The Landsteiner–Wiener (LW) antigen is a type of red blood cell antigen. Anti-LW appears in various situations, including alloantibodies, autoantibodies, and even transiently occurring antibodies. Anti-LW has similar characteristics to anti-D, so it can interfere with interpreting pre-transfusion tests and finding compatible blood. This paper introduces three cases in whom anti-LW was detected through antibody identification tests. All three cases were examined using the column agglutination technique with ID-DiaPanel (Bio-Rad, Hercules, CA, USA) on a LISS/Coombs card, ID-DiaPanel p (Bio-Rad) on a NaCl/Enzyme card, and ID-DiaPanel (Bio-Rad) on a LISS/Coombs card using red blood cells treated with dithiothreitol. The auto-control test, direct antiglobulin test, and umbilical cord blood test were also performed. In all three cases, the reaction with D-positive panel cells was stronger than that with the D-negative panel cells, and two of them showed a pan-agglutinated reaction in ID-DiaPanel p (Bio-Rad) with NaCl/Enzyme card. They were reported as anti-LW, and as in these cases, anti-LW can occur under a range of conditions and interfere with proper transfusion. Therefore, it is important to identify anti-LW accurately, and if anti-LW is present, the transfusion of D-negative ABO matched blood should be recommended because of the low expression of the LW-antigen. On the other hand, D-positive blood is not a contraindication when an urgent transfusion is needed.

Coronary artery disease remains the leading cause of early death and graft loss in renal transplant patients. The aim of this study was to identify clinical and echocardiographic parameters independently associated with the angiographically-determined severity of coronary atherosclerosis in long-term kidney transplant patients. Fifty-two kidney transplant recipients who underwent elective coronary angiography were reviewed retrospectively. Angiographic severity was evaluated using the modified Gensini index (MGI). The mean age at coronary angiography was 52.5+/-7.9 yr with a mean prior transplant duration of 118.1+/-58.8 months. Pearson correlation analysis demonstrated a positive correlation of MGI with transplant duration before coronary angiography and chronic allograft nephropathy, whereas an inverse correlation was demonstrated with ejection fraction and statin use. On subsequent multivariate linear regression analysis, transplant duration before coronary angiography, statin use, and ejection fraction were independently associated with the severity of coronary atherosclerosis in long-term kidney transplant patients. In summary, our study demonstrates that statin use, ejection fraction, and transplant duration before coronary angiography are independent parameters associated with the severity of coronary atherosclerosis in long-term kidney transplant patients. Further investigation is required to reduce the atherosclerotic burden in kidney transplant patients.

OBJECTIVES: To evaluate the blood and urinary cadmium concentration levels of around abandoned metal mines in comparison with a control group. METHODS: Blood and urinary cadmium concentration levels were analyzed through investigations of the dietary habits and dietary water of subjects living near abandoned metal mines (exposure group) (n=190) in comparison with those living in designated control areas (control group) (n=256). RESULTS: The blood cadmium (1.93 microgram/l) and urinary cadmium (2.41 microgram/g cr) concentrations of the exposure group were significantly higher than those of the control group (blood cadmium: 1.19 microgram/l, urinary cadmium: 1.94 microgram/g cr). Both concentrations were significantly higher in vegetarians in both groups. CONCLUSIONS: The exposure group had higher blood and urinary cadmium concentrations than the control group. We attributed the elevated blood and urine cadmium levels in the abandoned mine residents to the influence of the abandoned mine sites.

PURPOSE: The ultrasonography (USG) and computed tomography (CT) are popular diagnostic tools for the diagnosis of acute appendicitis in children, but there are many debates about their clinical significance. The purpose of this study is to clarify the clinical significance of USG, CT and follow-up CT performed subsequently to USG, especially in perforated acute appendicitis in children. METHODS: We have reviewed 419 cases of surgically confirmed acute appendicitis in children under the age of sixteen, who had been treated in Inje University Ilsan Paik Hospital from March 2002 to February 2006. All the clinical data including the results of USG and CT were collected and analyzed. RESULTS: Sensitivity, specificity, positive and negative predictive values of USG were 98.7%, 96.8%, 98.1%, 97.8% in non-perforation group and 90.8%, 100%, 100%, 81.9% in perforation group. Those of CT were 96.4%, 100%, 100%, 96.5% and 86.6%, 100%, 100%, 87.5% respectively. Those of follow-up CT after USG were 100%, 100%, 100%, 100% and 87.5%, 100%, 100%, 92.0% respectively. The duration of using antibiotics in seven patients showed positive correlation with the interval between two imaging studies (r=0.0472, p=0.019). There was no statistical significance of correlation when these imaging studies performed within 30 hours together. CONCLUSION: In most of the cases, single choice between USG and CT would be enough to diagnose the acute appendicitis in children. But, it may be helpful to perform CT as early as possible subsequently to USG when there is discrepancy between initial USG and clinical impression.

BACKGROUND AND OBJECTIVES: Protein kinase plays an important role in transmembrane signalling, which is modulated by cellular transduction by second messengers such as inositol-1, 4, 5-triphosphate (IP3), Diacylglycerol (DG), cAMP, to express biological activity by stimulation of hormones, neurotransmitters, antigens, growth factors. Protein kinase Cs participate in signal transduction of cell, secretion of neurotransmitter, regulation of ion conduction, exocytosis, gene expression and cellular proliferation. Also, it raises slow motility by Na+-H+ exchange (NHE) and Ca2+ channel in the outer hair cells. It may also be involved in mechanical transduction, cellular proliferation and reproduction in supporting cells, and in producing endolymphs using the KCNE1 and Na+/K+-ATPase in the lateral wall of cochlea. MATERIALS AND METHOD: We investigated the immunoreactivities of the PKC (alpha, beta, gamma, delta) via paraffin section and surface preparation of the cochlea of albino guinea pigs. RESULTS: PKC alpha immunoreactivities were shown in the outer and inner hair cell cytoplasm and delta was revealed in the type II fibrocytes and suprastrial cells in the basal turn of the spiral ligament. But beta, gamma were not shown. CONCLUSION: We suggest that PKC alpha may induce the slow motility and depolarization to mediate the ion conductance in the hair cells. Also, PKC delta may participate in the production of endolymph. We thus conclude that PKC alpha and delta play an important role in the cochlear signal transduction.

BACKGROUND/AIMS: Previous studies from Korea have described chronic intestinal pseudo-obstruction (CIPO) patients with transition zone (TZ) in the colon. In this study, we evaluated the pathological characteristics and their association with long-term outcomes in Korean colonic pseudo-obstruction (CPO) patients with TZ. METHODS: We enrolled 39 CPO patients who were refractory to medical treatment and underwent colectomy between November 1989 and April 2016 (median age at symptoms onset: 45 [interquartile range, 29–57] years, males 46.2%). The TZ was defined as a colonic segment connecting a proximally dilated and distally non-dilated segment. Detailed pathologic analysis was performed. RESULTS: Among the 39 patients, 37 (94.9%) presented with TZ and 2 (5.1%) showed no definitive TZ. Median ganglion cell density in the TZ adjusted for the colonic circumference was significantly decreased compared to that in proximal dilated and distal non-dilated segments in TZ (+) patients (9.2 vs 254.3 and 150.5, P < 0.001). Among the TZ (+) patients, 6 showed additional pathologic findings including eosinophilic ganglionitis (n = 2), ulcers with combined cytomegalovirus infection (n = 2), diffuse ischemic changes (n = 1), and heterotropic myenteric plexus (n = 1). During follow-up (median, 61 months), 32 (82.1%) TZ (+) patients recovered without symptom recurrence after surgery. The presence of pathological features other than hypoganglionosis was an independent predictor of symptom recurrence after surgery (P = 0.046). CONCLUSIONS: Hypoganglionosis can be identified in the TZ of most Korean CPO patients. Detection of other pathological features in addition to TZ-associated hypoganglionosis was associated with poor post-operative outcomes.

BACKGROUND: This study evaluated the effects of family type and sociodemographic factors on medical treatment, health behavior, and subjective health status in Koreans 60 years and older. METHODS: This study was based on data from the 5th Korea National Health and Nutrition Examination Survey (KNHANES), a nationwide health interview survey using a rolling sampling design involving complex, stratified, multistage, probability cluster. Our subjects included those > or =60 years of age (n=1,946) participating in the KNHANES 2010. Family type was categorized into 7 groups according to cohabitation: alone, couple cohabitation (living with a spouse), parent(s) cohabitation (couple living with parent(s)), offspring cohabitation (no spouse, living with offspring), couple offspring cohabitation (couple living with offspring), couple offspring parents cohabitation (couple living with parent(s) and offspring), and others. Logistic regression analyses were used to examine the association of family type and sociodemographic factors with health care. RESULTS: The most common family type was couple cohabitation (38.26+/-1.8%). In this group, the percentage of non-receipt of needed medical care (odds ratio [OR], 0.60; 95% confidence interval [CI], 0.42 to 0.87) and current smoking rate (OR, 0.32; 95% CI, 0.20 to 0.50) were significantly lower than those living alone. Among the sociodemographic charicteristics, male gender, apartment dwelling, high middle household income, 2 member family, education higher than middle school, and possessing own house were associated with good health care behavior. CONCLUSION: This study shows that couples have better health care behavior than other family types, in particular, limited smoking, appropriate medical treatment, and positive subjective health status. Those living alone visit medical clinics less often and have a negative subjective health status.

Carpal tunnel syndrome, compression of the median nerve in the carpal tunnel at the wrist, is the most common entrapment syndrome of peripheral nerve. It is characterized by sensory and motor symptoms and signs in the distribution of the median nerve. Radiofrequency thermocoagulation is a neuroablative treatment for various chronic pain disorders, but is associated with neural injury, neuritis, and occasional neuroma. Unlike RF, pulsed radiofrequency, the use of the high current intensity and electrical fields, has been proposed for the modulation of the excited nervous system pathway of pain without neuro-destruction and other potential complications. We report a case of bilateral carpal tunnel syndrome that was relieved after PRF lesioning of both median nerves.
