An 11-month-old, 19.5 kg, intact male Border collie was referred with intermittent left forelimb lameness to the Gyeongsang Animal Medical Center. The symptom was first discovered about 6 months ago, and it has gotten worse for the last 10 days with non-weight bearing on the left forelimb. During the physical examination, the patient showed painful reaction when the left shoulder was abducted. On radiographic assessment, a radiolucent line and some osteophytes were found in both humeral heads. Based on patient's clinical signs and radiographic findings, osteochondritis dissecans (OCD) was very suspicious. So, we decided to perform an arthroscopic surgery on left shoulder for definitive diagnosis and treatment because the right forelimb revealed no clinical signs. During arthroscopic technique, we found a large OCD flap on the caudo-central area of humeral head, and observed severe synovitis over a wide range on posterior area of the articular capsule. The large OCD flap was removed by a grasping forceps, and many joint mice were removed either. Curettage was performed using a curette on the articular surface until hemorrhage occurred, and articular capsule flushed with a lactated-ringer's solution. The patient was discharged on the same day without any specific abnormal status. Antibiotic, anti-inflammatory and analgesic drugs were administered. Mild lameness on left forelimb was observed in 2 weeks after surgery, but after 4 weeks, the patient showed complete normal gait without any lameness. Although surgical removal of OCD flap with arthroscopic was previously reported, We would like note that a large OCD flap can also be removed by arthroscopic surgery in this report.

목적: 성인의 단순성 골 낭종에서 스테로이드 주입법의 치료 효과를 알아보고자 한다. 대상 및 방법: 1998년 2월부터 2003년 2월까지 추시 가능한 11예를 대상으로 Needle aspiration 또는 천공술로 병변에 도달하여 낭종액을 배액후 Depo-medrol (methylprednisolone acetate, 신풍제약, Korea)을 1회 최소 80 mg에서 최대 200 mg까지 주입하였고, 추시 방사선 촬영은 투여 후 2주 간격으로 시행하였으며 약물 투여 후 6주에 시행한 단순 방사선 촬영에서 치유의 증거가 보이지 않을 경우, 8주에 추가적으로 스테로이드를 재 투여하였다. 최대 5회까지 시행하였고, 변형된 Neer의 분류법, Pentimalli 분류법, Scaglietti와 Sandra 분류법에 따라 결과를 판정하였다. 결과: 스테로이드의 한번 주입으로 치유된 예는 없었으며, 2회 주입 후 3예, 3회 주입 후 3예, 5회 주입 후 2예에서 치유되었고, 2예에서는 5회 주입 후에도 호전되지 않았으나, 증상의 변화가 없어 현재 관찰중이다. 1예에서는 2회의 스테로이드 주입 후에도 골 낭종의 크기가 증가되어 병적골절의 위험이 있어 수술적 치료를 시행하였다. Pentimalli 등의 단순 방사선 사진의 방사선학적 판정기준에 의해 결과를 평가하면, 1예에서 우수, 7예에서 보통이었고 3예에서 불량이었다. 결론: 스테로이드의 국소적 주입 요법은 성인에서도 효과적이며 일차적 치료법으로 고려할 수 있다.

Background: To evaluate the clinical significance of atypical squamous cells of undetermined significance (ASCUS) in PAP test in post-menopausal women and compare with reproductive age women. Materials and Methods: A total of 367 patients who referred to our gynecologic oncology clinic were included to the study between September 2012 and August 2013. Data for 164 post-menopausal (group 1) and 203 pre-menopausal (group 2) women with ASCUS cytology were evaluated retrospectively. Immediate colposcopy and endocervical curettage was performed for both groups and conization for all women with a result suggestive of CIN2-3. Histopathological results and demographic features of patients were compared between the two groups. Results: Mean age of the patients was $54.6{\pm}6.5$ years in group 1 and $38{\pm}6.6$ years in group 2. Some 14 (8.5%) of post-menopausal women and 36 (17.7%) of pre-menopausal women were current smokers (p=011). Totals of 38 (23.2%) post-menopausal and 64 (31.5%) pre-menopausal women were assessed for HPV-DNA. High risk HPV was detected in 7 (4.3%) and 21 (10.3%), respectively (p=0.029). Final histopathological results recorded were normal cervix, low grade cervical intra-epithelial neoplasia (CIN 1), and high grade cervical intra-epithelial neoplasia (CIN2-3). In group 1 results were 84.8%, 12.2% and 1.8%, respectively, and in group 2 were 71.9%, 23.2% and 4.9%. There were no cases of micro invasive or invasive cervical carcinoma in either group. Two cases were detected as endometrial carcinoma in the menopausal group (1.2%). Conclusions: In current study we found that preinvasive lesions were statistically significantly higher in pre-menopausal women than post-menopausal women with ASCUS. Cervicitis was more common in menopausal women. Therefore, we think that in case of ASCUS in a post-menopausal woman there is no need for radical management.

Cavernous sinus thrombosis is one of the major complications of abscesses of the maxillofacial region. The initial symptoms of CST are usually pain in the eye and tenderness to pressure. this is associated with high fluctuating fever, chills, rapid pulse, and sweating. Venous obstruction subsequently causes edema of the eyelids, lacrimation, proptosis, chemosis and retinal hemorrhages. Blindness is sometimes an accompaniment of cavernous sinus thrombosis when the infection also involves the orbit. There is also cranial nerve involvement (oculomotor, troclear, abducence) and ophthalmoplegia, diminished or absent corneal reflex, ptosis, and dilation of the pupil occur. The terminal stages bring signs of advanced toxemia and meningitis. Infections of the face can cause a septic thrombosis of the cavernous sinus. Furunculosis and infected hair follicles in the nose are frequent causes. Extractions of maxillary anterior teeth in the presence of acute infection and especially curettage of the sockets under such circumstances can cause this condition. The infection is usually staphylococcal. The inflection may spread directly through the pterygoid plexus of veins and the pterygomaxillary space and then ascend into the sinus or it may spread directly from the pterygopalatine space to the orbit. This is possible because of the absence of valves in the angular, facial, and ophthalmic veins. The treatment is empirical antibiotic therapy followed by specific anbibiotic therapy based on blood or pus culture. The inflection usually involves one side, however, it may easily spread to the opposite side through the circulus sinus. Unless it is treated early, the prognosis is poor even in this doses. Occasionally the antibiotics will not adequately resolve the septic thrombus, and death ensues. the use of anticoagulants to prevent venous thrombosis has been recommended, but the efficacy of such therapy has not been substantiated. Surgical access through eye enucleation has been suggested. We report a case which demonstrates cavernous sinus thrombosis by the infection after the functional neck dissection and the intraoral reconstruction with auriculomastoid fascio-cutaneous island flap.

Introduction: The incidence of bisphosphonate-related osteonecrosis of the jaw (BRONJ) has increased gradually in patients who have undergone surgical treatment for osteomyelitis. In this study, a retrospective analysis of BRONJ patients was carried out using the data of osteomyelitis patients treated surgically. Materials and Methods: Osteomyelitis patients, who underwent curettage, sequestrectomy, saucerization or decortications, and partial mandibulectomy at Seoul National University Dental Hospital from 2004 to 2010 were enrolled in this study. The patients were classified and categorized into two groups based on the surgical records and progress notes. One group comprised of patients with osteomyelitis and osteoporosis, and the other group included patients with osteomyelitis only. The epidemiological data of the BRONJ patients was analyzed to identify any trend in the incidence of BRONJ in osteomyelitis patients. Results: Among 200 patients who underwent surgical intervention for osteomyelitis, 64 (32.0%) were identified as having osteoporosis as the underlying disease. In these 64 patients, more than 81.3% had been prescribed bisphosphonates. Females were far more affected by BRONJ than males. The incidence of BRONJ also increased with age. The posterior part of the mandible was affected more frequently by BRONJ. Conclusion: Although the availability of potent antibiotics and increased oral hygiene care can reduce the overall incidence of osteomyelitis, BRONJ can increase the total incidence. To prevent BRONJ, it is recommended that an oral examination be performed before prescribing bisphosphonates. Moreover, the patients should be educated about the potential risks of dental procedures that might be causal factors for BRONJ. Furthermore, patient swho take bisphosphonates for the treatment of osteoporosis should undergo periodic follow up oral examinations to prevent BRONJ.

The purpose of this study was to study of the effects of the bioglass and the natural coral on healing process of the alveolar bone defects. Three adult dogs aged 1 to 2 years were used in this study. Experimental alveolar bone defects were created surgically with surgical bur and bone chisel at the furcation area of the buccal surface of the right and left mandibular 3rd, 4th premolars. Twelve experimental alveolar bone defects were devided into four groups according to the type of graft materials. The groups were as follows : 1. flap operation with root planing & curettage(Negative control group) 2. flap operation with autogenous bone(Positive control group) 3. flap operation with bioglass(BG group) 4. flap operation with natural coral(NC group) At 2, 4, and 8 weeks, the dogs were serially sacrificed and specimens were prepared with Hematoxylin-Eosin stain for light microscopic evaluation. The results of this study were as follows : 1. The defect areas were filled with granulation tissue at two weeks in negative control group. But in other groups, the appearance of connective tissues around graft materials were formed more densely and the response of inflammation by graft materials itself was not found. 2. In every control and experimental groups at two weeks, there was seen the accumulation of the formation of new bone trabeculae at the bottom of defects and gradually expanded toward the graft materials and in autogenous group there was slightly seen the formation of new cementum. 3. There was seen the erosion of central portion of bioglass particles at two weeks in BG group, and the erosion of the central portion was developed more progressively and was filled with bone-like tissues at eight weeks. 4. The natural coral particles were encapsulated by densely connective tissues and seen the formation of new bone tissues at four weeks and developed more new bone and cementum formation at eight weeks. From the results of this study, the bioglass and the natural coral may be biocompatible and have a weak adverse reaction to the periodontal tissues.
