Microtubular inclusions in normal skin of systemic lupus erythematosus patients

Biopsy specimens of clinically normal skin of 9 consecutive patients with SLE were examined ultrastructurally to determine the presence and frequency of microtubular inclusions. Ten blood vessels were examined in each specimen; every specimen contained at least two positive blood vessels, and some contained 80 to 100% positive vessels. No correlation was found between the frequency of the inclusions and either the disease duration or antinuclear factor titer. The inclusions tended to be more frequent in patients with more acute disease. The absence of inclusions in normal skin may mitigate a diagnosis of SLE.     

End-stage periventricular leukomalacia: MR evaluation

A prospective study was performed to assess the capabilities of magnetic resonance (MR) imaging in evaluation of end-stage periventricular leukomalacia (PVL) in six children, aged 31-54 months, in whom PVL had been documented by neurologic ultrasonography during the neonatal period. Eight children of similar age (four premature infants and four full-term infants) with normal neurologic development served as controls. A characteristic triad of PVL abnormalities was seen on MR images: (a) abnormally increased periventricular white-matter signal intensity on the first and second echo images of a T2-weighted sequence (repetition time = 2,000-2,400 msec, echo times = 20 or 30 and 80 msec), most commonly observed in the trigone regions of the lateral ventricles bilaterally; (b) marked loss of periventricular white matter in these regions of abnormal signal intensity, predominantly in the periatrial regions; and (c) compensatory focal ventricular enlargement adjacent to regions of abnormal signal intensity. In patients with the classic periatrial distribution of PVL lesions, general correlation between the degree of neurologic impairment and the severity of MR abnormalities was demonstrated. MR imaging was useful in detecting subtle forms of PVL in cases in which neurologic damage was subclinical.     

Procoagulant activity of reversibly acylated human factor Xa

The plasma clotting factors used to treat hemophiliacs who have developed inhibitory antibodies have a shared history of limited clinical safety and utility. To improve on existing bypass factors, we have developed a reversibly acylated form of human plasma factor Xa capable of providing a time-dependent release of procoagulant activity. Factor Xa was treated with p-amidinophenyl p'-anisate to generate anisoyl Xa. The chemical modification of the protein involves acylation of the active site serine residue of factor Xa. Anisoyl Xa deacylated in a time, pH, and temperature-dependent manner. Active factor Xa generated on deacylation of anisoyl Xa exhibited amidolytic and prothrombinase complex activities in in vitro assays, the level being comparable to those of untreated factor Xa. When Anisoyl Xa was infused into rabbits, active factor Xa was generated on deacylation of the acylated enzyme, which shortened the activated partial thromboplastin time (APTT) in a dose-dependent manner. The duration of effect on rabbit APTT could be directly correlated to the level of human plasma factor Xa. Because anisoyl Xa bypasses the "tenase" complex that is compromised in hemophilia A and B and is unaffected by inhibitory antibodies, it has the potential to be used as an effective bypass therapy.     

Konsensuspapier der Deutschen Gesellschaft für Pneumologie und Beatmungsmedizin (DGP) und der Deutschen Gesellschaft für Kardiologie – Herz und Kreislaufforschung (DGK) zur Diagnostik und Therapie der kardialen Sarkoidose

Sarcoidosis is a multisystemic granulomatous disorder which affects the respiratory system in the majority of the cases. Cardiac manifestations are found in less than 10?% of the affected cohorts and show a large heterogeneity based on the ethnic background. Cardiac sarcoidosis is not only found in patients with rhythmogenic heart disease, such as atrial and ventricular fibrillation but also in all phenotypes of cardiomyopathy. The overall morbidity and mortality caused by cardiac sarcoidosis in Germany is unclear and no large prospective international studies have been published on this topic. This consensus paper on diagnostic and therapeutic algorithms for cardiac sarcoidosis is based on a current literature search and forms an expert opinion statement under the auspices of the German Respiratory Society and the German Cardiac Society. The rationale of this statement is to provide algorithms to facilitate clinical decision-making based on the individual case situation.     

The effects of comprehensive home physiotherapy and supervision on patients with ankylosing spondylitis--a randomized controlled trial

Fifty-three patients with ankylosing spondylitis (AS) were randomly allocated; 26 experimental patients received physiotherapy and disease education, 27 control patients received neither. The primary treatment outcome was change in spinal mobility measured at 4 months by fingertip-to-floor distance. Experimental patients had more improvement in fingertip-to-floor distance (p2 less than 0.004) and in function (p2 less than 0.001) than control patients. Physiotherapy with disease education is effective in the treatment of patients with AS.
