BACKGROUND: Central nervous system dysfunction continues to be a major cause of morbidity after aorta and cardiac surgery under cardiopulmonary bypass (CPB). Pupillary reflexes are important component of the neurologic examination. The purpose of this study was to evaluate how the pupil reacts during hypothermic CPB under fentanyl anesthesia and its relation with postoperative neurologic deficits. METHODS: Fourteen patients undergoing ascending aortic dissection or aneurysm repair surgery under profound hypothermic CPB and circulatory arrest were enrolled. Pupil size and light reflex were evaluated at varying stages of CPB and temperatures. Temperatures were measured at different sites of perfusate, nasopharynx and rectum. Postoperatively neurologic assessments were performed to compare with the pupillary signs. RESULTS: Anesthetic induction with fentanyl decreased pupil size to pinpoint. Pupil dilated progressively under hypothermic CPB reaching fully dilated size at profound hypothermia. Rewarming returned the pupil to original size. Nasopharyngeal temperature correlated well with pupil size during cooling and rewarming. Light reflex was absent at any stage or temperature after anesthetic induction. Seven patients showed insignificant anisocoria and two died of other causes than neurologic deficit. One patient who was not in the anisocoria group exhibited delirium. CONCLUSIONS: Profound hypothermic CPB under fentanyl anesthesia dilates the pupil to a maximum size without light reflex overwhelming narcotic effect. Fully dilated pupil does not denote neurologic damage.

Adenomyoepithelioma of the female breast is a rare tumor. With rare exceptions, the tumor is uniformly solid. We describe a large grossly cystic adenomyoepithelioma in a 67-year-old female. The tumor was histologically benign. The characteristic microscopic finding was the proliferation of rounded tubules lined by both epithelial and myoepithelial cells. Immunohistochemical findings confirmed the presence of two cell population.

BACKGROUND: Controversy exists as to whether or not inhalation anesthetics and intravenous anesthetics impair arterial oxygenation (PaO2) during one lung ventilation (OLV). Accordingly, we examined the effect of enflurane and propofol on PaO2 and pulmonary vascular resistance (PVR) during OLV. METHODS: Forty patients, who had prolonged periods of OLV anesthesia with minimal trauma to the nonventilated lung were studied in a cross over design. Patients were randomized to four groups; Group 1 received 1 MAC of enflurane and oxygen from induction until the first 20 min after complete lung collapse, then were switched to propofol 100 g/kg/min (P100). In group 2, the order of the anesthetics was reversed. Group 3, Group 4 received the same order of the anesthetics as Group 1, Group 2, respectively but received propofol 200 g/kg/min (P200). RESULTS: During OLV, the PaO2 values were lower than those with two lung ventilation (TLV), there were no significant differences among each groups and between propofol and enflurane in PaO2, but in the selected patients (n=10, PaO2<120 mmHg during OLV), PaO2 in propofol group was higher than that of enflurane group (p<0.05). Conversion from TLV to OLV caused a significant increase in PVR, but there were no difference in PVR between propofol and enflurane group. CONCLUSIONS: These results suggest that the usual clinical dose of propofol affords no advantage over 1 MAC of enflurane anesthesia except low PaO2 patients during OLV. Propofol might be of value in risk patients of hypoxemia during thoracic surgery when OLV is planned.

Isolated angiitis of the central nervous system is a rare clinicopathologic entity characterized by vasculitis restricted to the vessels of central nervous system without other apparent systemic vasculitis. It manifests headache, higher cortical dysfunction. focal neurologic dysfunction and cranial nerve palsies. We experienced a case of isolated angiitis of the central nervous system in 6 year-old girl who was admitted to out unit because of headache, hemiparesis and altered consciousness. The laboratory test for blood, urine, and cerebrospinal fluid are all within normal ranges. There was no evidence of systemic vasculitis. The contrast enhanced brain CT scan showed low densities along the left cerebellar hemisphere and posterior aspect of temporal lobe without enhancement, and left lateral internal carotid angiogram showed poorly contrast filling along the territory of left posterior cerebral artery due to narrowing or ischemic changes of the vessels. Axial T2WI (TR/TE, 2190/80) of magnetic resonance imaging showed multiple scattered high signal intensities at left pons with cerebellar hemisphere and diffuse high signal intensity along the left occipital lobe with enlarged surrounding gyral patterns, and axial T1WI(TR/TE, 665/25) showed intense gyral pattern contrast enhancement along the left occipital lobe. Steroid was tried with apparent benefit. We report a case of isolated angiitis of central nervous system with review of literature.

The clinical syndrome of venoocclusive disease of the liver is one of several manifestations of regimen-related toxicity that can occur after high-dose cytoreductive therapy. Hepatic dysfunction after bone marrow transplantation may result from a number of causes such as pretransplant chemoradiation, graft-versus host disease, drugs for prophylaxis of graft-versus host disease, venoocclusive disease, various infections, and infiltration of recurrent malignancy. The clinical distinction of these causes may be difficult and the treatment of each cause is also quite different. Therefore the diagnosis of veno-occlusive disease is important. Veno-occlusive disease affects zone 3 of the liver acinus and produces a syndrome of jaundice, painful hepatomegaly, and fluid retention. Veno-occlusive disease occurs in up to 50% of the patients who undergo BMT and is usually associated with a high mortality rate. In Korea, there are a few case reports on venoocclusive disease after BMT which were only confirmed by clinical symptoms. This is a first report of two cases of hepatic veno-occlusive disease after allogenic BMT, which were proven by laparoscopic liver biopsy in our country.

Cutaneous focal mucinosis was first described by Johnson and Helwig in 1961 and is histo logically characterized by localized accumulation of mucin in the upper and middermis with scattered spindle-shaped fibroblasts. The mucin is jelly-like acid mucopolysaccharide consisting of hyaluronic acid bound to small amounts of chondroitin sulfate and heparin. The pathogenesis of cutaneous mucinosis is unclear. However, studies of various cutaneous mucinoses suggest that there may be an unknown circulating factor that stimulates fibroblasts to produce this material. Differential diagnoses include papular mucinosis, myxoid cyst, cutaneous myxoma. Simple surgical excision is the treatment of choice. In the present case, cutaneous focal mucinosis occurs on the nail bed with onycho mycosis.

Mixed tumor of the skin, so called chondroid syringoma, is a benign epithelial neoplasm with glandular or ductal differentiation surrounded by myxoid stroma. It is most frequently located on the head and neck and presents as an asymptomatic, firm, subcutaneous nodule. Mixed tumor with follicular, sebaceous and apocrine differentiation is considered as an expression of the common embryologic origin of elements of the folliculo-sebaceous-apocrine unit. We report a case of mixed tumor of the skin with follicular, sebaceous and apocrine differentiation.
