BACKGROUND: Herpes zoster(HZ), caused by reactivation of latent varicella-zoster virus, is manifested by dermatomal distribution of skin rashes, acute pain and post-herpetic neuralgia by pathologic involvement of the sensory ganglia. Low-energy laser(LEL) deliver a small amount of energy without elevation of the tissue temperature. LEL is reported to have various biologic effects such as anti-inflammatory, analgesic, regenerative, antiallergic, immunocorrective, and antibacterial effects. OBJECTIVE: We attempted to evaluate the therapeutic effect of LEL on an acute phase of HZ. METHODS: A total of 60 patients with acute HZ were enrolled in the study. The control group(30 patients) received medications including analgesics, antihistamine, and topical care without LEL irradiation. The experimental group(30 patients) were irradiated with LEL daily for 7 days in addition to the same kinds of medications for the control group. The efficacy of LEL irradiation for HZ was assessed by analyzing changes in skin rashes, pain scores, and postherpetic neuralgia.

A 4-year-old boy has had a solitary sclerotic depressed plaque on the right anterior chest since birth. The histopathologic findings are consistent with morphea profunda: thickening, hyalinization, and homogenization of collagen bundles in the dermis and subcutaneous tissues, admixture with a prominent lymphocytic and plasma cell infiltrate, and sweat glands en-trapped between the thickened collagen bundles. We report a case of congenital solitary morphea profunda.

STUDY DESIGN: Retrospective study OBJECTIVES: The purpose of this study was to analyze patients who developed deep wound infections after receiving PLIF for degenerative lumbar disease, and report the treatment outcomes. SUMMARY OF LITERATURE REVIEW: Few studies have examined deep wound infections after PLIF, and there is some controversy regarding whether screws or cages need to be removed to treat infections. MATERIALS AND METHODS: Nine cases(spinal stenosis 6, spondylolisthesis 3) developed a deep wound infection after PLIF from 2001 to 2007. The mean follow up was 48 months (24-72). The clinical results were evaluated using MacNab's criteria. RESULTS: The diagnosis of infection was made based on the clinical symptoms and signs, and inflammatory markers, such as ESR and CRP. The time to diagnosis was less than one week (2), three weeks (2), six weeks (1) and three months or more (4). Bacterial identification was performed on seven cases. MRSA was detected in one of them, and no bacteria were identified in the other six. In two of them, the infection subsided with antibiotic therapy only. In 7 cases, removal of the cage and anterior iliac strut graft was needed for infection control. In four cases, loosened screws were removed during debridement. In 2 cases, additional surgery for pseudarthrosis was required after curing the infection. CONCLUSIONS: In deep infections after PLIF, early diagnosis and bacterial identification are important for reducing the need for a later radical operation. It is recommended that blood markers of infection be measured with a short follow-up period. In a case of persistent infection against prolonged antibiotics, removal of the cage or screw is needed to treat the infection earlier.

BACKGROUND: Bentonite clay, which is a major component of mud pack, has been used for various purposes in cosmetics. Glycolic acid is known to be effective in the treatment of acne. Al-though those products are used widely, information on the mode of action and effects on the skin are little and controversial till now. OBJECTIVE: To investigate whether bentonite alone, or bentonite with glycolic acid in mixed formulation affect the stratum corneum leading to alteration on cutaneous barrier function and whether those products alter the lipid lamellae and desmosomes of corneocytes. MATERIALS AND METHODS: Mud pack-type ointment of bentonite, bentonite and 5% glycolic acid formulation, bentonite and 10% glycolic acid formulation were applied on the volar fore-arm of the five healthy men and flank skin of five 6-8 week old hairless mice. Transepidermal water loss and capacitance were measured. Electron microscopic examination after ruthenium tetroxide postfixation was performed on the flank skin of the mice. RESULTS: Transepidermal water loss(TEWL) increased immediately and normalized 4 to 6 hours later after removal of vapor permeable membrane in both mouse and human. Capacitance did not show any evidence of change in the water content of the stratum corneum. Electron microscopic examination revealed that lipid lamellae and desmosome of corneocytes were not de-graded, but lamellar body secretion and partially electron-lucent material was-increased in 10% glycolic acid and bentonite mixture-treated area. CONCLUSION: Barrier function of stratum corneum is not disturbed by bentonite and glycolic acid formulations at the concentration used. Barrier structures are not disrupted, but lamellar body secretion and partially electron-lucent material was increased by bentonite and glycolic acid formulations at higher concentration.

OBJECTIVE: To evaluate the efficiency of the measurement of fetal nuchal translucency (FNT) and ductus venosus Doppler examination (DV Doppler) as a screening tool for chromosomal abnormalities. METHODS: FNT measurement and DV Doppler wereperformed in 950 pregnancies between 11(+0)~13(+6) weeks' gestation. Chromosomal analysis was done when FNT was more than 3 mm and DV Doppler showed absent flow or reversed flow. The numbers of cases with increased FNT and abnormal DV Doppler were counted in the groups of abnormal and normal karyotype. RESULTS: Data were available in 912 pregnancies. 11 pregnancies showed abnormal karyotype (1.2%). In the 11 cases with abnormal karyotype,increased FNT was found in 8 cases with 72.7% sensitivity and abnormal DV Doppler was found in 5 cases with 45.4% sensitivity. In the 901 cases withnormal karyotype, increased FNT was found in 33 cases with 96.3% specificity and abnormal DV Doppler was found in 12 cases with 98.7% specificity. Positive predictive value was 19.5% in cases of increased FNT, 29.4% in cases of abnormal DV Doppler, and 44.4% in cases of increased FNT and abnormal DV Doppler both. CONCLUSION: There is no improvement in general screening for chromosomal abnormalities when FNT measurement and DV Doppler were performed together. But better specificity and positive predictive value for chromosomal abnormalities were found.

BACKGROUND: Topical irritants disrupt the cutaneous permeability barrier through the removal of stratum comeum lipids. This perturbation of barrier integrity stimulates a variety of homeostatic repair responses that ultimately result in the normalization of bamer function. Object To measure the effect of desoxymethasone ointment, vaseline and hydrobase on the barrier recovery of benzalkonium chloride (BKC) imtated skin. MATERIALS AND METHODS: The left flank skin of 2-3 monthold hairless mice was treated with BKC and then desoxymethasone ointment, vaseline and hydrobase were applied. Transepidermal water loss (TEWL) was checked after 0, 3, 6, 9, 12, 15, 18, 21 and 24 hours. Electron microscopic examination was performed after 3 and 24 hours after desoxymethasone, vaseline and hydrobase had been applied. RESULTS: The recovery of TEWL was most prominantly observed in the desoxymethasone ointment treated group followed by vaseline and hydrobase. Electron microscopic examination using ruthenium tetroxide fixation revealed that secretion and numbers of lamellar bodies and complete formatice of lipid bilayers were most prominent at desoxymethasone ointment and vaseline treated group. CONCLUSION: Desoxymethasone ointment, vaseline and hydrobase can be good agents in improving bamer recovery after exposure to irritant material.
