A 28-year-old woman had a 13-month history of skin-colored, well-circumscribed, hyperkeratotic plaques on both heels. Histological examination showed hyperkeratosis and acanthosis in the epidermis. Special stain for elastic tissue revealed marked fragmentation, diminution and thickening of elastic fibers in the dermis. We report a rare case with the lesions of acrokeratoelastoidosis on both heels.

BACKGROUND: Stellate ganglion block (SGB) is known to increase blood flow to the innervations area of the stellate ganglion. Near infrared spectroscopy reflects an increased blood volume and allows continuous, non-invasive, and bedside monitoring of regional cerebral oxygen saturation (rSO2). We investigated the influence of SGB on bilateral cerebral oxygenation using a near infrared spectroscopy. METHODS: SGB was performed on 30 patients with 1% lidocaine 10 ml using a paratracheal technique at the C6 level and confirmed by the presence of Horner's syndrome. The blood pressure (BP), heart rate (HR) and rSO2 were measured before SGB and 5, 10, 15 and 20 minutes after SGB. Tympanic temperature of each ear was measured prior to SGB and 20 minutes after SGB. RESULTS: The increments of the rSO2 on the block side from the baseline were statistically significant at 5, 10, 15 and 20 minutes. The rSO2 on the non-block side compared with the baseline, however, decreased at 15 and 20 minutes. The difference between the block and the non-block sides was significant at 15 and 20 minutes. The BP at 10, 15 and 20 minutes was increased and the HR was increased at 10 and 15 minutes. CONCLUSIONS: We observed an increment of the rSO2 on the block side from the baseline; however, the rSO2 on the non-block side decreased.

A healthy 18-year-old woman presented with an asymptomatic tiny papular eruption on the hands, forearms, legs and trunk. A skin biopsy from the left forearm revealed a typical lichen nitidus lesion associated with an adjacent transepidermal perforating lesion. We report a case of perforating lichen nitidus, and briefly review the relevant literature of perforating lichen nitidus.

BACKGROUND: Squamous cell carcinoma(SCC) on sun-damaged skin is a malignant neoplasm that evolves from its inception as squamous cell carcinoma in situ, which is commonly referred to as an actinic keratosis(AK) or Bowen's disease(BD). OBJECTIVE: The purpose of this study was to determine whether there is a significant association between cutaneous SCC on sun-damaged skin and AK or BD in Korean. METHODS: A total of 50 Korean patients with SCC on sun-damaged skin was enrolled in this study. The hospital charts and histopathological slides of the patients with SCC on sun-damaged skin diagnosed at Chungbuk National University Hospital from July 1, 1991 to March 1, 2001 were reviewed. We investigated the incidence of actinic keratosis and Bowen's disease and histopathological characteristics of actinic keratosis at the periphery or within the confines of cutaneous SCC. RESULTS: Of the 50 cutaneous SCC cases on sun-damaged skin reviewed, 96.0% (48 out of 50) were found to have concomitant AK or BD at the periphery or within the confines of cutaneous SCC. The most common histopathological subtype of accompanying AK in the cutaneous SCC was the hypertrophic type. CONCLUSION: The 96.0% prevalence of concomitant AK or BD and SCC in our biopsy population suggests a strong correlation between these lesions.

OBJECTIVES: It is difficult to carry and set up a large numbers of computers when computerized neurobehavioral tests are performed to many subjects. There are difficulties in mobilizing and resetting desktop computers and so, the use of desktop computers will decrease due to the recent increasing popularity of laptop computers. However, it is essential that there is no difference between the tests performed on a laptop and on a desktop computer. This study was conducted to estimate the effect that the type of computer has on computerized neurobehavioral performance tests. METHODS: Three types of computers were applied. Type 1 was a normal laptop computer. Type 2 was a laptop computer that was remodeled and equipped with a modified keyboard. A common desktop computer with a remodeled keyboard as type 3. The computerized tests included Simple Reaction Time, Choice Reaction Time, Symbol Digit, and Finger Tapping Speed. A total of 60 subjects were examined by the identical tester in the same testing conditions. The computers were randomly allocated, which were used in the test and let examinees take tests with the separate computers. RESULTS: There were no significant differences among the computers for the results of the Simple Reaction Time and Finger Tapping Speed tests. The mean reaction time, error number of Choice Reaction Time and mean reaction time, correct mean reaction time, error number of Symbol Digit produced significantly different results among the three types of computers. CONCLUSION: This study indicates that with only a laptop computer the Simple Reaction Time test using the space bar was useful. But with the laptop computer, the Choice Reaction Time test using the four-direction key and the Symbol Digit test using the upper end number key were unsuitable. The keyboard should be developed further for the Choice Reaction Time and Symbol Digit tests. Among the three computers, we recommend the use of the desktop computer with the remodeled keyboard which the examinees are familiar with and the laptop computer with the remodeled keyboard.

Lues maligna (malignant syphilis), also called noduloulcerative syphilis, is a kind of cutaneous secondary syphilis, which presents virulent clinical features and is frequently associated with an immunosuppressed state. Though there are many possible debilitative diseases, it has recently been more frequently presented in the human immunodeficiency virus (HIV)-infected patients. Other causes are diabetes and chronic alcoholism. Prompt diagnosis and early treatment can result in a desirable recovery and prevent spread of the disease. We report two cases of lues maligna associated with the underlying diseases of HIV-infection and diabetes. The skin lesions in these cases showed favorable results after treatment with benzathine penicillin.
