A case of endogenous endophthalmitis caused by Escherichia coli septicemia.

Endogenous endophthalmitis is a severe sight-threatening condition that requires urgent intervention. It is a rare complication of septicemia. We herein report a case of left eye endogenous endophthalmitis with uncontrolled type 2 diabetes mellitus with pyelonephritis associated with septicemia.

Extensive Metallosis in a Primary Knee Arthroplasty as a Result of Polyethylene Wear: Is It Avoidable?

Metallosis is known to occur in metal-on-metal arthroplasty and has been of concern to orthopaedic surgeons worldwide. It is a rare, late complication of total knee arthroplasty (TKA), in which metal-on-metal contact leads to metal debris deposition in the surrounding tissue. Reasons for metal-on-metal contact could range from wear of the polyethylene insert to abnormal joint biomechanics.

Impact of surgical timing and type of operative procedure on outcomes in periprosthetic hip fractures: an observational study at an NHS trust centre in the UK.

Purpose: There is a global trend of increased periprosthetic fractures due to the growing number of arthroplasty procedures. The present study assessed the impact of factors such as time to surgery and type of surgery on the outcomes, which have been seldom evaluated for periprosthetic fractures.

Methods: An observational study was conducted on consecutive 87 patients within an NHS district hospital trust in the UK.

Use of a Trephine to Extract a Fractured Corail Femoral Stem During Revision Total Hip Arthroplasty: Tips From Our Case Report.

Despite the significant advancements in the field of total hip arthroplasty (THA) and prosthesis designs, fracture of the modular femoral stem after THA can occur rarely and needs attention. Orthopaedic surgeons face a daunting task when it comes to the removal of a broken stem. The use of a trephine reamer has been evaluated for extracting the distal femoral stem, and this case report tries to address some key tips for the same.

Fluid interfaces laden by force dipoles: towards active matter-driven microfluidic flows.

In recent years, nonlinear microfluidics in combination with lab-on-a-chip devices has opened a new avenue for chemical and biomedical applications such as droplet formation and cell sorting. In this article, we integrate ideas from active matter into a microfluidic setting, where two fluid layers with identical densities but different viscosities flow through a microfluidic channel. Most importantly, the fluid interface is laden with active particles that act with dipolar forces on the adjacent fluids and thereby generate flows.

Non-Union And Resorption Of Extended Trochanteric Osteotomy And Management Using Modular Tapered Stem In Patient With Extensive Surgical History.

Extended trochanteric osteotomy is an invaluable technique for enhancing femoral exposure during revision total hip arthroplasty. Complications are rarely reported but may include non-union. Even rarer is the incidence of extended trochanteric osteotomy resorption.

Fracture Of An Exeter™ V40™ Stem Through The Insertion Guide Hole And Revision Using Cement-In-Cement Technique.

Fracture of the Exeter™ V40™ stem is uncommonly reported in the literature. The cement-in-cement femoral revision is a described technique for revising well-cemented femoral components during revision hip arthroplasty. We present our experience using this technique in managing a fractured Exeter™ V40™ stem.

Instability of a liquid sheet with viscosity contrast in inertial microfluidics.

Flows at moderate Reynolds numbers in inertial microfluidics enable high throughput and inertial focusing of particles and cells with relevance in biomedical applications. In the present work, we consider a viscosity-stratified three-layer flow in the inertial regime. We investigate the interfacial instability of a liquid sheet surrounded by a density-matched but more viscous fluid in a channel flow.

Medium term outcome of Lancaster cortical window technique for extraction of femoral stem in revision hip arthroplasty.

Background: The extraction of a femoral stem during the revision hip arthroplasty can be a daunting task and can lead to catastrophic complications for the patient. A sound technique employed intraoperatively helps in the speedy recovery of the patient and reduces the risk of future surgical interventions. In this study, we present a medium-term outcome of our novel Lancaster cortical window technique which can be used for the removal of cemented or uncemented femoral stems.

A pair of particles in inertial microfluidics: effect of shape, softness, and position.

Lab-on-a-chip devices based on inertial microfluidics have emerged as a promising technique to manipulate particles in a precise way. Inertial microfluidics exploits internal hydrodynamic forces and the mechanical structure of particles to achieve separation and focusing. The article focuses on the hydrodynamic interaction of two particles.

Early catastrophic failure of a PINNACLE MARATHON® polyethylene acetabular liner: a report of a malpositioned PINNACLE DUOFIX HA® acetabular shell resulting in point loading and accelerated wear.

Background: Highly cross-linked polyethylene in total hip arthroplasty (THA) has been shown to decrease wear rate compared with a conventional polyethylene liner. However, it has also been reported that the manufacturing processes can cause early failure of the implant.

Case: We describe early catastrophic failure at <4 years following primary THA surgery of a PINNACLE MARATHON® polyethylene acetabular liner resulting from a malaligned PINNACLE DUOFIX HA® acetabular shell with resultant point loading.

Patella in total knee arthroplasty: to resurface or not to--a cohort study of staged bilateral total knee arthroplasty.

The aim of this study was to assess medium term results of patellar resurfacing in total knee arthroplasty, specifically looking at anterior knee pain, patellofemoral function and need for reoperation. A prospective cohort study was conducted with patients undergoing staged bilateral knee arthroplasty with the patella being resurfaced only on one side. This was due to change in the clinical practice of the senior author.

The efficacy of combined popliteal and ankle blocks in forefoot surgery.

Background: Postoperative pain following forefoot surgery can be difficult to control with oral analgesia. The aim of this study was to compare the efficacy of a combined popliteal and ankle block with that of an ankle block alone in providing postoperative analgesia following forefoot surgery.

Methods: We performed a prospective, randomized, controlled single-blind study involving sixty-three patients, twenty-six of whom had a combined ankle and popliteal block and thirty-seven of whom had an ankle block alone.

Bilateral radial head fractures in a woman with trivial trauma.

Radial head fractures are common injuries, occurring in about 20% of all acute elbow injuries. Isolated radial head fractures are not common and include about 2% of all fractures around the elbow. Bilateral radial head fractures are rare and usually associated with severe trauma and associated fractures and dislocations.

A midface swelling in a child - A possible diagnostic dilemma.

A lump on the midface of a child can pose as a diagnostic dilemma. There is a wide variety of possible differential diagnoses, ranging from simple benign conditions such as a sebaceous cyst, dermoid cyst, lipoma, neuroma and neurofibroma, to potentially devastating conditions such as odontogenic myxoma. A case of a child in which the formulation of a definite diagnosis was clinically and histologically challenging is presented.
