BACKGROUND: Recently, many cardiac centers have been using aprotinin to reduce operative bleeding in cardiac operations using cardiopulmonary bypass. A variety of reports have confirmed the effectiveness of the drug in cardiac operations. In addition to the operations which could be considered to cause severe operative bleeding such as redo operation, long cardiopulmonary bypass operation and etc, the use of aprotinin is increasing in the field of primary cardiac operations. Varying doses of regimen have been introduced since the first report by Royston et al, and also various opinions on the effectiveness and safeness of the each regimen have been reported. We reviewed our own experience of the full dose aprotinin regimen(Hammersmith regimen) retrospectively. MATERIAL AND METHOD: From October 1994 to February 1998, 40 cases of cardiac operative patients were randomized into two groups: aprotinin group(20 patients) which received a full dose aprotinin regimen and control group(20 patients) which did not receive aprotinin. To evaluate the degree of bleeding decrease, we analysed and compared the amount of postoperative 6 hours and 24 hours bleeding in the each group. To confirm the renal dysfunction, we measured the postoperative creatinine level. RESULT: In the amount of postoperative 6 hours bleeding, a statistically significant bleeding decrease was demonstrated in the aprotinin group compared to the control group(aprotinin group: 186+/-40cc, control group:409+/-69cc, P=0.010). Similar result was observed in the postoperative 24 hours(aprotinin group:317+/-53cc, control group: 671+/-133cc, P=0.024). CONCLUSION: We concluded that full dose regimen of aprotinin can remarkably reduce postoperative bleeding in cardiac operations without significant renal dysfunctions.

From March 1985 to June 1997, 451 patients of spontaneous pneumothorax treated at Kangbuk Samsung Hospital were reviewed retrospectively. Most of the patients were male (male to female ratio, 8.2:1). The mean age of the primary spontaneous pneumothorax (PSP) was 26.8 years, and that of secondary spontaneous pneumothorax (SSP) was 53.1 years. 330 out of 451 patients (73%) were PSP. The causes of the SSP were mostly pulmonary tuberculosis and COPD: 87 patients (72%), and 24 patients (19.2%), respectively. All the patient were treated by one of the following modalities: 1)rest and oxygen therapy in 42 patients, 2) closed thoracostomy in 208 patients, 3) thoracotomy in 156 patients, 4) VATS bullectomy in 45 patients. The mean duration of postoperative chest tube drainage was as following: thoracotomy 8.3 days, VATS bullectomy 4.7 days. For recent 3 consecutive years, VATS bullectomy has become the more frequently applied operative procedure than thoracotomy in the treatment of surgically indicated PSP, from 33% in 1994 to 78% in 1996. With the minimally invasive thoracoscopic surgery being more prevalent, VATS bullectomy will be able to be the 1st choice of treatment not only for the recurrent pneumothoracies but also for the some selected cases of the 1st episode pneumothoracies. To verify this approach as clinically acceptable one in terms of cost-effectiveness, recurrence rate, etc, a large scale of multi-institutional clinical study will be needed in a sooner time.

To evaluate the effect of steroid and alpha adrenergic blockade in experimental spinal cord trauma, pathological change was observed after 500 gm-cm force was impacted on the exposed cord of the 30 Mongoreal adult dogs. The progression of the pathological changes was compared in time lag with the groups of steroid adminstered and phenoxybenzamine treatment. In the group of the spinal cord trauma without treatment, histopathological findings were classical evolution namely from the central hemorrhage and necrosis to peripheral involvement up to amorphous necrotic pattern of entire cord at 24 hours preparation. In the steroid therapy group after the trauma, the pathological changes were confined in the gray matter around and posterior portion of the central canal in all intervals. Moreover the edematous changes and hemorrhagic necrosis were far less severe than the group without treatment. Although the pathologic change was somewhat less severe in the group which received phenoxybenzamine prior to the trauma than the group administered phenoxybenzamine afterward, these group revealed much severe edema and hemorrhagic necrosis than steroid therapy group. The pathologic change, however, in the groups which received phenoxybenzamine was less severe than the group of the spinal cord trauma without treatment.

We have experienced 19 patients of the cerebral arteriovenous malformation with subarachnoid hemorrhage, who were admitted to the Presbyterian Hospital, Daegu from January 1966 to July 1968, and to the Catholic Medical Center, Seoul from August 1968 to August 1971. All of the patients, who have the cerebral arteriovenous malformation, were proved by cerebral angiography. Since the site of lesions were considered to have close relation to the neurologic deficit and the result of surgery, various analysis of the clinical manifestations and the cerebral angiographic findings were attempted. Of the 19 patients, surgery was performed on 12 patients and its results were analyzed correlating to various types of surgical procedure. Following are the results. 1. From January 1966 to August 1971, there were 100 cases of cerebral vascular anomalies which were proved by cerebral angiography. Among the 100 cases, there were 71 intracranial aneurysms, 19 cerebral arteriovenous malformations, one cavernous angioma, 2 telangiectasis, 5 cerebral rete mirabile, and s Sturge Weber-Dimitris disease. The ratio of arteriovenous malformatons to aneurysms was 1: 3.7. 2. Age distribution of the bleeding arteriovenous malformations was ranged from 8 to 54, and 42 per cent of them were in the third decade. 73 percent of the group had bleeding from the cerebral arteriovenous malformation before the age of 40. The ratio of male to female was 1.9:1. 3. The parietal region was most commonly involved by the malformations. There were 8 parietal lesion, 4 temoroparietal lesions, one temporal lesion, one occipital lesion, and one tela chorioidea lesion. Simultaneous involvement of the both hemispheres occurred in one case. In lesions involving the cerebral hemisphere, there was a predominance of the left side. 4. In the past history, convulsive seizure was recorded in two cases and recurrent hemorrhages were reported in two. One patient was recorded to have suffered fourth hemorrhage and the other have sufferd third hemorrhge. 5. Meningeal irritation signs were most frequently observed in bleeding arteriovenous malformations. The incidence of weakness of extremities was higher in lesions involving the parietal area. Unconsciousness was occurred in 6 patients at the onset of symptom, of which transient loss of consciousness was seen in 3 patients. Transient hypertension at the onset was observed in two patients. 6. The feeding arteries of the malformations were most frequently seen from the middle cerebral artery and the draining veins from the malformations were into the superior sagittal sinus and internal cerebral vein in many cases. It was evident that the carotid artery of the sites of arteriovenous malformations was markedly dilated in 5 patients. 7. Ligation of the vessels feeding the arteriovenous malformations was carried out in 8 patients. One patient had neurologic deficit after the operation. Evacuation of intracerebral hematoma, resection of the anomaly or carotid ligation were carried out in 4 patients. Of the 12 patients who underwent various types of surgery, there was one death after evacuation of a large intracereral hematoma. 8. In our opinion, the ligation of feeding artery a choice of procedure to reduce the incidence of rebleeding, if the resection of the lesion was considered to have operative risk by the location of malformations.

This experiment was performed to define the paricipation of a discrete hypothalamic neural structure in the genesis of pulmonary edema and the effect of alpha adrenergic blockade. Fifty adult cats weighing 2.5 to 4.0 Kg, were used in this study. The components of the pathophysiological systemic changes, lung weight, and histopathological changes of lung and hypothalamus were studied in groups of animals when intracranial pressure(ICP) was raised to 200 mmH2O of 300 mmH2O for 2 hours by intraventricular infusion with normal saline. The animals were divided into 5 groups : The normal control group was comprised in 10 normal cats. Control and phentolamine treated animal groups which had an elevated ICP of up 200 mmH2O consisted of 10 cats each. Control and phentolamine treated animal groups which had an elevated ICP of up to 300 mmH2O consisted of 10 cats each. The results obtained were as follows : 1) In the animal groups of elevated ICP to 200 mmH2O or 300 mmH2O, there were hemodynamic systemic changes which were neurogenically mediated and caused an immediate elevation in blood pressure of 30 mmHg to 60 mmHg. The hemodynamic data of the animals that had an elevated ICP of up to 300 mmH2O were significantly more deviated from normal control values than the 200 mmH2O ICP groups. The hemodynamic responses of the phentolamine treated animal with elevated ICP of up to 200 and 300 mmH2O were less deviated from normal control values. 2) The lung weights of the animals with an elevated ICP of up to 200 and 300 mmH2O were significantly heavier than the normal control value(p<0.05) and the lung weights of the animals with an elevated ICP of 300 mmH2O were significantly heavier than those with an ICP of 200 mmH2O(p<0.01). The lung weights of the phentolamine treated animal groups were significantly lighter than the control group but showed little increase in the lung weight when compared to the normal value. 3) By controlling the elevated ICP above 200 mmH2O in the experimental animals we have confirmed gross and microscopic appearances of hemorrhagic pulmonary edema. Histopathological changes of the phentolamine treated animals were significantly less sever than in the control groups. 4) By elevating ICP above 200 mmH2O in the experimental animals, we have confirmed discrete bilateral hemorrhagic spots of the anterior hypothalamus, preoptic region induced by increased intracranial pressure. Histopathological changes of the phentolamine treated animals with the elevated ICP were significantly less severe than of the control groups. 5) This experimental model may define the specific particification of the hypothalamus in the pathophysiological pathogenesis of neurogenic pulmonary edema. These results suggest that the lungs are directly affected by the intense sympathetic discharge evoked by release phenomenon from the sympathoinhibitory influence of the hypothalamus, and pulmonary edema was effectively eliminated by alpha adrenergic blockade.

Angiographic diagnosis of lesions of the posterior fossa requires detailed knowledge of the normal anatomy of both arteries and veins of the brainstem and cerebellum. For this perfuse we measured normal distribution of the vertebrobasilar vessels from three base lines namely clival line, Twining line and foramen magnum line. In the measurement are also included some of the methods which were published in the past. This paper is based on the results of the measurements on 18 cases of normal vertebral angiogram among 77 cases of serial vertebral angiography performed at Catholic Medical center from October 1972 to August 1975. The result obtained were as follows: 1) Distance from the most posterior portion of the pericallosal artery to the clival line is 6.55+/-0.68 cm. 2) Distance from the most posterior portion of the arcuate portion of the lateral posterior choroidal artery to the clival line is 5.16+/-0.61 cm. 3) Distance from the posterior portion of the quadrigeminal portion of the medial posterior choroidal artery to the clival line is 4.87+/-0.67 cm. 4) Distance from the most posterior portion of the distal segment of the medial posterior choroidal artery to the clival line is 4.47+/-0.49 cm. 5) Distance from the bifurcation portion of the basilar artery to the clival line is 1.22+/-0.26 cm. 6) Distance from the forward convexity of the basilar artery to the clival line is 0.15+/-0.11 cm. 7) Distance from the choroidal point to the clival line is 2.99+/-0.51 cm. 8) Distance from the posterior medullary portion of the PICA to the clival line is 2.58+/-0.45 cm. 9) Distance from the tuberculum sellae to the Torcular Herophilli(Twining line) is 10.96+/-0.52 cm. 10) Distance between the tuberculum sellae to the point on the Twining line crossed by a perpendicular line drawn from the choroidal point is 6.61+/-0.40 cm. 11) Distance from the superior portion of the anterior culminate segment of the superior cerebellar artery to the Twining line is 3.28+/-0.48 cm. 12) Distance from the supratonsilar portion of the PICA to the Twining line is 0.97+/-0.42 cm. 13) Distance from the colliculocentral point to the clival line is 3.74+/-0.37 cm. 14) Distance from the crural portion of the anterior pontomesencephalic vein to the clival line is 1.65+/-0.33 cm. 15) Distance from the crural portion of the anterior pontomesencephalic vein to the colliculocentral point is 2.51+/-0.35 cm. 16) Distance from the copular point to the clival line is 3.99+/-0.51 cm. 17) Distance from the copular point to the line drawn from the anterior margin of the foramen magnum is 1.63+/-0.38 cm. 18) Distance from the highest point of the lateral posterior choroidal artery to the Twining line is 4.74+/-0.37 cm. 19) Distance from the highest point of the medial posterior choroidal artery to the Twining line is 4.35+/-0.34 cm. 20) Distance between two bisected points of the anterior culminate segment of the superior cerebellar artery by a line drawn parallel to the Twining line at 1cm from the top of the anterior culminate segment is 2.86+/-0.29 cm.

BACKGROUND: Lichen planus is a chronic papulosquamous disease characterized by various clinical manifestations of the skin, mucosa, hair, and nails. Various drugs or physical treatments for lichen planus have been proposed, but the efficacies are often disappointing and controversial. Linear lichen planus is a rare variant of lichen planus, which accounts for 0.2~0.6% of all patients with lichen planus. Systemic corticosteroids remain the most widely used treatment for lichen planus. However, there have been no clinical studies on the effectiveness of this therapy on linear lichen planus despite the fact that linear lichen planus usually lasts for more than 1 year and occasionally results in cosmetic problems. OBJECTIVE: This study evaluated the efficacy and safety of oral methylprednisolone therapy for linear lichen planus. METHODS: Retrospective study was performed by reviewing the medical records and clinical photographs of 12 linear lichen planus patients treated with oral methylprednisolone. The analyses of treatment response to oral methylprednisolone therapy, adverse effects, and recurrence were performed. RESULTS: All the 12 patients who completed the oral methylprednisolone therapy achieved complete response. Most patients showed a marked improvement 1 to 2 weeks after starting oral methylprednisolone therapy. Three of the 12 patients showed recurrence at 9 to 14 weeks after cessation of the treatment. Oral methylprednisolone therapy was generally well-tolerated and no serious adverse effects were observed. CONCLUSION: Oral methylprednisolone therapy is an efficacious, safe, and tolerable treatment modality for linear lichen planus.

Angiomyxolipoma is a rare variant of lipoma and seven cases have been reported in the English literature. The reported cases mostly presented with a well-demarcated, asymptomatic, solitary, subcutaneous mass on the scalp or extremities. Histopathologic features of this tumor are characteristic and consist of the paucicellular myxoid areas and the mature fat tissue, with numerous thin, dilated blood vessels. The important histopathological differential diagnoses include myxoid spindle cell lipoma, myxoid lipoma, angiolipoma, angiomyolipoma, superficial angiomyxoma, myxoid liposarcoma and low-grade myxofibrosarcoma. We describe a 38-year-old man with multiple angiomyxolipoma on the gluteal area and the upper and lower extremities.

Acute hemorrhagic edema of childhood or infancy (AHE) is a benign form of leukocytoclastic vasculitis with many similarities to Henoch-schonlein purpura (HSP). It occurs in children younger than 2 years and is characterized by abrupt onset of inflammatory edema and ecchymotic purpura in a target or cockade pattern, that resolve spontaneously within 3 weeks. AHE had been considered by some as a variant of HSP which shares certain clinicopathologic features. But most authors have regarded it as an entity distinct from HSP in view of the younger age of patients, lack of visceral involvement, distinctiveness of cutaneous lesions, absence of perivascular IgA on immunofluorescence, and excellent prognosis. We report a typical case of AHE presenting with a cockade or target-like purpura and edema on the face and acral areas with excellent prognosis in a 13-month-old boy.

X-linked dominant chondrodysplasia punctata is a rare congenital disorder characterized by transient punctate epiphyseal calcifications and ichthyotic skin changes, usually resolving during early infancy. We experienced a baby girl born with a thickened and diffusely red integument with adherent scales following the lines of Blaschko and punctata calcification, flat nose. We report a case of condrodysplasia punctata, X-linked dominant type which was confirmed with gene study.
