Nationwide incidence survey was conducted to estimate the annual incidence rates of colorectal cancer among Koreans between Jan 1, 1988 and Dec 31, 1989. The population of the incidence survey was the beneficiaries of Korea Medical Insurance Corporation (KMIC), which were about 4,500,000 persons. The medical records of patients with diagnosis of either ICD-9 153(colon cancer), 154(rectal caner), 197(secondary malignant neoplasm of digestive and respiratory system), or 211(benign neoplasm of digestive system) were abstracted for the period with the standard format. The diagnosis was confirmed by one oncologist through the review of these abstracts. The numerator of the rate was finally defined as the incident colorectal cancer cases diagnosed between July 1, 1988 and June 30, 1989. The crude annual incidence of colorectal cancer for men was 13.1 per 100,000 and 10.6 for women, which was still low when compared with those of Japan and China during the same period. Age-adjusted sex ratio was 1.2 for right-sided colon cancer and 1.9 for left-sided colon cancer. The excess of right colon cancer among postmenopausal women was remarkable, so further analytical approach would be needed to investigate which factors are related with this phenomenon.

From June 1979 to July 1988 for 9 years, total 440 cases of lung cancer[including biopsy and surgical specimen] of the Pusan Paik hospital were examined for the clinical and pathology study. The findings of the study are as follows; [1] The incidence of lung cancer started to increase from 1982, and it again remarkably increased since 1987. Such increase was solely brought by the increase of male lung cancer. Male and female ratio is 5.6: 1. [2] Histopathologically, the most prevalent type is squamous cell carcinoma[60.ado], and next are adenocarcinoma[15.6%] and small cell carcinoma[15.0%]. But in female alone, the most prevalent type is adenocarcinoma[40.3%], and next are squamous cell carcinoma[37.3%] and small cell carcinoma[11.9%]. [3] The absolute number of adenocarcinoma are approximately equally distributed among both sexes until 60 years of age. Above 61 years of age, mostly male was shown while female was not. Most probably, many female patient.- of that old age simply did not visit general hospitals for surgery in Korea. [4] Surgical treatment was performed in 8% of total cases of lung cancer. And most cases showed stage I progression of the cancer. Average size of the cancer was 5 cm in diameter in the operated 35 cases suggesting that the cancer could be detected more than 10 years ago before the time of surgery. [5] Lung cancer affected more in the right lung [right: left=1.6: 1], and each upper lobe of both lungs are affected about 1/4 of cases indicating that about 1/2 of all lung cancer develop from the upper lobes. [6] There are more nonsmokers[67.6%] among the lung cancer patients[male 64.6%, female 82.1%]. Probably, this will mean that there are other potent carcinogenic agents in our environment like automobile exhaust beside tobacco smoke. For the past history of lung disease other than cancer, tuberculosis is the most prevalent disease[16.1%, male 17.4%, female 9.0%]. Most of them is probably not related etiologically though this possibility is not completely denied.

Background: Neck pain can be caused by any structure in the neck, such as intervertebral discs, ligaments, muscles, facet joints, dura mater, and nerve roots. The hyoid bone is a structure that is also related to head and neck posture, neck movement and pain, but there are no studies on hyoid deviation, neck pain, and range of motion (ROM). Objects: The purpose of this study was to investigate the effect of fascia relaxation and mobilization of the hyoid bone on the ROM, pain, and lateral deviation of the hyoid bone. Methods: Twenty-five patients with neck pain identified by the lateral motion test (10 males [35.13 ± 7.67 years, 172.69 ± 3.90 cm, 78.77 ± 6.96 kg] and 15 females [35.13 ± 10.05 years, 161.11 ± 4.09 cm, 52.59 ± 2.98 kg]) was chosen randomly. Baseline values for pain, neck ROM, and lateral deviation in the hyoid bone were recorded using a visual analogue scale (VAS), goniometer, and tape measure. Then, each patient was treated with hyoid fascia relaxation and mobilization, and all results were recorded after intervention. Comparison of the results before and after intervention was analyzed using paird t-test (p < 0.05). Results: Right rotation, extension, VAS, and rotational asymmetry statistically significant differences (p < 0.05). Right rotation and extension increased ROM, rotational asymmetry ratio and VAS decreased. However, there was no significant difference in flexion, left rotation, center point (p > 0.05). Conclusion: Fascia relaxation and hyoid mobilization could improve the ROM of cervical extension, asymmetry of the cervical rotation and neck pain.

Cleft lip is one of the most common congenital deformities in craniofacial region. Despite the many reports on the outcome of various surgical techniques from individual medical centers, the evaluation of the outcome is based on the subjective observation because of lack of the objective evaluation system. Therefore, a new technique of objective and scientific evaluation for the nasal deformity of secondary cleft lip and nose deformity is critical to improve the management of the cleft patients including the decision of optimal age of operation and surgical technique as veil as evaluation of the outcome. In this study, a new method was proposed to evaluate the nasal deformity using nostril angle, distance, and area of patient images. The images were also evaluated by three expert plastic surgeons, and put into scale of 5 percentile. Measurement results were compared between the each category and the surgeon's evaluation, and coefficients of each category were statistically tested. As a result, The normalized overlap area of right and left nostrils and distance ratio between two centers of nostrils showed high coefficient with evaluations of plastic surgeons.

Hypertrophic pachymeningitis is an uncommon disorder that causes a localized or diffuse thickening of the dura mater. Recently, the possibility that IgG4-related sclerosing disease may underlie some cases of intracranial hypertrophic pachymeningitis has been suggested. We herein report the tenth case of IgG4-related intracranial hypertrophic pachymeningitis and review the previous literature. A 45-year-old male presented with left-sided focal seizures with generalization. Magnetic resonance imaging (MRI) revealed a diffuse thickening and enhancement of the right convexity dura matter and falx with focal nodularity. The surgically resected specimens exhibited the proliferation of fibroblast-like spindle cells and an infiltration of mononuclear cells, including predominantly plasma cells. The ratio of IgG4-positive plasma cells to the overall IgG-positive cells was 45% in the area containing the highest infiltration of plasma cells. On the basis of the above findings, IgG4-related sclerosing disease arising from the dura mater was suspected. IgG4-related sclerosing disease should be added to the pachymeningitis spectrum.

We have observed 360 cases of spontaneous pneumothorax from January 1980 to May 1991 at the department of Thoracic and Cardiovascular Surgery, Chosun University Hospital. Males occupied 266 cases[73.9%] and females 94 cases[26.1%], and its ratio was 2.8: l. The age of patients ranged from neonate[5 days] to 84 years old. The site of pneumothorax was right in 50.3%, left in 43.3% and bilateral in 6.4%a. The clinical symptoms were frequently dyspnea, chest pain and coughing. The associated pulmonary lesions were shown pulmonary tuberculosis in 199 cases[55.3%], bullae in 54, pulmonary emphysema in 31, COPD in 17, pneumonia in 6, lung cancer in 5, paragonimiasis in 5, catamenial pneumothorax in 3 and unknown underlying pathology in 39 cases. The results of surgical management of spontaneous pneumothorax are followings: 288 out of 360 cases[80.0%] were cured by closed thoracotomy, 53 cases[14.8%] were cured by open thoracotomy. Open thoracotomy was the most effective procedure in persistent air leakage, recurrent pneumothorax, visible bleb or bullae on the chest X-ray, associated lesion, bilateral simultaneous pneumothorax, parenchymal incomplete lung expansion and bleeding after closed thoracotomy. The incidence of complication was developed in 10. ado and recurrent rate was seen in 10.6%. There was no operative death.

Objectives : The limited number of studies to date have mainly focused on the effect of obesity on the characteristics of plantar foot pressures. This study is designed to find the correlation between plantar pressure and obese index. Methods : This study assessed the body composition of 30 obese women using bioelectrical impidence analysis and Gaitview AFA-50. The static and dynamic plantar pressure was determined from electronic footprints captured using a capacitive pressure distribution platform during standing and walking. The data were analysed by independent t-test and Pearson Correlation. Results : Positive correlations were noted between body weight, body mass index(BMI), waist circumference(WC), waist-hip ratio(WHR) and difference of fore and rear plantar pressure. And negative correlations were noted between body weight, BMI, WC, WHR and difference of left and right plantar pressure. Conclusions : The findings of this pilot study suggest that body composition influences the waight distribution in overweight and obese subjects.

From March, 1985, to June, 1993, 244 patients with 345 episodes of spontaneous pneumothorax treated at Koryo General Hospital were reviewed. Most of the patients were male, and the ratio of male to female was 8:1. The average age of the patients with spontaneous pneumothorax was 32.8 years old. The site of pneumothorax was revealed left side in 53.3%, right side in 42.6%, and bilateral in 4.1%. The cause of pneumothorax were shown primary spontaneous pneumothorax in 73.4%, and secondary spontaneous pneumothorax in 26.6%. The underlying pathologic lesion in secondary spontaneous pneumothorax showed pulmonary tuberculosis in 56patients[86.1%], COPD in 4patients[6.2%], bronchial asthma in 2patients[3.1%], lung cancer in 2patients[3.1%], and pneumoconiosis in a patient[1.5%]. The usual clinical symptomes were dyspnea, chest pain and chest discomfort. Recurrence rate was as follow; 2nd episode 33.6%, 3rd episode in 26.8%, and above in 4th episode in 18.2%. All the patient of pneumothorax was treated as following; Closed thoracostomy tube drainage in 127patients, bullectomy in 88patients, lobectomy in 5patients, wedge resection in 2patients, conservative treatment with oxygen therapy in 21patients, and video assisted thoracoscopic bullectomy in a patient. The course of treatment of all of the patients were smooth and uneventful.

Purpose: This study classified alveolar arch forms and evaluated differences in alveolar bone thickness among arch forms in the anterior esthetic region using cone-beam computed tomography (CBCT) images. Materials and Methods: Axial views of 113 CBCT images were assessed at the level of 3 mm below the cementoenamel junction (CEJ) of the right and left canines. The root center points of teeth in the anterior esthetic region were used as reference points. Arch forms were classified according to their transverse dimensions and the intercanine width-to-depth ratio. The buccolingual alveolar bone thickness of each tooth was measured at 3 mm below the CEJ and at the mid-root level. Differences in the mean thicknesses among arch forms were analyzed. Results: Anterior maxillary arches could be classified as long narrow, short medium, long medium, and long wide arches. Significant differences in buccolingual alveolar bone thickness among the arch groups were found at both levels. The long wide arches presented the greatest bone thickness, followed by the long medium arches, while the long narrow and short medium arches were the thinnest. Conclusion: Arch forms were classified as long narrow, short medium, long medium, and long wide. The buccolingual alveolar bone thickness exhibited significant differences among the arch forms.
