Objective:To explore the clinical characteristics and treatment methods of middle ear cholesteatoma with intracranial and extracranial complications as the first diagnosis. Methods:A total of 244 patients were initially diagnosed with intracranial and/or extracranial complications associated with middle ear cholesteatoma at the First Affiliated Hospital of Zhengzhou University from January 2015 to January 2022, and medical records were collected and retrospectively analyzed. Results:Among 244 patients with intracranial and extracranial complications of middle ear cholesteatoma, 203 cases had one complication, 34 cases had 2 complications, and 7 cases had 3 or more complications. One hundred and eighty-six cases presented labyrinthitis, 41 cases had peripheral facial paralysis, 27 cases had periauricular abscess, 12 cases had meningitis, 10 cases had brain abscess, 7 cases had sigmoid sinus lesions, 6 cases had epidural abscess, and 4 cases demonstrated hydrocephalus. Conclusion:The destructive nature of middle ear cholesteatoma can lead to intracranial and extracranial complications. The incidence rate of extracranial complications is highest for labyrinthitis. Patients with otitis media who complained dizziness should raise clinical suspicion for potential labyrinthitis. The second most prevalent extracranial complication is peripheral facial paralysis, and early facial nerve decompression surgery is critical for better recovery of facial paralysis symptoms. Brain abscess is the most common intracranial complications, which has the highest fatality rate. Clinicians should be alert to otogenic brain abscess. Otolaryngology and neurosurgery teams should cooperate and evaluate patients' middle ear lesions and brain abscess, and jointly develop personalized treatment plans.

Objective:To analyze the etiology, diagnosis, treatment of cholesteatoma of temporal bone complicated with brain abscess. Methods:A total of 27 patients with cholesteatoma complicated with brain abscess admitted to the Peoples Hospital of Xinjiang Uygur Autonomous Region from January 2008 to January 2024 were collected, and their clinical characteristics and treatment methods were summarized. Results:Tow patients underwent modify radical mastoidectomy and eliminate abscess by pricking. The other patients underwent ear surgery after neurosurgical treatment of brain abscess. Among them, 19 cases underwent open craniotomy for brain abscess and 5 cases with small abscess were transferred to otorhinolaryngology for radical mastoidectomy after transcranial drainage. Only one patient died, the other patients had a good prognosis without recurrence. Conclusion:OBA is the most serious complication of temporal cholesteatoma with a high mortality rate, and MRI can assist in early diagnosis. Early treatment and multidisciplinary collaboration can improve the cure rate of the disease.

Objective:To analyze the clinical diagnosis, treatment ，and surgical timing of otogenic intracranial complications. Methods:The clinical data of 11 patients with intracranial complications with ear symptoms as the first manifestation in Department of Otorhinolaryngology Head and Neck Surgery, Qilu Hospital of Shandong University（Qingdao） from December 2014 to June 2022 were collected, including 8 males and 3 females, aged from 4 to 69 years. All patients had complete otoendoscopy, audiology, imaging and etiology examination, and the diagnosis and treatment plan was jointly developed through multidisciplinary consultation according to the critical degree of clinical symptoms and imaging changes. Among the 11 patients, 5 cases were treated with intracranial lesions first in neurosurgery department and middle ear lesions later in otolaryngology, 3 cases of meningitis, were treated with middle ear surgery after intracranial infection control, 1 case was treated with middle ear lesions and intracranial infection simultaneously, and 2 cases were treated with sigmoid sinus and transverse sinus thrombosis conservatively. They were followed up for 1-6 years. Descriptive statistical methods were used for analysis. Results:All the 11 patients had ear varying symptoms, including ear pain, pus discharge and hearing loss, etc, and then fever appeared, headache, disturbance of consciousness, facial paralysis and other intracranial complication. Otoendoscopy showed perforation of the relaxation of the tympanic membrane in 5 cases, major perforation of the tension in 3 cases, neoplasia in the ear canal in 1 case, bulging of the tympanic membrane in 1 case, and turbidity of the tympanic membrane in 1 case. There were 4 cases of conductive hearing loss, 4 cases of mixed hearing loss and 3 cases of total deafness. Imaging examination showed cholesteatoma of the middle ear complicated with temporal lobe brain abscess in 4 cases, cerebellar abscess in 2 cases, cholesteatoma of the middle ear complicated with intracranial infection in 3 cases, and sigmoid sinus thrombophlebitis in 2 cases. In the etiological examination, 2 cases of Streptococcus pneumoniae were cultured in the pus of brain abscess and cerebrospinal fluid, and 1 case was cultured in streptococcus vestibularis, Bacteroides uniformis and Proteus mirabilis respectively. During the follow-up, 1 patient died of cardiovascular disease 3 years after discharge, and the remaining 10 patients survived. There was no recurrence of intracranial and middle ear lesions. Sigmoid sinus and transverse sinus thrombosis were significantly improved. Conclusion:Brain abscess, intracranial infection and thrombophlebitis are the most common otogenic intracranial complications, and cholesteatoma of middle ear is the most common primary disease. Timely diagnosis, multidisciplinary collaboration, accurate grasp of the timing in the treatment of primary focal and complications have improved the cure rate of the disease.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Anaerobic infections have been reported to be responsible for 3–10% of pyogenic liver abscesses in Korea, and reported anaerobes include Fusobacterium, Bacillus fragilis, and Bacteroides melaninogenicus. Parvimonas micra is an anaerobic, Gram-positive, non-spore-forming bacterial species and a constituent of normal flora on skin, vagina, gastrointestinal tract, and oral cavity that can cause opportunistic infections. However, it has only rarely been reported to be a cause of liver abscess; only one such case has been reported in Korea. We experienced a case of concomitant liver and brain abscesses caused by Parvimonas micra in a non-immunodeficient 65-year-old female patient without diabetes or periodontal disease. Parvimonas micra infection was confirmed by blood culture using VITEK® 2 cards and by bacterial 16s ribosomal RNA gene sequencing. We conclude that we should not overlook anaerobes as a cause of liver abscess.

Ventriculoperitoneal (VP) shunt insertion is the standard treatment for hydrocephalus; shunt-associated infection is the most common complication after surgery. However, fungal infections are unusual. We present a case of cryptococcal meningitis complicated by a brain abscess and an infected intra-abdominal pseudocyst that developed 14 weeks after VP shunt insertion to treat hydrocephalus in a 74-year-old patient. Cryptococcal central nervous system (CNS) infection has a high mortality rate; however, diagnosis is challenging. Therefore, prompt diagnosis and treatment are required when a cryptococcal CNS infection is suspected in patients with VP shunts.

Eikenella corrodens rarely causes invasive head and neck infections in immunocompetent children. We report a case of epidural abscess caused by E. corrodens in a previously healthy 13-year-old boy who presented with fever, headache, and vomiting. On physical examination upon admission, there was no neck stiffness, but discharge from the right ear was observed. Brain magnetic resonance imaging (MRI) revealed approximately 4.5-cm-sized epidural empyema on the right temporal lobe as well as bilateral ethmoid and sphenoid sinusitis, right mastoiditis, and right otitis media. During treatment with vancomycin and cefotaxime, purulent ear discharge aggravated, and on follow-up brain MRI, the empyema size increased to 5.6×3.4 cm with interval development of an abscess at the right sphenoid sinus. Burr hole trephination was performed, and foul-smelling pus was aspirated from the epidural abscess near the right temporal lobe. Pus culture yielded E. corrodens. Endoscopic sphenoidotomy was also performed with massive pus drainage, and the same organism was grown. The patient was treated with intravenous cefotaxime for 3 weeks and recovered well with no other complications. Therefore, E. corrodens can cause serious complications in children with untreated sinusitis.

The incidence of vaccine-type Streptococcus pneumoniae carriage and disease have declined in vaccinated children as well as in unvaccinated children and adults. However, diseases caused by non-vaccine type (NVT) S. pneumoniae are increasing. In this study, we report an invasive pneumococcal disease (IPD) caused by NVT multidrug-resistant (MDR) S. pneumoniae transmitted from a vaccinated infant to an unvaccinated healthy woman, and the clinical characteristics of this serotype. A 29-year-old previously healthy woman visited our hospital with fever and headache. She had been breastfeeding her baby for 8 months. She was diagnosed with brain abscess and sinusitis caused by S. pneumoniae. Although the patient had no previous exposure to antibiotics, antibiotic susceptibility test identified the pathogen as MDR. The patient's family members were examined using nasopharyngeal swabs for bacterial culture. The serotype of S. pneumoniae identified from the blood, abscess, and sputum of the patient was 15B/C. After investing the patient's family members, we found that the serotype from nasopharyngeal specimen of her baby was the same. We described an invasive MDR pneumococcal disease in an immunocompetent young adult in the community. IPD likely spread to the patient by close contact with her baby, who harbored S. pneumoniae of NVT. The spread of NVT S. pneumoniae in the post-vaccine era has increased in the community, and resistance pattern for S. pneumoniae of 15B/C changed compared to the pre-pneumococcal conjugate vaccine era. The spread of MDR pathogens causing IPD among family members should be monitored.
