Irritant skin reactions can be evaluated by several techniques. Using different scores for the degree of erythema, edema, scaling and fissuring is the time-honored approach but implies t,he disadventagrs of lacking objectivity and pararretric properties. This paper describes the objective nteasurement of irritant. skin responses to various concentrations of Sodium Lauryl Sulfate(SLS) and Ethanol by a color reflectance meter(Chroma Meter) and compares with visual scoring The results are summarized as follows : 1. Pretreatment assessments by a Chroma Meter on normal forearm area showed an average score of 7.70+1.53 for Chroma Meter value a*(rediies:; score). 2. Skin responses to SLS in various concentrations of 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 7.5% under occlusion for 24 hours were assessed by visual scoring system. They are measured 0.56+1.10, 0.74+1.29, 1.19 1.36, 2.11+1.69, 2.19+1.91, 2.56+1.50 2.81+2.16 respectively. 3. Skin responses to SLS in various concentrations of 0.5, 1.0, 2.0, 3.0, 4.0, 5.0, 7.5% under occlusion for 24 hour were assessed by a Chroma Meter valu a*(redness score). They are measured 8.29+1.98, 8.37+2.47, 9.31+2.27, 10.34+2.97, 10.35+3.18, 10.51+2.47, 11.61+3.45 respectively. 4. Skin responses to Ethanol in various concentrations were nearly negligible. 5. We have demonstrated there is a highly significant correlation between skin redness measured by the Chroma Meter and visually assessed erypthma(p<0.0001). It yields reproducible, objective, quantitative measurements of iryhema that parallel the subjective visual assessments.

A case of eosinophilic pustular folliculitis in a 46-year-old woman is presented. The patient showed repeatedly developed erythematous, indurated plaque studded with srnall yellowish pustules on flush area of the left cheek with blood eosinophilia and biopsy revealed histopathological findings of eosinophilic pustular folliculitis. The patient responded well to systemic administration of corticosteroid and dapsone.

Color developers(CD) have been noted to produce lichen planus like eruption as well as eczematous contact dermatitis. The chemicals involved are derivatives of paraphenylenediamine or aniline, i. e., Kodak CD 2, Kodak CD 3, Agfa TSS. We report a 28-year-old male who showed a feature of lichenoid contact dermatitis after exposure to color developer. Patch test revealed positive reactions to CD2, CD3 and CD4. Skin biopsy from a patch site showed lichen planus-like tissue reaction.

Warts, or verrucae, are benign epithelial proliferations of the skin and mucosa caused by infection with human papillomaviruses (HPV). It is now recognized that there are many different HPV types. Especially type3 is most frequently observed in flat wart. Other types, such as type2, 10, 14, 27, 28, 29, 38, and 41 are rarely encounted in flat wart. We describe here a simple and economic method for detection and identification of epidermodysplasia verruciformis-associated HPV. The method is based on polymerase chain reaction (PCR) amplification and restriction analysis. The method has been developed with cloned HPV DNA and DNA from clinical samples. Clinical samples are from either frozen tissue or paraffin-embedded tissue. Genomic fragments were obtained from two different HPV types (3 and 10). The amplification fragments were identified by a form of miniature fingerprinting, with a set of restriction enzymes that gave a unique digestion pattern for each HPV type. We have tested 74 clinical samples. Only type3 among these clinical samples is detected, and one sample is involved in neither type3 nor type10.

OBJECTIVE: Traumatic atlanto-occipital dislocation (AOD) results from high energy trauma and is an uncommon and usually fatal injury due to an injury to the cervicomedullary junction. Recently, improved prehospital management, early diagnosis and effective treatment led to increasing reports of survival. This study of patients with AOD initial imaging modalities recognizes the clinical features and diagnostic considerations for a quick diagnosis. METHODS: In this article, five survived adult patients with traumatic AOD are presented and retrospectively reviewed. Diagnosis was made by lateral cervical spine x-ray, cervical computed tomography (CT), or magnetic resonance imaging(MRI). Treatment consisted of early immobilization, respiratory support, and subsequent occipitocervical fusion. RESULTS: Four patients were male and the other one was female. Three were diagnosed early and the others were delayed in confirmations. One was type I AOD and four were type II AOD. All patients were applied occipitocervical fusion. Two cases were worse; neurological states and the other three that showed no change. Lateral X-ray film of all patients in the prevertebral soft tissue swelling at the C2 level was noted. The mean thickness of prevertebral soft tissue C2 level was 17.88 mm(15.18 to 20.17mm). Two were in the normal range of dens-basion index(DBI), three showed abnormalities, and Power's ratio was abnormal in 3 patients. CONCLUSION: As for damages caused by a strong external force in patients with severe prevertebral soft tissue swelling at C2 level abnormaly, the doctor determines whether more should be carefully AOD and considers 3D CT or MRI to confirm AOD in these patients.

OBJECTIVE: The objectives of the present study were to characterize the natural course of initially non-operated traumatic acute subdural hematoma (ASDH) and to identify the risk factors of hematoma progression. METHODS: Retrospective analysis was performed using sequential computed tomography (CT) images maintained in a prospective observational database containing 177 ASDH cases treated from 2005 to 2011. Patients were allocated to four groups as followings; 136 (76.8%) patients to the spontaneous resolution group, 12 (6.8%) who underwent operation between 4 hours and 7 days to the rapid worsening group (RWG), 24 (13.6%) who experienced an increase of hematoma and that underwent operation between 7 and 28 days to the subacute worsening group (SWG), and 5 (2.8%) who developed delayed aggravation requiring surgery from one month after onset to the delayed worsening group (DWG). Groups were compared with respect to various factors. RESULTS: No significant intergroup difference was found with respect to age, mechanism of injury, or initial Glasgow Coma Scale. The presence of combined cerebral contusion or subarachnoid hemorrhage was found to be a significant prognostic factor. Regarding CT findings, mixed density was common in the RWG and the SWG. Midline shifting, hematoma thickness, and numbers of CT slices containing hematoma were significant prognostic factors of the RWG and the SWG. Brain atrophy was more severe in the SWG and the DWG. CONCLUSION: A large proportion of initially non-operated ASDHs worsen in the acute or subacute phase. Patients with risk factors should be monitored carefully for progression by repeat CT imaging.
