OBJECTIVE: The measurement of liver size can be used for the diagnosis of the fetal growth abnormality (FGR, macrosomia etc.). The purpose of this study was to evaluate a mathematical relationship between the fetal liver size(liver length or volume) and the gestational age in the normal pregnancies. Brief comparisons were also tried on the base of the degree of the correlation between liver length and its volume. METHODS: We collected 54 singleton pregnancies of 20 to 36weeks of gestation for measuring fetal liver length and 57 singleton pregnancies for measuring fetal liver volume. We used Combison 530 utrasonic machine(Kreztechnik AG, Zipf, Austria). RESULTS: There was significant correlation between liver size( length and volume) and gestation age. And the liver volume better correlated with gestational age than liver length(r=0.93 : r=0.78, p<0.0001, p<0.0001). CONCLUSION: Ultrasonic measurement of fetal liver size is a reliable indicator of fetal growth, especially liver volume. Therefore these data may have a potential value for the prediction of abnormal fetal growth(FGR, macrosomia).

OBJECTIVES: To understand the importance of the serum level of Ca-125 among pelvic mass, we performed a study. METHOD: From January to December 1998, we performed the study. Before hysterectomy, we performed a blood sampling to know the serum level of Ca-125, After hysterectomy, we weighed the uterus and measured the thickness of endometrium and other histologic characteristics. RESULTS: We performed my research to 80 peoples. The relation between uterine weight and the serum level of Ca-125 is little, if ever(R2=0.0007), and the relation between the thickness of endometrium and the serum level of Ca-125 is also little, if ever(R2=0.0353). The relation between leiomyoma, the cycle of endometrium and the serum level of Ca-125 were also little, but there was a close relationship between adenomyosis and the serum level of Ca-125. CONCLUSION: There was little relationship between uterine weight and the serum level of Ca-125.

Eccrine poroma is a benign neoplasm, whicn is thought to originate from the eccrine sweat gland. Previous studies suggest that these are primarily lesions of the hairless acral surface. We report a clinicopathological case of a 30-year-old man who presented with a 2.0 by 1.2 cm sized, unusual scalp lesion, which proved to be an eccrine poroma. There has been no local recurrence in the 4 months since complete excision.

BACKGROUND: Human skin is exposed to various environmental stresses, such as heat, cold, and ultraviolet (UV) radiation. Heat shock proteins (HSPs) induced by temperature elevations, as a physiologic response to mediate repair mechanisms and reduce cellular damage. OBJECTIVE: The purpose of this study was to investigate the induction of HSPs in human skin cells after UV exposure. METHODS: We performed immunoblotting using a specific monoclonal antibody to the HSP70 family, one of the best-conserved stress proteins in humans, with cultured normal human keratinocytes, A431 cells, human melanocytes, SK30 cells, and human dermal fibroblasts (HDF). RESULTS: Our results indicated that high expression of HSP70 in the unstressed state was noted in epidermal cells, including normal human keratinocytes, A431 cells, human melanocytes, and SK30 cells, but epidermal cells showed no additional up-regulation of HSP70 after UV irradiation. On the other hand, HDF expressed very small amounts of HSP70 at baseline, but significantly higher amounts of HSP70 after UV exposure. CONCLUSION: These findings suggest that constitutive expression of HSP70 in epidermal cells may be an important mechanism for protection of the human epidermis from environmental stresses, such as sunlight exposure.

Steatocystoma multiplex is a hamartomatous malformation of the pilosebaceous junction. It is thought to be hereditary or non-hereditary and rarely occurs on the face. We report a case of steatocystoma multiplex located only on the forehead of a 98-year-old woman. Histologic examination revealed a folded cyst wall consisting of several epithelial layers and flattened sebaceous gland lobules close to the cyst wall, which are relatively typical findings of steatocystoma multiplex.

BACKGROUND: Pemphigus vulgaris is an autoimmune bullous dermatoses of skin and mucosa characterized by loss of adhesion between keratinocytes, a process known as acantholysis. Apoptosis, programmed cell death, may participate in pathogenesis of intercellular detachment and loss of cell-matrix interaction. OBJECTIVE: This study was designed to investigate the induction of apoptosis in the pemphigus lesional epidermis and to elucidate the mechanism of apoptosis induced by pemphigus sera. METHODS: Hoechst 33342 staining was performed to determine the induction of apoptosis in the pemphigus lesional epidermis. In addition, we used HaCaT cells treated with pemphigus sera and analyzed the expression of caspase-3, caspase-8, caspase-9 and bcl-2, bcl-xL, bax, bak by the RT-PCR method. RESULTS: In Hoechst 33342 staining, typical findings of apoptosis were observed in the pemphigus lesional epidermis showing acantholysis. RT-PCR showed the upregulation of caspase group (caspase-3, caspase-8, caspase-9), the downregulation of antiapoptotic bcl-2 family (bcl-2, bcl-xL) and the upregulation of proapoptotic bcl-2 family (bax, bak). CONCLUSION: These results suggest that apoptosis may be associated with acantholysis of pemphigus lesional epidermis and may play an important role in the pathogenesis of pemphigus.

BACKGROUND: Intracranial complications of paranasal sinus infection are rare and may be misdiagnosed during an initial evaluation because they often show subtle symptoms, which include elusive physical and neurological findings and imaging. The late recognition of these conditions and the delayed treatment can increase morbidity and mortality rates. We aimed to characterize the typical clinical features of intracranial complications associated with sinusitis. METHODS: Twelve patients who visited the Eulji Medical Center from 1994 to 2000, with sinogenic suppurative intracranial lesions were reviewed. Medical records and radiological studies were reviewed retrospectively. RESULTS: There were 12 cases with 15 sinogenic intracranial complications. The ratio of males to female was 2 : 1. The ages of patients ranged from 16 to 81 (average: 46.7). Four cases had meningitis, four had focal cerebritis, three had cavernous sinus throm-bophlebitis, two had subdural empyema, and two had epidural abscess or empyema. The primary lesions of paranasal sinusitis were located at the sphenoid in three, ethmoid sinus in two, frontal sinus in one and the multiple sinus in six. The outcome revealed complete recovery in six cases, mild neurologic sequelae in three cases, death in two cases and recurrence in one case. CONCLUSIONS: The type of intracranial complication and origin of paranasal sinusitis may be changing. Cases in which such complications are suspected, in order for an early diagnosis, a MRI should be considered. The successful management of intracranial complications consists of timely antibiotics therapy combined with surgical drainage of the loculated infection. (J Korean Neurol Assoc 19(5):457~463, 2001)

Hobnail hemangioma is a benign vascular tumor that typically presents as a small, single lesion on the skin of the trunk or limb. It occurs mainly in young or middle-aged adults (mean age: 30 years) but rarely in childhood. Histologically, hobnail hemangioma is characterized by a biphasic growth pattern, with dilated vascular spaces lined by hobnail endothelial cells in the superficial dermis, and collagen dissection narrow vascular channels in the deeper dermal parts, as well as inflammatory aggregates, fibrosis, and hemosiderin deposits. We report a case of hobnail hemangioma in a 10-year-old girl who had a violaceous papule surrounded by an ecchymotic halo on the left thigh. She underwent treatment with surgical excision with primary closure. To the best of our knowledge, our case is the first reported case of childhood hobnail hemangioma in Korean dermatological literatures.

OBJECTIVE: Our purpose was to investigate the distribution of the result of 17,744 cervicovaginal smears and their pathologic results in Inha University Hospital to make a reference data. METHODS: During 28 months, May 1996 to August 1998, we performed 17,774 cervicovaginal smears and arranged them by the Bethesda system and compared them with their pathologic results. RESULTS: Among 17,744 smears, there were 93.2% of benign results, 2.9% of ASCUS, 0.9% of LSIL, 1.4% of HSIL, and 0.8% of SCC. The ASCUS/SIL ratio was 1.28. Among ASCUS, the high grade histologic outcome was composed 4.0%. Among LSIL, there were 15.7%, and HSIL 48.0%, SCC 56.1%, AGUS 9.3%, and Adenocarcinoma, the results was 69.2%. CONCLUSION: Among 17,744 smears, there were 93.2% of benign results, 2.9% of ASCUS, 0.9% of LSIL, 1.4% of HSIL, and 0.8% of SCC. The ASCUS/SIL ratio was 1.28. These results were very similar to other data and we would like to add our data to them as a reference. And the worse the smear results were, the worse the pathologic results were.
