RESUMO

Background The transition from paper charts to electronic medical records (EMRs) has resulted in greater efficiency and reduced medical errors. This study aimed to examine the perception of patients and orthopedic residents regarding computer use during the clinic visit. Methodology This study utilized a cross-sectional cluster design. Orthopedic resident physicians were given a one-time general pre-visit survey. Additional surveys were given to patients and resident physicians post-visit. Surveys included questions that assessed satisfaction and the perceived impact of computer usage on doctor-patient interactions. Logistic generalized estimating equations were run to determine if there was an association between patient response and clinician assessment, adjusting for repeated measures within clinicians. Results A total of 80 patients and 15 residents completed the surveys. Results from the physician pre-visit survey showed that more residents perceived the computer as having a "negative" (47%) than "positive" (26%) effect on their relationship with patients. According to the post-visit analysis, patients perceived the residents' use of the EMR as having an overall positive effect on their ability to establish a personal connection and having a positive effect on their ability to give them attention. Conclusions Overall, there was little correlation between patient and resident perception of the computer's effect on their relationship. Patients generally perceived the computer as having a positive effect on their interaction with the residents even when residents had a negative perception of the computer's effect on their interaction.

RESUMO

Chronic obstructive pulmonary disease (COPD) is a major medical problem and the world's third leading cause of death. COPD is a chronic disease with heterogeneous clinical symptoms, disease progression, and treatment responses. Besides pulmonary symptomatology, the common systemic clinical manifestations are cachexia, muscle weakness, and widespread comorbidities such as cardiovascular diseases, diabetes, osteoporosis, and infections. The adverse effects of pharmaceutical therapies contribute to the difficulty of health risk assessment and management of COPD patients. This review shows how skeletal muscle dysfunction and metabolic abnormalities contribute significantly to COPD patients' symptoms, functional activities, quality of life, and overall disease outcomes. Based on the clinical evidence of L-carnitine and derivatives as metabolic and muscle bioenergetic enhancers, we propose broader research and implementation of this nutraceutical agent as an effective, inexpensive, and safe adjuvant therapeutic for the long-term management of COPD patients. Moreover, we believe the management of COPD as a chronic disease should be shifted from symptomatic reactive pharmaceutical intervention to more constructive and non-toxic approaches using a single or combination of natural and nutritional agents with potential muscle metabolic enhancing and immunomodulating activities to achieve a better overall outcome for the patients in terms of morbidity, mortality, and medical cost-reduction.

RESUMO

BACKGROUND/AIM: Radiation cystitis is a frequent complication that can occur after therapeutic irradiation of pelvic cancers. The current treatment for this condition is complex and often ineffective. CASE REPORT: We present a clinical case of a 54-year-old patient diagnosed with small cell cervical cancer FIGO stage IIIC who developed grade 2-3 radiation cystitis following post-operational chemoradiation therapy. The patient exhibited increased urinary urgency and frequency, dysuria, and low abdominal pain, which failed to respond to acupuncture and corticosteroid treatments. A course of Ich Nieu Khang phytotherapy tablets, resulted in significant improvement of symptoms within 24 hours of initiation. The symptoms resolved completely within 10 days, and ultrasonography documented a marked decrease in bladder wall thickening and improved bladder evacuation function. The phytotherapy was well-tolerated, and no side-effects were observed during the 60-day treatment period. CONCLUSION: These findings suggest that phytotherapy may be viable for managing radiation cystitis. However, further controlled clinical trials are needed to confirm the efficacy of Ich Nieu Khang and promote its broader clinical applications.

RESUMO

BACKGROUND/AIM: Plantar warts are cutaneous lesions on the plantar aspect of the foot caused by the infection of keratinocytes with the human papillomavirus (HPV). The severity and magnitude of warts can vary, but they cause pain and discomfort for all age groups. The treatment for plantar warts remains a continuing challenge. The purpose of this research was to compare the efficacy and safety of naturally derived Nowarta110 topical formula versus a matching placebo in treating plantar warts. PATIENTS AND METHODS: The study is a randomized, double-blind, parallel assignment control interventional phase I/II clinical trial. This study included 54 patients with plantar warts. Patients were randomized to two groups: the placebo group, which included 26 patients treated with a matching placebo and the Nowarta110 group, which included 28 patients who received topical Nowarta110. The diagnosis of plantar warts was made by clinical examination. The treatment's efficacy and safety were assessed every week and after 6 weeks from the initiation of the intervention. RESULTS: In the Nowata110 group, 18 patients (64.3%) were completely cleared of their warts, and 10 patients (35.7%) partially responded to the therapy with a 20% to 80% decrease in warts dimensions. In the placebo group, only 2 patients (7.7%) were completely cleared of their warts, and 3 patients (11.5%) partially responded to the intervention with a 10% to 35% decrease in warts dimensions. The difference was highly significant between the two groups. There was 1 event with minor pain as a side effect in the Nowarta110 group and 9 events of non-serious local side effects in the placebo group, which included 2 patients who dropped out. CONCLUSION: Topical Nowarta110 is a safe, well-tolerated, and highly effective therapeutic modality in treating refractory and recurrent plantar warts. The breakthrough findings of the study encourage further extensive clinical trials to fully explore the prospect of Nowarta110 in managing all types of warts and HPV-related diseases.

RESUMO

Hyperlipidemia impacts millions of people globally and has been the major risk factor for developing atherosclerosis and cardiovascular disease. Interestingly, hyperlipidemic subjects exhibit increased incidence of rotator cuff tendon injury (RCTI) and disorganization of tendon matrix. Low-density lipoproteins (LDL) and its oxidized form (ox-LDL) play a crucial role in hyperlipidemia-driven pro-inflammatory responses in multiple tissues including the tendon. The signaling of oxLDL upregulates the inflammatory cytokines, chemokines, adhesion molecules, and the activation of monocytes/macrophages/resident tendon cells and matrix metalloproteinases impairing the tendon homeostasis resulting in the alteration of extracellular matrix. In addition, the hyperlipidemia-driven immune response and subsequent oxidative stress promote degenerative responses in the tendon tissue. However, the pathological mechanisms underlying the occurrence of RCTI in hyperlipidemia and the effect of ox-LDL in tendon matrix are currently unknown. The present review focuses on the implications and perspectives of LDL/oxLDL on the increased incidence of RCTI.

RESUMO

One of the major hallmarks of many cancer cells is dedifferentiated cells (immature cells) with little or no resemblance to normal cells. Besides the poor differentiation, malignant cells also have important features such as aggressiveness and resistance to different therapeutics. Differentiation potentiators hold great promise for cancer treatment. Dimethyl sulfoxide (DMSO) is a well-characterized pharmaceutical solvent. It is used as a component of numerous cancer therapeutic approaches, including cancer treatment and several approved cancer immune therapeutics such as Car-T cell therapy and the FDA-approved drug Mekinist (trametinib DMSO) for melanoma treatment. It is also biologically recognized as a pharmaceutical solvent and cryoprotectant. In the current literature, there are no mentions of DMSO's possible ability to potentiate therapeutic activity as a component of these cancer treatments. This review aimed to summarize scientific evidence and substantiate the concept that DMSO can contribute positively to the overall efficacy of cancer treatment as an adjuvant that is safe, inexpensive, and an effective differentiation-inducing therapeutic agent.

RESUMO

BACKGROUND: An often-overlooked item that could cause contamination in the operating suite are the towels used for hand drying following surgical scrub. The purpose of this current study was to determine if there was a difference in the particulate count from different hand drying methods following surgical hand preparation. METHODS: Three simulated hand drying groups were established: disposable sterilized surgical towels, reusable sterilized surgical towels, and a waterless alcohol-based dry rub. Particle size measurements of 0.3 µm, 5.0 µm, and 10.0 µm were collected at time zero and repeated every minute for 5 minutes for a total of 10 trials each. RESULTS: Both the reusable and disposable towels produced significantly more particle matter in all size groups compared to the alcohol scrub control group. A comparison analysis and ANOVA testing demonstrated that alcohol dry scrub produced significantly fewer particles compared to both the disposable blue towels (P < .01) and the reusable green towels (P < 0.01). Disposable towels produced significantly more particles in the 0.3 µm count compared to reusable towels (P < .05). CONCLUSIONS: An alcohol-based dry rub without using a towel yielded the lowest amount of particulate formation in this experimental model, while reusable surgical towels produced the highest number of particles. LEVEL OF EVIDENCE: Level II Experimental Study.

RESUMO

Shoulder tendon injuries are the common musculoskeletal disorder resulting in significant pain and disability. These injuries are characterized by chronic inflammation and tissue degeneration. Tendon pathology exhibits poor innate healing ability, enhanced inflammation, disorganized collagen fibers, calcification, and scar tissue formation affecting the normal healing process. Extracellular vesicle, especially exosomes, treatment has been emerging as a potential regenerative strategy improving the outcomes and biomechanical properties, accelerating tenocyte proliferation and migration, reducing inflammation, and facilitating the healing at tendon-bone interface. In this article, we critically reviewed the potential role of exosomes in tendon regeneration and their applications to accelerate the healing response following injury. In addition, the article provides novel insights on the concept of "Smart Exosomes" by programming/manipulating the secretome contents and functions of exosomes in the management of shoulder tendon injury. Impact statement The exosomes pose tremendous regenerative capacity in otherwise inherently poor tendon healing following shoulder injury. Understanding the exosome biology in the context of tendon injury offers immense opportunities for developing novel regenerative approaches. Herein, we focus on the novel concept of "Smart Exosomes" by programming the regenerative properties of exosomes as a next-generation management strategy for shoulder tendon injury.

RESUMO

Accurately measuring the length and diameter of the hamstring tendon autograft preoperatively is important for planning anterior cruciate ligament (ACL) reconstructive surgery. The purpose of this study was to assess the reliability of three-dimensional computed tomography (3D CT) scanning technique to produce the actual measurement of the gracilis and semitendinosus (GT and ST, respectively) tendon grafts' length and diameter for surgery. Ninety patients were scheduled for ACL reconstruction with hamstring autograft. Before the surgery, patients were examined under the multidetector row CT scanner and the ST and GT tendons were qualitatively measured by a volume-rendering technique. The length of ST and GT was measured with 3D CT compared with the length of the harvested ST and GT. The cross-sectional area (CSA) of ST and GT measured with 3D CT compared with the ST and GT graft diameter. Tendon size measured preoperatively and during surgery were statistically compared and correlated. The GT tendons length and cross-sectional area measured during surgery was both shorter and smaller compared with the ST tendon. GT and ST tendon length were correlated to patients' body index such as the height and weight (p < 0.05). However, the correlation levels were low to medium (r = 0.23-0.49). There was strong correlation between the lengths of GT (r = 0.76; p < 0.001) and ST (r = 0.87; p < 0.001) measured with the 3D CT and tendon length at surgery. There was a moderate correlation between graft diameter measured at surgery and 3D CT cross-sectional area (r = 0.31; p < 0.05). A multidetector row CT scanner can determine the ST and GT tendons' length and diameter. These measurements can be used for preoperative planning to help determine the surgical method and counsel patients on appropriate graft choices prior to surgery.

RESUMO

Tibial deficiency (also known as tibial hemimelia) is a rare condition with variable presentation. A 2-month-old patient presented with absent bilateral tibias. When the patient was 1 year, a novel reconstructive surgery was done. A bilateral fibular resection with pedicled calcaneus transfer was done, allowing for transfer of the calcaneus along with the overlying glabrous skin and soft tissues to the end of the femur. The patient was permitted to weight-bear after the 4-week postoperative follow-up. At the six-month follow-up, the patient was able to pull to stand and walk with assistance without any reports of pain.

RESUMO

PURPOSE: To review the current literature to determine which injection technique and needle portal placement provide the greatest accuracy for intra-articular access to the knee. METHODS: This study followed Preferred Reporting Items and Systematic Reviews and Meta-Analyses guidelines. A comprehensive literature search was conducted in March 2020 and repeated in May 2020 using electronic databases PubMed, MEDLINE, and the Cochrane Library. Data on the accuracy of intra-articular knee injection (successful injections/total number of injections) were collected. Only Level I studies were included. Study design, demographic variables, needle sizes, and method of validating accuracy were recorded. The Jadad score was used to assess methodologic quality, and a risk-of-bias assessment was performed. RESULTS: A total of 12 Level I human studies (1431 patients, 1315 knees) were included in this review. Seven of the studies did a direct comparison between ultrasound-guided and blind knee injections. Ultrasound-guided injections were more accurate compared with blinded knee injections in every study. The most accurate anatomical approach was an isometric quadricep contraction method with the superolateral approach. CONCLUSIONS: This study showed that ultrasound-guided knee injections were more accurate across every anatomical needle injection site compared with blind injections. Injections made by a blind/anatomically guided method had inconsistent accuracy rates that seemed highly dependent on the portal of entry. LEVEL OF EVIDENCE: Level I, systematic review of Level I studies.

RESUMO

The use of biologically based therapies is becoming a popular less-invasive therapy for relieving pain and promoting tissue regeneration. The most commonly used biologics are autologous adipose-derived products, bone marrow aspirations, and platelet-rich plasma (PRP). Birth tissue is a common allogenic source of biologics, including umbilical cord, placental membranes, and amniotic fluid. Injected biologics, depending on the indication and how they are processed, formulated, delivered, and promoted, can be subject to different regulatory pathways. The aim of this review is to provide an overview of these products and procedures and educate the musculoskeletal community about the relevant current Food and Drug Administration (FDA) regulations.

RESUMO

Wound healing has been intensely studied to expedite recovery times and reduce scarring. However, current technologies fail to achieve regenerative capabilities, leaving wounds with scarring and lack of skin accessories. The recent emergence of nanotechnology has provided a new clinical modality of zinc nanoparticles in wound care. This present study investigated Zinc Sulfide nanoparticles (ZnS-NP) on wound healing in vitro with 2D and 3D models and in vivo with rat full-thickness wound model. ZnS-NP inhibited fetal bovine serum-stimulated rat skin fibroblast cell proliferation, altered cytoskeletal organization, and reduced collagen synthesis as well as contractile activity. ZnS-NP regulated redox homeostatsis and promoted fibroblast viability in 3D hypoxia conditions. In the rat full-thickness wound model, ZnS-NP reduced wound contraction, enhanced re-epithelization, and promoted skin appendage formation. The biological activities of ZnS-NPs determined in our current study may suggest promising practical applications for topical or systemic treatment for wound repair.

RESUMO

The United States Food and Drug Administration (FDA) is responsible for protecting and promoting public health through rules and regulations. Over the past few years, the field of regenerative medicine and cell therapy have garnered significant interest, and this evolving new biology is changing fast and challenging regulatory bodies. The FDA has published a series of guidance documents outlining steps to protect consumers against potentially dangerous and unproven treatments. The agency has offered a grace period for "stem cell clinics" until November 2020 to come into compliance by obtaining Investigational New Drug applications and working to secure premarket approval of their products. With the documentation of hundreds of "stem cell clinics," the FDA needs to enforce the adherence to their outlined standards to protect patients. The aim of this review was to provide an overview of these FDA regulations and some current issues within the industry. The purpose is to educate and inform the musculoskeletal community about the current government regulations of this new expanding biology. LEVEL OF EVIDENCE: Level V, expert opinion.
