Tenodesis in Flail Foot: A New Surgical Technique.

Flail foot is a condition characterized by a significant weakness in ankle dorsiflexion, resulting in limited or no active mobility in the ankle. To address this issue, we described a novel approach called tenodesis, which has been developed for ankle joint stabilization. This technique utilizes the patient's tendons to minimize potential complications.

Functional outcomes may vary over time after patellar tendon and knee intra-articular heterotopic ossification excision: A case report.

Introduction: Heterotopic ossification (HO) is the formation of mature bone in soft tissue, often occurring after fractures and trauma. Patients with HO experience pain, joint stiffness, and other complications. Treatment aims to improve function; surgical procedures have succeeded in 83.

Sargassum glaucescens Extract/Marine-Derived Collagen Blend Sponge and Their Properties for Wound Healing.

Burn wounds are challenging to treat due to considerable tissue damage and fluid loss. Creating wound dressings from natural and biological materials makes it possible to treat wounds and promote rapid epithelialization to speed healing and restore skin function. As a result, the ability of a collagen scaffold (Col) made from rainbow trout (Oncorhynchus mykiss) and putative bioactive phytochemical components from a Sargassum glaucescens (S.

Time Reveals the Truth! What Treatments for COVID-19 Were Quickly Abandoned, and Which Methods, Contrary to Popular Belief, Are Still Flourishing?

During the early days of the COVID-19 pandemic, low dose radiation therapy (LDRT) was proposed as a potentially effective treatment method. To minimize potential toxicity, the initial treatment approach involved a few mGy of adapting radiation followed by a single 250 mGy whole lung challenging dose. However, antiviral drugs were also introduced as a promising treatment option, which were thought to have the potential to revolutionize the management of the crisis.

A Half-century Experience of Running Journal Clubs and applying Interactive Teaching-learning Methods at Orthopedic Department of Tehran University of Medical Sciences.

Journal club is crucial in medical professions education, especially residency training. Critical evaluation allows learners to read, understand, and apply the evidence to bridge the gap between research and practice. Academic members of the Tehran University of Medical Sciences (TUMS) Orthopedic Department have held about 2,300 weekly sessions for around 50 years, even in times of crises, to review the latest publications in orthopedics and sometimes linked their journal clubs to hospitalized cases.

Mobile bearing total knee arthroplasty does not lead to better joint awareness compared to fixed bearing design: A systematic review and meta-analysis.

Purpose: Mobile-bearing total knee arthroplasty (MB-TKA) and fixed-bearing (FB) TKA are both widely used, with MB-TKA theoretically offering better functional outcomes due to its natural kinematics. This systematic review and meta-analysis aimed to compare joint awareness between MB-TKA and FB-TKA, as measured by Forgotten Joint Score-12 (FJS-12), to provide insights into patient-perceived outcomes.

Methods: A comprehensive literature search was conducted across major databases following PRISMA guidelines, without date or language restrictions.

Evaluation the level of vitamin D and its relationship with clinical symptoms in patients with COVID-19 referred to the medical center in Bam city.

Background: Vitamin D is a steroid hormone that protects against viral infections by influencing innate and adaptive immune responses. The effectiveness of vitamin D3 supplementation in COVID-19 is unknown. The study's goal was to elucidate the relationship between blood vitamin D levels and COVID-19 clinical outcomes by examining the effect of a single high dose of vitamin D3 on the length of hospital stay in COVID-19 patients.

Evaluation of Monascus purpureus fermentation in dairy sludge-based medium for enhanced production of vibrant red pigment with minimal citrinin content.

This study aimed to explore the production of red pigment from Monascus purpureus in waste culture medium and its potential health benefits. Subsequently, the M. purpureus cultivated in a medium containing dairy sludge as waste, the extracted pigment was purified, and subjected to various analyses, including liquid chromatography mass spectrometry (LCMS) and nuclear magnetic resonance (NMR) to verify its purity, high-pressure liquid chromatography (HPLC) to measure the citrinin levels, microbial, and antioxidant activity.

The impact of epithelial-mesenchymal transition (EMT) induced by metabolic processes and intracellular signaling pathways on chemo-resistance, metastasis, and recurrence in solid tumors.

The intricate cellular process, known as the epithelial-mesenchymal transition (EMT), significantly influences solid tumors development. Changes in cell shape, metabolism, and gene expression linked to EMT facilitate tumor cell invasion, metastasis, drug resistance, and recurrence. So, a better understanding of the intricate processes underlying EMT and its role in tumor growth may lead to the development of novel therapeutic approaches for the treatment of solid tumors.

Does body mass index (BMI) significantly influence aseptic loosening in primary total knee arthroplasty? Insights from a long-term retrospective cohort study.

Background: Total knee arthroplasty (TKA) offers substantially improved function for patients with severe osteoarthritis, but long-term success can be overshadowed by aseptic loosening, a complication with a multifactorial etiology. This study aims to investigate the association between BMI and the rate of aseptic loosening and other complications in patients undergoing primary TKA.

Methods: This retrospective cohort study examined 354 TKA patients, evenly categorized by BMI (≤ 30 kg/m² and > 30 kg/m²).

Anxiolytic Effect of Jasmine Aromatherapy in Pediatric Dental Procedures: A Single-Blinded Randomized Placebo-Controlled Trial.

The aim of the present investigation was to evaluate the possible anxiolytic effect of jasmine aromatherapy in pediatric dental procedures. A parallel randomized single-blinded placebo-controlled clinical trial was designed and conducted from February 19 until April 19, 2020, on children aged 7 to 12 years-old requiring class 1 restorative treatment of primary or permanent tooth with infiltration anesthesia. Interventions were defined as 15 minutes of aromatherapy using 2mL of jasmine extract for the intervention group, and with water for the control group.

Simultaneous Bilateral Total hip Arthroplasty in Patients With Juvenile Idiopathic Arthritis via Direct Anterior Approach: Long-Term Outcomes.

Background: Juvenile idiopathic arthritis (JIA) often results in significant bilateral hip damage, necessitating total hip arthroplasty (THA). Simultaneous bilateral THA offers potential advantages, particularly when executed via the Direct Anterior Approach (DAA). This study aims to assess the functional, radiological, and patient-reported outcomes, along with the complications of bilateral uncemented THA performed via DAA in patients with JIA.
