The work is devoted to the author´s method of investigation of tactile sensitivity, within its stereognostic sense, implemented by means of the original three-dimensional figures. It describes the types and forms of figures, especially, the study of the process of multi-component sensory tactile sensitivity. The author gives are examples of the evaluation and interpretation of the results, comparison with clinical data and instrumental methods of research. Testing is conducted on 470 practically healthy subjects and 232 patients with physical, psycho-neurological, psychiatric pathology by means of electrophysiological studies (electroneuromyography, evoked potentials, rheoencephalography, rheovasography), neuroimaging (magnetic resonance imaging).The proposed method of the study can be used for various types of medical examination (medical, military-medical, medical and social). It allows to carry out a differential - tentative diagnosis of several diseases (damage to the central and peripheral nervous systems, post-traumatic, vertebrogenic, endocrine, vascular, psychosomatic, psychiatric genesis of occupational diseases). The advantages of the technique are the adequacy assessment of the dynamics of the disease during treatment and (or) rehabilitation applicability in ambulatory - polyclinic con-ditions. The method can be used for the purpose of professional selection and vocational guidance, including in professions that demand a great deal of difficult-coordinated fine manipulative actions, an important component of which is tactile sensory afferentation (watch plants, jewelry businesses).

Abstract Background This study examined cervical transforaminal ligament(TFL) displays in cadavers and living bodies using magnetic resonance imaging (MRI) and evaluated the correlation between nerve entrapment in the brachial plexus by the TFL and cervical radiculopathy(CR). Methods First, 6 normal intact adult cervical specimens were used to calculate the relevant capacity in displaying the cervical TFLs by the three-dimensional fast imaging employing steady-state acquisition (3D-FIESTA). Second, 10 patients with CR and 10 healthy subjects were selected to perform the 3D-FIESTA sequence scan at the C4-T1 intervertebral foramina. The TFL display rate was calculated, and its correlation with CR was analysed. Results The microscopic anatomical results showed that the cervical TFL incidence was 39.6%. The relative capacity of the 3D-FIESTA sequence in displaying cervical TFLs showed a 96.6% specificity and a 73.7% sensitivity. In the 10 patients with CR, cervical TFLs were present in 17 intervertebral foramina, of which, 10 cases showed hypertrophy of the TFLs causing nerve entrapment, and corresponding symptoms of CR were found in 8 cases of cervical TFLs. The correlation between nerve root entrapment by the cervical TFL and CR showed a 96.8% specificity and an 80% sensitivity. In the 10 healthy subjects, cervical TFLs were present in 13 intervertebral foramina. Conclusions The MR 3D-FIESTA sequence has high clinical value in displaying cervical TFLs in both cadavers and living bodies. If 3D-FIESTA sequencing shows nerve entrapment by the TFL, the possibility of CR caused by this TFL is approximately 80.0%. Conversely, the possibility of CR remains at 3.2%.

Background: Cutis Verticis Gyrata (CVG) is a rare skin disease caused by overgrowth of the scalp, presenting as cerebriform folds and wrinkles. CVG can be classified into two forms: primary (essential and non-essential) and secondary. The primary non-essential form is often associated with neurological and ophthalmological abnormalities, while the primary essential form occurs without associated comorbidities. Discussion: We report on a rare case of primary essential CVG with a 4-year history of normal-colored scalp skin mass in the parietal-occipital region without symptom in a 34-year-old male patient, retrospectively summarizing his pathological and Computer Tomography (CT) and magnetic resonance imaging (MRI) findings. The major clinical observations on the CT and MR sectional images include a thickened dermis and excessive growth of the scalp, forming the characteristic scalp folds. With the help of CT and MRI Three-dimensional (3D) reconstruction techniques, the characteristic skin changes could be displayed intuitively, providing more evidence for a diagnosis of CVG. At the 5-year followup, there were no obvious changes in the lesion. Conclusion: Based on our observations, we propose that not all patients with primary essential CVG need surgical intervention, and continuous clinical observation should be an appropriate therapy for those in stable condition.

Purpose: The aim of this study was to assess the volumetry of the hippocampus in the Leber’s hereditary optic neuropathy (LHON) of blind patients. Methods: A total of 25 patients with LHON were randomly included into the study from the national health database. A total of 15 patients were selected according to the inclusion criteria. The submillimeter segmentation of the hippocampus was based on three-dimensional spoiled gradient recalled acquisition in steady state (3D-SPGR) BRAVO 7T magnetic resonance imaging (MRI) protocol. Results: Statistical analysis revealed that compared to healthy controls (HC), LHON subjects had multiple significant differences only in the right hippocampus, including a significantly higher volume of hippocampal tail (p = 0.009), subiculum body (p = 0.018), CA1 body (p = 0.002), hippocampal fissure (p = 0.046), molecular layer hippocampus (HP) body (p = 0.014), CA3 body (p = 0.006), Granule Cell (GC) and Molecular Layer (ML) of the Dentate Gyrus (DG)–GC ML DG body (p = 0.003), CA4 body (p = 0.001), whole hippocampal body (p = 0.018), and the whole hippocampus volume (p = 0.023). Discussion: The ultra-high-field magnetic resonance imaging allowed hippocampus quality visualization and analysis, serving as a powerful in vivo diagnostic tool in the diagnostic process and LHON disease course assessment. The study confirmed previous reports regarding volumetry of hippocampus in blind individuals.
