Purpose : By analyzing seroma volume changes in the patients who underwent Partial breast radiation therapy after breast conserving surgery, we try to contribute to the improvement of radiotherapy effect. Materials and Methods : Enrolled 20 patients who underwent partial breast radiation therapy by ViewRay MRIdian System were subject. After seeking for the size of the removed sample in the patients during surgery and obtained seroma volume changes on a weekly basis. On the Basis of acquired volume, it was compared with age, term from start of the first treatment after surgery, BMI (body mass index) and the extracted sample size during surgery. And using the ViewRay MRIdian RTP System, the figure was analyzed by PTV(=seroma volume + margin) to obtain a specific volume of the Partial breast radiation therapy. Results : The changes of seroma volume from MR simulation to the first treatment (a week) is 0~5% in 8, 5~10% in 3, 10 to 15% in 2, and 20% or more in 5 people. Two patients(A, B patient) among subjects showed the biggest change. The A patient's 100% of the prescribed dose volume is 213.08 cc, PTV is 181.93 cc, seroma volume is 15.3 cc in initial plan. However, while seroma volume decreased 65.36% to 5.3 cc, 100% of the prescribed dose volume was reduced to 3.4% to 102.43 cc and PTV also did 43.6% to 102.54 cc. In the case of the B patient, seroma volume decreased 42.57% from 20.2 cc to 11.6 cc. Because of that, 100% of the prescribed dose volume decreased 8.1% and PTV also did to 40%. Conclusion : As the period between the first therapy and surgery is shorter, the patient is elder and the size of sample is smaller than 100 cc, the change grow bigger. It is desirable to establish an adaptive plan according to each patient's changes of seroma volume through continuous observation. Because partial breast patients is more sensitive than WBRT patients about dose conformity in accordance with the volume change.

A 6-month-old, intact male Great Pyrenees (35 kg) was referred with 2 weeks continuous left forelimb lameness to the Chonbuk Animal Medical Center, College of Veterinary medicine, Chonbuk National University. The lameness became worse three days before being referred to the hospital. Upon the physical examination, the patient had pain when the left shoulder joint was palpated, and the lameness was visible in the left forelimb during ambulation on gait examination. There were no remarkable findings on radiological and neurological examination. Osteochondritis dissecans (OCD) was suspected based on medical history and gait tests. As a definitive diagnosis could not be made, exploratory arthroscopic surgery was performed to examine the inside of the shoulder joint. During the operation, mild bicipital tenosynovitis, synovitis and OCD which was located on the caudal medial area of humeral head were revealed. Arthroscopic procedures were used for the treating OCD, including the removal of the OCD flap and debriding of the subchondral defect until hemorrhaging by use of an electrical burr. The patient was discharged a day after surgery. After 2 weeks, the patient again presented at the hospital due to complications, including inflammation of the surgical lesion because of licking and seroma within the subcutaneous tissue. Antibiotics were administered and an aseptic bandage was applied. And simple surgical operations were performed for the removal of the cyst and seroma. Eleven weeks following arthroscopy, the lameness was completely resolved. Arthroscopy has the advantage of allowing gross examination inside the joint capsule. Due to this advantage, arthroscopy is one of the best advanced options for diagnosis in dogs with undiagnosed joint pain.

Purpose: Seroma formation is still major complication of abdominal donor site after TRAM flap surgery in spite of various efforts to reduce seroma formation such as closed suction drain. We performed a clinical study, that quilting suture at abdominal donor site can prevent seroma formation. Methods: Between May 2002 and September 2008, we performed 600 breast reconstructions using a unilateral TRAM flap except patients who has smoking history or abdominal scar. We performed 300 breast reconstructions without quilting sutures (A: Experimental group) until January 06, and after then 300 reconstructions with quilting sutures (B: Control group). We compared total drain output (mL), time to drain removal (days), and donor site complications between two groups. Results: There were no statistical difference at BMI (p=0.28) and time to remove suction drain between two group. (A: 8.37, B: 9.69) (p=0.40) But, total drain output was reduced with quilting suture. (A: 432.5, B: 495.2) (p=0.005) And also complication rate was decreased, such as seroma formation, epigastric bulging. (A: 1%, B: 7%) (p=0.005) Conclusion: Quilting suture is a simple and reliable method to reduce seroma formation and abdominal donor site complication.

Primary peritoneal psammocarcinoma is a rare type of serous carcinoma that is characterized by the massive formation of psammoma bodies and the invasion of adjacent organs. A 55-year-old female who previously underwent a hysterectomy presented to the emergency room with severe abdominal pain. Contrast-enhanced CT revealed an intra-abdominal calcific mass. Initially, it was thought to be a heterotopic ossification due to the previous pelvic surgery with intact ovaries. However, this was diagnosed as a primary peritoneal psammocarcinoma. Primary peritoneal psammocarcinoma is a very rare disease entity that should be considered a differential diagnosis in patients with normal ovaries, massive ossification in the pelvic cavity, and calcific peritoneal nodules.

Introduction : No drain technique during parotidectomy had been introduced to reduce postoperative morbidity and to minimize hospital stay in a few previous publications. Since the authors have applied this technique in select patients for several years, we wanted to evaluate the feasibility and usefulness of no drain parotidectomy. Material & Methods : We retrospectively reviewed the medical records of 96 patients who underwent superficial or total parotidectomy by one surgeon from May 2005 to July 2012. The decision on drain insertion was made by the operator at the end of the surgery. The patients were categorized as drain insertion group and no drain group. Results : The patients who have smaller tumors and benign lesions were more frequently chosen into no drain group. Hospital stay was shorter in no drain group than in drain insertion group. Although no drain group showed increased number of acute complications such as seroma and hematoma, the complications were mild and could be controlled easily at the outpatient clinic. Conclusion : No drain technique during parotidectomy could be done relatively safely in select patients and it could reduce hospital stay.

Two dogs (Case 1 weighing 27 kg, Case 2 weighing 42 kg) were referred with hindlimb lameness. On physical examination, there was moderate pain on stifle joint testing and mild cranial translation on cranial drawer testing in Case 1. This translation was obvious when the patient was under general anesthesia. Case 2 showed discomfort during hyperextension of the stifle joint, but no significant cranial translation under general anesthesia. Joint effusion was detected on radiography in both cases. Based on physiologic and radiographic examinations, cranial cruciate deficiency was suspected, so exploratory arthroscopy was performed. Arthroscopy revealed partial rupture of the cranial cruciate ligament (CrCL) in both cases. Case 1 showed unstable partial CrCL rupture, while Case 2 had stable CrCL rupture. Tibial tuberosity advancement (TTA) was carried out as planned. Seroma occurred one week postoperatively in Case 2, and was removed surgically. The patients returned to satisfactory weight-bearing ambulation 5 months after initial surgery. Based on the results of these cases, TTA appears to be a useful procedure in the treatment of CrCL partial rupture.
