Surgical interventions for anterior shoulder instability in rugby players: A systematic review

AIM: To systematically evaluate the evidence-based literature on surgical treatment interventions for elite rugby players with anterior shoulder instability. METHODS: We conducted a systematic review according to the PRISMA guidelines. A literature search was performed in PubMed, EMBASE and Google Scholar using the following search terms: rugby and shoulder in combination with instability or dislocation . All articles published from inception of the included data sources to January 1(st) 2014 that evaluated surgical treatment of elite rugby players with anterior shoulder instability were examined. RESULTS: Only five studies were found that met the eligibility criteria. A total of 379 shoulders in 376 elite rugby union and league players were included. All the studies were retrospective cohort or case series studies. The mean Coleman Methodological Score for the 5 studies was 47.4 (poor). Owing to heterogeneity amongst the studies, quantitative synthesis was not possible, however a detailed qualitative synthesis is reported. The overall recurrence rate of instability after surgery was 8.7%, and the mean return to competitive play, where reported, was 13 mo. CONCLUSION: Arthroscopic stabilization has been performed successfully in acute anterior instability and there is a preference for open Latarjet-type procedures when instability is associated with osseous defects

Proximal femoral excision with interposition myoplasty for cerebral palsy patients with painful chronic hip dislocation

Purpose: Proximal femoral excision is a salvage procedure for painful chronic hip dislocation in cerebral palsy (CP) patients. The primary objective of this article is to describe our experience of an amplified interposition myoplasty, with appropriate peri-operative pain and tone management strategies, in a cohort of non-ambulatory CP patients with painful chronic hip dislocation. Our secondary objective is to present the clinical outcomes of these patients. Methods: We describe our experience in 20 CP patients (25 procedures) at mean 54-month (range 27–169) follow-up with a surgical technique that includes an augmented interposition myoplasty and tone management. The indications for surgery were pain (21 hips), poor sitting tolerance (11) and difficulty with perineal care (8). Results: The mean age was 22 years (range 10–40) with 11 patients Gross Motor Function Classification Scale (GMFCS) IV and 9 patients GMFCS V. Mean length of stay was 13 days (3–35). One procedure required revision at 12 months. Mean pain score improved from 7.8 (5–10) pre-operatively to 2.8 (1–5) post-operatively (p  <  0.001). Sitting tolerance improved in all patients and in 75 % (15) perineal care was easier. Conclusions: Our interposition myoplasty technique with individualised pain/tone management has good outcomes in this cohort of patients with multiple co-morbidities

Extended education at college in India. Advancing equity through the extension of public academic support programmes for students from the socially and economically disadvantaged groups

The paper seeks to expand our knowledge on the importance of public academic support programmes (ASPs) in higher education (HE) in India, which extend supplementary instruction with the aim to improve academic performance and support academic efforts of students from the socially and economically disadvantaged groups (SEDGs). This paper shows that students from the most disadvantaged amongst the SEDGs, that is, those residing in rural areas and women who experience multiple barriers that compound the effects of their disadvantages, have taken advantage of supplementary instruction classes. These classes have allowed HEIs to account for students\u27 academic needs and challenges related to their socioeconomic disadvantages, that remain unmet in regular classrooms. By targeting educational resources to students who are most disadvantaged, these programmes compensate for the absence of parental support and recognises the underlying socio-economic obstacles of students from achieving academic success at college. Given the acknowledged role of higher education in providing economic and social benefits to individuals, the paper argues that oncampus state enabled ASPs targeting students from the SEDGs make HE in India more equitable and contribute in reducing social inequalities in the wider society.

Performance Evaluation of Hybrid Coding of Images Using Wavelet Transform and Predictive Coding

Image compression techniques are necessary for the storage of huge amounts of digital images using reasonable amounts of space, and for their transmission with limited bandwidth. Several techniques such as predictive coding, transform coding, subband coding, wavelet coding, and vector quantization have been used in image coding. While each technique has some advantages, most practical systems use hybrid techniques which incorporate more than one scheme. They combine the advantages of the individual schemes and enhance the coding effectiveness. This paper proposes and evaluates a hybrid coding scheme for images using wavelet transforms and predictive coding. The performance evaluation is done using a variety of different parameters such as kinds of wavelets, decomposition levels, types of quantizers, predictor coefficients, and quantization levels. The results of evaluation are presented

Green synthesis of silver nanoparticles using Fagopyrum esculentum starch: antifungal, antibacterial activity and its cytotoxicity

52-63Silver nanoparticles (AgNPs) have been synthesized using Fagopyrum esculentum starch as a stabilizing and reducing agent. This reaction was carried out in an autoclave at 15 psi, 121°C for 20 min. UV-visible spectrum of the colloidal nanoparticles showed the surface plasmon absorption band with maximum absorbance at 418 nm. Interaction between functional groups present in the starch and nanoparticles were analyzed by Fourier-transform infrared spectroscopy (FTIR). Size of the synthesized nanoparticles was found to be in the range of 20-30 nm, as revealed from transmission electron microscopy (TEM). The X-ray diffraction analysis revealed the face-centred cubic (fcc) geometry of silver nanoparticles. The nanoparticles were found to be good antifungal agents against Aspergillus niger. The antibacterial activity of the nanoparticles was also studied. The nanoparticles showed higher inhibitory activity against Gram-negative bacteria (Escherichia coli) than the Gram-positive bacteria (Staphylococcus aureus). These results thus show that F. esculentum starch stabilized AgNPs could be used as a promising antimicrobial agent against bacteria the fungi In vitro cytotoxicity assessment of starch stabilized AgNPs has shown no significant cytotoxic effect on human cervical carcinoma cells lines (HeLa) by MTT assay and AgNPs concentration at 200 ug/ml of showed 86% cell viability

Traumatic Retrobulbar Haemorrhage: Aetio-pathology and management

Retrobulbar haematoma following blunt orbital trauma is a rare,but potentially serious complication, since it can evolve rapidly from visual impairment to permanent loss of vision. This sight-threatening situation most commonly arises from orbital bleeding accompanying undisplaced fractures of the orbital walls, an event that increases the pressure inside theorbit and results in vascular damage to the optic nerve. The clinical presentation includes pain, exophthalmos with proptosis, and internal ophthalmoplegia, with impairment or loss of the pupillary reXex. A thin-layer orbital CT scan is an essential diagnostic aid. Therapy is based on orbitaldecompression, via different surgical approaches, with the intention of reducing the pressure on the nerve and vascular structures inside the orbit. Emergent management is of utmost importance as any delay between the onset of symptoms and treatment can have a significant effect onrecovery
