Factors associated with Experience of Diagnosis and Utilization of Chronic Diseases among Korean Elderly : Focus on Comparing between Urban and Rural Elderly / 農村醫學 地域保健

OBJECTIVES@#The purpose of this study was to identify and compare the difference and related factors with general characteristic and health behaviors, a experience of diagnosis and treatment of chronic diseases between rural and urban among elderly in Korea.@*METHODS@#We used the data of Community Health Survey 2017 which were collected by the Korean Center for Disease Control and Prevention. The study population comprised 67,835 elderly peopled aged 65 years or older who participated in the survey. The chi-square test, univariate and multivariate logistic regression analysis were used to analyze data.@*RESULTS@#We identified many significant difference of health behaviors, an experience of diagnosis and treatment with chronic diseases between rural and urban. Compared to urban elderly, the odds ratios (ORs) (95% confidence interval) of rural elderly were 1.136 (1.092–1.183) for diagnosis of diabetes, 1.278 (1.278–1.386) for diagnosis of dyslipidemia, 0.940 (0.904–0.977) for diagnosis of arthritis, 0.785(0.736–0.837) for treatment of arthritis, 1.159 (1.116–1.203) for diagnosis of cataracts, and 1.285(1.200–1.375) for treatment of cataracts. In the experience of diagnosis and treatment of chronic diseases, various variables were derived as contributing factors for each disease. Especially, there were statistically significant difference in the experience of diabetes diagnosis, arthritis diagnosis, cataract diagnosis and dyslipidemia except for hypertension diagnosis (p<0.01) between urban and rural elderly. There were statistically significant differences in the experience of treatment for arthritis and cataract (p<0.01), but there was no significant difference in the experience of treatment for hypertension, diabetes, dyslipidemia between urban and rural elderly.@*CONCLUSION@#Therefore, it would be necessary to implement a strategic health management project for diseases that showed significant experience of chronic diseases with diagnosis and treatment, reflecting the related factors of the elderly chronic diseases among the urban and rural areas.

Result Patterns and Characteristics of HBeAg and HBV DNA in Patients with Chronic Hepatitis B

BACKGROUND: Discrepancies in the results between hepatitis B e-antigen (HBeAg) and hepatitis B virus (HBV) DNA levels pose difficulties in the management of chronic hepatitis B (CHB). This study aims to better understand the different phases of CHB and to detect additional meaningful parameters for CHB patients. METHODS: We collected datasets of HBeAg and HBV DNA levels measured during 2016 and the follow-up results for CHB patients for past 3 years. We analyzed the collected data by applying the definitions of CHB clinical phase and compared the results of semi-quantitative and quantitative HBeAg assays. RESULTS: About 55% of 2,291 result pairs from CHB patients showed qualitative agreement between HBeAg and HBV DNA results. HBeAg (−) CHB was reported in 16.49%, while hepatitis B surface antigen (HBsAg) loss occurred in 0.18% among 1,146 patients annually. HBeAg reversion occurred in 2.74% of 839 patients that experienced HBeAg seroconversion. Patients with HBeAg (+) and HBV DNA (−) showed statistically significant differences in the levels and percentage abnormality of alanine aminotransferase (ALT) based on whether HBV DNA was ‘Target not detected’ or ‘Detected,

Survey and Solutions for the Current Status of Quality Control in Small Hospital Laboratories

BACKGROUND: To prevent medically significant errors, hospital laboratories must perform thorough statistical quality control (QC) procedures. We surveyed the QC status of small laboratories and created new statistical QC software that they can easily use for improving QC. METHODS: A questionnaire on the status of external and internal QC was created and sent to clinics and hospitals with small-scale laboratories. We then created QC software that can be downloaded and installed for free. RESULTS: External quality assessments were performed in 32% of the clinics (22 of 66) and 52% of the hospitals (12 of 23). Seventy-three percent of all institutions (66 of 90) carried out an internal quality assessment based on their own guidelines, mostly using commercialized QC materials. However, only 52% of clinics and 23% of hospitals used their own acceptable range instead of the manufacturer's expected range. In addition, the proportion of manual QC management reached 52% in clinics and 82% in hospitals. The QC software we designed covers all the basic functions of statistical QC and aims to improve the quality of laboratories. CONCLUSIONS: We obtained basic data on the current status of external and internal QC in small-scale laboratories using this survey. Furthermore, we suggested that new QC software may actually help to improve QC of small laboratories.

Decreasing Effect of Lidocaine.HCl on the Thickness of the Neuronal and Model Membrane

This study examined the mechanism of action of a local anesthetic, lidocaine.HCl. Energy transfer between the surface fluorescent probe, 1-anilinonaphthalene-8-sulfonic acid, and the hydrophobic fluorescent probe, 1,3-di(1-pyrenyl) propane, was used to determine the effect of lidocaine.HCl on the thickness (D) of the synaptosomal plasma membrane vesicles (SPMV) isolated from the bovine cerebral cortex, and liposomes of the total lipids (SPMVTL) and phospholipids (SPMVPL) extracted from the SPMV. The thickness (D) of the intact SPMV, SPMVTL and SPMVPL were 1.044+/-0.008, 0.914+/-0.005 and 0.890+/-0.003 (arbitrary units, n=5) at 37degrees C (pH 7.4), respectively. Lidocaine.HCl decreased the thickness of the neuronal and model membrane lipid bilayers in a dose-dependent manner with a significant decrease in the thickness, even at 0.1 mM. The decreasing effect of lidocaine.HCl on the membrane thickness might be responsible for some, but not all of its anesthetic action.

Palliative Care of Malignant Ureteral Obstruction with Polytetrafluoroethylene Membrane-Covered Self-Expandable Metallic Stents: Initial Experience

PURPOSE: We assessed the efficacy and safety of insertion of a polytetrafluoroethylene membrane-covered self-expandable metallic stent (UVENTA stent) for palliation of malignant ureteral obstruction on the basis of our early results. MATERIALS AND METHODS: Eighteen patients underwent UVENTA stent insertion for extrinsic malignant ureteral obstructions of 20 ureters. The UVENTA stents were deployed retrogradely under cystoscopy and fluoroscopy. Candidates for the procedure had preexisting double-J stents that were nonfunctional or caused excessive bladder irritation. We recorded the success and patency rate in addition to any complications associated with the procedure. RESULTS: The mean length of obstruction was 10.6 cm (range, 2 to 20 cm). Two ureters were obstructed in the upper ureter, 9 in the lower ureter, and 9 in multiple levels of ureter. Simultaneous balloon dilation was performed in 12 ureters. UVENTA stents were successfully inserted in all patients. No obstruction of the UVENTA stents occurred during the mean follow-up period of 7.3 months (patency rate 100%), but de novo ureteral obstruction developed in 4 ureters. There were no instances of stone formation, hyperplastic reaction, encrustation, or migration. Abnormally elevated serum creatinine decreased to normal levels and hydronephrosis gradually resolved during the 4 weeks after UVENTA insertion. No significant complications developed except for transient and self-limiting hematuria and mild lower abdominal pain. CONCLUSIONS: UVENTA stents may relieve malignant ureteral obstruction safely and easily. Long-term follow-up is necessary to assess the role of this stent in the treatment of malignant ureteral obstruction.

Progression of Prostate Cancer Despite an Extremely Low Serum Level of Prostate-Specific Antigen

A 61-year-old man who had been diagnosed with prostate cancer 9 years ago and had been treated with pelvic irradiation and intermittent androgen deprivation therapy visited the emergency room because of back pain and weakness in both legs. Spine magnetic resonance imaging showed a lumbar epidural mass and spine metastasis. The whole-body workup revealed multiple metastases to the lymph nodes, bone, liver, and lung. The serum prostate-specific antigen was 0.02 ng/ml. He underwent laminectomy, posterior fixation, and epidural mass excision, and metastatic adenocarcinoma from the prostate was diagnosed. The patient underwent 1 cycle of docetaxel-based chemotherapy. More chemotherapy could not be done because of his general weakness. The patient died one month later of multiple organ failure.

Two Episodes of Stenotrophomonas maltophilia Endocarditis of Prosthetic Mitral Valve: Report of a Case and Review of the Literature

Stenotrophomonas maltophilia (previously named Xanthomonas maltophilia) is an aerobic, non-fermentive, Gram-negative bacillus that is wide spread in the environment. It was considered to be an organism with limited pathogenic potential, which was rarely capable of causing diseases in human other than those who were in debilitated or immunocompromised state. More recent studies have established that Stenotrophomonas maltophilia can behave as a true pathogen. Endocarditis due to this organism is rare, and only 24 cases of Stenotrophomonas maltophilia endocarditis have been reported in the medical literature. Most cases were associated with risk factors, including intravenous drug abuse, dental treatment, infected intravenous devices, and previous cardiac surgery. We present a case with two episodes of Stenotrophomonas maltophilia endocarditis after mitral valve prosthesis implantation, which was treated with antibiotics initially, and a combination of antibiotics and surgery later. To our knowledge, this is the first case of repetitive endocarditis due to Stenotrophomonas maltophilia.

Systemic lupus erythematosus complicated with cerebral venous sinus thrombosis: a report of two cases

A rare manifestation of systemic lupus erythematosus (SLE) is cerebral venous sinus thrombosis (CVST), in which early diagnosis and aggressive therapy are of prime importance for favorable outcome. The pathogenesis of CVST is largely unknown, but it is thought to be caused by cerebral vasculitis, antiphospholipid antibodies or other conditions associated with enhanced coagulability. We describe two cases of SLE with CVST which were not associated with antiphospholipid antibodies. Both cases were treated with immunosuppressants (intravenous methylprednisolone and cyclophosphamide pulse therapy) and anticoagulant drugs (heparin and subsequent maintenance therapy with warfarin). There was a marked improvement of neurologic symptoms with the disappearance of thrombus in a follow-up MRI. The possibility of CVST should be considered in any patients with SLE who show neuropsychiatric manifestations.

Ambulatory Hemorrhoidectomy under Local Anesthesia

PURPOSE: Hemorrhoidectomy can be associated with severe pain in the immediate postoperative period. The aim of this study was to evaluate the advantages and feasibility of hemorrhoidectomy under local anesthesia (pudendal nerve block). METHODS: From september 1998 to August 2000 we performed 77 hemorrhoidectomy with local anesthesia in our Colorectal unit under the ambulatory surgery regimen. 0.5% lidocaine and 0.25% bupivacaine mixed by 1:1 ratio were used for pudendal nerve block and local anesthesia. RESULTS: Using pudendal nerve block, ambulatory hemorrhoidectomy with or without band ligation were done in 77 patients. Male to female ratio was 46:31, mean age was 35.2 years. 3 major piles plus 1 minor pile were present in 40 patients (51.9%). We injected mixed lidocaine and bupivacaine solution through external sphincter and puborectalis muscle. All patients were successfully operated without conversion to general anesthesia or even intravenous anesthetic injection. Postoperative pain of them were compared the patients who were operated hemorrhoidectomy under general (spinal or caudal) anesthesia during the same time. The pain were assessed using verbal rating pain scale at 24 hours, 48 hours and 72 hours (1-10, where 1 presented no pain and 10 represented the worst pain imaginable) by phone call examination. Mean pain scores for pudendal anesthesia group at 24, 48, 72 hours were 5.32, 3.07 and 2.21, respectively, compared with other anesthesia group with 6.47, 4.52 and 3.24. These differences were statistically significant (P value<0.05). Post operative pain was successfully controlled with home care and oral medications. CONCLUSIONS: Under local anesthesia with pudendal nerve block, ambulatory hemorrhoidectomy were able to decrease pain and urinary retension in comparison to spinal or caudal anesthesia group. Ambulatory hemorrhoidectomy is useful, low cost and feasible.

Clinical Significance of CEA Level of Peripheral Vein, Inferior Mesenteric Vein, Bile, and Peritoneal Fluid in Sigmoid Colon and Rectal Cancer

Carcinoembriogenic antigen (CEA) was widely used as a marker for staging and detection of recurrence and metastases, and evaluation of response of radical opertion or chemotherapy in colorectal cancer patients. METHODS: We examined 50 patients with sigmoid colon and rectal cancer patients who had a radical operation between 1994 May and 1995 April. We checked the level of CEA of peripheral blood preoperatively and postoperatively, and inferior mesenteric vein, bile of gall bladder and peritoneal fluid during surgery. We review clinical characters of the patients, and analyzed the importance of CEA level. RESULTS: The mean CEA levels of peripheral blood (postoperation), inferior mesenteric vein, bile, peritoneal fluid were 5.35+/-2.65, 13.23+/-2.13, 9.23+/-1.65, 7.42+/-2.34 ng/ml respectlively. The mean CEA level of inferior mesentiric vein (13.23+/-2.13 ng/ml) was significantly higher than that of preoperative peripheral blood (8.13+/-2.34 ng/ml) (p<0.05). Falling of postoperative peripheral blood CEA level was also significantly lower than that of preoperative level (p<0.05). CONCLUSIONS: Level of postoperative peripheral blood was related to recurrence rate and survival rate, but tumor size, tumor location, tumor differentiation, Dukes' stage were not related to the CEA level. Bile and peritoneal fluid CEA levels were related with the liver metastasis or local recurrence respectively. We suggest that CEA was useful indicator for evaluation, management, and prognosis of colorectal cancer not only preoperatively but also postoperatively.

Clinical manifestations of amanita subjunquillea poisoning / 대한내과학회지

BACKGROUND: To the best of our knowledge, the report on Amanita subjunquillea poisoning has not been found in the medical literature. We investigated the clinical aspects of Amanita subjunquillea poisoning. METHODS: Sixteen subjects who had ingested the mushroom (A. subjunquillea) were examined for clinical features, laboratory and radiologic findings prospectively. RESULTS: The mean incubation period was 11.5 hours(range: 3 to 17 hours). The initial presentations were gastrointestinal symptoms which persisted for 2 to 4 days. The transaminase levels were elevated in all subjects and peaked on day 3 after ingestion of the mushrooms (mean AST/ALT levels : 3241 IU/L and 3741 IU/L, respectively). Biochemical evidence of pancreatitis and disseminated intravascular coagulation were frequent (83.3% and 62.5%, respectively). Liver ultrasonography and scintigraphy revealed abnormalities in most cases. Massive hepatic necrosis was confirmed by liver biopsy in one subject. The overall mortality was 12.5%. CONCLUSION: Clinical manifestations of A. subjunquillea poisoning were similar to those of other poisonous Amanitaceae intoxication. However, the mortality rate was lower in A. subjunquillea poisoning. Our data showed strong evidence that A. subjunquillea should be classified in the group of poisonous mushrooms.

A Study on the Effect of the Combined Use of Gentle Ventilation and High-requency ntilation on the Incidence of Chronic Lung Disease

PURPOSE: This study was conducted to determine the correlation between the incidence of chronic lung disease and the combined use of gentle ventilation and high-frequency ventilation. METHODS: The subject group consisted of 63 very low birthweight infants of less than 1500gm who were born and survived through ventilator treatment in the Fatima neonatal intensive care unit for four years from January 1995 to December 1998. The analysis was performed retrospectively with medical records. Ventilator treatment was based on the combined use of gentle ventilation and high-frequency ventilation by means of the flow interruptor type of Infant star. High- frequency ventilation was carried out for 24 hours after surfactant replacement, when PaCO2 exceeded 60mmHg, or if the period of gentle ventilation exceeded one week. When the results of arterial blood gas analysis and the state of the body became stable, the aggressive weaning was performed. RESULTS: For 49(77.8%) of 63 infants, the weaning was possible within seven days. The other 14 infants(22.2%) needed ventilator treatment for more than seven days. The mean duration of ventilator treatment was 12.3 days. The causes of weaning failure included sepsis, patent ductus arteriosus, chronic lung disease, and intraventricular hemorrhage. Two infants who had received ventialtor treatment for more than two weeks were found to have incidence of chronic lung disease. CONCLUSION: It is suggested that the combined use of gentle ventilation and high-frequency ventilation can help reduce pulmonary damage, and it will be important to shorten the period of ventilator treatment.

A Case of Behcet's Disease Complicated with Deep Vein Thrombosis and Cerebral Venous Sinus Thrombosis / 대한류마티스학회지

Behcet's disease is a multisystemic disease, in which vascular involvement occurs in 7. 7-60% of patients. There are three forms of vascular involvement such as venous occlusion, arterial occlusion and arterial aneurysm. Venous lesions are more common than arterial lesions and the common sites of venous thrombosis are inferior vena cava, superior vena cava, and superficial or deep veins of extremities. Thrombosis of cerebral venous sinus is an infrequent complication of Behcet's disease and it seems to be rare that both deep vein thrombosis and cerebral venous sinus thrombosis occured at the same time. We experienced a case of Behcet's disease complicated with thromboses of left common femoral vein and right transverse sinus. A 29-year-old man presented with persistent dull nature headache, nausea, vomiting, blurred vision and left lower leg swelling. Duplex ultrasonography of lower extremity showed thrombus in the left common femoral vein. Magnetic resonance imaging of brain showed isodense signal intensity lesions in right transverse sinus on Tl weighted image. On magnetic resonance angiography, the right transverse, sigmoid sinus and right internal jugular vein were not visualized. The patient showed substantial improvement after treatment with steroid, cyclosporine A and anticoagulants.

A Case of Early Developed Left Ventricular Free Wall Rupture Followed by Acute Inferior Myocardial Infarction

Myocardial free wall rupture is the most serious complication of acute myocardial infarction. Although it is not uncommon, it is difficult to treat successfully. We report a case of acute inferior myocardial infarction complicated with left ventricular free wall rupture that occurred 8 hours after onset of chest pain. In this case, progression of mild pericardial effusion to cardiac tamponade was monitored by transhtoracic echocardiography. Pericardiocentesis and draninage failed to treat cardiac tamponade, and surgical repair was performed successfully. The patient discharged uneventfully on 28th day and followed regularly at the outpatient department.

A Case of Methimazole-Induced Cholestatic Jaundice with Steroid Therapy / 대한내분비학회지

Cholestatic jaundice caused by imidazole derivatives is a rare complication of antithyroid drug therapy. We present a case of cholestatic jaundice with systemic hypersensitivity reaction, which developed in a 27-year old male one day after exposure to methimazole. The patient showed clinical improvement and gradual resolution of jaundice after the discontinuation of methimazole and treatment with prednisolone. Histologic findings of liver revealed bile pigment, predominantly in centrilobular area, and infiltration of chronic inflammatory cells in a few portal area without evidence of degeneration or necrosis of hepatocytes. Methimazole could be presumed as etiologic agent from clear chronological relationship and the lack of other causative factors. We report this unusual case with review of literature.

A Case of Early Gastric Carcinoma Combined with Hypereosinophilic Multiple Liver Abscesses / 대한소화기내시경학회지

Eosinophilia is defined as the presence of more than 500 eosinophil/mL of blood and is common in the clinical condition such as parasite infestation, drug, allergy, hypereosinophilic syndrome, and malignant diseases. Determining the cause of eosinophilia may be one of the most frustrating endeavors in clinical medicine. Hepatic infiltration of eosinophils and microabscess formation are observed in many disorders. Gastric cancer and intestinal malignancies show frequent liver metastasis and blood eosinophilia. Several cases of an early gastric carcinoma (EGC) with metastasis of the liver have been reported. When multiple intrahepatic lesions of suspicious malignancy appear in radiologic study, clinicians must differentiate malignancy from benign diseases. A case is herein reported of a 56- year-old male patient with synchronously developed, multiple low density hepatic lesions with early gastric carcinoma. He was managed with systemic chemotherapy at another hospital, because he was diagnosed with distant metastasis of early gastric carcinoma. Upon operating these lesions were proved to be EGC combined with hypereosinophilic multiple liver abscesses. This case is herein reported with a review of relevant literatures.

A Case of Spontaneous Rupture of REnal Allograft / 대한신장학회잡지

Spontaneous renal allograft rupture is an uncommon complication of renal transplantation, but it represents a life-threatening emergency that requires prompt recognition and treatment. The incidence of spontaneous renal allograft rupture is variable and range between 3.6 and 9.6 percent of all transplants. In the majority of cases the rupture is associated with acute rejection episodes and with renal vein thrombosis. Most frequently, the allograft rupture occurs within the first 2 weeks of transplantation. in addition, most ruptures reported have occurred in cadaveric renal allograft. Debate on the management of such allograft salvage versus transplant nephrectomy. It appears that the recent trend is toward performing surgical repair of the graft if the rupture is secondary to rejection and oo evidence of renal vein thrombosis ; otherwise, graft nephrectomy be done. We report a case of spontaneous renal allograft rupture due to renal vein thrombosis occurred in a 21-year-old woman 6 days after transplantation. Unusual severe localized pain, swelling over at allograft site, and hypotension, a triad frequently seen in renal allograft rupture, were present. Management by graft nephrectomy was inevitable because of the patient's downhill course.

Rheumatoid arthritis associated with myelodysplastic syndrome: a case report

Myelodysplastic syndromes (MDS) are a group of refractory anemias resulting from a clonal stem cell disorder often associated with cytogenetic abnormalities. There is increasing recognition of immunological abnormalities in patients with MDS, including defective B- and T-cell function, hyper- or hypogammaglobulinemia and monoclonal gammopathy. MDS have been associated with Sjogren's syndrome, polymyalgia rheumatica, relapsing polychondritis and systemic lupus erythematosus. Although there may be various rheumatologic features, including acute arthritis in MDS, chronic inflammatory arthritis is uncommonly combined. There have been a few reports that described cases of rheumatoid arthritis (RA) concurrent with MDS, but advanced rheumatoid arthritis with typical joint deformities has rarely been reported. We report a case of rheumatoid arthritis with atlantoaxial subluxation combined with refractory anemia in a 31-year-old woman.

A Case of Obstructive Jaundice Caused by Cavernous Transformation of the Portal Vein / 대한소화기내시경학회지

Cavernous transformation of the portal vein is a rare condition probably arising secondary to extrahepatic portal vein thrombosis or obstruction with recannalization and/or collateral veins formation to bypass the obstruction. It is believed that cavernous transformation of the portal vein is caused by a variety of diseases associated with periportal collateral development and hepatopedal flow. It is known that portal vein occlusion, which is the actual cause of cavernous transformation, has a wide variety of etiologies, such as congenital abnormalities, omphalitis, pancreatitis, various carcinoma, and liver cirrhosis. In most cases, the revealing symptom is upper gastrointestinal bleeding. Rarely, however, diagnosis is made from obstructive jaundice. Extensive collateral veins due to portal vein occlusion may compress and narrow the biliary tract. A 39-year-old man was admitted due to jaundice and abdominal discomfort for 1 month. He was confirmed to have obstructive jaundice due to collateral vessels of cavernous transformation of the portal vein. We report a case of obstructive jaundice caused by cavernous transformation of the portal vein.
