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.

BACKGROUND: A variety of benign and malignant tumors can occur in the nail apparatus, causing nail deformities and growth disorders. Clinical diagnosis of nail apparatus tumors can be difficult because of their similar clinical appearance. OBJECTIVE: The aim of this study was to determine the types and frequency of nail apparatus tumors and to assess the types and frequency of nail alterations induced by tumors. METHODS: We retrospectively reviewed the medical records, clinical photos, and histologic slides of 165 patients with nail apparatus tumors who had visited Pusan National University Hospital between January 2002 and August 2012. RESULTS: The most frequently diagnosed benign tumors were digital mucous cysts (22.4%), glomus tumors (21.8%), and subungual exostoses (8.5%). The most common malignant tumors were melanomas (17.0%), squamous cell carcinomas (4.9%), and Bowen's disease (3.0%). We observed nail plate alterations in 80.6% of the cases. All cases of melanomas, fibrous tumors, and subungual exostoses produced nail alterations. Most tumors were treated with surgical management. CONCLUSION: Although the sample size of this study was small, this is the first Korean dermatologic trial to identify nail apparatus tumors. The study findings may prove useful in the clinical diagnosis of various nail apparatus tumors.

BACKGROUND: A variety of infectious, inflammatory, and neoplastic dermatoses can develop on the glans penis, and definitive diagnosis in such cases may be difficult owing to their non-specific symptoms and clinical appearance. Furthermore, data on dermatoses of the glans penis in Korea are limited. OBJECTIVE: In the present study, we aimed to determine the prevalence of dermatoses of the glans penis in Korea and provide clinical data to assist in making an accurate diagnosis. METHODS: We retrospectively reviewed the medical records, clinical photographs, and histologic slides of 65 patients with dermatoses of the glans penis that visited the Pusan National University Hospital between January 2004 and August 2013. RESULTS: Twenty-six types of dermatoses were identified: inflammatory dermatosis was the most common (38/65, 58.5%), followed by infectious (13/65, 20.0%), neoplastic (10/65, 15.4%), and other dermatoses (4/65, 6.2%). The most common dermatosis of the glans penis was seborrheic dermatitis, followed by lichen planus, herpes progenitalis, condyloma accuminatum, erythroplasia of Queyrat, Zoon's balanitis, and psoriasis. In the topographic analysis, the most common type of dermatosis was dermatoses that localized to the glans penis (39/65, 60.0%), followed by dermatoses involving the extra-genitalia and glans penis (22/65, 33.9%), and the genitalia (glans penis plus other genital areas) (4/65, 6.2%). CONCLUSION: This study shows the usefulness of a topographic approach in the diagnosis of dermatoses of the glans penis in Korea. The findings could be used as baseline data for establishing an accurate diagnosis in Koreans.

Various modalities have been used for the treatment of psoriasis, including phototherapy. The choice of psoriasis treatment is based on the characteristics of the lesions, locations and amount of involved body surface area. Narrowband ultraviolet (UV) B therapy is a widely used and highly efficient method for psoriasis. But, large areas of unaffected skin may be irradiated along with the psoriatic lesions during phototherapy. The 308-nm excimer laser is a further development of narrowband UVB and was reported to be an effective and safe treatment for localized psoriasis. We experienced an excellent effect without significant adverse reactions of 308-nm excimer laser in a 9-year-old patient with palmoplantar psoriasis who was recalcitrant to oral cyclosporine and topical calcipotriol/betamethasone treatment.
