Medication Adherence in Patients Taking Immunosuppressants after Kidney Transplantation / 대한이식학회지

BACKGROUND: Kidney transplant recipients inevitably take a life-long immunosuppressive medication to prevent graft rejection. Non-compliance to immunosuppressive medication is one of the main causes leading to acute and chronic rejection and diminished renal function, resulting in a return to dialysis, increased morbidity, or mortality with an additional health care cost and poor quality of life. The purpose of this study was to investigate actual medication compliance and its related factors. METHODS: A total of 222 functioning kidney transplant recipients were surveyed in a single center, and 25 patients were excluded due to incomplete responses. We reviewed medical records retrospectively, and the data were statistically analyzed with SPSS version 13.0. RESULTS: Among 197 patients, 113 (57.4%) were compliant to the immunosuppressive agents, and 84 (42.6%) recipients were non-compliant. Non-compliant patients were significantly younger (P=0.004), highly educated (P=0.004), employed (P=0.005), more likely to live alone (P=0.035), and drank more (P=0.001) than the compliant patients. Regarding psychosocial factors, more barriers (P=0.015), weak beliefs about the necessity of taking medications (P=0.001), strong beliefs about specific concerns related to medications (P=0.038), and low self efficacy (P=0.003) were identified in the non-compliant group compared with the compliant group. CONCLUSIONS: This study revealed that multiple factors affected medication compliance in patients taking immunosuppressants. It would be helpful to identify potential recipients with a risk for non-compliance based on their general characteristics and psychosocial factors, so they can be provided a specialized education program to promote compliance. This strategy may help produce more favorable long-term outcomes among kidney transplant recipients.

The Nationwide Surveillance Results of Nosocomial Infections along with Antimicrobial Resistance in Intensive Care Units of Sixteen University Hospitals in Korea, 2004 / 병원감염관리

BACKGROUND: This study was to evaluate a nationwide nosocomial infection rate and antimicrobial resistance in intensive care units(ICUs) in Korea. METHODS: The study was carried out at 16 university-affiliated teaching hospitals from July through October 2004. We performed a prospective multicenter study to investigate nosocomial infection rates, device-associated infection rated, and causative pathogens and their antimicrobial resistance. RESULTS: The urinary tract was the most commonly involved site. Nosocomial infection rate was 12.48 in medical. ICU (MICU), 9.59 in medical surgical ICU (MSICU), 14.76 in surgical ICU (MSICU), and 11.60 in other lCU. Device-associated infection rates were as follow: 1) rates of urinary catheter-associated urinary tract infection were 4.26 in MICU, 3.17 in SICU, 4.88 in MSICU, and 5.87 in other ICU; 2) rates of central line-associated bloodstream infection were 3.24 in MICU, 1.56 in SlCU, 2.36 in MSICU, and 1.78 in other ICU; 3) rates of ventilator-associated pneumonia were 3.61 in MlCU, 13.05 in SICU, 1.68 in MSICU, and 4.84 in other lCU. Staphylococcus aureus was the most frequently identified microorganism in this study; 93% of S. aurues were resistant to methicillin; 17% of Pseudomonas aeruginosa isolated were resistant to imipenem; 11% of Enterococcus faecium and 18% of Enterococcus faecalis showed resistance to vancomycin. Over a half of Acinetobacter spp, Stenotrophomonas maltophilia, Klebsiella pneumoniae, and Escherichia coli showed resistant to fluoroquinolone. Conclusion: This study shows the seriousness of antimicrobial resistance and the importance of infection control in the lCU in Korea. This study should provide a theoretical strategy to enforce the infection control.

A case of intestinal non-rotation incidentally detected on DISIDA scan / 대한내과학회지

The most common developmental anomaly of midgut rotation and fixation is non-rotation. Symptomatic intestinal malrotation is relatively common in infants and children but uncommon in later ages. Most adult cases are silent throughout life and are not discovered unless they cause acute or chronic abdominal pain. Many such patients have ill-defined abdominal complaints and are labeled as having a "functional" disorder since no definite clinical abnormalities are found other than the subjective complaints. The most frequent symptomatic presentation in the adult is midgut volvulus the symptom of which is usually self-limited although often recurrent and sometimes leading to an abdominal catastrophe. The diagnostic means for the adulthood malrotation include simple and contrast radiographic studies and CT scan. Malrotation first detected by cholescintigraphy is rare. We report a case of intestinal non-rotation incidentally discovered on DISIDA hepatobiliary scintiscan.

Development and Clinical Application of Critical Pathway for Cleft Lip and Palate

Objectives of this study is to determine the effect of a critical pathway on hospital stays and outcomes after cleft lip and palate repair. During a period of eleven months from March 2000 to January 2001, twenty six cases to applied by critical pathway for cleft lip and palate were followed up. Comparisions were made between the precritical pathway and postcritical pathway groups. The results of this study showed that expenses of treatment for cleft lip and palate was reduced to 20%, 30% respectively, after critical pathway. After critical pathway, hospital stays for cleft lip and palate was reduced to from 7 days to 4 days, from 9 days to 6 days, respectively. Postoperative complications was not increased. Patient satisfactions was increased because of the detailed explanations and reduced hospital stays. Conclusively, significant decreases in length of hospital stay are seen, and cost reductions can be realized after critical pathway.

A Case of Hereditary Hemorrhagic Telangiectasia / 대한간학회지

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant inherited disease characterized by telangiectasias of the skin, mucous membranes, and various organ system. HHT is not unusual in western countries but there were several reported cases of HHT in Korea. Recently we evaluated a 40-year-old postpartum female who had been suffering from recurrent epistaxis and peripartum dyspnea. The patient was diagnosed as a HHT complicated by high output heart failure caused by intrahepatic arteriovenous malformation. This case is reported with a review of relevant literature.

Pleural fluid to serum cholinesterase ratio for the differential diagnosis of transudates and exsudates / 결핵

BACKGROUND: The criteria established by Light et al in 1972 have been used widely for the differential diagnosis of the pleural effusions in transudates and exsudates. However, in recent years, several reports have agreed that these criteria misclassified an important number of effusions. For this reason, different parameters have been proposed for differentiation the transudates from exudates. Nevertheless, all these alternative parameters have not been better than the past criteria of Light et al. In response the usefulness of two parameters for differentiation pleural transudate from exudates were evaluated : pleural fluid cholinesterase level and pleural fluid to serum cholinesterase ratio. METHODS: A total of forty-three patient with know causes of the pleura effusion by diagnostic thoracentesis were studied. The following criteria for differentiating the pleural effusions in transudates and exsudates were analyzed : Light's criteria, the pleural fluid cholesterol level, the pleural fluid to serum cholesterol ratio. the pleural fluid cholinesterase level, and the pleural fluid to serum cholinesterase ratio. RESULTS: The conditions of forty-three patients were diagnosed. Ten were classified as having transudates and thirty-three as exudates. The percentage of effusions misclassified by each parameter was as follows : Light's criteria, 9.3% ; pleural fluid cholesterol, 2.3% ; pleural fluid to serum cholesterol ratio, 2.3% ; pleural fluid cholinesterase, 4.7% ; and pleural fluid to serum cholinesterase ratio, 2.3%. CONCLUSIONS: The pleural fluid to serum cholinesterase ratio is one of the accurate criteria for differentiating pleural transudates from exudates. If further studies confirm these results, the cholinesterase ratio could be used as the first step in the evaluation of pleural effusion and if evaluated together with the other criteria, the differentiation of pleural transudate from exsudates will become more accurate.

A Case of the Massive Upper GI Bleeding from the Arteriovenous Malformation of Stomach / 대한소화기내시경학회지

The arteriovenous malformation(AVM) of the gastrointestinal tract is a rare cause of gastrointestinal bleeding. With the increasing use of angiography over the past 30 years in the assessment of gastrointestinal bleeding, AVM has been more frequently recognized. There are few reports, however, about the arteriovenous malformation of stomach. From 1884, about 40 cases were reported all over the world. The clinical manifestation of gastric AVM are asymptomatic massive upper gastrointestinal bleeding or chronic iron deficiency anemia, The diagnosis of gastric AVM is difficult because of nonspecific findings using an endoscopy. This lesion is easily detected using a selective angiography. Furthermore, the therapeutic embolization of the feeding artery have a better chance for stopping the bleeding. In this paper we are reporting one case of gastric AV malformation, wherein rnassive UGI bleeding and dingnosis was made usmg a selective angiography. A review of literatmes was conducted to make this report possible.

Significance of Serum Cortisol and Peripheral Blood Leukocyte Differential for the Early Differential Diagnosis of Acute Chest Pain Syndrome

OBJECTIVES: The stress response involves the activation of the hypothalamic-pituitary-adrenal(HPA) axis and the sympathetic nervous system. Corticosteroids have been clearly demonstrated to cause anti-inflammatory and/or immnosuppressive effects in man including granulocytosis in part by decreasing migration into tissue, especially damaged tissues(myocardium), and circulating relative lymphocytopenia. To test whether automated measurements of the the increased serum cortisol-induced hematologic changes in the leukocyte differential significance or not in the initial differential diagnosis of acute myocardial infarction in acute chest pain syndromes. METHODS: 101 consecutive patients with myocardial infarction or myocardial ischemia presenting to the emergency room of Seoul Adventist Hospital with acute chest pain from January 1993 to August 1995(Retrospective group) and from December 1995 to March patients compatible with exclusion criteria in myocardial infarction were excluded. We measured automated leukocyte differential and serial CK-MB level in both groups, and the intial serum cortisol levels in prospective infarction group. RESULTS: 1) Total leukocyte and granulocyte counts were increased in acute myocardial infarction(p<0.01). 2) In acute myocardial infarction group, lymphocyte counts were slightly increased(p<0.05), but relative lymphocytes percentage more significantly decreased(p<0.01). 3) Serum cortisol levels are significantly raised early in the course of the acute myocardial infarction and prior to the elevation of the specific cardiac enzymes on the basis of analytic results of prospective infarction group. 4) Cortisol-induced changes in leukocyte differential were noted with time passes into reverse approximately 4 days later in our study. 5) The leukocyte differential does not shows significant changes in the retrospective myocardial ischemia group, so we arrive in careful conclusion that serum cortisol level seems does not increase. 6) No sexual differences were noted in leukocyte differential. CONCLUSIONS: The serum cortisol level and cortisol-induced leukocyte differential are helpful for initial differential diagnosis of acute myocardial infarction in acute chest pain sysdrome.

A Case of Percutaneous Aspiration Thromboembolectomy(PAT)

The two most common causes of acute arterial occlusion are embolism and thrombosis in sity. They are mainly originated from the cardiovascular sources. About 70-80 per cent of occlusions occur in the axial limb vessels. Therapeutic options include supportive measures, pharmacologic treatment, surgery, and non-operative interventions. There have been several successful case reports using percutaneous aspiration thromboembolectomy with the advent of new instruments and technical imprevement. We report a case of 70-year-old male with acute anterior wall myocardial infaction who experienced acute embolic arterial occlusion of the left popliteal artery from mural thrombus in the left ventricular apex. It wan managed successfully by percutaneous aspiration thromboembolectomy.
