Tracheal gaenesis is an extremely rare congenital anomaly and is characterized by totally or partially undeveloped trachea. In many instances, the lesion has been associated with malformations in other organ systems. This anomaly is classified into 3 types based on developmental period of the respiratory tract. We report a case of tracheal agenesis with tracheoesophageal fistula in a 2-hour-old male. Postmortem examination revealed that the upper and mid portion of the trachea was absent but 1 cm segment of the trachea above the carina was present. The proximal end to this trachea opened to the esophagus by a fistula, 1 cm in diameter. The well-formed larynx ended blindly in a fibrous sac at which thyroids and cartilage islands are noted. Associated anomalies were bilobed right lung and single umbilical artery.

By Enzinger and Weiss classification, 664 cases of soft tissue tumors, which were confirmed histologically at the department of pathology of Hangang Sacred Heart Hospital from Janusry 1979 to December 1988, were analyzed statistically. The results were as follows : 1. Of the 664 cases, 261 cases (39.3%) were consulted at the Department of General Surgery, 124 cases (18.7%) were consulted at the Department of Orthopedic Surgery, 115 cases (17.3%)were consulted at the Department of Dermatology. 2, Of the 664 cases, 631 cases (95%) were benign and 33 cases (5%) were malignant. 3. The most common benign tumor was lipoma, which was followed by hemangioma and lymphangioma. Among malignant tumors liposarcoma was the most common one, followed by malignant fibrous histiocytoma. 4. The distribution of age of benign tumor was relatively even from childhood to old age but that of malignant tumor showed highest prevalence in 7th decade. 5. The distribution of sex of benign tumor showed male to female ratio of 1: 1.1 but that of malignant tumor showed male to female ratio of 1.5: l. 6. The predilection sites of benign tumors were head, neck and trunk, but those of malignant tumors were lower extremities and trunk. 7. Kinds of soft tissue tumors consulted at the Department of Dermatology were hemangioma, neurofibroma, lipoma, dermatofibroma, ymphangioma, leiomyoma, juvenile xanthogranuloma, xanthoma, keloid and neurilemmoma.

A case of neonatal hemochromatosis in a 3-hour-old male is described. He presented with hypotonia, mild jaundice, and respiratory difficulty immediately after birth. He had no evidence of congenital infection, immune-related hemolysis or exogenous iron uptake. Postmortem examination revealed abnormal facial features. The organs were of normal weight for his age except a small liver and lungs, and a large spleen. The most prominent changes were in the liver and pancreas. The liver was coarsely nodular and fibrotic. The lobular architecture was totally distorted by innumerable multinucleated giant cells, loss or collapse of the hepatocytes, and diffuse fibrosis. A large amount of hemosiderin was seen in the liver, pancreatic acini and thyroid follicular cells. Scanty amount of hemosiderin was also found in the myocardial fibers and renal tubular cells. The pancreas showed hyperplasia and hypertrophy of the islets. The spleen showed severe congestion and a moderate extramedullary hemopoiesis but no deposits of hemosiderin. This patient had three siblings died in neonatal period, one of which had clinical features of neonatal hemochromatosis.

PURPOSE: Brain metastasis from colorectal cancer is a rare clinical condition. We have experienced five cases of brain metastases in a relatively short period of time during extensive chemotherapy for advanced colorectal cancer. To examine whether this phenomenon is a simple coincidence or there is a correlation with prolongation of life span in patients with stage IV colorectal cancer, we analysed five patients with brain metastases. METHODS: The case histories of 47 patients with unresectable systemic metastases who had undergone sequential chemotherapy (FOLFOX and FOLFIRI) in Ajou University Hospital from August 2002 to December 2004 were reviewed and analyzed for clinical characteristics. The sites of unresectable metastases were the liver (n=28), the lung (n=28), and the paraaortic nodes (N=6). Diagnostic criteria of unresectable metastasis were multiple or bilobar lesions in hepatic metastasis and multilobar involvement in pulmonary metastasis. RESULTS: There was no complete remission. Partial remission was noted in 31.9% of the patients and stable disease in 8.5%. Sequential chemotherapy showed no effect in 59.6% of the patients. Brain metastases occurred in five patients (10.6%). Accompanying metastases were found in the lung (n=4), the liver (n=3), the paralortic lymph nodes (n=2), and bone (n=1). Four patient (21.0%) were noted in the response group. The mean interval from primary cancer surgery to the diagnosis of brain metastasis was 27.5 (20~44) months. From the start of chemotherapy, brain metastasis was diagnosed at an average of 10.5 (8~16) months. Metastasectomies were performed in three patients, and stereotaxic radiosurgery was performed in two patients. One patient died with the disease, and four patients have been alive with the disease for more than six months. CONCLUSIONS: It is still unclear whether the increasing incidence of brain metastasis is related with prolongation of life expectancy in patients with stage IV colorectal cancer. However, about half of the stage IV colorectal cancer patients were found to obtain meaningful survival benefits by sequential chemotherapy, and 20% of chemo- responders showed brain metastases. Therefore, we conclude that the increasing incidence of brain metastasis seems to correlate with prolongation of life expectancy in stage IV colorectal cancer.

BACKGROUND: The frequency of bloodstream infection by Candida species has dramatically increased in recent years. Many of bloodstream infections caused by candida arise from an endogenous source of mucosal colonization, as well as exogenously from the hospital environment. We analyzed the prevalence of Candida species isolated from blood cultures, and compared it to those of all other clinical specimens, and those of the hospital environment. METHODS: Identification of Candida species was performed on isolates from blood cultures (159 strains), from cultures of clinical specimens other than bloods (1,609 strains) and from cultures of the hospital environment (30 strains). All candida isolates were recovered between January 1997 and June 1998 at Chonnam University Hospital. Candida surveillance cultures of the hands and nares of 77 medical personnel were performed using CHROMagar Candida. RESULTS: Among the Candida species isolated from the blood cultures, C. parapsilosis was the most frequently isolated (35.2%), followed by C. albicans (29.6%), C. glabrata (9.4%), and C. tropicalis (8.8%). The Candida species frequently isolated from clinical specimens other than bloods were C. albicans (52.6%), C. glabrata (19.1%), and C. tropicalis (15.3%). While C. parapsilosis was not frequently isolated from clinical specimens other than blood (3.4%), it was the most frequent Candida species isolated from the hands of medical personnel. Sixteen (20.8%) out of 77 medical personnel were found to harbor C. parapsilosis on their hands. CONCLUSION: These results suggest that it is possible that most of the Candida species causing bloodstream infections are from mucosal colonized strains, but that C. parapsilosis may be acquired from exogenous sources.

PURPOSE: The exact role of postoperative radiotherapy following curative surgery of rectal carcinoma has been debated. In this retrospective study, we examined the effect of radiotherapy on the survival and recurrence rate of rectal cancer patients who underwent total mesorectal excision (TME). METHODS: Since June of 1994, we have recommended postoperative chemoradiation (6 cycles of 5-FU with folinic acid plus 5040 cGy external irradiation) for stage II and III rectal cancer patients. Among 134 stage II and III rectal cancer patients who underwent TME, 100 patients received postoperative chemoradiation (group A) and 34 patients decided not to receive radiation therapy (group B). For these two groups, survival and recurrence rates were compared. Follow-up times were 6 to 60 months (mean 24.7). There was no difference between two groups with regard to sex, stage of the disease, mean tumor location from dentate line, status of lateral margins, type of operation and mean follow-up duration. However, mean age was higher in group B (65.6 vs 53.9, P<0.05). RESULTS: The overall recurrence rate showed no difference between two groups (28.0% in group A vs 21.0% in group B, P>0.05). Local recurrence rate was also similar (11.0% vs 3.0%). There was no significant difference in duration between surgery and initial recurrence (14.0 months vs 11.0 months, P=0.18). The 5-year-disease-free survival rate was 57.0% in group A and 63.0% in group B (P=0.33). CONCLUSION: In this study, we found no beneficial effect of postoperative radiation therapy following TME for the rectal cancer.
