OBJECTIVE: The objective of our article is to review the role of imaging in the diagnosis of various complications of a penile prosthesis (PP). CONCLUSION: Complications of a PP can be categorized into three groups: first, malpositioning, which includes buckling, floppy glans, erosion, migration, and crossover; second, mechanical failure, which includes fracture, aneurysm, and leakage; and, third, infection. Radiography, sonography, CT, and MRI are useful in the detection of these complications and complement each other, with MRI being the most useful imaging modality among them...

Infective endocarditis (IE) is a life-threatening disease, caused by septic vegetations and inflammatory foci on the surface of the endothelium and the valves. Due to its complex and often indecisive presentation the mortality rate is still about 30%. Most frequently bacterial microorganisms entering the bloodstream are the underlying origin of the intracardiac infection. While the disease was primarily restricted to younger patients suffering from rheumatic heart streptococci infections, new at risk categories for Staphylococcus (S...

BACKGROUND AND OBJECTIVES: Diabetes mellitus is an important risk factor for erectile dysfunction (ED). Penile prosthesis implantation surgery is the final solution for diabetic patients with ED, but infections thereof are still a serious risk factor. While some studies suggest that most infections associated with penile prosthesis implantation are associated to high glycated hemoglobin (HbA1c) levels, other research did support such relationship. MATERIALS AND METHODS: The current study assessed retrospectively, the association between HbA1c level and penile prosthesis surgery infection...

Health technology assessments (HTAs) are often difficult to conduct because of the decisive procedures of the HTA algorithm, which are often complex and not easy to apply. Thus, their use is not always convenient or possible for the assessment of technical requests requiring a multidisciplinary approach. This paper aims to address this issue through a multi-criteria analysis focusing on the analytic hierarchy process (AHP). This methodology allows the decision maker to analyse and evaluate different alternatives and monitor their impact on different actors during the decision-making process...

BACKGROUND: Currently, it is challenging to treat massive bone defects of proximal tibia. Although numerous methods are available for reconstruction with epiphysis preservation, limitations in knee function and complications are noted with these methods. Our paper describes our attempt to reconstruct a marked defect in the proximal tibia with an uncemented three-dimensional (3D)-printed prosthesis and to evaluate the prosthesis design and short-term outcomes. CASE PRESENTATION: A 15-year-old boy with metaphyseal osteosarcoma of the tibia underwent intercalary allograft reconstruction following wide tumour resection with epiphysis preservation...

Non-malignant esophageal fistulas have a wide spectrum of clinical and pathological features and it`s important to learn to detect and treat them, due to significant morbidity, mortality and costs. The need for minimally invasive, efficient and also quick procedures is imperative. Esophageal stenting using fully-covered expandable stents has become an increasingly preferred option and addresses to fistulas which arise from 2-3 cm beyond Killian's mouth and up to the gastroesophageal junction. The long-term purpose of the procedure is closure of the fistula and thus healing...

Background and purpose - The Synovasure lateral flow test was developed as a rapid test for the detection or exclusion of periprosthetic joint infection (PJI). 3 studies have reported promising results on its diagnostic value in total joint revision surgery. We aimed to assess the sensitivity and specificity of the Synovasure test to exclude infection in patients undergoing revision surgery for suspected early aseptic loosening of a total hip or knee arthroplasty. Patients and methods - In a prospective study design, 37 patients who underwent revision surgery for suspected early aseptic loosening (< 3 years after primary arthroplasty) were included...

BACKGROUND: Deep prosthetic infection is a potentially devastating complication after total elbow arthroplasty, with an incidence of up to 12%. This study examined the demographics, microbiologic profile, and outcomes of infected total elbow arthroplasty treated with 2-stage revision in a tertiary referral unit. METHODS: We identified 19 consecutive patients (mean age, 65 years) undergoing revision arthroplasty for deep prosthetic infection. All patients underwent a first-stage procedure with removal of implants, débridement, and insertion of an antibiotic-loaded cement spacer, followed by at least 6 weeks of intravenous antibiotics...

When a cranioplasty implant becomes infected, standard operating procedure dictates its removal and the initiation of a long course of antibiotic therapy. However, removing such a prosthesis can have a series of adverse consequences, including delayed cognitive and motor recovery, lack of brain tissue protection, unsightly deformity, and the need for two additional surgical procedures, not to mention the additional costs involved. To maintain the advantages of cranioplasty, we opted for a conservative approach (levofloxacin and rifampicin every 24 hours for 8 weeks) in a 68-year-old woman whose custom-made porous hydroxyapatite implant, fitted following aneurysm clipping, had become infected...

Implants are commonly used as a replacement for damaged tissue. Many implants, such as pacemakers, chronic electrode implants, bone screws, and prosthetic joints, are made of or contain metal. Infections are one of the difficult to treat complications associated with metal implants due to the formation of biofilm, a thick aggregate of extracellular polymeric substances (EPS) produced by the bacteria. In this study, we treated a metal prosthesis infection model using a combination of ciprofloxacin-loaded temperature-sensitive liposomes (TSL) and alternating magnetic fields (AMF)...

Capnocytophaga canimorsus is a commensal organism commonly found in the oral cavity of cats and dogs. Infections with this organism are rare and can affect both immunocompetent and immunocompromised individuals. The authors present a case of C canimorsus causing indolent prosthetic hip joint infection in a healthy 66-year-old woman following a history of being scratched by her pet dog. The patient had an atypical history of chronic, low-grade infection which is unusual, as this organism is more frequently associated with acute presentations and fulminant sepsis...

Opioid analgesics and antibiotics prescribed by dentists is a useful and cost-effective measure when prescribed appropriately. Common dental conditions are best managed by extracting the offending tooth, restoring the tooth with an appropriate filling material, performing root canal therapy, and/or fabricating a prosthesis for the edentulous space. Unnecessary prescription of opioid analgesics and antibiotics to treat dental pain and bacterial infection is a growing public health concern. This article highlights the state of the literature on opioid analgesic and antibiotic prescribing practices in dentistry, the impact of opioid analgesic overdose, and prevention strategies to reduce opioid analgesics and antibiotic overprescription...

The authors present a case of a 69-year-old man with arrhythmogenic right ventricular cardiomyopathy controlled with amiodarone and an infected orthopedic prosthesis requiring treatment with rifampicin. This combination involves a pharmacokinetic drug-drug interaction leading to subtherapeutic drug concentrations of amiodarone and its active metabolite. The long half-life of amiodarone and its active metabolite in combination with the late onset and offset of cytochrome P4503A (CYP3A4) induction by rifampicin makes this a challenging drug-drug interaction to cope with in clinical practice...

Infective endocarditis (IE) is associated with high mortality and morbidity and requires surgical intervention in about half of all patients. Mitral valve repair (MVrep) is reported to achieve better results than mitral valve replacement because the insertion of a prosthesis during active infection is avoided. However, MVrep in active IE is complicated and no definitive guidelines have been compiled. The current study reviews the literature from 2000 to 2016 and summarizes the surgical details of MVrep for IE...

Total nasal reconstruction is a challenging surgical procedure which usually involves a free flap, forehead flap, and cartilage grafts. In certain failure situations where patients do not accept the idea of anaplastology, possibilities become very limited. We report the case of a patient who underwent several reconstruction steps with multiple failures including free and local flaps and cartilage harvests which showed recurrent episodes of necrosis and infection leading to melting and collapse of reconstructed structures...
