Membranous glomerulonephropathy is the most common cause of nephrotic syndrome in adults and idiopathic autoimmune thrombocytopenic purpura is autoimmune disease caused by autoantibody to platelet membrane glycoprotein. Although there are some pathologic similarity between two diseases that 'membrane attack complex' play a role in pathologic process, but only 3 cases worldwide are reported about membranous glomerulonephropathy associated with idiopathic autoimmune thrombocytopenic purpura. So we report a case of sixty eight years of woman who had symptoms of generalized edema, foamy urine, anorexia and thrombocytopenia on admission and developed more severe symptomatic thrombocytopenia there after. She was diagnosed membranous glomeulonephropathy on renal biopsy and also diagnosed idiopathic autoimmune thrombocytopenic purpra on bone marrow biopsy and on the basis of exclusion.

The damage which radiation produces in tissues such as the lungs can be discussed at the molecular, biophysical, cellular, and organ levels. The cellular effects of irradiating the lungs are related to the histologic and clinical sequelae. In the present study the right lung of rabbits were exposed to single dose of 20 Gy of X-irradiation. Animals from each group were sacrificed monthly for 6 months postexposure. Sections of lung were examined by light microscopy(LM) and by transmission electron microscopy(TEM). Multiple exudative lesions were seen at 2 months after the 20Gy irradiation, and they progressed to a proliferative and then reparative fibrotic lesion by 6 months. Changes in epithelial lining of lung components, particulary the presence of type II pneumocytes were found by both LM and TEM. Capillary endothelial damages were less pronounced. The possible implication of cellular components in radiation pneumonitis and fibrosis is discussed.

BACKGROUND: Most patients with gastric cancer have metastatic disease at first diagnosis and need palliative chemotherapy. Unfortunately, the response duration of the first line chemotherapy is usually short and most patients need the second line therapy during their disease process. The action mechanism of continuous infusion of 5-FU is different from bolus 5-FU and we can expect that among patients who failed on bolus 5-FU, some patients will achieve response to infusional 5-FU. So, we planned to evaluate the efficacy and safety of leucovorin and infusional 5-FU as a second line regimen for the metastatic gastric cancer refractory to regimen containing bolus 5-FU. METHODS: Patients with recurred or metastatic gastric cancer unresponsive to regimen containing bolus 5-FU were entered into this study. The mixture of 5-FU 1,000 mg/m2/day and leucovorin 50 mg/m2/day was infused continuously for four days and this treatment was repeated by every three weeks. RESULTS: From March, 1996 to July 2001, 25 patients were enrolled in this study. One patient showed a partial remission, 9 stable disease and 15 progressive disease. The overall response rate was 4%. The median time to progression was 73 days and the median duration of overall survival was 140 days. Among total of 92 cycle chemotherapy, leukopenia, granulocytopenia and thrombocytopena of WHO grade 3 or 4 were observed in 7.6%, 12.0% and 14.1%, respectively. Stomatitis, nausea or vomiting of WHO grade 3 or 4 were 13.1%, 5.4%, respectively. Neutropenic infection occurred in two patients. CONCLUSION: The LF regimen was well tolerated with minimal toxicities and showed low effect as the second line chemotherapy for the patients with gastric cancer.

BACKGROUND: As a tumor marker, lactate dehydrogenase is widely used as a prognostic factor in malignant lymphomas and a therapeutic monitor in ovarian dysgerminoma. But in other tumors, the clinical role of lactate dehydrogenase is not clear yet. To investigate the role of LD as a tumor marker, we analyzed patients with various cancers and high LD level. METHODS: The serum LD level was assayed in the cancer patients who visited our hospital. For the patients with high LD level, isoenzyme was also assayed. The response of chemotherapy was classified according to the WHO criteria into remission, which covers complete and partial remission, stable disease and progressive disease. The relationship between the tumor response and the LD response was examined in terms of sensitivity, specificity and positive predictive value. RESULTS: A total of 100 cancer patients were found to have high LD level; among them, 76 patients underwent chemotherapy. There were 38 patients with LD increased and 38 patients with LD decreased after chemotherapy. No patient was in remission, 6 patients in stable disease, and 32 patients in progressive disease among 38 patients with increased LD level; 18 patients in remission, 10 patients in stable disease, and 10 patients in progressive disease among 38 patients with decreased LD level. The sensitivity of LD increase in the patients with tumor progression is 76.2%, the specificity 73.7%, and the positive predictive value 84.2%(71.4%, 25.0% and 76.9% respectively in stomach cancer patients). The sensitivity of LD decrease in the responsive patients is 100%, the specificity 65.5% and the positive predictive value 47.4%.(100%, 64.7% and 14.3% in stomach cancer patients respectively). The LD isoenzyme pattern was not specific in this study. CONCLUSION: Serum LD measurement may be helpful in monitoring tumor response, especially for stomach cancer, after chemotherapy.

Psychiatry Investigation 2024;21(11):1193-1202
Objective:
Dentists encounter unique occupational challenges, including stress, depression, and anxiety, that can impact their mental well-being. Therefore, it is essential to identify dentists’ mental health statuses and the factors influencing them. Understanding the heterogeneity in dentists’ mental health is crucial for tailored interventions. To investigate different mental health profiles within the dentist population and understand the characteristics of each type.
Methods:
In this cross-sectional study, we surveyed 261 Korean dentists from a sample of 1,520. Using latent profile analysis, participants were classified into distinct mental health profiles based on self-reported stress, depressive symptoms, anxiety, and sleep quality. Demographic and occupational variables were analyzed to explore their association with mental health profiles.
Results:
Three distinct mental health profiles were identified: high, moderate, and low. Factors such as drinking frequency, socioeconomic status, income, and work hours significantly influenced profile classification. Significant differences in job satisfaction were observed among the profiles.
Conclusion
This study underscores the importance of personalized interventions to address the specific needs of each mental health profile, aiming to improve job satisfaction and overall mental health in the dental profession.

A 76 year-old female who was diagnosed with multiple myeloma (IgG, lambda) had received bortezomib, melphalan and prednisolone as first-line treatment. After completing six cycles of chemotherapy, her serum monoclonal protein level decreased from 7.28 g/dL to 0.65 g/dL, indicating a partial response. However, at the next scheduled visit she complained of slowly progressing dyspnea. On chest X-ray, newly developed pleural effusion was found, and rapidly progressing extramedullary plasmacytoma was detected in the anterior mediastinum on chest computerized tomography. However, there was no change in her serum monoclonal protein level. In Korea, extramedullary involvement is encountered in 5% of patients with multiple myeloma. However, evaluation of treatment response using solely the serum monoclonal protein level may not accurately reflect disease status in these patients.
