Group1:Sulfuric acid (SA), Group 2: PDT (RB), Group 3: Al2O3, Group 4 EYL, respectively. The Ra of PEEK discs was evaluated using the surface profilometer.

A stereo microscope was also used to evaluate the type of breakdown. The data were analyzed using Tukey's test and one-way analysis of variance.Results: The SA treated group exhibited the highest Ra. Nevertheless, the RB specimens activated by PDT treatment had the lowest mean Ra score. The group that received the treatment of SA exhibited the highest average score of SBS. In contrast, specimens treated with PDT and activated by RB exhibited the lowest levels of bond fidelity.

It commonly affects exposed areas. Currently, surgical resection is considered the primary approach for BCC treatment. However, BCC frequently affects exposed facial areas, leading to visible scars after surgery. PDT has garnered increasing recent attention, demonstrating superior efficacy and favorable cosmetic outcomes for superficial BCCs. However, it shows limited treatment effectiveness for deep-seated tumors. Most of the current literature focuses on the combination of surgery and postoperative PDT, while no studies have reported on the use of standard surgical excision with intraoperative margin pathological monitoring and immediate PDT. Therefore, we implemented a treatment protocol combining surgery and immediate PDT. Accordingly, this paper aimed to explore the effectiveness, cosmetic outcomes, and other relevant advantages of this therapeutic approach.Methods: We aimed to evaluate this approach in seven patients with BCC on the nose and ears. Standard surgical excision of skin lesions was performed, with intraoperative frozen section examination of the margins, followed by immediate postoperative PDT for the wounds, and continued periodic PDT during the second phase of wound healing.Results: All seven cases demonstrated significant improvement. The cosmetic rating was 100 % and no cases of recurrence existed among the seven patients.Conclusions: This approach effectively minimized the surgical wound, improved tumor clearance, achieved precise therapeutic effects, and reduced the recurrence rate. Moreover, it produced favorable cosmetic outcomes.","PeriodicalId":94170,"journal":{"name":"Photodiagnosis and photodynamic therapy","volume":" ","pages":"103904"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138178379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optical techniques utilizing the local application of fluorescein dye or fluorescence-guided surgery offer potential for early OSCC detection. The use of fluorescein dye in oral cancer is significantly less, and there is a need to inspect the local application of fluorescein dye in oral cancer patients. Concentration-based investigations of the dye with OSCC patients are essential to ensure accurate fluorescence-guided surgery and screening with fluorescein labeling and to mitigate possible adverse effects. Additionally, analyzing the dye distribution within OSCC tissues can provide insights into their heterogeneity, a critical indicator of malignancy. The present study includes a concentration-based statistical and spectroscopic analysis of fluorescein dye in ex-vivo and in-vivo OSCC patients. In the ex-vivo examination of OSCC tissues, five concentrations (18.66 ± 0.06, 9.51 ± 0.02, 6.38 ± 0.01, 4.80 ± 0.004, and 3.85 ± 0.002 millimolar) are employed for optical analysis. The ex-vivo OSCC tissues are analyzed for multiple statistical parameters at all concentrations, and the results are thoroughly described. Additionally, spectroscopic analysis is conducted on all concentrations for a comprehensive evaluation. Following optical analysis of all five concentrations in the ex-vivo study, two concentrations, 6.38 ± 0.01 and 4.80 ± 0.004 millimolar, are identified as suitable for conducting in-vivo investigations of oral cancer. A detailed spectroscopic and statistical study of OSCC tissues in-vivo has been done using these two concentrations.","PeriodicalId":94170,"journal":{"name":"Photodiagnosis and photodynamic therapy","volume":" ","pages":"103889"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72212477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Visual acuity (VA) optical coherence tomography (OCT) and fundus autofluorescence (FAF) were performed before and after the treatment. The HRPE was identified on OCT as a hyperreflective and dense material at the expense of the RPE that did not exist prior to the treatment. The demographics of the patients as well as the parameters of the STL treatments employed were registered.Results: Seven HRPE cases after STL were identified, observing an incidence of 4.7% (7 out of 149 eyes). The mean age was 52.1 ± 3.6 years, being 6/7 males. The mean number of STL sessions was 1.3 ± 0.5. The mean total fluence applied was 52.2 ± 12.4 J/cm2 (range 35.37 to 76.39 J/cm2), using a duty cycle of 10% in all cases. The HRPE was subfoveal in 6 of the 7 cases. The SRF was resolved in 6 of the 7 patients. The mean VA loss was -14.1 ± 14.3 ETDRS letters.Conclusion: The development of HRPE secondary to STL in CSCR is an uncommon but severe adverse effect, probably related to the excessive energy employed. Further studies are warranted to minimize the incidence and to know the predictors of this complication after STL treatment to optimize the parameters that should be used.","PeriodicalId":94170,"journal":{"name":"Photodiagnosis and photodynamic therapy","volume":" ","pages":"103896"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138178380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are no reports of its application in surgery for rare type II cystic biliary atresia. We report a girl presented with jaundice and light-colored stools. Laboratory tests showed impaired liver function with elevated serum bilirubin and bile acid levels. The abdominal ultrasound and MRCP suggested a common hepatic duct cyst. A diagnosis of choledochal cyst was suspected and biliary atresia could not be excluded. Conservative treatment was unsatisfactory. Laparoscopic exploration with indocyanine green fluorescence was performed on the 38th day of her life, and intraoperative diagnosis of type II CBA was made because the common hepatic duct cyst and its downstream anatomical structures did not show fluorescence. The postoperative bilirubin and bile acid levels decreased significantly and she was discharged two weeks after surgery. This result suggests that indocyanine green can be safely used in laparoscopic surgery for type II CBA, which not only helps in the differential diagnosis of CBA and choledochal cyst, but also confirms bile flow in real time.","PeriodicalId":94170,"journal":{"name":"Photodiagnosis and photodynamic therapy","volume":" ","pages":"103846"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41224283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
