A 13.5kg, 15-year-old male mongrel dog with anemia, anorexia, vomiting and abdominal distension was referred to the Veterinary Medical Center of the Tokyo University. Radiographic and ultrasonographic findings indicated primary splenic tumor. The tumor was located at body of the spleen, which was surgically removed by splenectomy. Histopathological examination of the mass revealed sarcoma type tumor derived from the mesenchymal origin. The patient was in good health after surgery but suddenly showed abdominal distension on the 3 months after. Radiographic findings indicated abdominal neoplasms. The 2nd operation was performed and removed the recurrent mast but suddenly died on the 4th day. Histopathological examination of the tumor was myxosarcoma.

Isolated injury to the pancreas after abdominal trauma is uncommon, and a delay in diagnosis and treatment can increase the morbidity and mortality. Therapeutic decisions with respect to pancreatic trauma are usually made based on the site of injury and the status of the pancreatic ductal system. In this report, we describe the surgical management of pancreatic head transection as an isolated injury following blunt abdominal trauma. A 55-year-old man presented with epigastric pain that radiated to the back. Abdominal computed tomography revealed a hematoma in the pancreatic head and upstream dilatation of the main pancreatic duct. Endoscopic retrograde cholangiopancreatography showed complete disruption of and contrast leakage from the main pancreatic duct in the pancreatic head region with a nonenhanced upstream duct. Emergency pancreaticoduodenectomy was successfully performed, and the patient was discharged on postoperative day 9 without any complications.

Traumatic flank hernia (TFH) is rare and prone to recurrence, which makes appropriate treatment challenging. No current guidelines define the optimal timing and method of repair. Meanwhile, recent advances in laparoscopic techniques are reshaping the options for the treatment of TFH. A dual approach that utilizes both laparoscopic and open methods has not previously been reported. Herein, we present the successful treatment of TFH after blunt trauma. A 46-year-old male patient underwent elective herniorrhaphy on hospital day 3, in which laparoscopic implantation of a sublay mesh and extracorporeal implantation of an onlay mesh were performed. Such techniques may be appropriate and result in feasible outcomes in hemodynamically stable patients with large TFH who are strongly suspected of having bowel herniation or concomitant intraperitoneal injuries. Larger studies are needed to assess the long-term results.

To our knowledge, this is the first case of concurrent diaphyseal left coracoid and left femoral fractures in a Eurasian eagle owl and its post-release survival in Korea. The femur was surgically repaired using an external skeletal fixator-intramedullary (IM) pin tie-in method, and the coracoid was repaired solely with an IM pin on day 6 after femur surgery. The eagle owl underwent a gradual rehabilitation process. The bird was successfully rehabilitated and released 101 d after initial presentation. The bird was monitored using a wildlife tracking device and was confirmed to have survived for over 5 mon in the wild.

Primary malignant neoplasm of the pericardium is very rare, Neoplastic involvement of the pericardium may result in rapidly developing hemorrhagic effusion. A 30-year-old male who occasionally suffered from chest tightness was referred to our hospital under the diagnosis of unstable angina. He presented with acute chest pain and severe dyspnea that had developed one day previously. The diagnostic investigations such as echocardiography, chest CT and magnetic resonance image suggested cardiac tamponade that was caused by rupture of the pericardial teratoma. An operation to remove the tumor and effusion was performed. The pericardial mass was completely excised, and the result of the frozen biopsy favored malignancy. The final pathologic report was malignant fibrosarcoma of the pericardium and no malignant cells were found on the cytology of the pericardial effusion. The patient had a smooth postoperative course and was referred to another hospital for additional radiation therapy. We report here on this case of cardiac tamponade that was caused by primary pericardial fibrosarcoma, and this required urgent diagnosis and surgical management.

The present study elucidated the effect of the selective inducible nitric oxide synthase (iNOS) inhibitor $N^6$-(1-iminoethyl)-L-lysine (L-NIL) on monosodium urate (MSU) crystal-induced inflammation and edema in mice feet. L-NIL (5 or 10 mg/kg/day) was administered intraperitoneally 4 h before injection of MSU (4 mg) into the soles of mice hindlimb feet. Twenty-four hours after MSU injection, foot thickness was increased by 160% and L-NIL pretreatment reduced food pad swelling in a dose dependent manner. Pretreatment of 10 mg/kg/day L-NIL significantly suppressed the foot pad swelling by MSU. Plasma level of nitric oxide (NO) metabolites and gene expression and protein level of iNOS in feet were increased by MSU, which was suppressed by L-NIL pretreatment. Similar pattern of change was observed in nitrotyrosine level. MSU increased the gene expression of tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-$1{\beta}$ and L-NIL pretreatment suppressed MSU-induced cytokines expression. The mRNA levels of superoxide dismutase and glutathione peroxidase1 were increased by MSU and L-NIL pretreatment normalized the gene expression. Phosphorylation of extracellular signal-regulated kinase 1/2 and p38 was increased by MSU, which was suppressed by L-NIL pretreatment. The mRNA levels of iNOS, TNF-${\alpha}$, and IL-$1{\beta}$ were increased by MSU in human dermal fibroblasts, C2C12 myoblasts, and human fetal osteoblasts in vitro, which was attenuated by L-NIL in a dose dependent manner. This study shows that L-NIL inhibits MSU-induced inflammation and edema in mice feet suggesting that iNOS might be involved in MSU-induced inflammation.

Purpose: The purpose of this randomized single-blind controlled trial was to elucidate the clinical and antimicrobial effects of daily phototherapy (PT) as an adjunct to scaling and root planing (SRP) in patients with chronic periodontitis. Methods: The study was conducted from December 2013 to May 2014 at Ewha Womans University Mokdong Hospital, Seoul, Korea. Forty-one patients with mild to moderate chronic periodontitis were randomly divided into two therapeutic groups in a 1:1 ratio: SRP+PT and SRP (control) groups. All participants underwent full-mouth SRP. PT was performed thrice a day for a month by using electric toothbrushes with embedded light-emitting diodes. Plaque index, gingival index, probing pocket depth (PPD), clinical attachment level (CAL), and bleeding on probing were assessed before (baseline) and four weeks after (follow-up) the treatment. Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Prevotella intermedia, Fusobacterium nucleatum, Parvimonas micra, Campylobacter rectus, Eikenella corrodens, Streptococcus mutans, and Streptococcus sobrinus levels were detected by a real-time polymerase chain reaction at the same points in time. Results: The clinical parameters improved in both the groups. At the follow-up assessment, PPD was significantly decreased in the SRP+PT group (P=0.00). Further, PPD and CAL showed significantly greater changes in the SRP+PT group than in the SRP group (PPD, P=0.03; CAL, P=0.04). P. gingivalis and T. forsythia levels decreased in this group, but no significant intergroup differences were noted. Conclusions: Adjunctive PT seems to have clinical benefits, but evidence of its antimicrobial effects is not sufficient. Long-term studies are necessary to develop the most effective PT protocol and compare the effectiveness of PT with and without exogenous photosensitizers.

The cocktails of two $^{131}I$ labeled Monoclonal antibody (MCAB) (Anti CA 19-9 F$(ab')_2$ + Anti CEA $F(ab')_2$ fragment), which react specially, with human gastrointestinal cancers, were administered to 10 patients with colorectal (7), stomach(2) and pancreas(1) cancer for scintigraphic detection. All patients were known or postoperatively recurrent cases, and serum tumor markers, CA 19-9 and CEA, were measured with immunoradiometric assay, just before immunoscintigraphy (ISG). The tumor marker's level in serum is not correlated with positive tumor uptake in ISG. The sensitivity and specificity of ISG in detection of 21 tumor sites, based on surgery, CT, ultrasonography and pathology, were 90.5% and 100% One case of colon cancer showed gall bladder metastasis, which was neglected on CT study. Tumor/non tumor uptake ratio of radiolabelled antibody were progressively increased from day 3 to day 7 during study. We summerized as follows 1) The use of cocktails of CEA and CA 19-9 MCAB $F(at')_2$ increased sensitivity and specificity in ISG. 2) Delayed imaging (later than 5 days) increases sensitivitv and specificity due to exclusion of nonspecific iodine accumulation in stomach and lung. 3) Second tracer technique is essential for anatomical landmark by use of a double isotope scan, but subtraction technique, a possible source of artifacts, is no longer necessory when delayed imaging is performed. 4) It may be possible to use two MCAB cocktails of CA 19-9 and CEA in Radioimmunodetection of stomach and pancreas cancer. In conclusion, ISG using MCAB cocktails, $F(ab')_2$ fragment of anti CA 19-9 and Anti CEA, provide additional opportunity for tumor localization and detection of colorectal and other G-I cancer, such as stomach and pancreas.

A case of bladder prolapse through a patent urachus is reported in a female infant born with a large, red, tubular mass inferior to the umbilical cord. A cystic mass communicating with fetal bladder was detected by prenatal ultrasound performed at $20^{+2}$ weeks of gestation. A fetal MRI was also performed to confirm the diagnosis and to exclude associated fetal anomalies. At $40^{+4}$ weeks, the cystic mass was no longer present and a new small solid mass was noted at the fetal abdominal wall. After birth, a protruded mucosal mass inferior to the umbilical cord was noted, and catheterization confirmed communication between the protruded mass and the urinary bladder. On the second day of life, reduction of the bladder and partial resection of the urachus was performed. A voiding cystourethrogram showed good bladder capacity and no vesicoureteral reflux. The patient voided well and was discharged after 10 days. Here, we present a case of urinary bladder prolapse through a patent urachus, diagnosed by fetal sonography and this is the first case reported that was treated by simple excision without complication.

Plastibell is one of the three most common devices used for neonatal circumcision in the United States, with a complication rate as low as 1.8%. The Plastibell circumcision device is commonly used under local anesthesia for religious circumcision in male neonates, because of cosmetic reasons and ease of use. Occasionally, instead of falling off, the device may get buried under the skin along the shaft of the penis, thereby obstructing the normal flow of urine. Furthermore, the foreskin of neonates is highly vascularized, and hence, hemorrhage and infection are possible when the skin is cut. Necrosis of penile skin, followed by urethral obstruction and renal failure, is a serious surgical mishap requiring immediate corrective surgery and medical attention. We report a case of fulminant urosepsis, acute renal failure, and pyelonephritis in a 4-day-old male neonate secondary to impaction of a Plastibell circumcision device. Immediate medical management was initiated with fluid resuscitation and mechanical ventilation; thereby correcting life threatening complications. Pediatricians and Emergency Department physicians should be cognizant of the complications from Plastibell circumcision device in order to institute appropriate and timely management in neonates.
