Authors attempted to examine the development of keratinocyte in the human fetal epiderrnis in term of the appearance of principal product of differentiation, the keratins. Immunohistochemical study (ABC method) using anti-prekeratin antibodies and anti-keratin antibodies was carried out on sampled skin from 9 human fetuses ranging in estirnated gestational age from 12 weeks to 27 weeks. As early as 12 weeks of embryonic life, the epidermis contained cytokeratin. At this stage of development, the embryonic epidermis consists of three-cell layer .' basal layer, intermediate layer, and periderm, all of them staining for prekeratin and keratin. A thick cornified layer developed at 24 weeks but was not stained for prekeratin and keratin. Hair germ of 12 week-fetus was recognized as bulges of basal cells that were stained for prekeratin and keratin. At 18 weeks of estimated gestational age, development has advanced to the bulbous hair peg stage at which point the primordia of nearly all the final structural components of follicles were established. In the final structureal cornponents of the follicles, outer root sheath and sebaceous gland were stained for prekeratin and keratin, whereas cortical and cuticular elements and inner root sheath were negative. There was no difference between immunostaining results for prekeratin and keratin except for the staining intensity. The appearance of these proteins early in development suggests their potential value in utero in the recognition of keratinization disorders.

Acute tubular necrosis has been rarely reported as a complication of typhoid fever in the literature. We experienced four cases of acute tubular necrosis associated with typhoid fever in children. Patients showed significant titer of widal reaction associated with acute renal failure and one of them rised in 2 months after onset of clinical symptoms. Renal biopsy findings were compatible with acute tubular necrosis and immune complexes were not deposited in the glomeruli. Clinical and urinary findings were normalized by hemodialysis and antibiotic therapies. In conclusion, close longterm follow up of widal titer is mandatory in acute tubular necrosis, especially when associated with high fever.

In spite of vigorous efforts to enhance appropriateness of blood usage in surgery, it is recognized that there are still not a few overuse and misuse of blood products in Korean hospitals. To assure appropriate use of blood, continuous monitoring and controlfling blood orders, particularly for surgical operations, should be implemented. The indicator of 'ratio of crossmatching to transfusion' (C/T ratio) has been focalized on in this regard. The authors investigated C/T ratio for eight hospitals, evenly distributed in their geographical location as well as size. Only elective surgeries operated from March 1 to May 31, 1995 were included for analysis. Standardized survey format was distributed, and retrospective reviews of medical records were performed by volunteer surveyors from each hospital after two sessions of pre- survey education. The results were as follows. Average C/T ratio, for all hospitals and all surgeries, was 1.76. Differences in C/T ratio by sex, months, clinical departments, blood components were not significant. However, the ratio showed increasing tendency with ages. The C/T ratio on the average was not higher, compared with the recommended guideline. However, due to study' s limitations ini standardization of survey method and verification of data, we could not conclude that current status of appropriateness of blood use is satisfactory. In addition, to pervasively use the C/T ratio as a quality indicator for blood use management, supplementary measures, such as standardization of data, should be adopted.

Post-traumatic encephalopathy is characterized by the combination of upper motor neurons, basal ganglia, cerebellar, and psychiatric disturbances. A "striatal" variant, with predominant parkinsonism, is uncommon and may be difficult to distinguish from idiopathic Parkinson's disease. A 38-year-old man, who had history of head injuries associated with brief losses of consciousness, developed a resting tremor and rigidity of the left lower extremity. Upon admission, he showed masked face and bradykinesia without dementia or other neurologic abnormalities. Brain MRI and SPECT studies showed no abnormalities. A BAEP study revealed an abnormal prolongation of inter-peak latencies between wave III and V.

Malignant fibrous histiocytoma is the most common soft tissue sarcoma in adult life and shows a mixed proliferation of both fibroblsstic & histiocytic cells. We report a case of myxoid malignant fibrous histiocytoma involving right lower leg in a 68-year-old male patient, who presented with a childs palm-sized nodular mass of 3 years duration. Histoapthologically, the tumor had varying proportion of myxoid cellular components. The myxoid areas showed spindle and pleomorphic cells arranged in a vague storiform pattern, abrupt transition between a solidly cellular area and a myxoid area, and lipoblast-like cells. The cellular areas showed spindle cells arranged in a storiform pattern characteritic of the typical pleomorphic malignant fibrous histiocytorna.

We report a case of cerebriform intradermal nevus. a cause of cutis verticis gyrata that clinically they resembled neurofibroma and revealed histopathologic finding consistent with intradermal nevus. The patient was a 6 year-old boy, who had a 17x18cm, soft, convoluted. pigmented mass over the parietal and occipital regions. The lesion had been present since birth and had been slowly increasing in size with convolution.

We report two cases of dyschromatosis symmetrica hereditaria. One is a 12-year- old female and her family had five individuals with similar pigmentary disorder through three generation. The other is a 22-yesr-old female who had no family history of similar disease. Fontana-Masson stain revealed increased and decreased melanin granules in the basal cell layers in the pigmented and depigmented lesions respectively.

Cavernous sinus thrombophlebitis may occur as a complication of infectious and noninfectious processes. Septic thrombosis of the cavernous sinuses is a serious life threatening condition, and most commonly follows midfacial skin infections due to Staphylococcus aureus. Isolated sphenoid sinusitis is a rare and elusive clinical problem, and it is an uncommon cause of cavernous sinus thrombosis. We report a case of cavernous sinus thrombophlebitis of spheoid sinusitis origin. A good result has been achieved with immediate medical measures and surgical drainage.
