  • Neuromuscular disorders are common causes of weakness and hypotonia in the infantile period and in childhood. Accurate diagnosis of specific neuromuscular disorders depends first on identification of which aspect of the peripheral neuromuscular system is affected-the motor neuron in the spinal cord, the nerve root or peripheral nerve, the neuromuscular junction, or the muscle-and then on the determination of the etiology and specific clinical entity. Spinal muscular atrophy(SMA) is the most common autosomal-recessive genetic disorder lethal to infants. The three major childhood-onset forms of SMA are now usually called type I, type II and typeⅢ. Progression of the disease is due to loss of anterior horn cells, thought to be caused by apoptosis. Diagnosis is based on the course of the illness, as well as certain changes seen on nerve and muscle biopsy and electrodiagnostic studies. More recently, our understanding of the genetics of this disorder has provided a noninvasive approach to diagnosis. We report on a 3-year-old male patient with spinal muscular atrophy type II. He had progressive muscular weakness since 18 months of age. The upper arms were slightly, and the thighs moderately atrophic. There was muscle weakness of both the upper and lower limbs, being more proximal in distribution. Electromyogram revealed a neurogenic pattern.

  • Spinal Muscular Atrophy(SMA) is characterized by degeneration of the anterior horn cells leading to symmetrical muscle weakness and wasting of voluntary muscles. Depending on the age of onset, the maximum muscular activity achieved, and survivorship, 3 types of SMA are recognized: SMA type I=Werdnig-Hoffman disease; SMA type II=an intermediate form; SMA type III = Wohlfart-Kugelberg-Welander disease. We report on a 10-month-old male patient with SMA type II complained cough and sputum. We treated with Bopejungchungtang for his cough and sputum. After administration of Bopejunchungtang cough and sputum decreased and almost disappeared.

  • The objective of this study was to review the clinical characteristics of patients with spinal muscular atrophy and to emphasize the importance of performing genetic mutational analysis at initial patient assessment. This is a single center oriented, retrospective, and descriptive study conducted in Seoul, South Korea. Genetic mutational analysis to detect the deletion of exon 7 of the SMN1 gene on chromosome 5q13 was performed by multiplex ligation-dependent probe amplification. Clinical features, electrodiagnostic study results, muscle biopsy results, and laboratory test results were reviewed from patient medical records. Of all 28 patients (15 males and 13 females), all showed bilateral symmetric proximal dominant weakness. Among them, 3 patients were classified as type I, 14 patients as type II, and 11 patients as type III. Twenty-five patients had scoliosis and eight of these patients received surgical treatment for scoliosis with improvement in clinical outcomes. Ventilator support was used in 15 patients. In terms of the diagnostic process, 15 patients had completed an electrodiagnostic study and muscle biopsy before genetic testing, and six of these patients were initially misdiagnosed with myopathy. Owing to the similar clinical features of SMA and congenital myopathy, an electrodiagnostic study and muscle biopsy could create confusion in the correct diagnosis in some cases. Therefore, it is recommended that genetic mutation analysis should be conducted along with an electrodiagnostic study or muscle biopsy in the diagnostic process for spinal muscular atrophy.

  • Numerous biochemical molecules have been implicated in the development of muscular atrophy. However, control mechanisms associated with muscular disease are not clear. The present study was conducted to investigate gene expression profiles of rat muscle during the denervation to atrophy transition processes. We isolated total RNA from rats suffering from partial muscle atrophy (P) and electromyostimulated atrophy (PE) and synthesized cDNA using annealing control primers. Using 20 ACPs for PCR, we cloned 18 DEGs using TOPO TA cloning vector, sequenced, and analyzed their identities using BLAST search. Sequences of 14 clones significantly matched database entries, while one clone was ESTs, and 3 clones were unidentified. Different expression profiles of selected DEGs between P and PE were confirmed. The troponin T, Fkbp1a, RGD1307554, Phtf1, Atp1a1 and Commd3 were highly expressed genes in the P and PE groups, while Krox-25 and TCOX2 were only expressed genes in the P group, the Sv2b and Marcks were only expressed genes in PE group. also, Cox8h was highly expressed genes in PE groups. The ASPH, ND1, and ARPL1 were highly expressed genes in the P and PE groups. List of genes obtained from the present study might provide an insight for the study of mechanism regulating muscle atrophy and electrostimulated muscle atrophy transitions. These data suggest that troponin T, Fkbp1a, RGD1307554, Phtf1, Atp1a1, and Commd3 are potentially useful as clinical biomarkers of age-related muscle atrophy and dysfunction.

  • 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.

  • Purpose: The purpose of this study was to examine the effects of Cu/Zn SOD on reduction of hindlimb muscular atrophy induced by cisplatin in rats. Methods: Forty-two rats were assigned to three groups; control group, Cisplatin (CDDP) group and cisplatin with Cu/Zn SOD (CDDP-SOD) group. At day 35 hindlimb muscles were dissected. Food intake, activity, withdrawal threshold, muscle weight, and Type I, II fiber cross-sectional area (CSA) of dissected muscles were measured. Relative SOD activity and expression of MHC and phosphorylated Akt, ERK were measured after dissection. Results: Muscle weight and Type I, II fiber CSA of hindlimb muscles in the CDDP group were significantly less than the control group. Muscle weight and Type I, II fiber CSA of hindlimb muscles, food intake, activity, and withdrawal thresholds of the CDDP-SOD group were significantly greater than the CDDP group. There were no significant differences in relative SOD activities of hindlimb muscles between the CDDP-SOD and CDDP groups. MHC expression and phosphorylated Akt, ERK of hindlimb muscles in the CDDP-SOD group were significantly greater than the CDDP group. Conclusion: Cu/Zn SOD attenuates hindlimb muscular atrophy induced by cisplatin through increased food intake and activity. Increment of phosphorylated Akt, ERK may relate to attenuation of hindlimb muscular atrophy.

  • Spinal muscular atrophy (SMA) is the second most common fatal disease of childhood with autosomal dominant mode of inheritance, and in its less severe form the third most common neuromuscular disease of childhood after Duchenne muscular dystrophy. The genetic defect was found to be on the long arm of chromosome 5 (5q11.2-q13.3) where many genes and microsatellite markers were missing. One of the most important genes is the Survival Motor Neuron (SMN) gene which is homozygously missing in 90% of SMA patients. Another important gene, the Neuronal Apoptosis Inhibitory Protein (NAIP) gene was found to be defective in 67% of SMA type I patients. Studies so far suggest SMA occurs when the genes on the long arm of chromosome 5 are mutated or deleted. Recently our hospital encountered 2 SMA patients of type I and II respectively. These patients both had homozygously defective SMN genes but intact NAIP genes. We are reporting these cases with bibliographic review and discussion. Korean SMA patients presumably have defects in SMN genes similar to those found in European patients, although the significance of NAIP genes remains to be established. SMN gene defects can be easily diagnosed using PCR and restriction enzymes, and this method could be applied towards convenient prenatal diagnosis and towards screening for family members at risk.

  • Objectives: Studies involving patients with spinobulbar muscular atrophy (SBMA), which is often referred to as Kennedy's disease, similar to those involving patients with progressive muscular disease (PMD), are rare. This paper reports a case study involving the use of Korean medicine to treat a patient with SBMA. Methods: We treated a patient with SBMA with unique symptoms by using various kinds of pharmacopuncture and herbal medicines for about two and a half years. After the treatment had ended, we evaluated the patient's conditions and the side effects of the treatment. Results: After treatment, the patient's symptoms were stabilized, and the patient suffered no abnormalities or side effects. No special changes in condition were noted during treatment period, and the patient was very satisfied with his response to treatment. Conclusion: Existing treatments have some considerable after effects and are difficult to apply in domestic clinics. In this regard, our findings should open possibilities for new clinical guidelines. Nevertheless, the limitations associated with this case study should be resolved, and more studies need to be conducted.

  • Intercostal nerve injury is known to occur during thoracotomy; however, rectus abdominis muscle atrophy has rarely been reported. We describe a 52-year-old man who underwent primary closure of esophageal perforation and lung decortication via left thoracotomy. He was discharged 40 days postoperatively without any complications. He noticed an abdominal bulge 2 months later, and computed tomography revealed left rectus abdominis muscle atrophy. We report thoracotomy induced denervation causing rectus abdominis muscle atrophy.
