The diagnostic value of cerebrospinal fluids procalcitonin and lactate for the differential diagnosis of post-neurosurgical bacterial meningitis and aseptic meningitis

Tremor is the most common type of movement disorders. In practice this differential diagnosis of hyperkinesis is diagnosed clinically and the use of additional methods of objective assessment of tremor increases the accuracy of diagnosis. The use of paraclinical methods of objective assessment of tremor improves the accuracy of diagnosis. Comparison of the neurophysiological parameters of tremor with clinical characteristics has a high diagnostic value, which justifies its use in the routine practice of neurologists. The purpose of the review is to analysis basic electrophysiological characteristics of pathological tremor, as well as the presentation of the material of its own observation.

Abstract Background There is a lack of studies comparing PCT, CRP and WBC levels in the differential diagnosis of acute bacterial, viral, and mycoplasmal respiratory tract infections. It is necessary to explore the correlation between above markers and different types of ARTI. Methods 108 children with confirmed bacterial infection were regarded as group A, 116 children with virus infection were regarded as group B, and 122 children with mycoplasmal infection were regarded as group C. The levels of PCT, CRP and WBC of the three groups were detected and compared. Results The levels of PCT, CRP and WBC in group A were significantly higher than those in groups B and C (p < 0.05). The positive rate of combined detection of PCT, CRP and WBC was significant higher than that of single detection. There was no significant difference in PCT, CRP and WBC levels between the group of G+ bacterial infection and G− bacterial infection (p > 0.05). ROC curve results showed that the AUC of PCT, CRP and WBC for the diagnosis of bacterial respiratory infections were 0.65, 0.55, and 0.58, respectively. Conclusions PCT, CRP and WBC can be combined as effective indicators for the identification of acute bacterial or no-bacterial infections in children. The levels of PCT and CRP have higher differential diagnostic value than that of WBC in infection, and the combined examination of the three is more valuable in clinic.

Magnetic Resonance Imaging Mri

Ameloblastoma is an odontogenic tumor that shares clinical and imaging characteristics with other lesions of the jaws, such as odontogenic keratocyst, which makes the diagnosis difficult. However, in addition to radiographic and tomographic examinations, Magnetic Resonance Imaging (MRI) has been increasingly used, contributing with relevant additional information about the differentiation between solid and liquid components of the lesion. This case report was conducted to present two variations of ameloblastoma and discuss the radiographic, tomographic and MRI contribution in the differential diagnosis between ameloblastoma and odontogenic keratocyst.The signal intensity in T1-weighted MRI revealed internal fluid content in both cases, which was important in the differential diagnosis with other intraosseous lesions such as odontogenic keratocysts. This is probably due to the presence of keratin that increases the viscosity of the content and also for an intermediate signal intensity signal in T2-weighted MRI. Therefore, MRI revealed important internal characteristics of the reported lesions, which was very useful in the establishment of the differential diagnosis with other lesions.

Appendicitis Score

Acute nonspecific abdominal pain in children is the most common problem requiring differential diagnosis with acute appendicitis. Scales for integrated assessment of individual symptoms and their combinations have been proposed and are constantly being developed that allow predicting the likelihood of acute appendicitis. Purpose to assess diagnostic value of Pediatric Appendicitis Score (PAS) in groups of children in different ages. Materials and methods. 374 children aged 4 to 15 years with acute abdominal pain were evaluated in prospective randomized blinded study. Statistical analysis: ROC – curves, specificity and sensitivity, positive and negative predictive values; Kullback criteria; logistic regression analysis; discriminant analysis. Results. Detection frequency and diagnostic significance of the PAS scale predictors as well as obtained results by using the Pediatric Appendicitis Score depend on children age significantly. In terms of diagnosis of acute appendicitis, the PAS scale shows the best results in older children. Conclusions. Results of Pediatric Appendicitis Score depend on children ages due to different diagnostic value of predictors used in the PAS scale. Pediatric surgeons should keep in your mind these data. Modification of the scale is required taking into account the patient’s age. Further analysis of the issue of PAS using is needed. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. The authors declare no conflicts of interests. Key words: acute appendicitis, children, diagnosis, PAS scale.
