Introduction: In the rehabilitation period following a stroke, rehabilitation therapists must thoroughly evaluate the condition of patients for the purposes of goal-setting and effective training. Postgraduate education in the medical examination of patients after stroke was provided for rehabilitation therapists, and changes in their autonomy during medical examinations were subsequently assessed.
Method: The education consisted mainly of reading case reports about patients who had strokes and learning neurological examination techniques. A total of 35 once-weekly education sessions were provided to rehabilitation therapists working in a convalescent rehabilitation ward. The rehabilitation therapists evaluated their independence with respect to obtaining patient backgrounds, vital signs, physical findings, neurological findings, laboratory results, and basic knowledge of illness at the beginning and end of the education sessions and 6 months after the sessions ended. Each evaluation item was compared according to the time of evaluation.
Results: Rehabilitation therapists’ autonomy over obtaining patient backgrounds, neurological findings, laboratory results, and basic knowledge of illness was greater at the end of the education sessions than at the start of the sessions. Their autonomy over obtaining information in these 4 areas and obtaining physical findings was greater 6 months after the end of the education sessions than at the start of the sessions.
Discussion: We conclude that workplace postgraduate training in the medical examination of patients who have had strokes improves rehabilitation therapists’ autonomy during medical assessments.

OBJECTIVE: In cervical intraepithelial neoplasia (CIN), p16INK4a immunohistochemistry has been reported to be a useful diagnostic biomarker. However, limited information is available about the association between the p16INK4a immunohistochemistry and the outcomes of CIN. Here, we report p16INK4a immunohistochemistry as an effective biomarker to predict the outcomes of CIN. METHODS: p16INK4a immunohistochemistry was performed in patients with CIN from January 2000 to August 2009. Among these patients, we have performed a retrospective analysis of the medical records to evaluate the outcome of CIN 1-2 and performed statistical analysis to determine the correlation between p16INK4a expression and the outcomes. We also performed HPV genotyping and analyzed the relation between the infecting human papillomavirus (HPV) genotype and the outcomes. RESULTS: A total of 244 patients, including 82 with CIN 1, 60 with CIN 2, and 102 with CIN 3, were examined. The rate of p16INK4a overexpression increased with increasing CIN grade, 20.7% for CIN 1, 80.0% for CIN 2, and 89.2% for CIN 3, with significant differences between CIN 1 and CIN 2-3 group. In the 131 CIN 1-2 patients, the progression rate was significantly higher for the patients showing p16INK4a overexpression than for those not showing p16INK4a overexpression (p=0.005); the regression rate was also found to be significantly lower for the patients showing p16INK4a overexpression (p=0.003). High-risk HPV genotypes were detected in 73 patients (73.7%). Both progression and regression rates were not significantly different between the high-risk HPV-positive and HPV-negative groups (p=0.401 and p=0.381, respectively). CONCLUSION: p16INK4a overexpression was correlated with the outcome of CIN 1-2, and p16INK4a is considered to be a superior biomarker for predicting the outcome of CIN 1-2 compared with HPV genotyping.

Objective:
To identify candidate predictors for the prognosis of cervical intraepithelial neoplasia 2 (CIN2) lesions and evaluate the prognostic value of the local immune response.
Methods:
One hundred fifteen CIN2 patients were enrolled. The percentage of p16-, minichromosome maintenance complex component 2- or apolipoprotein B mRNA editing enzyme catalytic subunit 3G (APOBEC3G)-positive cells was determined immunohistochemically. Tumor-infiltrating lymphocytes (TILs) in intertumoral lesions were scored using an automated system. CIN3 disease progression and regression rates were estimated by the Kaplan–Meier method. A case-control study was conducted to screen CIN2 prognostic factors in 10 regression and 10 progression patients. Selected factors were examined in a cohort study to determine their prognostic value for CIN2.
Results:
Among all participants, the cumulative progression and regression rates at 60 months were 0.477 and 0.510, respectively. In the case-control study, p16- and APOBEC3G-positive cells were higher in the progression group (p=0.043, p=0.023). Additionally, CD4+ cell infiltration was enhanced in the regression group (p=0.023). The cohort study revealed a significantly increased progression rate in patients with elevated p16-positive cells (p<0.001), and increased CD4+ TIL infiltration was associated with better regression (p=0.011). Kaplan–Meier analysis according to human papillomavirus (HPV) positivity revealed a greater CIN3 development risk in HPV16-positive patients than in HPV16-negative cases. Finally, multivariate analysis identified HPV16 infection and CD4+ TIL infiltration as independent prognostic factors in CIN2 regression.
Conclusion
CD4+ TIL infiltration in intertumoral lesions was related with CIN2 regression. Our findings suggest CD4+ TIL infiltration may be useful for the triage of CIN2 patients.
