Background: Intralobar and extralobar pulmonary sequestrations have been considered as congenital lesions that occur at different stages of embryonic life. However, most cases of intralobar pulmonary sequestration (IPS) seem to have an acquired origin, as they are absent in infants and associated anomalies are relatively, uncommon among them. Material and Method: The cases of 25 patients who were diagnosed as IPS after surgical resection from December, 1985 to July, 2002 were included in this study. The medical records wire retrospectively reviewed and the clinical characteristics were age at operation; gender; symptoms at presentation; presence of congenital anomalies; combined diseases; preoperative studies and diagnosis; location of the lesion; method of surgical resection; origin, size and numbers of aberrant artery; histopathological findings; and postoperative complications. Result: There were 17 (68%) female patients and 8 (32%) male patients, their ages ranged from 1 to 57 and mean value was 23 years old. Though 14 patients (56%) complained of respiratory symptoms such as pneumonia and recurrent respiratory infections, a large number of patients (44%) were asymptomatic or had chest pain only when the lesion was discovered. Only 8 patients (32%) were diagnosed as pulmonary sequestration preoperatively and 8 (32%) were suspected as mediastinal or lung tumor, 5 (20%) were congenital or acquired cystic lung disease, and 4 (16%) were lung abscess or bronchiectasis, respectively. The majority of aberrant arteries (86.4%) confirmed during the operation were originated from thoracic aorta and 2 were thoracic and abdominal aorta, 1 was abdominal aorta, respectively. The younger patients (less than 10 years old) had more other congenital anomalies (30% vs 6.7%) but the proportion of congenital IPS was not significantly different (10% vs 6.7%, p>0.05) compared with elder patients. Histopathologically, almost all lesions showed chronic inflammation, cystic changes and similar pleural adhesions regardless of age. Conclusion: The large portion of the patients with IPS (44%) was clinically asymptomatic or presented non-respiratory symptoms at diagnosis and likely to be diagnosed as mediastinal or lung tumor especially in elder patients. Though the younger patients had more other congenital anomalies, most cases of IPS proved to be acquired lesions in terms of the histopathlogical findings and the proportion of congenital evidences.

Primary lung cancer has recently increased progressively in its incidence in Korea. It is clearly evident that surgical resection offers the best offortunity for cure of non-small cell carcinoma. This study was designed to analyse the clinical data of 100 primary non-small cell carcinoma patients who underwent lung resection surgery from January 1992 to July 1995 at the department of Thoracic and Cardiovascular Sugery, Kyungpook National University Hospital. There were 86 males and 14 females(6:1). In the age distribution, the peak incidence was recorded in the seventh decade(43%). The methods of tissue diagnosis were bronchoscopic biopsy in 53 patients(50.5%), percutaneous needle aspiration in 17 patients(16.2%), transbronchial lung biopsy in 11 patients(10.5%), mediastinoscopic biopsy in 2 patients (1.9%), sputum cytology in 2 patients(1.9%), and thoracotomy in 20 patients(19.0%). Fifty-five lobectomies, 22 pneumonectomies, 15 bilobectomies, 2 segmentectomies, 4 sleeve lobectomies, a sleeve pneumonectomy, and a wedge pneumonectomy were performed. Operative mortality occured in 4 cases(sepsis in 2 cases, respiratory failure in 1 case, and acute myocardiac infarction in 1 case). The histologic types of tumor were 67 squamous cell carcinomas, 26 adenocarcinomas, 6 large cell carcinomas, and an adenosquamous cell carcinoma. Eighteen patients with N2 mediastinal lymph node metastases had 8 squamous cell carcinomas(11.9%), 9 adenocarcinomas(34.6%), and a large cell carcinoma(16.7%). The primary tumors in these patients were in the right upper lobe in 4 patients, the right middle and lower lobe in 9 patients, the left upper lobe in 3 patients, and the left lower lobe in 2 patients. With regard to pathologic stages, 45 patients had stage I disease; 13 patients, stage II; 36 patients, stage IIIa; 5 patients, stage IIIb; and 1 patient, stage IV. The overall actuarial survival rate was 77.5% at 12 months, 56.1% at 24 months and 43.7% at 43 months. The actuarial survival rates at 43 months were 81.3% in Stage I, 20.8% in Stage II, 27.9% in Stage IIIa, 25.0% in Stage IIIb and 33.3% in Stage IV. These facts suggest that early detection and surgical resection are recommended for favorable postoperative survival in non-small cell lung cancer.

This study examined the actual state and future improvement of food allergies in adolescents and adults in order to prevent damage. In this survey, proportions of females, people in their 40s, college graduates, and office workers and housewives with allergies were higher than other groups. Exactly 41.1% of participants responded that they had experienced food allergies while 58.9% responded that they had not. According to their responses, the most common food allergy symptom involved the skin while whole-body allergic reactions were rare. Most respondents answered that frequency of their food allergies was two or three times. There was a variety of allergenic foods, including fast food, eggs, mackerel and milk, and instant food was ranked as the most allergenic food. Therefore, in order to protect consumers from damage caused by food allergens, the food allergen labeling system must be improved. A better food allergen labeling system should be implemented to avoid potential risks of allergic reactions and ensure national food safety.

The Background and Purpose It is done the study on the public health care of oriental medicine and improvement of its system recently, I think that these effect a good health care for a people through the public health care of oriental medicine. Since Woosuk university and Chonju-Wansan health center had taken upon the oriental medicine service in the health center in 1995, we have public favor from the local population. So in other to a study on the clinical statistics of oriental medicine service in the health center, I investigated general character, style of diseases, effect of treatments and the like for a paitents received oriental medicine treatments in there. Objective and Methods This study researched into clinical statistics for paitents received oriental medicine treatments in the Chonju-Wansan health center during one year period from January 4 1996 to December 26 1996. The number of object was 238 case of 234 persons. Results and Conclusions Analyzing these 234 persons, the proportion of males to females was 1 to 6.8. As for the distribution of age, the ages of 61 to 70 occupied 34.62 per cent in the ages of 51 to 90 occupied 88.89 per cent in the whole paitons. Therefor female was very highly more than male and paitents were for the most part, old ages(51years old and over). Musculoskeletal system and connective tissue disease of 238 case occupied 82.77 per cent. were the greatest proportion. At the duration of disease, 1 year to 5 years occupied 32.35 per cent, was the highest The grade Ⅲ was the most of the sign of paitents at first visit, it occupied 55.88 per cent. The good(++) and over effect of treatments occupied 62.18 per cent, the fair(+) and over effect of treatments occupied 78.99 per cent. As for the duration of treatment, the case of 2 times to 5 times visit occupied 34.03 per cent, was the highest. And the case of 2 times to 10 times visit was 4 times as good effect as the case of only one visit. By medication of treatment, O-Juk-San(五積散) occupied 32.21 per cent, was the greatest proportion, and Pal-Mj-Hoan(八味丸) occupied the second greatest proportion. Therefor the most of paitents had the chronic diseases and was diagnosed Sin-Yang-He(腎陽虛). The average 22.58 persons received acupuctural treatment a day, the average 0.58 persons received the moxibustion a day, the average 2.28 persons received venesection (bloodletting) a day. And others treatment performed physical therapy and the like. The case received treatment of the oriental and western medicine at the same time. marked 21 persons among 30 persons and had a good effect by 70 per cent. The average 26.95 persons received treatment of oriental medicine a day, the average 3.9 persons received the first medical examination a day.

Purpose : To evaluate the clinical features and characteristics of childhood periodic syndromes (CPS) in Korea using the new criteria of the International Classification of Headache Disorders (ICHD)-II. Methods : The study was conducted at pediatric neurology clinics of five urban tertiary-care medical centers in Korea from January 2006 to December 2007. Patients (44 consecutive children and adolescents) were divided into three groups (cyclic vomiting syndrome [CVS], abdominal migraine [AM], and benign paroxysmal vertigo of childhood [BPVC]) by recurrent paroxysmal episodes of vomiting, abdominal pain, dizziness, and/or vertigo using the ICHD-II criteria and their characteristics were compared. Results : Totally, 16 boys (36.4%) and 28 girls (63.6%) were examined (aged 4-18 yr), with 20 CVS (45.5%), 8 AM (18.2%), and 16 BPVC (36.4%) patients. The mean age at symptom onset was $6.3{\pm}3.6$ yr, $8.5{\pm}2.7$ yr, and $8.5{\pm}2.9$ yr in the CVS, AM, and BPVC groups, respectively, showing that symptoms appeared earliest in the CVS group. The mean age at diagnosis was $8.0{\pm}3.4$ yr, $10.5{\pm}2.6$ yr, and $10.1{\pm}3.2$ yr the CVS, AM, and BPVC groups, respectively. Of the 44 patients, 17 (38.6%) had a history of recurrent headaches and 11 (25.0%) showed typical symptoms of migraine headache, with 5 CVS (25.0%), 2 AM (25.0%), and 4 BPVC (25.0%) patients. Family history of migraine was found in 9 patients (20.4%): 4 in the CVS group (20.0%), 2 in the AM group (25.0%), and 3 in the BPVC group (18.8%). Conclusion : The significant time lag between the age at symptom onset and final diagnosis possibly indicates poor knowledge of CPS among pediatric practitioners, especially in Korea. A high index of suspicion may be the first step toward caring for these patients. Furthermore, a population-based longitudinal study is necessary to determine the incidence and natural course of these syndromes.

Background: Miliary tuberculosis almost always results from the discharge of infected caseous material into the blood stream, usually from a well hidden lymph node in the presentation of this disease in the past four decades, and although it is seen less frequent1y today than previously, its presentation and manifestation may require greater suspicion and diligence by the physician. We investigated the clinical characteristics, predisposing factors and accompanying diseases of miliary tuberculosis and tried to acquire the early diagnosis and treatment of this disease. Methods: A retrospective clinical study was done on 40 cases of miliary tuberculosis admitted to Hanyang University Hospital from Mar. 1989 to Dec.1992. The study investigated age and sex distribution, seasonal distribution, duration of symptoms before admission, pre-disposing factors, clinical symptoms, biochemical findings, chest X-ray findings, extrapulmonary tuberculosis associated with miliary tuberculosis, prognosis and mortality rate. Results: 1) The patients were most common in the age group between 20 and 29(23%) and the ratio of male to female was 1.4:1(male 23 : female 17). 2) Sputum smears for tubercle bacilli were positive in 5 cases(13%). 3) The most common clinical symptoms were fever with chilling(47.5%), coughing(47.5%), second most common symptom was dyspnea(32.5%), and the physical findings on admission were tachycardia(30%), weight loss(27.5%), meningeal signs(17.5%) in order. 4) The predisposing factors were heavy alcohol drinking(6 cases), steroid use(3 cases), pregnancy(2 cases) etc. 5) The chest X-ray findings on admission were miliary shadow only(40%), in addition pneumonic infiltration, pleurisy, and calcification in order. 6) The extrapulmonary tuberculosis associated with miliary tuberculosis were tuberculous meningitis(30%), bone and joint tuberculosis(17.5%), intestinal tuberculosis(15%) in order. 7) Biochemical findings were increased SGOT/SGPT(32.5%), increased alkaline phosphatase(32.5%), hypoalbuminemia(15%), hyponatremia(15%) etc. 8) About 4-6 weeks later after treatment(INH, RFP, PZA, EMB), 26 cases(65%) were improved on clinical symptoms or chest X-ray, 12 cases(30%) were stationary or aggravated, and 2 cases(5%) were died. Conclusion: For the early diagnosis and treatment of miliary tuberculosis, we must see its presentation and manifestation with greater interest and suspicion and investigate its predisposing factors and accompanying diseases.

Osteoarthritis (OA), the most common form of arthritis, is a result of both mechanical and biological events that destabilize the normal coupling of degradation and synthesis of articular cartilage chondrocytes and extracelluar matrix, and subchondral bone. Although it is likely that the molecular basis of pathogenesis is similar to that of other joints, additional study of the temporomandibular joint (TMJ) is required due to its unique structure and function. This study was carried out to evaluate the epidemiologic characteristics of TMJ osteoarthritis. The purpose of this study was to investigate the prevalence of TMJ OA in Patients with temporomandibular disorders (1405 men and 2922 women whose mean age was $30.2\; {\pm}\; 15.4$ and $33.1\;{\pm}\;15.2$ years, respectively) who had visited the TMJ and Orofacial Pain Clinic of Seoul National University Dental Hospital in 2007. Orthopantomograms, TMJ tomograms and transcranial radiographs were used to evaluate degenerative change of the mandibular condyle. The obtained results were as follows: 1. Degenerative change of the mandibular condyle was observed in 883 (20.4%) of 4327 subjects. The prevalence was significantly higher in women (706 patients, 24.1%) than in men (177 patients, 12.6%), and this significant difference between genders was observed in all age groups. 2. The prevalence of degenerative change of the mandibular condyle in TMD patients showed a gentle increase along with age. Such increase was statistically significant in women (P < 0.001), but not in men. 3. Sclerosis was observed the most frequently in all age groups and the mean age of the patients with osteophyte was the highest among four types of degenerative change. 4. Although men showed degenerative change in the left side more often and women showed degenerative change more frequently in both sides, the difference of distribution in sides between genders was not significant. In conclusion, the prevalence of degenerative change of the mandibular condyle in TMD patients is higher in women than in men, and increases steadily with aging, but not as dramatically as in other joints that show a steep increase in prevalence around the age of 45 years. It can be suggested that the epidemiologic characteristic of OA of the TMJ differs from those of other joints, and that a more extensive study based on the general population is necessary.
