RESUMEN
Purpose: Nasal septoplasty is one of the most common surgical procedures in otorhinolaryngology and optimising both patient selection and the surgery is a challenge. The Nordic countries have similar public healthcare systems and comparable populations in terms of size. Methods: This is a review of studies of outcome and predictors related to septoplasty from Denmark, Finland, Norway and Sweden, published during the last decade. The aim of this review was to identify areas in need of further research to meet the challenges of septoplasty in the Nordic countries with reference to international data. Results: Postoperative patient satisfaction at 6-12 months was reported in around 2/3 of the patients and well in line with international data. Patients with more severe symptoms had a higher chance of improvement. Lack of standardisation in patient selection, surgical methods and skills, and follow up procedures, still makes it difficult to explain the 25% failure rate in septoplasty surgery. Conclusion: This review of the Nordic studies from the last decade shows that septoplasty in general is effective in relieving nasal obstruction. There is a need for studies addressing the standardisation of diagnostic tools and algorithms and the systematic and continuous implementation of follow-up of the surgical results at both departmental and personal level. This includes an awareness of how surgical skills in septoplasty are obtained and maintained.
RESUMEN
With improved understanding of the biology of differentiated thyroid carcinoma its management is evolving. The approach to surgery for the primary tumour and elective nodal surgery is moving from a "one-size-fits-all" recommendation to a more personalised approach based on risk group stratification. With this selective approach to initial surgery, the indications for adjuvant radioactive iodine (RAI) therapy are also changing. This selective approach to adjuvant therapy requires understanding by the entire treatment team of the rationale for RAI, the potential for benefit, the limitations of the evidence, and the potential for side-effects. This review considers the evidence base for the benefits of using RAI in the primary and recurrent setting as well as the side-effects and risks from RAI treatment. By considering the pros and cons of adjuvant therapy we present an oncologic surgical perspective on selection of treatment for patients, both following pre-operative diagnostic biopsy and in the setting of a post-operative diagnosis of malignancy.

BACKGROUND AND AIMS: Additive manufacturing or three-dimensional printing is a novel production methodology for producing patient-specific models, medical aids, tools, and implants. However, the clinical impact of this technology is unknown. In this study, we sought to characterize the clinical adoption of medical additive manufacturing in Finland in 2016-2017. We focused on non-dental usage at university hospitals. MATERIALS AND METHODS: A questionnaire containing five questions was sent by email to all operative, radiologic, and oncologic departments of all university hospitals in Finland. Respondents who reported extensive use of medical additive manufacturing were contacted with additional, personalized questions. RESULTS: Of the 115 questionnaires sent, 58 received answers. Of the responders, 41% identified as non-users, including all general/gastrointestinal (GI) and vascular surgeons, urologists, and gynecologists; 23% identified as experimenters or previous users; and 36% identified as heavy users. Usage was concentrated around the head area by various specialties (neurosurgical, craniomaxillofacial, ear, nose and throat diseases (ENT), plastic surgery). Applications included repair of cranial vault defects and malformations, surgical oncology, trauma, and cleft palate reconstruction. Some routine usage was also reported in orthopedics. In addition to these patient-specific uses, we identified several off-the-shelf medical components that were produced by additive manufacturing, while some important patient-specific components were produced by traditional methodologies such as milling. CONCLUSION: During 2016-2017, medical additive manufacturing in Finland was routinely used at university hospitals for several applications in the head area. Outside of this area, usage was much less common. Future research should include all patient-specific products created by a computer-aided design/manufacture workflow from imaging data, instead of concentrating on the production methodology.

PURPOSE: Late-stage OTSCC is associated with poor overall survival (OS). Non-curative treatment approach aims to improve quality of life and prolong survival of patients deemed incurable. The purpose of this study was to investigate the used non-curative treatment modalities for OTSSC and patient survival. METHODS: All patients diagnosed with OTSCC and treated with non-curative intent at the HUS Helsinki University Hospital (Helsinki, Finland) during the 12-year period of 2005-2016 were included. Survival analysis after the non-curative treatment decision was conducted using the Kaplan-Meier method in this population-based study. RESULTS: Eighty-two patients were identified. A non-curative treatment decision was made at presentation without any previous treatment in 26 patients (7% of all patients diagnosed with OTSCC during the study period). Palliative radiotherapy was administered to 24% of all patients. The average survival time after the non-curative treatment decision was 3.7 months (median 2 and range 0-26). CONCLUSIONS: Due to the short mean survival time after decision for treatment with non-curative intent, and the notable symptom burden in this patient population, a prompt initiation of all non-curative measures is warranted.

BACKGROUND: Osteosarcomas (OS) in the craniomaxillofacial (CMF) region are typically diagnosed at later age than long-bone OS, but they are reported to have better 5-year survival. Curative treatment warrants wide surgical resection, which is often not possible in the CMF region. The purpose of this article is to present a nationwide series of CMF in Finland to discuss the role of surgery. PATIENTS AND METHODS: All 21 CMF OS patients managed in Finland from 1992 to 2009 were included. The mean age was 40 years (range 15-72). Data on patient and tumor characteristics, treatment modalities, and survival were recorded. All patients had a minimum follow-up of 5 years or until death. RESULTS: OS was evenly represented in the mandible and maxillary bones, which together constituted 76% of all sites. Surgery with curative intent was carried out in 20 patients. Clear margins were achieved in only five cases. Eight (40%) of these 20 patients died due to OS, and their average survival time was 1.3 years. Seven (35%) out of the 20 patients received radiotherapy due to close/intralesional surgical margins, and four of them did not develop recurrences during the follow-up. CONCLUSIONS: The results suggest that postoperative radiotherapy may alter the prognosis in CMF OS, particularly in cases with close or intralesional margins. This may increase the survival rates achieved by prompt action in performing radical surgery.

BACKGROUND: To describe a cohort of sinonasal mucosal melanoma (SNMM) patients, and to assess if choice of surgical approach (open versus endoscopic) has impact on survival. METHODOLOGY: Adequate data on clinical presentation, treatment, and recurrence pattern were available for 58 consecutive patients treated for SNMM at the Helsinki University Hospital (HUH) between 1983 and 2016. RESULTS: The 5-year disease-specific survival (DSS) was 27% and overall survival 25% for the whole cohort. The 3-year DSS for patients treated with curative intent with endoscopic surgery was comparable to open surgery (56% and 51%, respectively). Patients with tumours arising from the paranasal sinuses and patients with Stage IV disease had significantly worse prognosis compared with other locations and Stage III patients. All patients who had disease persistence at three months after primary treatment succumbed to SNMM. Post-operative radiotherapy did not affect survival significantly, but a trend towards improved local control was observed. CONCLUSIONS: Local control after endoscopic surgery was comparable to open surgery. Small tumours without local or locoregional spread had improved prognosis, independent of surgical approach. Disease persistence after treatment with curative intent led to death invariably.

BACKGROUND: Head and neck cancers are often diagnosed at a late stage, thus resulting in a generally poor prognosis. This is partly attributable to patients' hesitancy in seeking treatment. However, the length and causes of these patient delays remain relatively unknown. MATERIAL AND METHODS: We included all new head and neck cancer patients treated at our tertiary care center between 2016 and 2017. Using a patient questionnaire, we collected data on patients' symptoms and other factors related to seeking medical care, and recorded both patient- and primary health care-related delays. We then compared the data collected from these patients to patient and tumor characteristics collected from hospital records, and analyzed various causes for delay before a specialist consultation to the Department of Otorhinolaryngology - Head and Neck Surgery. RESULTS: Among the patients (n = 142) in our study, the median patient delay was 35 d with 73% of patients seeking medical care within 3 months. In comparison, the median primary health-care delay was 20 d. Certain symptoms influenced patient delay. Hoarseness and breathing difficulties correlated with longer patient delay while patients with a lump on the neck had a shorter delay. Patient delay was associated with certain tumor-related factors such as the tumor site and the presence of regional metastases, which resulted in shorter patient delay. None of the patient-related factors appeared to impact delay. Important factors influencing primary health-care delay included the initial location visited and whether any follow-up visit was scheduled or not. CONCLUSIONS: Although most patients sought medical advice without a major delay and were adequately referred, we found that long delays existed. Raising awareness of the symptoms of head and neck cancer among general population and health-care providers is probably the best way to get patients to curative treatment without delay.

Standard of care for cancer is commonly a combination of surgery with radiotherapy or chemoradiotherapy. However, in some advanced cancer patients this approach might still remaininefficient and may cause many side effects, including severe complications and even death. Oncolytic viruses exhibit different anti-cancer mechanisms compared with conventional therapies, allowing the possibility for improved effect in cancer therapy. Chemotherapeutics combined with oncolytic viruses exhibit stronger cytotoxic responses and oncolysis. Here, we have investigated the systemic delivery of the oncolytic adenovirus and paclitaxel encapsulated in extracellular vesicles (EV) formulation that, in vitro, significantly increased the transduction ratio and the infectious titer when compared with the virus and paclitaxel alone. We demonstrated that the obtained EV formulation reduced the in vivo tumor growth in animal xenograft model of human lung cancer. Indeed, we found that combined treatment of oncolytic adenovirus and paclitaxel encapsulated in EV has enhanced anticancer effects both in vitro and in vivo in lung cancer models. Transcriptomic comparison carried out on the explanted xenografts from the different treatment groups revealed that only 5.3% of the differentially expressed genes were overlapping indicating that a de novo genetic program is triggered by the presence of the encapsulated paclitaxel: this novel genetic program might be responsible of the observed enhanced antitumor effect. Our work provides a promising approach combining anticancer drugs and viral therapies by intravenous EV delivery as a strategy for the lung cancer treatment.

BACKGROUND: Studies on palliative care of head and neck cancer (HNC) patients are scarce although the affected patient population is quite large. OBJECTIVE: To evaluate the role of a specialised palliative-care pathway of HNC patients. PATIENTS AND METHODS: Data on all HNC patients who were treated at the Helsinki University Hospital Palliative Care Center during 1 year were retrospectively reviewed. The analysis comprised 60 patients (49 males; mean age 67 years; range 28-88). All patients had a minimum follow-up of 1 year or until death. RESULTS: Fifty-nine (98%) out of the 60 patients died during the follow-up period. Median survival after diagnosis was 11 months (range 3 weeks-11.9 years) and after withholding disease-specific therapies 3 months (range 0-16). Thirty-three (55%) patients received palliative radiotherapy, 27 (45%) had PEG tube and 17 (28%) tracheostomy. Thirty-seven (66%) patients visited an emergency department (ED) (median 1.3 visits; range 0-6) and 21 (35%) were hospitalised at the university hospital during the palliative period. The most common severe complications were infection (also the most common reason for ED visits and hospitalisation), bleeding (four massive airway bleedings with one death), delirium and airway obstruction (one emergency tracheostomy). Twelve (35%) out of the 34 patients who were referred to specialised home care died at home as compared with three (12%) out of the 26 patients not supported by a specialised home-care team. CONCLUSIONS: Severe complications leading to an emergency unit visit and hospitalisation are common among HNC patients in their relatively short palliative period reflecting the need for early-integrated palliative care. Collaboration with a specialised palliative home-care team seems to increase end-of-life care at home.

BACKGROUND AND AIMS: Prosthetic mask restoration of the donor face is essential in current facial transplant protocols. The aim was to develop a new three-dimensional (3D) printing (additive manufacturing; AM) process for the production of a donor face mask that fulfilled the requirements for facial restoration after facial harvest. MATERIALS AND METHODS: A digital image of a single test person's face was obtained in a standardized setting and subjected to three different image processing techniques. These data were used for the 3D modeling and printing of a donor face mask. The process was also tested in a cadaver setting and ultimately used clinically in a donor patient after facial allograft harvest. RESULTS: and Conclusions: All the three developed and tested techniques enabled the 3D printing of a custom-made face mask in a timely manner that is almost an exact replica of the donor patient's face. This technique was successfully used in a facial allotransplantation donor patient.

BACKGROUND: Although new therapeutic approaches for burn treatment have made progress, there is still need for better methods to enhance wound healing and recovery especially in severely burned patients. Nanofibrillar cellulose (NFC) has gained attention due to its renewable nature, good biocompatibility and excellent physical properties that are of importance for a range of applications in pharmaceutical and biomedical fields. In the present study, we investigated the potential of a wood based NFC wound dressing in a clinical trial on burn patients. Previously, we have investigated NFC as a topical functionalized wound dressing that contributes to improve wound healing in mice. METHODS: Wood based NFC wound dressing was tested in split-thickness skin graft donor site treatment for nine burn patients in clinical trials at Helsinki Burn Centre. NFC dressing was applied to split thickness skin graft donor sites. The dressing gradually dehydrated and attached to donor site during the first days. During the clinical trials, physical and mechanical properties of NFC wound dressing were optimized by changing its composition. From patient 5 forward, NFC dressing was compared to commercial lactocapromer dressing, Suprathel® (PMI Polymedics, Germany). RESULTS: Epithelialization of the NFC dressing-covered donor site was faster in comparison to Suprathel®. Healthy epithelialized skin was revealed under the detached NFC dressing. NFC dressing self-detached after 11-21days for patients 1-9, while Suprathel® self-detached after 16-28days for patients 5-9. In comparison studies with patients 5-9, NFC dressing self-detached on average 4days earlier compared with Suprathel®. Lower NFC content in the material was evaluated to influence the enhanced pliability of the dressing and attachment to the wound bed. No allergic reaction or inflammatory response to NFC was observed. NFC dressing did not cause more pain for patients than the traditional methods to treat the skin graft donor sites. CONCLUSION: Based on the preliminary clinical data, NFC dressing seems to be promising for skin graft donor site treatment since it is biocompatible, attaches easily to wound bed, and remains in place until donor site has renewed. It also detaches from the epithelialized skin by itself.

The objective of the study was to investigate the nationwide occurrence of sinonasal pleomorphic adenoma in Finland. A retrospective study was conducted at The Departments of Otorhinolaryngology-Head and Neck Surgery, and Pathology at the five university hospitals in Finland. Data were obtained by searching for sinonasal pleomorphic adenoma cases in the clinical and histopathological registries at these institutions for the past two to four decades. All patients who had had a histologically proven pleomorphic adenoma in the sinonasal area were included as participants. Ten cases with pleomorphic adenoma of the nasal cavity were found. The majority of these tumours originated in the septum, and there were no malignant transformations. Pleomorphic adenomas of the nasal cavity were found to be extremely rare in this nationwide investigation.

BACKGROUND: Intracranial complications of paranasal sinusitis have become rare due to widespread and early use of antibiotics. Potentially life-threatening intracranial complications of sinusitis include subdural empyema, epidural and intracerebral abscess, meningitis, and sinus thrombosis. Patients with intracranial complication of sinusitis can present without neurological signs, which may delay diagnosis and correct treatment. AIMS: Our aim was to evaluate the diagnostics, treatment, and outcome of sinusitis-related intracranial infections at our tertiary referral hospital with a catchment area of 1.9 million people. MATERIALS AND METHODS: We retrospectively collected data on all patients diagnosed and treated with an intracranial infection at the Helsinki University Hospital, Helsinki, Finland, during a 10-year period between 2003 and 2013. RESULTS: Six patients were diagnosed to have a sinusitis-related intracranial infection. Four patients had an epidural abscess, one both an epidural abscess and a subdural empyema and one a subdural empyema. The most common presenting complaint was headache (100%) followed by fever (83%), vomiting (50%), nasal congestion (50%), forehead lump (34%), and neck stiffness (17%). All patients were managed surgically. Most (83%) patients recovered to premorbid state without neurological sequelae. One patient died intraoperatively. CONCLUSION: Patients with a sinusitis-related intracranial suppuration typically present with signs of raised intracranial pressure rather than signs of sinusitis. Most are likely to need neurosurgical intervention and evacuation of the abscess without delay.
RESUMEN
Adenoid cystic carcinoma (ACC) of the salivary glands has a poor long-term prognosis and high metastatic rate. Toll-like receptors (TLRs) have been related to tumour progression but have also tumour growth-inhibiting responses. To the best of our knowledge, they have not been studied previously in ACC. We studied the immunoexpression of TLR 5 and 7 in ACC of the major salivary glands. From a cohort of 54 patients with ACC of the major salivary glands treated at the Department of Otorhinolaryngology-Head and Neck Surgery, Helsinki University Hospital, Helsinki, Finland in 1974-2009, there were 34 primary tumours and six metastases available for immunohistochemical analysis. Immunohistochemical expression of TLR 5 and 7 were correlated to clinicopathological findings and patient survival. Both TLR 5 and 7 were expressed in ACCs and their metastases, mostly on the cell membranes. The expression was heterogeneous in individual tumours. TLR 5 was expressed less in male samples, and TLR 7 had lower expression in ACCs with solid growth pattern. No correlation with survival was found. In the normal salivary gland, the TLR 5 and 7 expression was mainly negative. Both TLR 5 and 7 are expressed in salivary adenoid cystic carcinoma on the cell membranes as well as in cytoplasm.
