Echinococcus granulosus (E. granulosus) and Echinococcus multilocularis (E. multilocularis) infections are the most common parasitic diseases that affect the liver. The disease course is typically slow and the patients tend to remain asymptomatic for many years. Often the diagnosis is incidental. Right upper quadrant abdominal pain, hepatitis, cholangitis, and anaphylaxis due to dissemination of the cyst are the main presenting symptoms. Ultrasonography is important in diagnosis. The World Health Organization classification, based on ultrasonographic findings, is used for staging of the disease and treatment selection. In addition to the imaging methods, immunological investigations are used to support the diagnosis. The available treatment options for E. granulosus infection include open surgery, percutaneous interventions, and pharmacotherapy. Aggressive surgery is the first-choice treatment for E. multilocularis infection, while pharmacotherapy is used as an adjunct to surgery. Due to a paucity of clinical studies, empirical evidence on the treatment of E. granulosus and E. multilocularis infections is largely lacking; there are no prominent and widely accepted clinical algorithms yet. In this article, we review the diagnosis and treatment of E. granulosus and E. multilocularis infections in the light of recent evidence.

Gastric cancer has an important place in the worldwide incidence of cancer and cancer-related deaths. It can metastasize to the lymph nodes in the early stages, and lymph node metastasis is an important prognostic factor. Surgery is a very important part of gastric cancer treatment. A D2 lymphadenectomy is the standard surgical treatment for cT1N+ and T2-T4 cancers, which are potentially curable. Recently, the TNM classification system was reorganized, and the margins for gastrectomy and lymphadenectomy were revised. Endoscopic, laparoscopic and robotic treatments of gastric cancer have progressed rapidly with development of surgical instruments and techniques, especially in Eastern countries. Different endoscopic resection techniques have been identified, and these can be divided into two main categories: endoscopic mucosal resection and endoscopic submucosal dissection. Minimally invasive surgery has been reported to be safe and effective for early gastric cancer, and it can be successfully applied to advanced gastric cancer with increasing experience. Cytoreductive surgery and hyperthermıc intraperıtoneal chemotherapy were developed as a combined treatment modality from the results of experimental and clinical studies. Also, hyperthermia increases the antitumor activity and penetration of chemotherapeutics. Trastuzumab which is a monoclonal antibody interacts with human epidermal growth factor (HER) 2 and is related to gastric carcinoma. The anti-tumor mechanism of trastuzumab is not clearly known, but mechanisms such as interruption of the HER2-mediated cell signaling pathways and cell cycle progression have been reported previously. H. pylori is involved in 90% of all gastric malignancies and Japanese guidelines strongly recommend that all H. pylori infections should be eradicated regardless of the associated disease. In this review, we present innovations discussed in recent studies.

The frequency of advanced cancer was high in patients with high RDWvalues. High RDW values were strongly associated with short-term mortality although only a borderline relationship with overall survival was observed.

The aim of this study was to investigate the effects of surgical intervention for nasal pathologies on obstructive sleep apnea syndrome (OSAS) and continuous positive airway pressure (CPAP) titrations in patients with OSAS. The study was designed as a prospective case control study. Between December 2007 and June 2010, 31 patients (26 men and 5 women) who were diagnosed with OSAS with polysomnography and confirmed to have obstructive nasal pathology were enrolled in the study. The average age of the patients was 53 ± 9.6 (range 33-68 years) and the body mass index ranged from 22 to 40.6 kg/m(2) with an average of 30.3 ± 4.1. The patients were evaluated with Epworth Sleepiness Scale, OSAS Complaints Questionnaire, visual analog scale, and CPAP titration before and 3 months after nasal surgery. As three patients did not attend the control polysomnography, data analysis was performed on 28 patients. Although there was a significant improvement in the nasal passage and subjective complaints, namely, snoring frequency, apnea and daytime sleepiness, the difference between preoperative and postoperative AHI values was not statistically significant. Postoperative CPAP titration results indicated a decrease both in pressures and in AHI in comparison to preoperative values. These reductions were not statistically significant, although the decrease in CPAP pressures was close to significance (p = 0.062). Nasal pathologies should be treated in all patients with OSAS, particularly those undergoing CPAP treatment. However, patients should be counseled that favorable results might not be achieved after nasal surgery.

Although there was less adhesion formation with PTFE and oxidized cellulose, PTFE not only impaired the tensile strength, but also induced fibrosis and inflammation. An oxidized cellulose adhesion barrier can be safely used in incisional hernia repair to prevent intra-abdominal adhesions.
