Authors: Tabesh M , Sh M Etemadi , Etemadi M , Naddaf F , Heidari F , Alizargar J
Published: September 2022

Background:

The oral cavity is colonized by a myriad of microorganisms, some of which are proven to be detrimental to human health. There have been numerous efforts to control the population of pathogenic agents in the oral cavity, including the usage of natural phytochemicals obtained from medicinal plants. Nasturtium officinale has long been used in traditional medicine for the management of hypertension, respiratory infections, and hyperglycemia, and its effectiveness against some microbes has been reported.

Aims:

To evaluate antimicrobial properties of a hydro-alcoholic extract of N. officinale against common oral pathogens namely Streptococcus mutans, Staphylococcus aureus, Lactobacillus acidophilus, Enterococcus faecalis, and Pseudomonas aeruginosa. Experimental laboratory study. Different dilutions of N. officinale hydro-alcoholic extract were the test solutions, the positive control was a bacterial suspension in sterile phosphate-buffered saline, whereas the negative control was the herbal extract only, without any bacterial inoculation. Hydro-alcoholic extract of N. officinale prepared in five different concentrations (105, 52.5, 26.25, 13.12, 6.56 mg.mL-1) was tested separately against Streptococcus mutans, Lactobacillus acidophilus, Pseudomonas aeruginosa, Enterococcus faecalis, and Staphylococcus aureus in a test of microdilution assay. Spectrophotometry was used to assess bacterial growth after 24 and 48 h.

Materials and Methods:

The data of optical absorbance reads from spectrophotometry were analyzed using repeated-measures analysis followed by Least Significant Differences (LSD) post hoc.

Results:

The highest growth inhibitory effect against S. mutans, E. faecalis, and S. aureus was observed at a concentration of 13.12 mg.mL-1; for L. acidophilus and P. aeruginosa, the most significant inhibition was observed at a concentration of 105 mg.mL-1.

Conclusion:

N. officinale extract effectively inhibited the growth of the tested oral bacteria at different concentrations but was more effective against S. mutans, E. faecalis, and S. aureus and so may be effective in managing some oral microbial infections.

Authors: Zhao Y , Wang L , Bao Y , Xu R , He S
Published: September 2022

Aim and Background:

This study aims to improve the geometric design of the distal cementless femoral prosthesis stem, thereby changing the stress distribution of the femoral prosthesis and reducing the proximal stress shielding and distal stress concentration of the femur, so as to obtain better bone growth and long-term stability.

Materials and Methods:

Two geometric shapes of the femoral stems, namely, inverted hollow cone and cross-shaped bottom groove, are designed for the distal femoral prosthesis. The model is built based on the femoral computed tomography (CT) data of healthy volunteers, and the finite element method is used to analyze and calculate the stress distribution of the two femoral prosthesis stems.

Results:

According to the length and width of bottom “cross” groove, the stress values of the femoral region of the cross-grooved distal femur are divided into five groups, namely, group 1 (length 1:1, groove width 1.0 mm); group 2 (length 1:1, groove width 1.5 mm); group 3 (length 1:1, groove width 2.0 mm); group 4 (length 1:2, groove width 1.0 mm); group 5 (length 1:2, groove 1.5 mm wide). And the non-grooved group of the distal femur is designated as group 0. In the segment A, B, and C of the femoral region, the difference in the mean stress between group 0 and groups 1, 2, and 3 have statistical significance.

Conclusion:

The bottom “cross” groove of the distal femoral prosthesis can change the stress distribution in the prosthesis-distal femoral region and reduce the stress concentration at the distal prosthesis. Wherein, the grooved design of length ratio 1:1 is more advantageous.

Authors: Altintaş E , Rençber A
Published: September 2022

Background to Aim:

To compare the effects of disinfectants on surface roughness of the conventional impression materials following chemical disinfection procedures.

Materials and Methods:

Equal numbers (65 for each impression material) of disc-shaped (15 × 3 mm) samples (Total n = 195) were fabricated from polyvinyl siloxane (Zhermack Elite), polyether (3M Impregum Penta Soft), and vinyl siloxane ether (Kettenbach Identium Lightbody) impression materials. Each impression material group was divided into five subgroups including one control group (n = 13). Impression material samples were immersed in CaviCide for 3 min, Zeta 7 solution for 10 min, and 5.25% sodium hypochlorite solution for 3 and 10 min. Surface roughness (Ra) was measured using a profilometer (Mitutoyo-SJ 410, Mitutoyo Corp.). The study data were analyzed statistically.

Results:

A statistically significant difference was found among impression materials and disinfectants in terms of surface roughness (P < 0.05). Polyvinyl siloxane material showed a lower Ra value compared to Polyether and VSE materials; while polyether material showed a significantly lower Ra value compared to VSE material. Ra values of the control group were significantly lower than the disinfectant group immersed in 5.25% NaOCl solution for 10 min.

Conclusion:

Among all impression materials, polyvinyl siloxane showed the least surface roughness following disinfection procedures. Impression disinfectants that are specially designed for disinfecting dental impressions resulted in less surface roughness in all impression materials. With this study, it was aimed to obtain a smooth and clear model for the production of correct and compatible prostheses in the laboratory while at the same time purifying the impressions from microorganisms.

Authors: Kaptı HB , Şahin AK , Özdemir Ö
Published: September 2022

Background:

One of the most important complications of diabetes mellitus (DM) is vision loss due to diabetic retinopathy (DR). Optical coherence tomography (OCT) provides visualization of early structural abnormalities of the retina and choroid.

Aim:

To compare retinal thickness (RT) and choroidal thickness (CT) between patients with DM without DR and healthy controls.

Patients and Methods:

Diabetic patients without DR were divided into two groups according to serum glycosylated hemoglobin (HbA1c) levels. Group 1: HbA1c ≤7.5 (n = 25) and group 2: HbA1c >7.5 (n = 23). The 3rd group was the healthy control group (n = 25). CT and RT measured by OCT were compared between the three groups.

Results:

CT in the subfoveal, temporal, and nasal quadrants was significantly higher in the healthy control group than in groups 1 and 2. Subfoveal and temporal quadrant CT in group 2 were significantly thinner than those in group 1. The average RT (ART) was thinner in group 1 than in the other groups, but there was no difference between the control group and group 2.

Conclusions:

This study showed that CT and ART decreased in diabetic patients without DR.

Published: September 2022

Extraskeletal Ewing's sarcoma (EES) is a rare soft tissue tumor predominantly observed in adolescents and young adults, and is characterized by aggressive behavior. So far, only two cases of primary axillary soft tissue EES have been reported in the literature. One of them was a 29-year-old female patient who presented with a lump in her left axilla. Upon examination, an irregular, painless mass, measuring 5 cm × 5 cm × 3 cm, was noted in the left axilla. A histopathological examination of the mass revealed small, round, blue cells with scant cytoplasm, round nuclei, numerous mitosis, and necrosis. An immunohistochemistry (IHC) examination was positive for CD99 and negative for ER, PR, Her2neu, CK7, CK5/6, CD56, CD45, CK-pan, CKHMW, P63, desmin, S100, TdT, vimentin, myogenin, synaptophysin, and chromogranin A. The patient was diagnosed with primary axillary soft tissue EES and was started on neoadjuvant chemotherapy. Twelve months later, she is clinically free from the disease.

Published: September 2022

Traumatic anterior hip dislocation is quite rare and accounts for 7% to 15% of all hip dislocations. Approximately 70% of anterior hip dislocations are the obturator type and represent less than 7% of all hip dislocations. Indentation fracture of the femoral head complicates 35–55% of obturator dislocations. Features of osteonecrosis of the femoral head and osteoarthritis of the hip joint may manifest within 2 years. Our index patient is a 19-year-old female who had conservative treatment for right obturator dislocation with indentation fracture of the femoral head. She recovered fully and had no features of osteonecrosis or secondary arthritis at 2 years postinjury. The aim of this report is to highlight the role of conservative treatment in the management of obturator dislocation with indentation fracture of femoral head.

Authors: Eze JN , Odimegwu CL , Okafor OC , Nwafia IN
Published: September 2022

Nodular vasculitis is a rare inflammatory disease of the skin and subcutaneous fat tissue, characterized by crops of small, tender, erythematous nodules on the legs, mostly on the calves and shins. We present a 17-year-old adolescent female who presented with a six-month history of cough; recurrent fever and bilateral lower limb multiple ulcerated nodules of 1-month duration. Clinical examination revealed generalized lymphadenopathy with bilateral pitting leg edema which had multiple nodules and discoid ulcers extending from the groin to the ankles and discharging purulent fluid. Tests for human immunodeficiency virus and tuberculosis were negative. Histology of nodule biopsy revealed extensive caseous and coagulative fat necrosis, granulomatous inflammation with epitheloid macrophages and multinucleated giant cells surrounding the necrosis, and lymphoid infiltration of vessel walls with fibrous thickening of the intima, typical of Whitfield-type erythema induratum. There was initial but very transient response to antibiotic treatment, with further deterioration and eventual death from overwhelming sepsis.

Published: September 2022

Background:

Morgagni hernia (MH) is a rare congenital defect of the diaphragm. Although the various surgical method has been proposed, there is no surgical consensus.

Aim:

In this study, we aimed to report the outcome of the patients that underwent surgery which is completed using a single port laparoscopic-assisted transabdominal closure of MH.

Patients and Methods:

This is a retrospective analysis of 18 pediatric patients who underwent novel laparoscopic MH repair at a single tertiary pediatric hospital between March 2018 and December 2020.

Results:

Of the 18 patients, 72% (n = 13) were male and 28% (n = 5) were female. The symptoms at admission included repeated chest infection (39%), dyspnea (33%), vomiting (17%), and abdominal pain (22%). The colon (78%) was the most frequently herniated organ. Hernias were bilateral, on the left, and on the right in seven, four, and seven cases, respectively. All surgical interventions were completed within 25–50 min. All patients started enteral feeding within 24 hours. All patients were discharged within 1–3 days without any complications. The mean follow-up period was 27 months.

Conclusions:

In conclusion, our method is characterized by a shorter operation time, early return to feeding, early discharge, excellent cosmetic results, low cost, and low recurrence rate. Further prospective trials are needed to compare our novel scarless technique to other methods.
Differences in SUV39H1 and Androgen Receptor Distribution in Adenomyomatous Hyperplasia and Prostatic Adenocarcinoma
Authors: Çelik M Akçay , Erdem H , Çankaya S , Arıcı Y Kaşko
Published: September 2022

Background:

Androgen receptor (AR) contributes to the growth of both early- and late-stage prostate cancer. Overexpression of suppressor of variegation 3-9 homolog 1 (SUV39H1) increases migration of prostate cancer cells, while depletion of SUV39H1 suppresses migration of prostate cancer cells.

Aim:

In this study, the aim was to show the relationships of AR and SUV39H1 with adenomyomatous hyperplasia (AH) and prostate adenocarcinoma (PCa).

Materials and Methods:

70 AH and 70 PCa preparations in Pathology Department from 2013 to 16 were retrospectively investigated. Samples with immunohistochemical staining for AR and SUV39H1 were evaluated with a light microscope. After pathologic investigation of samples, AR and SUV39H1 expressions were scored. The changes in the frequencies of the obtained scores in the AH and PCa groups were analyzed statistically.

Results:

AR expression was observed to be greater in AH compared to PCa. This difference was found to be statistically significant (p = 0.003). SUV39H1 expression was identified to be greater in PCa compared to AH and this showed statistical significance (p = 0.031). PCa samples were identified to have nearly 1.5 times more SUV39H1 mild staining compared to AH samples and this increase was two times for SUV39H1 strong staining.

Conclusion:

In our study, AR expression was greater in AH compared to PCa samples. This situation is inverse to the known mechanism and cannot be clearly explained. It needs to be supported with large series and other prognostic parameters. This study observed increased SUV39H1 values in PCa compared to AH and from this aspect, it may be considered an important poor prognosis parameter.

Published: September 2022

Introduction:

Pterygium represents a significant cause of visual impairment and blindness in the Amazon and surgery is the only definitive treatment available. The cost of surgery and the need for prolonged postoperative follow-up have proved to be an obstacle to its management. The aim of this prospective study carried out in the southern region of the Amazon was to evaluate telemedicine in the pterygium surgery follow-up to help make pterygium surgery postoperative care feasible in places without ophthalmologic assistance.

Materials and Methods:

Postoperative follow-up care was done through teleconsultation. It involved capturing photographs from the corneal and conjunctiva by trained technicians and sending them to a reading center for an ophthalmologist's assessment based on an asynchronous (store-and-forward) model. Patients and ophthalmologists were inquired about their satisfaction regarding the postoperative follow-up.

Results:

All pictures were classified as adequate, allowing proper assessments of results and complications. It was possible to manage the postoperative and conclude there were no postoperative surgical complications during the 6-month follow-up. All patients reported satisfaction with the remote performed evaluation and considered that all their doubts and expectations were met.

Conclusion:

Teleophthalmology allows remote access and can significantly improve eye care quality, access, and affordability. It may represent an alternative to providing pterygium surgery postoperative monitoring in areas without the availability of an ophthalmologist, making it possible to combat one of the leading causes of reversible blindness in the equatorial region.

Authors: González Katia Márquez , Quetzal Herrera Joel Isai
Published: September 2022

Objective:

The objective of this study is to report a case of superior orbital fissure syndrome (SOFS), secondary to ocular herpes zoster, with a favorable evolution.

Materials and Methods:

Herpes zoster ophthalmicus (HZO) usually presents with ocular manifestations, being infrequent with the ophthalmoplegia. SOFS secondary to HZO is rare. We present the case of a 72-year-old man with dermatome involvement of the first left trigeminal branch, secondary to herpes zoster infection, who also developed herpetic keratitis in the left eye. After 8 days of antiviral treatment, he developed total left eye ophthalmoplegia that required steroid treatment. The evolution of the ophthalmoplegia was favorable with resolution at 3 months of follow-up.

Conclusions:

It is essential to make known one of the complications of HZO infection, although not as frequent, just as important, is to recognize this pathology when it occurs for prompt management and recovery.

Klippel–Trenauny syndrome is a rare neurocutaneous syndrome characterized by vascular malformations and deformed growth of bone and soft tissue. Vascular malformations can result in dilated lymphatics and blood vessels. The major complications seen in these parturients during pregnancy and the postpartum period are thromboembolism and hemorrhage. Multidisciplinary teams, including obstetricians, intervention radiologists, vascular surgeons, anesthetists, and neonatologists, are required for a good obstetric and neonatal outcome.
Validation of optic nerve sheath diameter as a bedside noninvasive tool in comparison with lumbar puncture opening pressure in patients suspected of elevated intracranial pressure
Authors: Nady Amir , El Maraghy Sameh , Sabry Sherif , Mahmoud Hamdy
Published: September 2022

Objective

The aim was to assess the diagnostic accuracy of optic nerve sheath diameter (ONSD) compared with lumbar puncture opening pressure (LPOP) and computed tomography in diagnosing elevated intracranial pressure (ICP) for critically ill patients. Moreover, the study evaluated the diagnostic ability of ONSD as a screening test for cerebral edema.

Background

Recently, linear relationships have been detected between ICP and ONSD, proposing ultrasound measurements as a possible noninvasive method.

Patients and methods

The authors performed a prospective study that included 50 patients with disturbed consciousness of unknown etiology, who were admitted to the ICUs at Beni-Suef University hospital during the period from September 2017 to September 2019. ONSD was measured by ultrasonography.

Results

Measurement of the right ONSD was 0.62±0.084 cm, whereas measurement of the left ONSD was 0.61±0.083 cm. The mean of two eyes was 0.61±0.09 cm, and the LPOP was 19.96±4.69 cmH2O. Overall, 36 (72%) patients had ONSD greater than 0.6 cm. Besides, 31 (62%) patients had LPOP greater than 20 cmH2O. There was a significant positive correlation between average ONSD and LPOP. Receiver operating characteristic (ROC) curve showed that ONSD greater than 0.6 cm had a diagnostic value of elevated ICP with an area under the curve of 0.872 (95% confidence interval: 0.646–0.936) with a sensitivity of 95% and specificity of 77%, with P-value of 0.001. ROC curve analysis was used for prediction of increased ICP using average ONSD compared with CT where the ROC curve showed that ONSD greater than 0.6 cm had a diagnostic value with an area under the curve of 0.606 (95% confidence interval: 0.51–0.72) with a sensitivity of 83% and specificity of 56%, with P-value of 0.028.

Conclusions

ONSD is significant in prediction of elevated ICP, with a good positive correlation with LPOP as a gold standard reference.

Authors: Elmorsy Amr A. , Elweshahi Heba M.T. , Assaad Hany S.H. , Ahmed Mohamed Ahmed F.M. , Beshey Bassem N.
Published: September 2022

Background

Septic shock is considered as a subset of sepsis in which there is marked cellular and circulatory impairment that is associated with higher mortality. It is important to differentiate septic shock from cardiovascular dysfunction and to recognize the effects of cellular abnormalities. The task force stated that there is an agreement that patients who develop septic shock are predicted to have more severe illness with a higher percentage of mortality than having sepsis alone.

Objective

To evaluate the use of a hemodynamic optimization protocol using a ventricular arterial coupling-guided approach for critically ill patients with septic shock.

Patients and methods

This randomized controlled trial was conducted on 100 adult patients who were admitted to the units of the Department of Critical Care Medicine, Alexandria Main University Hospital, with a diagnosis of septic shock requiring mechanical ventilation for 6 months from January 1, to the June 30, 2019.

Results

The results of this study demonstrated significant hemodynamic improvement for the HEMOVACS group. This was illustrated by an increase in mean arterial blood pressure and cardiac output and a decline in serum lactate without an effect on 28-day mortality. The effect of applying the HEMOVACS protocol was preliminarily encouraging, although it was applied for only a single time, at the time of diagnosis.

Conclusion

Early initiation of this protocol at the time of diagnosing septic shock and for follow-up and monitoring may provide better outcomes for patients with septic shock.

Authors: Lintang Dian Saraswati  , Bagoes widjanarko  , Vivi Endar Herawati  , Apriliani Ismi Fauziah
Published: September 2022

BACKGROUND: Channa striata has several good nutrients, including 70% protein, 20% albumin, complete amino acids, zinc, selenium, and iron. However, no study has investigated the chitosan-PEG nanoparticles based on Channa striata protein hydrolyzate. This study’s purpose was to determine the role of 10% Channa striata protein hydrolyzate, chitosan-PEG 4000 nanoparticles, and chitosan- PEG 6000 nanoparticles in reducing diabetes mellitus in diabetic rats.METHOD: A randomized pretest-posttest control group design was used, with male Sprague–Dawley rats being divided into five groups: STZ, acarbose, hydrolyzate, chitosan-PEG 4000 nanoparticles, and chitosan-PEG 6000 nanoparticles. Diabetes was induced by a single injection of streptozotocin at 1 ml in each formulation. Blood glucose levels were analyzed using a glucometer 7, 14, and 21 days after treatment. The CHOD-PAP method was used to analyze the lipid profile. Pancreas and liver histology analyses were carried out using a microscope.RESULTS: The formulation of 10% Channa striata protein hydrolyzate and PEG 6000 was the most effective in lowering blood glucose concentrations, and the response was close to the acarbose result. The glucose concentration decreased after daily oral administration of chitosan-PEG nanoparticles for 21 days. The plasma cholesterol, triglycerides, LDL, and HDL concentrations were lower in treated than in untreated diabetic rats.CONCLUSION: This study concluded that the formulation of 10% Channa striata protein hydrolyzate and chitosan-PEG 6000 nanoparticles was more effective than acarbose.

Authors: Ademe Yonas , Seyoum Nebyou , Lemma Rakeb
Published: September 2022

BACKGROUND: Acute abdomen is a major surgical problem in Ethiopia with surgery for acute abdominal conditions accounting for roughly one-third of total emergency operations in many centers. This study was conducted with the aim of studying the pattern and outcome of surgically managed acute abdominal cases in a private general hospital in Addis Ababa, Ethiopia.Methods: This was a retrospective cross-sectional study of acute abdominal cases in adult patients operated at Teklehaimanot General Hospital between January 1, 2018 and August 1, 2019.RESULTS: A total of 267 patients’ medical records were reviewed. The male to female ratio was 1.5:1 and majority of patients were between the age range of 20 to 40 years with mean age of 36±16 years. The average duration of symptoms before arrival was 71.1±84.4 hours (range 3 to 504 hours) and only 85 (31.8%) of patients reached to the Hospital within 24 hours or less of onset of symptoms. Acute appendicitis was the most common cause of acute abdomen; observed in 193 (72.3%) of the cases. Overall postoperative complication rate was 14.8% and post-operative mortality rate was 1.9%. It was found that delayed presentation (OR 2.01, 95% CI 1.64-7.84), old age (OR 1.51, 95% CI 1.89-3.59), and tachycardia at presentation (OR 2.85, 95% CI 1.03-6.82) were major predictors of morbidity and mortality in operated patients.CONCLUSION: In this study acute appendicitis accounted for the majority of cases operated for acute abdomen. Length of postoperative hospital stay, early post-operative complication rate, and overall mortality rate were found to be significantly lower in our series than other reports.
Splitting blades: why genera need to be more carefully defined; the case for Pyropia (Bangiales, Rhodophyta)
Authors: Zuccarello Giuseppe C. , Wen Xinging , Kim Gwang Hoon
Published: September 2022

The trend in naming genera based almost exclusively on molecular data, and not on morphological diagnostic characters, is increasing. In bifurcating phylogenetic trees generic cut-offs are arbitrary, but at the bare minimum nomenclatural changes should be supported by multiple phylogenetic methodologies using appropriate models for all the various gene partitions, strong support with all branch support methods, and should also result in adding to our knowledge of the interrelationships of taxa. We believe that a recent taxonomic treatment of the genus Pyropia (Yang et al. 2020) into several genera is unwarranted. We reanalysed the data presented in the recent article, using additional phylogenetic methods. Our results show that many of the newly established genera are not well supported by all methods, and the new circumscription of the genus Pyropia renders it unsupported. We also tested additional outgroups, which were previously suggested as sister to Pyropia, but this did not substantially change our conclusions. These generic nomenclatural changes of the previously strongly supported genus Pyropia, do not shed light on the evolution of this group and have serious consequences in these commercially important algae, that are also governed by a plethora of regulation and by-laws that now need to be amended. We suggest that the over-splitting of groups based only on poorly produced and modestly supported phylogenies should not be accepted and that the genus Pyropia sensu Sutherland et al. (2011) be restored.
role of tomato wild relatives in breeding disease-free varieties
Authors: Khazaei Hamid , Madduri@gmail.com Adithya
Published: September 2022

Cultivated tomato (Solanum lycopersicum) is one of the most economically important and widely grown vegetable crops worldwide. However, tomato plants are often affected by biotic and abiotic stresses that reduce yield and affect fruit quality. Phenotypic diversity is evident in cultivated tomatoes, particularly for horticultural traits, but genetic diversity is rather narrow. Major disease resistance genes for different pathogens such as viruses, fungi, bacteria and nematodes are mainly derived from wild tomato species and introgressed into cultivated tomatoes. Here, we list the major disease and insect-pest resistance genes identified in S. pimpinellifolium, S. habrochaites, S. peruvianum, S. chilense, S. pennellii, S. galapagense, S. arcanum and S. neorickii with perspective on the gap between current knowledge on tomato wild relatives and the knowledge that is needed.
Resilience Development in Children with Adverse Childhood Experiences: The Role of the Occupational Therapist and the Interdisciplinary Team
Authors: Frederick Kayla
Published: September 2022

Research has revealed adverse childhood experiences (ACEs) can have a negative effect on a child’s development and put a child at an increased risk of physical and mental health problems in adulthood (Anda et al., 2006; Felitti et al., 1998; Gilbert et al., 2015; Putamen, 2006). Some children have been able to counteract the negative effects of ACEs and achieve positive life outcomes using a principle called resilience (Zolkoski & Bullock, 2012). The current study utilized a virtual survey to examine current interventions used by occupational therapists (OTs) and other members of the interdisciplinary team to assist children in overcoming the negative effects of ACEs. The results of the study found that occupational therapists and the wider interdisciplinary team have utilized the following interventions to assist children in developing resilience: facilitating the development of self-regulation skills and problem-solving skills, utilizing sensory based interventions, utilizing group therapy, utilizing principles of a trauma-informed approach, and referring the child to other professional services (e.g. social worker or psychological services). While many of these interventions were supported by scholarly research, OTs and members of the interdisciplinary team neglected to address multiple key protective factors in childhood resilience. Professionals working with children with ACEs may benefit from additional training in the area of childhood resilience.

Authors: Bolaños Roldán Ana Marcela
Published: September 2022

Introducción. El síndrome de Pfeiffer es un trastorno congénito autosómico dominante que afecta a 1 entre 100.000 nacidos vivos. El objetivo de este reporte de caso es describir la intervención fisioterapéutica en una niña con síndrome de Pfeiffer tipo 2, la cual se basó en el concepto del entrenamiento centrado en tareas específicas, el análisis de cambios en el control postural y la educación y empoderamiento a los padres.
Presentación del caso. Niña que inició tratamiento de fisioterapia con una frecuencia de dos sesiones semanales, desde los 6 meses hasta los dos años, cuando logró deambular por ocho pasos consecutivos de manera independiente. A los 12 meses logró la sedestación independiente, a los 18 meses la niña se ubicó en el percentil 50 según la escala Alberta y a los 24 meses pudo dar ocho pasos seguidos sin asistencia y realizar alcances y manipulación bimanual con objetos modificados.
Conclusión. El entrenamiento basado en tareas y el enfoque centrado en el paciente y su familia permitieron que una niña con síndrome de Pfeiffer tipo 2, con deficiencias en las funciones y estructuras corporales musculoesqueléticas y relacionadas con el movimiento, lograra deambular por 8 pasos de manera independiente a los dos años y se interesara por manipular y explorar su entorno inmediato. La intervención en fisioterapia puede beneficiar a los niños con síndrome de Pfeiffer o síndromes similares, que evolucionan con deficiencias en su neurodesarrollo, mejorando su calidad de vida.
MODIFICATION OF STRUCTURE AND PROPERTIES OF NANOSTRUCTURED VT1-0 TITANIUM ALLOY UNDER ULTRASONIC INFLUENCE
Authors: Savchuk E.S. , Sokolenko V.I. , Karaseva E.V. , Mats A.V. , Frolov V.A.
Published: September 2022

The effect of ultrasonic influence on the structure evolution and creep of nanostructured titanium alloy of the grade VT1-0 obtained by the method of severe plastic deformation has been studied. It is shown that ultrasonic influence with a frequency of f = 20 kHz and an amplitude of 65 MPa leads to relaxation of internal stresses in the nanostructured VT1-0 alloy due to the formation of an equilibrium structure of boundaries without noticeable grain growth. In this case, the mechanical properties of the alloy change as follows: the tensile strength increases, while maintaining the yield strength and ductility. The reason for the observed effect may be the low stacking fault energy of the VT1-0 alloy, which complicates the course of relaxation processes, as well as the rearrangement of the
structure during creep with the formation of new deformation boundaries, which are more resistant to tensile loads.
