A 65-year-old female, who suffered with a longstanding headache, was admitted to our hospital. MR imaging and digital subtraction angiography (DSA) demonstrated a vascular fat-containing mass in the right cerebellopontine angle. The lesion was surgically removed and the diagnosis of angiolipoma was established. The symptoms subsided after the operation.

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.

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.

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.

BACKGROUND AND OBJECT: Immunostimulatory CpG-oligodeoxynucleotides (ISS CpG-ODN) up-regulate the TH1-type immune response and down-regulate the TH2-type response. This study was performed to investigate the immune response changes resulting from ISS CpG-ODN on bronchial hyperrestponsiveness, eosinophilic inflammation and mucus hypersecretion in rat asthma. MATERIALS AND METHODS: 10 normal controls(NC) and 26 asthmatic rats, which were generated by ovallbumin(OVA) sensitization and challenge, were studied. The asthmatic rats were randomized into 11 asthma controls(AC) and 15 in the asthma-CpG treatment group(CpG). The CpG group was administered ISS CpG-ODN intramuscularly and the AC group was administered a placebo(0.9% NaCl)on day 15 and 20. After CpG-ODN or placebo administration, we measured the IFN-(TH1-type cytokine) and IL-4(TH2-type cytokine) levels in the bronchoalveolar lavage fluid(BALF), the specific airway resistance(sRaw), eosinophilic fraction in BALF, eosinophilic infiltration, goblet cell dysplasia and MUC5AC gene expression in the lung tissue. RESULTS: In the BALF of the CpG group, the IFN-γ concentration was significantly high and the IL-4 concentration was significantly low when compared with the AC group. Both the sRaw and eosinophilic fraction, and infiltration into the BALF and lung tissue significantly lower in the CpG group when compared with the AC group. However, little difference in goblet cell dysplasia and MUC5Ac gene expression was observed between the CpG group and the Ac group. CONCLUSION: ISS CpG-ODN decreases bronchial hyperresponsiveness and eosinophilic inflammation in the rat asthma model through the up-regulation of the TH1-type immune response with the down-regulation of the TH2-type response. However, the effect of these immune response changes on mucus hypersecretion was is not remarkable in this study.

The development of a serological marker for early diagnosis of isocyanate-induced occupational asthma (isocyanate-OA) may improve clinical outcome. Our previous proteomic study found that expression of vitamin D-binding protein (VDBP) was upregulated in the patients with isocyanate-OA. In the present study, we evaluated the clinical relevance of VDBP as a serological marker in screening for isocyanate-OA among exposed workers and its role in the pathogenesis of isocyanate-OA. Three study groups including 61 patients with isocyanate-OA (group I), 180 asymptomatic exposed controls (AECs, group II), 58 unexposed healthy controls (NCs, group III) were enrolled in this study. The baseline serum VDBP level was significantly higher in group I compared with groups II and III. The sensitivity and specificity for predicting the phenotype of isocyanate-OA with VDBP were 69% and 81%, respectively. The group I subjects with high VDBP (> or = 311 microg/ml) had significantly lower PC20 methacholine levels than did subjects with low VDBP. The in vitro studies showed that TDI suppressed the uptake of VDBP into RLE-6TN cells, which was mediated by the downregulation of megalin, an endocytic receptor of the 25-hydroxycholecalciferol-VDBP complex. Furthermore, toluene diisocyanate (TDI) increased VEGF production and secretion from this epithelial cells by suppression of 1,25-dihydroxycholecalciferol [1,25(OH)2D3] production. The findings of this study suggest that the serum VDBP level may be used as a serological marker for the detection of isocyanate-OA among workers exposed to isocyanate. The TDI-induced VEGF production/secretion was reversed by 1,25(OH)2D3 treatment, which may provide a potential therapeutic strategy for patients with isocyanate-OA.

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.

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).
