Heart Septal Defects, Ventricular*

Evlauation of pulmonary vascular changes and pre-and postoperative hemodynamic findings were performed in 25 patients who had ventricular septal defect associated with sevese pulmonary hypertension. Lung biopsy were done preoperatively in two patients and during operation in twenty three patients. Also the postoperative systemic and polmonary arterial pressure were obtained about 10-20 minutes after the cardiopulmonary bypass. The results were as follow: 1) There was no relationship between the severity of pulmonary vascular changes(Health-Edwards classification) and the patients age(X2=4.4427, P=0.2175). 2) There was a good correlation between preoperative ratio of pulmonary to systemic vascular resistance(Rp/Rs) and ratio of pre-and postoperative pulmonary to systemic arterial pressure(r=0.4846, P<0.05). 3) There was a significant correlation between the degree of medial wall thickness and preoperative Rp/Rs(r=0.6535, P<0.005). 4) There was no correlation between perioperative hemodynamic findings and medial wall thickness in the patients aged below 2 years.

PURPOSE: The purpose of this study is to analyze the structural model on the Nursing Task Performance of Hospital Nurses. METHODS: Data collection was done by the 200 hospital nurses from May 1st to May 20th, 2013 in Seoul city. The sample variance-covariance matrix was analyzed using AMOS 19.0 and the maximum likelihood minimization function. The goodness of fit was evaluated using the SRMR, RMSEA and its 90% confidence interval, CFI, and TLI. RESULTS: First, hospital nurses' organizational justice and empowerment was not found to have a significant direct effect on nursing task performance. Second, organizational justice and empowerment had a direct effect on job satisfaction and organizational commitment. Third, organizational commitment was found to have a significant direct effect on nursing task performance. Forth, hospital nurses' empowerment was found to have a significant direct effect on nursing task performance. CONCLUSION: Nurses' nursing task performance was influenced by organizational justice, empowerment, and organizational commitment. In order to increase the degree of nursing task performance in hospital nurse, it is necessary to develop the nursing program and its application considering hospital nurses' organizational justice and empowerment and organizational commitment.

BACKGROUND: Pancreatic pseudocysts are localized collections of pancreatic secretions in a cystic structure that lack an epithelial lining and occur as a result of surrounding tissues walling off and containing a pancreatic duct disruption. METHODS: This is paper presents a clinical analysis of 32 cases of pancreatic pseudocysts treated from January 1987 to July 1997 at Pusan Medical Center. RESULTS: The results are summarized briefly as follows: 1) The age and the sex distributions of these patients showed that 19 cases occurred between the 3rd and the 4th decades and the male-to-female ratio was 10.3:1. 2) Pancreatitis was most frequently associated with pancreatic pseudocysts (75%). 3) Common clinical manifestations were abdominal pain (89%), abdominal tenderness (78%), nausea and vomiting (56%), abdominal mass (32%), abdominal distension (31%). 4) Abdominal CT and ultrasound were major diagnostic methods. 5) The location of the peudocysts were the body (41%), head and tail (31%), the tail (22%), and others (6%). 6) The sizes of the pseudocysts were as follows less than 5 cm (5 cases), 5-10 cm (19 cases), above 11 cm (8 cases) in 32 cases. 7) Valuable laboratory data for a pancreatic pseudocyst were blood WBC count (above 10,000/mm in 78%), serum amylase (above 160 unit/L in 62%), urine amylase (above 300 unit/L in 56%), blood glucose (above 110 mg/L in 50%), serum alkaline phosphatase (above 250/L in 44%). 8) The surgical methods in 29 cases were excision (1 case), external drainage (4 cases), cystogastrostomy (7 cases), cystojejunostomy (16 cases), cystoduodenostomy (1 case). 9) Postoperative complications were encountered in 13 cases, and many of the cases involved pulmonary complications and wound infections. CONCLUSIONS: Currently, treatment of patients with pancreatic pseudocysts is based on the clinical setting, the presence or absence of symptoms, the age and size of the pseudocyst, and the presence or absence of complications. In the most common clinical settings, a pseudocyst is discovered after an episode of acute alcoholic pancreatitis.

Despite recent advances in nutritional support, patient monitoring, and surgical intensive care, as well as some improvement in surgical techniques, post-operative fistulas have been regarded as one of the most serious complications in abdominal surgery. The present study was undertaken to evaluate the effectiveness of treatment with total parenteral nutrition (TPN) alone (group A, n=26) or with TPN combined with octreotide, a long-acting analog of somatostatin (group B, n=20) in post-operative enterocutaneous fistulas. In group A, we treated 2 biliary, 10 pancreatic and 14 intestinal cutaneous fistulas with total parenteral nutrition. In group B, we treated 6 biliary, 8 pancreatic and 6 intestinal cutaneous fistulas with octreotide. The results obtained from the analysis are as follows: 1) The spontaneous closure of the fistulas was 69.2% in group A and 75.0% in group B. 2) The mean interval of time to achieve the healing of the fistula was 30.44 days in group A and 14.53 days in group B. 3) The mean interval of time to achieve a fistula output reduction of 50% was 6.44 days in group A and 2.44 days in group B. 4) In patients with low-output fistulas, the spontaneous closure of the fistula was 81.8% in group A and 80.0% in group B. In patients with high-output fistulas, the spontaneous closure of the fistula was 60.0% in group A and 73.3% in group B. 5) In patients with low albumin (< 3.0 g/dl), the spontaneous closure of the fistula was 54.5% in group A and 50.0% in group B. In patients with high albumin (> or = 3.0 g/dl), the spontaneous closure of the fistula was 80.0% in group A and 85.7% in group B. 6) In patients with an abdominal abscess, the spontaneous closure of the fistula was 40.0% in group A and 40.0% in group B. In patients without an abdominal abscess, the spontaneous closure of the fistula was 87.5% in group A and 86.7% in group B. 7) As compared with TPN, the spontaneous closure of the fistulas treated with octreotide was increased in the gastroduodenum and the external biliary system, was similar in the small bowel and the pancreas, but was decreased in the colon. We conclude that octreotide is a useful therapeutic complement in the conservative treatment of selected patients with post-operative cutaneous fistulas, especially fistulas in the external biliary system and the gastroduodenum.

Platelet-derived growth factor(PDGF) is known to accelerate soft tissue fracture and periodontal bone healing, but little information is available for characterizing the healing of articualr cartilage. This study was designed to demonstrate the regeneration potential of pasteurized autogeneous osteochondral graft when PDFG was applied locally in vivo. Eighteen rabbits in two groups were used in the experiment. The free osteochondral fragment(1x1x1 cm) were taken from distal femur. The fragment were pasteurized in 65degrees C for 5 minutes. In experimental group(group II), the fragment were soaked in 0.25 mg/ml of recombinant human PDGF mixed 5 ml normal saline and reimplanted to the resected site, and followed with local administration of 0.25 mg/ml PDGF to knee joint. In control group(group I), the pasteurized fragment were reimplanted in the resected site without any treatments. The histologic characteristics of the transplanted autografts for three rabbits in each group were observed at 3, 5 and 7 weeks postoperatively. The results were as follows; Group II revealed the more favorable regeneration of articular cartilage, less arthritic changes and more mature arrangement of chondrocytes than group I. Even thought the cartilage is avascular and the regeneration capacity of pasteurized cartilage is severely limited, the regeneration of grafted articular cartilage is thought to be accellerated by increased newly formed blood vessels and soft tissues due to the diffusion of PDGF on grafted cartilage, and probably also by differentiation of mesenchymal cells in the initial stage of experiment. The results of this study suggest that local administration of PDGF could be used for the treatment of posttraumatic or degenerative arthritis and various cartilage damages.
