Nanoparticle-Encapsulated Epirubicin Efficacy in the Inhibition of Growth of Orthotopic Ovarian Patient-Derived Xenograft in Immunocompromised Mice.

Epirubicin hydrochloride (EPI) is an anticancer drug widely used in the treatment of many solid tumors, including ovarian cancer. Because of its anatomical location, ovarian cancer shows symptoms when it is already in an advanced stage and is thus more difficult to treat. Epirubicin hydrochloride kills cancer cells effectively, but its dose escalation is limited by its severe toxicity.

Non-invasive obstetric anal sphincter injury diagnostics using impedance spectroscopy.

Obstetric anal sphincter injuries are the most common cause of fecal incontinence in women yet remain under-diagnosed. The aim of this study was to assess the suitability of impedance spectroscopy for diagnosing sphincter injuries arising during delivery. This was a prospective single-center study.

The DIAMOND system in the treatment of type 2 diabetes mellitus in an obese patient.

Obesity and type 2 diabetes mellitus have reached epidemic proportions worldwide. As the majority of antidiabetic medications are of limited efficacy and patient adherence to long-term therapy is one of the main limiting factors of effective blood glucose and body weight control, new therapies are still looked for. The DIAMOND system seems to be one of the most promising among them.

Migration of a foreign body into the colon and its autonomous excretion.

Background: The frequency of foreign body retention in the abdominal cavity ranges from 1 in 100 to 1 in 3000 surgeries performed. Worldwide literature describes only a few cases of the migration of misplaced surgical gauze into the colon.

Case Reports: The first case is a 60-year-old patient following laparoscopic cholecystectomy, who excreted (on his own) a cotton sheet 30 × 65 cm after 26 weeks, which did not possess a radiological locator.

Nissen fundoplication improves gastric myoelectrical activity characteristics and symptoms in gastroesophageal reflux patients: evaluation in transcutaneous electrogastrography.

Background: Gastric myoelectrical activity disorders play an essential role in the pathophysiology of gastroesophageal reflux disease (GERD), although little is known about gastric motility following surgical treatment of the disease. The aim of present study was to analyze the impact of Nissen fundoplication on both gastric myoelectrical activity, measured using the transcutaneous electrogastrography technique (EGG), and change in digestive symptoms.

Methods: In 43 patients with GERD, EGG was recorded before and after the Nissen procedure and compared with the EGG obtained in eight healthy volunteers.

Roux-en-Y or 'uncut' Roux procedure? Relation of intestinal migrating motor complex recovery to the preservation of the network of interstitial cells of Cajal in pigs.

We designed a conscious pig model to investigate myoelectric activity and the number of interstitial cells of Cajal (ICC) in the proximal jejunum following the Roux-en-Y and 'uncut' Roux procedures in relation to clinical outcomes. Twelve male Polish White pigs (8 weeks old, 10-13 kg) underwent surgery under general anaesthesia first to implant bipolar electrodes and telemetry transmitters for continuous electromyography recordings and then, after 1 week recovery, to create Roux-en-Y (n = 6) and 'uncut' Roux loops (n = 6). Upper gut tissue specimens were studied for the expression of c-kit staining procedure to quantitatively identify the presence of interstitial cells of Cajal.
