  • Late complications of head and neck cancer survivors include neck muscle atrophy and soft-tissue fibrosis. We present an autopsy case of neck muscle atrophy and soft-tissue fibrosis (sternocleidomastoid, omohyoid, digastric, sternohyoid, sternothyroid, and platysma muscles) within the radiation field after modified radical neck dissection type I and postoperative radiotherapy for floor of mouth cancer. A 70-year-old man underwent primary tumor resection of the left floor of mouth, left marginal mandibulectomy, left modified radical neck dissection type I, and reconstruction with a radial forearm free flap. The patient received adjuvant radiotherapy. The dose to the primary tumor bed and involved neck nodes was 63 Gy in 35 fractions over 7 weeks. Areas of subclinical disease (left lower neck) received 50 Gy in 25 fractions over 5 weeks. Adjuvant chemotherapy was not administered.

  • Treatment of hemifacial atrophy is a challenge for oral & maxillofacial surgeons. The surgical approach basically focused on skeletal correction so that the overlying soft tissues can be improved by the osseous change of the skeleton. However, the treatment ends up with insufficient soft tissue mophology in most cases even after skeletal correction. Therefore comprehensive hard and soft tissue reconstruction is needed for treating the hemifacial atrophy. In this case report, we experienced a successful result after combined orthognathic and microvascular adipofascial flap reconstruction for hemifacial atrophy patient.

  • Multiple system atrophy (MSA) is an idiopathic and progressive neurodegenerative disorder. Up to now, treatment of MSA patients had not been reported in Oriental medicine and only rarely reported in Western medicine. We experienced a 75-year-old female diagnosed with MSA and had quadriparesis with dysphagia. She was admitted to the hospital and received herbal medication, acupuncture, moxibustion and rehabilitation therapy. After 2 months, her motor power and swallowing function on video fluoroscopic swallowing test significantly improved. This report shows that Oriental medicine may play a role in the treatment of MSA, and further study is merited.

  • Computerized densitometry was developed or the quantitative measurement of diffuse retinal nerve fiber layer (RNFL) atrophy and intra- and inter-operator reliability and clinical validity of this system were evaluated. Vertical diameter, center of the optic disc, and peripapillary circles which had radii of 1.5 and 2.5 times that of the optic disc were user-interactively determined in digitized RNFL photograph and density profile along each circle was measured and normalized. The areas under the normalized density profiles of the superior and the inferior segments in both circle were used or the study of RNFL. To determine the variability and correspondence in the measurements of density variations, 21 RNFL photographs of glaucoma patients which showed varying degrees of atrophy underwent computerized densitometry by two operators on two separate occasions. Coefficient of variation in the densitometric measurements was $1.2{\sim}5.4%$. Intra- and inter-operator reliabilities were excellent. The correlations between the densitometric values and mean deviations of Humphrey C30-2 visual field showed statistical significance. Computerized densitometry of RNFL photographs was useful in the objective and quantitative assessment of diffuse RNFL atrophy.

  • The potent environmental contaminant, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), induces thymus atrophy in experimental animals. However, its mechanism of action is not fully understood. To gain insight into its immunosuppressive effect, Balb/c mice were intraperitoneally injected with TCDD ($30{\mu}g/kg$ body weight) and genes regulated by TCDD were identified using cDNA arrays [Park and Lee (2002)]. One of the regulated genes was that for plasma glutathione peroxidase (pGPx). Upon TCDD injection, pGPx mRNA levels in the thymus increased, in parallel with increases in GPx activity and the frequency of anti-human pGPx antibody-reactive cells. pGPX mRNA levels were also moderately up-regulated in the testis and spleen. This is the first report that a particular isotype of the glutathione peroxidase family is regulated by TCDD at both mRNA and protein levels. pGPx is expressed in various tissues in contact with body fluids, and detoxifies hydrogen peroxides and lipid hydroperoxides. It will be of interest to assess the role of pGPx in TCDD-induced thymic atrophy.

  • This study reported on the effect of traditional Korean medicine on ataxia, gait disturbance, tremor, and dizziness with cerebellar atrophy. The patient was treated with traditional Korean medicines, such as acupuncture, moxibustion, and herbal medicine (Kuibiondam-tang-gami). The effectiveness of the treatment was evaluated with the scale for the assessment and rating of ataxia (SARA). After treatment, the symptoms had improved. The SARA score decreased by 18 points after Korean medicine treatment. According to this study, traditional Korean medicine can be effective to treat ataxia, gait disturbance, tremor, and dizziness in patients with cerebellar atrophy.

  • Purpose : The present study tested the hypothesis that acupressure at Zusanli(ST36) would attenuate immobilization-induced skeletal muscle atrophy. Methods : The left hind limb was immobilized using casting tape (ST36 group, n=10), and the animals were then treated daily with a pressure needle at ST36. Ten untreated animals with hind limb immobilization and no treatment served as a control group (n=10). After 2 weeks of immobilization, The body weight changes of rats were evaluated and the morphologies of the right and left gastrocnemius muscles in both the ST36 and control groups were assessed by hematoxylin and eosin staining. The levels of malondialdehyde (MDA) of gastrocnemius muscles were observed. Results : The acupressure at the accupoint of Zusanli conferred significant protection against reductions in left gastrocnemius muscle weights and average cross-sectional muscle areas in the ST36 group as compared with those in the control group. Moreover, the acupressure at the ST36 point significantly reduced malondialdehyde (MDA) activity in the gastrocnemius muscles as compared with that in the control group. Conclusion : These results suggest that acupressure at the accupoint of Zusanli provides protection against immobilization-induced muscle atrophy by decreasing MDA activity in gastrocnemius muscles.

  • Many studies on poultry have been conducted in the poultry industry to improve their important economic traits, such as egg production, meat quality, and carcass yield. Environmental changes affect the poultry's economic traits, including muscle growth. The purpose of this study is to investigate the mechanisms by which simvastatin causes muscle injury in quail muscle cells. Following treatment with various doses of simvastatin, LD50 in the quail myoblast cells was determined using a cell viability test; cell death was caused by apoptosis and/or necrosis. Thereafter, the expression patterns of the atrophy marker genes were examined via quantitative reverse-transcription polymerase chain reaction (qRT-PCR). The results showed that the transcriptional levels of the muscle atrophy marker genes (Atrogin-1, TRIM63) and the upstream genes in their signaling cascade were increased by simvastatin treatment. This indicated that simvastatin induced myogenic cell death and muscle injury via protein degradation through muscle atrophy signaling. Further studies should focus on identifying the mechanism by which simvastatin induces the protein degradation signaling pathway in quail muscle..

  • 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.

  • Background and Objectives : This study aimed to determine the clinical effect of $Artecoll^{(R)}$ injection laryngoplasty for patients with vocal atrophy and mild sulcus vocalis. Materials and Method : Forty-one patients with vocal atrophy and/or mild sulcus vocalis received transcutaneous $Artecoll^{(R)}$ injection into the vocal folds under local anesthesia. Subjective evaluations including voice handicap index (VHI) and perceptual grading with Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) scales and objective evaluations including jitter, shimmer, noise-to-harmonic ratio (NHR), speaking fundamental frequency (SFF) and maximum phonation time (MPT) were evaluated before and 3 months after the injection. Results : VHI and Grade, Breathiness and Strain scales in GRBAS showed significant improvement 3 months after injection. SFF and MPT also significantly improved after the injection ; MPT increased and SFF in male patients decreased. Conclusion : Injection laryngoplasty with $Artecoll^{(R)}$ is an effective method for correcting the glottal insufficiency and improving voice quality in patients with vocal atrophy and/or mild sulcus.
