Rheumatoid arthritis (RA) is a chronic immune-mediated inflammatory disease of unknown origin. Although it mainly affects joints, it can have extra-articular manifestations, with the lung being one of the most affected organs. The estimated incidence of diffuse interstitial lung disease (ILD) is 4 cases to 4.5 cases/1000 patient-years. The most common forms are usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP; 44–46% and 33–44%, respectively), although there have been reports of cases involving all the histopathologic forms described for the disease. RA-ILD is associated with specific risk factors, such as male sex, older age, smoking, and positive rheumatoid factor (RF) and anti-citrullinated peptide antibody (ACPA) levels. The clinical course of ILD ranges from asymptomatic forms to rapidly progressive disease in a minority of cases. It has been estimated that the risk of death is up to 3-fold higher in patients with RA-ILD than in those without ILD, making RA-ILD the second most common cause of death after cardiovascular disease. Treatment of RA has improved considerably in recent years with the advent of biologics; however, the use of these agents has been restricted in patients with ILD owing to safety concerns. Many doubts continue to surround the treatment of patients with RA-ILD. Therefore, the objective of this review is to examine the current management of affected patients in terms of diagnosis, treatment, and follow-up.

Gout often presents as acute arthritis but may also present with chronic joint inflammation. For the diagnosis of an acute gout attack with its typical symptoms, the differentiation towards a bacterial joint infection is critical and mandatory. The detection of intracellular uric acid crystals in the synovial fluid of affected joints is important for the initial diagnosis of gout. In the case of a chronic course with polyarticular joint involvement, the differentiation from other inflammatory rheumatic diseases such as rheumatoid arthritis (RA) can be challenging. The case presented here is of interest because the patient initially had characteristic clinical symptoms of tophaceous gout including a typical medical history—even though rheumatoid factor and anti-citrullinated protein antibodies (anti-CCP) were positive. The course of the disease and the critical evaluation of all findings also, and most interestingly, including histological results finally suggested a main diagnosis of RA.

Soft tissue sarcoma (STS) is a rare malignancy with a high incidence. Early diagnosis can reduce the rate of amputations and increase survival, however, this is typically delayed. The diagnosis and treatment of smaller lesions have a better prognosis; nonetheless, patients present to physicians when the soft tissue mass is large with obvious signs of red flags. In addition, the symptoms of this disease are highly non-specific and overlap greatly with benign conditions, resulting in a lack of clinical suspicion and low awareness among practitioners and the general public. Thusly, it is entitled as “the loneliest cancer”. This can make an accurate diagnosis difficult, with a great proportion of misdiagnoses leading subsequent inadvertent to incomplete STS excision, affecting the overall prognosis of the disease and devastating consequences in the disease process. A timely and precise diagnosis is essential because half of people with STS progress toward quietly aggressive illness. The purpose of this review is to raise awareness of STSs so that early recognition, accurate work-up, overview of conventional treatment plans, and appropriate referral to a tumor center can be achieved, avoiding whoop situations, and improving patient outcomes. In addition, insight into the advances in immunotherapy, nanotechnology, and artificial intelligence (AI) can lead to STS diagnosis and treatment prognosis.

Following anterior cruciate ligament (ACL) injury of the knee, the functional hop test (an averaging of 4 component hop tests including single-hop, triple-hop, cross-over-hop, and 6-meter-hop) is commonly used by sports medicine physicians, doctors of physical therapy, and athletic trainers in return-to-practice and return-to-play decision making. In this case report, the functional hop test was applied to a 31-year-old recreational basketball player status-post full-tear of the anterior talofibular ligament (ATFL) to examine the applicability of a standardized, efficient, and easy-to-administer functional test in making return-to-play decisions following an ankle injury. The functional hop test was administered 5 times across a treatment course of 11 physical therapy sessions emphasizing pain-free range of motion, baseline strength, weight-bearing loading, and sport-specific training. The functional hop test was found to be a helpful (albeit imperfect) tool for clinical decision-making following an ankle injury. Specifically, improvements in landing skill/confidence of single hop accounted for the greatest gains in total score in the early phase of rehabilitation, while momentum and plyometric skill/control of triple hop accounted for the greatest gains in total score in the later phase of rehabilitation. Modification of the functional hop test to include sub-component tests of strength, endurance, and/or lateral hops are discussed.

Medical attention to uric acid (UA) has been increasing in recent years, mainly because this molecule has been shown to be associated with increased cardiovascular risk, both in the general population and in the hypertensive patients. A growing body of clinical and experimental data supports this view and prompts reconsideration of the role of UA in the development of atherosclerosis and the genesis of cardiovascular disease. It is known that this substance, in certain plasma concentrations, induces increased oxidative stress, a chronic inflammatory state, and a whole series of other modifications that are potentially deleterious at the cardiovascular level leading to hypertension, atherosclerosis, atrial fibrillation (AF), and other metabolic changes such as diabetes, metabolic syndrome, non-alcoholic fatty liver disease and kidney failure. Despite this epidemiologic and mechanistic evidence, the current guidelines from international cardiology scientific societies do not give precise indications in this regard, and some of them only suggest UA evaluation as part of an initial screening of the hypertensive patient. The purpose of this review is to briefly describe the main clinical and epidemiological evidence supporting the role of hyperuricemia as a possible emerging cardiovascular risk factor and to analyze the potential pathophysiological mechanisms through which elevated UA levels may exert a detrimental effect on the cardiovascular system.

Congenital fused/blocked vertebrae are an incidental finding in most cases. It remains asymptomatic unless there is a traumatic event or there is an increased biomechanical load which may be attributed to a task that is not typically performed by the individual. Symptomatic cases can present with several musculoskeletal symptoms including neck pain. Physiotherapy management strategies may help patients recover from the mechanical strains on the cervical neuromuscular structures. The present case is of a 21-year-old male engineering student who was referred for physiotherapy, he presented with complaints of neck pain (non-radiating in nature) for a week. The intensity of the pain had been intermittently increasing/decreasing for about a year and there were about 2–3 episodes in a month for approximately one year. He presented with an X-ray that showed C3–C4 cervical vertebrae synostosis (block vertebrae). The patient was managed using pain education and exercises along with ergonomic advice. Patient-reported pain decreased significantly from the initial visit and he was able to sit for a longer duration and had a considerable improvement in function.

Bone formation is a complex process that occurs throughout life, and is normally limited to the skeletal system. In bone formation, osteoprogenitor cells follow several developmental stages, including differentiation in osteoblasts, proliferation, matrix maturation, and mineralization. The mechanisms involved in the mineralization process of bone, such as in the new bone formation, are extremely complex and have been under intense investigation for many years. Bone formation follows two distinct processes, intramembranous and endochondral ossification; both are regulated by signaling pathways involving numerous genes. Disturbance of these signaling pathways may cause a large spectrum of skeletal diseases characterized by new bone formation and bone growth anomalies. This review will only focus on the key genetic pathways involved in heterotopic bone formation. Wingless/integrated (Wnt), hedgehog (HH), and transforming growth factor beta (TGFβ)/bone morphogenetic protein (BMP) signaling pathways are described and illustrated; their relation with new bone formation is demonstrated through their involvement in bone formation disorders.

Rheumatoid arthritis (RA) is the most common rheumatologic disease characterized by inflammation with a definite relationship with heart disease. Impaired immunity, chronic inflammation, genetic susceptibility, autonomic nervous system (ANS) dysfunction, altered metabolic profile have been blamed for ischemic and non-ischemic heart diseases in RA patients. Medications used in RA treatment can also modify the risk of heart diseases by different mechanisms. Understanding the pathogenesis is essential to prevent early cardiac dysfunction in RA patients. Fundamental cellular and molecular mechanisms of pathogenesis await further elucidation. Disease management is of great importance since the cardiovascular (CV) events are known to be reduced with low disease activity. Discovery of new mechanisms will pave the way for the development of novel treatment modalities. This review highlights the epidemiology, pathogenesis, risk factors, diagnosis and screening methods and management of CV comorbidities in RA patients. Besides impact of RA medications and exercise on CV risk are summarized.
