The coracoclavicular joint is a rare genetical anatomic variants. The joint occurs at the junction of a bony projection extending inferiorly form the outer third of the clavicle at the site of the conoid tubercle and a bony projection extending superiorly form the coracoid process of the scapula. In our study we reviewed the radiological incidence of the coracoclavicular joint in Korean adults. The materials consist of 4,625 routine chest films, 9,250 sides. Sex distribution were 3,000 males and 1,625 females. The authors observed coracoclavicular joint on 17 persons (0.37%) and 25 sides (0.26%) and among them, 8 persons (47%) were bilateral and in 9 (53%) it was unilateral. The joint when unilateral occures frequently on left side, and there was no significant sex difference. There were statistically significant differences in the incidence of coracoclavicular joints among Korean, Japanese and Chinese.

One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed CP as determined by an enzyme-linked immunosorbent assay, indicating that compact morphology does not exclude encapsulation. The majority of the strains (11/12) showed autoagglutination in the salt aggregation test. The serotype 336 accounted for 46.7% of the isolates followed by serotype 5 (12.1%) and serotype 8 (12.1%). Particularly, twenty-six (24.3%) isolates reacted with two serotypes; 7 for type 8/336 and 19 for type 5/336. Five isolates (4.7%) were nontypeable with monoclonal antibodies specific for CP serotype 5, 8, or 336. The CP concentration in culture supernatants varied with the serotypes, and the total amount of CP produced by cells grown in a liquid medium was much less than that produced by cells grown on a solid medium. The Western blotting indicated that the CP bands of S. aureus serotype 5 and 8 were ranged in the molecular mass of 58-84 kilodalton (kDa), with additional bands in the region of approximately >or= 48 or Agglutination Tests ; Animals ; Bacterial Vaccines/administration & dosage ; Cattle ; Cattle Diseases/immunology/microbiology ; Female ; Mastitis, Bovine/*microbiology ; Polysaccharides, Bacterial/*classification/isolation & purification ; Serotyping/methods/veterinary ; Staphylococcal Infections/immunology/*veterinary ; Staphylococcus aureus/*classification/*immunology/isolation & purification

Paget's disease is classified, according to location, as mammary or extramammary disease. Extramammary Paget's disease especially in the vulva is extremely rare. Several hundred cases have been described worldwide. Patients with Paget's disease of the vulva are usually white and postmenopausal. The cause of which remains elusive. A case of vulva Paget's disease is presented with brief review of literature.

The trachea is a cartilagenous and membranous tubular midline structure with parallel walls. Tracheal deviation may be caused either by traction toward the diseased hemithorax or by compression toward the normal side. Unless an obvious mass is observed radiographically, occasionally it can be difficult to decide whether the trachea has been pushed or pulled from its normal position in the mediastinum. We studied the differences between tracheal deviation patterns in 23 patients with fibroatelectatic pulmonary tuberculosis and 35 patients with elongated and dilated aortas. In cases of retraction of the trachea by fibroatelectatic pulmonary tuberculosis, the diameter of the deviated segment was greater than that of the normal segment and deviation of the wall adjacent to the fibroatelectasis from its normal position was greater than that of the opposite wall. In cases of compression of the trachea by the elongated and dilated aorta, the diameter of the diviated segment was smaller than that of the normal segment and deviation of the wall adjacent to the aortic arch from its normal position was greater than that of the opposite wall. We conclude that these differences between tracheal deviation patterns are useful signs for discriminating retraction from compression. Thus when the trachea is retracted, the deviation of the juxtalesional wall is greater than that of the lesion-free wall, and vice versa.

Oral cholecystography is one of the most relible and widely used x-ray examination which enables us to observe not only morphological features of the gallbladder (GB) but also its functioning state. It was disclosed that functional evaluation of the GB is mandatory to recognize such kinetic disorders of the viscus as acalculous cholecystitis or dyskinesia. For the purpose of functional evaluation, fat meal has been used traditionally. Recently, cholecystokinin(CCK) and ceruletide were introduced into clinical diagnosis of the GB, the usefulness of which we have confirmed. In the present study we have made an attempt at improving cholecystagogic effect of conventional fat meals(FM) such as whole mild and egg yolk by changing the posture of the examined from sitting up to right decubitus position after the ingestion of fat meal. The hypothesis involved in this study is that the presence of quantitatively more fat meal in the duodenum per unit time may result in more effective cholecystagogic action and such a setting would be created by enhancement of pyloric passage of fat meal by decubitus posturing. Clinical materials consisted of 280 normal oral GB series (136 males and 144 females) andthey were divided into 4 equally numbered groups of mild sitting and mild decubitus and egg sitting and eggdecubitus. Upon confirming satisfactory opacification of the GB 11 hours after the ingestion of 3g of sodiumipodate or iopanoci acid either 2 pieces of medium sized hen's egg yolk were given. The xaminess were then allowed either sitting up comfortably on a bench or lying down on the right flank on a couch. After the ingestion of fat mean, x ray was taken at the end of 30 minutes in all but the mild decubitus group in which x rays were taken serially at the end of 5, 15, 30 and 60 minutes. The frontal area of each opacified GB was measured by using aplanimeter and the contraction rate before and after fat meal stimulation was calculated by the following equation and delineation of the biliary tree was analyzed in each group. Contraction rate (%) = (1

Visualization of falx cerebri on non-enhanced CT of children with severe head injuries (the falx sign) has been regarded as an evidence of subarachnoid hemorrhage. On the contrary, other authors have reported reverse results. To evaluate clinical significance of the falx sign, authors studied frequency of visualization and CT number of falx cerebri and dural sinuses in 65 children with head injury and 65 children without head injury examined by cranial CT at the Dep. of Radiology, St. Paul's Hospital, Catholic Medical College from March to Sept. 1981. All patients with head trauma were studied within 1 week of the traumatic event. Visualization of falx cerebri was observed at slice in the region of lateral ventricle and slice near to vertex respectively. On the slice in the region of lateral ventricle, falx cerebri was identified in 82% of all of the children examined, of which 92%showed partial visualization of falx cerebri and remaining 8% totally. On the slice near to vertex, falx cerebri was identified in 92% of all the children examined, of which 38% showed partial visualization of falx cerebri and remaining 62% totally. In head trauma group, frequency of visualization of falx cerebri was 78% on the slice in the region of lateral ventricle and 89% on the slice near to vertex; in non-traumatic group, frequency of visualization of falx cerebri was 86% and 94% respectively. The highest numerical value of the falx densities averaged 47 Hounflieds (range, 32-63) in non-traumataic group, averaged 49 Housfields (range, 32-69) in head trauma group. All or a portion of the superior sagittal sinus was visualized in 59% of all of the cases studied, 50% in head trauma group, and 69% in nontraumatic group. The straight sinus was identified in 45% of all of the cases studied, 39% in head trauma group, and 51% in non-traumatic group. In conclusion, there was no distinction between head trauma and non-traumatic group in visualization of falx cerebri and dural sinuses, and we could frequently identify the falx density in normal. Also we could find that frequency for visualization of falx cerebri and drual sinuses increased as the age increased.

BACKGROUND: There has been reports which suggest that non-specific symptom of patients with mitral valve prolapse is associated with autonomic dysfunction. METHODS: To assess autonomic dysfunction of patients, we examined five cardiovascular reflex tests in 25 asymptomatic MVP patients(identified as MVP group), 25 symptomatic MVP patients(identified as MVP syndrome group) and 25 control group. RESULTS: In the five cardiovascular autonomic function tests, abnormalities of Valsalva ratio were detected in 1(4%) control group, 7(28%) MVP group, 9(36%) MVP syndrome group, heart rate response to deep breathing in 0(0%), 2(8%), 4(16%) respectively, immediate heart rate response to standing in 0(0%), 2(7.4%), 2(8%) respectively and in postural hypotension, there were no abnormal group. Abnormalities of blood pressure response to sustained handgrip were only detected in 2(8%) MVP syndrom group. According to the five categories of cardiovascular autonomic functon tests, normal in 24(96%) and early damage in 1(4%) were detected in control group. In the MVP group, normal 17(68%), early damage 6(24%) and definite damage 2(8%) were noted. In the MVP syndrome group, normal 9(36%), early damage 13(52%), definite damage 1(4%) and combined damage 2(8%) were detected. In case of heart rate response to deep breathing, we found significant differences between control and MVP syndrome group(p=0.043), and between MVP and MVP syndrome group(p=0.0043). In case of heart rate response to standing, between control and MVP syndrome group(p=0.0009), between MVP and MVP syndrome group(p=0.001), the differences were noted. In case of blood pressure response to standing, between control group and MVP group(p=0.0019), between MVP and MVP syndrome group(p=0.0075), we found significant differences. Resulting from our study, heart rate response to deep breathing and standing, blood pressure response to standing were of considerable value in assessing the autonomic dysfunction of patients with mitral valve proapse. CONCLUSION: We found autonomic dysfunction in addition to increased autonomic tone and responsiveness which have been already known previously in mitral valve prolapse. And autonomic dysfunction was more severe in symptomatic patients with mitral valve prolapse than asymptomatic ones.

Thymic size can be affected by both exogenous and endogenous glucocorticoids. Development of the respiratory distress syndrom (RDS) is influenced by adernal cortical function. thus, thymic size in RDS is considered to been larged due to decreased adrenal cortical function. To find whether the presence of RDS correlates with thethymus, the size and shape of the thymus were evaluated in the radiographs of premature infants with RDS, without RDS(control prematurity) and normal infants. The subjects were consisted of chest films of Korean premature infants, 120 with RDS, 60 without RDS, and 60 of normal infants taken at the Departement of Radiology, Our Lady of Mercy Hospital during the period of 62 months since January 1978. Relative size of the thymus was determined bycardiothymic/thoracic ratio(CT/T ratio). Grading and locaiton of the thymic prominence as well as incidence of the shape were examined. And all the relations among the radiographs of RDS, control prematurity and normal infants were analyzed. The results were as follows; 1. The CT/T ratio of premature infants with RDS was significantly greater than that of control prematurity and normal infants (P<0.01). 2. The incidence of bilateral thymicprominence was more frequent in premature infants with RDS than in control prematurity and normal infants(P<0.05).3. The frequency of thymic prominence was greater in the right than left side in all the three groups (P<0.05). 4.As in the shape of the thymus, a rounded type was most frequent, and a triangular type was least frequent in allthe three groups. 5. Incedence of RDS was very low(9.8%) when the CT/T ratio is below 0.3 and it was very high(90.9%) when the CT/T ratio is above 0.49.

BACKGROUND: Mitral stenosis is charcterized by decrease in mitral valve area anatomically and increase in transmitral pressure gradient hemodynamically. And these changes have been used to quantify the severity of mitral stenosis clinically. To evaluate the clinical usefulness of mitral valve resistance as a hemodynamic parameter in patients with mitral stenosis, we compared the mitral valve resistance to the clinical status of the patient with mitral stenosis, the other hemodynamic parameters and static parameter. METHODS: We analyzed and reviewed the data obtained from the consecutive 27 patients with mitral stenosis(7 male, 20 female : mean age 38+/-9 years) who had been underwent percutaneous mitral valvuloplasty(PMV). RESULTS: Befor PMV, the mitral valve resistance was significantly correlated with exercise capacity on treadmill test(r=-0.37, p<0.05), mitral valve area(r=-0.72, p<0.01), transmitral mean pressure gradient(r=0.83, p<0.01),not with cardiac output, mixed venous oxygen saturation. After PMV, the mitral valve resistance was significantly correlated with mitral valve area (r=-0.72, p<0.01), transmitral mean pressure gradient(r=0.90, p<0.01).According to the results summerizing and comparing the values of before and after percutaneous mitral valvuloplasty, the mitral valve resistance had good relationship with preexisting paramerters of severity such as mitral valve area(r=-0.82, p<0.01), transmitral mean pressure gradient (r=0.92, p<0.01). CONCLUSION: This results indicate that the mitral valve resistance is a useful hemodynamic parameter in patients with mitral valve stenosis and reflects the exercise capacity during the treadmill test which was the objective parameter of practical and clinical status of the patient well than the other hemodynamic parameters in case of remarkably reduced transmitral valve blood flow due to severe mitral valve stenosis, because the degree of change in the mitral valve resistance in relagion to the degree of change in transmitral valve blood flow is relatively more constant than the other hemodynamic parameters.

PURPOSE: Testicular microlithiasis (TM) is an uncommon benign condition characterized by calcium deposits in the lumen of the seminiferous tubules. It may be associated with testicular malignancies and infertility. MATERIALS AND METHODS: We performed a retrospective review of clinical charts and scrotal ultrasound findings of 18 patients who were found to have TM. Scrotal ultrasound scans were performed using 5- to 10-mHz high-resolution transducers. The indication for ultrasonography was an abnormal scrotal examination. RESULTS: The mean age at presentation was 39.9 years (range 14 to 70 years). Most (15; 83.3%) of the patients had bilateral TM. There were no differences in the sonographic patterns and appearance according to patient age. A third of the patients (7; 38.9%) had benign epididymal lesions. Two with bilateral TM had unilateral testicular malignancy. A varicocele was identified in two men, who demonstrated normal semen parameters. A 16-year-old boy showed no interval sonographic changes at 1-year follow-up. CONCLUSIONS: Testicular microlithiasis usually affects both testes. The association between TM and progres sion of cancer is unclear.
