Management and Outcome of a Neurologically Intact Infant with Pierre Robin Sequence and Dandy-Walker Variant Diagnosed with Large Hemispheric Brain Abscess ­ Case Report

Pierre Robin sequence (PRS) is a condition consisting of three essential components: micrognathia or retrognathia, cleft palate, and glossoptosis. It can be part of multiple congenital anomalies. We present the case and outcome of a 3-month-old clinically stable patient who has PRS with Dandy-Walker variant ­ which is a rare presentation in the literature ­ with a large right hemispheric brain abscess, treated with multiple minimally-invasive surgical drainage procedures with adjuvant antibiotics.

Multiple Brain Abscesses by an Air Gun Shot: A Case Report

Introduction Low-velocity penetrating brain injury is not prevalent. In some conditions such as childhood, and with the penetration of a pellet in weak spots of skull, low-velocity penetrating brain injury is expected; however, high-velocity projectiles have also been reported as the cause of severe brain injuries. One of the complications of penetrating brain injury is infection, in which different types ofmicroorganisms play a role. The Streptococcus genus is the leading cause of abscess formation in nontraumatic patients. Multiple brain abscesses are not common. Case Presentation A 10-year-old boy with penetrating brain injury caused by an air gun pellet, who developed signs and symptoms of high intracranial pressure 18 days after the trauma. After the imaging scans and the detection of multiple brain abscesses and severe brain edema, prompt surgical intervention was performed for all three lesions in a single operation. The culture of a pus specimen was positive for Streptococcus species, and, with adequate antibiotic therapy, the patient was discharged from the hospital in good condition. Conclusion Brain injurywith air gun shot is not prevalent. The penetration of a low-velocity air gun pellet in weak points of the skull (such as the orbit, the squamous portion of the temporal bone, and the cranial suture), specially in children, can cause significant brain injuries.

Dyskeratosis congenita and a rare brain abscess / Disqueratosis congénita y absceso del sistema nervioso central

Abstract Dyskeratosis congenita is a rare inheritable disease which causes peculiar dermatological features and bone marrow failure with an increased risk of severe infections and neoplasia. Actinomyces spp. is part of the oral cavity flora. Invasive infections are mostly seen in immunocompromised hosts. We report a case of a rare central nervous infection and an underling inheritable disease.

Resumen La disqueratosis congénita es una enfermedad hereditaria, caracterizada por alteraciones cutáneas y aplasia medular. La principal causa de muerte son las infecciones y el desarrollo de neoplasias. Actinomices spp. son patógenos comensales de la cavidad oral y el tracto urinario, que en raras ocasiones suelen causar infecciones invasivas en el ser humano. Suelen ser más frecuentes en pacientes inmunocomprometidos o con mala higiene dental. Presentamos el caso de una lesión ocupante de espacio a nivel del sistema nervioso central con una inmuno deficiencia heredable.

Brain Abscess Caused by Nocardia: Case Report and Literature Review

Nocardia brain abscess is a rare clinical entity, accounting for 2% of all brain abscesses, associated with high morbidity and amortality rate 3 times higher than brain abscesses caused by other bacteria. Proper investigation and treatment, characterized by a longterm antibiotic therapy, play an important role on the outcome of the patient. The authors describe a case of a patient without neurological comorbidities who developed clinical signs of right occipital lobe impairment and seizures, whose investigation demonstrated brain abscess caused by Nocardia spp. The patient was treated surgically followed by antibiotic therapy with a great outcome after 1 year of follow-up.

Brain Abscess and Esophageal Dilatation: Where is the Link? ­ Case Report

Introduction Caustic substance ingestion is a common cause of esophageal stricture in children. The primary treatment is esophageal dilatation. Although it is known that endoscopic esophageal dilatation is a procedure associated with a high rate of bacteremia, current guidelines do not recommend routine throat swab cultures or antibiotic prophylaxis for the general children population. Case Report We describe a case of a 7-year-old boy presenting with refractory headaches who was diagnosed with cranial abscess after multiple esophageal dilatations due to stenosis caused by caustic soda ingestion. The patient was subjected to neurosurgical intervention and intravenous antibiotic treatment for 6 weeks. Streptococcus viridans culture was positive in purulent abscess content. Conclusion We highlight this condition that, although rare, needs immediate diagnosis and proper treatment. We also recommend routine testing of throat swabs and antibiotics prophylaxis to children undergoing esophageal dilatation.

Absceso cerebral por Nocardia spp. en pacientes inmunocompetentes: presentación de 2 casos / Cerebral abscess by Nocardia spp. in immunocompetent patients: report of 2 cases

Nocardia corresponde a un género de bacterias gram positivo que puede producir compromiso pulmonar, sistémico y abscesos cerebrales, especialmente en pacientes inmunocomprometidos. La infección cerebral por Nocardia spp es extremadamente infrecuente en pacientes inmunocompetentes, por lo cual se reportan dos casos: caso 1: mujer de 61 años, sana, consulta por cefalea y paresia en hemicuerpo izquierdo. Estudio con TAC y RM de encéfalo demuestran absceso cerebral. Se inició tratamiento con ceftriaxona mas cloxacilina y fue drenado quirúrgicamente. En el cultivo del LCR se aisló Nocardia spp. cambiándose esquema a cotrimoxazol con meropenem por 6 semanas. Caso 2: varón de 72 años, hipertenso y tabáquico crónico. Consultó por cefalea, paresia de extremidad inferior derecha y pérdida de visión de ojo derecho. Estudio con TAC y RM de encéfalo objetiva absceso cerebral parietal izquierdo. Se inició tratamiento con ceftriaxona, metronidazol y vancomicina. Se realizó drenaje quirúrgico. El cultivo de absceso resultó positivo para Nocardia spp, ajustándose esquema a cotrimoxazol y meropenem por 6 semanas. Requirió tratamiento prolongado por presentar lenta regresión clínica e imagenoló- gica.

Nocardia is a gram positive bacterial genus. Is involved in pulmonary, systemic and brain abscess usually in immunocompromised patients. Nocardia spp. brain infection is extremely rare in immunocompetent patients, hereby we report 2 cases: case 1: 61 years old woman, without morbid conditions, consulted for headache and left hemiparesis. Study with CT and MRI of encephalon shows brain abscess. Treatment with ceftriaxone plus cloxacilin and surgical drainage were started. In CSF culture, Nocardia spp. was obtained. Scheme was changed to cotrimoxazole with meropenem to complete 6 weeks. Case 2: male of 72 years old, history of smoking and hypertension. Consulted for headache, paresis of right leg and loss of vision of the right eye. CT and MRI showed left parietal brain abscess. Treatment with ceftriaxone, metronidazole and vancomycin were started. Surgical drainage was performed. Abscess culture was positive for Nocardia spp., adjusting scheme to cotrimoxazole and meropenem for 6 weeks. It required prolonged treatment due to slow imaging and clinical regression.

Actinomicosis diseminada con compromiso de sistema nervioso central / Disseminated actinomycosis with central nervous system involvement

Resumen La actinomicosis diseminada es muy infrecuente, así como la afección del sistema nervioso central (SNC) asociada, con mortalidad de hasta 28%. Sus manifestaciones pueden ser similares a cuadros infecciosos de otras etiologías, por lo que el conocimiento de la entidad aumenta la sospecha clínica y permite brindar un tratamiento oportuno. Se presenta el caso clínico de un adulto con edema en una extremidad superior como manifestación de una tromboflebitis y una lesión abscedada axilar, en que se confirmó una infección por actinomicetos. Presentó una diseminación hematógena con compromiso de SNC, de evolución fatal.

Actinomycosis is very rare, as well as the central nervous system (CNS) condition associated with it, presenting a mortality up to 28%. Its manifestations could be similar to infectious conditions from other etiologies, thus, having a better understanding of the entity increases clinical suspicion and also it can provide a timely treatment. The clinical case of an adult with edema in an upper extremity is presented as a manifestation of thrombophlebitis and an abscessed axillary lesion, in which actinomycetes infection was confirmed. He presented a haematogenous spread with CNS involvement, with fatal ending.

A case of thalamic abscess treated by endoscopic surgery.

We report about a 7-year-old female child with cyanotic heart disease whose thalamic abscess was successfully treated by endoscope-assisted abscess drainage. Endoscopic aspiration of thalamic abscess appears to be a safe and effective method of treatment for deep-seated abscesses, as direct visualization of the abscess cavity is possible and the completeness of evacuation can be assessed.

Brain Abscess in children

To find out the clinical presentation, radiological characteristics, various underlying predisposing conditions and causative organisms of brain abscess in children in our setup. Descriptive study. The Children's Hospital and the Institute of Child Health, Lahore, over two years from September 2001 to August 2003. All children [<16 years] presenting with brain abscess were included to study demographic, clinical and radiological features. In addition, attempts were made to find out underlying predisposing conditions and causative organisms. Twenty-five children with brain abscess were managed over 2 years. The mean age was 7.8 years [range 9 months to 16 years]. Male to female ratio was 2.1:1. Most patients [43%] presented with 4 weeks history of illness, with mean duration of illness at presentation of 29.3 days. Main presenting complaints were fever [72%], vomiting [48%], headache [44%] and convulsions [32%]. Five patients [20%] had papilledema at presentation, another 4 [16%] had paresis/paralysis and 3 [12%] had cranial nerve palsies. Majority [64%] had solitary abscess, located in parietal, temporal, frontal and occipital lobes in order of frequency. No underlying predisposing condition was identified in 8 [32%] cases; while 8 [32%] had cyanotic congenital heart disease, 5 [20%] patients had otic infection [mastoiditis], 2 [8%] were postoperative cases and one each developed brain abscess secondary to ventriculo-peritoneal [VP] shunt infection and pulmonary tuberculosis. Causative organisms were isolated in 40% cases, which included Staphylococcus aureus, Staphylococcus epidermidis, Streptococcal species, Klebsiella, E.coli and Proteus. Awareness of predisposing factors, early recognition of clinical features and understanding of the prevalent microbial profile is imperative for better management of children with brain abscess

Pyogenic meningitis: sonographic evaluation.

Forty infants with proven pyogenic meningitis were evaluated by real time cranial sonography. A spectrum of sonographic abnormalities was observed which included echogenic sulci, focal or diffuse increase in parenchymal echoes, ventriculitis, ventriculomegaly with or without aqueductal block, subdural collection, parenchymal infarcts, abscess and subdural empyema. There were two infants with normal sonogram while encephalomalacia was seen in another two patients. An excellent correlation was observed between clinical profile, cerebrospinal fluid biochemistry and sonographic findings.

Interhemispheric empyema. An unusual form of subdural empyema.

A 16 year old male was admitted with a clinical picture suggesting an intracranial pyogenic infection. He also has focal convulsions and left abducens palsy. CT scan showed a subdural empyema with interhemispheric extension. Since the patient was improving clinically, neurosurgical intervention was deferred. Spontaneous interhemispheric empyema is an uncommon condition. In our case conservative management was curative in what is considered a neurosurgical emergency.
