PURPOSE: Newborn infants with diarrhea, metabolic acidosis and dehydration may develop methemoglobinemia without exposure to oxidizing agents. This study was undertaken to investigate clinical features in the development of methemoglobinemia in newborn infants with diarrhea. METHOD: This study involved 16 newborn infants with diarrhea who were admitted to NICU at Dong San Medical Center between January 1995 and June 1996. We investigated the age of onset of methemoglobinemia, sex ratio, level of methemoglobin in the blood, feeding methods, clinical manifestations, arterial blood gas findings, the results of culture findings and the response to therapy. RESULT: 1) The age of onset was beyond the second week of life in most cases, no sex predilection was noted and formula feeding was used in all cases. 2) Methemoglobin level in the blood was 10.1-20.0% in 7 cases, 20.1-30.0% in 6 cases, 30.1-40.0% in 2 cases and above 40.1% in one case. 3) Clinical rnanifestations on admission: moderate to severe dehydration developed in all patients with diarrhea along with respiratory distress in 13 cases, cyanosis in 6 cases, fever was noted in 5 cases, vomiting in 5 cases, while 2 cases presented with abdominal distention. Combined diseases included metabolic acidosis in most cases (93.8%), hypokalemia in 6, failure to thrive in 3, chronic diarrhea in 2, hyponatremia in 2, necrotizing enterocolitis in 1 and hepatitis was found in one case. 4) In all cases, there were no pathogenic organisms found in either blood or urine cultures along with similar negative findings in stool cultures, and Rotazyme test results using ELISA method were negative. 5) Rehydration and correction of acidosis with sodium bicarbonate was accomplished in all patients and 11 cases with greater than 15% methemoglobin were treated with methylene blue, 2mg/kg as a 1% solution in normal saline. Response to methylene blue was indicated in 1 to 2 hours in all cases although there was a reoccurrence of methemoglobinemia after an initial response in 2 cases, they both responded favorably with retreatment with methylene blue. CONCLUSION: In all newborn infant with diarrhea, dehydration and metabolic acidosis, screening tests for early diagnosis of methemoglobinemia should be considered with prompt fluid replacement therapy.

A 45-year-old female noticed a pruritic erythematous firm pea sized nodule on the left earlobe about 18 years prior to uisiting our clinic. The lesion has increased in size gradually and involved the whole earlobe. On March 1988, the earlobe became enlarged with extreme pruritus, and showed a tendency of easy bleeding by scratch. The skin lesions consisted of multiple pea to bean sized, shiny dusky red colored, moderate firm nodules or tumors with edema on the left. ear helix, antehelix, external auditoy meatus, and retroauricular fold. The histopathologic studies revealed vascular proliferation, presence of histiocyt.oid endothelial cells, and prominent inflammatory infiltration including large numtaer of eosinophils with fibrosis in the dermis. Hematological studies revealed eosinophilia(9%). Excision of several nodules and intralesional injection of trinmcinolon acetonide did not show complete favorable effect and treatment with carbon dioxide laser was attempted. With the patient under local anesthesia with 2% lidocaine, the lesion were treated with three t,o four passes at 25,100 second intervals with ieradiance 5W(cm. The pro- cedure was repeated until no abnormal findings could be seen in the treatment zone. Treatment with carbon dioxide Iaser on the patient obtained a satisfactory result.

Clear cell hidradenoma, generally as an eccrine sweat gland origin, is a fairly uncommon tumor and occurs as a slowly growing, usually solitary nodule. The histological patterns vary from one tumor to another and in different parts of the same tumor. We experienced three cases of clear cell hidradenoma which were diagnosed by the histopathologic examination of the tumor mass removed by surgical excision. Clinical and histopathologic features of each case were reviewed and compared.

BACKGROUND: Although warts are known to be caused by viruses, one of their peculiarities is that they may be treated by suggestion therspy or hypnosis. This suggests that psychologic or emotional factors influence the hosts response to the virus lesions. OBJECTIVE: The purpose of the study was to analyze the role of psychologic factors in the therapeutic response of warts. METHODS: The self-concept scale test(Korean Testing Center) was done in all 61 patients with common wsrts before the cryot.herapy from September 1991 to June 1993. Clinical follow-up data were obtained on 50 patients after 2 months, and then were evaluated usir g the self-eoncept scale in treated vs untreated group. RESULTS: 1. The overall cure rate was 56.0%, being higher in females and patients with high education, 1-3 in number of lesions and no previous treatment history as well as in those with less than 1 year of duration. 2. In the comparison of self-concept scale between treated(n=18) and untreated(n=22) groups, the treated group had remarksble results in moral ethical self, personal self and family self scores (p<0.05). Only 14 items were significantly different between two groups(p<0.05 by Wilcoxon rank sum test). 3. Patients of 20 years or more showed a high cure rate(67.79%, p<0.05 by t-test) and demonstrated significance in total positive self score and its self identity, and satisfaction, self behavior, physical self, moral ethical self and family self scores(p<0.05, by t-test). CONCLUSION: The self-cancept significantly related to the positive aersonality, harmonious family, stable self-esteem and high normal ethics, may influence at least the therapy to the warts in the treated patients in contradistintion to the untreated ones.

The mechanism of cytolysis by complement attack of nucleated cells(NC) is of special interest in comparison to that of red blood cells. It is known that NC death by membrane attack comples, C5b-9, is caused by many factors, i.e., efficiency of complex assembly, activation of intrinsic metabolic pathway by signal transduction, cytotoxic effect of the channel itself and natural repair ability. These factors suggest that colloid osmotic lysis, known in red blood cells, does not fully explain the complement-mediated cell death of NC. In this study, the authors investigated correlation between biochemical and morphological changes to prove "Ca2+-mediated metabolic death"8~13) representing a mechanism of NC death caused by C5b-9 attack. The L1210 cells, mouse leukemic cell line carrying small complement channel(TAC5b-91) were used in the experiments. The amounts of intracellular adenine nucleotides to extracellular Ca2+, ouabain, KC1 and dextran were analyzed by bioluminescence method using luminometer. Cell viability was checked by 0.4% trypan blue dye and LDH release. Morphological observation of TAC5b-91 was done by immunocytochemical staining and electron microscope. The results were as follows: 1) The release of ATP, ADP and AMP followed by cell death was rapid and progressive along the incubation time at 37 degrees C and it was accelerated in 1.5 mM of [Ca2+]0. 2) There was no evidence of ATP repairment in the TAC5b-91. 3) Extracellular KC1(150 mM), dextran(0.66 mM) and ATP supplement(0.2 microM) could not effectively inhibit ATP depletion and cell death. Ouabain(27 and 100 microM) enhanced cell death and could not completely prevent ATP loss. 4) Most of the mitochondria showed swelling, loss of cristae and Ca2+ deposit in matrix in the electron microscopic observation. Rapid, sustained and irreversible depletion of adenine nucleotides was due to Ca2+ deposit with destruction of mitochondria and also the leakage through transmembrane channels. Moreover this energy depletion was accelerated by high extracellular Ca2+ concentration. These results indicate that Ca2+-mediated, energy exhaustion is one of the mechanisms of the metabolic cell death by C5b-9 attack of NC.
