The spectrum of clinical and electrophysiological features in hereditary neuropathy with liability to pressure palsies (HNPP) is broad. We analyze a series of Brazilian patients with HNPP. Correlations between clinical manifestations, laboratory features, electrophysiological analyze, histological and molecular findings were done. In five cases, more than one episode occurred before diagnosis. Median nerve in the carpal tunnel at the wrist, ulnar nerve in its groove at the elbow, fibular nerve in the head of the fibula at the knee, radial nerve in its groove of the humerus and suprascapular nerve in its notch at the supraspinous fossa were found as focal neuropathies...

BACKGROUND: Neurologic lesions are relatively common after total shoulder arthroplasty. These injuries are mostly due to traction. We aimed to identify the arm manipulations and steps during reverse total shoulder arthroplasty (RTSA) that affect nerve stress. METHODS: Stress was measured in 10 shoulders of 5 cadavers by use of a tensiometer on each nerve from the brachial plexus, with shoulders in different arm positions and during different surgical steps of RTSA...

OBJECTIVES: To investigate the feasibility of diffusion-weighted magnetic resonance neurography (DW-MRN) in the visualisation of extremity nerves in the wrist and palm. METHODS: Thirty-two volunteers and 21 patients underwent imaging of the wrist and palm on a 3-T MR scanner. In all subjects, two radiologists evaluated the image quality on DW-MRN using a four-point grading scale. Kappa statistics were obtained for inter-observer performance. In volunteers, the chi-squared test was used to assess the differences in nerve visualisation on DW-MRN and axial fat-suppressed proton density weighted imaging (FS-PDWI)...

Chondroepitrochlearis (CET) is an anomalous muscular slip that originates from the pectoralis major muscle and inserts into epicondyle of the humerus. The morphology of this variant form of pectoralis major can vary from slender to strong musculo-tendinous. In its course, it usually crosses the neurovascular structures of arm; their compression is a major complication that could be manifested by its persistence. In the present case, potentially anomalous CET muscle with the slender slip of origin, but strong tendinous insertion to the medial epicondyle of the humerus was found unilaterally...

BACKGROUND: Cardiovascular procedures are common and are trending toward endovascular interventions. With this increase in endovascular procedures, there is also increasing awareness of upper extremity morbidity resulting from treatment. METHODS: Articles indexed within PubMed between the years 1975 and 2015 that discussed such complications were reviewed. RESULTS: Percutaneous radial artery access can lead to nerve ischemia, especially in the setting of an incomplete arterial arch, whereas radial artery harvesting for bypass surgery more commonly causes frank tissue ischemia and radial neuropathy...

Introduction We aimed to identify prognostic factors in ulnar neuropathy at the elbow (UNE) and developed a scoring system to predict the prognosis. Methods We collected baseline clinical, electrophysiological, and ultrasonographical data from 2 cohorts. The outcome for all patients were determined on follow up. Prognostic factors were determined using single and multiple variable analyses. A points system was developed to determine the risk for an unfavorable outcome. Results Of 220 patients with UNE 178 (81%) could be re-evaluated...

PURPOSE: To prove that the relationship between sensory latencies and amplitudes is useful in determining the severity of neuropathies. This is achieved by deriving a mathematical relationship between sensory distal latency and amplitude. Determine whether sensory amplitudes below predicted correlate with a worse pathology. PROCEDURES: Patients seen for Nerve Conduction Studies by the Department of Physical Medicine and Rehabilitation at Cooper University Hospital between 12/1/12 and 12/31/14 were invited to participate in a prospective database...

INTRODUCTION: Leprosy is an infectious disease caused by the bacteria Mycobacterium leprae. It is particularly prone to affect the skin and the nerve trunks and, in fact, both are compromised in most infected patients. It is transmitted by exposure to those with the disease and sometimes by reactivation. One uncommon possibility is pure neural leprosy, which is characterised by neuropathy, but without skin lesions. We report the case of a patient with pure neural leprosy and review the diagnostic aspects...

Bowler's thumb is a rare traumatic neuropathy of the ulnar digital nerve of the thumb. We present a case of bowler's thumb in a 21-year-old male recreational bowler who presented with a painful mass on the ulnar side of the right thumb. Magnetic resonance (MR) imaging of the hand was inconclusive. However, subsequent ultrasound (US) showed asymmetric enlargement of the ulnar digital nerve of the thumb with marked epineural thickening corresponding to the palpable mass, confirming the clinical diagnosis of bowler's thumb...

BACKGROUND: Ulnar neuropathy at the elbow (UNE) is the second most common mononeuropathy of the upper extremity. One rare cause of UNE is nerve mass lesions, including intraneural ganglion cysts (IGCs). IGC imaging studies provide important information that may determine the nature of a peripheral nerve mass lesion. CASE DESCRIPTION: We present the case of a 73-year-old woman who presented with rapid deterioration of left hand function over 2 months with weakness of fine motor control, grip strength, and dysesthesia in the ulnar nerve distribution...

INTRODUCTION: Differentiating multifocal motor neuropathy (MMN) from amyotrophic lateral sclerosis (ALS) is important, as MMN is a difficult, but treatable disorder. METHODS: We studied peripheral nerve imaging techniques in differentiating MMN from ALS by measuring the cross-sectional area (CSA) of the median and ulnar nerves in the forearms using high resolution ultrasound (HRUS) and MRI. RESULTS: HRUS CSA values of the median nerve in the forearm (P = 0...

A 73-year-old woman who had hypertension developed a slight fever and general malaise with laboratory-proven hepatic dysfunction as well as frequent syncopal attacks 3 months before admission to our hospital. One month later, she developed urinary retention and distal limb numbness. Upon admission, her neurological examination showed reduced limb tendon reflexes, glove and stocking-type numbness, and diminished senses of touch, temperature, pain, and distal leg vibration and position. Serum cytomegalovirus (CMV) IgM antibody and CMV IgG antibody were elevated on admission, and both decreased thereafter, confirming CMV infection...

OBJECTIVE: To identify the factors that could predict the functional outcome in patients with the axonal type of Guillain-Barre syndrome (GBS). METHODS: Two hundred and two GBS patients admitted to our university hospital between 2003 and 2014 were reviewed retrospectively. We defined a good outcome as being "able to walk independently at 1 month after onset" and a poor outcome as being "unable to walk independently at 1 month after onset". We evaluated the factors that differed between the good and poor outcome groups...

OBJECTIVE: The diagnosis of leprous neuropathy is mostly empirical and electrophysiological studies may not truly represent the clinical findings. This study comprehensively evaluates the neuroelectrophysiology and looks at clinico-electrophysiological dissociation. METHODS: Conventional electrophysiological recording included evaluation of median, ulnar, radial, tibial, and common peroneal nerve; an extended protocol included great auricular, phrenic, and facial nerves, along with sympathetic skin response and blink reflex...

OBJECTIVE: Postures and work-hobby activities may play a role in the origin and progression of ulnar neuropathy at the elbow (UNE), whose occurrence appears to be increasing. The time spent on mobile-phone has increased in the last decades leading to an increased time spent with flexed elbow (prolonged-phone-posture, PPP). We aimed to assess the effect of PPP both in patients with symptoms of UNE and in symptom-free subjects. METHODS: Patients with pure sensory symptoms of UNE and negative neurophysiological tests (MIN-UNE) and symptom-free subjects were enrolled...

Objective. The ability to correctly identify chronic demyelinating neuropathy can have important therapeutic and prognostic significance. The stimulus intensity value required to obtain a supramaximal compound muscle action potential amplitude is a commonly acquired data point that has not been formally assessed as a diagnostic tool in routine nerve conduction studies to identify chronic neuropathies. We postulated that this value was significantly elevated in chronic demyelinating neuropathy. Methods. We retrospectively reviewed electrophysiology laboratory records to compare the stimulus intensity values recorded during median and ulnar motor nerve conduction studies...
