The rate of total knee arthroplasty (TKA) utilization in younger patients (< 65 years old) is increasing. Little is known regarding demographics and in-hospital outcomes in this population. The National Hospital Discharge Survey (NHDS) database was searched using International Classification of Diseases, Ninth Revision (ICD-9) procedure codes for patients admitted to U.S. hospitals for unilateral primary TKA between 2001 and 2010. Patients were separated into young (< 65 years of age) and senior cohorts (≥ 65 years of age)...

A 55-year-old woman was diagnosed with aseptic meningitis at the age of 43 and 44. She developed sudden fever and headache, and she showed nuchal rigidity. Cerebrospinal fluid examination revealed pleocytosis (cell count 208/mm(3)) and was positive for herpes simplex virus type 2 (HSV-2) DNA by PCR. Acyclovir was started on the first day of admission, and she was complete recovery. Preserved cerebrospinal fluid specimen from aseptic meningitis at the age of 44 was also positive for HSV-2 DNA by PCR. She was diagnosed with HSV-2 associated recurrent aseptic meningitis (Mollaret's meningitis) with a recurrence after 11-year interval...

Chitinase gene from the carnivorous plant, Drosera rotundifolia , was cloned and functionally characterised. Plant chitinases are believed to play an important role in the developmental and physiological processes and in responses to biotic and abiotic stress. In addition, there is growing evidence that carnivorous plants can use them to digest insect prey. In this study, a full-length genomic clone consisting of the 1665-bp chitinase gene (gDrChit) and adjacent promoter region of the 698 bp in length were isolated from Drosera rotundifolia L...

BACKGROUND: Unicompartmental total knee arthroplasty (UKA) is a well-established treatment option for unicondylar osteoarthritis, and generally leads to better functional results than tricompartimental total knee arthroplasty (TKA). However, revision rates of UKAs are reported as being higher; a major reason for this is aseptic loosening of the tibial component due to implant-cement-bone interface fatigue. The objective of this study was to determine the effects of trabecular bone preparation, prior to implantation of tibial UKAs, on morphological and biomechanical outcomes in a cadaver study...

BACKGROUND: Aseptic loosening is a significant impediment to joint implant longevity. Prosthetic wear particles are postulated to play a central role in the onset and progression of periprosthetic osteolysis, leading to aseptic loosening of the prosthesis. METHODS: We investigated the inhibitory effects of a lentivirus-mediated short hairpin RNA that targets the TNF-alpha gene on the particle-induced inflammatory and osteolytic changes via macrophages both in vitro and in vivo...

BACKGROUND: Cementless fixation of total hip arthroplasties (THAs) is often favored in young, high-demanding patients due to the conservation of valuable bone-stock and easier revision if loosening has occurred. Long-term outcome data of the spongy metal structured implant used in the present study in patients younger than 65 years are still lacking. METHODS: We conducted a retrospective chart review and functional investigation (Merle d'Aubigné score, SF-12) of patients younger than 65 years at implantation treated with a spongy metal structured THA (n = 79) from one orthopedic university center from 1985 to 1989...

In the present study, we compare a classical slow freezing (SLF) method and an aseptic vitrification (Vitrif) technique to cryopreserve a stable primordial germ cell (PGCs) line issued from the Ardennaise chicken breed. Viability immediately after warming was close to 80% and did not differ between the two cryopreservation methods. Proliferation tended to be slower for both cryopreservation methods compared with controls, but the difference was significant only for Vitrif. No difference was found between the two methods after flow cytometry analysis of stage-specific embryonic antigen-1 expression and reverse transcription-polymerase chain reaction on several factors related to PGC phenotype...

BACKGROUND: Loss of teeth affects the individual's health. Many factors determine the need to wear a removable dental prosthesis. Due to nature of design, age and lack of awareness, prosthesis often are neglected to maintain in an aseptic condition leading to microbial contamination. This provided an impetus for the present study with the aim of determining the microbial contamination of removable dental prosthesis. METHODOLOGY: Total, 45 patients wearing removable dental prosthesis were randomly selected...

INTRODUCTION: With the rising number of total hip arthroplasties (THAs) each year, it is increasingly important for surgeons to have evidence-based information on which to determine how often patients should be examined postoperatively. The purpose of this research was to determine whether it is possible to identify - based on Harris Hip Score (HHS) - early signs or predictors of THA failure so that methods of postoperative follow-up can be scheduled in advance of the time frame indicated by those predictors of failure...

The role of joint replacement in the treatment of osteoarthritis of the thumb carpometacarpal joint is a subject of considerable controversy in the current literature. In German-speaking countries this technique is used much less frequently than resection procedures. Aseptic loosening of the prosthesis is believed to be the major cause of the high failure rates reported for cemented and uncemented types of implants. In this study the different implant designs were evaluated on the basis of the results reported in the international literature...

BACKGROUND: The term "aseptic meningitis" encompasses cases of meningitis with negative bacterial CSF culture, which predominantly are of viral etiology. While the clinical course is usually benign, complications such as encephalitic involvement resulting in a more severe clinical course may occur. Dysfunction of the blood-brain-barrier (BBB), which is a prerequisite for viral entry into the brain parenchyma, can be approximated using the CSF/serum albumin ratio, readily obtainable in routine CSF analysis...

The aim of this study was to investigate the genetic variability of echovirus 6 (E6) isolates from environmental samples and clinical cases of aseptic meningitis from 2006 to 2014. The analysis of the VP1 region showed the extensive diversity (up to 18.8%) and revealed that E6 circulating in Poland belong to four groups. Environmental strains clustered in three groups excepting the 2012 outbreak group, which shows the sudden introduction of new epidemic variant with Asiatic origin. Data from the study established relationships of E6 from Poland with previously characterized strains and confirmed the importance of both clinical and environmental surveillance...

INTRODUCTION: Total hip arthroplasty (THA) is a common surgery presenting well-known failures that may require surgical revision. To reduce the risk of hip dislocation after revision THA, we hypothesize the interest of the use of a new generation dual mobility cup by evaluating its survival and complication rates. MATERIALS AND METHODS: We analyzed the survival and the failures rate of 91 patients who underwent revision THAs with a specific dual mobility cup Novae® E TH (SERF, Décines-Charpieu, France)...
