Basal cell epithelioma arising from epidermis and its appendages is a common skin tumor. But multiple occurence of basal cell epitheliomas and that of arising in an epidermal nevi are extremely rsre. Since the first report by Toyama and Kojima in 1937, only few cases were reported in the world literatures. We observed a case of multiple basal cell epitheliomas arising in an epidermal nevi in a 54-year-old female patient who had rhomboidal verrucous patch on the right side of the cheek and arciform erythematous verrucous eruption from the right side of the eyebrow to the lower eyelid. Clinical features were not compatible with any type of basal cell epithelioma. But histological finding revealed basal cell epithelioma with epidermal nevi. Literatures were briefly reviewed.

We report a case of hypertrophic lupus vulgaris in the right knee of an 18-year-old man. The lesion, an erythematous scaly hypertrophic plaque, had grown for 12 years without any trestment leaving an atrophic scar. Histopathologically, the lesion consisted of s granuloma composed of epithelioid cells and lymphocytes. Lsboratory examinations including hematology, blood chemistry, urinalysis, and chest roentgenography were normal. The Mantoux test was strongly positive. Treatment with anti-tuberculosis medieation resulted in a good response.

The epidemiology of children with cortical visual impairment(CVI)has been poorly defined till now, so the purposes of this study were to define the visual prognosis and prevalence of ophthalmologic problems in Korean children. The 20 children with follow-up of over 3 months were included out of 24 children diagnosed with CVI. The causes of CVI were periventricular leukomalacia in 7, congenital malformation in 4, and cerebral infarct or atrophy. Twelve of 19 children who had visual impairment at their initial visit showed visual improvement with follow-up. There were strabismus in 14, nystagmus in 6, and abnormal optic disc in 8 of the 20 children. All visualevoked response results were abnormal, but were not providing a more reliable prognosis in vision. The children who had abnormal electroencephalogram had poor visual prognosis as well as delayed developmental level. In conclusion, this study identified that children with CVI may be presented with a variety of ocular abnormalities, including strabismus, nystagmus, and abnormal optic disc. These findings suggest that a better understanding of the natural course will be required in children with CVI.

To evaluate the effect of tibial cut with posterior slope in total knee arthroplasty(TKA) surgery on the flexion of the knee, 41 knees(32 patients) with varying degree of the posterior slope were retrospectively reviewed at more than 1 year after operation. Does sloping the tibial cut iurface rnore posteriorly promote increasing of maximal flexion of the knee by elimination of excessive tenaion of the posterior cruciate liga ment The degree of the posterior slope was radiographically measured, awi the change of the degree of the maximal flexion between preoperative and postoperative period was clinimlly measured with a goniometer at the latest follow up more than 1 year after operation. Comparison of the results demonstrated significantly larger degree of rqaximal flexion for the knees that had tibial cut with the degree of the posterior slope, 5 degrees or rnore (p<0.05). We concluded that 5 degrees or more posterior slope in proxirnal tibial cut is one of the important fact()r which could achieve increased flexion of the knee after TKA operation.

OBJECTIVE: To identify and localize the Placenta Growth Factor (PlGF) mRNA in term placentas and to determine whether there are any differences in the expression of PlGF mRNA in the placentas between normal and preeclamptic pregnancy. METHODS: Northern blot and In situ hybridization with 5 cases of preeclamptic placentas and 8 cases of normal controls RESULTS: In Northern blot analysis and In situ hybridization, PlGF2 mRNA (1.7 kb) band was identified and showed significant decrease in density in preeclamptic placentas compared to that of normal controls. PlGF mRNA was mainly expressed in the syncytial membrane of villous trophoblast, and in the perivascular tissue surrounding the vasculature of stem villi. CONCLUSION: Decreased levels of PlGF mRNA in preeclamptic placentas could have some unfavorable influences on trophoblast and endothelial function, thereby may play a role to the pathogenesis of preeclampsia.

Ibandronate (a bisphosphonate) is commonly used as an treatment of osteoporosis in combination with vitamin D. Monthly DP-R206-a novel, fixed-dose combination tablet (150 mg ibandronate/24,000 IU vitamin D3)-was recently developed to enhance patient compliance. This open, randomized, two-period crossover study was conducted to compare the pharmacokinetics of ibandronate when administered as DP-R206 or 150 mg ibandronate to healthy adult volunteers. Each volunteer was randomly allocated to receive single-dose DP-R206 or ibandronate with a 28-day washout period between treatments. Blood samples were assessed using pharmacokinetic analysis. Plasma ibandronate concentrations were determined using liquid chromatography-tandem mass spectrometry. Safety and tolerability assessments were performed throughout the study. In total, 103 participants received the study drugs and 72 participants completed the study. The geometric mean ratios (DP-R206/ibandronate) of the maximum concentration (C(max)) and the area under the plasma concentration time curve from time zero to the last concentration (AUC(last)) values were 0.959 (90% CI: 0.820-1.120) and 0.924 (90% CI: 0.805-1.060), respectively. The frequencies of adverse events (AEs) and drug reactions were similar between treatment groups, and all AEs were recovered without sequalae. Ibandronate pharmacokinetics, tolerability, and safety are comparable when administered to healthy individuals, regardless if administered as DP-R206 or ibandronate.

BACKGROUND: Cerebral ischemia causes an increase in extracellular potassium ([K+]e) through activation of the KATP channel. This increase in [K+]e could result in neuronal depolarization and a reversal of the glutamate uptake system in glia. This may further contribute to the excessive concentrations of glutamate and asparate in the extracellular space during ischemia. If the early rise in [K+]e during ischemia could be attenuated, less excitotoxic neuronal damage may be the result. However, activation of KATP channels has been shown to attenuate the anoxia induced depolarization in the hippocampus and may reduce the release of excitatory neurotransmitters during cerebral ischemia. In this study, we address the question of whether KATP channel modulation affects [K+]e and whether it is related with extracellular glutamate concentrations. METHODS: After approval by the Animal Care and Use Committee, 18 New Zealand white rabbits were anesthetized with halothane and mechanically ventilated to maintain normocarbia. Microdialysis catheters were inserted into the left dorsal hippocampus and perfused with artificial cerebrospinal fluid at 2 ml/min. K+ sensitive microelectrodes were inserted into the contralateral hippocampus. A pneumatic tourniquet was placed loosely around the neck. Animals were randomized to receive glibenclamide (n=5, KATP blocker, 3.7 mg/kg) or cromakalim (n=5, KATP opener, 0.5 mg/kg). The control group (n=6) had neither drug. Ten-minute period of global cerebral ischemia was produced by inflation of the tourniquet combined with induced hypotension. Hippocampal [K+]e was measured throughout the periischemic period and glutamate concentrations in dialysate were determined by high-performance liquid chromatography. Peak levels were compared by ANOVA. RESULTS: Glutamate concentration significantly increased during ischemia period for all groups (p<0.05). In glibenclamide treated animals, brain glutamate concentration increased markedly during early reperfusion (t=I+15) compared to other groups (p<0.05). There were no statistical differences on ischemia-induced increases in [K+]e among the three groups. CONCLUSIONS: Although it was not possible to demonstrate an effect of modulators of the ATP sensitive K+ channel on [K+]e, glibenclamide increased glutamate during reperfusion. This paradoxical increase in glutamate after administration of a K+ channel blocker suggests that the mechanism of glutamate release is not related to [K+]e change.

The facial patterns were expressed by the interrelation of variable factors such as heredity, function and environment. Such variable factors have an effect on the growth and development of maxillofacial bones. The malocclusions with skeletal discrepancies are caused by abnormal forms, sizes and positions of cranial base, maxilla and mandible. For the proper diagnosis and treatment planning, the analysis of such structures is necessary. Lateral cephalograms of 54 adults with class III malocclusion patients (test group) and 61 adults with normal occlusion (control group) were analyzed. Anteroposterior relations and sizes of cranial base, maxilla, mandible were estimated to compare with those of normal ones. In test group, the anterior cranial base length was within normal range, but posterior cranial base, maxilla and mandibular body were longer than those in control group, significantly. Based on the cranial base, the location of maxilla in test group was normal, but the location of mandible was more anterior than that in control. Based on the maxilla, the location of mandible was more anterior in test group than that in control. Both mandibular body and ramus anteroposterior lengths in test group were larger than those in control. Both mandibular plane angle and upper gonial angle were within normal range, but lower gonial angle was significantly high in test group.
