Abstract
An encephalocele is a cranial defect that allows brain matter to present in other portions of the skull. We present a case of a 57-year-old female who presented to the ICU with fever and unresponsiveness and was diagnosed with meningitis, bacteremia, and pneumonia. After diagnostic imaging was performed, a nasofrontal encephalocele was found and corrected via surgical intervention. The patient's nasofrontal encephalocele caused a predisposition for opportunistic infections due to the exposed and unprotected brain matter, which caused a simple case of sinusitis to turn into a life-threatening case of meningitis and bacteremia.

Abstract
Meningoencephalitis refers to inflammation of the brain and meninges. It can be caused by various organisms, such as Neisseria meningitidis, Streptococcus pneumoniae, and so on. Staphylococcus aureus causing meningoencephalitis is relatively rare. It is mainly encountered in patients who have undergone surgeries in the past. Acute leukoencephalopathy with restricted diffusion (ALERD) is a type of encephalopathy that can involve both white and grey matter of the brain, and it has a characteristic "bright tree appearance" on MRI. It can be because of various infectious etiologies or caused by various toxins. Neurological sequelae are observed in about two out of three cases. Here, we describe a case of S. aureus meningoencephalitis with ALERD, which has been seldom reported. More awareness about this is required among primary care physicians for timely diagnosis and management to prevent any complications.

Abstract
ABSTRACT Background. Identifying the causative pathogens of central nervous system infections (CNSIs) is crucial, but the low detection rate of traditional culture methods in cerebrospinal fluid (CSF) has made the pathogenic diagnosis of CNSIs a longstanding challenge. Patients with CNSIs after neurosurgery often overlap with inflammatory and bleeding. Metagenomic next-generation sequencing (mNGS) has shown some benefits in pathogen detection. This study aimed to investigate the diagnostic performance of mNGS in the etiological diagnosis of CNSIs in patients after neurosurgery. Methods. In this prospective observational study, we enrolled patients with suspected CNSIs after neurosurgical operations who were admitted to the intensive care unit of Beijing Tiantan Hospital. All enrolled patients' CSF was tested using mNGS and pathogen culture. According to comprehensive clinical diagnosis, the enrolled patients were divided into CNSIs group and non-CNSIs group to compare the diagnostic efficiency of mNGS and pathogen culture. Results. From December 2021 to March 2023, 139 patients were enrolled while 66 in CNSIs group and 73 in non-CNSIs. The mNGS exceeded culture in the variety and quantity of pathogens detected. The mNGS outperformed traditional pathogen culture in terms of positive percent agreement (63.63%), accuracy (82.01%), and negative predictive value (75.00%), with statistically significant differences ( P < 0.05) for traditional pathogen culture. The mNGS also detected bacterial spectrum and antimicrobial resistance genes. Conclusions. Metagenomics has the potential to assist in the diagnosis of patients with CNSIs who have a negative culture.

J Family Med Prim Care 2023; 12:1893-1900.

Abstract
Background Meningitis can be attributed to bacterial, fungal, or viral agents. In this study, we demonstrate the common bacterial agents causing meningitis along with their antibiotics susceptibility pattern in patients of all age groups. Material and Methods This retrospective, observational study was carried out in the Department of Microbiology with cerebrospinal fluid (CSF) samples collected from November 2019 to May 2022. We collected 1986 nonrepeat CSF samples from clinically suspected patients of bacterial meningitis, and clinical information about the patients was extracted from the hospital information system. Results Out of the 1986 CSF samples included in our study, 150 (7.55%) were found to be positive on bacterial culture. Most of our patients were in the age group of 0-20 years. Common clinical manifestations observed in our patients were: high-grade fever, 87 patients (58%); severe headache, 126 patients (84%); neck rigidity, 47 patients (31.3%); altered mental status, 76 patients (50.7%) and photophobia, 83 patients (55.3%). The most commonly isolated bacteria was Acinetobacter species (30%). The mean length of hospitalization (37.76 ± 25.30), the mean total cell count, high levels of protein (mg/dl) and low levels of glucose (mg/dl) of CSF were statistically significant in meningitis caused by multidrug-resistant bacteria. Conclusion We recognized the spectrum of pathogens causing meningitis at our center along with the antibiotic resistance pattern to guide and facilitate early treatment by primary health care professionals and family medicine practitioners.

Polymicrobial Bacterial Meningitis in a Patient with Chronic Suppurative Otitis Media: Case Report and Literature Review. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1428.

Abstract
Polymicrobial meningitis is a rare entity in the adult population, especially in the antibiotic era. However, disorders such as chronic suppurative otitis media (CSOM) or even poor oral hygiene are considered risk factors for the development of such cerebral infection. We report a case of polymicrobial meningitis associated with oto-mastoiditis in a 64-year-old female patient known to have CSOM. The patient presented atypical symptoms for community-acquired meningitis, showing subacute evolution of headache, without fever or neck stiffness. The aerobe microorganisms Streptococcus anginosus and Corynebacterium spp., sensitive to beta-lactamines, and the anaerobe Prevotella spp., resistant to penicillin and metronidazole, were isolated from CSF specimens, while Proteus mirabilis and Enterococcus faecalis were identified from the ear drainage. The diversity of pathogens identified in our case led us to the hypothesis of two different sources of meningitis: otogenic and/or odontogenic. Favorable evolution was obtained after a multi-disciplinary approach, combining surgery and broad-spectrum antibiotics. In addition, we performed a literature review that highlights the low incidence of polymicrobial mixed aerobe-anaerobe meningitis.

Abstract
Bacterial meningitis is a cause of global concern given its associated high rates of mortality and complications. Timely diagnosis and management are crucial in improving outcomes in patients. Lumbar puncture and radiological investigations form the crux of diagnosis. However, the clinical course becomes complicated if lumbar puncture results are unrevealing and equivocal for bacterial meningitis. We present a case of a 60-year-old female who was diagnosed with bacterial meningitis on repeated lumbar puncture. Clinical vigilance and a high degree of suspicion is needed to ensure that patients with bacterial meningitis are diagnosed and managed appropriately, especially in cases with inconclusive lumbar puncture or radiological investigations.
