In Korea, several outbreaks of low pathogenic AI (H9N2) viral infections leading to decreased egg production and increased mortality have been reported on commercial farms since 1996, resulting in severe economic losses. To control the H9N2 LPAI endemic, the Korea Veterinary Authority has permitted the use of the inactivated H9N2 LPAI vaccine since 2007. In this study, we developed a killed vaccine using a low pathogenic H9N2 AI virus (A/chicken/Korea/ADL0401) and conducted safety and efficacy tests in commercial layer farms while focusing on analysis of factors that cause losses to farms, including egg production rate, egg abnormality, and feed efficiency. The egg production rate of the control group declined dramatically 5 days after the challenge. There were no changes in feed consumption of all three groups before the challenge, but rates of the control declined afterward. Clinical signs in the vaccinated groups were similar, and a slight decline in feed consumption was observed after challenge; however, this returned to normal more rapidly than the control group and commercial layers. Overall, the results of this study indicate that the safety and efficacy of the vaccine are adequate to provide protection against the AI field infection (H9N2) epidemic in Korea.

PURPOSE: The aim of this study was to analyze the efficacy and to estimate the complication rate of incontinence surgery according to the surgeon's specialty and whether a preoperative urodynamic study (UDS) was performed, using a nationally representative dataset. METHODS: We enrolled 356,155 women over 20 years old who had undergone surgery for stress urinary incontinence between 2006 and 2015. Patients were followed for up to 3 years to analyze the reoperation and complication rates. Data were obtained from the National Health Claims Database of the National Health Insurance Service (NHIS) of Korea. Multiple Cox regression analysis was conducted to examine the efficacy and safety of incontinence surgery according to the surgeon’s specialty and whether a preoperative UDS was performed. RESULTS: The hazard ratio (HR) for reoperation was significantly higher for procedures performed by nonurologists than for procedures performed by urologists (HR, 1.174; 95% confidence interval [CI], 1.103–1.249). Acute urinary retention, postoperative infections, procedure-associated pain, and other complications were also more common in procedures performed by nonurologists than in those performed by urologists. When stratified by whether a preoperative UDS was performed, the HR for reoperation according to the surgeon’s specialty varied by performance of a preoperative UDS. While the reoperation rate was significantly higher in procedures performed by non-urologists when a preoperative UDS was performed (HR, 1.208; 95% CI, 1.122–1.3), there was no significant difference in the HRs for reoperation according to specialty when a preoperative UDS was not performed. CONCLUSIONS: This population-based study showed that the postoperative outcomes of incontinence surgery were dependent upon the surgeon’s specialty and that the reoperation rate according to the surgeon’s specialty varied based on whether a preoperative UDS was performed.

BACKGROUND: Nefopam has been known as an inhibitor of the reuptake of monoamines, and the noradrenergic and/or serotonergic system has been focused on as a mechanism of its analgesic action. Here we investigated the role of the spinal dopaminergic neurotransmission in the antinociceptive effect of nefopam administered intravenously or intrathecally. METHODS: The effects of intravenously and intrathecally administered nefopam were examined using the rat formalin test. Then we performed a microdialysis study to confirm the change of extracellular dopamine concentration in the spinal dorsal horn by nefopam. To determine whether the changes of dopamine level are associated with the nefopam analgesia, its mechanism was investigated pharmacologically via pretreatment with sulpiride, a dopaminergic D2 receptor antagonist. RESULTS: When nefopam was administered intravenously the flinching responses in phase I of the formalin test were decreased, but not those in phase II of the formalin test were decreased. Intrathecally injected nefopam reduced the flinching responses in both phases of the formalin test in a dose dependent manner. Microdialysis study revealed a significant increase of the level of dopamine in the spinal cord by intrathecally administered nefopam (about 3.8 fold the baseline value) but not by that administered intravenously. The analgesic effects of intrathecally injected nefopam were not affected by pretreatment with sulpiride, and neither were those of the intravenous nefopam. CONCLUSIONS: Both the intravenously and intrathecally administered nefopam effectively relieved inflammatory pain in rats. Nefopam may act as an inhibitor of dopamine reuptake when delivered into the spinal cord. However, the analgesic mechanism of nefopam may not involve the dopaminergic transmission at the spinal level.

BACKGROUND/AIMS: Gastric hepatoid adenocarcinoma (GHA), a rare type of primary gastric cancer, is characterized by a histology resembling hepatocellular carcinoma. Previous case studies reported that patients with GHA have a poor prognosis due to early lymph node or liver metastasis, but information concerning GHA is still limited. Therefore, we aimed to evaluate the clinicopathological features of GHA. MATERIALS AND METHODS: We reviewed the medical records of 9 patients who were diagnosed as having GHA between January 2011 and December 2016. The clinicopathological characteristics of these patients were retrospectively analyzed. RESULTS: The median age of the patients at diagnosis was 68.9 years. Seven of the 9 patients were male. Serum AFP levels were elevated in 3 of 4 patients. All the tumors were >4 cm (range, 4~12 cm), and 7 tumors were located at the lower third of the stomach. Five tumors were classified as Borrmann's type 3, with a purple, berry-like surface. Of the 6 patients without distant metastasis, 5 received curative-intent surgery and 3 received adjuvant chemotherapy. Three patients with distant metastasis received either palliative operation and/or chemotherapy. Their median survival time was 11.8 months (range, 1~36 months). Two patients with elevated serum CEA levels had poor outcomes. CONCLUSIONS: GHA is a rare subtype of gastric cancer that is prone to liver metastasis. All GHAs are advanced gastric cancer with a purple, berry-like surface at diagnosis. Although the prognosis of advanced-stage GHA is poor, active multimodality treatment might provide some benefit.

BACKGROUND/AIMS: Endoscopic resection (ER) is a well-established treatment modality for gastric epithelial neoplasm. However, there is a discrepancy between forceps biopsy and ER specimen pathology, including a negative pathologic diagnosis (NPD) after ER. It has been suggested that pit dysplasia (PD) is a subtype of gastric dysplasia, and the aim of this study was to assess the significance of PD in cases with NPD after ER for early gastric neoplasms. METHODS: After ER, 29 NPD lesions that had an associated pretreatment forceps biopsy specimen, were correctly targeted during ER, and had no cautery artifact on the resected specimen were included in this study. RESULTS: Sixteen lesions showed PD and 13 had no neoplastic pathology. The initial pretreatment forceps biopsy diagnoses of 29 NPD lesions were low-grade dysplasia (LGD) in 17 lesions, high-grade dysplasia (HGD) in seven lesions, and adenocarcinoma in five lesions, which after review were revised to PD in 19 lesions, LGD in four lesions, adenocarcinoma in two lesions, and no neoplastic pathology in four lesions. Overall, nine lesions (31%) were small enough to be removed by forceps biopsy, four NPD lesions (14%) were initially misinterpreted as neoplastic lesions, and 16 PD lesions (55%) were misinterpreted as NPD lesions on ER slides. CONCLUSIONS: Approximately half of the lesions initially diagnosed as LGD or HGD were subsequently classified as PD. Therefore, including PD as a subtype of gastric dysplasia could reduce the diagnostic discrepancy between initial forceps biopsy and ER specimens.

Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is the most common form of primary extranodal lymphomas. In most cases, it is developed as multifocal and mucosal lesions, and its initial diagnosis is made by biopsy of suspicious lesions on endoscopy. However, when gastric MALT lymphoma afflict submucosal site without typical mucosal lesion, further procedures are necessary for diagnosis, such as endoscopic mucosal resection and endoscopic ultrasonography. We recently experienced two cases of submucosal tumor-like gastric MALT lymphoma. Both cases were without any mucosal lesion. One case was confirmed by endoscopic mucosal resection, and the latter was by wedge resection. Treatment modalities included endoscopic mucosal resection, surgery, H. pylori eradication, and/or chemotherapy. Both cases achieved complete remission until our 18 months' and 16 months' follow up.

Acute renal failure secondary to acute pyelonephritis is developed rarely. But acute pyelonephritis is considered in differential diagnosis of acute renal failure, particularly in elderly patient. Elderly patient showed subtle symptoms or signs of infections and can be missed easily. We experienced two cases of acute renal failure secondary to acute pyelonephritis. In first case, one patient complained fever, chilling and right flank pain for 10 days. Three repeated blood and urine cultures showed E. coli, respectively. At admission serum creatinine showed 2.4 mg/dL and thereafter increased to 4.5 mg/dL, and then decreased to 1.7 mg/dL with antibiotic therapy and hydration at 14 days of admission. In second case, patient complained right flank pain, costovertebral tenderness and urinary difficulty at admission. Two repeated blood culture showed no growth, two repeated urine culture showed > 105 ml/dL of E. coli. At admission serum creatinine level was 2.69 mg/dL and then decreased to 1.7 mg/dL with antibiotic therapy and hydration at 14 days of admission.Acute pyelonephritis should be considered in differential diagnosis of acute renal failure in the elder ages, although this developed rarely. Early recognition and appropriate antibiotic treatment helps recover acute renal failure secondary to acute pyelonephritis.

BACKGROUND/AIMS: Magnifying endoscopy with narrow band imaging (ME-NBI) is a useful modality for the detailed visualization of microsurface (MS) and microvascular (MV) structures in the gastrointestinal tract. This study aimed to determine whether the MS and MV patterns in ME-NBI differ according to the histologic type, invasion depth, and mucin phenotype of early gastric cancers (EGCs). METHODS: The MS and MV patterns of 160 lesions in 160 patients with EGC who underwent ME-NBI before endoscopic or surgical resection were prospectively collected and analyzed. EGCs were categorized as either differentiated or undifferentiated and as either mucosal or submucosal, and their mucin phenotypes were determined via immunohistochemistry of the tumor specimens. RESULTS: Differentiated tumors mainly displayed an oval and/or tubular MS pattern and a fine network or loop MV pattern, whereas undifferentiated tumors mainly displayed an absent MS pattern and a corkscrew MV pattern. The destructive MS pattern was associated with submucosal invasion, and this association was more prominent in the differentiated tumors than in the undifferentiated tumors. MUC5AC expression was increased in lesions with either a papillary or absent MS pattern and a corkscrew MV pattern, whereas MUC6 expression was increased in lesions with a papillary MS pattern and a loop MV pattern. CD10 expression was more frequent in lesions with a fine network MV pattern. CONCLUSIONS: ME-NBI can be useful for predicting the histopathology and mucin phenotype of EGCs.
