Proliferative activity of a malignant tumor is known to reflect its biological aggressiveness. Proliferating cell nuclear antigen (PCNA) is a marker of cellular proliferation, and silver-stained nucleolar organizer regions (AgNORs) have been shown to correlate with ploidy and proliferative activity of cells. In transitional cell carcinoma of the renal pelvis, the prognostic value of these markers has not been well defined. We studied PCNA expression and the AgNORs count in 22 transitional cell carcinoma of the renal pelvis to assess their prognostic significance compared with their cumulative survival rate, the stage of disease and histopathologic features of the tumors. An immunohistochemical method and a standard colloidal silver staining were used. The mean percentage of PCNA positivity (PCNA index) and the mean number of AgNORs per nucleus (AgNORs score) were determined. In a multivariable analysis, PCNA indexes were significantly associated with tumor stage (p=0.024), whereas AgNORs scores were not significantly associated with the stage or histopatholgic features of the tumors. Histologic grade was correlated to disease stage at a significant level (p=0.000). But there was a trend of low tumor PCNA-indices or AgNORs counts with survival advantage for patients, but this did not reach statistical significance. The results suggest that the fraction of PCNA positive nuclei would be useful for investigating the malignant potential of renal pelvic cancers, although their clinical use as markers of biologic behavior may be limited.

The prognostic significance of the squamous cell carcinomas of the oral and oropharynx have been evaluated to identify those features associated with aggressive biologic behavior according to the immunologic and histologic characteristics. For determining prognostic indicators, the authors performed immunohistochemical staining of p53 and epidermal growth factor receptor(EGFR) in 29 cases of squamous cell carcinomas of the oral and oropharynx. The expression rate of p53 was 51.7%, that of EGFR was 96.6%, and overexpression rate of EGFR was 41.4%, however there were no statistical significance between the reactivity of EGFR, p53 and clinicopathological features such as primary stage, nodal stage, clinical stage, death and histologic grade.

OBJECTIVE: We investigated the efficacy and tolerability of paliperidone extended-release (ER) tablets in patients with first-episode psychosis (n=75). METHODS: This was an 8-week, open-label, multicenter trial. The primary outcome variable was scores on the Positive and Negative Syndrome Scale (PANSS); secondary measures included the Scale for the Assessment of Negative Symptoms (SANS), the Cognitive Assessment Interview (CAI), and the Global Assessment of Functioning (GAF). To assess safety, we measured drug-related adverse events, weight, lipid-related variables, and prolactin and administered the Simpson–Angus Rating Scale (SARS), the Abnormal Involuntary Movement Scale (AIMS), the Barnes Akathisia Scale (BAS), the Arizona Sexual Experiences Scale (ASEX), and the Udvalg for Kliniske Undersogelser side effect rating scale (UKU). RESULTS: The administration of paliperidone ER resulted in significant improvement in the PANSS, SANS, CAI, and GAF scores (p<0.001) over time. This improvement was evident as early as 1 week. The most frequent adverse events were akathisia, somnolence, anxiety, and sedation, which were well tolerated. Modest increases in weight and lipid profiles were also noted. Prolactin levels were substantially increased at the endpoint in both male and female patients. CONCLUSION: These results indicate that paliperidone ER is effective and is characterized by good tolerability in the treatment of positive and negative symptoms and cognitive functioning in first-episode psychosis.

BACKGROUND: C-arm fluoroscopy equipment is important for interventional pain management and can cause radiation injury to physicians and patients. We compared radiation safety education and efforts to reduce the radiation exposure of pain specialists. METHODS: A survey of 49 pain specialists was conducted anonymously in 2016. The questionnaire had 16 questions. That questionnaire was about radiation safety knowledge and efforts to reduce exposure. We investigated the correlation between radiation safety education and efforts of radiation protection. We compared the results from 2016 and a published survey from 2011. RESULTS: According to the 2016 survey, all respondents used C-arm fluoroscopy in pain interventions. Nineteen respondents (39%) had received radiation safety education. Physicians had insufficient knowledge about radiation safety. When the radiation safety education group and the non-education group are compared, there was no significant difference in efforts to reduce radiation exposure and radiation safety knowledge. When the 2011 and 2016 surveys were compared, the use of low dose mode (P = 0.000) and pulsed mode had increased significantly (P = 0.001). The number checking for damage to radiation protective garments (P = 0.000) and use of the dosimeter had also increased significantly (P = 0.009). But there was no significant difference in other efforts to reduce radiation exposure. CONCLUSIONS: Pain physicians seem to lack knowledge of radiation safety and the number of physicians receiving radiation safety education is low. According to this study, education does not lead to practice. Therefore, pain physicians should receive regular radiation safety education and the education should be mandatory.

PURPOSE: To evaluate the effect and prognostic factors of automated thermodynamic treatment (thermal compression therapy device [KCL 1100®]) for Meibomian gland dysfunction (MGD). METHODS: Patients (48 eyes of 24 subjects) with MGD were recruited for a prospective clinical trial. Patients received 15-minute treatments twice a day using the KCL 1100®. Severity of dry eye symptoms were evaluated using the Standard Patient Evaluation for Eye Dryness (SPEED) and Ocular Surface Disease Index (OSDI), and severity of Meibomian gland function was evaluated using the Meibomian gland expressibility (MGE), Meibomian gland secretion (MGS) score and lipid layer thickness measured by LipiView®. To evaluate ocular surface, we measured tear break-up time (BUT) and fluorescein corneal staining score (Oxford scale). Data were presented for baseline and at 2 weeks and 1 month post-treatment. RESULTS: Dry eye symptom (SPEED, OSDI), Meibomian gland function (MGE, MGS), and ocular surface index (BUT, Oxford scale) of patients were significantly improved from baseline to 2 weeks (p < 0.05) and 1 month post-treatment (p < 0.05). In addition, patients with more severe dry eye symptom and Meibomian gland index at baseline examination achieved improvement in mild to moderate MGD (p < 0.05). Improvement of Meibomian gland function (MGE) was associated with improvement of ocular surface index (BUT, Oxford scale) (p < 0.05), but not with improvement of dry eye symptom (SPEED, OSDI) (p > 0.05). There were no significant adverse events during the treatment. CONCLUSIONS: KCL 1100® automated thermodynamic treatment is an effective and safe treatment for MGD. Additionally, KCL 1100® is more effective in patients with moderate dry eye symptom and MGD.

PURPOSE: To analyze related factors of retinopathy of prematurity by comparing between premature twins in which retinopathy developed on one twin. METHODS: A retrospective survey consisting of 13 premature twins in which retinopathy of prematurity (stage 1 or more) developed on one twin was performed. All twins were born in Kosin University Gospel Hospital. The twins were separated into two groups according to whether they had retinopathy of prematurity: the retinopathy of prematurity (ROP) group and non-ROP group. The twins' gestational age, weight, sex, Apgar score, treatments, blood tests, and neonatal complications were investigated. RESULTS: There were no significant differences between the twins except platelet count and aspartate aminotransferase. Platelet count was 191 (±46) ×10³/µL in the ROP group and 240 (±77) ×10³/µL in the non-ROP group, a significant difference (p = 0.046). Aspartate aminotransferase was 36 (±26.6) IU/L in the ROP group and 22 (±5.9) IU/L in the non-ROP group, a significant difference (p = 0.019). CONCLUSIONS: In conclusion, we found platelet count and aspartate aminotransferase to be significant factors related to development of retinopathy of prematurity. It is thought that these factors should be considered when screening for ROP, although a larger prospective study is be needed before the results can be applied in clinical practice.
