Two cases of segmental sporadic schwannomatosis characterized by unusual location of multiple schwannomas in digital nerves (case 1) and the superficial radial nerve (case 2) are described in this paper. In the first of the described cases, 6 tumours located at the base of the middle finger and in its distal portion were excised from both digital nerves. In the second case, 3 tumours located in...

OBJECTIVE To evaluate each digital branch of the median sensory nerve and motor nerves to abductor pollicis brevis (APB) and 2nd lumbrical (2L) according to the severity of carpal tunnel syndrome (CTS). METHODS A prospective study was performed in 67 hands of 41 patients with CTS consisting of mild, 23; moderate, 27; and severe cases, 17. Compound muscle action potentials (CMAPs) were obtaine...

The cortical representations of the hand in area 3b in adult owl monkeys were defined with use of microelectrode mapping techniques 2-8 months after surgical amputation of digit 3, or of both digits 2 and 3. Digital nerves were tied to prevent their regeneration within the amputation stump. Successive maps were derived in several monkeys to determine the nature of changes in map organization in...

Numbness within the thumb involving palmar aspect with three and a half digits as division is common presentation of peripheral nerve injury. However, it rarely observed to be presented numbness at ulnar-palmar side thumb, where longitudinal melanonychia on nail plate acts division. We present case that reveals concurrence suffered from injury during course occupational therapy.

Eighty percent of 50 dissected cadaver palms showed a communicating branch between the fourth and third common digital nerves (ulnar and median origins, respectively). The branch commonly crossed the palm with the superficial arterial arch and usually provided sensory fibers from a branch of the superficial ulnar nerve into the ring finger radial digital nerve. Caution should be taken during ca...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016216050 DESCRIPTION A 68-year-old African-American man with a history of duodenal adenocarcinoma was found to have innumerable 1 mm hyperkeratotic depressions along his palmar creases bilaterally (figures 1–3). The patient reported having these lesions since early in childhood. ...

Normal tendons, normal palmar aponeuroses and specimens from patients with Dupuytren's disease, namely apparently normal palmar aponeuroses and contracture bands were subjected to elastase and chondroitinase ABC digestion. Maximum Young's modulus, normalized hysteresis loop and residual elongation were determined before and after enzyme treatment. In normal tendons, normal and apparently normal...

INTRODUCTION The pathogenesis of circumscribed palmar hypokeratosis (CPH) is still controversial, and to date there is no treatment of choice. METHODS We report on a patient with CPH responding to treatment with fluorouracil cream. RESULTS The clinical course and histopathological features in our observation point towards the possibility of an underlying squamous cell carcinoma in situ pres...

conclusions obtained results demonstrate significant differences between intraneural and perineural injection pressures in the median, ulnar, and radial nerves. intraneural injection pressures show low specificity but high sensitivity suggesting that pressure monitoring might be a valuable tool in improving the safety and efficacy of peripheral nerve blockade in regional anesthesia. peripheral ...

A 7-year-old boy presented with acute-onset headache, vomiting, and confusion during summer. Two months previously, he developed right thigh pain, causing intermittent limping. Three days before admission, headache; 1 day later, experienced fatigue, nausea, vomiting. On the of presentation, symptoms included behavioral change (showered 15 times), unsteadiness, new palmoplantar rash. He lethargy...
