Chest CT scans of 70 patents with malignant lymphoma were reviewed to evaluate the thoacic manifestation of malignant lymphoma. Sixteen patients had Hodgkin's disease and 54 patients had non-Hodgkin's lymphoma. The thoracic involvement of malignant lymphoma was observed i 47 patients (67.1%) and 11 of these patients had Hodgkin's disease, and 36 had non-Hodgkin's lympoma. The most common finding was mediastinal lymphadenopathy and the most frequently involved sites were anterior mediastinal and paratracheal lymph nodes. Pulmonary parenchymal involvement was seen in 11 patients (15.7%), and CT scan showed thickening of bronchovascular bundle, parenchymal consolidation and nodules. Pleural effusion was seen in 18 patients (25.7%), however, without any evidence of parietal pleural thickening in all cases. Involvement of chest wall and breast was seen in two patient(2.9%). The data obtained through the current study showed no differences from those of previous reports, except the fact that there was no CT evidence of pleural thickening in patients who had pleural effusion.

: In order to know the species and frequency of human parasitic infection diagnosed by biopsy, 149 cases (0.18%) of parasitic infection were reviwed, which were selected from 80,947 biopsied materials submitted for routine histopathological examination during a period of 10 years from 1980 to 1989 at Department of Pathology, Chonnam National University Hospital. They consisted of 112 cases of cysticercosis, 17 paragonimiasis, 7 clonorchiasis, 4 amebiasis, 1 sparganosis, 1 enterbiasis, 1 aniskiasis, and 1 fascioliasis respectively. Based on morphological preservation of cysticercus, they could be divided into mild (20.2%), morderate (40.4%), and severe (39.4%) degeneration. Except 2 cases biopsied at the lungs, 15 cases of ectopic paragonimiasis were located at abdominal cavity (8 cases) and central nervous system (7 cases). One case of intrahepatic fascioliasis was observed. This is the 13th human fascioliasis reported in Korea. From the above results, the frequency of parasitic infections found in biopsied specimens was on the decrease as the cysticercosis and ectopic paragonimiasis.

Most of the peripheral nerve injuries from crushing or compressive forces are accompanied by surrounding soft tissue injuries. As a result, poor vascularity due to fibrosis and sacr formation compromises regeneration of the grafted nerve. Vascularized nerve graft shows superior regeneration to that of a non-vascularized one. However, the human body provides few donor sites of vascularized nerve graft clinically. We presumed that the prefabricated myoneural or adiponeural flap, which include fabricated nerves wrapped with surrounding vascularized muscle or adipose tissue flap, influences superiorly on the regeneration of grafted nerve because that surrounding vasculatity indirectly enhances the vascularity of the grafted nerve itself. Thirty adult male Sprague-Dawley rats were divided into three groups: 1) conventional reversed autogenous graft of the femoral nerve alone(n=10); 2) nerve graft entubulated with abdominal adipose tissue flap with a pedicle of inferior epigastric artery(n=10); 3) nerve graft entubulated with adductor muscle flap with a pedicle of the first muscular branch of the femoral artery(n=10). At three months postoperatively, grafted nerves were examined by electrophysiologic study to check amplitudes and motor nerve conduction velocities, as well as histopathologic study for evaluation of regenerated nerve cells, fibrosis and neo-vascularization. Consquently, nerve regeneration was found in all three groups. Both the myoneural and adiponeural flap groups had better improved results of nerve regeneration compared to that of the conventional nerve graft group. The result of myoneural flap group was superior to that of the adiponeural flap group. The myoneural flap group showed minimal fibrosis and less prominent neovascularization around moderately regenerated nerves. The adiponeural flap group showed more severe perineural and endoneural fibrosis, as well as vascular proliferation around focal regenerated nerves. The results of myoneural flap group proved to be statistically significant. We concluded that it is possible to use nerve graft entubulated with a vascularized muscle flap (myoneural flap) as a substitute for vascularized nerve graft.

PURPOSE: The objectives of the current study are to assess the accuracy of X-Ray Micro Computed Tomography (microCT) in measuring enamel thickness and to evaluate enamel thickness in maxillary incisors of Koreans. MATERIAL AND METHODS: Five maxillary incisors were embedded in resin block. These teeth were longitudinally sectioned labiolingually through the medial axis. After polishing, the teeth were scanned using a microCT (X-EYE SYSTEM; DRGEM, Seoul, Korea). On a scanning electron microscope (S-4300; Hitachi, Tokyo, Japan) (x20) and a microCT, nearly identical planes were reconstructed. In each tooth, the thickness of labial enamel was measured 1, 3 and 5 mm above the cementoenamel junction (CEJ). Thus, the accuracy of the microCT was evaluated. In addition, using 26 maxillary central incisors and 11 maxillary lateral incisors, in the medial axis and 2 mm remote areas mesially and distally from the medial axis, the thickness of labial enamel was measured 1, 3 and 5 mm above the CEJ along the long axis of the teeth RESULTS: Measurements from nearly identical planes in physical and microCT sections differed by 3.81%. An independent t-test was performed and this showed that there were no significant differences in the measurements between the two methods. Mean values of labial enamel thickness in maxillary central incisors 1, 3 and 5 mm above the CEJ were 0.32 +/- 0.01, 0.50 +/- 0.02 and 0.70 +/- 0.02 mm, respectively. Mean values of labial enamel thickness in maxillary lateral incisors 1, 3 and 5 mm above the CEJ were 0.30 +/- 0.01, 0.55 +/- 0.03 and 0.80 +/- 0.02 mm, respectively. CONCLUSION: In measuring enamel thickness, microCT is one of useful way of measurement. So according to the results of this research, when restoring a porcelain laminate veneer on maxillary incisors in Koreans, careful consideration is needed in the amount of enamel reduction.

We observed the neonatal skin to investigate the incidence and clinical features of birthrnarks. We examined 1791 newborn babies admitted in the nursery of Kangnam Sacred Heart Hospital from July 1987 to July 1989. The results were summarized as follows. 1. Mongolian spots were observed in 1435 neonates (80.1%), occurring most frequently on the lumbosacral area. 2. Salmon patches were observed in 416 neonates (23.2%), the nape of neck being the most common site. 3. Pigmented lesions were observed in 20 neonates (1.1%). 4. Portwine stains were observed in 15 neonates (0.8%). 5. Epidermal nevi were observed in 4 neonates (0.2%) and nevus sebaceus developed in one baby.

OBJECTIVES: This study is to evaluate the prevalence, incidence, and risk factors of cognitive impairment and depression in the elderly in community. METHODS: This study was a one-year follow-up of Yonchon cohort aged 65 years and over, selected initially in a prevalence study of dementia and depression. A sample of 790 elderly persons who completely interviewed in a prevalence study was re-interviewed with one year interval using the Korean version of Psychogeriatric Assessment Scale (K-PAS). RESULTS: A total of 631 elderly persons was completely interviewed in this follow-up study. The prevalence of cognitive impairment and depression were 21.4% (11.9% in males and 28.3% in females) and 8.4% (6.3% in males and 10.0% in females), respectively. The one-year incidence of cognitive impairment and depression were 11.4% (5.7% in males and 16.2% in females) and 5.1% (3.1% in males and 6.6% in females), respectively. The risk factors of the prevalence of cognitive impairment were education, age, sex, history of stroke, and economic status. The risk factors of the prevalence of depression were family history of depression, history of stroke, marital status, and economic status. The risk factors of the incidence of cognitive impairment were female gander, education, age, alcohol use disorder, marital status, and economic status. The risk factors of the incidence of depression were low education, disrupted marital status, and poor economic status. CONCLUSION: Cognitive impairment and depression were frequent in the elderly. Several risk factors for cognitive impairment and depression were identified. These results suggest that comprehensive health and social services were needed for the elderly.

Annular erythema associated with lupus erythematosus/ Sjogrens syndrome has recently been described in Orientals. We present a patient with recurrent annular erythema who partially demonstrated features of lupus erythematosus. A 32-year-old man was referred to us for recurrent annular erythema. Laboratory findings revealed mild leukopenia and the presence of antinuclear antibodies at a titer of 320 with a finely speckled pattern on Hep-2 substrates. Anti-Ro/La antibodies were also detected. A skin biopsy specimen revealed the findings of perivascular and periappendageal lymphocytic infiltration without prominent hydropic degeneration of the basal layer. Skin lesions subsided with hydroxychloroquine (400-200mg/day).

A 4-year-old girl developed acute motor, sensory impairment, lower abdominal pain and urinary dysfunction after URI. In acute stage of disease, MRI showed diffuse spinal cord swelling and high signal intensity on T2WI below T2 body level. The patient did not improved and one month later, follow-up MRI showed diffuse spinal cord atrophy and syrinx formation as sequelae of ATM on T1WI below T9 level. To our knowledge, this is the first case showing the sequelae of acute transverse myelitis seen in Korea.
