RESUMO
BACKGROUND: Central nervous system opportunistic infections can be the first presentation of an HIV infection. Our aim is to describe clinical and laboratory characteristics of HIV-associated Cryptococcal Meningitis (CM), in-hospital outcomes and analyze associations of these parameters with adverse outcomes. METHODS: Observational study of local cohort of HIV-associated cryptococcal meningitis in a high complexity tertiary urban hospital in Santiago, Chile. Descriptive analysis through chart review of all episodes of HIV-associated CM in adults, from 1995 to 2019. Inclusion criteria were confirmed CM with cerebrospinal fluid culture or India ink in the appropriate clinical context and HIV diagnosis. We selected relevant variables that have been described as predictors of adverse outcomes in the literature and explore associations in our cohort. RESULTS: There were 37 HIV associated CM cases, occurring from 2000 to 2019. Majority were men (86â¯%) with a median age of 35 years. CM was the first HIV manifestation in 32â¯%. Opening pressure was measured in 10â¯% of patients at admission. Most CSF parameters were mildly altered, and two patients presented with completely normal CSF findings. Most patients -94,4â¯%- suffered adverse events secondary to antifungal therapy. Despite of recommendations against their use, steroids were frequently prescribed. Mortality was 18,9â¯%, and was associated with older age, and more days of headache prior to admission. CONCLUSIONS: CM clinical presentation and CSF characteristics are variable at presentation, which can lead to delayed diagnosis. Inappropriate use of corticosteroids, antifungal toxicity and suboptimal management of elevated intracranial pressure are key aspects to improve.

Purpose of Review: Despite the availability of effective vaccines against the three primary pathogens (Streptococcus pneumoniae, Haemophilus influenzae type b, and Neisseria meningitidis) that cause bacterial meningitis, this condition remains a significant cause of morbidity, neurologic sequelae, and mortality among children and adults living in low-income and middle-income countries. Recent Findings: Bacterial meningitis represents a significant public health challenge for national and global health systems. Since vaccine-preventable meningitis remains highly prevalent in low-income and middle-income countries, the World Health Organization (WHO) recently developed a global roadmap to defeating meningitis by 2030 and ameliorating its associated neurological sequelae. Summary: There is a need for a global approach to surveillance and prevention of bacterial meningitis. Increasing vaccination coverage with conjugate vaccines against pneumococcus and meningococcus with optimal immunization schedules are high-value healthcare interventions. Additionally, overcoming diagnostic challenges and the early institution of empirical antibiotic therapy and, when feasible, adjunctive steroid therapy constitutes the pillars of reducing the disease burden of bacterial meningitis in resource-limited settings.
RESUMO
Resumen Introducción : La criptococosis meníngea (CM) es una causa frecuente de meningoencefalitis en personas que viven con HIV (PVHIV) y produce una importante morbi-mortalidad (20-55%). Se describen las características clínicas, la letalidad y las variables de mal pronóstico en PVHIV con CM, en unidades de cuidados intensivos (UCI). Métodos : Estudio observacional y retrospectivo. Pe ríodo 21/11/2006 a 24/05/2023. Población evaluada: 154 PVHIV adultos, admitidos en UCI con diagnóstico de CM. Los porcentajes y valores absolutos, fueron comparados mediante Chi-Cuadrado o test de Fisher y las medianas mediante test de Mann-Whitney. La asociación con mortalidad se evaluó por regresión logística. Se utilizó el programa SPSS 23.0. Un valor p<0.05 fue considerado significativo. Resultados : Los pacientes que fallecieron y los que so brevivieron fueron comparables en edad y sexo (p>0.05). El análisis univariado, observó que un estado funcional y nutricional alterado, falta de tratamiento antirretroviral previo (TARV), CD4 <100 células/μl, APACHE II ≥13 y un score pronóstico de PVHIV ≥8 puntos, requerir ventilación mecánica (VM), sufrir insuficiencia respiratoria, renal, disfunción neurológica o sepsis, podrían estar asociados (p<0.05) con mortalidad. La regresión logística estableció que un estado funcional y nutricional alterado, un score pronóstico PVHIV ≥8, necesitar VM y sufrir sepsis serían variables independientes asociadas a mortalidad. Conclusión : Los resultados indican que el estado funcional y nutricional alterado, un score pronóstico PVHIV ≥8 puntos, requerir VM y sufrir sepsis al ingreso a UCI podrían servir como variables independientes para predecir un mayor riesgo de mortalidad.
Abstract Introduction : Meningeal cryptococcosis (MC) is a frequent cause of meningoencephalitis in people living with HIV (PLHIV), leading to substantial morbidity (20- 55%). Clinical characteristics, lethality and adverse prog nostic factors in PLHIV with MC admitted to intensive care units (ICUs) are described. Methods : A retrospective observational study. Period from 11/21/2006 to 05/24/2023. It involved 154 adult PLHIV diagnosed with MC and admitted to ICUs. Percen tages and absolute values were compared by Chi-Square or Fisher's test and medians by Mann-Whitney test. The association with mortality was assessed by logistic re gression. SPSS 23.0 software was used. A p-value <0.05 was considered significant. Results : Patients who died and those who survived were comparable in age and sex (p>0.05). Univariate analysis showed that impaired functional and nutritio nal status, lack of previous highly active antiretroviral therapy, CD4 <100 cells, APACHE II ≥13 and a PLHIV prognostic score ≥8 points, requiring mechanical venti lation (MV), respiratory failure, renal failure, neurological dysfunction or sepsis could be associated (p<0.05) with mortality. Logistic regression established that impaired functional and nutritional status, a PLHIV prognostic score ≥8, need for MV and presence of sepsis would be independent variables associated with mortality. Conclusion : The results indicate that altered functio nal and nutritional status, a PLHIV prognostic score ≥ 8 points, requiring MV and suffering sepsis on admission to the ICU are more frequent in deceased patients, and they could therefore serve as independent variables to predict a higher risk of mortality.
RESUMO
Resumen Streptococcus suis (S. suis) es un patógeno porcino prevalente a nivel mundial, capaz de generar infec ciones en humanos que estuvieron en contacto con el animal o la carne cruda del mismo. Las manifestaciones clínicas comprenden desde casos asintomáticos hasta compromiso sistémico, con una baja mortalidad, pero con la posibilidad de dejar secuelas definitivas como la ataxia e hipoacusia. Son pocos los reportes de casos, debido al descono cimiento de la enfermedad y a su forma atípica de pre sentación. El objetivo de este artículo es relatar el caso de un varón con antecedentes ocupacionales de contacto con porcinos, que ingresó por meningitis y en el cual se obtuvo el aislamiento de S. suis en líquido cefalorra quídeo y hemocultivos pareados; completó tratamiento antibiótico ajustado a la sensibilidad bacteriana, quedó con hipoacusia leve como secuela.
Abstract Streptococcus suis (S. suis) is a globally prevalent swine pathogen, capable of generating infections in humans who were in contact with the animal or its raw meat. Clinical manifestations range from asymptomatic cases to systemic involvement, with low mortality, but with the possibility of leaving definitive sequelae such as ataxia and hearing loss. There are few case reports, due to lack of knowledge of the disease and its atypical presentation. The objec tive of this article is to report the case of a man with an occupational history of contact with pigs, who was admitted for meningitis and in whom the isolation of S. suis was obtained in cerebrospinal fluid and paired blood cultures; He completed antibiotic treatment adjusted to bacterial sensitivity, and was left with mild hearing loss as a consequence.
RESUMO
OBJECTIVES: We aimed to characterize the clinical and radiological features, and outcomes, of a large cohort of hypertrophic pachymeningitis (HP) patients from a single center. METHODS: We conducted a retrospective study at a tertiary referral center, encompassing patients diagnosed with HP between 2003 and 2022. The diagnosis of HP relied on the identification of thickening of the dura mater via magnetic resonance imaging (MRI) of the brain or spine. RESULTS: We included 74 patients with a mean age of 43.6 ± 14.2 years, of whom 37 (50%) were male. Among them, 32 (43.2%) had an immune-mediated origin, including 21 with granulomatosis with polyangiitis (GPA) (predominantly PR3-ANCA positive), four with systemic lupus erythematosus, three with IgG4-related disease, three with idiopathic HP, and one with rheumatoid arthritis. Non-immune-mediated HP accounted for 45 cases (56.8%). Within this category, 21 (28.4%) were infectious cases, with 14 being Mycobacterium tuberculosis infection (TB-HP), and 21 (28.4%) were malignancy-associated HP. Clinical and MRI characteristics exhibited variations among the four etiological groups. Hypoglycorrhachia was primarily observed in infectious and malignancy-associated HP. Immune-mediated HP was associated with a peripheral pattern of contrast enhancement and the Eiffel-by-night sign. MRI features strongly indicative of TB-HP included leptomeningeal involvement, brain parenchymal lesions, and arterial stroke. MPO-ANCA GPA was associated with a higher prevalence of spinal HP. CONCLUSIONS: Within our cohort, GPA and Mycobacterium tuberculosis emerged as the predominant causes of HP. We identified significant disparities in clinical and radiological features among different etiologies, which could have implications for diagnosis.
RESUMO
A 40-year old female chimpanzee (Pan troglodytes) developed hyporexia, weight loss, followed by progressive and complete blindness. Tomography demonstrated an intracranial mass in the rostroventral brain involving the optic chiasm, with a presumptive diagnosis of neoplasm. However, histopathology revealed a granulomatous meningoencephalitis, and tissue samples tested positive for Mycobacterium tuberculosis.

BACKGROUND: Monogenic autoinflammatory disorders result in a diverse range of neurological symptoms in adults, often leading to diagnostic delays. Despite the significance of early detection for effective treatment, the neurological manifestations of these disorders remain inadequately recognized. METHODS: We conducted a systematic review searching Pubmed, Embase and Scopus for case reports and case series related to neurological manifestations in adult-onset monogenic autoinflammatory diseases. Selection criteria focused on the four most relevant adult-onset autoinflammatory diseases-deficiency of deaminase 2 (DADA2), tumor necrosis factor receptor associated periodic fever syndrome (TRAPS), cryopyrin associated periodic fever syndrome (CAPS), and familial mediterranean fever (FMF). We extracted clinical, laboratory and radiological features to propose the most common neurological phenotypes. RESULTS: From 276 records, 28 articles were included. The median patient age was 38, with neurological symptoms appearing after a median disease duration of 5 years. Headaches, cranial nerve dysfunction, seizures, and focal neurological deficits were prevalent. Predominant phenotypes included stroke for DADA2 patients, demyelinating lesions and meningitis for FMF, and meningitis for CAPS. TRAPS had insufficient data for adequate phenotype characterization. CONCLUSION: Neurologists should be proactive in diagnosing monogenic autoinflammatory diseases in young adults showcasing clinical and laboratory indications of inflammation, especially when symptoms align with recurrent or chronic meningitis, small vessel disease strokes, and demyelinating lesions.

El dengue es una enfermedad viral transmitida por la picadura del mosquito Aedes aegypti. El comportamiento del dengue en Argentina es epidémico; la mayoría de los casos se observan en los meses de mayor temperatura. Hasta la semana epidemiológica (SE) 20/2023, se registraron en Argentina 106 672 casos; se vieron afectadas 18 de las 24 provincias que conforman el país. Dentro de los principales grupos de riesgo, se incluyen los menores de 2 años. Reconocer los signos, síntomas e identificar los factores de riesgo es fundamental para el manejo de casos con mayor riesgo de gravedad. Presentamos el caso de una paciente de 32 días de vida que se internó por síndrome febril sin foco, con diagnósticos diferenciales de meningitis viral y sepsis, evolucionó con leucocitosis, plaquetopenia, hipoalbuminemia, asociado a exantema y edemas. Se llegó al diagnóstico de dengue por la clínica, epidemiologia e IgM positiva.
Dengue fever is a viral disease transmitted by the Aedes aegypti mosquitoes. In Argentina, dengue fever is an epidemic disease; most cases are reported during the hot months.Until epidemiological week (EW) 20/2023, 106 672 cases were reported across 18 of the 24 provinces of Argentina. Children younger than 2 years are among the main groups at risk. Recognizing signs and symptoms and identifying risk factors is fundamental for the management of cases at a higher risk of severity. Here we describe the case of a 32-day-old female patient who was hospitalized due to febrile syndrome without a source, who had a differential diagnosis of viral meningitis and sepsis and progressed to leukocytosis, thrombocytopenia, hypoalbuminemia in association with rash and edema. The diagnosis of dengue fever was established based on clinical, epidemiological, and positive IgM data.

BACKGROUND: Ventriculoperitoneal shunt (VPS) represents one of the most classic and widely used treatments for hydrocephalus in pediatric patients. Migration and externalization of the distal end of the catheter through the rectum are extremely rare complications of intestinal perforation with devastating consequences such as meningitis or peritonitis due to enteric bacteria that are significantly life-threatening. Besides, one of the biggest topics with that is that it can happen without producing symptoms, like the patient we present in this case report, which further masks the condition and puts the patient's life more at risk. CASE PRESENTATION: We present a case of a 9-month-old infant patient, with a history of prematurity, tuberculous meningitis (TBM), and hydrocephalus, who came to ED with a functional VPS and the distal end of the catheter protruding outside the rectum for 7 days, without presenting neurological or intestinal symptoms accompanying. One of the parameters that guided the diagnosis and made us suspicious of asymptomatic intestinal perforation (IP) was the background of TMB. The patient was immediately transferred to the OR where both ends of the shunt were removed: in the first instance, the shunt tube was disconnected through the abdomen, thus withdrawing through the anus, and subsequently, the proximal end of the catheter was exteriorized. In turn, the intestinal fistula was successfully repaired laparoscopically, and prophylactic antibiotic treatment was early administered. On the 6th postop day, a shunt was internalized, and a child was discharged on postop day 15 without complications with alarm guidelines. CONCLUSIONS: The authors of this article strongly suggest that (1) anal extrusion of catheters is an uncommon complication but real: for this reason, its development should be considered in all patients with VPS, especially in infants. (2) The patients are often asymptomatic since false tracts can form around the catheter protecting it from spillage, and thus can be removed without complications. (3) Special care should be taken in patients with conditions that increase the risk of developing IP, such as TMB.
