AbstractAbstract
[en] Neuromyelitis optica is a demyelinating disease that mainly affects the optic nerve and the spinal cord, which generally produces recurrent outbreaks that cause severe disability. There are few epidemiological studies about this disease, with a single study in Central America in the country of Panama with cases provided by neurologists from that country. There are no epidemiological studies of optic naturalism published in Costa Rica at present. The list of patients with the diagnosis of Neuromyelitis optica, other demyelizing diseases and Unspecified demyelizing disease of the Central Nervous System were requested, during the period from August 2011 to December 2015 from the Statistics services of the Hospitals that have adult neurologists ; specifically: San Juan de Dios Hospital, Tony Facio Hospital, Heredia Hospital, Calderon Guardia Hospital, Mexico Hospital, Max Peralta Hospital, San Carlos Hospital, San Rafael de Alajuela Hospital, Escalante Pradilla Hospital and Monsenor Sanabria Hospital. Subsequently, those patients who met the criteria for optic neuromyelitis published in 2006 were included. The total number of patients with a diagnosis of optic neuromyelitis from August 2011 to December 2015 was 40, with an approximate frequency of 1.2 per 100,000 inhabitants. Of these 40 patients, 62% (25) of the patients were female and 38% (15) male, with a male / female ratio of 1: 1.6. The number of patients by province was as follows: Puntarenas 2, Limon 3, Guanacaste 1, San Jose 18, Alajuela 7, Cartago 6 and Heredia 3. While the diagnosis time after the first outbreak presented a median of 2 years. The number of seropositive patients for AQP-4 (Aquaporin 4) was 15, 8 patients were seronegative and 17 had not been tested. Most of the patients had recurrent type optic neuromyelitis (97.5%) and only one patient had a monophasic disease. Some patients with Neuromyelitis optica associated other diseases, such as Sjogren in one patient, intermittent Acute Porphyria in one patient, hypothyroidism in 3 patients, Thrombotic Thrombocytopenic Purpura in one case, and Systemic Lupus erythematosus and Anti phospholipid Syndrome in the same patient. The frequency of neuromyelitis optica in CCSS in people older than 13 years was higher than expected. Despite not having anti-AQP4 antibodies in the institution, the non-inclusion of patients from private hospitals, the underdiagnosis and the lack of a spectrum diagnosis of NMO (Neuromyelitis optica) due to the absence of antibodies.

La Neuromielitis optica es una enfermedad desmielinizante que afecta principalmente el nervio optico y la medula espinal, la cual produce generalmente brotes recurrentes que causan discapacidad severa. Existen escasos estudios epidemiologicos acerca de esta enfermedad , con un unico estudio en Centroamerica en el pais de Panama con casos provistos por neurologos de dicho pais. No existen estudios epidemiologicos de Neuromelitis optica publicados en Costa Rica en la actualidad. Se solicitaron la lista de pacientes con el diagnostico de Neuromielitis optica, otras enfermedades desmielizantes y Enfermedad desmielizante del Sistema Nervioso Central no especificada, durante el periodo de agosto 2011 a diciembre del 2015 a los servicios de Estadistica de los Hospitales que cuentan con neurologos de adultos; especificamente : Hospital San Juan de Dios, Hospital Tony Facio, Hospital de Heredia, Hospital Calderon Guardia, Hospital Mexico, Hospital Max Peralta, Hospital de San Carlos, Hospital San Rafael de Alajuela, Hospital Escalante Pradilla y Hospital Monsenor Sanabria. Posteriormente, se incluyeron aquellos pacientes que cumplieran los criterios de neuromielitis optica publicados en el 2006. El numero total de pacientes con diagnostico de Neuromielitis Optica de Agosto de 2011 a Diciembre del 2015 fueron 40, con una frecuencia aproximada de 1.2 por 100000 habitantes. De estos 40 pacientes, el 62% (25) de los pacientes eran mujeres y 38% (15) hombres, con un radio hombres/mujeres 1:1.6. El numero de pacientes por provincia fue el siguiente: Puntarenas 2, Limon 3, Guanacaste 1, San Jose 18, Alajuela 7, Cartago 6 y Heredia 3. Mientras que el tiempo de diagnostico posterior al primer brote presento una mediana de 2 anos . El numero de pacientes seropositivos para AQP-4 (Aquaporin 4) fue 15, 8 pacientes eran seronegativos y 17 no se habia realizado la prueba. La mayoria de los pacientes presentaba una neuromielitis optica de tipo recurrente (97.5%) y solo un paciente tenia una enfermedad monofasica. Algunos pacientes con Neuromielitis optica asociaban otras enfermedades, tales como Sjogren en un paciente, Porfiria Aguda intermitentes en un paciente, hipotiroidismo en 3 pacientes, Purpura Trombocitopenica Trombotica en un caso y Lupus eritematoso sistemico y Sindrome Antifosfolipido en un mismo paciente. La frecuencia de neuromielitis optica en la CCSS en personas mayores de 13 anos fue mayor a lo esperado. A pesar de no contar con los anticuerpos anti-AQP4 en la institucion, la no inclusion de pacientes de hospitales privados, el sub diagnostico y la falta de diagnostico de espectro de NMO (Neuromielitis optica) por ausencia de anticuerpos.

AbstractAbstract
[en] Background: Acute disseminated encephalomyelitis (ADEM) may be a rapidly progressive disease with different clinical outcomes. Purpose: To investigate the radiological findings of fulminant ADEM on diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery (FLAIR) images, and to correlate these findings with clinical outcome. Material and Methods: Initial and follow-up magnetic resonance imaging (MRI) scans in eight patients were retrospectively evaluated for distribution of lesions on FLAIR images and presence of hemorrhage or contrast enhancement. DWI of the patients was evaluated as to cytotoxic versus vasogenic edema. The clinical records were analyzed, and MRI results and clinical outcome were correlated. Results: Four of the eight patients died, three had full recovery, and one had residual cortical blindness. The distribution of the hyperintense lesions on FLAIR sequence was as follows: frontal (37.5%), parietal (50%), temporal (37.5%), occipital (62.5%), basal ganglia (50%), pons (37.5%), mesencephalon (37.5%), and cerebellum (50%). Three of the patients who died had brainstem involvement. Two patients had a cytotoxic edema, one of whom died, and the other developed cortical blindness. Six patients had vasogenic edema: three of these patients had a rapid progression to coma and died; three of them recovered. Conclusion: DWI is not always helpful for evaluating the evolution or predicting the outcome of ADEM. However, extension of the lesions, particularly brainstem involvement, may have an influence on the prognosis

AbstractAbstract
[en] In 1981, Currarino et al described a triad of findings that consist of partial sacral dysgenesis, presacral mass (anterior meningocele, enteric cyst, or presacral teratoma) and anorectal malformation. Currarino syndrome exhibits variable expressivity and the clinical presentation tends to vary with the age of the subject such as spinal anomaly detected in the fetus, imperforate anus in the newborn, and intractable constipation or neurologic symptoms in the infant and older child. At any age, meningitis can be the presenting symptom and imaging is required for proper investigation. Meningitis, sepsis, urinary tract infections, and, rarely, malignant transformation of a teratoma are serious potential complications. This pictorial review describes the imaging findings, clinical history, surgical interventions, and genetic background in 5 children with this syndrome who presented in our hospital in the interval of 1 year.

AbstractAbstract
[en] The relationship between morphological changes in the spinal cord shown on computer-assisted myelography and symptoms was investigated in 73 patients with cervical spondylotic myelopathy. Flatness of the spinal cord was seen in many of the patients. Symptoms were likely to be severer with increasing the degree of flatness of the spinal cord. The length of the flat spinal cord will help to select the operative method for cervical spondylotic myelopathy. (Namekawa, K.)

AbstractAbstract
[en] Computed Tomography (CT) of the spine was performed on 17 patients with myeloma in order to assess the role of the technique in recognizing and evaluating the extent of the lesions. Myelomatous lesions followed two patterns at CT: first of all, multiple focal lesions, whose density is either solid, liquid, or fatty; second, an extensive pattern involving the spongiosa of the vertebra, including the posterior arch. CT detected more lesions than conventional radiology; furthermore, the extent of the lesions was much better demonstrated by CT. CT should thus be performed: a) in case of pain and/or neurological findings in negative radiological examinations; b) to evaluate the extent of myelomatous lesions (mainly in the spine); c) in solitary myeloma CT may be performed on different bone segments with clinical symptomatology but normal X-ray findings

AbstractAbstract
[en] Full text: Skull base osteomyelitis is the infection that has spread to the skull base, beyond the external auditory canal and seen in advanced stage of malignant otitis externa. Early diagnosis of this condition includes the use of bone scintigraphy since clinical assessment alone cannot differentiate the skull base osteomyelitis from the severe type of otitis externa in which there is no extension to the adjacent bone. Objective: To determine the role of three phase bone scintigraphy and delayed SPECT/CT in detection of skull base osteomyelitis in patients with malignant otitis externa. Material and Methods: Clinical records of 20 patients (14 Males and 6 Females; mean age 72 yrs) of otitis externa with suspected skull base involvement referred for bone scintigraphies were analyzed retrospectively. Three phase bone scintigraphy was acquired under dual detector gamma camera after intravenous injection of 20 mCi (740 MBq) 99mTc-MDP followed by SPECT/CT of the skull. Scintigraphic findings were compared with clinical symptoms, signs and diagnostic CT scan findings. Results: All the patients except one were diabetic and having elevated ESR. 18 patients presented with bilateral symptoms and rest unilateral. Cranial nerves were involved in 8 patients (40%). Ear discharge culture sensitivity report was found in three patients; it was positive for Pseudomonas aeruginosa for two patients and in Diptheroids for one. In 9 patients (45%) increased flow of tracer and 10 patients (50%) increased blood pool phase in the temporal region was found. Delayed phase images showed increased uptake in skull bone in 19 patients (95%). Hybrid SPECT/CT of the skull localized areas of increased tracer uptake to the mastoid part in 15 patients (75%), petrous part in 11 patients (55%), sphenoid in 3 patients (15%) and zygomatic bone in one patient (5%) with CT showing destructive changes in 5 patients (25%) which were corroborated with diagnostic CT findings. SPECT/CT along with three phase bone scan findings were suggestive of active inflammation in 10 patients (50%) which changed the management in 5 patients (25%). Conclusion: Three phase bone scintigraphy and Hybrid SPECT/CT is a sensitive modality in detection of skull base osteomyelitis in cases of malignant otitis externa
