Outcomes of Total Ankle Replacement Versus Ankle Arthrodesis for the Treatment of End-Stage Ankle Arthritis: A Concise Follow-up, at a Minimum of 10 Years, of a Previous Report.

Abstract: Despite the increasing utilization of total ankle replacement (TAR) for end-stage ankle arthritis, there remains a paucity of long-term follow-up data comparing arthroplasty to arthrodesis. The aim of the current paper was to provide the long-term clinical outcomes of TAR and ankle arthrodesis (AA), measured with use of validated scoring instruments, in a prospective multicenter cohort of patients with ankle arthritis. This cohort from the Canadian Orthopaedic Foot and Ankle Society (COFAS) Prospective Ankle Reconstruction Database comprised patients who underwent TAR or AA between 2001 and 2007.

Cutaneous basophil infiltration in atopic dermatitis is associated with abundant epidermal infiltration of helper T cells: A preliminary retrospective study.

Atopic dermatitis (AD) is a heterogenous inflammatory skin disorder. Our previous study revealed that basophil infiltration in skin is observed in approximately 60% of AD cases. However, the clinical and histological characteristics of AD associated with basophil infiltration remain unclear.

Development of a Skin-Directed Scoring System for Stevens-Johnson Syndrome and Epidermal Necrolysis: A Delphi Consensus Exercise.

Importance: Scoring systems for Stevens-Johnson syndrome and epidermal necrolysis (EN) only estimate patient prognosis and are weighted toward comorbidities and systemic features; morphologic terminology for EN lesions is inconsistent.

Objectives: To establish consensus among expert dermatologists on EN terminology, morphologic progression, and most-affected sites, and to build a framework for developing a skin-directed scoring system for EN.

Evidence Review: A Delphi consensus using the RAND/UCLA appropriateness criteria was initiated with a core group from the Society of Dermatology Hospitalists to establish agreement on the optimal design for an EN cutaneous scoring instrument, terminology, morphologic traits, and sites of involvement.

Towards understanding Müller-Weiss disease from an analysis of 95 cases.

Background: The single existing classification of Müller-Weiss Disease (MWD), based solely upon Méary's angle, serves neither as guide for prognosis nor treatment. This accounts for lack of gold standard in its management.

Methods: Navicular compression, medial extrusion, metatarsal lengths, Kite's, lateral and dorsoplantar talo-first metatarsal angles were measured in 95 feet with MWD.

Decreased peripheral basophil counts in urticaria and mouse model of oxazolone-induced hypersensitivity, the latter suggesting basopenia reflecting migration to skin.

A decrease in the number of basophils in the peripheral blood, or basopenia, has been noted, reflecting the activity of chronic spontaneous urticaria (CSU). Infiltration of basophils into the skin has also been reported, but the mechanism of basopenia in CSU has not been clarified. The phenomenon of basopenia during the active phase of urticaria was confirmed, and basophil numbers increased following symptom improvement in 15 out of 17 patients treated with omalizumab and in 13 of 15 patients treated with antihistamines.

A Prospective Study Assessing Wound Complications in a Series of Foot and Ankle Patients Treated With Enoxaparin: A Baseline for Future Studies.

Background and objective Low-molecular-weight heparin (LMWH) prophylaxis has now become the gold-standard practice in patients requiring lower limb immobilization. We had noticed an increase in the incidence of wound-healing problems at our center, and the severity of the problems was found to be worse in patients undergoing foot and ankle surgery since we had adopted this practice. In this study, we aimed to describe the incidence and severity of wound-healing problems in this group of patients.

The management of osteoporotic acetabular fractures: Current methods and future developments.

Acetabular fractures in the elderly are challenging. Management is complicated by patients' poor physiological status and osteoporotic bone. Analysis of the management of these patients must be separated from the treatment of younger patients.

Detection of Mast Cells and Basophils by Immunohistochemistry.

Staining cells or tissues with basic dyes was the mainstay of mast cell and basophil detection methods for more than a century following the first identification of these cell types using such methods. These techniques have now been largely supplanted by immunohistochemical procedures with monoclonal antibodies directed against unique constituents of these cell types. Immunohistochemistry with antibodies specific for the granule protease tryptase provides a more sensitive and discriminating means for detecting mast cells than using the classical histochemical procedures, and using antibodies specific for products of basophils (2D7 antigen and basogranulin) has allowed detection of basophils that infiltrate into tissues.

Rapidly Progressive Osteoarthritis and Acetabular Bone Loss Outcomes for Patients Undergoing Primary Total Hip Replacement.

Rapidly progressive osteoarthritis (RPO) is a rare condition which is poorly understood. Limited published literature is available. Reported here is a cohort of patients with RPO and acetabular bone loss who underwent primary THA.

Penile calciphylaxis: A retrospective case-control study.

Background: Calciphylaxis is a rare disorder characterized by skin necrosis caused by calcium deposition within vessels, thrombosis, and subsequent tissue ischemia. Penile involvement may rarely occur.

Objective: To identify risk factors, diagnosis, management, and mortality of patients with penile calciphylaxis.

Use of teledermatology by dermatology hospitalists is effective in the diagnosis and management of inpatient disease.

Background: Patient outcomes are improved when dermatologists provide inpatient consultations. Inpatient access to dermatologists is limited, illustrating an opportunity to use teledermatology. Little is known about the ability of dermatologists to accurately diagnose disease and manage inpatients with teledermatology, particularly when using nondermatologist-generated clinical data.

Eosinophils, basophils and type 2 immune microenvironments in COPD-affected lung tissue.

Although elevated blood or sputum eosinophils are present in many patients with COPD, uncertainties remain regarding the anatomical distribution pattern of lung-infiltrating eosinophils. Basophils have remained virtually unexplored in COPD. This study mapped tissue-infiltrating eosinophils, basophils and eosinophil-promoting immune mechanisms in COPD-affected lungs.

A Prospective Randomized Study Comparing Postoperative Pain, Biological Fixation, and Clinical Outcomes Between Two Uncemented Rotating Platform Tibial Tray Designs.

Background: With the demand for arthroplasty increasing worldwide year on year, there is a drive to improve prosthesis longevity. Biological fixation from cementless implants has been one method of trying to achieve this. We hypothesized that the addition of a hydroxyapatite (HA) coating and 4 pegs to a porous-coated tibial tray would provide a reduction in time to implant osseointegration, allowing for normal physiological stress transfer, thus improving early postoperative pain and rehabilitation as well as the elimination of radiolucent lines (RLLs).

Staphylococcus aureus internalization in mast cells in nasal polyps: Characterization of interactions and potential mechanisms.

Background: Chronic rhinosinusitis (CRS) with nasal polyps is a common chronic condition. The exact cause of nasal polyps remains unknown. Recently, we made the novel observation of intracellular localization of Staphylococcus aureus within mast cells in nasal polyps.

Mast cell chymase impairs bronchial epithelium integrity by degrading cell junction molecules of epithelial cells.

Background: An increased degree of mast cell (MC) degranulation and damage to the epithelial lining are prominent features of bronchial asthma. In asthmatic airways, it seems likely that epithelial cells will be exposed to increased concentrations of proteases from MC, though their actions on the epithelium are still not very clear.

Methods: Bronchial rings from human lung tissue or 16HBE cell monolayer were incubated with MC chymase in different doses or various inhibitors.

Catastrophic ceramic liner failure-The subtle signs of a non-engaged ceramic liner.

Ceramic earrings have an established and successful history in total hip replacement. Occasionally, these articulations have problems, which include squeaking and implant fracture.

Postdischarge Unscheduled Care Burden After Lower Limb Arthroplasty.

Background: In contrast to postdischarge arthroplasty readmission rates, the unscheduled reattendance burden to primary care is under-reported. Understanding reasons for reattendance would allow for implementation of strategies to reduce this burden. The present study aims to quantify the out-of-hours (OOH) general practitioner and emergency department (ED) service reattendance burden and readmission rate after primary total hip arthroplasty and total knee arthroplasty, with estimation of the associated costs.
