Wound healing is a complex biological process involving haemostasis, inflammation, cellular proliferation, and remodelling. The use of silver nanoparticles (AgNPs) in wound care has gained significant attention due to their potent antimicrobial, anti-inflammatory, and tissue-regenerating properties. This review provides a comprehensive analysis of the role of AgNPs in wound healing, focusing on their mechanisms of action, efficacy, and clinical applications. The antimicrobial activity of AgNPs helps prevent infections in both acute and chronic wounds, while their ability to modulate inflammation and promote angiogenesis accelerates tissue repair. Various AgNP-based delivery systems, including hydrogels, nanofiber dressings, and composite biomaterials, are explored in the context of wound management, with special emphasis on smart, stimuli-responsive wound dressings. Additionally, clinical evidence supporting the effectiveness of AgNPs in treating chronic, burn, and surgical wounds is reviewed, along with considerations of their safety, cytotoxicity, and regulatory challenges. Although AgNPs present a promising alternative to conventional wound dressings and antibiotics, further research is needed to optimize their formulations and ensure their long-term safety. This review aims to provide insights into current advancements and future perspectives of AgNP-based wound-healing therapies.

Videocapillaroscopy is a simple, non-invasive investigation that allows the “in vivo” study of the nailfold capillaries. This method is inexpensive, easily accepted by patients and the results can be easily interpreted. It is mainly used in patients with Raynaud’s phenomenon and systemic sclerosis, but this examination can also be performed on patients who are suspected of having microcirculation alterations, such as rheumatoid arthritis and psoriatic arthritis. It may aid in the diagnosis, evaluation and prognosis of other rheumatic diseases, besides systemic sclerosis. The aim of this study is to identify the nailfold videocapillaroscopic abnormalities in rheumatoid arthritis and psoriatic arthritis patients and analyze the correlation between their evolution and 12 months of anti-TNF-α therapy. The abnormal capillaroscopic findings comprised widened, dilated or giant capillaries and the distortion of the normal nailfold architecture, avascular areas, hemorrhages and neoangiogenesis. Overall, capillary density, dilated capillaries, giant capillaries, elongated capillaries and angiogenesis significantly improved after 12 months. Moreover, no avascular areas were found after 12 months of anti-TNF treatment.

Interstitial lung disease (ILD) is a severe complication of certain connective tissue diseases (CTDs) such as systemic sclerosis (SSc), mixed connective tissue disease (MCTD), idiopathic inflammatory myopathies (IIM), rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), and it is associated with nailfold videocapillaroscopy (NVC) changes and increased morbidity and mortality rates. Early diagnosis is crucial in order to prevent the progression of ILD, prevent respiratory failure and enhance the patient’s overall quality of life. The most common paraclinical investigations are high-resolution computed tomography (HRCT) and functional respiratory tests such as forced vital capacity (FVC) and the diffusing capacity of the lungs for carbon monoxide (DLCO). The most frequent CTD associated with both ILD and NVC changes is systemic sclerosis. The “late” scleroderma pattern was the most common abnormality identified in NVC results in SSc patients. Other autoimmune diseases were also correlated with ILD and NVC changes, especially when the Raynaud phenomenon was present. Low capillary density was associated with the presence and severity of ILD and a reduction in FVC and DLCO. NVC can also differentiate the capillaroscopic changes in some particular types of ILD, such as the usual interstitial pneumonia (UIP) pattern from the non-specific interstitial pneumonia (NSIP) pattern. Nevertheless, further extensive research is necessary in order to establish the diagnostic value of NVC in CTD-ILD in clinical practice.

Rheumatoid arthritis (RA) is an independent osteoporosis risk factor. Biologic and immunosuppressive treatment, and levels of homocysteine and 25-OH vitamin D may influence the trabecular bone score (TBS) in RA patients. We aimed to compare the effects of biological (b) and conventional synthetic (cs) disease-modifying anti-rheumatic drugs (DMARDs) on TBS in patients with RA and hyperhomocysteinemia (HHcy) or 25-OH vitamin D deficiency. Patients who had tests conducted for trabecular bone score, bone mineral density (BMD), homocysteine (Hcy) and 25-OH vitamin D at an interval of one year and met the inclusion criteria were enrolled in this retrospective study. Sixty-four patients with RA were enrolled and were divided into the following two groups: the first group (34 patients) had received treatment with bDMARDs and the second group (30 patients) had received csDMARDs. BDMARDs and csDMARDs had a positive influence on TBS and BMD. The best results were observed in the Adalimumab group (p = 0.033). Hyperhomocysteinemia and 25-OH vitamin D deficiency led to lower TBS values. Both bDMARDs and csDMARDs positively affected TBS and BMD in RA patients. High homocysteine serum levels or 25-OH vitamin D deficiency had a negative impact on TBS and BMD after 12 months. Our study aims to show the potential benefits of anti-TNF α drugs on TBS. This impact appears to be strongly associated with serum 25-OH vitamin D and homocysteine levels. Anti-TNF drugs may increase bone mineral density and microstructure. As a result, they may minimize the incidence of fractures in RA patients.

Cerebral venous thrombosis (CVT) is a rare type of stroke, with a complex clinical presentation that can make it a diagnostic challenge for the swift initiation of anticoagulation. When a hemorrhagic transformation is added, therapeutic management becomes even more complex. We describe a series of four cases, aged between 23 and 37 years old, with cerebral venous thrombosis. They were admitted to our clinic between 2014 and 2022. All cases presented significant challenges in either diagnostic, therapeutic or etiologic evaluation, at different stages of the disease. Late complications such as epilepsy or depression and other behavioral disorders represent long-term sequelae for the patient. Therefore, through its late complications, CVT is not only an acute disease but a chronic disorder with long-term follow-up requirements. The first case of the series is of a postpartum woman with focal neurological deficit caused by CVT with hemorrhagic transformation that presented multiple thrombotic complications and severe depression. The second case is of a man with extensive cerebral thrombosis who developed bilateral papillary edema under therapeutic anticoagulation treatment. The third case is of a woman with bilateral cavernous sinus thrombosis who later developed depressive disorder and focal seizures. The fourth case is of a pregnant woman in the first trimester presenting with a steep decline in consciousness level secondary to deep cerebral vein thrombosis requiring intensive care and subsequently developing a memory disorder. For a long period of time, due to being underdiagnosed, few things were known about CVT. Nowadays, we have all the tools to diagnose, treat, and follow up cases of CVT.

Objective: To evaluate patients with prosthetic valves who developed infective endocarditis by comparing treatment outcomes in both early- and late-onset IE episodes following prosthetic valve replacement surgery. This study sought to conduct a comprehensive assessment of the efficacy of these methodologies. The insights derived from this assessment can be utilized to enhance the quality of care for individuals with infective endocarditis who have undergone prosthetic valve replacement surgery. Results: During the period of investigation (January 2017–December 2022), 78 patients diagnosed with infective endocarditis (IE) on a prosthetic valve were admitted to the Infectious Diseases Department of the “Dr. Carol Davila” Central Military Emergency University Hospital in Bucharest. In 28 patients (35.8%), the onset of PVE occurred within 12 months of surgery (early onset), whereas in 50 patients (64.2%), the onset occurred more than 12 months after surgery (late onset). The mortality rate was 35.9% (53.6% among the early onset patients and 26% among the late-onset patients). Among patients who received surgical and medical therapy, the mortality rate was 29.6%, whereas among those who received only medical therapy, a 39.2% mortality rate was reported. According to the extracted data, antibiotic therapy was successful in 72.6% of the patients. In contrast, a combination of surgical and drug-based approaches resulted in a cure in 76.1% of patients. The most common etiological agent was Staphylococcus aureus (38.5%), followed by Enterococcus faecalis (26.9%) and Streptococcus mitis (10.3%). The mortality rate of patients infected with S. aureus was 29.2%, indicating the severity of this infectious agent. Conclusions: Prosthetic valve endocarditis (PVE) is a serious condition associated with a high mortality rate both in the short and long term. Regardless of the therapy used, the risk of death remains high.
