BACKGROUND: Seborrheic dermatitis (SD) is a chronic, relapsing inflammatory disease, mainly affecting the scalp and face. The pathogenesis of SD has been not fully understood yet, but may be related to the skin colonization of Malassezia species, lipophilic yeasts. Phototherapy with light emitting diode (LED) device has been become a new therapeutic modality for some skin diseases such as acne. OBJECTIVE: To evaluate effectiveness and safety of phototherapy with home-use LED in the treatment of patients with SD of the scalp. METHODS: Eight patients with mild-to-moderate SD of the scalp participated. The patients used a home-use LED device combined 395 nm blue light with 660 nm red light for 6~7 min twice daily for 8 weeks. Patients' assessments were made by clinical findings including erythema (0~15), scales (0~15), itching (0~10), and lesional extent (0~15). And clinical photographs were taken at 0, 2, 4 and 8 weeks, respectively. RESULTS: At 8 weeks after LED treatment, erythema (7.75 to 5.13, p=0.018), scales (7.38 to 4.13, p=0.017), itching (6 to 3, p=0.011) and lesional extent (8.25 to 5.25, p=0.017) were significantly decreased, respectively. Satisfactory scores were also relatively high (mean 8.13 of 10). No severe adverse reaction was reported, excepting hair dryness (n=1) and brief stinging sense (n=1). CONCLUSION: Home-use LED was effective and safe in the treatment of SD of the scalp. These results suggest the LED device might be an adjuvant therapeutic tool in the treatment of Malassezia species associated diseases such as dandruff and SD. Further long-term and large-scale studies are required to assess the efficacy and safety of home-use LED.

STUDY DESIGN: This retrospective study is to confirm the diagnostic accuracy of percutaneous needle biopsy of vertebral lesions. OBJECTIVES: To evaluate the diagnostic accuracy of percutaneous needle biopsy and the clinical and pathological correlation of vertebral lesions. SUMMARY OF LITERATURE REVIEW: A review of previous articles showed that the diagnostic accuracy of percutaneous needle biopsy of vertebral lesions was between 77-94%. The greatest accuracy was achieved in diagnosis of metastatic disease or infection. MATERIALS AND METHODS: We performed 22 percutaneous needle biopsies in twenty vertebral bodies and two posterior elements under the CT guidance. All biopsies were performed with a 16-gauge Osty-cut bone biopsy needle. There were 1 cervical, 8 thoracic and 13 lumbar biopsies. Transpedicular approach was performed on 13 patients and paraspinal approach on 7 patients. There were 8 malignancies, 9 infections, 2 benign tumors, 2 compression fractures and 1 butterfly vertebra. RESULTS: An accurate diagnosis was made in 18 cases(81.8%) of all cases. Two of the 22 specimens were blood clots and two specimens of tuberculous spondylitis were insufficient for definite diagnosis. Bacteriological studies revealed a causative agent in 43% of pyogenic spondylitis. Histologic diagnosis confirming the clinical suspicion was obtained in 16(80%) of the 20 positive cases. There was no complication. CONCLUSION: Percutaneous needle biopsy under the CT guidance is a safe and accurate method for obtaining a diagnosis of vertebral lesions such as osteolytic lesion and infection.

Eccrine porocarcinoma is a rare cutaneous neoplasm arising from the eccrine sweat duct. It may arise de novo or evolve from a pre-existing poroma or hidroacanthoma simplex. The pigmented variant of porocarcinoma is very rare, and its heavy pigmentation can lead to misdiagnosis of seborrheic keratosis or melanoma. An 82-year-old male patient presented with a painful, brown-to-black colored plaque measuring 4x4.5 cm with a central pedunculated nodule that measured 2.5x2 cm on his right posterior thigh. A small, pigmented papule had developed 10 years prior and had gradually increased in size. Histopathologic examination of the nodule revealed lobulated tumor islands composed of atypical basaloid cells in the periphery, eosinophilic squamous cells in the center, and pigmented dendritic cells scattered throughout nests of the tumor. Carcinoembryonic antigen and epithelial membrane antigen were expressed in the tumor cells and the dendritic cells stained positive for S-100 and HMB45. Histopathologic findings from the plaque showed many pigmented nests embedded within the epidermis that were composed of small, polygonal, pigmented basaloid cells. Pigmented eccrine porocarcinoma arising from pigmented hidroacanthoma simplex was diagnosed clinically and histopathologically. The tumor was completely excised. We report a case of pigmented porocarcinoma, which should be included among clinically important differential diagnoses apart from melanoma.

Anastomotic leakage following rectal resection is a serious and fearful complication, and may cause presacral abscess and/or peritonitis. To our knowledge, massive hematochezia secondary to presacral abscess caused by anastomotic leakage has not yet been reported in the literature. We observed this rare and life-threatening complication in three patients who were successfully treated with a simple but effective transanal gauze packing technique.

Renal cell carcinoma involves the inferior vena cava (IVC) in approximately 5-10% of the patients. Presently surgical extirpation is the only form of therapy that can result in cure. Circulatory arrest with cardiopulmonary bypass is an operative technique that recently has been used to assist in resection of tumors that extend into the vena cava above the level of hepatic veins. We performed removal of tumor thrombi of IVC in 4 patients. All of them who had the renal cell carcinormas with infrahepatic vena caval extension were performed by standard surgical technique without cardiopulmonary bypass. But in one patient, inferior vena caval thrombectomy was done using circulatory arrest because of the recurred extension of the tumor thrombi within the vena cava above the insertion of the hepatic vein. All patients were recovered without any significant problems.

PURPOSE: To evaluate the utility of quantification of coronary artery calcification using spiral CT. MATERIALS AND METHODS: Spiral CT scans of the heart were obtained in 25 patients with coronary artery disease diagnosed by coronary angiography and in six controls without coronary artery disease. Spiral CT was performedwith 3 mm collimation at 3 mm/sec table speed and the obtained volume data of the heart was reconstructed at 2 mm intervals. Total calcium scores of the 30 contiguous slices of the proximal coronary artery were calculated basedon the areas and peak density. Two groups were compared for total scores and sensitivity, and specificity and positive predictive values were calculated. RESULTS: The number of subjects with coronary calcification(totalcalcium score>0) detected by spiral CT were 20(80%) of 25 with coronary artery disease and 2(33%) of 6 without coronary artery disease. The sensitivity, specificity, and positive predictive values were 80%, 67% and 91% respectively. Sensitivity was 64%, specificity was 80% in patients aged < or =60. Sensitivity was 76% and specificity was 83%(total calcium score 10). CONCLUSION: Quantification of coronary artery calcification using spiral CT haslow specificity in the older group and low sensitivity in the younger group ; the procedure is therefore may notbe useful as a non invase screening test to predict the prescence of coronary artery disease. In the younger group, however, a cardiac workup is strongly indicated if calcification is present.

From Jan. 1991 to Apr. 1996, 99 cases of microsurgical tubal reversal were performed in the Department of Obstetrics and Gynecology, Chunchon Sacred Heart Hospital of Hallym University. 80 cases among them were followed up over 1 year postoperatively. The results were as follows : 1. The mean age of total 99 women was 32.5 years(24~42 years), and the average interval between tubal sterilization and tubal reversal was 7.2 years(1~17 years). 2. The methods of sterilization were laparoscopic fallope ring in 59 cases(59.6 %), laparoscopic electrocautery in 30 cases(30.3 %), tubal ligation during cesarean section in 9 cases(9.1 %) and minilap in 1 case. 3. The most common reason for tubal reversal was remarriage(61 case, 61.6 %) and the next was desire for son(16 cases, 16.2 %). 4. 80 cases(81 %) among the total 99 women were followed up over 1 year postoperatively. Intrauterine pregnancy was documented in 59 cases(73.7 %), 53 viable fetuses and 6 spontaneous abortions. Ectopic pregnancy was noted in 3 cases(3.8 %). 5. Pregnancy rates according to maternal age were as follows ; 88.9 % in less than 30 years, 70.3 % in 30~34 years, 71.4 % in 35~39 years. Two normal pregnancies were resulted from 4 women over 39 years. 6. Pregnancy rates according to the method of sterilization were as follows ; 78 % in fallope ring, 89 % in tubal ligation during cesarean section, 55 % in electrocautery. The statistical differences between each groups were not significant(p = 0.053). 7. Pregnancy rates according to the site of anastomosis were as follows ; 81.4 % in isthmicisthmic, 67.1 % in isthmic-ampulla. There was significant statistical difference between them(p = 0.011). 8. Pregnancy rates according to the postoperative tubal length were as follows ; 60 % in less than 4cm, 66 % in 4~6 cm, 95.4 % in more than 6cm(p = 0.024). 9. Among the 59 pregnant women, 38 pregnancies(65.4 %) were resulted within six months after surgery, 48(82.3 %) within one year, and 55(94.2 %) within 2 years. 10. Pregnancy rates according to the interval from tubal sterilization to tubal reversal were as follows ; 89.6 % in less than 5years of interval, 74.5 % in 5~10 years, 44.4 % in 11~15 years(p = 0.230).

We encountered one case of Chinese Herb Nephropathy in Korea. But clinical feature of our case was different from those of CHN in Belgium. The purpose of this case report was clarified the features of CHN in Asia. The subjects consisted of a patient diagnosed as interstitial nephritis in Hanyang University Hospital and of those reported in the literature in Asia and Belgium. We investigated the clinical and histological features of CHN patients in Asia and compared them with the Belgian cases. The remarkable differences were as follows; (1) relatively high prevalence in males compared with Belgian cases, (2) digestion with multiple object and mode in Asia, (3) Most of renal failure in Asia were improved or were in stable status. (4) Fanconi's syndrome was found in most cases of Asia. In conclusion, CHN in Asia has some characteristics distinguished from Belgian Chinese Hreb Nephropathy. These findings could indicate that susceptibility to aristolochic acid may be different among races. Furthermore, it is likely that different components of AA could cause different features, that the amount of ingested AA, mode in digestion, or interaction with other components except nephrotoxic agent such as AA might reflect clinical pictures. Other hypothesis may be some other toxic substances affecting the clinical findings although they are not identified at present. Further studies must be undertaken to clarify these differences.
