RESUMO
OBJECTIVE: Cerebral palsy (CP) is a non-progressive Neurodevelopmental disorder mainly treated using Single-event multilevel surgery (SEMLS). SEMLS contains using a casting method to immobilize the operated limb. However, in the present study, in addition to casting, the bandaging method was also applied. Bandaging is a newer method compared to casting. No study has used bandage for post-surgery immobilization. According to the best knowledge of the authors, no study has compared the outcome of bandage and cast for postoperative immobilization regarding the rehabilitation and quality of life (QoL) in the first and third months following the surgery, within the recovery period, which is associated with consequences like caring, hygiene, transferring, and mobility that affect the spirit and function of children. As a result, we decided to investigate the effect of these methods on the QoL of children the following surgery to treat CP. MATERIALS & METHODS: Following an analytical cross-sectional design, 100 children (aged 4-12 years) were randomly divided into hemiplegic and diplegic CP. The Cerebral Palsy QoL questionnaire (CP QOL-Child) was filled by parents of the participants. Based on the type of administered immobilizer, 80 children were randomly divided into two groups (40 subjects in each group). All subjects were evaluated using a similar questionnaire in the first and third months after surgery. The non-parametric Mann-Whitney test and ANOVA test were used to compare the study groups. RESULTS: The mean ratio of QoL changes, based on the CP QoL-Child questionnaire, was significantly increased in the bandage group during the first month after surgery. However, for the cast group, this parameter was significantly decreased (P<0.001). In the third month after surgery, the mean ratio of QoL changes was significantly increased in both groups, but the difference in the mean ratio of QoL changes between the two methods wasn't significant (P=0.64). CONCLUSION: In the first month after surgery, the bandaging method was more effective than the casting method, but in the third month, the outcomes were similar for both groups.
RESUMO
BACKGROUND & OBJECTIVE: Prostate adenocarcinoma is the most common malignancy in males, and the urothelial bladder carcinoma is also prevalent. The histological characteristic of these two tumors is very similar in high-grade cases, and their differentiation is difficult. This study was performed to compare the immunohistochemistry panel of high-grade prostate adenocarcinomas and high-grade urothelial bladder carcinomas. METHODS: In this cross-sectional study, 36 cases of prostate adenocarcinoma and 36 urothelial bladder carcinoma samples were collected from the pathology department of Shahid Beheshti Hospital in Hamedan. For each sample, expression of Cytokeratin 7, high-molecular-weight cytokeratin and Prostate-specific antigen markers was evaluated by immunohistochemistry. Comparison of expression of these markers in high-grade bladder tumors and prostate tumors was made by SPSS 25 using Chi-square test. RESULTS: In this study, the Cytokeratin 7 positivity was seen in 88.9% of bladder cancer versus 27.8% of prostate cancer samples. High-molecular-weight cytokeratin positive immunoreactivity was noted in 55.6% of bladder cancer and 5.6% of prostate cancer samples. Prostate-specific antigen marker showed positive results in 94.4% of prostate cancer samples, but no positivity was evident in those of bladder cancer. CONCLUSION: A panel of immunohistochemical stains can be used to differentiate high-grade prostate adenocarcinoma from urothelial bladder carcinoma in those cases which are challenging to diagnose.
