[Epiphyseal fractures and epiphysiolyses of the distal tibia].

In the years 1979, 1980 and 1981 a follow-up of 72 epiphyseal of the distal tibia was made. Half of the cases of epiphyseal fractures were treated conservatively, the other half operatively. Epiphysiolyses were treated conservatively without exception. In both groups disturbances of growth with partial closure of the growth plate and following malgrowth were found. The statistic evaluation of the case histories showed neither a sign of the cause nor a definite primary therapeutic influence on the disturbance of growth. On the basis of these results the classification effected to date of the epiphyseal traumas as well as their prognosis will be critically examined. From the clinicotherapeutic point of view epiphyseal fractures must be classified as joint lesions and epiphysiolyses as shaft fractures, even if the later are still lesions of the growth plate if considered from an anatomical point of view. On the basis of a clinically-orientated new classification of growth plate lesions, therapeutic principles are discussed.

Contextual modulation of memory consolidation.

We investigate olfactory memory consolidation in honeybees. Three experiments are reported that include 1024 animals in 28 experimental groups. After one pairing of odorant and sucrose reward, retention is typically nonmonotonic with a minimum 3 min after conditioning. This corresponds to the "Kamin effect" in vertebrates; the postminimum rise in retention is usually interpreted as reflecting memory consolidation. First, we test for the generality of this effect across four different odorants. The postminimum rise in retention was reproducibly observed for 1-hexanol but not for 1-octanol, limonene, or geraniol. Second, we investigate whether previous learning about the training context modulates subsequent memory consolidation. On the day before training, a reward was applied either upon placement into the future training context for 1 min, halfway during exposure or just before removal from the context. In the latter group, the 3-min minimum in retention was eliminated; thus, in that group, forward pairings of context and reward (i.e., context exposure begins before reward is applied) lead to an associative context memory that can modulate subsequent olfactory memory consolidation. Third, we found no evidence for a modulation of olfactory memory consolidation by pre-exposure to the odorant.

Determination of normal values using an automated coagulation timer for activated coagulation time and its application in dogs with hemophilia.

The present study was performed to determine normal values for the Medtronic HemoTec automated activated coagulation time (ACT) analyzer (Medtronic HemoTec Inc, Parker, CO, distributed in Switzerland by Convergenza AG, Vaduz, Liechtenstein), and to evaluate its ability to detect dogs with hemophilia. ACT was measured in 43 healthy dogs presented to the Companion Animal Hospital, University of Bern, Bern, Switzerland, with the Medtronic HemoTec ACT analyzer to determine normal values. The mean +/- 2 standard deviations (SDs) of the values obtained was defined as the normal range. ACT was measured 8-10 times on the same day in 6 dogs to determine repeatability. ACT also was measured in 11 dogs with hemophilia and compared with a conventional visual ACT measurement test and with the activated partial thromboplastin time (APTT). ACT values of the 43 dogs used to determine normal values ranged from 66.5 to 97.0 seconds (mean, 79.3 seconds; SD, 7.35 seconds; median, 78.5 seconds). A range of 64-95 seconds (mean +/- 2 SDs) was defined as the normal range for the tested device. Repeatability was poor (r = 0.256). ACT values measured with the automated device did not correlate with ACT values measured with a conventional visual test or with APTT Sensitivity of the test was 90.9%, specificity was 98.0%, and accuracy was 96.7%. Variability in the test results was large and may lead to incorrect results. The automated measurement device was not superior to the conventional visual method in evaluating dogs with hemophilia.

[Diabetic osteoarthropathy of the foot].

Neuropathic joint disease (described by J.M. Charcot in 1868) is now most commonly seen in patients with diabetic mellitus. We present a patient suffering from a characteristic diabetic neuro-arthropathy of the foot. We report the clinical features, roentgenographic signs, new diagnostic possibilities, and treatment.

Positive effect of balneotherapy on post-PID symptoms.

OBJECTIVE: The aim of this study was investigation of effect of balneotherapy after antibiotic treatment of PID. PATIENTS AND INTERVENTIONS: Fifty-seven patients with PID, diagnosed by laparoscopy, were treated by the same antibiotic scheme (oxytetracycline and metronidazole). After treatment of the acute phase, we studied the effect of balneotherapy (mud baths or mud packs, mineral baths, electrotherapies, and gynecological exercises) under sanatorium conditions in 30 patients. Twenty-seven patients without balneotherapy served as a control group. Second-look laparoscopy with dye insufflation was carried out about 12 weeks after the first operation. RESULTS: The rate of tubal occlusion after balneotherapy was 31% vs. 28% in patients without balneotherapy (P > .05). Moderate or severe adhesions seen at first look were similar in both groups (40.7% vs. 46.7%) and were nearly unchanged during second-look laparoscopy (44.4% vs. 46.6%). Twelve of 27 (44.4%) control patients had subjective or objective complaints compared to only 2 of 30 (6.7%, P < .05). CONCLUSION: Although balneotherapy after antibiotic therapy for acute PID does not improve fallopian tube patency, it is useful to reduce the frequency of lower abdominal pain.
