RESUMEN
BACKGROUND - Peripheral neuropathies are the most common neuromuscular disorder seen by neurologists. Nerve ultrasonography is a recently emerging tool for visualizing the structure, architecture and vascularity of peripheral nerves. OBJECTIVES -To study the Clinical correlation between Nerve conduction studies and Neurosonography in peripheral neuropathies. METHODOLOGY - All patients with peripheral neuropathy were included in the study from February 2016 to January 2018. RESULTS -The most common aetiologies for peripheral neuropathy were diabetes and leprosy. Nerve ultrasound showed corresponding changes in the above conditions. CONCLUSION – Nerve ultrasound is useful in peripheral neuropathy and can complement other diagnostic investigations.
RESUMEN
Objective To explore the clinical and pathological features of leprous neuritis.Methods Sural nerve biopsied specimens from one patient with leprous neuritis were analyzed with histopathology and electron microscopy.Results The main clinical characteristics included injuries of sensory nerves with numbness and pain in the distal limbs, vegetative nerve functional disturbance, and the asymmetrical bulky ulnar nerve. The pathological changes were the presence of lymphocytic infiltrates in the endoneurial and epineurial spaces, a mild stenosis of small vessel with a large number of perivascular lymphocytic and mononuclear phagocytic infiltrates combined with epithelioid cells form. Anti-acid staining demonstrated the positive leprosy bacillus in nerve fibers. A nearly completely loss of myelinated fibers and obvious connective tissue proliferation were also seen in the sural nerve. The electron microscopy observed marked axonal degeneration of unmyelinated nerve fibers with many leprosy bacillus in Schwann' cells. This case was treated with Aminophenylsulfone and Dehydrocortisone for one year and his condition had improved.Conclusions Diagnosis of leprous neuritis depends on the nerve biopsy, and the early treatment may relieve disability.
