Background & PURPOSE:Since the 1970's the rate of breast-feeding has decreased significantly. The Korean National Institute of Health reported that the rate of breastfeeding was 68.9% in 1982 and 14.1% in 1997. There are many influencing factors including: the lack of education and information on breast feeding, lack of faith in breast feeding, increment of the rate of working, lack of encouragement by supporters in difficult situations, and nurses' low level of knowledge about breast feeding. Such a lack of knowledge and support of breast-feeding at home by family members create another dilemma to the problem of breast-feeding. If problems arise and family members are unable to provide assistance due to the deficiency of knowledge, mothers show a tendency to abandon breast-feeding. The purpose of this research is to find out the rate of breast-feeding practice by time sequence of 1 week, 6 weeks and 12 weeks after birth and influencing factors on breast-feeding practice centered on the postpartal women who were 3discharged from one hospital, which is located in Seoul and provides simple breast-feeding education and continuous postnatal telephone consultation. Methodology: The subjects of this research were 54 women who gave birth in a hospital located in Seoul from 1 March 2000 to 31 April 2000. After birth the subjects were educated individually about breast-feeding and telephone consultations were conducted. On the 1st week, 6th week, and 12th week, the subjects were surveyed about their breast-feeding practice rates and methods by telephone. Results: 1) Complete breast-feeding rate: Within one week after birth, the subjects showed 64.2% complete breast-feeding rate. Within 6 weeks, 39.6%, and 12 weeks, 34.1%. 2)Partial breast-feeding rate: Within one week after birth, the subjects showed 32.1% partial breast-feeding rate. Within 6 weeks, 39.6%, and 12 weeks 15.1%. 3)Complete bottle-feeding rate Within one week after birth, the subjects showed 1.9% complete bottle-feeding rate. Within 6 weeks of giving birth 15.1%, and 12 weeks 17.0%. These results show that individual education about breast-feeding and continuous postnatal telephone consultation influenced on the practice of breast-feeding. On considering the reality of the hospital situation in which nurses could not operate education program due to the work-load, it is necessary to find out selectively those mothers who are unable to breast feed and provide education individually and continuous support by telephone follow up. Futhermore, the active role of lactation nurse specialist and their efficient management of breast-feeding for the successful practice is required.

We investigate the serial change of the bone density of the lengthening sites in distraction osteogenesis in long bone lengthening of the lower extremity by measuring the pixel value of the PACS(Picture Archiving Communication System). The purpose of this study was to find the clinical implication of the pixel value in PACS in the distraction osteogenesis. The number of the distraction sites were 22 in tibia and 16 in femur. The average distraction length was 4.5cm ranged between 2.1cm and 7.0cm in femur, 4.1cm ranged hetween 1.9cm and 6.8cm in tibia. When the image were sent to the PACS workstations, they were directly interfaced to the workstation without any processing. The absolute and the relati ve pixel values of cortical bones of the original and the lengthening sites repr sented in workstation of PACS were obtained by average value measuring 3 times by 3 different persons. The average absoiute pixel value of the original cortical bone near distraction site was not significantly changed, maintaining 575+/-6 in femur, and 570+/-7 in tibia. The absolute pixel vaIues in AP and lateral view were not significantly changed until 6 week/cm, but rapidly increased after 7 week/cm hoth in the tibia and the femur. The relative pixel value of the lengthening sites were more than 95% in three of the four cortices at the time of the removal of the external fixators. in conclusion, the pixel value of the PACS can be a rapid, simple and easy method for detection of the change of the bone density in distraction osteogenesis.

Primary non-Hodgkin's lymphoma of the brain is a rare malignancy and there are known to occur almost exclusively in brain parenchyme. Recent immunological advances and immunohistochemical techniques have provided new insights into the pathogenesis and diagnosis of the malignant lymphoma even in the small biopsied tissue and the majority of these CNS tumors is thought to be derived from B lymphocytes. A 22-year old man was admitted due to headack, dizziness and walking difficulty for 2 months. On the initial CT scan, there were two enhancing lesion in the suprasellar area and pineal gland which were completely disappeared with steroid therapy and three new lesions appeared on the follow-up CT and MRI studies in corpus callosum, third ventricle and left cerebral peduncle. The serial cytologic smears of cerebrospinal fluid and a stereotaxic biopsy tissue from the corpus callosum mass showed diffusely homogenous infiltration of neoplastic large noncleaved lymphocytes with focal perivascular arrangement. On the immunocytochemical stains, the reaction was negative for GFAP, positive for LCA and MB2, and negative for MT1. After radiation therapy, the masses completely disappeared on the follow-up CT scan and the patient was discharged free of all the clinical symptoms.

We have experienced acute hepatitis after general anesthesia. We guess that acute hepatitis is caused by enflurane anesthesia. We will report this case with references. A 34 year old pregnant woman suffered from preeclamsia. She admitted for emergence repeat cesarean-section due to labor pain. In this operation general anesthesia was performanced with enflurane. The preoperative liver enzyme were normal and other tests were within normal range. She developed high fever, marked elevation of serum glutamic oxaloacetic transaminase(SGOT)/serum glutamic pyrubic transaminase(SGPT)/ alkaline phosphatase(ALP)/total bilirunbin(T-B) on the 2nd postoperative day. She recovered gradually and discharged after 13 day's hospitalization. A possible cause of the acute hepatitis in this case were considered to be the enflurane.

Melanotrichoblastoma is a variant of pigmented trichoblastoma that shows highly pigmented epithelial lobules and differentiation toward the hair bulb. Histologically, the tumor presents features of trichoblastoma, and the histological findings are remarkable by virtue of the heavy melanin deposits found within and around the tumor cell nests. For the immunohistochemistry, abundant dendritic melanocytes (with the expressions of S100 protein, tyrosinase and most importantly, gp100/HMB45) are found within the tumor masses. We report here on a rare case of melanotrichoblastoma in a 57 year-old female patient.

Enterobiasis is a common disease among school-aged children, with worldwide distribution and high prevalence in countries with a temperate climate. Enterobius vermicularis usually inhabits the intestinal lumen, and the majority of clinical presentations are perianal pruritus. Extraintestinal infection is uncommon, mostly involving the female genital tract. It has been reported to occur in the peritoneal cavity, ovary, fallopian tube, endometrium, lung, liver, urinary tract and perianal tissue. In Korea, there has been only 1 case of enterobiasis presenting as perianal abscess in the Korean pathologic literature. So we present here an unusual case of perianal granuloma by Enterobius vermicularis in a 62-year-old woman.

OBJECTIVE: To identify the thickness of gastrocnemius muscles (GCM) in normal children and children with spastic cerebral palsy using ultrasonography and to determine the influencing factors in order to increase the accuracy of intramuscular injection of botulinum toxin A. METHOD: Fifty-six children with spastic cerebral palsy (Group A) with no fixed contractures or operation history were involved in this study and they were compared with normal children (Group B). Children lay prone and one examiner measured the thickness of medial and lateral GCM using ultrasonography. Relationship between GCM thickness and clinical variables (age, height, weight, body mass index (BMI), calf circumference, Gross Motor Function Classification System (GMFCS) level, spasticity, number of botulinum toxin injections) were determined with Pearson's correlation. RESULTS: The thickness of medial and lateral GCM were 78.06+/-14.66 mm, 66.90+/-12.23 mm respectively, in Group A, and 103.44+/-12.04 mm, 79.95+/-9.76 mm respectively, in Group B. Medial GCM were thicker than lateral GCM in both groups. The age, height, weight, BMI, calf circumference and the thickness of GCM were higher in Group B. In group A, weight, BMI, calf circumference showed positive correlations with the thickness of medial GCM and GMFCS showed negative correlation with the thickness of medial GCM. CONCLUSION: To increase the accuracy of intramuscular injection of botulinum toxin A, we should keep in mind that the thickness of GCM may be influenced by several factors. Further controlled study including larger group is needed.

Epithelioid hemangioendothelioma(EH) is a rare vascular tumor of low-grade malignancy. It was previously described as intravascular bronchioloalveolar tumor (IVBAT). But electron microscopic study and immunohistochemical staining results have proved endothelial origin. Patients are usually asymptomatic and the tumors are found incidentally on routine chest X-rays. Most patients show a slowly progressive clinical course, even though some patients occasionally die as results of respiratory failure or extrathoracic complications. Confirmative diagnosis is made through thoracoscopic or open-lung biopsy. There is still no effective therapeutic modality for pulmonary EH. We have experienced a 55-year-old woman whose simple chest x-ray film revealed bilateral multiple small nodules. The nodules were histopathologically and immunohistochemically diagnosed as primary epithelioid hemangioendothelioma of the lung. The possibility of metastatic disease was excluded thorough clinical, laboratory and radiological studies. Comparison of radiographic chest film taken 3 years ago showed no significant progression of the pulmonary nodular lesions. Conservative management was instituted and careful 4 months follow-up showed no significant changes.

BACKGROUND AND OBJECTIVES: Endolymphatic hydrops are known as major causes of Meniere's disease. MRI (Magnetic resonance imaging) with contrast tried recently makes it possible to visualize perilymphatic and endolymphatic space without invasive procedures. There are no tryouts in the interior of our country. We attempted MRI after injection of gadolinium-diethylen-triamine pentaacetic acid (Gd-DTPA) in normal adults and patients with Meniere's disease to make sure 3D-FLAIR (fluid-attenuated inversion recovery) MRI parameters and to visualize endolymphatic spaces. MATERIALS AND METHODS: Five normal adults and Five patients with Meniere's disease were included in this study. Twenty-four hours after Gd-DTPA intratympanic injection, we performed 3D-FLAIR and 3D-IR imaging at 3T. MRI region of interest signal intensity was used to determine the diffusion of Gd-DTPA into the perilymphatic fluid spaces over time. RESULTS: Five of five in normal group, using 3D-IR MRI after Gd injection, had enhanced imagings (perilymphatic spaces) of inner ears. Five of five in patients group, using 3D-IR after Gd injection, had enhanced perilymphatic spaces and non-enhanced endolymphatic hydrops. CONCLUSIONS: Delayed contrast imaging of the inner ear with 3D-IR MRI after Gd-DTPA intratympanic injection revealed in vivo visualization of endolymphatic hydrops.

Histopathology of pulmonary lymphangioleiomyomatosis(LAM) is studied using four new cases and six previously reported cases, which include two cases without definite evidence of LAM. The important diagnostic features of this lesion were nodular proliferation of immature smooth muscle and cleft or cyst formation within the nodules of smooth muscle cells. The nuclei of the smooth muscle cells were bigger than those of blood vessels or fibrotic lung, and the direction of nuclei was irregular. The lung parenchyma showed little inflammatory change but there were multiple air cysts with smooth muscle nodules at their margin. There were two cases with exuberant proliferation of smooth muscle nodules and two cases with papilliferous projections of the cells into lymphatic lumen. Whereas, three cases had only a few small slender nodules of smooth muscle cells at the margin of air cyst. The lymphatic lumen with smooth muscle nodules is dilated in four cases but other four cases show collapsed lumen. Pulmonary hemorrhage and hemosiderosis were prominent in three cases. There were variety of histology in terms of the cellularity of smooth muscle nodules, the size of the lymphatic lumen and the degree of pulmonary destruction, which may have significance on the clinical presentation and prognostication.
