Patients with AIDS frequently present with pulmonary complications which are associated with a high mortality rate and infections are the most important cause of lung infiltrates. In addition to pneumonia caused by Pneumocystis carinii, which was noted in early reports of the syndrome, a variety of other severe pulmonary disorders may occur. Frequently more than one organism is found in a single patient and among these, combined infections of Pneumocystis carinii and cytomegalovirus are the most common. We experienced a case of combined Pneumosytis carinii and Mycobacterium tuberculosis infection as a pulmonary manifestation of AIDS in a 38-year-old man. In bronchoalveolar larvage, bronchial washing and brushing, and sputum smear specimens, Pneumocystis carinii organisms were recognized, especially in Gomori's methenamine silver stains. Transbronchial lung biopsy specimen revealed intra-alveolar frothy exudates composed of collections of Pneumocystis carinii organisms as well as several granulomas with central caseous necroses.

PURPOSE: This study was performed to evaluate the dietary nutrient intake status and hair mineral content of Korean young children. METHODS: Fifty-five children who visited Seoul National University Bundang Hospital were divided into three groups by age: infants, toddlers, and preschoolers. The 24-hour recall method was used to collect the food intake data of the subjects. Hair mineral analysis was conducted using a Mass Spectrometer. Serum iron, ferritin, and calcium were also measured. RESULTS: The mean energy intakes of the subjects were 730.3 kcal, 994.3 kcal, and 1,482.9 kcal for each age group. The mean percentage of energy intake compared to recommendation was 101.4% and was not different by age group. Toddlers of 37.8% and preschoolers of 54.5% consumed less than the Estimated Average Requirement (EAR) of calcium. Infants of 28.6%, toddlers of 10.8% and preschoolers of 9.1% consumed less than the EAR of iron. In the case of zinc, copper, and selenium, only 0% to 5% of toddlers and none of the preschoolers consumed less than the EAR of those minerals. The hair calcium, iron and copper concentrations were lower in toddlers and preschoolers than those in infants. Serum calcium levels of preschoolers were significantly lower than those of infants, whereas serum iron and ferritin levels were not. CONCLUSION: Hair calcium, iron, and copper concentrations were significantly lower in toddlers and preschoolers than in infants. Insufficient dietary intake of calcium and iron seems to be related with decreased hair mineral contents in young children.

OBJECTIVE: We investigated the expression of uPA and uPAR in eutopic endometrium of advanced stage endometriosis and control patients. METHODS: The 33 endometriosis patients and 32 controls were enrolled. Endometrial samples were obtained from 65 premenopausal women aged 29~44 years, undergoing laparoscopic surgery or hysterectomy for non-malignant lesions. Sufficient samples were collected from 33 patients with endometriosis stage III and IV and 32 controls without endometriosis confirmed by laparoscopic surgery. The mRNA expression of uPA and uPAR from eutopic endometrium were analyzed by RT-QC PCR. RESULTS: The mRNAs of uPA and uPAR were expressed in eutopic endometrium from endometriosis and normal controls throughout the menstrual cycle. Uterine endometrium from women with endometriosis expresses significantly (p<0.05) higher levels of u-PA mRNA than endometrium from normal women without endometriosis in the proliferative phase. There were no significant differences in expression of uPAR in eutopic endometrium between controls and endometriosis patients. CONCLUSION: These results suggest that eutopic endometrium from endometriosis patients may be more invasive and prone to peritoneal implantation because of greater u-PA mRNA expression than endometrium from women without endometriosis. Thus, increased proteolytic activity may be one etiology for the invasive properties of the endometrium resulting in the development of endometriosis.

Alzheimer's disease (AD) is an age-related disorder. Both the prevalence and the incidence of AD double approximately every 5 years after the age of 60. This is a particularly serious problem considering that the Korean elderly population is rapidly growing. We present three illustrative cases of AD in mild, moderate, and advanced stages, respectively. Their initial symptoms were memory impairment which was followed by language disturbance and visuospatial dysfunction. Abnormal behaviors such as delusion and aggression occurred in moderate and severe cases. The presence and severity of dementia in these cases were established by history taking, neurological examination, standardized mental status assessment, and neuropsychological test. Laboratory investigations showed no abnormalities that could account for the cognitive deficits. Brain CT or MRI findings of the patients wee not remarkable except for a diffuse atrophy demonstrated by increased ventricular volume, narrowed gyri, and widened sulci, As an addendum, risk factors, clinical symptoms, clinical diagnosis, and natural history of AD were reviewed.

PURPOSE: We report clinical charateristics of percutaneous central venous catheteriza- tion(PCVC) that is performed commonly as a vascular access procedure in the neonatal intensive care unit(NICU) including comparision between the success rate and com- plication rate of groups performed by a doctor and by nurses who were accustomed to the IV procedure. METHODS: We evaluated a total of 158 PCVC cases performed in the NICU of Soonchunhyang Chunan hospital over 2 years 5 rnonths from May, 1995 to September, 1997. The 24 cases of PCVC were performed by doctors and 134 cases of this proce- dures were performed by well trained nurses. We have compared success rates, clinical characteristics, insertion sites, indwelling time, causes of removal of the catheters, and associated complication of both doctor performed group (D) and nurse performed group (N) retrospectively. RESULTS: The mean gestational age, birth weight, weight at the time of insertion were significantly lower in the doctor performed group than in the nurse group(P<0.001). There were significant differences in postnatal age and mean duration per catheter in both groups. The overall success rate of insertions was 89.9%(142/158), the success rate of doctor performed group was 54.2%(13/24) and nurse group was 96.3%(129/134) and there was significant difference(P<0.001). In the doctor performed group, 100% were axillary however in the nurse group 43.4% were axillary, 38.8% were antecubital, 9.4% were temporal, and 5.4% were hand. The most common cause of the removal of the catheter was elective in both groups but there was also substantial spontaneous removal by the patients and mechanical complication. Cultures of catheter tips were done after removal in 110 cases, among then were positive in 36 cases(33.6%), the most common causes were Staphylococcus aureus and Candida albicans. CONCLUSION: In this report, the authors emphasize that percutanous central venous catheterization performed by well trained nurses has a higher success rates than the doctor performed group and can be considered safe. We would also like to emphasize that more attention should be paid to the maintanace of PCVC.
