Two cases of primary carcinoma of the ureter were reported with review of the literatures.

Hemorrhoid and anal fissure are common diseases in Korea. It has been demonstrated that patients with hemorrhoidal disease have increased activity of the internal anal sphincter. The fissure causes increased contraction in the internal anal sphincter, thereby increasing pressure in the anal canal. Many studies have reported differences in the anal canal pressures between males and females. Moreover, some papers have shown that sphincter pressures decrease with age. But the majority of these studies were not specific for the hemorrhoid and anal fissure. Therefore, we studied the effect of age and gender on anal pressure in hemorrhoid and anal fissure. Two hundred ninety six patients with hemorrhoid and sixty eight patients with anal fissure were retrospectively assessed. Anorectal manometry using a radial eight-port catheter was performed during resting and squeezing maneuvers of the anal sphincter. In hemorrhoid reduction in maximal average resting(MARP) and squeezing pressure(MASP) were found from the sixth decade, however in anal fissure reduction in MARP and MASP were found in the third decade. In hemorrhoid significant decrease of MARP and MASP were noted in entire ages of female, however in anal fissure increase of MARP and MASP were noted in fifth and sixth decade of female. In conclusion, in hemorrhoid both resting and squeezing pressure decrease with age in female. In anal fissure both resting and squeezing pressure decrease in third decade and in male with fifth and sixth decade.

With the increasing number of the occupational accidents proportionate to the rapid development of modern culture, fractures of the hand have become one of the commonest fractures of the human body. The authors have reviewed 211 cases of injured hand in industry which were treated in the department of orthopedic surgery, InCheon Severance hospital from Jan. to Dec. in 1989. The following results were obtained; 1. The peak incidence was in the age group from 21 to 30 years in 87 cases (41.2%). Injured males outnumbered females predominantly by 92.9% vs 7.1%. 2. The hand injuries happened most commonly in the day time (from 8 oclock A.M. to 6 oclock P.M.) but there were no differences between month in the year. 3. Most of patients injured hand (73.9%) arrived at hospital within 1 hour after accidents. 4. The commonest cause of the injury was due to electric saw (21.9% ). 5. Of the 98 fracture cases left hand was more frequently involved than right hand and 64 cases monodigit and remained were polydigits. 6. 43 (32.6%) of total 132 fractured sites were index finger and 74 (56.1%) were distal phalanx. 7. The index finger was also most vulnerable to amputation (56.8% out of 44 amputation cases) and the most distal part was more vulnerable to amputation. 8. The most common method was primary closure and splint. The method of treatment was affected in part by the economic and social status of the patients. 9. In order to prevent hand injuries in industry, preventive policy should be established by improvement of working environments, machines and education.

Cystic mesothelioma of the peritoneum is a rare benign neoplasm that occurs predominantly in young to middle-aged women and tends to recur locally. Pelvic viscera is the most common predilection site of cystic mesothelioma. Authors report a case of multicystic mesothelioma of the pelvic pelvic peritoneum. The pelvic ultrasonography showed a large, confluent, and thin-walled multilocular cystic mass occupying the pelvic cavity and lower abdomen. The cystic mass was flattened and elongated. Each cyst of variable size was separated by thin septa and filled with translucent fluid. Cystic mesothelioma should be included in the differential diagnosis of the cystic peritoneal masses, especially in reproductive-aged women.

Extra-adrenal pheochromocytoma accounts for about 10 to 15 percent of all such tumors and the combination of pheochromocytoma and renal artery stenosis is rare. We report an unusual case of extra-adrenal pheochromocytoma causing renal artery stenosis which was developed in a 11-year-old boy and the literatures were reviewed.

Pararenal pseudocyst is a collection of fluid within the renal fascia outside the renal capsule and a relatively rare clinical entity which commonly occur as a result of trauma. either accidental or operative. Histologically, the wall is composed mostly of dense collagenous fibrous connective tissue. with no cellular elements capable of cyst formation. A case of pararenal pseudocyst associated with renal hypertension developed in 6 year-old boy after blunt abdominal trauma was reported.

Cavernous hemangioma of the bladder is the rarest of all bladder tumors. Less than 75 cases were reported in the literatures since Broca reported the first case in 1869. We report a case of cavernous hemangioma of the bladder in a 7-year-old girl and literatures were reviewed.

Abnormalities in the number and function of platelets may contribute to thromboembolic complications in patients with essential thrombocythemia(ET). Physicians often use hydroxyurea which reduces the platelet count for the initial treatment of ET. A 74-year-old man with ET was presented with headache, dysarthria, and right hemiparesis 10 months after discontinuation of hydroxyurea. Initial platelet count was 450x103/microliter and we gave him heparin. However, his platelet count rised upto 1,019x103/microliter within 4 days. He was on hydroxyurea 1.5 g/day and his symptoms improved with decrease of platelet count. We report a case of left MCA(middle cerebral artery) multifocal infarction in ET after discontinuation of hydroxyurea.
