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.

A case of the recurrent neurilemmoma of vagus nerve in the neck is presented. It was located in the upper third of the right lateral neck. The patient was presented with hoarseness and monoparesis of the right arm. The tumor was composed of large cystic portion and solid nodule in the right carotid fossa. Since total surgical removal of the tumor could cause functional deterioration of the involved vagus nerve, it was removed by means of intracapsular enucleation. Postoperatively, the monoparesis of the right arm was disappeared with preservation of vagus nerve function. It would appear that an intracapsular enucleation may be advisible in some cases of neurilemmomas of the cervical vagus nerve to maintain the function of the involved vagus nerve.

The usefulness of DNA databases is well known. In Korea, many cases have been solved since the establishment of DNA databases in 2010. DNA profiles obtained from criminal evidence are analyzed and are kept in databases, and matching profile is searched. On the matching occasion, DNA databases can provide some investigative information. Close family members, for example father, son or brother, share more alleles than unrelated people. This genetic closeness can be searched using the so called familial searching, and many successful cases have been reported. Management of DNA databases including familial searching needs continuous monitoring and control, especially from ethical view points. Many different views for familial searching have been presented, and each country running DNA databases has their own different policies. We present the utility, approaches and different policies of familial searching as well as arguments for and against familial searching. We also suggest that our appropriate guidelines be mandatory and a proper administrative process be prepared for the start of familial searching.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea. Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers, 2 VNTRs, 36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods and the profiling data were described.

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.

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).
