The ability of photochemotherapy(PUVA) or UVA phototherapy to stimulate melangenesis is well known. It is now recognized that the PUVA lentigines, irregular in outline and often more darkly and unevenly pigmented than solar lentigines, are related to the additional pigmentary effects of the PUVA therapy. We present herein four cases of unusual pigmentation after one month of UVB irradiation. Raticulated dark brown pigmentation appeared on the lower extremities of the patients. Histopathologicially, an increase in melanin in the basal layer was found, but no dysplasia or malignant change. We suggest UVB as the cause of this unusual hyperpigmentation.

A giant abdominal aortic aneurysm (AAA) renders surgical treatment much more difficult by deforming the proximal infrarenal aortic neck (shortened length and disturbed angulation), by altering the iliac arteries (marked tortuosity and aneurysmal dilatation), and by displacing abdominal organs. Because the retroperitoneal rupture of giant AAA makes the mesentery more elongated and deformed, compromising its blood flow and thus increasing the risk of mesenteric ischemia such as colon ischemia. We describe here the surgical repair of a large infrarenal AAA with a ruptured huge left common iliac artery aneurysm of 13.5 cm in diameter, accompanied by colostomy due to colon ischemia which occurred during the operation. We discuss the pathophysiology and preventive strategy of colon ischemia during ruptured giant AAA repair.

To investigate MR artifacts induced by metallic implants, scans were obtained using both the ferromagnetic Drake lip and the non ferromagnetic Yasargil clip. Scan were taken through the area of clips using geometrical phantom. The MRI was performed by spin echo technique and gradient echo technique on both 2.0T and 0.5T MR unit. The luthors evaluated the nature and differences of artifacts in each sequence and parameter. Artifacts induced by both lips were noted in the direction of frequency encoding gradient, and consisted of region of signal loss abutted in one side by survilinear region of bright signal. Geometric distortion of image was marked in the Drake clip, out was minimal in the Yasargil clip under both 2.0T and 0.5T. Artifacts were more pronounced in the gradient echo technique than those of the spin echo technique on both 2.0T and 0.5T. Although there were no differences n the nature of artifacts induced by the Drake clip among each parameter in the spin echo technique under 2.0T, artifacts were slightly more pronounced on T2 weighted image under the 0.5T field, but no differences were found in the nature of artifacts induced by the Yasargil clip in the spin echo technique under, both the 2.0T and 0.5T fields. Marked artifacts were induced through the small area of the Drake clip which were included in the scan plane, but induced artifacts were small when a small area of the Yasargil clip was included in the scan plane. It seemed likely hat artifacts were slightly more pronounced in the 2.0T than the 0.5T field in both clips, but objective evaluation of the difference was difficult, In conclusion, these results can be an essential basis for the interpretation of MR images or patents with metallic inplants.

BACKGROUND: Althogh drug euption refers to a common dermatological condition, there are numerous holdbacks on the diagnosis. OBJECTIVE: This study atternpts to define the clinical features and causavite drug of the patients with drug eruptions, and to evalarate the diagnostic value of various skin tests. METHOD: 130 patients with drug eruptions were reviewed clinically. In 54 patients, intradermal test, patch test, and scratch patch test were performed using suspected drugs. Result : The exanthematous eruption(53.0%), fixed drug eruptior.(29.2%), and urticaria(6.2%) were the common types of the drug eruption. The common causative agenst of drug eruptions were antibiotics/antimicrobials, antipyretics/NSAIDs, and CNS depressants. 28 paitients out of the 54 patients on skin tests with suspected drugs had positive results in at least one slinest. CONCLUSION: In our study, we were able to obtain somewhat meaningfi 1 results based on data from the combination of various skin tests.
