A three year old girl with a left renal teratoid Wilms tumor is reported. The tumor was located both inside and outside the kidney parenchyme, to form a well encapsulated mass containing two lobulated solid and cystic masses. The tumor consists predominantly of otherwise typical Wilms tumor irregularly mixed with teratoid tissue elements such as intestinal tract, mucous glands with argentaffin cells, goblet cells and transitional epithelium. These heterologous elements were regarded as diverse epithelial differentiation of totipotent cells in certain nephrogenetic period, and this tumor was considered to be hest called "teratoid Wilms tumor".

An autopsy case of male pseudohermaphrodite associated with Bochdalek diaphragmatic hernia is reported. This newborn infant showed a large clitoris and hypospadic urethra which was the only opening in the perineum except for the anus. There were urethrovaginal fistula and uterus didelphys. The adrenals were slightly larger than normal, but microscopically did not show any features of cortical hyperplasia. Well formed testes were found and were histologically unremarkable. In addition, Bochdalek type of diaphragmatic hernia was present, associated with severe left lung hypoplasia and massively herniated abdominal organs into the chest cavity, shifting the mediastinum considerably and eventually led to death in a few minutes after birth. The pathogenesis of genital anomaly and diaphragmatic hernia is briefly discussed and it is suggested that this type of genital abnormality might be due to defect of testicular M llerian inhibitor factor and can be categorized as incomplete male pseudohermaphroditism.

Pulmonary thromboembolism (PTE) is a serious postoperative complication. Prompt diagnosis of PTE is important but it is difficult because clinical manifestations of PTE are not obvious in most cases. A 59 year-old woman received cholecystectomy and choledocholithotomy under general anesthesia. At the 9th postoperative day, syncope, hypoxemia and hypotension were developed suddenly and the patient was transfered to intensive care unit. PTE was suspected with hemodynamic monitoring from pulmonary arterial catheter and echocardiography and diagnosed with lung perfusion scan and venogram of lower extremities. Proper cardiopulmonary support was done and the patient was recovered and discharged in improved condition. In conclusion, if a patient have syncopal attack with shock in postoperative period, PTE must be thought to be an one of possible causes of syncope and thoroughly investigated.

PURPOSE: This study was performed to investigate the prevalence of Staphylococcus aureus (S. aureus) nasal carriage in Korean children attending day care centers. METHODS: During September and October 2009, a survey for nasal carriage of S. aureus and methicillin-resistant S. aureus (MRSA) was conducted among children attending day care centers located in Seoul with questionnaire survey for evaluation of risk factors of acquisition of MRSA was obtained from their guardians. A culture of the anterior nares swabs using enrichment broth was executed for isolating S. aureus and oxacillin susceptibility was assessed by the disk diffusion method. RESULTS: Out of the 428 children enrolled whose mean age was 55 months old, 163 (38.1%) were colonized with S. aureus. Of the 163 isolates, 40 (24.5%) were MRSA. The nasal carriage rate of S. aureus showed an increasing trend with increase of age. Based on the answer to the questionnaire, 9.2% and 3.6% of children had a recent history of hospitalization and surgery, respectively, and approximately 40% of children had a history of prescription of antibiotics within 1 year prior to enrollment. Of the 428 subjects, 40 (9.3%) were MRSA nasal carriers. CONCLUSION: S. aureus and MRSA carriage rate of children attending day care center in Korea was 38.1% and 9.3%, respectively. Continued surveillance for nasal carriage rate of S. aureus and MRSA (especially community-associated MRSA) is mandatory.

The advent of computerized cranial tomography made a greater advance in the diagnosis of very wide variety of intracranial lesions. Authors analyzed 58 pathologically proven sellar and parasellar tumors examined at Kyung Hee Un-iversity Hospital from Oct. 1977 to Jun. 1981 and the results were as follows; 1. The distribution of the tumors is 28 pituitary adenomas, 18 craniopharyngiomas, 5 meningiomas, 4 germinomas, 2 astrocytomas, and 1 sphenoid mucocele. 2. In pituitary adenoma, the precontrast CT scan of tumors appeared as isodensity in 11 cases, mixed density in 8 cases, high density in 6 cases, and low density in 3 cases, and associated with destruction of sellar turcica in 15 cases, calcification in 3 cases, and hydrocephalus in 2 cases. The postcontrast CT scan study revealed 24 cases of contrast enhancement, including 17 cases of homogenous and 7 cases of ring or rim enhancement. 3. In craniopharyngioma, the precontrast CT scan of tumors appeared as low density in 12 cases, isodensity in 4 cases and high density in 2 cases and associated with calcification in 16 cases, hydrocephalus in 15 cases and destruction of sellar turcica in 2 cases. The postcontrast CT scan study revealed no enhancement in 10 cases and contrast enhancement in 8 cases including 6 of ring enhancement and 2 heterogenous enhancement.

PURPOSE: The aim of this study was to identify mutations associated with macrolide resistance in Mycoplasma pneumoniae (MP) and to establish a cultural method to determine antimicrobial susceptibility. METHODS: Nasopharyngeal aspirates (NPAs) were collected from 62 children diagnosed with MP pneumonia by a serologic method or polymerase chain reaction. The 23S rRNA and L4 ribosomal protein genes of MP were amplified and sequenced. To identify mutations in these 2 genes, their nucleotide sequences were compared to those of the reference strain M129. MP cultivation was carried out for 32 (28 frozen and 5 refrigerated) NPAs and M129 strain using Chanock's glucose broth and agar plate in a 5% CO2 incubator at 37degrees C and examined at 2-3 day intervals for 6 weeks. RESULTS: Among the 62 specimens, 17 had M144V mutations in ribosomal protein L4. The A2064G mutation was observed in 1 specimen; its 23S rRNA gene was successfully sequenced. Culture for MP was successful from the M129 strain and 2 of the 5 NPAs that were refrigerated for no longer than 3 days. However, MP did not grow from the 28 NPAs that were kept frozen at -80degrees C since 2003. CONCLUSION: We found the M144V mutation of L4 protein to be common and that of domain V of 23S rRNA gene was relatively rare among MP. Studies on the prevalence of macrolide-resistant MP and the relationship between the mutations of 23S rRNA gene and ribosomal protein L4 will aid in understanding the mechanism of macrolide resistance in MP.

OBJECTIVE: Vascular Endothelial Growth Factor (VEGF) is a potent stimulator of angiogenesis in solid tumors. Thrombospondin-1 (TSP-1) has inhibitory role in cancer cell proliferation and metastasis. To analyze the correlation with expression of VEGF and TSP-1 including microvessel density (MVD), the levels of VEGF/TSP-1 mRNA expression and microvessel count (MVC) were estimated in patients with invasive cervical carcinomas. METHODS: From 1996 to 1999, 37 carcinomas and 7 normal cervical tissues were collected, frozen and stored at -70 degrees C until used. The levels of VEGF and TSP-1 mRNAs were determined by quantitative RT-PCR. MVD was assessed by immunostaining for factor VIII-related antigen. The results are expressed as the largest number of microvessels present within a single x 40 field, and counted at x 100 field. RESULTS: Quantitative RT-PCR analysis demonstrated abnormally increased VEGF mRNA expression levels (>0.66) in 14 (37.8%) of 37 cervical carcinomas comparing to control groups (mean: 0.32+/-0.09) and abnormally low TSP-1 mRNA expression levels (<0.72) in 13 (35.1%) of 37 cervical carcinomas comparing to control groups (mean: 0.51+/-0.07). MVC was higher in tumors showing decreased expression of TSP-1 (but not statistically) (p<0.18) and overexpression of VEGF (p<0.05). When VEGF overexpression was accompanied with reduced TSP-1 expression, the microvessel density showed significantly increased pattern (p<0.05). CONCLUSION: Our study demonstrates that reduced expression of TSP-1 mRNAs and overexpression of VEGF mRNAs may be an important contributing factor in cervical carcinomas. Moreover, the inversed correlation of VEGF and TSP-1 mRNA expression can be an evidence of angiogenic role in cervical carcinomas.
