It is well known that anatomic variations affecting the ostiomeatal unit (OMU) become one of the causes of mucosal abnormalities of paranasal sinuses (PNS). Findings of coronal plane CT scans of PNS were analyzed in 95 patients with sinusitis or sinusitis-like complaints. Anatomical variations were seen in 88 cases of 60 patients. Mucosal abnormalities were seen in 27 of 47 cases with concha bullosa, 23 of 37 cases with enlarged ethmoid bulla, 8 of 33 cases with Agger nasi, 20 of 26 cases with nasoseptal deviation, 7 of 8 cases with Haller cell, 3 of 6 cases with duoble middle turbinate, 4 of 6 cases with medially bent uncinate process, 1 cases with laterally bent uncinate process, and 33 of 40 cases with mixed variations. Mucosal abnormalities in cases with antomical variations were detected in 61 cases, including maxillary sinus(51 cases), anterior ethmoid sinus (26 cases), frontal sinus (4 cases), and mixed (32 cases). Mucosal abnormalities without anatomical variations were detected in 13 cases involving maxillary sinuses (7 cases), anterior ethmoid sinuses (5 cases), and frontal sinus(1 cases). In conclusion, as coronal plane CT scan has the capability of dolineating anatomical variations and mucosal abnormalities of PNS, it is considered useful in evaluating the treatment and prognosis of chronic or recurrent sinusitis.

PURPOSE: It is not easy to determine the cause of pulmonary consolidative lesion. Even without any definite mass, malignancy cannot be ruled out. And sometimes, it is difficult to differentiate tuberculosis from pneumonia. To differentiate malignant consolidative lesion from benign one, we studied patterns of air bronchogram, mucoid impaction, and computed tomographic anglogram etc. MATERIALS AND METHODS: Fifty seven cases of pulmonary consolidative lesions(23 cases of malignancy,34 cases of benign lesion) were retrospectively reviewed by three radiologists. RESULTS: Among the 28 cases which showed a little air bronchogram(less than 1/3 of the whole lesion in volumetric measure with the eye) 19 cases were malignancy and nine cases were benign lesions. All of the 12 cases which showed profound air bronchogram over 2/3 of the whole lesion were benign lesions. Bronchiectasis was detected in 31 cases(four of malignancy and 27 of benign lesions). Among the 20 cases which didn't show the mucoid impaction five cases were malignancy and 15 cases were benign lesions. Out of eight cases with mucoid impaction filling the long segments(branching tree shape), seven cases were malignancy and one case was benign lesion. So called CT anglogram was detected in nine cases of malignancy and two cases of benign lesions. All of nine cases of malignancy showed CT anglogram which was like arborizing tree. CONCLUSION: Scanty air bronchogram, profound arborizing mucoid impaction and/or CT angoigram within consolidative lesion could suggest malignancy.

Zonular traction tufts, which exist in 15% of normal population, do not cause retinal detachment by themselves but they can cause traction retinal detaehment when there is traction force added. It is thought that the possibility of development of retinal detaehment increases especially when zonular traetion tufts originate posterior to the vitreous base No case of traction retinal detachment caused by zonular traction tufts has been reported. Here, we report one suspected case of traction retinal detachment induced by zonular traction tufts and lens subluxation.

Appendicitis is one of the most common condition causing an acute abdomen in young adult population. Two-hundreds and fifty-nine cases of acute appendicitis provened by surgery and pathology during recent 2 years in Han-ll Hospital were studied and analyzed by preoperative plain abdominal X-ray. One case of barium enema was also done. The results were as follows; 1. Male fo female sex ration was 1:1. 2. In age distribution, the most commonage group was from two to four decade. (75.3%) 3. The most common clinical symptom was classical abdominal pain as86.5%. 4. The positive radiographic findings were obtained 75.7% of all cases. 5. Common radiographic findings as follows; 1) Reflex ileus on RLQ (73.7%) 2) Obliteration of Rt. psoas line (41.3%) 3) Scoliosis of lumbar spine(21.2%) 6. The most common site of appendix was retrocecal in position. (84.2%) 7. One case of appendicolith and one case of appendiceal diverticulum were demonstrated.

A study was conducted to present clinical and statistical analysis of pediatric patients admitted to Severance Hospital between Jan. 1966 and Dec. 1975. Remakable progress has been made in the field of pediatrics and pediatric surgery, particularly in physiology, anesthesiology and operative technique. However, the ultimate result hasn't been totally satisfactory, largely due to the lack of cognizance of early diagnosis and prompt treatment. Futhermore, most of the patients with associated abnormal conditions, such as congenital heart disease, other associated G.I. anomalies and chromosomal anomalies, require surgery, urgently A total of 250 cases were analyzed according to systems. The following results were obtained; 1. 1. In the sex ratio male to female was 6-7:1. 2. 2. The order of frequency of diseases was as follows; Congenital megacolon 50 cases(20.0%), Imperforated anus 45 cases (18.0%), Congenital hypertrophic pyloric stenosis 41 cases(16.4%), Congenital anomalies of intestine 29 cases (11.6%), Congenital anomalies of hepatobiliary system 25 cases(10.0%), Meckel's diverticulum 18 cases(7.2%), Situs inversus 11 cases (4.4%), Congenital diaphragmatic hernia 6cases(2.4%), Congenital anomalies of cecum 6 cases(2.4%), Esophageal diverticulum 6 cases (2.4%), Esophagealatresia 4 cases (1.6%), Congenital anomalies of pancreas 4 cases (1.6%), Patent omphalomessentric duct 2 cases (0.8%), Congenital intestinal perforation 2 cases (0.8%), and Congenital stomach perforation 1 cases (0.4%). 3. There was an overall mortality rate of 36 cases (18.9%), the causes of death were frequently associated with respiratory failure. 4. Associated congenital anomlies were found in 57 cases. They were G. I. Anomalies, congenital heart diseases, Down's syndrome and cleft palate. 5. Of significance was the fact in this study, congenital megacolon had the highest incidence which was in sharp contrast to accidental series in which congenital hypertrophic pyloric stenosis showed the peak incidence. These figures are very similar to that reported in various publications. This analysis suggest that a more keen understanding of neonatal physiology, embryology, surgical technique and improved post-operative care for anomalous patients, may certainly improve the ultimate outcome of corrective surgery.

In 1947, Liver described adenoid squamous cell carcinoma under the title of "adenoacanthoma of sweat gland". This tumor is not rare, but reported cases in literatures were relatively few. The tumor were frequently found in the sun-exposed skin; such as face, ear, neck etc.. The cases involving non-sun-exposed area, such as oral and labial mucosa, nosopharynx and vulva etc., were also reported. Therefore, the relation between the pathogenesis of adenoid squamous cell carcinoma and sun damage has been still debated. Immunohistochemical studies have recently suggested that this tumor is squamous cell carcinoma undergoing acantholysis. The authors experienced a case of adenoid squamous cell carcinoma of the vulva in a seventy-one year old female patient. She had suffered from itching sensation on vulva for 10 years, and palpable mass on vulva for 1 month. On gross examination, a pale gray pigmentation and erosion, was noted at the right labia major, the minor extending left labia major and minor. On microscopic examination, nests of atypical epithelial cells extending into the cornium showed an adenoid architecture. These were composed of a peripheral layers of cuboidal cell in a lacy pattern. And the glandular spaces contained dyskeratotic acantholytic tumor cells in central portion. Therefore we diagnosed this case as adenoid squamous cell carcinoma of the vulva.

This study was conducted to assess the risk of breast cancer by menstrual, reproductive, and lactational factors in Korean women. A total of 210 women living in Seoul aged 30 to 60 with a first diagnosis of breast cancer from 2 teaching hospitals in Seoul, and 249 control subjects, randomly selected from the female pensioners of Korean Medical Insurance Company living in Seoul were interviewed. There was a increasing risk with the decrease of age at menarche, and the adjusted odds ratio(OR) of early menarche(age 14 years or less compared with over 17 years) was 1.61(95% Confidence Interval [CI]: 0.95-2.74). The longer the interval between menarche and regular menstruation, the less risk of breast cancer(OR=0.31, 95% CI: 0.16-0.60). The effect of these menarche factors were more prominent among premenopausal women. The adjusted OR for the second category(25-29 years old) of the age at first pregnancy and the age at the first full term pregnancy, compared to the reference category( 24 years old), were 0.52(95% CI: 0.30-0.92) and 0.58(95% CI: 0.32-1.06), respectively. The late age at the last full term pregnancy had significant protective effect (OR=0.29, 95% CI: 0.10-0.88), and the age itself was important rather than the interval between the first and last full term pregnancy. Factors related to breast feeding(BF) had protective effect consistently. Among parous women, in referent to no BF, women with 1 year of BF had adjusted OR of 0.34(95% CI: 0.17-0.68), while those with 1-3 years of BF had 0.35(95% CI: 0.18-0.67), 3-5 years had 0.29(95% CI: 0.12-0.74), and more than 5 years had 0.06(95% CI: 0.02-0.17). Age at menarche with regular cycle have stronger effect on especially pre-menopausal breast cancer among Korean women. Recent increase in breast cancer incidence in Korea would be explained by delayed age at first pregnancy or delivery, earlier age at menarche and last delivery, and decrease in brest feeding.
