Upper respiratory infections are widespread in clinical practice. Antibiotics are frequently used in the management of patients with airways infection. However, antibiotics can induce intestinal and respiratory dysbiosis that, in turn, worsens respiratory symptoms. Moreover, respiratory infections per se can cause dysbiosis. Consequently, probiotics may counterbalance the disturbed microbiota. The current clinical experience evaluated the efficacy and safety of an oral nutraceutical containing a probiotic mixture with Lactobacillus plantarum LP01 (1 billion of living cells), Lactobacillus lactis subspecies cremoris LLC02 (800 million living cells), and Lactobacillus delbrueckii subspecies delbrueckii LDD01 (200 million living cells), in 2928 outpatients with an upper respiratory infection and treated with antibiotics. Patients took one stick/daily for four weeks. Simultaneously, 2877 patients with an upper respiratory infection and treated with antibiotics were recruited as control. This probiotic mixture significantly diminished the presence and the severity of respiratory symptoms at the end of the probiotic course and, more evidently, after a 3-month follow-up. In conclusion, the current clinical experience suggested that this probiotic mixture may be considered an effective and safe therapeutic option in managing patients with an upper respiratory infection and treated with antibiotics.

Otitis media (OM) affects the middle ear and is typically characterized by earache. OM may be classified as acute (AOM) or chronic (COM), based on symptom duration. OM may be clinically suspected, but the diagnosis is usually confirmed by the otoscopy. Antibiotic therapy is frequently used in clinical practice. However, antibiotics often induce intestinal and respiratory dysbiosis associated with some clinical problems. A one-month course of a probiotic mixture (Abincol® containing Lactobacillus plantarum LP01 (1 billion of living cells), Lactobacillus lactis subspecies cremoris LLC02 (800 million living cells), and Lactobacillus delbrueckii LDD01 (200 million living cells), was prescribed in the Group A, and was compared with no addon treatment, such as the Group B. Patients were evaluated at baseline (T0), at the end of antibiotic treatment (T1), at the end of probiotic course (T2), and at the end of 3-month follow-up (T3).

Rhinosinusitis (RS) affects the nose and the paranasal sinus and is characterized by nasal and systemic symptoms. It may be classified as acute or chronic, based on duration. Rhinosinusitis may be clinically suspected, but the diagnosis is usually based on the endoscopy. Antibiotic therapy is frequently used for RS patients in clinical practice. However, antibiotics often induce intestinal dysbiosis associated with some clinical problems and respiratory microbiota impairment. The current clinical experience was conducted in patients with pharyngotonsillitis and treated with antibiotics. A one-month course of a probiotic mixture (Abincol® containing Lactobacillus plantarum LP01 (1 billion of living cells), Lactobacillus lactis subspecies cremoris LLC02 (800 million living cells), and Lactobacillus delbrueckii LDD01 (200 million living cells), was prescribed in the Group A, and was compared with no addon treatment, such as the Group B. Patients were evaluated at baseline (T0), at the end of antibiotic treatment (T1), at the end of probiotic course (T2), and at the end of 3-month follow-up (T3).

Aim of the study: To assess the effects of the available coating methods against methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) biofilm development on titanium implants. Methods: We searched the MEDLINE, Embase, and CENTRAL databases until May 18, 2019, for studies that used animal models of infections to evaluate various titanium implant coating methods to prevent S. aureus infection. Twenty-seven studies were eligible for inclusion in qualitative synthesis. Of those, twenty-three were considered in pair-wise meta-analysis. In addition, subgroup analysis of implant protection strategies relative to uncoated controls was performed, and any adverse events stemming from the coating applications were reported. Quality assessment was performed using SYRCLE’s risk of bias tool for animal studies. Results: Meta-analysis showed that active coating with antibiotics was favoured over uncoated controls (standardised mean differences [SMD] for MRSA and MSSA were – 2.71 [95% CI, − 4.24 to − 1.18], p = 0.0005, and − 2.5 [− 3.79 to − 1.22], p = 0.0001, respectively). Likewise, large effect sizes were demonstrated when a combination of active and conventional non-degradable passive coatings was compared with controls (SMDs for MRSA and MSSA were – 0.62 [95% CI, − 1.15 to − 0.08], p = 0.02, and − 1.93 [95% CI, − 2.87 to − 0.98], p < 0.001, respectively). Discussion/conclusion: As a standalone prevention method, active titanium coating with antibiotics yielded promising results against both MSSA and MRSA. Combinations between active and non-degradable passive coatings, potentially allowing for sustained antimicrobial substance release, provided consistent hardware infection protection. Thus, we recommend that future research efforts focus on combined coating modalities against S. aureus biofilm infections in the presence of titanium implants.

The media play a key role in promoting public health and influencing debate regarding health issues; however, some topics seem to generate a stronger response in the public, and this may be related to how the media construct and deliver their messages. Mass media coverage of COVID-19 epidemic has been exceptional with more than 180,000 articles published each day in 70 languages from March 8 to April 8, 2020. One may well wonder if this massive media attention ever happened in the past and if it has been finally proven to be beneficial or even just appropriate. Surgical site and implant-related infections represent a substantial part of health care-associated infections; with an estimated overall incidence of 6% post-surgical infection, approximately 18 million new surgical site infections are expected each year globally, with 5 to 10% mortality rate and an astounding economic and social cost. In the current mediatic era, orthopaedic surgeons need to refocus some of their time and energies from surgery to communication and constructive research. Only raising mediatic awareness on surgical site and implant-related infections may tune up the volume of silent epidemics to a level that can become audible by governing institutions. © 2020, SICOT aisbl.

Correction: Volume: 971 Pages: 115-116 DOI: 10.1007/5584_2017_13 Published: 2017 WOS:000446017300010 Osteomyelitis is an infectious process in bone that occasionally leads to bone destruction. Traditionally, the surgical treatment procedure is performed in combination with systemic and local antibiotics as a two-stage procedure that uses autograft or allograft bone for filling of the cavitary defect. Bioactive glass (BAG-S53P4) is a bone substitute with proven antibacterial and bone bonding properties. One hundred and sixteen patients who had verified chronic osteomyelitis was treated using BAG-S53P4 as part of the treatment. Most of the patients had previously undergone numerous procedures, sometimes for decades. A register of patient data obtained from 11 centers from Finland, Italy, the Netherlands, Germany, Azerbaijan and Poland was set-up and continuously maintained at Helsinki University Central Hospital. The location of the osteomyelitis was mainly in the tibia followed by the femur and then the calcaneus. The median age of the patients was 48 years (15-87). The patients were either treated according to a one-stage procedure without local antibiotics (85 %) or by a two-stage procedure using antibiotic beads in the first procedure (15 %). The minimum follow-up was 1 year (12-95 months, median 31). The cure rate was 104/116, the total success rate 90 % and most of the patients showed a rapid recovery. The study shows that (BAG-S53P4) can be used in a one-stage procedure in treatment of osteomyelitis with excellent results.

Bowel preparation (BP) for colonoscopy induces significantly changes in gut microbiota and elicit intestinal symptoms. Impaired microbiota causes an intestinal dysbiosis. Consequently, probiotics may counterbalance the disturbed microbiota after BP. The current survey evaluated the efficacy and safety of Abincol®,an oral nutraceuticalcontaining a probiotic mixture with Lactobacillus plantarum LP01 (1 billion of living cells), Lactobacillus lactis subspecies cremoris LLC02 (800 millions of living cells), and Lactobacillus delbrueckii LDD01 (200 millions of living cells), in 2,979 outpatients (1,579 males and 1,400 females, mean age 56 years) undergoing BP. Patients took 1 stick/daily for 4 weeks after colonoscopy. Abincol® significantly diminished the presence and the severity of intestinal symptoms and improved stool form. In conclusion, the current survey suggests that Abincol® may be considered an effective and safe therapeutic option in the management of patients undergoing BP. (www.actabiomedica.it)

Despite the clinical importance of bone metastases, we still know little about their onset and progression and current diagnostic tools lack the sensitivity and specificity required for clear early diagnosis. We therefore need to continue studying the pathogenesis of bone metastatic invasion in order to improve diagnosis. The Wnt pathway has been described as having an important role in bone carcinogenesis and metastatic progression. This study investigated the diagnostic potential of the two main Wnt inhibitors, sclerostin and DKK-1, to improve the detection of osteolytic bone metastases. We measured sclerostin and DKK-1, MMP-2 and MMP-9, the bone resorption marker TRAP5b and the metastatic marker survivin in a control group of healthy patients, in patients with primary tumors and in a group with metastasis. Sclerostin and DKK-1 were clearly high in primary tumor patients and even higher in metastatic patients, compared to controls. The close correlations with metastatic markers and bone resorption markers make sclerostin and DKK-1 promising as new biomarkers in the diagnosis of bone osteolytic metastases.

Endocannabinoids are a class of lipid mediators involved in a wide range of physiological pathways including pain perception, and immunological defences. In particular, the involvement of endocannabinoids in bone metabolism and bone resorption has recently been studied. Moreover, one study on total knee arthroplasty describes the probable role of endocannabinoids in pain perception after surgery. The aim of the present study was to evaluate variations of endocannabinoid concentrations in patients undergoing total hip or total knee arthroplasty before and after surgery. Sera from 23 patients were collected at three different times: before surgery and at two different times during rehabilitation, and endocannabinoids were quantified by HPLC-MS/MS analysis. Mean values of endocannabinoids in presurgical serum samples were: 6.11±0-5 ng/ml for N-palmitoylethanolamide, 1.39±0.08ng/ml for N-stearoylethanolamide, 4.84±0.04 ng/ml for N-oleoylethanolamide, 0.44±0.03ng/ml for N-arachidonoylethanolamide, 0.84±0.05ng/ml for N-linoleoylethanoIamide, 0.17±0.01ng/ml for N-α-linolenoylethanolamide. Statistical analysis showed a significant decrease of all the endocannabinoids after surgery, while there were no remarkable differences between total hip and total knee arthroplasties or between genders. Moreover, the results show no significant correlation between endocannabinoid concentrations and C-reactive protein and Erythrocyte sedimentation rate. The present study shows for the first time a specific and univocal behaviour of six endocannabinoids and iV-acylethanolamides in orthopaedic surgery, suggesting the endocannabinoid system as a possible pharmacological target for presurgical therapeutics.
