Apert described acrocephalosyndactyly as a clinical entity in 1906. At first he included a patient with craniofacial deformities combined with syndactyly of both the upper and lower extremities. This is a rare congenital disturbance in the growth of bone and soft tissue affecting principally the head, the hands and the feet. More than 200 cases have been reported in the world literature, and three cases in Korea. Authors experienced one case of the classic pattern of Apert's syndrome and treated surgically for syndsctyly.

The most important aspect of the imaging role for indeterminate bile duct stricture is to make a differential diagnosis on whether the stricture is highly likely to be malignant or benign. Compared to benign stricture, malignant stricture is longer, thicker, and has indistinct outer border and irregularity of the lumen in contrastenhanced computed tomography and magnetic resonance (MR). Also, in the contrast-enhanced portal phase, malignant stricture has a stronger enhancement than the liver parenchyma. There are studies to differentiate between malignant and benign stricture in diffusion weighted image, a functional MR image, but there remains controversial. Sometimes, malignant biliary stricture may be caused by bile duct invasion of gallbladder cancer, pancreatic cancer, hepatocellular carcinoma, biliary metastasis, and lymphoma. Among the potential causes of indeterminate biliary stricture, the characteristics of multifocal biliary stricture mainly suggest benign sclerosing cholangitis, and various external compression factors that cause biliary stricture can be differentiated by radiologic imaging. There are causes of biliary dilatation without obstructive lesion, radiologic diagnosis can be made by considering various characteristics.

BACKGROUND: Recently, inireaing numbers of chemotherapeutic agens are being used to treat cancer patients. Mucocutaeous complications are commonly sen in association with the administration of these medicaticins. OBJECTIVE: We conducted a study in cancer chemotherapy patient so determine the suspected chemotherapeutic agents ancl frequency of various mucocutaneous side effects in these patients. METHODS: The study involved 140 patients admitted from Decerrae 1993 to September 1994 for cancer chemot herapy at Korea University Guro Hospital. RESULTS: The mucocutaneous side effects during chemotherapy were alopecia(55%), hyperpig mentation(32.9%), stomatitis(20%), phlebitis(12.9%), flushing(8.6%) descending order. Visual grade II, IV alopecia patients were most common, but as the chemot retpy cycle increased so, the severer the alopecia. Although the onset of the alopecia were variake many patients experienced alopcia within 17 to 24 days after the start of chemotherapy. Serpeitie supravenous fluorouracil hyperpigmentation were commor,(17.9%), Diffuse and longitudinal or horizontal band like nail pigmentation were observed, and, pigmented macules were also observei, epecially on the palms and digits. Stomatitis usually developed within 10 days after the start of chemotherapy and it persist ed for about 7 days and the most of the lesions were resolved spor Laeously. Other clinical manifestations accompanied with chmotherapy were tinea infection(16.4%), acne(7.1%), oral thrush (7%), white nail band(4.3%), pruritus(2.9%) in descending order. CONCLUSION: So, physiciars need to be aware of the widely divergnal cutaneous reactions which may occur with the use of antiancer medications.

PURPOSE: We investigated the effect of anticholinergic drug treatment before midurethral sling surgery in patients with mixed urinary incontinence(MUI). MATERIALS AND METHODS: Between January 2004 and December 2006, 112 female patients with MUI were evaluated. Forty-seven patients were not medicated with anticholinergic drugs(Group A) and 65 patients were medicated with anticholinergic drugs(Group B) for 2 weeks or more(2-8 weeks, mean 2.34+/-1.02) before the midurethral sling operation. After the midurethral sling operation, the patients were followed up for 4 weeks or more(4-48 weeks, Group A is 7.83+/-8.70, Group B is 6.77+/-7.58). Cure of the incontinence after the procedure was defined as the absence of subjective symptoms such as frequency, urgency, urge incontinence and the absence of objective leakage on stress testing. All other cases were considered failures. RESULTS: There were no significant differences between the group that was not medicated preoperatively (Group A) and the group that was preoperatively medicated(Group B)(cure rate of Group A was 87.2% and Group B was 89.2%, p=0.745) in the cure rate for pure stress urinary incontinence. However, comparison of the postoperative results for the MUI showed significant differences (cure rate of Group A was 63.8% and Group B was 81.6%, p=0.035). The cure rate was significantly higher in the preoperatively medicated patients than in the patients who were not preoperatively medicated with regard to the MUI. CONCLUSIONS: Our findings suggest that treatment with anticholinergic medications before a midurethral sling operation improves the cure rate in patients with MUI.

The goal of cleft lip surgery is to reconstruct normal shape of the lip. To acomplish this goal, various operative method were contrived and concept of the method decided the shape of reconstructed lips. According to the operative result, some operative methods were disappeared or have been developed with a little modifiation. Traditional Millard's rotation-advancement method for unilateral cleft lip patients is largely accepted and developed as proper method for acquiring these functional and anatomic purposes. As a trial for this development, Mulliken add some modifications. He uses exaggerated high rotation incision and it lengthens into midcolumella without backcut. Also he dosen't steal from alar base or lateral lip for vertical height. C-flap is used to lengthen the affected columella and upper lip. The isolated orbicularis oris muscle is coaptated each other for more functional result. With supraperichondral dissection of alar cartilage and transpositioning of caudal septum, he performs synchronous repair of cleft lips, nose and sometimes alveolus. It is still debated when is most suitable age for surgical correction of nasal deformity of cleft lip patients. Done at the time of primary lip repair, there are both some apprehension and inducement. The former are based on technical difficulties due to shortage and fragility of neonatal tissue and possibility of progressive deformities with growing because of iatrogenic injuries to the alar cartilages. But te latter is rationalized because early reposition of deformed nasal cartilage in proper position would induce more natural growth of nasal structures. Some long-term follow up reports reveal the early operation innocent of any growth deterioration. Mulliken treats his cleft lip patient for separated lip and nasal deformities with single operation, and does gingiovoperiosteal alveoloplasty at the same time if necessary. He uses Latham appliance from 4 to 6 week after birth in case of severly collapsed lateral alveolar segment or wide alvolar gap, and perform the definitive opertation at the age of 4 to 6 months. I use lip adhension method to correct more than 10 mm alveolar gap without severe collapse of lateral alveolar segment, but if lateral segment was severely collapsed and away from alvolar arch, I apply the Latham appliance somewhat modificate from original type, which has a metal ring fastened at the front limb of appliance for rubber banding to coaptate easily. I have experienced repair of cleft lip by Mulliken's concept with some modification of my own to 44 cases of unilateral cleft lip patients and conclude that it was very flexible method. Doing with synchonous repair of cleft lip nose, we could get harmonious lip and nose with symmetric nostril sill, cupid's bow and red line. Columella was lengthened primarily. Normal growth of nose was anticipated by anatomic repositioning of alar septal cartilage.

Capsule contraction syndrome is severe constriction of the anterior capsular opening and equatorial capsular bag diameter after extracapsular cataract surgery. It is relatively common in patients with continuous curvilinear capsulorhexis, but rarely in can-opener capsulotomy or anterior radial capsular tears. It is due to capsular bag contraction from fibrous dysplasia of residual lens epithelial cells with weakened zonular resistance. We experienced a case of capsule contraction syndrome in a 72-year old woman with retinitis pigmentosa, who had phacoemulsification following an intact 5.0mm-continuous curvilinear capsulorhexis 4 months before. After successful YAG laser radial anterior relaxing capsulotomy, her visual acuity restored to 0.3, limited by cystoid macular edema.

BACKGROUND: The renin angiotensin syaimstem plays an important role in hypertension. Therefore, the purpose of this study was to investigate the comparison of responsiveness to angiotensin II (ANG II) in isolated renal proximal convoluted tubules of spontaneously hypertensive (SHR) and Wistar Kyoto (WKY) rats. METHODS: Intracellualr calcium concentration ([Ca2+i) was measured using Fura- 2/AM, inositol trisphosphate (IP3) accumulation was determined by radioimmuno assay and cellular ATP content measured using the microchemilunescene method in renal proximal tubule suspension or isolated renal proximal tubules. RESULTS: When measured the ANG II-induced [Ca2+i, the young rats showed a greater response to ANG II than adult rats in both strains. The ANG II (10-7 M)-induced [Ca2+i transient in the cortical tubule suspension from adult SHR was significantly lower than that in age-matched WKY. In isolated proximal tubule segments, ANG II-induced [Ca2+i increment was only observed in S1 segments. Comparing responsiveness to ANG II in SHR and WKY, similar phenomenon was observed as experiment using tubule suspension. IP3 accumulation by ANG II also attenuated in adult SHR. The 20-minutes incubation without any exogenous substrate in proximal convoluted tubule (S1) significantly decreased cellular ATP content and ANG II (10-7 M) inhibited decrement of cellular ATP level. The effect of ANG II on cellular ATP restoration was disappeared by the treatment with losartan. CONCLUSION: From these results, the responsiveness of ANG II to AT1A receptor is attenuated in the proximal convoluted tubules of adult SHR comparing the age- mached WKY.

Squamous cell carcinoma(SCC) is a recognized late complication of chronic discoid lupus erythematosus(CDLE). There are many case reports of SCC in white patients with chronic DLE. However, it is uncommon in blacks and Asians. The etiology of squamous cell carcinoma is multifactorial. The predisposing factors for the development of SCC in these patients include actinic keratosis, Bowen's disease, burn scars, arsenic keratosis, and chronic discoid lupus erythematosus. Of these causes, SCC developing in the lesions of CDLE is very rare. We report a patient who has been evaluated for ten years with a diagnosis of discoid lupus erythematosus and has squamous cell carcinoma.
