A 15 kg 6-year-old intact male Jindo dog with a history of a respiratory distress, hindlimb paralysis with necrosed skin of dorsal digit for three weeks was referred to Animal Medical Center, Chonbuk National University. Heartworm infection was identified by kit examination. In plain thoracic radiographs, dilated pulmonary arteries reverse D sign and focal interstitial pattern was compatible with heartworm infection and possible pulmonary thromboembolism. Abdominal radiographs showed poor serosal detail indicating fluid accumulation within peritoneal cavity. No evidence of musculoskeletal abnormalities was found. Ultrasonography presented focal wedge-shaped hyperechogenecity on the both poles of left kidney, weak or absent pulse on the distal to the external iliac artery as well as ascites and irregular liver margin. Multi-organ failure was strongly supposed by blood profile including leukocytosis, anemia, hemoglobinuria bililubinemia, hypoalbuminemia, imbalance of electrolytes, and increased hepatic and renal function values. Interestingly, the glucose level is remarkably lower in pelvic limb compared to thoracic limb. Suspected pulmonary thromboembolism, renal infarction and femoral arterial embolization causing hindlimb paralysis and dermatic necrosis were confirmed by 3D reconstructed CT imaging. Prior to taking a consideration of euthanasia, interventional radiology was experimentally attempted but failed due to not recovered from general anesthesia. Early and accurate diagnosis of thromboembolism is valuable and 3D reconstructed CT images might be very useful to show the correct way to treat effectively.

Background: Conservation of blood during cardiac surgery is important because of the shortage of donor blood, risks associated with transfusion, and the costs of allogeneic blood products. This retrospective study explored the feasibility of off-pump coronary artery bypass (OPCAB) without transfusion. Methods: One hundred and two consecutive patients underwent OPCAB from January 2007 to June 2012 at Hallym University Sacred Heart Hospital. Excluding 10 chronic renal failures patients, 102 patients were enrolled. Their characteristics, clinical data, and laboratory data were analyzed. We investigated the success rate of OPCAB without transfusion according to preoperative hemoglobin (Hb), and the cutoff point of the Hb level and the risk factors for transfusion. We implemented multidisciplinary blood-saving protocols. Results: The overall operative mortality and the success rate of OPCAB without transfusion were 2.9% (3/102) and 73.5% (75/102). The success rates in patients with Hb<11, 11 70 years, diagnosis of acute myocardial infarction, preoperative Hb and creatinine levels, and operation time. The events precipitating the need for transfusion were low Hb level in 9 patients and hypotension or excessive bleeding in 18 patients. Conclusion: The preoperative Hb level of >11 facilitates OPCAB without transfusion. These results suggest that transfusion-free OPCAB can be performed by modifying the risk factors and correctable causes of transfusion and improving various blood salvage methods.

Purpose: To improve professional intensive care by analyzing admission causes, causes of death, disease conditions, and treatment processes in patients with hematological malignancies admitted to intensive care units (ICUs) in South Korea. Methods: This was a retrospective study approved by IRB, and conducted on admission with 559 adults, in the hematology ICU of a hospital located in Seoul. The study was carried out from April 2009 to March 2012. Data were analyzed using SAS. Results: Pneumonia was the most frequent cause of ICU admission and death, followed by sepsis. The condition at discharge was death (53.6%), recovery (39.9%), or hopeless (5.1%). Mortality of patients in states of incomplete remission was higher than that of patients with complete remission and of patients with multiple myeloma, severe aplastic anemia, and lymphoma. Conclusion: Results show that pneumonia and sepsis are the most frequent causes of ICU admission and for the death of patients with hematological malignancies. The most frequent status at discharge of patients with hematological malignancies was death (53.6%), with mortality of patients at Incomplete Remission status, of mechanically ventilated patients, and of patients on continuous renal replacement therapy (CRRT) being higher than others.

The aim of this study was to evaluate double-pigtail ureteral stent fixation in cats. Medical records of 19 cats (23 ureters) with complete ureteral obstruction that double-pigtail ureteral stent placement were carried out were retrospectively reviewed. The cats were randomly classified into two groups; 13 cats (16 ureters) with double-pigtail ureteral stent fixed to urinary bladder (SF group) and 6 cats (7 ureters) with not fixed to urinary bladder (SNF group). The average age and weight of the cats was 7.4 years and 3.73 kg, respectively. Postoperative complications included chronic renal failure (n = 11), lower urinary track diseases (cystitis, hematuria, pollakiuria) (n = 7), stent migration (n = 6), anemia (n = 5), ascites (n = 2), hyperthermia (n = 1), enteritis (n = 1), oliguria (n = 1), hypotension (n = 1), ureteritis (n = 1), and pyelonephritis (n = 1). Stent migration did not occur in the 16 ureters of the cats in SF group but did occur in 4 out of 7 ureters of the cats in SNF group. The prevention of stent migration by stent fixation was significant (P = 0.04). Among the 13 cats in SF group, only 2 cats developed lower urinary track diseases, while 4 of the 6 cats in SNF group showed symptoms of lower urinary track disease. Thus, the cats that underwent double-pigtail ureteral stent fixation to the urinary bladder developed significantly fewer lower urinary diseases (P = 0.046). In conclusion, double-pigtail ureteral stent fixation to the urinary bladder for treatment of complete ureteral obstruction in cats can effectively prevent stent migration, which is common complication of stent placement.

Hemolytic uremic syndrome (HUS) is a rare disorder characterized by the triad of microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure. HUS arises from a wide spectrum of conditions, and chemotherapeutic agents have been reported to be associated with HUS, including Mitomycin, Cisplatin, Bleomycin, and Gemcitabine. A 76-year-old man treated with Gemcitabine due to non-small cell lung cancer developed clinical and laboratory findings compatible with HUS. Gemcitabine was ceased and hemodialysis and plasma exchange were utilized and he recovered. A high level of suspicion for HUS is necessary when cancer patients are treated with Gemcitabine, and prompt recognition and treatment are also essential.

Yang deficiency pattern is a representative syndrome differentiation. This article is a study on to which categories of modern diseases yang deficiency is assigned by reference to modern clinical papers and the meaning of yang deficiency interpreted with a perspective of Korean Medicine and a modern perspective. Yang deficiency, yang qi deficiency, lack of yang qi and yang qi debilitation are the words found in "Nei Ching" and yang qi can be interpreted as something to warm, drive and arouse. Zhangzhongjing considered recovery or loss of Yang as the key to life in "Shanghanlun". Danxi proposed "Yang being liable to hyperactivity, Yin being insufficient" and emphasized pathological ministerial fire of Yang exuberance rather than physiological ministerial fire of Yang deficiency. Zhangjingyue proposed "Yang not being in excess, Yin being often deficient" and understood growth and decline of yin qi are all led by yang qi and put emphasis on true yin in addition to yang qi. Diseases of yang deficiency pattern are related with decline of metabolic level, hypofunction of internal secretion, disorder of immune function, disorder of automatic nerve system, sympathetic nerve inhibition, metabolic disorder of microelements, increase of cGMP, change of microcirculation, low speed of blood stream, kidney malfunction. Diseases related with kidney are sterility, polycystic ovary syndrome, spinal stenosis, edema, renal failure, IgA nephropathy, erectile dysfunction, nephritis, prostatitis, benign prostatic hyperplasia, decrease of adrenal cortical hormone by nephrotic syndrome, myelodysplastic syndrome. Disease related with heart are heart failure, arrhythmia, cardiomyopathy, atherosclerosis heart disease, hypertension, hyperlipidemia, pulmonary heart disease. Diseases related with spleen are irritable bowel syndrome, ulcerative colitis. Diseases related with liver are hypothyroidism, liver cirrhosis ascites, hepatitis B, chronic hepatitis, hepatic diabetes. Diseases related with lung are allergic rhinitis, cough variant asthma, bronchial asthma, pulmonary emphysema. And diabetes mellitus, metabolic syndrome, aplastic anemia, headache, encephalatrophy, Alzheimer's disease are also related with yang deficiency.

For the estimation of prevalence state of major chronic adult disease and their relationships with drinking and smoking habits in the Korean employees, we analyzed a medical check-up data of 155,799 subjects that was accumulated during the year of 2008. In age and sex distribution of the sample, male subjects were 106,229 and female 51,827 showing the ratio of 2:1 and the majorities were 30s and 40s covering 70.7% of the total. The prevalence rates of major chronic diseases were obesity 29.8% (male 38.3%, female 12.3%), hypertension 4.1%, HBV carrier inactive 3.3%, diabetes mellitus 2.9%, hypothyroidism 1.7% (male 1.3%, female 2.4%), hyperlipidemia 1.1%, hyperthyroidism 1.4% (male 1.1%, female 2.1%), osteoporosis 1.4% (male 1.4%, female 1.4%), anemia 0.9% (male 0.3%, female 2.0%) and renal disease 0.9%. The frequency of and volume of drinking in male group were 4.6 times and 7.5 times higher than female group respectively. The 33.8% of the workers were smoking currently. In the serological tests, all the items such as AST, ALT, ${\gamma}-GTP$, LDH for liver function, Cholesterol, TG, uric acid for hyperlipidemia and BP systolic, Fasting blood sugar, BMI for metabolic syndrome were significantly higher in the more drinking and more smoking groups than other groups (p<0.001). The higher prevalence rates in male group in the liver disease seems to be strongly related with the drinking and smoking habits in male employees. We suggest that employees should rather relying on leisure or hobbies than drinking and smoking for the stress relief.

DA-3585, a biosynthetic recombinant human erythropoietin has been developed as a treatment for anemia associated with chronic renal failure in Dong-A pharmaceutical Co. Ltd. This study was carried out to assess its acute and subacute toxicities in rabbits. DA-3585 was intravenously administered to rabbits at dose levels of 6250, 12500 or 25000 lU/kg for single dose toxicity study and at dose levels of 100, 500 or 2500 lU/kg/day for 4-week repeated dose toxicity study. In the acute toxicity study, dose up to 25000 lU/kg had no adverse effect on the behavior or body weight gain. Pathological examinations revealed no abnormal gross lesions related to DA-3585. In the subacute toxicity study, all animals survived until termination of treatment. DA-3585 had no influence on clinical signs, food and water intake or on body weight changes. Hematological examination showed increases in the number of RBC, hemoglobin contents and hematocrit values with a dose dependent manner in the animals treated with DA-3585. Histopathological examination revealed erythroid hyperplasia in the bone marrow and extramedullary hematopoiesis in the liver. The changes detected in the hematological and histopathological examination presumably represent exaggerated pharmacological effects of erythropoietin. The NOAEL (no-observed-adverse-effect-level) of DA-3585 was estimated to be 100 lU/kg/ day under this study condition.

Objectives: The purpose of this study is to report the effect and safety of traditional Korean medicine (TKM) for enhanced recovery after surgery (ERAS) after gynecological surgery. Methods: The study is conducted by analyzing the medical records of the hospitalized patients in TKM hospital. Eighty-six patients were enrolled who received TKM for ERAS after gynecological surgery from January 2015 to April 2018. We performed statistical analysis by using SPSS ver. 25.0. To prove the effect and safety of TKM for ERAS, we analyzed symptoms and Hemoglobin (Hb), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and serum creatinine (Cr) with glomerular filtration rate (GFR). In addition, we checked other adverse reactions that the patients complained to prove the safety of TKM for ERAS. Results: Among symptoms of pain, there was a statistically significant decrease in abdominal pain, lower back pain, and shoulder pain. Other symptoms showed statistically significant improvement in fatigue, abdominal tympanosis, operation-site discomfort, dizziness, urinary discomfort, throat discomfort, constipation, dyspepsia and colporrhagia. Anemia in both ferritin combination treatment group and herbal medicine only group showed significant improvement. There was no liver damage or renal damage by TKM. Conclusions: The result has shown that TKM for ERAS after gynecological surgery is effective and safe. The further study of TKM for ERAS with more patients is needed.

Purpose: The purpose of this retrospective study was to investigate the relationships of types of dental insurance coverage in Korea with sociodemographic characteristics and the prevalence of systemic and oral diseases, as well as to evaluate the socioeconomic impact of Korean dental insurance policies. Methods: Sample cohort data from 2006 to 2015 were obtained from the National Health Insurance Service. Patients were divided into 2 groups. The exposed group comprised patients who received insurance benefits for complete dentures, removable partial dentures, and implant care, while the control group comprised patients who did not receive these benefits. The type of insurance coverage and the prevalence of systemic and oral diseases were compared between the 2 groups. Results: Patients who received benefits in the form of complete dentures, removable partial dentures, and implants had similar sociodemographic characteristics in terms of sex, age, income quintile, and type of insurance coverage to the control group. The prevalence of hypertension, anemia, renal disease, rheumatoid arthritis, osteoporosis, asthma, and cerebral infarction was higher in the exposed group than in the control group (P<0.05). The prevalence of periodontal diseases and dental caries was also higher in the exposed group. Conclusions: Korean dental health insurance policy has been beneficial for the medical expenses of low-income and elderly people suffering from a cost burden due to systemic diseases. However, since there is a tendency to avoid invasive interventions in older patients due to the high risk of systemic diseases, insurance coverage of dentures may be more helpful from a socioeconomic perspective than coverage of dental implant treatments.
