BACKGROUND: The reference list is an important part of a scientific papers. To be useful it must be accurate OBJECTIVE: The purpose of this study was to evaluate quotation accuracy in the Korean Journal of Dermatology and the Annals of Dermatology. METHODS: We randomly selected 35 references from Korean Journal of Dermatology and 35 references from Annals of Dermatology and checked them against the original articles. RESULTS: The overall rate of quotation error was 32.9%, respectively 40% in the Annals of Dermatology and 25.7% in the Korean Journal of Dermatology. CONCLUSION: This study shows that the rate of quotation errors is unacceptably high in the Korean Journal of Dermatology and the Annals of Dermatology, which significantly diminishes the value of the information of its source.

The antihypertensive effect of verapamil, a calcium channel blocker, was studied in 12 cases of essential hypertension (mean age 49, range 24-64). After 6 weeks administration (80-160mg t.i.d.), the following results were obtained : 1) Before medication, average systolic and diastolic blood pressure was 176.3/108.6mmHg. After completion of therapy, blood presure fell significantly down to 154.8/94.2mmHg (p<0.01). 2) Heart rate decreased slightly from average 74.3 per minute prior to medication to 69.3 per minute at the end of study (p<0.01). 3) Side effects, among which constipation was most common, were mild and did not compel any patient to diacontinue therapy. In conclusion, verapamil seems to be a safe and effective first-line drug for hypertension along with diuretics or beta blockers.

To assess the immunological function of toluene exposed group, the proportions of T lymphocyte, B lymphocyte, CD 4 cell, CD 8 cell, the ratio of CD4 to CD8 (CD4/CD8) in peripheral blood were measured on twenty-one toluene exposed workers and twelve healthy workers who did not have previous history of toluene exposure. In addition, to evaluate the present status of toluene exposure, urinary hippuric acid concenturations were measured in exposed group. The mean concenturation of urinary hippuric acid was 2.84 g/creatinine g in exposed group. The proportions of T lymphocyte, B lymphocyte, CD8 cell and CD4/CD8 of exposed group were slightly lower than non-exposed group except the proportion of CD4 cell which was similar in both groups. But these differences were not statistically different in both groups. The proportions of T lymphocyte and CD4 cell were significantly correlated with the length of duration in exposed group (P<0.05)

Familial benign pemphigus(Hailey-Hailey disease) is a rare hereditary dermatosis that begins in the 2nd or 3rd decade of life. The skin lesion is characterized by a localized, recurrent eruption of small vesicles on an erythematous base. During its course there are remissions and exacerbations. It seldom begins in early childhood or after the age of 50. The main treatment modalities are conservative ones. A 59-year-old woman with familial benign chronic pemphigus presented with a 10 year history of generalized pruritic recurrent skin lesions on her neck, axilla, inguinal, antecubital, and trunk area. Physical examination showed moist, macerated, fissured and scaly patches on an erythematous base in the axillae, groins, neck, antecubital, and trunk. A biopsy specimen showed extensive suprabasal separation containing acantholytic cells.

BACKGROUND: Statistical errors have been noted in a large percentage of articles appearing in medical journals. Their incidence in the Annals of Dermatology and the Korean Journal of Dermatology, however, has not been studied. OBJECTIVE: The purpose of this study was to evaluate the accuracy of statistical methods in the Annals of Dermatology and the Korean Journal of Dermatology. METHOD: Original papers using the t test in the Annals of Dermatology(AD) and in the Korean Journal of Dermatology(KJD) from January 1990 to July 1994 were analyzed for correctness of statistical methods. RESULTS: Of the 376 original papers in the period considered, 78(20.7%) presented t tests and 43(55.1%) of these also contained some errors. Of the 9 papers from the Annals of Dermatology, 4(44.4%) included at least one error. Of the 69 papers from the Korean Journal of Dermatology, 39(56.5%) included at least one error. CONCLUSION: Misuse of statistical methodology may not be uncommon in the two Korean Dermatology journals, and it would be prudent to give more attention to statistical methodology.

BACKGROUND: The reference list is an important part of a scientific article. To be useful it must be accurate. OBJECTIVE: The purpose of this study was to evaluate the accuracy of reference citations in the Korean Journal of Dermatology and the Annals of Dermatology. METHODS: We randomly selected 200 references (100 references from Korean language journals and 100 references from foreign language journals) from the Korean Journal of Dermatology and 100 references from the Annals of Dermatology and checked them against the .original articles. RESULTS: The overall rate of citation error was 32%, and errors in the title and author names of the citation were common, each occurring in about two fifths of the citation errors. CONCLUSION: This study shows that the rate of citation errors is unacceptably high in the Korean Journal of Dermatology and the Annals of Dermatology, which significantly diminishes the value of the reference list.

Generalized distinct hyperpigrnented macules developed at 2. 7 years after starting photochemotherapy(psoralen and UVA) in a 66-year-old psoriatic male patient. The histopathologic feature of this macule was characterized as a lentiginous p roliferation. The significance and long term course of PUVA lentigo are still unknown. So, we will further monitor this patient continually for melanocytic dysplasias, including melanoma.
