Cutaneous metastases from internal carcinomas are relatively rare, especially from pancreatic carcinoma. Pancreatic carcinomas are usually adenocarcinomas which arise in the head of the gland, and are known to rapidly metastasize to the lymphatic system by permeation and embolization. We report a case of cutaneous metastasis from pancreatic adenocarcinoma. in 74-year-old male patient who have two pea sized, slight erythematous nodules on the lower abdomen and posterior side of the neck.

BACKGROUND: Clinical and experimental studies have suggested that brain death may cause hemodynamic, electrocardiographic, functional or histopathologic changes of the heart. METHODS: Brain death was induced by increasing intracranial pressure(ICP) abruptly by intermittent bolus injection of saline(model ) or gradually by continuous infusion of saline(model ) to the epidural catheter in 5 mongrel dogs, respectively. Hemodynamic and biochemical changes during the process of brain death and histopathologic changes of the myocardium were analyzed and compared in two brain death models, and the association of apoptosis was also evaluated. RESULTS: 1) Two predominant subsets of acute contraction band lesion were produced in both brain death models : paradiscal and holocystic contraction band lesions. Both contraction band lesions were more prevalent in brain death model . 2) The frequency of both contraction band lesions was lowest in the epicardial layer and highest in the endocardial layer in both models, but no correlation was observed between the degree of contraction band lesions and ICP, LV maximum +dp/dt or catecholamine levels. There was no statistical difference between any of the LV circumferential blocks and either type of contraction band lesion, and transaxial distribution was not also different in both models. 3) There was no remarkable histopathologic changes in the analysis of major epicardial coronary arteries. Apoptotic cells were suggested in the scattered myocytes in the light microscopy and apoptosis was detected by in situ nick end labeling method. Electron microscopy revealed a condensation of nuclear chromatin and convolution of nuclear membrane in those myocytes. CONCLUSIONS: Myocardial changes due to brain were observed frequently, and few apoptotic cells were found in the brain death heart. Studies on the treatment strategy to minimize damages of myocardial structure and function caused by brain death should be followed in the near future.

4.Changes of Nerve Conduction at High Temperature in Patients with Carpal Tunnel Syndrome.
Journal of the Korean Academy of Rehabilitation Medicine 2000;24(5):939-945
OBJECTIVE: High body temperature may alter nerve conduction in demyelinated neurons. This study was designed to investigate the changes in nerve conduction parameters in response to the heat applied over the wrist in the patients with carpal tunnel syndrome (CTS). METHOD: 16 hands of CTS patients and 16 hands of normal subjects were involved in this study. Motor and sensory nerve responses were measured at 32degrees C and 42degrees C in all the subjects. Infrared was applied on the wrist to warm the skin to 42degrees C. Changes of relative amplitude, duration, and latency of evoked potentials in median sensory and motor nerves of CTS patients were compared with those of the normal subjects. Correlation between the latency measured at 32degrees C and changes of amplitude of motor and sensory nerve responses after warming to 42degrees C was evaluated in CTS group. RESULTS: Relative reduction in duration of motor responses in CTS group was significantly greater than in normal group. Relative reduction of motor and sensory amplitude, and sensory latency were greater in CTS. There was no significant relation between motor and sensory latency at 32degrees C and relative amplitude reduction in motor and sensory responses at 42degrees C. CONCLUSION: Increase in temperature may increase the number of blocked nerve fibers in patients with CTS than in normal subjects.

5.Causes and Types of Childhood Strokes.
Journal of the Korean Academy of Rehabilitation Medicine 2001;25(1):26-33
OBJECTIVE: We documented childhood strokes in this hospital to ascertain the causes of childhood strokes and the proportion of stroke types. METHOD: We reviewed the medical records and brain imaging studies of all children with possible strokes who were admitted to Asan Medical Center from 1990 to 1999. Our review of charts identified 131 acute childhood stroke patients aged from one to eighteen years old. RESULTS: Seventy boys (53.4%) and 61 girls (46.6%) were involved in this study. The predominant diagnoses responsible for the stroke were arteriovenous malformation (42.0%) and moyamoya disease (24.4%). The diagnoses of 30 stroke patients (22.9%) were undetermined, 16 of them were ischemic and 14 hemorrhagic. The total number of hemorrhagic stroke was almost twice as that of ischemic stroke. As patients aged, the incidence of ischemic stroke decreased while the opposite trend was observed in hemorrhagic stroke. There were 14 death (10.7%) consisting of 13 hemorrhagic stroke patients and 1 ischemic during the admission period. Relapse of stroke were noted in 19 of 131 patients (14.5%) with the main cause being arteriovenous malformation. CONCLUSION: Although the main diagnoses of childhood strokes were arteriovenous malformation and moyamoya disease, the cause of strokes in 23% could not be confirmed. The incidence of ischemia decreased while that of hemorrhage increased with the increase in age. Death, relapse, and complication occurred more frequently in hemorrhagic than ischemic stroke.

The appendiceal mucocele is very rare disease of 0.2% incidence. About 24% of patients are asymptomatic and symptomatic patients present with pain in the right lower quadrant of abdomen in 64%, plapable maas in the right lower quadrant of abdomen in 50%, and rarely, melena, hematochezia, anemia, diarrhea, malaise, and abdominal distension. The gastrointestinal bleeding may be presented in the patient with intussusception, but the massive bleeding is generally absent. We report a case of appendiceal mucocele accompanying with gastrointestinal bleeding and review of literature.

Primary gastrointestinal lymphoma primarily confined to gastrointestinal tract is relatively rare diaease. Although the lymphoma primarily involved colorectum or small bowel was commonly reported than primary gastric lymphoma in Korea, the concurrent primary lymphoma of colon and small bowel is very rare in reported cases. We report a case of combined primary malignant lymphoma of the jejunum and cecum, who was admitted due to melena and anemia. She had right hemicolectomy and end-to-side ileotransverse colostomy at 2 months ago, due to primary colon lymphoma. The laparotomy was performed and identified hard, 2 x 3 cm sized masses on distal 25 cm, 80 cm and 150 cm from the Treitz ligament. The histology of these small ma showed histiocytic lymphoma as same as cecal specimen. In general, the small bowel lymphoma shaws poor prognosis than gastric or colorectal lymphoma due to diffieulty in diagnosis and late symptoms, but this problem could be resolved through the knowledge about primary gastrointestinal lymphoma and the development of diagnostic methods.

BACKGROUND: Defective adhesion and migration of melanocyte may be involved in pathogenesis of vitiligo. Tenascin, a glycoprotein of the extracellular matrix, has a role in cell adhesion and migration. It has been reported that abundant expression of tenascin in vitiligo lesion may inhibit melanocyte adhesion and migration. OBJECTIVE: To investigate the tenascin expression in vitiligo skin lesions and to compare with clinical findings. METHODS: We studied 9 patients with vitiligo. The expressions of tenascin were studied by immunahistochemieal techniques.

Malignant esophago-bronchial fistula is an incurable and distressing condition. The passage of swallowed saliva and solid or liquid food into the bronchial tree causes coqghing and frequent pulmonary infection and collapse. Most patients are unfit for major surgery, but intubation offers a quick, simple and effective treatment with improved length and quality of life. However, intubation with simple esophageal tubes are liable to result in failure to occlude the fistela, migration of the tube, erosion, and in the case of latex tubes, disintegration. To overcome these problems, the fistula is intubated perorally with a prosthesis surrounded by a foam rubber cuff contained ia silicone sheath, in which vacuum can be created. This cuffed prosthesis is the most satisfactory design for the treatment of malignant esophago-bronchial fistula with effiective and gentle occlusion of the fistula without risk of pressure necrosis. We experienced a case of the endoscopic treatment with a cuffed prosthesis for malignant esophago-bronchial fistula. So we report this case with brief review of the previous literatures.
