[Epidural extraskeletal Ewing sarcoma. Case report and literature review]. / Sarcoma de Ewing extraesquelético epidural. Caso clínico y revisión de la literatura.

Ewing sarcoma is a malignant tumour of the bone that sometimes presents extraskeletal involvement, with the epidural location being rare. We report the case of a 45-year-old woman with paresthesia, paresis and urinary retention. Magnetic resonance imaging showed an epidural mass from C6 to D3. Laminectomy from C7 to D2 and partial resection of the lesion was performed. Pathological analysis was consistent with Ewing sarcoma. The patient received chemotherapy and radiotherapy, without evidence of disease at 8 months follow-up. A review of the literature on all published cases of extraskeletal Ewing sarcoma with epidural involvement is presented.

Diagnosing external ventricular drain-related ventriculitis by means of local inflammatory response: soluble triggering receptor expressed on myeloid cells-1.

INTRODUCTION: External ventricular drainage (EVD)-related ventriculitis is one of the most severe complications associated with the use of EVDs. Establishing an early and certain diagnosis can be difficult in critically ill patients. We performed this prospective study to evaluate the usefulness of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) determination in cerebrospinal fluid (CSF) in the diagnosis of ventriculitis. METHODS: A prospective observational study was conducted of 73 consecutive patients with EVD. Samples of CSF for culture, cytobiochemical analysis and sTREM-1 determination were extracted three times a week. Ventriculitis diagnosis required a combination of microbiological, cytobiochemical and clinical criteria. RESULTS: Seventy-three consecutive patients were included. EVD-related ventriculitis was diagnosed in six patients and EVD-colonization in ten patients. Patients without clinical or microbiological findings were considered controls. The median CSF sTREM-1 was 4,320 pg/ml (interquartile range (IQR): 2,987 to 4,886) versus 266 pg/ml (118 to 689); P <0.001. There were no differences when comparing colonized-patients and controls. The best cut-off sTREM-1 value for the diagnosis of ventriculitis was 2,388.79 pg/ml (sensitivity 100%, specificity 98.5%, positive predictive value 85.71%, negative predictive value 100%). CSF proteins, glucose and the ratio CSF/serum glucose were also significantly different (P = 0.001). Serum biomarkers were not useful to diagnose EVD-related infection. These results were confirmed by a case-control study with ventriculitis patients (cases) and non-ventriculitis (control subjects) matched by age, comorbidities, severity scales and EVD duration (P = 0.004). CONCLUSIONS: CSF sTREM-1 was useful in the diagnosis of ventriculitis, in a similar measure to classical CSF parameters. Furthermore, CSF sTREM-1 could prove the diagnosis in uncertain cases and discriminate between EVD-colonization and infection.

Sonographic pathoanatomy of greater trochanteric pain syndrome.

AIMS: To identify and highlight pertinent US features that could serve as imaging biomarkers to describe different patient phenotypes, within Great Trochanteric Pain Syndrome (GTPS) clinical diagnosis. MATERIALS AND METHODS: Using ultrasound we evaluated eighty-eight clinically diagnosed patients with GTPS, for tendon matrix changes and calcium deposits in the gluteus medius (superoposterior and lateral aspects) and in the gluteus minimus. Peritrochanteric examination included fascia lata, trochanteric bursa, cortical irregularities and the presence of enthesophytes. The association of pathological changes with pain and functionality was evaluated using multivariate regression models. RESULTS: Out of the 88 patients, 86 examinations (97.7%) detected gluteus medius tendinopathy, and 54 patients (61.4%) had gluteus minimus tendinopathy in addition. Calcium deposits were present in 97.7% of patients, associated with tenderness (p = 0.009), and most often located in the gluteus medius rather than in the gluteus minimus (p = 0.014); calcifications were associated with tendon thickness (p = 0.042), hypoechogenicity (p = 0.005) and the presence of partial tears (p = 0.030). Bursa swelling occurred in 36 patients (40.9%); multivariate regression models predicted less pain in patients with bursa distension (p = 0.008) and dysfunction in patients with gluteal muscle atrophy (p = 0.001) and loss of fibrillar pattern in the gluteus medius (p = 0.002). CONCLUSION: GTPS involves both degenerative calcifying gluteal tendinopathy and alterations in the peritrochanteric space associated with physical function and pain. The severity of GTPS can be assessed using ultrasound imaging biomarkers.

[Limiting ICU admission from emergency services and wards]. / Limitación del ingreso en unidades de cuidados intensivos desde los servicios de urgencias y las plantas de hospitalización.

INTRODUCTION: Decisions not to admit a patient to intensive care units (ICU) as a way of limiting life support treatment (LLST) is a practice that can affect the operation of the emergency services and the way in which patients die. METHODS: Post hoc analysis of the ADENI-UCI study. The main variable analysed was the reason for refusal of admission to the ICU as a measure of LLST. For the present post hoc analysis, the registered patients were divided into 2 groups: the patients assessed in the intensive medicine services from the emergency department and the patients assessed from the conventional hospitalization areas. Student t was used in the comparative statistics when the mean values of the patient sub-cohorts were compared. Categorical variables were compared with the χ2 tests. RESULTS: The ADENI-ICU study included 2,284 decisions not to admit to the ICU as a measure of LLST. Estimated poor quality of life (p=.0158), the presence of severe chronic disease (P=.0169) and futility of treatment (P=.0006) were percentage decisions with greater weight within the population of hospitalized patients. The percentage of disagreement between the consulting physician and the intensivist was significantly lower in patients assessed from the emergency services (P=.0021). CONCLUSIONS: There are appreciable differences in the reasons for consultation, as well as in those for refusal of admission to an ICU between the consultations made from an emergency department and a conventional hospitalization facility.

[Decisiones de no ingreso en las Unidades de Cuidados Intensivos como medida de limitación de los tratamientos de soporte vital: variabilidad geográfica en España]. / Decisions of refusal intensive Care Units' admission as a measure of limitation of life support treatments: geographical variability in Spain.

From a post hoc analysis of the ADENI-UCI study (multicenter, observational, cohort, prospective study, with a follow-up period of 13 months, in 62 Intensive Medicine Services in Spain. geographical differences in the reason for denial of income in UCI as a LTSV measure are analyzed. A total of 2284 with an average age of 75.25 (12.45) years were included. 59.43% male. By means of multinominal regression adjusted by age, sex, APACHE and SOFA, was evident (by choosing the northern for reference) that age in the south was a less significantly exposed reason (OR: 0.48 (IC95%: 0.35-0.65). p.

Multiple filum terminale hemangioblastomas symptomatic during pregnancy. Case report.

Hemangioblastomas are low-grade, highly vascular tumors commonly associated with von Hippel-Lindau (VHL) syndrome and most often appearing in the cerebellum. They very rarely occur in the spinal nerve roots, and an origin in the filum terminale is exceptional with no instances of multiple hemangioblastomas of the filum terminale reported in the literature. Because of their vascular nature, these lesions can enlarge and become symptomatic in the context of the changes that take place during pregnancy, as has been noted with cerebellar hemangioblastomas. In any case, the evolution of spinal hemangioblastomas during pregnancy is not well known given its rarity. The conjunction of both processes--that is, multiple hemangioblastomas arising in the filum terminale and pregnancy--is unique. The authors describe the case of a 41-year-old woman with multiple hemangioblastomas of the filum terminale and no other evidence of VHL syndrome, in whom pregnancy precipitated symptoms. The interruption of gestation led to a remission of the symptoms. The literature concerning filum terminale hemangioblastomas and pregnancy is also reviewed.

A través de un análisis post hoc del estudio ADENI-UCI (estudio multicéntrico, observacional, de co-hortes, prospectivo, con un período de seguimiento de 13 meses, en un total de 62 servicios de MedicinaIntensiva en España; se analizan las diferencias geográficas del motivo de negación de ingreso en UCI comomedida de LTSV. Se incluyeron 2284 pacientes con una edad media de 75,25 (12,45) años. El 59,43% varones.Mediante regresión multinominal ajustada por edad, sexo, APACHE II y SOFA, se evidenció (al elegir lazona norte como referencia) que la edad en la zona sur fue un motivo menos expuesto de forma significati-va (OR: 0.48 (IC95%: 0.35-0.65). p<0,001), que la enfermedad crónica severa era menos valorada en la zona mediterránea (OR: 0.70 (IC95%: 0.56-0.87). p=0,001), mientras que presentaba más peso en la zona centro(OR: 1.78 (IC95%: 1.43-2.23). p<0,001). La limitación funcional previa fue el motivo más esgrimido en regio-nes centro y sur (OR: 1.39, (IC95%: 1.12-1.72). p=0,002; OR: 1.50, (IC95%:1.15-1.94). p=0,002). Fue la futilidaden el tratamiento el motivo que mayores diferencias presentó entre las diversas regiones analizadas (dif:37,2%-68,8%). Por lo tanto, se puede concluir que existen diferencias geográficas en el territorio españolen las decisiones de rechazar el ingreso en una UCI como medida de LTSV, probablemente justificadas pordiferencias organizativas de los servicios de medicina intensiva participantes en el ADENI-UCI.(AU)

A comparison of screening batteries in the detection of neurocognitive impairment in HIV-infected Spanish speakers.

BACKGROUND: A substantial number of Spanish-speaking individuals from Mexico and Central America are now living in the United States. These individuals are at heightened risk for HIV infection and, due to late diagnosis and limited resources, for HIV-associated neurocognitive disorders (HAND). Early detection is key, yet adequate methods for detecting HAND in Spanish speakers, especially in resource-poor areas, remains problematic. Therefore, it is necessary to identify accurate yet efficient neurocognitive screening tools that are appropriate for use in resource-limited AIDS clinics serving Spanish-speaking patients. METHODS: Twenty-one Spanish-speaking, HIV-positive adults who migrated from Mexico or Central America underwent neuromedical and neurocognitive evaluation in Spanish. The concordance of three neurocognitive screening measures (the HIV Dementia Scale [HDS], the Mini-Mental State Examination [MMSE], and the NEUROPSI) with a comprehensive neuropsychological battery was examined. In addition, accuracy in detecting neurocognitive impairment using standard and alternative cutoff scores was examined. RESULTS: The HDS and the NEUROPSI showed high correlation with the comprehensive neuropsychological battery. The HDS and the NEUROPSI also had the highest sensitivity (67% and 75%, respectively) and specificity (50% and 38%, respectively). Both measures also showed greater sensitivity than the MMSE to very mild forms of HAND. CONCLUSION: In this small sample of HIV-positive Spanish speakers from Mexico and Central America living in the United States, the HDS and the NEUROPSI demonstrated reasonable accuracy in detecting neurocognitive impairment, while the MMSE demonstrated very poor accuracy. The HDS and the NEUROPSI were equally sensitive in detecting mild HAND. Continued test development is required to capture this disorder, especially in resource-limited settings.
