Purpose: Resectable pancreatic ductal adenocarcinoma (PDAC) has a high risk of recurrence after curative resection; despite this, the preoperative risk factors for predicting early recurrence remain unclear. This study therefore aimed to identify preoperative inflammation and nutrition factors associated with early recurrence of resectable PDAC. Methods: From March 2021 to November 2021, a total of 20 patients who underwent curative resection for PDAC were enrolled in this study. We evaluated the risk factors for early recurrence within 1 year by univariate and multivariate analyses using Cox hazard proportional regression. The cutoff values for predicting recurrence were examined using receiver operating characteristic (ROC) curves. Results: In our univariate and multivariate analyses, C-reactive protein (CRP), CRP-albumin ratio, and CRP-prealbumin ratio, as well as sex and age, were significant independent prognostic factors for early recurrence in PDAC. However, known inflammatory factors (neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios), nutritional factors (albumin, prealbumin, ferritin, vitamin D), and inflammatory-nutritional factors (Glasgow Prognostic Score, modified Glasgow Prognostic Score, albumin-bilirubin) showed no association with early recurrence. In addition, using cutoff values by ROC curve analysis, a high preoperative CRP level of >5 mg/L, as well as high CRP-to-albumin (>5.3) and CRP-to-prealbumin (>1.3) ratios showed no prognostic value. Conclusion Our results showed that inflammatory and perioperative nutritional factors, especially CRP-to-prealbumin ratio, have significant associations with early recurrence after curative resection in resectable PDAC. Therefore, for such patients, a cautious approach is needed when inflammation and poor nutritional status are present.

Purpose: Although there are many studies on prealbumin in individual diseases such as malignant or inflammatory diseases, there are few comparative studies. This study aimed to compare the clinical differences between prealbumin levels in cholecystitis and pancreaticobiliary malignancies and investigate the clinical impact of low prealbumin levels in pancreaticobiliary malignancies. Methods: From June 2021 to September 2021, 61 patients who had undergone surgery for various pancreaticobiliary diseases were enrolled in this study, and their clinicopathological data were retrospectively analyzed. Results: Many elderly patients with malignant diseases had poor American Society of Anesthesiologists (ASA) scores, significantly lower albumin and prealbumin levels, and higher systemic immune inflammation indices. The low prealbumin group was older; had poorer ASA scores; and had significantly lower body mass index and hemoglobin and albumin levels and higher systemic immune inflammation indices than the normal prealbumin group. In malignant diseases, the low prealbumin group had significantly lower body mass index and hemoglobin levels and a tendency toward more advanced disease (lymph node and distant metastasis). Conclusion Preoperative low prealbumin levels had an area under the receiver operator characteristic curve of 0.69, suggesting that it may be useful for predicting pancreaticobiliary malignancies. Prealbumin levels were lower in malignant diseases, possibly related to poor nutritional status and systemic immune inflammation. Low prealbumin levels may predict the risk of more advanced disease.

PURPOSE: The aim of the present study is to assess the importance of proper treatment timing for dental emergency patients by characterizing current patient care in the emergency room. MATERIALS AND METHODS: A retrospective chart review of 3,211 patients who visited the Chosun University Hospital's dental emergency department (Gwangju, Korea) was conducted from January 1, 2011 to May 31, 2014. Information regarding age, gender, onset date, main causes, and diagnoses were collected and analyzed. The main causes were divided into six categories: assault, household/play, sports, traffic, work, and others. RESULT: Emergency visits were more common for men (69%), and the ratio of males to females was 2.2:1 On average, the major cause was household/play (49.8%), followed by others (18.9%), traffic (16.6%), assault (9.1%), sports (2.9%), and work (2.6%). The most frequent diagnosis on average was dental trauma with 82.4%, followed by infection (10.7%), others (4.7%), and bleeding (2.2%). CONCLUSION: The main reasons for visits to the dental emergency department are dental trauma, dental infection, bleeding, and others. The most frequent reason for dental emergency patients to visit the emergency department was dental trauma (82.4%).

BACKGROUND/AIMS: Quantification of hepatitis B surface antigen (HBsAg) is an emerging serologic test and may be useful for identifying treatment strategies for chronic hepatitis B (CHB). This study aimed to evaluate HBsAg titers during the natural course of CHB and identify correlations between HBsAg titers and hepatitis B virus (HBV) DNA concentrations across different CHB phases measured using an immunoradiometric assay (IRMA). METHODS: CHB phases were defined on the basis of HBV DNA concentrations, the presence of hepatitis B e antigen/antibody (HBeAg/Ab) and serum alanine aminotransferase levels. Serum HBsAg titers and paired HBV DNA concentrations in the different phases of CHB were compared using 627 serum samples. RESULTS: Mean HBsAg titers were significantly higher in the immunotolerant (IT) phase and immunoreactive (IR) HBeAg-positive phase than in the low-replicative (LR) and HBeAg-negative CHB (ENH) states. The correlation between HBsAg titers and HBV DNA concentrations was modest in the IT (n=36, r=0.804, p<0.001) and IR (n=48, r=0.773, p<0.001) phases, and it was poor in the LR state (n=116, r=0.289, p=0.002); however, no significant correlation was observed in the ENH state (n=67, r=0.146, p=0.237) or in the oral nucleos(t)ide analogue-treated group (n=267). CONCLUSIONS: HBsAg quantification using IRMA might be useful for discriminating different CHB phases and different stages of chronic liver disease.

BACKGROUND AND PURPOSE: Neuropsychological and neuroimaging studies both suggest that frontal lobe dysfunction is present in migraineurs. Since P3a abnormalities manifest in other diseases associated with attention problems, such as attention deficit hyperactivity disorder, we hypothesized that migraine patients have P3a abnormalities, particularly in the frontal region. METHODS: Event-related potentials were measured using a passive auditory oddball paradigm in 16 female migraineurs (aged 22.9+/-2.0 years, mean+/-SD) during the interictal period and in 16 age-matched healthy females (22.6+/-2.0 years). The amplitudes and latencies were analyzed independently using repeated-measures analysis of variance. Nonparametric statistical testing using a cluster-level randomization method was performed to localize the abnormalities. RESULTS: The mean P3a amplitude at frontal areas during the third trials was significantly lower in migraineurs (1.06 microV) than in controls (1.69 microV, p=0.026). P3a amplitudes were negatively correlated with the duration of the migraine history (r=-0.618, p=0.014). Cluster-based nonparametric statistical analysis showed that the amplitudes over left frontal areas were significantly lower in migraine patients than in controls. CONCLUSIONS: A reduced P3a amplitude of migraineurs reflects attentional deficits and frontal dysfunction. The negative correlation between P3a amplitude and the duration of the migraine history suggests that attentional deficits and frontal dysfunction are either the cause or the result of headache.

BACKGROUND: Plasma specimens are recently used instead of serum in clinical chemistry to improve (test result turnaround time, TAT). We evaluated the performance of lithium heparin gel plasma separating tube in comparison to existing vacutainer gel serum tube in common clinical chemistry assays. METHODS: Total 52 subjects who had visited the health promotion center were included in the study. Lithium heparin plasma tubes and serum tubes were tested for 30 clinical chemistry items and 3 cardiac markers. Test results were analyzed by calculation of mean bias and percent difference. RESULTS: The performance of the lithium heparin plasma tube was considered to be clinically equivalent to the serum tube for all assays except for potassium. The difference of potassium levels between lithium heparin plasma tube and the serum tube was -7.32%. Test results of some analytes including glucose, lactate dehydrogenase, total CO2 and potassium using the lithium heparin tube were significantly changed after 24 hours of storage. CONCLUSIONS: The lithium heparin plasma tube provided acceptable results comparison to the existing serum separating tube in common clinical chemistries and can be used for reducing, TAT. However, the stability of plasma gel tubes on 24 hours of storage was unstable in some analytes, it requires attention.

Rapidly progressive glomerulonephritis (RPGN) in Wegener's granulomatosis patients typically has been characterized by pauci-immune glomerulonephritis (PIGN). In some patients, however, significant amount of glomerular immune deposits was detected and reported that they may have poor prognosis. A 30 year-old-female visited due to the skin rash of both lower extremities, arthralgia and nasal stiffness. She had sinusitis, lung opacity, and proteinuria. Serologic PR-3 ANCA was positive and histologic findings of nasal cavity and lung also showed necrotizing vasculitis and granuloma. Thus we could diagnose Wegener's granulomatosis. However, gross hematuria developed and renal function worsened in spite of treatment with high dose prednisolone and oral cyclophosphamide. Therefore we performed a kidney biopsy. The kidney biopsy showed crescentic glomerulonephritis with Ig A deposition in the mesangium. We experienced a case of Wegener's granulomatosis patient with significant IgA deposition in glomeruli. We report this case with brief review of the literature.
