Two cases of unilateral calf enlargement following S1 radiculopathy are reported. "True" muscular hypertrophy could be confirmed by computerized tomography of the muscle. Muscle biopsy disclosed that fiber hypertrophy exceeded grouped fiber atrophy. In one case both fiber types were involved, and in the other mostly type 1 fibers were affected. Electromyography revealed dense pseudomyotonic activity and fasciculations. These findings are discussed in view of the current literature.

[Blood group antigens and ABH secretor status in dystrophia myotonica (Curschmann-Steinert)].

The linkage between the dominantly inherited Dystrophia myotonica and ABH-Secretor locus is well known. It has been used as a genetic marker for the early detection of heterozygous patients. Genetic counselling, however, requires exact knowledge of the gene combination. 25 persons from a special ambulance, patients and their advice seeking relatives, were examined for ABH, Lewis, Kidd, and Lutheran blood groups. Secretor test was performed from saliva. In 42% of the patients the combination of Dystrophia myotonica to the (Se) or (se) allele could not be exactly determined, nor in any of their relatives because the number of family members available for analysis was insufficient. Therefore this genetic marker is considered to be of limited practical importance for genetic counselling despite of its high theoretical value. The occurrence of lewis-b-antigen in the saliva of 3 nonsecretor patients cannot be explained yet.

[Proprioceptive deficit following cruciate lesions--afferent disorder or compensatory mechanism?].

It was suggested that the ACL has not only mechanical functions but also acts as proprioceptive organ. In cruciate deficient knees pathological patterns of muscle control were found. These findings could be caused by a disturbed afferent signal from the disrupted ACL or by secondary changes in muscle innervation, which shall protect the instable knee against subluxation. 33 patients with unilateral operative ACL repair (21 cases with primary suture, 12 cases with autogenous ligamentum-patellae-reconstruction; average post op 36.5 yr) were examined clinically and with the KT 1000 arthrometer (MEDMETRIC Inc.). Patients history was evaluated by using the LYSHOLM score. During a cycling task the electromyographic activity was monitored from the thigh muscles (M. vastus lat. and med., lat. and med. hamstrings). In comparison to the ACL deficient patients, we tested 25 healthy subjects of same age and activity level. In the ACL group the following differences to the normals were found: the M. vastus lat. showed a significantly delayed onset, earlier end and shorter duration. M. vastus med. had the same pattern; the delayed begin of activity and the shorter duration were statistically significant. M. biceps femoris showed a significant later onset and shorter duration. So did the medial hamstrings; the differences, however, were not statistically significant. There was no significant difference between operated and healthy leg in the ACL group. By comparing the primary sutures and the ligamentum-patellae-reconstructions no significant differences were found. The instable patients (KT 1000 > 3 mm) of the ACL group showed more distinct differences in the EMG pattern than the patients with stable knee joints.(ABSTRACT TRUNCATED AT 250 WORDS)
