Ultrasound-Guided Versus Landmark-Guided Local Corticosteroid Injection for Carpal Tunnel Syndrome: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Objective

To review the literature and assess the comparative effectiveness of ultrasound-guided versus landmark-guided local corticosteroid injections in patients with carpal tunnel syndrome (CTS).

Validity of systemic lupus erythematosus disease activity score (SLE-DAS) for definition of lupus low disease activity state (LLDAS)

Clinical Rheumatology - SLE disease activity score (SLE-DAS) is a novel, rapid, continuous and comprehensive score that overcomes the drawbacks of SLEDAI-2 K. Low lupus disease activity...     

The use of recombinant tissue plasminogen activator in in acute ischemic stroke is associated with increased level of BDNF

Much concern was directed towards the crucial role of recombinant tissue plasminogen activator (rt-PA) in improving neuroplasticity in patients with acute ischemic stroke. The aim of the work to investigate the effect of treating patients with acute ischemic stroke with rt-PA, on the level of brain derived neurotrophic factor (BDNF) as a marker of neuroplasticity. This study was conducted on 47 patients presenting with acute ischemic stroke (during the first 4.5 h from stroke onset); 26 patients of them eligible for receiving rt-PA (patient group) and 21 patients having contraindications for treatment with rt-PA (control group). Neurological, radiological and laboratory assessment (including BDNF serum level) were done for both groups at stroke onset (before receiving rt-PA) and at day 7. There was a statistically significant increase in BDNF serum level from day 1 to day 7 in rt-PA treated patients in comparison to control group (P-value? 0.001). Serum level of BDNF is significantly higher at the onset of stroke in female patients and non-smokers than males or smokers (P-value?=?0.011, 0.01 respectively). There was no effect of either age, body mass index, hypertension, diabetes, drug abuse, past or family history of stroke, valvular heart diseases, atrial fibrillation, cardiomyopathy, ejection fraction, carotid atherosclerotic changes, lipid profile or uric acid, on BDNF serum level measured at the onset of stroke. Treatment of patients with acute ischemic stroke with rt-PA causes significant improvement in neuroplasticity through increasing BDNF serum level.

     

Kaposi’s sarcoma in a patient with severe relapsing polychondritis

This report describes the case of a young man who developed Kaposis sarcoma (KS) after corticosteroid treatment for severe tracheal involvement of relapsing polychondritis (RP). The etiopathogenetic mechanisms that may have led to the evolution of this unusual neoplasm are discussed. To our knowledge, this is the first case reported of concomitant RP and KS.     

Incidence of cystoid macular oedema with intracameral cephalosporin or vancomycin in cataract surgery

Abstract

Purpose: To compare the incidence of pseudophakic cystoid macular oedema (CME) in patients who receive intracameral cephalosporin versus intracameral vancomycin during cataract surgery.

Methods: A retrospective chart review was conducted on subjects with the diagnosis of CME between January 1 2010 and July 31 2017. Inclusion criterion was the documentation of CME after cataract extraction. Exclusion criteria were intraoperative complication, prior history of macular oedema, epiretinal membrane, uveitis, other pre-existing retinal pathology, or other post-operative pathology including other ocular surgery in the post-operative period.

Results: The final analysis included 89 eyes with optical coherence tomography (OCT) proven CME. The incidence of pseudophakic CME in our population of 10,165 cataract surgeries after applying the above-stated exclusion criteria was 0.88%. The incidence of pseudophakic CME in subjects who received intracameral cephalosporin was 0.87% (mean age in years 69?±?11; 31 male [39%], 48 female [61%]). The incidence of pseudophakic CME in subjects who received intracameral vancomycin was 0.96% (mean age in years 66?±?13; 4 male [40%], 6 female [60%]). Pearson’s chi-square test demonstrated no significant difference between these groups (p?=?0.7705).

Conclusions: There was no statistical difference in the incidence of pseudophakic CME in subjects who received intracameral cephalosporin versus intracameral vancomycin during cataract surgery.     

Electronic Medical Records and Electronic Health Records: Overview for Nurse Practitioners

Electronic medical records (EMRs) and electronic health records (EHRs) have become essential systems by which nurse practitioners (NPs) communicate vital patient information to other members of the health care team as well as to patients. In this article we examine the important distinctions between EMRs and EHRs; review the genesis of these types of records; summarize applicable provisions of the Health Insurance Portability and Accountability Act from a recent legal case centered around NP utilization of EMRs and EHRs; address open patient access to medical information; and examine threats to security. Suggestions are offered on ways in which NPs can safeguard confidential patient information.     

Parasympathetic nervous system activity and children's sleep

We examined indices of children's parasympathetic nervous system activity (PNS), including respiratory sinus arrhythmia during baseline (RSAB) and RSA reactivity (RSAR), to a laboratory challenge, and importantly the interaction between RSAB and RSAR as predictors of multiple parameters of children's sleep. Lower RSAR denotes increased vagal withdrawal (reductions in RSA between baseline and task) and higher RSAR represents decreased vagal withdrawal or augmentation (increases in RSA between baseline and task). A community sample of school‐attending children (121 boys and 103 girls) participated [mean age = 10.41 years; standard deviation (SD) = 0.67]. Children's sleep parameters were examined through actigraphy for 7 consecutive nights. Findings demonstrate that RSAB and RSAR interact to predict multiple sleep quality parameters (activity, minutes awake after sleep onset and long wake episodes). The overall pattern of effects illustrates that children who exhibit more disrupted sleep (increased activity, more minutes awake after sleep onset and more frequent long wake episodes) are those with lower RSAB in conjunction with lower RSAR. This combination of low RSAB and low RSAR probably reflects increased autonomic nervous system arousal, which interferes with sleep. Results illustrate the importance of individual differences in physiological regulation indexed by interactions between PNS baseline activity and PNS reactivity for a better understanding of children's sleep quality.
