The use of questionnaires in the evaluation of the functional capacity in rheumatoid arthritis.

The functional capacity of 46 patients with rheumatoid arthritis was assessed by means of two systems of investigation. Three different questionnaires were used. One set of each was filled out by the patient himself; the other with the help of the occupational therapist. The results obtained were tested for their reliability. In addition they were also compared to the Ritchie-Index (method of simple measurement of disease activity) of thirty patients. The disability of each patient could be assessed with sufficient precision. A correlation to the Ritchie-Index was also registered.

Serum ferritin and iron uptake by peripheral blood leucocytes in patients with active rheumatoid arthritis.

Rheumatoid arthritis is a systemic disease in which anaemia is common. The origin of the anaemia is usually multifactorial. Iron deficiency, a defect of release of iron from the reticulo-endothelial system is discussed. Ferritin content of monocytes, lymphocytes and polymorphs is found altered and mostly elevated in monocytes affected by serum iron deficiency. In all cell types iron uptake is related to transferrin saturation. Alterations against normal subjects in iron uptake, ferritin synthesis and iron incorporation into ferritin are mostly found in patients with serum iron deficiency.

[Analysis and evaluation of the rehabilitation measures in a 5-year prospective study of chronic polyarthritis in adults].

328 patients with a definite or classical adult rheumatoid arthritis were studied over a five-year treatment period. Two groups of patients were established from this total population. One group was treated primarily on an outpatient basis, with the treatment consisting always in medical care given by the general practitioner or a hospital outpatient department. The other group received inpatient treatment in a special rehabilitation centre once or twice a year, or according to necessity. During these measures the whole range of medical, vocational and social care was provided, as appropriate to the clients' needs. On evaluation of this five-year period, it is found that the patient group who had undergone periodical rehabilitative treatment every year demonstrated markedly better functional results than did the group which had almost exclusively received medication.

The use of thermography in the evaluation of the anti-inflammatory activity of feprazone on rheumatoid arthritis.

By means of the exploration of patients suffering from an active, unequivocal rheumatoid arthritis it was possible to show the unequivocal, and antiinflammatory effect of 4-phenyl-1,2-diphenyl-3,5-pyrazolidinedione (feprazone, Zepelin). Moreover, it was documented that thermography is a very suitable medium to furnish proof of this effect and can be used to the advantage of the patients in clinical routine. The physiological processes of the production and distribution of heat must be taken into account to avoid false interpretation of thermograms.

First 24 hours of acute pancreatitis. A biochemical and endocrine evaluation of initial versus repeated attacks.

Differences in metabolic homeostasis in 12 patients with initial vs. eight patients with repeated attacks of acute pancreatitis have been compared during the acute phase of the disease. As a group, subjects with a previous history of pancreatitis had significantly lower glucagon concentrations (P less than 0.002) for the over all 24-hour study period. Conversely, the serum concentrations of blood sugar, insulin, growth hormone, gastrin, cortisol, nonesterified fatty acids, triglycerides and cholesterol failed to distinguish between the two patient groups. Likewise, immunoreactive plasma parathyroid hormone and calcitonin levels were comparable in both patient populations. Of the measurements considered, it would appear therefore that plasma immunoreactive glucagon is the best indicator of previous pancreatic inflammation. Evaluation of parenchymal integrity during an episode of acute pancreatitis would be of prognostic and therapeutic value in this disease.

[Immunglobulin levels after kidney transplantation and during rejection crisis (author's transl)].

In the first three weeks after kidney transplantation the patients were examined for daily changes in immunoglobulin levels. Only very seldom was a decrease of IgM detected in our patients who had undergone splenectomy. During half of the rejection crisis there were indeed short periods of increase (spikes) in immunoglobulins. These were observed always before or concomitantly with the clinical diagnosis of a rejection reaction. In order to determine the connection between immunoglobulin-spikes and an approaching rejection episode the general one-sided binominal test was used. A significant relation was established between IgM peaks and an approaching rejection crisis. No such relation could be found for the IgA peaks observed. The IgG globulins showed no consistent pattern during a transplantation rejection. A persistent fall of the IgG globulins was noted in the first ten days after renal allograft with the immunosuppressive regimen of an initial gramme of methylprednisolon and high dosage of azothioprine. A good correlation was observed with the simultaneous depression of serum albumin concentrations. As losses of protein in urine are minimal (already confirmed by other authors), it must be assumed that in the first place a high rate of catabolism and a restriction in the protein synthesis is responsible for the decrease in the IgG globulins and the serum albumins.

[Cytological and biochemical studies in a case of "di Guglielmo's syndrome"].

Cytochemical, biochemical and disc-elektrophoretical studies are done on a patient with Di Guglielmo-syndrom. Cytochemical tests showed the wellknown results as: activity of acid phosphatase and alpha-naphthylacetatesterase at their typical sites, deposition of PAS- and Turnbull-positive material. Biochemical findings are done on LDH, cholinesterase, alkaline and acid phosphatase, G-6-PDH and pyruvatkinase. Abnormal high level of fetal hemoglobin was found only once during the whole observation. There was also an alteration in the isoenzym pattern of the acid phosphatase. The de- or increase at the biochemical examinations, the fact of fetal hemoglobin and the variation at the isoenzymes may be due to the changing in distribution of erythropoetic and granulopoetic cells.

[Cytochemical studies in megakaryocytes in hematologic diseases].

Bone marrow smears of 48 patients consisting of 12 normal cases, 36 patients with different haematological diseases-among them 9 cases of idiopathic thrombopenia, 4 cases of polycythaemia, and 9 cases of Hodgkin's disease - were examined cytochemically. Acid phosphatase, unspecific esterases, naphthol-AS-D-chloroacetate esterase, peroxydase, and leucin-aminopeptidase were represented; in addition the PAS reaction, fastgreen staining at pH 1.1, methyl-green pyronin staining and the lipid representation with Sudan black B were carried out. Besides those responses known from literature the different behaviour of acid megacaryocyte phosphatase in different haematological diseases must be particularly emphasized from all reactions.
