Self-disclosure and loneliness]

This study examined the relationship between self-disclosure and loneliness. The self-disclosure questionnaire (ESDQ) and the loneliness scale (LSO, consists of two subscales, U-scale and E-scale) were administered to 114 female subjects (junior college students). Results show that self-disclosure scores were negatively related to the U-scale of loneliness (whether or not they believe in mutual sympathy among human beings), but not to the E-scale of loneliness (whether or not they are conscious of individuality of each individual). The results suggest that we have to specify the quality of loneliness in question, when we examine the relationship between self-disclosure and loneliness.     

Treatment of established osteoporosis with 1α (OH) vitamin D3 and low dose intermittent elcatonin (eel calcitonin derivative)

In addition to estrogen widely used all over the world for the prevention of postmenopausal osteoporosis, calcitonin and vitamin D derivatives are commonly employed to treat established osteoporosis at higher age in Japan. In order to critically assess the usefulness of vitamin D derivatives and calcitonin alone or in combination on the advancement of vertebral deformity at higher age, 32 osteoporotic patients with vertebral deformity with the mean age of 79 were randomly divided into 4 groups with indistinguishable age and severity of the vertebral deformity. Group 1 served as the control without specific medications for osteoporosis. Group 2 was treated with 10 units elcatonin (eel calcitonin derivative) injected intramuscularly twice a week. Group 3 was given 0.75 to 1.5μg/day 1α (OH) vitamin D₃ orally. Group 4 was given a combination of treatments used in Groups 2 and 3. In the lateral X-ray film of the spine taken prior to the test and every 6 months thereafter, the shape of the vertebral body T₈ through L₄ was monitored by measuring the anterior, central and posterior heights. Decrease of the vertebral height ratio; anterior or middle height/posterior or adjacent intact posterior height, by more than 20% of the original value or from above to below 0.80 both appeared to be inhibited during administration of 1α (OH) vitamin D₃. Such effect seems to be augmented by simultaneous administration of elcatonin. Actual decrease of vertebral height ratio values and the per cent fall from the original value significantly less in Groups 3 and 4 than in Group 1. Development of vertebral deformity assessed by the changes of the vertebral height thus appears to decrease during treatment with 1α (OH) vitamin D₃ especially together with calcitonin in established osteoporosis.     

Leiomyosarcoma originating in Meckel's diverticulum: Report of a case and a review of 59 cases in the English literature

A 49-year-old woman was referred to our hospital with complaints of epigastric colicky pain and high fever. Abdominal computed tomography and ultrasonography showed a solid tumor in the lower abdomen. Laparotomy revealed a neoplastic mass arising in Meckel's diverticulum; therefore, a segment of the ileum, including the tumor-possessing diverticulum, was resected with a lymph node dissection. A histologic examination confirmed the lesion to be leiomyosarcoma. In the English literature, 59 cases of leiomyosarcoma in Meckel's diverticulum were reported from 1941 to 1994. The majority of patients were in their 4th decade of life, with both sexes equally affected. The most frequent symptoms associated with this disease were abdominal pain with nausea, vomiting, and melena. The majority were larger than egg-size. Although Meckel's diverticulum is difficult to diagnose preoperatively, mesenteric arteriography may at times prove useful. The standard management of this particular tumor is wide segmental resection, including the tumor and diverticulum with lymph node dissection.     

Sex hormones and calcium regulating hormones in rheumatoid arthritis

Rheumatoid arthritis (RA) occurred frequently in women. Exogenous estrogen has been reported to alleviate the symptoms of patients with RA. But the implications of sex hormones and immunological abnormalities in RA remain to be elucidated. Therefore, we measured sex hormones (LH, FSH, estradiol, testosterone and prolactin), bone metabolic markers (midregion and carboxy terminal mainly recognized PTH1-84, intact PTH1-84, bone GLA protein and alkaline phosphatase), bone mineral, in lumbal bone with quantitative tomography (QCT) and with of cortex with microdensitometry in 52 females with RA and 46 females with osteoarthritis (OA) as a control group. Sex hormones and bone metabolic markers were analyzed as independent variables of serum LH, FSH and estradiol levels, using one way analysis, in patients with RA and OA. The more increased serum FSH and LH levels were, the more decreased serum estradiol levels were in both RA and OA groups, when they were considered as independent variables. These results indicate that the secretory function of pituitary and ovary axis hormones are normally enacted in RA. On the other hand, when the sex hormones of the patients under 53 years of age were studied in both groups, serum FSH adn LH showed significantly higher levels, while serum estradiol levels revealed decreased tendency in RA, compared with these in RA. Thus the pituitary ovary secretory function in patients with RA was suggested to be disturbed in early stage of age, indicating that the sex hormones would be partly implicated in calcium and bone metabolism in patients with RA.     

Comparison of p53 expression in proximal and distal gastric cancer: Histopathologic correlation and prognostic significance

Background: The overexpression of p53 has been found to be correlated with prognosis of some carcinomas, including gastric cancer, but no studies have reported on its relationship to the location of gastric cancer. In the present study, we compared the p53 expression of proximal and distal gastric cancer concerning histopathology and prognosis. Methods: A total of 170 tumors in the patients with proximal (80 cases) and distal (90 cases) gastric cancer were studied by immunohistochemical methods. Results: p53 immunopositivity was detected in 28.8% of all tumors. The p53-positive expression in proximal gastric cancer was higher than in distal gastric cancer (38.8% vs. 20.0%, p<0.05). A 5-year survival analysis showed that there is no significant difference between tumors that are p53 positive and p53 negative. No correlation was found between p53 expression and histopathology of gastric cancer. Conclusion: p53 nuclear staining is not useful as a prognostic indicator or as a parameter in gastric cancer.     

Effect of caffeine on expression of cardiac myosin heavy chain gene in adult hypothyroid and fetal rats.

Changes in cardiac myosin heavy chain (MHC) gene expression and isozyme transitions have been shown to be caused by developmental changes, hemodynamic overload, or the activity of various hormones. In this study, to examine whether caffeine, which has teratogenic effects on the fetal cardiovascular system, causes the distribution of cardiac MHC phenotype and, if so, to evaluate the mechanisms of the distribution of cardiac MHC phenotype by caffeine, we examined the effects of caffeine, theophylline, and cAMP on the cardiac MHC isoform transitions at the gene and protein levels using hypothyroid adult rats. Furthermore, we examined the expression of alpha- and beta-MHC gene in cardiac muscles of fetuses whose dams had received caffeine. The results showed that caffeine, theophylline, and cAMP caused accumulations of alpha-MHC mRNA and MHC isozyme V1. Furthermore, in the fetal hearts, it was recognized that caffeine induced an accumulation of alpha-MHC gene expression, as was also seen in the dams. However, this effect of caffeine on the heart was stronger in the fetus than in the dam. Intracellular cAMP concentration was increased by the administration of caffeine, theophylline, or cAMP, and the levels showed a positive correlation with those of alpha-MHC mRNA. These results suggest that the induction of alpha-MHC mRNA expression by the administration of caffeine may be induced by an increase in intracellular cAMP concentration.

Persistent left superior vena cava draining to left atrium with normal coronary sinus

In embryology, a persistent connection of the left superior vena cava to the left atrium rarely coexists with a coronary sinus. We herein report an unusual case of persistent left superior vena cava terminating in a left atrium with normal coronary sinus, which was revealed at the time of permanent pacemaker implantation after a second operation for recurrent left atrioventricular valve regurgitation. Because this anomaly had gone undiagnosed at the first operation, we were unable to diagnose it prior to the second operation, because the preoperative coronary angiogram clearly demonstrated a coronary sinus that was not dilated. We would have repaired the anomaly using a patch or other procedure had it been diagnosed before the second operation in order to prevent cyanosis or brain complications secondary to right-to-left shunting. One should always be on guard for this rare condition.
