Low Dose Dexamethasone in Supraclavicular Blocks

Rheumatoid ArthritisOsteoarthritis2 more

Brachial plexus nerve blocks provide superior analgesia over opioids while avoiding unwanted side effects. Single shot blocks with local anesthetic alone usually do not last the duration of the acute post-surgical pain period. This has led to the exploration of multiple adjuvants to increase the duration of single shot blocks, the most promising adjuvant being dexamethasone. Peri-neural administration is an off-label use of dexamethasone. While no adverse events have been reported in human clinical studies, logic would dictate that we minimize the dose needed to produce the desired effect. Most studies thus far have used peri-neural dexamethasone doses ranging from 4-10 mg. However, Albrecht et al. found no difference in block duration comparing 4 mg and 8 mg doses while Liu et al. reported equivalent block duration using doses of 1, 2 and 4 mg. Recent studies have evaluated whether systemic and peri-neural administrations of dexamethasone are equivalent, which would in turn imply a site of action. Results have been mixed. Four studies concluded peri-neural and intravenous administration are equivalent at prolonging analgesia, though one study had methodological errors, including the administration of intravenous dexamethasone to all patients. All of these studies used dexamethasone doses of 8 to 10 mg. One study where a lower dose (4 mg) was used found that peri-neural administration prolonged block duration whereas intravenous did not. With that, the rationale of our study is to determine if equivalent block-prolonging analgesia can be achieved using low dose (1 mg) dexamethasone given peri-neural or intravenous. Clinical experience at our centre has been that 1 mg dexamethasone added to 20 mL produces similar block duration to that reported in published studies using higher doses.

Evaluation of the Analgesic Efficiency of the Transcutaneous Neurostimulation in the Charcot Syndrome...

CHARCOT MARIE TOOTH DISEASE

The Charcot syndrome Marie Tooth is the most frequent hereditary neuromuscular diseases: there is no curative treatment at present, on the other hand precautionary measures can be taken (physiotherapy, port of splints, orthopaedic surgery and technical assistants). In the literature and in our recent study (evaluation of the pain in the disease of CMT - Reference center of the neuromuscular diseases - CHU Bow) the frequency of the pain is important varying from 66 to 96 % cases, affecting especially hands and lower limbs. The care of the pain in the Charcot syndrome Marie Tooth is not codified. The transcutaneous neurostimulation(TENS) is a not medicinal and not invasive therapeutics, without any brought back collateral effect, used at the same time in the chronic pain and acute since 1960, as well for the neuropathic pains that musculo-scrawny. No study was realized this day on the use of the TENS with analgesic aim in the CMT. We suggest studying the analgesic efficiency of the TENS in the Charcot syndrome Marie Tooth on the pains of lower limbs, the most frequent painful location in our recent works. The main objective will be to analyze the improvement of the pain of lower limbs, based on the decrease of the analogical visual scale(ladder) (EVA), at least 30 %. The secondary objectives will be to estimate repercussions on the functional capacities ( ONLS), the quality of life (SF(sci-fi) 12), the satisfaction (EVA), the global impression(printing) of change ( PGIC), the consumption of analgesic, DN4, NPSI (Neuropathic Pain Symptom Inventory), Concise Questionnaire of the Pains ( QCD), HAD (Hospital Anxiety and Depression scale).

Influence of Pronator Teres Release on Treatment of Median Nerve Compression Neuropathy

Median Nerve Compression

The investigators are comparing two standard of care procedures which can be performed at the same time, or sequentially. The hypothesis being tested is whether simultaneous release of both the carpal Tunnel and the Pronator Teres results in a better outcome in terms of symptom relief and recurrence than Carpal Tunnel Release alone when signs and symptoms of both carpal tunnel and pronator Teres syndromes are present.

Treatment for Ulnar Neuropathy at the Elbow

Peripheral Nervous System DiseasesNerve Compression Syndromes1 more

The purpose of the study is to investigate utility and appropriateness of treatment interventions taking into account the presumed mechanisms of two main varieties of ulnar neuropathy at the elbow (UNE). The investigators hypothesize that in patients with UNE under the humeroulnar aponeurosis (HUA) surgical HUA release (simple decompression) is superior to conservative treatment. By contrast, in patients with UNE at the retroepicondylar (RTC) groove surgical HUA release (simple decompression) should not be superior to conservative treatment.

Carpal Tunnel Syndrome Evaluation With Ultrasound in Rheumatoid Arthritis Patients

Median Nerve Entrapment

In rheumatoid arthritis (RA) patients, the diagnosis of Carpal tunnel syndrome (CTS) was made based on clinical findings and physical examinations. Then, the cross-sectional areas of the participants' median nerves from different levels were measured. Meidolateral and anteroposterior diameter were measured at the level of the carpal tunnel inlet. Flattening ratio was calculated. wrist to forearm ratio and wrist to forearm difference were calculated. The obtained data were compared between RA with CTS, RA without CTS and healthy control.

Irisin Levels in Patients With Charcot-Marie-Tooth (CMT) Disease

Charcot-Marie-Tooth Disease

Irisin is an exercise-mimetic myokine secreted by skeletal muscle. Compelling evidence in animal models and humans showed that Irisin prevents onset of musculoskeletal atrophy and its low serum levels are predictive of sarcopenia. The investigators evaluated the levels of irisin in patients affected by an hereditary motor and sensory neuropathy, namely Charcot-Marie-Tooth disease (CMT), in order to investigate possible key determinants of their muscle quality and possibly prevent the progressive distal weakness and muscle atrophy.

Trial of Bilateral Sagittal Split Osteotomy Induced Paresthesia Using Ultrasonic vs. Reciprocating...

Surgical ComplicationParesthesia8 more

The aim of this prospective study is to analyze the postoperative paresthesias experienced in patients who undergo bilateral sagittal split osteotomies (BSSO) using an ultrasonic saw, versus a reciprocating saw. Patients included in the study are ages 15-45 scheduled to undergo BSSO surgery at the University of California, San Francisco. One side of the patient's mandible will be instrumented with either the Stryker Sonopet ultrasonic saw or traditional reciprocating saw, while the other side will receive the remaining intervention (determined via randomization on the day of surgery). Patient paresthesias will then be analyzed on each side for 3 months postoperatively (at postoperative days: 1, 7, 14, 28, and 84). Sensory examinations will be carried out by blinded examiners using von Frey hairs and two point discrimination testing. Patients will also subjectively rate their sensation on each side. The results will then be analyzed to determine if patient paresthesias, including the severity and duration, differed depending on which instrument was used, the ultrasonic or reciprocating saw.

Nociceptive Processing in Acute Cutaneous Nerve Entrapment Syndrome

Anterior Cutaneous Nerve Entrapment Syndrome (ACNES)

Rationale: Chronic abdominal pain is a frequently occurring condition. Although hardly ever considered, the abdominal wall is the primary cause in 10-30% of cases. Most often it is caused by entrapment of an intercostal nerve in the anterior rectus sheath, the Anterior Cutaneous Nerve Entrapment Syndrome (ACNES). Treatment consists of local anaesthetic injections combined with methyl-prednisolon. When ineffective, a neurectomy at the site of penetration out of the ventral rectus sheet should be considered. This neurectomy however is effective in 73% of cases, leaving some 25% of patients in pain. Whether these refractory ACNES patients suffer from underlying pathologic pain disorders is subject to investigation, by using quantitative sensory testing (QST). Objective: To investigate nociceptive processing and possible underlying pathological pain processing mechanisms in ACNES patients. Study design: An observational case-control study. Study population: Patients treated for ACNES (n = 50) compared to healthy controls from an existing database. Measurements: Quantitative sensory testing (QST) of nociception, performed after treatment of ACNES for both successfully treated and refractory patients in comparison to healthy controls. Visual Analogue Scores (VAS) measured before, during and after testing procedures. Pain Anxiety Symptom Scale (PASS) and Pain Catastrophizing Scale (PCS) questionnaires. Main study parameters: Pressure pain and electrical pain thresholds as investigated by QST. Secondary study parameters are VAS-scores and results of PASS and PCS questionnaires.
