It is not uncommon that an endoscopist should differentiate metastatic or invasive cancer to the colorectum from primary colorectal cancer with its endoscopic appearances. This study reviewed the endoscopic appearances of 7 patients who were proved to have metastatic or invasive cancers to the colorectum, both clinically and pathologically. The primary cancers were uterine cervix cancers in 3 patients, advanced gastric cancers in two, and prostatic cancer in one. The endoseopic appearances of metastatic or invasive cancer showed several characteristic features with regard to those of primary colorectal cancer, as follows. 1) Multiplicity of lesions 2) Nodular lesion with unaffected mucosa or with mild degree of erosions 3) Concentric defarmities with conical extremities and the absence of shelving margins 4) Inflammatroy lesions with mucosal hyperemia, erosion, ulceration, and bleeding, but without definite mass formation.

PURPOSE: We performed this study to evaluate the alterations in renal function for patients with ileal conduit and ileal orthotopic neobladder MATERIALS AND METHODS: From January 1999 to June 2004, 48 patients who had undergone radical cystectomy with urinary diversion were included in our study. The patients were divided into two groups according to the types of urinary diversion. One group consisted of 29 patients with ileal conduit and the other group consisted of 19 patients with ileal W neobladder. The mean age of the ileal conduit group and the ileal W neobladder group were 65.6+/-9.9 years and 60.8+/-8.3 years, respectively. The preoperative and postoperative blood urea nitrogen/creatinine (BUN/Cr) levels, postoperative complications and postoperative GFR, as measured by (99m)Tc-DTPA scans, were compared between the two groups. RESULTS: For the postoperative complications, stricture at the ureterovesical anastomosis site occurred in 1.7% (1/58 renal units) of the ileal conduit group and in 10.5% (4/38 renal units) of the ileal W neobladder group. Acute pyelonephritis occurred in 5.2% (3/58 renal units) of the ileal conduit group and in 5.3% (2/38 renal units) of the ileal W neobladder group. The pre- and postoperative serum BUN/Cr levels were 20.8/1.3 and 24.8/1.6, respectively, in the ileal conduit group, and 17.2/1.1 and 18.8/1.2, respectively, in the ileal W neobladder group. There were no statistical significant differences between the pre- and postoperative changes of the serum BUN/Cr levels for both groups. The GFR, as measured by (99m)Tc-DTPA scans, were 77.6 and 78.7ml/ min/1.73m2 in the ileal conduit group and the ileal W neobladder group, respectively. There were no statistical significant differences between the two groups. CONCLUSIONS: There were no significant differences in renal function between the ileal conduit and ileal W neobladder.

Retroperitoneal liposarcoma comprises 12 to 45 percent of all liposarcoma. It has been a therapeutic dilemma and a less prognosis because of its tendency to attain a tremendous size due to early silent growth and difficult wide en bloc excision in the retroperitoneum. Here in we report a case of retroperitoneal liposarcoma in 51 year old male patient with a brief review of the literatures.

Chronic sclerosing sialadenitis, also known as Kuttner tumor, is a chronic inflammatory disease of the salivary glands that is reported in a few cases in medical literature. Recent reports suggest that certain aspects of sclerosing diseases, including chronic sclerosing sialadenitis or dacryoadenitis, should be classified under immunoglobulin G4 (IgG4)-related sclerosing disease based on immunohistochemical studies. This study reports an unusual case of IgG4-related sclerosing disease appearing simultaneously in the lacrimal glands, submandibular glands, and extraocular muscles. A 56-year-old male presented with complaints of bilateral eyelid swelling and proptosis that began two years ago. Computed tomography confirmed that bilateral submandibular enlargements also existed five years ago in the subject. Orbital computed tomography and magnetic resonance imaging revealed bilateral lacrimal gland enlargement and thickening of extraocular muscles. Typical findings of chronic sclerosing dacryoadenitis were revealed upon pathologic exam of the right lacrimal gland. Immunostaining revealed numerous IgG4-positive plasma cells. Through these clinical features, we make a diagnosis of IgG4-relataed sclerosing disease in the subject.

Fabella impingement syndrome after total knee arthroplasty (TKA) is a rare condition. However, the location of the inserted prosthesis and the size of the fabella are considered major causative factors. Thus far, a conventional surgical excision of the impinged fabella is recommended treatment for the impingement. A 72-year-old woman was diagnosed with degenerative arthritis of the knee. She complained of fabella impingement due to an incompletely excised bony spur behind the posterolateral femoral prosthesis after TKA. The fabella and remaining bony spur were removed using an arthroscopic procedure. The impingement has not recurred and the range of motion (ROM) of the knee was improved after a 12 months follow-up. Arthroscopic surgery might be an alternative treatment for fabella impingement after TKA.

BACKGROUND: The value of plasma concentration of 8-Methoxypsoralen(8-MOP) in the supervision of photochemotherapy has been recognized. However, plasma levels of 8-MOP were not proportionate to the degree of PUVA induced erythema and couldn't alone predict the degree of PUVA induced erythemal reaction. We made a speculation that the degree of PUVA induced erythema might correlate better with skin tissue levels of 8-MOP than plasma levels. Suction blister fluid(SBF) has been known to represent tissue fluid in the skin. So we per-formed a study of comparison of 8-MOP concentrations in both plasma and SBF. OBJECTIVE: Our purpose was to evaluate the correlation of the concentrations of 8-MOP in plasma and SBF 2 hours after oral administration of 0.6 mg/kg of 8-MOP. METHODS: Twenty six patients, aged between 16 and 50 years, undergoing suction blister surgery for vitiligo treatment, participated in this open study. Single oral doses of 0.6 mg/kg of body weight of 8-MOP were taken. Blood samples(5ml) and SBF(2ml) were collected at 2 hours after the drug administration, and 8-MOP concentration in plasma and SBF were quantitated by reverse phase high-performance liquid chromatography (HPLC). RESULTS: 8-MOP concentrations in plasma and SBF ranged from 18 to 545 ng/ml and 8 to 179 ng/ml, respectively. On the analysis of linear regression, a close-relation could not be observed between two SBF levels; measured and predicted values which were calculated from measured plasma and SBF concentrations (r²=0.583, P < 0.001). CONCLUSION: The correlation of plasma and SBF concentrations of 8-MOP is weak. So, SBF levels of psoralen are recommended for the study of PUVA erythemal reactions.

BACKGROUND: Non-depolarizing muscle relaxants have their muscle relaxing effect by competing with acetylcholine (ACh) at the nicotinic receptor level. What are the effects of such muscle relaxants on the tracheal smooth muscle? This present study was set up to address the question as to how vecuronium and pancuronium influence the tracheal smooth muscle. METHODS: Sixty male Sprague-Dawley rat tracheal smooth muscles were isolated at optimal length for isometric force. The preparations were set up in an organ bath containing Tyrode's solution. And isometric force displacement transducer and physiograph were used to record the change in force. After the equilibration period the preparations were contracted with ACh 10(-5) M and carbachol 3x10(-7)M seperately. The preparations were washed with fresh tyrode's solution and allowed to return passively to resting tone. Then the cumulartive effect of ACh (from 3 10(-7) M through 10(-5) M) and carbachol (CCh, from 10(-8) M through 3 10(-6) M) were produced before and after pretreating the preparation with vecuronium (10(-5) M and 10(-6) M) and pancuronium (10(-5) M and 10(-6) M) respectively. Also, we studied the changes of contraction produced by neostigmine before and after pretreatment with vecuronium (10(-5) M and 3 10(-5) M) and pancuronium (3 10(-6) M and 3 10(-5) M). RESULTS: Vecuronium shifted the ACh dose-response curve of the tracheal contraction to the left (p<0.0001) and pancuronium shifted the curve to the right side (p<0.0001). However vecuronium shifted the carbachol dose-response curve to the right side as did pancuronium. Also the contraction effects of neostigmine after pretreatment with muscle relaxants decreased in the group pretreated with vecuronium (p<0.05) and a higher concentration of pancuronium (p<0.01), but with a low concentration of pancuronium the effect increased (p>0.05). CONCLUSIONS: Vecuronium inhibits the ACh hydrolyzing enzyme, especially acetylcholinesterase. Therefore it potentiates ACh contraction in the tracheal smooth muscle, but not the CCh contraction, while pancuronium has a different effect in comparison with vecuronium. That is, at a low concentration it reveals an antagonistic effect on the muscarinic M2 receptor and at a higher concentration it has an antagonistic effect on the muscarinic M3 receptor in the tracheal smooth muscle.

A case of Carney complex in a Korean patient is presented. The patient had the characteristics of Carney complex including skin lesions, positive family history, and multiple myxomas including a superficial angiomyxoma in the perianal area. An extensive genetic analysis revealed a novel mutation in the protein kinase A type I-a regulatory subunit (PRKAR1A) gene, but not in the phosphodiesterase type 11A (PDE11A) gene. This is the first case wherein extensive genetic studies were performed in a patient with Carney complex in Korea.

The purpose of this study was to evaluate the painrelief effect of intra-artieular morphine after knee arthroscopy. First, the authors selected 20 general anesthetic patients and divided them equally into 2 groups ; the control group, and the morphine group. Second, at the end of knee arthroscopy, we injected 1mg of preservative free morphine in 20ml normal saline solution into knee joint cavity of the morphine group, while we injected only 20ml normal saline solution to the control group. And tourniquet was inflated above knee joint for ten minutes after injection in each patient. Third, we measured changes of systolic arterial blood pressure(SABP), diastolic arterial blood pressure(DABP), heart rate(HR), and respiratory rate(RR) before operation and at 1, 2, 3, 4, 5, 6, 12, 24 hour after knee arthroscopy. Fourth, we also measured visual analogue scale(VAS), requirement of supplemental analgesics, and systemic side effects of morphine. The results were as follows ; 1. SABP, HR, RR were increased significantly(p<0.05) at 1 hour after intra-articular injection in control group, but SABP, DABP, HR, RR were not changed signifieantly in morphine group. 2. VAS was decreased significantly(p<0.05) in morphine group compared with conrol group at each period after intra-articular injection. 3. Supplemental analgesics were not required in morphine group at all. With these results, we could conclude that intra-articular morphine is effective for pain relief after knee arthroscopy without any side effect.
