This study was undertaken to make current fetal growth curve throughout later part of pregnancy. 5,110 normal singleton deliveries at Il Shin Christian Hospital were included. The 10th, 25th, 50th, 75th, 90th percentiles of birth weight were calculated from 21 to 42 weeks' gestation and the 10th, 50th, 90th percentiles of birth weight compared by fetal sex, maternal parity and height were graphed to know the potency of factors. There was a linear growth pattern between 28 and 38 weeks' gestation. During last month of prgnancy, three factors have significant effect on median birth weight but no significant differences in 10th percentiles. Maternal height & parity significantly affeect on 90th percentiles. So, these factors must be considered when diagnosing large for date.

BACKGROUND: Oculocutaneous albinism (OCA) is a genetic disorder of the melanin pigment system in which melanin synthesis is reduced or absent in the skin, hair, and eyes. OCA is classified into two major types, and tyrosinase-related OCA can be produced by mutations of the structural gene for tyrosinase enzyme (TYR gene). OBJECTIVE: The purpose of this study was to analyze the segregation of mutant alleles of the TYR gene in tyrosinase-negative and tyrosinase-positive Korean OCA patients and families. METHODS: We amplified exon I, II, and III of the TYR gene of Korean OCA patients and their families by polymerase chain reactions (PCR), and analyzed the mutations by restriction fragment length polymorphism (RFLP) analysis in exon I and single-strand conformation polymorphism (SSCP) analyses in exon II and exon III. RESULTS: Two tyrosinase-negative cases showed mutations in exon I. Four tyrosinase-nega-tive cases and one tyrosinase-positive case showed mutations in exon II, and one tyrosinase-neg- ative case showed mutations in exon III. In summary, we found three kinds of mutation in four tyrosinase-negative OCA patients and one tyrsinase-positive OCA patient. CONCLUSIONS: RFLP and SSCP analysis can provide a basis for a rapid and sensitive screening system to detect TYR gene mutations of Korean OCA patients and their families.

Cerebral arterial embolism which resulted in total occlusion of right proximal middle cerebral artery was occured in 33 years old female patients with severe mitral stenosis and atrial fibrillation during percutaneous mitral balloon valvuloplasty(PMV). The occluded artery could be detected by transfemoral carotid angiography and recanalized immediately by intra-arterial infusion of urokinase. There were no cerebral hemorrhage by CT scan after intra-arterial urokinase infusion and the patients discharged without any neurologic sequale 7 days after thrombolysis. We report a case of successful recanalization with intraarterial infusion of urokinase in patient with cerebral arterial embolism occurred during PMV.

PURPOSE: A scaphoid fractures (SF), an important injury with acute pain, may not be diagnosed on the initial X-rays in the emergency department. Some authors have suggested that several clinical examinations are necessary to reliably confirm the presence of a fractured scaphoid in those patients presenting with an injury clinically suggestive of such a fracture, but without a fracture visible on the initial Xrays. we performed this prospective study to evaluate the efficacy of clinical signs believed to be useful in the diagnosis of a SF. METHODS: We performed a 1-year prospective study on 127 patients with suspected SFs. They were examined on two separate occasions : first in the emergency department and then in the outpatient clinic of the orthopedic department 2 weeks later. Tenderness in the anatomical snuff box (ASB), tenderness over the scaphoid tubercle (ST), and pain on longitudinal compression with the thumb (LC) were evaluated. RESULTS: At the initial examination, the ASB, the ST and LC were all 100% sensitive for detecting a SF with specificities of 40%, 49%, and 59%, respectively. These clinical signs, used in combination within the first 24 hours following injury, produced 100% sensitivity and an improvement in the specificity to 76%. Ninety-one (91) patients had one or more of positive clinical tests, with 18 of those patients having a SF visible on the initial X-ray and five having a fracture diagnosed either by repeated X-ray or CT 2 weeks after the injury. CONCLUSION: Our results suggest that the clinical signs ASB, ST, and LC are inadequate indicators of a SF when used alone and should be combined to achieve a more accurate clinical diagnosis.

The aim of this study was to identify factors that predict morbidity and mortality in patients with traumatic pancreatic injuries. A retrospective review was performed on 75 consecutive patients with traumatic pancreatic injuries admitted to the Emergency Medical Center at Masan Samsung Hospital and subsequently underwent laparotomy during the period January 2000 to December 2005. Overall mortality and morbidity rates were 13.3% and 49.3%, respectively. A multivariate regression analysis revealed that greater than 12 blood transfusions and an initial base deficit of less than -11 mM/L were the most important predictors of mortality (p<0.05). On the other hand, the most important predictors of morbidity were surgical complexity and an initial base deficit of less than -5.8 mM/L (p<0.01). These data suggests that early efforts to prevent shock and rapidly control of bleeding are most likely to improve the outcome in patients with traumatic pancreatic injuries. The severity of pancreatic injury per se influenced only morbidity.

Gartner duct cysts are relatively common congenital cysts in the anterolateral wall of the vagina. Most are small (less than 2 cm) and asymptomatic, but larger cysts may cause problems. We report a rare case of a giant Gartner duct cyst (7 cm) originating from the right lateral portion of the uterine cervix and adjacent myometrium. It appeared as an exophytic multiseptated cystic mass containing different density fluids on CT.

Ionized hypocalcemia is a common finding in critically ill patients, but the relationship between ionized hypocalcemia and mortality risk in trauma patients has not been well established. The aim of this study was to assess the usefulness of initial ionized calcium (iCa) in predicting mortality in the trauma population, and evaluate its superiority over the three other triage tools: base deficit, systemic inflammatory response syndrome (SIRS) score, and triage-revised trauma score (t-RTS). A proand retrospective study was performed on 255 consecutive trauma patients admitted to our Emergency Medical Center from January to December, 2005, who underwent arterial blood gas analysis. Multivariate logistic regression analysis confirmed iCa (< or =0.88 mM/L), low Glasgow coma scale score, and a large transfusion amount to be significant risk factors associated with mortality (p<0.05). The sensitivities of iCa, base deficit, SIRS score, and t-RTS were 82.9%, 76.4%, 67.1%, and 74.5%, and their specificities were 41.0%, 64.1%, 64.1%, and 87.2%, respectively. Receiver operating characteristic curve analysis determined the areas under the curves of these parameters to be 0.607+/-0.062, 0.736+/-0.056, 0.694+/-0.059, and 0.875 +/-0.043, respectively (95% confidence interval). Although initial iCa (< or =0.88 mM/L) was confirmed as a significant risk factor associated with mortality, it exhibited a poorer discriminative power for mortality prediction than other predictors, especially t-RTS.

PURPOSE: The purpose of this study was to review our clinical experiences of acute mesenteric ischemic disease at the Masan Samsung hospital. METHOD: Retrospectively reviewed the medical records of 20 patients with acute mesenteric ischemic disease from 1998 through 2003 in terms of clinical characteristics, image findings, management and results. RESULT: The mean age of patients was 63.5 years and the male female ratio was 1.5:1. Coexisting diseases were atrial fibrillation (n=10), hypertension (n=9), myocardial infarction (n=2), DM (n=4). The clinical manifestations were abdominal pain, abdominal distension, peritoneal irritation signs, vomiting and melena. The presenting signs were nonspecific. Laboratory findings were nonspecific and not helpful for diagnosis of acute mesenteric ischemia. Abdominal CT and SMA angiography were accurate and sensitive diagnostic tools. Seventeen cases were SMA occlusion (1 case: SMA dissection) and 3 cases were SMV occlusion. Operative procedures were resection of bowel (12 cases) and thromboembolectomy (5 cases). Non operative procedure was anticoagulation (3 cases). One patient refused surgery. CONCLUSION: Both clinical and laboratory data were non-specific and delayed diagnosis was the main cause of the overall mortality rate of 35% (7 cases). The mortality rate for patients undergoing surgery for acute mesenteric ischemic disease was high, but early diagnosis and intensive care may be reduced mortality.

To determine the content of thyroglobulin in oxyphilic cells of the thyroid, which have been considered as non-thyroglobulin producing cells, the degree of stainability of the various oxyphilic cells for thyroglobulin was compared with that of non-oxyphilic follicular cells in either same or different lesion. A total of 13 oxyphilic lesions, including three follicular adenomas containing oxyphilic cell nodules, four pure oxyphilic cell adenomas, and six Hashimoto's thyroiditis were compared with 16 of non-oxyphilic lesions such as, seven follicular adenomas, four chronic lymphocytic thyroiditis, and five Graves' disease. Many oxyphilic cells stained positively for thyroglobulin regardless of their morphologic variation, but less intensely than the usual follicular cells in follicular adenomas, chronic lymphocytic thyroiditis, and Graves' disease. The stainability of oxyphilic cells for thyroglogulin did not show any significant correlation with morphologic features, whereas in follicular adenomas, the non-oxyphilic follicular cells forming microfollicles stained less strongly for thyroglobulin than the same cells lining large mature follicles in a reproducible way. With above findings, we concluded that oxyphilic cells maintain the functional activity in terms of thyroglobulin synthesis, although the content of the thyroglobulin is less than that of non-oxyphilic colloid forming follicular cells.

PURPOSE: We wanted to analyze the citation trend and to find a way to improve the impact factor (IF) of the Journal of the Korean Radiological Society (JKRS). MATERIALS AND METHODS: The number of articles and references, the total citations and self-citations, the IF and the IF excluding self-citations (ZIF) were described by an analysis of Korean Medical Citation Index (KoMCI) during 2000-2005. The total and self citations of the JKRS were compared to that of the Top 5 journals. RESULTS: There was a 57% decrease of papers for 6 years. The Korean references/paper ranged from 0.98-0.85. The number of total citations received steadily decreased from 394 in 2000 to 180 in 2005. The IF (ZIF) of the JKRS has been gradually lowered from 0.142 (0.049) in 2000 to 0.063 (0.059) in 2005. Although the total citations that cited all papers published/the annual number of papers was 55% of that of the top 5 journals, the total citations citing papers published within the recent two years was only 24% of that of the top 5 journals. CONCLUSION: The citation status of the JKRS hassteadily decreased for the recent 6 years, and the IF of the JKRS was very low among all the Korean medical journals. To improve the IF, active advertising for the journal members of the importance of the IF is needed to encourage citing JKRS papers that have been published within the recent two years.
