Despite anticoagulation, systemic embolization and anticoagulant-related hemorrhage are the major drawbacks of heart valve replacement with mechanical prostheses. Among many predisposing factors, inadequacy of anticoagulation is the most important one. Surgery can be reserved for patients who do not response to thrombolytic therapy, We have experienced 3 cases of prosthetic valve thrombosis treated by thrombolytic therapy by use of urokinase and heparin. Two patients fully recovered and returned to their employments and active lives but 1 patient,died of intracerebral hemorrhage and infarction. We report prosthetic valve thrombosis thrombolytic therapy with urokinase and heparin which was detected and serially followed by 2-dimensional echocardiography, cinefluoro copy, and monitoring of Swan-Ganz catherterized pressures.

Cholelithiasis is rarely recognized in children, especially in infants. Hemolytic disorders, long-term total parenteral nutrition (TPN), congenital anomalies of the biliary tree leading to stasis of bile flow, congenital IgA-deficiency, furosemide treatment, and prolonged fasting have been reported as predisposing factors for cholelithiasis in childhood. Hemolytic disease of the newborn due to anti-E has rarely been reported as a risk factor for cholelithiasis. We report a case of gallbladder stones in a neonate associated with anti-E antibody hemolytic disease.

Basal cell carcinoma(BCC) is malignant epithelial neoplasm arising from either basal cells or pluripotential appendageal cells of the epidermis. BCC is the most common cutaneous malignancy, especially in sun-exposed sites, such as head and neck. But its occurrence on the finger is very rare. We experienced a case of BCC arising on the dorsal surface of the middle finger of a young woman. This case is not associated with any predisposing factors such as basal cell nevus syndrome, trauma, or preexistent dermatosis. Following surgical removal of the lesion, the defect was covered with full-thickness skin graft. The patient has presented no sign of relapse for 1 year of clinical follow-up. We report this rare case of BCC in terms of age and location.

Dementia is the neurodegenerative process that affects cognition, behavior and function and one of the most prominent diseases of dementia is Alzheimer's disease(AD). AD is a dementing illness characterized clinically by the progressive and irreversible deafferentation of the limbic system, association neocortex and basal forebrain. A number of conditions are known to be predisposing risk factors for AD. In several of these, initiation of glial-mediated inflammatory pathways as a mechanism of AD is getting a lot of attention. On the other hand, a biochemical marker for monitoring the onset and progression of the disease would be a valuable tool for disease management. Also such a marker might be used as an end point in clinical intervention protocols. This biochemical marker will have the potential for identifying subjects afflicted with the disease and possibly for monitoring the onset and longitudinal progression of the disease. Here we have reviewed the latest papers of different approaches to AD. Of course, there is a section of PET which is very useful clinically nowadays.

Cause of pituitary apoplexy has been known as hemorrhage, hemorrhagic infarction or infarction of pituitary adenoma or adjacent tissues of pituitary gland. However, pituitary apoplexy caused by pure infarction of pituitary adenoma has been rarely reported. Here, we present the two cases pituitary apoplexies caused by pituitary adenoma infarction that were confirmed by transsphenoidal approach (TSA) and pathologic reports. Pathologic report of first case revealed total tumor infarction of a nonfunctioning pituitary macroadenoma and second case partial tumor infarction of ACTH secreting pituitary macroadenoma. Patients with pituitary apoplexy which was caused by pituitary adenoma infarction unrelated to hemorrhage or hemorrhagic infarction showed good response to TSA treatment. Further study on the predisposing factors of pituitary apoplexy and the mechanism of infarction in pituitary adenoma is necessary.

Invasive cervical resorption is a relatively uncommon form of external root resorption. It is characterized by invasion of cervical region of the root by fibrovascular tissue derived from the periodontal ligament. This case presents an invasive cervical resorption occurring in maxillary lateral incisor, following damage in cervical cementum from avulsion and intracoronal bleaching procedure. Flap reflection, debridement and restoration with glass ionomer cement were performed in an attempt to repair the defect. But after 2 mon, more resorption extended apically. Considering root stability and recurrence potential, we decided to extract the tooth. Invasive cervical resorption in advanced stages may present great challenges for clinicians. Therefore, prevention and early detection must be stressed when dealing with patients presenting history of potential predisposing factors.

A retrospective analysis was performed with 30 cases of canine urolithiasis presented in the period between January and December 2001 The miniature schnauzer (6 cases), maltese (5 cases) and Shih Tzu (4 cases) had higher incidences than other breeds. Canine urolithiasis occurred from one year till 12 years, but the most prevalent age was 3 years. Urinary calculi occurred more often in males (63%) than females. The most prevalent anatomic locations of calculi were urinary bladder (8 of 22 cases) and urethra (13 of 22 cases) in males and urinary bladder (10 of 18 cases) in females. The major mineral component of calculi was struvite (72%). In male dogs, out of 15 cases, 10 cases were struvite and 5 cases were calcium oxalate uroliths. And, in female dogs, 8 of 10 cases were struvite. In some cases, mineral composition and urine pH was not matched. In conclusion, in the dogs with predisposing factors for urolithiasis, regular examination or proper diet should be added to prevent the disease. And the mineral composition of calculi should not be predicted solely by the pH or crystal component of urine.

The author made a clinical study of IIO cases of empyema thoracis who were diagnosed and treated at department of chest surgery, chosun university hospital, during the period of December 1979 through June 1983. 1. In age and sex distribution, 45 cases [41%] was under the age of 15 years, 65 cases [59%] was above the age of 15 years. The ratio of male to female was 2.6:1. 2. The predisposing factors were pneumonia 45 cases [41%] and pulmonary tuberculosis 40 cases [36.5%]. 3. The cardinal symptoms were dyspnea, chest pain, fever, cough in order. 4. Etiologic organisms were confirmed in 69% which requested in 87 cases. Staphylococcal infection were 19 cases, Streptococcal infection were 13 cases, pneumococcal infection were 11 cases. 5. In treatment of empyema, thoracentesis 4 cases, closed thoracotomy 50 cases, open drainage 29 cases, decortication 14 cases and thoracoplasty 13 cases. In children, only thoracentesis and closed thoracotomy was favorable result in treatment. 6. 103 cases were discharged with recovery and improvement but 7 cases were early discharged by their economic or personal condition without improved.

The author observed a case of the malignant fibrous histiocytoma of the mandible in 23 aged male patient, who had come to the Infirmary of Dental College, Yonsei University. With the help of careful analysis of radioraphic and clinicopathologic findings, the author had obtained the results as follows. 1. Lesion occured at 22 years of age. 2. Traumatic history or other special predisposing factors were not seen. 3. Lesion appeared as a intra osseous primary tumor not showing any metastatic change. 4. The author have concluded this disease as a malignant fibrous histiocytoma of the mandible according to serial findings.

Dissecting aortic aneurysm is a life threatening condition which necessitates prompt diagnosis and management. Between January 1987 and September 1993,58 patients was admitted to our department. Mean age at admission was 53 years.[range 25-82]. Clinical findings included chest pain in 48 cases[83%],renal failure in 12[20%],aortic insufficiency in 11[19%] and stroke in 9[15%]. Predisposing factors were hypertension in 50 cases[86%],Marfan`s syndrome in 6[10%] and diabetes melitus in 1 [2%]. 23 patients[ type A 13,type B 10 ] underwent surgical treatment. Surgical technique for type A included graft replacement of ascending aorta in 7 cases,graft replacement and aortic valve resuspension in 3,and Bentall`s operation in 3 cases. Type B patients were operated when specific indications applied. There were three [Two in type A and 1 in type B] deaths in the operation group and nine [ 5 in type A and 4 in type B] deaths in the medical group. These results support our current policy in the treatment of dissecting aortic aneurysm.
