CT findings of twenty-four patients with adrenal gland tumors were analyzed to evaluate their location, size,shape, density etc. The post-surgical confirmation was made in 17 cases. The findings were as follows: 1. 4-10cmsized tumor messes were most common (42%). 2. Round or oval shaped forme were most common (59%). 3. Functionaltomors were 71% (17/24) including Cushing's syndrome of 10 cases, pheochromocytomas of 6 cases and aldosteronismof 1 case. 4. Abnormal adrenal glands were delineated in 88%(21/24), most effectively by CT. We concluded that CTwas the valuable study in the evaluation of the adrenal gland tumors and in the determination of surgicaloperation.

The eosinophilia-myalgia syndrome associated with ingestion of L-tryptophan in man is defined by the CDC(1989) as follows: 1) eosinophil count more than 1,000 cells per microliter; 2) generalized myaligia(at some point during the course of illness) of severity sufficient to affect a patient's ability to pursue his or her usual daily activities; 3) no evidence of any infection(e.g., trichinosis) or neoplasm that would explain either the eosinophila or the myalgia. The pathologic findings of the eosinophilia-myalgia syndrome varies according to the degree of severity and types of inflammatory cells in the skeletal muscle. In order to simulate this syndrome in animals and further determine its histopathogenesis, L-tryptophan was administered to rats in the laboratory at various doses(25 mg/kg, 50 mg/kg, 150 mg/kg) over a set period of time. In this study, positive histopathologic findings were designated according to the inflammatory cell infiltration of the epimysium and epineurium. Most of the pathologic findings in the positive group were that of inflammatory cell infiltration composed mainly of eosinophils in the epimysial, epineurial connective and surrounding adipose tissues. Only a few necrotic muscle fibers were seen, and there was absence of any evidence of inflammatory cell inflitration in endoneurium or axonal degenerations. Of 59 rats which were given L-tryptophan, 27 rats(45.8%) met the criteria and were designated as belongintg to the positive group. Only 2 rats ingested with L-tryptophan(150 mg/kg) for 2 months and 4 months showed an eosinophil count more than 1,000 cells/microliter. The eosinophil count in the positive group showed significantly different levels when compared to the the negative group and control group. On the other hand, there were no significant differences in the electrodiagnostic study and serum CK, SGOT, SGPT level between the positive, negative and control groups. In summary, histopathologic findings similar to the eosinophilia-myalgia syndrome were inducible in rats followign the administration of L-tryptophan.

We experienced a case of a 38 year old women in whom an alpha-fetoprotein producing carcinoma originated in the rectum. The patient had symptoms of hematochezia and bowel habit change, and a rectal examination revealed an ulcerative mass at the midrectum. The mass size was 6.5 cm 6 cm. The serum alpha-fetoprotein measured preoperatively was 9336 ng/ml, and the serum (carcinoembryonic antigen) was 6.4 ng/ml. The serum level of alpha-fetoprotein decreased to 830 ng/ml thirteen days after a low anterior resection. The tumor mass was a poorly differentiated adenocarcinoma. Using an immunohistochemical staining method, we detected alpha-fetoprotein producing cells in the tumor mass. During the follow up, the serum alpha-fetoprotein level began to increase continuously, and an abdomin opelvic CT scan showed a systemic, local tumor recurrence. Based on our experience with this patient and a review of the literature on the few cases previously reported, it seems that alpha-fetoprotein producing colorectal carcinamas have a tendency to produce frequent blood-borne metastasis and are associated with a poor prognosis.

BACKGROUND: A number of factors can cause dark circles around the eyes including excessive pigmentation, thin and translucent lower eyelid skin overlying the orbicularis oculi muscle, and shadowing due to skin laxity and tear trough. Autologous fat graft is an effective method for the treatment of lower lid dark circles, but irregularities caused by leaving visible lumps of the fat can occur. Tonnard et al. suggested 'nanofat' grafting and introduced its characteristics and clinical applications. The authors used their nanofat grafting to correct lower eyelid dark circles. METHODS: Nanofat grafting was performed in 19 patients for dark lower eyelids. The grafts were injected into subdermal layer using blunt cannula. Microfat grafting with nasojugal fold was performed to all the patients. Among them, 18 patients received transconjunctival fat removal at the same time. RESULTS: All the patients showed much improvement from preoperative dark coloration. There were no visible lumps of fat, contour irregularities, or fat necrosis. Postoperative edema and ecchymosis were minimal. CONCLUSIONS: Nanofat grafting methods provide a good alternative for correcting dark circles by augmenting thin skin with lower complications. This simple, cost effective procedure is suitable for correction of dark circles and various skin rejuvenation purposes.

OBJECTIVE: The purpose of this study is to evaluate the clinicopathologic characteristics of the torsion of the ovarian tumor in postmenopausal women. METHODS: We reviewed the medical records of 20 postmenopausal patients with a postoperative diagnosis of torsion of the ovarian tumor in Department of Obstetrics and Gynecology, Hanyang University Hospital from January 1989 to December 1998. RESULTS: The postmenopausal patients with torsion of the ovarian tumor constitute 20/94 (21.3%) of all adnexal torsion patients encountered during this period. The mean (+/-SD) age of the 20 patients was 63.5+/-9.0 years, with a range of 52-90 years. The mean time since menopause was 16.5+/-10.3 years, with a range of 1-39 years. The mean parity was 5.4+/-2.0 (range of 3-10). Lower abdominal pain (65%) was the most frequently presenting symptom, palpable mass(20%) or diagnosed mass(15%) being the second. But, in 20% of cases there was no lower abdominal pain. The torsion occurred at the right side in 11cases (55%) and at the left side in 9 cases. The most frequent degree of torsion was those cases that was rotated twice (720 degrees). The neoplasms undergoing torsion ranged in diameter between 5cm and 30cm and the most prevalent size was 6 to 10 cm (8 cases). Most of the patients (17cases) were treated by total abdominal hysterectomy and bilateral salpingo-oophorectomy. The tumors that produce torsion varied histologically and the most common type was cystic teratoma (in 5 cases), simple cyst(in 3 cases), serous cystadenoma(in 2 cases), mucinous cystadenoma(in 2 cases). CONCLUSIONS: In our study, ovarian tumor torsion occurring in postmenopausal patients constituted approximately 20% of all torsion patients, therefore adnexal torsion should be considered when a postmenopausal woman presents with lower abdominal pain. When torsion is diagnosed, total abdominal hysterectomy and bilateral salpingo-oophorectomy is the usual treatment for postmenopausal patients. Histologically, in more than 90% of cases, the tumors that produce torsion were benign. If cancer is evident, more extensive surgery is required.

Congenital dislocation of the patella is a rare clinical entity and is considered to result from a failure in internal rotation when the myotome develops, which forms the femur, the quadriceps muscle, and the extensor mechanism. Several authors have suggested various treatment methods, but there has been no consensus on treatment. A 12-year-old boy complained of knee pain and presented with a deformity due to bilateral congenital dislocation of the patella. The patient was treated with surgical management using the Stanisavljevic procedure. We report this case of congenital dislocation of the patella treated with this procedure that achieved a stable patellofemoral joint and satisfactory clinical results over 6.5 years of follow-up. In addition, we have included a review of the relevant medical literature.

Takayasu's disease is characterized by absent upper extremity pulses and ophthalmological finding of secreased visions and catract formation. Clinical features of Takayasu's disease are attributed to an obstructive arteritis of the large vessels criginating from aortic arch and other aortic segments. This dissease most frequently has been reported from Orient, and has affected primarily young females. This is a report of a 10 years old girl who developed the typical clinical and pathophysiological manifestation of Takayasu's disease and we also made brief review of literature.
