Erythema nodosum is considered to be a hypersensitivity reaction to various conditions. Vaccination-related erythema nodosum is uncommon but cases associated with hepatitis B virus, human papillomavirus, tetanus, diphtheria and pertussis, rabies, smallpox, typhoid and cholera, and Bacille-Calmette-Guerin vaccinations have beenreported. A 33-year-old Korean woman presented with a 3-day history of painful erythematous plaques on both lower legs and knees. Prior to the development of the skin rash, she had received the pneumococcal polysaccharide conjugate vaccine Prevenar13(R). Histological examination of the left lower leg lesion revealed septal panniculitis without vasculitis. To the best of our knowledge, erythema nodosum caused by pneumococcal vaccination has not previously been reported. It is important for clinicians to be aware of this rare, yet potential, adverse effect to the pneumococcal vaccine.

It is well known that malnutrition is a predictor of mortality in hemodialysis patients. The number of diabetic nephropathy patients is increasing rapidly. This study aimed to investigate nutritional status and nutrient intake according to the presence of diabetes among hemodialysis patients. The nutritional intake and general characteristics of outpatients at Ajou University Hospital (24 with diabetes and 30 without diabetes) were investigated between July and September 2015. Patients' general data were collected, and nutritional status by Patient-Generated Subjective Global Assessment (PG-SGA) was evaluated. Nutrient intakes were assessed according to 3-day food records. There was no significant difference regarding body weight between the two groups. However, the non-diabetic group showed a better nutritional status by Patient-Generated Subjective Global Assessment (PG-SGA) (5.2±4.4 vs. 8.0±4.3 score, non-diabetics vs. diabetics, P<0.05). There was no difference in daily calorie intake (1,473.9±370.5 vs. 1,503.8±397.5 kcal) and protein intake (60.3±19.7 vs. 65.6±20.5 g) in those with diabetes. Intakes of vegetables protein, sodium, potassium, vitamin C, folic acid and fiber were significantly higher in the diabetic group compared to those of the non-diabetic group. There was no difference in daily nutrient intake between the hemodialysis weekday and weekend groups. The non-diabetic group had higher calorie and sodium intakes per meal in the hemodialysis weekday group, but the difference was not significant. Based on these results, intervention should be performed to improve nutritional status in consideration of diabetes and dietary patterns.

Acrodermatitis enteropathica is classified as a congenital autosomal recessive type and an acquired transient type. This disease manifests as acral and periorificial dermatitis, alopecia, intractable diarrhea, and failure to thrive. Whereas the autosomal hereditary type is caused by malabsorption of zinc in the intestine, the acquired type is caused by low nutritional support or decreased peripheral release of zinc from blood. We experienced a case of a 5-month old, breast feeding, full-term female presenting with only acral bullous dermatitis without diarrhea, periorificial dermatitis and an abnormal serum zinc level.

BACKGROUND: Monitoring the "depth of anesthesia" is an ongoing problem. To identify a useful parameter for determining the depth of anesthesia with enflurane, EEG data was obtained using a Physiolab 800. METHODS: Variations in EEG signals were measured and analyzed by the stage of anesthesia. EEG data was obtained from 15 patients during general anesthesia with enflurane. The EEG signal was acquired and analyzed in 5 steps (one day before anesthesia, during induction, during skin incision, at end of anesthesia, and one day after anesthesia). Fp1 electrode and the EEG data mainly from the forehead were used to determine the depth of anesthesia using EEG characteristics during enflurane anesthesia. All data were preprocessed by filtering, baseline correction and using the linear detrend method to reliable analyze of sample data in the surgical environment. Data obtained were transformed to frequency and power spectrum analysis was performed. RESULTS: alpha, beta, delta and theta waves were detected by frequency area separation and the trend of each wave was observed during each anesthesia stage. EEG data was slowed down and the theta wave ratio increased as the depth of anesthesia increased. Accordingly, spectral edge frequency (SEF) and median frequency (MF) were used as parameters to determine the depth of anesthesia. The frequencies of SEF and MF decreased during anesthesia and returned to the preanesthetic level after the cessation of anesthesia. CONCLUSIONS: Our results suggest that SEF and MF can contribute as useful parameters to determine the depth of anesthesia. Anesthetics not only affect the central nervous system, but also affect the autonomic nervous system. If the autonomic nervous system signals such as heart rate variability are taken into account, more reliable evaluations would be possible.

Determining blood loss [100% – RBV (%)] is challenging in the management of haemorrhagic shock. We derived an equation estimating RBV (%) via serial haematocrits (Hct1 , Hct2 ) by fixing infused crystalloid fluid volume (N) as [0.015 × body weight (g)]. Then, we validated it in vivo. Mathematically, the following estimation equation was derived: RBV (%) = 24k / [(Hct1 / Hct2 ) – 1]. For validation, nonongoing haemorrhagic shock was induced in Sprague–Dawley rats by withdrawing 20.0%–60.0% of their total blood volume (TBV) in 5.0% intervals (n = 9). Hct1 was checked after 10 min and normal saline N cc was infused over 10 min. Hct 2 was checked five minutes later. We applied a linear equation to explain RBV (%) with 1 / [(Hct1 / Hct2 ) – 1]. Seven rats losing 30.0%–60.0% of their TBV suffered shock persistently. For them, RBV (%) was updated as 5.67 / [(Hct1 / Hct2 ) – 1] + 32.8 (95% confidence interval [CI] of the slope: 3.14–8.21, p = 0.002, R2 = 0.87). On a Bland-Altman plot, the difference between the estimated and actual RBV was 0.00 ± 4.03%; the 95% CIs of the limits of agreements were included within the pre-determined criterion of validation (< 20%). For rats suffering from persistent, non-ongoing haemorrhagic shock, we derived and validated a simple equation estimating RBV (%). This enables the calculation of blood loss via information on serial haematocrits under a fixed N.Clinical validation is required before utilisation for emergency care of haemorrhagic shock.

BACKGROUND: We performed the study on the changes of beta2-microglobulin(beta2M) clearance and urea reduction ratio after reuse of dialyzers with three different membranes. METHODS: 9 patients who had received regular hemodialysis more than five years were enrolled. Three kinds of dialyzer membrane were used; i.e. : Two of them were high-flux and the other was low-flux. Dialyzer reprocessing was performed by an automated machine using glutaraldehyde and bleach. Each dialyzer was reused 10 times. Solute clearance was determined for each dialyzer after the 1st, 5th, 8th and 10th reuse. RESULTS: Urea clearance was well maintained after reuse with both high-flux and low-flux membrane but beta2M clearance was significantly greater with high-flux dialyzers than low-flux dialyzer. Effects of each dialyzer reuse on beta2M clearance showed no significant decrease until the 10th reuse and no significant difference in beta2M clearance between the two high-flux dialyzers(polyamide vs PEPA membrane, p= 0.197). CONCLUSION: Reuse of dialyzers was cost-effective. After reuse of dialyzer, clearance of solute was maintained in both small and large solutes until the 10 th reuse. Further study is needed regarding the maintenance of solute clearance with increased number of reuses.

Apoptosis is an important host defense mechanism against mycobacterial infection. Recent reports suggest that links between apoptosis and endoplasmic reticulum (ER) stress are critical for the regulation of mycobacterial survival; however, the exact regulatory mechanisms are not well known. In this study, we isolated 20 Mycobacterium tuberculosis (Mtb) clinical strains from Korean patients and examined ER stress-mediated apoptosis in Mtb-infected macrophages. Most Mtb strains increased the rates of apoptosis and production of ER stress-sensing molecules in mouse macrophages, similar to Mtb H37Rv infection. Moreover, the intracellular survival of Mtb clinical isolates in macrophages was similar to that of H37Rv. Our data suggest that infection with Mtb downregulated MCP-1 and MCPIP. The regulation of MCPIP may decrease ROS production, leading to a reduction in ER stress-mediated apoptosis.

PURPOSE: We evaluated the utility of magnetic resonance imaging (MRI) and 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for the preoperative staging of invasive lobular carcinoma (ILC) of the breast and compared the results with those of invasive ductal carcinoma (IDC). METHODS: The study included pathologically proven 32 ILCs and 73 IDCs. We compared clinical and histopathological characteristics and the diagnostic performances of MRI and 18F-FDG PET/CT for the primary mass, additional ipsilateral and/or contralateral lesion(s), and axillary lymph node metastasis between the ILC and IDC groups. RESULTS: Primary ILCs were greater in size, but demonstrated lower maximum standardized uptake values than IDCs. All primary masses were detected on MRI. The detection rate for ILCs (75.0%) was lower than that for IDCs (83.6%) on 18F-FDG PET/CT, but the difference was not significant. For additional ipsilateral lesion(s), the sensitivities and specificities of MRI were 87.5% and 58.3% for ILC and 100.0% and 66.7% for IDC, respectively; whereas the sensitivities and specificities of 18F-FDG PET/CT were 0% and 91.7% for ILC and 37.5% and 94.7% for IDC, respectively. The sensitivity of 18F-FDG PET/CT for ipsilateral lesion(s) was significantly lower in the ILC group than the IDC group. The sensitivity for ipsilateral lesion(s) was significantly higher with MRI; however, specificity was higher with 18F-FDG PET/CT in both tumor groups. There was no significant difference in the diagnostic performance for additional contralateral lesion(s) or axillary lymph node metastasis on MRI or 18F-FDG PET/CT for ILC versus IDC. CONCLUSION: The MRI and 18F-FDG PET/CT detection rates for the primary cancer do not differ between the ILC and IDC groups. Although 18F-FDG PET/CT demonstrates lower sensitivity for primary and additional ipsilateral lesions, it shows higher specificity for additional ipsilateral lesions, and could play a complementary role in the staging of ILC as well as IDC.

PURPOSE: We validated the performance of the San Francisco Syncope Rule (SFSR) for accurate identification of Korean emergency department (ED) syncope patients who will experience a short term serious outcome. METHODS: This retrospective study included patients over 16 years old who fulfilled the inclusion criteria according to the definition of syncope and visited the ED from January 2010 to June 2013. The authors excluded patients with alcohol or illicit drugs use seizure, stroke or transient ischemic attack, head trauma followed by loss of consciousness, or hypoglycemia. The patients were divided into two groups according to the SFSR for the purpose of performing a comparative analysis. The authors calculated sensitivity, specificity, positive predictive value, and negative predictive value of SFSR and analyzed other variables, except five predictor variables of SFSR. RESULTS: Of 1,235 visits screened, 409 were included. The average age of enrolled patients was 55.2+/-20.1 and male population accounted for 45.0%(n=184). A total of 93(27.7%) patients experienced serious outcomes; 41 of 287(14.3%) patients with a serious outcome were not identified as high risk according to the rule. The rule performed with a sensitivity of 55.9%, specificity of 77.8%, positive predictive value of 42.6%, and negative predictive value of 85.7%. CONCLUSION: In this retrospective validation study based on the standardized reporting guidelines for ED syncope risk stratification research, the SFSR performed with significantly lower sensitivity than previously reported. The results suggest that application of the original rule has limited generalizability and conduct of future studies will be needed in order to refine the SFSR.
