The authors have studied 37 Korean embryos of Carnegie stage 11~23 and 18 fetuses to demonstrate the development of the shoulder joint. The external feature of the upperlimb bud is observed by stereoscope and camera, and the internal structures are studied by microscopic observation. The results obtained were as follows: In stage 12 upperlimb buds were appeared. In stage 17 mesenchymal condensations for humerus and scapula, and glenoid labrum were observed. In stage 19 one-layered interzone between the humerus and scapula was visible. In stage 22 three-layered interzone between the humerus and glenoid labrum was formed. In stage 23 three-layered interzone between the humerus and glenoid fossa of scapula was visible. In the 9th and 10th weeks distinct joint cavity was formed between humerus and glenoid labrum, and tendon of long head of Biceps brachii was attached to supraglenoid tuberosity and glenoid labrum. In the 11th week the joint cavity was formed between the midportion of humerus and glenoid fossa, and tendon of long head of Biceps brachii was more dense. In the 16th week the glenoid labrum was visible as fibrous cartilage, and joint cavity was more widened. In the 20th to 32nd week the shoulder joint was matured with the distinct joint cavity and glenoid labrum time after time.

Deveolopmental coax vara represents coax vara not present at birth but rather developing in early childhood, showing a progressive deterioration in the proximal femoral neck-shaft angle during growth. In order to determine the factors that could affect the results of corrective osteotomy, we evaluated the results of 15 developmental coax vara in 12 patients who had been treated with the femoral osteotomy at the Department of Pediatric Orthopedic Surgery, Seoul National University Children's Hospital, from February 1983 to March 1993. Of the 12 patients, there were 6 boys and 6 girls. Three patients had bilateral operations, 5 patients on the right, and the remaining 4 patients on the left. Average at the onset of symptoms was 4 years plus 5 months(range; from 1 year to 7 years plus 2 months), and average age at the tome of operation was 6 years plus 3 months(range; from 2 years plus 4 months to 10 years). We could obtain the following results: 1. Average post-operative loss of neck-shaft angle was 5% in the cases in which post-operative neck-shaft angle was converted more than 130 degrees, and was 8% in the cases in which post-operative neck-shaft angle was converted less than 130 degrees. 2. Loss of neck-shaft angle was higher during the first post-operative period, and was higher in cases in which the triangular osseous defect was persistent post-operatively. There was no correlation between the post-operative neck-shaft angle and disappearance of triangular osseous defect. 3. The femoral anteversion was converted 8.7 degrees to 27.2 postoperatively. 4. The premature arrest of the capital femoral physis was higher in cases in which the neck-shaft angle was less than 130 degrees postoperatively. 5. Leg length discrepancy, which was 2.1 cm preoperatively, did not change in cases in which the neck-shaft angle was more than 130 degrees postoperatively. However, it was converted to 3.3 cm in cases in which the neck-shaft angle was less than 130 postoperatively. 6. we could observe the femoral head deformity in 6 out of 7 cases in which the operation was performed after 7 years of age. We could draw the following conclusion based on our results: 1. We must correct the neck-shaft angle more than 130 degrees. 2. We could not equalize the leg length discrepancy by corrective osteotomy alone. 3. It may be reasonable to perform the corrective osteotomy before 7 years of age.

Esophageal hematoma is a rare form of esophageal injury. It may occur spontaneously, or in association with direct esophageal damage or a bleeding diathesis. Endoscopy and computed tomography are generally necessary for the establishment of a diagnosis. In this report, we present a case of esophageal hematoma that was discovered via a bedside transthoracic echocardiography. The echocardiography was conducted to evaluate an unexplained shock in a critically ill-patient. After conservative treatment, complete resolution of the esophageal hematoma was documented by a 7-day short-term follow-up of bedside transthoracic echocardiography. To the best of our knowledge, this is the first case report regarding transthoracic echocardiographic detection, differential diagnosis, and follow-up for esophageal hematoma.

Hemolytic anemia is recognized as a rare complication of mitral valve replacement or repair. We report on a 44-year-old man with shortness of breath and hemolytic anemia, 23 years after mitral valve replacement (Hall-Kaster), and a 63-year-old woman diagnosed of hemolytic anemia, 4 years after mitral and tricuspid annuloplasty (Tailor ring, An-core ring). Routine 2-dimensional transthoracic echocardiography revealed paravalvular leakage around the prosthesis. Subsequent real-time 3-dimensional (3D)transesophageal echocardiography helped the perceptional appreciation of the leakage and the measuring of the regurgitant orifice area using the anatomically correct plane. Surgical findings of each case fit those of 3D volumetric images.

BACKGROUND: Perioperative transfusion of red blood cell (RBC) may cause adverse effects. Bloodless-cardiac surgery has been spotlighted to avoid those problems. Off pump coronary artery bypass (OPCAB) surgery can decrease the transfusion. However, the risk factors of transfusions in OPCAB have not been investigated properly. MATERIALS AND METHODS: One hundred and thirteen patients (male:female=35:78, mean age=66.7+/-9.9 years) who received isolated OPCAB were retrospectively analyzed from March 2006 to September 2007. The threshold of RBC transfusion was 28.0% of hematocrit. Bilateral internal thoracic arteries graft were used for 99 patients (87.6%). One hundred and three (91.1%) and 35 patients (31.5%) took aspirin and clopidogrel just before surgery. RESULTS: Sixty-five patients (47.5%) received the RBC transfusion (mean 2.2+/-3.2 units). Mortality and major complications were not different between transfusion and no-transfusion group. But, ventilator support time, intensive care unit stay and hospitalization period had been reduced in no-transfusion group (p<0.05). In multivariate analysis, patients risk factors for RBC transfusion were preoperative low hematocrit (<37.5%) and clopidogrel medication. Surgical risk factors were longer graft harvesting time (>75 minutes) and total operation time (>5.5 hours, p<0.05). CONCLUSION: We performed the transfusion according to transfusion guideline; over 40% cases could conduct the OPCAB without transfusion. There were no differences in major clinical results between transfusion and non-transfusion group. In addition, when used together with accurate understanding of transfusion risk factors, it is expected to increase the proportion of patients that do not undergo transfusions.

Dieulafoy's disease, a vascular anomaly mainly in the upper stomach, is a rare but potentially life-threatening cause of upper gastrointestinal bleeding. Pathogenesis is still controversial, but the most accepted theory is that a persistent caliber vessel in the submucosa is exposed by a small mucosal erosion leading to massive bleeding. The bleeding site is usually within 6 cm of the esophagogastric junction in the cardia or fundus of the stomach. The treatment of choice is therapeutic endoscopy or surgery. The age of patients reported is mainly between 50 and 70 years, and patients of pediatric age are extremely rare. We are reporting a 5-year-old male patient who had Dieulafoy's disease which was diagnosed by emergency upper gastrointestinal endoscopy. Endoscopic finding was a nodular lesion with an adherent clot on the lessor curvature of the stomach 2 cm below the esophagogastric junction. Epinephrine and Beriplast(R) was injected in the lesion. On the second day after endoscopic sclerotherapy, the patient had recurred massive hematemesis and accompanying shock. So we performed gastrotomy and ligation. After the operation, he showed an improved general condition and was discharged at the 12th hospital day.

OBJECTIVE: To determine the effects of cervical kyphosis on the recovery of swallowing function in subacute stroke patients. METHODS: Baseline and 1-month follow-up videofluoroscopic swallowing studies (VFSSs) of 51 stroke patients were retrospectively analyzed. The patients were divided into the cervical kyphosis (Cobb's angle <20°, n=27) and control (n=24) groups. The penetration-aspiration scale (PAS), American Speech-Language-Hearing Association National Outcomes Measurement System swallowing scale (ASHA NOMS), and videofluoroscopic dysphagia scale (VDS) were used to determine the severity of dysphagia. Finally, the prevalence of abnormal VFSS findings was compared between the two groups. RESULTS: There were no significant differences in baseline PAS, ASHA NOMS, and VDS scores between the two groups. However, the follow-up VDS scores in the cervical kyphosis group were significantly higher than those in the control group (p=0.04), and a follow-up study showed a tendency towards worse ASHA NOMS scores (p=0.07) in the cervical kyphosis group. In addition, the cervical kyphosis group had a higher occurrence of pharyngeal wall coating in both baseline and follow-up studies, as well as increased aspiration in follow-up studies (p<0.05). CONCLUSION: This study showed that stroke patients who had cervical kyphosis at the time of stroke might have impaired recovery from dysphagia after stroke.
