Giant extracranial liposarcoma: Case report

Objective: Anaplastic liposarcoma of the head is an extremely rare entity. Seventy-seven cases of head and neck liposarcomas have been reported in the world literature since 1911. Radical surgery is the form of treatment advised.Clinical presentation: Authors report the case of a 62 years old female patient admitted in our institution for a giant extracranial tumor (122/88 mm), developed insidious over a period of 3 years and neglected. The patient agreed surgery only for the epicranial tumor. The lesion was completely removed. Postoperatory outcome was excellent concerning this tumor, although the histopathological result was not that great: high anaplastic liposarcoma.Conclusion: Liposarcoma of the scalp is rare. Diagnosis is made histologically. The histopathologic variant influences clinical behavior and prognosis. The treatment of choice is wide surgical excision.&nbsp

Update on the natural history of infratentorial cavernous malformations

Infratentorial cavernous malformations are still a source of serious controversies in neurosurgery and their natural history and treatment are intensely debated in literature. Recent studies suggest that symptomatic infratentorial cavernous malformations have a more aggressive clinical outcome than the supratentorial ones (the risk of hemorrhage is approximately 30 times that of the supratentorial cavernomas) The optimal therapeutic approach of infratentorial cavernomas need a good understanding of the natural history and also the characteristics that may influence the associated neurological risk, like the patient status at admission, the localization and the genetics of the malformation. Many studies have been published in the last decades to enlight the clinical aspects and the natural history of these vascular malformations. The purpose of this analysis is to make a literature review of the morbidity risk associated to cavernous malformations and their influence on the treatment plan

Brain abscesses: management and outcome analysis in a series of 84 patients during 12 year period

Authors analyze 84 cases of brain abscesses operated between January 2000 and December 2011, in the Fourth Neurosurgical Department by the same surgical team. We underline the general series profile: the mean age was 42.96 years (range: 11-75 years old), 72.62% were males, association with heart defects in seven cases (8.33%), positive bacteriological examination for germs in only 37 cases (44.04%), all negative for HIV infection. The median number of days to diagnosis was 9. Most frequent clinical presentations included headache (40.47%), fever (35.71%), focal neurologic deficits (29.76%), increased intracranial pressure (28.57%) and seizures (11.90%).The majority of cases (76.19%, n=64) presented a supposed medical condition favoring dissemination of a previous infection: malnutrition, tuberculosis, chronic alcoholism, chronic liver malady, neglected dental or ear infections, and only 5 cases (5.95%) had been diagnosed with secondary immunodeficiency syndromes following autoimmune systemic diseases.According to our treatment policy all cases except for two (treated by puncture and aspiration) benefited of open surgery and total removal of the lesions, without local recurrence. Outcome was favorable in 82.14% (n=69) of subjects. General morbidity was 26.19%, and mortality stood at 7.14%. Six cases remained with permanent motor deficit (7.14%) and four (4.76%) with controllable seizures. Out of a total of 33.33% (n=28) of complications, 64.28% were due to medical causes.Follow-up had been extended up to three years for at least 2/3 of patients, who resolved in time medical or surgical conditions which determined cerebral dissemination of the infection. Despite of a poor medical and biological condition, the patients with brain abscess outside of HIV infections benefit from neurosurgical adequate treatment, and if supportive medical and general therapy is continued and sustained, the healing and survival in good neurological status is the rule. Hematogenous spread and advance age were predictors of poor prognosis. Our findings are similar to the results of recent works, although in our series, there is a higher frequency of aerobe germs

Influence of feeding graded levels of canned sardines on the inflammatory markers and tissue fatty acid composition of Wistar rats

The present study was supported by Fundacao para a Ciencia e a Tecnologia (FCT) through the grant PTDC-SAU/OSM/2006/70560 (principal investigator: P. O. R). S. V. M. is the recipient of a FCT individual fellowship SFRH/BPD/2009/63019 and P. A. L. is a researcher involved in the FCT programme 'Ciencia 2008'.Canned sardines are a ready-to-use fish product with excellent nutritional properties owing to its high n-3 long-chain PUFA content, mainly EPA (20 : 5n-3) and DHA (22 : 6n-3). The present study aimed to assess the effect of two dosages of canned sardines, recommended for the primary and secondary prevention of human CVD, on the inflammatory marker concentrations and fatty acid composition of erythrocytes and key metabolic tissues (liver, muscle, adipose tissue and brain) in the rat model. Wistar rats were fed a diet containing 11\% (w/w) of canned sardines (low-sardine (LS) diet) and a diet containing 22\% (w/w) of canned sardines (high-sardine (HS) diet) for 10 weeks. Daily food intake, weight gain, and organ and final body weights were not affected by the dietary treatments. The concentrations of total cholesterol, HDL-cholesterol and LDL-cholesterol decreased in both the LS and HS groups, while those of alanine aminotransferase and adiponectin increased. The concentrations of IL-1 beta increased only with the highest dosage of sardine. The dose-dependent influence of the graded levels of EPA+DHA was tissue specific. Compared with that of other tissues and erythrocytes, the fatty acid composition of the brain was less affected by the canned sardine-supplemented diets. In contrast, the retroperitoneal adipose tissue was highly responsive. The deposition ratios of EPA and DHA indicated that the LS diet was optimal for DHA deposition across the tissues, except in the retroperitoneal adipose tissue. Taken together, our findings indicate that a LS diet positively affects plasma lipid profiles and inflammatory mediators, whereas a HS diet has contradictory effects on IL-1 beta, which, in turn, is not associated with variations in the concentrations of other pro-inflammatory cytokines. This finding requires further investigation and pathophysiological understanding.publishersversionpublishe

Deontological issues - possible misdiagnosis of cerebral metastases

Authors analyses a number of 4588 (52, 24% over 50 years old) patients operated for cerebral tumors in the Clinic Emergency Hospital “Bagdasar-Arseni” from Bucharest, between 2000-2010, with peculiar attention to the concordance between the preoperative and postoperative diagnosis, related to the actual policy to evaluate a neurosurgical patient before surgery. 903 cases were cerebral metastases and 69,5% aged over 50 years old. In 9,7% of cases we recorded a preoperative misdiagnosis of a metastasis due to few main reasons: unavailable information about a present primitive cancer, treacherous MRI image with a single confusing appearance of a cerebral lesion, age less than 50 years old, clinical presentation and biological evaluation inconsistent with malignancy. Authors point that these situations can have serious consequences related to professional competence, deterioration of the patient-doctor relationship, increasing costs for completion of diagnosis and treatment, and inadequate information about patient’s prognosis

A Quantitative Assessment of Tremor and Ataxia in Female FMR1

The fragile X-associated tremor/ataxia syndrome (FXTAS) is a relatively common cause of balance problems leading to gait disturbances in older males (40%) with the premutation. FXTAS is less common in females. We utilized the CATSYS system, a quantitative measure of movement, in 23 women with FXTAS (mean age 62.7; SD 12.3), 90 women with the premutation without FXTAS (mean age 52.9; SD 9.4), and 37 controls (mean age 56.53; SD 7.8). CATSYS distinguished differences between carriers with and without FXTAS in postural tremor, postural sway, hand coordination, and reaction time tasks. Differences were also seen between carriers without FXTAS and controls in finger tapping, reaction time, and one postural sway task. However, these differences did not persist after statistical correction for multiple comparisons. Notably, there were no differences across groups in intention tremor. This is likely due to the milder symptoms in females compared to males with FXTAS
