Myoepithelial carcinomas are rare, malignant salivary neoplasms in which the tumor cells almost exclusively manifest myoepithelial differentiation. A 50-year-old man presented with an indolent movable submucosal mass of 10 years' duration on the right upper oral mucosa. The diagnosis of myoepithelial carcinoma originated from minor salivary gland was made by histopathologic and immunohistochemical evaluation.

OBJECTIVE: To evaluate the changes of plasma MMP-2, -9 levels in preeclampsia between antepartum and postpartum periods, and compare with normotensive pregnant. METHODS: Plasma MMP-2, -9 levels were determined with enzyme-linked immunoassay in pregnant women with preeclampsia (n=20) compared to control group (normotensive pregnant women) matched by maternal age, gestational age, and parity (n=20). RESULTS: Women with preeclampsia presented significantly higher plasma level of MMP-2 before delivery [516.33 +/- 98.75 vs 384.55 +/- 93.84 (ng/mL), p=0.002]. In postpartum 24 hours, women with preeclampsia exhibited higher plasma MMP-2 level compared control group [534.77 +/- 158.67 vs 336.04 +/- 139.11 (ng/mL), p=0.002]. But the plasma level of MMP-9 was significantly lower in preeclampsia group before delivery [26.26 +/- 7.49 vs 45.00 +/- 20.31 (ng/mL), p=0.001]. In postpartum 24 hours, women with preeclampsia also speculated lower plasma MMP-9 level compared control group, but no existence of significance. CONCLUSION: Plasma MMP-2 concentration is significantly increased in preeclampsia before delivey and postpartum 24 hours. Plasma MMP-9 concentration is significantly decreased in preeclampsia before delivery.

Osteogenesis imperfecta (OI) is an inherited disease of connective tissue disorder which represents a phenotypically heterogeneous group of conditions that results from a number of genetic defects in the synthesis of type I collagen. A pregnancy associated with osteogenesis imperfecta is considered a high risk pregnancy because the disease is associated with various metabolic and hematologic disorders, as well as well-recongnized skeletal abnormalities. In addition to the mother with OI, the offspring has about a 25% to 50% chance of being affected, therefore genetic counseling before conception and prenatal diagnosis should be offered to all affected mothers. Patients with OI present a series of problems and require a multidisciplinary approach in their management. We present a case of parturient with osteogenesis imperfecta with brief review of literature.

PURPOSE: We wanted to assess the benefits and safety of periarticular soft tissue injection of bupivacaine and morphine in total hip arthroplasty by conducting a prospective randomized trial. MATERIALS AND METHODS: Between February 2008 and January 2010, a prospective, randomized study was performed on fifty patients with an American Society of Anesthesiology stage of I or II. All the patients were administered COX-2 inhibitor and we used PCEA (Patient Controlled Epidural Analgesia) for 24 hours postoperatively. All the patients underwent their operation under general anesthesia. Fifty randomly selected patients were divided into two groups. After reduction of the hip joint, 50 ml of normal saline was intraoperatively injected into 25 patients (Group A) and 50 ml of locally injected analgesia that included 0.5 ml 5 mg of morphine HCL, 40 ml of 0.5% 50 mg chirocaine (Levo-bupivacaine) and 9.5 ml of normal saline was injected into the capsule and the soft tissue and muscle around the hip joint in 25 patients (Group B). The analgesic efficacy was evaluated by the visual analogue scale (VAS) at 6 and 12 hours postoperatively with the patients in a resting state and at 24, 48 and 72 hours postoperatively with the patients in a resting state and during a passive exercise (30degrees) state. The consumption of PCEA and additional analgesic drugs was also evaluated postoperatively. RESULTS: Significant differences were found between the 2 groups (P<0.05) with regard to the VAS at 6 and 12 hours postoperatively with the patients in a resting state and at 24, 48 and 72 hours postoperatively with the patients in a resting state and a passive exercise state. During 24 hours postoperatively, in the mixed analgesia injected group, the consumption of PCEA was significantly lower than that in the normal saline injected group (P<0.05). No significant differences were found for the consumption of additional analgesic drugs between the 2 groups (P>0.05). CONCLUSION: Intraoperative periarticular soft tissue injection of bupivacaine and morphine can significantly reduce pain and it can reduce the requirement for patient-controlled analgesia, with no apparent risks, following total hip arthroplasty.

BACKGROUND: The purpose of this study was to evaluate the usefulness of the pleural fluid carcinoembryonic antigen (CEA) and cytokeratin fragment 19 (CYFRA 21-1) tumor markers as complementary tools for the diagnosis of malignant pleural effusions. PATIENTS AND METHODS: The levels of pleural and serum CEA and CYFRA 21-1 were prospectively assayed in 222 patients with pleural effusions (150 benign effusions, 57 bronchogenic carcinomas and 15 metastatic carcinomas). RESULTS: The levels of pleural fluid CEA and CYFRA 21-1 in the malignant effusions were significantly higher than those in the benign effusions. With a specificity of 95%, the cut off values for the CEA and CYFRA 21-1 in pleural effusions were 5 and 89 ng/ml, respectively. The diagnostic sensitivities of the pleural fluid CEA and CYFRA 21-1 in malignant effusions were 72 and 54%, respectively, whereas using a combination of the two, the sensitivity increased to 87% (p<0.05). CONCLUSIONS : These findings suggest that a combination of the pleural fluid CEA and CYFRA 21-1 in pleural effusions can be useful in the diagnosis of malignant pleural effusions.

An ectopic pancreas in the gastrointestinal tract is mostly found incidentally and its malignant transformation is extremely rare. We report herein a rare case of malignant transformation of ectopic pancreas in the stomach, associated with gastric outlet obstruction. A 69-year-old woman was admitted to our hospital, complaining of vomiting. Esophagogastroduodenoscopy revealed an encircling submucosal tumor-like lesion on the prepyloric antrum showing outlet obstruction. Abdominal CT showed an enhancing mass on the antrum and PET CT showed hypermetabolic wall thickening. So we performed a subtotal gastrectomy. Surgical specimens showed a moderately differentiated ductal adenocarcinoma, and the tumor cells were strongly positive for cytokeratin 7. The tumor was located close to the ectopic pancreas tissue. The tumor showed subserosal and omental invasion. There was one lymph node metastasis and no distant metastasis. The patient is being followed up in the outpatient department.

BACKGROUND: Primary varicose veins are caused by a retrograde blood flow and increased hydrostatic pressure as a result of an increase in height or in physical strain associated with work. Treatment for varicose vein involves 1) conservative management - periodic leg elevation, elastic stocking support, and exercise with stocking support, 2) sclerotherapy, and 3) surgery. METHODS: Ninety-two limbs with primary varicose veins of the lower limb were operated on from Jan. 1996 to Dec. 1996. RESULTS: The prevalent age group consisted of those patients between 50 and 60 years old, and the female to male ratio was 2 : 1. Varicose veins developed in the right lower limb in 48 cases, in the left lower limb in 37 cases, and in both lower limbs in 7 cases. Presumed etiological factors included occupations requiring long periods of standing in 13 male cases, and pregnancy in 26 female cases. The average duration of illness was 12.5 8.6 years. Of the 92 cases operated on, a greater saphenous vein (GSV) high ligation (HL) and above knee (AK) stripping with varicosectomy (VS) was done in 38 cases, a GSV HL and total stripping with VS in 4 cases, a short saphenous vein (SSV) HL and VS in 14 cases, an external banding valvuloplasty of GSV and VS in 29 cases, an external banding valvuloplasty only in 2 cases, a Linton's operation in 2 cases, a GSV branch ligation and VS in 1 case, and sclerotherapy in 2 cases. The reduction rates of venous volume (VV) and ambulatory venous pressure (AVP) were 15 19% and 33 33%, respectively, after stripping. The reduction rates of VV and AVP were 19 18% and 33 36%, respectively, after valvuloplasty. Postoperative complications were wound complication in 1 case in the AK stripping group; postoperative numbness in 3 cases and wound complication in 1 case in the total stripping group; and wound complication in 1 case, GSV thrombosis in 2 cases, postoperative bleeding in 1 case, and postoperative reflux in 1 case in the valvuloplasty group. CONCLUSIONS: Generally, postoperative conditions were good and complications were negligible. In the stripping group, postoperative numbness developed only in the total stripping group. Between the valvuloplasty and the stripping groups, there was no significant hemodynamic difference.

PURPOSE: The altered gantry angle during scanning for some multiplanar reconstruction CT program (CT/MPR) may cause distortion of the image. The aim of this study was to ascertain whether there is a image distortion in a reformatted image when the gantry and the object are equally inclined using ToothPix and DentaScan program. MATERIALS AND METHODS: A resin block model with four cylindrical holes and a human dry mandible were used. Two MPR software packages, ToothPix and DentaScan program, were used for reformatted panoramic images. The block and the gantry were equally inclined at 0degree, 15degrees, and 30degrees. RESULTS: With ToothPix program, a resin block model with empty holes and a dry mandible showed inclined images in the reformatted panoramic image. Increasing the gantry angle, the depth and inclination of the holes were increased in the reformatted central panoramic images. However, a resin block model with gutta percha in its holes and a dry mandible with a wire in its mandibular canal didn't show image distortion. With DentaScan program, image distortion was not seen in any situation. CONCLUSION: ToothPix program may distort the reformatted image when the gantry angle is not at zero degrees. However, with DentaScan program, the patient may be positioned comfortably and the gantry can be adjusted to the patient positioning.

BACKGROUND: Lung cancer is the leading cause of malignant pleural effusions, which is currently most commonly treated using pleurodesis via bedside thoracostomy. Several agents had been used for the treatment of pleural sclerosis, but with differing efficacies and associated side effects. Our purpose with this study was to compare the efficacy, side effects and disease free survival times of patients being treated with OK-432 and doxycycline sclerotherapy in lung cancer induced malignant pleural effusions. PATIENTS AND METHODS: 79 patients who underwent pleurodesis with OK-432 and doxycycline, between Jan. 1994 and Aug. 2001, were retrospectively reviewed. Resopnses 30 days following pleurodesis were determined from chest radiographs, with the disease free survival time being evaluated according to the response. RESULTS: The success rates, 30 day followint pleurodesis, with OK-432 and doxycycline 83 and 87%, respectively (p=0.677). With regard to the side effects, fever was more common when OK-432 was used (59%, p=0.001), and pain was more common with doxycycline use (73%, p=0.008). There was no significant difference in disease free survival times between OK-432 (13.6 Months) and doxycycline (11.6 Months) (p=0.532). CONCLUSION: with the use of OK-432, for pleurodesis, was as effective as doxycycline, can be considered as an alternative treatment for malignant effusion in patients with lung cancer.
