An 8-year-old, shih-tzu female dog was referred due to neurological signs including paraparesis and back pain. On the complete blood count, hematologic analysis showed elevated leukocytosis. Serum biochemical analysis revealed elevated serum alkaline phosphatase concentration and C-reactive protein concentration. On the neurologic exam, the dog was suspected to have thoracolumbar myelopathy. On magnetic resonance imaging, there were masses within the spinal canal at L1-3 intervertebral disc space that were located dorsal to spinal cord. It was hyperintense on T1-, T2-weighted magnetic resonance images, Fluid-attenuated inversion recovery, and fat suppression images. The contrast-enhanced T1-weighted images showed no enhancement. The lesions were well circumscribed. The spinal cord was compressed and displaced ventrally by the mass. After removal of the masses via L1-L3 dorsal laminectomy, pyogranulomatous inflammation was confirmed by histopathological examination. Six months after surgery, the dog recovered uneventfully and remained fully ambulatory with no neurological deficits. This case demonstrates the utility of magnetic resonance imaging for the diagnosis of spinal canal pyogranulomatous inflammation.

Angiogenesis is one of the essential processes that occur during wound healing. It is responsible for providing immunity as well as the regenerative cells, nutrition, and oxygen needed for the healing of the alveolar socket following tooth extraction. The inappropriate removal of formed blood clots causes the undesirable phenomenon of alveolar osteitis (AO) or dry socket. In this review, we aimed to investigate whether enhanced angiogenesis contributes to a more effective prevention of AO. The potential pro- or anti-angiogenic activity of different materials used for the treatment of AO were evaluated. An electronic search was performed in the PubMed, MEDLINE, and EMBASE databases via OVID from January 2000 to September 2016 using the keywords mentioned in the PubMed and MeSH (Medical Subject Headings) terms regarding the role of angiogenesis in the prevention of AO. Our initial search identified 408 articles using the keywords indicated above, with 38 of them meeting the inclusion criteria set for this review. Due to the undeniable role of angiogenesis in the socket healing process, it is beneficial if strategies for preventing AO are directed toward more proangiogenic materials and modalities.

Neuroblastoma is the most common extracranial solid tumor in children, and accompanies various clinical symptoms including hypertension. Hypertension is associated with catecholamines secreted from the tumor, and is usually not severe. We report one case of malignant hypertension with cardiac failure in a patient with adrenal neuroblastoma, successfully treated with adrenalectomy. A 3 year-old boy complained of protrusion of the chest wall. Physical examination revealed severe hypertension with cardiac failure. The levels of metabolites of catecholamine were increased in blood (norepinephrine >2000 pg/mL) and urine (norepinephrine 1350.5 ug/day). Abdominal CT showed a 7 cm-sized solid mass arising from the right adrenal gland. After stabilizing the hemodynamics with oral phenoxybenzamine, right adrenalectomy was performed. Pathological diagnosis was a ganglioneuroblastoma. The hypertension and cardiac failure were resolved after tumor removal.

Gastric hemangioma in the neonatal period is a very rare cause of upper gastrointestinal bleeding. We present a case of hemangioma limited to the gastric cavity in a 10-day-old infant. A huge, erythematous mass with bleeding was observed on the lesser curvature side of the upper part of the stomach. Surgical resection was ruled out because the location of the lesion was too close to the gastroesophageal junction. Medical treatment with intravenous $H_2$ blockers, octreotide, packed red blood cell infusions, local epinephrine injection at the lesion site, application of hemoclip, and gel-form embolization of the left gastric artery did not significantly alter the transfusion requirement. Hemostasis was achieved with endoscopic argon plasma coagulation (APC). After two sessions of APC, complete removal of the lesion was achieved. APC was a simple, safe and effective tool for hemostasis and the ablation of gastric hemangioma without significant complications.

We report the experiences of pump-driven continuous venovenous hemofiltration therapy in three children with acute renal failure. The all three patients required mechanical ventilation and needed the support of vasopressors. Renal replacement therapy was needed to meet the metabolic and fluid balance, but intermittent hemodialysis and peritoneal dialysis were not feasible because of hemodynamic instability and concurrent infection. We instituted pump-driven continuous venovenous hemofiltratlon (CVVH), and immediate improvement of pulmonary edema and successful removal of retained fluid were observed. Urea clearance also was satisfactory. During the filter running time, significant thromboembolic event or rapid drop of systemic blood pressure were absent. We concluded that the CVVH is an effective and safe method of renal support for critically ill pediatric patient.

This is a case report of successful surgical correction of coarctation of the aorta associated with the patent ductus arteriosus and the persistent left superior vena cava. The patient was a 15 year old girl and congenital heart anomaly was suspected at the sixth month after birth. Afterward there has been no embarrassing symptoms until the day of operation except slight dyspnea on exertion, The diagnosis of coarctation of the aorta and the patent ductus arteriesus detected by physical signs and X-ray studies including aortography. In the first place, coarctation of the aorta was corrected with following procedure: partial resections of the aortic wall just above and below the coarctating line of the aorta and removal of diaphragmatic structure of coarctation performed by. cross clamping aorta above and below coarctation, and then the defect of the aortic wall was closed by lateral aortorrhapic suture with atraumatic needle 3-0 silk continuously [Fig. 6]. In the second place, the patent ductus arteriosus was closed with double ligation method. The persistent left superior vena cava left as it has been, because there has been no evidence of hemodynamic abnormal shunt. After operation, excellent result was obtained; blood pressure in the upper and lower extremities was normalized and subjective complains of hypertension in the upper extremity was disappeared.

Dental impression materials often become contaminated with patients' saliva and blood which creates the potential for cross-infection. It was the purpose of this study to investigate the effects of disinfection of three different rubber impression materials with four different disinfecting solutions. Polysulfide, vinyl polysiloxane and polyether impression materials were mixed according to the manufacturer's directions and samples were formed on a stainless steel model. On removal from the standard model, impressions were immersed in a disinfectant (acid-potentiated glutaraldehyde, phenollic compound, chlorine compound, iodophor) at room tempera tures for ten minutes. After disinfection, the distance between reference points(linear dimension) was measured using the non-contact automatic cordinate measuring projector(MZ-1, Nikon). Through statistical analyses on the data from this study,. the following conclusions were obtained. 1. Polysulfide, vinyl polysiloxane impressions were disinfected without dimensional change.(p>0.05) 2. Polyether impressions which were immersed in acid-potentiated glutaraldehyde were statistically different from control group.(p<0.05) But the amount of shrinkage(0.04%) would not be clinically significant. 3. By immersion of polysulfide, vinyl polysiloxane, polyether impressions in Banicide, Biocide, Multicide plus, sodium hypochlorite for ten minutes, clinically accurate impressions were obtained without dimensional change.

Objective : Removal of blood from subarachnoid space with a lumbar drainage (LD) may decrease development of cerebral vasospasm. We evaluated the effectiveness of a LD for a clinical vasospasm and outcomes after clipping of aneurysmal subarachnoid hemorrhage (SAH). Methods : Between July 2008 and July 2013, 234 patients were included in this study. The LD group consisted of 126 patients, 108 patients in the non LD group. We investigated outcomes as follow : 1) clinical vasospasm, 2) angioplasty, 3) cerebral infarction, 4) Glasgow outcome scale (GOS) score at discharge, 5) GOS score at 6-month follow-up, and 6) mortality. Results : Clinical vasospasm occurred in 19% of the LD group and 42% of the non LD group (p<0.001). Angioplasty was performed in 17% of the LD group and 38% of the non LD group (p=0.001). Cerebral infarctions were detected in 29% and 54% of each group respectively (p<0.001). The proportion of GOS score 5 at 6 month follow-up in the LD group was 69%, and it was 58% in the non LD group (p=0.001). Mortality rate showed 5% and 10% in each group respectively. But, there was no difference in shunt between the two groups. Conclusion : LD after aneurysmal SAH shows marked reduction of clinical vasospasm and need for angioplasty. With this technique we have shown favorable GOS score at 6 month follow-up.

This study was carried out to investigate the changes of chemical and sensory properties and cholesterol lowering effect of milk treated with $\beta$-cyclodextrin to reduce cholesterol and supplemented with evening primrose oil (EPO). The average cholesterol removal rate was 93.5%. The thiobarbituric acid (TBA) absorbance increased proportionally to storage period and amount of EPO addition. TBA absorbance was significantly different in the EPO-added groups from that in unadded groups in all periods. The production of short-chain free fatty acids (FFA) increased with longer period of storage. From 6 days of storage, the amounts of short-chain FFA in 6 and 10% EPO-added groups were significantly different from other groups. The scores for all sensory characteristics indicated that sensory quality decreased with both storage time and increasing amount of EPO. Oxidative off-flavor and off-taste were more intense with higher amounts of EPO addition and longer storage period. Also, the higher the amount of EPO addition, the lower overall scores throughout the 15 day storage. Feeding 10% EPO-supplemented cholesterol-reduced milk increased high density lipoprotein (HDL) in male Sprague-Dawley rats by 76%, which is significantly different from the control (27%).

Tissue 02 tension is an important guide in detection of the general condition in critical patients. The tissue 0, is more difficult to measure with 0, sensor in skeletal muscle and subcutaneous tissues to present. But it is much easier to measure 0, tension in bladder urine with Censini catheter in Foley catheter than in tissue. We have measured 0, tension in bladder urine, main pulmonary artery and radial artery in 16 patients in chest surgical department of Yonsei University. College of Medicine from September 26 to December 22, 1981. Six patients were male and ten patients were female. Their ages ranged from 8 to 43 years. The correlation equation between the simultaneously measured PuO2 and PvO2 was found to be Ypvo2=4.04 + 0.88 Xpuo2 [r=0.88, p<0.0001] in regression curve with computer [HP/3,000, Program: SPSS] in the Yonsei University. Measurement of 0, tension in bladder urine and MPA will be rather simple, rapid and reproducible method than that of the 0, tension in tissues. But the speed of 0, consumption in urine is fast and so the 0, tensions in bladder urine were measured as soon as possible after they were collected. They were no complications or morbidity during measurement of 0, tension in these procedures except spontaneous removal of radial arterial cannulas in 2 patients.
