Foreign body reaction of tissues is frequently encountered in routine surgical pathology, whether they contain foreign body or not. Though their presence or identification may be the important clue for the legal problems as in malpractice, and the identification of foreign body will give us the chance for reconstruction of patients' medical history, pathologists often overlook or neglect what they are. Besides curiosity, the description of individual foreign body and common site for its occurence will be of great help. Therefore, we classify and describe the features of 182 foreign bodies collected in practice of surgical pathology during 1979~82.

Beta-fluoroethylacetate has been extensively used as the rodenticide in Korea. In some patients with acute poisoning, beta-fluoroethylacetate caused cerebellar dysfunction as a single and persistent neurologic sequela after a period of an acute neurological disorder which is characterized by mental deterioration, seizures, and respiratory failure. But there has been no report of pathological findings to explain neurological deficit. We tried to verify the histologic changes of the central nervous systems in beta-fluoroethylacetate poisoned rats. Silver staining(Gallyas) was used to evaluate the histology. In acute intoxication experiment with LD50(7mg/Kg), beta-fluoroethylacetate elicited acute onset of consciousness deterioration, generalized tonic-clonic seizures and large amplitude tremulous activity involving whole body with full recovery after 24 hours. There was no discernible pathologic change in CNS in acutely poisoned rats. However, when poisoned with sublethal dose(5mg/Kg) daily for five days, a moderate degree of nerve cell degeneration was found selectively in dentate nucleus, Purkinie cell layer, vestibulo-cochlear nucleus and striatum. This change was not seen in hippocampus, cerebral cortex or cerebellar cortex. These findings were well correlated with the previous reports of selective pathology in human 5-FU intoxication cases. Our preliminary results suggest that beta-fluoroethylacetate, a kind of cellular metabolism inhibitor may induce selective neuropathology mainly involving cerebellar output pathway in rats.

To evaluate the differences and factors to be considered when measuring intraocular pressure after photorefractive keratectomy[PRK]and laser in situ keratomileusis[LASIK], we prospectively reviewed the medical records of myopic eyes between -4~-7 diopters. Among them, 14 patients, 22 eyes underwent PRK and 10 patients, 18 eyes recieived LASIK. We measured intraocular pressures by Goldmann applanation tonometry preoperatively, 1 month, 3 months and 6 months postoperatively in each group. Corneal curvatures, central corneal thicknesses were measured and compared when measuring intraocular pressure. The postoperative intraocular pressure was lower than the preoperative value in both groups[p<0.01], and the decreased amount of IOP were not statistically different in both groups[p=0.29]. Targeted ablation depth[p=0.19]and ablation diameter[p=0.16]did not show statistically significant correlation to postoperative IOP decrease. In measuring intraocular pressure after PRK or LASIK, attention should be given to the pressure and its interpretation.

In air leak syndrome, a significant portion of the volume delivered during a positive pressure breath can be lost through the leak. HFOV can achieve adequate ventilation at lower peak and/or mean intrapulmonary pressure than conventional mechanical ventilation (CMV) and has been an effective treatment of already established air leak syndrome. We report a 1-day-old male infant with severe respiratory failure from pneumothorax and pneumomediastinum, who was refractory to CMV with chest tube drainage. HFOV was applied to this patient for 114 hours, and improvement of oxygenation and ventilation as well as significant reduction of pneumothorax followed.

In 1929, Bailey first described an intracranial sarcomatous tumor as a term of perithelial sarcoma. The term of microgliomatosis was introduced by Benedek and Juba, 1941. In recent period, malignant lymphoma was widely used rather than many other terms such as reticulum cell sarcoma, malignant reticulosis, etc. An autopsy case of microgliomatosis was presented. She was a 33-year-old woman with headache, ataxia, memory disturbance, defecation and micturition difficulty. She was relatively well until 3 months earlier before admission. She visited first St. Vincent Hospital due to memory disturbance, and a tumor was found in her left frontal lobe by CT scanning of her brain. She was transferred to Kang Nam Sacred Heart Hospital for further evaluation of the tumor mass. She ws given steroid therapy and somewhat improved in her symptoms. By follow-up CT scannings, the tumor could not be found. Her general conditions were progressively deteriorated and died on 85th day of her admission. Brain limited autopsy was performed. The external features of her brain were grossly unremarkable. Cut surfaces revealed multiple ill-defined grayish white masses, especially on deep white matter of left frontal lobe, left cingulate gyrus and white matter together with medial side of basal ganglia. The definite size was not able to be measured, but the largest one in left frontal lobe was about 2.5cm in diameter. Microscopically, the tumors have many characteristics of microgliomatosis, such as perivascular arrangement of tumor cells and concentric reticulin condensation. These microscopic features were seen not only in grossly visible masses but also in other areas, almost all cerebral hemispheres. Literature review on microgliomatosis and a case report were done.
