  • Some patients with leprosy may present with atypical features, such as isolated peripheral neuropathy without skin lesions, or marked proprioceptive dysfunction. We report a 56-year-old female who presented with predominant proprioceptive loss without skin lesion, but was finally confirmed as leprous neuropathy by sural nerve biopsy. It is postulated that large myelinated fibers were affected by chronic immunological reactions triggered by inactive bacterial particles, producing a peripheral neuropathy presenting as predominant proprioceptive sensory loss without typical skin lesions.

  • The purpose of this study was to review the limb apraxia. It includes the evaluation and neurophysiological aspects for limb apraxia. Limb apraxia comprised a wide spectrum of higher-order motor disorders that results from acquired brain disease affecting the performance of skilled and/or learned movements with the forelimbs and is a common sequela of left brain damage that consists of a deficit in performing gestures to verbal command or to imitation. There are two forms in limb apraxia; ideational apraxia and ideomotor apraxia. A assessment of limb apraxia typically includes pantomiming and imitation of transitive, intransitive, and meaningless gestures. Limb apraxia has been attributed to damage confined to the cerebral cortex, cortico-cortical connecting pathways, and basal ganglia.

  • Licorice is widely used as a Chinese(herbal) medicine. The glycyrrhizin, a main ingredient of the natural licorice, has a potent mineralocorticoid effect which may cause severe hypokalemia and muscle paralysis. We present a 60-year-old woman, who had been ingesting one or two spoonful of licorice powder daily for about one year, developed acute flaccid quadriparesis with high levels of serum muscle enzymes and the typical features of mineralocorticoid excess such as severe hypokalemia and metabolic alkalosis. Both plasma renin activity and serum aldosterone level were below the normal values. This case indicates that licorice-induced hypokalemic myopathy should be considered in the differential diagnosis of a patient with acute quadriparesis and hypokalemia.

  • Anorexia nervosa(AN) is a disorder characterized by disturbance of body image, fear of gaining weight, severe weight loss and, in female, amenorrhea. Compared with normal persons, patients with AN have neuropathic symptoms more frequently. But electrophysiologic abnormalities have rarely been reported. We experienced a case with recurrent neuropathic symptoms after severe weight loss. Further evaluation revealed AN. Electrophysiologic study showed sensorimotor polyneuropathy and focal neuropathy with conduction block. As far as we know, this feature of neuropathy in AN has not been described. We describe unusual feature of neuropathy in our patient with literature review.

  • Lateral antabrachial cutaneous neuropathy(LACN) was diagnosed in a 42-year-old woman who developed pain and paresthesia in the left forearm after several days of heavy labor. The symptoms were resolved with conservative treatment, including cessation of heavy labor and a brief course of oral corticosteroids. But the symptoms recurred after 9 months. Those were also resolved with same treatment as the first attack. LACN is important to recognize because the symptoms may mimic the pathology of a cervical root, the brachial plexus, the radial and median nerves at the level of the elbow, and a focal idiopathic inflammatory neuritis.

  • The distal myopathies(DM) are clinically defined as inherited or sporadic primary muscle disorders characterized by progressive muscular weakness and atrophy beginning in the hands or feet and pathologically by myopathic changes in skeletal muscles. The pathologic changes are somewhat similar to those seen in chronic muscular dystrophy, but necrotic and regenerative processes are less prominent and creatine kinase levels are either normal or only mildly elevated. The most representative diseases are dominantly inherited Welander distal myopathy and tibial muscular dystrophy, and the recessively inherited distal myopathy with rimmed vacuoles and distal muscular dystrophy(Miyoshi myopathy). At present, further study is necessary to determine why rimmed vacuoles are so common in the DM, and what role they play in the pathogenesis of muscle fiber atrophy and loss, predominantly in the distal portions of the extremities.

  • Diabetic polyneuropathy (DPN) is the most common form of diabetic neuropathy, and causes a significant morbidity with an impact on the quality of life in the patients with diabetes. Since DPN frequently induces foot deformity and ulceration, which finally leads to foot amputation, the early detection and treatment is very important for the prevention of a permanent structural change. In the early stage of DPN, the diagnostic methods which can evaluate the function or structure of small nerve fibers should be employed because small nerve fibers are first involved in the course of DPN. However, the nerve conduction study cannot reflect the function of the small nerve fibers, and thus, has a definite limitation in the early diagnosis of DPN. For the early detection of DPN, electrodiagnostic data should be interpreted on a clinical context, along with the careful evaluation of the small nerve fiber functions using the tests such as the analysis of intraepidermal nerve fiber density.

  • Colchicine is widely used in the treatment of gouty arthritis, and chronic use of colchicine can cause vacuolar myopathy. We report colchicine-induced myopathy with electrophysiological myotonia in a patient with gouty arthritis. A 86-year-old man with gouty arthritis presented with progressive proximal weakness and gait disturbance. Electrophysiological finding showed myotonic myopathy and muscle biopsy revealed a vacuolar myopathy. His symptoms soon resolved with the discontinuation of colchicine.

  • Miyoshi myopathy (MM) is caused by the mutations of dysferlin gene (DYSF), which impairs the function of dysferlin protein causing muscle membrane dysfunction. We report a patient showing the MM phenotype who has a sister with LGMD 2B phenotype, along with the results of the immunohistochemical and molecular analyses of the DYSF gene. Immunohistochemical analysis noted negative immunoreactivity against dysferlin. Direct DNA sequencing of whole exons of DYSF gene revealed heterozygous nonsense mutations (c.610C>T + c.2494C>T). To our knowledge, this is the first reported MM case with this very combination of heterozygous mutations.
