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.

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.

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.

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.

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.

PURPOSE: The purpose of this study was to understand the principle of percutaneous nephrolithotomy(PNL), toincrease its success rate, and to base the radiologic approach on preoperative interventional tract dilatation. MATERIALS AND METHODS: Twenty-six patients(male, 19, female, 7) with staghorn or pelviocalyceal calculi who hadundergone PNL were included in this study. After percutaneous nephrostomy(PCN) was performed in each patient, thetract was dilated to 30F with Amplatz dilators using coaxial techniques or a 30F, 10cm high-pressure tractdilatation balloon. One day before the calculi were fragmented and removed by PNL, a 30F Amplatz sheath wasinserted under local anesthesia. The time required for tract dilatation, complications, and surgery was analyzed. RESULTS: Percutaneous tract dilatation were successful in all patients, and forceps, a nephrolithotome and anephroscope were successfully introduced into the pelvocalyceal system. The average procedure time was 19.5minutes ; a double J stent was replaced in the pelvocalyceal system of 13 of 26 patients (50%) ; because ofimproper catheter direction or/and bleeding, the Amplatz sheath was replaced in three. After PNL, complicationsinvolving renal hematoma occurred in one patient. This did not affect the patient's prognosis, however. CONCLUSION:Owing to its short procedure time and low complication rate, interventional preoperative tract dilatation forPNL is thought to be an effective technique for patients with staghorn or pelvocalceal calculi.

The reconstruction after radical vulvectomy presents a difficult challenge. Ideal flap for vulvoperineal reconstruction has thin character, constant vascular supply, and presents concealed scar after reconstruction. Various flaps are used for reconstruction of the vulvar area, have their own advantages and disadvantages. The authors performed 15 vulvoperineal reconstructions using three kinds of different 28 fasciocutaneous flaps. Gluteal fold fasciocutaneous island flap seems like labia major and remains concealed donor scar along the gluteal fold. But secondary debulking procedure is sometimes required. Vulvoperineal V-Y advancement fasciocutaneous flap is thin, reliable, easily elevated, and matches with regional skin quality, but donor site scar is conspicuous on medial thigh. Gluteal fold V-Y advancement fasciocutaneous flap is also reliable, easily elevated, and matches with regional skin quality with thin flap and concealed donor scar on gluteal fold. Also, it can be advanced even a long distance. Through our experiences, these flaps are very useful for vulvar reconstruction, but in the aspect of donor site scar, thickness, and degree of advancement, gluteal fold V-Y advancement fasciocutaneous flap is superior to the other two patterns for the reconstruction of the large sized vulvoperineal defect.
