RESUMO
Brunner's gland hyperplasia, also known as Brunner's gland adenoma, polypoid hamartoma, or Brunneroma, is a rare proliferative lesion arising from the Brunner's glands of the duodenum. These lesions have been described previously as benign, with no malignant potential. We report a case of Brunner's gland hyperplasia in the duodenum that was discovered incidentally during the endoscopic evaluation of anal bleeding. Histopathological examination of this Brunner's gland hyperplasia revealed well-marked, low-grade dysplasia. This case suggests a dysplastic stage with malignant potential in the natural history of Brunner's gland hyperplasia.

A new surgical approach to the area of the infratemporal fossa and parapharyngeal space is described. This approach results in a wide-field exposure of the infratemporal fossa, pterygomaxillary space and parapharyngeal space. We used two osteotomies on the patient's mandible and temporary resection of zygomatic arch for superior margin of tumor. Lower lip splitting was not needed because the incision was started in the frontal scalp, curved in front of and below the external auditary canal, and extended anteriorly to the greater horn of hyoid bone on the neck along a skin crease. We had good results without sacrifice of the facial nerve, mandibular function and sensory supply of the face and oral cavity.

OBJECTIVES: Spontaneous bacterial peritonitis (SBP) is a frequent and severe complication of cirrhosis. In the most recently published studies, the prevalence of SBP among hospitalized cirrhotics with ascites has been estimated to be around 10-15%, the mortality rate related to this complication being more than 50%. SBP is thought to appear as a consequence of the impaired defensive mechanisms against infection present in cirrhotic patients, such as depressed reticuloendothelial system phagocytic activity, impaired leukocyte function, reduced serum compliment levels, and low antibacterial activity of ascitic fluid. It has proposed that ascitic fluid opsonin capacity is directly correlated to ascitic protein concentration and that this explains an observed predisposition to infection in patients with low ascitic fluid protein concentration. This present study aims to investigate the frequency of the recurrence of SBP in a large series of cirrhotic patient who recovered from the first episode of SBP and to identify any possible predictors of recurrent SBP. METHOD: We reviewed records of chart in 312 consecutive cirrhotics with ascites patients treated in our hospital between January, 1988 and August, 1995. RESULTS: The incidence of SBP was 21.8%(68 cases) and showed 80.9% in male, 19.1% in female. Seventeen(25%) of the 68 patients included in the study after the resolution of their first episode of SBP developed one or more episodes of SBP during follow-up. SBP recurred once in 16 of these patients, twice in 1 patients. The cumulative probability of SBP recurrence was 47.1% at 6 months, 64.7% at 12 months, and 82% at 18 months of follow-up. This study reveals that neither ascitic fluid total protein nor the severity of liver disease(Child's class) predicts the occurence of recurrent SBP. CONCLUSON: We conclude that the occurrence of recurrent SBP is unrelated to the type of liver disease, and severity of liver disease did not predict the presence of recurrent SBP. Also, ascitic fluid total protein < or =1.0 g/dl, prothrombin time < or =45% may not be a sensitive predictor of recurrent SBP.

A 21-year-old woman found to be hypertensive was referred for hypertension. On examination, blood pressure was 170/110mmHg in the right arm, 160/100mmHg in left arm,and 120/70mmHg in legs. A grade 2/6 systolic ejection murmur was present at the left upper sternal border, and a chest x-ray revealed a rib notching on the inferior margin of 4th rib. Two-dimensional echocardiogram showed the coarctation of aorta beyound the origin of the left subclavian artery. Biplane TEE demonstrated a discrete narrowing of the descending aorta at the site of coarctation. The blood pressure was 169/86mmHg in ascending aorta and 118/84mmHg in descending aorta. Aortogram showed a localized coarcted aortic segment of 7mm in diameter and 5mm long just distal to the left subclavian artery. Balloon coarctation angioplasty was performed with 7F 30x15mm pediatric balloon dilatation catheter. Balloon position was confirmed on fluoroscopy by the hourglass appearance of the balloon inflation and thereafter, the balloon was inflated until the waist of the balloon disappeared. After procedure, a pull back pressure tracing across the coarctation of aorta revealed no pressure gradient between ascending and descending aorta with 141/90mmHg. Aortogram showed an increase in diameter of the coarctation of aorta to 18mm with aneurysmal formation. 3 months later, follow up aortogram showed no significant change in diameter of coarctation of aorts or aneurysmal formation. Nonsurgical balloon coarctation angioplasty appears to be an alternative therapy for the coarctation of aorta in adults.

BACKGROUND: Elastic recoil contributes to the residual lumen reduction immediately after PTCA. We evaluated the factors to influence on immediate elastic recoil after the successful PTCA. METHODS: 88 patients(96 lesions) were studied by quantitative angiography. Angiograms were obtained in two identical near orthogonal projection before PTCA and immediately after the last balloon deflation. RESULTS: Immediately after PTCA, minimal luminal diameter increased from 0.7+/-0.6mm to 1.9+/-0.6mm and percent diameter stenosis was reduced from 77+/-20 to 34+/-21%. The calculated mean elastic recoil was 0.5+/-0.7mm in diameter and % elastic recoils were lesser both in calcified(3+/-23 vs 23+/-24%, p=0.04) and thrombotic(9+/-20 vs 23+/-35%, p=0.02) lesions. The elastic recoil increased significantly according to the inflation diameter of balloon(r=0.32, p<0.01. No significant correlation between the immediate elastic recoil and age, sex, risk factors, eccentricity and lesion length was shown. CONCLUSION: The elastic recoil immediately after a successful PTCA was dependent on the existance of calcium and thrombus on the target lesion and on the balloon size at the maximal inflation.

BACKGROUND: The clacification of the wall and narrowing of the lumen of the coronary artery is closely related to the process of atherosclerosis and its severity. Thus, the present study of calcified coronary artery lesions by analysis of cineangiography is attempt to define the incidence and factors to affect the coronary artery calcification. METHODS: Our report concerns a consecutive series of 513 patients who underwent coronary angiography between January 1, 1991 and September 30, 1993. We determined the relationship between the coronary artery calcification and sex, age, risk factors, serum calcium, BUN, creatinine, lesional lumen stenosis and severity of coronary artery disease. RESULTS: Among patients with significant coronary artery disease, 22%(62/282 cases) had the coronary artery calcification by cineangiography. Patients with calcification were older(62+/-8 years) than those without calcification(56+/-10 years)(p=0.0001). The distribution of calcified coronary artery was 35 lesions in LAD, 17 in LCX, 16 in RCA and 4 in LM. The calcification rate was 38%(40/104 cases) for patients with multi-vessel disease, compared to 12%(22/178 case) for those with single vessel disease(p=0.0001). Patients with calcification significantly had the long lesion(22.4+/-13.4mm), compared to those without calcification(18.0+/-11.3mm)(=0.012). Coronary artery calcification was correlated with smoking habits. CONCLUSION: Coronary artery calcification was seen in 22 percent and strongly correlated with age, smoking habits, the severity of disease and length of lesion.
