfold area of patients with progressive systemic scleroderma was examined by in-vivo capillary microscopy and with an ophthalmoscope. The coincidence of the findings between the two methods was 80% and more, so that the examination of the nailfold capillaries with an ophthalmoscope can aid verify the diagnosis of scleroderma. In patients with rheumatoid arthritis capillary tortuosities (85%), capillary branching (53%) and increased venule visibility (55%) often occur. These are unspecific signs. Typically capillary-microscopical symptoms for the disease are not detectable.

Laser-Doppler examinations in persons with healthy vasculature and in patients with peripheral arterial occlusive disease.

Recently, a new procedure for noninvasive measurement of the microcirculation has been developed in the form of a helium-neon-laser Doppler apparatus with which the total erythrocyte flow through a cubic millimeter of skin is quantifiable. The authors used the procedure to examine 17 persons with healthy vessels, 36 patients with a degenerative occlusive disease of the peripheral arteries in Fontaine stages II-IV, and 5 patients with endangiitis obliterans. It is concluded that single measurements do not permit an assessment of microcirculatory conditions but that provocative tests (which are described), especially occlusion tests, make possible valid and reproducible statements and have a high selectivity with respect to the different stages of disease. By repeated measurements followed by calculation of mean values, a further reduction in intraindividual variability among the measurement results can be obtained. Laser-Doppler examinations of the skin constitute a new procedure with which quantitative statements on the blood flow through skin are feasible and from which interesting results can be expected, especially when used as an acute test.

[Vital capillary microscopic examination and transcutaneous pO2-measurements by intravenous prostaglandin E1 infusion].

The ability of a single i. v. application of 40 micrograms alprostadil (PGE1, mean therapeutic dose 0.62 microgram/kg body weight) to cause changes in capillary microscopy parameters and tcpO2 was investigated in an open study in 15 patients with peripheral arterial occlusive disease, Fontaine stage II-IV (8 women and 7 men, average age 70.1 and 70.0 years, respectively). Capillary microscopy investigations and oxygen tension measurements were carried out before and immediately after i. v. infusion of PGE1 or a 5% solution of laevulose using an intra-individual comparison. PGE1 led to an increase in the number of erythrocyte-filled capillaries per mm2, an improvement in the initial condition of the capillaries evaluated according to Fagrell and to a significant increase in the tcpO2, whereas no haemodynamic changes occurred at all after laevulose. These findings substantiate the view that PGE1 is also effective when applied intravenously distal from the arterial occlusion.

[Nicergoline and cerebral performance insufficiency. Observations in 1 year treatment controls].

In 1,366 patients the effect of Nicergoline (Sermion) on symptoms was recorded for one year. Individual symptoms improved to varying degrees in the patients observed. Many influences were responsible for the recorded improvement in the condition of the patients. These included, apart from the selection, placebo effects, the effect of suggestion, increased personal attention due to the need for monitoring examinations, and the pharmacodynamic effects of the active substance. The fact that the improvement rate of several symptoms such as lack of concentration, impairment of memory, decrease in alertness, dizziness and noises in the ear was analogous to that found in placebo-controlled doubleblind studies of other workers permits the assumption, that not so much the effects of placebo and suggestion but above all the pharmacodynamics of the active substance was the important factor. Treatment, which lasted for a year resulted in an improvement in some symptoms even during the second half of the year but not in others. This provides information on the indication for long-term treatment. Analysis of the individual parameters throws light on the reliability of the information provided by the examining physician, the patient compliance and the psychological effects of the physician's activities. Parameterized values are sometimes recorded more reliably by interested auxiliary medical staff than by physicians who feel alienated from their proper duty by such technical tasks.

[Naftidrofuryl in arterial occlusive disease. Controlled multicenter double-blind study with oral administration].

The efficacy of naftidrofuryl ( Dusodril ) for treatment of stage II arterial occlusive disease was evaluated in a controlled multi-centre study in a total of 104 out-patients with angiographically documented localization of occlusion. The therapeutic effect was assessed over three months by measurements of walking distance using standardized treadmill conditions. Further parameters were venoocclusive plethysmography and Doppler ultrasonography measurement of pressures. The complaint-free walking distance increased significantly during daily application of 600 mg naftidrofuryl orally (n = 54) during the 12-week assessment period when compared to the placebo group (n = 50). Taking the intraindividual variability of 17.2 m in assessment of walking distance into account, the increase of painless walking of 93 m after treatment for 12 weeks in the active-drug group is considered the result of treatment-induced increased performance.

Naftidrofuryl in chronic arterial disease. Results of a controlled multicenter study.

In a double blind, randomized multicenter study naftidrofuryl, a vasoactive substance, was compared with placebo in the treatment of 104 patients with chronic arterial occlusive disease. After a run-in period of four weeks the patients received either naftidrofuryl (600 mg daily) or placebo over 12 weeks. The pain-free and the total walking distances improved significantly in both groups. However, the difference in the improvement of the pain-free walking distance was significant (p less than 0.02) in favour of naftidrofuryl. There also was a difference in the improvement of the total walking distance in favour of naftidrofuryl which was not significant. The results indicate that naftidrofuryl has a beneficial effect on the symptoms and lengthens the painfree walking distance in patients with arterial occlusive disease.

[Doppler ultrasound studies of the extracranial cerebral vessels in migraine patients after ergotamine tartrate administration].

Doppler ultrasound investigations were done in 20 patients with migraine during the symptom-free interval after oral administration of 2 mg and 6 mg ergotamine tartrate. The observed changes of end-diastolic flow velocity as a measure of peripheral total resistance permit simultaneous assessment of the vasoconstrictor effect of ergotamine in the perfusion area of the internal and external carotid arteries. A dosage of 2 mg led to an exclusive increase of resistance in the external carotid artery area without significant changes in the internal carotid area. A maximal therapeutic dosage of 6 mg ergotamine tartrate did not lead to a significant increase of the vasoconstrictor effect in the external carotid circulation. In addition, a barely registrable increase of resistance in the internal carotid area could now be observed.

[Platelet aggregation inhibition with calcium dobesilate].

In 52 patients with pathologically increased platelet aggregation the effect of a 4-day oral treatment of 500 mg, 1000 mg and 1500 mg calcium dobesilate (Dexium 500) on spontaneous platelet aggregation was assessed using PAT III of Breddin. In comparison to placebo 1500 mg calcium dobesilate reduced platelet aggregation significantly, 1000 mg and 500 mg calcium dobesilate, however, didn't influence platelet aggregation.
