Analysis of Point Shear Wave Elastography and Biochemical Markers for the Detection of Liver Fibrosis.

Background and Objectives: This work focuses on the possibility of using the point shear wave elastography (pSWE) method for detecting biochemical markers in diffuse liver diseases. Additionally, this study addresses the issue of the influence of ultrasound factors on the pSWE quality indicators of the obtained measurements. Materials and Methods: A pSWE examination was performed on 139 patients (69 female and 70 male) diagnosed with diffuse liver disease. The average age for all patients was 50.7 ± 15.0 years (female: 52.7 ± 15.2 years; male: 48.8 ± 14.6 years). Of these 139 patients, 65 met the inclusion criteria regarding biochemical parameters. The pSWE quality indicators were related to abnormalities found in B-mode ultrasound. Results: A strong positive correlation was found between the results of the pSWE and all biochemical indexes analysed, with the exception of age/platelet count (PLT), for which an average correlation was obtained. The greatest correlation was observed between the elastography and King's Score index. There was no correlation observed between elastography and any of the analysed parameters or biochemical indexes considered. The pSWE measurements were impaired by factors such as thick soft tissue, uneven hepatic surface, hepatomegaly and female gender. No statistically significant difference in pSWE quality indicators parameters was found between disease entities. Conclusions: pSWE seems to be a complementary method for detecting biochemical indexes, but its results can be influenced by numerous factors.

Hand Injuries in the Polish Silesian Paediatric Population-An Exploratory Cross-Sectional Study of Post-Traumatic X-rays.

Background and objectives: In the paediatric population, hand injuries are one of the most frequent injuries and the second most frequent area of fracture. It is estimated that hand injuries account for up to 23% of the trauma-related causes of emergency department visits. Not only are they a significant factor in health care costs, but they may also lead to detrimental and long-term consequences for the patient. The discrepancy observed between the published studies suggests a geographical variation in their epidemiology. The aim of this study is to determine the localisation of injuries and fractures involving the hand in the paediatric population of the Polish Silesia region. This exploratory cross-sectional study involved 1441 post-traumatic hand X-ray examinations performed at the Department of Diagnostic Imaging of the John Paul II Upper Silesian Child Health Centre in Katowice between January and December 2014. Materials and Methods: The study group consisted of 656 girls and 785 boys who were 11.65 ± 3.50 and 11.51 ± 3.98 years old, respectively (range: 1-18 years). All examinations were evaluated for the location of the injury and presence of fracture(s). Results: Finger injuries were dominant (n = 1346), with the fifth finger being the most frequently injured (n = 381). The majority of injuries were observed among children who were 11 years old (n = 176), with a visible peak in the 11- to 13-year-old group. A total of 625 bone fractures were detected. Fractures of the proximal phalanges (n = 213) and middle phalanges (n = 159) were most common, and fifth finger (n = 189) predominance was again observed. A gender-independent positive correlation was found between patients' age and finger injuries (p < 0.01) as well as metacarpal injuries (p < 0.01). There was no correlation between patients' age and fractures in these locations (p > 0.05). Metacarpal injuries (p < 0.01), finger injuries (p < 0.01), fractures (p = 0.01), and fractures with displacement (p = 0.03) were more common among males regardless of age. Conclusions: The results indicate that 11-year-old boys are at an increased risk of hand injuries and fractures. The distal and middle phalanges of the right hand, especially of the fifth digit, were the most susceptible to fracture localisation. Thus, injuries in these areas should be perceived as most likely to cause fractures and therefore demand careful examination.

Endovascular treatment of small (< 5 mm) unruptured middle cerebral artery aneurysms.

PURPOSE: We report our experience with endovascular treatment of these lesions, with special consideration of angiographic and clinical outcomes and periprocedural complications. MATERIAL AND METHODS: The analysis included treatment results of 19 patients with 20 aneurysms. The aneurysm size ranged from 1.9 to 4.7 mm (mean 3.8, SD 0.7). Clinical examinations with the use of modified Rankin Score and angiographic outcomes were evaluated initially postembolisation and at a minimum follow-up of six months. RESULTS: Initial post-treatment complete and near-complete aneurysm occlusion was achieved in 19 (95%) cases and incomplete occlusion in one (5%) case. Imaging follow-up, performed in 17 (89.4%) patients, showed no change in the degree of occlusion in 16 (94.1%) patients and coil compaction in one (5.9%). There were no retreatment procedures. The procedure-related mortality rate was 5% (1/20) and was associated with intraprocedural aneurysm rupture. There was a case of a clinically silent coil prolapse into the parent artery. The clinical follow-up evaluation achieved in 17 (89.4%) patients showed no change in clinical status in all followed patients. CONCLUSIONS: Endovascular treatment of small unruptured middle cerebral artery aneurysms is feasible and effective. The procedure-related complications are not negligible, especially in terms of the benign natural course of these lesions.

Safety and efficacy of treatment of very small intracranial aneurysms.

PURPOSE: Very small intracranial aneurysms (VSIAs) may cause many neurological complications and even death. Thanks to technological progress and higher quality of non-invasive neuroimaging methods, these pathologies can be investigated sooner and treated earlier. Due to the controversy surrounding invasive treatment of these pathologies, the aim of the study was to analyse methods of treatment, their outcome, and complications in a group of patients with VSIAs. MATERIAL AND METHODS: Out of 444 cases of intracranial aneurysms treated in our centre, 65 aneurysms met the radiological criteria of VSIAs. The parameters - width and length of the aneurysm's neck and width, length, and height of the aneurysm's dome - were measured. The analysed parameters were as follows: symptoms upon admission and after treatment, days in hospital, and intraoperative complications. Clinical and radiological intensity of subarachnoid haemorrhage (SAH) was evaluated by using the Hunt-Hess and Fisher scales. The degree of embolisation of the aneurysm after the procedure was assessed using the Montreal Scale. Clinical outcome was assessed by Glasgow Outcome Scale. RESULTS: 50.77% of VSIAs were treated with endovascular procedures and 49.23% with neurosurgical clipping. SAH was presented in 38.46% of patients with VSIAs. Intraoperative complications were presented in 16.92% of patients with VSIAs, and the most common complication was ischaemic stroke. Stents were used in 51.52% of VSIAs. In 69.70% of embolisation procedures at VSIAs complete obliteration was achieved. The average result in the Montreal Scale was 1.31 (SD = 0.66). CONCLUSION: VSIAs can be treated as effectively and safely as larger aneurysms, by both endovascular and surgical methods.

The role of inflammation and potential pharmacological therapy in intracranial aneurysms.

Intracranial aneurysms remain important clinical concern. There is relatively low risk of rupture of symptomless aneurysms incidentally found in MRA or CTA performed due to other indications. Not all of the intracranial aneurysms should or can be treated with neurosurgery intervention or endovascular embolization. Clinical strategy for small, symptomless, unruptured aneurysms is still questionable. Mechanisms underlying aneurysms formation, progression and rupture are poorly understood. Inflammation is one of the factors suspected to participate in these processes. Therefore the aim of this manuscript is to present current state of knowledge about the role of inflammation in the formation and progression of intracranial aneurysms and in their rupture process. Current knowledge about possible pharmacological treatment of intracranial aneurysms will also be presented. Macrophages infiltration seems to participate in the formation of intracranial aneurysms. Inhibition of signals sent by macrophages may prevent the aneurysms formation. Inflammation present in the wall of the aneurysm seems to be also related to the aneurysm's rupture risk. However it does not seem to be the only cause of the degeneration, but it can be a possible target of drug therapy. Some preliminary studies in humans indicate the potential role of aspirin as a factor that decrease the level of inflammation and lower the risk of rupture of intracranial aneurysms. However further research including a greater number of subjects and a prospective randomized design are necessary to assess the role of aspirin in preventing strategy for small, symptomless, unruptured intracranial aneurysms.

Endovascular treatment of small cerebral arteriovenous malformations as a primary therapy.

PURPOSE: The patient population that would benefit most from endovascular curative treatment of intracranial arteriovenous malformations is not clearly established. The aim of the study was to determine the effect of curative embolization of cerebral arteriovenous malformations with special regard to radiographic and clinical outcomes and procedure-related complications. MATERIAL AND METHODS: Between January 2009 and December 2014, 18 patients with intracranial arteriovenous malformations were embolized with Onyx with intent to cure. There were 4 women and 14 men with a mean age of 40 years (range 10-62 years). Inclusion criteria were: maximal diameter of the lesions ≤ 3 cm and arterial supply consisting of no more than 2 major arteries. There were 5 (27.8 %) patients with ruptured and 13 (72.2%) with unruptured lesions. Mean arteriovenous malformations size was 2.3 cm (range 1.5-2.9 cm). RESULTS: Thirty-three procedures were performed in 18 patients. Total obliteration was achieved in 5 patients (27.8%). The most common reason for initial incomplete angiographic occlusion were unfavorable angioarchitectural features of arteriovenous malformations with the rate of 44.4%. The mean follow-up of patients with complete occlusion was 35.2 months (range 18-60 months). Complication rate was 12.1%. One patient had permanent neurological deficit with resulting morbidity of 5.6%. There were no deaths. CONCLUSIONS: Embolization of intracranial arteriovenous malformations plays a limited role as a sole therapeutic modality even in terms of small lesions with two or less arterial feeders, although larger prospective series are necessary to confirm your findings. Associated complications are not trivial and should be considered when choosing this form of treatment.

Cerebral arteriovenous malformations - usability of Spetzler-Martin and Spetzler-Ponce scales in qualification to endovascular embolisation and neurosurgical procedure.

PURPOSE: Arteriovenous malformations (AVMs) are connected with cerebral haemorrhage, seizures, increased intracranial pressure, headaches, mass effect, and ischaemia symptoms. Selection of the best treatment method or even deciding if intervention is required can be difficult. MATERIAL AND METHODS: The study included 50 patients who were diagnosed with cerebral AVMs and treated in our Centre between 2008 and 2014. A total of 111 procedures were performed, including 94 endovascular embolisations and 17 neurosurgical procedures. Medical records and imaging data were reviewed for all patients. All AVMs were measured and assessed, allowing classification in Spetzler-Martin and Spetzler-Ponce scales. RESULTS: Complete or partial treatment was observed in 88.24% of neurosurgical procedures and in 84.00% of embolisations. Early complication rate was 21.28% for embolisation and 17.65% for neurosurgical procedures, while Glasgow Outcome Scale was 4.89 (σ = 0.38) and 5.0 (σ = 0.00), respectively. According to the Spetzler-Martin scale, cerebral haemorrhages occurred more frequently in grade 1, but no statistical significance was observed. In Spetzler-Ponce class B lower grades in Glasgow Coma Scale (GCS) were noticed (p = 0.02). Lower GCS scores were also correlated with deep location of AVM and with eloquence of adjacent brain. Patients with Spetzler-Martin grade 1 were more frequently qualified for neurosurgical procedures than other patients. CONCLUSIONS: Treating AVMs requires coordination of a multidisciplinary team. Both endovascular embolisation and neurosurgical procedure should be considered as a part of multimodal, frequently multistage treatment. Spetzler-Martin and Spetzler-Ponce scales have an influence on haemorrhage frequency and patients' clinical condition and should be taken into consideration in selecting the treatment method.

Endovascular treatment of complex intracranial aneurysms.

PURPOSE: Complex intracranial aneurysms (CIA) are heterogenous group of intracranial vascular malformations. Due to its giant size, difficult location, broad neck, branches arising from the aneurysm, wall structure, calcification, presence of intraluminal thrombus or previous treatments it requires more careful approach. The aim of this study was to evaluate endovascular treatment results of CIA in our Department. MATERIAL AND METHODS: In order to differentiate CIA from all the aneurysms, treated endovascularly in years 2008-2014, authors proposed their own qualification criteria. Additionally, subgroup of patients with CIA with simultaneous subarachnoid haemorrhage (SAH) was divided. Clinical outcomes of patients were assessed with Glasgow Outcome Scale (GOS), while radiological outcomes were assessed with Montreal Scale. Aneurysm localization, incidence of aborted procedures, intraoperative complications were also evaluated. RESULTS: Internal carotid artery was the most common localization in both CIA and non-complex (nCIA) groups. Incidence of aborted procedures was significantly higher in CIA group than in nCIA (25% vs. 7%; p < 0.01). CIA group had worse Montreal scores then nCIA group (1.90 vs. 1.49; p < 0.01). Clinical outcome in GOS scale in patients with SAH and CIA was significantly worse than in SAH and nCIA (2.86 vs. 4.06; p = 0.04). CONCLUSIONS: To conclude, proposed criteria of CIA should be taken into consideration during diagnosis and qualification to invasive treatment. Classifying aneurysm as CIA is related to greater possibility of aborting endovascular procedure due to technical difficulties.

Progressive regression of intracranial arteriovenous malformations after Onyx embolization.

Progressive regression of cerebral arteriovenous malformations (AVMs) is a rare phenomenon that may occur spontaneously or after previous surgical or endovascular incomplete obliteration. We present two cases of AVMs occluded partially with Onyx followed by the unexpected cure of the lesions with the angiographic evidences as well as multiannual follow-up.

Evaluation of Endovascular Embolization of Cerebral Aneurysms by Hydrogel Coils.

BACKGROUND: Hydrogel coils were created to improve the chances of an effective endovascular treatment of cerebral aneurysms. Achieving a high packing density of coils in the lumen of aneurysms can decrease the risk of recurrence. The aim of the present study is to report our initial experience on the effectiveness and safety of endovascular treatment of intracranial aneurysms with the use hydrogel coils. MATERIAL/METHODS: Sixty patients (age: 28-72 years) (45 women, 15 men) were treated. In 18 patients (30%), subarachnoid hemorrhage was present. Digital subtraction angiography (DSA) of cerebral vessels with rotational scanning was performed. Image analysis was performed by the Philips Integris 3D RA device,which is a specialized workstation (Three-Dimensional Rotational Angiography). 3D reconstructions of cerebral arteries were created based on the data. Sixty-six cerebral aneurysms were embolized with hydrogel coils, which expand in contact with blood. reaching the maximum diameter in about 20 minutes. In 29 aneurysms (43.9%), the effect of the procedure was confirmed on a follow-up DSA after 8.0±4.1 months from the initial treatment. RESULTS: A complete embolization was performed in 55 aneurysms (83.3%), and partial embolization in 11 aneurysms (16.7%). In 6 aneurysms (9.1%), re-embolization was necessary and it resulted in a complete embolization of 5 aneurysms. On a follow-up DSA, complete embolization was present in 25 aneurysms (86.2%), and partial embolization in 4 aneurysms (13.8%), respectively. CONCLUSIONS: Endovascular embolization with hydrogel coils is an effective and safe treatment method for cerebral aneurysms, although it carries the risk of some complications.

Endovascular Approach to Glomus Jugulare Tumors.

BACKGROUND: Paragangliomas are benign neuroendocrine tumors derived from the glomus cells of the vegetative nervous system. Typically, they are located in the region of the jugular bulb and middle ear. The optimal management is controversial and can include surgical excision, stereotactic radiosurgery and embolization. CASE REPORT: We report the endovascular approach to three patients harboring glomus jugulare paragangliomas. In all cases incomplete occlusion of the lesions was achieved and recanalization in the follow-up period was revealed. Two patients presented no clinical improvement and the remaining one experienced a transient withdrawal of tinnitus. CONCLUSIONS: It is technically difficult to achieve complete obliteration of glomus jugulare tumors with the use of embolization and the subtotal occlusion poses a high risk of revascularization and is not beneficial in terms of alleviating clinical symptoms.

Stent-assisted embolization of wide-neck anterior communicating artery aneurysms: Review of consecutive 34 cases.

OBJECTIVE: We report our experience with stent-assisted coiling of anterior communicating artery aneurysms with special consideration of angiographic and clinical outcomes, retreatment rate and periprocedural complications. MATERIALS AND METHODS: The analysis included 34 consecutive ruptured and unruptured wide-neck aneurysms. The aneurysm size ranged from 2 to 18mm (mean 5.47). Clinical examinations with the use of modified Rankin Score and angiographic outcomes were evaluated initially post-embolization and at a minimum follow-up of 6 months. RESULTS: Initial post-treatment complete and near-complete aneurysm occlusion was achieved in 32 (94%) and 2 (6%) cases, respectively. Imaging follow-up, performed in 28 (82%) patients, showed no change in the degree of occlusion in 25 (89%) cases and coil compaction in 3 (11%) patients. Of these, one (3.6%) patient underwent a second coil embolization. The periprocedural severe complication rate was 2.9% (1/35) and was associated with prolonged attempt of retrieval of migrated coil resulting in anterior cerebral artery infarct with serious clinical consequences. In another 3 patients periprocedural adverse events without delayed clinical consequences were noticed. The clinical follow-up evaluation achieved in 33 (97%) patients showed no change in 30 (91%) cases, one patient (3%) with clinical improvement and two (6%) cases of neurological deterioration. CONCLUSIONS: The use of stent is feasible and effective for coil embolization of wide-necked anterior communicating artery aneurysms. Although periprocedural complications resulting in severe morbidity are rare, they should be noted, since in terms of thromboembolic events some of them presumably have a potential to be avoidable.

The use of mechanical thrombectomy in the treatment of basilar artery occlusion--case report.

Occlusion of the basilar artery (BAO) is a rare cause of stroke, making up approximately 1% of all cases. Ischemic stroke within the basilar artery is associated with serious complications and high mortality (75-91%). BAO may occur initially in the form of mild prodromal symptoms with neurological disorders, the consequences of which can lead to death. For these reasons, BAO requires rapid diagnosis and treatment. We report the case of a 26-year-old man who suffered basilar artery occlusion and was treated with endovascular therapy. The patient was disqualified from intra-venous thrombolysis and endovascular treatment due to exceeding the therapeutic time window. Despite this, due to the location of ischemia and age of the patient, it was decided to proceed with a mechanical thrombectomy (TM). Vessel patency was restored using the Solitaire FR stent. Treatment continued with antiplatelet therapy. Despite a significant overshoot of the time window the procedure was successful and complete recanalization was achieved. During hospitalization, significant neurological symptom reductions were observed. There is no accurate data on which method of treatment of ischemic stroke is best for BAO. Expectations about the effectiveness of endovascular techniques are high.

Endovascular treatment of acute ischemic stroke - own experience.

OBJECTIVE: Presentation of the own experience in the treatment of ischemic stroke using endovascular methods of simultaneous evaluation of their effectiveness and safety. MATERIALS AND METHODS: The retrospective study involved a group of 18 patients hospitalized in 2005-2012 who were treated with intraarterial thrombolysis and mechanical thrombectomy. Overall there were 24 procedures performed. The investigated group consisted of seven (38.89%) women and 11 (61.11%) men. The average age of the patients was 60 years (SD ± 17, median - 60 years). RESULTS: In 62.50% of cases (n=15) the effect of revascularization has been achieved and another 12.50% of cases (n=3) recanalization was achieved only partially. Only in 25% of procedures (n=6) failed to achieve recanalization of the artery (TICI ≤ 1). The highest percentage of recanalized arteries were obtained by following the procedure of thrombolysis targeted - 69.24% (TICI ≥ 2b). In the case of mechanical thrombectomy total patency (TICI ≥ 2b) was 54.55%. The average duration of treatment (operation) is 157 min. After 30 days successful result of the neurological status was achieved in 57.14% of patients (n=8). Full return to independent functioning as defined within 3 months after the surgery (mRS ≤ 2) reached 57.14% of patients (n=8). CONCLUSION: Studies suggest that endovascular techniques are effective and safe in the treatment of ischemic stroke. Greater efficiency is characterized by intraarterial thrombolysis. Patients who were treated endovascular improved significantly.

Anomalous origin of the coronary artery from the wrong coronary sinus evaluated with computed tomography: "high-risk" anatomy and its clinical relevance.

OBJECTIVE: The aim of the study was to assess coronary arteries arising from the wrong coronary sinus, including CT-evaluated high-risk anatomic features, clinical symptoms and cardiac events during follow-up. METHODS: A total of 7,115 patients scheduled for 64-slice or dual-source cardiac CT were screened for the presence of isolated anomalous origin of the coronary artery from the wrong coronary sinus. RESULTS: Anomalous origin of the coronary artery was found in 54 (0.76 %) patients (29 men, 25 women, mean age 60.9 ± 11.6 years). Sixteen (30 %) patients with abnormal right coronary origin (ARCA) more commonly had a slit-like orifice (15 vs. 3; p < 0.001), intramural course (15 vs. 3; p < 0.001) and interarterial course (11 vs. 0; p < 0.001) than 22 (41 %) and 13 (24 %) individuals with abnormal circumflex artery (ALCx) and left coronary artery (ALCA) origin, respectively. Patients with ALCA presented less frequently with chest pain than subjects with ARCA and ALCx (25 vs. 3; p = 0.03). Patients with ARCA tended to show higher occurrence of cardiac events in the follow-up than individuals with ALCA and ALCx (5 vs. 4; p = NS). CONCLUSIONS: High-risk anatomy features are most common in patients with ARCA and these patients also have higher prevalence of chest pain and cardiac events in the follow-up than individuals with ALCA and ALCx. KEY POINTS: • Multislice computed tomography enables detection and evaluation of the coronary artery anomalies. • Anomalous anatomy of the coronary artery potentially influences the prevalence of adverse events. • Adverse events tend to be most common in anomalous right coronary arteries.

Cephalic index in the first three years of life: study of children with normal brain development based on computed tomography.

Cephalic index is a highly useful method for planning surgical procedures, as well as assessing their effectiveness in correcting cranial deformations in children. There are relatively very few studies measuring cephalic index in healthy Caucasian young children. The aim of our study was to develop a classification of current cephalic index for healthy Caucasian children up to 3 years of age with normal brain development, using axial slice computer tomography performed with very thin slices (0.5 mm) resulting in more accurate measurements. 180 healthy infants (83 females and 97 males) were divided into 5 age categories: 0-3, 4-6, 7-12, 13-24, and 25-36 months. The average value of cephalic index in children up to 3 years of age amounted to 81.45 ± 7.06. The index value in case of children under 3 months was 80.19, 4 to 6 months was 81.45, 7 to 12 months was 83.15, in children under 2 years was 81.05, and in children under 3 years was 79.76. Mesocephaly is the dominating skull shape in children. In this study, we formulated a classification of current cephalic indices of children with normal brain development. Our date appears to be of utmost importance in anthropology, anatomy forensic medicine, and genetics.

Intervertebral disc calcification in children: Case description and review of relevant literature.

BACKGROUND: Intervertebral disc calcification is a rare condition in children; in most cases, it is asymptomatic and therefore not diagnosed. CASE REPORTS: In our study, we present a case of idiopathic intervertebral disc calcification within the cervical segment, at the level of C2/C3 and C4/C5 vertebrae in a 5-year-old girl with torticollis. Basic neurological examination supplemented by X-ray examination was performed, showing calcification within the cervical segment at the level of C2/C3 and C4/C5 vertebrae. CONCLUSIONS: In order to complement the diagnostics, a CT scan of the cervical spine was performed; the scan confirmed the diagnosis and revealed additional calcification of the anterior longitudinal ligament at the level of C4/C5 vertebrae.

Reliability of inter-recti distance measurement on ultrasound images captured by novice examiners.

BACKGROUND: With the increased interest in inter-recti distance measurement using ultrasound imaging in physiotherapy, there is a question of measurement reliability, and the importance of the examiner's experience. PURPOSE: The study aimed to investigate the reliability of inter-recti distance measurement in a DICOM viewer software by an experienced radiologist. For the measurement, the radiologist used linea alba images captured by two physiotherapists who were novice examiners. METHODS: Ultrasound images were acquired by two novice examiners on repeated occasions 7 days apart (sessions A and B) in 28 nulliparous women at supraumbilical, umbilical, and infraumbilical locations along linea alba. RESULTS: Excellent intra-examiner reliability of inter-recti distance measurements was shown at the supraumbilical and umbilical levels (ICC2,k = 0.941-0.983) with minimal detectable change (MDC95) ranging from 1.31 mm to 2.29 mm. Infraumbilical measurements had good to excellent reliability (ICC2,k = 0.894-0.972) with MDC95 ranging from 0.33 mm to 0.72 mm. Session A inter-examiner reliability was excellent for the mean measurements of two, three, four, and five images taken at each location (ICC2,k = 0.913-0.954) with MDC95 ranging from 0.47 mm to 2.96 mm. Session B inter-examiner reliability was excellent for the mean measurements of two, three, four, and five images taken at the supraumbilical and umbilical (ICC2,k = 0.94-0.98), MDC95 ranging from 1.38 mm to 2.58 mm and good (ICC2,k ≥ 0.81) with MDC95 ranging from 0.72 mm to 0.80 mm at the infraumbilical locations. CONCLUSION: Novice examiners were able to capture good-quality ultrasound images of the linea alba that allowed for good to excellent intra- and inter-examiner reliability.

Technical aspects of inter-recti distance measurement with ultrasonographic imaging for physiotherapy purposes: the scoping review.

BACKGROUND: Inter-recti distance (IRD) measurement using musculoskeletal USI has been used in physiotherapy research, in particular, to investigate pregnancy-related diastasis recti abdominis (DRA) and to seek its effective treatment methods. Severe and untreated diastasis may result in the formation of umbilical or epigastric hernias. OBJECTIVE: This study aimed to systematically map physiotherapy-related research articles that included descriptions of IRD measurement procedures using USI to present their similarities and differences, and formulate recommendations on the procedure. DESIGN: A scoping review was conducted according to PRISMA-ScR guidelines, including 49 of 511 publications from three major databases. Publications were selected and screened by two independent reviewers whose decisions were consulted with a third reviewer. The main synthesized data items were: the examinees' body position, breathing phase, measurement sites, and DRA screening methods. The final conclusions and recommendations were the result of a consensus between seven reviewers from four research centers. RESULTS: Studies used 1-5 measurement sites that were differently determined. IRD was measured at the umbilicus (n = 3), at its superior (n = 16) and/or inferior border (n = 9), and at different levels: between 2 and 12 cm above the umbilicus, or a third of the distance and halfway between the umbilicus and xiphoid (n = 37); between 2 and 4.5 cm below the umbilicus or halfway between the umbilicus and pubis (n = 27). Different approaches were used to screen subjects for DRA. CONCLUSIONS: The discrepancies between the measurement procedures prevent between-study comparisons. The DRA screening method should be standardized. IRD measurement protocol standardization has been proposed. CRITICAL RELEVANCE STATEMENT: This scoping review indicates that the inter-recti distance measurement procedures using ultrasound imaging differ between studies, preventing between-study comparisons. Based on the results synthesis, the measurement protocol standardization has been proposed. KEY POINTS: The inter-recti distance measurement procedures using USI differ between studies. Proposed standardization concerns body position, breathing phase, measurements number per location. Determination of measurement locations considering individual linea alba length is suggested. Recommended locations: umbilical top, ½ of umbilical top-xiphoid, » of umbilical top-xiphoid/pubis distances. Diastasis recti abdominis diagnostic criteria are needed for proposed measurement locations.

Analysis of Serum Markers of Perioperative Brain Injury and Inflammation Associated with Endovascular Treatment of Intracranial Aneurysms: A Preliminary Study.

Embolization is the preferred method for treating intracranial aneurysms due to its less invasive nature. However, recent findings suggest that even uncomplicated embolization may cause structural damage to the brain through ischemic or inflammatory mechanisms. This study aimed to find possible biomarkers of brain injury and inflammation in patients suffering from intracranial aneurysms who underwent endovascular treatment by measuring serological markers indicating brain damage. The study involved 26 patients who underwent uncomplicated intravascular stenting for unruptured intracranial aneurysms between January 2020 and December 2021. Blood samples were collected before the procedure, at 6-12 h, and at 24 h after the procedure. The following protein biomarkers levels were tested with ELISA: S100B, hNSE, TNF, hsCRP, FABP7, NFL, and GP39. Statistical analysis of the results revealed significant increases in serum levels for the four biomarkers: FABP7-before 0.25 (ng/mL) vs. 6-12 h 0.26 (p = 0.012) and vs. 24 h 0.27 (p < 0.001); GP39-before 0.03 (pg/mL) vs. 6-12 h 0.64 (p = 0.011) and vs. 24 h 0.57 (p = 0.001); hsCRP-before 1.65 (µg/mL) vs. 24 h 4.17 (p = 0.037); NFL-before 0.01 (pg/mL) vs. 6-12 h 3.99 (p = 0.004) and vs. 24 h 1.86 (p = 0.033). These biomarkers are recognized as potential indicators of neurovascular damage and should be monitored in clinical settings. Consequently, serum levels of NFL, GP39, hsCRP, and FABP7 measured before and 24 h after endovascular procedures can serve as important markers for assessing brain damage and indicate avenues for further research on biomarkers of neurovascular injury.
