Histiocytosis X is characterized by aggregates of Langerhans cells with other inflammatory cells. These Langerhans cells are antigen-presenting cells to T lymphocytes and identified by characteristic morphology, ultrastructural demonstration of Birbeck granules and immunologic reactivity with OKT-6 and HLA-DR antibodies. In this report, the tumor arising in a 2-years-old baby was examined byimmunostaining with several macrophage/dendritic cell markers. The main tumor cells showed cytoplasmic and nuclear staining with S-100 protein and ring-like surface and paranuclear staining with PNA. However, they were negative for follicular dendritic cell marker CD21, macrophage markers lysozyme, Mac 387, alpha-1 antitrypsin and CD68, and interdigitating reticulum cell marker ID4 and ID5. These observations demonstrate the usefulness of S-100 protein and PNA for the identification of Langerhans cells in paraffin-embedded tissue.

BACKGROUND: To know the effect of droperidol and ondansetron on nausea and sedation in postoperative patients, we studied 120 gynecological patients receiving patient-controlled analgesia (PCA) with morphine and droperidol or ondansetron. METHODS: Subjects were randomly allocated to one of four groups according to PCA regimen, morphine 0.5 mg/cc alone (group M); morphine plus droperidol 0.034 mg/morphine 1 mg (group D); morphine plus ondansetron 0.132 mg/morphine 1 mg (group O1); morphine plus ondansetron 0.066 mg/morphine 1 mg (group O2). The PCA device, WalkMed was set at basal rate 2 ml/hr (1 mg/hr), bolus dose 1 ml (0.5 mg), lockout time 10min, 1 hour maximum dose 4 mg. The severity of nausea, sedation and pain were assessed at 1h, 4h, 8h, 12h, 24h, and 48h postoperatively. RESULTS: The occurrence of nausea was not different among groups. But there were statistical differences in the nausea severity (p<0.05). The group D and group O1 had lower nausea scores, and between them there was no difference. The scores for sedation were significantly lower in the group O1 compared with group M and group D (p<0.05). Overall pain scores were not different among groups. CONCLUSIONS: Ondansetron and droperidol are effective in reducing nausea. Ondansetron is superior to droperidol in avoiding excessive sedation.

Alzheimer's disease (AD) is an age-related disorder. Both the prevalence and the incidence of AD double approximately every 5 years after the age of 60. This is a particularly serious problem considering that the Korean elderly population is rapidly growing. We present three illustrative cases of AD in mild, moderate, and advanced stages, respectively. Their initial symptoms were memory impairment which was followed by language disturbance and visuospatial dysfunction. Abnormal behaviors such as delusion and aggression occurred in moderate and severe cases. The presence and severity of dementia in these cases were established by history taking, neurological examination, standardized mental status assessment, and neuropsychological test. Laboratory investigations showed no abnormalities that could account for the cognitive deficits. Brain CT or MRI findings of the patients wee not remarkable except for a diffuse atrophy demonstrated by increased ventricular volume, narrowed gyri, and widened sulci, As an addendum, risk factors, clinical symptoms, clinical diagnosis, and natural history of AD were reviewed.

Elastofibroma is a rare benign tumorous growth presenting as a slowly growing ill-defined mass of fibroblastic tissue occurring in elderly persons and arising mainly form the connective tissue between the lower portion of the scapula and the chest wall. Its pathogenesis is not well established but it may be the result of nonneoplastic reactive hyperplasia taking place with constitutional predisposition in the background. A case of elastofibroma occurring in the subscapular area of a 65-year-old female cook is presented. The mass, 6x5x3 cm in maximum dimensions, was poorly circumscribed, solid, hard, pale fleshy and pray-white fibrous tumor. Microscopically, it was composed of numerous small globular and linear elastic fibers embedded in collagenous matrix. To our knowledge, it is the first case of elastofibroma in Korea.

BACKGROUND AND OBJECTIVES: Although pain resulting from thalamic stroke was described by D jerine & Roussy in 1906, its pathomechanism & anatomical substrate have not been defined yet. Several clinical & experimental studies suggest that laterality of lesion for generation of central pain is as important as location of lesion. We performed this study to evaluate clinical features of thalamic pain syndrome, including incidence, onset interval from stroke, nature, distribution, accompaniments, and to assess the relationships between laterality & location of lesion and occurrence of pain. METHODS: We reviewed the medical records and brain imaging of all patients with thalamic stroke from 1990 to 1997. Patients with thalamic pain syndrome due to a single well-demarcated thalamic stroke were included, and excluded tumoral, non-vascular etilogy, and patients with sensory deficit without pain and excluded patients who had multiple cerebral lesions even they have thalamic pain syndrome. RESULTS: One-hundred one cases were selected under the inclusion criteria, and twenty-four patients(24%) with thalamic pain syndrome were identified from 101 thalamic stroke. Pain onset within the first week poststroke was 17(71%). The patients with allodynia were 8(33%), increased by movement, stress, and thermal contact. The painful area distributed mainly limbs(50%), especially arm(35%), face plus hemibody(34%), and hemibody below face(8%). Thalamic pain syndrome accompanied with the pain and temperature loss was 17(71%). Thirteen patients had a right-sided lesion, 11 left-sided lesion. The lesion causing thalamic pain syndrome mainly located in the posterolateral areas(75%). CONCLUSIONS: We conclude that the thalamic pain syndrome resulting from mainly posterolateral thalamic lesion cause the spontaneous pain on the contralateral body, especially upper extrimity, and accompanied with pain & tempterature loss. The laterality of lesion is not represent for generation of thalamic pain syndrome. Key word : thalamic stroke, central pain.

The authors experienced a case of pulmonary alveolar proteinosis. A 58-year-old woman presented with 6 months duration of cough sputum and multiple patch mottled densities in both lung fields. Major histologic finding was filling of the alveoli by Periodic-Acid-Schiff-positive proteinaceous material with maintenance of normal alveolar architecture. Osseous metaplasia was seen in the alveolar space, focally. Ultrastructural study revealed numerous lamellar bodies in alveolar spaces. The immunohistochemical study using antibody to surfactant apoprotein revealed positive reaction in proteinaceous material.

As a contrast to the surgery described in part I, a lamellar undermining was performed in a conventional way. The sclera was lamellarly undermined on the retinal hole areas which extended at least 3 mm beyond the disc edge of the retinal breaks. If the scleral buckling with a circling element is indicated the location of the undermined area determines whether the circling band must follow the globe's equator or another great circle around the eye, The technique for decreasing a vitreoretinal traction used in this series of cases was that proposed by Schepens. Of 56 surgical procedures for retinal detachment, there was a case of an unsuccessful closure of the retinal break due to fishmouthing of the posterior edge of the break. The technique proposed by Schepens was sufficiently promising. But it has the following drawbacks; difficulties in exact hole localization in a high detached retina, anchoring sutures of the circling band behind the equator and problems to protect the vortex veins from the circling band etc. Our experience since 1978, led us to modify the conventional view, in favor of the circumferential buckling on the equator.

OBJECTIVE: This study analyze the standpoint of newspapers toward alternative medicine. METHODS: Through the content analysis of the articles selected by Korean Integrated News Database System(KINDS). With news items about alternative medicine in nine general dailies for six years between 1997 and 2002, this study was conducted to grasp the trend of the reports and provide investigation data to the alternative medicine communication. RESULTS: As social concerns about health drastically increase, many types of health information and common senses in medicine are recently pouring out through various media. Newspapers and TV are competitively presenting items and programs about health every day. Now anyone can approach information and common senses in medicine with ease if he or she wants. The problem is that reports and programs about health pouring out through each medium contain a great amount of wrong information that can have a bad influence on national health. If wrong information is delivered to the people, or medical consumers, through the mass media, they can suffer from very serious side-effects and aftereffects. If patients or caregivers misled by false information on health commit an error in judgement, they can make their disease worse or miss the proper moment for treatment and consequently meet an irrevocable misfortune. For this reason, they must be careful in dealing with information on health. CONCLUSION: In consideration of results, many type of health information are expected to grow in the future. Therefore it is important for information providers to maintain a sound policy which is scientific and objective in order to protect information consumers.
