Objectives: To investigate the prevalence of different primary reasons for endodontic referrals and the clinical symptoms of the referred cases. Materials and Methods: Clinical data of total endodontic treatment cases (1,014 teeth) including endodontic referral cases (224 teeth) between January 1, 2010 and December 31, 2012, at Kangdong Sacred Heart Hospital, were investigated retrospectively. The one major reason for referral, the clinical symptoms, and the resulting treatment procedures of referral cases were recorded. The percentages of clinical symptoms of the endodontic referral cases and the total endodontic treatment cases were compared by ${\chi}^2$ test for each symptom. Results: Persistent pain was the most frequent reason for endodontic referral (29.5%), followed by presence of gingival swelling and sinus tract (24.1%), and apical radiolucency (12.9%). Referrals in cases involving endodontic difficulties such as canal calcification, broken instruments, post, perforation, and resorption were less than 5.0%, respectively. The percentages of four major clinical symptoms of pain, apical radiolucency, previous endodontic treatment, and gingival swelling and sinus tract were significantly higher in the endodontic referral cases than those in the total endodontic cases (p = 0.001). Among the included referral cases, 72.8% were treated with nonsurgical endodontic treatment only. Teeth other than the referred teeth were diagnosed as the origin of the problem in 5.8% of the referrals. Conclusions: The high prevalence of pain, apical radiolucency, previous treatment, and gingival swelling and sinus tract in endodontic referral cases suggest that these symptoms may be what general practitioners consider to be difficult and refer to endodontists.

A 6-year-old intact male Doberman pinscher presented with a thin soft stool and urinary signs. On radiography, three masses were observed in the caudal abdomen. One mass was described as a large, round, mineralized mass, with an "eggshell" appearance. The second mass was located caudal to the mineralized mass, and the third mass was located between the two masses. The second and the third masses had a soft tissue density. Ultrasonography was performed to identify the features and the origins of the masses. The first mass contained a large amount of anechoic fluid and had a thin wall; it was determined to be a cyst. Strong acoustic shadowing artifact was created by the mineralized cystic wall. Caudal to the cyst, the second mass was shown to be the prostate. A hypoechoic stalk connected the prostate and the cyst, which represented the cyst as a paraprostatic cyst with mineralization. The third mass was the normal urinary bladder. The cyst was removed surgically and confirmed by histopathologic examination. This report described typical clinical findings, diagnostic imaging, and treatment of a paraprostatic cyst.

Hepatocellular carcinoma (HCC) is a primary hepatic neoplasms in dogs. Three types of HCC such as massive, nodular and diffuse form were reported. Massive HCC is most common and has relatively better prognosis than other forms because this type of HCC can be removed surgically and has low frequency of relapse or metastasis. Diagnostic image can provide useful information for shape and internal structure of the hepatic mass as well as the location and adhesion or invasiveness of the mass to establish surgical plan to remove the mass safely. In this study, we investigated diagnostic features of massive HCC in 5 dogs. Radiography showed soft tissue mass in cranial abdomen in 3 dogs. On ultrasonography, all dogs had a solitary hepatic mass with mixed echo pattern with anechoic cysts, which represented necrosis and hemorrhage. The radiographic and ultrasonographic findings of affected hepatic lobe were compared with the macroscopic findings through laparotomy. Computed tomography was performed to check metastasis and figure out the origin of the mass in two dogs. Ultrasonography is useful and relatively sensitive examination for diagnosis and planning for surgery in canine massive HCC.

A 13-year-old, spayed female, Yorkshire terrier was presented with a history of vomiting and diarrhea. Radiographic and ultrasonographic studies suggested rupture of right renal cyst. Left kidney had increased cortical echogenecity with indistinct corticomedullary junction on sonogram. Unilateral nephroureterectomy of right kidney was performed. Histopathologic examination of the resected renal mass confirmed a renal cystadenocarcinoma. To the best of our knowledge, it is the first case report of renal cystadenocarcinoma in a small breed dog in Korea.

Pancreatic pseudocyst is one of the most common pancreatic mass lesions developed following acute or chronic pancreatitis. Two dogs were presented with nonspecific clinical signs such as abdominal pain, vomiting and depression and diagnosed as pancreatic pseudocysts through percutaneous ultrasound-guided aspiration. Pancreatic pseudocyst may contain pancreatic juice, so leads the deteriorate state of patient through pertinent inflammation and autodigestion of pancreas. In this study, the clinical signs and pancreatic lesion were improved after aspiration. Percutaneous ultrasound-guided aspiration can provide the diagnostic information through cytology and lipase and amylase concentration, and be selected as the first choice for treatment.

To compare differences of LOS between the group of inpatients via referral centers(the referral group) and the group of inpatients via different routes (the general group) and analyze factors which determine the difference. The 9,484 cases of newly inpatients of Mar., Jun., Sep., Dec. of year 2003 were used for the data. We calculate the Case-mix index of length of stay($CMI_{LOS}$) to compare LOS adjusted with the disease as the ratio of a patient' LOS to all patients' average LOS by 21 classification diagnosis group. We conducted t-test to compare differences of $CMI_{LOS}$ between two groups and multiple regression to analyze factors determining the difference. $CMI_{LOS}$ was 0.94 in the referral group, which was smaller than 1.01 in the general group. LOS was 7.5days in the referral group, which was 0.6day shorter than that in the general group. Multiple regression also showed that $CMI_{LOS}$ was smaller in the referral group than in the general group after controlling patients' general characteristics, diagnostic information variables. The referral centers can be said to playa role in decreasing LOS. We suggest that variety of depth studies on referral centers should be continued at the strategic level of hospital management using additional medical informations.

암컷 4살령치 미니어쳐 핀셔가 간헐적인 기침 증상으로 본 원에 내원하였다. 흉부 방사선 검사와 초음파 검사를 통해 좌측 폐의 전엽이 경화되고 흉수가 동반된 것을 확인하고 개흉술을 통해 염전된 폐엽을 절제하였다. 본 증례는 흥부 초음파 검사를 통해 폐염전을 진단하여 신속히 수술적인 치료를 적용함으로써 좋은 예후를 얻을 수 있었다. 폐염전은 대형견종에서 호발하는 것으로 알려져 있으나 근래 소형 견종에서의 발생 보고가 증가하고 있다. 본 증례는 소형 견종 중 미니어쳐 핀셔에서는 처음 보고되는 폐염전 증례로 갑작스러운 호흡 곤란을 보이고 흉부 방사선 검사와 초음파 검사상 흉수와 폐경화, 비정상적인 폐엽의 방향 등의 이상 소견을 보이는 경우, 본 증례와 같이 이전에 폐염전이 발생한 보고가 없거나 드문 소형 견종에서도 폐염전을 감별 진단 리스트에 포함시켜야 할 것으로 생각한다.

4개월 된 수컷 진도 견에서 좌측 후지 파행이 발생하였다. 방사선 검사에서 양측 경골 견인 골단 아래 작은 골편이 관찰되었으나, 견인 골단의 변위는 없었다. 그 후 양측 경골 조면 부위의 골밀도는 방사선 투과성에서 비투과성으로 변화하였다. 좌측 경골은 수술 후 회복되었으나, 우측 경골은 보존적 처치로 자가 치료되었다. 본 환자는 경골조면의 부분 견열골절로 진단되었으며, 이는 개에서 'Osgood-Schlatter disease'로 불려져 왔던 질환이다. 이 증례는 환자의 경골조면 부분 견열골절의 순차적인 방사선학적 영상 변화에 대한 유용한 임상적 정보를 제공할 수 있을 것으로 생각한다.
