A 12-year-old castrated Toy Poodle was referred with a continuous non-weight bearing lameness of right hind limb due to a traffic accident 9 years ago. Physical examination and radiographs revealed partial loss of right calcaneal bone, loss of Achilles tendon and disused muscular atrophy. Arthrodesis was performed to preserve the function of the right hind limb. Pan tarsal arthrodesis plate was applied medially with 2.7 mm cortical screws and 2.0 mm cortical screws. During fixation, cancellous bone chip was transplanted into the arthrodesis site. A bone union was confirmed 9 weeks after surgery. Furthermore, on the gait analysis, the weight-bearing of right hind limb was restored to 70% of the opposite hind limb. Arthrodesis can be used to treat more difficult and serious problems affecting the joints. In particular, arthrodesis is indicated in cases such as comminuted intraarticular fractures and irreparable injury of the calcaneal tendon apparatus in the hock joint. In this case, the pan tarsal arthrodesis provided stability to the hock joint and improved the gait by restoring severe chronic damage. In conclusion, we successfully treated a challenging disability of hock joint using pan tarsal arthrodesis to restore the legs that were non-weight bearing due to chronic injury by traffic accident and objectively ascertained the increased weight bearing by gait analysis.

청력 장애(hearing loss)는 임상적 및 유전적으로 상당히 이질적인 질병들의 그룹으로, 일반적으로 증후군 유형(syndromic type)과 비증후군 유형(non-syndromic type)으로 구분된다. 상염색체 열성의 청력 장애 환자가 다른 나라들에 비해 파키스탄에서는 상대적으로 흔하게 관찰되는데, 그 원인으로는 빈번한 근친 결혼의 문화가 일부 관여할 것으로 여겨진다. 본 연구는 상염색체 열성의 청력 장애 환자가 있는 두 파키스탄의 근친 가계를 대상으로 전장 엑솜 서열분석(whole exome sequencing)을 실시하여 유전적 원인을 규명하기 위해 수행되었다. 환자의 유전체 분석 결과, 우리는 언어 습득전 발병(prelingual onset)의 청력 장애 가족으로부터 MYO7A 유전자에서 병원성으로 판단되는 동형접합성 돌연변이인 p.Leu326Gln을 분리하였으며, 조기 발병의 청력 장애와 동시에 근위축(muscular atrophy)을 나타내는 환자 가족에서는 병원성이 확실하지 않는 두 변이(variants of uncertain significance)를 GPR98 유전자(p.Val3094Ile)와 PLA2G6 유전자 (p.Asp56Gly)에서 각각 분리하였다. MYO7A 및 PLA2G6 유전자의 missense 돌연변이는 고도로 보존된 단백질 부위에 위치했으며, 인실리코 분석(in silico analysis)에서도 병원성을 예측하였다. 그러나, GPR98 유전자의 돌연변이는 보존성이 다소 낮은 부위에 위치하였으며, 대부분의 인실리코 분석도 비병원성으로 예측했다. 동형접합성 매핑(homozygosity mapping)을 실시하였을 때, 각 가계에서 분리된 동형접합성 돌연변이의 두 대립유전자가 모두 단일 기원에서 유래한 것으로 예측되었는데, 이것은 근친 결혼에 기인한 것으로 판단된다. 본 연구는 파키스탄의 상염색체 열성 청력 장애 환자들의 정확한 분자진단 및 치료에 도움을 줄 수 있을 것으로 기대된다.

The purpose of this study was to determine the effect of intermittent low - intensity, short duration exercise during hindlimb suspension on the mass, relative weight, myofibrillar protein content, cross-sectional area of Type I and Type II fibers and SDH activity in Type II(plantaris) muscle. To examine the effectiveness of intermittent low-intensity, short duration exercise on mass, myofibrillar protein content and fiber size, the hindlimbs of adult female Wistar rats were suspended(HS) and half of these rats walked on a treadmill for 45 min/day(9 min every 2h) at 5m /min and a 15$^{\circ}$grade (HS-EX). Plantaris wet weight was 19.67% significantly smaller(p<0.005) and relative plantaris weight was 6.25% smaller compared with those of control rats following seven days of hindlimb suspension. Plantaris wet weight and relative plantaris weight increased by 27.66%, 12.22% each through intermit-tent exercise during hindlimb suspension(p<0.005, p<0.05), moreover, plantaris wet weight and relative plantaris weight of the HS-EX rats were similar to those of control rats. Soleus wet weight and relative soleus weight decreased significantly by 31% and 22.0% in the HS rats(p<0.05). Soleus wet weight and relative soleus weight increased by 10.41%, 25.64% respectively through intermittent ex-ercise during hindlimb suspension, furthermore, soleus wet weight and relative weight of the HS-EX rats were closer to those of control rats. Myofibrillar protein content of plantaris and soleus decreased significantly by 51.49%, 59.65% each, following seven days of hindlimb suspension (p<0.005) Myofibrillar protein content of plantaris and soleus increased by 51.79%, 75.47% each with significance through intermittent exercise during hindlimb suspension(p<0.005). Myofibrillar protein content of plantaris and soleus in HS-EX rats was smaller than that of control rats. No change was observed in fiber type percentage following 1 week of hindlimb suspension or exercise during hindlimb suspension. The type I fiber cross-sectional area of both soleus and plantaris muscle was 18.72% and 41.07% lower in the HS than that of the controls (p<0.05, p<.001), that of both muscles was 6.60% and 29. 3％ greater in the HS-EX than that of the HS rats. HS plus intermittent low- intensity short duration exercise resulted in Type I fiber cross-sectional area closer to the controls. Type II fiber cross-sectional area of both plantaris and soleus muscle was 22.45% and 22.58% sl nailer in the HS than in the controls, that of both muschles in the HS-EX was 14.10%, 5.78% greater than HS. Intermittent exercise during hindlimb suspension resulted in Type I, II fiber cross-sectional area closer to the control value. There was no change in SDH activity following 1week of hindlimb suspension or exercise during hindlimb suspension in the plantaris muscle. The results suggest that intermittent low intensity short duration exercise can ameliorate Type II muscular atrophy Induced by hindlimb suspension.

Complete denervation after severe brachial plexus injury make significant muscle atrophy with loss of proper function. It is much helpful to reconstruct the essential function of the elbow flexion movement in patient with total loss of elbow flexion motion after brachial plexus lesion which was not recovered with nerve surgery or long term conservative treatment from onset. In whole arm type brachial plexus injury, if there were no response to neurotization or neglected from injury, the volume of the denervated muscle is significantely reduced month by month. About 18 months most of the muscle fibers change to fibrous tissues and markedly atrophied irreversibly, further waiting is no more meaningful from that period. Authors performed 14 cases of functioning gracilis muscle transfer from 1981 to 1995 with microneurovascular technique, neuromusculocutaneous free flaps were performed for reconstruction of lost elbow flexion function. Average follow-up period was 5 years and 6 months. We used couple of intercostal nerves as a recipient nerve which were anastomosed to muscular nerve from obturator nerve in all cases. Recipient vessels were three deep brachial artery and eleven brachial artery which were anastomosed to medial femoral circumflex artery with end to end or end to side fashion. Average resting length of the transplanted gracilis were 24 cm. We can get average 54 degree flexion range of elbow with fair muscle power from flail elbow. There were one case of muscle necrosis with lately developed thrombosis of microvascular anastomosed site which comes from insufficient recipient arterial condition, 3 cases of partial marginal necrosis of distal skin of the transplanted part which were not significant problem with spontaneously solved with time goes by gracilis muscle has constant neurovascular pattern with relatively easy harvesting donor with minimal donor morbidity. Especially it has similar length and shape with biceps brachii muscle of upper arm and longer nerve pedicle which can neurorrhaphy with intercostal nerve without nerve graft if sufficient mobilization of the nerves from both sides of gracilis and intercostal region. Authors can propose gracilis muscle transplantation with intercostal nerves neurotization is helpful method with minimal donor morbidity for neglected brachial plexus palsy patients.

Purpose: There are many articles describing about Guyon canal compression syndrome. Until recently, most of these articles have been presented about the symptoms of ulnar nerve compression, but there have been no reports about ulnar artery compression. In this article, besides the nerve compression symptoms in the Guyon's canal, we represented the symptoms and treatments based on the ulnar artery obstruction. Methods: Guyon canal is composed of the hamate and pisiform, and the ligaments which connect them. The course of the ulnar nerve and artery, which passes through this narrow canal, is affected by the anatomical structure of the base of the canal. Out of 14 patients (21 cases) were retrospectively reviewed in this study from 2006 to 2009. Of 14 patients, there were 5 men and 9 women with ages between 21 to 61 years old. The symptoms had volar sensory loss of ulnar sided digits, with muscular atrophy of hypothenar muscles. Prior to surgery, most of these patients had vascular disorders which was diagnosed definitively by angiography and electromyogram. Results: The release of Guyon canal and interposition graft of the obstructed arteries was carried out to 11 patients (15 cases) who had artery (vascular) occlusive disorder, and. 12 cases had sympathectomy and interposition graft after resection of obstructed ulnar artery. Six cases had release of carpal tunnel performed simultaneously. There were no major complications after surgery. The circulation of the ulnar artery was improved along with the patients' symptoms. Conclusion: The pre-existing articles about Guyon canal compression syndrome were mainly focused on ulnar nerve compression. This study, which was carried out by our department, showed that most of these patients had ulnar artery obstruction or stenosis simultaneously with ulnar nerve compression. The vascular disorder was corrected by interposition graft after the resection of the site of ulnar artery occlusion. And to conclude, When we resolve the ulnar nerve compression, the proper diagnosis & treatment of impaired ulnar artery circulation should be carried out concomitantly.

Parkinson's disease is one of the typical neurodegenerative disease and it is caused by the destruction of substantia nigra in brain leading to lack of dopamine secretion, and it presents 4 major motor symptoms such as tremor, bradykinesia, stiffness, postural instability. Furthermore, it causes many non-motor symptoms such as anosmia, REM sleep conduct disorder, orthostatic hypotension, dementia and autonomic ataxia such as lack of adjusting blood pressure, hyperhydrosis, constipation. Dopaminergic therapy is the most commonly used strategy, but long term treatment of levodopa induce various adverse effects. Thus, many people are focusing on new therapies other than established therapies, and there are many tries and approaches with paradigm shift. Our medical team was able to get 4 cases of PD patients who are hospitalized in our hospital, treated by Whole Body Gi-Hyeol Therapy consisting of acupuncture therapy, herbal therapy, and mental therapy, and their conditions improved in perspective of Unified Parkinson's Disease Rating Scale(UPDRS), Heart Rate Variability(HRV), and Quality of life. Among all 4 cases, UPDRS score and quality of life score is gotton better, and among 2 cases SDNN, RMS-SD, TP, LF, HF scores are finely increased. And PDQ-39 score which shows quality of life is also improved. However, in spite of these improvements and positive results, there were no meaningful improvement in a hurt from a fall which is important to the aged, muscular atrophy which causes bone fracture and SMI(Skeletal Muscle Mass Index) which is indicator of osteoporosis. Thus, supplementary treatment about Whole Body Gi-Hyeol Therapy such as more active nutrition intervention, safe and effective kinesitherapy is needed, and from now on continuous case reports and systematic clinical research which has control group must be carried out.

Objective s: Chromosome aneuploidy is associated with recurrent abortion and congenital anomaly and genetic diseases occur repeatedly in the specific families. Preimplantation genetic diagnosis (PGD) can prevent aneuploidy or genetic disease by selecting normal embryos before implantation and is an alternative to prenatal diagnosis. The aim of this study is to assess the outcome of PGD cycles by using FISH or PCR, and to determine the clinical usefulness and values in patients with risk of chromosomal aneuploidy or genetic disease. Materials and Methods: From 1995 to Apr. 2001, a total of 108 PGD cycles in 65 patients with poor reproductive outcome were analyzed. The indications of PGD were translocation (n=49), inversion (n=2), aneuploidy screening (n=7), Duchenne muscular dystrophy (n=5) and spinal muscular atrophy (n=2). PGD was applied due to the history of recurrent abortion, previous birth of affected child or risk of aneuploidy related to sex chromosome aneuploidy or old age. Blastomere biopsy was performed in 6$\sim$10 cell stage embryo after IVF with ICSI. In the single blastomere, chromosome aneuploidy was diagnosed by using FISH and PCR was performed for the diagnosis of exon deletion in DMD or SMA. Results: The FISH or PCR amplification was successful in 94.3% of biopsied blastomeres. The rate of transferable balanced emb ryos was 24.0% in the chromosome translocation and inversion, 57.1% for the DMD and SMA, and 28.8% for the aneuploidy screening. Overall hCG positive rate per transfer was 17.8% (18/101) and clinical pregnancy rate was 13.9% (14/101) (11 term pregnancy, 3 abortion, and 4 biochemical pregnancy). The clinical pregnancy rate of translocation and inversion was 12.9% (11/85) and abortion rate was 27.3% (3/11). In the DMD and SMA, the clinical pregnancy rate was 33.3% (3/9) and all delivered at term. The PGD results were confirmed by amniocentesis and were correct. When the embryos developed to compaction or morula, the pregnancy rate was higher (32%) than that of the cases without compaction (7.2%, p<0.01). Conclusions: PGD by using FISH or PCR is useful to get n ormal pregnancy by reducing spontaneous abortion associated with chromosome aneuploidy in the patients with structural chromosome aberration or risk of aneuploidy and can prevent genetic disease prior to implantation.
