Clinical observations were made on a total 104 cases of spontaneous pneumothorax during the period of 5 years from MAR. 1971 to MAR. 1976 at the Dept. of Chest Surgery, Korea University Medical College. The ratio of male to female cases was 7.4 : 1 in male predominance, and age distribution was 73% of the total cases within the 15-40 age range. There were 56 patients (53.8%) of right sided pneumothorax and 44 patients (42.3%) of left sided pneumothorax, 8 patients presented bilateral spontaneous pneumothorax. The etiologic factors were tuberculous origin in 42.3%, rupture of bullae or blebs in 15.4%, acute pulmonary infection in 3.8%, pulmonary paragonimiasis in 2.9%, cysticercosis 1%, Marfan's syndrome in 1.9%, unknown causes in 32.7%. In all 104 cases, closed chest tube thoracostomy were performed for reexpansion of collapsed lung. In 50 cases of 104 cases, intrapleural instillation of Quinacrine HCl (Atabrine, Winthrop Laboratories, New York, N.Y.) thru the chest tube was used to control of recurrent pneumothorax, and compared observation with 54 cases control group of closed chest tube thoracostomy only. In both groups, 1) cure rates were 63% in control group and 88% in Atabrine group. 2) average duration of inserted chest tube were 5.6 days in control group and 5.7 days in Atabrine group.

Fahr disease (FD) is a rare neurological disorder characterized by presence of abnormal and associated cell loss in certain areas of the brain, mostly in basal ganglia, thalamus, cerebellum and subcortical areas. Approximately two-thirds of the patients are symptomatic. The most common neurological manifestations include movement disorders, cognitive impairment, cerebellar signs and speech disorders. We report one case of estimated FD through brain computed tomography (bilateral calcifications of basal ganglia, thalamus, centrum semiovale, subcortical white matter of occipital lobes, cerebellum). At the first time of treatment, he complained of tremors in his upper limbs. We diagnosed the patient as deficiency of qi (氣) and movement of phlegm-heat-wind (痰熱風動) type according to symptoms and treated by herbs and acupuncture of oriental medicine. During treatments, we evaluated how well the oriental medical treatments were working using visual analogue scale (VAS) and amplitude of hands. After the oriental medical treatments about tremor, VAS dropped from 10 to 2 and amplitude of hands from 20 mm to 2 mm, but the ratio of brain calcifications was not changed. This study suggests that oriental medical treatments can be applicable to improve FD.

Objective : Stroke is leading cause of death and more importantly it is cause of serious disability. The effective treatment of acute ischemic stroke still remains a challenge to modern medicine. Recent clinical trials have shown that carotid endareterctomy(CEA) provide overwhelming benefits compared with medical therapy in preventing subsequent stroke for symptomatic carotid stenosis. For the asymptomatic ones, the data are less compelling, but highly suggestive that CEA do have benefits in properly selected patients. Materials and Methods : To investigate the clinical manifestations of carotid stenosis and results of CEAs, authors analyzed retrospectively 19 CEAs in 16 patients from June 1986 to June 1999. Age of patients ranged from 55 to 76 years(median, 66) and male to female ratio was 14 to 2. The duration of follow-up was 1 to 144 months (median, 26). All of CEAs were done on the side of stenosis more than 80% and bilateral CEAs were done in three. Six CEAs were performed in asymptomatic patients. Results : Seventeen of 19 CEAs showed excellent results and complication rate was low although ipsilateral ischemic stroke occurred in two. Conclusion : CEA may be a valuable surgical treatment for ischemic stroke caused by carotid stenosis and also for prevention of stroke of asymptomatic patients with carotid stenosis.

This study was performed to determine the effect of three different concentrations of soy-isoflavones on calcium and phosphorus balance in either sham-operated or ovariectomized female rats. Seventy-two 16-week old Sprague-Dawley rats underwent sham operation or bilateral ovariectomy. They were provided diets containing different levels of soy iso-flavones for 6 weeks: 50 ppm (Jow isoflavone intake; LI) , 250 ppm (medium isoflavone intake; MI) and 500 ppm (high isoflavone intake; HI). The subsequent fecal and urinary excretions of calcium and phosphorus were then measured. In the sham-operated rats, body weight gains and food efficiency ratio of the MI and HI groups were significantly lower than the control group while food intake was not different. However, there was no significant difference in the ovariectomized rats. The fecal excretion of calcium was significantly lower in the LI, MI and HI groups than the control group in sham operated rats, and significantly lower in the HI group than the control group in ovariectomized rats. Also, apparent ab-sorption rate of calcium and phosphorus did not show any significant difference among groups. Urinary excretion of calcium and phosphorus was significantly lower in the HI group than the LI group in the sham-operated rats. Urinary excretion of calcium was significantly higher in the control ovariectomized rats than in the control sham-operated rats. Retention of calcium and phosphorus did not show any significant difference in both groups. From the above result, we see that isoflavone intake increases calcium retention through an increase in calcium absorption and also suppresses the increase of calcium excretion in urine in ovariectomy. Therefore, it is suggested that isoflavone intake is recommended for menopausal women who experience sharp bone loss due to the decrease in estrogen honnone.

Objectives : The purpose of this clinical report was to investigate the general characteristics of the patients with nasal polyps and estimate the efficacy of the oriental medical treatment on nasal polyps. Methods : We performed a clinical analysis of 50 patients who visited Kabsan oriental clinic due to nasal polyps. We inquired into distribution of age, sex, operation history related to nose, grade of nasal polyps, efficacy of treatment, etc. Results and Conclusions : 1. The sex ratio was 2.3 : 1. The average age was 40.02 years. 2. In the nasal operation history, inexperienced patients were 35 cases and experienced patients were 15 cases. 3. In the region of nasal polyps, there were 35 cases of bilateral types of nasal polyps, which is mon than in unilateral types. In the number of nasal polyps, multicentric types of 26 cases were similar in the number with solitary type of 24 cases. 4. In the predisposing or concomitant diseases, chronic sinusitis was the most frequent followed by allergic rhinitis, chronic rhinitis, septal deviation chronic otitis media, asthma, tonsilitis and allergic dermatitis. 5. In the main symptoms, nasal obstruction was the most important. In the concomitant symptoms, patients had frequent rhinorrhea, smell disturbance, postnasal drip, headache, etc. 6. The average treatment period was 3,58 months and the average number of treatment was 12.94 sessions. 1. In the amount of herbal medicine, 2 and 3 Ji(劑) were the most. The most frequently used herbal medicine to treat was Hyangbujamogeuntanggagam(香附子茅根湯加減) 8. In the change of grade after treatment, Grade I was the most.

Objective: The objective of this study was to evaluate the osseointegration of narrow-diameter implant with trapezoid-shape and to evaluate the effect of coronal microthreads on trapezoid-shape narrow-diameter implant. Materials and Methods: The experimental narrow-diameter implants were classified into two groups according to absence or presence of coronal microthreads: trapezoid-shape narrow diameter implant (TN group) and trapezoid-shape narrow-diameter implant with microthreads (TNM group). They were installed alternately in bilateral mandible in three dogs. After 8 weeks, the animals were sacrificed. Resonance frequency analysis, removal torque test, and histometric analysis were performed. Results: Statistically higher implant stability quotient (ISQ) values were observed in TNM group than in TN group at the time of implant installation. However, significant ISQ values difference was not observed between groups at 8 weeks. Both groups showed significantly increased ISQ values at 8 weeks, compared to the time of implant installation. There was no significant difference between groups in removal torque test. Bone-implant contact ratio also showed no significant difference between groups in total and coronal part. Conclusion: Within the limitation of this study, it could be concluded that the trapezoid-shape design on narrow-diameter implant showed successful ossointegration, and the microthreads on coronal part did not result in significant bone-implant contact and biomechanical stability at 8 weeks.

Purpose: This study is designed to analyse etiology and bone pattern at the first visit using cone-beam computed tomography (CBCT) and to evaluate the treatment outcome of conservative treatment in temporomandibular disorder (TMD) patients with rheumatoid arthritis (RA). Methods: One hundred condyles in 50 subjects with RA were chosen among the patients who presented to the Department of Oral Medicine of Pusan National University Dental Hospital, diagnosed as TMD. Condylar bone changes were classified by normal, erosive bony change, proliferative bony change and combined group (erosive bony change+proliferative bony change). They were treated conservatively with physical therapy, medication, behavioral therapy and/or occlusal stabilizing splint therapy. After 3 months on average, patients were re-evaluated with regards to subjective symptoms and the clinical findings were investigated. Results: TMD patients with RA have behavioral contributing factors such as parafunctional habit. The results that analyse bone pattern at the first visit using CBCT proliferative bony changes group (32.6%) were more common than erosive bony changes group (15.2%). In comparison between unilateral and bilateral bony change in temporomandibular joint, the ratio showed no significant differences. After 3 months of conservative treatments, pain, noise, limitation of motion (LOM) were markedly improved regardless of occlusal splint therapy. However only LOM was significantly improved through occlusal splint therapy during 3 months. Conclusions: TMD patients with RA had similar behavioral contributing factors and characteristics of CBCT images shown in general TMD patients and also similar response to conservative treatment so it is difficult to differentiate. Therefore when TMD patients show symptoms corresponding to clinical diagnostic criteria of RA at the first visit, serological testing should be conducted and through this, early diagnosis and treatment of RA should be initiated.

This study is a retrospective analysis of 1244 cases of the inguinal hernia in children under the age of fifteen years who were operated at the department of pediatric surgery, Inje University Busan Paik Hospital from March, 1997 to February, 2007. The ratio of male to female was 3.6:1. The type of hernia was indirect in all of the cases. The hernia was on the right side in 656 cases (53.9 %), left side in 467 cases (37.5 %), and bilateral in 121 cases (9.7 %). The hernia presented most frequently in infants under age 12 months; 364 cases (29.2 %). Fifty-nine cases (21.7 %) were in female and 305 cases (31.3 %) in male. There were 428 cases (33.6 %) in 1-3 years age group, 295 cases (23.7 %) in 4-6 years, 112 cases (9.0 %) in 7-9 years, 39 cases (3.1 %) in 10-12 years and 16 (1.2 %) in 13-15 years. The content of hernia sac was small bowel (59 %), omentum (31 %) in males and the ovary and tube (54 %) and small bowel (26 %) in female. The incidence of combined operation at the time was 3.2 %, and consisting of orchiopexy (67.5 %), frenulotomy (12.5 %), appendectomy (10 %), circumcision (5 %), and fistulotomy (5%). The incidence of combined disease was 2.8 % and consisting of undescended testis, Hirschsprung's disease, idiopathic hypertrophic pyloric stenosis, imperforate anus, and congenital heart disease. After unilateral inguinal hernia repairs, contralateral hernias developed in 34 patients. The laterality of the primary site of hernias were left in 19 cases (55.8 %), and right 15 cases (44.1 %). The 936 cases (75.2 %) were operated under general anesthesia; Mask bagging 663 cases (53.2 %), endotrachea intubation 257 cases (20.6 %), and laryngeal mask 16 cases (1.2 %). The remainder 308 cases (24.7 %) were operated under regional caudal anesthesia.

Warthin's tumor is a benign and slow growing tumor found exclusively in the parotid gland or the periparotid lymph nodes. It mostly affects males between the age of forty to seventy years and is closely related with smoking history. Between January 1981 and June 1996, 42 patients underwent surgical excision of Warthin's tumor of the parotid gland; which made up 10.6% of all parotid gland surgeries(398 cases) during the same period. Their ages ranged from 36 to 75 years with a mean age of 56 years. There were 33 male and 9 female patients with a 4.3 : 1 male to female ratio. The majority of the tumors were situated in the parotid tail whereas one was in the deep lobe. Bilateral simultaneous involvements of the parotid gland were found in 4 patients(9.5%) ; therefore total of 46 parotid glands were involved. Four(8.7%) of the 46 parotid glands had multifocal tumors ranginging from two to three lumps. Tumor sizes varied from 1.5 to 6.0cm with mean diameter of 3.lcm. Of the 42 patients, 26(61.9%) were diagnosed preoperatively or peroperatively by means of CT scans, ultrasound, 99m-Tc. scan, fine needle aspiration cytology or intraoperative frozen section biopsy. Of the 46 tumors, 30 underwent a superficial(n=29) or total(n=1) parotidectomy and for 16 cases with tumors suspected preoperatively or peroperatively of being single Warthin's tumor, only enucleation was performed. No cases of recurrence were identified during the follow up period regardless of type of operation performed, however the postoperative complication rate was much higher in the parotidectomy group(33.3%) than in the enucleation only group(12.5%). We feel that an enucleation procedure may be appropriate for the patients with single Warthin's tumor.
