Glioma grade and post-neurosurgical meningitis risk.

BACKGROUND: Post-neurosurgical meningitis (PNM) constitutes a grave complication associated with substantial morbidity and mortality. This study aimed to determine the risk factors predisposing patients to PNM following surgery for low- and high-grade gliomas. METHODS: We conducted a retrospective analysis encompassing all patients who underwent glioma surgery involving craniotomy at Turku University Hospital, Turku, Finland, between 2011 and 2018. Inclusion criteria for PNM were defined as follows: (1) Positive cerebrospinal fluid (CSF) culture, (2) CSF leukocyte count ≥ 250 × 106/L with granulocyte percentage ≥ 50%, or (3) CSF lactate concentration ≥ 4 mmol/L, detected after glioma surgery. Glioma grades 3-4 were classified as high-grade (n = 261), while grades 1-2 were designated as low-grade (n = 84). RESULTS: Among the 345 patients included in this study, PNM developed in 7% (n = 25) of cases. The median time interval between glioma surgery and diagnosis of PNM was 12 days. Positive CSF cultures were observed in 7 (28%) PNM cases, with identified pathogens encompassing Staphylococcus epidermidis (3), Staphylococcus aureus (2), Enterobacter cloacae (1), and Pseudomonas aeruginosa (1). The PNM group exhibited a higher incidence of reoperations (52% vs. 18%, p < 0.001) and revision surgery (40% vs. 6%, p < 0.001) in comparison to patients without PNM. Multivariable analysis revealed that reoperation (OR 2.63, 95% CI 1.04-6.67) and revision surgery (OR 7.08, 95% CI 2.55-19.70) were significantly associated with PNM, while glioma grade (high-grade vs. low-grade glioma, OR 0.81, 95% CI 0.30-2.22) showed no significant association. CONCLUSIONS: The PNM rate following glioma surgery was 7%. Patients requiring reoperation and revision surgery were at elevated risk for PNM. Glioma grade did not exhibit a direct link with PNM; however, the presence of low-grade gliomas may indirectly heighten the PNM risk through an increased likelihood of future reoperations. These findings underscore the importance of meticulous post-operative care and infection prevention measures in glioma surgeries.

Balloon Eustachian Tuboplasty-A Feasible Double-Blinded Sham Surgery Randomized Clinical Trial Protocol to Study Efficacy.

INTRODUCTION: Balloon Eustachian tuboplasty (BET) is used to treat obstructive Eustachian tube dysfunction (OETD) and recurrent otitis media with effusion (OME). However, there are no indisputable evidence of its efficacy. Here, we present a multicenter, double-blinded, randomized, placebo-controlled trial (MDRCT) design to evaluate the efficacy of BET, and the results of a pilot trial with 3- and 12-months' follow-up. MATERIAL AND METHODS: This was a prospective MDRCT. For a pilot study, OETD (n = 10) and OME (n = 5) patients were recruited and followed. Detailed inclusion and exclusion criteria were used. Participants were randomized at beginning of the operation to active or sham surgery. All procedures were performed under local anesthesia. Controls were performed in double-blinded manner (both patient and physician), at 3 and 12 months after the procedure. RESULTS: Altogether, 20 ears were treated and followed for 12 months, including 14 active BETs and 6 sham surgeries. Both the active and sham surgery were performed under local anesthesia without problems or deviations from the protocol. There were no differences in the preoperative symptoms (ETDQ-7) or objective measures (tympanometry, Valsalva and Toynbee maneuvers, tubomanometry, Eustachian tube score) between active and sham surgery arms. During follow-up, we noticed largely similar reduction in subjective symptoms and improvement in Eustachian tube score both in active and sham surgery arms. CONCLUSIONS: The pilot study demonstrates that our MDRCT protocol is feasible, and that blinded RCTs are dearly needed to objectively measure the efficacy of BET.

Finnish paediatric study found a low incidence of bacterial meningitis from 2011 to 2018 but a substantial proportion of nosocomial meningitis.

AIM: This study examined the predisposing factors, clinical picture, bacterial aetiology and clinical outcomes of infants and children with bacterial meningitis (BM). METHODS: The medical records of patients under 16 years of age, treated by Turku University Hospital, Finland, from 2011 to 2018, were screened for meningitis using the International Classification of Diseases, Tenth Revision codes. Patients were included if bacteria were detected in cerebrospinal fluid (CSF) or other predefined laboratory variables indicated BM, despite CSF testing negative for bacteria. The Glasgow Outcome Scale (GOS) was used to determine outcomes. RESULTS: We identified 37 children with BM: 22 infants aged 0-89 days and 15 children aged 90 days to 15 years. The overall incidence was approximately 5.7/100 000/year. Nosocomial meningitis was documented in 51%. Bacterial growth was detected in the CSF or blood cultures of the majority of patients (57%). Escherichia coli (14%), group B streptococcus (11%) and Streptococcus pneumoniae (8%) were the most common pathogens. There were 14% of patients with unfavourable outcomes, namely GOS scores of 1-4, but no deaths. CONCLUSION: The incidence of paediatric BM was low during the study period, but the proportion of nosocomial meningitis was substantial. The frequency of unfavourable long-term outcomes was relatively low.

Bacterial meningitis in adults: a retrospective study among 148 patients in an 8-year period in a university hospital, Finland.

BACKGROUND: Bacterial meningitis (BM) causes significant morbidity and mortality. We investigated predisposing factors, clinical characteristics, spectrum of etiological bacteria, and clinical outcome of community-acquired and nosocomial BM. METHODS: In this retrospective study we analyzed data of 148 adults (age > 16 years) with BM treated in Turku University Hospital, Southwestern Finland, from 2011 to 2018. Besides culture- or polymerase chain reaction (PCR)-positive cases we also included culture-negative cases with laboratory parameters strongly suggestive of BM and those with meningitis-related findings in imaging. We used Glasgow Outcome Scale (GOS) score 1-4 to determine unfavorable outcome. RESULTS: The median age of patients was 57 years and 48.6% were male. Cerebrospinal fluid (CSF) culture for bacteria showed positivity in 50 (33.8%) cases, although pre-diagnostic antibiotic use was frequent (85, 57.4%). The most common pathogens in CSF culture were Streptococcus pneumoniae (11, 7.4%), Staphylococcus epidermidis (7, 4.7%), Staphylococcus aureus (6, 4.1%) and Neisseria meningitidis (6, 4.1%). Thirty-nine patients (26.4%) presented with the triad of fever, headache, and neck stiffness. A neurosurgical procedure or an acute cerebral incident prior BM was recorded in 74 patients (50%). Most of the patients had nosocomial BM (82, 55.4%) and the rest (66, 44.6%) community-acquired BM. Ceftriaxone and vancomycin were the most used antibiotics. Causative pathogens had resistances against the following antibiotics: cefuroxime with a frequency of 6.8%, ampicillin (6.1%), and tetracycline (6.1%). The case fatality rate was 8.8% and the additional likelihood of unfavorable outcome 40.5%. Headache, decreased general condition, head computed tomography (CT) and magnetic resonance imaging (MRI), hypertension, altered mental status, confusion, operative treatment, neurological symptoms, pre-diagnostic antibiotic use and oral antibiotics on discharge were associated with unfavorable outcome. CONCLUSIONS: The number of cases with nosocomial BM was surprisingly high and should be further investigated. The usage of pre-diagnostic antibiotics was also quite high. Headache was associated with unfavorable outcome. The frequency of unfavorable outcome of BM was 40.5%, although mortality in our patients was lower than in most previous studies.

Patient injuries from tonsil and adenoid surgery in Finland.

Objectives: The aims of this national register-based study were to examine patient injury claims related to tonsil and adenoid surgery injuries and to compare the frequency of claims between tonsillectomies and tonsillotomies in Finland. Methods: We analyzed the complaints related to tonsil and adenoid surgery received by the Finnish Patient Insurance Center (PIC) between the years 2000 and 2019. One hundred seventy-two cases were included in the analysis. The annual surgery rates between the years 2000 and 2018 were acquired from the Finnish Institute for Health and Welfare. Results: During the years 2000 to 2018, a total of 292,679 patients had tonsil and/or adenoid surgery nationwide. For tonsil or adenoid surgeries, the national average was 5.3 cases and 1.8 cases per 10,000, respectively, resulting in patient injury claims and compensations. A total of 33.1% of the claims regarding tonsil or adenoid surgery processed by the PIC were compensated. Most of the claims were made after a tonsillectomy (87.8%), and few were made after a tonsillotomy (1.7%). Seven deaths were recorded. Conclusion: Patient injuries from tonsil and adenoid surgeries were mostly related to traditional extracapsular tonsillectomies. Most surgeries, along with most complications, involved specialists, who performed routine operations in high-volume centers. Surgeries for acute or recurrent infections resulted in more claims. Severe complications arising from tonsil and adenoid surgeries were rare. Level of Evidence: 4.

Intracapsular tonsillectomy in the treatment of recurrent and chronic tonsillitis in adults: a protocol of a prospective, single-blinded, randomised study with a 5-year follow-up (the FINITE trial).

INTRODUCTION: The standard surgical treatment for recurrent or chronic tonsillitis is extracapsular tonsillectomy. Recent studies show that intracapsular tonsillectomy has the potential to reduce the postoperative morbidity of patients undergoing tonsil surgery. The Finnish Intracapsular Tonsillectomy (FINITE) trial aims to provide level I evidence to support the hypothesis that the recovery time from tonsil surgery can be reduced with intracapsular tonsillectomy. Additionally, from this trial, major benefits in quality of life, reduction of postoperative complications, treatment costs and throat symptoms might be gained. METHODS AND ANALYSIS: The FINITE trial is a prospective, randomised, controlled, patient-blinded, three-arm clinical trial. It is designed to compare three different surgical methods being extracapsular monopolar tonsillectomy versus intracapsular microdebrider tonsillectomy versus intracapsular coblation tonsillectomy in the treatment of adult patients (16-65 years) suffering from recurrent or chronic tonsillitis. The study started in September 2019, and patients will be enrolled until a maximum of 200 patients are randomised. Currently, we are in the middle of the study with 125 patients enrolled as of 28 February 2022 and data collection is scheduled to be completed totally by December 2027. The primary endpoint of the study will be the recovery time from surgery. Secondary endpoints will be the postoperative pain scores and the use of analgesics during the first 3 weeks of recovery, postoperative haemorrhage, quality of life, tonsillar remnants, need for revision surgery, throat symptoms, treatment costs and sick leave. A follow-up by a questionnaire at 1-21 days and at 1, 6, 24 and 60 months will be conducted with a follow-up visit at the 6-month time point. ETHICS AND DISSEMINATION: Ethical approval was obtained from the Medical Ethics Committee of the Hospital District of Southwest Finland (reference number 29/1801/2019). Results will be made publicly available in peer-reviewed scientific journals. TRIAL REGISTRATION NUMBER: NCT03654742.

Hearing impairment in Angolan children with acute bacterial meningitis with and without otitis media.

AIM: Bacterial meningitis (BM) is a common cause of hearing loss in childhood. Our aim was to investigate bacterial aetiology, hearing impairment and outcome in childhood BM with vs. without otitis media (OM) in Angola. METHODS: Hearing was tested by auditory brainstem response in 391 (76%) children with confirmed BM. The bacteria identified from the ear discharge were compared to those from cerebrospinal fluid (CSF). The hearing findings were compared among children with vs. without OM on days 1 and 7 of hospitalization, and at follow-ups of 1, 3 and 6 month(s). RESULTS: No correlation was found in bacteriology between the ear discharge and CSF. On day 7 in hospital, hearing impairment (>40 dB) was common, regardless of whether concomitant OM or not (in 27% vs. 30%, respectively). Any hearing deficit on day 7 was associated with a higher risk of complicated or fatal clinical course (OR 2.76, CI95% 1.43-5.29, p = 0.002). CONCLUSION: No significant difference prevailed in hearing thresholds between children with or without OM in hospital on day 7 or at later follow-ups. Any hearing impairment during hospital stay associated with a higher risk for complicated clinical course or death.

Treatment of sleep apnoea with tonsillectomy: a retrospective analysis using long-term follow-up data.

PURPOSE: This single-group, retrospective, pre-test-post-test study was performed to examine clinical outcomes in treating obstructive sleep apnoea (OSA) with tonsillectomy alone and had the longest follow-up periods to date. METHODS: We analysed 151 tonsillectomies in our district between the years 2004 and 2018 that had either sleep apnoea or snoring listed as a diagnosis. Twenty-one patients met our criteria and were included. Patient records were analysed for home sleep apnoea test and Epworth Sleepiness Scale (ESS) scores. RESULTS: We defined success as a > 50% reduction of the Apnoea-Hypopnea Index (AHI) and a total AHI of < 20 post-surgery. The averages before surgery were an AHI of 22.3 and an ESS of 7.22. The success rate was 47.6% after tonsillectomy as the sole treatment for obstructive sleep apnoea in our adult population. Eleven patients were non-responders. The average ESS score reduction was 0.69 and did not reach statistical significance. With follow-up times ranging from 1.8 to 171 months, this study had the longest follow-up period compared to other existing studies. No patient with a follow-up longer than one year was a responder. CONCLUSION: Our results support that tonsillectomy is an effective treatment for obstructive sleep apnoea in adults with tonsillar hypertrophy. With less severe OSA than those reported on previously, our patients also had less severe daytime sleepiness before surgery, and daytime sleepiness score reductions did not reach statistical significance. In the future, long-term results should be further analysed.

Ear canal and middle-ear tumors: a single-institution series of 87 patients.

BACKGROUND: Ear canal and middle ear tumors are rare and exhibit variability in histology and clinical manifestation. Surgical resection remains the treatment of choice, but individualized approach is needed to preserve function when possible. AIMS/OBJECTIVES: To review the management and outcome of ear canal and middle ear tumors at an academic referral center. MATERIALS AND METHODS: Helsinki University Hospital (HUS) patient files were searched for clinically and histologically confirmed ear canal and middle ear tumors over a 14-year period. The minimum follow-up time was 2 years. RESULTS: Eighty-seven patients with 88 tumors were identified. There were 20 (23%) benign external auditory canal (EAC), 36 (41%) benign middle ear space (MES), 29 (33%) malignant EAC, and 3 (3%) malignant MES tumors. Most (92%) tumors were managed with primary resection. Thirty-five percent of the operatively managed patients had a residual or a recurrent tumor. CONCLUSIONS AND SIGNIFICANCE: EAC and MES tumors show great diagnostic and histologic heterogeneity with need for individualized investigative and treatment approaches. In benign tumors, we advocate aggressive local surgical control without sacrificing vital structures. In malignant tumors, we recommend local surgical control with or without adjunct RT.

Challenging Management of Plexiform Schwannoma and Plexiform Neurofibroma.

ABSTRACT: Plexiform variants of neurofibromas and schwannomas are rare and typically arise in superficial soft tissues in the head and neck region. The treatment of these tumors is challenging and no generally accepted guidelines exist for their optimal management. The purpose of this study was to review the management and longterm prognosis of head and neck plexiform neurofibromas and schwannomas at 2 tertiary care academic hospitals in Finland over a 31-year period. The pathology files were searched for plexiform neurofibromas and schwannomas between the years 1990 and 2020. The case notes were reviewed for full management details. Two plexiform schwannomas and 6 plexiform neurofibromas were identified. Five of the 6 plexiform neurofibromas were managed operatively. All patients with a surgically managed plexiform neurofibroma underwent multiple operations. Sclerotherapy abolished 1 patient's cutaneous plexiform neurofibromas. The management of plexiform neurofibromas and plexiform schwannomas remains challenging. Sclerotherapy may offer a promising management option for cutaneous plexiform neurofibromas.

Evaluation of pure-tone audiometric protocols in vestibular schwannoma screening.

The objective was to evaluate the pure-tone audiogram-based screening protocols in VS diagnostics. We retrospectively analyzed presenting symptoms, pure tone audiometry and MRI finding from 246 VS patients and 442 controls were collected to test screening protocols (AAO-HNS, AMCLASS-A/B, Charing Cross, Cueva, DOH, Nashville, Oxford, Rule3000, Schlauch, Seattle, Sunderland) for sensitivity and specificity. Results were pooled with data from five other studies, and analysis of sensitivity, specificity and positive likelihood ratio (LR+) for each protocol was performed. Our results show that protocols with significantly higher sensitivity (AMCLASS-A/B, Nashville) show also significantly lowest specificity, and tend to have low association (positive likelihood ratio, LR+) to the VS. The highest LR+ was found for protocols AAO-HNS, Rule3000 and Seattle. In conclusions, knowing their properties, screening protocols are simple decision-making tools in VS diagnostic. To use the advantage of the highest sensitivity, protocols AMCLASS-A + B or Nashville can be of choice. For more reasonable approach, applying the protocols with high LR+ (AAO-HNS, Rule3000, Seattle) may reduce the overall number of MRI scans at expense of only few primarily undiagnosed VS.

Development of otology specific outcome measure: Ear Outcome Survey-16 (EOS-16).

PURPOSE: An important outcome measure of patient care is the impact on the patient's health-related quality of life (HRQoL). Current ear-specific HRQoL instruments are designed for one diagnosis and emphasize different subdivisions such as symptoms, hearing problems, psychosocial impact, and the need for care. The optimal length of the recall period has not been studied. For these reasons, a new survey is needed that would cover most chronic ear diseases. METHODS: A preliminary 24-item survey (EOS-24) was created. Untreated adult patients (included n = 186) with one of seven different chronic otologic conditions from all university hospitals in Finland were recruited to respond to EOS-24 and the 15D general HRQoL instrument. The recruiting otologists evaluated the severity of the disease and the disability caused by it. A control group was recruited. Based on the patients' responses in different diagnosis groups, the items were reduced according to pre-defined criteria. The resulting survey was validated using a thorough statistical analysis. RESULTS: The relevance and necessity of the original 24 items were thoroughly investigated, leading to the exclusion of 8 items and the modification of 1. The remaining 16 items were well-balanced between subdivisions and were useful in all seven diagnosis groups, thus constituting the final instrument, EOS-16. The most suitable recall period was three months. CONCLUSIONS: EOS-16 has been created according to the HRQoL survey guidelines with a versatile nationwide patient population. The survey has been validated and can be used for a wide range of chronic ear diseases as a HRQoL instrument.

Otitis Media-associated Bacterial Meningitis in Children in a Low-income Country.

BACKGROUND: Otitis media (OM) is a common childhood infection that may result in bacterial meningitis (BM). However, OM-associated BM remains poorly characterized. We aimed to study the occurrence, clinical presentation and outcome of this type of childhood BM in Luanda, Angola. METHODS: Five hundred twelve children from our previous clinical BM trial, with the ear meticulously examined, were analyzed whether they had or not OM, and according to their age, ≤12 month old and >12 month old. Prospectively collected clinical data, laboratory test results and outcome for these groups were assessed. RESULTS: Sixty-two children (12%) had OM-associated BM, of whom 39 had otorrhea. Ear discharge was more common in older children (median age 45 months old vs. 12 months old; P < 0.001). Children with OM often showed an additional infectious focus (n = 20, 32% vs. n = 82, 18%; P = 0.016), were dehydrated (n = 16, 26% vs. n = 66, 15%; P = 0.04), and showed higher odds of complicated clinical course or death (odds ratios 2.27, 95% CI: 1.004-5.15, P = 0.049) compared with children without OM. The >12-month-old children with OM often arrived in poor clinical condition with coma and/or ptosis. Otorrhea was associated with HIV positivity. Infants with otorrhea frequently lived under poor socioeconomic conditions. CONCLUSIONS: Children with OM-associated BM were prone to many problems, such as being especially ill at presentation, undergoing a difficult clinical course and showing a higher risk of complicated or fatal outcome. HIV infection and malnutrition were common in children with otorrhea, which was also associated with low socioeconomic status.

Balloon Eustachian Tuboplasty: Systematic Review of Long-term Outcomes and Proposed Indications.

Balloon Eustachian tuboplasty (BET) aims to improve the function of the Eustachian tube (ET). The objective of this study was to review the long-term outcome of BET and present the process and results of outlining indications for BET by the Finnish Otosurgical Society. The literature review is based on a database search performed in May 2017. The search resulted in 100 individual articles, which were screened for relevance. Five articles fulfilled the inclusion criteria (follow-up ≥12 months). Five additional articles (follow-up, 6-11 months) were analyzed to obtain supportive information. The proposed BET indications were constituted in the 2016 annual meeting of the Finnish Otosurgical Society. The workshop included a review of the Eustachian tube physiology, middle ear aeration mechanisms, and BET outcome studies. Thereafter, the members of the Society first voted and then discussed 14 cases in order to conclude whether BET was indicated in each case, and subsequently, a consensus statement on the indications for BET was outlined. The long-term follow-up studies were heterogeneous regarding the Eustachian tube dysfunction (ETD) definition, patient selection, follow-up duration, additional treatments, and outcome measures. The current, but limited, evidence suggests that BET is effective in the long-term. However, more long-term studies with uniform criteria and outcome measures as well as placebo-controlled studies are needed. The proposed indications for BET by the Finnish Otosurgical Society include chronic bothersome symptoms referring to ETD, ETD-related symptoms when pressure changes rapidly, or recurring serous otitis media. With the current evidence, we suggest treating only adults with BET.

Patient satisfaction in the long-term effects of Eustachian tube balloon dilation is encouraging.

OBJECT: To investigate the long-term effects of balloon Eustachian tuboplasty (BET) from patient's perspective and to discover which symptoms of Eustachian tube dysfunction (ETD) benefit the most from BET. METHOD: We designed a retrospective postal questionnaire based on the seven-item ETD questionnaire (ETDQ-7). Our questionnaire covered the severity of present ETD symptoms in comparison with the preoperative situation, the severity of current overall ear symptoms, and possible surgical interventions after BET. Forty-six patients treated in our institution between 2011 and 2013 fulfilled the inclusion criteria and 74% (34 patients; total 52 ears treated with BET) returned the questionnaire with a mean follow-up time of 3.1 years (range 1.8-4.6 years). RESULTS: Pain in the ears, feeling of pressure in the ears, and feeling that ears are clogged had reduced in 75% of the ears that suffered from these symptoms preoperatively. Seventy-seven percent of all the responders felt that their overall ear symptoms were reduced. Altogether, 82% of all the patients stated that they would undergo BET again if their ear symptoms returned to the preoperative level. CONCLUSION: Patient satisfaction in the long-term effects of BET is encouraging. These results may help clinicians in preoperative patient selection and counselling.

Balloon Eustachian tuboplasty under local anesthesia: Is it feasible?

OBJECTIVE: To study whether balloon Eustachian tuboplasty (BET) is a feasible and safe procedure under local anesthesia. STUDY DESIGN: Prospective multicenter case-control study. METHODS: Patients undergoing either BET (n = 13) or endoscopic sinus surgery (ESS) (n = 12) under local anesthesia, with the possibility of sedation and analgesia, were monitored during the procedure and recovery period for possible adverse effects. After the procedure, the patients responded to a questionnaire assessing their experience. RESULTS: No adverse effects were detected in the BET group. Patients in the BET group reported similar Visual Analog Scale scores for pain during the operation as the ESS group (5.0 ± 0.7 vs. 3.2 ± 0.7, mean ± standard error of the mean). However, patients in the BET group experienced more discomfort (4.2 ± 0.6 vs. 2.5 ± 0.3, respectively, P = 0.049). Seventy-seven and 92% of the patients in the BET and ESS groups, respectively, considered the anesthesia and pain relief to be sufficient. Patients from both the BET and ESS groups were almost devoid of pain 1 to 2 hours postoperatively (0.8 ± 0.2 and 1.4 ± 0.3, respectively). In total, 12 of 13 patients in the BET group, and all 12 patients in the ESS group, would choose local anesthesia with sedation and analgesia if they needed to undergo the same procedure again. CONCLUSION: BET is a safe and feasible procedure under monitored anesthesia care, including local anesthesia along with sedation and analgesia. There is need for further methodological improvement to reduce pain and discomfort during the operation. LEVEL OF EVIDENCE: 4. Laryngoscope, 127:1021-1025, 2017.

Otogenic Intracranial Abscesses, Our Experience Over the Last Four Decades.

OBJECTIVE: To evaluate the predisposing factors for otogenic intracranial abscesses, assess their changes over time, and analyze how they differ from those due to other causes. MATERIALS AND METHODS: The medical records of all patients treated for otogenic intracranial abscesses, between 1970 and 2012 at a tertiary referral center, were retrospectively analyzed. The analysis included patient demographics, clinical characteristics, causative pathogens, treatments, outcomes, and comparisons of otogenic and non-otogenic intracranial abscesses. RESULTS: Of all intracranial abscesses, 11% (n=18) were otogenic. In the 1970s, otogenic infections were a common predisposing factor for intracranial abscess; but within our study period, the incidence of otogenic intracranial abscesses decreased. Most (94%) otogenic cases were due to chronic suppurative otitis media and 78% were associated with cholesteatoma. Most patients (94%) had ear symptoms. The most common presenting symptoms were discharge from the infected ear (50%), headache (39%), neurological symptoms (28%), and fever (17%). The most common pathogens belonged to Streptococcus spp. (33%), Gram-negative enteric bacteria (22%), and Bacteroides spp. (11%). Neurosurgery was performed on all patients, 69% of which were prior to a later ear surgery. Surgery of the affected ear was performed on 14 patients (78%). A favorable recovery was typical (78%); however, one patient died. CONCLUSION: Otogenic intracranial abscesses were most commonly due to a chronic ear infection with cholesteatoma. Ear symptoms and Gram-negative enteric bacteria were more common among patients with otogenic than non-otogenic intracranial abscesses.

Jugulotympanic paragangliomas in southern Finland: a 40-year experience suggests individualized surgical management.

Treatment of jugulotympanic paragangliomas (JTPGLs) remains challenging with no clear guidelines for management or follow-up. The aim of this retrospective case-note study was to assess long-term results of operatively and conservatively managed JTPGLs between years 1974-2013. A total of 36 patients with JTPGLs were identified. Clinical characteristics and management outcomes of patients were reviewed. Data were extracted on demographics, symptoms, timing of diagnosis, tumor location and size, embolization, and management, including pre- and post-operative imaging, analysis of operative techniques, and follow-up. Pulsatile tinnitus and hearing loss were the most common presenting symptoms. Thirty-four (94 %) patients were treated with primary surgical therapy and two (6 %) with radiotherapy. The surgical approaches included endaural approach for Fisch Class A tumors and a variety of approaches for Fisch Class B-D tumors with an increasing predilection for function-preserving surgery. Eight (24 %) patients received subtotal resection. Five (15 %) patients had a local recurrence within 10 years after primary surgery. Two (6 %) patients suffered a permanent cranial nerve (CN) deficit after primary surgery. We advocate radical surgery when tumor resection is possible without compromising CNs. Function-preserving surgery with at least a 10-year follow-up for Fisch Class B-D tumors should be considered if CNs are in danger.

Severe Acute Otitis Media and Acute Mastoiditis in Adults.

OBJECTIVE: To evaluate and compare clinical and microbiological findings in adults hospitalized for acute otitis media (AOM) or mastoid infections (acute or latent). MATERIALS AND METHODS: We retrospectively reviewed the medical records of all adults (≥17 years old) hospitalized (between 2003 and 2012) at a tertiary referral center for acute mastoid infections or AOM not responding to outpatient medical treatment. RESULTS: Of the 160 patients in the study sample, 19% had an infection caused by S. pyogenes, 14% by S. pneumoniae, and 11% by P. aeruginosa. AOM was the most common infection (38%), whereas 33% had acute mastoiditis (AM), 18% had latent mastoiditis (LM), and 13% AM of a chronically infected ear (AMc). In contrast to the other infections, P. aeruginosa (30%) and S. aureus (25%) were most common in AMc. Otorrhea (83%), tympanic membrane perforation (57%), and hearing problems (83%) were common in S. pyogenes infections. Patients with S. pneumoniae had longer lengths of hospitalization than those with other bacterial infections (7 vs. 4 days). Otorrhea (94%) and retroauricular symptoms were more common in P. aeruginosa infections. Hearing symptoms were common (67%) but fever (32%) and retroauricular symptoms were uncommon in AOM. Fever (44%) and mastoid tenderness (65%) were common in AM. Patients with LM underwent the most mastoidectomies (54%). Prior medical conditions, retroauricular symptoms, otorrhea (90%), and post-infection problems were common in AMc. CONCLUSION: The bacteriological etiology of hospitalized AOM more closely resembled those of LM and AM than that of AMc. Adults hospitalized for AOM or AM required fewer mastoidectomies than those hospitalized for LM or AMc.
