뇌졸중 환자의 호흡근 훈련자세가 호흡근 활성도에 미치는 영향

정주현,김난수 대한스포츠물리치료학회 2018 정형스포츠물리치료학회지 Vol.14 No.1

Purpose: This study investigated the effects of respiratory muscle training posture on respiratory muscle activation in stroke patients and presented appropriate posture for the respiratory muscle training. Methods: Thirty-six stroke patients were assigned to either a neutral training posture (n = 13), habitual training posture (n = 12), or side bending training posture (n = 11) group. Respiratory muscle training was conducted using an inspiratory muscle trainer. Each group was asked to adopt either a neutral, habitual, or side-bending posture during respiratory muscle training, which was performed for 30 minutes per day, 10 sets, 3 times per week, for a total of 6 weeks. After each session, external intercostal muscles and sternocleidomastoid muscle activity were measured via surface electromyography. Results: The paretic or non-paretic side intercostal muscle differed significantly in the three groups, and the non-paretic side intercostal muscle was significantly decreased in the neutral training group. The non-paretic side sternocleidomastoid muscle differed significantly in the three groups, and the nonparetic side sternocleidomastoid muscle was significantly increased in the habitual training group. Conclusion: A neutral posture, where appropriate spine and trunk alignment is maintained, is a more effective posture for respiratory muscle training for improving respiratory function in stroke patients.

Ileocecocolic and Colocolic Intussusception in a Young Jindo

정주현,채웅주,권도형,장진화,오선경,윤정희,최민철 한국임상수의학회 2008 한국임상수의학회지 Vol.25 No.6

An eight-month-old, intact female Jindo, weighing 9 kg with a one-day history of acute bloody diarrhea was referred. Plain abdominal radiographic findings included evidence of a soft tissue tubular mass within the dilated colon. In ultrasonographs, a target-like mass was identified with multiple hyperechoic and hypoechoic parallel wall layers. A barium enema showed a large radiolucent filling defect within the colon and a completely occlusive lumen. On the basis of these images, ileocecocolic and colocolic intussusception was diagnosed. Surgical manual reduction, resection and anastomosis were performed. The patient recovered normally without any complications or recurrence.

개에서 문맥홀정맥단락의 진단 영상 및 치료 1 례

정주현,권도형,윤정희,최민철,장진화 한국임상수의학회 2009 한국임상수의학회지 Vol.26 No.1

An intact female, 5-year old, Shihtzu, weighing 3.2 kg with a history of depression, hypersalivation, dullness, and ataxia for 3 days was referred. Radiographic findings included microhepatica, bilateral renal calculi, and a cystic calculus. Ultrasonography showed microhepatica, decreased visibility of portal veins in the liver, bilateral renal calculi, a cystic calculus, and an abnormal tortuous dilated vessel in the craniodorsal abdomen. A single congenital extrahepatic portoazygous shunt was confirmed through operative mesenteric portography. The patient received surgery using an ameroid constrictor ring and recovered well.

맹장에 발생한 단일성 결절형 소화관 림프종의 영상 진단 증례

정주현,권도형,이승희,오선경,윤정희,최민철,장진화 한국임상수의학회 2009 한국임상수의학회지 Vol.26 No.1

A spayed female, 8-year-old, maltese, weighing 1.84 kg with a history of acute severe vomiting, anorexia, depression for 2 day was referred. An abdominal mass was palpated with abdominal pain on physical examination. Radiographic findings included two soft tissue density masses in the mid-abdominal cavity and gas dilated colon. Ultrasonographs showed one heterogeneous hypoechoic round mass including intestinal wall. There were loss of normal wall layering and motility and absence of internal lumen of the intestinal wall. And another heterogeneous hyperechoic mass was identified to the medial side of the intestinal mass. Based on clinical signs, image findings, and the result of fine needle aspiration, intestinal obstruction due to alimentary lymphoma was diagnosed. On surgery, a cecal lymphoma and mesenteric lymphadenopathy were confirmed and the cecal mass was resected.

골피판술과 비내시경적 접근을 이용한 상악동 양성 종물의 치료

정주현,김선태,차흥억,강일규 대한비과학회 2010 Journal of rhinology Vol.17 No.2

Objective:This article describes use of the osteoplastic technique in the treatment of maxillary benign tumors. This procedure yielded favorable outcomes in situations where the tumor was difficult to remove using the standard endoscopic approach. Methods:This study included six sinuses of six patients with maxillary sinus benign tumors (five inverted papillomas and one hemangioma). The tumors were located in the anterior wall of the maxillary sinus and were difficult to remove by the endoscopic approach. The traditional gingivobuccal incision was performed to expose the anterior maxillary sinus wall. A rectangular bone flap was designed on the anterior maxillary wall and a bony window was made using a reciprocating saw. After eradicating all lesions, the bone flap was repositioned to its original site and fixed with a miniplate. Postoperative paranasal sinus computed tomography was performed after 12 and 24 months. Results:All bone flaps healed without any complications. Patients had succes-sful postoperative outcomes without any complications. In one inverted papilloma case, the lesion recurred and was removed easily with the same procedure. Conclusion:The osteoplastic technique is a simple and useful method to eradicate benign lesions in the maxillary sinus due to its good access to the maxillary sinus antrum, optical surgical view, and minimal complications.

Colonic Leiomyoma in Two Dogs

정주현,채웅주,권도형,최민철 한국임상수의학회 2014 한국임상수의학회지 Vol.31 No.5

Two dogs were referred with the clinical signs of depression and constipation, respectively. One dog withdepression had hypoglycemia on biochemistry. On survey abdominal radiographs, a soft tissue density round masswith calcified spots was identified cranial to the urinary bladder. On ultrasonographs, a solitary oval heterogeneouscomplex-echoic mass with well-defined margin was found. On surgery, the mass was pedunculated and originated fromthe colonic wall. The resected mass was confirmed as colonic leiomyoma. The other dog with constipation had normalCBC and biochemistry values. On survey abdominal radiographs, there was a soft tissue density round mass dorsalto the descending colon and rectum. The descending colon was displaced ventrally and narrowed by the mass. Onultrasonographs, a well-defined round heteroechoic mass compressed the colon. The mass was also pedunculated andoriginated from the colonic wall on surgery and confirmed as colonic leiomyoma. Two dogs recovered without anyclinical signs after surgery and showed permanent resolution of the clinical signs, respectively.

Renal Amyloidosis in a Beagle

정주현,진재봉,이현욱,최민철 한국임상수의학회 2014 한국임상수의학회지 Vol.31 No.6

An eight-year-old intact male Beagle had anorexia, vomiting, depression for two days. The dog hadhypoalbuminenia and mild azotemia on hematologic and clinical chemistry examinations. Severe proteinuria wasidentified on urinalysis. On abdominal ultrasonographs, there were small amount of ascites and bilateral renomegalywith severe hyperechoic renal cortex and hyperechoic medullary rim sign. Renal biopsy and histopathology revealedrenal amyloidosis. The quality of life in this dog was satisfactory with aggressive supportive care for three months. Euthanasia was performed due to deteriorated azotemia and nephrotic syndrome.
