Postural Analysis Using Rasterstereography and Inertial Measurement Units in Volleyball Players: Different Roles as Indicators of Injury Predisposition.

Background and Objectives: Acute and chronic injuries are frequent in volleyball. Biomechanics of sport-specific tasks can influence the risk of injury, which is also related to specific court positions. We investigated posture at raster-stereography, balance, and dynamic tasks using inertial motion units to find differences between roles, which can be predictive of a higher risk of injury. Materials and Methods: We cross-sectionally evaluated amateur volleyball athletes. Participants were divided into roles as outside hitters, setters, middle blockers, and opposite hitters. We excluded the "libero" position from our analysis. Results: Sixteen players were included in the analysis. A statistically significant difference was found in left lower limb stiffness among the outside hitter and setter groups. Conclusions: Differences in stiffness might be related to the different training and the different abilities among the two groups. Raster-stereography is extending its indications and should be implemented for non-invasive postural analysis. The use of inertial motion units provides objective measurements of variables that could go unrecognized within a clinical evaluation; its use should be considered in injury preventive programs.

Hemp Seed Oil in Association with ß-Caryophyllene, Myrcene and Ginger Extract as a Nutraceutical Integration in Knee Osteoarthritis: A Double-Blind Prospective Case-Control Study.

Background and Objectives: Nutraceuticals are gaining more and more importance as a knee osteoarthritis (KOA) complementary treatment. Among nutraceuticals, hemp seed oil and terpenes are proving to be very useful as therapeutic support for many chronic diseases, but there are still few studies regarding their effectiveness for treating KOA, both in combination and separately. The aim of this study is thus to compare the effect of two dietary supplements, both containing hemp seed oil, but of which only one also contains terpenes, in relieving pain and improving joint function in patients suffering from KOA. Materials and Methods: Thirty-eight patients were recruited and divided into two groups. The control group underwent a 45 day treatment with a hemp seed oil-based dietary supplement, while the treatment group assumed a hemp seed oil and terpenes dietary supplement for the same period. Patients were evaluated at the enrollment (T0) and at the end of treatment (T1). Outcome measures were: Numeric Rating Scale (NRS), Oswestry Disability Index (ODI), Short-Form-12 (SF-12), Knee Injury Osteoarthritis Outcome Score (KOOS), and Oxford Knee Score (OKS). Results: All outcome measures improved at T1 in both groups, but NRS, KOOS and OKS had a greater significant improvement in the treatment group only. Conclusions: Hemp seed oil and terpenes resulted a more effective integrative treatment option in KOA, improving joint pain and function and representing a good complementary option for patients suffering from osteoarthritis.

Impact of COVID-19 on the mental health in a cohort of Italian rehabilitation healthcare workers.

The COVID-19 pandemic has had a strong impact on healthcare workers (HCWs), affecting their physical and mental health. In Italy, HCWs have been among the first exposed to unprecedented pressure, dealing with large numbers of infections during the first pandemic wave. However, the severe psychological consequences on HCWs find little evidence in the literature, especially in terms of comparison to the status quo ante pandemic. The aim of this study was to provide an assessment of the mental health burden in a cohort of Italian HCWs during the COVID-19 pandemic, comparing their condition with that before the emergency, to direct the promotion of mental well-being among HCWs worldwide. In this retrospective study, we included physicians, physical therapists, and nurses working in the Respiratory Intensive Care Unit, Neurology Unit, and Rehabilitation Unit from a Southern Italy University Hospital. All study participants underwent a battery of psychological tests, aimed at verifying their state of mental health during the COVID-19 emergency and before it. Depressive, anxiety, and burnout symptoms were assessed using the following questionnaires: Maslach Burnout Inventory, Patient Health Questionnaire-9 (PHQ-9), and General Anxiety Disorder-7. Depressive, anxiety, and burnout clinical relevance symptoms were present in HCWs during the COVID-19 pandemic more than those before the emergency. Fifty percent of the HCWs obtained a score clinically significant during the emergency. Moreover, a depersonalization factor showed a statistically significant increase in average scores (p < 0.0001). The PHQ-9 scale showed that 47.1% of the operators reported depressive state presence. The number of operators scoring above the cut-off for the anxiety scale tripled during the emergency (p < 0.0001). The female gender conferred greater risks for depression. Taken together, the findings of this study showed that our sample of Italian HCWs showed a greater risk for depression, anxiety, and stress during the COVID-19 pandemic. These data might be a starting point to plan mental health monitoring and prevention programs for HCWs, thus ensuring patients receive the best possible care performances even during healthcare crises such as the current pandemic.

Anatomy and ultrasound imaging of the tibial collateral ligament: A narrative review.

Medial knee pain is commonplace in clinical practice and ultrasound assessment of the tibial collateral ligament-medial meniscus complex is increasingly becoming a valuable examination tool in the outpatient setting. In the pertinent literature, basic sonographic protocols have been proposed to evaluate the medial compartment of the knee joint. Using high-frequency ultrasound probes and high-level ultrasound machines; we matched the histo-anatomical features of the tibial collateral ligament-medial meniscus complex and its different sonographic patterns in physiological/pathological conditions to define a standardized (layer-by-layer) sonographic approach. Moreover, high-sensitive power Doppler assessments have also been performed to evaluate the nearby microcirculation. Modern ultrasound equipment appears to provide optimal "sonographic dissection" of the tibial collateral ligament-medial meniscus complex for its various physiological/pathological patterns. Likewise, high-sensitive power Doppler allows clear visualization of the microcirculation as regards the local ligamentous and capsular structures. In clinical practice, using adequate technological equipment, a detailed sonographic assessment of the tibial collateral ligament-medial meniscus complex can be performed. High-frequency B-mode ultrasound imaging and high-sensitive power Doppler perfusion patterns can be matched/integrated with the clinical findings to optimize the management of patients with medial knee pain.

The Effect of Physical Exercise on Cognitive Impairment in Neurodegenerative Disease: From Pathophysiology to Clinical and Rehabilitative Aspects.

Neurodegenerative diseases are a group of pathologies that cause severe disability due to motor and cognitive limitations. In particular, cognitive impairment is a growing health and socioeconomic problem which is still difficult to deal with today. As there are no pharmacologically effective treatments for cognitive deficits, scientific interest is growing regarding the possible impacts of healthy lifestyles on them. In this context, physical activity is gaining more and more evidence as a primary prevention intervention, a nonpharmacological therapy and a rehabilitation tool for improving cognitive functions in neurodegenerative diseases. In this descriptive overview we highlight the neurobiological effects of physical exercise, which is able to promote neuroplasticity and neuroprotection by acting at the cytokine and hormonal level, and the consequent positive clinical effects on patients suffering from cognitive impairment.

Pharmacological Treatment for Acute Traumatic Musculoskeletal Pain in Athletes.

Pain management is a crucial issue for athletes who train and compete at the highest performance levels. There are still evidence gaps for the use of analgesics for sports injuries despite the growing interest in training and competition settings. However, high-quality research is needed to determine the most appropriate and optimal timing and formulations in non-steroidal anti-inflammatory drug and opioid management, particularly given the strictness of anti-doping regulations. Indeed, the role of pharmacological therapy in reducing acute traumatic pain in athletes should still be addressed to minimize the timing of return to sport. Therefore, the aim of this comprehensive review was to summarize the current evidence about pain management in the setting of acute injury in elite athletes, providing the most informed strategy for pain relief and performance recovery.

The Effectiveness of Combining Botulinum Toxin Type A and Therapeutic Exercise in Treating Spasticity in a Patient with Complicated Stiff-Person Syndrome: A Case Report.

Stiff-person syndrome is rare and disabling autoimmune condition that most frequently affects women, with no real predisposition by race. Diagnosis is often arduous, which is why patients concomitantly suffer from anxiety and depression. To date, drug therapy is based on the use of benzodiazepines, barbiturates, and baclofen. Refractory cases are treated with intravenous immunoglobulin, plasmapheresis, B lymphocyte depletion with rituximab, and even the implantation of intrathecal baclofen devices. Botulinum toxin injection is frequently used, even if it still has an unclear role in the literature. Our case report aims to demonstrate the efficacy of a combined treatment of botulinum toxin and therapeutic exercise in a 65-year-old patient with biceps brachii muscle hypertonia and diffuse spasms of the axial musculature, using rating scales such as the Numeric Rating Scale (NRS) and Modified Ashworth Scale (MAS), joint range of motion (ROM) measurement, and muscle dynamic stiffness mensuration, which is performed by using the MyotonPro®. All the assessments were conducted at the first evaluation (T0), soon after the combined treatment with botulin toxin and therapeutic exercise (T1), three months (T2), six months (T3), and eight months after the botulinum toxin injection (T4). The patient demonstrated benefits for more than 6 months with no side effects. The combined therapy of botulinum toxin and therapeutic exercise had an excellent result in our patient.

Comparing endoscopic and conventional surgery techniques for carpal tunnel syndrome: A retrospective study.

Introduction: This study aimed to compare the effectiveness of endoscopic carpal tunnel release (ECTR) versus open carpal tunnel release (OCTR) in treating carpal tunnel syndrome (CTS), focusing on symptom relief, functional recovery and post-operative complications. Methods: A retrospective analysis was conducted on 44 patients diagnosed with CTS, randomly assigned to undergo either ECTR (n=23) or OCTR (n=21). Parameters evaluated included post-operative pain, grip strength, functional status using the Disability of the Arm, Shoulder and Hand (DASH) score and time to return to work. Results: Patients who underwent ECTR demonstrated superior functional recovery and quicker return to daily and work activities compared to those in the OCTR group. Grip strength improvement post-surgery showed no significant difference between the groups. However, ECTR patients reported significantly lower DASH scores and faster return to work, indicating better outcomes. There were fewer reports of post-operative complications and scar sensitivity in the ECTR group. Conclusion: ECTR provides an effective alternative to OCTR for CTS treatment, with advantages in functional recovery speed, reduced post-operative discomfort and faster return to work. These findings support the adoption of ECTR as a preferred surgical approach for CTS, highlighting its potential to improve patient outcomes with minimal complications.

Effects of Intradermal Therapy (Mesotherapy) on Bilateral Cervicobrachial Pain.

BACKGROUND: Mesotherapy is a procedure or a process of injecting drugs into the skin. This technique can help decrease the total drug dose due to its drug-sparing effect on the systemic route and can be utilized to treat nonspecific neck pain that occurs in the lateral and posterior neck. METHODS: Ten patients with bilateral cervicobrachial pain were recruited and evaluated at T0 before treatments, T1 at the end of the treatment (42 days after T0), and T2 (72 days after T0). Assessments consisted of performing the Visual Analogue Scale (VAS) to evaluate pain evolution; a range of movement (ROM) and Bilateral trapezius' tone, elasticity, and dynamic stiffness mensuration were performed using MyotonPro®. All patients underwent mesotherapy treatment in the trapezius muscles with 1 cc of Diclofenac Sodium and 1 cc of lidocaine diluted in 3 cc of saline for a total of 6 weeks. RESULTS: VAS value statistically decreased at T1 and T2; ROM of neck flexion statistically increased at T1 and T2, and miometric tone and stiffness value statistically improved at T1 and T2. CONCLUSION: mesotherapy with Diclofenac Sodium reduced pain intensity and improved functional outcomes, with no significant adverse effects in patients with myofascial pain syndrome of cervicobrachial localization.

Intrathecal Baclofen Infusion-Botulinum Toxin Combined Treatment Efficacy in the Management of Spasticity due to Cerebral Palsy.

BACKGROUND: Cerebral Palsy (CP) is a group of permanent, but not unchanging, disorders of movement and/or posture and motor function, which are due to a non-progressive interference, lesion, or abnormality of the developing/immature brain. One clinical presentation is muscle spasticity, which leads to a significant impact on the individual's functionality and quality of life. Spasticity treatment is multidisciplinary and includes pharmacological and physical intervention; intrathecal baclofen shows a positive effect in severe spasticity and suboptimal response to oral drugs, while local injection of Botulinum toxin type A (BTXA) improves muscle tone, motion and pain. OBJECTIVE: The aim of this study was to evaluate the efficacy of the combined intrathecal baclofen infusion (ITB) - botulinum toxin treatment in the management of spasticity in CP. METHODS: 8 patients with spastic tetraparesis were enrolled. All patients were treated with intrathecal Baclofen; in lower limbs, no spastic symptoms appeared, while marked spasticity was noted in upper limbs. We injected the right and left Biceps Brachial (BB) and Flexor Digitorum Superficialis (FDS) muscles with botulinum toxin type A. All patients underwent Myometric measurement, Ashworth Scale, Numerical Rating Scale, and Visual Analogic Scale evaluation before infiltration (T0), 30 days after injection (T1), 60 days after injection (T2), and 90 days after treatment (T3). RESULTS: All data demonstrated an improvement in spasticity, pain, quality of life, and self-care during the study, with p < 0.05. No side effects appeared. CONCLUSION: This study demonstrated the efficacy and safety of intrathecal baclofen infusion and botulinum toxin combined treatment in the management of spasticity, pain, quality of life, and selfcare in CP patients.

How does classification score affect falls in wheelchair basketball? A video-based cross-sectional study on the Italian national team during the European Para Championships 2023.

OBJECTIVES: The aim of this study was to investigate the mechanism of falls in male elite wheelchair basketball (WB) players and to analyse the falls characteristics considering their classification score which ranges from 1.0 to 4.5 and it is related to their functional capacity and particularly to their volume of action. DESIGN: A cross-sectional video analysis was conducted using European para championships 2023official match videos. SETTING: Players of the sample team were divided into 2 groups according to their classification point: low-point players (LPP) and high-point players (HPP). Every occurred fall was systematically analysed focusing on falling related characteristics and game circumstances. PARTICIPANTS: Twelve WB players of the Italian national team. MAIN OUTCOME: Number of falls and mechanism of falls. RESULTS: The results showed a higher number of falls for HPP and highlighted a statistically significant differences between LPP and HPP for the fall direction, the playing time and the first anatomical site in contact with the floor. CONCLUSION: Results reported significant differences between LPP and HPP in terms of mechanism of fall. Further studies should focus on the development of new preventive training strategies tailored to WB players with different levels of impairments to reduce fall related injuries.

Safety and Efficacy of Ultrasound-Guided Perineural Hydrodissection as a Minimally Invasive Treatment in Carpal Tunnel Syndrome: A Systematic Review.

Ultrasound-guided perineural hydrodissection (HD) is a novel technique that has been found to be effective in providing mechanical release of perineural adhesions and decompression of the nerve, reducing inflammation and edema and restoring its physiological function. It has a significant impact on chronic neuropathic pain (20 ± 4 weeks with VAS < 5 or VAS diminished by 2 points after the procedure). Carpal tunnel syndrome (CTS) is a common entrapment mononeuropathy, and its distribution is typically innervated by the median nerve. Patients with mild or moderate CTS may benefit from nonsurgical treatments or conservative therapies. This review was conducted following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement guidelines. Four investigators assessed each title, abstract, and full-text article for eligibility, with disagreements being resolved by consensus with two experienced investigators. The qualitative assessment of the studies was carried out using the modified Oxford quality scoring system, also known as the modified Jadad score. Furthermore, risk of possible biases was assessed using the Cochrane collaboration tool. The results of this review suggest that US-guided HD is an innovative, effective, well-tolerated, and safe technique (11 out of 923 patients had collateral or side effects after the procedure). However, further studies comparing all drugs and with a larger sample population are required to determine the most effective substance.

Medial or Lateral, That Is the Question: A Retrospective Study to Compare Two Injection Techniques in the Treatment of Knee Osteoarthritis Pain with Hyaluronic Acid.

Background: Mild-to-moderate knee osteoarthritis (KOA) can be successfully treated using intra-articular hyaluronic acid (IA-HA). The medial infrapatellar (MIP) approach and lateral infrapatellar (LIP) approach are two of the most used techniques for performing IA-HA, but it is still not clear which one is preferable. Objectives: The study aims to find the best knee injection technique between MIP and LIP approaches. Methods: In total, 161 patients were enrolled, divided into two groups (MIP or LIP). Each technique was performed once a week for three weeks. Patients were evaluated using the Numeric Rating Scale (NRS), Knee Injury and Osteoarthritis Outcome Score (KOOS) and Roles and Maudsley Score (RMS) at T0 (before the first injection), T1 (one week after the third injection) and T2 (six months after). Results: NRS, KOOS and RMS showed a statistically significant improvement in both groups at all the detection times, without significant differences. No differences were detected between the groups in terms of systemic effect effusions, while the MIP group presented a mildly higher number of bruises in comparison with the LIP group (p = 0.034). Conclusions: Both the IA-HA techniques are equally effective in measured outcomes. The MIP approach seems to produce some local and transient side effects. So, the choice of the LIP or MIP approach depends on the operator's skill and experience.

Use of Autologous Conditioned Serum (ACS) for Osteoarthritis Treatment in Horses: A Systematic Review of Clinical Data.

The utilization of Autologous Conditioned Serum (ACS) for treating osteoarthritis (OA) in horses has seen a notable increase in recent years. In vitro studies have consistently identified ACS as a promising therapy for OA joints, contributing to its growing popularity in OA treatment. Despite this, there is a noticeable absence of systematic reviews focused solely on the clinical data of OA patients treated with ACS, excluding the in vitro perspective. This study aims to address this gap by systematically reviewing the latest literature, concentrating solely on clinical data in in vivo studies to evaluate the efficacy of ACS in OA lesions. All clinical studies involving ACS treatments for horses with OA were included in the assessment. Surprisingly, only six trials met the inclusion criteria for this systematic review. The results indicate that the majority of the considered articles support the use of ACS as a treatment for horses, albeit with a control group provided in only one study. However, the absence of a control group and the exclusion of histological evaluation diminish the validity of the majority of clinical research. While several studies suggest a beneficial effect of ACS on OA horses without significant adverse effects, this systematic review affirms that there is no definitive evidence for its effectiveness. Therefore, further investigation of the efficacy of ACS products as a treatment for OA is warranted, emphasizing the need for more controlled trials. Poorly designed and biased studies, lacking blinding or control and adopting inadequate outcome measures, may favor positive results and, thus, necessitate a more rigorous approach to validate the efficacy of ACS in OA treatment.

Low Back Pain and Radiofrequency Denervation of Facet Joint: Beyond Pain Control-A Video Recording.

Chronic low back pain is often due to L5S1 instability resulting in facet joint syndrome. Patients suffering from low back pain may also have a gait pattern characterized by a reduced speed and a shorter, asymmetrical step in order to reduce pain. This case is of a patient with L5S1 instability that occurred after L1 to L5 lumbar stabilization who was treated with radiofrequency (RF) denervation of the medial branch of L5S1 bilaterally. RF ablation outcome was tested by comparing its impact on pain, function, quality of life, and on gait pattern, before and 1 month after the procedure. To objectify the impact of a good pain control on gait, a video recording was performed (see Video 1).

Could Hyaluronic Acid Be Considered as a Senomorphic Agent in Knee Osteoarthritis? A Systematic Review.

BACKGROUND: Knee osteoarthritis (KOA) is one of the most common causes of disability in elderly patients and tends to be a major burden on social and health care spending. Despite its severe socioeconomic impact, KOA remains, to date, an incurable disease. Due to its proper characteristics, KOA represents a favorable disease model for experimenting with senotherapeutics, a group of treatments that counteract the development of age-related disorders and chronic diseases. In recent years, the use of intra-articular hyaluronic acid (IAHA) in the treatment of diseases related to the wear and tear of the articular cartilage has been gaining popularity. Given its ability in joint lubrification, shock absorption, and cell signaling, our aim is to investigate, through the existing scientific literature, its potential role as a senomorphic agent, emphasizing its crucial function in KOA patients. Indeed, senomorphics are a particular group of senotherapeutics capable of modulating the functions and morphology of senescent cells to those of young cells or delaying the progression of young cells to senescent cells in tissues. METHODS: A search in the scientific literature (PubMed, Cochrane Library, and Google Scholar) was carried out from 2019 to 2023, thus the last 5 years. RESULTS: One hundred thirty-eight articles were found concerning the role of hyaluronic acid injections in KOA patients. In these studies, its therapeutic efficacy, its anti-inflammatory properties, and its low risk of side effects emerged. CONCLUSION: IAHA injections are a valuable treatment option for KOA while they can provide pain relief, improve joint function, and slow the progression of joint degeneration. The inhibitory effect of HA on MMP13 and its action as a senomorphic agent suggests that it may have additional benefits beyond its lubricating and shock-absorbing properties. In order to clarify its mechanisms of action and to optimize its clinical use, further studies are definitely needed.

From Histopathology to High-Resolution Ultrasound Imaging of Skin Scars.

Nowadays, modern ultrasound machines and high-frequency transducers allow us to accurately assess the superficial soft tissues of the human body. In this sense, sonographic evaluation of the skin and related pathologies is progressively growing in the pertinent literature. To the best of our knowledge, a standardized sonographic protocol focused on the assessment of pathological skin scars is still lacking. As such, the main purpose of the present study was to propose a technical guide to sonographically assess skin scars in the daily practice of clinicians-starting from knowledge on their histopathological features. In order to standardize the ultrasound examination, a superficial-to-deep, layer-by-layer approach has been proposed to optimize its reproducibility and to promote a common language among the different healthcare providers.

Ultrasonography for Injecting (Around) the Lateral Epicondyle: EURO-MUSCULUS/USPRM Perspective.

Lateral epicondylitis (LE) is a very common and painful condition seen in the daily practice of musculoskeletal physicians. Ultrasound-guided (USG) injections are commonly performed to manage the pain, promote the healing phase, and plan a tailored rehabilitation treatment. In this aspect, several techniques were described to target specific pain generators i the lateral elbow. Likewise, the aim of this manuscript was to extensively review those USG techniques together with the patients' pertinent clinical/sonographic features. The authors believe that this literature summary could also be refined as a practical, ready-to-use guide for planning the USG interventions of the lateral elbow in clinical practice.

With or without straps? A pilot study to investigate whether restraint devices affect the wheelchair basketball players' performance.

BACKGROUND: Wheelchair basketball (WB) represents a great physical activity, rehabilitation, and integration opportunity for people with disability. Straps are wheelchair accessories used to ensure safeness and stability. Nevertheless, some athletes report feeling limited in movements because of these restraint devices. The aim of this study was thus to deepen whether straps could affect performance and cardiorespiratory effort in WB players' athletic gesture and furthermore whether sport performance could be influenced by experience, anthropometric features, or classification score. METHODS: Ten WB elite athletes were enrolled in this observational cross-sectional study. Speediness, wheelchair maneuverability, and sport-specific skills were evaluated with 3 tests: 20-m straight line test (test 1), figure 8 test (test 2), and figure 8 with ball test (test 3); all tests were performed with and without straps. Cardiorespiratory parameters (blood pressure [BP], heart rate, and oxygen saturation) were registered before and after tests. Anthropometric data, classification score, and practice's years were collected and compared with test results. RESULTS: Performance significantly improved in all tests wearing straps (test 1 P = 0.007, test 2 P = 0.009, and test 3 P = 0.025). No significant variation in cardiorespiratory basic signs emerged before and after the tests, with or without straps (systolic BP P = 0.140, diastolic BP P = 0.564, heart rate P = 0.066, and oxygen saturation P = 0.564). A statistically significant relation between test 1 with straps and classification score (coefficient = -0.25; P = 0.008) and test 3 without straps and classification score (coefficient = 1.00; P = 0.032) was found. No further relations emerged between test results and anthropometric data, classification score, and practice's years ( P > 0.05). CONCLUSIONS: These findings demonstrated that straps, as well as ensuring safety and preventing injuries, also improve the WB performance, stabilizing the trunk and implementing upper limb skills, without exposing players to excessive cardiorespiratory and biomechanical stresses.

Bari Shoulder Telemedicine Examination Protocol (B-STEP): A Standard Protocol for Personalized Remote Shoulder Examination.

The COVID-19 pandemic drastically changed many aspects of the traditional functioning of health systems all around the world. In Italy, as reported by the CIO, compared to the previous year, there was a significant reduction in 2020 in overall outpatient activities by up to 75%. These data support the need for telemedicine, which represents a current challenge and can no longer be postponed in the future. This study aims to elaborate on a possible model for remote shoulder examination based on traditional tests to improve the quality of telemedicine in orthopedic and rehabilitation. Between May 2020 and November 2020, ten orthopedic surgeons individually examined six patients with a known shoulder disorder, both in hospital and via webcam according to the previously shared protocol (B-STEP). According to the 10 observers, completing 100% of the ASES score and at least 87.5% of the Constant score is possible. Shoulder ROM and many specific tests are also reproducible via webcam, but with less sensitivity, according to the subjective opinion of observers. The B-STEP is a useful protocol for the standardization of the objective examination of the shoulder via webcam. Further studies are necessary to determine if the B-STEP protocol is useful for diagnosing pathology in unknown patients and evaluating its sensitivity and specificity for each pathology.
