Typhlitis or neutropenic enterocolitis is a life-threatening, necrotizing process of the cecum whose incidence is increasing. Typhlitis presents as fever, abdominal pain, and diarrhea in neutropenic patients. As the incidence of typhlitis increases, emergency physicians must be aware of this rapidly progressive and potentially fatal disease. The definitive management of typhlitis is controversial. The most prudent course for the emergency physician is to initiate aggressive medical management early in the ED. We describe a 25-year-old man with severe neutropenia presented to the emergency department with fever, abdominal pain, diarrhea that began 2days earlier. Abdominal computerized tomography(CT) demonstrated diffuse concentric thickening of the cecal wall, intramural edema, inflammatory bowel changes but no free air and abscess formation. He was recovered by early diagnosis and aggressive medical therapy. We report a case of typhlitis with literature reviews.

Isolated infernal iliac artery aneurysms and rupture are relatively infrequent, often difficult to detect and therefore rarely considered in the differential diagnosis for abdominal pain. The consequences can be grave, The incidence of isolated iliac artery aneurysm is 1~2% of that of abdominal aortic aneurysm(AAA). The natural history is of gradual enlargement, with rupture the most common clinical presentation. The signs and symptoms of such an aneurysm are influenced by its concealed location within the bony pelvis. Awareness of these special characteristics improves the chances of early diagnosis and proper surgical treatment before possible rupture. Here is a case of ruptured aneurysm of left internal iliad artery. A 73-year-old man was presented to our emergency center with severe abdominal pain and voiding difficulty Abdominal Computed Tomography(Cf) and angiography showed ruptured aneurysm of left infernal iliad artery. Emergency operation was successfully performed for the ruptured internal iliad artery aneurysm.

Among the precancerous lesions, dysplasia of the uterine cervix and adenoma of the colon have been widely studied in terms of genetic alterations. However, little has been performed regarding phenotypic alterations of the precancerous lesions. We investigated the relationship among cellular proliferation, clonality, immortality and histopathologic grading of the squamous epithelial lesions of the uterine cervix. Proliferation index (PI) was calculated based on the ratio of the epithelial cells positive for proliferating cell nuclear antigen to the total epithelial cells. Clonality was assayed by X-linked HUMARA polymorphism. For immortality assay, PCR-based TRAP (telomeric repeat amplification protocol) was done and telomerase processivity was calculated by comparison with the positive control. PI increased gradually as the lesions advanced from dysplasia to invasive carcinoma. Among informative case, all of the carcinoma in situ showed monoclonal pattern (7 of 7). Among invasive squamous cell carcinoma, 6 cases showed monoclonal pattern and 2 cases polyclonal pattern. TRAP reaction was positive in 92.6% (25 of 27) of dysplasia (high grade: 14 of 15; low grade: 11 of 12), 95.0% (19 of 20) of carcinoma in situ, 100% (9 of 9) of microinvasive carcinoma, and 92.9% (13 of 14) of invasive carcinoma. It was also positive in 12 of 12 samples of chronic cervicitis or squamous metaplasia near the lesions of dysplasia. There was no difference in TRAP positivity among the dysplasia, carcinoma in situ and invasive carcinoma, whereas telomerase processivity showed significant correlation. These results suggest that proliferative activity and telomerase processivity may be progressive events in oncogenesis, although telomerase activation may be an early event.

BACKGROUND: Hypothermia is a condition that can lead to serious complications and even to death in newborn. Although the temperature control is essential in neonatal care, it is often neglected during urgent transfer from local private hospitals. The purpose of this study is to evaluate the incidence and clinical outcomes of transfer induced neonatal hypothermia. SUBJECTS AND METHOD: In this retrospective study, subject is limited to transferred outborn babies with age less than 24 hours from June 1996 to May 1999. A total of 3,086 patients were admitted in NICU during the study period and inborn and outborn babies were 1,743(56%) and 1,343(44%) respectively. Among the 1,343 outborn babies, 212 babies were transferred from the private hospital within 24 hours of birth and were eligible for the study. Rectal temperature on arrival, transfer time, birth weight, gestational age, initial arterial gas study, and clinical outcome were compared. Statistical analysis has been done with chi-sqaure test and multiple logistic regression analysis. RESULTS: There were 84 cases(39.6%) hypothermia(<36degrees C> among the 212 babies and the rate of hypothermia in transfered babies have not decreased over the study period. There were significantly more hypothermia in lower gestational age (less than 28 weeks) and lower birth weight (less than 2,000gm) caused hypothermia significantly more than normal gestational age or normal range of birth weight. And time interval (less than 12 hour) from birth to arrival at emergency department was also significant factor in hypothermia. The mortality rate was three fold higher in hypothermia than normothermic or hyperthermic babies. CONCLUSION: This study shows that hypothermia during neonate transportation is a major cause of neonatal mortality and morbidity in prehopital care. Body temperature control during transport of neonates under 24 hours of age should be emphasized for the better outcome of treatment.

We introduce an unusual case of acute myeloid leukemia (AML) showing strong myeloperoxidase (MPO) positivity without any lineage-specific cell surface marker expression, i.e. myelomonocytic antigens CD13, CD14, CD15 and CD33; or B-lymphoid antigens CD10, CD19, CD20, CD22 and surface immunoglobulin; or T-lymphoid antigens CD2, CD3, CD5 and CD7. The case was morphologically AML with maturation (FAB M2) and the cytogenetic study showed t (8; 21) (q22; q22) and missing Y. But Immunophenotypic studies by flow cytometry showed positive reaction ony for CD34 and HLA-DR. We considered this case as a 'presence of t (8; 21) in MPO (+), CD antigen (-) AML'. The myeloid lineage antigens are known to be expressed very early during myeloid differentiation whereas MPO (in its functional form) is viewed as being expressed relatively late in the process. Therefore, this case could be an example of 'asynchronous differentiation' in leukemia.

Mesoblastic nephroma is an important differential diagnosis of a renal mass occurring in the neonatal period or in early childhood. It is a rare monomorphous congenital renal neoplasm most commonly recognized during the first 3 months of life. With the widespread application of ultrasound imaging, many cases are recognized prior to birth. We report a case of mesoblastic nephroma detected by ultrasonograph at 36 weeks of intrauterine fetal life and removed after birth. It showed a well circumscribed, grayish white, solid mass measuring 4x3x2 cm. The tumor was predominantly a classic type with a focal cellular pattern. Immunohistochemical and electron microscopic studies were done.

The study was undertaken to asses the changes in the size and densities of intracranial hematomas by analyzingthe sequential CT examination of 23 patients ar Soon Chun Hyang College Hospital from July '80 to Aug. '81. Theresuls were as follows; 1. The high densities of hematoma were the cause of hematoma, hematoma locaiton, age andsex of patients, and initial hematoma size. 3. The CT findings that indicate complete absorption of hematomas werenormalization of mass effect, not diappearence of hematoma densities. 4. In intracerebral hematoma, the highdensity of hematoma reduced it's density and mass effect about 4-6 weeks duration. 5. In subdural hematoma, about7 weeks after head trauma, the CT findings were normalized.

BACKGROUND: Epidural anesthesia is thought to be relatively indicated for cesarean section in patients with severe preeclampsia. In contrast, avoidance of spinal anesthesia is recommended, postulating excessive hypotensive risks. In addition, general anesthesia is often avoided in this population because malignant hypertension following tracheal intubation is common and risks for difficult airway management are excessive. METHODS: In this study, we compared hemodynamic changes in patients with severe preeclampsia and normal pregnant women during spinal anesthesia for elective cesarean section. Spinal anesthesia was performed with 10 mg of 0.5% heavy bupivacaine mixed with 25 microgram fentanyl in 18 patients with severe preeclampsia and 17 normal pregnant women. We compared MAP, CI, and SVRI changes before and after spinal anesthesia. RESULTS: MAP responses following induction of spinal anesthesia for elective cesarean section in patients with severe preeclampsia and normal pregnant women showed a statistically significant decrease from 2 min after spinal anesthesia. CI responses following induction of spinal anesthesia in patients with severe preeclampsia showed a statistically significant increase from 8 min after and normal pregnant women also showed a statistically significant increase from 4 min after spinal anesthesia. SVRI responses from induction of spinal anesthesia in patients with severe preeclampsia and normal pregnant women showed a statistically significant decrease from 2 min after spinal anesthesia. Incidence of hypotension before delivery and used total dose of ephedrine during operation were statically insignificant between severe preeclamptic and normal pregnant women. CONCLUSIONS: We conclude that changes of MAP, CI and SVRI following spinal anesthesia for elective cesarean section in the severely preeclamptic and normal pregnant women are clinically similar. We suggest that spinal anesthesia for cesarean section is not contraindicated in the severely preeclamptic patient.

Acute hepatitis A is generally a mild, self-limiting disease of the liver. Acute renal failure is extremely rare in patients with acute non-fulminant hepatitis A. Acute tubular necrosis is the most common form of renal injury found in such patients. The 27 years old male patient visited our hospital with complaint of fatigue, nausea and vomiting. He was diagnosed with acute renal failure associated with acute non-fulminant hepatitis A. The renal biopsy demonstrates tubulointerstitial nephritis with focal tubular necrosis on light microscopy. We report here on a case of acute renal failure associated with non-fulminant hepatitis A, and we include a review of the literature.
