RÉSUMÉ
Nocardia pyomyositis in immunocompetent patients is a rare occurrence. The diagnosis may be missed or delayed with the risk of progressive infection and suboptimal or inappropriate treatment. We present the case of a 48-year-old immunocompetent firefighter diagnosed with pyomyositis caused by Nocardia brasiliensis acquired by direct skin inoculation from gardening activity. The patient developed a painful swelling on his right forearm that rapidly progressed proximally and deeper into the underlying muscle layer. Ultrasound imaging of his right forearm showed a 7-mm subcutaneous fluid collection with surrounding edema. Microbiologic analysis of the draining pus was confirmed to be N brasiliensis by Matrix-Assisted Laser Desorption/Ionization Time-of-Flight (MALDI-TOF) Mass Spectrometry. After incision and drainage deep to the muscle layer to evacuate the abscess and a few ineffective antibiotic options, the patient was treated with intravenous ceftriaxone and oral linezolid for 6 weeks. He was then de-escalated to oral moxifloxacin for an additional 4 months to complete a total antibiotic treatment duration of 6 months. The wound healed satisfactorily and was completely closed by the fourth month of antibiotic therapy. Six months after discontinuation of antibiotics, the patient continued to do well with complete resolution of the infection. In this article, we discussed the risk factors for Nocardia in immunocompetent settings, the occupational risks for Nocardia in our index patient, and the challenges encountered with diagnosis and treatment. Nocardia should be included in the differential diagnosis of cutaneous infections, particularly if there is no improvement of "cellulitis" with traditional antimicrobial regimens and the infection extends into the deeper muscle tissues.

The optimal duration of antibiotic treatment for the most common bacterial meningitis etiologies in the pediatric population, namely Streptococcus pneumoniae, Haemophilus influenzae, and Neisseria meningitidis, is not well-established in the literature. Therefore, we aimed to perform an updated meta-analysis comparing shorter versus longer antibiotic treatment in children with meningitis. PubMed, EMBASE, and Cochrane databases were searched for randomized controlled trials (RCTs) that compared shorter (up to 7 days) versus longer (10 days or double the days of the equivalent short course) duration of antibiotic treatment in children with meningitis and reported the outcomes of treatment failure, death, neurologic sequelae, non-neurologic complications, hearing impairment, nosocomial infection, and relapse. Heterogeneity was examined with I2 statistics. RevMan 5.4.1 was used for statistical analysis and RoB-2 (Cochrane) for risk of bias assessment. Of 684 search results, 6 RCTs were included, with a cohort of 1333 children ages 3 weeks to 15.5 years, of whom 49.51% underwent a short antibiotic course. All RCTs included monotherapy with ceftriaxone, except one, which added vancomycin as well. No differences were found comparing the short and long duration of therapy concerning treatment failure, relapse, mortality, and neurologic complications at discharge and at follow-up. Conclusion: Because no statistically significant differences were found between groups for the analyzed outcomes, the results of this meta-analysis support shorter therapy. However, generalizing these results to complicated meningitis and infections caused by other pathogens should be made with caution. (PROSPERO identifier: CRD42022369843). What is Known: ⢠Current recommendations on the duration of antibiotic therapy for bacterial meningitis are mostly based on clinical practice. ⢠Defining an optimal duration of antibiotic therapy is essential for antimicrobial stewardship achievement, improving patient outcomes, and minimizing adverse effects. What is New: ⢠There are no differences between shorter versus longer antibiotic treatment duration in regard to treatment failure, relapse, mortality, neurologic complications, and hearing impairment at discharge and at follow-up.

A rabdomiólise é uma condição potencialmente grave que pode resultar, dentre outros, da infecção por Influenza. Relatamos o caso de um jovem de 32 anos, sem comorbidades, o qual apresentou febre, mialgia e urina escurecida há quatro dias, seguidas de tosse e coriza. Os exames mostraram elevação significativa da creatinofosfoquinase (64.617U/L) e das transaminases. As principais hipóteses diagnósticas para justificar o quadro foram de etiologia infecciosa, em especial a leptospirose e hepatite viral aguda, antes da confirmação específica da infecção por Influenza A e B. Além de ter sido medicado com ceftriaxona por 10 dias, o paciente recebeu vigorosa e precoce hidratação intravenosa fator que contribuiu, com certeza, para a boa evolução clínica e laboratorial, sem desenvolver lesão renal.

Uncommon forms of syphilis exist, among which neurosyphilis, otosyphilis, and ocular syphilis are included. Neurosyphilis is the infection of the central nervous system caused by Treponema pallidum. The clinical manifestations of neurosyphilis are diverse and include early, late, and atypical forms. Syphilis can affect virtually any ocular structure and can occur at any stage of the disease, as well as otosyphilis. The diagnosis of these conditions is often challenging. However, it is important to consider them as a differential diagnosis, as most of these clinical manifestations are reversible with appropriate antibiotic treatment. A case series study of patients diagnosed with neurosyphilis, otosyphilis, and ocular syphilis, who were admitted to a tertiary-level hospital, is here presented: syphilitic meningitis with cranial nerve involvement, and seizures (case 1), ocular syphilis (case 2), general paresis (case 3), and tabes dorsalis (case 4). Half of the patients presented bilateral sensorineural hearing loss; and also half of the patients had reactive VDRL in cerebrospinal fluid. All were treated with aqueous penicillin G, and in two of these cases, ceftriaxone was chosen to complete ambulatory treatment. One patient had an unfavorable outcome and died (case 1); another was lost in follow-up (case 4); one completely resolved his symptoms (case 2); and another one experienced symptom relapse six months after treatment (case 3).
Existen formas de presentación poco frecuentes de sífilis, dentro de las cuales se incluyen la neurosífilis, otosífilis y sífilis ocular. La neurosífilis es la infección del sistema nervioso central por Treponema pallidum. Las manifestaciones clínicas de neurosífilis son variadas e incluyen formas tempranas, tardías y atípicas. Además, la sífilis puede comprometer prácticamente cualquier estructura ocular, en cualquier etapa de la enfermedad, como así también la otosífilis. El diagnóstico de estas entidades suele ser dificultoso. Sin embargo, resulta importante considerarlas como diagnósticos diferenciales, ya que la mayoría de estas manifestaciones son reversibles con tratamiento antibiótico adecuado. Se presenta una serie de casos de pacientes con diagnóstico de neurosífilis, otosífilis y sífilis ocular, que cursaron internación en un hospital de tercer nivel: meningitis sifilítica con compromiso de pares craneales y convulsiones (caso 1), sífilis ocular (caso 2), paresis general (caso 3) y tabes dorsalis (caso 4). La mitad de los pacientes presentó hipoacusia neurosensorial bilateral. El 50% presentó VDRL reactiva en líquido cefalorraquídeo. Todos fueron tratados con penicilina G sódica y en el 50% se optó por el uso de ceftriaxona como modalidad para finalizar el tratamiento en internación domiciliaria. Respecto a la evolución de los pacientes, uno de ellos falleció como consecuencia del cuadro de neurosífilis (caso 1), otro se perdió en el seguimiento (caso 4) mientras que, de los dos restantes, el caso 3 presentó recaída de su enfermedad a los 6 meses del tratamiento y el caso 2 resolvió ad integrum su sintomatología.

La sialoadenitis crónica esclerosante puede extenderse desde una sialoadenitis focal hasta una cirrosis completa de la glándula. Aparece entre los 40 y 70 años de edad y afecta principalmente a la glándula submandibular. Se asocia con sialolitos y agentes infecciosos inespecíficos. La causa más frecuente de sialolitiasis es la formación de cálculos macroscópicamente visibles en una glándula salival o en su conducto excretor, de los cuales el 80 % al 90 % provienen de la glándula submandibular. Esta predilección probablemente se deba a que su conducto excretor es más largo, más ancho y tiene un ángulo casi vertical contra la gravedad, contribuyendo así a la estasis salival. Además, la secreción semimucosa de la misma es más viscosa. El sitio principal de ubicación de los litos en el conducto submandibular es la región hiliar con un 57 %. La sintomatología típica de la sialolitiasis es el cólico con tumefacción de la glándula y los dolores posprandiales. Reportamos el caso de un paciente masculino de 55 años, quien ingresa al servicio de Cirugía Oral y Maxilofacial del Hospital General Balbuena de la Ciudad de México por presentar un aumento de volumen en la región submandibular izquierda de consistencia dura y dolorosa a la palpación de 15 días de evolución, acompañada de aumento de temperatura en la zona compatible con un absceso. Los estudios de imagen reportan un sialolito en la región hiliar del conducto submandibular de 2,0 x 1,7 x 1,0 cm. Debido a su localización y tamaño, el tratamiento ideal en estos casos es la escisión de la glándula junto con el lito previo drenaje del absceso e inicio de terapia antibiótica doble.
Chronic sclerosing sialadenitis can range from focal sialadenitis to complete cirrhosis of the gland. It appears between 40 and 70 years of age and mainly affects the submandibular gland. It is associated with sialoliths and nonspecific infectious agents. The most common cause of sialolithiasis is the formation of macroscopically visible stones in a salivary gland or its excretory duct, of which 80 % to 90 % come from the submandibular gland. This predilection isprobably due to the fact that their excretory duct is longer, wider and has an almost vertical angle against gravity, thus contributing to salivary stasis. In addition, the semimucous secretion of it is more viscous. The main location of the stones in the submandibular duct is the hilar region with 57 %. The typical symptomatology of sialolithiasis is colic with swelling of the gland and postprandial pain. We report the case of a 55-year-old male patient, who was admitted to the Oral and Maxillofacial Surgery Service of the Hospital General Balbuena in Mexico City due to an increase in volumen in the left submandibular region that was hard and painful on palpation of 15 days of evolution, accompanied by increased temperature in the area compatible with an abscess. Imaging studies report a 2.0 x 1.7 x 1.0 cm sialolith in the submandibular duct hilar region. Due to its location and size, the ideal treatment in these cases is excision of the gland together with the stone previous drainage of the abscess and initiation of dual antibiotic therapy.

Objetivo: Evaluar prevalencia y adecuación de ceftriaxona tras una intervención educativa en un servicio de urgencias.Métodos: Estudio cuasi experimental que incluyó un mues-treo consecutivo de consultas no programadas de pacien-tes adultos, durante dos meses preintervención y posin-tervención. Dicha intervención consistió en capacitación a médicos para limitar su indicación sólo a situaciones clínicas específicas (meningitis, enfermedad pélvica infla-matoria y abdomen agudo). Se utilizaron datos retrospecti-vos, con adicional revisión manual de historias, para validar adecuación de inicio antibiótico y apropiabilidad de droga. Se utilizó estadística descriptiva y analítica.Resultados: De un total de 28.570 consultas, 512 recibie-ron ceftriaxona (1,79%; IC95% 1,64-1,95), y sólo 60,54% se hospitalizaron. En cuanto a la comparación antes-después, se observó una reducción en la tasa de uso (de 3,66% a 0,63%; p<0,001), la adecuación en el inicio de un antimicro-biano se mantuvo (de 84,52% a 86,21%; p=0,778), aunque la adecuación de ceftriaxona aumentó en forma significativa (de 41,78% a 84,00% respectivamente; p<0,001). Adicional-mente, se redujo el tiempo de estadía hospitalaria (media-na de 6 a 5 días; p=0,014), sin diferencias en la mortalidad intrahospitalaria (19,44% vs 17,24%; p=0,691), ni en la mor-talidad a los 30 días (23,41% vs 18,96%; p=0,464).Conclusiones: Esta intervención resultó eficaz. Los hallaz-gos representan un paso fundamental en los programas de optimización del uso de antimicrobianos hospitalarios, que apuntan a reducir su sobreutilización y la consecuente resistencia.
Objective: To evaluate the prevalence and appropriateness of ceftriaxone after an educational intervention in an emergency department.Methods: Quasi-experimental study, which included a consecutive sampling of unscheduled consultations of adult patients, during 2 months pre-intervention and post-intervention. The intervention consisted of training physicians to limit its indication only to specific clinical situations (meningitis, pelvic inflammatory disease, and acute abdomen). Retrospective data were used, with additional manual chart review, to validate appropriateness of antibiotic initiation and drug appropriateness. Descriptive and analytical statistics were used.Results: Among 28570 visits, 512 received ceftriaxone (1.79%; 95%CI 1.64-1.95), and only 60.54% were hospitalized. Regarding the before-after comparison, we observed a reduction in the rate of use (from 3.66% to 0.63%; p<0.001), the appropriateness in starting an antimicrobial was maintained (from 84.52% to 86.21%; p=0.778), and the appropriateness of ceftriaxone increased significantly (from 41.78% to 84.00% respectively; p<0.001). Additionally, hospital length of stay was reduced (median 6 to 5 days; p=0.014), with no difference in in-hospital mortality (19.44% vs 17.24%; p=0.691), nor in 30-day mortality (23.41% vs 18.96%; p=0.464)

El tumor de Pott es una entidad rara, definida como un absceso subperióstico asociado a osteomielitis del hueso frontal. Suele presentarse como complicación de sinusitis aguda o crónica del seno frontal, y se describe con mayor incidencia en población pediátrica, siendo una complicación grave por su alta morbimortalidad. Se presenta a un paciente pediátrico con tumor de Pott y absceso cerebral posterior a una sinusitis aguda de foco odontogénico, en la que los pilares de tratamiento son drenaje quirúrgico precoz y antibioticoterapia prolongada. Se describe la clínica, manejo médico-quirúrgico y seguimiento posterior, ya que, en ausencia de antecedentes, se debe buscar dirigida- mente enfermedad periodontal y realizar un estudio de inmunodeficiencia primaria.
Pott's tumor is a rare entity, defined as a subperiosteal abscess associated with osteomyelitis of the frontal bone. It usually presents as a complication of acute or chronic sinusitis of the frontal sinus and it is described with a higher incidence in the pediatric population, being a serious complication due to its high morbidity and mortality. We present a pediatric patient with Pott's tumor and brain abscess after acute sinusitis of odontogenic focus, in which the pillars of treatment are an early surgical drainage and prolonged antibiotic therapy. The clinic, medical-surgical management and subsequent follow-up are described, since in the absence of antecedents, periodontal disease should be sought directly and a study of primary immunodeficiency performed.

Combination therapy with ampicillin plus ceftriaxone (AMP+CRO) is the first-line therapy for treating severe infections due to Enterococcus faecalis. However, the pharmacokinetic/pharmacodynamic (PK/PD) index linked to the in vivo efficacy of the combination is not yet defined, hindering dose optimization in the clinic. Because classical PK/PD indices are not directly applicable to antimicrobial combinations, two novel indices were tested in the optimized murine model of infection by E. faecalis to delineate the potentiation of AMP by CRO: the time above the CRO threshold (T>threshold) and the time above the AMP instantaneous MIC (T>MICi). The potential clinical relevance was evaluated by simulating human doses of AMP and CRO. Hill's equation fitted well the exposure-response data in terms of T>threshold, with a CRO threshold of 1 mg/L. The required exposures were 46%, 49%, and 52% for stasis and 1- and 2-log10 killing, respectively. Human ceftriaxone doses of 2 g every 12 h (q12h) would reach the target in >90% of strains with thresholds ≤64 mg/L. The AMP T>MICi index also fitted well, and the required exposures were 37%, 41%, and 46% for stasis and 1- and 2-log10 killing, respectively. In humans, the addition of CRO would allow use of lower AMP doses to reach the same T>MICi and to treat strains with higher MICs. This is the first report of the PK/PD indices and required magnitudes linked to AMP+CRO against E. faecalis; these results can be used as the basis to guide the design of clinical trials to improve combined therapy against enterococci.

OBJECTIVE: To evaluate the effect of intravenous (IV) ceftriaxone on free bilirubin concentrations in infants with unconjugated hyperbilirubinemia born at term. STUDY DESIGN: A prospective study was performed with subjects serving as their own controls. Our inclusion criteria were infants born at term <7 days old with sepsis and receiving IV antibiotics for >3 days and resolving hyperbilirubinemia with total serum bilirubin levels between 6 and12 mg/dL by day 4 of life. Free bilirubin concentrations were measured by the peroxidase method using a UB analyzer and a Zone Fluidics device before (baseline) and 15 minutes after (follow-up) IV ceftriaxone administration on postnatal days 4 to 6. Paired measurements of free bilirubin were analyzed using a Student paired t-test or Wilcoxon signed-rank test. RESULTS: In total, 27 infants were studied. The mean free bilirubin (µg/dL) at follow-up was not different from that at baseline when measured by the UB analyzer (P = .78). The mean free bilirubin was significantly lower at follow-up compared with baseline when measured by the Zone Fluidics device (P = .02). The ratio of a free bilirubin with and without ceftriaxone, an index of displacing effect, was 1.02 (95% CI 0.89-1.14) using the UB analyzer and 0.58 (95% CI 0.30-0.86) using the Zone Fluidics device. CONCLUSIONS: Ceftriaxone is not associated with a bilirubin-displacing effect in infants with a mild unconjugated hyperbilirubinemia. Home therapy with once-daily intramuscular ceftriaxone may be an alternative option for management of sepsis in asymptomatic infants with a mild unconjugated hyperbilirubinemia born at term.

Introducción: En de la población adulta predomina la enfermedad pulmonar, pero el coronavirus infantil grave parece más tipificado por una respuesta inflamatoria inmunomediada, con o sin síndrome inflamatorio multisistémico asociado. Objetivo: Examinar un paciente pediátrico con accidente cerebrovascular, como consecuencia de la enfermedad producida por el coronavirus tipo 2. Presentación del caso: Lactante femenina de 6 meses, que se presentó a emergencia con historia de fiebre de 39 oC, sin predominio de horario, de 10 días de evolución que no cedió con antipiréticos tipo acetaminofén, y dificultad respiratoria en los 3 días previos a su presentación en emergencia del hospital. Antecedentes familiares patológicos positivos, por la enfermedad del coronavirus en su padre. En la radiografía de tórax se observó infiltrado alveolar derecho y se ingresó con diagnóstico de neumonía por síndrome respiratorio agudo grave por coronavirus tipo 2. La tomografía de cráneo registró foco isquémico frontal parasagital derecho y parietal izquierdo; posteriormente se confirmó con resonancia magnética, en cuyo informe se definió la presencia de infartos en fase aguda a nivel frontal derecho y parietal izquierdo. Conclusiones: Se expuso una manifestación infrecuente en población pediátrica asociada a la enfermedad por coronavirus. La tasa de eventos tromboembólicos en el curso de las infecciones virales no es baja, y por coronavirus no es la excepción. Se requieren mayores estudios y pruebas para determinar el papel del síndrome respiratorio agudo severo por coronavirus tipo 2 en el accidente cerebrovascular pediátrico(AU)
Introduction: Pulmonary disease predominates in the adult population, but severe infantile coronavirus appears more typified by an immune-mediated inflammatory response, with or without associated multisystem inflammatory syndrome. Objective: To examine a pediatric patient with stroke resulting from coronavirus type 2 disease. Case presentation: 6-month-old female infant presenting to emergency with history of fever of 39 â with no hourly predominance, of 10 days of evolution that did not subside with acetaminophen-type antipyretics and respiratory distress in the three days prior to presentation to hospital emergency. Positive family history of coronavirus disease in his father. Chest X-ray showed right alveolar infiltrate and she was admitted with a diagnosis of severe acute respiratory syndrome pneumonia due to coronavirus type 2. The cranial tomography recorded a right frontal parasagittal and left parietal ischemic focus, later confirmed by magnetic resonance imaging whose report defined the presence of acute phase infarcts at the right frontal and left parietal levels. Conclusions: An infrequent manifestation in pediatric population associated with coronavirus disease is exposed. The rate of thromboembolic events in the course of viral infections is not low and coronavirus is no exception. Further studies and evidence are required to determine the role of severe acute respiratory syndrome due to coronavirus type 2 in pediatric stroke(AU)

Introducción: La insuficiencia adrenal hipotálamo hipofisaria usualmente se manifiesta secundaria a tumores y, cuando resulta congénita se asocia, con frecuencia, con otras deficiencias hormonales. La crisis adrenal suele presentarse en su debut y puede resultar potencialmente mortal. Objetivo: Examinar el caso de una paciente con insuficiencia adrenal central que debutó con una crisis adrenal congénita. Presentación del caso: Recién nacida a término, padres no consanguíneos, hospitalizada a los 9 días de vida por clínica de una semana con múltiples episodios eméticos y apnea. Ingresó con deshidratación severa, hipotensa y estuporosa. Además, se encontró acidosis metabólica severa, hipoglucemia persistente, hiponatremia e insuficiencia prerrenal. Ante la no mejoría de su estado hemodinámico, a pesar del uso de cristaloides y vasopresores, finalmente mejoró con la administración de dosis altas de hidrocortisona. El diagnóstico de deficiencia de cortisol de origen central se realizó con un test dinámico de insulina y la resonancia magnética nuclear hipofisaria. Conclusiones: La crisis adrenal se debe tener presente como diagnóstico diferencial en episodios agudos con inestabilidad hemodinámica persistente e hipoglucemia de difícil manejo. Adicionalmente, hay que considerar que existen otras causas menos comunes de insuficiencia adrenal en neonatos como la hipoplasia hipofisaria(AU)
Introduction: Hypothalamic-pituitary adrenal insufficiency usually manifests secondary to tumors and, when congenital, is often associated with other hormonal deficiencies. Adrenal crisis usually occurs at its onset and can be life threatening. Objective: To review the case of a patient with central adrenal insufficiency who had an onset with a congenital adrenal crisis. Case presentation: Term newborn, non-consanguineous parents, hospitalized at 9 days of life for a week-long clinical presentation with multiple emetic episodes and apnea. She was admitted with severe dehydration, hypotensive and stuporous. In addition, severe metabolic acidosis, persistent hypoglycemia, hyponatremia and prerenal failure were found. Given the lack of improvement of her hemodynamic status, despite the use of crystalloids and vasopressors, she finally improved with the administration of high doses of hydrocortisone. The diagnosis of cortisol deficiency of central origin was made with a dynamic insulin test and pituitary nuclear magnetic resonance imaging. Conclusions: Adrenal crisis should be kept in mind as a differential diagnosis in acute episodes with persistent hemodynamic instability and difficult-to-manage hypoglycemia. Additionally, other less common causes of adrenal insufficiency in neonates, such as pituitary hypoplasia, should be considered(AU)

Introducción: Los neumatoceles y las bulas pulmonares son lesiones que se observan en los niños casi siempre asociadas a neumonías infecciosas, aunque sus causas pueden ser diversas. La importancia clínica de estos procesos radica en el peligro de crecimiento progresivo, que puede comprometer las funciones respiratoria y cardiovascular. Objetivo: Describir las experiencias derivadas del proceso de diagnóstico por imágenes y del tratamiento invasivo de casos atendidos. Presentación de los casos: Desde finales de 2021 y durante un período de un año, se atendieron, en la unidad de cuidados intensivos pediátricos del Hospital Pediátrico Universitario de Cienfuegos, cinco niños con neumonías extensas, que desarrollaron bulas de gran tamaño varios días después del tratamiento antimicrobiano adecuado. Estas necesitaron drenaje y aspiración percutáneos debido a su magnitud y a la presencia de síntomas cardiovasculares. Conclusiones: Las bulas que aparecieron como complicación de la neumonía en el niño pueden presentarse con una frecuencia no despreciable, y hay que mantenerse atentos a su evolución, porque, a diferencia de los neumatoceles, pueden crecer progresivamente y comprometer las funciones respiratoria y cardiovascular. El drenaje percutáneo y aspiración continua por cinco días resultó un método seguro y eficaz para tratar estos procesos(AU)
Introduction: Pneumoatoceles and pulmonary bullae are lesions that are observed in children almost always associated with infectious pneumonia, although their causes may be diverse. The clinical importance of these processes lies in the danger of progressive growth, which can compromise respiratory and cardiovascular functions. Objective: To describe the experiences derived from the imaging process and the invasive treatment of treated cases. Presentation of the cases: Since the end of 2021 and for a period of one year, five children with extensive pneumonia were treated in the pediatric intensive care unit of the University Pediatric Hospital of Cienfuegos, who developed large bullae several days after appropriate antimicrobial treatment. The bullae required percutaneous drainage and aspiration due to their magnitude and the presence of cardiovascular symptoms. Conclusions: The bulla that appeared as a complication of pneumonia in the child can occur with a not negligible frequency, and it is necessary to be attentive to their evolution, because, unlike pneumoatoceles, can grow progressively and compromise respiratory and cardiovascular functions. Percutaneous drainage and continuous aspiration for five days was a safe and effective method to treat these processes(AU)

We report here an atypical case of acute sacroiliitis caused by Erysipelothrix rhusiopathiae revealing tricuspid endocarditis in a 53-year-old woman without medical history. She was admitted to Cayenne hospital because of intense right hip and thigh pain, associated with fever. A right sacroiliitis was visible on the computed tomography (CT) scan, confirmed on MRI. Transesophageal echocardiography revealed a large mobile tricuspid vegetation. Blood cultures were positive for E. rhusiopathiae. CT scan showed pulmonary alveolar opacities, consistent with septic emboli. Clinical improvement was obtained under ceftriaxone followed by ciprofloxacin for 6 weeks of treatment. We present a review of bone and joint infections caused by E. rhusiopathiae. So far, not a single case has been reported in Latin America.

Neisseria meningitidis is a Gram-negative bacterium frequently associated with invasive diseases with high mortality. Although its natural reservoir is the human nasopharynx, in recent years there have been increasing reports of isolation of this agent in the anorectal mucosa, mainly in men who have sex with men (MSM). We present the case of an HIV-positive MSM who consulted for urethritis and primary syphilis, in which N. meningitidis was isolated in an anorectal specimen. He was treated empirically with ceftriaxone and azithromycin, and a post-treatment control culture was negative. Despite the increase in anogenital infections and colonization by N. meningitidis, its role is unknown as a genital pathogen and in the transmission of other infections and the need for specific therapeutic regimens.

Gonorrhea is the second most common sexually transmitted bacterial infection on the planet and is caused by a Gram-negative cocco, Neisseria gonorrhoeae. Currently, the preferred regimen for the management of this disease in Brazil is a combination of antimicrobials, in this case, ceftriaxone and azithromycin. However, over time, the gonococcus developed a decrease in susceptibility to the regimen used, which resulted in frank resistance to antimicrobials, progressively reducing the therapeutic options available. Thus, the study presented here aims to analyze and discuss the current scenario of resistance of N. gonorrhoeae to the antimicrobials used to date, to encourage discussion on the subject in the academic environment. For this purpose, 47 articles indexed in the Bireme, PubMed, Scielo and UpToDate platforms were selected.

BACKGROUND: Active-controlled noninferiority studies are used to investigate novel agents for uncomplicated urogenital gonorrhea (uUGC) as placebo-controlled trials are unethical. A systematic literature review and meta-analysis were conducted to estimate the ceftriaxone and proxy-for-placebo microbiological treatment effect and determine an appropriate noninferiority margin for phase 3 trials. METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. To account for interstudy variability, a weighted, noniterative random-effects model was fitted using "R" software to estimate the microbiological response rate and 95% confidence intervals (CIs) for ceftriaxone and proxy-for-placebo (treatment with an antibiotic the isolate was subsequently confirmed resistant to, or spontaneous resolution without treatment). I2 , τ2 , and P values were computed and included in the meta-analysis forest plot. RESULTS: Seventeen studies were included in the meta-analysis; 14 reported ceftriaxone response in micro-intent-to-treat and microbiologically evaluable populations, and 3 reported proxy-for-placebo treatment response in uUGC (microbiologically evaluable population only). Microbiological treatment effect was estimated by subtracting the upper end of the CI for placebo from the lower end of the CI for ceftriaxone. Overall microbiological response was 98% (95% CI, 97-99) for ceftriaxone and 44% (95% CI, 34-54) for proxy-for-placebo, resulting in a microbiological treatment effect of 43%. A noninferiority margin of 15% preserved 65% of the ceftriaxone treatment effect, exceeding the 50% recommended per US Food and Drug Administration guidance for noninferiority studies. CONCLUSIONS: Results of this systematic literature review and meta-analysis could help inform the design, conduct, and analysis of future clinical studies in uUGC.

Resumen Neisseria meningitidis es una bacteria gramnegativa asociada frecuentemente a enfermedades invasoras de elevada mortalidad. Si bien su reservorio natural es la nasofaringe humana, en los últimos años han aumentado los aislamientos de este agente en la mucosa anorectal, principalmente en hombres que tienen sexo con hombres (HSH). Presentamos el caso de un HSH con infección por VIH, que consultó por un cuadro de uretritis y sifilis primaria, en el cual se aisló N. meningitidis en una muestra anorectal. Fue tratado en forma empírica con ceftriaxona y azitromicina, realizándose un cultivo de control post-tratamiento que fue negativo. A pesar del aumento de las infecciones y colonizaciones anogenitales por N. meningitidis, se desconoce su rol como patógeno genital, en la transmisión de otras infecciones y la necesidad de esquemas terapéuticos específicos.

El Streptococcus gallolyticus del colon. La fisiopatología que explica este fenómeno implica el aumento local de niveles de lactato puede presentarse como el germen causal de la endocarditis infecciosa en pacientes con lesiones premalignas y malignas, colágeno, fibrinógeno y fibronectina secundario a la hiperactividad metabólica tumoral que genera un ambiente adecuado para el crecimiento y adhesión bacteriana a la pared intestinal y posterior translocación al torrente sanguíneo. Simultáneamente, se establece la presencia de infecciones secundarias por la formación de biofilms, tanto a nivel colorrectal como en válvulas cardíacas. El objetivo del manuscrito es un mapeo en la literatura médica disponible sobre la correlación entre la endocarditis por Streptococcus gallolyticus y las lesiones premalignas y malignas de colon. Simultáneamente, exponer la experiencia clínica de un hombre de 82 años con diagnóstico de endocarditis por Streptococcus gallolyticus y el hallazgo incidental de pólipos adenomatosos del colon(AU)
Streptococcus gallolyticus can present as the causative germ of infective endocarditis in patients with premalignant and malignant lesions of the colon. The pathophysiology that explains this phenomenon involves the local increase in lactate that can be presented as the causal germ of infective endocarditis in patients with premalignant and malignant lesions, collagen, fibrinogen, and fibronectin levels secondary to tumor metabolic hyperactivity, which generates a suitable environment for bacterial growth and adhesion to the intestinal wall and subsequent translocation to the bloodstream. Simultaneously, the presence of secondary infections is established due to the formation of biofilms, both at the colorectal level and in the heart valves. The objective of the manuscript is a mapping in the available medical literature on the correlation between Streptococcus gallolyticus endocarditis and premalignant and malignant colonic lesions. Simultaneously, to present the clinical experience of an 82-year-old man diagnosed with Streptococcus gallolyticus endocarditis and the incidental finding of adenomatous polyps of the colon(AU)
