Plain films are not accurate in planning internal fixation in vancouver type B1 periprosthetic femoral fractures and in distinguishing between subtypes B1 And B2.

Background: While few studies analysed the diagnostic validity of preoperative radiographs in distinguishing between Vancouver type B1 and B2 periprosthetic femoral fractures (PFFs), no investigation has been conducted to assess the degree of diagnostic validity of preoperative radiographs in identifying the fracture course and planning the most appropriate treatment. We analysed the diagnostic validity of radiographs in detecting the fracture course and stem stability in Vancouver type B PFFs.

Methods: Vancouver type B PFFs with different fracture courses were randomly performed in 36 dried cadaveric femurs in which a femoral broach had previously been implanted.

Is postoperative hyponatremia a real threat for total hip and knee arthroplasty surgery?

Postoperative hyponatremia (POH) is thought to be a fearsome complication of orthopedic surgery. Primary aim of this cohort study was to evaluate the incidence of POH and its clinical relevance in elective surgery, outlining differences between total knee arthroplasty (TKA) and total hip arthroplasty, looking for the presence of any risk factor commonly related to POH.Four hundred two patients that underwent total hip arthroplasty and total knee arthroplasty performed between 2016 and 2017 were retrospectively examined.

Long-term follow-up of neuropsychological functions in patients with high grade gliomas: can cognitive status predict patient's outcome after surgery?

Background: Patients affected by a high-grade glioma (HGG) have a poor prognosis with a median survival of 12-16 months. Such poor prognosis affects the perception of the remaining life by patients and the neuropsychological status can strongly affect every-day functioning of these patients. Monitoring changes of neuropsychological functioning (NPF) overtime may provide better clinical information and optimize the neuro-oncological management.

A neuroanatomical account of mental time travelling in schizophrenia: A meta-analysis of functional and structural neuroimaging data.

Mental time travel (MTT) abilities could be particularly compromised in schizophrenic patients due to a deficit of the cognitive processes at the basis of remembering the past and imaging the future: constructive processes, theory of mind and self-awareness. Accordingly, we assumed that the neural circuits typically associated with MTT in healthy people might be partially compromised in chronic schizophrenic patients. To quantitatively and anatomically test our hypothesis, we run two meta-analyses using the Activation Likelihood Estimate method: (i) a neurofunctional meta-analysis on MTT in healthy subjects, (ii) a morphometrical meta-analysis on chronic schizophrenia.

[The effect of the administration of an amino acid solution containing acetate on the calcium balance in surgical patients].

A frequent trouble in total parenteral nutrition is the occurrence of a negative calcium balance, due to reduction of calcium tubular reabsorption in acidosis. This condition could depend on acid metabolites raise, coming from degradation of nutritional amino acid mixtures. Authors have evaluated the effect of acetates addition to amino acid solutions on calcium balance.

Chemotherapy and tumoral markers in ovarian carcinoma.

Variations in tumoral markers (CA 125, CEA, AFP) in women with primary epithelial invasive ovarian cancer, after surgical operation for hysterectomy and chemotherapeutic treatment have been studied. The Authors stress the importance of alpha-fetoprotein monitoring in these women in order to evaluate a cytotoxic effect of the drugs used for the chemiotherapy on liver tissue.
