Less Pain, but no changes in maximal inclination angles during an overhead reach task following local anesthetic in patients with ongoing shoulder pain.

This multicenter observational study aimed to assess how pain reduction, induced by local anesthesia, affects the relative angular contributions of the shoulder girdle and trunk to the maximal angular performance during a semi-constrained overhead reach task in patients with ongoing shoulder pain. Twenty-nine individuals (age 59.0 SD 12.8 years;16-male) with symptomatic shoulders were administered corticosteroid and lidocaine injections by their attending orthopedic surgeon. Immediately before and after the injections, participants reached for a target on the ceiling ten times as high as possible while their pain levels, shoulder, and trunk movements were recorded. The analysis revealed that there was a significant reduction in pain following the injections. However, there were no significant differences in maximum shoulder and trunk inclination angles between the pre- and post-injection conditions. Notably, there were slight but statistically significant alterations in humeroscapular kinematics during the initial phase of arm elevation following the injections. In conclusion, acute pain relief following local anesthetics is not associated with immediate alterations in maximum shoulder girdle and trunk inclination angles during a semi-constrained overhead reach task in patients with ongoing shoulder pain. However, there are signs of small alterations in humeroscapular kinematics during the initial phase of arm elevation.

Agreement between physical therapists and radiologists of stratifying patients with shoulder pain into new treatment related categories using ultrasound; an exploratory study.

STUDY DESIGN: A systematic overview of the literature and an agreement study. OBJECTIVES: The aim of this study is to explore the inter-professional agreement of diagnostic musculoskeletal ultrasound (DMUS) between physical therapists (PT) and radiologists, using a new classification strategy based upon the therapeutic consequences in patients with shoulder pain. BACKGROUND: DMUS is frequently used by PTs, although the agreement regarding traditional diagnostic labels between PTs and radiologists is only fair. Nevertheless, DMUS could be useful when used as a stratifying-tool. METHODS: First, a systematic overview of current evidence was performed to assess which traditional diagnostic labels could be recoded into new treatment related categories (referral to secondary care, corticosteroid injections, physical therapy, watchful waiting). Next, kappa values were calculated for these categories between PTs and radiologists. RESULTS: Only three categories were extracted, as none of the traditional diagnostic labels were classified into the 'corticosteroid injection' category. Overall, we found moderate agreement to stratify patients into treatment related categories and substantial agreement for the category 'referral to secondary care'. Both categories 'watchful waiting' and 'indication for physical therapy' showed moderate agreement between the two professions. CONCLUSION: Our results indicate that the agreement between radiologists and PTs is moderate to substantial when labelling is based on treatment consequences. DMUS might be able to help the PT to guide treatment, especially for the category 'referral to secondary care' as this showed the highest agreement. However, as this is just an explorative study, more research is needed, to validate and assess the consequences of this stratification classification for clinical care.

Manipulation under anesthesia versus physiotherapy treatment in stage two of a frozen shoulder: a study protocol for a randomized controlled trial.

BACKGROUND: There is no consensus about the optimal treatment strategy for frozen shoulders (FS). Conservative treatment consisting of intra-articular corticosteroid infiltrations and physiotherapy are considered appropriate for most patients. However, with a conservative strategy, patients experience a prolonged rehabilitation period with a considerable amount of pain and disabilities in daily life. Also, at long term, a residual amount of pain and restriction of range of motion is frequently reported. Manipulation under anesthesia is a short and relative simple procedure with the potential to rapidly reduce symptoms and restore the range of motion. The objective of this trial is to evaluate the effectiveness of MUA followed by a PT program compared to a PT program alone, in the treatment of patients with a stage two FS. We hypothesize that the course of the disease can be shortened with MUA with a quicker functional recovery. METHODS: This is a prospective, single center, randomized controlled trial. Eligible patients will be allocated to either the manipulation (MUA) group or the physiotherapy alone (PT) group. In the MUA group manipulation will be performed under interscalene block, directly followed by an intensive physiotherapy treatment protocol, with the goal to maintain the obtained range of motion. Patients allocated to the PT group are given advice and education and receive a written protocol to hand out to their physical therapist based on the recent guideline of the Dutch Shoulder Network for the treatment of frozen shoulders. Descriptive statistics will be used to describe the sample size, patients demographics, presence of diabetes mellitus, range of motion, duration of symptoms till randomization and will be presented for each treatment group. The SPADI is used as primary functional outcome parameter. Secondary outcome parameters are; OSS, NPRS, EQ-5D 3-L, passive range of motion, WORQ-UP, duration of symptoms, usage of analgesics and adverse events. A sample size of 41 subjects in each group was calculated. Follow up is planned after 1,3 and 12 months. The length of physiotherapy treatment in both groups is variable, depending on individual progression. Differences between groups in outcome parameters will be analysed using the linear mixed modelling and the restricted maximum likelihood ratio technique for estimating the model parameters. DISCUSSION: Successful completion of this trial will provide evidence on the best treatment strategy for patients with a stage two frozen shoulder. The results of this study can lead to a better understanding for the role of manipulation in the treatment of frozen shoulders. TRIAL REGISTRATION: This trial is registered in the Dutch Trial Register under the number NTR6182 on the 20th of February 2017.

Inter-professional agreement of ultrasound-based diagnoses in patients with shoulder pain between physical therapists and radiologists in the Netherlands.

STUDY DESIGN: Reliability study. OBJECTIVES: The aim of this study was to evaluate the interrater-reliability of the interpretation of diagnostic ultrasound in patients with shoulder pain between physical therapists and radiologists. BACKGROUND: Although physical therapists in The Netherlands increasingly use diagnostic ultrasound in clinical practice, there is no evidence available on its reliability. METHODS: A cohort study included patients with shoulder pain from primary care physiotherapy. Patients followed the usual diagnostic pathway of which diagnostic ultrasound could be a part. Patients that received diagnostic ultrasound also visited a radiologist within one week for a second one. Patients and radiologists were blinded for the diagnostic ultrasound diagnosis of the physical therapists. Agreement was assessed using Cohen's kappa statistics. Subgroup analysis was performed on education and experience. RESULTS: A total of 65 patients were enrolled and 13 physical therapists and 9 radiologists performed diagnostic ultrasound. We found substantial agreement (0.63 K) between physical therapists and radiologists on the assessment of full thickness tears. The overall kappa of all four diagnostic categories was 0.36, indicating fair agreement. The more experienced and highly trained physical therapists showed moderate agreement (0.43 K) compared to only slight agreement (0.17 and 0.09 K) from the less experienced and trained physical therapists with radiologists. CONCLUSION: The reliability between physical therapists and radiologist on diagnostic ultrasound of shoulder patients in primary care is borderline substantial (Kappa = 0.63) for full thickness tears only. This level of reliability is relatively low when compared with the high reliability between radiologists. More experience and training of physical therapists may increase the reliability of diagnostic ultrasound.

Auscultation in flight: comparison of conventional and electronic stethoscopes.

OBJECTIVES: The ability to auscultate during air medical transport is compromised by high ambient-noise levels. The aim of this study was to assess the capabilities of a traditional and an electronic stethoscope (which is expected to amplify sounds and reduce ambient noise) to assess heart and breath sounds during medical transport in a Boeing C135. METHODS: We tested one model of a traditional stethoscope (3MTM Littmann Cardiology IIITM) and one model of an electronic stethoscope (3MTM Littmann Stethoscope Model 3000). We studied heart and lung auscultation during real medical evacuations aboard a medically configured C135. For each device, the quality of auscultation was described using a visual rating scale (ranging from 0 to 100 mm, 0 corresponding to "I hear nothing," 100 to "I hear perfectly"). Comparisons were accomplished using a t-test for paired values. RESULTS: A total of 36 comparative evaluations were performed. For cardiac auscultation, the value of the visual rating scale was 53 ± 24 and 85 ± 11 mm, respectively, for the traditional and electronic stethoscope (paired t-test: P = .0024). For lung sounds, quality of auscultation was estimated at 27 ± 17 mm for traditional stethoscope and 68 ± 13 for electronic stethoscope (paired t-test: P = .0003). The electronic stethoscope was considered to be better than the standard model for hearing heart and lung sounds. CONCLUSION: Flight practitioners involved in air medical evacuation in the C135 aircraft are better able to practice auscultation with this electronic stethoscope than with a traditional one.

[Promotility drugs use in critical care: indications and limits?]. / Utilisation des médicaments prokinétiques en réanimation: indications et limites?

Enteral feeding is often limited by gastric and intestinal motility disturbances in critically ill patients, particularly in patients with shock. So, promotility agents are frequently used to improve tolerance to enteral nutrition. This review summaries the pathophysiology, presents the available pharmacological strategies, the clinical data, the counter-indications and the principal limits. The clinical data are poor. No study demonstrates a positive effect on clinical outcomes. Metoclopramide and erythromycin seems to be the more effective. Considering the risk of antibiotic resistance, the first line use of erythromycin should be avoided in favor of metoclopramide.

Suspected acute coronary syndrome in a theater of operations: first management, medical evacuation, and final diagnosis: experience of the French Medical Army.

OBJECTIVE: to evaluate the treatment of the acute coronary syndrome (ACS) among soldiers stationed on a theater of operations by structures usually conceived to treat combat-related trauma. METHODS: We performed a retrospective study involving the whole medical evacuations out of a theater of operations to the benefit of the French Armed forces, for a suspected diagnosis of ACS. RESULTS: 35 patients were included in this study with 20 for a diagnosis of persistent ST-Segment Elevation Myocardial Infarction (STEMI). Only an active smoking defined a population at risk in these high medical selective soldiers. The agreement between the initial and the final diagnosis was excellent for STEMI but remains perfectible for NSTEMI. CONCLUSION: the medical structures deployed in a theater of operations were able to provide first treatment in ACS. The use of powerful diagnosis test, like troponine assay, must allow a better selection of the patients justifying a medical evacuation.

[Successful treatment of life-threatening Panton-Valentine leucocidin positive Staphylococcus aureus pneumonia with antibiotics and immunoglobulins targeting the toxin production]. / Pneumopathie nécrosante à Stapholococcus aureus sécréteur de la leucocidine de Panton-Valentine: traitement avec succès par antibiotiques et immunoglobulines à visée anti-toxinique.

We report a patient who presented a severe Panton-Valentine-secreting methicillin-susceptible Staphylococcus aureus pneumonia with threatening multi-organ failure including acute respiratory distress syndrome, cardiac failure, renal failure and disseminated intravascular coagulation. Clinical and biological disease course using empiric therapy with treatment directed against toxin production (linezolid, clindamycin and intravenous immunoglobulins) was found to be quickly effective.

[Antitoxin treatments for necrotizing pneumonia due to Panton-Valentine leukocidin-secreting Staphylococcus aureus]. / Traitements antitoxiniques et pneumopathies nécrosantes àStaphylococcus aureus sécréteurs de leucocidine de Panton-Valentine.

Staphylococcus aureus is responsible for two main clinical presentations in humans: suppurative infections and toxigenic diseases. A small percentage of S. aureus strains secrete Panton-Valentine leukocidin (PVL). This toxin is implicated in skin infections, furunculosis, osteoarticular infections, and particularly, in serious pulmonary infections known as necrotizing pneumonia, which affect immunocompetent patients with no comorbidity. A clear outline of the clinical presentation was described recently. Necrotizing pneumonia caused by PVL-secreting S. aureus strains is characterized by a combination of fever, hemoptysis, multilobar alveolar infiltrations, and leukopenia. The disease usually progresses to toxic shock or refractory hypoxemia. A number of interesting therapies targeting leukocidin have been proposed over the past few years based on in vitro data. This review focuses on the physiopathological basis and on the therapeutic relevance of various drugs.

[Gas gangrene: A serious complication of transobturator suburethral slings]. / La gangrène gazeuse : une complication grave des implants de soutènement urétraux transobturateurs.

We report a case of a gaseous gangrene of the thigh, six months after setting a polypropylene monofilament suburethral sling on transobturator position. This rare complication has severely engaged the vital prognosis of a 39-years-old woman, operate for stress urinary incontinence. According to the available data, we discuss the predictive factors of such complications.

International Cartilage Repair Society (ICRS) and Oswestry macroscopic cartilage evaluation scores validated for use in Autologous Chondrocyte Implantation (ACI) and microfracture.

OBJECTIVE: For young patients with cartilage defects, the emergence of clinically applicable cell therapy for biological joint reconstruction is an appealing prospect. Acceptation of this method as a means of standard care requires proof of being reproducible, having long-lasting mechanical integrity, and having a good clinical outcome. This study evaluates the reliability of the International Cartilage Repair Society (ICRS) score and the Oswestry Arthroscopy Score (OAS) in the assessment of regenerative cartilage repair. METHOD: A total of 101 macroscopic images of cartilage repair were made during arthroscopy 12 months post-treatment of either Autologous Chondrocyte Implantation (ACI) or microfracture. These images were examined by seven independent observers with differing levels of experience. The ICRS and OAS scores were randomly presented twice at a 4-week interval. All observers stated their predicted outcome according to actual treatment and defect size. RESULTS: ICRS and OAS scores showed both good inter- and intra observer reliability (0.62 and 0.56 for ICRS; 0.73 and 0.65 for OAS, respectively). Internal consistency (Cronbach's alpha) was satisfactory for research purposes (0.79 and 0.74, respectively). Correlation (equivalence concordance) between both scoring systems was excellent (r=0.94). All observers were inconsistent in predicting actual treatment. Test-re test reliability of estimated defect size and its correlation to true defect size were poor. These results were also applicable to the sub-analyses of the experience of the observer and the quality of imaging. CONCLUSION: The ICRS and OAS are reliable and relevant scores that are now both validated for macroscopic evaluation of cartilage repair as a research tool.

[Favorable outcome of gemcitabine-induced acute respiratory distress syndrome]. / Syndrome de détresse respiratoire aiguë à la gemcitabine d'évolution favorable.

Gemcitabine is a new important drug used to treat solid tumors including non-small cell lung cancer, pancreatic, bladder and breast cancers. Myelosuppression is the most common adverse effect. Pulmonary toxicity is rare and usually mild and self-limiting with acute dyspnea. Severe pneumonitis and potentially fatal acute respiratory distress syndrome (ARDS) have been described in patients treated for a non-small cell lung cancer. We report a case of gemcitabine-induced ARDS in a 72-year old patient treated with gemcitabine and cisplatin for a bladder cancer without lung metastasis. Administration of high doses of corticosteroids led to a prompt symptomatic improvement.

[Peripheral polyneuropathy after heat stroke]. / Polyneuropathie périphérique après coup de chaleur.

The authors report the case of a woman who developed a peripheral polyneuropathy after heat stroke. All the classical aetiologies of neuropathy were excluded. The final diagnostic was residual peripheral neuropathy provoked by heat stroke. The sequella of heat stroke are dominated by cerebellar compromise, but this case shows that peripheral polyneuropathies exist even if they are rare. They raise the issue of care because of severe neurological sequella.

Relationship between serum inositol concentration and development of retinopathy of prematurity: a prospective study.

PURPOSE: To examine the relationship between the intake of sugar inositol, serum inositol levels, and ROP in three groups of low birthweight infants receiving feedings containing various concentrations of inositol. METHODS: Infants with a birthweight <1500 g, with severe lung disease, were eligible for the study when they began enteral feedings. Infant formulas contained three different inositol concentrations: 2500, 710, and 242 micromol/L. Serum inositol concentrations were averaged over specific time intervals. A logistic regression model was used to investigate the confounding effect of duration of mechanical ventilation and oxygen therapy, birthweight, Apgar score, and serum inositol concentration on development of ROP. RESULTS: Infants receiving high inositol formula and with higher serum inositol concentrations at birth and after 30 days had a statistically significant lower incidence of severe ROP than those receiving the lower inositol formula and with lower serum concentrations (P<.05). The effective serum inositol concentration (EC90) associated with lesser disease was >215 micromol/L. By logistic regression, the odds of developing severe ROP were greater among infants with low serum inositol concentration (odds ratio=4.7, 95% confidence interval 0.90-24.8, P=.017). CONCLUSION: Inositol supplementation may help prevent the most severe form of ROP.

['Trigger thumb' in 38 children: good short-term and long-term results from surgery]. / 'Knappende duim' bij 38 kinderen: goede resultaten van operatie op korte en lange termijn.

OBJECTIVE: To determine the direct and long-term effectivity of incision of the pulley in a trigger thumb (tendovaginitis stenosans). DESIGN: Retrospective study with follow-up. METHODS: In the period 1984-1995, 38 children (24 boys and 14 girls) were diagnosed and operated on 45 trigger thumbs in the Onze Lieve Vrouwe Gasthuis (Amsterdam) and Medisch Centrum Alkmaar, the Netherlands. Data were obtained from notes, operation reports and review in follow-up, at least 2 years after the operation. RESULTS: The mean age of the children at the moment of surgery was 3 years and 2 months (range: 11 months-10.33 years). 39 out of 45 thumbs were reviewed. Four thumbs had limited postoperative function. Two of these had a revision operation. There was 1 thumb with a postoperative superficial infection. At follow-up all thumbs had maximal function. The nodule in the tendon, which was palpable in 43 out of 45 thumbs preoperatively, had (almost) disappeared in all 39 thumbs at follow-up. There was a family history of trigger thumb in 33% of the 33 patients with follow up. 18% had bilateral involvement of the thumbs. The 6 digits not included in follow-up had a normal function according to the last notes. CONCLUSION: The results of surgery in the short term are good, in the long term excellent. Few complications occur. Based on the findings, it seems advisable to operate on children with a trigger thumb if there is no spontaneous recovery within half a year. Trigger thumb is the result of a congenital tight pulley.
