Pancreas divisum—failure of fusion of the dorsal and ventral pancreatic ducts—is relatively well known as the most common congenital anomaly of the pancreatic duct, of with an incidence approximately 10% of all embryos. And there is a rare anomaly similar to pancreas divisum in which doubled ducts are formed. This condition is a rare developmental anomaly called pancreas bifidum or bifid pancreas or fish tail pancreas. This report describes a patient with pancreas bifidum who had 2 separated ducts within the pancreas from tail to neck but did not have a separated parenchyma. We hope that this report helps pancreatic surgeons to have knowledge of pancreas bifidum and helps them to be prepared for this anatomical variant.

PURPOSE: The aim of this study is to elucidate the fundamental characteristics of the laparoscopic splenectomy and to compare the clinical outcomes and postoperative pain between the laparoscopic splenectomy and the conventional open splenectomy. METHODS: From January 2005 to January 2013, 28 patients underwent a splenectomy at Pusan National University Hospital, South Korea (PNUH). This study was a comparison of the demographic features and clinical results between the laparoscopic splenectomy (n=15) and open splenectomy (n=13). RESULTS: For the two groups of patients, the following were similar: estimated blood loss, transfusion, operative time, duration of patient-controlled analgesia, and the additional administration of painkillers. In the laparoscopic splenectomy group, the postoperative hospital stay (7.9+/-1.6 days versus 5.9+/-1.4 days, p=0.002) and the diet start time (2.7+/-0.3 days versus 1.8+/-0.8 days, p=0.003) were significantly shorter. No significant difference in postoperative pain was observed between the two groups. CONCLUSION: In this study, there was no benefit for postoperative pain in the LS group. However, the laparoscopic splenectomy has several benefits, including a shorter postoperative hospital stay and an earlier diet start time; in addition, it is feasible and safe.

The diagnosis of acute ischemic stroke (AIS) can be challenging when neuroimaging findings are normal or equivo‑ cal. Neutrophil extracellular traps (NETs), particularly histone H3.1, have potential as biomarkers for AIS. This study evaluated NETs, specifically histone H3.1, as diagnostic biomarkers for AIS. This prospective study included 89 patients with AIS and 20 healthy controls. Plasma histone H3.1 levels were measured using the Nu.Q® H3.1 enzyme-linked immunosorbent assay (ELISA). Seven cytokines were analyzed using a bead-based immunoassay. Statistical analy‑ ses were used to compare histone H3.1 levels between groups and evaluate correlations with clinical parameters and cytokines. Histone H3.1 levels were significantly higher in patients with AIS (271.05 ± 33.40 ng/mL) versus controls (95.33 ± 12.86 ng/mL, p < 0.001). Multivariable logistic regression identified H3.1 as an independent risk factor for AIS (p = 0.006), with an area under the curve of 0.907. Significant correlations were found between H3.1, interleukin-6 (0.290, p = 0.013) and vascular cell adhesion molecule 1 (0.297, p = 0.011). In conclusion, the NETs H3.1 ELISA test is a reliable new diagnostic option that supports the diagnosis of AIS.

Recently the use of I-PSS (International prostate symptom score) is highly recommended for the evaluation of symptomatic benign prostatic hyperplasia (BPH) and many linguistic translations have been made. Regardless the validity and reliability of linguistic translation, there might be several social and cultural factors which affect to the symptom severity in BPH. We tried to show the prevalence of prostatism and the effect of social and cultural background which could affect to the results I-PSS questionnaire in Korea. A total of 841 men (40~79 years) who visited 4 health care center were included. Because of 107 men had medico-surgical history relating to voiding, final eligible subjects were 734. Total symptom scores increased by age decades (40~49, 50~59, 60~ 69, 70~79; median 7, 8, 11, 12 respectively). The rate of mild (0~7); moderate (8~19); and severe (20~35) symptom in 40th, 50th, 60th and 70th were 55.5%; 39.3%; 1.2%, 45.4%; 46.5%; 8.1%, 30.4%; 53.9%; 15.7% and 28.1%; 43.8%; 28.1% respectively. One cause of these high prevalence of prostatism in Korea is relatively very small proportion of readily treated BPH patients in general population (0.5%). Another factor of the high prevalence of prostatism is thought to be the different social and cultural concept to voiding status. These factors limit comparability of I-PSS questionnaire between different countries.

Mesenchymal stem cells (MSCs) are capable of self-renewal and differentiation into lineages of mesenchymal tissues that are currently under investigation for a variety of therapeutic applications. The purpose of this study was to compare cytokine gene expression in MSCs from human placenta, cord blood (CB) and bone marrow (BM). The cytokine expression profiles of MSCs from BM, CB and placenta (amnion, decidua) were compared by proteome profiler array analysis. The cytokines that were expressed differently, in each type of MSC, were analyzed by real-time PCR. We evaluated 36 cytokines. Most types of MSCs had a common expression pattern including MIF (GIF, DER6), IL-8 (CXCL8), Serpin E1 (PAI-1), GROalpha(CXCL1), and IL-6. MCP-1, however, was expressed in both the MSCs from the BM and the amnion. sICAM-1 was expressed in both the amnion and decidua MSCs. SDF-1 was expressed only in the BM MSCs. Real-time PCR demonstrated the expression of the cytokines in each of the MSCs. The MSCs from bone marrow, placenta (amnion and decidua) and cord blood expressed the cytokines differently. These results suggest that cytokine induction and signal transduction are different in MSCs from different tissues.

OBJECTIVE: Hypermethylation of p16, a tumor suppressor gene, has been frequently detected in a variety of cancer cells and is known to represent the level of p16 transcription. In human meningiomas, genetic alterations of p16 have shown to be infrequent. The purpose of this study is to investigate the role of p16 associated with the progression of meningiomas. METHODS: Sixty-eight meningiomas(randomly sampled 29 benign, 16 atypical and 23 malignant formalin-fixed, paraffin-embedded tissues) were analyzed. We examined the molecular mechanism of inactivation of p16 in these benign, atypical and malignant meningiomas by detecting the methylation status of p16 using methylation-specific polymerase chain reaction. RESULTS: One out of 29(3.4%) revealed hypermethylation of p16 in benign meningiomas. Atypical and malignant meningiomas showed hypermethylation of p16 in 2 out of 16 cases(12.5%) and in 5 out of 23 cases(21.7%), respectively. Immunohistochemical analysis of methylation-positive tumors demonstrated that tumor cells had reduced immunoreactivity compared to normal lymphocytes. CONCLUSIONS: Our results suggest that inactivation of p16 gene plays a role in the pathogenesis of meningioma and hypermethylation is one of the processes for gene inactivation.
