Adhesive capsulitis and dynamic splinting: a controlled, cohort study
<p>Abstract</p> <p>Background</p> <p>Adhesive Capsulitis (AC) affects patient of all ages, and stretching protocols are commonly prescribed for this condition. Dynamic splinting has been shown effective in contracture reduction from pathologies including Trismus to plantar fasciitis. The purpose of this study was to examine the efficacy of dynamic splinting on patients with AC.</p> <p>Methods</p> <p>This controlled, cohort study, was conducted at four physical therapy, sports medicine clinics in Texas and California. Sixty-two patients diagnosed with Stage II Adhesive Capsulitis were grouped by intervention. The intervention categories were as follows: Group I (Control); Group II (Physical Therapy exclusively with standardized protocols); Group III; (Shoulder Dynasplint system exclusively); Group IV (Combined treatment with Shoulder Dynasplint and standardized Physical Therapy). The duration of this study was 90 days for all groups, and the main outcome measures were change in active, external rotation.</p> <p>Results</p> <p>Significant difference was found for all treatment groups (p < 0.001) following a one-way ANOVA. The greatest change with the smallest standard deviation was for the combined treatment group IV, (mean change of 29°).</p> <p>Conclusion</p> <p>The difference for the combined treatment group was attributed to patients' receiving the best PT combined with structured "home therapy" that contributed an additional 90 hours of end-range stretching. This adjunct should be included in the standard of care for adhesive Capsulitis.</p> <p>Trial Registration</p> <p><b>Trial Number</b>: NCT00873158</p
Pregabalin, celecoxib, and their combination for treatment of chronic low-back pain
Background -
The efficacy and safety of the association of celecoxib [a selective cyclooxygenase-2 (COX-2) inhibitor] and pregabalin (commonly used to control neuropathic pain), compared with monotherapy of each, were evaluated for the treatment of chronic low-back pain, a condition known to be due to neuropathic as well as nociceptive pain mechanisms.
Materials and methods -
In this prospective randomized trial, 36 patients received three consecutive 4-week treatment regimes, randomly assigned: celecoxib plus placebo, pregabalin plus placebo, and celecoxib plus pregabalin. All patients were assessed by using a visual analogue scale (VAS, 0\u2013100 mm) and the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) pain scale by an investigator blinded to the administered pharmacological treatment.
Results -
Celecoxib and pregabalin were effective in reducing low-back pain when patients were pooled according to LANSS score. The association of celecoxib and pregabalin was more effective than either monotherapy in a mixed population of patients with chronic low-back pain and when data were pooled according to LANSS score. Adverse effects of drug association and monotherapies were similar, with reduced drug consumption in the combined therapy.
Conclusions -
Combination of celecoxib and pregabalin is more effective than monotherapy for chronic low-back pain, with similar adverse effects

The morphology of human rod ERGs obtained by silent substitution stimulation
YesPurpose To record transient ERGs from the lightadapted
human retina using silent substitution stimuli
which selectively reflect the activity of rod photoreceptors.
We aim to describe the morphology of these
waveforms and examine how they are affected by the
use of less selective stimuli and by retinal pathology.
Methods Rod-isolating stimuli with square-wave
temporal profiles (250/250 ms onset/offset) were
presented using a 4 primary LED ganzfeld stimulator.
Experiment 1: ERGs were recorded using a rodisolating
stimulus (63 ph Td, rod contrast,
Crod = 0.25) from a group (n = 20) of normal
trichromatic observers. Experiment 2: Rod ERGs
were recorded from a group (n = 5) using a rodisolating
stimulus (Crod = 0.25) which varied in
retinal illuminance from 40 to 10,000 ph Td. Experiment
3: ERGs were elicited using 2 kinds of nonisolating
stimuli; (1) broadband and (2) rod-isolating
stimuli which contained varying degrees of L- and
M-cone excitation. Experiment 4: Rod ERGs were
recorded from two patient groups with rod monochromacy
(n = 3) and CSNB (type 1; n = 2).
Results The rod-isolated ERGs elicited from normal
subjects had a waveform with a positive onset
component followed by a negative offset. Response
amplitude was maximal at retinal illuminances\100
ph Td and was virtually abolished at 400 ph Td. The
use of non-selective stimuli altered the ERG waveform
eliciting more photopic-like ERG responses. Rod
ERGs recorded from rod monochromats had similar
features to those recorded from normal trichromats, in
contrast to those recorded from participants with
CSNB which had an electronegative appearance.
Conclusions Our results demonstrate that ERGs
elicited by silent substitution stimuli can selectively
reflect the operation of rod photoreceptors in the
normal, light-adapted human retina.Deutsche Forschungsgemeinschaft (DFG) (KR1317/13-1) and Bundesministerium für Bildung und Forschung (BMBF) (01DN14009) provided financial support for JK
The Influence of Social Comparison on Visual Representation of One's Face
Can the effects of social comparison extend beyond explicit evaluation to visual self-representation—a perceptual stimulus that is objectively verifiable, unambiguous, and frequently updated? We morphed images of participants' faces with attractive and unattractive references. With access to a mirror, participants selected the morphed image they perceived as depicting their face. Participants who engaged in upward comparison with relevant attractive targets selected a less attractive morph compared to participants exposed to control images (Study 1). After downward comparison with relevant unattractive targets compared to control images, participants selected a more attractive morph (Study 2). Biased representations were not the products of cognitive accessibility of beauty constructs; comparisons did not influence representations of strangers' faces (Study 3). We discuss implications for vision, social comparison, and body image

Multilocus ISSR Markers Reveal Two Major Genetic Groups in Spanish and South African Populations of the Grapevine Fungal Pathogen Cadophora luteo-olivacea
Cadophora luteo-olivacea is a lesser-known fungal trunk pathogen of grapevine which has been recently isolated from vines showing decline symptoms in grape growing regions worldwide. In this study, 80 C. luteo-olivacea isolates (65 from Spain and 15 from South Africa) were studied. Inter-simple-sequence repeat-polymerase chain reaction (ISSR-PCR) generated 55 polymorphic loci from four ISSR primers selected from an initial screen of 13 ISSR primers. The ISSR markers revealed 40 multilocus genotypes (MLGs) in the global population. Minimum spanning network analysis showed that the MLGs from South Africa clustered around the most frequent genotype, while the genotypes from Spain were distributed all across the network. Principal component analysis and dendrograms based on genetic distance and bootstrapping identified two highly differentiated genetic clusters in the Spanish and South African C. luteo-olivacea populations, with no intermediate genotypes between these clusters. Movement within the Spanish provinces may have occurred repeatedly given the frequent retrieval of the same genotype in distant locations. The results obtained in this study provide new insights into the population genetic structure of C. luteo-olivacea in Spain and highlights the need to produce healthy and quality planting material in grapevine nurseries to avoid the spread of this fungus throughout different grape growing regions
