BACKGROUND: Glenoid deficiency and erosion (excessive retroversion/inclination) must be corrected in reverse shoulder arthroplasty (RSA) to avoid prosthetic notching or instability and to maximize function, range of motion, and prosthesis longevity. This study reports the results of RSA with an angled, autologous glenoid graft harvested from the humerus (angled BIO-RSA). METHODS: A trapezoidal bone graft, harvested from the humerus and fixed with a long-post baseplate and screws, was used to compensate for residual glenoid bone loss/erosion...

Fungal prosthetic joint infection is a rare complication in total joint arthroplasty. There are no established guidelines for management of these infections. We present a case of a 53-year-old male with a hip joint prosthesis co-infected with Candida tropicalis and Staphylococcus haemolyticus. A two-stage exchange arthroplasty was performed. The patient underwent implant removal, debridement, irrigation with saline solution and application of cement spacer impregnated with vancomycin followed by aggressive antimicrobial treatment in first stage...

Ectopic pregnancies account for 1.5-2% of all pregnancy in the United States. Of these, approximately 10 percent implant in non-tubal locations, including the abdominal cavity, cervix, ovary, interstitial portion of the fallopian tube, broad ligament, the uterine cornua, or within a cesarean section scar. Because these pregnancies tend to present later than typical tubal pregnancies, they have been associated with greater maternal morbidity and mortality. Advances in ultrasound technology have allowed for earlier diagnosis of non-tubal ectopic pregnancies, which in turn has led to the development of novel minimally invasive techniques to manage them...

CONTEXT: Lower urinary tract symptoms (LUTS) are one of the most common and troublesome nonmalignant conditions affecting quality of life in aging men. A spectrum of established medical and surgical options is available to provide relief of bothersome LUTS. Both the adverse events of medication and the morbidity with surgical treatment modalities have to be counterbalanced against efficacy. Novel minimally invasive treatment options aim to be effective, ideally to be performed in an ambulatory setting under local anaesthesia and to offer a more favourable safety profile than existing reference techniques...

The use of mechanical circulatory support has become an increasingly common practice in patients with heart failure, whether used as bridge to transplantation or as destination therapy. The last couple of decades has seen a drastic change in the functioning of the left ventricular assist devices (LVAD), changing from the first generation devices running on pulsatile flow to the current continuous flow devices. Atrial and ventricular arrhythmias are common among heart failure patients, and though the systematic circulation is well supported in patients on mechanical circulatory support, these arrhythmias can still be the cause of detrimental symptoms and lead to potentially fatal outcomes...

Nanostructured hydroxyapatite (HAP) and its nanoparticles are widely used for implantation into the human organism. The biocompatibility of the implants depends very much on the interaction between the implant and the cells regenerating tissue to be connected to the implant. An implant surface electrical charged density plays an important role in these processes. Possible instruments managing the surface electrical potential of HAP are in the focus of this paper. Both theoretical and experimental results evidence that: - the surface electrical charge density of the nanoparticle depends on its size and shape; - the electrical charge density of HAP could be engineered by contact less technique because of deposition of the electrical charge from the external radiation source, surface couples reconstruction...

One-time pad (OTP) is a principle of key generation applied to the stream ciphering method which offers total privacy. The OTP encryption scheme has proved to be unbreakable in theory, but difficult to realize in practical applications. Because OTP encryption specially requires the absolute randomness of the key, its development has suffered from dense constraints. DNA cryptography is a new and promising technology in the field of information security. DNA chromosomes storing capabilities can be used as one-time pad structures with pseudo-random number generation and indexing in order to encrypt the plaintext messages...

Obstructi ve sleep apnoea is an increasingly prevalent clinical condition with significant impact on individuals and public health. Continuous positive airway pressure therapy is the standard treatment, but adherence is limited and alternative treatments are needed. In this context, non-invasive and invasive methods for the electrical stimulation of upper airway dilator muscles have been demonstrated to be effective in selected patients. Areas covered: This review will cover investigations on the clinical effects, safety, and tolerability of non-invasive and invasive electrical stimulation of the upper airway for the management of obstructive sleep apnoea...

Bone tissue engineering (BTE) holds promise for managing the clinical problem of large bone defects. However, clinical adoption of BTE is limited due to limited vascularization of constructs, which could be circumvented by pre-cultivation of osteogenic and endothelial derived cells in natural-based polymer scaffolds. However, until now not many studies compared the effect of mono- and cocultures pre-seeded in collagen before implantation. We utilized a mouse calvarial defect model and compared five groups of collagen scaffolds: a negative control of a collagen scaffold alone, a positive control treated with BMP-7, monocultures of either human osteoblasts (hOBs) or CD34+ cells, and a coculture of hOB and CD34(+) cells...

Currently, the management of urban waste streams in developing countries is not optimized yet, and in many cases these wastes are disposed untreated in open dumps. This fact causes serious environmental and health problems due to the presence of contaminants and pathogens. Frequently, the use of specific low-cost strategies reduces the total amount of wastes. These strategies are mainly associated to the identification, separate collection and composting of specific organic waste streams, such as vegetable and fruit refuses from food markets and urban gardening activities...

Sacral neuromodulation (SNM) is an effective therapy for patients who experience urinary incontinence, idiopathic urinary retention, and fecal incontinence. Although typically a low-risk procedure, rarely, it can be associated with significant hemorrhage. A 61-year-old woman on chronic anticoagulation underwent uncomplicated implantation of SNM for refractory urgency urinary incontinence. Anticoagulation was held on the day of surgery and resumed on postoperative day 1. On postoperative day 2, the patient developed an extensive retroperitoneal hemorrhage...

Immediate implant placement can pose challenges surgically and, ultimately, restoratively. Yet immediate placement has become the standard when adequate bone is present to achieve primary stability and site infection is minimal. To avoid prosthetic complications and ensure the implant is encased in bone after healing, proper planning must consider that implant placement does not necessarily need to follow the trajectory of the root socket. As discussed in this article, maxillary anterior sites have potential issues related to the "triangle of bone" that are not encountered in molar sites and demand different approaches to ensure treatment success...

Type 3 extraction sockets present a unique challenge in that they possess gingival recession indicative of facial hard- and soft-tissue loss. When teeth present with prior disease requiring removal and implant replacement, the treatment strategy incorporates palatal implant positioning as well as proper restorative contour management to compensate for the recession defect, thereby allowing the gingival tissues to heal in the correct 3-dimensional position. This article describes the case of a patient with a nonrestorable maxillary right central incisor with internal resorption...
