Separation of water-in-oil droplet is important in environmental protections, bioassays, and saving functional inks. So far, bulk oil-water separation has been achieved by membrane separation and sponge absorption, but micro-drop separation still remains a challenge. Here we report that instead of the "plug and go" separation model, tiny water-in-oil droplets can be separated into pure water and oil droplets through "go in opposite ways" on the curved peristome-mimetic surfaces in milliseconds without energy input...

Percutaneous endoscopic gastrostomy (PEG) is often the treatment of choice in head and neck cancer (HNC) patients needing long-term nutritional support. Prospective studies on PEG tube placement in an otorhinolaryngologist service are lacking. At our hospital, otolaryngologist-head and neck (ORL-HN) surgeons-have performed PEG insertions for HNC patients since 2008. We prospectively analyzed 127 consecutive HNC patients who received their PEG tubes at the Department of Otorhinolaryngology-head and neck surgery, and evaluated the outcome of PEG tube insertions performed by ORL-HN surgeons...

A stoma is an artificial opening to the skin formed when a part of the gastrointestinal tract is resected and opened to the skin in order to divert the bowel content to the skin surface. The incidence of stomal and peristomal complication varies from 30 to 67% with a significant negative impact on patient quality of life. Despite their prevalence, care providers tend to show insufficient awareness of peristomal skin complications, and research-based evidence related to peristomal skin complication and management options particularly in dermatology literature is sparse...

Rationale and key points This article discusses post-discharge care for patients following stoma formation. While the patient is taught the practicalities of managing the stoma appliance in hospital, this learning should be integrated into their daily life following discharge from hospital. Nurses are required to consider and address any issues that might affect the patient in the long term. These include changes in body image, adapting to having a stoma, preventing or treating complications associated with a stoma, and long-term follow-up...

The slippery peristome of the pitcher plant Nepenthes has attracted much attention due to its unique function for preying on insects. Recent findings on the peristome surface of Nepenthes alata demonstrate a fast and continuous unidirectional liquid transport, which is enabled by the combination of a pinning effect at the sharp edges and a capillary rise in the wedge, deriving from the multiscale structure, which provides inspiration for designing and fabricating functional surfaces for unidirectional liquid transport...

Tripneustes is one of the most abundant and ecologically significant tropical echinoids. Highly valued for its gonads, wild populations of Tripneustes are commercially exploited and cultivated stocks are a prime target for the fisheries and aquaculture industry. Here we examine Tripneustes from the Kermadec Islands, a remote chain of volcanic islands in the southwest Pacific Ocean that mark the boundary of the genus' range, by combining morphological and genetic analyses, using two mitochondrial (COI and the Control Region), and one nuclear (bindin) marker...

BACKGROUND AND STUDY AIMS:  Performing a percutaneous endoscopic gastrostomy (PEG) in head and neck cancer (HNC) patients can be challenging because of the presence of trismus, pharyngeal obstruction by tumor, and pharyngoesophageal strictures or fistula. Pharyngocutaneous fistula (PCF) is a major postoperative concern in patients submitted to total laryngectomy (TL). In the medical literature to date, the cervical fistula has been used as an access to PEG in only four reports. The aim of this study was to evaluate the safety of cervical fistula for insertion of a PEG tube...

Intestinal stomas are necessary for several colon and rectal conditions and represent a major change in the new ostomate's daily life. Though dehydration is the most frequent etiology requiring readmission, irritant contact dermatitis and a host of other peristomal skin conditions are more common complications for ostomates. Wound, ostomy, and continence nurses are invaluable resources to both ostomy patients and providers. A few simple interventions can prevent or resolve most common peristomal complications...

BACKGROUND: Primary skin tumors that develop at enteral feeding stomas are extremely rare. Ongoing surveillance of these stomas, including the peristomal skin, is essential to early diagnosis and treatment of these tumors. CASE: A 73-year-old man with an esophageal chemical burn caused by swallowing sodium hypochlorite (bleach) approximately 50 years earlier that was initially managed with esophageal exclusion and placement of a gastrostomy device for enteral feeding presented with an exophytic and painful mass of the skin adjacent to his gastrostomy site...

REVIEW
Brigitte Crispin
Peristomal irritation is one of the most common complications in patients with a stoma. In many cases, prevention is limited to the care provided during the post-operative period. However, it can start before the operation by improving the physical condition of the patient. It continues during the perioperative period with the surgical technique. Prevention advice can be given during these three key stages of the patient's treatment.

Bell-shaped ciliates of the subclass Peritrichia, such as Vorticella, Carchesium and Epistylis, are commonly found in freshwater and other aquatic environments, either solitary or colonial. Peritrichs attach to a substratum via a contractile or non-motile stalk, and collect food particles by water current using ciliary rows around the edge of the bell, called the peristome. Some peritrichs are epibiotic and ectocommensalistic associates of aquatic insects and other animals, settling on the surface of their specific hosts...

Approximately 1 million people are living with an ostomy, and 100 000 to 130 000 new ostomies are created each year. The exact incidence and prevalence of complications are unknown but have been reported to be as high as 70% and to affect quality of life (QoL). Using convenience sampling methods, a descriptive study was conducted to explore QoL scores and peristomal complications reported by adults with a permanent ostomy attending the 2009 United Ostomy Associations of America conference. Attendees who had a permanent ileostomy, colostomy, or urostomy; were at least 18 years of age; and able to read and speak English were invited to participate...

Percutaneous endoscopic gastrostomy (PEG) is the method of choice in patients requiring long-term enteral tube feeding. In patients with intrathecal baclofen infusion therapy (IBT) pump implantation, infection via the skin and soft tissue may be an issue of concern. The introducer technique for gastrostomy tube insertion may be useful in reducing the risk of peristomal infection. Although the presence of a PEG tube has been reported as a risk factor for implantation site infection (for newly inserted IBT pumps), whether existing IBT pumps are at risk for infection during or after the placement of a PEG tube is not clear...

INTRODUCTION: Low anterior resection (LAR) with total mesorectal excision (TME) represents the gold standard for patients with low rectal carcinoma. Protective ileostomy (PI) is commonly performed during LAR in an effort to protect low rectal anastomosis. The aim of this study is to analyse outcomes in our own patient population, focusing on morbidity associated with PI. METHOD: A retrospective clinical study of patients operated on between 2013 and 2015 was conducted in University Hospital Ostrava...
