PURPOSE: To evaluate the health status of institutionalized handicapped children, a general health assessment was done in an asylum in Taegu in May 1998. METHODS: Body measurements, including height, weight, head circumference, skin fold thickness and mid-arm circumference, were done with physical examination on 53 children. Blood tests and chest radiography were done, and fat impedance was measured. RESULTS: Of the 53 children, height, weight and head circumference were below the third percentile in 37(69.8%), 35(66%) and 28(52.8%) children, respectively. Body mass index, skin fold thickness and mid-arm circumference were below the third percentiles in 77.3, 50.9% and 56.6% of the children, respectively. Although serum protein levels were within normal range, anemia was detected in 31 children(58.5%). Two children showed interstitial pneumonia on chest radiograms. And HBsAg was detected in three but their liver enzymes were within normal limits. CONCLUSION: Due to the poor nutritional status of handicapped children in the asylum, the prevalence of anemia was high. Evaluation of the nutritional status and hemoglobin measurernent must be included in the routine health assessment of these children.

Paraffinoma is a well known complication of previous paraffin injection into the subcutaneous layer that presents as various conditions including firm mass formation, edema, induration, ulceration, and skin necrosis. Paraffinoma can mimic neoplasm on physical examination and imaging studies and may complicate ultrasonographic diagnoses due to typical posterior shadowing and high echogenicity. When paraffinomas involve around the thyroid gland, the diagnosis of thyroid tumors is very difficult. We present a case of thyroid cancer, the evaluation of which was complicated by the presence of cervical paraffinoma.

Single coronary artery is a rare congenital anomaly occurring in approximately 0.04% of the population. This entity can be diagnosed during life only by coronary angiography. Typical angina does not occur with single coronary artery in the absence of coexisting coronary artery disease or aortic stenosis. Among 874 patients who underwent diagnostic coronary angiography at Asan Medical Center. we have experienced a case of single coronary artery with significant atherosclerotic coronary artery disease which has been managed succesfully coronary angioplasty. We report this case of single coronary artery with a review of literature.

PURPOSE: To analyse the causes and radiologic findings in patients with mediastinitis and to evaluate theefficacy of chest CT scanning in patients with delayed diagnosis. MATERIALS AND METHODS: Seventeen patients withhistopathologically(n=15) or cliniclly diagnosed(n=2) mediastinitis were involved in this study. Eleven of theformer group underwent surgery, and in four, tube drainage was performed. All underwent chest radiography and CTscanning, and in seven patients, the causes of delayed diagnosis were analysed. RESULTS: The most common cause ofmediastinitis was esophageal rupture (n=11). Others were extension from neck abscess to the mediastinum(n=3),complications after a Benthall procedure(n=1), tuberculous lymphadenitis (n=1) and mycotic aneurysm(n=1). Patientswith esophageal rupture suffered from underlying diseases such as esophageal cancer(n=2), iatrogenic esophagealrupture(n=2), Boerhaave's syndrome(n=2), and esophagitis(n=1). In patients with neck abscess(n=3), each wassecondary to infected cystic hygroma, Ludwig angina, or deep neck infection, respectively. On chest CT, patientswith esophageal rupture(n=11) had an abscess in the posterior mediastinum; nine abscesses extended to the cervicalarea along the retropharyngeal space, and the patient with Ludwig angina had an abscess involving all compartmentsof the mediastinum. Among the total of 17 patients, diagnostic delays were found in seven, while five hadspontaneous esophageal ruptures and two suffered complications after a Benthall procedure and Tbc lymphadenitis,respectively. The causes of diagnostic delay varied. Among seven patients, pnevmonia was initially diagnosed intwo, who were treated ; one had multiorgan failure, and one was suffering from pericardial effusion and lungabscess. In three other patients, chest radiographs initially showed non-specific findings, leading to delayed CTexamination. CONCLUSION: The most common cause of mediastinitis was esophageal rupture, and in these patients,chest radiographs and clinical symptoms were sometimes not specific. CT was valuable for the detection ofmediastinitis, and for early diagnosis can be the modality of choice.

Primary small cell carcinoma of the salivary gland is a rare neoplasm that accounts for approximately 1.8% of all primary major salivary gland malignancies. Because of its rarity, it is difficult to diagnose small cell carcinoma of the parotid gland by fine needle aspiration cytology(FNAC). We experienced a case of primary small cell carcinoma of the parotid gland in a 72-year-old woman who presented with two palpable masses of the left infraauricular and ocular regions of two to three month's duration, respectively. Aspirate smears from the left infraauricular area were highly cellular on necrotic and lymphocytic background and showed individually dispersed cells or three-dimensional clusters of small cells. The tumor cells were round to oval with a very high nucleocytoplasmic ratio. Nuclei were about two times the size of lymphocytes and had uniformly dispersed but hyperchromatic to pyknotic chromatin. Nucleoli were occasionally visible but were generally inconspicuous. Numerous mitotic figures were detected. The clusters of these small tumor cells exhibited angular nuclear molding, irregular nuclear outlines, and occasionally rosette like arrangement. The tumor was confirmed by histology and immunohistochemistry.

During the long-term COVID-19 pandemic, wearing a mask is inevitable for protecting individuals from airborne infection. In this case, we found out that mask may exacerbate atopic dermatitis and it can be treated simply and effectively using silicone tape. We suggest that throughout the COVID-19 pandemic, silicone tape can be beneficial in both preventing and treating eczema caused by mask-wearing, especially in patients with atopic dermatitis.

BACKGROUND: Oxidative stress contributes to vascular diseases in patients with diabetes. As the mechanism of development and progression of diabetic vascular complications is poorly understood, this study was aimed to assess the potential role of hyperglycemia-induced oxidative stress and to determine whether the oxidative stress is a major factor in hyperglycemia-induced migration of vascular smooth muscle cells (VSMCs). METHODS: We treated primary cultured rat aortic smooth muscle cells for 72 hours with medium containing 5.5 mM D-glucose (normal glucose), 30 mM D-glucose (high glucose) or 5.5 mM D-glucose plus 24.5 mM mannitol (osmotic control). We measured the migration of VSMCs and superoxide production. Immunoblotting of PKC isozymes using phoshospecific antibodies was performed, and PKC activity was also measured. RESULTS: Migration of VSMCs incubated under high glucose condition were markedly increased compared to normal glucose condition. Treatment with diphenyleneiodonium (DPI, 10 micromol/L) and superoxide dismutase (SOD, 500 U/mL) significantly suppressed high glucose-induced migration of VSMCs. Superoxide production was significantly increased in high glucose condition and was markedly decreased after treatment with DPI and SOD. High glucose also markedly increased activity of PKC-delta isozyme. When VSMCs were treated with rottlerin or transfected with PKC-delta siRNA, nitro blue tetrazolium (NBT) staining and NAD(P)H oxidase activity were significantly attenuated in the high glucose-treated VSMCs. Furthermore, inhibition of PKC-delta markedly decreased VSMC migration by high glucose. CONCLUSION: These results suggest that high glucose-induced VSMC migration is dependent upon activation of PKC-delta, which may responsible for elevated intracellular ROS production in VSMCs, and this is mediated by NAD(P)H oxidase.
