The purposes of this study were to test the negative association between schizophrenia and rheumatoid arthritis(RA) and to clarify the role of prolactin and estrogen as protective factors in this association. The author compared the prevalence rate of RA between 561 patients with schizophrenia and 222 patients with mood disorder. For investigating the role of estrogen and prolactin, the author checked the plasma prolactin and estradiol level in 80 patients with paranoid schizophrenia and 77 patients with RA. The results were as follows. 1) Epidemiological data The prevalence rate of RA in the schizophrenic group was 0/561 and that of RA in the mood disorder group was 2/222. To compare these results between two groups, the author applied the Binomial test using the average prevalence rate of RA(0.8%) in the general population as a reference rate. The prevalence rate of RA in the schizophrenic group was significantly lower than that of RA in the general population. However, the prevalence rate of RA in the mood disorder group was not significantly different to that of RA in the general population. 2) Comparison of plasma prolactin and estradiol level between two groups. The plasma level of prolactin in the schizophrenic group was significantly higher than that of prolactin in th RA group(p=0.000). However, the plasma level of estradiol in the schizophrenic group was significantly lower than that of estradiol in the RA group(p=0.017). These results were not consistent across gender. To contrast with the results in the female group, which were consistent with the results in the total subjects, for the male group, the plasma levels of prolactin and estradiol in the schizophrenic group were significantly higher than those of prolactin and estradiol in th RA group. These results support the results of previous studies which confirm the negative association between schizophrenia and RA. These results also suggest that the elevation of plasma prolactin level in the patient with schizophrenia has a antirheumatic effect while the elevation of plasma estradiol level in the patients with RA has a anti-schizophrenic effect, and that these effects act as a possible mechanism in the negative association between two disorders. However, these results suggest that this association is specific to female patients.

Owing to the advancement of imaging techniques which include the CT scan, it became easier to evaluate fracture patterns of calcaneal fractures accurately. Moreover, it is possible to obtain good results with operative treatment as a consequence of the development of good operative equipment and new operative technique. In 1988, Regazzoni and Benirschke in 1990, recommended L-shaped extensive lateral approach for calcaneus which provide extensive exposure of calcaneus and so allow easier reduction and fixation. We carried out L-shaped extensive lateral approach in 11 cases from June, 1993 to April, 1994. This approach did not produce any skin problems and allowed excellent anatomical reduction and fixation. But we experienced some severe causalgia on the heel region in several cases. We tried to analyse the cause of pain and concluded that it was the damage to the lateral calcaneal branch of the sural nerve. We are reporting the problems of tbis approach.

The posterior cruciate ligament is the primary static restraint to posterior translation of the tibia and provides proprioception within the knee. The goals of treatment in the injuries of PCL are restoration of normal tibiofemoral stability and reduction of long term osteoarthrosis of the knee. The purpose of this study is to cornpare functional outcome, muscle power, and posterior stability between conservative treatment and reconstruction with autogenous RPTB augmented with Kennedy LAD in PCL injuries. Twenty-seven patients with PCL rupture who have been treated from November 1990 to May 1996 were reviewed. The patiens were divided into conservative group and reconstruction group. Conservative treatment was done in 15 patients and reconstruction by autogenous bone patellar tendon bone with Kennedy LAD was performed in 12 patients. All patients were evaluated with posterior stress x-ray films, KT-2000 knee ligament arthrometer, Cybex 340 isokinetic dynamometer, subjective Cincinnati symptom rating scale and Lysholm knee score, complication. The results were as follows; 1. Mild and moderate posterior instability was remained in spite of BPTB graft and need more stable fixation technique and vigorous rehabilitation program. 2. At the angular velocity of 90 degree/sec and 180 degree/sec, the muscle strenth of quadriceps was decreased after PCL injury in both group in the test of Cybex 340 isokinetic exercises. The power of hamstrings were not changed after PCL injuries. 3. Average Lysholm knee score was 89 points in reconstruction group and 78 points in conservative group and average Cincinnati symptom-rating scale was 8.4 points in reconstruction group and 7.1 points in conservative group. More satisfied functional results and subjective symptoms were revealed in the reconstruction group and statiscal significancy (p<0.05) was showed when comparing conservative group with reconstruction poup. 4. Good clinical results did not always coincidence with lesser posterior instability and clinical results were influenced by associated injury of the knee. The more combined ligament injury of the knee, the worse clinical results.

Background and OBJECTIVE: There has been a few case reports of anaphylaxis due to honeybee in Korea. In order to observe the clinical feature of bee sting anaphylaxis. Moderials and methods: Six patients living in Kyunggi province area were referred under history of anaphylaxis after the bee sting. Atopy was defined by skin prick test result to common inhalant allergen. Serum specific IgE antibody to each bee antigen was detected by radioimmunoassay to identify the causative bee. RESULTS: All six cases were female. Three had atopy and four had combined allergic diseases such as allergic rhinitis, asthma, and urticaria. The etiologic bees consisted of yellow jacket (6 cases), paper wasp (4 cases), yellow hornet (3 cases), white faced hornet (1 case) and honey bee (1 case). Four cases had experienced anaphylaxis after ant bite and they showed positive result on specific IgE to imported fire ant. Specific immunotherapy against causative bee venom was begun using bee venom extracts from Bayer (USA) based upon results of specific IgE anti-body to bee venom. CONCLUSION: The yellow jacket is the most common cause of bee venom anaphylaxis in this area. Further studies will be needed to evaluate possible cross-reactivity between bee and ant venom.
