Less specific arm illnesses

The mind and the hand

Symptoms are determined in large part by mindsets. Feelings of distress and unhelpful thoughts (misinterpretations) of symptoms account for much of the variability in comfort and capability with the severity of the underlying pathophysiology making a more limited contribution. Incorporating this experimental evidence into the daily practice of hand surgery will help us find ways to develop healthy mindsets, to prioritize the alleviation of distress and the gentle redirection of unhelpful thoughts, to avoid unnecessary surgery, and to provide better psychological and social support for people recovering from injury and surgery.

Thoracic outlet syndrome: a review

Thoracic outlet syndrome (TOS) is a rare condition (1-3 per 100,000) caused by neurovascular compression at the thoracic outlet and presents with arm pain and swelling, arm fatigue, paresthesias, weakness, and discoloration of the hand. TOS can be classified as neurogenic, arterial, or venous based on the compressed structure(s). Patients develop TOS secondary to congenital abnormalities such as cervical ribs or fibrous bands originating from a cervical rib leading to an objectively verifiable form of TOS. However, the diagnosis of TOS is often made in the presence of symptoms with physical examination findings (disputed TOS). TOS is not a diagnosis of exclusion, and there should be evidence for a physical anomaly that can be corrected. In patients with an identifiable narrowing of the thoracic outlet and/or symptoms with a high probability of thoracic outlet neurovascular compression, diagnosis of TOS can be established through history, a physical examination maneuvers, and imaging. Neck trauma or repeated work stress can cause scalene muscle scaring or dislodging of a congenital cervical rib that can compress the brachial plexus. Nonsurgical treatment includes anti-inflammatory medication, weight loss, physical therapy/strengthening exercises, and botulinum toxin injections. The most common surgical treatments include brachial plexus decompression, neurolysis, and scalenotomy with or without first rib resection. Patients undergoing surgical treatment for TOS should be seen postoperatively to begin passive/assisted mobilization of the shoulder. By 8 weeks postoperatively, patients can begin resistance strength training. Surgical treatment complications include injury to the subclavian vessels potentially leading to exsanguination and death, brachial plexus injury, hemothorax, and pneumothorax. In this review, we outline the diagnostic tests and treatment options for TOS to better guide clinicians in recognizing and treating vascular TOS and objectively verifiable forms of neurogenic TOS.

Severe and enduring somatoform disorders: recognition and management

Patients with severe and enduring somatoform disorders (SESD) characteristically present with multiple, recurrent and frequently changing physical symptoms that have usually been present for several years before referral to a psychiatrist/psychologist. Many patients report long histories of contact with both primary and tertiary care services, have undergone repeated fruitless investigations and have high levels of disability. SESD are responsible for disproportionately high healthcare costs and are the third most common cause of workplace absence. Identification of patients with SESD by psychiatrists requires particular skills: collaboration with colleagues is vital and there are risks of iatrogenic harm. We describe the obstacles encountered in identifying these patients as well as methods of assessment and management. Treatment pathways best suited to managing this large and as yet untended group of patients are described.

Opioid Use, Satisfaction, and Pain Intensity After Orthopedic Surgery

BACKGROUND

Patients in other countries use fewer opioids than patients in the United States with satisfactory pain relief.

OBJECTIVE

This study tested the null hypothesis that opioid intake after orthopedic surgery does not influence satisfaction with pain management.

METHODS

A total of 232 orthopedic surgical inpatients completed measures of pain self-efficacy and symptoms of depression at enrollment and commonly used measures of pain intensity, satisfaction with pain relief, and satisfaction with hospital staff attention to pain approximately 14 days after surgery. Inpatient opioid intake per 24-hour period was quantified.

RESULTS

At a phone evaluation approximately 2 weeks after discharge from the hospital, patients who were always satisfied with their pain relief in hospital and always satisfied with staff attention to pain used significantly less opioids on day 1 compared with patients who were not always satisfied. There were no differences in satisfaction by type of surgery. The final multivariable model for not always satisfied with pain relief included greater opioid use on day 1 (odds ratio = 1.2), and preadmission diagnosis of depression (odds ratio = 2.6). Greater opioid use on day 1 was the only factor associated with less than always satisfied with the staff attention to pain relief (odds ratio = 1.3).

CONCLUSIONS

Patients who take more opioids report less satisfaction with pain relief and greater pain intensity. Evidence-based interventions to increase self-efficacy merit additional study for the management of postoperative pain.

Factitious disorders and malingering: challenges for clinical assessment and management

Compared with other psychiatric disorders, diagnosis of factitious disorders is rare, with identification largely dependent on the systematic collection of relevant information, including a detailed chronology and scrutiny of the patient's medical record. Management of such disorders ideally requires a team-based approach and close involvement of the primary care doctor. As deception is a key defining component of factitious disorders, diagnosis has important implications for young children, particularly when identified in women and health-care workers. Malingering is considered to be rare in clinical practice, whereas simulation of symptoms, motivated by financial rewards, is regarded as more common in medicolegal settings. Although psychometric investigations (eg, symptom validity testing) can inform the detection of illness deception, such tests need support from converging evidence sources, including detailed interview assessments, medical notes, and relevant non-medical investigations. A key challenge in any discussion of abnormal health-care-seeking behaviour is the extent to which a person's reported symptoms are considered to be a product of choice, or psychopathology beyond volitional control, or perhaps both. Clinical skills alone are not typically sufficient for diagnosis or to detect malingering. Medical education needs to provide doctors with the conceptual, developmental, and management frameworks to understand and deal with patients whose symptoms appear to be simulated. Central to the understanding of factitious disorders and malingering are the explanatory models and beliefs used to provide meaning for both patients and doctors. Future progress in management will benefit from an increased appreciation of the contribution of non-medical factors and a greater awareness of the conceptual and clinical findings from social neuroscience, occupational health, and clinical psychology.
