Post partum rubella vaccination and anti-D prevention]

The effectiveness of a routinely performed puerperal rubella vaccination was tested. Additional a possible adverse influence of simultaneously administered anti-D immunoglobulin on the effectiveness of the rubella vaccination was examined. Rubella antibody titers (HHT) in pregnant women were determined; after delivery puerperal women with titers of less or equal 1:16 were selected for rubella vaccination. 2 1/2 to 3 months later rubella antibody titers were done again. 15% of 130 vaccinated women did not show a conversion of the former negative titer or a low titer of 1:8 remained. Also reductions of the antibody titers were seen. When simultaneously rubella vaccination and anti-D immunoglobulin was administered only in 1 case out of 27 patients a negative titer remained after vaccination. The used anti-D immunoglobulin contained rubella antibodies of a titer 1:256 to 1:512; according to experimental studies, this concentration should not have any influence to the immunologic response of rubella vaccination. Our practic results could not confirm the reservations concerning simultaneous rubella vaccination and anti-D prophylaxis.     

Psychological aspects of diagnostic methods in pregnancy

Psychological effects and sequelae of prenatal diagnostics are presented using material of clinical trials and the results of client-centered counselling. All methods (ultrasound, alpha-fetoproteinscreening, amniocentesis and chorionic villous sampling) can only be understood with their effects upon mother - fetal bonding. A decision process, invasivity and discussion about a fetal malformation are the main characteristics of amniocentesis. High-risk populations like women with complicated pregnancies or advanced age profit most by prenatal diagnosis. The reactions and emotions of male partners are also discussed. The following guidelines for counselling are proposed: non-directive counselling dealing with facts and emotions, patient autonomy and preparation routines apt to reduce anxiety.     

C-erbB-2 oncogene amplification in breast cancer in correlation to steroid and epidermal growth factor receptor]

The amplification grade of oncogene c-erbB-2 was examined by the polymerase-chain-reaction-method in DNA's of 56 primary mammary carcinomas. 26 (46.4%) of these showed the amplified oncogene c-erbB-2. In the strongly amplified cases, the expression of the c-erbB-2 oncoprotein was verifiable immunohistochemically. Between the progesterone receptor status (PR) and the amplified c-erbB-2 oncogene there was a statistically proven dependency. No correlation was observed between the amplified c-erbB-2 oncogene and the epidermal growth-factor receptor (EGFR).     

Current concepts in the recognition and treatment of superior labral (SLAP) lesions

Pathology of the superior aspect of the glenoid labrum (SLAP lesion) poses a significant challenge to the rehabilitation specialist due to the complex nature and wide variety of etiological factors associated with these lesions. A thorough clinical evaluation and proper identification of the extent of labral injury is important to determine the most appropriate nonoperative and/or surgical management. Postoperative rehabilitation is based on the specific surgical procedure as well as the extent, location, and mechanism of labral pathology and associated lesions. Emphasis is placed on protecting the healing labrum, while gradually restoring range of motion, strength, and dynamic stability of the glenohumeral joint. The purpose of this paper is to provide an overview of the anatomy and pathomechanics of SLAP lesions and review specific clinical examination techniques used to identify these lesions, including 3 newly described tests. Furthermore, a review of the current surgical management and postoperative rehabilitation guidelines is provided.     

Variable sensitivity to noxious heat is mediated by differential expression of the CGRP gene

Heat sensitivity shows considerable functional variability in humans and laboratory animals, and is fundamental to inflammatory and possibly neuropathic pain. In the mouse, at least, much of this variability is genetic because inbred strains differ robustly in their behavioral sensitivity to noxious heat. These strain differences are shown here to reflect differential responsiveness of primary afferent thermal nociceptors to heat stimuli. We further present convergent behavioral and electrophysiological evidence that the variable responses to noxious heat are due to strain-dependence of CGRP expression and sensitivity. Strain differences in behavioral response to noxious heat could be abolished by peripheral injection of CGRP, blockade of cutaneous and spinal CGRP receptors, or long-term inactivation of CGRP with a CGRP-binding Spiegelmer. Linkage mapping supports the contention that the genetic variant determining variable heat pain sensitivity across mouse strains affects the expression of the Calca gene that codes for CGRPalpha.     

Electromyographic analysis of the rotator cuff and deltoid musculature during common shoulder external rotation exercises

STUDY DESIGN: Prospective single-group repeated-measures design. OBJECTIVES: To quantify electromyographic (EMG) muscle activity of the infraspinatus, teres minor, supraspinatus, posterior deltoid, and middle deltoid during exercises commonly used to strengthen the shoulder external rotators. BACKGROUND: Exercises to strengthen the external rotators are commonly prescribed in rehabilitation, but the amount of EMG activity of the infraspinatus, teres minor, supraspinatus, and deltoid during these exercises has not been thoroughly studied to determine which exercises would be most effective to achieve strength gains. METHODS AND MEASURES: EMG measured using intramuscular electrodes were analyzed in 10 healthy subjects during 7 shoulder exercises: prone horizontal abduction at 100 degrees of abduction and full external rotation (ER), prone ER at 90 degrees of abduction, standing ER at 90 degrees of abduction, standing ER in the scapular plane (45 degrees abduction, 30 degrees horizontal adduction), standing ER at 0 degrees of abduction, standing ER at 0 degrees of abduction with a towel roll, and sidelying ER at 0 degrees of abduction. The peak percentage of maximal voluntary isometric contraction (MVIC) for each muscle was compared among exercises using a 1-way repeated-measures analysis of variance (P<.05). RESULTS: EMG activity varied significantly among the 7 exercises. Sidelying ER produced the greatest amount of EMG activity for the infraspinatus (62% MVIC) and teres minor (67% MVIC). The greatest amount of activity of the supraspinatus (82% MVIC), middle deltoid (87% MVIC), and posterior deltoid (88% MVIC) was observed during prone horizontal abduction at 100 degrees with full ER. CONCLUSIONS: Results from this study provide initial information to develop rehabilitation programs. It also provides information helpful for the design and conduct of future studies.     

Recurrent and persistent nummuli after epidemic keratoconjunctivitis

Three observations of typical patients with persistent and recurrent nummuli after epidemic keratoconjunctivitis serve--pars pro toto--to demonstrate that longterm therapy with high-dosed topical steroid offers no therapeutic solution. This experience and other disadvantages of steroids in KCE (dry eyes) lead us to recommend not to apply topical steroids in KCE unless an adenovirus specific antiviral agent has become available for basic antiviral therapy.
