Abstract
OBJECTIVE A bacterial brain abscess may damage surrounding brain tissue by mass effect, inflammatory processes, and bacterial toxins. The aim of this study was to examine cognitive and functional outcomes at 8 weeks and 1 year following acute treatment. METHODS Prospective study of 20 patients with bacterial brain abscess (aged 17-73 years; 45% females) with neuropsychological assessment at 8 weeks and 1 year post-treatment. Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) and Patient Competence Rating Scale (PCRS) were used to assess everyday functioning and administered to patients and informants. RESULTS Cognitive impairment was found in 30% of patients at 8 weeks and 22% at 1 year. Significant improvements were seen on tests of perceptual reasoning, attention, verbal fluency, and motor abilities (p < 0.05). At 1 year, 45% had returned to full-time employment. Nevertheless, patients and their informants obtained scores within the normal range on measures of everyday functioning (PCRS and BRIEF-A) at 8 weeks and 1 year. No significant improvements on these measures emerged over time. CONCLUSION Residual long-term cognitive impairment and diminished work ability affected 22% and 45% of patients one year after BA. Persistent cognitive impairment emphasizes the importance of prompt acute treatment and cognitive rehabilitation.

Adawe DH, Mengistie DT. Determine the factors affecting the time to recovery of children with bacterial meningitis at Jigjiga university referral hospital in the Somali Regional State of Ethiopia: using the parametric shared frailty and AFT models. BMC Res Notes 2024; 17:85. [PMID: 38504305 PMCID: PMC10953244 DOI: 10.1186/s13104-024-06740-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Accepted: 03/08/2024] [Indexed: 03/21/2024] Open
Abstract
BACKGROUND Neisseria meningitides, Streptococcus pneumonia, and hemophilic influenza type B are frequently linked to bacterial meningitis (BM) in children. It's an infectious sickness that kills and severely mobilizes children. For a variety of reasons, bacterial meningitis remains a global public health concern; most cases and deaths are found in Sub-Saharan Africa, particularly in Ethiopia. Even though vaccination has made BM more preventable, children worldwide are still severely harmed by this serious illness. Age, sex, and co-morbidity are among the risk variables for BM that have been found. Therefore, the main objective of this study was to identify the variables influencing the time to recovery for children with bacterial meningitis at Jigjiga University referral hospital in the Somali regional state of Ethiopia. METHOD A retrospective cohort of 535 children with bacterial meningitis who received antibiotic treatment was the subject of this study. Parametric Shared Frailty ty and the AFT model were employed with log likelihood, BIC, and AIC methods of model selection. The frailty models all employed the patients' kebele as a clustering factor. RESULTS The number of cases of BM declined in young children during the duration of the 2 year, 11 month study period, but not in the elderly. Streptococcus pneumonia (50%), hemophilic influenza (30.5%), and Neisseria meningitides (15%) were the most frequent causes of BM. The time to recovery of patients from bacteria was significantly influenced by the covariates male patients (ϕ = 0.927; 95% CI (0.866, 0.984); p-value = 0.014), patients without a vaccination history (ϕ = 0.898; 95% CI (0.834, 0.965); P value = 0.0037), and patients who were not breastfeeding (ϕ = 0.616; 95% CI (0.404, 0.039); P-value = 0.024). The recovery times for male, non-breastfed children with bacterial patients are 7.9 and 48.4% shorter, respectively. In contrast to children with comorbidity, the recovery time for children without comorbidity increased by 8.7%. CONCLUSION Age group, sex, vaccination status, co-morbidity, breastfeeding, and medication regimen were the main determinant factors for the time to recovery of patients with bacterial meningitis. Patients with co-morbidities require the doctor at Jigjiga University Referral Hospital to pay close attention to them.

Abstract
SCOPE These European Society of Clinical Microbiology and Infectious Diseases guidelines are intended for clinicians involved in diagnosis and treatment of brain abscess in children and adults. METHODS Key questions were developed, and a systematic review was carried out of all studies published since 1 January 1996, using the search terms 'brain abscess' OR 'cerebral abscess' as Mesh terms or text in electronic databases of PubMed, Embase, and the Cochrane registry. The search was updated on 29 September 2022. Exclusion criteria were a sample size <10 patients or publication in non-English language. Extracted data was summarized as narrative reviews and tables. Meta-analysis was carried out using a random effects model and heterogeneity was examined by I2 tests as well as funnel and Galbraith plots. Risk of bias was assessed using Risk Of Bias in Non-randomised Studies - of Interventions (ROBINS-I) (observational studies) and Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) (diagnostic studies). The Grading of Recommendations Assessment, Development and Evaluation approach was applied to classify strength of recommendations (strong or conditional) and quality of evidence (high, moderate, low, or very low). QUESTIONS ADDRESSED BY THE GUIDELINES AND RECOMMENDATIONS Magnetic resonance imaging is recommended for diagnosis of brain abscess (strong and high). Antimicrobials may be withheld until aspiration or excision of brain abscess in patients without severe disease if neurosurgery can be carried out within reasonable time, preferably within 24 hours (conditional and low). Molecular-based diagnostics are recommended, if available, in patients with negative cultures (conditional and moderate). Aspiration or excision of brain abscess is recommended whenever feasible, except for cases with toxoplasmosis (strong and low). Recommended empirical antimicrobial treatment for community-acquired brain abscess in immuno-competent individuals is a 3rd-generation cephalosporin and metronidazole (strong and moderate) with the addition of trimethoprim-sulfamethoxazole and voriconazole in patients with severe immuno-compromise (conditional and low). Recommended empirical treatment of post-neurosurgical brain abscess is a carbapenem combined with vancomycin or linezolid (conditional and low). The recommended duration of antimicrobial treatment is 6-8 weeks (conditional and low). No recommendation is offered for early transition to oral antimicrobials because of a lack of data, and oral consolidation treatment after ≥6 weeks of intravenous antimicrobials is not routinely recommended (conditional and very low). Adjunctive glucocorticoid treatment is recommended for treatment of severe symptoms because of perifocal oedema or impending herniation (strong and low). Primary prophylaxis with antiepileptics is not recommended (conditional and very low). Research needs are addressed.

Abstract
BACKGROUND Central Nervous System (CNS) suppurative infections are serious but rare conditions in the paediatric population. Data on long-term neurocognitive and quality of life outcomes in children recovering from these infections are lacking. METHODS A retrospective cohort review of children <16 years with non-sinogenic infections undergoing neurosurgery was conducted. Data for patients admitted to Children's Health Ireland at Temple St between 2008-2021 were analysed for clinical and microbiological profiles. Follow-up reviews evaluating neurological and academic sequelae and quality of life were performed. Categorical variables were analysed for unfavourable outcome with a p < 0.05 significance value. RESULTS Forty patients were included with a mean age of 4.5 years and equal gender distribution. Fever (68%) and vomiting (58%) were the most common presenting complaints. Only fourteen (35%) patients presented with the classic triad of fever, headache, and focal neurological deficit. Meningitis/Encephalitis was the most common cause of suppurative infection (40%). Predisposing factors included congenital heart disease (18%), prematurity (15%) and immunocompromised status (10%). More patients received an initial Burr hole aspiration (73%) than Craniotomy (27%). The re-operation rate was higher in the craniotomy group (45%) compared to the burr hole group (34%), but this was not statistically significant (p = 0.522). Four patients died (10%) including two intra-hospital deaths (5%). Male gender (p = 0.047) and multiple abscesses (p = 0.041) were associated with unfavourable outcome at discharge. Mobility impairment was the most affected determinant of quality of life. CONCLUSION CNS suppurative infections are associated with long-term neurocognitive sequelae in children. Multiple abscesses and male gender are associated with unfavourable GOS on discharge. Children are still left with mobility impairment (25%), personality changes (23%) and intellectual disability (18%) at an average of 5 years. Long-term follow up with multidisciplinary input is required. Further research should focus on evaluating long-term HRQoL in children.

Abstract
Brain abscesses are localized infections in the brain's parenchyma, characterized by inflammation, pus formation, and the development of a surrounding capsule. These lesions typically occur due to underlying factors such as immunosuppression, ear and sinus infections, and contamination during neurosurgery. While brain abscesses are a life-threatening complication of cyanotic heart defects, they are rarely reported, with only sporadic cases previously documented. This article presents the case of an eight-year-old male patient with an uncorrected transposition of the great arteries, who was evaluated for symptoms including headache, fever, and neurological focalization. Diagnostic imaging revealed three lesions consistent with brain abscesses. Furthermore, the causal agents were identified as Streptococcus intermedius and Fusobacterium spp., representing oral microorganisms. Additionally, the patient exhibited poor oral hygiene and dental caries in multiple teeth. This article discusses and integrates the possible pathophysiological mechanisms that allowed a localized dental infection to spread hematogenously and cause brain abscesses in this patient. Prompt management of the infectious source is crucial to prevent a poor prognosis associated with brain abscesses. Therefore, this case emphasizes the importance of regular dental assessments and thromboprophylaxis for patients with underlying cardiomyopathies that cause right-to-left shunting to prevent potential complications.

Abstract
Background Brainstem located abscesses are rare in the pediatric population. Diagnosis of brain abscess can be challenging as patients may present with nonspecific symptoms and the classical triad of headache, fever, and focal neurological deficit is not always present. Treatment can be conservative or a combination of surgical intervention with antimicrobial therapy. Case Description We present the first case of a 4.5-year-old girl with acute lymphoblastic leukemia that developed infective endocarditis (IE) and subsequently developed 3 suppurative collections (frontal, temporal, and brainstem). The patient had negative cerebrospinal, blood, and pus culture growth and subsequently underwent burr-hole drainage of the frontal and temporal abscesses with a 6-week course of intravenous antibiotic therapy with an uneventful postoperative course. At 1 year, the patient is left with minor right lower limb hemiplegia and no cognitive sequelae. Conclusion The decision to surgically intervene for brainstem abscesses is dependent on surgeon and patient factors including the presence of multiple collections, midline shift, the aim of source identification in sterile cultures, and the patient's neurological condition. Patients with hematological malignancies should be monitored closely for IE which is a risk factor for hematogenous spread of brainstem located abscesses.

Abstract
OBJECTIVES To report on population-based epidemiological trends in central nervous system (CNS) abscesses and empyemas in England over five decades. METHODS Trend analyses of age-sex-specific hospital admission and death rates using routinely collected English national hospital discharge records, mortality records, and annual population denominators from 1968 to 2019. RESULTS Hospital admission rates for CNS abscesses and empyemas were stable in England until the late 1980s. In the last two decades of the study period (1999-2019), first-time admissions increased from 1.24 per 100,000 population in 1999 (95% confidence interval [CI] 1.14-1.35) to 2.86 in 2019 (95% CI 2.72-3.01). Admission rates were highest among infants and older adults, and were higher for males than females. There were small but significant increases in annual mortality rates for CNS abscesses and empyemas over the last two decades of the study period after accounting for population ageing, but mortality remained low at around 0.1-0.2 per 100,000 population. Mortality increased with advancing age; deaths in childhood were extremely rare. Case fatality rates where a relevant diagnosis was recorded as either the underlying or contributing cause were 4.3% and 9.7% respectively. CONCLUSIONS The increase in CNS abscesses and empyemas in England might reflect improved case ascertainment, but the likelihood of a true rise in incidence should be considered.

Abstract
BACKGROUND: In children, a cerebral abscess is a rare yet life-threatening condition. Children account for about 25% of all cerebral abscess cases in the general population. One of the most common predisposing factors for developing a cerebral abscess with increased mortality risk is congenital heart disease (CHD).
AIM: This study aims to determine the prevalence of death and factors associated with death in children with CHD and cerebral abscesses.
METHODS: This study is a cross-sectional design which collects retrospective data. Secondary data of CHD patients with cerebral abscesses were retrieved from patients’ medical records.
RESULTS: From January 1, 2012, to December 31, 2021, a total of 107 children with a history of CHD were diagnosed with cerebral abscesses during this study. Thus, mortality rates in cases with cerebral abscess were 38.3% in children with a history of CHD. Patients with a focal infection in the ear, nose, and throat (ENT) area have a 3.6 times higher risk of dying than those with a focal infection elsewhere (odds ratio [OR] = 3.6 [95% confidence interval [CI], 1.57–8.32, p = 0.004). Patients who did not have neurosurgery had a 2.5- fold increased risk of death than those who did (OR = 2.5, 95% CI, 1.11–5.96, p < 0.05). Nutritional status, anemia status, and culture results, which were anticipated to be linked with death in CHD children with cerebral abscess, were not statistically significant.
CONCLUSION: We conclude that this study provides an overview of the prevalence of mortality and variables related to death in incidents of cerebral abscess in children with CHD in Indonesia.

Abstract
Background: Intracranial abscesses have been a diagnostic and therapeutic challenge since
time immemorial for both the microbiologists and the neurosurgeons. There is
paucity of detailed studies documenting the infecting organism causing brain
abscesses in South India. Aims: The study aimed at identifying and assessing the prevalence of aerobic,
anaerobic bacteria and fungi associated with brain abscesses at a tertiary
care hospital in South India. Methods and Material: Eight years data was collected from the records of culture reports from 2007
to 2010 and 2013 to 2018. The corresponding clinical case records were
retrieved for the assessment of risk factors. Risk factors of brain abscess
development were assessed based on clinical cases records. Results: Data from 140 brain abscess cases obtained over a period of 8 years were
analyzed. Out of the 140 samples, 66 (47.14%) were culture positive in which
33 (50%) had single aerobic/facultative anaerobic bacteria, 20 (30.3%) had
mixture of more than one aerobic/facultative anaerobic bacteria, 12 (18.18%)
had single obligate anaerobic bacteria and 1(1.5%) sample had
Mycobacterium tuberculosis isolated. Among the total 92
isolates, Pseudomonas aeruginosa (21/92, 23%) and
Staphylococcus aureus (20/92, 22%) predominated.
Bacteroides fragilis group was the most common obligate
anaerobe isolated. There were no fungal isolates. As there were various
isolates isolated, hence there is heterogeneity of isolates detected
Neuroanatomically, parietal lobe (45/140, 32%) was the most common location.
Otogenic infection was the major risk factor for parietal and temporal lobe
abscess (P value < .05). Conclusions: It has become essential for the microbiologists to be aware of unusual
isolates from brain abscess and its complex nature. Obscurity and difficulty
in their microbiological diagnosis calls for more such detailed studies.

Abstract
PURPOSE OF REVIEW We conducted a systematic review of the literature to update findings on the epidemiology and the management of cerebral abscesses in immunocompetent patients. RECENT FINDINGS Observational studies suggest that the overall prognosis has improved over the last decades but mortality rates remain high. Several parameters may contribute to a better prognosis, including the identification of common risk factors for brain abscess, the systematic use of brain MRI at diagnosis, the implementation of appropriate neurosurgical and microbiological techniques for diagnosis, the optimization of the antibacterial treatment based on epidemiology and pharmacokinetic/pharmacodynamic studies, and a long-term follow-up for detection of secondary complications. Outcome research on brain abscess is mainly based on observational studies. Randomized controlled trials have yet to be performed to identify clinically relevant interventions associated with improved patient-centered outcomes. SUMMARY Our review highlights the importance of a multidisciplinary approach to optimize brain abscess management both at the acute phase and in the long-term. Randomized controlled studies are urgently needed to identify interventions associated with improved outcomes.

Abstract
PURPOSE OF REVIEW Brain nocardiosis is a rare but severe infection mostly occurring among immunocompromised patients. In this review, we present recent data on this infection and address some of the common clinical dilemmas encountered in patients with brain nocardiosis. RECENT FINDINGS Strategies used to approach a patient with suspected brain nocardiosis include the 'conservative strategy' (without early neurosurgery) and the 'neurosurgical strategy' (with early aspiration or excision of brain abscess[es]). The advantages and disadvantages of both strategies are summarised. Our opinion is that the use of the 'conservative strategy' should be limited to well-selected patients presenting with an easily accessible extra-neurological lesion(s) and have brain abscesses at low risk of treatment failure. In terms of antimicrobial therapy, we summarise the data supporting the use of a multidrug regimen in patients with brain nocardiosis.Last, we list possible reasons for treatment failure in patients with brain nocardiosis and suggest interventions to overcome them. SUMMARY Literature is scarce regarding brain nocardiosis, as a consequence of the rarity of this disease. A multidisciplinary and individualised management is required to optimise the outcome of patients with brain nocardiosis.
