High ultrasound variability in chronic immune-mediated neuropathies. Review of the literature and personal observations

Chronic immune-mediated neuropathies show high clinical variability. Diagnosis is based on clinical and neurophysiological studies, but recently ultrasound (US) of peripheral nerves has been shown to provide useful morphological information. US has already been shown to crucially influence diagnosis and clinical care in entrapment neuropathies, in traumatic nerve lesions and in tumors. The role of US in the evaluation of polyneuropathies is still not clearly defined, but increasing attention has recently been focused on the immune-mediated neuropathies and specific US measures (namely the intra- and inter-nerve cross-sectional area variability) have been developed. The aim of the current paper is to make a review of the available nerve US studies and provide data from personal observations in the most common chronic immune-mediated neuropathies.     

Ultrasound diagnosis of bony nerve entrapment: Case series and literature review

Introduction: Nerve entrapment due to osseous callus formation is a rare complication after bone fracture. Electrodiagnostic studies and routine radiographic imaging often fail to demonstrate the pathology. The diagnosis is difficult and is often made incidentally upon surgical exploration. Nerve ultrasonography has not been used routinely to assess such lesions. Methods: We report 5 cases of nerve entrapment in osseous callus after fractures that occurred in 2011 and 2012. The diagnosis was made by ultrasound (US). We then performed a review of the relevant literature. Conclusions: US is becoming an invaluable tool for diagnosing peripheral nerve entrapments. The current cases suggest that nerve US should be strongly considered as an adjunctive diagnostic tool for nerve palsies developing after trauma. Muscle Nerve 48 : 445–450, 2013

COPD immunopathology

The immunopathology of chronic obstructive pulmonary disease (COPD) is based on the innate and adaptive inflammatory immune responses to the chronic inhalation of cigarette smoking. In the last quarter of the century, the analysis of specimens obtained from the lower airways of COPD patients compared with those from a control group of age-matched smokers with normal lung function has provided novel insights on the potential pathogenetic role of the different cells of the innate and acquired immune responses and their pro/anti-inflammatory mediators and intracellular signalling pathways, contributing to a better knowledge of the immunopathology of COPD both during its stable phase and during its exacerbations. This also has provided a scientific rationale for new drugs discovery and targeting to the lower airways. This review summarises and discusses the immunopathology of COPD patients, of different severity, compared with control smokers with normal lung function.     

Reaching the covert, fragile side of patients: the case of narcissistic personality disorder

A multifaceted self allows selection of those sides that are most suited to a situation and an interpersonal context, thus improving adaptation. Patients suffering from personality disorders display a limited range of self-aspects, and their relationships are stereotyped and maladaptive. Another problem is that some of these sides scarcely reach consciousness and usually remain in the background. In the case of narcissistic personality disorder (NPD) the self-part that is fragile is unlikely to reach consciousness, so that people suffering from this disorder are impervious and detached. We present a case of a psychotherapist working with a woman suffering from NPD by facilitating the emergence of the fragile part of her self, hidden by angry and scornful characters. We demonstrate, moreover, how reaching such a self-part is associated with an improvement in the patient's interpersonal relationships outside the consulting room.     

Telemedicine for Facio-Scapulo-Humeral Muscular Dystrophy: A multidisciplinary approach to improve quality of life and reduce hospitalization rate?

Background

Facio-Scapulo-Humeral Muscular Dystrophy (FSHD) is an autosomal dominant inherited disorder characterized by a variable and asymmetric involvement of facial, trunk, upper and lower extremity muscles. Although respiratory weakness is a relatively unknown feature of FSHD, it is not rare. Telemedicine has been used in a variety of health care fields, but only recently, with the advent of sophisticated technology, its interest among health professionals became evident, even in such diseases.

Digital breast tomosynthesis and contrast‐enhanced dual‐energy digital mammography alone and in combination compared to 2D digital synthetized mammography and MR imaging in breast cancer detection and classification

To compare diagnostic performance of contrast‐enhanced dual‐energy digital mammography (CEDM) and digital breast tomosynthesis (DBT) alone and in combination compared to 2D digital mammography (MX) and dynamic contrast‐enhanced MRI (DCE‐MRI) in women with breast lesions. We enrolled 100 consecutive patients with breast lesions (BIRADS 3‐5 at imaging or clinically suspicious). CEDM, DBT, and DCE‐MRI 2D were acquired. Synthetized MX was obtained by DBT. A total of 134 lesions were investigated on 111 breasts of 100 enrolled patients: 53 were histopathologically proven as benign and 81 as malignant. Nonparametric statistics and receiver operating characteristic (ROC) curve were performed. Two‐dimensional synthetized MX showed an area under ROC curve (AUC) of 0.764 (sensitivity 65%, specificity 80%), while AUC was of 0.845 (sensitivity 80%, specificity 82%) for DBT, of 0.879 (sensitivity 82%, specificity 80%) for CEDM, and of 0.892 (sensitivity 91%, specificity 84%) for CE‐MRI. DCE‐MRI determined an AUC of 0.934 (sensitivity 96%, specificity 88%). Combined CEDM with DBT findings, we obtained an AUC of 0.890 (sensitivity 89%, specificity 74%). A difference statistically significant was observed only between DCE‐MRI and CEDM (P = .03). DBT, CEDM, CEDM combined to tomosynthesis, and DCE‐MRI had a high ability to identify multifocal and bilateral lesions with a detection rate of 77%, 85%, 91%, and 95% respectively, while 2D synthetized MX had a detection rate for multifocal lesions of 56%. DBT and CEDM have superior diagnostic accuracy of 2D synthetized MX to identify and classify breast lesions, and CEDM combined with DBT has better diagnostic performance compared with DBT alone. The best results in terms of diagnostic performance were obtained by DCE‐MRI. Dynamic information obtained by time‐intensity curve including entire phase of contrast agent uptake allows a better detection and classification of breast lesions.
