Purpose : This study was designed to evaluate the clinical aspect of cysts which arised in the oral and maxillofacial region. Patients and Methods : We reviewed clinical record, radiograph, histopathologic and operative report of 155 patients who had been diagnosed as cysts and treated at the department of oral and maxillofacial surgery in Chonnam National University Hospital from January 2003 to December 2008. Gender, age, classifiaction, anatomic distribution, clinical sign and symptoms, treatment, complications and recurrence rate were studied. Results : 1. Among 155 patients, the male patients(64.5%) were more than the female(35.5%). 2. The average age ofthe patients was 37.2 years(ranging from 5 to 79 years). 3. In pathologic classification, radicular cyst and dentigerous cyst were most common cysts, irrespective of 73 cases(48.3%) and 35 cases(23.2%). 4. The frequently involved cystic regions were followed as mandibular molars(38.1%), and maxillary incisors(30.2%). 5. The frequent sequence of clinical symptoms was edema(29.9%), no symptom(18.9%), tenderness(13.9%), pain(11.5%) and abscess(9.4%). 6. The most prevalent treatment was the combination operation, such as cyst enucleation with extraction or endodontic treatment of the causative tooth(76.8%) 7. Among 155 cases, 2 cases that were treated using enucleation method were recurred(1.3%).

Between January, 1970 and August, 1989, a total of 81 patients whose age were more than 20 years of life, received total correction for tetralogy of Fallot. This report analyzed 70 patients among them and excluded the remaining 11 patients whose clinical data could not be found. Their mean age was 25.750.39 years[range 20 \ulcorner50]. The clinical manifestations were cyanosis and clubbing [64 pts], frequent URI[40 pts], anoxic spell [19 pts], infective endo-carditis[4 pts], brain abscess[3 pts], pulmonary tuberculosis[3 pts] and CHF, chest tightness, nephrotic syndrome, left hemiplegia, and tamponade. The types of right ventricular outflow tract obstruction were combined[46 pts], pure infundibular [21 pts] and pure valvular[3 pts]. Associated cardiovascular anomalies were PFO [27 pts], ASDi8 pts], LSVC[8 pts], aortic regurgitation [5 pts], right aortic arch, coronary artery anomalies, PDA and dextrocardia. Hospital mortality was 5.7%. The causes of death ware low cardiac output [2 pts], aggravation of CRF[1 pts] and brain damage[1 pts]. There was one late death because of residual intracardiac shunt and congestive heart failure. During the follow-up period, 16 patients were lost and the remaining 49 patients were asymptomatic and leading normal lives. Residual intracardiac shunt was detected in 5 patients with radionuclide single pass study but all of them had Qp / Qs ratio less than 1.5.

Acute disseminated encephalomyelitis(ADEM) is an uncommon immune-mediated inflammatory demyelinating disorder that typically affects the white matter of the central nervous system. Radiologic findings of acute disseminated encephalomyelitis are not pathognomomic. The differential diagnosis is always difficult. Occasionally, the clinical features, radiological and histopathological findings of patients with acute disseminated encephalomyelitis mimic the brain tumor or other space occupying lesions. The authors report a 6-year-old girl who presented with right hemiparesis two days after nausea and vomiting. Brain MRI of the patient revealed non-enhanced multiple cystic lesions in subcortical white matter of both cerebral hemisphere with prominent edema. One of the cystic lesions was resected to differentiate with metastatic tumor or inflammatory disease such as abscess and confirmed as the acute disseminated encephalomyelitis via various immunohistochemical stains. Pertinent literature is reviewed with discussion on this uncommon ADEM associated with multiple cystic lesions.

Pulmonary arteriovenous fistulas(PAVFs) is a rare disorder that occurs in two to three children per 100,000 population. It is presented as absence of intervening capillary beds between the pulmonary artery and vein with resultant persistent right to left shunt. Other causes include trauma, liver cirrhosis, malignancy and schistosomiasis. It is mostly asymptomatic, but it may present with respiratory difficulty, cyanosis, clubbed fingers induced by right to left shunt or hemoptysis, polycythemia and epistaxis. Major complications, such as brain abscess, brain embolism, paradoxical embolism and subacute infective endocarditis can be devastating, so therapeutic intervention is recommended in all patients. However, removal of low-resistance fistulas can aggrevate pulmonary hypertension, so detection of increased pulmonary pressure is important. We report two patients : One a 42 year-old male with PAVFs treated with coil embolization, and a 42 year-old female who was treated with anticoagulants due to pulmonary hypertension.

Unroofed coronary sinus syndrome is an uncommon anomaly which is caused by incomplete formation of the left atriovenous fold and it is usually associated with persistent left superior vena cava. It may be diagnosed by cardiac catheterization and cineangiography but, if it is not diagnosed, it can bring out significant complications due to right to left shunt, such as brain abscess, cerebral embolism, transient ischemic attack, arterial desaturation and there will reduced patient`s life expectancy. Therefore corrective operation was needed. A case of unroofed coronary sinus syndrome which combines with valvular heart disease was experienced at the department of thoracic & cardiovascular surgery of Kosin medical college. The patient was 49 years old female and she complained dyspnea on exertion for 2 yrs. Cardiac catheterization with cineangiography and both superior venacavogram were performed for diagnosis and she was diagnosed as unroofed coronary sinus syndrome combined with mitral and tricuspid regurgitation. Surgical correction was accomplished by reroofing of coronary sinus with pericardial patch, closure of atrial septal defect and annuloplasty of both atrioventricular valves. Postoperative results were satisfactory and course of recovery was uneventful. We report a case of unroofed coronary sinus syndrome with review.

E. histolytica has a simple life cycle with two stages: an infective cyst and an invasive trophozoite. It lives on humans as its host. Its infection occurs through the ingestion of the cyst form, and the disease begins when the trophozoite, converted at the small intestine, adheres to colonic epithelial cells with a latent period of two days to four months. In some instances, amoebic abscess formations can occur at the liver, lung, brain, or spleen via the lymphoid system. Rare cases of amoebiasis in neonates have been reported, much less any intrauterine infections in the world that may have occurred during the gestation period. We've recently experienced a case of neonatal amoebiasis that entailed after-birth vomiting and bloody stool. The infant seemed pre-infected with E. histolytica before birth.

Cerebral paragonimiasis is an important parasitic infestation found in Eastern Asia, West Africa, and Central/South America. It is frequently associated with abscess, granuloma or cystic lesions in chronic stage. Chronic symptoms include seizure, visual disturbance, movement and perception disorders, usually resulting from the spaceoccupying lesions. The authors report a case of chronic cerebral paragonimiasis combined with meningioma. A 69-year-old man presented with generalized seizure and impaired consciousness. CT scan and MR image of the brain revealed two intracranial lesions ; one was cerebral paragonimiasis in the left temporo-occipital lobe, and the other a huge falx meningioma. Two lesions were successfully removed in staged operations and the generalized seizure was controlled after removal of the cerebral paragonimiasis.

The experience with operative treatment for total correction of Tetralogy of Fallot at the department of Thoracic and Cardiovascular Surgery, Korea University Hospital from January, 1977, through April, 1983 was reviewed. Of the 29 patients reviewed, male to female occurrence ratio was 22:7 Type of V.S.D. was type II in 26 cases[90%] and total conus defect in 3 cases[10%]. Average size of V.S.D. was 19 mm. Type of Right ventricular outflow tract stenosis was highest frequency with pulmonary valvular and infundibular stenosis combined type in 21 cases[72%], and there were 8 deaths In this group. Type of R.V.O.T. reconstruction contains 2 cases of infundibulectomy only, 1 case of infundibulectomy with valvular commissurotomy, 2 cases of pericardial patch, 23 Cases of pericardial patch with Teflon or Dacron felt reinforced and 1 case of pulmonary valved conduit reconstruction. Operative mortality was higher in outflow patch through pulmonary valve ring. Overall mortality was 31%. Major causes of death and postoperative complications were low output syndrome, complete A-V block acute renal failure, ventricular fibrillation, bleeding brain abscess, and sudden cardiac arrest.

Cerebrospinal fluid (CSF) rhinorrhea usually occurs as a result of trauma including operation. Unheated CSF rhinorrhea may induce major morbidity such as meningitis and brain abscess, etc. This paper presents a review of four cases of traumatic CSF rhinorrhea Sites of CSF leakage were easily found out by intrathecal fluorescent dye injection. Surgery was performed by external ethmoidectomy approach and dural tear and bone defect was repaired with abdominal fat and free mucosal graft taken from amputated middle turbinates. We conclude that repair using free fat and mucosal graft via external ethmoidectomy approach could be accepted as the intial method of CSF rhinorrhea management.

In rare cases, levoatrial cardinal vein may occur as an isolated condition without additional congenital anomalies. Depending on the direction and flow of the shunt, this pathology may produce symptoms; alternatively, it may be asymptomatic, as in the case presented in this study. In asymptomatic cases, complications, such as paradoxical embolism and brain abscess, can arise later. In the 11-year-old patient whose case is presented here, the levoatrial cardinal vein was asymptomatic and incidentally detected. The percutaneous closure method was applied first. However, by 16 hours after the procedure, the occluder device had embolized to the iliac artery. Emergency surgery was performed; first, the occluder device was removed, and levoatrial cardinal vein ligation was then performed via a mini-thoracotomy. The symptoms, diagnosis, and treatment modalities of isolated levoatrial cardinal vein are discussed in the context of this case described herein.
