[Clinical case of tuberculous otitis media in early childhood]. / Klinicheskii sluchai tuberkuleznogo srednego otita v rannem detskom vozraste.

Nowadays, the incidence of tuberculosis remains high all over the world, despite the vaccination, medical support, social policy. The main reasons for this are the high level of migration, the prevalence of bad habits, the prevalence of immunodeficiency conditions, the formation of resistance to antimicrobial drugs, the tendency to refuse vaccination. At the same time, great difficulties arise in the diagnosis of extrapulmonary forms of infection. The purpose of this publication is to remind about the peculiarities of the course and diagnosis of tuberculous otitis media. According to the literature, the main characteristic features of tuberculous of the middle ear are prolonged suppuration without pronounced pain syndrome, inefficiency of standard antibacterial therapy, the anamnestic data about contacts or violation of the vaccination schedule, multiple perforations and a pronounced granulation process during otoscopy, a pronounced destructive process in the temporal bone during X-ray examination. The article presents a clinical case of the development of tuberculous otitis media in a young child with delayed diagnostics and the development of mastoiditis with required emergency surgical treatment. Verification of the etiology of the disease and the specific treatment carried out made it possible to achieve complete relief of ear symptoms, restoration of the tympanic membrane and ventilation of the middle ear.

Risk factors for recurrent acute mastoiditis in pediatric patients: a registry-based cohort study.

OBJECTIVE: To describe characteristics of pediatric patients with recurrent acute mastoiditis, and to identify risk factors for this condition. STUDY DESIGN: A retrospective cohort study. SETTING: Data based on electronic medical records of the largest Health Maintenance Organization in Israel. METHODS: Children hospitalized due to acute mastoiditis during the years 2008-2018 were identified, and their diagnosis was verified. Patients with recurrent acute mastoiditis were identified and grouped, and their characteristics were outlined and compared to those of the original group to identify risk factors for recurrence. RESULTS: During the 11-year period, a total of 1115 cases of children hospitalized due to acute mastoiditis were identified with a weighted incidence rate of 7.8/100,000. Of this group, 57 patients were diagnosed with recurrence following a full clinical recovery. The incidence proportion of recurrent acute mastoiditis was 5.1% (57/1115), male-to-female ratio was 27:30, 73.4% were younger than 24 months, the median period from the first episode was 3.4 months (IQR 2.0;10.0), and 82.5% of the patients (n = 47) had a single recurrence, whereas 18.5% (n = 10) had two recurrences or more. Mastoidectomy and swelling over the mastoid area during the first episode were identified as the main risk factors for recurrent mastoiditis HR = 4.7 [(2.7-8.2), p < 0.001] and HR = 2.55 [(1.4-4.8), p = 0.003], respectively. Mastoidectomy was the only independent significant risk factor for recurrence in a multivariate analysis. CONCLUSIONS: Mastoidectomy and swelling over the mastoid area during the first episode of acute mastoiditis were found strongly related independent risk factor for future recurrent episodes of acute mastoiditis.

High risk and low prevalence diseases: Acute mastoiditis.

INTRODUCTION: Acute mastoiditis is a serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE: This review highlights the pearls and pitfalls of mastoiditis, including the presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION: Acute mastoiditis most commonly affects pediatric patients and is a suppurative infection of the mastoid air cells. It is often associated with otitis media, and common bacteria include Streptococcus and Staphylococcus. History and examination may reveal tympanic membrane erythema, pinna protrusion, postauricular erythema, mastoid tenderness with palpation, external canal swelling, otorrhea, fever, and malaise. The disease should be suspected in those who fail treatment for otitis media and those who demonstrate the aforementioned abnormalities on examination and systemic symptoms. Laboratory analysis may reveal evidence of systemic inflammation, but a normal white blood cell count and other inflammatory markers should not be used to exclude the diagnosis. Computed tomography (CT) of the temporal bones with intravenous contrast is the recommended imaging modality if the clinician is unsure of the diagnosis. CT may also demonstrate complications. Treatment includes antibiotics such as ampicillin-sulbactam or ceftriaxone as well as otolaryngology consultation. Complications may include subperiosteal and intracranial abscess, deep neck abscess, facial nerve palsy, meningitis/encephalitis, venous sinus thrombosis, and seizures. CONCLUSIONS: An understanding of acute mastoiditis can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Acute mastoiditis in cochlear implanted children: A single-centre experience / La mastoiditis aguda en niños con implante coclear: experiencia de un solo centro

Background Acute mastoiditis (AM) is the most common complication of acute otitis media and primarily affects children under the age of two; current data on its prevalence in paediatric patients with cochlear implant (CI) are still scant. Proper management of AM in CI children is crucial in order to avoid the implications (financial and emotional) of an explant. Aim of this paper is to describe the cases of AM occurred among young patients with CI in follow up at our department, also in order to evaluate its prevalence, potential predisposing factors, clinical course and therapeutic strategies. Patients and methods Retrospective study. Medical records of all paediatric patients with CI, who had at least one year of follow-up, were searched aiming to identify those who developed AM, from January 1st 2002 to January 31st 2022. The following data were collected and analysed: demographic features, implant type and side, interval between CI surgery and AM, treatment, laboratory tests, clinical course, vaccination history, associated diseases. Results AM was developed by six (1.3%) of the 439 children with CI (541 implanted ears). In total, 9 episodes (2.05 %) were recorded, as three patients reported two consecutive infections. Average time interval between CI surgery, to the first or only AM diagnosis, was 13.8 months (range 3–30 months). Furthermore, 3/6 of patients had a history of recurrent acute otitis media; 2/6 an autism spectrum disorder, associated to a combined immune deficiency in one case. All patients were hospitalized and promptly treated by intravenous antibiotic therapy; 4/6 also underwent a mastoidectomy. CI was not explanted in any cases of this series. Conclusions Over a 20-year period, AM rate in CI children was 1.3%, which is consistent with the current literature rates of 1–4.7%. All cases were successfully treated, preserving the integrity of the device. ... (AU)

Introducción La mastoiditis aguda (MA) es la complicación más común de la otitis media aguda y afecta principalmente los niños menores de dos años; los datos actuales sobre su prevalencia en pacientes pediátricos con implante coclear (IC) son aún escasos. El manejo adecuado de la MA en los niños con IC es crucial para evitar las implicaciones (económicas y emocionales) de un explante. El objetivo de este articulo es describir los casos de MA ocurridos en pacientes jóvenes con IC en seguimiento en nuestro servicio, también para evaluar su prevalencia, posibles factores predisponentes, curso clínico y estrategias terapéuticas. Pacientes y métodos Estudio retrospectivo. Se realizaron búsquedas en las historias clínicas de todos los pacientes pediátricos con IC, que tenían al menos un año de seguimiento, con el objetivo de identificar a aquellos que desarrollaron la MA, desde el 1 de enero de 2002 hasta el 31 de enero de 2022. Se recopilaron y analizaron los siguientes datos: características demográficas, tipo de implante y lado, intervalo entre cirugia del IC y MA, tratamiento, exámenes de laboratorio, evolución clínica, antecedentes vacunales, enfermedades asociadas. Resultados La MA fue desarrollada por seis (1,3%) de los 439 niños con IC (541 oídos implantados). En total se registraron 9 episodios (2,05 %), ya que tres pacientes reportaron dos infecciones consecutivas. El intervalo de tiempo promedio entre la cirugía del IC y el primer o único diagnóstico de la MA fue de 13,8 meses (rango 3-30 meses). Además, 3/6 de los pacientes tenían antecedentes de otitis media aguda recurrente; 2/6 un trastorno del espectro autista, asociado a una inmunodeficiencia combinada en un caso. Todos los pacientes fueron hospitalizados y tratados de inmediato con terapia antibiótica intravenosa; 4/6 también se sometieron a una mastoidectomía. El IC no fue explantado en ningún caso de esta serie. Conclusiones ... (AU)

A Novel Diagnostic and Treatment Algorithm for Acute Mastoiditis in Children Based on 109 Cases.

BACKGROUND: Acute mastoiditis (AM) is a potentially life-threatening condition primarily affecting children. To date, there are no consistent criteria or valid guidelines for the diagnosis and treatment of pediatric AM. Therefore, this study evaluates the clinical course of AM in terms of clinical signs and treatment. In addition, a novel classification scheme for the disease and a treatment algorithm is being proposed. METHODS: Patient records over a 12-year period from a single center were reviewed to identify confirmed cases of AM in children. Data collected included clinical signs, body temperature, and infection parameters during the disease, as well as radiological imaging, antibiotics, and surgical as well as conservative treatment. In addition, a classification of the AM stages was established in accordance with the findings described and practical experience, consisting of four stages (1, mastoidal irritation; 2, mild AM; 3, advanced AM; 4, advanced AM and additional complications) with corresponding treatment recommendations. In the retrospective cohort, those AM cases that were treated alongside the classification were compared with the rest concerning clinical course and outcome. RESULTS: A total of 109 patients (mean age, 3.8 ± 3.8 years) were included. The main symptoms at hospital admission were auricular protrusion (n = 73; 67.0%), fever (n = 56; 51.4%) with a mean temperature of 38.3 ± 1.1°C, and otalgia (n = 28; 25.7%). The mean laboratory-tested levels of leukocytes and C-reactive protein at the time of hospital admission were 15.96 ± 8.7/nl and 59.6 ± 54.0 mg/L, respectively. During winter, there was a higher prevalence of AM, with peak hospital admissions in April (n = 22). The most common pathogen was Streptococcus pyogenes (32 cases). Treatment was purely conservative in four cases, whereas the remaining cases underwent surgery (41× grommet insertion, 64× plus mastoidectomy). The outcome was generally good, but in eight patients a second surgical procedure had to be performed as they showed signs of clinical deterioration. A total of 101 patients were treated according to the proposed algorithm, and all of which had a good outcome without the need for further interventions. CONCLUSION: Based on clinical experience in a large cohort of pediatric AM patients, a novel diagnostic and treatment algorithm has been developed and successfully tested in a retrospective cohort for AM in children to prevent further complications and to ease its management by pediatricians and otorhinolaryngologists in the emergency setting.

Cuando los vómitos no son causados por un virus / When vomiting is not caused by a virus

La otitis media aguda (OMA) es un diagnóstico muy frecuente en Atención Primaria, a veces se complica con supuración y, en otras ocasiones, menos frecuentemente, con mastoiditis. Se presenta el caso de una niña de 6 años que, tras ser diagnosticada de OMA supurada e instaurarse tratamiento antibiótico, comienza con vómitos, mareos y cefalea, así como con un mal control del dolor con la analgesia habitual y posterior fotofobia. Tras varias visitas, acaba por diagnosticarse una mastoiditis con trombosis del seno transverso, sigmoideo y yugular. La importancia del caso radica en una rápida sospecha de las posibles complicaciones de una otitis media para realizar un diagnóstico y tratamiento precoz de las mismas. (AU)

Acute otitis media (AOM) is a very frequent diagnosis in Primary Care, sometimes complicated with suppuration, and less frequently, with mastoiditis. We present the case of a 6-year-old girl who, after being diagnosed with suppurative AOM and starting antibiotic treatment, began with vomiting, dizziness and headache, as well as poor pain control with the usual analgesia and subsequent photophobia. After several visits, a mastoiditis with thrombosis of the transverse, sigmoid and jugular sinuses was finally diagnosed. The importance of the case lies in a rapid suspicion of possible complications of otitis media in order to diagnose and treat them early. (AU)

X-linked Agammaglobulinemia Diagnosed Following Bezold's Abscess: A Case Report.

Bezold's abscess is an extracranial complication of otitis media, in which a cervical abscess forms from the mastoid process through an ostial fistula, and is a rare condition in recent years. In this study, we experienced a X-linked agammaglobulinemia, which was discovered due to Bezold's abscess. Case: A 12-year-old boy suffering from recurrent right suppurative otitis media for three months was treated with tympanostomy and oral antibacterial therapy at a local otorhinolaryngology clinic. The patient visited the clinic due to a recurrence of symptoms. CT showed bony defects in the cortical bone and mastoid process of the lateral side of the right mastoid cell. The patient was referred to our hospital, admitted the same day and underwent emergency surgery. Intraoperative findings led to the diagnosis of acute mastoiditis and Bezold's abscess c aused b y mastoiditis spreading to the s ternocleidomastoid muscle. After drainage and administration of ABPC/SBT, the abscess disappeared, and the patient's general condition improved. Subsequently, a blood typing test performed on admission suggested the influence of low immunoglobulin levels. A close examination by the pediatric department led to a diagnosis of X-linked agammaglobulinemia. As a result, the patient receives regular immunoglobulin therapy and has been free of infection, including Bezold's abscess. CONCLUSIONS: In the case of recurrent otitis media and rare infections, congenital immune abnormalities should be considered.

IgG4-Related Disease of Temporal Bone Presenting as Unilateral Mastoiditis and Cerebral Thrombosis in a 22-Year-Old Man.

BACKGROUND Immunoglobulin G4-related disease (IgG4-RD) is a rare autoimmune disease that can affect multiple organs and manifest itself as a mass at any region of the body. Due to its several differential diagnoses, investigation and treatment are still challenging. Therefore, imaging, serology, and histopathology are required to confirm the diagnosis. The involvement of the temporal bone is an uncommon presentation, often mistaken for malignancy, with vague symptoms. Therefore, we present a 22-year-old Brazilian man, diagnosed with IgG4-related disease, manifesting with unilateral mastoiditis, sensorineural hearing loss, cerebral venous sinus thrombosis, and a mass in the left temporal bone. CASE REPORT A 22-year-old Brazilian male patient first presented with coughing and precordialgia. Chest scans showed pleural effusion and diffuse areas of ground-glass opacity. A year later, the patient developed severe headache, along with aural fullness, facial pressure, and otorrhea. Imaging detected cerebral thrombosis with failure in the filling of the transverse and left sigmoid sinuses and pachymeningeal thickening in the right cerebral hemisphere, with contrast enhancement. Pure tone audiometry showed thresholds consistent with severe sensorineural hearing loss in the left ear. The patient underwent mastoidectomy with removal of large amounts of inflammatory tissue that were sent to histopathological analysis with compatible signs of IgG4-RD. Corticosteroids and rituximab completed the treatment. CONCLUSIONS Early recognition and appropriate treatment of IgG4-RD are imperative to avoid complications and serious irreversible organ damage. This report has presented an atypical case of IgG4-RD of the left temporal bone that was diagnosed and managed according to current guidelines.

Characteristics of pediatric recurrent acute mastoiditis: A case-control study.

BACKGROUND: Data on pediatric recurrent acute mastoiditis are lacking, despite its morbidity and clinical significance. Our aim was to describe the incidence, characteristics, and associated factors of recurrent mastoiditis in hospitalized children. METHODS: Using a case-control design, analyzing electronic data of hospitalized children with acute mastoiditis between June 2011 and December 2018, children with recurrent mastoiditis were compared to children with a single episode at the time of hospitalization. Recurrent episodes of mastoiditis were compared to the first episodes. Recurrent acute mastoiditis was defined as recurring mastoiditis ≥4-weeks after a completely resolved event. RESULTS: Of 347 children hospitalized with acute mastoiditis, 22 (6.3%) had recurrent mastoiditis; the median interval between episodes was 3 months (range: 1-36). The mean ± SD age was 2.3 ± 2.25 years. A comparison of first episodes in recurring cases to single episodes by univariate and multivariate analysis, showed no differences in the pre-admission management or in the isolated pathogens; however, a history of atopic dermatitis and percutaneous abscess drainage were more frequent in first episodes of recurring cases (27.3% vs. 1.2%, p < 0.001, and 27.3% vs. 10.0%, p = 0.026, respectively). The second episode of acute mastoiditis was characterized by a milder clinical course and shorter durations from symptoms to hospitalization, intravenous antibiotic therapy, and length of hospital stay. Linear regression showed that an increased interval from symptoms to hospitalization significantly increased length of hospital stay (regression coefficient of 0.215 [95% CI: 0.114-0.317], p < 0.001). CONCLUSIONS: Recurrent episodes of mastoiditis were clinically milder, with shorter length of hospital stay compared to first episodes, possibly because of early admission.

Diagnosing acute mastoiditis in a Pediatric Emergency Department: a retrospective review.

Background and aim Acute mastoiditis (AM) is a common complication of acute otitis media in children. There is currently no consensus on criteria for diagnosis. Head CT is the most frequent diagnostic tool used in the ED although the increasing awareness on the use of ionized radiations in children has questioned the use of CT imaging versus solely using clinical criteria. Our research aimed to understand if CT imaging was essential in making a diagnosis of AM. Methods We retrospectively analyzed medical records from pediatric patients who accessed our Pediatric Emergency Department (ED) between January 2014 and December 2020, with a clinical suspicion of AM. We reviewed clinical symptoms upon presentation, head CT and lab values (white blood cell count or WBC, C-Reactive Protein or CRP) when done, presence of complications and discharge diagnosis. A multilogistic regression model was specified to establish the role of clinical features and of CT in the diagnosis of AM based on 77 patients. Results Otalgia (OR= 5.01; 95% CI= 1.52-16.51), protrusion of the auricle (OR= 8.42; 95% CI= 1.37-51.64) and hyperemia (OR= 4.07; 95% CI= 1.09-15.23) of the mastoid were the symptoms strongly associated with a higher probability of AM. In addition to clinical features, the adjusted OR conferred by head CT was 3.09 (95% CI = 0.92-10.34). Conclusions Clinical signs were most likely predictive of AM in our sample when compared to Head CT. Most common symptoms were protrusion of the auricle, hyperemia or swelling behind the ear and otalgia.

Neurosurgical outcomes of pediatric cerebral venous sinus thrombosis following acute mastoiditis: a systematic review and meta-analysis.

OBJECTIVE: Neurosurgical outcomes are not well defined in the management of pediatric patients with cerebral venous sinus thrombosis (CVST) following acute mastoiditis. Specific notable sequelae are otogenic (otitic) hydrocephalus and CVST management. Correspondingly, the aim of this study was to integrate the currently published metadata to summarize these outcomes. METHODS: Electronic searches were performed using the Ovid Embase, PubMed, Scopus, and Cochrane databases from inception to November 2022 following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Cohort-level data were then abstracted for analysis for appropriate pediatric patients. Outcomes were pooled by random-effects meta-analyses of proportions where possible. RESULTS: Twenty-three study cohorts describing 312 pediatric patients with otogenic CVST were included. At a cohort level, the median patient age was 6 years among 181 boys (58%) and 131 girls (42%). Modeling indicated papilledema at presentation in 46% of cases (95% CI 30%-62%). Regarding management, antibiotics were applied universally in all cases, mastoidectomy or other otologic surgery was performed in 91% (95% CI 82%-98%), and prophylactic anticoagulation was administered in 86% (95% CI 75%-95%). There was only 1 case (0.3%) of postprocedural intracranial hemorrhage, and there were no deaths reported among all studies. Although diagnostic lumbar puncture was performed in 14% (95% CI 3%-28%) at presentation, clinical otogenic hydrocephalus was ultimately suspected in 31% (95% CI 14%-49%), and acetazolamide was given in 65% (95% CI 35%-91%) overall. There were 10 cases (3%) that proceeded to permanent CSF diversion in the form of ventricular shunting. At a median follow-up of 8 months among all studies, the venous sinus was completely recanalized in 67% (95% CI 53%-79%). CONCLUSIONS: Most CVSTs following acute mastoiditis will recanalize with the standard use of antibiotics, otologic surgery, and anticoagulation, with minimal symptomatic hemorrhage risk. However, an appreciable proportion of these patients will develop symptomatic otogenic hydrocephalus, and it is imperative that the appropriate surveillance and workup is performed to fully optimize patient outcomes long-term. The possible need for permanent CSF diversion should be recognized.

Otitis externa caused by Malassezia slooffiae complicated with mastoiditis: A case report.

Herein, we report a case of otitis externa caused by Malassezia slooffiae complicated with mastoiditis. A 70-year-old male complained of fever and severe otorrhea from left external auditory canal 2 months after undergoing a craniotomy to remove a hematoma. He had right-sided paralysis and undertook bed rest. Brain computed tomography revealed continuous fluid accumulation in the left mastoid air cells and middle ear from left external auditory canal in addition to leukocytosis and increased C-reactive protein level. The tympanic membrane was severely swelling. These results indicated the presence of otitis media and mastoiditis. Otorrhea culture showed large amounts of M. slooffiae. The administration of liposomal amphotericin B (L-AMB), the irrigation of external auditory canal with normal saline, and the application of topical ketoconazole ointment were started. The administration of L-AMB for 8 weeks and voriconazole, which was switched from L-AMB, for 4 weeks ameliorated his infection and he was transferred to another hospital to receive rehabilitation. From these results and his clinical course, the diagnosis of otitis externa caused by Malassezia slooffiae complicated with mastoiditis was made. And the possibility of the contamination by M. slooffiae was very low. Clinicians should be aware that M.slooffiae can provoke otological infections since M. slooffiae is the most common Malassezia sp. in external auditory canal.

[Outpatient Antibiotic Prescription Rates and Mastoiditis in Children and Adolescents, Saarland, 2014-2019]. / Ambulante Antibiotika-Verordnungsrate und Mastoiditis-Fälle bei Kindern und Jugendlichen im Saarland, 2014­2019.

BACKGROUND: Infections of the respiratory tract are the main indication for outpatient antibiotic therapy in children and adolescents. In recent years the antibiotic prescription rate (APR) in the pediatric population has decreased significantly. OBJECTIVES: The aim of the retrospective mastoiditis audit in the PaedineSaar network is to investigate the incidence of inpatient acute mastoiditis (AM) in Saarland (2014-2019) regarding to the decreasing APRs in children, as well as to gather data of the clinical course of AM. METHODS: All inpatient AM cases 2014-2019 were analyzed retrospectively from 6 hospitals for pediatrics and/or otorhinolaryngology in Saarland and Trier. Children and adolescents aged 0-17 years and residing in Saarland were included in the study. RESULTS: 2014-2019 53 inpatient treated AM cases have been recorded. During the study period there was no significant increase of AM incidence (mean incidence 2014-2019: 6.1/100,000). 34% (18/53) of the patients received prehospital antibiotic treatment (main indication: acute otitis media (AOM) 15/18, 83%). At least one complication occurred in 30% of the patients (16/53). There was a slight trend to more complications in children without oral antibiotic treatment before admission (14/35 (40%) vs. 2/18 (11%) p=0.056). CONCLUSIONS: The incidence of AM leading to inpatient treatment in children in Saarland did not increase 2014-2019 despite a significant and sustained decline in the outpatient APRs. The results of this audit should be used for the development of a more standardized approach concerning the diagnostics and treatment of children with AM.

Management of otogene extracranial complications in children and adolescents: report of 35 cases over 10 years.

OBJECTIVE: Medical management of exocranial otogenic complications represents a challenge for a medical system of a country in general, especially for ENT services. The goal of this study is to find some answers on demographic data, clinical symptoms and signs, diagnostics, and especially therapy for these complications in young patients. METHOD: The study is retrospective, performed in the ENT clinic of the University Clinical Center of Kosova in Prishtina and covers 10 years (from 01.06.2000 to 01.06.2010) and includes all young aged patients (1-18 years) hospitalized because of exocranial otogenic complications. RESULTS: From a total of 35 patients, male were 22 (63%) and females 13 (37%). The commonest complications were: mastoiditis in 18 (51.4%) and subperiosteal mastoidal abscess in 12 cases (34%) than rarest complications were: Bezold's abscess in 2 cases, facial nerve paresis, labyrinthitis, and combined complication one case each. Diagnostics of these cases were based on the clinical appearance, laboratory analyses, and clinical imaging. Treatment of these patients was surgical, medical, and combined: 3 of the medical therapy only (intravenous antibiotics), and 32 others were treated surgically: cortical mastoidectomy in 16 (45%) of cases, mastoidectomy and aeration tube insertion in 6 (17%) and antrotomy in 3 (8.5%) of cases. None of these series of patients died and none of them had permanent sequels. CONCLUSION: Timely diagnostics and adequate treatment of exocranial otogenic complications made it possible that our results can be comparable with the results of other referent centers cited in the recent literature.

Petrous Carotid Artery Thrombosis in an Immunocompromised Patient Presenting With Mastoiditis, A Case Report.

OBJECTIVES: The neurotologic literature commonly describes venous sinus thrombosis as a complication of mastoiditis. However, thrombosis of the internal carotid artery in the setting of mastoiditis is rarely described. We aim to document a case of carotid artery thrombosis in a patient presenting with mastoiditis. METHODS: We describe this case and review relevant literature. RESULTS: A renal transplant patient was transferred to our hospital with a left middle cerebral artery (MCA) infarct due to acute mastoiditis. Examination demonstrated middle ear effusion and radiologic workup confirmed mastoid infection adjacent to the site of arterial thrombosis. During cortical mastoidectomy and facial recess approach to the middle ear, the petrous carotid bone was found to be dehiscent with pneumatization of the petrous apex. Thrombosis was found to resolve following surgery, IV antibiotics and anticoagulation. Clinically, his focal neurological deficits improved. Proximity of the infectious process to an exposed petrous carotid artery supports the hypothesis that this patient's thrombus was a product of infectious spread and extra-luminal compression. CONCLUSION: To our knowledge, this is the first report of MCA infarction due to petrous ICA arterial thrombus in the setting of mastoid infection. The patient's immunocompromised state may have predisposed and contributed to the adverse outcome. We advocate for aggressive management of acute mastoiditis in the immunocompromised to prevent or manage complications (such as venous thrombophlebitis as well as ICA thrombus) as these patients don't show typical signs of infection and inflammation.

A scoping review of the management of acute mastoiditis in children: What is the best approach?

BACKGROUND: Acute mastoiditis (AM) is a severe infection of the mastoid air cells that occurs in cases of acute, sub-acute, or chronic middle ear infections. No definitive consensus regarding the management of AM has been identified. The current guidelines include a conservative approach (parenteral antibiotics alone, antibiotics plus minor surgical procedures such as myringotomy with a ventilation tube inserted or drainage of the subperiosteal abscess through retro-auricolar incision or needle aspiration) or surgical treatment (mastoidectomy). The main aim of this review was to evaluate and summarize the current knowledge about the management of pediatric AM by analyzing the current evidence in the literature. METHODS: We examined the following bibliographic electronic databases: Pubmed and the Cochrane Library, from the inception date until February 2023. The search was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISM). The key words used for the search across electronic databases were: `mastoiditis` and `management`; `mastoiditis` and `surgery`; `mastoiditis` and `conservative`; `mastoiditis` and `antibiotics`; `mastoiditis` and `myringotomy`; `mastoiditis` and `grommet`; `mastoiditis` and `drainage`; and `mastoiditis` and `mastoidectomy`. RESULTS: We selected 12 articles involving 1124 episodes of mastoiditis. Some of these studies considered medical therapy alone as a valid first step, whereas others considered a minor surgical intervention as an initial approach along with antibiotic therapy. Considering the studies that evaluated medical therapy as the initial sole treatment option, the success rate of antibiotics alone was 24.6%. Overall, the success rate of minor surgical procedures, excluding mastoidectomy, was 87.7%, whereas the mastoidectomy success rate was 97%. CONCLUSIONS: Overall, there is no shared consensus on the diagnostic or therapeutic approach to mastoiditis. Conservative therapy has gained considerable ground in recent times, quite limiting the predominant role of mastoidectomy. Further studies will be necessary to definitely develop standardized protocols shared in the scientific community.

[Rare observation of petrositis complicated by parapharyngeal abscess in an 8-year-old patient]. / Redkoe nablyudenie petrozita, oslozhnennogo parafaringeal'nym abstsessom, u patsienta 8 let.

A clinical case of diagnosis and treatment of an 8-year-old patient with bilateral acute suppurative otitis media (ASOM) complicated by left mastoiditis and petrositis is presented. By itself, such a rare complication of ASOM as petrositis manifested itself not in the form of the classic Gradenigo triad, but as a parapharyngeal abscess (PPA), due to the destruction of the lower wall of the temporal bone pyramid. Complications arose as a result of contact and hematogenous pathways for the spread of the infection, which debuted in the middle ear cavities 1 month before the patient was admitted to the hospital. The combination of factors such as an aggressive pathogen, the anatomical structure of the middle ear, a decrease in the immune reactivity of the child's body, the spread of infection through the lower cells of the temporal bone pyramid and the lack of timely antibiotic therapy, led to destructive changes in the bony walls of the temporal bone and the spread of a purulent process to the temporal pyramid bones, and then to the parapharyngeal space. The destruction by inflammation of the lower wall of the pyramid of the temporal bone led to the development of PPA, and not meningoencephalitis, which could have fatal consequences.

Profile of paediatric tuberculosis mastoiditis - a case series.

BACKGROUND: Tuberculosis (TB) otitis media is an uncommon site of extrapulmonary TB and can primarily present as a complicated TB mastoiditis (TBM). This complication is rare in children, even in TB endemic areas but necessitates early identification as delays can lead to severe morbidities. We describe the clinical characteristics as a case series to raise awareness of the condition, and highlight fundamentals related to diagnosis and management. METHODS: A retrospective chart review of clinical and radiological information of five children with TBM seen at the Red Cross War Memorial Children's Hospital in Cape Town, South Africa, over the last 5 years. Variables collected included symptomatology, duration of disease, investigations and management. RESULTS: All were under 5 years of age and presented with typical features of acute bacterial mastoiditis. Mean duration of symptoms was 12 days (range 3-30 days). Two children had known TB contacts. Two children had pulmonary involvement, one with miliary TB. CT of the temporal bone demonstrated extensive bony destruction of the petromastoid and demineralised ossicles in all cases. Three children had intracranial extension. Four children demonstrated hearing loss between 30 dB and 83 dB. Necrotising granulomatous inflammation was present in the mastoid specimens in all cases. Confirmatory diagnosis was made via GeneXpert polymerase chain reaction (PCR) (2), Ziehl-Nielson (ZN) stain (1) or a positive TB culture (2). Postoperatively, one patient had normal hearing, two patients had mild conductive hearing loss (CHL), one had mild-moderate CHL and one had profound hearing loss. CONCLUSION: Delays in identification and management result in marked bony destruction and hearing loss. Radiological and surgical findings typical of TBM, therefore, require tissue sampling from the ear for urgent microscopic, PCR and histologic testing, allowing the avoidance of a mastoidectom. In a TB endemic setting, children with typical findings and necrotising granulomatous inflammation on histology should be considered for prompt commencement of anti-TB therapy while awaiting a definitive diagnosis.
