Radiation damage to brain and cranial soft tissues: outcome and incidence before and after reduction in dose

Introduction. To date there is a lack of studies dedicated to the objectification of the palpation data obtained by a specialist during the osteopathic examination. The issue of the evidence of the results of osteopathic correction still remains important. Search for instrumental methods allowing to register and to measure various palpation phenomena and manifestations of somatic dysfunctions is very relevant for the development of osteopathy as a science. It is also very important to find objective characteristics of these methods.Goal of research — to study viscoelastic characteristics of the soft tissues of the lower legs by palpation and instrumental methods before and after osteopathic correction.Materials and methods. 22 volunteers (12 women and 10 men) aged 18–23 years without complaints of the musculoskeletal system were examined. Osteopathic diagnostics and measurement of the viscoelastic properties of muscles were carried out by the method of vibration viscoelastometry before and after osteopathic correction.Results. Correlation analysis by Spearman showed that the subjective assessment of an osteopath positively correlated with both elasticity (r=0,43, p<0,05) and viscosity of soft issues (r=0,29, p<0,05). For the gastrocnemius muscle, this pattern was even more pronounced — for elasticity r=0,51, p<0,05, for viscosity =0,34, p<0,05. After osteopathic correction no changes in the elasticity of the soft tissues were observed. The viscosity of the tissues reduced, but in the projection of the gastrocnemius muscle, these changes were not statistically significant (p=0,12), whereas in the projection of the soleus muscle statistically significant changes (p=0,034) were observed.Conclusion. Changes in the viscoelastic properties of tissues demonstrated that the effects of osteopathic correction with the use of myofascial mobilization techniques, articulation mobilization techniques, and lymphatic drainage techniques were not obvious. The elasticity of soft tissues of the lower legs did not change, while the viscosity decreased, especially in the projection of the soleus muscles. This effect of the osteopathic correction can be associated with the effect of thixotropy — the transformation of gel-like intercellular substance into sol. Thus, the research showed that vibration viscoelastometry can be used for the objectifi cation of the condition of soft tissues and of the effects of osteopathic correction.

Linear And Nonlinear

Walking performance is usually assessed by linear analysis of walking outcome measures. However, human movements consist of both linear and nonlinear complexity components. The purpose of this study was to use bidimensional multiscale entropy analysis of ultrasound images to evaluate the effects of various walking intensities on plantar soft tissues. Twelve participants were recruited to perform six walking protocols, consisting of three speeds (slow at 1.8 mph, moderate at 3.6 mph, and fast at 5.4 mph) for two durations (10 and 20 min). A B-mode ultrasound was used to assess plantar soft tissues before and after six walking protocols. Bidimensional multiscale entropy (MSE2D) and the Complexity Index (CI) were used to quantify the changes in irregularity of the ultrasound images of the plantar soft tissues. The results showed that the CI of ultrasound images after 20 min walking increased when compared to before walking (CI4: 0.39 vs. 0.35; CI5: 0.48 vs. 0.43, p < 0.05). When comparing 20 and 10 min walking protocols at 3.6 mph, the CI was higher after 20 min walking than after 10 min walking (CI4: 0.39 vs. 0.36, p < 0.05; and CI5: 0.48 vs. 0.44, p < 0.05). This is the first study to use bidimensional multiscale entropy analysis of ultrasound images to assess plantar soft tissues after various walking intensities.

Prospective Controlled Study

Abstract: Introduction: Airway management is an integral part of general anaesthesia, which may lead to severe short- and long-term complications. Aim: We assessed whether the application of a checklist for the steps of airway management reduces the number of complications in our institute. Method: In our observational, prospective, controlled study we made a checklist and a data collection sheet. Each airway management was performed for one month without the checklist and then for one month in the possession of the checklist. We evaluated the outcome of airway maneuvers and the occurrence of related early complications before and after the introduction of the checklist. The primary endpoint was the incidence of unexpected difficult airway. The secondary endpoints were difficult intubation, successful first intubation, aspiration, cardiac arrest, post-induction hypotension and desaturation, soft tissues/teeth injuries. Our results were also corrected for factors that affect the risk of complications (urgency of interventions, medical experience). Results: We did not find any difference in the frequency of acute complications before the introduction of the checklist (n = 439) and during the subsequent period (n = 423). At the primary endpoint (7.29% and 6.14%), there was no substantive difference (1.15%, 95% CI: –2.26%–4.56%, p = 0.5). No differences were found regarding the secondary and other endpoints. Following the correction of risk factors, there was no impact of the checklist on the incidence of complications. Conclusion: The introduction of the checklist in itself did not result in a significant change in the risk of short-term complications of airway management in our institution.

Background: The purpose of this study was to identify the optimal pin insertion point to minimize finger motion restriction for proximal phalangeal fixation in cadaver models. Methods: We used 16 fingers from three fresh-frozen cadavers (age, 82–86 years). Each finger was dissected at the level of the carpometacarpal joint and fixated to a custom-built range of motion (ROM)-measuring apparatus after skin removal. The pin was inserted into the bone through four gliding soft tissues: the interosseous hood, dorsal capsule, lateral band, and sagittal band. Then, each tendon was pulled by a prescribed weight in three finger positions (flexion, extension, and intrinsic plus position). Changes in the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) angles were measured before and after pinning. We compared the differences between the insertion points using the Tukey-Kramer post hoc test. Results: Placement of pins into the sagittal band significantly restricted MCP joint flexion, while placement into the dorsal capsule and lateral band significantly restricted PIP joint flexion. Only placement into the interosseous hood showed no significant difference in joint angles between the three finger positions compared to pre-pin insertion. There were no significant effects on MCP, PIP, and DIP joint extension. Conclusions: The ROM of the MCP joint was obstructed due to pinning in most areas of insertion. However, pin insertion to the interosseous hood did not obstruct the finger flexion ROM compared to that of other gliding soft tissues; therefore, we believe that the interosseous hood may be a suitable pin insertion point for proximal phalangeal fixation.

Purpose. We have observed worsening thumb pain following carpal tunnel release (CTR) in some patients. Our purpose was to determine the effect of open CTR on thumb carpometacarpal (CMC) biomechanics.Methods. Five fresh-frozen cadaver arms with intact soft tissues were used. Each specimen was secured to a jig which fixed the forearm at 45° supination, and the wrist at 20° dorsiflexion, with thumb pointing up. The thumb was axially loaded with a force of 130 N. We measured 3D translation and rotation of the trapezium, radius, and first metacarpal, before and after open CTR. Motion between radius and first metacarpal, radius and trapezium, and first metacarpal and trapezium during loading was calculated using rigid body mechanics. Overall stiffness of each specimen was determined.Results. Total construct stiffness following CTR was reduced in all specimens but not significantly. No significant changes were found in adduction, pronation, or dorsiflexion of the trapezium with respect to radius after open CTR. Motion between radius and first metacarpal, between radius and trapezium, or between first metacarpal and trapezium after open CTR was not decreased significantly.Conclusion. From this data, we cannot determine if releasing the transverse carpal ligament alters kinematics of the CMC joint.

As a rule, periodontal diseases are accompanied by marginal recession of the gums, loss of attachment and exposure of the roots of the teeth. Traditional drugs for injection treatment are being replaced by modern drugs based on high molecular weight hyaluronic acid, which are successfully and highly efficiently used for local therapy of inflammatory and destructive periodontal diseases. In order to restore the volume of soft tissues in the interdental spaces, eliminate recessions and bleeding of the gingival margin, a preparation of high molecular weight hyaluronic acid “Revident +” was used, which was injected into the base of the gingival papilla at a distance of 2—3 mm from its top with the bevel of the needle upwards. To assess gingival bleeding, the PBI (papilla bleeding index) index was used, which is a sensitive indicator of the severity of gingival inflammation. The magnitude of gingival recession before and after treatment was assessed according to its severity: mild — up to 3 mm, moderate — 3—5 mm, and severe — 6 and more mm. Examination of periodontal patients before and 1.5 months after the application of high molecular weight hyaluronic acid in the composition of the Revident + preparation showed that the degree of gingival bleeding according to PBI decreased significantly after the third visit from 4 to 2 and from 3 to 1, respectively. The degree of gingival recession in the area of the anterior group of teeth decreased by an average of 2.1 mm, in the area of premolars — by 2.5 mm, and in the area of molars — by 2.8 mm.

Orbital Blowout Fractures

Acute posttraumatic enophthalmos is a well-known symptom occurring in orbital blowout fractures. Its late onset in the absence of radiologic evidence of displaced fractures is rare and traditionally attributed to ischemic liponecrosis or fibrotic scarring of endo-orbital soft tissues. In this article, we describe a case of facial trauma, diagnosed and treated at the Maxillo-Facial Surgical Department of Hospital Ca’ Granda Niguarda of Milan, in which delayed monolateral enophthalmos is associated with CT evidence of remodeling of orbital walls attributed to atelectasis of the maxillary sinus, as occurs spontaneously in patients suffering from silent sinus syndrome (SSS). Despite that classic criteria exclude traumatic etiology of SSS, recent literature suggests the possibility to include it. Our case is the first reported in literature supported by complete clinical and radiological documentation obtained before and after the condition established itself. The analogy with cases of spontaneous obstacle of aeration allows us to choose “two-step” surgical treatment with endoscopic uncinectomy and antrostomy and a delayed surgical correction of orbital volume to improve aesthetic results. The case described in this article and the review of the literature may focus physicians’ attention on evaluating the possible traumatic changes in the physiologic sinus drainage system.

A set of sodium borosilicate glasses mixed with different modifier oxides, viz., Li2O, MgO, CaO and ZnO, doped with antimicrobial oxide viz. CuO were synthesized. The structural (FT-IR spectroscopy, SEM and XRD) and bioactivity studies of the glasses were carried out before and after 30 days of immersion in simulated body fluid (SBF) under static conditions. Optical absorption spectra of all the glasses exhibited a broad absorption band identified due to 2B1g→2B2g octahedral transition of Cu2+ ions. Glass microstructure is analyzed using SEM images and XRD patterns to authenticate glass bioactivity (viz. to confirm whether there is formation of hydroxyapatite (HAp) layer on the surface). For further confirmation of the formation of HAp on the surface of the post immerse samples, the FTIR spectra were recorded. The spectra revealed some vibrational peaks of calcium phosphate. Solubility (weight loss due to immersion in SBF) percentage is found to be different for different modifiers mixed glasses containing antibacterial CuO. SEM results confirm apparent nodular calcium phosphate microcrystalites. It is observed that the addition of antimicrobial oxide has a positive effect on the bioactivity of glass and make these glasses as fourth-generation biomaterials, which are being extensively used to heal the wounds in the human body by facilitating the growth of soft tissues.
