Dementia is defined as a syndrome which is characterized by various impairments in cognitive functions, especially memory function, Most of the diagnostic criteria for dementia include memory impairment as no essential feature. Memory decline can be present as a consequence of the aging process, But it does not cause significant distress or impairment in social and occupational functionings while dementiadoes. Depression may also be associated with memory impairment. funcitionings while dementiadoes. Depression may also be associated with memory impairment. However, unlike dementia, depression dose not cause decrease in delayed verbal learning and recognition memory. In dementia, different features of memory impairment may be present depending on the involved area. Memory impairment in cortical dementia is affected by the disturbance of encoding of information and memory consolidation, while memory imparnene in subcrotical denentiy is affected y the disturbance of retrieval in subcortial dementia.

Decubitus ulcer is often seen in the skin and underlying tissue of debilitated or immobilized patients as the result of prolonged pressure and impaired circulation. It manifests chiefly as an ulcer over bony prominences, but tumefaction is an extremely unusual presentation. A 53-year old male, a paralytic of the lower extremity for 18 years, developed a recurrent decubital ulcer despite repeated surgical repair, from which a rapidly growing, large fungating mass grew within a month. The last resected mass was bosselated and measured 15x9x3 cm with a major area of cicatrix-like induration, interdigitated with skeletal muscle bundles at the central area. Microscopically, the mass was composed of an upper half of active granulation tissue layer and a deeper half of dense, poorly cellular, fibrocollagenous bundles admixed with florid proliferation of atypical fibroblasts, but the absence of mitosis and the multifocal admixture of active inflammatory process-granulation tissue formation seemed to help exclude genuine fibromatosis, nodular fasciitis or proliferative myositis. We assume that this rapidly growing pseudofibromatosis is an additional manifestation of a prolonged decubitus ulcer, possibly related to the modified reparative process of decubitus ulcer following repeated excisions, for which we propose a term of decubitoma.

A survey for nematode and cestode parasites of rodents in Korea has been carried out at the areas of Chulwon, Kumwha, Pochon, Paju and Chungpyong, Kyunggi-Do. A total of 300 rodents of seven species was examined, comprising of 219 A. agrarius, 33 R. norvegicus, 8 R. alexandrinus, 14 Mus musculus yamashinai, Microtus fortis pellceus, 21 Crocidura russula and a Cricetulus trition nester. The following fifteen species belonging to thirteen genera were identified: NEMATODA: Heterakis spumosa, Syphacia obvelata, Nippostrongylus muris, Protospirura muris, Capillaria hepatica, Capillaria sp., Heligmosomum sp., Heligmosomoides sp., Rictularia sp. and Gongylonema sp. CESTODA: Hymenolepis nana, Hymenolepis diminuta, Raillietina coreensis, Paranoplocephala sp. and Cysticercus fasciolaris(the larva of Taenia taeniaeformis).

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is characterized histologically by massive infilteration of right ventricular wall by fat tissue with surviving strands of cardiomyocytes bordered by or embedded in fibrosis. ARVC has been recognized as a cause of sudden death, especially in the young. We report an autopy case of ARVD/C in a 35-year-old female. She was found dead in her house under apparently natural circumstances. The autopsy revealed a dilated 340-gram heart with a fibrofatty replacement of the right ventricular myocardium. On the review of her past medical history, she had taken medical examination for prolonged general weakness about 1 year prior to death. At that time the echocardiogram revealed dilatation of right ventricular cavity size and moderately decreased left ventricular systolic function, the electrocardiogram revealed R>S at V1 lead and T-wave inversion at V1-V3 leads. To the best of our knowledge, this is the second autopsy case of ARVD/C, reported in the literature of Korea.

Thirty-nine patients with fixed drug eruption who visited the Department of Dermatology in National Medical Center from January 1g7g to December 1982 were selected. Among them, twentyseven patients performed skin biopsy and were evaluated histopathologically on the basis of duration. The results were as follows; ].In the early stage less than 1 week of duration, hydropic degeneration of basal cells, necrotic keratinocytes with eosinophilic cytoplasm and pknotic nucleus in the epidermis, and mixed cell infiltration with eosinophlis in the upper dermis were prominently. In the late stage more than 20 days of duration, acanthosis, an increased amount of melanin in the basal cell layer and presence of melanophages were found more prominent, however, hydropic degeneration of basal cells, papillary dermal ederna, inflammatory infiltration of mononuclear cells were found less prounced or absent.

Basaloid follicular hamartoma (BFH) is a benign adnexal tumor with a wide spectrum of clinical appearance and is characterized histologically by the presence of branching cords and thin strands of undifferentiated anasomosing, basaloid proliferations that are embedded in a fibrous stroma. It has been often misdiagnosed and treated as basal cell carcinoma. We report a 57-year-old woman with BFH on the face which is similar to basal cell carcinorna clinically that turned out to be a solitary BFH histologically. There has been no recurrence during one year of follow up after excisional biopsy.

Acute pyogenic arthritis in renal transplant patient is one of the serious problem resulting in significant morbidity and mortality. The purpose of this paper is to analyze seven patients in whom acute pyogenic arthritis developed following renal transplantation. Pyogenic arthritis developed in seven (0.7%) out of 958 renal transplant patients whose transplanted kidney functioned well for more than two years. The age of the patients ranged from 37 to 65 years with a mean of 48 years. All patients were male. Pyogenic arthritis developed between the period of one and 12 years (mean: 4.5+/-4.2 years) following transplantation. Causative organisms were Staphylococcus aureus (three), E. coli (two), Salmonella (one) and Acinetobacter bananii (one). Involved joints were four knees, one hip, one elbow and one finger. Two patients improved on a conservative regimen of bed rest and antibiotics and five patients required open drainage. However, pyogenic arthritis recurred in three years, four years and seven years after renal transplant in one patient. Looking at the probable risk factors of age, sex, immunosuppresants, diabetics and acute graft rejection, diabetics and older age (over 40 years old) are highly associated with post renal transplant pyogenic arthritis.

Pain, premature degenerative arthritis, stiffness and persisting subluxation are common sequalae of fracture dislocations of the proximal interphalangeal joints of the fingers. With disruption of greater than 40% of the volar articular surface of the middle phalanx, it is un- likely that congrous stable reduction can be achieved. And the most severe injuries are caused by longitudinal compression force, which drives the middle phalanx where the middle phalanx eventually comes to rest. Many authors had reported a variety of method for the treatment of the unstable fracture dislocation with no satisfactory results except Eaton(1980). In his ten years experience the volar plate arthroplasty for acute and chronic fracture dislocations got a good results with satisfactory range of motion and no pain on motion. Authors had been treated two cases of chronic fracture dislocations of the proximal interphalangeal joint with Eatons volar plate arthroplasty followed by good results in one year followed-up study.

The developement of squamous cell carcinoma from the draining sinus of chronic osteomyelitis has long been recognized as a rare and late complication. The mode of developement of carcinoma at the site of chronic osteomyelitis is not well understood. This, however, is chiefly a disease of middle aged men, and tibia is the most common site. There are two types in this carcinoma; superficial and deep types. In the superficial type obvious presence of fungaiing growth makes diagnosis simple and easily confirmed by biopsy. In the deep type the diagnosis is difficult clinically, but the features most frequently described are an increase in pain and discharge with swelling and hemorrhage. Amputation at the adequate level is the treatment of choice. Three cases of the disease involving one left femur, and two left tibiae are reported with review of literature.
