A Rare Case of Awkward Gait: The Tethering Effect of a Unilateral Iliofemoral Fibrous Band.

Case: A young girl without pertinent medical history presented with a leg length discrepancy and an awkward gait disturbance. After a rapid growth spurt during the following year, other symptoms became obvious, she developed an inability to sit crossed legged, and her range of motion of the left hip decreased. Hip magnetic resonance imaging demonstrated a left unilateral fibrous band between the iliac wing and the greater trochanter.

Management of neglected post-traumatic ipsilateral distal femoral and proximal tibial epiphysiodeses in adolescent: Case report.

Introduction: It is important to remember the risk of post-traumatic epiphysiodesis in the context of high-speed impacts around the knee. This clinical case illustrates the risk of lower limb length discrepancy resulting from this, the treatment and management thereof. This case is unique in that it presents two ipsilateral distal femoral and proximal tibial epiphysiodeses, with secondary inequality of these two bone segments.

How to avoid systematic postoperative blood test after total hip arthroplasty: A new risk scoring system compared to Wu's score.

Background: Routine laboratory studies are often performed following total hip arthroplasty (THA). However, lately, their necessity has been challenged and risk factors for postoperative transfusion are still debated. Recently, a risk scoring system to single out patients that should have a postoperative blood test has been published by Wu et al.

[Influence of age, growth potential and functionality in the management of bone tumours in children : example of the rotationplasty].

Malignant bone tumours in children are rare diseases whose survival rate has progressively improved in recent years thanks to advances in pharmacology, surgery and radiotherapy. We present the particular case of a very young child with Ewing's sarcoma of the thigh. We discuss the influence of this young age on short and long term care.

Single-Dose 13-Valent Conjugate Pneumococcal Vaccine in People Living With HIV - Immunological Response and Protection.

Background: Patients living with HIV (PLHIV) are prone to invasive pneumococcal disease. The 13-valent conjugated pneumococcal vaccine (PCV13) is currently recommended for all PLHIV, followed in most guidelines by a 23-valent polysaccharide pneumococcal vaccine. Data are scarce concerning the immunological efficacy of PCV13 among PLHIV.

Intramolecular Photoreactions of (5S)-5-Oxymethyl-2(5H)-furanones as a Tool for the Stereoselective Generation of Diverse Polycyclic Scaffolds.

The photoactivated evolution of a series of enantiomerically pure 5-oxymethyl-2(5H)-furanones has been investigated. The observed intramolecular photoreactions have proven to be a straightforward entry to diverse and stereochemically rich fragment-molecules, most of which contain the privileged tetrahydropyran (THP) scaffold. The formation of the THP involves a 1,5-hydrogen atom transfer process, leading to a diradical intermediate that recombines to form a new σ C-C bond.

Multilingual event extraction for epidemic detection.

Objective: This paper presents a multilingual news surveillance system applied to tele-epidemiology. It has been shown that multilingual approaches improve timeliness in detection of epidemic events across the globe, eliminating the wait for local news to be translated into major languages. We present here a system to extract epidemic events in potentially any language, provided a Wikipedia seed for common disease names exists.

Batch versus flow photochemistry: a revealing comparison of yield and productivity.

The use of flow photochemistry and its apparent superiority over batch has been reported by a number of groups in recent years. To rigorously determine whether flow does indeed have an advantage over batch, a broad range of synthetic photochemical transformations were optimized in both reactor modes and their yields and productivities compared. Surprisingly, yields were essentially identical in all comparative cases.

Nursing assessment and management of patients with head injuries.

There are approximately 500,00 head injuries each year in the United States. Head injuries are also the leading cause of death and disability for persons under the age of 40. These injuries are frequently treated in intensive care units (ICU) around the country.

Alkyl-polyacrylate esters are strong mucosal adjuvants.

Synthetic polymers were examined for their potency to enhance mucosal immune responses to inactivated antigens. Aqueous solutions of polyacrylic acid with a MW of 450 kDa (p[AA]) or an butyl-ester thereof with 16% esterification (Butyl16-p[AA]) plus antigen were administered twice intranasally in mice with a 2 week interval. The frequency of IgA-antibody secreting cells (ASCs) in lung cell suspensions was determined 1 week after the second immunisation.

Sulfolipo-cyclodextrin in squalane-in-water as a novel and safe vaccine adjuvant.

Previously, we described synergistic adjuvanticity of combinations of synthetic sulfolipo(SL)-derivatives of polysaccharide (SL-polysaccharides) and squalane-in-water emulsions (squalane/W). In this paper, effects of type of polysaccharide and nature of oil on adjuvanticity, reactogenicity and stability are described. SL-derivatives of the following polysaccharides were synthesised: synthetic polysucroses with weight-average molecular weight (MW) of 400,000 (Ficoll400), 70,000 (Ficoll70) and 39,000 Da (Ficoll39), polyfructose of 5,000 Da (inulin), linear polyglucose of 1,200 Da (maltodextrin) and cyclic polyglucose of 1,135 Da (beta-cyclodextrin).

Effect of various adjuvants on secondary immune response in chickens.

Stimulatory effects of several types of adjuvants on secondary antibody response to inactivated Newcastle disease virus (iNDV) were examined in chickens. For this purpose, animals were primed with iNDV without adjuvant resulting in a low but significant antibody response, boosted with iNDV plus adjuvant 3 weeks later, and analysed for specific antibody titres in serum 3 weeks after the booster. Water-in-mineral oil emulsion (W/O) caused significant increase in antibody titres measured in an indirect enzyme-linked immunosorbent (ELISA), haemagglutination inhibition (HI), and virus neutralisation (VN) assay.

Quantitative analysis of a synthetic adjuvant by an immunoassay.

Antibodies against a sulpholipo-derivative of synthetic polysucrose (SL-Ficoll) were prepared with the purpose of developing a detection system for this adjuvant component. SL-Ficolls with polysucrose backbones of 400 kDa (SL-Ficoll400) or 22 kDa (SL-Ficoll22) were not immunogenic. However, SL-Ficoll22 conjugated to bovine serum albumin (SL-Ficoll22-BSA) induced high levels of specific antibodies against SL-Ficoll in mice as determined by an indirect ELISA with either SL-Ficoll400 or SL-Ficoll22 as coating antigen.

Analysis of oral uptake of a synthetic adjuvant by an immunoassay with monoclonal antibodies.

A blocking ELISA with specific antibodies against a synthetic sulpholipo-polysucrose (SL-Ficoll400) was developed to quantify this vaccine adjuvant component in faeces with the purpose of estimating the uptake thereof by the gastrointestinal tract after oral administration. Specific monoclonal antibodies (MABs) prepared against SL-Ficoll400 did not cross-react with components in murine faeces. SL-Ficoll400 inhibited the reactivity of the MABs in a dose-dependent fashion in the blocking ELISA and the concentration causing 50% inhibition (IC50) was about 1 microg SL-Ficoll400 per milliliter.

Alkyl-esters of polyacrylic acid as vaccine adjuvants.

Previously, we demonstrated that polyacrylic acid (PAA) augmented significantly the immune response to inactivated Newcastle disease virus (iNDV) in chickens, but that efficacy was insufficient to replace the water-in-mineral oil (W/O) adjuvant applied for boosting primed animals. Attempting to improve its adjuvanticity, PAA with weight-average molecular weight (Mw) of 450 kDa was grafted with alkyl-chains by esterifying the carboxylic groups with octanol and butanol. The butyl-PAA and octyl-PAA esters obtained varied in degree of esterification between 10% and 92%.

Sciatic nerve regeneration through venous or nervous grafts in the rat.

This study analyses the interest of isologous venous grafts filled with saline or with Schwann cells versus nerve grafts as guides for regeneration of the sciatic nerve in 35 Wistar rats. Electrophysiological parameters (conduction velocities and distal latencies of motor responses) and the functional index of De Medinacelli were measured several times from 1 month to 1 year after surgery. An histological analysis was performed on 2 control rats and on 3 rats killed 6 or 12 months after surgery: the total number of fibers was counted on a montage photoprint of the whole nerve, and the diameters of axons and the thickness of the myelin sheath were measured on digitized images.

Non-toxic antiseptic irrigation with chlorhexidine in experimental revascularization in the rat.

The effect of different wound irrigation fluids upon femoral arteries and veins was investigated in the rat, using microsurgical techniques. Toxicity was evaluated by microscopical observation after selective staining of histological slides. Povidone-iodine, 10%, proved to be a very irritant solution, provoking an attack on the vascular endothelium and secondary thrombosis.

[Osteoid osteoma of the distal end of the radius. Review of the literature in light of a case].

A case of osteoid osteoma in the distal extremity of the radius is reported. Clinical examination, treatment and clinical course are described and previous publications are reviewed.

Carpal tunnel syndrome in childhood: report of five new cases.

Carpal tunnel syndrome is a condition rarely encountered during the growth period. We describe five new cases in two large Belgian university hospitals. One case concerned a 2-year-old child suffering from disseminated angiomatosis, an association not previously reported.
