In the article considered the problem and treatment of joint hypermobility syndrome of people in different ages, especially of children of the first year of life. The mission of the theoretical study is expected the realization of the system analysis of scientific and methodological literature on the topic, studying methods of examination and reformation of individuals with the joint hypermobility syndrome; identifying the key issues of differential diagnosis of infants with the syndrome of joints hypermobility, burdened with delayed development of general motor skills; analysis of physical rehabilitation of children in the above-mentioned age and nosological category. Methods of the analysis include the theoretical analysis, synthesis and generalization of the literary sources. In the article emphasized the concept of screening and identifying the manifestation of joints hypermobility in individuals of different ages. It demonstrates the necessity of the application of differentiated diagnostic testing of locomotors areas in infants and application of appropriate specific examinations for the objective evaluation of these patients. In particular, there is a proposed use of the following tests: the visual assessment of the child’s arbitrary posture at rest and in motion, test on tone muscles, test for traction, determining whether there are «symptoms of a composite blade» and «symptom of flaccid shoulder», detection of supportive functions of legs, arms, determination and volume resistance of passive movements. Attention focused on the necessity to find a comprehensive physical rehabilitation program for the effective and rapid formation of motor functions in infants. As a result of the theoretical research, it is possible be concluded that the clinical studies of the joint hypermobility syndrome, the consequences of this pathology and directions towards its correction in the literal sources are not enough highlighted. It demands the improvement of methods of the diagnosis delay in motor areas in infants at the presence of joints hypermobility. It is necessary to optimize the programs of physical rehabilitation in infants with the developmental delay of locomotion to prevent complications of their features musculou-ligamentous apparatus.

The article presents a diagnosis of dysplasia of connective tissue in athletes, where the most important are the methods of clinical assessment using diagnostic tests and rating scales manifestation of connective tissue dysplasia. Evaluation of patients with suspected connective tissue dysplasia should include inspection of an ophthalmologist, orthopedic trauma, cardiology. Should also be carried out by criteria diagnosis degree of connective tissue dysplasia by T. Y. Smolnova (2003) (Large and small diagnostic criteria), which include: increased skin extensibility, joint hypermobility (sprain, dislocation and subluxation, flat feet), muscle hypotonia, a hereditary predisposition to the disease, evaluation of signs joint hypermobility (Beighton criteria). If during routine medical examination revealed athletes with manifestations of connective tissue dysplasia, they are subject to a more in-depth examination and observation. Early diagnosis of connective tissue dysplasia allows not only to plan the training process, but also reduces the trauma of athletes.

Full textAbstract:
Abstract The Ehlers-Danlos syndromes (EDS) represent a group of genetically diverse disorders characterized by the variable combination of joint hypermobility, hyperextensibility of the skin, and connective tissue fragility affecting the skin and other organs. Based on clinical features, 13 different types of EDS have been delineated, 12 of which represent monogenic conditions caused by pathogenic variants in 21 confirmed genes. Pathogenesis is related to disturbances of collagen formation and/or stability. No monogenic cause has been identified for hypermobile EDS (hEDS), a more common EDS type, which is unlikely to represent a single gene disorder in the majority of affected individuals and at present cannot be diagnosed by genetic investigations. Here we summarize the clinical features and the molecular bases of the monogenic EDS types, highlight diagnostic challenges, and provide guidance for the molecular work-up of affected individuals. In general, genetic tests are indicated if clinical features suggest a monogenic EDS type but are usually unrewarding for other cases of hypermobility.

The aim of the study was to ascertain information upon the occurrence of hypermobility as well as the symptoms of light brain dysfunction in rhythmic gymnasts and to prove their relationship. The research sample consisted of 78 girls from rhythmic gymnastics teams from the Czech Republic with average age 12,81 ± 2,47. The study used deliberate selection on the basis of chosen criteria: women, age 10 – 18 years, at least 5 let of specialised training in rhythmic gymnastics, week load at least 10 hours. The diagnostics of hypermobility used the method of measuring joint range with the aid of goniometer. The range of the movement of hip joint was measured and Janda test. The diagnostics of mild brain dysfunction diagnostics used orientation brain tests. It is the test of tax, which is aimed upon the proper aiming of movement, test of diadochokinesis, which is aimed at the ability to perform alternating movements, and the test of stability using Romberg pose on a balance platform with open eyes. The results of the goniometric measurement showed a significant flexibility of the gymnasts, mainly in the area of their hip joint (flexe right hip joint 161,09 °; ± 14,78 and flexe left hip joint 158,54 ° ± 14,05). When diagnosing mild brain dysfunction using tax, in both the upper and the lower extremities, no pathology was ascertained, on the contrary, however dysdiadochokinesis was found in 7 gymnasts. The results of the Romberg pose on the balance platform were mildly above the norm (compared with general population), nonetheless, the 7 people with dysdiadochokinesis showed results under the values of the general population. The people with dysdiadochokinesis, also showed worse results in the Romberg pose on the balance platform, as well as the symptoms of hypermobility, which where proved by goniometric examination.

Background:Arthralgia in children for many years continues to maintain the status of the most common symptom of rheumatic diseases. However this symptom should not always be interpreted as a manifestation of arthritis. Well known that arthralgia in growing children is a frequent problem which can be caused by pathological or innocuous process.Objectives:The goal of this study was toanalyze the structure of childhood arthralgia.Methods:Wecarried outaretrospective review of 600children who applied to the outpatient department of the institute with a complaint of pain lasting longer than two months in one or more joints. The clinical, instrumental and laboratory pictures were studied. Special attention was paid to certain aspect of joint pain by the child or his parents. The data obtained made it possible to systematize and detail the nature of the articular pathology in children of various age groups.Results:All children were divided into several groups based on their anatomical and physiological characteristics of osteoarticular system: the first group consisted of 240 children under 6-7 years old, the second group – 220 children 7-12 years old, the third group – 140 children over 12 years old.Research suggests that more preschool children were experience bilateral lower extremity pain by “post-walk genesis” due to natural hypermobility, immaturity of sensory innervation of the joints and imbalance of the leg muscles (e.g. growing pains). The second most common cause was joints pain associated with infectious factor (post-infectious genesis or chronic foci of infection). The frequency of juvenile arthritis and other rheumatic diseases in children of this age group did not exceed 10%. Special attention was paid to nightpain with fever and changes in blood tests to exclude malignancies manifestation and other tumors (less 5%).The most common causes of joint pain of school-age children were hypermobility syndrome and enthesopathy (primary, secondary). Secondary enthesopathy were result of changes in nutrition, rapid growth and excessive exercise. Also enthesopathy were manifestation of endocrine, gastrointestinal or infectious diseases. The proportion of children with the onset of chronic inflammatory arthropathy also did not exceed 10%. Hypermobility child’s syndrome was characterized by harmless pain, linked to physical activity (less morning stiffness).Over the past decade, we’ve seen a gradualincrease in the number of childrenwith diagnosed patellofemoral pain (non-traumatic) and mediopatellar plica syndromes (95% were girls). In most cases children was complicated by syndrome of increased anxiety. Cases of apophysitis as cause of chronic arthralgia were over 15%. The share of true chronic inflammatory arthropathies, including spondylitis, in children of this age group did not exceed 10%. Fibromyalgia were diagnosed less 5%.Conclusion:Despite continuous improvements in examination technique and image quality there is no universal test to diagnose cause of childhood arthralgia. Age features, individual nature of pain perception, the high frequency of incomplete and transient forms of arthropathy, cases atypical joint diseases have been intriguing problems for diagnostic pathology. Integrated assessment modelling framework of the clinical and instrumental pictures with understanding of the anatomical and physiological characteristics of childhood will help identify the true cause of chronic musculoskeletal pain. there is no single test to diagnose CADisclosure of Interests:None declared

Full textAbstract:
Background Generalized joint hypermobility is an inherited collagen phenotype based on clinical assessments of joint mobility. However, there is no international consensus to define generalized joint hypermobility, both considering which joint mobility tests should be included and limits for joint hypermobility. Objectives The primary aim of the study was to identify a subset of joint mobility tests to define generalized joint hypermobility. A further aim was to evaluate standardized limits for the classification of hypermobility in different joint types throughout the body. Methods A total of 255 early pregnant women were included in the study. Joint mobility was measured according to a structured protocol. Correlation and principal component analysis were used to find a subset of joint mobility tests. To classify hypermobility in each joint mobility test, five different standard deviation levels plus 0.84, plus 1.04, plus 1.28, plus 1.64 and plus 2 were used, corresponding to 20%, 15%, 10%, 5% and 2.5% of the normal distribution. Results No subset of joint mobility test could define generalized joint hypermobility. The higher the standard deviation levels, the higher the limit to classify joint hypermobility and the lower the prevalence. As a result of no subset of joint mobility tests were found to define generalized joint hypermobility, different combinations of major and minor joints in upper and lower limbs and the axial skeleton, were systematically developed. These combinations were evaluated for each standard deviation level, resulting in a prevalence of generalized joint hypermobility between 0% and 12.9% and a clear variation in how the hypermobile joint mobility tests were distributed. Conclusion It is probably not possible to choose a subset of joint mobility tests to define GJH. In order not to overlook generalized joint hypermobility, a broader assessment of different joint types and sizes of joints appears to be needed. The prevalence of generalized joint hypermobility is dependent on joint hypermobility limit and the chosen combination of joint mobility tests.

Aim. To mark out the main features of temporomandibular joint dysfunction in patients with benign joint hypermobility syndrome. Methods. 90 patients with temporomandibular joint dysfunction were examined. The first group included 53 (58.89%) patients with benign joint hypermobility syndrome, the second group - 37 patients with temporomandibular joint dysfunction without any signs of benign joint hypermobility syndrome. Functional joint examination including clinical examination, examination of jaw diagnostic models in articulators, X-ray and magnetic resonance imaging, was performed. The diagnosis of benign joint hypermobility syndrome was set up by clinical findings according to national recommendations of Russian Society of Cardiology. Results. Two main trends were found in patients with benign joint hypermobility syndrome. Joint hypermobility was present in 27 (50.94%) out of 53 patients aged 30 years and older. Temporomandibular joint dysfunction in those patients was quite severe, associated with pain and limited range of mandibular movement. In 49.06% of cases in patients with benign joint hypermobility syndrome aged younger than 30 years, bone symptoms were present. Those patients were complaining of joint noises. In 38.46% of cases, gothic palate or frontal teeth crowding were observed. According to magnetic resonance imaging, there was a condylar processes asymmetry at occlusion in 41 (77.36%) patients with benign joint hypermobility syndrome. Conclusion. Clinical and morphologic signs of temporomandibular joint dysfunction in patients with benign joint hypermobility syndrome are associated with predisposed changes in temporomandibular joint capsule and ligaments. Temporomandibular joint dysfunction is a typical and regular feature of benign joint hypermobility syndrome.

Joint hypermobility is common among school-aged children and it may progressively lead to joint pain and developmental delay. Identifying joint hypermobility in school-aged children would facilitate the monitoring of early changes and planning for early rehabilitative intervention. This study aimed to describe gender-related difference in joint hypermobility among school-aged children. A descriptive study was conducted in an elementary school in Surakarta, Central Java, Indonesia. The study subjects were 261 students aged 6 to 12 years selected randomly. The study variables were gender and joint hypermobility. Beighton scale was used to assess joint hypermobility score. Gender-related difference in joint hypermobility among school-aged children was tested using t-test. The results of ≥4 points on Beighton scale was observed in 157 of 261 school-aged children (60.2%). Mean of Beighton score in female children (Mean= 3.87; SD= 0.19) was higher than male chidren (Mean= 4.15; SD= 1.82), but it was statistically non-significant (p= 0.256). It can conclude that there is no difference between gender in joint hypermobility among school-aged children. The need for joint hypermobility screening tests in elementary school children is highlighted.

Objective: To determine frequency of joint hypermobility in patients of fibromyalgia presenting to our institution. Methodology: This observational cross-sectional analytical study was conducted from June 2021 to May 2022 at Department of Medicine & Allied, Azra Naheed Medical College, Superior University, Lahore, Pakistan. Fibromyalgia was defined according to the 1990 ACR diagnostic Criteria of Fibromyalgia. Localized Joint Hypermobility was defined as <3 score and generalized Joint Hypermobility was defined as >4 score on the Beighton Score Scale. The study included 266 patients with fibromyalgia of both sexes aged between 16 years to 35 years. Joint hypermobility was assessed by using Beighton score. Results: Mean age was 26.5+4.6 years with 178 (66.9%) females. Mean BMI was 23.9+3.9 kg/m2. Mean Beighton score was 1.1+2.4. Generalized Joint Hypermobility was seen in 34 (12.8%) patients, 23 (8.6%) had localized hypermobility whereas 209 (78.6%) had no hypermobile joints. Stratification of outcome was done with regards to age (p=0.683), sex (p=0.238) and BMI (p=0.482). Conclusion: This study showed that generalized joint hypermobility was present approximately in one out of every 10 patients and a quarter of patients had at least one clinically documented hypermobile joint.

Full textAbstract:
The sacroiliac joint (SIJ) is a true source of pain commonly tested in osteopathic practice. This study investigated the inter examiner reliability and validity of pain provocation tests at the SIJ. Two examiners tested fifty participants, mean age 23. Sixteen participants were symptomatic for sacroiliac joint dysfunction. Examiners were blinded to participants inclusion criteria and examinations findings. Cohen's kappa and percentage agreement were used to evaluate inter examiner reliability. Validity was measured using sensitivity, specificity, positive and negative predictive values. Percentage agreement between examiners was 76% and Cohen's kappa findings included a kappa = 0.475 overall. Total validity findings included; sensitivity 0.34, specificity 0.93, positive predictive value 0.70 and negative predictive value 0.75. Investigation identified a poor level of validity of pain provocation tests at the SIJ and of inter examiner agreement using compression and gapping tests. A good level of inter examiner agreement occurred using the high thrust and Faber test (k=0.674 0.611 respectively).
This minor thesis was written by a post-graduate student as part of the requirements of the Master of Health Science (Osteopathy) program.

Targeted injections of pharmacological agents around the spine, known as ‘injection therapy’, are among the most commonly offered treatments for medium–long-term back pain. These procedures are typically performed on an outpatient basis, with less requirements for anaesthesia and sterile fields than the more invasive surgical procedures. They may be performed as diagnostic tests, or to give either short- or long-term relief from pain symptoms associated with the spine. This chapter covers a selection of pain clinic procedures, covering facet joint injections, nerve root injections, and epidural/sacral injections under imaging control. Each procedure includes images that demonstrate the position of the C-arm, patient, and surgical equipment, with accompanying radiographs demonstrating the resulting images.

Full textAbstract:
Juvenile idiopathic arthritis (JIA) is defined as arthritis lasting for 6 weeks or more presenting in childhood at any age up to 17 years. Arthritis is diagnosed clinically by the presence of joint pain, stiffness, and swelling with inflammation limiting the range of individual joint movement. There are subtypes that tend to follow distinct courses and with phenotypes that vary widely from a serious systemic inflammatory disorder of systemic JIA to single-joint monoarthritis. The differential diagnosis of JIA is wide and the best chance of long-term remission is where treatment is started as early as possible. However, there is often delay in diagnosis in childhood and there is no single reliable diagnostic test so pattern recognition is fundamental. There are associated disorders such as silent uveitis that must be screened for and managed as part of essential multidisciplinary care. Systemic JIA is complicated by potentially life-threatening macrophage activation syndrome that is often underdiagnosed but where the diagnosis is based on easy clinical tests and where awareness is vital. This chapter covers descriptions of the classification criteria for chronic arthritis in children, clinical presentations and likely course for the various subtypes.

Full textAbstract:
Joint aspiration and microscopic examination of the aspirated synovial fluid remains the gold standard for the diagnosis of calcium pyrophosphate crystal deposition (CPPD). If synovial fluid aspiration is not feasible, plain radiography and/or ultrasound scanning may be used to detect chondrocalcinosis (CC) which predominantly occurs due to calcium pyrophosphate (CPP) crystals, and this can be used as a diagnostic surrogate for CPPD as suggested by the EULAR Task Force. Acute CPP crystal arthritis often associates with a brisk acute phase response (elevated C-reactive protein (CRP) and/or erythrocyte sedimentation rate (ESR), plasma viscosity) and neutrophilia. A mildly raised CRP and/or ESR may be present in chronic CPP crystal inflammatory arthritis. On the contrary, asymptomatic CC, or CPPD with osteoarthritis does not cause raised acute phase reactants. As CPPD most commonly occurs due to increasing age and osteoarthritis, investigations to screen for underlying metabolic abnormalities should be carried out in those with early-onset CPPD (under 55 years), or in those with florid polyarticular CC. As hyperparathyroidism gets more common with ageing its presence should be specifically sought in all age groups. Tests for other predisposing metabolic conditions should only be carried out in the presence of specific clinical features. Genotyping for mutations, especially in the ANKH gene, may be warranted in those with a family history of premature CPPD and no evidence of inherited metabolic predisposition, but such testing is unavailable to most clinicians.

Full textAbstract:
The temporomandibular joint (TMJ), being an almost well-known anatomical structure but its diagnosis may become difficult due to sounds accompanying joint movement. One example is temporomandibular joint hypermobility (TMJH), which still requires comprehensive study. TMJH is a rare disorder; however, its prevalence at the level of around 4% is still significant. We propose a diagnostic method of TMJH based on the digital time-frequency analysis of sounds generated by TMJ. The volunteers were diagnosed using the RDC/TMD questionnaire and auscultated with the Littmann 3200 electronic stethoscopes on both sides of the head simultaneously. Recorded TMJ sounds were transferred to the computer via Bluetooth® for numerical analysis. The research reveals characteristic time-frequency features in acoustic signals which can be used to detect TMJH. This can help differentiate other disc displacements from joint hypermobility.

Abstract Each type of diagnostic test has its proper place in evaluating children with muscle, bone, or joint pain. If a bone is painful, it is appropriate to begin the evaluation (after a complete history is taken and a thorough physical examination is done) with an X-ray radiograph to eliminate the possibility of fracture or structural abnormality. X rays are also useful to determine whether bones are out of alignment or abnormally curved. An X ray may be the only study necessary to establish the diagnosis of a broken bone, slipped capital femoral epiphysis, scoliosis, or many other orthopedic conditions (see Chapter 3). However, for children with juvenile arthritis, lupus, or many other rheumatic conditions, the X ray may be useful only to exclude orthopedic problems.

Full textAbstract:
Non-inflammatory musculoskeletal pain is common in children and adolescents, and when persistent or widespread, can have a negative impact on physical and psychological well-being. Diagnostic labels and criteria are not uniform in the current literature, but musculoskeletal pain may present as widespread pain or juvenile fibromyalgia, complex regional pain syndrome, or in association with joint hypermobility. Chronic musculoskeletal pain, irrespective of its trigger, can bring persistent and recurrent distress, disability, and widespread family disruption. Once serious medical causes have been excluded by history, examination, and relevant investigations, the focus should be on rehabilitation. Multidisciplinary team management to facilitate cohesive working and the introduction of psychological and physical therapies can improve outcome. Further research is required to define the role of pharmacological interventions.

Diagnostic labels and criteria are not uniform in the current literature, but musculoskeletal pain may present as widespread pain or juvenile fibromyalgia, complex regional pain syndrome, or in association with joint hypermobility. Chronic musculoskeletal pain, irrespective of its trigger, can bring persistent and recurrent distress, disability, and widespread family disruption. Once serious medical causes have been excluded by history, examination, and relevant investigations, the focus should be on rehabilitation. Multidisciplinary team management to facilitate cohesive working and the introduction of psychological and physical therapies can improve outcome. Further research is required to define the role of pharmacological interventions.

Full textAbstract:
Periprosthetic joint infection (PJI) is among the most severe complications associated with total joint arthroplasty (TJA), leading to heightened risks of mortality and morbidity, as well as a diminished quality of life for affected individuals. Early and precise diagnosis of PJI is essential to enable effective treatment and improve outcomes. However, identifying PJI remains a formidable challenge due to the lack of a diagnostic test with absolute reliability. This difficulty is particularly pronounced in cases of acute PJI occurring shortly after surgery, where widespread postoperative inflammation and edema complicate the diagnostic process. Currently, the diagnostic framework for PJI involves integrating multiple sources of information, including clinical evaluation, preoperative serological tests, analysis of aspirated joint fluid, and microbiological and histopathological examination of tissues or fluids obtained intraoperatively. Despite these available methods, there is ongoing debate in the medical community regarding standardized diagnostic protocols. Given these complexities, a multidisciplinary approach is essential to ensure comprehensive management of patients with PJI. Collaborative efforts among orthopedic surgeons, infectious disease specialists, microbiologists, and pathologists are critical to achieving accurate diagnosis and effective treatment planning.

Adding technology to clinical diagnosis improves patient care, because objective measurements enhance the patient's report of symptoms and the observations made during an examination. The combination of multiple tests has universally been acknowledged to improve diagnostic sensitivity and specificity, as well as add value to treatment effectiveness monitoring and treatment outcomes. This chapter discusses four dental technologies that objectively measure differing masticatory functions: Surface Electromyography, Magnet-Based 3-Dimensional Electrognathography, Temporomandibular Joint Vibration Analysis, and T-Scan Computerized Occlusal Analysis. Each technology is presented with examples of its output data recorded from both an asymptomatic patient and one demonstrating masticatory system dysfunction. An included case report illustrates how combining these technologies can therapeutically improve a symptomatic Occluso-Muscle Disorder patient's diagnosis and treatment. Finally, recommendations are made that Dental Medicine accept these technologies as an indispensable part of modern clinical practice, so that resistance to their implementation will no longer inhibit their use.

Full textAbstract:
Virtual reality (VR) technologies have the potential to support medical education and training. In order to orient the development of medical VR applications towards the actual deficiencies and demands in orthopedics, we performed a survey among 56 orthopedic physicians. They were asked to provide information about the kind of physical joint evaluation tests which they perform most often, the importance of physical joint evaluation in comparison to alternative diagnostic methods, and their opinion about current medical education system as well as the prospects of VR applications in orthopedics. The main conclusion of this survey is that VR applications have the potential to improve the lacking medical education and orthopedic training, e.g. by improving the quality of joint evaluation methods, reducing the high number of unhealthy, risky and expensive alternative diagnostic procedures.

Full textAbstract:
Introduction: Pompe’s disease is a neuromuscular condition caused by a metabolic disorder of autosomal recessive inheritance. The deficit of acid alpha-glucosidase causes accumulation of glycogen in the lysosomes of the striated and cardiac muscle. It presents in childhood: hypotonia and cardiorespiratory impairment; but at late-onset: axial and waist muscle weakness. Case report: Patient, female, 20 years old, non-consanguineous parents, with good intra-uterus fetal mobility, was born by cesarean delivery weighing 3.7 kilograms and 51 centimeters. She first walked without support and spoke her first words at 13 months of age. By the age of 12, she started progressive thoracolumbar scoliosis and underwent posterior spinal arthrodesis two years later. During the follow-up, muscle weakness was found. Furthermore, she presented macrocephaly, high myopia, fusion of cervical vertebrae, progressive scoliosis, dolichostenomelia and joint hypermobility. Extensive investigation was carried out with laboratory tests that showed CPK elevation, imaging tests and mutation research for facio-scapular-humeral muscular dystrophy and type 2A waistband muscular dystrophy. The incisional biopsy found mixed muscle changes with deposit of amorphous material. Pompe’s disease was confirmed by a significant reduction in alpha-glucosidase activity. The patient evolved with weakness in the legs and fatigue on moderate efforts, but also weakness in the lower limbs, detachable on the right and hyporeflexia, on physical examination. Conclusions: Progressive thoracolumbar scoliosis, refractory to postural and surgical corrections, should be an alert for differential diagnoses. Changes in axial musculature can be suggested and Pompe’s disease, a potentially treatable condition, must become relevant.

In XIV Congresso Paulista de Neurologia. Zeppelini Editorial e Comunicação, 2023. http://dx.doi.org/10.5327/1516-3180.141s1.613.
Full textAbstract:
Cases reports: Two females from different families, 34 and 16 years old, who started at puberty with distal weakness in lower limbs and difficulty in walking. The youngest had a history of parental consanguinity. The oldest also developed symptoms of cerebellar ataxia. Both patients had joint hypermobility. After physical exercise, both showed increased serum levels of creatine phosphokinase, but only one of them showed increased lactate. Both electroneuromyography showed motor neuropathy, predominantly in lower limbs, with axonal and demyelinating pathophysiology, with probable superimposed pre-ganglionic involvement. Both genetic tests showed homozygous pathogenic variation in COQ7 gene, described as Chr16:19.067.667, which leads to methionine substitution and impaired protein traduction. Discussion: Primary COQ10 deficiency is a heterogeneous group of mitochondrial disorders caused by defects in proteins involved in COQ10 biosynthesis. It’s inheritance usually is autosomal recessive. Mutations in 10 genes directly involved in coenzyme Q10 synthesis and collectively named “COQ genes” have been identified. Clinical spectrum may overlap encephalomyopathies, ataxia, neuromyopathy, spastic paraplegia and even impairment of another organs. Only four COQ7 deficiency patients have been reported so far. In addition, cases reported here are related with a new variation in COQ7 gene. All reported COQ7 deficiency patients have asian ancestry, which is not the case of patients related here. Some improvement can occur by COQ10 supplementation, which was initiated in both cases. Conclusion: The diagnosis of primary COQ10 deficiency is limited by factors like rarity, heterogeneous phenotypes and unavailability of genetic testes, which favors under or misdiagnosis. Discovery of new cases and mutations can increase our knowledge about this condition, make possible the diagnosis, consequently look for dysfunction of other organs and try a specific treatment.

Full textAbstract:
Kyphoscoliotic Ehlers-Danlos syndrome (kEDS) is a genetic collagen disorder, with early onset hypotonia, weakness, progressive kyphoscoliosis, joint hypermobility, and other features underlying connective tissue involvement. On the other hand, congenital myopathies (CMs) are genetic muscle disorders, with hypotonia and weakness usually from birth which can associate with skeletal deformities. Case 1: RSS, 2-year-old, male. At birth, hip dysplasia and global hypotonia. On examination, proximal tetraparesis, global hyporeflexia and hypotonia, joint hypermobility, ogival palate, umbilical hernia, scoliosis and clubfoot. Genetic testing: Homozygous pathogenic variant in the FKBP14 gene (ENST0000000222803- c.362_363insC, p.Glu122Argfs*7), associated with kEDS type II. Case 2: RRO, 37-year-old, female. Global hypotonia at birth with congenital hip dislocation. On examination, mild proximal weakness, global hyporeflexia, joint hypermobility, scoliosis and ogival palate. Absence of marfanoid habitus. Genetic testing: Homozygous pathogenic variant in the PLOD1 gene (ENST00000196061-c.2032G>A, p.Gly678Arg), associated with kEDS type I. Conclusion: Uncommon clinical features in CMs should alert for an alternative diagnosis. Extreme joint laxity is more often a sign of a connective tissue disease, and can be associated with Marfanoid habitus, arterial dissection, bluish sclerae, umbilical hernia. Both patients presented nonspecific findings like neonatal skeletal deformities, hypermobility and mild weakness. A wide genetic test was definitive for the correct diagnosis. EDS must be included in the differential diagnosis of congenital myopathies, especially when associated with involvement of connective tissue. This is very relevant in the management care of the patients.

Full textAbstract:
In this contribution, an on-line engine performance monitoring is carried out through an engine health parameter estimation based on several gas path measurements. This health parameter estimation makes use of the analytical redundancy of an engine model and therefore implies the knowledge of the engine state. As the latter is a priori not known the second task is therefore an engine state variable estimation. State variables here designate working conditions such as inlet temperature, pressure, Mach number, rotational speeds, … Estimation of the state variables constitutes a general application of the Extended Kalman Filter theory, while the health parameter estimation is a classical recurrent regression problem. Recent advances in stochastic methods [1] show that both problems can be solved by two Kalman filters working jointly. Such filters are usually named Dual Kalman Filters. The present contribution aims at using a dual Kalman filter modified to provide robustness. This procedure should be able to cope with as much as 20 to 30% of faulty data. The resulting online method is applied to a turbofan model developed in the frame of the OBIDICOTE 1 project. Several tests are carried out to check the performance monitoring capability and the robustness that can be achieved.

Determination of contact forces exchanged between wheel and rail is one of the most important topics in railway dynamics. Recent studies are oriented to improve the existing contact methods in terms of computational efficiency on one side and on the other side to develop more complex and precise representation of the contact problem. This work shows some new results of the contact code developed at Politecnico di Torino identified as RTCONTACT; this code, which is an improvement of the CONPOL algorithm, is the result of long term activities, early versions were used in conjunction with MBS codes or in Matlab® environment to simulate vehicle behaviour. The code has been improved also using experimental tests performed on a scaled roller-rig. More recently the contact model was improved in order to obtain a higher computational efficiency that is a required for the use inside of a Real Time process. Benefit of a Real Time contact algorithm is the possibility to use complex simulation models in diagnostic or control systems in order to improve their performances. This work shows several comparisons of the RTCONTACT contact code respect commercial codes, standards and benchmark results.

Full textAbstract:
The identification of two-phase flow patterns has been widely studied, and the diagnostic procedures are traditionally based on statistical or spectral signal analysis, while the spatial information related with the geometrical topology of the phase distribution in the pipe is never taken into account. The aim of this study is to demonstrate how the exploitation of both spectral and spatial information leads to an unambiguous identification of the flow patterns. Experiments are performed on a 30 meters long horizontal air-water loop. By simultaneously analyzing the power spectral density of the signals delivered by a multi-electrode impedance sensor, we obtain a space-frequency representation which exhibits particular features of the different flow regimes. They can be characterized by a set of 3 scalar parameters, quantifying respectively the localization in space, in frequency and the shape of the spectral content. The final demonstration of this space-frequency characterization is provided by the use of a multi-layer neural network, trained on a 80 tests database. This net exhibits a successful identification rate above 80% when used in blind real-time tests.

Full textAbstract:
A diagnostic tool based on Feed Forward Neural Networks (FFNN) is proposed to detect the origin of performance degradation in a Combined Cycle Gas Turbine (CCGT) power plant. In such a plant, due the connection of the steam cycle to the gas turbine, any deterioration of gas turbine components affects not only the gas turbine itself but also the steam cycle. At the same time, fouling of the heat recovery boiler may cause the increase of the turbine back-pressure, reducing the gas turbine performance. Therefore, measurements taken from the steam cycle can be included in the fault variable set, used for detecting faults in the gas turbine. The interconnection of the two parts of the CCGT power plant is shown through the fingerprints of selected component fault models for a power plant composed of a heavy-duty gas turbine and a steam plant with a single pressure recovery boiler. The diagnostic tool is composed of two FFNN stages: the first network stage is addressed to pre-process fault data in order to evaluate the influence of the single fault variable on the single fault condition. The second FFNN stage detects the fault conditions. Tests with simulated data show that the the diagnostic tool is able to recognize single faults of both the gas turbine and the steam plant, with a high rate of success, in case of full fault intensity, even in presence of uncertainties in measurements. In case of partial fault intensity, faults concerning gas turbine components and the superheater, are well recognized, while false alarms occur for the other steam plant component faults, in presence of uncertainties in data. Finally, some combinations of faults, belonging either to the gas turbine or the steam plant, have been examined for testing the diagnostic tool on double fault detection. In this case, the network is applied twice. In the first step the amount of the fault parameters that originate the primary fault are estimated. In the second step, the diagnostic tool curtails the contribution of the main fault to the fault parameters, and the diagnostic process is reiterated. In the examined fault combinations, the diagnostic tool was able to detect at least one of the two faults in about 60% of the cases, even in presence of uncertainty in measurements and partial fault intensity.

Full textAbstract:
Abstract Fluctuating pressures can induce vibration in the Electric Submersible Pump (ESP) and severely affect the pump components. The installation depths of ESP systems are varying from a few meters to several hundred meters. Once installed ESPs are not accessible for diagnostic measurement and maintenance activity, so it becomes necessary to obtain detailed information of mean and fluctuating pressures to attain an optimal pressure distribution inside the pump. In this paper the results obtained from an experimental investigation of stage-wise pressure pulsation at Best Efficiency Points at various speeds are presented. Tests were conducted on a five stage ESP having impellers of 121 mm diameter and 14 mm width at outlet with impeller of 8 vanes and a diffuser-return channel of 6 vanes which delivers 7 lps (litres per second) and develop 60 m total head at various speeds. Unsteady pressure signals were captured by mounting piezoresistive transducers at each stage of ESP. Captured pressure signals were converted into frequency domain to analyze the characteristics of pressure pulsation. The results have indicated that the maximum amplitude of pressure pulsation was obtained at the highest operating speed setting of 60 Hz at stage 4. The normalized frequency at which this amplitude was maximum was highest at stage 2 at all the speeds.

Full textAbstract:
The performance of military ground vehicle systems is being degraded due to high operation tempo and exposure to extreme environments while performing in-theater service. To address this issue, the US Army is implementing a policy of Condition Based Maintenance which is supported by the Army Material System Analysis Activity (AMSAA). The vision of this policy is to base the maintenance of systems upon the actual condition of the system and not upon time- or distance-based schedules. This capability will be enabled by the application of usage, diagnostic and prognostic processes executed on a Health and Usage Monitoring System (HUMS) installed on these vehicle systems. A thorough understanding of the ways in which the system condition is degenerated and the ability of the HUMS to detect, identify, and communicate all conditions that require maintenance in a timely manner are key requirements of these processes. Seeded Fault Testing is the critical means of fulfilling these requirements. A joint Seeded Fault Testing project between AMSAA and the US Army Aberdeen Test Center (ATC) has been initiated to gain a thorough understanding of ground vehicle system condition degeneration and HUMS implementation of products and processes that can accurately identify and communicate it. A military vehicle underwent exhaustive testing in support of this project. The vehicle was subjected to specific use scenarios while carefully controlled faults are induced in engine, transmission, and other key mechanical subsystems that would degrade vehicle performance and degenerate system condition. The vehicle’s induced faults included lowered coolant levels to simulate leakage, restriction of air flow across radiators and filters to simulate dust and debris accumulation, and lowered transmission and engine oil levels to simulate leakage and usage. The objective of this project was to use the results from the seeded fault tests to establish critical thresholds, trends, and patterns that will be the basis of the creation and implementation of real-time HUMS-based algorithms that predict faults, warn operators and maintainers of imminent failures, and provide a sound foundation for Condition Based Maintenance.
