Impetigo herpetiformis is a rare pustular eruption that may be seen in late pregnancy. It is associated with severe maternal and fetal complications in case of misdiagnosis and delayed treatment. The patient was a 25-years-old multigravida with psoriasis in her past history. At 20weeks gestation, she had been developed erythematous scaly annular patchs with papules and pustules on inner thigh. At 37weeks' gestation, the patient was suffered from a severely pruritic pustular rash with fever and leukocytosis. The skin of the affected areas was biopsied and showed intraepidermal pustular abscess with a neutrophilic infiltrate. Treatment commenced with intravenous fluids, antibiotics, systemic prednisone, steroid creams, and phototherapy(UVB) under the careful fetal well being monitoring. Cesarean section was done due to fetal distress, and a normal healthy male infant was delivered, following which the patient's condition improved rapidly.

This study was designed to evaluate the therapeutic effect between single(A group) and five-day(B group) administration of IV gammaglobulin in the patients with Kawasaki disease from June 1987 to September 1993, who were admitted to the Department of Pediatrcs, Hanyang University College of Medicine. The clinical and echocardiographic results were as follows. 1) Of 90 cases, 40 cases belong to A group, and 50 cases to B group. The ratio of male to female was 2.60 : 1, and 85% of A group and 76% of B group was under the age of 3 years. 2) In 90% of A group and 88% of B group, peak level of platelet count was above 400,000.mm3, and as a whole peak level of platelet in 88.9% above 400,000/mm3. 3) Complications in S group were hepatitis(22.5%), coronary arterial involvement(12.5%), and gall bladder hydrops(7.5%), and in B group hepatitis(26%), gall bladder hydrops(18%), coronary arterial involvement(12%), pericardial effusion(4%), and meningitis(2%). 4) All 5 cases with mild coronary arterial dilatation in a group had improved in follow up echocardiography after 6 months. And in B group, 5 of 6 cases with coronary arterial involvement had improved, but coronary pathology in one case with large coronary aneurysm sustained after 2 years. In conclusion, we could not find the significant difference in reduction of the duration of illness or the coronary arterial disease between two groups, but we recommend single intravenous infusion of gammaglobulin as soon as possible to prevent severe coronary arterial disease.

Lichen aureus is regarded as an uncommon variant of the pigmented purpuric dermatosis and resistant to treatment. Recently several authors reported the PUVA therapy to be effective in the pigmented purpuric dermatosis, but there was no report that the PUVA therapy was tried to the lichen aureus. We tried topical PUVA therapy on a 54-year-old male with bilateral lichen aureus. After 23 times of topical PUVA therapy, the lesion improved markedly. This report may provide a new method of treatment for lichen aureus.

Colitis cystica profunda is a benign disorder in which a mucous cyst is located in the submucosal layer of, primarily, the pelvic colon and rectum. Radiologic reports of the condition are rare. We report the radiological findings of a case of colitis cystica profunda arising from the proximal ascending colon near the ileocecal valve, and causing intussusception. We also review the literature.

BACKGROUND: Nitric Oxide (NO) has been discovered to be an important endothelium-derived relaxing factor. The exogenous inhaled NO may diffuse from the alveoli to pulmonary vascular smooth muscle and produce pulmonary vasodilation, but any NO that diffuses into blood will be inactivated before it can produce systemic effects. To examine the effects of NO on pulmonary and systemic hemodynamics, NO was inhaled by experimental dogs in an attempt to reduce the increase in pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) induced by hypoxia in dogs. METHODS: Eight mongrel dogs were studied while inhaling 1)50% O2 (baseline), 2)12% O2 in N2 (hypoxia), 3)followed by the same hypoxic gas mixture of O2 and N2 containing 20, 40 and 80 ppm of NO, respectively. RESULTS: Breathing at FIO2 0.12 nearly doubled the pulmonary vascular resistance from 173 56dyn sec cm-5 to 407 139dyn sec cm-5 and significantly increased the mean pulmonary artery pressure from 16 3mmHg to 22 4mmHg. After adding 20~80 ppm NO to the inspired gas while maintaining the FIO2 at 0.12, the mean pulmonary artery pressure decreased (p<0.05) to the level when breathing oxygen at FIO2 0.5 while the PaO2 and PaCO2 were unchanged. The pulmonary vascular resistance decreased significantly and the right ventricular stroke work index returned to a level similar to breathing at FIO2 0.5 by addition of NO into the breathing circuit. Pulmonary hypertension resumed within 3~5 minutes of ceasing NO inhalation. In none of our studies did inhaling NO produce systemic hypotension and elevate methemoglobin levels. CONCLUSIONS: Inhalation of 20~80 ppm NO selectively induced pulmonary vasodilation and reversed hypoxic pulmonary vasoconstriction without causing systemic vasodilation and bronchodilation. Methemoglobin and NO2 were within normal limit during the study.

PURPOSE: To evaluate the usefulness in diagnosing the gallbladder perforation MATERIALS AND METHODS: CT scans of surgically proved 11 cases of gallbladder perforation were retrospectively reviewed. CT findings analyzed were iuminal diameter of GB, GB wall thickness and configuration, presence or absence of fluid collection in the pericholecystic or intraperitoneal space, and observation of pericholecystic anatomic structures. All patients underwent cholecystectomy, and surgical findings were also compared. RESULTS: The GB was distended in 6 cases(55% with a range of 4.0-7.5cm, mean :5.2cm). GB wall was thickened in most cases(9/11,82%) with homogeneous(n=7) or inhomogeneous(n=2) enhancement. At the sites of perforation, focal defect or contour bulging was seen in the GB wall in 3 cases. in 2 cases with gangrene, GB wall showed loss of normal contour with mottled contrast enhancement. Pericholecystic or intraperitoneal fluid co11ection was noted in 9 cases(82%), especially in the region of perforation. In all cases, there was evidence of diffuse infiltration in the pericholecystic space, omenturn or mesentery. Other findings included cholecy-stoenteric fistula in 1 case, and intrahepatic or intraperitoneal abscess formation in 2 cases. CONCLUSION: CT is useful in correct diagnosis of gallbladder perforation.

Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu disease is an autosomal dominant disorder characterized by repeated episodes of bleeding. Multiple telangiectases consisting of thin-walled, dilated vascular channels with arteriovenous communication may involve, for example, mucocutaneous tissue, the gastrointestinal tract, and the liver, lung, and brain. We report the imaging findings of two cases of HHT involving arteriovenous malformation of both the lungs and liver, a rare condition. Chest radiography revealed a round mass, while helical CT showed a feeding artery and draining vein with arteriovenous malformation in the lung. Color Doppler sonography revealed an enlarged and tortuous hepatic artery with high systolic velocity. CT demonstrated an enlarged hepatic artery, arteriovenous shunt, and early draining hepatic vein in the liver. Celiac angiography showed arteriovenous malformation.

BACKGROUND: The purpose of our study was to evaluate the accuracy of reduction based on postoperative computed tomography (CT) images after arthroscopic stabilization using tightrope system for unstable distal clavicle fracture. METHODS: Twelve patients with distal clavicle fracture combined with coracoclavicular (CC) ligament injury (type II, V) who received arthroscopically assisted fixation using a flip button device were evaluated for accuracy of reduction using 3-dimensional postoperative CT scan by measuring the degree of distal clavicular angulation and clavicular shortening. RESULTS: Immediate postoperative plain radiograph confirmed restoration of the CC distance (CCD) in 10 patients. At final follow-up, the CCD remained reduced anatomically on plain radiographs in these patients. All patients showed excessive posterior angulation and shortening compared to the opposite side. The average Constant score recovered to 94.8 at final follow-up. CONCLUSIONS: Indirect reduction and arthroscopic subacromial approach with flip button fixation of unstable distal clavicle fractures demonstrated favorable clinical results despite unavoidable posterior angulation of distal clavicle and shortening the total length of clavicle.
