Surgical outcome of synchronous second primary cancer in patients with gastric cancer

PURPOSE: In order to improve the likelihood of curative and safe gastric surgery, this study investigated the clinical features and surgical outcomes of gastric cancer with a synchronous cancer. PATIENTS AND METHODS: The clinicopathological data of 10,090 gastric cancer patients at Samsung Medical Center from September 1994 to December 2006 were retrospectively analyzed. Of them, 90 patients with gastric cancer and a synchronous second primary cancer underwent simultaneous surgery for gastric cancer and second primary cancer. The clinicopathological characteristics of the patients, surgical outcome, and prognosis were examined. RESULTS: The most common synchronous second primary cancer was colorectal cancer (37 patients), followed by hepatocellular carcinoma (13 patients), renal cell carcinoma (11 patients), and pancreatic carcinoma (5 patients). The incidence of a second primary cancer in the gastric cancer patients was higher than the incidence in the general population. Stage I gastric cancer patients had more synchronous cancers than stage II patients (59 vs. 31). Postoperative complications were encountered in 7 patients. Four patients underwent reoperation. Two patients died from hepatic failure and leakage of esophagojejunal anastomosis. The 5-year survival rate of stage I and II gastric cancer was 61% and 39%, respectively. CONCLUSION: Since gastric cancer patients with a synchronous second primary cancer are not rare, the possibility of synchronous cancers in gastric cancer patients should be considered. The prognosis of early stage gastric cancer patients with a synchronous second primary cancer was influenced more by the presence of the second primary cancer than by the gastric cancer itself.     

Multi-disciplinary treatment of a rare pelvic cavity ependymoma

Ependymomas usually develop from neuroectodermal organs. Here, we present an ependymoma arising from the pelvic cavity. A 27-year-old Korean female was admitted to the hospital with a sensation of abdominal fullness. Imaging studies revealed a huge heterogeneous nodular mass in the pelvis and lower abdomen. Laparotomy showed that two large masses with multiple nodules were located between the uterus and rectum and uterus and bladder, respectively. Histologically, the tumor was characterized by compact columnar neoplastic cells divided by fibrovascular septae. The neoplastic cells formed true ependymal rosettes and perivascular pseudorosettes. Immunohistochemical staining showed a strong positive reaction for glial fibrillary acidic protein (GFAP) and vimentin and a partial positive reaction for S100 and EMA. The tumor was thus diagnosed as an ependymoma arising from the pelvic cavity. The patient was treated with a debulking operation and chemotherapy based upon the in vitro chemosensitivity test results. The patient was free of cancer for 4 years following surgery. This is a rare case of extraneural ependymoma for which an in vitro chemosensitivity test was critical in determining the multidisciplinary approach for treatment.     

Positive-thinking and life satisfaction amongst Koreans

PURPOSE: The present study examined the positive-thinking and life satisfaction of the general Korean population. In particular, we examined the role of positive-thinking on participants' life satisfaction. MATERIALS AND METHODS: We conducted a telephone survey of 409 respondents (194 males, 215 females). The participants provided self-reports on their positive thinking, life satisfaction and demographic information. RESULTS: The results showed that age, education, occupation, and family income had an influence on positive- thinking as well as life satisfaction in Korea. Specifically, younger respondents and persons with high incomes or higher education degrees were more likely to have higher positive scores and thus higher life satisfaction scores. However, after controlling for the demographic variables, positive thinking significantly affected life satisfaction(R(2) Change=0.170, F= 88.56, p < 0.001). CONCLUSION: We provided empirical evidence that positive thinking may indeed play a significant role in life satisfaction. Therefore, positive thinking would offer important direction for the growth of life satisfaction and interventions aiming to remediate the effects of demographic variables on life satisfaction.     

Anti-inflammatory activity of compounds from the rhizome of <Emphasis Type="Italic">Cnidium officinale</Emphasis>

Five new compounds, 9,3′-dimethoxyhierochin A (1), 6-oxo-trans-neocnidilide (2), (±)-(3E)-trans-6-hydroxy-7-methoxydihydroligustilide (3), (±)-cnidiumin (4), and 6-(1-oxopentyl)-salicylic acid methyl ester (5), together with twenty known compounds (6–25), were isolated from the rhizome of Cnidium officinale. The chemical structures of new compounds were established by NMR spectroscopic techniques, mass spectrometry, Mosher’s method, and CD spectrum. Their anti-inflammatory activities were evaluated against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in macrophage RAW 264.7 cells. Compounds 7, 13, and 14 showed inhibitory effects with IC₅₀ values of 5.1, 24.5, and 27.8 μM, respectively. In addition, compounds 7, 13, and 14 reduced LPS-induced inducible nitric oxide synthase (iNOS) expression and cyclooxygenase-2 (COX-2) protein in a concentration-dependent manner.

Effect of natural extract eye drops in dry eye disease rats

AIM: To reveal a novel MITF gene mutation in Waardenburg syndrome (WS), which is an autosomal dominant inherited neurogenic disorder that consists of various degrees of sensorineural deafness and pigmentary abnormalities in the eyes, hair and skin. METHODS: The genetic analysis of the Chinese family was conducted by whole-exome sequencing, then the results were confirmed by Sanger sequencing. RESULTS: WS is classified into type I to IV, which are identified by the W index, clinical characteristics and additional features. The MITF gene mostly accounts for WS type II. In this study, a de novo heterozygous mutation in the MITF gene, c.638A>G in exon 7, was identified in the patient diagnosed with WS type I features, as the W index was 2.17 (over 2.10), with dystrophia canthorum, congenital bilateral profound hearing loss, bilateral heterochromia irides, premature greying of the hair, and excessive freckling on the face at birth. She also underwent refractive errors and esotropia, reduced pigmentation of the choroid and visible choroid vessels. The mutation was not found in previous studies or mutation databases. CONCLUSION: The novel mutation in the MITF gene, which altered the protein in amino acids 213 from the glutamic acid to glycine, is the genetic pathological cause for WS features in the patient. Those characteristics of this family revealed a novel genetic heterogeneity of MITF in WS, which expanded the database of MITF mutations and offered a possible in correcting the W index value of WS in distinct ethnicities. Moreover, ocular symptoms should be emphasized in all types of WS patients.     

Comparative Efficacy and Bioequivalence of Novel H1-Antihistamine Bepotastine Salts (Nicotinate and Salicylate)

Bepotastine salts (nicotinate and salicylate) were investigated for their physicochemical properties to develop novel salt forms of bepotastine, bioequivalent to the bepotastine besilate-loaded tablet (Talion). These bepotastine salts of either nicotinate- or salicylate-loaded tablets were prepared by conventional wet granulation method, and dissolution profiles and pharmacokinetics in beagle dogs were compared to those of Talion. A novel bepotastine nicotinate has a higher solubility at varying pH levels (1.2, 4, or 6.8) than salicylate-loaded or besilate-loaded salt. In addition, those bepostastine salt forms (nicotinate and salicylate) are stable in heat, light, and water. Further, the novel nicotinate- and salicylate-loaded tablets showed similar dissolution rates to Talion in several selected dissolution media and were bioequivalent to Talion in beagle dogs in terms of area under the concentration–time curve (AUC) and maximum observed concentration (C_max). A pharmacokinetic study performed in beagle dogs demonstrated that test and reference products were found to be bioequivalent in terms of safety, efficacy, and pharmacokinetic properties. These results suggest that bepostastine nicotinate and salicylate formulations are considered applicable candidates and are well tolerated versus the conventional bepostastine besilate formulation.     

Foot reconstruction using a serratus anterior muscle flap from the same donor site after failure of a thoracodorsal artery perforator flap

The free flap failure rate for the lower extremities is high, which adversely affects limb salvage efforts. In this article, we report a case of failure of a thoracodorsal artery perforator flap, which was simultaneously reconstructed with a serratus anterior muscle flap from the same donor site. A 56‐year‐old male patient had infected wound for 3 months due to Achilles tendon rupture. We reconstructed the defect using a thoracodorsal artery perforator flap. However, 2 days after the operation, we found the congested flap. We were obliged to discard the whole flap and harvested a serratus anterior muscle flap from the same donor site. The patient's foot healed uneventfully. After flap failure, the use of a second free flap from the same donor site may be an effective and safe procedure in specific cases. © 2013 Wiley Periodicals, Inc. Microsurgery 34:153–156, 2014.
