Aspergillus spp. osteoarticular infections: an updated systematic review on the diagnosis, treatment and outcomes of 186 confirmed cases.

Aspergillus spp. osteoarticular infections are destructive opportunistic infections, while there is no clear consensus on their management. The purpose of this review is to investigate the current literature regarding Aspergillus spp. osteoarticular infections. An electronic search of the PubMed and Scopus databases was conducted considering studies that assessed osteoarticular infections from Aspergillus spp. We included only studies with biopsy proven documentation of positive cultures or histological findings for Aspergillus spp., and those with essential information for each case such as the anatomical location of the infection, the type of treatment (conservative, surgical, combination), the antifungal therapy, and the outcome. Overall, 148 studies from 1965 to 2021 including 186 patients were included in the review. One hundred and seven (57.5%) patients underwent surgical debridement in addition to antifungal therapy, while 79 (42.7%) patients were treated only conservatively. Complete infection resolution was reported in 107 (57.5%) patients, while partial resolution in 29 (15.5%) patients. Surgical debridement resulted in higher complete infection resolution rate compared to only antifungal therapy (70.0% vs. 40.5%, P < 0.001), while complete resolution rate was similar for antifungal monotherapy and combination/sequential therapy (58.3% vs. 54.5%; P = 0.76). Last, complete resolution rate was also similar for monotherapy with amphotericin B (58.1%) and voriconazole (58.6%; P = 0.95). The results of this study indicate that antifungal monotherapy has similar efficacy with combination/sequential therapy, while voriconazole has similar efficacy with amphotericin B. Moreover, surgical debridement of the infected focus results in better outcomes in terms of infection eradication compared to conservative treatment. LAY SUMMARY: Antifungal monotherapy has similar efficacy with combination/sequential therapy, and voriconazole has similar efficacy with amphotericin B for the treatment of Aspergillus spp. osteoarticular infections, while surgical debridement of the infected focus improves the infection eradication rate.

A randomized, single-blinded, vehicle-controlled study of a topical active blend in the treatment of androgenetic alopecia.

Αndrogenetic alopecia (AGA) is the most common hair disorder, affecting approximately 50% of men and women. A topical lotion that contains two patented formulas (Redensyl and Sepicontrol A5), has been introduced as an alternative approach to standard therapies for AGA. Forty-four patients with AGA were randomized either to apply the active lotion or the vehicle, twice daily for 24 weeks. Subjects were evaluated at 0, 12, and 24 weeks by clinical examination, photographic documentation, quality of life evaluation (DLQI), and trichogram (anagen-to-telogen ratio). Forty-one patients, 18 males and 23 females, completed the study. Among patients receiving active treatment (n = 26), 7.7% had great improvement, 73.1% had moderate improvement, and 19.2% remained stable. The median self-assessment score increased from 4 at baseline to 6 at 24 weeks (P < .001), while the DLQI improved from 4 to 3, respectively (P < .001). The median anagen-to-telogen ratio increased from 2.25 to 4.00 to 6.02 at weeks 0, 12, and 24, respectively. No significant adverse events were reported. This new topical active blend is effective in the treatment of AGA, with high degree of patients' satisfaction, improvement of quality of life, and an excellent safety profile. Thus, it may represent a useful alternative therapeutic approach for AGA.

Electroacupuncture for the treatment of supraspinatus calcific tendonitis.

BACKGROUND: Conservative treatment of calcific tendonitis includes rest, medications, and physical therapy. Several physiotherapy interventions such as shockwave therapy are commonly used. The aim of this study was to investigate the efficacy of an electrotherapy method called electroacupuncture, in the treatment of calcific tendonitis. METHODS: 40 patients with calcific tendonitis were randomly divided to receive either a combination of medications and electroacupuncture, or just a course of medications. Evaluated outcomes included pain using the visual analog scale, shoulder range of motion with the use of goniometer, and quality of life along with functional status using the Instrumental Activities of Daily Living Scale (IAOLDS) and the Beck Depression Inventory (BDI). Radiological evaluation for the progression of the calcific deposits was also performed. All these evaluations were performed before and at the end of treatment. A final interview with the patients regarding any recurrent episodes was performed 18-24 months after the end of treatment. RESULTS: The intervention group showed greater improvement in pain intensity (2.8 points), range of motion (forward flexion, +30; abduction +29) when compared with the control group (for all, P < .05) while there was no statistically significant difference regarding the quality of life (IOLDS +0.2; BDI 0). Radiological evaluation demonstrated total or nearly total absorption of calcific deposits in 15 patients of the intervention group and in 8 patients of the control group. CONCLUSION: The successful clinical results of electroacupuncture and the regression of calcific depositions after treatment showed that electroacupuncture may have a role as a treatment modality in calcific tendonitis.

Antithrombotic efficacy of direct oral anticoagulants on patency rate following microsurgical anastomosis in crushed rat arteries.

BACKGROUND: During the last decade direct oral anticoagulants (DOAC) have been established in various fields of medicine.Their use in microsurgery has not been evaluated yet though. This study aims to evaluate their efficacy in microsurgery and additionally compare them with a well established antithrombotic agent. MATERIALS AND METHODS: The right femoral artery of 101 rats divided into 4 groups, was crushed and anastomosed. Group A (20 rats) received placebo therapy (1 ml NaCl 0.9%, orally), while Group B (27 rats), Group C (27 rats) and Group D (27 rats) received rivaroxaban (3 mg/kg, orally), dabigatran (30 mg/kg, orally) and enoxaparin (30 mg/kg, subcutaneously) respectively. All drugs were administered 3 h preoperatively and once daily for the following postoperative days until the sacrifice of the animals. Patency was evaluated at 1st, 7th and 20th postoperative day. Following patency evaluation the rats were sacrificed and the vessels were harvested for histological examination. RESULTS: None of the rats died postoperatively. Patency rates of rivaroxaban group (78%), dabigatran group (70%) and enoxaparin group (63%) were statistically similar, but significantly higher than the placebo-treated control group (p < 0.05). Cells with morphologic features of endothelial cells were evident 7 days after the injury. CONCLUSION: The results of this study demonstrate the following: (1) rivaroxaban and dabigatran through inhibition of thrombus formation significantly enhanced the patency rate compared to placebo treatment (2) the antithrombotic efficacy of rivaroxaban and dabigatran in compromised microvessels was similar to that of enoxaparin, the most widely used antithrombotic agent.

The role of new oral anticoagulants in orthopaedics: an update of recent evidence.

Rivaroxaban, dabigatran, apixaban and edoxaban are the four available new oral anticoagulants (NOAC) which are currently approved for venous thromboembolism prophylaxis after total hip and knee replacement. Large phase 3 and phase 4 studies comparing NOAC with low molecular weight heparins have shown similar results regarding the efficacy and safety of these two categories of anticoagulants. Management of bleeding complications is a matter of great significance. Three reversal agents have been developed: idarucizumab, andexanet alfa and ciraparantag. Idarucizumab is now commercially available. Regarding the perioperative management of NOAC, two main scientific groups have published their own recommendations. The European Heart Rhythm Association recommends 48-h period of stoppage preoperatively for factor Xa inhibitors and at least 3 or 4 days for dabigatran, while the French Study Group on Thrombosis and Haemostasis recommends 5-day discontinuation for all NOAC. Conventional clot tests can only be used as rough indicators for laboratory assessment of the activity of NOAC. Specific laboratory tests have been developed for more accurate measurements of NOAC blood levels, including a dilute thrombin time test (Hemoclot test) and the ecarin clot test for dabigatran and chromogenic anti-factor Xa assays for direct factor Xa inhibitors. Due to the beneficial properties of NOAC, these drugs are gaining ground in daily orthopaedic practice, and many studies are being conducted in order to extend the indications of these anticoagulants agents.
