To determine the usefulness on fine needle aspiration cytology(FNAC) of bone lesions and the complementary role of FNAC and percutaneous needle biopsy, 75 cases of FNAC taken from bone lesions were analyzed. Correlations with histopathology were possible in 47 cases, including 14 cases of simultaneous core biopsy and 33 cases of subsequent open biopsy due to inadequate aspirates. Among 75 cases, 4 cases were benign tumors and tumor-like lesion, 11 cases were malignant primary bone tumors, 17 cases were metastatic tumors, and 43 cases were nonneoplastic bone lesions. The aspirates were adequate in 35 cases(46.7%), in all of which the discrimination between benignancy and malignancy was possible. The main reason for Inadequate aspirates was due to hypocellularity. In the cases of aspiration and core biopsy simultaneously done, the diagnostic accuracy of aspiration, core biopsy, and both were 57%(8/14), 78.6%(11/14), and 92.9%(13/14), respectively. We conclude that a final diagnosis based on cytology is possible with the adequate aspirates and the clinical and radiological findings. Also we confirm the complementary role between FNAC and core biopsy in bone lesions.

Background: The purpose of this study is to evaluate the functional outcomes of reverse total shoulder arthroplasty (RTSA) and to assess factors affecting the patients' subjective satisfaction after RTSA. Methods: Forty-three patients (mean age, $75.0{\pm}5.2years$) who underwent RTSA for cuff tear arthropathy or irreparable cuff tears with preoperative magnetic resonance imaging and pre- and postoperative radiographs at 1 year, and whose various functional outcomes including pain visual analogue scale (VAS), simple shoulder test, Constant score, American Shoulder and Elbow Surgeons score, and active range of motion were evaluated preoperatively and at the last follow-up (>12 months) were enrolled. The outcome parameter was set as a satisfaction scale. Various clinical and radiographic factors were analyzed, and their correlations with postoperative satisfaction were evaluated. Results: All functional scores, VAS pain score, and active forward flexion showed significant improvement after surgery (all p<0.001). Twenty-nine patients were satisfied with the results and 14 were dissatisfied. The presence of pseudoparalysis (p=0.028) and worse preoperative function (all p<0.05) were related with higher satisfaction. Any radiologic parameters did not affect patients' postoperative satisfaction. Conclusions: All patients showed a good functional outcome after RTSA, however the patients' subjective postoperative satisfaction was affected by preoperative functional status (higher satisfaction in poor preoperative function), not by radiological findings.

Desmoplastic fibroma is a rare. benign intraosseous fibroblastic tumor. which is locally aggressive. It is osseous counterpart of soft tissue fibromatosis. The authors experienced the patient who complained persistent mouth opening limitation with mild swelling on the left mandibular angle area. After careful analysis of clinical. radiological and histopathological findings. we diagnosed as desmoplastic fibroma of the mandible. The results were as follows: 1. Main clinical symptoms were mouth opening limitation which had been persistent for 9 months and mild swelling on the left mandibular angle area. 2. Radiographs showed the radiolucent lesion and expansion of lingual cortex. CT finding is homogeneous soft tissue mass with expansion of left mandibular ramus. Destruction of medial wall of ramus and invasion to adjacent soft tissue is also seen. 3. Histopathologically, plump spindle shaped fibroblasts arranged in bundles or fascicles are observed. The cells of tumor are infiltrating into muscle fiber with destruction of bony trabeculae and merged with surrounding salivary gland.

Chronic recurrent multifocal osteomyelitis (CRMO) is a rare idiopathic inflammatory bone disease characterized by pain and swelling without any detectable infectious factors, the main feature is mild to moderate bone pain. CRMO commonly develops in the metaphyses of long bones and clavicles in children or adolescents. Chronic nonbacterial osteomyelitis (CNO) is the isolated form of CRMO and the etiology of CNO is still unclear. This report describes a rare case of CNO of the mandible in an 8-year-old female patient. On the basis of clinical, histological, and radiological findings, CNO was diagnosed. The patient was asymptomatic after surgical curettage followed by antibiotic therapy. Cone beam CT scan revealed a nearly completed bone healing after three months.

Acid ingestion can cause not only caustic injury on esophagus and stomach but also fatal outcome through systemic complications. We report the case of a patient who died early after severe caustic injury with strong acid. A 38-year-old man who ingested about 400ml of hydrochloric acid of unknown concentration was transferred to our hospital from a private clinic, in which he was managed with gastric irrigation through a nasogastric tube. He was complaining dyspnea and abdominal pain. Physical examination demonstrated tenderness and rebound tenderness on epigastric region. Severe metabolic acidosis and leukocytosis were noted. Radiological findings suggested perforation of gastrointestinal tract, although the physical signs were not typical. Endoscopy revealed caustic injuries of grade I on esophagus and of grade Ⅲ on stomach, which indicate more severe injury on the stomach than on the esophagus. Exploratory surgery was recommended but unfortunately not permitted by his family. Despite intensive measures, his vital signs deteriorated rapidly and he died 50 hours after the ingestion.

Purpose : Authors attempted to evaluate the effect on explanation of pathogenesis and stress management as the initial care of temporomandibular disorders. Materials and methods : The materials were 634 patients with temporomandibular disorder, who had been referred to our Department of Dentistry, Wonju Christian Hospital during recent 5 years. We examined about clinical aspects of temporomandibular disorders, such as, major signs of temporomandibular joint disorder, life environment and habits, radiological findings of temporomandibular joint and electromyography of masseter muscle. The patients were treated by explanation of TMJ pathogenesis and stress management. After that, the patient were evaluated about the effect in third week. Results : The result was more favorable (96.5% success rate) without intolerable signs of temporomandibular joint disorder. Conclusion : The explanation of TMJ pathogenesis and stress management were thought as the very effective care in management of patients with temporomandibular disorder.

By the early half of the 20th century, the most common cause of spontaneous pneumothorax was considered to be tuberculosis. But recently ruptures of the subpleural emphysema and/or blebs are considered as the major causes of spontaneous pneumothorax. To evaluate the causes of spontaneous pneumothorax, the authors reviewed the 96 patients who were consecutively diagnosed and treated by thoracotomy for spontaneous pneumothorax at the Department of Thoracic and Cardiovascular Surgery, Seoul Advenist Hospital, from May, 1988 to April, 1993. The patients who had clinical and radiological evidence of tuberculosis or other specific parenchymal lung diseases were excluded from this review. All patients were negative for tuberculous bacilli on sputum studies. The pathologic results were as follows : subpleural emphysema[25], blebs[27], subpleural emphysema and blebs[25], pleural fibrosis[10], tuberculosis[8], and parasitic granuloma[1]. Three of the patients who were diagnosed to be tuberculosis by pathologic findings were progressed to active pulmonary tuberculosis on the follow-up chest PA films. The authors conclude that all patients with spontaneous pneumothorax must be evaluated periodically for tuberculosis and that patients who were diagnosed to be tuberculosis by postoprative pathologic report need the administration of the prophylactic antituberculous drug, because the prevalence of tuberculosis remains relatively high rate in our country.

A 6-month-old, weighing 2.8 kg, female, domestic short-haired cat presented with open fracture at right distal radius about a month ago. Based on radiological findings, hyperplasia at the right radioulna and left humerus was found. Results of the cytological examination were inflammatory reaction and reactive osteoblast. Distal radial ostectomy proceeded with necrotic bone debridement. Three weeks after operation, the radial bone lysis was seen on radiograph but clinical condition improved. Hyperplasia at the right radioulna and left humerus was dissolved. Two months after operation, she can use her both forelimbs despite right elbow have been diagnosed as arthrosclerosis because of periosteal reaction. Six months after operation, clinical symptoms of limbs were not detected. In this case, open fracture was treated through delayed surgical debridement procedure, therefore hematogenous osteomyelitis occurs at another forelimb. The longer a wound remains open, the more likely it is that infection will develop. The infection can occur to fracture bone and seed from hematogenous spread to another normal bone. In conclusion, when open fracture occurs, early antibiotic treatment and urgent surgical intervention are recommended.

The urinary bladder retroflexion, flipped over backwards into the pelvic canal, by trauma has been rarely reported in dogs. This paper describes clinical and radiological features of urinary bladder retroflexion in two dogs with a history of traffic accident. The main clinical signs were hind limb lameness, severe pain and dysuria. Radiography and ultrasonography were performed to evaluate the patient's damages. No remarkable findings were observed except pelvic fracture on survey radiograph. On cystourethrography, caudal displacement and retroflexion of the bladders were identified. Cystopexy was performed and the bladders were repositioned. After surgery one dog with severe azotemia and bilateral hydroureteronephrosis was deteriorated noticeably and euthanized by request of the owner, while the other dog was recovered no recurrence of the problem by 12 months post-surgery. It should be considered that contrast study and serial assessment in urinary tract be important to demonstrate the evidence of bladder retroflexion and evaluate the prognosis in dogs with severe trauma.

Spinal meningeal cyst of the sacrum is uncommon congenital lesion. We experienced two cases of sacral meningeal cyst, so called Tarlov's cyst, who presented with radiating pain. Magnetic resonance imaging is a highly effective way of locating and approximating the size of these entities, which generally appear as intraspinal masses of low intensity on T1-weighted and high intensity on T2-weighted images, similar to cerebrospinal fluid(CSF). We evaluated 2 patients who had Tarlov's cyst diagnosed with conventional MRI. The clinical features, radiological findings, gross appearances of the lesion at surgery, surgical technique, histopathological features of the cyst wall, and surgical outcome are described. We conclude that excellent result can be expected in the case of symptomatic Tarlov's cyst by surgical decompression.
