Tracheoesophageal fistula (TEF) occurs in approximately 1 in 3,000 to 5,000 live births. TEF arises from failure of normal division of proximal foregut into separate respiratory and digestive tracts at 4 weeks' gestation. TEF and esophageal atresia are interrelated anomalies, and TEF usually occurs with esophageal atresia. These are usually diagnosed shortly after birth. However, the diagnosis is often delayed in TEF without esophageal atresia, because babies with this anomaly are usually normal in size and seldom have other anomalies. Therefore, sometimes TEF without esophageal atresia is found during operation for an unrelated condition when positive pressure ventilation causes massive inflation of the gastrointestinal tract. We report a case of TEF in adult patient found during general anesthesia for emergency exploratory laparotomy.

A clinical observation was made on 5 cases of primary ureteral tumors admitted to the Department of Urology, Presbyterian Medical Center during the period from August, 1970 through March, 1978. Clinical and radiographic findings are summarized below: 1. Among 5 cases of primary ureteral tumors, 4 cases in male, 1 case in female. 2. The range in age was from 58 to 75 years, average 66 years. 3. Duration of symptoms varied from 1 day to 1 year, common symptoms are hematuria and flank pain (1 case). 4. The side of lesion: left 3 cases , right 2 cases. 5. All tumors are located in the lower third of ureter. 6. The characteristic urographic and cystoscopic findings are as follows ; Non-visualizing kidney disclosed by intravenous pyelogram in 3 cases, hydroureteronephrosis in 2 cases. filling defect of ureter in 2 cases. The appearance of tumor in the orifice on cystoscopy in 2 cases. 7. Nephroureterectomy with excision of a cuff of the bladder was performed in all cases.

It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.

PURPOSE: We reviewed our data compiled prospectively for evaluation of post-operative complications and recurrence of laparoscopic inguinal hernia repair. METHODS: Among the 1000 patients (age, > or =20 years old) who were undergone laparoscopic inguinal hernia surgery from January 2007 to July 2011, the age, sex, location, hernia type, operation time, postoperative morbidity, and conversion of 992 patients were analyzed. RESULTS: Among 992 patients, 919 (92.6%) were male and the mean age was 54.2 years (range, 20~90). Operation times (m inutes) for unilateral and bilateral hernia were 40.0 and 53.4, respectively. Mean operation time (minutes) showed a decrease over time, as that for the first half of all cases was 43.5 and that for the second half was 39.7 (p<0.001). Seven cases of conversion (post-radical prostatectomy hernia=7) were recorded to TAPP (n=3) or IPOM (n=4) from TEP. Eleven cases of postoperative catheterization (1.1%), five cases of port site seroma (0.5%), one case of mesh removal due to infection, 24 cases of seroma/hematoma (2.4%), 26 cases of neuralgia (2.6%), and four cases of bleeding with a drop in hemoglobin of more than 3 mg% (0.4%) were also recorded. There were three cases of recurrence (0.35%) at the median follow-up of 46 months (range, 20 to 70 months). CONCLUSION: Laparoscopic inguinal hernia repair can be performed safely, with low rates of complication and recurrence. This technique achieves good results combined with the benefits of minimally invasive surgery. We should be cautious in order to avoid postoperative bleeding, especially in cases of TEP.

A case of multiple hamartomas of the unilateral chest wall in a four month old infant is presented. There have been a few reports on the CT findings of the chest wall hamartoma in infancy. We describe bone changes of the ribs and mineralization of this rare tumor on the CT scan, and the locations of two separate masses.

PURPOSE: The peripapillary retinal nerve fiber layer thickness (RNFL) was measured in normal children using optical coherence tomography (OCT), and the effect of various factors on the RNFL thickness was examined. METHODS: From April 2006 to January 2007, the RNFL thickness of 74 normal children (148 eyes) between the ages of 4 and 17 years old was measured by OCT, and the effect of factors such as age, gender, refractive error, C/D ratios, cooperation, and laterality on the peripapillary RNFL thickness was analyzed. RESULTS: The mean age of the patients was 10.2 years (4~17 years), and the mean peripapillary RNFL thickness was 106.3+/-12.8 micrometer. As to the thickness of the different peripapillary locations, the superior side was thickest (135.3+/-20.6 micrometer), followed in order by the inferior side (130.9+/-23.0 micrometer), the temporal side (86.3+/-18.9 micrometer), and the nasal side (71.9+/-20.8 micrometer). The refractive error was correlated positively with RNFL thickness (r=0.277, p=0.001), and age correlated negatively with RNFL thickness (r=-0.194, p=0.018). CONCLUSIONS: RNFL thickness in normal children increases as the refractive error becomes hyperopic and decreases with age. The data about RNFL thickness of normal children obtained in this study may provide useful information for an early diagnosis of pediatric neuroophthalmologic disease and for monitoring its progression.
