We report two cases of cellulitis on the saphenous venectomy scar which developed after a coronary artery bypass graft(CABG). A 68-year-old male and a 62-year-old female developed acute cellulitis in the saphenous vein donor extremity after CABG. The repeated bacterial cultures were negative in both cases. However, onychomycosis was confirmed in one patient. The intervals between CABG and the initial bout of cellulitis in the male and female patient were 10 and 22 months, respectively. Although the exact pathogenesis remains obscure, factors such as direct bacterial infection, hypersensitivity to streptococcal exotoxins, a local compromise of lymphatic and venous drainage, and fungal infection might have contributed to the development of cellulitis in these patients.

BACKGROUND: The incidence of Cutaneous malignant tumors has increased recently and they have varied in their developing patterns according to social and environmental influences. However, we have little clinical data about the cutaneous malignant tumors in the Chonnam provinee. OBJECTIVE: Our purpose was to analyze the clinical characteristics of cutaneous malignant tumors observed in the Chonnam province and to compare them with the data previously reported in Korea. METHOD: We clinically analyzed 427 cases of cutaneous malignant tumors during a 10 year period betwecn January 1987 and Oetober 1996, at the Department of Dermatology, Chonnam Univemity Hospital in Kwangju. RESULTS: 1. The average armual incidence of cutaneous malignant tumors among the total number of outpatients was 1.00+/- 0.25%. The incidence tended to increase with time from 0.90+/-0.29% in the first 5 year-period to 1.15+/-0.09% in the late 5 year-period. The increasing rate was most pronmient in basal cell carcinoma. 2. The most common tumor in the 427 patients with malignant tumor was basal cell carcinoma (52.5%), followed by squamous cell carcinoma (19.9%), malignant melanoma (13.3%), metastatic carcinoma (3.7%), malignant lymphoma (2.3%). 3. The mean age of onset was 60.7+/-16.0 years old (male; 59.6+/-15.0, female; 61.9+/-17.1) in the in the group as a whole; 63.9 in BCC, 63.3 in SCC and 55.8 in malignant melanoma. The ratio of men to women was 1.14:l. 4. The most common site of a11 malignant tumors was the head and neck (64.6%), where 89.3% of BCC, 58.8% of SCC, and 15.8% of malignant melanoma developed. The next common site was the lower exlremities and feet (15.7%) followed by the trunk (7,7%), and upper extremities and hands (7.3%).

Nevus sebaceus of Jadassohn has been referred to as a organoid nevus that classically evolves through three stages and may be associated with a range of skin tumors, and of these, syringocystadenoma papilliferum and basal cell carcinoma have been commonly reported to occur. The occurrence of keratoacanthoma is a very rare event in nevus sebaceus. Herein we report on a 23-year-old man with nevus sebaceus of the cheek. He represents a keratoacanthoma arising within nevus sebaceus.

PURPOSE: Transglutaminase 4 (TGase 4) belongs to a family of enzymes that catalyzes the post-translational modification of proteins. In an attempt to establish its physiological function(s), the distribution of TGase 4 expression in the human eye was determined. METHODS: Ocular tissues obtained from five human whole eyeball postmortem (40(+1) weeks at gestation age, 2 months, 48, 66, 76 years) were stained with monoclonal antibodies against human TGase 4 using indirect immunohistochemical method. RESULTS: TGase 4 was found in the lacrimal glands, corneal epithelium and endothelium, conjunctival epithelium, lens epithelium, retina (inner segment of photoreceptor, external limiting membrane, outer plexiform layer, inner plexiform layer, retinal nerve fiber layer and internal limiting membrane), iris, ciliary muscle, ciliary nonpigmented epithelium and trabecular meshwork. Endothelium of blood vessels in all ocular tissues was also stained. Conjunctival stroma, choroid, anterior tenon's capsule were faintly stained. No evidence of immunostaining for TGase 4 was found in the corneal stroma, iris stroma, lens nucleus, ciliary process, sclera, extraocular muscle and optic nerve. CONCLUSIONS: The expression pattern of TGase 4 was different from those of other TGase isoforms in the human eye. This result may be helpful in further investigation of the role of TGase 4 in the ocular tissue.

Herpes zoster is an uncommon disease in children, especially in healthy children. The clinical studies and observations of herpes zoster has been focused to children with hemato-oncologic diseases or immuno-compromised conditions. Recently the association of herpes zoster after varicella vaccine (Oka strain) immunization has been concerned and some cases of normal children after varicella vaccination have been reported. We experienced two cases of herpes zoster in healthy children after varicella vaccination.

OBJECTIVE: There are few studies of osteoporotic burst fractures with spinal canal compromise that were treated with kyphoplasty. The purpose of this study was to assess the efficacy and the safety of kyphoplasty for the treatment of thoracolumbar spine osteoporotic burst fractures without neurological deficits and to investigate predictors that can improve the effectiveness of this treatment. METHODS: From October 2004 until December 2010, 79 osteoporotic burst fracture patients with asymptomatic spinal canal compromise were treated by kyphoplasty. Kyphoplasty involved injecting polymethylmethacrylate (PMMA) from the anterior one-third of the vertebral body into the posterior one-third of the vertebral body. PMMA powder and liquid were mixed in a ratio of 1:3 at 21-23degrees C. Preoperative and postoperative visual analog scores (VAS), kyphotic angles, the heights of the vertebral body, and the degrees of spinal canal compromise were analyzed. The relationships between the factors and the VAS difference between the preoperative and postoperative states were analyzed. RESULTS: The mean postoperative VAS, the postoperative kyphotic angle, the vertebral body height measurement from the anterior and the middle of the body were significantly improved after kyphoplasty (p<0.05). Postoperatively, the mean VAS was restored from 7.35 to 2.11, the postoperative kyphotic angle was restored from 18.21degrees to 12.08degrees, the vertebral body height measurement from the anterior of the body was from 18.56mm to 23.54mm and the middle of the body was from 24.81mm to 27.90mm. Among the variables, only the duration of symptoms before surgical treatment was implicated as a factor in the outcome (p<0.01). CONCLUSION: Kyphoplasty is a very effective and safe therapeutic modality for the treatment of osteoporotic burst fractures without neurological deficits. The standardization of this procedure helps to avoid complications. In the acute stages, early treatment is more effective for the reduction of pain. Further investigation is warranted in order to assess the effectiveness of early surgery in improving outcome.

BACKGROUND: Protooncogene, bcl-2 is known to inhibit, apoptosis induced by various stimuli. Its expression has been reported in various fetal and adult tissues, and also in tumors of neural origin. OBJECTIVE: The purpose of this study was to evaluate the expression of bcl-2 in a skin tumor of neuroectodermal origin and to estimate whether this expression was useful in the different,ial diagnosis of tumors of neural origin or not. METHOD: Immunohistochemical stains by the LSAB(labelled streptavidin biotin) method for bcl-2 protein were performed in normal special nerve end-organs and a skin tumor of neural origin. RESULTS: The immunohistochemical findings revealed strong positive results in Meissners corpuscles, but weak week positive results in Vater-Pacini corpuscles. There were also strong positive results in neurilernmomas which were mostly composed of Schwann cells, but results were mostly negative in neurofibromas and neurofibrosarcomas which were composed primarily of endoneurial fibroblasts of mesodermal origin except a few cells of Schwann cell origin. Benign granular cell tumors arising from Schwann cells, and Merkel cell carcinoma known to arise from the Merkel cells of neural crest origin showed strong positive reactions. CONCLUSION: The strong expression of bcl-2 protein exclusively in the tumor of neuroectodermal origin suggests a useful indicator for the differential diagnosis of skin tumors of neural origin.

Elevations of serum PSA concentrations have been widely reported due to prostatic cancer, but other causes haute not been formally characterized or quantified. So that, we evaluated the causes of elevated serum PSA concentrations in men whose prostate biopsy showed no cancer. The effects of prostate volume, inflammation, echogenecity on ultrasound and calculi were examined in 43 men that serum PSA concentrations greater than 4.0 ng/ml with negative biopsy. These men were compared with 16 men who had suspicious rectal examinations, negative biopsy and serum PSA concentrations of 4.0 ng/ml. or less. Prostate volume (22.5%, p<0.005) and inflammation (3%, p<.05) were significantly associated with elevated serum PSA concentrations (>4.0 ng/ml) than control group (< or = 4.0 ng/ml) and age echogenecity on ultrasound and calculi were statistically less significant (p> or =0.05). In summary, prostate volume and inflammation were the most important factors contributing to increase serum PSA concentration in men that clinically undetectable prostatic cancer.
