logistic regression and chi using SPSS program (Windows, version 12.0). During the first 24 hours 87% of the patients experienced pain (NRS 1 to 3: 32%, NRS 4 to 7: 44%, NRS 8 to 10: 11%). For postoperative analgesia, the opioid piritramide (a mu-receptor agonist) was administered to 70% and nonopiod analgesics to 73% of the patients. The probability of experiencing postcraniotomy pain was reduced by 3% for each year of life. Maintenance of anesthesia with sevoflurane increased the probability of suffering from postcraniotomy pain by 147% and the absence of corticosteroids by 119%. Other investigated parameters did not influence pain after craniotomy. This study shows that pain is experienced by the majority of patients after craniotomy, despite conventional pain management, emphasizing the necessity for improved and individualized pain management in this special group of patients.

The overall incidence of PONV within 24 hours after craniotomy was approximately 50%. One possible reason is that intracranial surgeries pose an additional and independent risk factor for vomiting, especially in female patients. Patients undergoing craniotomy should be identified as high-risk patients for PONV.

The incidence of oropharyngeal squamous cell carcinoma (OPSCC) has increased in the past decades due to carcinogenic HPV infection. As this patient group suffers from considerable mortality and treatment morbidity it is important to improve prognostic strategies in OPSCC. Inflammation plays a key role in cancer and the neutrophil-to-lymphocyte ratio (NLR) in blood has been suggested as a prognostic factor for OPSCC. This study aimed to investigate the prognostic impact of NLR on overall survival (OS) and recurrence-free survival (RFS) in a retrospective cohort of 1370 patients. Included patients had pretreatment neutrophil and lymphocyte counts available, as well as a known HPV status. Patients were treated with curative intent according to Danish national guidelines. We stratified patients in groups by NLR < 2, NLR 2–4, or NLR > 4 and analyzed the influence of the NLR tertile on OS and RFS. Kaplan–Meier curves illustrated survival probability in OS and RFS in the general cohort and were stratified by HPV status. We found that an increasing NLR was associated with inferior OS (HR = 1.5 for NLR > 4) and RFS (HR = 1.6 for NLR 2–4; HR = 1.8 for NLR > 4) in multivariable analysis. The Kaplan–Meier curves displayed inferior OS and RFS with an increasing NLR for both HPV+ and HPV− patients. In conclusion, we showed that an increasing NLR is prognostic for a worse outcome of OPSCC independently of HPV status. There are possible uses of NLR in prognostication and treatment de-escalation although further studies are warranted to determine the clinical utility.
