The authors analysed 261 cases of mycoplasmal pneumonia in children who were admitted to the pediatric department of Seoul Adventist Hospital between July 1986 and June 1991. The result obtained were as follows; 1) Yearly distribution of the cases showed high in 1987 and 1991, but no significant difference was noted in seasonally or monthly distribution. 2) The peak incidence of age was between 2 and 6 years of age, and the sex ratio of boy to girl was 1.1:1. 3) pulmonary manifestations were asthma in 21 cases (8.0%), atelectasis in 5 cases (1.9%), emphysema in 3 cases (1.2%), pleural effusion in 16 cases (6.1%), otitis media in 4 cases (1.2%) and sinusitis in 9 cases (3.4%). 4) Extrapulmonary complication were hepatitis in 53 cases (20.3%), skin rash in 9 cases (2.4%), proteinuria in 6 cases (2.3%), and hematuria in 4 cases (1.5%). 5) On the chest X-ray examination, the most common type of pneumonia was interstitial pneumonia (94 cases, 39.8%), and unilateral involvement was common (85.6%), and the most common involvement was right lower lobe (83 cases, 41.4%). 6) The relationship between the type of pneumonia and cold agglutinini titer, and between the type of pneumonia and Mycoplasma antibody titer were not found (P>0.05). 7) In the 16 cases of pleural effusion, The type of pneumonia was lobar, lobular (9 cases), bronchopneumonia (7 cases), and interstitial type was not present. The site of pneumonia was left (6 cases), right (9 cases), and 1 case showed bilatrality. The extent of pleural effusion was mild (10 cases), moderate (3 cases), and severe (3 cases). The result of pleural fluid exam in severe cases was all exudate. 8) The mean duration of admission was most common from 6 to 10 days. the mean duration of admission by the type of pneumonia was lobar, lobar (10.71+/-3.40), interstitial (8.78+/-2.14), and bronchopneumonia (8.83+/-2.47). 9) Both mycoplasma antibody test and cold agglutinin test were carried out in 185 cases and sensitivity of mycoplasma antibody test was 55.1%.

It already has been known that various ions were participated in phototransduction mechanism of the vertebrate photoreceptor during the visual adaptation. The vitreous humor(VH)contains certain amount of Na+, K+ and Ca++ as well. However, the roles of these ions are unknown except functioning of metabolic process. Our preliminary electroretinogram(ERG) experiments suggested that the permeability of these ions has light dependent activity during the light illumination. We have supported this suggestion more tangibly by trying out various experiments with bullfrog eyes as a reference of visual adaptation. The results are summarized as follows: 1)According to our atomic absorption spectroscopic measurements, the concentration of Na+, K+ and Ca++ in light adapted VH was higher than that of dark adapted VH. This result indicated that the light-dependention transport systems which affect the ionic movements might be in internal limiting membrane(ILM). 2)The amplitude of ERG b-wave was reduced by concentration decrement of Na+ and concentration increment of K+ respectively. On the other hand, the elimination of Ca++ within ringer solution resulted in b-wave amplitude increment. 3)Treatment of Na+ hannel blockers(TTX, STX)and K+ channel blockers(Ba++, Cd++, Cs+, 4-AP and TEA)in the vitreous humor side induced the increment and the decrement of b-wave response respectively. Taken together, these results suggest that the light dependent Na+ K+ channels exist in the ILM of vertebrate retina which participates visual adaptation.

PURPOSE: Vascular calcification (VC) scores on simple plain radiographic films are known to be associated with coronary artery disease (CAD) and mortality. The present study was designed to demonstrate a correlation between VC scores of the hands and pelvis, and feet and lateral lumbar spine on plain radiographs. In addition, we analyzed the usefulness of checking all the plain radiographs for assessment of pre-existing CAD. METHODS: We recruited 61 hemodialysis (HD) patients from OO Dialysis Center. We checked the plain radiographic films of the feet, hands, pelvis, and lateral lumbar spine and evaluated VC scores with previously reported methods. We defined CAD based on myocardial scans, echocardiography, or coronary angiography. RESULTS: Positive associations were found between the VC scores of the feet, VC scores of the hands and pelvis, scores of abdominal aortic calcifications (AACs), and CAD. Approximately 30% of patients who had CAD could be missed based on a single VC scoring method. Patients who showed any one finding among the AAC scores >5, VC scores of the pelvis and hands >3 or arterial media calcifications of the feet on plain radiographs had a high sensitivity (93.8%) and a high negative predictive value (96.3%) for the presence of CAD. CONCLUSION: Each VC score was highly inter-correlated. All three VC scoring methods on plain radiographic films are useful screening tests for the presence of CAD in HD patients.

Linear lesions of discoid lupus erythemaosus (DLE), subacute cutaneous lupus erythematosus or tumid lupus erythematosus, following the lines of Blaschko, are called linear cutaneous lupus erythematosus (LCLE). Lesions of LCLE appear as linear unilateral erythematous plaques predominantly on the face. Neck, trunk or the extremities may also be affected. Histological findings show hyperkeratosis with follicular plugging, epidermal atrophy, hydropic degeneration and dense perivascular infiltration of the inflammatory cells, including lymphocytes and histiocytes. To our knowledge, four cases of linear lupus erythematosus have been reported in Korean literature. We report three patients diagnosed with LCLE.

Phytophotodermatitis is a condition caused by sequential exposure to photosensitizing substances present in plants followed by ultraviolet light. Several plants (e.g., limes, celery, fig, and wild parsnip) contain furocoumarin compounds (psoralens). It is important for dermatologists to be aware of phytophotodermatitis because it may be misdiagnosed as cellulitis, tinea, or allergic contact dermatitis. We present five patients with a sharply defined erythematous swollen patch with bullae on both feet. They described soaking their feet in a fig leaves decoction to treat their underlying dermatologic diseases. Within 24 hours, all patients had a burning sensation in their feet, and erythema and edema had developed on the feet dorsa with exception of the portion of the skin covered by the sandals. Histopathologic examinations revealed sub-epithelial blisters with intensive epidermal necrosis. Phytophotodermatitis was ultimately diagnosed and, after several days, the patients' skin lesions began to recover upon treatment with systemic and topical corticosteroids. Unfortunately, since there are no studies providing sufficient evidence on the benefits of fig leaves, they should be used with caution.
