Verumontanum mucosal gland hyperplasia (VMGH) is a relatively common benign proliferative lesion which was first described by Gagucas et al in 1995. VMGH is usually found in radical prostatectomy or transurethral resection specimens and rarely in needle biopsy specimens. The histologic feature of VMGH is characterized by well-circumscribed proliferation of small glands and thus VMGH may mimic low grade adenocarcinoma. We report a case of VMGH from a 61-year-old man. The lesion coexisted with prostatic adenocarcinoma on radical prostatectomy specimen. The lesion was a well circumscribed microacinar proliferation which was present between the openings of ejaculatory ducts. The acini consisted of two cell layers with inner secretory cuboidal epithelium and outer basal cell. Typically, the lumen contained many corpora amylacea. Nuclear pleomorphism, prominent nucleolus, or mitotic figure was not identified. Because of small gland proliferation of VMGH, this lesion can be confused with other small gland proliferative lesions, such as low grade adenocarcinoma, atypical adenomatous hyperplasia, basal cell hyperplasia, mesonephric hyperplasia, and nephrogenic adenoma. To avoid misdiagnosis of VMGH as carcinoma, one should be familiar with this lesion.

We report here on a case of combined hepatocellular and cholangiocarcinoma (CHC) with neuroendocrine differentiation and sarcomatoid transformation. A 59-year-old male who had had HBV-associated chronic liver disease presented with hepatic masses. The explanted liver showed three small masses, two in the right lobe and one in the left lobe. The largest one in the right lobe was a 2.0 cm sized binodular mass,consisting of a yellowish tan nodule and an abutting reddish brown nodule. Microscopically, the reddish brown nodule was a cholangiocarcinoma (CC) showing neuroendocrine differentiation and sarcomatoid tranformation. The yellowish tan nodule and the remaining two masses were hepatocellular carcinoma (HCC)s. On immunohistochemistry, both the adenocarcinoma and spindle sarcomatoid cells were positive for pancytokeratin, but only the adenocarcinoma cells were positive for chromogranin and carcinoembryonic antigen (CEA). Mitotic and Ki67 labeling indices as well as p53 immunopositivity were significantly increased only in the CC component. We report here on the first case of CHC in which the CC displayed neuroendocrine differentiation and sarcomatoid transformation with high mitotic and Ki67-labeling indices, as well as having p53 overexpression.

OBJECTIVE: This study evaluated whether emergency medical service (EMS) use was associated with early arrival and admission for definitive care among intracerebral hemorrhage (ICH) patients. METHODS: Patients with ICH were enrolled from 29 hospitals between November 2007 and December 2012, excluding those patients with subarachnoid hemorrhage, traumatic ICH, and missing information. The patients were divided into four groups based on visit type to the definitive hospital emergency department (ED): direct visit by EMS (EMS-direct), direct visit without EMS (non-EMS-direct), transferred from a primary hospital by EMS (EMS-transfer), and transferred from a primary hospital without EMS (non-EMS-transfer). The outcomes were the proportions of participants within early (<1 hr) definitive hospital ED arrival from symptom onset (pS2ED) and those within early (<4 hr) admission from symptom onset (pS2AD). Adjusted odds ratios were calculated to determine the association between EMS use and outcomes with and without inter-hospital transfer. RESULTS: A total of 6,564 patients were enrolled. The adjusted odds ratios (95% confidence intervals) for pS2ED were 22.95 (17.73–29.72), 1.11 (0.67–1.84), and 7.95 (6.04–10.46) and those for pS2AD were 5.56 (4.70–6.56), 0.96 (0.71–1.30), and 2.35 (1.94–2.84) for the EMS-direct, EMS-transfer, and non-EMS-direct groups compared with the non-EMS-transfer group, respectively. Through the interaction model, EMS use was significantly associated with early arrival and admission among direct visiting patients but not with transferred patients. CONCLUSION: EMS use was significantly associated with shorter time intervals from symptom onset to arrival and admission at a definitive care hospital. However, the effect disappeared when patients were transferred from a primary hospital.

BACKGROUND/OBJECTIVES: Acanthopanax sessiliflorus is a native Korean plant and used as traditional medicine or an ingredient in many Korean foods. The free radical theory of aging suggests that cellular oxidative stress caused by free radicals is the main cause of aging. Free radicals can be removed by cellular anti-oxidants. MATERIALS/METHODS: Here, we examined the anti-oxidant activity of Acanthopanax sessiliflorus extract both in vitro and in vivo. Survival of nematode C. elegans under stress conditions was also compared between control and Acanthopanax sessiliflorus extract-treated groups. Then, anti-aging effect of Acanthopanax sessiliflorus extract was monitored in C. elegans. RESULTS: Stem extract significantly reduced oxidative DNA damage in lymphocyte, which was not observed by leaves or root extract. Survival of C. elegans under oxidative-stress conditions was significantly enhanced by Acanthopanax sessiliflorus stem extract. In addition, Acanthopanax sessiliflorus stem increased resistance to other environmental stresses, including heat shock and ultraviolet irradiation. Treatment with Acanthopanax sessiliflorus stem extract significantly extended both mean and maximum lifespan in C. elegans. However, fertility was not affected by Acanthopanax sessiliflorus stem. CONCLUSION: Different parts of Acanthopanax sessiliflorus have different bioactivities and stem extract have strong anti-oxidant activity in both rat lymphocytes and C. elegans, and conferred a longevity phenotype without reduced reproduction in C. elegans, which provides conclusive evidence to support the free radical theory of aging.

BACKGROUND/OBJECTIVES: Cholecystokinin (CCK), a hormone or neuropeptide, is secreted in response to intraluminal nutrients by enteroendocrine I-cells of the intestine and has important physiological actions related to appetite regulation and satiety. The stimulation on CCK secretion from the intestine is of potential relevance for body weight management. Naringenin (4',5,7-trihydroxyflavanone) and its glycoside naringin (naringenin 7-rhamnoglucoside) have been reported to have many biological functions. In the current study, we investigated the question of whether naringenin and naringin could stimulate CCK secretion and then examined the mechanisms involved in CCK release. MATERIALS/METHODS: STC-1 cells were used as a model of enteroendocrine cells. CCK release and changes in intracellular Ca2+ ([Ca2+]i) were measured after incubation of cells with naringenin and naringin for 1 h. RESULTS: Naringenin caused significant (P < 0.05) stimulation of CCK secretion, but naringin did not. In addition, regarding the secretory mechanisms, naringenin-induced CCK secretion involved increases in [Ca2+]i, influx of extracellular Ca2+, at least in part, and activation of TRP channels, including TRPA1. CONCLUSION: Findings of this study suggest that naringenin could have a role in appetite regulation and satiety.

Primary duodenal carcinoma is rare. Duodenal mucinous adenocarcinoma (DMA) is even rarer, and its associated manifestations and typical endoscopic or imaging findings are not well characterized. Herein, we report a case of primary DMA in an asymptomatic 58-year-old man who visited our hospital for a regular health screening. Upper endoscopy revealed an approximately 4-cm lesion in the second portion of the duodenum, but the mass was not visualized on computed tomography. Biopsies revealed a tubular adenoma that was subsequently resected. Frozen biopsies demonstrated DMA with a background of low-grade tubular adenoma for which we performed Roux-en-Y duodenojejunostomy and jejunojejunostomy. To our knowledge, this is the first report of a patient with DMA in Korea.

Leiomyoma arising primarily in the ovary is a rare tumor, accounting for only 1% of benign ovarian neoplasms. About 50 cases have been reported in the literature to date. Most cases are asymptomatic and this benign neoplasm is usually found incidentally on routine pelvic examination, at surgery, or at autopsy. We present a case of ovarian leiomyoma in 39-year-old woman which has been experienced in our hospital with brief review of literature.

Background:
Recently, a study comprising adult patients with sepsis admitted in the intensive care unit (ICU) was conducted. The patients were treated with high doses of intravenous ascorbic acid, thiamine, and hydrocortisone; the clinical outcomes demonstrated significant therapeutic benefits. The mortality rate in children with sepsis is approximately 25%. However, the effects of additional treatment with ascorbic acid and thiamine (“vitamin protocol”) in children are rarely investigated.
Methods:
A retrospective analysis was performed using medical records of patients diagnosed with sepsis and admitted to the pediatric ICU (PICU) between September 2016 and June 2019. The control group received treatment only as per sepsis protocol, whereas the treated group received both sepsis protocol and the vitamin protocol. The primary endpoint was change in Vasoactive-Inotropic Score (VIS) for 5 days. The secondary endpoints included the length of stay in the PICU, duration of using mechanical ventilators and vasopressors, and mortality rate.
Results:
The number of patients in the treated and control groups was 33 and 24, respectively. The treated group showed greater decrease in their VIS for 5 days than the control group (44.4 vs 18.6); however, the difference was not statistically significant. The length of stay in the PICU was significantly longer for the treated group than for the control group [10.0 days (Interquartile range (IQR), 6-18) vs 4.5 days (IQR, 4-10.3); p=0.004].
Conclusions
No significant treatment benefits were observed following vitamin protocol administration to the pediatric patients with sepsis. Further studies are necessary for improving the efficacy and safety of the vitamin protocol.

Background:
Basiliximab is used as an alternative to tacrolimus in patients with decreased renal function. However, studies on basiliximab as a maintenance immunosuppressant, particularly in patients with lung transplantation, are limited. Therefore, here, we investigated the efficacy and safety of basiliximab in patients with lung transplantation.
Methods:
Adult patients with acute kidney injury (AKI) who received lung transplantation at a single general hospital between July 1, 2014 and June 30, 2018, were selected and classified in tacrolimus and basiliximab groups. Both groups received a triple-drug regimen (tacrolimus, mycophenolate mofetil, and steroids). However, tacrolimus was discontinued in the basiliximab group when AKI occurred, and two or more repeat basiliximab doses were administered within 3 months after transplantation. The electronic medical records were analyzed retrospectively.
Results:
Of the 85 patients who met the selection criteria, 61 and 24 were assigned to the tacrolimus and basiliximab groups, respectively. Significant improvement in renal function was observed in the basiliximab group (p <0.001).However, there were no differences in acute and chronic rejection rates in both the groups. No difference was observed in the incidence rate of complications between the groups, except for chronic kidney disease, which showed higher incidence in the basiliximab group (25.0% vs. 4.9%; p =0.013).
Conclusions
We suggest the use of basiliximab as an immunosuppressant alternative to tacrolimus in patients with acute renal failure after lung transplantation. Basiliximab demonstrated effectiveness as an immunosuppressant and improved renal function. Therefore, basiliximab can be used in patients with decreased renal function.
