Malignant Sertoli cell tumor was diagnosed in a 5-year-old male Shih Tzu dog. Clinical features of the dog were anorexia, urinary incontinence, constipation, anemia, alopecia, and epistaxis. The dog also had unilateral cryptorchid testis in the abdomen. Several abdominal and thoracic masses were identified on radiography. Grossly, the cryptorchid testicular mass was markedly enlarged to 8 cm in diameter. On cut surface, firm and well demarcated milk-white neoplastic areas were irregularly separated by white fibrous bands. Histologically, the testicular mass was diagnosed as tubular pattern Sertoli cell tumor. In addition, abdominal and mediastinal lymph nodes metastasis were found. Immunohistochemically, the tumor cells were strongly positive for vimentin and neuron specific enolase, but negative for S-100 and cytokeratin.

Lymphomas of the nasal sinuses are relatively uncommon and represent less than 1% of all head and neck malignancies. Most common symptoms are nasal obstruction, epistaxis, rhinorrhea. We report a case of primary extranodal diffuse large B-cell non-Hodgkin's lymphoma in nasal sinuses accompanying with exophthalmos. A 70-year-old male patient was referred to our hospital with exophthalmos and severe septal deviation. We conducted endoscopic biopsy with septoplasty and biopsy result was diffuse large B-cell lymphoma. He received chemotherapy(R-CHOP) and radiotherapy. At follow-up, he remained free of disease.

Three dogs were referred with epistaxis and facial deformity. Computed tomography (CT) scan identified masses in the bilateral nasal cavity with soft tissue attenuation and contrast enhancement. These masses had caused adjacent bones lysis, especially lysis of cribriform plate that extended to the intracranial region. Base on histopathology and CT imaging results, tumors were diagnosed as nasal carcinomas at stage 4. Three dogs were treated with stereotactic radiation therapy (SRT). These dogs received 30-35 Gy from 3-5 daily treatments (7-10 Gy per treatment). The sizes of tumors decreased the most on follow-up CT images at one month after treatment. Recurrence was confirmed between 3 and 5 months after completing SRT. The survival time of dogs treated with SRT were 110, 190, and 210 days, respectively. This study confirmed that SRT could treat canine nasal carcinomas with cribriform plate lysis without causing serious radiation toxicities. Follow-up CT examination is considered at 1 month and 3 to 6 months after SRT to accurately evaluate the prognosis and the timing of recurrence.

Hypercoagulability is the most common coagulopathy seen in dogs with neoplasia, whereas a hypocoagulable state is relatively rare. A 16-year-old spayed female miniature Schnauzer presented with bilateral epistaxis, bilateral hindlimb swelling, and lameness. Previously, the dog was diagnosed with intermediate grade solid carcinoma after mastectomy, and then showed generalized ecchymoses on the abdomen and bilateral hindlimbs on presentation. Laboratory tests revealed a hypocoagulable state, including thrombocytopenia, hypofibrinogenemia, and delayed prothrombin and activated partial thromboplastin time. Thromboelastography demonstrated a prolonged K time with a decreased alpha angle and low maximal amplitude, reflecting a decrease in clot strength. The hypocoagulable state of disseminated intravascular coagulopathy was speculated based on the presence of an underlying tumor, clinical symptoms, and laboratory results of the hypocoagulable state. This case shows the incidence of hemostatic dysfunction as a paraneoplastic syndrome in a dog with mammary gland carcinoma.

The nasotracheal tube (NTT) is frequently used in oral and maxillofacial surgery and is generally considered a safe means of protecting the airway while ensuring an adequate surgical field. The most common complication associated with NTT is epistaxis, and only a few cases of foreign body obstruction have been reported. In this case report, the authors aimed to highlight the potential for NTT obstruction following surgery. A 24-year-old female patient, who underwent mandibuloplasty and rhinoplasty at a local clinic, was referred to our hospital patient due to dyspnea and edema on her right mandibular angle. Even with NTT, patient continued to experience mild dyspnea and tachypnea, so a T-piece was applied. However, tachycardia accompanied by a sudden worsening of dyspnea was observed, and bag-valve-mask ventilation was initiated promptly. But oxygen saturation remained unimproved, so an emergency cricothyroidotomy was performed. After 4 hours, the patient's condition stabilized. Upon examination, the previously inserted NTT was identified, and a blood clot approximately 10 cm long at the NTT tip was discovered, causing lumen obstruction. The obstructions of NTT can lead to serious or life-threatening consequences if left unobserved or ignored. Therefore, when a patient with an NTT complains of dyspnea, clinicians should promptly investigate the possibility of partial NTT obstruction to ensure the airway's security.

Background and Purpose : Emergencies in the school setting occurs frequently. Therefore, the role of first responders is important. General teachers in elementary schools are expected by first responders in school emergencies. This study attempted to assess needs and demands assessment on the first aid education of general teachers in elementary schools. Method : The subjects of this study were 71 general teachers from 8 elementary schools. Data were collected by the questionnaire during the period from March 19 to April 13, 2007. The data were analyzed through frequency, Cronbach's ${\alpha}$, Independent Two samples t-test, paired T-test, One Way ANOVA, Pearson's Correlation by SPSS win 12.0. Result : 1. It showed that 47.9%(34 persons) of general teachers answerd that they experienced emergencies in elementary school setting. Experienced emergencies were wounds(cut, laceration, abrasion etc.) 79.4%(27 persons), bleeding(including epistaxis) 64.7%(22 person), fracture(including dislocation, sprain) 44.1%(15 person), sting or bite 29.4%(10 persons). 2. It showed that 95.8%(68 persons) of subjects answerd that first aid education are necessary. Also 91.5%(65 persons) of subjects answerd that will be educated first aid if opportunities is given. 3. The total mean showed $2.39{\pm}.40$ in necessities of first aid education and $2.17{\pm}.36$ in needs of first aid education by 3 points Likert scale. Ranking 1 in necessities and needs of first aid education was bleeding control. 4. The total mean in necessities and needs of first aid education showed statistically significant differences(t = 3.453, p = .002). 5. The necessities of first aid education showed significant positive correlations with necessities and needs of first aid education(r = .521, p = .002). Conclusion : These results suggest that education program of first aid on elementary general teachers must be developed through necessities and needs assessment of first aid education and instructors must searched methods to increase needs of first aid.

This study was conducted for the development of recording system of students' health problems, and for the application of International Classification of Health Problem in Primary Care(ICHPPC) as a tool of morbidity classification in school health care. The data were collected from 12th of September to 24th of September in 1988. The objects were composed of health problems written by 10 school nurses who take service in the elementary school. The results were as follows: 1. The features of students' health problmes. The health problems of students were 68 problems from the total numbers of 361 codes of ICHPPC. The 93.4% of health problems was contained in 20 descriptive diagnoses and 97.0% was contained in 30 descriptive diagnoses. According to frequency of main health problems, There were abrasion, scratch and blister(26.7%); disorder of stomach function, other disease of stomach and duodenum (20.4%); headache(10.6%); bruise and contusion (5.3%); acute URI (5.0%); laceration and open wound(4.6%); Insect bite and sting(4.0%); epistaxis(3.4%): abdominal pain(2.6%): superficial tissue(1.7%). Out of all health problems, Category 17(accident, injury and poisoning was 44.7%. and Category 9(digestive system Disease) was 22.2%. 2. Applicability of ICHPPC by the school nurses. School nurses used 68 codes, among the total number of 361 codes from ICHPPC. According to ICHPPC method, school nurses can classified more diverse health problems systematically and objectively than that in other studies on school nurses activities. ICHPPC was found as a useful and applicable tool of morbidity classification in the practice of school nurses.

Heat stroke in a dog is a life-threatening syndrome characterized by a high body temperature over $41^{\circ}C$, by the central nervous system dysfunction, and by multiple organ dysfunction. A 11-month-old male American Pit Bull Terrier was presented to clarify the cause of death to diagnostic laboratory. This dog showed clinical signs such as high body temperature ($42^{\circ}C$), severe tachypnea, hematochezia, epistaxis and hemoptysis after transportation at hot summer time. At necropsy, there were hemorrhages in skin, serosa of stomach and small intestine, and also dark red fluid in lumen of intestine. Histopathologic examination revealed extensive hemorrhages in stomach, muscle, skin, and tongue. In microbiology, pathologic bacteria such as Pasteurella, Boedetella, Salmonella, Clostridium, and circulating virus in Korea such as CDV, CIV, CAV, CHV, CCV, CPIV were negative except CPV. There were many gross and microscopic lesions suggesting hest stroke while pathologic agents and related lesions were not detected. Therefore we diagnosed this case as heatstroke.
