We herein report a case of palmar fibromatosis, who was 78-year-old male and had had multiple variable-sized subcutaneous hard nodules on the left palm for 2 months. Histopathologic findings of the lesion revealed that the nodules were highly cellular, containing numerous spindle shaped cells. Ultrastructurally, intracytoplasmic micrcfilaments were present, and the nuclei were extremely indented by one or more transverse folds. These findings suggested the cells were myofibroblasts.

A 52-year-old man with multiple myeloma developed cutaneous nodules while being treated with melphalan and prednisolone. A biopsy specimen showed dermal infiltration by well differentiated plasma cells similar to those found on bone marrow biopsy. The use of peroxidase anti-peroxidase to demonstrate the monoclonality or polyclonality of the cytomplasmic immunoglohulins in the tumor cells revealed a positivity for IgG and 1 chain (ie, monotypic staining). Ultrastructurally, each plasmacytoma cell contained varyting amounts of rough endoplasmic reticulum and Golgi-apparatus. The cutnneous nodules completely disappeared after radiotherapy

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.

Treatment of the olecranon fractures by prolonged immobilization often results in limited elbow motion. With the use of tension band wiring, anatomical reduction was obtainable, and only a short period of immobilization was needed. We reviewed the cases of 17 patients who underwent surgical treatment of the olecranon fracture. All patients were treated by tension band wiring. In the overall series, we were able to obtain 53 percent excellent, 30 percent good, and 18 percent fair results.

Fractures of the tibial shaft are the most common among the long bone fractures, and have much difficulty in treatment due to their numerous complications. Thirty patients with fractures of the tibial shaft were treated with Ender nails under the image intensifier at the Department of Orthopedic Surgery, Yeungnam University Hospital from December 1986 to November 1991. The following results were observed. 1. The average age was 37.3 years and the number of male was three times of the female. The most common cause was traffic accident. 2. Twenty cases out of thirty one were closed fracture and the remaining 11 were open. The comminuted and segmental fractures were 18 (57.7%) in number and the most common fracture site was the middle one third (53%). 3. Average interval from injury to operation was 7.6 days and 19 cases showed associated injuries. 4. The mean duration of the bone union was 18.9 weeks and 2 cases showed the delayed union. 5. Twelve complications were noted such as shortening, varus deformity, delayed union, ankle motion limitation, nail irritation, and soft tissue infection.
