ABSTRACT
PURPOSE: To evaluate long-term outcome after revitrectomy with autologous platelet concentrate (APC) or whole blood (WB) in persistent idiopathic macular hole (MH) after vitrectomy with internal limiting membrane (ILM) peeling. PROCEDURES: Retrospective study of 75 eyes with persistent MH after vitrectomy with ILM peeling and gas. All patients underwent revitrectomy with gas and APC (n = 61) or WB (n = 14). Main outcome measures were anatomical closure rate and postoperative best-corrected visual acuity (BCVA). RESULTS: Closure rate after revitrectomy was 85.2% (52/61) in the APC group and 7.1% (1/14) in the WB group. Median follow-up was 58 (range 3-147) months. Median BCVA (logMAR) in patients with finally closed MHs was 0.4 ± 0.3. Patients with defects of the ellipsoid zone had significantly worse postoperative BCVA. Morphological MH configuration (atrophic or elevated edges) did not correlate with final closure rate. CONCLUSIONS: Revitrectomy with APC and gas is a very effective treatment in persistent MH after vitrectomy with ILM peeling and gas.

The positive prognostic value of HPV-infections in oropharyngeal squamous cell cancer (OSCC) patients has led to the initiation of prospective clinical trials testing the value of treatment de-escalation. It is unclear how to define patients potentially benefiting from de-escalated treatment, whether a positive smoking history impacts survival data and what kind of de-escalation might be best. Here, we investigate the effect of HPV-status, smoking habit and treatment design on overall survival (OS) and progression free survival (PFS) of 126 patients with tonsillar SCC (TSCC) who underwent CO2-laser-surgery and risk adapted adjuvant treatment. HPV-DNA-, HPV-mRNA-, and p16INK4A-expression were analysed and results were correlated to OS and PFS. Factors tested for prognostic value included HPV-status, p16INK4A-protein expression, therapy and smoking habit. Log rank test and p-values ≤0.05 defined significant differences between groups. The highest accuracy of data with highest significance in this study is given when the HPV-RNA-status is considered. Using p16INK4A-expression alone or in combination with HPV-DNA-status, would have misclassified 23 and 7 patients, respectively. Smoking fully abrogates the positive impact of HPV-infection in TSCC on survival. Non-smoking HPV-positive TSCC patients show 10-year OS of 100% and 90.9% PFS when treated with adjuvant RCT. The presented data show that high-precision HPV-detection methods are needed, specifically when treatment decisions are based on the results. Furthermore, smoking habit should be included in all studies and clinical trials testing HPV-associated survival. Adjuvant RCT especially for HPV-positive non-smokers may help to avoid distant failure.
