Oral mucositis continues to be a major complaint of patients who have chemotherapy for the acute leukemia. An innovative and inexpensive remedy which produces favorable results for those afficted is not yet introduced. So we tried to develop two oral care protocols for reducing the level of oral mucositis during cytotoxic therapy through literature review and our clinical experience. The one is sodium bicarbonate-normal saline gargling, and the other consists of chlorhexidine gargling. This quasi-experimental study was performed to compare the efficacy of these two different oral care protocols. Twenty subjects were assigned to one of the two specific diagnosis of leukemia, aim of the chemotherapy. The Oral Assessment Guide(OAG), the Beck's perception of oral comfort, WHO Grading system fot mucositis and the discomfort of oral gargling solution were used to assess oral status and subject's oral discomfort during chemotherapy. Each subjects were observed daily from the start of the chemotherapy until Absolute Neutrophil Count(ANC) reached 1,000. It continued about 2-4 weeks. The data analyzed by Mann-Whittney U test and ANCOVA. The result was follows as: The patient who used sodium bicarbonate-normal saline gargling showed significantly higher mean score of the discomfort of oral gargling solution than chlorhexidine gargling. The other scores were not significantly different between two groups. However the subjects using the sodium bicarbonate-normal saline gargling showed a lower level of oral mucositis. We concluded that oral using sodium bicarbonate-normal saline gargling was between to reduce the level of oral mucositis during chemotherapy and nursing assessments of the oral cavity seemed to promote patient's compliance with the oral care regimen.

To investigate the immunohistochemical expression of mutated p53 protein and bcl-2 protein in the cutaneous melanocytic lesion, 15 cases of compound nevus, 10 cases of congenital melanocytic nevus, 15 cases of primary malignant melanoma(4 cases less than 1.5 mm thick and 11 cases more than 1.5 mm thick), and 10 cases of metastatic malignant melanoma(7 cases in lymph node and 3 cases in soft tissue) were examined. All cases of compound nevi and of congenital melanocytic nevi showed no immunoreactivity for p53 protein. p53 protein overexpression was observed in 75%(3/4) wth primary malignant melanoma less than 1.5 mm thick, 81%(9/11) with primary malignant melanoma more than 1.5 mm thick, and 100%(10/10) with metastatic malignant melanoma. The difference in p53 protein overexpression was statistically significant between benign nevi and malignant melanoma(p<0.01). Bcl-2 protein expression was observed in 73%(11/15) with compound nevus, 70%(7/10) with congenital melanocytic nevus, 75% (3/4) in primary malignant melanoma less than 1.5 mm thick, 54%(6/11) with primary malignant melanoma more than 1.5 mm thick, and 40%(4/10) with metastatic malignant melanoma. These findings suggested that mutation of p53 gene may be an important mechanism in the development of malignant melanoma. Although bcl-2 protein was expressed in cutaneous melanocytic lesion, no correlation was found between p53 protein and bcl-2 protein expression in malignant melanoma.

OBJECTIVE: The conventional methods to determine fetal genetic status, such as amniocentesis or chorionic villi sampling(CVS) have small procedure-related risk of abortion. Recently, several researchers reported that fetal genetic status, such as sex, can be confirmed by fetal nucleated erythrocytes in maternal blood and this method might reduce such risk. Therefore, in this study, we attempted to determine the basic fetal genetic status, sex, with fetal nucleated erythrocytes. METHODS: In twelve pregnant women who undertook amniocentesis or CVS, 20 ml of venous blood was drawn immediately before the procedure and the nucleated erythrocytes were recovered by magnetic activated cell sorting(MACS). After MACS, DNA was extracted from 200 microliter of sample and single nucleated erythrocyte was obtained by additional procedure, immunostaining, and microdissection. After recovery of nucleated erythrocytes by microdissection, nested polymerase chain reaction(PCR) and fluorescent PCR of amelogenin gene were performed to identify the fetal gender. RESULTS: The DNA of enriched erythrocytes after MACS could identify the fetal gender in the 58.3% of the samples by nested PCR. After the recovery of single nucleated erythrocyte by MACS, immunostaining and microdissection, the minute DNA in a single cell could be amplified by primer extension preamplification(PEP), nested PCR, and fluorescent PCR. Fetal genders were correctly identified in 8 out of 12 (66.7 %). CONCLUSION: Through this study, we could conclude that fetal nucleated erythrocytes in maternal blood might be sufficient sample to determine fetal sex. And single cell isolation by microdissection could get the better results than nested PCR after MACS only. However, in spite of the pregnancy of male fetus, female specific bands were obtained after nested PCR of amelogenin in several cells, which might suggest that part of nucleated erythrocytes in maternal blood might be maternal origin. Therefore, to determine fetal genetic condition by nucleated erythrocytes in maternal blood, further improvements of methods to identify the nucleated erythrocytes of fetal origin are needed.

Shaken baby syndrome refers to the group of nonaccidental injuries occuring in infants and children as a consequence of violent shaking. The characteristic injuries include subdural and subarachnoid hemorrhages, retinal hemorrhages, traction-typed metaphyseal fracture of long bone and fractures of the ribs. General physical findings may include bruising and burns, but sometimes no extracranial injuries are detected. Affected children are nearly always under 2 years of age or younger. Common symptoms include lethargy, irritability, seizures, increased or decreased muscle tone, poor feeding, impaired consciousness, vomiting and apnea. We experienced a case of shaken baby syndrome in a 3-month-old girl. Although the history of trauma(shaking) is little known, our findings of clinical and radiographic features corresponded to shaken baby syndrome. (J Korean Pediatr Soc 2000;43:851-855)
