Additive harmful effects of acute kidney injury and acute heart failure on mortality in hospitalized patients

Organ crosstalk between the kidney and the heart has been suggested. Acute kidney injury (AKI) and acute heart failure (AHF) are well-known independent risk factors for mortality in hospitalized patients. This study aimed to investigate if these conditions have an additive effect on mortality in hospitalized patients, as this has not been explored in previous studies. Methods: We retrospectively reviewed the records of 101,804 hospitalized patients who visited two tertiary hospitals in the Republic of Korea over a period of 5 years. AKI was diagnosed using serum creatinine-based criteria, and AHF was classified using International Classification of Diseases codes within 2 weeks after admission. Patients were divided into four groups according to the two conditions. The primary outcome was all-cause mortality. Results: AKI occurred in 6.8% of all patients (n = 6,920) and AHF in 1.2% (n = 1,244). Three hundred thirty-one patients (0.3%) developed both conditions while AKI alone was present in 6,589 patients (6.5%) and AHF alone in 913 patients (0.9%). Among the 5,181 patients (5.1%) who died, 20.8% died within 1 month. The hazard ratio for 1-month mortality was 29.23 in patients with both conditions, 15.00 for AKI only, and 3.39 for AHF only. The relative excess risk of interaction was 11.85 (95% confidence interval, 2.43–21.27), and was more prominent in patients aged <75 years and those without chronic heart failure. Conclusion: AKI and AHF have a detrimental additive effect on short-term mortality in hospitalized patients.

The Effect of K-MBSR Program on Stress, Stress Coping Style, Depression, Anger and Sleep of Middle Aged Women

PURPOSE: The purpose of this study was to examine a Korean Mindfulness Based Stress Reduction (K-MBSR) program for middle aged women and to verify the program's effectiveness on stress, stress coping style, depression, anger and sleep. METHODS: Fifty-two women aged from 40 to 59 (26 in the experimental group and 26 in the control group) from G city participated in the study. Data were collected from February 13 to April 3, 2013. The experimental group received 8 sessions, scheduled once a week, with each session lasting two and a half hours. Outcome variables included stress, stress coping style, depression, anger, sleep and a physiological measure (EEG). RESULTS: There were significant decreases for stress (t= - 2.14, p=.037), depression (t= - 2.64, p=.011), state trait anger (t= - 3.79, p<.001) in the experimental group compared to the control group. CONCLUSION: The findings in this study indicate that the K-MBSR program is an effective program to decrease stress, depression, and state trait anger in middle aged women.

Midazolam protects B35 neuroblastoma cells through Akt-phosphorylation in reactive oxygen species derived cellular injury / 대한마취과학회지

BACKGROUND: Soman, a potent irreversible acetylcholinesterase (AChE) inhibitor, induces delayed neuronal injury by reactive oxygen species (ROS). Midazolam is used in patients with pathologic effects of oxidative stresses such as infection, hemodynamic instability and hypoxia. We investigated whether midazolam protects the Central Nervous System (CNS) from soman intoxication. The present study was performed to determine whether midazolam protects B35 cells from ROS stress for the purpose of exploring an application of midazolam to soman intoxication. METHODS: Glucose oxidase (GOX) induced ROS stress was used in a B35 neuroblastoma cell model of ROS induced neuronal injury. To investigate the effect of midazolam on cell viability, LDH assays and fluorescence activated cell sorting (FACS) analysis was performed. Western blotting was used for evaluating whether Akt-phosphorylation is involved in cell-protective effects of midazolam. RESULTS: GOX derived ROS injury decreased cell viability about 1.6-2 times compared to control; midazolam treatment (5 and 10 microg/ml) dose-dependently increased cell viability during ROS injury. On western blots, Akt-phosphorylation was induced during pretreatment with midazolam; it was diminished during co-treatment with LY-294002, an inhibitor of Akt-phosphorylation. FACS analysis confirmed that the cell protective effect of midazolam is mediated by an anti-apoptotic effect. GOX-induced apoptosis was inhibited by midazolam and the finding was diminished by LY-294002. CONCLUSIONS: Midazolam protects neuronal cells from GOX-induced ROS injury; this effect is mediated by an anti-apoptotic effect through Akt-phosphorylation. This shows that midazolam may be useful in soman intoxication.

Prognostic Value of Body Mass Index in Korean Patients with Castration-Resistant Prostate Cancer

PURPOSE: We investigated the correlation between body mass index (BMI) and the prognosis of castration-resistant prostate cancer (CRPC) in patients who received docetaxel treatment. MATERIALS AND METHODS: A retrospective study was conducted of 55 patients who were diagnosed with CRPC and received docetaxel treatment between 2003 and 2009 at our institution. Patients with a normal or lower BMI ( or =23.0 kg/m2) were categorized as group II. Clinicopathological features and survival rates were evaluated by using the Kaplan-Meier method and Cox proportional hazards models. RESULTS: On the basis of BMI, 27 patients (49.1%) belonged to group I and 28 (50.9%) patients belonged to group II. Mean follow-up periods were 30 months and 34.2 months, respectively (p=0.381). There were no significant differences between the two groups in terms of age, prostate-specific antigen (PSA), Gleason score, Eastern Cooperative Oncology Group Performance Status, hemoglobin level, alkaline phosphatase level, distant metastasis, radiation treatments, or performance of radical prostatectomy (p>0.05). In the univariate analysis for predicting survival rates, BMI (p=0.005; hazard ratio [HR], 0.121), logPSA (p=0.044; HR, 2.878), and alkaline phosphatase level (p=0.039; HR, 8.582) were significant factors for prediction. In the multivariate analysis, BMI (p=0.005; HR, 0.55), logPSA (p=0.008; HR, 7.836), Gleason score (p=0.018; HR, 6.434), hemoglobin (p=0.006; HR, 0.096), alkaline phosphatase level (p=0.005; HR, 114.1), and metastasis to the internal organs (p=0.028; HR, 5.195) were significant factors for prediction. CONCLUSIONS: Better effects on the cancer-specific survival rate were observed in cases with higher BMI.

CONCLUSIONS: Better effects on the cancer-specific survival rate were observed in cases with higher BMI.

Establishing a Table of Glycemic Index Values for Common Korean Foods and an Evaluation of the Dietary Glycemic Index among the Korean Adult Population

Recent studies have reported that the glycemic index (GI) has an effect on developing the risk for metabolic abnormalities such as diabetes, dyslipidemia, and obesity. As there are no reliable GI values for common Korean foods, only a few studies have been carried out using the dietary GI for Korean adults. The aim of this study was to establish a table of GI values for common Korean foods and evaluate dietary glycemic index (DGI) and dietary glycemic load (DGL) among the Korean adult population. International tables of GI values and other published values were used to tabulate GI values for common Korean foods. Among 653 food items, 149 (22.8%) were adapted from published data, 60 (9.2%) were imputed from similar foods, and 444 (68.0%) were assigned a zero. Data from 7,940 subjects aged 20 years and older in the 2007-2008 Korea National Health and Nutrition Examination Survey were obtained, and DGI and DGL were calculated. The average DGI was 60.0 and the average DGL was 182.5 when the reference food GI value was glucose. After adjusting for potential confounding variables, DGI and DGL increased significantly according to age group (p for trend < 0.001). The food group that contributed most to DGL was grain and its products supplying 85.3% of total DGL, whereas the mean GI value in grain and its products was 72.6. Fruits and potatoes also contributed to DGL (5.8 and 2.9%, respectively), and their GIs were high (67.7 for potatoes and 45.8 for fruits). For individual food items, white rice supplied 66.7% of total GI followed by glutinous rice (2.3%) and steamed white rice cakes (2.0%). In conclusion, a table of GI values for 653 common food items was established in which white rice was the most contributing item to DGL. Our results will be useful to examine the relationships between DGI, DGL, and metabolic abnormalities in the Korean population.

The Correlations of the Radiological Parameters of Hip Dysplasia and Proximal Femoral Deformity in Clinically Normal Hips of a Korean Population

BACKGROUND: The aim of this study was to answer the following two questions: 1) Do the radiological parameters of dysplasia have significant correlations between themselves or with the parameters of the proximal femoral deformity and vice versa? 2) Do the physical parameters have a significant correlation with the radiological parameters of hip dysplasia and proximal femoral deformity? METHODS: Four hundred and twenty eight consecutive patients with no clinical evidence of hip osteoarthritis and who underwent pelvic radiography in the supine position for hip contusion or a routine health check were analyzed for the relationships between the center-edge (CE) angle, acetabular depth, acetabular angle, the head-neck ratio and the neck-shaft angle as well as the relationships of the above-mentioned variables with age, gender, body height and the body mass index. RESULTS: The CE angle, acetabular depth and acetabular angle showed a strong correlation with each other. The neck-shaft angle and the head-neck ratio showed no correlation with each other or with the CE angle, acetabular depth and acetabular angle. Age was positively associated with the CE angle, and inversely associated with the acetabular depth or acetabular angle. Male gender was significantly associated with the increased neck-shaft angle, and inversely associated with the head-neck ratio. CONCLUSIONS: The radiological parameters of hip dysplasia are all strongly, if not perfectly, inter-correlated. Age was associated with the radiological parameters of hip dysplasia whereas gender was associated with the radiological parameters of a proximal femoral deformity.

A Case of Fatal Pulmonary Embolism after Arthroscopic Partial Meniscectomy

Pulmonary embolism is a serious and fatal complication in orthopedic surgery. Most cases of pulmonary embolism in knee surgery have been reported after knee arthroplasty, but this is rare after arthroscopy. We describe here a case of fatal pulmonary embolism after arthroscopic partial meniscectomy in a female patient who was without any remarkable risk factors.

The Surgical Management of the Rheumatoid Wrist / 대한류마티스학회지

The wrist joint is often involved in the early stages of the rheumatoid arthritis (RA) and is regarded as a main target of the disease. Since the wrist plays a key role in the articulations of the upper extremities, appropriate treatment of this joint will preserve the patient's work ability and independence. When surgical intervention is considered, determining the disease extent is as important as the type of rheumatoid involvement. This can be achieved by performing an extensive clinical and functional assessment of the extremities. In addition, understanding radiological findings also helps to determine the type of rheumatoid destruction, and the subsequent treatment algorithms. Success of surgical management depends on a well-considered strategy in the timing of different procedures. Prophylactic surgery, such as a synovectomy of the joint or tendon could be performed in the early stages to prevent further destruction and deformation. As destruction at the radiocarpal level progresses in the later stages of the disease, reconstructive surgery such as partial joint fusion combined with ulnar head resection, total wrist fusion or wrist arthroplasty could be considered. In the event of severe destruction, definitive stabilization by total wrist fusion is indicated. A pain-free, stable wrist joint often outweighs immobility.

A clinical comparison of vertical infraclavicular brachial plexus block using 0.75% or 0.5% ropivacaine for upper limb surgery / 대한마취과학회지

BACKGROUND: We performed a prospective, double blind study to compare the clinical effect of vertical infraclavicular brachial plexus block produced by 0.75% vs 0.5% ropivacaine for upper limb surgery. METHODS: We included 80 patients receiving upper limb surgery under infraclavicular brachial plexus block. The infraclavicular brachial plexus block was performed via the vertical technique with 30 ml of 0.75% or 0.5% ropivacaine. By observation, we determined nerve type was stimulated and scored the level of sensory block and motor block. The quality of blocks was assessed intra-operatively. The duration of sensory block and motor block and their complications were assessed. RESULTS: There were no significant differences in the frequency of stimulated nerve type, evolution of sensory and motor block quality, or success of block. There were no significant differences in the duration of sensory block and motor block. Vascular puncture was noted in 1 patient in the 0.75% ropivacaine. CONCLUSIONS: Both the 0.75% and 0.5% ropivacaine had similar effects in the vertical infraclavicular brachial plexus block.

Continuous epidural analgesia versus continuous intravenous analgesia with peri-articular infiltration following total knee arthroplasty in geriatric patients / 대한마취과학회지

BACKGROUND: Postoperative continuous intravenous analgesia may not provide effective postoperative analgesia following total knee arthroplasty. This study was conducted to determine if combined continuous intravenous analgesia and peri-articular infiltration provided a better quality of analgesia following total knee arthroplasty than epidural analgesia. METHODS: A prospective, double-blind study involving 50 patients who had undergone total knee arthroplasty was conducted. Patients were divided into control group and an experimental group. Patients in the control group (n = 25) received peri-articular infiltration with 47 mL normal saline prior to closure of the wound and postoperative epidural analgesia for 48 hours. Patients in the experimental group (n = 25) received a mixture of peri-articular infiltration of 16 mL of 0.75% ropivacaine, 6 mg morphine, 0.2 mg of epinephrine and 25 mL normal saline prior to closure of the wound and postoperative continuous intravenous analgesia for 48 hours. The analgesic efficacy was then evaluated using the verbal numeric rating scale at 1, 2, 6, 12, 24, and 48 hours postoperatively. The side effects and the dosage of rescue analgesics were then recorded. RESULTS: The experimental group showed a significantly higher pain score than the control group 2 and, 6 hours postoperatively at rest and 2 hours postoperatively following passive knee movement (P < 0.05). In addition, the rescue analgesic requirement was higher for the experimental group during the first 24 hours following surgery than for the control group (P < 0.05). CONCLUSIONS: We found that combined continuous intravenous analgesia and peri-articular infiltration of a mixture of ropivacaine and, morphine injected into the peri-articular tissue provided minimal benefits for pain control during the early postoperative period when compared to epidural analgesia after total knee arthroplasty.

Left Ventricular Outflow Obstruction due to a Left Ventricular Myxoma / 대한흉부외과학회지

Once it is diagnosed, immediate surgical extirpation is desirable for treating left ventricle myxoma that's accompanied with stenosis of the left ventricle outflow tract. This is because this condition may potentially induce fatal complications such as cerebral infarction or myocardial infarction that's triggered by myxoma embolus, or even sudden death due to coronary malperfusion. An 18-year-old male with the chief complaint of NYHA class II exertional dyspnea was found to have a 4x3 cm(2) sized mass on transthoracic ultrasonography, which was shown to move down the left ventricle outflow tract on the systolic phase. The mass was immediately extirpated by incision of the left ventricle; the mass was finally diagnosed as a myxoma. The patient was discharged on at the 10th day postoperatively without any complications. On the 22-month follow-up observation made at the out-patient clinic after discharge, there have been no noticeable, significant changes seen on physical examination or the cardiac ultrasonography.

A Comparison of Epidural Analgesia using 0.1% Levobupivacaine or 0.2% Levobupivacaine Combined with Sufentanil after Major Abdominal Surgery / 대한마취과학회지

BACKGROUND: Continuous epidural analgesia with an opioid-local anesthetic combination is an effective strategy for postoperative pain relief after abdominal surgery. Levobupivacaine, the pure S (-) enantiomer of racemic bupivacaine, is similar to its native agent for anesthetic efficacy but has less cardiotoxic and neurotoxic potential than the bupivacaine. We compared the efficacy and safety of 0.1% levobupivacaine with sufentanil or 0.2% levobupivacaine with the same dose of suentanil for patient-controlled epidural analgesia after major abdominal surgery. METHODS: Forty patients scheduled for major abdominal surgery under general anesthesia were randomized to receive either 0.1% levobupivacaine with sufentanil 0.75microgram/ml (n = 20) or 0.2% levobupivacaine with sufentanil 0.75microgram/ml (n = 20) for postoperative epidural analgesia using a patient-controlled analgesia pump at a rate of 3 ml/h and bolus dose of 2 ml on demand. Visual analogue scale (VAS) pain scores at rest, on coughing, during mobilization from the supine to the sitting position and on ambulation were assessed during 48 hours following the surgery. In addition, degree of motor block and mobilization, additional analgesic requirements and adverse effects were assessed. RESULTS: There were no significant differences in VAS pain scores at rest, on coughing, during mobilization from the supine to the sitting position and on ambulation. There were no significant differences in mean volume of local anesthetic consumption, additional analgesic requirements, degree of motor block and mobilization and the incidence of adverse effects. CONCLUSIONS: 0.1% levobupivacaine with sufentanil provided comparable postoperative epidural analgesia and incidences of adverse effects to 0.2% levobupivacaine with the same dose of suentanil in patients undergoing major abdominal surgery.

Effect of Muscle Relaxants on Short-term Results of Exotropia Surgery: A Focus on Resection Procedures

PURPOSE: We investigated the effect of muscle relaxants (atracurium) on the outcomes of intermittent exotropia surgery under general anesthesia, with a focus on resection procedures. METHODS: Thirty four patients who underwent recession and resection (R&R) were divided into two groups: atracurium usage (group A, n=18) and no atracurium usage (group B, n=16). Patients were divided into two subgroups according to the amount of resection of the medial rectus (MR): less than 5 mm (group 1, n=13) or 5 mm and greater (group 2, n=21). Deviation angles were compared between groups and subgroups. Surgical outcome was defined as successful if distant deviation angles were equal to or less than 10 prism diopters. RESULTS: The overall postoperative deviation angles did not show statistically significant differences between groups A and B. However, in patients with larger MR resections (> or = 5 mm), the 1 week postoperative distant deviation was significantly larger in group A (1.8+/-2.6 PD) than in group B (-1.6+/-4.6 PD, p=0.048 by t-test). The overall undercorrection rate at 3 months postoperatively for group A was 16.7%, which was higher than that of group B (6.3%), and the difference was even larger in subgroups with larger MR resections (> or =5 mm): 18.2% in group A and 0% in group B. CONCLUSIONS: Patients who underwent R&R procedures under general anesthesia with a muscle relaxant tended to be less corrected than those without muscle relaxant, especially in the early postoperative period and with a larger MR resection equal to or greater than 5 mm. However, there was no significant difference in the later postoperative period.

Surgical Treatment for Isolated Aortic Endocarditis: a Comparison with Isolated Mitral Endocarditis / 대한흉부외과학회지

BACKGROUND: Infective endocarditis shows high surgical mortality and morbidity rates, especially for aortic endocarditis. This study attempts to investigate the clinical characteristics and operative results of isolated aortic endocarditis. MATERIAL AND METHOD: From July 1990 to May 2005, 25 patients with isolated aortic endocarditis (Group I, male : female=18 : 7, mean age 43.2+/-18.6 years) and 23 patients with isolated mitral endocarditis (Group II, male : female=10 : 13, mean age 43.2+/-17.1 years) underwent surgical treatment in our hospital. All the patients had native endocarditis and 7 patients showed a bicuspid aortic valve in Group I. Two patients had prosthetic valve endocarditis and one patientsdeveloped mitral endocarditis after a mitral valvuloplasty in Group II. Positive blood cultures were obtained from 11 (44.0%) patients in Group I, and 10 (43.3%) patients in Group II. The preoperative left ventricular ejection fraction for each group was 60.8+/-8.7% and 62.1+/-8.1% (p=0.945), respectively. There was moderate to severe aortic regurgitation in 18 patients and vegetations were detected in 17 patients in Group I. There was moderate to severe mitral regurgitation in 19 patients and vegetations were found in 18 patients in Group II. One patient had a ventricular septal defect and another patient underwent a Maze operation with microwaves due to atrial fibrillation. We performed echocardiography before discharge and each year during follow-up. The mean follow-up period was 37.2+/-23.5 (range 9~123) months. RESULT: Postoperative complications included three cases of low cardiac output in Group I and one case each of re-surgery because of bleeding and low cardiac output in Group II. One patient died from an intra-cranial hemorrhage on the first day after surgery in Group I, but there were no early deaths in Group II. The 1, 3-, and 5-year valve related event free rates were 92.0%, 88.0%, and 88.0% for Group I patients, and 91.3%, 76.0%, and 76.0% for Group II patients, respectively. The 1, 3-, and 5-year survival rates were 96.0%, 96.0%, and 96.0% for Group I patients, and 100%, 84.9%, and 84.9% for Group II patients, respectively. CONCLUSION: Acceptable surgical results and mid-term clinical results for aortic endocarditis were seen.

Surgical Management of Invasive Pulmonary Aspergillosis in Hemtologic Malignancy Patients: Report of 2 cases / 대한흉부외과학회지

The mortality rate of the invasive pulmonary aspergillosis to be able to developed during chemotherapy induced myleosuppressionin is high in hematologic malignancy patients despite antifungal treatment. Effective antifungal treatment combined with operation can decrease the mortaligy rate of the invasive pulmonary aspergillosis. Recently, we experienced the successful management of the two cases of invasive pulmonary aspergillosis in acute lymphoblastic leukemia through effective antifungal treatment and surgical resection. We report this cases with review of literature.

Postoperative Epidural Analgesia using 0.1% Levobupivacaine or 0.1% Ropivacaine Combined with Sufentanil in Gynecologic Surgery / 대한마취과학회지

BACKGOUND: Ropivacaine and levobupivacaine are recently introduced amide local anesthetics that are structurally similar to bupivacaine. In this study, we compared the quality of postoperative analgesia and the side effects of 0.1% ropivacaine/sufentanil and 0.1% levobupivacaine/sufentanil. METHODS: Sixty patients scheduled for gynecologic surgery under general anesthesia were randomized to receive either 0.1% ropivacaine with sufentanil (ropivacaine group) or 0.1% levobupivacaine with sufentanil (levobupivacaine group) for postoperative epidural analgesia using a patient-controlled analgesia pump at a rate of 5 ml/h during the 48 hour period following surgery. Visual analogue scale (VAS) scores at rest and on coughing, sitting and movement, the degree of ambulation, additional analgesic requirements and side effects were assessed. RESULTS: In the levobupivacaine group, VAS scores at rest and on coughing, sitting and movement were lower than in the ropivacaine group (P < 0.05). In the ropivacaine group more patients were able to walk unaided (P < 0.05). There were no differences in local anesthetic consumption, additional analgesic requirements and side effects between the groups. CONCLUSIONS: Both 0.1% ropivacaine with sufentanil and 0.1% levobupivacaine with sufentanil provided effective postoperative epidural analgesia, but ropivacaine produced lesser motor block.

Intralobar Pulmonary Sequestration with Hemoptysis and Hemothorax / 대한흉부외과학회지

A 60-year-old female entered the emergency unit with a chief complaint of hemoptysis. Based on the computer tomographic image analysis of the chest, the patient was diagnosed as having an intralobar pulmonary sequestration that accompanied a hemothorax, and the hemothorax was do to the rupture of a pseudocyst. Pulmonary lobectomy of the left lower lobe and primary closure of an aberrant artery were both performed as an emergency operation. After one week following the operation, the patient was discharged without any postoperative complications.

Antitumor and Antioxidant Activities of the Extracts from Fruiting Body of Phellinus linteus

Fruiting bodies of Phellinus linteus were extracted by hot water and alkali methods. Sugar contents of PL-H (hot water extract) and PL-A (alkali water extract) were 81.1%, 37.4% and protein contents were 6.2%, 21.8%, respectively. Amino acid pattern showed that two extracts contained large amount of aspartic acid and alanine. Two extracts showed characteristic IR absorption pattern for glycosidic bond at 890 cm(-1). PL-H was divided two fractions by gel filtration chromatography and the molecular weights of each fraction were estimated to be about 10 kD and 225 kD, respectively and also PL-A was estimated 10 kD. Two extracts showed strong antitumor, immunomodulating and antioxidant activities, and were compared with commercialized glycopeptide anticancer drugs.

Laparoscopic Nissen Fundoplication and Collis Gastroplasty / 대한흉부외과학회지

The prevalence of gastroesophageal reflux disease has been increased recently in Korea. The use of minimally invasive laparoscopic and thoracoscopic surgery has become popular in the operation of esophageal disease such as esophageal cancer or gastroesophageal reflux disorder. We experienced three cases of laparoscopic Nissen fundoplications and one case of laparoscopic Collis gastroplasty, and we will describe the technical aspect of these surgeries.
