Primary gastric adenocarcinoma is extremely rare in children. Here, we report an additional case of primary adenocarcinoma, located at the lesser curvature in a girl at the age of 2.5 years. She had no family history and no apparent underlying cause for the tumor. She died 4 months after admission despite complete resection of the mass and chemotherapy.

Single-port laparoscopic surgery (SPLS) is a surgical technique with many advantages over conventional laparoscopy. Its range of indications has expanded alongside the development of its unique tools and equipment. We are able to safely perform SPLS with the low-cost glove-port method without need of any specially developed SPLS port or the TriPort Access System. For this study, the files of patients who underwent laparoscopic surgeries performed between the dates of January 2013 and December 2014 at our clinic were reviewed. Umbilical access single-port abdominal surgeries which were performed using glove-port technique were included in the study. Two hundred nineteen patients who underwent SPLS surgery were included in the study. Of these patients, 158 (72.1%) were male and 61 (27.8%) were females. 58.4% of the cases were appendectomies (n = 128), 20% were orchidopexies (n = 44), 8.6% were orchiectomies (n = 19), 5.4% were ovarian cyst excisions (n = 12), 3.6% were varicocelectomies (n = 8), 2.2% were peritoneal dialysis catheter placements (n = 5), and 1.3% were nephroureterectomies (n = 3). In 67 cases (30.4%), Kirschner wire was used to eliminate the need for a second port. The study concludes that glove-port SPLS, which can readily be performed using conventional tools and Kirschner wire rather than expensive specially developed instruments, is a preferable technique because it is reliable, more cost-effective, and results in a scarless recovery.  相似文献

Human cells are exposed to exogenous insults and continuous production of different metabolites. These insults and unwanted metabolic products might interfere with the stability of genomic DNA. Recently, many studies have demonstrated that different psychiatric disorders show substantially high levels of oxidative DNA damage in the brain accompanied with morphological and functional alterations. It reveals that damaged genomic DNA may contribute to the pathophysiology of these mental illnesses. In this article, we review the roles of oxidative damage and reduced antioxidant ability in some vastly studied psychiatric disorders and emphasize the inclusion of treatment options involving DNA repair. In addition, while most currently used antidepressants are based on the manipulation of the neurotransmitter regulation in managing different mental abnormalities, they are able to prevent or reverse neurotoxin-induced DNA damage. Therefore, it may be plausible to target on genomic DNA alterations for psychiatric therapies, which is of pivotal importance for future antipsychiatric drug development.  相似文献

Pregnancy-associated plasma protein-A (PAPP-A) is potentially a proatherosclerotic metalloproteinase and a new inflammatory marker. Investigators sought to evaluate the significance of PAPP-A in patients with asthma. Blood samples were collected from 35 patients and 20 control subjects. Serum PAPP-A was determined by enzyme-linked immunosorbent assay. PAPP-A levels of patients with asthma (8.1±5.0 mU/L) were higher than those of the control group (4.9±2.1 mU/L) (P < .01). A significant correlation was noted between serum PAPP-A concentration and asthma severity (r=.581;P < .01). Investigators concluded that PAPP-A may contribute to airway smooth muscle hyperplasia as an insulin-like growth factor-dependent insulin-like growth factor-binding protein-4 protease in patients with asthma.  相似文献

The purpose of this study was to determine which commonly reported outcome measures best correlated with patient satisfaction after revision hip arthroplasty and to identify factors unrelated to hip status that may also play a role. From our institutional database, we identified 78 patients (80 hips) who underwent revision total hip arthroplasty and collected follow-up data. Patients with moderate or severe pain and those with limited walking ability reported significantly lower satisfaction scores. Harris hip score and patient-rated general health status were independently associated with patient satisfaction. Patient-rated anxiety and depression correlated inversely with satisfaction. Commonly reported outcome measures do reflect patient satisfaction after revision hip arthroplasty. However, satisfaction also appears to be influenced by psychologic factors.  相似文献
